Description

Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device that enhances the aesthetic appearance by an internal structural design.

Thanks to the development of technology, the use of portable electronic devices (eg, a portable communication device, tablet) has become very popular. In portable electronic devices, a battery is typically included to provide the power required by the portable electronic device.

When the battery is exhausted, the user opens the battery cover on the back of the portable electronic device to remove the battery. At this time, the user must open the battery cover by the finger button on the side of the battery cover. However, the design of the buckle will destroy the visual aesthetic of the portable electronic device, which is inconsistent with the current design trend.

It is an object of the present invention to provide an electronic device that utilizes an innovative mechanism design to simplify the structure of the electronic device to increase the visual aesthetic of the electronic device.

To achieve the above objective, the present invention provides an electronic device comprising: a main circuit board, a button circuit board, a button, an abutting member and a cover. The button circuit board is electrically connected to the main circuit board in a manner movable relative to the main circuit board, wherein the button circuit board includes a first surface and a second surface opposite to the first surface. The button faces the first side of the button circuit board. The abutting member is coupled to the second side of the button circuit board. The cover is attached to the abutment. When the button moves to a first position, the button circuit board emits a signal. When the button moves from the first position to the second position, the button drives the button circuit board and the abutting member to move together, and presses the cover plate.

Since the button of the present invention is connected to the button circuit board and the cover plate, when the user presses the button, not only can a predetermined command be given, but also the purpose of removing the cover plate can be completed. In this way, the purpose of simplifying the appearance of the electronic device can be achieved, and the aesthetics of the electronic device can be improved.

A perforation 138. The second portion 153b is coupled to the first portion 153a and passes through the second through hole 139, wherein the second portion 153b is coupled to the card slot 143 of the back plate 140.

The operation of the electronic device 100 of the present invention is described as follows: Please refer to Figures 5, 6, and 7. 5 is a cross-sectional view showing the electronic device 100 of the present invention in a use state; FIG. 6 is a cross-sectional view showing the button 120 of the electronic device 100 of the present invention in a first position; and FIG. 7 is a view showing the electronic device 100 of the present invention. A cross-sectional view of the button 120 when it is in the second position.

In one embodiment, button 120 is a function button. When the user applies the button 120 to command an external force, the button 120 moves toward the button circuit board 130 to a first position (Fig. 6). At this time, the bump 123 of the button 120 is deformed against the support member 180, and the button circuit board 170 receives the command external force from the support member 180, and sends an electronic signal to the central processing unit of the main circuit board 175 (not shown). To perform an established step. If the user stops applying the external force to the button 120, the support member 180 will provide a restoring force to return the button 120 to the original position (Fig. 5).

It should be noted that, as described above, the extended length of the convex key 125 is greater than the extended length of the convex block 123. When the button 120 is in the first position (Fig. 6), the convex key 125 of the key 120 will happen to abut the key circuit board. The first side of 170 is 171. Therefore, when the user wishes to separate the cover 140 from the rear cover 130, the user can apply the button 120 to decompose the external force by one of the external forces. The external force of the disassembly is simultaneously transmitted to the button circuit board 170 by the bump 123 and the support member 180 and the protruding key 125, so that the button 120, the abutting member 150, and the button circuit board 170 are simultaneously moved toward the rear cover 130. At this time, the elastic member 160 is simultaneously compressed by the external force of the decomposition.

As shown in Fig. 7, when the abutment member 150 is moved toward the rear cover 130, the abutting member 150 will be pressed by the projection 137 of the rear cover 130 to cause the second portion 153b of the extension arm 153 to be self-covered from the cover plate 140. The groove 143 is detached. On the other hand, as the abutment member 150 moves in the direction of the rear cover 130, the curved portion of the first portion 153a of the extension arm 153 presses the projection 141 of the cover plate 140 downward to disengage the cover plate 140 from the rear cover 130.

Similarly, when the user stops applying a disassembling external force, the self-restoring force of the elastic member 160 causes the button 120, the abutting member 150, the button circuit board 170, and the support member 180 to simultaneously move toward the front cover 110 (6th). Figure). At the same time, the support member 180 also returns the button 120 to the original position due to its own restoring force (Fig. 5).

It is to be noted that, in the above embodiment, the disassembling external force is simultaneously transmitted to the key circuit board 170 by the bump 123 and the support member 180 and the convex key 125, but is not limited thereto. The external force of the decomposition can also be transmitted to the key circuit board 170 by the bump 123 and the support member 180. However, in order to prevent the user from applying excessive decomposition external force of the button 120 to cause permanent deformation of the support member 180, the convex key 125 is then disposed on the bottom surface of the button 120. In detail, when the user applies the excessive external force of the button 120, the protruding key 125 will provide the decomposed external force of the button circuit board 170 in preference to the bump 123 and the support member 180, so that the button 120, the abutting member 150, and the button The circuit board 170 is simultaneously moved toward the rear cover 130. In one embodiment, the command external force is 1.6N, and the above-mentioned decomposition external force is 2.0N, but is not limited thereto.

In the electronic device of the present invention, since the button is connected to the button circuit board and is connected to the cover plate, when the user applies different force paths, different purposes can be achieved. Therefore, in the prior art, the finger buckle designed to open the battery cover can be simplified, and the visual beauty of the electronic device can be improved.

Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the present invention, and it is possible to make some modifications and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
