Description

Technical Field

[0001] This solution belongs to the field of electronic equipment technology, specifically involving a quick-release structure for a watchband in an electronic product. Background Technology

[0002] Watch straps for electronic products are supporting components for wrist-worn wearable electronic products such as smartwatches, smart bracelets, and sports watches. They are mainly used to achieve a stable connection and secure wearing between the product body and the wearer's wrist. Through differentiated designs in terms of materials, specifications, and styles, they can be adapted to different wrist sizes and usage scenarios, making them an indispensable part of wrist-worn wearable electronic products.

[0003] Currently, most wrist-worn wearable electronic products feature detachable watch straps, allowing users to freely change straps of different materials, specifications, and styles for different scenarios such as business commuting, sports and fitness, and leisure and social activities. This satisfies the needs for personalized dressing and scenario-based functional adaptation, and is compatible with a wide range of universal watch strap accessories.

[0004] A watch with a detachable strap is disclosed in the existing publication (announcement) number CN113273776A, which includes a dial, a strap, and a release button. The dial has a snap-fit ​​groove and a release channel communicating with the snap-fit ​​groove. The strap is disposed in the snap-fit ​​groove and snaps into the dial. The release button is disposed in the release channel and is used to slide into the snap-fit ​​groove to release the strap from the dial.

[0005] For example, the aforementioned detachable watch strap uses a buckle structure to detachably connect the strap to the watch body. However, to achieve the coordination of the locking and unlocking actions, the core locking component of this type of structure needs to be made of a material with elastic deformation capabilities. This allows the strap to complete the cycle of locking, unlocking, and deactivation through its own deformation. During repeated pressing of the release button and frequent disassembly and reassembly of the strap, the deformable part of the buckle will continuously bear cyclic stress and reciprocating deformation. After long-term use, it is prone to material fatigue and irreversible plastic deformation, which directly leads to a significant decrease in the buckle's springback and reset capability and a reduction in the locking preload. This can result in minor issues such as loose connection between the strap and the watch body and rattling noises, or even serious issues such as failure of the locking structure and accidental detachment of the strap. Summary of the Invention

[0006] This invention provides a quick-release structure for watch straps in electronic products to improve the connection reliability between the watch strap and the watch body.

[0007] This invention provides a quick-release structure for a watch strap in an electronic product, comprising a watch body and a watch strap. The watch body has a slot, and one end of the watch strap has a buckle that can slide along the slot. It also includes a locking assembly, which comprises: The watch body has a sliding groove, one end of which penetrates the inner wall of the slot. The snap-fit ​​component is located in the sliding groove, and one end of the snap-fit ​​component extends into the slot. An elastic element is provided in a sliding groove, with one end of the elastic element abutting against the sliding groove and the free end fixedly connected to a snap-fit ​​element. The locking groove is formed on the buckle, and the locking groove and the buckle groove are coaxially opposite each other.

[0008] The principle and effect of this solution are as follows: A sliding connection is formed between the slot in the watch body and the buckle at the end of the watch strap. When the buckle slides along the slot, it resists the locking element, compressing the elastic element and generating a pre-tightening force. When the buckle slides to the preset locking position, the locking groove aligns with the locking element, and the elastic element releases the pre-tightening force, pushing the locking element to slide, causing its end extending into the slot to embed into the locking groove, thus restricting the buckle's sliding freedom and locking the watch strap to the watch body. Disassembly only requires sliding the buckle in the opposite direction to completely remove the locking element from the locking groove, allowing for tool-free and quick disassembly of the watch strap. The elastic element in this solution only provides pre-tightening force and does not participate in the locking force, avoiding material fatigue and locking failure problems caused by repeated deformation in traditional elastic buckles, thus improving the connection reliability between the watch strap and the watch body.

[0009] Furthermore, the snap-fit ​​component includes a slider and a protrusion. The slider is disposed in a groove and is fixedly connected to the protrusion. One end of the protrusion is disposed in a slot for engaging with a locking groove.

