[0065] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component. When a component is considered to be "fixed to" another component, it may be directly fixed to the other component or there may be a central component.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0068] See also Figures 1 to 16 The present invention provides a foldable photovoltaic assembly 100 that is easy to clean, comprising a first base 10, a second base 20, a first solar panel 30, a second solar panel 40, a third solar panel 50, a first drive assembly 60, a second drive assembly 70, a cleaning assembly 80, and a hydraulic assembly 90. The first base 10 is fixedly mounted on the ground or a platform, the second base 20 is located on one side of the first base 10, the first solar panel 30 is disposed on the upper surface of the first base 10, the second solar panel 40 and the third solar panel 50 are respectively disposed on both sides of the first solar panel 30 and are rotatable relative to the first base 10, the first drive assembly 60, the second drive assembly 70, and the cleaning assembly 80 are disposed on the second base 20, and the hydraulic assembly 90 connects the first drive assembly 60 and the second drive assembly 70 and is in communication with the cleaning assembly 80. When the first driving assembly 60 and the second driving assembly 70 respectively drive the second solar panel 40 and the third solar panel 50 to rotate, they can simultaneously drive the cleaning assembly 80 to slide relative to the second base 20 through the hydraulic assembly, and then the cleaning assembly 80 cleans the first solar panel 30, the second solar panel 40 and the third solar panel 50 in a translational manner, keeping the surface of the solar panel clean, preventing dust from accumulating and affecting photovoltaic power generation, and facilitating the normal operation of photovoltaic power generation.

[0069] The foldable photovoltaic assembly 100 further includes a housing 15 , which covers the various components, thereby preventing the transmission components from being easily damaged due to exposure, thereby facilitating long-term use.

[0070] like Figure 4 and Figure 5As shown, the first driving assembly 60 includes a first motor 61, a first shifting member 62, a first transmission member 63, and a first gear 64. The first motor 61 is fixedly mounted on the second base 20, and the first shifting member 62 is fixedly mounted on the output end of the first motor 61, so that when the output end of the first motor 61 rotates, the first shifting member 62 can be driven to rotate together. The first transmission member 63 is slidably mounted on the second base 20. The first transmission member 63 is hollow and internally comprises a first transmission portion 631 and a second transmission portion 632. The first transmission portion 631 is located at the lower edge of the first transmission member 63, while the second transmission portion 632 is located at the upper edge of the first transmission member 63. The first actuator 62 is located within the first transmission member 63, with the first and second transmission portions 631 and 632 located on either side of the first actuator 62. When the first motor 61 drives the first actuator 62 to rotate, the first actuator 62 abuts against the first and second transmission portions 631 and 632, thereby enabling the entire first transmission member 63 to reciprocate. The first gear 64 is fixed relative to the second solar panel 40 and engages the first transmission member 63. Displacement of the first transmission member 63 drives the first gear 64 to rotate forward or reverse, thereby engaging or disengaging the second solar panel 40 relative to the first solar panel 30.

[0071] When the first motor 61 rotates, the first shifting member 62 will first shift the first transmission part 631, thereby moving the first transmission member 63, and the first transmission member 63 drives the first gear 64 to rotate, and further the second solar panel 40 is engaged with the first solar panel 30; when the first motor 61 continues to rotate, the first shifting member 62 will continue to rotate and shift the second transmission part 632, so that the first transmission member 63 moves in the opposite direction, and the first transmission member 63 drives the first gear 64 to rotate, and further the second solar panel 40 is opened relative to the first solar panel 30.

[0072] See Figure 16The hydraulic assembly 90 includes a first hydraulic assembly 901, which includes a first hydraulic cylinder 9011, a first piston member 9012, a first rack 9013, and a buffer cylinder 9014. The first piston member 9012 includes two first piston portions 9015 and a first elastic member 9016. The two ends of the first elastic member 9016 are respectively connected to the two first piston portions 9015, and the two first piston portions 9015 and the first elastic member 9016 are both disposed within the first hydraulic cylinder 9011. The first rack 9013 meshes with the first gear 64 and is connected to the first piston portion 9015. The first hydraulic cylinder 9011 is connected to the buffer cylinder 9014, and a transmission rod 9017 within the buffer cylinder 9014 is connected to the cleaning assembly 80. When the first gear 64 rotates forward or reverse, the first gear 64 can drive the first rack 9013 to rise or fall, thereby causing the first rack 9013 to drive the first piston 9012 to move. The first piston 9012 compresses or expands the space in the first hydraulic cylinder 9011, thereby adjusting the flow of liquid between the first hydraulic cylinder 9011 and the buffer cylinder 9014. The liquid flows into the first hydraulic cylinder 9011 or the buffer cylinder 9014, thereby causing the transmission rod 9017 to drive the cleaning assembly 80 to achieve reciprocating translation. It should be noted that due to the presence of the first elastic member 9016, when the first rack 9013 drives the first piston portion 9015 to move, the first elastic member 9016 can buffer the force applied by the first piston portion 9015 to the other first piston portion 9015, thereby buffering the flow of liquid in the first hydraulic cylinder 9011 and the buffer cylinder 9014.

