Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission equipment, and more specifically, it relates to a universal moving drive wheel mechanism. Background Technology

[0002] Casters, also known as swivel casters, are designed to rotate 360 ​​degrees horizontally. "Caser" is a general term encompassing both swivel and fixed casters. Fixed casters lack a rotating mechanism and can only rotate vertically, not horizontally.

[0003] Currently, most casters have a relatively simple structural design. Although they can assist the device in moving freely when installed at the bottom, the steering of the wheels is basically passive and it is not convenient to achieve active steering. This makes it inconvenient for the platform mounted on them to actively adjust the direction of movement. In logistics transportation scenarios, they can only be manually pushed to steer, which is inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a universal moving drive wheel mechanism that can move autonomously in multiple directions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A universal moving drive wheel mechanism is provided, comprising a mounting shaft and a support plate. Rollers are fixedly connected to both the front and rear ends of the mounting shaft. An electric cylinder and a telescopic rod are rotatably connected to the outer wall of the mounting shaft. The output ends of the electric cylinder and the telescopic rod are fixedly connected to the mounting plate. A fixed shaft is fixedly connected to the mounting plate. A steering gear is fixedly connected to the outer wall of the fixed shaft. A lifting plate is fixedly connected to one side of the lower end face of the support plate. A steering motor is fixedly connected to the lifting plate. A drive gear is fixedly connected to the output end of the steering motor, and the drive gear meshes with the steering gear. A first reinforcing plate is fixedly connected to the outer wall of the electric cylinder and the telescopic rod. A drive motor is fixedly connected to the first reinforcing plate. A first transmission wheel is fixedly connected to the output end of the drive motor. A second transmission wheel is fixedly connected to the outer wall of the mounting shaft. A transmission belt is sleeved on the outer walls of the first and second transmission wheels.

[0006] Optionally, a second reinforcing plate is fixedly connected to the outer wall of the electric cylinder and telescopic rod on the side away from the first reinforcing plate. An electric rod is rotatably connected to the front end of the second reinforcing plate. A limit frame is fixedly connected to the output end of the electric rod. A tension wheel is rotatably connected to the limit frame. The transmission belt passes between the tension wheel and the limit frame.

[0007] Optionally, the electric cylinder and the telescopic rod are disposed between the two rollers, and the transmission wheel is disposed between the electric cylinder and the roller located at the front end.

[0008] Optionally, the horizontal height of the lower end face of the lifting plate is greater than the horizontal height of the upper end face of the roller, and the minimum distance between the lifting plate and the first reinforcing plate is greater than 1 cm.

[0009] Optionally, a connecting plate is fixedly connected between the electric cylinder and the telescopic rod, and a battery is fixedly installed at the upper end of the connecting plate.

[0010] Optionally, an auxiliary rotating ring is fixedly connected to the upper end of the steering gear, and the auxiliary rotating ring is rotatably connected inside the support plate. Beneficial effects

[0011] 1. This universal moving drive wheel mechanism, compared with the prior art, by setting up a steering gear, an auxiliary rotating ring, a support plate, a mounting plate, a steering motor, and a drive gear structure to cooperate with each other, can use the steering motor to drive the drive gear to rotate, thereby driving the steering gear to rotate relative to the support plate, thereby driving the mechanism fixedly installed below the steering gear to rotate, ultimately achieving the effect of adjusting the active rotation of the roller. At the same time, with the help of the transmission belt to drive the first transmission wheel and the second transmission wheel to rotate simultaneously, the drive motor can drive the mounting shaft to rotate, thereby driving the roller to rotate actively, thus enabling the support platform mounted on the support plate to move freely, which is especially suitable for use in cargo transportation scenarios.

[0012] 2. Compared with the prior art, this universal moving drive wheel mechanism, by setting up an electric cylinder, telescopic rod, mounting plate and fixed shaft structure, can stably drive the mounting plate to rise and fall under the limit of the telescopic rod by the action of the electric cylinder, and finally realize the control of the rise and fall of the support plate, thereby facilitating the height adjustment of the platform mounted on the support plate and improving practicality.

[0013] 3. Compared with the prior art, this universal moving drive wheel mechanism, by setting up a reinforcing plate, an electric rod, a limit frame and a tension wheel structure, can drive the limit frame to move under the action of the electric rod, thereby driving the tension wheel to move and adjust the tension of the transmission belt, thus improving the stability of the transmission belt during transmission.
