Abstract
The utility model relates to an emergency power assistant wheel for an electric bicycle, which comprises a fixed bracket, a lifting bracket, and a small-diameter wheel. The fixed bracket comprises a hollow tube provided with a transverse pin hole, a spring pin matching with the transverse pin hole, and a longitudinal connecting plate which is connected with the hollow tube and is provided thereof with connecting holes. The lifting bracket is a round tube matching with the hollow tube, and at least two lifting holes matching with the transverse pin holes are formed on the round tube. The lower part of the lifting bracket is connected with the small-diameter wheel. The emergency power assistant wheel can be used in time in the case of tyre burst of the electric bicycle to reduce troubles; and has the advantages of simple structure and convenient operation.
Description
Technical field
The utility model relates to the emergent power-assist wheel of a kind of battery-driven car.
Background technology
At present, fuel price skyrockets, and can not in time supply sometimes, and queuing takes number oiling to become ordinary affair.Easy to use, fast speed advantage that battery-driven car has, and can remove this irritating step of oiling from, so the Occupation coefficient of battery-driven car is growing.Simultaneously, undeniable is widespread use along with battery-driven car, and variety of issue is also following, and the broken tire of gas leakage is one of them, and this problem is difficult to prediction, allows feel helpless behind the broken tire of user.
After the breakage of battery-driven car tire, because storage battery weight is bigger, user's difficulty that moves ahead is carried out consuming one's strength reluctantly, also causes the damage once more of tire easily.The wheel hub that has is in the market made of aluminum alloy, as runs into the tire explosion, also can make the wheel hub distortion, can bring very big trouble to the user.May reduce some inconvenience if can add a spare tyre to battery-driven car, but the battery-driven car volume is little, adds a spare tyre inconvenience, also dismantling devices will be arranged, cumbersome, operability is not strong.How to address the above problem becomes current needing to be resolved hurrily.
The utility model content
The purpose of this utility model is to provide a kind of battery-driven car power-assist wheel of meeting an urgent need, and it is simple in structure, and is easy to operate; After battery-driven car is blown out, can in time use, reduce trouble.
The utility model is by the following technical solutions:
A kind of battery-driven car power-assist wheel of meeting an urgent need, comprise fixed support, lifting support and minor diameter wheel, described fixed support comprises hollow tubular, the spring pin that cooperates with described horizontal pin-and-hole and the vertical connecting panel of captiveing joint with hollow tubular that is provided with horizontal pin-and-hole, and this connecting panel is provided with connecting bore; Described lifting support is a pipe that cooperates with described hollow tubular, which is provided with at least two lift spans that mate with horizontal pin-and-hole; Described lifting support bottom connects a minor diameter wheel.
Described lifting support bottom captive joint one wheel stand, the minor diameter wheel is arranged on the wheel stand.
The utility model is fixedly installed on the wheel of battery-driven car by vertical connecting panel, by simple adjustment lifting support and support bracket fastened connection location, shrink the minor diameter wheel, when the tire explosion, can be by opening spring pin, minor diameter wheel automatic lowering lands, and spring is arranged in the pin, and bullet advances in the pin-and-hole voluntarily again, very convenient, can carry out advancing, thereby alleviate user's physical demands amount, tire damages once more when having prevented from again to carry out because of broken tire; When not required, lifting support is shunk, the minor diameter wheel lift does not influence the normal operation of battery-driven car.
The utlity model has following advantage:
The utility model is simple in structure, and is easy for installation, can be arranged on the front-wheel or the trailing wheel of battery-driven car as required, or front and back wheel installs simultaneously, simple to operate, easy to use, solves the advance problem of difficulty of the back vehicle of blowing out.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Embodiment
As shown in Figure 1 and Figure 2, a kind of battery-driven car power-assist wheel of meeting an urgent need, comprise fixed support 1, lifting support 2 and minor diameter wheel 3, described fixed support 1 comprises the hollow tubular 5 that is provided with three horizontal pin-and-holes 4, the spring pin 6 that cooperates with described horizontal pin-and-hole 4, vertical connecting panel 7 of captiveing joint with hollow tubular 5, this connecting panel 7 is provided with the connecting bore 8 and the wire way 11 of captiveing joint with the electric bicycle wheel shaft, and described hollow tubular 5 is connected after welding with spring pin 6; Described lifting support 2 be one with the pipe of 5 one-tenth sliding fits of described hollow tubular, which is provided with three with the horizontal lift spans 9 of pin-and-hole 4 couplings; Described lifting support 2 bottom captive joints one wheel stand 10, minor diameter wheel 3 is arranged on the wheel stand 10.
During use, because the rear wheel bearing amount is big, the chance of blowing out is bigger, the utility model is installed in the inboard or the outside of the trailing wheel of battery-driven car by vertical connecting panel 7.When tire is blown out after meeting battery-driven car, the lifting support 2 that can descend, spring pin 6 cooperates with the lift span 9 of the foot of lifting support 2, the height of minor diameter wheel is starkly lower than battery-driven car wheel and stressed support, make the battery-driven car trend that leans forward, reduced the stressed of minor diameter wheel 3, reduce resistance.
Claims (2)
1, the emergent power-assist wheel of a kind of battery-driven car, it is characterized in that, comprise fixed support, lifting support and minor diameter wheel, described fixed support comprises hollow tubular, the spring pin that cooperates with described horizontal pin-and-hole and the vertical connecting panel of captiveing joint with hollow tubular that is provided with horizontal pin-and-hole, and this connecting panel is provided with connecting bore; Described lifting support is a pipe that cooperates with described hollow tubular, which is provided with at least two lift spans that mate with horizontal pin-and-hole; Described lifting support bottom connects a minor diameter wheel.
2, the emergent power-assist wheel of battery-driven car according to claim 1 is characterized in that, described lifting support bottom captive joint one wheel stand, and the minor diameter wheel is arranged on the wheel stand.