[0073] The cleaning assembly 80 includes a supporting portion 81, a second gear 82, and a cleaning roller 83. The supporting portion 81 is connected to the transmission rod 9017. The cleaning roller 83 passes through the first guide plate 11 and the second guide plate 12 and can slide relative to the first guide plate 11 and the second guide plate 12. The second gear 82 is fixedly connected to the cleaning roller 83 and is rotatably mounted on the supporting portion 81. The second base 20 is provided with a guide portion 21, which extends along the length of the first solar panel 30. The second gear 82 engages the guide portion 21. Therefore, when the transmission rod 9017 drives the supporting portion 81 to move, the supporting portion 81 can also drive the second gear 82 to move. Due to the meshing relationship, the second gear 82 rotates and drives the cleaning roller 83 to rotate together, so that the cleaning roller 83 cleans the first solar panel 30, the second solar panel 40, and the third solar panel 50.

[0074] The first base 10 includes a first guide plate 11 and a second guide plate 12 arranged opposite to each other. The first guide plate 11 is provided with a first extension groove 111 and a second extension groove 112. The second guide plate 12 is provided with a third extension groove 121 and a fourth extension groove 122. The first extension groove 111 and the third extension groove 121 are located at the same horizontal height, and the second extension groove 112 and the fourth extension groove 122 are located at the same horizontal height. The cleaning roller 83 includes a first cleaning roller 831 and a second cleaning roller 832. The first cleaning roller 831 is penetrated by the first extension groove 111 and the third extension groove 121, and the second cleaning roller 832 is penetrated by the second extension groove 112 and the fourth extension groove 122. The first cleaning roller 831 is fixedly connected to the second gear 82, and the second cleaning roller 832 is fixedly connected to the fourth gear 84, and the second gear 82 engages with the fourth gear 84, so that when the second gear 82 rotates, it can not only drive the first cleaning roller 831 to rotate, but also drive the second cleaning roller 832 to rotate through the fourth gear 84, thereby realizing the rotational cleaning of the first cleaning roller 831 and the second cleaning roller 832, which is beneficial to all-round cleaning.

[0075] The cleaning assembly 80 also includes a connecting member 85, which is located on one side of the second guide plate 12 and connects the ends of the first cleaning roller 831 and the second cleaning roller 832 extending out of the second guide plate 12, so that the first cleaning roller 831 and the second cleaning roller 832 can synchronously clean the same vertical position, which is conducive to all-round cleaning without dead angles.

[0076] The foldable photovoltaic assembly 100 also includes a swing rod 13, which is rotatably arranged on the first guide plate 11 and is located on the same side as the second gear 82. The rod body of the swing rod 13 is rotatably arranged on the first guide plate 11 as the rotation center. The distance between one end of the swing rod 13 close to the first gear 64 and the rotation center is greater than the distance between the other end and the rotation center, so that the center of gravity of the swing rod 13 is biased toward the second gear 82. One end of the swing rod 13 is against the second gear 82, and the other end extends above the first guide plate 11. When the second solar panel 40 rotates and engages with the first solar panel 30 driven by the first driving assembly 60, the second solar panel 40 will press against the portion of the swing rod 13 extending above the first guide plate 11, so that the swing rod 13 rotates, and the swing rod 13 cannot directly or indirectly press against the second gear 82, and then the swing rod 13 avoids the cleaning assembly 80, so that the second gear 82 can move horizontally, and then the cleaning assembly 80 can clean. This makes it possible for the cleaning assembly 80 to move when the first driving assembly 60 drives the second solar panel 40 to engage with the first solar panel 30, which is beneficial to improving the cleaning level of the second solar panel 40 and further beneficial to photovoltaic power generation.

