Folding electric bicycle frame and folding electric bicycle

Abstract

The invention relates to a folding electric bicycle frame. The folding electric bicycle comprises a main crossbeam, wherein a front wheel steering mechanism is arranged at the first end of the main crossbeam, a cushion support pipe is in flexible inserting connection to the second end of the main crossbeam, the main crossbeam is also pivoted to one end of a rear electric bicycle frame, and one of the main crossbeam and the rear electric bicycle frame can rotate around a rotating shaft connected with the main crossbeam and the rear electric bicycle frame relative to the other of the main crossbeam and the rear electric bicycle frame in a horizontal direction; the rotating shaft is located between the front wheel steering mechanism and the cushion support pipe, and the rear electric bicycle frame is locked through the matching of the rotating shaft and the cushion support pipe under an unfolded state. The folding electric bicycle frame disclosed by the invention is exquisite in design and simple in structure, and an original structure of a conventional folding electric bicycle is broken through; and the rear electric bicycle frame and the main crossbeam can rotate relative to each other, so that folding an electric bicycle body can be realized. Though the matching of a support casing pipe and the rotating shaft connected with the rear electric bicycle frame and the main crossbeam, the stability of the electric bicycle body under the unfolded state can be effectively realized. A whole folding structure and an unfolded locking structure are succinct, and compared with a conventional folding electric bicycle body, the folding electric bicycle frame has the advantage that the number of desired parts and components is greatly reduced.

Description

technical field [0001] The invention relates to a vehicle frame and an electric vehicle, in particular to a folding vehicle frame and an electric vehicle using the folding vehicle frame. Background technique [0002] Electric vehicles are more and more accepted by the public because of their convenience, environmental protection and other advantages. The electric vehicle is based on the structure of the existing bicycle and is modified. By adding batteries, drive systems and electronic control systems, the vehicle can be driven by electric energy to run quickly. [0003] Most traditional electric vehicles are bulky and complex in structure, and users feel that they are not very light when using them, especially in complex environments such as going up and down stairs, elevators, subways, etc., the disadvantages of traditional electric vehicles are very obvious. For a long time, many manufacturers have been lingering in the vicious circle of copying each other without breaki...

Problems solved by technology

[0006] After some folding electric vehicles are folded, the front wheels and rear wheels are on different planes or have a height difference, and the body can no longer be moved through the wheels, and manual handling is required. However, the overall structure of electric vehicles is relatively large, which makes the folded electric vehicles Car handling is more difficult

[0007] In addition, the existing folding frame is based on the original frame, so that some structures have the characteristics of folding, so as to achieve the purpose of folding, these folding frames do not break through the original frame structure of the electric vehicle, so although the The folding of the frame is realized, but the folding structure is complicated, and because the overall structure of the original frame is large, the space occupied after folding is still large, which cannot meet the requirements of miniaturization

[0008] At the same time, since the front and rear wheel mounting brackets of existing electric vehicles are often double-arm structures, this also virtually increases the lateral space of the vehicle body. After horizontal rotation and folding, the lateral space occupied is larger.

[0009] Finally, since the vehicle body is a folding structure, multiple parts are often movable, so it is necessary to set up multiple locking structures to ensure the stability of the frame when it is unfolded, and this will inevitably increase the folding frame. complexity of
