Description

Technical Field

[0001] This invention relates to the field of energy storage battery technology, and more particularly to an energy storage power source. Background Technology

[0002] Portable energy storage power supplies, with their portability, are widely used in outdoor travel and emergency power supply applications. These products typically come standard with a Universal Serial Bus (USB) interface to meet the power supply needs of various digital devices, lighting equipment, and more. However, in existing designs, the USB interface is directly located on the outside of the casing. When exposed to complex outdoor environments for extended periods, debris and moisture can easily enter the interface cavity, causing contact corrosion, abnormal conductivity, and reduced product reliability. The exposed conductive contacts are also susceptible to accidental short circuits caused by metal debris, potentially leading to short circuits, high temperatures, and other safety hazards. Summary of the Invention

[0003] The present invention provides an energy storage power source to solve at least one of the problems mentioned in the background art.

[0004] The energy storage power supply according to this application includes a housing, a battery module, a voltage conversion circuit, and an output component. The housing has a receiving cavity and an opening, the opening connecting the receiving cavity to the outside. The battery module is disposed within the receiving cavity. The voltage conversion circuit is disposed within the receiving cavity, electrically connected to the battery module, and converts the battery module's electrical energy. The output component is electrically connected to the voltage conversion circuit, and the output component includes at least two output ports and an operating element. The operating element protrudes from the housing, and the output ports are located within the housing. The output ports are movable relative to the housing under the action of the operating element, so as to move the output ports to a position aligned with or offset from the opening.

[0005] In the energy storage power supply of this application embodiment, the output port can be moved to a position aligned with or offset from the opening under the action of the operating component. When an external device needs to connect to the energy storage power supply, the operating component moves the output port to align with the opening, thereby enabling the energy storage power supply to connect to the external device. When the output port is in an idle state, the operating component moves the output port away from the opening, thereby causing the output port to be covered by the housing, achieving the concealment of the output port in the non-use state. In this way, the operating component can achieve the exposure or covering of the output port. The operation method is simple, and the output port can be kept covered in the non-use state, effectively preventing problems such as contact corrosion and accidental short circuits caused by long-term exposure of the output port, improving the working safety and reliability of the output port, and helping to extend its service life and meet relevant usage requirements.

[0006] In some embodiments, the output component includes a first output element and a second output element disposed within the receiving cavity, the first output element being electrically connected to the voltage conversion circuit, the second output element being movably electrically connected to the first output element, and the output port and the operating element being disposed on the second output element.

[0007] In some embodiments, the actuating element can cause the second output element to slide relative to the first output element, so that the output port slides to a position aligned with or offset from the opening.

[0008] In some embodiments, the operating member can drive the second output member to rotate relative to the first output member, so that the output port rotates to a position aligned with or offset from the opening.

[0009] In some embodiments, the second output component includes a male plate and a rotating disk, the male plate being electrically connected to the first output component and rotatable relative to the male plate, the rotating disk being fixedly connected to the male plate, and the output port being disposed on the male plate.

[0010] In the above embodiment, the public board is electrically connected to the first output component, and the output port is set on the public board. The power is output from one side of the first output component to the output port through the public board, ensuring normal power supply to the output port, and the overall structure is relatively compact.

[0011] In some embodiments, the public board is provided with a conductive part that is electrically connected to the output port. The conductive part and the output port are respectively located on opposite sides of the public board. The conductive part includes a contact pin. The first output component is provided with an annular conductive ring. The contact pin contacts the conductive ring.

[0012] In the above embodiments, the first output component and the second output component ensure electrical connection of the output port in various states through the contact between the conductive ring and the contact pin, and the connection method is simple and highly reliable.

[0013] In some embodiments, the rotating disk is provided with a shielding portion protruding toward the side where the operating member is located. The shielding portion and the output port are arranged around the rotation center of the second output member, and the shielding portion is used to block the opening.

[0014] In the above embodiment, the blocking part is rotated to a position aligned with the opening to block the opening. The blocking operation is simple and convenient. The blocking part and the output port are integrated on the rotating disk, making the overall structure more compact.

[0015] In some embodiments, the first output component includes a fixed disk and a mother plate. The fixed disk is fixed inside the housing, and the mother plate and the fixed disk are fixedly connected. The mother plate is provided with a conductive ring that is electrically connected to the output port. A limiting component is installed on the fixed disk. The limiting component is used to restrict the rotation position of the second output component when it abuts against the second output component, so that the output port is exposed through the opening.

[0016] In the above embodiment, the rotation position of the second output component is limited by a small limiting component installed on the fixed plate, ensuring that the output port can be stably maintained in a position aligned with or deviated from the opening, ensuring a stable connection between the output port and the external device, and ensuring the long-term effectiveness of the protection state.

[0017] In some embodiments, the limiting member includes a positioning post and a body rotatably connected to the positioning post. The positioning post is fixed to the fixed plate, and the body is provided with a connecting post for the second output member to abut against.

[0018] In the above embodiment, the limiting member abuts against the second output member through the connecting post to restrict the rotation of the second output member. The limiting method is simple, the movement form is intuitive, and the overall structure of the limiting member is compact, which is conducive to further improving the structural compactness.

[0019] In some embodiments, the rotating disk is formed with a guide groove, in which a plurality of first guide blocks and a plurality of second guide blocks are provided. The first guide blocks and the second guide blocks are alternately spaced along the circumference of the rotating disk. The first guide blocks, the second guide blocks and the rotating disk together define a guide groove for the connecting post to slide along a first circumferential direction. The connecting post slides along the guide groove and abuts against one of the first guide blocks to limit the rotational position of the second output member.

[0020] In the above embodiment, the position of the output port is maintained by the contact between the end face of the first guide block and the connecting column, and the movement trajectory of the connecting column is restricted by the guide rail groove, so as to ensure the smooth rotation of the second output component relative to the first output component and the reliability of the position maintenance of the second output component, thereby meeting the user's need for rapid operation.

