[0010] The window-cleaning robot further comprises a second body, and the second body is provided with at least one magnetic matching piece;

[0011] The magnetic piece and the magnetic matching piece are used to magnetically attract each other when the first body and the second body are respectively located on two sides of a cleaning object.

The first magnetic element and the second magnetic element are arranged along a first direction, and the first magnetic element and the second magnetic element constitute a first magnetic assembly. The third magnetic element and the fourth magnetic element are arranged along the first direction, and the third magnetic element and the fourth magnetic element constitute a second magnetic assembly. The first magnetic assembly and the second magnetic assembly are arranged along a second direction.

[0014] In some possible implementations, both the magnetic component and the magnetic mating component are magnets.

Detailed Implementation

[0033] The terms "first," "second," and "third," etc., used in this application specification and accompanying drawings are used to distinguish different objects, not to limit a specific order.

[0034] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0035] To ensure clarity and conciseness in the description of the following embodiments, a brief introduction to the related technologies is given first:

[0036] Window cleaning robots are a type of cleaning device in modern smart homes. They can adhere to surfaces requiring cleaning using vacuum or magnetic adsorption. However, when using only vacuum or magnetic adsorption to attach the robot to vertical surfaces like window glass, the robot's weight makes it difficult to guarantee effective adhesion and poses a risk of it falling.

[0037] In view of this, this application provides a window cleaning robot that uses both vacuum adsorption and magnetic adsorption to adhere to the object to be cleaned, giving it strong adsorption force. When the window cleaning robot is adsorbed onto vertical objects such as window glass, the adsorption effect is guaranteed, greatly reducing the risk of the window cleaning robot falling.

[0038] The window cleaning robot provided in the embodiments of this application is described below, such as... Figures 1-5 As shown, the window cleaning robot includes a first body 10 and a second body 20. The first body 10 includes a mounting mechanism 1, at least one vacuum assembly 2, and at least one magnetic component 3. The mounting mechanism 1 is provided with a first space 11, an air inlet 12, and an exhaust outlet (not shown in the figure). The air inlet 12 and the exhaust outlet are respectively connected to the first space 11. The air inlet 12 is located at the bottom of the mounting mechanism 1. When the first body 10 is located on one side of the part to be cleaned 30, the air inlet 12 faces the part to be cleaned 30. The vacuum assembly 2 is disposed in the first space 11. The vacuum assembly 2 is used to discharge the air in the first space 11 through the exhaust outlet and to draw in air through the air inlet 12. The magnetic component 3 is fixed to the mounting mechanism 1. The second body 20 is provided with at least one magnetic mating component 201.

[0039] The magnetic component 3 and the magnetic mating component 201 are used to magnetically attract each other when the first body 10 and the second body 20 are located on both sides of the part to be cleaned 30.

[0040] When using this window cleaning robot to clean the part 30 to be cleaned, the first body 10 and the second body 20 are placed on both sides of the part 30 to be cleaned. The magnetic part 3 of the first body 10 and the magnetic mating part 201 of the second body 20 are magnetically attracted, so that the first body 10 and the second body 20 are adsorbed on both sides of the part 30 to be cleaned. At the same time, under the action of the vacuum component 2 of the first body 10, air is drawn into the first space 11 of the mounting mechanism 1 from the air inlet 12. The air in the first space 11 of the mounting mechanism 1 is discharged through the exhaust port, so that the first space 11 forms a negative pressure, and an adsorption force is generated at the air inlet 12. The air inlet 12 faces the part 30 to be cleaned. At this time, there is a vacuum adsorption effect between the first body 10 and the part 30 to be cleaned. Therefore, the window cleaning robot can be adsorbed on the part 30 to be cleaned by both magnetic adsorption and vacuum adsorption, so that the window cleaning robot can have a strong adsorption force. When the window cleaning robot is adsorbed on the vertical part 30 to be cleaned, such as the window glass, the adsorption effect can also be guaranteed, which greatly reduces the risk of the window cleaning robot falling.

[0041] Specifically, the exhaust port can be located on the top or side of the mounting mechanism 1.

[0042] The second body 20 and the first body 10 are similar in structure except that the magnetic mating part 201 and the magnetic part 3 are different.

[0043] In other embodiments, the second body 20 may also be a structure with only a magnetic mating member 201. The second body 20 is used to cooperate with the first body 10 so that the first body 10 is magnetically attracted to the part 30 to be cleaned.

