Description

Technical Field

[0001] The present invention relates to the technical field of connection structures, and more specifically, to a wearable device and a connection device. Background Art

[0002] Wearable devices, such as watches and sports bracelets, have become essential personal products for many people. They generally consist of a device body and a strap. Taking wrist-worn devices such as bracelets or watches as an example, in order to adapt to various wearing scenarios and improve product competitiveness, the connection between the strap and the device body generally uses a spring ear connection, which is convenient for consumers to replace the strap when changing the wearing scenario or having other usage needs.

[0003] However, the production line assembly of the ear connection structure is difficult, and other tools are needed to assist in disassembly, making it inconvenient to disassemble the belt. In addition, the belt is connected to the device body through a quick release key, and the quick release parts are inserted into the device body and the belt to fix the two. During disassembly, the quick release key must be removed before the belt can be removed from the device body, so the quick release key is easy to lose. In addition, the elastic deformation of the quick release parts is used to achieve disassembly and assembly. Repeated disassembly during use can easily cause wear of the quick release parts, thereby affecting the connection reliability and service life.

DETAILED DESCRIPTION

[0040] The embodiment of the present invention discloses a wearable device and a connecting device, which facilitates the disassembly of a connecting piece and a connected object and reduces the wear caused by repeated disassembly and assembly.

[0041] 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.

[0042] The connection device provided by the present invention is used to realize a detachable connection between a connecting member and a connected member, including but not limited to a detachable connection between a belt body and a device body, wherein the connecting member can be one of the belt body and the device body, and the other one is the connected member. In order to show the matching relationship more clearly, Figure 1-Figure 10 The example in which the connecting device is used in a wearable device is taken.

[0043] See also Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the assembly structure of a wearable device according to a specific embodiment of the present invention; Figure 2 for Figure 1 Schematic diagram of the assembly of the middle belt body and the connecting device; Figure 3 Schematic diagram of the internal structure of the connecting device.

[0044] In one embodiment, the connection device provided by the present invention includes a housing 100, a pusher 200, at least one rotating claw 300, a transmission structure 400 and a locking component 500. Among them, the housing 100 is the main support structure of the connection device, so as to facilitate the installation of the remaining components and provide a protective effect. The housing 100 is used to be fixedly connected with the connecting member, and its connection method is not specifically limited here. A mounting groove 110 is provided on one side of the housing 100, that is, the housing 100 is used to be connected to the side of the connected member to set the mounting groove 110. The pusher 200 is slidably arranged on the housing 100, and the rotating claw 300 is provided with at least one and is rotatably connected to the housing 100, and the inner end of the rotating claw 300 is arranged in the mounting groove 110, and the outer end extends out of the mounting groove 110. It can be understood that the inner end and the outer end of the rotating claw 300 are respectively located at the two ends of the rotating shaft of the rotating claw 300 relative to the housing 100. The inner end of the rotating claw 300 is connected to the pusher 200 through the transmission structure 400, and the sliding of the pusher 200 acts on the inner end of the rotating claw 300 through the transmission structure 400, thereby driving the rotating claw 300 to rotate open or retract, so that the outer end of the rotating claw 300 can be engaged with or disengaged from the slot 11 of the connected member. It should be noted that the rotating claw 300 rotates open or retracts inward, that is, when the rotating claw 300 is in the open state, the outer end of the rotating claw 300 can be engaged with the slot 11 of the connected member; and when the rotating claw 300 is in the retracted state, the outer end of the rotating claw 300 can be disengaged from the slot 11 of the connected member, that is, it can be inserted into or withdrawn from the slot 11. As required, the outer end of the rotating claw 300 can be engaged with the slot 11 of the connected member when the rotating claw 300 is retracted, and the outer end of the rotating claw 300 can be disengaged from the slot 11 of the connected member when the rotating claw 300 is opened, that is, can be inserted into or withdrawn from the slot 11. The locking member 500 is used to lock the rotating claw 300 at the corresponding engagement position.

