DETAILED DESCRIPTION
[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0033] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0036] See also Figure 1 , Figure 1 The dial in the surface structure 2 is shown. The opening in the middle is the hollow area 21 of the surface structure 2, and the surrounding ring is actually the non-hollow area 22 of the surface structure 2. The larger the opening, the larger the hollow area 21 of the surface structure 2 after assembly. The surface structure 2 needs to be installed through the surface connection mechanism 20 located in the non-hollow area 22. The surface structure 2 installation method used by the applicant in the past is to directly connect the surface connection mechanism 20 with the movement 4, so that the position of the surface connection mechanism 20 is limited by the size of the movement 4, and the size of the non-hollow area 22 from the center of the surface structure 2 is also limited by the size of the movement 4. The area of the corresponding hollow area 21 is also limited by the size of the movement 4. Especially for watches with smaller movements 4, the area of the hollow area 21 is very limited, and the hollow effect displayed is not ideal.
[0037] For example, when a watch equipped with the NH70A movement is hollowed out, if the previous method is used, due to the limitation of the size of the movement, the maximum diameter φ of the hollowed-out area 21 of the surface structure 2 can only reach 23.90 mm, resulting in the hollowed-out size of the mid-sized and male watches equipped with the NH70A movement being limited, and only a semi-hollowed-out effect can be achieved, which cannot meet the full hollowing standard, and cannot fully display and highlight the hollowed-out mechanical sense of the NH70A movement.
[0038] See also Figure 2 , the components in the table provided in the embodiment of the present application are now described. In one embodiment of the present application, the components in the table include:
[0039] Movement 4;
[0040] A fixed machine inner cover 5, on which the machine core 4 is mounted;
[0041] The auxiliary mounting member 3 is arranged on one side of the movement 4, and the auxiliary mounting member 3 and the fixed machine inner cover 5 clamp the movement 4;
[0042] The surface structure 2 is located on the side of the auxiliary mounting member 3 away from the movement 4. The surface structure 2 has a hollow area 21 and a non-hollow area 22 located on the periphery of the hollow area 21. The hollow area 21 corresponds to the movement 4. The non-hollow area 22 has a surface connection position arranged outside the area where the movement 4 is located;
[0043] The surface connection mechanism has one end connected to the surface connection position and the other end connected to the fixed machine inner cover 5 so that the auxiliary mounting part 3 and the fixed machine inner cover 5 clamp and fix the movement 4.
[0044] The components inside the watch are components located inside the watch case, and mainly include the movement 4, the fixed inner cover 5, the surface structure 2 and other parts. The movement 4 is the core component of the watch and is responsible for driving the operation of the watch. The fixed inner cover 5 is used to fix and protect the movement 4. The surface structure 2 usually includes a dial and corresponding auxiliary structures. For example, the surface structure 2 in the figure includes a dial, a transparent decorative layer, scales and other parts. For a hollow watch, the surface structure 2 includes a hollow area 21 and a non-hollow area 22. The hollow area 21 is used to hollow out the movement 4, and the non-hollow area 22 is connected to a surface connection mechanism 20 to achieve the installation of the dial.
[0045] The surface structure 2 of this embodiment is not directly mounted on the movement 4, but an auxiliary mounting part 3 is arranged on one side of the movement 4 where the surface structure 2 is mounted. The auxiliary mounting part 3 can be a ring-shaped structure, a structure of multiple arc segments, etc. The movement 4 is located between the auxiliary mounting part 3 and the fixed machine inner cover 5. At the same time, the surface connection mechanism 20 of the surface structure 2 is connected to the fixed machine inner cover 5, so that the auxiliary mounting part 3 and the fixed machine inner cover 5 clamp and fix the movement 4. In this way, the surface connection position and the surface connection mechanism 20 can be arranged outside the movement 4. Because the surface connection position is arranged in the non-hollow area 22 of the surface structure 2, the position of the non-hollow area 22 is no longer limited by the size of the movement. The non-hollow area 22 can be expanded outward, and the hollow area 21 therein is no longer limited by the size of the movement 4, and the area can be expanded, thereby improving the hollowing performance effect. Especially for watches whose hollowing area is affected by the small movement 4, the effect is very significant.
[0046] See also Figure 6 In one embodiment of the present application, a first positioning structure is provided between the auxiliary mounting member 3 and the movement 4 to position the relative positions of the auxiliary mounting member 3 and the movement 4. The first positioning structure may adopt a structure of a boss and a groove, a pin and a hole, etc. For example, there may be one or more bosses on the movement 4, and there are matching grooves on the auxiliary mounting member 3. This structure ensures accurate alignment between the auxiliary mounting member 3 and the movement 4 through the close fit of the boss and the groove.
