Description

Technical Field

[0001] This utility model relates to the field of watch technology, and further to a press-connection structure and a button-type smartwatch. Background Technology

[0002] With the continuous advancement of wearable technology, smartwatches have evolved into multifunctional devices integrating calling, Bluetooth communication, GPS positioning, touch display, and photography. However, most smartwatches on the market currently adopt a design where the watch face and strap are fixedly connected. This structure has obvious drawbacks in actual use: when answering a call, users must remove the watch from their wrist or untie the strap before placing the watch face to their ear to make the call. This is not only cumbersome and affects efficiency, but the frequent disassembly and reassembly will also accelerate the wear and tear on the strap and shorten the lifespan of the device.

[0003] In the existing technology, in order to solve the problem of inconvenience during calls, some manufacturers have tried to adopt a detachable watch face design. However, these solutions usually rely on complex buckle structures or require external tools to complete the disassembly and assembly. The operation steps are cumbersome and the user experience is poor. At the same time, although some products support quick separation of the watch face and the base, there is no stable and reliable connection mechanism between the separated watch face and the base. This makes it easy for the watch face to fall off accidentally during normal use, affecting the reliability of the device and the user's sense of security.

[0004] Therefore, there is an urgent need to design a simple, easy-to-operate, and highly reliable connection scheme between the dial and the base to solve the problems mentioned above. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to provide a press-connection structure and a button-type smartwatch, which can solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a press-fit connection structure, comprising:

[0007] The device includes a side plate, a transmission component, a guide component, a resettable pressing component, and a resettable connecting component. The side plate is connected to the external dial. The transmission component is rotatably mounted on the side plate and has a force-receiving part and a force-transmitting part. The force-receiving part is in corresponding contact with the resettable pressing component, and the force-transmitting part is in corresponding contact with the resettable connecting component. The guide component is parallel to the resettable connecting component and extends in opposite directions.

[0008] The movement trajectory of the resettable pressing member is perpendicular to the movement trajectory of the resettable connecting member;

[0009] When the resettable pressing member is pressed, the resettable pressing member drives the force receiving part to rotate the transmission part, and the force transmitting part simultaneously pushes the resettable connecting member to move along a trajectory perpendicular to the pressing direction, so that the resettable connecting member is disengaged from the external chassis to be connected.

[0010] After the resettable pressing component is released, the resettable pressing component and the resettable connecting component can automatically reset, and the resettable connecting component can re-clamp onto the external chassis to be connected.

[0011] In some embodiments, the resettable connector is provided with a first extension, and a first elastic member is sleeved on the first extension. The first extension and the first elastic member are used to provide elastic force for the resettable connector.

[0012] The resettable pressing member is provided with a second extension member, and a second elastic member is correspondingly sleeved on the second extension member. The second extension member and the second elastic member are used to provide elastic force for the resettable connector.

[0013] By setting a first elastic element and a second elastic element, the resettable connector and the resettable pressing element can automatically spring back to their initial positions after the pressing operation is completed, without the need for manual reset. At the same time, after the pressing element resets, the first elastic element can automatically drive the resettable connector back to its original position and re-lock it, without the need for manual reset. This not only ensures the stability of the connection between the dial and the base, but also further simplifies the operation process and improves the automation and convenience of disassembly and assembly.

[0014] In some embodiments, a first limiting member is provided on the side plate, and a second limiting member corresponding to the first limiting member is provided on the resettable pressing member.

[0015] By setting the first and second limiting components to work together, the maximum reset stroke of the resettable pressing component can be precisely limited. This ensures that the resettable pressing component only needs to be pressed to the preset position to disengage the resettable connector from the structure to be connected, thereby effectively improving the accuracy of operation and the durability of the components, and extending the overall service life of the pressing connection assembly.

