However, when the corresponding buttons of the local switch circuit and the boss button switch circuit are pressed at the same time and the adjustment directions are opposite, the control circuit of the seat motor will be disconnected, and the seat adjustment function cannot be realized. Utility Model Content

[0003] This application provides a seat switch circuit, a seat control system, and a vehicle, such that the adjustment priority of the boss button switch circuit is higher than the adjustment priority of the local switch circuit.

[0004] A seat switch circuit includes a boss key switch circuit and a local switch circuit; The first terminal of the boss button switch circuit is connected to the first terminal of the seat motor, the second terminal of the boss button switch circuit is connected to the second terminal of the seat motor, the third terminal of the boss button switch circuit is connected to the power supply terminal, and the fourth terminal of the boss button switch circuit is connected to ground, forming a boss button control loop.

[0005] In this embodiment, the boss button switch circuit is connected to both ends of the seat motor, the power supply terminal, and ground to form an independently controlled boss button control loop. The switching state of the boss button switch circuit directly controls whether the boss button control loop is on or off, thus enabling independent adjustment of the seat state based on the corresponding switch button. The local switch circuit is connected to both ends of the seat motor, the boss button switch circuit, the power supply terminal, and ground to form a jointly controlled local control loop. When the boss button switch circuit controls the boss button control loop to be off, the local control loop can be controlled to be on based on the switching state of the local switch circuit. This ensures that the adjustment priority of the boss button control loop is higher than that of the local control loop, so that when the switch buttons corresponding to both switch circuits are pressed simultaneously, the adjustment operation corresponding to the boss button control loop is executed first.

[0006] In one embodiment, the boss key switch circuit includes a first switch branch and a second switch branch; The first end of the first switch branch is connected to the first end of the seat motor, the second end of the first switch branch is connected to the first end of the seat motor through the local switch circuit, the third end of the first switch branch is connected to the power supply end, and the fourth end of the first switch branch is connected to ground. The first end of the second switch branch is connected to the second end of the seat motor, the second end of the second switch branch is connected to the second end of the seat motor through the local switch circuit, the third end of the second switch branch is connected to the power supply terminal, and the fourth end of the second switch branch is connected to ground. The first switch branch and the second switch branch are linked for control. When the boss key control circuit is on, the local switch circuit is disconnected from the power supply terminal and ground. When the boss key control circuit is off, the local switch circuit is connected to the power supply terminal and ground.

[0007] In this embodiment, by controlling the switching states of the first switch branch and the second switch branch, when the boss key control loop is turned on, the local control loop is turned off; and when the boss key control loop is turned off, the connection branch between the local switch circuit and the power supply terminal and ground is turned on. According to the switching state of the local switch circuit, the local switch circuit is controlled to be turned on, so that the adjustment priority of the boss key control loop is higher than the adjustment priority of the local control loop.

[0008] In one embodiment, the first switch branch includes a first single-pole double-throw switch and a first single-pole single-throw switch; the second switch branch includes a second single-pole double-throw switch and a second single-pole single-throw switch. The moving contact of the first single-pole double-throw switch is used to connect to the first end of the seat motor, and the two stationary contacts of the first single-pole double-throw switch are respectively connected to the power supply terminal and ground; the moving contact of the second single-pole double-throw switch is used to connect to the second end of the seat motor, and the two stationary contacts of the second single-pole double-throw switch are respectively connected to the power supply terminal and ground; the first single-pole double-throw switch and the second single-pole double-throw switch form the first linkage branch; The moving contact of the first single-pole single-throw switch is connected to the first terminal of the seat motor through the local switching circuit, and the moving contact of the second single-pole single-throw switch is connected to the second terminal of the seat motor through the local switching circuit. Either the moving contact of the first single-pole single-throw switch or the moving contact of the second single-pole single-throw switch is connected to the power supply terminal, and the other is connected to ground; the first single-pole single-throw switch and the second single-pole single-throw switch form a second linkage branch. The first linkage branch and the second linkage branch are linked for control; when one of them is turned on, the other is turned off.

