Technical Field

[0001] This application relates to the field of photovoltaic product technology, and in particular to a hinge, a solar module, and a solar device. Background Technology

[0002] Foldable solar panels typically consist of multiple solar panels connected by rotating joints. During transport, the foldable solar panel can be switched to a folded state, making it compact and easy to move. During deployment, the solar panels can be unfolded, providing high power generation and ease of deployment. However, due to the limitations of the rotating joint structure, adjacent solar panels are prone to interference and collisions when folded, leading to potential damage. Furthermore, the compactness of the folded state needs improvement. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, this application provides a hinge, a solar panel, and a solar device, which makes it less likely for two objects connected by the hinge to interfere with each other in the folded state, and also has a high degree of compactness.

[0004] To solve the above problems, the technical solution provided in this application is:

[0005] A hinge includes a hinge axis and two hinge members hinged to each other via the hinge axis, the hinge members including a first hinge portion and a second hinge portion;

[0006] One end of the first hinge portion is connected to the hinge shaft.

[0007] One end of the second hinge is connected to the other end of the first hinge, and the second hinge is bent relative to the first hinge in the folding direction of the hinge. The second hinge is used to connect with an external object.

[0008] In some embodiments, at least one of the hinge members is provided with a first stop portion, the first stop portion being configured to stop each other with another first stop portion or another hinge member when the two hinge members are extended to a first target angle, so as to limit the two hinge members from continuing to extend.

[0009] In some embodiments, one end of the second hinge portion that is connected to the first hinge portion protrudes from the first hinge portion to form the first stop portion.

[0010] In some embodiments, the first hinge portion has a boss on the side facing the unfolding direction of the hinge member, and the first stop portion is formed by the boss.

[0011] In some embodiments, at least one of the hinge members is provided with a second stop portion, the second stop portion being configured to stop each other with another second stop portion or another hinge member when the two hinge members are folded to a second target angle, so as to limit the two hinge members from continuing to fold.

[0012] In some embodiments, the hinge further includes an elastic element connected between the two hinge members, the elastic element being configured to apply a spring force to the hinge members during the unfolding or folding process of the two hinge members, thereby slowing down the unfolding or folding speed of the hinge members.

[0013] In some embodiments, the hinge further includes a base, and the other end of the second hinge is connected to the base, the base being used for connection to an external object.

[0014] A solar panel module includes a plurality of solar panel units arranged in sequence and at least one hinge as described above, wherein adjacent solar panel units are interconnected by the hinge.

[0015] In some embodiments, the solar panel unit includes a frame and a solar panel disposed on the frame, the frame including a frame and a plurality of reinforcing ribs connected to the frame.

[0016] In some embodiments, the reinforcing rib and / or the frame are provided with a wire-passing channel, and the wire-passing channel extends to the outer peripheral surface of the frame to form a wire-passing opening, and the wire-passing openings on adjacent solar panel units are arranged opposite to each other.

[0017] In some embodiments, the at least one hinge includes a first hinge and a second hinge, with the top edges of two adjacent solar panel units connected to each other via the first hinge and the bottom edges of two adjacent solar panel units connected to each other via the second hinge.

[0018] In some embodiments, the second hinge further includes a first roller rotatably connected to the hinge axis of the second hinge.

[0019] In some embodiments, two adjacent second hinges in the extension direction of the solar module are arranged offset in the axial direction of the hinge shaft.

[0020] In some embodiments, the solar panel unit is provided with a flexible buffer block, which can abut against the flexible buffer block of one solar panel unit or the flexible buffer block of another solar panel unit when two adjacent solar panel units are folded to a second target angle.

[0021] In some embodiments, the solar module further includes a protective plate connected via the hinge to the first and / or last of a plurality of sequentially arranged solar panel units.

[0022] In some embodiments, the protective plate has a support leg on the side facing away from the solar panel unit, one end of the support leg is rotatably connected to the protective plate, and the other end of the support leg is provided with a second roller.

[0023] In some embodiments, the side of the protective plate facing away from the solar panel unit is provided with a cable winder for winding cables.

[0024] A solar energy device comprising at least one solar energy component as described above.

