[0050] To make the objectives, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0051] The prior art has the technical problem that the magnetic adsorption type control device is difficult to simultaneously meet the requirements of stable adsorption and convenient taking.

[0052] For this reason, on the one hand, the present application provides a self-separating magnetic adsorption component. The self-separating magnetic adsorption component is arranged in a connection main body. The connection main body is magnetically connectable to a junction to be connected through the self-separating magnetic adsorption component. It is characterized in that the self-separating magnetic adsorption component includes

[0053] A magnetic adsorption member, which is located in the connection main body and is magnetically connectable to the junction to be connected;

[0054] A first sensing member and a circuit board. The first sensing member is electrically connected to the magnetic adsorption member through the circuit board;

[0055] A first moving member, which is connected to the connection main body. A relative movement is formed between the first moving member and the first sensing member. The self-separating magnetic adsorption component forms a first movement state and a second movement state of the self-separating magnetic adsorption component according to the relative movement relationship between the first moving member and the first sensing member. Among them,

[0056] In the first movement state, the magnetic adsorption member forms a magnetic attraction force, and the magnetic adsorption member is magnetically connected to the junction to be connected;

[0057] In the second movement state, the magnetic attraction force in the magnetic adsorption member disappears, and the magnetic adsorption member is separated from the junction to be connected.

[0058] On the other hand, the present application provides a control device, which is characterized in that it includes the self-separating magnetic adsorption component described in Embodiment 1 or Embodiment 2 or Embodiment 3. The control device further includes

[0059] A connection main body, and the self-separating magnetic adsorption component is located in the connection main body.

[0060] Embodiment 1:

[0061] Please refer to the appendixFigure 1 to the attached Figure 2 As shown, a specific embodiment of the self-separating magnetic attraction component 10 of the present application is presented. In the prior art, the control device is magnetically connected to the connection point to be connected through the magnetic attraction component, and the strength of the magnetic attraction force in the magnetic attraction component is directly related to the fixing effect of the control device. How to appropriately select the strength of the magnetic attraction force in the magnetic attraction component so that the control device can be stably adsorbed and can be conveniently taken when it needs to be moved has always been a difficulty and pain point in the industry. That is, when the magnetic attraction force of the magnetic attraction component is too strong, although the control device can be stably adsorbed, when the control device needs to be moved, due to the too strong magnetic attraction force in the magnetic attraction component, it is very difficult for the control device to change its position. When the magnetic attraction force of the magnetic attraction component is too weak, although the control device can be relatively easily moved, there is a risk that the control device will fall off the connection point to be connected due to the weak magnetic attraction force of the magnetic attraction component. Further, in the present application, the self-separating magnetic attraction component 10 is installed in the movable knob, and the movable knob needs to switch different functions by changing the adsorption position. That is, when the knob with the self-separating magnetic attraction component 10 is placed on the car door, the window can be raised and lowered, and when the knob with the self-separating magnetic attraction component 10 is placed on one side of the seat, the seat can be adjusted. The self-separating magnetic attraction component 10 being arranged in the knob is only a specific embodiment of the present application, and the self-separating magnetic attraction component 10 can also be arranged in other devices that need magnetic attraction and need to be moved.

[0062] Please refer to the attached Figure 1 and the attached Figure 2 As shown, the first direction X of the present application refers to the height direction of the self-separating magnetic attraction component 10, that is, the direction from top to bottom or from bottom to top of the self-separating magnetic attraction component 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.

[0063] The attached Figure 1 is a schematic structural diagram of the self-separating magnetic attraction component 10 in the first motion state in Embodiment 1 of the present application. The attached Figure 2 is a schematic structural diagram of the self-separating magnetic attraction component 10 in the second motion state in Embodiment 1 of the present application. Please refer to the attached Figure 1 and the attached Figure 2 As shown, the self-separating magnetic attraction component 10 of the present application is used in combination with the connection main body 20, that is, the self-separating magnetic attraction component 10 is arranged in the connection main body 20 and magnetically connected to the connection point to be connected 30 as a part of the connection main body 20. The magnetically connectable connection means that the self-separating magnetic attraction component 10 has two states. One is that the self-separating magnetic attraction component 10 is magnetically connected to the connection point to be connected 30 when it has magnetic attraction force, and the other is that the self-separating magnetic attraction component 10 can be separated from the connection point to be connected 30 when it does not have magnetic attraction force.

