[0001] The present invention relates to the technical field of vehicle detection, and particularly to a vehicle height and width detection device for a stereoscopic garage. Background Art

[0002] With the rapid increase in the number of automobiles, the parking problem has become increasingly prominent. The emergence of stereoscopic garages has effectively alleviated the shortage of parking spaces. However, it also poses higher requirements for the parking skills of car owners. The parking space sizes of stereoscopic garages usually have certain limitations. The width of a standard parking space is generally between 2.2 - 2.5 meters, and the length is 5 meters. The width of the parking space of a mechanical parking device is approximately between 2.25 - 2.3 meters. In addition, the net height requirement for stereoscopic garages is also relatively high, usually not less than 3.6 meters. Therefore, in order to ensure that vehicles can enter and exit smoothly, a variety of detection devices are generally installed at the entrances and exits of stereoscopic garages to detect the external dimensions of vehicles.

[0015] Such as Figures 1 to 11As shown in the figure, a vehicle height and width detection device for a three-dimensional garage includes two vertically arranged gantry frames 1, as Figure 1 shown, a same dust-proof outer cover 2 is fixedly installed between the two gantry frames 1, as Figure 2 , Figure 3 shown, a first horizontal traveling platform 3 and a second horizontal traveling platform 4 arranged in parallel are fixedly installed between the two gantry frames 1. Both the first horizontal traveling platform 3 and the second horizontal traveling platform 4 are located inside the dust-proof outer cover 2, as Figure 4 shown, horizontal support frames 5 are fixedly installed on one side of the first horizontal traveling platform 3 and the second horizontal traveling platform 4 close to each other, as Figure 6 , Figure 7 shown, two horizontally arranged transmission gear rollers 6 and a plurality of support rollers 8 are rotatably installed between the two horizontal support frames 5. The plurality of support rollers 8 are all located between the two transmission gear rollers 6. The same transmission toothed belt 7 is tensioned on the two transmission gear rollers 6. The plurality of support rollers 8 are all located inside the transmission toothed belt 7. Cleaning and detection components are arranged on the tops of the first horizontal traveling platform 3 and the second horizontal traveling platform 4. The cleaning and detection components are used for cleaning the vehicle and detecting the outer contour of the vehicle body. The two cleaning and detection components are symmetrically distributed on both sides of the transmission toothed belt 7, as Figure 8 shown, the cleaning and detection components include two horizontal linear modules 9 fixedly installed on the tops of the first horizontal traveling platform 3 and the second horizontal traveling platform 4, as Figure 9 shown, the tops of the driving ends of the horizontal linear modules 9 are all fixedly installed with support plates 10. In this embodiment, the horizontal linear module 9 can be a common linear motion actuator in the prior art, such as a linear guide rail, an electric slide table, a ball screw, etc. Its driving end can carry the support plate 10 to travel above the first horizontal traveling platform 3. A vertically arranged C-shaped frame 11 is slidably installed on the top of the support plate 10. Two horizontally arranged adjusting electric push rods 12 are fixedly installed on the top of the support plate 10. The two adjusting electric push rods 12 are distributed on both sides of the C-shaped frame 11. The telescopic ends of the adjusting electric push rods 12 are all fixedly connected to the bottom end of the C-shaped frame 11, as Figure 8 shown, a vertically arranged cleaning roller 13 is rotatably installed inside the C-shaped frame 11, as Figure 10 , Figure 11 shown, a plurality of uniformly distributed pressure measuring grooves 1301 are formed on the circumferential side of the cleaning roller 13. Pressure measuring rods 14 