Description

Technical Field

[0001] The present invention relates to the technical field of parking equipment, and in particular to an automobile extra-width detection system and method, and a three-dimensional parking garage. Background Art

[0002] The problem of having nowhere to park vehicles is the result of the social, economic and traffic development of the city to a certain extent, which seriously affects people's convenience and happiness in life, and poses a huge challenge to the orderly and safe management of the city. The advent of three-dimensional parking equipment has solved the problem of parking difficulties.

[0003] Mechanical three-dimensional parking equipment is a type that is currently widely used. When working, the lifting and transferring mechanism carries the vehicle from the parking entrance to the parking space to realize the parking operation, or transfers the vehicle from the parking space to the parking exit to realize the vehicle pickup operation. However, the side profile of the car is usually irregular, and the body color is also colorful according to different user needs. The reflectivity of different car paints varies. Therefore, a single-point photoelectric switch is used for detection. One line of light cannot effectively detect the protruding points on the entire side of the car body; or laser radar is used to detect the width of the car body. When the mirror surface of the rearview mirror is easily facing the scanning light of the laser radar, it will cause misjudgment and affect the accuracy of the detection of the vehicle body's excessive width.

[0066] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0067] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0068] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0069] Please refer to Figure 1-Figure 2 , is an embodiment of an automobile over-width detection system, which includes an entry and exit hall 10, the entry and exit hall 10 has at least two pairs of first vehicle body over-width detection switches 20 arranged at a relative interval in the horizontal direction, and the at least two pairs of first vehicle body over-width detection switches 20 are used to perform static primary over-width detection on the parked vehicle; a transfer channel 30, the transfer channel 30 is constructed in the vertical direction and runs through the entry and exit hall 10; a lifting and transferring mechanism 40, the lifting and transferring mechanism 40 is arranged in the transfer channel 30 in a lifting and movable manner, and the lifting and transferring mechanism 40 has At least two pairs of rearview mirror extra-width detection switches are arranged, and the at least two pairs of rearview mirror extra-width detection switches are used to perform dynamic rearview mirror extra-width detection and dynamic primary extra-width detection on the vehicle to be parked on the lifting and transferring mechanism 40; and a plurality of parking spaces 50, and the plurality of parking spaces 50 are stacked in a vertical direction above and / or below the entrance and exit hall 10, and the parking spaces 50 are provided with at least two pairs of second vehicle body extra-width detection switches arranged relatively spaced apart in a horizontal direction, and the at least two pairs of second vehicle body extra-width detection switches are used to perform dynamic secondary extra-width detection on the vehicle to be parked parked in the parking spaces 50.

[0070] It is easy to understand that the first vehicle body over-width detection switch 20 and the second vehicle body over-width detection switch are both used to measure the vehicle body width, in order to prevent the width of some vehicles from exceeding the width of the entrance and exit hall 10 and the width of the parking space 50, resulting in scratches on the vehicle when the vehicle enters and exits, causing property losses to the user. Optionally, the first vehicle body over-width detection switch 20 and the second vehicle body over-width detection switch can be a photoelectric switch or the like.

[0071] The rearview mirror over-width detection switch is used to measure the width of the vehicle (usually larger than the width of the vehicle body) constructed by the left and right rearview mirrors (expanded or folded) to prevent the risk of scratches due to the rearview mirror being too wide.

[0072] Figure 2 The two dotted lines drawn obliquely from the upper left to the lower right represent the right extra-wide detection and the left extra-wide detection of the vehicle body respectively; the two dotted lines drawn obliquely from the top to the lower left represent the right rearview mirror extra-wide detection and the left rearview mirror extra-wide detection respectively.

[0073] The lifting and transferring mechanism 40 of the present application is specifically a lifting platform, which is composed of a platform body and a lifting power mechanism. The lifting power mechanism outputs a lifting driving force to the platform body, so that the platform body can move up or down in the transfer channel 30 to transfer the vehicle to the target parking space 50.

[0074] For example, the transfer passage 30 is defined by the main frame of the three-dimensional parking garage and is a through space formed in the vertical direction. The structure and function of the elevator shaft can be specifically understood. A plurality of parking spaces 50 are vertically stacked at different height levels of the transfer passage 30, and each parking space 50 is generally used to park one vehicle.

[0075] Each parking space 50 is equipped with a sensor or a visual camera for monitoring whether there is a vehicle parked in the parking space 50. A parking space 50 without a parked vehicle will be recorded as a target parking space 50 by the control system, and a target parking space 50 closest to the vehicle to be parked in the entrance and exit hall 10 will be assigned for the parking operation.