[0064] Among them, the connection body 20 is a component for carrying the self-separating magnetic attraction assembly 10. In this application, the connection body 20 can be a control component for realizing the button function, and this control component can realize different functions by moving the adsorption position. Further, the connection body 20 includes a first connection portion 800. The first connection portion 800 is hollowly arranged. The first connection portion 800 is the main component of the connection body 20, and most of the structures in the self-separating magnetic attraction assembly 10 are arranged around the first connection portion 800. The connection body 20 further includes a connection panel 700. The connection panel 700 is located at the top of the first connection portion 800 along the first direction X. The connection panel 700 is fixedly connected to the first connection portion 800 and forms a covering for the hollow cavity in the first connection portion 800. The first connection portion 800 is for fixing other components, and a transverse connection structure 810 is horizontally arranged in its hollow cavity. The transverse connection structure 810 is fixedly connected to the first connection portion 800.

[0065] Among them, the to-be-connected portion 30 refers to the place where it is connected to the self-separating magnetic attraction assembly 10. There can be two or more to-be-connected portions 30. Therefore, the self-separating magnetic attraction assembly can be magnetically adsorbed at different to-be-connected portions 30 according to different needs. Further, the to-be-connected portion 30 can be different adsorption points in the vehicle. In one embodiment, the to-be-connected portion 30 includes a metal layer 32. The metal layer 32 is the main structure for realizing magnetic attraction with the self-separating magnetic attraction assembly 10. The to-be-connected portion 30 can further 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.

[0066] In one embodiment, the connection panel 700 and the first connection portion 800 are fixedly connected by means of buckles, glue, etc.

[0067] Please refer to the attached Figure 1 and the attached Figure 2 As shown, the self-separating magnetic attraction assembly 10 of this application includes a circuit board 300. Control elements are integrally arranged in the circuit board 300 of this application to switch between the first motion state and the second motion state back and forth according to the different relative positions between the first moving member 400 and the first sensing member 200. In this application, the circuit board 300 can also be used as an intermediate member to fix other components. Further, the circuit board 300 is horizontally arranged in the first connection portion 800, and the circuit board 300 is located on one side of the transverse connection structure 810. The circuit board 300 is fixedly connected to the transverse connection structure 810 through a first connecting member 310.

[0068] In one embodiment, the first connecting member 310 is a connecting bolt or a connecting buckle, etc.

[0069] Please refer to the attached Figure 1 and the attached Figure 2As shown, the self-separating magnetic attraction component 10 of the present application includes a magnetic attraction member 100. The magnetic attraction member 100 is the main component of the self-separating magnetic attraction component 10. The connecting body 20 is magnetically connected to the connection part to be connected 30 through the magnetic attraction member 100. The magnetic attraction member 100 is located inside the connecting body 20 and 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 force in the magnetic attraction member 100. The bottom of the magnetic attraction member 100 along the first direction X has a magnetic attraction surface, and the magnetic attraction surface in the magnetic attraction member 100 contacts the connection part to be connected to achieve magnetic attraction connection.

[0070] In one embodiment, the magnetic attraction member 100 is fixedly connected to the circuit board 300, and the magnetic attraction member 100 is located at the bottom of the circuit board 300 along the first direction X.

[0071] In one embodiment, the magnetic attraction member 100 is an energized demagnetization structure or an energized magnetization structure. The magnetic attraction member 100 of the energized demagnetization structure means that the magnetic attraction member 100 has a magnetic attraction force when not energized, and the magnetic attraction force disappears after the magnetic attraction member 100 is energized. The energized magnetization structure means that the magnetic attraction member 100 does not have a magnetic attraction force when not energized, and a magnetic attraction force appears after the magnetic attraction member 100 is energized. Further, the magnetic attraction member 100 of the present application is an energized demagnetization structure.

[0072] Please refer to the attached Figure 1 and the attached Figure 2 As shown, the self-separating magnetic attraction component 10 of the present application further includes a first sensing member 200. The first sensing member 200 is electrically connected to the circuit board 300, that is, the first sensing member 200 is electrically connected to the magnetic attraction member 100 through the circuit board 300. The control element in the circuit board 300 is used to receive the detection signal of the first sensing member 200 and further control the magnetic attraction member 100 to have a magnetic attraction force or the magnetic attraction force to disappear according to the detection signal of the first sensing member 200.

[0073] In one embodiment, the first sensing member 200 is a distance detection unit, and the first sensing member 200 is arranged at the bottom of the circuit board 300 along the first direction X.