[0025] In this application's hinge, the second hinge portion bends relative to the extension line of the first hinge portion in the folding direction of the hinge. When the two second hinge portions rotate to a parallel or nearly parallel state, the two first hinge portions gradually move away from each other and form a gap as they extend from the hinge axis to the second hinge portions, providing clearance space for the two second hinge portions. This also provides clearance space for two external objects connected to the second hinge portions, allowing the two external objects to rotate to a parallel or nearly parallel state. This not only improves the compactness of the two external objects in the folded state but also avoids interference and collisions between the external objects. Attached Figure Description

[0046] To enable those skilled in the art to better understand the technical solutions of the embodiments of this application, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] See Figures 1 to 4 As shown, this application embodiment provides a hinge 100, which includes a hinge shaft 110 and two hinge members 120 hinged to each other via the hinge shaft 110. Each hinge member 120 includes a first hinge portion 122 and a second hinge portion 123. One end of the first hinge portion 122 is connected to the hinge shaft 110, and one end of the second hinge portion 123 is connected to the other end of the first hinge portion 122. The second hinge portion 123 bends relative to the first hinge portion 122 in the folding direction of the hinge member 120, and is used to connect with an external object. Optionally, the first hinge portion 122 and the second hinge portion 123 can be an integral structure or formed by a separate structure fixedly connected to each other. The second hinge portion 123 is used to connect with an external object, including both direct and indirect connections.

[0048] The folding direction is the direction of movement of the hinge member 120 during the folding process of the hinge 100. Corresponding to the folding direction, the hinge 100 also has an unfolding direction, which is the direction of movement of the hinge member 120 during the unfolding process of the hinge 100. Figure 1 Taking the hinge shown as an example, Figure 1 The hinge on the left side of the middle part folds counterclockwise and unfolds clockwise, respectively. Figure 1 The hinge on the right side of the middle part folds clockwise and unfolds counterclockwise, respectively.

[0049] In fact, one end of the two hinge members 120 can be hinged to each other via the hinge shaft 110. A portion of the hinge member 120 near the hinge shaft 110 forms the first hinge portion 122, and a portion of the hinge member 120 away from the hinge shaft 110 is bent relative to the first hinge portion 122 in the folding direction of the hinge member 120 to form the second hinge portion 123.

[0050] When the two second hinge parts 123 rotate to a parallel or nearly parallel state, the two first hinge parts 122 gradually move away from each other as they extend from the hinge axis 110 toward the second hinge parts 123, forming a gap that gradually increases until they connect with the second hinge parts 123. Figure 1 and Figure 2 As shown, clearance space is provided for the two second hinge portions 123, and clearance space is also provided for the two external objects connected to the second hinge portions 123, so that the two external objects can rotate to a state that is parallel or nearly parallel to each other. This not only improves the compactness of the two external objects in the folded state, but also avoids interference and collision between the external objects.

[0051] For example, taking two solar panel units 210 connected to each other via the hinge 100 as an example, the two solar panel units 210 can be folded into a parallel or nearly parallel state, which can improve the compactness of the two solar panel units 210 in the folded state and reduce the spatial size of the two solar panel units 210 in the folded state. In addition, since the solar panel units 210 are less likely to interfere with or collide with each other, damage to the solar panel units 210 due to mutual interference or collision can also be avoided.

[0052] It should be noted that the external object may include various objects that need to be rotatably connected to another object via the hinge 100, and is not limited to the solar panel unit 210. The types of objects that are connected to each other via the hinge 100 are not limited here.

[0053] In practical applications, the bending angle of the second hinge portion 123 relative to the first hinge portion 122 can be set according to actual needs. For example, the second hinge portion 123 can be bent at a relatively large angle relative to the first hinge portion 122, so that the first hinge portion 122 and the second hinge portion 123 are nearly perpendicular to each other. Figures 1 to 4 As shown in the first embodiment. For example, the second hinge portion 123 can be bent at a relatively small angle relative to the first hinge portion 122, such that the first hinge portion 122 and the second hinge portion 123 form an obtuse angle, such as... Figures 5 to 7 The second embodiment, and Figures 8 to 10 The third embodiment is shown in the figure.

[0054] Cooperate Figures 1 to 4 As shown, in some embodiments, at least one of the hinge members 120 is provided with a first stop 124. The first stop 124 is configured to stop each other with another first stop 124 or another hinge member 120 when the two hinge members 120 are extended to a first target angle, thereby limiting the further extension of the two hinge members 120. Figure 3 and Figure 4 As shown. In this way, the two external objects can be prevented from over-expanding, and their current orientation can be maintained.

