[0044] The battery module is usually installed in the battery box, and the battery box needs to have a certain sealing performance to prevent water or dust from entering the battery box. In some vehicles, the traditional battery pack structure is omitted from the battery box, and the battery module is directly arranged on a frame and installed on the vehicle frame structure through the frame to simplify the structure. Among them, the bottom of the battery box is arranged by several battery modules in sequence along the horizontal direction, and there are the following two problems: one is that the sealing effect between adjacent battery modules is poor, and the other is that the sealing effect between the battery module and the frame is poor, resulting in water or dust being easily introduced into the battery box.

[0045] To solve the above problems, this embodiment provides a battery box to solve the problems in the prior art that the sealing effect between adjacent battery modules is poor, and the sealing effect between the battery module and the frame is poor, resulting in water or dust being easily introduced into the battery box.

The bottom battery module group 2 includes a plurality of bottom battery modules 21 arranged in sequence along the horizontal direction. Any two adjacent bottom battery modules 21 are connected by a first seal 3. The first seal 3 includes a first seal structure provided on one of the bottom battery modules 21 and a second seal structure provided on the other bottom battery module 21. The first seal structure and the second seal structure cooperate with each other to form a seal, thereby realizing the seal between two adjacent bottom battery modules 21. This battery box can simultaneously seal between the bottom battery module group 2 and the box body frame 1 and between two adjacent bottom battery modules 21, thereby improving the sealing performance of the battery box.

[0047] Continue to refer to Figures 1-10 , among any two adjacent bottom battery modules 21, the first seal structure is a first seal protrusion 31 protruding from one of the bottom battery modules 21, and the second seal structure is a first groove 32 opened in the other bottom battery module 21. The first seal protrusion 31 is inserted into the first groove 32, that is, the first seal 3 is the first seal protrusion 31 protruding from one of the bottom battery modules 21 and the first groove 32 opened in the other bottom battery module 21. The installation and sealing are realized through the insertion fit between the first seal protrusion 31 and the first groove 32.

[0048] In other embodiments, the first seal 3 can also be a sealing strip provided on one of the bottom battery modules 21, and the sealing strip is attached to the other bottom battery module 21 to form a seal.

The installation and sealing are achieved through the insertion fit between the second sealing protrusion 51 and the second groove 52.

[0054] In other embodiments, the second seal 5 may also be a sealing strip disposed on one of the middle battery modules 41, and the sealing strip is attached to the other middle battery module 41 to form a seal.

[0055] Optionally, the cross-section of the second sealing protrusion 51 is triangular, rectangular or L-shaped, and the shape of the second groove 52 is adapted to that of the second sealing protrusion 51, so that the outer wall of the second sealing protrusion 51 fits against the inner wall of the second groove 52 to achieve a better sealing effect.

Specifically, a plurality of support blocks 12 are arranged on the box frame 1 in the vertical direction, and the plurality of middle battery module groups 4 are respectively supported on the plurality of support blocks 12. Optionally, since the plurality of middle battery module groups 4 are arranged at intervals, in order to prevent water or dust from entering through the gap between adjacent middle battery module groups 4, the battery box further includes a guard plate 8, and a guard plate 8 is arranged between any two adjacent middle battery module groups 4, and a guard plate 8 is also arranged between the bottom battery module group 2 and the lowermost middle battery module group 4.

[0057] Continue to refer to Figures 1-10 , a top plate 6 is arranged on the top of the box frame 1, and a side plate 7 is arranged on any side surface of the box frame 1, so as to provide protection for the top and side parts of the battery box and prevent water or dust from entering the battery box.

[0058] Continue to refer to Figures 1-10 , a top plate sealing strip 61 is arranged between the top plate 6 and the box frame 1 to enhance the sealing performance between the top plate 6 and the box frame 1; and / or, a side plate sealing strip 71 is arranged between the side plate 7 and the box frame 1 to enhance the sealing performance between the side plate 7 and the box frame 1. This embodiment exemplarily gives a solution of simultaneously arranging the top plate sealing strip 61 and the side plate sealing strip 71.

[0059] This embodiment also provides a vehicle, which includes the above battery box and a vehicle frame, and the battery box is arranged on the vehicle frame.
