[0016] A method for using a front-collision floating structure of a sweeping robot: S1: Install the front impact floating shell on the front side of the robot shell, and ensure that all sliding connections and fixed connections are correctly installed, connect the horizontal threaded sleeve and the horizontal threaded rod, and ensure that they can slide and rotate smoothly. Install the worm gear and worm in place, and connect the first motor, install all parts of the No. 1 floating part and the No. 2 floating part, and ensure that each part can slide and rotate normally, install all parts of the air supply part, and ensure that the connection between the air pump, the air extraction pipe and the filter is unobstructed; S2: Make sure the robot body is powered on and all motors and sensors are properly connected to the control board. Turn on the robot's power switch and make sure all systems are in standby mode. Start the robot through the remote control or mobile phone application. After the robot starts, the lidar sensor starts scanning the environment, building a map and planning the cleaning path. S3: When the robot encounters an uneven ground or an obstacle, the lifting floating plate will float up and down in the vertical direction. The sliding connection between the No. 1 floating axis and the No. 2 floating axis allows the lifting floating plate to move in the vertical direction. The floating spring provides elasticity and reset ability, so that the lifting floating plate can absorb the impact force when encountering an obstacle and return to its initial position after the obstacle disappears. S4: Driven by the second motor, the lifting bidirectional threaded rod rotates, so that the upper and lower lifting threaded sleeves move up and down on the lifting bidirectional threaded rod respectively, ensuring that the movement trajectory of the lifting threaded sleeve is straight to avoid offset and jamming. Connect the lifting threaded sleeve and the lifting mounting plate so that the lifting mounting plate moves up and down in the vertical direction. Adjust the angle of the rotating frame by extending and retracting the electric push rod, thereby changing the position and posture of the rubber suction head. The rubber suction head can be adsorbed on the smooth surface through the gas provided by the air supply part, helping the robot to better adhere and clean. Start the air pump, draw air from the outside through the exhaust pipe, and enter the annular air pipe after being filtered by the filter. The annular air pipe is interconnected with multiple air supply cavities to evenly distribute the gas to each air supply cavity. The air supply cavity transports the gas to the rubber suction head through the air supply pipe, so that the rubber suction head generates suction to help the robot adhere to the smooth surface.

[0017] Through the above steps, the efficient operation and long-term use of the front-collision floating structure of the sweeping robot can be ensured. This design not only improves the robot's anti-collision performance and adaptability, but also enhances its cleaning ability in complex terrain.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. When the robot of the present invention encounters an uneven ground or an obstacle, the lifting floating plate will float up and down in the vertical direction. The sliding connection between the No. 1 floating axis and the No. 2 floating axis allows the lifting floating plate to move in the vertical direction. The floating spring provides elasticity and reset ability, so that the lifting floating plate can absorb the impact force when encountering an obstacle and return to its original position after the obstacle disappears.

[0019] 2. The present invention drives the lifting bidirectional threaded rod to rotate through the second motor, so that the upper and lower lifting threaded sleeves move upward and downward on the lifting bidirectional threaded rod respectively, ensuring that the movement trajectory of the lifting threaded sleeve is linear to avoid offset and jamming. The lifting threaded sleeve and the lifting mounting plate are connected so that the lifting mounting plate moves up and down in the vertical direction. The angle of the rotating frame is adjusted by the extension and contraction of the electric push rod, thereby changing the position and posture of the rubber suction head. The rubber suction head can be adsorbed on a smooth surface through the gas provided by the gas supply part, helping the robot to better adhere and clean.

[0020] 3. In the present invention, larger particles and impurities are blocked out through multiple No. 1 filter holes on the No. 1 filter plate, and the air then passes through multiple No. 2 filter holes on multiple No. 2 filter plates, and smaller particles and impurities are further filtered. The position of the No. 2 filter plate can be manually adjusted through the handle so that it can be adjusted according to the environment and needs to ensure the filtering effect. The multi-stage filtration design effectively removes dust and impurities in the air, protects the air pump and extends its service life. The design of the filter element ensures the uniform distribution of gas and the stable suction of the rubber suction head, thereby improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Furthermore, the front-collision floating mechanism 200 includes a front-collision floating shell 201, a horizontal telescopic part is slidably connected between the front-collision floating shell 201 and the front side of the robot shell 101, a No. 1 floating part 208 is slidably connected to the top of the front-collision floating shell 201, and a plurality of No. 2 floating parts 209 are arranged in a circular array on the circumferential surface of the front-collision floating shell 201 away from the robot shell 101, and one end of the plurality of No. 2 floating parts 209 extends into the interior of the front-collision floating shell 201 and is slidably connected thereto.

[0025] The front-impact floating shell 201 is installed on the front side of the robot shell 101, and is slidably connected to the robot shell 101, and can be extended and retracted in the horizontal direction. The horizontal telescopic member connects the front-impact floating shell 201 and the robot shell 101, allowing the front-impact floating shell 201 to be extended and retracted in the horizontal direction to adapt to different collision situations. The No. 1 floating member 208 is slidably connected to the top of the front-impact floating shell 201, which can provide additional floating capacity to help the robot better adapt to obstacles of different heights. Multiple No. 2 floating members are arranged in a circular array on the circumferential surface of the front-impact floating shell 201, and one end extends to the interior of the front-impact floating shell 201 and is slidably connected thereto. These floating members can further improve the flexibility and adaptability of the front-impact floating shell 201.

