[0031] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "setup," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] refer to Figure 1 This application provides a novel watch protective case 10, including a protective sleeve 100 and a decorative ring 200. The protective sleeve 100 wraps around the watch head to enhance its waterproof, dustproof and impact-resistant protection functions, while the decorative ring 200 is mounted on the protective sleeve 100 to increase the aesthetics of the watch head.

[0035] Reference Figure 1-3 Specifically, the protective cover 100 has a mounting cavity 110 for fixing and mounting the meter head. The mounting cavity 110 has a front end 111 and a back end 112 disposed opposite to each other along the depth direction of the mounting cavity 110. The front end is provided with a light-transmitting window 120, which can be an opening or a transparent protective film, allowing the user to view the display screen of the meter head through the window 120. The protective cover 100 positions the meter head within the mounting cavity 110 and positions the meter head between the front end 111 and the back end 112. A decorative ring 200 is attached to the outside of the protective cover 100 along the edge of the window 120 and is located on one side of the front end 111. The decorative ring 200 is made of a different material than the protective cover 100, and the decorative ring 200 and the protective cover 100 are integrally molded. Here, one of the protective cover 100 and the decorative ring 200 can be made of metal, and the other can be made of plastic.

[0036] Because the protective case 100 and decorative ring 200 of this application are made of different materials and are molded as a single unit, their individual processing and design do not affect each other. Furthermore, the seamless fit between the protective case 100 and decorative ring 200 greatly improves the sealing of the watch case 10 with decorative ring 200 and the overall compactness of the watch case 10. Compared to structures where the protective case 100 and decorative ring 200 are detachable, this design is more robust and less prone to damage. This extends the service life of the watch case 10, thus giving the watch case 10 of this application superior aesthetics and practicality.

[0037] Preferably, in one embodiment, in conjunction with reference to Figure 4 and Figure 5 The protective case 100 has a first annular step 130 on its outer wall near the positive end 111. The first annular step 130 includes a first step annular surface 131 and a second step annular surface 132 set at an angle. The second step annular surface 132 is connected to the first step annular surface 131 and extends towards the positive end 111. The decorative ring 200 includes a bottom annular surface 210 and a first inner annular surface 220. The bottom annular surface 210 is attached to the first step annular surface 131, and the first inner annular surface 220 is attached to the second step annular surface 132. Furthermore, the outer wall of the decorative ring 200 is flush with the outer wall of the protective case 100. It should be noted that "flush" here means that the decorative ring 200 does not protrude from the side wall of the protective case 100 in the radial direction along the mounting cavity 110. This makes the outer side of the entire watch protective case 10 more aesthetically pleasing and free of any sharp edges. It should be noted that, without considering the possibility that the outer wall of the watch case 10 might cut the hand, this application does not limit whether the outer wall of the decorative ring 200 is flush with the outer wall of the protective case 100.

[0038] Preferably, in one embodiment, in conjunction with reference to Figure 4 and Figure 5 The inner wall of the decorative ring 200 includes a second inner annular surface 230 that surrounds the mounting cavity 110 circumferentially, and the second inner annular surface 230 is attached to the end face of the positive end 111.

[0039] Preferably, in one embodiment (the second embodiment), in conjunction with reference to... Figure 6-9 The protective sleeve 100 has an inner conical surface 140 recessed into the mounting cavity 110 at the positive end 111. The inner sidewall of the decorative ring 200 includes a third inner annular surface 240 extending circumferentially. The first inner annular surface 220, the second inner annular surface 230, and the third inner annular surface 240 are connected in sequence, and the third inner annular surface 240 is attached to the inner conical surface 140.

[0040] It should be noted that in this application, the decorative ring 200 serves a decorative purpose. The decorative ring 200 is attached to the outer wall of the protective sleeve 100 on the side where the main end 111 is located. Depending on the aesthetic effect, the position of the decorative ring 200 attached to the main end 111 is not limited, as long as it is attached in a ring around the mounting cavity 110. Therefore, in this application, the presence or absence of the first inner annular surface 220, the second inner annular surface 230, or the third inner annular surface 240 is not limited, depending on the attachment method of the decorative ring 200. Similarly, the presence or absence of the first annular step 130 or the inner conical surface 140 is not limited, depending on the shape design of the main end 111. In this application, the simplest attachment method is to attach the decorative ring 200 to the horizontal end face of the main end 111 or the outer wall of the protective sleeve 100 to achieve a decorative and aesthetic purpose.

[0041] Preferably, in one embodiment, reference Figure 3 or Figure 7 The viewing window 120 includes tempered glass 121, which serves as a transparent protective film for the user to view the display screen of the meter. Figure 4 or Figure 8 The illustration shows that the tempered glass 121 is embedded in the mounting cavity 110 and covers the opening at the front end 111. It should be noted that in other embodiments, the viewing window 120 can also be an opening without any obstruction, allowing the user to view the display screen of the watch head through the opening. Therefore, in this application, the presence or absence of tempered glass 121 is not limited.

