M355464 [Embodiment] The above is an overview of the present invention, and in order to achieve a better understanding and recognition of the features, functions and objects of the present invention, several preferred embodiments are described in conjunction with the drawings. Explain later. - Figure 2 is an axial cross-sectional view of a preferred embodiment of the present invention. Figure 3A is a partial enlarged view of Figure 3. Figure 3B is a partial enlarged view of Figure 3. Figure 4 is a bottom plan view of the security sheet of the preferred embodiment of the present invention. Figure 5 is a bottom plan view of the positioning member of the preferred embodiment of the present invention. Figure 6 is a plan view of a cap of a preferred embodiment of the present invention. Figure 7 is a cross-sectional view showing a state in which the charging is interrupted in the preferred embodiment of the present invention. Figure 8 is a schematic view of the internal pressure state of the battery in accordance with a preferred embodiment of the present invention. As shown in FIG. 3, the present invention is a battery-to-safety-good embodiment, which mainly includes a base (10), a safety piece (10), a granular piece (10), and a cap (fine), wherein the base is composed of (10) The outer ring is composed of a riser (10), and the safety piece (10) is a piece of safety piece (10) which is disposed on the inner edge of the ring piece (10) and is connected to the base ((8), the positioning piece (10) and the cap (10) axis jump (10) rod The positioning member (the paste edge and the ring piece=) is adjacent to each other, and the annular insulating sheet (10) is interposed between the positioning member (10) and the ring piece (10), and the clamping member (10) has a similarity to the shape of the _ shape. The outer circumference is bent inward to form an annular buckle piece (10), and the periphery of the cap (10) extends between the buckle pieces (10): following (10) the touch of the right set - the lion_qing, the inner edge of the inner edge of the city - the mechanical flange ((6) and the buckle (10) Neighbor, according to the axial direction limit positioning member M355464 (10), 俾录峨尔; please refer to, fix the um (_ heart injury axially protrudes a shaft joint (36), the shaft joint (10) shaft wears the safety piece The inner edge of the ring of (20) is formed radially at the end (10), and the sealing piece (10) and the body (10) are opposite to the part of the security piece (10) adjacent to the thin edge, and the security piece is closely riveted with the plum (10). _3 4 and map As shown, safety) runs through a number of _ • (10) Guangpeng Quanqing fine shot ♦, good to the bottom edge # between the phase (four) shell hole (22) to form a groove (10), the radial section of the groove (10) Cheng Qing's groove (10)_ minute extension is connected with the adjacent through hole (10). According to this, when the pressure is from the pressure of the Tiberium, and the pressure value reaches the value of the Huan, the safety piece (2〇) is produced, and the groove is produced. (24)_ 'Separate the central part of the safety piece (10) to be separated; as shown in Figure 2B and Figure 5, the 4 piece (10) is on the bottom edge surface of the adjacent safety piece (10), around the axis of the positioning member (10) An annular notch (39) is formed, and the radial section of the notch (10) is π-shaped, and the notch (10) is adjacent to the inner edge of the ring of the insulating sheet (52), so that the positioning member (10) can be broken according to the lack of fineness. The central part of the piece (10) is separated from the peripheral part, and the internal pressure of the battery is provided. Referring to Figures 3 and 6, the cap (10) runs through a plurality of venting holes (4) to vent the internal pressure of the battery. β, please refer to the third and figure seven, when the lithium f pool is different, the internal gas of the battery [over the pre- < value '* full piece (10)) and the positioning piece (10)) (10) To the constant pushing force from the inside of the battery, since the groove (10) of the safety piece (10) is extremely deep, the thickness of the groove (24) itself is not large, so when the pressure is greater than the groove (10) M355464 The bearer first breaks the safety (10) along the groove (10) to separate the central portion of the safety piece (10) from the peripheral portion, and the central portion of the safety piece (10) after breaking and the positioning member (30) are topped. Turning in the direction of the towel cover (10), according to the forced cap charging, to avoid the excessive charge caused by the battery or fire, and because the woven (10) is formed with the venting hole (42), so that the stomach cover (10) and the positioning member (10) The air_force, the magnetic pair positioning member (30) is displaced toward the cap (10) to form a resistance block; please refer to Figure 7 and Figure 8 if the battery charging cap is still activated due to the continuous activation of the battery, the internal pressure of the battery Continue to increase 'The pressure is formed on the positioning piece (10) after the safety piece (10) breaks) The pushing action 'causes the positioning member (30) to break along the annular notch (10), so that the pressure inside the battery can be released externally through the vent hole (10) of the cap (10), thereby improving battery safety. By. Since the safety piece (20) is under pressure, the safety piece (10) is separated from the healthy peripheral portion of the central portion of the towel by the breakage of the groove (10) and the through hole (22), thereby achieving the effect of interrupting the charging, thereby promoting The critical pressure value at which the safety piece (2〇) breaks at the groove (24) can be determined by the thickness of the safety piece (20) at the groove (24) and the strength of the material selected for the safety sheet (2〇). For the Jia and s, it is easy to accurately control the critical Lili value that the safety piece (2〇) can withstand, avoiding the problem of premature or late interruption of charging, and improving the reliability of interrupting charging. Furthermore, the critical pressure value at which the positioning member (30) is broken at the notch (39) is also obtained by the thickness of the positioning member (30) at the notch (39) and the strength of the material selected for the positioning member (30). The decision 'samely, the manufacturer can easily and accurately control the critical pressure value that the positioning member (3〇) can withstand' avoids the problem of premature or too late fracture of the positioning member (30) at the notch (39). In summary, the technology of this case is compared with the prior art. In this case, the battery safety device/〇M355464 is designed as two protection mechanisms, and the conductive structure of the battery is separated from the safety financial plan to solve the poor structure of the known technical towel. The problem of rate, to achieve more progressive effects.
