Wall-climbing vehicle and bottom cover of such vehicle

A wall-climbing vehicle controllable by a remote control over a vertical wall, the wall-climbing vehicle, comprising:

• a car body having a bottom portion;
• a bottom cover configured along the bottom portion, the bottom cover includes a middle portion and a peripheral portion;
• the bottom cover is disposed along the bottom portion such that a gap between the vertical wall and the bottom portion of the wall-climbing vehicle is configured to avoid obstacles along the vertical wall, when the wall-climbing vehicle is driven over the vertical wall;
• the middle portion includes an air intake area defining a cut-out;
• the air intake area enables symmetrical weight balance, the air intake area configured to accommodate a circular air intake arrangement, wherein
• the circular air intake arrangement includes a circular configuration to create a large opening along the air intake area to increase an air suction volume along the air intake area;
• the circular air intake arrangement includes a sealing ring and a sealing cover;
• the sealing ring is coupled to a bottom portion of the circular air intake arrangement and the sealing ring when assembled to the bottom cover, is located in the cut-out of the middle portion of the bottom cover;
• the peripheral portion of the bottom cover includes a plurality of bumps and a plurality of dots arranged underside of the bottom cover;
• the circular air intake arrangement is accommodated along the air intake area via the sealing ring and the sealing cover of the wall-climbing vehicle;
• a plurality of sealing cloth strips configured along sides of the bottom portion to form a closed area in the wall-climbing vehicle, wherein the closed area is continuously evacuated by the circular air intake arrangement to form a negative pressure;
• the plurality of bumps configured along the bottom cover and adjacent to the air intake area, the plurality of bumps configured to increase air suction and balance the negative pressure below the bottom cover to facilitate the wall-climbing vehicle to move over the vertical wall;
• the plurality of dots configured along the bottom cover and adjacent to the air intake area, the plurality of dots and the plurality of bumps alternatingly aligned adjacent to each other, the plurality of dots configured to enable air flow separation to reduce the airflow into the air intake area to facilitate balancing of the wall-climbing vehicle over the vertical wall.
