Description

Technical Field

[0001] This application relates to the field of robotics technology, specifically to a battery assembly and a robot. Background Technology

[0002] The robot's battery is typically removably mounted on the robot and locked in place by a locking mechanism to maintain its position. When the battery is depleted, the locking mechanism can be unlocked to allow for battery replacement.

[0003] In related technologies, the locking mechanism used to lock and unlock the battery has a relatively complex structure, which makes battery removal inconvenient. Summary of the Invention

[0004] Embodiments of this application provide a battery assembly and a robot that can improve the technical problem that the complex structure used for locking and unlocking the battery in the battery assembly makes battery disassembly inconvenient.

[0005] In a first aspect, embodiments of this application provide a battery assembly, comprising:

[0006] Battery compartment, including mounting cavity;

[0007] A battery, which is detachably installed in the mounting cavity;

[0008] A locking structure is movably connected to the battery compartment. During the movement of the locking structure relative to the battery compartment, there are at least a locked position and an unlocked position. When the locking structure is in the locked position, it can contact the battery to prevent the battery from being dislodged from the battery compartment. When the locking structure is in the unlocked position, it is separated from the battery. The locking structure includes a first magnetic element.

[0009] The movable structure includes a movable member and a second magnetic member mounted on the battery. When the battery is mounted in the mounting cavity, the movable member is used to drive the second magnetic member to move relative to the first magnetic member.

[0010] In some embodiments, the battery compartment is provided with an elastic element connected to the locking structure, the elastic element being used to drive the locking structure from the locked position to the unlocked position;

[0011] When the battery is installed in the mounting cavity, the movable member is used to drive the second magnetic member away from the first magnetic member, so that the elastic member drives the first magnetic member to move the locking structure from the locked position to the unlocked position.

[0012] In some embodiments, the movable member is further used to drive the second magnetic member closer to the first magnetic member, so that the first magnetic member drives the locking structure to move from the unlocked position to the locked position.

[0013] In some embodiments, the second magnetic element is slidably connected to the battery, and the movable element is used to drive the second magnetic element to slide relative to the battery, so that the second magnetic element moves closer to or away from the first magnetic element.

[0014] In some embodiments, the sliding direction of the second magnetic element relative to the battery forms an angle with the direction in which the battery is inserted into the mounting cavity; when the battery is installed in the mounting cavity, the locking structure is located on one side of the battery along the sliding direction of the second magnetic element.

[0015] In some embodiments, the battery compartment is provided with the locking structure on both sides along the sliding direction of the second magnetic element; the movable element is a strip-shaped structure extending along the sliding direction of the second magnetic element, and the two ends of the movable element are respectively connected to different second magnetic elements.

[0016] In some embodiments, the movable structure is located on one side of the battery along the direction of exiting the mounting cavity.

[0017] In some embodiments, the battery includes a cover plate and a housing connected sequentially along the direction in which the battery is inserted into the mounting cavity, a groove is formed between the housing and the cover plate, and the second magnetic element is slidably mounted in the groove;

[0018] The cover plate has a through hole that extends through the cover plate in the direction in which the battery exits the mounting cavity, and a portion of the movable component can be exposed through the through hole.

[0019] In some embodiments, the movable structure includes a connector connected to the movable member, the connector being slidably mounted in the groove, and the second magnetic member being connected to the connector.

[0020] In some embodiments, the battery includes a limiting portion for contacting the connector to limit the distance by which the connector can move the second magnetic element away from the first magnetic element.

[0021] In some embodiments, the locking structure includes a locking part, the battery includes an abutment part, and when the locking structure is in the locked position, the locking part is located on the side of the abutment part away from the mounting cavity, and the locking part is used to abut against the abutment part to lock the battery;

[0022] When the locking structure is in the unlocked position, the locking part avoids the abutting part to unlock the battery.

[0023] In some embodiments, the locking structure is rotatably connected to the battery compartment, and the locking structure is rotatable relative to the battery compartment between the locked position and the unlocked position.

[0024] Secondly, embodiments of this application provide a robot including the battery assembly described above, the battery assembly comprising:

[0025] Battery compartment, including mounting cavity;

[0026] A battery, which is detachably installed in the mounting cavity;

[0027] A locking structure is movably connected to the battery compartment. During the movement of the locking structure relative to the battery compartment, there are at least a locked position and an unlocked position. When the locking structure is in the locked position, it can contact the battery to prevent the battery from being dislodged from the battery compartment. When the locking structure is in the unlocked position, it is separated from the battery. The locking structure includes a first magnetic element.

