The rotating base is rotatably connected to one end of the propeller arm, and the blade is rotatably connected to the rotating base. The blade has a flight state and a retracted state. In the flight state, the blade is arranged perpendicular to the propeller arm. In the retracted state, the blade is arranged parallel to the propeller arm, and the blade coincides with the propeller arm along the extension direction of the propeller arm.

[0008] In some embodiments, the energy storage host has a recessed portion; in the retracted state, the walking wheel is partially housed in the recessed portion; and in the extended state, the walking wheel is fully extended out of the recessed portion.

[0009] In some specific embodiments, the energy storage device has recesses at both the front and rear ends, and the walls of the recesses are provided with telescopic grooves. The energy storage device also includes a telescopic frame, one end of which is retractably installed in the telescopic groove, and the other end is connected to two wheels.

[0010] In some specific embodiments, the energy storage device further includes a telescopic structure, one end of which is connected to the telescopic frame and the other end of which is connected to the walking wheel.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] This utility model discloses an energy storage device, with reference to... Figures 1-3 As shown, the system includes an energy storage unit 1, wheels 2, and a blade assembly 3. The energy storage unit 1 has a discharge port 101, and a battery module is housed within it, capable of discharging through the discharge port 101. The wheels 2 have retracted and extended states. Figure 14 As shown, in the retracted state, the walking wheels 2 partially retract into the energy storage unit 1, as... Figure 13 As shown, in the extended state, the walking wheel 2 extends out of the energy storage host 1 and can drive the energy storage host 1 to move. The propeller assembly 3 has a folded state and an unfolded state, as shown. Figure 12As shown, in the folded state, the blade assembly 3 is arranged along the extension direction of the side wall of the energy storage host 1, as follows: Figure 11 As shown, in the deployed state, the propeller assembly 3 is open relative to the energy storage host 1 and can propel the energy storage device into flight. It is understood that since the wheels 2 have retracted and extended states, and the propeller assembly 3 has deployed and folded states, the operating states can be manually switched according to actual needs, allowing the energy storage device to switch between ground-based walking and low-altitude flight. This gives the energy storage device both ground-based walking and low-altitude flight capabilities, eliminating the need for manual handling and improving user satisfaction. When the energy storage device needs to be stored, simply push the wheels 2 back to the retracted state and fold the propeller assembly 3 into the folded state, thus reducing the storage volume of the energy storage device and facilitating its use.

[0037] It should be noted that the walking wheel 2 in this embodiment is a self-propelled wheel with a drive unit, and the blade assembly 3 also has its own drive unit. When the walking wheel 2 or the blade assembly 3 is installed on the energy storage host 1, the drive unit needs to be connected to the battery module built into the energy storage host 1 through the plug-in terminal; or the walking wheel 2 and the blade assembly 3 themselves have their own batteries as power supply devices.

[0038] refer to Figures 7-9 As shown, the energy storage unit 1 is provided with a connecting arm 102, and the blade assembly 3 includes a blade arm 301 and a blade 302. One end of the blade arm 301 is rotatably mounted on the connecting arm 102, and the other end is connected to the blade 302. It can be understood that by providing the connecting arm 102 on the energy storage unit 1, the blade arm 301 can be rotatably connected to the connecting arm 102, making it easy to fold or unfold the entire blade assembly 3.

[0039] Optional, see reference Figures 10-11 As shown, the propeller 302 includes a rotating base 3021 and a blade 3022. The rotating base 3021 is rotatably connected to one end of the propeller arm 301, and the blade 3022 is rotatably connected to the rotating base 3021. The blade 3022 has a flight state and a retracted state. In the flight state, the blade 3022 is perpendicular to the propeller arm 301. In the retracted state, the blade 3022 is parallel to the propeller arm 301, and the blade 3022 coincides with the propeller arm 301 along the extension direction of the propeller arm 301. It can be understood that when the propeller assembly 3 is in the folded state, the blade 3022 can be rotated relative to the rotating base 3021 to make it parallel to the propeller arm 301. This allows the entire propeller assembly 3 to have a smaller volume in the folded state, thereby further reducing the storage volume of the energy storage device and facilitating its use.

[0040] refer to Figure 5As shown, two blade assemblies 3 are provided on both the left and right sides of the energy storage host 1. The two blade assemblies 3 on the same side wall partially overlap in the front-rear direction of the energy storage host 1 when folded. It can be understood that the energy storage host 1 has four blade assemblies 3. Using all four blade assemblies 3 to drive the energy storage host 1 during low-altitude flight ensures its stability, thereby improving its stability. The partial overlap of the two blade assemblies 3 on the same side wall in the front-rear direction further reduces the footprint of the blade assemblies 3 in the folded state, thus further reducing the storage volume of the energy storage device.

