[0020] Figure 2 This is a structural schematic diagram of a seat adjustment device provided in an embodiment of the present utility model. Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] Figure 1 This is a structural block diagram of a seat adjustment device provided in an embodiment of the present invention. Figure 2 This is a structural schematic diagram of a seat adjustment device provided in an embodiment of this utility model. (Reference) Figure 1 and Figure 2 The seat adjustment device includes an adjustment module 10 and a controller 20; wherein the adjustment module 10 includes a resistor unit 12, the resistor unit 12 has at least two effective resistance values ​​during the adjustment process; the range of effective resistance values ​​formed by the resistor unit 12 does not overlap with the range of resistance values ​​of water; the controller 20 adjusts the seat based on the effective resistance values ​​formed by the resistor unit 12.

[0023] Specifically, the adjustment process involves adjusting the seat. During this process, the resistor unit 12 generates at least two effective resistance values, and the controller 20 adjusts the seat based on these effective resistance values. For example, when the adjustment operation involves moving the seat forward in the horizontal direction, the resistor unit 12 generates a corresponding effective resistance value, and the controller 20 adjusts the seat forward in the horizontal direction based on this value. Furthermore, the range of effective resistance values ​​generated by the resistor unit 12 does not overlap with the range of water resistance values. This prevents the controller 20 from mistakenly identifying the water resistance value as the effective resistance value generated by the resistor unit 12 in wet environments, such as when the vehicle containing the seat is submerged, and adjusting the seat accordingly. This solves the problem of incorrect seat adjustment and ensures the reliability of the seat adjustment.

[0024] The seat adjustment device provided in this embodiment includes: an adjustment module, which includes a resistor unit. The resistor unit has at least two effective resistance values ​​during adjustment. The effective resistance value range formed by the resistor unit does not overlap with the resistance value range of water. A controller adjusts the seat based on the effective resistance value formed by the resistor unit. The seat adjustment device provided in this embodiment uses a controller to collect data on the effective resistance value formed by the resistor unit. Furthermore, the effective resistance value range formed by the resistor unit does not overlap with the resistance value range of water. This prevents the controller from mistakenly identifying the water resistance value as the effective resistance value formed by the resistor unit and adjusting the seat based on that value in a wet environment, such as when the vehicle containing the seat is submerged in water. This avoids incorrect seat adjustment and ensures the reliability of the seat adjustment.

[0025] Optionally, the effective resistance value formed by the resistance unit 12 is R2, where 0 ≤ R2 ≤ 700 Ω or R2 ≥ 1400 Ω.

[0026] Specifically, if the resistance value of water is R1, for example, 700 Ω < R1 < 1400 Ω, then the range where the effective resistance value R2 formed by the resistance unit 12 can be 0 - 700 Ω, or the effective resistance value R2 formed by the resistance unit 12 can also be greater than or equal to 1400 Ω, so as to avoid the range of the resistance value of water, and prevent the controller from misidentifying the resistance value of water as the effective resistance value formed by the resistance unit 12 and adjusting the seat according to this resistance value in a water environment such as when the vehicle where the seat is located is flooded, resulting in incorrect adjustment of the seat, effectively avoiding the problem of misidentification by the controller.

[0027] In addition, if A < R1 < B, then set 0 ≤ R2 ≤ A or R2 ≥ B, where A is less than B, to ensure that the range where the effective resistance value R2 formed by the resistance unit 12 has no overlap with the range of the resistance value R1 of water, effectively avoiding the problem of misidentification by the controller.

[0028] Reference Figure 1 and Figure 2 Optionally, the adjustment module 10 further includes a switch unit 11, where: the switch unit 11 has at least two switch states; the resistance unit 12 is connected to the switch unit 11, and the resistance unit 12 forms a corresponding effective resistance value when the switch unit 11 switches to different switch states.

[0029] Exemplarily, the adjustment operations include the operation of the seat adjusting forward and backward in the horizontal direction and the operation of the seat adjusting up and down in the height direction. The operation of the seat adjusting forward and backward in the horizontal direction includes the operation of the seat adjusting forward in the horizontal direction and the operation of the seat adjusting backward in the horizontal direction, and the operation of the seat adjusting up and down in the height direction includes the operation of the seat adjusting up in the height direction and the operation of the seat adjusting down in the height direction. Each operation corresponds to a different switch state. The resistance unit 12 is electrically connected to the switch unit 11. When the switch unit 11 switches to the corresponding switch state in response to the adjustment operation, the resistance unit 12 forms a corresponding effective resistance value, and the effective resistance value formed by the resistance unit 12 in each switch state is different, so as to ensure that the controller 20 adjusts the seat to match the adjustment operation corresponding to the switch state according to the effective resistance value formed by the resistance unit 12 corresponding to the switch state.