[0021] In some embodiments, the guide groove includes a first guide section and a second guide section. The first guide section is formed on the side of the first guide block and the second guide block facing the center of the rotating disk, and the second guide section is formed on the side of the first guide section away from the center of the rotating disk. Both ends of the second guide section are connected to the first guide section. The connecting post can slide from one end of the second guide section to the other end of the second guide section to abut against one of the first guide blocks.

[0022] In the above embodiment, when the connecting column moves along the first guide segment to the second guide segment, it can smoothly abut against the first guide block under the action of the second guide segment. Through the cooperation of the first guide segment and the second guide segment, the movement trajectory of the connecting column is stabilized, and the position of the output port is kept stable.

[0023] In some embodiments, the first guide block has a first guide arc surface opposite to a first end of the second guide block, the first guide arc surface being offset away from the center of the rotating disk along the first circumferential direction, and the first guide arc surface forming the side surface of the second guide segment; The second end of the second guide block has a second guide arc surface opposite to the first guide block, and the second guide arc surface forms the side of the second guide segment; the second guide arc surface deviates from the center of the rotating disk along the first circumferential direction, and the connecting post can be inserted into the gap between the second guide arc surface and the first guide block during sliding to abut against the first guide block.

[0024] In the above embodiment, the smooth movement of the connecting post in the guide groove is achieved through the cooperation of the first guide arc surface and the second guide arc surface, ensuring that the connecting post is smoothly locked by the first guide block after reaching the predetermined position, thus providing a guarantee for stable power supply to the output port.

[0025] In some embodiments, the output component further includes an elastic element connecting the housing and the rotating disk. The elastic element is configured to elastically deform when the rotating disk rotates along the first circumferential direction and to recover its deformation when the connecting post disengages from the first guide block, so that the connecting post rotates along the first guide segment along the second circumferential direction and drives the rotating disk and the operating member to rotate and reset along the second circumferential direction.

[0026] In the above embodiment, the second output component is reset by means of an elastic element. The elastic element can store force when the operating component is rotated by an external force, and release the elastic force after the connecting column is disengaged from the snap-fit ​​position, thereby resetting the second output component and making the opening blocked by the blocking part. No additional reset mechanism is required, and the operation is simple and the cost is low.

[0035] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the energy storage power supply 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 A schematic diagram of the explosion structure. Figure 3 This is an exploded view of the power output component 100 according to an embodiment of the present invention. Figure 4 yes Figure 3 Another structural schematic diagram from another perspective. The energy storage power supply 100 of this application embodiment includes a housing 10, a battery module 30, a voltage conversion circuit, and an output component 20. The housing 10 forms a receiving cavity 13 and an opening 11, and the opening 11 communicates the receiving cavity 13 with the outside. The battery module 30 is disposed in the receiving cavity 13. The voltage conversion circuit is disposed in the receiving cavity 13, electrically connected to the battery module 30, and converts the electrical energy of the battery module 30. The output component 20 is electrically connected to the voltage conversion circuit. The output component 20 includes at least two output ports 221 and an operating member 222. The operating member 222 protrudes from the housing 10, and the output ports 221 are located inside the housing 10. The output ports 221 can move relative to the housing 10 under the action of the operating member 222, so as to drive the output ports 221 to a position aligned with or deviated from the opening 11.

[0036] In the energy storage power supply 100 of this application embodiment, the output port 221 can be moved to a position aligned with or deviated from the opening 11 under the action of the operating member 222. When an external device needs to connect the energy storage power supply 100, the operating member 222 drives the output port 221 to align with the opening 11, thereby realizing the connection between the energy storage power supply 100 and the external device. When the output port 221 is in an idle state, the operating member 222 drives the output port 221 to deviate from the opening 11, thereby making the output port 221 covered by the housing 10, realizing the hiding of the output port 221 in the non-use state.

[0037] Thus, the output port 221 can be exposed or shielded by the operating component 222. The operation is simple and can keep the output port 221 shielded when not in use. This effectively prevents problems such as contact corrosion and accidental short circuits caused by long-term exposure of the output port 221, improves the working safety and reliability of the output port 221, and helps to extend its service life and meet relevant usage requirements.

[0038] Specifically, the output component 20 is a part used to provide power output to external devices. It is a key functional module of the portable energy storage power supply 100, enabling the transfer of power from the energy storage power supply 100 to external loads. It also integrates protection functions to protect the output port 221, providing stable power supply to external electronic devices and improving the reliability and safety of outdoor use. The housing 10 is the external support and protective structure of the energy storage power supply 100, used to house and protect the internal output component 20. It also provides an external output channel for the output port 221 through the opening 11. Its material possesses a certain strength and weather resistance, capable of blocking external dust, moisture, and physical impacts, providing a stable working environment for the internal structure.

[0039] The battery module 30 is housed inside the housing 10 and is responsible for storing a large amount of electrical energy, providing raw power to all power-consuming modules of the energy storage power supply 100. The voltage conversion circuit is located inside the housing 10, with its input terminal electrically connected to the battery module 30. It receives the raw electrical energy output from the battery module 30 and performs voltage boosting / downscaling, AC / DC conversion, voltage stabilization, and current limiting. It can either step down the high-voltage DC output from the battery module 30 to multiple low-voltage DC levels (5V, 10V, 15V, 20V, etc.) to charge external digital devices, or boost the low-voltage DC to high-voltage DC output according to power demand, adapting to the power supply needs of loads with different power ratings and voltage ratings.