[0010] The principle and effect of this solution are as follows: the snap-fit ​​component is set as a split structure with the slider and the protrusion fixedly connected. The slider receives the elastic force drive and sliding guide of the elastic element, and the protrusion undertakes the locking cooperation with the locking groove. When the elastic element pushes the slider to slide along the groove, it drives the protrusion to move axially synchronously, so as to realize the protrusion embedding into the locking groove to complete the locking.

[0011] Furthermore, the elastic element is a spring.

[0012] The principle and effect of this solution is that it can provide a stable linear preload for the snap-fit ​​components.

[0013] Furthermore, the snap-fit ​​assembly also includes a pin; the watch body has a receiving groove, the pin is located in the receiving groove, and the free end of the pin is located in the snap-fit ​​groove; both the slider and the protrusion are cylindrical structures, and the outer wall of the slider has a threaded guide groove, and the outer wall of the protrusion has a threaded locking groove; the free end of the pin abuts against the threaded guide groove to restrict the spiral movement of the slider; the inner wall of the locking groove has an external thread that mates with the threaded locking groove.

[0014] The principle and effect of this solution are as follows: Since the locking structure relies solely on the axial insertion of the locking component into the locking slot, the axial movement of the locking component may still occur during daily wear of the watch due to movement, impact, or vibration. In some cases, the locking component may even accidentally pop out of the locking slot against the pre-tightening force of the elastic element, causing the locking to fail. This solution uses a pin with its end extending into a slot within the receiving groove of the watch body. This works in conjunction with a cylindrical slider with a threaded guide groove on its outer wall and a cylindrical protrusion with a threaded locking groove on its outer wall. When the elastic element pushes the slider to move axially along the groove, the free end of the fixed pin always contacts and limits the slider's axial linear movement with the threaded guide groove on its outer wall. This restricts the slider's axial linear movement while simultaneously causing it to rotate circumferentially, creating a helical feed motion. This, in turn, drives the protrusion fixed to the slider to rotate synchronously in a helical motion. The threaded locking groove on the outer wall of the protrusion and the mating internal thread on the inner wall of the locking groove form a threaded connection. Based on axial insertion locking, the threaded engagement creates dual axial and circumferential limiting, avoiding the wobbling and shifting problems common in traditional straight-insertion structures and improving the stability of the connection between the watch strap and the watch body.

[0015] Furthermore, the latching assembly also includes a lever, which is disposed in the receiving groove, with one end of the lever being coaxially and fixedly connected to the pin, and the free end of the lever being disposed outside the receiving groove.

[0016] The principle and effect of this solution are as follows: the free end of the lever protrudes outside the receiving groove to form a manual control end; in the normal locked state, the pin is in the initial position, driving the protrusion to complete the threaded engagement and locking with the locking groove; when removing the watch strap, moving the lever towards the locking groove causes the pin to move synchronously, and through the cooperation of the pin and the threaded guide groove, it drives the slider to move axially in the opposite direction and rotate synchronously, thereby driving the protrusion to rotate in the opposite direction, disengaging it from the threaded engagement structure of the locking groove, thus completing the unlocking. This solution solves the problem of difficulty in quickly and manually unlocking after threaded locking by the cooperation of the lever and the pin, allowing for convenient unlocking without tools.

[0017] Furthermore, the receiving groove is provided with a guide groove for guiding the lever.

[0018] The principle and effect of this solution are as follows: the guide groove is used to provide positioning and guidance for the movement of the lever, so as to prevent it from being dislodged or misaligned.

[0019] Furthermore, the outer wall of the slider is provided with a release groove, one end of which extends to the end face of the slider, and the free end is connected to the threaded guide groove.

[0020] The principle and effect of this solution are as follows: the axial release groove connected to the threaded guide groove provides a movement path for the limit pin to release. After the protrusion is screwed into the locking groove, the lever is manually moved to move the free end of the pin along the release groove and move out to the outside of the end of the slider, so as not to contact the slider and release the limit constraint on the slider.

[0021] Furthermore, the release groove is arranged parallel to the central axis of the slider.

[0022] The principle and effect of this solution is that the extension direction of the release groove is exactly the same as the axial sliding direction of the slider.

