DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] Figure 1 A schematic diagram of the structure of a power device provided in an embodiment of the present application is shown. For the sake of convenience, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0023] The photovoltaic mobile power supply device comprises: a base 100 and an upper cover 200 which is rotatably connected to the base 100 and can be turned over relative to the base 100 to form a folded state.

[0024] A first solar panel group 300 made of perovskite material is disposed on the inner folding surfaces of the base 100 and the upper cover 200 , and a second solar panel group 400 is disposed on the outer unfolding surfaces of the base 100 and the upper cover 200 .

[0025] The photovoltaic mobile power device can be adjusted to a folded state or an unfolded state by means of the base 100 and the upper cover 200 that is rotatably connected to the base 100 and can be flipped relative to the base 100 to form a folded state. In some embodiments, when the photovoltaic mobile power device is in the folded state, the angle between the base 100 and the upper cover 200 is close to 0 degrees, and when the photovoltaic mobile power device is in the unfolded state, the angle between the base 100 and the upper cover 200 can be 90 degrees to 180 degrees.

[0026] As a new generation of solar power generation materials, the first solar panel group 300 made of perovskite has a higher energy conversion efficiency. Therefore, when the light intensity is weak, the photovoltaic mobile power device can be adjusted to an unfolded state to generate electricity through the first solar panel group 300 to obtain a higher power generation power. The photovoltaic mobile power device in the folded state is also easy to store.

[0027] Photovoltaic mobile power devices can provide temporary power to indoor IoT devices, sensors, electronic photo frames and mobile devices, and can also provide temporary power to electronic devices outdoors where there is a lack of grid power.

[0028] The base 100 and the upper cover 200 may specifically include a fixing structure for fixing the solar panel group. For example, the base 100 and the upper cover 200 may include a fixing plate or a fixing bracket.

[0029] In one embodiment, the second solar panel assembly 400 is a polycrystalline silicon or monocrystalline silicon solar panel assembly.

[0030] Compared with the first solar panel group 300 made of perovskite, the polycrystalline silicon or monocrystalline silicon solar panel group has a lower energy conversion efficiency, but has a lower cost and better versatility. Under outdoor conditions with sufficient light, the photovoltaic mobile power supply device can be adjusted to a folded state, unfolded at a certain angle, and placed in an inverted V shape to generate electricity through the second solar panel group 400. Even if the energy conversion efficiency of the second solar panel group 400 is low, it can meet the power generation needs. At the same time, it can also cope with more dangerous outdoor use environments and increase its service life.

[0031] In one embodiment, the first solar panel group 300 includes an upper cover inner solar panel 310 disposed on the inner folding surface of the upper cover 200 and a base inner solar panel 320 disposed on the inner folding surface of the base 100, and the upper cover inner solar panel 310 and the base inner solar panel 320 are opposite to each other in the folded state; the second solar panel group 400 includes an upper cover back solar panel 410 disposed on the back side of the upper cover 200 and a base back solar panel 420 disposed on the back side of the base 100, and the upper cover back solar panel 410 and the base back solar panel 420 are opposite to each other in the folded state.

[0032] The upper cover inner solar panel 310 and the base inner solar panel 320 may be perovskite solar panels, and the upper cover back solar panel 410 and the base back solar panel 420 may be polycrystalline silicon or monocrystalline silicon solar panels.

[0033] It is understandable that, when the photovoltaic mobile power supply device is in the unfolded state, the inner solar panel 310 of the upper cover and the inner solar panel 320 of the base are located on the same side, and the back solar panel 410 of the upper cover and the back solar panel 420 of the base are located on the other opposite side.

[0034] In some embodiments, the upper cover back solar panel 410 and the base back solar panel 420 may be thin film solar panels.

[0035] In one embodiment, a power management module 510 is provided in the upper cover 200 and / or the base 100, and an output interface 520 electrically connected to the power management module 510 is provided on the upper cover 200 and / or the base 100, and the first solar panel group 300 and the second solar panel group 400 are electrically connected to the power management module 510, respectively.

[0036] Specifically, the power management module 510 may include a processor and an electric energy conversion circuit, the electric energy conversion circuit is respectively connected to each solar power generation module and each output interface 520, and the processor is connected to the electric energy conversion circuit. When an external power-consuming device is connected to the output interface 520, the processor can control the output of the electric energy conversion circuit according to the actual needs of the external power-consuming device to meet the power demand of the external power-consuming device.

[0037] The specific positions of the power management module 510 and the output interface 520 can be set according to actual needs.

[0038] In some embodiments, the output interface 520 includes a USB interface, a Type-C interface, and the like.

[0039] In some embodiments, the base 100 is provided with a plurality of output interfaces 520 , which can charge a plurality of devices simultaneously.

[0040] In one embodiment, an energy storage module is disposed in the upper cover 200 and / or the base 100, and the energy storage module is electrically connected to the power management module 510. The energy storage module may include a battery pack.

[0041] Specifically, the energy storage module can be connected to the processor and the power conversion circuit. When the total power generation of the photovoltaic mobile power supply device can meet the power demand of the external power-consuming device or no external power-consuming device is connected to the photovoltaic mobile power supply device, the processor can control the power conversion circuit to charge the energy storage module. When the total power generation of the photovoltaic mobile power supply device cannot meet the power demand of the external power-consuming device, the processor can control the energy storage module to supply power to the external power-consuming device.

