Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a photovoltaic component and a photovoltaic box. Background Art

[0002] In conventional photovoltaic boxes, usually, the photovoltaic panels are of a standard rectangular structure. After the photovoltaic components are unfolded, it is impossible to seal between two adjacent photovoltaic panels. A "V"-shaped gap can be formed between the two adjacent photovoltaic panels. On the one hand, this affects the overall aesthetics. On the other hand, on rainy days, rainwater will flow into the gap. Since the photovoltaic panels are tilted, rainwater will flow along the gap to the back of the photovoltaic panels under gravity, which may easily cause damage to the circuit components on the back of the photovoltaic panels. In order to overcome this problem, the circuit components on the back of the photovoltaic panels need to be sealed, which not only increases the cost, but also increases the overall quality, which is not conducive to users' carrying. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] A first aspect of the utility model provides a photovoltaic assembly.

[0005] A second aspect of the utility model provides a photovoltaic box.

[0006] The photovoltaic assembly provided in the first aspect of the utility model includes: a hinge structure, including a first rotating member and a second rotating member; two photovoltaic panels, respectively arranged on the first rotating member and the second rotating member; the first rotating member and the second rotating member can rotate relative to each other, and drive the two photovoltaic panels to rotate to a folded state or an unfolded state, when the two photovoltaic panels are rotated to the unfolded state, the ends of the first surfaces of the two photovoltaic panels that are close to each other abut against each other, wherein the surface of the photovoltaic panel away from the hinge structure is the first surface.

[0007] The utility model arranges the two photovoltaic panels on the photovoltaic module so that, in the unfolded state, the upper surfaces of the two adjacent photovoltaic panels can abut against each other, so that the "V"-shaped gap mentioned in the background technology does not exist, so that rainwater will not flow into the back of the photovoltaic module through the gap, but can only slide along the upper surface of the photovoltaic panel. In this way, there is no need to waterproof the circuit components on the back of the photovoltaic module, which saves costs, simplifies the structure, reduces the overall quality, and is convenient for users to carry with them.

[0008] In the above technical solution, optionally, the photovoltaic panel includes: a panel body; and frames provided on both sides of the panel body; when the two photovoltaic panels are rotated to an unfolded state, the two photovoltaic panels abut against each other through two adjacent frames.

[0009] In this technical solution, by setting frames at both ends of the plate body, the two photovoltaic panels are abutted against each other through the two adjacent frames, that is, the ends of the upper surfaces of the two frames that are close to each other are abutted against each other. This design method can protect the plate body on the one hand, and on the other hand, the structure of the frame is easier to design into different shapes, which can better achieve the sealing between the two photovoltaic panels, so there is no need to set other seals.

[0052] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. 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.

[0053] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0055] The utility model arranges the two photovoltaic panels 124 on the photovoltaic module 12 so that, in the unfolded state, the upper surfaces of the two adjacent photovoltaic panels 124 can abut against each other, so that the "V"-shaped gap mentioned in the background technology does not exist, so that rainwater will not flow into the back of the photovoltaic module 12 through the gap, and can only slide down the upper surface of the photovoltaic panel 124. In this way, there is no need to waterproof the circuit component 15 on the back of the photovoltaic module 12, which saves costs, simplifies the structure, reduces the overall quality, and is convenient for users to carry with them.

[0056] In the above embodiment, optionally, Figure 2 As shown, the photovoltaic panel 124 includes a panel body 1244 and a frame 1246 , and the frame 1246 is disposed on both sides of the panel body 1244 ; when the two photovoltaic panels 124 are rotated to the unfolded state, the two photovoltaic panels 124 abut against each other through two adjacent frames 1246 .

This design method can protect the plate body 1244 on the one hand, and on the other hand, the structure of the frame 1246 is easier to design into different shapes, which can better achieve the sealing between the two photovoltaic panels 124, so there is no need to set other seals.

[0058] In the above embodiment, optionally, along the rotation axis direction of the photovoltaic panel 124 , the end faces at both ends of the frame 1246 are trapezoidal.

