Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of watches, in particular to a watch head shockproof structure and a watch. Background Art
[0002] Affected by the user's daily activities, the vibrations and shocks generated during the activities will inevitably be transmitted to the watch worn by the user. If there is a lack of effective shockproof measures in the watch, the parts inside the watch will become loose, misaligned, or even damaged. Secondly, the watch may accidentally collide with hard objects during wearing, and the strong impact force may easily damage the watch. In addition, for mechanical watches with high-precision movements, even tiny vibrations may affect the accuracy and stability of their travel time. In some special environments, such as construction sites and intense sports venues, the watch is subjected to greater vibration and impact intensity. Therefore, designing a shockproof structure on the watch is of great significance to ensure the normal operation of the watch and extend its service life.
[0003] At present, the shockproof methods of watches mainly include the shockproof design of the movement itself and the shockproof protection of the entire movement through the inner cover. Among them, the shockproof of the inner cover is the mainstream measure for shockproofing of watches. The common shock-absorbing inner covers in the industry include plastic inner covers and metal inner covers. The plastic inner cover is shockproof by designing elastic convex rice, while the metal inner cover absorbs the energy impact generated by vibration by setting rubber rings. Since the impact direction of the watch is random in daily activities, the metal inner cover with rubber rings can buffer the impact in all directions, but the metal inner cover itself will increase the weight of the watch, thereby affecting the wearing experience of the watch; the use of metal inner covers will increase the processing cost of the watch; in addition, when using metal inner covers, the movement needs to be fixed by fixing screws and fixing plates, which makes the assembly process of the watch more cumbersome. Therefore, the industry mainly uses plastic inner covers to reduce shock for watches. However, since the plastic inner cover protects the movement by adding elastic convexities, in order to ensure that the movement does not loosen in the watch case, the number of elastic convexities designed on the side of the plastic inner cover is very limited. When there are no elastic convexities in the direction of impact on the watch, the shockproof performance of the side of the watch is poor, making the overall shockproof effect of the plastic inner cover relatively insufficient.

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model 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 utility model. However, the utility model 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 utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0024] Please combine Figure 1-3 The utility model discloses a shockproof structure for a meter head that is light in weight, low in processing cost, easy to assemble and has good shockproof effect. The shockproof structure for the meter head includes an upper annular plastic inner cover 100 and a lower annular plastic inner cover 200, wherein the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are both made of plastic materials to reduce the weight of the entire shockproof structure for the meter head and reduce its processing cost. In this embodiment, the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 can be made of one of the materials such as PC, PE, PP and PMMA. In this way, while reducing the weight of the shockproof structure for the meter head, the mechanical strength of the entire shockproof structure for the meter head is guaranteed, and the selection of plastic materials gives the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 a certain elasticity so as to buffer the impact force acting on the movement.
[0025] For details, please combine Figure 1-5 In this embodiment, the inner space of the upper annular plastic inner cover 100 forms an installation area 110 for accommodating the movement. The upper surface of the upper annular plastic inner cover 100 is provided with a limit plate 120 that protrudes toward the installation area 110 and is used to abut against the upper surface of the movement splint. That is, the lower surface of the limit plate 120 abuts against the upper surface of the movement splint to limit the top of the movement. The inner ring surface of the upper annular plastic inner cover 100 is provided with a boss 130 for abutting against the side of the movement. The boss 130 is used to position the side of the movement to limit the position of the movement along the radial direction of the movement and prevent the movement from shaking in the installation area 110.
