Abstract
The utility model relates to a miniature generator which is suitable for small tractors, motor-driven tricycles and diesel engines. A permanent magnet rotor is designed into a rotor which can move in an axial direction and is composed of a convex wheel adjuster, a concave wheel adjuster, a guiding axle, a long threaded rod, a spring, a bearing, etc., wherein the convex wheel adjuster and the concave wheel adjuster are assembled oppositely, and the guiding axle and the long threaded rod of an inner core are connected with a bracket, the bearing, a ring sleeve, a roller and a rotor. The convex wheel adjuster is provided with a throttle operating lever. The rotor can be correspondingly driven to move in an axial direction to regulate the intensity of a magnetic field to steady voltage when an accelerator is stepped with proper force. The utility model thoroughly solves the problems that lamps of a miniature generator can not light or is weak during low speeds; bulbs of a miniature generator can be burnt easily during high speeds.
Description
The utility model is applicable to microgenerator.
Work light power supply on baby tractor, motor tricycle, the diesel engine is general is all powered by the microgenerator of permanent magnetism class or two-end structure.This class generator is to utilize diesel engine to rotate, velocity of rotation changes greatly during the motor vehicle operation, so just cause the generator output voltage excursion bigger, produced diesel engine voltage that sends when low-speed running and do not reached demarcation 12V (actual measurement is generally all low, about 6V); At this moment dark lighting or do not work, diesel engine output voltage when running up exceeds standard, easily the scaling loss bulb.Because of this situation exists always, so that many baby tractors, motor tricycle etc. often can't be turned on light.
The purpose of this utility model will solve above-mentioned existing problems exactly, and a kind of stable-pressure device of microgenerator output voltage can stablize friction speed the time is provided.
Cardinal principle of the present utility model is exactly the power in the magnetic field of regulator generator, and generator output voltage is stable during with the realization different rotating speeds.Generator magnetic regulating device and generator are integrated, make it simple in structure, regulated output voltage effectively.
The technical scheme that realizes the design is that permanent magnet rotary 10 is designed to can be axially movable, the axis of guide 4 is fixed on the support 12, the recessed adjuster 3 of taking turns is fixed on the support 12, be connected with the axis of guide 4, one end is connected by nut 13, long bolt 6 passes the axis of guide 4, one end connects annular cover 5, the other end is by nut 14 fixedly connected cam adapter 2, cylinder 15 endoporus and bearing 7 interference fit, bearing 7 endoporus and the axis of guide 4 movingly, on the axis of guide 4, between support 12 and the bearing 7 cylindrical spring 8 is housed, cylinder 15 is fixedlyed connected with permanent magnet rotary 10, hydromagnetic iron rotor 10 endoporus and bearing outer ring interference fit, and bearing 7 endoporus and stator axis 20 are movingly, one cylindrical spring 18 is housed between the step of stator axis 20 and the bearing 17, between bearing 7 and the nut 9 spring 19 is housed.
The power control connecting rod is housed on the cam adapter 2.
The helicoid of cam adapter 2 and cam adapter 3 or inclined-plane are 10 °～1.35 °.
Concave, convex wheel adjuster partly also can adopt the mode of square sloped surface automatic centrifugal adjuster.
The utility model since the regulator generator changes of magnetic field adapting to different rotating speeds, thereby the electricity that makes generator under different rotating speeds, send all be stabilized in about 12V, thoroughly solved microgenerator for a long time the low speed lamp do not work or exceed standard at a high speed and burn the problem of bulb.Make driving safer, night running is more convenient, and economic benefit and social benefit are more widely arranged.
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is recessed adjuster 2 and the recessed schematic diagram of taking turns adjuster 3 of taking turns.
From Fig. 1 right side to see that permanent magnet rotary 10 and cylinder 15 are interference fit.Throttle on the tractor is connected with QUADRANT 1.QUADRANT 1 is contained on the cam adapter 2, the dynamics of stepping on the gas varies in size during driving, it is also different that QUADRANT 1 drives cam adapter 2 rotational angles, because cam adapter 2 and the recessed adjuster 3 of taking turns are that pairing is assembled, convex surface and concave surface that one same screw inclined plane degree is respectively arranged, and the recessed adjuster 3 of taking turns is fixed on the support 12, so the action of cam adapter 2 can only be moved vertically.Because long bolt 6 is fastening, the angle that cam adapter 2 is rotated when stepping on the gas great efforts is big, it is also big to leave recessed distance of taking turns adjuster 3, simultaneously through long bolt 6 actions, pulling cylinder 15 and permanent magnet rotary 10 move axially to left side support 12 directions together, rotor 10 is just far away from magnetic field, and the voltage that magnetic field intensity just weakens generator can not raise simultaneously; When the dynamics of stepping on the gas hour, cam adapter 2 with recessed take turns adjuster 3 near or fit, the distance of permanent magnet rotary 10 and stator 11 nearby or fit, at this moment through the action of long bolt 6, promoting rotor 10 moves axially to stator 11, rotor 10 is near from magnetic field, and magnetic field intensity can not weaken, and voltage still can be kept normal voltage.So just reach to regulate the purpose of magnetic field intensity burning voltage.
Rotor 10 can axially movable length be set, and an embodiment of the present utility model is designed to 4mm with the distance between rotor 10 and the stator 11.
This device will mix up generator output voltage earlier when installing, and adjustment method is to regulate the tightness that contacts of V belt and cylinder 15 on the diesel engine, when voltage reaches 12V, the minimum speed (idling) of diesel engine is not stopped burning with diesel engine be as the criterion.
The axis of guide 4 is fixed on the support 12, one end is fixed by nut 13, ring set 5 is designed to movingly with the axis of guide 4, its effect is to drive bearing 7 to move axially, when long bolt 6 actions, ring set 5 and bearing 7 move axially along the axis of guide 4 with cylinder 15, permanent magnet rotary 10, and the axis of guide 4 has also played the centering effect.Because the braking action of cover has guaranteed and can only move axially along the axis of guide 4 in 8 pairs of bearings of spring 7.Long bolt 6 makes the axis of guide 4, recessedly takes turns adjuster 3 and support 12 is connected and fixed.
Nut 14 has played long bolt 6 and has been attached thereto the ring set 5 that connects, bearing 7, spring 8, the effect of fixed positions such as cylinder 15 among the figure.The function that spring 8 resets in addition, the spring 19 that is contained in the spring 18 on the stator axis 20 and bearing 17 other ends is between rotor 10 and stator 11, can reduce the pressure of spring 8, also play thrust toward spring 8 directions, spring 18 also has the effect of cover in the grip roll 10, and the interior cover of bearing 17 can not be rotated.Nut 9 has been fixed spring 18,19 and the bearing 17 on the stator axis 20.The fixing support 12 on both sides on the base 16, also bearing whole device.
