DETAILED DESCRIPTION

[0035] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the wall-mounted display screen of the present utility model. The panel assembly of the present utility model is not limited to the description of the following embodiments.

[0036] This embodiment provides a wall-mounted display screen, which can be used to control a smart home system, or independently control a certain smart home device. It can also be a display screen that can play multimedia. The wall-mounted display screen is generally installed on a wall.

[0037] like Figure 1-5 As shown, this embodiment provides a wall-mounted display screen. Specifically, the wall-mounted display screen is a wall-mounted central control screen for controlling a smart home system. The wall-mounted display screen includes: a display screen body 1, a female head component 2, and a base component 3; the female head component 2 includes a female head shield 21 and a second circuit board 22 arranged on the female head shield 21 facing the side of the display screen body 1, the second circuit board 22 is provided with a female head quick connector 23 facing the base component 3, and the second circuit board 22 is connected to the main circuit board (not shown in the figure) in the display screen body 1 through an electrical wire; The base assembly 3 includes a base 31 and a first circuit board 32 arranged in a first inner cavity 310 of the base 31, the first circuit board 32 is provided with a wiring terminal 321 for connecting to the mains, the first circuit board 32 is provided with a male quick connector 33 facing the female quick connector 23, and the first circuit board 32 is electrically connected through the female quick connector 23 and the male quick connector 33; the female shield 21 is connected to the display screen body 1 through a first connecting structure, and the base 31 and the female shield 21 are connected through a second detachable connecting structure.

[0038] In this embodiment, the base 31 is usually installed in the slot on the wall, and the base 31 is provided with a first circuit board 32, and the first circuit board 32 is provided with a wiring terminal 321, which can be connected to the main power line to realize the basic power supply function of the base component 3. The female head component 2 is first connected to the display screen body 1, and then connected to the base 31 through the second detachable connection structure, so that the display screen 1 can be quickly connected to the base 31 on the wall. In addition, a quick electrical connection is also achieved through the female head quick connector 23 and the male head quick connector 33. Compared with the previous display screen installation method, both the installation of the display screen and the connection of the line are faster and simpler.

[0039] In this embodiment, the female quick connector 23 and the male quick connector 33 can be USB interfaces, such as Type-C connectors. Of course, other quick connector structures can also be used. In this embodiment, the first circuit board 32 can also be provided with a communication module (such as a network interface). In addition to achieving electrical connection, communication connection can also be achieved through the Type-C connector.

[0040] In this embodiment, if Figure 5 and Figure 6 As shown, a first shield connection groove 11 is provided at the position where the display screen body 1 is connected to the female shield 21, and one side of the female shield 21 is inserted into the first shield connection groove 11. By setting the first shield connection groove 11, installation positioning can be achieved, and it is also more conducive to setting the first connection structure.

[0041] In this embodiment, if Figure 7 and Figure 8 As shown, the first connection structure includes a plurality of first buckles 111 arranged on the groove wall of the first shield connection groove 11 and a first clamping position 211 arranged on the peripheral wall of the female shield 21, and the female shield 21 is clamped into the first buckle 111 through the first clamping position 211 to form a quick connection with the display screen body 1. Among them, the limiting surfaces of the first buckle 111 and the first clamping position 211 are almost perpendicular to the insertion direction of the female shield 21, so that the female shield 21 can be strongly limited, and it is difficult for the female shield 21 to be separated from the display screen body 1.

[0042] Of course, the first connection structure may also be a connection in other ways. Since the disassembly process is mainly to ensure the separation of the display screen body 1 and the base assembly 3, and at the same time to ensure the reliability of the connection between the second circuit board 22 and the display screen body 1, the female head assembly 2 and the display screen body 1 can be a fixed, non-detachable connection or a difficult-to-detach connection that requires the aid of auxiliary tools, such as screw connection, ultrasonic welding, etc.

[0043] In this embodiment, a first limiting column 112 is further provided on the groove wall of the first shield connection groove 11, and a first limiting groove 212 is correspondingly provided on the peripheral wall of the female shield 21 to cooperate with it. The first limiting column 112 and the first limiting groove 212 are used to limit and cooperate to better achieve accurate insertion of the female shield 21. To ensure accurate insertion, the first limiting column 112 can be arranged in a non-centered and asymmetrical manner, so as to ensure correct insertion of the female shield 21.

