Description

Technical Field

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

[0002] A photovoltaic (PV) system is a device that generates electricity using solar energy. A typical PV system includes photovoltaic panels and a support frame. The support frame holds the photovoltaic panels at a certain angle to the external surface to improve power generation efficiency. However, the angle between the support frame and the photovoltaic panel is often fixed. Therefore, the photovoltaic panel can only maintain a fixed angle with the external surface. Since the angle of sunlight can change, the direction the photovoltaic panel faces cannot always correspond to the direction of sunlight, resulting in lower power generation efficiency for the PV system. Utility Model Content

[0003] To address the aforementioned technical problems, embodiments of this application provide a photovoltaic device, which includes photovoltaic modules and a support structure. The photovoltaic modules include photovoltaic panels, and the support structure includes:

[0004] A support rod, hinged to the photovoltaic module, is used to support the module on an external placement surface. The support rod is configured to rotate relative to the photovoltaic module in a first direction.

[0005] The first support component is installed on the photovoltaic module.

[0006] The second support member is mounted on the support rod; and

[0007] The limiting member is movably connected to the second support member. The limiting member includes multiple abutting parts, which are arranged along the first direction. The abutting parts are used to abut the first support member, so that the angle between the support rod and the photovoltaic module is at a preset value.

[0008] The photovoltaic device has multiple support states, and each support state corresponds to a multiple abutment parts. In different support states, the included angle is at different preset values. In a support state, the abutment part corresponding to the support state abuts against the first support member along the first direction, so that the included angle is at the corresponding preset value.

[0009] The photovoltaic device is configured to switch between multiple support states by adjusting the relative positions of the limiting member and the second support member.

[0010] The beneficial effects of the photovoltaic device provided in this application are:

[0011] This application prevents the support rod from rotating relative to the photovoltaic module in the first direction by having the abutting part abut against the first support member in the first direction, thus ensuring that the angle between the support rod and the photovoltaic module is stably at a preset value. Furthermore, this application movably connects a limiting member to the second support member, and by adjusting the relative position of the limiting member and the second support member, the photovoltaic device can switch between multiple support states, thereby adjusting the angle between the support rod and the photovoltaic module. This allows the photovoltaic device to be adjusted by the user so that the direction in which the photovoltaic panel faces corresponds to the direction of external light, which is beneficial for improving the power generation efficiency of the photovoltaic device.

[0026] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods have been omitted so as not to obscure the description of this application with unnecessary detail.

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] It should be understood that the terms "comprising" and "having," and any variations thereof, used in this application and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0029] This application provides a photovoltaic device, which is a device for generating electricity using solar energy. The photovoltaic device has a stored state and a supported state. Please refer to... Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of a photovoltaic device in its stowed state, provided in some embodiments of this application.Figure 2 yes Figure 1 A three-dimensional structural diagram of the photovoltaic device in the embodiment under supported conditions.

[0030] The photovoltaic device 10 includes a photovoltaic module 11 and a support 12. The photovoltaic module 11 includes a photovoltaic panel 100 for generating solar power. The support 12 is hinged to the photovoltaic module 11 and is used to support it on an external placement surface. The external placement surface is, for example, but not limited to, the ground, a roof, etc. The support 12 is configured to rotate relative to the photovoltaic module 11 along a first direction X, so that by adjusting the angle between the support 12 and the photovoltaic module 11, the tilt angle of the photovoltaic module 11 on the external placement surface can be controlled to meet the usage requirements in various environments.

[0031] The photovoltaic module 11 includes a light-facing surface and a back-facing surface facing away from each other, and the support 12 is disposed on the side facing the back-facing surface. In the supported state, the support 12 can form a certain angle with the photovoltaic module 11 to support it on the external placement surface, so as to facilitate the photovoltaic module 11 to generate solar energy. In the stored state, the support 12 and the photovoltaic module 11 are folded together. The photovoltaic device 10 can switch between the supported state and the stored state by rotating the support 12 along the first direction X.

[0032] Understandably, the photovoltaic device 10 is typically used for solar power generation in its supported state and for storage, carrying, and transportation purposes in its stowed state, but the embodiments of this application do not limit this. For example, the photovoltaic device 10 can also generate solar power in its stowed state, in which case the photovoltaic panel 100 can be placed flat on the external placement surface.

[0033] In some embodiments, the photovoltaic module 11 may include a first portion 111 and a second portion 112, both of which include at least one photovoltaic panel 100. For example Figure 2 As shown, the first part 111 and the second part 112 each include a photovoltaic panel 100. The first part 111 and the second part 112 are foldably hinged together. In the stowed state, the first part 111 and the second part 112 can be folded for easy storage. In the supported state, the first part 111 and the second part 112 can be unfolded, for example, the angle between the first part 111 and the second part 112 can be about 180 degrees, in order to maximize the reception of sunlight. In the stowed state, the first part 111 and the second part 112 are folded together, and the backlighting surface of the first part 111 can be opposite to the backlighting surface of the second part 112.

[0034] In this configuration, at least one of the first part 111 and the second part 112 is provided with a support 12. For example, in the supported state, the photovoltaic device 10 can use the support 12 to support one of the first part 111 and the second part 112, while the other part is stably placed through the connection between the first part 111 and the second part 112. Alternatively, in the supported state, the photovoltaic device 10 can use at least two supports 12 to support the first part 111 and the second part 112 respectively, with the at least two supports 12 distributed on the side of the backlight facing the first part 111 and the side of the backlight facing the second part 112.

[0035] The photovoltaic device 10 can switch between a supported state and a stored state by rotating the support 12 relative to the photovoltaic module 11 and by rotating the first part 111 relative to the second part 112. Optionally, the rotation axis of the support 12 relative to the photovoltaic module 11 and the rotation axis of the first part 111 relative to the second part 112 can be two perpendicular axes. For example, the first part 111 and the second part 112 can rotate relative to each other about a vertical axis, and the support 12 and the photovoltaic module 11 can rotate relative to each other about a horizontal axis.

[0036] In other embodiments, the photovoltaic module 11 may also be a non-foldable structure. For example, the photovoltaic module 11 may only include the first part 111 and not the second part 112, and is not limited to the above embodiments. Of course, the photovoltaic module 11 may also include other parts besides the first part 111 and the second part 112, for example, it may consist of three foldable parts. The following description mainly uses the photovoltaic module 11 including the first part 111 and the second part 112 as an example.

