Description

Technical Field

[0001] The utility model relates to the technical field of solar panels, and in particular to a solar panel assembly. Background Art

[0002] Currently, outdoor portable photovoltaic panels on the market usually adopt a folding design. The inclination adjustment of the photovoltaic panels usually adopts a mechanical structure, which cannot achieve stepless adjustment. In addition, the unfolding and storage processes are relatively cumbersome, and the overall weight is large, which is not conducive to carrying, thus limiting the power generation efficiency of the photovoltaic panels under different lighting conditions.

[0003] Therefore, how to provide a solar panel assembly that can be adjusted steplessly and is easy to carry has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model provides a solar panel assembly, which solves the problem in the related art that the portable solar panel cannot be adjusted steplessly and reduces the difficulty of unfolding and storing the solar panel assembly.

[0005] Therefore, the first object of the present invention is to provide a solar panel assembly.

[0006] In view of this, an embodiment of the first aspect of the utility model provides a solar panel assembly, comprising: a solar panel; a bracket, a first end of the bracket being rotatably connected to the solar panel, and a second end of the bracket being able to move relative to the solar panel to approach or move away from the solar panel; an elastic member, one end of the elastic member being connected to the solar panel, and the other end of the elastic member being connected to the second end of the bracket; wherein, when the bracket and the solar panel reach a preset angle, the elastic member is in a stretched state.

[0007] The solar panel assembly provided by the utility model includes a battery panel, a bracket and an elastic member, wherein the first end of the bracket is rotatably connected to the battery panel, and the second end of the bracket can move relative to the battery panel to get closer to or away from the battery. That is, the bracket is rotatably connected to the battery panel, and during the rotation process, the first end is relatively immobile with the battery panel, and the second end moves relative to the battery panel, so that the second end of the bracket and the battery panel change position. One end of the elastic member is connected to the battery panel, and the other end of the elastic member is connected to the second end of the bracket. That is, the two ends of the elastic member are respectively connected to the battery panel and the bracket, and when the bracket rotates relatively around the battery panel and the bracket and the battery panel reach a preset angle, the elastic member is in a stretched state, which indicates that the elastic member generates a pulling force on the battery panel, so that the bracket and the battery panel have a tendency to close, and because the battery panel and the bracket are both placed on the ground, the battery panel and the bracket form a friction force with the ground, and the friction force is equal in magnitude and opposite in direction to the force that generates the closing tendency, thereby forming a stable state for the bracket and the battery panel. At the same time, the preset angle can be an angle range, for example, the preset angle is less than 180° and greater than 0°. By setting the elastic member, the bracket and the solar panel can be adjusted steplessly at the preset angle, that is, the angle of the solar panel can be adjusted arbitrarily within the preset angle, without setting a gear in the rotating structure to fix the solar panel. In addition, since the elastic member does not need to set a gear, it is convenient for users to unfold and store the solar panel assembly, reducing the difficulty of unfolding and storing.

[0008] In addition, in some products, the hinge structure can also be set to stepless adjustment, such as laptop screens, but a damper needs to be additionally set in the hinge structure. The damper can support the weight of the laptop screen, but for solar panel components with large weight and volume, the support strength of the damper is relatively weak, and the use of damper support is prone to damage to the damper. Therefore, on solar panels, a hinge structure with gears is generally used, but this hinge structure with gears cannot achieve stepless adjustment and cannot arbitrarily adjust the inclination angle of the solar panel and the ground.

[0009] In some embodiments, optionally, the solar panel assembly further includes: a connecting member, one end of which is connected to the solar panel, and the other end of which is connected to the elastic member; the elastic member includes: a first section of the elastic member, one end of which is connected to the solar panel; a second section of the elastic member, one end of which is connected to the second end of the bracket, and the other end of which is connected to the other end of the first section of the elastic member; wherein the first section of the elastic member and the second section of the elastic member form an angle, and when the bracket and the solar panel reach a preset angle, the angle is greater than 0° and less than 180°.

