Further, the rear bottom fork is an integrated bottom fork, and the pedal middle shaft sleeve is connected to the bottom of the rear bottom fork through a screw.
Further limit, rear wheel sprocket, electronic output sprocket and foot-propelled output sprocket all adopt the aluminum alloy material to make.
Compared with the prior art, the utility model has the following advantages:
1. the foot-operated output chain wheel is meshed with the roller chain and is arranged below the seat, and the motor can be randomly arranged at other positions without being fixedly arranged below the seat.
2. The aluminum alloy material can be more durable.
3. When the electric vehicle is not powered on, a rider can drive the electric vehicle to move forward by pedaling, and when the electric output chain wheel is in a driving state, the pedals cannot rotate synchronously because the pedal-driven output chain wheel is provided with the isolator.
Drawings
Fig. 1 is a schematic view of the structure of an auxiliary pedal device of the present invention.
FIG. 2 is a schematic front view of the engagement of the foot-operated output sprocket, electric output sprocket and rear wheel sprocket with the roller chain of the present invention.
FIG. 3 is a bottom view of the integrated rear fork of the present invention.
The designations in the figures correspond respectively to: 1-roller chain, 2-foot-operated output chain wheel, 3-rear wheel chain wheel, 4-electric output chain wheel, 5-pedal middle shaft sleeve, 6-pedal middle shaft, 7-pedal, 8-rear bottom fork and 9-mounting hole.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained in the following with the accompanying drawings and the specific embodiments.
Example (b):
as shown in fig. 1-3, an electric vehicle with auxiliary pedals comprises a frame body, a rear bottom fork 8, a rear wheel, a roller chain 1 and a chain wheel, wherein one end of the rear bottom fork 8 is connected with the frame body, the other end of the rear bottom fork 8 is connected with the rear wheel, the chain wheel is divided into a foot-operated output chain wheel 2, a rear wheel chain wheel 3 and an electric output chain wheel 4, the chain wheels are made of aluminum alloy materials and can be more durable, the electric output chain wheel 4 is arranged at the installation position of the rear bottom fork 8 and the frame body, the rear wheel chain wheel 3 is connected with the rear wheel, the electric vehicle further comprises a pedal middle shaft sleeve 5 and a pedal middle shaft 6, the rear bottom fork 8 is an integral bottom fork, a pedal middle shaft sleeve 5 is fixedly connected with an installation hole 9 at the bottom of the rear bottom fork 8 through a screw, the pedal middle shaft 6 penetrates through the pedal middle shaft sleeve 5, pedal middle shaft 6 is connected with foot pedals 7 at two ends, and a foot-operated output shaft 6 is arranged on the pedal middle shaft 6 between the pedal 7 and the pedal middle shaft sleeve 5 at one side Go out the sprocket 2 foot-propelled output sprocket 2 on be equipped with the isolator, roller chain 1 meshes with foot-propelled output sprocket 2, rear wheel sprocket 3 and electronic output sprocket 4 mutually, foot-propelled output sprocket 2 is installed between rear wheel sprocket 3 and electronic output sprocket 4, when the electric motor car does not have the electricity, the car of riding on the ground can drive the electric motor car through pedal 7 and advance.
