Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides Figures 1 to 8 The waterproof PACK device based on the soft-pack battery cell shown in the figure includes an outer shell 1 and a soft-pack battery cell module 2. The outer side of the soft-pack battery cell module 2 is installed with an inner shell 3. The soft-pack battery cell module 2 and the inner shell 3 are both arranged in the inner cavity of the outer shell 1. A movable component 4 for positioning the soft-pack battery cell module 2 is arranged between the inner shell 3 and the outer shell 1. A limiting component 5 is installed on the top of the inner cavity of the outer shell 1. The limiting component 5 is in contact with the top of the soft-pack battery cell module 2. A waterproof mechanism 6 is installed on the top of the outer shell 1 to provide a waterproof seal for the soft-pack battery cell module 2. The waterproof mechanism 6 is in contact with the outer shell 1. The shells 1 are connected by a fixing mechanism 7. The inner shell 3 and the outer shell 1 are provided to increase the waterproof effect of the soft-pack battery module 2, and the soft-pack battery module 2 is installed in the inner shell 3, wherein there is no direct connection between the inner shell 3 and the outer shell 1, thereby forming an air cavity, and the waterproof mechanism 6 is provided on the top of the outer shell 1, which enhances the waterproof effect of the outer shell 1, thereby providing protection for the internal soft-pack battery module 2, extending the service life of the soft-pack battery module 2, and avoiding the problem of damage to the soft-pack battery module 2 due to moisture.

[0027] The waterproof mechanism 6 includes a sealing cover 61. A first groove opening 62 is provided around the sealing cover 61 on the side facing the outer shell 1. A second groove opening 63 is provided around the top of the outer shell 1 at a position corresponding to the first groove opening 62. A waterproof strip 64 is provided between the first groove opening 62 and the second groove opening 63. The sealing cover 61 and the outer shell 1 are connected by a fixing mechanism 7. The first groove opening 62 and the second groove opening 63 can facilitate the installation of the waterproof strip 64. Then, the connection between the sealing cover 61 and the outer shell 1 is sealed to seal the gap between the sealing cover 61 and the outer shell 1, thereby enhancing the waterproof effect of the PACK device.

[0028] The fixing mechanism 7 includes fixing bolts 71 and fixing blocks 72. The four fixing blocks 72 are fixed at the corners of the inner cavity of the shell 1. Insertion grooves 73 are provided around the surface of the sealing cover 61. The fixing bolts 71 are inserted into the insertion grooves 73. The bottom of the fixing bolts 71 is threadedly connected to the fixing blocks 72. A waterproof pad 74 is sleeved at the connection between the insertion groove 73 and the fixing bolt 71. The sealing cover 61 can be fixed to the shell 1 by the set fixing bolts 71 and the fixing blocks 72 to prevent the sealing cover 61 from detaching from the shell 1. At the same time, the waterproof pad 74 can be used to waterproof the position of the insertion groove 73 used by the fixing bolt 71.

The insulating plate 54 is in contact with the upper surface of the soft-pack battery module 2, which can provide a limit for the inner shell 3 and the soft-pack battery module 2, so that the soft-pack battery module 2 and the inner shell 3 do not change their position in the outer shell 1, thereby enhancing the stability of the installation of the soft-pack battery module 2.

[0031] Support frames 8 are fixedly connected to both sides of the surface of the shell 1, and through holes 9 are opened on the support frames 8 at equal distances. Mounting seats 10 used in conjunction with the through holes 9 are installed on the tops of both ends of the support frames 8, which can provide isolation for the installation position of the shell 1 and other objects, and at the same time facilitate the staff to install and fix the shell 1.

[0032] The edges around the outer shell 1 are set as beveled surfaces, and an air cavity is formed between the inner shell 3 and the outer shell 1 through the movable component 4. The formed air cavity avoids direct contact between the inner shell 3 and the outer shell 1, and the edges of the outer shell 1 are set with beveled surfaces to reduce scratches with staff.

[0033] During specific use, the soft-pack battery module 2 is first installed in the inner shell 3, and then the soft-pack battery module 2 is installed inside the outer shell 1 through the slide 42 and the slider 41 in the movable component 4, and an air cavity is formed between the outer shell 1 and the inner shell 3, thereby avoiding contact and connection between the outer shell 1 and the inner shell 3, and improving the waterproof and moisture protection of the soft-pack battery module 2. Subsequently, the waterproof strip 64 is installed inside the first groove 62 and the second groove 63 between the outer shell 1 and the sealing cover 61, sealing the gap at the connection between the sealing cover 61 and the outer shell 1, thereby enhancing the waterproof effect of the PACK device. Then, the sealing cover 61 can be fixed to the outer shell 1 through the fixing bolt 71 and the fixing block 72 in the fixing mechanism 7 to prevent the sealing cover 61 from detaching from the outer shell 1. At the same time, the waterproof pad 74 can be used to waterproof the position of the plug-in slot 73 used by the fixing bolt 71, thereby completing the waterproof work of the PACK device, so that the soft-pack battery module 2 is better protected and the problem of damage to the soft-pack battery module 2 due to moisture and water seepage is avoided.