[0074] Please refer to the attached Figure 1 and the attached Figure 2As shown in the figure. The self-separating magnetic attraction component 10 of the present application further includes a first moving member 400. The first moving member 400 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 arranged at the bottom of the first connecting portion 800 along the first direction X. The first moving member 400 is provided with a first through hole 430 penetrating along the first direction X. The first through hole 430 is located in the central area of the first moving member 400. The magnetic attraction surface of the magnetic attraction member 100 passes through the first through hole 430, and the magnetic attraction surface of the magnetic attraction member 100 is located outside the first through hole 430. The first moving member 400 further 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 the area of the first moving member 400 near the first through hole 430. The second area 420 is fixedly connected to the magnetic attraction member 100. The first area 410 is arranged at the edge of the first moving member 400, and the first area 410 is fixedly connected to the first connecting portion 800.

[0075] Further, the first moving member 400 can form a relative movement with respect to the first sensing member 200. The self-separating magnetic attraction component 10 forms a first movement state and a second movement state of the self-separating magnetic attraction component 10 according to the relative movement relationship between the first moving member 400 and the first sensing member 200. Among them, in the first movement state, the magnetic attraction member 100 forms a magnetic attraction force, and the magnetic attraction member 100 is magnetically connected to the connection-to-be 30. In the second movement state, the magnetic attraction force in the magnetic attraction member 100 disappears, and the magnetic attraction member 100 is separated from the connection-to-be 30. Therefore, the magnetically connectable connection can be realized by switching between the first movement state and the second movement state, so as to facilitate the stable adsorption and convenient taking between the self-separating magnetic attraction component 10 and the connection-to-be 30.

[0076] In an 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. And when the first moving member 400 moves up and down relative to the first sensing member 200 along the first direction X, a distance change in the first direction X is formed between the first moving member 400 and the first sensing member 200. 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 a flexible material. The flexible material in the present application refers to a flexible plastic or rubber. Further, there is a movement gap between the first connecting portion 800 and the first moving member 400, and there is also a movement gap between the circuit board 300 and the first connecting member 310. Therefore, the first moving member 400 can be deformed on the premise that the first sensing member 200 and the magnetic attraction member 100 do not move in the first direction X.

[0077] During the process of lifting the connection body 20, since the first region 410 in the first moving member 400 is connected to the connection body 20, and the second region 420 in the first moving member 400 is connected to the magnetic attracting 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 region 420 to the first region 410, that is, the first region 410 in the first moving member 400 is closer to the first sensing member 200 than the second region 420. And at this time, the corresponding region between the first sensing member 200 and the first moving member 400 is a partial region between the first region 410 and the second region 420. After the connection body 20 is lifted, the distance between this region and the first sensing member 200 is shortened simultaneously, and the first sensing member 200 can detect the distance between the first sensing member 200 and this region.

[0078] Among them, if the first sensing member 200 detects that the distance between the first sensing member 200 and the first moving member 400 continues to shorten, the first motion state of the self-separating magnetic attracting assembly 10 will be switched to the second motion state. The continuous shortening of the distance between the first sensing member 200 and the first moving member 400 refers to a process in which the distance between the first sensing member 200 and the first moving member 400 will continue to shorten after the connection body 20 is continuously lifted, so as to avoid mis-touch actions of the magnetic attracting member 100 being demagnetized when the distance between the first sensing member 200 and the first moving member 400 fluctuates due to bumps. If 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, the second motion state of the self-separating magnetic attracting assembly 10 will be switched to the first motion state. The first distance refers to the normal distance between the first sensing member 200 and the first moving member 400 when the connection body 20 is not lifted.

[0079] Please refer to the attached Figure 1 and the attached Figure 2 As shown, the self-separating magnetic attracting assembly 10 of the present application further includes a second sensing member 500. The second sensing member 500 is arranged on the first moving member 400. The second sensing member 500 and the first sensing member 200 are arranged corresponding to each other in the first direction X. When the first moving member 400 forms a relative motion with respect to the first sensing member 200, the second sensing member 500 simultaneously forms a relative motion with respect to the first sensing member 200 synchronously. The setting of the second sensing member 500 is to further detect the relative distance between the first sensing member 200 and the first moving member 400. In an embodiment, the first sensing member 200 is an infrared distance detection device, and the second sensing member 500 is used to reflect the infrared rays emitted by the first sensing member 200.

