Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided to explain the principles of the invention and its practical application to thereby enable others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to the particular use contemplated. In the drawings, like reference numerals will be used to refer to like elements throughout.

Referring to fig. 1, fig. 2 and fig. 3, the mobile terminal provided in this embodiment includes a buckle structure, where the buckle structure includes a male buckle 1 and a female buckle 2, where the male buckle 1 is a rear shell of the mobile terminal, and the female buckle 2 is a front shell of the mobile terminal. The male buckle 1 includes a male buckle body 11 and a buckle 12 disposed on the male buckle body 11. The female buckle 2 includes a female buckle body 21 and a buckle slot 22 disposed on the female buckle body 21. The buckle 12 includes a connecting portion 12a protruding from the buckle body 11 along a first direction, and a buckling portion 12b bent and extended from the connecting portion 12a along a second direction, and the buckle 12 cooperates with the buckle slot 22 to buckle the male buckle 1 and the female buckle 2.

Specifically, in order to improve the reliability of the buckle structure, the first direction is perpendicular to the second direction, the first direction is the y direction in fig. 1, and the second direction is the x direction in fig. 1.

In order to make the male buckle 1 and the female buckle 2 combined more tightly, the buckling part 12b is located at one end of the connecting part 12a far away from the male buckle body 11. Preferably, the engaging portion 12b is located in the middle of one end of the connecting portion 12a away from the male buckle body 11. Therefore, the material can be saved while the buckling function is realized, and the service life and the strength are prolonged.

In order to improve the user's hand and to obtain a longer service life, the cross-sectional shape of the fastening portion 12b is trapezoidal. The engaging portion 12b is a prism, and includes a first engaging surface 100, the connecting portion 12a includes a second engaging surface 101, the first engaging surface 100 and the second engaging surface 101 are located on the same side of the connecting portion 12a, the female buckle body 21 has a third engaging surface 102 and a fourth engaging surface 103 located on one side of the buckle slot 22, the third engaging surface 102 engages with the first engaging surface 100, and the fourth engaging surface 103 engages with the second engaging surface 101.

When buckling pin 1 and box 2, buckling part 12b is earlier taken place elastic deformation by fourth fitting surface 103 extrusion and is removed along fourth fitting surface 103, when buckling part 12b moved the position of third fitting surface 102, buckling part 12b recovered to the uncompressed state under the effect of self elastic deformation power, at this moment, first fitting surface 100 just laminates with third fitting surface 102, second fitting surface 101 just laminates with fourth fitting surface 103, whole buckle 12 block is in buckle groove 22 completely, thereby buckle pin 1 and box 2.

In order to further improve the reliability of the snap structure, the female snap body 21 protrudes with a positioning portion 21a along the second direction, and the positioning portion 21a abuts against the connecting portion 12a when the male snap 1 is snapped with the female snap 2. Preferably, the positioning portion 21a is perpendicular to the connecting portion 12 a. When the male buckle 1 and the female buckle 2 are buckled, the bottom surface of the connecting portion 12a is attached to the surface of the positioning portion 21 a.

In order to further improve the hand feeling, a groove 10 is arranged on the surface of the connecting part 12a opposite to the buckling part 12b, and a boss 20 corresponding to the groove 10 is arranged on the female buckle body 21. The connecting portion 12a further includes a fifth mating surface 104, the fifth mating surface 104 and the second mating surface 101 are respectively located at two sides of the connecting portion 12a, the female buckle body 21 has a sixth mating surface 105 located at the other side of the buckle slot 22, and the sixth mating surface 105 is mated with the fifth mating surface 104.

When the male buckle 1 is disassembled from the female buckle 2, the buckle 12 moves along the sixth mating surface 105 and the third mating surface 102, the engaging portion 12b is pressed to be elastically deformed and moves along the sixth mating surface 105, when the engaging portion 12b moves to the position of the fourth mating surface 103, the engaging portion 12b is pressed again until the engaging portion 12b moves out of the buckle groove 22, and at this time, the engaging portion 12b is restored to the uncompressed state under the action of the elastic deformation force of itself.

The buckle structure that this embodiment provided carries out the lock with pin 1 and box 2 through the cooperation of buckle 12 with buckle groove 22, and simple structure can increase of service life, promotes reliability and reduce cost.

The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