[0055] Optionally, the first stop 124 may be provided on one of the hinge members 120. The first stop 124 may be configured to stop the other hinge member 120 when the two hinge members 120 are extended to the first target angle, thereby restricting the two hinge members 120 from continuing to extend.

[0056] Optionally, a first stop 124 may be provided on each of the two hinge members 120. The two first stopes 124 may be configured to stop each other when the two hinge members 120 are extended to a first target angle, so as to limit the two hinge members 120 from continuing to extend.

[0057] Optionally, the first stop portion 124 may be configured to stop each other with another first stop portion 124 or another hinge member 120 when the two first hinge portions 122 are extended to the first target angle, or it may stop each other with another first stop portion 124 or another hinge member 120 when the two second hinge portions 123 are extended to the first target angle.

[0058] Optionally, the first target angle can be any angle between 0° and 360°. For example, the first target angle can be any angle between 0° and 180°, using the inner or outer contour line of the second hinge portion 123 as a reference.

[0059] In some embodiments, one end of the second hinge portion 123 connected to the first hinge portion 122 protrudes beyond the first hinge portion 122 to form the first stop portion 124. For example, one end of the second hinge portion 123 may protrude beyond the first hinge portion 122 to form a first stop portion 124 with a trapezoidal longitudinal section, such as... Figures 1 to 4 As shown. When the two hinge members 120 are extended to the first target angle, the two trapezoidal waists on the longitudinal section abut against each other, restricting the two hinge members 120 from extending further, as shown. Figure 3 and Figure 4 As shown. Of course, the longitudinal section of the first stop portion 124 can be constructed in any shape, such as hemispherical, semi-cylindrical, etc., and is not limited to being trapezoidal.

[0060] In some embodiments, the first hinge portion 122 has a boss on one side facing the unfolding direction of the hinge member 120, and the boss forms the first stop portion 124. The unfolding direction is the direction of movement of the hinge member 120 during the transition of the hinge 100 from a folded state to an unfolded state. Optionally, the boss may be located on the first hinge portion 122 near the hinge axis 110, or it may be located on the first hinge portion 122 near the second hinge portion 123.

[0061] It should be noted that, in specific implementations, the first stop 124 can be implemented in various ways and should not be construed as being limited to the above-described embodiments. For example, a stop arm capable of interfering with another hinge 120 can be provided on one hinge 120, etc.

[0062] In some embodiments, at least one of the hinge members 120 is provided with a second stop (not shown in the figure). The second stop is configured to stop each other with another second stop or another hinge member 120 when the two hinge members 120 are folded to a second target angle, thereby limiting the further folding of the two hinge members 120. In this way, interference between the two hinge members 120 can be avoided, and collision between the two external objects connected by the hinge 100 can also be avoided.

[0063] Optionally, with reference to the second hinge portion 123, the second target angle can be 0° or close to 0°. In this way, when the two second hinge portions 123 rotate to be parallel or nearly parallel to each other, the second stop restricts the two hinge members 120 from continuing to fold, thereby preventing collision between the two external objects. With reference to the first hinge portion 122, the second target angle can be the angle formed by the two first hinge portions 122 when the two second hinge portions 123 are parallel or nearly parallel to each other.

[0064] Optionally, the second stop may be disposed on the first hinge portion 122 or on the second hinge portion 123. The second stop may be formed by a stop block or a stop arm. For example, a flexible stop block may be disposed on the side of one of the second hinge portions 123 facing the folding direction. This flexible stop block may be configured to stop the other second hinge portion 123 when the two second hinge portions 123 are folded to be parallel or nearly parallel to each other, thereby limiting the further folding of the two hinge members 120.

[0065] Cooperate Figure 2As shown, in some embodiments, the hinge 100 further includes an elastic element 130 connected between the two hinge members 120. The elastic element 130 is configured to apply a spring force to the hinge members 120 during the unfolding or folding process, thereby slowing down the unfolding or folding speed of the hinge members 120. This improves the stability of the hinge 100 during unfolding or folding, prevents collisions between external objects connected by the hinge 100, and provides cushioning for the hinge 100 itself, preventing damage from excessive instantaneous impact due to excessive speed.

