[0035] In use, the nitrogen tank's inlet is sealed to the air pump's outlet via a pipe and a high-pressure sealing ring, and the accumulator's inlet is sealed to the air pump's outlet. Then, the air pump is started to fill the accumulator with nitrogen from the nitrogen tank.

[0036] In related technologies, such as the accumulator nitrogen charging device disclosed in CN217762682U, a disassembly and assembly mechanism is set between the base and the nitrogen charger body to facilitate the fixing of the nitrogen charger body and also facilitate disassembly. This makes it more convenient for maintenance personnel to replace the nitrogen charger body or disassemble and repair its internal parts. However, the device requires the alignment of the connecting block and the movable plate, as well as the alignment of the second bolt and the thread groove, to be installed properly. The operation is relatively cumbersome, and the disassembly and assembly structure is exposed and easily damaged, which further affects the alignment difficulty, increases the time required for disassembly and assembly, and causes inconvenience in use.

[0037] To address some of the problems in related technologies, this application provides an energy storage device for inflation. When disassembling and repairing the inflation device body 12, simply rotate the first threaded sleeve 25 to allow the two first threaded rods 26 to slide out of the limiting groove on one side of the first slider 22. Then, lock the universal wheels at the bottom of the trolley 11 and pull the rod 24 to pull the first slider 22 out from one side of the inflation device body 12, thereby releasing the limiting of the inflation device body 12 and facilitating its removal from the concave seat 21. When installing the inflation device body 12, simply align it with the inside of the concave seat 21, insert the inflation device body 12, and then rotate the first threaded sleeve 25 to insert the first threaded rods 26 into the first slider 22 to achieve the limiting. The operation is simple, convenient, and quick. Furthermore, the entire mounting assembly 2 is located inside the concave seat 21, and the outer shell of the concave seat 21 protects the mounting assembly 2, increasing its service life.

[0038] This application is described below with reference to the accompanying drawings and specific embodiments:

[0039] Combination Figures 1-7 This application provides an energy storage device, comprising: a trolley 11, on which an energy storage device body 12 is mounted; an energy storage device 13 and a nitrogen tank 14 are snapped onto the top of the trolley 11 and located on one side of the energy storage device body 12; an installation assembly 2 is provided on the top of the trolley 11; the installation assembly 2 includes: a concave seat 21, fixedly connected to the top of the trolley 11; a first slider 22 is slidably connected inside the concave seat 21; a guide rod 23 is slidably connected to the top and bottom of the first slider 22, and a spring is sleeved on the outside of the guide rod 23; one end of the first slider 22 extends to the outside of the concave seat 21 and is fixedly connected to a rod body 24; a first threaded sleeve 25 is rotatably connected inside the concave seat 21; a first threaded rod 26 is threadedly connected inside the first threaded sleeve 25, and a groove is opened on the top of the first threaded rod 26; a locking block 27, which is fixedly connected to the inside of the concave seat 21, is slidably connected inside the groove on the top of the first threaded rod 26.

[0040] In use, after installing the accumulator 13 and nitrogen tank 14 on both sides of the housing 31 using retaining rings 41 and pins 42, the accumulator 13 and nitrogen tank 14 are then sealed to the air ports on the housing 31 via hoses. The air pump inside the inflation device body 12 is then activated, drawing nitrogen from the nitrogen tank 14 and delivering it to the accumulator 13, thus inflating the accumulator 13. When disassembling and repairing the inflation device body 12 is required, the first threaded sleeve 25 is rotated. Because the first threaded rod 26 is slidably connected to the retaining block 27, and the retaining block 27 is inserted into the groove of the first threaded rod 26, limiting the rotation of the first threaded rod 26, the first threaded rod 26 will not rotate with the first threaded sleeve 25, but will slide along the retaining block 27 inside the concave seat 21. When the two first threaded rods 26 move from one... After sliding out of the limiting groove on one side of slider 22, the limiting effect on slider 22 is released. Then, lock the universal wheel at the bottom of the trolley 11, and pull the rod 24 to pull slider 22 out from one side of the inflation device body 12, thereby releasing the limiting effect on the inflation device body 12. At this time, pull the inflation device body 12 upward from the inside of the concave seat 21 to complete the disassembly of the inflation device body 12. When installing the inflation device body 12, align the inflation device body 12 with the inside of the concave seat 21 and insert it. Then rotate the first threaded sleeve 25 so that the first threaded rod 26 is inserted into the limiting groove of slider 22 to achieve the limiting effect. The operation is simple, convenient and quick. Moreover, the entire installation component 2 is set inside the concave seat 21. The outer shell of the concave seat 21 plays a protective role for the installation component 2, increasing the service life of the installation component 2.

