Description
Technical Field
[0001] The present application relates to the technical field of wearable devices, and in particular to a connection component and a wearable device. Background Art
[0002] The wearable device includes a device body and a connecting belt, which is connected to the device body. The connecting belt and the device body are arranged to form a wearing space, so that the device body is fixedly tied to the user's wearing part, such as the wrist. Since the sizes of the wearing parts of different users are different, in order to meet the wearing needs of users, the size of the wearing space can be adjusted as needed. For example, the connecting belt is set to be foldable, one end of the connecting belt is folded on one side of the connecting belt, and the size of the wearing space is adjusted by adjusting the length of the connecting belt connected to the device body, and the folded end is limited after being adjusted in place to keep the size of the wearing space at the set value. In some related technologies, a buckle is provided on the connecting belt to fix the folded end, but the fixing operation of the buckle is not very convenient, and the product usability is poor; in other related technologies, the material cost of the component used to fix the folded end is relatively high, resulting in high product cost. Utility Model Content

The first end is used to connect to the device main body, the second end is connected to the magnetic part, and the connecting section is connected to a matching part, and the position of the matching part on the connecting section is adjustable. In the worn state, the second end is folded on one side of the connecting section, and the magnetic part can be connected to the matching part in a magnetic attraction matching manner to limit the movement of the second end relative to the connecting section. The preparation materials of the magnetic part and the matching part are hard magnetic material and soft magnetic material, respectively.
[0005] On the other hand, the present application provides a wearable device, which includes the connection component as described above and a device body, wherein the connection component is connected to the device body and is surrounded by the device body to form a wearing space.

[0016] This application provides a wearable device. Figure 1 The wearable device 1000 may include a connection component 100 and a device body 200. The connection component 100 is connected to the device body 200 and is surrounded by the connection component 100 to form a wearing space 210, so that the device body 200 is fixedly tied to the user's wearing part. The device body 200 may be a device such as a smart watch or a bracelet. The following describes the present application using a smart watch as an example. The size of the wearing space 210 can be adjusted as needed to meet the user's wearing needs. For example, the size of the wearing space 210 can be adjusted by changing the length of the connection component 100 connected to the device body 200.
[0017] The present application provides a connection assembly. Figure 2The connection component 100 may include a connection belt 10, a matching piece 21, a magnetic piece 31, a first connection piece 40, and a second connection piece 50. The connection belt 10 is in a belt shape and has a certain width, which can increase the contact area between the connection belt 10 and the user's wearing part to disperse the force at the contact point, thereby improving the comfort when wearing. The material of the connection belt 10 can be leather, rubber, silicone, or fibers such as cotton and linen. The connection belt 10 can be provided with a pattern or texture to enhance the appearance of the connection component 100.
[0018] The connecting belt 10 includes a first end 11, a second end 12, and a connecting section 13 connected between the first end 11 and the second end 12. The first end 11 is used to connect with the device body 200. The first end 11 can be directly connected with the device body 200, for example, the first end 11 is connected to one side of the device body 200 by bonding or snapping; or the first end 11 is indirectly connected with the device body 200 through other components, for example, the first connecting member 40 is connected to the first end 11, and the first end 11 is connected to one side of the device body 200 through the first connecting member 40. The first connecting member 40 can be a buckle, and the first end 11 can be connected to the first connecting member 40 by bonding or snapping. The first connecting member 40 can be provided with an opening to facilitate assembly and connection with the device body 200. The second end 12 is connected to the magnetic member 31, and the connecting section 13 is connected with the matching member 21. It can be understood that the connection between the second end 12 and the magnetic member 31 and the connection between the connecting section 13 and the matching member 21 can be a direct connection between the two components, or an indirect connection with the aid of other components. The connection between the second end 12 and the magnetic member 31 can be bonding or snapping. The connection between the connecting section 13 and the matching member 21 can be a movable connection, such as a sliding connection. The position of the matching member 21 on the connecting section 13 is adjustable. Exemplarily, a through hole is provided on the matching member 21, and the connecting section 13 is inserted into the through hole of the matching member 21. A certain force is applied to the matching member 21 or the connecting section 13, so that the matching member 21 and the connecting section 13 can move relative to each other, thereby adjusting the position of the matching member 21 on the connecting section 13; when the matching member 21 is adjusted to the preset position on the connecting section 13, the force is removed, and the matching member 21 and the connecting section 13 are relatively stationary, so that the matching member 21 remains in the preset position.
