[0034] Please see Figure 1 and Figure 2 This utility model provides a charging cabinet, including a cabinet body 1, a fan 4, a noise reduction component 5, and a charger 6. The fan 4, the noise reduction component 5, and the charger 6 are all located inside the cabinet body 1. The charger 6 is used to charge the device to be charged, the fan 4 is used to guide the air circulation inside the cabinet body 1, and the noise reduction component 5 is used to reduce the noise generated by the charger 6 and the fan 4 inside the cabinet body 1.

[0035] In some embodiments, the cabinet 1 is generally rectangular in shape. Specifically, the cabinet 1 includes a frame 11, which includes support rods 112 and support columns 111 that are fixedly connected to each other. There are multiple support rods 112 and support columns 111, wherein at least two support rods 112 are arranged opposite each other and extend along the length direction of the cabinet 1, and at least four support columns 111 are arranged opposite each other in pairs and extend along the height direction of the cabinet 1.

[0036] Furthermore, the cabinet 1 also includes wall panels, which are fixedly connected to the frame 11 by at least one of the following connection methods: fastener connection, snap-fit, welding, or adhesive bonding. Specifically, the wall panels include a top panel 12 and side panels 13, which together form an accommodating space for housing the charger 6, the fan 4, and the sound-absorbing assembly 5. The side panels 13 are located between every two adjacent support columns 111 and are fixedly connected to at least one of the frame 11 and the top panel 12. Optionally, a sound-absorbing panel is attached to the inner wall of the wall panels. The sound-absorbing panel includes a porous layer, a sound-absorbing layer, and a sound-insulating layer stacked together, thereby improving the noise reduction effect of the cabinet 1.

[0037] Please combine Figure 3In some embodiments, the cabinet 1 is provided with a first partition 21 to divide the cabinet 1 along its height direction into a first receiving chamber 14 and a second receiving chamber 15. The second receiving chamber 15 is provided with a second partition 22 to divide the second receiving chamber 15 along the length direction of the cabinet 1 into an air inlet chamber 151 and an air outlet chamber 152. In one example, the first partition 21 is generally parallel to the top plate 12, and the second partition 22 is generally perpendicular to the top plate 12. The first partition 21 and the second partition 22 extend along the length and width directions of the cabinet 1, respectively, and are fixedly connected to at least one of the frame 11 and the wall panel, respectively. Optionally, the second receiving chamber 15 is located above the first receiving chamber 14, resulting in a compact structure, saving space, and facilitating installation and maintenance.

[0038] Please combine Figure 3-5 In some embodiments, at least one charger 6 is placed in the first receiving chamber 14, and at least one fan 4 is disposed in the exhaust chamber 152 for drawing gas from the first receiving chamber 14 into the exhaust chamber 152 and discharging it unidirectionally through the exhaust port 132. Further, the cabinet 1 is provided with an air inlet 131 and an air outlet 132 for connecting the external environment with the air inlet chamber 151 and the exhaust chamber 152, respectively. The first partition 21 is provided with a first vent 211 connecting the air inlet chamber 151 and the first receiving chamber 14, and a second vent 212 connecting the exhaust chamber 152 and the first receiving chamber 14.

[0039] Please see Figure 6 and Figure 7 Optionally, the fan 4 is disposed in the area corresponding to the second vent 212 within the air outlet chamber 152. Optionally, the fan 4 is at least partially housed within the second vent 212 and installed on the first partition 21. When the fan 4 is running, it can guide the gas in the air inlet chamber 151 into the first receiving chamber 14 through the first vent 211, and into the air outlet chamber 152 through the second vent 212 and discharged through the air outlet 132, thereby increasing the air circulation speed inside the cabinet 1 and increasing the air intake volume inside the cabinet 1, preventing heat accumulation in the charger 6, and thus improving heat dissipation performance.

[0040] Please combine Figure 3 Optionally, the first vent 211 is located on the side of the first partition 21 away from the air inlet 131, and the second vent 212 is located on the side of the first partition 21 away from the air outlet 132. In one example, the first partition 21 has a gap between the end near the air inlet 131 and the side plate 13, thereby forming the first vent 211.

