Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic energy storage devices, specifically a foldable photovoltaic energy storage device. Background Technology

[0002] Photovoltaic modules are devices that use the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic modules have a stable and reliable structure and can be easily installed to form a photovoltaic power station to realize photovoltaic power generation.

[0003] Currently, in post-disaster emergency relief environments, nomadic herders' living conditions, outdoor camping and travel environments, and some environments requiring remote work and outdoor office work, there is a lack of stable power supply, necessitating the use of portable power generation equipment. Existing portable power generation equipment mainly relies on gasoline or diesel generators, but gasoline or diesel generators pose certain safety risks and are not clean energy sources. Therefore, providing power to these environments through photovoltaic power generation is a good solution. However, the photovoltaic equipment currently in use is generally large in structure, inconvenient for portable use, and cannot meet market demand. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a foldable photovoltaic energy storage device to solve the problem that the current photovoltaic equipment has a large structure and is not convenient for portable use.

[0005] The technical solution adopted by this utility model is: a foldable photovoltaic energy storage device, including a container, in which a control system, an energy storage battery and a photovoltaic panel are installed. The energy storage battery and the control system are installed in the middle of the container, and storage compartments for accommodating the photovoltaic panels are opened at both ends of the container. The photovoltaic panels are rotatably connected in the storage compartments. Several photovoltaic panels are provided, and connectors are connected between several photovoltaic panels. The photovoltaic panels are rotatably connected to the connectors.

[0006] The above structure has the following beneficial effects:

[0007] 1. The photovoltaic panels, control system, and energy storage battery are integrated into the container. The photovoltaic panels can be unfolded by rotating and reversing to generate photovoltaic power. When it is necessary to move, the photovoltaic panels can be folded and stored, which greatly improves the portability of the device.

[0008] 2. Storage compartments for photovoltaic panels are also set up at both ends of the container, which can protect the photovoltaic panels after they are folded and stored, preventing them from being damaged during movement.

[0009] 3. Several photovoltaic panels can increase the area for collecting sunlight after being unfolded, thereby improving the efficiency of photovoltaic power generation. At the same time, multiple photovoltaic panels are connected by connectors, allowing them to be folded together, which not only effectively reduces the storage volume but also increases the light-receiving area after unfolding, thus improving power generation efficiency.

[0010] Preferably, the connector has a first slot, the photovoltaic panel has a first buckle, and a first elastic element is installed between the first buckle and the photovoltaic panel.

[0011] The engagement between the first slot and the first buckle can limit the relative angle between the photovoltaic panel and the connector after the photovoltaic panel is unfolded, thereby enabling the photovoltaic panel to remain unfolded and thus improve its power generation efficiency. At the same time, the first elastic element can push the first buckle toward the first slot, so that when the first buckle and the first slot are aligned, the first buckle can automatically engage in the first slot.

[0012] Preferably, the connector is also provided with an unlock button, which is slidably connected to the connector, and a second elastic element is provided between the unlock button and the connector.

[0013] The unlock button can push the first latch away from the first slot to achieve the unlocking function. The second elastic element can reset the unlock button after unlocking is completed, so that the first slot can cooperate with the first latch in the future.

[0014] Preferably, a third elastic element is also installed between the connector and the photovoltaic panel.

[0015] The third elastic element allows the adjacent photovoltaic panel to automatically move in the folding direction after the first buckle and the first slot are unlocked. This prevents the first slot and the first buckle from being directly locked together again, and also facilitates the subsequent folding and storage of the photovoltaic panel.

[0016] Preferably, the connector can also be detachably connected to a support frame.

[0017] The support frame can support the connectors and photovoltaic panels, ensuring that the photovoltaic panels can generate photovoltaic power stably.

[0018] Preferably, the bottom of the container is provided with a first groove, in which a support leg assembly is rotatably connected, and one side of the first groove is provided with an inclined surface for abutting against the side of the support leg assembly.

[0019] The support foot assembly allows the photovoltaic panel to remain tilted during operation, thereby improving photovoltaic power generation efficiency. At the same time, the first groove facilitates the storage of the support foot assembly, enhancing the portability of the energy storage device.

[0020] Preferably, the support leg assembly includes a rotating rod and a telescopic rod. One end of the rotating rod has a groove, and the telescopic rod is slidably connected in the groove of the rotating rod. A locking mechanism is also provided between the telescopic rod and the rotating rod.

[0021] The length of the support leg assembly can be adjusted by using telescopic and rotating rods, thereby adjusting the installation angle of the photovoltaic panel to achieve the optimal photovoltaic power generation angle and improve power generation efficiency.

[0022] Preferably, a support leg assembly is also rotatably connected to the support frame.

