[0026] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0028] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices). Solar energy is a new type of green, pollution-free, clean, and renewable energy. With the increasing consumption of traditional petrochemical energy, it is imperative to develop and utilize new energy. In the environment of technological innovation and energy crisis, electric vehicles are gradually becoming popular with the support of relevant national policies.

[0029] However, with the popularity of new energy vehicles, the infrastructure of charging piles cannot keep up with the growth rate of new energy vehicles. Many new energy vehicles are difficult to charge, and commercial electricity prices are expensive. Frequent charging will increase electricity costs, and the roof 1 of the car is an idle area and needs to withstand direct sunlight. Direct sunlight will form high temperature in the car. In summer, the temperature in the car is extremely high, which has a great impact on the comfort of the driver and passengers. Solar energy is a clean energy and is easy to obtain. Therefore, some existing new energy vehicles will arrange solar panels on the roof 1 for solar power generation. While charging, it can also avoid direct sunlight on the roof 1 and reduce the temperature inside the car.

[0030] In the prior art, solar panels are usually directly laid on the roof 1, but solar panels cannot work in any environment. They are affected by the weather, and many car models are now equipped with sunroofs, which will be blocked by solar panels.

[0031] like Figure 1 ,2 As shown, the present invention proposes a solar charging mechanism, including a luggage rack 10, a retractable solar panel 20 and a retracting mechanism arranged on the roof 1 of a car, wherein two luggage racks 10 are arranged and are arranged on both sides of the roof 1, and a storage cavity 11 is arranged in the luggage rack 10; the retractable solar panel 20 is located in the storage cavity 11 when retracted, and is laid flat on the roof 1 when unfolded; the retracting mechanism is used to drive the retractable solar panel 20 to retract or unfold. The retractable solar panel 20 is a flexible solar panel, which is a solar panel made of resin-encapsulated amorphous silicon as the main photovoltaic element layer laid flat on a bottom plate made of flexible material. The weight of a flexible solar panel of the same size is only 1 / 10 of that of a traditional solar panel, and the thickness is only 1 / 5 of the original, which is convenient for reducing the weight of the whole vehicle while reducing the space occupied.

[0032] The car luggage rack 10 refers to a bracket installed on the roof 1 for tying large items. The roof 1 bracket is most commonly used for self-driving travel. It is used in conjunction with a roof box and a roof frame to carry travel luggage to increase the space inside the car. It can also carry other sports equipment such as skis, bicycles, sailboats, etc. It is a conventional structure of a vehicle in the prior art.

[0033] Solar cells, also known as "solar chips" or "photovoltaic cells", are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. Single solar cells cannot be used directly as a power source. When used as a power source, several single solar cells must be connected in series or parallel and tightly packaged into a component. Solar panels (also called solar cell modules) are assembled parts that assemble multiple solar cells. They are the core part of a solar power generation system and the most important part of a solar power generation system.

[0034] In the above scheme, the vehicle luggage rack 10 is preferably a flat luggage rack 10 structure, and the arrangement direction of the luggage rack 10 structure is the same as the arrangement direction of the conventional luggage rack 10 structure, both of which are in the direction of the vehicle length. The luggage rack 10 and the roof 1 in the prior art are generally arranged at intervals, and in the present application, it can be set as a luggage rack 10 shape storage structure only. The scheme in the present application is preferably set on an SUV model with a relatively flat roof 1. The roof 1 area of ​​the SUV model is flatter and larger, which is more conducive to the arrangement of large-area solar panels.

[0035] In the above scheme, a switch for controlling the retraction or unfolding of the solar panel can also be set in the vehicle, and the retraction or unfolding of the solar panel can also be controlled according to the light sensor on the vehicle, for example, the solar panel can be folded when the light is weak, and the solar panel can be unfolded when the light is strong. In addition, the speed of the vehicle can be obtained, and then the solar panel can be folded or unfolded according to the speed of the vehicle, for example, the solar panel can be folded when the vehicle speed reaches 60km / h, which can reduce the wind resistance of the vehicle and prevent the solar panel from being damaged by excessive airflow. The rainfall status can also be obtained through the rain sensor of the automatic wiper, and then the solar panel can be folded according to the rainfall status to prevent rainwater from contaminating the solar panel and the retracting mechanism and causing structural damage.

[0036] The solar panel can be rolled up and stored by the rolling mechanism, so that the solar panel can be stored in the storage cavity 11 when encountering bad weather or when the vehicle is driving, so as to avoid the solar panel being damaged by rain, snow or airflow. At the same time, the storage cavity 11 is located in the car luggage rack 10, which is a conventional accessory of many car models. In this way, the solar panel after storage is almost the same as that of a conventional vehicle, and the roof 1 structure will not affect the aesthetics and wind resistance of the whole vehicle.

[0037] like Figure 1 As shown, the reeling mechanism includes a reel 22 located in the storage chamber 11, and the reeling solar panel 20 includes a free end and a reeling end connected to the reel 22. The free end is provided with a slider 21 that slides along the width direction of the vehicle. An elastic return mechanism, such as a torsion spring or a return motor, may be provided on the reel 22 to drive the reel 22 to rotate and reel in the reeling solar panel 20. In the present application, the reeling and unfolding of the reeling solar panel 20 is achieved by the slider 21. When the slider 21 moves away from the storage chamber 11, the reeling solar panel 20 is unfolded, and when the slider 21 moves toward the storage chamber 11, the reeling solar panel 20 is reeled.

