In this way, it is possible to facilitate the rapid installation and disassembly between the belt body and the device body, thereby meeting the replacement and maintenance needs of the wearable device and the personalized needs of the user, thereby enhancing the market competitiveness of the product.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] The present invention proposes a wearable device. It can be understood that the wearable device includes: a watch, a smart watch or a smart bracelet that can be worn on the wrist, a motion monitoring module that can be worn on the ankle, and a 3D display device that can be worn on the head.

[0046] In one embodiment of the present invention, referring to Figure 1 , 2 , 5 and 6, among which, Figure 6 The first magnet is in a first state, the wearable device comprising:

[0047] Equipment body 10, belt body 20;

[0048] A magnet assembly 30, comprising a first magnet 31 and a second magnet 32, wherein one of the device body 10 and the belt body 20 is rotatably connected to the first magnet 31, and the other is fixedly connected to the second magnet 32; and

[0049] The clamping structure includes a first clamping portion 41 provided on the first magnet 31, and a second clamping portion 42 fixed relative to the second magnet 32. The first magnet 31 rotates under the magnetic force of the second magnet 32. The first magnet 31 can rotate and has a first state and a second state. In the first state, the first clamping portion 41 is clamped in the second clamping portion 42. In the second state, the first clamping portion 41 is separated from the second clamping portion 42.

[0050] The magnetic force generated by the second magnet 32 ​​on the first magnet 31 can drive the first magnet 31 to rotate from the second state to the first state.

[0051] Specifically, before the belt body 20 is assembled, the first magnet 31 stays in the second state; and in the process of assembling the belt body 20 to the device body 10, the distance between the first magnet 31 and the second magnet 32 ​​becomes smaller and smaller, resulting in the first magnet 31 being subjected to an increasingly greater magnetic force of the second magnet 32. After reaching a certain force threshold, the magnetic force drives the first magnet 31 to rotate to the first state, causing the first clamping portion 41 to rotate and be clamped in the second clamping portion 42, thereby achieving the installation of the belt body 20 and the device body 10. When the belt body 20 needs to be removed from the device body 10, it is only necessary to release or block the magnetic force of the second magnet 32 ​​on the first magnet 31, so that the first magnet 31 can be rotated back to the second state, causing the first clamping portion 41 to be separated from the second clamping portion 42, thereby releasing the installation of the belt body 20 and the device body 10. In this way, the belt body 20 and the device body 10 can be quickly installed and removed, thereby meeting the replacement and maintenance needs of the wearable device and the personalized needs of the user, thereby improving the market competitiveness of the product.

[0052] It should be noted that the magnet can refer to a part made of magnetic material, such as a natural magnet or artificial magnet steel such as neodymium iron boron, or an electromagnet, as long as it is a structure that can generate a magnetic field, and the present invention does not make specific limitations on this. The first magnet 31 can be set on the device body 10 or on the belt body 20, and the present invention does not make specific limitations on this. For the convenience of explanation, the following will take the example of the first magnet 31 being set on the device body 10 and the second magnet 32 ​​being set on the belt body 20 for explanation.

[0053] Please refer to Figures 6 to 8 ,in, Figure 7 and 8 The belt body in the embodiment is not equipped with the second magnet. In this embodiment, optionally, a magnetic blocking gap 20b is formed between the first magnet 31 and the second magnet 32, and the belt body 20 is provided with a avoidance hole 20c corresponding to the magnetic blocking gap 20b, and the avoidance hole 20c is connected to the magnetic blocking gap 20b. In this way, the auxiliary plug-in with high magnetic permeability is passed through the avoidance hole 20c on the belt body 20 and inserted into the magnetic blocking gap 20b, so that the magnetic field of the second magnet 32 ​​is enclosed in the closed magnetic circuit between the auxiliary plug-in and the second magnet 32, and the magnetic field in the space outside the closed magnetic circuit is blocked, thereby weakening or even eliminating the magnetic force of the second magnet 32 ​​on the first magnet 31, so that the first magnet 31 can rotate and return to the second state. Specifically, the material of the auxiliary plug-in can be soft iron, silicon steel, permalloy, etc. The wearable device is equipped with the auxiliary plug-in when it leaves the factory, similar to the card pin that is equipped when the mobile phone leaves the factory, so that it is convenient for users to disassemble the belt body 20 as needed. Of course, in the embodiment where the second magnet is configured as an electromagnet, the circuit of the electromagnet can also be controlled to be disconnected to cancel the magnetic field generated by the electromagnet, thereby eliminating the magnetic force of the second magnet on the first magnet.