[0040] The output component 20 is electrically connected to the output terminal of the voltage conversion circuit, and receives the converted electrical energy and outputs it to the outside. The output component 20 includes at least two different types of output ports 221 and an operating element 222 for manual operation. The end of the operating element 222 extends out of the outer side of the housing 10, allowing the user to directly rotate it manually. All output ports 221 are arranged inside the housing cavity 13 and are not directly exposed to the outside.

[0041] By tossing or rotating the operating component 222, the user can cause the output port 221 to move relative to the housing 10, changing the relative position of the output port 221 and the opening 11 of the housing 10. This allows any one output port 221 to be moved to a position completely aligned with the opening 11, allowing the port to pass through the opening 11 and be exposed for plugging in and drawing power. Alternatively, all output ports 221 can be moved to a position away from the opening 11, so that the housing 10 is directly opposite the opening 11 to seal it off, isolating external dust and moisture, and achieving protection in the idle state. The entire structure relies on the operating component 222 to drive the output port 221 to move, uniformly completing the switching of power supply and idle sealing protection of multiple output ports 221, integrating multiple functions such as energy storage, power voltage regulation, multi-channel controllable output, and safety dust protection.

[0042] In some embodiments, the output component 20 includes a first output component 21 and a second output component 22 disposed within the receiving cavity 13. The first output component 21 is electrically connected to the voltage conversion circuit, and the second output component 22 is movably electrically connected to the first output component 21. An output port 221 and an operating component 222 are disposed on the second output component 22.

[0043] Specifically, the second output component 22 is a functional carrier disposed within the housing 10 and rotatable around the first output component 21. It integrates and drives the output port 221 to move synchronously, and simultaneously receives external operating force in conjunction with the operating component 222 to achieve alignment or offset switching between the output port 221 and the opening 11. The first output component 21 is disposed within the housing 10, serving as the mounting and positioning reference for the second output component 22, providing rotational support for the second output component 22 and limiting its radial and axial displacement, thus ensuring the stability of the second output component 22's movement within the housing 10.

[0044] The second output component 22 has an output port 221 and an operating component 222 spaced apart from the output port 221. The operating component 222 passes through the housing 10, and the output port 221 is located inside the housing 10. The second output component 22 receives external operating force through the operating component 222 and rotates about the center of the first output component 21. The output port 221 can be a USB-A or USB-C interface for external power transmission. When aligned with the opening 11, it can supply power to external devices through the opening 11; when it deviates from the opening 11, it is blocked and protected by the housing 10. In the embodiments of this application, multiple output ports 221 can be provided on the second output component 22. Different output ports 221 can provide different interfaces to meet the connection requirements of external devices using different interfaces.

[0045] The operating component 222 is installed in the housing 10 and serves as the direct component for user operation, transmitting external actions to the second output component 22. Simultaneously, its cooperation with the housing 10 provides a certain degree of dust and water protection. The second output component 22 can move relative to the first output component 21 under the action of the operating component 222, thereby moving the output port 221 to a position aligned with or offset from the opening 11. This allows for switching between two states: exposed power supply and closed protection for the output port 221. The operating component 222 controls the exposure and concealment of the output port 221, providing convenient operation and reliable protection. This effectively avoids the risk of dust and moisture intrusion and accidental short circuits caused by long-term exposure of the output port 221, improving the electrical safety and service life of the product in complex outdoor environments.

[0046] Please see Figure 1 In some embodiments, the operating member 222 can drive the second output member 22 to slide relative to the first output member 21, so that the output port 221 slides to a position aligned with or offset from the opening 11.

[0047] Specifically, the operating component 222 is exposed on the outside of the housing 10 and can be manually operated. The second output component 22 is equipped with various output ports 221 and is slidably mounted on the first output component 21. The operating component 222 is rigidly connected to the second output component 22. When the operating component 222 is turned or pushed or pulled, it can directly drive the second output component 22 to perform linear reciprocating sliding relative to the first output component 21. Throughout the entire sliding stroke of the second output component 22, the second output component 22 always maintains a stable electrical connection with the first output component 21.

[0048] The relative sliding between the two changes the alignment state between the output port 221 and the opening 11 of the housing 10. After sliding into place, the position of the second output component 22 can be locked by the matching locking structure, so that the corresponding output port 221 is aligned with the opening 11 for external power supply. After the locking constraint is released, the reset elastic element 225 drives the second output component 22 to slide and reset in the opposite direction, and the port is synchronously deviated from the opening 11 to achieve closed protection.

[0049] Please see Figure 1 and Figure 2 In some embodiments, the operating member 222 can drive the second output member 22 to rotate relative to the first output member 21, so that the output port 221 rotates to a position aligned with or offset from the opening 11.

[0050] Specifically, the second output component 22 integrates all output ports 221 and is rotatably mounted on one side of the first output component 21. The operating component 222 is fixedly connected to the second output component 22. When the operating component 222 is rotated, it can synchronously drive the second output component 22 to rotate relative to the first output component 21. The relative circumferential rotation of the two is used to adjust the relative position of the output port 221 and the opening 11 of the housing 10. After rotating to the corresponding position, the internal guide limit structure engages and positions, so that the target output port 221 is aligned with the opening 11 and exposed for power supply. After the limit is released, the elastic component 225 pulls the second output component 22 to rotate back and reset, and the output port 221 deviates from the opening 11 to complete the sealing and blocking.

[0051] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the second output element 22 of the output component 20 of the present invention. Figure 6 yes Figure 5 A schematic diagram of the exploded structure. In some embodiments, the second output component 22 includes a male plate 223 and a rotating disk 224. The male plate 223 is electrically connected to the first output component 21 and can rotate relative to the male plate 223. The rotating disk 224 is fixedly connected to the male plate 223, and the output port 221 is disposed on the male plate 223.

[0052] In the above embodiment, the public board 223 is electrically connected to the first output component 21, and the output port 221 is disposed on the public board 223. The power is output from the first output component 21 to the output port 221 through the public board 223, ensuring normal power supply to the output port 221, and the overall structure is relatively compact.

