[0027] The utility model Figures 1 to 7 As shown, a novel shock-absorbing unicycle includes a hub motor 10, a U-shaped bracket 20, a frame 30, an elastic body 40 installed in the middle between the frame 30 and the U-shaped bracket 20, a battery box controller 50 installed on the top of the frame 30, and foot pedals 60 flippably installed at the lower ends of both sides of the frame 30, wherein:
[0028] The U-shaped bracket 20 is installed on both sides of the hub motor 10, and includes two side support plates 21 and a top plate 22 integrally connected to the top of the two side support plates 21. A U-shaped accommodating space 23 is formed between the two side support plates 21 and the top plate 22. The hub motor 10 is located in the accommodating space 23, and the shaft end of the hub motor 10 is connected to the lower ends of the two side support plates 21; the overall load-bearing weight of the wheelbarrow is transferred to the shaft of the hub motor 10 through the U-shaped bracket 20.
[0029] The frame 30 can be installed on the U-shaped bracket 20 in a lifting manner, and includes two side connecting plates 31 and a bearing plate 32 integrally connected to the top of the two side connecting plates 31. The two side connecting plates 31 are located outside the two side supporting plates 21. A guide mechanism 70 for assisting the frame 30 to rise and fall relative to the U-shaped bracket 20 is arranged between the side supporting plates 21 and the side connecting plates 31; the guide mechanism 70 can be in the form of a slide rail, a slide groove, or a guide rod, a guide sleeve, and can be specifically designed according to actual conditions. In this embodiment, the guide mechanism 70 includes a plurality of guide posts 71 arranged on the side connecting plates 31 and a plurality of guide grooves 72 arranged on the side supporting plates 21. The plurality of guide posts 71 can slide and cooperate with the plurality of guide grooves 72 in a lifting manner with the frame 30. Specifically, two guide grooves 72 are respectively vertically hollowed out on the two side supporting plates 21, and two guide posts 71 are respectively arranged on the two side connecting plates 31 corresponding to each guide groove 72, and the guide posts 71 are located in the guide grooves 72.
[0030] The bearing plate 32 is located above the top plate 22, and an embedding area 80 is formed between the bearing plate 32 and the top plate 22, and the elastic body 40 is located in the embedding area 80; and limiting grooves are respectively provided on the upper surface of the top plate 22 of the U-shaped bracket 20 and the lower surface of the bearing plate 32 of the frame 30 corresponding to the elastic body 40, and the two ends of the elastic body 40 are correspondingly embedded in the limiting grooves of the top plate 22 and the bearing plate 32, and the limiting grooves can prevent the elastic body 40 from being squeezed and deformed to cause position displacement, thereby improving its installation stability. The two ends of the elastic body 40 can also be fixed between the top plate 22 and the bearing plate 32 by bonding, and the fixing method of the elastic body 40 can be designed according to specific circumstances.
[0031] In this embodiment, the elastomer 40 is a rubber, and the rubber is in a cubic shape. The upper and lower surfaces of the cubic rubber form surface contact with the top plate and the load-bearing plate. The cubic rubber provides sufficient elastic buffering conditions for the frame 30. Under the extrusion of the frame 30 and the U-shaped bracket 20, it produces elastic deformation, and releases elastic stress through elastic deformation of the side, filtering out vibrations caused by ground bumps; at the same time, the surface contact makes the cooperation between the frame 30 and the U-shaped bracket 20 more stable, which can effectively prevent the frame 30 from tilting and offsetting relative to the U-shaped bracket 20.
[0032] Polyurethane elastomer, also known as polyurethane PU elastomer 40, is a new type of material between plastic and rubber, with the rigidity of plastic and the elasticity of rubber;
[0033] Ulyaphthol has the following notable features:
[0034] Wear resistance: The wear resistance of PU rubber is 3 to 5 times that of ordinary rubber.
[0035] Wide hardness range: hardness ranges from Shore A10 to Shore A95.
[0036] High temperature and aging resistance: able to withstand high temperature and long-term aging.
[0037] Oil-resistant, corrosion-resistant, and solvent-resistant: suitable for various chemical environments.
[0038] Cushioning, Quieting, Shock Absorption: Excellent in reducing noise and vibration.
[0039] Low compression set: Maintains good shape and performance even during repeated use.
[0040] In addition, the elastic body 40 made of PU has the following advantages: the amount of PU used can be adjusted or PU with different densities can be designed according to the actual load of the wheelbarrow (different PU densities have different elastic supporting forces).
[0041] The specific selection method of Glue is as follows:
[0042] 1. When the load is heavy, you can choose a high-density rubber block 90 or use a plurality of rubber blocks 90 bundled together; conversely, when the load is light, you can choose a low-density rubber block 90.
[0043] 2. Use multiple 90° distributed supports of different volumes (or diameters) or densities of high-strength rubber blocks;
[0044] As attached Figure 5 As shown, the middle part uses the largest diameter or the largest volume of the rubber block 90 as the main support, and the two sides use the smaller diameter or smaller volume of the rubber block 90 as the lateral buffer support (symmetrical distribution); multiple rubber blocks 90 can also be arrayed or surrounded for distribution support, as shown in the attached Figure 6 , 7As shown. Thereby, the central part of the wheelbarrow plays a strong support, and both sides also have certain flexibility and cushioning, so that the wheelbarrow can form support stress compensation for the body tilt gravity during turning or tilting, which is similar to the lateral support function of the car driving seat, so as to improve the riding comfort of the rider and improve the driving balance of the wheelbarrow. In addition, the distributed support of multiple high-density rubber blocks 90 with different densities can also play the above-mentioned effect, such as placing the high-density rubber block 90 with the largest density in the center, and other high-density rubber blocks 90 with smaller density are distributed on its outside. In short, the density, volume, number of high-density rubber blocks 90 and distribution mode of high-density rubber blocks 90 can be adjusted according to the actual load-bearing condition of the wheelbarrow, and the above adjustment factors (density, volume, number of high-density rubber blocks 90 and distribution mode) can be matched with each other to achieve the best product experience effect.
[0045] It should be noted that the elastomer 40 can also be in the form of a spring, a cylinder or an oil cylinder. When a spring, a cylinder or an oil cylinder is used, a corresponding damping device is configured to cooperate with the elastomer 40 to achieve a shock absorbing effect. The selection of the damping device is a conventional technical means and will not be elaborated here.
[0046] The footrest 60 includes a connecting portion 61 and a pedal portion 62. The connecting portion 61 is fixedly connected to the lower end of the connecting plate of the frame 30, and the pedal portion 62 can be flipped and hinged to the lower end of the connecting portion 61 relative to the connecting portion 61. When the wheelbarrow is not in use, the pedal portion 62 can be flipped and folded relative to the connecting portion 61 to be close to the connecting plate to reduce the occupied space.
[0047] The design focus of the utility model is that a wheelbarrow is formed by combining a hub motor, a U-shaped bracket, a frame, an elastic body, a battery box controller and a foot pedal. The wheelbarrow arranges the elastic body at a middle position between the U-shaped bracket and the frame. Compared with the traditional wheelbarrow in which the shock absorbers are arranged on both sides, this arrangement not only reduces the number of parts, simplifies the assembly process and reduces the production cost; at the same time, the elastic body can be adjusted according to the actual load-bearing conditions to adjust its shock-absorbing performance; moreover, the wheelbarrow is small in size and light in weight, and is easy to transport and store.
[0048] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