[0054] Please refer to Figure 1 and 2 There are many ways for the first magnet 31 to rotate and return to the second state. For example, in this embodiment, the magnet assembly 30 further includes a third magnet 33. The third magnet 33 is located on the side of the first magnet 31 away from the second magnet 32. The first magnet 31 is used to make the first magnet 31 have a tendency to rotate from the second state to the first state. Please refer to Figure 3 and 4 ,in, Figure 3 for Figure 2 Schematic diagram of the position of the first magnet when it is in the second state. At this time, the belt body has not been installed, so the first magnet is only affected by the magnetic force of the third magnet and remains in the second state; Figure 4 for Figure 2 Schematic diagram of the position of the first magnet when it is in the first state, at this time the belt body has been installed in place, the first magnet is simultaneously acted upon by the magnetic forces of the second magnet and the third magnet, and rotates from the second state to the first state, and then remains in the first state; and when the second magnet is away from the first magnet, the first magnet will rotate from the first state to the second state under the magnetic force of the third magnet, that is, it recovers and remains in the second state. Specifically, in this embodiment, the third magnet 33 is arranged on the device body 10, the second magnet 32, the first magnet 31 and the third magnet 33 are sequentially distributed along the first direction, when the first magnet 31 is in the first state, the magnetic pole directions of the second magnet 32, the first magnet 31 and the third magnet 33 are all extended along the first direction, that is, the second magnet 32 ​​generates a magnetic attraction force on the first magnet 31, and the third magnet 33 also generates a magnetic attraction force on the first magnet 31, and the directions of the two magnetic attractions are opposite. It should be noted that the magnetic pole direction refers to the direction from the magnetic pole S to the magnetic pole N. Before the belt body 20 is installed, the first magnet 31 can be kept in the first state due to the magnetic attraction force generated by the third magnet 33 on the first magnet 31; and when the belt body 20 is installed to the device body 10 along the first direction, the magnetic attraction force of the second magnet 32 ​​on the first magnet 31 gradually increases until it is greater than the magnetic attraction force of the third magnet 33 on the first magnet 31, and the first magnet 31 will rotate from the second state to the first state. When the magnetic attraction force of the second magnet 32 ​​on the first magnet 31 gradually decreases until it is less than the magnetic attraction force of the third magnet 33 on the first magnet 31, the first magnet 31 will rotate from the first state to the second state. In this way, the first magnet 31 can be freely switched between the first state and the second state with a simple structure, and the switching process is stable and reliable. Secondly, when the user disassembles the belt body 20, he only needs to insert the auxiliary plug into the magnetic blocking gap 20b, which has the advantage of convenient operation.

[0055] Of course, in other embodiments, the third magnet may generate a magnetic repulsion force on the first magnet, and the second magnet may also generate a magnetic repulsion force on the first magnet, and the directions of the two magnetic repulsion forces are opposite; or the third magnet may generate a magnetic repulsion force on the first magnet, and the second magnet may generate a magnetic attraction force on the first magnet, and the directions of the two magnetic repulsion forces are arranged in the same direction, that is, the magnetic repulsion force and the magnetic attraction force are used in combination. In other embodiments, the first magnet may be provided with a rotating shaft on two opposite sides, the rotating shaft is rotatably connected to the device body, and one end of the rotating shaft passes through the device body and is exposed to the outside for manual rotation by the user. In some other embodiments, a rotating shaft may be provided on opposite sides of the first magnet, the first clamping portion is configured as a clamping protrusion protruding from the rotating shaft, the second clamping portion is configured as a clamping slot, and the first magnet is also provided with a counterweight block protruding therefrom, the counterweight block and the clamping protrusion are provided on opposite sides of the rotating shaft, and the counterweight block is located on the side of the rotating shaft away from the second magnet. In this way, when the first magnet is not affected by the magnetic force of the second magnet, the counterweight block with a very high material density generates a rotational torque on the rotating shaft that can drive the first magnet to rotate, thereby causing the clamping protrusion to disengage from the clamping slot, that is, causing the first magnet to rotate from the first state to the second state.

[0056] It is worth mentioning that in this embodiment, since the third magnet 33 and the second magnet 32 ​​both exert magnetic attraction on the first magnet 31, the directions of action of these two magnetic attraction forces are opposite to each other. Therefore, during the installation of the belt body 20, only when the magnetic attraction of the second magnet 32 ​​on the first magnet 31 is greater than the magnetic attraction of the third magnet 33 on the first magnet 31, the first magnet 31 will rotate from the second state to the first state. In other embodiments, for example, in an embodiment where the first magnet is provided with a rotating shaft, a locking protrusion and a counterweight, assuming that the first torque generated by the counterweight on the first magnet is in a clockwise direction, and the third magnet applies a magnetic repulsion force to the first magnet, the second torque generated by the magnetic repulsion force is in a counterclockwise direction and is smaller than the first torque, then the first magnet will remain in the second state at this time; during the installation of the belt body, the second magnet applies a magnetic attraction force (in the same direction as the magnetic repulsion force) to the first magnet, and the third torque generated by the magnetic attraction force is in a counterclockwise direction, and after the sum of the second torque and the third torque is greater than the first torque, the counterweight is not sufficient to keep the first magnet in the second state, so the first magnet will rotate from the second state to the first state; similarly, when the belt body is disassembled, when the sum of the second torque and the third torque is less than the first torque, the first magnet will rotate from the first state to the second state.

