Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of support frame 1 that the utility model embodiment provides, comprise the first supporting bracket 11, second supporting bracket 12 and two side frame plates 13; First supporting bracket 11 and the second supporting bracket 12 side by side and interval arrange, two side frame plates 13 connect the two ends of the first supporting bracket 11 and the second supporting bracket 12 respectively, thus make the first supporting bracket 11, second supporting bracket 12 and two side frame plates 13 surround in frame-shaped chamber 10; When the battery core of lithium ion battery is arranged in support frame 1, support battery core by support frame 1, prevent battery core to be out of shape.The lower side of each side frame plate 13 is convexly equipped with rib 14, and rib 14 is arranged along the length direction of this side frame plate 13, and protrudes extension towards the direction of opposite side deckle board 13; When battery core is arranged in support frame 1, rib 14 can be used for being buckled in battery core.
By arranging rib 14 at the lower side of two side frame plates 13, the intensity of corresponding side frame plate 13 can be increased, be out of shape to prevent support frame 1, and what side frame plate 13 can be made is relatively thin, and then the volume of this support frame 1 middle frame-shaped chamber 10 part can be made relatively large, thus more volume, more jumbo battery core can be installed in support frame 1, increase capacity and the yields of the lithium ion battery made.Rib 14 is set in addition, when battery core is arranged in support frame 1, can be buckled in battery core by rib 14, prevents battery core from coming off from the downside of support frame 1, the installation of battery core can be facilitated to fix.
Further, the medial surface of each rib 14 is that arc transition is connected with corresponding side frame plate 13 medial surface.The intensity of rib 14 can be improved so further, and then improve the intensity of side frame plate 13, prevent side frame plate 13 deformation.
Further, the two ends of each rib 14 are fixedly linked with the first supporting bracket 11 and the second supporting bracket 12 respectively.The two ends of rib 14 are fixedly linked with the first supporting bracket 11 and the second supporting bracket 12 respectively, the bonding strength of two side frame plates 13 and the first supporting bracket 11 and the second supporting bracket 12 can be increased, and then improve the intensity of this support frame 1, better prevent support frame 1 to be out of shape.
Further, the first supporting bracket 11, second supporting bracket 12, two side frame plates 13 and corresponding rib 14 are one-body molded.Thus ensure the intensity of this support frame 1.In the present embodiment, the first supporting bracket 11, second supporting bracket 12, two side frame plates 13 and corresponding rib 14 injection moulding integrated molding.By injection mo(u)lding, easy to process, simple, cost is low, facilitates industrial a large amount of production.In other embodiments, can also be punch forming etc.
Further, the thickness of each side frame plate 13 is 0.6 ~ 1mm.The thickness of side frame plate 13 is set to 0.6 ~ 1.0mm, in guarantee side frame plate 13 intensity, when the distortion of this support frame 1 of situation about preventing, the volume in middle frame-shaped chamber 10 can be arranged comparatively large, thus the battery core of more volume and capacity is installed well.Preferably, the thickness of side frame plate 13 can for 0.6mm be to make when support frame 1 overall volume of formed objects, to make the volume in its middle frame-shaped chamber 10 maximum.
Further, the lower side of the first supporting bracket 11 is convexly equipped with rib 111, and rib 111 is convexly equipped with rib 111 by the lower side of this first supporting bracket 11 towards the direction of the second supporting bracket 12.Rib 111 is set in the first supporting bracket 11, the intensity of the first supporting bracket 11 can be increased, to arrange relatively little by the thickness of the first supporting bracket 11, and then increase the volume in middle frame-shaped chamber 10; The protective circuit plate of support cells can also be carried out by rib 111 simultaneously.
Further, the first supporting bracket 11 offers the through hole 112 for being electrically connected with the external world for battery core.First supporting bracket 11 arranges through hole 112, to expose the electrode slice on protective circuit plate, convenient.Certainly in other embodiments, also by sheet metal, the electrode on protective circuit plate can be drawn outside this support frame 1.
Refer to Fig. 4; the utility model embodiment also discloses a kind of lithium ion battery 100, comprises support frame 1 as above, battery core 2 and protective circuit plate 3, and battery core 2 is arranged in support frame 1; protective circuit plate 3 and battery core 2 are electrical connected, and protective circuit plate 3 is installed in support frame 1.See also Fig. 1, this lithium ion battery 100 employs above-mentioned support frame 1, the battery of same volume, because the volume in the frame-shaped chamber 10 of this support frame 1 is relatively large, thus more volume, more jumbo battery core 2 can be installed in support frame 1, increase the capacity of the lithium ion battery 100 made.In addition, the use due to rib 14 makes the intensity of side frame plate 13 larger, and the distortion preventing battery that can be good, improves the yields of the lithium ion battery 100 produced.
Further, the both sides that this lithium ion battery 100 also comprises the first fixed head 4, first fixed head 4 being placed on support frame 1 bottom side are connected with two ribs 14 respectively.The effect that first fixed head 4 can play protection battery core 2 is set; The intensity of lithium ion battery 100 can also be increased in addition, better prevent the distortion of support frame 1.Further, the first fixed head 4 can be steel plate or aluminium alloy plate etc., to dispel the heat to battery.The both end sides of the first fixed head 4 can also be fixedly linked with the first supporting bracket 11 and the second supporting bracket 12 respectively.
Further, the both sides that this lithium ion battery 100 also comprises the second fixed head 5, second fixed head 5 be placed on the upside of support frame 1 are connected with two side frame plates 13 respectively.The effect that first fixed head 4 can play protection battery core 2 is set; The intensity of lithium ion battery 100 can also be increased in addition, better prevent the distortion of support frame 1.Second fixed head 5 can be PVC board.The both end sides of the second fixed head 5 can also be fixedly linked with the first supporting bracket 11 and the second supporting bracket 12 respectively.
Further, this lithium ion battery 100 also comprises protection strip of paper used for sealing 6.Protection strip of paper used for sealing 6 is set; support frame 1, first fixed head 4 and the second fixed head 5 can be comprised by protection strip of paper used for sealing 6; not only can play the effect of protection; first fixed head 4 and the second fixed head 5 can also be pasted onto on protection strip of paper used for sealing 6, prevent the first fixed head 4 and the second fixed head 5 from coming off.In addition, decorative pattern etc. can also be set on the outer surface of protection strip of paper used for sealing 6, to facilitate difference and to install and use.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
