[0001] The present application relates to the technical field of photovoltaic products, and in particular to a hinge, a solar module and a solar device. Background Art

[0002] Foldable solar panels typically consist of multiple solar panels connected by a rotating pair. During transport, the system can be folded, resulting in a smaller size and easier transport. During deployment, the panels can be unfolded, offering higher power generation and easier deployment. However, due to the limitations of the rotating pair structure, adjacent solar panels are prone to interference and collision during folding, potentially damaging them. Furthermore, the compactness of the folded solar panel needs to be improved.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] Referring to Figures 1 to 4, an embodiment of the present application provides a hinge 100, which includes a hinge shaft 110 and two hinged parts 120 hinged to each other through the hinge shaft 110. The hinge part 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 is bent relative to the first hinge portion 122 in the folding direction of the hinge part 120, and the second hinge portion 123 is used to connect to an external object. Optionally, the first hinge portion 122 and the second hinge portion 123 can adopt an integrated structure, or can be formed by being fixedly connected to each other through a split structure. The second hinge portion 123 is used to connect to an external object, including both direct and indirect connections.

[0047] The folding direction is the direction of movement of the hinge 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 120 during the unfolding process of the hinge 100. Taking the hinge shown in Figure 1 as an example, the folding direction and unfolding direction of the hinge on the left side of Figure 1 are counterclockwise and clockwise, respectively, while the folding direction and unfolding direction of the hinge on the right side of Figure 1 are clockwise and counterclockwise, respectively.

[0048] In fact, one end of the two hinged parts 120 can be hinged to each other through the hinge shaft 110, and a part of the hinged part 120 close to the hinge shaft 110 forms the first hinge part 122, and a part of the hinged part 120 away from the hinge shaft 110 is bent relative to the first hinge part 122 in the folding direction of the hinged part 120 to form the second hinge part 123.

[0049] When the two second hinge parts 123 rotate to a state parallel to or nearly parallel to each other, the two first hinge parts 122 gradually move away from each other in the process of extending from the hinge axis 110 to the second hinge part 123, forming a spacing and the spacing gradually increases until it connects with the second hinge part 123, as shown in Figures 1 and 2, providing avoidance space for the two second hinge parts 123, and also providing avoidance space for the two external objects connected to the second hinge part 123, so that the two external objects can rotate to a state parallel to or nearly parallel to each other, which not only improves the compactness of the two external objects in the folded state, but also avoids interference and collision between the external objects.

[0050] For example, if two solar panel units 210 are connected via the hinge 100, the two solar panel units 210 can be folded until they are parallel or nearly parallel to each other, which improves the compactness of the folded solar panel units 210 and reduces the space they occupy. Furthermore, 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 interference or collision can be avoided.

[0051] It should be noted that the external object may include various objects that need to be rotatably connected to another object through the hinge 100, not limited to the solar panel unit 210, and the type of objects connected to each other through the hinge 100 is not limited here.

[0052] In actual 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, as shown in the first embodiment in Figures 1 to 4. For another example, the second hinge portion 123 can be bent at a relatively small angle relative to the first hinge portion 122, so that the first hinge portion 122 and the second hinge portion 123 form an obtuse angle, as shown in the second embodiment in Figures 5 to 7 and the third embodiment in Figures 8 to 10.

[0053] As shown in Figures 1 to 4 , in some embodiments, at least one of the hinges 120 is provided with a first stopper 124. The first stopper 124 is configured to stop another first stopper 124 or another hinge 120 when the two hinges 120 are extended to a first target angle, thereby limiting further extension of the two hinges 120, as shown in Figures 3 and 4 . In this way, the two external objects can be prevented from over-extending and their current postures can be maintained.

[0054] Optionally, the first stop portion 124 may be provided on one of the hinges 120 , and the first stop portion 124 may be configured to stop the other hinge 120 when the two hinges 120 are unfolded to the first target angle, thereby limiting the further unfolding of the two hinges 120 .

[0055] Optionally, a first stopper 124 may be provided on each of the two hinges 120. The two first stoppers 124 may be configured to stop each other when the two hinges 120 are unfolded to the first target angle, so as to limit the further unfolding of the two hinges 120.

[0056] Optionally, the first stop portion 124 can be constructed to stop each other with another first stop portion 124 or another hinge 120 when the two first hinge portions 122 are unfolded to the first target angle, and can also stop each other with another first stop portion 124 or another hinge 120 when the two second hinge portions 123 are unfolded to the first target angle.

[0057] Optionally, the first target angle may be any angle between 0° and 360°. For example, the first target angle may be any angle between 0° and 180°, with reference to the inner contour or outer contour of the second hinge portion 123 .

