Technical Field

[0001] The utility model relates to the technical field of passenger car functional accessories, in particular to a photovoltaic sun visor for a vehicle. Background Art

[0002] With the continuous advancement of the automotive industry and the improvement of people's living standards, the number of cars in China continues to grow. Cars have transformed from a luxury item to a popular everyday consumer product. However, in urban areas with scarce land resources, the lack of underground parking spaces forces many vehicles to be parked outdoors. Direct sunlight can cause abnormally high temperatures inside cars, causing discomfort for drivers and accelerating the release of harmful substances such as benzene and formaldehyde from interior components, posing a potential threat to passenger health.

[0003] For these reasons, many car owners without fixed underground parking spaces choose to purchase portable car sunshades to protect their vehicles and mitigate the adverse effects of direct sunlight. Traditional portable car sunshades primarily consist of hood-type and umbrella-type structures. While both effectively block sunlight, they often use tarpaulin as the sunshade fabric, making them inconvenient to use and offering poor functionality. They also fail to effectively utilize solar energy. This leads to increased costs and a decreased user experience, limiting their popularity and frequency of use. Utility Model Content

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0028] See also Figures 1 to 3 A preferred embodiment of a vehicle photovoltaic sun visor, in this embodiment, the vehicle photovoltaic sun visor 1 is used as a whole to be assembled on the roof position of a car body 2, and is used to provide sunshade and power storage functions for the corresponding car when in use.

[0029] The vehicle photovoltaic sun visor 1 of this embodiment includes an assembly frame 4 and a sun visor unit, and the lower surface of the assembly frame 4 is provided with two front and rear structural connectors 10 for fixing the assembly frame 4 on the roof of the car body 2. In different embodiments, the structural connector 10 can be one or a combination of a fastener, a clamping connector, a plug-in connector, a pin fixing member, a suction cup, a knotted rope buckle, a magnetic fixing member, and a threaded connector. The specific selection can be based on actual conditions: for example, on a car model with a luggage rack bracket on the roof, the structural connector 10 can give priority to a fastener or a clamping connector that matches the luggage rack bracket, or a combination of a fastener and a threaded connector, and a combination of a clamping connector and a threaded connector; for example, in a windless or weak wind area, a relatively simple suction cup can be selected as the preferred technical solution for the structural connector 10.

[0030] The front side of the assembly frame 4 is connected to a foldable front sub-bracket 5 via a front hinge 11. The rear side is connected to a rear sub-bracket 6 via an extension plate 8 and two hinges 7. In this embodiment, the assembly frame 4, front sub-bracket 5, and rear sub-bracket 6 are all formed from aluminum alloy to maintain a lightweight design and reduce load while ensuring structural strength.

[0031] After the assembly frame 4 is fixedly assembled on the roof position of the car body 2 through the structural connector 10, the front side sub-bracket 5 and the rear side sub-bracket 6 can be Figure 2 Expand as shown or Figure 1 The styles shown can be stored and folded to suit different usage needs.

[0032] exist Figure 1 In the structural state shown, the front side sub-bracket 5 needs to be folded backward through the front side hinge 11, and then the rear side sub-bracket 6 needs to be folded on both sides using the extension plate 8 with two hinges 7 to overlap the folded front side sub-bracket 5 surface to form the following structure: Figure 1 The structural state is shown, and then the outer side of the rear side auxiliary bracket 6 is fastened and locked using the lock buckle as the storage fixing member 3, so that the vehicle photovoltaic sun visor 1 in the folded and stored state is obtained.

[0033] exist Figure 2 In the structural state shown, the vehicle photovoltaic sun visor 1 can be used to achieve the sunshade and energy storage functions of the car body 2. Figure 2 To ensure the stability of the structure shown, the corresponding front and rear sub-brackets 5 and 6 need to be maintained in position after deployment, so that a certain angle is maintained between the front and rear sub-brackets 5 and the front windshield of the vehicle, thereby ensuring the sunshade effect and the light receiving area of ​​the photovoltaic panel. To achieve this goal, the front and rear sub-brackets 5 and 6 are equipped with deployment fixings. These deployment fixings can be implemented in various ways in different embodiments:

[0034] As the most common technical solution, a folding bracket is the preferred option for the corresponding deployment fixture. This type of folding bracket deployment solution combines structural stability, deployment convenience, and cost-effectiveness. When deployed, the folding bracket provides sufficient support to ensure that the secondary bracket remains in the intended position. At the same time, it can be easily folded and stored when not in use, reducing the space occupied.

[0035] As one of the alternative technical solutions, a ratchet pawl mechanism with a manual release device is used to improve the structure at the corresponding rear hinge 7 and front hinge 11. When in use, the ratchet pawl mechanism is first activated by the manual release device to unfold the corresponding front sub-bracket 5 and the rear sub-bracket 6 to a predetermined angle position to ensure that the sun visor unit can cover the corresponding area of ​​the roof and provide an effective shading effect. Then, the pawl on the ratchet is used to lock the angle position of the front sub-bracket 5 and the rear sub-bracket 6. When storage is required, the ratchet pawl is released to activate the ratchet pawl mechanism so that the front sub-bracket 5 and the rear sub-bracket 6 can be folded and overlapped on the surface of the assembly frame 4, thereby realizing the storage of the vehicle photovoltaic sun visor 1.

