[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] like Figures 1 to 8 As shown, this embodiment proposes a new energy vehicle battery bracket structure, including a bottom shell 1, an upper cover 2, a connecting frame 3, a locking assembly 4, a baffle 5, a limiting mechanism 6, a jack 11, a slot 12 and a mounting hole 13 opened on the upper side of the connecting frame 3.

[0039] Among them, the interior of the aluminum bottom shell 1 is divided into several troughs by several horizontal partitions and one vertical partition for holding battery packs as battery compartments 7. Heat dissipation slots 8 are opened on the outer side of the bottom shell 1 along the direction of the horizontal partitions. Several evenly distributed X-shaped reinforcing ribs 9 are arranged inside the heat dissipation slots 8. While ensuring that the heat is conveniently dissipated outward between the inner battery compartments 7, the overall strength of the bottom shell 1 is ensured. An upper cover 2 is arranged on the upper side of the outer side of the bottom shell 1. Several evenly distributed heat dissipation fins 10 are fixedly connected to the upper side of the upper cover 2. The lower side of the upper cover 2 is a heat conducting sheet to enhance the heat dissipation of the battery pack. A sealing ring 17 is fixedly connected to the lower side of the upper cover 2. A sealing groove 16 used in conjunction with the sealing ring 17 is opened on the upper side of the outer side of the bottom shell 1 to enhance the sealing between the upper cover 2 and the bottom shell 1 and to prevent dust and water from entering the battery pack inside the bottom shell 1.

[0040] A connecting frame 3 is fixedly connected to both sides of the outer upper end of the bottom shell 1, and a slot 12 for matching with the upper cover 2 is provided on the lower side of the connecting frame 3, so as to facilitate the engagement of the edges on both sides of the outer upper end of the upper cover 2. A plurality of evenly distributed plug holes 11 are provided on both sides of the upper end of the upper cover 2, and a plurality of evenly distributed locking rods 401 for matching with the plug holes 11 are provided on the lower side of the slots 12. A movable rod 402 is fixedly connected to the upper end of the locking rod 401, and the movable rod 402 can slide up and down inside the plurality of evenly distributed mounting holes 13 provided on the outer upper end of the connecting frame 3. The movable rod 402 is slightly thicker than the locking rod 401. After the movable rod 402 can insert the locking rod 401 into the inside of the socket 11 of the upper cover 2, the upper cover 2 can be pushed downward to assist in the alignment between the upper cover 2 and the bottom shell 1. A baffle 403 is provided on the lower side of the inner part of the connecting frame 3. The baffle 403 and the movable rod 402 are fixedly connected together, and an extrusion spring 404 is provided inside the connecting frame 3. The extrusion spring 404 is sleeved on the movable rod 402. The extrusion spring 404 is between the inner top of the connecting frame 3 and the baffle 403 to always squeeze the baffle 403 downward.

[0041] A connecting plate 405 is provided on the upper side of the outside of the connecting frame 3, and the lower side of the connecting plate 405 is fixedly connected to the upper end of the movable rod 402, so as to facilitate the simultaneous upward and downward movement of the movable rod 402. A baffle plate 5 is provided on the upper side of the inside of the slot 12, and a plurality of evenly distributed adjustment holes 14 for matching the locking rod 401 and the movable rod 402 are provided on the upper side of the baffle plate 5. The front side of the inside of the adjustment hole 14 is a larger circle, which matches the movable rod 402, and the rear side is a smaller circle, which matches the locking rod 401. To match, when the smaller hole of the baffle 5 is aligned with the locking rod 401, the connecting plate 405 is pulled upward, and the bottom end of the movable rod 402 will be blocked by the adjusting hole 14, and the locking rod 401 cannot extend into the interior of the socket 11. When the adjusting hole 14 moves backward and the large hole of the adjusting hole 14 is aligned with the locking rod 401, the movable rod 402 squeezes the baffle 403 through the squeezing spring 404, and the movable rod 402 extends into the interior of the adjusting hole 14, and the locking rod 401 is inserted into the interior of the socket 11, thereby realizing the alignment of the upper cover 2 and the bottom shell 1.

[0042] Embodiment 2:

[0043] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0044] In order to prevent the baffle 5 from escaping from the inside of the slot 12 and to ensure that the baffle 5 can only move forward and backward, limit grooves 602 are opened on both sides of the baffle 5, and limit bars 601 are fixedly connected on both sides of the inside of the slot 12 to ensure that the baffle 5 can only move forward and backward in the inside of the slot 12 along the limit bars 601 through the limit grooves 602. A stopper 15 is fixedly connected to the rear side of the lower side of the baffle 5. When the upper cover 2 moves backward from the inside of the slot 12 and is inserted into the inside of the slot 12, the upper cover 2 can push the baffle 5 through the stopper 15, so that the locking rod 401 can automatically move downward and be inserted into the inside of the hole 11.
