Problems solved by technology

Due to the shape of the frame tube and the space limitation of the frame tube, the length and width of the battery opening must be greater than the length and width of the battery if the battery is to be put into the tube through the battery opening. The opening reduces the strength of the frame tubes

Embodiment Construction

[0022] The electric bicycle of the present invention includes: a vehicle frame, wheels and handles arranged on the vehicle frame, and a vehicle frame tube is arranged on the vehicle frame, and the inner cavity of the vehicle frame tube can be used to place a battery.

[0023] The core of the present invention lies in the frame tube, and the structure of the frame tube of the present invention will be described in detail below in conjunction with three specific embodiments.

[0024] Frame tube first embodiment.

[0025] refer to figure 1 and figure 2 , The frame tube of this embodiment includes: a main tube 2 for accommodating the battery and a reinforcing tube 4 arranged on the main tube 2 .

[0026] The main body tube 2 is a hollow tubular structure, and the hollow cavity 26 thereof can be used for accommodating a battery. The shape of the main body tube 2 is elongated, so as to match with the elongated batteries on the existing market. The main pipe 2 includes fou...

Abstract

The invention provides an electric bicycle and a frame pipe of the electric bicycle. The electric bicycle comprises a frame, wherein the frame pipe is arranged on the frame. The frame pipe comprises a main pipe body which is of a hollow pipe-shaped structure, a hollow inner cavity of the main pipe body is used for containing a battery, an opening which allows the battery to be placed into the inner cavity is formed in the pipe wall of the main pipe body, a reinforcing nozzle is further arranged in a non-opening position of the pipe wall, and the length direction of the reinforcing nozzle is the same as the length direction of the main pipe body. The reinforcing pipe is arranged on the frame pipe, and therefore the strength problem caused when the opening used for allowing the battery to be placed into the inner cavity is formed in the frame pipe is solved, and meanwhile the inner portion of the reinforcing pipe can also be used for wiring of the electric bicycle so that hidden wire arrangement can be formed and the whole bicycle can be more attractive and simpler.

Description

technical field [0001] The invention relates to the field of electric bicycles, in particular to a frame tube on the electric bicycle. Background technique [0002] As a kind of green and environment-friendly means of transportation, electric bicycles are more and more widely used. The battery of the existing electric bicycle is usually installed in the frame tube of the bicycle. In order to accommodate and fix the battery conveniently, the frame tube is usually divided into two foldable parts, and the battery is placed in one of the hollow frame tubes. When taking out the battery, first fold the bicycle along the seam of the frame tube, then pull out or put back the battery from the frame tube, and then restore the bicycle to the state of use. It can be seen that the battery picking and placing process of this electric bicycle All the bicycles must be folded, which not only causes troubles in use, but also causes the structure of the frame tube to be complicated, which inc...