[0045] By using the connection device provided by the present invention, the housing 100 can be fixed to the connection member for detachable connection with the connected member. During installation, the pusher 200 is pushed to slide relative to the housing 100, so that it drives the rotating claw 300 to rotate, so that the rotating claw 300 can be inserted into the slot 11 of the connected member, and then the pusher 200 slides in the opposite direction, thereby driving the rotating claw 300 to rotate in the opposite direction and engage with the slot 11, as shown in FIG. Figure 4 and Figure 5 As shown, the locking member 500 can lock the rotating claw 300 at the current position, thereby achieving effective connection between the connecting member and the connected member. Figure 6 and Figure 7 , push the pusher 200 to slide relative to the housing 100, which drives the rotating claw 300 to rotate so that the rotating claw 300 can release the engagement with the slot 11, and then pull out the rotating claw 300 to release the connection between the connector and the connected member. In summary, the connection device has a simple structure and is easy to assemble and disassemble. The engagement with the slot 11 is disengaged by rotating the rotating claw 300, and there is no need for the rotating claw 300 to deform. Therefore, repeated disassembly during use is not likely to cause wear of the rotating claw 300, thereby improving the connection reliability and extending the service life of the connection device.

[0046] In one embodiment, the transmission structure 400 includes a toothed shape 410 provided on the pusher 200 and a gear 420 provided at the inner end of the rotating claw 300. The gear 420 meshes with the toothed shape 410. When the pusher 200 slides, the gear rack moves, and the toothed shape 410 acts on the gear 420 to drive the gear 420 to rotate, so that the rotating claw 300 connected to the gear 420 rotates accordingly. It can be understood that the gear 420 and the rotating claw 300 can be either an integral structure or a split structure and connected by conventional fixing methods such as bonding and clamping. In the case where the gear 420 and the rotating claw 300 are an integral structure, a toothed structure is provided on the side wall of the inner end of the rotating claw 300, and the toothed structure is specifically provided with the rotating shaft of the rotating claw 300 as the center, and the part provided with the toothed structure can be used as the above-mentioned gear 420. It should also be noted that the gear 420 can have a toothed structure along the outer circumference, or can be provided with a toothed structure only within the range corresponding to the preset length. The transmission structure 400 adopts a method in which the teeth on the pusher 200 and the teeth on the rotating claw 300 are meshed, and the transmission is reliable and accurate. Specifically, the rotating claw 300 can be rotatably connected to the housing 100 through the gear 420, that is, the gear 420 is fixedly connected to the inner end of the rotating claw 300, and the gear 420 is rotatably connected to the housing 100, so the rotating claw 300 naturally uses the axis of the gear 420 as the rotation axis. In other embodiments, the rotating claw 300 and the gear 420 can also be separately connected to the housing 100 coaxially.

[0047] In one embodiment, a positioning column 120 is provided in the mounting groove 110, and the gear 420 is sleeved outside the positioning column 120 and can rotate around the positioning column 120. The positioning column 120 provides support and limit for the installation of the gear 420, so that it can rotate with the positioning column 120 as the rotation axis. Correspondingly, since the rotating claw 300 is connected to the gear 420, it can also rotate around it with the positioning column 120 as the rotation axis. The above arrangement is convenient for disassembly and assembly. In other embodiments, a gear shaft can also be provided at the center of the gear 420, a limiting hole is provided on the wall surface of the corresponding mounting groove 110, and the gear shaft is inserted into the limiting hole and rotates in the limiting hole to realize the rotation installation of the gear 420.

[0048] In other embodiments, the transmission structure 400 may also adopt a connecting rod mechanism, one end of the connecting rod mechanism is rotatably connected to the pushing member 200, and the other end is rotatably connected to the rotating claw 300. Then, the sliding of the pushing member 200 can also drive the rotating claw 300 to rotate through the action of the connecting rod mechanism.

[0049] In one embodiment, the locking member 500 includes an elastic member, which is disposed between the pusher 200 and the housing 100 and is used to provide a force to the pusher 200 to rotate the rotating claw 300 to the engaging position. By providing the elastic member, during installation, the pusher 200 is made to slide relative to the housing 100 by overcoming the force of the elastic member, and the elastic member is deformed accordingly, and the pusher 200 drives the rotating claw 300 to rotate, so that the rotating claw 300 can be inserted into the slot 11 of the connected member. When the rotating claw 300 is inserted into the slot 11, the pusher 200 is released, and the restoring force of the elastic member drives the pusher 200 to slide in the opposite direction, thereby driving the rotating claw 300 to rotate in the opposite direction and engage with the slot 11. At the same time, under the action of the elastic member, the rotating claw 300 is locked in the current engaging position, thereby realizing the effective connection between the connecting member and the connected member. During disassembly, the pusher 200 is pushed to slide relative to the housing 100 and overcome the force of the elastic member, and the pusher 200 drives the rotating claw 300 to rotate so that the rotating claw 300 can release the engagement with the slot 11, and then the rotating claw 300 can be pulled out to release the connection between the connector and the connected member. The locking member 500 adopts an elastic member, which can not only realize the reliable locking of the rotating claw 300, but also provide a reset force for the rotating claw 300. In addition, locking and unlocking will not cause deformation and wear of other parts, so non-destructive disassembly can be achieved. In other embodiments, the locking member 500 can also include a protrusion provided on one of the pusher 200 and the housing 100 and a groove provided on the other. When the pusher 200 is in the engaging position, the corresponding protrusion is inserted into the groove to lock, and when unlocking, the deformation of the protrusion or the groove is used to realize the separation of the two.

