[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] Please refer to the attached document. Figures 1-5 This application provides a roller brush shock absorption component 100, which is applied to a photovoltaic cleaning robot and is used to reduce the noise of the movable support 21 during the falling process.

[0036] Please refer to the attached document. Figures 1-5 In this embodiment, the roller brush shock absorption assembly 100 includes a robot body 10 and a roller brush module 20; the roller brush module 20 includes a movable support 21, a shock absorber 22, and a roller brush 23; the roller brush 23 is rotatably connected to the movable support 21; the movable support 21 is movably connected to the robot body 10 and can move up and down relative to the robot body 10; the shock absorber 22 is disposed between the robot body 10 and the movable support 21, and the shock absorber 22 is provided with a first shock absorber arm 221, which elastically contacts the movable support 21 and applies an elastic force to the movable support 21 to reduce the noise of the movable support 21 during the falling process. By fully utilizing the elastic support of the first shock absorber arm 221 on the movable support 21, the falling speed of the movable support 21 is reduced, thereby reducing the noise of the movable support 21 during the falling process and avoiding the generation of large noise when the movable support 21 falls relative to the robot body 10, thus reducing the falling noise of the roller brush shock absorption assembly 100.

[0037] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the robot body 10 serves as a support component of the roller brush shock absorption assembly 100, and the robot body 10 is used to support the roller brush module 20.

[0038] The roller brush module 20 includes a movable support 21, a shock absorber 22, and a roller brush 23. The roller brush 23 is rotatably connected to the movable support 21 to adjust its position relative to the movable support 21, thereby facilitating the roller brush 23's rolling relative to the photovoltaic panel. The movable support 21 is movably connected to the robot body 10 and can move up and down relative to the robot body 10 to adjust its vertical position relative to the robot body 10, thus facilitating the roller brush module 20's movement relative to the robot body 10 via the movable support 21. Optionally, the roller brush 23 rotates relative to the movable support 21 via a rotating shaft.

[0039] The shock absorber 22 is disposed between the robot body 10 and the movable support 21. The shock absorber 22 has a first shock absorber arm 221, which elastically contacts the movable support 21 and applies an elastic force to the movable support 21 to reduce the noise of the movable support 21 during its descent. By fully utilizing the elastic support of the first shock absorber arm 221 on the movable support 21, the descent speed of the movable support 21 is reduced, thereby reducing the noise of the movable support 21 during its descent. This avoids generating excessive noise when the movable support 21 falls relative to the robot body 10, reduces the falling noise of the roller brush shock absorber assembly 100, and reduces the downward impact force of the roller brush 23 on the photovoltaic panel. At the same time, it reduces the bounce amplitude of the movable support 21 when the robot crosses obstacles, ensures the vertical movement of the roller brush 23, reduces the downward impact force of the roller brush 23 on the photovoltaic panel, and reduces the traction force required by the robot body 10 on the roller brush during movement.

[0040] Please refer to the attached document. Figures 1-3 In this embodiment of the application, the robot body 10 includes a robot housing 11, which supports a movable support 21; so that the robot housing 11 and the movable support 21 can be directly connected, thereby facilitating the robot body 10 to be directly connected to the movable support 21 through the robot housing 11, and ensuring the position of the movable support 21 relative to the robot body 10.

[0041] Alternatively, the robot body 10 includes a robot housing 11 and a support member. The support member is connected to the robot housing 11 and supports the movable bracket 21, so that the robot housing 11 can be indirectly connected to the movable bracket 21 through the support member. This facilitates the indirect connection between the robot body 10 and the movable bracket 21 through the robot housing 11, ensuring the position of the movable bracket 21 relative to the robot body 10.

[0042] Please refer to the attached document. Figures 1-3In this embodiment, the movable support 21 is swayably connected to the robot body 10 and swings in the vertical direction to adjust the vertical position of the movable support 21 relative to the robot body 10. When the roller brush 23 contacts an object on the photovoltaic panel, it lifts the movable support 21 upwards. This allows the roller brush 23 to move the movable support 21 vertically due to the uneven surface of the photovoltaic panel during its rolling process. This facilitates the application of an elastic force by the shock absorber 22 to the movable support 21, thereby reducing the noise of the movable support 21 during its descent. By fully utilizing the elastic support of the first shock absorber arm 221 on the movable support 21, the descent speed of the movable support 21 is reduced, thus reducing the noise of the movable support 21 during its descent. This avoids generating excessive noise when the movable support 21 falls relative to the robot body 10, and reduces the falling noise of the roller brush shock absorber assembly 100.

