[0036] See also Figure 1 An embodiment of the present application provides a vehicle, which includes a vehicle body and a button device 100. The button device 100 can be installed behind the steering wheel of the vehicle body, which helps the driver to operate the button device 100 more conveniently.

[0037] The button device 100 may be installed behind the steering wheel, which may mean that the button device 100 is installed on the steering wheel and is located behind the steering wheel, or that the button device 100 is installed on other structures of the vehicle body and is located behind the steering wheel.

[0038] In some embodiments, the button device 100 is detachably mounted on the vehicle body, so that the button device 100 can be easily disassembled and repaired without disassembling the vehicle body or the steering wheel, thereby reducing the maintenance cost.

[0039] See also Figures 1 to 3 In some embodiments, the button device 100 includes a bracket 110 , a conductive member 120 , a button, and an adjustment wheel 180 .

[0040] The bracket 110 is installed behind the steering wheel of the vehicle. For example, the bracket 110 and the vehicle body can be fixed by a fixing member. Specifically, the bracket 110 can be provided with a first fixing hole, and the vehicle body can be provided with a second fixing hole. The fixing member can be inserted into the first fixing hole and the second fixing hole to detachably install the bracket 110 on the vehicle body. The fixing member can be a screw, a bolt, a rivet or other fixing structure.

[0041] The conductive member 120 and the bracket 110 are integrally formed, and the conductive member 120 is suitable for electrically connecting to the power supply of the vehicle. In this way, the key device 100 does not need to be provided with a PCB board, which helps to reduce the overall size of the key device 100, and the bracket 110 does not need to reserve an installation position for the PCB board, which reduces the installation process of the bracket 110 and the PCB board and improves the assembly efficiency.

[0042] The conductive member 120 may be a conductive metal strip, and the bracket 110 may be a plastic bracket 110. The conductive member 120 may be integrally formed with the bracket 110 by injection molding. The conductive member 120 may include a plurality of conductive metal strips to form a plurality of circuits to adapt to different buttons.

[0043] For example, the key device 100 may further include a plurality of pins, which may be electrically connected to different conductive members 120, and the pins may be integrally formed with the bracket 110. The pins may be used as plugs to be plugged into the sockets on the vehicle body for power supply and signal transmission.

[0044] The button is connected to the bracket 110 , and the button is suitable for being electrically connected to the conductive member 120 . For example, when the driver operates the button, the button and the conductive member 120 are electrically connected, so that the circuit corresponding to the button is turned on to achieve signal transmission.

[0045] There are multiple buttons, including a volume up button 130, a volume down button 140, a mute button 150, a mode button 160, and an audio signal source switching button 170. In this way, the button device 100 integrates multiple buttons, and the driver can operate the buttons at a close distance when operating the steering wheel to make various adjustments to the volume, mode, and audio signal source, which helps the driver to operate the buttons more conveniently and reduces the safety hazards when the driver operates the buttons during driving. Among them, the mute button 150 can be used to achieve functions such as muting, answering the call, and hanging up the call. The audio signal source switching button 170 can be a Source button.

[0046] The adjustment wheel 180 is rotatably connected to the bracket 110 and electrically connected to the conductive member 120. The adjustment wheel 180 is rotated to adjust the volume, mode or audio signal source. In this way, the driver can adjust the volume, mode or audio signal source more conveniently by rotating the adjustment wheel 180 without repeatedly operating the buttons, further reducing the safety hazard when the driver operates the button device 100 during driving.

[0047] In some embodiments, the bracket 110 may include a bracket body 111 and a connecting bracket 113110. The bracket body 111 and the connecting bracket 113110 may be connected by a fixing member, and the connecting bracket 113110 and the vehicle body may also be connected by a fixing member. The fixing member may be a screw, a bolt, a rivet or other fixing structure.

[0048] The bracket body 111 and the conductive member 120 may be integrally formed.

