Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, and more specifically, to a mechanical parking equipment with a centering detection function. Background Technology

[0002] China's development is rapid, people's lives are improving significantly, and more and more people are buying cars. The contradiction between car ownership and the limited number of parking spaces in cities is becoming increasingly prominent, leading to parking difficulties and widespread illegal parking. Therefore, research on mechanical parking equipment that is small in size, inexpensive, reliable, and provides convenient and quick parking and retrieval is of great significance. Application number CN202222290928.0 describes a mechanical parking device with a centering detection function. It includes a garage frame installed on the ground, a lifting mechanism at the top of the frame, and a horizontally positioned upper car-carrying plate inside the frame, which is mounted on the frame via the lifting mechanism. A lower car-carrying plate, corresponding to the upper plate, is positioned directly below it and rests on the ground via a transverse track. The lower car-carrying plate is characterized by comprising several evenly spaced support plates, which serve as parking spaces for vehicles. The parking spaces are matched to the vehicles to be parked. Two vertically mounted sensor brackets are installed on the ground behind each row of support plates. These brackets are symmetrically positioned on either side of the centerline of the row of support plates, with the distance between them greater than the width of the vehicle but less than the width of the support plate. A photoelectric sensor is detachably fixed to the top of each sensor bracket. A retractable safety gate provides protection in front of the support plate, with reflectors corresponding to the photoelectric sensors fixed inside the gate. The garage frame is equipped with a human-machine interface, a PLC controller, and an audible and visual alarm. However, because the sensors are fixed to the ground via brackets, when parking, especially at excessive angles, the vehicle can easily collide with the sensors, causing damage and scratches, resulting in property loss and affecting the normal operation of the parking equipment.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example

[0018] Please refer to the accompanying drawings in the specification. In this embodiment of the utility model, a mechanical parking device with a centering detection function includes a parking device frame fixedly installed on the ground. The parking device frame includes a plurality of vertically fixed supporting columns 1. A plurality of sets of horizontal beams 2 and longitudinal beams 3 are fixedly connected in layers on the columns 1. A plurality of parking plates are provided between each layer of the horizontal beams 2 and longitudinal beams 3, and the parking plates are installed on the parking device frame through a lifting mechanism.

[0019] The parking equipment frame has two sets of first guide rails 4 fixedly installed longitudinally on the ground. The bottom parking plate 5 is rolled on the first guide rail 4. When the parking position is in place, the bottom parking plate 5 is located below the area between the two longitudinal beams 3 of the upper layer. CCD cameras 12 are fixedly installed in the middle of the bottom surface of the bottom longitudinal beams 3. The parking equipment frame is equipped with a human-machine interface, a PLC controller and an audible and visual alarm.

[0020] As a possible example, in this embodiment, in addition to the second guide rail 6 being fixedly installed on the topmost crossbeam 2, an intermediate parking plate 7 is installed between two adjacent longitudinal beams 3 on the same layer via rollers and a drive mechanism on the second guide rail 6, and a top parking plate 8 is installed on the topmost crossbeam 2. Both the intermediate parking plate 7 and the top parking plate 8 can be raised and lowered within the parking equipment frame via a lifting mechanism.

[0021] Specifically, in this embodiment, the lifting mechanism includes a lifting motor 9 and a rotating shaft 10. Sprockets are fixedly installed on the output shaft of the lifting motor 9 and the rotating shaft 10. The lifting motor 9 drives the rotating shaft 10 to rotate through the sprocket and chain drive. A wire rope drum 11 is provided on the rotating shaft 10. A wire rope is wound on the wire rope drum 11, and one end of the wire rope is connected to the intermediate parking plate 7 or the top parking plate 8. The number of intermediate parking plates 7 on each layer is equal to the number of bottom parking plates 5, and the number of top parking plates 8 is one less than the number of intermediate parking plates 7 on each layer.

[0022] As a possible example, in this embodiment, the CCD camera 12 is electrically connected to a human-machine interface (HMI). The HMI includes an image processing system, a processor, and an I / O interface. The HMI is connected to a PLC controller via the I / O interface. The PLC controller is electrically connected to the audible and visual alarm and the lifting mechanism. This invention utilizes machine vision to detect whether a vehicle is parked correctly. Specifically, the CCD camera 12 transmits images of both sides of the parking platform to the image processing system, converts them into digital signals, and performs various calculations on the digital signals to extract target features. The processor then calculates and determines whether the parked vehicle exceeds the maximum allowable range (e.g., ...). Figure 3 Within the area shown by the two dashed lines, if a vehicle exceeds the maximum parking area, the PLC controller will activate an audible and visual alarm to issue voice and light warnings. Machine vision is a relatively mature technology, and those skilled in the art can design and use it according to the application scenario.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