[0080] Please refer to the attached Figure 1 and the attached Figure 2As shown, the self-separating magnetic attraction component 10 of the present application further includes a first sensing member 600. The first sensing member 600 is provided to further prevent accidental touch. The first sensing member 600 is provided at the top of the connection body 20 along the first direction X. Under the trigger of the first sensing member 600, a switch is formed between the first motion state and the second motion state of the self-separating magnetic attraction component 10. Further, under the trigger of the first sensing member 600, and when the first sensing member 200 detects that the distance between the first sensing member 200 and the first moving member 400 continuously shortens, the self-separating magnetic attraction component 10 can switch the first motion state to the second motion state. Under the trigger of the first sensing member 600, when the first sensing member 200 detects that the distance between the first sensing member 200 and the first moving member 400 is a first distance, the self-separating magnetic attraction component 10 can switch the second motion state to the first motion state. Therefore, the setting of the first sensing member 600 can further avoid the occurrence of accidental touch behavior.

Appendix Figure 4 is a schematic structural diagram of the self-separating magnetic attraction component 10 in the second motion state in Embodiment 2 of the present application. Please refer to Appendix Figure 3 and Appendix Figure 4 As shown, the difference between the self-separating magnetic attraction component 10 in the present embodiment and the self-separating magnetic attraction component 10 in Embodiment 1 lies only in part of the structure of the connection body 20 and the setting positions of the first sensing member 200 and the first moving member 400. For the parts that are the same in Embodiment 2 and Embodiment 1, please refer to the description of Embodiment 1, and Embodiment 2 will not be elaborated.

[0083] Please refer to Appendix Figure 3 and Appendix Figure 4 As shown, the self-separating magnetic attraction component 10 of the present application is used in combination with the connection body 20, that is, the self-separating magnetic attraction component 10 is arranged in the connection body 20 and magnetically connectable to the connection part 30 as a part of the connection body 20. The magnetically connectable connection means that the self-separating magnetic attraction component 10 has two states. One is that the self-separating magnetic attraction component 10 is magnetically connected to the connection part 30 when it has magnetic attraction, and the other is that the self-separating magnetic attraction component 10 can be separated from the connection part 30 when it does not have magnetic attraction.

[0084] Among them, the connection body 20 is a component for carrying the self-separating magnetic attraction assembly 10. In this application, the connection body 20 can be a control component for realizing the button function, and this control component can realize different functions by moving the adsorption position. Further, the connection body 20 includes a first connection portion 800. The first connection portion 800 is hollowly arranged. The first connection portion 800 is the main component of the connection body 20. Most of the structures in the self-separating magnetic attraction assembly 10 are arranged around the first connection portion 800. The bottom surface of the first connection portion 800 is flush with the magnetic attraction surface of the magnetic attraction member 100. The connection body 20 further includes a connection panel 700. The connection panel 700 is located at the top of the first connection portion 800 along the first direction X. The connection panel 700 is fixedly connected to the first connection portion 800 and forms a covering for the hollow cavity inside the first connection portion 800. Further, the connection panel 700 is provided with a second through hole along the first direction X. The second through hole is used to realize the installation of the first moving member 400.

[0085] Please refer to the attached Figure 3 and the attached Figure 4 As shown, the self-separating magnetic attraction assembly 10 of this application further includes a first sensing member 200. The first sensing member 200 is electrically connected to the circuit board 300, that is, the first sensing member 200 is electrically connected to the magnetic attraction member 100 through the circuit board 300. The control element in the circuit board 300 is used to receive the detection signal of the first sensing member 200 and further control the magnetic attraction member 100 to have magnetic attraction force or the magnetic attraction force disappears according to the detection signal of the first sensing member 200.

[0086] In an embodiment, the first sensing member 200 is a distance detection unit. The first sensing member 200 is arranged at the top of the circuit board 300 along the first direction X.

[0087] Please refer to the attached Figure 3 and the attached Figure 4As shown, the self-separating magnetic attraction component 10 of the present application further includes a first moving member 400. The first moving member 400 is connected to the connection main body 20, and the first moving member 400 is disposed on the top of the connection main body 20 along the first direction X. Further, the first moving member 400 is disposed in the second through hole of the connection panel 700, and the first moving member 400 is connected to the inner wall of the second through hole. The first moving member 400 can form a relative movement with respect to the first sensing member 200. The self-separating magnetic attraction component 10 forms a first movement state and a second movement state of the self-separating magnetic attraction component 10 according to the relative movement relationship between the first moving member 400 and the first sensing member 200. Among them, in the first movement state, the magnetic attraction member 100 forms a magnetic attraction force, and the magnetic attraction member 100 is magnetically connected to the connection to be made 30. In the second movement state, the magnetic attraction force in the magnetic attraction member 100 disappears, and the magnetic attraction member 100 is separated from the connection to be made 30. Therefore, the magnetically connectable connection can be realized by switching between the first movement state and the second movement state, so as to facilitate the stable adsorption and convenient taking between the self-separating magnetic attraction component 10 and the connection to be made 30.