[0066] Optionally, the elastic element 130 can be configured to apply elastic forces toward the unfolding direction to the two hinge members 120 respectively. In this way, the folding speed of the hinge members 120 can be slowed down during the folding process of the hinge 100, avoiding collisions between the two hinge members 120 or two external objects connected by the hinge 100; during the unfolding process, it can assist the hinge 100 in unfolding, making it easier for the user to unfold external objects connected by the hinge 100.

[0067] Optionally, the elastic element 130 may include a torsion spring, which may be sleeved on the hinge shaft 110 of the hinge 100. The two ends of the torsion spring may respectively abut against the two first hinge portions 122, and the torsion spring may be configured to be in a compressed state. In this way, the torsion spring can apply a spring force in the unfolding direction to the two hinge members 120 respectively.

[0068] It should be noted that the elastic element 130 is not limited to a torsion spring, but may also be other elastic elements 130. The elastic element 130 is not limited to being connected to the hinge shaft 110, but may also be disposed, for example, between two first hinge parts 122 or between two second hinge parts 123.

[0069] In specific implementations, the shape and structure of the hinge 120 can be implemented in various ways. The following examples illustrate the specific shape and structure of the hinge 120 with reference to several specific embodiments, but it should not be construed as the hinge 120 being limited to the following structures.

[0070] Cooperate Figures 1 to 4 As shown, in some embodiments, the first hinge portion 122 may include two opposing plate-like structures, which may be disposed at one end of the second hinge portion 123. The first hinge portion 122 and the second hinge portion 123 may be perpendicular to each other or approximately perpendicular to each other. The cross-section of the second hinge portion 123 may be L-shaped or U-shaped, such that the second hinge portion 123 may cover the outside of the rectangular profile.

[0071] Cooperate Figures 5 to 7As shown, in some embodiments, the hinge 120 may further include a base 126, with the other end of the second hinge portion 123 connected to the base 126, which is used for connection to an external object. This facilitates the connection of the hinge 120 to an external object.

[0072] Optionally, the hinge may include a plurality of hinge arms 121 arranged side by side, wherein each hinge arm 121 includes a first hinge portion 122 and a second hinge portion 123.

[0073] Optionally, the hinge 120 may include a base 126 and two hinge arms 121. The two hinge arms 121 may be plate-shaped with their surfaces facing each other. One end of each hinge arm 121 is connected to the base 126, and the other end of each hinge arm 121 is provided with a shaft hole. A hinge shaft 110 passes through the shaft hole to hinge the two hinges 120. A portion of the hinge arm 121 near the hinge shaft 110 may extend radially along the hinge shaft 110 to form a first hinge portion 122. A portion of the hinge arm 121 near the base 126 may be bent in a folding direction relative to the first hinge portion 122 to form a second hinge portion 123.

[0074] Optionally, the hinge 120 may further include one or more connecting portions connected between the two hinge arms 121 to improve the structural strength and robustness of the hinge 120.

[0075] Optionally, the longitudinal section of the base 126 may be U-shaped, and the base 126 as a whole may be U-shaped groove, such as... Figures 5 to 7 As shown in the second embodiment, or as... Figures 8 to 10 As shown in the third embodiment, the base 126 can be covered on the outside of the structure such as the profile or frame 211 so that the base 126 can be connected to an external object.

[0076] Optionally, the longitudinal section of the base 126 may be L-shaped, such as... Figure 11 and Figure 12 As shown in the fourth embodiment, the base 126 can be punched on the outside of the profile or frame 211 and other structures to facilitate the connection of the base 126 with external objects.

[0077] Optionally, the base 126 is provided with a notch 127, and the other end of the second hinge portion 123 is provided with a plug portion 125. The plug portion 125 is inserted into the notch 127, and the other end of the second hinge portion 123 is welded to the base 126. Figures 8 to 10 As shown in the third embodiment. Alternatively, a notch 127 may be provided at the other end of the first hinge portion 122, and a plug portion 125 may be provided on the base 126, such as... Figure 11 and Figure 12 As shown in the fourth embodiment, this allows the base 126 and the hinge arm 121 to be securely welded together, thereby improving the robustness and structural strength of the hinge 100.

