Cleaning robot

Abstract

The utility model discloses a cleaning robot which comprises a rack, a cleaning assembly, a driving assembly and a limiting assembly. The cleaning assembly is hinged to the rack; the driving assembly is connected with the rack; the limiting assembly is arranged on the rack and comprises a first limiting structure and a second limiting structure. According to the cleaning robot, due to the fact that the limiting assembly comprises the first limiting structure and the second limiting structure, after the cleaning assembly rotates by a certain angle in the forward direction relative to the rack, the first limiting structure can abut against the cleaning assembly so as to prevent the cleaning assembly from continuously rotating in the forward direction relative to the rack; after the cleaning assembly rotates by a certain angle in the reverse direction relative to the rack, the second limiting structure can abut against the cleaning assembly to prevent the cleaning assembly from continuing to rotate in the reverse direction relative to the rack, and therefore the limiting assembly can limit the rotating angle of the cleaning assembly relative to the rack within a certain range. The probability that the cleaning assembly interferes with other structures on the rack is reduced.

[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference below Figures 1 to 7 The cleaning robot of the present utility model is described in detail.

[0038] refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the cleaning robot includes a frame 100, a cleaning component 200, a driving component 300 and a limiting component 400.

[0039] The cleaning assembly 200 is arranged on the front side of the frame 100, and the rear end of the cleaning assembly 200 is hinged to the front end of the frame 100, so that the cleaning assembly 200 can swing up and down relative to the frame 100; the limiting assembly 400 is arranged on the frame 100, and the limiting assembly 400 includes a first limiting structure and a second limiting structure; the driving assembly 300 is connected to the frame 100, and can drive the frame 100 to connect to the cleaning assembly 200 to move forward and backward.

[0040] When the cleaning robot of this embodiment is working, the driving component 300 can drive the frame 100 together with the cleaning component 200 to move along the working surface. When the cleaning component 200 moves to the concave surface of the working surface, the cleaning component 200 can swing upward at a certain angle relative to the frame 100, so that the cleaning component 200 can always keep in contact with the working surface; when the cleaning component 200 moves to the convex surface of the working surface, the cleaning component 200 can swing downward at a certain angle relative to the frame 100, so that the cleaning component 200 can always keep in contact with the working surface.

[0041] It can be understood that when the cleaning component 200 is swung upward by a certain angle, the cleaning component 200 can abut against the first limiting structure. At this time, the first limiting structure can prevent the cleaning component 200 from continuing to swing upward relative to the frame 100; when the cleaning component 200 is swung downward by a certain angle, the cleaning component 200 can abut against the second limiting structure. At this time, the second limiting structure can prevent the cleaning component 200 from continuing to swing downward relative to the frame 100.

[0042] Furthermore, the setting of the first limiting structure and the second limiting structure enables the swing of the cleaning component 200 in the vertical direction relative to the frame 100 to be limited within a certain angle range, so as to avoid the cleaning component 200 from swinging too much upward or downward relative to the frame 100, which may cause the cleaning component 200 to interfere with other structures on the frame 100, thereby extending the service life of the cleaning robot of the present application.

[0043] In a specific embodiment of the present invention, reference Figure 2 and Figure 3 The limiting assembly 400 includes a limiting member 410, which is located on the upper side of the hinged connection between the cleaning assembly 200 and the frame 100. The lower end of the limiting member 410 is formed with a first abutting surface 411 and a second abutting surface 412. The first abutting surface 411 is located in front of the second abutting surface 412, and the first abutting surface 411 is an inclined surface that gradually extends upward from the front end, and the second abutting surface 412 is an inclined surface that gradually extends upward from the rear end. The first abutting surface 411 constitutes a first limiting structure, and the second abutting surface 412 constitutes a second limiting structure.