[0058] In some embodiments, one end of the second hinge portion 123 connected to the first hinge portion 122 protrudes from the first hinge portion 122 to form a first stop 124. For example, one end of the second hinge portion 123 may protrude from the first hinge portion 122 to form a first stop 124 with a trapezoidal longitudinal cross-section, as shown in Figures 1 to 4. When the two hinged members 120 are deployed to the first target angle, the waists of the two trapezoidal shapes in the longitudinal cross-section abut against each other, limiting further deployment of the two hinged members 120, as shown in Figures 3 and 4. Of course, the longitudinal cross-section of the first stop 124 can be configured in any shape, such as a hemispherical shape, a semi-cylindrical shape, etc., and is not limited to a trapezoidal shape.

[0059] In some embodiments, a boss is provided on one side of the first hinge portion 122 facing the direction of expansion of the hinge member 120, forming the first stop 124. The expansion direction is the direction of movement of the hinge member 120 during the transition of the hinge 100 from the folded state to the expanded state. Alternatively, the boss may be provided on the first hinge portion 122 near the hinge axis 110 or near the second hinge portion 123.

[0060] It should be noted that, in specific implementation, the first stopper 124 can be implemented in a variety of ways and should not be construed as being limited to the above-mentioned embodiment. For example, a stopper arm that can interfere with another hinge 120 can be provided on one hinge 120 .

[0061] In some embodiments, at least one of the hinges 120 is provided with a second stopper (not shown in the figures). The second stopper is configured to stop the second stopper or another hinge 120 when the two hinges 120 are folded to a second target angle, thereby limiting further folding of the two hinges 120. This prevents interference between the two hinges 120 and collision between two external objects connected by the hinge 100.

[0062] Optionally, with the second hinge portion 123 as a reference, the second target angle may be 0° or an angle close to 0°. Thus, when the two second hinge portions 123 rotate to become parallel or nearly parallel to each other, the second stopper restricts the two hinge members 120 from further folding, thereby preventing collision with external objects. With the first hinge portion 122 as a reference, the second target angle may 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.

[0063] Optionally, the second stop portion may be provided on the first hinge portion 122 or the second hinge portion 123. The second stop portion may be formed by a stop block or a stop arm. For example, a flexible stop block may be provided on one side of the second hinge portion 123 facing the folding direction. The 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 further folding of the two hinge members 120.

[0064] As shown in FIG2 , in some embodiments, the hinge 100 further includes an elastic member 130 connected between the two hinged members 120. The elastic member 130 is configured to apply elastic force to the hinged members 120 during the unfolding or folding process of the two hinged members 120, thereby slowing down the unfolding or folding speed of the hinged members 120. This improves the stability of the hinge 100 during the unfolding or folding process, preventing collisions between external objects connected by the hinge 100. It also provides a buffering force for the hinge 100 itself, preventing damage caused by excessive instantaneous impact due to excessive movement speed.

[0065] Optionally, the elastic member 130 may be configured to apply elastic force to each of the two hinges 120 in the unfolding direction. This can slow down the folding of the hinge 120 during the folding process of the hinge 100, preventing collision between the two hinges 120 or two external objects connected by the hinge 100. It can also assist in unfolding the hinge 100 during the unfolding process, making it easier for the user to unfold external objects connected by the hinge 100.

[0066] Optionally, the elastic member 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. The torsion spring may be configured to be in a compressed state. In this way, the torsion spring can apply elastic force to the two hinge members 120 in the expansion direction.

[0067] It should be noted that the elastic member 130 is not limited to a torsion spring, and other elastic members 130 may also be used. The elastic member 130 is not limited to being connected to the hinge shaft 110, and may also be set, for example, between the two first hinge parts 122 or between the two second hinge parts 123.

[0068] In specific implementation, the shape and structure of the hinge 120 can be realized in various ways. The specific shape and structure of the hinge 120 are exemplified below in combination with several specific embodiments, but it should not be understood that the hinge 120 is limited to the following structure.

[0069] As shown in Figures 1 to 4 , 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 or approximately perpendicular to each other. The cross-section of the second hinge portion 123 may be L-shaped or U-shaped, allowing the second hinge portion 123 to be wrapped around the outside of a rectangular profile.

[0070] 5 to 7 , in some embodiments, the hinge 120 may further include a base 126 , to which the other end of the second hinge portion 123 is connected, and the base 126 is used to connect to an external object. This facilitates connection of the hinge 120 to an external object.

