Embodiment
Several the improvement that the utility model relates to all on battery cover, so reflected in the accompanying drawings through improved battery cover, have been omitted the other parts such as battery case of storage battery.Referring to Figure 11, battery cover is made up of battery big cover 1 and exhaust cap 2, added electrolyte after, both heat-sealings are for one.Referring to Fig. 1, Fig. 6, storage battery is made of six cells, is provided with six liquid injection holes 9 and six electrolyte return ports 13 on battery big cover.On exhaust cap, be provided with six exhaust posts 20 with electrolyte return port 13 corresponding positions, exhaust cap forms the unit sash with corresponding each cell in battery big cover heat-sealing back, the structure of six sashes is basic identical, is the structure and the effect of example explanation acid baffling clapboard with one of them. Acid baffling clapboard 6 and 7 electrolyte when preventing the storage battery wide-angle tilt is provided with by overflowing in the filter pore 21 on the exhaust cap 2.Referring to Fig. 8, when the relative normal mounting inclined position 90 of storage battery is spent, when promptly being the bottom surface placement (position as shown in Figure 8) with left and right sides face, acid baffling clapboard 6 and 14 is higher than the height of liquid level 25 in the cell separately respectively, therefore, electrolyte can not be crossed acid baffling clapboard and flow to filter pore and outwards overflowing thus by the passage between each sash on the exhaust cap.Referring to Fig. 5, when treating that storage battery is got back to the normal mounting position, be collected at the electrolyte at acid baffling clapboard place, slowly be back in the return port 13 through the backflow gap 24 between acid baffling clapboard and the sash.Referring to Fig. 5, near the inclined-plane the return port 13 is provided with and is beneficial to the electrolyte backflow.The purpose of electrolyte backflow buffer board 8 is set, and is in order to cushion electrolyte flow speed.Be arranged in two sashes at place, exhaust cap two ends, because of being provided with filter pore 21, so acid baffling clapboard only is set, electrolyte backflow buffer board be not set, the position of acid baffling clapboard and electrolyte backflow buffer board is one to one in battery big cover and the exhaust cap.
Referring to Fig. 1, six liquid injection holes 9 sidewall all is positioned on the straight flange 10 on the battery big cover, and the hole wall of each liquid injection hole is contour, also is provided with overflow gap 11,12 on battery big cover.This design can be simplified and add the operating process of filling the electrolyte operation.Behind each cell topping up, with battery and base parallel oblique, unnecessary electrolyte will flow out from liquid injection hole and overflow gap, behind the recovery battery normal position, can guarantee that six liquid levels in the cell are contour, not need manually to adjust liquid level with suction pipe.
Shown in Figure 1, six return ports 13 are positioned at the center line of battery broadside on the battery big cover.This structure can make when storage battery is the bottom surface placement with the two sides, front and back respectively (position as shown in Figure 1) if electrolyte content is less than 1/2nd of capacity in the battery, will not have electrolyte by overflowing in the return port.If electrolyte content is more, then place on the two sides, front and back, and the electrolyte spill-out is consistent, and avoiding in one direction, electrolyte overflows too much.
Referring to Fig. 9, Figure 10, Figure 11, battery big cover is parallel with exhaust cap heat-sealing back upper surface, only leaves a narrow slit between the two.Referring to Fig. 1, Fig. 4, on battery big cover, be provided with a detent 16,5 * 16 millimeters of groove size.This groove is the usefulness of putting the locating piece in the positioning tool when aiming at exhaust cap and battery big cover heat-sealing.In former design, there is not this groove, lack the space, location, only locate on the Width during exhaust cap heat-sealing on one side near the handle axle, the inaccurate hidden danger in location is arranged.Can realize bilateral location after the improvement, solve the problems referred to above.
Referring to Fig. 9, Fig. 1, Fig. 2, Fig. 3, on battery big cover, also be provided with handle card platform 15, two Ka Tai made handle produce micro-strain when handle 3 kept flat, and thus fixedly handle keep flat the position.Handle axle 4 is to be the usefulness of installation handle, and it is a hollow structure, and its axis hole is made of two up-small and down-big half-cylindrical holes.This structure one is to prevent handle beam warp heat-sealing operation after-contraction distortion (solid construction easily shrinks distortion), influences the quality of fit of handle axle and handle aperture; The 2nd, can guarantee that the handle axle has enough strength support handles and lifts storage battery.When two handles 3 keep flat, support skewback 22 by symmetrically arranged handle respectively and support, leave between two skewbacks and lift spacing 23, this spacing feeds to the usefulness that lifts handle.
