As shown in the seventh drawing, when the universal test circuit board 100 of the present embodiment needs to verify the function of the front low-profile power seat (not shown, corresponding to the power seat PA1b of the prior art), only the control box 200 needs to be assembled to the universal test circuit board 100, then the transceiver unit 7 is electrically connected to the front low-profile driving module 400, and then the seat test switching unit 3 is controlled to be electrically connected to the front seat driving unit 11, and the lumbar support test switching unit 6 is controlled to be electrically connected to the low-profile lumbar support driving unit 14.
As mentioned above, the user can make the seat switch module 2 send the seat operation signal S11 to the seat test switching unit 3 through the operation of the seat adjusting knob 2011, make the seat switch module 4 send the seat operation signal S12 to the universal seat back driving unit 13 through the operation of the seat adjusting knob 2012, and make the lumbar support switch module 5 send a lumbar support operation signal S13a to the lumbar support test switching unit 6 through the operation of the high lumbar support adjusting member 202.
Because the seat test switching unit 3 is electrically connected to the front seat driving unit 11, the front seat driving unit 11 sends a front seat driving signal S111 to the transceiver unit 7 according to the seat operation signal S11, and then the transceiver unit 7 sends the front seat driving signal S111 to the front low power distribution driving module 400 to control the front low power distribution power seat to adjust to a seat state position; in this embodiment, since the seat motor devices of the front low power distribution power seat and the front high power distribution power seat are the same in structure, the front low power distribution driving module 400 and the front high power distribution driving module 300 can share the front seat driving signal S111.
Similarly, since the back motor devices of the front low power distribution power seat and the front high power distribution power seat are the same in the present embodiment, the front low power distribution driving module 400 and the front high power distribution driving module 300 can share the common back driving signal S121 to control the front low power distribution power seat to adjust to a back state position.
In addition, in the present embodiment, since the lumbar support test switching unit 6 is switched to be electrically connected to the low lumbar support driving unit 14, the lumbar support operation signal S13a sent by the lumbar support switch module 5 is sent to the low lumbar support driving unit 14, and the low lumbar support driving unit 14 sends a low lumbar support driving signal S131a to the transceiver unit 7 according to the lumbar support operation signal S13a, and then the low lumbar support driving signal S131a is sent to the front row low lumbar support driving module 400 through the transceiver unit 7, so as to control the front row low lumbar support power seat to adjust to a low lumbar support state position.
In the present embodiment, since the low lumbar support driving signal S131a generated by the low lumbar support driving unit 14 is only the lumbar support inward movement driving signal or the lumbar support outward movement driving signal, when the lumbar support operation signal S13a received by the low lumbar support driving unit 14 is the lumbar support upward signal or the lumbar support downward signal, the low lumbar support driving unit 14 will not generate the corresponding driving signal, but will generate the corresponding lumbar support inward movement driving signal or the lumbar support outward movement driving signal only when the lumbar support operation signal S13a is the lumbar support inward movement signal or the lumbar support outward movement signal.
Referring to fig. 8, fig. 8 is a block diagram showing a system for testing a rear-row power seat by using a universal test circuit board of the power seat according to a preferred embodiment of the invention. As shown in the eighth diagram, when the universal test circuit board 100 of the present embodiment needs to verify the function of the rear-row power seat (not shown, corresponding to the power seat PA1c of the prior art), only the control box 200 needs to be assembled to the universal test circuit board 100, then the transceiver unit 7 is electrically connected to the rear-row driving module 500, and then the seat test switching unit 3 is controlled to be electrically connected to the rear-row seat driving unit 12.
As mentioned above, the user can make the seat switch module 2 send a seat operation signal S11a to the seat test switching unit 3 through the operation of the seat adjusting button 2011, and make the seat switch module 4 send a seat operation signal S12 to the universal seat back driving unit 13 through the operation of the seat adjusting button 2012.
Since the seat test switching unit 3 is electrically connected to the rear seat driving unit 12, the rear seat driving unit 12 sends the rear seat driving signal S111a to the transceiver unit 7 according to the seat operating signal S11a, and then the rear seat driving signal S111a is transmitted to the rear driving module 500 through the transceiver unit 7 to control the rear electric seat to adjust to a seat state position.