[0071] Optionally, the hinged member may include a plurality of hinged arms 121 , wherein the plurality of hinged arms 121 are arranged in parallel, and the hinged arm 121 includes the first hinge portion 122 and the second hinge portion 123 .

[0072] Optionally, the hinged member 120 may include a base 126 and two hinged arms 121. The two hinged arms 121 may be plate-shaped with opposing plate surfaces. One end of each hinged arm 121 is connected to the base 126, and the other end of each hinged arm 121 is provided with an axis hole. The hinge shaft 110 is provided with an axis hole to hinge the two hinged members 120. A portion of the hinged arm 121 near the hinge shaft 110 may extend radially along the hinge shaft 110 to form the first hinge portion 122. A portion of the hinged arm 121 near the base 126 is bent relative to the first hinge portion 122 in a folding direction to form the second hinge portion 123.

[0073] Optionally, the hinged member 120 further includes one or more connecting parts, which are connected between the two hinged arms 121 to improve the structural strength and firmness of the hinged member 120 .

[0074] Optionally, the longitudinal cross-section of the base 126 may be U-shaped, and the base 126 as a whole may be U-shaped, as shown in the second embodiment in Figures 5 to 7, or as shown in the third embodiment in Figures 8 to 10, so that the base 126 can be wrapped around the outside of a structure such as a profile or frame 211 to facilitate connection between the base 126 and an external object.

[0075] Optionally, the longitudinal section of the base 126 may be L-shaped, as shown in the fourth embodiment in Figures 11 and 12, so that the base 126 can be punched on the outside of a structure such as a profile or frame 211 to facilitate connection of the base 126 with external objects.

[0076] Optionally, the base 126 has a notch 127, and the other end of the second hinged portion 123 has a protruding insertion portion 125 that fits into the notch 127. The other end of the second hinged portion 123 and the base 126 are welded together, as shown in the third embodiment in Figures 8 to 10. Alternatively, the other end of the first hinged portion 122 may have a notch 127, and the insertion portion 125 may be provided on the base 126, as shown in the fourth embodiment in Figures 11 and 12. This allows the base 126 and the hinged arm 121 to be securely welded together, thereby improving the stability and structural strength of the hinge 100.

[0077] 13 to 16 , an embodiment of the present application provides a solar panel assembly 200 comprising a plurality of solar panel units 210 and at least one hinge 100 as described in any of the above embodiments. The plurality of solar panel units 210 are arranged sequentially, with adjacent solar panel units 210 interconnected via the hinge 100. This allows adjacent solar panel units 210 to be folded to a position parallel or nearly parallel to each other, and are less likely to collide or interfere with each other, as shown in FIG16 . This helps reduce the size of the solar panel assembly 200 in its folded state, improves transportation and storage convenience, and reduces transportation and storage costs.

[0078] Optionally, the hinge 100 employed in the solar module 200 may be configured as described in the first embodiment above, with an elastic member 130, such as a torsion spring, disposed between the two hinged members 120 of the hinge 100. This elastic member can provide a buffering force during the folding or extension of the solar module 200, preventing collisions between adjacent solar panel units 210 and excessive instantaneous impact forces caused by excessive movement. Furthermore, the elastic member 130 can absorb external forces, preventing them from directly acting on the solar panel units 210 and improving the stability of the solar module 100.

[0079] As shown in Figures 17 and 18 , 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 a mounting location for the hinge 100. For example, in a case where the hinge 120 of the hinge 100 includes a base 126 having a U-shaped or L-shaped longitudinal cross-section, the U-shaped or L-shaped base 126 may be fastened to the frame 211 and connected to the frame 211 via connectors such as screws or rivets.

[0080] Optionally, the frame 211 may include a frame 212, and the solar panel 217 may be connected to the area enclosed by the frame 212. In this way, the frame 212 can fully protect the solar panel 217. Exemplarily, a ridge may be provided on the inner circumference of the frame 212, and the side edge of the solar panel 217 may overlap the ridge. The ridge may be formed by welding a C-shaped steel or a U-shaped steel to the inner circumference of the frame 212. Optionally, a handle may be provided on the side of the frame 212 to facilitate the user to fold or unfold the solar module 200 by pulling the handle. Optionally, the frame 212 may be rectangular, and the corresponding solar panel 217 may also be rectangular. Of course, the frame 212 and the solar panel 217 may also be in other shapes.