[0044] Furthermore, when the cleaning component 200 is swung upward at a certain angle relative to the frame 100, the cleaning component 200 can abut against the first abutment surface 411. At this time, the first abutment surface 411 prevents the cleaning component 200 from continuing to swing upward; when the cleaning component 200 is swung downward at a certain angle relative to the frame 100, the cleaning component 200 can abut against the second abutment surface 412. At this time, the second abutment surface 412 prevents the cleaning component 200 from continuing to swing upward.

[0045] It is understandable that the staff can control the maximum upward swing amplitude of the cleaning component 200 relative to the frame 100 by changing the inclination angle of the first abutment surface 411; the staff can control the maximum downward swing amplitude of the cleaning component 200 relative to the frame 100 by changing the inclination angle of the second abutment surface 412.

[0046] In some embodiments of the present invention, reference Figure 4 and Figure 5 The cleaning assembly 200 includes a connecting member 210, which is hinged to the frame 100; a third abutting surface 211 and a fourth abutting surface 212 are formed on the connecting member 210, the third abutting surface 211 is located on the lower side of the first abutting surface 411, and the fourth abutting surface 212 is located on the lower side of the second abutting surface 412.

[0047] In the cleaning robot of the present embodiment, after the cleaning component 200 is swung upward at a certain angle relative to the frame 100, the third abutment surface 211 can be fitted with the first abutment surface 411. At this time, the first abutment surface 411 can prevent the cleaning component 200 from continuing to swing upward relative to the frame 100; after the cleaning component 200 is swung downward at a certain angle relative to the frame 100, the fourth abutment surface 212 can be fitted with the second abutment surface 412. At this time, the second abutment surface 412 can prevent the cleaning component 200 from continuing to swing downward relative to the frame 100.

[0048] Specifically, refer to Figure 2 and Figure 5 In order to realize the hinge between the connecting member 210 and the frame 100, a first hinge hole 214 is provided on the connecting member 210, a second hinge hole is provided on the frame 100, the hinge shaft 120 passes through the first hinge hole 214 and the second hinge hole, and a copper sleeve is provided between the hinge shaft 120 and the second hinge hole.

[0049] In a further embodiment of the present invention, in order to simplify the structure of the connecting member 210 , the third abutting surface 211 and the fourth abutting surface 212 are located on the same plane.

[0050] It should be noted that, during the operation of the cleaning robot, there is a problem that the connecting member 210 moves relative to the frame 100 in the horizontal direction.

[0051] Based on the above problem, in some embodiments of the present invention, the cleaning robot further includes a guiding structure, and the guiding structure is disposed on the frame 100 .

[0052] Furthermore, the guide structure can guide the cleaning assembly 200 to rotate up and down relative to the frame 100, so as to reduce the probability of the connection member 210 moving relative to the frame 100 in the horizontal direction.

[0053] In a specific embodiment of the present invention, reference Figure 2 and Figure 5 The guide structure includes a bolt 110 , and an arc-shaped hole 213 is provided on the connecting member 210 . The bolt 110 can be slidably penetrated in the arc-shaped hole 213 and connected to the frame 100 .

[0054] Furthermore, when the cleaning assembly 200 swings up and down relative to the frame 100 , the connecting member 210 can swing up and down relative to the bolt 110 , and in this process, the hole wall of the arc hole 213 can limit the bolt 110 .

[0055] In other embodiments of the present invention, the guide structure may further include a protrusion. In this case, the protrusion is integrally formed with the frame 100 , and the protrusion is slidably inserted into the arc hole 213 of the connecting member 210 .

[0056] In some embodiments of the present invention, in order to improve the stability of the connection between the cleaning assembly 200 and the frame 100, a plurality of connecting members 210 are provided, and correspondingly, a plurality of groups of first abutting surfaces 411 and second abutting surfaces 412 corresponding to the connecting member 210 are provided on the limiting member 410.

[0057] In the figure, a cleaning assembly 200 including two connecting members 210 is taken as an example for description.