[0076] Implementing the embodiments of the present invention will have the following beneficial effects: in the automobile extra-width detection system of the present scheme, by installing at least two pairs of first vehicle body extra-width detection switches 20 in the entrance and exit hall 10, installing at least two pairs of rearview mirror extra-width detection switches in the lifting and transferring mechanism 40, and installing at least two pairs of second vehicle body extra-width detection switches in each parking space 50, each detection switch can respectively detect the vehicle body width and rearview mirror width of the vehicle to be parked under different ambient light conditions and from different directions when the vehicle enters the entrance and exit hall 10, enters the lifting and transferring mechanism 40 and follows the lifting and transferring mechanism 40 to transfer to the target parking space 50, and transfers from the lifting and transferring mechanism 40 to the parking space 50, so as to effectively eliminate the influencing factors such as the irregular shape of the vehicle body contour, the reflection of the paint, the reflection of the rearview mirror, etc., improve the accuracy of the detection of the extra-width of the vehicle body (that is, the width of the vehicle body exceeds the maximum width value that can be accommodated by the entrance and exit hall 10, the lifting and transferring mechanism 40 and the parking space 50), and ensure the safety of the parking operation.

[0077] In one embodiment, at least two pairs of first vehicle body extra-width detection switches 20 are arranged on the first side of the width direction of the vehicle to be parked, and are used to detect the shape of the first side of the vehicle to be parked, and the detection light of at least two pairs of first vehicle body extra-width detection switches 20 extends from the front to the rear of the vehicle to be parked, and is set at an angle to the line connecting the front to the rear. In addition, at least two pairs of first vehicle body extra-width detection switches 20 are arranged on the second side of the width direction of the vehicle to be parked, and are used to detect the shape of the second side of the vehicle to be parked, and the detection light of at least two pairs of first vehicle body extra-width detection switches 20 extends from the front to the rear of the vehicle to be parked, and is set at an angle to the line connecting the front to the rear. In this way, it is conducive to more completely detecting the shape of the side of the vehicle body, adapting to irregular vehicle side shapes, and improving the accuracy of vehicle width detection.

[0078] In one embodiment, the vehicle over-width detection system further includes a lifting power mechanism, which is disposed at the top or bottom of the transfer channel 30 and is connected to the lifting and transferring mechanism 40 by transmission. For example, the lifting power mechanism can be a power device such as a winch, which is selectively installed at the top or bottom of the transfer channel 30 to avoid interference with the lifting and transferring mechanism 40 moving in the transfer channel 30. The wire rope of the winch is connected to the lifting and transferring mechanism 40 through a connector. When the wire rope is wound up by the winch, the length of the wire rope suspended in the vertical direction in the transfer channel 30 becomes shorter, and the lifting and transferring mechanism 40 moves upward; on the contrary, when the wire rope is wound up by the winch, the length of the wire rope suspended in the vertical direction in the transfer channel 30 becomes longer, and the lifting and transferring mechanism 40 moves downward.

[0079] Furthermore, in yet another embodiment, the outer peripheral wall of the lifting and transferring mechanism 40 is provided with a plurality of buffer mechanisms arranged at intervals, and a guide roller is provided at the end of the buffer mechanism, and the guide roller is used to roll in contact with the side wall of the transfer channel 30. When the vehicle travels from the outside to the lifting and transferring mechanism 40, it will inevitably cause an impact on the lifting and transferring mechanism 40, causing the lifting and transferring mechanism 40 to shake in the transfer channel 30. At this time, the guide roller rolls and collides with the side wall of the transfer channel 30, and the buffer mechanism offsets the collision impact, thereby preventing the lifting and transferring mechanism 40 from being damaged by the impact. In addition, when the lifting and transferring mechanism 40 is lifted and operated in the transfer channel 30, the guide roller rolls in contact with the side wall of the transfer channel 30, which can guide and stabilize the posture of the lifting and transferring mechanism 40, ensuring that the vehicle is parked firmly on the lifting and transferring mechanism 40 and is not prone to displacement or even falling.

[0080] Optionally, the buffer mechanism may be a mechanical spring, a gas spring, or the like.

[0081] In addition, in order to facilitate the flexible flow of vehicles between the lifting and transferring mechanism 40 and the parking space 50, a movable carrier is provided on the bottom wall of each parking space 50, which is used to transport the vehicle to be parked from the lifting and transferring mechanism 40 to the parking space 50, or to transport the vehicle to be parked from the parking space 50 to the lifting and transferring mechanism 40.

[0082] For example, the carrier includes a base, a motor, a gear, a rack, a movable carrier plate and a push block. The base is fixedly installed in a preset installation groove of the parking space 50. The motor is installed on the base and connected to the gear. The rack meshes with the gear. The rack moves back and forth between the parking space 50 and the lifting and transferring mechanism 40 under the transmission of the gear. The movable carrier plate is fixedly connected to the rack. The connection method can be one of screw connection, clamping connection, riveting, etc. The movable carrier plate is used to carry the vehicle. The push block is fixed on the upper surface of the movable carrier plate. The push block is used to move the vehicle to push the vehicle from the parking space 50 to the lifting and transferring mechanism 40, or pull the vehicle back from the lifting and transferring mechanism 40 to the parking space 50. The carrier has a simple structure and working principle, strong carrying capacity, and can effectively and reliably transport vehicles.