[0023] Furthermore, the spring coil is fixedly connected to a locking member, the pin has a through locking hole, and one end of the locking member is used to be inserted into the locking hole.

[0024] The principle and effect of this solution are as follows: by setting a locking element on the spring coil and opening a corresponding locking hole on the pin, when the lever drives the pin to move into place, the locking element can be inserted into the locking hole to fix the spring coil and the pin relative to each other. If the protrusion is vibrated and rotates in the opposite direction during wear, the locking element will rotate with the slider and drive the spring to twist, so that the spring changes from an ordinary compression spring to a torsion spring and stores elastic potential energy. This potential energy then drives the slider and the protrusion to rotate in the opposite direction, tightening the protrusion back into the locking groove, thereby preventing the protrusion from accidentally slipping out. It uses a single spring to push the slider at the same time and can also store energy by twisting to prevent the protrusion from dislodging, further improving the connection stability between the strap and the watch body.

[0025] Furthermore, the locking member has an "L" shaped structure, with one end fixed to the spring and the free end engaging with the locking hole.

[0026] The principle and effect of this solution are as follows: one end of the "L"-shaped locking component is fixed to the spring coil, while the other end, which extends vertically, allows it to be smoothly inserted into the locking hole. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 The quick-release watch strap structure of the electronic product according to the embodiments of the present invention is described in detail. It can be widely used in various wrist-worn wearable electronic products such as smartwatches, electronic bracelets, and sports watches, meeting users' needs for convenient watch strap replacement and stable wear.

[0033] Please see Figure 1 and Figure 2In this embodiment, the watch body 1 is the main shell of the electronic product, and the watch strap 2 is a flexible wearing strap adapted to the watch body 1. A set of structures for connecting the watch strap 2 is provided at each of the opposite ends of the watch body 1. The two sets of structures are symmetrically arranged, and the two ends of the watch strap 2 are respectively connected to the corresponding structures at both ends of the watch body 1. The following is a detailed description using a single connection structure as an example. A slot 11 is provided at the end of the watch body 1. The slot 11 specifically adopts a T-shaped through-slot structure. One end of the watch strap 2 is integrally formed or fixedly connected to a buckle 21. The buckle 21 is a T-shaped buckle that matches the shape and size of the slot 11. The buckle 21 can slide into or out of the slot 11 along the axial direction, thereby achieving basic pre-assembly of the watch strap 2 and the watch body 1. The mating structure of the T-shaped slot and the T-shaped buckle can restrict the degree of freedom of the buckle 21 perpendicular to the sliding direction, preventing the buckle 21 from detaching radially from the slot 11. In an optional embodiment, the slot 11 can also adopt a dovetail groove structure, and the buckle 21 adopts a dovetail-shaped buckle that is compatible with the dovetail groove, further improving the anti-dislodgement performance of the buckle 21 and the slot 11; at the same time, the quick-release structure of this embodiment can adjust the size parameters according to different specifications of electronic products, adapt to different sizes of watch body 1 and watch strap 2, and has universality.

[0034] Please continue reading. Figure 1 and Figure 2 The body 1 has a sliding groove 12 inside, the central axis of which is perpendicular to the axis of the slot 11. One end of the sliding groove 12 extends through the inner wall of the slot 11, and the other end extends away from the slot 11 and closes. A snap-fit ​​member 31 is slidably fitted inside the sliding groove 12, one end of which can extend into the internal space of the slot 11. An elastic element is also fitted inside the sliding groove 12. In this embodiment, the elastic element is a spring 32, which is a cylindrical compression spring. One end of the spring 32 abuts against the inner wall of the closed end of the sliding groove 12 away from the slot 11. The free end of the spring 32 is fixedly connected to the end of the snap-fit ​​member 31 facing the spring 32. A locking groove 33 is provided on the side wall of the buckle 21 facing the opening of the sliding groove 12. When the buckle 21 slides along the slot 11 to the preset locking position, the lock... The fixed groove 33 and the sliding groove 12 are coaxially aligned and directly opposite each other. When the buckle 21 slides along the groove 11 toward the locking position, the end of the buckle 21 will abut against the end of the latching member 31 extending from the groove 11, pushing the latching member 31 to slide along the sliding groove 12 away from the groove 11. Simultaneously, the spring 32 is compressed to generate a pre-tightening force. When the buckle 21 slides to the locking position, the locking groove 33 and the sliding groove 12 are coaxially aligned. The spring 32 releases the pre-tightening force, pushing the latching member 31 to slide toward the groove 11, so that the end of the latching member 31 is embedded in the locking groove 33. This restricts the sliding freedom of the buckle 21 along the groove 11, thereby locking the watch strap 2 and the watch body 1. When disassembling, it is only necessary to slide the buckle 21 in the opposite direction to completely remove the latching member 31 from the locking groove 33 to release the limit, thus realizing the tool-free quick disassembly of the watch strap 2.

