Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, and in particular to a lifting chassis detection device. Background Technology

[0002] With the increasing demand for urban parking, horizontal moving parking equipment has been widely used due to its high space utilization and convenient operation. This equipment achieves high-density, three-dimensional parking of vehicles through intelligent mechanical structures, maximizing the use of limited land resources to increase parking capacity. The equipment utilizes the coordinated operation of lifting and transporting devices and lateral moving trolleys to arrange parking spaces vertically in layers and precisely dispatch vehicles horizontally through a central aisle. Drivers only need to park their vehicles on the fixed platforms at the entrance and exit; the system automatically completes the entire process of lifting, transferring, and parking the vehicle in the designated space, significantly optimizing urban space utilization. It is particularly suitable for land-constrained areas such as commercial centers and hospitals, quickly responding to parking needs, greatly reducing waiting time, and lowering manual management costs.

[0003] Currently, when using planar moving parking equipment, the detection of the chassis height after a vehicle enters the parking equipment is crucial for the safe operation of the equipment. Existing chassis detection devices are usually fixed, which not only occupies a certain amount of space, but also makes it easy for vehicles to run over and damage the chassis detection device, increasing subsequent maintenance costs. In addition, the overall structure of existing chassis detection devices is relatively complex and not convenient to operate, making it difficult to meet the safety and reliability requirements of modern parking equipment.

[0004] Therefore, it is necessary to provide a lifting chassis inspection device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a lifting chassis detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: a lifting chassis detection device, comprising a parking compartment base, a parking compartment platform pit formed inside the parking compartment base, a parking platform disposed within the parking compartment platform pit, chassis detection photoelectric switches for measuring vehicle chassis space disposed at both ends of the parking compartment platform pit, mounting seats fixed at both ends of the parking compartment platform pit, a servo motor fixed on the outer wall of the mounting seat, and a chain drive assembly for adjusting the lifting of the chassis detection photoelectric switches via the servo motor drive.

[0007] As a further embodiment of this utility model, the chain drive assembly includes a transmission guide rail fixed inside the mounting base. Two transmission guide rails are provided and are symmetrically distributed. A rigid chain is slidably connected inside the transmission guide rail. The mounting base is equipped with a driving sprocket and multiple driven sprockets that mesh with the rigid chain. Multiple meshing teeth are fixed on both rigid chains. When the two rigid chains are partially close to each other, the meshing teeth of the two rigid chains mesh with each other so that one end of the meshing tooth can be vertically raised and lowered. The chassis detection photoelectric switch is fixed at the vertically raised and lowered end of the two rigid chains.

[0008] As a further embodiment of this utility model, the output end of the servo motor is connected to a main drive shaft, and multiple slave drive shafts are rotatably connected to the mounting base. Both the main drive shaft and one of the slave drive shafts are fixed with drive gears, and the two drive gears are meshed together.

[0009] As a further embodiment of this invention, a coupling is provided between the output shaft of the servo motor and the main drive shaft.

[0010] As a further embodiment of this utility model, the mounting base is fixed to the side wall of the parking room platform pit by a plurality of expansion bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The chassis detection photoelectric switch is driven upward by a chain drive component. Once the switch reaches the set height, it detects the vehicle chassis height via photoelectric switches at both ends of the parking platform pit. This allows for chassis height detection after the vehicle has come to a complete stop, ensuring the chassis height meets parking and retrieval requirements and guaranteeing the safe operation of the parking equipment. When not in use, the chassis detection photoelectric switch can be lowered and stored in the parking platform pit, placing it below the parking platform. This reduces space occupation, prevents vehicles from running over the switch, and extends its service life. The chassis detection device of this invention has a simple overall structure, is easy to operate, and can quickly detect vehicle chassis height. It is suitable for various planar moving parking equipment and has broader application value. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-6This utility model provides a lifting chassis detection device, including a parking compartment base 9, a parking compartment platform pit 8 inside the parking compartment base 9, a parking platform 7 inside the parking compartment platform pit 8, and chassis detection photoelectric switches 5 for measuring the vehicle chassis space at both ends of the parking compartment platform pit 8. Mounting seats 2 are fixed at both ends of the parking compartment platform pit 8, and servo motors 4 are fixed on the outer walls of the mounting seats 2. The servo motors 4 are driven by a chain drive assembly 3 for adjusting the lifting of the chassis detection photoelectric switches 5. Specifically, the chassis detection photoelectric switch 5 can be a reflective photoelectric distance sensor specifically used for measuring the vehicle chassis height above the ground. It calculates the real-time distance between the lowest point of the chassis and the detection surface by emitting an infrared beam and receiving the reflected signal. Its specific structure and working principle have been fully disclosed in the prior art and will not be repeated in this application. In use, after the vehicle is parked on the parking platform 7, the servo motor... The machine 4 drives the chain drive assembly 3 to work, thereby driving the chassis detection photoelectric switch 5 to move upward through the chain drive assembly 3. When the chassis detection photoelectric switch 5 rises to the set height position, the chassis detection photoelectric switch 5 at both ends of the parking room platform pit 8 detects the vehicle chassis height, realizing the detection of the vehicle chassis height after the vehicle has come to a complete stop, ensuring that the vehicle chassis height meets the requirements for parking and retrieval, and ensuring the safe operation of the parking equipment. When the chassis detection photoelectric switch 5 is not in use, it can be lowered and stored in the parking room platform pit 8, that is, the chassis detection photoelectric switch 5 is placed under the parking platform 7, thereby reducing space occupation, preventing vehicles from running over the chassis detection photoelectric switch 5, and extending its service life. The chassis detection device of this utility model has a relatively simple overall structure, convenient detection operation, and can quickly detect the vehicle chassis height. It is suitable for various planar moving parking equipment and has a wide range of application value.

