Technical Field

[0001] This application relates to the field of sweeping vehicles, and more specifically, to an unmanned vehicle road sweeping device. Background Technology

[0002] The main function of unmanned vehicles for road cleaning is to install sweeping brushes under the unmanned vehicles. The sweeping brushes contact the ground to clean up the dust on the ground.

[0003] However, autonomous driving cannot function like a human driver. When encountering pedestrians, controlling the sweeping brush to collect items can easily cause inconvenience to pedestrians. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0033] Since traditional manual cleaning is prone to safety hazards when dealing with complex road conditions, this application provides an unmanned vehicle road cleaning and sweeping device.

[0034] To prevent dust from bothering pedestrians, this application discloses an unmanned vehicle road cleaning and sweeping device comprising: a sweeping brush 1, a connecting housing 2, a first drive component 3, a second drive component 4, and a pedestrian detection sensor. The first drive component 3 is a drive motor, used to rotate the sweeping brush 1. The sweeping brush 1 is in contact with the ground. The pedestrian sensor is used to detect pedestrians near the unmanned vehicle. Two pedestrian sensors are provided, one at the front end and the other at the rear end of the unmanned vehicle. The second drive component 4 is one of a robotic arm, a pneumatic cylinder, and a hydraulic cylinder, preferably a hydraulic cylinder for easy installation on the unmanned vehicle. The second drive component 4 is used to move the sweeping brush 1 to the outside and below the unmanned vehicle. The output end of the second drive component 4 is connected to the connecting housing 2. The first drive component 3 is mounted on the connecting housing 2, and its output end is connected to the sweeping brush 1. The sweeping brush 1 uses existing technology, with a rigid portion connected to the motor. When the pedestrian sensor detects a pedestrian passing near the unmanned vehicle, the second drive unit 4 drives the sweeping brush 1 to move below the unmanned vehicle.

[0035] By adopting the above technical solutions, the unmanned vehicle can more accurately avoid pedestrians during cleaning operations, preventing the dust swept by the cleaning brush 1 from soiling pedestrians' clothes and preventing pedestrians from tripping over the cleaning brush 1, thus greatly improving the safety of the unmanned vehicle cleaning process.

[0036] In one embodiment, the second drive unit 4 is connected to the cleaning brush 1 via a high-pressure suction cup, allowing the cleaning brush 1 to be detachably adsorbed by the high-pressure suction cup. The high-pressure suction cup is a high-pressure vacuum suction cup, which facilitates the disassembly and replacement of the cleaning brush 1.

[0037] In another embodiment, the diameter of the cleaning brush 1 is greater than half the width of the unmanned vehicle. Both the cleaning brush 1 and the second drive component 4 are provided in two sets. When both sets of the cleaning brush 1 are located under the unmanned vehicle, the two sets of cleaning brush 1 are positioned opposite each other along the length of the unmanned vehicle. This means that one cleaning brush 1 is located in the front half of the unmanned vehicle, and the other cleaning brush 1 is located in the rear half. This significantly increases the volume and area of ​​the cleaning brush 1 while still allowing it to be neatly stored under the unmanned vehicle.

[0038] In other designs, a dust cover 5 is provided on the second drive component 4, which at least partially covers the cleaning brush 1. This prevents large-scale dust from being released into the air, thus protecting the environment.

[0039] Specifically, a suction pump is installed on the dust cover 5; a filter box 6 is installed on the unmanned vehicle; the suction pump draws dust from the dust cover 5 into the filter box 6. The filter box 6 can filter the dust. In one embodiment, the filter box 6 is a box structure made of spliced ​​filter screens.

[0040] In other designs, the filter box 6 is filled with water, and the suction pump body draws dust into the filter box 6 via a connecting pipe; the connecting pipe is inserted from top to bottom into the filter box 6. Dust-laden air passes through the water and is then expelled, thus effectively filtering out the dust. An exhaust pipe 7 is formed on the filter box 6, located at its upper part. The exhaust pipe 7 is relatively long to prevent water from escaping from the filter box 6 when the unmanned vehicle moves. The filter box 6 is a closed box. Multiple exhaust pipes 7 are installed above the filter box 6, thus utilizing the water filling to enable the filter box 6 to perform its filtering function.

[0041] Specifically, the dust cover 5 has soft pads on its edges. The soft pads are used to protect the dust cover 5 and prevent it from being deformed due to impact with the curb.

[0042] Specifically, the dust cover 5 and the cleaning brush 1 form a movable elastic connection, allowing the dust cover 5 to move closer to and further away from the cleaning brush 1 in a vertical direction. Multiple guide rods 8 are provided on the connecting housing 2, and multiple insertion holes are provided on the dust cover 5, into which the guide rods 8 are inserted. A spring 9 is provided between the upper part of the dust cover 5 and the guide rods 8, allowing the dust cover 5 to move upwards when the ground is raised and downwards when the ground is flat.

[0043] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