[0035] Please continue reading. Figure 2 In some embodiments of the present invention, the snap-fit ​​component 31 includes a slider 311 and a protrusion 312. The slider 311 is slidably assembled in the slide groove 12. The outer diameter of the slider 311 is adapted to the inner diameter of the slide groove 12. The single-sided fitting gap between the two is controlled at 0.2mm to ensure the coaxiality and stability of the slider 311. The end of the slider 311 facing the snap-fit ​​groove 11 is coaxially and fixedly connected to the protrusion 312. In this embodiment, the two are manufactured by an integral molding process to ensure the connection strength and coaxiality. The outer diameter of the protrusion 312 is smaller than the outer diameter of the slider 311. The end of the protrusion 312 away from the slider 311 extends into the snap-fit ​​groove 11 for insertion and engagement with the locking groove 33. The free end of the spring 32 is fixedly connected to the end of the slider 311 away from the protrusion 312. When the spring 32 pushes the slider 311 to slide along the slide groove 12, it can drive the protrusion 312 to move axially synchronously, so as to realize the action of the protrusion 312 being inserted into the locking groove 33 to complete the locking, or being withdrawn from the locking groove 33 to complete the unlocking.

[0036] Please continue reading. Figure 3 and Figure 4 The snap-fit ​​assembly 3 also includes a pin 34. The body 1 has a receiving groove 13, which is interconnected with the slide groove 12 and the snap-fit ​​groove 11. The pin 34 is fitted into the receiving groove 13, and the free end of the pin 34 extends into the snap-fit ​​groove 11. The slider 311 and the protrusion 312 are both cylindrical structures. The outer wall of the slider 311 has a continuous threaded guide groove 35, and the outer wall of the protrusion 312 has a threaded locking groove 36. The inner wall of the locking groove 33 has an external thread 37 that matches the threaded locking groove 36. The free end of the pin 34 always abuts against the inner wall of the threaded guide groove 35. It should be noted that, since the slider 311 needs to move axially and cooperate with the pin 34 to allow the slider 311 to rotate circumferentially while moving axially, those skilled in the art need to set the thread pitch of the threaded guide groove 35 and the threaded locking groove 36 to be relatively large to avoid the pin 34 from jamming with the threaded guide groove 35 or the threaded locking groove 36 from jamming with the external thread 37. When the spring 32 pushes the slider 311 to move axially along the slide groove 12, the fixed pin 34, through its contact with the threaded guide groove 35, restricts the slider 311 from moving linearly in the axial direction while simultaneously rotating in the circumferential direction, forming a spiral feed motion. This, in turn, drives the protrusion 312, which is fixed to the slider 311, to rotate in the spiral direction synchronously. This causes the threaded locking groove 36 on the outer wall of the protrusion 312 to form a stable threaded engagement connection with the external thread 37 on the inner wall of the locking groove 33. Based on the axial insertion locking, the threaded engagement forms a double limit in both the axial and circumferential directions, avoiding the shaking and movement problems that are prone to occur in pure insertion structures, and preventing the snap-fit ​​part 31 from being accidentally ejected due to vibration, thereby improving the long-term stability of the connection between the watch strap 2 and the watch body 1.