[0041] In one example, the air inlet 131 and the air outlet 132 are respectively located on two opposite sides of the cabinet 1. Optionally, the projections of the air inlet 131 and the air outlet 132 along the width direction of the cabinet 1 do not overlap at least partially, that is, the air inlet 131 and the air outlet 132 are staggered in the length direction of the cabinet 1. This can extend the air circulation path inside the cabinet 1, which is beneficial for removing heat and avoiding local overheating, thereby improving the heat dissipation effect.

[0042] Furthermore, a heat insulation plate 3 is provided within the first accommodating chamber 14 along the length of the cabinet 1. Optionally, the heat insulation plate 3 is approximately perpendicular to the top plate 12 and is fixedly connected to at least one of the frame 11 and the side plate 13, dividing the first accommodating chamber 14 into an air inlet chamber 141 and an air outlet chamber 142. The air inlet chamber 141 and the air outlet chamber 142 are respectively connected to the air inlet chamber 151 and the air outlet chamber 152 through a first vent 211 and a second vent 212. In this example, at least one charger 6 is placed in the air inlet chamber 141. It should be noted that all the above-mentioned plates can be fixedly connected to related components by means of snap-fit, welding, adhesive bonding, or fastener connection. In this example, the charger 6 is provided with a heat dissipation channel, and the heat insulation plate 3 has heat dissipation holes communicating with the heat dissipation channel. By providing the heat insulation plate 3 within the first accommodating chamber 14, airflow outside the heat dissipation channel within the first accommodating chamber 14 can be blocked, preventing convection of hot and cold air and ensuring heat dissipation performance.

[0043] Please continue reading. Figure 3 In some embodiments, the silencing assembly 5 includes a first silencing assembly 51 and a second silencing assembly 52 respectively disposed in the air intake chamber 151 and the air outlet chamber 152. Specifically, the first silencing assembly 51 includes at least two first silencing strips 511 arranged sequentially at intervals along the length direction of the cabinet 1. The first silencing strips 511 are located in the air intake chamber 151 on the side near the air intake port 131, and there is an air intake channel between two adjacent first silencing strips 511. The second silencing assembly 52 includes at least two second silencing strips 521 arranged sequentially at intervals along the length direction of the cabinet 1. The second silencing strips 521 are located in the air outlet chamber 152 on the side near the air outlet port 132, and there is an air outlet channel between two adjacent second silencing strips 521. Understandably, the air intake channel between the first silencer strips 511 is used to guide outside air into the air intake chamber 151 through the air intake port 131. The first silencer strips 511 can absorb the noise generated by the gas passing through the air intake channel, ensuring the quietness of the charging cabinet. The air outlet channel between the second silencer strips 521 is used to guide the gas in the air outlet chamber 152 out through the air outlet 152. The second silencer strips 521 can absorb the noise generated by the gas passing through the air outlet channel, ensuring the quietness of the charging cabinet.

[0044] See Figure 2 and Figure 3In one specific example provided in this embodiment, the first silencing strip 511 and the second silencing strip 521 are rectangular plates, making the air intake channel and the air outlet channel a straight air duct. In other embodiments, the first silencing strip 511 and the second silencing strip 521 are bent plate structures, so that the air intake channel and the air outlet channel have at least one bend in their air duct extension direction. Therefore, this application does not limit the specific structure of the first silencing strip 511 and the second silencing strip 521.

[0045] In some embodiments, the first sound-absorbing strip 511 and the second sound-absorbing strip 512 are made of porous sound-absorbing materials with high sound absorption coefficients, such as polyurethane foam, mineral fiber cotton or glass fiber, to absorb the sound wave energy that comes into contact with their surfaces, thereby achieving the effect of noise reduction.

[0046] In some embodiments, the first silencing strip 511 and the first partition 21 or the top plate 12, and the second silencing strip 521 and the first partition 21 or the top plate 12 are fixed by any one of the following connection methods: adhesive bonding, snap-fitting, and fastener connection, without limitation.

