Description
【Technical field】
The present invention is related to a kind of moulinet structure, espespecially a kind of with reaching preferable braking effect and commonality fan high
Brake structure.
【Background technology】
In many consumer products, fan is main radiating instrument.When system temperature is too high, fan can start to drop
Low total system temperature, reaches radiating purpose, and when system temperature drops to a particular value, fan can stop action.And it is traditional
On will not be burnt because temperature is too high in order to avoid total system, it will usually install a radiator fan additional in system and protected
Shield.However, for the radiating in response to the more and more faster element of arithmetic speed, rotation speed of the fan requires meeting more and more higher, therefore, cause wind
After fan power-off, fan can just stop completely after still continuing coasting for a period of time.
So the known existing brake technique of DC fan is mainly being realized with circuit board, form probably has two kinds：The first
For upper electric brake is realized with software program, the microprocessor (MCU) of fan controls the H type bridges of a motor drive circuit when upper electric
Two underarm MOS electric crystals of formula (H-Bridge) are normally opened, operate the plural flabellum of the fan and produce magnetic field, the magnetic with magnetic stripe
Produce resistance and reach the effect of brake, second is to realize in hardware for power interruption braking, such as using capacitance energy storage dress
H types bridge-type (H-Bridge) of its inner motor drive circuit of fan are supplied to when being placed in power-off, make two MOS electric crystals of underarm normal
Open, the two ends for allowing H type bridge-types to connect a motor coil of the fan form short circuit, motor magnetic pole is produced change and is reached
Braking action.
So known fan brake technique must in designed on the original circuit board of fan increase extra braking circuit or
Microprocessor of the installing with brake mode function can just have braking action, but be braked only through aforementioned circuit brake modes
The plural flabellum stalling that will slowly can be operated, cannot but accelerate to allow flabellum to stall.Additionally, a series of original electricity of fans in office
On the plate of road outside existing existing function, increase braking circuit to reach during braking effect to extra again, because of any serial wind
The early cabling connection line printed between each electronic component on original circuit board of fan, so that cause cannot be direct
The braking circuit is increased on original circuit board so that dealer must be again changed on original circuit board using a new boards
Design, braking circuit can just be added, thus known fan brake aforesaid way commonality it is relatively low.
【The content of the invention】

Lower movement, meanwhile, the other end in the magnet valve axle center 2222 supports the elastic component 2221, the elastic component 2221 is in compression shape
State (such as Fig. 3), now plural first tooth 2111 of the braking parts 211 of plural second tooth 2211 and first of second braking parts 221
Be separated and without produce braking action (such as Fig. 2,2A).And when foregoing fan 1 is powered off, the magnet coil 2227 can also stop connecing
Power supply is received, is made the magnet valve body 2224 that magnetic force is not lost by excitatory and is supplied, the power for supporting elastic component 2221 is disappeared, and make the bullet
Property part 2221 by compressive state recover and provide an elastic force, the magnet valve axle center 2222 is pushed through the elasticity of the elastic component 2221
Move and return back to the magnet valve body 2224 not by excitatory real position, while second braking parts 221 also can be with the magnet valve axle center
2222 by the resilient force of the elastic component 2221, and is moved up towards the direction of relative first braking parts 211, make this second
Plural second tooth 2211 of braking parts 221 with to should the first braking parts 211 plural first tooth 2111 be meshed (such as Fig. 2 B,
2C), the effect for reaching braking action is used.
Another person, an at least confinement groove 2226 is provided with foregoing magnet valve body 2224, and the confinement groove 2226 is by the hole
The 2225 recessed compositions in inner side, and the hole 2225 is connected, the outer circumferential side of magnet valve axle center 2222 is provided with a limitation convex body 2223, the limit
Convex body processed 2223 is inserted into the confinement groove 2226, with limit the limitation convex body 2223 in the confinement groove 2226 up,
Lower direction movement.And the support 23 is provided with a projecting ring section 231 and a card division 232, the projecting ring section 231 is located on the outer of the support 23
In the week side of boss, and a side surface of the projecting ring section 231 is close to close in the bottom outside of the axle bed 111, and the card division 232 is by the branch
One end of frame 23 protrudes out composition, and the card division 232 and phase clamping at the second opening 114 of the relative axle bed 111 upwards, makes the branch
