Problems solved by technology
On the one hand, when the heat-sealed edges around the large and small covers are melted, excessive heat-melting is likely to occur, and the small cover will press the safety valve, and the safety valve cannot be opened normally, resulting in the gas inside the battery not being discharged, which may cause battery failure. Explosion will reduce the safety of the battery; on the other hand, the middle part of the auxiliary battery cover is hollow, and the impact resistance is poor

Embodiment Construction
[0029] figure 1 , 2 In 3, there is a circle of heat-sealing ribs 5 inside the edge of the rectangular small cover 1 . The heat-sealing ribs 5 include two horizontal heat-sealing ribs arranged along the length direction of the small cover 1, and two connecting heat-sealing ribs connected between the two horizontal heat-sealing ribs. Vertical heat-seal ribs, arc-shaped heat-seal ribs connected with vertical heat-seal ribs, the ends of two arc-shaped heat-seal ribs are connected with the end of one horizontal heat-seal rib, and the two vertical heat-seal ribs are connected with the middle of another horizontal heat-seal rib , The air filter sheet 9 is installed in the air filter sheet installation hole 7, and the air filter sheet installation hole 7 communicates with the exhaust passage 6. The exhaust channel 6 is connected by a low channel 61 placed on the inside and a high channel 62 placed on the outside to form a stepped structure. The low channel 61 is located at the lower...

The invention provides a safety auxiliary battery cover, which comprises a cover body, wherein the cover body comprises a large cover and a small cover, the large cover is divided into a small cover area and a terminal area from the middle in the length direction, the small cover area is provided with a circle of heat sealing edge matched with the small cover for heat sealing, a limiting column, apositioning column and a plurality of first reinforcing ribs are arranged in the middle of the small cover area, a positioning hole matched with the positioning column and a plurality of second reinforcing ribs are arranged on the small cover, when the small cover and the large cover are subjected to heat sealing, the positioning column is installed in the positioning hole, and the ends of the first reinforcing ribs and the ends of second reinforcing ribs make contact and are subjected to hot melting to form a complete reinforcing rib, an air filtering sheet is arranged at an air filtering sheet mounting hole, the air filtering sheet mounting hole is communicated with an exhaust channel, the exhaust channel is of a step-shaped structure formed by connecting a low channel arranged on the inner side and a high channel arranged on the outer side, the low channel is located on the lower portion of the vertical heat sealing rib, the edge of the small cover is provided with an orifice of the high channel, and the orifice is circular. According to the invention, the shape of the opening of the exhaust hole meets the national standard, the space of an exhaust channel is enlarged, safety is high, and impact resistance is high.
Description
technical field [0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to a small cover for an auxiliary battery. Background technique [0002] Under the general trend of increasingly stringent fuel standards, major automakers at home and abroad are constantly developing new energy-saving and environmental protection technologies to meet local environmental protection requirements. Among various energy-saving and environmental protection technologies, the popularity and use of start-stop systems and plug-in hybrid electric vehicles are increasing. It has rapidly covered economical and energy-saving models from the earliest high-end models such as BMW, Mercedes-Benz and Audi. It is expected that by 2020, More than 40% of new cars in the Chinese market will be equipped with start-stop systems, hybrids or plug-in hybrids. [0003] The start-stop system is based on the addition of an automatic start-stop motor on the basis of a tra...
