Technical Field

[0001] This utility model belongs to the field of electric tricycle technology, and in particular relates to an electric tricycle cargo box lifting and self-unloading device. Background Technology

[0002] Traditional electric tricycles have a hydraulic motor directly mounted on the electric motor. When using them, you need to first put the motor in neutral, step on the brake, and then turn the speed control handle while controlling the lifting system through the lifting rod. All steps need to be performed simultaneously, making the operation cumbersome, resulting in uneven lifting speeds, unreliable performance, and even slight misoperation can damage the vehicle or the operator. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an electric tricycle cargo box lifting and self-unloading device. The lifting signal is transmitted to the integrated hydraulic pump through a hydraulic control switch. The hydraulic cylinder lifts and extends at a uniform speed, thereby driving the cargo box to achieve the state of self-unloading. The operation is simple and improves work efficiency.

[0004] The technical solution adopted by this utility model is as follows: an electric tricycle cargo box lifting and self-unloading device, including a tricycle body, a hydraulic cylinder movably installed on the bottom frame of the tricycle body, a connecting seat installed on the bottom wall of the tricycle body cargo box, the movable end of the hydraulic cylinder being movably connected to the connecting seat, a self-locking rocker arm movably installed on the bottom wall of the tricycle body cargo box, a locking hook movably installed on the rear bottom wall of the tricycle body cargo box, a self-locking pull rod movably installed on the upper end of the self-locking rocker arm, and the end of the self-locking pull rod away from the self-locking rocker arm being movably connected to the side wall of the locking hook.

[0005] The tricycle body has a limit frame installed on the bottom wall of the rear door of the vehicle body. When the vehicle body is placed horizontally, the upper end of the locking hook abuts against the bottom wall of the rear door of the vehicle body, and the locking hook is engaged in the limit frame to fix the rear door of the vehicle body.

[0006] The tricycle body is equipped with a hydraulic cylinder and an integrated hydraulic pump under the seat. One end of the integrated hydraulic pump is connected to the hydraulic cylinder, and the other end of the integrated hydraulic pump is equipped with a hydraulic oil pipe, which is connected to the hydraulic cylinder. An integrated hydraulic pump delivers oil from the hydraulic cylinder to the hydraulic cylinder through hydraulic oil pipes, thereby controlling the lifting of the hydraulic cylinder. An integrated hydraulic pump delivers oil from the hydraulic cylinder to the hydraulic cylinder via hydraulic oil pipes, thereby controlling the descent of the hydraulic cylinder.

[0007] The tricycle body has a hydraulic cylinder controller switch installed at the handlebar position, and the hydraulic cylinder controller switch is electrically connected to the integrated hydraulic pump through a switch wire.

[0008] The tricycle body's cargo box bottom wall is also equipped with a limit rod, which is located near the self-locking rocker arm. When the self-locking rocker arm is raised and rotated with the cargo box, the limit rod can limit the rotation angle of the self-locking rocker arm.

[0009] The advantages of this utility model after adopting the above structure are as follows: the lifting signal is transmitted to the integrated hydraulic pump through the hydraulic control switch, and the carriage is driven by the uniform lifting and extension of the hydraulic cylinder to realize the self-unloading state of the cargo. The operation is simple and the work efficiency is improved.

A locking hook 5 is movably mounted on the rear bottom wall of the tricycle body cargo box 13. A self-locking pull rod 6 is movably mounted on the upper end of the self-locking rocker arm 4. The end of the self-locking pull rod 6 away from the self-locking rocker arm 4 is movably connected to the side wall of the locking hook 5.

[0016] The bottom wall of the rear door of the tricycle body 13 is equipped with a limiting frame 7. When the body is placed horizontally, the upper end of the locking hook 5 abuts against the bottom wall of the rear door of the body, and the locking hook 5 is engaged in the limiting frame 7 to fix the rear door of the body.

[0017] The tricycle body 1 is equipped with a hydraulic cylinder 8 and an integrated hydraulic pump 9 under the seat. One end of the integrated hydraulic pump 9 is connected to the hydraulic cylinder 8, and the other end of the integrated hydraulic pump 9 is equipped with a hydraulic oil pipe 10, which is connected to the hydraulic cylinder 2.
