It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. In addition, in the description with reference to the drawings, the same marks in different drawings represent the same elements.

[0027] The present disclosure provides a housing of a mobile terminal, comprising:

[0028] A frame 1, wherein a first groove 11 is formed on the top of the frame 1, and a protrusion is formed on the top of the outer periphery of the first groove 11;

[0029] A cover body 2, wherein a docking frame 21 is disposed on one side of the cover body 2 facing the frame body 1; and

[0030] Adhesive backing 3, arranged between the frame body 1 and the cover body 2;

[0031] The protrusion is used to cooperate with the cover body 2 to reduce the gap between the cover body 2 and the frame body 1.

[0032] In one embodiment of the present disclosure, Figure 1-Figure 4 As shown, a first groove 11 is opened on the outer side of the top of the frame 1, and the adhesive 3 is a double-sided adhesive, one side of which is bonded in the first groove 11, and the other side of the adhesive 3 corresponds to the bottom wall of the docking frame 21. The cover body 2 and the frame body 1 are pressed and assembled, that is, the adhesive 3 is pressed and activated, and the protrusions set on the outer top surface of the frame body 1 cooperate with the notch on the outer edge of the cover body 2. Compared with the traditional technology, the appearance gap between the frame body 1 and the cover body 2 can be effectively reduced. The present invention effectively activates the adhesive 3 through the cooperation of the first groove 11 and the docking frame 21, thereby improving the sealing between the cover body 2 and the frame body 1.

[0033] The present disclosure does not limit the materials of the protrusion and the cover 2. In one embodiment of the present disclosure, the protrusion can be made of a material with self-healing properties, such as silicone or other flexible composite materials, to improve the tolerance of assembly. In addition, the notch of the cover 2 can be designed to have an elastic edge to better adapt to the cooperation with the protrusion.

[0034] In one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the main body of the cover body 2 is a planar structure.

[0035] In some traditional designs, an arc-shaped cover body is adopted, in which the cover body is surrounded and limited by a circle of surrounding frames of a frame body, and the assembly gap is exposed on the plane where the cover body is located. Compared with the arc-shaped cover body of the traditional technology, the present invention adopts a cover body 2 with a planar structure as the main body, and the matching gap between the cover body 2 and the frame body 1 is on the side of the overall appearance of the mobile phone, so that external impurities will not enter the interior of the mobile terminal body from the plane where the cover body 2 is located, and at the same time, the appearance of the mobile terminal is more beautiful.

[0036] In one embodiment of the present disclosure, Figure 1 and Figure 2 As shown, the docking frame 21 extends toward the frame body 1, and the bottom surfaces of the docking frame 21 are in the same plane.

[0037] The bottom surface of the docking frame 21 is in contact with the adhesive backing 3. When the cover body 2 is pressed down to the frame body 1 for assembly, due to the planar structure of the main body of the cover body 2, the pressure is evenly transmitted to the adhesive backing 3 through the plane of the bottom surface of the docking frame 21, so that the adhesive backing 3 is evenly bonded to the frame body 1 and the cover body 2 at various positions.

[0038] In one embodiment of the present disclosure, Figure 3 As shown, the shape of the bottom wall of the first groove 11 matches the shape of the bottom wall of the docking frame 21 , and the adhesive 3 is disposed between the first groove 11 and the docking frame 21 .

[0039] The shape of the bottom wall of the first groove 11 matches the shape of the bottom wall of the docking frame 21. The present disclosure does not limit the matching shapes of the first groove 11 and the docking frame 21. In one embodiment of the present disclosure, Figure 1 As shown, the bottom wall of the first groove 11 is designed to be sloped, and the bottom wall of the docking frame 21 is designed to be angled to match the slope.

[0040] In other embodiments of the present disclosure, the bottom wall of the first groove 11 and the bottom wall of the docking frame 21 may be provided with matching concave-convex surfaces or textures to increase the contact area with the adhesive backing 3 and improve the firmness of the assembly between the cover body 2 and the frame body 1.

[0041] In one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, a second groove 22 is provided on the periphery of the docking frame 21 facing the first groove 11 , and the second groove 22 matches the outer groove wall 12 of the first groove 11 .

[0042] In one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the outer groove wall of the second groove 22 has a notch that matches the protrusion.

[0043] In one embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the bottom width of the protrusion is greater than the top width. This structure is easy to produce and implement. Figure 3 and Figure 4 In the embodiment, the outer side of the second groove 22 has an oblique notch that cooperates with the protrusion, allowing the protrusion to guide the movement of the cover body when the cover body 2 is pressed against the frame body 1, thereby avoiding the protrusion from hindering the pressing of the cover body 2 during the assembly process.

[0044] In one embodiment of the present disclosure, Figure 4 As shown, the gap between the top surface of the non-raised portion on the outer groove wall 12 and the bottom wall of the second groove 22 is A, which is used to provide a pressing stroke for activating the adhesive 3.

[0045] The gap A ensures that when the cover body 2 and the frame body 1 are pressed and assembled, the cover body 2 has enough space to press against the frame body 1, thereby allowing the adhesive 3 to be fully activated.

[0046] In one embodiment of the present disclosure, Figure 4 As shown, the gap between the top surface of the raised portion on the outer groove wall 12 and the bottom wall of the second groove 22 is B, and the width of the gap B is smaller than the width of the gap A.

[0047] The gap B is the horizontal viewing angle gap of the appearance side when the cover body 2 and the frame body 1 cooperate. By providing a protrusion on the outer groove wall 12, the gap A at the horizontal viewing angle is blocked, thereby reducing the assembly gap on the appearance side, thereby further beautifying the appearance and solving the problem that the pressing stroke required to activate the adhesive backing 3 is large, while the appearance surface requires a small gap.

[0048] The present disclosure does not limit the size parameters of the protrusion, the thickness of the adhesive backing 3, the width of the gap A between the top surface of the non-protruding portion on the outer groove wall 12 and the bottom wall of the second groove 22, and the width of the gap B between the top surface of the protruding portion on the outer groove wall 12 and the bottom wall of the second groove 22. In one embodiment of the present disclosure, Figure 4 As shown, the width of the bottom surface of the protrusion that can be used is 0.35mm, the height is 0.11mm, the thickness of the adhesive backing is 0.25mm or 0.3mm, and the gap A=0.15mm after the cover body 2 and the frame body 1 are assembled, which meets the activation space requirement of the adhesive backing 3. At the same time, the horizontal viewing angle gap between the cover body 2 and the frame body 1 after assembly is only B=0.04mm, and the appearance gap is very small, which further improves the sealing of the assembly, optimizes the appearance of the product, and meets the quality requirements of the appearance design.
