Description

Technical Field

[0001] This application relates to the technical field of cleaning robots, and particularly to a cleaning robot with high cleaning efficiency. Background Art

[0002] Traditional cleaning robots are very popular in Europe, America, South Korea and Japan, and have also been popularizing in China in recent years at a doubling rate every year. However, traditional cleaning robots only belong to the category of household appliances, and true intelligence is out of the question. Compared with traditional cleaning robots, intelligent cleaning robots include a dual-mode anti-collision induction system, a self-rescue anti-jamming function, automatic charging, autonomous navigation path planning, are equipped with a wide-angle camera (120°), 15 groups of infrared induction devices, have a routing WIFI function, can be directly remotely controlled by a mobile phone app, and can also take pictures and share videos at the same time.

[0003] With the gradual popularization of cleaning robots, cleaning robots have begun to be used for cleaning urban road environments. Currently, the cleaning structures of common cleaning robots mostly involve a motor driving a set of rollers to rotate, and the bristles installed on the outer surface of the rollers are used to clean the garbage on the ground, so that the garbage no longer adheres to the ground, and then the garbage is sucked into the storage box by the suction nozzle installed on the cleaning robot for storage, so as to achieve the cleaning of the garbage.

[0004] However, when the cleaning robot is used for road cleaning in mountainous cities, due to the relatively complex road environment in mountainous cities, especially there are many potholes or undulating obstacles in the road, the contact time between the bristles and the ground is short or the contact effect is poor. In order to ensure the cleaning effect of the cleaning robot, only the walking speed of the cleaning robot can be reduced, thereby reducing the cleaning efficiency of the cleaning robot. Summary of the Utility Model

[0005] In order to improve the cleaning efficiency of the cleaning robot, this application provides a cleaning robot with high cleaning efficiency.

[0006] The cleaning robot with high cleaning efficiency provided by this application adopts the following technical solutions:

[0007] A cleaning robot with high cleaning efficiency includes a vehicle body, a walking component arranged on the vehicle body and used to drive the vehicle body to walk on the ground, and a cleaning mechanism arranged on the vehicle body and used to clean the ground. The cleaning mechanism includes:

[0008] A first rolling brush component, which is arranged on the vehicle body and used to sweep the garbage near the edge of the vehicle body towards the middle of the vehicle body;

[0009] A second rolling brush component, which is arranged on the vehicle body through a buffer component and makes the second rolling brush component always press tightly against the ground;

[0010] A suction component, which is arranged on the vehicle body and is used to suck and store the garbage on the ground. The second brush roller component sweeps the garbage after being swept by the first brush roller component to the suction component and sucks and stores it through the suction component.

[0011] By adopting the above technical solution, the walking component drives the vehicle body to walk on the ground. The first brush roller component sweeps the garbage at the edge of the vehicle body towards the middle of the vehicle body. Then, the second brush roller component sweeps the garbage towards the suction component, and the suction component sucks and stores the garbage. At the same time, the buffer component pushes the second brush roller component towards the end close to the ground, so that the second brush roller component presses tightly on the ground, thereby improving the cleaning efficiency of the cleaning robot.

[0012] Furthermore, the first brush roller component includes:

[0013] A first drum, which is rotatably arranged on the vehicle body. The axis of the first drum is parallel to the ground and the extension line of the axis of the first drum intersects with the center line of the vehicle body. The distance from the first drum to the center of the vehicle body is smaller when it is closer to the suction component;

[0014] First bristles, which are arranged in a spiral shape on the first drum and are used to sweep the garbage towards the middle of the vehicle body;

[0015] A first driving member, which is arranged on the vehicle body and is used to drive the first drum to rotate.

[0016] By adopting the above technical solution, the first driving member drives the first drum to rotate, and then drives the first bristles to rotate with the first drum. At the same time, the spiral first bristles are convenient for sweeping the garbage towards the middle of the vehicle body, so as to clean the garbage on the ground.

[0017] Furthermore, there are two groups of the first brush roller components, and the two groups of the first brush roller components are symmetrically arranged along the center line of the vehicle body and are used to sweep the garbage at the two edges of the vehicle body towards the middle of the vehicle body.

[0018] By adopting the above technical solution, the two groups of the first brush roller components are symmetrically installed on the vehicle body, so as to sweep the garbage at both ends of the vehicle body towards the middle of the vehicle body, thereby improving the cleaning efficiency.

