Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to a watch case with a middle frame support structure. Background Technology

[0002] Bluetooth watches and children's watches require waterproofing and dustproofing. The display screen and watch case need to be bonded with high-viscosity hot melt adhesive. To meet the IP68 waterproof rating, the amount of adhesive used must be at the maximum limit. After bonding the watch case and display screen, in order to fully activate the adhesive and achieve the best bonding effect, pressure is maintained by heavy objects or pressure clamps. Under pressure, the adhesive will flow and overflow onto the watch face, which needs to be wiped off by personnel.

[0003] To address these issues, the industry currently focuses on adjusting the amount of adhesive to minimize overflow. However, manual wiping remains essential, and this process can also have negative consequences, including: 1. The wiping process can easily increase the defect rate of products; 2. Alcohol is required for wiping before the glue is fully cured. It cannot be wiped after curing, as alcohol will corrode the glue and affect the waterproof effect. 3. The wiping process requires dedicated operators. In order to improve the yield rate, additional training is also needed for the wiping operation, which increases the overall cost. To solve the above problems, a watch case with a middle frame support structure is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a watch case with a middle frame support structure to solve the problem of glue overflow in existing electronic watches during screen installation, as mentioned in the background art. The traditional method of manual wiping has the problems of affecting the yield rate, affecting the watch's water resistance, and increasing production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a watch case with a mid-frame support structure, comprising a mid-frame, wherein the upper and lower openings of the mid-frame are respectively provided with adhesive application assembly parts for mounting the watch cover and the display screen, the adhesive application assembly part comprising a support step and a support protrusion integrally formed on the support step, the support step being integrally formed on the mid-frame and recessed in the upper and lower end faces of the mid-frame, one side of the support protrusion being connected to the inner wall of the mid-frame, and the inner sides of the watch cover and the display screen respectively abutting against the top of the support protrusion, so that an adhesive storage chamber is formed between the multiple support protrusions, thereby preventing adhesive from overflowing to the outside of the mid-frame when fixing the watch cover and the display screen.

[0006] Preferably, the width of the support protrusion is between 0.25 and 0.3 mm.

[0007] Preferably, the thickness of the support protrusion is between 0.12 and 0.15 mm.

[0008] Preferably, the two sides of the inner frame of the watch case are provided with arc-shaped rounded corners, and the top of the arc-shaped rounded corners is higher than the top of the support protrusion.

[0009] Preferably, the support protrusions are in multiple groups, and the multiple groups of support protrusions are distributed equidistantly around the inner wall of the middle frame of the watch case.

[0010] Preferably, the width of the support step is greater than the width of the support protrusion, so that the inner side of the support step forms an adhesive application area lower than the support step.

[0011] Preferably, the inner frame of the watch case has an integrally formed part assembly part, and each of the four corners of the part assembly part has an integrally formed fixing post.

[0012] Preferably, both ends of the watch case frame are integrally formed with watch strap fixing parts, and one side of the watch case frame is equipped with physical buttons.

[0013] Preferably, a watch cover assembly station is naturally formed between the back of the part assembly section and the watch case frame.

[0014] The technical effects and advantages of this utility model are as follows: This watch case with a mid-frame support structure works by applying adhesive to the inner top of the support steps, and then attaching the watch cover and display screen to the support steps on both sides. At this time, the watch cover and display screen abut against the support protrusions, so that the glue storage chamber formed between the multiple support protrusions can collect the glue that is squeezed outward when the watch cover and display screen are pressed and bonded, thus preventing the glue from overflowing onto the outside of the mid-frame of the watch case. This effectively solves the glue overflow problem in the current production process during adhesive bonding, eliminating the need for a glue wiping process. On the one hand, it improves the overall production efficiency, and on the other hand, by eliminating the glue wiping process, it avoids the impact of glue wiping on the production yield, avoids the corrosion of the glue by the alcohol used for wiping, which would affect the waterproof performance, and achieves the effect of cost reduction and efficiency improvement by reducing the number of processes and related personnel.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1 to 3 The watch case shown includes a mid-frame support structure, comprising a mid-frame 1. The upper and lower openings of the mid-frame 1 are respectively provided with adhesive application assembly parts 2 for mounting the watch cover and display screen. Each adhesive application assembly part 2 includes a support step 22 and a support protrusion 23 integrally formed on the support step 22. The support step 22 is integrally formed on the mid-frame 1 and is recessed into the upper and lower end faces of the mid-frame 1. One side of the support protrusion 23 is connected to the inner wall of the mid-frame 1. The inner sides of the watch cover and display screen abut against the top of the support protrusion 23, thereby forming an adhesive storage chamber 24 between the multiple support protrusions 23, thus preventing adhesive from overflowing to the outside of the mid-frame 1 when fixing the watch cover and display screen.

