Abstract
The utility model relates to an improved emergency standby wheel for an electric vehicle. The improved emergency standby wheel for the electric vehicle comprises a standby wheel assembly, a fixed cover, a movable cover, a connecting bar, a safety catch and a spring; the fixed sleeve is fixed on a cross bar of a big supporting frame of the electric vehicle; two ends of the connecting bar are respectively connected on a side wall of the fixed cover / the movable cover in a hinged mode, a wheel shaft of the standby wheel assembly is fixed on two side walls of the movable cover, wherein the two side walls are in a fork shape, two ends of the spring are respectively fixed on the side wall of the fixed cover / the movable cover, a safety hook of the safety catch is connected on a side wall, opposite to the side on which the spring is installed, of the fixed cover in a hinged mode, and a half shaft with a screw cap is installed on a side wall corresponding to the movable cover. The improved emergency standby wheel for the electric vehicle has the advantages that the improved emergency standby wheel is fixed on the cross bar of the big supporting frame of the electric vehicle through the fixed cover , normal running and parking of the electric vehicle are not affected, when a tire is flat, the movable cover rotates to a position under the fixed cover and is tightened through the screw cap, then the improved emergency standby wheel can replace a wheel of the electric vehicle, and the tire is protected from damage.
Description
Technical field:
The utility model relates to a kind of battery-driven car, especially relates to a kind of improved electric vehicle emergency power wheel.
Background technology:
Current, battery-driven car is used as walking-replacing tool by increasing people.If but battery-driven car breaks down in the way of advancing, as the wheel puncture, blow out or other is former thereby when causing battery-driven car normally not travel or to carry out, because the vehicle body of battery-driven car is relatively heavier, a meeting of battery-driven car being carried out repairing is extremely required great effort.Therefore, the emergency power of battery-driven car wheel almost becomes indispensable annex, but the product on present stage market is too complicated, and cost is high, has increased the weight of cyclist's burden, and this problem not yet thoroughly is resolved.
The utility model content:
The purpose of this utility model is that the improved electric vehicle emergency power that a kind of simple in structure, fitting operation is convenient, cost is low wheel is provided for the prior art weak point.
the purpose of this utility model is to realize by following measures: a kind of improved electric vehicle emergency power wheel, and it comprises the Das Reserverad assembly, it is characterized in that, also has fixed cover, movable sleeve, connecting rod, safety catch, spring, described fixed cover is comprised of pullover and body, pulloverly is dissection type hollow half-round symmetrical structure with body top, symmetrical structure is fixed by screws on the cross bar of the large support of battery-driven car, described connecting rod is positioned at fixed cover/movable sleeve both sides, the connecting rod two ends are articulated and connected respectively on the sidewall of fixed cover/movable sleeve, described movable sleeve lower end is forked, the wheel shaft of Das Reserverad assembly is fixed on forked two side, described spring is positioned on sidewall with the parallel side of Das Reserverad assembly wheel shaft, both ends of the spring is separately fixed on the sidewall of fixed cover/movable sleeve, described safety catch is by auxiliary catch, semiaxis with nut forms, auxiliary catch is articulated and connected on the sidewall of the fixed cover of mounting spring offside, semiaxis with nut is arranged on sidewall corresponding to movable sleeve, tighten with nut after auxiliary catch hooks semiaxis in line the time when fixed cover and movable sleeve.
Compared with prior art; adopted and the utility model proposes improved electric vehicle emergency power wheel; have following advantage: this product is fixed on the large support crossbeam of battery-driven car by fixed cover; do not hinder normally travelling and stopping of battery-driven car; in case during the tire deficency; movable sleeve is turned to the fixed cover below and tightens with nut, and Das Reserverad is alternative Electricmotor car wheel, and the protection tire is not damaged.This product structure is simple, it is laborsaving to install rationally, carry out, and can extend Tire ﹠ Tube and wheel hub service life, and is good through practical effect, can eliminate user's various misgivings.
Description of drawings:
Fig. 1 is an example structure schematic diagram that the utility model proposes.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment is elaborated: at an embodiment of the present utility model shown in Figure 1.in figure, a kind of improved electric vehicle emergency power wheel, it comprises: Das Reserverad assembly 1, fixed cover 2, movable sleeve 3, connecting rod 4, safety catch 5, spring 6, described fixed cover by pullover 21 and body 22 form, pullover 21 be dissection type hollow half-round symmetrical structure with body 22 tops, symmetrical structure is fixed by screws on the cross bar of the large support of battery-driven car, described connecting rod 4 is positioned at fixed cover 2/ movable sleeve 3 both sides, connecting rod 4 two ends are articulated and connected respectively on the sidewall of fixed cover 2/ movable sleeve 3, described movable sleeve 3 lower ends are forked, the wheel shaft of Das Reserverad assembly 1 is fixed on forked two side, described spring 6 is positioned at the side wall surface with the parallel side of Das Reserverad assembly 1 wheel shaft, spring 6 two ends are separately fixed on the sidewall of fixed cover 2/ movable sleeve 3, described safety catch 5 is by auxiliary catch 51, semiaxis 52 with nut forms, auxiliary catch 51 is articulated and connected on the sidewall of the fixed cover 2 of mounting spring 6 offsides, semiaxis 52 with nut is arranged on the sidewall of movable sleeve 3 correspondences, tighten with nut after auxiliary catch 51 hooks semiaxis in line the time with movable sleeve 3 when fixed cover 2.
The utility model is work like this: this product is fixed on the cross bar of the large support of battery-driven car, and movable sleeve and Das Reserverad assembly are strained by spring force, and Das Reserverad can not contact with ground.When electric vehicle tire is pricked, the elastic force that first overcomes spring rotates movable sleeve, movable sleeve rotates around fixed cover by connecting rod, when fixed cover and movable sleeve in line the time, make auxiliary catch hook after button tightening nuts again, movable sleeve and fixed cover form an integral body, then prop up large support, the Das Reserverad kiss the earth, electric vehicle tire soars liftoff, so just can easily carry out.
The above has described embodiment of the present utility model by reference to the accompanying drawings; the structure that embodiment provides does not consist of restriction of the present utility model, and in this area, those skilled in the art make within the scope of the appended claims various distortion or revise all in protection domain.
