[0034] See also Figure 1 and Figure 2 In the embodiment of the present application, the multifunctional key panel includes a base 1 and a panel assembly 2 detachably mounted on the base 1, and the problem that the existing integrated control panel is not easy to disassemble is solved by this detachable connection method;

[0035] Specifically, the panel assembly 2 and the base 1 are connected by a detachable plug-in and snap-fit ​​method, please refer to Figure 2 and Figure 3 ,exist Figure 2 and Figure 3 In the illustrated embodiment, a connection groove 11 is provided on the base 1, and a plug-in portion 21 is provided on the panel assembly 2. The panel assembly 2 is plugged into the connection groove 11 of the base 1 through the plug-in portion 21, thereby realizing that the panel assembly 2 and the base 1 are fixed by plugging; preferably, a first groove 111 is provided on the inner wall of the connection groove 11, and at least one side of the plug-in portion 21 is provided with an elastic protrusion 211. In this way, when the plug-in portion 21 is inserted into the connection groove 11 and reaches a predetermined position, the elastic protrusion 211 will be engaged with the first groove 111, thereby realizing that the panel assembly 2 and the base 1 are fixed by buckling. The cooperation between the elastic protrusion 211 and the first groove 111 can strengthen the connection between the base 1 and the panel assembly 2, making the connection between the two more firm;

[0036] In this embodiment, the connection slot 11 and the plug-in portion 21 are further utilized. Figure 2 and Figure 3 A accommodating space is provided inside the base 1, and a first circuit board 12 is installed in the accommodating space, a first terminal 112 is provided in the connecting groove 11, and the first terminal 112 is electrically connected to the first circuit board 12, and a plug-in slot is provided in the plug-in portion 21, and the shape and size of the plug-in slot are designed for the first terminal 112, that is, the first terminal 112 can be accommodated, and a second terminal 212 is provided in the plug-in slot. When the plug-in portion 21 is plugged into the connecting groove 11, the first terminal 112 located in the connecting groove 11 will contact and conduct with the second terminal 212 in the plug-in slot, wherein the first terminal 112 and the second terminal 212 are defined as a male plug and a female plug, and the connection between the first terminal 112 and the second terminal 212 not only conducts the first circuit board 12 and the panel assembly 2, but also further strengthens the connection between the base 1 and the panel assembly 2.

[0037] It should be noted that the terms "first", "second", etc. in this document are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] exist Figure 7 In the illustrated embodiment, the panel assembly 2 includes: a connector 22, a second circuit board 23 and a button 24. The connector 22 and the button 24 are relatively arranged on both sides of the second circuit board 23. The above-mentioned plug-in portion 21 is connected to the connector 22. The second terminal 212 is only arranged in the plug-in slot. The second terminal 212 is actually connected to the second circuit board 23. That is, when the panel assembly 2 is not fully assembled, the plug-in slot on the plug-in portion 21 is actually a hole that penetrates the connector 22. After the panel assembly 2 is assembled, the second circuit board 23 is used as the bottom surface of the plug-in slot to form the so-called plug-in slot. The button 24 is buckled with the connector 22 and wraps the second circuit board 23 therein. In this embodiment, a touch switch 231 is usually designed on the second circuit board 23, that is, when the button 24 is pressed by the user, the touch switch 231 on the second circuit board 23 will be further triggered, so that the second circuit board 23 generates a corresponding signal and then outputs it to the first circuit board 12; of course, the present application is not limited to protecting the panel assembly 2 with a button 24, but is also applicable to panel assemblies 2 such as capacitive touch screens or resistive touch screens.

[0039] It should be noted that in the technical solution of the present application, the material of the plug-in portion 21 is an insulating and deformable plastic. In order to facilitate insertion into the connecting groove 11, the outer corners of the plug-in portion 21 are chamfered to form an inclined surface. As for the elastic protrusion 211 on the plug-in portion 21 (the plug-in portion 21 and the elastic protrusion 211 are integrally formed), the present application provides two different embodiments:

[0040] exist Figure 4 In the first embodiment shown, the elastic protrusion 211 is an isosceles triangle boss, and the first groove 111 matched with the elastic protrusion 211 is a square groove. At this time, the cross-sectional view of the elastic protrusion 211 is an isosceles triangle shape. When the plug-in portion 21 is inserted into the connecting groove 11, the top surface of the elastic protrusion 211 serves as an inclined surface to provide a certain degree of guidance, which facilitates the insertion of the plug-in portion 21 into the connecting groove 11. During the insertion process, the elastic protrusion 211 is squeezed inward by the inner wall of the connecting groove 11 (the squeezing will continue until the elastic protrusion 211 falls into the first groove 111). The plug-in portion 21 made of plastic supports it to undergo slight deformation. When the elastic protrusion 211 enters the first groove 111, the inclined surface of the elastic protrusion 211 abuts against the notch of the first groove 111; similarly, the bottom surface of the elastic protrusion 211 serves as an inclined surface to facilitate the plug-in portion 21 to be pulled out of the connecting groove 11.