[0059] In this embodiment, the cross-section of the frame 1246 is set to be a trapezoid. This is because the two trapezoidal frames 1246 can achieve sealing, fill the "V-shaped" gap in the background technology, and provide waterproof protection for the circuit component 15 on the back of the photovoltaic component 12.

[0060] In the above embodiment, optionally, Figure 2 and Figure 7 As shown, the photovoltaic panel 124 includes a panel body 1244 and an elastic seal 1248 , and the elastic seal 1248 is disposed on both sides of the panel body 1244 ; when the two photovoltaic panels 124 are rotated to the unfolded state, the two photovoltaic panels 124 abut against each other through two adjacent elastic seals 1248 .

[0061] In this embodiment, elastic seals 1248 are provided at both ends of the plate body 1244. Compared with the frame 1246, the elastic seals 1248 have good elasticity, and can better achieve the sealing between the two photovoltaic modules 12. Optionally, when the two photovoltaic panels 124 are unfolded, the elastic seals 1248 on the two photovoltaic panels 124 are in a compressed state, which can further improve the sealing performance.

[0062] In the above embodiment, optionally, the photovoltaic panel 124 includes a panel body 1244 and a frame 1246 arranged at both ends of the panel body 1244, and two adjacent photovoltaic panels 124 are abutted by the frame 1246. The photovoltaic assembly 12 also includes a roller 126, and the roller 126 is arranged on both ends of the frame 1246 along the first direction, or is arranged on both ends of the photovoltaic panel 124 along the first direction, and is arranged close to the frame 1246; wherein the first direction is the direction of the rotation axis of the photovoltaic panel 124.

[0063] In this embodiment, rollers 126 are provided at both ends of the frame 1246 or at both ends of the photovoltaic panel 124 , so that the movement of the photovoltaic assembly 12 can be facilitated. In addition, the rollers 126 are provided at both ends, so that the rollers 126 do not affect the folding of the photovoltaic assembly 12 .

[0064] A second aspect of the present invention provides a photovoltaic box 1, comprising: a plurality of photovoltaic components 12 according to any one of the embodiments of the first aspect of the present invention.

[0065] Since the photovoltaic box 1 provided by the utility model includes the photovoltaic assembly 12 of any one of the embodiments of the first aspect of the utility model, it has all the beneficial effects of the photovoltaic assembly 12 of any one of the embodiments of the first aspect of the utility model.

[0066] In the above embodiment, optionally, two adjacent photovoltaic assemblies 12 share a photovoltaic panel 124 .

[0067] In the above embodiment, optionally, Figure 1 and Figure 6 As shown, the plurality of photovoltaic components 12 can be deployed along a first curve 10 , and the first curve 10 includes at least one trough 102 and at least one peak 104 .

[0068] In this embodiment, the plurality of photovoltaic modules 12 are arranged in a state of crests 104 and troughs 102, which is more conducive to receiving light from the sun 2 and can increase power generation compared to being arranged along the same horizontal plane. Optionally, the troughs 102 and crests 104 are arranged alternately.

[0069] In the above embodiment, optionally, Figure 1 , Figure 2 and Figure 6 As shown, the plurality of photovoltaic components 12 include a first photovoltaic component 127 located at the end along the unfolding direction of the photovoltaic components 12 , and the photovoltaic box 1 also includes a handle groove 13 provided on the first photovoltaic component 127 .

[0073] In the above embodiment, optionally, the photovoltaic panel 124 includes a panel 12442 and a back panel 12444.

[0074] In this embodiment, by providing the circuit assembly 15 and the power supply port 16, power supply can be provided at any time. In addition, since the multiple photovoltaic assemblies 12 of the utility model can be sealed, there is no need to seal the circuit assembly 15, which saves costs, simplifies the structure, reduces the overall quality, and facilitates the user to carry it with him. It is understandable that the circuit assembly 15 of the utility model is not provided with a sealing structure.

[0076] In this embodiment, by providing the first power supply port 162 and the second power supply port 164 , different power supply functions can be implemented according to different requirements, and the application scope is wider.

