Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, specifically a cleaning robot with a floating side brush assembly. Background Technology

[0002] As an important device in the field of smart homes, cleaning robots, equipped with sensors, intelligent navigation systems and cleaning components, can automatically clean up dust, debris and hair on the ground, greatly reducing people's housework burden, and are widely used in homes, offices and other scenarios.

[0003] Referring to the patent document: Patent Publication No. CN217744227U, Patent Publication Date 2022-11-08, a floating roller brush assembly for a cleaning robot is disclosed, relating to the field of cleaning equipment technology. The cleaning robot includes a chassis and a roller brush assembly that can float up and down relative to the chassis. The chassis has a receiving cavity for accommodating the roller brush assembly. The roller brush assembly includes a roller brush shell, a roller brush placed laterally within the roller brush shell, and a drive motor for driving the roller brush to rotate. The roller brush shell is pivotally connected to the chassis via a rotating shaft. The horizontal distance from the central axis of the roller brush to the rear end of the roller brush shell is less than the horizontal distance from the central axis of the roller brush to the rotating shaft. This configuration shifts the center of gravity of the roller brush assembly away from the rotating shaft, resulting in better floating effect when cleaning the floor, thereby applying greater pressure to the floor, increasing the adhesion between the roller brush and the floor, and improving the cleaning effect.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Currently, most existing cleaning robots with side brush structures are fixedly installed, making it impossible to adjust the extension length of the side brush according to actual conditions. This can cause the cleaning robot to be unable to pass through narrow passages or get stuck in the middle. Furthermore, the side brush cannot adapt to complex environments such as wall undulations and obstacles, making it difficult to effectively clean dust and debris on the baseboard.

[0006] Therefore, this utility model provides a cleaning robot with a floating side brush assembly. Utility Model Content

[0007] To address the issue that existing cleaning robots mostly use fixed installation methods, resulting in poor flexibility and an inability to adapt to actual needs, the purpose of this invention is to provide a cleaning robot with a floating side brush assembly.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cleaning robot with a floating side brush assembly, comprising a main body, wherein a cleaning mechanism is provided on the outer side of the main body for cleaning the baseboard area of ​​the wall, the cleaning mechanism comprising:

[0009] The extension components include a rotating disk rotatably mounted in the middle of the main body of the cleaning robot. A drive component is located at the top center of the rotating disk. Four evenly distributed drive slots are opened in the middle of the rotating disk. A drive block is slidably engaged in the middle of each of the four drive slots. A movable plate is fixedly mounted at the bottom of each of the four drive blocks. One end of each of the four movable plates is fixed to a limiting housing. A mounting shell is slidably engaged in the middle of one side of each of the four limiting housings. Two cleaning rollers that cooperate with each other are rotatably mounted in the middle of each of the four mounting shells.

[0010] An adaptive component, located on one side of the limiting housing, is used to cushion the mounting housing so that its cleaning rollers can adjust adaptively.

[0011] Preferably, the adaptive component includes an inner sleeve fixedly installed on one side of the limiting housing. The inner sleeve has four evenly distributed inner sleeves. A buffer spring is fixedly installed in the middle of each of the four inner sleeves. An outer sleeve is slidably attached to the outside of one side of each of the four inner sleeves. An inner slide rod is fixedly installed in the middle of one side of each of the four outer sleeves. One side of each of the four inner slide rods slides through the middle of one side of each inner sleeve. One end of each of the four buffer springs is fixedly installed in the middle of one side of each of the four outer sleeves. One side of each of the four inner slide springs is fixedly installed in the middle of one side of each inner sleeve.

[0012] Preferably, the drive assembly includes a motor fixed to the upper part of the cleaning robot body, and the top of the rotating disk is fixedly installed on the drive end of the motor.

[0013] Preferably, the outer side of the main body of the cleaning robot is provided with four evenly distributed limiting grooves, and the four limiting shells are slidably locked in the middle of the limiting grooves.