[0026] Furthermore, the horizontal telescopic member includes a plurality of horizontal threaded sleeves 202 arranged in a circular array on one side of the inner wall of the front impact floating shell 201. The plurality of horizontal threaded sleeves 202 extend away from one end of the front impact floating shell 201 to the inside of the robot shell 101 and are slidably connected thereto.

When the multiple worm wheels 205 rotate, the multiple horizontal threaded rods 203 are driven to rotate. The rotation of the horizontal threaded rods 203 causes the horizontal threaded sleeve 202 to expand and contract in the horizontal direction, thereby realizing the horizontal movement of the front impact floating shell 201. Furthermore, the No. 1 floating member 208 includes a lifting floating plate 208a slidably arranged on the top of the front impact floating shell 201, and the bottom of the lifting floating plate 208a is fixedly connected with multiple No. 1 floating shafts 208b in a circular array, and the surfaces of the multiple No. 1 floating shafts 208b are all slidably connected with fixed sleeves 208c, and the multiple fixed sleeves 208c are fixedly arranged on the top of the front impact floating shell 201 in a circular array, and the interiors of the multiple fixed sleeves 208c are all slidably connected with No. 2 floating shafts 208d, and the tops of the multiple No. 2 floating shafts 208d are slidably connected with the bottoms of the multiple No. 1 floating shafts 208b, and a floating spring 208e is fixedly connected between the multiple fixed sleeves 208c and the multiple No. 2 floating shafts 208d.

[0030] When the robot encounters uneven ground or obstacles, the lifting floating plate 208a will float up and down in the vertical direction. The sliding connection between the No. 1 floating axis 208b and the No. 2 floating axis 208d allows the lifting floating plate 208a to move in the vertical direction. The floating spring 208e provides elasticity and reset ability, so that the lifting floating plate 208a can absorb the impact force when encountering an obstacle and return to its original position after the obstacle disappears.

The lifting threaded sleeve 209d and the lifting mounting plate 209g are connected so that the lifting mounting plate 209g moves up and down in the vertical direction. The angle of the rotating frame 209i is adjusted by the extension and contraction of the electric push rod 209k, thereby changing the position and posture of the rubber suction head 209l. Through the gas provided by the gas supply part 210, the rubber suction head 209l can be adsorbed on a smooth surface, helping the robot to better adhere and clean.

The multi-stage filtration design effectively removes dust and impurities in the air, protects the air pump 210d, and extends its service life. The design of the filter element 211 ensures the uniform distribution of gas and the stable suction of the rubber suction head 209l, thereby improving the cleaning effect.

[0039] A method for using a front-collision floating structure of a sweeping robot: S1: Install the front impact floating shell 201 on the front side of the robot housing 101, and ensure that all sliding connections and fixed connections are properly installed, connect the horizontal threaded sleeve 202 and the horizontal threaded rod 203, and ensure that they can slide and rotate smoothly. Install the worm gear 205 and the worm 206 in place, and connect the first motor 207, install all parts of the No. 1 floating part 208 and the No. 2 floating part 209, and ensure that each part can slide and rotate normally, install all parts of the air supply part 210, and ensure that the connection between the air pump 210d, the exhaust pipe 210e and the filter 211 is unobstructed; S2: Ensure that the power of the robot body 100 is turned on and all motors and sensors are correctly connected to the control board, turn on the power switch of the robot, ensure that all systems are in standby mode, and start the sweeping robot through the remote control or mobile phone application. After the robot is started, the laser radar sensor 102 starts to scan the environment, build a map and plan a cleaning path; S3: When the robot encounters an uneven ground or an obstacle, the lifting floating plate 208a will float up and down in the vertical direction. The sliding connection between the first floating shaft 208b and the second floating shaft 208d allows the lifting floating plate 208a to move in the vertical direction. The floating spring 208e provides elasticity and reset ability, so that the lifting floating plate 208a can absorb the impact force when encountering an obstacle and return to the initial position after the obstacle disappears. S4: Driven by the second motor 209b, the lifting bidirectional threaded rod 209a rotates, so that the upper and lower lifting threaded sleeves 209d move upward and downward on the lifting bidirectional threaded rod 209a respectively, ensuring that the movement trajectory of the lifting threaded sleeve 209d is linear to avoid deviation and jamming. The lifting threaded sleeve 209d and the lifting mounting plate 209g are connected so that the lifting mounting plate 209g can move up and down in the vertical direction. The angle of the rotating frame 209i is adjusted by extending and retracting the electric push rod 209k, thereby changing the position and posture of the rubber suction head 209l. The rubber suction head 209l can be adsorbed on the smooth surface through the gas provided by the air supply part 210, which helps the robot to adhere and clean better. The air pump 210d is started, and air is drawn from the outside through the exhaust pipe 210e. After being filtered by the filter element 211, it enters the annular air pipe 210c. The annular air pipe 210c is interconnected with multiple air supply cavities 210b, and the gas is evenly distributed to each air supply cavity 210b. The air supply cavity 210b transports the gas to the rubber suction head 209l through the air supply pipe 210a, so that the rubber suction head 209l generates suction, which helps the robot to adhere to the smooth surface.

[0040] Through the above steps, the efficient operation and long-term use of the front-collision floating structure of the sweeping robot can be ensured. This design not only improves the robot's anti-collision performance and adaptability, but also enhances its cleaning ability in complex terrain.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