[0077] The second drive assembly 70 includes a second motor 71, a second actuator 72, a second transmission member 73, and a third gear 74. The second motor 71 is fixedly mounted on the second base 20, and the second actuator 72 is fixedly mounted on the output end of the second motor 71. Rotation of the output end of the second motor 71 drives the second actuator 72 to rotate with it. The second transmission member 73 is slidably mounted on the second base 20. The second transmission member 73 is hollow and internally defines a third transmission portion 731 and a fourth transmission portion 732. The third transmission portion 731 is located at the lower edge of the second transmission member 73, and the fourth transmission portion 732 is located at the upper edge of the second transmission member 73. The second actuator 72 is located within the second transmission member 73, with the third transmission portion 731 and the fourth transmission portion 732 located on either side of the second actuator 72. When the second motor 71 drives the second actuator 72 to rotate, the second actuator 72 abuts against the third transmission portion 731 and the fourth transmission portion 732, thereby enabling the second actuator 73 to move back and forth. The third gear 74 is fixed relative to the third solar panel 50 and engages with the second transmission member 73. When the second transmission member 73 is displaced, it can drive the third gear 74 to rotate forward or reverse, thereby engaging or unlocking the third solar panel 50 relative to the first solar panel 30.

[0078] When the second motor 71 rotates, the second toggle member 72 first toggle the third transmission part 731, thereby moving the second transmission member 73, and the second transmission member 73 drives the third gear 74 to rotate, further causing the third solar panel 50 to engage with the first solar panel 30; when the third motor continues to rotate, the second toggle member 72 continues to rotate and toggle the fourth transmission part 732, thereby moving the second transmission member 73 in the opposite direction, and the second transmission member 73 drives the third gear 74 to rotate, further causing the third solar panel 50 to open relative to the first solar panel 30.

[0079] The hydraulic assembly 90 includes a second hydraulic assembly 902, which includes a second hydraulic cylinder 9021, a second piston 9022, and a first rack 9013. The second piston 9022 includes two second piston portions 9024 and a second elastic member 9025. The ends of the second elastic member 9025 are connected to the two second piston portions 9024, respectively. Both the second piston portions 9024 and the second elastic member 9025 are disposed within the second hydraulic cylinder 9021. The second rack 9023 meshes with the third gear 74 and is connected to the second piston portion 9024. The second hydraulic cylinder 9021 is also connected to the buffer cylinder 9014. The transmission rod 9017 within the buffer cylinder 9014 is connected to the cleaning assembly 80. When the second gear 82 rotates forward or reverse, the third gear 74 can drive the second rack 9023 to rise or fall, thereby causing the second rack 9023 to drive the second piston 9022 to move. The second piston 9022 compresses or expands the space in the second hydraulic cylinder 9021, thereby adjusting the flow of liquid between the second hydraulic cylinder 9021 and the buffer cylinder 9014. The liquid flows into the second hydraulic cylinder 9021 or the buffer cylinder 9014, thereby causing the transmission rod 9017 to drive the cleaning assembly 80 to achieve reciprocating translation. It should be noted that due to the presence of the second elastic member 9025, when the second rack 9023 drives the second piston portion 9024 to move, the second elastic member 9025 can buffer the force applied by the second piston portion 9024 to the other second piston portion 9024, thereby buffering the flow of liquid in the second hydraulic cylinder 9021 and the buffer cylinder 9014.

[0080] See Figure 13 and Figure 15 A locking piece 14 is rotatably provided on the second guide plate 12. The locking piece 14 is located at the junction of the second solar panel 40 and the third solar panel 50 where the first solar panel 30 is buckled. A stop portion 124 is provided on the second guide plate 12; when the cleaning assembly 80 moves to the junction of the second solar panel 40 and the third solar panel 50, the cleaning assembly 80 will press the locking piece 14 against the stop portion 124, so that the locking piece 14 cannot rotate. On the contrary, the locking piece 14 can press against the connecting piece 85 in the cleaning assembly 80 to limit the movement of the cleaning assembly 80. When the third solar panel 50 is buckled with the first solar panel 30, the third solar panel 50 can press against the locking piece 14, causing the locking piece 14 to rotate in a direction away from the stop portion 124, thereby avoiding the cleaning assembly 80 and allowing the cleaning assembly 80 to continue moving.

[0081] In this embodiment, the locking member 14 is further provided with a torsion spring (not shown), which can reset the locking member 14 to ensure normal transmission next time. It is understandable that in other embodiments, the locking member 14 can be reset by other means.

[0082] In this embodiment, driven by the first drive assembly 60, when the first hydraulic cylinder 9011 is in the extreme state of compression, the liquid in the first hydraulic cylinder 9011 flows to the cache cylinder 9014 to the maximum extent, and the liquid flowing into the cache cylinder 9014 at this time causes the transmission rod 9017 to drive the cleaning assembly 80 to move as far as the junction of the second solar panel 40 and the third solar panel 50, and with the drive of the second drive assembly 70, the liquid in the second hydraulic cylinder 9021 further flows to the cache cylinder 9014, thereby further transmitting the rod 9017 to drive the cleaning assembly 80 to continue moving; it can be understood that in other embodiments, other settings can also be presented.

