DETAILED DESCRIPTION

[0022] The embodiment of the utility model will be described in detail below in combination with the drawings, but the utility model can be implemented according to the multiple different ways of claim limitation and coverage.

[0023] Embodiment:

[0024] Referring to Figure 1 A battery box comprises a battery box body 2 and a box door structure 1; the battery box body 2 comprises an outer shell 2.1 and a containing cavity for containing batteries, and the outer shell 2.1 is provided with a box door mounting port for mounting the box door structure 1 and an air outlet. An air outlet cover 3 is arranged outside the air outlet; the air outlet and the box door mounting port are arranged in a staggered manner. Air can enter the battery box through the air inlet of the box door structure 1 and be discharged through the air outlet of the air outlet cover 3.

[0025] Referring to Figures 2-4 The box door structure 1 comprises a box door body 1.1, a box door outer plate 1.2, a first filter 1.3 and a second filter 1.4; the box door outer plate 1.2 is provided with a first air inlet 1.2.1, and the lower end of the first air inlet 1.2.1 is provided with a residue discharge port; the first filter 1.3 is arranged on the outer side of the box door body 1.1 and is detachably arranged on the box door body 1.1 through the box door outer plate 1.2; the box door body 1.1 is provided with a second air inlet 1.1.1, and air entering from the first air inlet 1.2.1 passes through the first filter 1.3 and then enters through the second air inlet 1.1.1; the second filter 1.4 is detachably arranged on the inner side of the box door body 1.1 through a filter support frame 1.5, and air entering through the second air inlet 1.1.1 is filtered after passing through the second filter 1.4. The filter support frame 1.5 is provided with a containing cavity for placing the second filter 1.4, and the filter support frame 1.5 is detachably arranged on the box door body 1.1 through a baffle 1.6. Specifically as follows:

[0026] The filter support frame 1.5 is riveted to the back of the box door body 1.1, the second filter 1.4 is made of 40PPI polyurethane filter cotton, directly placed in the containing cavity of the filter support frame 1.5, the baffle 1.6 is installed on the filter support frame 1.5 by using bolts, the second filter 1.4 is pressed in the filter support frame 1.5 to be fixed, and the second filter 1.4 and the second air inlet 1.1.1 are arranged correspondingly to ensure that air passing through the second air inlet is filtered by the second filter. The edge of the second filter 1.4 can also be glued to enhance the fixation or a sealing ring can be additionally arranged for sealing.

[0027] The box door body 1.1 is provided with a second air inlet 1.1.1, which is a horizontal long strip air inlet; the front surface of the box door outer plate 1.2 is provided with a first air inlet 1.2.1, which is a vertical long strip air inlet and has a lower opening (i.e. a residue discharge opening). The first air inlet and the second air inlet are completely staggered, so that when rain, sand and other foreign matters enter the vertical long strip air inlet on the front surface of the box door outer plate 1.2, they can be discharged through the lower opening (i.e. the residue discharge opening) of the box door outer plate 1.2.

[0028] The first filter 1.3 is a 30-mesh stainless steel filter screen, which is riveted to the front surface of the box door body 1.1 and is treated with sealing glue around the periphery to enhance the dustproof effect. The box door outer plate 1.2 is riveted to the front surface of the box door body 1.1 and is treated with sealing glue around the periphery to enhance the dustproof effect.

[0029] The vertical air inlet of the box door outer plate 1.2 and the horizontal air inlet of the box door body 1.1 are different in height and position, so that foreign matters cannot directly impact the horizontal air inlet of the box door body 1.1 and rain cannot directly enter the box body, which has a good protective effect.

[0030] In actual use, the specific air flow path is as follows: ① air flows into the first air inlet 1.2.1 (i.e. the vertical air inlet) of the box door outer plate 1.2, and the first air inlet 1.2.1 prevents large foreign matters from entering; ② the air flowing into the first air inlet 1.2.1 is filtered again by the first filter 1.3 (i.e. the filter screen) to prevent foreign matters from entering through the box door outer plate; ③ the air filtered for the second time flows into the second air inlet 1.1.1 (i.e. the horizontal long strip air inlet) on the box door body 1.1, and is filtered for the third time by the second filter 1.4 (i.e. the filter cotton) before entering the containing cavity of the battery box body 2 in which the storage battery is placed, so as to prevent dust from entering; ④ the air after ventilating the storage battery flows out through the air outlet cover 3 on the outer shell 2.1 of the battery box body 2.

[0031] It can be seen that the battery box body of the embodiment is used, and the air flow is filtered for three times from entering to flowing out, which greatly improves the dustproof effect and ensures the ventilation quality of the storage battery.

[0032] In addition, after being used for a period of time, the second filter 1.4 can be removed from the box door structure 1 for replacement, and the first filter 1.3 can also be effectively cleaned.

[0033] The above only describes preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
