Description

Technical Field

[0001] The utility model relates to the technical field of traveling wheel hub systems, in particular to a traveling wheel hub system for an intelligent trolley. Background Art

[0002] Smart cars rely on a powerful and flexible wheel hub system for efficient and accurate daily transportation. The wheel hub system requires a steering drive device to control the movement mode. Different wheel structures and layouts have different steering and control methods, and have different requirements for the ground.

[0003] When the existing smart car travel wheel hub system is driven by the steering drive device to turn, the wheel is subjected to a horizontal axial torque force, and the direction of this force is constantly changing, while the force in the vertical direction remains unchanged, which makes it easy for an oblique upward force to appear at the center of the wheel, causing the drive wheel to easily leave the ground and become suspended in the air when turning, which is not conducive to the smart car maintaining stability when turning; in addition, the wheel surface on the existing travel wheel hub is usually relatively smooth and most of it is hidden in the chassis structure at the bottom of the car, so that after the wheel surface is crushed by debris, the debris is easily rolled into the chassis along with the wheel, which is more likely to interfere with the normal rotation of the wheel.

[0011] Preferably, the top end of the spring is fixedly connected to the top of the inner side of the slot, the sleeve is movably embedded in the groove via the spring, and the ball is movably embedded in the pad via the groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1.

[0023] like Figures 1 to 4 As shown, the wheel hub system of the intelligent trolley in this embodiment includes a support shaft 5, one end of the support shaft 5 is rotatably connected to the wheel 1, a cross plate 2 is provided on the outer side of the wheel 1, a cavity 18 is provided inside the cross plate 2, a scraper 16 is fixedly connected to the top of the cavity 18, a miter plate 17 is fixedly connected to the bottom of the cavity 18, an opening 15 is provided at one end of the cavity 18, a steering gear 8 is provided in the middle of the support shaft 5, a washer 9 is sleeved on the other end of the support shaft 5, a groove 14 is provided inside the washer 9, a ferrule 12 is provided inside the groove 14, a round ball 13 is movably embedded inside the ferrule 12, and a spring 11 is movably sleeved on the top of the ferrule 12.

[0024] Specifically, the function of the support shaft 5 is to connect the wheel 1 with the steering system so that the wheel 1 can turn smoothly. The wheel 1 is an electric wheel, which can be driven by the power of the battery. The length of the cross plate 2 is greater than the width of the wheel 1, so that the debris scraped off the surface of the wheel 1 can slide out from the end of the extended cross plate 2 to a position away from the wheel 1, reducing the probability of the debris being re-entered into the wheel 1. The function of the cavity 18 is to guide and divert the debris scraped off by the scraper 16, so that the debris can slide out of the cross plate 2 from the opening 15 at the end of the cavity 18 to reduce the accumulation of debris in the cross plate 2. The end face of the scraper 16 is in contact with the surface of the wheel 1, and the end of the scraper 16 is tilted downward, so that the debris scraped off by the scraper 16 can be pushed into the cavity 18 along the inclined surface of the bottom of the scraper 16, which is more conducive to the separation of debris from the surface of the wheel 1. There is a certain gap between the miter plate 17 and the surface of the wheel 1. The miter plate 17 is fixed to the cross plate 2 obliquely upward, and is mainly used to receive debris dropped from the bottom surface of the scraper blade 16, so that the debris is not easy to fall on the ground, thereby facilitating the transportation of the debris to a position away from the wheel 1. The opening 15 is used to discharge the debris collected in the cavity 18 to the side away from the wheel 1, reducing the probability of the debris being rolled into the chassis through the wheel 1. The outer wall of the steering gear 8 is also equipped with a gear drive system. The function of the pad 9 is to increase the contact area between the bottom end of the support shaft 5 and the ground, while protecting the ball 13 and reducing the wear of the ball 13. The top of the sleeve 12 is a round rod structure, which can be well adapted to the spring 11, and the bottom is a hollow ball sleeve structure, so that the ball 13 can be movably embedded in the bottom and flexibly rotated. The surface of the ball 13 is smooth, and the function of the spring 11 is to enable the sleeve 12 to push the ball 13 to the ground, so that the ball 13 maintains contact with the ground.