[0053] Specifically, the public board 223 is the core conductive substrate of the second output component 22. It can be integrally formed with an insulating substrate and conductive lines. It can maintain a continuous electrical connection with the first output component 21 while achieving unobstructed relative rotation, providing a stable power supply path for the output port 221. Multiple sets of output ports 221 can be integrated on the public board 223. Each output port 221 is distributed at a set angle and can correspond to different specifications of output terminals such as USB-A interface and USB-C interface.

[0054] The rotating disk 224 has a ring structure and is fixed coaxially with the operating component 222. The rotating disk 224 is provided with a corresponding connection end of the output port 221 to ensure that the output port 221 is stable and has reliable contact after installation. The male plate 223 and the rotating disk 224 can be rigidly fixed by the second fastener 226, such as a screw. The two rotate synchronously. The output port 221 on the male plate 223 switches between different angle positions as the rotating disk 224 rotates, realizing the conversion between exposed power supply and hidden protection.

[0055] Output port 221 is a power output terminal fixed on the public board 223. Its pins are directly connected to the conductive lines on the public board 223 to ensure stable transmission of power supply signals. The end of output port 221 protrudes from the end face of the rotating disk 224. When rotated to the position aligned with the opening 11 of the housing 10, it can be plugged into the plug of an external device through the opening 11 to realize the power supply function. When rotated away from the position of the opening 11, output port 221 is blocked by the housing 10 to avoid direct exposure to the external environment, effectively preventing dust and moisture from entering the contacts. At the same time, it avoids accidental short contact points caused by metal objects such as keys and coins, eliminating the risk of short circuits, overheating and fire, improving the electrical safety and reliability of the product for outdoor use, and greatly improving the service life and user experience of products using the energy storage power supply 100 of this invention in complex outdoor scenarios such as camping and self-driving.

[0056] Please see Figure 5 , Figure 6 and Figure 7 , Figure 7 This is a schematic diagram of the structure of the first output component 21 and a cross-sectional view of the second output component 22 of the present invention. In some embodiments, a conductive part 2231 electrically connected to the output port 221 is provided on the male plate 223. The conductive part 2231 and the output port 221 are respectively provided on opposite sides of the male plate 223. The conductive part 2231 includes a stylus 22311. The first output component 21 is provided with an annular conductive ring 2121. The stylus 22311 contacts the conductive ring 2121.

[0057] In the above embodiments, the first output component 21 and the second output component 22 ensure the electrical connection of the output port 221 in various states through the contact between the conductive ring 2121 and the contact pin 22311. The connection method is simple and highly reliable.

[0058] Specifically, the conductive portion 2231 on the parent board 223 is an electrical contact structure located on the side of the parent board 223 facing away from the output port 221. It is a conductive component that maintains a continuous electrical connection between the parent board 223 and the first output component 21 during rotation. It extends the power supply path of the output port 221 to the back of the parent board 223, forming a slidable contact with the conductive ring 2121 of the first output component 21 via the contact pin 22311. As the parent board 223 rotates with the second output component 22, it maintains electrical continuity between the output port 221 and the internal circuitry of the power supply, preventing power interruption due to rotation.

[0059] The core component of the conductive part 2231 is the contact pin 22311. Multiple contact pins 22311 can be provided on one conductive part 2231. The contact pin 22311 can be a conductive contact with elastic preload, for example, by providing stable contact pressure through an internal spring or elastic sheet structure to ensure reliable contact with the conductive ring 2121 and prevent poor contact or arcing. Of course, the contact pin 22311 can also be in other forms. After the second output component 22 and the first output component 21 are assembled, the contact pin 22311 maintains contact with the conductive ring 2121. The end of the contact pin 22311 can be a spherical or arc-shaped surface, allowing it to slide smoothly on the surface of the conductive ring 2121, reducing friction and wear, and extending its service life.

[0060] The conductive ring 2121 on the first output component 21 is a ring-shaped conductive component. It is a ring-shaped conductive track fixed on the first output component 21 and connected to the internal power supply circuit of the power supply. It provides a 360° uninterrupted continuous conductive contact surface for the contact pin 22311. No matter how the public board 223 is rotated to any angle, the contact pin 22311 can maintain contact with the conductive ring 2121, thereby achieving stable power supply to the output port 221 in all states. The conductive ring 2121 adopts a continuous ring design without breaks or gaps, ensuring that the contact pin 22311 will not lose contact during sliding. Its material can be a wear-resistant and highly conductive metal material, and the surface can be plated with an anti-oxidation coating to improve contact stability and corrosion resistance.

[0061] For example, the number of conductive coils 2121 is the same as the number of styluses 22311 on each conductive part 2231, and different styluses 22311 on the conductive part 2231 correspond to different conductive coils 2121.

[0062] The pins of the output port 221 are electrically connected to the contact pins 22311 of the conductive part 2231 to realize cross-side transmission of power supply signals. The conductive part 2231 and the output port 221 are respectively located on opposite sides of the public board 223, so that the output port 221 is arranged facing the opening 11 of the housing 10 to realize external insertion, and the conductive part 2231 is arranged facing the first output member 21 to realize contact with the conductive ring 2121. This not only ensures the insertion space of the output port 221, but also provides a reliable installation position for the rotary electrical connection. Through the cooperation of the contact pins 22311 and the conductive ring 2121, the electrical connection problem of the second output member 22 in the dynamic switching state is solved, and a stable power supply foundation is provided for the exposed power supply and hidden protection of the output port 221.

[0063] Please see Figure 2 and Figure 5In some embodiments, the rotating disk 224 is provided with a blocking part 2241 protruding toward the side where the operating member 222 is located. The blocking part 2241 and the output port 221 are arranged around the rotation center of the second output member 22. The blocking part 2241 is used to block the opening 11.