are rotatably installed inside the pressure measuring grooves 1301. Cleaning brushes 15 are fixedly installed at one ends of the pressure measuring rods 14. Pressure sensors 16 are fixedly installed inside the pressure measuring grooves 1301. The sensing ends of the pressure sensors 16 are all in contact with the pressure measuring rods 14, as Figure 2 shown, a motor box 17 is fixedly installed at the top end of the C-shaped frame 11, as Figure 8As shown, a cleaning motor 18 is fixedly installed inside the motor box 17, and the output shaft of the cleaning motor 18 is drivingly connected to the cleaning roller 13; specifically, when this vehicle height and width detection device for a three-dimensional garage is in use, the vehicle is guided into the interior of the dust-proof outer cover 2 through one of the gantry frames 1 and parks on the transmission toothed belt 7. At this time, the cleaning and detection components on both sides are located on one side of the vehicle head. The horizontal linear modules 9 on both sides drive the support plate 10 to carry the C-shaped frame 11 and the cleaning roller 13 towards the vehicle. At the same time, the adjusting electric push rod 12 drives the C-shaped frame 11 to slide on the support plate 10, so that the cleaning roller 13 and the cleaning brush 15 array approach the vehicle body. The cleaning motor 18 at the top of the C-shaped frame 11 drives the two cleaning rollers 13 to start rotating. When the two cleaning rollers 13 pass by both sides of the vehicle, the rotating cleaning brush 15 array will sweep the dust and sundries on both sides and the top of the vehicle body. When the cleaning brush 15 touches the vehicle body, the cleaning brush 15 and the pressure measuring rod 14 will receive the reaction force of the vehicle body, thereby driving the pressure measuring rod 14 to generate a rotational tendency, so that the pressure sensor 16 in contact with the pressure measuring rod 14 receives pressure and generates a pressure signal. Thus, the outline of the vehicle can be measured according to the position of the pressure sensor 16 where the signal is generated, and data such as the height and width of the vehicle can be obtained in cooperation with devices such as ultrasonic sensors and infrared sensors. The contact detection is used to make up for the defect that the traditional sensor detection is easily affected by environmental factors, and at the same time, the vehicle is cleaned to prevent dust and sundries from being carried into the three-dimensional garage by the vehicle, affecting the operation of the three-dimensional garage. After the detection is completed, the vehicle continues to drive, enters the area where the three-dimensional garage is located through the dust-proof outer cover 2 on the other side, and completes the detection.

[0016] As Figure 3 shown, a vacuum cleaner 19 is fixedly installed on one side of the C-shaped frame 11. The dust suction end of the vacuum cleaner 19 is fixedly installed with a C-shaped horizontal dust suction pipe 20. The two ends of the C-shaped horizontal dust suction pipe 20 are respectively located on both sides of the cleaning roller 13 and both face above the transmission toothed belt 7. As Figure 8 shown, vertical dust suction pipes 21 are fixedly installed at the bottoms of both ends of the C-shaped horizontal dust suction pipe 20, and the vertical dust suction pipes 21 all face the horizontal linear module 9; specifically, by setting the vacuum cleaner 19, when the cleaning and detection components perform mobile detection, the vacuum cleaner 19 is started synchronously, so that the dust, sundries, etc. swept off the vehicle body by the cleaning roller 13 will be sucked into the vacuum cleaner 19 through the C-shaped horizontal dust suction pipe 20 and stored, thereby preventing dust and sundries from accumulating inside the dust-proof outer cover 2. At the same time, the vacuum cleaner 19 will suck the dust falling from the top of the horizontal linear module 9 through the vertical dust suction pipe 21, preventing the accumulation of dust from affecting the transmission of the horizontal linear module 9.

