Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The existing technology of Hall effect sensing devices based on dual-magnet differential structures has a technical problem: the top magnet in the device is prone to adsorption of other substances, which affects its performance.

[0031] Therefore, this application provides a motion recognition component, wherein the motion recognition component includes,

[0032] A first magnetic element, the first magnetic element having magnetism, the first magnetic element being arranged along a first motion trajectory;

[0033] A first metal component, made of metal material, is arranged along the first motion trajectory, and can move relative to the first magnetic component along the first motion trajectory. A magnetic field is formed between the first magnetic component and the first metal component.

[0034] A Hall effect sensor and a circuit board are included. The circuit board is located between the first magnetic component and the first metal component. The Hall effect sensor is connected to the circuit board and is correspondingly arranged with the first magnetic component. The Hall effect sensor is arranged on the first motion trajectory and is used to detect the positional relationship between the first magnetic component and the first metal component. Under the movement of the first metal component, the motion recognition component forms a first state and a second state.

[0035] In the first state, the Hall sensor is configured correspondingly to the first metal component;

[0036] In the second state, the Hall sensor is misaligned with the first metal component, and the magnetic field strength detected by the Hall sensor in the first state is greater than the magnetic field strength detected by the Hall sensor in the second state.

[0037] This application also provides a movable control device, wherein the movable control device includes the motion recognition component described in Embodiment 1, and the movable control device further includes...

[0038] A first connecting part, wherein the first magnetic element is located inside the first connecting part, and the first connecting part is magnetically connected to the part to be connected through the first magnetic element;

[0039] The second connecting part is located inside the first metal part. The first metal part moves synchronously with the second connecting part, and the second connecting part moves and connects with the first connecting part along the first movement trajectory.

[0040] Example 1:

[0041] Please refer to the attached document. Figure 1 The diagram illustrates a specific embodiment of the motion identification component of this application. In the prior art, Hall sensors are magnetoelectric conversion elements made using the Hall effect, and Hall sensing devices can be fabricated from Hall sensors. A common form is the dual-magnet differential structure Hall sensing device. This dual-magnet differential structure refers to a structure where two magnets (with the same N pole or opposite poles) are symmetrically placed on both sides of the Hall sensor, forming a uniform magnetic field. The Hall sensor uses a differential circuit to detect changes in the difference between the magnetic fields on both sides to output control commands. Dual-magnet differential Hall sensing devices are typically used within control devices. However, the magnet located at the top of the control device easily attracts other substances. Since the control device of this application typically uses a movable adsorption method, the presence of other substances adsorbed on the control device can easily affect its operation.

[0042] Appendix Figure 1 This is a schematic diagram of one possible structure of the movable controllable device of this application. Please refer to the attached diagram. Figure 1 As shown, the first direction X in this application refers to the height direction of the movable control device, that is, the direction from top to bottom or from bottom to top of the movable control device. In this application, the first connecting portion is disposed lower than the second connecting portion, and the second connecting portion is disposed higher than the first connecting portion.

[0043] Please refer to the attached document. Figure 1 As shown, the motion identification component of this application is typically installed within a movable control device for use. This embodiment only describes the motion identification component. The motion identification component of this application includes a first magnetic element 300, which is magnetic. The first magnetic element 300 is positioned along a first motion trajectory. In this embodiment, the first motion trajectory is the trajectory formed by the rotation or translation of the first metal element 400 relative to the first magnetic element 300. The first motion trajectory does not have an actual shape in this application; it is only established to further describe other components in the motion identification component. The first motion trajectory is positioned along the first motion trajectory to facilitate the Hall sensor 500 in identifying the relative position between the first magnetic element 300 and the first metal element 400 by judging the magnetic field strength.

[0044] In one implementation, the first magnetic component 300 is made of a magnet.

[0045] Please refer to the attached document. Figure 1 As shown, the mobile identification component of this application also includes a first metal part 400. The first metal part 400 is made of metal material and is set along a first motion trajectory. The first metal part 400 can move relative to the first magnetic part 300 along the first motion trajectory. A magnetic field is formed between the first metal part 400 and the first magnetic part 300. In specific use, the first metal part 400 is located at the top of the first magnetic part 300 along the first direction X.

