[0002] Energy storage cabinet is a device used to store and release electric energy, usually composed of battery pack, converter, control chip, cooling system and shell, etc. As energy storage cabinets are more and more widely used, the corresponding equipment in the cabinets is gradually increasing. Since most equipment needs to perform heat dissipation operations and avoid short circuits caused by external moisture entering the cabinet, it is necessary to set up a large number of waterproof air inlets and outlets in the device. However, a large number of air inlets and outlets will inevitably cause the noise generated by the operation of the equipment to be transmitted through the air inlets and outlets, thereby generating noise pollution and affecting the user experience.

[0003] Therefore, an air inlet structure and energy storage device are needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an air intake structure and an energy storage device, which have both waterproof and noise reduction functions to improve the user experience.

[0005] In order to solve the above technical problems, the utility model provides an air intake structure, comprising a first frame plate, a filter grille assembly, a second frame plate and an inner wind cover which are sequentially connected from outside to inside;

[0006] The first frame plate and the second frame plate are respectively provided with an air inlet plate and a guide plate corresponding to each other in the height direction;

[0007] The air inlet plates and the guide plates are arranged in a staggered manner, and form an S-shaped channel passing through the filter grille assembly; wherein the guide plates can intercept water drops passing through the S-shaped channel;

[0008] An air inlet chamber with a top opening is formed between the inner air cover and the filter grille assembly, and the air inlet chamber is communicated with the S-shaped channel;

[0011] The guide plate is arranged to be gradually inclined downward in a direction close to the inner wind cover.

[0012] Furthermore, when the guide plate intercepts the water droplets, the water droplets fall into the air inlet chamber.

[0013] Furthermore, a bottom wall of a side of the inner wind cover away from the second frame plate is configured to be arc-shaped to guide water droplets in the air inlet chamber to pass out to the outside of the filter grille assembly.

[0014] Furthermore, a drainage chamber with a bottom opening is formed between the first frame plate and the filter grille assembly;

[0015] When the water droplets pass through the air inlet chamber to the outside of the filter grille assembly, the water droplets can be discharged from the bottom opening.

[0016] Furthermore, the air inlet plate and the guide plate are provided in plurality to form a plurality of groups of the S-shaped channels;

Therefore, when air enters the interior of the device from the S-shaped channel, water vapor or water droplets in the air can be initially intercepted by the guide plate, and then intercepted for a second time by the inner wind hood, thereby realizing the function of multi-stage interception and effectively improving the waterproof function. In addition, since a sound insulation member is arranged on the side of the air inlet plate and the guide plate close to the inner wind hood, even if the noise generated by the operation of the equipment is transmitted in the opposite direction to the air circulation, the energy of the noise can be gradually reduced by the sound insulation member, thereby achieving the functions of both waterproofing and noise reduction, and improving the user experience.

[0030] The following will be combined with schematic diagrams to describe the air intake structure and energy storage device of the utility model in more detail, wherein the preferred embodiment of the utility model is shown, and it should be understood that those skilled in the art can modify the utility model described herein, while still achieving 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.

[0031] 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.

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes an air intake structure, including a first frame plate 1, a filter grille assembly 2, a second frame plate 3 and an inner wind cover 4 which are sequentially connected from the outside to the inside.

[0033] The first frame plate 1 and the second frame plate 3 are respectively provided with an air inlet plate 11 and a guide plate 31 corresponding to each other in the height direction.

[0034] In addition, the air inlet plates 11 and the guide plates 31 are staggered and form an S-shaped channel passing through the filter grille assembly 2 to guide air circulation so that air can enter the energy storage device to complete the heat dissipation function.

[0035] It should be noted that the guide plate 31 can intercept water droplets passing through the S-shaped channel, that is, the guide plate 31 can initially intercept moisture and water droplets in the air to prevent moisture and water droplets in the air from entering the device, thereby achieving a waterproof function.

[0036] Furthermore, an air inlet chamber with an opening at the top is formed between the inner air cover 4 and the filter grille assembly 2, and the air inlet chamber is communicated with the S-shaped channel. Since the inner air cover 4 and the filter grille assembly 2 surround the air inlet chamber with an opening at the top, the inner wall of the inner air cover 4 can also perform secondary interception on moisture and water droplets to further enhance the waterproof function.

[0037] It should also be noted that the air inlet plate 11 and the guide plate 31 are both provided with sound insulation 5 on the side facing the inner wind cover 4. Therefore, when the noise in the equipment is transmitted from the direction opposite to the air circulation, the energy of the noise can be gradually reduced with the help of two layers of sound insulation 5 to achieve the function of noise reduction.

