Description

Technical Field

[0001] The present invention belongs to the technical field of bus bodies, and specifically relates to a steering positioning detection mechanism for non-plated low-carbon steel buses. Background Art

[0002] With the continuous development of the machinery manufacturing industry, the application scenarios of bus bodies have increased, and the requirements for safety have also been continuously improved. Large bus bodies can be used for container transfer in yards. Due to the use of a tire-type large vehicle mechanism, they can transfer sites very flexibly, greatly improving the usage efficiency of large bus bodies.

[0003] When large bus bodies are in use, radar sensors are installed on both sides. The radar sensors can monitor the steering position and speed of the large vehicle in real time, ensuring that the large vehicle can move accurately and stably during the steering process. Also, through the monitoring of the radar sensors, it can be determined whether the large vehicle will collide with surrounding obstacles. If there is a collision risk, the radar sensors will promptly transmit the information to the control system, thus avoiding the occurrence of collision accidents.

[0004] Most of the existing radar sensors are installed on the vehicle frame by screws. When overhauling the radar sensors, it is necessary to twist and disassemble the screws. Due to being exposed to the outdoors for a long time, exposed to sunlight and rain, the screws may be rusty, making disassembly or installation inconvenient.

[0005] Therefore, a steering positioning detection mechanism for non-plated low-carbon steel buses is proposed. Summary of the Invention

[0006] The purpose of the present invention is: to improve the efficiency and convenience of disassembling or installing radar sensors, the present application provides a steering positioning detection mechanism for non-plated low-carbon steel buses.

[0007] The technical solution adopted by the present invention is as follows: A steering positioning detection mechanism for non-plated low-carbon steel buses, including a bus body main body, a steering positioning detection mechanism, and an installation mechanism. The lower surfaces at both ends of the bus body main body are fixedly connected with vehicle frame bases. The steering positioning detection mechanism is arranged on the outer side of the vehicle frame bases. Fixed insertion plates are provided on both side surfaces of the vehicle frame bases, and clamping grooves are opened on the upper and lower surfaces of the insertion plates; The steering positioning detection mechanism includes an installation seat. A slot is opened on one side surface of the installation seat. The outer surface of the insertion plate is inserted into the inner surface of the slot. A radar sensor is fixedly connected to the side surface of the installation seat away from the slot. An inner groove is opened on the inner side wall of the slot, and through holes are opened on the inner wall of the inner groove; The installation mechanism includes two springs. The two springs are fixedly connected to the inner walls of the inner grooves on both sides of the through hole. One end of each spring close to the slot is fixedly connected with a clamping post. One side surface of the clamping post away from the slot is fixedly connected with a pull rod. One end of the pull rod away from the clamping post passes through the through hole and is fixedly connected with a pulling block.

[0008] Further, inclined jacks are formed on the lower surfaces of the pulling blocks on both sides of the pull rod. Positioning rods are hinged to the outer surfaces of the mounting seats on both sides of the through hole.

[0009] Further, the outer diameter of the positioning rod is adapted to the inner diameter of the inclined jack.

[0010] Further, the outer surface of the clamping post is slidably connected to the inner surface of the inner groove, and the outer diameter of the clamping post is adapted to the inner diameter of the card slot.

[0011] Further, a plurality of wheels are installed on the lower surface of the passenger car body. A cab is fixedly connected to the upper surface of the right frame base.

[0012] Further, a power supply box, a controller, an operating table and a display screen are arranged inside the cab. The output end of the power supply box is electrically connected to the controller, the display screen and the radar sensor. The output end of the radar sensor is electrically connected to the controller and the power supply of the display screen.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1. In the present invention, when installing the radar sensor after maintenance, the pulling block can be first pulled to drive the pull rod to compress the spring so that the clamping post can completely slide into the inner groove. Then, the insertion plate can be inserted into the slot. Then, the pulling block can be released. At this time, under the elastic reset action of the spring, the spring will drive the clamping post to slide into the card slot, thereby realizing the rapid connection between the mounting seat and the frame base, so as to quickly install the radar sensor on the passenger car body; through the cooperation of the above structures, the efficiency and convenience of disassembling or installing the radar sensor can be improved.

[0014] 2. In the present invention, the radar sensor can perform positioning monitoring on the obstacles when the passenger car body turns and moves, and feed back the distance and position of the obstacles to the controller and display them on the display screen, so that the staff inside the cab can perform steering operations and try to avoid collisions when the passenger car body turns, improving safety.

[0020] Refer to Figures 1-4 , an inner groove 24 is formed on the inner side wall of the slot 23, and a through hole 25 is formed on the inner wall of the inner groove 24; the installation mechanism 3 includes two springs 31, and the two springs 31 are fixedly connected to the inner walls of the inner groove 24 on both sides of the through hole 25. One end of the spring 31 close to the slot 23 is fixedly connected with a clamping column 32, one side surface of the clamping column 32 away from the slot 23 is fixedly connected with a pull rod 33, and one end of the pull rod 33 away from the clamping column 32 passes through the through hole 25 and is fixedly connected with a pulling block 34. The outer surface of the clamping column 32 is slidably connected with the inner surface of the inner groove 24, and the outer diameter of the clamping column 32 is adapted to the inner diameter of the clamping groove 15; specifically, when installing the radar sensor 22 after maintenance, the pulling block 34 can be pulled first to make the pull rod 33 drive the clamping column 32 to compress the spring 31, so that the clamping column 32 completely slides into the inner groove 24.
