The invention relates to a control mechanism of a vehicle bodywork lid, in particular a lid of filling or charging vehicle module, wherein the lid of the filling or charging module is mounted in swinging manner in a fixed bodywork part using at least one arm, support end of which is arranged on the lid inside and the carrying end of which is arranged pivotally using a support pin in the fixed body part, wherein an electric motor is arranged in the fixed body part, the output drive shaft (31) of which is in gear engagement via a transmission with a driven gear mounted fixedly on the support pin firmly connected to the lid arm.

Background

Electric drive vehicles and vehicles with combined drive including electric drive are of special interest to manufacturers and the public, especially due to further tightening of regulations, further significantly limiting the permitted values of combustion engine emissions. The electric drive vehicles draw energy from batteries, which must be charged from an external source. For charging, a charging module is arranged in the bodywork, usually on the vehicle side, having a multi-pole electrical socket arranged in the bottom of the dish- shaped bulge of the bodywork. The orifice of the dish-shaped bulge is covered by an outer lid, and the electrical socket or a part thereof is covered by an inner lid. The outer lid of the charging module is usually hung using one arm pivotally mounted on the bodywork support pin. From the applicant's internal sources, the outer lid of the charging module is known to be hung using two arms forming a parallelogram and mounted on two parallel-arranged support pins of the bodywork. The inner lid of the charging module is preferably pivotally mounted on one of the support pins of the bodywork using one arm. With the advanced state of the art, the requirements of vehicle owners for the simplification of vehicle operation are increasing as well, resulting in the implementation of electric drives to almost all moving bodywork parts, such as doors, covers, and lids of the charging modules. Electric drives of the lids, known so far, are limited to simply opening and closing the outer lid of the charging module. Other necessary functions of the lids of the charging modules must be controlled manually or by devices, separately or remotely controlled by a vehicle driver.

Summary of the Invention

The object of the invention is the electric control mechanism of a vehicle bodywork lid, which, in addition to the electric drive of the outer lid of the charging module, provides the locking of the outer lid in an open or possibly also in a closed position.

Shortcomings of the prior art are eliminated substantially, and the object of the invention is fulfilled by the control mechanism of the vehicle bodywork lid, wherein the lid of the filling or charging module is mounted in the fixed bodywork part in swinging manner using at least one arm, support end of which is arranged inside of the lid and the support end of which is arranged pivotally in the fixed bodywork part, wherein the electric motor is arranged in the fixed bodywork part, the output drive shaft of which is in gear engagement via transmission with a driven gear mounted firmly on the support pin firmly connected to the lid arm of the invention; characterised in that one of the transmission gears or an additional transmission gear connected to one of the transmission gears is engaged with a blocking element slidably mounted in the fixed part of the bodywork for the blocking element to engage with or disengage from a catch arranged on the lid or on one of the arms while blocking the lid position.

According to a preferred embodiment of the invention, one of the gears of the transmission or the additional transmission gear connected to one of the gears of the transmission on the front face may be provided with an axial guiding protrusion extending into a recess formed in the blocking element. Preferably, the blocking element may be provided with a locking finger arranged on one side and a compression spring arranged on the other side for power transmission with the fixed bodywork part for the blocking element to engage with or disengage from ίthe lid catch or the catch of one of the arms while locking the lid position. Preferably, an arc-shaped axial blocking protrusion, which engages with the shaped recess of the blocking element, may be formed on the front face of the gear engaging the blocking element in order to lock the position of the blocking element.

In particular, the advantages of the control mechanism of the vehicle charging module lid according to the invention consist in full automation and full electrical control of closing and opening of the outer lid of the vehicle charging module, together with automatic locking of the outer lid in the closed or open position.