[0078] See Figures 13 to 16 As shown, this application provides a solar panel 200, which includes multiple solar panel units 210 and at least one hinge 100 as described in any of the above embodiments. The multiple solar panel units 210 are arranged sequentially, and adjacent solar panel units 210 are connected to each other by the hinge 100. In this way, adjacent solar panel units 210 can be folded to a parallel or nearly parallel state, and collisions or interference are less likely to occur. Figure 16 As shown, this is beneficial for reducing the size of the solar module 200 in its folded state, and for improving the convenience of transportation and storage, thereby reducing transportation and storage costs.

[0079] Optionally, the hinge 100 used in the solar module 200 can be as described in the first embodiment above, with an elastic element 130, such as a torsion spring, provided between the two hinge members 120 of the hinge 100. In this way, during the folding or unfolding of the solar module 200, the elastic element can provide a buffering force, preventing collisions between adjacent solar panel units 210 and avoiding excessive instantaneous impact force due to excessive movement speed. Furthermore, the elastic element 130 can also absorb external forces, preventing external forces from directly acting on the solar panel units 210, thus improving the movement stability of the solar module 100.

[0080] Cooperate Figure 17 and Figure 18 As shown, in some embodiments, the solar panel unit 210 may include a frame 211 and a solar panel 217 disposed on the frame 211, and the hinge 100 may be connected to the frame 211. This improves the structural strength of the solar panel unit 210 and provides an installation position for the hinge 100. Taking the hinge member 120 of the hinge 100 as an example, which includes a base 126 with a U-shaped or L-shaped longitudinal section, the U-shaped or L-shaped base 126 can be fastened to the frame 211 and connected to the frame 211 by connectors such as screws or rivets.

[0081] Optionally, the frame 211 may include a border 212, and the solar panel 217 may be connected to the area enclosed by the border 212. In this way, the border 212 can provide sufficient protection for the solar panel 217. For example, a raised ridge may be provided on the inner circumferential surface of the border 212, and the side edge of the solar panel 217 may overlap the raised ridge. The raised ridge may be formed by welding C-shaped or U-shaped steel to the inner circumferential surface of the border 212. Optionally, a handle may be provided on the side of the border 212 to facilitate the user to fold or unfold the solar module 200 by pulling the handle. Optionally, the border 212 may be rectangular, and the corresponding solar panel 217 may also be rectangular. Of course, the border 212 and the solar panel 217 may also be of other shapes.

[0082] Optionally, the frame 211 may further include a plurality of reinforcing ribs 213, the two ends of which can be connected to the side frame 212 respectively. The reinforcing ribs 213 not only further improve the structural strength of the frame 211, but also provide more adequate support and protection for the solar panel 217. The reinforcing ribs 213 can extend laterally or vertically. When the reinforcing ribs 213 extend laterally, a plurality of reinforcing ribs 213 can be arranged sequentially at intervals in the vertical direction; when the reinforcing ribs 213 extend vertically, a plurality of reinforcing ribs 213 can be arranged sequentially at intervals in the horizontal direction.

[0083] In some embodiments, the reinforcing rib 213 and / or the frame 212 are provided with a wire-passing channel 214, and the wire-passing channel 214 extends to the outer peripheral surface of the frame 212 to form a wire-passing opening 215, with the wire-passing openings 215 on adjacent solar panel units 210 being arranged opposite to each other. The wire-passing channel 214 and the wire-passing opening 215 are used to pass cables through. For example, the cable connecting the solar panel 217 can be placed in the wire-passing channel 214 and extend through the wire-passing opening 215 into the wire-passing channel 214 of another solar panel unit 210.

[0084] Optionally, the threading channel 214 can be disposed within the frame 212. For example, the frame 212 can be a hollow structure, with the threading channel 214 formed through the inner cavity of the frame 212. Optionally, the threading channel 214 can also be disposed on the reinforcing rib 213. For example, in conjunction with... Figure 19 As shown, the reinforcing rib 213 can extend vertically, and a wire-passing groove can be provided on the reinforcing rib 213. The wire-passing groove can extend along the length direction of the reinforcing rib 213 and pass through to both ends of the reinforcing rib 213. A through wire-passing hole can be provided on the frame 212, and the wire-passing hole can correspond one-to-one with the wire-passing groove.