[0037] Please continue reading. Figure 3and Figure 4 The locking assembly 3 also includes a lever 38, which is fitted into the receiving groove 13. One end of the lever 38 is coaxially fixedly connected to the pin 34, and the free end of the lever 38 extends out of the receiving groove 13, forming an operating end that can be manually operated by the user. In the normally locked state, the pin 34 is in the initial position (located in the middle of the receiving groove 13), and its free end is stably abutting against the threaded guide groove 35, restricting the helical feed action of the slider 311 to be stably executed. When it is necessary to remove the watch strap 2, the user moves the free end of the lever 38. This causes the pin 34, which is fixed coaxially, to move in the direction of the locking groove 33. The positional change of the pin 34 applies a reverse driving force to the slider 311 through its cooperation with the threaded guide groove 35. This forces the slider 311 to move in the opposite axial direction along the groove 12 while simultaneously rotating in the opposite circumferential direction. This, in turn, causes the protrusion 312 to rotate in the opposite spiral direction, so that the threaded locking groove 36 of the protrusion 312 can be smoothly unscrewed from the external thread 37 on the inner wall of the locking groove 33, thus releasing the thread lock and enabling tool-free quick disassembly of the watch strap 2. The side wall of the receiving groove 13 is provided with a guide groove 131 for guiding the lever 38. The extension direction of the guide groove 131 is completely consistent with the set movement direction of the lever 38. The lever 38 passes through the guide groove 131. The two ends of the guide groove 131 are closed, which can limit the maximum movement stroke of the lever 38. The guide groove 131 can prevent the lever 38 from deviating, dislodging or misaligning during the tossing process, ensuring that the pin 34 and the threaded guide groove 35 always maintain a stable engagement relationship. At the same time, the closed guide groove 131 can limit the stroke of the lever 38 and avoid accidental unlocking caused by accidental contact.

[0038] Please continue reading. Figure 4The outer wall of the slider 311 is provided with a release groove 39. One end of the release groove 39 extends to the end face of the slider 311 facing the spring 32. The free end of the release groove 39 is connected to the threaded guide groove 35, and the release groove 39 is set parallel to the central axis of the slider 311. When the pin 34, in conjunction with the threaded guide groove 35, drives the slider 311 to complete the helical feed and causes the protrusion 312 to be fully screwed into the locking groove 33 to achieve threaded locking, the user can move the lever 38 to move the free end of the pin 34 along the release groove 39, and finally move it to the outer end of the slider 311, so that the pin 34 and the slider 311 are completely disengaged, releasing the pin 34 from the limiting constraint of the slider 311. This structure avoids the continuous contact and friction between the pin 34 and the slider 311 in the locked state, extending the service life of the structure, and avoiding the problem of accidentally triggering the unlocking by touching the lever 38 to drive the pin 34. At the same time, the release groove 39, which is set parallel to the axis of the slider 311, can ensure that the pin 34 slides smoothly without jamming and shorten the unlocking stroke. A locking element 310 is fixedly connected to the spring coil of spring 32. A through locking hole 341 is provided on the rod of pin 34. One end of the locking element 310 can be inserted into the locking hole 341. The locking element 310 has an "L"-shaped structure. One end of the locking element 310 is fixedly welded to the end spring coil of spring 32. The free end of the locking element 310 extends perpendicularly to the central axis of spring 32, matching the shape and size of the locking hole 341. When the lever 38 moves pin 34 to the locking position, the free end of the locking element 310 is inserted into the locking hole 341, achieving relative fixation between the spring coil of spring 32 and pin 34. During daily wear, when the protrusion 312 is subjected to vibration or impact and tends to rotate in the opposite direction and loosen, the locking component 310 will rotate with the slider 311 and drive the spring 32 to undergo torsional deformation, so that the spring 32 is transformed from an ordinary compression spring into a torsion spring and stores elastic potential energy. This elastic potential energy then drives the slider 311 and the protrusion 312 to rotate in the opposite direction and reset, so that the protrusion 312 is tightened back into the locking groove 33, thereby preventing the protrusion 312 from accidentally sliding out of the locking groove 33. This structure uses a single spring 32 to achieve both axial pushing and torsional anti-loosening functions, which simplifies the overall structure and can improve the impact resistance and anti-loosening performance of the locking structure.
