Description
Technical Field
[0001] The utility model relates to the technical field of watches, in particular to a shockproof watch head and a watch. Background Art
[0002] Due to the complexity and diversity of watch usage scenarios, watches need to withstand shocks and vibrations from different directions, such as arm swings and collisions during exercise. These shocks and vibrations may damage components such as the movement, dial, and hands, thereby affecting the watch's accuracy and service life. Therefore, designing a shockproof structure in the watch has become an important part of watch design. Traditional watch structures usually fix the dial to the movement, and the dial is in rigid contact with the case and front bezel. The shockproof structure supports the movement while pressing the dial and bottom cover. This tight assembly method makes the watch's shock resistance poor. In addition, to ensure that the shockproof structure has sufficient buffering effect in both the axial and circumferential directions of the watch, certain requirements are placed on the thickness and other dimensions of the shockproof structure in all directions. The large size of the shockproof structure will occupy a large space inside the watch, thereby restricting the diversified design of the watch's appearance. Utility Model Content
[0003] Based on this, it is necessary to provide a shockproof watch head and a watch with good shockproof performance, compact shockproof component structure and reduced space occupied in the watch in order to address the above-mentioned shortcomings.
[0004] A shockproof watch head comprises a watch case, a front bezel with a sealing cover mounted on the upper surface of the watch case, a watch glass with a sealing cover mounted on the front bezel, a back cover with a sealing cover mounted on the lower surface of the watch case, a movement accommodated in the inner cavity of the watch case, a dial located between the movement and the watch glass, and a watch hand assembly located between the dial and the watch glass and connected to the movement. The shockproof watch head further comprises a shockproof component, which comprises:

[0006] The fixing spring piece includes a fixing portion connected to the inner wall screw of the watch case, and an elastic abutting portion fixedly connected to the fixing portion and elastically pressed onto a side of the third connecting portion adjacent to the dial.
[0007] In one embodiment, the movement cover and the fixing spring are both annular structures arranged around the movement.
[0008] In one embodiment, the shockproof component includes a plurality of fixed springs arranged around the movement and connected to the inner wall of the case with screws, and a plurality of movement covers elastically matched with each fixed spring and connected to the movement screws.
[0009] In one embodiment, the elastic abutment portion of the fixing spring is an annular structure, and a plurality of protrusions are arranged at intervals on the outer ring side of the elastic abutment portion to form the fixing portion.
[0010] In one embodiment, the angle between the first inclined surface and the axial direction of the movement is 30-60°, and the angle between the second inclined surface and the axial direction of the movement is 30-60°.
[0011] In one embodiment, the inner wall of the watch case protrudes toward the direction close to the movement to form a first step, the lower surface of the fixing portion abuts against the upper surface of the first step and is fixedly connected to the first step by a first screw; the second inclined surface is formed at the edge of the upper surface of the first step; a first through hole is provided on the fixing portion, a first screw hole is provided on the upper surface of the first step, and the first screw passes through the first through hole and is inserted into the first screw hole.
[0012] In one embodiment, a second step is formed on the side of the third connecting portion facing away from the movement at the far end of the first inclined surface, and the lower surface of the elastic abutting portion elastically abuts against the upper surface of the second step; the first connecting portion is fixedly connected to the upper surface of the movement by a second screw.
[0013] In one embodiment, a second through hole is formed on the first connecting portion, a second screw hole is formed on the upper surface of the movement, and the second screw passes through the second through hole and is inserted into the second screw hole.
[0014] In one embodiment, the distance between the dial and the movement is greater than 0, and the lower surface of the dial abuts against the first connecting portion.
[0015] The utility model also discloses a watch, which comprises the shockproof watch head.
[0016] The shockproof watch head and watch of the present invention are implemented by fixing the movement cover on the movement and installing a fixed spring piece on the inner wall of the watch case. The axial and radial positioning of the movement are achieved through the elastic cooperation between the fixed spring piece and the movement cover, and the abutment between the first inclined surface on the movement cover and the second inclined surface on the inner wall of the watch case.

