Description of the Invention: [Technical Field] The present invention relates to an electronic device, and more particularly to an electronic device having a lateral button structure. [Prior Art] In today's smart phones, thinning is often the focus of design. Further, in order to improve the appearance texture, a metal shell having a better gloss is often used. However, after the thickness of the body is thinned, the internal space is so narrow that it is difficult to form a large space on the side of the metal casing in a limited space to accommodate the button structure. Also, due to the narrow internal space, the conventional button structure is limited in the processing of the reverse hook assembly, and only a single structure can be used as a fixed elastic arm to provide appropriate flexible motion for the user to press in one direction. If the stroke of pressing the action is not enough, the touch of the button will be poor. SUMMARY OF THE INVENTION The present invention is directed to an electronic device having a lateral button structure having a two-way button and an easy assembly function to overcome the problem of narrow assembly space. According to an aspect of the invention, an electronic device having a lateral button structure is proposed. The electronic device includes a metal housing, a button body and a positioning tip. The metal housing has a side button area. The button body is disposed in the lateral button area. The button body includes a first pressing portion, a second pressing portion and a lever. A point is provided in the center of the lever, and the lever is connected between the first pressing portion and the second pressing portion to make the first pressing portion and the second pressing portion oscillate with respect to the fulcrum. The bottom of the positioning tip is fixed to the lateral button area, and the top of the positioning tip passes through the fulcrum-perforation to fix the fulcrum on the lateral button area. In order to better understand the above and other aspects of the present invention, the following description of the preferred embodiments and the accompanying drawings will be described in detail as follows: [Embodiment] The lateral button structure of the embodiment and the application thereof The electronic device uses the two-way button to set the si*, and arranges the button body and the positioning tip in the lateral button area to form a side button structure. Therefore, when the fulcrum of the button body is assembled on the positioning tip, both ends of the button body can be rotated relative to the fulcrum to input the respective pressing apostrophes, thereby achieving the non-linked two-way button function. In addition, a cushioning space is formed in the perforation of the fulcrum to move the fulcrum relative to the cocking position, thereby increasing the cushioning stroke when the pressing is performed. 1A and 1B are respectively an exploded perspective view and an assembled view of a side button structure according to an embodiment. Figure lc is a cross-sectional view showing the lateral button structure in accordance with an embodiment. Referring first to Figures 1A and 1B, the lateral button structure 1A includes a button body 100 and a positioning tip 14〇. The button body 1 is disposed on one of the lateral button regions 162 of the metal body 16. The button body 1A includes a first pressing portion 110, a second pressing portion 12A, and a lever 13b. A point 132 is provided in the center of the lever 13〇. The lever 13 is coupled between the first pressing portion 11A and the second pressing portion 120 to swing the first pressing portion 11A and the second pressing portion 120 with respect to the fulcrum 132. The bottom of the positioning tip "o" is fixed to the lateral button area 162, and the top of the positioning tip 14" is worn by one of the fulcrums 132.

Referring to FIG. 1A, the positioning tip 140 includes a rod 142, a flange 144, and a fixing portion 146. The rod 142 is located within the perforation 132a. A flange 144 is provided at one end of the rod body 142 and protrudes from the side edge of the rod body 142. The fixing portion 146 is disposed at the other end of the rod body 142 to fix the bottom of the positioning tip 140 to the side button region 62. In the embodiment, the positioning tip 14 埋 buryes the fixing portion 146 in a recess 162a of the lateral button region 162, for example, in a splicing manner to form a riveted structure, as shown in Fig. 1C. The positioning tip 140 is made of, for example, a metal material, and the rod body 142, the flange 144 and the fixing portion 146 are integrally formed, for example, in a machined manner, so that the positioning tip 14 turns into a convex-shaped structure. In assembly, the positioning tip 14 is pressed against the upper edge of the fixing portion 146 by, for example, a pressing tool, and the solid 疋 146 is embedded in the metal housing 16 by metal extrusion deformation to make the positioning tip. "o is joined to the metal casing 16a. In addition, in FIG. 1A, when the fulcrum 132 of the button body 1 褒 is placed on the cocking tip 140, the flange 144 and the fulcrum at the top of the locating tip 140 A pre-clamping between the perforations 132a of 132 is followed by a positive force to the fulcrum 132 to overcome the engagement force between the flange 144 and the fulcrum 132 such that the flange 144 passes through the perforations 132a and the fulcrum 132 is snapped Between the 144 spot fixing portions 146. Thus, the top of the positioning tip 140 can be limited to the fulcrum 132, as shown in Figures 1B and 1C. In addition, in Figure 1B, the first pressing portion 11〇 The second pressing portion 120 and the fulcrum 130 protrude from one side of the lever 130, and the other side of the lever 13〇 is exposed in the groove 162b of one of the lateral button regions 162 as a force applying portion 134. In the embodiment, the perforation 132a of the fulcrum 132 is, for example, 201243895. A long hole or an elliptical hole having a long axis L, located at a force In the direction, a buffer space is formed in the through hole 132a to move the fulcrum 132 and the positioning portion 140. When one end (the A end or the B end) of the button body 100 is stressed, the lever 13 is rotated by the fulcrum 132. Outside the angle, the fulcrum 132 can also be moved along the long axis L (the direction of the force application) by at least one distance until the fulcrum 132 abuts against the inner wall of the groove 162b. Therefore, the fulcrum 132 can be moved relative to the positioning tip 140 to increase the pressing.

In addition, the electronic device 20 further includes a circuit board 17 disposed on the metal body 16. The circuit board 17 includes a first electrode spring 172 and a first electrode spring 174. The first electrode elastic piece 172 abuts against the first pressing portion 11A: to receive the first pressing signal. The second electrode tab 74 abuts the second pressing P 120 for receiving the second pressing signal. In one embodiment, the perforations 132a of the fulcrum 132 are, for example, a long hole or an elliptical hole. Therefore, when the first electrode shrapnel m receives the first pressing signal, the lever 130 is rotated by the fulcrum 132 by the first angle ' and the fulcrum 132 is biased relative to the positioning tip 140. 6 201243895

In addition, when the second electrode spring 174 receives the second pressing signal, the lever 130 is reversely rotated by a second angle by the fulcrum 132, and the fulcrum 132 is moved by at least one distance relative to the positioning tip 140 in the biasing direction. Thus, the fulcrum 132 can be moved relative to the locating tip 140 to increase the cushioning stroke of the push. Next, please refer to FIGS. 3 and 4, wherein FIG. 4 is a partial schematic view of the electronic device according to an embodiment. The electronic device 20 further includes an outer casing 18 covering the metal casing 16 to form a recess 162b in the lateral button region 162, and the recess 162b for receiving the button body 100. In an embodiment, the recess 162b is located, for example, at the exit of the horn. Since the exit of La 0-8 is designed to have a large accommodation space and its thickness is relatively thick, it is suitable for placing a lateral button structure that can be pressed by the user. 10 ° In the fourth figure, the outer casing The side of the 18 is provided with a baffle 182 located on the bottom surface of the recess 162b. The sound insulating plate 182 is connected between the metal casing 16 and the outer casing 18 and has a sound hole 182a.
