[0001] This utility model relates to the field of wearable device connection technology, and in particular to a watch protective case and wearable device. Background Technology

[0002] To enhance the security of smartwatches, protective cases are typically used to encase and assemble them, providing improved waterproofing, dustproofing, and impact resistance. In recent years, with the widespread use of smartphones, smartwatches, and other electronic devices, the protective cases installed on these devices have become increasingly diverse. Currently, the most common type is the soft rubber protective case, which is made using a single injection molding process. Hard protective cases generally employ a semi-enclosed or modular assembly structure. For modular structures, the various parts of the protective case are fastened together using a snap-fit ​​method. However, during the installation and installation process, the snap-fit ​​structure between the different parts of the protective case is relatively fragile and prone to breakage and damage. Utility Model Content

[0003] The present invention provides a watch protective case to solve the technical problem that the fastening structure between the various parts of the protective case is relatively weak and easily breaks and is damaged during the process of users attaching the protective case.

[0004] This utility model discloses a watch protective case, comprising:

[0006] The lower shell is a second hollow structure with an opening at least one end. The second hollow structure has a third end and a fourth end opposite to each other. The third end is an open window and is connected to the second end. The first hollow structure is in communication with the second hollow structure. The upper shell and the lower shell enclose each other to form a mounting cavity. The mounting cavity fixes the meter head between the first end and the fourth end.

[0007] The second end and the third end are provided with a hook protruding along the depth direction of the mounting cavity, and the other end is provided with a hanging platform. The hook is provided with longitudinally extending reinforcing ribs on opposite sides. When the third end is connected to the second end, the hook is hooked to the hanging platform, and the hanging platform is located between the two reinforcing ribs to complete the fastening between the upper shell and the lower shell.

[0008] In one embodiment, the hook is connected to the third end, the reinforcing rib extends from the end face of the third end to the end of the hook, the lower shell, the two reinforcing ribs, and the hook together form a first groove, and the hanging platform is located within the first groove;

[0009] Alternatively, the hook is connected to the second end, the reinforcing rib extends from the end face of the second end to the end of the hook, the upper shell, the two reinforcing ribs and the hook form a second groove, and the hanging platform is located within the second groove.

[0010] In one embodiment, the thickness of the reinforcing rib is not greater than the thickness of the hook end in the radial direction of the mounting cavity.

[0011] In one embodiment, the mounting platform has limiting notches on both sides, which extend along the depth direction of the mounting cavity to form an opening. When the upper shell and the lower shell are fastened together, the reinforcing rib enters the limiting notch through the opening.

[0012] In one embodiment, the protrusion height of the mounting platform along the radial direction of the mounting cavity is not greater than the depth of the limiting notch, so that the hook and the reinforcing rib do not protrude from the limiting notch; and / or, the side of the hook away from the mounting platform smoothly contacts the inner wall of the mounting cavity.

[0013] In one embodiment, at least one of the end of the hook and the hanging platform is provided with a guide surface, the guide surface extending inclined in the hooking direction; when the upper shell and the lower shell are aligned and fastened, the end of the hook and the hanging platform move relative to each other along the guide surface until the hook and the hanging platform are fully engaged.

[0014] In one embodiment, one of the second end and the three ends is provided with a positioning post, and the other is provided with a positioning hole. The positioning post extends along the depth direction of the mounting cavity. When the upper shell and the lower shell are aligned and fastened, the positioning post is aligned and engaged in the positioning hole. The positioning post and the hook are spaced apart along the side periphery of the mounting cavity.

[0015] In one embodiment, the first end extends radially inward along the mounting cavity to form a first annular step, the two step surfaces of the first annular step being connected by curved surfaces, and the first annular step being used to cover the upper surface edge of the meter head; and / or, the fourth end extends radially inward along the mounting cavity to form a second annular step, the two step surfaces of the second annular step being connected by curved surfaces, and the second annular step being used to cover the lower surface edge of the meter head.

[0016] In one embodiment, the watch case includes a cushioning pad that is attached to the inner sidewall of the lower case and / or the upper case.

[0017] In one embodiment, when the upper shell is fastened to the lower shell, the outer wall surfaces of the upper shell and the lower shell are smoothly connected.

[0018] In one embodiment, the third end is connected to the second end to form a functional hole. The functional hole is located on the side periphery of the mounting cavity and communicates with the mounting cavity and the outside. The functional hole allows the function key of the meter to extend out from the mounting cavity.