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 1-5The utility model discloses a shockproof watch head with good shockproof performance, compact shockproof component structure and reduced space occupied in the watch. The shockproof watch head includes a watch case 100, a front bezel 200 with a sealing cover mounted on the upper surface of the watch case 100, a watch glass 300 with a sealing cover mounted on the front bezel 200, a back cover 400 with a sealing cover mounted on the lower surface of the watch case 100, a movement 500 accommodated in the inner cavity of the watch case 100, a dial 600 located between the movement 500 and the watch glass 300, and a watch hand assembly 700 located between the dial 600 and the watch glass 300 and drivingly connected to the movement 500. That is, sealing rings are provided at the mating parts of the front bezel 200 and the watch case 100, at the mating parts of the watch case 100 and the front bezel 200, and at the mating parts of the back cover 400 and the watch case 100 to ensure the waterproof performance of the shockproof watch head. In addition, the upper surface of the watch case 100 refers to the side of the watch case 100 facing the outside of the user's body when the watch is worn (i.e., the main surface of the watch case 100), the lower surface of the watch case 100 refers to the side of the watch case 100 facing the user's body when the watch is worn (i.e., the back of the watch case 100), the upper surfaces of the remaining components refer to the sides of the components located on the same side as the upper surface of the watch case 100, and the lower surfaces of the remaining components refer to the sides of the components located on the same side as the lower surface of the watch case 100, which will not be described in detail here. The hand assembly 700 includes an hour hand 710, a minute hand 720, and a second hand 730 located on one side of the main surface of the dial 600, an hour hand drive shaft 740 that penetrates the dial 600 and is used to drive the hour hand 710 to rotate, a minute hand drive shaft 750 that penetrates the hour hand drive shaft 740 and is used to drive the minute hand 720 to rotate, and a second hand drive shaft 760 that penetrates the minute hand drive shaft 750 and is used to drive the second hand 730 to rotate.
[0024] The shockproof watch head also includes a shockproof component, which includes a movement cover 800 and a fixed spring 900. The movement cover 800 includes a first connecting part 810 crimped on the upper surface of the movement 500 and screwed to the movement 500, a second connecting part 820 fixedly connected to the first connecting part 810 and abutting against the side surface of the movement 500 ring, and a third connecting part 830 located below the second connecting part 820 and fixedly connected to the second connecting part 820. The end of the third connecting part 830 is provided with a first inclined surface 831, and the inner wall of the watch case 100 is provided with a second inclined surface 110 adapted to the shape of the first inclined surface 831, and the first inclined surface 831 is abutted against the second inclined surface 110. In this embodiment, the first connecting portion 810, the second connecting portion 820, and the third connecting portion 830 are integrally formed. The contour of the surface of the second connecting portion 820 adjacent to the movement 500 is adapted to the contour of the side surface of the movement 500, so that the second connecting portion 820 abuts against the side surface of the movement 500. Thus, by securing the movement cover 800 to the movement 500, the movement cover 800 is aligned with the outer surface of the movement 500, thereby pressing the movement 500 against the movement 500. Furthermore, the mutual abutment between the first inclined surface 831 on the third connecting portion 830 and the second inclined surface 110 on the inner wall of the watch case 100 enables the movement cover 800 to cooperate with the watch case 100, thereby indirectly connecting the movement 500 to the watch case 100, thereby positioning the movement 500 within the inner cavity of the watch case 100 and preventing the movement 500 from shaking during use of the watch. The fixing spring 900 includes a fixing portion 910 screwed to the inner wall of the watch case 100, and an elastic abutment portion 920 fixedly connected to the fixing portion 910 and elastically pressed against the side of the third connecting portion 830 adjacent to the dial 600. By screwing the fixing spring 900 to the inner wall of the watch case 100 and elastically pressing the fixing spring 900 against the movement cover 800, when the watch is subjected to an external impact, the first inclined surface 831 disengages from the second inclined surface 110. During this process, the movement cover 800 lifts and squeezes the fixing spring 900, causing the fixing spring 900 to deform, thereby converting the external impact or vibration acting on the watch into elastic potential energy of the fixing spring 900. In other words, the shockproof component is arranged between the case 100 and the movement 500, so that the impact from the outside of the case 100 is buffered before reaching the inside of the movement cover 800, which can effectively reduce the damage to the movement 500 and the dial 600 caused by the impact. In addition, the shockproof component has a compact structure, which saves space inside the watch and reduces the impact on the appearance design of the watch.