[0042] In some embodiments, the energy storage module is disposed in the base 100 .

[0043] In one embodiment, a display module electrically connected to the power management module 510 is disposed on the upper cover 200 and / or the base 100. The display module may include a liquid crystal display for realizing human-computer interaction.

[0044] The display module can be connected to the power management module 510, and can be used to display the real-time power generation power of the photovoltaic mobile power device, and can also be used to display the remaining power of the energy storage module or other real-time working parameters of the photovoltaic mobile power device.

[0045] In one embodiment, the photovoltaic mobile power supply device includes a rotating mechanism 600 that hinges the upper cover 200 and the base 100 , and the rotating mechanism 600 can control the angle between the upper cover 200 and the base 100 .

[0046] According to the light irradiation angle, the angle between the upper cover 200 and the base 100 can be controlled by the rotating mechanism 600 so that the upper cover 200 is perpendicular to the light irradiation direction, so that the photovoltaic mobile power supply device can generate electricity at the maximum power.

[0047] In one embodiment, the rotating mechanism 600 includes an electric rotating shaft, which is electrically connected to the power management module 510. The power management module 510 can control the rotation of the electric rotating shaft to allow the upper cover 200 and the base 100 to unfold relative to each other when the power generation power of the photovoltaic mobile power supply device is less than a preset threshold.

[0048] It is understandable that, due to the high energy conversion efficiency of the first solar panel group 300 on the inside, when the power generation of the photovoltaic mobile power device is less than the preset threshold, the power management module 510 can automatically control the upper cover 200 and the base 100 to unfold relative to each other through the electric shaft to increase the power generation of the photovoltaic mobile power device to meet the power demand. The preset threshold can be set according to actual needs.

[0049] In one embodiment, a photosensitive module capable of sensing the ambient light intensity is further provided on the upper cover 200 and / or the base 100. The photosensitive module is electrically connected to the power management module 510. The power management module 510 can control the rotation of the electric shaft to fold or unfold the upper cover 200 and the base 100 based on the ambient light intensity sensed by the photosensitive module.

[0050] When the angle between the upper cover 200 and the base 100 is fixed, the ambient light intensity is usually positively correlated with the power generation of the photovoltaic mobile power supply device. Therefore, the power management module 510 can determine whether the current power generation meets the basic power demand based on the ambient light intensity and the angle between the upper cover 200 and the base 100. When the ambient light intensity is low, the power management module 510 can control the electric shaft to rotate to unfold the upper cover 200 and the base 100, and use the first solar panel group 300 as the main power generation module to improve the power generation efficiency. When the ambient light intensity is sufficient, the power management module 510 can control the electric shaft to rotate to unfold the upper cover 200 and the base 100, and use the second solar panel group 400 as the main power generation module to protect the first solar panel group 300.

[0051] In one embodiment, a support structure for contacting with the external environment is disposed on the base 100 .

[0052] The support structure may include anti-skid pads or support feet for contacting the ground, and may also include a fixing structure for fixing to the external environment.

[0053] In some embodiments, protective frames are further provided on the sides of the base 100 and the upper cover 200 , and anti-collision parts are provided at the corners of the sides of the upper cover 200 and the base 100 .

[0054] When the photovoltaic mobile power supply device is frequently moved, the first solar panel group 300 and the second solar panel group 400 are easily damaged by external impact, and are difficult to repair after being damaged. The protective frame and the anti-collision part can improve the portability of the photovoltaic mobile power supply device, reduce the risk of damage to the first solar panel group 300 and the second solar panel group 400, and increase the service life.

[0055] In summary, the photovoltaic mobile power supply device can be adjusted to a folded state or an unfolded state through the base 100 and the upper cover 200 which is rotatably connected to the base 100 and can be flipped relative to the base 100 to form a folded state.

[0056] In the folded state, the photovoltaic mobile power device can be fixed in an outdoor environment by a supporting structure. At this time, the photovoltaic mobile power device mainly generates electricity by the second solar panel group 400 on one side. The photovoltaic mobile power device can also be unfolded at a certain angle and placed in an inverted V manner to generate electricity by the second solar panel groups 400 on both sides. The power generation efficiency of the second solar panel group 400 is lower than that of the first solar panel group 300, but the strong light in the outdoor environment is sufficient to meet the power generation needs, and the second solar panel group 400 is more adaptable to the outdoor environment than the first solar panel group 300.

[0057] In the unfolded state, the side of the second solar panel group 400 can be turned toward the light source to generate electricity, and the side of the first solar panel group 300 can be turned toward the light source to generate electricity. Compared with the second solar panel group 400, the first solar panel group 300 made of perovskite material has a higher energy conversion efficiency, and therefore has a higher power generation efficiency in an indoor environment with weak light intensity.

[0058] The photovoltaic mobile power supply device of this embodiment can be used as a mobile power supply and its placement can be changed according to needs. At the same time, it can switch to different postures according to different lighting conditions to generate electricity with high efficiency.
