[0018] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0019] The existing magnetic suction control device is difficult to simultaneously meet the technical problems of stable adsorption and convenient picking up.

[0020] To this end, the present application provides a self-detachable magnetic attraction component on one hand, wherein the self-detachable magnetic attraction component is arranged in a connecting body, and the connecting body can be magnetically connected to a to-be-connected portion through the self-detachable magnetic attraction component, characterized in that the self-detachable magnetic attraction component includes: A magnetic attraction member, the magnetic attraction member is located in the connecting body and can be magnetically connected to the part to be connected; A first sensor component and a circuit board, wherein the first sensor component is electrically connected to the magnetic attraction component through the circuit board; A first moving part, the first moving part is connected to the connecting body, the first moving part forms a relative motion with respect to the first sensing part, and the self-separating magnetic attraction component forms a first motion state and a second motion state of the self-separating magnetic attraction component according to the relative motion relationship between the first moving part and the first sensing part; wherein, In the first movement state, the magnetic attraction member forms a magnetic attraction force, and the magnetic attraction member is magnetically connected to the portion to be connected; In the second movement state, the magnetic attraction force in the magnetic attraction member disappears, and the magnetic attraction member is separated from the portion to be connected.

[0021] On the other hand, the present application provides a control device, characterized in that it includes the self-detachable magnetic suction component described in Example 1, Example 2, or Example 3, and the control device also includes: A connecting body, wherein the self-detachable magnetic attraction component is located inside the connecting body.

[0022] Embodiment 1: Please refer to the attached Figure 1 To Attachment Figure 2 As shown, a specific implementation of the self-detachable magnetic suction component 10 of the present application is shown. In the prior art, the control device is magnetically connected to the connection point through the magnetic suction component, and the strength of the magnetic suction force in the magnetic suction component is directly related to the fixing effect of the control device. How to properly select the strength of the magnetic suction force in the magnetic suction component so that the control device can be stably adsorbed and conveniently taken when it needs to be moved has always been a difficulty and pain point in the industry. That is, when the magnetic suction force of the magnetic suction component is too strong, although the control device can be stably adsorbed, when the control device needs to be moved, it is difficult for the control device to move due to the excessively strong magnetic suction force in the magnetic suction component. When the magnetic suction force of the magnetic suction component is too weak, although the control device can be relatively easily moved, there is a risk that the control device will fall from the connection point due to the weak magnetic suction force of the magnetic suction component. Furthermore, in the present application, the self-detachable magnetic component 10 is installed in a movable knob, and the movable knob needs to switch between different functions by changing the adsorption position, that is, when the knob with the self-detachable magnetic component 10 is placed on the door, the window can be raised and lowered, and when the knob with the self-detachable magnetic component 10 is placed on the side of the seat, the seat can be adjusted. The self-detachable magnetic component 10 is set in the knob only as a specific embodiment of the present application, and the self-detachable magnetic component 10 can also be set in other devices that need to be magnetically attracted and need to be moved.

[0023] Please refer to the attached Figure 1 And attached Figure 2 As shown, the first direction X of the present application refers to the height direction of the self-detachable magnetic assembly 10, that is, the direction from top to bottom of the self-detachable magnetic assembly 10 or the direction from bottom to top of the self-detachable magnetic assembly 10. In the present application, the connection panel 700 is arranged above the first connection part 800, and the first connection part 800 is arranged below the connection panel 700.

[0024] Attached Figure 1 1 is a structural schematic diagram of the self-detachable magnetic attraction component 10 in the first motion state in the embodiment 1 of the present application. Figure 2 This is a structural diagram of the self-detachable magnetic attraction component 10 in the second motion state in the embodiment 1 of the present application. Figure 1 And attached Figure 2 As shown, the self-detachable magnetic component 10 of the present application is used in combination with the connecting body 20, that is, the self-detachable magnetic component 10 is arranged in the connecting body 20, and as a part of the connecting body 20, it can be magnetically connected to the connection point 30. The magnetic connection means that the self-detachable magnetic component 10 has two states, one is that the self-detachable magnetic component 10 is magnetically connected to the connection point 30 when it has magnetic attraction, and the other is that the self-detachable magnetic component 10 can be separated from the connection point 30 when it does not have magnetic attraction.