[0088] 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. And when the first moving member 400 moves up and down relative to the first sensing member 200 along the first direction X, a distance change in the first direction X is formed between the first moving member 400 and the first sensing member 200. 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, and the elastic material in the present application refers to plastic or rubber with elasticity.

[0089] During the process of pressing down the first moving member 400, the first moving member 400 forms a depression downward, and the distance between the first moving member 400 and the first sensing member 200 is shortened at the same time, and the first sensing member 200 can detect the distance between the first sensing member 200 and the first moving member 400. When the pressing on the first moving member 400 is cancelled, the first moving member 400 rebounds upward and returns to the normal state. The distance between the first moving member 400 and the first sensing member 200 in the normal state is the first distance.

[0090] Among them, if the first sensing component 200 detects that the distance between the first sensing component 200 and the first moving component 400 continuously shortens, the first motion state of the self-separating magnetic attraction component 10 will be switched to the second motion state. The continuous shortening of the distance between the first sensing component 200 and the first moving component 400 means that during the process of continuously pressing down the first moving component 400, there will be a process of continuous shortening of the distance between the first sensing component 200 and the first moving component 400, so as to avoid mis-touch actions of demagnetization of the magnetic attraction component 100 when the distance between the first sensing component 200 and the first moving component 400 fluctuates under bumpy conditions. If the first sensing component 200 detects that the distance between the first sensing component 200 and the first moving component 400 is the first distance, the second motion state of the self-separating magnetic attraction component 10 will be switched to the first motion state. The first distance refers to the normal distance between the first sensing component 200 and the first moving component 400 when the first moving component 400 is not pressed down.

[0092] Appendix Figure 5 is a schematic structural diagram of the self-separating magnetic attraction component 10 in Embodiment 3 of the present application. Appendix Figure 6 is a schematic structural diagram between the connection main body 20 and the first moving component 400 in Embodiment 3 of the present application. Please refer to Appendix Figure 5 and Appendix Figure 6 As shown, the difference between the self-separating magnetic attraction component 10 in this embodiment and the self-separating magnetic attraction component 10 in Embodiment 1 lies only in some structures of the connection main body 20 and the setting positions of the first sensing component 200 and the first moving component 400. For the same parts in Embodiment 3 and Embodiment 1, please refer to the description of Embodiment 1, and Embodiment 3 will not be described in detail.

[0093] Please refer to Appendix Figure 5 and Appendix Figure 6 As shown, the self-separating magnetic attraction component 10 of the present application is used in combination with the connection main body 20, that is, the self-separating magnetic attraction component 10 is arranged in the connection main body 20 and magnetically connectable to the connection part 30 as a part of the connection main body 20. The magnetically connectable connection means that the self-separating magnetic attraction component 10 has two states. One is that the self-separating magnetic attraction component 10 is magnetically connected to the connection part 30 when it has magnetic attraction, and the other is that the self-separating magnetic attraction component 10 can be separated from the connection part 30 when it does not have magnetic attraction.

[0094] Among them, the connection body 20 is a component for carrying the self-separating magnetic attraction assembly 10. In this application, the connection body 20 can be a control component for realizing the button function, and this control component can realize different functions by moving the adsorption position. Further, the connection body 20 includes a first connection part 800 and a second connection part 900 that are sequentially arranged at intervals along the first direction X. The second connection part 900 is located at the bottom of the first connection part 800 along the first direction X. A connecting rod 930 extends along the first direction X on the side of the second connection part 900 facing the first connection part 800. The connecting rod 930 is connected to the first connection part 800 through a second connecting piece 910. And the bottom surface of the second connection part 900 along the first direction X is flush with the magnetic attraction surface of the magnetic attraction piece 100.

[0095] In one embodiment, the second connecting piece 910 is a buckle structure, and the second connecting piece 910 is in a buckle connection with both the first connection part 800 and the second connection part 900.

