In order to address the above problem, the objective of the invention is, even provide a kind of external force to act on the wind direction adjustment means, can not make stepper motor impaired yet, in case disappearing, external force can make the wind direction regulating device of the original wind direction angle of wind direction adjustment means recovery.
Wind direction regulating device provided by the invention comprises:
The power generating apparatus that the driving force that rotates is used,
The intermediary that the driving that is connected with the output shaft of described power generating apparatus by an end is cranked arm and by the power transfer member of the rotating drive masterpiece straight reciprocating motion of described power generation arrangement, and,
The straight reciprocating motion of described power transfer member is converted to rotational motion and makes the wind direction adjustment means that is installed on the one side carry out the power-supply change-over member that wind direction is regulated,
It is characterized in that:
The top of described power transfer member offers the gathering sill that there is peristome at two ends, is provided with protuberance between described both ends open portion, and the other end that described driving is cranked arm is inserted in the described gathering sill, simultaneously,
Disposing respectively under reaching on the other end is cranked arm in described driving can be along the 1st sliding component and the 2nd sliding component of described gathering sill slip, and the described the 1st and the 2nd sliding component interconnects by elastic component in described gathering sill, and,
Be set at rotating drive power for making the external force that acts on described wind direction adjustment means be absorbed elastic force with described elastic component less than described power generating apparatus by described elastic component,
Constitute location and the resetting means that makes described power transfer member and the interlock of the described the 1st and the 2nd sliding component elasticity by described gathering sill, described protuberance, the described the 1st and the 2nd sliding component and described elastic component.
Power generating apparatus comprises stepper motor, and the output shaft of this stepper motor links to each other with the end that driving is cranked arm, and the other end that this driving is cranked arm is connected with power transfer member.The wind direction adjustment means places the framework front that is provided with air outlet, because the rotational motion of the power-supply change-over member that is connected with the bottom of power transfer member, the wind direction adjustment means rotates between upright position and horizontal level to regulate wind direction.
The bottom of the carriage between power transfer member and framework is installed in the outside of framework, on the top of this carriage stepper motor is installed.The top of power transfer member offers gathering sill, and there is peristome at the two ends of this gathering sill, and the both sides of the middle part of gathering sill are formed with protuberance.The end that driving is cranked arm is connected with the driving shaft of stepper motor, and the other end is inserted in the gathering sill between above-mentioned protuberance.
Location and resetting means comprise the 1st and the 2nd sliding component that is positioned at the upper and lower sides that above-mentioned driving cranks arm, and the elastic component that elasticity such as this sliding component is connected, and the above-mentioned the 1st contacts with lower surface with the upper face that driving is cranked arm respectively with the 2nd sliding component.One end of power-supply change-over member is installed on the bottom of power transfer member, and the other end is connected with the side of wind direction adjustment means.
The action of the present invention of said structure is as follows: at first, be in closed condition at air outlet, be that the wind direction adjustment means is when being in the state parallel with framework, the control part of the equipment at place of the present invention sends signal in order to make the wind direction adjustment means regulate certain angle, in a single day this signal is sent to power generating apparatus, the motor of power generating apparatus just moves, and driving cranks arm just rotates.
At this because the driving force of power generating apparatus is greater than the making a concerted effort of the rotatory force of the elastic force of elastic component and wind direction adjustment means, and above-mentioned elastic force be designed to bigger than above-mentioned rotatory force, so power generating apparatus can make the rotation of wind direction adjustment means.When cranking arm rotation downwards with driving, the power transfer member limit is moving linearly downwards, and the limit is rotated the power-supply change-over member downwards.Therefore, the power-supply change-over member upwards rotates the wind direction adjustment means, carries out the adjusting of wind direction by the angle that is conditioned.
At this moment, be connected by elastic component with the 2nd sliding component owing to constitute the 1st of location and resetting means, and the power that has of elastic component is greater than the rotatory force of wind direction adjustment means, so, driving is cranked arm in the gathering sill of power transfer member, rotates under the state that keeps certain position.
Specifically be, when driving is cranked arm when rotating, owing to drive the rotatory force of cranking arm, make the downward moving linearly of power transfer member, simultaneously, the part of this driving force is in the gathering sill of power transfer member, become to make and drive the power crank arm to lower slider and work, but because the interaction of the 1st and the 2nd sliding component and elastic component, this power is absorbed, driving is cranked arm and is not taken place to rotate slidably in gathering sill, makes power transfer member at correct position moving linearly.