[0024] Further as Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, it is worth noting that the chain drive assembly 3 includes a transmission guide rail 301 fixed inside the mounting base 2. Two transmission guide rails 301 are provided and symmetrically distributed. A rigid chain 303 is slidably connected within the transmission guide rail 301. The mounting base 2 houses a drive sprocket 302 and multiple driven sprockets 305 that mesh with the rigid chain 303. Multiple meshing teeth 304 are fixed on both rigid chains 303. When the two rigid chains 303 are partially close together, the meshing teeth 304 engage to achieve the desired effect. One end of the meshing gear 304 can be vertically raised and lowered. The chassis detection photoelectric switch 5 is fixed at the vertically raised and lowered end of the two rigid chains 303. The output end of the servo motor 4 is connected to the main drive shaft 307. Multiple slave drive shafts 306 are rotatably connected to the mounting base 2. A transmission gear 308 is fixed on both the main drive shaft 307 and one of the slave drive shafts 306, and the two transmission gears 308 are meshed together. In actual operation, the output end of the servo motor 4 drives the main drive shaft 307 to rotate, and the main drive shaft 307 drives the transmission gear 308 and the drive sprocket 302 on it to rotate. The rotation, through the meshing of two transmission gears 308, drives the driven sprockets 306 and 305 on the driven sprockets 306 to rotate synchronously. This causes the two rigid chains 303 to rotate with the driving sprocket 302 and multiple driven sprockets 305, enabling synchronous movement of the two rigid chains 303. The movement of the rigid chains 303 is guided and limited by the transmission guide rail 301. In the vertical ejection direction, the rigid chains 303 mesh with each other through meshing teeth 304, ensuring vertical lifting and lowering during ejection. The chassis detection photoelectric switch 5 is located on both... The top of the rigid chain 303 allows the chassis detection photoelectric switch 5 to move vertically up and down. When the chassis detection photoelectric switch 5 is pushed out to the set height position, the chassis detection photoelectric switches 5 at both ends of the parking room platform pit 8 begin to detect the vehicle chassis height. By using rigid chain drive instead of traditional belt drive, the transmission accuracy and reliability are improved, adapting to frequent lifting and lowering needs. The overall structure is relatively simple, the detection operation is convenient, and it can quickly detect the vehicle chassis height. It is suitable for various planar moving parking equipment and has broad application value.

[0025] This solution has the following working process: After the vehicle stops on the parking platform 7, the output of the servo motor 4 drives the main drive shaft 307 to rotate. The main drive shaft 307 drives the transmission gear 308 and the drive sprocket 302 on it to rotate. The meshing of the two transmission gears 308 drives the driven drive shaft 306 and the driven sprocket 305 on the driven drive shaft 306 to rotate synchronously. As a result, the two rigid chains 303 rotate with the drive sprocket 302 and multiple driven sprockets 305, enabling the two rigid chains 303 to move synchronously. The rigid chain 303 is guided and limited by the transmission guide rail 301. In the vertical ejection direction, the rigid chain 303 meshes with each other through the meshing teeth 304 to ensure that the rigid chain 303 moves vertically up and down when ejecting. The chassis detection photoelectric switch 5 is set at the top of the two rigid chains 303, so that the chassis detection photoelectric switch 5 can be driven by the rigid chain 303 to move vertically up and down. When the chassis detection photoelectric switch 5 is ejected to the set height position, the chassis detection photoelectric switches 5 at both ends of the parking room platform pit 8 start to detect the vehicle chassis height.

[0026] Further as Figure 4 As shown, it is worth noting that a coupling 6 is connected between the output shaft of the servo motor 4 and the main drive shaft 307; the torque is rigidly transmitted through the coupling 6, and the output power of the servo motor 4 is transmitted to the main drive shaft 307 to ensure efficient power output.

[0027] Further as Figure 1 As shown, it is worth noting that the mounting base 2 is fixed to the side wall of the parking room platform pit 8 by multiple expansion bolts.

[0028] In summary: After the vehicle comes to a complete stop on the parking platform 7, the servo motor 4 drives the chain drive assembly 3, which in turn drives the chassis detection photoelectric switch 5 to move upwards. When the chassis detection photoelectric switch 5 rises to the set height, the vehicle chassis height is detected by the chassis detection photoelectric switches 5 at both ends of the parking platform pit 8. This allows for detection of the vehicle chassis height after the vehicle has come to a complete stop, ensuring that the vehicle chassis height meets the requirements for parking and retrieval, and ensuring the safe operation of the parking equipment. When the chassis detection photoelectric switch 5 is not in use, it can be lowered and stored in the parking platform pit 8, i.e., the chassis detection photoelectric switch 5 is placed under the parking platform 7, thereby reducing space occupation, preventing vehicles from running over the chassis detection photoelectric switch 5, and extending its service life. The chassis detection device of this utility model has a relatively simple overall structure, is convenient to operate, and can quickly detect the vehicle chassis height. It is suitable for various planar moving parking equipment and has broad application value.

[0029] The servo motor 4 can be purchased from the market. The servo motor 4 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