[0010] In this embodiment, the solar panel assembly also includes a connector, one end of which is connected to the solar panel, and the other end of the connector is connected to the elastic member. In other words, the connector indirectly connects the elastic member to the solar panel. The elastic member includes two sections of elastic members, a first section of elastic member and a second section of elastic member, the first section of elastic member, one end of the first section of elastic member is connected to the solar panel, one end of the second section of elastic member is connected to the second end of the bracket, and the two sections of elastic members are connected. In fact, the connector and the first section of elastic member and the second section of elastic member have a common endpoint, which can also be understood as: the connector is connected to the elastic member, so that the elastic member is divided into two sections, and the two sections of elastic members form an angle, and when the bracket and the solar panel reach a preset angle, the angle is greater than 0° and less than 180°. That is, the connecting piece is connected to the elastic piece, and when the solar panel and the bracket reach a preset angle, the shape of the elastic piece is changed, so that the elastic piece becomes a V-shaped shape, and under the joint action of the elastic piece and the connecting piece, the bracket generates a downward tilting force, and the tilting direction is toward the side of the solar panel, thereby increasing the friction between the bracket and the ground, and increasing the supporting force for the solar panel to stabilize the solar panel, which can not only ensure the stepless adjustment of the angle between the bracket and the solar panel, but also improve the supporting strength of the bracket.

[0011] In some embodiments, optionally, one end of the connecting member is connected to the bottom of the solar panel, one end of the elastic member is connected to the first end of the bracket, and the other end is connected to the second end of the bracket, so that the tension generated by the elastic member is toward the length direction of the connecting member, that is, the resultant force direction of the tension generated by the elastic member is along the connecting member to the bottom of the solar panel, thereby further improving the supporting strength of the bracket.

[0012] In some embodiments, optionally, the battery panel includes: a plurality of battery panels; and at least one flexible member disposed between two adjacent battery panels.

[0013] In this embodiment, the battery panel includes a plurality of battery panels and at least one flexible member, and the flexible member is arranged between two adjacent battery panels. That is, two adjacent battery panels are connected by a flexible member, and one of the battery panels is flipped onto the other battery panel by utilizing the characteristics of the flexible member, thereby completing the folding of the battery panel, reducing the floor space occupied by the battery panel in the storage state, and improving the portability of the battery panel. At the same time, using the flexible member as a folding structure can greatly reduce the preparation cost of the battery panel and also reduce the difficulty of folding the battery panel.

[0014] In some embodiments, optionally, the number of the flexible members includes a plurality, the plurality of battery plates are arranged at intervals along a first direction, and along the first direction, the intervals between the plurality of battery plates increase or decrease sequentially.

[0015] In this embodiment, the battery panel includes a plurality of flexible members, and the plurality of battery panels are arranged at intervals along a first direction, and the spacing between the plurality of battery panels increases or decreases in sequence along the first direction. That is, the number of the flexible members is at least two, and the widths of the plurality of flexible members gradually increase or decrease along the first direction. The flexible members with gradually increasing or decreasing widths can determine the folding direction of the battery panel, and the user can fold and roll the battery panel from the direction with a small spacing between the battery panels to the direction with a large spacing, thereby reducing the difficulty of folding the battery panel.

[0016] In some embodiments, optionally, the bracket includes: a frame, the frame is a hollow structure; and reinforcing ribs, which are arranged inside the frame and connected to the frame.

[0017] In this embodiment, the bracket includes a frame and reinforcing ribs, wherein the frame is a hollow structure, the reinforcing ribs are arranged inside the frame, and the reinforcing ribs are connected to the frame. That is, the bracket is a hollow structure, consisting of a frame and reinforcing ribs, so that sunlight can directly pass through the hollow structure and shine on the solar panel, or shine on the solar panel after being reflected by the ground, that is, the hollow bracket can avoid blocking sunlight, so that the solar panel receives more sunlight, thereby improving the charging efficiency of the solar panel. At the same time, the reinforcing ribs on the bracket are connected to the frame, thereby improving the strength of the bracket, so that it is sufficient to support the solar panel.

[0018] In some embodiments, optionally, the battery panel includes: a panel including a light-transmitting area; and a double-sided battery sheet arranged in the light-transmitting area.