I Exemplary embodiment of the invention

According to Fig. 1, the charging module 2.is arranged in the fixed part of the bodywork 1, formed by the dish-shaped bulge 3 with the bottom 4 and the charging socket 5 arranged in the bottom 4, To close the charging module 2, the lid 6 is arranged, which is mounted in the fixed part of the bodywork 1 using arms 10, 11forming a parallelogram. Using the carrying pins 14, 15, the lid 6 is hinged on the carrying ends 12, 13of the arms 10, 11, the opposite support ends 16, 17of which are rotatably mounted on support pins 18, 19arranged in the bodywork. Further, the electric motor 30is arranged in the fixed part of the bodywork 1, the output drive shaft 31of which is provided with the drive gear 32being in gear engagement with the first gear 33a of the transmission 33. The transmission 33 consists of gears 33a, 33b, 33c, 33d, 33e, and 33f for gear reducer. The last gear 33f of the transmission 33is in engagement with the driven gear 35 firmly connected to the support pin 18. The arm 10of the lid 6 is mounted on the support pin 18 and firmly connected to it. In one direction of rotation of the driven gear 35, the arm 10of the lid 6 rotates counter-clockwise and the lid 6 covers the opening of the dish- shaped bulge 3 of the charging module 2. In the opposite direction of rotation of the driven gear 35, the arm 1 0rotates clockwise and the lid 6 is released and exposes the opening of the dish-shaped bulge 3 of the charging module 2. The transmission gear 33f, which is a part of the transmission 33, is provided with an axial guiding protrusion 37 in the shape of a pin on its front face. A slide guiding is formed in the fixed bodywork part, where the blocking element 37 is slidably mounted to move slidably substantially in the direction of a tangent to a circle having its centre in the axis of the transmission gear 33f. The blocking element 36 has the shaped recess 38, with which the axial guiding protrusion 37 engages in a part of its circular path. In the open position of the lid 6, the axial guiding protrusion 37 of Fig. 1 does not engage with the shaped recess 38 of the blocking element 36but is located on the opposite side of its circular path, opposite to the shaped recess 38. To lock the open position of the lid 6, the axial blocking protrusion 42 in the shape of an arc is formed on the front face of the transmission gear 33f; in the open position of the lid 6, this protrusion engages with the shaped recess 43 of the blocking element 36 in shape transmission, thereby the blocking element 36 is locked in position corresponding to the open position of the lid 6.

According to Fig. 2, when the transmission gear 33f is rotated clockwise, the shape transmission is released between the axial blocking protrusion 42 and shaped recess 43 of the blocking element 36, thereby releasing the blocking element 36 for subsequent sliding movement. Upon further rotation of the transmission gear 33f clockwise, the axial guiding protrusion 76 engages with the shaped recess 38 of the blocking element 36 and moves the blocking element 36 in the direction of a tangent to a circle centred on the axis of the transmission gear 33f. As the transmission gear 33f continues to rotate, the driven gear 35 further rotates in the opposite direction to the transmission gear 33f, and the arm 10moves the lid 6 to a position closing the opening of the dish-shaped bulge 3 of the charging module 2 as shown in Fig. 2. Upon further rotation of the transmission gear 33f, the guiding protrusion 37 moves the blocking element 36 into engagement with the catch 8 formed inside of the lid 6 Iand locks the position of the blocking element 36 in the closed position of the lid 6. The axial guiding protrusion 37 may be formed on one of the gears of the transmission 33or on any additional gear connected to one of the gears of the transmission 33. The shaped recess 38 is open so that when the transmission gear 33f further rotates, the axial guiding protrusion 37 disengages from the shaped recess 38 of the blocking element 36. The blocking element 36 remains in the position inserted into the catch 8 of the lid 6 due to the pressure of the compression spring 41, one end of which is in contact with the fixed part of the bodywork 1 and the opposite end is in contact with the inner bottom of the blocking element 36. The blocking element 36 is disengaged from the catch 8 arranged on the lid 6 when the transmission gear 33f is rotated counter-clockwise, i.e. in the opposite direction to the one when the lid is being closed. The axial guiding protrusion 37 engages with the recess 38 of the blocking element 36 and moves the blocking element 36 in the direction of release from the catch 8 of the lid 6 against the pressure of the compression spring 41. Rotation of the transmission gear 33f counter clockwise causes rotation of the driven gear 35 and the arms 10, 11 of the lid 6 in the clockwise direction, making the lid 6 of the dish-shaped bulge 3 of the charging module 2 open. The lid 6 thus returns to its open position shown in Fig.1. The catch 8 may be formed either inside the lid 6 or on one of the arms 10, 11. The axial guiding protrusion 37 and the axial blocking protrusion 42 may be formed on one of the gears of the transmission 33 or on the additional gear 34 connected to one of the gears of the transmission 33, as well as on the front face of the driven gear 35. In order the blocking element 36 toengage with or disengage from the catch 8 of the lid 6 or the catch arranged on one of the arms 10, 11when blocking the jposition of the lid 6, the blocking element 36 may be preferably provided with the locking finger 39 on one side. To lock the position of the blocking element 36 in the catch 8 the

Icompression spring 41 is arranged on the other opposite side of the blocking element 36 for power transmission with the fixed part of the bodywork 1. Referring to Fig. 3, from a perspective view, an arrangement of the transmission 33with the transmission gear 33f that engages with the driven gear 35 is apparent. The shape of the axial blocking protrusion 42 in the shape of a circular arc with its centre in the axis of the transmission gear 33f is apparent as well. Finally, the embodiment of the blocking protrusion 36 with the locking finger on one side and the compression spring

41 arranged between the fixed part of the bodywork 1 and the inner bottom of the blocking element 36 is apparent.
