[0023] In the development of automotive seats, it is often necessary to conduct experiments on various performance aspects of the seat, such as electric testing of the sliding rail motor (front / rear), electric testing of seat cushion height adjustment, electric testing of the tilt adjustment motor, testing of seat belt switch signals, airbag resistance testing, testing of the electrical function of the multi-level heater, testing of the seat ventilation function, testing of the seat's multi-level massage function, testing of the electric seat memory function, and testing of the zero-gravity seat function. These tests are conducted to comprehensively verify the electrical control functions of the seat and the reliability of components such as the seat frame and sliding rails during long-term use. However, the testing of seat functions is often done manually, making it difficult to collect relevant data in real time.

[0024] This invention proposes a device for testing the function of an automobile seat.

[0025] Please see Figure 1 In one embodiment of the present invention, the automotive seat 4 functional testing device is used to test an automotive seat 4 having an actuator and a first sensor. The automotive seat 4 functional testing device includes a testing platform 1, a control device, and a second sensor. The testing platform 1 is used for fixed installation of the automotive seat 4. The control device is disposed on the testing platform 1 and is used to electrically connect the actuator and the first sensor of the automotive seat 4. The second sensor is electrically connected to the control device and is disposed on the automotive seat 4 to detect the state of the automotive seat 4.

[0026] In the technical solution of this invention, the test platform 1 provides installation and fixation for the car seat 4. After the car seat 4 to be tested is installed on the test platform 1, the control device can control the operation of the car seat 4's actuator by electrically connecting the control device to it. By electrically connecting the first sensor to the control device, the control device can acquire the feedback signal transmitted by the first sensor to obtain the state of the car seat 4. Furthermore, by placing the second sensor on the car seat 4, the second sensor can provide feedback on the current state of the car seat 4. Through the first and second sensors, the control device can receive and record real-time data of the car seat 4, thus improving the overall ability to collect relevant data in real time.

[0027] The test platform 1 is provided with multiple ball bearings on its underside, and multiple rollers are used to move the test platform 1. The rollers have a self-locking function to fix the position of the test platform 1. The control device, the execution device, and the first sensor can be connected by any feasible electrical connection method, which is not limited here; the type of the second sensor is set according to the test function, and correspondingly, the position of the second sensor on the car seat 4 is set according to the test function.

A headrest 45 is disposed on the upper side of the backrest 42.

[0029] The vehicle seat 4 functional testing device also includes two mounting rails 11. These two mounting rails 11 are used to fix the vehicle seat 4 in place. Both mounting rails 11 extend along a first horizontal direction and are spaced apart along a second horizontal direction. The first and second horizontal directions are perpendicular to each other. By fixing the vehicle seat 4 to the mounting rails 11, the vehicle seat 4 can be fixed to the testing platform 1. The mounting rails 11 can be connected to the vehicle seat 4 through multiple fixing points. Specifically, the vehicle seat 4 has two fixing points on the mounting rails 11. The fixing method between the vehicle seat 4 and the mounting rails 11 can be set as needed and is not limited here. For different vehicle seats 4, the installation of different vehicle seats 4 can be adapted by adjusting the distance between the two mounting rails 11. The mounting rails 11 are aluminum alloy rails.

[0030] The control device includes a controller and an I / O module. The I / O module is electrically connected to the controller and the second sensor, and is also used to electrically connect the actuator and the first sensor.

[0033] The test platform 1 is equipped with a control cabinet 2, and the control device is located inside the control cabinet 2. By placing the control device inside the control cabinet 2, the control device can be protected, reducing its exposure.

[0034] The control device also includes a power adapter, relays, a motor forward / reverse module, and electrical auxiliary components. The motor forward / reverse module is connected to the motor inside the car seat 4 to control the motor inside the car seat 4 to switch between forward and reverse rotation, thereby switching the motor inside the car seat 4 to the corresponding operating state.

[0035] Please see Figure 2 This invention also proposes a method for testing four functions of a car seat. This method is used in the aforementioned car seat four-function testing device. The specific structure of the car seat four-function testing device is as described in the above embodiments. Since this car seat four-function testing device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0036] Based on the current requirement testing mode, determine the type of execution device and execution parameters.

[0037] After acquiring the test mode, the control device can determine the corresponding test mode and the execution device corresponding to the test mode, and obtain the execution parameters of the corresponding execution device according to the content of the test mode.

[0038] The execution parameters are used to control the operation of the corresponding type of execution device.

During and after the execution of the execution devices, the first sensor and the second sensor detect the state of the car seat 4. The real-time data from the first sensor and the second sensor can be used as feedback parameters as test results to evaluate the function of the car seat 4.

The difference between the start and end points of the steering motor 41 is detected by a sensor to determine the actual drive stroke of the steering motor 41. The actual drive stroke and actual drive speed of the corresponding steering motor 41 are used as feedback parameters to evaluate the steering motor 41 of the car seat 4.

When the demand test is in heating test mode, one or more of the seat cushion heating element and the backrest 42 heating element can be selected to operate, using the temperature of the seat cushion and backrest 42 as feedback parameters to test and evaluate the heating function of the car seat 4. The first sensor can be a temperature sensor 5, and at least two are provided. The two temperature sensors 5 are respectively located on the seat cushion and the backrest 42 to detect the temperature of the seat cushion and the backrest 42 respectively.

[0047] By supplying air with a preset power through the negative pressure air supply component, the air supply pressure can be detected by a vacuum negative pressure detector.