[0025] Among them, the connection body 20 is a component for carrying the self-separating magnetic suction component 10. In the present application, the connection body 20 can be a control component for realizing the button function, and the control component can realize different functions by moving the adsorption position. Further, the connection body 20 includes a first connection part 800, which is hollow. The first connection part 800 is the main component of the connection body 20, and most of the structures in the self-separating magnetic suction component 10 are arranged around the first connection part 800. The connection body 20 also includes a connection panel 700, which is located at the top of the first connection part 800 along the first direction X. The connection panel 700 is fixedly connected to the first connection part 800 and forms a cover for the hollow cavity in the first connection part 800. The first connection part 800 is a horizontal connection structure 810 arranged horizontally in the hollow cavity to fix other components, and the horizontal connection structure 810 is fixedly connected to the first connection part 800.

[0026] Among them, the place to be connected 30 refers to the place connected to the self-separating magnetic suction component 10. There can be more than two places to be connected 30, so the self-separating magnetic suction component can be adsorbed on different places to be connected 30 according to different implementation modes as needed. Furthermore, the place to be connected 30 can be different adsorption points in the car. In one embodiment, the place to be connected 30 includes a metal layer 32, and the metal layer 32 is the main structure for realizing magnetic attraction with the self-separating magnetic suction component 10. The place to be connected 30 may also include a base 31 and a surface coating layer 33, the base 31 is located at the bottom of the metal layer 32, and the surface coating layer 33 is located at the top of the metal layer 32.

[0027] In one embodiment, the connection panel 700 and the first connection portion 800 are fixedly connected by means of snaps, glue, etc.

[0028] Please refer to the attached Figure 1 And attached Figure 2 As shown, the self-detachable magnetic suction assembly 10 of the present application includes a circuit board 300, and a control element is integrated in the circuit board 300 of the present application to switch back and forth between the first motion state and the second motion state according to the different relative positions between the first moving part 400 and the first sensor part 200. The circuit board 300 of the present application can also be used as an intermediate part to fix other components. Furthermore, the circuit board 300 is horizontally arranged in the first connecting part 800, and the circuit board 300 is located on one side of the transverse connecting structure 810, and the circuit board 300 is fixedly connected to the transverse connecting structure 810 through the first connecting part 310.

[0029] In one embodiment, the first connecting member 310 is a connecting bolt or a connecting buckle.

[0030] Please refer to the attached Figure 1 And attached Figure 2 As shown, the self-detachable magnetic component 10 of the present application includes a magnetic component 100, which is the main component of the self-detachable magnetic component 10. The connecting body 20 is connected to the part 30 to be connected by the magnetic component 100 to achieve a magnetic connection. The magnetic component 100 is located in the connecting body 20, and the magnetic component 100 is electrically connected to the circuit board 300, that is, the control element in the circuit board 300 can control the presence or absence of magnetic attraction in the magnetic component 100. The magnetic component 100 has a magnetic surface at the bottom along the first direction X, and the magnetic surface in the magnetic component 100 contacts the part to be connected to achieve a magnetic connection.

[0031] In one embodiment, the magnetic member 100 is fixedly connected to the circuit board 300 , and the magnetic member 100 is located at the bottom of the circuit board 300 along the first direction X.

[0032] In one embodiment, the magnetic component 100 is a power-on demagnetization structure or a power-on magnetization structure. The magnetic component 100 with a power-on demagnetization structure means that the magnetic component 100 has a magnetic attraction when it is not powered, and the magnetic attraction of the magnetic component 100 disappears after power is applied. The power-on magnetization structure means that the magnetic component 100 does not have a magnetic attraction when it is not powered, and the magnetic component 100 has a magnetic attraction after power is applied. Further, the magnetic component 100 of the present application is a power-on demagnetization structure.

[0033] Please refer to the attached Figure 1 And attached Figure 2 As shown, the self-detachable magnetic suction component 10 of the present application also includes a first sensor component 200, and the first sensor component 200 is electrically connected to the circuit board 300, that is, the first sensor component 200 is electrically connected to the magnetic suction component 100 through the circuit board 300, and the control element in the circuit board 300 is used to receive the detection signal of the first sensor component 200, and further control the magnetic suction component 100 to have a magnetic suction force or the magnetic suction force disappears according to the detection signal of the first sensor component 200.

[0034] In one embodiment, the first sensor 200 is a distance detection unit, and the first sensor 200 is disposed at the bottom of the circuit board 300 along the first direction X.