[0030] In addition, the controller 20 can adjust the seat by collecting the effective resistance value formed by the resistance unit 12. The way for the controller 20 to collect the effective resistance value formed by the resistance unit 12 can be to collect current and voltage, which is not limited herein.

[0031] Optionally, the resistor unit 12 includes at least two resistors connected in series. When the switch unit 11 switches to different switch states, it selects different numbers of resistors connected in series to form corresponding effective resistance values.

[0032] For example, there are two switching units 11 and two resistor units 12. Each resistor unit 12 includes four resistors connected in series, and each switching unit 11 includes four switching states. When the switching unit 11 switches to one of the four different switching states, the resistor unit 12 selects four different numbers of resistors connected in series. The four switching states of one switching unit 11 correspond one-to-one with the four different numbers of resistors selected in series by one resistor unit 12, and the four switching states of the other switching unit 11 correspond one-to-one with the four different numbers of resistors selected in series by the other resistor unit 12. For example, when the switching unit 11 switches to one switching state, the corresponding resistor unit 12 selects four resistors in series in that resistor unit 12; when the switching unit 11 switches to another switching state, the corresponding resistor unit 12 selects three resistors in series in that resistor unit 12; and when the switching unit 11 switches to yet another switching state, the corresponding resistor unit 12 selects two resistors in series in that resistor unit 12, thereby forming effective resistance values ​​corresponding to different switching states.

[0033] Optionally, each switching unit 11 includes at least two switching states. The switching unit 11 is a single-pole multi-throw switch, and the number of switching positions of the switching unit is the same as the number of switching states.

[0034] For example, there are two switch units 11, each switch unit 11 includes four switch states, each switch unit 11 is a single-pole four-throw switch, the number of switch positions of switch unit 11 is four, the number of switch states is the same as the number of switch positions, and the number of switch states is also four, thereby ensuring the matching of switch positions and switch states of switch unit 11.

[0035] Furthermore, a single-pole multi-throw (SPMD) switch is a switch with one common terminal (moving terminal) and multiple output terminals (fixed terminals). The common terminal can be connected to any one of the multiple output terminals to achieve the switching function. In this SPMD switch, "single-pole" indicates that there is only one movable connecting part, i.e., the moving terminal; "multi-throw" indicates that the moving terminal can be connected to multiple different fixed terminals, i.e., multiple different output terminals, providing multiple throw options. SPMD switches include mechanical SPMD switches and electronic SPMD switches. Mechanical SPMD switches achieve switching by manually operating mechanical components. Mechanical SPMD switches have a simple structure, low cost, high reliability, and can withstand large currents and voltages. Electronic SPMD switches are based on electronic components such as diodes, transistors, and field-effect transistors. They achieve switching on and off through control signals, featuring fast response speed, high switching accuracy, easy integration, and remote control capabilities. The specific type of SPMD switch in this embodiment can be determined according to the actual adjustment requirements of the seat adjustment device and is not limited here.

[0036] Optionally, the switching unit 11 is used to respond to at least one adjustment operation, which is an operation to adjust the posture of the seat in at least one dimension.

[0037] Specifically, the adjustment operation includes adjusting the seat to move back and forth in the horizontal direction and adjusting the seat to move up and down in the vertical direction. The switch unit 11 responds to the adjustment operation by responding to the seat to move back and forth in the horizontal direction and to adjusting the seat to move up and down in the vertical direction, so as to ensure that the switch unit 11 can respond to the posture adjustment operation of the seat in at least one dimension.

[0038] refer to Figure 1 and Figure 2 Optionally, the number of switch units 11 is two; the switch unit 11 includes a first switch unit 111 and a second switch unit 112. The first switch unit 111 is used to respond to the adjustment operation of moving the seat back forward and backward in the horizontal direction and the adjustment operation of moving the seat up and down in the vertical direction; the second switch unit 112 is used to respond to the adjustment operation of moving the seat back tilt and the adjustment operation of moving the seat cushion tilt.

[0039] Specifically, the adjustment operations for moving the seat forward and backward in the horizontal direction include forward adjustment and backward adjustment in the horizontal direction; the adjustment operations for moving the seat up and down in the vertical direction include upward adjustment and downward adjustment in the vertical direction. The first switch unit 111 responds to the forward adjustment, backward adjustment, upward adjustment, and downward adjustment operations in the horizontal direction. The adjustment operations for tilting the seat back include forward tilting and backward tilting; the adjustment operations for tilting the seat cushion include upward tilting and downward tilting of the front end of the seat cushion. The second switch unit 112 responds to adjustment operations such as tilting the seat back forward, tilting the seat back backward, tilting the front end of the seat cushion upward, and tilting the front end of the seat cushion downward, thereby enabling the first switch unit 111 and the second switch unit 112 to respond to adjustment operations that require various movements of the seat.