[0019] In the wearing state, the second end portion 12 is folded on one side of the connecting section 13 to adjust the length of the connecting belt 10 connected to the device body 200. The second end portion 12 is folded on one side of the connecting section 13, and a bending section 131 is formed on the connecting section 13. The bending section 131 can be directly connected to the other side of the device body 200, for example, the device body 200 is provided with a connecting rod, and the bending section 131 is sleeved on the connecting rod; or, the bending section 131 is indirectly connected to the device body 200 through other components, for example, the second connecting member 50 is sleeved on the connecting section 13, the second connecting member 50 is located at the bending section 131, and the second connecting member 50 is used to connect to the other side of the device body 200. The second connecting member 50 can be a buckle. When it is necessary to increase the length of the connecting belt 10 connected to the device body 200, the distance from the second end 12 to the bending section 131 can be reduced, so that the length of the overlapping part of the connecting section 13 is reduced; conversely, when it is necessary to reduce the length of the connecting belt 10 connected to the device body 200, the distance from the second end 12 to the bending section 131 can be increased, so that the length of the overlapping part of the connecting section 13 is increased.
[0020] The magnetic member 31 can be connected to the matching member 21 in a magnetically matched manner to limit the movement of the second end 12 relative to the connecting section 13, thereby maintaining the length of the connecting belt 10 connected to the device body 200. To set the magnetic member 31 and the matching member 21 to be magnetically matched, it is only necessary to move the position of the magnetic member 31 or the matching member 21, and the magnetic member 31 and the matching member 21 can be fitted with each other to make the two magnetically matched, thereby maintaining the length of the connecting belt 10 connected to the device body 200. The limiting operation of the second end 12 is simple, which can improve the usability of the product. It can be understood that the setting positions of the magnetic member 31 and the matching member 21 can be interchanged, that is, the second end 12 is connected to the matching member 21, and the magnetic member 31 is connected to the connecting section 13, as long as the magnetic member 31 and the matching member 21 can achieve magnetic matching.
[0021] The materials used to prepare the magnetic part 31 and the matching part 21 are hard magnetic material and soft magnetic material, respectively. Hard magnetic material has a wide hysteresis loop, high coercive force, high remanence, and can maintain constant magnetism once magnetized. Soft magnetic material refers to a ferromagnetic material with a narrow hysteresis loop, high magnetic permeability, low remanence, low coercive force and low magnetic resistance. Soft magnetic material is easy to magnetize and also easy to demagnetize. Specifically, the material used to prepare the magnetic part 31 can be neodymium iron boron, high carbon steel or titanium cobalt alloy, etc., and the material used to prepare the matching part 21 can be a metal material such as iron, cobalt or nickel. The materials used to prepare the magnetic part 31 and the matching part 21 are hard magnetic material and soft magnetic material, respectively, so that only the magnetic part 31 is a hard magnetic material, and the matching part 21 is a relatively low-cost soft magnetic material, which can reduce the cost of the product.
[0022] See also Figure 2-Figure 5In one embodiment, the connection component 100 includes an adjustment component 20 and a limit component 30, wherein the adjustment component 20 is used to adjust the length of the connection belt 10 connected to the device body 200, and the limit component 30 is used to limit the movement of the second end 12 relative to the connection section 13, thereby maintaining the length of the connection belt 10 connected to the device body 200. Among them, the adjustment component 20 includes a matching piece 21 and an adjustment shell 22, and the limit component 30 includes a magnetic piece 31 and a limit shell 32. Optionally, the material of the adjustment shell 22 and the limit shell 32 is metal, alloy or plastic. The matching piece 21 is connected to the adjustment shell 22. The connection between the matching piece 21 and the adjustment shell 22 can be bonding, welding or threaded connection. Exemplarily, in the wearing state, the matching piece 21 can be connected to the side of the adjustment shell 22 close to the second end 12, so that the second end 12 is magnetically connected to the magnetic piece 31 after being folded to the side of the connection section 13.
