Description

Technical Field

[0001] The utility model relates to the technical field of watches, in particular to a watch shockproof structure, a watch head and a watch. Background Art

[0002] Due to the limited thickness of mechanical movements, some small watches are thicker than quartz watches. To achieve a visually thinner appearance, some watches achieve this by enlarging the top surface and reducing the bottom. To adapt to various lifestyles and exercise needs, watches often require excellent shock resistance to prevent malfunction or failure due to shock. However, this watch structure significantly reduces the space at the bottom of the case, making it impossible to design complex shock-absorbing structures to protect the movement. Currently, these watches on the market primarily use two types of inner covers: plastic and metal. In the former, the inner cover is supported by the bottom cover, directly pressing against the movement. The movement then presses against the dial, forcing the dial against the case, achieving internal fixation. In this structure, because the upper portion of the movement is directly pressed against the dial, impacts can directly impact the dial, causing deformation and, in severe cases, affecting the movement of the hands. This results in poor shock resistance. The latter is fixed by the movement locking screws and the fixing plate; in this structure, since the metal inner cover and the fixing plate, the fixing screws and the movement splint are themselves metal parts, a rigid fit is adopted, and the movement relies on the fixing plate and the metal inner cover to clamp and fix the movement splint. The fixing plate and the fixing screws are small in size. When subjected to long-term vibration or impact, the screws are prone to breakage or falling off. The stability of the inner cover structure is insufficient, and the assembly process of this type of inner cover structure is complicated, which further increases the difficulty of assembling the watch.

The movement can be inserted into the inner space of the annular inner cover, and the annular inner cover is inserted into the support position of the watch case to realize the installation of the movement on the watch case, which reduces the difficulty of assembling the movement.

[0022] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Please combine Figure 1-4The utility model discloses a watch shockproof structure 100 with good shockproof performance, stable structure and simple assembly. The watch shockproof structure 100 includes an annular inner cover 110, a movement limiting assembly and a case limiting assembly. The annular inner cover 110 is used to be arranged between the movement 200 and the case 300. The movement limiting assembly and the case limiting assembly are both fixed on the annular inner cover 110. The movement limiting assembly is used to limit the movement 200, and the case limiting assembly is used to limit the case 300. In this way, through the cooperation between the movement limiting assembly on the annular inner cover 110 and the movement 200, and the cooperation between the case limiting assembly and the case 300, the stable installation of the movement 200 on the case 300 is achieved. In this embodiment, the movement limiting assembly, the case limiting assembly, and the annular inner cover 110 are integrally formed, and the watch shockproof structure 100 is entirely made of a plastic material, for example, PC, PE, PVC, or PMMA. This provides elasticity to some components of the movement limiting assembly and the case limiting assembly while reducing the overall weight and processing cost of the watch shockproof structure 100. After the annular inner cover 110 is assembled with the movement 200, the upper end surface of the annular inner cover 110 is flush with the upper surface of the movement 200. In this way, when the movement 200 is installed in the case 300 and matched with the dial, the upper end surface of the annular inner cover 110 and the upper surface of the movement 200 can simultaneously fit with the lower surface of the dial, thereby reducing the shaking of the annular inner cover 110 and the movement 200 within the case 300.

[0024] The movement limiting assembly includes at least one first boss 120 arranged on the inner ring surface of the annular inner cover 110 and used to abut against the ring side surface of the movement 200, a plurality of second bosses 130 arranged at intervals on the inner ring surface of the annular inner cover 110 and adjacent to the upper end surface of the annular inner cover 110, and a plurality of barbed hook-type buckles 140 arranged at intervals on the lower end surface of the annular inner cover 110. The lower surface of the second boss 130 abuts against the edge of the upper surface of the movement 200, and the buckle 140 has a first protrusion 141 protruding toward the center of the annular inner cover 110 and used to support the plate support position of the movement 200. In this embodiment, the first boss 120 is used to press against the annular side surface of the movement 200 to achieve radial (diameter direction of the movement 200) limitation of the movement 200; the first protrusion 141 on the buckle 140 and the second boss 130 jointly clamp the movement 200 to achieve axial (height direction of the movement 200) limitation of the movement 200.