[0050] Furthermore, the elastic member can be a spring, or other elastic material member or structural member capable of providing restoring force as required. Specifically, the elastic member can be a compression elastic member, and the two ends of the compression elastic member are respectively against the push member 200 and the housing 100. When the sliding of the push member 200 drives the rotating claw 300 to rotate to the engaging position, the elastic member is compressed. After the push member 200 is released, the elastic member resets and pushes the push member 200 back to the initial position, and the rotating claw 300 rotates to the initial position accordingly. In other embodiments, the elastic member can also be a tensile elastic member, and the installation position of the elastic member relative to the push member 200 can be adjusted accordingly.

[0051] In one embodiment, please refer to Figure 3 , Figure 8 and Fig. 9 , a slide groove 130 is provided in the mounting groove 110, a position avoidance hole 140 is provided in the housing 100, and the pusher 200 includes a main body 210 and a support arm 220. Among them, one end of the main body 210 is provided in the slide groove 130 to slide along the slide groove 130, and the other end is penetrated in the position avoidance hole 140; the support arm 220 is connected to the side wall of the main body 210, and is used to cooperate with the rotating claw 300. By setting the slide groove 130, the sliding of the main body 210 relative to the housing 100 is limited and guided, so that the sliding is more stable. The position avoidance hole 140 on the housing 100 is convenient for the user to operate the pusher 200. Specifically, the other end of the main body 210 can extend out of the position avoidance hole 140, so as to facilitate operation. The support arm 220 cooperates with the rotating claw 300. When the transmission structure 400 adopts a gear 420, a tooth shape 410 is provided on the support arm 220 to mesh with the gear 420. It is understandable that the main body 210 and the support arm 220 can be either an integrated structure or a split structure, and are connected by a conventional fixing method. The pusher 200 adopts the above structure, which is convenient for users to operate and cooperate with the rotating claw 300.

[0052] In one embodiment, the rotating claw 300 includes a horizontal section 310 and a vertical section 320 connected to the inner and outer ends of the horizontal section 310 and facing opposite directions. The vertical section 320 located at the outer end faces the opening direction of the rotating claw 300, and the vertical section 320 located at the inner end is rotatably connected to the housing 100. When the rotating claw 300 adopts the above structure, when the rotating claw 300 is opened, the vertical section 320 at the outer end of the rotating claw 300 can be engaged with the slot 11 of the connected member, and when the rotating claw 300 is retracted, the vertical section 320 at the outer end of the rotating claw 300 can be disengaged from the slot 11 of the connected member. The rotating claw 300 adopts the above arrangement to facilitate its cooperation with the pusher 200 and the slot 11. In other embodiments, the vertical section 320 at the outer end of the rotating claw 300 can also face the retraction direction of the rotating claw 300. Of course, the rotating claw 300 is not limited to the above structure, and other conventional structures that can be engaged with the slot 11 can also be adopted as needed.

[0053] In one embodiment, claws for engaging with the slot 11 are respectively provided on opposite sides of the mounting slot 110, and at least one claw is a rotating claw 300. That is, by cooperating with the slot 11 with two claws arranged opposite to each other, the connected member is acted on from both ends, so that the force is more stable and the connection is more reliable. At least one of the two claws is a rotating claw 300, so as to meet the need for assembly and disassembly by rotation. In other embodiments, when the need for connection strength can be met by setting a rotating claw 300 on one side, a rotating claw 300 on only one side may also be provided.

