Divide and enter within concave part 15A.In this way, the maximum rotation angle of door body can be slightly larger than the angle of 180- α 1.
Fig. 8 shows the internal structure of door body rotating mechanism 10 according to an embodiment of the invention.Wherein, door body rotating machine
The extension 15 of structure 10 is linear, and correspondingly, the three-level end gear 13,123,127 inside extension 15 is linear
Arrangement.Fig. 9 shows another embodiment, wherein, the extension 15 of door body rotational structure 10 is near linear shape, correspondingly,
Three-level end gear inside extension 15 is arranged near linear.Specifically, most end two-stage gear is in line arrangement, and
Level gear third from the bottom is offset up.Comparatively speaking, the structure of the door body rotating mechanism of Fig. 9 is more compact, and the door body of Fig. 8 rotates
The extension 15 of mechanism is more elongated, is applicable to thicker door body.
As shown in figure 8, door body rotating mechanism 10 includes driving motor 110, transfer gear train 120 and output shaft 13.Driving
Motor 110 drives output shaft 13 to rotate via transfer gear train 120.Slow down by transfer gear train 120, output shaft 13 can be defeated
Go out high torque, so as to drive door body synchronously to rotate to realize switch gate.
In a particular embodiment, noise can obviously reduce as driving motor 110 using stepper motor.After tested, it is conventional
The noise of brush direct current motor in itself is in 40dB or so；And the noise of stepper motor can be in below 31dB.Therefore, using stepping
Motor can provide quiet usage experience to the user for driving source by fundamentally reducing complete machine noise.In addition, and DC brush
Motor is compared, and stepper motor can realize fine rotational control.The driver of stepper motor can provide driving pulse exactly, and
Motor can make corresponding actions according to umber of pulse, so as to export accurate turnning circle or angle.In a particular embodiment, may be used
Synergistically to control the stepper motor of the stepper motor of door body rotating mechanism and corresponding roof door mechanism so that roof door mechanism applies
The output speed of the initial speed and rotating mechanism that are added on door body matches, such as roughly equal, to allow door body rotating machine
Structure swimmingly intervenes the rotation of door body.
110 output torque of motor is transferred to output shaft 13 by transfer gear train 120.Transfer gear train 120 can include from
Mechanism 121 is closed, as shown in Figure 10.The effect of clutch 121 is, when needing rotating mechanism 10 to work, operates clutch
Structure 121 enters engagement, so that power transmission of the motor 110 to output shaft 13 is connected, so as to fulfill automatic switch refrigerator
Door body；When being not required rotating mechanism 10 to work, operation clutch 121 enters discrete state, so as to cut off motor 110 to defeated
The power transmission of shaft 13, so as to allow components downstream to be freely rotated, then allows user to manually turn on or closing refrigerator door
Body.In this way, switching between automatic mode and manual mode can be realized by operating clutch 121, to meet user's
Different demands.
Clutch 121 can include clutch gear 121A, brake spring 121B and slide bar 121C.Clutch gear 121A bags
Include and be wholely set gear piece LC1 and tooth shaft LC2, gear piece LC1 is optionally engaged to the mate gear of upstream, such as motor gear
124 or it is connected to the transition gear 125 of motor gear 124.Tooth shaft LC2 is rotated together with gear piece LC1, and is engaged to down all the time
The mate gear of trip, such as slipping gear 122 or other gears.
As shown in figure 11, it is arranged between the upper surface of clutch gear 121A and lid 140 brake spring 121B biass,
So as to apply a downward spring force for clutch gear 121A.Clutch gear 121A can slide up and down along its gear shaft 121E.
Also, slide bar 121C can be moved horizontally, it is arranged between the lower face of clutch gear 121A and housing 150.As shown in the figure,
The left side of slide bar 121C has inclined-plane, its right side is connected to the push rod of electromagnet 121D via a U-lag.
