Description

Technical Field

[0001] This utility model belongs to the field of watch technology, specifically relating to a watch strap connector, a watch strap, and a smart wearable device. Background Technology

[0002] Smart wearable devices (such as watches) are accessories that people often wear in their daily lives. They consist of a watch strap and a watch face, which are connected by snap-fit ​​devices such as elastic pins.

[0003] Utility model patent application number 2023212632204 discloses a watch strap connector, a watch strap, and a smart wearable device. The watch strap connector of this utility model uses a guide protrusion and a limiting block to guide the sliding part along the sliding channel, preventing the sliding part from tilting upwards or shifting, thereby ensuring smooth extension and retraction.

[0004] Each watch strap connector requires two locking elements at both ends to ensure a secure connection with the watch case. However, in the aforementioned utility model, the locking elements of the watch strap connector include a sliding part and a bending part. The sliding part needs to be located within the through hole of the case, and the bending part is provided with a guide protrusion. That is, the locking elements at the left and right ends of the watch strap connector are only mirror-symmetrical, not centrally symmetrical. This makes the locking elements at both ends of the watch strap connector lack versatility (as per the appendix to the aforementioned utility model's specification). Figure 3 As shown in the figure, this means that the two snap-fit ​​parts cannot be processed by the same mold, which increases the difficulty and cost of processing. Utility Model Content

[0005] To address the issue of increased costs caused by the lack of interchangeability between the snap-fit ​​components at both ends of existing watch strap connectors, this utility model aims to provide a watch strap connector, a watch strap, and a smart wearable device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A watch strap connector includes a housing, a snap-fit ​​component, and a pressing component. The housing has first through holes at both ends. A snap-fit ​​component is slidably installed within each of the first through holes, with one end of the snap-fit ​​component passing through the first through hole. An elastic element is positioned between two snap-fit ​​components. The pressing component is connected to the snap-fit ​​components and controls their sliding. A guide groove is formed in the center of each snap-fit ​​component. Guide feet are located at both ends of the pressing component, respectively within the guide grooves of the two snap-fit ​​components. When the pressing component is pressed, the guide feet move the two snap-fit ​​components closer together, causing one end of the snap-fit ​​component to retract into the first through hole. When the pressing component is released, the elastic element pushes the two snap-fit ​​components away from each other, and the guide grooves of the two snap-fit ​​components push the guide feet back to their initial positions.

[0008] Optionally, one side of the guide groove has an inclined guide surface, and the inner side of the guide foot has a guide surface, with the guide surface of the guide groove and the guide surface of the guide foot fitting together.

[0009] Optionally, the snap-fit ​​component includes a limiting section and a sliding section. The outer dimensions of the limiting section are larger than the diameter of the first through hole. A guide groove is formed in the center of the limiting section, and the sliding section is located inside the first through hole.

[0010] Optionally, a positioning protrusion is provided at the end of the limiting section away from the sliding section, and the elastic element is a spring, with the two ends of the spring respectively fitted onto the positioning protrusions of the two snap-fit ​​parts.

[0011] Optionally, the bottom surface of the limiting section is provided with support feet.

[0012] Optionally, a mounting groove is provided in the center of the housing, and first through holes are provided on the side walls at both ends of the mounting groove. The snap-fit ​​component, elastic component and pressing component are all installed in the mounting groove.

[0013] Optionally, a cover is provided on the top surface of the housing, which covers the mounting groove, and a second through hole is provided in the center of the cover, through which the pressing component passes.

[0014] Optionally, two stepped holes are symmetrically provided on the cover, located on both sides of the second through hole. A locking hole is provided at the bottom of the mounting groove, and the locking element passes through the stepped hole and the snap-fit ​​element to connect with the locking hole.

[0015] This utility model also provides a watch strap, including the watch strap connector as described above.

[0016] This utility model also provides a smart wearable device, including the watch strap as described above.

[0017] The beneficial effects of this utility model are as follows:

[0018] The watch strap connector of this invention uses the guide pin of the pressing component to cooperate with the guide groove of the snap-fit ​​component to control the sliding of the snap-fit ​​component in the first through hole. This eliminates the bending part and guide part in the prior art, making the structure of the snap-fit ​​component universal. The snap-fit ​​components at the left and right ends can be directly interchanged, which means that the snap-fit ​​components used for the left and right ends of the watch strap connector can be formed by a single mold, reducing the processing difficulty of the product and greatly reducing production costs and efficiency. At the same time, this invention has a simple structure and is easy to operate. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] like Figures 1-4 The watch strap connector shown includes a housing 1, a snap-fit ​​component 4, and a pressing component 3. The housing 1 has first through holes 13 at both ends. A snap-fit ​​component 4 is slidably installed within the first through hole 13, with one end of the snap-fit ​​component 4 penetrating through the first through hole 13. An elastic element is provided between the two snap-fit ​​components 4. The pressing component 3 is connected to the snap-fit ​​component 4 and controls the sliding of the snap-fit ​​component 4. A guide groove 43 is provided in the center of the snap-fit ​​component 4. Guide feet 31 are provided at both ends of the pressing component 3, respectively located within the guide grooves 43 of the two snap-fit ​​components 4. When the pressing component 3 is pressed, the guide feet 31 cause the two snap-fit ​​components 4 to move closer together, thereby causing one end of the snap-fit ​​component 4 to retract into the first through hole 13. When the pressing component 3 is released, the elastic element pushes the two snap-fit ​​components 4 away from each other, causing one end of the snap-fit ​​component 4 to protrude beyond the first through hole 13, and the guide grooves 43 of the two snap-fit ​​components 4 push the guide feet 31 back to their initial positions. This invention achieves control over the sliding of the snap-fit ​​component 4 in the first through hole 13 by cooperating with the guide pin 31 of the pressing component 3 and the guide groove 41 of the snap-fit ​​component 4. This eliminates the bending part and guide part in the prior art, making the structure of the snap-fit ​​component 4 simpler and more versatile. The snap-fit ​​components 4 at the left and right ends can be directly interchanged, which in turn allows the snap-fit ​​components 4 at the left and right ends of the watch strap connector to be formed by a single mold, greatly reducing production costs.