[0016] In some embodiments, a first snap-fit ​​hook is provided at the end of the resettable connector away from the transmission member. The first snap-fit ​​hook engages with an external chassis to be connected, and the contact surface between the first snap-fit ​​hook and the external chassis to be connected is parallel to the moving direction of the resettable connector.

[0017] By setting up a hook-shaped engagement structure for the locking hooks, a stable mechanical lock is formed, which effectively prevents the watch face from accidentally detaching from the base during daily wear, sports, and other scenarios, ensuring the firmness of the connection. At the same time, the pressing contact surface is parallel to the moving direction of the resettable connector, which allows the two locking hooks to be quickly separated, taking into account both connection stability and ease of disassembly and assembly, and balancing the product's wearing reliability and usage flexibility.

[0018] According to another aspect of the present invention, the present invention further provides a button-type smartwatch, comprising:

[0019] A base to which a watch strap is attached, and a connecting part is provided on one side of the base;

[0020] The dial has a docking part on one side corresponding to the connecting part. The docking part is detachably connected to the base by a press-connecting structure as described in any of the above embodiments. The resettable connector is correspondingly and movably engaged with the connecting part. When the resettable press is pressed to the expected position, the resettable connector disengages from the connecting part.

[0021] In some embodiments, the docking portion is provided with a first reset groove and a pressing groove, the first reset groove and the pressing groove are connected, and the direction in which the first reset groove extends is perpendicular to the direction in which the resettable pressing member presses.

[0022] The resettable connector is correspondingly embedded in the first reset groove, and the resettable pressing member is adapted to move within the pressing groove.

[0023] A first reset groove is provided to precisely guide the movement of the resettable connector, ensuring its displacement along a fixed trajectory. A second reset groove provides guidance and limitation for the resettable press, guaranteeing the accuracy of the press's stroke and preventing displacement due to accidental activation or external pressure. This effectively prevents the resettable connector from being accidentally triggered and disengaged, significantly improving the product's anti-accidental activation performance and safety.

[0024] In some embodiments, a support block is provided in the pressing groove, the support block has a guide groove corresponding to the guide member, and the support block has a second reset groove, the resettable pressing member is correspondingly embedded in the second reset groove.

[0025] In some embodiments, the connecting portion is provided with a second snap hook corresponding to the resettable connector;

[0026] The connecting part has a connecting groove, and the end of the second snap hook away from the resettable connector is correspondingly snapped into the connecting groove.

[0027] In some embodiments, a sliding groove is provided on the connecting part, and the sliding groove is provided on the connecting part at a position corresponding to and close to the second snap hook.

[0028] The opening of the sliding groove provides ample space for the first snap hook of the resettable connector to move and deform, reducing the frictional resistance of the snap hook during the snap-in and snap-out process, making the disassembly and assembly operations smoother and less strenuous; at the same time, it can avoid wear caused by hard friction on the snap hook, extend the service life of the snap-in structure, and further improve the smoothness of the disassembly and assembly operations.

[0029] In some embodiments, a pad is movably disposed on the chassis, one side of the pad being snap-fitted to the side of the chassis away from the connecting part, and the other side of the pad being screwed to the side of the chassis near the connecting part.

[0030] Compared with the prior art, the button-type smartwatch provided by this utility model has the following beneficial effects:

[0031] 1. The button-type smartwatch provided by this utility model, by setting a press connection component consisting of a resettable press part and a resettable connector, realizes quick and convenient one-click disassembly and connection of the watch face relative to the base. It effectively solves the problems of inconvenience in answering calls and easy damage to the watch face due to the fixed connection between the watch face and the watch strap in the prior art. It significantly improves the flexibility of device use and significantly improves the convenience and experience of users when using smartwatches.

