Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0049] In the embodiments of the present application, unless otherwise clearly specified and limited, terms such as "installation", "connection", "linkage", "fixation" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral one; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0050] According to an embodiment of the first aspect of the present application, as shown in Figures 1-8 the hand surface case structure provided by the present application includes: a frame body 1 and a face cover 2 sleeved on the frame body 1, and a first connection structure 3 is provided at the edge of the frame body 1. The first connection structure 3 includes a first groove 4 and a through-hole structure 5, and the through-hole structure 5 communicates with the bottom of the first groove 4.

[0051] A second connection structure 6 is provided at the edge of the face cover 2. The second connection structure 6 includes a connected first boss portion 7 and a connection portion 8. The first boss portion 7 is adaptively connected in the first groove 4, and the connection portion 8 is adaptively connected in the through-hole structure 5.

[0052] In this embodiment of the present application, the frame body 1 is one of the main components constituting the hand surface case, and it plays a role in supporting the entire surface case structure. The edge of the frame body 1 is designed with a first connection structure 3, including a first groove 4 and a through-hole structure 5. The first groove 4 is designed to accommodate the first boss portion 7 on the face cover 2. The through-hole structure 5 is located at the bottom of the first groove 4 and is connected to it.

[0053] The face cover 2 covers the frame body 1 and mainly plays a decorative role to improve the overall aesthetics of the watch. A second connection structure 6 is provided at the edge of the face cover 2, including a first boss portion 7 and a connection portion 8. The first boss portion 7 is adapted to the first groove 4 on the frame body 1 and is placed therein. The connection portion 8 is adapted to the through-hole structure 5 on the frame body 1 to further enhance the connection strength.

[0054] The face cover 2 is directly formed on the frame body 1 through the overmolding process. For example, the specific steps of the overmolding process may include:

[0055] Prepare the frame body 1 as a preform. The frame body 1 can be made of metal or other suitable materials.

[0056] Heat the mold to an appropriate temperature to soften the face cover material to be injected. The face cover material can be, for example, a soft material such as thermoplastic elastomer or thermoplastic polyurethane.

[0057] Place the frame body 1 in the appropriate position in the mold to ensure its stability and correct alignment.

[0058] Inject the molten face cover material into the mold so that it flows around the frame 1 and fills the predetermined space.

[0059] The material cools and solidifies to form a solid integral structure.

[0060] When the material is completely solidified, open the mold and remove the finished product.

[0061] Perform necessary subsequent processing on the product, such as trimming the edges, cleaning, etc.

[0062] Through this process, the face cover 2 and the frame 1 are tightly combined into a whole, which helps to improve the sealing performance and durability of the connection part.

[0063] Moreover, through the cooperation between the first boss portion 7 and the first groove 4, and the cooperation between the connecting portion 8 and the through-hole structure 5, multi-point fixation is achieved, increasing the stability and tightness of the connection, and reducing the risk of damage caused by collision or dropping. This design not only enhances the strength of the mechanical connection, but also effectively improves the waterproof performance due to the existence of multiple contact points.

[0064] Due to the multi-point tight connection between the face cover 2 and the frame 1, the deficiencies that may exist in traditional sealing rings, such as aging, displacement, or incomplete fitting, are reduced. This structure can better resist the entry of external moisture and dust, improving the overall waterproof and sealing performance of the watch.

[0065] Therefore, the watch case structure provided by the embodiment of the present application, by adopting the insert molding process and a more compact multi-point connection structure, increases the insert molding path between the face cover 2 and the frame 1, enlarges the connection area during insert molding, makes the connection between the two more tight and firm, thereby improving the overall waterproof performance of the watch. This design not only simplifies the sealing link in the assembly process, but also reduces the failure rate caused by poor sealing, improving the reliability and service life of the product.

[0066] According to an embodiment of the present application, referring to Figures 3-6 As shown, the through-hole structure 5 of the frame 1 includes: a first channel 9 and a second channel 10. The first channel 9 communicates with the bottom of the first groove 4 in the first direction; the second channel 10 communicates with the first channel 9 in the second direction; the first direction and the second direction have an included angle.

[0067] In this embodiment of the present application, the first channel 9 extends from the bottom of the first groove 4 along the first direction (for example, the height direction Z of the frame 1). It provides a connection channel in the height direction Z between the face cover 2 and the frame 1.

[0068] The second hole 10 extends from the end of the first hole 9 away from the first groove 4 along the second direction (for example, the width direction Y toward the inside of the frame 1). This design allows the cover 2 and the frame 1 to also have a connecting channel in the width direction Y. For example, the through hole structure 5 is generally L-shaped.

