[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] Example: Refer to Figures 1 to 5, an additional charging pack structure of an energy storage power supply, including an energy storage power supply 1. The energy storage power supply 1 refers to a device for storing and releasing electrical energy, which is usually used to balance electricity supply and demand, improve energy utilization efficiency, and support the integration of renewable energy. The energy storage power supply 1 is an existing well-known technology, and its structure and principle are not elaborated in detail here.

[0031] It also includes a power pack 2, the outer sides of the energy storage power supply 1 and the power pack 2 are both provided with an outer frame 3, and the upper and lower ends of the outer frame 3 are provided with longitudinal connectors. Specifically, the longitudinal connector includes a square groove 5 opened at the lower end of the outer frame 3, and a square block 4 adapted to the shape of the square groove 5 is fixedly connected to the upper end of the outer frame 3. The lower end of the outer frame 3 is also provided with a mounting groove 6 connected to the square groove 5, and an upper tooth plate 7 and a lower tooth plate 8 are slidably connected in sequence from top to bottom in the mounting groove 6, and the upper tooth plate 7 and the lower tooth plate 8 are spaced apart. The lower end of the outer frame 3 is also provided with a first guide groove 9 connected to the mounting groove 6, and the first guide groove 9 is slidably connected to the upper tooth plate 7. The outer frame 3 is also symmetrically provided with two second guide grooves 10 connected to the mounting groove 6. Two guide blocks are symmetrically fixedly connected to the two sides of the lower tooth plate 8, and the guide blocks are slidably connected to the second guide grooves 10. The upper tooth plate 7 and the lower tooth plate 8 are guided by setting the first guide groove 9 and the second guide groove 10 to ensure the stability of the meshing of the upper tooth plate 7 and the lower tooth plate 8 with the gears described below.

[0032] The inner side wall of the mounting groove 6 is rotatably connected with a rotating shaft, and the outer side of the rotating shaft is fixedly sleeved with a gear meshing with the upper toothed plate 7 and the lower toothed plate 8. The upper toothed plate 7 and the lower toothed plate 8 are fixedly connected with longitudinal limit plates 11 on the opposite sides, and the two longitudinal limit plates 11 are located in the same horizontal plane. A driving assembly for driving the upper toothed plate 7 and the lower toothed plate 8 to mesh with the gears is also provided in the mounting groove 6. Specifically, the driving assembly includes a threaded rod 14 rotatably connected in the mounting groove 6, and the rod body of the threaded rod 14 is threadedly connected with a threaded sleeve 15. One end of the threaded sleeve 15 close to the upper toothed plate 7 is fixedly connected with a connecting rod 16, and the other end of the connecting rod 16 is fixedly connected to the upper toothed plate 7. First, The power-up pack 2 is placed vertically just above the energy storage power supply 1, and the square groove 5 at the lower end of the power-up pack 2 is sleeved on the outer side of the square block 4 at the upper end of the energy storage power supply 1. At this time, the two longitudinal limit plates 11 are misaligned with the two fixed blocks 12. A hexagonal wrench is inserted into the hexagonal groove 17 of the threaded rod 14, and the hexagonal wrench is rotated to drive the rotating threaded rod 14 to rotate, and the threaded sleeve 15 is driven to move toward the direction close to the upper tooth plate 7, and the upper tooth plate 7 and the lower tooth plate 8 are driven to slide back to back, and the two longitudinal limit plates 11 are driven to slide back to back, until the two longitudinal limit plates 11 are inserted into the longitudinal limit grooves 13 of the two fixed blocks 12, thereby completing the longitudinal limit installation between the power-up pack 2 and the energy storage power supply 1.

[0033] The outer wall of the threaded sleeve 15 is slidably connected to the inner wall of the installation groove 6, and the outer wall of the threaded sleeve 15 is in contact with the inner wall of the installation groove 6 to ensure that the threaded sleeve 15 can slide horizontally on the rod body of the threaded rod 14 when the threaded rod 14 rotates.

[0034] A hexagonal slot 17 is formed at one end of the threaded rod 14 away from the upper tooth plate 7. The hexagonal slot 17 is matched with a hexagonal wrench. Turning the hexagonal wrench can drive the threaded rod 14 to rotate, which is easy to operate.

[0035] Two fixed blocks 12 are symmetrically fixedly connected to the upper end of the square block 4. A longitudinal limit groove 13 is provided at the opposite end of the two fixed blocks 12, and the longitudinal limit plate 11 is plugged into the longitudinal limit groove 13. The shapes of the longitudinal limit plate 11 and the longitudinal limit groove 13 are adapted. When the longitudinal limit plate 11 is plugged into the longitudinal limit groove 13, the longitudinal limit installation between the power pack 2 and the energy storage power supply 1 is completed.

[0036] A transverse connecting member is provided on the side of the outer frame 3. Specifically, the transverse connecting member includes two plug blocks 18 symmetrically slidably arranged on one side of the outer frame 3. Two sliding cavities 19 are symmetrically provided on the side of the outer frame 3. The sliding cavity 19 is slidably connected to the plug block 18. A first limit spring 20 is fixedly connected between the sliding cavity 19 and the plug block 18. A limit hole 21 is provided on the plug block 18. The plug block 18 is slidably set on the outer frame 3. When the power-up pack 2 and the energy storage power supply 1 are horizontally installed, the plug block 18 can be pressed into the sliding cavity 19, which facilitates the operation when the power-up pack 2 and the energy storage power supply 1 are horizontally installed.

