Description
Technical Field
[0001] This utility model relates to the technical field of watch protection devices, and in particular to a watch protective case and watch strap. Background Technology
[0002] With the development of electronic products, many traditional electronic products have begun to add new functions. Watches, which used to be used only for telling time, can now connect to the internet and have various functions, such as displaying incoming calls, monitoring heart rate, and viewing news. Watches are worn on the wrist, and in daily activities, they are easily scratched or bumped, leading to dirt, scratches, or even direct damage. To protect watches, they are usually encased in a protective case. Existing watch cases are generally made of one-piece injection-molded soft rubber. Soft rubber deforms upon impact, directly compressing the internal watch case. Furthermore, over time, it oxidizes and yellows, resulting in poor impact protection and aesthetics.

[0021] Reference Figure 1 and Figure 2 This application provides a watch protective case 10, including a soft rubber case 100 and a metal case 200, both of which are hollow structures 11 with front and back openings. The metal case 200 is housed within the soft rubber case 100, and the back opening of the metal case 200 is configured to allow most of the watch body 20 to pass through and extend into it. The inner side of the front of the soft rubber case 100 has a snap-fit structure 110 for snapping and securing the front of the metal case 200. The back of the soft rubber case 100 extends inward to form an annular first overlapping step 120, located outside the back opening of the metal case 200, for supporting the watch body 20. It should be understood that the aforementioned inward extension refers to radial extension along the hollow structure 11; here, the front and back of the soft rubber case 100 and the front and back of the metal case 200 are opposite each other, and are not necessarily related to the front and back of the watch body 20. Specifically, in this embodiment, the soft rubber case 100 is used to fasten the back of the watch body 20, and the metal case 200 is used to fasten the front of the watch body 20. The watch body 20 can be squeezed into the hollow structure 11 through one side opening of the soft rubber case 100 so that the watch protective case 10 can be installed and fixed on the outside of the watch body 20.
[0022] The watch case 10 provided in this application is assembled from a soft rubber case 100 and a metal case 200, combining the metallic feel with the cushioning and protective function of flexible materials. Specifically, compared to previous pure metal watch cases (which have both a front cover and a back cover), the watch case 10 of this application can be protected from impacts by the soft rubber case 100, increasing the overall lifespan of the watch case 10; while compared to a pure soft rubber case, the front of the metal case 200 enhances the overall metallic feel, achieving both benefits.
[0023] Optionally, combined Figure 2-4 In one embodiment, the snap-fit structure 110 includes a guide wall 111. The guide wall 111 extends inward and forward or in an arc shape from the inner side of the front of the soft plastic shell 100, forming a guide slope or guide arc surface (not shown). The guide slope is simultaneously inclined to the axial and radial extension of the hollow structure 11. When the front edge of the metal shell 200 is inserted, it abuts against the guide slope and causes it to elastically deform until it is snapped into the inner side of the guide wall 111 and fixed. It is understood that the soft plastic shell 100 can undergo elastic deformation, and the size of its front opening can be changed by external force. After the metal shell 200 is inserted into the soft plastic shell 100, it will squeeze the guide wall 111 of the soft plastic shell 100. The guide wall 111 elastically abuts against the outer side wall of the metal shell 200 to achieve an interference fit between the soft plastic shell 100 and the metal shell 200. The metal shell 200, as the inner lining of the soft plastic shell 100, plays a role in stabilizing and fixing the soft plastic shell 100. It should be understood that in other embodiments, the guide wall 111 is not required. Any means that can achieve the snap-fit connection between the soft plastic shell 100 and the metal shell 200 should be protected.
[0024] Optionally, combined Figure 2 and Figure 4 In one embodiment, the guide walls 111 are continuously or intermittently distributed on the inner circumferential side of the front of the soft plastic case 100, that is, the guide walls 111 are symmetrically distributed on the inner circumferential side of the front of the soft plastic case 100 to enhance the assembly stability of the entire watch protective case 10. Figure 2 The illustration shows the spacing distribution, with guide walls 111 formed on the front and rear sides or left and right sides of the soft rubber shell 100, arranged symmetrically. Of course, in other embodiments, the guide walls 111 may also be asymmetrically distributed.
