The embodiment of the present invention provides a side key assembly 10 of a mobile terminal. The side key assembly 10 includes a side key 12 and a fixed support frame 11 for fixing in the housing 20 of the mobile terminal. The fixed support frame 11 is fixed. There is a through hole 112 which is fitted on the side key 12. The side wall of the through hole 112 has at least one elastic pressing piece 111. When the side key 12 passes through the through hole 112, the elastic pressing piece 111 is pressed against the side wall of the side key 12. .

In the above embodiment, the position of the side key 12 is defined by the elastic pressing piece 111 on the fixed support frame 11 provided, thereby reducing the sway of the side key 12 on the assembly to the mobile terminal, and at the same time, the fixed support frame 11 is disposed through The elastic pressing piece 111 defines the side key 12 at a set position, avoiding the side key 12 from being scratched to the flexible circuit board when swaying, improving the safety of the flexible circuit board, and fixing the side key 12 together with the fixed support frame 11. On the housing of the mobile terminal, the side keys 12 are conveniently assembled to the mobile terminal, which improves the assembly efficiency of the mobile terminal.

In order to facilitate the understanding of the structure and principle of the side key assembly 10 of the mobile terminal provided by the embodiment of the present invention, a detailed description will be given below in conjunction with a specific embodiment.

It should be noted that the side key assembly 10 provided in this embodiment is applied to a mobile terminal, and the mobile terminal includes a housing 20, and the housing 20 is provided with a side key 12 hole that cooperates with the side key 12. When the side key assembly 10 is mounted on the mobile terminal, the side keys 12 of the side key assembly 10 are exposed through the side key 12 holes. And the mobile terminal can be a common mobile terminal such as a mobile phone or a tablet computer.

As shown in FIG. 1 , FIG. 2 a - 2b and FIG. 3 , the side key assembly 10 in this embodiment includes a fixed support frame 11 and side keys 12 , wherein the fixed support frame 11 is connected to the housing 20 of the mobile terminal, and It is fixed inside the casing 20 in specific use to support the side keys 12. The fixing bracket is provided with a through hole 112, and at least one elastic pressing piece 111 is disposed on the side wall of the through hole 112. The elastic pressing piece 111 presses the side key 12 when the side key 12 passes through the through hole 112, so that the side key 12 is pressed. The side key 12 is pressed. When the side key assembly 10 is assembled in the mobile terminal, the side key assembly 10 is fixed in the housing 20, and the side key 12 is exposed through the side key 12 of the mobile terminal, after the assembly is completed. The elastic pressing piece 111 presses the side key 12 by the limit pressing action of the elastic pressing piece 111, so that the side key 12 has been restricted by the self structure of the side key assembly 10 before the assembly, so that the side key 12 is made. The situation in which the side key 12 is shaken due to the influence of the assembly error is avoided, the use effect of the side key 12 is improved, and at the same time, since the side key 12 is limited before assembly, the installation of the side key 12 is facilitated, and the installation is improved. Entire move Terminal installation efficiency.

In a specific arrangement, the elastic pressing piece 111 in the side key assembly 10 may be one or more. In a specific arrangement, the elastic pressing piece 111 may be used to press the side key 12 toward one side, or to press the side key 12 on multiple sides.

As shown in FIG. 3, in one specific embodiment, the number of the elastic pressing pieces 111 is one or more, and the elastic pressing piece 111 is disposed on one side of the through hole 112, and the side is the length of the through hole 112. The side wall, and the plurality of elastic pressing pieces 111 press the side keys 12 toward the same side. In specific use, the plurality of elastic pressing pieces 111 press the side keys 12 to the long side walls of the through holes 112 where the elastic pressing piece 111 is not disposed. In the above, the position of the side key 12 is defined by the elastic pressing piece 111 and the long side wall. When assembling to the mobile terminal, the long side wall passing through the hole of the side key 12 may be common to the elastic pressing piece 111 according to the actual assembly condition. The sway of the side key 12 is defined, or the long side wall of the through hole 112 and the elastic pressing piece 111 together define the sway of the side key 12. By the above limitation, it can be seen that the elasticity of the fixing frame 11 is fixed when an assembly error occurs. The pressing piece 111 can well define the shaking of the side key 12. Avoid the effects of assembly errors on the side keys 12. Further, in a preferred embodiment, the elastic pressing piece 111 does not press the side key 12 to the side wall of the side key 12 or the side wall of the through hole 112 when the side key 12 is pressed, and the side key 12 passes through the rubber connected thereto. The elastic force of the button provides a reverse supporting force to achieve the sway of the side key 12 by the elastic pressing piece 111 and the rubber button. When the above structure is employed, the side keys 12 are not in contact with the through holes 112 and the side walls of the side keys 12, thereby improving the hand feeling of the side keys 12 when pressed.

As shown in FIG. 4, in another specific embodiment, the elastic pressing piece 111 is plural, and the plurality of elastic pressing pieces 111 are arranged on the two long side walls of the through hole 112, in a specific embodiment. The plurality of elastic pressing pieces 111 are symmetrically disposed on both sides of the through hole 112, and the pressing directions thereof are opposite. When the side key 12 is mounted in the fixed supporting frame 11, the elastic pressing piece 111 is pressed from the opposite two directions. The key 12 is such that the side key 12 avoids shaking. In the specific installation, since the elastic pressing piece 111 of the side key 12 is disposed to define the position, it can be conveniently installed in the hole of the side key 12. Moreover, when such a structure is adopted, the size of the hole of the side key 12 can have a large tolerance, thereby reducing the processing difficulty of the housing 20, and also avoiding the influence of machining errors, thereby improving the processing of the mobile terminal. effectiveness.

In the above specific embodiment, the elastic pressing piece 111 is disposed in the through hole in an inclined manner. The elastic pressing piece 111 on the side wall of the 112 is an elastic pressing piece 111 which is inclined toward the side of the through hole 112. The slanting arrangement improves the restoring force of the elastic pressing piece 111. When the side key 12 passes through the through hole 112, the elastic pressing piece 111 can be pressed well, so that the elastic pressing piece 111 can provide a large pressing. Force to prevent the side button 12 from shaking.
