Embodiment

Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described.

Shown in Fig. 1-6, in Fig. 1, can be according to the diameter and the height of the size design monomer cylindrical battery of required battery capacity, battery container and cap are designed to as Fig. 1, Fig. 2 and structure shown in Figure 3: promptly 6 cylinder monomers 3 have symmetrical distribution in the battery container 1, by 2 * 3 dense accumulation mode arrangement design, and the casting processes of routinely battery container.

Two semi arch tubes 4 of housing both sides are to add for the symmetry that keeps the integral battery door housing, then can omit as the symmetry of not considering outward appearance.Because the casting processing technology of conventional battery container be as everyone knows, do not relate to or influence the described battery container design feature of this patent, chat so will not tire out at this.In Fig. 2 and Fig. 3, on 6 center of arc positions on the battery cap 2, be provided with the steam vent 6 of 6 protrusions, 5 grooves 7 on the cap 2 are connected to each other 6 monomer circular arcs 14, reference column 5 plays the role of positioning in the combining of housing and cap, in two binding post holes 8, be with square binding post 10, use for external connection.Decorate first arc tube 4 of semicircle 9 and housing on the cap and match, play the symmetry effect.

Process battery container according to Fig. 1, Fig. 2 and Fig. 3, the assembling of battery can be undertaken by the processing technology of present known conventional, simultaneously the monomer cylindrical battery is connected by shown in Figure 4.In each cell 12, be equipped with the lug 11 that is connected with grid, each cell in the housing coupled together by lug 11 and connector 15.

In making cell process, can adopt conventional glue sealing technology also can adopt conventional heat seal technology to finish being tightly connected between battery container and the cap, form whole column type sealed cell as described in Figure 5.Figure 5 shows that the battery that mounted inside finishes.Top cover 13 covers on cap 2 in Fig. 6, exposes two binding posts 10 using for external connection on the top cover, in said process, can adopt the glue sealing technology of present known conventional, utilizes " epoxide-resin glue " sealing and curing at ambient temperature that is:.Because the utility model relates to the shell structure of column type coiling battery and the connected mode of inside battery, do not relate to the concrete manufacturing process of column type coiling battery, therefore the manufacturing process of coiled battery itself is not narrated at this.

Characteristics of the present utility model are that the single lattice in the battery are designed to column type, and integral battery door is by a plurality of circles Post monomer (cell is pressed dense accumulation) consists of. The cylinder cell is to adopt battery separator negative with one positive one Two pole plate isolation become the column type cell by coiling. The design of the pole plate of column type cell To adopt a plurality of lugs (two or two more than the battery) structure at a slice grid with manufacturing. By adopting letter Single easily cell connected mode makes the electric current distribution of electrode integral even, has improved electrode active The property material utilization ratio also improved simultaneously the efficient of confluxing, when reducing the electrode internal resistance, also prolonged The service life cycle of battery. By adopting coiling and molding technology, cell is prepared into the column type monomer Battery makes electrode integral stressed (pressure) even, has avoided simultaneously the mechanical strength of flat plate cell inadequate, The Swelling and contraction of (because of the variation of electrode active material volume) pole plate decreases easily in exterior vibration and the use procedure The weakness such as evil idea.

In sum, adopt the connected mode of above-mentioned battery case structure and inside battery, can be used for Gao Gong The preparation of rate winding type lead-acid battery.