[0025] The case retaining assembly includes a plurality of spring clips 150 spaced apart and fixed to the lower end surface of the annular inner cover 110, adjacent to the inner surface of the annular inner cover 110; and a plurality of elastic legs 160 fixed to the lower end surface of the annular inner cover 110, corresponding to each spring clip 150 and adjacent to the outer surface of the annular inner cover 110. A second protrusion 151 is provided on the side of the spring clip 150 facing away from the center of the annular inner cover 110, for contacting the inner wall of the watch case 300 and supporting the lower surface of the inner support portion of the watch case 300. The lower surface of the elastic legs 160 is configured to contact the upper surface of the inner support portion of the watch case 300. In other words, the number of spring clips 150 and elastic legs 160 is the same, and each spring clip 150 and its corresponding elastic leg 160 jointly clamp the upper and lower surfaces of the same portion of the watch case 300, thereby ensuring the stability of the clamping between the watch shockproof structure 100 and the watch case 300. The second raised portion 151 on the spring clip 150 is used to limit the watch case 300 in the radial direction (the thickness direction of the watch case 300). The elastic leg 160 and the second raised portion 151 also jointly clamp the support on the inner wall of the watch case 300 to limit the watch case 300 in the axial direction (the height direction of the watch case 300). In addition, the spring clip 150 is used to cushion the watch from radial impacts, while the elastic leg 160 is used to cushion the watch from axial impacts, thereby providing shock absorption protection for the movement 200.

[0026] In one embodiment, a safety zone is formed between each spring clip 150 and its corresponding elastic leg 160. The annular inner cover 110 is provided with a plurality of through-holes 111 extending through the upper and lower surfaces of the annular inner cover 110 and corresponding to each safety zone. The spring clips 150 and the elastic legs 160 are located on opposite sides of the through-holes 111. The provision of through-holes 111 between the spring clips 150 and the elastic legs 160 not only reduces the weight of the annular inner cover 110 but also provides a safety zone for the spring clips 150 during deformation. Furthermore, four through-holes 111 are evenly spaced apart on the annular inner cover 110. Accordingly, four spring clips 150 and four elastic legs 160 are evenly spaced apart on the lower surface of the annular inner cover 110. In other embodiments, the number of through-holes 111, spring clips 150, and elastic legs 160 can be further increased or decreased based on actual needs. This will not be further described here.

[0027] In one embodiment, a curved reinforcement plate 112 is provided on the lower end surface of the annular inner cover 110, corresponding to the first boss 120. The surface of the first boss 120 facing away from the center of the annular inner cover 110 is fixedly connected to the surface of the curved reinforcement plate 112 adjacent to the center of the annular inner cover 110. The provision of the curved reinforcement plate 112 enhances the strength of the first boss 120, preventing the first boss 120 from breaking due to excessive pressure when it abuts the side surface of the movement 200. This extends the service life of the watch's shockproof structure 100 and ensures its reliability. Furthermore, in this embodiment, the width of the arc-shaped reinforcement plate 112 (i.e., the arc length of the arc-shaped reinforcement plate 112) is greater than the width of the first boss 120, and the height of the arc-shaped reinforcement plate 112 is greater than or equal to the height of the first boss 120. The annular inner cover 110, the arc-shaped reinforcement plate 112 and the first boss 120 are integrally formed. By making the width of the arc-shaped reinforcement plate 112 greater than the width of the first boss 120, the area of ​​the connection between the first boss 120 and the annular inner cover 110 is increased, and the stability of the first boss 120 installed on the annular inner cover 110 is improved; by making the height of the arc-shaped reinforcement plate 112 greater than or equal to the height of the first boss 120, the arc-shaped reinforcement plate 112 can fully support the first boss 120, so as to avoid the problem of breakage due to excessive shear force on the protruding part when the part protrudes from the arc-shaped reinforcement plate 112 on the first boss 120, thereby extending the service life of the watch shockproof structure 100. Preferably, the first boss 120 is fixedly connected to the middle portion of the arc-shaped reinforcement plate 112 adjacent to the center of the annular inner cover 110 to improve the reliability of the arc-shaped reinforcement plate 112 supporting the first boss 120 when the first boss 120 abuts against the side surface of the movement 200.

