[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0052] Example 1
[0053] Please refer to Figure 5-7 An integrated touch module is provided, which includes a cover plate 1, a groove 101 is opened on the back surface of the cover plate 1, and the bottom surface of the groove 101 is flattened with optical glue 3.

As long as the display module 2 is inside the groove 101 on the back of the cover plate 1 after full bonding, it can be determined that the bonding is qualified. At the same time, the display module 2 can be installed quickly and conveniently, and after the display module 2 is bonded to the cover plate 1, the surface of the display module 2 is flush with the surface of the cover plate 1, which is convenient for the installation of the backlight module 4.
[0054] The cover plate 1 and the casing 5 are bonded by hot melt adhesive 6. At the same time, a sealing structure is formed between the casing 5 and the cover plate 1. The sealing structure is used to seal the hot melt adhesive 6 to prevent the hot melt adhesive 6 from overflowing, thereby improving the aesthetics and further improving the user experience.
[0055] Example 2
[0056] The integrated touch module structure provided in Example 1 is further optimized. Specifically, Figure 5-7 As shown, the housing 5 and the cover plate 1 are provided with hot melt adhesive 6 on the inner side of the sealing structure. Further, the cover plate 1 is provided with a first plane 102 between the groove 101 and the convex structure 103, and the housing 5 is provided with a second plane 501 corresponding to and fitting the first plane 102. The hot melt adhesive 6 is provided between the first plane 102 and the second plane 501, that is, the hot melt adhesive 6 is provided between the groove 101 and the sealing structure. After the hot melt adhesive 6 covers between the first plane 102 and the second plane 501, the housing 5 and the cover plate 1 are bonded and fixed.
[0057] Furthermore, the sealing structure includes an outer convex structure 103 and an inner concave structure 502, and the outer convex structure 103 and the inner concave structure 502 are aligned and buckled, and the outer convex structure 103 and the inner concave structure 502 are used to realize the alignment installation of the cover plate 1 and the housing 5, realize the positioning of the cover plate 1, and ensure the installation accuracy of the touch module. In this embodiment, the outer convex structure 103 is arranged on the outer edge of the cover plate 1 and is an integral structure with the cover plate 1, and the inner concave structure 502 is arranged on the outer edge of the housing 5. Of course, in actual production, the outer convex structure 103 can also be arranged on the housing 5, and the inner concave structure 502 can be arranged on the cover plate 1. The functions they play are the same, and this implementation structure is not described separately here.
[0058] Through the above-mentioned structural design, by setting the convex structure 103 on the cover plate 1 and the concave structure 502 on the casing 5, when the cover plate 1 and the casing 5 are bonded, the convex structure 103 is inserted into the concave structure 502 to realize the positioning of the cover plate 1, which is convenient for the rapid installation of the cover plate 1 and the casing 5. At the same time, the convex structure 103 can also block the hot melt adhesive 6, effectively preventing the hot melt adhesive 6 from overflowing, with beautiful appearance, improving user experience and product brand value.
[0059] Example 3
[0060] The integrated touch module structure provided in Example 2 is further optimized. Specifically, Figure 5-11 As shown, a glue placement groove is formed between the first plane 102 and the second plane 501, and the hot melt adhesive 6 is arranged in the glue placement groove, and the side wall of the glue placement groove is a slope structure.
[0061] In specific implementation, Figure 3 As shown, a first shallow groove 104 is opened on the first plane 102 of the cover plate 1, and the second shallow groove 503 can be prepared by chemical etching process or laser etching. Of course, it can also be formed integrally with the cover plate 1 when the cover plate 1 is manufactured. The hot melt adhesive 6 is covered in the shallow groove, which increases the bonding surface area on the one hand, and blocks the hot melt adhesive 6 to prevent overflow on the other hand.
[0062] On the other hand, a second shallow groove 503 may be provided on the second surface of the casing 5. The second shallow groove 503 is integrally prepared with the casing 5. The provision of the second shallow groove 503 increases the adhesive surface area between the cover plate 1 and the casing 5, further improving the adhesive strength.
[0063] Through the above structural design, a glue groove is formed at the position where the cover plate 1 and the casing 5 are attached to the hot melt glue 6. The glue groove is used to shield the hot melt glue 6 to further prevent the hot melt glue 6 from overflowing, and at the same time can increase the amount of glue, thereby improving the bonding strength.
[0064] Example 4
[0065] The integrated touch module structure provided in Example 3 is further optimized. Specifically, Fig.12 , 13 As shown, the side wall of the groove 101 is provided with a step groove 105, and the step groove 105 is arranged along the side wall of the groove 101, and the side wall outer dimensions of the step groove 105 are consistent with the outer dimensions of the backlight module 4. The backlight module 4 is placed on the step groove 105, and the backlight module 4 is flush with the step groove 105, which is convenient for the cover plate 1 and the casing 5 to be bonded.
[0066] Through the above structural design, a step groove 105 is set on the inner wall of the groove 101 of the cover plate 1, and the step groove 105 is used to support and limit the backlight module 4, so that the cover plate 1 limits the entire optical module, avoiding installation deviation and improving product quality.
[0067] The working principle of the integrated touch module structure provided by the utility model is as follows: after the cover plate 1, the display module 2, the backlight module 4 and the housing 5 are all produced and prepared, a layer of optical glue 3 is evenly applied in the groove 101 on the back side of the cover plate 1, and after the display module 2 and the backlight module 4 are connected together, the display module 2 is embedded in the groove 101 and fixed to the cover plate 1 by the optical glue 3, and the groove 101 and the optical glue 3 are used to fix and position the display module 2, and there is no need to add the white oil alignment line 7. As long as the display module 2 is attached, the backlight module 4 is fixed to the cover plate 1. When the module 2 is placed in the groove 101, it can be determined that the display module 2 is accurately fitted, which reduces consumables, reduces production costs, and facilitates subsequent quality inspection. The display module 2 is easy and quick to install, which can greatly improve the yield rate and reduce rework, thereby improving the company's benefits. The provided sealing structure can block the hot melt adhesive 6 to prevent the hot melt adhesive 6 from overflowing. The sealing structure is integrally formed with the casing 5 or the cover plate 1, and no additional process is required, which reduces the process flow, facilitates the installation of the cover plate 1 and the casing 5, greatly improves production efficiency, and thus improves product competitiveness.