[0019] The width of the support protrusion 23 is between 0.25 and 0.3 mm.

[0020] The thickness of the support protrusion 23 is between 0.12 and 0.15 mm.

[0021] The two sides of the inner frame 1 of the watch case are provided with rounded corners 21. The top of the rounded corners 21 is higher than the top of the support protrusion 23. After the display screen is installed, the top surface of the display screen is flush with the top of the rounded corners 21.

[0022] The support protrusions 23 are in multiple groups, and the multiple groups of support protrusions 23 are distributed equidistantly around the inner wall of the middle frame 1 of the casing, thereby forming a complete and continuous support and adhesive storage function, avoiding unevenness in the screen installation.

[0023] The width of the support step 22 is greater than the width of the support protrusion 23, so that the inner side of the support step 22 forms an adhesive application area lower than the support step 22. During assembly, adhesive is applied to this adhesive application area by an adhesive applicator.

[0024] The inner frame 1 of the watch case has an integrally formed parts assembly section 4. Each of the four corners of the parts assembly section 4 has an integrally formed fixing post 5, on which the main board and battery of the watch are installed.

[0025] Both ends of the watch case frame 1 are integrally formed with watch strap fixing parts 3, which are fixed by pins. A physical button 7 is installed on one side of the watch case frame 1. By pre-assembling the physical button 7, damage to internal parts can be avoided during later assembly.

[0026] The back of the parts assembly section 4 and the middle frame 1 of the watch case naturally form the watch cover assembly station 6, which is used to assemble the watch cover during assembly.

[0027] Working principle: When in use, the device applies glue to the inner top of the support steps 22, and then attaches the watch cover and display screen to the support steps 22 on both sides. At this time, the watch cover and display screen abut against the support protrusions 23, so that the glue storage chamber 24 formed between the multiple support protrusions 23 can collect the glue that is squeezed outward when the watch cover and display screen are pressed and bonded, thereby preventing the glue from overflowing to the outside of the watch case frame 1. This effectively solves the glue overflow problem in the current production process when gluing and fixing, eliminating the need for a glue wiping operation. On the one hand, it improves the overall production efficiency, and on the other hand, by eliminating the glue wiping operation, it avoids the glue wiping operation affecting the production yield, avoids the alcohol used for glue wiping from corroding the glue and affecting the waterproof performance, and achieves the effect of cost reduction and efficiency improvement by reducing the number of processes and related personnel.

[0028] In Example 2, the width of the support protrusion 23 is 0.25mm and the thickness of the support protrusion 23 is 0.12mm. At this time, the capacity of the glue storage chamber 24 formed between the multiple support protrusions 23 is the smallest. The minimum standard amount should be controlled when applying glue. At the same time, due to the decrease in the height of the support protrusion 23, the drop between the end face of the display screen and the middle frame 1 of the casing is minimized, making the overall appearance more aesthetically pleasing.

[0029] In Example 3, the width of the support protrusion 23 is 0.3mm and the thickness of the support protrusion 23 is 0.15mm. At this time, the capacity of the glue storage chamber 24 formed between the multiple support protrusions 23 is the largest, and its anti-overflow effect is the best when in use.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
