Description

Technical Field

[0001] This utility model belongs to the field of pressure-holding fixture technology, specifically, it relates to a pressure-holding fixture for smart wearable devices. Background Technology

[0002] During the assembly of smartwatch products, after the various parts are bonded together with adhesive or glue, the assembled product needs to be pressurized to ensure the stability of the bond. The pressurizing fixture is used to assist in pressurizing the product.

[0003] In existing technologies, the pressure-holding fixture for the smartwatch frame typically uses upper and lower pressure plates to lock the product together. Decorative parts, which are glued to the surface of the smartwatch frame, are evenly pressed within a set time, resulting in a tighter fit between the decorative parts and the smartwatch frame. However, while vertically attached decorative parts can be evenly pressed by the upper and lower pressure plates, horizontally attached decorative parts cannot achieve the same even pressure holding effect due to the contouring positioning blocks on the upper and lower pressure plates. Furthermore, the locking mechanism of the upper and lower pressure plates has poor stability during the pressing process. Slight wobbling occurs when moving the pressure-holding fixture during the initial pressure holding stage, leading to uneven pressure on the decorative parts and the smartwatch frame. The poor flowability of the adhesive results in inconsistent thickness after curing, and the decorative parts are not tightly bonded to the smartwatch frame, making them prone to detachment. Summary of the Invention

[0004] The main objective of this utility model is to provide a pressure-holding fixture for smart wearable devices. This aims to solve the technical problems of existing smartwatch pressure-holding fixtures, where decorative parts horizontally attached to the side of the smartwatch frame cannot be evenly pressured by the contoured positioning blocks on the upper and lower pressure plates, and the upper and lower pressure plates have poor stability. Furthermore, slight shaking occurs when moving the pressure-holding fixture during the initial pressure-holding stage, resulting in uneven pressure on the decorative parts and the smartwatch frame, poor pressure-holding effect, and loose adhesion between the decorative parts and the smartwatch frame, making the decorative parts prone to detachment.

[0005] The present invention adopts the following technical solution:

[0006] A pressure-holding fixture for a smart wearable device includes a pressure-holding lower cover, a pressure-holding upper cover, a pressure-holding side cover, and a smartwatch frame. The pressure-holding upper cover is provided with multiple positioning posts, the pressure-holding lower cover is provided with positioning post holes that connect with the positioning posts, the pressure-holding lower cover is provided with multiple snap-on plates, the pressure-holding upper cover is provided with snap-on holes that engage with the snap-on plates, and the pressure-holding side cover is fastened to the side of the pressure-holding lower cover and the pressure-holding upper cover. The side of the pressure-holding lower cover and the pressure-holding upper cover is provided with multiple side positioning truncated cones and side snap-on posts. The pressure-holding side cover is provided with side positioning holes that correspond to the side positioning truncated cones and side snap-on holes that engage with the side snap-on plates.

[0007] The end of the positioning post hole is provided with a groove, and a positioning frustum located at the end of the positioning post is provided in the groove. A layer of conformal gasket is pasted on the inner surface of the groove. A circular gasket is pasted on the inner surface of the side positioning hole. The buckle plate and buckle hole fastening point and the side buckle plate and side buckle hole fastening point are both provided with buckle protrusions located on the pressure holding top cover and the pressure holding side cover.

[0008] Furthermore, the pressure-holding lower cover is provided with multiple convex mid-frame positioning modules for positioning the mid-frame of the smartwatch, the pressure-holding upper cover is provided with decorative contour positioning blocks that cooperate with the mid-frame positioning modules, and the pressure-holding side cover is provided with side decorative contour positioning blocks that cooperate with the mid-frame positioning modules.

[0009] Furthermore, silicone pad grooves are provided at the contact points between the mid-frame positioning module, the decorative part contour positioning block, and the side decorative part contour positioning block and the mid-frame of the smartwatch, and silicone pads are pasted inside the silicone pad grooves.

[0010] Furthermore, the positioning post hole has a hollow hole that extends through both ends, and the diameter of the hollow hole is smaller than the diameter of the groove.

[0011] Furthermore, the end of the buckle plate away from the pressure-holding top cover and the end of the side buckle plate away from the pressure-holding side cover are both provided with reinforcing ribs.

[0012] Furthermore, the pressure-holding lower cover, pressure-holding upper cover, pressure-holding side cover, and smartwatch frame are all integrally injection molded.