[0049] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the adjustment roller 180 may include an integrally formed roller body 181 and a conductive spring sheet 182. The roller body 181 is rotatably connected to the bracket 110, and one end of the conductive spring sheet 182 facing away from the roller body 181 is movably abutted against the conductive member 120. When the roller body 181 rotates, the conductive spring sheet 182 is driven to rotate synchronously, and the conductive spring sheet 182 contacts the conductive member 120 to realize signal transmission to adjust the volume, mode or audio signal source.

[0050] For example, the bracket 110 may include a mounting post 1111, which may be protruded from the bracket body 111, and the roller body 181 may be rotatably sleeved on the mounting post 1111. The conductive spring 182 is located at one end of the roller body 181 facing the bracket body 111 to abut against the conductive member 120.

[0051] The roller body 181 may be a plastic roller body 181, and the conductive spring 182 may be a metal conductive spring 182. The conductive spring 182 and the roller body 181 may be injection molded into an integral structure, so that there is no need to set a connection structure between the conductive spring 182 and the roller body 181, which helps to make the conductive spring 182 and the roller body 181 more firmly connected, and reduces the installation process between the conductive spring 182 and the roller body 181, thereby improving assembly efficiency.

[0052] In some embodiments, the button device 100 may further include an abutment 190, one end of which may be connected to the bracket 110, and the abutment 190 may be located on one side of the roller body 181 along the radial direction. The outer peripheral surface of the roller body 181 may be provided with a plurality of protrusions 1811, and the protrusions 1811 may abut against the abutment 190. In this way, when the adjusting roller 180 rotates, the protrusions 1811 on the outer peripheral surface of the roller body 181 abut against the abutment 190, and friction is generated between the protrusions 1811 and the abutment 190 to provide a damping effect for the rotation of the adjusting roller 180, and provide the driver with a feel of rotating the adjusting roller 180, and when the adjusting roller 180 does not rotate, the abutment 190 may limit the adjusting roller 180, which helps to prevent the adjusting roller 180 from rotating.

[0053] See also Figures 2 to 3 In some embodiments, the volume up button 130, the volume down button 140, and the mute button 150 all include a first button body 131 and a first trigger component, that is, the structures of the volume up button 130, the volume down button 140, and the mute button 150 can be roughly the same, the volume up button 130 can include the first button body 131 and the first trigger component, the volume down button 140 can also include the first button body 131 and the first trigger component, and the mute button 150 can also include the first button body 131 and the first trigger component.

[0054] For ease of description, the following explanation will be given using one of the volume up button 130 , the volume down button 140 , and the mute button 150 .

[0055] The first button body 131 may include a pressing portion 1311, a rotating portion 1312 and a driving portion 1313 connected in sequence, the rotating portion 1312 is rotatably connected to the bracket 110, the first trigger is connected to the pressing portion 1311 and is located between the pressing portion 1311 and the conductive member 120, the driving portion 1313 rotates after receiving the driving force, driving the pressing portion 1311 to rotate in the same direction, and the pressing portion 1311 drives the first trigger to be electrically connected to the conductive member 120, so that the driver can turn the driving portion 1313 to rotate, thereby driving the pressing portion 1311 to rotate, so that the first trigger can be electrically connected to the conductive member 120, and the second trigger conducts the corresponding circuit to achieve signal transmission. For example, the first trigger can be a metal conductive member.

[0056] For example, the driver can turn the driving part 1313. After the driving part 1313 is subjected to force, the rotating part 1312 starts to rotate, driving the pressing part 1311 to rotate toward the conductive member 120, driving the first trigger member to contact the conductive member 120, so that the circuit is turned on and the signal is transmitted. In this way, when the driver operates the volume increase button 130, the volume decrease button 140 and the mute button 150, the driver can easily turn the volume increase button 130, the volume decrease button 140 and the mute button 150 without taking both hands off the steering wheel, which helps the driver to operate the button device 100 more conveniently and further reduces the safety hazards when the driver operates the buttons.

[0057] The volume up button 130, the volume down button 140 and the mute button 150 can be arranged side by side and adjacent to each other for easy operation by the driver. It can be understood that the arrangement order of the volume up button 130, the volume down button 140 and the mute button 150 can be designed according to the needs, and this application does not limit it.