[0037] Meanwhile, this utility model has a simple structure and is easy to operate. When it is necessary to replace the watch strap, pressing the pressing member 3 will disconnect the watch strap from the watch case. Similarly, when installing the watch strap, pressing the pressing member 3 will cause one end of the snap-fit ​​member 4 to retract into the first through hole 13, so that the case 1 can be placed between the two spring bars of the watch case. Then, releasing the pressing member 3 will cause the snap-fit ​​member 4 to pop out under the elastic action and snap into the spring bar, connecting the watch strap and the watch case together.

[0038] like Figures 7-11 As shown, one side of the guide groove 43 has an inclined guide surface, and the inner side of the guide pin 31 has a guide surface. The guide surfaces of the guide groove 43 and the guide pin 31 are in contact with each other. In use, the guide surface of the guide groove 43 is positioned on the side where the two snap-fit ​​pieces 4 are close to each other.

[0039] like Figures 8-11 As shown, the snap-fit ​​component 4 includes a limiting section 41 and a sliding section 42. The outer dimensions of the limiting section 41 are larger than the diameter of the first through hole 13, so that only the sliding section 42 can pass through the first through hole 13. The guide groove 43 is opened at the center of the limiting section 41, and the sliding section 42 is located inside the first through hole 13.

[0040] In this embodiment, a positioning protrusion 44 is provided at the end of the limiting segment 41 away from the sliding segment 42. The elastic element is a spring, and the two ends of the spring are respectively fitted onto the positioning protrusions 44 of the two snap-fit ​​pieces 4. Furthermore, both the positioning protrusion 44 and the sliding segment 42 are cylindrical, and the positioning protrusion 44 and the sliding segment 42 are coaxial, thereby ensuring that the snap-fit ​​pieces 4 at the left and right ends of the mounting groove 11 can still be interchanged.

[0041] It should be noted that the left and right directions described in this embodiment are based on... Figures 1-4 For reference only.

[0042] In this embodiment, a support foot 45 is provided on the bottom surface of the limiting section 41. The support foot 45 is used for height compensation and to reduce the contact area, thereby increasing the installation height of the sliding section 42 and ensuring that the sliding section 42 is as coaxial as possible with the first through hole 13, thus ensuring the sensitivity of the sliding section 42 within the first through hole 13. Furthermore, the support foot 45 should be provided while ensuring the versatility of the snap-fit ​​parts 4 at both ends of the mounting groove 11.

[0043] In other embodiments, support can also be provided by increasing the thickness of the limiting segment 41.

[0044] like Figures 1-4 As shown, a mounting groove 11 is provided in the center of the housing 1, and first through holes 13 are provided on the side walls at both ends of the mounting groove 11. The snap fastener 4, the elastic element and the pressing element 3 are all installed in the mounting groove 11.

[0045] like Figures 1-6As shown, a cover 2 is provided on the top surface of the housing 1. The cover 2 covers the mounting groove 11, and a second through hole 21 is provided in the center of the cover 2. The pressing member 3 passes through the second through hole 21.

[0046] Specifically, the top of the pressing member 3 passes through the second through hole 21, but the length of the two guide pins 31 of the pressing member 3 is greater than the length of the second through hole 21, so that the guide pins 31 limit the pressing member 3, so that only the top of the pressing member 3 can pass through the second through hole 21.

[0047] like Figure 5 and Figure 6 As shown, two stepped holes 22 are symmetrically opened on the cover 2. The two stepped holes 22 are located on both sides of the second through hole 21. A locking hole 12 is opened at the bottom of the mounting groove 11. The locking member 5 passes through the stepped hole 22 and the snap-fit ​​member 4 and is connected to the locking hole 12.

[0048] In this embodiment, the locking hole 12 is a threaded hole, and the locking component 5 is a countersunk bolt (e.g., Figure 12 As shown, the locking member 5 passes through the stepped hole 22 and the guide groove 43 and connects to the locking hole 12. The nut of the countersunk bolt is recessed into the stepped hole 22.

[0049] In this embodiment, the thickness of the guide pin 31 is greater than the gap between the guide groove 43 and the cover 2, so that the guide pin 31 is always partially located within the guide groove 43. Furthermore, the guide pin 31 is always located between the locking member 5 and the guide surface of the guide groove 43, and the guide pin 31 does not contact the locking member 5.

[0050] This utility model also provides a watch strap, including the watch strap connector as described above. The watch strap of this embodiment also has the above-mentioned effects, which will not be repeated here.

[0051] This utility model also provides a watch strap as described above. The watch strap of this embodiment also has the above-mentioned effects, which will not be described in detail here.

[0052] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
