Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel technology, specifically to a foldable adjustable photovoltaic module. Background Technology

[0002] As is widely known, photovoltaic panels are a type of power generation equipment that uses the electronic properties of semiconductor materials to convert solar energy into electrical energy. They have many advantages, such as being environmentally friendly, energy-saving, and having a long lifespan.

[0003] For example, the invention patent with publication number CN117200673B, publication date November 29, 2024, entitled "An Adjustable Photovoltaic Solar Panel Support", includes a fixed base. Four symmetrically distributed support rods are fixedly arranged at the middle of the upper surface of the fixed base. A photovoltaic panel support deployment mechanism is arranged above the four support rods. The photovoltaic panel support deployment mechanism includes a power actuation component and a rotating bracket. One end of the rotating bracket is located between the top ends of two adjacent support rods, and a pin is inserted through the end. Both ends of the pin are rotatably inserted into the end sidewalls of the support rods. Photovoltaic panel mounting plates are arranged on both sides of the rotating bracket away from the support rods. Assembled photovoltaic panels are fixedly arranged on the surface of the photovoltaic panel mounting plates. A connecting shaft is inserted through the end of the photovoltaic panel mounting plates near the rotating bracket. A photovoltaic panel opening and closing mechanism is arranged at the end of the rotating bracket away from the support rods. The rotating bracket moves in a fan shape under the drive of the power actuation component, and the assembled photovoltaic panels rotate and open / close under the drive of the photovoltaic panel opening and closing mechanism during the movement of the rotating bracket.

[0004] The shortcomings of existing technologies are that, in order to ensure the power generation of photovoltaic panels, they usually need to be made into large sizes. However, large-sized photovoltaic panels are inconvenient to carry and transport. Although foldable photovoltaic panels already exist, existing foldable photovoltaic panels are simply made into multiple smaller photovoltaic panels of the same shape after being made into a large-sized photovoltaic panel. Therefore, they still occupy a lot of space after being folded. Moreover, photovoltaic panels cannot be bent or subjected to pressure, which further increases the risk of carrying and transporting photovoltaic panels. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable adjustable photovoltaic module to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable adjustable photovoltaic module, comprising a second and fourth plate in the shape of an isosceles trapezoid, a third and fifth plate in the shape of a triangle, and a first plate in the shape of a pentagon. Two second plates are located in the middle and their lower bases are hinged together.

The bases of two pairs of fifth plates are equal in length to the sides of the fourth plates and are hinged together. The right-angled sides of two adjacent fifth plates are hinged together. The bases of two pairs of third plates are equal in length to the bases of the fourth plates and are hinged together. The first plate is located between two adjacent third plates and its hypotenuses on opposite sides are equal in length to the right-angled sides of the third plates and are hinged together. The first plate, second plate, third plate, fourth plate, and fifth plate are combined to form a photovoltaic panel.

[0007] As a further description of the above technical solution: the photovoltaic panel includes the following three states:

[0009] In the second state, the photovoltaic panel is folded up and multiple components are folded up between the two first panels, with the back of the first panels facing outwards;

[0010] In the third state, the included angle between the two first plates is 160° and the remaining components are folded into an arc shape, and there is a recess between the two second plates.

[0011] As a further description of the above technical solution: it also includes a slide bar, and a connecting strip is provided on the back of the two first plates. The slide bar is provided with a first slide bar and a second slide bar extending into the interior of the connecting strip.

[0016] As a further description of the above technical solution: the extension rod is movably provided with a second locking block for locking the second slide bar and a fixing block for locking the second locking block.

[0017] As a further description of the above technical solution: the fixing block is cut off to move the second locking block and the second sliding rod, so that the photovoltaic panel switches from the first state to the third state.

[0018] As a further description of the above technical solution: the back of the first plate is provided with anti-collision armor.

[0019] In the above technical solution, the foldable adjustable photovoltaic module provided by the present invention has the following beneficial effects: when folded, the back sides of the two second panels are attached together, the front side of the fourth panel is attached to the front sides of both the second and fifth panels, the front side of the third panel is attached to the front side of the first panel, the back side of the third panel is attached to the back side of the second panel, and the back sides of two adjacent fifth panels are attached together.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-11 This invention provides a technical solution: a foldable adjustable photovoltaic module, comprising a second plate 22 and a fourth plate 24 in the shape of an isosceles trapezoid, a third plate 23 and a fifth plate 25 in the shape of a triangle, and a first plate 21 in the shape of a pentagon. The two second plates 22 are located in the middle and their lower bases are hinged together. The sides of the two pairs of fourth plates 24 are equal in length to the sides of the two second plates 22 and are hinged together. The bases of the two pairs of fifth plates 25 are equal in length to the sides of the fourth plates 24 and are hinged together. The right-angled sides of two adjacent fifth plates 25 are hinged together. The bases of the two pairs of third plates 23 are equal in length to the bases of the fourth plates 24 and are hinged together. The first plate 21 is located between two adjacent third plates 23 and its hypotenuses on opposite sides are equal in length to the right-angled sides of the third plates 23 and are hinged together. The first plate 21, the second plate 22, the third plate 23, the fourth plate 24 and the fifth plate 25 are combined to form a photovoltaic panel 2.

