[0036] The present application provides a cleaning robot, which can be a device capable of autonomously traveling on the ground to perform cleaning actions such as dust suction, mopping, washing, etc. on the ground, such as a sweeper, a mop, a mop-sweeper integrated device, etc. The cleaning robot can also be a device that performs cleaning actions such as dust suction, mopping, washing, etc. on the ground under the holding or operation of a user, such as a handheld dust collector, a handheld mop, etc.

[0037] Please refer to Figure 1 and Figure 2 or Figure 4 and Figure 5The cleaning robot 1000 comprises a shell 100, a rolling brush 200, a driving module 300, a walking module 400, a main control module 500 and other components, the rolling brush 200, the walking module 400, the driving module 300 and the main control module 500 are all installed on the shell 100, and the driving module 300 and the walking module 400 work under the control of the main control module 500.

[0038] The shell 100 not only serves as a bearing structure for other components of the cleaning robot 1000, but also serves as an appearance structure of the cleaning robot 1000. The shell 100 can have various shapes, such as a cylindrical shape, a square column shape or other shapes. Preferably, the shell 100 is in a cylindrical shape, which can improve the overall aesthetics of the cleaning robot 1000.

[0039] The shell 100 is provided with a bottom-opened installation cavity 110, which can have various shapes, such as a cylindrical cavity or a square cavity. Without specific limitation, the installation cavity 110 is preferably in a cylindrical shape, considering that the installation cavity 110 is mainly used for installing the rolling brush 200.

[0040] The opening of the installation cavity 110 is formed at the bottom of the shell 100, so that when the shell 100 is placed on a surface to be cleaned, the opening of the installation cavity 110 faces the surface to be cleaned. The opening of the installation cavity 110 can have various shapes, such as a rectangular shape, an elliptical shape or other shapes. Preferably, the opening of the installation cavity 110 is in a rectangular shape, so as to facilitate the rolling brush 200 to extend out of the opening of the installation cavity 110.

[0041] The rolling brush 200 is usually in a cylindrical shape and is rotatably installed in the installation cavity 110 and in clearance fit with the cavity wall of the installation cavity 110. The rolling brush 200 is rotatably connected to the shell 100 at both ends in the axial direction. The rolling brush 200 and the shell 100 can be rotatably connected in various ways, such as through a rotating shaft and a bearing, or through a rotating shaft and a shaft sleeve.

[0042] When the rolling brush 200 is installed in the installation cavity 110, part of it extends out of the opening of the installation cavity 110, so that the outer peripheral wall of the rolling brush 200 can be in contact with the ground. For example, the volume of the rolling brush 200 extending out of the opening of the installation cavity 110 is one-fifth of its own volume, or the volume of the rolling brush 200 extending out of the opening of the installation cavity 110 is one-fourth of its own volume. Here, they are not listed one by one.

[0043] The driving module 300 is used to drive the rolling brush 200 to rotate relative to the shell 100. The driving module 300 can be composed of a motor and a shaft coupling, one end of the shaft coupling is connected with the output shaft of the motor, and the other end of the shaft coupling is connected with the rolling brush 200. The driving module 300 can also be composed of a reduction box and a motor, the input end of the reduction box is connected with the output shaft of the motor, and the output end of the reduction box is connected with the rolling brush 200. Here, the driving module 300 will not be listed one by one.

[0044] The walking module 400 is installed on the shell 100 and is used to drive the shell 100 to travel on the ground. The walking module 400 can be composed of two track structures and two motors. The two track structures are arranged on the left and right sides of the bottom of the shell 100. The two motors are respectively in transmission connection with the corresponding track structures. The two motors work to drive the corresponding track structures to rotate, so as to drive the shell 100 to travel on the ground.

[0045] The walking module 400 can be composed of a steering motor, two power motors, two drive wheels and universal wheels. The two drive wheels are respectively arranged on the left and right sides of the bottom of the shell 100. The two power motors are respectively in transmission connection with the corresponding drive wheels. The universal wheels can be arranged on the front or rear part of the shell 100. The steering motor is used to drive the universal wheels to steer. The two drive wheels rotate under the drive of the corresponding motors, so as to drive the shell 100 to travel on the ground.

[0046] The main control module 500 can be a single-chip microcomputer, a PWM controller, a microcontroller and other structures with receiving and sending signals. Here, the type of the controller is not limited. The main control module 500 is electrically connected with the walking module 400 and the driving module 300. The main control module 500 can be electrically connected with the walking module 400 and the driving module 300 through wireless communication modes such as Bluetooth and WIFI. The main control module 500 can be connected with the walking module 400 and the driving module 300 through wires.

