As shown in the figure, a conventional secondary battery pack structure 9 includes a lower casing 9 〇, _ 10 upper casing 92 And the secondary battery core 91. The lower casing 90 houses a plurality of two-human battery cells 91 and their electrode sheets 912, 913 in the inner chamber 901, and the plurality of secondary battery cells 91 are bonded to each other by the adhesive 911. Or, after being tightened by a strap (not shown), it is accommodated in the chamber 901 of the lower casing 90, and then the upper casing 92 is closed. Further, a lithium battery is used as the secondary battery core 91, which has characteristics of large current and high power, and its charging operation temperature is 〇45. C, the operating temperature of the discharge is -20~60. Between C. In general, during the charging and discharging process of the secondary battery cell 91, the battery core generates heat, which directly affects the efficiency. In the conventional secondary battery pack structure 9, since the secondary battery cells 91 are deep inside the sealed internal chamber 901 and are in contact with each other, the heat generated during charging and discharging cannot be effectively dissipated and mutual The influence, in particular, the upper and lower casings 92, 90 form a barrier for each of the secondary battery cells 91 to contact with the air to dissipate heat, so that heat is accumulated in the closed portion between the upper casing 92 and the lower casing 90, 5 M332265 = chamber 9G1 The heat dissipation cannot be performed outward, and if the upper limit of the operating temperature of the above charging and discharging is exceeded, the charging and discharging efficiency of the secondary battery core 91 is not satisfactory. Further, when the secondary battery cell 91 is aged, the improperly flowing liquid and the gas flowing therethrough may cause damage and adverse effects on the secondary battery core 91, which may cause safety concerns. The design method of the secondary battery pack structure 9 is used for the design method of the fixed capacity. If it is necessary to respond to different capacitances, it is necessary to separately design and manufacture the shell and upper casing under different molds. And its secondary 10 battery anger also needs to be re-assembled' thus increasing the overall cost and reducing market competitiveness. [New content] This creation is a secondary battery pack combination structure, which includes an upper frame, a lower frame, and A plurality of secondary battery cells. 15 months. ί2 ϊ 包括 包括 包括 包括 包括 ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί ί 15 15 15 a plurality of inner hollow sleeves, and a plurality of grooves are recessed on the upper plastic partition, each groove corresponding at least corresponding to the top end of the upper sleeve and at least partially penetrated by the town The upper plastic truss bracket is further convexly disposed at a spacing of the plurality of upper sleeves to and recessed with at least one upper positioning hole, and the plurality of upper electrode knives are correspondingly placed in the plurality of grooves.

Since each sleeve is separated by a fixed interval between each secondary electric 15 core due to the thickness of the sleeve itself, it is easy to evacuate the secondary battery core. There is a gap between them, and it is easier to generate convection of air to dissipate heat generated during charging and discharging. At the same time, the interval of fixing also makes the calorific density of the secondary battery 4 per unit volume low, so that heat is less likely to aggregate. In addition, if the secondary battery cell is faulty or aged, the liquid or gas flowing out of it can be separately isolated from the plastic barrel of the upper sleeve and the lower sleeve without flowing around each other, so it is safer than the conventional one. Because the upper and lower plastic brackets all adopt the same structure, it can be easily combined and modularized. Among them, the above plastic bracket refers to a PC plastic bracket, and the lower plastic bracket refers to another PC plastic bracket or ABS.

In the first embodiment, the upper plastic support 122 includes a side plate 121 and the lower plastic support 222 includes another side plate 221. The other side plates 221 are on the same side as the side plates ΐ2ι and are flush with each other, and the circuit board 6 is disposed on the side plate 丨 21 and the other side plate 221. Of course, the second embodiment also has the same structure as the first embodiment, so as to facilitate the modular combination. 20, the circuit board 6 includes a control circuit, or a protection circuit, such as a voltage regulator circuit, a current stabilizing circuit, or other preventive supersaturation circuit, and in an embodiment, the circuit board 6 - Fang Hui It is fixed on the upper electrode sheets 117, 118, and the other side of the circuit board 6 is soldered to the lower electrode sheets 217, 218 to form a fixed portion; or the double-sided adhesive is adhered to the side plate 121 and the side plate 219 to be 12 M332265. In the second embodiment, the circuit board 6 is soldered to the upper extension electrode tabs 119, 120, and the other electrode tab 6 is formed to be fixed. - The mouth is extended on the electrode sheet for the sake of example, and the present invention is not limited to the above description. The above embodiments are only for convenience of explanation. The scope of the claim is from the patent application. example.
