detailed description

In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be described in further detail below with reference to the accompanying drawings.

In order to facilitate understanding of the wearable device provided in the embodiments of the present application, firstly, it is explained that the wearable device of the present application may be an electronic watch, a bracelet, or a wearable device of a hanging type. The wearable device includes a body of the wearable device and a sub-fixture. The body of the wearable device and the sub-fixture can correspond to different wearable devices and have different structures. The body of the wearable device is a dial, and the sub-fixation is a strap. When the wearable device is a bracelet, the body of the wearable device is the body of the bracelet, and the sub-fixation is a watch strap. When the wearable device is a hang-and-wear type wearable device, the body of the wearable device is a body with electronic functions, and the sub-fixture is a lanyard.

To facilitate understanding, the wristband is used as an example to describe the wearable device. As shown in FIG. 1, FIG. 1 shows the main structure of the bracelet. The bracelet includes a bracelet body 10 and a strap 20. The number of the strap 20 is two, and the two straps The connection method of 20 may be a connection method such as a lock in the prior art. In this application, in order to facilitate charging of the bracelet, a charging plug 11 is provided on the bracelet body 10, and the number of the charging plug 11 may be one or two. In the structure shown in FIG. 1, a charging plug 11 is used, and the charging plug 11 is correspondingly connected to one of the watch bands 20, and the other watch band 20 is connected to the bracelet body 10 using the connection method in the prior art. As shown in FIG. 2, when there are two charging plugs 11, the two charging plugs 11 respectively correspond to the two watch bands 20. As shown in FIG. 3, when charging, the charging plug 11 is connected to the charger to realize external charging. However, whether two charging plugs 11 or one charging plug 11 is used, the connection method with the watch band 20 is the same. The following uses a charging plug 11 as an example to describe the connection method of the wristband body 10 and the watch band 20 in detail.

In the prior art, the strap and the plug in the wearable device are connected with an interference fit. The reliability of the entire connection structure is relatively poor, and it is easy to loosen after long-term use or stress, causing the smart watch or bracelet to fall off. For this reason, the embodiments of the present application provide a new connection method, as shown in FIG. 4, which is realized by a plug-in structure when the bracelet body 10 is connected to the watch band 20. The plug-in structure includes two parts, one part is the charging plug 11 provided on the bracelet body 10 and the other part is the corresponding jack 21 provided on the wristband 20, and the jack 21 is used for charging plug 11 Plug. First of all, for the charging plug 11, it can choose different types of charging plug 11, such as a USB plug, or Type-C plug, or a plug known in the prior art, but no matter which plug is used, it can be applied in this Application examples. When connected to the wristband body 10, the charging plug 11 is assembled in the shell parts at both ends of the wristband body 10, and is sealed and fixed by glue, and the glue also plays a waterproof role, or the charging plug 11 is injection molded into the bottom shell In this application, the assembly method of the charging plug 11 and the bracelet body 10 is not limited. The charging plug 11 is electrically connected by the FPC and the PCB assembly inside the housing. When charging, similar mobile phones use a cable with a Type-C plug or a USB plug for charging. In addition, due to the directionality of the USB plug when it is inserted, some foolproof design is required. As shown in FIG. 3, some foolproof protrusions 112 are provided on the charging plug 11 to ensure that the USB plug is inserted into the charging dock , Will not be reversed. The Type-C plug does not have positive and negative limits, so there is no need to make foolproof settings.

For the jack 21, the jack 21 is a hole provided at one end of the watch band 20 for connecting with the bracelet body 10. When the strap 20 is connected to the bracelet body 10, the charging plug 11 is inserted into the jack 21, and when the charging plug 11 is provided with a foolproof protrusion 112, the corresponding jack 21 is provided with a foolproof The protrusion 112 cooperates with the notch.

In order to ensure that the charging plug 11 can be stably inserted into the jack 21, the wearable device provided by the embodiment of the present application further provides a locking device and an unlocking device, wherein the locking device is used to insert the charging plug 11 into the jack At 21, the charging plug 11 is locked to improve the stability effect of the wearable device body when inserted into the sub-fixture. The unlocking device is used to unlock the charging plug 11 when the bracelet body 10 and the watch band 20 need to be disassembled, so that the charging plug 11 can be pulled out of the jack 21. Different ways of implementing locking and unlocking may be adopted, and the locking device and the unlocking device will be described as examples below.