[0077] In the above embodiment, optionally, Figure 3 and Figure 4 As shown, the photovoltaic box 1 also includes universal wheels 17 , which are arranged below the box body 14 .

[0078] In this embodiment, universal wheels 17 are provided below the box 14, so that the box 14 can be moved better and is more convenient for users to carry with them.

[0081] In the above embodiment, optionally, Figure 3 As shown, the photovoltaic box 1 also includes a telescopic pull rod 192 which is telescopically arranged on the box body 14 .

[0082] In this embodiment, the photovoltaic box 1 further includes a telescopic pull rod 192, which is telescopically arranged on the box body 14, so that the user can better pull the photovoltaic box 1 and carry it with him more conveniently.

[0083] In the above embodiment, optionally, Figure 3As shown, the photovoltaic box 1 further includes a support rod 194 connected between the box body 14 and the second photovoltaic assembly 128 .

[0084] In this embodiment, the photovoltaic box 1 further includes a support rod 194 connected between the box body 14 and the second photovoltaic assembly 128, so that the photovoltaic assembly 12 can be fixed when it is unfolded to prevent the photovoltaic assembly 12 from sliding sideways in strong winds.

[0085] The applicant will now describe the photovoltaic box 1 of the present invention from another perspective.

[0086] As a new energy source, solar energy has the advantages of abundant reserves, wide distribution, clean and environmental protection compared with traditional energy sources. Therefore, its research and application are increasingly valued by today's society. In order to provide continuous power supply, people have established distributed photovoltaic power stations, but the photovoltaic arrays of traditional distributed photovoltaic power stations are fixed and have a long installation period. With the popularity of personal travel, people have an increasing demand for mobile photovoltaic panels. However, the existing portable photovoltaic panels are all miniaturized and cannot meet people's growing electricity demand. In order to solve this problem, we have designed a portable photovoltaic array power generation box.

[0087] First, the applicant introduces two different designs of photovoltaic panels 124 .

[0088] like Figure 8 and Fig.10 As shown, Scheme A is a W-type photovoltaic array, in which any photovoltaic panel 124 forms an angle of α with the horizontal plane. According to the longitude and latitude, solar altitude and azimuth of each country, the photovoltaic array inclination angle α is greater than or equal to 15° and less than or equal to 60°. It should be noted that the photovoltaic array mentioned in this article is composed of multiple photovoltaic modules 12 connected in sequence, which will not be described below.

[0089] like Fig. 9 and Fig.11 As shown, solution B is a planar photovoltaic array, wherein any photovoltaic panel 124 is arranged parallel to the horizontal plane.

[0090] like Figure 8 As shown, the angle between the photovoltaic panel 124 and the horizontal plane is α, and the angle between the light emitted by the sun 2 and the normal line of the photovoltaic panel 124 on the left side in the vertical direction is θ 1 , the incident angle between the light emitted by the sun 2 and the photovoltaic panel 124 on the right is θ 2 ,like Fig. 9 As shown, in the B scheme, the incident angle θ between the light emitted by the sun 2 and the photovoltaic panel 124 is 3 .

[0091] When the sun 2 is between 6 and 9 in the morning, the incident angle θ1 of the light emitted by the sun 2 and the photovoltaic panel 124 on the left in Plan A is the smallest, close to 0°. For a photovoltaic panel 124, the different incident angles of the sun 2 on it will result in different amounts of solar normal radiation received per unit area. The smaller the incident angle, the more solar normal radiation received. Therefore, Plan A has the smallest incident angle θ1, and at this time, Plan A receives more solar normal radiation than Plan B.

[0092] like Fig.10 and Fig.11 As shown, when the sun 2 is between 11 and 12 noon, the incident angle θ3 of the light emitted by the sun 2 and the photovoltaic panel 124 in scheme B is the smallest, close to 0°. At this time, the incident angles θ1 and θ2 of the light emitted by the sun 2 in scheme A and the photovoltaic panels 124 on the left and the photovoltaic panels 124 on the right are both greater than θ3. Therefore, the incident angle θ3 of scheme B is the smallest. At this time, scheme B receives more normal solar radiation than scheme A.