[0037] It should be understood that the terminology used in this specification and appended claims is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise. Similarly, the terms “first” and “second” in the description of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include one or more of the stated features. Furthermore, the term “multiple” in the description of this application means two or more, unless otherwise explicitly specified.

[0038] Please refer to the following: Figures 1 to 3 , Figure 3 This is a partially exploded structural diagram of a photovoltaic device provided in some embodiments of this application. For ease of understanding, Figure 3The right half shown is the assembly structure, and the left half is the partially disassembled structure.

[0039] The first part 111 and the second part 112 can be connected by a hinge 113, allowing the first part 111 and the second part 112 to rotate relative to each other. The specific structure of the hinge 113 is not limited, for example, Figure 3 The hinge-type structure is shown. There is at least one hinge 113, which is located at the junction of the first part 111 and the second part 112.

[0040] In some embodiments, the photovoltaic module 11 includes at least two magnetic attractors 114, which are distributed on the first portion 111 and the second portion 112, and are magnetically attracted when the first portion 111 and the second portion 112 are folded. Optionally, at least one magnetic attractor 114 is provided at each corner of the first portion 111 and the second portion 112. In the folded state, when the first portion 111 and the second portion 112 are folded, the at least two magnetic attractors 114 at their corners will magnetically attract each other, so that the first portion 111 and the second portion 112 will be attracted together and will not easily separate.

[0041] Understandably, the two magnetically attracted components 114 can both be magnets, or one can be a magnet and the other a metal that can be attracted by a magnet. The specific placement of each magnetic component 114 can be set as needed, for example, but not limited to, at the corners of the first part 111 and the second part 112. In other embodiments, the first part 111 and the second part 112 can also achieve the anti-loosening function in other ways when in the stored state. For example, the corresponding positions of the first part 111 and the second part 112 can be provided with buckles, which can be used to fasten the first part 111 and the second part 112 when folded to prevent them from loosening.

[0042] In some embodiments, the photovoltaic module 11 may include a handle 115, which is fixed to the photovoltaic panel 100. The photovoltaic device 10 can be carried by lifting and handling the handle 115. The handle 115 can be connected to a component fixed to the photovoltaic panel 100 to achieve relative fixation with the photovoltaic panel 100. In other embodiments, the handle 115 may also be directly connected to the photovoltaic panel 100.

[0043] The handle 115 may be arc-shaped to facilitate gripping by the user. The surface of the handle 115 may at least partially have textures, protrusions, and / or grooves to improve grip. In other embodiments, the handle 115 may also be designed in other shapes, such as a ring. Optionally, the handle 115 is located on the first part 111. In the folded state, the first part 111 folds with the second part 112, and the bracket 12 folds with the photovoltaic module 11. At this time, the user can conveniently move the photovoltaic device 10 by gripping the handle 115.

[0044] The number of handles 115 can be... Figure 2 As shown, a handle 115 can be provided on the long side of the first part 111, so that the photovoltaic device 10 can be placed horizontally when being held, thereby reducing the risk of the photovoltaic device 10 hitting the ground. In other embodiments, there can be multiple handles 115. For example, both the long and short sides of the first part 111 can be provided with a handle 115, so that the user can choose one of the handles 115 to hold as needed.

[0045] Optionally, the handle 115 is entirely located on the first part 111. In the folded state, the first part 111 and the second part 112 are magnetically attracted and tightly folded together by at least two magnetic elements 114, so that the handle 115 can be used to hold the first part 111 and the second part 112. In other embodiments, both the first part 111 and the second part 112 may be provided with handles 115. In the folded state, the handles 115 on the first part 111 and the handles 115 on the second part 112 may overlap, so that the user can hold both handles 115 at the same time.

[0046] In some embodiments, the photovoltaic module 11 further includes a frame 200. The frame 200 is annular and surrounds the photovoltaic panel 100. In other words, the photovoltaic panel 100 is disposed within the frame 200. The specific shape of the frame 200 may correspond to that of the photovoltaic panel 100, for example, but not limited to, the photovoltaic panel 100 being rectangular and the frame 200 also being rectangular. The frame 200 may be connected to each side of the photovoltaic panel 100 to provide protection and support for the photovoltaic panel 100. Optionally, a handle 115 is provided on the frame 200. Both the first part 111 and the second part 112 include the photovoltaic panel 100 and the frame 200, and the frame 200 of the first part 111 and the frame 200 of the second part 112 are hinged together.

[0047] To prevent deformation of the photovoltaic panels, epoxy boards are usually attached to the back of the panels. However, this significantly increases the weight and thickness of the equipment, making it difficult to move. Furthermore, the edges of the panels are prone to localized deformation after prolonged exposure to high temperatures, which reduces the lifespan of the equipment.

[0048] In this embodiment, a ring-shaped frame 200 is used to surround the photovoltaic panel 100. This prevents the edges of the photovoltaic panel 100 from deforming due to prolonged exposure to high temperatures, while also not interfering with the power generation of the photovoltaic panel 100. The frame 200 can be at least partially a hollow metal component. For example, the frame 200 can include an aluminum extrusion, i.e., a component manufactured using an aluminum extrusion molding process, so that the frame 200 has the characteristics of being lightweight, high-strength, and easy to manufacture.

[0049] In some embodiments, the thickness of the frame 200 is greater than the thickness of the photovoltaic panel 100. Along the thickness direction of the photovoltaic panel 100, both ends of the frame 200 protrude from the photovoltaic panel 100 to form clearance zones 201 on opposite sides of the photovoltaic panel 100. In other words, on opposite sides of the photovoltaic panel 100, the frame 200 protrudes from the photovoltaic panel 100, and the clearance zones 201 are formed by the portion of the frame 200 protruding from the photovoltaic panel 100 along the thickness direction of the photovoltaic panel 100. Therefore, in scenarios where the photovoltaic module 11 comes into contact with external objects, the frame 200 can protect the photovoltaic panel 100. For example, when the front or back of the photovoltaic module 11 contacts a wall, due to the presence of the clearance zones 201, the photovoltaic module 11 can contact the wall through the frame 200, thereby preventing the surface of the photovoltaic panel 100 from being impacted.