[0041] In some embodiments, an adjustment assembly 3 is provided on the top of the trolley 11; the adjustment assembly 3 includes: a housing 31, disposed between the accumulator 13 and the nitrogen tank 14; a second slider 32 is slidably connected inside the housing 31; a second threaded rod 33 is fixedly connected to the top of the second slider 32; a second threaded sleeve 34 is threadedly connected to the outside of the second threaded rod 33, and the second threaded sleeve 34 is rotatably connected to the housing 31; one end of the second slider 32 is sealed to the nitrogen tank 14 through a hose, and the other end of the second slider 32 is fixedly connected to a third slider 35 through a pipe, and the third slider 35 is sealed to the air pump inside the inflation device body 12 through a pipe.

[0042] When using nitrogen tank 14 for inflation, according to the Darcy-Weisbach formula, the shorter the pipe, the smaller the pressure loss, the closer the end pressure is to the gas source pressure, and the higher the inflation efficiency. Therefore, by reducing the distance between the gas port of slider 32 and the gas port of nitrogen tank 14, higher inflation efficiency can be obtained. When it is necessary to adjust the position of slider 32, rotate the threaded sleeve 34. Since slider 32 is slidably connected inside the housing 31 and does not rotate, slider 32 and threaded rod 33 move up and down together under the action of the thread. Since one side of slider 35 is sealed to one side of slider 32 through a pipe, it will move together with slider 32 as it moves up and down. Thus, high inflation efficiency can be obtained when using nitrogen tank 14 with different gas port heights.

[0043] In some embodiments, the housing 31 uses a retaining ring 41 and a pin 42 to limit the position of the accumulator 13 and the nitrogen tank 14. When installing the accumulator 13 and the nitrogen tank 14, the accumulator 13 and the nitrogen tank 14 are placed in the circular groove on the top of the trolley 11, the retaining ring 41 is rotated, and the pin 42 is inserted to limit the position of the accumulator 13 and the nitrogen tank 14, which is convenient and quick.

[0044] In some embodiments, the concave seat 21 is slidably connected to the limiting blocks 51 on both sides of the inflation device body 12 via the sliding groove 52, which is used to limit the inflation device body 12 in the horizontal direction and prevent the inflation device body 12 from sliding out from the front of the concave seat 21 when pushing the trolley 11.

[0045] In some embodiments, one end of the first slider 22 extends to the outside of the concave seat 21, the protruding part is provided with a slope, and a groove with the same size and shape as the protruding part of the first slider 22 is provided on one side of the inflation device body 12. This facilitates the compression of the slope of the first slider 22 by both sides of the inflation device body 12 when the inflation device body 12 is inserted downwards, pushing the first slider 22 into the concave seat 21 and compressing the spring outside the guide rod 23, preventing the first slider 22 from affecting the continued downward movement of the inflation device body 12. When the groove on one side of the inflation device body 12 reaches the side of the first slider 22, the first slider 22 will be pushed into the groove on one side of the inflation device body 12 under the action of the spring, thereby limiting the inflation device body 12.

[0046] In some embodiments, one side of the first threaded sleeve 25 extends to the outside of the groove formed on one side of the concave seat 21, and a rubber sleeve is fixedly connected to the outside of the first threaded sleeve 25 to increase the friction when rotating the first threaded sleeve 25.

[0047] In some embodiments, a limiting groove with the same diameter as the first threaded rod 26 is provided on one side of the first slider 22, so that the first threaded rod 26 can be inserted into the interior of the first slider 22 to limit the movement of the first slider 22.

[0048] In some embodiments, the first slider 22 and the first threaded rod 26 are a set, and two sets are provided inside the concave seat 21. The thread directions of the two first threaded rods 26 are opposite, which makes it convenient to rotate the first threaded sleeve 25 so that the two first threaded rods 26 move in opposite directions.

[0049] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0050] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