[0085] In some embodiments, the at least one hinge may include a first hinge 141 and a second hinge 142, with the top edges of two adjacent solar panel units 210 connected to each other by the first hinge 141 and the bottom edges of two adjacent solar panel units 210 connected to each other by the second hinge 142.

[0086] Optionally, the top edges of adjacent solar panel units 210 can be interconnected by a plurality of first hinges 141. The plurality of first hinges 141 can be sequentially spaced along the top edges of the solar panel units 210 to improve the connection strength between the solar panel units 210. For example, the top edges of adjacent solar panel units 210 can be interconnected by two first hinges 141, which can be respectively located at both ends near the top edges of the solar panel units 210. Similarly, the bottom edges of adjacent solar panel units 210 can also be interconnected by a plurality of second hinges 142, which can also be sequentially spaced along the bottom edges of the solar panel units 210. When multiple first hinges 141 are provided between the top edges of adjacent solar panel units 210 and multiple second hinges 142 are provided between the bottom edges of adjacent solar panel units 210, the multiple first hinges 141 and multiple second hinges 142 can also constrain the movement direction of the solar panel units 210, ensuring that the solar module 200 moves approximately in a straight line during the folding or stretching process, avoiding deviation to the sides, and improving the stability of the solar module 200.

[0087] Optionally, the first hinge 141 may be the hinge 100 as described in any of the above embodiments, and the second hinge 142 may also be the hinge 100 as described in any of the above embodiments. For example, the first hinge 141 may be the hinge 100 as described in the first embodiment, and the second hinge 142 may be the hinge 100 as described in the second embodiment. Since the hinge 100 in the first embodiment is provided with a first stop 124 on the hinge member 120, when adjacent solar panel units 210 are unfolded at a certain angle, the first stop 124 on the two hinge members 120 can stop each other, thereby restricting the solar panel unit 210 from continuing to unfold, and also enabling the solar panel unit 210 to maintain its current unfolded state. This eliminates the need for structures such as auxiliary supports to maintain the unfolded posture of the solar panel unit 210, which is beneficial to simplifying the overall structure and reducing the production cost of the solar module 200.

[0088] It is understood that the first hinge 141 and the second hinge 142 may also adopt the structure of other embodiments. For example, the first hinge 141 may also adopt the structure of the third embodiment above, and the second hinge 142 may also adopt the structure of the fourth embodiment above.

[0089] Cooperate Figures 5 to 7 As shown, in some embodiments, the second hinge 142 further includes a first roller 150, which is rotatably connected to the hinge shaft 110 of the second hinge 142. That is, the first roller 150 is provided on the hinge 100 connected to the bottom edge of the adjacent solar panel unit 210. In this way, the first roller 150 slides along the ground during the folding or unfolding of the solar panel 200, which not only reduces resistance and makes the folding and unfolding of the solar panel 200 more effortless, but also avoids damage caused by friction or impact between the solar panel unit 210 and the ground.

[0090] Optionally, the second hinge 142 may include a hinge shaft 110 and two hinge members 120. Each hinge member 120 may include a base 126 and two opposing hinge arms 121, with a gap between the two opposing hinge arms 121. One end of each hinge arm 121 may be connected to the base 126. The first roller 150 may be disposed within the gap, and the hinge shaft 110 may pass through four hinge arms 121 and the first roller 150. Thus, the second hinge 142 functions as both the hinge 100 and the roller support, simplifying the structure and reducing production costs.

[0091] In some embodiments, two adjacent second hinges 142 in the extension direction of the solar module 200 are misaligned in the axial direction of the hinge shaft 110. Similarly, two adjacent first rollers 150 in the extension direction are also misaligned in the axial direction of the hinge shaft 110. Figure 15 and 16 As shown, this design avoids limiting the folding angle of the solar panel unit 210 due to interference between two adjacent first rollers 150 in the extension direction, and also provides relatively sufficient installation space for the first rollers 150, so that rollers with relatively large diameters can be selected, which is beneficial to improving stability.

[0092] In some embodiments, the solar panel unit 210 is provided with a flexible buffer block 220. When two adjacent solar panel units 210 are folded to a second target angle, the flexible buffer block 220 on one solar panel unit 210 can abut against the flexible buffer block 220 on another solar panel unit 210. In this way, damage to adjacent solar panel units 210 due to collision can be avoided.