[0019] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0020] This utility model provides a watch protective case, including an upper case and a lower case, which together form a mounting cavity for mounting and fixing the watch head. A second end and a third end are respectively provided with a hook and a mounting platform. The hook has longitudinally extending reinforcing ribs on opposite sides. When the third end is connected to the second end, the hook is engaged with the mounting platform, which is confined between the two reinforcing ribs to complete the connection between the upper and lower cases. On the one hand, because the hook has reinforcing ribs on both sides, its strength is enhanced, making it less prone to breakage during the connection process and improving the overall lifespan of the watch protective case. On the other hand, because the hook is engaged with the mounting platform, and the platform is confined between the two reinforcing ribs, the relative movement between the hook and the platform is restricted, further enhancing the connection between the upper and lower cases and improving the assembly stability of the entire watch protective case.

[0033] Reference Figure 1 and Figure 2This application provides a novel watch protective case 10, which is fitted onto the outside of the watch head to provide waterproof, dustproof, and impact-resistant protection. The watch protective case 10 includes an upper shell 100 and a lower shell 200, which together form a mounting cavity 11 for mounting and securing the watch head. Specifically, the upper shell 100 is a first hollow structure 101 with openings at both ends. The first hollow structure 101 has a first end 110 and a second end 120 disposed opposite each other along the depth direction of the mounting cavity 11. The first end 110 has a light-transmitting window 111, which can be an opening or a transparent protective film, allowing the user to view the watch head's display screen through the window 111. The lower shell 200 is a second hollow structure 201 with at least one open end. The second hollow structure 201 has a third end 210 and a fourth end 220 opposite to each other along the depth direction of the mounting cavity 11. The third end 210 is an open window and is connected to the second end 120. The first hollow structure 101 is connected to the second hollow structure 201 so that the upper shell 100 and the lower shell 200 enclose the mounting cavity 11, and the mounting cavity 11 fixes the meter between the first end 110 and the fourth end 220.

[0034] Reference Figure 2-4 The second end 120 and the third end 210 each have a hook 230 protruding along the depth direction of the mounting cavity 11, and a mounting platform 130. Longitudinal reinforcing ribs 240 extend from opposite sides of the hook 230, where the longitudinal extension direction refers to the length extension direction of the hook 230, i.e., the depth direction of the mounting cavity 11. When the second end 120 and the third end 210 are connected, the hook 230 is hooked onto the mounting platform 130, and the mounting platform 130 is positioned between the two reinforcing ribs 240 to complete the connection between the upper shell 100 and the lower shell 200. It should be noted that the hook 230 and the mounting platform 130 can be interlocked, and the same connection effect can be achieved by interchangeing their positions. That is, the second end 120 has a mounting platform 130, and the third end 210 has a hook 230; or the second end 120 has a hook 230, and the third end 210 has a mounting platform 130.

[0035] The watch protective case provided in this application, on the one hand, has reinforcing ribs 240 on both sides of the hook 230 to enhance its strength, making the hook 230 less prone to breakage or damage during the fastening process between the upper case 100 and the lower case 200, thus improving the overall service life of the watch protective case 10. On the other hand, since the hook 230 is attached to the mounting base 130, and the mounting base 130 is confined between the two reinforcing ribs 240, the relative movement between the hook 230 and the mounting base 130 is restricted, further enhancing the fastening performance between the upper case 100 and the lower case 200 and improving the assembly stability of the entire watch protective case 10.

[0036] Preferably, in conjunction with reference Figure 3 and Figure 4 In one embodiment, the hook 230 is connected to the third end 210, and the reinforcing rib 240 extends from the end face of the third end 210 to the end of the hook 230. The lower shell 200, the two reinforcing ribs 240, and the hook 230 enclose to form a first groove 250, and the mounting platform 130 is confined within the first groove 250. Optionally, the opening of the first groove 250 may face away from the mounting cavity 11, the end face of the hook 230 connected to the third end 210 may face near the inner wall of the mounting cavity 11, and the mounting platform 130 may extend radially inward along the mounting cavity 11 so that the hook 230 can be hooked onto the mounting platform 130; or, the opening of the first groove 250 may face towards the mounting cavity 11, the end face of the hook 230 connected to the third end 210 may face near the outer wall of the mounting cavity 11, and the mounting platform 130 may extend radially outward along the mounting cavity 11 so that the hook 230 can be hooked onto the mounting platform 130.