[0038] The device is provided with a first frame plate 1, a filter grille assembly 2, a second frame plate 3 and an inner wind cover 4 which are connected in sequence from the outside to the inside, and an air inlet plate 11 and a guide plate 31 which can form an S-shaped channel are respectively provided on the first frame plate 1 and the second frame plate 3, and an air inlet chamber with a top opening is formed between the inner wind cover 4 and the filter grille assembly 2, so that when air enters the interior of the device from the S-shaped channel (such as Figure 2 The water vapor or water droplets in the air can be intercepted by the guide plate 31 and the inner wind cover 4 for many times to achieve the function of waterproofing. In addition, since the air inlet plate 11 and the side of the guide plate 31 close to the inner wind cover 4 are provided with a sound insulation member 5, even when the noise generated by the operation of the equipment is transmitted in the opposite direction to the air circulation (i.e. Figure 2 The energy of the noise can be gradually reduced by the sound insulation component 5, thereby achieving the functions of both waterproofing and noise reduction, and improving the user experience.

[0039] In this embodiment, the shapes of the air inlet plate 11 and the guide plate 31 are further limited so as to form an S-shaped channel for guiding the air circulation while intercepting moisture and water droplets in the air.

[0040] Specifically, the air inlet plate 11 is gradually tilted upwards in the direction close to the inner air cover 4, and the guide plate 31 is gradually tilted downwards in the direction close to the inner air cover 4. When the guide plate 31 intercepts water droplets, the water droplets fall into the air inlet chamber, thereby preventing the water droplets from entering the device through the top opening of the air inlet chamber, thereby causing a short circuit in the device.

[0041] In other embodiments, the bottom wall of the inner wind hood 4 on one side away from the second frame plate 3 is set to be arc-shaped to guide the water droplets in the air inlet chamber to pass through to the outside of the filter grille assembly 2, that is, to discharge the water droplets and moisture to the outside.

[0042] Specifically, a drainage chamber with a bottom opening is formed between the first frame plate 1 and the filter grille assembly 2. Therefore, when water droplets pass through the air inlet chamber to the outside of the filter grille assembly 2, the water droplets can be discharged from the bottom opening to avoid the accumulation of water droplets inside the air inlet chamber.

[0043] In a further embodiment, the air inlet plate 11 and the guide plate 31 are provided in plurality to form a plurality of S-shaped channels, and the plurality of S-shaped channels are connected to the air inlet chamber to increase the air circulation and enhance the heat dissipation effect on the equipment.

[0044] like Figure 3 As shown, preferably, in order to facilitate the disassembly and replacement of the filter element of the filter grille assembly 2, the filter grille assembly 2 is further defined herein.

[0045] Specifically, the filter grid assembly 2 includes a grid filter cotton 21 and a fixed frame plate 22 , and the grid filter cotton 21 is detachably mounted inside the fixed frame plate 22 by bolts.

[0046] The edge of the fixed frame plate 22 is provided with positioning holes connected with the first frame plate 1 and the second frame plate 3 , so that the installation is more convenient.

[0047] In this embodiment, the first frame plate 1 and the filter grille assembly 2, the filter grille assembly 2 and the second frame plate 3, and the second frame plate 3 and the inner wind hood 4 are all fixedly connected by bolts, so that the first frame plate 1, the filter grille assembly 2, the second frame plate 3 and the inner wind hood 4 can be detachably connected, which is convenient for installation and maintenance.

[0048] Preferably, the sound insulation member 5 in this embodiment can be configured as sound insulation cotton to achieve a better noise reduction effect.

[0049] Specifically, sound insulation cotton is a material that blocks the propagation of sound waves and can effectively reduce the propagation and reflection of noise. Specifically, the working principle of sound insulation cotton includes the following aspects: 1. Sound absorption: The material and structure of sound insulation cotton enable it to absorb noise in the environment and convert sound into weak heat energy to reduce the transmission of noise. 2. Sound insulation: Sound insulation cotton can prevent the propagation of sound waves, thereby reducing the reflection and transmission of noise and enhancing the comfort in the space. 3. Shock absorption: Sound insulation cotton can reduce the impact of vibration by absorbing energy and reduce the noise in the space. This is a prior art, so it will not be elaborated here.

[0050] Embodiment 2

[0051] On the other hand, the utility model also proposes an energy storage device, including the air inlet structure described in the first embodiment.

[0052] By providing an energy storage device with the air inlet structure of the first embodiment, the heat dissipation effect of the energy storage device can be effectively improved, and the short circuit of the device caused by moisture or water droplets in the air entering the inside of the device can be avoided. The noise transmitted to the outside by the air inlet structure during the operation of the energy storage device can be reduced, that is, it can have both waterproof and noise reduction functions, thereby achieving the purpose of improving the user experience.

[0053] 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.
