[0001] The invention relates to the technical field of watch structures, in particular to a thin watch shockproof structure. Background Art

[0002] In the process of wearing a watch, in order to adapt to different life scenes and sports behaviors of users, the watch is often required to have excellent shockproof function to avoid the failure of the hands to rotate or even the failure of the watch due to the shock of the movement, so as to ensure the reliable use of the watch. Specifically, for the structure of the watch itself, the components of a normally working watch are precisely matched, and the performance of the watch is closely related to its assembly reliability. If the shockproof ability of the watch is weak, it is easy for the indicator components and movement components of the watch to loosen and shift due to vibration during daily use, affecting the function of the watch.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] See also Figure 1The present invention provides a thin watch shockproof structure 10 that takes into account both the thickness and shockproof performance of the watch. The thin watch shockproof structure 10 includes a watch case 100, a front ring 200 provided at the top of the watch case 100 and interference-fitted with the watch case 100, and a back cover 300 provided at the bottom of the watch case 100. The watch case 100, the front ring 200, and the back cover 300 together form an inner watch space 400, and the inner watch space 400 accommodates a movement 500. The thin watch shockproof structure 10 also includes a shock-absorbing member 600 provided between the movement 500 and the watch case 100, that is, the shock-absorbing member 600 only occupies the radial width between the movement 500 and the watch case 100 to fully utilize the inner watch space 400 of the thin watch, so as to reduce the influence of the shock-absorbing member 600 on the thickness of the thin watch. It should be noted that, in this embodiment, the radial direction of the movement 500 refers to the direction along the middle of the movement 500 pointing to the edge of the movement 500, the axial direction refers to the thickness direction of the thin watch, and the circumferential direction refers to the circumferential direction centered on the middle of the movement 500. This explanation may be referred to in other embodiments.

[0023] The shock absorber 600 includes a lower inner cover 610 and an upper inner cover 620, which are respectively made of elastic materials and are clamped with each other. Preferably, the lower inner cover 610 and the upper inner cover 620 are respectively made of amorphous alloys, which can be one of zirconium-based amorphous alloys, iron-based amorphous alloys, copper-based amorphous alloys, titanium-based amorphous alloys and palladium-based amorphous alloys. The elastic limit of the above-mentioned amorphous alloys can reach 1.5% to 2.8%, the hardness can reach 430 to 700 HV, and the yield strength is greater than 1000 MPa. In this way, during the processing of the shock absorber 600, while ensuring the elastic performance of the components, the thickness of the lower inner cover 610 and the upper inner cover 620 can be controlled at the millimeter level, thereby reducing the size of the shock absorber 600 to reduce the difficulty of installing the shock absorber 600 and make full use of the inner space 400 of the thin watch.

[0024] Please combine Figure 2 and Figure 3 A first convex position 611 is provided at the bottom of the lower inner cover 610, and the first convex position 611 is axially abutted with the back cover 300 to form a first shock-absorbing zone. The inner wall of the lower inner cover 610 contacts the outer wall of the movement 500 to form a first contact zone. A second convex position 621 is provided on the outer wall of the upper inner cover 620, and the second convex position 621 contacts the inner wall of the watch case 100 to form a second shock-absorbing zone. The inner wall of the upper inner cover 620 contacts the outer wall of the movement 500 to form a second contact zone. The first shock-absorbing zone is used to provide axial shock-proof protection for the movement 500, and the second shock-absorbing zone is used to provide radial shock-proof protection for the movement 500. The first contact zone and the second contact zone are used to flexibly cover the movement 500 and provide shock-absorbing protection for the movement 500.

[0025] Specifically, when the back cover 300 is subjected to an external impact, the mechanical energy generated by the impact will be transferred to the lower inner cover 610 via the first convex position 611, and stored in the lower inner cover 610 in the form of elastic potential energy. In this case, since the inner wall of the lower inner cover 610 covers the outer wall of the movement 500, the deformation at the inner wall of the lower inner cover 610 is extremely small, and the potential energy transferred from the inner wall of the lower inner cover 610 to the movement 500 is extremely small, thereby achieving axial shock protection for the movement 500. Similarly, when the watch case 100 is subjected to an external impact, the watch case 100 transfers the mechanical energy generated by the impact to the upper inner cover 620 via the second convex position 621, and stores it in the upper inner cover 620 in the form of elastic potential energy. Moreover, since the inner wall of the upper inner cover 620 covers the outer wall of the movement 500, the elastic potential energy transferred from the second convex position 621 to the inner wall of the upper inner cover 620 is extremely small. Thus, the potential energy transferred from the inner wall of the upper inner cover 620 to the movement 500 is extremely small, thereby achieving radial shockproof protection for the movement 500.