[0038] In an optional embodiment of the present invention, the retracting mechanism includes a multi-stage telescopic rod 30, the support end of the multi-stage telescopic rod 30 is hinged in the storage cavity 11, and the telescopic end of the multi-stage telescopic rod 30 is hinged to the slider 21. The multi-stage telescopic rod 30 can be driven by air pressure or hydraulic pressure, and then the slider 21 is controlled to slide by the multi-stage telescopic rod 30. The telescopic rod is set to a multi-stage structure to ensure that the size is shorter when retracted so that it can be placed in the storage cavity 11, and the telescopic rod is longer when it is extended to meet the travel of the solar panel when it is unfolded.

[0039] like Figure 1As shown, two roll-up solar panels 20 are arranged on the same reel 22 and have the same reeling direction. That is, two roll-up solar panels 20 are symmetrically arranged about the axis on the reel 22, and then the two roll-up solar panels 20 are staggered and stacked on the reel 22 when being rolled up. In this way, the solar panel area can be increased to improve the power generation. Figure 1 The middle dotted line shows a schematic diagram of two retracted solar panels 20 in a retracted state. Figure 1 The solid line in the middle represents a schematic diagram of two rolled-up solar panels 20 in an unfolded state.

[0040] like Figure 1 As shown, the two sliders 21 on the two retractable solar panels 20 are respectively connected to one of the multi-stage telescopic rods 30 .

[0041] like Figure 1 As shown, the hinge axes of the supporting ends of the two multi-stage telescopic rods 30 are coaxially arranged with the same reel 22, and the two multi-stage telescopic rods 30 are coaxially arranged and telescope in opposite directions. In this way, the movement directions of the two sliders 21 at the free ends of the multi-stage telescopic rods 30 can be symmetrical about the axis of the reel 22. The slider 21 located above the roof will move left and right along the surface of the roof due to the limitation of the roof. At this time, the slider 21 located outside the vehicle and suspended in the air can also move left and right, ensuring that the retracted solar panel 20 is in a flat state when unfolded.

[0042] In an optional embodiment of the present invention, a magnet is provided on the slider 21. The magnet can make the slider 21 engage with other parts of the roof 1 when the solar panel is unfolded, for example, it can be tightly engaged with the luggage rack 10 on the other side of the roof 1 to form a fixation, or another set of retracting devices can be provided in the luggage rack 10 on the other side of the roof 1, and the slider 21 can be tightly engaged with another slider 21 in the other set of retracting devices to form a fixation, so as to prevent the retracting device from being damaged by force.

[0043] In an optional embodiment of the present invention, a pulley or a slide rail is provided between the slider 21 and the roof 1. This can improve the smoothness of sliding, and at the same time, a pull rope can be provided at both ends of the slider 21 along the slide rail to drive the slider 21 to slide, or a screw rod and the slider 21 are provided in the slide rail to form a screw rod nut mechanism to drive the slider 21 to slide.

[0044] In an optional embodiment of the present invention, a sealing cover is provided on one side of the storage chamber 11 close to the slider 21. The sealing cover can prevent rainwater or debris from entering the storage chamber 11 and damaging the internal structure. When the solar panel needs to be deployed, the slider 21 can push open the sealing cover, or the sealing cover is electrically controlled and is electrically opened when the solar panel needs to be deployed.

[0045] like Figure 1 , 2As shown, two luggage racks 10 are provided and are disposed on both sides of the roof 1, and the retractable solar panel 20 and the retractable mechanism are disposed in both luggage racks 10. In this way, the size of a single solar panel and retractable mechanism is small and the telescopic stroke is also short, so that they are easy to be stored in the storage cavity 11.

[0046] like Figure 2 As shown, the roll-up solar panel 20 covers the skylight of the roof 1 after being unfolded. In existing new energy vehicles, the internal floor height is relatively high due to the need to arrange batteries in the chassis, thus occupying the longitudinal space. Some models will choose to install a panoramic skylight to improve the longitudinal space and light transmittance in the car, while some panoramic skylight models cannot be equipped with sunshades due to space layout reasons, so that the passengers in the car will be directly exposed to the sun in summer. The use scenarios of solar panels and sunshades are almost the same. For example, there is no need to use sunshades and solar panels in rainy weather. In this application, solar panels can be used as sunshades, and there is no need to arrange additional sunshade structures to ensure the longitudinal space in the car.

[0047] The present invention also provides a vehicle, comprising the above-mentioned solar charging mechanism.

[0048] The power of 1 square meter of solar panel is about 140-150W, which is a relatively fixed amount, but the daily light conditions are a variable, rainy, cloudy, morning, evening..., all affect the power generation. Theoretically, 1 square meter of solar panel can generate 1.4-1.5 kWh of electricity in ten hours. Generally, 1-3 square meters of solar panels can be arranged on the roof of the vehicle, which can generate several kWh of electricity every day. For new energy vehicles parked for a long time, it has certain economic benefits. As the charging price of new energy vehicles rises, its economic benefits will also increase.

[0049] In summary, the present invention proposes a solar charging mechanism and a vehicle, wherein the solar panel can be rolled up and stored by a rolling mechanism, so that the solar panel can be stored in a storage cavity 11 when encountering bad weather or when the vehicle is driving, so as to avoid damage to the solar panel due to rain, snow or airflow. At the same time, the storage cavity 11 is located in a car luggage rack 10, which is a conventional accessory of many car models. In this way, the solar panel after storage is almost the same as that of a conventional vehicle, and the roof 1 structure will not affect the aesthetics and wind resistance of the entire vehicle.