[0041] refer to Figures 10-11 As shown, the energy storage host 1 has a recessed portion 103. In the retracted state, the wheels 2 are partially housed in the recessed portion 103, and in the extended state, the wheels 2 are fully extended out of the recessed portion 103. Because the energy storage host 1 in this embodiment has a recessed portion 103, and the wheels 2 are retractably mounted on the energy storage host 1, when the energy storage device needs to move, the operator can pull out the wheels 2 to switch to the extended state. When the energy storage device is being stored or charged, the operator can push the wheels 2 back to switch to the retracted state. Since the wheels 2 are partially housed in the recessed portion 103 in the retracted state, the storage volume of the energy storage device is reduced.

[0042] Optional, see reference Figures 13-14 As shown, the energy storage device has recesses 103 at both the front and rear ends, and telescopic grooves 104 are provided on the walls of the recesses 103. The energy storage device also includes a telescopic frame 4, one end of which is retractably installed in the telescopic groove 104, and the other end is connected to two wheels 2. By setting the telescopic frame 4, the wheels 2 can switch between the retracted state and the extended state. In actual operation, the operator only needs to pull the telescopic frame 4 out of the telescopic groove 104 or push it back, which is very convenient.

[0043] It should be noted that the cooperation between the telescopic frame 4 and the telescopic groove 104 is similar to the pull-out structure of a drawer. In other words, the structure of the telescopic frame 4 can be selected according to existing technology, and there is no need to limit the specific cooperation method between the telescopic frame 4 and the telescopic groove 104.

[0044] Optional, see reference Figures 13-14As shown, the energy storage device also includes a telescopic structure 5. One end of the telescopic structure 5 is connected to the telescopic frame 4, and the other end is connected to the traveling wheel 2. By adding the telescopic structure 5, the telescopic frame 4 can be pulled out of the telescopic slot 104 and then unfolded again, increasing the distance between the two traveling wheels 2 on the same telescopic frame 4, thereby improving the stability of the energy storage device when traveling on land. It should be noted that the telescopic structure 5 in this embodiment is a telescopic rod, i.e., a structure including multiple sleeve rods. This structure is existing technology and will not be described in detail here.

[0045] refer to Figures 13-14 As shown, the telescopic frame 4 includes a telescopic body 401 and two connecting frames 402. The telescopic body 401 is slidably mounted on the telescopic groove 104. The two connecting frames 402 are connected to the opposite sides of the telescopic body 401. Each connecting frame 402 has a mounting hole, and one end of the telescopic structure 5 is inserted into the mounting hole. It can be understood that the telescopic body 401 and the telescopic groove 104 form a drawer-type structure, facilitating pulling out and pushing back. The two connecting frames 402 facilitate the installation of the telescopic mechanism. Furthermore, when the traveling wheels 2 are fully extended (opening 601), the surfaces of the two traveling wheels 2 with the telescopic groove 104 are relatively far apart, which helps improve the stability of the entire energy storage unit 1 during movement.

[0046] refer to Figure 6 As shown, the energy storage host 1 is provided with an installation part 6, and a first photovoltaic panel 7 is provided on the top of the installation part 6. The top area of ​​the energy storage host 1 is relatively large. The first photovoltaic panel 7 on the top of the energy storage host 1 can charge the battery module inside the energy storage host 1, thereby extending the discharge time of the energy storage host 1.

[0047] Optional, see reference Figure 6 As shown, the mounting part 6 has a mounting cavity with an opening 601 on its side wall. A retractable second photovoltaic panel 8 is housed within the mounting cavity. In actual use, the second photovoltaic panel 8 can be pulled out of the mounting cavity, increasing the power generation efficiency of the energy storage host 1 and thus extending its discharge time. Further optionally, the mounting cavity has a rectangular cross-section, with openings 601 on all four side walls, and four second photovoltaic panels 8 are provided. Therefore, increasing the number of second photovoltaic panels 8 further improves the power generation efficiency of the energy storage device, thereby extending the discharge time of the energy storage host 1. Even more optionally, each second photovoltaic panel 8 includes multiple telescopic sub-panels; that is, in two adjacent sub-panels, one sub-panel has a receiving groove, and the other sub-panel can retract into the receiving groove. Thus, when the second photovoltaic panel 8 is fully extended, it has a large area, which is beneficial for improving the power generation efficiency of the energy storage device and extending the discharge time of the energy storage host 1.

[0048] Of course, in other embodiments of this utility model, the number of second photovoltaic panels 8 and the number of sub-panels included in the second photovoltaic panels 8 can be adjusted according to actual needs.