[0069] By providing the first hole 9 and the second hole 10 on the frame 1, the beer-insertion molding path between the cover 2 and the frame 1 is increased. During the beer-insertion molding process, the molten cover material will not only fill the first hole 9 in the height direction Z, but also fill the second hole 10 along the width direction Y, thereby forming a more complex three-dimensional connection structure. This structural design increases the contact area between the cover 2 and the frame 1. A larger contact area means a stronger physical connection, thereby improving the stability of the connection, reducing potential leakage paths, and improving the waterproof performance.

[0070] Therefore, the embodiment of the present application not only improves the connection strength between the cover 2 and the frame 1 through the through-hole structure 5, but also greatly enhances the overall waterproof performance of the watch.

[0071] According to one embodiment of the present application, referring to Figures 3-8 As shown, the connecting portion 8 of the face cover 2 includes: a first connecting portion 11 and a second connecting portion 12, the first connecting portion 11 is connected to the bottom of the first boss portion 7, and the first connecting portion 11 is adaptively connected to the first channel 9; the second connecting portion 12 is connected to the first connecting portion 11, and the second connecting portion 12 is adaptively connected to the second channel 10.

[0072] In this embodiment of the present application, the first connection part 11 is connected to the bottom of the first boss part 7. The first connection part 11 is adapted to the first hole 9 on the frame 1, that is, during the beer forming process, the first connection part 11 will fill the first hole 9 to form a connection in the height direction Z.

[0073] The second connection portion 12 is connected to the end of the first connection portion 11 away from the first boss portion 7. The second connection portion 12 is adapted to the second channel 10 on the frame 1, that is, during the beer forming process, the second connection portion 12 will fill the second channel 10 to form a connection in the width direction Y. For example, the connection portion 8 is generally L-shaped.

[0074] The embodiment of the present application increases the contact surface between the cover 2 and the frame 1 by designing the first connection part 11 and the second connection part 12, forming a multi-dimensional connection structure. This specially designed connection structure not only improves the connection strength between the cover 2 and the frame 1, but also greatly enhances the overall waterproof performance of the watch.

[0075] According to an embodiment of the present application, a texture structure is provided on the groove wall of the first groove 4 .

[0076] For example, the texture structure can be a spark pattern. The spark pattern is a surface treatment process that can increase the roughness of the material surface, thereby improving the friction and adhesion, making the connection after sleeve beer forming more firm and enhancing the waterproof sealing performance.

[0077] Of course, the texture structure can also be stripes, grids, waves and other structures. It can be specifically designed and adjusted according to actual needs.

[0078] According to an embodiment of the present application, referring to Figures 1-6 as shown, the frame body 1 includes: a main body 13 and an annular flange 14, and the face cover 2 is covered on the main body 13; the annular flange 14 is arranged at the inner edge of the main body 13, and a first connection structure 3 is arranged on the annular flange 14.

[0079] Specifically, by integrating the first connection structure 3, that is, the first groove 4 and the through-hole structure 5, on the annular flange 14, the need for additional components is reduced, making the overall structure more compact. This design simplifies the assembly process and improves production efficiency.

[0080] And, as Figure 9 shown, an adhesive can also be applied on the annular flange 14 to bond the display panel 25 of the watch to the annular flange 14, ensuring a tight connection between the display panel 25 and the frame body 1.

[0081] Due to the bonding between the annular flange 14 and the display panel 25, and the tight connection between the face cover 2 and the frame body 1, the whole structure forms an effective waterproof barrier. This design helps to prevent moisture and dust from entering the watch interior and improves the overall waterproof performance of the watch.

[0082] According to an embodiment of the present application, referring to Figure 4 、 Figure 5 and Figure 8 as shown, the first connection structure 3 of the frame body 1 further includes a second groove 15, the second groove 15 is arranged on the side of the annular flange 14 adjacent to the main body 13, and the second groove 15 extends along the length direction X and / or the width direction Y of the annular flange 14, the first groove 4 is arranged in the extending direction of the second groove 15, and the first groove 4 is communicated with the second groove 15; the second connection structure 6 of the face cover 2 further includes a second boss portion 16 connected to the first boss portion 7, and the second boss portion 16 is adaptively connected in the second groove 15, that is, during the sleeve beer forming process, the second boss portion 16 will fill the second groove 15 to form an additional connection.

