Description

Technical Field

[0001] This utility model relates to the field of sweeping robot technology, and in particular to a tracked obstacle-crossing sweeping component and its sweeping robot. Background Technology

[0002] A robotic vacuum cleaner, also known as an automatic cleaning machine, smart vacuum cleaner, or robotic vacuum cleaner, is a household appliance that uses artificial intelligence to automatically clean floors in a room. Robotic vacuum cleaners typically use various built-in sensors to perceive their surroundings, such as collision sensors that allow them to change direction when they bump into furniture or walls; infrared sensors that detect obstacles ahead to prevent them from falling down stairs or causing other hazards. They also use algorithms to plan cleaning paths for efficient and comprehensive cleaning; common path planning methods include random and planned approaches.

[0003] Currently, tracked sweeping robots use lifting wheels to automatically overcome obstacles to ensure smooth movement, and are equipped with tracked cleaning mechanisms to improve floor cleaning effectiveness. During long-term use, the thick cloth on the tracked cleaning mechanism needs to be replaced regularly to ensure cleaning effectiveness, but replacement often involves replacing the entire tracked cleaning mechanism, resulting in high maintenance costs.

[0004] To address the aforementioned issues, this utility model document proposes a tracked obstacle-crossing cleaning component and its sweeping robot. Utility Model Content

[0005] This utility model provides a tracked obstacle-crossing cleaning component and its sweeping robot, which solves the problem that in the prior art, the thick velvet cloth on the tracked cleaning mechanism needs to be replaced regularly during long-term use to ensure the cleaning effect, but the replacement often involves replacing the entire tracked cleaning mechanism, resulting in high maintenance costs.

[0006] This utility model provides the following technical solution:

[0007] A tracked obstacle-crossing sweeping assembly includes:

[0008] Two mounting pieces are symmetrically mounted with two rotating rollers between them. The same thick velvet cloth for cleaning the floor is connected to the two rotating rollers. The edges of the thick velvet cloth are sealed by a sewn zipper.

[0009] In one possible design, the first transmission rod at the center of the rotating roller passes through the outer wall of one of the mounting plates and is fixedly mounted with a corresponding synchronous pulley, and the two synchronous pulleys are connected by the same synchronous belt.

[0010] In one possible design, the surface of the rotating roller is provided with a plurality of protrusions in a circular array to increase its friction with the inner wall of the thick fleece.

[0011] This utility model also provides a sweeping robot, including the tracked obstacle-crossing sweeping component described in any one of the above, and a sweeping robot body. Both of the mounting plates can be detachably installed at the water spray nozzle at the bottom of the sweeping robot body. A first bevel gear is fixedly provided at the center of the outer side of one of the synchronous wheels, and a second bevel gear is fixedly provided at the bottom end of the second transmission rod driven inside the sweeping robot body. The second bevel gear meshes with the first bevel gear.

[0012] In one possible design, the bottom of the robot vacuum cleaner body is fixedly provided with an L-shaped limiting frame and a limiting plate for limiting corresponding mounting pieces respectively. One of the mounting pieces has a slot on its outer wall for engaging the end of the L-shaped limiting frame. The slot is located below the first bevel gear and the second bevel gear. The limiting plate is symmetrically threaded with two bolts for reinforcement. The outer wall of the other mounting piece is provided with a threaded groove for threadedly engaging the end of the corresponding bolt.

[0013] In one possible design, the bottom of the robot vacuum cleaner body is rotatably equipped with steering wheels for steering movement, and two turntables are symmetrically rotatably arranged at the edge of the bottom of the robot vacuum cleaner body. The turntables are equipped with multiple side brushes for sweeping garbage to the central suction port.

[0014] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0015] The working principle and usage process of this technical solution are as follows:

[0016] When the tracked obstacle-crossing sweeping robot is started, its internal drive unit begins to work. Power is transmitted to the second bevel gear at the bottom through the second transmission rod. Since the second bevel gear meshes with the first bevel gear, the first bevel gear drives the synchronous wheel fixed with it to rotate. Through the transmission of the synchronous belt, another synchronous wheel also begins to rotate synchronously, which in turn drives the rotating roller to rotate. This causes the thick cloth on the rotating roller to start circulating and moving, preparing for the cleaning work. The sweeping robot can flexibly turn and move under the action of the steering wheel, and travels according to the preset path in the cleaning area. When it encounters an obstacle, it can overcome the obstacle by using the lifting wheels equipped at the bottom, ensuring that the robot can continue to move forward smoothly. During the movement, the turntable located at the bottom edge of the robot rotates under the drive of the motor. Multiple side brushes on the turntable sweep and gather the surrounding garbage towards the central suction port. At the same time, the thick cloth continuously circulates and moves under the drive of the rotating roller, contacting the ground and wiping and cleaning the ground, adsorbing dust, stains and other dirt on the surface of the thick cloth.

