Problems solved by technology

[0003] The existing tricycle front frame and rear frame are all firmly fixed together, and the rear frame of the whole vehicle remains stable. When turning, the vehicle is affected by the offset of the center of gravity, and the vehicle is relatively easy to rollover. In order to ensure The heavy cargo on the rear frame is firm and does not fall apart, which has high requirements on the driving skills of the driver. If the turning angle is large or the cargo loaded is large and high, a little carelessness may cause the vehicle to overturn

Embodiment 1

[0040] Such as figure 1 As shown, an electric logistics vehicle includes a front vehicle part 1 and a rear vehicle part 2. The front vehicle part 1 comprises a front vehicle frame 3, a front wheel 4 and a front vehicle body 5, the front wheel 4 is rotatably connected to the front vehicle frame 3, the front vehicle body 5 is fixedly installed above the front vehicle frame 3, and the front vehicle body 5 is far away from one end of the rear vehicle part 2 A handle 6 for controlling the direction is provided. Seat 7 is installed in front vehicle body 5 middle parts. The rear vehicle part 2 comprises a rear vehicle frame 8, a rear wheel 9 and a rear vehicle body 10. The rear wheel 9 is provided with two coaxial rotations connected to the rear vehicle frame 8, and the front wheel 4 and the rear wheel 9 form a triangular support.

Embodiment 2

[0058] The difference between embodiment two and embodiment one is: as Figure 9 and Figure 10As shown, in order to facilitate the return of the front body 5, the outer wall of the rotating shaft 11 is provided with several abutment parts 41 along its circumference, and an accommodation chamber 42 is formed between two adjacent abutment parts 41, and an elastic damping member is arranged in the accommodation chamber 42 43 , and the elastic damping member 43 abuts against the inner wall of the accommodating chamber 42 . The elastic damping element 43 is fixedly connected to the rotating part 12 . Specifically, the elastic damping member 43 is made of elastic rubber, and the two ends of the elastic damping member 43 are respectively provided with protrusions 44, and the protrusions 44 are embedded in the rotating part 12, so that the elastic damping member 43 is fixedly connected to the rotating part 12. .

Abstract

The invention relates to the field of logistics vehicles, and particularly discloses a manual control type vehicle body shaking mechanism for an electric logistics vehicle. The manual control type vehicle body shaking mechanism comprises a rotating shaft fixedly installed on a rear frame and a rotating part arranged on a front frame. The rotating part rotationally sleeves the rotating shaft. The rotating part is internally fixedly provided with a guide part. A bolt is slidingly connected into the guide part in the axial direction of the rotating shaft. An inserted connection part with an insertion hole is fixedly installed in the rotating shaft. One end of the bolt is rotationally connected with a linkage rod. The end, away from the bolt, of the linkage rod is provided with a middle part parallel to the bolt. One end of the linkage rod is embedded in the middle part and rotationally connected to the middle part. A swing arm assembly for driving the middle part to slide in the axial direction of the rotating part is rotationally connected into the rotating part. One end of the swing arm assembly is provided with a driving mechanism for driving the swing arm assembly to rotate. In the driving process, if the vehicle needs to turn a corner, a driver can change the gravity center of the front frame by controlling the inclination of the body, then the front frame is driven to rotaterelative to the rear frame, the vehicle can more easily turn a corner, and the vehicle turn-over probability is reduced.

Description

technical field [0001] The invention relates to the technical field of logistics vehicles, in particular to a manually controlled body swing mechanism for electric logistics vehicles. Background technique [0002] At present, tricycle has generally entered the production and life of the broad masses of the people owing to having the advantages of convenient loading, simple operation, low price, good quality, and durability. Such as the patent application number CN201420779772.5, the patent discloses a three-wheeled electric flatbed car, including a vehicle body, handlebars, front wheels, rear wheels and a vehicle seat, the middle part of the vehicle body is provided with a vehicle seat, the vehicle body The front portion of the vehicle is provided with a front wheel and a handlebar, the handlebar is provided with a brake, and the rear portion of the vehicle body is provided with a rear wheel. When the tricycle is running, the rear wheels are the driving wheels and the front...
