[0043] The structure of the screen projection device in one embodiment is described in detail below with reference to the accompanying drawings. Figures 1 to 4As shown, in this embodiment, the screen projection device includes a switch assembly, a button assembly, a housing 8 and a cable 9. The cable 9 includes a first connection end 91 and a second connection end 92. The first connection end 91 is connected to the switch assembly, and the second connection end 92 can be connected to a mobile phone, a computer terminal, etc. The figure exemplarily shows that the second connection end 92 is provided with a USB interface, but the present application is not limited to this. The switch assembly includes a switch circuit board 71, a control switch 72 and a cover plate 6. The switch circuit board 71 is provided with main circuit modules for realizing the screen projection function. For example, the switch circuit board 71 is provided with a first communication module that communicates with the cable 9, a second communication module that transmits wireless signals to the outside, etc. The switch circuit board 71 is used to send multimedia data received from the terminal through the cable 9 to another display screen through wireless signals. The switch circuit board 71 is fixed to the housing 8 by a second fixing member 22, and the control switch 72 is fixed to the first side surface of the switch circuit board 71 (with a Figure 4 For example, the first side of the switch circuit board 71 is the lower side of the switch circuit board 71, and the first side surface of the switch circuit board 71 is the lower surface of the switch circuit board 71), and the control switch 72 is electrically connected to the switch circuit board 71. The first connection end 91 of the cable 9 is electrically connected to the switch circuit board 71. The cover plate 6 is located on the first side of the switch circuit board 71, and the cover plate 6 is fixed to the housing 8 by a third fixing member 23. An opening 63 is provided at the center of the cover plate 6, and the control switch 72 is inserted into the opening 63 and protrudes downward from the cover plate 6. The cover plate 6 can protect the electronic components on the surface of the switch circuit board 71.

[0044] The button assembly includes a button plate 4 and an elastic member 5. The button plate 4 is located on a first side of the cover plate 6 (with a Figure 4 For example, the first side of the cover plate 6 is the lower side of the cover plate 6, the button plate 4 is located below the cover plate 6, and is located below the switch circuit board 71, the cover plate 6 is arranged between the button plate 4 and the switch circuit board 71, and the control switch 72 protrudes from the cover plate 6 toward the button plate 4. The button plate 4 includes a pressing portion 44 and a shell matching portion 43, and the pressing portion 44 is movably mounted on the shell 8 through the shell matching portion 43, as shown in FIG. Figure 4As shown, the pressing portion 44 of the button plate 4 can move up and down relative to the shell 8. The elastic member 5 is supported between the button plate 4 and the cover plate 6, so that the switch circuit board 71 can move between a first position away from the pressing portion 44 and a second position close to the pressing portion 44. In this projection device, the switch assembly and the button assembly are separately provided, and an elastic member 5 is provided between the switch assembly and the button plate 4, and one of the switch circuit board 71 and the pressing portion 44 is relatively fixed to the shell 8. The shell mating portion 43 is two arc-shaped portions provided on the outside of the pressing portion 44, and the shell mating portion 43 is fixedly connected to the shell 8 and can undergo a certain elastic deformation under force. As shown Figure 4 As shown, in the initial state where the housing 8 is not subjected to force, under the biasing force of the elastic member 5, the pressing portion 44 is located below the control switch 72, but no pressing force is applied to the control switch 72, the control switch 72 is not turned on, and the screen projection function is not turned on. When the user presses the housing 8 downward, the housing 8 drives the switch circuit board 71 to move downward relative to the pressing portion 44, and the compression elastic member 5 and the housing matching portion 43 are elastically deformed, so that there is relative movement between the switch circuit board 71 and the pressing portion 44, and the pressing portion 44 presses the control switch 72, so that the control switch 72 is pressed upward and turned on, and the control switch 72 sends a screen projection start signal to the switch circuit board 71, thereby enabling the screen projection function through the switch circuit board 71. The present application provides a whole-surface press switch control structure, which has no limitation on the position where the user presses the housing 8, and the screen projection switch control can be achieved by pressing in any direction of the housing 8, which is convenient for the user to operate.

[0045] like Figure 3 and Figure 4 As shown, the switch assembly is at least partially accommodated inside the housing 8. The second fixing member 22 is, for example, a metric screw, and the third fixing member 23 is, for example, a self-tapping screw, but the present application is not limited thereto, and the use of other fixing members to achieve the fixation of the switch circuit board 71, the cover plate 6 and the housing 8 also falls within the scope of protection of the present application. A first mating opening 711 is provided on one side of the switch circuit board 71, a second mating opening 81 is provided on the side wall of the housing 8, and a second mating portion 62 is provided on the cover plate 6.