[0009] In this embodiment, a first linkage branch is formed based on the first single-pole double-throw switch and the second single-pole double-throw switch, and a second linkage branch is formed based on the first single-pole single-throw switch and the second single-pole single-throw switch. When the first linkage branch and the second linkage branch are linked for control, the boss key control loop corresponding to the first linkage branch can be turned on, while the local control loop corresponding to the second linkage branch can be turned off, so that the adjustment priority of the boss key control loop is higher than the adjustment priority of the local control loop.

[0010] In one embodiment, the first switch branch includes a first double-pole triple-throw switch, the first moving contact of the first double-pole triple-throw switch is connected to the first end of the seat motor, the second moving contact of the first double-pole triple-throw switch is connected to the first end of the seat motor through the local switch circuit, and the three stationary contacts of the first double-pole triple-throw switch are respectively connected to the power supply terminal, ground and the power supply terminal; The second switch branch includes a second double-pole triple-throw switch. The first moving contact of the second double-pole triple-throw switch is connected to the second terminal of the seat motor. The second moving contact of the second double-pole triple-throw switch is connected to the second terminal of the seat motor through the local switch circuit. The three stationary contacts of the second double-pole triple-throw switch are respectively connected to ground, power supply terminal and ground. The first double-pole triple-throw switch and the second double-pole triple-throw switch are linked to control each other so that when one of the third linkage branch formed by the first moving contact of the two double-pole triple-throw switches and the fourth linkage branch formed by the second moving contact of the two double-pole triple-throw switches is turned on, the other is turned off.

[0011] In this embodiment, a third linkage branch is formed based on the first moving contacts of the first double-pole triple-throw switch and the second double-pole triple-throw switch, as well as the two stationary contacts connecting the power supply terminal and ground. A fourth linkage branch is formed based on the second moving contacts of the first double-pole triple-throw switch and the second double-pole triple-throw switch, as well as the two stationary contacts connecting the power supply terminal and ground. When the third linkage branch and the fourth linkage branch are linked for control, the boss key control circuit corresponding to the third linkage branch can be turned on, while the local control circuit corresponding to the fourth linkage branch can be turned off, so that the adjustment priority of the boss key control circuit is higher than the adjustment priority of the local control circuit.

[0017] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] This application provides a seat switch circuit, such as... Figure 1 , Figure 2 and Figure 8 As shown, the seat switch circuit includes a boss key switch circuit 1 and a local switch circuit 2. The first terminal of the boss key switch circuit 1 is connected to the first terminal of the seat motor M, the second terminal of the boss key switch circuit 1 is connected to the second terminal of the seat motor M, the third terminal of the boss key switch circuit 1 is connected to the power supply terminal BAT, and the fourth terminal of the boss key switch circuit 1 is connected to ground GND, forming a boss key control loop. The first terminal of the local switch circuit 2 is connected to the first terminal of the seat motor M, the second terminal of the local switch circuit 2 is connected to the second terminal of the seat motor M, the third terminal of the local switch circuit 2 is connected to the power supply terminal BAT through the boss key switch circuit 1, and the fourth terminal of the local switch circuit 2 is connected to ground GND through the boss key switch circuit 1, forming a local control loop.

[0019] As an example, the first and second terminals of the boss button switch circuit 1 are connected to the two ends of the seat motor M, respectively. The third and fourth terminals of the boss button switch circuit 1 are connected to the power supply terminal BAT and ground GND, respectively, allowing the user to directly control the rotation of the seat motor M and adjust the seat state by operating the boss button switch circuit 1. The first and second terminals of the local switch circuit 2 are connected to the two ends of the seat motor M, respectively. The third terminal of the local switch circuit 2 needs to be connected to the power supply terminal BAT through the boss button switch circuit 1, and the fourth terminal of the local switch circuit 2 needs to be connected to ground GND through the boss button switch circuit 1. This ensures that the conduction of the local control loop depends not only on the switching state of the local switch circuit 2 but also on the switching state of the boss button switch circuit 1. The adjustment priority of the boss button switch circuit 1 is higher than that of the local switch circuit 1, providing a guarantee.

