[0003] Existing solar panels are cleaned by robots. There are gaps between adjacent solar panels. When the robot passes by adjacent solar panels, it will generate a certain vibration, which is easy to cause the panel surface to jump, reducing the cleaning efficiency. At the same time, there is also a risk of the robot falling.

[0004] In order to solve the above technical problems, the existing technology provides a buffering and shock-absorbing wheel hub, including: a rim, a spoke and a hub, the rim is coaxially arranged on the outside of the hub, the spokes are fixedly connected to the rim and the hub, and the hub includes an inner boss, an outer boss and a connecting ring. Although it solves the problem of robot vibration to a certain extent, it uses a crawler form when walking on the solar panel, the assembly is cumbersome, and the shock-absorbing effect is not obvious. When the robot passes by the stains on the surface of the solar panel, a certain gap is generated between the wheel group and the solar panel, causing stains to remain on the surface of the solar panel.

[0005] In summary, a new shock-absorbing wheel for a cleaning robot is urgently needed to solve the problem that the existing shock-absorbing wheel is too hard and has an insignificant shock-absorbing effect, which makes it easy for the panel surface to bounce during cleaning of the solar panel.

[0022] The new shock-absorbing wheel provided by the embodiment of the utility model has a rubber layer inside the rubber wheel, which can absorb the vibration generated by the shock-absorbing wheel when the shock-absorbing wheel passes through a smaller gap. At the same time, a shock-absorbing main body is provided, and the shock-absorbing main body is set as a sheet structure with a certain arc.

[0023] Example 1

[0024] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a novel damping wheel 100, comprising: a rotating shaft body 110, wherein the middle portion of the rotating shaft body 110 is provided with an embedded hole, a bearing is embedded in the embedded hole, and a driving shaft is embedded in the bearing;

[0025] The shock absorbing body 130 has one end connected to the shaft body 110 and the other end connected to the rubber wheel 120. The shock absorbing body 130 is composed of a plurality of shock absorbing sheets, and the cross-sectional shape of the shock absorbing sheet has a certain curvature.

[0026] The rubber wheel 120 is provided with a wear-resistant layer 121, a rubber layer and a connecting layer 122. The connecting layer 122 is arranged on the inner side of the rubber layer, and the wear-resistant layer 121 is arranged on the outside of the rubber layer. The wear-resistant layer 121, the rubber layer and the connecting layer 122 are fixedly connected by gluing.

[0027] The shock-absorbing wheels 100 of the solar panel cleaning robot are mainly used to reduce the impact and vibration of the robot on the solar panel during the cleaning process. By providing the shock-absorbing wheels 100 in the solar cleaning robot, it helps to protect the solar panel and avoid damage due to excessive impact. In order to solve the problem that the existing shock-absorbing wheels 100 are too hard and the shock-absorbing effect is not obvious, this embodiment provides a new shock-absorbing wheel 100.

[0028] In one embodiment, the shaft body 110 is used to connect the driving shaft of the cleaning robot. The material of the shaft body 110 can be metal, such as alloy steel, or non-metallic material, such as plastic. In this embodiment, plastic is preferred, and the specific material can be selected according to actual needs.

[0029] An embedded hole is provided in the middle of the rotating shaft body 110. The size of the embedded hole can be adjusted according to the outer diameter of the bearing. A bearing is embedded in the embedded hole, and a drive shaft is embedded in the bearing. The drive shaft can be connected to the embedded hole through the bearing.

[0030] In another embodiment, the shock-absorbing body 130 is used for shock absorption of a photovoltaic panel cleaning robot. When the shock-absorbing wheel 100 passes through the connection between adjacent solar photovoltaic panels, vibration is generated. The shock-absorbing body 130 is used to absorb the vibration generated by the shock-absorbing wheel 100. The shock-absorbing body 130 can be a shock-absorbing rubber pad or a shock-absorbing wheel 100 provided with a shock-absorbing fluid. The material of the shock-absorbing body 130 can be plastic, rubber, or fluid. The specific material can be selected according to actual needs. The shape of the shock-absorbing body 130 can be sheet-shaped, long strip-shaped, or solid circular. The specific shape can be selected according to actual needs. In this embodiment, the shock-absorbing body 130 is preferably made of rubber and has a sheet-shaped shape.

