SOLUTION: The main body is provided with a light section, a secondary battery, an electric control section and a solar cell panel, and the secondary battery can be charged with electric energy generated by the solar cell panel via the electric control section or A solar cell type flashlight in which the secondary battery can be charged from a vehicle power source via an electric control unit and the electric light unit can be turned on by the secondary battery via the electric control unit.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is a solar-powered flashlight, which is used in remote areas and in emergency situations.

[0002]

[Prior art]

 Conventional flashlights include a dry battery type and a commercial power source rechargeable type. In the dry battery type flashlight, the lighting part is turned on by the primary battery, and in the rechargeable flashlight, the secondary battery is charged by the commercial power source of 100, and the secondary battery is charged by the secondary battery. The lighting fixture is lit.

[0003]

[Problems to be solved by the device]

 However, since the dry battery type flashlight uses the primary battery, it cannot be used when the battery is exhausted and the dry battery must be replaced when it is used. There was a case that it was not very convenient to use. On the other hand, a commercial power rechargeable flashlight can be recharged at any place because it requires recharging from a 100V power source, though it does not require battery replacement. Since it is necessary to recharge the battery, it is easy to forget to charge it, which is not convenient for use.

An object of this invention is to eliminate such inconvenience.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in a solar cell-type flashlight according to the present invention, a main body is provided with a light section, a secondary battery, an electric control section, and a solar cell panel, and the above-mentioned electric control section is used. The secondary battery can be charged with the electric energy generated by the solar cell panel, or the secondary battery can be charged from the vehicle power source through the electric control unit, and the secondary battery can be charged through the electric control unit. Since the electric light unit can be turned on, the rechargeable battery can be charged and the lighting unit can be turned on by the rechargeable battery if there is sunlight or an automobile power source.

Further, the main body is composed of a synthetic resin lighting part and a synthetic resin body part, and a fitting insertion hole is formed on a front surface of the body part and a protrusion is formed on a rear surface of the lighting part. If the protrusion is inserted into the insertion hole of the body with almost no gap and a stopper is formed at the tip of the protrusion, the body and the lighting fixture can be swung slightly. Therefore, as a result of being able to absorb the shock received by these parts, it is possible to prevent damage when the flashlight is dropped or hit somewhere.

Embodiments

 1 to 3, 10 is a solar cell type flashlight, and 1 is its main body. The main body 1 is composed of a lighting portion 11 made of synthetic resin and a body portion 12 made of synthetic resin. The body 12 has a fitting hole 121 on the front surface. The lighting unit 11 has a protrusion 111 on the rear surface. The lighting portion 11 is connected to the body portion 12 by inserting the protruding portion 111 into the fitting insertion hole 121 of the body portion 12 with substantially no gap. Incidentally, 112 is a retaining member and is integrally formed at the tip of the projecting portion 111.

Reference numeral S denotes a solar cell panel, which is fitted into the side surface opening 1 c of the main body 1 and fitted into the step portions 1 d and 1 d. The solar cell panel S converts sunlight into electric energy.

A secondary battery B is housed inside the body 12. The secondary battery B is positioned by the locking holders F1 and F2. The secondary battery B is for charging the electric energy generated by the solar cell panel S. Incidentally, F is a hook for supporting the secondary battery.

Reference numeral J denotes a fitting receiver, which is installed on the back surface of the body 12. The fitting receiver J is electrically connected to an electric control unit C described later. 5 is a cigar tyler fitting, which is connected to a jack 52 via a cord 51. The cigar tyler fitting can be detachably connected to the fitting receiving device J through the jack 52. The cigar tyler fitting 5 is detachably fitted to a cigar lighter (not shown) of an automobile to use the power of the cigar lighter. The power source of this cigarette lighter corresponds to the automobile power source D of the present invention.

Next, C is an electric control unit, which is installed inside the lighting unit 11. The electric control unit C charges the secondary battery B with the electric energy generated by the solar cell panel S, charges the secondary battery B from the power source of the cigarette lighter, or charges the secondary battery B. The battery B is used to light the electric light section L described later. Furthermore, the electric control unit C allows the flow of current from the power source of the solar cell panel S and the cigarette lighter to the secondary battery B and the light bulb L, but from the load side to the power source of the solar cell panel S and the cigarette lighter. It has a backflow prevention function to prevent backflow of electricity, a function to prevent overcharge from the solar cell panel S and cigarette lighter power source to the secondary battery B, and a function to prevent overdischarge from the secondary battery B to the load L. .

Reference numeral L denotes an electric light unit, which is installed on the front surface of the lighting unit 11. The electric lamp unit L is turned on by discharging the secondary battery B. In addition, H is a handle, 1a and 1b are leg sides, both are installed on the body 12, and the lighting switch SW is installed on the lighting unit 11.

In the solar cell type flashlight, when it is not used during the daytime or when it is not used, the solar cell panel S can be directly irradiated with the sunlight by leaning it against the stand G as shown in FIG. 2 to charge the secondary battery B. Is done effectively enough.

The present invention is not limited to the above embodiment, and design changes can be made within the scope of the invention. For example, the arrangement position and design of the solar cell S can be changed appropriately.
