[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a normally open high-voltage battery pack charger, including a charger housing 1, a mounting block 2 fixedly connected to the top of the charger housing 1, two indicator lights 3 fixedly connected to the top of the mounting block 2, an interface 5 fixedly connected to one end of the charger housing 1, multiple heat dissipation holes 4 opened on the top of the charger housing 1, a mounting opening 6 opened on the outside of the charger housing 1, a filter screen 7 fixedly connected inside the mounting opening 6, a mounting plate 8 fixedly connected inside the charger housing 1, a cooling fan 9 fixedly connected to the outside of the mounting plate 8, and a wire 10 fixedly connected to the other end of the charger housing 1, the wire 10 being away from... A plug 11 is fixedly connected to one end of the charger housing 1. A storage mechanism 12 is provided on the outside of the charger housing 1. When in use, the product to be charged can be connected through the interface 5. Pulling the plug 11 causes the wire 10 to extend out of the storage mechanism 12. The plug 11 is inserted into the socket. During charging, one of the two indicator lights 3 on the mounting block 2 lights up red. The cooling fan 9 rotates and works with the heat dissipation hole 4 to dissipate heat. The filter screen 7 can prevent the cooling fan 9 from sucking external dust into the charger housing 1. After charging is completed, the other indicator light 3 on the mounting block 2 lights up green to indicate to the user that charging is complete.

[0022] The storage mechanism 12 includes a housing 120, which is fixedly connected to the outside of the charger housing 1. A cover plate 121 is hinged to the top of the housing 120. A locking block 122 is fixedly connected to the outside of the cover plate 121. Two fixing blocks 123 are fixedly connected to the outside of the housing 120. A mounting shell 124 is fixedly connected to the outside of the fixing blocks 123. A slider 125 is slidably connected inside the mounting shell 124. A plug rod 126 is fixedly connected to one side of the slider 125. A connecting block 127 is fixedly connected to the top of the plug rod 126. A spring 128 is installed inside the mounting shell 124. A rotating rod 129 is rotatably connected inside the housing 120. A spring-loaded spring 1210 is fixedly connected to the outer periphery of the housing 120. A limit plate 1211 is fixedly connected inside the housing 120. In use, pulling the plug 11 drives the wire 10 from the outside. The wire 10 extends out of the housing 120, driving the rotating rod 129 to rotate. The rotating rod 129 drives the spring 1210, causing the spring 1210 to wind up and generate elastic force. When the wire 10 needs to be inspected or maintained, the connecting block 127 is pushed, and the connecting block 127 slides inside the mounting housing 124. The connecting block 127 drives the slider 125 to slide inside the mounting housing 124. The slider 125 drives the insertion rod 126 to slide out from inside the locking block 122 and the fixing block 123. At the same time, the slider 125 compresses the spring 128, causing the spring 128 to generate elastic force. At this time, the cover plate 121 can be opened to inspect and maintain the wire 10 inside the housing 120. When storing the wire 10, the wire 10 is gently pushed into the housing 120, and the spring 1210 drives the rotating rod 129 to wind up the wire 10.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a normally open high-voltage battery pack charger, including a wire 10 slidably connected to the outside of a housing 120, allowing the wire 10 to be stored and pulled out; the outer periphery of the wire 10 is fixedly connected to the outer periphery of a rotating rod 129, allowing the wire 10 to be stored by the rotating rod 129; a locking block 122 slidably connected to the outside of two fixing blocks 123, allowing the locking block 122 and the fixing blocks 123 to engage; a connecting block 127 slidably connected to the outside of a mounting shell 124, allowing the connecting block 127 to be pushed; and a plug rod 126 slidably connected to the outside of the mounting shell 124. Inside, the insertion rod 126 can extend and retract. The outer side of the insertion rod 126 passes through the fixing block 123 and is inserted into the inside of the locking block 122, so that the cover plate 121 can be stably closed. One end of the spring 128 is fixedly connected to the outer side of the slider 125, and the other end of the spring 128 is fixedly connected to the inner wall of the mounting shell 124, so that the spring 128 can be compressed by the slider 125 to generate elastic force. The outer circumference of the rotating rod 129 is rotatably connected to the inside of the limiting plate 1211, so that the rotating rod 129 can rotate stably. The end of the spring 1210 away from the rotating rod 129 is fixedly connected to the inner wall of the outer shell 120, so that the spring 1210 is stably installed.