[0026] The lower annular plastic inner cover 200 is sleeved on the periphery of the upper annular plastic inner cover 100 and is snap-connected with the upper annular plastic inner cover 100. In other words, the upper annular plastic inner cover 100 is accommodated in the inner ring space of the lower annular plastic inner cover 200. The inner ring surface of the lower annular plastic inner cover 200 fits with the outer ring surface of the upper annular plastic inner cover 100, so that the radial position of the upper annular plastic inner cover 100 is limited by the abutment between the inner ring surface of the lower annular plastic inner cover 200 and the outer ring surface of the upper annular plastic inner cover 100, so as to prevent the upper annular plastic inner cover 100 from shaking in the inner cavity of the lower annular plastic inner cover 200. The inner ring surface of the lower annular plastic inner cover 200 is provided with a plurality of support blocks 210 arranged at intervals along the circumferential direction of the lower annular plastic inner cover 200; the support block 210 is provided with a first step 211 for receiving the upper annular plastic inner cover 100, a second step 212 located below the side of the first step 211 and used to receive the movement, and an elastic cover foot 213 located at the bottom of the support block 210 and used to elastically abut against the back cover of the watch, that is, the plurality of support blocks 210 are used together to support the upper annular plastic inner cover 100 and the movement located in the installation area 110 of the upper annular plastic inner cover. In this embodiment, the second step 212 is used to support the bottom of the movement, so that the movement is limited along the axial direction of the movement by the cooperation of the second step 212 and the limiting plate 120. The upper annular plastic inner cover 100 is supported by the first step 211 and the upper annular plastic inner cover 100 is connected with the lower annular plastic inner cover 200 by a snap connection, so that the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are connected together to improve the stability of the overall structure of the shockproof structure of the watch head. The elastic contact between the elastic cover foot 213 and the back cover of the watch can buffer the impact force along the axial direction of the movement. The outer ring surface of the lower annular plastic inner cover 200 is provided with a plurality of elastic spokes 220 arranged at intervals along the circumferential direction of the lower annular plastic inner cover 200, and the ends of the elastic spokes 220 are abutted against the inner wall of the watch case. The angle between the tangent direction of the connection between the elastic spokes 220 and the lower annular plastic inner cover 200 and the extension direction of the elastic spokes 220 is α, and α is less than 90°. It can also be understood that the elastic spokes 220 are tiltedly arranged on the outer surface of the lower annular plastic inner cover 200. Since the lower annular plastic inner cover 200 is made of plastic material, when the ends of the elastic spokes 220 are impacted by the inner wall of the watch case, the elastic spokes 220 will produce a certain elastic deformation, thereby buffering the radial impact on the watch. In this way, through the cooperation of the elastic cover feet 213 and the elastic spokes 220, all-round protection of the movement can be achieved.
[0027] In this solution, the buckle connection between the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 includes at least two alternative forms. Specifically, in one embodiment, the lower surface of the upper annular plastic inner cover 100 is provided with an elastic hook, and the side of the elastic hook facing away from the installation area 110 is provided with a protrusion for abutting against the lower surface of the lower annular plastic inner cover 200. In this way, in the process of the upper annular plastic inner cover 100 being embedded into the inner cavity of the lower annular plastic inner cover 200 from top to bottom, the raised portion on the elastic hook first abuts against the inner ring surface of the lower annular plastic inner cover 200, and moves toward the direction close to the installation area 110 under the extrusion of the inner ring surface of the lower annular plastic inner cover 200, so that the elastic hook bends toward the direction close to the installation area 110 to deform, until the lower surface of the upper annular plastic inner cover 100 abuts against the first step 211. At this time, the constraint of the inner ring surface of the lower annular plastic inner cover 200 on the raised portion is released, and the elastic hook restores the elastic deformation, and makes the upper surface of the raised portion abut against the lower surface of the lower annular plastic inner cover 200, thereby realizing the limited connection of the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 along the axial direction of the movement. In another embodiment, an extension arm 140 is provided on the lower surface of the upper annular plastic inner cover 100, and a clamping portion 141 protruding in the direction away from the installation area 110 is provided at the bottom of the extension arm 140; a notch 230 is provided on the inner ring surface of the lower annular plastic inner cover 200, which passes through the upper and lower surfaces of the lower annular plastic inner cover 200 and is used to correspond to the clamping portion 141. Further preferably, a rotation avoidance area 240 is provided on the inner ring surface of the lower annular plastic inner cover 200 between the notch 230 and the support block 210, that is, the notch 230 and the support block 210 are spaced apart, and a locking adjustment area is reserved between the two for the upper annular plastic inner cover 100 to rotate relative to the lower annular plastic inner cover 200. In this way, when the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are assembled, the clamping portion 141 at the end of the extension arm 140 is first aligned. The notch 230 on the lower annular plastic inner cover 200 is aligned, and the upper annular plastic inner cover 100 is pushed downward until the lower surface of the upper annular plastic inner cover 100 abuts against the first step 211, and then the upper annular plastic inner cover 100 is rotated so that the clamping portion 141 rotates with the extension arm 140 and leaves the notch 230 until the clamping portion 141 abuts against the lower surface of the lower annular plastic inner cover 200, that is, the axial fixation between the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 is achieved. In addition, it should be noted that in the above two embodiments, the elastic hook and the extension arm 140 both have a certain elasticity, which can be used to buffer the axial impact on the watch.