[0028] The movable structure includes a movable member and a second magnetic member mounted on the battery. When the battery is mounted in the mounting cavity, the movable member is used to drive the second magnetic member to move relative to the first magnetic member.

[0029] The beneficial effects of the embodiments of this application are as follows:

[0030] The battery assembly provided in this application embodiment detachably installs the battery in the mounting cavity of the battery compartment. By movably connecting the locking structure to the battery compartment, the movable member and the second magnetic member of the movable structure are installed on the battery. When the battery is installed in the mounting cavity of the battery compartment, the movable member drives the second magnetic member to move relative to the first magnetic member, thereby adjusting the magnetic force between the first magnetic member and the second magnetic member. This allows the first magnetic member to drive the locking structure from the locked position that restricts the battery from detaching from the battery compartment to the unlocked position that separates from the battery, so that the battery can be removed from the battery compartment.

[0031] The movable and locking structures are relatively simple. By adjusting the magnetic force between the first and second magnetic components through the movable component, the first magnetic component drives the locking structure to unlock the battery, making it easy to remove the battery from the battery compartment.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the 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. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0044] This application provides a battery assembly and a robot.

[0045] Figure 1 This is a schematic diagram of the structure of one embodiment of the battery assembly provided in this application. Figure 4 This is an exploded structural diagram of one embodiment of the battery assembly provided in this application. Figure 1 and Figure 4 As shown, the battery assembly 1 includes a battery compartment 10 and a battery 20. The battery compartment 10 includes a mounting cavity 100, and the battery 20 is detachably mounted in the mounting cavity 100. The battery assembly 1 can be used in a robot. The robot includes a robot body, and the battery compartment 10 is mounted on the robot body. By detachably mounting the battery 20 in the mounting cavity 100 of the battery compartment 10, the battery 20 supplies power to the robot body. When the battery 20 is depleted, it can be removed from the mounting cavity 100 of the battery compartment 10 for replacement. Of course, the battery assembly 1 in this embodiment can also be used in other electrical devices, and this is not a limitation.

[0046] It should be noted that when the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the battery 20 can be fully accommodated in the mounting cavity 100 of the battery compartment 10, or a portion of the battery 20 can be accommodated in the mounting cavity 100 of the battery compartment 10. No limitation is made here.

[0047] In some embodiments, as Figure 2 and Figure 3 , Figure 6 and Figure 7 As shown, the battery assembly 1 may further include a locking structure 30, which is movably connected to the battery compartment 10. During its movement relative to the battery compartment 10, the locking structure 30 has at least a locked position and an unlocked position. Figure 2 and Figure 3As shown, when the locking structure 30 is in the locked position, it can contact the battery 20 to prevent the battery 20 from detaching from the battery compartment 10. Figure 6 and Figure 7 As shown, the locking structure 30 is separated from the battery 20 when it is in the unlocked position.

[0048] Therefore, when the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the locking structure 30 can be moved to the locking position to lock the battery 20, so that the battery 20 is stably kept in the mounting cavity 100 of the battery compartment 10, and the battery 20 is prevented from falling out of the mounting cavity 100 of the battery compartment 10.

[0049] When it is necessary to remove the battery 20 from the mounting cavity 100 of the battery compartment 10, the locking structure 30 can be moved from the locked position to the unlocked position to unlock the battery 20, allowing it to be removed from the mounting cavity 100 of the battery compartment 10. Conversely, when it is necessary to install the battery 20 into the mounting cavity 100 of the battery compartment 10, the locking structure 30 can be moved from the locked position to the unlocked position to allow the locking structure 30 to avoid interfering with the battery 20.

[0050] The locking structure 30 can be rotatably connected to the battery compartment 10, allowing it to rotate relative to the battery compartment 10 between a locked position and an unlocked position. Alternatively, the locking structure 30 can be slidably connected to the battery compartment 10, allowing it to slide relative to the battery compartment 10 between a locked position and an unlocked position. Of course, the locking structure 30 and the battery compartment 10 can also be connected in other ways besides rotatable or slidable connections, as long as the locking structure 30 can slide relative to the battery compartment 10 between the locked and unlocked positions.

