[0026] Embodiment 1:

[0027] Reference Figure 1 and Figure 3 As shown, a new type of wall-mounted electric lifting bracket includes an outer frame 1, a push rod motor 2 is arranged on the outer frame 1, a main body is arranged at the output end of the push rod motor 2, the main body includes a left lifting frame 3, a middle lifting frame 4 and a right lifting frame 5 arranged in sequence, a main positioning plate 6 is arranged inside the middle lifting frame 4, auxiliary positioning plates 7 are arranged on both sides of the main positioning plate 6, and positioning holes 8 are arranged on the main positioning plate 6 and the auxiliary positioning plate 7; including a mounting plate 9, the mounting plate 9 is fixed to the positioning plate through the positioning hole 8.

[0028] When in use, the device to be displayed is mounted on the main body using the mounting plate 9. Due to the numerous positioning holes 8 and the supporting function of the left lifting frame 3 and the right lifting frame 5 extending on both sides, it can be applied to a variety of display devices, including but not limited to smart blackboards, various LCD screens (including LED splicing screens), interactive electronic whiteboards of various sizes, writing boards, projection screens (hard screens), etc.

[0029] After the installation is completed, the push rod motor 2 is used to drive the main body to move up and down to complete the up and down movement of the display device.

[0030] An upper connecting plate 10 and a lower connecting plate 11 are arranged between the middle lifting frame 4 and the left lifting frame 3 and the right lifting frame 5 on both sides; a reinforcing plate 12 is arranged at the center position of the left lifting frame 3 and the right lifting frame 5 to enhance the stability of the structure; a track pulley assembly 13 is arranged on the side of the left lifting frame 3 and the right lifting frame 5 to reduce resistance during lifting.

[0031] First fixing plates 14 are arranged at intervals on both sides of the outer frame 1. The first fixing plates 14 are provided with mounting holes 15. When installed on a solid wall, the outer frame 1 can be fixed to the solid wall directly by drilling holes with screws; auxiliary fixing plates 19 are arranged on both sides of the bottom of the middle lifting frame 4.

[0032] Embodiment 2:

[0033] Reference Figure 2As shown, the difference from the first embodiment is that the first fixing plates 14 and the mounting holes 15 are not provided on both sides of the outer frame 1, but two additional columns 16 are included. The columns 16 are fixed by upper fixing plates 17 and lower fixing plates 18 respectively. The outer frame 1 is fixed between the two columns 16. When encountering a hollow wall, directly punching the wall cannot provide a stable support effect like a solid wall. Therefore, the columns 16 are used to first fix the columns 16 by the upper fixing plates 17 and the lower fixing plates 18, and then the outer frame 1 is installed between the two fixed columns 16. At this time, it does not matter whether the wall is solid or hollow, and the fixing effect of the outer frame 1 and the body can be achieved.

[0034] Embodiment three:

[0035] Reference Figure 4 and Figure 5 As shown, the difference from the first embodiment is that an extension frame 20 is provided on the top of the middle lifting frame 4, and a projector mounting frame 21 is provided on the extension frame 20. The projector mounting frame 21 is retractable and rotatable within a range. By installing the projector on the projector mounting frame 21, the angle of the projector and the distance between the projector and the main body can be changed. The height position of the projector can be adjusted by using a push rod motor according to the adjustment method of the first embodiment.

[0036] The above-described embodiments are only preferred embodiments for fully illustrating the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or changes made by technicians in the technical field on the basis of the present utility model are all within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the claims.