[0026] See also Figure 3 In one embodiment, the top surface of the upper inner cover 620 protrudes toward the center of the upper inner cover 620 to form a third convex position 622, and the bottom surface of the third convex position 622 abuts against the movement 500 to limit the axial displacement of the movement 500 and provide axial shock absorption protection for the movement 500. Preferably, the bottom surface of the third convex position 622 is a plane, so that the contact area between the third convex position 622 and the movement 500 is increased, thereby improving the stability of the connection between the two. Furthermore, a dial 700 is provided on the top of the upper inner cover 620 and is limited by the front ring 200. In this way, the upper inner cover 620 and the lower inner cover 610 are respectively tightly matched with the movement 500 under the common limitation of the dial 700 and the back cover 300, so as to cover the movement 500 and limit the movement 500, thereby preventing the movement 500 from vibrating and shaking due to impact caused by a gap at the connection between the movement 500 and the shock absorber 600, thereby improving the shockproof performance of the thin watch.

[0027] It should be noted that, in one embodiment, the cross sections of the first convex position 611, the second convex position 621, and the third convex position 622 are arc-shaped or wavy structures. By setting the cross sections of the first convex position 611, the second convex position 621, and the third convex position 622 to be arc-shaped or wavy structures, while facilitating the positioning of the upper inner cover 620 and the lower inner cover 610, the material usage of the upper inner cover 620 and the lower inner cover 610 is reduced, thereby reducing the production cost and overall weight of the thin watch.

[0028] Please combine Figure 2 and Figure 3In one embodiment, the number of the first convex position 611, the second convex position 621 and the third convex position 622 are respectively more than three, each first convex position 611 is evenly arranged at the bottom of the lower inner cover 610 along the circumferential direction, each second convex position 621 is evenly arranged at the outer wall of the upper inner cover 620 along the circumferential direction, and each third convex position 622 is evenly arranged at the top of the inner wall of the upper inner cover 620 along the circumferential direction. By evenly arranging a plurality of first convex positions 611 and third convex positions 622 on the upper inner cover 620 and evenly arranging a plurality of second convex positions 621 on the lower inner cover 610, the force balance of the connection body formed by the upper inner cover 620, the watch case 100 and the movement 500 is ensured, and the force balance of the connection body formed when the lower inner cover 610 contacts the back cover 300 is ensured, that is, the stability of the coordination of the various components in the inner space 400 of the thin watch is improved, which is conducive to improving the performance of the thin watch.

[0029] Furthermore, in one embodiment, a plurality of first hollow avoidance portions 612 extending radially and corresponding one to one to the first convex positions 611 are uniformly provided on the circumference of the lower inner cover 610, and a plurality of second hollow avoidance portions 623 extending axially and corresponding one to one to the second convex positions 621 are uniformly provided on the circumference of the upper inner cover 620. In this way, after the thin watch is assembled, when any component in the back cover 300 or the watch case 100 is subjected to an external impact force, the mechanical energy generated by the external impact will be transmitted to the lower inner cover 610 via the first convex position 611 or to the upper inner cover 620 via the second convex position 621, and in this process, the area around the first convex position 611 or the area around the second convex position 621 will produce elastic deformation, and the deformed area can be squeezed toward the first hollow avoidance portion 612 or the second hollow avoidance portion 623. In other words, the second convex position 621 is formed on the upper inner cover 620. The provision of a hollow avoidance portion 612 and a second hollow avoidance portion 623 increases the elastic deformation capacity of the lower inner cover 610 and the upper inner cover 620. The first protrusion 611 is compressed when squeezed by the back cover 300, thereby achieving flexible cooperation between the lower inner cover 610 and the back cover 300. Similarly, the second protrusion 621 is compressed when squeezed by the watch case 100, thereby achieving flexible cooperation between the upper inner cover 620 and the watch case 100. While achieving shockproof and shock-absorbing protection, the stability of the connection of various components in the inner space 400 of the watch is improved.

