Description

Suspension type battery compartment of electric motor tricycle

Technical Field

The utility model relates to a battery compartment technology of an electric motor tricycle frame, in particular to a suspension battery compartment of an electric motor tricycle.

Background

The electric motor tricycle frame is generally of a two-layer frame structure and comprises an upper frame, a lower frame, a main beam, a rear wheel support, pedals and a bumper; the upper frame and the lower frame are rectangular plane frames and are horizontally arranged; the front part of the upper frame is overlapped above the rear part of the lower frame, and a plurality of straight upright posts are welded between the bottom surface of the side beam of the upper frame and the upper surface of the side beam of the lower frame, so that a bearing frame is formed; the main beam is fixed in the middle of the front end of the lower frame; the number of the rear wheel supports is four, and two rear wheel supports are respectively fixed on the bottom surface of the side column at the rear part of the upper frame; the bumpers are fixedly arranged on two sides of the main beam; the pedal plate is fixed on the upper surface of the front part of the lower frame (see fig. 1, wherein 1 is the upper frame, 2 is the lower frame, 3 is the main beam, 4 is the rear wheel support, 5 is the bumper, and 6 is the pedal plate). During specific installation, the supporting shaft of the front wheel is sleeved in the front wheel shaft sleeve at the upper part of the main beam, the rear wheel damping supporting seat is installed in the rear wheel supporting seat, and parts such as a motor, a battery, a control panel and the like are installed in a bearing frame formed by overlapping parts of an upper frame and a lower frame; thus, a basic frame of the electric motor tricycle is formed. In general, a driver seat is provided on an upper surface of a front portion of an upper frame, and an operator sits on the driver seat to operate the electric motor tricycle.

As previously mentioned, the "three-electric" (i.e., motor, battery and electric controller) of the electric motor tricycle is fixedly mounted within the load-bearing frame, wherein the battery is the component of the "three-electric" in which both volume and weight are greatest. To prevent the battery from being damaged and to facilitate installation and debugging, the front portion of the carrying frame directly under the driver seat is usually provided as a battery compartment. Because the damping system of the electric motor tricycle is simpler, the damping effect is poor, and when the electric motor tricycle runs on a rugged road, the battery can jump up and down in the battery bin due to strong vibration caused by jolting. On one hand, the strong inertial impact force formed by the up-and-down jumping of the battery directly acts on the bearing frame, so that the bearing frame is easy to deform or crack; on the other hand, the violent vibration formed by the up-and-down jumping of the battery easily causes the internal structure of the battery to change, so that the internal short circuit or open circuit of the battery is caused. Obviously, either or both of the above conditions will seriously affect the normal operation of the motor tricycle and seriously cause accidents. If the battery is rigidly fixed in the battery compartment, vibration generated when the motor tricycle runs on a bumpy road is directly transmitted to the inside of the battery, and the internal structure of the battery is easily changed, so that the inside of the battery is short-circuited or broken.

Obviously, the battery compartment of the electric motor tricycle in the prior art has the problems that the bearing frame is easy to deform or crack, and the internal short circuit or open circuit of the battery is easy to cause.