[0050] The frame 200 may include protective strips 210 and corner protectors 220. Multiple protective strips 210 are distributed along each side of the photovoltaic panel 100 and are fitted around it. Corner protectors 220 are located at the intersection of the ends of two protective strips 210 and cover the corners of the photovoltaic panel 100. When the protective strips 210 and corner protectors 220 are locked together, they form a complete protective frame, i.e., the frame 200, to protect the photovoltaic panel 100 within it. The protective strips 210 may be hollow metal parts, such as extruded aluminum. The corner protectors 220 may be soft plastic parts to reduce the impact on the corners of the photovoltaic panel 100 when the photovoltaic module 11 collides with external objects. Of course, the corner protectors 220 may also be metal parts or rigid plastic. In other embodiments, the frame 200 may be designed with other structures, not limited to including protective strips 210 and corner protectors 220. For example, the frame 200 may consist of two mating half-frame components.

[0051] Optionally, the frame 200 has a hollow structure, and the internal space of the frame 200 is used for arranging wires. The wires electrically connected to the photovoltaic panel 100 can be arranged in the internal space of the frame 200. A junction box 230 can be provided on the outer surface of the frame 200. The junction box 230 can be located at, but is not limited to, a corner of the frame 200. Several wires inside the frame 200 can be gathered in the junction box 230 and connected to external electronic equipment through the junction box 230.

[0052] In this embodiment, the guard strips 210 and corner protectors 220 of the frame 200 can both be hollow structures, and the internal space of the guard strips 210 and corner protectors 220 can be used for wiring. Optionally, a junction box 230 can be disposed on the outer surface of one corner protector 220, and the wires can be arranged in each guard strip 210 and other corner protectors 220, and converge at the corner protector 220 where the junction box 230 is located, and enter the junction box 230 through the through hole on the corner protector 220. Of course, the wiring arrangement method of this embodiment is not limited to this.

[0053] The first part 111 and the second part 112 of the photovoltaic module 11 may both include a frame 200, and wires are arranged in both frames 200. A junction box 230 may be provided on the frame 200 of the first part 111. The wires of the first part 111 and the second part 112 can be gathered in the junction box 230, so that the photovoltaic device 10 can realize the electrical connection between each photovoltaic panel 100 and external electronic equipment through the junction box 230.

[0054] A cable protection box 240 may be provided at the junction of the frame 200 of the first part 111 and the frame 200 of the second part 112. The cable protection box 240 includes two foldable parts, one part of which is fixed to the frame 200 of the first part 111, and the other part is fixed to the frame 200 of the second part 112. The wires of the second part 112 can be gathered into the cable protection box 240, and then extend into the frame 200 of the first part 111 through the cable protection box 240. The cable protection box 240 can rotate with the rotation of the first part 111 and the second part 112, and covers the wires inside to prevent the wires from being exposed.

[0055] Optionally, the bracket 12 is disposed on the frame 200 and hinged to the frame 200. It is understood that the components disposed on the photovoltaic module 11 described herein, such as the bracket 12, handle 115, hinge 113, etc., can all be disposed on the frame 200 as needed; the following description mainly uses this as an example. However, it should be noted that the embodiments of this application do not limit these components to necessarily being disposed on the frame 200. For example, in some embodiments, these parts can be directly connected to the photovoltaic panel 100, or connected to other components on the photovoltaic panel 100.

[0056] The bracket 12 includes a support rod 300. The support rod 300 is hinged to the photovoltaic module 11 and is used to support it on the external placement surface. The support rod 300 is configured to rotate relative to the photovoltaic module 11 along a first direction X.

[0057] In some embodiments, one end of the support rod 300 may be provided with a flexible element 310. The other end of the support rod 300 is hinged to the photovoltaic module 11. In the supported state, the flexible element 310 can be used to abut against the external placement surface to improve support stability. The frame 200 may be provided with a storage portion 250 corresponding to the flexible element 310. In the stored state, the flexible element 310 abuts against the storage portion 250, and the support rod 300 is at least partially housed in the clearance area 201.

[0058] The storage portion 250 can have a toothed structure, and the toothed structure can be formed in various ways. For example, the storage portion 250 can include multiple parallel strip-shaped grooves to form an uneven toothed structure. Alternatively, the storage portion 250 can include multiple spaced protrusions to form an uneven toothed structure. The flexible member 310 is made of a flexible material that can be deformed by compression, such as soft rubber. When the photovoltaic device 10 switches from the supported state to the stored state, the support rod 300 rotates relative to the photovoltaic module 11 until the flexible member 310 contacts the storage portion 250. At this time, the flexible member 310 can increase the friction between itself and the storage portion 250 by compressing the storage portion 250, so that the support rod 300 can be stably folded with the photovoltaic module 11.

[0059] The support rod 300 is located on the side of the photovoltaic panel 100 facing away from the light. One end of the support rod is hinged to the frame 200, and the other end, in the retracted state, forms a limiting fit with the storage portion 250 of the frame 200 through a flexible member 310. Thus, in the retracted state, the support rod 300 can be accommodated within the clearance area 201 formed by the frame 200 on the back surface of the photovoltaic panel 100 without contacting the photovoltaic panel 100. In the retracted state, the flexible member 310 forms an interference fit with the storage portion 250 and the support rod 300. One end of the support rod 300 is fixed in the retracted state by the friction between the flexible member 310 and the storage portion 250, thereby preventing the support rod 300 from impacting the surface of the photovoltaic panel 100 during retraction.

[0060] It should be noted that preventing a certain phenomenon mentioned in this article does not mean completely eliminating it, but rather reducing the likelihood of it occurring.

[0061] Please see Figures 3 to 5 , Figure 4 yes Figure 3 An exploded view of the stent in the embodiment. Figure 5 yes Figure 4 The diagram shows a further exploded structural diagram of the support structure from another perspective.

[0062] The photovoltaic device 10 includes a first support member 260, which is disposed on the photovoltaic module 11. A bracket 12 can be hinged to the first support member 260, and thus hinged to the photovoltaic module 11 via the first support member 260. This will be used as an example in the following description. In other embodiments, the bracket 12 can also be hinged to the photovoltaic module 11 via other parts, or directly hinged to the photovoltaic module 11.