[0051] In some embodiments, as Figure 3 and Figure 7 As shown, the locking structure 30 may include a locking part 32, and the battery 20 may include an abutment part 221. When the locking structure 30 is in the locked position, the locking part 32 is located on the side of the abutment part 221 away from the mounting cavity 100. The locking part 32 is used to abut against the abutment part 221, so that the locking structure 30 contacts the battery 20, thereby preventing the battery 20 from falling out of the battery compartment 10 and locking the battery 20.

[0052] Therefore, when the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the locking part 32 of the locking structure 30, which is in the locked position, is located on the side of the abutment part 221 away from the mounting cavity 100, so that the locking part 32 can abut against the abutment part 221 of the battery 20, thereby restricting the battery 20 from exiting the mounting cavity 100 of the battery compartment 10 and locking the battery 20.

[0053] When the locking structure 30 is in the unlocked position, the locking part 32 separates from the battery 20, causing the locking part 32 to avoid the abutment part 221, thereby unlocking the battery 20. By causing the locking part 32 of the locking structure 30 in the unlocked position to avoid the abutment part 221 of the battery 20, when the battery 20 moves in the direction of exiting the mounting cavity 100 of the battery compartment 10, the abutment part 221 of the battery 20 is not restricted by the locking part 32, thereby unlocking the battery 20.

[0054] Continue to refer to Figure 2 and Figure 3 , Figure 6 and Figure 7 The battery assembly 1 may also include a movable structure 50 for moving the locking structure 30 from a locked position to an unlocked position. When it is necessary to remove the battery 20 from the mounting cavity 100 of the battery compartment 10, or when it is necessary to install the battery 20 into the mounting cavity 100 of the battery compartment 10, the movable structure 50 can move the locking structure 30 from the locked position to the unlocked position.

[0055] The locking structure 30 may include a first magnetic element 31, and the movable structure 50 may include a movable element 51 and a second magnetic element 52 mounted on the battery 20. When the battery 20 is mounted in the mounting cavity 100, the movable element 51 is used to drive the second magnetic element 52 to move relative to the first magnetic element 31, thereby adjusting the magnetic force between the first magnetic element 31 and the second magnetic element 52, so that the first magnetic element 31 drives the locking structure 30 to move from the locked position to the unlocked position.

[0056] The battery assembly 1 provided in this application embodiment detachably installs the battery 20 into the mounting cavity 100 of the battery compartment 10. By movably connecting the locking structure 30 to the battery compartment 10, the movable member 51 and the second magnetic member 52 of the movable structure 50 are installed on the battery 20. When the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the movable member 51 drives the second magnetic member 52 to move relative to the first magnetic member 31 to adjust the magnetic force between the first magnetic member 31 and the second magnetic member 52. This allows the first magnetic member 31 to drive the locking structure 30 from the locked position that restricts the battery 20 from being removed from the battery compartment 10 to the unlocked position that separates it from the battery 20, so that the battery 20 can be removed from the battery compartment 10.

[0057] The movable structure 50 and the locking structure 30 are relatively simple. By adjusting the magnetic force between the first magnetic element 31 and the second magnetic element 52 through the movable element 51, the first magnetic element 31 drives the locking structure 30 to unlock the battery 20, so that the battery 20 can be easily taken out from the battery compartment 10.

[0058] It should be noted that the magnetic force between the first magnetic element 31 and the second magnetic element 52 includes both magnetic attraction and repulsion. The movable element 51 drives the second magnetic element 52 to move relative to the first magnetic element 31. Adjusting the magnetic force between the first magnetic element 31 and the second magnetic element 52 includes increasing or decreasing the magnetic attraction or repulsion between the first magnetic element 31 and the second magnetic element 52, switching from magnetic attraction to repulsion, or switching from repulsion to magnetic attraction. It is sufficient that by adjusting the magnetic force between the first magnetic element 31 and the second magnetic element 52, the first magnetic element 31 can move relative to the battery compartment 10, causing the first magnetic element 31 to move the locking structure 30 from the locked position of the locked battery 20 to the unlocked position of the unlocked battery 20.