That is, the battery cell arranged on the battery board can be charged on both sides, thereby improving the utilization rate of sunlight. At the same time, the bifacial battery cell is arranged on the light-transmitting area of ​​the battery board, ensuring that sunlight can irradiate the front and back sides of the bifacial battery cell through the light-transmitting area, greatly improving the charging efficiency of the battery board.

[0020] In some embodiments, optionally, the solar panel assembly further includes: a detector, disposed on the solar panel, capable of detecting the charging efficiency of the solar panel; wherein an indicator mark is disposed on the detector, the indicator mark has at least one indicating position, and the charging efficiency of the solar panel is determined according to the position of the indicator mark.

[0021] In this embodiment, the solar panel assembly also includes a detector, which is arranged on the solar panel, and the detector can detect the charging efficiency of the solar panel. At the same time, an indicator mark is arranged on the detector, and the indicator mark has at least one indicating position, and the charging efficiency of the solar panel is determined according to the position of the indicator mark. That is, the indicator mark on the detector has multiple indicating positions, and during the user's use, the charging efficiency of the current solar panel assembly can be judged according to the position of the indicator mark. It can be understood that the detector has an optimal indicating position, and when the indicator mark is located at the optimal indicating position, the charging efficiency of the solar panel is the highest. By setting the detector, the user can clearly know whether the current inclination angle of the solar panel has the highest charging efficiency, and then the user can independently adjust the inclination angle of the solar panel so that the indicator mark is located at the optimal indicating position to improve the charging efficiency of the solar panel.

[0022] In some embodiments, optionally, the solar panel assembly further includes: a rotating shaft, which is disposed on the bracket; a fixing member, one end of which is fixed to the solar panel; wherein the fixing member has a through hole, and the rotating shaft is disposed in the through hole, so that the bracket can rotate relative to the solar panel.

That is, the rotating shaft of the bracket is arranged in the through hole of the fixing member, and the rotating shaft can move in the through hole to realize the relative rotation of the bracket and the solar panel. This connection method can ensure the rotation of the bracket in the through hole, and at the same time, it can also reduce the number of parts, thereby reducing the production cost of the solar panel assembly.

[0024] In some embodiments, optionally, the solar panel assembly further includes: a first positioning member disposed on the solar panel; a second positioning member disposed at the second end of the bracket; wherein, when the second end of the bracket is in contact with the solar panel, the first positioning member can cooperate with the second positioning member to fix the position of the bracket.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] The first aspect of the present invention provides a solar panel assembly, such as Figure 1 As shown, it includes: a solar panel 1; a bracket 2, a first end 24 of the bracket 2 is rotatably connected to the solar panel 1, and a second end 25 of the bracket 2 can move relative to the solar panel 1 to approach or move away from the solar panel 1; an elastic member 3, one end of the elastic member 3 is connected to the solar panel 1, and the other end of the elastic member 3 is connected to the second end 25 of the bracket 2; wherein, when the bracket 2 and the solar panel 1 reach a preset angle, the elastic member 3 is in a stretched state.

[0044] The solar panel assembly provided by the utility model includes a battery panel 1, a bracket 2 and an elastic member 3, wherein the first end 24 of the bracket 2 is rotatably connected to the battery panel 1, and the second end 25 of the bracket 2 can move relative to the battery panel 1 to get closer to or away from the battery. That is, the bracket 2 is rotatably connected to the battery panel 1, and during the rotation process, the first end 24 and the battery panel 1 are relatively stationary, and the second end 25 and the battery panel 1 move relative to each other, so that the second end 25 of the bracket 2 and the battery panel 1 change position. One end of the elastic member 3 is connected to the battery panel 1, and the other end of the elastic member 3 is connected to the second end 25 of the bracket 2. That is, the two ends of the elastic member 3 are connected to the solar panel 1 and the bracket 2 respectively. When the bracket 2 rotates relatively around the solar panel 1 and the bracket 2 and the solar panel 1 reach the preset angle, the elastic member 3 is in a stretched state, which indicates that the elastic member 3 generates a pulling force on the solar panel 1, so that the bracket 2 and the solar panel 1 have a tendency to close. Since the solar panel 1 and the bracket 2 are both placed on the ground, the solar panel 1 and the bracket 2 form a friction force with the ground. The friction force is equal to the force that generates the closing tendency and is opposite in direction, thereby forming a stable state for the bracket 2 and the solar panel 1. At the same time, the preset angle can be an angle range, such as the preset angle is less than 180° and greater than 0°. By setting the elastic member 3, the bracket 2 and the solar panel 1 can be adjusted steplessly at the preset angle, that is, the angle of the solar panel 1 can be adjusted arbitrarily within the preset angle, and there is no need to set a gear in the rotating structure to fix the solar panel 1. In addition, since the elastic member 3 does not need to set a gear, it is convenient for users to unfold and store the solar panel assembly, reducing the difficulty of unfolding and storing.