[0063] The first support member 260 can be disposed on the frame 200, for example, but not limited to, being fixed to the frame 200 by screws. The flexible member 310 can be disposed at the end of the support rod 300 away from the first support member 260.

[0064] In some embodiments, the bracket 12 may include a pivot 320. The pivot 320 is rotatably connected to the first support member 260. The support rod 300 is connected to the pivot 320 and hinged to the first support member 260 via the pivot 320 to achieve a hinge connection with the photovoltaic module 11. In other embodiments, the support rod 300 may also achieve a hinge connection with the photovoltaic module 11 in other ways. For example, the support rod 300 may include a protruding shaft that can replace the pivot 320 and be hinged to the first support member 260. The following description mainly uses the bracket 12 including the pivot 320 as an example.

[0065] There are several ways to connect the support rod 300 to the rotating shaft 320. For example, the bracket 23 may include a support rod sleeve 330, which has mounting holes corresponding to the support rod 300 and the rotating shaft 320. Both the support rod 300 and the rotating shaft 320 are inserted into the mounting holes of the support rod sleeve 330, so that the support rod 300 can be connected to the rotating shaft 320 through the support rod sleeve 330, and then hinged to the photovoltaic module 11 through the rotating shaft 320 and the first support member 260. In other embodiments, the support rod 300 can also be connected to the rotating shaft 320 in other ways, for example, the rotating shaft 320 can be inserted into the support rod 300.

[0066] Optionally, the support rod 300 includes two parallel long rods and a short rod connecting the two long rods. The short rod is connected to the same end of the two long rods, and the other ends of the two long rods are hinged to the photovoltaic module 11. In other words, the support rod 300 is a U-shaped rod. The connection between the short rod and the long rod can be chamfered. The flexible member 310 can be a hollow columnar structure and is sleeved on one end of the support rod 300, specifically on the short rod of the support rod 300. In other embodiments, the support rod 300 can also be other shapes, such as columnar. The following description mainly uses a U-shaped support rod 300 as an example.

[0067] In this design, the longer end of the support rod 300, away from the shorter end, is inserted into the support rod sleeve 330. A pivot 320 is positioned between two support rod sleeves 330, each connected to one of the two longer rods, with both ends of the pivot 320 inserted into the two support rod sleeves 330 respectively. The connection between the support rod sleeve 330 and the support rod 300 and pivot 320 can be, but is not limited to, reinforcement using adhesive or screws. The support rod sleeve 330 can be made of wear-resistant and UV-resistant plastic. The pivot 320 can be a polygonal metal rod, for example... Figure 5 The hexagonal metal rod shown has a polygonal mounting hole on the support sleeve 330 for inserting the rotating shaft 320, which prevents the rotating shaft 320 from rotating relative to the support sleeve 330 and helps to improve the assembly stability of the bracket 12.

[0068] Optionally, the bracket 12 further includes a retaining ring 340 sleeved on the rotating shaft 320. An annular groove may be formed on the surface of the rotating shaft 320, and the retaining ring 340 is secured within this groove to stably fit on the rotating shaft 320. The bracket 12 may include two retaining rings 340, located on opposite sides of the first support member 260 along the axial direction of the rotating shaft 320, and both abutting against the first support member 260 to prevent the rotating shaft 320 from moving relative to the first support member 260 along its axial direction. The shape of the retaining ring 340 can be set as needed, for example, as an E-shaped ring.

[0069] Optionally, the support 12 also includes, for example, Figure 3 The damping pad 350 is shown. A rotating shaft 320 can pass through the first support member 260 and the second support member 400. The second support member 400 is mounted on the support rod 300 via the rotating shaft 320. The damping pad 350 can be sleeved on the rotating shaft 320 and positioned between the first support member 260 and the second support member 400. The damping pad 350 can abut against at least one of the first support member 260 and the second support member 400 to increase the rotational damping of the bracket 12 and prevent the bracket 12 from rotating too fast and impacting the photovoltaic panel 100.

[0070] In some embodiments, the bracket 12 may include two damping pads 350. Along the axial direction of the rotating shaft 320, the two damping pads 350 may be respectively disposed on opposite sides of the first support member 260, and the opposite sides of each damping pad 350 abut against the first support member 260 and the second support member 400.

[0071] In other words, a damping pad 350 can be provided between the two opposing surfaces of the first support member 260 and the second support member 400, abutting against the first support member 260 and the second support member 400, so that the first support member 260 and the second support member 400 are pre-loaded with friction damping. Along the axial direction of the shaft 320, the opposite sides of the first support member 260 are respectively arranged opposite to the opposite sides of the second support member 400. Therefore, in this embodiment, by providing a damping pad 350 on each of the opposite sides of the first support member 260, the aforementioned friction damping can be further improved. In other embodiments, the bracket 12 may also include only one damping pad 350, which is disposed on the opposite side of the first support member 260 and the second support member 400.

[0072] In other embodiments, a plurality of stacked damping pads 350 may be provided between the two opposing surfaces of the first support member 260 and the second support member 400, wherein some of the damping pads 350 abut against the first support member 260 and some of the damping pads 350 abut against the second support member 400.

[0073] In this embodiment, the bracket 12 can rotate relative to the photovoltaic module 11 to form different angles with the photovoltaic module 11. In the supported state, the bracket 12 can be supported on the outer placement surface and abut against the photovoltaic module 11, so that the photovoltaic module 11, the outer placement surface and the bracket 12 form a triangular support structure, thereby allowing the photovoltaic module 11 to be placed tilted on the outer placement surface.