[0036] Specifically, when folding, the backs of the two second panels 22 are pressed together, the front of the fourth panel 24 is pressed together with the fronts of both the second panel 22 and the fifth panel 25, the front of the third panel 23 is pressed together with the front of the first panel 21, the back of the third panel 23 is pressed together with the back of the second panel 22, and the backs of the two adjacent fifth panels 25 are pressed together. After folding, only the backs of the two first panels 21 face outwards, which greatly reduces the possibility of damage to the photovoltaic panel 2. The folded photovoltaic panel 2 occupies less space and has a more square shape, making it easier to carry and transport.

[0037] In another embodiment of the present invention, the photovoltaic panel 2 includes the following three states:

[0038] In the first state, the multiple components of photovoltaic panel 2 are on the same plane;

[0039] In the second state, the photovoltaic panel 2 is folded up and multiple components are folded up between the two first panels 21, with the back of the first panels 21 facing outward;

[0040] In the third state, the included angle between the two first plates 21 is 160° and the remaining components are folded into an arc shape, and there is a recess between the two second plates 22.

[0041] Specifically, during operation, the photovoltaic panel 2 is in its first state, with its multiple components on the same plane, increasing the area exposed to sunlight and thus increasing its power generation. When transporting, the photovoltaic panel 2 can be folded and stored, changing it from the first state to the second state. The multiple components of the photovoltaic panel 2 are gathered between the two first panels 21, forming a more square shape for easy carrying and transport, with the back of the first panels 21 facing outwards to protect the middle section. When the photovoltaic panel 2 needs to be used and the wind speed is high, the first panels 21 can be rotated and initially folded, making the angle between the two first panels 21 160°. At this point, the photovoltaic panel 2 is in its third state, with the back of the photovoltaic panel 2 curved, which better guides the airflow to the outside of the photovoltaic panel 2, preventing it from being blown over.

[0042] In another embodiment of the present invention, a sliding rod is also included, and a connecting strip 26 is provided on the back of the two first plates 21, and a first sliding rod 27 and a second sliding rod 28 are provided on the sliding rod extending into the connecting strip 26.

[0043] Specifically, both the first slide bar 27 and the second slide bar 28 are provided with tenons extending into the interior of the connecting strip 26. The connecting strip 26 extends beyond the boundary of the first plate 21 to the rear of the second plate 22 without connecting to the second plate 22. The connecting strip 26 is provided with a mortise that matches the tenon, and the end of the mortise (the end near the middle of the photovoltaic panel 2 is the end) is provided with a notch that matches the tenon.

[0044] Furthermore, when operation is required, the folded photovoltaic panel 2 is placed between the first slide bar 27 and the second slide bar 28, and the two tenons on the first slide bar 27 and the second slide bar 28 are respectively inserted into the tenons of the two connecting bars 26. The first slide bar 27 and the second slide bar 28 are manually pushed away from each other and rotated, so that the two first panels 21 are moved away from each other, thereby causing the photovoltaic panel 2 to gradually unfold. The tenons move along the sliding grooves on the connecting bars 26 until the two tenons are located at the tail ends of the tenons of the two connecting bars 26. At this time, the photovoltaic panel 2 is fully unfolded, and the first slide bar 27 and the second slide bar 28 are located at the two ends of the slide bar, so that the photovoltaic panel 2 is kept in the unfolded state, ensuring a larger light-receiving area of ​​the photovoltaic panel 2 and ensuring power generation.

[0045] In another embodiment of the present invention, a push rod 29 is provided on the slide rod between the first slide rod 27 and the second slide rod 28, and a connecting plate 291 is provided on the push rod 29 to magnetically engage with the two second plates 22.

