Description of the Invention: [Technical Field] The present invention relates to a battery can structure of a secondary battery, and more particularly to an outer structural design of a can of a battery can. [Prior Art] In the battery can design of a conventional secondary battery, whether it is a square or a shape of a can body, the outside of the battery can is usually thin. When used for a power battery, a plurality of batteries are usually used. Tank 2, 俾 can provide a relatively large power output; stack multiple battery cans' For a square battery, it has multiple planes for stacking ^ no stacking but for round cans In other words, there is no two direct stacking. As shown in Fig. 1, a plurality of conventional circular battery cans 10 are connected and used. Loose and easy to manage centrally, it will be used as a centralized assembly method for battery cans 10 through straps, straps 11 or frames; it is worth noting that multiple round cans can be used through tapes, straps or frames. For centralized connection, however, if the battery is concentrated by tape or band, if one of the battery cans is to be taken out or other battery cans are added, the entire battery combination must be disassembled and then reassembled, and then bundled. With a combination of several battery cans, if Under the external force, Lai Cheng, the battery can be relatively displaced between each other, the overall instability (such as the offset state shown in the first figure); and if the frame is used as a centralized setting of the battery can, increase or decrease the battery can The quantity must be consistent with the use of the corresponding framework, otherwise there will be disadvantages of insufficient use or waste of space; as can be seen from the above description, the battery can structure of the conventional secondary battery, especially the circular battery canister, performs multiple batteries. When the combination of the tanks is used, there is a problem that the combination of the plurality of battery cans is difficult; therefore, the inventor of the present invention has a simple structural design, so that it can be easily and firmly combined, and the solution can be solved if the battery can be considered. The predicament of the conventional structure when the external combination of multiple battery cans is performed. SUMMARY OF THE INVENTION The main purpose of the present month is to provide a battery can structure of a secondary battery, which is mainly composed of a plurality of rib structures protruding from the outside of the can body of the battery can, thereby When the tank bodies are used in the joint connection, the ribs of the adjacent tank bodies are just embedded with the recesses of the adjacent tank bodies, and the adjacent tank bodies are allowed to pass through the ribs and the recesses. Embedding (toothed) and pinching the solid, and p: single to carry out the beam cooperation, the relationship between the various will not arbitrarily roll or separate. Another object of the present month is to provide a battery can structure 4 for a secondary battery. The invention has a convex _ structure design on the outside of the can body, and the rib structure has a Wei which increases the lion degree of the can body, and the rib can be regarded as a structure. Ribs, when the tank body is subjected to external force, the convex material can be damaged by the depression or large deformation of the tank body. [Embodiment] The present invention has been made in accordance with the techniques, means and functions of the present invention, and a preferred embodiment is described in detail with reference to the drawings. First, please refer to Figures 2, 3 and 4 As shown in the embodiment of the present invention, a battery can structure of a secondary battery is mainly composed of a can body 1333704 of the battery can. The external convex body is formed by a plurality of rib structures; wherein: the can body 20 is The utility model has a cylindrical structure, and the inside can be accommodated by a battery component such as a pole coil 301, a gasket 302, etc., and the two ends of the can body 2 can be respectively provided with a cover 21 on the outer wall of the can body 20. Continuously projecting a plurality of rib 22 structures ' and each of the ribs 22 is separated by a recess 23 equidistant from the width of the rib 22; if a plurality of cans 2 are adjacent to each other, The ribs 22 of the adjacent can bodies 20 are disposed in the recesses 23 of the adjacent can bodies 2〇. φ above is the structure of the present invention and its relationship position. Through the structural design of the present invention, when a plurality of battery cans are used in a snap-fit connection, the adjacent battery cans are transmitted through adjacent convexities. The rib 22 and the recess 23 are embedded with each other; the state of use thereof will be described in detail as follows: Referring to Figures 3 and 4, the present invention is particularly formed by forming a plurality of outer wall faces of the can body 2〇. The structure of the rib 22 is formed and a recess 23 is formed between the adjacent ribs 22 so that the outer wall surface of the can 2 is formed like a gear; when a plurality of can bodies 20 are When the snap-fit connection is used, the ribs 22' of the adjacent can bodies 20 are just embedded with the recesses 23 of the adjacent can bodies 20, that is, the ribs 22 are located in the recesses 23; Between the adjacent can bodies 2, the ribs 22 and the recesses 23 are inserted and fixed (toothed), and the cans are not arbitrarily rolled as long as the bundle is simple. Or separation, for example, as shown in the fourth figure, that is, four batteries of the present invention ν5> ι 1333704 ' The cans are directly oscillated by the ribs 22 and the recesses 22 directly outside the can bodies 20, and then passed through a bundle 40 for use, whereby the can bodies 20 are not arbitrarily rolled or In addition, the structural design of the rib 22 provided on the outside of the can body 2 by the present invention can not only perform a combination of a plurality of battery cans 2, but the structure of the rib 22 further increases the structural strength of the can 20 In other words, the rib 22 can be regarded as a structural rib. When the can body 20 is impacted by an external force, the design of the rib 22 can prevent the can body 20 from being sunken or greatly deformed and damaged; The width distance of each concave space may be a width distance corresponding to the width of the convex ribs, except for the width distance corresponding to the convex ribs (not shown, because the distance difference is relatively small, it is difficult to display through the pattern). Therefore, it is possible to avoid the practical problem that the rib can not be immersed in the concave cavity; it is worth mentioning that the above-mentioned continuous outer wall of the can body is provided with a plurality of ribs and a hollow structure. In practice, it can also be as shown in Figure 6. After the outer portion of the can body 20a is separated by at least one blank block 24, the structure of the plurality of ribs 22a is formed by re-joining, and the ribs 22a are separated from each other by a width of the rib 22a. The distance between the recesses 23a', thereby the plurality of battery cans can still be connected to the toothed assembly, wherein the zero of the blank block 24 can be used to effectively reduce the overall weight and material cost, otherwise Referring to Fig. 7, when a plurality of battery cans are used for assembly, the blank block 8 24 can be located at a non-adjacent portion of each object 2〇a, so that there is no problem that affects the connection.