[0017] As usage time increases, the cleaning effect of the thick cloth decreases, requiring replacement. To do this, first unscrew the bolts connecting the symmetrical threads on the limit plate to separate the mounting plate from the limit plate. Then, remove the mounting plate, which is engaged with the end slot of the L-shaped limit frame, from the L-shaped limit frame. This allows you to remove the entire tracked obstacle-crossing cleaning assembly from the water spray nozzle at the bottom of the tracked obstacle-crossing sweeping robot. By unzipping the zipper sewn along the edge of the thick cloth, remove the old cloth from the rotating roller, replace it with a new cloth, and then zip it back up. Following the reverse order of disassembly, reinstall the tracked obstacle-crossing cleaning assembly back onto the bottom of the robot to complete the replacement of the thick cloth.

[0018] This utility model has the following beneficial effects:

[0019] This invention features a sewn zipper along the edge of the thick fleece fabric, allowing the fleece fabric to be replaced individually without replacing the entire tracked cleaning mechanism, thus significantly reducing maintenance costs.

[0020] In this invention, multiple protrusions arranged in a ring array on the surface of the rotating roller increase the friction between the rotating roller and the inner wall of the thick fleece, effectively preventing the thick fleece from slipping on the rotating roller and ensuring that the thick fleece can rotate stably with the rotating roller, thus better achieving the cleaning function.

[0021] The L-shaped limiting frame, limiting plate, slot, bolt, and threaded groove set at the bottom of the tracked obstacle-crossing sweeping robot body in this utility model not only realize the detachable connection between the tracked obstacle-crossing sweeping component and the robot body, facilitating the replacement of the thick velvet cloth, but also accurately limit the installation plate, ensuring the correct meshing of the first bevel gear and the second bevel gear, and ensuring stable power transmission.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example

[0031] Please refer to Figure 3-4 A tracked obstacle-crossing sweeping assembly, comprising:

[0032] Two mounting plates 1 serve as the main support structure of the component and are symmetrically arranged. Between the two mounting plates 1, two rotating rollers 2 are installed by rotational mounting. These two rotating rollers 2 can rotate freely between the mounting plates 1. To achieve the floor cleaning function, a thick velvet cloth 3 is connected between the two synchronous wheels 6. The thick velvet cloth 3 has good adsorption capacity and wear resistance, and can effectively remove dust and stains on the floor. To ensure that the edge of the thick velvet cloth 3 will not loosen or fall off, a zipper 8 is installed at the edge of the thick velvet cloth 3 by sewing. When it is necessary to replace the thick velvet cloth 3, the zipper 8 can be easily opened for replacement.

[0033] The first transmission rod 5 in the center of the rotating roller 2 passes through the outer wall of one of the mounting plates 1 and is fixedly mounted with a corresponding synchronous wheel 6. In this way, when the rotating roller 2 rotates, it can drive the synchronous wheel 6 to rotate together. In addition, a synchronous belt 7 is also connected between the two synchronous wheels 6 to further ensure that the two synchronous wheels 6 can rotate synchronously. In order to increase the friction between the rotating roller 2 and the inner wall of the thick velvet 3 and prevent the thick velvet 3 from sliding or falling off during rotation, multiple protrusions 4 are arranged in a ring array on the surface of the rotating roller 2.

[0034] Please refer to Figure 1-2 This utility model also provides a sweeping robot, which includes the tracked obstacle-crossing sweeping component of any of the above-mentioned components, and a sweeping robot body 9. The sweeping robot body 9 is model R23H01B. Two mounting plates 1 can be easily disassembled and installed at the water spray nozzle 10 at the bottom of the sweeping robot body 9 to achieve simultaneous water spraying and sweeping. In order to realize the driving function, a first bevel gear 13 is fixedly set at the center of the outer side of one of the synchronous wheels 6. Inside the sweeping robot body 9, there is a second transmission rod 14 driven by the robot body. The bottom end of the second transmission rod 14 is fixedly connected to a second bevel gear 15. When the sweeping robot body 9 is working, the second bevel gear 15 will drive the first bevel gear 13 to rotate, thereby driving the synchronous wheel 6 and the thick cloth 3 to perform cleaning work.

[0035] At the bottom of the robot vacuum cleaner body 9, an L-shaped limiting frame 11 and a limiting plate 16 are fixedly installed. These two structures are used to limit the corresponding mounting pieces 1 to ensure the stability and firmness of the mounting pieces 1 on the robot vacuum cleaner body 9. The end of the L-shaped limiting frame 11 can be engaged in the slot 12 provided on the outer wall of the mounting piece 1. The slot 12 is located below the first bevel gear 13 and the second bevel gear 15. In addition, two bolts 17 are symmetrically threaded on the limiting plate 16, and the outer wall of the other mounting piece 1 is provided with a threaded groove 18 for threaded connection of the end of the bolt 17. In this way, by tightening the bolts 17, the connection of the mounting piece 1 on the robot vacuum cleaner body 9 can be further strengthened.

[0036] A steering wheel 19 is rotatably mounted on the bottom of the robot vacuum body 9, which enables the robot vacuum to turn and move. In addition, two turntables 20 are symmetrically mounted on the bottom edge of the robot vacuum body 9, and each turntable 20 is equipped with multiple side brushes 21. These side brushes 21 can sweep the debris around the robot vacuum body 9 to the central suction port, thereby further improving the cleaning efficiency of the robot vacuum.

[0037] This application can be used for robotic vacuum cleaners, or for other fields applicable to this application.

[0038] However, as is well known to those skilled in the art, the working principle and wiring method of the robot vacuum cleaner body 9 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