[0047] Considering that the open end of the installation cavity 110 is towards the ground, the rolling brush 200 cannot be directly observed when rotating in the installation cavity 110, which is not conducive to observing the working condition of the rolling brush 200. Therefore, at least part of the cavity wall of the installation cavity 110 is set as a transparent area 120. The position of the shell 100 above the transparent area 120 is set as an observation area 130. Meanwhile, a sealed observation space 140 is formed on the shell 100, which communicates the transparent area 120 and the observation area 130. A user can directly observe the rolling brush 200 through the observation area 130, the observation space 140 and the transparent area 120.

[0048] It should be noted that the transparent region 120 can be formed in many ways. For example, the cavity wall of the installation cavity 110 is made of transparent material to form the transparent region 120. For another example, the installation cavity 110 is provided with an opening, and a transparent plate is installed at the opening to form the transparent region 120. The transparent region 120 can also be formed in other ways, which are not listed here.

[0049] The observation region 130 can also be formed in many ways. For example, the shell 100 is made of transparent material to form the observation region 130. For another example, the shell 100 is provided with an opening, and a transparent plate is installed at the opening to form the observation region 130. The observation region 130 can also be formed in other ways, which are not listed here.

[0050] The observation space 140 is a closed space. The observation space 140 can be formed by a pipeline structure on the shell 100, or by a transparent capsule structure assembled into the shell 100, or in other ways, which are not listed here.

[0051] When the cleaning robot 1000 is working, the user can directly observe the working condition of the roller brush 200 when it rotates through the observation region 130, the observation space 140, and the transparent region 120. This makes it easier for the user to more intuitively understand the working state of the roller brush 200 of the robot, so that the user can timely find out whether the roller brush 200 is working abnormally. Since the observation region 130 and the transparent region 120 are connected through the closed observation space 140, it is not easy for dust to enter the observation space 140, which connects the observation region 130 and the transparent region 120. Thus, the observation space 140 can maintain a good perspective effect for a long time.

[0052] Considering that the cleaning robot 1000 has many components, in order to facilitate the assembly of the cleaning robot 1000, the shell 100 of the cleaning robot 1000 is usually formed by connecting multiple parts. For details, please refer to Figure 1 and Figure 2 or Figure 4 and Figure 5 The shell 100 includes an upper cover 150, a middle sweeping bracket 160, and a lower cover 170. The upper cover 150 is installed above the lower cover 170 and surrounds a containing space together with the lower cover 170. The middle sweeping bracket 160 is assembled to the lower cover 170, and the middle sweeping bracket 160 is formed with the installation cavity 110 with an open bottom.

[0053] The driving module 300, the main control module 500 and the walking module 400 are all mounted on the lower cover 170, the rolling brush 200 is assembled to the middle sweeping bracket 160, the middle sweeping bracket 160 is further provided with a dust outlet 161 which is in communication with the mounting cavity 110, the dust collecting box 600 and the fan 700 are further assembled between the upper cover 150 and the lower cover 170, the dust collecting box 600 is in communication with the dust outlet 161, the fan 700 is in communication with the dust collecting box 600, and the fan 700 drives air flow, so that the dust, debris and other dirt brushed by the rolling brush 200 can be sucked into the dust collecting box 600.

[0054] Since the mounting cavity 110 is formed on the middle sweeping bracket 160, the transparent area 120 is formed on the middle sweeping bracket 160, and since the upper cover 150 covers the entire lower cover 170 and the middle sweeping bracket 160, the observation area 130 is formed at the position of the upper cover 150 above the middle sweeping bracket 160, and the sealed observation space 140 is correspondingly formed between the upper cover 150 and the lower cover 170.

[0055] It should be noted that the observation space 140 can be formed in various ways, and in some embodiments of the present application, the observation space 140 is a cavity structure formed by the upper cover 150, the lower cover 170, the middle sweeping bracket 160 and the plate structure. Specifically, please refer to Figure 1 and Figure 2 The middle sweeping bracket 160 is sealingly connected with the lower cover 170, the upper cover 150 is sealingly connected with the lower cover 170, and the cleaning robot 1000 further comprises a partition plate 800 which cooperates with the upper cover 150, the lower cover 170 and the middle sweeping bracket 160 to form the observation space 140.

