Description

Technical Field

[0001] This invention relates to the field of battery pack technology, specifically to a swappable multifunctional household energy storage power supply. Background Technology

[0002] Energy storage power supplies are devices that convert and store electrical energy. Once stored, they can provide power flexibly at any time, bringing convenience to people's electricity consumption. Currently, the most common storage method is chemical energy storage, which uses battery packs for energy storage. This method is effective due to its fast response speed and high energy density. To maximize the stored energy, energy storage power supplies typically use multiple battery packs, and these batteries need to be correctly connected at their positive and negative terminals to form a complete circuit. Furthermore, the use of a non-integrated battery design facilitates repair; if one part fails, repair can be performed without dismantling the entire energy storage power supply.

[0003] Observing the characteristics of current energy storage power sources, we find that these battery packs can be designed as modular units. When using energy storage power sources, users can increase or decrease the number of battery packs according to actual needs. This allows for more flexible use of energy storage power sources and also allows for the removal of a battery pack if it malfunctions, without affecting the normal operation of other battery packs.

[0004] If the above design is adopted, the connection between the battery packs needs to be designed to be detachable so that the battery packs can be freely removed and placed. However, this will increase the inconvenience when using the energy storage power source, and the positive and negative terminals of the battery packs need to be connected accurately, otherwise it is easy to damage the battery packs or even cause harm to the user.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example: See Figures 1-3 The device includes: a base 1 with casters at the bottom for easy movement and user convenience; a frame 2 fixedly mounted on the base 1 with a handrail at the rear; two connectors 3 on the base 1, the lower connector 3 being fixedly mounted on the base 1; a connecting bracket 4 fixedly mounted on the upper connector 3, slidingly mounted to the frame 2, with the upper connector 3 slidingly mounted on the frame 2 via the connecting bracket 4; three battery packs 5 positioned between the two connectors 3, with the number of battery packs 5 adjustable to change the number used by the device; a connecting wire 6 fixedly mounted between the two connectors 3, connecting one pair of positive and negative terminals of each connector 3; a mounting plate 7 fixedly mounted on the base 1; and four docking components on the mounting plate 7 for connecting the positive and negative terminals of adjacent battery packs 5 or adjacent connectors 3 and battery packs 5.

[0048] See Figure 3The docking assembly includes: a bracket 8 fixedly mounted on the mounting plate 7, with two ring frames on each bracket 8; and a connector 9 slidably mounted on the two ring frames of each bracket 8. The connector 9 is electrically connected to the battery pack 5 / connector 3, and the two connectors 9 on the same bracket 8 are electrically connected to each other. Therefore, the docking assembly can connect the positive and negative terminals of the battery pack 5 / connector 3 it is connected to. At the same time, the position of the bracket 8 is fixed, which can prevent the connector 9 from making mistakes when docking the positive and negative terminals.

[0049] See Figure 1 , Figure 2 and Figure 5 It also includes: a worm gear 12 rotatably mounted on the frame 2; a motor 13 fixedly mounted on the frame 2, with the output end of the motor 13 fixed to the worm gear 12; a wedge-shaped stop 14 slidably mounted on the frame 2, the wedge-shaped stop 14 engaging with the connecting frame 4, and a return spring between the wedge-shaped stop 14 and the frame 2. When the connecting frame 4 is pulled to move the upper connector 3 upward, after the connecting frame 4 contacts the inclined surface of the wedge-shaped stop 14, it can squeeze the wedge-shaped stop 14 to move, allowing the connecting frame 4 to pass over the wedge-shaped stop 14. Subsequently, the wedge-shaped stop 14 can limit the connecting frame 4, preventing the upper connector 3 from falling, thereby changing the distance between the two connectors 3 so that the battery pack 5 can be picked up and put down; and a connecting component set on each docking assembly. The connecting component is used to engage with the worm gear 12 so that the forward and reverse rotation of the worm gear 12 can synchronously control the forward and reverse movement of all connectors 9, realizing the insertion and removal operation of the connectors 9 on the connectors 3 / battery pack 5.

[0050] See Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The connecting components include: a worm gear 15 rotatably mounted on each ring of each bracket 8, the worm gear 15 meshing with a worm 12, the forward and reverse rotation of the worm 12 driving the worm gear 15 to rotate in the same direction; a sliding rod 16 fitted on each ring of the bracket 8, the sliding rod 16 being able to rotate and slide relative to the bracket 8; and a fork-tooth disc 17 fixedly mounted on the end of the sliding rod 16, the fork-tooth disc 17 being inserted into the worm gear 15 so that the sliding rod 16 can be rotated by the worm gear 15, and when the fork-tooth disc 17 disengages from the worm gear 15... When the transmission relationship is released, the sliding rod 16 is provided with a thread 18, and the sliding rod 16 will be threaded to the connector 9 through the thread 18. When the sliding rod 16 rotates relative to the bracket 8, the sliding rod 16 will drive the connector 9 to move. A spring a19 is sleeved on the sliding rod 16, and a ring is rotatably installed in the worm gear 15. The two ends of the spring a19 are fixed to the sliding rod 16 and the ring of the worm gear 15 respectively. The spring a19 is used to reset the relative position between the sliding rod 16 and the worm gear 15.