[0017] As Figure 5As shown in the figure, at both ends inside the first horizontal traveling platform 3, horizontally arranged limit electric push rods 22 are fixedly installed. Linkage frames 23 are fixedly installed at the telescopic ends of the limit electric push rods 22. A limit sliding frame 24 is arranged on one side of the limit electric push rod 22. The limit sliding frame 24 is fixedly installed inside the first horizontal traveling platform 3. A limit multi-sided insertion rod 25 is slidably installed inside the limit sliding frame 24. The limit multi-sided insertion rod 25 is fixedly connected to the limit multi-sided insertion rod 25. As Figure 7 shown, at one end of the transmission gear roller 6 located inside the first horizontal traveling platform 3, limit insertion cylinders 26 are fixedly installed. The limit insertion cylinders 26 are adapted to the limit multi-sided insertion rods 25. As Figure 5 shown, a laser receiver 27 is fixedly installed on the linkage frame 23. As Figure 7 shown, a laser emitter 28 adapted to the laser receiver 27 is fixedly installed on the side wall of the limit insertion cylinder 26. As Figure 4 shown, at both ends inside the second horizontal traveling platform 4, transposition motors 34 are fixedly installed. The output shafts of the two transposition motors 34 are respectively drivingly connected to the other ends of the two transmission gear rollers 6. In this embodiment, no self-locking mechanism is provided inside the transposition motor 34; specifically, by providing the limit insertion cylinders 26, when the vehicle drives into the gantry 1, in the initial state, one ends of the two limit multi-sided insertion rods 25 are respectively inserted into the two limit insertion cylinders 26, and the other ends still remain inside the limit sliding frame 24, so that the two transmission gear rollers 6 are locked and cannot rotate, thereby keeping the transmission belt 7 stationary, so that the vehicle can pass above the transmission belt 7. Before the cleaning and detection assembly detects, the limit electric push rod 22 will drive the limit multi-sided insertion rod 25 to disengage from the limit insertion cylinder 26, releasing the lock on the transmission gear roller 6, so that the transmission belt 7 can move with the rotation of the wheels, restricting the movement of the vehicle to prevent the vehicle from moving by itself or directly entering the area where the garage is located during the detection process. After the vehicle leaves, if the rotation of the transmission gear roller 6 causes the limit insertion cylinder 26 and the limit multi-sided insertion rod 25 to be misaligned, the transposition motors 34 inside the second horizontal traveling platform 4 will respectively drive the two transmission gear rollers 6 to slowly rotate until the laser emitter 28 on the limit insertion cylinder 26 is docked with the laser receiver 27, completing the positioning of the limit multi-sided insertion rod 25 and the limit insertion cylinder 26. At this time, the limit electric push rod 22 drives the limit multi-sided insertion rod 25 to insert into the limit insertion cylinder 26 again to lock the transmission gear roller 6 and the transmission belt 7.

[0018] As Figure 2As shown, a plurality of evenly distributed ultrasonic scanners 29 are fixedly mounted on the inner wall of one of the gantries 1, two symmetrically arranged vertical linear modules 30 are fixedly mounted on one side of one of the gantries 1, and a laser rangefinder 31 is fixedly mounted on the driving end of each of the vertical linear modules 30. In this embodiment, the vertical linear module 30 can be a common linear motion actuator in the prior art, such as a linear guide, an electric slide, a ball screw, etc., and its driving end can carry the laser rangefinder 31 and move vertically on one side of the gantry 1. The ultrasonic scanner 29 and the vertical linear module 30 are installed on the same gantry 1, and the gantry 1 is arranged at the outermost side of the entrance of the stereo garage, as shown in FIG. Figure 1 As shown, a blocking gate 32 and an anti-collision pile 33 are provided on one side of the gantry 1, and the blocking gate 32 and the anti-collision pile 33 correspond to the positions of the two vertical linear modules 30 respectively; specifically, by arranging an ultrasonic scanner 29 and a laser rangefinder 31, when the vehicle enters the dustproof cover 2, the laser rangefinders 31 on both sides will move up and down first to pre-detect the vehicle, and at the same time, multiple ultrasonic scanners 29 will also scan the vehicle body, so as to obtain approximate data of the vehicle body outline and the vehicle's traveling direction, so as to cooperate with the cleaning detection component to detect the accurate vehicle body size, and at the same time provide a reference for adjusting the spacing of the cleaning detection components. The blocking gate 32 arranged outside the gantry 1 can identify the vehicle, play a role in guiding and intercepting, and at the same time cooperate with the anti-collision pile 33 on the other side to protect the vertical linear module 30 to prevent the vertical linear module 30 from colliding with the vehicle.