[0046] In one embodiment, to create a tactile feedback during the movement of the first metal component 400, when the first movement trajectory is circular, the first magnetic component 300 and the first metal component 400 are spaced apart circumferentially along the first movement trajectory. As the first metal component 400 rotates, the first magnetic component 300 and the first metal component 400 switch between strong and weak connections, creating a tactile feedback between them, further enhancing the rotational feel of the motion recognition component.

[0047] When the first motion trajectory is linear, the first magnetic component 300 and the first metal component 400 are arranged at a linear interval along the first motion trajectory. As the first metal component 400 is translated, the first magnetic component 300 and the first metal component 400 switch between strong and weak connections, creating a tactile feedback between them, which further enhances the tactile feel of the motion recognition component.

[0048] Furthermore, the switching between strong and weak connections between the first magnetic component 300 and the first metal component 400 refers to the fact that, with the rotation of the first metal component 400, the movable identification component forms a first state and a second state, and can switch between the first state and the second state. In the first state, the first metal component 400 and the first magnetic component 300 are correspondingly arranged, and a strong connection is formed between them. In the second state, the first metal component 400 and the first magnetic component 300 are misaligned, and a weak connection is formed between them. Furthermore, the magnetic field strength between the first magnetic component 300 and the first metal component 400 in the first state is greater than the magnetic field strength between them in the second state.

[0049] In one embodiment, the relative motion relationship between the first metal component 400 and the first magnetic component 300 includes rotational connection and translational connection. When the first metal component 400 and the first magnetic component 300 are rotationally connected, the first motion trajectory is circular. When the first metal component 400 and the first magnetic component 300 are translationally connected, the first motion trajectory is linear.

[0050] Please refer to the attached document. Figure 1 As shown, the motion recognition component of this application also includes a Hall sensor 500. The Hall sensor 500 is used to identify the positional relationship between the first magnetic component 300 and the first metal component 400. When the Hall sensor 500 detects a change in the strength of the magnetic field between the first magnetic component 300 and the first metal component 400, the motion recognition component synchronously executes a control command. The Hall sensor 500 is connected to the circuit board 600. Here, "Hall sensor 500 connected to circuit" means that the Hall sensor 500 is electrically connected to the circuit board 600. The Hall sensor 500 is correspondingly arranged with the first magnetic component 300 and is arranged on the first motion trajectory. In specific use, the Hall sensor 500 is used to send the detected magnetic field strength to the circuit board 600, and the circuit board 600 converts the change in magnetic field strength detected by the Hall sensor 500 into a control command. The Hall sensor 500 is used to detect the strength of the magnetic field between the first magnetic element 300 and the first metal element 400. In this application, there is no difference in the magnetic field strength between the first magnetic element 300 and the first metal element 400. The first metal element 400 moves relative to the first magnetic element 300 and the Hall sensor 500. When the relative position between the Hall sensor 500 and the first metal element 400 is different, the magnetic field strength detected by the Hall sensor 500 is different.

[0051] When the first metal component 400 moves, the Hall sensor 500 and the first magnetic component 300 remain stationary. The first metal component 400 and the first magnetic component 300 form a corresponding or misaligned positional relationship, thus enabling the movement identification component to reach its first and second states. In the first state, the Hall sensor 500 and the first metal component 400 are correspondingly positioned, with the Hall sensor 500 located between the first magnetic component 300 and the first metal component 400. In the second state, the Hall sensor 500 and the first metal component 400 are misaligned, and the magnetic field strength detected by the Hall sensor 500 in the first state is greater than that detected in the second state.

[0052] In one embodiment, the Hall sensor 500 is fixedly connected to the circuit board 600, and the circuit board 600 having the Hall sensor 500 is located between the first magnetic element 300 and the first metal element 400.

[0053] In one embodiment, two or more Hall effect sensors 500 are provided, arranged side-by-side on a circuit board 600. Further, two Hall effect sensors 500 are provided, arranged on the circuit board 600. Initially, both Hall effect sensors 500 correspond to two side-by-side first metal elements 400, and both Hall effect sensors 500 detect a strong magnetic field. When the first metal element 400 rotates, one of the Hall effect sensors 500 first misaligns with the first metal element 400. By knowing which Hall effect sensor 500 misaligns with the first metal element 400 first, the rotation direction of the first metal element 400 can be determined. Further, if multiple sets of first magnetic elements 300 and first metal elements 400 are provided, the rotation angle of the first metal element 400 can be further determined.

