By the top filling structure 1, the side filling structure 2 and the bottom filling structure 3, the tray support 200 or the material in the inflatable shell 100 can be supported, the stability of the tray support 200 in use or the material in static state is ensured, the empty space in the inflatable shell 100 can be filled, the internal volume is reduced, the volume of the gas to be filled into the inflatable shell 100 is effectively reduced, the consumption of the gas is reduced, and the production cost is controlled. At the same time, due to the reduction of the volume of the inflatable shell 100, the inflation and pressurization time is significantly shortened, and the production efficiency is effectively improved.

[0045] In other embodiments, the inflatable energy-saving device can be selected according to the shape of the inflatable shell 100 to be filled, and at least one of the top filling structure 1, the side filling structure 2 and the bottom filling structure 3 is included.

[0046] Continuing to refer to Figure 2 In this embodiment, the tray support 200 is further arranged in the inflatable shell 100. The tray support 200 includes a support plate and a plurality of support rods, the plurality of support rods are arranged at intervals along the circumference of the base 102, the support plate is horizontally placed and connected between the plurality of support rods. The top filling structure 1 is arranged between the top of the support rod and the inner top wall of the cover 101, and the side filling structure 2 is arranged between the side of the support rod and the inner side wall of the cover 101, so as to fill the empty space on the bottom and the side of the cover 101.

[0047] Specifically, as Figure 2 shown in the drawings, in this embodiment, the support plate includes a top support plate 201 connected to the top of the plurality of support rods. The top filling structure 1 includes a top filling piece 12 arranged on the side of the top support plate 201 facing the top of the cover 101, and the top surface of the top filling piece 12 matches and adheres to the inner top wall of the cover 101. The top filling piece 12 is reliably supported by the top support plate 201, and the top surface of the top filling piece 12 matches and adheres to the inner top wall of the cover 101, so as to better fill the empty space on the top of the inflatable shell 100. It can be understood that the top support plate 201 needs to have a certain structural strength to ensure the reliability of the support. Preferably, the top support plate 201 can be selected as a SUS sheet metal in the prior art, i.e. a stainless steel sheet metal piece.

[0048] Specifically, the top filler 12 comprises a plurality of top filler plates 121, which are sequentially stacked on the top support plate 201. In this embodiment, since the inflatable shell 100 is a pressurized cylinder, the pressurized cylinder is in the shape of a bell jar, that is, the top of the pressurized cylinder is in the shape of a circular arc, and therefore the top of the top filler 12 is adapted to the shape of the top of the pressurized cylinder. Among the plurality of stacked top filler plates 121, the cross-sectional size of each layer of top filler plates 121 gradually decreases in the direction away from the top support plate 201. Exemplarily, the top filler plate 121 can be made of PP material, or can be made of PE or Teflon material. Of course, if the top cross section of the inflatable shell 100 is in the shape of a rectangle or a square or other polygonal shape, the shape of the top filler plate 121 is designed according to the shape of the cross section to be filled, which is not described herein.

[0049] It should be noted that the design of the plurality of stacked top filler plates 121 helps the operator to cut and process the top filler plates 121 according to the various shapes of the inflatable shell 100, and to realize modular assembly, thereby improving the work efficiency.

[0050] Further specifically, the top filler structure 1 further comprises a top connecting member (not shown in the figure). The top connecting member is used to fix the top filler 12 on the top support plate 201. The top connecting member comprises a top connecting screw and a top connecting nut. The top connecting screw is arranged on the top support plate 201 and extends towards the top of the cover body 101, a first through hole is formed on the top filler 12, the top connecting screw passes through the first through hole and is screwed to the top connecting nut. In this embodiment, a first through hole is formed on each top filler plate 121 at a position corresponding to the top connecting screw, and the top connecting screw passes through the first through holes of the plurality of top filler plates 121 in sequence and is screwed to the top connecting nut.

[0051] More specifically, the top connecting member is provided in plurality, and the plurality of top connecting members are arranged in an array. In this embodiment, the plurality of top connecting members are arranged in a circumferential array to ensure that each top filler plate 121 is balanced in force.