[0032] 2. The button-type smartwatch provided by this utility model sets the movement trajectory of the resettable pressing component and the movement trajectory of the resettable connecting component to be perpendicular to each other. By utilizing the perpendicular movement trajectory to adapt to the narrow space layout inside the smartwatch, the direction of force is converted. Thus, the force-bearing part of the transmission component receives the pressing force of the resettable pressing component, and the force-transmitting part transmits the force to the resettable connecting component, making the pressing operation more effortless and the transmission smoother. At the same time, the side plate provides stable rotation support for the transmission component, ensuring the compact structure and transmission reliability of the pressing connection component, and adapting to the miniaturized product form of the smartwatch.

[0033] 3. The button-type smartwatch provided by this utility model, by setting a guide component, forms a double guide structure with the cooperation of the guide groove, which effectively restricts the displacement direction of the resettable connector, prevents it from shifting or getting stuck during movement, ensures the accuracy of the locking and unlocking action, and avoids connection failure caused by component misalignment, thereby further improving the structural stability and reliability of the press connection component.

In this document, "one" not only means "only one," but can also mean "more than one."

[0045] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0046] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] In one embodiment, refer to the appendix to the specification. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The present invention provides a press-fit connection structure, including a side plate 33, a transmission component 32, a guide component 36, a resettable press component 31, and a resettable connector 30. The side plate 33 is connected to the outer dial 20. The transmission component 32 is rotatably mounted on the side plate 33 and has a force-receiving part 321 and a force-transmitting part 322. The force-receiving part 321 is in corresponding contact with the resettable press component 31, and the force-transmitting part 322 is in corresponding contact with the resettable connector 30. The guide component 36 is parallel to the resettable connector 30 and extends in opposite directions. The movement trajectory of the pressing member 31 is perpendicular to the movement trajectory of the resettable connector 30. When the resettable pressing member 31 is pressed, the resettable pressing member 31 drives the force receiving part 321 to drive the transmission part 32 to rotate. The force transmission part 322 simultaneously pushes the resettable connector 30 to move along a trajectory perpendicular to the pressing direction, so that the resettable connector 30 is disengaged from the external chassis to be connected. After the resettable pressing member 31 is released, the resettable pressing member 31 and the resettable connector 30 can automatically reset, and the resettable connector 30 re-engages with the external chassis to be connected.

[0048] Specifically, the press-fit connection assembly mainly includes a press member 31 and a resettable connector 30. A portion of the press member 31 is exposed on the surface of the dial 20 for easy operation with the user's fingers. The main body of the press member 31 is located within the mating portion. The side plate 33 is a thin metal sheet, fixed to the dial 20 by a rotating screw 34. The transmission member 32 is rotatably mounted on the side plate 33 via the rotating screw 34 that fixes the side plate 33. One end of the transmission member 32 has a force-receiving part 321, which is a right-angled concave platform that contacts the right-angled part at the bottom of the press member 31; the other end has a force-transmitting part 322, which is a flat push edge that contacts the side wall of the resettable connector 30. When the user presses the pressing part 31, the pressing force is transmitted to the transmission part 32 through the force receiving part 321, causing it to rotate around the shaft pin. Then, through the force transmission part 322, it pushes the resettable connector 30 away from the pressing part 31. As the pressing continues, it eventually disengages from the slot of the chassis, completing the unlocking action. In addition, the guide part 36 is arranged parallel to the first extension part and is always constrained during the movement, effectively preventing the resettable connector 30 from deflecting or shaking during horizontal movement, ensuring that the locking action is accurate and reliable. This makes the movement trajectory of the resettable connector 30 more stable, reduces frictional resistance during the movement, and extends the service life of the product.

[0049] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, a first extension is provided on the resettable connector 30, and a first elastic member 35 is sleeved on the first extension. The first extension and the first elastic member 35 are used to provide elastic force for the resettable connector 30. A second extension is provided on the resettable pressing member 31, and a second elastic member 37 is correspondingly sleeved on the second extension. The second extension and the second elastic member 37 are used to provide elastic force for the resettable connector 30.

