Description

Plastic fiber direct charging battery

The present invention relates to a battery, and more particularly, to a rechargeable battery.

The secondary power sources in electronic industry and civil use are mostly direct current zinc-manganese batteries, lead-acid batteries and cadmium-nickel batteries, the zinc-manganese batteries become wastes after being used once, and although the lead-acid batteries and the cadmium-nickel batteries can be repeatedly charged and used, a charger is required to be additionally arranged and is charged in the charger, so that the batteries are not direct charging batteries which can be directly charged in general.

Chinese patent 92229311.2 "plastic fiber high-energy rechargeable battery" discloses a rechargeable battery using plastic as the outer shell and chemical fiber and chemical mixture as the filler, which has the advantages of large capacity, no corrosion, moisture resistance and impact resistance.

The utility model aims at making the charger and moulding fine high energy chargeable cell and mould fine direct rechargeable battery together, can needn't establish in addition the charger can charge to the battery, both saved the material, the cost is reduced has made things convenient for the user to widen the usage of direct rechargeable battery again.

The utility model discloses a mould fine direct rechargeable battery, including moulding fine high energy rechargeable battery and charger, the charger comprises power plug and step-down rectifier circuit, its characterized in that:

1) The plastic fiber high-energy rechargeable battery and the charger are arranged in the same plastic shell, an insulating plate is arranged in the middle of the plastic shell, one end of the shell is a battery anode, and the other end of the shell is a battery cathode;

2) A groove body which is integrally formed with the shell is arranged on the side wall of one end of the plastic shell;

3) The power plug is a telescopic movable plug arranged in a groove body of the side wall of the shell.

The positive and negative electrodes of the plastic fiber high-energy rechargeable battery are electrically connected with the charger through the insulating partition plate, and the negative electrode of the battery is connected to the negative plate of the direct rechargeable battery. When the direct charging battery is charged, the movable plug is pushed out of the groove body on the side wall of the shell, positioned and inserted into a 220V power socket, and when the battery is used, the movable plug is only required to be pushed back into the groove body on the side wall of the shell of the battery of the direct charging device.

The technology of the present invention will be described in detail with reference to the accompanying drawings of the embodiments

FIG. 1 is a schematic structural diagram of a plastic fiber direct-charging battery

FIG. 2 is a schematic diagram of a charger circuit

FIG. 3 is a schematic view showing the structure of a case of a direct-current rechargeable battery

FIG. 4 is a schematic structural view of a retractable movable plug

FIG. 5 is a schematic view of the negative plate of FIG. 1

FIG. 6 is a schematic view of the plastic insulating sheet shown in FIG. 1

Referring to the attached drawings, 1 is a direct-charging battery anode, 2 is a battery cover, 3 is an upper separator for sealing, a gap is left between the upper separator 3 and the

battery cover

2, 4 is a filled chemical fiber and chemical reaction mixture, 5 is a plastic shell of the direct-charging battery, 6 is a circular tube-shaped direct-charging battery cathode, 7 is a circular tube-shaped direct-charging battery anode, 8 is an anode nail fixed on a lower separator 10 and electrically connected with the

anode

7, 9 is a cathode nail fixed on the lower separator 10 and electrically connected with the cathode 6 and a battery cathode 12, 11 is a charger, 13 is a movable power plug, and 14 is a plastic insulating sheet fixed on the inner side of the battery cathode 12.

The plastic fiber high-energy rechargeable battery in the structure occupies about 2/3 of the volume of the whole direct rechargeable battery and is positioned at the upper part of the direct rechargeable battery, and the charger and the movable plug occupy 1/3 of the volume and are positioned at the lower part of the direct rechargeable battery.

The specification of the direct charging battery is the same as that of a first battery sold in the market.

Referring to fig. 2, the 220V commercial power is converted into direct current through resistance R1, electric capacity C1 step-down and diode bridge rectifier circuit, and R2 is current-limiting resistance, and D is emitting diode for instruct the charged state, and E is the utility model discloses a mould fine high energy rechargeable battery.

The embodiment direct charging battery changes 220V commercial power into electric power of 7V-12V and 50-100mA to directly charge the battery.

Referring to fig. 3, the housing 5 of the direct charging battery is formed by upper and lower two housing sleeves, the side wall of the lower housing has an arc groove 51 integrally formed with the housing, the two side walls in the groove have convex ribs 52 and 53, the ribs end at a certain height from the bottom end of the battery, and two elastic metal sheets 54 and 55 arranged on the insulating partition plate 10 of the direct charging battery extend into the groove and are electrically connected with the sliding sheet of the movable plug.

Referring to fig. 4, the movable plug 13 includes an arc push rod 131, a protruding push plate 132 is provided on the top of the push rod for applying a pushing force, the edge of the push plate 132 is flush with the notch of the slot 51 in fig. 3, and the thickness of the push plate 132 is exactly equal to the distance between the ends of the ribs 52 and 53 and the bottom of the battery in fig. 3. The bottom of the push rod 131 is provided with metal plugs 133, 134 which are injection molded with the push rod at one time and extend to form plug sliding blades on the back plane of the push rod.

The push rod 134 is arranged in the groove body 51 shown in fig. 3 to form a telescopic movable plug, the push rod 131 is kept in the groove body 51 due to the action of the elastic metal sheets 54 and 55 in the groove body 51, when the battery needs to be charged, the push rod 131 is pushed downwards until the top end surface of the push rod crosses the tail ends of the two side ribs 52 and 53 in the groove body, and the tail end surfaces of the two side ribs press the top end surface of the push rod 131 to position the plug. After charging, the push plate is pushed inwards to separate the top end face of the push rod from the restriction effect of the end faces of the two ribs, and then the push plate is pushed upwards along the groove body 51 until the plug 13 completely enters the groove body 51. The push rod 131 is held in the groove body 51 without falling due to the tension of the metal elastic sheets 54 and 55.

Referring to fig. 5, the negative electrode plate 12 has two rectangular grooves 121 and 122 through which the plugs 133 and 134 are inserted and withdrawn.