[0020] In this embodiment, the boss key switch circuit 1 is connected to both ends of the seat motor M, the power supply terminal BAT, and ground GND, forming an independently controlled boss key control loop. The switching state of the boss key switch circuit 1 directly controls whether the boss key control loop is on, thus achieving independent adjustment of the seat state based on the switch button corresponding to the boss key switch circuit 1. The local switch circuit 2 is connected to both ends of the seat motor M, the boss key switch circuit 1, the power supply terminal BAT, and ground GND, forming a jointly controlled local control loop. When the boss key switch circuit 1 controls the boss key control loop to be off, the local control loop can be controlled to be on based on the switching state of the local switch circuit 2. That is, when the user presses the switch button corresponding to the boss key switch circuit 1, regardless of whether the user presses the switch button corresponding to the local switch circuit 2, the boss key control loop is on while the local control loop is off. When the user does not press the switch button corresponding to the boss key switch circuit 1, the boss key control loop is off, but the connection branch between the local switch circuit 2 and the power supply terminal BAT and ground GND is on. In this case, whether the local control loop is on can be determined based on whether the user presses the switch button corresponding to the local switch circuit 2. This design allows the adjustment priority of the boss key control loop to be higher than that of the local control loop. When the user presses the switch button corresponding to the boss key switch circuit 1 and the switch button corresponding to the local switch circuit 2 at the same time, the boss key control loop is turned on while the local control loop is turned off, so that the adjustment operation corresponding to the turned-on boss key control loop is executed first.

[0021] In one embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, the boss key switch circuit 1 includes a first switch branch 11 and a second switch branch 12. The first end of the first switch branch 11 is connected to the first end of the seat motor M, the second end of the first switch branch 11 is connected to the first end of the seat motor M through the local switch circuit 2, the third end of the first switch branch 11 is connected to the power supply terminal BAT, and the fourth end of the first switch branch 11 is connected to ground GND. The first end of the second switch branch 12 is connected to the second end of the seat motor M, the second end of the second switch branch 12 is connected to the second end of the seat motor M through the local switch circuit 2, the third end of the second switch branch 12 is connected to the power supply terminal BAT, and the fourth end of the second switch branch 12 is connected to ground GND. The first switch branch 11 and the second switch branch 12 are linked for control. When the boss key control loop is on, the local switch circuit 2 is disconnected from the power supply terminal BAT and ground GND. When the boss key control loop is off, the local switch circuit 2 is connected to the power supply terminal BAT and ground GND.

[0022] As an example, in the boss key switch circuit 1, the first end of the first switch branch 11 and the first end of the second switch branch 12 are respectively connected to the two ends of the seat motor M. The third and fourth ends of the first switch branch 11 and the second switch branch 12 are respectively connected to the power supply terminal BAT and the ground GND, so that the seat motor M cooperates with the first, third and fourth ends of the first switch branch 11 and the first, third and fourth ends of the second switch branch 12 to form a boss key control loop that can control the seat motor M to rotate forward or backward. Accordingly, the second end of the first switch branch 11 is connected to the first end of the seat motor M through the local switch circuit 2 (specifically, the third single-pole double-throw switch S21), and the second end of the second switch branch 12 is connected to the second end of the seat motor M through the local switch circuit 2 (specifically, the fourth single-pole double-throw switch S22). The third and fourth ends of the first switch branch 11 and the second switch branch 12 are respectively connected to the power supply terminal BAT and ground GND, so that the seat motor M, the first switch branch 11, the second switch branch 12, and the local switch circuit 2 cooperate to form a local control loop. Figure 1 As shown, local switch circuit 2 (specifically, the third single-pole double-throw switch S21) is connected to the power supply terminal BAT through the second and third terminals of the first switch branch 11, while local switch circuit 2 (specifically, the fourth single-pole double-throw switch S22) is connected to ground GND through the second and fourth terminals of the second switch branch; or, as Figure 2 As shown, the local switch circuit 2 (specifically the third single-pole double-throw switch S21) is connected to ground GND through the second and fourth terminals of the first switch branch 11, while the local switch circuit 2 (specifically the fourth single-pole double-throw switch S22) is connected to the power supply terminal BAT through the second and third terminals of the second switch branch 12.