[0037] When the insert block 18 completely slides into the sliding cavity 19, the first limit spring 20 is in a compressed state, and the first limit spring 20 is not in an extreme compression state, ensuring that the insert block 18 can completely slide into the sliding cavity 19, making it easy to operate when the power pack 2 and the energy storage power supply 1 are first installed horizontally and then installed vertically.

[0038] The other side of the outer frame 3 is symmetrically provided with two limit assemblies cooperating with the plug block 18. Specifically, the limit assembly includes a slot 22 provided on the outer frame 3, the slot 22 is plugged and matched with the plug block 18, and the outer frame 3 is also provided with a sliding groove 23 connected with the slot 22, the sliding groove 23 is slidably connected to the limit block 24, and a second limit spring 25 is fixedly connected between the limit block 24 and the sliding groove 23, the limit block 24 is plugged and matched with the limit hole 21, and an oblique corner is provided on the limit block 24, so that the power pack 2 and the energy storage power supply 1 are in contact with each other. During horizontal installation, the power pack 2 is pushed horizontally toward the energy storage power supply 1, and multiple plug-in blocks 18 are inserted into the slots 22. Since the limit block 24 is provided with an oblique corner, the plug-in block 18 abuts against the limit block 24 to drive the limit block 24 to slide into the sliding groove 23, and the second limit spring 25 is compressed. When the limit hole 21 on the plug-in block 18 corresponds to the position of the limit block 24, under the elastic force of the second limit spring 25, the limit block 24 slides out of the sliding groove 23 and is plugged into the limit hole 21 on the plug-in block 18, thereby completing the lateral limit installation between the power pack 2 and the energy storage power supply 1.

[0039] The outer frame 3 is also provided with an unlocking component, specifically, the unlocking component includes a groove 26 opened on the outer frame 3, the opposite ends of the two limit blocks 24 are fixedly connected with a sliding rod 27, and the two sliding rods 27 are slidably connected to the groove 26, a third limit spring 28 is fixedly connected between the sliding rod 27 and the groove 26, the opposite ends of the two sliding rods 27 are fixedly connected with a connecting magnet 30, an electromagnet 29 is provided between the two connecting magnets 30 in the groove 26, and the two ends of the electromagnet 29 are respectively N pole and S pole The property of the end of the connecting magnet 30 close to the N pole of the electromagnet 29 is the S pole, and the property of the end of the connecting magnet 30 close to the S pole of the electromagnet 29 is the N pole. When the horizontally connected power pack 2 and the energy storage power supply 1 are disassembled, the electromagnet 29 is energized. Due to the principle of attraction between different shapes, the two connecting magnets 30 approach the electromagnet 29, driving the two sliding rods 27 to slide relative to each other, and the two third limit springs 28 are stretched, driving the limit block 24 to disengage from the limit hole 21, and the power pack 2 can be moved in the direction away from the energy storage power supply 1.

[0040] The specific working principle of this invention is as follows:

[0041] It should be noted that after the electromagnet 29 is energized, the magnetic force between the electromagnet 29 and the connecting magnet 30 is greater than the elastic force of the third limit spring 28 .

[0042] First, place the power pack 2 vertically just above the energy storage power supply 1, and the square groove 5 at the lower end of the power pack 2 is sleeved on the outer side of the square block 4 at the upper end of the energy storage power supply 1. At this time, the two longitudinal limit plates 11 are misaligned with the two fixed blocks 12. Use a hexagonal wrench to insert it into the hexagonal groove 17 of the threaded rod 14, and turn the hexagonal wrench to drive the rotating threaded rod 14 to rotate, drive the threaded sleeve 15 to move in the direction close to the upper toothed plate 7, drive the upper toothed plate 7 and the lower toothed plate 8 to slide back to back, and drive the two longitudinal limit plates 11 to slide back to back until the two longitudinal limit plates 11 are plugged into the longitudinal limit grooves 13 of the two fixed blocks 12, thereby completing the longitudinal limit installation between the power pack 2 and the energy storage power supply 1. When disassembling, rotate the hexagonal wrench in the opposite direction to drive the threaded rod 14 to rotate in the opposite direction to achieve the longitudinal limit plate 11 and The two fixed blocks 12 are misaligned, and the power pack 2 is moved upward;

[0043] When the power pack 2 and the energy storage power supply 1 are installed horizontally, the power pack 2 is pushed horizontally toward the energy storage power supply 1, and multiple plug blocks 18 are inserted into the slots 22. Since the limit block 24 is provided with an oblique edge, the plug block 18 abuts against the limit block 24 to drive the limit block 24 to slide into the sliding groove 23, and the second limit spring 25 is compressed. When the limit hole 21 on the plug block 18 corresponds to the position of the limit block 24, under the elastic force of the second limit spring 25, the limit block 24 slides out of the sliding groove 23 and plugs into the limit hole 21 on the plug block 18, thereby completing the lateral limit installation between the power pack 2 and the energy storage power supply 1; when disassembling, the electromagnet 29 is energized, and the two connecting magnets 30 approach the electromagnet 29, driving the two sliding rods 27 to slide relative to each other, and the two third limit springs 28 are stretched, driving the limit block 24 to disengage from the limit hole 21, and the power pack 2 can be moved in the direction away from the energy storage power supply 1.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