[0028] In one embodiment, the elastic cover foot 213 is fixed to the bottom of the support block 210, and the elastic cover foot 213 is deformed when it is squeezed by the back cover of the watch. That is to say, when the elastic cover foot 213 abuts against the back cover of the watch, the axial impact from the back cover of the watch is buffered by the deformation of the elastic cover foot 213 itself. In this embodiment, the elastic cover foot 213 is a spring with one end fixed to the bottom of the support block 210 and the other end abutting against the back cover of the watch. According to different processing techniques, the spring can be a compression spring or a special-shaped spring or a spring structure processed into a wavy structure. In another embodiment, a through hole 250 is provided on the support block 210, which passes through two opposite sides of the support block 210 and is located above the elastic cover foot 213; the connection part of the support block 210 with the elastic cover foot 213 is deformed when the elastic cover foot 213 is squeezed by the back cover of the watch, so as to drive the elastic cover foot 213 to move. In the present embodiment, by opening a through hole 250 above the elastic cover foot 213, the material of the portion on the support block 210 where the elastic cover foot 213 is installed is reduced, making this portion more susceptible to deformation. In this way, when the elastic cover foot 213 is subjected to the impact force of the watch back cover, the elastic cover foot 213 itself does not deform, but transfers the force to the portion on the support block 210 where the elastic cover foot 213 is installed, causing this portion to deform and drive the elastic cover foot 213 to move, thereby achieving buffering of the axial impact on the watch back cover.
[0029] In this embodiment, by providing elastic cover feet 213 at the bottom of each support block 210, multi-point contact between the lower annular plastic inner cover 200 and the back cover of the mobile phone can be achieved. Furthermore, multiple elastic cover feet 213 are evenly arranged along the circumferential direction of the lower annular plastic inner cover 200, so that the force on the lower annular plastic inner cover 200 is stable. When the watch is subjected to axial impact, the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 clamp the movement together, which can prevent the movement from shifting in the axial direction. In addition, the elastic hook (or extension arm 140) and the elastic cover feet 213 have a certain elasticity, which can absorb energy when subjected to axial impact to play a shockproof role.
[0030] In one embodiment, a plurality of stop plates 120 are evenly spaced on the upper surface of the upper annular plastic inner cover 100. Preferably, three stop plates 120 are evenly spaced on the upper surface of the upper annular plastic inner cover 100 so that the upper surface of the movement splint is evenly stressed. Further, the thickness of the stop plate 120 is less than the height of the upper annular plastic inner cover 100 so that an installation area 110 for the upper annular plastic inner cover 100 and the movement is reserved between the stop plate 120 and the second step 212. In addition, the top of the boss 130 is flush with the upper surface of the upper annular plastic inner cover 100, and the bottom of the boss 130 is flush with the lower surface of the upper annular plastic inner cover 100. The side of the boss 130 located in the installation area 110 is a convex arc surface. When the outer side surface of the movement contacts the boss 130, there is actually a line contact between the movement and the boss 130. It replaces the surface contact method for positioning the movement, which can avoid scratches on the outer ring surface of the movement or loose positioning due to the uneven surface of the contact surface. While ensuring the stable positioning of the movement, it reduces the processing difficulty of the boss 130.
[0031] In one embodiment, the outer ring surface of the lower annular plastic inner cover 200 is provided with 6 elastic spokes 220 evenly spaced along the circumferential direction of the lower annular plastic inner cover 200. Of course, the number of the elastic spokes 220 can be greater than 1. Since the extension direction of the elastic spokes 220 is arranged at a certain angle to the inner wall of the case and the movement, when the watch is subjected to radial impact at different angles, 2-3 spokes will always be deformed to a certain extent to absorb the energy generated by the impact, thereby achieving radial shock absorption and buffering of the movement.
