In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] In related technologies, seat position adjustment is achieved through a corresponding seat adjustment module. The switches used inside are standard modular switches, and the user operates the seat adjustment module by the deformation of a spring. However, the spring generates a relatively loud sound during deformation, resulting in significant noise when the user needs to adjust the seat position, thus affecting the user's experience.

[0025] The button 210 of this application is made of silicone or rubber. When the button 210 is deformed, the noise generated by the button 210 is small, which can improve the user experience to a certain extent.

[0026] This application provides a vehicle, which includes a vehicle body and seat assemblies, with the seat assemblies installed on the vehicle body. For example, the vehicle may be a car, and the seat assemblies are installed inside the vehicle body. There may be multiple seat assemblies, spaced apart from each other on the vehicle body.

[0027] This application embodiment also provides a seat assembly, which includes a seat body, a circuit board, and a switching device. The circuit board is mounted on the seat body, and the switching device is mounted on the seat body. The switching device can electrically connect the circuit board to adjust the position of the seat body. Exemplarily, the seat assembly also includes a drive device, which is electrically connected to the circuit board. When the circuit board is connected, the drive device can drive the seat body to move relative to the vehicle body.

[0028] This application provides a switching device; please refer to [link / reference]. Figures 1 to 3The switching device includes a drive mechanism 100 and a button 200. The drive mechanism 100 includes a lever assembly 110 and a push rod 120, the lever assembly 110 being able to abut against the push rod 120. The button 200 is mounted on the drive mechanism 100, and the button 200 and the drive mechanism 100 are arranged along a first direction, with a button cover disposed on one end of the drive mechanism 100. Exemplarily, the first direction is parallel to the thickness direction of the switching device. The push rod 120 is able to approach the drive mechanism 100 along the first direction under the drive of the lever assembly 110. The button 200 includes a button 210 and a button body connected to each other, the button 210 being able to move relative to the button body along the first direction, and the button body being generally plate-shaped. Exemplarily, the button 200 is a one-piece molded structure. The button 210 is able to move relative to the button body along the first direction under the push of the push rod 120, and the button 210 is used to abut against a circuit board. When the button 210 abuts against the circuit board, the circuit board is electrically connected. The button 210 is made of silicone or rubber. For example, the button 210 has conductive terminals inside. When the button 210 abuts against the circuit board, the circuitry of the circuit board can be electrically connected through the conductive terminals, thereby allowing the overall position of the seat to change, such as in the first direction. Figure 3 The direction indicated by the middle arrow R1.

[0029] In this embodiment of the application, the switch device, via the drive mechanism 100, can drive the button 200 to move toward the circuit board in a first direction. When the button 200 abuts against the circuit board, the corresponding circuit on the circuit board is switched to a closed circuit, thereby changing the position of the corresponding seat. The button 210 is made of silicone or rubber, resulting in less noise between the button 210 and the circuit board, thus improving the user experience. Furthermore, the button 210 can continue to elastically deform when it abuts against the circuit board, thereby reducing the possibility of the button 210 causing damage to the circuit board, and the switch device can better adapt to various movement strokes.

[0030] In one embodiment, please refer to Figures 3 to 5 The button component 200 is detachably connected to the drive mechanism 100. The button component 200 can be manufactured in various specifications according to actual needs. For example, the size of the button 210 along the first direction can be adjusted according to actual needs, thereby adjusting the distance between the button 210 and the circuit board and the push rod 120 along the first direction, thus allowing the switching device to better adapt to various travel distances. Switching devices with multiple travel distances can share the same drive mechanism 100, resulting in a high degree of adaptability of the switching device.

[0031] It is understood that other embodiments of this application are not limited to the button 200 and the drive mechanism 100 being detachably connected. Exemplarily, the button 200 and part of the drive mechanism 100 are integrally formed.