Similarly, in the present embodiment, since the back motor device of the rear-row power seat is configured identically to the back motor device of the front-row low-power seat and the back motor device of the front-row high-power seat, the rear-row driving module 500 can share the common back driving signal S121 to control the rear-row power seat to adjust to a back state position.
In addition, since the rear electric seat is not provided with the lumbar support motor device, the high lumbar support adjusting element 202, the lumbar support switch module 5, the lumbar support test switching unit 6 and the low lumbar support driving unit 14 are not required to be used when verifying the functions of the rear electric seat.
In practical applications, if the universal test circuit board 100 of the present invention needs to be connected to the front high-power driving module 300, the front low-power driving module 400 and the rear driving module 500 for performing the functional verification test, the front high-power driving module 300 needs to be connected to the transceiver unit 7 and the lumbar support test switching unit 6, and the front low-power driving module 400 only needs to be connected to the transceiver unit 7, so that the front low-power driving module 400 can be tested before the front high-power driving module 300, and the rear driving module 500 needs to be used by the rear seat driving unit 12 and the front high-power driving module 300 and the front low-power driving module 400 to be different from the front seat driving unit 11.
Therefore, the user can first electrically connect the transceiver unit 7 to the front-row low-profile driving module 400 for testing; after the front-row low-profile driving module 400 is tested, the user can connect the transceiver integration unit 7 to the front-row high-profile driving module 300, connect the lumbar support test switching unit 6 to the front-row high-profile driving module 300, and then switch the lumbar support test switching unit 6 to be electrically connected to the front-row high-profile driving module 300 to test the front-row high-profile driving module 300; finally, after the front-row high-power driving module 300 is tested, the user only needs to change the transceiver integration unit 7 to be electrically connected to the rear-row driving module 500 and change the seat test switching unit 3 to be electrically connected to the rear-row seat driving unit 12, so that the rear-row driving module 500 can be tested.
In the above three tests of the front high-power driving module 300, the front low-power driving module 400 and the rear driving module 500, the invention can complete all the tests by using the front high-power control box 200 only through the alternate connection of the transceiver integration unit 7 and the switch of the seat test switching unit 3 and the waist support test switching unit 6, and does not need to cooperate with the front high-power driving module 300, the front low-power driving module 400 and the rear driving module 500 to respectively produce test boards for verification test, thereby effectively reducing the production cost and shortening the development time of the circuit board.
In summary, in order to be able to share the tests of the front high-power-distribution electric seat, the front low-power-distribution electric seat and the rear electric seat, the universal test circuit board of the present invention mainly uses the seat test switching unit to selectively send the seat operation signal generated by the operation of the seat switch module to the front seat driving unit or the rear seat driving unit so as to drive the seats of the front high-power-distribution electric seat and the rear electric seat to operate; the invention also utilizes the waist support test switching unit to selectively send the waist support operation signal generated by the waist support switch module to the low-matched waist support driving unit or the front row high-matched driving module so as to drive the waist support of the front row high-matched and front row low-matched electric seat to actuate. In addition, the seat bases of the front high-allocation driving module and the front low-allocation driving module are the same specification, and the seat backs of the front high-allocation driving module, the front low-allocation driving module and the rear driving module are the same specification, so that the invention can control the seat base actuation of the front high-allocation and front low-allocation electric seats by utilizing the cooperation of the seat base switch module and the front seat base driving unit, and control the seat back actuation of the front high-allocation electric seats, the front low-allocation electric seats and the rear electric seats by utilizing the cooperation of the seat back switch module and the seat back driving unit.
As can be seen from the above description, the universal test circuit board of the electric seat of the present invention only needs to be assembled with the front high-level control box, and then selectively connected with the front high-level driving module, the front low-level driving module or the rear driving module, so that the operation function of the front high-level, front low-level or rear electric seat can be verified on the universal test circuit board, thereby effectively reducing the development time of the circuit board for three types of electric seats and reducing the production cost.
The foregoing detailed description of the preferred embodiments is intended to more clearly describe the nature and spirit of the invention and is not intended to limit the scope of the invention by the preferred embodiments disclosed above. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the scope of the invention as defined by the appended claims.
