An embodiment of the present invention provides a display lifting bracket 100, which includes a support seat 10, a guide structure 20 and a mounting assembly 30. The support seat 10 is provided with a accommodating cavity 101, and the guide structure 20 is installed in the accommodating cavity 101. The mounting assembly 30 includes a mounting seat 31, a slider 32 and a supporting structure 33. The mounting seat 31 is connected to the slider 32 and is used to install the display. The slider 32 extends into the accommodating cavity 101 and is connected to the guide structure 20 so that it can move relatively. The slider 32 can drive the mounting seat 31 and the display to rise and fall relative to the support seat 10. The supporting structure 33 is arranged on the slider 32 and abuts against the side wall 1011 of the accommodating cavity 101 close to the mounting seat 31.

[0025] Specifically, the support base 10 is used to be set on a support surface such as a desktop or a wall. In this embodiment, the support base 10 includes a shell 11 and a base 12, and the base 12 is used to be placed on the desktop to support the display. The shell 11 is connected to the surface of the base 12 facing away from the desktop, and is provided with a receiving cavity 101. For the convenience of description, the up and down direction of the display lifting bracket 100 when observing the display is defined as the height direction, the left and right direction of the display lifting bracket 100 is defined as the width direction, and the front and rear direction of the display lifting bracket 100 is defined as the thickness direction.

[0026] Specifically, the slider 32 can be connected to the guide structure 20 by sliding fit of the groove and the protrusion to achieve relative movement, and the slider 32 can also be connected to the guide structure 20 by rolling fit of the ball and the guide groove to achieve relative movement. The guide structure 20 can be an integrated structure with the support seat 10, for example, the guide structure 20 is configured as a slide groove opened in the accommodating cavity 101 of the support seat 10. The guide structure 20 can also be a split structure with the support seat 10, for example, the guide structure 20 is a guide rail installed in the accommodating cavity 101 of the support seat 10. In this embodiment, the mounting seat 31 is located outside the accommodating cavity 101, a part of the slider 32 is connected to the mounting seat 31, and the other part of the slider 32 extends into the accommodating cavity 101 and is connected to the guide structure 20 in a relatively movable manner. The direction of relative movement of the slider 32 and the guide structure 20 is a vertical direction, so that the slider 32 moves relative to the guide structure 20 to drive the mounting seat 31 and the display to rise and fall relative to the support seat 10.

[0027] By arranging a support structure 33 on the slider 32, the support structure 33 and the side wall 1011 of the accommodating cavity 101 close to the mounting seat 31 are abutted, and the support structure 33 can cooperate with the support seat 10 to provide auxiliary support to the slider 32, thereby reducing the force on the guide structure 20, reducing the risk of the guide structure 20 tilting and deforming forward, and improving the supporting capacity, so as to support a heavy display. At the same time, since the force on the guide structure 20 is reduced, the strength requirement of the guide structure 20 is reduced, and the volume of the guide structure 20 is reduced, so as to meet the requirements of miniaturization design.

[0028] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , Figure 4 yes Figure 1 The three-dimensional structural diagram of the slider 32 and the support structure 33 in the display lifting bracket 100 in the exploded state. The support structure 33 includes a rotating wheel 331 and a rotating shaft 332. The rotating wheel 331 is rotatably connected to the slider 32 through the rotating shaft 332, and the outer peripheral surface of the rotating wheel 331 abuts against the side wall 1011. By providing the rotating shaft 332 and the rotating wheel 331, the rotating wheel 331 can rotate relative to the slider 32, and the outer peripheral surface of the rotating wheel 331 abuts against the side wall 1011, which can ensure that the rotating wheel 331 can be tightly pressed against the side wall 1011 to support the slider 32, while reducing the friction force on the slider 32, so that the slider 32 can be lifted and lowered more smoothly.

[0029] In this embodiment, the rotating shaft 332 is rotationally matched with the rotating wheel 331, and the rotating shaft 332 is fixedly connected with the slider 32 to realize the relative rotation of the rotating wheel 331 and the slider 32. In other embodiments, the rotating shaft 332 can also be fixedly connected with the rotating wheel 331, and the rotating shaft 332 is rotationally matched with the slider 32 to realize the relative rotation of the rotating wheel 331 and the slider 32. In other embodiments, the rotating wheel 331 can be constructed as a bearing, the rotating shaft 332 is fixedly connected with the inner ring of the bearing and the slider 32, and the outer peripheral surface of the outer ring of the rotating shaft 332 abuts against the side wall 1011 to further reduce the friction force on the slider 32.

