When the electric wheelchair runs outdoors, dust, small stones and weeds enter the wheel through the space between the spokes, and the foreign matters are clamped on the wheel shaft and even enter the hub motor to influence the normal use of the electric wheelchair.
Disclosure of Invention
The utility model aims at providing an inside foreign matter got into the wheel can be avoided to avoid the electronic wheelchair wheel dustproof construction that the wheel blocked.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an electric wheelchair wheel dustproof construction, includes in-wheel motor, in-wheel motor axial side is fixed with support wheel hub circumference side is equipped with the tire, support wheel hub comprises middle part, outer ring portion and a plurality of spoke, the spoke is connected between middle part and outer ring portion, support wheel hub keeps away from in-wheel motor's axial side and is equipped with the dust cover, dust cover circumference outer fringe shape size with outer ring portion circumference inner edge shape size is the same, be equipped with the at least three group's of mutually supporting buckle structures between dust cover and support wheel hub, buckle structure is including setting up in the buckle of dust cover rear side to and set up the cooperation groove on support wheel hub's spoke, a plurality of cooperation grooves be with the axis at middle part sets up for the annular interval at center.
Accomplish in-wheel motor and the installation of support wheel hub back, aim at the buckle of dust cover and the cooperation groove on the support wheel hub, then carry out the pressure equipment of dust cover to make buckle and cooperation groove cooperation, thereby realize the fixed of dust cover, seal the space between support wheel hub's adjacent spoke through the dust cover, in the space entering wheel between in order to avoid having the foreign matter to pass through the spoke, in order to avoid the wheel to block. Wherein, the dust cover can adopt plastics to make the buckle have certain deformation volume.
Preferably, the spoke outer axial surface is offset from the outer annular portion outer axial surface, the spoke outer axial surface is located inside the outer annular portion outer axial surface, and a receiving groove for receiving the dust cover is formed between the spoke outer axial surface and the outer annular portion outer axial surface. The above-mentioned setting is so that the dust cover can be located inside support wheel hub to avoid the dust cover edge to bulge to the wheel outside as far as possible, in order to avoid having the foreign matter card between dust cover edge and spoke, in order to improve the sealed effect of dust cover.
Preferably, the longitudinal section of the dust cover along the axial direction is arc-shaped, the inner surface of the dust cover is arc-shaped, a gap is formed between the middle part and the inner surface of the dust cover, and the spoke at least deviates from the outer ring part and has a gap with the inner surface of the dust cover. The arrangement enables the dust cover to have certain elasticity, and is convenient for matching of the buckling structure.
Preferably, the engagement slot extends axially through the spoke along the support hub. The arrangement is used for enabling the matching groove to be simple in structure and facilitating the processing of the support hub.
Preferably, the mating groove is adjacent the outer ring portion. The shape quantity at dust cover edge is bigger, more does benefit to the installation of dust cover, and as preferred, the spoke surface is sunken in order to be formed with heavy groove to wheel hub motor side, the cooperation groove is located heavy groove tank bottom and with heavy groove intercommunication. The heavy groove can be used for subtracting of support wheel hub, and it is long when the contact of buckle and cooperation groove cell wall can also be used for reducing the dust cover installation to the installation of dust cover, in order to avoid the hook card of buckle to cooperate the inslot.
The utility model has the advantages of can avoid the foreign matter to get into inside the wheel to avoid the wheel to block.
