Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The same or similar reference numerals in the drawings of the present embodiment correspond to the same or similar components; in the description of the present invention, it should be understood that if there are the terms "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, it is only for convenience of description and simplification of the description, but it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore the terms describing the positional relationship in the drawings are only for illustrative purposes and are not to be construed as limitations of the present patent, and those skilled in the art can understand the specific meanings of the terms according to specific situations.

The following describes the implementation of the present invention in detail with reference to specific embodiments.

Fig. 1 to 4 show a conventional battery box structure, in which the sealing surfaces are horizontal surfaces, and due to the horizontal arrangement of the sealing surfaces, wasted space 24 and wasted space 25 are generated, and the wasted space 24 and wasted space 25 cannot be used for placing battery modules, which is a huge waste on a power battery box body with small size, resulting in low utilization rate of the battery box space.

Referring to fig. 5-7, a structure of a battery box with high space utilization according to an embodiment of the present invention is shown, including a battery box body 1 and a sealing cover 2, where the battery box body 1 is provided with a downward accommodating groove 3 with an opening at the top of the battery box body 1, and the sealing cover 2 is used for sealing the accommodating groove 3; the upper part of the outer wall of the battery box body 1 is inwards sunken to form an annular notch 4, and an annular sealing layer 5 is arranged on the side wall of the annular notch 4 in a surrounding mode; the sealing cover 2 comprises a cover plate 6, an annular surrounding dam 7 is arranged on the periphery of the cover plate 6 in a downward protruding mode, and the annular surrounding dam 7 surrounds and wraps the annular sealing layer 5.

According to the battery with high space utilization rate, the battery box body 1 is hermetically connected with the sealing cover 2 through the arrangement of the annular notch 4, the annular sealing layer 5 and the annular surrounding dam 7, so that the effect of preventing moisture from entering the battery box body 1 from the outside is achieved, and the battery module in the battery box body 1 is prevented from being damaged; meanwhile, the sealing mode is realized through the structure, so that the outside of the battery box does not occupy redundant space, and the space utilization rate of the battery box is improved.

Specifically, the sealing layer is a soft sealing glue; the sealing effect of the soft sealing glue is good, and the soft sealing glue is convenient to surround the periphery of the side wall of the annular notch 4 due to certain elasticity, so that the operation is simple and convenient.