[0044] Specifically, both the magnetic component 3 and the magnetic mating component 201 are magnets.

[0045] When the first body 10 and the second body 20 are located on opposite sides of the part to be cleaned 30, the magnetic poles of the magnet of the first body 10 facing the part to be cleaned 30 are opposite to the magnetic poles of the magnet of the second body 20 facing the part to be cleaned 30, so that the magnets of the first body 10 and the magnets of the second body 20 can be magnetically attracted, which makes it easy to ensure the magnetic attraction strength, thereby ensuring the adsorption effect of the first body 10 and the second body 20 on the part to be cleaned 30.

[0046] Preferably, both the magnetic component 3 and the magnetic mating component 201 are neodymium iron boron magnets.

[0047] Neodymium iron boron magnets have high magnetic properties, which enables the first body 10 and the second body 20 to be firmly attached to the part 30 to be cleaned.

[0048] In other embodiments, the magnetic component 3 may also be made of magnet, and the magnetic mating component 201 may also be made of iron.

[0049] In one specific embodiment, such as Figures 3-4 As shown, the first body 10 includes a first magnetic element 31 and a second magnetic element 32. When the first body 10 is located on one side of the part to be cleaned 30, the N pole of the first magnetic element 31 faces the part to be cleaned 30, and the S pole of the second magnetic element 32 faces the part to be cleaned 30.

[0050] N is the north pole of magnetic component 3, and S is the south pole of magnetic component 3.

[0051] With this configuration, a closed magnetic circuit is formed between the first magnetic element 31 and the second magnetic element 32, which strengthens the magnetic field in the area between the first magnetic element 31 and the second magnetic element 32, thereby increasing the magnetic attraction strength between the magnetic element 3 of the first body 10 and the magnetic mating element 201 of the second body 20.

[0052] Specifically, such as Figures 3-4As shown, the first body 10 also includes a third magnetic element 33 and a fourth magnetic element 34. When the first body 10 is located on one side of the part to be cleaned 30, the N pole of the third magnetic element 33 faces the part to be cleaned 30, and the S pole of the fourth magnetic element 34 faces the part to be cleaned 30. The first magnetic element 31 and the second magnetic element 32 are arranged along the first direction A, and the first magnetic element 31 and the second magnetic element 32 form a first magnetic assembly. The third magnetic element 33 and the fourth magnetic element 34 are arranged along the first direction A, and the third magnetic element 33 and the fourth magnetic element 34 form a second magnetic assembly. The first magnetic assembly and the second magnetic assembly are arranged along the second direction B.

[0053] With this configuration, a closed magnetic circuit is formed between the first magnetic element 31 and the second magnetic element 32, with magnetic field lines entering the S pole of the second magnetic element 32 from the N pole of the first magnetic element 31; a closed magnetic circuit is formed between the third magnetic element 33 and the fourth magnetic element 34, with magnetic field lines entering the S pole of the fourth magnetic element 34 from the N pole of the third magnetic element 33; since the first magnetic element 31 and the second magnetic element 32 are arranged along the first direction A, and the third magnetic element 33 and the fourth magnetic element 34 are also arranged along the first direction A, and the first magnetic assembly composed of the first magnetic element 31 and the second magnetic element 32 and the second magnetic assembly composed of the third magnetic element 33 and the fourth magnetic element 34 are arranged along the second direction B, the magnetic field direction of the first magnetic assembly is the same as that of the second magnetic assembly, the density of magnetic field lines between the first magnetic assembly and the second magnetic assembly is increased, the magnetic field strength between the first magnetic assembly and the second magnetic assembly is strengthened, and the magnetic attraction strength between the magnetic elements of the first body 10 and the magnetic mating parts 201 of the second body 20 is further improved.

[0054] like Figure 4 As shown, the first direction A and the second direction B are perpendicular. The first magnetic element 31 and the second magnetic element 32 are arranged opposite each other along the first direction A. The third magnetic element 33 and the fourth magnetic element 34 are arranged opposite each other along the first direction A. The first magnetic element 31 and the third magnetic element 33 are arranged opposite each other along the second direction B. The second magnetic element 32 and the fourth magnetic element 34 are arranged opposite each other along the second direction B.

[0055] In other embodiments, the first body 10 may also include six, eight or more magnetic elements 3.

