Description

[Detailed description of the invention] [Industrial application field] This invention relates to a rechargeable lighting lamp, and more specifically, it has a built-in rechargeable battery that is powered by a car battery via a cigarette lighter socket. This invention relates to a rechargeable lighting lamp that can be taken out of a lighter socket and carried around for lighting.

[Prior Art] This type of vehicle interior light is conventionally described in, for example, Japanese Utility Model Application No. 59-117551.

This conventional technology is an interior light for a vehicle, which is characterized by having a built-in rechargeable battery that is charged by a power source, a handy lamp bulb that is lit by the rechargeable battery, and being detachably attached to the ceiling surface.

[Problem to be solved by the invention] The above-mentioned conventional technology is a removable ceiling light that is installed on the ceiling of a car interior, and the power receiving plug at the base of the light is inserted into a cigarette lighter socket to charge the lamp. It is very impossible to directly illuminate a map etc. at hand by operating a switch while the battery is in a charged state.

In addition, the above-mentioned conventional technology requires installing a detachable part for a handy lamp with a special contact piece on the vehicle ceiling, making the structure more complicated and costly compared to the invention of the present invention which uses a cigarette lighter socket. There is a problem.

Furthermore, the part indicated by reference numeral 15 in this conventional example is probably a charging circuit, but the circuit diagram in Figure 7 of the above publication does not have a lamp or light emitting diode to indicate charging, so it is difficult to tell whether charging is in progress or not. Moreover, when the handy lamp is turned off, it is difficult to know where the handy lamp is in the car at night, making it very inconvenient to use.

Moreover, if the contact parts are mistakenly brought into contact with each other with metal or the like, the battery itself will be shot through the resistor R and the circuit 15, creating a serious problem.

In order to eliminate each of the above-mentioned problems, this invention allows charging of rechargeable batteries by inserting the power receiving plug into the existing cigarette lighter socket on the car's dashboard, etc., and also makes it possible to light up the lamp while charging. The purpose is to make it possible to carry and use the light by removing it from the socket.

[Means for Solving the Problems] The purpose of the above-mentioned invention is to create insulating hollow cases 1, 1 which are molded into two approximately square-shaped plastic parts, and each hollow case 1, 1 to form a cylindrical shape. A cigarette lighter socket contact 21 is housed in the contact accommodating portions 12b, 12b together with a spring 22 through semicircular notches 16a, 16b formed at one end, and is disposed so as to be protruded by the spring 22, and both hollow cases 1 , 1 of the other hollow case 1 so that a portion thereof protrudes from the through holes 14a, 14a formed in the side surfaces of the other hollow case 1.
A contact plate 24 for a cigarette lighter socket made of a conductive spring material disposed on one end side of the cigarette lighter socket 2a.
and the battery accommodating portion 12a of the one hollow case 1.
a terminal plate 3 disposed on the other end side so as to face the base of the contact plate 24;
4, and the battery accommodating portion 1 between these plates 24, 24 by contacting the base of the contact plate 24 and the terminal plate 34, respectively.
2a and the battery housing section 1 of the other hollow case case 1
The rechargeable batteries 6, 6 housed in 2a, the terminal plate 37 which is integral with the terminal plate 34, and the other end of the trapezoidal shape of the hollow cases 1, 1 are fitted so that one pole is connected to the terminal plate 37. With the movement of the light bulb 32 held between the reflector portion 41 of the cap 4 and the switch bullet 31 whose one end is in contact with the other pole of the light bulb 32, the other end of the bullet 31 is moved. a terminal 33 disposed at a position where the terminals 33 and 24 come into contact with each other; the contact plate 24 connected to the terminal 33; and the spring 22.
A charging protection element 5 connected between a conductive piece 23 connected to a cigarette lighter contact 21 via
and is connected between the output side of this element and the terminal plate 34, and is exposed through a through hole 14b provided in the upper inclined part of the above-mentioned F-shaped hollow case 1, 1 on the side where the lamp bulb 32 is attached. This is achieved by providing a lighting diode 36 for both charging and backflow prevention, which is arranged at the same time, and a stand S that can be raised and lowered, with both ends inserted into the lower sloped part of the lamp bulb 32 mounting end of the cases 1, 1. can.

[Function] By inserting the base of the hollow case into the cigarette lighter socket, the contacts and contact plate arranged at this base can be connected to the vehicle battery through the cigarette lighter socket, and the rechargeable battery inside the hollow case can be connected to the contacts and the contact plate. It can be charged by sequentially passing through the spring, conductive piece, charging protection element, lead wire, charging and backflow prevention light emitting diode, and contact plate.

The battery can be recharged by pressing the switch bullet and bringing it into contact with the terminal.The battery can be recharged by passing through the positive terminal of the battery, the terminal plate, the light bulb, the switch bullet, the terminal, the charging protection element, and the contact plate in sequence. Current flows through the negative terminal of the lamp, which can light up the lamp bulb.

Note that the above lighting is lit while the rechargeable battery is generating an electromotive force, regardless of whether it is being charged or not.