[0054] Example 2:

[0055] Appendix Figure 1 This is a schematic diagram of one possible structure of the movable control device 10 of this application. Please refer to the attached diagram. Figure 1 As shown, the first direction X in this application refers to the height direction of the movable control device 10, that is, the direction of the movable control device 10 from top to bottom or from bottom to top. In this application, the first connecting portion 100 is disposed lower than the second connecting portion 200, and the second connecting portion 200 is disposed higher than the first connecting portion 100.

[0056] Please refer to the attached document. Figure 1As shown, the movable control device 10 of this application includes a first connecting part 100 and a second connecting part 200. The first connecting part 100 and the second connecting part 200 are arranged sequentially along a first direction X. The first connecting part 100 is located at the bottom of the second connecting part 200 along the first direction X. The first connecting part 100 and the second connecting part 200 are movably connected. Through the relative movement of the first connecting part 100 and the second connecting part 200, the movable control device 10 can issue control commands.

[0057] Please refer to the attached document. Figure 1 As shown, the first connecting portion 100 of this application is detachably connected to the part to be connected, so as to facilitate the installation of the movable control device 10 in various positions inside the vehicle. When the movable control device 10 is installed in different positions, the control commands it can execute are also different. Furthermore, the second connecting portion 200 can move relative to the first connecting portion 100 along a first motion trajectory. The first motion trajectory refers to the trajectory formed by the rotation or translation of the second connecting portion 200 relative to the first connecting portion 100. The first motion trajectory does not have an actual shape in this application, but is only set up to further describe other components in the movable control device 10.

[0058] In one embodiment, the relative motion relationship between the first connecting portion 100 and the second connecting portion 200 includes rotational connection and translational connection. When the first connecting portion 100 and the second connecting portion 200 are rotatably connected, the first motion trajectory is circular, and the movable control device 10 of this application is a knob. When the first connecting portion 100 and the second connecting portion 200 are translationally connected, the first motion trajectory is linear, and the movable control device 10 of this application is a translational button.

[0059] Please refer to the attached document. Figure 1The movable control device 10 of this application includes a first magnetic element 300. The first magnetic element 300 is disposed within the first connecting portion 100 along a first motion trajectory. When the first magnetic element 300 is disposed within the first connecting portion 100 along the first motion trajectory, it facilitates the Hall sensor 500 to identify the relative position between the first magnetic element 300 and the first metal element 400 by judging the magnetic field strength. The first connecting portion 100 is magnetically connected to the point to be connected via the first magnetic element 300, thereby further realizing the detachable connection between the first connecting portion 100 and the point to be connected. In this application, the point to be connected can be any location within the vehicle's driver's compartment. In this application, the first magnetic element 300 not only realizes the magnetic connection of the movable control device 10, but also works with the first metal element 400 to create a magnetic field, further enabling the Hall sensor 500 to make identification and judgment. Compared with the prior art, the first magnetic component 300 of this application can realize magnetic connection and control judgment of the movable control device 10 at the same time, which reduces the use of magnetic components in the movable control device 10 of this application, and optimizes the internal structure of the movable control device 10 while reducing costs.

[0060] Please refer to the attached document. Figure 1 As shown, the movable control device 10 of this application also includes a first metal component 400. The first metal component 400 is disposed within the second connecting portion 200 along a first motion trajectory to further prevent the second connecting portion 200 from adsorbing with other substances, thereby improving the user experience of the movable control device 10. When the second connecting portion 200 rotates, the first metal component 400 moves synchronously with the second connecting portion 200. At this time, the first metal component 400 moves along the first motion trajectory, and a magnetic field is formed between the first magnetic component 300 and the first metal component 400.

[0061] In one implementation, to provide a tactile feedback during the movement of the second connecting portion 200, when the first movement trajectory is circular, the first magnetic component 300 and the first metal component 400 are spaced apart circumferentially along the first movement trajectory. As the second connecting portion 200 rotates, the first magnetic component 300 and the first metal component 400 switch between strong and weak connections, creating a tactile feedback between the first connecting portion 100 and the second connecting portion 200, further enhancing the tactile feedback of the movable control device 10.

