Description

Technical Field

[0001] The invention relates to the technical field of battery packs, in particular to a portable multifunctional household energy storage power supply. Background Art

[0002] Energy storage power supply is a device that converts and stores electrical energy. After energy storage, the energy storage power supply can flexibly supply power at any time, bringing convenience to people's electricity life. At present, the commonly used storage method is chemical energy storage, that is, using battery packs to store electricity. This method has good use effect due to its fast response speed and high energy density. In order to increase the stored energy, energy storage power supplies are usually equipped with multiple groups of batteries, and the positive and negative poles of these batteries need to be correctly connected to form a complete circuit. In addition, the use of non-integrated battery design is also for easy repair. Once a part is damaged, it can be repaired without removing the entire energy storage power supply.

[0003] Observing the characteristics of current energy storage power supplies, we find that these battery packs can be designed as assembled types.

[0053] See also Figure 1 , Figure 2 and Fig.10 , and also includes: rotating a photovoltaic panel 26 installed on the top of the connector 3 on the upper layer, the photovoltaic panel 26 is used to convert electrical energy, and the photovoltaic panel 26 is provided with a triple folding surface, so that the photovoltaic panel 26 can be easily folded and unfolded.

[0054] The working principle of this energy storage power supply is as follows:

[0055] After the energy storage power supply is charged, the product that needs electricity is connected to the connector 3, and the electric energy stored in the energy storage power supply can be used; assuming that when the user uses the energy storage power supply, there is no need to use so many battery packs 5, and wants to reduce the weight by reducing the use of battery packs 5, or when one of the battery packs 5 is damaged and needs to be disassembled for repair:

[0056] First, pull the connecting frame 4 to drive the upper connector 3 to move upward and limit it through the wedge-shaped stopper 14, so that the spacing between the connectors 3 can be increased, providing space for the extraction and release of the battery pack 5, and reducing the friction between the battery packs 5; then operate the motor 13 to start, control the worm 12 to rotate forward, and the rotating worm 12 will control the rotating sliding rod 16 through the transmission function between the worm gear 15 and the transmission cooperation between the worm gear 15 and the fork tooth plate 17. The rotating sliding rod 16 controls the connector 9 to move to the right through the thread 18, and pulls the connector 9 out from the battery pack 5 and the connector 3, that is, synchronously and quickly disconnects all the connectors 3 from the battery pack 5, and now the target battery pack 5 to be removed can be moved forward.

[0057] After the battery pack 5 is taken out, the wedge-shaped stopper 14 is pulled to stop the wedge-shaped stopper 14 from limiting the connection frame 4, and the upper connector 3 is moved downward, and the motor 13 is controlled to start. At this time, the worm 12 is controlled to reverse, and the connector 9 is controlled to move to the left and inserted between the battery pack 5 and the connector 3, so that the positive and negative poles of each battery pack 5 and the connector 3 are reconnected, that is, the energy storage power supply can be used with fewer battery packs 5; in particular, due to the reduction in the number of battery packs 5, the distance moved downward by the upper connector 3 will be longer than the previous upward distance, that is, when the connector 9 is fully inserted into the battery pack 5 and the connector 3, the upper connector 3 is still on the way, that is, the worm wheel 15 is still being driven to rotate, and at this time, the relative displacement between the sliding rod 16 and the connector 9 will cause the sliding rod 16 to slide relative to the bracket 8 due to the stationary state of the connector 9, so that the fork tooth plate 17 is disengaged from the worm wheel 15, and the spring a 19 is stretched, so that the sliding rod 16 will no longer be rotated by the worm wheel 15 and the worm 12, thereby preventing the connector 9 from being affected.

[0058] When the worm gear 15 stops rotating, the spring a19 will reset the relative position between the sliding rod 16 and the worm gear 15 so that the fork tooth plate 17 can cooperate with the worm gear 15 again. In this way, when the worm gear 15 rotates again, the sliding rod 16 can be used to control the connector 9 to be pulled out of the battery pack 5 and the connector 3. When the connector 9 moves to abut against the bracket 8 and can no longer move, the sliding rod 16 slides relative to the bracket 8 again. At this time, the spring a19 is compressed, so that the connector 9 is out of control again. In this way, when the worm 12 controls the movement of the connector 9 and controls the upper connector 3, the two can be adaptively adjusted automatically to ensure the smooth operation of the energy storage power supply and optimize the setting and use of the energy storage power supply.

[0059] When controlling the movement of the upper connector 3, the top block 24 will control the moving plate 20 to move up and down through the triangular block 25: when the connector 3 moves upward and separates from the battery pack 5, the top block 24 will disengage from the triangular block 25, the spring b21 will recover and control the moving plate 20 to move upward, disengaging all the plug blocks 22 from the buckles 23, and releasing the fixation of the battery pack 5; and when the connector 3 moves downward and moves above the battery pack 5, the top block 24 will control the moving plate 20 to move downward through the triangular block 25, the spring b21 will be stretched, thereby inserting the plug blocks 22 into the buckles 23, fixing the battery pack 5, and thus improving the loading stability of the battery pack 5.

[0060] The photovoltaic panel 26 is used to increase the charging mode of the energy storage power supply, and the photovoltaic panel 26 is set to be foldable. While increasing the conversion amount of the photovoltaic panel 26, the occupied area of ​​the photovoltaic panel 26 is reduced, thereby improving the use effect of the photovoltaic panel 26.
