Problems solved by technology

Although such a caster has a simple structure, its load-bearing capacity is insufficient. It can be retracted freely by manpower in the unloaded state, but when the load is too heavy, there will be jams or even jams between the shaft and the guide groove, resulting in the inability to slide , it is difficult to realize the retractable function

Embodiment 1

[0039] Such as Figure 1 to Figure 5 The electronically controlled cart shown includes a car body, a remote control panel, and casters located at the bottom of the car body. A power module and a controller electrically connected to the caster wheels are fixedly installed on the car body, and the remote control panel is wirelessly connected to the controller. The caster of this embodiment is an automatically retractable caster, including a fixed seat 1, a drive mechanism 2 fixedly installed in the fixed seat 1 and a transmission mechanism rotatably installed in the fixed seat 1, one end of the transmission mechanism and the output of the drive mechanism 2 The shafts are fixed and connected, and the other end is rotated with a wheel 3 with a hub motor. Use the remote control panel to control the movement of the caster, drive the transmission mechanism through the drive mechanism 2 to drive the wheel 3 to move down and reset, and use the hub motor to control the rotation and stop ...

Embodiment 2

[0051] The structure of this embodiment is similar to Embodiment 1, the difference is that the structure of the transmission mechanism is different, such as Figure 6 to Figure 7 As shown, Wheel 3 uses a three-inch brushless hub motor. The transmission mechanism includes a transmission assembly symmetrically arranged on both sides of the main body of the electric push rod. The transmission assembly includes a gas spring 23 and a second connecting rod 24 connected in rotation. The right end of the second connecting rod 24 is connected to the wheel 3 in rotation, and the middle part is connected to the fixed seat 1 The side wall rotation connection. Push the gas spring 23 through the electric push rod, and use the gas spring 23 to pull the second connecting rod 24 to rotate clockwise, thereby realizing the downward movement of the wheel 3. The structure is simpler, the production cost is low, and different usage requirements are met.

Abstract

The invention discloses a trundle capable of being automatically folded and unfolded and an electric control cart. The trundle capable of being automatically folded and unfolded comprises a fixed seat, a driving mechanism fixedly mounted in the fixed seat and a transmission mechanism rotatably mounted in the fixed seat. One end of the transmission mechanism is fixedly connected with an output shaft of the driving mechanism, the other end is rotationally provided with a wheel with a hub motor, and the driving mechanism is suitable for driving the transmission mechanism to act so as to drive the wheel to move downwards and reset. The wheel with a hub motor is arranged, so that rotation and stop of the wheel are controlled, the driving mechanism is arranged to drive the transmission mechanism to act, then automatic folding and unfolding of the wheel are achieved, the structure is simple, manual folding and unfolding of the wheel are not needed, the bearing capacity is excellent, and jamming is not likely to happen.

Description

technical field [0001] The invention relates to the technical field of intelligent machinery, in particular to an automatically retractable caster and an electronically controlled trolley. Background technique [0002] The so-called casters refer to the wheels that are connected to the lower part of the transportation device and can freely change the direction. They can be roughly divided into fixed casters and swivel casters. As an important part of many transporting appliances, casters are not only walking parts, but also undertake the function of shock absorption. [0003] During the actual use of the transport device, when it is moved to a designated position, it needs to be stable, safe and reliable, and then loaded / unloaded. In the prior art, there are certain disadvantages in the way of fixing the casters by adding a brake mechanism. The fixation requires additional parts. The brakes of the casters with brakes are easy to be loosened, and the wheels of the casters ar...