[0051] See Figure 4 It also includes: a sliding groove 10 is provided on the connector 3 below and the top of each battery pack 5; a sliding plate 11 is fixedly installed on the bottom of each battery pack 5, and the sliding plate 11 can slide into the sliding groove 10 so that each connector 3 and battery pack 5 can be stably connected together, thereby improving the connection stability and safety of this energy storage power supply.

[0052] See Figure 2 , Figure 8 and Figure 9 It also includes: a fixing component set on the base 1 for fixing the positions of each battery pack 5, the fixing component including: a movable plate 20 slidably installed at the rear of the frame 2; a spring b21 fixedly installed between the movable plate 20 and the frame 2, the spring b21 being used to reset the position of the movable plate 20; three inserts 22 fixedly installed on the movable plate 20, the positions of which correspond to the positions of each battery pack 5; a buckle 23 fixedly installed at the rear of each battery pack 5, the movable plate 20 moving up and down can insert the insert 22 into the buckle 23 and pull the insert 22 out of the buckle 23; a top block 24 fixedly installed on the upper connector 3; and a triangular block 25 fixedly installed on the movable plate 20, when the upper connector 3 moves, the top block 24 will contact and engage with the triangular block 25, thereby controlling the movement of the movable plate 20.

[0053] See Figure 1 , Figure 2 and Figure 10 It also includes a photovoltaic panel 26 that is rotatably mounted on top of the connector 3 on the upper layer. The photovoltaic panel 26 is used to convert electrical energy. The photovoltaic panel 26 is provided with a triple fold surface so that the photovoltaic panel 26 can be easily retracted and extended.

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

[0055] After this energy storage power supply is charged, connect the product that needs power to connector 3 to use the electrical energy stored in this energy storage power supply; assuming that the user does not need to use so many battery packs 5 when using this energy storage power supply, and wants to reduce the weight by reducing the number of battery packs 5 used, or if one of the battery packs 5 is damaged and needs to be disassembled for repair:

[0056] First, pull the connecting bracket 4 to move the upper connector 3 upward and limit it by the wedge-shaped stop 14. This increases the spacing between the connectors 3, providing space for the extraction and removal of the battery pack 5, and reducing the friction between the battery packs 5. Then, start the motor 13 to control the worm gear 12 to rotate forward. The rotating worm gear 12 will control the rotating sliding rod 16 through the transmission function between the worm gear 15 and the worm gear 15 and the fork tooth disk 17. The rotating sliding rod 16 will control the connector 9 to move to the right through the thread 18, pulling the connector 9 out of the battery pack 5 and the connector 3. That is, the connection between all connectors 3 and battery pack 5 is disconnected simultaneously and quickly. At this time, the target battery pack 5 to be removed can be moved forward.

[0057] After removing battery pack 5, pull the wedge block 14 to stop it from limiting the connection frame 4, move the upper connector 3 downward, and then start the motor 13. At this time, control the worm gear 12 to reverse, and control the connector 9 to move to the left and insert it between battery pack 5 and connector 3, so that the positive and negative terminals of each battery pack 5 and connector 3 are reconnected, that is, the energy storage power can be used with fewer battery packs 5. In particular, due to the reduction in the number of battery packs 5, the distance that the upper connector 3 moves downward will be longer than the distance that it moved upward before. That is, after the connector 9 is fully inserted into the battery pack 5 and connector 3, the upper connector 3 is still moving. That is, the worm gear 15 is still being driven to rotate. 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 gear 15, and the spring a 19 is stretched. Therefore, the sliding rod 16 will no longer be rotated by the worm gear 15 and 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 17 can re-engage with the worm gear 15. In this way, when the worm gear 15 rotates again, the sliding rod 16 can control the connector 9 to be pulled out from the battery pack 5 and the connector 3. When the connector 9 moves to the point of abutting 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 disengaged again. In this way, when the worm gear 12 controls the movement of the connector 9 and controls the upper connector 3, the two can be automatically adjusted adaptively to ensure the smooth operation of this energy storage power supply and optimize the setting and use of this energy storage power supply.

[0059] When the connector 3 moves, its top block 24 controls the moving plate 20 to move up and down via the triangular block 25. When the connector 3 moves upward and separates from the battery pack 5, the top block 24 disengages from the triangular block 25, the spring b21 returns to its original position and controls the moving plate 20 to move upward, disengaging all the inserts 22 from the latches 23 and releasing the battery pack 5 from its fixation. When the connector 3 moves downward and moves above the battery pack 5, the top block 24 controls the moving plate 20 to move downward via the triangular block 25, the spring b21 is stretched, thereby inserting the inserts 22 into the latches 23 to fix the battery pack 5, thus improving the installation stability of the battery pack 5.

[0060] The use of photovoltaic panel 26 increases the charging method of this energy storage power supply, and the photovoltaic panel 26 is set to be foldable, which increases the conversion capacity of photovoltaic panel 26 while reducing the area occupied by photovoltaic panel 26 and improving the use effect of photovoltaic panel 26.

[0061] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