[0031] Specifically, one end of the shock-absorbing body 130 is connected to the rotating shaft body 110, and the other end is connected to the rubber wheel 120. The shock-absorbing body 130 is composed of multiple shock-absorbing plates. The interface shape of the shock-absorbing plate has a certain curvature. It should be noted that the value of the curvature can be adjusted according to actual needs. Specifically, the value of the curvature can be 10 degrees, 20 degrees, 30 degrees or 40 degrees. In this embodiment, the shock-absorbing plate is set to a certain curvature. When the shock-absorbing wheel 100 vibrates, the arc-shaped shock-absorbing plate can produce a certain deformation, thereby absorbing the vibration of the shock-absorbing wheel 100 and achieving a shock-absorbing effect.

[0032] In another embodiment, the rubber wheel 120 is arranged at the outermost side of the shock-absorbing wheel 100, and the rubber wheel 120 is used to contact the solar panel. The rubber wheel 120 is provided with a wear-resistant layer 121, a rubber layer and a connecting layer 122. The connecting layer 122 is arranged on the inner side of the rubber wheel, and the connecting layer 122 is used to connect the shock-absorbing body 130 and the rubber layer. The wear-resistant layer 121 is arranged outside the rubber layer, and the wear-resistant layer 121 is used to contact the solar panel. The rubber layer is used to absorb the vibration generated by the shock-absorbing wheel 100, and the wear-resistant layer 121, the rubber layer and the connecting layer 122 are fixedly connected by gluing.

[0033] When the damping wheel 100 passes through adjacent solar panels, the wear-resistant layer 121 of the damping wheel 100 will pass through the connecting seams between the adjacent solar panels. The rubber layer of the damping wheel 100 absorbs the vibration transmitted by the wear-resistant layer 121, thereby reducing the vibration of the damping wheel 100. When the damping wheel 100 passes through a wider gap, the damping body 130 inside the damping wheel 100 will deform, absorbing most of the vibration of the damping wheel 100, thereby allowing the damping wheel 100 to pass smoothly through the adjacent solar photovoltaic panels.

[0034] In this embodiment, by providing a rubber layer inside the rubber wheel 120, the vibration generated by the shock-absorbing wheel 100 can be absorbed when the shock-absorbing wheel 100 passes through a smaller gap. At the same time, a shock-absorbing body 130 is provided. The shock-absorbing body 130 is set to a sheet structure with a certain arc shape. When the shock-absorbing wheel 100 passes through a larger gap, the shock-absorbing body 130 can produce a certain deformation, thereby achieving the effect of shock absorption and buffering.

[0037] In this embodiment, a connecting groove 111 is provided in the middle of the rotating shaft body 110. The connecting groove 111 is used to connect the driving shaft. The shape of the connecting groove 111 can be adjusted according to the shape of the driving shaft. A connecting pin hole is fixed in the connecting groove 111. The connecting pin hole is used to fix the pin key. The driving shaft is embedded in the connecting groove 111, and the pin key is embedded in the connecting pin hole to realize the vibration of the driving shaft and the damping wheel 100.

[0038] The damping wheel 100 and the driving shaft are connected by an embedded connecting pin, which can effectively reduce vibration and enhance stability. At the same time, the fixed connection by a pin key can ensure smoother force transmission and improve transmission efficiency.

[0039] Example 3

[0040] like Figure 2 In the embodiment shown, a T-shaped positioning groove 112 is provided in the connecting groove 111 .

[0041] In this embodiment, a T-shaped positioning groove 112 is provided in the connecting groove 111. The T-shaped positioning groove 112 is used to position the drive shaft. It is easy to understand that a positioning key corresponding to the T-shaped groove is provided on the drive shaft. The positioning key on the drive shaft is embedded in the T-shaped positioning groove 112 to realize the positioning of the drive shaft and the shock-absorbing wheel 100. By providing the T-shaped positioning groove 112, the assembly of the drive shaft and the shock-absorbing wheel 100 can be made more accurate and efficient, thereby ensuring the smooth operation of the shock-absorbing wheel 100.
