[0024] See also Figures 1 to 3 , Figure 1 1 is a schematic diagram of the three-dimensional structure of a lifting bracket 100 according to an embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the exploded structure of the lifting bracket 100 after the connecting seat 12 and the base are hidden; Figure 3 yes Figure 2A schematic diagram of the three-dimensional structure of the lifting bracket 100 with the rear cover 112 hidden. An embodiment of the present invention provides a lifting bracket 100 comprising a mounting base 10, a lifting block 20, and a cable protection cover 30. The lifting block 20 is movably coupled to the mounting base 10. The lifting block 20 has a front side 210 and a rear side 220. The lifting block 20 defines a cable passage 201 extending through the front and rear sides 210 and 220. The front side 210 is used to mount a display, and the cable passage 201 is used to pass cables connected to the display. The cable protection cover 30 is mounted on the mounting base 10 and faces the rear side 220. The cable protection cover 30 defines a cable passage hole 301 for passing cables extending from the cable passage hole 201, thereby constraining the cables to the side of the cable protection cover 30 facing away from the lifting block 20. When the lifting block 20 moves relative to the mounting base 10, it drives the cables through the cable passage hole 301.
[0025] Specifically, the mounting base 10 includes a mounting body 11, a connecting base 12, and a supporting base 13, wherein the supporting base 13 is used to be set on a desktop or other supporting surface, one end of the connecting base 12 is connected to the supporting base 13, and the other end is connected to the mounting body 11 so as to be relatively rotatable. The mounting body 11 can rotate in the vertical plane relative to the connecting base 12 to adjust the pitch angle of the display. Components such as the lifting block 20 and the wire protection cover 30 are all installed on the mounting body 11, and the lifting block 20 can move relative to the mounting base 10 in the vertical direction. In this embodiment, please refer to Figures 4 to 6 Two parallel slide rails 14 are provided in the mounting body 11, and the lifting block 20 is provided with a ball groove 202 extending in the vertical direction. A plurality of balls (not shown) arranged in the vertical direction are provided in the slide rail 14. The balls cooperate with the ball groove 202 to provide vertical guidance for the lifting block 20 and reduce the friction force on the lifting block 20 during the lifting process.
[0026] Specifically, the threading portion 201 can be configured as a through hole, a through slot, or other structure. The present invention does not limit the specific structure of the threading portion 201. In this embodiment, the threading portion 201 is a through hole and is arranged opposite the wire hole 301 to facilitate the sequential passage of the cable through the threading portion 201 and the wire hole 301, thereby reducing the risk of cable snagging and twisting.
[0027] It should be noted that the front side 210 and the rear side 220 of the lifting block 20 are opposite to each other. In this embodiment, the side of the lifting block 20 where the monitor is mounted is defined as the front side 210, and the other side is defined as the rear side 220. The front side 210 of the lifting block 20 is installed with a mounting block 80, which is used to mount the monitor. The mounting block 80 is provided with a wire entry hole 801 opposite to the wire threading portion 201. The cable connecting the monitor passes through the mounting block 80, then passes through the wire entry hole 801 and extends into the wire threading portion 201. For ease of understanding, Figure 3Component A in the figure is a cable, which shows the routing plan of cable A.
[0028] Specifically, the mounting body 11 includes a front shell 111 and a rear cover 112, which together form a mounting cavity. The lifting block 20 and the wire protection cover 30 are both disposed within the mounting cavity. The wire protection cover 30 and the two slide rails 14 are both mounted and fixed to the front shell 111. The front shell 111 defines a movable hole 101. The end of the mounting block 80, away from the display, extends into the mounting cavity through the movable hole 101 and is fixedly connected to the lifting block 20, thereby achieving synchronous lifting and lowering of the mounting block 80 and the lifting block 20. The movable hole 101 is a long strip extending in the vertical direction, providing space for the lifting and lowering of the mounting block 80.
[0029] By setting a wire protection cover 30, the wire protection cover 30 is opposite to the rear side 220 of the lifting block 20 and is provided with a wire passing hole 301. After the cable passes through the threading part 201 of the lifting block 20, it can pass through the wire passing hole 301 and be constrained to the side of the wire protection cover 30 facing away from the lifting block 20. The wire protection cover 30 can isolate the cable and the lifting block 20. During the lifting process of the lifting block 20, the cable can move in the wire passing hole 301, and the cable is not easily hung or twisted by the lifting block 20, thereby improving the service life of the cable and making the lifting action smooth.
[0030] In one embodiment of this embodiment, please refer to Figure 2 and Figure 4 , Figure 4 yes Figure 3 A schematic diagram of the three-dimensional structure of the lifting bracket 100, with the front housing 111 concealed. The cable hole 301 is a strip-shaped hole extending in the same direction as the lifting block 20 moves relative to the mounting base 10. This arrangement allows cables to move within the cable hole 301 along its extending direction during the lifting of the lifting block 20, ensuring smooth lifting motion.