[0058] In some embodiments, the bracket 110 is provided with a rotation groove 1115 and three limit grooves, the three limit grooves are all connected to the rotation groove 1115, and the three limit grooves are distributed along the length direction of the rotation groove 1115; each rotating part 1312 is rotatably located in a limit groove, and the rotating part 1312 is protrudingly provided with a rotating shaft 1314, and the rotating shaft 1314 is rotatably located in the rotation groove 1115, which helps the volume up button 130, the volume down button 140 and the mute button 150 to rotate stably.

[0059] Specifically, for ease of description, the three limiting grooves can be respectively named as the first limiting groove 1112, the second limiting groove 1113, and the third limiting groove 1114. The rotating shafts 1314 protruding from the rotating parts 1312 of the volume increase button 130, the mute button 150, and the volume decrease button 140 are respectively named as the first rotating shaft, the second rotating shaft, and the third rotating shaft.

[0060] The first limiting groove 1112 , the second limiting groove 1113 , and the third limiting groove 1114 are all connected to the rotation groove 1115 , and the first limiting groove 1112 , the second limiting groove 1113 , and the third limiting groove 1114 are distributed along the length direction of the rotation groove 1115 .

[0061] It should be noted that the first limiting groove 1112, the second limiting groove 1113, and the third limiting groove 1114 are distributed along the length direction of the rotating groove 1115, which may refer to the first limiting groove 1112, the second limiting groove 1113, and the third limiting groove 1114 being arranged along the length direction of the rotating groove 1115 according to needs, for example, the first limiting groove 1112, the second limiting groove 1113, and the third limiting groove 1114 are distributed in sequence, or the second limiting groove 1113, the first limiting groove 1112, and the third limiting groove 1114 are distributed in sequence, or the third limiting groove 1114, the second limiting groove 1113, and the first limiting groove 1112 are distributed in sequence, and so on.

[0062] Among them, the rotating part 1312 of the volume up button 130 can be rotatably located in the first limiting groove 1112, and the first limiting groove 1112 can limit the movement of the rotating part 1312 of the volume up button 130 along the length direction of the rotating groove 1115, thereby limiting the movement of the volume up button 130 along the length direction of the rotating groove 1115.

[0063] The rotating portion 1312 of the volume increase button 130 is provided with a first rotating shaft, which is rotatably located in the rotating groove 1115, which helps the volume increase button 130 to rotate stably. In particular, along the length direction of the rotating groove 1115, the first rotating shafts are convexly provided on opposite sides of the rotating portion 1312 of the volume increase button 130, and the two first rotating shafts are coaxially arranged and are both rotatably located in the rotating groove 1115, which helps the volume increase button 130 to rotate more stably.

[0064] It can be understood that the rotating portion 1312 of the mute button 150 is rotatably located in the second limiting groove 1113, and the rotating portion 1312 of the volume reduction button 140 is convexly provided with a second rotating shaft, and the second rotating shaft is rotatably located in the rotating groove 1115. The rotating portion 1312 of the volume reduction button 140 is rotatably located in the third limiting groove 1114, and the rotating portion 1312 of the mute button 150 is convexly provided with a third rotating shaft, and the third rotating shaft is rotatably located in the rotating groove 1115. The rotating portion 1312 of the volume reduction button 140, the second rotating shaft, and the installation method and structure of the rotating portion 1312 and the second rotating shaft of the mute button 150 can all refer to the volume increase button 130, and will not be repeated.

[0065] In some embodiments, the bracket 110 may be provided with a first stopper 1116 , a second stopper 1117 , a third stopper 1118 and a fourth stopper 1119 which are arranged at intervals.

[0066] The pressing portion 1311 of the volume increase button 130 is rotatably located between the first stopper 1116 and the second stopper 1117. In this way, the first stopper 1116 and the second stopper 1117 can further limit the movement of the volume increase button 130 along the length direction of the rotation slot 1115, which helps the volume increase button 130 to rotate more stably. For example, the first stopper 1116 and the second stopper 1117 can be distributed along the length direction of the rotation slot 1115. There can be a gap between the pressing portion 1311 of the volume increase button 130 and the bracket body 111 so that the pressing portion 1311 can rotate.

