Embodiment
Below in conjunction with specific embodiments and the drawings, further illustrate the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.
As shown in Figure 1, a kind of battery case 1, described shell 1 comprises housing 2 and loam cake 3.Housing 2 is the container-like material that is formed by the injection molding machine injection moulding.Loam cake 3 is provided with positive terminal 5 and negative terminal 6, be provided with closing line 4 between described housing 2 and the described loam cake 3, described closing line 4 connects housing 2 and forms closure shell with described loam cake 3, described loam cake 3 is connected the upper surface that also closely is inlaid into described housing 2 with described housing 2 with ultrasonic welding structure, forms one and can hold the closed structure that battery is arranged.Owing to adopted ultrasonic welding structure, the profile of battery is compact more to be simplified, and the battery seal operation is convenient, and the operating efficiency in workshop improves.
During production, the sheathing material of described battery can be a plastic casing, for example the ABS engineering plastics.Adopt plastic casing can alleviate the weight of battery greatly, be easy to carry.
The housing of plastic material is by the injection molding machine injection mo(u)lding, and transition arc R3.5mm is adopted in the housing side, lowers the injection mo(u)lding difficulty, and makes housing more attractive in appearance.Case top lid 3 closely is inlaid into the upper surface of described housing 2, and forms closed structure with ultrasonic wave and the welding of described housing.(seeing following Fig. 3 and Fig. 4)