[0074] The photovoltaic device 10 also includes a limiting structure for stably maintaining the angle between the support bracket 12 and the photovoltaic module 11 at a preset value in the supported state, so that the photovoltaic device 10 can be stably placed on the external placement surface in the supported state. There can be multiple preset values, and the photovoltaic device 10 can have multiple different support states, each corresponding to one of the preset values. The photovoltaic device 10 can switch to different support states by adjusting the limiting structure; in different support states, the angle between the support bracket 12 and the photovoltaic module 11 is different. Please refer to [link / reference]. Figure 6 , Figure 6 This is a schematic diagram of the planar structure of three photovoltaic devices in different support states provided in some embodiments of this application;

[0075] Multiple photovoltaic devices 10 in different support states have different angles between their supports 12 and photovoltaic modules 11. Therefore, when multiple photovoltaic devices 10 in different support states are placed on the same external placement surface, the angles between each photovoltaic module 11 and the external placement surface are also different. In this application embodiment, the angle between the photovoltaic module 11 and the external placement surface is mainly used as a parameter to characterize the degree of tilt of the photovoltaic module 11.

[0076] Taking the external placement surface as a plane as an example, such as Figure 6 As shown, the three photovoltaic devices 10 arranged from left to right have photovoltaic modules 11 with angles A, B, and C relative to the external placement surface, respectively. It can be seen that from left to right, the angle between the photovoltaic module 11 and the support 12 increases sequentially, while angles A, B, and C decrease sequentially, indicating that the tilt of the photovoltaic module 11 increases sequentially.

[0077] Angles A, B, and C represent the angles formed when the angle between the photovoltaic module 11 and the external placement surface is at three different preset values. For example, when the angle between the photovoltaic module 11 and the support 12 is at the first preset value, the angle between the photovoltaic module 11 and the external placement surface is angle A; when the angle between the photovoltaic module 11 and the support 12 is at the second preset value, the angle between the photovoltaic module 11 and the external placement surface is angle B; and when the angle between the photovoltaic module 11 and the support 12 is at the third preset value, the angle between the photovoltaic module 11 and the external placement surface is angle C.

[0078] The sizes of angles A, B, and C are related to various preset values, and can be specifically limited as needed, for example, but not limited to, angle A being 60 degrees, angle B being 50 degrees, and angle C being 40 degrees. The photovoltaic device 10 provided in this application embodiment can adjust the limiting structure as needed to adjust the included angle between the photovoltaic module 11 and the support 12 to the required preset value, so that the photovoltaic device 10 switches to the corresponding support state, so that the photovoltaic module 11 can form a preset tilt angle with the external placement surface.

[0079] Of course, the number of angles that the photovoltaic module 11 can form with the external placement surface when supported is not limited to 3; it can also be 3 or less. In addition, in practical applications, the photovoltaic module 11 can also be placed flat on the external placement surface, in which case the angle formed between the photovoltaic module 11 and the external placement surface is 0 degrees.

[0080] The limiting structure will be described below. For ease of explanation, the angle between the photovoltaic module 11 and the bracket 12 will be referred to as the support angle, and the angle between the photovoltaic module 11 and the external placement surface will be referred to as the tilt angle.

[0081] Please refer to the above text. Figures 7 to 9 , Figure 7 yes Figure 3 The diagram shows a partially enlarged view of the photovoltaic module. Figure 8 yes Figure 4 The diagram shows a partially enlarged structural schematic of the support. Figure 9 yes Figure 5 The diagram shows a partially enlarged structural schematic of the support structure. It should be noted that... Figure 3 The photovoltaic device 10 shown is only partially in a disassembled state. Figure 7 The following is shownFigure 3 A local structure that is in the assembly state.

[0082] In some embodiments, the bracket 12 includes a first support member 260, a second support member 400, and a limiting member 500. The first support member 260 is disposed on the photovoltaic module 11, the second support member 400 is disposed on the support rod 300, and the limiting member 500 is movably connected to the second support member 400.

[0083] The support rod 300 is configured to rotate relative to the photovoltaic module 11 along the first direction X.

[0084] The limiting member 500 includes multiple abutment portions 520, which are arranged along the first direction X. The abutment portions 520 are used to abut the first support member 260, so that the angle between the support rod 300 and the photovoltaic module 11 is at a preset value. The angle between the support rod 300 and the photovoltaic module 11 can be regarded as the angle between the bracket 12 and the photovoltaic module 11, and is also referred to as the support angle below.

[0085] The photovoltaic device 10 has multiple support states. Each support state corresponds one-to-one with a plurality of abutment portions 520. The support angle is at different preset values ​​in different support states; correspondingly, the photovoltaic device 10 can have different tilt angles in different support states. Optionally, Figure 6 The angles A, B, and C shown are the tilt angles of the photovoltaic device 10 under three different support conditions.

[0086] In the supported state, the abutment portion 520 corresponding to this supported state abuts against the first support member 260 along the first direction X, so that the included angle of support is at the corresponding preset value. The photovoltaic device 10 is configured to switch between multiple supported states by adjusting the relative position of the limiting member 500 and the second support member 400.

[0087] For example, in the first supported state, the limiting member 500 is in the first position. At this time, the first abutting part 520 of the limiting member 500 abuts against the first supporting member 260, so that the supporting angle is at a first preset value. In the second supported state, the limiting member 500 is in a second position different from the first position. At this time, the second abutting part 520 of the limiting member 500 abuts against the first supporting member 260, so that the supporting angle is at a second preset value different from the first preset value.

[0088] Therefore, the user can adjust the relative position of the limiting member 500 and the second support member 400 according to the change of the external light angle, so as to change the abutting part 520 of the limiting member 500 that abuts against the first support member 260, thereby changing the support angle and thus the tilt angle. Understandably, the support angle of the photovoltaic device 10 can be switched between multiple preset values ​​in the above manner, and the number of preset values ​​is two or more.

[0089] This application embodiment also provides a limiting structure to prevent the limiting member 500 from shifting under the action of the first support member 260 in the supported state, and to facilitate the movement of the limiting member 500 relative to the second support member 400 under user adjustment so that the photovoltaic device 10 can switch between multiple supported states.

[0090] In some embodiments, the second support member 400 is provided with a plurality of first limiting holes 401, the first limiting holes 401 penetrating the wall of the second support member 400 along the second direction Y, and the plurality of first limiting holes 401 are arranged along the third direction Z. Multiple support states correspond one-to-one with the plurality of first limiting holes 401.

[0091] The limiting member 500 includes a first limiting part 510. In the supported state, the first limiting part 510 is inserted into the first limiting hole 401 corresponding to the supported state along the second direction Y, and abuts against the hole wall of the first limiting hole 401 along the third direction Z.

