Description

Technical Field

[0001] The present invention relates to the technical field of parking lot equipment, and particularly to a guiding robot for a parking lot with projective imaging function. Background Art

[0002] A parking lot refers to an area that provides temporary or long-term parking services for vehicles, and is usually composed of parking spaces, passages, entrances and exits, and necessary management facilities. The purpose of a parking lot is to solve the problem of vehicle parking, reduce illegal parking on the road, and thus improve the efficiency and safety of urban traffic.

[0003] Before a vehicle enters the parking lot for parking, it is unable to determine where there are vacant parking spaces inside the parking lot. After the vehicle enters the parking lot, it still needs to search for a parking space by itself. Blind searching may cause vehicle scratches, posing certain potential safety hazards.

[0004] In order to overcome the above defects, Prior Art 1 (a Chinese patent with the publication number: CN202120841988.X and the publication date of April 23, 2021) discloses an automatic guiding robot for an underground parking lot, which includes: a guiding machine bottom rod, which adopts a cylindrical hollow design and is sleeved with a cylindrical guiding top rod at the top; a machine bearing column, which is installed on the upper right of the guiding top rod and adopts a columnar structure design; a guiding plate, which is installed on the side wall of the machine bearing column, adopts a square design, and the surface of the guiding plate is covered with transparent glass; and a parking space guiding lamp, which is installed on the surface of the guiding plate. This automatic guiding robot for an underground parking lot can be installed at each corner point in the parking lot, and can assist drivers in finding parking spaces through information guidance and voice guidance, greatly reducing the complexity of parking, reducing traffic congestion, and reducing potential safety hazards. It is placed in a suspended manner, does not affect the normal driving of vehicles, does not occupy a large space, and uses LED lights for guidance, facilitating drivers to distinguish the direction of parking spaces.

[0005] There is also Prior Art 2 (a Chinese patent with the publication number CN212647690U and the publication date of March 2, 2021), a parking lot direction guiding device, which includes a fixed upper plate, a fixed connecting rod, a protective cover body, and a rotating guiding mechanism. The fixed connecting rod is arranged at the lower part of the fixed upper plate, the protective cover body is arranged on the fixed connecting rod, and the rotating guiding mechanism is arranged below the protective cover body. The rotating guiding mechanism includes a rotating motor, a rotating shaft, an indicating frame, a passage guiding frame, a controller, and a camera. The protective cover body is arranged as a hollow cavity with an open lower end. The rotating motor is arranged on the inner upper wall of the protective cover body. One end of the rotating shaft is arranged at the output end of the rotating motor. The passage guiding frame is arranged at the other end of the rotating shaft. The controller is arranged on the protective cover body. The indicating frame is arranged in a cross shape. A parking lot direction guiding device that is easy to install, can fully display parking lot information for direction guiding, can achieve safe and accurate direction guidance, ensure the parking order in the parking lot, and is efficient and practical.

[0006] Although Prior Art 1 and Prior Art 2 can guide the parking of vehicles, most of their guiding devices are in a fixed state and guide through voice broadcasting. Their guiding instructions are limited, and some car owners still cannot find their positions when parking.

[0007] Therefore, we propose a guiding robot for a parking lot with projective imaging to solve the problems raised above. Summary of the Invention

A buffer spring is fixedly connected between the edge of the buffer block and the buffer groove. The upper end of the buffer block is hinged with a buffer rotating rod, and the upper end of the buffer rotating rod is hinged on the side of the lower surface of the buffer placing plate.

[0013] Preferably, the buffer rotating rod forms a rotating structure with the buffer placing plate and the buffer block, the buffer block forms a sliding structure with the buffer groove through the buffer rotating rod, and the buffer block forms an elastic structure with the buffer groove through the buffer spring.

[0014] Preferably, a threaded rod is fixedly connected to the center of the lower surface of the buffer placing plate. A threaded sleeve rod is threadedly connected to the outside of the threaded rod. The threaded sleeve rod is nested and connected to the upper surface of the component box.

[0015] Preferably, the threaded sleeve rod forms a rotating structure with the component box through the threaded rod, and the turntable forms a rotating structure through the threaded sleeve rod.

[0016] Preferably, the adjusting rotating rod forms a rotating structure with the moving block through the turntable, the moving block forms a sliding structure with the moving groove through the adjusting rotating rod, and the inner side of the flexible pad is attached to the outside of the control box.

[0017] Preferably, the dust cleaning mechanism includes an airbag, which is fixedly connected to the rear side of the component box.

[0019] Preferably, the side of the zigzag plate is in contact with the side of the roller. The protruding end of the zigzag plate corresponds to the position of the airbag. The sliding block forms a sliding structure with the sliding groove through the reset spring.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) A signal receiving module and a data processing module are arranged inside the component box. The signal receiving module receives the signal of the available parking spaces in the parking lot, and the signal is received and sorted by the data processing module to plan the route. The planned route is transmitted to the control box, and the drive wheel driving device is used to move the vehicle. The three projection lamps arranged at the rear side of the control box project the indicator onto the ground, so that the vehicle owner can view the route and quickly find the available parking spaces.

[0022] (2) When the driving wheel group drives the device to move, the device will shake to a certain extent. At this time, the control box will drive the stabilizing mechanism to move under the influence of its own gravity, thereby improving the stability of the control box through the stabilizing mechanism and reducing the vibration force on the control box when moving;

[0023] (3) The control box, driven by its own gravity, will synchronously drive the buffer placement plate to move downward. At this time, the buffer placement plate will squeeze the buffer rotating rod, causing the buffer rotating rod to rotate. During the rotation of the buffer rotating rod, the buffer block will synchronously drive the buffer block to move within the buffer groove, and the buffer spring will be squeezed by the buffer block, causing the buffer spring to undergo elastic deformation. Driven by the elastic force of the buffer spring, the vibration generated when the device moves can be buffered, thereby reducing the impact force on the control box.

[0024] (4) When the buffer placement plate moves downward, it will synchronously drive the threaded rod to move inside the threaded sleeve rod. The threaded sleeve rod rotates under the threaded connection of the threaded rod and synchronously drives the turntable to rotate. When the turntable rotates, it will synchronously drive the adjustment rod to rotate, thereby pulling the stabilizing plate to move toward each other through the moving block. At this time, the stabilizing plate can drive the flexible pad to fit more closely with the side of the control box, further improving the stability of the control box placement;

[0025] (5) When the driving wheel group is rotating, it will synchronously drive the screw to rotate through the belt transmission structure. At this time, the adjustment block will slide along the component box under the driving action of the screw. When the adjustment block slides, it will synchronously drive the fixed seat to move. At this time, the roller set on the inner side of the fixed seat will roll along the side of the zigzag plate. Under the resistance of the zigzag plate, the roller will push the extrusion block outward, so that the extrusion block squeezes the airbag. The gas inside the airbag is discharged through the exhaust port set at the top, and the outside of the projection lamp is cleaned to reduce the interference of dust on the projection effect. At the same time, when the zigzag plate does not resist the roller, the roller will drive the extrusion block to move and reset under the drive of the elastic force of the reset spring. The roller is always in contact with the outside of the zigzag plate, which is convenient for cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