[0025] Optionally, refer to Figure 4 The guide wall 111 and the outer wall of the metal shell 200 are each provided with a locking block 130 and a locking groove 210, respectively. The locking block 130 is aligned and engaged with the locking groove 210. Furthermore, the locking block 130 and the locking groove 210 are engaged along the axial direction of the hollow structure 11 to further enhance the assembly stability of the entire watch protective case 10. Of course, in other embodiments, the presence or absence of the locking block 130 and the locking groove 210 is not limited; the engagement direction of the locking block 130 and the locking groove 210 is also not limited.
[0026] Optionally, combined Figure 2 and Figure 4In one embodiment, a connecting protrusion 220 extends outward from the back of the metal casing 200. The connecting protrusion 220 extends outward at an angle to the axial direction of the hollow structure 11. The soft rubber casing 100 has a corresponding connecting groove 140 on the inner sidewall of its back. The connecting protrusion 220 is aligned and engaged with the connecting groove 140 to further enhance the assembly stability of the entire watch protective case 10. Of course, in other embodiments, the connecting protrusion 220 and the connecting groove 140 may not be provided.
[0027] Optionally, combined Figure 4 , Figure 5 and Figure 6 In one embodiment, the inner sidewall of the soft rubber shell 100 extends inward to form an annular second overlapping step 150, and the open end face of the back of the metal shell 200 abuts against the step surface of the second overlapping step 150; the inner sidewall of the soft rubber shell 100 and the inner sidewall of the metal shell 200 are smoothly connected. This smooth connection allows the watch body 20 to simultaneously and tightly fit the inner sidewalls of both the soft rubber shell 100 and the metal shell 200, reducing the gap between the watch body 20 and the watch protective case 10 and improving assembly compactness.
[0028] Optionally, combined Figure 1 and Figure 2 In one embodiment, a connecting portion 230 extends axially along the hollow structure 11 from one side of the back of the metal casing 200. The connecting portion 230 is attached to the inner side of the soft rubber casing 100. The connecting portion 230 has a first functional hole 231, and the soft rubber casing 100 has a second functional hole 160. The first functional hole 231 and the second functional hole 160 are radially opposite each other along the hollow structure 11. The first functional hole 231 and the second functional hole 160 allow the function buttons 21 of the watch body 20 to pass through sequentially and protrude to the outside, thereby further enhancing the assembly stability of the entire watch protective case 10. It should be noted that in other embodiments, only one of the first functional hole 231 and the second functional hole 160 may be provided for the function buttons 21 to pass through and protrude.
[0029] Optionally, combined Figure 2 and Figure 4 In one embodiment, the watch case 10 includes a cushioning pad 300, which is attached to the inner wall of the metal case 200 to prevent direct contact between the metal case 200 and the watch body 20. Both are made of hard materials, preventing the outer wall of the watch body 20 from being scratched or bumped by the metal case 200, further enhancing the protective performance of the entire watch case 10 for the watch body 20. The cushioning pad 300 is made of cushioning materials such as soft rubber, foam, etc. Of course, in other embodiments, the cushioning pad 300 may not be required.
[0030] Secondly, refer to Figure 1This application also provides a watch strap 1, including a watch protective case 10 and a strap body 30. Two strap bodies 30 are respectively connected to opposite sides of the soft rubber case 100. Here, the strap body 30 can be rotatably connected to the watch protective case 10 to better conform to the curvature of the wrist and improve wearing comfort; the strap body 30 can also be fixedly connected to the watch protective case 10, and the strap body 30 and the soft rubber case 100 are integrally formed. The watch strap 1 of this application serves both to wear the watch body 20 and to protect the watch body 20, and has strong practicality.
[0031] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