[0047] The first positioning structure can ensure the relative fixation of the positions of the auxiliary mounting member 3 and the movement 4. On the one hand, it can ensure the stability of the installation of the movement 4 and the auxiliary mounting member 3. On the other hand, for the auxiliary mounting member 3 with decorative effect, it can ensure its correct installation direction, thereby accurately displaying the preset effect.
[0048] See also Figure 6 In one embodiment of the present application, the first positioning structure includes a first positioning column, which is connected to the auxiliary mounting part 3. The movement 4 is provided with a first positioning hole 43, and the first positioning column is inserted into the first positioning hole 43. The first positioning column is a protruding structure, which can be cylindrical or even square column-shaped. The first positioning column can be connected to the auxiliary mounting part 3 by welding, threaded connection or integral molding. The first positioning hole 43 is a hole in the movement 4 corresponding to the first positioning column, and the shape and size match the first positioning column to facilitate the insertion of the first positioning column. When the first positioning column is inserted into the first positioning hole 43, the positioning between the auxiliary mounting part 3 and the movement 4 can be achieved. The number of the first positioning column and the corresponding first positioning hole 43 can be one or more. The embodiment shown in the figure uses two first positioning columns and the first positioning holes 43 that match them.
[0049] See also Figure 6 In one embodiment of the present application, the auxiliary mounting member 3 is an annular structure. In addition to the annular structure, the auxiliary mounting member 3 can also adopt multiple arc segments, or even a circular transparent structure, etc. In comparison, the annular structure can not only better show the hollow design of the movement 4, but also has stronger stability, which can ensure the stability of the installation of the movement 4 and the surface structure 2.
[0050] See also Figure 4 In one embodiment of the present application, a first annular positioning groove 31 is provided on the side of the auxiliary mounting member 3 facing the movement 4, and a first step portion 41 is provided on the edge of the movement 4 facing the auxiliary mounting member 3. The first step portion 41 is arranged in the first annular positioning groove 31. In this embodiment, since the auxiliary mounting member 3 is an annular structure, a first annular positioning groove 31 can be provided thereon. The first annular positioning groove 31 can provide a positioning function for the installation of the movement 4. The first step portion 41 is formed by using the upper edge of the movement 4. The first step portion 41 of the movement 4 is aligned with the first annular positioning groove 31 for installation. This can ensure that the movement 4 and the auxiliary mounting member 3 are positioned more accurately, prevent relative movement or misalignment between them, and ensure the stability and reliability of the product.
[0051] See also Figure 4In one embodiment of the present application, a second annular positioning groove 52 is provided inside the fixed machine inner cover 5, and a second step portion 42 is correspondingly provided on the outer periphery of the movement 4, and the second step portion 42 is arranged in the second annular positioning groove 52. The second annular positioning groove 52 can also provide a positioning function for the movement 4. Aligning the second step portion 42 of the movement 4 with the second annular positioning groove 52 can ensure that the movement 4 and the fixed machine inner cover 5 are more accurately positioned, prevent relative movement or misalignment between them, and ensure the stability and reliability of the product.
[0052] In addition, the fixed machine inner cover 5 and the auxiliary mounting part 3 can also directly clamp the upper and lower edges of the movement 4. However, in comparison, the first annular positioning groove 31 and the second annular positioning groove 52 can play a positioning role. The movement 4 is clamped up and down by the first annular positioning groove 31 of the auxiliary mounting part 3 and the second annular positioning groove 52 of the fixed machine inner cover 5, which not only can ensure the stability and accuracy of the installation of the movement 4, but also can better protect the movement 4.
[0053] See also Figure 4 In one embodiment of the present application, a third limit portion 53 is provided on one side of the fixed machine inner cover 5 close to the auxiliary mounting member 3, and the auxiliary mounting member 3 has an extension portion 32 extending to the third limit portion 53, and the extension portion 32 abuts against the third limit portion 53. The movement 4 is clamped and fixed by the fixed machine inner cover 5 and the auxiliary mounting member 3. In this embodiment, the third limit portion 53 of the fixed machine inner cover 5 and the extension portion 32 of the auxiliary mounting member 3 abut against each other, thereby limiting the clamping distance between the fixed machine inner cover 5 and the auxiliary mounting member 3, thereby preventing the fixed machine inner cover 5 and the auxiliary mounting member 3 from excessively clamping and damaging the movement 4.