[0019] In summary: Before detection: In the initial state, one end of the two limit polygonal plug rods 25 is respectively inserted into the inside of the two limit plug cylinders 26, and the other end is still located in the inside of the limit slide 24, so that the two transmission gear rollers 6 are locked and cannot rotate, so that the transmission toothed belt 7 remains stationary. The vehicle is guided from one of the gantry frames 1 into the inside of the dustproof cover 2 and stops on the transmission toothed belt 7. In the process of the vehicle entering the inside of the dustproof cover 2, the laser rangefinders 31 on both sides will move up and down first to pre-detect the vehicle, and at the same time, multiple ultrasonic scanners 29 will also scan the vehicle body. Scanning, thereby obtaining the approximate data of the vehicle body outline and the vehicle's traveling direction, so as to cooperate with the cleaning detection component to detect the accurate body size, and at the same time provide a reference for adjusting the spacing of the cleaning detection components. Before the cleaning detection component detects, the limit electric push rod 22 will drive the limit polygonal plug rod 25 to disengage from the limit plug cylinder 26, unlocking the transmission gear roller 6, so that the transmission gear belt 7 can move with the rotation of the wheel, restricting the movement of the car, and preventing the vehicle from moving by itself or directly entering the garage area during the detection process. At this time, the cleaning detection components on both sides are located on one side of the front of the car; During detection: When detecting, the horizontal linear modules 9 on both sides drive the support plate 10 to carry the C-shaped frame 11 and the cleaning roller 13 towards the vehicle. At the same time, the adjustable electric push rod 12 drives the C-shaped frame 11 to slide on the support plate 10, so that the cleaning roller 13 and the cleaning brush array 15 approach the vehicle body. The cleaning motor 18 at the top of the C-shaped frame 11 drives the two cleaning rollers 13 to start rotating. When the two cleaning rollers 13 pass by both sides of the vehicle, the rotating cleaning brush array 15 will sweep the dust and sundries on both sides and the top of the vehicle body. When the cleaning brush 15 contacts the vehicle body, the cleaning brush 15 and the pressure measuring rod 14 will receive the reaction force of the vehicle body, thereby driving the pressure measuring rod 14 to generate a rotation trend, so that the pressure sensor 16 in contact with the pressure measuring rod 14 receives pressure and generates a pressure signal. Thus, the outer contour of the vehicle can be measured according to the position of the pressure sensor 16 where the signal is generated. When the cleaning and detection assembly performs mobile detection, the vacuum cleaner 19 is started synchronously, so that the dust, sundries, etc. swept down by the cleaning roller 13 on the vehicle body will be sucked into the vacuum cleaner 19 through the C-shaped horizontal suction pipe 20 and stored, thus avoiding the accumulation of dust and sundries inside the dust-proof outer cover 2. At the same time, the vacuum cleaner 19 will suck the dust falling from the top of the horizontal linear module 9 through the vertical suction pipe 21; After detection: After the detection is completed, the vehicle continues to drive, enters the area where the three-dimensional garage is located through the dust-proof outer cover 2 on the other side, and completes the detection. After the vehicle leaves, if the rotation of the transmission gear roller 6 causes the limit insertion cylinder 26 to be misaligned with the limit multi-sided insertion rod 25, the transposition motor 34 inside the second horizontal traveling platform 4 will drive the two transmission gear rollers 6 to rotate slowly until the laser emitter 28 on the limit insertion cylinder 26 is docked with the laser receiver 27, completing the positioning of the limit multi-sided insertion rod 25 and the limit insertion cylinder 26. At this time, the limit electric push rod 22 drives the limit multi-sided insertion rod 25 to insert into the limit insertion cylinder 26 again to lock the transmission gear roller 6 and the transmission belt 7.