[0054] In one embodiment, both claws are rotating claws 300, and the pusher 200 is arranged between the two rotating claws 300 and connected with the rotating claws 300 respectively through the corresponding transmission structure 400. That is, the reliable connection with the connected member is realized by the two rotating claws 300 arranged relatively. The rotating claws 300 on both sides can rotate, so it is more convenient to disassemble and assemble. The two rotating claws 300 correspond to the same pusher 200, with a simple structure and convenient operation. By pushing the pusher 200, the two rotating claws 300 can be driven to rotate accordingly. Of course, the actions of the two rotating claws 300 should be consistent, that is, they are all rotated to the engaging position or are all rotated to the disengagement position. When the transmission structure 400 includes a gear 420 and a tooth shape 410, the pusher 200 is respectively provided with a tooth shape 410 towards both sides of each rotating claw 300 to engage with the gear 420 on the corresponding rotating claw 300. The sliding of the pusher 200 drives the rotating claw 300 to rotate accordingly through the meshing of the tooth shape 410 and the gear 420 .

[0055] Furthermore, the two rotating claws 300 are symmetrically arranged in the sliding direction of the pushing member 200. By pushing the pushing member 200, the two rotating claws 300 can be driven to rotate open or retract synchronously accordingly, so that the outer ends of the two rotating claws 300 can engage with or disengage from the slots 11 of the connected member.

[0056] In other embodiments, one of the two claws arranged opposite to each other can be a rotating claw 300 and the other can be a fixed claw. Then, by rotating the rotating claw 300, such as when the rotating claw 300 is retracted, the two claws can move laterally as a whole in the slot 11 to disengage the fixed claw accordingly, and the claw can also be disengaged from the slot 11.

[0057] In one embodiment, the housing 100 may include a split upper housing 101 and a lower housing 102, and the upper housing 101 and the lower housing 102 are fixedly connected, and may be fixedly connected by dispensing. The split design facilitates the installation of the internal components. Specifically, the upper housing 101 is provided with an avoidance hole 140, one end of the pusher 200 is passed through the avoidance hole 140, and the mounting groove 110 may be provided on the lower housing 102.

[0058] In one embodiment, the housing 100 can be fixedly connected to the connector in the form of an insert to form a whole. Specifically, the side wall of the housing 100 has a protrusion 150 to be embedded in the connector.

[0059] Based on the connection device provided in the above embodiment, the present invention also provides a wearable device, which includes a device body 1, a belt body 2 and any one of the connection devices in the above embodiment, one of the device body 1 and the belt body 2 is fixedly connected to the housing 100 of the connection device, and the other is provided with a card slot 11. Since the wearable device adopts the connection device in the above embodiment, please refer to the above embodiment for the beneficial effects of the wearable device. Specifically, both sides of the device body 1 can be connected to the corresponding belt body 2 through the above connection device, or the above connection device can be provided on only one side of the device body 1 to connect to the belt body 2.

[0060] In one embodiment, the bottom and side of the card slot 11 have openings, and a first limiting rib 12 is provided at the opening on the side to abut against the rotating claw 300 for engagement, and a second limiting rib 13 is provided at the opening on the bottom surface to limit the rotating claw 300 to the card slot 11. It should be noted that the bottom surface here is only to distinguish it from the side of the card slot 11, and is not used to limit its position in the use state. By providing an opening on the bottom surface of the card slot 11, on the one hand, the rotating claw 300 can be disassembled and assembled by the opening on the side, and can also be selected to be disassembled and assembled by the opening on the bottom surface. On the other hand, the bottom surface opening facilitates the molding of the connected parts, such as demolding, thereby reducing the difficulty of processing. In other embodiments, the bottom surface of the card slot 11 may also not be provided with an opening. Specifically, the bottom surface of the card slot 11 can be a side close to the user's skin in the wearing state, thereby reducing the impact on the appearance of the wearable device and preventing misoperation caused by the exposed opening.

[0061] Furthermore, the connected part is the device body 1, that is, the card slot 11 is provided on the device body 1, and the corresponding connecting device is provided at one end of the belt body 2. The connecting device is provided at one end of the belt body 2, which will not affect the layout of the electronic components in the device body 1, and it is only necessary to provide the card slot 11 on the outer shell of the device body 1. Specifically, a lug 14 is provided on at least one side of the outer shell of the device body 1, and the lug 14 is provided with the above-mentioned card slot 11. The rotating claw 300 is inserted into the card slot 11 of the lug 14, so that the device body 1 and the belt body 2 can be connected.

[0062] In one embodiment, the wearable device can specifically be a wrist-worn device such as an ordinary watch, a smart watch or a smart bracelet, which is worn on the human wrist through a strap, or a head-worn device such as augmented reality glasses, virtual reality glasses, which is worn on the human head through a strap, or other devices worn on the human body through a strap.

[0063] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
