SHOCK IMMOBILIZATION AND STABILIZATION PLATFORM

TECHNICAL FIELD

Invention is a shock immobilization and stabilization platform comprising; sensors that measure the shocks, linear electrical actuators mounted on a fixed floor, control mechanism that operates the system and mobile upper platform.

BACKGROUND

In our days, stabilization platforms are used in defense industry, professional film studios and building floors in the areas which have a high potential of earthquake.

But the implementation of these systems to transportation vehicles has not been taken place yet. Besides, these systems are mostly used for shock absorption instead of floor stabilization. These systems, which aim to absorb the balance disrupting powers that come from the bottom before they reach to floor, do not have a purpose to hold the floor without corrupting its angle with the plane. And there is no similarity between working mechanism of the floor stabilization systems and the active suspension systems which are used in vehicles.

SUMMARY OF THE INVENTION

Invention eliminates the shocks which are a disadvantage especially in transportation industry. Basically, this is a system comprising shock measuring sensors, linear electrical actuators mounted on a fixed floor, control mechanism that controls the system and mobile upper platform. In the land vehicles, aircrafts and vessels, the unwanted forces (shocks) that effect the vehicle during the transportation are measured by the sensors and the control mechanism calculates the necessary position information then sends it to the actuators. Thus, the counter effect of the measured shocks is sent to the mobile platform and the upper platform provides the stabilization on two rotational axes. The mobile upper platform always stays stabile on two rotational axes. MEANINGS OF THE FIGURES

Connection Element between the L Connection Equipment and Upper Platform (8):

It a connection element that is connected to L connection equipment (7) and it is formed by two merged bearings. It provides an enlargement for the movement plane of the platform and it is included in the system because of the shapes of the connection forms of actuators.

Electronic Control Unit (10):

It is an electronic control unit (10) placed on the lower floor fixed plate (2), comprising; control mechanism, power supply, safety fuses and sensors. Linear Electrical Actuator (3):

It functions with an included rotational electrical motor and it moves the rods back and forth by transforming the rotational movement to linear movement by special transforming equipment. There are two different sized and featured linear electrical actuators (3) on the platform. And they are mounted to the platform lower actuator fixing leg (4) with a universal bearing.

Vertical Linear Electrical Actuator (11):

It is a vertical linear electrical actuator (1 1 ) mounted vertically to the platform lower actuator fixing leg (4) and it provides the vertical linear movement to the mobile upper platform (1 ). It functions with an included rotational electrical motor and it moves the rods back and forth by transforming the rotational movement to linear movement by special transforming equipment. Vertical Linear Electrical Actuator Rod (11.2):

It a rod included in the actuator which provides the up and down movement of the mobile upper platform (1 ). The axial joint included in the linear electrical actuator (3) provides the linear movement by moving back and forth in specific ratios and transmission of the movement to the system.

Actuator Electrical Motor (5):

It is a rotational electrical motor which supplies power to move the axial joint included in the linear electrical actuator (3). Electrical Motor Connection Apparatus (5.1):

It is a two piece apparatus that gives one directional movement ability which is placed behind the platform bottom actuator fixing leg (4) and electrical motor.

Linear Electrical Actuator Rod (3.1):

The axial joint included in the linear electrical actuator (3) provides the linear movement by moving back and forth in specific ratios and transmission of the movement to the system.

Linear Electrical Actuator End Bearing (3.2):

It is an element comprising a special inner bearing which rotationally transmits the linear movement of the electrical linear actuator in one direction.

Gyroscope Sensors (12) and Accelerometer Sensors (13):

They are placed on the mobile upper platform (1 ). Gyroscope and accelerometer sensors measure the forces that effects the platform and they also measure if the mobile upper platform (1 ) is on desired position values or not.

Shock immobilization and stabilization platform measures the forces that effect the floor which platform is mounted on with gyroscope sensors (12) and accelerometer sensors (13) in three axes. In the electronic control unit (10) of the system, information that comes from the sensors is analyzed and with the PID (Proportional, Integral, Derivative) control method the direction and speed information is calculated and sent to the related linear electrical actuators (3). After sending the information to the linear electrical actuators (3), thanks to continuous control, reference values, which are entered to the system by the user, are compared to the information comes from feedback and a difference is calculated. For reducing the difference to minimum, that procedure goes continuously. Thus, desired stabilization procedure is implemented with minimum errors.

Four linear electrical actuators (3) are positioned to mid-point of the floor of the platform with an angle of 90 degrees to each other. The other vertical linear electrical actuator (1 1 ) is mounted perpendicularly to the upper platform to increase the movement ability of the system. Because of that positioning, upper platform (1 ) obtains maximum movement ability for stabilization in roll and pitch rotational axis. Linear electrical actuators (3) send feedback to the control mechanism with the included feedback sensors and the platform's movement ability is adjusted in desired levels.

System is a shock immobilization and stabilization platform that can be fixed to the floor where the system going to be used with the lower floor fixed plate (2). Actuator electrical motors (5) are connected to the platform lower actuator fixing leg (4), which is connected to mid-point center of the lower floor fixed plate (2), by electrical motor connection apparatus (5.1 ). Linear electrical actuators (3) and vertical linear electrical actuator (1 1 ) manipulate the linear electrical actuator rods (3.1 ) and vertical linear electrical actuator rod (1 1 .1 ) with the power which is generated by the actuator electrical motors (5). These manipulations are controlled by the electronic control unit (10) regarding to information comes from gyroscope sensors (12) and accelerometer sensors (13). Linear electrical actuator end bearing (3.2), which is connected to the vertical linear electrical actuator rod (1 1 .2) and linear electrical actuator rod (3.1 ), transmits the linear movement as a one-directional rotational movement to the L connection equipment (7) which is connected to the L connection equipment fixing apparatus (6). That movement is transmitted to the mobile upper platform (1 ) by connection element between the I connection equipment and upper platform (8). As a result, mobile upper platform (1 ) performs the stabilization process in three axes with the information sent to the linear electrical actuators (3) by electronic control unit (10).

The shock immobilization and stabilization platform can be implemented to the vehicles which are used in transportation and it will bring a solution to the situations in which no shocks or no quakes are needed. The shock immobilization and stabilization platform can be placed in cabinet or trailer parts of the commercial vehicles which make sensitive transportation. So it can bring a lot of advantages and prevent trading loss. For example, placing the shock stabilization platform in the cabinet of an ambulance would make sure the transportation of a patient and health officer without having a shock or a quake during the transportation. Besides health officers can do their jobs more easily. Those advantages can be counted in the novelties which the system is going to provide.
