Detailed Implementation

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figures 1 to 8 As shown in the figure, a lifting bracket in an embodiment of the present utility model includes: a bracket body 100, a support component 200, and a drive component 300.

[0032] Specifically, the bracket body 100 includes a fixed frame, a first lifting tube 110 and a second lifting tube 120 disposed opposite to each other on the fixed frame, and a lead screw is provided in both the first lifting tube 110 and the second lifting tube 120; a support assembly 200 is connected between the first lifting tube 110 and the second lifting tube 120, and the support assembly 200 is used to mount the display; a drive assembly 300 is connected to the bracket body 100, and the drive assembly 300 includes a transmission rod 310, a reversing structure 320 and a braking structure 330, both ends of the transmission rod 310 along its axial direction are connected to the reversing structure 320, the reversing structure 320 is connected to the lead screw, and the braking structure 330 is connected to the transmission rod 310.

[0033] The fixed frame forms the main structure of the bracket body 100, and the support component 200 provides support for the display, which can be a television, computer monitor, electronic display panel, or similar device. In one embodiment, the support component 200 includes two support crossbars arranged in parallel, with two hanging arms connecting them. The two hanging arms are arranged in parallel, and each hanging arm is connected to both support crossbars. Each hanging arm has multiple through holes for connecting to the display, thereby enabling the support component 200 to support and fix the display. In another embodiment, the number of support crossbars can be multiple, and these crossbars are not limited to being arranged in parallel; they can also be configured to be arranged crosswise. Correspondingly, the number of hanging arms can also be multiple, and they can also be arranged crosswise.

[0034] The first lifting tube 110 and the second lifting tube 120, which are arranged opposite to each other, are used to drive the support assembly 200 to rise and fall relative to the fixed frame, thereby raising or lowering the display fixed on the support assembly 200. When the transmission rod 310 on the drive assembly 300 rotates, it is converted into the rotation of the lead screw through the reversing structure 320, and the lead screw drives the first lifting tube 110 and the second lifting tube 120 to rise and fall.

[0035] The brake structure 330 is used to provide resistance to the transmission rod 310 when the first lifting tube 110 and the second lifting tube 120 are descending or stationary relative to the fixed frame, so as to prevent the display fixed on the support assembly 200 from automatically descending when the first lifting tube 110 and the second lifting tube 120 are stationary, or from descending too quickly.

[0036] In this solution, a braking structure is installed to prevent the lifting tube from descending too quickly during the descent process, thus ensuring the safety of the equipment. Furthermore, by placing the braking structure 330 on the transmission rod 310 instead of the lead screw, the braking structure 330 is prevented from occupying the lifting stroke of the lead screw, allowing the first lifting tube 110 and the second lifting tube 120 to have a larger lifting or lowering stroke, which better meets the user's needs.

[0037] The brake structure 330 includes a brake drum 331 fixed to the transmission rod 310 and a torsion spring 332 sleeved on the outside of the brake drum 331. Brake structures 330 are provided at both ends of the transmission rod 310, and the torsion springs 332 at both ends of the transmission rod 310 rotate in opposite directions. One end of the torsion spring 332 is connected to a fixed frame. The two ends of the transmission rod 310 are respectively connected to a reversing structure and a lead screw. Therefore, providing brake structures 330 at both ends of the transmission rod 310 not only ensures more stable synchronous operation of the first lifting tube 110 and the second lifting tube 120, but also improves the braking effect. Having the torsion springs 332 at both ends of the transmission rod 310 rotate in opposite directions not only ensures the above effects, but also further ensures that the brake structures on both sides of the transmission rod 310 are symmetrical and consistent, saving mold space and reducing the number of parts.

[0038] In one embodiment, the connection between the brake drum 331 and the transmission rod 310 can be achieved by configuring the transmission rod 310 as a rod with a polygonal cross-section and providing a hole structure in the brake drum 331 that matches the shape of the transmission rod 310. In another embodiment, the connection between the brake drum 331 and the transmission rod 310 can also be achieved by adhesive bonding, threaded connection, or integral molding.

[0039] One end of the torsion spring 332 is connected to the fixed frame, and the torsion spring 332 is sleeved on the outside of the brake drum 331. When the transmission rod 310 rotates, causing the lifting tube to descend, the torsion spring 332 tends to twist and tighten. At this time, the torsion spring 332 will provide greater friction to the brake drum 331, hindering the rotation of the brake drum 331. Since both ends of the transmission rod 310 are equipped with brake structures 330, when the lifting tube descends, the brake structures 330 at both ends of the transmission rod 310 can provide resistance to the rotation of the transmission rod 310, preventing the first lifting tube 110 and the second lifting tube 120 from descending rapidly and moving accidentally.

[0040] This solution also includes a brake cover 333, which is connected to a fixed frame. The brake cover 333 is provided with a slot 333a, and one end of the torsion spring 332 is pressed against the slot 333a.