[0057] In this embodiment, optionally, the first magnet 31, the second magnet 32 ​​and the third magnet 33 are all configured as permanent magnets. Specifically, it is sufficient to ensure that after the belt body 20 is installed in place, the magnetic attraction of the second magnet 32 ​​on the first magnet 31 is greater than the magnetic attraction of the third magnet 33 on the first magnet 31. In this way, under the premise of ensuring that the first magnet 31 can freely and reliably switch between the first state and the second state, the structure of the wearable device can be simplified, thereby reducing the manufacturing cost.

[0058] Specifically, there are many ways to ensure that the magnetic attraction of the second magnet 32 ​​to the first magnet 31 is greater than the magnetic attraction of the third magnet 33 to the first magnet 31. For example, in this embodiment, optionally, the magnetic permeability of the second magnet 32 ​​is greater than the magnetic permeability of the third magnet 33; on the reference plane perpendicular to the first direction, the projection area of ​​the second magnet 32 ​​is greater than the projection area of ​​the third magnet 33, that is, the magnetic pole area of ​​the second magnet 32 ​​is greater than the magnetic pole area of ​​the third magnet 33; in the first direction, the thickness of the second magnet 32 ​​is greater than the thickness of the third magnet 33. It can be understood that under the conditions of the same magnetic material and magnetic pole area, the greater the thickness of the magnet (that is, the size along the magnetic pole direction), the greater the magnetic force; under the conditions of the same magnetic material and magnet thickness, the greater the magnetic pole area of ​​the magnet, the greater the magnetic force; under the conditions of the same magnet thickness and magnetic pole area, the greater the magnetic permeability of the magnetic material, the greater the magnetic force. Therefore, under the limitation of the space arranged in the belt body 20 and the device body 10 , at least one of the above three parameters is selectively limited to ensure that the magnetic attraction of the second magnet 32 ​​to the first magnet 31 is greater than the magnetic attraction of the third magnet 33 to the first magnet 31 .

[0059] Please refer to Figures 2 to 4 In this embodiment, optionally, the first magnet 31 is provided with a first side surface 311 and a second side surface 312 opposite to each other, the first side surface 311 faces the second magnet 32, the second side surface 312 faces the third magnet 33, the third magnet 33 is provided with a third side surface 331 corresponding to the second side surface 312, and the third side surface 331 is arranged perpendicular to the magnetic pole direction of the third magnet 33; when the first magnet 31 is in the second state, the second side surface 312 is arranged parallel to the third side surface 331. It can be understood that before the belt body 20 is installed, when the first magnet 31 is in the intermediate state from the second state to the first state, the second side surface 312 and the third side surface 331 are spatially intersected, at this time, the first magnet 31 has not reached a force balance state, and will rotate towards a state where the second side surface 312 and the third side surface 331 are parallel to each other under the magnetic attraction of the third magnet 33, and finally rotate to the second state and reach a force balance state, so that the first magnet 31 remains in the first state. In this way, by limiting the relative positional relationship between the second side surface 312 and the third side surface 331 , the first magnet 31 can automatically rotate and remain in the second state, which has the advantages of simple structure and stable and reliable operation.

[0060] In this embodiment, optionally, the second magnet 32 ​​is provided with a fourth side 321 corresponding to the first side 311, and the fourth side 321 is arranged perpendicular to the magnetic pole direction of the second magnet 32; when the first magnet 31 is in the first state, the first side 311 is arranged parallel to the fourth side 321. It can be understood that during the installation of the belt body 20, when the first magnet 31 is still in the second state, the first side 311 and the fourth side 321 are spatially intersecting; as the belt body 20 is continuously approaching the device body 10 along the first direction, the magnetic attraction of the second magnet 32 ​​on the first magnet 31 will gradually increase until the magnetic attraction exceeds the magnetic attraction of the third magnet 33, causing the first magnet 31 to re-enter a state of unbalanced force, and due to the stronger magnetic attraction of the second magnet 32, the second side 312 and the third side 331 are rotated to a state parallel to each other, and finally rotated to the first state and reached a new state of force balance, so that the first magnet 31 remains in the first state. In this way, by limiting the relative position relationship between the first side surface 311 and the second side surface 312 on the first magnet 31, that is, the angle formed between the first side surface 311 and the second side surface 312 is set to be an acute angle, the first magnet 31 can automatically rotate and switch between the first state and the second state, which has the advantages of simple structure and stable and reliable operation.