[0041] exist Figure 5 In the second embodiment shown, the elastic protrusion 211 is a right-angled triangular boss, and the first groove 111 matched with the elastic protrusion 211 is a square groove. At this time, the cross-sectional view of the elastic protrusion 211 is in the shape of a right-angled triangle. In this embodiment, the matching between the elastic protrusion 211 and the first groove 111 is more secure than that of the first embodiment described above. In this embodiment, the plug-in portion 21 includes a plug-in portion body and a plug-in board 25. The plug-in portion body is provided with a notch to accommodate the plug-in board 25. The elastic protrusion 211 is arranged on the plug-in board 25. The material of the plug-in board 25 is the same as that of the plug-in portion body. The design of the plug-in board 25 enables the plug-in portion 21 to be inserted into the connecting groove 11, and the plug-in board 25 is supported by the connecting groove. 11 is squeezed and bent inwardly until the elastic protrusion 211 falls into the first groove 111; it should be noted that the plug-in body and the plug-in board 25 are both connected to the connecting member 22. Preferably, the connecting member 22 is provided with an opening 221, which is located on the outside of the plug-in board 25 and close to the plug-in board 25, and the second circuit board 23 does not cover the opening 221. In this way, when the plug-in part 21 needs to be pulled out, a paddle or a lever can be inserted into the opening 221 to enter the gap between the plug-in board 25 and the connecting groove 11. By pulling the paddle or the lever, the plug-in board 25 is bent and the elastic protrusion 211 is disengaged from the first groove 111, so that the plug-in part 21 is conveniently pulled out of the connecting groove 11. Further, as Figure 6As shown, a second groove 113 is provided on the inner wall of the connecting groove 11, the second groove 113 is connected to the outlet of the connecting groove 11 and the second groove 113 is opposite to the opening 221, and the second groove 113 is provided to facilitate the entry of a paddle or a lever; different from the first embodiment mentioned above, when the panel assembly 2 is disassembled from the base 1, it is necessary to first remove the button 24 from the connecting member 22 (the button 24 and the connecting member 22 have a snap-fit ​​structure and are detachably fastened), at this time, the second circuit board 23 can be pulled out to separate the second terminal 212 on the second circuit board 23 from the first terminal 112, and then the connecting member 22 and the base 1 can be disassembled (refer to the above-mentioned disassembly using a paddle or a lever).

[0042] In the present application, since the plug-in portion 21 is arranged around the second terminal 212, that is, the plug-in portion 21 not only serves as a connecting structure, when the multi-function button panel has not yet been assembled, that is, during the production or transportation process, the plug-in portion 21 on the panel assembly 2 can actually also protect the second terminal 212 to prevent the second terminal 212 from being damaged by bumps during the production or transportation process. For example, when the user's panel assembly 2 is damaged, a new panel assembly 2 needs to be mailed for replacement. During transportation, the plug-in portion 21 can protect the second terminal 212; similarly, the connecting groove 11 can also protect the first terminal 112.

[0043] See also Figure 2 In some embodiments, a connection terminal 121 is provided on the base, and the connection terminal 121 is electrically connected to the first circuit board 12. The connection terminal 121 is a USB interface. The uninstalled multi-function button panel can be connected to an external debugging device through the USB interface. The multi-function button panel can be detected or debugged through the debugging device.

[0044] See also Figure 7 and Figure 8 In some embodiments, the button 24 is provided with a display area 241. Specifically, the display area 241 is a translucent font engraved by laser. A backlight 232 is electrically connected to the second circuit board 23 and matches the display area 241. The display area 241 is illuminated by the backlight 232. Preferably, the light color of the backlight 232 is white or yellow. Compared with lights of other colors, white or yellow light looks softer and more comfortable.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