[0031] In this embodiment, the inner walls of the wire hole 301 and the wire threading portion 201 are both relatively convex arc surfaces, so as to reduce the risk of the cable being scratched during the lifting process.
[0032] In one embodiment of this embodiment, please refer to Figure 2 and Figure 4 The cable cover 30 is provided with a cable management structure 40 for restraining the cables. This arrangement allows the cables to be positioned on the cable cover 30, allowing them to be routed along a pre-set path. The cables will not wander during the lifting process, reducing the risk of getting hung or twisted.
[0033] Specifically, the cable management structure 40 can be a buckle, a stopper with a cable routing hole, or other structure. In this embodiment, to reduce costs, the cable management structure 40 is a portion of the cable protection cover 30. It is formed by stamping and bending and has a certain degree of elasticity to provide stable cable restraint. In other embodiments, the cable management structure 40 can be another component secured to the cable protection cover 30 by welding, threading, or other methods.
[0034] In one embodiment of this embodiment, please refer to Figure 3 、 Figure 4 and Figure 7 , Figure 7 yes Figure 6 A schematic diagram of the three-dimensional structure of the cable protection cover 30 in the lifting bracket 100. Multiple cable management structures 40 are arranged around the cable hole 301. This arrangement facilitates routing cables around the cable hole 301. The cables have a certain curvature, allowing them to bend more smoothly during the lifting process, thereby reducing the impact on the smoothness of the lifting movement.
[0035] In this embodiment, there are four cable management structures 40, which are arranged around the bottom of the cable hole 301. The mounting base 10 is provided with a cable outlet hole 102. Two of the cable management structures 40 are arranged on the same side of the cable hole 301 in the width direction, and the other two are arranged on the bottom side of the cable hole 301 in the length direction and are arranged opposite the cable outlet hole 102. This ensures that the cables pass through the four cable management structures 40 in sequence and then exit the cable outlet hole 102.
[0036] In one embodiment of this embodiment, please refer to Figure 3 、 Figure 4 and Figure 7 The cable management structure 40 includes an elastic portion 41 and a restraining portion 42. One end of the elastic portion 41 is connected to the cable protection cover 30, and the other end is connected to the restraining portion 42. The restraining portion 42 is suspended above the cable protection cover 30 and is used to cooperate with the cable protection cover 30 to clamp the cable. This arrangement allows the elastic portion 41 to provide the restraining portion 42 with a clamping force that can clamp the cable, ensuring that the cable management structure 40 can stably restrain the cable. In addition, the elastic portion 41 can change the distance between the restraining portion 42 and the cable protection cover 30, allowing the cable management structure 40 to clamp cables of different core diameters, improving its applicability.
[0037] Specifically, the elastic portion 41 and the restraining portion 42 are both sheet-shaped to provide good deformation performance and better clamping effect.
[0038] In one embodiment of this embodiment, please refer to Figures 5 to 7 , Figure 5 yes Figure 4 A schematic diagram of the exploded structure of the lifting bracket 100; Figure 6 is Figure 4 The three-dimensional structural schematic diagram of the lifting bracket 100 after hiding the elastic member 50 and the slide rail 14; Figure 8 is Figure 7 The enlarged structural schematic diagram of region I of. The lifting bracket 100 includes an elastic member 50, the elastic member 50 is installed on the mounting base 10 and is connected to the lifting block 20. The wire protection cover plate 30 includes side plates 31, the side plates 31 face the elastic member 50 and are used to isolate the cable and the elastic member 50. By arranging the side plates 31 to isolate the cable and the elastic member 50, it is possible to avoid interference between the cable and the elastic member 50 during the lifting process, reduce the occurrence of cable twisting and hanging, and reduce the impact on the lifting movement of the lifting block 20.
[0039] In this embodiment, the elastic member 50 is a constant force tension spring, and the constant force tension spring provides a constant upward pulling force for the lifting block 20 to offset at least part of the gravity of the display, so that the user can adjust the height of the display with a smaller force and improve the use experience.
[0040] In this embodiment, the wire protection cover plate 30 includes a bottom plate 32, a wire passing hole 301 is opened on the bottom plate 32, and a wire management structure 40 is arranged on the bottom plate 32. The number of the elastic members 50 and the side plates 31 is two each. The two side plates 31 are respectively connected to both sides of the bottom plate 32, and the wire protection cover plate 30 is integrally in an inverted U shape. The two elastic members 50 are both installed and fixed on the mounting base 10, the two elastic members 50 are respectively arranged opposite to the corresponding side plates 31, and the two elastic members 50 are both connected to the lifting block 20 to provide a more stable pulling force for the lifting block 20.
[0041] In this embodiment, the side plate 31 is arranged opposite to the slide rail 14 and is used to isolate the cable and the slide rail 14. With such an arrangement, it is possible to prevent the cable from interfering with the slide rail 14 during the lifting process.