[0061] In this embodiment, optionally, the first magnet 31 and the third magnet 33 are spaced apart along the first direction, and the second magnet 32 ​​and the first magnet 31 are spaced apart along the first direction. In this way, it is possible to ensure that the first magnet 31 can rotate freely between the first state and the second state, and will not be stuck and unable to rotate freely due to touching the third magnet 33 and the second magnet 32.

[0062] Please refer to Figure 2 , 6 8, in order to simplify the clamping structure, in this embodiment, further, the first magnet 31 is provided with a rotating shaft 313 on two opposite sides in a direction perpendicular to the first direction, the rotating shaft 313 is rotatably connected to the device body 10, the first clamping portion 41 is configured as a clamping protrusion 314 convexly provided on the rotating shaft 313, and the second clamping portion 42 is configured as a clamping groove 20d. Of course, in other embodiments, the first magnet can also be provided with shaft holes on two opposite sides in a direction perpendicular to the first direction, the device body is provided with a rotating shaft corresponding to the shaft hole, the rotating shaft is rotatably connected to the shaft hole, the first magnet is provided with a cantilever convexly toward the second magnet, the end of the cantilever is provided with a clamping hole, and the second magnet is provided with a clamping protrusion corresponding to the clamping hole.

[0063] In this embodiment, optionally, the card slot 20d is provided on the belt body 20. In this way, the structure of the second magnet 32 ​​can be simplified, thereby reducing the manufacturing cost of the second magnet 32 ​​and facilitating the installation of the second magnet 32 ​​on the belt body 20. Of course, in other embodiments, the card slot can also be provided on the second magnet.

[0064] In this embodiment, optionally, the first magnet 31, the rotating shaft 313, and the snap-on protrusion 314 are integrally formed. For example, they are formed into an injection-molded magnet by an injection molding process. In this way, the assembly process of the first magnet 31, the rotating shaft 313, and the snap-on protrusion 314 when they are separately arranged can be saved, thereby reducing the manufacturing cost and material management cost. Of course, in other embodiments, the first magnet, the rotating shaft, and the snap-on protrusion can also be separately arranged and then fixed together by bonding or welding.

[0065] In this embodiment, further, the belt body 20 is provided with a mounting groove 20a, the second magnet 32 ​​is arranged in the mounting groove 20a, the notch of the mounting groove 20a is arranged toward the first magnet 31, and when the first magnet 31 is in the first state, the first magnet 31 is at least partially arranged in the mounting groove 20a. That is, the first magnet 31 will complete the rotation from the second state to the first state in the mounting groove 20a. In this way, the first magnet 31 and the second magnet 32 ​​can be hidden to make the appearance of the device more neat, and the two magnets can be protected. Specifically, the second magnet 32 ​​is bonded and fixed to the bottom of the mounting groove 20a. In this way, the assembly process of the second magnet 32 ​​can be simplified and the installation is convenient for workers. Of course, in other embodiments, the second magnet can also be partially embedded in the belt body, or arranged on the outer side of the belt body; the second magnet can also be fixed in the mounting groove by screw locking, clamping structure, riveting structure, etc.

[0066] In this embodiment, optionally, the belt body 20 includes a belt body and a slot body provided in the belt body, the mounting slot 20a is formed in the slot body, and the material of the belt body is configured as a flexible material. Specifically, the material of the belt body can be an elastic material such as silicone, elastic polyvinyl chloride, etc., or a soft material such as textiles, leather, etc., so that the belt body 20 can be more convenient to wear and fit the user's limbs better after wearing. Since the belt body is a flexible material, it may be difficult to directly form the mounting slot 20a thereon, or the formed mounting slot 20a is not sufficient to provide a good support and fixation effect for the second magnet 32, so a slot body structure made of a harder material such as plastic, metal or ceramic is used to support and fix the second magnet 32. Specifically, in this embodiment, the material of the belt body is configured as silicone, and the material of the slot body is configured as plastic material. Of course, in other embodiments, the belt body can also be directly made of a harder material, for example, configured as a plastic chain structure or a metal chain structure, and a mounting slot is formed on the belt body.

[0067] In this embodiment, the clamping groove 20d is optionally formed in the groove body. That is, the installation groove 20a and the clamping groove 20d are simultaneously formed during the injection molding of the groove body, the installation groove 20a is used to support and fix the second magnet 32, and the clamping groove 20d is used to limit and fix the clamping protrusion 314.