[0050] Specifically, the resettable connector 30 is provided with a first extension, and a first elastic element 35 is sleeved on the first extension. The first elastic element 35 is a compression spring. The first extension and the first elastic element 35 are embedded in the first reset groove 22. When the resettable connector 30 is pushed away from the chassis by the transmission member 32, the first elastic element 35 is in a compressed state. Once the user releases the pressing member 31, the first elastic element 35 releases its elastic force, pushing the resettable connector 30 back to the initial snap-fit ​​position, preparing for the next installation. The bottom of the pressing member 31 is provided with a second extension, and a second elastic element 37 is sleeved on the second extension. The second elastic element 37 is also a compression spring. The second extension and the second elastic element 37 are embedded in the second reset groove 24. When the user presses the pressing member 31, the second elastic element 37 is compressed. After releasing, the second elastic element 37 pushes the pressing member 31 to automatically reset to the initial position, ensuring that the system returns to standby state after each operation and avoiding the impact of the pressing member 31 jamming on subsequent use. This reset structure makes the operation smoother, allowing users to proceed with the next operation without waiting.

[0051] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, a first limiting member 39 is provided on the side plate 33, and a second limiting member 311 corresponding to the first limiting member 39 is provided on the resettable pressing member 31.

[0052] Specifically, the side plate 33 is provided with a first limiting member 39, and the pressing member 31 is provided with a corresponding second limiting member 311311. When the pressing member 31 is reset to the predetermined position, the second limiting member 311311 contacts the first limiting member 39, preventing the pressing member 31 from continuing to rise, thereby preventing excessive reset that could cause the pressing member 31 to detach.

[0053] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, a first snap hook 38 is provided at one end of the resettable connector 30 away from the transmission member 32. The first snap hook 38 is snapped into the corresponding external chassis to be connected, and the contact surface between the first snap hook 38 and the external chassis to be connected is parallel to the moving direction of the resettable connector 30.

[0054] Specifically, the contact surface of the first snap hook 38 with the external chassis to be connected is parallel to the moving direction of the resettable connector 30, so that the force direction during unlocking is completely consistent with the normal direction of the contact surface. When the pressing component drives the resettable connector 30 to move along the preset trajectory, the driving force can be directly applied to the snap contact surface without overcoming the lateral component force, making it smoother and more labor-saving to use. At the same time, it further enhances the snap tightness and avoids the snap hook from accidentally shifting or coming off due to external impact.

[0055] According to another aspect of this utility model, reference is made to the appended specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, the present invention further provides a button-type smartwatch, including a base 10 and a dial 20. The base 10 is connected to a watch strap, and a connecting part is provided on one side of the base 10. The dial 20 is provided with a docking part on the side corresponding to the connecting part. The docking part is detachably connected to the base 10 by a press-connecting structure as described in any of the above embodiments. The resettable connector 30 is corresponding to the movable snap-fit ​​connecting part. The resettable connector 30 is disengaged from the connecting part when the resettable press 31 is pressed to the expected position.

[0056] Specifically, a button-type smartwatch mainly includes a base 10 and a dial 20. The base 10 is usually made of engineering plastic or metal with strength and toughness, and its two ends are connected to a watch strap for wearing. On one side of the upper surface of the base 10, there is an upwardly protruding connecting part. The dial 20 integrates the core functional modules of the smartwatch, such as display, processing, sensing, and communication. On the back of the dial 20, corresponding to the position of the connecting part of the base 10, there is an inwardly recessed mating part. The dial 20 is detachably mechanically connected to the connecting part of the base 10 through the press-connecting structure on its mating part.

[0057] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiment, the docking part is provided with a first reset groove 22 and a pressing groove 21. The first reset groove 22 and the pressing groove 21 are connected and the direction of extension of the first reset groove 22 is perpendicular to the pressing direction of the resettable pressing member 31.

[0058] The resettable connector 30 is correspondingly embedded in the first reset groove 22, and the resettable pressing member 31 is adapted to move within the pressing groove 21.

