Description

Technical Field

[0001] This invention relates to the field of wearable device technology, and in particular to a strap assembly and a wearable device. Background Technology

[0002] Currently, wearable devices such as smartwatches and smart bracelets are widely used, and watch straps come in various forms. The most common configuration is a combination of long and short straps. The long strap has a hole, and the short strap has a buckle as a connection structure. The long strap is inserted into the buckle, and the buckle's pin connects to the hole, thus linking the long and short straps. However, with this connection structure alone, the free end of the long strap may stick up or wobble relative to the short strap, affecting the buckle's connection capability, resulting in low reliability. Therefore, a separate strap loop is needed to simultaneously enclose both the long and short straps to position the free end of the long strap relative to the short strap.

[0003] Therefore, how to improve the connection structure to more reliably connect the two free ends of the belt structure is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a strap assembly and a wearable device including the strap assembly, wherein the connection structure can more reliably connect the two free ends of the strap structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A belt assembly includes a connecting structure and a belt structure, wherein the two free ends of the belt structure are a first end and a second end, respectively.

[0007] The connection structure includes a housing, a first connector disposed in the housing, and a second connector disposed in the housing. The housing has a first connection hole and a second connection hole respectively provided on two opposite side walls in a first direction. The first connector passes through the first connection hole to connect to the first end, and the second connector passes through the second connection hole to connect to the second end. The first connector is snapped into the housing, and the snapping position of the first connector on the housing is adjustable to adjust the length of the belt structure extending out of the housing.

[0008] Preferably, the housing is provided with a housing through hole extending along the first direction, and a part of the structure of the first connector extends out of the housing through hole and forms an external part.

[0009] Preferably, the first connector includes a locking block, and at least two locking slots are sequentially provided on the housing along the first direction. The locking block engages with one of the locking slots to lock and fix the first connector to the housing. The locking block can move along the second direction to engage or disengage from the locking slot.

[0010] Preferably, the slot is located on the outer surface of the housing, and the card block is placed outside the housing.

[0011] Preferably, the first connector further includes a movable sleeve and a movable rod. The movable sleeve is disposed inside the housing, the first end is connected to the movable sleeve, the movable rod is inserted into the movable sleeve, and the movable rod passes through the through hole of the housing to fix the locking block. The movable rod can slide relative to the movable sleeve and the through hole of the housing along the second direction. An elastic element is provided between the movable sleeve and the movable rod so that the locking block can be engaged and pressed into the corresponding locking groove along the second direction.

[0012] Preferably, the belt structure is an integral belt.

[0013] Preferably, the housing includes a first housing and a second housing, the first housing is a groove-shaped structure with a first opening, the second housing is fixedly covered on the first opening, and the first connector and the second connector are disposed in the first housing.

[0014] Preferably, a first groove and a second groove are respectively provided on two opposite sidewalls in the first direction on the first housing, and the second housing covers the first groove to form the first connecting hole, and covers the second groove to form the second connecting hole.

[0015] Preferably, a baffle is further provided inside the first housing, and the baffle cooperates with the side wall of the housing to form a receiving groove to receive and fix the second connecting member in the first direction.

[0016] A wearable device includes a device body and a strap assembly as described above, wherein the device body is fixedly connected to the strap structure or the housing.

[0017] The belt assembly provided by the present invention includes a connecting structure and a belt structure. The two free ends of the belt structure are a first end and a second end, respectively. The connecting structure includes a housing, a first connector disposed in the housing, and a second connector disposed in the housing.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] The core of this invention is to provide a strap assembly and a wearable device including the strap assembly, wherein the connection structure can more reliably connect the two free ends of the strap structure.

[0038] For a specific embodiment of the smart device body component provided by this invention, please refer to [the following text is a separate, unrelated sentence:] Figures 1 to 8 It includes a connecting structure and a belt structure 4, with the two free ends of the belt structure 4 being the first end 41 and the second end 42, respectively.