[0028] In one embodiment, the distance between the side surface of the spring clip 150 facing away from the center of the annular inner cover 110 and the inner wall of the watch case 300 is less than the thickness of the second protrusion 151. Thus, when the second protrusion 151 of the spring clip 150 abuts the inner wall of the watch case 300, because the distance between the spring clip 150 and the inner wall of the watch case 300 is less than the thickness of the second protrusion 151, the bottom end of the spring clip 150 deflects toward the center of the annular inner cover 110 and deforms, causing the second protrusion 151 to press against the inner wall of the watch case 300. While the second protrusion 151 supports the lower surface of the inner support of the watch case 300, it also presses against the inner wall of the watch case 300, thereby achieving bidirectional axial and radial positional limitation of the watch case 300. Furthermore, the width of the second protrusion 151 is smaller than the width of the spring clip 150, and the height of the second protrusion 151 is smaller than the height of the spring clip 150. By making the width of the second protrusion 151 smaller than the width of the spring clip 150 and the height of the second protrusion 151 smaller than the height of the spring clip 150, the effect of the oversized second protrusion 151 on the elasticity of the spring clip 150 can be reduced, ensuring that the spring clip 150 has sufficient elasticity to cushion radial impacts on the watch. Further preferably, the lower surface of the second protrusion 151 is flush with the lower surface of the spring clip 150. In this way, when the second protrusion 151 abuts the inner wall of the watch case 300, the torque applied to the connection between the spring clip 150 and the annular inner cover 110 is greater, and the spring clip 150 is more easily bent and deformed to provide cushioning against radial impacts on the watch.

[0029] In one embodiment, the elastic leg 160 is an elastic sheet protruding from the lower end surface of the annular inner cover 110. This elastic sheet deforms when pressed against the upper surface of the support portion within the watch case 300, thereby compressing the upper surface of the support portion within the watch case 300 and simultaneously cushioning the watch from axial impact. Furthermore, the upper end surface of the annular inner cover 110 has a plurality of notches 113 formed on the side of each through-hole 111 facing away from the center of the annular inner cover 110, correspondingly extending through each through-hole 111 and the outer surface of the annular inner cover 110. These notches 113 are located above the elastic leg 160. That is to say, the thickness of the portion of the annular inner cover 110 where the elastic bow foot 160 is located is thinner than the thickness of the other portions of the annular inner cover 110. Thus, by thinning the mounting portion of the elastic bow foot 160, when the elastic bow foot 160 is squeezed by the upper surface of the support inside the watch case 300, the mounting portion of the elastic bow foot 160 on the annular inner cover 110 will also be deformed, thereby further enhancing the elasticity of the elastic bow foot 160.

[0030] Please combine again Figure 1-4The utility model also discloses a watch head 10, which includes the above-mentioned watch shockproof structure 100. In addition, the watch head 10 also includes a movement 200 accommodated in the inner space of the annular inner cover 110, a watch case 300 sleeved on the outside of the annular inner cover 110, an annular bottom cover 400 located below the watch case 300 and sealed with the watch case 300, a back cover 500 embedded in the annular bottom cover 400 and sealed with the annular bottom cover 400, a dial 600 located above the movement 200 and abutting against the upper surfaces of the movement 200 and the annular inner cover 110 respectively, a front ring 700 clamped between the dial 600 and the watch case 300, a watch glass 800 located above the dial 600 and sealed with the front ring 700, and a handle passing through the side wall of the watch case 300 and connected to the movement 200. During the assembly of the watch head 10, the movement 200 is first inserted into the inner space of the annular inner cover 110, with the side surface of the movement 200 abutting against the first boss 120, the second boss 130 abutting against the upper surface of the movement 200, and the first protrusion 141 on the buckle 140 abutting against the support portion of the movement 200 plate, thereby completing the assembly of the movement 200 and the watch shockproof structure 100. The assembled movement 200 and watch shockproof structure 100 are then installed into the watch case 300, with the elastic legs 160 abutting against the upper surface of the support portion within the watch case 300, the second protrusion 151 abutting against the lower surface of the support portion within the watch case 300, and the second protrusion 151 abutting against the inner wall of the watch case 300, thus completing the shock-absorbing installation of the movement 200 on the watch case 300. Finally, install the annular bottom cover 400, back cover 500, dial 600, front ring 700, watch glass 800 and crown on the watch case 300 respectively.