[0067] The pressing portion 1311 of the mute button 150 is rotatably located between the second stopper 1117 and the third stopper 1118, so that the second stopper 1117 and the third stopper 1118 can further limit the movement of the mute button 150 along the length direction of the rotation slot 1115, which helps the mute button 150 to rotate more stably. For example, the third stopper 1118 and the second stopper 1117 can be distributed along the length direction of the rotation slot 1115. There can be a gap between the pressing portion 1311 of the mute button 150 and the bracket body 111 so that the pressing portion 1311 can rotate.

[0068] The pressing portion 1311 of the volume reduction button 140 is rotatably located between the third limiting member 1118 and the fourth limiting member 1119, so that the third limiting member 1118 and the fourth limiting member 1119 can further limit the movement of the volume reduction button 140 along the length direction of the rotation slot 1115, which helps the volume reduction button 140 to rotate more stably. For example, the third limiting member 1118 and the fourth limiting member 1119 can be distributed along the length direction of the rotation slot 1115. There can be a gap between the pressing portion 1311 of the volume reduction button 140 and the bracket body 111 so that the pressing portion 1311 can rotate.

[0069] For example, in this embodiment, the first limiting member 1116 , the second limiting member 1117 , the third limiting member 1118 and the fourth limiting member 1119 may be distributed in sequence along the length direction of the rotating groove 1115 .

[0070] In some embodiments, the button device 100 may further include a first elastic member 210, which may be connected between the pressing portion 1311 and the conductive member 120, and the first triggering member is connected to the first elastic member 210. The first elastic member 210 is suitable for driving the first triggering member and the pressing portion 1311 away from the conductive member 120. In this way, when the driver releases the button, the first elastic member 210 can drive the first triggering member and the pressing portion 1311 away from the conductive member 120, and the pressing portion 1311 drives the driving portion 1313 to rotate in the same direction when rotating, so that the driving portion 1313 can return to its original position to facilitate the driver's next operation. In addition, when the driver dials the volume increase button 130, the volume decrease button 140 or the mute button 150, the first elastic member 210 can provide a small resistance to provide the user with a feel of dialing the button.

[0071] As an example, the first elastic member 210 may be a silicone member, and the first elastic member 210 may include a first body 211 and a first pressing protrusion 212, and the first pressing protrusion 212 is convexly arranged on the first body 211. A groove is arranged in the first pressing protrusion 212, and the notch of the groove faces the conductive member 120. The first trigger member may be located in the groove, for example, the first trigger member may be bonded to the first elastic member 210. A snap-fit ​​groove may be arranged on the side of the pressing portion 1311 facing the conductive member 120, and the first pressing protrusion 212 may be snap-fitted into the snap-fit ​​groove. In this way, when the driving part 1313 is rotated by force, the pressing part 1311 is driven to rotate toward the side of the conductive part 120, and the pressing part 1311 squeezes the first pressing protrusion 212, and the first pressing protrusion 212 is deformed so that the first trigger part can contact the conductive part 120; when the force acting on the driving part 1313 disappears, the elastic restoring force generated by the deformation of the first pressing protrusion 212 can drive the pressing part 1311 and the first trigger part away from the conductive part 120, thereby driving the driving part 1313 back to its original position.

[0072] In some embodiments, the mode button 160 and the audio signal source switching button 170 both include a second button body 161 and a second trigger component, that is, the structures of the mode button 160 and the audio signal source switching button 170 can be roughly the same, the mode button 160 can include a second button body 161 and a second trigger component, and the audio signal source switching button 170 can also include a second button body 161 and a second trigger component.

[0073] For ease of understanding, the following explanation will be given using one of the mode button 160 and the audio signal source switching button 170 .

[0074] The second button body 161 is movably mounted on the bracket 110, the second trigger is connected to the second button body 161 and is located between the second button body 161 and the conductive member 120, and the second button body 161 is suitable for driving the second trigger to be electrically connected to the conductive member 120, so that the driver can press the second button body 161 to connect the second trigger to the conductive member 120, and the second trigger conducts the corresponding circuit to achieve signal transmission. For example, the second trigger can be a metal conductive member.

