Description

Technical Field

[0001] This utility model relates to the field of auxiliary facilities for multi-level parking garages, and in particular to a vehicle chassis detection device. Background Technology

[0002] In some intelligent automated parking garages, drivers park their cars at the entrance and exit, and then car-moving robots crawl under the car chassis from the front or rear to move the car to the parking space. Because different car models have different chassis heights, some cars have modified chassis armor, or there are foreign objects under the chassis, the robot may scratch the car when it enters. To avoid damage to the robot or the vehicle chassis, patent publication CN114136218B discloses a chassis detection device. This device detects the chassis height using a pair of fixed photoelectric sensors. However, if a plastic sheet-like obstruction is hung on the vehicle chassis, the device will determine that the vehicle chassis height exceeds the standard. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an automotive chassis testing device. By installing a spring between the base and the mounting seat, the pressure rod, mounting seat, and mounting plate are elastically installed relative to the base, thereby achieving contact-type testing of the automotive chassis without causing rigid wear to the chassis during the testing process.

[0004] The technical solution adopted by this utility model is as follows:

[0005] An automotive chassis testing device includes a base, a rotating seat, a mounting plate, a pressure rod, a spring, and a detection photoelectric component. The detection photoelectric component is disposed inside the base. There are at least two rotating seats, one end of which is rotatably engaged with the base. One end of the spring abuts against the base, and the other end of the spring abuts against the rotating seat. Each rotating seat is provided with a mounting plate. The two ends of the pressure rod are rotatably engaged with mounting holes on the two mounting plates, respectively.

[0006] In this type of automobile chassis testing device, the rotating seat can rotate relative to the base. An mounting plate is installed on the rotating seat, and a pressure rod is installed on the mounting plate. When an external object touches the pressure rod, it will push the rotating seat toward the base. When the external force is removed, the pressure rod and the rotating seat will return to their original positions before the movement began, thanks to the action of the spring.

[0007] The chassis inspection process of this device is as follows: First, the entire device is positioned between the vehicle's tires. When the vehicle drives over it, and the chassis presses against the pressure rod, mounting plate, or rotating base, the pressure rod will move towards the base. This movement is detected by the photoelectric detection component. When the pressure rod is detected by the photoelectric detection component, it is determined that the vehicle chassis is too low and unsuitable for transport by a handling device. Furthermore, in this inspection device, the rotating base, mounting plate, and pressure rod utilize springs for flexible installation, thus ensuring reliable inspection without causing rigid damage to the vehicle chassis.

[0008] In summary, this chassis testing device achieves elastic mounting of the pressure rod, mounting base, and mounting plate relative to the base by setting a spring between the base and the mounting seat, thereby enabling contact testing of the automobile chassis without causing rigid wear to the chassis during the testing process.

[0009] Optionally, a detection baffle is provided on the pressure rod.

[0010] The function of the detection baffle is to trigger the detection of the photoelectric component by blocking it.

[0011] Optionally, the detection photoelectric component includes a photoelectric emitting part and a photoelectric receiving part, the detection baffle is located between the photoelectric emitting part and the photoelectric receiving part, and the pressure rod is located between the photoelectric receiving part and the photoelectric emitting part.

[0012] When the pressure rod moves towards the bottom of the base, the detection baffle will block the photoelectric emitter and the photoelectric receiver.

[0013] Optionally, the mounting hole is an oval-shaped mounting hole, and a bolt is mounted on the pressure rod, with the mounting hole located between the end of the bolt and the pressure rod.

[0014] The bolts and the pressure rod together clamp the mounting plate, thereby installing the pressure rod onto the mounting plate. Since the mounting hole is oval-shaped, the installation height of the pressure rod relative to the mounting plate can be adjusted.

[0015] Optionally, the rotating seat is rotatably mounted on the base via a pin.

[0016] Optionally, the base is a flat-bottomed U-shaped base, and each side of the base is provided with a horizontal piece, the two horizontal pieces are not in contact, and the pressure rod is located between the two horizontal pieces.

[0017] The two horizontal plates can shield and protect the photoelectric emitting and receiving parts located on the base.

[0018] Optionally, the pressure rod is parallel to the base and does not contact the base.

[0019] Optionally, the pressure bar is a cylindrical pressure bar.

[0020] The beneficial effects of this utility model are: by setting a spring between the base and the mounting seat, the pressure rod, the mounting seat and the mounting plate are elastically installed relative to the base, thereby realizing contact testing of the car chassis, and will not cause rigid wear to the chassis during the testing process.

The detection photoelectric component is disposed inside the base 1. There are at least two rotating seats 2, one end of each rotating seat 2 is rotatably engaged with the base 1.

[0031] In this type of automobile chassis testing device, the rotating seat 2 can rotate relative to the base 1.

When the external force is removed, with the help of the spring 10, the pressure rod 4 and the rotating seat 2 (i.e. move upward) will return to the position before the start of movement.

[0032] The chassis inspection process of this device is as follows: First, the entire device is positioned between the vehicle's tires. When the vehicle drives over it, and the chassis presses against the pressure rod 4, mounting plate 8, or rotating seat 2, the pressure rod 4 will move towards the base 1. This movement of the pressure rod 4 towards the base 1 will be detected by the photoelectric detection component.

Furthermore, in this inspection device, the rotating seat 2, mounting plate 8, and pressure rod 4 all utilize springs 10, achieving elastic installation. This ensures the reliability of the inspection without causing rigid damage to the vehicle chassis.

[0039] Bolt 5 and pressure rod 4 together clamp the mounting plate 8, thereby installing pressure rod 4 onto the mounting plate 8. Since the mounting hole 801 is an oval-shaped mounting hole, the installation height of pressure rod 4 relative to the mounting plate 8 can be adjusted.