[0035] Please refer to the attached Figure 1 And attached Figure 2 As shown. The self-separating magnetic suction component 10 of the present application also includes a first moving part 400, which is connected to the connecting body 20, and the first moving part 400 is arranged at the bottom of the connecting body 20 along the first direction X. Further, the first moving part 400 is arranged at the bottom of the first connecting part 800 along the first direction X. The first moving part 400 is penetrated by a first through hole 430 along the first direction X, and the first through hole 430 is located in the central area of ​​the first moving part 400. The magnetic suction surface of the magnetic suction part 100 passes through the first through hole 430, and the magnetic suction surface of the magnetic suction part 100 is located outside the first through hole 430. The first moving part 400 also includes a first area 410 and a second area 420. The second area 420 is arranged near the first through hole 430. Further, the second area 420 is an area of ​​the first moving part 400 near the first through hole 430, and the second area 420 is fixedly connected to the magnetic suction part 100. The first region 410 is disposed at an edge of the first moving member 400 , and the first region 410 is fixedly connected to the first connecting portion 800 .

[0036] Furthermore, the first moving part 400 can form a relative movement with respect to the first sensing part 200, and the self-detachable magnetic suction component 10 forms a first movement state and a second movement state of the self-detachable magnetic suction component 10 according to the relative movement relationship between the first moving part 400 and the first sensing part 200. Among them, in the first movement state, the magnetic suction component 100 forms a magnetic suction force, and the magnetic suction component 100 is magnetically connected to the part to be connected 30. In the second movement state, the magnetic suction force in the magnetic suction component 100 disappears, and the magnetic suction component 100 is separated from the part to be connected 30. Therefore, a magnetic suction connection can be achieved by switching between the first movement state and the second movement state, so as to facilitate stable adsorption and easy picking between the self-detachable magnetic suction component 10 and the part to be connected 30.

[0037] In one embodiment, the relative movement between the first moving part 400 and the first sensor part 200 is the up and down movement of the first moving part 400 relative to the first sensor part 200 along the first direction X. When the first moving part 400 moves up and down relative to the first sensor part 200 along the first direction X, the spacing formed between the first moving part 400 and the first sensor part 200 in the first direction X changes, and the first sensor part 200 is used to detect the spacing between the first sensor part 200 and the first moving part 400 in the first direction X. The first moving part 400 is made of a flexible material, and the flexible material in this application refers to a flexible plastic or rubber. Further, there is a movement gap between the first connecting part 800 and the first moving part 400, and there is also a movement gap between the circuit board 300 and the first connecting part 310. Therefore, the first moving part 400 can be deformed under the premise that the first sensor part 200 and the magnetic suction part 100 do not move in the first direction X.

[0038] In the process of lifting the connection body 20, since the second area 420 in the first moving member 400 is connected to the connection body 20, and the first area 410 in the first moving member 400 is connected to the magnetic member 100, the height difference of the first moving member 400 in the first direction X shows a trend of gradually increasing from the second area 420 to the first area 410, that is, the first area 410 in the first moving member 400 is closer to the first sensor 200 than the second area 420. At this time, the area corresponding to the first sensor 200 and the first moving member 400 is a partial area between the first area 410 and the second area 420. After the connection body 20 is lifted, the distance between the area and the first sensor 200 is shortened at the same time, and the first sensor 200 can detect the distance between the first sensor 200 and the area.

[0039] Among them, if the first sensor 200 detects that the distance between the first sensor 200 and the first moving part 400 is continuously shortened, the first movement state of the self-detachable magnetic suction component 10 is switched to the second movement state, and the continuous shortening of the distance between the first sensor 200 and the first moving part 400 refers to a process in which the distance between the first sensor 200 and the first moving part 400 is continuously shortened after the connection body 20 is continuously lifted, thereby avoiding the false touch action of the magnetic suction component 100 being demagnetized after the distance between the first sensor 200 and the first moving part 400 fluctuates in the case of bumps. If the first sensor 200 detects that the distance between the first sensor 200 and the first moving part 400 is the first distance, the second movement state of the self-detachable magnetic suction component 10 is switched to the first movement state. The first distance refers to the normal distance between the first sensor 200 and the first moving part 400 when the connection body 20 is not lifted.