[0025] Furthermore, one end of the cross plate 2 is fixedly connected to a connecting rod 3, and one end of the connecting rod 3 is fixedly connected to a collar 4. The collar 4 can be removed from the support shaft 5, so that the connecting rod 3 can drive the cross plate 2 to be removed from the surface of the wheel 1, which is convenient for cleaning and replacing the scraper 16.

[0026] Furthermore, the collar 4 is sleeved and connected to the support shaft 5, and the cross plate 2 is fixedly connected to the support shaft 5 through the connecting rod 3 and the collar 4. The collar 4 can support the cross plate 2 through the connecting rod 3, so that the scraper 16 on the cross plate 2 can always maintain a close contact with the surface of the wheel 1, thereby facilitating the scraper 16 to clean the surface of the wheel 1.

[0027] Furthermore, a sleeve 6 is sleeved on the outer wall of the middle part of the support shaft 5, and a vertical rod 7 is fixedly connected to the top of the sleeve 6. The vertical rod 7 and the sleeve 6 are an integrated structure with strong rigidity, and can better transmit the torque force to the wheel 1.

[0028] Furthermore, the vertical rod 7 is fixedly connected to the steering gear 8, and the steering gear 8 is movably connected to the support shaft 5 through the vertical rod 7. After rotating, the steering gear 8 transmits the force to the support shaft 5 through the vertical rod 7 and the sleeve 6, causing the support shaft 5 to drive the walking direction of the wheel 1 to change, thereby realizing the steering of the wheel 1.

[0029] Furthermore, a slot 10 is provided at the junction of the pad 9 and the support shaft 5, and the slot 10 is communicated with the inside of the groove 14, so that the sleeve 12 can move up and down in the pad 9, and at the same time, the spring 11 pushes the sleeve 12 through deformation, so that the sleeve 12 can smoothly push the ball 13 to contact the ground, so that the support shaft 5 is subjected to a vertical force, so as to improve the stability of the wheel 1 when turning.

[0030] Furthermore, the top of the spring 11 is fixedly connected to the top of the inner side of the slot 10, the sleeve 12 is movably embedded in the groove 14 through the spring 11, and the ball 13 is movably embedded in the pad 9 through the groove 14. After being squeezed by the sleeve 12, the spring 11 will exert a downward force on the sleeve 12, pushing the sleeve 12 to stick the ball 13 to the ground, so that the support shaft 5 has a fulcrum with the ground when rotating, which is beneficial to improve the stability of the wheel 1 when rotating.

[0031] The method of using this embodiment is as follows: when the wheel hub system of the intelligent trolley turns, the steering gear 8 will be driven by the steering drive mechanism, driving the vertical rod 7 and the sleeve 6 to rotate, driving the support shaft 5 to rotate horizontally, so that the wheel 1 at one end of the support shaft 5 starts to turn, and at the same time, the ball 13 in the groove 14 of the pad 9 at the other end of the support shaft 5 will be pressed by the spring 11 on the sleeve 12 and rotate in contact with the ground, so that the other end of the support shaft 5 uses the ground as a fulcrum to drive the wheel 1 to rotate in the horizontal direction, so that the wheel 1 remains in a relatively stable state when turning, and at the same time, when the wheel 1 is walking During the process, the scraper 16 on the transverse plate 2 will slide against the surface of the wheel 1 to scrape off the debris adhered to the surface of the wheel 1 after being crushed by the wheel 1, so that the debris slides into the cavity 18 of the transverse plate 2 along the inclined surface at the bottom of the scraper 16, and at the same time, the debris sliding down from the inclined surface at the bottom of the scraper 16 will fall into the miter plate 17 below, and then slide into the cavity 18 along the inclined surface at the top of the miter plate 17, and finally, the debris collected in the cavity 18 will be pushed to the opening 15 by the debris entering the cavity 18 later, and then slide out of the slide plate from the opening 15 and fall to a position away from the side of the wheel 1.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