[0056] Since the observation space 140 does not need to cover the entire mounting cavity 110, the partition plate 800 only needs to be partially surrounded by the upper cover 150, the lower cover 170 and the middle sweeping bracket 160 to form the observation space 140, and preferably, the partition plate 800 only needs to be partially surrounded by the front part of the upper cover 150 in the direction of travel of the cleaning robot 1000, the front part of the lower cover 170 in the direction of travel of the cleaning robot 1000 and the front part of the middle sweeping bracket 160 in the direction of travel of the cleaning robot 1000 to form the observation space 140.

[0057] In this way, not only can the installation of other components of the cleaning robot 1000 be affected by the installation of the observation space 140, thereby facilitating the layout of the components of the cleaning robot 1000, but also the area of the sealing connection between the middle sweeping bracket 160 and the lower cover 170 and the area of the sealing connection between the upper cover 150 and the lower cover 170 can be reduced, thereby reducing the assembly difficulty of the upper cover 150, the lower cover 170 and the middle sweeping bracket 160.

[0058] It is worth noting that the above-mentioned partition plate 800 can exist independently, and the partition plate 800 needs to be sealingly connected when being connected with the middle sweeping support 160 and the upper cover 150; the above-mentioned partition plate 800 can also be integrally formed with the middle sweeping support 160 or the upper cover 150, and the partition plate 800 only needs to be sealingly connected with the upper cover 150 or the middle sweeping support 160, and the setting of the partition plate 800 is not limited here.

[0059] Preferably, referring to Figure 3 the partition plate 800 is integrally formed with the middle sweeping support 160, the partition plate 800 is arranged along the axial direction of the rolling brush 200, both ends of the partition plate 800 in the length direction are sealingly connected with the side wall of the upper cover 150, and the side of the partition plate 800 away from the middle sweeping support 160 is sealingly connected with the top wall of the upper cover 150, so that the upper cover 150, the lower cover 170 and the middle sweeping support 160 together form the observation space 140.

[0060] Further, both ends of the partition plate 800 in the length direction and the side of the partition plate 800 away from the middle sweeping support 160 are covered with sealing strips (not shown), and when the upper cover 150 is assembled to the lower cover 170, the sealing strips can effectively seal the partition plate 800 and the upper cover 150 under the extrusion of the upper cover 150, so that the sealing connection between the partition plate 800 and the upper cover 150 can be achieved.

[0061] In other embodiments of the present application, the observation space 140 is formed by a tubular structure together with the upper cover 150 and the middle sweeping support 160. Specifically, referring to Figure 4 and Figure 5 the cleaning robot 1000 further includes a connecting piece 900, the connecting piece 900 is provided with an observation channel 910, the observation channel 910 is a linear channel or a channel close to a linear channel, one end of the connecting piece 900 abuts against the upper cover 150, and the other end of the connecting piece 900 abuts against the middle sweeping support 160, so that one end of the observation channel 910 is aligned with the transparent area 120, and the other end of the observation channel 910 is aligned with the observation area 130.

[0062] It is worth noting that the observation space 140 is sealingly arranged, and therefore the connecting piece 900 needs to be sealingly connected with the upper cover 150, the connecting piece 900 and the upper cover 150 can be sealed by a sealing glue, the connecting piece 900 and the upper cover 150 can also be sealed by a sealing pad, and the connecting piece 900 and the upper cover 150 can also be sealingly connected by other ways, which are not listed here.

[0063] Preferably, the connecting piece 900 is sealingly connected with the upper cover 150 through a sealing ring 950, the sealing ring 950 is simultaneously pressed by the upper cover 150 and the middle sweeping bracket 160 when the connecting piece 900 is assembled between the upper cover 150 and the middle sweeping bracket 160, so that the sealing ring 950 can sealingly abut against the upper cover 150 and the middle sweeping bracket 160, thereby eliminating the gap between the upper cover 150 and the connecting piece 900.

[0064] Further, please refer to Figure 7 The surface of the sealing ring 950 opposite to the upper cover 150 is concavely provided with a positioning groove 951 extending along the circumference thereof, the positioning groove 951 is used for plug-in cooperation with one end of the connecting piece 900 adjacent to the transparent area 120, in this way, the assembly of the connecting piece 900 and the sealing ring 950 is facilitated, and meanwhile, the assembly of the sealing ring 950 between the connecting piece 900 and the upper cover 150 is facilitated.