[0032] In one embodiment, please refer to Figure 3 and Figure 4 The drive mechanism 100 further includes a housing 130 and a bracket 140. The button 200 is mounted on the housing 130, the push rod 120 is movably mounted on the housing 130, and the bracket 140 is rotatably mounted on the housing 130. Both the housing 130 and the bracket 140 abut against the lever assembly 110 and are movable relative to the housing 130 along a second direction. This second direction is orthogonal to the first direction. The second direction is as follows: Figure 3 The direction indicated by the middle arrow R2. For example, the bracket 140 is rotatable relative to the housing 130 along a first axis of rotation. The extension direction of the first axis of rotation is orthogonal to both the first and second directions. The extension direction of the first axis of rotation is a third direction, such as... Figure 4 The first axis of rotation is as shown by the middle arrow R3. Figure 3 As shown by the dashed line O. When the lever assembly 110 moves along the second direction, the bracket 140 can rotate relative to the housing 130 under the drive of the lever assembly 110. The bracket 140 can abut against the push rod 120 and push the push rod 120 to move along the first direction. The bracket 140 can rotate relative to the housing 130, while both the lever assembly 110 and the push rod 120 can move relative to the housing 130. When the lever assembly 110 moves relative to the housing 130 along the second direction, the lever assembly 110 can push the bracket 140 to rotate. When the bracket 140 rotates, the bracket 140 deflects along the first direction. The bracket 140 can push the push rod 120 located below to move along the first direction, thereby causing the push rod 120 to press against the button 210 and push the button 210 towards the circuit board. The housing 130 and the bracket 140 are separate structures. When the switch device needs maintenance, the damaged components can be replaced separately. For example, the button 200 has a positioning hole that extends through the button 200 in a first direction, and the housing 130 has a positioning part that can cooperate with the positioning hole. The positioning part protrudes from the housing 130 in the first direction. When the button 200 is installed in the housing 130, the positioning part extends through the positioning hole. The positioning hole and the positioning part can limit the displacement of the button 200 in other directions to a certain extent.

[0033] In one embodiment, please refer to Figures 3 to 5The drive mechanism 100 further includes a top cover 150 mounted on the housing 130. Along the first direction, the top cover 150 is located on the side of the housing 130 opposite to the button 200. The top cover 150 has a limiting hole 150a extending along the second direction. The lever assembly 110 passes through the limiting hole 150a and protrudes from the top cover 150 along the first direction. The wall of the limiting hole 150a can limit the displacement of the lever assembly 110 relative to the housing 130, the bracket 140, and the top cover 150 along the second direction, thereby reducing the likelihood of the lever assembly 110 disengaging from the switch device when the user drives the lever assembly 110 to move along the second direction. In the initial state of the switch device, the lever assembly 110 is located in the middle of the limiting hole 150a along the second direction.

[0034] In one embodiment, please refer to Figures 3 to 5 The lever assembly 110 includes a lever 111, a top bead 112, and an elastic element 113. The lever 111 abuts against the bracket 140, the top bead 112 abuts against the housing 130, and the two ends of the elastic element 113 abut against the bracket 140 and the top bead 112, respectively. The housing 130 has a driving surface 130a that abuts against the top bead 112. Along the direction of the housing 130 toward the button 200, the distance between the driving surface 130a and the central axis of the housing 130 gradually decreases. When the top bead 112 moves along the second direction, the driving surface 130a can apply a restoring force to the top bead 112 toward the central axis of the housing 130. During the process of the user driving the lever assembly 110 to move along the second direction, the driving surface 130a can move away from the button 200 in the first direction relative to the top bead 112, thereby compressing the elastic element 113. When the user releases the lever assembly 110, the elastic element 113 applies pressure to the drive surface 130a to restore its initial length. This allows the drive surface 130a to apply a reverse restoring force to the top bead 112, enabling the lever assembly 110 to move towards the central axis of the housing 130. Exemplarily, the drive surface 130a is arranged intersecting both the first and second directions, and is parallel to the direction of the pivot of the bracket 140. The elastic element 113 is a linear spring. The lever assembly 110 can be easily reset by contacting the drive surface 130a, resulting in a relatively simple switch device structure. Exemplarily, the top bead 112 is made of a material capable of elastic deformation, such as silicone or rubber, minimizing interference between the lever assembly 110 and the housing 130.