[0052] Optionally, continuing to refer to Figure 2 , the tray support 200 further comprises a side support plate 202, which is arranged vertically and connected to one side of the support rod facing the inner side wall of the cover body 101. The side filler structure 2 comprises a side filler 22.

Preferably, the side support plate 202 can also be a SUS sheet metal in the prior art, that is, a stainless steel sheet metal.

[0053] It can be understood that the side filling structure 2 is used to fill the empty space of the side of the tray support 200 in the inflatable shell 100. Since the tray support 200 needs to enter and exit the inflatable shell 100 through the opening of the cover 101, the side filling structure 2 is only arranged on three sides in the inflatable shell 100 to avoid the opening of the cover 101.

[0054] Specifically, the side filling piece 22 includes a plurality of side filling plates 221, which are sequentially stacked on the side support plate 202, and the longitudinal cross-sectional size of the plurality of side filling plates 221 gradually decreases in the direction close to the inner side wall of the cover 101. Exemplarily, the side filling plate 221 can be made of PP material, or can be made of PE or Teflon material.

[0055] Further specifically, the side filling structure 2 further includes a side connecting piece 23, which includes a side connecting screw and a side connecting nut. The side connecting screw is arranged on the side support plate 202 and extends towards the inner side wall of the cover 101. A second through hole is formed on the side filling piece 22, the side connecting screw passes through the second through hole, and is screwed with the side connecting nut. The side filling structure 2 is arranged in the same way as the top filling structure 1, and this embodiment will not be repeated here.

[0056] Optionally, in the embodiment, the bottom filling structure 3 includes a plurality of bottom filling pieces 31. Each bottom filling piece 31 is block-shaped, and the plurality of bottom filling pieces 31 are combined in the base 102 of the inflatable shell 100 and fill the empty space of the base 102. The entire filling space inside the base 102 of the inflatable shell 100 is divided into a plurality of block-shaped areas, and each block-shaped area is filled by one bottom filling piece 31. Such arrangement is not only convenient for the manufacture of the bottom filling piece 31, but also helps to put the single bottom filling piece 31 into the base 102 of the inflatable shell 100.

[0057] In the embodiment, the top filling structure 1 and the side filling structure 2 are detachably connected. The top filling structure 1 and the side filling structure 2 can be detachably connected by screws or the like to ensure the structural integrity of the inflatable energy-saving device. Correspondingly, the side filling structure 2 and the bottom filling structure 3 can also be detachably connected by screws or the like.

[0058] Optionally, as Figure 3As shown, in another embodiment, the top filling structure 1 is a one-piece structure. The top filling structure 1 is integrally formed according to the top shape of the cover 101 of the to-be-inflated shell 100 by a process such as injection molding, and has good structural integrity and high processing efficiency due to one-time forming without assembly. Correspondingly, the side filling structure 2 and the bottom filling structure 3 can also be one-piece structures. Exemplarily, the top filling structure 1, the side filling structure 2 and the bottom filling structure 3 can be made of PP material, or can be made of PE or Teflon material.

[0059] In the embodiment, the standing cavity empty volume of one bell-shaped pressurizing cylinder is 915L, the total volume of the filling part of the inflation energy-saving device is 358L, the proportion is 39%, that is, 39% of the original nitrogen consumption can be saved in one cycle, which greatly reduces the production cost. At the same time, the site measurement shows that the pressurizing and standing cycle time of the bell-shaped pressurizing cylinder after filling is shortened by 2min, and the battery pressurizing and standing process time can be optimized through volume optimization, which effectively improves the production efficiency. Moreover, since the high pressure reaches 650kpa during the pressurizing cycle of the pressurizing cylinder, the filling part can share part of the pressure of the high-pressure nitrogen on the cylinder body after filling, which helps to prolong the service life of the pressurizing cylinder. Further, the filling part of the inflation energy-saving device increases the overall weight of the tray support 200 in the pressurizing cylinder, enhances the stability and strength of the tray support 200, increases the stability when taking and placing the tray support 200, reduces shaking, reduces the failure rate, and also improves the production efficiency to a certain extent.
