[0024] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings.

[0025] It should be noted that the terms "first", "second", and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0026] The switch circuit, chip, seat and vehicle of the embodiments of the present application will be described below with reference to the drawings.

[0027] Figure 1 is a schematic diagram of the switch circuit according to an embodiment of the present application.

[0028] As shown in Figure 1 the switch circuit 100 of the embodiments of the present application includes a power supply 110, at least two switch modules (such as a first switch module 101, a second switch module 102, …, an nth switch module 10n) and a motor 120.

[0029] At least two switch modules (such as the first switch module 101, the second switch module 102,..., and the nth switch module 10n) are connected in parallel between the power output end of the power supply 110 and the power input end of the motor 120; each switch module 10i (i is any one of 1-n) has the ability to operate independently, and is used to selectively turn on or turn off the path between the power output end of the power supply 110 and the power input end of the motor 120, to control the working state of the motor 120; wherein, at the same time point, in the case that multiple switch modules (such as the first switch module 101, the second switch module 102,..., and the nth switch module 10n) simultaneously act, the switch module with the highest priority among the multiple switch modules that simultaneously act will successfully turn on the path between the power output end of the power supply 110 and the power input end of the motor 120, and the switch modules with other priorities among the multiple switch modules that simultaneously act will fail to turn on the path between the power output end of the power supply 110 and the power input end of the motor 120.

[0030] It is assumed that the switch circuit 100 of the embodiment of the present application is applied in a seat, such as a seat of a vehicle.

[0031] The at least two switch modules include three switch modules for controlling the movement of the front passenger seat, such as the first switch module 101, the second switch module 102, and the third switch module 103. The first switch module 101, the second switch module 102, and the third switch module 103 are connected in parallel between the power output end of the power supply 110 and the power input end of the motor 120, and selectively turn on or turn off the path between the power output end of the power supply 110 and the power input end of the motor 120 according to a predetermined priority rule, to control the working state of the motor.

[0032] The first switch module 101 is located on the front passenger seat body and is used by the passenger sitting in the front passenger position; the second switch module 102 is arranged behind the back of the front passenger seat and is used by the rear passenger; and the third switch module 103 is arranged in the master control center (such as the central control console) and is used by the driver or other front passenger.

[0033] In order to ensure the rationality of the operation, each switch module has different priorities according to its position and purpose:

[0034] The second switch module 102 has the highest priority, ensuring that the needs of the rear passenger are preferentially met;

[0035] The third switch module 103 has the second priority and is mainly used for global monitoring and management;

[0036] The first switch module 101 has the lowest priority and is used for the operation of the passenger currently sitting in the front passenger seat.

[0037] When the first switch module 101, the second switch module 102 and the third switch module 103 attempt to operate at the same time, only the second switch module 102 with the highest priority can successfully turn on the path between the power output end of the power supply 110 to the power input end of the motor 120 and control the motor to work, while the first switch module 101 and the third switch module 103 will not be able to turn on the path between the power output end of the power supply 110 to the power input end of the motor 120.

[0038] Specific application scenarios:

[0039] Scenario one: the passenger in the front passenger seat wants to move the seat backward through the first switch module 101, while the rear passenger also tries to move the front passenger seat forward through the second switch module 102. Since the second switch module 102 has the highest priority, it will successfully turn on the path between the power output end of the power supply 110 to the power input end of the motor 120, and the motor 120 will first respond to the request of the rear passenger, that is, the motor 120 will move the front passenger seat forward.

[0040] Scenario two: the driver wants to move the position of the front passenger seat backward through the third switch module 103, but the rear passenger also tries to move the front passenger seat forward at the same time through the second switch module 102. At this time, the second switch module 102 still has the highest priority, so the motor 120 responds to the operation of the rear passenger rather than the driver, that is, the motor 120 moves the front passenger seat forward.

[0041] Scenario three: if the driver wants to move the position of the front passenger seat backward through the third switch module 103, but the passenger in the front passenger seat wants to move the position of the front passenger seat forward through the first switch module 101, since the priority of the third switch module 103 is higher than that of the first switch module 101, the motor 120 will respond to the operation of the driver first, that is, the motor 120 will move the front passenger seat backward.

[0042] The switch circuit of the embodiments of the present application not only improves the flexibility and convenience of the seat, but also ensures that the operation needs of key users are prioritized, enhancing user experience and overall reliability of the system. This priority-based control method is particularly suitable for complex environments that require frequent adjustments by multiple users, such as individualized seat position needs of different passengers inside a vehicle.

