Technical Field

[0001] This utility model relates to the field of intelligent transportation technology, specifically to a vehicle identification device for new energy vehicle carports. Background Technology

[0002] With the booming development of the new energy vehicle industry and the continuous increase in the number of new energy vehicles, the traditional carport management model can no longer meet the needs of efficient and precise management. At present, most new energy vehicle carports still rely on manual operation or simple sensing equipment in the management of vehicle entry and exit and the allocation of charging resources, which has problems such as low efficiency, easy error and unreasonable resource utilization.

[0003] In the prior art, it is impossible to distinguish between hybrid and pure new energy vehicles in detail, which means that parking spaces with charging facilities in carports often cannot effectively serve pure new energy vehicles. Hybrid vehicles occupy parking spaces with charging facilities when they do not need to be charged, which makes parking spaces needed by pure new energy vehicles scarce. Therefore, those skilled in the art provide a vehicle identification device for new energy vehicle carports to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle identification device for new energy vehicle carports, which solves the problem that existing technologies cannot distinguish new energy vehicles in detail.

[0006] The testing mechanism includes a load-bearing plate fixedly connected to the bottom of one side of the testing box. An installation hole is provided on the upper surface of the load-bearing plate opposite to the testing box. An expansion groove is fixedly connected in the installation hole. A connecting pipe is connected to the bottom center of the expansion groove. An air extraction groove is provided in the load-bearing plate. The air extraction groove is located directly below the expansion groove. The connecting pipe is fixedly installed on the top inner wall of the air extraction groove. An electric valve is fixedly installed at the connection between the expansion groove and the connecting pipe.

[0007] As a preferred embodiment of the above technical solution, the end of the connecting pipe opposite to the expansion tank passes through the detection box and is connected to an air extraction cylinder. An air outlet pipe is connected to the center of the upper surface of the air extraction cylinder. A gas detector is fixedly installed at the end of the air outlet pipe opposite to the air extraction cylinder. Two electric telescopic rods are symmetrically fixedly installed at the top inside the air extraction cylinder, and the telescopic ends of the two electric telescopic rods are fixedly connected to a piston plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses an electric telescopic rod and piston plate to draw air from the connecting pipe of the air extraction cylinder. The connecting pipe, together with the expansion tank, draws air from below the rear of the vehicle. With the help of a gas detector, the composition of the air below the rear of the vehicle can be detected. By analyzing the composition of the air, hybrid vehicles and pure new energy vehicles can be identified and distinguished, so as to better guide vehicles into the corresponding parking sheds and prevent hybrid vehicles from occupying parking spaces that are only for pure new energy vehicles, thereby reducing the shortage of parking spaces for pure new energy vehicles.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-5 As shown, this utility model provides a technical solution: a vehicle identification device for a new energy vehicle canopy, including a detection box 1, an identification mechanism 2 is provided on the top of the detection box 1, and a detection mechanism 4 is provided on the bottom of one side of the detection box 1;

[0024] The testing mechanism 4 includes a load-bearing plate 41 fixedly connected to the bottom of one side of the testing box 1. A mounting hole is provided on the upper surface of the load-bearing plate 41 away from the center line of the end opposite to the testing box 1. An expansion groove 42 is fixedly connected in the mounting hole. A connecting pipe 43 is connected to the bottom center of the expansion groove 42. An air extraction groove 44 is provided in the load-bearing plate 41. The air extraction groove 44 is located directly below the expansion groove 42. The connecting pipe 43 is fixedly installed on the top inner wall of the air extraction groove 44. An electric valve 421 is fixedly installed at the connection between the expansion groove 42 and the connecting pipe 43.

[0025] In practice, the entire structure is made of high-strength stainless steel, with a rust-proof surface treatment, providing excellent durability and impact resistance to adapt to complex and changing working environments. The load-bearing plate 41 is securely welded to the side and bottom of the testing box 1, ensuring no loosening or displacement during prolonged use. The load-bearing plate 41 is made of high-strength alloy material, possessing excellent load-bearing capacity and compressive strength. The expansion tank 42 is cylindrical, made of corrosion-resistant polytetrafluoroethylene (PTFE), and has a large internal space, capable of holding a large number of gas samples, providing ample space for gas collection and temporary storage. A connecting pipe 43 is tightly connected to the bottom center of the expansion tank 42 via a threaded connection. The connecting pipe 43 is also made of corrosion-resistant material, with smooth walls to facilitate smooth gas flow.

[0026] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the end of the connecting pipe 43 away from the expansion tank 42 passes through the detection box 1 and is connected to the suction cylinder 45. The center of the upper surface of the suction cylinder 45 is connected to the exhaust pipe 46. The end of the exhaust pipe 46 away from the suction cylinder 45 is fixedly installed with a gas detector 47. Two electric telescopic rods 48 are symmetrically fixedly installed at the top inside the suction cylinder 45. The two electric telescopic rods 48 are fixedly connected to a piston plate 49.

