Description

Technical Field

[0001] This application belongs to the field of smart wearable device technology, and more specifically, to a detachable watch strap and a smart wearable device. Background Technology

[0002] In the smartwatch industry, the connection between the watch band and the watch body is usually achieved using spring bars. A spring bar is a shaft-like component used to connect the watch band and the watch body, with elastically retractable protrusions at both ends.

[0003] The specific method of spring bar connection is as follows: insert the spring bar into the connection hole at the end of the watch strap, and then press the protrusions at both ends of the spring bar to make it shrink and snap into the mounting holes on both sides of the watch lugs. The watch strap and the main body are fixedly connected by the cooperation of the protrusions and the mounting holes.

[0004] However, the spring bar connection method has obvious drawbacks: because the protrusions at both ends of the spring bar are elastic and small in size, special tools must be used to press the protrusions to make them stretch when installing or removing the watch band. This not only makes the operation cumbersome and increases the difficulty for users, but also makes it impossible to quickly install or remove the watch band, making it difficult to meet users' needs for convenient replacement of smartwatch watch bands in daily life.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] The present application will now describe a quick-release watch strap structure provided in an embodiment.

[0025] See Figures 1 to 4 The quick-release structure of the watch strap 8 mainly includes the lug 1, the strap base 2, the locking lever 3, and the operating block 5. The structural design and functional linkage logic of each component are as follows: The lug 1 connects to the housing 7 of the main body of the device. The lug 1 is provided with a receiving groove 11 whose groove depth is parallel to the length of the strap 8. The receiving groove 11 is a groove structure used to accommodate the connecting seat 2. On the two opposite side walls of the receiving groove 11, a locking groove 111 is formed by recessing along the groove depth direction perpendicular to the receiving groove 11. The locking groove 111 is specifically used to cooperate with the subsequent locking rod 3 to achieve locking and fixation.

[0026] The connecting seat 2 is an intermediate carrier connecting the watch strap 8 and the housing 7. However, the connecting seat 2 is connected to the watch strap 8. In other words, during the process of installing or removing the watch strap 8, both the watch strap 8 and the connecting seat 2 are connected together. The shape of the connecting seat 2 is precisely matched with the receiving groove 11 of the lug 1, and it can be smoothly inserted from the opening of the receiving groove 11 and accommodated in the groove.

[0027] The locking rod 3 is slidably connected to the connecting seat 2. There are two locking rods 3, which are slidably inserted into the two slots 111 respectively, so as to lock the connecting seat 2 into the receiving slot 11.

[0028] The operating block 5 is movably mounted on the connecting seat 2. The operating block 5 and the locking rod 3 are connected by a lock-and-disengage transmission. The lock-and-disengage transmission connection allows the operation rod and the locking rod 3 to have a locked state and a disengaged state. The locked state is the process of moving the operating block 5 to allow the locking rod 3 to be inserted into the slot 111. The disengaged state is the process of moving the operating block 5 to allow the locking rod 3 to leave the slot 111.

[0029] In summary, by utilizing the cooperation between the operating lever and the locking lever 3, the quick assembly and disassembly of the watch strap 8 and the lug 1 are achieved, thus facilitating the replacement of the watch strap 8 for smartwatches or smart wearable devices.

[0030] Based on the aforementioned assembly and disassembly process, it can be seen that the assembly and disassembly process mainly involves two processes: the first is that the connecting seat 2 is embedded in the receiving groove 11, and the second is that the locking rod 3 is embedded in the slot 111.

[0031] In some embodiments, in order to facilitate the insertion of the strap 2 into the receiving groove 11, an opening is designed on the side wall of the receiving groove 11 away from the inner side of the strap 8 (i.e. away from the user's wrist) to facilitate the insertion and removal of the strap 2. Alternatively, the operating block 5 can be set at the opening of the receiving groove 11 to reduce the volume of the lug 1, thereby improving the wearing stability of the wearable device.

[0032] In some embodiments, to ensure the locking rod 3 smoothly enters the slot 111 during the insertion process, the following configuration is adopted: First, auxiliary magnets 6 with opposite polarities are embedded on the mating surfaces of the connecting seat 2 and the bottom of the receiving groove 11, forming a stable magnetic attraction force. When the connecting seat 2 is inserted into the receiving groove 11, the magnetic attraction force provides auxiliary fixation for the connecting seat 2, limiting the displacement of the connecting seat 2 parallel to the centerline of the receiving groove 11, and reducing the alignment difficulty of the locking operation.

