Furthermore, the omnidirectional wheels and directional wheels cannot be switched between each other, which fails to meet actual needs.
A wheel mechanism is designed, including a support component, a rotating wheel component, a follower component, and a directional limiting component. The directional limiting component fixes and limits the follower component, thereby realizing the directional or omnidirectional function of the rotating wheel component. The limiting operation is achieved by the sensing cooperation of the sensing sheet and the sensor.
It effectively solves the problem of directional and omnidirectional switching of wheel mechanisms, realizes a simple and low-cost switching operation, and has market promotion potential.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of AGV technology, and in particular to a wheel mechanism and a latent traction AGV. Background Technology
[0002] The AGV (Automated Guided Vehicle) is an automated transportation device that can be hidden under the bottom of a cargo trolley. It is mainly used to tow vehicles loaded with goods, operating flexibly in limited spaces to achieve efficient cargo handling. The AGV features intelligent navigation, flexible adaptability, and safety and stability, making it suitable for scenarios such as warehouses and manufacturing. In the future, it will become more intelligent, improving the level of logistics automation.
[0003] In existing technologies, AGVs with concealed traction typically employ two omnidirectional wheels at the front, a drive mechanism in the middle, and two directional wheels at the rear. The wheel system of the material carrier typically uses two omnidirectional wheels at the front and two directional wheels at the rear. When the directional wheels on the AGV are not aligned with the directional wheels of the material carrier, and the AGV is turning while pulling the material carrier, the directional wheels of the AGV will struggle against each other, causing sliding friction with the ground and accelerating wear on the directional wheel surfaces and the ground. Furthermore, existing omnidirectional wheels support 360° rotation in any direction, while the directional wheels only support directional rotation; the two cannot be switched, thus failing to meet the actual needs of AGVs with concealed traction. Therefore, a wheel mechanism and a AGV with concealed traction are provided to solve the above problems. Summary of the Invention

[0032] Please see Figures 1-4As shown, the wheel mechanism 10 of this utility model mainly includes a support assembly 11, a rotating wheel assembly 12, a follower assembly 13, and a directional limiting assembly 14. The support assembly 11 is the main support body, which is fixedly mounted on the body of the AGV (Automated Guided Vehicle). The rotating wheel assembly 12 is rotatably mounted on the support assembly 11 and can rotate 360 degrees relative to the support assembly 11. The follower assembly 13 is rotatably mounted on the support assembly 11 and meshes with the rotating wheel assembly 12, and can rotate following the rotation of the rotating wheel assembly 12. The directional limiting assembly 14 is mounted on the support assembly 11 and can perform a fixed limiting operation on the follower assembly 13, thereby enabling the rotating wheel assembly 12 to achieve directional rotation.
[0033] Please see Figures 1-5 As shown, in this embodiment, the support assembly 11 includes a support structure 111, a guide rail 112, a first sensor 113, and a second sensor 114. The support structure 111 is fixedly mounted on the body of the lurking AGV. The guide rail 112 is fixedly mounted on the support structure 111, and the directional limiting assembly 14 is slidably mounted on the guide rail 112, with the guide rail 112 guiding the movement of the directional limiting assembly 14. The first sensor 113 and the second sensor 114 are respectively fixedly mounted on the support structure 111, and both of them sense the movement of the directional limiting assembly 14. In this embodiment, the support structure 111 includes a fixed plate 1111 and a support plate 1112. The fixed plate 1111 is fixedly mounted on the body of the lurking AGV. The support plate 1112 is vertically fixed on the fixed plate 1111, and the directional limiting assembly 14 is mounted on the support plate 1112. Specifically, the fixing plate 1111 has multiple fixing holes 11111 and multiple through holes 11112. The support structure 111 is fixedly installed on the body of the lurking AGV through the multiple fixing holes 11111. The rotating wheel assembly 12 and the follower assembly 13 pass through the fixing plate 1111 through the corresponding through holes 11112. Specifically, the first sensor 113 and the second sensor 114 are both photoelectric switches.
[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, in this embodiment, the rotating wheel assembly 12 includes a rotating support structure 121, a wheel body 122, a first bearing 123, and a first gear 124. The first bearing 123 is fixedly disposed in the corresponding through hole 11112. The rotating support structure 121 is disposed through the first bearing 123, and it can rotate 360 degrees relative to the fixed plate 1111 through the first bearing 123. The wheel body 122 is rotatably disposed on the rotating support structure 121. The first gear 124 is fixedly disposed on the rotating support structure 121 and meshes with the follower assembly 13. The first gear 124 rotates with the rotation of the rotating support structure 121, thereby driving the follower assembly 13 to rotate relative to the fixed plate 1111.