[0045] In addition, in some products, the hinge structure can also be set to stepless adjustment, such as a laptop screen, but a damper needs to be additionally set in the hinge structure. The damper can support the weight of the laptop screen, but for solar panel components with large weight and volume, the support strength of the damper is relatively weak, and the use of damper support is prone to damage to the damper. Therefore, on the solar panel 1, a hinge structure with a gear is generally used, and this hinge structure with a gear cannot achieve stepless adjustment, and the inclination angle of the solar panel 1 and the ground cannot be arbitrarily adjusted.

[0046] In some embodiments, optionally, Figure 1 As shown, the solar panel assembly also includes: a connector 4, one end of which is connected to the solar panel 1, and the other end of the connector 4 is connected to the elastic member 3; the elastic member 3 includes: a first section of the elastic member 31, one end of which is connected to the solar panel 1; a second section of the elastic member 32, one end of which is connected to the second end 25 of the bracket 2, and the other end of the second section of the elastic member 32 is connected to the other end of the first section of the elastic member 31; wherein the first section of the elastic member 31 and the second section of the elastic member 32 form an angle, and when the bracket 2 and the solar panel 1 reach a preset angle, the angle is greater than 0° and less than 180°.

[0047] In this embodiment, the solar panel assembly further includes a connector 4, one end of which is connected to the solar panel 1, and the other end of which is connected to the elastic member 3. That is, the connector 4 indirectly connects the elastic member 3 to the solar panel 1. The elastic member 3 includes two sections of elastic members, a first section of elastic member 31 and a second section of elastic member 32. The first section of elastic member 31, one end of which is connected to the solar panel 1, and one end of the second section of elastic member 32 is connected to the second end 25 of the bracket 2, and the two sections of elastic members are connected. In fact, the connector 4 and the first section of elastic member 31 and the second section of elastic member 32 have a common endpoint, which can also be understood as: the connector 4 is connected to the elastic member 3, so that the elastic member 3 is divided into two sections, and the two sections of elastic members form an angle. When the bracket 2 and the solar panel 1 reach a preset angle, the angle is greater than 0° and less than 180°. That is, the connecting member 4 is connected to the elastic member 3. When the solar panel 1 and the bracket 2 reach a preset angle, the shape of the elastic member 3 is changed to make the elastic member 3 into a V-shaped shape. Under the joint action of the elastic member 3 and the connecting member 4, the bracket 2 generates a downward tilting force, and the tilting direction is toward the side of the solar panel 1, thereby increasing the friction between the bracket 2 and the ground, and increasing the supporting force for the solar panel 1 to stabilize the solar panel 1, which can not only ensure the stepless adjustment of the angle between the bracket 2 and the solar panel 1, but also improve the supporting strength of the bracket 2.

[0048] In some embodiments, optionally, one end of the connector 4 is connected to the bottom of the solar panel 1, one end of the elastic member 3 is connected to the first end 24 of the bracket 2, and the other end is connected to the second end 25 of the bracket 2, so that the tension generated by the elastic member 3 is directed in the length direction of the connector 4, that is, the resultant force direction of the tension generated by the elastic member 3 is directed along the connector 4 to the bottom of the solar panel 1, thereby further improving the supporting strength of the bracket 2.

That is, two adjacent battery panels 11 are connected by a flexible member 12, and by utilizing the characteristics of the flexible member 12, one of the battery panels 11 is flipped onto another battery panel 11, thereby completing the folding of the battery panels 11, reducing the floor space occupied by the battery panel 1 in the storage state, and improving the portability of the battery panel 1. Fig. 9 As shown, a schematic diagram of the structure of the solar panel assembly in a folded state is shown. Using the flexible member 12 as the folding structure can greatly reduce the preparation cost of the solar panel 1 and also reduce the difficulty of folding the single solar panel 11.

