Description

[Detailed Description of the Invention] The present invention relates to an improvement of a bicycle light device having a built-in battery.

In general, bicycles are often left parked outdoors, and even if the bicycle itself is locked, light fixtures alone are frequently stolen, and bicycles that are parked accidentally fall over. There was also a risk of damaging the lighting equipment.

Moreover, with conventional lighting equipment that uses only the built-in power supply as a power supply, if the power suddenly goes out while driving at night, the lighting equipment will turn off and will not turn on until the power is replenished. , which was extremely dangerous and difficult to use.

Therefore, in the present invention, an auxiliary power source S2 is built into a mounting base N that removably supports a lamp main body M having a built-in main power source S, and with the lamp main body M mounted on the mounting base N, By providing a conduction means to establish continuity between the lamp body M and the auxiliary power source S2, it can be removed from the bicycle when not in use, and even if the power goes out while riding at night, the light can be immediately turned on by the auxiliary power source. The purpose of the present invention is to provide a bicycle light that enables the use of bicycle lights.

In addition, the present invention is equipped with a solar cell that charges the built-in main power supply S□ in the main body M of the lamp.In recent years, when energy saving has become an issue, this invention charges the lamp using natural light during the day, and saves energy during the day when driving at night. It is also possible to light up the lamp using the electric power that is generated.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a diagram showing a lamp body M according to an embodiment of the present invention. 1 is a box-shaped case body with an opening 2 on the front, and a rechargeable battery S and a light bulb support plate 4 are built in. A light bulb 5 is mounted on the light bulb support plate 4, and after a reflector 6 is mounted to surround the light bulb 5, a hood 7 is removably mounted with screws 8 so as to cover the opening 2.

A solar cell 9 consisting of a photoelectron conversion element having the function of converting light energy into electrical energy is mounted on the upper surface P□ of the case body 1, and both terminals of the solar cell 9 are connected to a backflow prevention device. It is electrically connected via a diode 10 to the rechargeable battery S□ that stores electrical energy.

11 is a switch for ON/OFF switching.

Further, metal plates 12 and 12' for connection with an auxiliary power source are fixed to the rear surface P2 of the main body case 1, and supporting key portions 3 and 3' extend rearward from both ends of the rear surface P2, respectively. It is set up.

Reference numeral 22 denotes a grip part supported on the side surface of the main body case 1, and is formed to be expandable and retractable so as not to interfere with storage and to be convenient to carry.

FIG. 2 shows the configuration of the mounting base N. Reference numeral 13 denotes a box-shaped base main body that also serves as a battery storage chamber, and has a battery insertion slot 14. In this embodiment, a dry battery S2 is used as an auxiliary power source. A cover plate 19 is inserted through the opening 14 and detachably closes the battery insertion opening 14 with screws 16 in order to make the dry battery S2 replaceable.

17 is a terminal plate for battery connection attached to the cover plate 19;
．． 18' is a positive and negative picture electrode plate.

Guide grooves 15, 15' are provided along the longitudinal direction on both side surfaces Q□, Q2 of the base body 13, and as shown in FIG. Insert the key parts 3 and 3' and guide the base body 1.
With the front surface Q of 3 and the rear surface P2 of the lamp body M facing each other,
The lamp body M can be detachably supported on the mounting base N.

Further, on the front surface q of the base body 13, there is a metal plate that comes into sliding contact with the metal plate 12, 12' fixed to the rear 12 of the light body M when the light body M is attached to the mounting base N. 20
．． 20' is fixed, and the contact between both metal plates (12 and 2
0.12' and 20'), electrical continuity can be established between the dry cell battery S2 built in the mounting base and the lamp body M.

Next, in the electrical connection method of this embodiment, as shown in FIG.
is connected to the rechargeable battery S0 via the rechargeable battery S□
is connected to the light bulb 5 via the one-sided terminal T1 of the switch 11.

In addition, the positive and negative terminals of the dry battery S2 built in the mounting base N are connected to the metal plates 20 and 20', respectively, and by mounting the lamp body M on the mounting base N, the metal plate 2
The metal plates 12, 12' in contact with 0.20' are connected to the light bulb 5 via the other terminal T2 of the switch 11.

To is a neutral terminal that does not conduct electricity.

The method of using this embodiment is to fix the mounting base N to a mounting portion 21 attached to a bicycle handle stay, fork, etc., as shown in FIG.

When using at night, insert the key parts 3 and 3' into the guide groove 15.15'.
Attach the main body M of the lamp to the mounting base N while guiding it with The light bulb 5 is turned on, and if the rechargeable battery S□ is completely discharged due to long-term driving, the terminal T
When the switch 11 is operated to close the second side, the circuit powered by the dry cell battery S2 built into the mounting base N is activated, and the light bulb 5 can be turned on.

In addition, when not in use, only the light fixture M can be easily removed, which prevents theft and damage to the light fixture due to accidental falls while parking the bicycle.At night, the light fixture M itself can also be used as a hand light. It is also possible to do so.

As another embodiment, the main power supply S built in the lamp body M
1 may be a dry battery or a rechargeable battery charged by an AC power source, and the auxiliary power supply S2 built in the mounting base N may be a rechargeable battery charged by a solar battery.

Further, the solar cell 9 mounted on the lamp body M or the mounting base N may be detachable itself.

For example, it is possible to selectively attach and detach the solar cell 9 to the light fixture body M1 and the mounting base N, and when it is mounted on the light body M, the built-in main power supply S1 is used, and when it is mounted on the mounting base N, the auxiliary power supply S2 is used. may be charged.
