Abstract
The self-supporting step-less angle regulator for electric fan takes motive power from the worm of the fan motor, and through the power transmission cooperation of via worm, worm gear, gear, ratchet clutch, cam oscillating rod sample detector, and pendulum bar-baffle ratchet control mechanism, the variable-torque crank in inner planetary gear structure is made to move to realize step-less angle regulation. The inner planetary gear in the circular cavity is meshed with the central gear and the eccentric pin shaft through the hole in the pressing board to revolve. The step-less gear box of double-end supported inner planetary gear transmission structure has stable and reliable mesh and is suitable for use as self-supporting step-less angle regulator for electric fan.
Description
Technical field
The present invention relates to the angle pendulum regulating mechanism of electric fan, especially a kind of electric fan self-acting type stepless angle modulation apparatus.
Back of the body border technology
In the prior art, the patent No. is the invention of ZL89100824,1 oscillation angle adjuster for electric fan, showed a kind of self-powering type pivot angle adjusting gear case apparatus, referring to original text as can be known this pivot angle regulating tooth roller box obtain angle modulation motive force by the fan electromotor worm screw,---worm gear---gear transmission transfer mechanism that passes through worm screw,---fork sample detecting device, fork---concerted action of baffle plate ratchet control mechanism through click clutch, cam, but drive the crank-motion of planetary gear train displacement, and reach the purpose of electric fan self-acting type angle modulation.But, because but the planetary gear train displacement crank mechanism of mentioning in the original text only shows wherein a kind of external tooth planetary gear structure pattern, but this kind external tooth planetary gear train displacement crank is meshed with central gear on planet carrier by the single-ended cantilever arrangement of planet axis by planet wheel, influenced by the cantilever action power of the eccentric pin shaft of planet wheel other end assembling, this external tooth planetary gear structure mode in use often produces abnormal dislocation, displacement, even local part breaking, cause the self-powering type angle modulation malfunctioning.In addition, but the concrete dependency structure form of showing another kind of inner gear planetary displacement crank is not arranged in the original text, obviously, the structural type that the single-ended cantilever structure of this outer gear planetary wheel is formed is need be improved.
Summary of the invention
The object of the invention be to provide a kind of reliably, be difficult for producing dislocation, the malfunctioning and electric fan self-acting type stepless angle modulation apparatus that damages.
The present invention includes housing, worm screw---worm gear---reduction gears mechanism, the click clutch, cam---swing-bar mechanism, fork---push pedal ratchet control mechanism, hollow shaft, central shaft, central gear, connecting rod and planet carrier, be shaped on cylindrical cavity in the planet carrier of hollow shaft lower end, inner gear planetary is housed in the cylindrical cavity, inner gear planetary and central gear engagement, inner gear planetary outside end face has eccentric pin shaft, pressing plate is arranged below the planet carrier, pressing plate is encapsulated in inner gear planetary in the cylindrical cavity of planet carrier, pressing plate has through hole, and eccentric pin shaft passes through hole and can make the circumference cycle rotation in through hole.Above-mentioned through-hole diameter is slightly larger than the eccentric pin shaft diameter and adds crank maximum eccentricity sum, and less than the inner gear planetary external diameter.

Embodiment
With embodiment and accompanying drawing the present invention is described in further detail below:
With reference to Fig. 1, Fig. 2, the present invention includes housing (19), worm screw (7)---worm gear (16)---gear (5) reducing gear, the click clutch, cam---swing-bar mechanism, fork---push pedal ratchet control mechanism, hollow shaft (17), central shaft (18), central gear (16), connecting rod (13) and planet carrier (9), be shaped on cylindrical cavity (10) in the planet carrier (9) of hollow shaft (17) lower end, inner gear planetary (11) is housed in the cylindrical cavity (10), inner gear planetary (11) and central gear (16) engagement, inner gear planetary (11) outside end face has eccentric pin shaft (14), pressing plate (12) is arranged below the planet carrier (9), pressing plate (12) is encapsulated in inner gear planetary (11) in the cylindrical cavity (10) of planet carrier (9), pressing plate (12) has through hole (15), through hole (15) slightly larger in diameter adds crank maximum eccentricity sum in eccentric pin shaft (14) diameter, and less than inner gear planetary (11) external diameter, eccentric pin shaft (14) passes through hole (15) and can make the circumference cycle rotation in through hole (15).Thereby constituting one group adopts the inner gear planetary structure to form variable electric fan self-acting type stepless angle modulation apparatus apart from crank.Its working procedure is as follows: motor power is by worm screw 7, and worm gear 6, worm-wheel shaft 8 drive gearwheel 5 rotations.Put the spatial position of having decided breach 3 by the displacement that the adjusting knob (not shown) on the control panel is made in the certain limit baffle plate 4, promptly imported given signal to regulating system; Being conditioned object---crank length is taken a sample by cam swing mechanism, amplification by fork 2 also is reflected on the baffle plate 4 by the free end position of fork 2, baffle plate 4 itself is again a comparator, it is by the difference of computing to sampled value and setting value, when sampled value is consistent with setting value, fork 2 positions overlap with breach 3 positions, at this moment fork 2 whenever circle all must be by breach and do not stopped, if sampled value is different with setting value, its free end was blocked by plate washer 4 when fork 2 forwarded on plate washer 4 positions, rush open the clutch of support block 1 immediately and central shaft 18 is rotated, cause that inner gear planetary 11 changes crank length around central gear 16 actions, thereby change the pivot angle of electric fan.Meanwhile, 2 swings of cam drive fork are slided fork 2 free ends on baffle plate 4 edges, constantly make comparisons on baffle plate 4 with new sampled value and setting value.Because cam profile is continuous, so no matter the change of setting value is to increase or reduce, sampled value finally can account for the setting value unanimity, at this moment fork 2 free ends find breach 3 and pass through breach 3, thereby discharge the central shaft 18 be braked and engaging clutch again, so fan is with new pivot angle operation.Because the engagement of inner gear planetary (11) and central gear (16) almost is that face contacts, and improves the bearing capacity of planet wheel transmission greatly; And inner gear planetary (11) adopts cylindrical cavity (10), and pressing plate (12) two-end bearing support structure has bigger rigidity than the single-ended cantilever structure of outer gear planetary wheel, thereby can realize high positive drive.In shake the head operation and pivot angle adjustment process, also be not easy to misplace even be subjected to unusual impact force, displacement and damage parts, its operation is steadily reliably all the time.
The present invention can realize electric fan self-acting type stepless angle modulation, and its engagement is reliable and stable, is adapted at using in all kinds of electric fans.