[0035] Please see Figure 6 As shown, specifically, the rotating support structure 121 includes a support base 1211, a fixed shaft 1212, and a rotating shaft 1213; the support base 1211 is the main support body; the fixed shaft 1212 is fixedly and through the support base 1211, and the wheel body 122 is rotatably mounted on the fixed shaft 1212; the rotating shaft 1213 is fixedly mounted on the support base 1211 and through the first bearing 123, and can rotate 360 degrees relative to the fixed plate 1111 through the first bearing 123; the first gear 124 is fixedly connected to the rotating shaft 1213 through a flat key, so that the first gear 124 and the wheel body 122 can respectively achieve omnidirectional rotation along the axial direction of the rotating shaft 1213 and can withstand axial force and radial force.
[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment, the follower component 13 includes a second bearing 131, a follower shaft 132, a second gear 133, and a limiting block 134. The second bearing 131 is fixedly disposed in the corresponding through hole 11112 on the fixed plate 1111. The follower shaft 132 is rotatably disposed on the second bearing 131, and can rotate relative to the fixed plate 1111 through the second bearing 131. The second gear 133 and the limiting block 134 are sequentially fixedly disposed on the follower shaft 132. The second gear 133 is meshed with the first gear 124. The first gear 124 drives the second gear 133 to rotate, thereby sequentially driving the follower shaft 132 and the limiting block 134 to rotate. The directional limiting component 14 can perform a fixed limiting operation on the limiting block 134.
[0037] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, the directional limiting assembly 14 includes a driving device 141, a sliding structure 142, at least two guide wheel structures 143, a first sensing plate 144, and a second sensing plate 145. The driving device 141 is fixedly mounted on the support plate 1112. The sliding structure 142 is slidably disposed on the guide rail 112 and is connected to the driving device 141 in a transmission manner. The driving device 141 drives the sliding structure 142 to reciprocate on the guide rail 112. At least two guide wheel structures 143 are disposed on the sliding structure 142 and can perform limiting operations on the limiting block 134, thereby realizing the directional rotation of the rotating wheel assembly 12. The first sensing plate 144 and the second sensing plate 145 are respectively fixedly disposed on the sliding structure 142 and can respectively perform sensing operations with the first sensor 113 and the second sensor 114. In this embodiment, the driving device 141 is an electric push rod; two guide wheel structures 143 are symmetrically arranged on the sliding structure 142, and the two cooperate to limit the limit block 134; in other embodiments, the number of guide wheel structures 143 can be three, four or other multiples, and the number can be set according to actual needs.
[0038] Please see Figure 8 As shown, specifically, the sliding structure 142 includes a sliding bracket 1421 and a sliding seat 1422; the sliding bracket 1421 is connected to the driving device 141, and at least two guide wheel structures 143, a first sensing plate 144, and a second sensing plate 145 are respectively fixedly mounted on the sliding bracket 1421; the sliding seat 1422 is fixedly mounted on the sliding bracket 1421 and slidably mounted on the guide rail 112. Specifically, the guide wheel structure 143 includes a guide shaft 1431 and a pulley body 1432; the guide shaft 1431 is fixedly mounted on the sliding bracket 1421; the pulley body 1432 is rotatably mounted on the guide shaft 1431 and can make a limiting contact connection with the limiting block 134.
[0039] Please see Figure 9 As shown, the present invention provides a hidden traction AGV including the wheel mechanism 10 of any of the above-mentioned components.
[0040] It should be noted that the specific working process of the wheel mechanism and the lurking traction AGV of this utility model is as follows: When the wheel mechanism 10 needs to switch from directional to omnidirectional, the drive device 141 drives the sliding structure 142 to move away from the limiting block 134 on the guide rail 112. The two guide wheel structures 143 follow the movement of the sliding structure 142 to release the fixed limiting operation on the limiting block 134, so that the first gear 124 and the second gear 133 can rotate relative to each other, thereby enabling the rotating support structure 121 to rotate 360 degrees relative to the fixed plate 111, completing the switching operation of the wheel mechanism 10 from directional to omnidirectional. When the first sensing plate 144 moves into the first sensor 113 along with the sliding structure 142, the drive device 141 stops working, thereby causing the sliding structure 142 to stop moving.
[0041] When the wheel mechanism 10 needs to switch from omnidirectional to directional, the drive device 141 drives the sliding structure 142 to move on the guide rail 112 toward the limit block 134. The two guide wheel structures 143 follow the movement of the sliding structure 142 to fix and limit the limit block 134, so that the second gear 133 engages with the first gear 124. Since the rotating support structure 121 is fixedly connected to the first gear 124, the rotating support structure 121 cannot rotate relative to the fixed plate 111, thus completing the switching operation of the wheel mechanism 10 from omnidirectional to directional. When the second sensing plate 143 moves into the second sensor 114 along with the sliding structure 142, the drive device 141 stops working, thereby stopping the movement of the sliding structure 142.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
