Swing arm combination type electric bicycle emergency wheel group

Abstract

Disclosed is a swing arm combination type electric bicycle emergency wheel group which can be applied to the auxiliary carrying under the emergency conditions of flat tires and locked wheels of an electric bicycle. The structure is simple, the use is convenient, the swing arm combination type electric bicycle emergency wheel group can be arranged along with the bicycle, and the problem that the carrying is difficult in case of any emergency of the electric bicycle is effectively solved. The swing arm combination type electric bicycle emergency wheel group is characterized by being formed by two separate wheel frames; each wheel frame structure comprises a body, a swing arm type connecting rod and a rolling wheel; each rolling wheel is arranged inside the corresponding wheel frame body through a rolling wheel shaft; each swing arm type connecting rod is arranged at one end of the corresponding wheel frame body through a swing arm shaft; each connecting rod is provided with a locking head which is tightened through threaded match; the other end of each wheel frame body is provided with a clamping groove which is matched with the corresponding connecting rod. During normal driving of the electric bicycle, each swing arm type connecting rod is folded on one side of the corresponding wheel frame body and accordingly the occupied area is small and the storage is convenient and each swing arm type connecting rod is unfolded outward under the emergency conditions of the flat tires or the locked wheels of an electric bicycle to enable the corresponding wheel frame to be in head-to-tail connection with the corresponding clamping groove formed in the corresponding wheel frame body through the corresponding locking head arranged on the corresponding connecting rod to be combined into a closed frame wheel group and accordingly the auxiliary carrying of the electric bicycle is implemented.

Description

technical field [0001] The invention relates to an electric bicycle emergency wheel set in the form of a swing arm combination, which can be used for auxiliary transportation of the electric bicycle in sudden situations such as tire leakage and wheel lock, can be equipped with the vehicle, and effectively solves the problem of electric bicycles in emergency situations. Difficult handling in case of emergency. Background technique [0002] With the development and popularization of electric bicycle technology, electric bicycles have gradually become an indispensable means of transportation for the people. As of the first half of 2014, the number of electric bicycles in China has exceeded 200 million. Electric bicycles are famous for their convenience and low carbon , low price and many other advantages have developed into a new industry in recent years. However, with the passage of time, some problems and shortcomings of electric bicycles have gradually become prominent. Thes...

Problems solved by technology

[0004] In order to solve the problem that electric bicycles on the market are not equipped with auxiliary emergency devices and are difficult to carry when encountering unexpected situations such as tire damage or wheel lock, a swing arm combined emergency wheel set for electric bicycles is invented, which is characterized by: The wheel set is composed of two separate wheel frames. The single wheel frame structure includes three parts: the body, the swing arm connecting rod and the roller. The roller is installed inside the wheel frame body through the roller shaft, and the swing arm connecting rod is installed on the At one end of the wheel frame body, there is a locking head on the connecting rod that is tightened by thread, and at the other end of the wheel frame body, there is a card slot that matches the connecting rod. When not working, the swing arm type connecting rod is folded on the wheel frame On one side of the main body, when it is in working condition, the swing arm type connecting rod is opened outwards, and the two wheel frames are connected end to end with the card slot on the wheel frame body through the locking head on the connecting rod to form a closed frame wheel set , fix the damaged tire in the middle of the frame-shaped wheel set, the connecting rod is responsible for bearing the body weight, and the auxiliary handling of the electric bicycle is realized by the rollers under the wheel frame
