[0002] As an important component of battery energy storage systems, energy storage boxes have been widely used in new energy, smart grids, energy-saving technologies and other fields.

[0003] The energy storage box generally contains a large number of batteries. When the batteries are running, they will generate a lot of heat, causing the temperature to rise. In order to make the batteries work at a suitable temperature, air conditioning is generally used to control the temperature of the energy storage box. An air duct connected to the air conditioner is set in the energy storage box so that the air outlet of the air duct faces the batteries.

[0004] However, during the production and transportation of existing energy storage boxes, due to factors such as actual manufacturing, deformation and installation, such as the unevenness of the container chassis, the processing tolerance of the battery rack, and the deformation of the container during transportation, a gap is easily formed between the air duct and the air outlet of the air conditioner, resulting in air leakage at the air outlet of the air conditioner.

[0013] Furthermore, the elongated hole is configured as a keyway structure, and a plurality of protruding modules are arranged inside;

[0014] The plugging hole is formed between two adjacent protruding modules and between the protruding module and the end wall of the long hole.

[0015] Furthermore, the protrusion module includes two symmetrically arranged protrusion units;

[0016] The protrusion unit is arranged on the top wall or the bottom wall of the inner cavity of the elongated hole and has symmetrically arranged arc-shaped outer walls, and the extension lines of the two arc-shaped outer walls intersect.

[0017] Furthermore, the slot is configured as a threaded slot, and the air duct fixing piece is configured as a screw fastener.

[0018] Furthermore, the length of the elongated holes is 2cm-4cm.

[0019] Furthermore, a reinforced skirt is provided on the periphery of the opening of the external air duct close to one end of the air conditioner.

[0020] Furthermore, a connecting flange is provided at an opening at one end where the external air duct is connected to the air duct main body.

[0021] Furthermore, a sealing strip is provided at the opening at one end of the inner air duct connected to the air conditioner, and the cross-section of the sealing strip is a C-shaped structure.

[0047] The air duct structure and energy storage box of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0048] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0049] Embodiment 1

[0050] like Figures 1 to 3 As shown, the embodiment of the utility model proposes an air duct structure, including an air duct body 1 and a retractable air duct 2. The air duct body 1 and the air outlet of the air conditioner 9 are connected by the retractable air duct 2, so that when the air conditioner 9 is connected to the air duct structure, when a gap or misalignment occurs due to the deformation of the energy storage box and the processing tolerance of the box, the elongation of the retractable air duct 2 can be adjusted to meet the docking requirements, thereby effectively reducing the accuracy requirements for the installation connection at the air duct structure, and correspondingly reducing the after-sales risks of factory goods after shipment.

[0051] The retractable air duct 2 includes an outer air duct 21 , an inner air duct 22 and an air duct fixing member 23 .

[0052] One end of the outer air duct 21 is fixedly connected to the air duct body 1 , and an outer wall is provided with a long hole 3 .

[0053] A plurality of plug holes 31 matching the air duct fixing member 23 are formed in the elongated hole 3, and the plug holes 31 are used to limit the position of the air duct fixing member 23 in the extension direction of the elongated hole 3. That is, the air duct fixing member 23 can be inserted into any plug hole 31 in the elongated hole 3 to position the inner air duct 22, and because the plug holes 31 can limit the position of the air duct fixing member 23 in the extension direction of the elongated hole 3, when the air duct fixing member 23 is locked, the air duct fixing member 23 will not be affected by external forces and will not be misplaced or shaken in the elongated hole 3, so as to further improve the positioning effect of the air duct fixing member 23.

[0054] It should be noted that in actual application, the outer air duct 21 and the inner air duct 22 are not locked too tightly, that is, the air duct fixing member 23 only plays a pre-fixing role between the outer air duct 21 and the inner air duct 22, so that when arriving at the transportation location, through inspection, it is detected whether there is looseness or deformation between the outer air duct 21 and the inner air duct 22. If there is, the air duct fixing member 23 can be moved in the long hole 3 to achieve the effect of motion compensation, ensuring that the elongation of the outer air duct 21 and the inner air duct 22 is at a certain value to meet the application requirements. That is, by setting the long hole 3, a certain amount of deformation and structural activity margin is provided for the misalignment or shaking between the outer air duct 21 and the inner air duct 22, so that the connection here is not easy to fall off or directly damaged.

[0055] The inner air duct 22 is embedded in the outer air duct 21 and is slidable relative to the outer air duct 21 , and one end of the inner air duct 22 can be connected to the air conditioner 9 , so that the air volume from the air outlet of the air conditioner 9 can pass through the retractable air duct 2 to the air duct body 1 .

[0056] In addition, the outer wall of the inner air duct 22 is provided with a groove, and the groove can overlap with the plug hole 31, so as to facilitate the locking and positioning of the air duct fixing part 23, thereby achieving the fixation of the inner air duct 22 and the outer air duct 21, that is, realizing the function of quickly adjusting the extension of the retractable air duct 2.

[0057] Specifically, the air duct fixing member 23 passes through the plug hole 31 and the slot, and can abut against the outer air duct 21 , so that the inner air duct 22 remains fixed relative to the outer air duct 21 .

[0058] The device forms an air duct structure that docks with the air conditioner 9 by providing an air duct main body 1 and a retractable air duct 2, so that when a gap appears between the air conditioner 9 and the air duct structure due to the deformation of the energy storage box, the elongation of the retractable air duct 2 can be adjusted to meet the docking requirements, thereby effectively reducing the accuracy requirements for the installation of the air duct structure and correspondingly reducing the after-sales risks after the factory goods are shipped.

