Abstract
The utility model discloses a standby wheel device for tire explosion prevention for an electric bicycle, the standby wheel device takes effect in protecting a back wheel after tire explosion of the back wheel of the electric bicycle, the standby wheel device is connected with a frame body of the electric bicycle, the standby wheel device comprise a back wheel supporting rack and a rolling wheel, and the rolling wheel is connected with the back wheel supporting rack via a rotary shaft. The standby wheel device in the utility model not only saves physical power consumption of a pusher after tire explosion of the bicycle, but also prevents rubbing of the tire in the pushing process, and reducing maintenance cost of consumers.
Description
Technical field
The utility model relates to technical field of transportation means, is specifically related to a kind of Electrical Bicycle runflat and uses spare wheel device.
Background technology
Along with China's constant development of economy; Improving constantly of people's living standard; People's trip mode also presents a new trend i.e. " quick, low-carbon (LC) "; China resident adopts battery-driven car as the vehicle more at present, and this has alleviated the urban traffic pressure to a certain extent, also meets the trip mode of low-carbon (LC) simultaneously.Battery-driven car also has inconvenience, if our electric vehicle tyre in the trip process is punctured bringing to us much simultaneously easily in the trip process; In the maintenance point progradation, because battery-driven car is provided with energy-storage battery, energy-storage battery is mostly relatively heavier with battery-driven car; Need expend a large amount of muscle power of promoter; But what is more important, after vehicle was shifted maintenance point onto, your back found that tire has suffered to rub to scrap in progradation.In sum, so not only wasted customer's muscle power, also increased the customer and got maintenance cost.
Summary of the invention
The technical matters that the utility model will solve provides a kind of Electrical Bicycle runflat and uses spare wheel device; This technical scheme has not only been practiced thrift blow out back promoter's physical demands of vehicle; Avoid tire rubbing in progradation simultaneously, reduced customer's maintenance cost.
The utility model is realized through following technical scheme:
The driving runflat is used spare wheel device; After the Electrical Bicycle trailing wheel blown out, play the effect of protection trailing wheel, spare wheel device is connected with Electrical Bicycle vehicle frame body; It is characterized in that: said spare wheel device comprises back wheeling supporting frame, roller, and roller is connected with the back wheeling supporting frame through rotating shaft.
The further Technological improvement plan of the utility model is:
Said back wheeling supporting frame is made up of link span, underframe, and link span one end is connected with the vehicle frame body, and the other end is connected with underframe, and underframe is provided with the roller mounting bracket, and the roller mounting bracket is " n " type, and roller is rotationally connected through rotating shaft and roller mounting bracket.
The further Technological improvement plan of the utility model is:
Said back wheeling supporting frame is provided with two or more rollers; Said roller is processed by nylon material.
The utility model compared with prior art has following obvious advantage:
The utility model utilizes connecting device that the fault wheel of vehicle is connected with roller, has so not only saved promoter's physical demands, and has avoided fault wheel tyre rubbing in progradation, has practiced thrift maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the utility model spare wheel device comprises back wheeling supporting frame 1, roller 2, and back wheeling supporting frame 1 is made up of link span 11, underframe 12; Link span 11 1 ends are connected with vehicle frame body (not providing in the view); The other end is connected with underframe 12, and underframe 12 is provided with roller mounting bracket 4, and roller mounting bracket 4 is " n " type; Roller 2 is rotationally connected through rotating shaft 3 and roller mounting bracket 4, and back wheeling supporting frame 1 is provided with two or more rollers 2; Roller 2 is processed by nylon material.
