[0013] The beneficial effects of the present invention are as follows: 1.

Since the propagation speed of ultrasonic waves on common garbage such as fallen leaves and packaging bags attached to the vehicle chassis is significantly different from that on the vehicle chassis, the garbage on the vehicle chassis will not have a significant impact on the measurement results.

When the position adjustment of the ultrasonic detector is completed, the vacuum cleaner stops vacuuming to avoid affecting the measurement of the ultrasonic detector; 6. The present invention provides a replacement door and an inspection door, so that when the vacuum cleaner works for a long time or the components inside the dust collection tank are damaged, the maintenance personnel can open the inspection door from the outside to inspect the components inside the dust collection tank, and can open the vacuum cleaner storage and replacement door to clean and replace the dust bag inside the vacuum cleaner to maintain the dust collection performance of the vacuum cleaner; 7. The present invention provides a dust blowing fan, so that when the camera detects that the vehicle is about to drive onto the concrete frame, the dust blowing fan in the dust blowing slot can be controlled to start, and the dust blowing fan blows strong wind to the outside through the dust blowing wide mouth plate, the first dust blowing hole and the second dust blowing hole on the speed bump.

[0019] like Figures 1 to 11As shown, a vehicle chassis height detection device for a three-dimensional garage includes a garage foundation 1, such as Figure 1 As shown, a concrete frame 2 is buried inside the garage foundation 1, and the upper surface of the concrete frame 2 is flush with the upper surface of the garage foundation 1. Figure 2 As shown, three horizontally arranged detection grooves 201 are provided on the top of the concrete frame 2. The three detection grooves 201 are parallel to each other. Figure 5 As shown, the interior of the detection slot 201 is fixedly installed with a horizontally arranged linear guide rail 3, such as Figure 6 As shown, the top of the linear guide rail 3 is driven to install a central electric slider 4 and two side electric sliders 5, and the two side electric sliders 5 are distributed on both sides of the central electric slider 4. Figure 7 As shown, a middle supporting platform 6 is fixedly installed on the top of the middle electric slider 4. Figure 8As shown, a fixed plate 7 is fixedly installed on the top of the side wing electric slider 5, a flip plate 8 is arranged on the top of the fixed plate 7, a fixed bracket 9 is fixedly installed on one side of the fixed plate 7 close to the middle supporting platform 6, a horizontally arranged flip shaft 11 is rotatably installed on the fixed bracket 9, a flip bracket 10 is fixedly installed on the flip shaft 11, one end of the flip bracket 10 located on the same side is fixedly installed on the side wall of the flip plate 8, a flip motor 12 is fixedly installed on one side of the fixed plate 7, the output shaft of the flip motor 12 located on the same side is drivingly connected to one end of the flip shaft 11, and the middle supporting platform 6 and the top of the flip plate 8 are fixedly installed with an ultrasonic detector 13. In this embodiment, the vehicle chassis height detection device is arranged at the main entrance of the garage or on one side of the three-dimensional garage, and needs to be used in conjunction with the visual recognition system. By arranging a camera at a high position on one side of the concrete frame 2, the relative position of the vehicle to be detected and the concrete frame 2 is detected and identified; specifically, when the vehicle chassis height detection device for the three-dimensional garage is in use, the driver stops after driving the vehicle onto the concrete frame 2, and the camera above one side of the concrete frame 2 detects the position of the vehicle, and then Control each side electric slider 5 and the middle supporting platform 6 to move along the linear guide rail 3, so that each ultrasonic detector 13 moves to various positions of the front, body and rear of the vehicle respectively, so that the ultrasonic detector 13 located in the middle moves to the bottom of the vehicle, and at the same time, the ultrasonic detectors 13 on both sides move close to the two sides of the vehicle, and then the flip motors 12 on both sides drive the flip shaft 11 to rotate, and then drive the flip plate 8 to flip toward the vehicle through the flip bracket 10, so that the ultrasonic detectors 13 on both sides are inclined upward toward the vehicle chassis, and at this time, each ultrasonic detector 13 starts to start and moves toward Ultrasonic waves are emitted to and received from the chassis of the vehicle. The lowest point of the chassis of the vehicle is determined by the wavelength of the sound wave and the time difference between the emitted sound wave and the received return sound wave. The approximate height of the lowest point is calculated to obtain the current chassis height of the vehicle. Since the propagation speed of ultrasonic waves on common garbage such as fallen leaves and packaging bags attached to the chassis of the vehicle is significantly different from that on the chassis of the vehicle, the garbage on the chassis of the vehicle will not have a significant impact on the measurement results. At the same time, the system avoids the problems of rigid settings, inconvenient height adjustment ranges, and susceptibility to weather effects of current optical measuring instruments.

The camera on one side of the concrete frame 2 detects the position of the vehicle, and the vacuum cleaner 22 is started synchronously, and a strong suction force is generated on the inside of the detection slot 201 through the vacuum pipe 23, the vacuum wide plate 24 and each vacuum hole 204, so that the middle folded dustproof cloth 15, the side folded dustproof cloth 17 and each control bracket 1 9, a small amount of dust attached to the vehicle is sucked away, and then each side electric slider 5 and the middle supporting platform 6 move along the linear guide rail 3, so that each ultrasonic detector 13 moves to various positions of the front, body and rear of the vehicle, so that the ultrasonic detector 13 located in the middle moves to the bottom of the vehicle, and at the same time, the ultrasonic detectors 13 on both sides move close to the two sides of the vehicle, and the dustproof electric push rod 18 drives the dustproof plate 20 to retract into the sealing accommodating hole 202, and then the flip motors 12 on both sides drive the flip shaft 11 to rotate, and then drive the flip plate 8 to flip toward the vehicle through the flip bracket 10, so that the ultrasonic detectors 13 on both sides are inclined upward toward the vehicle chassis, and when the position adjustment of the ultrasonic detector 13 is completed, the vacuum cleaner 22 stops dust suction; During detection: each ultrasonic detector 13 starts to start and emits and receives ultrasonic waves toward the chassis of the vehicle, and uses the wavelength of the sound wave and the time difference between the emission of the sound wave and the reception of the return sound wave to determine the lowest point of the chassis of the vehicle, and calculates the approximate height of the lowest point, thereby obtaining the current chassis height of the vehicle; After detection: the dustproof electric push rod 18 inside the dust suction groove will drive the dustproof plate 20 to slide along the sealing accommodating hole 202 toward the inside of the detection groove 201 through the control bracket 19, so that the sealing accommodating hole 202 slides into the sealing slide groove 203 and until the top of the detection groove 201 is completely covered, so that the detection groove 201 is closed, so that the dustproof plate 20 can play a protective, dust-proof and moisture-proof role when the detection device is idle. When the vacuum cleaner 22 works for a long time or the components inside the dust suction groove are damaged, the maintenance personnel can open the inspection door 26 from the outside to inspect the components inside the dust suction groove, and can open the vacuum cleaner 22 storage and replacement door 25 to clean and replace the dust collecting bag inside the vacuum cleaner 22 to maintain the dust suction performance of the vacuum cleaner 22.