[0039] The connecting structure includes a housing 1, a first connector 5 disposed within the housing 1, and a second connector 6 disposed within the housing 1. The housing 1 has a first connecting hole (not shown) and a second connecting hole (not shown) on two opposite sidewalls in the first direction X. The first connector 5 passes through the first connecting hole to connect to the first end 41, and the second connector 6 passes through the second connecting hole to connect to the second end 42. The remaining portion of the belt structure 4 is external to the housing 1. Specifically, the first end 41 can be connected to the second end 42 via a virtual line segment in the first direction X. The first connector 5 and the second connector 6 can abut against the housing 1 to prevent them from detaching from the housing 1.

[0040] The first connector 5 is snapped onto the housing 1 to fix its position on the housing 1. The snapping position of the first connector 5 on the housing 1 is adjustable to adjust the length of the belt structure 4 extending out of the housing 1. For a belt structure 4 of a fixed length, the length of the portion extending out of the housing 1 will also change accordingly after the length is adjusted.

[0041] For this strap assembly, both free ends of its strap structure 4 extend into the housing 1. By adjusting the snap-fit ​​position of the first connector 5 on the housing 1, the wearing length of the strap structure 4 extending out of the housing 1 can be adjusted. While ensuring that the wearing length is adjustable, there is no need to set up a separate watchband ring to position the free ends of the strap structure 4 as in the prior art. The connection of the free ends of the strap structure 4 can be achieved by using a separate connection structure, and the connection reliability is high.

[0042] Furthermore, such as Figure 2 and Figure 8 As shown, a housing through hole 21 extending along the first direction X is provided on the housing 1. A portion of the structure of the first connector 5 extends out of the housing through hole 21 and forms an external part (not shown in the figure). The external part can slide under the guidance of the housing through hole 21. By using the external part of the housing 1 as a force application point to adjust the position of the first end 41 in the first direction X, the length of the belt structure 4 extending out / into the housing 1 can be easily adjusted. Of course, in other embodiments, the first connector 5 can also be completely built into the housing 1. By providing a cover plate on the housing 1, the position of the first connector 5 can be adjusted inside the housing 1 by opening the cover plate.

[0043] Furthermore, such as Figure 2 As shown, the first connecting member 5 includes a locking block 53. At least two locking slots 22 are sequentially arranged on the housing 1 along the first direction X. The locking block 53 engages with one of the locking slots 22 to secure the first connecting member 5 to the housing 1, preventing the first connecting member 5 from moving relative to the housing 1 in the first direction X. The locking block 53 can move along the second direction Y to engage or disengage from the locking slot 22. The locking slots 22 are directly machined onto the housing 1, making machining convenient.

[0044] Wherein, the first direction X is two directions that are not parallel or collinear with the second direction Y. In this embodiment, the first direction X and the second direction Y are two perpendicular straight lines. In other embodiments, they may also be at other angles. In addition, the first direction X or the second direction Y may also be an arc direction.

[0045] In this embodiment, the slot 22 is recessed relative to the surface of the housing 1 along the second direction Y to form a groove-like structure. In this embodiment, the slot 22 is a racetrack-shaped slot, and correspondingly, the locking block 53 is a racetrack-shaped block that fits snugly against the slot 22. In other embodiments, the slot 22 can also be a rectangular slot. To ensure the adjustment accuracy of the wearing length of the strap structure 4, a larger number of slots 22 can be provided, such as... Figure 2 The array of slots 22 shown has a small distance between adjacent slots 22 or they are set close together, so that when adjusting the length of the belt structure 4 extending out of the housing 1, it is close to stepless adjustment, further ensuring the adjustment capability.

[0046] Of course, in other embodiments, a hole structure can be provided on the first connector 5, and multiple protrusion structures can be provided on the housing 1, so that the hole structure can be engaged with any of the protrusion structures.

[0047] Furthermore, such as Figure 2 As shown, the slot 22 is located on the outer surface of the housing 1, and the locking block 53 is externally mounted on the housing 1 as an external part, making it easy to observe the locking status. Of course, in other embodiments, the slot 22 can also be built into the housing 1. In this case, it is necessary to rely on touch to determine the locking and disengagement status of the locking block 53 and the slot 22.

