[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments.

[0035] As Figures 1 to 6 shown: a double-column lifting assembly, comprising:

[0036] The cross beam 11 is horizontally arranged.

[0037] Two lifting columns 12 are fixedly arranged at the two ends of the length direction of the cross beam 11, and the lifting column 12 comprises a vertical cavity, a lifting device is arranged in the vertical cavity, and the top end of the lifting column 12 is a lifting end.

[0038] Two bottom feet 13 are fixedly arranged at the bottom ends of the two lifting columns 12 for supporting.

[0039] The double-column design can effectively share the weight of the TV, making the center of gravity more balanced during lifting. This design is more resistant to tilting than a single-column structure, especially when the TV is large and heavy, ensuring the stability of the overall structure during lifting. Each lifting column 12 is equipped with a lifting device that can be lifted smoothly through a vertical cavity and a synchronous control mechanism. This structural design ensures that both columns are lifted simultaneously, avoiding the imbalance caused by asymmetric lifting.

[0040] In this embodiment, the lifting device comprises:

[0041] A brushless motor 121 is provided at the bottom of the vertical cavity.

[0042] A transmission screw rod 122 is in transmission connection with the brushless motor 121 and is driven to rotate by the brushless motor 121 driver. The transmission screw rod 122 is vertically arranged at the top of the brushless motor 121.

[0043] A hollow inner tube 123 is arranged in the vertical cavity and includes a screw nut 124. The screw nut 124 is sleeved on the transmission screw rod 122, and the top end of the transmission screw rod 122 is at least partially located in the hollow inner tube 123. When the transmission screw rod 122 rotates, it drives the hollow inner tube 123 to lift.

[0044] The brushless motor 121 as a power source has the characteristics of high efficiency, low noise, and long service life. It can drive the transmission screw rod 122 to rotate and achieve precise lifting movement. The transmission screw rod 122 converts the rotary motion of the brushless motor 121 into linear motion to drive the hollow inner tube 123 to lift, making the lifting action more stable and accurate, avoiding the shaking or jamming phenomenon in traditional systems. The long service life and high efficiency of the brushless motor 121 reduce maintenance requirements and improve the durability of the system. The hollow inner tube 123 cooperates with the transmission screw rod 122 through the screw nut 124 and realizes lifting with the rotation of the screw rod.

[0045] The outer wall of the hollow inner tube 123 is provided with a sliding sheet 1231, which rubs against the inner wall of the lifting column 12 during lifting of the hollow inner tube 123.

[0046] The sliding sheet 1231 on the outer wall of the inner tube contacts the inner wall of the column during lifting and produces moderate friction, which helps to reduce lateral shaking and enhance the stability of the lifting motion, avoiding unstable lifting caused by structural shaking. The sliding sheet 1231 design effectively prolongs the service life of the component and reduces the risk of wear during equipment use.

[0047] As a preferred embodiment of the above, the top of the hollow inner tube 123 is provided with a sealing cap 1232.

[0048] The sealing 1232 is designed to prevent dust and debris from entering the hollow inner tube 123 or the transmission system, protecting the internal mechanism. This improves the reliability of the device, reduces malfunctions caused by foreign matter entering, and reduces maintenance frequency while improving aesthetics.

[0049] In this embodiment, the top of the lifting column 12 is provided with an anti-swing ring 125, which limits the lifting of the hollow inner tube 123 and restricts its swinging.

[0050] The anti-swing ring 125 limits the lifting of the hollow inner tube 123 and effectively restricts its lateral swinging, maintaining the verticality of the lifting motion and improving the overall stability of the lifting system. This is particularly evident when carrying large-sized televisions, reducing mechanical wear caused by lateral swinging and further extending the service life of the components.

[0051] The bottom foot 13 includes two support legs 131, which are symmetrically arranged about the plane formed by the cross beam 11 and the lifting column 12, and the bottom of each support leg 131 is provided with a walking wheel 132.

[0052] The two support legs 131 are symmetrically distributed, providing a wider support surface and further improving the stability of the structure. The addition of the walking wheel 132 allows the device to be easily moved, facilitating position adjustment. The design of the support leg 131 effectively disperses the weight of the bracket, improving the anti-overturning ability. The walking wheel 132 improves the portability of the device, making it easy to use in different scenarios, especially in conference rooms, classrooms, and other places where frequent position adjustment is required.

[0053] Through the design of the sliding sheet 1231, anti-swing ring 125, and support leg 131, the shaking and lateral swinging during lifting are effectively reduced, ensuring that the television remains stable during lifting. The cooperation of the brushless motor 121 and transmission screw 122 provides efficient and precise lifting motion, while reducing the common wear and tear problems in traditional lifting systems. The design of the walking wheel 132 provides convenience for the movement of the device, while the stability of the support leg 131 ensures that the device can be placed stably after moving. The addition of the sealing 1232 and sliding sheet 1231 effectively prevents dust and protects the device, reducing the maintenance requirements and extending the service life of the system.

[0054] As shown in Figures 7 to 8 The present embodiment also includes a television stand, which comprises a double-column lifting assembly 1 as described above, and a television fixing assembly 2 arranged at the top of the double-column lifting assembly 1.

[0055] In this embodiment, the television fixing assembly 2 comprises:

[0056] Two fixed arms 21 are horizontally arranged at the top of the double-column lifting assembly 1.

[0057] Two hanging arms 22 are vertically hung on two fixed arms 21 respectively, and the distance between the two hanging arms 22 is adjustably arranged.

[0058] Two fixed arms 21 are horizontally arranged at the top of the double-column lifting assembly 1 to provide a basic support for fixing the television, and two hanging arms 22 are vertically hung on the fixed arms 21, and the distance between the two hanging arms 22 can be adjusted according to the width of the television, and the secure fixing of the television is realized through the mounting holes 221 at the distal end of the hanging arms 22.

[0059] The adjustable design between the two hanging arms 22 and the diversity of the mounting holes 221 enable the support to adapt to various sizes and installation requirements of the television, covering a wide range of applications from home to commercial scenarios.

[0060] The hanging arm 22 further comprises a lock catch 222, which locks the hanging arm 22 when the hanging arm 22 is hung on the fixed arm 21, and limits it from being separated from the fixed arm 21.

[0061] The hanging arm 22 is equipped with a lock catch 222, which can lock the hanging arm 22 when the hanging arm 22 is hung on the fixed arm 21, preventing it from accidentally separating from the fixed arm 21. This improves the safety of the television fixing assembly 2 and avoids the risk of the television falling due to the separation of the hanging arm 22.

[0062] As a preferred embodiment of the above embodiment, the cross beam 11 is further provided with a storage table 23, and the control box 231 is arranged on the storage table 23 and electrically connected with the lifting device for controlling the lifting device to lift.

[0063] The storage table 23 arranged on the cross beam 11 provides additional space, which can be used to place a remote controller, a sound equipment or other auxiliary tools. This enhances the functionality and practicability of the equipment, especially in a conference room or a home entertainment system, and the related equipment can be centrally managed to avoid the dispersion of articles. The control box 231 is electrically connected with the lifting device, and the brushless motor 121 and the transmission screw 122 can be operated through the control box 231 to realize the lifting adjustment of the television.