In addition, even rotation external force up or down acts on the wind direction adjustment means, location and resetting means also make this rotation external force not be passed to power generating apparatus, prevent the damage of power generating apparatus, in case this rotation external force is removed, just make the wind direction adjustment means recover original position.
Specifically be, be adjusted under the state of the certain angle between horizontal level and the upright position in the wind direction adjustment means, when the effect of rotation external force is rotated the wind direction adjustment means up or down, this rotation external force is delivered to power transfer member by the power-supply change-over member on the contrary, but because above-mentioned location and resetting means, this external force is absorbed and the unlikely power generating apparatus that is delivered to.
For example, when the rotation external force that makes progress that surpasses elastic component elastic force acted on the wind direction adjustment means, the power-supply change-over member rotated, and makes the downward moving linearly of power transfer member.
Because the moving down of power transfer member, at the crank arm set protuberance in both sides of the gathering sill that is positioned at of driving, crank arm and be positioned under the state that the 1st sliding component on its top still stops in driving, the 2nd sliding component is pushed downwards.
Therefore, though the set angle of wind direction adjustment means changes because of rotating external force, this rotation external force is absorbed by the elastic force of elastic component simultaneously, does not rotate because drive to crank arm, so this external force is not delivered to stepper motor.In addition, remove, because the effect of the recuperability of the elastic component that is elongated in case rotate external force, above-mentioned the 2nd sliding component recovers original position, and power transfer member moves up simultaneously, and the power-supply change-over member rotates, meanwhile, the wind direction adjustment means is recovered the angle of setting.
It is big more to rotate external force, and elastic component is stretched longly more, and the interval of the 1st and the 2nd sliding component is also drawn back longly more simultaneously, and the restriction of the brake block of being given prominence to up to the power-supply change-over member stops in the time of can not being rotated further.Under the situation of rotating external force effect downwards, opposite with above-mentioned explanation, become the 2nd sliding component and fix, the 1st sliding component moves up, and direction is with above-mentioned opposite, but its effect is identical.

Below in conjunction with the description of drawings embodiments of the invention.
Fig. 3 to Fig. 6 shows according to a kind of wind direction regulating device of the present invention.Side at air-supply framework 21 offers two hole 21b that allow the 1st and the 2nd sharf 22a, 23a penetrate, and the wind direction adjustment means is the front that the 1st and the 2nd blade 22,23 is installed in framework 21.
The lateral surface that is provided with the framework 21 of above-mentioned hole 21b is fixedly attached to the bottom of carriage 24, on this carriage 24, with the identical position of above-mentioned hole 21b, offer hole 24a, the 24b roughly the same with the shape of hole 21b, the the 1st and the 2nd sharf 22a, 23a pass this hole 21b, 24a, 24b, promptly the 1st 25,26 are connected with the 2nd passive cranking arm with the power-supply change-over member respectively.Back on the top of carriage 24 is installed with stepper motor 27, and the driving shaft 27a of stepper motor 27 penetrates the through hole 24g of carriage 24, is inserted in to be opened in the slit 28a that drives 28 1 ends of cranking arm.
About the hole of carriage 24 24a, 24b and through hole 24g, be extruded with 3 couples of brake(-holder) block 24c, 24d, 24e, 24f and 24h, 24i that form through Punching Technology, they limit respectively to drive and crank arm 28 and the radius of gyration of power-supply change-over member 25,26.The front of carriage 24 is provided with power transfer member 30, and this power transfer member 30 cranks arm 28 and power-supply change-over member 25,26 supporting by above-mentioned driving, pumps owing to drive 28 the rotation of cranking arm, and makes 25,26 rotations of power-supply change-over member.The top of power transfer member 30 offers dimetric peristome 30a, 30b, and these two peristome 30a, 30b interconnect by the narrower gathering sill 30c of width.Be provided with protuberance 30e in the middle part of gathering sill 30c, driving cranks arm 28 inserts in the gathering sill 30c at these positions and rotates, and makes power transfer member 30 moving linearlies.In addition, the 1st and the 2nd sliding component 31,32 inserts by each peristome 30a, 30b of power transfer member 30, and moves to the inside along gathering sill 30c, places respectively to drive 28 the above and below of cranking arm.Be placed in the top that drives the 1st sliding component 31 above 28 of cranking arm and be placed in the bottom that drives the 2nd sliding component 32 below 28 of cranking arm, be respectively equipped with the hook projection, by this hook projection, the hook portions at elastic component 34 two ends is lived by hook, and the 1st is connected with the 2nd sliding component 31,32 mutual elasticity and moves.Reinforcement 33 is inserted in the slit 30d that is formed at protuberance 30e center, therefore when 28 rotations are cranked arm in driving, the width that can prevent gathering sill 30c causes the fault of the 1st or the 2nd sliding component 31,32 disengaging gathering sill 30c because of above-mentioned rotation external force broadens.