[0043] The following will be described taking at least two switch modules including the first switch module 101 and the second switch module 102 as an example.

[0044] As Figures 2-9As shown, the first switch module 101 comprises: a first switch K1, a second switch K2, a third switch K3, a fourth switch K4 and a first switch unit; wherein,

[0045] The first switch K1 comprises a first stationary contact 1, a second stationary contact 2, a third stationary contact 3 and a first movable contact a;

[0046] The second switch K2 comprises a fourth stationary contact 4, a fifth stationary contact 5, a sixth stationary contact 6 and a second movable contact b;

[0047] The third switch K3 comprises a seventh stationary contact 7, an eighth stationary contact 8, a ninth stationary contact 9 and a third movable contact c;

[0048] The fourth switch K4 comprises a tenth stationary contact 10, an eleventh stationary contact 11, a twelfth stationary contact 12 and a fourth movable contact d;

[0049] The first stationary contact 1, the third stationary contact 3, the tenth stationary contact 10 and the twelfth stationary contact 12 are suspended;

[0050] The second stationary contact 2, the sixth stationary contact 6 and the seventh stationary contact 7 are respectively connected with a first electrode of a power supply 110;

[0051] The fourth stationary contact 4, the ninth stationary contact 9 and the eleventh stationary contact 11 are respectively connected with a second electrode of the power supply;

[0052] The first movable contact a is connected with a second switch module 102;

[0053] The second movable contact b is respectively connected with a first end of a motor 120 and the second switch module 102;

[0054] The third movable contact c is respectively connected with a second end of the motor 120 and the second switch module 102;

[0055] The fourth movable contact d is connected with the second switch module 102;

[0056] The first switch unit is used for synchronously controlling states of the first switch K1, the second switch K2, the third switch K3 and the fourth switch K4.

[0057] As shown in the figure, Figures 2-9 The second switch module 102 comprises: a fifth switch K5, a sixth switch K6 and a second switch unit; wherein,

[0058] The fifth switch K5 comprises a thirteenth stationary contact 13, a fourteenth stationary contact 14, a fifteenth stationary contact 15 and a fifth movable contact e;

[0059] The sixth switch K6 comprises a sixteenth stationary contact 16, a seventeenth stationary contact 17, an eighteenth stationary contact 18 and a sixth movable contact f;

[0060] The fourteenth stationary contact 14 and the seventeenth stationary contact 17 are suspended;

[0061] The first moving contact a is connected to the fifteenth stationary contact 15 and the sixteenth stationary contact 16 respectively;

[0062] The second moving contact b is connected to the first end of the motor 120 and the fifth moving contact e, respectively.

[0063] The third moving contact c is connected to the second terminal of motor 120 and the sixth moving contact f, respectively.

[0064] The fourth moving contact d is connected to the thirteenth stationary contact 13 and the eighteenth stationary contact 18, respectively;

[0065] The second switching unit is used to synchronously control the states of the fifth switch K5 and the sixth switch K6.

[0066] In one embodiment of this application, the first switch unit and the second switch unit are switch buttons.

[0067] like Figure 2 As shown, when the first switch unit controls the first moving contact a to connect with the second stationary contact 2, the second moving contact b to connect with the fifth stationary contact 5, the third moving contact c to connect with the eighth stationary contact 8, and the fourth moving contact d to connect with the eleventh stationary contact 11, and the second switch unit controls the fifth moving contact e to connect with the fourteenth stationary contact 14, and the sixth moving contact f to connect with the seventeenth stationary contact 17, both the first switch module 101 and the second switch module 102 are used to disconnect the path between the power output terminal of the power supply 110 and the power input terminal of the motor 120, and the working state of the motor 120 is in the state of non-adjusting load movement.

[0068] In other words, when the user does not perform any action, the first switch K1, the second switch K2, the third switch K3, the fourth switch K4, the fifth switch K5, and the sixth switch K6 are all in the middle position. At this time, no current flows through the motor, and it is in an unadjusted state.

[0069] The following explanation uses the seat as the load and the seat level adjustment as an example.

[0070] like Figure 3 and Figure 4As shown, when the first switch unit controls the first moving contact a to be connected with the third stationary contact 3, the second moving contact b to be connected with the sixth stationary contact 6, the third moving contact c to be connected with the ninth stationary contact 9, the fourth moving contact d to be connected with the twelfth stationary contact 12, and the second switch unit controls the fifth moving contact e to be connected with any one of the thirteenth stationary contact 13, the fourteenth stationary contact 14 and the fifteenth stationary contact 15, and the sixth moving contact f to be connected with any one of the sixteenth stationary contact 16, the seventeenth stationary contact 17 and the eighteenth stationary contact 18, the first switch unit turns on the path between the power output end of the power supply 110 and the power input end of the motor 120, and the working state of the motor 120 is in the control of the load moving in the first direction.