[0064] In the above embodiment, the blocking part 2241 is rotated to a position aligned with the opening 11 to block the opening 11. The blocking operation is simple and convenient. The blocking part 2241 and the output port 221 are integrated on the rotating disk 224, making the overall structure more compact.

[0065] Specifically, the shielding part 2241 on the rotating disk 224 is a block-shaped protrusion structure protruding towards the side of the operating member 222. It is arranged around the rotation center of the second output member 22 together with the output port 221. When the output port 221 rotates with the second output member 22 to a position away from the opening 11, the shielding part 2241 moves to a position directly opposite the opening 11, completely shielding the opening 11 on the housing 10, forming a physical barrier to prevent external dust, water vapor, mud and other impurities from entering the interior of the housing 10 through the opening 11. At the same time, it prevents metal conductive objects from contacting the metal contacts of the output port 221 through the opening 11, eliminating electrical safety hazards such as short circuits, overheating and even fire.

[0066] The shielding part 2241 and the output port 221 are arranged in a ring shape and share the same rotation center. This allows the output port 221 and the shielding part 2241 to alternately align with the opening 11 in different positions of the second output member 22. That is, when the output port 221 is aligned with the opening 11, the shielding part 2241 is in an off-center position, which does not affect the plugging operation of the external device electrical connection. When the shielding part 2241 is aligned with the opening 11, the output port 221 is shielded by the inner wall of the housing 10 and is in a protected state. There is no need to set up an additional independent protective cover. The working and protective states of the interface can be switched synchronously by the rotation of the second output member 22. The structure is compact and easy to operate, which effectively improves the protective performance and electrical safety of the product in complex outdoor environments.

[0067] Please see Figure 2 , Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the structure of the first output element 21 of the output component 20 according to an embodiment of the present invention. Figure 9 yes Figure 8A schematic diagram of the exploded structure. In some embodiments, the first output component 21 includes a fixed disk 211 and a mother plate 212. The fixed disk 211 is fixed inside the housing 10. The mother plate 212 and the fixed plate 31 are fixedly connected. The mother plate 212 is provided with a conductive ring 2121 that is electrically connected to the output port 221. A limiting member 213 is installed on the fixed disk 211. The limiting member 213 is used to limit the rotation position of the second output component 22 when it abuts against the second output component 22, so that the output port 221 is exposed through the opening 11.

[0068] In the above embodiment, the rotation position of the second output component 22 is limited by the small limiting component 213 installed on the fixed plate 211, ensuring that the output port 221 can be stably maintained in a position aligned with or deviated from the opening 11, ensuring a stable connection between the output port 221 and the external device and the long-term effectiveness of the protection state.

[0069] Specifically, the fixed disk 211 is the annular support base of the first output component 21. It is an annular component installed inside the housing 10, providing a fixed reference for the mother plate 212 and the limiting component 213. It provides installation positioning for the entire first output component 21 and provides an installation position for the limiting component 213. Through the fixed connection with the inside of the housing 10, it ensures the stability of the position of the first output component 21 inside the housing 10, and provides a stable rotation center for the rotation of the second output component 22, so that the second output component 22 can rotate smoothly around its center.

[0070] The mother plate 212 is the conductive base of the first output component 21. It is a conductive component that is fixedly connected to the fixed disk 211 and is used to provide continuous power supply to the output port 221. The mother plate 212 carries the annular conductive ring 2121 and is connected to the power supply circuit through internal wiring. During the rotation of the second output component 22, it always maintains electrical connection with the output port 221 to achieve uninterrupted power supply.

[0071] The limiting component 213 is a rigid positioning component installed on the fixed plate 211. It is a stop structure that cooperates with the relevant groove on the second output component 22 to realize the positioning of the second output component 22. When the second output component 22 rotates to a preset angle where the output port 221 is aligned with the opening 11, it engages or abuts with the relevant track groove of the second output component 22, restricting the second output component 22 from continuing to rotate, so that the output port 221 is stably stopped at the position aligned with the opening 11, realizing the precise positioning of the second output component 22, ensuring that the output port 221 can be accurately aligned with the opening 11, avoiding the insertion failure caused by excessive rotation or incomplete positioning, and providing clear position feedback to the user, improving the operating feel and ease of use.

[0072] The mother plate 212 and the fixed plate 211 can be fixed together by the first fastener 214. The fixed plate 211, the mother plate 212 and the limiting member 213 work together to form the core structure of the first output member 21. The fixed plate 211 provides installation support, the mother plate 212 provides a conductive path, and the limiting member 213 realizes the positioning of the output port 221. This not only ensures the power supply stability during the rotation of the second output member 22, but also realizes the precise control of the position of the output port 221, providing a reliable structural foundation for the exposed power supply and hidden protection of the output port 221.

[0073] Please see Figure 6 and Figure 9 In some embodiments, the limiting member 213 includes a positioning post 2131 and a body 2132 rotatably connected to the positioning post 2131. The positioning post 2131 is fixed to the fixed plate 211, and the body 2132 is provided with a connecting post 2133, which is used for the second output member 22 to abut.

[0074] In the above embodiment, the limiting member 213 abuts against the second output member 22 through the connecting post 2133 to restrict the rotation of the second output member 22. The limiting method is simple, the movement form is intuitive, and the overall structure of the limiting member 213 is compact, which is conducive to further improving the structural compactness.