[0033] Secondly, limiting grooves 112 are provided on the two opposite side walls of the receiving groove 11. The limiting grooves 112 are set on the side wall near the opening of the receiving groove 11 and extend along the center line of the receiving groove 11 (i.e. the length direction of the watch strap 8). Correspondingly, the two opposite side walls of the connecting seat 2 are integrally formed with limiting rails 21 that are adapted to the limiting grooves 112. During installation, the limiting rails 21 can slide into the opening of the limiting grooves 112 and slide smoothly along the length direction of the limiting grooves 112, which can limit the displacement of the connecting seat 2 parallel to the thickness direction of the watch strap 8 and reduce the alignment difficulty of the locking operation.

[0034] In summary, the three improvements mentioned above can be used independently or in combination, but the combination is not arbitrary. For example, the cooperation between the limiting slide groove 112 and the limiting slide rail 21, and the opening of the receiving groove 11, are usually not used together. Based on this, there are several combination methods: First, the auxiliary magnet 6, the limiting slide groove 112 and the limiting slide rail 21 are combined; Second, the auxiliary magnet 6 and the opening of the receiving groove 11 are combined.

[0035] In this embodiment, considering the ease of installation and the simplicity of the structure, the second combination method is preferred. However, in the second combination method, since the magnetic attraction force of the auxiliary magnet 6 is not very large, there may be a situation where the connecting seat 2 wobbles left and right in the receiving groove 11. Based on this, it is necessary to limit this left and right wobbling, but without affecting the connecting seat 2 from entering the receiving groove 11 through the opening of the receiving groove 11. This will allow the outer wall of the connecting seat 2 to abut against all the side walls of the receiving groove 11. Through the surface-to-surface fitting structural design, it is ensured that there is no wobbling after connection, thus improving the overall stability.

[0036] In other embodiments, if there are other components that need to be operated on the connecting seat 2, and the receiving groove 11 has two opposite side wall openings, then only the first combination method can be used.

[0037] See Figure 5 Based on the aforementioned second combination method, the connecting seat 2 is provided with an installation channel 22. The core function of the installation channel 22 is to provide installation and working space for the locking rod 3, the operating block 5 and the transmission structure between them. At the same time, the installation channel 22 is provided with a rod window 221 and an operating window 222 to provide smooth movement space for the locking rod 3 to pass through and retract. Meanwhile, the operating window 222 is located on the connecting seat 2 at the end opposite to the inner side of the watch strap 8, that is, at the opening of the receiving groove 11, so that the operating block 5 is partially exposed, ensuring that the user can directly contact and operate the operating block 5, and providing operating space for subsequent state switching.

[0038] See Figure 6As mentioned above, the operating block 5 and the locking rod 3 are connected by a locking-off transmission. There are many factors to consider in order to realize this transmission connection. For example, whether one operating block 5 drives one locking rod 3 or one operating block 5 drives two locking rods 3. Also, whether the operation block 5 and the locking rod 3 are connected by abutment or linkage transmission. Based on these factors, it is preferable that one operating block 5 drives two locking rods 3 and that the operation block 5 and the locking rod 3 are connected by abutment transmission.

[0039] Based on this, the operating block 5 is formed with a locking guide surface 511. The locking guide surface 511 has a far stop position 5111 and a near stop position 5112. At the far stop position 5111, the locking guide surface 511 is closer to the side wall where the slot 111 is located. At the near stop position, the locking guide surface 511 is farther from the side wall where the slot 111 is located. The locking guide surface 511 abuts against the side of the two locking rods 3 that are close to each other. A closing spring 4 is provided between the two locking rods 3. The closing spring 4 is used to apply a force to the two locking rods 3 to bring them closer together, so as to realize the transmission form of the cam mechanism between the operating block 5 and the locking rods 3, thereby realizing the operation block 5 driving the locking rods 3 to enter and exit the slot 111.

[0040] Based on the aforementioned abutment transmission, there are two types of cams in the cam mechanism: moving cams and disc cams. Considering the simplicity of the structure, the moving cam method will be adopted, and the operation block 5 will be set in a sliding manner.

[0041] Based on the sliding setting of the operating block 5, in order to improve the smoothness of the two locking rods 3 separating by the operating block 5, an opening guide surface 31 adapted to the locking guide surface 511 is also machined on the inner side wall of the locking rod 3. The opening guide surface 31 is inclined.