[0046] Specifically, during the movement of the first slide bar 27 and the second slide bar 28 (during this process, the tenon is located at the end of the connecting strip 26, and this location is on the outside of the photovoltaic panel 2 in the retracted state, so it will not interfere with the unfolding of the photovoltaic panel 2), the push rod 29 is manually pushed to move along the slide bar and gradually move to the middle of the photovoltaic panel 2. After the photovoltaic panel 2 is fully unfolded, the connecting plate 291 on the push rod 29 magnetically engages with the back of the two second plates 22, so that the two second plates 22 are on the same plane. Moreover, the first slide bar 27, the second slide bar 28 and the push rod 29 are on the same plane. The three work together to flatten the photovoltaic panel 2, so that the multiple components of the photovoltaic panel 2 are on the same plane.

[0047] In another embodiment of the present invention, a support frame 1 for supporting the slide bar is further included, and a tie rod 122 is provided between the support frame 1 and the push rod 29.

[0048] Specifically, the support frame 1 includes two parallel fixed rods 12, and two telescopic plates 121 are arranged between the fixed rods 12. A diagonal tie rod 122 is rotatably arranged in the middle of one of the telescopic plates 121, and a fixing hole is opened on the fixed rod 12 to facilitate the passage of ground nails.

[0049] Furthermore, the diagonal tie rod 122 is specifically a threaded telescopic rod. A U-shaped clip 124 is provided at the end of the diagonal tie rod 122. A cylindrical block 125 is symmetrically slidably arranged inside the U-shaped clip 124. A slope is provided on one side wall of the cylindrical block 125. A spring is provided between the cylindrical block 125 and the U-shaped clip 124. A groove adapted to the cylindrical block 125 is provided on the push rod 29. A pressure block 126 is slidably arranged on the U-shaped clip 124. A third cable 127 is provided between the pressure block 126 and the cylindrical block 125. An L-shaped fixing plate 123 is provided on the side wall of the two adjacent support frames 1. A through hole adapted to the cylindrical block 125 is provided on the fixing plate 123. A shaft extending into the fixing rod 12 is provided at both ends of the sliding rod.

[0050] Furthermore, during operation, the two fixed rods 12 are pulled apart, and the sliding rod carrying the unfolded photovoltaic panel 2 is placed between the two fixed rods 12. Then, the fixed rods 12 are manually pushed together, causing the sliding rod to rotate and install onto the fixed rods 12. Next, the inclined pull rod 122 is pushed, causing the cylindrical block 125 on the U-shaped clip 124 to abut against the push rod 29. The push rod 29 pushes against the inclined surface of the cylindrical block 125, causing the cylindrical block 125 to retract into the U-shaped clip 124 until the cylindrical block 125 is aligned with the groove on the push rod 29. At this point, the cylindrical block 125 is pushed by the spring into the push rod 29, fixing the push rod 29 and the U-shaped clip 124 together. The inclined pull rod 122, the push rod 29, the sliding rod, and the fixed rod 12 combine to form a pyramid-shaped support, which can stably support the photovoltaic panel. 2. It can not only block the airflow from the front and back, but also has a good effect against crosswinds. Then, rotate the middle of the diagonal rod 122 to change the length of the diagonal rod 122, thereby adjusting the tilt angle of the photovoltaic panel 2 so that the photovoltaic panel 2 can face the sun better. When it is necessary to retract the photovoltaic panel 2, press the pressure block 126. The pressure block 126 drives the cylindrical block 125 to retract into the U-shaped card 124 through the third cable 127, so that the U-shaped card 124 is separated from the push rod 29. Then, take out the sliding rod and the photovoltaic panel 2 from between the fixed rods 12, and push the two fixed rods 12 together, and the two L-shaped fixed plates 123 together. Then push the diagonal rod 122 so that the U-shaped card 124 is fixed on the two fixed plates 123, thereby fixing the fixed rods 12 and the diagonal rod 122 together.

[0051] In another embodiment of the present invention, the slide bar is formed by inserting and connecting an extension bar 112 and a mounting bar 111 for limiting the second slide bar 28, and the slide bar is coupled to the support frame 1 to unlock the second slide bar 28.

[0052] Specifically, both the mounting rod 111 and the extension rod 112 are provided with mortises. The bottom of the second slide rod 28 is provided with a disc that matches the mortises. The push plate is also provided with a tenon that matches the mortises. The first slide rod 27 is rotatably mounted on the mounting rod 111. The mortises on the mounting rod 111 are slidably provided with a stop block 132. A spring is provided between the stop block 132 and the mounting rod 111. The extension rod 112 is provided with an insert block 131. The mounting rod 111 is provided with a groove that matches the insert block 131. The stop block 132 is provided with a connecting rod 133 that extends into the groove.