[0083] There is no special limitation on the specific number of the first grooves 4 arranged in the extending direction (length direction X and / or width direction Y) of the second groove 15 in the present application. For example, the number of the second grooves 15 can be at least two, and the second grooves 15 are arranged at intervals.

[0084] Specifically, by providing a second groove 15 on the annular flange 14 of the housing 1 and designing a corresponding second boss portion 16 on the face cover 2, the overmolding path between the face cover 2 and the housing 1 is further increased, and the connection area between the face cover 2 and the housing 1 is enlarged. A larger contact area means a stronger physical connection, thereby improving the connection stability and significantly enhancing the waterproof sealing performance.

[0085] According to an embodiment of the present application, referring to Figure 5 as shown, the groove width of the second groove 15 is smaller than that of the first groove; and / or, the bottom of the second groove 15 is higher than or lower than the bottom of the first groove 4.

[0086] In this embodiment of the present application, the shape of the first groove 4 can be approximately square, for example, to accommodate the first boss portion 7 on the face cover 2.

[0087] The shape of the second groove 15 can be approximately elongated, for example. The groove width of the second groove 15 is smaller than that of the first groove 4, and the bottom position of the second groove 15 can be higher than or lower than the bottom position of the first groove 4, for accommodating the second boss portion 16 on the face cover 2.

[0088] By designing grooves with different heights and sizes in the embodiments of the present application, a multi-layer connection structure can be formed. This combination of designs helps to form a more complex overmolding connection path and improves the waterproof performance.

[0089] According to an embodiment of the present application, referring to Figures 3-5 as shown, the top of the main body 13 of the housing 1 has a first curved wall 17; the face cover 2 includes a cover body 18, and a second connection structure 6 is provided on the inner edge of the cover body 18. The bottom of the cover body 18 has a second curved wall 19 that is adaptively connected to the first curved wall 17.

[0090] In this embodiment of the present application, the first curved wall 17 is provided at the top of the main body 13 of the housing 1, and its shape can be designed as a wavy or other form of curved structure.

[0091] The second curved wall 19 is provided at the bottom of the cover body 18 of the face cover 2, and its shape is adapted to the first curved wall 17. Similarly, it can be designed as a wavy or other form of curved structure.

[0092] By designing curved walls, especially wavy curved walls, the sealing performance between the face cover 2 and the housing 1 can be further improved. The wavy curved wall can form multiple sealing points between the face cover 2 and the housing 1, reducing the possibility of moisture and dust entering.

[0093] Moreover, the design of the curved wall increases the contact area between the face cover 2 and the housing 1. A larger contact area means a stronger physical connection, thereby improving the connection stability.

[0094] According to an embodiment of the present application, with reference to Figure 3 As shown, the outer edge of the main body 13 has a first side wall 20 connected to the first curved wall 17, and a third groove 21 is provided at the bottom of the first side wall 20; the face cover 2 further includes a second side wall 22, the second side wall 22 is provided at the outer edge of the cover body 18 and covers the first side wall 20, and a third boss portion 23 is provided at the bottom of the second side wall 22, and the third boss portion 23 is adaptively connected to the third groove 21. That is, during the sleeve beer molding process, the third boss portion 23 will fill the third groove 21 to form an additional connection.

[0095] Specifically, by providing the third groove 21 on the first side wall 20 of the frame body 1 and designing the corresponding third boss portion 23 on the second side wall 22 of the face cover 2, the sleeve beer molding path between the face cover 2 and the frame body 1 is increased, and the connection area between the face cover 2 and the frame body 1 is increased. A larger contact area means a stronger physical connection, thereby improving the connection stability and significantly improving the waterproof sealing performance.

[0096] According to an embodiment of the second aspect of the present application, with reference to Figure 9 As shown, the present application further provides a watch, including: a bottom case 24, a display panel 25, and the watch surface case structure of the above embodiment.

[0097] Specifically, the frame body 1 of the watch surface case structure is connected to the bottom case 24, the face cover 2 of the watch surface case structure is sleeve-beer molded on the frame body 1, and the display panel 25 is bonded to the annular flange 14 of the frame body 1, thereby forming a sealed accommodation cavity, and components such as a battery, a movement, a pointer, and a dial can be arranged in the accommodation cavity.

[0098] The watch provided by the embodiment of the present application can effectively improve the overall waterproof sealing performance and avoid waterproof failure through the watch surface case structure of the above embodiment, thereby improving the reliability of the product.

[0099] The above are only the preferred embodiments of the present application and are not used to limit the embodiments of the present application.