[0023] The support frame is also connected to a support foot assembly, which allows the support angle of the support frame to be adjusted, making the energy storage device more stable, ensuring the safety of the device during use, and improving its power generation efficiency.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example

[0034] According to the instruction manual Figure 1-2 As shown, this utility model provides a foldable photovoltaic energy storage device, including a container 10. A control system, an energy storage battery, and multiple photovoltaic panels 20 are installed inside the container 10. The control system and the energy storage battery are installed in the middle of the container 10. Storage compartments 11 for accommodating the photovoltaic panels 20 are also provided on both sides of the container 10. The photovoltaic panel 20 closest to the innermost side of the container 10 is rotatably connected to the storage compartment 11. Connectors 30 are provided between adjacent photovoltaic panels 20, and the photovoltaic panels 20 and the connectors 30 are rotatably connected via rotating shafts fixed to the photovoltaic panels 20. This allows adjacent photovoltaic panels 20 to be rotatably connected, enabling them to be folded and stored in the storage compartment 11, or pulled out and unfolded to increase their photovoltaic collection area and improve photovoltaic energy storage efficiency. A protective cover can also be installed on the outermost side of the storage compartment 11 to effectively protect the photovoltaic panels 20 during movement and reduce the probability of damage.

[0035] A first latch 21 is also installed on the photovoltaic panel 20, and a first elastic element 22 is also installed between the photovoltaic panel 20 and the first latch 21. In this embodiment, the first elastic element 22 is a compression spring, which makes the first latch 21 tend to move outward from the photovoltaic panel 20. A first slot 31 for cooperating with the first latch 21 is also provided on the connector 30, and an unlocking button 32 is installed at the end of the first slot 31 away from the photovoltaic panel 20. The end of the unlocking button 32 extends to the outside of the connector 30. A second elastic element 33 is also installed between the unlocking button 32 and the connector 30. In this embodiment, the second elastic element 33 is also a compression spring. When the unlocking button 32 is pressed, the end of the unlocking button 32 located inside the connector 30 can push the first latch 21 embedded in the first slot 31 to move, so that the first latch 21 is pushed out of the first slot 31, thereby unlocking the photovoltaic panel 20 and the connector 30.

[0036] A third elastic element is also installed between the rotating shaft of the photovoltaic panel 20 and the connector 30. The third elastic element is a torsion spring. The setting of the third elastic element makes the photovoltaic panel 20 have a rotation tendency towards the folding direction, so that when the photovoltaic panel 20 and the connector 30 are unlocked, the photovoltaic panel 20 moves towards the folding direction, avoiding the first buckle 21 and the first slot 31 from locking again, and also making it easier for the photovoltaic panel 20 to fold together.

[0037] A support frame 40 is detachably connected to the connector 30. In this embodiment, the support frame 40 is a rectangular frame with three positioning bosses 41 on the top of the rectangular frame. The connector 30 has positioning grooves that match the positioning bosses 41. The connector 30 and the support frame 40 can be installed by inserting the positioning bosses 41 into the positioning grooves. In this embodiment, an auxiliary support 42 is also rotatably connected to the side of the support frame 40, which can support the unfolded photovoltaic panel 20 and can also be rotated to overlap with the support frame 40 for easy storage.

[0038] A first groove 12 is provided at the bottom of the container 10. A support foot assembly 50 is rotatably connected in the first groove 12. An inclined surface is also provided on the side of the first groove 12, so that the first groove 12 can abut against the support foot assembly 50 through the inclined surface, so that the support foot assembly 50 and the bottom surface of the container 10 are arranged at an obtuse angle, thereby improving the support stability of the support foot assembly 50 for the container 10. In this embodiment, the support foot assembly 50 includes a rotating rod 51 rotatably connected in the first groove 12 and a telescopic rod 52 slidably connected to the rotating rod 51. The end of the rotating rod 51 connected to the telescopic rod 52 is a hollow sleeve, and the telescopic rod 52 is slidably connected inside the sleeve.

[0039] A locking mechanism is also installed between the telescopic rod 52 and the rotating rod 51. In this embodiment, the locking mechanism includes a waist-shaped hole on the rotating rod 51, a threaded hole on the telescopic rod 52, and a locking bolt. By tightening the locking bolt on the threaded hole, the relative position between the telescopic rod 52 and the rotating rod 51 can be locked, preventing the support foot assembly 50 from extending or retracting when the photovoltaic energy storage device is working.

[0040] In this embodiment, a support foot assembly 50 is also rotatably connected to the support frame 40, so that the support frame 40 and the container 10 can maintain the same angle, making the support state of the photovoltaic energy storage device more stable.

[0041] Its working principle is as follows: when photovoltaic energy storage is required, the protective cover on the outside of the container 10 is removed, and the outermost photovoltaic panel 20 is pulled to rotate and unfold. When the photovoltaic panel 20 rotates to the horizontal position, the first buckle 21 is engaged in the first slot 31, thereby locking the position of the photovoltaic panel 20 and the connector 30. Then, the support frame 40 is installed on the connector 30, and the support height of the support foot assembly 50 is adjusted, so that photovoltaic energy storage can be carried out. When storage is required, the unlock button 32 is pushed to unlock the connector 30 and the photovoltaic panel 20. Then, the photovoltaic panel 20 is pushed to fold it and can be stored in the storage compartment 11, so as to facilitate the handling or transfer of the photovoltaic energy storage device.

All changes made within the scope of the independent claims of this utility model are within the scope of protection of this utility model.