[0092] The photovoltaic device 10 also has an adjustment state, in which the limiting member 500 is movable relative to the second support member 400 to change the relative position of the limiting member 500 and the second support member 400. Thus, the photovoltaic device 10 can switch from a support state to an adjustment state to move the limiting member 500 to the desired position, and then switch from the adjustment state to the next support state.

[0093] The photovoltaic device 10 is configured to switch from a support state to an adjustment state by moving the first limiting part 510 out of the first limiting hole 401 along the second direction Y; and to switch from an adjustment state to a support state by moving the limiting member 500 along the third direction Z to a position where the first limiting part 510 is opposite to a first limiting hole 401 and inserting the first limiting part 510 into the first limiting hole 401 along the second direction Y.

[0094] Wherein, the first direction X is the rotation direction of the support rod 300 relative to the photovoltaic module 11. The second direction Y is the depth direction of the first limiting hole 401, which can also be regarded as the axial direction of the first limiting part 510. The third direction Z is the arrangement direction of the plurality of first limiting holes 401. The first direction X, the second direction Y, and the third direction Z each contain two opposite directions. For example, the support rod 300 can rotate clockwise or counterclockwise relative to the photovoltaic module 11 along the first direction X.

[0095] Taking the limiting member 500 including three abutment portions 520 as an example, correspondingly, the second support member 400 is provided with three first limiting holes 401 arranged sequentially along the third direction Z, and the photovoltaic device 10 has at least three support states. In the first support state, the first abutment portion 520 abuts against the first support member 260 to prevent the support rod 300 from rotating relative to the photovoltaic module 11 along the first direction X, so that the support angle is at a first preset value, thereby making the tilt angle the first preset angle, for example, . Figure 4 Angle A is shown. At this time, the first limiting part 510 is inserted into the first limiting hole 401, and forms a limiting engagement with the first limiting hole 401 in the first direction X and the third direction Z, to prevent the limiting member 500 from moving relative to the second support member 400.

[0096] At this time, the first support member 260 applies a force in the first direction X to the limiting member 500. Since the hole wall of the first limiting hole 401 abuts against the first limiting part 510 in the first direction X, the limiting member 500 will not move under the force of the first support member 260. Therefore, the abutting part 520 can stably prevent the support rod 300 from rotating in the first direction X.

[0097] When the photovoltaic device 10 needs to adjust the support angle to a second preset value, the photovoltaic device 10 can switch from the first support state to the adjustment state by moving the first limiting part 510 out of the first limiting hole 401 along the second direction Y. In the adjustment state, the first limiting part 510 is outside the first limiting hole 401, and the limiting member 500 can move relative to the second support member 400.

[0098] Furthermore, the photovoltaic device 10 can move the limiting member 500 along the third direction Z to a position where the first limiting part 510 is opposite to the second first limiting hole 401, and insert the first limiting part 510 into the second first limiting hole 401 along the second direction Y. After the limiting member 500 makes the above movement, the first abutment part 520 will separate from the first support member 260, causing the first support member 260 to disengage from the limiting of the first abutment part 520. When the limiting member 500 moves to the above position, the second abutment part 520 corresponding to the second first limiting hole 401 will abut against the first support member 260, so that the support angle is at the second preset value, and the photovoltaic device 10 switches to the second support state.

[0099] Similarly, the photovoltaic device 10 can also adjust the support angle to other preset values ​​in a similar manner. Multiple support states, multiple preset values, multiple abutment portions 520, and multiple first limiting holes 401 correspond one-to-one. Optionally, the first direction X, the second direction Y, and the third direction Z are all parallel to a preset plane perpendicular to the surface of the photovoltaic panel 100. The preset plane can be understood as a hypothetical plane perpendicular to the surface of the photovoltaic panel 100. Specifically, the second direction Y is perpendicular to the third direction Z. The following explanation will primarily use this as an example.

[0100] In other embodiments, the plurality of first limiting holes 401 may also be arranged in other directions. For example, the plurality of first limiting holes 401 may be arranged in another direction, which forms an acute or obtuse angle with the second direction Y. In the supported state, the first limiting part 510 is inserted into the first limiting hole 401 corresponding to the supported state along the second direction Y. In other embodiments, the first direction X, the second direction Y, and the third direction Z are not limited to the above design. For example, the first direction X may form an acute angle with the second direction Y or the third direction Z.

[0101] Multiple first limiting holes 401 can be arranged and connected sequentially along the third direction Z to reduce the distance between two adjacent first limiting holes 401. The diameter of the connecting portion of two adjacent first limiting holes 401 is smaller than the outer diameter of the first limiting part 510 to prevent the first limiting part 510 from being inserted into the connecting portion in the adjusted state. In other embodiments, the multiple first limiting holes 401 can also be arranged at intervals along the third direction Z.

[0102] Understandably, the change in tilt angle of the photovoltaic device 10 under different support states is affected by the spacing of the multiple first limiting holes 401. In this embodiment, by connecting the multiple first limiting holes 401 sequentially along the third direction Z, the distance between two adjacent first limiting holes 401 can be minimized to the greatest extent, thereby reducing the minimum change in the tilt angle of the photovoltaic device 10 during adjustment, which is beneficial to expanding the selectable tilt angle range of the photovoltaic device 10.

[0103] The specific shape of the abutment 520 can be designed as needed, as long as it can fulfill the above-mentioned functions. Optionally, the limiting member 500 includes triangular limiting teeth 530, and different tooth surfaces of the limiting teeth 530 serve as different abutment portions 520. Figure 8 As shown, the limiting tooth 530 is a triangular protrusion, and each limiting tooth 530 has two tooth surfaces arranged along the arc direction. In two different support states, the limiting member 500 can abut against the first support member 260 through the two different tooth surfaces.

[0104] In some embodiments, the limiting member 500 includes a plurality of limiting teeth 530, which are arranged along a first direction X and connected sequentially. Thus, the limiting member 500 may have two or more abutment portions 520. For example... Figure 8 As shown, the two tooth surfaces of one limiting tooth 530 and one tooth surface of another adjacent limiting tooth 530 can serve as three adjacent abutment portions 520, corresponding to three different support states. Similarly, there can be more than three abutment portions 520. In other embodiments, the limiting member 500 may also include only one limiting tooth 530, and have one or two abutment portions 520.