[0058] In some embodiments of the present invention, reference Figure 1 The driving assembly 300 includes two drivers 310 and two driving wheels 320. The two driving wheels 320 are rotatably disposed on the frame 100 and are arranged side by side in the left-right direction. The driver 310 is disposed on the frame 100. The driver 310 corresponds to and is connected to the driving wheels 320 one by one. The driver 310 can independently drive the connected driving wheels 320 to rotate.

[0059] It can be understood that since the two driving wheels 320 are each driven separately by a driver 310,

[0060] Furthermore, the rotation speed difference between the two driving wheels 320 can be adjusted through the two drivers 310, so that the forward direction of the cleaning robot of this embodiment can be controlled.

[0061] In a further embodiment of the present invention, reference Figure 1 The driving assembly 300 further includes two auxiliary wheels 330 , which are disposed at the rear side of the driving wheel 320 , and the two auxiliary wheels 330 are disposed side by side on the frame 100 along the left-right direction.

[0062] It can be understood that by providing two auxiliary wheels 330 , the stability of the cleaning robot of this embodiment during movement can be improved.

[0063] It should be noted that when the cleaning robot of the present application is working, the working surface may be a vertical inclined surface.

[0064] In order to enable the cleaning robot of the present application to firmly adhere to the vertical inclined plane during operation, in some embodiments of the present invention, the cleaning robot further includes an adsorption component 500 , which is disposed on the frame 100 .

[0065] Furthermore, the adsorption component 500 can provide an adsorption force to keep the cleaning robot in contact with the working surface, so that the driving wheel 320 can be firmly attached to the working surface, and thus, under the drive of the driver 310, the cleaning robot of this embodiment can walk on a vertical inclined plane.

[0066] It should be noted that the cleaning robot of the present application is generally used to clean the surface of a ship, and the material of the ship surface includes ferroalloy.

[0067] In a further embodiment of the present invention, reference Figure 1 and Figure 7 The adsorption component 500 includes a first magnetic adsorption structure 510 with magnetism. The first magnetic adsorption structure 510 is arranged on the frame 100 and is located between the two driving wheels 320. The first magnetic adsorption structure 510 includes a shell 511 and a plurality of magnets 512. The front and rear edges of the lower end of the shell 511 are both provided with an avoidance slope 511a. The plurality of magnets 512 are accommodated in the shell 511 along the left and right directions, and the front and rear edges of the lower end of the magnet 512 are both provided with an adsorption slope matched with the avoidance slope 511a.

[0068] It can be understood that by setting the first magnetic adsorption structure 510 between the two driving wheels 320,

[0069] Under the action of the adsorption force of the first magnetic adsorption structure 510 on the working surface, the driving wheel 320 can be closely attached to the working surface, so that the cleaning robot of this embodiment can walk stably on the working surface, thereby reducing the probability of the cleaning robot of this embodiment falling from the working surface.

[0070] It can be understood that the setting of the avoidance slope 511a can reduce the probability of interference between the shell 511 and the working surface when the cleaning robot of this embodiment passes through a concave working surface; at the same time, the setting of the adsorption slope on the magnet 512 can make the two avoidance slopes 511a on the shell 511 have a strong magnetic attraction, so that the cleaning robot of this embodiment can pass through the concave working surface smoothly.

[0071] In a further embodiment of the present invention, reference Figure 1 The adsorption assembly 500 further includes a second magnetic adsorption structure 520 having magnetism. The second magnetic adsorption structure 520 is disposed on the frame 100 and is located between the two auxiliary wheels 330 .

[0072] It is understandable that by arranging the second magnetic adsorption structure 520 between the two auxiliary wheels 330, under the action of the adsorption force of the second magnetic adsorption structure 520 on the working surface, the auxiliary wheels 330 can be closely attached to the working surface, so that the cleaning robot of this embodiment can walk stably on the working surface.

[0073] The specific structure of the second magnetic adsorption structure 520 refers to the first magnetic adsorption structure 510 .

