Pressing the button body includes a plurality of cantilevers. The end of the plurality of cantilevers is fixed to the mounting frame, so that the button cover and the button body are mounted on the mounting frame, and a gap is formed between the button body and the circuit board, so that the button body has a certain pressing The spears are aligned with the triggering pieces. In use, the button body is moved toward the triggering elastic piece by the stretching elastic force Hn to press the triggering elastic piece ^ and the corresponding rebounding action. However, the thin button assembly adopts the mounting mechanism, and the assembly frame is located outside the gap, so that the overall thickness of the thin button is large, and in order to ensure a certain amount of feel, the length of the arm usually needs to be longer and more The relative size of the thin button assembly is increased. SUMMARY OF THE INVENTION In view of this, it is necessary to provide a button assembly of a small size. It is also necessary to provide - Wei set noodle county Chi-like carrying (four) electronic devices. 3 201042687 Two kinds of button components 'including - button cover, - button body, - circuit board and a solid '~ bracket on the circuit board' are provided with a plurality of triggering elastic pieces, which are combined with the button body In one piece, the button body and the triggering piece of the circuit board are provided. The bracket comprises a plurality of supporting columns connected to each other, the button body is connected to the supporting column, and the supporting column is abutted between the cantilever and the circuit board. Used to isolate teeth from each other. 5x pingyue is a portable electronic device, which is provided with a button component, the button component comprises a button cover, a button body, a circuit board and a ridge on the circuit board, and the circuit board is arranged There is a plurality of triggering elastic pieces, and the key cover is combined with the key body to be "body". The key body is aligned with the triggering elastic piece of the circuit board, and the supporting frame includes a plurality of branches connected to each other, and the supporting piece is supported on the support column. Selecting a column between the cantilever and the circuit board 'is used to isolate the triggering pieces from each other. * Compared with the prior art, the bracket of the present invention is located between the button body and the circuit board, thereby reducing the vertical circuit of the button assembly. [Embodiment] The button assembly of the present invention is suitable for mobile electronic devices such as mobile phones and personal handheld computers. Please refer to Sun 1 and Figure 2. The button assembly 1 includes a plurality of button covers u and a button. The body 12, the circuit board 13 and the bracket 14. The button cover u is integrated with the button body 12. The button body 12 is coupled to the bracket 14 and aligned with the circuit board. Can be rectangular, round The other shape is used for the direct contact pressing of the operator. The button cover u includes a plurality of first button cover m and a second button cover 112, and the plurality of first button covers ms are disposed around the second button cover 112. The fourth 201042687 = The button cover 112 is a multi-directional button cover. The first button cover ηι and the second button | 112 are printed with a button mark such as a character, a number or a symbol. The button cover u is made of polycarbonate material (Polycarbonate, PC) is manufactured by an injection molding method. The face 12 is substantially a rectangular plate-shaped body. The button body 12 includes an upper surface 121 and a lower surface 122 opposite to the upper wire 121. The upper surface i2i has In the embodiment, the button cover u can be fixed on the mounting portion 1211 of the button body. The lower surface corresponds to the mounting portion of the button body. A plurality of pressing columns 1221 ′ are formed on the mi protrusions. A plurality of cantilevers 123 are formed between the pressing columns 1221. The pressing columns 1221 are used to press the circuit board 13. One side of the pressing columns 1221 is provided with a light guiding surface 1222. a cantilever 123 is fixed to the bracket 14 so as to The key cover ^ and the button body are mounted on the bracket 14. The thickness of the cantilever 123 is much smaller than the thickness of the pressing column 1221. The cantilever 123 has a certain deformation ability, and the elastic deformation can automatically return to the original shape, thereby driving The pressing column 1221 is restored to the original position. The circuit board 13 is provided with a plurality of arc-shaped triggering elastic pieces 131, and a light source 132 is disposed adjacent to each of the triggering elastic pieces 131. In the embodiment, the light source 132 is a light emitting device. A light emitting diode (LED), each of the button bodies 12 is aligned with the triggering elastic piece 131 and spaced apart from the triggering elastic piece 131 by a distance. The bracket 14 is substantially a frame body, and a plurality of accommodating grooves 141' are formed in the corresponding mounting portions to form the support posts 142 disposed around the accommodating grooves 141 and connected to each other. The bracket 14 is disposed between the lower surface 122 of the button body 12 and the circuit board 13 , wherein each of the receiving slots 141 is correspondingly disposed in a pair of pressing columns 1221 , a triggering elastic piece 131 and a light source 132 . The support post 142 is abutted between the cantilever 123 and the circuit board 13, and the pressing column 1221 and the triggering spring 5201042687 piece 131 and the light source 132 and the other pair β are placed on the pressing column 122; [Isolated from the triggering shrapnel 131 and the light source 131. The bracket 14 is made of a material that is opaque and elastically deformable. In the present embodiment, the side bracket 14 is made of foam. When the armor is mounted, the button cover 11 is first fixed on the button body 12; then the bracket 14 is fixed on the circuit board 13, and each of the receiving slots 141 receives a triggering elastic piece 131 and a corresponding light source. 132 is disposed therein, and each light guiding surface 1222 is directed to a corresponding one of the light sources 132; finally, the cantilever 123 of the corresponding button body 12 is fixed to the supporting column 142 of the bracket 14. Since the accommodating groove 141 disposes the light source 132 therein, the light leakage intensity between the button covers 11 is weakened, and by providing the light guiding surface 1222, the light emitted from the light source 132 can be directed to the 111th or The other side of the second button cover 112 opposite to the light source 132 is such that the entire first button cover 111 or the second button cover 112 has a uniform light. When in use, the cantilever 123 of the button body 12 of the button cover u is elastically stretched, so that the corresponding pressing column 122 of the button body 12 faces the triggering piece m of the circuit board 13 Travel until the press column assists