[0040] Optionally, the first switch unit 111 is a single-pole four-throw switch, and the second switch unit 112 is two single-pole double-throw switches, one of which is used to respond to the adjustment operation of the backrest tilt movement of the seat, and the other is used to respond to the adjustment operation of the seat cushion tilt movement.

[0041] For details, please refer to Figure 1 and Figure 2Resistor unit 12 includes a first resistor unit 121 and a second resistor unit 122. The first resistor unit 121 includes a first resistor, a second resistor, a third resistor, and a fourth resistor connected in series. The second resistor unit 122 includes a fifth resistor, a sixth resistor, a seventh resistor, and an eighth resistor connected in series. The first terminal of the first resistor is electrically connected to the controller; the second terminal of the first resistor is electrically connected to the first terminal of the second resistor; the second terminal of the second resistor is electrically connected to the first terminal of the third resistor; the second terminal of the third resistor is electrically connected to the first terminal of the fourth resistor; the second terminal of the first resistor is electrically connected to the first output terminal of the single-pole four-throw switch (first switch unit 111); the second terminal of the second resistor is electrically connected to the second output terminal of the single-pole four-throw switch; the second terminal of the third resistor is electrically connected to the third output terminal of the single-pole four-throw switch; the second terminal of the fourth resistor is electrically connected to the fourth output terminal of the single-pole four-throw switch; and the common terminal of the single-pole four-throw switch is grounded (GND). A single-pole four-throw switch is used to respond to adjustment operations of moving the seat back and forth in the horizontal direction and adjustment operations of moving the seat up and down in the vertical direction. When the adjustment operation is either the adjustment operation of moving the seat back and forth in the horizontal direction or the adjustment operation of moving the seat up and down in the vertical direction, the common terminal of the single-pole four-throw switch is electrically connected to its first output terminal, or the common terminal of the single-pole four-throw switch is electrically connected to its second output terminal, or the common terminal of the single-pole four-throw switch is electrically connected to its third output terminal, or the common terminal of the single-pole four-throw switch is electrically connected to its fourth output terminal.

[0042] For example, when the adjustment operation is to move the seat forward in the horizontal direction, the common terminal of the single-pole four-throw switch is electrically connected to its first output terminal, and the effective resistance value collected by the controller is the resistance value of the first resistor; when the adjustment operation is to move the seat backward in the horizontal direction, the common terminal of the single-pole four-throw switch is electrically connected to its second output terminal, and the effective resistance value collected by the controller is the total resistance value of the first resistor and the second resistor in series; when the adjustment operation is to move the seat upward in the vertical direction, the common terminal of the single-pole four-throw switch is electrically connected to its third output terminal, and the effective resistance value collected by the controller is the total resistance value of the first resistor, the second resistor, and the third resistor in series; when the adjustment operation is to move the seat downward in the vertical direction, the common terminal of the single-pole four-throw switch is electrically connected to its fourth output terminal, and the effective resistance value collected by the controller is the total resistance value of the first resistor, the second resistor, the third resistor, and the fourth resistor in series. This allows the controller to adjust the seat according to the collected effective resistance value, such as by controlling a motor electrically connected to the controller for adjusting the seat. The specific process of the controller adjusting the seat via the motor can be found in existing technology and will not be described in detail here.

[0043] Furthermore, the first end of the fifth resistor is electrically connected to the controller, the second end of the fifth resistor is electrically connected to the first end of the sixth resistor, the second end of the sixth resistor is electrically connected to the first end of the seventh resistor, and the second end of the seventh resistor is electrically connected to the first end of the eighth resistor; the second end of the fifth resistor is electrically connected to the first output terminal of the first single-pole double-throw switch in the second switch unit 112 (the two single-pole double-throw switches are the first single-pole double-throw switch and the second single-pole double-throw switch), the second end of the sixth resistor is electrically connected to the second output terminal of the first single-pole double-throw switch, the second end of the seventh resistor is electrically connected to the first output terminal of the second single-pole double-throw switch, and the second end of the eighth resistor is electrically connected to the second output terminal of the second single-pole double-throw switch; the common terminal of each single-pole double-throw switch is grounded. The first single-pole double-throw switch is used to respond to the adjustment operation of tilting the seat back, and the second single-pole double-throw switch is used to respond to the adjustment operation of tilting the seat cushion. When the adjustment operation is either the adjustment operation of tilting the seat back or the adjustment operation of tilting the seat cushion, the common terminal of the first single-pole double-throw switch is electrically connected to its first output terminal, or the common terminal of the first single-pole double-throw switch is electrically connected to its second output terminal, or the common terminal of the second single-pole double-throw switch is electrically connected to its first output terminal, or the common terminal of the second single-pole double-throw switch is electrically connected to its second output terminal.