[0023] The adjusting housing 22 is provided with a belt-threading slot 221, and the connecting section 13 is threaded through the belt-threading slot 221. The connecting section 13 can move in the belt-threading slot 221, thereby changing the positional relationship between the connecting section 13 and the adjusting housing 22. Since the fitting 21 is connected to the adjusting housing 22, the position of the fitting 21 on the connecting section 13 can be adjusted by changing the positional relationship between the connecting section 13 and the adjusting housing 22, thereby adjusting the length of the connecting belt 10 connected to the device body 200. For example, when it is necessary to increase the length of the connection belt 10 connected to the device body 200, the connection section 13 in the belt threading groove 221 can be dragged to move in the direction of the first end 11, and the matching piece 21 moves away from the first end 11 to reduce the distance from the second end 12 to the bending section 131, so that the length of the overlapping part of the connection section 13 is reduced; conversely, when it is necessary to reduce the length of the connection belt 10 connected to the device body 200, the connection section 13 in the belt threading groove 221 can be dragged to move in the direction of the second end 12, and the matching piece 21 moves in the direction close to the first end 11 to increase the distance from the second end 12 to the bending section 131, so that the length of the overlapping part of the connection section 13 is increased. The limit housing 32 is connected to the second end 12, and the magnetic member 31 is connected to the limit housing 32. Specifically, the connection between the limit housing 32 and the second end 12 can be bonding or clamping; the connection between the magnetic member 31 and the limit housing 32 can be bonding, welding or threaded connection. The matching piece 21 and the magnetic piece 31 are connected to the connecting belt 10 through the adjusting shell 22 and the limiting shell 32 respectively, and the adjusting shell 22 and the limiting shell 32 do not need to use hard magnetic materials or soft magnetic materials. Compared with the matching piece 21 and the magnetic piece 31 being directly connected to the connecting belt 10, the amount of relatively expensive hard magnetic materials and soft magnetic materials can be reduced, thereby further reducing the cost of the product.
[0024] In one embodiment, if Figure 2-Figure 5 As shown, the limiting shell 32 is provided with a receiving cavity 321 and a matching groove 322. An opening is provided on one side of the receiving cavity 321. The magnetic member 31 is received in the receiving cavity 321, and the second end 12 is inserted into the receiving cavity 321 through the opening. The magnetic member 31 is received in the receiving cavity 321, and the cavity wall of the receiving cavity 321 can limit the displacement of the magnetic member 31, so that the magnetic member 31 is not easy to fall off from the limiting shell 32. The second end 12 is inserted into the receiving cavity 321, that is, the limiting shell 32 is sleeved outside the second end 12. The limiting shell 32 has a certain decorative effect, which can enhance the appearance expression of the connection component 100. The matching groove 322 is located on one side of the receiving cavity 321 and is connected to the receiving cavity 321. Part of the surface of the magnetic member 31 is exposed to the limiting shell 32 through the matching groove 322. The magnetic member 31 is connected to the matching member 21 in a magnetic attraction matching manner via the matching groove 322. Since the groove wall of the matching groove 322 has a certain thickness, the lateral displacement of the matching member 21 in the direction perpendicular to the magnetic attraction force can be limited, so as to further limit the movement of the second end portion 12 relative to the connecting section 13. The side of the magnetic member 31 exposed to the limiting shell 32 is the matching surface 311, and the positive projection of the outer contour of the groove wall of the matching groove 322 on the matching surface 311 is located inside the matching surface 311, so that the opening area of the matching groove 322 is smaller than the area of the magnetic member 31 on the side where the matching surface 311 is located. The groove wall of the matching groove 322 is constrained on the outer periphery of the magnetic member 31, which can further limit the magnetic member 31 from falling off from the limiting shell 32.
[0025] Optionally, the second end portion 12 abuts against the magnetic member 31 to limit the movement of the magnetic member 31 toward the opening side of the accommodating cavity 321 , so that the magnetic member 31 is not easy to fall off from the limiting shell 32 , thereby improving the reliability of the connection between the magnetic member 31 and the limiting shell 32 .
