[0039] Reference Figure 1 , Figure 2 and Fig. 9The limit slider 12 is slidably connected to the inside of the fixed shell 10, the pull rope 13 passes through the fixed shell 10 on one side close to the rotating door 14, the limit block 5 is slidably connected to the inside of the installation shell 3, the interior of the cavity 8 is connected to the interior of the installation shell 3 through the connecting hole 9, and a plurality of battery blocks 17 are arranged inside the installation shell 2. The battery block 17 is a prior art and will not be described in detail. The front side of the chassis 1 is located on one side of the pull rope 13 and is rotatably connected to a pulley 16, which can change the direction of the force of the pull rope 13. The outer side of the limit driving block 1507 is fixedly connected to a pull column 1509, and the pull column 1509 can drive the limit driving block 1507 to move. The bottom of the wind collecting hood 1501 is fixedly connected to a dust guide plate 1514, which can guide dust downward. The limit plate 1512 is slidably connected to the inside of the fixed shell 1510, and the cleaning block 1513 passes through the fixed shell 1510 on one side close to the filter plate 1502.

[0040] Working principle: when replacing the power battery of the electric vehicle, pull the revolving door 14, and the revolving door 14 rotates to drive the pull rope 13 to move in the direction of the revolving door 14, and then drive the limit slider 12 to slide in the direction of the revolving door 14. After the limit slider 12 slides, it can stretch the tension spring 11. When the limit slider 12 moves to the side of the fixed shell 10 close to the revolving door 14, it drives the fixed shell 10 to move in the direction of the revolving door 14. After the fixed shell 10 moves in the direction of the revolving door 14, it can drive the mounting shell 2 to move in the direction of the revolving door 14, and then drive the battery block 17 to move in the direction of the revolving door 14. At this time, it can drive the connecting bent rod 7 to move in the direction of the revolving door 14. After the connecting bent rod 7 moves, it can drive the sliding column 6 to move in the direction of the rotating door 14, and then drive the limit block 5 to move in the direction of the rotating door 14, and then drive the tension spring 4 to stretch. At this time, the liquid in the cavity 8 enters the interior of the mounting shell 3 along with the movement of the limit block 5. When the limit block 5 moves to the inside of the mounting shell 3 close to the connecting bent rod 7, the mounting shell 2 moves to the maximum distance. At this time, the mounting shell 2 can be moved to the outside of the chassis 1, and then the battery block 17 can be replaced conveniently. Therefore, the battery block 17 can be replaced without disassembling the bottom plate of the electric vehicle, which saves time and effort. When the battery replacement is completed, the rotating door 14 is loosened, and the limit block 5 can be pulled to the inside of the mounting shell 3 under the reaction force of the tension spring 4. Since there is liquid inside the mounting shell 3, when the limit block 5 moves toward the inside of the mounting shell 3, the liquid can be pressed into the inside of the cavity 8 through the connecting hole 9. Since the hole of the connecting hole 9 is relatively small, there will be resistance, which can make the limit block 5 move slowly, thereby making the sliding column 6 move slowly, so that the connecting bent rod 7 moves slowly. After the connecting bent rod 7 moves slowly, the speed at which the mounting shell 2 enters the inside of the chassis 1 will also become slow, thereby avoiding the battery block 17 from being damaged due to vibration caused by too fast movement when resetting. At the same time, when the vehicle moves quickly, a large airflow passes through the wind gathering cover 1501 and enters the inside of the air guide 1515, thereby The small holes on the air duct 1515 can be used to spray the air onto the battery block 17. Since the small holes on the air duct 1515 are used for spraying, the air can flow into and out of the air condenser 1501 until it is far away from the air condenser 1501. Therefore, the entire battery quick-change assembly can have airflow entering, thereby preventing the airflow from staying only near the air condenser 1501. At the same time, when the air enters, the impurities in the air can be filtered through the filter plate 1502. When the filter plate 1502 is replaced, the pull column 1509 is first pushed downward to drive the limit driving block 1507 to move downward, and then the buckle 1508 can be driven to rotate, so that the buckle 1508 can be moved into the interior of the installation slot 1505.Then, the engagement between the buckle 1508 and the socket 1504 can be released, and the plug 1503 can be pulled outward. After the plug 1503 is pulled outward, the filter plate 1502 can be pulled outward. When the filter plate 1502 moves outward, it can pass through the cleaning block 1513, so that the dust on the filter plate 1502 can be cleaned. Then, the filter plate 1502 can be disassembled and cleaned at the same time.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