[0096] Please refer to the attached Figure 5 and the attached Figure 6 As shown, the self-separating magnetic attraction assembly 10 of this application further includes a first moving part 400. The first moving part 400 is connected to the connection body 20, and the first moving part 400 is arranged at the bottom of the connection body 20 along the first direction X. Further, the first moving part 400 semi-wraps the second connection part 900, and the first moving part 400 is rotatably connected to the second connection part 900. The side surface of the first moving part 400 is exposed outside the connection body 20, and the relative rotation between the first moving part 400 and the second connection part 900 is realized by driving the side surface of the first moving part 400. The connecting rod 930 extends upward along the first direction X and passes through the first moving part 400. When the second connection part 900 rotates relative to the first moving part 400, the connecting rod 930 forms a movement track relative to the first moving part 400. The first moving part 400 is provided with a movement track groove 440 along the movement track. The connecting rod 930 rotates in the movement track groove 440 to limit the relative rotation range between the first moving part 400 and the second connection part 900.

[0097] Please refer to the attached Figure 5 and the attached Figure 6 As shown, the self-separating magnetic attraction assembly 10 of this application further includes a first sensing part 200 and a second sensing part 500. The first sensing part 200 and the second sensing part 500 are arranged at intervals along the first direction X. The first sensing part 200 is electrically connected to the circuit board 300, and the first sensing part 200 is fixedly arranged at the bottom of the circuit board 300 along the first direction X. The second sensing part 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 sensing part 200 and further control the magnetic attraction piece 100 to have magnetic attraction or the magnetic attraction disappears according to the detection signal of the first sensing part 200.

[0098] In one embodiment, the first sensing member 200 is a position detection unit and is used to detect the relative position relationship between the first sensing member 200 and the second sensing member 500. Further, the first sensing member 200 is a Hall sensing element, and the second sensing member 500 is a permanent magnet. When the second sensing member 500 rotates synchronously with the first moving member 400, if the second sensing member 500 is correspondingly arranged with the first sensing member 200, that is, the second sensing member 500 is directly below the first sensing member 200, the magnetic field signal detected by the first sensing member 200 is relatively strong. If the second sensing member 500 is misaligned with the first sensing member 200, that is, the second sensing member 500 is not directly below the first sensing member 200, the magnetic field signal detected by the first sensing member 200 is relatively weak. Thus, the relative position relationship between the first sensing member 200 and the second sensing member 500 is further determined by the magnetic field signal detected by the first sensing member 200.

[0099] Wherein, the first moving member 400 can form a relative movement with respect to the first sensing member 200, and further realize the relative movement of the first sensing member 200 with respect to the second sensing member 500. The self-separating magnetic attraction assembly 10 forms a first motion state and a second motion state of the self-separating magnetic attraction assembly 10 according to the relative movement relationship between the second sensing member 500 and the first sensing member 200. Among them, in the first motion state, the magnetic attraction member 100 forms a magnetic attraction force, and the magnetic attraction member 100 is magnetically connected to the connection-to-be 30 in a magnetic attraction manner. In the second motion state, the magnetic attraction force in the magnetic attraction member 100 disappears, and the magnetic attraction member 100 is separated from the connection-to-be 30. Therefore, the magnetically connectable connection can be realized by switching between the first motion state and the second motion state, so as to facilitate the stable adsorption between the self-separating magnetic attraction assembly 10 and the connection-to-be 30 and the convenient taking.

[0100] In one embodiment, the relative movement between the first moving member 400 and the first sensing member 200 is the circumferential rotational movement of the first moving member relative to the first sensing member 200. And when the first moving member 400 is rotationally connected with respect 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.

[0101] During the rotation of the first moving member 400, if the second sensing member 500 on the first moving member 400 is misaligned with respect to the first sensing member 200, the self-separating magnetic attraction assembly 10 is switched from the first motion state to the second motion state.

[0102] Please refer to the appendix Figure 5 and the appendix Figure 6As shown in the figure, the self-separating magnetic attraction assembly 10 of the present application further includes a reset member 920. The reset member 920 is used to restore the relative position relationship between the first sensing member 200 and the second sensing member 500 from the misaligned state to the corresponding state by the reset member 920 after canceling the rotation of the first moving member 400. When the second sensing member 500 and the first sensing member 200 are correspondingly arranged, the self-separating magnetic attraction assembly 10 switches from the second motion state to the first motion state. Further, the reset member 920 further includes an elastic member 921 and a reset baffle 922. The elastic member 921 and the reset baffle 922 are arranged along the rotation trajectory of the first moving member 400. Both ends of the elastic member 921 are connected to the reset baffle 922 and the first moving member 400 respectively. 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 for driving the first moving member 400 to return to the initial state. In the initial state of the first moving member 400, the second sensing member 500 and the first sensing member 200 are correspondingly arranged. 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.