[0065] It should be noted that the connecting piece 900 is also sealingly connected with the middle sweeping bracket 160, and the sealing manner between the connecting piece 900 and the middle sweeping bracket 160 can refer to the sealing manner between the connecting piece 900 and the upper cover 150. Figure 6 Preferably, please refer to

[0066] In some other embodiments of the present application, the observation space 140 is formed by a transparent capsule structure, specifically, the cleaning robot 1000 further comprises an elastic air bag (not shown) made of transparent material, the elastic air bag is mounted between the upper cover 150 and the middle sweeping bracket 160, and the elastic air bag abuts against the transparent area 120 and the observation area 130 respectively, so as to form the observation space 140.

[0067] It should be noted that the elastic air bag can still produce elastic deformation after being inflated, therefore, when the elastic air bag is assembled between the middle sweeping bracket 160 and the upper cover 150, the elastic air bag can produce elastic deformation under the extrusion of the middle sweeping bracket 160 and the upper cover 150, so that the elastic air bag can abut against the observation area 130 of the upper cover 150 and the transparent area 120 of the middle sweeping bracket 160, thereby facilitating the formation of the observation space 140.

[0068] In consideration of the fact that the air in the elastic air bag will be lost after a long time of use, the cleaning robot 1000 further comprises an air pump (not shown) and an air pressure detection device (not shown) for detecting the air pressure in the elastic air bag, the air pump being in communication with the elastic air bag pipeline, and a one-way valve (not shown) being further arranged on the pipeline connecting the air pump and the elastic air bag to ensure that air can only enter the elastic air bag, the air pump and the air pressure detection device both being electrically connected with the main control module 500 of the cleaning robot 1000, and the main control module 500 controls the air pump to work according to the air pressure detection device.

[0069] When the real-time air pressure value in the elastic air bag detected by the air pressure detection device is lower than the preset air pressure value, the main control module 500 controls the air pump to start to inflate the elastic air bag; when the real-time air pressure value in the elastic air bag detected by the air pressure detection device is equal to or greater than the preset air pressure value, the main control module 500 controls the air pump to stop working. In this way, it can be ensured that the elastic air bag is always in abutment with the transparent area 120 and the observation area 130, so as to ensure that the transparent area 120 and the observation area 130 are always connected through a closed observation space 140.

[0070] Based on the above embodiments, it should be noted that the shell 100 of the cleaning robot 1000 has a certain thickness, if the observation area 130 is arranged at the top of the shell 100 and the transparent area 120 is arranged at the bottom of the shell 100, the height of the observation space 140 connecting the observation area 130 and the transparent area 120 will be higher. In view of this, in some embodiments of the present application, the distance between the observation area 130 and the transparent area 120 is reduced to reduce the height of the observation space 140.

[0071] Specifically, please refer to Figure 1 and Figure 8 or Figure 4 and Figure 8 The shell 100 has a front end and a rear end arranged opposite in the advancing direction of the cleaning robot 1000, the front end of the shell 100 is protruded forward to form a protruding portion 180 adjacent to the position of the ground, the mounting cavity 110 is at least partially formed in the protruding portion 180, the transparent area 120 is arranged below the protruding portion 180, and the observation area 130 is formed on the protruding portion 180.

[0072] It should be further noted that when the shell 100 is composed of the upper cover 150, the lower cover 170 and the middle sweeping bracket 160, the front end of the upper cover 150 is protruded forward adjacent to the position of the lower cover 170, and the front end of the lower cover 170 is correspondingly arranged to extend forward, and the two are connected to jointly constitute the protruding portion 180.

[0073] When the observation space 140 is formed by the partition 800 or the connecting piece 900 and the upper cover 150, the lower cover 170 and the middle sweeping bracket 160, a part of the partition 800 or the connecting piece 900 extends from the middle sweeping bracket 160 to the direction close to the upper cover 150 and abuts against the position of the front end of the upper cover 150 which is not protruded, so that the observation space 140 is formed in the protruded part 180.

[0074] Since the thickness of the protruded part 180 is smaller than the thickness of the shell 100, the height of the observation space 140 can be effectively reduced, and the observation space 140 is arranged in the position of the protruded part 180, so that the arrangement of the observation space 140 does not affect the arrangement of other parts of the cleaning robot 1000.

[0075] In addition, the installation cavity 110 is partially formed in the protruded part 180, so that the roller brush 200 can be further arranged in the front end of the shell 100, and since the protruded part 180 is arranged lower than the top of the shell 100, the cleaning robot 1000 can also effectively clean the space below the sofa, the space below the cabinet and the space below other articles, so that the problem that the cleaning robot 1000 cannot clean the space lower than the shell 100 due to the high height of the shell 100 is solved.

[0076] The above description is only the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made according to the content of the present application and the drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
