Description:
Sunvisor Mechanism with Magnetic Switching Circuit Element

Technical Field

The invention is related to a sunvisor mechanism which comprises circuit elements that trigger the illumination element magnetically based on opening and closing of the mirror in the sunvisor used in vehicles in the automotive sector.

The invention is particularly related to a sunvisor mechanism which reduces costs by decreasing the amount of conductive elements used within the mechanism by means of the magnetic triggering element.

State of the Art

Today in the automotive sector, sunvisors which are located on the front portion of the vehicles are used for concealing the sun lights coming from the front glass or side windows for the driver and the passenger who sits in front of the vehicle. In many vehicles, sunvisors are widely used which are located manually to the front and side regions of the vehicle by means of the driver or the passenger according to the direction of the coming sun lights. On the sunvisors generally there are makeup mirrors with illumination for the passenger part which are in small sizes. The illuminations located on the makeup mirrors are designed in a manner such that they will be active when the lid covering the mirror is opened. Therefore in the environment where illumination is not sufficient and where the mirror is required to be used, the activation of the illumination is enabled.

In the current art, there are two long copper conductive elements for transmitting the electric circuit within the mechanism to the illumination element. When the mirror cover located within the sunvisor is brought to the open condition by the user, the copper conductive elements contact with each other. As a result of the contact of the copper conductive elements together with the completion of the electric circuit, the circuit is transmitted to the illumination element and it is lighted. When the mirror cover is closed then the contact of the copper conductive elements is cut and then the illumination element is also brought to the closed state. The copper conductive elements used within the current mechanism substantially increases the total cost of the material. In addition to this during the opening and closing motion of the cover, due to mechanical contact of the copper conductive elements, it prevents homogenous sliding motion because it applies a varying force. The current mechanism has a disadvantage except the above mentioned deficiencies due to noise formation based on the mechanical contact and thus this bothers the user.

As a result due to above mentioned disadvantages and the insufficiency of the current solutions in terms of the subject, an improvement in the relevant technical field is required.

Aim of the Invention

The invention aims to solve the above mentioned disadvantages by means of being inspired from the current conditions.

The main aim of the invention is to provide a sunvisor mechanism which enables triggering the illumination element within the sunvisor in a magnetic manner by means of the sliding shutter.

Another aim of the invention is to enable stable motion of the sliding shutter by means of the circuit elements triggered in a magnetic manner without any mechanical contact.

Another aim of the invention is to enable silent motion of the sliding shutter by means of a magnetic triggering process.

Another aim of the invention is to enable improvement of the costs by decreasing the amount of copper conductive elements to which mechanical contact is made.

The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

Detailed Description of Drawing

In this detailed description the preferred embodiments of the sunvisor mechanism (A) are described only in a manner such that the subject is clarified without creating any limiting effect.

In Figure 1 , the perspective view of the inventive sunvisor mechanism (A) is given. In this manner the invention essentially consists of; an outer cover (10) on which all elements of the mechanism take place, a guide shaft (20) which forms the rotational axis for opening and closing the sunvisor, a triggering element (40) which enables to open and close the illumination by completing the electric circuit by means of the motion of the movable cover (30) which makes triggering within the sunvisor, a conductive element (50) which enables transmitting the electric flow, a magnetic element (60) which forms the required magnetic field for completing the circuit by the triggering element (40), a pushing element (70) which enables the magnetic element (60) approaching and moving away from the triggering element (40) and a bedding element (80) which enables engagement of the movable cover (30) and the pushing element (70).

The outer cover (10) which constitutes the main support structure of the sunvisor mechanism (A) and enables it’s opening and closing at the required angle, carries the other elements of the mechanism thereon. The guide shaft (20) which enables opening, closing and rotational motion of the outer cover (10) also enables the electrical connection between the vehicle and the sunvisor mechanism (A) by means of the electric circuits. The outer cover (10) houses the mirror and illumination element within the movable cover (10) which is engaged thereon. When the movable cover (30) is brought to open status by means of sliding in a horizontal manner, the triggering element (40) known as reed switch in the art is also in active status then the electrical circuit is completed and energy is given to the illumination element by means of the current flow. When the movable cover (30) is closed, the triggering element (40) passes to the passive status and the current flow from the electric circuit is cut and then the illumination element is closed. The transmission of the electric current from said elements is provided by means of a conductive element (50) which is preferably a copper plate or copper wire. In order to reduce the material cost of the conductive element (50), copper plated material or cables can also be used.

In Figure 2, a detailed view of the inventive sunvisor mechanism (A) is given. In this manner in order to compete the electrical circuit by means of operating in connection with the triggering element (40), the task of forming the required magnetic field is performed by means of the magnetic element (60). The magnetic element (60) which is preferably a magnet moves in a manner such that it is connected on the bedding element (80). Together with the opening of the movable cover (30), the bedding element (80) moves together with the magnetic element (60) connected thereon by means of the pushing element (70). Therefore by enabling contact between the magnetic element (60) and the triggering element (40), the circuit is completed by means of enabling the transmission of the electric current coming over the guide shaft (20) through the conductive elements (50). Therefore the electric current transmitted through the conductive elements (50) passed through the illumination element and brings it to open condition. The pushing element (70) which is preferably a leaf spring moves in a manner such that it returns back to its initial position while the movable cover (30) is brought to the closed condition, enables to cut the contact between the magnetic element (60) and the triggering element (40). In this case, due the power cut which passes through the conductive element (50), the illumination element passes to the closed condition.

In case bedding element (80) is not possibly used, the magnetic element (60) can be molded integrally with the movable cover (30). In this case, the simultaneous motion of the magnetic element (60) and the movable cover (30) is enabled, and in the same operating principle, contact is made with the triggering element when the movable cover (30) is open, on the other hand the contact is terminated with the triggering element (40) when the movable cover (30) is closed and thus the electric current is also cut. In order to realize said designs, the magnetic elements (60) can be selected as a ferrite magnet, strip magnet or plate magnet.

In addition to said operating method, in case the outer cover (10) is closed while the movable cover (30) is opened, the conductive elements (50) located on the guide shaft (20) will change their direction. Therefore together with the insulating surface of the guide shaft (20), the contact of the conductive elements (50) is enabled and the illumination element is brought to the closed condition by means of preventing the transmission of the electric current over the guide shaft (20).
