Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically a photovoltaic panel for a car hood. Background Technology

[0002] As the number of new energy vehicles on the road increases year by year, the number of charging stations, the core of their energy supply, is naturally also crucial. However, due to limitations imposed by mainstream urban power supply methods, most charging stations are still powered by traditional thermal power plants. With the increasing number of new energy vehicles and charging devices, the issues of power supply and environmental protection related to traditional energy generation remain unresolved. Furthermore, the biggest limitation of new energy vehicles lies in the adequacy of charging infrastructure, which is fundamental to ensuring their range. Fixed charging facilities require relatively large investments and ongoing maintenance and operation. Therefore, installing portable mobile charging facilities is an effective measure to address the insufficient range of new energy vehicles and is a pressing issue that needs to be resolved to reduce future reliance on traditional electricity.

[0003] Currently, the main method for vehicle-mounted photovoltaic systems is to install solar photovoltaic panels on the car roof. However, installing photovoltaic panels on the roof also has many problems: for example, installing multiple layers of photovoltaic panels results in a large load on the roof, many connecting components, and a relatively complex structure; the multi-layer structure also leads to greater wind resistance and increased energy consumption; poor adhesion to the vehicle surface leads to poor stability; the actual usable light-receiving area of ​​the photovoltaic panel is limited by factors such as parking position, deployment space, and direction of sunlight, resulting in insufficient utilization of sunlight. Therefore, this utility model proposes a photovoltaic panel for a car hood. Utility Model Content

[0009] As a preferred technical solution of this utility model, a first connector and a second connector are respectively installed on the two sets of second frames, and the first connector and the second connector are fixed together.

[0010] As a preferred technical solution of this utility model, an angle adjustment component is provided between the two sets of movable flexible photovoltaic panels and the first photovoltaic panel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model relates to a photovoltaic panel for a car hood.

[0015] By setting up a first photovoltaic panel, a second photovoltaic panel, and a hinge, the photovoltaic space of the front cover is effectively utilized, increasing the usable area of ​​the photovoltaic panels and thus improving energy utilization.

[0016] By setting up a flexible photovoltaic panel and a bottom flexible photovoltaic panel, the photovoltaic panel can be effectively attached to the front cover of the car, so that the front cover covered with the photovoltaic panel still has reliable hydrodynamic performance and will not significantly increase driving resistance, thus realizing the photovoltaic function of the front cover.

[0031] Please see Figures 1-7In this embodiment, a photovoltaic panel for a car hood is provided, including a first photovoltaic panel 1 and a second photovoltaic panel 2. The first photovoltaic panel 1 includes a bottom flexible photovoltaic panel 10 and a first frame 11 mounted on the outer surface of the bottom flexible photovoltaic panel 10. The second photovoltaic panel 2 includes a movable flexible photovoltaic panel 20 and a second frame 21 mounted on the outer surface of the movable flexible photovoltaic panel 20. The first frame 11 and the second frame 21 are connected by a hinge 3. Both the first frame 11 and the second frame 21 are elastic frames, specifically elastic frames made of TPE material. The bottom flexible photovoltaic panel 10 includes a first elastic base plate 101 and... A first monocrystalline silicon solar cell 102 is disposed on the upper surface of the first elastic base plate 101. A heat insulation film 105 is adhered to the lower surface of the first monocrystalline silicon solar cell 102, and an adhesive film 106 is disposed on the lower surface of the heat insulation film 105. The heat insulation film 105 can play a good heat insulation role and can prevent the temperature of the car hood 5 from having an adverse effect on the photovoltaic panel. The adhesive film 106 is adhered to the upper surface of the car hood 5. A first adhesive film 103 is disposed on the upper surface of the first monocrystalline silicon solar cell 102, and a first protective film 104 is disposed on the upper surface of the first adhesive film 103.

The first elastic base plate 101 and the second elastic base plate 201 can be made of TPE material, thereby enabling effective bending of the first photovoltaic panel 1 and the second photovoltaic panel 2, improving their surface fit with the car hood. Furthermore, the second monocrystalline silicon solar cell 202 and the third monocrystalline silicon solar cell 203 allow the flexible photovoltaic panel 20 to achieve double-sided light absorption, enabling it to be flipped onto the first photovoltaic panel 1. After the upper surface or both sides of the first photovoltaic panel 1 are unfolded, the second photovoltaic panel 2 can absorb light. The number of movable flexible photovoltaic panels 20, the second frame 21 and the hinges 3 are all in one set. By setting the first photovoltaic panel 1, the second photovoltaic panel 2 and the hinges 3, the usable area of ​​the photovoltaic panel can be effectively expanded, thereby improving the energy utilization rate. By setting the movable flexible photovoltaic panel 20 and the bottom flexible photovoltaic panel 10, the flexible bending of the photovoltaic panel can be realized, which can greatly improve the fit between its surface and the car hood.

The two sets of movable flexible photovoltaic panels 20 are a rear-flip photovoltaic panel 22 and a front-flip photovoltaic panel 23, respectively. The sum of the areas of the rear-flip photovoltaic panel 22 and the front-flip photovoltaic panel 23 is equal to the area of ​​the first photovoltaic panel 1. The rear-flip photovoltaic panel 22 and the front-flip photovoltaic panel 23 can be used to unfold the two movable flexible photovoltaic panels 20 on the front and rear sides of the first photovoltaic panel 1. When the vehicle stops, the rear-flip photovoltaic panel 22 is flipped to the surface of the windshield of the vehicle, and the front-flip photovoltaic panel 23 is flipped to the front of the license plate of the vehicle. This allows the first photovoltaic panel 1, the rear-flip photovoltaic panel 22, and the front-flip photovoltaic panel 23 to absorb light at the same time, thereby increasing the light absorption area.

[0033] In this embodiment, there are two sets of movable flexible photovoltaic panels 20, two sets of second frame 21, and two sets of hinges 3. The two sets of movable flexible photovoltaic panels 20 are a first side-flip photovoltaic panel 24 and a second side-flip photovoltaic panel 25, respectively. The sum of the areas of the first side-flip photovoltaic panel 24 and the second side-flip photovoltaic panel 25 is equal to the area of ​​the first photovoltaic panel 1. The first side-flip photovoltaic panel 24 and the second side-flip photovoltaic panel 25 can be used to unfold the two movable flexible photovoltaic panels 20 to the left and right sides of the first photovoltaic panel 1. When the vehicle is stopped, the first photovoltaic panel 1, the first side-flip photovoltaic panel 24, and the second side-flip photovoltaic panel 25 can absorb light simultaneously, increasing the light absorption area.

A pin 45 is installed on the adjustment hole 44, and a fixing hole corresponding to the position of the adjustment hole 44 is opened on the fixing base 41. The pin 45 passes through the adjustment hole 44 and is fixedly installed in the fixing hole. In order to adjust and fix the angle of the first side-flipping photovoltaic panel 24 and the second side-flipping photovoltaic panel 25 after flipping, after flipping, the pin 45 is inserted into the adjustment hole 44 at the corresponding position and fixed in the fixing hole. This can fix the position of the first side-flipping photovoltaic panel 24 and the second side-flipping photovoltaic panel 25 after flipping. It should be noted that the first side-flipping photovoltaic panel 24 and the second side-flipping photovoltaic panel 25 can be unfolded to be on the same horizontal plane as the first photovoltaic panel 1, or the first side-flipping photovoltaic panel 24 and the second side-flipping photovoltaic panel 25 can be perpendicular to the first photovoltaic panel 1 at ninety degrees. This can effectively improve the light absorption effect when there is insufficient space on both sides of the parking space and the sun is facing to the side.