[0093] When the sun 2 is at 3 to 4 p.m., the incident angle θ2 between the light emitted by the sun 2 and the photovoltaic panel 124 on the right side of solution A is the smallest, close to 0°. At this time, solution A receives more normal solar radiation than solution B.

[0094] According to the position of the sun 2 during the day, the optimal normal solar radiation amount can be received by Plan A for the longest time, so the W-type photovoltaic array of Plan A is better than the planar photovoltaic array in Plan B.

[0095] Based on this, the utility model provides a photovoltaic box 1, which can also be called a W-shaped foldable storage photovoltaic box 1, which adopts the design of a hinge structure 122 and a roller group. Each adjacent photovoltaic panel 124 is connected by a hinge structure 122, and a roller 126 is installed at the bottom of the photovoltaic panel 124. In addition, a handle groove 13 is installed at the front end of the first photovoltaic panel 124 of each photovoltaic array, which is convenient for users to unfold and store the entire photovoltaic array. When the first photovoltaic panel 124 is pulled open, the roller 126 at the bottom of the photovoltaic panel 124 will move forward horizontally, and at the same time, the adjacent photovoltaic panels 124 will be driven to move forward horizontally through the hinge structure 122, thereby unfolding the entire photovoltaic array in sequence.

[0096] The utility model provides a photovoltaic box 1, which comprises a photovoltaic array and a box assembly. The photovoltaic array comprises a plurality of photovoltaic assemblies 12.

[0097] The photovoltaic assembly 12 is composed of a handle groove 13, multiple sets of rollers 126, a photovoltaic panel 124, a frame 1246, and a hinge structure 122, wherein the hinge structure 122 connects multiple photovoltaic panels 124 to each other to form a photovoltaic array, and the multiple sets of rollers 126 can ensure that the photovoltaic panel 124 is unfolded in the horizontal direction when the handle groove 13 is pulled horizontally.

[0098] The box assembly consists of a box 14, a support rod 194, a universal wheel set, a low-voltage output port, a high-voltage output port, a longitudinal handle 182, a telescopic pull rod 192, and a transverse handle 184. The universal wheel set is composed of multiple sets of universal wheels 17 assembled at the same level to ensure that the box 14 can be opened smoothly. The longitudinal handle 182 and the transverse handle 184 can provide pulling methods in different directions. The support rod 194 provides fixation when the photovoltaic array is unfolded to prevent the photovoltaic array from sliding sideways in strong winds. The low-voltage output port and the high-voltage output port can provide two voltage output modes, with a low-voltage output range of 60V and a high-voltage output range of 90V to 500V, which is convenient for users to choose the appropriate power supply method in different scenarios. When the photovoltaic array is folded and stored in the box 14, the telescopic pull rod 192 can directly pull the box 14 to move with it.

[0099] like Figure 6 As shown, the light emitted by the sun 2 reaches the photovoltaic array as parallel light, and there is an angle with the photovoltaic panels 124 of the W-shaped photovoltaic panel 124 array. When the incident angle of the light emitted by the sun 2 is smaller, the more normal solar radiation is received, and the higher the power generation of the photovoltaic array is.

[0100] like Figure 5 As shown, the inclination angle of the photovoltaic array is mainly determined by the two frames 1246 of the photovoltaic panel 124 being fixed together by the hinge structure 122 below. The frame 1246 is trapezoidal in shape, which can support the photovoltaic panel 124 to a specific angle, thereby realizing the W-shape of the photovoltaic array.

[0101] The photovoltaic box 1 provided by the utility model is small in size and can be carried around. Compared with the conventional photovoltaic box 1, it is more compact and occupies a smaller area when unfolded. It adopts a W-shaped folding method, so that the photovoltaic panel 124 receives light for a longer time and has a higher power generation efficiency. It is easy to use and does not require complicated installation. The photovoltaic panel 124 can be used as soon as it is unfolded.
