Description

Technical Field

[0001] The present invention relates to the technical field of driverless vehicles, and in particular to an driverless vehicle suitable for unstructured roads. Background Art

[0002] Unmanned vehicles traveling on unstructured roads face more severe environmental challenges than vehicles on ordinary roads. Self-cleaning technology is essential to ensure the normal operation and stable performance of vehicles. Unstructured roads are often dusty and muddy. During the driving process of the vehicle, a large amount of dirt is easily attached to the body and sensor surface. For example, in mining areas and field operation areas, flying dust will quickly cover the surface of the vehicle, especially the sensors. Once blocked, the accuracy and reliability of sensing equipment such as lidar and cameras will be greatly reduced, seriously affecting the vehicle's ability to perceive the surrounding environment, thereby interfering with the vehicle's decision-making and driving safety.

[0003] Existing vehicle self-cleaning technologies are mostly used on ordinary urban road vehicles, mainly based on simple water spray wiper systems. This method has limited cleaning effect on thick and sticky dirt on unstructured roads. Although some vehicles have adopted hydrophobic coating technology to reduce dirt adhesion, the coating is not durable enough during long-term driving on complex road conditions, and it is still difficult to effectively remove stubborn stains that have already adhered.

[0033] The following is a detailed description of the working principle of this driverless vehicle suitable for unstructured roads.

[0034] like Figure 1-8 As shown, when the present invention is needed, first fill the water tank 71 with water and then install it back, then open the sealing cover plate 142 and pour the lubricating oil into the sealing cover plate 142, and then reset the sealing cover plate 142 for use. When used in a desert or muddy road environment, a lot of sand and dust will adhere to the surface of the unmanned vehicle body 1, affecting the normal use of the signal receiving module 5. At that time, the user needs to remotely control the starting motor 92. When the motor 92 is started, it will drive the driving tooth 93 to rotate. The rotation of the driving tooth 93 will cause the gear ring 81 meshing with it to rotate. The rotation of the gear ring 81 will drive the first gear 82 to rotate. When the first gear 82 rotates, it will drive the second gear 83 to rotate.

When the cam 122 rotates, the slider 131 will follow the groove of the cam 122 to swing. When the slider 131 swings, it will cause the slide bar 132 to push the impact block 133 to quickly impact the unmanned vehicle body 1. When the unmanned vehicle When the vehicle body 1 is hit, the dust and sand on its surface will fall off by themselves due to the vibration. When the slide bar 132 reciprocates, the oil storage chamber 141 will apply the lubricating oil inside to the surface of the slide bar 132, so as to reduce its wear and improve the sliding effect. The two sets of cams 122 are set in different directions, so as to achieve the effect of alternating impact so that the unmanned vehicle body 1 can be effectively cleaned. When the surface of the unmanned vehicle body 1 is overheated, the built-in water pump of the unmanned vehicle body 1 is first started to pump the water inside the water tank 71 to the atomizing nozzle 72 and then spray it to the surrounding area after being atomized by the atomizing nozzle 72 for heat dissipation. The unmanned vehicle body 1 also has the function of forest fire detection. It can provide a fire barrier for the unmanned vehicle body 1 through the continuous spraying of water by the atomizing nozzle 72, so that the unmanned vehicle body 1 can detect and guide trapped persons at the fire scene. When the second gear 83 rotates, it will drive the cleaning roller brush 100 to rotate. The rotation of the cleaning roller brush 100 will clean the cam 122 so that it will not be attached by dust.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