[0041] In one embodiment, one end of the torsion spring 332 is bent to form a hook 332a, which abuts against the groove 333a to fix the torsion spring 332 on the brake cover 333.

[0042] Preferably, the brake drum 331 is made of plastic. When the first riser tube 110 and the second riser tube 120 descend, the torsion spring 332 is stretched and clamped to the brake drum 331 to provide resistance to the descent of the first riser tube 110 and the second riser tube 120.

[0043] The fixed frame includes a first fixed tube 130 and a second fixed tube 140 arranged opposite to each other. The first lifting tube 110 is movably engaged with the first fixed tube 130, and the second lifting tube 120 is movably engaged with the second fixed tube 140. A reversing structure 320 is provided in both the first fixed tube 130 and the second fixed tube 140. One end of the transmission rod 310 is connected to the reversing structure 320 in the first fixed tube 130, and the other end of the transmission rod 310 is connected to the reversing structure 320 in the second fixed tube 140.

[0044] The movable engagement between the first fixed tube 130 and the first lifting tube 110, and the movable engagement between the second fixed tube 140 and the second lifting tube 120, are both used to guide the moving first lifting tube 110 and the second lifting tube 120, enabling the display on the support assembly 200 to move smoothly. In one embodiment, the first fixed tube 130 and the second fixed tube 140 are defined as outer tubes, and the first lifting tube 110 and the second lifting tube 120 are defined as inner tubes, with the inner tube inserted inside the outer tube. In another embodiment, the first fixed tube 130 and the second fixed tube 140 are defined as inner tubes, and the first lifting tube 110 and the second lifting tube 120 are defined as outer tubes, again with the inner tube inserted inside the outer tube.

[0045] The fixed frame also includes: a main housing 150, which is sleeved on the outside of the transmission rod 310, one end of the main housing 150 is connected to the first fixed tube 130, the other end of the main housing 150 is connected to the second fixed tube 140, and the brake structure 330 is disposed inside the main housing 150.

[0046] The main housing 150 is configured as a fixed frame connection structure for connecting the first fixed tube 130 and the second fixed tube 140. The main housing 150 is sleeved on the outside of the transmission rod 310, and the brake structure 330 is disposed inside the main housing 150 to prevent the transmission rod 310 and the brake structure 330 from being interfered with by external factors.

[0047] In one embodiment, the drive assembly 300 further includes: a first outer shell 340 and a second outer shell 350 connected within the main housing 150, forming an active space between the first outer shell 340 and the second outer shell 350; a cover plate 152 snapped onto the main housing 150, the cover plate 152 being disposed opposite to the first outer shell 340 and the second outer shell 350; a drive bevel gear 360, which is rotatably disposed within the active space and fixedly sleeved on the outside of the drive rod 310; a reversing bevel gear 370, which is rotatably disposed between the first outer shell 340 and the second outer shell 350 and meshes with the drive bevel gear 360; and a drive handle 380, one end of which passes through the side wall of the main housing 150 and is connected to the reversing bevel gear 370.

[0048] When the drive handle 380 rotates, it drives the reversing bevel gear 370 to rotate. Since the reversing bevel gear 370 meshes with the transmission bevel gear 360, and the transmission bevel gear 360 is fixedly connected with the transmission rod 310, the rotation of the drive handle 380 can be converted into the rotation of the transmission rod 310, thereby driving the movement of the first lifting tube 110 and the second lifting tube 120. The cover plate 152 is used to facilitate the disassembly and assembly of the first outer shell 340 and the second outer shell 350 in the main shell 150, and improves the aesthetics of the main shell 150 after the first outer shell 340 and the second outer shell 350 are fixed in the main shell 150.

[0049] The fixed frame also includes: a fixed plate 334, which is fixedly connected to both ends of the main housing 150; a brake cover 333 located inside the main housing 150 and connected to the fixed plate 334, forming a fixed space between the brake cover 333 and the fixed plate 334; and a torsion spring 332 and a brake drum 331 both located within the fixed space.

[0050] The fixing plate 334 is configured as a fixing reference for the brake cover 333 within the main housing 150, and both the torsion spring 332 and the brake drum 331 are fixed in the fixed space formed between the brake cover 333 and the fixing plate 334, so that the movement of the torsion spring 332 and the brake drum 331 is not disturbed by the external environment.

[0051] Both ends of the main housing 150 along the axis of the transmission rod 310 are provided with baffles 151, and the fixing plate 334 is connected to the baffles 151. The baffles 151 are connected to the first fixing tube 130 or the second fixing tube 140.

[0052] The baffle 151 is used to fix the fixing plate 334 inside the main housing 150, ensuring the accurate installation of the fixing plate 334 inside the main housing 150. It is also configured as a sealing component at both ends of the main housing 150, so that the brake cover 333, torsion spring 332 and transmission rod 310 inside the main housing 150 cannot be observed from the outside, thereby improving the aesthetics of the lifting bracket.

If the specific posture changes, the directional indicator will also change accordingly.
