Abstract

The utility model discloses a chargeable torch which can charge the batteries by itself. The problem in which the charging of the ordinary batteries is inconvenient is solved. The inner of a tailstock of the chargeable torch is provided with a copper reed 1, a copper sheet 2, etc., which forms a linked switch. A rectifying element is welded to the copper reed 1, the copper sheet 2, an inserting pillar 3 and an inserting pillar 4 respectively. A spring 9 and the copper sheet 2 are welded. A spring seat 8 and a socket board 6 are fixed to the inner of the tailstock 5 by two screws.

Description

Chargeable torch

The utility model is the chargeable flashlight of a kind of energy self charging, relates to daily necessities.

Existing common flashlight can not self be charged, and charges the battery and use stabilized voltage power supply, also need join and buy battery case, and all battery must be got at every turn and keep forging ahead out, quite inconvenience.

The purpose of this utility model just is to provide a kind of chargeable flashlight that can directly charge the battery.

The utility model achieves the goal by following technology: cashing has the torch tailstock for the charging tailstock, promptly increases rectification circuit, linked switch and charging socket in tailstock.After charging plug inserted socket, by linked switch, torch transferred charged state to automatically by illumination condition, and power supply from the positive pole battery of flowing through, thereby charges the battery behind over commutation.

Feature of the present utility model will be illustrated more clearly in from the accompanying drawing of following enforcement.

Fig. 1. the structure chart of charging tailstock.

Fig. 2. the fundamental diagram of charging tailstock.

Fig. 3. charging principle figure.

The structure of charging tailstock as shown in Figure 1, tailstock body 5, socket 6, spring base 8 are made by insulating material.The interface of tailstock body 5 is threaded, and is connected with the flashlight housing.After the connection, the negative pole and torch (metal) housing of battery are connected into path by spring 9, copper sheet 2, copper reed 1.

The copper reed 1 of tailstock, copper sheet 2 etc. constitute linked switch.After charging plug inserts socket aperture, copper reed 1 will separate automatically with the contact of copper sheet 2; After charging plug is extracted, its contact will be connected again automatically.

Have boss 7 on the spring base 8, in order to determine the distance on spring base and 6 liang of planes of socket, so that the space mounting rectifier cell to be provided.Rectifier cell is connected respectively with copper reed 1, copper sheet 2, inserting column 3,4 by welding.Spring 9 welds mutually with copper sheet 2.Spring base 8 and socket 6 together are fixed in the inside of tailstock body 5 by two screws.

Fig. 2. be the circuit diagram of chargeable flashlight.K is a torch switch, and ZD is a small electric bulb, and E is battery (group), and D1～D4 constitutes rectification circuit.

Fig. 3. be charging principle figure.Charge power supply is provided by miniature transformer, promptly by transformer B output low-tension supply, after D1～D4 rectification, the negative pole of power cathode and battery (group) joins, when positive source charges through torch switch K(, K is in closure state), the positive pole of small electric bulb ZD and battery (group) joins, add the forward voltage slightly higher for battery (group), thereby charge for battery (group) than its rated voltage.

When using chargeable flashlight, should correctly connect the power line of charging plug.During charging, torch switch is placed the illumination position, plug charging plug and just can charge automatically, charging is pulled out plug after finishing, and torch recovers illumination condition immediately.

Compare with prior art, the utlity model has following advantage:

1. charger and torch are combined as a whole, dual-use material, easy to use.

2. flashlight is made charger, can be radio, the charging of radio cassette player battery.

3. simple in structure, easy to manufacture, cost is low.

Claims

1, a kind of chargeable flashlight that can directly charge the battery is characterized in that being equipped with in the tailstock rectifier cell, linked switch and charging socket.The copper reed 1 of tailstock, copper sheet 2 etc. constitute linked switch, have boss 7 on the spring base 8, rectifier cell links to each other respectively with copper reed 1, copper sheet 2 and inserting column 3,4 by welding, and spring 9 welds mutually with copper sheet 2, and spring base 8 and socket 6 together are fixed in the inside of tailstock body 5 by two screws.

2, chargeable flashlight as claimed in claim 1 is characterized in that tailstock body 5, spring base 8, socket 6 usefulness insulating material make.

3, chargeable flashlight as claimed in claim 1, after it is characterized in that tailstock and the torch housing being connected, copper reed 1 contacts well with (metal) housing.

4, chargeable flashlight as claimed in claim 1 is characterized in that the contact of copper reed 1 and copper sheet 2 separates automatically after charging plug inserts the tailstock hole; After charging plug was extracted, its contact was connected again automatically.
