Abstract
The utility model relates to an auxiliary tool of a power-assisted vehicle, in particular to a backup wheel which is used after a wheel of the power-assisted vehicle is punctured. In the backup wheel of the power-assisted vehicle provided by the utility model, when a tire of the power-assisted vehicle is broken or the pressure of the tire is not enough, the power-assisted vehicle can still be pushed forward by the supporting of the backup wheel. In order to fulfill the aim, the backup wheel of the power-assisted vehicle consists of an undercarriage and a trundle, wherein the undercarriage is fixedly arranged on a back wheel axle of the power-assisted vehicle; the trundle is connected with the bottom end of the undercarriage; and when the air pressure of a back tire is not enough, the undercarriage falls down and is combined with the trundle so as to support a back wheel. The scheme has the advantages that: a deflated back tire is supported by the backup wheel; and the power-assisted vehicle can still be pushed forward as normal when the back tire is deflated.
Description
Technical field
The utility model relates to the accessory appliances of assisted vehicle, particularly the quick-fried reserve wheel of taking turns the back use of mini-motorcycle.
Background technology
Development along with society, need of work, people are more and more higher to the rate request of the vehicle, originally can be by bike, because bicycle is too slow, people begin by motorcycle, in recent years, because the promotion of environmental protection, increasing people brings into use storage battery car, and storage battery car exists a lot of advantages: 1, speed wants fast with respect to bicycle; 2, easy to operate simple, 3, environmental protection and energy saving; 4, use cost is low.No matter be storage battery car, or other assisted vehicles, because the requirement of its speed, it is more firm that their vehicle frame is generally done, himself is very heavy; But when after tire stab tire, or there is not enough air pressure, at this moment just need the car owner to push away repairing, because the back tire does not have air pressure, if car does not have under the situation of power assist apparatus like this, it is quite laboriously that the car owner shoves along, in this situation, existing way is, one looks for the people to help pushes away, the 2nd, look for the car holder.Above-mentioned two kinds of ways are any all can bring very big trouble to the car owner, if look for the people to push away, rolls because tire is subjected to the weight stone roller, and it is of no use to shift repairing place possibility back tire onto.Look for the car holder, need people that he is carried on car, car is heavy again, also is suitable trouble.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of mini-motorcycle reserve wheel is provided, when mini-motorcycle stabs tire or tire pressure deficiency, by the support of motor-car reserve wheel, still can pushing away and advance.
For finishing the foregoing invention purpose, the utility model is such realization: a kind of mini-motorcycle reserve wheel, and it is characterized in that: it is made up of alighting gear and castor, and described alighting gear is fixedly mounted on the trailing wheel vehicle bridge of mini-motorcycle; Described castor is connected with the bottom of alighting gear; When the back air pressure was not enough, alighting gear fell, and unites with castor and props trailing wheel.This scheme does not have to support during gas by incite somebody to action the back tire at the reserve wheel; And then tire does not have still can normally carry out under the situation of gas after being implemented in.
Technique scheme is done further refinement, and described alighting gear is made up of support and rotation support, and described support is connected by adapter shaft with the rotation support.Also be provided with extension spring between described support and the rotation support, the opening direction of described extension spring is opposite with the working direction of car, captives joint with support in the upper end of extension spring, captives joint with the rotation support in the lower end.Support is by on the bolt vehicle bridge, and the rotation support is connected with frame bottom; The junction is provided with extension spring simultaneously; Can make in rotation and support the not time spent, rotate around frame bottom, from playing ground, during use, rotation support and your support are on same straight line; Thereby prop up car body.
Technique scheme is done further to improve; Described alighting gear is two, is fixedly mounted on respectively on two vehicle bridge of mini-motorcycle trailing wheel.Described castor can be two, connects by connection bearing.More stable for this patent is used, we can load onto two alighting gears respectively on two vehicle bridge of mini-motorcycle trailing wheel, thus the stabilization of playing.
Technique scheme is done further to improve; Described castor is a rubber wheel.Advantages such as the use rubber wheel can not blown out, and cost is low, and is easy for installation.
Description of drawings
Fig. 1 is a running condition scheme drawing of the present utility model.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
In order further to illustrate structure of the present utility model, its effect advantage is described, the utility model is further introduced below in conjunction with accompanying drawing.
As shown in the figure, what draw among the figure is a quick-fried mini-motorcycle latter half of tire, wherein tire 1 is fixed on the vehicle bridge 7 behind the mini-motorcycle, the utility model mini-motorcycle reserve wheel is fixed on the car sedan-chair 7, mini-motorcycle reserve wheel is to be made of support 3, rotation support 4 and castor 5, on the vehicle bridge after described support 3 is fixed on by bolt or other fasteners before the tire, rotation support 4 is connected with support 3 by a rotating shaft 41, and rotation is supportted 4 and can forwards be rotated around this rotating shaft 41; Also be provided with an extension spring 6 between rotation support and support, an end of extension spring 6 is fixed in the rotation support 4, and the other end is fixed on the support 3, and its effect is when using when taking turns less than mini-motorcycle reserve, this extension spring 6 of earthing will be able to being rotated and support 4 pull-ups; Can not influence normally advancing of mini-motorcycle.
In order to make stability of the present utility model better, do on our the superincumbent basis further to improve, on the opposite of above-mentioned support 3 again on the vehicle bridge, load onto second support 3 ' and the second rotation support 4 ', rotation the support 4 and second rotation support 4 ' all in this programme is to bent intermediate, its end points is handed on castor 5, and is connected with castor 5 by bearing 51.
