Abstract

The utility model relates to an electric torch without a battery, which belongs to the field of illuminating tools. A handle [2] is held to drive a gear [15] to rotate. The speed is changed through a gear transmission mechanism [5], and a shaft of a miniature motor [8] is driven to reach a definite rotation speed. The miniature motor [8] can send out electric current to lead to an electric bulb [13] which is connected with conducting wires to emit light to illuminate. In the course of the reset of the handle [2], the shaft of the miniature motor [8] is driven to rotate continuously to generate continuous electric current to lead to the electric bulb to emit light continuously under the combined action of the pulling force of a spring [14] and an inertia fly wheel [7] on the gear transmission mechanism [5]. A shell body [1] and primary structure members can be made of metal or plastic material or composite material.

Description

No battery flashlight

The utility model relates to a kind of lighting apparatus, particularly a kind of no battery flashlight.

The tradition flashlight is that energy makes that small electric bulb is luminous to throw light on the battery.Owing to reasons such as power consumption in normal use the or moist electric leakages, battery needs often to change.Under certain conditions, for example in the field work as do not have the reserve battery can be for changing, just it can not play due illuminating effect.

The purpose of design of the present utility model is to provide a kind of lighting apparatus that battery provides energy that need not.

According to electrical principles: a motor also is a generator simultaneously, as long as the effect of external force makes the axle rotation of motor, then the two ends of its coil just can produce certain voltage.When therefore micromotor being communicated with small electric bulb,,, make the small electric bulb that is communicated with it luminous just then its coil two ends can produce enough voltage and currents if make the axle of micromotor reach certain rotating speed.

Scheme task of the present utility model and feature: non-with the handle that can hold and one; Ring gear and connecting rod form a quadric chain, wherein the ring gear of non-circle is meshed with a fixing gear; When holding fixed handle, drive the said gear rotation, and make a miniature electric arbor rotation that connects with it by a gear drive; Two connector lugs of micromotor are followed a small electric bulb with connecting wire; Above-mentioned gear drive has suitable I/O rotating ratio.Therefore, the axle of the micromotor of Lian Jieing just can reach design speed with it, and the electric energy of its generation just can make small electric bulb luminous, and plays the effect of illumination through optically focused.And the inertial flywheel with constant weight is installed in gear drive, handle because of the effect of spring under return and hold next time before in the of short duration batch process, be driven to rotate rotary inertia that the back produces of this flywheel can drive the miniature electric arbor and continues rotation incessantly, and producing continuous electric current, that small electric bulb is continued is luminous.

In the making, profile of the present utility model can be made into cartridge type, gun type, lamp holder adjustable type etc. or other Any shape.

Major advantage of the present utility model is: 1, and the moving generating of armrest need not battery, energy savings; 2, removed the follow-up investment of changing battery from; 3, certain resistance when holding, handle is arranged, therefore can play the effect of tempering hand muscle as spring-grip simultaneously.

Accompanying drawing is a theory structure schematic diagram of the present utility model, below in conjunction with accompanying drawing conceptual design is further specified.

As shown in drawings: the parts such as quadric chain, gear drive [5], micromotor [8] and small electric bulb [13] that no battery flashlight is mainly formed by: housing [1], by handle [2] and non-round ring gear [3] and connecting rod [4] are formed.

[7] be inertial flywheel, [10] are poly-first concave mirror, and [11] are the lamp holder lid, and [12] are glass, and [14] for being connected the spring between handle [2] and housing [1], [16] are standby small electric bulb box.

When holding fixed handle [2], promote non-round ring gear [3] motion, according to mechanical analysis, on gear ring this moment [3]

Between cingulum moving gear [15] rotation; After unclamping hand, handle [2] returns under the effect of spring [14], on gear ring [3]

Between tooth and the acting in conjunction of inertial flywheel [7] under, gear [15] will continue along former rotation direction rotation.Drive gear [9] rotation fixing through the output gear [6] on the gear drive [5], make micromotor [8] send electric current, make small electric bulb [13] luminous by lead with the miniature electric arbor.

When holding fixed handle [2] when reaching the limit of the position, on gear [15] and the gear ring [3]

Between tooth be meshed, when handle [2] was got back to initial position before holding, gear [15] and gear ring [3] also returned to the relative position when initial, i.e. gear [15] and gear ring [3]

On tooth engagement.Mutual initial angle in the quadric chain that handle in the design [2] and non-round ring gear [3] and connecting rod [4] are formed can guarantee the dead angle can not occur between the scope ring gear [3] of handle [2] motion and gear [15].

Use when finishing to hold fixed handle [2] no longer continuously, handle [2] is got back to initial position, and the effect of spring [14] is stopped the rotation gear [15], and micromotor [8] no longer produces electric current, and small electric bulb [13] just extinguishes simultaneously.

Inertial flywheel [7] and spring [14] are made of metal, and housing [1], handle [2], non-round ring gear [3], connecting rod [4], gear drive [5], lamp holder lid [11] can be made by metal, polymer or composite.

Small electric bulb [13] then can omit optically focused concave mirror [10], lamp holder lid [11] and glass [12] as selecting the light-focusing type small electric bulb for use.

Two parts before and after can being divided into during housing [1] is made are integral by being threaded after internal structure installs again.Housing [1] covers between [11] with being threaded with lamp holder.
