Embodiment
Further specify the technical solution of the utility model below in conjunction with Figure of description and specific embodiment.
As shown in Figure 1, a kind of power brick that is used for electric powered motor of the present utility model, it is made up of inlet pipe connection 1, upper shell, battery frame 5 and lower house 7, upper shell forms integrative-structure by protecting cover 2, exhaust connection 3 and manifold 4, protecting cover 2 is provided with one group of non-grade of diameter and arranges uneven manifold 4, described manifold tubing string and exhaust main connect as one, the protecting cover of the upper shell of described power brick and the angle between the horizontal plane are the 3-8 degree, and the lower house of described power brick and the angle between the horizontal plane are the 3-8 degree.
As shown in Figure 2, at upper shell 5 manifold structures of one group of diameter arrangement of gradients are arranged, thickness of pipe wall is 0.8-2mm.The manifold diameter is descending to be respectively: the first manifold outer diameter D 1 is (2/3-8/11) L doubly, and the second and the 4th manifold outer diameter D 2 is (3/4-5/6) L doubly, and the 3rd and the 5th manifold outer diameter D 3 is (1/9-1/7) L doubly.Distance is as follows between the manifold tubing string: the distance L 5=(1-1.5) at the distance L 2=the 4th at the second and the 3rd manifold center and the 5th manifold center D1 doubly, the distance L 4=(1.2-1.6) at the distance L 3=the 4th at the second and first manifold center and first manifold center D1 doubly, the distance L 1=(0.3-0.8) of the 3rd and the 5th manifold center and power brick sidewall D1 doubly, L is a power brick contour dimension.Utilize in the automobile above tubing string or side space under the automotive floor panel, it is that 3-8 ° exhaust connection is connected wall thickness 0.5-2mm with manifold that an inclination angle is arranged.Battery cell adopts frame-type to install, and battery frame is provided with evenly distributed aperture, and diameter is 5-10mm.