[0027] In practice, the connecting pipe 43 is fixedly installed on the top inner wall of the suction tank 44 by welding to ensure that no leakage occurs during gas transmission. The end of the connecting pipe 43 away from the expansion tank 42 passes through the box wall of the detection box 1 and is stably connected to the suction cylinder 45 through a sealing joint. This connection method ensures gas flow and prevents outside air from interfering with the detection results. The gas detector 47 has high-precision detection capabilities and can quickly and accurately analyze various components and their concentrations in the gas sample. The piston plate 49 is finely processed and can slide against the inner wall of the suction cylinder 45. Its surface is coated with a special lubricating material, which ensures smooth sliding and enhances sealing.

[0028] As one implementation method in this embodiment, please refer to Figures 3-4 As shown, the piston plate 49 slides against the inner wall of the vacuum cylinder 45, and a one-way valve 410 is fixedly installed at the center of the piston plate 49.

[0029] In practice, the one-way valve 410 allows gas in the lower chamber of the piston plate 49 in the suction cylinder 45 to enter the upper chamber of the piston plate 49, effectively preventing gas backflow and ensuring that the gas sample can smoothly enter the gas detector 47 for detection. When the electric telescopic rod 48 moves the piston plate 49 to extract the gas sample, the one-way valve 410 will automatically open, and the gas will be quickly delivered to the gas detector 47 through the suction cylinder 45 and the outlet pipe 46. When the electric valve 421 is closed, the piston plate 49 is reset, and the gas is squeezed to further enter the gas detector 47, avoiding errors in the detection results due to insufficient sample.

[0030] As one implementation method in this embodiment, please refer to Figures 1-2 As shown, the identification mechanism 2 includes a mounting box 21 fixedly installed on one end of the upper surface of the detection box 1. A servo motor 26 is fixedly installed inside the mounting box 21. A rotating block 22 is fixedly connected to the output end of the servo motor 26. A camera 23 is fixedly installed on the rotating block 22. A rotating shaft 24 is fixedly connected to the end of the rotating block 22 away from the servo motor 26. A mounting plate 25 is fixedly connected to the upper surface of the detection box 1 away from the mounting box 21. The end of the rotating shaft 24 away from the rotating block 22 rotates on the top of the mounting plate 25.

[0031] In practice, the output end of the servo motor 26 is coaxially and fixedly connected to the rotating block 22 via a coupling, ensuring stable and efficient power transmission.

[0032] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a grid plate 3 is fixedly installed on the top of the detection box 1.

[0033] In practice, by setting up the grid plate 3, the interior of the installation box 1 can be connected to the outside air. After the test is completed, the gas detector 47 releases the gas that has been tested and connects with the air inside the installation box 1, thereby balancing the air pressure in the vacuum cylinder 45 and causing the installation plate 25 to reset.

[0034] As one implementation method in this embodiment, please refer to Figure 3 As shown, an intelligent controller 5 is fixedly installed on the top inner wall of the detection box 1.

[0035] In practice, the intelligent controller 5 integrates an advanced microprocessor and control chip. It can automatically control the rotation of the servo motor 26, the extension and retraction of the electric telescopic rod 48, and the data acquisition and analysis of the gas detector 47 according to the preset program and detection requirements, so as to realize the automation and intelligence of the entire detection process. The gas detector 47 is an existing structure and will not be described in detail here.

[0036] Working principle: First, when a vehicle drives into the carport and crushes the load-bearing plate 41 at the bottom of the detection box 1, the load-bearing plate 41 triggers the detection mechanism 4 to start. The expansion groove 42 in the mounting hole is connected to the air extraction groove 44 through the connecting pipe 43. Two electric telescopic rods 48 drive the piston plate 49 to slide in the air extraction cylinder 45. The one-way valve 410 creates negative pressure, and the air is extracted from the bottom of the vehicle to the exhaust pipe 46 through the air extraction cylinder 45 and the connecting pipe 43. The gas detector 47 detects the gas composition and closes the electric valve 421. The piston plate 49 resets and squeezes the gas downward to further enter the gas detector 47. At the same time, the servo motor 26 of the identification mechanism 2 above the detection box 1 drives the rotating block 22 to rotate through the rotating shaft 24, adjusting the angle of the camera 23 to collect vehicle images. The intelligent controller 5 processes the gas detection data and image recognition data simultaneously, thereby identifying and distinguishing different types of vehicles, and further distinguishing new energy vehicles based on the gas detection results.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