[0042] In an embodiment of this implementation manner, please refer to Figure 4 、 Figure 5 and Figure 10 , Figure 10 is Figure 7 The three-dimensional structural schematic diagram of the lifting block 20 and the fixing plate 60 in the lifting bracket 100 of. The lifting bracket 100 includes a fixing plate 60, the fixing plate 60 is connected to the lifting block 20, one side of the fixing plate 60 is connected to the elastic member 50, and the other side is opposite to the side plate 31. With such an arrangement, the side plate 31 can isolate the cable and the fixing plate 60, and it is possible to avoid interference between the cable and the fixing plate 60 during the lifting process, make the lifting movement smooth, and reduce the occurrence of cable twisting and hanging.
[0043] In this embodiment, the number of the fixing plates 60 is two, and the two fixing plates 60 are fixedly installed on the rear side 220 of the lifting block 20 and respectively isolate the cable and the corresponding elastic member 50.
[0044] In one embodiment of this embodiment, please refer to Figure 4 、 Figure 7 and Figure 8 The side panel 31 is formed with a flange structure 311, and at least a portion of the flange structure 311 extends to the side of the fixed plate 60 facing away from the lifting block 20. In this manner, the flange structure 311 and the side panel 31 can cooperate to fully isolate the cables from the fixed plate 60, further reducing the risk of wire tangling and hanging.
[0045] In this embodiment, both side panels 31 are provided with flange structures 311 to isolate the cables from the corresponding fixing plates 60 .
[0046] In this embodiment, the flange structure 311 and the side plate 31 are transitionally connected via the rounded corner structure 312 . The curved surface of the rounded corner structure 312 can reduce the risk of the cable being scratched.
[0047] In one embodiment of this embodiment, please refer to Figure 6 and Figure 9 , Figure 9 yes Figure 7 Schematic diagram of the three-dimensional structure of the cable management block 70 in the lifting bracket 100; the lifting bracket 100 includes a cable management block 70, which is mounted on the lifting block 20 and passes through the cable hole 301. The cable management block 70 has a wire winding groove 701 for accommodating some of the cables that pass through the cable hole 301. By arranging the cable management block 70 on the lifting block 20, some of the cables that pass through the cable hole 301 can be accommodated in the wire winding groove 701 on the cable management block 70, ensuring that the cables can be routed along the predetermined path without contacting the mounting base 10, and the lifting action is smooth. At the same time, the cable management block 70 cooperates with the cable protection cover 30 to stably restrain the cables on the side of the cable protection cover 30 facing away from the lifting block 20. It can be understood that during the lifting process, the cable management block 70 and the lifting block 20 move synchronously, so that some of the cables that pass through the cable hole 301 can be restrained by the cable management block 70 immediately, reducing the risk of the cables becoming unconstrained.
[0048] In this embodiment, the cable management block 70 is fixed to the rear side 220 of the lifting block 20 by fasteners.
[0049] In one embodiment of this embodiment, please refer to Figure 9The cable management block 70 is provided with a limiting buckle 71, which has a connected wire channel 7101 and a wire release port 7102. When the limiting buckle 71 is in the open state, the wire release port 7102 can be used to place the cable passing through the wire hole 301 into the wire channel 7101. When the limiting buckle 71 is in the closed state, the wire release port 7102 is closed to restrict the cable from leaving the wire channel 7101. Through the above arrangement, when routing the wires, the limiting buckle 71 can be opened first to open the wire release port 7102, and then the cable can be placed into the wire channel 7101 from the wire release port 7102. After the cable is placed into the wire channel 7101, the limiting buckle 71 can be closed to restrict the cable from being confined within the wire channel 7101, thereby realizing the restraint function of the cable management block 70.
[0050] In this embodiment, the winding groove 701 is opposite to the outlet of the wire passage 7101. After the cable passes through the wire hole 301, it passes through the wire passage 7101 and the winding groove 701 in sequence, thereby fully restraining the cable.
[0051] In this embodiment, the position-limiting buckle 71 includes a fixed portion 711 and an elastic snap-fit portion 712, which together form a cable passage 7101. When the position-limiting buckle 71 is in the open position, the fixed portion 711 and the elastic snap-fit portion 712 separate, forming a cable release opening 7102 therebetween for inserting cables into the cable passage 7101. When the elastic snap-fit portion 712 is subjected to an external force and snaps into engagement with the fixed portion 711, the cable release opening 7102 is closed, and the position-limiting buckle 71 is in the closed position, preventing cables from exiting the cable passage 7101 through the cable release opening 7102.
[0052] In this embodiment, the cable management block 70 defines a clearance groove 702. The clearance groove 702 faces the cable management structure 40 in the direction of movement of the lifting block 20 relative to the mounting base 10. This arrangement allows the clearance groove 702 to clear the cable management structure 40 during the lifting and lowering of the lifting block 20, preventing interference between the cable management block 70 and the cable management structure 40.

Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