[0083] The cleaning process of the foldable photovoltaic module 100 provided by the present invention is as follows:

[0084] The first motor 61 in the first driving assembly 60 drives the first toggle member 62 to rotate, the first toggle member 62 abuts the first transmission part 631, the first transmission member 63 moves horizontally, and then the first transmission member 63 drives the first gear 64 to rotate. Since the first gear 64 is fixedly connected to the second solar panel 40, the second solar panel 40 is closed relative to the first solar panel 30, and the second solar panel 40 abuts the swing rod 13 to rotate, so that the swing rod 13 no longer abuts the second gear 82 and allows the cleaning assembly 80 to move. In this process, the first gear 64 drives the first rack 9013 to move, and the first rack 9013 drives the first piston part 9015 to move in the first hydraulic cylinder 9011. Due to the first elastic member 90 16, when the second solar panel 40 is buckled with the first solar panel 30, the first elastic member 9016 will perform buffering, and the liquid in the first hydraulic cylinder 9011 will not be compressed immediately. After the buffering, the space for storing liquid in the first hydraulic cylinder 9011 is compressed, and the liquid flows to the cache cylinder 9014, and further the liquid pushes the transmission rod 9017 in the cache cylinder 9014 to move, and the transmission rod 9017 drives the supporting portion 81 to move, and the second gear 82 rotatably connected to the supporting portion 81 engages with the guide portion 21 to rotate relative to each other, and then the second gear 82 drives the first cleaning roller 831 to rotate, and at the same time the second gear 82 engages with the fourth gear 84 to rotate, and the fourth gear 84 drives the second cleaning roller 832 to rotate. , so that the first cleaning roller 831 and the second cleaning roller 832 clean at the same time, and the translation of the supporting portion 81 drives the first cleaning roller 831 to slide along the first extension groove 111 and the third extension groove 121, and the second cleaning roller 832 to slide along the second extension groove 112 and the fourth extension groove 122, and the liquid in the buffer cylinder 9014 flowing into the first hydraulic cylinder 9011 can push the cleaning assembly 80 to the hinge where the second solar panel 40 and the third solar panel 50 are closed, and the connecting member 85 abuts the locking member 14 to limit the displacement of the cleaning assembly 80. At this time, the second motor 71 in the second driving assembly 70 drives the second toggle member 72 to move, and then the second transmission member 73 moves, similarly to the first driving assembly During the transmission process of the component 60 and the first hydraulic component 901, the third roller drives the third solar panel 50 to rotate. When the third solar panel 50 is engaged with the first solar panel 30, the third solar panel 50 rotates against the locking component 14, and the third roller drives the second rack 9023 to move. The second piston portion 9024 compresses the space in the second hydraulic cylinder 9021. Similarly, the second elastic component 9025 can play a buffering role. After the liquid in the second hydraulic cylinder 9021 flows to the cache cylinder 9014, the transmission rod 9017 continues to drive the cleaning component 80 to move, further cleaning the other part of the first solar panel 30 and the third solar panel 50 until the cleaning is completed, which is beneficial to the subsequent photovoltaic power generation of the foldable photovoltaic component 100.

[0085] After cleaning is completed, the second motor 71 continues to rotate, so that the second transmission member 73 translates in the opposite direction, thereby driving the third gear 74 to rotate in the opposite direction, and the second rack 9023 drives the second piston member 9022 to move, and the space in the second hydraulic cylinder 9021 expands, and part of the liquid in the buffer cylinder 9014 flows to the second hydraulic cylinder 9021, and then under the action of pressure, the transmission rod 9017 drives the cleaning component 80 to move in the opposite direction, and the cleaning component 80 presses the locking member 14 away from the stop portion 124 to rotate and move to the second solar panel 40 and the third solar panel. At the junction of the plates 50, the first motor 61 continues to rotate, the first gear 64 rotates in the opposite direction, the first rack 9013 drives the first piston 9012 to move, and the space in the first hydraulic cylinder 9011 expands, and the remaining liquid in the cache cylinder 9014 flows to the first hydraulic cylinder 9011. Under the action of pressure, the transmission rod 9017 further drives the cleaning component 80 to move, and the second gear 82 in the cleaning component 80 passes over the swing rod 13. The cleaning component 80 moves to the end, and the swing rod 13 resists the second gear 82, and is reset after complete cleaning.