[0023] In this example, by controlling the switching states of the first switch branch 11 and the second switch branch 12, the local control circuit is disconnected when the boss key control circuit is turned on; and when the boss key control circuit is turned off, the connection branch between the local switch circuit 2 and the power supply terminal BAT and ground GND is turned on. According to the switching state of the local switch circuit 2, the local switch circuit 2 is turned on so that the adjustment priority of the boss key control circuit is higher than the adjustment priority of the local control circuit.

[0024] In one embodiment, such as Figure 1 and Figure 2As shown, the first switch branch 11 includes a first single-pole double-throw switch S11 and a first single-pole single-throw switch S12; the second switch branch 12 includes a second single-pole double-throw switch S13 and a second single-pole single-throw switch S14; the moving contact of the first single-pole double-throw switch S11 is used to connect to the first terminal of the seat motor M, and the two stationary contacts of the first single-pole double-throw switch S11 are respectively connected to the power supply terminal BAT and ground GND; the moving contact of the second single-pole double-throw switch S13 is used to connect to the second terminal of the seat motor M, and the two stationary contacts of the second single-pole double-throw switch S13 are respectively connected to the power supply terminal BAT and ground GND; the first single-pole double-throw switch S11 and the second single-pole double-throw switch S14... The double-throw switch S13 forms the first linkage branch; the moving contact of the first single-throw switch S12 is connected to the first terminal of the seat motor M through the local switch circuit 2, and the moving contact of the second single-throw switch S14 is connected to the second terminal of the seat motor M through the local switch circuit 2. Either the moving contact of the first single-throw switch S12 or the moving contact of the second single-throw switch S14 is connected to the power supply terminal BAT, and the other is connected to ground GND; the first single-throw switch S12 and the second single-throw switch S14 form the second linkage branch; the first linkage branch and the second linkage branch are linked for control, and when either one is on, the other is off.

[0025] As an example, the moving contact of the first single-pole double-throw switch S11 and the moving contact of the second single-pole double-throw switch S13 are respectively used to connect the first end and the second end of the seat motor M. The two stationary contacts of the first single-pole double-throw switch S11 and the two stationary contacts of the second single-pole double-throw switch S13 are respectively connected to the power supply terminal BAT and the ground GND. The first single-pole double-throw switch S11 and the second single-pole double-throw switch S13 form the first linkage branch, so that the first single-pole double-throw switch S11 and the second single-pole double-throw switch S13 cooperate to make the boss key control circuit conduct, control the seat motor M to rotate forward or reverse, so as to adjust the seat state.

[0026] The first single-pole single-throw switch S12 is set between the local switch circuit 2 and the power supply terminal BAT, and the second single-pole single-throw switch S14 is set between the local switch circuit 2 and ground GND. Alternatively, the first single-pole single-throw switch S12 is set between the local switch circuit 2 and ground GND, and the second single-pole single-throw switch S14 is set between the local switch circuit 2 and the power supply terminal BAT. The first single-pole single-throw switch S12 and the second single-pole single-throw switch S14 form a second linkage branch, which can control whether the local switch circuit 2 is connected to the power supply terminal BAT and ground GND.

[0027] The following examples illustrate several operating states of the seat switch circuit in this example: like Figure 3As shown, when the local switch circuit 2 is not in operation, when the switch button corresponding to the boss key switch circuit 1 is pulled upward, the first single-pole double-throw switch S11 contacts the stationary contact of the power supply terminal BAT, the first single-pole single-throw switch S12 is disconnected, the second single-pole double-throw switch S13 contacts the stationary contact of the ground GND, the second single-pole single-throw switch S14 is disconnected, and the boss key control circuit used to control the forward rotation of the seat motor M is turned on.