[0048] Furthermore, such as Figure 5 , Figure 6 and Figure 8 As shown, the first connecting member 5 also includes a movable sleeve 51 and a movable rod 52. The movable sleeve 51 is disposed inside the housing 1, with its first end 41 connected to it. The movable rod 52 is inserted into the movable sleeve 51 and passes through the housing through hole 21 to fix the connecting block 53. The movable rod 52 can slide relative to the movable sleeve 51 and the housing through hole 21 in the second direction Y. An elastic element 54 is provided between the movable sleeve 51 and the movable rod 52 so that the connecting block 53 can engage and press against the corresponding slot 22 in the second direction Y, ensuring the engagement effect between the connecting block 53 and the slot 22 and improving the automation of the engagement process.

[0049] Optionally, the elastic element 54 is a compression spring, which is sleeved on the movable rod 52. One end of the elastic element 54 is fixed to the movable rod 52 by a retaining spring 55, and the other end abuts against the limiting step surface inside the movable sleeve 51. Figure 4 and Figure 5 In the diagram, the second direction Y corresponds to the left and right directions shown below. Figure 4In the middle, the movable rod 52 and the locking block 53, forming an integral part, overcome the elastic force of the elastic element 54 and move to the right. The locking block 53 disengages from the locking slot 22. At this time, the locking block 53 can be pushed along the first direction X to adjust the length of the belt structure 4 extending into the housing 1. After selecting the locking slot 22 to which the locking block 53 is to be engaged, the locking block 53 is released. Under the action of the elastic restoring force of the elastic element 54, the movable rod 52 and the locking block 53 move to the left as a whole, and the locking block 53 enters the selected locking slot 22, that is, as shown in the figure. Figure 5 As shown, the wearing length of the complete strap structure can be adjusted.

[0050] Of course, in other embodiments, the elastic element 54 can be omitted, and the reliable snap-fit ​​can be ensured by the pressing and engaging of the snap-fit ​​block 53 and the snap-fit ​​groove 22.

[0051] Furthermore, such as Figure 1 As shown, the strap structure 4 is a one-piece strap. Specifically, the strap structure 4 is made of silicone or fluororubber. In this case, when applied to a wrist-worn device, it can provide two mounting positions for the device body, such as... Figure 4 As shown, in this embodiment, the main body of the device can be mounted on the housing 1. In other embodiments, the main body of the device can also be mounted on the middle of the belt structure 4. Of course, in other embodiments, the belt structure 4 can also include two separate belts. In this case, each of the two belts has one end connected to the main body of the device, and each of the two belts has a free end, which serves as the first end 41 and the second end 42, respectively.

[0052] Furthermore, such as Figure 4 As shown, the housing 1 includes a first housing 2 and a second housing 3. The first housing 2 is a groove-shaped structure with a first opening 27. The second housing 3 is fixed to the first opening 27, specifically by applying adhesive, or in other embodiments, by being detachably connected. A first connector 5 and a second connector 6 are disposed in the first housing 2 to facilitate the assembly of the first connector 5 and the second connector 6.

[0053] The second housing 3 may have a mounting cavity, allowing it to be used as a component of the device body. Optionally, the second housing 3 includes a housing body 31 and a screen 32 disposed on the housing body 31, with the housing body 31 and the screen 32 forming a mounting cavity for the device body. Alternatively, the second housing 3 may be a single-layer cover structure.

[0054] Preferably, in the third direction Z, the first housing 2 and the second housing 3 respectively fit snugly against the first connector 5 and the second connector 6 from both sides to prevent the first connector 5 and the second connector 6 from moving along the third direction Z, thereby improving the stability of the movement of the first connector 5. Specifically, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, and the third direction Z can correspond to the direction in which the strap structure 4 and the wearing part of the human body (e.g., the wrist) are arranged sequentially when worn. In other embodiments, the third direction Z can also have other angular relationships with the first direction X and the second direction Y.

