Description

Technical Field

[0001] This utility model relates to the technical field of drones, specifically to an obstacle-crossing and wall-climbing drone. Background Technology

[0002] Currently, wall-climbing robots have moved beyond the laboratory and are replacing manual labor in various industries for tasks performed in extreme environments such as high altitudes and dangerous situations. They overcome the constraints of gravity through technologies such as magnetic adsorption and vacuum adsorption, and integrate intelligent sensing systems, demonstrating their capabilities in fields such as industrial inspection, emergency rescue, and infrastructure maintenance. Wall-climbing robots can be mainly divided into the following categories:

[0003] Category 1: Negative Pressure Adsorption The principle is to create a low-pressure area (partial vacuum) between the robot body and the wall using one or more fans, and then use atmospheric pressure to press it against the wall. The disadvantages are high energy consumption, drastic efficiency drop on rough or porous surfaces, and immediate fall if the seal is broken.

[0004] Category 2: Bionic Adsorption 1. Van der Waals adhesion: The disadvantages are high technical difficulty, easy contamination of the sole material by dust leading to failure, and low load-bearing capacity; 2. Grip and adhere: The disadvantage is that it is completely dependent on the texture of the wall and is ineffective on smooth surfaces (such as glass); 3. Electrostatic adsorption: The disadvantage is that the adhesion is relatively weak and it is sensitive to surface dust and humidity.

[0005] Category 3: Magnetic Adsorption The principle is to use permanent magnets or electromagnets to adhere to the surface of magnetically conductive materials (such as steel). The disadvantage is that its application scenarios are extremely limited, and it can only be used on steel structures such as oil storage tanks, ships, and bridges. Utility Model Content

[0006] To address the aforementioned problem—that existing wall-climbing drones cannot adapt to wall-climbing operations under different conditions—this invention proposes an obstacle-climbing drone, comprising a chassis, an adsorption unit mounted on the upper surface of the chassis to generate an adsorption force perpendicular to the chassis, electrically driven multi-directional wheels mounted on the lower surface of the chassis, and a lifting unit mounted on the front edge of the chassis to generate a lifting force parallel to the chassis; a mounting mechanism is also provided on the side surface of the chassis where the electrically driven multi-directional wheels are mounted.

[0007] A further feature of this invention is that the adsorption unit includes an adsorption frame connected to the chassis, and an installation portion is provided on the adsorption frame, wherein an adsorption impeller unit is installed in the installation portion.

[0008] A further feature of this invention is that the adsorption impeller unit includes adsorption blades, and a drive device is connected to the adsorption blades to drive the adsorption blades to rotate. The adsorption blades are disposed in the mounting part, and the drive device is mounted on the chassis.

[0009] A further feature of this invention is that: four mounting portions are provided, and four mounting portions are also provided for the adsorption impeller unit corresponding to the four mounting portions; the four mounting portions are arranged in a rectangular pattern.

[0010] A further feature of this invention is that the lifting unit includes a lifting frame, the lifting frame is connected to the front edge of the chassis, the lifting frame has an installation opening, and a lifting impeller unit is installed in the installation opening.

[0011] A further feature of this invention is that the lifting impeller unit includes lifting blades, and a second driving device is connected to the lifting blades to drive the lifting blades to rotate. The lifting blades are disposed in the mounting opening. A mounting plate is disposed below the lifting frame, the mounting plate is disposed parallel to the lifting frame, and the mounting plate is fixedly connected to the chassis. The second driving device is mounted on the mounting plate.

[0012] A further feature of this invention is that: a plurality of mounting ports are provided, the plurality of mounting ports are arranged in two rows, and the two rows of mounting ports are symmetrically arranged about the chassis; a plurality of mounting ports are also provided for each of the lifting impeller units.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up the adsorption unit, it can generate an adsorption force perpendicular to the chassis, thereby allowing the drone body to be pressed against the wall. The drone body can move horizontally and vertically on the wall through electric multi-directional wheels, thereby driving other load devices on the drone body to complete the relevant work on the wall.

