Description

Technical Field

[0001] The present invention belongs to the technical field related to smart home devices, and particularly relates to an intelligent floor sweeping robot. Background Art

[0002] In the field of modern household cleaning, floor sweeping robots, as intelligent cleaning devices, are increasingly favored by consumers due to their advantages such as automatic floor cleaning and labor saving. However, during actual use, when floor sweeping robots operate in complex household environments, they inevitably collide with various obstacles, which brings many problems to the normal use and lifespan of the floor sweeping robots;

[0003] Most traditional anti-collision devices for floor sweeping robots are of fixed structures, with fixed buffering performance and unable to be flexibly adjusted according to actual use scenarios and different collision situations. For example, in some areas where furniture is placed densely, floor sweeping robots frequently collide with obstacles. Fixed anti-collision devices are difficult to effectively buffer large impact forces, easily causing wear on the robot's shell, loosening or even damage to components, affecting its normal operation and lifespan; while in some empty areas, overly "rigid" anti-collision devices may cause the floor sweeping robot to change its operation route even when slightly touched, reducing the cleaning efficiency. In addition, once traditional anti-collision devices are damaged, they often require complex disassembly and replacement processes, not only increasing the maintenance cost and difficulty for users, but also possibly affecting the normal use of the floor sweeping robot due to untimely repair. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent floor sweeping robot to solve the problems raised in the above background art, that is, floor sweeping robots in modern households are favored, but they are prone to collide with obstacles when operating in complex environments. Traditional anti-collision devices are fixed, with non-adjustable buffering performance. They cannot effectively buffer large impact forces in areas with dense furniture, resulting in damage to the robot and affecting its lifespan.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The present invention provides Figure 1-7An intelligent floor-sweeping robot as shown includes a floor-sweeping robot body 2 and an obstacle detector 3 arranged at the front side of the center of the top end of the floor-sweeping robot body 2. The obstacle detector 3 is close to the front end of the floor-sweeping robot body 2. A plurality of infrared detection windows 4 are equidistantly arranged inside the circular outer wall of the obstacle detector 3. The floor-sweeping robot body 2 senses the surrounding environment through the obstacle detector 3 arranged at the front side of the center of the top end of the floor-sweeping robot body 2. The obstacle detector 3 is close to the front end, and the plurality of infrared detection windows 4 equidistantly distributed inside its circular outer wall can emit and receive infrared signals. When the infrared rays are reflected back by an obstacle, the infrared detection window 4 receives the reflected signal, so that the floor-sweeping robot body 2 obtains information about the surrounding obstacles, realizes the detection of the surrounding environment, plans the cleaning path, and avoids colliding with obstacles. Inside the center of the top end of the floor-sweeping robot body 2 and its rear side, there is a cleaning bin 7. A bin cover 8 is inserted into the inside of the opening of the cleaning bin 7, and the bin cover 8 is fixed in the opening of the cleaning bin 7 by a buckle. A plurality of heat dissipation holes 9 are arranged inside the rear side of the center of the bin cover 8. During the cleaning process, the garbage is sucked into the cleaning bin 7 inside the center of the top end of the floor-sweeping robot body 2 and its rear side through the garbage suction slot 20. The bin cover 8 inserted into the inside of the opening of the cleaning bin 7 is fixed by a buckle, which is convenient for regularly opening the bin cover 8 to clean the garbage. The heat dissipation holes 9 help to dissipate the heat generated by the floor-sweeping robot body 2 during operation, ensuring the stable operation of the internal electronic components and the power system in a suitable temperature environment. A display screen 6 is arranged on the left side of the center of the top end of the floor-sweeping robot body 2, and a manual start / stop button 1 is arranged on the right side of the center of the top end of the floor-sweeping robot body 2. The display screen 6 can display the working status, power information, etc. of the device, facilitating the user to understand the operation of the device. The manual start / stop button 1 on the right side provides a convenient way for the user to manually control the start and stop of the floor-sweeping robot.

[0026] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, inside the center of the bottom end of the floor sweeping robot body 2, there is a garbage suction slot 20. Inside the garbage suction slot 20, there is a main cleaning roller 21. On the outer wall of the main cleaning roller 21, multiple groups of main brush hairs 22 are equidistantly arranged. The floor sweeping robot body 2 can drive the main cleaning roller 21 to rotate uniformly through the internal electric output shaft. As the roller rotates, the main brush hairs 22 continuously sweep across the ground, concentrating the dust, debris, etc. on the ground towards the garbage suction slot 20, facilitating subsequent suction into the cleaning bin 7. At the front side of the center of the garbage suction slot 20, there is a front wheel hole 11. The front wheel hole 11 is close to the front end of the floor sweeping robot body 2. Inside the center of the steering drive wheel seat 12, there is a reserved wheel groove. Inside the wheel groove, there is a drive front wheel 13. The bottom end of the drive front wheel 13 is exposed outside the bottom wall of the floor sweeping robot body 2. The drive front wheel 13 is driven by the power system inside the floor sweeping robot body 2 and is responsible for providing the power for forward movement and steering, enabling the floor sweeping robot to perform cleaning operations in different areas according to the preset path. On the left rear side and the right rear side of the front wheel hole 11, there are shaft holes 10. Inside both shaft holes 10, there are side sweeping rotating shafts 14. On the circular outer wall of the bottom end of the side sweeping rotating shaft 14, multiple groups of side sweeping brush hairs 15 are equidistantly arranged. The side sweeping rotating shaft 14 can drive the multiple groups of side sweeping brush hairs 15 on its outer wall to rotate. The side sweeping rotating shaft 14 driving the side sweeping brush hairs 15 to rotate can sweep the garbage around the floor sweeping robot body 2 into the working range of the main cleaning roller 21, expanding the cleaning range and improving the cleaning efficiency. On the left rear side and the right rear side of the garbage suction slot 20, there are rear wheel holes 16. Inside both rear wheel holes 16, there is a rear drive wheel 17 connected by a rotating shaft, and the bottom outer wall of the rear drive wheel 17 is on the same horizontal plane as the bottom outer wall of the drive front wheel 13. The rear drive wheel 17 plays a role in stably supporting the floor sweeping robot body 2 and works in coordination with the drive front wheel 13 to ensure the smoothness of the floor sweeping robot during walking and ensure the smooth progress of the cleaning work. Between the rear sides of the two rear wheel holes 16, there is a support plate 18. The support plate 18 is fixed to the bottom end of the floor sweeping robot body 2. At the bottom end of the support plate 18, there is a mop 19. The mop 19 is fixedly connected to the support plate 18 through Velcro. During the walking of the floor sweeping robot, the mop 19 wipes the ground to achieve further cleaning of the ground. The connection method of Velcro facilitates the disassembly and cleaning of the mop 19.