[0081] Optionally, the frame 211 may further include a plurality of reinforcing ribs 213, each of which may be connected to the frame 212 at both ends. The provision of the reinforcing ribs 213 not only further enhances the structural strength of the frame 211 but also provides more adequate support and protection for the solar panel 217. The reinforcing ribs 213 may extend laterally or vertically. When the reinforcing ribs 213 extend laterally, the plurality of reinforcing ribs 213 may be spaced apart vertically. When the reinforcing ribs 213 extend vertically, the plurality of reinforcing ribs 213 may be spaced apart laterally.

[0082] In some embodiments, a wire passage 214 is provided within the reinforcing rib 213 and / or the frame 212. The wire passage 214 extends through the outer periphery of the frame 212 to form a wire opening 215. The wire openings 215 on adjacent solar panel units 210 are arranged opposite each other. The wire passage 214 and the wire opening 215 are used to thread cables. For example, a cable connecting a solar panel 217 can be placed within the wire passage 214 and extended through the wire opening 215 into the wire passage 214 of another solar panel unit 210.

[0083] Optionally, the threading channel 214 may be provided in the frame 212. For example, the frame 212 may be a hollow structure, and the threading channel 214 is formed by the inner cavity of the frame 212. Optionally, the threading channel 214 may also be provided on the reinforcing rib 213. For example, as shown in FIG19 , the reinforcing rib 213 may extend vertically, and a threading groove may be provided on the reinforcing rib 213. The threading groove may extend along the length direction of the reinforcing rib 213 and pass through both ends of the reinforcing rib 213. The frame 212 may be provided with threading holes, and the threading holes may correspond one-to-one to the threading grooves.

[0084] In some embodiments, the at least one hinge may include a first hinge 141 and a second hinge 142, and the top edges of two adjacent solar panel units 210 may be connected to each other through the first hinge 141, and the bottom edges of two adjacent solar panel units 210 may be connected to each other through the second hinge 142.

[0085] Optionally, the top edges of adjacent solar panel units 210 may be connected to each other via multiple first hinges 141, which may be sequentially spaced along the top edges of the solar panel units 210 to enhance the connection strength between the solar panel units 210. For example, the top edges of adjacent solar panel units 210 may be connected to each other via two first hinges 141, which may be located at either end near the top edges of the solar panel units 210. Similarly, the bottom edges of adjacent solar panel units 210 may be connected to each other via multiple second hinges 142, which may also be sequentially spaced along the bottom edges of the solar panel units 210. When multiple first hinges 141 are set between the top edges of adjacent solar panel units 210 and multiple second hinges 142 are set between the bottom edges of adjacent solar panel units 210, the multiple first hinges 141 and the multiple second hinges 142 can also constrain the movement direction of the solar panel units 210, ensuring that the solar component 200 moves approximately in a straight line during folding or extending, avoiding deviation to both sides, and improving the stability of the solar component 200.

[0086] Optionally, the first hinge 141 may be the hinge 100 described in any of the above embodiments, and the second hinge 142 may also be the hinge 100 described in any of the above embodiments. For example, the first hinge 141 may be the hinge 100 described in the first embodiment, and the second hinge 142 may be the hinge 100 described in the second embodiment. Because the hinge 100 in the first embodiment is provided with a first stop 124 on the hinge 120, when adjacent solar panel units 210 are deployed to a certain angle, the first stop 124 on the two hinges 120 can stop each other, thereby limiting further deployment of the solar panel units 210 and maintaining the solar panel units 210 in their current deployed state. This eliminates the need for structures such as auxiliary brackets for maintaining the deployed solar panel units 210, thereby simplifying the overall structure and production costs of the solar module 200.

[0087] It is understood that the first hinge 141 and the second hinge 142 may also adopt the structures of other embodiments. For example, the first hinge 141 may also adopt the structure of the third embodiment, and the second hinge 142 may also adopt the structure of the fourth embodiment.

[0088] As shown in Figures 5 to 7 , 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. Specifically, the first roller 150 is provided on the hinge 100 connected to the bottom edge of the adjacent solar panel unit 210. This allows the first roller 150 to slide along the ground during folding or extending of the solar panel 200, reducing resistance and making folding and extending the solar panel 200 more labor-efficient. It also prevents damage to the solar panel unit 210 caused by friction or collision with the ground.

[0089] Optionally, the second hinge 142 may include a hinge shaft 110 and two hinged members 120. The hinged members 120 may include a base 126 and two opposing hinged arms 121. A gap may be defined between the two opposing hinged arms 121, and one end of each hinged 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 be threaded through the four hinged arms 121 and the first roller 150. In this manner, the second hinge 142 serves both the function of the hinge 100 and the function of a roller bracket, simplifying the structure and reducing production costs.