[0049] Further optional, see reference Figure 6 As shown, the energy storage unit 1 has a first mounting groove 105, and the mounting part 6 is movably mounted in the first mounting groove 105. The mounting part 6 has a receiving state that is housed within the first mounting groove 105 and a pushed-out state that extends out of the first mounting groove 105. It can be understood that the mounting part 6 is movably mounted in the first mounting groove 105, and when not in use, the mounting part 6 can be housed in the first mounting groove 105. On the one hand, this improves the aesthetics of the energy storage unit 1, reduces the space occupied by the energy storage unit 1, and facilitates the storage of the energy storage unit 1. On the other hand, it can prevent external pollutants, moisture, and other structures from entering the mounting cavity, reducing the probability of the second photovoltaic panel 8 being contaminated and reducing the probability of the second photovoltaic panel 8 being jammed by foreign objects during the extraction process.

[0050] Further optional, see reference Figure 6 As shown, a first rotating rod 9 is provided on the bottom wall of the first mounting groove 105, and a second rotating rod 10 connected to the first rotating rod 9 is provided on the mounting part 6. When the second rotating rod 10 is relative to the first rotating rod 9, the mounting part 6 can move to the ejected state. It can be understood that in actual operation, when the operator operates the mounting part 6 to detach from the first mounting groove 105, due to the provision of the first rotating rod 9 and the second rotating rod 10, the angle of the first rotating rod 9 relative to the bottom wall of the first mounting groove 105 and the angle of the second rotating rod 10 relative to the first rotating rod 9 can be adjusted to allow the second photovoltaic panel 8 to adjust its angle according to the position of the sun. This ensures that the second photovoltaic panel 8 always has a suitable angle corresponding to the sun, thereby improving the light utilization rate of the second photovoltaic panel 8 and improving the power generation efficiency of the energy storage device.

[0051] To ensure that the second photovoltaic panel 8 can be maintained at a specified angle, a damping component is also installed on the shaft of the second rotating rod 10. This reduces the probability of the second photovoltaic panel 8 rotating under the action of external forces during power generation, ensuring that the second photovoltaic panel 8 can always have a suitable angle to face the sun, thereby improving the light utilization rate of the second photovoltaic panel 8 and improving the power generation efficiency of the energy storage device.

[0052] Of course, in the embodiments of this utility model, a telescopic rod is provided on the bottom wall of the first mounting groove 105, and the mounting part 6 is hinged to the telescopic rod. In actual use, the telescopic rod can be extended by operating the mounting part 6, so that the mounting part 6 extends out of the first mounting groove 105. Then, the mounting part 6 can be rotated so that it always has a suitable angle to correspond to the sun. That is to say, the structure for the mounting part 6 to extend, retract, and rotate within the first mounting groove 105 can be selected according to actual needs, and does not require the existing structure of the first rotating rod 9 cooperating with the second rotating rod 10.

[0053] refer to Figures 3-4 As shown, the energy storage host 1 is equipped with discharge ports 101 of various specifications. The discharge ports 101 can be of various forms, such as Type-A, Type-B, Type-C, three-prong sockets, and two-prong sockets. Therefore, the energy storage host 1 of this embodiment can charge mobile devices (such as mobile phones and computers) or electrical appliances (such as refrigerators and electric heaters), thereby enabling the energy storage device of this embodiment to charge a variety of electrical devices, expanding the compatibility of the energy storage device, and improving user satisfaction.

[0054] Optional, see reference Figures 3-4 As shown, the energy storage host 1 is provided with a second mounting groove 106, and multiple discharge ports 101 are located on the groove wall of the second mounting groove 106. The energy storage host 1 is provided with a rotatably connected sealing cover 11, which can be fastened to the second mounting groove 106 to hide the multiple discharge ports 101. It can be understood that by setting the sealing cover 11, the multiple discharge ports 101 can be hidden when the energy storage device is not in use, preventing dirt or moisture from entering the discharge ports 101, thereby ensuring the cleanliness of the discharge ports 101, reducing the failure rate of the discharge ports 101, and ensuring that the discharge ports 101 can discharge stably. In order to prevent the sealing cover 11 from falling off and exposing the discharge ports 101 when the energy storage device is moving or flying, a locking protrusion can be provided on the sealing cover 11, and a locking hole can be provided on the second mounting groove 106, so that the sealing cover 11 can be stably fastened to the energy storage host 1 through a snap-fit ​​structure. Of course, the sealing cover 11 can also be fixed by screws, fixing pins, or other structures.

[0055] refer to Figure 5 As shown, a third photovoltaic panel 12 is provided on the propeller arm 301 of the propeller assembly 3. The second photovoltaic panel 8 and the third photovoltaic panel 12 are provided on the outer wall of the propeller arm 301, which can further improve the power generation efficiency of the energy storage device, thereby extending the discharge time of the energy storage host 1.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
