[0035] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, with reference to the drawings, the preferred embodiments of the present invention will be described in detail.

[0036] The embodiment of the present invention provides a laptop stand, as Figures 1 to 4 shown. The laptop stand includes a base 1, a rotating base 2, a carrying component 3 and a rolling component 4; the rotating base 2 is rotatably mounted on the base 1, and the rotating base 2 can rotate relative to the base 1; the carrying component 3 is connected to the rotating base 2 and is used to carry and support an object.

[0037] An installation groove 5 extending along the rotation track of the rotating base 2 is provided between the rotating base 2 and the base 1, and the rolling component 4 is movably mounted in the installation groove 5; the rolling component 4 includes a mounting bracket 41 and a plurality of rolling elements 42, and the plurality of rolling elements 42 are rotatably mounted on the mounting bracket 41.

[0038] The laptop stand of the present invention can be used to support a laptop computer, etc. An installation groove 5 extending along the rotation track of the rotating base 2 is provided between the rotating base 2 and the base 1, and the rolling component 4 is movably mounted in the installation groove 5. And the rolling component 4 includes a mounting bracket 41 and a plurality of rolling elements 42, and the plurality of rolling elements 42 are rotatably mounted on the mounting bracket 41. The mounting bracket 41 can form an installation limit for the rolling elements 42, so that the relative positions of the rolling elements 42 are fixed, so that the rolling elements 42 can always be kept in a preset position, avoiding the problems of unstable rotation caused by the deviation of the ball position or the friction generated by the aggregation of the balls, and improving the rotation stability and smoothness of the rotating base 2.

[0039] An installation groove 5 extending along the rotation track of the rotating seat 2 is provided between the rotating seat 2 and the base 1, providing a stable installation path for the rolling assembly 4, thereby ensuring the stability and reliability of the rolling assembly 4 during the rotation of the rotating seat 2. This design helps to reduce the problem of rotation instability caused by the position deviation of the rolling assembly 4.

[0040] Specifically, Figure 3 and Figure 4 As shown, the mounting bracket 41 is provided with a plurality of first through slots 411, and the rolling element 42 is installed in the first through slots 411. By providing the first through slots 411 on the mounting bracket 41 and installing the rolling element 42 therein, the position of the rolling element 42 on the mounting bracket 41 can be ensured to be fixed, thereby improving the stability of the entire laptop computer bracket structure. By providing the first through slots 411, the rolling element 42 can also be assembled to the mounting bracket 41 very conveniently.

[0041] The mounting bracket 41 includes a plurality of first connecting parts 412 arranged at intervals, and adjacent first connecting parts 412 limit the first through groove 411; a first protrusion 412a is arranged on the first connecting part 412. By arranging the first connecting parts 412 at intervals, the overall rigidity of the mounting bracket 41 can be increased, and the structural strength of the mounting bracket 41 can be improved. The arrangement of the first protrusion 412a on the first connecting part 412 can provide an additional limiting effect between the rolling element 42 and the first connecting part 412. The first protrusion 412a can further limit the rolling element 42, further enhance the stability of the rolling element 42, and ensure that it will not be separated from the first through groove 411 during the rolling process. The first protrusion 412a can be an arc-shaped protrusion. Further, the mounting bracket 41 also includes an inner convex ring 42 located on the inner side and an outer convex ring 43 located on the outer side; the two ends of the first connecting part 412 are respectively connected to the inner convex ring 42 and the outer convex ring 43.

The inner side is the side of the mounting bracket 41 close to the rotation center of the rotating seat 2, and the outer side is the side of the mounting bracket 41 away from the rotation center of the rotating seat 2. More specifically, the width of the first connecting portion 412 gradually increases from the inner side of the first connecting portion 412 toward the outer side. The inner side is the side of the first connecting portion 412 close to the rotation center of the rotating seat 2, and the outer side is the side of the first connecting portion 412 away from the rotation center of the rotating seat 2.

[0042] The installation groove 5 is an annular groove surrounding the rotation center of the rotating base 1; the installation bracket 41 is annular and surrounds the rotation center of the rotating base 1. The rolling member 42 is a cylindrical roller, and the cylindrical roller is installed on the installation bracket 41 in a horizontal state. The side surface of the horizontally installed cylindrical roller serves as a rolling surface, which can provide more area of support and improve the rotational balance of the rotating base 2.

[0043] Specifically, further in combination with Figures 5 to 8 As shown, the base 1 includes a bottom plate 11 and a connecting plate 12; the connecting plate 12 is installed on the bottom plate 11; the installation groove 5 is provided on the side of the connecting plate 12 facing the bottom plate 11 and on the side of the rotating base 2 facing the connecting plate 12; the installation grooves 5 of the rotating base 2 and the connecting plate 12 are arranged correspondingly, which can provide a more abundant installation space and can also reduce the gap between the bottom plate 11 and the rotating base 2, making the structure of the laptop stand more compact. The connecting plate 12 can be installed on the bottom plate 11 by screws 20, and a connecting head 30 is rotatably installed at the middle of the connecting plate 12, and the connecting head 30 is connected to the rotating base 2 by screws 20, thereby realizing the rotational connection of the rotating base 2.

[0044] As Figures 9 to 12 shown, a second connecting portion 21 is provided on the rotating base 2, and the bearing assembly 3 includes a rotating arm 31.

The first isolation ring 6 and the first oil storage ring 7 are provided with oil storage holes 40 to store lubricating oil and reduce the rotational friction between the rotating arm 31 and the second connecting portion 21.

[0046] Further, on the side of the rotating arm 31 facing away from the second connecting portion 21, a second oil storage ring 8 and two damping rings 9 are sleeved on the connecting member 10. The two damping rings 9 are located between the first oil storage ring 7 and the second oil storage ring 8; an oil storage hole 40 is formed in the second oil storage ring 8. The two damping rings 9 are in an arc shape with a higher middle and a lower periphery, and the two damping rings 9 abut against each other on the side of their middle protrusion. The two damping rings 9 abutting against each other on the side of their middle protrusion can generate deformation elastic force, so as to provide rotational damping. The connecting member 10 includes a bolt 101 and a nut 102. Through the cooperation of the bolt 101 and the nut 102, the first oil storage ring 7, the first isolation ring 6, the damping ring 9, and the second oil storage ring 8 on both sides of the rotating arm 31 are pressed tightly.

[0047] The support assembly further includes a support plate 32. A support arm 321 is provided at the lower edge of the support plate 32, and there are two rotating arms 31. There are also two second connecting portions 21 on the rotating base 2.