That is, the number of the flexible members 12 is at least two, and along the first direction, the widths of the plurality of flexible members 12 gradually increase or decrease, and the flexible members 12 with gradually increasing or decreasing widths can determine the folding direction of the battery panel 11, and the user can fold and roll the battery panel 11 from the direction of the small spacing between the battery panels 11 to the direction of the large spacing, thereby reducing the difficulty of folding the battery panel 1.

[0053] In some embodiments, optionally, Figure 1 As shown, the bracket 2 includes: a frame 21 , which is a hollow structure; and reinforcing ribs 22 , which are arranged inside the frame 21 and connected to the frame 21 .

At the same time, the reinforcing rib 22 on the bracket 2 is connected to the frame 21, thereby improving the strength of the bracket 2, so that it is sufficient to support the solar panel 1.

[0055] In some embodiments, optionally, Figure 2 As shown, the battery single board 11 includes: a panel 111 including a light-transmitting area 112 ; and a double-sided battery sheet 113 disposed in the light-transmitting area 112 .

[0056] In this embodiment, the battery board 11 includes a panel 111 and a bifacial battery cell 113, wherein the panel 111 includes a light-transmitting area 112, and the bifacial battery cell 113 is arranged on the light-transmitting area 112. That is, the battery cell arranged on the battery board 11 can be charged on both sides, thereby improving the utilization rate of sunlight. At the same time, the bifacial battery cell 113 is arranged on the light-transmitting area 112 of the battery board 11, ensuring that sunlight can irradiate the front and back sides of the bifacial battery cell 113 through the light-transmitting area 112, thereby greatly improving the charging efficiency of the battery board 11.

[0057] In some embodiments, optionally, Figure 3 , Figure 4 and Figure 5 As shown, the solar panel assembly also includes: a detector 5, which is arranged on the solar panel 1, and the detector 5 can detect the charging efficiency of the solar panel 1; wherein, an indicator mark 51 is arranged on the detector 5, and the indicator mark 51 has at least one indicating position 52, and the charging efficiency of the solar panel 1 is determined according to the position of the indicator mark 51.

[0062] In this embodiment, the solar panel assembly also includes a first positioning member 7 and a second positioning member 8, the first positioning member 7 is arranged on the solar panel 1, and the second positioning member 8 is arranged at the second end 25 of the bracket 2, wherein when the bracket 2 is not opened, that is, when the bracket 2 is completely in contact with the solar panel 1, the first positioning member 7 can cooperate with the second positioning member 8 to fix the position of the bracket 2, thereby preventing the bracket 2 from shaking left and right when the solar panel assembly is in the storage state, thereby improving the portability of the solar panel assembly.

[0063] It is understandable that the first positioning member 7 and the second positioning member 8 can be a pin hole structure, for example, the first positioning member 7 is a protruding pin, and the second positioning member 8 is a concave hole. When the solar panel assembly is in the storage state, the protruding pin enters the concave hole, thereby fixing the position of the bracket 2.

[0064] In some embodiments, optionally, Figure 2 As shown, the solar panel assembly further includes: a junction box 9, which is arranged on the solar panel 1, and one end of the junction box 9 is fixedly connected to the solar panel 1; wherein, a power supply interface 91 is arranged on the junction box 9.

[0065] In this embodiment, the solar panel assembly further includes a junction box 9, which is disposed on the battery panel 1, one end of which is fixedly connected to the battery panel 1, and a power supply interface 91 is disposed on the junction box 9. That is, the junction box 9 can be connected to the electric device through the power supply interface 91, and the electric device is connected to the solar panel assembly through the junction box 9, thereby completing the use of the solar panel assembly to supply power to the electric device, improving the practicality of the solar panel assembly, and at the same time, connecting the electricity generated by the solar panel assembly to the electric device is also more energy-saving and environmentally friendly.

