DETAILED DESCRIPTION

[0021] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] See also Figures 1 to 5 The support structure 100 provided in the first embodiment of the utility model is used to be connected between the frame 220 and the wheel 210, and includes: at least one guide sleeve 10, at least one lower mounting seat 20 and at least two sliding members 30.

[0026] Among them, the guide sleeve 10 is used to connect the frame 220; the lower mounting seat 20 is used to connect the wheel 210; one end of the sliding member 30 is connected to the lower mounting seat 20, and the other end is slidably arranged relative to the guide sleeve 10, and at least one of the sliding members 30 can form a shock absorber with the guide sleeve 10 to absorb vibration.

[0027] The above-mentioned support structure 100 is connected to the frame 220 through the guide sleeve 10, and is connected to the wheel 210 through the lower mounting seat 20, and at least one sliding member 30 can form a shock absorber with the guide sleeve 10 to absorb vibration, and the other sliding member 30 can slide relative to the guide sleeve 10. In this way, when the vehicle 200 is moving, when the frame 220 drives the upper half of the support structure 100 to receive a forward tilting force, the forward tilting force is dispersed on the two sliding members 30, avoiding the force point on one shock absorber, thereby avoiding the risk of oil leakage caused by the increase in the gap between the sliding member 30 and the guide sleeve 10 that form a shock absorber with the guide sleeve 10.

[0028] It should be noted that, in the present embodiment, at least one of the sliding members 30 can form a shock absorber with the guide sleeve 10 to absorb vibration, which means that each sliding member 30 can form a shock absorber with the guide sleeve 10, or a part of the sliding members 30 and the guide sleeve 10 form a shock absorber, and a part of the sliding members 30 can only slide relative to the guide sleeve 10 for guiding. In this way, it can also cooperate with the shock absorber to achieve the effect of dispersing the forward force.

[0029] Specifically, see Figures 3 to 5 In this embodiment, the support structure 100 includes a guide sleeve 10, a lower mounting seat 20 and two sliding members 30, and the two sliding members 30 and the guide sleeve 10 form a shock absorber, so as to better achieve the shock absorption effect; at the same time, the guide sleeve 10 and the lower mounting seat 20 are respectively installed with the frame 220 and the wheel 210, which facilitates the overall assembly of the entire vehicle body.

[0030] It can be understood that when the shock absorber is formed by assembling the guide sleeve 10 and the sliding member 30, the guide sleeve 10 is used as the outer rod of the shock absorber, and the outer rod is provided with shock-absorbing oil, and the sliding member 30 is used as the inner rod 33 of the shock absorber, including a sliding rod 31, an elastic member 32 and an inner rod 33, the sliding rod 31 is slidably arranged relative to the guide sleeve 10, and the elastic member 32 is arranged in the sliding rod 31 and supported on the inner rod 33, so that when the vehicle body is vibrated during the walking process, the sliding rod 31 slides relative to the guide sleeve 10, and the elastic member 32 is compressed to achieve the effect of shock absorption. When the sliding member 30 is used only as a sliding rod, that is, it is set in a rod shape, can slide relative to the guide sleeve 10, and is used as a guide in conjunction with a shock absorber.

[0031] Among them, when only one guide sleeve 10 is set, at least two installation cavities 12 are formed in the guide sleeve 10, and a sliding member 30 is slidably set corresponding to one installation cavity 12. Therefore, through the setting of multiple installation cavities 12, each sliding member 30 can slide relative to one installation cavity 12, so as to be able to cooperate with the cavity wall of the installation cavity 12 and be supported by the cavity wall of the installation cavity 12 to avoid skewing during the sliding process.

[0032] See also Figure 1 and Figure 2 In one embodiment of the utility model, the support structure 100 is applied to a unicycle. In other embodiments, the support structure 100 can also be applied to vehicles 200 such as bicycles, electric vehicles, and motorcycles.

[0033] Among them, when the support structure 100 is applied to a wheelbarrow, the wheelbarrow includes a frame 220 and a hub motor wheel assembly. The frame 220 is arranged above the hub motor wheel assembly. In order to achieve installation with the frame 220, a connecting ear 11 is provided at one end of the guide sleeve 10 close to the frame 220. The connecting ear 11 is used to connect with the frame 220. In this way, by setting the connecting ear 11, it is easy to achieve connection with the frame 220.

[0034] The mounting ears and the frame 220 may be mounted by threaded connection or by welding, which is not limited here.

[0035] Furthermore, the support structure 100 of this embodiment is set on the side of the hub motor wheel assembly when it is set. The power supply 230 also needs to be set on the unicycle. Therefore, in order to facilitate the installation of the power supply 230, a mounting hole 13 is provided on the guide sleeve 10, so that the power supply 230 can be installed through the mounting hole 13, so as to realize the setting of the power supply 230 of the unicycle on the side of the hub motor wheel assembly.

[0036] Among them, the lower mounting seat 20 of this embodiment includes an upper mounting portion 21 and a lower mounting portion 22, the upper mounting portion 21 forms a first mounting position 211 with multiple sliding members 30, and the lower mounting portion 22 forms a second mounting position 221 of the wheel axle of a hub motor wheel assembly, the first mounting position 211 and the second mounting position 221 are arranged vertically, and the upper mounting portion 21 and the lower mounting portion 22 are arranged integrally, thereby facilitating the molding of the entire lower mounting seat 20.

[0037] See also Figure 1 and Figure 2 In a second embodiment, the utility model further provides a vehicle 200 , including wheels 210 , a frame 220 and the above-mentioned support structure 100 .

[0038] The vehicle frame 220 is located above the wheel 210 ; the guide sleeve 10 in the support structure 100 is connected to the vehicle frame 220 , and the lower mounting seat 20 in the support structure 100 is connected to the wheel 210 .

[0039] In this way, by setting at least two sliding members 30 in the support structure 100, when the rider rides the vehicle 200, the force in the support structure 100 can be dispersed on multiple sliding members 30, so as to reduce the risk of oil leakage of the shock absorber composed of the sliding member 30 and the guide sleeve 10, so that the riding of the vehicle 200 can be more stable.

[0040] Specifically, the vehicle 200 in this embodiment is a unicycle, and in other embodiments it may also be a bicycle, an electric vehicle, a motorcycle, etc.

[0041] Furthermore, when a plurality of slides 30 are provided on the wheelbarrow, the slides 30 are provided along the front-rear direction of the wheel 210. Thus, the plurality of slides 30 can be arranged in parallel with the wheel 210. Compared with the arrangement of the slides 30 in parallel in the thickness direction of the wheel 210, the thickness along the thickness direction of the wheel 210 can be sufficiently reduced, thereby realizing the miniaturization of the body of the wheelbarrow.
