Detailed implementation mode

[0026] The above embodiments only describe the preferred implementation modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary engineering and technical personnel in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.

[0027] As Figure 1 shown, a single-column TV lifting bracket includes: a base assembly 10, an electric lifting column 20, and a hanger assembly 30. Among them, the electric lifting column 20 is fixed on the base assembly 10, and the hanger assembly 30 is fixedly connected to the top of the electric lifting column 20. The LCD TV is fixedly installed on the hanger assembly 30, and the height of the LCD TV can be adjusted by adjusting the height of the electric lifting column 20. In addition, a number of casters with brakes are installed on the lower side of the base assembly 10 for easy movement.

[0028] As Figure 2 shown, the electric lifting column 20 includes an outer tube assembly 21, an inner tube assembly 22 sleeved inside the outer tube assembly 21, a linear drive assembly 23, and a motor 24 fixed on the outer tube assembly 21. The linear drive assembly 23 includes a transmission gearbox 231 fixed to the tube wall of the outer tube assembly 21, a nut 232 fixed to the top of the inner tube assembly 22, and a lead screw 233 screwed to the nut 232. The motor 24 and the transmission gearbox 231 transmit torque through a transmission rod. There is a pair of bevel gears in the transmission gearbox 231, and the bevel gears can drive the lead screw 233 to rotate. The bevel gears can also be designed as face gears or bevel gears, which mainly play the role of changing the torque transmission direction and decelerating. Since the lead screw 233 is screwed to the nut 232, when the lead screw 233 rotates, it can drive the nut 232 to linearly move along the axial direction of the lead screw. Therefore, by controlling the forward and reverse rotation of the motor 24 through the controller, the electric lifting column 20 can be driven to linearly expand and contract, and the height of the hanger assembly 30 can be adjusted.

[0029] As Figure 3As shown, the base assembly 10 includes a right longitudinal beam 11, a left longitudinal beam 12 and a cross beam 13 which are detachably connected. Moreover, the left longitudinal beam 12 and the right longitudinal beam 11 form a certain angle, and the front opening is slightly larger than the rear. The connection of the cross beam 13 with the left longitudinal beam 12 and the right longitudinal beam 11 is also towards the rear. Its main function is to make the center of gravity of the LCD TV exactly fall at the center formed by the four casters of the left longitudinal beam 12 and the right longitudinal beam 11, making the entire TV bracket more stable.

[0030] An installation seat 11a is welded on the right longitudinal beam 11, and installation seats are also welded at symmetrical positions on the left longitudinal beam 12. After the installation seats are inserted into the cross beam 13, the three are fixedly connected by fasteners. The advantage of the assembled design of the base assembly 10 is to reduce the packaging volume, with low transportation cost and not easily damaged during transportation.

[0031] More preferably, the installation seat 11a is a pipe and is provided with installation threaded holes. The threaded holes can be processed by hot melt drilling or by using rivet nuts.

[0032] As Figure 4 shown, a tray 25 is also provided on the electric lifting column 20. A controller can be set on the tray 25, or small office supplies can be placed, such as: LCD TV controller, signal receiver, Bluetooth speaker, marker pen, etc.

[0033] On the outer tube assembly 21 of the electric lifting column 20, a U-shaped part is welded to form a socket 21a on the outer tube assembly 21. A L-shaped plug 251 is also fixedly connected to the bottom of the tray 25. After inserting the plug 251 into the socket 21a, tighten the fastening screws to easily fix the tray 25 on the electric lifting column 20. Similarly, loosen the screws and the tray 25 can also be easily removed.

[0034] As Figure 5 shown, a motor cover 26 is also provided outside the motor 24. The motor cover 26 not only reduces the mechanical safety risk brought by the transmission of the motor 24, but also can reduce the motor noise and improve the aesthetic appearance of the product. Preferably, wire management posts 26a are also provided on both sides of the motor cover 26, and the too-long wire harnesses can be stored on both sides of the motor cover 26, reducing the exposure of the messy wire harnesses and further improving the aesthetic appearance of the entire product.

[0035] The motor cover 26 can be fixed on the outer tube assembly 21 by screws or snap fasteners. Preferably, as Figure 5 shown, the motor cover 26 is provided with a snap 26b, and the outer tube assembly 21 is provided with a notch 21b adapted to the snap 26b. The motor cover 26 is installed on the outer tube assembly 21 by snapping the snap 26b into the notch 21b.

[0036] Preferably, a slot is formed in the upper part of the electric lifting column 20, and an embedded socket 27 can be placed in the slot. The socket 27 can supply power to the electric lifting column 20 or to the LCD TV.