[0066] In a specific application, the utility model provides a roll-up solar panel assembly with a stepless adjustment bracket, including a solar panel, a bracket shaft, a bracket rod, a bracket storage belt, a junction box 9, and a sunlight indicator.

[0067] The solar panel assembly has three bending areas, and the bending areas are folded and rolled in sequence according to the width of the bending areas from small to large.

[0068] The upper end of the bracket storage belt is fixed inside the bracket shaft, and the bracket shaft is fixed to the solar panel assembly through the screws in the groove. The bracket rod is fixed in the bracket shaft through the groove and buckle of the bracket shaft, so that the bracket rod can rotate around the bracket shaft.

[0069] The bracket storage belt is composed of an elastic belt and a fixed belt. The elastic belt is fixed to the bracket shaft, the fixed belt is fixed to the bottom of the solar panel assembly, and the elastic belt is fixed to the cross bar at the bottom of the bracket rod. The three restrict each other to form a triangular structure. When the bracket rod rotates around the bracket shaft, the inclination angle of the solar panel assembly changes accordingly. At this time, the elastic belt fixed to the cross bar at the bottom of the bracket rod is deformed, causing the elastic belt to stretch. The fixed belt fixes the elastic belt to ensure that it will not be infinitely stretched, causing the solar panel assembly to be unable to support. The triangular structure formed by the bracket storage belt realizes stepless adjustment of the inclination angle of the solar panel assembly.

[0070] The hole at the bottom of the support rod can be buckled with the fixing nail at the bottom of the solar panel 1, so that the support rod can be stored and fixed.

[0071] In addition, by calculating the size and thickness of the solar panels of each area block and rationally designing the width of the folding area of ​​the solar panels of each area block, multiple solar panels can be rolled up along the folding area in turn for easy carrying and storage. When needed, they can be put into use by simply unfolding. The bracket 2 is made of lightweight materials and has good stability and load-bearing capacity. By introducing a stepless adjustment mechanism, the real-time adjustment of the inclination angle of the photovoltaic panel is achieved to adapt to different lighting conditions. This design not only improves the power generation efficiency, but also enhances the adaptability and flexibility of the solar panel 1. At the same time, the sunlight indicator can detect the amount of normal solar radiation received by the solar panel 1 in different time periods. By observing the sunlight indicator and analyzing the change of the incident angle at different inclination angles, when the circular shadow of the sun's projection coincides with the dot in the center of the sunlight indicator, the inclination angle of the solar panel assembly at this time has the best reception effect. Therefore, according to the change of the sun's position during the day, the optimal inclination angle scheme can be selected to maximize the power generation efficiency of the solar panel assembly.

[0072] like Figure 4 As shown: at this time, the circular shadow projected by the sun is on the left side of the dot in the center of the sunlight indicator, indicating that the inclination angle of the solar panel is not the optimal inclination angle at this time, and the opening and closing angle of the bracket 2 needs to be properly adjusted.

[0073] like Figure 5 As shown: at this time, the circular shadow cast by the sun coincides with the dot in the center of the sunlight indicator, indicating that the solar panel inclination angle is the optimal inclination angle at this time, and the solar panel 1 can receive more solar normal radiation during this time period.

[0074] Beneficial effects of the utility model:

[0075] 1. Small size and easy to carry: Due to the winding design and lightweight materials, the solar panel components are small in size and light in weight, making them very suitable for carrying and storage, which allows users to easily carry and use solar panel components when engaging in outdoor activities.

[0076] 2. Easy to unfold and store: The solar panel components can be quickly unfolded and stored through simple operations without complicated installation and disassembly processes, which greatly improves the user experience and convenience.

[0077] 3. High power generation efficiency: By introducing a stepless adjustment bracket and an innovative photovoltaic array tilt angle design, the solar panel assembly can adjust the tilt angle of the photovoltaic panel in real time according to different lighting conditions to maximize the amount of normal solar radiation received, which significantly improves the power generation efficiency and provides long-lasting and stable power support for outdoor activities.

[0078] 4. Higher radiation received on both sides: The newly designed bracket has a hollow structure inside, which can effectively reduce the shadow area of ​​sunlight blocked on the back, thereby increasing the power generation on the back of the solar panel 1.