[0059] Specifically, the docking part is provided with a first reset groove 22 and a pressing groove 21, which are connected to each other. The first reset groove 22 is used to accommodate the horizontal movement of the resettable connector 30; the pressing groove 21 is used to accommodate the vertical movement of the pressing member 31.

[0060] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 A support block 23 is provided in the pressing groove 21. A guide groove 25 corresponding to the guide member 36 is provided on the support block 23. A second reset groove 24 is provided on the support block 23. The resettable pressing member 31 is correspondingly embedded in the second reset groove 24.

[0061] Specifically, a guide groove 25 matching the guide member 36 is provided on the support block 23 inside the press groove 21 in the dial 20. The size of the guide groove 25 is slightly larger than that of the guide member 36 to provide an appropriate sliding clearance. The guide member 36 is slidably embedded in the guide groove 25. The extension direction of the second reset groove 24 is consistent with the pressing direction of the resettable press member 31. The second extension member and the second elastic member 37 are embedded in the second reset groove 24. When the user presses the resettable press member 31, the second elastic member 37 is compressed into the second reset groove 24, which effectively prevents the second extension member and the second elastic member 37 from deflecting or shaking when moving horizontally.

[0062] The resettable connector 30 has a first locking hook 38 at the end away from the transmission component 32. The first locking hook 38 is an outwardly curved L-shaped structure. The connecting part is correspondingly provided with a second locking hook 11, which is an inwardly curved L-shaped structure. When the dial 20 is inserted into the base 10, the first locking hook 38 and the second locking hook 11 engage with each other to form a mechanical lock, so as to ensure that the connection strength between the dial 20 and the base 10 is sufficient to withstand the pulling force during daily wear and use, and effectively prevent the dial 20 from falling off due to accidental vibration or pulling during use.

[0063] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiments, a second snap hook 11 corresponding to the resettable connector 30 is provided on the connecting part;

[0064] A connecting groove 13 is provided on the connecting part, and the end of the second snap hook 11 that is away from the resettable connector 30 is correspondingly snapped into the connecting groove 13.

[0065] Specifically, a connecting groove 13 is also provided on the connecting part. The connecting groove 13 is preferably a rectangular groove, located on the connecting part near the second snap hook 11. The end of the second snap hook 11 away from the first snap hook 38 is embedded in the connecting groove 13. This structure not only enhances the support strength of the second snap hook 11 and prevents it from deforming or breaking during long-term use, but also further improves the overall stability and pull-out resistance of the snap-fit ​​part, further ensuring the reliability of the product in various usage scenarios.

[0066] In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiment, a sliding groove 12 is provided on the connecting part, and the sliding groove 12 is provided on the connecting part at a position corresponding to the second snap hook 11.

[0067] Specifically, a sliding groove 12 is provided on the connecting part near the second snap hook 11. The sliding groove 12 is a rectangular groove. During the insertion of the dial 20, the first snap hook 38 slides in along the sliding groove 12, guiding it to smoothly engage with the second snap hook 11, reducing assembly resistance and improving installation smoothness. The structural design of the sliding groove 12 makes the installation of the dial 20 simpler and faster, thereby improving the user experience of the product.

[0068] 7. In one embodiment, refer to the appendix to the specification. Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on the above embodiment, a pad 40 is movably provided on the chassis. One side of the pad 40 is snap-fitted to the side of the chassis away from the connecting part, and the other side of the pad 40 is screwed to the side of the chassis near the connecting part.

[0069] Specifically, the base 10 is movably provided with a pad 40, one side of which is connected to the inner wall of the base 10 away from the connecting part by a snap-fit ​​structure, and the other side is fixed to the area of ​​the base 10 near the connecting part by two screws. The upper surface of the pad 40 contacts the bottom of the dial 20, providing additional support and cushioning. This ensures the rigidity of the overall structure of the base 10, facilitates the assembly and maintenance of internal components, absorbs some external impacts, improves product durability, and extends the product's service life.

[0070] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