[0019] Furthermore, a groove for placing the buffer component is formed on the vehicle body, and the buffer component includes:

[0020] A sliding plate, which is slidably arranged in the groove along the direction close to or away from the ground;

[0021] A telescopic rod, the cylinder body of the telescopic rod is arranged at the bottom of the groove, and the piston rod of the telescopic rod is fixedly arranged on the sliding plate;

[0022] A compression spring is sleeved on the telescopic rod. The two ends of the compression spring respectively abut against the bottom of the groove and the end face of the sliding plate and are used to push the sliding plate to move towards the end close to the ground.

[0023] By adopting the above technical solution, the telescopic rod guides the sliding direction of the sliding plate, and the compression spring is used to push the sliding plate away from the bottom of the groove, so that the second brush assembly always abuts against the ground, improving the cleaning efficiency of the robot.

[0024] Furthermore, the second brush assembly includes:

[0025] A second roller is rotatably arranged at one end of the sliding plate close to the ground, and the axis of the second roller is perpendicular to the center line of the vehicle body;

[0026] Second bristles are arranged at intervals on the side wall of the second roller and are used to sweep the garbage on the ground;

[0027] A second driving member is arranged on the sliding plate and is used to drive the second roller to rotate.

[0028] By adopting the above technical solution, the second driving member drives the second roller to rotate, and then drives the second bristles to roll and contact the ground, so that the second bristles can sweep the garbage on the ground.

[0029] Furthermore, multiple groups of second brush assemblies are arranged on the vehicle body in the width direction of the vehicle body through a buffer assembly. The second brush assemblies correspond to the buffer assembly one by one, and multiple groups of second brush assemblies jointly sweep the garbage on the ground into the suction assembly.

[0030] By adopting the above technical solution, multiple groups of second brush assemblies are installed on the vehicle body at intervals, so as to improve the cleaning range of the second brush assemblies on the ground. At the same time, when there are potholes or undulating obstacles on the ground passed by the vehicle body, the second brush assemblies at the corresponding positions always abut against the ground under the buffering action of the buffer assembly, so as to ensure the cleaning efficiency of the second brush assemblies.

[0031] Furthermore, adjacent sliding plates are slidably clamped and matched with each other. A dovetail groove is formed at one end of the sliding plate, and a convex block is arranged at the other end of the sliding plate. The convex blocks and the dovetail grooves on adjacent two groups of sliding plates are clamped and matched with each other, and the convex blocks can slide in the dovetail grooves.

[0032] By adopting the above technical solution, when adjacent two sliding plates slide relative to each other, through the mutual sliding and clamping cooperation of the convex blocks and the dovetail grooves, the stability of the sliding plates during sliding is improved.

[0033] Furthermore, the suction assembly includes:

[0034] A storage box, which is arranged on the vehicle body and used for storing garbage;

[0035] A suction nozzle, which is arranged on the vehicle body and communicated with the storage box through a pipeline, and is used for sucking garbage into the storage box;

[0036] A blower, which is arranged on the vehicle body and used for providing negative pressure suction for the suction nozzle.

[0037] By adopting the above technical solution, the blower generates negative pressure suction, so that there is a large suction force at the suction nozzle, and the suction nozzle sucks the garbage on the ground into the storage box through the pipeline.

[0038] Further, the walking assembly includes:

[0039] Tracks, multiple groups of which are arranged on the vehicle body at intervals and used for driving the vehicle body to walk on the ground;

[0040] A driving motor, which is fixedly installed on the vehicle body and used for driving the tracks to rotate.

[0041] By adopting the above technical solution, the driving motor is used for driving the tracks to rotate, so as to make the vehicle body walk stably on the ground.

[0042] In summary, the present application includes at least one of the following beneficial technical effects:

[0043] The vehicle body is driven to walk on the ground by tracks. The garbage on both sides of the vehicle body is swept towards the middle of the vehicle body by the first roller and the first brush bristles, and then the second roller and the second brush bristles cooperate with each other to sweep the garbage towards the suction nozzle. The suction nozzle sucks the garbage into the storage box. At the same time, the sliding plate is pushed towards the end close to the ground by the compression spring, so that the second brush bristles installed on the second roller are pressed tightly against the ground, thereby improving the cleaning efficiency of the cleaning robot.
