In order to make the objects, technical solutions and advantageous technical effects of the present invention more clearly understood, the present invention is further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration only and not by way of limitation.

It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It should be further understood that the term "and/or" as used in the specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

The embodiment of the utility model provides an in, provide a side key fixed knot constructs 100 for install the side key such as power key, volume key, fingerprint touch key in mobile terminal's side, guarantee that the touch of side key is pressed and is felt the uniformity. The mobile terminal includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, and a digital camera.

As shown in fig. 1 and 2, the side key fixing structure 100 includes a key 10, a housing 20, and a switch assembly 30 fixed in the housing 20. In the example of the present embodiment, the key 10 is a side fingerprint touch key, and the switch element 30 is a switch key element. The switch assembly 30 is a rectangular parallelepiped.

The housing 20 is opened with a pressing hole 21. The pressing hole 21 may be a rectangular hole, an elliptical hole, or the like. Specifically, the housing 20 includes an outer plate 22 and a fixing plate 23 extending inward from a predetermined position inside the outer plate 22. The fixing plate 23 is vertically provided on the outer plate 22. The switch assembly 30 is fixed to a side of the fixing plate 23 away from the outer plate 22 such that the switch assembly 30 is spaced in parallel with the outer plate 22.

The key 10 is a silicone key or a rubber key, has a certain elasticity, and includes a connecting portion 11, and a pressing portion 12 and a pair of elastic arms 13 respectively disposed at two sides of the connecting portion 11. In the present embodiment, the connecting portion 11 has a rectangular sheet shape, has an area larger than that of the pressing hole 21, abuts against the fixing plate 23 and is disposed between the outer plate 22 and the switch assembly 30, so as to prevent the whole key 10 from falling off from the housing 20 through the pressing hole 21. Furthermore, the edge of the connecting part 11 is also provided with a limiting part 14. The stopper 14 abuts against the inner wall of the housing 20, thereby stopping the position of the key 10 in the housing 20 and preventing the connecting portion 11 from moving in the housing 20.

The cross section of the pressing portion 12 may be rectangular, oval, etc., and the shape and size thereof are matched with the pressing hole 21. When the connecting portion 11 abuts against the inside of the housing 20, the pressing portion 12 extends out of the housing 20 through the pressing hole 21 to form a protrusion, which is convenient for a user to touch and press.

The pair of elastic arms 13 are disposed at an interval and are respectively abutted to the predetermined position of the switch assembly 30, that is, the pair of elastic arms 13 are respectively disposed at two ends of the same side of the connecting portion 11 and then abutted to the predetermined position of the switch assembly 30. Therefore, the connecting portion 11 is spaced apart from the switch assembly 30 at a position between the pair of elastic arms 13, and the pressing portion 12 is located at a position between the connecting portion 11 and the pair of elastic arms 13 and away from the switch assembly 30, so that when the pressing portion 12 is touched and pressed, the connecting portion 11 is deformed and pressed down at a position between the pair of elastic arms 13, and the switch assembly 30 is touched and pressed, thereby completing the operation of the switch assembly 30.

Furthermore, the connecting portion 11 is further provided with a pressing block 15 at a side close to the switch assembly 30. The pressing piece 15 is arranged between the pair of elastic arms 13 and has a height relative to the surface of the connecting part 11 smaller than that of the elastic arms 13 relative to the surface of the connecting part 11, so that the stroke of the connecting part 11 when the switch assembly 30 is touched and pressed can be reduced.

In the embodiment of the present invention, the surface of the elastic arm 13 away from the connecting portion 11 is a cambered surface. That is, the contact of the elastic arm 13 with the surface of the switch assembly 30 is a point contact or a line contact. For example, if the surface of the side of the elastic arm 13 away from the connecting portion 11 is a hemisphere, the contact surface of the elastic arm 13 and the switch assembly 30 is a point of the elastic arm 13; if the elastic arm 13 is semi-cylindrical and the vertical surface is attached to the surface of the connecting portion 11, the contact surface between the elastic arm 13 and the switch assembly 30 is the line contact parallel to the central axis on the elastic arm 13.

When the user presses connecting portion 11 through pressing portion 12, connecting portion 11 is sunken along the direction that is close to switch module 30, this moment because the surface of elastic arm 13 is the cambered surface, thereby make elastic arm 13 can adapt to connecting portion 11 through the position that changes point contact or line contact, thereby avoid appearing pressing portion 12 obvious skew to appear in the bulge in the casing 20 outside, the button touch has been guaranteed to press and has felt the uniformity, at this moment, a pair of elastic arm 13 can be as connecting portion 11's support and provide elasticity and make connecting portion 11 resume to initial condition, press in-process elastic arm 13 not have casing 20 to pull, the elasticity is effectual, it is not crooked also to guarantee simultaneously to press portion 12. And traditional cube elastic arm, the button can make when pressing to press more arduous because of the perk of cube elastic arm one end, and is unfavorable for the button to resume initial condition.

In this embodiment, the elastic arm 13 is further provided with a through hole 16 coaxially disposed, so that the cross section of the elastic arm 13 is a semicircular ring, that is, the cross section of the elastic arm 13 is a semicircular ring or a circular ring-like closed loop arc. Wherein, the thickness of the elastic arm 13 is 0.25 mm-0.4 mm, thereby reducing the material cost.

The utility model also provides a mobile terminal, include as above any one of embodiment the side key fixed knot construct 100.

To sum up, the utility model provides a side key fixed knot constructs 100 and mobile terminal is the cambered surface setting through keeping away from the surface of connecting portion 11 one side with elastic arm 13 for become point contact or line contact from traditional face contact between elastic arm 13 and the switch module 30, thereby when two elastic arm 13 have the difference in height, adaptation and the switch module 30's contact point that elastic arm 13's cambered surface can the self-adaptation, and then can be obvious eliminate because of elastic arm 13's difference in height leads to pressing the crooked harmful effects of splenium 12, guaranteed to press the splenium 12 touch to press the uniformity of feeling.

The invention is not limited solely to that described in the specification and the embodiments, and additional advantages and modifications will readily occur to those skilled in the art, and it is not intended to be limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