As shown in figure 11, when electromagnet 121D is not powered, the push rod of electromagnet 121D is free, at this time, with it
The slide bar 121C of linkage can freely left and right sliding.At this time, brake spring 121B biass clutch gear 121A is moved to most lower
The separation point position of side.In separation point position, as shown in figure 16, the gear piece LC1 of clutch gear 121A and neighbouring transition gear 125
Stagger longitudinal direction.Also, the lower end of clutch gear 121A promotes slide bar 121C to move to right final position to the right.
As shown in figure 12, when electromagnet 121D is powered, the push rod of electromagnet 121D is moved to the left under magneticaction,
At this time, the slide bar 121C to link with it slides certain distance to left final position to the left.At this time, the inclined-plane on the left of slide bar 121C is strong
Between the lower end of system ground insertion clutch gear 121A and housing 150.Thus, the inclined-plane of slide bar 121C can promote clutch gear
121A is moved upward to the position of engagement of the top, and overcomes the bias effect of brake spring 121B.In the position of engagement, such as
Shown in Figure 17, the gear piece LC1 of clutch gear 121A is engaged with neighbouring transition gear 125.In addition, as shown in the figure, clutch gear
Chamfering is provided with the cylinder that the bottom of 121A coordinates with slide bar 121C, so as to the inclined-plane insertion clutch gear 121A of slide bar 121C
Between housing 150.Moreover, in order to ensure gear piece LC1 is smoothly engaging-in or disengages, in the upper end periphery of gear piece LC1 and neighbour
Chamfering is both provided with the lower end periphery of near transition gear 125.
As long as electromagnet 121D is not powered off, slide bar 121C is positively retained at left final position, and keeps at clutch gear 121A
In the position of engagement.After electromagnet 121D is powered off again, the retentivity on slide bar 121C disappears, the clutch bullet compressed before
The spring force of spring 121B pushes down on clutch gear 121A, it is returned back to the separation point position of bottom, and via clutch gear
121A promotes slide bar 121C to return back to its right final position.
Figure 13 shows the example arrangement of slide bar 121C.The left side inclined-plane of slide bar 121C is equipped with another U-lag, the U
Shape groove is used for the gear shaft 121E for avoiding clutch gear 121A.Therefore, when slide bar 121C is slided to the left, the inclined-plane of slide bar 121C
It will not be interfered with gear shaft 121E.In addition, the middle position of slide bar 121C is equipped with guiding groove, the spiral shell of trip bolt 121F
Bar part is screwed to the housing 150 of lower section through the guiding groove.As shown in FIG. 11 and 12, during slide bar 121C horizontally slips,
The screw portion of trip bolt 121F slides in the guiding groove of slide bar 121C.Since guiding groove is linear so that slide bar
The slip of 121C keeps rectilinear direction.In addition, the size of the nut portion on the upside of trip bolt 121F is more than the transverse direction of guiding groove
Width so that nut portion can provide the stability force of vertical direction for slide bar 121C.Thus, slide bar 121C is being promoted to put down to the left
During shifting, the left side inclined-plane of slide bar 121C will not occur to tilt and lead to not be inserted into.In addition, the seal face and slide bar of nut portion
121C must retain a gap, such as 0.2mm, to avoid hindering the slip of slide bar 121C.In addition, in order to further allow
Slide bar 121C is smoothly slided, and concave slide bar guide groove is set on housing 150, as shown in figure 14, to guide slide bar 121C to exist
Along rectilinear movement in guide groove.Moreover, guide groove bottom is provided with convex ribs, for preventing the bottom surface of the bottom surface of slide bar and guide groove
Larger resistance is produced in the case of being fitted in grease.
It may be noted that no matter clutch gear 121A is in discrete state or engagement, the tooth on the downside of clutch gear 121A
Axis LC2 needs to keep engaging with the slipping gear 122 in downstream.For this reason, the width of tooth shaft LC2B need to be more than the width of slipping gear 122
Degree.Moreover, when clutch gear 121A is in discrete state, tooth shaft LC2 has an end tooth to be located at more than slipping gear 122 under it
Side, it is wide enough between tooth shaft LC2 and slipping gear 122 to nibble so as to when moving to engagement on clutch gear 121A
Close tooth.