[0071] As shown in FIG. 1, the first switch unit is not dials, and the second switch unit is dials, at this time, the whole switch circuit 100 is as follows: the positive pole of the power supply is connected with the third moving contact c of the third switch K3 through the ninth stationary contact 9 of the third switch K3, and then connected with the M+ of the motor 120 through the wire harness, and then connected with the second moving contact b of the second switch K2 through the wire harness, and then connected with the sixth stationary contact 6 of the second switch K2, and then connected with the negative pole of the whole vehicle power supply. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from + to -), which represents the seat horizontally adjusting forward, at this time, it represents that the seat has been adjusted to move horizontally forward by the first switch module 101. Figure 3 As shown in FIG. 1, the first switch unit is not dials, and the second switch unit is dials, at this time, the whole switch circuit 100 is as follows: the positive pole of the power supply is connected with the third moving contact c of the third switch K3 through the ninth stationary contact 9 of the third switch K3, and then connected with the M+ of the motor 120 through the wire harness, and then connected with the second moving contact b of the second switch K2 through the wire harness, and then connected with the sixth stationary contact 6 of the second switch K2, and then connected with the negative pole of the whole vehicle power supply. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from + to -), which represents the seat horizontally adjusting forward, at this time, it represents that the seat has been adjusted to move horizontally forward by the first switch module 101.

[0072] Figure 4 As shown in FIG. 1, the first switch unit is not dials, and the second switch unit is dials, at this time, the whole switch circuit 100 is as follows: the positive pole of the power supply is connected with the third moving contact c of the third switch K3 through the ninth stationary contact 9 of the third switch K3, and then connected with the M+ of the motor 120 through the wire harness, and then connected with the second moving contact b of the second switch K2 through the wire harness, and then connected with the sixth stationary contact 6 of the second switch K2, and then connected with the negative pole of the whole vehicle power supply. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from + to -), which represents the seat horizontally adjusting forward, at this time, it represents that the seat has been adjusted to move horizontally forward by the first switch module 101.

[0073] As shown in FIG. 1, the first switch unit is not dials, and the second switch unit is dials, at this time, the whole switch circuit 100 is as follows: the positive pole of the power supply is connected with the third moving contact c of the third switch K3 through the ninth stationary contact 9 of the third switch K3, and then connected with the M+ of the motor 120 through the wire harness, and then connected with the second moving contact b of the second switch K2 through the wire harness, and then connected with the sixth stationary contact 6 of the second switch K2, and then connected with the negative pole of the whole vehicle power supply. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from + to -), which represents the seat horizontally adjusting forward, at this time, it represents that the seat has been adjusted to move horizontally forward by the first switch module 101.

[0074] As shown in FIG. 1, the first switch unit is not dials, and the second switch unit is dials, at this time, the whole switch circuit 100 is as follows: the positive pole of the power supply is connected with the third moving contact c of the third switch K3 through the ninth stationary contact 9 of the third switch K3, and then connected with the M+ of the motor 120 through the wire harness, and then connected with the second moving contact b of the second switch K2 through the wire harness, and then connected with the sixth stationary contact 6 of the second switch K2, and then connected with the negative pole of the whole vehicle power supply. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from + to -), which represents the seat horizontally adjusting forward, at this time, it represents that the seat has been adjusted to move horizontally forward by the first switch module 101. Figure 5 , Figure 6 , Figure 7 ​As shown, when the first switch unit controls the first moving contact a to be connected with the first stationary contact 1, the second moving contact b to be connected with the fourth stationary contact 4, the third moving contact c to be connected with the seventh stationary contact 7, and the fourth moving contact d to be connected with the tenth stationary contact 10, and the second switch unit controls the fifth moving contact e to be connected with any one of the thirteenth stationary contact 13, the fourteenth stationary contact 14 and the fifteenth stationary contact 15, and the sixth moving contact f to be connected with any one of the sixteenth stationary contact 16, the seventeenth stationary contact 17 and the eighteenth stationary contact 18, the first switch unit turns on the path between the power output end of the power supply 110 and the power input end of the motor 120, and the working state of the motor 120 is in the control of the load moving to the second direction.