[0025] In one embodiment, both the movement cover 800 and the fixing spring 900 are annular structures disposed around the movement 500. The annular movement cover 800 and the movement 500 are secured in position by multiple screw connections, thereby enhancing the stability of the connection between the movement cover 800 and the movement 500. Similarly, the annular fixing spring 900 is secured in position by multiple screw connections to the inner wall of the watch case 100, thereby enhancing the stability of the connection between the fixing spring 900 and the watch case 100. In another embodiment, the shockproof component includes multiple fixing springs 900 disposed around the movement 500 and screwed to the inner wall of the watch case 100, and multiple movement covers 800 that elastically engage with each fixing spring 900 and are screwed to the movement 500. Preferably, multiple fixing springs 900 are evenly distributed around the ring side of the movement 500, and multiple movement covers 800 are evenly distributed around the ring side of the movement 500. This ensures uniform force on the movement 500, thereby improving the stability of the fit between the movement 500 and the watch case 100. By providing multiple fixing springs 900 and movement covers 800, while achieving stable installation of the movement 500, the material consumption of the shockproof components is reduced, thereby reducing the manufacturing cost of the watch. In another embodiment, the elastic abutment portion 920 of the fixing spring 900 is annular in structure, and multiple protrusions are spaced apart on the outer ring side of the elastic abutment portion 920 to form a fixing portion 910.
[0026] In one embodiment, the angle between the first bevel 831 and the axial direction of the movement 500 (i.e., the inclination angle of the first bevel 831) is 30-60°, and the angle between the second bevel 110 and the axial direction of the movement 500 (i.e., the inclination angle of the second bevel 110) is 30-60°. Preferably, the angle between the first bevel 831 and the axial direction of the movement 500 is 45°, and the angle between the second bevel 110 and the axial direction of the movement 500 is 45°. In this embodiment, the inclination angle of the first bevel 831 is the same as the inclination angle of the second bevel 110. The inclination angle of the first bevel 831 is set between 30-60°, and the inclination angle of the second bevel 110 is set between 30-60°. This can avoid the problem of insufficient support force of the second bevel 110 on the first bevel 831 and movement of the movement cover 800 relative to the watch case 100 caused by the inclination angle of the first bevel 831 and the second bevel 110 being too small. It can also avoid the problem of insufficient installation area of the fixing part 910 caused by excessive inclination angle of the first bevel 831 and the second bevel 110.
[0027] In one embodiment, the inner wall of the watch case 100 protrudes toward the movement 500 to form a first step 120. The upper surface of the first step 120 is flat. The lower surface of the fixing portion 910 abuts the upper surface of the first step 120 and is fixedly connected to the first step 120 via a first screw 930. The second inclined surface 110 is formed at the edge of the upper surface of the first step 120. Furthermore, an elastic abutting portion 920 is located on a side of the fixing portion 910 adjacent to the movement 500 and is fixedly connected to the top of the fixing portion 910. Preferably, the fixing portion 910 and the elastic abutting portion 920 are integrally formed, and the fixing spring 900 is made of an elastic plastic, for example, PU (polyurethane) or TPE (thermoplastic elastomer). This reduces the weight of the shock-absorbing component, thereby reducing the impact of the shock-absorbing component on the weight of the watch. In this embodiment, a first through hole 911 is formed on the fixing portion, a first screw hole 121 is formed on the upper surface of the first step 120, a first screw 930 passes through the first through hole 911 and is inserted into the first screw hole 121, and the length of the first screw 930 is less than or equal to the sum of the depths of the first through hole 911 and the first screw hole 121, so that after the first screw 930 is tightened on the watch case 100, the top of the screw head of the first screw 930 is lower than the upper surface of the fixing portion, or is flush with the upper surface of the fixing portion. Preferably, the screw head of the first screw 930 is a frustum-shaped structure, the first through hole 911 is a conical hole whose inner contour is adapted to the outer contour of the screw head of the first screw 930, and the depth of the first through hole 911 is greater than or equal to the height of the screw head of the first screw 930, so that the installation depth of the first screw 930 is limited by the inner wall of the first through hole 911.
