Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic module. Background Art

[0002] Conventional photovoltaic modules often require a bracket to be designed on the back of each folded photovoltaic panel, that is, the number of photovoltaic panels is the same as the number of brackets. In this way, when the photovoltaic panels are stored, the brackets need to repeat the storage action the same number of times as the number of folds of the photovoltaic panels. In this way, when the number of folds of the photovoltaic panels is large, the folding process of the photovoltaic panels is complicated and the workload is high. Summary of the invention

[0003] The present invention aims to at least solve the problem of complicated folding process of supporting brackets of photovoltaic panels existing in the related art.

[0004] To this end, the first aspect of the present invention provides a photovoltaic assembly, comprising: a plurality of photovoltaic panels, the plurality of photovoltaic panels are arranged along a first direction, any two adjacent photovoltaic panels are connected by a hinge axis and can rotate relative to each other around the hinge axis, so that the photovoltaic assembly can be converted between a folded state and an unfolded state, and the two adjacent photovoltaic panels include a first photovoltaic panel and a second photovoltaic panel; a support bracket, comprising: a rotating connection member, including a first rotating end and a second rotating end that can rotate relative to each other, and the direction of the rotation axis of the first rotating end and the second rotating end is consistent with the axis direction of the hinge axis; two support segments, one end of one support segment is connected to the first rotating end, and the other end is connected to the first photovoltaic panel, and one end of the other support segment is connected to the second rotating end, and the other end is connected to the second photovoltaic panel; wherein, when the first photovoltaic panel and the second photovoltaic panel are folded around the hinge axis, the two support segments rotate synchronously and are respectively placed on the back of the first photovoltaic panel and the second photovoltaic panel to form a storage state.

[0005] The photovoltaic assembly provided by the present invention has a support bracket connecting two adjacent photovoltaic assemblies. When two adjacent photovoltaic panels are folded, the support bracket can be stored. That is to say, when two adjacent photovoltaic panels are folded, the support bracket only needs to be folded once, and the number of times the support bracket is folded is less than the number of folds of the photovoltaic panels, thereby greatly reducing the workload of folding the support bracket.

[0006] In the above technical solution, optionally, the support section is rotatably connected to the back of the photovoltaic panel via a rotating shaft, the extension direction of the rotating shaft is the same as the first direction, and the support section can rotate around the rotating shaft so that the supporting bracket can be in a supporting state and support the photovoltaic component; wherein, when the supporting bracket is in a supporting state, the supporting section forms a preset angle with the photovoltaic panel.

[0007] In this technical solution, the support section can rotate relative to the photovoltaic panel, thereby forming a certain angle with the photovoltaic panel, thereby supporting the photovoltaic panel.

[0008] In the above technical solution, optionally, the photovoltaic assembly also includes a fixing plate, one end of which is connected to the back of the photovoltaic panel, and the other end of which is connected to the supporting section, for fixing the supporting section so that the supporting bracket is in a supporting state.

[0009] In this technical solution, the fixing plate fixes and supports the supporting bracket, ensuring that the supporting bracket remains in a supporting state, thereby improving the supporting stability of the supporting bracket.

[0010] In the above technical solution, optionally, a connecting section is provided at one end of the fixing plate connected to the supporting section, a surface of the connecting section coincides with a surface of the supporting section, and the supporting section and the connecting section are connected by a bayonet pin.

[0011] In this technical solution, when the support bracket is supporting, the support section is inclined, so an inclined connecting section is provided at the end of the fixed section, which is more conducive to the assembly of the support section and the fixed plate. The connecting section and the support section are connected by a bayonet pin, thereby realizing quick release.

[0012] In the above technical solution, optionally, along the first direction, the length of the photovoltaic panel is L1, the supporting bracket includes two suspended sections connected to the photovoltaic panel and a contact section connected between the two suspended sections, and when the supporting bracket is in a supporting state, the suspended section is suspended and the contact section is in contact with the fixed structure; wherein, the length of the contact section is L2, and the ratio of L2 to L1 is greater than or equal to 0.4.

[0013] In this technical solution, the ratio of the length of the contact segment to the length of the photovoltaic panel is limited to ensure sufficient supporting area, thereby ensuring stable supporting performance. Compared with conventional one-shaped supports, the supporting length is longer and the stability is better.

[0014] In the above technical solution, optionally, the photovoltaic assembly also includes a bracket fixing member, which is arranged on the back of the photovoltaic panel. The bracket fixing member is provided with an axial hole, and the rotating shaft is rotatably connected in the axial hole so that the support section can rotate relative to the bracket fixing member.

