[0030] The embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0031] In the description of the present application, it should be understood that, if the orientation description, such as up, down, left, right, front, back and the like, is described, the orientation or position relationship shown in the drawings is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0032] In the description of the present application, if the first, second, etc. are described, they are only used to distinguish technical features for the purpose, and cannot be understood as indicating or implying the relative importance of the technical features indicated or implied, or implicitly indicating the number of technical features indicated or implicitly indicating the sequence of technical features indicated.

[0033] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0034] The following will be described with reference to Figures 1 to 5 The first aspect of the present application is described in detail.

[0035] Reference Figures 1 to 2The utility model discloses a lifting support, which comprises a frame body 100, a lifting seat 200 and a constant force spring 300, the frame body 100 is provided with a sliding groove 110 extending along a first direction; the lifting seat 200 is slidably arranged in the sliding groove 110 along the first direction; the constant force spring 300 is arranged in the sliding groove 110, and the constant force spring 300 comprises a winding drum part 310 and a connecting part 320 connected with each other, the winding drum part 310 is rotatably arranged on the frame body 100, and the rotation axis of the winding drum part 310 is parallel to the thickness direction of the frame body 100; the connecting part 320 is connected with the lifting seat 200, and the constant force spring 300 can provide the lifting seat 200 with an elastic force for keeping at a preset height.

[0036] It should be noted that when the weight of the display is relatively light, the axial dimension of the constant force spring 300 required in the lifting support is smaller than the radial dimension of the constant force spring 300, so as to ensure the pulling force of the constant force spring 300 on the display, thereby achieving the floating fixation of the display. The winding drum part 310 and the connecting part 320 are integrated, the winding drum part 310 is in a winding state, when the connecting part 320 is subjected to an external force, the winding drum part 310 is unwound, the part connected between the winding drum part 310 and the connecting part 320 is straightened and forms part of the connecting part 320; when the winding drum part 310 is wound, the part connected between the connecting part 320 and the winding drum part 310 is wound to the outside of the winding drum part 310 and forms part of the winding drum part 310.

[0037] In the lifting support of the present application, the lifting seat 200 is connected with the connecting part 320 of the constant force spring 300, and the winding drum part 310 is rotatably arranged in the sliding groove 110, when the lifting seat 200 slides downward along the first direction under the action of an external force, the lifting seat 200 drives the connecting part 320 of the constant force spring 300 to slide downward along the first direction, the winding drum part 310 rotates under the action of the connecting part 320, the winding drum part 310 is unwound, and the connecting part 320 is elongated, when the lifting seat 200 reaches the preset height, the force applied on the lifting seat 200 is removed, at this time, the elastic force of the constant force spring 300 applied on the lifting seat 200 is equal to the gravity of the lifting seat 200 itself, so that the lifting seat 200 is kept at the preset height; when the lifting seat 200 slides upward along the first direction under the action of an external force, since the applied force and the direction provided by the constant force spring 300 are the same, the winding drum part 310 of the constant force spring 300 rotates to wind the connecting part 320, thereby driving the connecting part 320 to move upward along the first direction, when the lifting seat 200 reaches the preset height, the force applied on the lifting seat 200 is removed, at this time, the elastic force of the constant force spring 300 applied on the lifting seat 200 is equal to the gravity of the lifting seat 200 itself, so that the lifting seat 200 is kept at the preset height.

[0038] It can be understood that since the axial dimension of the reel portion 310 is smaller than the radial dimension of the reel portion 310, by rotatably setting the reel portion 310 in the slide groove 110, and the rotation axis of the reel portion 310 is parallel to the thickness direction of the frame 100, the dimension of the reel portion 310 in the thickness direction of the frame 100 is smaller, which can reduce the space occupied by the reel portion 310 in the thickness direction of the frame 100, thereby making the dimension of the lifting bracket in the thickness direction smaller.

[0039] It can be understood that since the drum portion 310 is rotatably arranged on the bottom of the slide groove 110, when the lifting seat 200 moves along the first direction, the drum portion 310 can only rotate on the frame 100, and the connecting portion 320 moves along the first direction with the lifting seat 200. Since the axial direction of the drum portion 310 of the constant force spring 300 is parallel to the thickness direction of the frame 100, it should be noted that the width direction of the lifting bracket in the horizontal direction is defined as the second direction, the second direction is perpendicular to the first direction, and the thickness direction of the connecting portion 320 corresponds to the second direction. Therefore, the size of the slide groove 110 in the second direction can be set smaller to reduce the size of the frame 100 in the second direction. Therefore, the space required for the connecting portion 320 of the constant force spring 300 to move is smaller, and therefore the space required for the constant force spring 300 as a whole in the second direction is relatively small.

[0040] Specifically, the first direction is a vertical direction or a direction inclined relative to the vertical direction. The thickness direction of the frame 100 is perpendicular to the first direction and perpendicular to the bottom of the sliding groove 110 .

[0041] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the lifting bracket includes a plurality of fixed force springs 300, including a first fixed force spring 400 and a second fixed force spring 500. The orthographic projections of the first fixed force spring 400 and the second fixed force spring 500 on a plane perpendicular to the first direction at least partially overlap. It is understood that because the orthographic projections of the first fixed force spring 400 and the second fixed force spring 500 on a plane perpendicular to the first direction at least partially overlap, the space occupied by the first fixed force spring 400 and the second fixed force spring 500 in the horizontal direction is reduced, thereby making the lifting bracket more compact in the horizontal direction.

