Description

[Detailed description of the device]

[0001]

[Industrial applications]

  This device is installed in a car and used as an emergency light or a portable light It is about charging lights that can be.

[0002]

[Prior art]

  All cars have an emergency light inside. Used in an emergency However, in reality, it is rarely used. For automobile The light mainly has a built-in dry battery.

[0003]   Also, insert the car plug into the cigarette lighter socket of the car before use. An automotive light has also been devised (Japanese Utility Model Publication No. 63-4001). This car The light for lighting has a car plug connected to the tip of the lead wire connected to the light bulb. It uses the battery of a moving vehicle as a power source.

[0004]

[Problems to be solved by the device]

  The dry battery type emergency light installed in a car is Often cannot be lit. It is very rarely used, so dry batteries The reason is that is self-discharging. Use the emergency light in an emergency And, it must be able to light up when necessary.

[0005]   If you put the rechargeable battery in the emergency light and charge the rechargeable battery every appropriate period, It can always be turned on in an emergency. However, rechargeable batteries self-discharge when the temperature rises. There are many characteristics. The interior of a car gets hot, so use it by self-discharge The period that can be done becomes short, and it is necessary to repeat charging frequently.

[0006]   On the other hand, a light used by inserting a car plug into the cigarette lighter socket. Can't carry around freely. It connects to the car socket with a lead wire. Because it will continue. Therefore, it cannot be used as an emergency light. For example, tread If the car seems to stop due to being turned off, get out of the car and signal with the emergency light However, it has an inconvenient drawback.

[0007]   This invention aims to solve the drawbacks of these conventional automotive lights. It was developed for the purpose, and the important purpose of this device is to worry about self-discharge of the rechargeable battery. No, there is to provide a charging light for automobiles that can be used with peace of mind at all times.

[0008]   Another object of this invention is to display the elapsed time of warm-up operation of the vehicle, An on-board charger that can be used as a car accessory that does not get bored during warm-up operation To provide electric lights.

[0009]

[Means for Solving the Problems]

  The vehicle-mounted charging light of the present invention supplies electric power to the light emitting unit and the light emitting unit. A light body including a battery for emitting light, and a cigarette lighter socket of a car And a car plug that can be connected to the It consists of a charging stand that charges the pond.

[0010]   In addition, the light body is supplied with power from the vehicle battery via the charging stand. When the power is turned on, an elapsed time display unit that displays the elapsed time from the time of power supply is provided.

[0011]

[Action]

  The car charging light of this invention connects the plug to the cigarette lighter socket Then, by placing the light body on the charging stand, you can charge the battery while driving the car. it can. Also, when using the light, by removing the light body from the charging stand, Can be freely carried and used.

[0012]   Furthermore, the light of this invention, when powered by the car battery, The elapsed time display section shows the time elapsed since the power was supplied. It is possible to know the elapsed time from the time when-is turned on. For this reason, It can be used as a cheap.

[0013]

【Example】

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0014]   This light is composed of a charging stand 1 and a light body 2 mounted on the charging stand 1. There is. The charging stand 1 has a car plug 3 connected to the ends of the lead wires. Car plug 3 Is shaped to connect to a cigarette lighter socket of an automobile. Car plastic The lead wire 4 connected to the plug 3 is connected to the connection terminal 5 protruding on the upper surface of the charging stand 1. Has been. The connection terminal 5 is fitted and connected to the light body 2 and is also installed on the light body 2. A charging current is supplied by electrically contacting a broken connection terminal (not shown).

[0015]   The light body 2 has a light emitting portion 7 having a light source 6 built in on the front surface and a switch 8 on the side surface. Have The light-emitting part 7 is connected so as to be tiltable, and when used, as shown in FIG. Raise as shown to use. The light emitting unit 7 adjusts the raising angle of the light source 6 and The light irradiation direction can be adjusted, and it can be folded thin so that it does not take up space when not in use. You can The switch 8 is connected between a Ni-Cd battery described later and the light source 6, and is turned on. In this state, the light source 6 is turned on.

[0016]   Further, the light body 2 has a built-in Ni-Cd battery 9 and an elapsed time display unit 10. It The elapsed time display unit 10 displays the five LEDs 11 and the number of lights of the five LEDs in order. A timer-delay unit 12 for increasing the number next time is provided. LED11 is It is installed on the main body so that it can be seen from outside.

[0017]   In the elapsed time display unit 10, as shown in the electric circuit diagram of FIG. 4, the light body 2 is a charging stand. 1 is connected so that it is powered from the car battery ing. Therefore, from the battery of the car through the car plug 3 and the charging stand 1, When power is supplied to the main unit, charging of the Ni-Cd battery 9 is started and the elapsed time The display unit 10 is energized and driven. That is, by turning on the ignition key Then, the elapsed time display unit 10 is automatically driven. Where the timer-delay The part 12 is provided with a time constant circuit consisting of a capacitor and a variable resistor, The number of the LEDs 11 to be turned on is increased by one each time the time passes (see FIG. 3). this At this time, the user can use it as a guide for warm-up operation by checking the lighting of the LED. can do. In addition, the cycle in which the number of the lit LEDs increases is It can be set freely by adjusting the variable resistance of the imager delay unit 12.

[0018]   Further, in FIG. 4, the diode 13 connected in series with the Ni-Cd battery 9 is A charging current is passed from the automobile socket toward the Ni-Cd battery 9, The battery 9 is connected in a direction in which it does not flow back to the battery of the automobile. Therefore automatic Even if the car battery voltage drops, the Ni-Cd battery will not be discharged. It

[0019]   As shown in FIG. 5, the vehicle-mounted charging light of this structure has the charging base 1 mounted on the vehicle. Attach it to the instrument panel or console of the car and attach the car plug 3 to the cigarette lighter Use it by plugging it into the tablet. Normally, the light body 2 is placed on the charging stand 1, Charging is always done while driving a car.

[0020]

[Effect of device]

  The car-mounted light of this invention is a cigarette lighter socket with a car plug. Insert and use. The car plug connected to the cigarette lighter socket is Charge the battery via the charging stand while the vehicle is running. Therefore, it is not suitable for high temperature external environment. And rechargeable batteries, such as Ni-Cd batteries, which have large self-discharge, do not worry about self-discharge. It's always in a charged state, so it's convenient to use in an emergency or when needed. it can.

[0021]   Furthermore, the light of this invention, when powered by the car battery, The elapsed time display section shows the time elapsed since the power was supplied. It is possible to know the elapsed time from the time when-is turned on. Therefore, the While displaying the overtime, it can also be used as a car accessory that does not get bored during warm-up operation. Can be utilized.
