[0032] refer to Figure 1 This application provides a novel watch protective case 10, which is fitted around the outside of the watch head 20 to provide waterproof, dustproof and impact-resistant protection, thereby enhancing the security and protection of the watch head 20.
[0033] Reference Figure 1-3Specifically, the watch protective case 10 includes a housing 100 and a sleeve 200 fitted over the outside of the housing 100. The housing 100 is a hollow structure 110 with openings at both ends, providing mounting space for fixing the watch head 20. The hollow structure 110 has a first end 111 and a second end 112 arranged opposite to each other along its depth direction. The first end 111 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 watch head through the window 120. The housing 200 includes an outer sleeve 210 and an inner sleeve 220. The outer sleeve 210 is attached to the outer wall of the housing 100 opposite to the hollow structure 110, and the inner sleeve 220 is attached to the inner wall of the hollow structure 110. The outer sleeve 210 and the inner sleeve 220 are integrally formed and connected at the second end 112, forming an annular groove 230. The housing 100 is confined within the annular groove 230. The inner sleeve 220 forms a mounting cavity 240 on the side opposite to the housing 100. The depth direction of the mounting cavity 240 is parallel to the depth direction of the hollow structure 110. The mounting cavity 240 is used to position and mount the meter head 20, placing the meter head 20 between the first end 111 and the second end 112. The housing 100 and the housing 200 are made of different materials; they are integrally molded structures. Here, one of the housing 100 and the housing 200 can be made of metal, and the other can be made of plastic.
[0034] The watch protective case 10 provided in this application includes a housing 100 and a sleeve 200 covering the outside of the housing 100. Here, the housing 100 is generally made of a hard material, while the sleeve 200 is generally made of a soft material. The housing 100 and the sleeve 200 are made of different materials and are integrally molded, with a seamless fit. Therefore, the sleeve 200 not only protects the housing 100 from impact damage, but also greatly improves the overall strength, shock resistance, and sealing of the watch protective case 10, thereby enhancing its protective function and extending its service life.
[0035] Preferably, in one embodiment, reference Figure 4 The watch case 10 includes a seal 300, which is connected to the inner sleeve 220 and protrudes from the inner wall of the mounting cavity 240. When the watch case 10 is assembled onto the watch head 20, the seal 300 is located between the inner sleeve 220 and the watch head 20 to reduce the assembly gap between them, enhance the assembly compactness, and improve the sealing performance of the watch head 20 in the mounting cavity 240. It should be noted that in other embodiments, as long as the spatial contour of the mounting cavity 240 and the outer contour of the watch head 20 are sufficiently well matched, the sealing performance between them will be very strong, and the protruding seal 300 may not be necessary. Therefore, in this application, the presence or absence of the seal 300 is not limited.
[0036] Preferably, in one embodiment, reference Figure 4 The sealing element 300 is capable of elastic deformation, and the sealing element 300 and the inner sleeve 220 are integrally injection molded structures. Specifically, the sealing element 300 includes a first sealing ring 310, which surrounds the opening at the first end 111 of the mounting cavity 240 and protrudes from the inner wall of the mounting cavity 240. And / or, the sealing element 300 includes a second sealing ring 320, which surrounds the opening at the second end 112 of the mounting cavity 240 and protrudes from the inner wall of the mounting cavity 240. And / or, the sealing element 300 includes a third sealing ring 330. The inner sleeve 220 is provided with a plurality of button holes 250 communicating with the mounting cavity 240. The button holes 250 allow the side buttons of the meter 20 to pass through for user operation. The third sealing rings 330 surround the button holes 250 and protrude from the inner wall of the mounting cavity 240. The number of third sealing rings 330 and the number of button holes 250 are multiple and equal. It should be noted that the relational term "and / or" in this application refers to at least one of the following situations.
[0037] Here, the openings at both ends of the mounting cavity 240 and the button hole 250 are all channels connecting the mounting cavity 240 to the outside. Sealing the openings of the corresponding channels facing the mounting cavity 240 greatly enhances the overall sealing performance of the watch case 10. It should be noted that, firstly, without considering the sealing strength of the watch case 10, in this application, the presence or absence of sealing rings is not limited, the number of sealing rings is not limited, and the presence or absence of the first sealing ring 310, the second sealing ring 320, or the third sealing ring 330 is not limited; secondly, the sealing ring is merely a specific structure to enhance sealing performance, and in this application, the shape of the sealing element 300 is not limited.