[0042] Since the movement of the locking rod 3 is driven by the movement of the operating block 5, in order to keep the locking rod 3 from extending out of the installation channel 22 before installation, or to keep the locking rod 3 stably in the slot 111 after installation, that is, to prevent the operating block 5 from sliding due to bumps when it is not necessary to move the operating block 5.

[0043] See Figures 7 to 8 Specifically, the operating block 5 includes a stop rod 51, a toggle part 52, and a floating spring 53. The stop rod 51 is slidably disposed within the mounting channel 22, and its outer wall is machined with the aforementioned locking guide surface 511. The toggle part 52 extends to the operating window 222, serving as the user's direct control end. The two ends of the floating spring 53 are connected to the stop rod 51 and the toggle part 52, respectively. Normally, the floating spring 53 causes the toggle part 52 to partially float out of the operating window 222, improving user touch recognition and ease of operation.

[0044] Meanwhile, to match the structure of the operating block 5, the operating window 222 is divided into a locking area 2221, a middle touch area 2222, and a separation area 2223 along the sliding direction of the operating block 5. The locking area 2221 corresponds to the position of the operating block 5 in the locked state, and the separation area 2223 corresponds to the position of the operating block 5 in the separated state. The middle touch area 2222 is a transition area and is provided with an anti-push block 22221. The anti-push block 22221 does not completely cover the space of the middle touch area 2222. In the locking area 2221 and the separation area 2223, the two inner walls of the anti-push block 22221 perpendicular to the sliding direction of the operating block 5 abut against the toggle part 52 to restrict the movement of the operating block 5.

[0045] Switching between different states requires a compound action of "pressing-sliding-rebounding". Taking the switch from the separated state to the locked state as an example: Initially, the toggle part 52 is pushed out by the floating spring 53 and forms a limit with the anti-push block 22221. At this time, it cannot slide directly. When the user presses the toggle part 52 to compress the floating spring 53, the toggle part 52 sinks and is released from the limit. Only then can it be pushed from the separated area 2223 through the middle touch area 2222 to the locked area 2221. After releasing the press, the floating spring 53 drives the toggle part 52 to rebound and reset, and it is again in contact with the anti-push block 22221 for the limit. The operating block 5 is stable at the far rest position 5111, and the locking rod 3 is simultaneously extended and locked. Conversely, the process of switching from the locked state to the separated state is completely the same. The same action logic is used to achieve reliable bidirectional switching.

[0046] In other embodiments, the operation block 5 can also be damped and slidable to limit the sliding of the operation block 5 due to the absence of collisions.

[0047] Based on the quick-release structure of the watch strap 8 described above, the installation and removal process of the watch strap 8 is as follows: Install the watch strap 8: Align the strap base 2 with the lug 1 receiving groove 11, so that the limiting slide rail 21 of the strap base 2 is aligned with the limiting slide groove 112 of the lug 1 and inserted. At this time, the strap base 2 is attracted to the auxiliary magnet 6 at the bottom of the receiving groove 11, achieving precise pre-positioning. Then push the operating block 5 to slide from the separation area 2223 to the locking area 2221. The locking guide surface 511 of the operating block 5 pushes the locking rod 3 outward through the opening guide surface 31 until the outer end of the locking rod 3 is inserted into the slot 111 of the lug 1. At this time, the operating block 5 is stably in the near rest position 5112, and the watch strap 8 and the housing 7 are locked and fixed.

[0048] To remove the watch strap 8: Press and slide the operating block 5 from the locking area 2221 to the separating area 2223. As the operating block 5 moves, the contact position between the locking guide surface 511 and the locking rod 3 changes, and the force of the closing spring 4 is gradually released, driving the locking rod 3 to retract inward and disengage from the lug 1 slot 111. Continue to slide the operating block 5 to the separating area 2223 and keep it stable. At this time, the locking relationship between the strap seat 2 and the lug 1 is released, and the strap seat 2 can be pulled out from the receiving slot 11 to complete the removal of the watch strap 8.

[0049] In addition to the aforementioned quick-release structure of the watchband 8, this application also provides a smart wearable device, specifically a smartwatch or a smart bracelet. The smart wearable device includes a main body and a watchband 8. The main body includes a housing 7, and the housing 7 and the watchband 8 are connected via the aforementioned quick-release structure of the watchband 8. The specific structure of the quick-release structure of the watchband 8 is described in the foregoing embodiments and will not be repeated here.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
