Technical Field

[0001] This application relates to the field of measurement technology for suspension or shock absorption mechanisms, and more particularly to a height detection device for an intelligent rail air spring. Background Technology

[0002] Intelligent Rail Transit (IRT), as an emerging medium- and low-capacity rail transit system, has shown a strong momentum of development in both domestic and international markets. However, due to its relatively late start, there is a lack of mature maintenance experience to draw upon, and related technical reserves are still insufficient. In the field of vehicle maintenance, it is still in a stage of continuous exploration and accumulation, which undoubtedly places more stringent demands on vehicle maintenance work. As a core component of the IRT vehicle's suspension system, the accurate measurement of the air spring's height directly affects the vehicle's operational safety and performance. However, the complex and varied irregular structure of the IRT air spring, coupled with extremely limited operating space on the sides and under the vehicle, presents a significant challenge to traditional measurement methods.

[0003] Currently, common measurement methods mainly rely on manual measurement using simple tools such as measuring tapes. This method requires operators to work in confined spaces, making it difficult to guarantee measurement accuracy and efficiency. Furthermore, it necessitates multiple measurements and averaging. Manual measurement is also significantly affected by human factors, resulting in inconsistent accuracy and making it difficult to achieve high precision requirements. Utility Model Content

[0039] refer to Figures 1-6This utility model discloses a height detection device for an air spring in a smart rail system, comprising: a main unit 1 and a reflector 2. The main unit 1 is detachably connected to one end of the air spring 3, and the reflector 2 is detachably connected to the other end of the air spring 3. The main unit 1 emits ultrasonic waves and / or lasers, which are reflected by the reflector 2 and received by the main unit 1. In this way, the height of the air spring can be measured. During measurement, the main unit and reflector are simply fixed to the upper and lower end faces of the air spring, and laser and / or ultrasonic measurement methods are used. The operation is simple and the measurement accuracy is high. This solves the problems of existing technologies, such as the high difficulty of manual measurement using simple tools like measuring tapes, the inability to guarantee measurement accuracy and efficiency, the need for multiple measurements and averaging, the cumbersome operation, the large time consumption, and the significant influence of human factors on the accuracy of manual measurement, making it difficult to achieve high precision requirements.

[0040] The main unit 1 includes: housing 11, fixing block 12, ultrasonic ranging module 13 and / or laser ranging module 14;

[0041] The fixing block 12 is fixedly connected to the lower surface of the housing 11. The fixing block 12 is detachably connected to the air spring 3. The ultrasonic ranging module 13 and / or the laser ranging module 14 are disposed inside the housing 11. The transmitting end and receiving end of the ultrasonic ranging module 13 and / or the laser ranging module 14 are disposed on the lower surface of the housing.

[0042] The ultrasonic ranging module 13 is the HC-SR04 ultrasonic ranging module, and the laser ranging module 14 is either the MS53L0M laser ranging module or the Panasonic HG-C1050.

[0043] The ultrasonic ranging module 13 and the laser ranging module 14 can accurately capture changes in the height of the air spring and convert them into electrical signals for output, making the measurement accurate and efficient.

[0044] To facilitate the fixing and disassembly of the main unit 1 and the air spring 3, the fixing block 12 is a magnet, which is fixedly connected to the lower surface of the housing 11 by screws. In use, the main unit 1 is placed on top of the air spring 3, and the magnet attracts the metal at the upper end of the air spring 1, stably fixing the main unit 1 to the air spring 3. After use, the main unit 1 can be removed with slight force. This connection method makes the connection and disassembly of the main unit 1 and the air spring 3 simple and reliable.

[0045] To make the main unit 1 more securely fixed, the fixing block 12 includes a first magnet 121 and a second magnet 122; the housing 11 is provided with steps, and the first magnet 121 and the second magnet 122 are fixedly connected to different steps (such as...). Figure 3 (As shown). In this way, the first magnet 121 and the second magnet 122 can be attracted to the metal step at the upper end of the air spring 3, making the attraction more stable.

[0046] To improve the accuracy of air spring height measurement, the intelligent rail air spring height detection device includes an ultrasonic ranging module 13 and a laser ranging module 14. During use, the ultrasonic ranging module 13 and the laser ranging module 14 work together. If their measurement results are similar, the average of the two is taken. If the measurement results differ significantly, it indicates a product malfunction or incorrect usage.

[0047] For ease of carrying or storage, an L-shaped groove 25 is provided on the lower surface of the reflector 2, and an L-shaped protrusion 15 is provided on the upper surface of the main unit 1. When carrying or storing, simply insert the L-shaped groove 25. When in use, simply pull the L-shaped protrusion 15 out of the L-shaped groove 25. Preferably, there are two L-shaped grooves 25, located on both sides of the reflector; and two L-shaped protrusions 15, located on both sides of the upper surface of the main unit 1.

[0048] To facilitate the fixing and disassembly of the reflector 2 and the air spring 3, the reflector 2 is a thin plate, and a third magnet 21 is fixed on the upper surface of the reflector 2. In use, the third magnet 21 on the reflector 2 is attracted to the metal at the lower end of the air spring 3, which fixes the reflector 2 to the lower end of the air spring 3. After use, the reflector 2 can be easily removed, making it convenient and reliable to use.

[0049] To make the reflector plate 2 more secure, the reflector plate 2 is T-shaped, including a crossbeam 22 and a vertical plate 23. The crossbeam 22 and the vertical plate 23 are integrally formed, consisting of 2-3 pieces. The third magnet 21 is set at the crossbeam (22) of the reflector plate 2, and the vertical plate is for reflecting ultrasonic waves and lasers.

[0050] To ensure a more stable fixation of the reflector, strip plates 24 are fixed to both ends of the crossbeam 22 of the reflector 2. In this way, although the vertical plate 23 is relatively heavy and tends to move downwards under the action of gravity, the strip plates 24 play a role in maintaining stability, and the two strip plates 24 will not interfere with the support structure at the lower end of the air spring.

[0051] The present invention discloses a smart rail air spring height detection device, the operation method of which is as follows:

[0052] 1. Remove the intelligent rail spring height detection device. The current state is as follows: Figure 6 As shown, the reflector 2 and the main unit 1 are disassembled;

[0053] 2. Place the main unit 1 on the upper end of the air spring 3 so that the first magnet 121 and the second magnet 122 can be attracted to the metal step on the upper end of the air spring 3;

[0054] 3. Place the reflector 2 at the lower end of the air spring 3, so that the third magnet 21 is attracted to the metal at the lower end of the air spring 3, and begin the measurement. Figure 1 As shown;

[0055] 4. After the measurement is completed, remove the main unit 1 and the reflector 2, insert the L-shaped protrusion 15 of the reflector 2 into the L-shaped groove 25, and the work is finished.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