[0040] Please refer to the attached Figure 1 And attached Figure 2 As shown, the self-detachable magnetic suction assembly 10 of the present application also includes a second sensor 500, which is arranged on the first moving member 400. The second sensor 500 and the first sensor 200 are arranged correspondingly along the first direction X. When the first moving member 400 forms a relative motion relative to the first sensor 200, the second sensor 500 simultaneously forms a relative motion relative to the first sensor 200. The second sensor 500 is arranged to further realize the detection of the relative distance between the first sensor 200 and the first moving member 400. In one embodiment, the first sensor 200 is an infrared distance detection device, and the second sensor 500 is used to reflect the infrared rays emitted by the first sensor 200.

[0041] Please refer to the attached Figure 1 And attached Figure 2 As shown, the self-detachable magnetic suction component 10 of the present application also includes a first sensing member 600, and the first sensing member 600 is provided to further prevent the occurrence of accidental touches. The first sensing member 600 is provided at the top of the connecting body 20 along the first direction X. Under the triggering of the first sensing member 600, the self-detachable magnetic suction component 10 switches between the first motion state and the second motion state. Further, under the triggering of the first sensing member 600, and the first sensing member 200 detects that the distance between the first sensing member 200 and the first moving member 400 is continuously shortened, the self-detachable magnetic suction component 10 can switch the first motion state to the second motion state. Under the triggering of the first sensing member 600, the first sensing member 200 detects that the distance between the first sensing member 200 and the first moving member 400 is the first distance, and the self-detachable magnetic suction component 10 can switch the second motion state to the first motion state. Therefore, the provision of the first sensing member 600 can further prevent the occurrence of accidental touches.

[0042] Embodiment 2: Attached Figure 3 1 is a schematic diagram of the structure of the self-detachable magnetic attraction component 10 in the first motion state in the second embodiment of the present application. Figure 4 This is a structural diagram of the self-detachable magnetic attraction component 10 in the second motion state in the embodiment 2 of the present application. Figure 3 And attached Figure 4 As shown, the self-detachable magnetic attraction component 10 in this embodiment is different from the self-detachable magnetic attraction component 10 in Example 1 only in the partial structure of the connecting body 20 and the arrangement positions of the first sensor 200 and the first moving part 400.

The magnetic connection means that the self-detachable magnetic component 10 has two states, one is that the self-detachable magnetic component 10 is magnetically connected to the connection point 30 when it has magnetic attraction, and the other is that the self-detachable magnetic component 10 can be separated from the connection point 30 when it does not have magnetic attraction.

[0044] Among them, the connection body 20 is a component for carrying the self-separating magnetic suction component 10. In the present application, the connection body 20 can be a control component for realizing the button function, and the control component can realize different functions by moving the adsorption position. Further, the connection body 20 includes a first connection part 800, which is hollow. The first connection part 800 is the main component of the connection body 20. Most of the structures in the self-separating magnetic suction component 10 are arranged around the first connection part 800, and the bottom surface of the first connection part 800 is flush with the magnetic suction surface of the magnetic suction part 100. The connection body 20 also includes a connection panel 700, which is located at the top of the first connection part 800 along the first direction X.

Further, the first moving part 400 is arranged in the second through hole of the connecting panel 700, and the first moving part 400 is connected to the inner wall of the second through hole. The first moving part 400 can form a relative movement relative to the first sensor 200, and the self-separating magnetic suction component 10 forms a first movement state and a second movement state of the self-separating magnetic suction component 10 according to the relative movement relationship between the first moving part 400 and the first sensor 200. Among them, in the first movement state, the magnetic suction component 100 forms a magnetic suction force, and the magnetic suction component 100 is magnetically connected to the connection point 30. In the second movement state, the magnetic suction force in the magnetic suction component 100 disappears, and the magnetic suction component 100 is separated from the connection point 30. Therefore, the magnetic connection can be realized by switching between the first motion state and the second motion state, so as to facilitate the stable adsorption and easy removal between the self-detachable magnetic component 10 and the connection point 30.

[0048] In one embodiment, the relative movement between the first moving member 400 and the first sensing member 200 is the up-and-down movement of the first moving member 400 relative to the first sensing member 200 along the first direction X. When the first moving member 400 moves up-and-down relative to the first sensing member 200 along the first direction X, the distance between the first moving member 400 and the first sensing member 200 in the first direction X changes, and the first sensing member 200 is used to detect the distance between the first sensing member 200 and the first moving member 400 in the first direction X. The first moving member 400 is made of an elastic material, which in this application refers to elastic plastic or rubber.