[0013] Beneficial effects:

[0014] In this utility model: 1. By setting pressure-holding side covers on the sides of the pressure-holding lower cover and the pressure-holding upper cover, and using contoured positioning blocks on the side decorative parts of the pressure-holding side cover, pressure can be applied to the decorative parts on the side of the smartwatch frame, resulting in uniform pressure and good pressure-holding effect; 2. Grooves are set at the ends of multiple positioning pin holes on the pressure-holding lower cover, and contoured positioning pads are set in the grooves; and positioning truncated cones are set at the ends of multiple positioning pins on the pressure-holding upper cover. The positioning truncated cones cooperate with the grooves and the contoured pads in the grooves to position the decorative parts attached to the smartwatch frame in the vertical direction, thereby improving the pressure between the pressure-holding lower cover and the pressure-holding upper cover on the smartwatch frame. Pressure holding stability; Several side positioning truncated cones are set on the sides of the pressure holding lower cover and pressure holding upper cover. Circular gaskets are attached to the inner surface of the side positioning holes of the pressure holding side cover. The side positioning truncated cones and the circular gaskets attached to the side positioning holes cooperate with each other for positioning. The decorative parts are attached to the middle frame of the smartwatch horizontally for pressure holding. This improves the stability of the pressure holding side cover, pressure holding upper cover and pressure holding lower cover for the middle frame of the smartwatch. It achieves accurate positioning of the pressure holding lower cover, pressure holding upper cover and pressure holding side cover for the middle frame of the smartwatch, avoids slight shaking that may occur when moving the pressure holding fixture in the early pressure holding stage, and ensures a good pressure holding effect.

[0015] Meanwhile, multiple snap-fit ​​plates are set on the lower pressure-holding cover, and multiple side snap-fit ​​plates are set on the sides of the lower and upper pressure-holding covers. The snap-fit ​​plates engage with the snap-fit ​​holes on the upper pressure-holding cover, and the side snap-fit ​​plates engage with the side snap-fit ​​holes on the side pressure-holding covers. Protrusions are set at the engagement points of the snap-fit ​​holes on the upper and side pressure-holding covers, effectively eliminating the fit gaps in the snap-fit ​​mechanism. This makes the entire fixture more rigid and prevents minor displacement or vibration during the pressure-holding process. It ensures the stable transmission of the pressure holding pressure when the upper and lower pressure-holding covers are engaged and when the side pressure-holding covers are engaged with the upper and lower pressure-holding covers. This allows the decorative parts on the smartwatch frame to be evenly stressed and pressurized, improving the stability of the pressure holding force. It also determines the end point of the engagement stroke, avoiding excessive stress damage to the engagement head caused by excessive force applied by the operator, and playing a role in overload protection.

[0027] Reference Figures 1 to 5 This utility model proposes a pressure-holding fixture for smart wearable devices, including a pressure-holding lower cover 1, a pressure-holding upper cover 2, a pressure-holding side cover 3, and a smartwatch frame 4. The pressure-holding upper cover 2 is provided with multiple positioning posts 201. The pressure-holding lower cover 1 is provided with positioning post holes 101 that are connected to the positioning posts 201. The pressure-holding lower cover 1 is provided with multiple buckle plates 102. The pressure-holding upper cover 2 is provided with buckle holes 202 that are engaged with the buckle plates 102. The pressure-holding side cover 3 is fastened to the side of the pressure-holding lower cover 1 and the pressure-holding upper cover 2. The side of the pressure-holding lower cover 1 and the pressure-holding upper cover 2 is provided with multiple side positioning truncated cones 5 and side buckle posts 6. The pressure-holding side cover 3 is provided with side positioning holes 301 that correspond to the side positioning truncated cones 5 and side buckle holes 302 that cooperate with the side buckle plates 6.

[0028] Specifically, the smartwatch pressure-holding fixture uses a lower pressure-holding cover 1 and an upper pressure-holding cover 2 to position and hold the smartwatch frame 4. Multiple positioning posts 201 and positioning post holes 101 cooperate to ensure that the lower pressure-holding cover 1 and the upper pressure-holding cover 2 fix the smartwatch frame 4 to its respective unique position. Multiple snap-fit ​​plates 102 and snap-fit ​​holes 202 cooperate to stably lock the lower pressure-holding cover 1 and the upper pressure-holding cover 2 into the smartwatch frame 4. During the pressure-holding process, continuous and uniform pressure is applied to the decorative parts attached to the top and bottom of the smartwatch frame 4 to ensure... The adhesive surfaces are in full contact to eliminate air bubbles, thus forming a firm and seamless bond. This ensures that the decorative parts of the smartwatch frame 4 are stably and evenly stressed and pressure-retained in the vertical direction. The side positioning frustum 5 and the side buckle post 6 are connected and positioned to cooperate with the side buckle hole 302 of the side buckle plate 6. This stably fastens the pressure-retaining side cover 3 to the sides of the pressure-retaining lower cover 1 and the pressure-retaining upper cover 2, providing continuous and even pressure to the horizontal decorative parts on the sides of the smartwatch frame 4, ensuring that the horizontal decorative parts on the sides of the smartwatch frame 4 are stably and evenly stressed and pressure-retained.

[0029] A groove 103 is provided at the end of the positioning post hole 101. A positioning frustum 203 located at the end of the positioning post 201 is provided in the groove 103. A layer of contour gasket 104 is attached to the inner surface of the groove 103. A ring gasket 303 is attached to the inner surface of the side positioning hole 301. The buckle plate 102 and the buckle hole 202 are fastened together, and the side buckle plate 6 and the side buckle hole 302 are fastened together. Buckle protrusions 7 are provided on the pressure holding cover 2 and the pressure holding side cover 3.