[0056] When the first body 10 has multiple magnetic components 3, the second body 20 can also have multiple magnetic mating components 201. The magnetic components 3 and the magnetic mating components 201 correspond one-to-one. When the first body 10 and the second body 20 are located on both sides of the part to be cleaned 30, each magnetic component 3 and the corresponding magnetic mating component 201 are magnetically attracted.

[0057] In one specific embodiment, such as Figure 3 , Figure 5As shown, the mounting mechanism 1 has a base 13 and a housing 14 that are connected to each other. The housing 14 has a hollow structure, and the magnetic component 3 is fixed on the base 13.

[0058] When the first body 10 and the second body 20 are located on both sides of the part to be cleaned 30, the base 13 is close to the part to be cleaned 30, and the magnetic part 3 is fixed on the base 13, so that the magnetic part 3 is close to the part to be cleaned 30, which makes it easy to ensure the magnetic attraction effect between the magnetic part 3 and the magnetic mating part 201.

[0059] The magnetic component 3 can be fixed on the side of the base 13 facing the outer shell 14, or the magnetic component 3 can also be fixed on the side of the base 13 away from the outer shell 14.

[0060] In one specific embodiment, such as Figures 5-6 As shown, the vacuum assembly 2 includes a fan 21 and a mounting housing 22. The mounting housing 22 has a second space 221 and an exhaust port (not shown in the figure). The exhaust port communicates with the second space 221, and the fan 21 is installed in the second space 221. The mounting housing 22 is fixed on the mounting mechanism 1, and the second space 221 of the mounting housing 22 communicates with the air inlet 12.

[0061] When the vacuum assembly 2 is working, the fan 21 is in working condition. Under the action of the fan 21, air is drawn into the second space 221 from the air inlet 12, and discharged into the first space 11 through the exhaust port, and then discharged from the first space 11 through the exhaust port.

[0062] The number of vacuum pumping components 2 can be one or more. For example Figure 6 As shown, there are two vacuum pumping components 2.

[0063] In one specific embodiment, such as Figure 1 As shown, the first body 10 also includes a cleaning component 7, which is installed at the bottom of the mounting mechanism 1.

[0064] When the first body 10 and the second body 20 are respectively located on both sides of the part to be cleaned 30, the cleaning part 7 comes into contact with the part to be cleaned 30. During the movement of the first body 10, the cleaning part 7 is driven to move relative to the part to be cleaned 30, so that the cleaning part 7 cleans the part to be cleaned 30.

[0065] Since the first body 10 is adsorbed onto the part to be cleaned 30 through both vacuum adsorption and magnetic adsorption, the adsorption effect of the first body 10 is strong, which increases the friction between the cleaning part 7 and the part to be cleaned 30, and can effectively remove stubborn stains on the part to be cleaned 30.

[0066] The cleaning component 7 can be a cleaning cloth or cleaning paper, etc.

[0067] To prevent the first body 10 from falling from the part to be cleaned 30 to below it, such as Figure 1 As shown, the mounting mechanism 1 is provided with a connecting part 15, and the first body 10 also includes a safety connector 4. One end of the safety connector 4 is connected to the connecting part 15, and the other end of the safety connector 4 is used to connect to the fixed structure.

[0068] In emergency situations such as failure of vacuum adsorption and magnetic adsorption due to improper operation, the first body 10 will not collide with the ground or other objects because the installation mechanism 1 is connected to the fixed structure through the safety connector 4, thereby reducing the risk of damage to the first body 10 due to impact.

[0069] Specifically, the safety connector 4 is a safety rope or safety belt, etc. The fixing structure can be a stable structure such as a guardrail fixed near the part to be cleaned 30.

[0070] The connecting part 15 can be equipped with a buckle, and one end of the safety connector 4 is connected to the buckle, so that the safety connector 4 can be stably connected to the buckle and can also be removed from the buckle.

[0071] In one specific embodiment, the first body 10 further includes at least one ranging mechanism 5, which is mounted on the mounting mechanism 1 and is used to detect the distance between the mounting mechanism 1 and the obstacle.

[0072] The ranging mechanism 5 can be a radar or laser rangefinder, etc.

[0073] When the first body 10 and the second body 20 are located on both sides of the part to be cleaned 30, the distance measuring mechanism 5 can detect the distance between the installation mechanism 1 and the obstacle, so that the first body 10 can avoid the obstacle during the movement, which is conducive to the first body 10 rationally planning the movement path and the first body 10 effectively cleaning the part to be cleaned 30.