[0027] As Figure 1 , Figure 6 and Figure 7As shown, adjustable anti-collision devices 5 are provided on the arc-shaped outer walls at both the front and rear ends of the floor-sweeping robot body 2. The adjustable anti-collision device 5 on the front arc-shaped outer wall of the floor-sweeping robot body 2 includes an adhesive patch 23, a long strip-shaped flat buffer airbag 24, and a pneumatic pressure regulating nozzle 25. The adhesive patch 23 is provided on the rear outer wall of the long strip-shaped flat buffer airbag 24, and the long strip-shaped flat buffer airbag 24 is adhered to the front arc-shaped outer wall of the floor-sweeping robot body 2 through the adhesive patch 23. The pneumatic pressure regulating nozzle 25 is provided at the right rear end of the long strip-shaped flat buffer airbag 24. Both the long strip-shaped flat buffer airbag 24 and the pneumatic pressure regulating nozzle 25 are made of elastic soft rubber, and the elastic coefficient of the long strip-shaped flat buffer airbag 24 is greater than that of the pneumatic pressure regulating nozzle 25. During the operation of the floor-sweeping robot, when encountering an obstacle, the first-hit long strip-shaped flat buffer airbag 24 will be impacted first. Due to its large elastic coefficient, it can generate a large deformation to absorb the impact energy, thereby buffering the impact force on the floor-sweeping robot body 2 and reducing the risk of damage to the robot caused by the collision.

[0028] As Figure 1 , Figure 6 and Figure 7 shown, the adjustable anti-collision device 5 further includes a connection hole 26 and a conical self-shrinking rubber sleeve 27. The connection hole 26 is provided inside the right rear end of the long strip-shaped flat buffer airbag 24, and the pneumatic pressure regulating nozzle 25 is communicated with the inside of the long strip-shaped flat buffer airbag 24 through the connection hole 26. The conical self-shrinking rubber sleeve 27 is provided inside the pneumatic pressure regulating nozzle 25, and the tip direction of the conical self-shrinking rubber sleeve 27 faces the connection hole 26. A through hole is provided inside the center of the conical self-shrinking rubber sleeve 27. The through hole can be in a shrunk and closed state due to the material shrinkage characteristic of the conical self-shrinking rubber sleeve 27. Under normal conditions, the conical self-shrinking rubber sleeve 27 keeps the through hole in a shrunk and closed state by virtue of the material shrinkage characteristic to maintain the air pressure stability in the airbag. If it is necessary to adjust the buffering effect, the through hole inside the conical self-shrinking rubber sleeve 27 can be forcibly opened by inserting a syringe. When inflating by inserting the syringe, the gas enters the long strip-shaped flat buffer airbag 24, increasing its degree of expansion, thereby improving the buffering ability. If deflating through the syringe, the degree of expansion of the airbag decreases, and the buffering ability changes accordingly, so as to flexibly adjust the buffering effect of the anti-collision device.

[0029] As Figure 1 , Figure 6 and Figure 7As shown, the adhesive sheet 23 can be directly torn off from the outer wall of the floor sweeping robot body 2. This feature enables the long strip-shaped flat buffer airbag 24 to be conveniently pasted on the arc-shaped outer wall at the front end of the floor sweeping robot body 2. When the anti-collision device is worn or damaged, it can be quickly torn off from the body and a new device can be replaced, greatly improving the convenience and efficiency of maintenance. The length of the long strip-shaped flat buffer airbag 24 is two-fifths of the circumference of the floor sweeping robot body 2. The top and bottom edges at the front end of the long strip-shaped flat buffer airbag 24 are both treated with arc surfaces. The through hole inside the conical self-shrinking rubber sleeve 27 can be forcibly opened by inserting a syringe. The length of the long strip-shaped flat buffer airbag 24 is designed to be two-fifths of the circumference of the floor sweeping robot body 2. Such a length can ensure effective protection for the front end of the robot while not being too long to affect the normal operation of the robot or cause space obstruction. In addition, the top and bottom edges at the front end of the long strip-shaped flat buffer airbag 24 are both treated with arc surfaces. This design can reduce the stress concentration during collision, making the impact force more evenly distributed on the airbag and further enhancing the buffer effect and protection function.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