[0032] In this solution, when assembling the watch head, first, the movement is embedded into the installation area 110 of the upper annular plastic inner cover 100 from bottom to top, so that the boss 130 abuts against the side of the movement, and the upper surface of the movement clamp abuts against the lower surface of the limit plate 120. Then, the clamping part 141 at the end of the extension arm 140 is aligned with the notch 230 on the lower annular plastic inner cover 200, and the upper annular plastic inner cover 100 is pushed downward until the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are fitted, and the lower annular plastic inner cover 200 is rotated so that the clamping part 141 abuts against the lower surface of the lower annular plastic inner cover 200 to prevent the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 from being disengaged, and the assembly of the shockproof structure of the watch head is completed. Then, the assembled movement and the shockproof structure of the watch head are installed into the watch case. At this time, the lower annular plastic inner cover 200 supports the movement, the elastic cover feet 213 abut against the back cover of the watch, and the elastic spokes 220 abut against the inner wall of the watch case to fix the shockproof structure of the watch head. At this time, the movement is fixed in the shockproof structure of the watch head and the watch case through the snap connection between the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 and the abutment between the boss 130 and the movement.
[0033] The above-mentioned shockproof structure of the watch head can protect the watch from impacts at all angles by arranging elastic spokes 220 on the outer surface of the lower annular plastic inner cover 200; the conventional upper and lower inner cover structures mainly adopt the method of assembling the movement from top to bottom, and the upper and lower inner covers need to be assembled separately during assembly. The present solution adopts the method of assembling the movement from bottom to top, and there is no need to assemble the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 separately, so the assembly difficulty is low and the application range is wider.
[0034] In addition, the utility model also discloses a watch, which includes the above-mentioned watch head shockproof structure. The specific structure of the watch head shockproof structure is not repeated here. Furthermore, the watch also includes a movement 300 accommodated in the installation area 110 of the upper annular plastic inner cover 100, a case 400 covered on the outer periphery of the lower upper annular plastic inner cover 100, a dial 500 located above the movement 300 and limitedly abutted against the case 400, a watch glass 600 located above the dial 500 and sealedly connected to the case 400, and a watch back cover 700 located below the movement 300 and sealedly connected to the case 400. When the watch head shockproof structure is installed in the case 400, the elastic spokes 220 abut against the inner side of the case 400, and the elastic cover feet 21 3 elastically abuts against the watch back cover 700, the side of the movement 300 abuts against the boss 130, and the upper surface of the movement splint abuts against the limit plate 120. In this way, the movement 300 is limited by the joint constraint of the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200, and the elastic cover foot 213 elastically abuts against the watch back cover 700 to buffer the axial impact on the movement 300, and the elastic spokes 220 abut against the inner side of the watch case 400 to buffer the impact of radial angles on the movement 300, thereby achieving all-round shock absorption of the movement 300.
[0035] In the watch head shockproof structure and the watch of the utility model, the upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are both made of plastic material, which reduces the overall weight of the watch head shockproof structure and reduces the processing cost of the watch head shockproof structure; the overall structure is simple, and there is no need to use machine screws and machine plates to fix the movement. The movement can be fixed only by the limit plate 120 and the boss 130 on the upper annular plastic inner cover 100 and the second step 212 on the lower annular plastic inner cover 200, which reduces the difficulty of assembling the watch. ; The upper annular plastic inner cover 100 and the lower annular plastic inner cover 200 are used to clamp the movement together, so as to avoid axial displacement of the movement; the elastic cover feet 213 are provided to buffer the axial impact on the movement; the multiple inclined elastic spokes 220 on the outer ring surface of the lower annular plastic inner cover 200, when the watch is subjected to radial impacts at different angles, the elastic spokes 220 will always produce a certain degree of deformation to absorb the energy generated by the impact, thereby achieving all-round axial and radial protection for the movement and improving the shockproof effect of the watch.
[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
