Description

Technical Field

[0001] The utility model relates to a mobile phone case, in particular to a mobile phone case in which a case back plate and a case frame of a finished product are fixedly connected together. Background Art

[0002] The mobile phone case in the prior art includes a case back plate and a case frame. Usually, the case back plate and the case frame are made into an integrated structure through a conventional injection molding process. The mobile phone case made with this structure has a single and old-fashioned appearance, which does not excite young people with diverse preferences today. At the same time, the mold cost used to make this type of mobile phone case is also relatively high. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a mobile phone case which can connect two separated case back plates and case frames together to form a strong combination strength and visual three-dimensional effect.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] The mobile phone case of the utility model comprises a case back plate and a case frame fixedly connected to the case back plate, and is characterized in that the case back plate and the case frame are two separately manufactured components, a plurality of through parts are arranged at intervals around the case back plate, and one side of the case frame is arranged at intervals with connection parts having the same number as the through parts on the case back plate, and each connection part is correspondingly embedded in one of the through parts so that the case back plate and the case frame are fixedly connected together.

[0006] The shell frame is an injection-molded part connected to the shell back plate through an injection molding process.

[0007] The shell frame is an independently manufactured component, which is connected to the shell back plate through an adhesive structure.

[0008] The through-hole is a circular hole, an elliptical hole or a regular polygonal hole, and the outer diameter of the through-hole is 0.5-2.5 mm.

[0009] The through portion is an elliptical hole, the maximum outer diameter of the elliptical hole is 1.5-2.5 mm, and the minimum outer diameter of the elliptical hole is 0.5-1.0 mm.

[0010] The through portion is an elliptical hole, and the hole size of the elliptical hole is 0.9 mm×2.0 mm.

[0011] The distance between two adjacent through-holes is 5-25 mm.

[0012] The distance between two adjacent through-holes is 10-15 mm.

[0013] The shell frame further includes a covering portion, which is an integral structure with the connecting portion, and the covering portion completely covers the openings at both ends of each of the through portions of the shell back plate.

[0014] A mortise and tenon interlocking structure is also provided between the shell back plate and the shell frame to connect the two.

[0015] Compared with the prior art, the utility model fixes the separated shell back plate and shell frame together by means of a male-female bite of a plurality of through parts arranged on the shell back plate and a connecting part arranged on the shell frame, which not only can enhance the connection strength between the shell back plate and the shell frame, but also has the advantage of simplifying the manufacturing process of the mobile phone case. At the same time, when the shell back plate and the shell frame are transparent and of different colors, the male-female bite structure between the through parts and the connecting parts can also bring a stronger visual three-dimensional sense to the user.

[0022] like Figure 1 As shown in FIG. 4 , the mobile phone case of the present invention comprises a case back plate 1 and a case frame 2.

[0023] 1. The shell back plate 1 is a pre-made finished product, which can be made of plastic or metal, and its color can be a single color or a combination of multiple colors.

[0024] A lens frame 6 and a magnetic ring 7 of a conventional structure are provided on the shell back plate 1. The shell back plate 1 is in the shape of a rectangle, and an annular groove 4 is provided along its periphery. In the groove 4, a plurality of through portions 3 penetrating the shell back plate 1 are provided at intervals along the periphery. The through portions 3 have various shapes, which may be circular holes, elliptical holes, and regular polygonal holes.

[0025] The maximum outer diameter of the through-portion 3 is 2.5 mm. The utility model is preferably an elliptical hole, and the maximum outer diameter b of the hole size of the elliptical hole is 1.5-2.5 mm, and the minimum outer diameter a of the elliptical hole is 0.5-1.0 mm, preferably a×b=0.9 mm×2.0 mm. The spacing h between two adjacent through-portions 3 is 5-25 mm, preferably h is 10 mm-15 mm. The aperture of the through-portion 3 and the spacing data between two adjacent through-portions 3 can ensure that when the shell back plate 1 and the shell frame 2 are combined together, they have a high connection strength, and can also avoid the breakage of the edge of the shell back plate 1 and the main body due to the setting of several through-portions 3, which is similar to the indentation line.

[0026] Furthermore, in order to improve the bonding strength between the shell back plate 1 and the shell frame 2, a mortise and tenon interlocking structure 5 that enables the two to be bonded together may be provided in a partial area between the shell back plate 1 and the shell frame 2, such as at a corner.

[0027] 2. Shell frame 2

[0028] Shell frame 2 has the following two types:

[0029] 1) The molten plastic is injected into a frame mold mounted on the shell back plate 1 through an injection molding process.

[0030] When the molten plastic injected into the frame mold cools down, connecting parts 8 of the same number as the through parts 3 will be formed around the shell frame 2, and these connecting parts 8 are filled in the corresponding through parts 3 one by one, thereby combining the shell back plate 1 and the shell frame 2 together; at the same time, after the molten plastic cools down, an annular connecting rib connected to the shell back plate 1 as a whole will also be formed in the groove 4 of the shell back plate 1.

[0031] 2) The shell frame 2 is a pre-made finished product, and is provided with connecting parts 8 on its periphery in the same number as the through parts 3. When assembling the mobile phone case, a chemical adhesive is applied on the periphery of the shell frame 2, and then the connecting parts 8 on the shell frame 2 are inserted one by one into the corresponding through parts 3 to fix the shell back plate 1 and the shell frame 2 together.