[0015] In this technical solution, the support bracket is not directly connected to the photovoltaic panel, but connected to the bracket fixing member, so as to avoid damage to the photovoltaic panel when installing the support bracket. The rotation of the support segment is achieved by matching the shaft of the support segment with the shaft hole on the bracket fixing member.

[0016] In the above technical solution, optionally, the photovoltaic assembly also includes a reinforcing plate, which is arranged on the back of the photovoltaic panel and is used to reinforce the photovoltaic panel.

[0017] In this technical solution, the reinforcing plate is used to reinforce the photovoltaic panel, thereby improving the impact resistance of the photovoltaic panel.

[0018] In the above technical solution, optionally, along the first direction, the plurality of photovoltaic panels include third photovoltaic panels located at both ends, and a handle structure is provided on the third photovoltaic panel.

[0019] In this technical solution, handle structures are provided on the photovoltaic panels at both ends to facilitate the unfolding and folding of the photovoltaic panels.

[0020] In the above technical solution, optionally, the number of supporting brackets is less than the number of photovoltaic panels.

[0021] In this technical solution, the number of supporting brackets is less than the number of photovoltaic panels, achieving the same supporting effect, making the structure simpler.

[0022] In the above technical solution, optionally, the number of photovoltaic panels is an even number, and the number of supporting brackets is half the number of photovoltaic panels.

[0023] In this technical solution, the number of support brackets is half the number of photovoltaic panels, thereby reducing the number of support brackets and simplifying the structure compared to the conventional method of providing a straight-line bracket on the back of each photovoltaic panel.

[0024] In the above technical solution, optionally, the shape of the supporting bracket is U-shaped or inverted trapezoidal.

[0025] In the above technical solution, optionally, the rotating connection member includes a flexible connection member or a hinge. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the first aspect of the present invention provides a photovoltaic assembly 1, comprising a plurality of photovoltaic panels 11 and a support bracket 12 arranged along a first direction, the first direction can be the length direction of the photovoltaic panel 11, that is, the unfolding direction of the photovoltaic assembly 1, any two adjacent photovoltaic panels 11 are connected by a hinge shaft 17 and can rotate relative to each other around the hinge shaft 17, so that the photovoltaic assembly 1 can be converted between a folded state and an unfolded state; the support bracket 12 comprises a rotating connector 122 and two support segments 124, the rotating connector 122 comprises a first rotating end 1222 and a second rotating end 1224 that can rotate relative to each other, the direction of the rotation axis of the first rotating end 1222 and the second rotating end 1224 is the same as the hinge axis The axis direction of the connecting shaft 17 is consistent; one end of a support segment 124 is connected to the first rotating end 1222, and the other end is connected to the first photovoltaic panel 112, for example, connected to the back of the first photovoltaic panel 112 away from the light-receiving surface; one end of the other support segment 124 is connected to the second rotating end 1224, and the other end is connected to the second photovoltaic panel 114, for example, connected to the back of the second photovoltaic panel 114 away from the light-receiving surface; the light-receiving surface is the surface that receives sunlight. When the first photovoltaic panel 112 and the second photovoltaic panel 114 are folded around the hinge shaft 17, the two support segments 124 can rotate synchronously and are respectively placed on the backs of the first photovoltaic panel 112 and the second photovoltaic panel 114 to form a storage state. The storage state is as follows: Figure 4 shown.

[0031] The photovoltaic assembly 1 provided by the present invention has a support bracket 12 connecting two adjacent photovoltaic assemblies 1. When two adjacent photovoltaic panels 11 are folded, the two support sections 124 of the support bracket 12 can rotate synchronously for storage. That is to say, when two adjacent photovoltaic panels 11 are folded, the support bracket 12 only needs to be folded once, and the number of times the support bracket 12 is folded is less than the number of folds of the photovoltaic panels 11, thereby greatly reducing the workload of folding the support bracket 12.

[0032] Similarly, when two adjacent photovoltaic panels 11 are unfolded, the two support segments 124 can also rotate and unfold synchronously. Compared with the conventional solution of setting a support bracket on the back of each photovoltaic panel, the number of unfolding and folding of the support bracket 12 is greatly reduced, thereby improving work efficiency.

[0033] In addition, since the two support segments 124 of the present application are respectively connected to two adjacent photovoltaic panels 11, the photovoltaic strength of each photovoltaic panel 11 can also be guaranteed. That is, compared with the conventional support method, the support strength of the photovoltaic panel 11 is not lost, but the deployment and storage efficiency of the support bracket 12 is greatly improved.