[0047] The fan generates operating noise during operation. While the second sound-absorbing strip 521 at the air outlet 132 absorbs the noise from the exhaust air, some fan noise still escapes. Therefore, see [link to relevant documentation]. Figure 2 and Figure 3 In one specific example provided by this utility model, the second noise reduction component 52 further includes a sound insulation plate 522. The sound insulation plate 522 is located on the side of the fan 4 near the air outlet 132 and is fixedly connected to the cabinet 1. The sound insulation plate 522 is provided with a third vent 523 for air circulation. The sound insulation plate 522 is used to reduce the noise generated by the fan 4 during operation, which is beneficial to improving the noise reduction effect of the charging cabinet. In one example, the sound insulation plate 522 is located between the fan 4 and the second noise reduction strip 521. Specifically, the sound insulation plate 522 is approximately perpendicular to the top plate 12 and extends along the length direction of the cabinet 1. The opposite ends of the sound insulation plate 522 are fixedly connected to the second partition 22 and the side plate 13, respectively. Optionally, the sound insulation plate 522 has a gap with at least one of the top plate 12 and the first partition 21, thereby forming the aforementioned third vent 523.

[0048] In one example, the bottom of the charging cabinet is provided with a base for placing the cabinet 1. The base has a first step and a second step. Specifically, the first step protrudes from the upper surface of the base to form the first step, and the second step protrudes from the upper surface of the first step. The side panel 13 abuts against the base and is fixedly connected to the side of the first step by adhesive to prevent water from entering the cabinet 1, thereby improving the airtightness. The charger 6 is placed on the upper surface of the second step, which further prevents water from contacting the charger 6, thereby ensuring that the charger 6 works normally.

[0049] Please continue reading. Figure 3In some embodiments, the charging cabinet of this invention further includes louvers 71, with at least two louvers 71 respectively positioned on the cabinet 1 near the air inlet 131 and the air outlet 132 to regulate airflow. Furthermore, the louvers 71 ensure air circulation while preventing leaves or rainwater from entering the cabinet 1, thereby ensuring the normal operation of the charger 6.

[0050] The charging cabinet of this utility model also includes mounting rings 72. Optionally, there are four mounting rings 72, which are arranged in pairs opposite to each other on the cabinet body 1. In one example, the mounting rings 72 pass through the top plate 12 and are fixedly connected to the support frame 11 by welding, fasteners, or other means. In another example, the mounting rings 72 are integrally connected or fixedly connected to the top plate 12.

[0051] Please see Figure 8 The charging cabinet of this utility model also includes a drain pipe 73. Optionally, the drain pipe 73 is located at the edge of the cabinet body 1. In one example, the top plate 12 has a drain hole 121. One end of the drain pipe 73 communicates with the drain hole 121 and is fixedly connected to the top plate 12. The other end of the drain pipe 73 passes through the side plate 13 or extends from the bottom of the side plate 13. When water drips onto the outer surface of the top plate 12, it can flow along the surface of the top plate 12 into the drain hole 121 and be discharged through the drain pipe 73, preventing water or other liquids from accumulating on the surface of the top plate 12, thereby preventing water or other liquids from leaking into the cabinet body 1. Optionally, there are multiple drain pipes 73, which are spaced apart in the cabinet body 1 along a first direction.

[0052] Please continue reading. Figure 1 The charging cabinet of this utility model also includes a maintenance door 74. The cabinet body 1 has an installation opening for accommodating the maintenance door 74. The maintenance door 74 selectively seals the installation opening, so that the cabinet body 1 has an open state and a closed state that respectively exposes and seals the installation opening. In one example, the maintenance door 74 is mounted in the area corresponding to the installation opening of the cabinet body 1 via a hinge or slide rail assembly (not shown). Optionally, there are two maintenance doors 74, which are respectively located on opposite sides of the cabinet body 1 for convenient maintenance.