[0044] Of course, the first limiting column 112 and the first limiting groove 212 are interchangeable, that is, the limiting groove can be set on the groove wall of the first shield connecting groove 11, and the limiting column can be set on the peripheral wall of the female head shield.

[0045] In this embodiment, the opening side of the female head shield 21 faces the display screen body 1, and the bottom wall 217 of the female head shield 21 faces the base assembly 3. A plurality of studs 213 are provided on the inner side of the bottom wall 217 for lifting the second circuit board 22. The bottom wall 217 is also provided with a second quick connector avoidance hole 218, and the top end of the female head quick connector 23 is limited in the second quick connector avoidance hole 218. The second circuit board 22 is lifted by the studs 213, thereby reserving an extension space for the female head quick connector 23, and the top end of the female head quick connector 23 is limited by the second quick connector avoidance hole 218, so that the structural protection of the female head quick connector 23 can be achieved, and the lateral force acting on the female head quick connector 23 can be avoided to cause damage to the circuit board connection, and the connection with the base assembly is more reliable.

[0046] In this embodiment, if Figure 5 and Fig. 9 As shown, a second shield connecting groove 311 is provided at the open end of the first inner cavity 310 of the base 31 , and the other side of the female shield 21 is inserted into the second shield connecting groove 311 .

[0047] Furthermore, the second detachable connection structure is a detachable quick connection structure. The second detachable connection structure includes a plurality of second buckles 314 arranged on the groove wall of the second shield connection groove 311 and a second clamping position 214 arranged on the peripheral wall of the female shield 21. The female shield 21 is clamped into the second buckle 314 through the second clamping position 214 to form a quick connection with the base 31. Different from the first buckle 111 and the first clamping position 211, the limiting surfaces of the second buckle 314 and the second clamping position 214 are inclined relative to the insertion direction, so that the connection strength between the female shield 21 and the base 31 is weaker than the connection strength with the display screen body 1, so that when the display screen body 1 is disassembled, the female shield 21 is separated from the base 31 but not from the display screen body 1, ensuring the connection reliability between the second circuit board 22 and the display screen body 1.

[0048] In this embodiment, a second limiting column 313 is further provided on the groove wall of the second shield connecting groove 311, and a second limiting groove 215 is correspondingly provided on the peripheral wall of the female head shield 21 to cooperate with the second limiting column 313.

[0049] In this embodiment, a base cover plate 34 is provided in the first inner cavity 310 to separate the second shield connection groove 311 from the first circuit board 32, a plurality of cover plate support parts 336 are provided in the first inner cavity 310 to support the base cover plate 34, a third buckle 315 is provided on the inner peripheral wall of the first inner cavity 310, the base cover plate 34 is placed on the cover plate support part 336 and is fastened and fixed by the third buckle 315, and the base cover plate 34 is also provided with a first quick connector avoidance hole 341 to avoid the male quick connector 33. The first circuit board 32 can be isolated and protected by the base cover plate 34, thereby ensuring the safety of the first circuit board 32, and at the same time, the first circuit board 32 can be prevented from being taken out during disassembly.

[0050] In this embodiment, a positioning groove 12 is provided on the outer periphery of the display screen body 1 corresponding to the first shield connecting groove 11, and a protrusion 37 extending outward and adapted to the shape of the positioning groove 12 is provided at the open end of the base 31. When the base assembly 3 is connected to the display screen body 1 through the female head assembly 2, the protrusion 37 is inserted into the positioning groove 12 to form mutual limitation, so as to improve the docking accuracy of the display screen body 1 when it is connected, and each buckle and position are accurately connected.

[0051] The installation process of the wall-mounted display screen in this embodiment is as follows:

[0052] First, install the base cover 34 and the first circuit board 32 to the base 31; pass screws of corresponding sizes through the screw holes on the base 31 (not marked in the figure), and embed the base 31 into the preset installation slot on the wall, and then further install the connected display screen body 1 and the female head component 2 to the base 31; wherein, the first circuit board 32 passes through the type-C male head of the base cover 34 and just corresponds to the type-C female head on the female head component to achieve electrical connection and communication connection; the second buckle on the inner inner wall of the base 31 cavity is clamped to the second clamping position on the side outer surface of the female head shield 21 of the female head component 2, and is clamped to the second limiting groove on the side outer surface of the female head shield through the second limiting column on the inner inner wall of the base 31 cavity, thereby realizing the base limiting and fixing of the female head component; finally, the installation of the wall-mounted display screen is achieved.