[0014] Preferably, two symmetrically distributed pipes are fixedly installed on the middle of one side of each of the four mounting shells, and one side of each of the multiple pipes slides through one side of the limiting shell.

[0015] Preferably, two symmetrically distributed sliders are fixedly installed on the outer surfaces of the multiple inner sleeves, and grooves corresponding to the sliders are opened in the middle of the multiple outer sleeves, with the sliders slidingly engaged inside the grooves.

[0016] Beneficial effects

[0017] This invention provides a cleaning robot with a floating side brush assembly. Compared with the prior art, it has the following advantages:

[0018] 1. This application uses a motor to drive the rotating disk to rotate. By utilizing the sliding cooperation between the drive groove and the drive block, the four limiting shells and the mounting shell can extend and retract along the outside of the main body of the cleaning robot. When the cleaning robot is in special terrains such as narrow passages or corners, the extension length of the cleaning roller can be adaptively adjusted so that it can pass through narrow areas and effectively clean dust and debris from the baseboard area, greatly improving the applicability and cleaning coverage of the cleaning robot in different terrains.

[0019] 2. When the cleaning robot encounters an uneven wall surface, the pressure generated by the protrusions or depressions on the wall surface causes the mounting shell to move into the limiting shell. This causes the outer sleeve in the adaptive component to slide towards the inner sleeve, compressing the straight spring and the buffer spring, converting the pressure into elastic potential energy. As the wall surface condition changes, when the pressure disappears or decreases, the elastic potential energy is released, causing the mounting shell to reset. This ensures that the cleaning roller always adheres to the wall surface with appropriate pressure. Even if there are minor unevennesses on the wall surface, the cleaning roller can adaptively adjust its position to continuously and efficiently clean the wall dust, avoiding cleaning omissions caused by uneven wall surfaces.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a cleaning robot with a floating side brush assembly, including a cleaning robot body 1, and a cleaning mechanism 2 on the outer side of the cleaning robot body 1 for cleaning the baseboard area of ​​the wall. The cleaning mechanism 2 includes:

[0028] The expansion component 21 includes a rotating disk 211 rotatably mounted in the middle of the main body 1 of the cleaning robot. A drive component is provided at the top center of the rotating disk 211. Four evenly distributed drive slots 212 are formed in the middle of the rotating disk 211. A drive block 213 is slidably engaged in the middle of each of the four drive slots 212. A movable plate 215 is fixedly mounted at the bottom end of each of the four drive blocks 213. One end of each of the four movable plates 215 is fixed to a limiting housing 216. A mounting shell is slidably engaged in the middle of one side of each of the four limiting housings 216. 219, each of the four mounting housings 219 has two cleaning rollers 218 that rotate and cooperate with each other. The surface of the cleaning rollers 218 is covered with high-density nylon bristles, which are arranged in a spiral shape to improve cleaning efficiency. The cleaning rollers 218 are driven by a conventional servo motor, which will not be described in detail here. This allows the two cleaning rollers 218 to move relative to each other at the same time, rolling the garbage they have swept into the middle of the mounting housing 219. The dust and debris swept up are then absorbed and cleaned by the vacuuming equipment and the pipe 217.

[0029] An adaptive component 22 is disposed on one side of the limiting housing 216 to buffer the mounting housing 219 so that the cleaning roller 218 can be adaptively adjusted.

[0030] The adaptive component 22 includes an inner sleeve 221 fixedly installed on one side of the limiting housing 216. The inner sleeve 221 has four evenly distributed inner sleeves. A buffer spring 225 is fixedly installed in the middle of each of the four inner sleeves 221. An outer sleeve 222 is slidably attached to the outside of one side of each of the four inner sleeves 221. An inner slide rod 224 is fixedly installed in the middle of one side of each of the four outer sleeves 222. One side of each of the four inner slide rods 224 slides through the middle of one side of the inner sleeve 221. One end of each of the four buffer springs 225 is fixedly installed in the middle of one side of the inner slide rod 224. A straight spring 223 is fixedly installed in the middle of one side of each of the four outer sleeves 222. One side of each of the four straight springs 223 is fixedly installed in the middle of one side of the inner sleeve 221.