[0075] Specifically, the positioning post 2131 of the limiting member 213 is a rigid columnar component, fixed to the preset installation position of the fixed plate 211, providing a rotation fulcrum for the body 2132 of the limiting member 213, allowing the body 2132 to rotate freely around the positioning post 2131 at a small angle. The setting of the positioning post 2131 ensures the stability of the installation position of the limiting member 213 and provides reliable axial support for the rotation of the body 2132. The body 2132 is a movable component adapted to the trajectory groove of the second output member 22. One end of it is hinged to the positioning post 2131 and can rotate around the positioning post 2131, while the other end is provided with a connecting post 2133, which serves as the force-bearing part that directly abuts against the second output member 22.

[0076] When the second output component 22 rotates with the operating component 222, the connecting post 2133 can slide along the guide groove 2242 of the second output component 22. When the main body 2132 is about to reach the preset position, it rotates at a small angle and when it reaches the preset position, the connecting post 2133 is inserted into the groove to form a mechanical stop, which restricts the second output component 22 from continuing to rotate, so that the output port 221 is stably stopped in the working position aligned with the opening 11, and the position of the output port 221 is accurately positioned. When the second output component 22 is reset in the reverse direction, the external force makes the main body 2132 rotate around the positioning post 2131 in the opposite direction to avoid it, so that the connecting post 2133 can slide out of the groove smoothly and avoid jamming or stuck.

[0077] Meanwhile, the rotation angle of the main body 2132 matches the contour of the guide rail groove 2242 and other structures of the second output component 22, ensuring smooth and unobstructed limiting and resetting actions. This not only ensures the stable positioning of the second output component 22 in the working position of the output port 221, preventing the output port 221 from shifting and causing plug-in failure, but also provides clearance for the automatic resetting of the second output component 22, allowing the second output component 22 to smoothly return to the initial protective position. This achieves dual protection of limiting positioning and smooth resetting, improving the product's operating feel and structural reliability.

[0078] Please see Figure 10 and Figure 11 , Figure 10 yes Figure 8 Structural plan, Figure 11 yes Figure 10 The enlarged view of the structure at point A. In some embodiments, the rotating disk 224 has a guide groove 2242, in which a plurality of first guide blocks 2243 and a plurality of second guide blocks 2244 are provided. The first guide blocks 2243 and the second guide blocks 2244 are alternately spaced along the circumference of the rotating disk 224. The first guide blocks 2243, the second guide blocks 2244 and the rotating disk 224 together define a guide groove 2245 for the connecting post 2133 to slide along the first circumference. The connecting post 2133 slides along the guide groove 2245 and abuts against one of the first guide blocks 2243 to limit the rotational position of the second output member 22.

[0079] In the above embodiment, the position of the output port 221 is maintained by the contact between the end face of the first guide block 2243 and the connecting post 2133, and the movement trajectory of the connecting post 2133 is restricted by the guide groove 2242, so as to ensure the rotational smoothness of the second output component 22 relative to the first output component 21 and the reliability of the position maintenance of the second output component 22, thereby meeting the user's need for rapid operation.

[0080] Specifically, the guide groove 2242 is an annular groove opened along the circumference on the rotating disk 224. Its contour is adapted to the rotation trajectory of the second output component 22. It provides a preset sliding track for the connecting column 2133 of the limiting component 213. It is the basic carrier for guiding and limiting. The groove wall and groove bottom are smoothed to reduce the frictional resistance when the connecting column 2133 slides, ensuring smooth movement.

[0081] The first guide block 2243 and the second guide block 2244 are protrusions that are alternately distributed circumferentially within the guide rail groove 2242. Together, they define a guide groove 2245 whose width matches the diameter of the connecting post 2133. This not only constrains the sliding path of the connecting post 2133 and prevents it from moving radially, but also forms a continuous guide trajectory through the alternating arrangement.

[0082] The first guide block 2243 acts as a stop component. When the connecting column 2133 slides along the guide groove 2245 to the position of the first guide block 2243, it will be blocked by the end face of the first guide block 2243, forming a mechanical stop and restricting the second output component 22 from continuing to rotate. At this time, the output port 221 on the second output component 22 is exactly aligned with the opening 11 of the housing 10, realizing the precise positioning of the working position of the output port 221. The front inclined surface of the first guide block 2243 can guide the connecting column 2133 to slide smoothly into the locking position, avoiding jamming or sticking, and ensuring smooth operation.

[0083] The second guide block 2244 serves as an auxiliary guide component, used to constrain the sliding direction of the connecting column 2133, ensuring that it always moves along the preset path. At the same time, it works with the first guide block 2243 to form a continuous guide groove, preventing the connecting column 2133 from derailing during the sliding process.

[0084] Figure 10 In the diagram, the dashed line with arrows represents the movement trajectory of the connecting column 2133 relative to the guide rail groove 2242 of the rotating disk 224, and the direction of the arrows indicates its movement direction relative to the guide rail groove 2242. When the operating component 222 drives the second output component 22 along the first circumferential direction ( Figure 10 When rotating clockwise, the connecting column 2133 slides along a preset trajectory under the constraint of the guide groove 2245, and the second guide block 2244 continuously guides its movement direction. When it reaches the stop position of a first guide block 2243, or is between the stop position of a first guide block 2243 and the stop position of the next first guide block 2243, the force acting on the operating member 222 can be released.

[0085] The operating member 222 is connected to the elastic member 225. During the operation of the operating member 222, the elastic member 225 undergoes elastic deformation under the action of the operating member 222 and generates a force in the opposite direction. This force in the opposite direction may include a force that causes the second output member 22 to reverse and a force that causes the connecting post 2133 to move closer to the center of the second output member 22. When the connecting post 2133 reaches the stop position of a first guide block 2243, the force acting on the operating member 222 is released. The operating member 222 rotates in the opposite direction under the action of the elastic member 225. Consequently, the connecting post 2133 rotates in the opposite direction relative to the second output member 22 and abuts against the limiting end face of the first guide block 2243 under the action of the elastic member 225. The second output member 22 is restricted from rotating, and the output port 221 is stably stopped in the exposed position aligned with the opening 11, realizing the position switching of different interfaces.

