Problems solved by technology

[0002] In the case of decreasing energy and high prices, energy-saving means of transportation have gradually become popular. Among them, bicycles are the most popular in recent years because they have the advantages of both sports and leisure. General bicycles have a certain length, so no matter driving Or it is inconvenient to carry when riding a car. For this reason, some operators have developed a folding bicycle, which is commonly known as a small folding bicycle. The bicycle can be bent and reduced in size by pulling the folder, and it can be placed in the trunk of a car or carried on it. It can be used as a means of transport for transportation, so that it can return to its original shape after arriving at a fixed point for riding. Although this small folding bicycle has the advantage of being easy to carry, it must consume a lot of effort to complete the action of pulling and folding. For women and children with less strength, it is obviously an unsuitable structure. Therefore, a bicycle that can be automatically and easily reduced for easy carrying is a very urgent problem to be solved at present.

Embodiment Construction

[0027] In order to understand the structure of the present invention and the effect that can be achieved more easily, the accompanying drawings are described as follows.

[0028] See first Figure 1 to Figure 3 , the present invention mainly extends a symmetrical shaft tube 2 backwards on the two sides of the seat tube 11 above the front fork 1 respectively. A cover 31 is set, and a rack 21 is set at the bottom of the biaxial tube 2, and a motor 5 is set at the rear fork 4, and the motor 5 is connected to a battery (not shown) with a power line, and the battery It can be arranged at a suitable place on the vehicle frame, and the axis of the motor 5 is connected with the speed change gear 61 of a driving gear set 6. At the same time, two sides of the speed change gear 61 are respectively connected with a pinion 62, and the pinion 62 is connected to the two shafts. The gear rack 21 at the bottom of the pipe 2 is engaged with each other, and the motor 3 can operate in forward an...

Abstract

The invention provides an electric telescopic bicycle, wherein, symmetric axle tubes respectively extend backwards along two sides of a seat tube above a front fork of the bicycle; the two axle tubes pass through an axle tube sleeve, and a seal sleeve is sheathed on the tail end of the two axle tubes; the bottoms of the two axle tubes are equipped with gear racks; the rear fork of the bicycle is equipped with a motor; the motor is connected to a battery through a power line, and the axle center of the motor is connected with a driving gear set; and the driving gear set is meshed with the gear racks on the bottoms of the two axle tubes. In the invention, after starting the motor to run, the driving gear set drives the axle tubes to move forwards and backwards so as to achieve the purpose of telescoping the bicycle.
