Description

Technical Field

[0001] The utility model relates to the technical field of intelligent driving, and in particular to an intelligent driving distance measuring device provided with an auxiliary structure. Background Art

[0002] Smart cars need to use sensors during parking and stopping, which generally include: laser, ultrasonic, radar, infrared and machine vision image ranging, etc. Laser ranging has the advantages of good stability and high ranging accuracy. However, due to its high price, its market application development is limited. Ultrasonic ranging has higher accuracy. However, when measuring long distances, the received echo is weak and slow, resulting in inaccurate measurement information. Therefore, ultrasonic ranging is generally used in short-distance environments such as reversing systems. Radar ranging measures distance by receiving electromagnetic waves reflected from objects. Radar transmission will not be affected by complex weather, and even in bad weather, it can ensure that the results are still accurate. Moreover, compared with lasers, the cost is relatively low, but it is easily interfered with by signals from other radars or other communication facilities;

[0003] Machine vision ranging uses camera sensors to capture surrounding image information and calculate the distance to obstacles by establishing a three-dimensional relationship model between the image information and space. Machine vision-based distance measurement technology is a key technology in the research of intelligent vehicle driver assistance systems based on environmental perception. It has the following advantages: wide range, light weight, wide range, and low cost. Although it is susceptible to environmental interference, its combination with other sensors for distance measurement is currently one of the most promising research directions.

[0004] Chinese Patent Authorization Announcement No. CN220625327U discloses a distance measuring device for intelligent driving, including a shell, a first spring fixedly connected to the rear side of the bottom of the inner cavity of the shell, a cross plate fixedly connected to the top of the first spring, a movable block fixedly connected to the central axis of the front bottom of the cross plate, movable rods movably connected to both sides of the bottom of the movable block, a sliding sleeve movably connected to one side of the movable rod, a second spring fixedly connected to one side of the sliding sleeve, and a second spring fixedly connected to the shell on one side. The utility model has an anti-seismic effect by providing the first spring, the cross plate, the movable block, the movable rod, the sliding sleeve and the second spring. By providing a water tank, an electric cylinder and a brush plate, it is convenient to clean the detection end of the rangefinder, so that the detection is accurate. By providing the sliding rod, the operation of the sliding sleeve is stabilized and the sliding sleeve is balanced and supported. By providing the damper, a damping effect is achieved to avoid continuous shaking.

[0005] The above-mentioned existing technical solution has the following shortcomings: this technical solution is to clean the detection end of the rangefinder by driving the brush plate through the electric cylinder when the car has been used for a period of time and is not working. This technical solution is aimed at the situation when the vehicle is not in operation. If mud adheres to the surface or it is raining, it will directly affect the ranging effect of driving the car. At the same time, when the existing rangefinder is operated at night, although there is illumination from the car headlights at night, it is easy to be affected by the shadows created by the objects illuminated by the light, which is not conducive to the ranging of the rangefinder. Therefore, it is necessary to design an intelligent driving ranging device with an auxiliary structure to solve the above problems. Utility Model Content
