[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figures 1 to 7The double-column same-drive TV lifting bracket shown in the figure includes: a mounting panel 1, a storage table 2, a first column 3 and a second column 4; the first column 3 and the second column 4 are symmetrically arranged, each including an outer tube 31 and an inner tube 32 slidably arranged inside the outer tube 31, the mounting panel 1 is arranged between the two inner tubes 32, and the opposite sides of the two inner tubes 32 are provided with a groove 321 for the mounting panel 1 to be embedded, and the storage table 2 is arranged between the two outer tubes 31; wherein, a synchronous drive component 5 is arranged under the storage table 2, and the synchronous drive component 5 includes a drive motor 51, an intermediate transmission rod 52 and two screw nut groups 53 arranged at both ends of the intermediate transmission rod 52; the two screw nut groups 53 are correspondingly arranged in the two outer tubes 31, and are connected to the intermediate transmission rod 52 through a first gear box 6, and the drive motor 51 is connected to the intermediate transmission rod 52 through a second gear box 7. In the preferred embodiment, a hand controller is provided at the storage table 2, and the drive motor 51 can be controlled by the hand controller to enable the two inner tubes 32 to be raised and lowered to the corresponding memory height according to different usage environments, thereby improving the convenience of use.

[0040] The utility model increases the overall stability of the structure and reduces the risk of tilting through the double-column design, and the synchronous drive component 5 can ensure that the two columns are raised and lowered at the same time, avoiding tilting or damage caused by asynchronous lifting, and the mounting panel 1 is installed through the groove 321, which is not easy to fall off accidentally, and makes the center of gravity of the TV closer to the center of the bracket, further improving stability.

[0041] In this solution, the storage platform 2 includes a support base 21 and a tabletop 22 fixed to the top of the support base 21. The support base 21 has a U-shaped structure and, together with the tabletop 22, forms a mounting space within which the intermediate drive rod 52 and the drive motor 51 are mounted. The U-shaped support base 21 provides a compact mounting location for the intermediate drive rod 52 and the drive motor 51, providing protection and extending the life of the device.

[0042] Furthermore, to facilitate disassembly of the bracket and reduce transportation costs, a first auxiliary mounting member 8 and a second auxiliary mounting member 9 are provided on opposite sides of the two outer tubes 31, respectively, and are located at the same height. The two ends of the support base 21 are connected to the two outer tubes 31 via the first auxiliary mounting member 8 and the second auxiliary mounting member 9. The outer tubes 31 are detachably mounted on the two auxiliary mounting members via bolts, improving adaptability. In addition, the first auxiliary mounting member 8 and the second auxiliary mounting member 9 are welded to the outer tubes 31. The two auxiliary mounting members can more evenly distribute the load on the U-shaped support base 21 to the two outer tubes 31, reducing stress at a single connection point and reducing the risk of structural damage or collapse.

[0043] On the basis of the above embodiment, the first auxiliary mounting part 8 and the second auxiliary mounting part 9 each include at least two positioning plates, which are embedded in the inner cavity of the support seat 21 and fit with the side wall of the inner cavity; wherein, the side edge of the positioning plate on one side of the second auxiliary mounting part 9 extends toward the first auxiliary mounting part 8, and is bent at the extended end to form a third auxiliary mounting part 10, and the drive motor 51 is fixed on the third auxiliary mounting part 10. The positioning plates are embedded in the inner cavity of the support seat 21 and fit with the side wall, which can ensure the precise position of the auxiliary mounting parts and ensure structural stability. By extending and bending the third auxiliary mounting part 10 on the second auxiliary mounting part 9, space can be used more effectively, providing a suitable installation position for the drive motor 51. This hidden installation can keep the appearance of the bracket neat and beautiful, and avoid the clutter caused by the exposure of components such as the motor.

[0044] Since there is a gap between the inner tube 32 and the outer tube 31 , a guide sleeve is provided at the end of the outer tube 31 where the inner tube 32 extends, thereby effectively preventing the inner tube 32 from tilting and getting stuck during the extension and retraction process.

[0045] In the preferred embodiment of the present invention, a fixing base 11 is provided at the bottom of the first gearbox 6, and the fixing base 11 is fixed to the inside of the outer tube 31 by bolts. The combination of the fixing base 11 and the outer tube 31 improves the rigidity of the entire gear transmission system and reduces errors caused by movement or vibration of the gearbox.

[0046] In the preferred embodiment, a mounting plate 12 is provided at the end of the inner tube 32 extending into the outer tube 31. The mounting plate 12 is connected to the nut of the screw nut group 53 to drive the inner tube 32 to rise and fall. The screw nut group 53 can accurately control the position of the inner tube 32 and has a self-locking function, which can maintain the position of the inner tube 32 unchanged in the absence of power, avoiding sliding due to gravity or other external forces.

[0047] In order to reduce the overall weight of the mounting panel 1, during the design process, the panels and tubes used in the mounting panel 1 are all lightweight. Since the tubes are hollow, when the sides of the mounting panel 1 are locked and positioned by the columns, in order to ensure the stability and reliability of the connection, preferably, the mounting panel 1 includes an upper side beam, a lower side beam, and an intermediate support plate located in the same vertical plane, with the ends of the upper and lower side beams protruding from the ends of the intermediate support plate to form a placement space; locking blocks 1a are provided at both ends of the intermediate support plate, with the middle protruding portion of the locking block 1a embedded in the placement space and fixed to the intermediate support plate by bolts; the two ends of the locking block 1a extend outward to form two blocking plates 1b, which abut the ends of the upper and lower side beams and are fixed to the inner tube 32 by bolts. The design of the locking block 1a and the blocking plate 1b can ensure that the TV is firmly mounted on the bracket, reducing the risk of accidental detachment, and the end face gap formed by the intermediate support plate and the two side beams helps to improve the heat dissipation conditions at the back of the TV.

[0048] In the preferred embodiment of the present invention, the first and second columns 3 and 4 are provided with legs 33 at their bases, and universal wheels are provided on the legs 33. The universal wheels allow the TV lift bracket to be easily moved, allowing the user to easily adjust the bracket's position as needed, facilitating positioning of the TV in the optimal viewing area, thereby improving the maneuverability and flexibility of the entire device.

[0049] Specifically, the leg 33 comprises a frame and a cover 333 disposed outside the frame. The frame comprises a main support beam 331 and positioning supports 332 symmetrically disposed on either side of the main support beam 331. The universal wheel assembly is fixed to the main support beam 331. The two positioning supports 332 are disposed corresponding to the outer tube 31, embedded in the inner cavity of the outer tube 31, and fixedly connected by bolts. A clearance groove 311 is provided at one end of the outer tube 31 near the main support beam 331 for the main support beam 331 to fit into. The detachable structure allows the leg 33 to be disassembled when not in use, reducing the space occupied during transportation and storage. During use, the cover 333 protects the frame from impact, scratches, and corrosion, extending the service life of the leg 33. The main support beam 331, serving as the primary load-bearing structure of the leg 333, is embedded in the inner cavity of the outer tube 31 by the positioning supports 332 and fixed by bolts, simplifying the installation process and improving installation efficiency. This concealed fixing method creates a neater appearance and enhances the aesthetics.