[0042] Preferably, in one embodiment, in conjunction with reference to Figure 4 and Figure 5The mounting cavity 110 has a second annular step 150 on the inner wall of the positive end 111. The second annular step 150 includes a third step annular surface 151 and a fourth step annular surface 152 arranged at an angle. The third step annular surface 151 and the fourth step annular surface 152 are connected and extend towards the positive end 111. In the radial direction along the mounting cavity 110, the outer wall of the decorative ring 200 facing the mounting cavity does not protrude from the third step annular surface 151, and the side periphery of the tempered glass 121 simultaneously abuts against the outer wall of the decorative ring 200 facing the mounting cavity 110 and the third step annular surface 151. In the depth direction along the mounting cavity 110, the bottom edge portion of the tempered glass 121 is attached to the fourth step annular surface 152 to cover the opening of the positive end 111. The second annular step 150 further enhances the assembly stability of the tempered glass 121. Furthermore, the upper surface of the tempered glass 121 is flush with the outer surface of the decorative ring 200 away from the protective sleeve 100. Here, "flush" means that, along the depth direction of the mounting cavity 110, the tempered glass 121 does not protrude from the decorative ring 200, so that the entire watch case 10 does not feel sharp to the touch on the upper surface of the tempered glass 121, further enhancing its aesthetics. It should be noted that, firstly, without considering the assembly stability of the tempered glass 121, the presence or absence of the second annular step 150 is not limited in this application; secondly, without considering the sharpness of the watch case 10, whether the upper surface of the tempered glass 121 is flush with the outer surface of the decorative ring 200 away from the protective sleeve 100 is not limited in this application.

[0043] Preferably, in one embodiment, reference Figure 10 The mounting cavity 110 also has a second annular step 150 on the inner wall of the positive end 111. The second annular step 150 includes a third step annular surface 151 and a fourth step annular surface 152 arranged at an angle. The third step annular surface 151 and the fourth step annular surface 152 are connected and extend toward the positive end 111. In the radial direction along the mounting cavity 110, the decorative ring 200 is attached to the third step annular surface 151 and the fourth step annular surface 152 in sequence, and the side peripheral wall of the tempered glass 121 abuts against the decorative ring 200. In the depth direction along the mounting cavity 110, the bottom edge portion of the tempered glass 121 is attached to the decorative ring 200 to cover the opening of the positive end 111. The decorative ring 200 separates the tempered glass 121 from the protective sleeve 100. The tempered glass 121 does not directly contact the protective sleeve 100 but is only attached to the decorative ring 200. The tempered glass 121 only contacts one material surface, reducing the ease of attachment. It should be noted that, without considering the difficulty of attaching the tempered glass 121, in this application, the contact position range between the decorative ring 200 and the end face of the front end 111 is not limited, nor is it limited whether the tempered glass 121 contacts the protective sleeve 100; it is only required that the decorative ring 200 is attached to the outer side of the front end 111.

[0044] Preferably, in one embodiment, in conjunction with reference to Figure 8 and Figure 9 The protective sleeve 100 extends radially inward along the mounting cavity 110, forming an annular boss 160. The upper surface of the side peripheral edge of the tempered glass 121 is attached to the bottom surface of the annular boss 160, and the side peripheral of the tempered glass 121 abuts against the inner wall of the mounting cavity 110. The tempered glass 121 is recessed into the end face of the positive end 111. Here, after the user installs the watch head on the watch protective case 10, the tempered glass 121 is sandwiched between the watch head and the annular boss 160 radially along the mounting cavity, making it less likely to fall off, thus improving the assembly stability of the tempered glass 121. It should be noted that in other embodiments, the outer surface of the tempered glass 121 is bonded to the attachment surface of the protective sleeve 100, and the side peripheral wall of the tempered glass 121 is interference-fitted with the inner wall of the mounting cavity 110, which also enhances the assembly stability of the tempered glass 121. Therefore, in this application, firstly, the presence or absence of the annular boss 160 is not limited; secondly, whether the side wall of the tempered glass 121 and the inner wall of the mounting cavity 110 are interference-fitted is not limited, and they can be completely bonded. It is sufficient to fix the tempered glass 121 within the mounting cavity 110. Finally, the window 120 includes a buffer transparent pad 122 attached to the back of the tempered glass 121. The buffer transparent pad 122 is used to separate the back of the tempered glass film 121 from the display surface of the watch head, reducing contact friction and wear between the two, thereby simultaneously protecting both the tempered glass film 121 and the display surface of the watch head. It should be understood that, without considering friction and wear, the presence or absence of the buffer transparent pad 122 is not limited in this application.

[0045] 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.