[0049] When the first moving member 400 is pressed down, the first moving member 400 is depressed downward, and the distance between the first moving member 400 and the first sensor 200 is shortened at the same time, and the first sensor 200 can detect the distance between the first sensor 200 and the first moving member 400. When the pressure on the first moving member 400 is canceled, the first moving member 400 rebounds upward and returns to a normal state, and the distance between the first moving member 400 and the first sensor 200 in the normal state is the first distance.

[0050] Among them, if the first sensor 200 detects that the distance between the first sensor 200 and the first moving part 400 is continuously shortened, the first movement state of the self-detachable magnetic suction component 10 is switched to the second movement state, and the continuous shortening of the distance between the first sensor 200 and the first moving part 400 refers to a process in which the distance between the first sensor 200 and the first moving part 400 is continuously shortened during the process of continuously pressing the first moving part 400, thereby avoiding the false touch action of the magnetic suction component 100 being demagnetized after the distance between the first sensor 200 and the first moving part 400 fluctuates in the case of bumps. If the first sensor 200 detects that the distance between the first sensor 200 and the first moving part 400 is the first distance, the second movement state of the self-detachable magnetic suction component 10 is switched to the first movement state. The first distance refers to the normal distance between the first sensor 200 and the first moving part 400 when the first moving part 400 is not pressed down.

Figure 6 Schematic diagram of a structure between the connecting body 20 and the first moving member 400 in Embodiment 3 of the present application. Figure 5 And attached Figure 6 As shown, the self-detachable magnetic attraction assembly 10 in this embodiment is different from the self-detachable magnetic attraction assembly 10 in Example 1 only in the partial structure of the connecting body 20 and the arrangement positions of the first sensor 200 and the first moving member 400. For the same parts as those in Example 1, please refer to the description of Example 1, and Example 3 will not be repeated.

[0052] Please refer to the attached Figure 5 And attached Figure 6As shown, the self-detachable magnetic component 10 of the present application is used in combination with the connecting body 20, that is, the self-detachable magnetic component 10 is arranged in the connecting body 20, and as a part of the connecting body 20, it can be magnetically connected to the connection point 30. The magnetic connection means that the self-detachable magnetic component 10 has two states, one is that the self-detachable magnetic component 10 is magnetically connected to the connection point 30 when it has magnetic attraction, and the other is that the self-detachable magnetic component 10 can be separated from the connection point 30 when it does not have magnetic attraction.

[0053] Among them, the connecting body 20 is a component for carrying the self-detachable magnetic suction component 10. In the present application, the connecting body 20 can be a control component for realizing the key function, and the control component can realize different functions by moving the adsorption position. Further, the connecting body 20 includes a first connecting part 800 and a second connecting part 900 arranged in sequence along the first direction X, the second connecting part 900 is located at the bottom of the first connecting part 800 along the first direction X, and the second connecting part 900 extends along the first direction X toward one side of the first connecting part 800. A connecting rod 930 is extended, and the connecting rod 930 is connected to the first connecting part 800 through a second connecting member 910. And the bottom surface of the second connecting part 900 along the first direction X is arranged flush with the magnetic suction surface of the magnetic suction member 100.

[0054] In one embodiment, the second connecting member 910 is a snap-fit ​​structure, and the second connecting member 910 is snap-fitted to the first connecting portion 800 and the second connecting portion 900 .

[0055] Please refer to the attached Figure 5 And attached Figure 6 As shown, the self-detachable magnetic suction assembly 10 of the present application also includes a first moving member 400, which is connected to the connecting body 20, and the first moving member 400 is arranged at the bottom of the connecting body 20 along the first direction X. Further, the first moving member 400 is half wrapped outside the second connecting part 900, and the first moving member 400 is rotatably connected to the second connecting part 900, and the side of the first moving member 400 is exposed outside the connecting body 20, and the relative rotation between the first moving member 400 and the second connecting part 900 is achieved by driving the side of the first moving member 400. The connecting rod 930 extends upward along the first direction X and passes through the first moving member 400. When the second connecting part 900 rotates relative to the first moving member 400, the connecting rod 930 forms a motion track relative to the first moving member 400, and the first moving member 400 is arranged with a motion track groove 440 along the motion track, and the connecting rod 930 rotates in the motion track groove 440 to limit the relative rotation range between the first moving member 400 and the second connecting part 900.