[0030] Please combine Figure 3 and Figure 4In one embodiment, a first truncated cone 624 and a second truncated cone 625 which is concentrically arranged with the first truncated cone 624 and arranged at the outer edge of the first truncated cone 624 are provided at the bottom of the upper inner cover 620. The height of the first truncated cone 624 is less than the height of the second truncated cone 625. The third protrusion 622 is provided on the inner wall of the first truncated cone 624, and the bottom surface of the first truncated cone 624 cooperates with the top surface of the lower inner cover 610. Furthermore, in one embodiment, a limiting notch 626 is provided on the second truncated cone 625, which passes through the top of the second truncated cone 625 and extends to the bottom, and has a depth less than the height of the second truncated cone 625, and a guide notch 627 is provided on the second truncated cone 625, which passes through the bottom of the second truncated cone 625 and extends to the top, and has a depth less than the height of the second truncated cone 625. The limiting notch 626 is connected to the guide notch 627, and the limiting notch 626 is connected to the bottom space of the first truncated cone 624 to pass through the inner and outer sides of the upper inner cover 620. A block 613 is provided on the outer wall of the lower inner cover 610, which enters the limiting notch 626 through the guide notch 627 and cooperates with the limiting notch 626 to limit the position. It can be understood that the limiting notch 626 and the guide notch 627 together constitute a bayonet for limiting the position of the block 613. In one embodiment, a plurality of bayonet holes are evenly arranged on the second truncated cone 625, and the number of the block 613 corresponds to the bayonet holes one by one. In this way, during the assembly and combination of the lower inner cover 610 and the upper inner cover 620, it is only necessary to embed the block 613 on the lower inner cover 610 into the corresponding guide notch 627 one by one. When the position of the block 613 in the guide notch 627 is flush with the connecting portion between the guide notch 627 and the limiting notch 626, the lower inner cover 610 is rotated relative to the upper inner cover 620 until the block 613 enters the limiting notch 626. In this way, the block 613 is difficult to shake relative to the upper inner cover 620 under the constraint of the inner wall of the limiting notch 626, thereby realizing the axial positioning of the lower inner cover 610 and the upper inner cover 620.

[0031] It should be further explained that, in one embodiment, the depth of the guide notch 627 and the height difference of the second truncated cone 625 are equal to or less than the height of the first truncated cone 624. It can be understood that the inner top surface of the guide notch 627 is flush with or higher than the bottom surface of the second truncated cone 625, so as to avoid the problem that the block 613 is difficult to pass due to the too narrow communication part between the guide notch 627 and the limiting notch 626, thereby reducing the difficulty of assembling and disassembling the lower inner cover 610 and the upper inner cover 620.

[0032] Please refer again Figure 3In one embodiment, the upper inner cover 620 is provided with an avoidance hole 628 which passes through the top of the upper inner cover 620 and is respectively connected with the guide notch 627 and the limit notch 626. A spring piece 629 which can swing relative to the avoidance hole 628 and is partially tilted and embedded in the avoidance hole 628 is formed on the outer wall of the upper inner cover 620 at a position corresponding to the avoidance hole 628. The spring piece 629 has a second convex position 621 on its outer side wall. In this way, when the watch case 100 is subjected to external shock or impact, the second protrusion 621 on the spring piece 629 is squeezed by the watch case 100 and transmits the force to the spring piece 629, so that the spring piece 629 is bent by the force and embedded in the avoidance hole 628. In this way, the mechanical energy generated when the watch case 100 is vibrated is transmitted to the spring piece 629 via the second protrusion 621 and converted into the elastic potential energy of the spring piece 629, thereby avoiding or reducing the deformation of the inner wall of the upper inner cover 620, so as to achieve the shockproof or shock-absorbing effect on the movement 500.

[0033] The thin watch shockproof structure 10 of the present invention is implemented, and a shock absorbing member 600 consisting of a lower inner cover 610 and an upper inner cover 620 is arranged between the movement 500 and the watch case 100. The shock absorbing member 600 is made of elastic material, and abuts with the back cover 300 through a first convex position 611 arranged on the lower inner cover 610 to buffer the axial impact force received by the movement 500 and the back cover 300, and abuts with the watch case 100 through a second convex position 621 arranged on the upper inner cover 620 to buffer the radial impact force received by the movement 500 and the watch case 100, and the inner wall of the lower case and The inner walls of the upper shell are respectively covered and contacted with the outer wall of the movement 500, thereby realizing shockproof protection for the movement 500. The shock-absorbing component 600 only occupies the radial width between the movement 500 and the watch case 100, does not affect the thickness of the thin watch, and makes full use of the inner space 400 of the thin watch. In this way, it is only necessary to set a reserved position for the shock-absorbing component 600 between the movement 500 and the watch case 100 so that the shock-absorbing component 600 can be installed in the thin watch, which takes into account the thickness and shockproof performance of the watch, reduces the difficulty of installing the shock-absorbing component 600, and is conducive to improving the market competitiveness of thin watches.

[0035] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