[0035] In one embodiment, please refer to Figure 3The lever 111 includes a lever body 1111 and a pin 1112. The lever body 1111 has a limiting groove 1111a extending along the first direction. The elastic element 113 is located within the limiting groove 1111a. A portion of the structure of the pin 1112 is located within the limiting groove 1111a and is movable relative to the lever body 1111 along the first direction. The pin 1112 has an abutting portion 1112a protruding from the limiting groove 1111a, which is used to abut against a drive button. The pin 1112 is made of silicone or rubber. For example, the drive button is used to contact the user's palm. The user can push the drive button to move along a second direction, thereby causing the pin 1112, which abuts against the drive button, to move along the second direction. The pin 1112 increases the friction between the lever 111 and the drive button, allowing the user to push the lever 111 to move along the second direction more stably. Furthermore, the contact between the ejector pin 1112 and the drive button can reduce the wobbling of the lever 111.

[0036] In one embodiment, please refer to Figure 3 The bracket 140 has a first pushing part 140a and a second pushing part 140b arranged along the second direction. There are two push rods 120, one of which is a first push rod 121 and the other is a second push rod 122. The first pushing part 140a and the second pushing part 140b are used to push the first push rod 121 and the second push rod 122 to move along the first direction, respectively. The number of buttons 210 corresponds to the number of push rods 120. One of the buttons 210 is a first button 211 and the other is a second button 212. The second push rod 122 can push the second button 212 along the first direction. When the first push rod 121 pushes the first button 211, the seat assembly moves along a first preset direction. When the second push rod 122 pushes the second button 212, the seat assembly moves along a second preset direction. The first preset direction and the second preset direction are opposite or intersecting. For example, both the first preset direction and the second preset direction are unidirectional, and the first preset direction and the second preset direction are arranged opposite to each other. The first pushing part 140a and the second pushing part 140b can respectively control the pushing of the first button 211 and the second button 212, thereby enabling the seat assembly to move along the first preset direction and the second preset direction through a single switching device, making it convenient to adjust the position of the seat assembly. For example, when the user drives the lever assembly 110 to move along the first preset direction, the first pushing part 140a abuts against the first push rod 121; when the user drives the lever assembly 110 to move along the second direction, the second pushing part 140b abuts against the second push rod 122.

[0037] It is understood that other embodiments of this application are not limited to the bracket 140 having a first pushing part 140a and a second pushing part 140b, the first pushing part 140a and the second pushing part 140b being used to push the first button 211 and the second button 212 to move, respectively. Exemplarily, the first button 211 and the second button 212 can be driven to move by lever assemblies 110 corresponding to multiple different switching devices.

[0038] In one embodiment, please refer to Figure 3 The push rod 120 includes a guide portion 120a and a pressing portion 120b arranged along the first direction. The guide portion 120a penetrates the housing 130 along the first direction. For example, projected along the first direction, the projection area of ​​the guide portion 120a is within the projection area of ​​the pressing portion 120b. The pressing portion 120b abuts against the end of the housing 130 opposite to the bracket 140. When the push rod 120 moves along the first direction, the pressing portion 120b can abut against the button 210 and push the button 210 to move along the first direction. Through the cooperation of the guide portion 120a and the housing 130, the displacement of the push rod 120 can be guided, so that the push rod 120 can move relatively stably towards the button 210 along the first direction under the action of the bracket 140. Furthermore, when the bracket 140 and the push rod 120 are separated, the push rod 120 can move relatively stably in the first direction away from the button 210 under the push of the restoring force of the button 210, and the push rod 120 and the housing 130 are difficult to separate due to the restriction of the pressing part 120b.

[0039] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it.