[0075] In some embodiments, the second button body 161 of the mode button 160 and the second button body 161 of the audio signal source switching button 170 can be respectively located on opposite sides of the bracket body 111. For example, along the length direction of the rotating groove 1115, the second button body 161 of the mode button 160 and the second button body 161 of the audio signal source switching button 170 can be respectively located on opposite sides of the bracket body 111, so that the user can better distinguish the mode button 160 and the audio signal source switching button 170.

[0076] In some embodiments, the button device 100 may also include a second elastic member 220, which is connected between the second button body 161 and the conductive member 120, and the second trigger member is connected to the elastic member. The second elastic member 220 is suitable for driving the second trigger member and the second button body 161 away from the conductive member 120. In this way, the second elastic member 220 can provide a pressing feel for the user to press the mode button 160 and the audio signal source switching button 170, and the second elastic member 220 can drive the second trigger member and the second button body 161 back to their original position to facilitate the driver to press the button next time.

[0077] As an example, the second elastic member 220 may be a silicone member, and the second elastic member 220 may include a second body 221 and a second pressing protrusion 222, and the second pressing protrusion 222 is convexly arranged on the second body 221. A groove is arranged in the second pressing protrusion 222, and the notch of the groove faces the conductive member 120. The second trigger member may be located in the groove, for example, the second trigger member may be bonded to the second elastic member 220. A guide column and a fixing column may be convexly arranged on the side of the second key body 161 facing the conductive member 120, and the bracket 110 may be provided with a guide hole and a fixing hole, and the guide column may be inserted into the guide hole, and the fixing column may be inserted into the fixing hole. A fixing portion may be arranged around the outer peripheral surface of the end of the fixing column, and the fixing portion may abut against the bracket 110, which helps to prevent the fixing column from being separated from the fixing hole, thereby helping to prevent the second key body 161 from being separated from the bracket 110. An open groove may also be arranged on the end surface of the fixing column, so that the end of the fixing column can squeeze the open groove to reduce the size of the end of the fixing column, which helps to conveniently insert the fixing column into the fixing hole. Thus, when the second button body 161 is forced to move toward the conductive member 120, the second button body 161 squeezes the second pressing protrusion 222, and the second pressing protrusion 222 is deformed, so that the second triggering member can contact the conductive member 120. When the force acting on the second button body 161 disappears, the elastic restoring force generated by the deformation of the second pressing protrusion 222 can drive the second button body 161 and the second triggering member away from the conductive member 120, thereby driving the second button body 161 and the second triggering member back to their original positions.

[0078] In some embodiments, the first elastic member 210 and the second elastic member 220 may be an integral structure, which helps to reduce assembly steps and improve assembly efficiency.

[0079] In the button device 100 and the vehicle provided in the embodiment of the present application, the bracket 110 is installed behind the steering wheel of the vehicle, the conductive member 120 and the bracket 110 are integrally formed, the conductive member 120 is suitable for electrically connecting to the power supply of the vehicle, the button is connected to the bracket 110, the button is suitable for electrically connecting to the conductive member 120, the number of buttons is multiple, and the multiple buttons include a volume increase button 130, a volume decrease button 140, a mute button 150, a mode button 160 and an audio signal source switching button 170. In this way, multiple buttons are integrated on the button device 100, and the driver can operate the buttons at a close distance when operating the steering wheel to make various adjustments to the volume, mode and audio signal source, which helps the driver to operate the buttons more conveniently and reduces the safety hazards when the driver operates the buttons during driving. The adjustment wheel 180 is rotatably connected to the bracket 110 and electrically connected to the conductive member 120. The adjustment wheel 180 is rotated to adjust the volume, mode or audio signal source. In this way, the driver can adjust the volume, mode or audio signal source more conveniently by rotating the adjustment wheel 180 without repeatedly operating the buttons, further reducing the safety hazard when the driver operates the button device 100 during driving.

Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