[0059] Alternatively, both the first magnetic element 31 and the second magnetic element 52 can be magnets, or one of the first magnetic element 31 and the second magnetic element 52 can be a magnet, and the other can be a magnetic element that can be attracted by a magnet, as long as a magnetic force can be generated between the first magnetic element 31 and the second magnetic element 52.

[0060] In some embodiments, as Figure 4 As shown, the battery compartment 10 may be provided with an elastic member 40 connected to the locking structure 30. This elastic member 40 is used to drive the locking structure 30 from the locked position to the unlocked position. When the battery 20 is installed in the mounting cavity 100, the movable member 51 is used to drive the second magnetic member 52 away from the first magnetic member 31, so as to reduce the magnetic attraction between the first magnetic member 31 and the second magnetic member 52, so that the elastic member 40 drives the first magnetic member 31 to move the locking structure 30 from the locked position to the unlocked position.

[0061] Therefore, when the movable member 51 drives the second magnetic member 52 away from the first magnetic member 31, thereby reducing the magnetic attraction between the first magnetic member 31 and the second magnetic member 52, and making the magnetic attraction between the first magnetic member 31 and the second magnetic member 52 less than the elastic force applied by the elastic member 40 to the locking structure 30, the elastic member 40 can drive the locking structure 30 from the locked position to the unlocked position. The structure of the movable structure 50 and the locking structure 30 is very simple, and the unlocking operation of the locking structure 30 is very convenient.

[0062] In some embodiments, the movable member 51 can also be used to drive the second magnetic member 52 closer to the first magnetic member 31, so that the first magnetic member 31 drives the locking structure 30 from the unlocked position to the locked position, making it more convenient for the movable structure 50 to drive the locking structure 30 to lock the battery 20. Specifically, the second magnetic member 52 can be brought closer to the first magnetic member 31 to increase the magnetic attraction between the first magnetic member 31 and the second magnetic member 52, so that the first magnetic member 31, driven by the magnetic attraction, drives the locking structure 30 from the unlocked position to the locked position.

[0063] In other embodiments, the elastic member 40 can also be used to drive the locking structure 30 from the unlocked position to the locked position. Meanwhile, when the battery 20 is installed in the mounting cavity 100, the movable member 51 is used to drive the second magnetic member 52 closer to the first magnetic member 31 to increase the repulsive force between the first magnetic member 31 and the second magnetic member 52. This repulsive force drives the first magnetic member 31 to move the locking structure 30 from the locked position to the unlocked position.

[0064] When the movable member 51 drives the second magnetic member 52 away from the first magnetic member 31 to reduce the repulsive force between the first magnetic member 31 and the second magnetic member 52, the locking structure 30 can move from the unlocked position to the locked position under the drive of the elastic member 40.

[0065] Alternatively, the battery assembly 1 may not include the elastic element 40. When the battery 20 is installed in the mounting cavity 100, the movable element 51 drives the second magnetic element 52 to move relative to the first magnetic element 31, so that the second magnetic element 52 and the first magnetic element 31 generate a certain magnetic attraction force. This magnetic attraction force drives the first magnetic element 31 to move the locking structure 30 from the locked position to the unlocked position. The movable element 51 also drives the second magnetic element 52 to move relative to the first magnetic element 31, so that the magnetic attraction force between the second magnetic element 52 and the first magnetic element 31 is switched to a repulsive force. This repulsive force drives the first magnetic element 31 to move the locking structure 30 from the locked position to the unlocked position.

[0066] In some embodiments, the locking structure 30 may include a locking member 33 movably connected to the battery compartment 10, a locking part 32 disposed on the locking member 33, and a first magnetic member 31 mounted on the locking member 33, so that the movable member 51 drives the second magnetic member 52 to move relative to the first magnetic member 31. When the magnetic force between the first magnetic member 31 and the second magnetic member 52 is adjusted, the first magnetic member 31 can drive the locking member 33 to move relative to the battery compartment 10, thereby moving the locking structure 30 from the locked position to the unlocked position.

[0067] Among them, such as Figure 5As shown, the locking member 33 can include a first mounting groove 331, and the first magnetic member 31 can be installed in the first mounting groove 331 to make the connection between the first magnetic member 31 and the locking member 33 more stable and convenient. The locking member 33 and the first magnetic member 31 can be connected by means of screw fixing, snap fixing, adhesive fixing, etc., to prevent the first magnetic member 31 from falling out of the first mounting groove 331.