[0074] Compared to simple limit switches, this embodiment uses a ranging mechanism 5, which can more accurately measure the distance to obstacles, enabling more intelligent path planning and obstacle avoidance. The cleaning process is more flexible and efficient, and can effectively avoid cleaning dead spots.

[0075] The first body 10 may include multiple ranging mechanisms 5, which are arranged circumferentially along the mounting mechanism 1.

[0076] like Figure 1 As shown, and in combination Figure 7A distance measuring mechanism 5 is installed on each side of the length direction of the mounting mechanism 1, and a distance measuring mechanism 5 is installed on each side of the width direction of the mounting mechanism 1. When the first body 10 is working, the distance measuring mechanisms 5 around the mounting mechanism 1 can measure the range of the outer frame of the part to be cleaned 30, so that the first body 10 can flexibly plan the movement path, which is conducive to improving the cleaning efficiency.

[0077] In order to enable the first body 10 to move flexibly, such as Figure 1 As shown, and in combination Figures 7-8 The first body 10 is located in a coordinate system composed of the X-axis, Y-axis and Z-axis. The first body 10 also includes a traveling component 6 mounted on the mounting mechanism 1. The traveling component 6 includes a first Mecanum wheel 61, a second Mecanum wheel 62, a third Mecanum wheel 63 and a fourth Mecanum wheel 64. The first Mecanum wheel 61 and the second Mecanum wheel 62 are symmetrically arranged about the X-axis, the third Mecanum wheel 63 and the fourth Mecanum wheel 64 are symmetrically arranged about the X-axis, the first Mecanum wheel 61 and the third Mecanum wheel 63 are symmetrically arranged about the Y-axis, and the second Mecanum wheel 62 and the fourth Mecanum wheel 64 are symmetrically arranged about the Y-axis.

[0078] The walking component 6 also includes multiple driving components 65, which are all fixed on the mounting mechanism 1. Each driving component 65 corresponds to a Mecanum wheel and is used to drive the corresponding Mecanum wheel to rotate.

[0079] When the first body 10 moves forward, the first Mecanum wheel 61, the second Mecanum wheel 62, the third Mecanum wheel 63, and the fourth Mecanum wheel 64 are all driven to rotate in the forward direction; when the first body 10 moves backward, the first Mecanum wheel 61, the second Mecanum wheel 62, the third Mecanum wheel 63, and the fourth Mecanum wheel 64 are all driven to rotate in the reverse direction; when the first body 10 rotates, only the first Mecanum wheel 61 and the second Mecanum wheel 62 can be driven to rotate simultaneously in opposite directions, or only... The first body 10 is moved laterally to the left, and the first Mecanum wheel 61 and the fourth Mecanum wheel 64 are moved in opposite directions simultaneously. When the first body 10 is moved laterally to the left, the first Mecanum wheel 61 and the fourth Mecanum wheel 64 are moved in opposite directions simultaneously, and the second Mecanum wheel 62 and the third Mecanum wheel 63 are moved in the forward direction simultaneously. When the first body 10 is moved laterally to the right, the first Mecanum wheel 61 and the fourth Mecanum wheel 64 are moved in the forward direction simultaneously, and the second Mecanum wheel 62 and the third Mecanum wheel 63 are moved in opposite directions simultaneously.

[0080] Taking the forward movement of the first body 10 as an example, the first Mecanum wheel 61, the second Mecanum wheel 62, the third Mecanum wheel 63, and the fourth Mecanum wheel 64 all rotate in the forward direction. The lateral movement forces of the first Mecanum wheel 61, the second Mecanum wheel 62, the third Mecanum wheel 63, and the fourth Mecanum wheel 64 cancel each other out, leaving only the forward movement force, which enables the first body 10 to move forward.

[0081] In this embodiment, the arrangement of the first Mecanum wheel 61, the second Mecanum wheel 62, the third Mecanum wheel 63, and the fourth Mecanum wheel 64 enables the first body 10 to move forward, backward, rotate, and laterally, thereby making the autonomous path planning of the first body 10 more flexible and efficient.

[0082] To facilitate the retrieval of the first main body 10, such as Figure 1 As shown, the mounting mechanism 1 is also equipped with a handle 9.

[0083] Specifically, such as Figure 1 As shown, the first body 10 also includes a power supply mechanism 8, which is mounted on the mounting mechanism 1 and is used to supply power to the drive unit 65, the fan 21 and the ranging mechanism 5.

[0084] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered within the scope of protection of this application.
