[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0042] According to an embodiment of this utility model, a roller structure is provided; please refer to [link / reference]. Figures 1 to 9 It includes: a connecting component 1; a supporting component 2, which is movably disposed relative to the connecting component 1; a shock-absorbing component 3, which is connected to the connecting component 1 and the supporting component 2; when the supporting component 2 moves, the shock-absorbing component 3 reduces the vibration of the supporting component 2; and a driving component, which includes a reducer 4 and rollers 5 connected to the output shaft 41 of the reducer 4; at least two rollers 5 are provided; when the reducer 4 drives the rollers 5 to rotate, it drives at least two rollers 5 to rotate synchronously.

[0043] With the above configuration, one end of the shock-absorbing component 3 is connected to the support component 2, and the other end is connected to the connecting component 1. The shock-absorbing component 3 is deformed and damped. The drive component is connected to the reducer 4 through the rotating shaft. The rotating shaft drives the reducer 4. The output shaft 41 of the reducer 4 is connected to the roller 5, thereby driving the roller structure to move. By using multiple rollers 5 with smaller wheel diameters, the center of gravity of the roller structure is lowered, and the contact area between the roller 5 and the moving surface is increased, thereby making the roller structure more stable in use.

[0044] Specifically, by combining and linking multiple roller structures with a load-bearing device, an AGV (Automated Guided Vehicle) structure is formed for transportation.

[0045] In the roller structure of this embodiment, see Figures 1 to 4 The connecting component 1 includes: a first connecting plate 11, on which a connecting groove 1121 is provided; a reducer 4 passes through the connecting groove 1121; a second connecting plate 12, which is connected to the first connecting plate 11; and the second connecting plate 12 is connected to the shock-absorbing component 3.

[0046] In a specific embodiment, the connecting reducer 4 passes through the first connecting plate 11 to reduce the overall height of the roller structure, and the second connecting plate 12 connects the shock-absorbing component 3, which solves the vibration problem when the AGV is being transported.

[0047] In the roller structure of this embodiment, see Figures 1 to 4 The first connecting plate 11 includes a first plate body 111 and a second plate body 112. The first plate body 111 is located above the second plate body 112. The second connecting plate 12 is connected to the first plate body 111. A connecting groove 1121 is provided on the second plate body 112.

[0048] By placing the second connecting plate 12 at a suitable position on the first plate 111, the overall height of the roller structure can also be reduced.

[0049] With the above configuration, the first plate 111 is connected to the second connecting plate 12, and the second plate 112 is connected to the reducer 4 via the connecting groove 1121. By setting up different components to connect, the space in the horizontal direction is compressed, further ensuring that the AGV can work within the limited space.

[0050] In the roller structure of this embodiment, see Figures 1 to 4 The second connecting plate 12 is provided with a first connecting hole 121, and the shock-absorbing component 3 is inserted into the first connecting hole 121.

[0051] Specifically, the corresponding part of the shock-absorbing component 3 is installed through the first connecting hole 121. The number of first connecting holes 121 is not limited, thereby connecting multiple shock-absorbing components 3. By combining multiple shock-absorbing components 3, it is ensured that when the size of the shock-absorbing component 3 is limited, sufficient shock absorption effect can be guaranteed through multiple combinations.

[0052] Preferably, after the shock-absorbing component 3 passes through the first connecting hole 121, the threaded part of the shock-absorbing component 3 can be fitted with a bidirectional nut, thereby ensuring that the connection part of the shock-absorbing component 3 is not prone to loosening when the roller structure is running, thereby further improving the shock absorption effect.

[0053] In the roller structure of this embodiment, see Figures 1 to 4 A guide rail 13 is provided on the first connecting plate 11; a slider 23 corresponding to the guide rail 13 is provided on the support component 2; the slider 23 is slidably connected to the guide rail 13; the guide rail 13 is located on the side of the first connecting plate 11 away from the second connecting plate 12.

[0054] In a specific embodiment, the guide rail 13 is installed on the surface opposite to the second connecting plate 12 of the connecting component 1, thereby saving space and ensuring that the roller structure is within a limited height range; the guide rail 13 is provided with a sliding groove, and through the guiding action of the sliding groove and the slider 23, the moving track of the support component 2 is guided, thereby ensuring that the connecting component 1 and the support component 2 run on the guide track, thus playing a normal shock absorption role.

[0055] Specifically, at least two sliders 23 are provided. By distributing the load among at least two sliders 23, it is ensured that the moving device will not be affected by deformation or other issues due to damage to a single slider 23.

[0056] In the roller structure of this embodiment, see Figures 1 to 9 The connecting flange 6 is connected to the second plate 112;

[0057] The connecting sleeve 7 passes through the connecting groove 1121 and extends to the side of the second connecting plate 12 away from the connecting flange 6; the output shaft 41 of the reducer 4 passes through the connecting sleeve 7.

[0058] Specifically, the connecting flange 6 is snapped into the corresponding interface of the second plate 112, and the connecting sleeve 7 is bolted to the corresponding bolt hole of the second plate 112, thereby connecting the drive assembly to the connecting assembly 1. Because multiple rollers 5 are installed, the output shaft 41 of the reducer 4 needs to be lengthened accordingly. The connecting sleeve 7 increases the installation strength of the reducer 4, thus making the structure more stable.

[0059] In the roller structure of this embodiment, see Figures 1 to 7 There are two guide rails 13, which are respectively arranged on opposite sides of the connecting groove 1121; and / or, the first connecting plate 11 and the second connecting plate 12 are arranged perpendicular to each other.

[0060] In a specific embodiment, the guide rails 13 are arranged in pairs to ensure stable guidance of the support component 2. The first connecting plate 11 and the second connecting plate 12 are vertically connected to reserve installation space for the shock-absorbing components.

[0061] In the roller structure of this embodiment, see Figures 1 to 7 The support assembly 2 includes: a first support plate 21, on which a support groove 211 for avoiding the reducer 4 is provided; a second support plate 22, connected to the first support plate 21, on which a second connecting hole 221 is provided, and a shock-absorbing component 3 is disposed in the second connecting hole 221.

[0062] Specifically, when the moving parts are running, the support assembly 2 moves up and down in the horizontal direction, and the support groove 211 provides sufficient space for the reducer 4.

[0063] In the roller structure of this embodiment, see Figures 1 to 7 There are multiple second connecting holes 221, which are spaced apart; and / or, the first support plate 21 and the second support plate 22 are arranged perpendicular to each other.

[0064] Preferably, in practice, multiple shock-absorbing components 3 are connected to the corresponding second connecting holes 221, and the two support plates are vertically configured to provide space for the installation guide and shock-absorbing components 3.

[0065] In the roller structure of this embodiment, see Figures 1 to 7 There are multiple shock-absorbing components 3, which are arranged at intervals.

[0066] Specifically, by combining multiple damping components 3, sufficient damping effect can be ensured even when the size of the damping components 3 is limited. The damping components 3 are set at preset intervals to ensure that each one fully exerts its damping function.