[0090] In some embodiments, two adjacent second hinges 142 in the extension direction of the solar module 200 are staggered along the axial direction of the hinge shaft 110. Thus, two adjacent first rollers 150 in the extension direction are also staggered along the axial direction of the hinge shaft 110, as shown in Figures 15 and 16. This prevents interference between the two adjacent first rollers 150 in the extension direction, which could limit the folding angle of the solar panel unit 210. Furthermore, sufficient installation space is provided for the first rollers 150, allowing for the use of rollers with relatively large diameters, which improves stability.

[0091] In some embodiments, the solar panel units 210 are provided with flexible buffer blocks 220. When two adjacent solar panel units 210 are folded to the second target angle, the flexible buffer block 220 on one solar panel unit 210 can abut against the other solar panel unit 210 or the flexible buffer block 220 on another solar panel unit 210. This can prevent damage to adjacent solar panel units 210 due to collision.

[0092] Optionally, the second target angle may be the angle at which two adjacent solar panels are folded to be parallel or nearly parallel to each other, as shown in Figure 16. For example, the second target angle may be 0° or an angle close to 0°.

[0093] Optionally, the flexible buffer block 220 may be truncated cone-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 fully protect the solar panel 217. Optionally, the flexible buffer block 220 may be formed from a rubber block, a silicone block, and / or other flexible material block.

[0094] As shown in Figures 13 and 14 , in some embodiments, the solar panel assembly 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 the plurality of sequentially arranged solar panels via the hinge 100. For example, the solar panel assembly 200 may include two protective plates 230, one protective plate 230 connected to the first solar panel unit 210 via the hinge 100, and the other protective plate 230 connected to the last solar panel unit 210 via the hinge 100, thereby protecting the solar panel assembly from opposite sides. Of course, the solar panel assembly 200 may also include a single protective plate 230, which can be connected to the first solar panel unit 210 or the last solar panel unit 210.

[0095] Optionally, the protective plate 230 may be formed of a non-porous plate, such as a steel plate or an organic plate. Alternatively, the protective plate 230 may be formed of a mesh plate or a grid plate, as long as it can fully protect the solar panel unit 210.

[0096] Optionally, a handle may be provided on the guard plate 230. For example, the bottom edge of the guard plate 230 may be connected to the first solar panel unit 210 or the last solar panel unit 210 via the second hinge 142, and a handle may be provided on the top edge of the guard plate 230 to facilitate the user to extend the solar module 200 by pulling the handle.

[0097] In some embodiments, a support leg 231 is provided on the side of the guard plate 230 facing away from the solar panel. One end of the support leg 231 is rotatably connected to the guard plate 230, and the other end of the support leg is provided with a second roller 232. When unfolding the solar panel 200, the support leg 231 can first be rotated to a position approximately perpendicular to the guard plate 230, and the second roller 232 is brought into contact with the ground, as shown in FIG13. By pulling the guard plate 230, the user can extend the solar panel 200, eliminating the need for the user to bear the weight of the guard plate 230. This reduces the user's effort when unfolding the solar panel 200, improving the user experience. The support leg 231 also prevents the guard plate 230 from rubbing against the ground. When the solar panel 200 is folded, the support leg 231 can be rotated to abut against the guard plate 230, preventing the support leg 231 from taking up space, as shown in FIG14. Optionally, a support leg 231 may be provided near both side edges of the guard plate 230 to stably support the guard plate 230 .

[0098] In some embodiments, a cable reel 233 is provided on the side of the protective plate 230 facing away from the solar panel. When the solar module 200 is extended, the cable reel 233 can be rotated to pay out the cable. When the solar module 200 is folded, the cable reel 233 can be rotated to reel in the cable. This prevents the cable from interfering with the folding of the solar panel unit 210 and prevents the cable from being scattered and stacked, thereby improving the neatness of the solar module 200. Optionally, multiple cable reels 233 may be provided as needed.

[0099] The present application also provides a solar device comprising a solar panel assembly 200 as described in any of the above embodiments. Because adjacent solar panel units 210 of the solar panel assembly 200 can be folded to a parallel or nearly parallel position, and are less likely to collide or interfere with each other, the solar panel assembly 200 is compact in size when folded, offering greater ease and lower costs for transportation and storage. Therefore, a solar device utilizing the solar panel assembly 200 also possesses the aforementioned advantages.

[0100] Optionally, the solar device may include one group of solar components 200 or multiple groups of solar components 200 .

[0101] Optionally, the solar panel may further include, for example, a controller, an energy storage device, and an inverter. The controller is used to control the operation of the solar panel, 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 actual applications, the inverter and energy storage device may be omitted based on actual needs.

[0102] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
