Electric bicycle capable of controlling self-balancing

Abstract

The utility model relates to the technical field of electric bicycles, and discloses a self-balancing control electric bicycle which comprises a frame, a driving assembly and a saddle are arranged on the top of the frame, and a fixed connection plate is fixedly connected to the side wall of the frame. According to the chain oiling device, the electric push rod extends through the timing switch, so that lubricating oil flows onto a chain after passing through the oil discharge pipe when air in the air cavity is pressed into the oil storage box, and therefore regular oiling and oiling of the chain can be achieved; the problem that the chain is excessively worn due to oil shortage caused by the fact that an electric bicycle user forgets to coat the chain with oil for a long time is solved; when the rainwater sensor senses that rainwater exists on the saddle, the miniature air pump is turned on, external air is fed into the heating pipe to be matched with the heating piece to be heated, then the air is blown to the saddle from the air blowing head, air blowing and water removal on the saddle can be achieved, and therefore the rainwater on the saddle can be removed when it rains; the trouble that a user of the electric bicycle for controlling self-balance needs to find a rag to wipe rainwater is saved.

Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to a self-balancing electric bicycle. Background Art

[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a battery as an auxiliary energy source and is based on an ordinary bicycle and is equipped with a motor, controller, battery, handlebars and other operating components and a display instrument system.

[0003] Existing self-balancing electric bicycles can achieve automatic balance through built-in sensors and control systems. Such bicycles are usually equipped with an electric drive system that can automatically adjust the speed and direction according to the rider's movements and changes in the center of gravity, making riding more stable and comfortable. The working principle of the self-balancing electric bicycle is mainly based on control theory and dynamics. By constantly monitoring the rider's posture and the vehicle's tilt angle, the sensor can obtain relevant data in real time and transmit it to the control system. The control system analyzes and calculates based on these data, and then controls the electric drive system to adjust the vehicle's balance state to keep it upright or move according to the rider's instructions. The chain of the common self-balancing electric bicycle needs to be lubricated regularly during use, but users tend to forget to lubricate the chain, which makes the chain prone to lack of oil and other components wear; and when it rains while the self-balancing electric bicycle is placed, when rain falls on the seat, the user needs to find a rag to wipe the rain off the seat, making the electric bicycle inconvenient to use. For this reason, we propose a self-balancing electric bicycle. Utility Model Content

[0004] The utility model aims to provide a self-balancing electric bicycle to solve the problems in the above background technology that users tend to forget to apply lubricating oil to the chain and find it inconvenient to find a rag to wipe rain water off the seat.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the time set by the timing switch of the utility model arrives, the electric push rod extends to push the piston to the left, so that the air inside the air cavity enters the oil storage box through the one-way valve 2. After the air in the oil storage box increases, the lubricating oil in the oil storage box is discharged to the porous plate through the oil discharge pipe, and then the lubricating oil flows to the chain through the oil rubbing fluff, so that the chain can be regularly oiled, avoiding the problem of the electric bicycle user forgetting to oil the chain for a long time, resulting in the lack of oil and excessive wear of the chain, so that the chain can be lubricated in time;

[0017] 2. After the utility model collects the rain data on the top of the seat through the rain sensor, the data is transmitted to the data processor, and then the data processor turns on the micro air pump to send external air into the heating tube to cooperate with the heating plate for heating. At the same time, the telescopic column is extended to make the displacement part move upward and then move out from the top of the fixing part. Then the heated air is blown onto the seat from the blowing head after passing through the extended spiral tube, which can realize the blowing and dehydration of the seat, so that the rain on the seat can be cleaned when it rains, saving the trouble of the user of the self-balancing electric bicycle to find a rag to wipe the rain.
