Description

Technical Field

[0001] This utility model relates to the field of solar panel technology, and in particular to a foldable solar panel that is easy to unfold and store. Background Technology

[0002] A solar panel is a device that converts solar energy into electrical energy. It is also known as a "solar panel" or "photovoltaic panel". Foldable solar panels are a type of solar panel. Foldable solar panels take up little space when folded, making them easy to store and transport. When unfolded, they have a large area for receiving sunlight and have good power generation efficiency.

[0003] Existing patent CN204886834U discloses a foldable solar panel, comprising: a first frame, a second frame, a solar cell body, an EVA filling layer, and an angle adjuster. The first frame and the second frame are connected by an axis. An angle adjuster is provided at the bottom of the first frame and the top of the second frame, and the angle adjuster is driven by a hydraulic pump. The included angle between the first frame and the second frame ranges from 30 to 160 degrees. The solar cell body is located between the first frame and the second frame. The outer surface of the solar cell body is provided with an EVA filling layer. A back plate is provided on the back of the first frame and the second frame. Through the above method, this foldable solar panel has a simple structure, consisting of two solar cells, and has a folding function. When not in use, it can be folded up to protect the surface of the solar cells, extend its service life, and has high stability.

[0004] The aforementioned foldable solar panel requires an angle adjuster to unfold and be fixed at a set angle for limitation when unfolded. This structure is complex and the unfolding and folding operations are inconvenient. Utility Model Content

[0005] To address the problems in related technologies, this application discloses a foldable solar panel that is easy to unfold and store, solving the problem of inconvenient unfolding and storage of foldable solar panels in related technologies.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A foldable solar panel that is easy to unfold and store includes multiple solar panels, each comprising an active panel and a passive panel. The active and passive panels are alternately connected and a limiting hinge device is provided between them. When the solar panel is folded up, the top of the active panel is hinged to the top of the passive panel, and the bottom of the active panel is hinged to the bottom of the passive panel. When the solar panel is unfolded, the top of the active panel is fixed to the top of the passive panel, and the bottom of the active panel is fixed to the bottom of the passive panel. After the solar panel is unfolded, the active and passive panels are fixed at an unfolding angle. A rotating wheel is provided at the bottom of the active panel, which rotates when the solar panel is unfolded.

[0008] As a further aspect of this application: the unfolding angle is the angle between the active plate or the driven plate and the horizontal plane, and the unfolding angle is 5-15 degrees.

[0009] As a further aspect of this application: the limiting hinge device includes a hinge shaft and a matching hinge block. One end of the hinge block is fixedly connected to the solar panel, and the other end of the hinge block is provided with a plurality of alternately arranged hinge rods. The hinge rods are provided with hinge holes, and the hinge holes are matched with the hinge shaft. The hinge rods are alternately engaged and connected to the hinge shaft. The hinge block is triangular in shape, and when the solar panel is unfolded, the corresponding hinge block abuts against and is fixed.

[0010] As a further aspect of this application: the rotating wheels are disposed on both sides of the bottom end of the active plate.

[0011] As a further aspect of this application: the rotating wheel is a drive wheel, which provides power for the unfolding and retraction of the solar panel.

[0012] As a further aspect of this application: a connecting rod is fixedly provided at the bottom end of the active plate, and the other end of the connecting rod is connected to the rotating wheel.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] 1. A foldable solar panel that is easy to unfold and store. The active and passive solar panels are connected alternately, with a limiting hinge device between them. When the solar panel is folded, adjacent solar panels are folded together. When the solar panel is unfolded, adjacent solar panels are fixed at a certain unfolding angle. The bottom of the active panel has a rotating wheel. The rotating wheel rotates when the solar panel is unfolded. Under the action of force, the rotating wheel rotates, and the active and passive panels move to unfold and store. Adjacent solar panels are fixed at a certain unfolding angle, which is the angle between the active or passive panel and the horizontal plane. The unfolding angle is 5-15 degrees, which improves the smoothness of the solar panel when folding and the stability of the solar panel after unfolding. The rotating wheel improves the smoothness of the solar panel movement.

[0015] 2. The limiting hinge device includes a hinge shaft and matching hinge blocks. The matching hinge blocks are connected to the hinge shaft rotation shaft by multiple alternately interlocking hinge rods. The hinge blocks are triangular blocks. When the solar panel is unfolded, the corresponding hinge blocks abut against and are fixed in place. This limiting hinge device has a simple structure and strong limiting stability.