The bottom of power transfer member 30 offers patchhole 30f, the 30g that allows power-supply change-over member 25,26 penetrate, and the rectilinear motion of power transfer member 30 is converted to the rotational motion of wind direction adjustment means 22,23.
The action of the wind direction regulating device of the present invention of said structure is that the driving force by stepper motor 27 is driven and finishes, and stepper motor is to accept to move from the signal of the control part of the equipment that this wind direction regulating device is set.
State when Fig. 5 illustrates wind direction adjustment means 22,23 air-supply face is closed.Wind direction adjustment means 22,23 leading flanks at framework 21 are in the state of closing air outlet, drive crank arm 28 and power-supply change-over member 25,26 be placed in upwards position.Under this state, in case because the driving force of stepper motor 27, the driving shaft 27a of this stepper motor 27 begins to rotate, and then driving cranks arm 28 rotates, and makes power transfer member 30 downward moving linearlies.
At this moment, contact with crank arm 28 top or bottom of driving, and be inserted in the 1st sliding component 31 in the gathering sill 30c and the 2nd sliding component 32 because the effect of the elastic force of elastic component 34, driving cranks arm 28 in the certain position place of power transfer member 30 maintenance original position, does not take place to rotate slidably in gathering sill.Therefore, driving cranks arm 28 does not slide in gathering sill 30c, and makes extremely correct position of power transfer member 30 downward rectilinear motions.Because the downward rectilinear motion of power transfer member 30; Power-supply change-over member 25,26 rotates, and wind direction adjustment means 22,23 is upwards rotated.Therefore, wind direction adjustment means 22,23 is opened to the indicated angle of signal of control part with air outlet, carries out the adjusting of wind direction.
Shown in Figure 6ly be, when wind direction adjustment means 22,23 as shown in Figure 5, be in the following time of state of the leading flank that is parallel to framework 21, become the situation after the plumbness owing to being subjected to external force.
In case upwards rotate owing to the rotatory force from the outside makes wind direction adjustment means 22,23, then power-supply change-over member 25,26 rotates, thereby the also downward moving linearly of power transfer member 30.In case power transfer member 30 moves downward, driving the 28 and the 1st sliding component 31 of cranking arm is maintained fixed state, then begin to push the 2nd sliding component 32 downwards at the crank arm set protuberance 30e in both sides of the 28 gathering sill 30c that are positioned at of driving, elastic component 34 is elongated.At this, wind direction adjustment means 22,23 only can be rotated during greater than the elastic force of elastic component 34 at the active force that rotates external force, and the extended length of elastic component 34 is stretched longlyer along with the increase of this rotation external force strength.Therefore, shown in Figure 6 is situation when wind direction adjustment means 22,23 is the maximum rotation angle under rotating the external force effect, so be the state of elastic component 34 when stretching the most longly.
The rotation of the wind direction adjustment means 22,23 that causes by the rotation external force of the elastic force that surpasses elastic component 34, the result only makes power transfer member 30 and location and resetting means 31,32,34 move, do not pass to drive and crank arm 28, so this rotation external force can not have influence on power generating apparatus 27,28.
Have again, as shown in Figure 6, when elastic component 34 is in elongation state because of rotating external force, in case this rotation external force is removed, because the recuperability of elastic component 34, power transfer member 30 returns to original position, and wind direction adjustment means 22,23 also returns to the original position that is conditioned.
When angle that wind direction adjustment means 22,23 is between the horizontal and vertical position, under the situation that is subjected to downward rotation external force, power transfer member 30 moves up, and drive the 28 and the 2nd sliding component 32 of cranking arm and be maintained fixed, and protuberance 30e moves up the 1st sliding component 31.
Because above-mentioned effect, act on wind direction adjustment means 22,23 even rotate external force, power generating apparatus 27,28 also can not be subjected to the influence of this power, has again, in case this rotation external force is removed, wind direction adjustment means 22,23 just returns to the original position that is conditioned.
The present invention has following effect: even rotate external force from directive effect arbitrarily in wind direction Adjustment means, this external force can not be passed to power generating apparatus yet, so can prevent stepping In a single day the damage of motor prolongs its life-span, and removes this external force, the wind direction adjustment means just Can return to the position that originally was conditioned.
