[0042] The middle part of the multifunctional panel is provided with a horizontal circular button opening and four track-shaped button openings. The track-shaped openings are surrounded by mounting columns 104, and the mounting columns are provided with button fixing screw holes.

[0043] Circular socket holes 103 are respectively arranged on both sides of the lower area of ​​the panel, and mounting columns 104 are arranged around the socket holes. Screw holes for fixing the socket fixing plate are arranged in the mounting columns 104.

[0044] The button assembly includes a button strip 105 made of an elastic material and a button strip pressing plate 106 .

[0045] The button strip 105 is provided with buttons 107 having the same number as the button openings.

[0046] A cylindrical boss 108 is provided on the back side of the button 107 .

[0047] After all buttons have passed through the button openings, the button strip pressing plate 106 is fixed to the back of the multi-function panel by screws 109 and washers 110 .

[0048] The socket assembly includes two socket fixing plates 111 .

[0052] Using a socket fixing plate to fix the socket can make the multifunctional panel be used for various types of sockets, such as American, European, Japanese, etc. When adapting to sockets in various countries, only the socket and the socket fixing plate need to be replaced to achieve compatibility, thereby reducing the production cost of the product.

[0053] The socket fixing plate includes a first fixing piece and a second fixing piece. The first fixing piece is provided with four screw holes on both sides of the top and the bottom. The second fixing piece is provided with three screw holes on both sides of the top and the bottom.

[0054] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0055] In this embodiment, the screw holes of the second fixing member all protrude from the second fixing member edge 115. In other embodiments, the screw holes of the first fixing member all protrude from the edge of the first fixing member.

[0056] One of the two socket holes is installed with a DC socket 112 , and the other is installed with an AC socket 113 .

[0057] The AC socket and the DC socket can be fixed to the AC socket fixing plate and the DC socket fixing plate respectively by screws, and the AC socket fixing plate and the DC socket fixing plate are further fixed to the multi-function panel by screws.

[0058] Since sockets of different specifications and manufacturers have certain differences in appearance and installation dimensions, when changing the socket specifications, it is only necessary to replace different installation fixing plates at the same time, without replacing the entire multi-function panel, thus reducing the cost of the product.

[0059] The AC socket cover and the DC socket cover are both made of elastic material, and their installation dimensions match the openings on the multi-function panel, and their shapes match the AC socket and the DC socket respectively. After being installed in place, they can not only play a waterproof role and meet safety requirements, but also play an indicating role through the logo thereon, and have a certain aesthetic effect.

[0060] In this embodiment, one socket fixing plate has four screw holes for fixing to the multi-function panel, and the other has three screw holes for fixing to the multi-function panel. One screw hole of the socket fixing plate protrudes from the edge of the fixing plate.

[0061] This design is designed to accommodate a wider variety of socket styles. Some sockets are relatively large, and the protruding screw holes can provide more area to accommodate the sockets.

[0062] The button strip comprises button strip panels having the same number as the button openings.

[0063] Adjacent button strip panels are connected via connecting pieces.

[0064] The connector is integrally formed with the button strip panel.

[0065] The width of the button strip panel is greater than the width of the connector.

[0066] The button strip pressing plate fixes the button strip on the back side of the multifunctional panel by pressing the button strip panel.

[0067] The multifunctional panel is provided with a plurality of button fixing screw holes.

[0068] After all buttons pass through the button openings, the button fixing screw holes are located between adjacent button strip panels.

[0069] The number of button openings is 5, and the button in the middle is a round power on / off button.

[0070] The shape of the button bar panel at one end of the button bar is different from the shapes of other button bar panels except the button bar panel of the power on / off button.

[0071] The inner side of the multifunctional panel is provided with a protrusion 116 matching the shape of the button strip panel at one end.

[0072] The protruding piece cooperates with the button strip panel at one end to form a fool-proof structure.

[0073] The button strip is made of elastic material and is in the shape of a long strip. There is a round raised button in the middle of the front and two track-shaped raised buttons on each side. There are small cylindrical bosses on the back of the five raised buttons for triggering the keys on the circuit board.

[0074] The outer contour of the button bar pressure plate is similar to that of the button bar. The raised position of the button bar corresponds to the button opening of the multi-function panel. The opening area is larger than the corresponding raised area of ​​the front side of the button bar and smaller than the outer edge area of ​​the button bar.

[0075] The protrusion on the front side of the button strip can be assembled into the button opening of the multifunctional panel.

[0076] The button strip pressure plate is placed on the button strip, and the two are pressed tightly on the multifunctional panel by screws and washers.

[0077] Since the button strip is made of an elastic material, when the raised button on the front of the button strip is pressed hard, the pressed raised area deforms backwards, and the small boss behind the raised area also moves backwards, which can trigger the electrical switches of various functions arranged behind the button strip. After the pressure is removed, the button strip returns to a free state.

[0078] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principle and essence of the present invention, but these changes and modifications fall within the protection scope of the present invention.