[0055] Furthermore, such as Figure 2 and Figure 7 As shown, a first groove 25 and a second groove 26 are respectively provided on two opposite sidewalls in the first direction X. The second shell 3 covers the first groove 25 to form a first connecting hole and covers the second groove 26 to form a second connecting hole. During assembly, the second shell 3 is removed, and the first connector 5 and the second connector 6 are directly inserted into the first shell 2 along the third direction Z, and then the second shell 3 is closed, which facilitates assembly. Of course, in other embodiments, the first connecting hole and the second connecting hole can also be hole structures directly formed in the middle of the two side walls of the shell 1.

[0056] Furthermore, such as Figure 2 As shown, a baffle 23 is also provided inside the first housing 2. The baffle 23 cooperates with the side wall of the housing 1 to form a receiving groove 24 to accommodate and fix the second connecting member 6 in the first direction X. This can effectively prevent the second connecting member 6 from moving arbitrarily within the housing 1 along the first direction X, so that the length of the strap structure 4 extending out of the housing 1 has only one movable end, the first end 41, during the adjustment process, making the adjustment result more certain. Of course, in other embodiments, the second connecting member 6 can also be configured to move freely in the first direction X within the housing 1. By supporting the human body parts such as the wrist when wearing it, the second connecting member 6 abuts against the housing 1 to position the second connecting member 6.

[0057] Furthermore, the first connector 5 is embedded in the first mounting groove of the first end 41, and the second connector 6 is embedded in the second mounting groove of the second end 42. The first connector 5 and the second connector 6 are respectively formed together with the belt structure 4 in the form of inserts, and the connection is reliable.

[0058] In this embodiment, when the strap assembly is applied to a wearable device (specifically, a smart wearable device, such as a smartwatch or smart bracelet), the strap structure 4 is an integral strap, and the connecting structure is integrally set on the main body of the device.

[0059] The assembly process includes: the first connector 5 (specifically the movable sleeve 51) and the second connector 6 are respectively formed together with the belt structure 4 in the form of inserts. The second connector 6 is installed in the receiving groove 24. After the second housing 3 and the first housing 2 are fixed with adhesive, the position of the second connector 6 is fixed in the housing 1. After the first connector 5 is installed in the first housing 2, it is positioned by the first housing 2 and the second housing 3 in the third direction Z. However, the first connector 5 can move along the first direction X under the guidance of the housing through hole 21, thereby driving the first end 41 of the belt structure 4 to move in the housing 1 along the first direction X, so as to adjust the length of the belt structure 4 placed outside the housing 1 for wearing.

[0060] The working principle includes: Reference Figures 7 to 9 The diagram shows the gradually decreasing length of the belt structure 4 extending from the housing 1. The movable rod 52 is connected to the movable sleeve 51 via an elastic element 54. The elastic element 54 is compressed, and the locking block 53 is locked in a slot 22 under the elastic force of the elastic element 54. When adjusting the wearing length of the belt structure 4, i.e., adjusting the length of the belt structure 4 extending from the housing 1, first, move the locking block 53 along the second direction Y. The elastic element 54 continues to be compressed, causing the locking block 53 to move out of the slot 22. Then, move the locking block 53 along the first direction X. The locking block 53 drives the first end 41 to move along the first direction X. After the length of the belt structure 4 extending from the housing 1 is adjusted to a suitable position, place the locking block 53 into the selected slot 22. The movable rod 52 is then fixed again under the action of the elastic element 54. This process allows for repeated adjustment of the length of the belt structure 4 extending from the housing 1.

[0061] In addition to the aforementioned strap assembly, the present invention also provides a wearable device, such as a smart wristband, more specifically a bracelet or watch. This wearable device includes a strap assembly, which can specifically be the strap assembly provided in any of the above embodiments; the beneficial effects can be referred to the respective embodiments above. The wearable device also includes a device body, which is fixedly connected to the strap structure 4 or the housing 1. The structures of other parts of the wearable device are described in the prior art and will not be repeated here.