[0053] Furthermore, a triangular prism-shaped first locking block 113 is provided on the mounting rod 111, and a groove adapted to the first locking block 113 is provided at the bottom of the first sliding rod 27. A spring is provided between the first locking block 113 and the mounting rod 111. A first wedge block 114 is slidably provided in the shaft on the side wall of the mounting rod 111. A spring is provided between the first wedge block 114 and the shaft. A first cable 136 is provided between the first wedge block 114 and the first locking block 113.

[0054] Furthermore, when the mounting rod 111 is connected to the extension rod 112, the insert 131 on the extension rod 112 is aligned with the groove on the mounting rod 111, and the insert 131 is inserted into the mounting rod 111. The tenon on the mounting rod 111 is aligned with the tenon on the extension rod 112. The insert 131 presses against the connecting rod 133, thereby pushing the stop 132 to retract into the mounting rod 111, so that the second slide rod 28 can pass through the tenon on the mounting rod 111 and move into the extension rod 112. After use, the second slide rod 28 and the push rod 29 are manually pushed to retract into the mounting rod 111. Then the mounting rod 111 is separated from the extension rod 112, and the stop 132 extends under the action of the spring, thereby restricting the second slide rod 28 and the push rod 29 on the mounting rod 111.

[0055] Furthermore, when the shaft on the mounting rod 111 is inserted into the fixing rod 12, the side wall of the groove on the fixing rod 12 pushes against the inclined surface of the first wedge block 114, causing the first wedge block 114 to retract into the shaft. The first cable 136 is released, and the first locking block 113 moves upward under the action of the spring and inserts into the first slide rod 27, fixing the first slide rod 27 to the mounting rod 111. When the mounting rod 111 is separated from the fixing rod 12, the first wedge block 114 moves outward under the push of the spring and pulls the first locking block 113 through the first cable 136, causing the first locking block 113 to separate from the first slide rod 27, and the first slide rod 27 is unlocked.

[0056] In another embodiment of the present invention, the second slide bar 28 is laterally moved to lock or unlock the mounting rod 111 with the extension rod 112.

[0057] Specifically, the mounting rod 111 is provided with an L-shaped insert rod 134, and a spring 135 is provided at the top of the insert rod 134.

[0058] Furthermore, as the second slide bar 28 moves from the mounting rod 111 into the extension rod 112, the disc at the bottom of the second slide bar 28 pushes the spring 135. The spring 135 drives the L-shaped insert rod 134 to move into the extension rod 112 until the insert rod 134 spans across the mounting rod 111 and the extension rod 112. The insert rod 134, in conjunction with the insert block 131, fixes the mounting rod 111 and the extension rod 112 together, keeping the mounting rod 111 and the extension rod 112 on the same axis. This ensures that the first slide bar 27, the second slide bar 28, and the push rod 29 are on the same plane, thereby allowing light to pass through. The photovoltaic panel 2 remains unfolded into a flat state to ensure a large light-receiving area and power generation. The second slide bar 28 continues to move, and the spring 135 is compressed and deformed, thus separating from the second slide bar 28. After the second slide bar 28 leaves, the spring 135 returns to its upright state under its own elastic force. When the second slide bar 28 moves from the extension bar 112 into the mounting bar 111, the second slide bar 28 pushes the insertion rod 134 to move in the opposite direction through the spring 135, causing the insertion rod 134 to retract into the mounting bar 111, thereby unlocking the mounting bar 111 from the extension bar 112.

[0059] In another embodiment of the present invention, a second locking block 116 for locking the second slide bar 28 and a fixing block 118 for locking the second locking block 116 are movably disposed in the extension rod 112.

[0060] Specifically, a movable plate 115 is slidably mounted on the extension rod 112, and a groove adapted to the movable plate 115 is provided in the tenon of the extension rod 112. Fixed blocks 118 extending into the extension rod 112 are symmetrically arranged on the movable plate 115. The second locking block 116 is cylindrical and slidably mounted on the movable plate 115. A cylindrical groove adapted to the second locking block 116 is provided on the disc at the bottom of the second sliding rod 28. A spring is provided between the second locking block 116 and the movable plate 115. A ramp is provided on the side wall of the second locking block 116. A second wedge 117 is slidably mounted in the shaft on the side wall of the extension rod 112. A spring is provided between the second wedge 117 and the shaft. A magnet 119 for attracting the second locking block 116 is slidably mounted on the extension rod 112. A spring is provided between the magnet 119 and the extension rod 112. A second cable 137 is provided between the magnet 119 and the second wedge 117.