[0028] like Figure 4 As shown, when the local switch circuit 2 is not in operation, when the switch button corresponding to the boss key switch circuit 1 is pulled down, the first single-pole double-throw switch S11 contacts the stationary contact connected to ground GND, the first single-pole single-throw switch S12 is disconnected, the second single-pole double-throw switch S13 contacts the stationary contact connected to the power supply terminal BAT, the second single-pole single-throw switch S14 is disconnected, and the boss key control circuit used to control the reverse rotation of the seat motor M is turned on.

[0029] like Figure 5 As shown, when the boss key switch circuit 1 is not in operation, the first single-pole double-throw switch S11 and the second single-pole double-throw switch S13 are open, and the first single-pole single-throw switch S12 and the second single-pole single-throw switch S14 are closed. When the switch button corresponding to the local switch circuit 2 is pulled upward, the third single-pole double-throw switch S21 contacts the stationary contact connected to the first single-pole single-throw switch S12, and is connected to the power supply terminal BAT through the first single-pole single-throw switch S12. The fourth single-pole double-throw switch S22 contacts the stationary contact connected to the second single-pole single-throw switch S14, and is connected to ground GND through the second single-pole single-throw switch S14, so that the local control circuit used to control the forward rotation of the seat motor M is closed.

[0030] like Figure 6 As shown, when the boss key switch circuit 1 is not in operation, the first single-pole double-throw switch S11 and the second single-pole double-throw switch S13 are open, and the first single-pole single-throw switch S12 and the second single-pole single-throw switch S14 are closed. When the switch button corresponding to the local switch circuit 2 is pulled down, the third single-pole double-throw switch S21 contacts the stationary contact connected to the second single-pole single-throw switch S14, and is connected to ground GND through the second single-pole single-throw switch S14. The fourth single-pole double-throw switch S22 contacts the stationary contact connected to the first single-pole single-throw switch S12, and is connected to the power supply terminal BAT through the first single-pole single-throw switch S12, so that the local control circuit used to control the reverse rotation of the seat motor M is closed.

[0031] like Figure 7As shown, when the switch buttons corresponding to the boss key switch circuit 1 and the local switch circuit 2 are pulled upwards together, the first single-pole double-throw switch S11 contacts the stationary contact connected to the power supply terminal BAT, the first single-pole double-throw switch S12 is open, the second single-pole double-throw switch S13 contacts the stationary contact connected to ground GND, and the second single-pole single-throw switch S14 is open, thus making the boss key control circuit conductive. Because the first single-pole single-throw switch S12 and the second single-pole single-throw switch S14 are open, the third single-pole double-throw switch S21 and the fourth single-pole double-throw switch S22 cannot form a conductive local control circuit with the seat motor M. That is, when the switch buttons of both switch circuits are pressed simultaneously, only the boss key control circuit is conductive while the local control circuit is open, thus enabling the boss key control circuit to have a higher adjustment priority than the local control circuit.

[0032] In this embodiment, a first linkage branch is formed based on the first single-pole double-throw switch S11 and the second single-pole double-throw switch S13, and a second linkage branch is formed based on the first single-pole single-throw switch S12 and the second single-pole single-throw switch S14. When the first linkage branch and the second linkage branch are linked for control, the boss key control circuit corresponding to the first linkage branch can be turned on, while the local control circuit corresponding to the second linkage branch can be turned off, so that the adjustment priority of the boss key control circuit is higher than the adjustment priority of the local control circuit.

