Electric power mechanism with shock absorption performance for folding electric vehicle

Abstract

The invention discloses an electric power mechanism with the shock absorption performance for a folding electric vehicle. The electric power mechanism can achieve integral shock absorption through a shock absorption module, buffering and shock absorption can be realized by the aid of an inner buffering assembly of the electric power mechanism, so that the shock absorption capacity and the shock absorption effect are improved; and a sliding shock absorption mode is adopted in the inner buffering assembly, the sliding with a certain damping coefficient between a buffering sliding base and a buffering fixing sliding rail and edge sloping ways arranged on the two sides of a middle horizontal sliding way and inclined towards the inclined upper part are utilized and a rubber sleeve with an elastic capacity are matched, so that the shock absorption performance can be effectively improved, and the buffering sliding base can be buffered in a sliding mode within a certain range. According to theelectric power mechanism, an electric power module is arranged right above a rear wheel frame and is positioned behind a saddle of the vehicle, a vehicle body can be conveniently folded, so that theshock absorption module can be used for shock absorbing for a rider and shock absorbing for the electric power module, so that the service life and reliability of the electric power module can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric bicycles with a small wheel diameter (below 20 inches), in particular to an electric power mechanism with shock-absorbing performance for a folding electric vehicle, which belongs to the folding function and conforms to the 2018 new national standard (GB17761-2018) electric bicycle. Background technique [0002] For electric bicycles, its shock absorption performance not only affects comfort, but also is crucial to the protection performance of electric power such as batteries. At present, for folding electric bicycles, it includes the following types, one is as figure 1 As shown, the electric power module of the folding car is arranged in the middle of the car body, which makes the car body grow and is not easy to fold; it is not compatible with the shock absorption system; the car body is too long and the geometric structure is weak; the second is as follows figure 2 As shown, the electric p...

At present, for folding electric bicycles, it includes the following types, one is as figure 1 As shown, the electric power module of the folding car is arranged in the middle of the car body, which makes the car body grow and is not easy to fold; it is not compatible with the shock absorption system; the car body is too long and the geometric structure is weak; the second is as follows figure 2 As shown, the electric power module is arranged in the middle and front part of the car body. Although the wheelbase is short and also supports the shock absorption system, the space of the battery module is small, and the battery capacity cannot be reasonably arranged; the third is as follows: image 3 As shown, the electric power module is arranged at the rear of the vehicle body, and the arrow is fixed on the vehicle body without a buffer structure, so that the place receives direct and more obvious vibration, and the frame is prone to fatigue damage and breakage

[0003] In the above situations, for the electric power module, it is either inconvenient to fold, or it is difficult to realize the shock absorption performance of the electric power module. Moreover, for the folding electric vehicle, it has higher requirements for the shock absorption effect of the electric power. If The shock absorption effect of electric power is not good, it is easy to cause damage to the internal battery or poor contact, the structure of the battery housing is easily damaged, and the control circuit board is also prone to loosening