[0043] Please refer to the attached document. Figures 1-4 In this embodiment, the robot body 10 is provided with a first arm 12; a movable bracket 21 is hinged to the robot body 10 so that the movable bracket 21 can move along the axis of the connection between the movable bracket 21 and the robot body 10, and the movable bracket 21 can move closer to or further away from the first arm 12 so that the movable bracket 21 can connect to or detach from the first arm 12, thereby facilitating the movable bracket 21 to move in the vertical direction. A shock absorber 22 is connected to the first arm 12 so that the shock absorber 22 is fixed to the first arm 12, thereby facilitating the first arm 12 to limit the position of the shock absorber 22. The first shock absorber arm 221 contacts the movable bracket 21 so that the first shock absorber arm 221 applies an elastic force to the movable bracket 21 to reduce the noise of the movable bracket 21 during the falling process. By making full use of the elastic support of the first shock absorber arm 221 on the movable bracket 21, the falling speed of the movable bracket 21 is reduced, thereby reducing the noise of the movable bracket 21 during the falling process.

[0044] Please refer to the attached document. Figures 1-5 In this embodiment, the shock absorber 22 is a torsion spring. The shock absorber 22 is sleeved on the first support arm 12 so that the first shock absorber arm 221 faces the movable support 21 and elastically contacts the movable support 21. This allows the first shock absorber arm 221 to apply an elastic force to the movable support 21, thereby reducing the noise of the movable support 21 during its descent. By fully utilizing the elastic support of the first shock absorber arm 221 on the movable support 21, the descent speed of the movable support 21 is reduced, thus reducing the noise of the movable support 21 during its descent.

[0045] Please refer to the attached document. Figures 4-5In this embodiment of the application, the shock absorber 22 is further provided with a second shock absorber arm 222. The second shock absorber arm 222 is located on the other side of the first shock absorber arm 221. The second shock absorber arm 222 is connected to the first arm 12 so that the first arm 12 can restrict the position of the shock absorber 22 through the second shock absorber arm 222, thus ensuring the position of the shock absorber 22 relative to the first arm 12.

[0046] Please refer to the attached document. Figures 4-5 In this embodiment, the first support arm 12 is provided with a plurality of through holes 12a, which are arranged circumferentially along the axial direction of the first support arm 12. Each through hole 12a can be inserted into the second shock-absorbing support arm 222, so that the second shock-absorbing support arm 222 can adjust the magnitude of the elastic force applied by the first shock-absorbing support arm 221 relative to the movable bracket 21 by inserting different through holes 12a, thereby improving the versatility of the shock absorber 22.

[0047] Please refer to the attached document. Figures 1-3 In this embodiment, the robot body 10 is further provided with a second arm 13, which is located below the first arm 12; one end of the movable bracket 21 is hinged to the second arm 13 so that the second arm 13 can further abut against the position of the movable bracket 21, ensuring the connection stability of the movable bracket 21 relative to the robot body 10. The movable bracket 21 can be detached from the second arm 13 so that the movable bracket 21 can move relative to the robot body 10.

[0048] Please refer to the attached document. Figures 1-3 In this embodiment of the application, one end of the movable bracket 21 is provided with a groove 21a, which is adapted to the second support arm 13. The groove 21a has an opening for the second support arm 13 to pass through, so that the second support arm 13 can be accommodated in the groove 21a through the opening, thereby facilitating the movable bracket 21 to engage with the second support arm 13 through the groove 21a. At the same time, the movable bracket 21 can be disengaged from the second support arm 13 through the opening.

[0049] In a second embodiment of the application, a photovoltaic cleaning robot includes a roller brush shock absorption assembly 100, which is part of the photovoltaic cleaning robot used to clean photovoltaic panels.

[0050] At this time, the roller brush shock absorption assembly 100 includes a robot body 10 and a roller brush module 20; the roller brush module 20 includes a movable support 21, a shock absorber 22, and a roller brush 23; the roller brush 23 is rotatably connected to the movable support 21; the movable support 21 is movably connected to the robot body 10 and can move up and down relative to the robot body 10; the shock absorber 22 is disposed between the robot body 10 and the movable support 21, and the shock absorber 22 is provided with a first shock absorber arm 221, which elastically contacts the movable support 21 and applies an elastic force to the movable support 21 to reduce the noise of the movable support 21 during the falling process. By making full use of the elastic support of the first shock absorber arm 221 on the movable support 21, the falling speed of the movable support 21 is reduced, thereby reducing the noise of the movable support 21 during the falling process and avoiding the generation of large noise when the movable support 21 falls relative to the robot body 10, thus reducing the falling noise of the roller brush shock absorption assembly 100.
