Description

Multifunctional bicycle lighting device

The utility model relates to a kind of lighting device on bicycle, particularly a kind of multifunction bicycle illumination equipment.

At present, employed lighting device on bicycle has two series products in the society, and a class is the illumination equipment by bike tyre triboelectricity band electrical generator, and another kind of is the illumination equipment of dress dry storage battery or chargeable battery.Though they have many advantages to have brought many facilities for our daily life, weak points such as function singleness, use cost height, capacity are little are arranged also.

The purpose of this utility model will provide a kind of multifunction bicycle illumination equipment exactly, it not only has bicycle lighting, torch, direct supply and family's emergency lighting four big functions, and deficiency many with function, that advantages such as capacity is big, use cost is low, energy-saving safety have remedied existing usefulness lighting device on bicycle, for the both urban and rural residents provides a kind of desirable daily life tools.

The utility model is achieved in that it is made up of shell, belt clamp, battery, mounting, cap part and charging and dc output circuit.Charging jack and direct current output jack are arranged on its housing face-plate, and mounting can directly be fixed on the handlebar.This device,, can directly be installed on the handlebar when being used for bicycle lighting as power supply with lead-acid battery, can pull down at any time as torch again because of it is small and exquisite and use.When being used for direct supply, can be from direct current output jack output DC source, this product also is furnished with the 6W power saving fluorescent lamp, breaks away from this product at ordinary times, can be assembled into one when needs and do emergency lighting.

The utility model has following advantage: 1, multiple functional, can provide many convenience for daily life; 2, use is simple and reliable; 3, function, safety, arrival is convenient to pull down behind the destination; 4, provide one can carry direct supply capacious for field work, tourism.

Below in conjunction with accompanying drawing the utility model is described in further details.

Fig. 1 is a multifunction bicycle illumination equipment master cross-sectional schematic.

Fig. 2 is that the A of multifunction bicycle illumination equipment Fig. 1 is to cross-sectional schematic.

Fig. 3 is that the B of multifunction bicycle illumination equipment Fig. 1 is to scheme drawing.

Fig. 4 is a multifunction bicycle illumination equipment power principle scheme drawing.

With reference to Fig. 1, Fig. 2, Fig. 3.The multifunction bicycle illumination equipment is made up of shell (1), lead-acid storage battery (2), bulb (4), reflection shield (5), face glass (6), belt clamp (8), mounting (9) and charging and direct supply output circuit.

Shell (1) adopts engineering plastics to make, and profile is a cuboid, and the circular arc design is adopted on turning and surface, makes it handsome in appearance, holds comfortable.It is of a size of long 13～15cm, widely is≤6.8cm, thickly is≤3.6cm.The bottom of shell (1) directly is injected with fixed cover (7), (11).Fixed cover (7) seals all around, the rear and front end opening, and there is a dividing plate centre, and the front end cavity cooperates with the elastic tip of mounting (9) and can be fixed on the handlebar, and the rear end cavity is used for card belt clamp (8).Fixed cover (11) is around one and front end seals the only cavity of open rearward end, and it only is used for and vehicle frame (9) matches, and illumination equipment is fixed on the handlebar.There is a source switch (13) the front end side of shell (1), and front panel has direct current output jack (14), charging jack (15), charging indicator light (16).For ease of maintenance, shell (1) is made two parts and is combined, and adopts the convex edge groove to be connected between them.

Lead-acid storage battery (2) is two lattice, and voltage 4V adopts colloidal electrolyte, is fixed in the shell (1) by screw (3) with flathead screw.

Bulb (4) be commercially available 3.8V small bulb, reflection shield (5) all with generally the torch reason is identical for square, glass baffle plate (6) wait, do not giving unnecessary details.

The material of belt clamp (8) is ABS plastic or elastic steel sheet, snaps in the rear chamber of fixed cover (7) to be connected, and the time spent can not dial down.

Mounting (9) is made with elastic steel sheet, is about 10cm, and wide is 3～4cm.Its middle part has a fixed card (10) to be used for a mounting (9) to be fixed on the bicycle handle bar.Its rear and front end, top is inserted preceding cavity and (11) cavity that shell (1) is gone up fixed cover (7) respectively, with the built in light device.

With reference to Fig. 4.The charging of multifunction bicycle illumination equipment and dc output circuit are by diode D ₁, light-emitting diode D ₂, bulb D, battery E, K switch and charging jack and output jack form.

Diode D ₁With light-emitting diode D ₂After the same polarity parallel connection, its anodal end with the movable reed end in charging hole with direct current delivery orifice a is connected, and the end charging hole movable contact end of negative pole and bulb D and the positive pole of battery E join.Be attempted by the two poles of the earth of battery E after bulb D and the K switch series connection.The negative pole of battery E, direct current output b end and the equal ground connection of charging hole fixed end.

The principle of work of this circuit is: during normal operation, D is bright for the K lamp that closes a switch.During charging, charger can directly be used commercially available small transformers, and plug inserts the charging jack, and charging activity reed separates with movable contact, and electric current is through D ₁, E to ground to battery E charging, this moment D ₂Luminous.When using as direct supply, to output jack a end, output jack b end negative pole direct and battery E links the positive pole of battery E through charging hole movable contact.

This circuit also has self short-circuit protection function, and the general-purpose cross plug of using during the output direct current wherein has a charging jack that can insert just, if a end of direct current output directly is linked to the positive pole of battery E, just short circuit might occur.And this circuit is owing to adopt through the output of charging jack movable contact, and when plug inserted the charging plug hole, the charging movable contact separated with reed, and no-voltage has so just been realized short-circuit protection to a end with anodal disconnection of battery E.