[0030] In one embodiment of this implementation, please refer to Figure 3 and Figure 4, there are two rotating wheels 331, the slider 32 is provided with an axial hole 321, the rotating shaft 332 is passed through the axial hole 321, and the two ends of the rotating shaft 332 extend out of the axial hole 321 and are respectively connected to the two rotating wheels 331. Specifically, the two rotating wheels 331 are provided with a connecting hole 3311, and the two ends of the rotating shaft 332 extend into the connecting hole 3311 and rotate with the connecting hole 3311, and the middle part of the rotating shaft 332 is interference fit with the axial hole 321. By providing two rotating wheels 331, the two rotating wheels 331 are respectively connected to the two ends of the rotating shaft 332, and the support structure 33 can fully contact with the side wall 1011 to better assist in supporting the slider 32, and further reduce the risk of the guide structure 20 being deformed forward. At the same time, the strength requirement of the guide structure 20 is further reduced, which is conducive to reducing the volume of the guide structure 20, and the display lifting bracket 100 meets the miniaturized design requirements.

[0031] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 The rotating shaft 332 and the slider 32 are an integrated structure, the rotating shaft 332 protrudes from the surface of the slider 32, and rotates with the rotating wheel 331. Specifically, the rotating shaft 332 is configured as a relatively protruding cylinder on the slider 32, the cylinder extends into the connecting hole 3311 of the rotating wheel 331, and rotates with the connecting hole 3311. Through the above arrangement, the relative position of the slider 32 and the rotating wheel 331 can be ensured to be accurate, and the outer peripheral surface of the rotating wheel 331 can be better fitted with the side wall 1011.

[0032] In one embodiment of this implementation, please refer to Figure 3 and Figure 4 , there are multiple support structures 33, and the multiple support structures 33 are arranged along the direction of relative movement between the slider 32 and the support seat 10. Specifically, the multiple support structures 33 are arranged along the vertical direction, and there is a spacing distance between two adjacent support structures 33. By providing multiple support structures 33, the multiple support structures 33 can abut against the side wall 1011 at the same time, so that the slider 32 obtains better support, and the risk of the guide structure 20 being deformed forward is further reduced. At the same time, the strength requirement of the guide structure 20 is further reduced, which is conducive to reducing the volume of the guide structure 20, and the display lifting bracket 100 meets the miniaturized design requirements.

[0033] In one embodiment of this implementation, please refer to Figure 2 and Figure 3A guide groove 102 is provided on one side of the support seat 10 facing the mounting seat 31. The guide groove 102 is connected to the accommodating cavity 101, and a portion of the slider 32 is slidably matched with the guide groove 102. On the one hand, the slider 32 can extend into the accommodating cavity 101 through the guide groove 102, so that the slider 32 is connected to the guide structure 20. On the other hand, the guide groove 102 can provide guidance for the slider 32, improve the accuracy of the lifting action, and the guide groove 102 can limit the slider 32 from swinging along the horizontal plane, thereby improving the smoothness of the lifting action.

[0034] Specifically, the guide groove 102 is provided on the side wall 1011 abutted by the support structure 33 and extends in the vertical direction. When the slider 32 drives the mounting seat 31 to rise and fall relative to the support seat 10, the slider 32 can move along the guide groove 102. In this embodiment, the guide groove 102 separates the side wall 1011 abutted by the support structure 33 into two parts in the width direction, and the two wheels 331 in the support structure 33 abut against the two parts of the side wall 1011 respectively, so that the force on the side wall 1011 is more uniform, reducing the risk of deformation of the support seat 10.