[0036] As a second alternative technical solution, the deployment fixing member can also be achieved by a diagonal support rod. The corresponding diagonal support rod can use a fixed length diagonal support rod to cooperate with multiple supporting positions in different positions to achieve the adjustment of the aforementioned angle position; it can also be used as Figure 4 The telescopic structure of the diagonal support rod shown is used to match the single fixed position of the top position. Figure 4 Under the conditions shown, the assembly frame 4 and the front side auxiliary bracket 5 are taken as an example. The corresponding diagonal support push rod is composed of an outer sleeve 14 and a shaft rod 15. The shaft rod 15 can be extended and retracted in the sleeve 14, and a plurality of ejector pin holes are provided on the sleeve 14 along the length direction. During the extension and retraction process, the shaft rod 15 is adjusted by adjusting the ejection of the ejector pin 16 provided thereon at different ejector pin holes of the sleeve 14 to adjust the position so as to adjust the length of the diagonal support push rod, and then cooperate with the first rotating shaft support 12 provided at the outer end of the outer sleeve 14 and the second rotating shaft support 13 provided at the outer end of the shaft rod 15 to adjust the deployment angle position between the assembly frame 4 and the front side auxiliary bracket 5; and when it needs to be stored, it is only necessary to release the first rotating shaft support 12 and / or the second rotating shaft support 13.

[0037] As a third alternative technical solution, the unfolding fixing member can also be a hanging rod with multiple buckles and hanging positions, and the assembly frame 4 and the front side auxiliary bracket 5 are also used as an example. The structural style is as follows Figure 5As shown, the corresponding hanging rod includes a matching hanging rod body 17 and a hook seat 19, one end of the hanging rod body 17 is provided with a first rotating shaft support 12, and the other end is provided with a plurality of hook holes 18 matching the size of the hook seat 19 along the length direction, the first rotating shaft support 12 and the hook holes 18 are respectively provided on the assembly frame 4 and the front side auxiliary bracket 5, and the expansion angle position between the row assembly frame 4 and the front side auxiliary bracket 5 can also be adjusted by hooking the hook seat 19 in different hook holes 18; and when storage is required, the hook seat 19 can be removed from the hanging rod body 17 to perform the storage operation.

[0038] In this embodiment, a U-shaped cavity with a concave accommodating groove is formed on the assembly frame 4, the front side sub-bracket 5 and the rear side sub-bracket 6, and the photovoltaic panel 9 serving as the sun visor unit is correspondingly assembled in the concave accommodating groove, so that when the front side sub-bracket 5 and the rear side sub-bracket 6 are folded and stowed, the photovoltaic panel 9 in the groove can be physically protected. The photovoltaic panel 9 is connected to the light energy conversion circuit through a wire, and is connected to an external power supply or a vehicle power supply through the light energy conversion circuit. The corresponding light energy conversion circuit is encapsulated by a shell and fixedly assembled in the structural space position between the assembly frame 4 and the structural connector 10 after encapsulation. In actual application, the vehicle photovoltaic sun visor 1 can not only provide sunshade protection for the car body 2, but also absorb solar energy through the photovoltaic panel 9 when there is sufficient sunlight, and realize the function of converting solar energy into electrical energy and storing it through the combination of the light energy conversion circuit and the external power supply or the vehicle power supply.

[0039] To ensure effective heat dissipation during operation, the photovoltaic panels 9 are separated from the vehicle roof by an 8-20cm gap between the panels on the corresponding mounting frames. Furthermore, the mounting frames 4, the front sub-brackets 5, and the rear sub-brackets 6 are provided with hollow convection side panels. These sides are porous or grid-like structures to promote air circulation, thereby effectively reducing the surface temperature of the photovoltaic panels and improving the efficiency of power conversion. Furthermore, to further optimize heat dissipation, the back of the photovoltaic panels 9 is also designed with heat sinks, which are tightly bonded to the back of the photovoltaic panels via heat-conductive material to enhance heat dissipation performance.

[0040] In another embodiment, retractable side sunshade curtains can be provided on the left and right sides of the assembly frame 4, the front sub-bracket 5, and the rear sub-bracket 6, respectively, to provide a more comprehensive sunshade effect, and the side sunshade curtains can be folded inward to the surface of the photovoltaic panel 9 in the concave receiving groove and then folded and stored.

[0041] In addition, for some situations where electricity demand is not high, the photovoltaic panels 9 can be set on only one or two sides of the corresponding multiple sunshade units, while the other sides can be replaced with other sunshade materials such as reflective cloth.

[0042] In order to further improve practicality, the corresponding front side sub-bracket 5 and rear side sub-bracket 6 are lined with soft protective lining materials on the non-expanded surfaces. This soft protective lining material can be excessively expanded and attached to the car body 2 when the front side sub-bracket 5 and rear side sub-bracket 6 are excessively expanded to protect the vehicle surface from scratches.

[0043] In embodiments of other passenger cars of different types, the corresponding vehicle photovoltaic sun visor 1 can be set as a single-sided folding structure, that is, only the front side sub-bracket 5 is set without the rear side sub-bracket 6, and the corresponding compatible vehicle model is an SUV model or an MPV model.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