[0075] As shown in FIG. 6, when the first switch unit is not dials to the left, and the second switch unit is dials to the right, the whole switch circuit 100 is in the state of the positive pole of the power supply 110 being connected with the second moving contact b of the second switch K2 through the fourth stationary contact 4 of the second switch K2, and then being connected with the M- of the motor 120 through the wire harness, and then being connected with the third moving contact c of the third switch K3 through the wire harness, and then being connected with the seventh stationary contact 7 of the third switch K3, and then being connected with the negative pole of the power supply 110. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from M+ to M-), it represents that the seat is adjusted to move horizontally forward, and at this time, the current flows in the opposite direction, which represents that the seat is adjusted to move horizontally backward through the first switch unit. Figure 5 As shown in FIG. 7, when the first switch unit and the second switch unit are both dials to the left, the circuit through the fifth switch K5 and the sixth switch K6 does not form a loop, and the effect is equivalent to that the first switch unit is dials to the left alone, and the priority of the two switches can be distinguished, and the priority of the first switch module 101 is greater than that of the second switch module 102.

[0076] Figure 6 As shown in FIG. 8, when the first switch unit is dials to the left, and the second switch unit is dials to the right, the circuit through the fifth switch K5 and the sixth switch K6 does not form a loop, and the effect is equivalent to that the first switch unit is dials to the left alone, and the priority of the two switches can be distinguished, and the priority of the first switch module 101 is greater than that of the second switch module 102.

[0077] As shown in FIG. 9, when the first switch unit is dials to the left, and the second switch unit is dials to the right, the circuit through the fifth switch K5 and the sixth switch K6 does not form a loop, and the effect is equivalent to that the first switch unit is dials to the left alone, and the priority of the two switches can be distinguished, and the priority of the first switch module 101 is greater than that of the second switch module 102. Figure 7 As shown in FIG. 10, when the first switch unit is dials to the left, and the second switch unit is dials to the right, the circuit through the fifth switch K5 and the sixth switch K6 does not form a loop, and the effect is equivalent to that the first switch unit is dials to the left alone, and the priority of the two switches can be distinguished, and the priority of the first switch module 101 is greater than that of the second switch module 102.

[0078] Figure 8 ​​As shown, when the first switch unit controls the first moving contact a to connect with the second stationary contact 2, the second moving contact b to connect with the fifth stationary contact 5, the third moving contact c to connect with the eighth stationary contact 8, the fourth moving contact d to connect with the eleventh stationary contact 11, and the second switch unit controls the fifth moving contact e to connect with the thirteenth stationary contact 13, the sixth moving contact f to connect with the sixteenth stationary contact 16, the second switch module 102 conducts the path between the power output end of the power supply 110 and the power input end of the motor 120, and the working state of the motor 120 is in the control of the load moving to the second direction.

[0079] That is, when the second switch unit is dials to the right side and the first switch unit is not dialled, the whole switch circuit 100 is as follows: the positive pole of the power supply 110 is connected to the fourth moving contact d of the fourth switch K4 through the eleventh stationary contact 11 of the fourth switch K4, and then connected to the sixteenth stationary contact 16 of the sixth switch K6 through the wire harness, the sixteenth stationary contact 18 of the sixth switch K6 is connected to the sixth moving contact f of the sixth switch K6, and then connected to M+ of the motor 120, and then connected to the fifth moving contact e of the fifth switch K5 through the wire harness from M- of the motor 120, the fifth moving contact e of the fifth switch K5 is connected to the fifteenth stationary contact 15 of the fifth switch K5, the fifteenth stationary contact 15 of the fifth switch K5 is connected to the first moving contact a of the first switch K1, the first moving contact a of the first switch K1 is connected to the second stationary contact 2 of the first switch K1, and the second stationary contact 2 of the first switch K1 is connected to the negative pole of the whole vehicle power supply 110. Assuming that the motor 120 rotates in the positive direction (i.e. the current flows from M+ to M-), it represents the seat horizontally adjusting forward, and at this time it represents that the seat is adjusted to move horizontally forward through the second switch module 102.

[0080] As shown, Figure 9 As shown, when the first switch unit controls the first moving contact a to connect with the second stationary contact 2, the second moving contact b to connect with the fifth stationary contact 5, the third moving contact c to connect with the eighth stationary contact 8, the fourth moving contact d to connect with the eleventh stationary contact 11, and the second switch unit controls the fifth moving contact e to connect with the thirteenth stationary contact 13, the sixth moving contact f to connect with the sixteenth stationary contact 16, the second switch module 102 conducts the path between the power output end of the power supply 110 and the power input end of the motor 120, and the working state of the motor 120 is in the control of the load moving to the second direction.
