Description

Technical Field

[0001] The utility model relates to the technical field of laser radars, in particular to a laser radar shield. Background Art

[0002] LiDAR is a radar system that uses laser beams to detect a target's position, velocity, and other characteristic quantities. It works by transmitting a detection signal (a laser beam) toward the target, then comparing the received signal reflected from the target (the target echo) with the transmitted signal. After appropriate processing, relevant information about the target can be obtained.

[0003] When using a LiDAR, a protective shield is required to ensure its integrity. Existing LiDAR shields use a simple cover structure that is difficult to remove after installation. When the shield is damaged, it cannot be quickly removed and replaced, which is time-consuming and labor-intensive. Furthermore, after prolonged use, a large amount of dust will adhere to the surface of the shield, affecting the normal operation of the LiDAR. Due to its simple structure, the shield requires cleaning with a cleaning cloth or the like. Without a cleaning cloth, the cleaning of the shield is affected, and the LiDAR cannot be restored to normal operation immediately. Utility Model Content

[0019] When using the laser radar, the radar body 1 is installed in a suitable place, the cable is connected using the connector 4, and the shield structure 3 is installed on the radar body 1 before use. When in use, the sensing head 2 emits laser and receives feedback, thereby achieving the purpose of laser sensing. In this process, the shield structure 3 plays a protective role and ensures the normal use of the laser radar.

[0020] Through the above implementation scheme, the shield structure 3 includes a fixed cover 301, a slide groove 304, a protective component 305 and a cleaning component 306. The slide groove 304 is opened on the fixed cover 301, and the fixed cover 301 is installed on the radar body 1. The fixed cover 301 is provided with a through hole connected to the slide groove 304. The protective component 305 is installed in the slide groove 304 on the fixed cover 301, and the protective component 305 passes through the through hole. The cleaning component 306 is fixed to the fixed cover 301. The shield structure 3 also includes a mounting plate 302, a mounting bolt 303 and a threaded hole 307. The mounting plate 302 is fixed on the fixed cover 301, the mounting bolt 303 passes through the mounting plate 302, and the mounting The end of the mounting bolt 303 is connected to the screw groove on the radar body 1. The fixed cover 301 is fixed to the radar body 1 through the mounting plate 302 and the mounting bolt 303. The threaded hole 307 is set on the fixed cover 301. The protective assembly 305 includes a movable frame 3051, a transparent glass 3052, a limiting plate 3053, a connecting bolt 3054 and an operating piece 3055. The transparent glass 3052 is fixed to the movable frame 3051, and the movable frame 3051 is installed in the slide groove 304. The limiting plate 3053 is fixed to the end of the movable frame 3051. The connecting bolt 3054 passes through the limiting plate 3053, and the end of the connecting bolt 3054 is connected to the threaded hole 307. The operating piece 3055 is fixed on the limit plate 3053. The cleaning assembly 306 includes a fixing strip 3061, a wiping strip 3062, a mounting block 3063, a circular hole 3064 and a fixing screw 3065. The fixing strip 3061 is fixedly connected to the wiping strip 3062. The circular hole 3064 is opened on the mounting block 3063, and the mounting block 3063 is set at the end of the fixing strip 3061. The end of the fixing screw 3065 passes through the circular hole 3064 and is connected to the fixed cover 301. Through the set shield structure 3, when the laser radar is effectively protected, the fixed cover 301 can also be quickly removed from the radar body 1, which is convenient for replacing the shield structure 3 and protecting Component 305 is set in the slide groove 304 and can be disassembled and replaced separately when needed, which reduces the replacement cost. After replacement, the connecting bolt 3054 on the limit plate 3053 can be used to ensure the stability of the use of the protective component 305. Using the cleaning component 306, when dust adheres to the transparent glass 3052, the protective component 305 can also be moved to make the transparent glass 3052 and the wiping strip 3062 in the cleaning component 306 move relative to each other, which can effectively wipe and clean the transparent glass 3052. There is no need to prepare a wiping cloth to complete the cleaning work. The cleaning component 306 is installed with a fixing screw 3065, which is easy to disassemble and replace and has high flexibility in use.

[0021] When assembling the shield structure 3, fit the fixing strip 3061 in the cleaning assembly 306 onto the fixing cover 301, set the fixing screw 3065 in the circular hole 3064, and then install it to the mounting block 3063. At this time, the entire cleaning assembly 306 is installed, and the wiping strip 3062 is set on the fixing strip 3061. Insert the movable frame 3051 with the transparent glass 3052 into the slide groove 304 so that the limit plate 3053 abuts the fixing cover 301, and use the connecting bolt 3054 to cooperate with the threaded hole 307 to fix the limit plate 3053, thereby completing the installation of the protection assembly 305. After the shield structure 3 is assembled, set the shield structure 3 on the radar body 1 and fix it with the mounting bolt 303 on the mounting plate 302, thereby completing the installation of the entire shield structure 3. During use, the fixed cover 301 cooperates with the protective component 305 to play a protective role, and the transparent glass 3052 will not affect the normal operation of the sensing head 2. After long-term use, a large amount of dust adheres to the transparent glass 3052 and needs to be cleaned. At this time, the connecting bolts 3054 can be loosened, and the movable frame 3051 can be pulled by the operating piece 3055. The movable frame 3051 moves with the transparent glass 3052. At the same time, the wiping strip 3062 moves relative to the transparent glass 3052, thereby achieving the effect of wiping and cleaning. This can be repeated several times to complete the wiping work of the transparent glass 3052, and then the protective component 305 can be fixed and continued to be used. If the protective component 305 is damaged, it can be quickly disassembled and replaced without replacing the entire protective cover structure 3. It has a simple structure and is easy to operate.