[0059] Furthermore, by providing a retractable air duct 2 including an outer air duct 21, an inner air duct 22 and an air duct fixing member 23, and respectively providing a long hole 3 and a slot on the outer wall of the outer air duct 21 and the outer wall of the inner air duct 22, the air duct fixing member 23 can achieve the relative fixation between the inner air duct 22 and the outer air duct 21 by penetrating the long hole 3 and the slot, thereby realizing the function of facilitating the adjustment of the elongation of the retractable air duct 2. In addition, since there are a plurality of plug holes 31 in the long hole 3, and the plug holes 31 can limit the air duct fixing member 23 in the direction along which the long hole 3 extends, when the air duct fixing member 23 is connected, it will not shake or deviate in the direction in which the long hole 3 extends due to external factors, thereby further improving the stability of the inner air duct 22 and the outer air duct 21 when they are in a relatively fixed state.

[0060] like Figure 3 As shown, in this embodiment, the long hole 3 is arranged in a sawtooth structure to form a plurality of plug holes 31, so as to limit the position of the air duct fixing member 23. That is, the plug holes 31 can be formed around two adjacent tooth-shaped protrusions to limit the position of the air duct fixing member 23.

[0061] Embodiment 2

[0062] like Figure 4 and Figure 5 As shown, the difference between this embodiment and the first embodiment lies in the shape of the elongated hole 3, so that the number of the plug-in holes 31 can be increased on the basis of the elongated holes 3 of the same length, thereby improving the adjustment accuracy of the extension amount of the telescopic air duct 2.

[0063] The elongated hole 3 is configured as a keyway structure, and a plurality of protruding modules are disposed inside, and the plug-in hole 31 is formed between two adjacent protruding modules and between the protruding modules and the end wall of the elongated hole 3 .

[0064] like Figure 5 As shown, specifically, the protrusion module includes two symmetrically arranged protrusion units 4.

[0065] The protrusion unit 4 is arranged on the inner cavity top wall or bottom wall of the long hole 3 and has a symmetrically arranged arc-shaped outer wall. The arc-shaped outer walls of four protrusion units 4 form a plug-in hole 31, thereby completing the limiting of the air duct fixing part 23.

[0066] It should be particularly noted that the arc-shaped outer wall matches the size of the air duct fixing piece 23, and the extension lines of the two arc-shaped outer walls intersect, thereby correspondingly reducing the size of the space occupied by the protruding unit 4. In this way, the number of protruding units 4 can be increased within a limited length range, thereby correspondingly increasing the number of plug-in holes 31. Since the adjustment accuracy of the telescopic air duct 2 depends on the moving distance of the air duct fixing piece 23, the purpose of improving the adjustment accuracy of the elongation of the telescopic air duct 2 can be achieved by increasing the number of plug-in holes 31.

[0067] In other embodiments, the slots and the air duct fixing member 23 are further defined so as to better fix the inner air duct 22 and the outer air duct 21 together.

[0068] Specifically, the slot is set as a threaded groove, and the air duct fixing piece 23 is set as a screw fastener. When the screw fastener passes through the plug hole 31 to connect with the threaded groove, and the skirt of the screw fastener abuts against the outer wall of the outer air duct 21, the relative fixation between the inner air duct 22 and the outer air duct 21 can be achieved, and the connection is more convenient.

[0069] In a further embodiment, the length of the elongated hole 3 is 2 cm-4 cm.

[0070] In order to improve the bearing strength of the outer air duct 21 on the inner air duct 22 , a reinforcing skirt 5 is provided at the periphery of the opening of the outer air duct 21 close to the air conditioner 9 .

[0071] In addition, a connecting flange 6 is provided at one opening of the outer air duct 21 connected to the air duct main body 1 , so as to facilitate rapid assembly of the outer air duct 21 and the air duct main body 1 .

[0072] In other embodiments, in order to improve the sealing effect when the inner air duct 22 is connected to the air conditioner 9, a sealing strip 7 is further provided. Specifically, a sealing strip 7 is provided at the opening of one end where the inner air duct 22 is connected to the air conditioner 9, and the cross section of the sealing strip 7 is a C-shaped structure.

[0073] Preferably, the opening of one end of the inner air duct 22 connected to the air conditioner 9 is arranged with an angle structure around it, and the angle structure is semicircular. By arranging the opening of the inner air duct 22 in a semicircular shape around it, it is easy to transition and engage the C-shaped sealing strip 7, thereby achieving the purpose of facilitating the installation of the sealing strip 7.

[0074] Embodiment 3

[0075] like Figure 6 As shown, this embodiment further proposes an energy storage box based on the second embodiment, including a box body 8, an air conditioner 9, a battery rack 10 and the air duct structure described in the second embodiment.

[0076] The air conditioner 9 is disposed on a door panel of the box body 8 , and the battery rack 10 is disposed inside the box body 8 .

[0077] The air duct structure is arranged on the top wall of the inner cavity of the box body 8, and the air inlet of the air duct structure (i.e., the inner air duct 22) is connected to the air conditioner 9, and the air outlet of the air duct structure (i.e., the outlet of the air duct body 1) is facing the battery rack 10, so as to better cool the battery rack 10.

[0078] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