[0031] The utility model also discloses a watch comprising the aforementioned shockproof structure 100. The watch also includes a movement 200 housed within an annular inner cover 110, a watch case 300 sleeved outside the annular inner cover 110, an annular bottom cover 400 positioned below and sealed to the watch case 300, a back cover 500 embedded within and sealingly engaged with the annular bottom cover 400, a dial 600 positioned above the movement 200 and abutting the upper surfaces of the movement 200 and the annular inner cover 110, a front bezel 700 engaged between the dial 600 and the watch case 300, a watch glass 800 positioned above the dial 600 and sealed to the front bezel 700, and a crown extending through the sidewall of the watch case 300 and connected to the movement 200. In other words, the watch also includes the aforementioned watch head 10. Furthermore, the watch also includes a strap or bracelet secured to the watch case 300 for consumers to wear the watch.

[0032] When the watch is subjected to an axial impact, the second boss 130 and the buckle 140 jointly secure the movement 200, preventing it from shifting within the annular inner cover 110 and potentially affecting the movement of the dial 600 and hands. Simultaneously, the elastic legs 160 on the outer periphery of the annular inner cover 110 absorb the impact energy through elastic deformation, thus cushioning the watch from axial impact. When the watch is subjected to a radial impact, the movement 200 and the annular inner cover 110 are relatively fixed, and the elastic design of the spring clip 150 also provides a certain degree of cushioning against the impact force, effectively buffering the watch from radial impact. In summary, the second boss 130 and the buckle 140 secure the movement 200 and the annular inner cover 110 internally, preventing radial or axial displacement of the movement 200. On the outside, the elastic legs 160 and the spring clip 150 cushion and absorb radial and axial impact forces, achieving shockproofing.

[0033] The above-mentioned watch shockproof structure 100, watch head 10 and watch, through the first boss 120, press the movement 200 to limit the radial displacement of the movement 200, through the second boss 130 and the buckle 140, clamp the movement 200 to limit the axial displacement of the movement 200, through the elastic bow foot 160 and the second protrusion 151 to clamp the case 300 to limit the axial displacement of the case 300, and through the contact between the second protrusion 151 and the inner wall of the case 300, limit the radial displacement of the case 300. In this way, the movement 200 and the case 300 can be installed through a single annular inner cover 110 and various components fixed on the annular inner cover 110; when the watch is subjected to axial impact, the movement 200 can be prevented from being moved in the annular inner cover. The movement of the cover 110 causes the malfunction of the dial 600 and the hands to be caused, and the elastic bow foot 160 can absorb part of the impact energy to reduce the overall vibration of the watch; when the watch is subjected to radial impact, the shrapnel 150 can cushion the radial impact, and the shockproof structure 100 of the watch can avoid radial or axial displacement of the movement 200 while cushioning and absorbing the radial and axial impact forces, and has good shockproof effect. The connection between the movement 200 and the annular inner cover 110 is not easy to loosen, and the structure is stable. The movement 200 is inserted into the inner space of the annular inner cover 110, and the annular inner cover 110 is inserted into the support position of the case 300, so that the movement 200 can be installed on the case 300, reducing the difficulty of assembling the movement 200.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