[0105] The triangular tip of the limiting tooth 530 can be an edge, an arc surface, or a plane. In other embodiments, the abutment portion 520 can also be other structures, such as multiple protrusions arranged along the first direction X, and is not limited to this embodiment.

[0106] In some embodiments, the second support member 400 has a scale portion 410 on its outer wall where the first limiting hole 401 is provided. The scale portion 410 includes a plurality of scale marks 411 arranged along the third direction Z, and the plurality of scale marks 411 correspond one-to-one with the plurality of first limiting holes 401 arranged along the third direction Z. The limiting member 500 has a viewing window 501 in the area opposite to the scale portion 410. It can be understood that the plurality of scale marks 411 correspond one-to-one with the plurality of support states.

[0107] The scale mark 411 may, but is not limited to, be a value corresponding to the tilt angle of the supported state. When the photovoltaic device 10 switches from the adjustment state to a certain supported state, the scale mark 411 corresponding to that supported state will be displayed in the viewing window 501, so that the user can determine the value of the tilt angle of the photovoltaic device 10 at this time based on the scale mark 411 observed from the viewing window 501. The scale part 410 may be a component fixed to the second support member 400, and the scale mark 411 may be provided on the component. The scale part 410 may also be a part of the second support member 400, and the scale mark 411 may be provided on the second support member 400. The shape and content of the scale mark 411 can be designed as needed and are not limited here.

[0108] The limiting member 500 may include a limiting body 540, a stop portion 520 and a first limiting portion 510, both of which are disposed on the limiting body 540. Their relative positions can be set as needed. For example, the first limiting portion 510 may protrude from the bottom surface of the limiting body 540, and the stop portion 520 may be disposed on the side surface of the limiting body 540. The shape of the limiting body 540 can be designed as needed.

[0109] In some embodiments, the limiting body 540 may include a main body 541 and two secondary bodies 542 protruding from the main body 541. The main body 541 may cover a portion of the second support member 400 and cover each of the first limiting holes 401. The two secondary bodies 542 may be arranged opposite each other and distributed on opposite sides of the second support member 400 along a fourth direction to limit the direction of movement of the limiting member 500 relative to the second support member 400. The fourth direction is a straight line direction perpendicular to the second direction Y and the third direction Z. The main body 541 and the two secondary bodies 542 may cooperate to surround a portion of the second support member 400. Both secondary bodies 542 may abut against the second support member 400.

[0110] Optionally, the limiting member 500 further includes an operating part 550, which protrudes from the limiting body 540, and the number of operating parts 550 is at least one. For example, the limiting member 500 may include two operating parts 550, which protrude along a fourth direction on opposite sides of the limiting body 540. The user can control the movement of the limiting member 500 by lifting the operating part 550.

[0111] In some embodiments, the bracket 12 further includes an elastic element 600 disposed in the second support member 400. Please refer to... Figures 7 to 9 See Figure 10 and Figure 11 , Figure 10 This is a cross-sectional structural diagram of some of the supports provided in the embodiments of this application in a supported state. Figure 11 yes Figure 10 The diagram shows a cross-sectional view of part of the support structure in the adjusted state.

[0112] The elastic member 600 is connected to the limiting member 500, and one end of the elastic member 600 abuts against the inner wall of the second support member 400, which has a first limiting hole 401. The elastic member 600 is used to apply an elastic restoring force along the second direction Y to the limiting member 500.

[0113] In the supported state, the first limiting part 510 is inserted into the first limiting hole 401. At this time, the elastic member 600 can apply an elastic force toward the second support member 400 to the limiting member 500 to prevent the limiting member 500 from moving along the second direction Y and disengaging from the second support member 400.

[0114] During the process of switching the photovoltaic device 10 from the support state to the adjustment state, the first limiting part 510 will gradually move out of the first limiting hole 401 along the second direction Y. The elastic member 600 will undergo elastic deformation along the second direction Y under the action of the limiting member 500, and provide the limiting member 500 with the elastic force to reset along the second direction Y.

[0115] When the limiting member 500 moves along the third direction Z in the adjusted state to the position where the first limiting part 510 is opposite to a first limiting hole 401, the limiting member 500 can move along the second direction Y under the action of the elastic member 600, so that the first limiting part 510 is inserted into the first limiting hole 401 along the second direction Y.

[0116] In this embodiment, an elastic member 600 is provided in the second support member 400, connected to the limiting member 500 and abutting against the inner wall of the second support member 400 having a first limiting hole 401. This allows the limiting member 500 to move along the second direction Y and to fit tightly with the second support member 400 in a supported state. In other embodiments, the elastic member 600 may not be provided in the second support member 400.

[0117] In this embodiment, the portion of the elastic element 600 connected to the limiting element 500 can be the end of the elastic element 600 away from the inner wall of the second support member 400 where the first limiting hole 401 is located. In other words, one end of the elastic element 600 abuts against the aforementioned inner wall of the second support member 400, and the other end is connected to the limiting element 500. In other embodiments, the elastic element 600 can also be connected to the limiting element 500 through another portion, such as the middle portion of the elastic element 600. The following description uses the example of the elastic element 600 being connected to the limiting element 500 through its other end.

[0118] In some embodiments, the second support member 400 is provided with a second limiting hole 402. The second limiting hole 402 may be a strip-shaped hole extending along a third direction Z. The second limiting hole 402 penetrates the wall of the second support member 400 along a second direction Y. The limiting member 500 also includes a second limiting portion 560, which is inserted into the second limiting hole 402 and slides in cooperation with the wall of the second limiting hole 402.

[0119] The second limiting part 560 is used to cooperate with the second limiting hole 402 to restrict the movement trajectory of the limiting member 500 in the adjustment state. In both the support and adjustment states, the second limiting part 560 is inserted into the second limiting hole 402. In the adjustment state, due to the abutment of the second limiting part 560 by the wall of the second limiting hole 402, the movement of the limiting member 500 relative to the second support member 400 is restricted. It can only move relative to the second support member 400 in the third direction Z through the sliding engagement between the second limiting part 560 and the wall of the second limiting hole 402, thereby preventing misalignment of the limiting member 500 relative to the second support member 400.

