Description

Technical Field

[0001] The utility model belongs to the technical field of stereo garages, and in particular relates to an ultra-low vehicle detection device for stereo garages. Background Art

[0002] During the process of storing and retrieving vehicles in the three-dimensional parking equipment, the vehicles need to be moved. For example, the clamp-wheel carrier needs to be moved to the bottom of the vehicle. After it is in place, the clamp arms are folded and the vehicle is lifted up for transportation. Therefore, for some vehicles with low chassis, it is difficult for the carrier to enter under the vehicle, or it may scratch the bottom of the vehicle and damage the vehicle or the carrier. Therefore, ultra-low detection should be carried out before the vehicle enters the garage for transportation to avoid the above situation.

[0003] The existing ultra-low detection equipment adopts a collision structure, and a baffle with a limited height is set on the ground at the vehicle entrance and exit. When the vehicle chassis is lower than the height of the baffle, the vehicle cannot enter the three-dimensional parking garage. This structure has two disadvantages. First, the vehicle will still contact and collide with the baffle, damaging the baffle or the vehicle. Second, the structure is complex, and the baffle is often damaged by collision. The baffle needs to be replaced continuously, which has high cost of use.

[0004] The applicant has also applied for an ultra-low vehicle detection device for a three-dimensional parking garage, comprising a vehicle carrier frame, on which a mounting frame driven by a power mechanism is vertically slidably installed, and on which a non-contact sensor for detecting the lowest position of the bottom of the vehicle is installed. The use of the non-contact sensor can accurately detect the lowest position of the bottom of the vehicle without contacting or colliding with the vehicle, thereby avoiding damage to the non-contact sensor, extending the service life of the non-contact sensor, and thereby reducing the cost of use.

[0005] However, the existing technologies all perform ultra-low detection on the vehicle when entering the vehicle. Sometimes when the vehicle is parked in the garage, the tire will leak air. Insufficient tire pressure will cause the vehicle chassis to lower, making it difficult for the transporter to enter the bottom of the vehicle when picking up the vehicle, or the bottom of the vehicle will be scratched, damaging the vehicle or the transporter.

[0006] Therefore, in the field of stereo garage technology, there is still a need for research and improvement on the ultra-low detection device for stereo garage vehicles. This is also a research hotspot and focus in the current field of stereo garage technology, and it is also the starting point for the completion of the present utility model. Utility Model Content

[0007] To this end, the technical problem to be solved by the utility model is: to provide a vehicle ultra-low detection device for a three-dimensional garage to solve the technical problem that when picking up a vehicle, the chassis is lowered due to insufficient tire pressure, making it difficult for a transporter to enter under the vehicle, thereby damaging the vehicle or the transporter.

[0008] In order to solve the above technical problems, the technical solution of the utility model is: a vehicle ultra-low detection device for a three-dimensional parking garage, comprising two first photoelectric detection elements installed on a carrier, the detection light column of the first photoelectric detection element having a detection range, the detection light columns of the two first photoelectric detection elements are cross-arranged to form a detection surface, and the two first photoelectric detection elements are both connected to a control unit.

[0009] As an improvement, it also includes a second photoelectric detection element fixedly installed at the vehicle entrance position for detecting the height of the bottom of the vehicle front, and the second photoelectric detection element is connected to the control unit.

[0010] As a further improvement, the second photoelectric detection element is arranged on one side of the vehicle's driving direction, the detection light column of the second photoelectric detection element has a detection range, and the detection light column of the second photoelectric detection element is provided with an angle with the vehicle's driving direction.

[0011] As a further improvement, the first photoelectric detection element and the second photoelectric detection element are both laser ranging switches.

[0012] After adopting the above technical solution, the beneficial effects of the utility model are:

[0013] (1) In the embodiment of the utility model, a first photoelectric detection element is provided on the carrier, and a dynamic detection surface is formed as the carrier moves. The detection area is large, and the chassis of the vehicle can be detected when the vehicle is picked up. If the lower limit is exceeded, a prompt is given not to pick up the vehicle, thereby avoiding the technical defect that the chassis is lowered due to tire leakage and insufficient tire pressure during the storage process, making it difficult for the carrier to enter the bottom of the vehicle, thereby damaging the vehicle or the carrier.

