[0024] An embodiment of the present utility model provides a wall-mounted display screen rear shell. Refer to Figure 1 and Figure 2 , which includes a front frame 2 and a back plate 3. The front frame 2 and the back plate 3 together form a receiving cavity for installing the control main board 7;

[0025] An installation groove 31 communicating with the accommodating cavity is formed in the back plate 3, and a cable inlet channel is provided in the installation groove 31.

[0026] This embodiment improves the cable installation structure of the rear case of the existing wall-mounted display screen. That is, an installation groove 31 is formed in the back plate 3, and a cable inlet channel is provided in the installation groove 31. The cable can be connected to the control main board 7 located in the accommodating cavity through the cable inlet channel. Specifically, the front frame 2 and the back plate 3 are fixedly connected to form a hollow accommodating cavity. The control main board 7 is installed in the accommodating cavity and fixedly connected to the front frame 2. The installation groove 31 on the back plate 3 is arranged along the control main board 7, that is, the installation groove 31 is an L-shaped installation groove, which is convenient for the connection between the cable and the interface of the control main board. An opening communicating with the accommodating cavity is provided between the installation groove 31 on the back plate 3 and the accommodating cavity. At this time, the interface of the control main board 7 is located at the opening. The cable enters from the cable inlet channel and is connected to the interface of the control main board 7 in the installation groove 31. Since the cable enters from the cable inlet channel and is connected to the interface of the control main board 7 in the installation groove 31, the wall-mounted display screen equipped with the rear case of the wall-mounted display screen of the present application can be closely attached to the wall, and the cable will not be exposed outside, thereby preventing the cable from being damaged due to external extrusion or touch and reducing the damage to the cable itself. In addition, since the cable is not exposed outside, it also has an aesthetic effect.

[0027] It should be noted that in other embodiments, a detachable cover plate 1 is provided on the installation groove 31. The cover plate 1 is connected to the installation groove 31 by means of snap, screw or magnetic attraction, etc. The cover plate 1 can effectively block the installation groove 31 to prevent external impurities such as dust and moisture from entering the installation groove 31, thereby protecting the cable from pollution and corrosion, and further improving the aesthetics of the product.

[0028] Furthermore, referring to Figure 2 The cable inlet channel includes a first cable inlet channel 321 and a second cable inlet channel 322. The first cable inlet channel 321 is arranged on the left side of the installation groove 31, and the second cable inlet channel 322 is arranged on the right side of the installation groove 31. In this embodiment, cable protection members are provided at the first cable inlet channel 321 and the second cable inlet channel 322. The cable protection members are installed at the cable inlet channel by means of screws or snaps, etc. The cable protection members can better avoid external damage to the cable by providing a layer of buffering and isolation, and the cable protection members can help to sort and fix the cable so that it passes through the cable inlet channel orderly, improving the cleanliness and aesthetics of the device. Specifically, the form and material of the cable protection members can be selected according to actual needs. A sleeve or sheath made of a soft material such as rubber or plastic can be used to wrap the cable, or a fixing frame or guiding groove made of metal or hard plastic can be used to fix and guide the cable.

[0029] The cable entry channel further includes a third cable entry channel, which is the opening of the installation groove 31, that is, the third cable entry channel is a part of the installation groove 31, allowing the cable to directly penetrate into the installation groove 31 from the outside of the wall and be connected to the interface of the control main board 7.

[0030] It should be noted that in other embodiments, the cable entry channel may further include a fourth cable entry channel, which may be provided below the installation groove 31. By providing cable entry channels at different positions, the layout requirements of the cables can be better adapted.

[0031] Furthermore, a fixing member 4 is provided in the installation groove 31 near the cable entry channel for fixing the cable. The fixing member is fixedly installed in the installation groove by screws or other fastening devices. Fixing holes are provided on the fixing member. The cable enters the installation groove through the cable entry channel and then passes through the fixing holes, so that the cable is fixed in the installation groove and will not shift left and right, which can reduce the friction and extrusion of the cable in the installation groove 31, reduce the risk of cable damage, extend the service life of the cable, and contribute to subsequent maintenance and management, improving the overall aesthetics and work efficiency.

[0032] Furthermore, at least two first wall hanging holes 13 are provided on the back plate 3, and the rear case of the wall-mounted display screen can be hung on the wall through the first wall hanging holes 13. In this embodiment, the first wall hanging hole 13 has a first aperture and a second aperture, and the first aperture is larger than the second aperture. The wall-mounted display screen is hung on the wall by combining with the first wall hanging hole 13 by screws. It can be understood that the diameter of the screw head of the screw is larger than the second aperture and smaller than the first aperture. Thus, when the screw is locked to the wall, the rear case of the wall-mounted display screen will not fall off, and when disassembling, the screw is loosened, and the rear case of the wall-mounted display screen is moved downward, and the screw disengages from the first aperture of the rear case of the wall-mounted display screen.

[0033] Furthermore, referring to Figure 4, the rear case of the display screen further includes a wall mount 5. A wall mount groove 33 is provided on the back plate 3. The wall mount groove 33 is detachably connected to the wall mount 5. At least two second wall mount holes 14 are provided in the wall mount groove 33. At least two protruding wall mount rods corresponding to the at least two second wall mount holes 14 are provided on the wall mount 5. The at least two protruding wall mount rods are inserted into the at least two second wall mount holes 14 and fixed after moving along the L-shaped structure. In this embodiment, the second wall mount hole 14 is an L-shaped wall mount hole. The structure of the second wall mount hole 14 is similar to that of the first wall mount hole 13, that is, the second wall mount hole 14 has a third aperture and a fourth aperture, and the third aperture is larger than the fourth aperture. The wall mount 5 is fixed to the rear case of the wall-mounted display screen through the wall mount rod. The wall mount rod includes a wall mount head and a wall mount column. The wall mount head moves from the third aperture of the second wall mount hole 14 along the L-shaped structure to the fourth aperture, so that the rear case of the wall-mounted display screen is fixed to the wall mount 5. Then the wall mount 5 is fixed to the wall. It can be understood that the diameter of the wall mount head of the wall mount rod is larger than the fourth aperture and smaller than the third aperture, and is fixed to the third aperture after moving along the L-shaped structure, thereby ensuring the tight combination of the wall mount rod and the rear case, and the wall mount head is not easily detached from the second wall mount hole 14. And when disassembling, loosen the wall mount rod, move the rear case of the wall-mounted display screen laterally and then move it upward, so that the wall mount rod disengages from the fourth aperture of the rear case of the wall-mounted display screen.

[0034] It should be noted that the wall mount rod adopts a screw of the prior art in this embodiment, that is, the wall mount head is the head of the screw, and the wall mount column is the body of the screw. The head and the body of the screw are integrated, which enhances the overall strength and stability of the wall mount rod, making the installed wall mount rod more firm and reliable. And when the wall mount rod needs to be replaced or adjusted in position, the user only needs to use an appropriate tool to screw the screw out of the wall without damaging the wall.

[0035] A wall-mounted display device includes a display screen 6, a cover plate 1, an upper bracket 8, a lower bracket 9, a speaker 10, a signal lamp 12, an upper cover piece 11, and the above-mentioned rear case of the wall-mounted display screen.