[0062] When the first motion trajectory is linear, the first magnetic component 300 and the first metal component 400 are arranged at intervals along the first motion trajectory. Under the translation of the second connecting part 200, the first magnetic component 300 and the first metal component 400 switch between strong connection and weak connection, and form a tactile feedback between the first connecting part 100 and the second connecting part 200, so as to further form the rotational feel of the movable control device 10.

[0063] Furthermore, the switching between strong and weak connection between the first magnetic component 300 and the first metal component 400 refers to the fact that, under the rotation of the second connecting part 200, the movable control device 10 forms a first state and a second state, and switches between the first state and the second state. In the first state, the first metal component 400 and the first magnetic component 300 are correspondingly arranged, and a strong connection is formed between them. In the second state, the first metal component 400 and the first magnetic component 300 are misaligned, and a weak connection is formed between them. Furthermore, the magnetic field strength between the first magnetic component 300 and the first metal component 400 in the first state is greater than the magnetic field strength between them in the second state.

[0064] Please refer to the attached document. Figure 1 As shown, the movable control device 10 of this application also includes a Hall sensor 500. The Hall sensor 500 is used to identify the positional relationship between the first magnetic element 300 and the first metal element 400. When the Hall sensor 500 detects a change in the strength of the magnetic field between the first magnetic element 300 and the first metal element 400, the movable control device 10 synchronously executes the control command. The Hall sensor 500 is connected to the circuit board 600. Here, the connection between the Hall sensor 500 and the circuit board 600 refers to an electrical connection between the Hall sensor 500 and the circuit board 600. The first metal element 400 and the second connecting part 200 move synchronously. The Hall sensor 500 is correspondingly arranged with the first magnetic element 300 and is arranged on the first motion trajectory. In specific use, the Hall sensor 500 is used to send the detected magnetic field strength to the circuit board 600, and the circuit board 600 converts the change in magnetic field strength detected by the Hall sensor 500 into a control command. The Hall sensor 500 is used to detect the strength of the magnetic field between the first magnetic component 300 and the first metal component 400. In this application, there is no difference in the magnetic field strength between the first magnetic component 300 and the first metal component 400. However, the second connecting part 200 drives the first metal component 400 to move relative to the first magnetic component 300 and the Hall sensor 500 during the movement. When the relative position between the Hall sensor 500 and the first metal component 400 is different, the magnetic field strength detected by the Hall sensor 500 is different.

[0065] When the second connecting part 200 moves, the first metal part 400 moves synchronously, while the Hall sensor 500 and the first magnetic part 300 remain stationary. The first metal part 400 and the first magnetic part 300 form a corresponding or misaligned positional relationship, thus enabling the movement of the control device 10 to its first and second states. In the first state, the Hall sensor 500 and the first metal part 400 are correspondingly positioned, with the Hall sensor 500 located between the first magnetic part 300 and the first metal part 400. In the second state, the Hall sensor 500 and the first metal part 400 are misaligned, and the magnetic field strength detected by the Hall sensor 500 in the first state is greater than that detected in the second state.

[0066] In one embodiment, the Hall sensor 500 is fixedly connected to the circuit board 600, and the circuit board 600 having the Hall sensor 500 is located between the first magnetic element 300 and the first metal element 400.

[0067] In one embodiment, to further distinguish the rotation direction and rotation angle of the second connecting portion 200 relative to the first connecting portion 100, two or more Hall sensors 500 are provided, arranged side-by-side on the circuit board 600. Further, two Hall sensors 500 are provided, arranged on the circuit board 600. Initially, both Hall sensors 500 correspond to two side-by-side first metal parts 400, and both Hall sensors 500 detect a strong magnetic field. When the second connecting portion 200 rotates, one of the Hall sensors 500 first misaligns with the first metal part 400. By knowing which Hall sensor 500 first misaligns with the first metal part 400, the rotation direction of the second connecting portion 200 can be determined. Further, if multiple sets of first magnetic parts 300 and first metal parts 400 are provided, the rotation angle of the second connecting portion 200 can be further determined.