[0014] (2) Since a second photoelectric detection element is provided at the vehicle entrance, detection begins when the vehicle enters the detection range. As the vehicle moves forward, the detection light beam of the second photoelectric detection element forms a scanning plane to detect the bottom of the front of the vehicle. This relatively dynamic detection plane has a large detection range and is more accurate and reliable. It makes a judgment before the vehicle enters the garage, reducing subsequent processes.

People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1:

[0024] like Figure 1 and Figure 2As shown, the utility model provides an ultra-low vehicle detection device for a stereo garage, comprising two first photoelectric detection elements 2 installed on a carrier 1, the first photoelectric detection element 2 is usually a laser ranging switch, the detection light column 3 of the first photoelectric detection element 2 has a detection range, and the detection range is usually 0-5 meters. It is sufficient to detect an ordinary vehicle chassis within this detection range. The detection light columns 3 of the two first photoelectric detection elements 2 are cross-arranged to form a detection surface. As the carrier 1 moves forward, the detection surface also gradually moves forward to form a detection of the entire surface of the vehicle chassis. Compared with traditional line detection, the detection area is large and the detection is more comprehensive. The two first photoelectric detection elements 2 are connected to a control unit, and the control unit is preferably a PLC programmable controller.

[0025] The utility model provides a first photoelectric detection element 2 on the carrier 1, and forms a dynamic detection surface with the movement of the carrier 1. The detection area is large, and the chassis of the vehicle can be detected when the vehicle is picked up. If the lower limit is exceeded, a prompt is given not to pick up the vehicle, thereby avoiding the technical defect that the carrier 1 is difficult to enter the bottom of the vehicle due to tire leakage and insufficient tire pressure during the storage process, resulting in the lowering of the chassis, which damages the vehicle or the carrier 1.

[0026] Embodiment 2:

[0027] The utility model provides a vehicle ultra-low detection device for a stereo garage, which is further improved on the basis of the first embodiment. Figure 3 As shown, it also includes a second photoelectric detection element 4 fixedly installed at the vehicle entrance position for detecting the height of the bottom of the vehicle front. Because the vehicle front position is provided with power components such as an engine, which are relatively heavy, therefore, if the chassis of the front of the vehicle does not exceed the lower limit, it is judged that the chassis of the entire vehicle does not exceed the lower limit, and the vehicle is allowed to enter the garage. The second photoelectric detection elements 4 are all laser ranging switches, and the second photoelectric detection elements 4 are connected to the control unit. The second photoelectric detection element 4 is arranged on one side of the vehicle's driving direction. The detection light column 5 of the second photoelectric detection element 4 has a detection range, which is usually 0-5 meters, which can meet the use requirements of ordinary vehicles. The detection light column 5 of the second photoelectric detection element 4 is arranged at an angle with the vehicle's driving direction, and the angle is usually an acute angle, so that the detection light column 5 of the second photoelectric detection element 4 can extend as much as possible into the bottom of the vehicle.

[0028] When in use, the second photoelectric detection element 4 is fixed on the mounting frame on the side of the vehicle's driving direction. When the vehicle enters the detection range, detection begins. As the vehicle moves forward, the detection light column 5 of the second photoelectric detection element 4 forms a scanning surface to detect the bottom of the front of the vehicle. This relatively dynamic detection plane has a large detection range and is more accurate and reliable. When the front wheel of the vehicle close to the side of the second photoelectric detection element 4 approaches the detection light column 5 of the second photoelectric detection element 4, the detection ends. If it is found that the vehicle chassis exceeds the lower limit, an alarm is triggered and the vehicle is not allowed to enter the garage. A judgment is made before the vehicle enters the garage, which reduces subsequent processes.

[0029] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
