[0023] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: Please see Figures 1 to 4 This is an embodiment of the anti-overflow adhesive type glare back cover 10 of the present utility model, which includes a back plate main body 100, a light-emitting component 200, a rear cover plate 300 and an adhesive 400. The light-emitting component 200 includes an annular lamp body 210 and a light guide ring 220. The outer side of the light guide ring 220, the rear cover plate 300 and one side of the back plate main body 100 together form an annular groove 100a. The annular lamp body 210 is located in the annular groove 100a so that the annular lamp body 210 is arranged around the light guide ring 220. The rear cover plate 300 has an installation opening 301 and an installation abutment area 302. The light guide ring 220 passes through the installation opening 301, and a portion of the structure of the light guide ring 220 is located within the installation abutment area 302. The installation abutment area 302 surrounds the installation opening 301. The rear cover plate 300 has a protruding first retaining ring 310 located within the installation abutment area 302. The light guide ring 220 has protruding second retaining ring 221 and third retaining ring 222. An annular groove 100a is formed between the adhesive ring 221 and the third adhesive ring 222. The first adhesive ring 310 is located within the annular groove 100a and abuts against the corner of the light guide ring 220 and the third adhesive ring 222. An annular adhesive channel 100b is formed between the annular groove 100a and the mounting contact area 302. The adhesive 400 is located in the annular adhesive channel 100b so that the light guide ring 220 and the rear cover plate 300 are connected by the adhesive 400. Furthermore, the first adhesive ring 310, the second adhesive ring 221, and the third adhesive ring 222 together prevent the adhesive 400 from overflowing to prevent structural contamination.

[0024] It can be understood that the adhesive blocking channel 100b is formed by the light guide ring 220 and its protruding second adhesive blocking ring 221, and the rear cover plate 300 and its protruding first adhesive blocking ring 310. The first adhesive blocking ring 310 and the second adhesive blocking ring 221 are used for primary adhesive blocking to prevent the adhesive 400 from overflowing, and the third adhesive blocking ring 222 is used for secondary adhesive blocking to further prevent the adhesive 400 from overflowing.

[0025] In the above embodiments, the anti-overflow adhesive type glare back cover forms an adhesive-blocking channel between the back cover plate and the light guide ring. The adhesive-blocking channel is formed on one side of the first adhesive-blocking ring, the light guide ring, the second adhesive-blocking ring, and the back cover plate. After assembling the phone back cover, the adhesive tends to overflow downwards along the direction of gravity. However, with the cooperation of the first and second adhesive-blocking rings, a portion of the adhesive remains between the first and third adhesive-blocking rings, preventing the adhesive from overflowing. A small amount of adhesive remains on the second adhesive-blocking ring, thereby effectively and multi-stage preventing adhesive overflow and ensuring the light output effect of the ring light body.

[0026] like Figure 2 and Figure 3 As shown, in one embodiment, the first adhesive retaining ring 310 and the second adhesive retaining ring 221 are arranged in parallel.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, the first adhesive-blocking ring 310 and the third adhesive-blocking ring 222 are arranged in parallel to ensure that the adhesive 400 is not prone to overflow.

[0028] like Figure 4 As shown, in one embodiment, the rear cover plate 300 has a limiting groove 303 located in the mounting abutment area 302. A limiting block 223 protrudes from the outer wall of the light guide ring 220 and is located within the limiting groove 303. Thus, the cooperation of the limiting groove 303 and the limiting block 223 restricts the rotation of the light guide ring 220, ensuring the stability of the structural installation.

[0029] like Figure 2 or Figure 3 As shown, in one embodiment, the side of the back cover 300 facing away from the annular groove 100a is flush with the top surface of the third adhesive ring 222, so that the overall structure of the anti-overflow adhesive type glare back cover 10 is not too protruding.

[0030] like Figure 5As shown, in one embodiment, the back panel body 100 includes an outer texture layer, a printing transfer layer, an electroplating layer, an ink layer, an adhesive layer, and a reinforcing fiberglass layer stacked sequentially. The outer texture layer is connected to the rear cover plate 300 and the light guide ring 220, respectively. The reinforcing fiberglass layer enhances the structural strength of the back panel body 100. Compared to ceramic or metal back panels, the fiberglass-based back panel body 100 is lighter. When a mobile communication device uses a reinforced fiberglass back panel body 100, the overall weight of the device can be reduced, minimizing discomfort caused by prolonged handheld use and meeting the needs of more users. Furthermore, the ink layer and the reinforcing fiberglass layer are connected by an adhesive layer, which fills microscopic gaps, forming a smooth transition layer and preventing the ink from cracking or peeling due to localized stress concentration.

[0031] Furthermore, the back panel body 100 also includes a marking layer, and the outer texture layer, the marking layer, and the printing transfer layer are sequentially stacked. This allows the marking to be printed on the back panel body 100 after its manufacturing is completed.

[0032] Furthermore, the printing transfer layer includes a varnish layer and a transfer layer, with the outer texture layer, varnish layer, transfer layer and marking layer stacked sequentially.

[0033] Furthermore, the manufacturing process of the back panel body 100 is as follows: roll-to-roll transfer of master mold adhesive → application of hardening liquid → logo → printing of varnish → transfer → electroplating → bottom cover → high pressure → lamination (providing 3 glass fiber prepregs and hot pressing) → pressing PC semi-finished product and glass fiber semi-finished product together → CNC processing.

[0034] In one embodiment, the thickness of the marker layer is 3-5 μm. In this embodiment, the thickness of the marker layer is 5 μm.

[0035] In one embodiment, the colloid 400 is a UV colloid.

[0036] This disclosure also provides a mobile communication device, including a communication device body and an anti-overflow adhesive type glare back cover 10 as described in any embodiment, wherein the anti-overflow adhesive type glare back cover 10 is installed on the back of the communication device body.

[0037] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned anti-overflow adhesive type glare back cover forms an adhesive-blocking channel between the back cover and the light guide ring. This channel is formed on one side of the first adhesive-blocking ring and the light guide ring, and on one side of the second adhesive-blocking ring and the back cover. After assembling the phone back cover, the adhesive tends to overflow downwards due to gravity. However, with the cooperation of the first and second adhesive-blocking rings, some of the adhesive remains between the first and third adhesive-blocking rings, preventing it from overflowing. A small amount of adhesive remains on the second adhesive-blocking ring, thus effectively and multi-stage preventing adhesive overflow and ensuring the light output effect of the ring light body.

[0038] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