[0033] In one embodiment, the first switch branch 11 includes a first double-pole triple-throw switch S15. The first moving contact of the first double-pole triple-throw switch S15 is connected to the first terminal of the seat motor M, and the second moving contact of the first double-pole triple-throw switch S15 is connected to the first terminal of the seat motor M through the local switch circuit 2. The three stationary contacts of the first double-pole triple-throw switch S15 are respectively connected to the power supply terminal BAT, ground GND, and the power supply terminal BAT. The second switch branch 12 includes a second double-pole triple-throw switch S16. The first moving contact of the second double-pole triple-throw switch S16 is connected to the seat motor M. The second moving contact of the second double-pole triple-throw switch S16 is connected to the second terminal of the chair motor M through the local switch circuit 2. The three stationary contacts of the second double-pole triple-throw switch S16 are respectively connected to ground GND, power supply terminal BAT and ground GND. The first double-pole triple-throw switch S15 and the second double-pole triple-throw switch S16 are linked to control each other so that when one of the third linkage branch formed by the first moving contacts of the two double-pole triple-throw switches and the fourth linkage branch formed by the second moving contacts of the two double-pole triple-throw switches is turned on, the other is turned off.

[0034] As an example, the boss key switch circuit 1 includes a first double-pole triple-throw switch S15 and a second double-pole triple-throw switch S16. The first moving contact of the first double-pole triple-throw switch S15 is connected to the first end of the seat motor M, while the second moving contact is connected to the first end of the seat motor M through a local switch circuit 2. The three stationary contacts are respectively connected to the power supply terminal BAT, ground GND, and power supply terminal BAT. By moving the linkage contact of the first double-pole triple-throw switch S15, the switching state of the first double-pole triple-throw switch S15 is switched. Correspondingly, the first moving contact of the second double-pole triple-throw switch S16 is connected to the second end of the seat motor M, while the second moving contact is connected to the second end of the seat motor M through a local switch circuit 2. The three stationary contacts are respectively connected to ground GND, power supply terminal BAT, and ground GND. By moving the linkage contact of the second double-pole triple-throw switch S16, the switching state of the second double-pole triple-throw switch S16 is switched.

[0035] In this example, the first moving contact of the first double-pole triple-throw switch S15 and the first moving contact of the second double-pole triple-throw switch S16 are respectively connected to the two ends of the seat motor M, and the two stationary contacts are respectively connected to the power supply terminal BAT and ground GND, forming a third linkage branch that can control the operation of the boss key control circuit. The second moving contact of the first double-pole triple-throw switch S15 and the second moving contact of the second double-pole triple-throw switch S16 are respectively connected to the two ends of the seat motor M through the local switch circuit 2, and the two stationary contacts are respectively connected to the power supply terminal BAT and ground GND, forming a fourth linkage branch for controlling the connection of the local switch circuit 2 to the power supply terminal BAT and ground GND.

[0036] In this example, the third linkage branch and the fourth linkage branch are linked and controlled so that when one of them is turned on, the other is turned off. Specifically, it is manifested as follows: (1) When the third linkage branch is turned on and the fourth linkage branch is turned off, either the first moving contact of the first double-pole triple-throw switch S15 and the two first moving contacts of the second double-pole triple-throw switch S16 are connected to the power supply terminal GND, and the other is connected to ground GND, so that the boss key control circuit is turned on, which can control the seat motor M to rotate forward or backward; while the second moving contact of the first double-pole triple-throw switch S15 and the second moving contact of the second double-pole triple-throw switch S16 are not connected to the power supply terminal BAT and ground GND, so that the local control circuit where the local switch circuit 2 is located is turned off. (2) When the third linkage branch is disconnected and the fourth linkage branch is connected, the first moving contact of the first double-pole triple-throw switch S15 and the second double-pole triple-throw switch S16 are not connected to the power supply terminal GND and ground GND, so that the boss key control circuit is disconnected; while either the second moving contact of the first double-pole triple-throw switch S15 and the second moving contact of the second double-pole triple-throw switch S16 is connected to the power supply terminal BAT, and the other is connected to ground GND, so that the local control circuit can be controlled to be connected or disconnected according to the switching state of the local switch circuit 2.

[0037] In this embodiment, a third linkage branch is formed based on the first moving contact of the first double-pole triple-throw switch S15 and the second double-pole triple-throw switch S16 and the two stationary contacts connecting the power supply terminal BAT and ground GND.