[0030] Specifically, the positioning platform 203, groove 103, and contoured gasket 104 within the groove 103 are mutually engaged and positioned to maintain pressure on the smartwatch frame 4 in the vertical direction after the decorative parts are attached. This prevents slight wobbling that may occur when moving the pressure-maintaining fixture during the initial pressure-maintaining stage, and improves the stability of the pressure-maintaining lower cover 1 and upper cover 2 on the smartwatch frame 4. Similarly, the side positioning platform 5, side positioning hole 301, and annular gasket 303 within the side positioning hole 301 are mutually engaged and positioned to maintain pressure on the smartwatch frame 4 in the horizontal direction after the decorative parts are attached. This improves the stability of the pressure-maintaining side cover 3, upper cover 2, and lower cover 1 in maintaining pressure on the smartwatch frame 4, achieving precise positioning of the smartwatch frame 4 by the lower cover 1, upper cover 2, and side cover 3, and preventing slight wobbling that may occur when moving the pressure-maintaining fixture during the initial pressure-maintaining stage. Slight shaking ensures good pressure holding effect; at the same time, multiple buckle plates 102 are fastened to buckle holes 202, and side buckle plates 6 are fastened to side buckle holes 302. The buckle holes 202 and multiple buckle plates 102 of the pressure holding top cover 2 and the buckle holes of the pressure holding side cover 3 are provided with protrusions, which effectively eliminate the fit gap in the buckling mechanism, making the structure of the entire fixture more rigid. No slight displacement or shaking will occur during the pressure holding process, ensuring the stable transmission of the pressure holding pressure when the pressure holding top cover and pressure holding bottom cover are fastened, and the pressure holding pressure when the pressure holding side cover and pressure holding top cover and pressure holding bottom cover are fastened. This allows the decorative parts attached to the smartwatch frame 4 to be evenly stressed and pressurized, improving the stability of the pressure holding force. It also determines the end point of the fastening stroke, avoiding excessive stress damage to the fastening head caused by excessive force by the operator, and playing a role in overload protection.

[0031] refer to Figures 1 to 5 In one embodiment, the pressure-holding lower cover 1 is provided with a plurality of convex mid-frame positioning modules 105 for positioning the mid-frame 4 of the smartwatch, the pressure-holding upper cover 2 is provided with decorative part contour positioning blocks 205 that cooperate with the mid-frame positioning modules 105, and the pressure-holding side cover 3 is provided with side decorative part contour positioning blocks 304 that cooperate with the mid-frame positioning modules 105.

[0032] Specifically, multiple convex mid-frame positioning modules 104, mimicking the shape of the bottom of the smartwatch mid-frame 4, precisely position the bottom of the smartwatch mid-frame 4. Decorative parts are glued on in the vertical direction of the smartwatch mid-frame 4. The decorative part contour positioning block 205 cooperates with the pressure-holding upper cover 2 and the pressure-holding lower cover 1 to determine the pressure-holding stroke of the decorative part, precisely positioning and holding the decorative part, so that the decorative part fits tightly with the smartwatch mid-frame 4.

Silicone pads 9 are pasted into the silicone pad grooves 8, thereby reducing scratches or bumps caused by mutual contact between the smartwatch mid-frame 4 and its decorative parts and the mid-frame positioning module 104, the decorative part contouring positioning block 205, and the side decorative part contouring positioning block 304 during the pressure holding process. This helps to improve the appearance quality of the product, ensures that the smartwatch mid-frame decorative parts are subjected to balanced force during the pressure holding process, and thus ensures that the decorative parts are firmly attached to the smartwatch mid-frame, guaranteeing the pass rate of the airtightness test.

[0034] refer to Figures 1 to 5 In one embodiment, the positioning post hole 201 has a hollow hole 206 extending through both ends. The diameter of the hollow hole 206 is smaller than the diameter of the groove 203. The hollow hole 206 is designed to make the pressure-holding lower cover 1 and the pressure-holding upper cover 2 fit more tightly when they are fastened together. During the pressure-holding process, the air in the groove 203 can be discharged through the hollow hole 206, thereby avoiding interference with the pressure-holding force and pressure-holding stroke, and making the decorative part fit more tightly with the smartwatch frame.

[0035] refer to Figures 1 to 5 In one embodiment, the end of the snap-on plate 102 away from the pressure-holding top cover 2 and the end of the side snap-on plate 6 away from the pressure-holding side cover 3 are both provided with reinforcing ribs 10 to prevent the cantilever beams of the snap-on plate 102 and the side snap-on plate 6 from undergoing plastic deformation or breakage during repeated snapping and separation, thereby improving their lifespan, holding force and assembly feel, facilitating pressure holding of the pressure-holding fixture and improving the pressure-holding force effect.

[0036] refer to Figures 1 to 5 In one embodiment, the pressure-holding lower cover 1, the pressure-holding upper cover 2, the pressure-holding side cover 3, and the smartwatch frame 4 are all integrally injection molded.