[0042] refer to Figure 1 and Figure 2In some embodiments, the connecting portion 320 of the first constant force spring 400 and the reel portion 310 of the second constant force spring 500 are located on the same horizontal plane. It is understood that because the connecting portion 320 of the first constant force spring 400 and the reel portion 310 of the second constant force spring 500 are located on the same horizontal plane, the reel portion 310 of the first constant force spring 400 and the reel portion 310 of the second constant force spring 500 are relatively close in the vertical direction. As a result, the first constant force spring 400 and the second constant force spring 500 occupy less space in the vertical direction, making the lifting bracket more compact in the vertical direction.

[0043] refer to Figure 2 In one embodiment, the two reel portions 310 of the first constant force spring 400 and the second constant force spring 500 are both located between the two connecting portions 320. It is understood that because the orthographic projections of the two reel portions 310 on a plane perpendicular to the first direction at least partially overlap, when the two reel portions 310 of the first constant force spring 400 and the second constant force spring 500 are both located between the two connecting portions 320, the lift base 200 is respectively connected to the two connecting portions 320. The symmetrical arrangement of the two connecting portions 320 makes the structure of the lift base 200 connected thereto also symmetrical, thereby making the structure of the lift base 200 more symmetrical. Since the structures of the lift base 200 connected to the two connecting portions 320 are symmetrical, the elastic forces applied to the lift base 200 by the two constant force springs 300 are more uniform.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, at least one limiting protrusion 120 is provided within the chute 110. The limiting protrusion 120 divides the chute 110 into a plurality of horizontally distributed sub-chute 111. The sub-chute 111 is provided in a one-to-one correspondence with the fixed force spring 300, and the connecting portion 320 is capable of moving along the first direction within the corresponding sub-chute 111. It can be understood that by providing the limiting protrusion 120 within the chute 110, the chute 110 is divided into a plurality of sub-chute 111 with smaller horizontal dimensions. The sub-chute 111 guides the corresponding connecting portion 320 of the fixed force spring 300 to perform lifting and lowering motion, thereby reducing the horizontal movable space of the portion of the lift base 200 connected to the connecting portion 320, thereby increasing the stability of the lift base 200 sliding along the first direction.

[0045] Specifically, a limiting protrusion 120 is provided in the chute 110 , and the limiting protrusion 120 divides the chute 110 into two sub-chute chutes 111 .

[0046] refer to Figure 1 、 Figure 3 and Figure 4In some embodiments of the utility model, the connecting part 320 is bent to form a slot 320a with an opening upward, the lifting seat 200 is arranged in the slot 320a and abuts against the bottom of the slot 320a. It can be understood that when the lifting seat 200 slides downward along the first direction under the action of external force, the lifting seat 200 abuts against the bottom of the slot 320a, the lifting seat 200 provides a downward sliding force to the connecting part 320, so that the connecting part 320 moves downward along the first direction and the winding drum part 310 unwinds.

[0047] It can be understood that the two side walls of the slot 320a abut against the lifting seat 200, and when the lifting seat 200 slides upward along the first direction under the action of external force, the two side walls of the slot 320a abut against the lifting seat 200, which increases the friction between the lifting seat 200 and the connecting part 320, so that the lifting seat 200 is not easy to separate from the slot 320a, and a fixing structure for limiting the lifting seat 200 from separating from the slot 320a is not needed between the connecting part 320 and the lifting seat 200.

[0048] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the lifting seat 200 comprises an abutting part 210 and a limiting part 220 connected with each other, the abutting part 210 is arranged in the slot 320a and abuts against the bottom of the slot 320a, the limiting part 220 is formed with a limiting slot 220a extending along the first direction, and the connecting part 320 is partially arranged in the limiting slot 220a. It can be understood that the connecting part 320 is partially arranged in the limiting slot 220a extending along the first direction, so that the two side walls of the limiting slot 220a can limit the movement of the connecting part 320 in the axial direction of the winding drum part 310, so as to hinder the abutting part 210 from separating from the slot 320a in the axial direction of the winding drum part 310.

[0049] Specifically, the abutting part 210 is partially arranged in the limiting slot 220a.

[0050] Reference Figure 4 and Figure 5 In one embodiment, the abutting part 210 comprises a connecting section 211 and a mounting section 212 connected with each other, the connecting section 211 is arranged in close contact with the side wall of the sliding slot 110, the mounting section 212 is formed with an avoiding area 210a between the side wall of the sliding slot 110, and the limiting part 220 is arranged in the avoiding area 210a. It can be understood that the connecting section 211 of the abutting part 210 is arranged in close contact with the side wall of the sliding slot 110, so that the lifting seat 200 is more stable during sliding along the first direction, and the avoiding area 210a is arranged between the mounting section 212 and the side wall of the sliding slot 110, so as to facilitate the installation of the limiting part 220.

[0051] Specifically, the mounting segment 212 is arranged in the slot 320a, the mounting segment 212 is connected with the limiting member 220, and is arranged in the limiting slot 220a.

[0052] As shown in Figure 3 and Figure 4 In some embodiments of the utility model, the limiting member 220 is connected with the part of the abutting member 210 arranged in the slot 320a, the limiting member 220 is provided with an anti-skid convex 221, and the anti-skid convex 221 abuts against the slot wall of the slot 320a. It can be understood that when the user suddenly applies external force to the lifting seat 200, so that the abutting member 210 slides upward along the first direction under the action of the external force, because the slot wall of the slot 320a abuts against the anti-skid convex 221, the friction between the limiting member 220 in the lifting seat 200 and the connecting part 320 is increased, and the possibility that the abutting member 210 is separated from the slot 320a of the connecting part 320 in the process of upward movement of the lifting seat 200 is reduced.

[0053] The display device of the second aspect of the utility model is described below. According to the display device of the second aspect of the utility model, the display device comprises the lifting support of the first aspect of the utility model. Because the size of the lifting support in the thickness direction is relatively small, the size of the lifting device in the thickness direction can be made smaller by using the lifting support, and the space required for use of the display device is further reduced.

[0054] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
