Specific embodiment

First core of the invention is exactly to disclose a kind of magneto assembly, to realize reducing because the micro- change of minute surface causes to throw The purpose of the generation of shadow effect on driving birds is not good phenomenon；Second core of the invention is exactly to disclose a kind of projector.Hereinafter, referring to the drawings Embodiment is illustrated.Additionally, embodiments illustrated below does not play any restriction to the content of the invention described in claim Effect.In addition, the full content of the composition represented by example below is not limited to the solution as the invention described in claim Certainly necessary to scheme.

As shown in Figures 3 to 8, the magneto assembly includes magneto 1 and the clutch being engaged with the bent axle of engine 3, clutch 3 transmits torque by connection member to the magneto 1, wherein, connection member 5 includes the fixation being connected with flywheel Seat 51, fixed seat 51 is set on the output shaft 32 of clutch, and fixed seat 51 is internally provided with the output shaft 32 with clutch 3 Frictional force with the output shaft 32 of clutch 3 is converted into the brake pad 6 for abutting against, brake pad 6 torque of fixed seat 51.

When the magneto assembly runs, the rotating speed of the output of clutch 3 is converted into the torque of fixed seat 51 for rubbed piece 6, It is ultimately converted to the torque of flywheel.When the rotating speed that clutch 3 passes to magneto 1 reaches the maximum speed of magneto 1, friction Block 6 skids with the output shaft 32 of clutch 3, the off position of magneto 1.Therefore, it is total using the magneto in the present invention Occur into the situation that magneto can be avoided to run at high speed for a long time, so as to extend the service life of magneto.

Wherein, realize that flywheel has various with the installation form of connection member 5, in the embodiment of the present invention, flywheel middle part is set The end face for having the pilot hole 11 being engaged with connection member 5, flywheel is provided with the mounting hole 12 of fixed connecting part 5.Fixed seat 51 one end is passed through in pilot hole 11, and the edge of fixed seat 51 is provided with the fixing hole 56 being adapted with mounting hole 12.

Wherein, as shown in fig. 7, being provided with the brake pad of installation brake pad 6 in fixed seat 51 along the radial position of fixed seat 51 Hole position 54, brake pad 6 is directly anchored in brake pad hole position 54, and different brake pads 6, the week of fixed seat 51 are replaced for convenience Face is removably provided with block, and block limitation brake pad 6 is moved radially, and when needing to change brake pad 6, block is dismantled Get off, it would be desirable to which the brake pad 6 of replacement is replaced, and then reinstalls block.

In addition, being additionally provided with driving brake pad 6 edge to be provided with cost-effective fixed seat 51 on the position of brake pad 6 The gear regulating member 8 for moving radially of the output shaft 32 of clutch 3.Specifically, the gear regulating member 8 is adjusted installed in gear In section part hole position 55.In the presence of gear regulating member 8, brake pad 6 can be driven to be moved near the direction of output shaft 32 It is dynamic, after the abrasion of brake pad 6, brake pad 6 is ordered about in the presence of gear regulating member 8 and is moved near the direction of output shaft 32 It is dynamic such that it is able to so that brake pad 6 continues to continue to contact with output shaft 32.

Gear regulating member 8 includes spring and housing screw, housing screw and fixation in one embodiment of the invention 51 screw threads of seat coordinate, and spring is located between housing screw and brake pad 6.In another embodiment of the present invention, gear regulation Part 8 is magnetic valve.

In addition, the frictional force between reducing the output shaft 32 and fixed seat 51 of clutch 3, fixed seat 51 is defeated with clutch Bearing 7 is additionally provided between shaft 32, the position that fixed seat 51 is provided with bearing 7 is bearing hole position 53, the bearing hole position 53 In the side of centre bore 52, centre bore 52 is used to install output shaft 32.

For stress balance, the quantity of bearing 7 is two, and two bearings 7 are located at the both sides of brake pad 6.

Clutch 3 include body 31 and output shaft 32, wherein, the middle part of output shaft 32 is provided with roughness 322, for Brake pad 6 is engaged, and the end of the output shaft 32 of clutch 3 is additionally provided with bolt hole 323, for fixing magneto 1.

Idling stage, magneto 1 causes that magneto 1 reaches the full car in addition to rechargeable battery charges by the cooperation of connecting portion Rotating speed corresponding to maximum power consumption.With the rising of rotating speed, the generated output of magneto 1 is also in rising, but elevated amplitude It is less and less, the holddown spring under certain rotating speed under own wt effect of brake pad 6, and in the state of not holddown spring, The magneto 1 for losing frictional force is to slide relative to output shaft 32.

After the rotating speed of magneto 1 declines, brake pad 6 pushes output shaft 32, replys frictional force, the rotating speed liter of magneto 1 Height, presses on brake pad 6, so that magneto 1 remains at a fixed rotary speed area, no longer with engine drilling speed liter It is high and raise, solve the waste of the kinetic energy of magneto 1.

The weight of magneto 1 is smaller, therefore frictional force required for brake pad 6 is smaller, and durability preferably, is using one section After time, by adjusting clamp nut by be continuing with.

Magneto 1 is limited in fixed rotary speed area and uses so that temperature is relatively low and vibrations are smaller, and temperature and shake Dynamic is the demagnetization reason of magnetic element, therefore, can extend making for magneto 1 using the magnetoelectricity thermomechanical components in the embodiment of the present invention Use the life-span.

Meanwhile, the opposite engine of magneto 1 is maintained in a level for low speed, is solved unnecessary kinetic energy and is wasted.

The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention. Various modifications to these embodiments will be apparent for those skilled in the art, as defined herein General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, the present invention The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one The scope most wide for causing.