First, for the locking device, it is necessary to lock the charging plug 11 and the watch band 20. Therefore, when installing, the locking device includes two parts, which are respectively disposed on the charging plug 11 and the watch band 20. Wherein, a part provided on the charging plug 11 is the first clamping structure, and a part provided on the watch band 20 is the second clamping structure 30. The second clamping structure 30 extends into the jack 21, and the second clamping structure 30 engages and locks with the first clamping structure provided on the charging plug 11, and the first clamping structure and the second clamping structure The structure can slide relatively. When the charging plug 11 is inserted into the first setting position, the first clamping structure and the second clamping structure 30 are engaged. The first setting position refers to a position where the charging plug 11 is inserted into the jack 21, the first clamping structure can be engaged with the second clamping structure, the first setting position is based on the first clamping structure and Set by the second clamping structure. When the first clamping structure or the second clamping structure slides to the second set position, the locking device unlocks the charging plug 11. The second setting position is a position where the first clamping structure and the second clamping structure are disengaged. The second setting position is set according to the first clamping structure and the second clamping structure.

For the first clamping structure and the second clamping structure 30, different structural forms may be adopted, but the first clamping structure and the second clamping structure 30 need to cooperate with each other to achieve engagement. Referring to FIG. 5 and FIG. 6, the first clamping structure and the second clamping structure 30 are matched by a hook and a groove. The first clamping structure is a first clamping groove 111 provided on the charging plug 11, and the second clamping structure 30 includes a second clamping hook 32. As shown in FIG. 6, taking a USB plug as an example, a surface of the USB plug is provided with a recessed first card slot 111, and the first card slot 111 is located between two charging electrodes on the USB plug . In addition, a gap for avoiding the second hook 32 is provided at the end of the USB plug between the two electrodes. When the second hook 32 engages with the first slot 111, the second The hook 32 is inserted into the gap of avoidance, and is engaged with and fixed with the first clamping slot 111, so that the space in the jack 21 can be reasonably utilized, and the space occupied by the entire locking device is reduced. In addition, the first clamping structure may adopt other structures besides the first clamping groove 111 described above, for example, the first clamping structure adopts a hook structure, and at this time, the first clamping structure is a first card Hook, and the first hook is fixedly connected with the charging plug 11.

When the locking device is specifically provided, since the first clamping structure adopts the hook body or the groove body structure, it is a static structural component. In order to be able to unlock, the second hook 32 adopts a structure that can slide relative to the first slot 111 to achieve engagement and unlocking with the first slot 111. The corresponding specific implementation manners may adopt different manners. For example, in the structure shown in FIG. 5 and FIG. 6, the relative movement manner adopted by the second hook 32 is sliding. The second hook 32 is an L-shaped structure, and the vertical portion 322 is used for sliding assembly with the watch band 20, and the end of the horizontal portion 321 is provided with a bent hook body to engage with the first clamping groove 111 Together. In order to assemble the second hook 32, a through hole 22 communicating with the insertion hole 21 is provided on the watch band 20, and the opening of the through hole 22 away from the insertion hole 21 is provided on the inner surface of the watch band 20. The inner surface refers to a surface that fits the human skin when the wearable device is worn. When assembling the second hook 32, the vertical portion 322 of the second hook 32 is inserted into the through hole 22 and can slide, while the horizontal portion 321 is located in the insertion hole 21 and is used to communicate with the first hook 111 or the first hook Hook fit.

5 and 6, in order to drive the second hook 32 to slide, the second clamping structure 30 further includes a first elastic member 31 and a limiting member. Wherein, the first elastic member 31 is used to drive the second hook 32 to slide in the direction of engaging with the first hook or the first slot, so that the second hook 32 is engaged with the first hook or the first slot The direction in which the first elastic member 31 drives the second hook 32 to slide is the direction in which the second hook 32 engages with the first hook or the first slot 111, and the limiting member is used to limit the sliding distance To prevent the second hook 32 from sliding past the position. The defined position of the limiting member should be able to ensure that the charging plug 11 can overcome the elastic force of the first elastic member 31 to drive the second hook 32 in the opposite direction (and the first elastic member 31 drives the second hook 32 Slide in the direction opposite to the direction of engagement).