The counterweight 3 is in the shape of a thin plate, and its surface is in contact with the bottom surface of the button plate 4. The foot pad 1 is in the shape of a circular ring, which cushions and supports the bottom surface of the projection device. Specifically, the button plate 4 is provided with an outer edge 42 extending in a direction away from the switch assembly, and the counterweight 3 and the foot pad 1 are arranged on the inner side of the outer edge 42 of the button plate 4.

[0047] When assembling the projection device, first fix the switch circuit board 71 to the outer shell 8 with the second fixing member 22, and then install the cable 9 so that the first connection end 91 of the cable 9 is located at the first matching port 711 of the switch circuit board 71 and the second matching port 81 of the outer shell 8, and then fix the cover plate 6 to the outer shell 8 through the second fixing member 22 to press the first connection end 91 of the cable 9. Then, bond the counterweight 3 and one side of the button plate 4, fix the elastic member 5 to the other side of the button plate 4, and use the first fixing member 21 to install the outer shell matching part 43 on the outer shell 8. This first fixing member 21 is, for example, a self-tapping screw, but the present application is not limited to this. Finally, stick the foot pad 1 on the counterweight 3 to complete the assembly of the projection device.

[0048] like Figure 3 As shown, the elastic member 5 includes a mounting portion 51 and at least one elastic arm 52, one end of the elastic arm 52 is connected to the mounting portion 51, and the other end forms a supporting end. The mounting portion 51 is fixed to the button plate 4, and the supporting end of the elastic arm 52 is supported on the cover plate 6. Figure 4 As shown, when the housing 8 is not subjected to external force, the projection device is in an initial state. At this time, under the biasing force of the elastic member 5, there is a certain gap between the pressing portion 44 and the cover plate 6, and the switch circuit board 71 is in a first position away from the pressing portion 44, and the pressing portion 44 does not apply force to the control switch 72. In this embodiment, the mounting portion 51 is an annular or circular structure, and the elastic member 5 includes a plurality of elastic arms 52, and the plurality of elastic arms 52 are evenly distributed along the circumference of the mounting portion 51, so that the elastic support effect of the elastic member 5 on the cover plate 6 is more evenly distributed, and the gap between the cover plate 6 and the button plate 4 is more evenly distributed in all directions in the initial state.

[0049] In another alternative embodiment, the mounting portion 51 may be fixed to the cover plate 6, and the abutting end of the elastic arm 52 may be supported on the button plate 4, so as to achieve the purpose of elastic support between the cover plate 6 and the button plate 4. The elastic member 5 may also adopt other elastic structures, not limited to those described here.

[0050] In this embodiment, at least one buckle 41 is provided on the side of the button plate 4, and the buckle 41 includes a guide portion and a hook portion located at the end of the guide portion, and a first matching portion 61 matching with the buckle 41 is provided on the side of the cover plate 6. Optionally, the buckle 41 is provided in plurality and evenly distributed along the circumference of the button plate 4. Specifically, the first matching portion 61 is a recess formed on the side of the cover plate 6, the guide portion is at least partially located inside the recess, and the hook portion can clamp the inner side of the recess. Through the cooperation between the buckle 41 and the cover plate 6, while realizing the movable connection between the button plate 4 and the cover plate 6, the button plate 4 is effectively prevented from being partially disengaged from the housing 8, thereby maintaining the structural stability of the projection device structure during use.

[0051] In the above embodiment, the switch circuit board 71 of the switch assembly is fixed to the housing 8, and the pressing portion 44 of the button board 4 can move up and down relative to the housing 8. By pressing the housing 8, the pressing portion 44 can press the control switch 72 in the switch assembly to achieve screen projection control. In another alternative embodiment, the button board in the button assembly can also be fixed to the housing as a whole, so that the switch circuit board at least partially drives the control switch to move up and down relative to the housing. The button board is arranged above the switch assembly. When the housing is pressed, the housing drives the button board to move downward relative to the switch assembly, and the button board presses the control switch downward, which can also achieve the purpose of triggering the control switch by pressing the housing in any direction, and also falls within the protection scope of this application.

[0052] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions.