[0034] In addition, when the support bracket 12 is in the storage state, the support bracket 12 automatically folds and stores along with the photovoltaic panel 11, and the middle half of the support bracket 12 is sandwiched between the adjacent photovoltaic panels 11, and the other half of the support bracket 12 can also be fixed along, without the need for additional Velcro fixation; that is, Figure 4 and Figure 5 As shown, the first support section 1244 is located between the two photovoltaic panels 11 and is fixed by the two photovoltaic panels 11 . Therefore, the second support section 1246 does not need to be provided with a fixing device such as Velcro.

[0035] In the above embodiment, optionally, Figure 2 As shown, the support segment 124 is rotatably connected to the back of the photovoltaic panel 11 via a rotating shaft 1242, and the extension direction of the rotating shaft 1242 is the same as the first direction. The support segment 124 can rotate around the rotating shaft 1242 so that the supporting bracket 12 can be in a supporting state and support the photovoltaic component 1; wherein, when the supporting bracket 12 is in a supporting state, the supporting segment 124 forms a preset angle with the photovoltaic panel 11.

[0036] In this embodiment, the support segment 124 is rotatably connected to the back of the photovoltaic panel 11, and the axial direction of the rotation of the support segment 124 is the same direction as the first direction. The support segment 124 can rotate relative to the photovoltaic panel 11, thereby being in a supporting state and supporting the photovoltaic component 1 or retracting the support segment 124 for storage.

[0037] When the supporting bracket 12 is in a supporting state, the supporting section 124 forms a preset angle with the photovoltaic panel 11. The larger the preset angle, the larger the inclination angle of the photovoltaic panel 11, and the smaller the preset angle, the smaller the inclination angle of the photovoltaic panel 11. The inclination angle refers to the angle between the photovoltaic panel 11 and the vertical direction.

[0038] Optionally, the preset angle is greater than or equal to 30 degrees and less than or equal to 120 degrees, for example, 60 degrees or 90 degrees.

[0039] In the above embodiment, optionally, the photovoltaic assembly 1 also includes a fixing plate 13, one end of which is connected to the back of the photovoltaic panel 11, and the other end of the fixing plate 13 is connected to the supporting segment 124, for fixing the supporting segment 124 so that the supporting bracket 12 is in a supporting state.

[0040] In this embodiment, the photovoltaic assembly 1 also includes a fixing plate 13, one end of the fixing plate 13 is connected to the back of the photovoltaic panel 11, and the other end of the fixing plate 13 is connected to the supporting section 124, so that when photovoltaic power generation is required, the supporting bracket 12 is maintained in a supporting state through the fixing plate 13, thereby realizing photovoltaic power generation.

[0041] It can be understood that when photovoltaic power generation is needed, the support segment 124 is fixed by the fixing plate 13, so that the support segment 124 forms a preset angle with the photovoltaic panel 11, thereby continuously generating electricity. When the fixing plate 13 is needed, the fixing plate 13 can be removed from the back of the photovoltaic panel 11 to store the support bracket 12.

[0042] Optionally, one end of the fixing plate 13 is rotatably connected to the back of the photovoltaic panel 11, so that the fixing plate 13 can rotate on the surface of the photovoltaic panel 11. When power generation is required, the fixing plate 13 supports the support bracket 12, so that the support bracket 12 is in a supporting state to achieve power generation. When storage is required, the fixing plate 13 is rotated and attached to the surface of the photovoltaic panel 11, and the support bracket 12 is rotated and stored.

[0043] Optionally, a receiving groove for receiving the fixing plate 13 can be provided on the back of the photovoltaic panel 11, so that when storing, the fixing plate 13 can be placed in the receiving groove and then locked by a locking member to improve the stability of the fixing plate 13. Of course, the fixing plate 13 can also be fixed by an interference fit between the fixing plate 13 and the receiving groove.

[0044] The storage of the photovoltaic assembly 1 of the present application is very convenient. It only requires rotating the fixing plate 13 to make the fixing plate 13 fit the surface of the photovoltaic panel 11, and then rotating the supporting bracket 12 to the surface of the photovoltaic panel 11, and finally folding the photovoltaic panel 11 to complete the storage of the photovoltaic panel 11 and the supporting bracket 12.

[0045] In the above embodiment, optionally, a connecting section 132 is provided at one end of the fixing plate 13 connected to the supporting section 124, a surface of the connecting section 132 coincides with the surface of the supporting section 124, and the supporting section 124 and the connecting section 132 are connected by a bayonet.