[0074] In some embodiments of the present invention, reference Figure 4 The cleaning assembly 200 also includes a cleaning disc 220, a brush structure 230 and an elastic connecting member 240. The brush structure 230 includes an annular movable member 231 and annular bristles 232. The annular movable member 231 is movably arranged at the lower end edge of the cleaning disc 220 along the vertical direction. The annular bristles 232 are arranged on the annular movable member 231. The upper and lower ends of the elastic connecting member 240 are respectively connected to the cleaning disc 220 and the annular movable member 231.

[0075] It can be understood that by providing an elastic connecting member 240, when the working surface is uneven, the brush structure 230 can float relative to the working surface under the elastic force of the elastic connecting member 240 to move closer to or away from the working surface, so that when the working surface is uneven, the brush structure 230 can still move smoothly along the working surface.

[0076] In a further embodiment of the present invention, reference Figure 5 The elastic connecting member 240 is a spring. The cleaning assembly 200 further includes a plurality of guide rods 250 . The guide rods 250 are extended in a vertical direction and are disposed on the cleaning disc 220 . The springs are sleeved on the guide rods 250 in a one-to-one correspondence.

[0077] It can be understood that, under the guiding action of the guide rod 250, the spring can accurately extend or contract in the vertical direction, so that the brush structure 230 can accurately extend or contract in the vertical direction.

[0078] In a further embodiment of the present invention, in order to improve the cleaning effect of the cleaning assembly 200, reference is made to Figure 6 A water outlet 221 and a water pumping port 222 are provided in the cleaning plate 220. The water outlet 221 is connected to a water pump. Under the action of the water pump, the water outlet 221 can spray out a high-pressure water flow to flush the working surface. The water pumping port 222 is connected to a water pump. Under the action of the water pump, sewage can be pumped out from the water pumping port 222.

[0079] In a further embodiment of the present invention, reference Figure 4 The cleaning assembly 200 also includes two transition wheel structures 260 , which include a mounting frame 261 and a universal wheel 262 . The universal wheel 262 is rotatably disposed on the mounting frame 261 and is located at the front side of the cleaning disc 220 . The mounting frame 261 is disposed on the cleaning disc 220 .

[0080] It can be understood that, by providing the transition wheel structure 260, when the cleaning robot of this embodiment encounters another working surface during the forward movement, the universal wheel 262 can first abut against the other working surface and guide the cleaning robot to crawl onto the other working surface.

[0081] It should be noted that during the operation of the cleaning robot, the cleaning robot may collide with obstacles. In this case, the cleaning robot is prone to damage.

[0082] In order to reduce the damage to the cleaning robot after the cleaning robot collides with an obstacle, in some embodiments of the present utility model, reference Figure 1 The cleaning robot also includes an anti-collision component 600, which includes a first anti-collision rod 610 and a second anti-collision rod 620. The first anti-collision rod 610 is arranged at the front end of the cleaning component 200, and the second anti-collision rod 620 is arranged at the rear end of the frame 100.

[0083] It can be understood that by setting the first anti-collision bar 610, when there is an obstacle at the front end of the cleaning robot of this embodiment, the first anti-collision bar 610 can be the first to contact the obstacle when the cleaning robot is moving forward, so as to protect other structures on the cleaning robot; by setting the second anti-collision bar 620, when there is an obstacle at the rear end of the cleaning robot of this embodiment, the second anti-collision bar 620 can be the first to contact the obstacle when the cleaning robot is moving backward, so as to protect other structures on the cleaning robot.

[0084] It can be understood that the first anti-collision bar 610 and the second anti-collision bar 620 are set separately, which can reduce the overall height of the cleaning robot of this embodiment compared to the first anti-collision bar 610 and the second anti-collision bar 620 being set in a homogeneous and integrated manner, making the structure of the cleaning robot of this embodiment more miniaturized.

[0085] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