[0093] Optionally, the second target angle can be the angle at which two adjacent solar substrates are folded to be parallel or nearly parallel to each other, such as... Figure 16As shown. For example, the second target angle can be 0° or close to 0°.

[0094] Optionally, the flexible buffer block 220 may be frustum-shaped. The flexible buffer block 220 may be disposed on the frame 211 of the solar panel unit 210. For example, multiple flexible buffer blocks 220 may be sequentially spaced along the frame 211 to adequately protect the solar panel 217. Optionally, the flexible buffer block 220 may be formed from rubber blocks, silicone blocks, and / or other flexible material blocks.

[0095] Cooperate Figure 13 and Figure 14 As shown, in some embodiments, the solar panel 200 further includes a protective plate 230, which is connected to the first solar panel unit 210 and / or the last solar panel unit 210 of a plurality of sequentially arranged solar panels via a hinge 100. For example, the solar panel 200 may include two protective plates 230, one of which is connected to the first solar panel unit 210 via a hinge 100, and the other of which is connected to the last solar panel unit 210 via a hinge 100, thus protecting the solar panel assembly from opposite sides. Of course, the solar panel 200 may also include a single protective plate 230, which may be connected to either the first or the last solar panel unit 210.

[0096] Optionally, the protective plate 230 can be formed from a non-porous material. For example, it can be made of steel plate or organic material. Alternatively, the protective plate 230 can also be formed from a mesh or grid, as long as it can adequately protect the solar panel unit 210.

[0097] Optionally, a handle may be provided on the protective plate 230. For example, the bottom edge of the protective plate 230 may be connected to the first solar panel unit 210 or the last solar panel unit 210 via a second hinge 142, and a handle may be provided on the top edge of the protective plate 230 to facilitate the user to extend the solar module 200 by pulling the handle.

[0098] In some embodiments, the protective plate 230 has a support leg 231 on the side facing away from the solar panel. One end of the support leg 231 is rotatably connected to the protective plate 230, and the other end of the support leg has a second roller 232. When unfolding the solar module 200, the support leg 231 can first be rotated to an approximately perpendicular position to the protective plate 230, and the second roller 232 can be brought into contact with the ground, such as... Figure 13As shown. The user can extend the solar panel 200 by pulling the protective plate 230, avoiding the user bearing the weight of the protective plate 230 and making it easier for the user to unfold the solar panel 200, thus improving the user experience. Furthermore, the support legs 231 prevent the protective plate 230 from scraping or bumping against the ground. When the solar panel 200 is in the folded state, the support legs 231 can be rotated to be close to the protective plate 230, preventing the support legs 231 from taking up space. Figure 14 As shown. Optionally, a support leg 231 may be provided on each of the two sides near the edge of the guard plate 230 to stably support the guard plate 230.

[0099] In some embodiments, the protective plate 230 has a cable reel 233 on the side facing away from the solar panel. During the extension of the solar module 200, the rotatable cable reel 233 releases the cable; during the folding of the solar module 200, the rotatable cable reel 233 winds the cable. This prevents the cable from interfering with the folding of the solar panel unit 210 and also prevents the cable from being scattered and piled up, improving the neatness of the solar module 200. Optionally, multiple cable reels 233 can be provided as needed.

[0100] This application also provides a solar energy device, including the solar module 200 as described in any of the above embodiments. Because adjacent solar panel units 210 of the solar module 200 can be folded to a parallel or nearly parallel state, and collisions or interference are less likely to occur, the solar module 200 has a small size in its folded state, resulting in higher transportation and storage convenience and lower transportation and storage costs. Therefore, the solar energy device using the solar module 200 also has the aforementioned advantages.

[0101] Optionally, the solar energy device may include one set of the solar energy modules 200, or multiple sets of the solar energy modules 200.

[0102] Optionally, the solar energy device may also include, for example, a controller, an energy storage device, and an inverter. The controller is used to control the operation of the solar energy modules, the energy storage device, and the inverter. The energy storage device is used to store electrical energy. The inverter is used to convert direct current (DC) into alternating current (AC). Of course, in practical applications, the inverter and the energy storage device may be omitted depending on actual needs.

[0103] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