[0046] In this embodiment, when the supporting bracket 12 is supporting, the supporting section 124 is inclined, so an inclined connecting section 132 is set at the end of the fixed section, and one surface of the connecting section 132 coincides with the surface of the supporting section 124, which is more conducive to the assembly of the supporting section 124 and the fixing plate 13.

[0047] During the assembly process, threaded holes can be provided on the connecting section 132 and the supporting section 124, and then the connecting section 132 and the supporting section 124 can be connected by bolts, so that the connection strength between the connecting section 132 and the supporting section 124 is better. Of course, the supporting section 124 can also be directly placed on the connecting section 132, which makes it more convenient to store the support bracket 12.

[0048] Optionally, the inclined connecting section 132 is connected to the supporting section 124 via a bayonet pin, thereby achieving quick release.

[0049] In the above embodiment, optionally, Figure 5 and Figure 6 As shown, along the first direction, the length of the photovoltaic panel 11 is L1, and the supporting bracket 12 includes two suspended sections 126 connected to the photovoltaic panel 11 and a contact section 128 connected between the two suspended sections 126. When the supporting bracket 12 is in a supporting state, the suspended sections 126 are suspended, and the contact section 128 is in contact with the fixed structure 129; wherein, the length of the contact section 128 is L2, and the ratio of L2 to L1 is greater than or equal to 0.4.

[0050] In this embodiment, along the first direction, the length of the photovoltaic panel 11 is L1, and the supporting bracket 12 includes two suspended sections 126 connected to the photovoltaic panel 11 and a contact section 128 connected between the two suspended sections 126. When the supporting bracket 12 is in a supporting state, the suspended section 126 is suspended, and the contact section 128 is in contact with a fixed structure 129. The fixed structure 129 can be the ground or other structures that can fix the supporting bracket 12.

[0051] The length of the contact segment 128 is L2, and the ratio of L2 to L1 is greater than or equal to 0.4. By limiting the ratio of the length of the contact segment 128 to the length of the photovoltaic panel 11, sufficient support area is ensured, thereby ensuring stable support. Compared with conventional straight-line support members, the support length is longer and the stability is better. Optionally, the ratio of L2 to L1 is greater than or equal to 0.5.

[0052] In the above embodiment, optionally, Figure 1 and Figure 3 As shown, the photovoltaic assembly 1 also includes a bracket fixing member 14, which is arranged on the back of the photovoltaic panel 11. The bracket fixing member 14 is provided with an axial hole 1442, and the rotating shaft 1242 is rotatably connected in the axial hole 1442, so that the support section 124 can rotate relative to the bracket fixing member 14.

[0053] In this technical solution, the present application does not directly connect the support bracket 12 to the photovoltaic panel 11, but connects it to the bracket fixing member 14, so as to avoid damage to the photovoltaic panel 11 when installing the support bracket 12. The rotation of the support segment 124 is achieved by matching the rotating shaft 1242 of the support segment 124 with the shaft hole 1442 on the bracket fixing member 14.

[0054] In addition, the bracket fixing member 14 can be welded to the back of the photovoltaic panel 11, so that the connection strength is better. Of course, other connection methods such as bolts can also be selected.

[0055] In addition, when the rotating shaft 1242 rotates in the shaft hole 1442, a blocking member can be provided on the bracket fixing member 14 to limit the rotation angle of the support segment 124. For example, the maximum angle between the support segment 124 and the photovoltaic panel 11 can be set to 120°. This can avoid the angle between the support segment 124 and the photovoltaic panel 11 being too large, resulting in low support stability.

[0056] Of course, in some embodiments, a driving member can be provided to drive the support segment 124 to rotate, so as to precisely adjust the angle between the support segment 124 and the photovoltaic panel 11, thereby precisely controlling the inclination angle of the photovoltaic panel 11 to meet the requirements of various sunlight angles.

[0057] In the above embodiment, optionally, the photovoltaic assembly 1 further includes a reinforcing plate 15 , which is disposed on the back of the photovoltaic panel 11 and is used to reinforce the photovoltaic panel 11 .

[0058] In this technical solution, a reinforcing plate 15 is provided on the back of the photovoltaic panel 11, so that the photovoltaic panel 11 can be reinforced. The reinforcing plate 15 can be arranged along the first direction, or can be arranged perpendicular to the first direction, that is, can be arranged along the width or length of the photovoltaic panel 11. The number of reinforcing plates 15 on the back of each photovoltaic panel 11 is set according to actual conditions, for example, it can be 1 to 3.