[0037] Conversely, in another embodiment (not shown), the hook 230 is connected to the second end 120, and the reinforcing rib 240 extends from the end face of the second end 120 to the end of the hook 230. The upper shell 100, the two reinforcing ribs 240, and the hook enclose to form a second groove, and the mounting platform 130 is confined within the second groove. Optionally, similar to the arrangement of the first groove 250, the opening of the second groove can face away from the mounting cavity 11, the hook 230 is connected to the end face of the second end 120 near the inner wall of the mounting cavity 11, and the mounting platform 130 extends radially inward along the mounting cavity 11 so that the hook 230 can be hooked onto the mounting platform 130; or, the opening of the second groove can face the mounting cavity 11, the hook 230 is connected to the end face of the second end 120 near the outer wall of the mounting cavity 11, and the mounting platform 130 extends radially outward along the mounting cavity 11 so that the hook 230 can be hooked onto the mounting platform 130.

[0038] It should be noted that in the above embodiments, the two reinforcing ribs 240 extend to form the first groove 250 or the second groove, which further enhances the fastening between the upper shell 100 and the lower shell 200, and improves the assembly stability and structural compactness of the entire watch protective case 10. Therefore, in this application, without giving too much consideration to the assembly stability and structural compactness of the watch protective case 10, the extension length of the reinforcing ribs 240 is not limited. It is only necessary to ensure that the two reinforcing ribs 240 are provided on the hook 230 to enhance the strength of the hook 230.

[0039] Preferably, refer to Figure 3In one embodiment, the thickness of the reinforcing rib 240 along the radial direction of the mounting cavity 11 is no greater than the thickness of the end of the hook 230. This design ensures that the reinforcing rib 240 does not excessively protrude and affect the connection stability between the hook 230 and the mounting platform 130. It should be noted that, without considering the connection stability between the hook 230 and the mounting platform 130, the protruding thickness of the reinforcing rib 240 is not limited in this application.

[0040] Preferably, in conjunction with reference Figure 2-4 In one embodiment, Figure 3 The illustration shows that both sides of the mounting plate 130 are provided with longitudinally extending limiting notches 140. The limiting notches 140 extend along the depth direction of the mounting cavity 11 to form an opening. When the upper shell 100 and the lower shell 200 are fastened together, the two reinforcing ribs 240 enter the limiting notches 140 through the openings. The two reinforcing ribs 240 are limited within the limiting notches 140 to further restrict the relative movement between the hook 230 and the mounting plate 130, thereby enhancing the assembly compactness of the entire watch protective case 10. Optionally, in one embodiment, the mounting platform 130 is located at the second end 120, and the limiting notch 140 is located at the second end 120. The limiting notch 140 extends along the depth direction of the mounting cavity 11 to the end face of the second end 120 to form an opening. The mounting cavity 11 is recessed in part of the inner wall surface of the second end 120, forming the aforementioned limiting notch 140 and the hanging groove 150. The two limiting notches 140 communicate with the opposite sides of the hanging groove 150. The hanging groove 150 and the mounting platform 130 are arranged along the hooking direction (the depth direction of the mounting cavity 11), and the hook 230 is hooked into the hanging groove 150. Of course, in another embodiment, the positions of the hook 230 and the mounting platform 130 are interchanged, and the adaptability of the positions of the limiting notch 140 and the hanging groove 150 changes.

[0041] Preferably, in one embodiment, the protrusion height of the mounting platform 130 along the radial direction of the mounting cavity 11 is no greater than the height of the limiting notch 140, so that the two reinforcing ribs 240 can be completely confined within the limiting notch 140 without protruding from the inner wall of the mounting cavity 11, and the hook 230 is hooked into the hanging groove 150 without protruding from the inner wall of the mounting cavity 11. Furthermore, the side wall of the hook 230 facing away from the mounting platform 130 smoothly contacts the inner wall of the mounting cavity 11, so that the inner wall of the mounting cavity 11 has no unevenness, enhancing the compactness of the watch head assembly on the watch case 10. Here, the hook 230 is connected to the side of the second end 120 or the third end 210 near the inner wall of the mounting cavity 11. It should be noted that, without considering the tightness of the assembly of the watch head and the watch protective case 10, the protrusion height of the hanging platform 130 is not limited in this application, as long as the hook 230 and the hanging platform 130 can be hung together; the connection position of the hook 230 at the second end 120 is also not limited.

