Compared with two same-side pole terminals used at present, utility model has the following advantages that the two guiding pole terminals can enable running paths of Li ions of a positive pole to pass through the integral pole pieces in the charge and discharge process of a battery, all the parts of the pole pieces are sufficiently utilized, the service life of the pole pieces is prolonged, and the charge and discharge effect of the battery is enhanced.
Description
[technical field]
The utility model belongs to battery of electric vehicle manufacturing technology field.
[background technology]
Electric motor car is a kind of not only laborsaving but also the vehicles efficiently, is subjected to liking very much of user.Be again a kind of vehicles of environmental protection because of electric motor car, along with the generally enhancing of social enviroment protection consciousness, electric motor car is more and more universal, and the electric motor car industry also is subjected to government department ground and supports energetically.
Also must satisfy the supporting demand in market of electric motor car as the battery of electric motor car power source, battery is electric motor car " heart ", and the performance of battery directly has influence on the performance and the quality of electric motor car.The structure of existing battery is as follows: it comprises battery case, battery case is extremely important parts in the battery structure, it is cuboid, in a lateral opening, the internal part of battery case is inserted by this opening, and this opening is sealed by lid, and lid is provided with the pair of aluminum pole, two aluminium poles link to each other with same pole piece in placing battery case, two aluminium poles protrude from outer section of lid each link to each other with a bus.There is following defective in existing battery structure.Two pole leading-out ends are in same direction, promptly all are located on the battery lid.And at battery in charge and discharge process, anodal Li ion is only by pole piece one part, because normally be route with the shortest path as a material motion of ion or electronics.Therefore, when two poles were in same direction, the path of ion operation was normally on the top of pole piece, and seldom entered the lower part of pole piece.Like this, only some in running order pole piece is not only aging easily, reduces useful life, and influences the effect that discharges and recharges of battery.
[summary of the invention]
The utility model discloses a kind of two-way battery structure of drawing pole, it has solved existing battery in charge and discharge process, and anodal Li ion only causes useful life of reducing pole piece and the technical problem that influences the battery charging and discharging effect by the part of pole piece.
For solving the problems of the technologies described above, technical solution adopted in the utility model: two-way battery structure of drawing pole, comprise battery case, be cuboid, outer wall forms reinforcement around the battery case, and pole piece is inserted in battery case inside, the top and bottom of battery case all form opening, each is sealed upper and lower opening by a fixed cap, aluminium pole of fixed cap setting-in, and the inside and outside of aluminium pole links to each other with pole piece, bus respectively.
Described battery structure is lined with O type circle between aluminium pole and fixed cap.
Described battery structure, a lateral wall of battery case forms positioning convex point, and another sidewall relative with this sidewall forms corresponding positioning hole, and when two battery cases were assembled mutually, the positioning convex point of the first battery case sidewall embedded the location hole of the second battery case sidewall.
Described battery structure, two adjacent sidewalls of battery case are all laid positioning convex point, and the in addition two side relative with this two adjacent sidewall forms corresponding positioning hole.
Described battery structure, positioning convex point and location hole are respectively established six, and six positioning convex points and location hole are evenly distributed from top to down by triplex row two row.
Battery of the present utility model forms opening in the two relative side of battery case, the symmetrical configuration setting of this two opening part, each opening is respectively drawn a pole. like this, two poles draw the two ends that direction is in pole piece respectively, compare with homonymy two poles of present use, it has following advantage: draw pole for two and can make battery in charge and discharge process, the operating path of anodal Li ion is through whole pole piece, the each several part of pole piece is fully used, prolong the useful life of pole piece, and strengthened the effect that discharges and recharges of battery.
In addition, sealing of current battery box all is at the pole outlet, and it exists the tapering that produces because of plastic deformation to make the pond difficulty of discharging from top to bottom like this, easily with unfavorable factors such as pole piece fracture.And draw by both direction at pole of the present utility model two, and sealing of battery case can be in the side, but not two openings.Like this, owing to seal greatly, it is also easy to put into battery, and also frangibility not of pole piece, has solved above-mentioned technical problem fully.

Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is a three-dimensional structure diagram of the present utility model.
Fig. 3 is plan structure figure of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is elaborated.
As Figure 1-3, battery structure of the present utility model comprises battery case 1, and this battery case 1 is cuboid, and outer wall forms the reinforcement 9 of laterally evenly arranging around it, to strengthen the intensity of battery case 1.
The top and bottom of battery case 1 are opening all, and each modular construction of two opening parts is symmetrical arranged, and the modular construction with the below opening part is that example elaborates to battery structure below.The end opening of battery case 1 is by fixed cap 3 sealings, and the middle part of fixed cap 3 fixedly mounts an aluminium pole 5, and 3 of this aluminium pole 5 and fixed caps are lined with O type circle 8, and the aluminium pole 5 that is in battery case 1 inside links to each other with pole piece 10.The outside of aluminium pole 5 is by rivet 4 fixedly connected buss 2.The end opening snapping removable cover 7 of battery case 1, removable cover 7 covers aluminium pole and one section bus being in the battery case opening part.
Like this, two aluminium poles of battery divide both direction to draw from two of battery case respectively, thereby can make battery in charge and discharge process, the operating path of anodal Li ion is through whole pole piece, the each several part of pole piece is fully used, prolong the useful life of pole piece, and strengthened the effect that discharges and recharges of battery.
Two adjacent lateral walls of battery case 1 form positioning convex point 6, and the positioning convex point 6 of each sidewall is established six altogether, and six positioning convex points are evenly distributed from top to down by triplex row two row.The in addition two side relative with this two side respectively forms corresponding six location holes 11, and the location hole 11 of every sidewall is suitable with the positioning convex point of opposing sidewalls 6 sizes.When two battery cases 1 were assembled mutually, the sidewall positioning convex point by first battery case embedded the location hole of the second battery case respective side walls and finishes.