[0028] A second step is formed on the side of the third connecting portion 830 facing away from the movement 500 at the distal end of the first inclined surface 831. The lower surface of the elastic abutment portion 920 elastically abuts against the upper surface of the second step. The first connecting portion 810 is fixedly connected to the upper surface of the movement 500 via a second screw 840. It can also be understood that the lower portion of the second connecting portion 820 facing away from the movement 500 is raised to form the third connecting portion 830 extending toward the back cover 400, and the top surface of the third connecting portion 830 is the upper surface of the second step. Furthermore, a second through hole 811 is formed in the first connecting portion 810, and a second screw hole 510 is formed on the upper surface of the movement 500. The second screw 840 passes through the second through hole 811 and is inserted into the second screw hole 510. The length of the second screw 840 is less than or equal to the sum of the depths of the second through hole 811 and the second screw hole 510, so that after the second screw 840 is tightened on the movement 500, the top of the screw head of the second screw 840 is flush with the upper surface of the first connecting portion 810. Preferably, the screw head of the second screw 840 is a frustum-shaped structure, the second through hole 811 is a tapered hole with an inner contour adapted to the outer contour of the screw head of the second screw 840, and the depth of the second through hole 811 is greater than or equal to the height of the screw head of the second screw 840, so that the installation depth of the second screw 840 is limited by the inner wall of the second through hole 811.
[0029] In one embodiment, the distance between the dial 600 and the movement 500 is greater than zero, and the lower surface of the dial 600 abuts the first connecting portion 810. In other words, the dial 600 is connected to the movement 500 by abutting the first connecting portion 810. Simultaneously, the dial 600 does not contact any other parts of the movement 500 other than the watch head of the shock-resistant watch. Therefore, when the watch is subjected to an external impact, the shock and vibration transmitted to the dial 600 are minimal. This eliminates the need for high-strength materials for the dial 600, and allows for more brittle materials such as aventurine and mother-of-pearl to be used, increasing the design diversity of the dial 600.
[0030] The present invention also discloses a watch, which includes the above-mentioned shockproof watch head, and further includes a handle that passes through the watch case 100 and is drivingly connected to the movement 500, and a watch strap connected to the outer surface of the watch case 100. When the watch adopts the above-mentioned shockproof watch head, when the watch is worn and subjected to an external impact, the movement outer cover 800 is misaligned with the second inclined surface 110 of the inner wall of the watch case 100 under the action of the impact, so that the first inclined surface 831 is separated from the second inclined surface 110. In this way, the elastic abutment portion 920 at the end of the fixed spring 900 is bent and deformed in a direction away from the back cover 400, and the impact and vibration applied to the watch case 100 from the outside is converted into elastic potential energy of the fixed spring 900, which greatly weakens or even eliminates the impact transmitted to the movement 500, thereby achieving shockproof protection for the movement 500.
[0031] The above-mentioned shockproof watch head and watch have a movement cover 800 fixed on the movement 500, and a fixed spring piece 900 installed on the inner wall of the case 100. The axial and radial positioning of the movement 500 are achieved through the elastic cooperation between the fixed spring piece 900 and the movement cover 800, and the abutment between the first inclined surface 831 on the movement cover 800 and the second inclined surface 110 on the inner wall of the case 100. When the watch is subjected to axial or radial impact, the movement cover and the second inclined surface 110 on the inner wall of the case 100 are relatively misaligned, and then the fixed spring piece 900 plays a buffering role to reduce the damage to the movement 500 and the dial 600 caused by the impact, thereby improving the shockproof performance of the watch; the shockproof component has a compact structure, which greatly reduces the space occupied inside the watch compared to the traditional shockproof structure, which is conducive to improving the diversity of the watch's appearance design.
[0032] 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.
[0033] 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.