[0042] Preferably, in conjunction with reference Figure 3 and Figure 4 At least one of the ends of the hook 230 and the mounting plate 130 is provided with a guide surface 231. The guide surface 231 extends inclined in the hooking direction. When the upper case 100 and the lower case 200 are aligned and fastened, the end of the hook 230 and the mounting plate 130 move relative to each other along the guide surface 231 until the hook 230 and the mounting plate 130 are fully engaged. It should be noted that the protruding extension of the hook 230 allows it to elastically deform and engage with the mounting plate 130. The guide surface 231 acts as a guide and buffer, reducing the deformation of the hook 230, effectively minimizing deformation damage, preventing breakage, and extending the service life of the entire watch protective case 10. Therefore, in this application, the presence or absence of the guide surface 231 is not limited.

[0043] Preferred, in conjunction with reference Figure 2 , Figure 5 and Figure 6 The second end 120 and the third end 210 each have a positioning post 160 and a positioning hole 260, respectively. The positioning post 160 extends along the depth direction of the mounting cavity 11. When the upper shell 100 and the lower shell 200 are fastened together, the positioning post 160 is aligned and fastened within the positioning hole 260. The positioning post 160 and the hook 230 are spaced apart along the side periphery of the mounting cavity 11. Optionally, the number of positioning posts 160 and positioning holes 260 are the same and correspond one-to-one, and they are spaced apart along the side periphery of the mounting cavity 11. It should be noted that here, the engagement of the positioning post 160 and the positioning hole 260 not only serves to position the upper shell 100 and the lower shell 200 during assembly, but also enhances the assembly stability of the upper shell 100 and the lower shell 200, and improves the overall assembly compactness of the watch protective case 10. Therefore, in this application, the presence or absence of positioning posts 160 and positioning holes 260 is not limited.

[0044] Preferably, in conjunction with reference Figure 1 and Figure 2In one embodiment, the first end 110 extends radially inward along the mounting cavity 11 to form a first annular step 170. The two step surfaces of the first annular step 170 are connected by curved surfaces, and the first annular step 170 is used to cover the upper surface edge of the watch head. The fourth end 220 extends radially inward along the mounting cavity 11 to form a second annular step 270. The two step surfaces of the second annular step 270 are connected by curved surfaces, and the second annular step 270 is used to cover the lower surface edge of the watch head. The user can fasten and fix the watch head in the mounting cavity 11 along the depth direction of the mounting cavity 11 using the separate upper shell 100 and lower shell 200. The first annular step 170 and the second annular step 270 can prevent the watch head from detaching from the watch protective case 10 along the depth direction of the mounting cavity 11. Optionally, in this application, the presence or absence of the first annular step 170 or the second annular step 270 is not limited, provided that the watch head is sufficiently stable to be fixed on the side of the mounting cavity 11.

[0045] Preferably, in conjunction with reference Figure 1 and Figure 2 In one embodiment, the watch case 10 includes a buffer pad 300, which is attached to the inner wall of the upper case 100 and / or the lower case 200 (the inner wall surface of the mounting cavity 11). When the user fixes the watch head in the mounting cavity 11, the buffer pad 300 separates the outer wall surface of the watch head from the inner wall surface of the mounting cavity 11, reducing friction and wear between the watch head and the upper case 100 and the lower case 200, and protecting the watch head and the watch case 10. On the other hand, the buffer pad 300 can also enhance the tightness of the assembly of the watch head fixed in the mounting cavity 11. It should be noted that in this application, the presence or absence of the buffer pad 300 is not limited.

[0046] Preferably, refer to Figure 1 In one embodiment, when the upper shell 100 is fastened to the lower shell 200, the outer surfaces of the upper shell 100 and the lower shell 200 are smoothly connected, making the watch case 10 aesthetically pleasing and preventing the user from experiencing any sharp edges. It should be noted that in this application, there is no limitation on whether the outer surfaces of the upper shell 100 and the lower shell 200 are smoothly connected.

[0047] Preferably, in conjunction with reference Figure 1 and Figure 2 In one embodiment, the third end 210 and the second end 120 are connected to form a functional hole 12. The functional hole 12 is located on the side periphery of the mounting cavity 11 and communicates with the outside of the mounting cavity 11. The functional hole 12 allows the function keys of the meter to protrude and be exposed for user operation. It should be noted that in other embodiments, the functional hole 12 can be implemented as a groove, which can also allow user operation.

[0048] 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.