[0061] Furthermore, when the shaft on the extension rod 112 is inserted into the fixed rod 12, the second wedge 117 on the shaft of the extension rod 112 is pushed and moves inward. The second wedge 117 pulls the magnet 119 away from the movable plate 115 through the second cable 137. The magnet 119 no longer attracts the second locking block 116. The second locking block 116 moves upward under the push of the spring and inserts into the second slide rod 28, thereby fixing the second slide rod 28 to the extension rod 112. When the shaft on the extension rod 112 leaves the fixed rod 12, the second wedge 117 moves outward under the action of the spring. The second cable 137 is released, and the magnet 119 moves upward under the push of the spring and attracts the second locking block 116, causing the second locking block 116 to retract into the movable plate 115, and the second slide rod 28 is unlocked.

[0062] In another embodiment of the present invention, the fixing block 118 is cut off to move the second locking block 116 and the second slide bar 28, so that the photovoltaic panel 2 switches from the first state to the third state.

[0063] Specifically, when the front of the photovoltaic panel 2 in the first state encounters a strong airflow, the tilted photovoltaic panel 2 can guide the airflow to move obliquely upwards without affecting the normal operation of the photovoltaic panel 2. At this time, the fixing block 118 fixes the movable plate 115, and then fixes the second sliding rod 28, so that the photovoltaic panel 2 remains unfolded into a flat state, ensuring a large light-receiving area of ​​the photovoltaic panel 2 and ensuring power generation. When the back of the photovoltaic panel 2 in the first state encounters a strong airflow, the airflow will continuously blow the photovoltaic panel 2, and the fixing block 118 will be cut off under continuous stress. At this time, the movable plate 115 and the second locking block 116 can move along the groove inside the extension rod 112. The second slide rod 28 can move closer to the first slide rod 27 and rotate relative to the extension rod 112, so that the two first plates 21 rotate relative to each other. The photovoltaic panel 2 changes from the first state to the third state. At this time, the arc-shaped back of the photovoltaic panel 2 can better guide the airflow. At this time, the indentation formed by the two second plates 22 on the back of the photovoltaic panel 2 can guide some airflow to leave through the gap between the two second plates 22. The high-speed airflow will make a sharp whistling sound when passing through the slit, reminding the user to put the photovoltaic panel 2 away.

[0064] Furthermore, the fixing block 118 in the above embodiment is specifically a lead-tin alloy that is easy to cut.

[0065] In another embodiment of the present invention, the back of the first plate 21 is provided with anti-collision armor.

[0066] Specifically, when the photovoltaic panel 2 is in the retracted state, the two first plates 21 protect multiple components of the photovoltaic panel 2 in the center, and the back of the first plates 21 faces outward. The anti-collision armor on the back of the first plates 21 can greatly improve the overall anti-collision capability of the photovoltaic panel 2.

[0067] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

The photovoltaic panel includes the following three states: In the first state, the multiple components of the photovoltaic panel are on the same plane; In the second state, the photovoltaic panel is folded up and multiple components are folded up between the two first panels, with the back of the first panels facing outwards; In the third state, the included angle between the two first plates is 160° and the remaining components are gathered into an arc shape, and there is a recess between the two second plates; It also includes a slide bar, and a connecting strip is provided on the back of the two first plates. The slide bar is provided with a first slide bar and a second slide bar extending into the interior of the connecting strip. The slide bar is provided with a push rod located between the first slide bar and the second slide bar, and the push rod is provided with a connecting plate that magnetically engages with the two second plates; It also includes a support frame for supporting the slide bar, and a diagonal tie rod is provided between the support frame and the push rod; The slide bar is composed of an extension bar and a mounting bar for limiting the second slide bar, and the slide bar is coupled to the support frame to unlock the second slide bar; The extension rod is movably provided with a second locking block for locking the second slide rod and a fixing block for locking the second locking block. A movable plate is slidably provided on the extension rod. A groove adapted to the movable plate is opened in the tenon groove of the extension rod. Fixing blocks extending into the extension rod are symmetrically arranged on the movable plate. The second locking block is specifically cylindrical and slidably installed on the movable plate. A cylindrical groove adapted to the second locking block is opened on the disc at the bottom of the second slide rod. A spring is provided between the second locking block and the movable plate. A ramp is provided on the side wall of the second locking block. A second wedge is slidably provided in the shaft on the side wall of the extension rod. A spring is provided between the second wedge and the shaft. A magnet for attracting the second locking block is slidably provided on the extension rod. A spring is provided between the magnet and the extension rod. A second cable is provided between the magnet and the second wedge. When there is a strong airflow, the airflow will continuously blow the photovoltaic panel, and the fixing block will be cut off under continuous stress. The cutting off of the fixing block will cause the second locking block and the second sliding rod to move, so that the photovoltaic panel will switch from the first state to the third state.