The first elastic member 31 may use different elastic members to push the second hook 32 to slide. If the first elastic member 31 is an elastic piece, and one end of the elastic piece is in pressure contact with the second hook 32 and the other end is in pressure contact with the side wall of the insertion hole 21; or the first elastic member 31 is a compression spring, a compression spring One end is in pressure contact with the second hook 32 and the other end is in pressure contact with the side wall of the insertion hole 21. Or use different elastic structures such as tension springs. As shown in FIG. 5, FIG. 5 shows that the structure of the elastic sheet is used to drive the second hook 32. The elastic piece is a U-shaped bent elastic piece, and the two ends of the elastic piece are respectively provided with claws bent on the outer side of the outer elastic piece, wherein one end of the claw is fitted on the side wall of the socket 21 The claw at the other end is mounted on the horizontal portion 321 of the second hook 32. It can be seen from FIG. 6 that the installed elastic sheet is entirely located in the jack 21 and occupies a part of the space in the jack 21, so a part of the space needs to be reserved in the jack 21 to set the elastic sheet, and the setting should be guaranteed The elastic piece does not affect the insertion of the charging plug 11. In an implementable solution, a mounting groove may be provided on the side wall of the jack 21 so that the cross section of the jack 21 has a shape similar to a "convex" shape, so that the charging plug 11 is inserted into the through hole 21 The inside will not be affected by the elastic sheet. It should be understood that only a few specific structures of the first elastic member 31 are listed above, and the structural members that provide elastic force known in the prior art may also be used in the embodiments of the present application. For the material of the first elastic member 31, a metal with elasticity, such as metal such as steel, iron, copper, or a material with elasticity, can be selected. When the charging plug 11 is inserted into the jack 21, and the charging plug 11 presses the second hook 32 upward (taking the placement direction of the bracelet shown in FIG. 6 as a reference direction), the second hook 32 is elastic under the driving The sheet is compressed, and when the charging plug 11 moves to the first set position, the second hook 32 is opposed to the first slot 111. As shown in FIG. 7, under the elastic force provided by the compressed elastic sheet, the second hook 32 slides down and falls into the first clamping slot 111, the elastic sheet bounces, completes the locking action, and passes the The cooperation of the part of the two hooks 32 located in the first slot 111 and the first slot 111 locks the charging plug 10 and the watch band. When unlocking, the second hook 32 is pressed by the unlocking device, and the second hook 32 slides upward and presses the elastic piece to deform again. When the second hook 32 is pushed out of the first slot 111, the second hook 32 is out of contact with the first slot 111, and at this time, the charging plug 20 and the strap 20 are unlocked, and the external force The charging plug 10 can be pulled out from the jack 21. After that, the unlocking device is released, and under the elasticity of the elastic sheet, the second hook 32 returns to the initial state.

For the limiter, the limiter is a rigid bracket 33, and the rigid bracket 33 is locked in the watch band 20. As shown in FIGS. 5 and 6, FIG. 5 shows a specific structure of the rigid bracket 33, and the rigid bracket 33 includes a pressing surface for pressing contact with the second hook 32. In addition, one end of the rigid bracket 33 has an escape notch 332 for the second hook 32 to pass through, and the other end is provided with two claws 331 for fitting in the jack 21. During specific assembly, the plug The side wall of the hole 21 is provided with a locking groove that cooperates with the two claws 331, and at the same time, the side wall inside the socket 21 is provided with a locking groove that cooperates with the protruding ends provided on both sides of the avoidance notch 332 , So that the entire rigid bracket 33 is fixed in the slot. In order to limit the second hook 32, the vertical portion 322 of the second hook 32 is provided with a protrusion that cooperates with the escape notch 332, or the vertical portion 322 adopts a stepped structure. In order to allow a part of the vertical portion 322 to pass through the avoidance notch 332, another part is caught by the rigid bracket 33 to achieve the limit. During the specific assembly, the escape notch 332 corresponds to the through hole 22. First, the second hook 32 is inserted into the insertion hole 21 from the through hole 22, and then, the rigid bracket 33 is inserted into the insertion hole 21 and fixed. When the rigid bracket 33 is inserted into the insertion hole 22, the avoiding notch 332 is sleeved on the vertical portion 322, and a step structure cooperating with the avoiding notch 332 is provided on the vertical portion 322 to restrict the sliding position of the second hook 32. In addition to the specific rigid bracket 33 shown above, the limiter can also adopt other structures, for example, the rigid bracket 33 is only a plate-like structure with an escape gap, corresponding to the two opposite sides in the socket 21 A slot for fixing the plate-like structure is provided on the wall, and the rigid bracket 33 can be fixed when the plate-like structure is inserted into the slot. The rigid bracket 33 can be made of different materials, such as aluminum, iron, steel, or other metal materials when it is specifically installed. Of course, it can also be made of rigid plastic and other scrap metal materials with a certain rigidity.