[0120] In some embodiments, the limiting member 500 may include one second limiting portion 560 and at least two first limiting portions 510. The number of first limiting portions 510 is plurality of, and they are symmetrically arranged along the second limiting portion 560. Each first limiting portion 510 corresponds to a set of first limiting holes 401, and each set of first limiting holes 401 includes a plurality of first limiting holes 401 arranged along a third direction Z. In other embodiments, the first limiting portions 510 and the second limiting portions 560 may also be arranged in other ways, and the number of both the first limiting portions 510 and the second limiting portions 560 may be at least one.

[0121] The other end of the elastic member 600 can be connected to the second limiting portion 560. In some embodiments, the connection between the elastic member 600 and the limiting member 500 is indirect. The bracket 12 may include a fixing member 700, which includes a connecting portion 710 and a receiving portion 720. The connecting portion 710 is connected to one end of the second limiting portion 560 located within the second support member 400. The receiving portion 720 is disposed on the connecting portion 710 and protrudes from the outer peripheral surface of the connecting portion 710. One end of the elastic member 600 abuts against the inner wall of the second support member 400 where the first limiting hole 401 is provided, and the other end abuts against the receiving portion 720.

[0122] In this embodiment, the fastener 700 can be a screw. The connecting portion 710 is the screw body, fixed to one end of the second limiting portion 560. The receiving portion 720 is the screw head, protruding from the screw body, and receiving the elastic member 600. In other embodiments, the fastener 700 can also be other devices, such as a rivet. In other embodiments, the elastic member 600 can also be directly connected to the limiting member 500, thus eliminating the need for the fastener 700.

[0123] The elastic element 600 can be a compression spring. The elastic element 600 can surround the portion of the second limiting portion 560 located within the second support member 400. In other embodiments, the elastic element 600 can also be other devices that provide the aforementioned elastic force, and its arrangement is not limited to surrounding the second limiting portion 560. For example, the elastic element 600 can be arranged side-by-side with the second limiting portion 560. The number of elastic elements 600 is at least one. The connection between the elastic element 600 and the limiting member 500 can be, but is not limited to, abutment; for example, the elastic element 600 can be welded to the limiting member 500.

[0124] The elastic element 600 can also be connected to the second limiting portion 560 directly or indirectly. In other embodiments, the elastic element 600 can also be connected to other parts of the limiting element 500, such as the first limiting portion 510, wherein a plurality of first limiting holes 401 are sequentially connected along the third direction Z, and the outer diameter of the elastic element 600 is smaller than the diameter of the connection between two adjacent first limiting holes 401. The limiting element 500 provided in this application embodiment can be equipped with or without the second limiting portion 560 as needed.

[0125] In some embodiments, the second support member 400 may have a limiting groove 403 on the inner wall of the first limiting hole 401, and one end of the elastic member 600 is accommodated in the limiting groove 403 to prevent misalignment. The limiting groove 403 can be adapted to the elastic member 600. Specifically, the inner diameter of the limiting groove 403 can be equal to or slightly larger than the outer diameter of one end of the elastic member 600.

[0126] The limiting groove 403 can be formed by a protrusion on the inner wall of the second support member 400. This protrusion can be an integral structure or a separate structure. In other embodiments, the limiting groove 403 can also be formed by a recess in the inner wall of the second support member 400. The elastic member 600 can surround the second limiting part 560 and the connecting part 710, with one end abutting against the groove wall of the limiting groove 403 and the other end abutting against the receiving part 720.

[0127] In some embodiments, the first limiting hole 401 and the second limiting hole 402 may both be disposed on the same wall of the second support member 400, and correspondingly, the first limiting portion 510 and the second limiting portion 560 may be disposed on the same side of the limiting body 540. In other embodiments, the first limiting hole 401 and the second limiting hole 402 may also be disposed on different walls of the second support member 400. Please refer to [link / reference]. Figure 12 and Figure 13 , Figure 12 This is a cross-sectional structural diagram of a portion of the support structure provided in some other embodiments of this application in a supported state. Figure 13 yes Figure 12 The diagram shows a cross-sectional view of part of the support structure in the adjusted state.

[0128] In some embodiments, the first limiting hole 401 and the second limiting hole 402 are respectively provided on two oppositely disposed walls of the second support member 400. The first limiting part 510 and the second limiting part 560 are respectively provided on opposite sides of the limiting member 500, and the first limiting part 510 is inserted into the first limiting hole 401 in the supporting state and disengaged from the first limiting hole 401 in the adjusting state, while the second limiting part 560 is inserted into the second limiting hole 402 in both the supporting and adjusting states.

[0129] In the supported state, the elastic member 600 applies a spring force along the second direction Y to the second limiting portion 560 in a direction away from the first limiting portion 510. Since both the first limiting portion 510 and the second limiting portion 560 are part of the limiting member 500, under the action of this spring force, the first limiting portion 510 can be stably inserted into the first limiting hole 401. During the process of the photovoltaic device 10 switching from the supported state to the adjustment state, the second limiting portion 560 will move in the direction opposite to the first limiting portion 510 under the action of external force, so that the first limiting portion 510 gradually moves out of the first limiting hole 401 along the second direction Y, while the elastic member 600 is compressed.

[0130] It should be noted that in other embodiments, the limiting member 500 can be movably connected to the second support member 400 in other ways, and the photovoltaic device 10 can also be provided with other limiting structures to achieve similar effects, and is not limited to the shaft hole limiting structure described above.

[0131] For example, the second support member 400 may be provided with a slide rail, and the limiting member 500 may be slidably disposed in the slide rail to achieve a movable connection with the second support member 400. The slide rail may be provided with multiple slots, each corresponding to a different support state. In the support state, the limiting member 500 may be engaged in one slot, so that the stop part 520 corresponding to the support state abuts against the first support member 260. The user may manipulate the limiting member 500 to slide, so that the limiting member 500 disengages from one slot and engages in another slot, thereby changing the position of the limiting member 500 relative to the second support member 400. This allows the limiting member 500 to abut against the first support member 260 through another stop part 520, thus switching the photovoltaic device 10 to another support state.

If the specific posture changes, the directional indication will also change accordingly.