[0056] Please refer to the attached Figure 5 And attached Figure 6As shown, the self-detachable magnetic suction component 10 of the present application also includes a first sensor 200 and a second sensor 500. The first sensor 200 and the second sensor 500 are arranged at intervals along the first direction X. The first sensor 200 is electrically connected to the circuit board 300, and the first sensor 200 is fixedly arranged at the bottom of the circuit board 300 along the first direction X. The second sensor 500 is arranged on the side of the first moving part 400 facing the circuit board 300. The control element in the circuit board 300 is used to receive the detection signal of the first sensor 200, and further control the magnetic suction component 100 to have magnetic suction force or the magnetic suction force disappears according to the detection signal of the first sensor 200.

[0057] In one embodiment, the first sensor 200 is a position detection unit, and is used to detect the relative position relationship between the first sensor 200 and the second sensor 500. Further, the first sensor 200 is a Hall sensor element, and the second sensor 500 is a permanent magnet. When the second sensor 500 rotates synchronously with the first moving member 400, if the second sensor 500 is arranged corresponding to the first sensor 200, that is, the second sensor 500 is located directly below the first sensor 200, the magnetic field signal detected by the first sensor 200 is relatively strong. If the second sensor 500 is misaligned with the first sensor 200, that is, the second sensor 500 is not located directly below the first sensor 200, the magnetic field signal detected by the first sensor 200 is relatively weak, so that the relative position relationship between the first sensor 200 and the second sensor 500 is further determined by the magnetic field signal detected by the first sensor 200.

[0058] Among them, the first moving part 400 can form a relative movement with respect to the first sensor part 200, and further realize the relative movement of the first sensor part 200 with respect to the second sensor part 500. The self-separating magnetic suction component 10 forms a first movement state and a second movement state of the self-separating magnetic suction component 10 according to the relative movement relationship between the second sensor part 500 and the first sensor part 200. Among them, in the first movement state, the magnetic suction component 100 forms a magnetic suction force, and the magnetic suction component 100 is magnetically connected to the connection point 30. In the second movement state, the magnetic suction force in the magnetic suction component 100 disappears, and the magnetic suction component 100 is separated from the connection point 30. Therefore, a magnetic suction connection can be realized by switching between the first movement state and the second movement state, so as to facilitate the stable adsorption and easy picking between the self-separating magnetic suction component 10 and the connection point 30.

[0059] In one embodiment, the relative motion between the first moving member 400 and the first sensing member 200 is a circumferential rotational motion of the first moving member relative to the first sensing member 200. When the first moving member 400 is rotatably connected relative to the second connecting portion 900, the first sensing member 200 and the second sensing member 500 form a circumferential position change, and the first sensing member 200 is used to detect the relative position relationship between the first sensing member 200 and the second sensing member 500.

[0060] During the rotation of the first moving member 400 , the second sensor 500 on the first moving member 400 is misaligned relative to the first sensor 200 , and the self-detachable magnetic attraction assembly 10 is switched from the first moving state to the second moving state.

[0061] Please refer to the attached Figure 5 And attached Figure 6 As shown, the self-detachable magnetic suction component 10 of the present application also includes a reset member 920, which is used to restore the relative position relationship between the first sensor 200 and the second sensor 500 from a misaligned state to a corresponding state through the reset member 920 after the rotation of the first moving member 400 is canceled. When the second sensor 500 is arranged correspondingly to the first sensor 200, the self-detachable magnetic suction component 10 switches from the second motion state to the first motion state. Further, the reset member 920 also includes an elastic member 921 and a reset baffle 922, which are arranged along the rotation track of the first moving member 400, and the two ends of the elastic member 921 are respectively connected to the reset baffle 922 and the first moving member 400. When the first moving member 400 forms a relative rotation with respect to the second connecting portion 900, the elastic member 921 simultaneously forms a driving force to drive the first moving member 400 to return to an initial state, and the first moving member 400 is in the initial state, and the second sensor 500 is arranged corresponding to the first sensor 200. When the rotation of the first moving member 400 is canceled, the elastic member 921 drives the first moving member 400 to return to the initial state.