[0068] Specifically, the locking member 33 is rotatably connected to the battery compartment 10. The extension direction of the locking member 33 relative to the rotation axis of the battery compartment 10 is substantially perpendicular to the direction in which the battery 20 is inserted into the mounting cavity 100 of the battery compartment 10. The locking member 33 extends along its rotation axis in an elongated structure. The locking part 32 extends along the rotation axis of the locking member 33.

[0069] When the locking structure 30 is in the locked position, the opening of the first mounting groove 331 on the locking member 33 is located on one side of the locking member 33 along the direction in which the battery 20 exits the mounting cavity 100. There are multiple first mounting grooves 331 on the locking member 33. Each first mounting groove 331 is provided with a first magnetic element 31. The multiple first mounting grooves 331 are arranged along the rotation axis of the locking member 33.

[0070] When the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the abutment portion 221 of the battery 20 is located on the side of the battery 20 near the locking member 33. The abutment portion 221 of the battery 20 extends along the rotation axis of the locking member 33. A groove 223 is also provided on the side of the battery 20 near the locking member 33, and when the locking structure 30 is in the locked position, at least a portion of the locking portion 32 is accommodated in the groove 223. The groove 223 is located on the side of the abutment portion 221 in the direction in which the battery 20 exits the mounting cavity 100 of the battery compartment 10.

[0071] In this embodiment, the locking structure 30 can also be a second magnetic element 52, that is, the second magnetic element 52 is movably connected to the battery compartment 10 so that the second magnetic element 52 can move between the locked position and the unlocked position. When the second magnetic element 52 is in the locked position, the battery 20 is locked, and when the second magnetic element 52 is in the unlocked position, the battery 20 is unlocked.

[0072] In some embodiments, as Figures 6 to 8 As shown, the second magnetic element 52 can be slidably connected to the battery 20. The movable element 51 is used to drive the second magnetic element 52 to slide relative to the battery 20, so that the second magnetic element 52 moves closer to or away from the first magnetic element 31, thereby adjusting the magnetic force between the first magnetic element 31 and the second magnetic element 52. By making the second magnetic element 52 slidably connected to the battery 20, the second magnetic element 52 can stably move closer to or away from the first magnetic element 31 under the drive of the movable element 51, and the space occupied by the second magnetic element 52 relative to the battery 20 is small during the sliding process.

[0073] Specifically, the sliding direction of the second magnetic element 52 relative to the battery 20 can be angled with the direction in which the battery 20 is inserted into the mounting cavity 100. When the battery 20 is installed in the mounting cavity 100, the locking structure 30 is located on the side of the battery 20 along the sliding direction of the second magnetic element 52. Therefore, the travel distance of the second magnetic element 52 relative to the battery 20 can be shorter, and the second magnetic element 52 can quickly move closer to or away from the first magnetic element 31 under the drive of the movable element 51.

[0074] In some embodiments, as Figure 7 and Figure 8 As shown, the movable structure 50 includes a connector 53 connected to the movable member 51. The connector 53 is slidably installed in the slide groove 222. The second magnetic member 52 is connected to the connector 53, so that the movable member 51 is connected to the second magnetic member 52 through the connector 53, and the second magnetic member 52 is stably slidably installed in the slide groove 222 through the connector 53.

[0075] In some embodiments, a second mounting groove 531 may be provided in the connector 53, and the second magnetic element 52 may be installed in the second mounting groove 531 to connect the second magnetic element 52 to the connector 53. The connector 53 and the second magnetic element 52 may also be connected by means of screw fixing, snap fixing, adhesive fixing, etc., to prevent the second magnetic element 52 from falling out of the second mounting groove 531.

[0076] Specifically, there are multiple second mounting slots 531. Each second mounting slot 531 is provided with a second magnetic element 52, so that multiple second magnetic elements 52 are correspondingly arranged with multiple first magnetic elements 31. When the battery 20 is installed in the battery compartment 10 of the battery 20, the opening of the second mounting slot 531 is located on the side of the connector 53 facing the corresponding locking structure 30. A part of the second magnetic element 52 can extend out of the opening of the second mounting slot 531, so that the second magnetic element 52 can be closer to the first magnetic element 31, thereby increasing the maximum magnetic attraction or maximum repulsion between the second magnetic element 52 and the first magnetic element 31.