[0054] See also Figure 4 In one embodiment of the present application, the auxiliary mounting part 3 has a revealing portion 33, the projection of the revealing portion 33 in the direction of the central axis of the surface structure 2 is located in the hollow area 21, and the revealing portion 33 is provided with a decorative structure. The surface structure 2 of the present application is not directly connected to the movement 4, but the auxiliary mounting part 3 and the fixed machine inner cover 5 are connected through the surface connection mechanism 20 to clamp and fix the movement 4. Therefore, after the hollow area 21 is enlarged, the auxiliary mounting part 3 may be partially exposed in the hollow area 21, that is, the revealing portion 33 of the auxiliary mounting part 3 is formed. In order to increase the aesthetics, in this embodiment, the revealing portion 33 is provided with a decorative structure. The decorative structure can be a surface engraved on the watch or a hollow pattern, a decorative effect formed by polishing, color change, etc., which can make the movement 4 achieve color change and the effect of enlarging the hollow area 21, so that the combination of the movement 4 with the housing 1 and the surface is more perfect, and it stands out among watches equipped with similar movements 4. The internal components of the present application can be used in clock products such as watches and pocket watches.
[0055] See also Figure 3 and Figure 4In one embodiment of the present application, the surface connection mechanism 20 includes a second positioning column 23 and a fastener 24, the second positioning column 23 is connected to the non-hollow area 22 of the surface structure 2, the fixed machine inner cover 5 is provided with a second positioning hole 51, the second positioning column 23 is inserted into the second positioning hole 51, and the fastener 24 is connected to the second positioning column 23 to limit the second positioning column 23 in the depth direction of the second positioning hole 51.
[0056] The surface connection mechanism 20 is used to connect the surface structure 2 with the fixed machine inner cover 5. While realizing the installation of the surface structure 2, the auxiliary mounting member 3 and the fixed machine inner cover 5 can be clamped and fixed to the movement 4. The surface connection mechanism 20 can be in the form of screws, buckle structures, etc. In this embodiment, the surface connection mechanism 20 includes a second positioning column 23 and a fastener 24, wherein the second positioning column 23 is inserted into the second positioning hole 51 on the fixed machine inner cover 5 to play a positioning function and ensure the accuracy of the position and direction of the surface structure 2 installation. The fastener 24 is connected to the second positioning column 23 to limit the second positioning column 23 in the second positioning hole 51 so that it will not disengage. The fastener 24 can be a screw, a pin or other types of fasteners 24. By using the fastener 24, it can be ensured that the connection between the surface structure 2 and the fixed machine inner cover 5 is more stable and reliable.
[0057] During the assembly process, the second positioning column 23 is inserted into the second positioning hole 51 and then fixed by the fastener 24. This insertion and fastening method not only ensures that the relative position between the surface structure 2 and the fixed machine inner cover 5 is accurate, and improves the overall stability and reliability of the watch, but also, compared with the method of directly connecting the surface structure 2 and the fixed machine inner cover 5 with screws or bolts, the fastening force of the fastener 24 will not directly act on the surface structure 2 and the fixed machine inner cover 5, which can prevent the surface structure 2, the fixed machine inner cover 5 and the movement 4 from being damaged during the assembly process.
[0058] See also Figures 2 to 5 The present application further provides a watch based on the above-mentioned internal watch components, and the watch comprises a housing 1 and the above-mentioned internal watch components, and the internal watch components are arranged in the housing 1. The housing 1 is the main outer shell component of the watch, which plays the role of protecting and containing the internal parts of the watch, and usually mainly comprises a main housing, a watch mirror, a bottom cover, a crown and other structures. The above-mentioned internal watch components are correctly installed in the watch case, so that the surface structure 2 faces the watch mirror, and the crown is connected to the movement 4 through the bar tube 9, so that the main structure of the watch can be formed.
[0059] See also Figure 5In one embodiment of the present application, a fourth limiting portion 11 is provided at the edge of the shell 1 corresponding to the surface structure 2, and the edge of the surface structure 2 abuts against the fourth limiting portion 11; at least two fixed cover gaskets 7 are circumferentially provided on the solid machine inner cover 5, and an inner cover fixing groove 12 is provided on the shell 1 corresponding to the position of the fixed cover gasket 7, one end of the fixed cover gasket 7 is connected to the solid machine inner cover 5, and the other end is clamped in the inner cover fixing groove 12.

The number of the fixed cover gaskets 7 is at least two, and can be more, to ensure the stability of the installation. The fixed cover gasket 7 and the fixed machine inner cover 5 can be connected by screws, plug-in, snap-in, etc. One side of the internal component of the meter is abutted against the fourth limiting portion 11 through the surface structure 2, and the other side is snapped into the inner cover fixing groove 12 of the shell 1 through the fixed cover gasket 7 of the fixed machine inner cover 5. The internal component of the meter is stably installed in the casing through the limiting on both sides.
