Technical Field

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

[0002] Automotive LiDAR combines a 3D laser scanner with a POS system mounted on a vehicle. Its purpose is to establish a DTM model over a longer and farther range. The purpose of GPS is to allow the vehicle to "know" its position at any moment to facilitate fitting. In any mobile measurement system, the navigation system, as the source of geographic coordinates for point clouds and images, is a key component. An advanced navigation system must include other auxiliary sensors and comprehensive data processing methods to ensure the accuracy of its route even when the GPS signal is lost. The existing LiDAR cleaning nozzle assembly is mounted on the front bumper of the vehicle, and the exterior surface is exposed. When the vehicle is driving, flying stones hit the nozzle exterior surface, causing the internal spray ball cover that is close to the exterior surface to loosen and fall off, causing the nozzle to lose its cleaning function. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides a laser radar cleaning nozzle, which solves the problem that the existing laser radar cleaning nozzle assembly is installed on the front bumper of the vehicle, with the exterior surface exposed. When the vehicle is driving, flying stones hit the exterior surface of the nozzle, causing the internal spray ball sheath close to the exterior surface to loosen and fall off, causing the nozzle to lose its cleaning function.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a laser radar cleaning nozzle comprising a nozzle bracket, a protective sleeve fixedly connected to the top of the nozzle bracket, a water spraying groove formed at one end of the protective sleeve, a support wall fixedly connected to the interior of the protective sleeve, a plurality of delivery nozzles fixedly connected to the side of the protective sleeve, a first nozzle, a second nozzle, and a third nozzle respectively sleeved on the exterior of the plurality of delivery nozzles, and a delivery pipe fixedly connected to the bottom of the nozzle bracket.

[0005] Preferably, holes are respectively provided at both ends of the nozzle bracket, and an anti-crush steel ring is fixedly connected inside.

[0006] Preferably, the top protrusion of the first nozzle has a first connecting port, the top protrusion of the second nozzle has a second connecting port, and the top protrusion of the third nozzle has a third connecting port. The first nozzle, the second nozzle, the third nozzle and the delivery nozzle are connected through the first connecting port, the second connecting port and the third connecting port respectively.

[0007] Preferably, the support wall is supported between the first nozzle, the second nozzle and the third nozzle.

[0008] Preferably, the delivery pipe and the first nozzle, the second nozzle and the third nozzle are interconnected.

[0009] The utility model provides a laser radar cleaning nozzle. Compared with the existing technology, it has the following advantages:

[0010] 1. The laser radar cleaning nozzle is optimized by optimizing the interference surface between the protective cover and the first, second and third nozzles, increasing the interference area, increasing the structural thickness of the appearance surface of the first, second and third nozzles, increasing the strength and reducing the deformation of the appearance surface. The first, second and third nozzles are added to the inside of the protective cover. The internal structural support ribs are arranged on both sides of the first, second and third nozzles inside the protective cover to increase the wall thickness and enhance the overall structural stability of the device. The deformation of the nozzle after being subjected to external force is reduced to avoid flying stones hitting the surface of the protective cover, causing the first, second and third nozzles close to the inside of the protective cover to loosen or fall off, causing the nozzle to lose its cleaning function.

[0011] 2. The laser radar cleaning nozzle is equipped with an anti-crush steel ring. After the screws are tightened according to the required torque, the screws and the nozzle bracket pressing surface will be crushed. The vehicle vibration will cause the screws to loosen. An anti-crush steel ring is added to the mounting hole position. It can be press-fitted on the nozzle bracket body or injection molded with the protective cover body to solve the problems of nozzle body collapse and screw loosening.