[0031] The drive assembly includes a motor 214 fixed on the upper part of the cleaning robot body 1. The top of the rotating disk 211 is fixedly installed on the drive end of the motor 214. The motor 214 can be an AC permanent magnet synchronous servo motor. The motor 214 is connected to the circuit through a dedicated servo driver. At the same time, the driver can be connected to the control system of the cleaning robot body through a communication interface to receive motion commands and upload running status data to achieve precise automated control.

[0032] The outer side of the cleaning robot body 1 is provided with four evenly distributed limiting grooves 2161. The four limiting shells 216 are slidably locked in the middle of the limiting grooves 2161, which can be used to limit the limiting shells 216, ensuring that they can move telescopically along the limiting grooves 2161 under the drive of the motor 214. At the same time, when not in use, the mounting shell 219 is also located inside the limiting grooves 2161, so that its cleaning roller 218 is flush with the outer wall of the cleaning robot body 1, thereby reducing the volume of the cleaning robot body 1 and making it more convenient.

[0033] Two symmetrically distributed pipes 217 are fixedly installed on the middle of one side of each of the four mounting shells 219. One side of each pipe 217 slides through one side of the limiting shell 216. One end of each pipe 217 is connected to the dust suction component of the cleaning robot body 1 for cleaning and adsorbing the ground, so that it can adsorb and collect the dust and debris swept into the mounting shell 219 by the cleaning roller 218, and store them in the garbage storage box.

[0034] Two symmetrically distributed sliders 226 are fixedly installed on the outer surface of multiple inner sleeves 221. The middle of multiple outer sleeves 222 is provided with a groove corresponding to the slider 226, and the slider 226 is slidably locked inside the groove. Under the limitation of the slider 226 and the groove, the outer sleeve 222 can be stably slid on the outside of the inner sleeve 221 without rotation, thus avoiding damage to the internal straight spring 223 and buffer spring 225.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, the rotating disk 211 is driven by the motor 214 to rotate, which causes the drive block 213 to move under the limit of the drive groove 212. This causes the four limiting shells 216 installed around the main body of the cleaning robot 1 to expand outward at the same time, that is, the mounting shell 219 moves outward, so that the cleaning roller 218 comes into contact with the baseboard at the corner. The two cleaning rollers 218 installed on the mounting shell 219 are driven by the micro servo motor to rotate relative to each other. Driven by the drive component of the main body of the cleaning robot 1, the main body of the cleaning robot 1 moves, which in turn drives the cleaning roller 218 to move. Through the contact movement of the cleaning roller 218 with the baseboard, the dust and debris attached to the surface are swept to the middle of the mounting shell 219. By connecting one end of the pipe 217 to the dust suction component of the main body of the cleaning robot 1 for cleaning and adsorption of the ground, it can adsorb and collect the dust and debris swept into the mounting shell 219 by the cleaning roller 218, and store it in the garbage storage box.

[0037] When encountering an uneven wall surface, the cleaning roller 218 is squeezed under pressure, causing its mounting shell 219 to move inward toward the limiting shell 216. This causes the outer sleeve 222 to move toward one side of the inner sleeve 221. The movement of the outer sleeve 222 compresses the straight spring 223, which converts the pressure into elastic potential energy. At the same time, it drives the inner slide rod 224 to compress the buffer spring 225, which in turn converts the pressure into elastic potential energy. When the pressure disappears or decreases, the elastic potential energy is released, which causes the mounting shell 219 to reset. This ensures that the cleaning roller 218 self-adjusts and always stays close to the wall surface for cleaning.
