Fig. 1 shows a schematic structural diagram of a retractable support arm according to an embodiment of the present invention. Fig. 2 shows a schematic structural diagram of a retractable support arm according to an embodiment of the present invention. As shown in the drawings, a retractable support arm 100 suitable for a parking robot 200 mainly includes a fixed guide arm 101, a movable arm 102, and a driving mechanism.

The retractable support arm 100 is horizontally disposed at the bottom of the parking robot 200.

The fixed guide arm 101 and the drive mechanism are provided on the parking robot 200.

The movable arm 102 is movably engaged with the fixed guide arm 101, the driving mechanism drives the movable arm 102 to move in the longitudinal direction of the fixed guide arm 101, and a universal wheel 103 is provided at the bottom of the front end of the movable arm 102.

It is easy to understand that the parking robot 200 has steering wheels, and after the movable arms 102 extend outwards, the combination of the steering wheels and the universal wheels 103 on the telescopic arms forms a support area far larger than the steering wheel support area of the parking robot 200 when it is unloaded, so as to obtain better support stability.

Preferably, the moving direction of the movable arm 102 is perpendicular to the longitudinal direction of the parking robot 200.

Preferably, the drive mechanism is a hydraulic pump 104. The telescoping support arm 100 is moved by a hydraulic pump 104 to actuate a moveable arm 102. By way of example and not limitation, the drive mechanism may alternatively be a nut screw. The telescopic support arm 100 drives the movable arm 102 to extend outwards through a nut screw.

Preferably, the retractable support arm 100 further comprises a sensing switch 105 and a sensing piece 106, the sensing switch 105 is disposed on the fixed guide arm 101, the sensing piece 106 is disposed on the movable arm 102, and the sensing switch 105 and the sensing piece 106 are electrically connected. In this embodiment, when the retractable supporting arm 100 needs to be opened, the sensing switch 105 is activated, the sensing piece 106 works, and when the sensing piece 106 senses the limit range of the sensing switch 105, which indicates that the movable arm 102 has extended to the limit distance, the feedback is sent to the controller on the parking robot 200, and the controller instructs the driving mechanism to stop, so as to ensure that the movable arm 102 does not disengage from the fixed guiding arm 101.

The utility model also provides a parking robot 200, including two sets of foretell retractable support arms 100 at least. The parking robot 200 can open the retractable support arm 100 before lifting the tire of the vehicle, so as to increase the overall support area, so that the parking robot 200 has a stable center of gravity when loading the vehicle, the load distribution is reasonable, and enough adhesive force and driving force are generated to improve the safety. When the parking robot 200 travels in an unloaded state, the movable arm 102 is retracted to reduce the occupied space, so that the size of the structure is reduced as much as possible in order to smoothly travel between the spaces of the vehicles.

Preferably, the two sets of telescoping support arms 100 are arranged in parallel.

Preferably, the two sets of telescoping support arms 100 work synchronously with the extension direction of the movable arms 102 being the same. In other words, the movable arms 102 of the two sets of the retractable support arms 100 extend toward one side of the lifted wheel, so that the occupied space of the outer side can be reduced, and the parking safety can be improved.

It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