[0086] The cooperation of the guide rail groove 2242, the first guide block 2243, the second guide block 2244 and the connecting post 2133 not only achieves smooth guidance during the rotation of the second output component 22, but also ensures the accurate positioning of the interface position of the output port 221 through the stop function of the first guide block 2243, ensuring the stability and reliability of the interface position of the output port 221 during the plug-in operation. At the same time, the inclined surface design of the first guide block 2243 and the second guide block 2244 also reduces the operating resistance and improves the smoothness of the position switching of the output port 221 and the user experience.

[0087] In some embodiments, the guide groove 2245 includes a first guide section 22451 and a second guide section 22452. The first guide section 22451 is formed on the side of the first guide block 2243 and the second guide block 2244 facing the center of the rotating disk 224. The second guide section 22452 is formed on the side of the first guide section 22451 away from the center of the rotating disk 224. Both ends of the second guide section 22452 are connected to the first guide section 22451. The connecting post 2133 can slide from one end of the first guide section 22451 along the first guide section 22451 to the other end of the first guide section 22451 to abut against one of the first guide blocks 2243.

[0088] In the above embodiment, when the connecting post 2133 moves along the second guide section 22452 to the first guide section 22451, it can smoothly abut against the first guide block 2243 under the action of the first guide section 22451. Through the cooperation of the first guide section 22451 and the second guide section 22452, the movement trajectory of the connecting post 2133 is stabilized, and the position of the output port 221 is kept stable.

[0089] Specifically, the second guide section 22452 is formed in the inner area of ​​the first guide block 2243 and the second guide block 2244 near the center of the rotating disk 224. The first guide section 22451 is arranged on the radially outward side of the second guide section 22452. The first and last ends of the first guide section 22451 are respectively connected to the two adjacent second guide sections 22452. The guide groove 2245 forms a closed-loop sliding passage with internal and external connections. The groove width matches the outer diameter of the connecting column 2133, which restricts the radial movement of the connecting column 2133 and prevents it from falling off the track.

[0090] When the button is rotated clockwise, the operating component 222 drives the rotating disk 224 to rotate clockwise. The connecting column 2133 enters the outer first guide section 22451 from one end of the first guide section 22451 and slides circumferentially along the first guide section 22451 to the end. Under the guidance of the arc surfaces at both ends, it is embedded in the slot and abuts against the end face of the first guide block 2243. The position of the rotating disk 224 is locked by mechanical abutment. The USB-A or USB-C interface of the corresponding output port 221 is aligned with the opening 11 of the housing 10 and exposed. During this process, the rotating disk 224 twists the elastic element 225 to accumulate rebound potential energy.

[0091] When the button is rotated to the next second guide segment 22452, the connecting post 2133 slides out from the limiting end of the first guide block 2243 and releases the force of the operating member 222. The elastic member 225 releases energy and pulls the rotating disk 224 to rotate in the opposite direction. The connecting post 2133 is no longer limited by the first guide block 2243. The connecting post 2133 disengages from the end of the first guide segment 22451 and rotates into the inner second guide segment 22452. It then slides counterclockwise along the second guide segment 22452 back to the starting position, completing the reset. The shielding part 2241 seals the opening 11 of the housing 10.

[0092] Please see Figure 10 and Figure 11 In some embodiments, the first guide block 2243 has a first guide arc surface 22431 opposite to the first end of the second guide block 2244. The first guide arc surface 22431 is offset away from the center of the rotating disk 224 along the first circumferential direction, and the first guide arc surface 22431 forms the side of the second guide segment 22452. The second end of the second guide block 2244 has a second guide arc surface 22441 opposite to the first guide block 2243. The second guide arc surface 22441 forms the side of the second guide segment 22452. The second guide arc surface 22441 is offset towards the center of the rotating disk 224 along the first circumferential direction. The connecting post 2133 can be inserted into the gap between the second guide arc surface 22441 and the first guide block 2243 during sliding to abut against the first guide block 2243.

[0093] In the above embodiment, through the cooperation of the first guide arc surface 22431 and the second guide arc surface 22441, the connecting post 2133 is smoothly moved in the guide groove 2245, ensuring that the connecting post 2133 is smoothly locked by the first guide block 2243 after reaching the predetermined position, thus providing a guarantee for the stable power supply of the output port 221.

[0094] Specifically, the first guide block 2243 and the second guide block 2244 are arranged in a matching manner in the guide rail groove 2242. The first guide arc surface 22431 of the first guide block 2243 is deflected away from the center of the rotating disk 224 along the first circumferential direction, while the second guide arc surface 22441 at the first end of the second guide block 2244 is deflected in the same direction towards the center of the rotating disk 224. Together, they form a wedge-shaped guide channel that gradually widens at the entrance and narrows at the end. The gap size at the end of the channel is adapted to the diameter of the connecting column 2133.

[0095] When the connecting post 2133 slides along the guide groove 2245, it first contacts the second guide arc surface 22441. The second guide arc surface 22441 guides the connecting post 2133 to deflect away from the center of the rotating disk 224 through a smooth curve contour. Then the connecting post 2133 enters the working area of ​​the first guide arc surface 22431. The first guide arc surface 22431 guides the connecting post 2133 away from the center with an outwardly sloping curve, so that the connecting post 2133 slides precisely into the gap between the second guide arc surface 22441 and the first guide block 2243. Finally, it is mechanically stopped by the end face of the first guide block 2243, which restricts the second output component 22 from continuing to rotate.

