Similarly, since in this embodiment, the seat back motor device of the rear row electric seat is the same structure as the seat back motor device of the above-mentioned row low distribution electric seat and front row high configuration electric seat, so the rear row drive model The group 500 can share the common seatback driving signal S121 to control the rear electric seats to be adjusted to a seatback state position.

In addition, since the rear electric seat is not equipped with a lumbar support motor device, it is not necessary to use the high-end lumbar support adjustment element 202, lumbar support switch module 5, and lumbar support test switch when verifying the functions of the rear electric seat. Unit 6 with low profile lumbar drive unit 14.

In actual operation, if the universal test circuit board 100 of the present invention needs to be connected to the front row high configuration driver module 300, the front row low configuration driver module 400 and the rear row driver module 500 for functional verification tests, due to the front row The high configuration driver module 300 needs to be connected to the transceiver integration unit 7 and the lumbar support test switching unit 6, while the front row low configuration driver module 400 only needs to be connected to the transceiver integration unit 7, so the test of the front row low configuration driver module 400 can Before the front-row high-configuration drive module 300, the rear-row seat drive unit 12 required by the rear-row drive module 500 and the front-row seats used by the front-row high-configuration drive module 300 and the front-row low-configuration drive module 400 The seat driving units 11 are all different, and in order to effectively improve the test efficiency in the present invention, the seat test switching unit 3 is electrically connected to the front seat driving unit 11 by default, and the lumbar support test switching unit 6 is electrically connected by default The lumbar support drive unit 14 is configured at the bottom.

In this way, the user can first electrically connect the transceiver integration unit 7 to the front-row low-profile driver module 400 for testing; Connect to the front-row high-end drive module 300, and connect the lumbar support test switching unit 6 to the front-row high-end drive module 300, and then switch the lumbar support test switching unit 6 to be electrically connected to the front-row high-end drive module 300, In order to test the front-row high-end drive module 300; finally, after the front-row high-end drive module 300 is tested, the user only needs to change the transceiver integration unit 7 to be electrically connected to the rear drive module 500, and The seat test switching unit 3 is changed to be electrically connected to the rear seat driving unit 12, so that the rear driving module 500 can be tested.

In the above three tests of the front-row high-configuration drive module 300 , the front-row low-configuration drive module 400 , and the rear-row drive module 500 , the present invention only requires the alternate connection of the transceiver integration unit 7 and the seat test switching unit 3 With the switching control of the lumbar support test switching unit 6, all the tests can be completed by using the control box 200 of the front row high configuration, without the need to cooperate with the front row high configuration drive module 300, the front row low configuration drive module 400 and the rear row drive module A group of 500 is used to produce test boards for verification testing, which effectively reduces production costs and shortens the development time of circuit boards.

To sum up, in order to be able to share the test of the general test circuit board of the present invention with the electric seat with high configuration in the front row, the electric seat with low configuration in the front row and the electric seat in the rear row, the seat test switching unit is mainly used to test the seat The seat operation signal generated by the operation of the seat switch module is selectively sent to the front seat drive unit or the rear seat drive unit, so as to drive the seat seats of the front seat and the rear electric seat to move; and the present invention also Use the lumbar test switching unit to selectively send the lumbar operation signal generated by the lumbar switch module to the low-profile lumbar drive unit or the front-row high-profile drive module, so as to drive the front-row high-profile and front-row low-profile The lumbar support of the power seat operates. In addition, since the seat seats of the front row high-configuration drive module and the front row low-configuration drive module are all of the same specification, and the seat backs of the front row high-configuration drive module, front row low-configuration drive module, and rear row drive module They are all of the same specification, so the present invention can use the cooperation of the seat switch module and the front seat drive unit to control the movement of the electric seats of the front row high configuration and the front row low configuration, and use the seat back switch module The combination of the group and the seatback drive unit controls the movement of the seat backs of the front high-profile electric seats, the front low-profile electric seats and the rear electric seats.

It can be seen from the above description that the universal test circuit board of the electric seat of the present invention only needs to be assembled with the control box of the front row high configuration, and then the universal test circuit board is selectively connected to the front row high configuration drive module, the front row low configuration The drive module or rear drive module can verify the operation function of the front row high configuration, front row low configuration or rear electric seat on the general test circuit board, so as to effectively reduce the use of three types of electric seats The board development time schedule, and thus reduce production costs.

Through the above detailed description of the preferred embodiments, it is hoped that the characteristics and spirit of the present invention can be described more clearly, and the scope of the present invention is not limited by the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equivalent arrangements within the scope of the claimed patent scope of the present invention.