[0035] In one embodiment of this implementation, please refer to Figure 2 and Figure 5 , Figure 5 yes Figure 1 The three-dimensional structural diagram of the slider 32, the support structure 33 and the guide structure 20 in the display lifting bracket 100 in the exploded state. The guide structure 20 includes a fixed frame 21, a retaining frame 22 and a ball array (not shown in the figure), the ball array is embedded in the retaining frame 22, the fixed frame 21 is provided with a first guide groove 211, and the slider 32 is provided with a second guide groove 322 opposite to the first guide groove 211. One side of the ball array is in contact with the inner wall of the first guide groove 211, and the other side of the ball array is in contact with the inner wall of the second guide groove 322. In this way, the slider 32 can be lifted and lowered relative to the support seat 10, and the retaining frame 22 and the fixed frame 21 can be used to support the slider 32 to a certain extent.

[0036] Specifically, the retainer 22 is provided with a plurality of ball holes 221 arranged in sequence and spaced apart in the vertical direction, and the ball array includes a plurality of balls, and the plurality of balls are respectively embedded in the corresponding ball holes 221. The inner walls of the first guide groove 211 and the second guide groove 322 are both arc surfaces, so as to fit with the two sides of the plurality of balls respectively, and the first guide groove 211 and the second guide groove 322 with the arc surface structure can limit the balls from being disengaged in the horizontal direction, and can provide certain support to the slider 32.

[0037] It is understandable that, due to the existence of the support structure 33, the structural strength requirements of the fixing frame 21 and the retaining frame 22 are reduced, and the fixing frame 21 and the retaining frame 22 of smaller size can be used to realize the lifting and lowering of the slider 32, thereby reducing the overall volume of the display lifting bracket 100. The number of balls in the ball array can also be appropriately reduced, thereby reducing the cost and simplifying the structure.

[0038] In this embodiment, the fixing frame 21 is fixed in the accommodating cavity 101, and the retaining frame 22 is sleeved on the end of the slider 32 away from the mounting seat 31. During the lifting process of the slider 32, the fixing frame 21 and the retaining frame 22 will move relative to each other, and the slider 32 and the retaining frame 22 will move relative to each other.

[0039] In one embodiment of this implementation, please refer to Figure 2 and Figure 5 , the number of the ball array, the first guide groove 211 and the second guide groove 322 are all two, and the two second guide grooves 322 are respectively opened on the opposite sides of the slider 32, and the two sides of each ball array are respectively matched with the corresponding first guide groove 211 and second guide groove 322. Specifically, the two second guide grooves 322 are respectively opened on the opposite sides of the slider 32 in the width direction, so that the space occupied by the guide structure 20 in the thickness direction can be reduced, which is conducive to reducing the thickness of the display lifting bracket 100.

[0040] In one embodiment of this implementation, please refer to Figure 2 and Figure 6 , Figure 6 yes Figure 1 Schematic diagram of the three-dimensional structure of the display lifting bracket 100 after hiding the mounting seat 31 and part of the supporting seat 10.

One end of the rope 40 is connected to the elastic structure 60, and the other end of the rope 40 passes around the fixed pulley 50 and is connected to the slider 32. Specifically, the fixed pulley 50 and the elastic structure 60 are respectively located on both sides of the slider 32 in the height direction. With such a configuration, the space of the accommodating cavity 101 in the height direction can be fully utilized, which is conducive to reducing the thickness of the display lifting bracket 100.

[0041] In one embodiment of this implementation, please refer to Figure 2 and Figure 6 The elastic structure 60 includes a plurality of elastic members 61, which are arranged along the direction of relative movement between the slider 32 and the support seat 10. Specifically, the elastic members 61 are configured as constant force springs, and there are two of them, and both constant force springs are connected to one end of the rope 40 away from the slider 32. In this way, the space of the accommodating cavity 101 in the height direction can be further fully utilized.

In this way, the space of the receiving cavity 101 in the height direction can be fully utilized, and at the same time, the loads received by the fixed pulley 50 and the elastic structure 60 can be borne by the support plate 13.

[0043] Specifically, the fixing frame 21 is fixed to the front side of the support plate 13, and the loads generated by the fixing frame 21, the fixed pulley 50, and the elastic structure 60 are all borne by the support plate 13, thereby reducing the stress on the housing 11 of the support seat 10. The support seat 10 is made of a relatively low-cost plastic material, and the support plate 13 is made of a relatively high-strength alloy material.