[0096] Thus, through the combined action of the first guide arc surface 22431 and the second guide arc surface 22441, the smooth insertion and precise positioning of the connecting post 2133 are achieved. The first guide arc surface 22431 and the second guide arc surface 22441 eliminate the impact and jamming of the right-angle step stop, reduce the operating resistance when the operating component 222 rotates, and the two work together to ensure that after the connecting post 2133 moves relative to the second guide block 2244, it accurately enters the trajectory defined by the first guide block 2243, and finally slides into the end limit position of the first guide block 2243, ensuring that the connecting post 2133 can be stably locked into the stop position every time, so that the second output component 22 accurately stops at the preset angle, ensuring the alignment accuracy of the output port 221 and the opening 11 of the housing 10, and improving the plug-in reliability and wear resistance of the structure in the exposed state of the output port 221 interface.

[0097] Please see Figure 10 and Figure 12 , Figure 12 This is a partial structural cross-sectional view of the output component 20 of the present invention. In some embodiments, the output component 20 further includes an elastic element 225, which connects the housing 10 and the rotating disk 224. The elastic element 225 is used to elastically deform when the rotating disk 224 rotates along a first circumferential direction, and to recover its deformation when the connecting post 2133 disengages from the first guide block 2243, so that the connecting post 2133 rotates along the first guide segment 22451 along a second circumferential direction, and drives the rotating disk 224 and the operating member 222 to rotate and reset along the second circumferential direction.

[0098] In the above embodiment, the second output component 22 is reset by the elastic element 225. The elastic element 225 can store force when the operating component 222 is rotated by external force, and release the elastic force after the connecting column 2133 is disengaged from the snap-fit ​​position, thereby resetting the second output component 22 and making the opening 11 blocked by the blocking part 2241. No additional reset mechanism is required, and the operation is simple and the cost is low.

[0099] Specifically, the guide rail groove 2242 is formed by the first guide block 2243, the second guide block 2244, and the rotating disk 224, which together enclose the first guide section 22451 and the second guide section 22452. The first guide section 22451 and the second guide section 22452 are interconnected radially along the rotating disk 224, forming a bidirectional sliding path. The second guide section 22452 allows the connecting column 2133 to slide along the second circumferential direction. Figure 10 Slide freely in the counterclockwise direction.

[0100] The elastic element 225 is an energy storage and reset component, specifically a spring. Its two ends are connected to the housing 10 and the rotating disk 224 respectively. The housing 10 is provided with a locking interface 12 at the position where it connects to the operating element 222. One end of the elastic element 225 is inserted into the locking interface 12 to fix one end and to generate elastic deformation under the combined action of the operating element 222 and the locking interface 12.

[0101] When the operating component 222 drives the rotating disk 224 to rotate in the first circumferential direction, and the connecting column 2133 slides in the guide groove 2245 and engages with the end of the first guide block 2243, the rotating disk 224 simultaneously pulls the elastic component 225, causing it to undergo elastic deformation, and mechanical energy is converted into elastic potential energy to complete energy storage. After the external force is removed, the elastic component 225 drives the connecting column 2133 to move towards the center of the second output component 22 and engages with the end of the first guide block 2243 under the elastic force of the elastic component 225. The second output component 22 and the first guide block 2243 are in close contact, thereby achieving their holding in the corresponding position.

[0102] When the external force is removed, and the connecting post 2133 is not held in place by the first guide block 2243, the connecting post 2133 disengages from the contact limit with the first guide block 2243. The elastic element 225 is no longer constrained, and the stored elastic potential energy can be quickly released and restored to its original state, providing a rebound force to pull the rotating disk 224 and the operating element 222 to rotate as a whole along the second circumferential direction. The connecting post 2133 then moves smoothly back along the connected second guide section 22452 until the second output element 22 returns to its initial position, completing the overall reset action. Exemplarily, the operating element 222, the elastic element 225, the rotating disk 224, and the male plate 223 are fixed by the second fastener 226 to ensure the stability of the relative positions of each part.

[0103] The overall structure of the second output component 22 relies on the interconnected first guide section 22451 and second guide section 22452 to distinguish between two motion trajectories: forward engagement and reverse reset. The paths do not interfere with each other, and the sliding process is smooth and without jamming. The elastic element 225 serves as the power source to achieve automatic reset of the second output component 22, eliminating the need for manual retraction of the operating element 222. This simplifies the operation process and ensures that the second output component 22 can return to the protective position in a timely manner after use, allowing the shielding part 2241 to seal the opening 11 of the housing 10, thus balancing the smoothness of structural movement with the protective effect of the equipment.

[0104] The energy storage power supply 100 is composed of a battery module 30 and the aforementioned power output component 100. The battery module 30 is assembled inside the housing 10, responsible for storing electrical energy and continuously supplying power to the power output component 100. The housing 10 also provides unified encapsulation and protection for the battery module 30 and the output component, preventing damage to the components from external impacts, moisture, and dust. A fixing plate 31 is fixedly installed on the battery module 30, and the first output component 21 is fixed to the battery module 30 through the fixing plate 31 to ensure a stable connection between it and the battery module 30.

[0105] Output port 221 is fixed and its posture is limited by operating component 222. The internal second output component 22, limiting structure, and conductive contact structure work together to achieve position switching, power supply, and idle protection for various interfaces. During operation, the operator can rotate operating component 222 to drive the second output component 22 to switch positions. The limiting component 213 precisely stops it in the corresponding position, so that the designated output port 221 interface is exposed and can supply power normally. When the limiting is released, the elastic component 225 releases elastic potential energy, causing the second output component 22 and operating component 222 to automatically rotate back to reset. The shielding part 2241 simultaneously closes the opening 11 of the housing 10, and the output port 221 interface enters the hidden protection state.

[0106] The energy storage power supply 100 integrates its energy storage unit with the controllable output component 20 into one unit. The structure is compact and takes into account multiple functions such as energy storage, multiple outputs, output port 221 switching, automatic reset and safety protection. The overall operation is stable and it is suitable for a variety of usage scenarios.