[0026] The magnetic member 31 and the matching member 21 may be in the shape of a column or a block. The area of the side of the magnetic member 31 and the matching member 21 that are in contact with each other during magnetic attraction can be roughly equal, so that the two can fit each other. Figure 2-Figure 5 As shown, the magnetic member 31 and the matching member 21 have a length direction and a width direction, the length direction is greater than the width direction, the connecting belt 10 is in a belt shape, the connecting belt 10 has a width direction, and the length direction of the magnetic member 31 and the matching member 21 is arranged along the width direction of the connecting belt 10. That is, the magnetic member 31 and the matching member 21 can be in the shape of a long strip, wherein the extension direction of the length direction is the width direction of the connecting belt 10, the space in the width direction of the connecting belt 10 can be fully utilized, the size of the magnetic member 31 and the matching member 21 along the length direction of the connecting belt 10 can be reduced, and the size of the limiting shell 32 and the adjusting shell 22 along the length direction of the connecting belt 10 can be reduced accordingly, thereby improving the wearing comfort.
[0027] See also Figure 2-Figure 5 In one embodiment, the adjustment component 20 includes a limiting flange 23, which is connected to the adjustment housing 22 and is arranged around the outer periphery of the matching piece 21. The matching piece 21 can be directly connected to the adjustment housing 22, or can be connected to the adjustment housing 22 through the limiting flange 23. The matching piece 21 can also be connected to both the limiting flange 23 and the adjustment housing 22. The limiting flange 23 is arranged around the outer periphery of the matching piece 21, and the limiting flange 23 forms a protective housing for the matching piece 21, so that the matching piece 21 is not easy to fall off. The limiting housing 32 is provided with a limiting groove 323, and the groove wall of the limiting groove 323 is arranged around the groove wall of the matching groove 322. When the magnetic piece 31 is connected to the matching piece 21, the limiting flange 23 is engaged in the limiting groove 323, which can limit the lateral displacement of the matching piece 21 in the direction perpendicular to the magnetic attraction force, so as to further limit the movement of the second end 12 relative to the connecting section 13.
[0028] In one embodiment, if Figure 2-Figure 5 As shown, the adjustment component 20 includes a limiting protrusion 24, which is connected to the side wall of the belt-threading groove 221 of the adjustment housing 22, and the connecting section 13 can abut against the limiting protrusion 24 to limit the relative movement between the connecting section 13 and the matching piece 21, thereby maintaining the length of the connecting belt 10 connected to the device body 200. The limiting protrusion 24 can be one or more, and the plurality of limiting protrusions 24 can be arranged in a row or array. Specifically, the connecting section 13 is inserted into the belt-threading groove 221, and the limiting protrusion 24 protrudes from the side wall of the belt-threading groove 221. The connecting section 13 can abut against the limiting protrusion 24, and the limiting protrusion 24 increases the resistance during the relative movement between the connecting section 13 and the adjustment housing 22, thereby limiting the relative movement between the connecting section 13 and the adjustment housing 22. Since the adjustment housing 22 is connected to the matching piece 21, the relative movement between the connecting section 13 and the matching piece 21 can be limited.
[0029] Optionally, the limiting flange 23, the limiting protrusion 24 and the adjusting housing 22 are processed separately and then assembled and connected. Alternatively, the limiting flange 23 and / or the limiting protrusion 24 are integrally formed with the adjusting housing 22 to simplify the processing technology of the adjusting assembly 20.
[0030] See also Figure 2-Figure 5In one embodiment, an adjustment hole 222 is provided on the adjustment housing 22, the adjustment hole 222 is connected to the belt-threading groove 221, the limiting protrusion 24 protrudes toward the side where the adjustment hole 222 is located, and the connecting section 13 is exposed to the adjusting housing 22 through the adjustment hole 222, and the adjustment hole 222 is used to adjust the position of the matching piece 21 on the connecting section 13. Exemplarily, when it is necessary to adjust the position of the matching piece 21 on the connecting section 13, the connecting section 13 can be pulled out through the adjustment hole 222 so that the connecting section 13 does not contact the limiting protrusion 24, and then the connecting section 13 can be dragged to move in the belt-threading groove 221, thereby changing the positional relationship between the connecting section 13 and the adjustment housing 22, and then adjusting the position of the matching piece 21 on the connecting section 13.
[0031] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