[0044] For example, when the adjustment operation is to tilt the seat back forward, the common terminal of the first single-pole double-throw switch is electrically connected to the first output terminal of the first single-pole double-throw switch, and the effective resistance value collected by the controller is the resistance value of the fifth resistor; when the adjustment operation is to tilt the seat back backward, the common terminal of the first single-pole double-throw switch is electrically connected to the second output terminal of the first single-pole double-throw switch, and the effective resistance value collected by the controller is the total resistance value of the fifth resistor and the sixth resistor in series; when the adjustment operation is to tilt the front end of the seat cushion upward, the common terminal of the second single-pole double-throw switch is electrically connected to the first output terminal of the second single-pole double-throw switch, and the effective resistance value collected by the controller is the total resistance value of the fifth resistor, the sixth resistor, the seventh resistor, and the eighth resistor in series, thereby enabling the controller to adjust the seat according to the collected effective resistance values.

Specifically, the first resistor unit 121 includes a first resistor, a second resistor, a third resistor, and a fourth resistor connected in series, and the second resistor unit 122 includes a fifth resistor, a sixth resistor, a seventh resistor, and an eighth resistor connected in series. The first end of the first resistor is electrically connected to the controller, and the connection method between the resistors is the same as described above, and will not be repeated here. The second terminals of the first and second resistors are electrically connected to the first and second output terminals of a single-pole double-throw switch in the first switching unit 111, respectively. The second terminals of the third and fourth resistors are electrically connected to the first and second output terminals of another single-pole four-throw switch in the first switching unit 111, respectively. The common terminal of each single-pole double-throw switch is grounded. The second terminals of the fifth, sixth, seventh, and eighth resistors are electrically connected to the first, second, third, and fourth output terminals of a single-pole four-throw switch in the second switching unit 112, respectively. The common terminal of the single-pole four-throw switch is grounded.

[0046] When the first switching unit 111 responds to an adjustment operation, the common terminal of the single-pole double-throw switch responding to the adjustment operation is electrically connected to its first output terminal, or the common terminal of the single-pole double-throw switch responding to the adjustment operation is electrically connected to its second output terminal. The effective resistance value collected by the controller is the resistance value of the first resistor, or the total resistance value of the first and second resistors in series, or the total resistance value of the first, second, and third resistors in series, or the total resistance value of the first, second, third, and fourth resistors in series. When the second switching unit 112 responds to an adjustment operation, the common terminal of the single-pole four-throw switch of the second switching unit 112 is electrically connected to one of its four output terminals. The effective resistance value collected by the controller is the resistance value of the fifth resistor, or the total resistance value of the fifth and sixth resistors in series, or the total resistance value of the fifth, sixth, and seventh resistors in series, or the total resistance value of the fifth, sixth, seventh, and eighth resistors in series.

[0047] In another embodiment, both the first switching unit 111 and the second switching unit 112 are two single-pole double-throw switches. The two single-pole double-throw switches in the first switching unit 111 are respectively used to respond to adjustment operations of the seat moving back and forth in the horizontal direction and adjustment operations of the seat moving up and down in the vertical direction. The two single-pole double-throw switches in the second switching unit 112 are respectively used to respond to adjustment operations of the seat back tilting and adjustment operations of the seat cushion tilting. Alternatively, both the first switching unit 111 and the second switching unit 112 are single-pole four-throw switches. The single-pole four-throw switch in the first switching unit 111 is used to respond to adjustment operations of the seat moving back and forth in the horizontal direction and adjustment operations of the seat moving up and down in the vertical direction.

Specifically, the first resistor unit 121 includes a first resistor, a second resistor, a third resistor, and a fourth resistor connected in series, and the second resistor unit 122 includes a fifth resistor, a sixth resistor, a seventh resistor, and an eighth resistor connected in series. The first end of the first resistor is electrically connected to the controller. The connection method between each resistor is the same as the above description of the connection method between each resistor, and will not be repeated here.

[0048] When both the first switching unit 111 and the second switching unit 112 are two single-pole double-throw switches, the second ends of the first resistor and the second resistor are electrically connected to the first and second output terminals of one single-pole double-throw switch of the first switching unit 111, respectively. The second ends of the third resistor and the fourth resistor are electrically connected to the first and second output terminals of the other single-pole double-throw switch of the first switching unit 111, respectively. The second ends of the fifth resistor and the sixth resistor are electrically connected to the first and second output terminals of one single-pole double-throw switch of the second switching unit 112, respectively. The second ends of the seventh resistor and the eighth resistor are electrically connected to the first and second output terminals of the other single-pole double-throw switch of the second switching unit 112, respectively. The common terminal of each single-pole double-throw switch is grounded.

The controller collects the effective resistance value formed by the resistor unit 12.
