Detailed description of the invention
Below by specific embodiment and in conjunction with accompanying drawing, the application is described in further detail."front", "rear" in literary composition, "left", "right", " on ", D score is all with the laying state of the battery case in accompanying drawing for reference.
As shown in Figure 1-2, the embodiment of the present application provides a kind of battery case, including top cover 1, lower box 2, seal structure 3 and shackle member 5, lower box 2 surrounds and forms a cavity 4 holding battery modules, seal structure 3 and include sealing ring 31, accent around cavity 4, sealing ring 31 is arranged between lower box 2 and top cover 1, lower box 2 is connected by shackle member 5 engaging with top cover 1, and crush seal circle 31 realizes the sealing of battery case, the vertical section of sealing ring 31 is polygon, circular, semicircle or oval, process difform sealing ring 31 according to actual needs, while guaranteeing sealing, the multiple choices of the structure of sealing ring 31 also allow for the application of battery case.
Mostly existing battery case is to be bolted connection top cover 1 and lower box 2, then battery case is packaged by fitted seal bar again, but encapsulation needs more bolt, in assembling process, it is poor that the more difficult control of tightness of bolt in turn results in multiple bolt tightness concordance, have impact on the packaging effect of battery case, add the failure risk of battery.The application adopts that shackle member 5 is fixing connects top cover 1 and lower box 2, it is to avoid bolt connects the problem that the tightness degree existed is inconsistent, further improves the packaging effect of battery.
In embodiments herein, shackle member 5 includes buckle 51 and hole clipping 52, and buckle 51 is arranged on lower box 2 around cavity 4, and hole clipping 52 is arranged on top cover 1, and with buckle 51 one_to_one corresponding, lower box 2 and top cover 1 are engaged with hole clipping 52 by buckle 51 and connect.The mode that the application engages with hole clipping 52 by adopting buckle 51 is fixing is connected lower box 2 and top cover 1, it is ensured that the tightness degree that lower box 2 engages with top cover 1, will not increase battery failure risk because of the right inconsistent packaging effect affecting battery case of card.
In order to better realize sealing, the sealing structure 3 of the application also includes seal groove 32, seal groove 32 is arranged on lower box 2 or top cover 1, embodiments herein is provided with seal groove 32 on lower box 2, seal groove 32 is to arrange around the accent of cavity 4, and match with sealing ring 31, during assembling, sealing ring 31 is placed in seal groove 32, sealing ring 31 and seal groove 32 fit tightly, thus ensureing the compactness of cell package, owing to seal groove 32 and sealing ring 31 match, the vertical section of seal groove 32 can also be polygon, circular, semicircle or oval.
As shown in Figure 3, the buckle 51 of the application includes clamping joint 511 and card extension bar 512, clamping joint 511 is arranged on card extension bar 512, and it is extended to the side of card extension bar 512 along the radial direction of card extension bar 512, card extension bar 512 is through hole clipping 52, and the bottom surface 513 of clamping joint 511 contacts with the end face of top cover 1 and by top cover 1 clamping.Clamping joint 511 extends to the side of card extension bar 512 and is not only easy to clamping joint 511 traverse hole clipping 52 but also can ensure that the tightness degree that buckle 51 engages with hole clipping 52.The vertical section of clamping joint 511 is polygon, semicircle or half elliptic, can process difform clamping joint 511 according to the actual requirements, widen the range of application of clamping joint 511.
In order to hold battery more easily, lower box 2 in embodiments herein is the body structure of rectangle, and in order to process and easy to assembly, embodiments herein make to be positioned at lower box 2 same on the clamping joint 511 of buckle 51 extend to the same direction of card extension bar 512 each along the radial direction of card extension bar 512.And make clamping joint 511 extend away from the direction of cavity 4 along the radial direction of card extension bar 512 to card extension bar 512, if the clamping joint 511 of the buckle 51 that will be located on the one of lower box 2 group opposite side is oppositely arranged, when specifically assembling, sealing ring 31 is easily blocked by clamping joint 511 and is not easy to be assembled in seal groove 32.Therefore, embodiments herein will be located in the clamping joint 511 of the buckle 51 on one group of opposite side of lower box 2 and deviates from mutually and arrange each other, additionally by the multiple buckles 51 on lower box 2 being set to the equal tightness degree strengthening cell package further of spacing, accordingly, the spacing of multiple hole clippings 52 being distributed on top cover 1 is also equal.
nullThe bottom surface 513 of clamping joint 511 is also designed to by the side away from card extension bar 512 extremely near a structure being sloped downwardly of card extension bar 512 by embodiments herein,When specifically assembling,Namely the bottom surface 513 of clamping joint 511 props up top cover 1 can realize the engaging to lower box 2 and top cover 1,And if the bottom surface 513 of clamping joint 511 is a plane paralleled with the end face of top cover 1,When being subject to top cover 1 active force from bottom to up,Clamping joint 511 needs the effect of complete holding capacity,And power is focused on the junction of clamping joint 511 and card extension bar 512,Clamping joint 511 sensitive for damages,Therefore,The clamping joint 511 adopting this structure needs higher intensity,And if the bottom surface 513 of clamping joint 511 is an inclined-plane,When being subject to top cover 1 active force from bottom to up,Bottom surface 513 is the intensity that the clamping joint 511 of ramp structure reduces active force,Make the overall stress of buckle 51,Reduce the difficulty of processing also reducing clamping joint 511 while clamping joint 511 requirement of strength.
Top cover 1 and lower box 2 are connected together by the battery case that the present embodiment provides by shackle member 5, between top cover 1 and lower box 2, it is provided with sealing ring 31 simultaneously, crush seal circle 31 when top cover 1 connects with lower box 2 engaging, improves the packaging effect of battery case, reduces the failure risk of battery.
These are only the preferred embodiment of the application, be not limited to the application, for a person skilled in the art, the application can have various modifications and variations.All within spirit herein and principle, any amendment of making, equivalent replacement, improvement etc., should be included within the protection domain of the application.