[0016] 3. The rotating wheel is the driving wheel, which provides power for the unfolding and retraction of the solar panel, improving the automation of the unfolding and retraction of the solar panel and improving the stability of the solar panel movement.

[0017] 4. A connecting rod is fixedly installed at the bottom of the active panel, and the other end of the connecting rod is connected to a rotating wheel. The connecting rod increases the height of the solar panel chassis and improves the mobility of the solar panel. Attached Figure Description

[0027] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] like Figure 1-2 As shown:

[0029] A foldable solar panel that is easy to unfold and store includes multiple solar panels, each including an active panel 1 and a passive panel 2, which are connected alternately to each other.

[0030] The active plate 1 and the driven plate 2 are hinged and limited by a limiting hinge device 3. When the solar panels are stored and closed, the top of the active plate 1 is hinged and closed with the top of the driven plate 2, and the bottom of the active plate 1 is hinged and closed with the bottom of the driven plate 2.

[0031] When the solar panel is unfolded, the top of the active panel 1 is fixed to the top of the driven panel 2, and the bottom of the active panel 1 is fixed to the bottom of the driven panel 2.

[0032] After the solar panel is unfolded, the active panel 1 and the driven panel 2 are fixed by an unfolding angle. The unfolding angle is the angle between the active panel 1 or the driven panel 2 and the horizontal plane, and the unfolding angle is 5-15 degrees. The unfolding angle is preferably 10 degrees.

[0033] The bottom of the active plate 1 is equipped with a rotating wheel 4. The rotating wheel 4 rotates to retract and unfold the solar panel. Preferably, the rotating wheel 4 is an active wheel. The rotating wheel 4 provides power for the unfolding and retraction of the solar panel, thereby improving the automation level of the unfolding and retraction of the solar panel.

[0034] Rotating wheels 4 are located on both sides of the bottom end of the active plate 1. A connecting rod 5 is fixedly provided at the bottom end of the active plate 1, and the other end of the connecting rod 5 is connected to the rotating wheel 4.

[0035] Preferably, the limiting hinge device 3 includes a hinge shaft 31 and a matching hinge block 32. One end of the hinge block 32 is fixedly connected to the solar panel, and the other end of the hinge block 32 is provided with a plurality of alternately arranged hinge rods 33. The hinge rods 33 are provided with hinge holes 34, and the hinge holes 34 are matched with the hinge shaft 31. The hinge rods 33 are alternately engaged and connected to the hinge shaft 31. The hinge block 32 is triangular. Different shapes of triangular block hinge blocks 32 can achieve limiting and fixing of different unfolding angles. When the solar panel is unfolded, the corresponding hinge block 32 abuts and is fixed.

[0036] In practical applications:

[0037] The active solar panel 1 and the driven solar panel 2 are connected alternately. A limiting hinge device 3 is provided between the active panel 1 and the driven solar panel 2. Through the limiting hinge device 3, the adjacent solar panels are stored side by side when the solar panels are stored. When the solar panels are unfolded, the adjacent solar panels are limited and fixed at a certain unfolding angle. The bottom of the active panel 1 is provided with a rotating wheel 4. The rotating wheel 4 rotates when the solar panels are stored and unfolded. Under the action of force, the rotating wheel 4 rotates, and the active panel 1 and the driven solar panel 2 move to unfold and store. The adjacent solar panels are limited and fixed at a certain unfolding angle. The unfolding angle is the angle between the active panel 1 or the driven solar panel 2 and the horizontal plane. The unfolding angle is 10 degrees, which improves the smoothness of the solar panels when stored and the stability of the solar panels after unfolding. The rotating wheel 4 improves the smoothness of the movement of the solar panels.

[0038] The limiting hinge device 3 includes a hinge shaft 31 and a matching hinge block 32. The matching hinge block 32 is connected to the hinge shaft 31 through multiple alternately arranged hinge rods 33. The hinge block 32 is triangular in shape. When the solar panel is unfolded, the corresponding hinge block 32 abuts and is fixed. This limiting hinge device 3 has a simple structure and strong limiting stability.

[0039] Rotating wheel 4 is the driving wheel, which provides power for the unfolding and retraction of the solar panel, improving the automation of the unfolding and retraction of the solar panel and improving the stability of the solar panel movement.

[0040] A connecting rod 5 is fixedly installed at the bottom of the active panel 1. The other end of the connecting rod 5 is connected to a rotating wheel 4. The connecting rod 5 increases the height of the solar panel chassis and improves the mobility of the solar panel.