[0015] 2. By incorporating an elevator unit, a lifting force parallel to the chassis is generated, enabling the drone to ascend and descend in height. Combined with the reverse rotation of the adsorption unit, the drone detaches from the wall and hovers in the air, performing ascent and descent maneuvers. When encountering obstacles, it can collaboratively overcome them and then climb back onto the wall. This significantly solves the problem of existing obstacle-crossing and wall-climbing drones being unable to adapt to different wall conditions, making it more adaptable and enabling obstacle-crossing and wall-climbing processes on walls with varying conditions.

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0021] This utility model proposes an obstacle-crossing and wall-climbing drone, including a chassis 1, which is a square plate. An adsorption unit 2 is installed on the upper surface of the chassis 1 to generate an adsorption force perpendicular to the chassis 1, thereby enabling the chassis 1 to move along the direction of the adsorption force. Four electric multi-directional wheels 11 are installed on the lower surface of the chassis 1. The electric multi-directional wheels 11 are Mecanum wheels to enable them to move freely in multiple directions. Each electric multi-directional wheel 11 is connected to a motor for driving rotation. The motor is fixedly installed on the chassis 1 to drive the electric multi-directional wheel 11 to rotate.

[0022] A lifting unit 3 is installed at the front edge of the chassis 1 to generate a lifting force parallel to the chassis 1. The lifting force is perpendicular to the suction force and the axis of the electric multi-directional walking wheel 11, thereby enabling the chassis 1 to move along the direction of the lifting force.

[0023] Several mounting mechanisms 12 are also welded onto the chassis 1. The mounting mechanism 12 is an ear plate with mounting holes for mounting items required for work.

[0024] The adsorption unit 2 includes an adsorption frame 21, which is fixedly connected to the chassis 1. The adsorption frame 21 has four circular mounting parts 211, which are arranged in a positive direction. An adsorption impeller unit 22 for generating power is installed in the mounting part 211, which is used to generate adsorption force.

[0025] The adsorption impeller unit 22 includes adsorption blades 221, which are disposed in the mounting part 211. A drive device 222 is coaxially connected to the adsorption blades 221 to drive the adsorption blades 221 to rotate. The drive device 222 is a motor and is fixedly mounted on the chassis 1. The drive device 222 drives the adsorption blades 221 to rotate, which can generate adsorption force. By changing the rotation direction of the drive device 222, the direction of the adsorption force can be changed.

[0026] The lifting unit 3 includes a lifting frame 31, which is fixedly connected to the front edge of the chassis 1. The lifting frame 31 has eight mounting ports 311, which are arranged in two rows with four ports in each row. The two rows of mounting ports 311 are symmetrical about the chassis 1.

[0027] A lifting impeller unit 32 is installed inside the mounting port 311. The lifting impeller unit 32 includes lifting blades 321, and a second drive device 322 is connected to the lifting blades 321 to drive the lifting blades 321 to rotate. The second drive device 322 is also a motor. A mounting plate 33 is also provided below the lifting frame 31. The mounting plate 33 is parallel to the lifting frame 31 and perpendicular to the chassis 1. The mounting plate 33 is fixedly connected to the chassis 1, and the drive device is fixedly connected to the mounting plate 33.

[0028] The second drive device 322 drives the lifting blade 321 to rotate, which generates lifting force, thereby enabling the UAV body to lift and take off.

[0029] In summary, by setting up the adsorption unit 2, it can generate an adsorption force perpendicular to the chassis 1, thereby enabling the drone body to press firmly against the wall. The drone body can move horizontally and vertically on the wall through the electric multi-directional walking wheels 11, thereby driving other load devices on the body to complete the relevant work on the wall.

[0030] By setting up the elevator unit 3, a lifting force parallel to the chassis 1 can be generated, enabling the drone to rise and fall in height. Combined with the reverse rotation of the adsorption unit 2, the drone detaches from the wall and hovers in the air, performing ascent and descent maneuvers. When encountering obstacles, it can collaboratively overcome them and then climb back onto the wall. This greatly solves the problem of existing obstacle-crossing and wall-climbing drones being unable to adapt to different wall conditions, making it more adaptable and enabling obstacle-crossing and climbing on walls with varying conditions.

In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