[0077] In some embodiments, locking structures 30 may be provided on both sides of the battery compartment 10 along the sliding direction of the second magnetic element 52. The movable structure 50 includes second magnetic elements 52 corresponding to the locking structures 30 on both sides of the battery compartment 10. Thus, when the battery 20 is installed in the mounting cavity 100 of the battery compartment 10, the battery 20 can be locked by the locking structures 30 on both sides of the battery compartment 10, so that the battery 20 is more stably kept in the mounting cavity 100.

[0078] The movable component 51 is used to drive the second magnetic component 52 corresponding to the two locking structures 30 to move, so as to adjust the magnetic force between the second magnetic component 52 and the corresponding first magnetic component 31, so that the first magnetic component 31 drives the corresponding locking structure 30 to move from the locked position to the unlocked position.

[0079] The movable member 51 can be a strip-shaped structure extending along the sliding direction of the second magnetic member 52. Both ends of the movable member 51 are connected to different second magnetic members 52, making the connection between the movable member 51 and the different second magnetic members 52 more convenient. Furthermore, the user can easily apply force to the strip-shaped movable member 51 to drive the second magnetic member 52 to move relative to the first magnetic member 31, thereby locking and unlocking the battery 20.

[0080] In some embodiments, as Figure 8 As shown, the battery 20 includes a limiting part 224, which is used to contact the connector 53 to limit the distance that the connector 53 can drive the second magnetic member 52 to move away from the first magnetic member 31, so that the second magnetic member 52 can directly or indirectly apply force to the battery 20 and pull the battery 20 out of the mounting cavity 100 of the battery compartment 10.

[0081] The limiting part 224 can be located on the side of the connector 53 away from the corresponding first magnetic element 31, so that the limiting part 224 can stably contact the connector 53 to limit the connector 53 and the second magnetic element 52.

[0082] Specifically, the limiting part 224 is located within the slide groove 222. The second magnetic member 52 extends from the side of the connector 53 near the first magnetic member 31, and the limiting part 224 is located on the other side of the connector 53. The limiting part 224 is used to abut against the connector 53 to limit the connection 53 and the second magnetic member 52. There are multiple limiting parts 224, and the distribution direction of the multiple limiting parts 224, the sliding direction of the second magnetic member 52, and the direction in which the battery 20 exits the mounting cavity 100 of the battery compartment 10 are perpendicular to each other. The multiple limiting parts 224 abut against the connector 53 to further improve the limiting effect on the connector 53 and the second magnetic member 52.

[0083] In some embodiments, the movable structure 50 may be located on one side of the battery 20 along the direction of exiting the mounting cavity 100 of the battery compartment 10, so that the user can more conveniently operate the movable structure 50 to lock and unlock the battery 20.

[0084] Among them, such as Figure 7 and Figure 8As shown, the battery 20 includes a cover plate 21 and a housing 22 connected sequentially along the direction of the battery 20 insertion mounting cavity 100. A groove 222 is formed between the housing 22 and the cover plate 21. The second magnetic element 52 is slidably mounted in the groove 222 so that the second magnetic element 52 is slidably connected to the battery 20.

[0085] A through hole 211 is provided in the cover plate 21. The through hole 211 extends through the cover plate 21 in the direction in which the battery 20 is removed from the mounting cavity 100. A part of the movable member 51 can be exposed through the through hole 211 so that the user can apply force to the part of the movable member 51 that extends out of the cover plate 21 away from the outer shell 22, so that the movable member 51 drives the second magnetic member 52 to slide.

[0086] In this arrangement, a portion of the movable part 51 can pass through the through hole 211 and extend out of the cover plate 21 on the side opposite to the outer casing 22, so as to facilitate gripping the movable part 51. Alternatively, the movable part 51 can be made not to extend out of the cover plate 21 on the side opposite to the outer casing 22, so that a hand can be inserted into the through hole 211 to grip the movable part 51.

[0087] Specifically, the middle part of the movable part 51 is raised and extends out of the cover plate 21 away from the outer shell 22 after passing through the through hole 211. The two ends of the movable part 51 are respectively connected to the connectors 53. The connectors 53 have a second mounting groove 531 on the side away from the movable part 51, and the second magnetic part 52 is installed in the second mounting groove 531.
