Description

Technical Field

[0001] This utility model relates to the field of track technology, specifically to a track and cleaning robot. Background Technology

[0002] For example, the suction cup track drive mechanism and photovoltaic panel cleaning robot disclosed in Chinese Patent Publication No. CNCN215198810U can create a vacuum area by the suction cup being deformed by the extrusion roller during the track's rotation, generating a certain suction force that allows the suction cup to contact and adhere to the surface. However, the track in this patent has poor drainage capacity when washed, resulting in moisture between the suction cup and the surface, leading to unstable adhesion and reduced friction. When the photovoltaic panel is tilted at too high an angle, the cleaning robot may slip and fall, posing a significant safety risk. Furthermore, the track structure is complex, has high manufacturing costs, and increases the probability of mechanical failure. Utility Model Content

[0003] The present invention aims to provide a track to solve the aforementioned technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a track, including a main track and multiple support units, the multiple support units are arranged at intervals on the outer surface of the main track, the surface of the support unit is provided with a mesh channel and multiple anti-slip blocks, the mesh channel separates the multiple anti-slip blocks from each other, and the surface of the anti-slip blocks is provided with a drainage channel communicating with the mesh channel.

[0005] Preferably, the mesh channel is a honeycomb mesh channel, and the anti-slip block is a regular hexagon.

[0006] Preferably, the drainage channel is a Y-shaped drainage channel.

[0007] Preferably, the depth and width of the mesh channel are greater than the depth and width of the drainage channel, respectively.

[0008] Preferably, multiple support units are arranged at intervals along the front-to-back direction on the outer surface of the main belt, and an elastic telescopic body connects the support units to the outer surface of the main belt, with a buffer channel running through the elastic telescopic body.

[0009] Preferably, the elastic stretching body is a soft gel-like elastic stretching body.

[0010] Preferably, there are multiple buffer channels arranged side by side, and the elastic expansion body between two adjacent buffer channels is V-shaped.

[0011] Preferably, the inner surface of the main belt is uniformly provided with meshing teeth for meshing with the pulley.

[0012] This utility model also provides a cleaning robot, including any of the tracks described above.

[0013] This utility model has the following beneficial effects:

[0014] By using multiple support units spaced apart on the outer surface of the main track, each support unit's anti-slip blocks are independently separated by mesh channels, ensuring the track won't crack due to excessive thickness. The mesh channels are interconnected with drainage channels, enhancing the track's drainage capacity and increasing the friction of the anti-slip blocks. This allows for stable adhesion to the photovoltaic panel surface, reducing the risk of slippage and falls for the cleaning robot, and improving its climbing angle, meeting the needs of cleaning robots in complex working environments. Furthermore, the track's simple structure and low manufacturing cost reduce the probability of mechanical failures. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] See Figure 1-6 As shown, as an embodiment of the present utility model, a track is provided, including a main track 1 and a plurality of support units 2. The plurality of support units 2 are arranged at intervals on the outer surface of the main track 1. The surface of the support unit 2 is provided with a mesh channel 22 and a plurality of anti-slip blocks 21. The mesh channel 22 separates the plurality of anti-slip blocks 21 from each other. The surface of the anti-slip blocks 21 is provided with a drainage channel 23 that communicates with the mesh channel 22. This track is primarily used on the pulleys of cleaning robots in the field of photovoltaic panel cleaning. During the water washing and cleaning of photovoltaic panels, the support units 2 on the outer surface of the main track 1 are spaced apart. The anti-slip blocks 21 on each support unit 2 are separated from each other by mesh channels 22 to ensure that the track will not crack due to excessive thickness. The mesh channels 22 are interconnected with the drainage channels 23, which can improve the drainage capacity of the track and increase the friction of the anti-slip blocks 21, thereby ensuring stable adhesion to the photovoltaic panel surface, reducing the risk of slippage and falls of the cleaning robot, and improving the tilt angle of the cleaning robot when climbing slopes, meeting the usage requirements of the cleaning robot in complex working environments. Moreover, the track has a simple structure, low manufacturing cost, and reduces the probability of mechanical failure.

[0026] In this embodiment, the depth and width of the mesh channel 22 are greater than the depth and width of the drainage channel 23, respectively. The mesh channel 22 is a honeycomb mesh channel, the anti-slip block 21 is hexagonal, and the drainage channel 23 is a Y-shaped drainage channel. The Y-shaped channel divides the anti-slip block 21 into three rhomboid blocks of equal area. This structural design makes the friction and drainage capacity of the support unit 2 more balanced and stable at different positions. The Y-shaped channel directs water flow to the left and right sides towards the mesh channel 22, and then discharges it to the outside through the mesh channel 22, resulting in faster drainage efficiency and better drainage effect, thereby improving the friction of the track. In addition, when encountering obstacles, the three rhomboid blocks can elastically open in a direction away from each other, further preventing the anti-slip block 21 from being too thick and causing cracking, thus improving applicability and extending the service life of the track.

[0027] In this embodiment, multiple support units 2 are arranged at intervals along the front-back direction on the outer surface of the main body belt 1, and an elastic telescopic body 3 is connected between the support units 2 and the outer surface of the main body belt 1. The elastic telescopic body 3 is provided with a buffer channel 4 that runs through the left and right sides. This structure allows the support units 2 to be squeezed inward and elastically contracted when the cleaning robot crosses irregular obstacles and photovoltaic panel frames, ensuring that the contact area between the track surface and the photovoltaic panel changes little, preventing the cleaning robot from slipping when crossing obstacles. After crossing the obstacle, the track then moves back to its original position according to its own deformation characteristics, thereby improving the track's obstacle-crossing ability and making it more applicable, thus meeting the needs of use in complex working environments.

[0028] In this embodiment, the elastic stretching body 3 is a soft rubber elastic stretching body, and there are three buffer channels 4 arranged side by side, with the elastic stretching body 3 between two adjacent buffer channels 4 forming a V-shaped plate, which provides good elasticity and ensures that the support unit 2 can be stably reset. Of course, in other cases, there may be other numbers of buffer channels 4, which is not limited here.

[0029] In this embodiment, the inner side surface of the main belt 1 is uniformly provided with meshing teeth 5, which mesh with the pulley and drive the track to rotate and move through the pulley.

[0030] This utility model also provides a cleaning robot, including the track described in the above embodiments. The track is mounted on the pulleys of the cleaning robot. The track of this cleaning robot has good drainage capacity and friction, thus enabling it to adhere stably to the photovoltaic panel. This improves the stability of the cleaning robot when walking under wet conditions, reduces the risk of slipping and falling, and increases the tilt angle for climbing slopes, meeting the usage requirements of the cleaning robot in complex working environments. Furthermore, the track has a simple structure, low manufacturing cost, and reduces the probability of mechanical failure.

[0031] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
