[0028] Please refer to the attached Figure 1 and the attached Figure 2, this embodiment relates to a battery swapping cabinet, which includes a cabinet body 1. The cabinet body 1 includes two opposite side walls 11, a top wall 12 and a rear wall 13. The two ends of the top wall 12 are respectively connected to the two side walls 11. A first guide groove 121 extending along the horizontal direction is provided on the top wall 12. A second guide groove 111 extending along the vertical direction is provided on the side wall 11. The first guide groove 121 and the second guide groove 111 are communicated with each other, and water can be discharged into the ground through the first guide groove 121 and the second guide groove 111 in sequence; the rear wall 13 is connected to both the top wall 12 and the two side walls 11. A first air inlet hole 112 is provided on the side wall 11, and an air outlet hole 131 is provided on the rear wall 13, and a fan 132 is provided on the rear wall 13 relative to the air outlet hole 131.

[0029] In this embodiment, the cabinet body 1 is in the shape of a cuboid. The side wall 11, the top wall 12 and the rear wall 13 of the cabinet body 1 are respectively metal plate members. The two ends of the top wall 12 are respectively welded and connected to the two opposite side walls 11. A first guide groove 121 is provided on one side edge of the top wall 12 away from the rear wall 13. The first guide groove 121 is a U-shaped structure and extends along the horizontal direction. A second guide groove 111 is provided on one side edge of the side wall 11 away from the rear wall 13. The two notches of the first guide groove 121 are respectively communicated with the two second guide grooves 111 to ensure that after rainwater and other liquids are collected through the first guide groove 121, they flow into the second guide groove 111 and are discharged into the ground, thereby preventing rainwater from entering the interior of the battery swapping cabinet, short-circuiting or damaging the electrical components inside the battery swapping cabinet, and ensuring the normal operation and service life of the internal electrical components; further, the rear wall 13 can be connected to both the top wall 12 and the two side walls 11 by welding. An air outlet hole 131 is opened on the rear wall 13, and a fan 132 is provided at the position corresponding to the air outlet hole 131. The fan 132 can be turned on when the battery 2 is charging inside the battery swapping cabinet. The air flow enters from the first air inlet hole 112 and is discharged from the air outlet hole 131 under the acceleration of the fan 132. By increasing the gas flow rate to accelerate heat dissipation, the heat dissipation efficiency is improved, and the problem of poor heat dissipation is solved. At the same time, by directly using the fan 132 for heat exchange, it is possible to avoid using a complex heat exchange module to dissipate heat from the battery swapping cabinet, ensuring the compactness and miniaturization of the entire battery swapping cabinet, and also reducing costs.

[0030] Optionally, the cabinet body 1 further includes a front door 14 opposite to the rear wall 13. The front door 14, the two side walls 11, the top wall 12 and the rear wall 13 jointly enclose an installation space. A frame 3 for placing the battery 2 is provided in the installation space. The front door 14 is pivotally connected to the frame 3.

[0031] In this embodiment, the front door 14 is also a metal plate member. The front door 14 is arranged opposite to the rear wall 13. At the same time, the front door 14 is rotatably connected to the column of the frame 3 through a hinge. The front door 14 can be rotated to open and close, which is convenient for putting in and taking out the battery 2. During the charging process after the battery 2 is put in, closing the front door 14 can ensure the use safety.

[0032] Further, a sealing strip 141 is provided on the front door 14. When the front door 14 is in the closed state, the sealing strip 141 is pressed against the second guide groove 111.

[0033] In this embodiment, a sealing strip 141 extending along the vertical direction is provided on the side of the front door 14 away from the hinge. After the front door 14 is closed, the sealing strip 141 is squeezed and deformed to seal between the front door 14 and the side wall 11, preventing impurities such as dust from entering the interior of the cabinet body 1. At the same time, the sealing strip 141 is pressed against the second guide groove 111, which also ensures that rainwater does not leak or overflow during the drainage process of the second guide groove 111, further improving the sealing performance inside the cabinet body 1.

[0034] Optionally, a socket 4 and a charger 5 are provided on the frame 3.

[0035] In this embodiment, the socket 4 can be fixedly connected to the frame 3 by bolts, and multiple sockets 4 can be arranged along the vertical direction in the middle of the frame 3. The charger 5 is the core device in the charging cabinet, responsible for converting electrical energy into a form of electrical energy suitable for the battery 2 of the unmanned vehicle to use, so as to meet the charging requirements of the unmanned vehicle. The charger 5 is directly placed on the frame 3 and can be fixed by snap connection or screw connection.