[0059] Optionally, the support fixture 14 is installed on the reinforcing plate 15 , so that the photovoltaic panel 11 will not be damaged during the installation of the support fixture 14 .

[0060] In the above embodiment, optionally, Figure 4 and Figure 6 As shown, along the first direction, the plurality of photovoltaic panels 11 include third photovoltaic panels 116 located at both ends, and the third photovoltaic panels 116 are provided with handle structures 1162 .

[0061] In this technical solution, a handle structure 1162 is provided on the photovoltaic panels 11 at both ends, so as to facilitate the unfolding and folding of the photovoltaic panels 11. The handle structure 1162 can be a through hole provided on the third photovoltaic panel 116 and penetrating along the thickness direction of the third photovoltaic panel 116, or a handle, etc.

[0062] In the above embodiment, optionally, the number of the supporting brackets 12 is less than the number of the photovoltaic panels 11 .

[0063] In this technical solution, the number of supporting brackets 12 is less than the number of photovoltaic panels 11, and they have the same supporting effect, making the structure simpler.

[0064] In the above technical solution, optionally, the number of photovoltaic panels 11 is an even number, and the number of supporting brackets 12 is half of the number of photovoltaic panels 11 .

[0065] In this technical solution, the number of support brackets 12 is half the number of photovoltaic panels 11, that is, every two photovoltaic panels 11 are connected by one support bracket 12, so that in the process of recovering and unfolding the photovoltaic assembly 1, the unfolding and storage workload can be reduced by half. Compared with setting a straight bracket on the back of each photovoltaic panel 11, the number of support brackets 12 is reduced and the structure is simplified.

[0066] In the above technical solution, optionally, the shape of the support bracket 12 is U-shaped or inverted trapezoidal. Compared with a straight-line single bracket, the U-shaped bracket forms a four-point support when unfolded, and the structure is more stable and reliable. In the above technical solution, optionally, the rotating connection member 122 includes a flexible connection member or a hinge.

[0067] Another embodiment of the present application provides a photovoltaic assembly. Before describing the photovoltaic assembly of this embodiment, it is necessary to understand that when the photovoltaic panel is working, it is necessary to maintain a certain inclination angle in order to better receive sunlight radiation, so a back bracket needs to be installed. Portable photovoltaic panels need to be unfolded and stored frequently and used in outdoor exposure environments. The bracket body needs to have good rigidity and weather resistance, and the bracket connection part needs to have a certain flexibility or rotatability. The bracket design is as light and thin as possible, easy to store, and stable and non-deformed during long-term use. Photovoltaic panels work outdoors for a long time. In order to avoid collapse or deformation of the bending area of ​​multi-fold photovoltaic panels, it is often necessary to design a bracket on the back of each folded photovoltaic panel. When the user unfolds and stores, he needs to repeat the unfolding and storage actions the same number of times as the photovoltaic panel is folded. The operation process is cumbersome, and when the photovoltaic panel is longer, the unfolding operation is more difficult.

[0068] The present invention provides a U-shaped folding storage bracket, comprising a U-shaped bracket assembly and a U-shaped bracket fixing assembly, which together constitute a stable inverted trapezoidal structure; the U-shaped bracket assembly comprises: a U-shaped first bracket body (equivalent to a second support segment 1246), a U-shaped second bracket body (equivalent to the first support segment 1244), a flexible connector (equivalent to a rotating connector 122), a rotating shaft structural member (equivalent to the rotating shaft 1242), a fifth bolt 205 (fixing screw), and a third bolt 203 (fixing I-shaped screw) in the middle of a storage belt 202; the U-shaped bracket fixing assembly comprises: a bracket fixing structural member (equivalent to a bracket fixing member 14), a fourth bolt 204 (fixing screw) of the structural member, a storage belt 202, and a first bolt 201 (fixing I-shaped screw) at the bottom of the storage belt 202.

[0069] The flexible connection can be a soft rubber flexible connection or a hinge rigid connection.

[0070] 1. For the photovoltaic assembly of the present invention, for the multi-fold photovoltaic panel, the U-shaped bracket reduces the workload and difficulty of operation by half when unfolding and folding the U-shaped bracket, compared with the straight bracket, and is more convenient for users to operate; 2. Compared with the straight single bracket, the U-shaped bracket forms an inverted trapezoidal structure with four points of support when unfolded, and the structure is more stable and reliable; 3. When the U-shaped bracket is in the storage state, the bracket will automatically fold and store along with the photovoltaic panel, and the middle half of the bracket will be clamped in the middle of the photovoltaic panel. The other half of the bracket can also be fixed along with it without the need for additional Velcro fixation.