As shown in Figure 10, transfer gear train 120 can also include sliding mechanism 122.The effect of sliding mechanism 122 is,
When the transmission moment of torsion of sliding mechanism 122 is more than breakaway torque, sliding mechanism 122 occurs to skid and cut off moment of torsion transmission, so that
Motor 110 and other components is protected to be damaged from external impacts.
The refrigerator door rotating mechanism of the present invention can use split type sliding mechanism 122.Split type sliding mechanism is with showing
Some friction plate sliding mechanisms are significantly different.As Figure 18 shows existing friction disk type sliding mechanism P, wherein, pre-loading screw
P1 compresses end cap P2 to produce axial pressing force, forces the metal friction piece P3 of gear piece P4 both sides to deform, thus with gear piece P4 it
Between produce lasting normal pressure.When the transmission moment of torsion between gear piece P4 and axis tooth P5 is more than the stiction that the normal pressure produces,
Sliding mechanism P starts to skid.When after initially skidding several times, the roughness of friction plate P3 reduces, and causes slipping torque fast
Prompt drop is low.Limited by friction plate material and technique, the slipping torque value of this sliding mechanism P can not accomplish very greatly, generally to exist
2kgfcm or so.Therefore, the level of refrigerator door can be turned in order to reach the torque of output shaft 13, it is necessary to friction plate
Formula sliding mechanism P is placed on close to the position of motor 110 in power train, such as at the second level or third level gear.However, at this
In the case of kind, the fluctuation of slipping torque caused by sliding mechanism foozle in itself and rigging error etc. can be put by power train
Output shaft 13 is transferred to greatly, output torque is produced and fluctuates and cause significant vibration and noise.
The sliding mechanism 122 of the present invention can overcome the above problem.As shown in figure 19, sliding mechanism 122 includes three parts：
Gear piece 122A, ratchet 122B and axis tooth 122C.Ratchet 122B and axis tooth 122C are fitted to each other and rotate together.Ratchet 122B peripheries
Multiple ratchets can separably be fitted to each other with multiple teeth groove of gear piece 122A inner circumferentials, so as to fulfill moment of torsion transmission or beat
It is sliding.As Figure 20 is more clearly shown, ratchet 122B includes inner prop D1, connecting pole D2, spine ring D3 and ratchet D4.Ratchet D4 is from spine ring
D3 extends radially outwardly, also, cavity and via multiple connecting pole D2 connections is formed between spine ring D3 and inner prop D1.Inner prop D1
Axis tooth 122C can be connected to via the structure of similar spline.It is located at two phases to the ratchet D4 of the teeth groove in fitted shaft piece 122A
Between adjacent connecting pole D2.In addition, spine ring D3 can be with Inward deflection with elasticity.Therefore, when gear piece 122A passes through ratchet
122B to axis tooth 122C transmit moment of torsion or vice versa axis tooth 122C to gear piece 122A transmit moment of torsion it is excessive when, spine ring D3 can in concave change
Shape so that the teeth groove of the ratchet D4 and gear piece 122A on ratchet 122B skids, so as to achieve the purpose that overload protection.
In the sliding mechanism 122 of the assembling present invention, without being pressed as friction disk type sliding mechanism or being carried out
Pre-assembled, the relevant position that axis tooth 122C, ratchet 122B, gear piece 122B need to be only sequentially placed into housing 150.In addition, especially
Ground, the spine ring D3 of the ratchet 122B of this sliding mechanism 122 is continuous in the circumferential direction around its axis.That is, spine ring
D3 is complete annular section without interruption.Figure 21 schematically shows the stress distribution of this spine ring D3, wherein face
Color, which is more deeply felt, shows that stress is bigger.As it can be seen that ratchet 122B entirety uniform forces, stress concentration phenomenon unobvious.This is substantially better than often
Cantilevered ratchet, the stress concentration of the latter is in the end of cantilever, and the stress value on cantilever is significantly greater than answering for base portion
Force value.Based on improved stress distribution characteristic, intensity higher, the fatigue endurance performance of the ratchet D4 on spine ring D3 of the invention
It is more excellent.Moreover, this split type sliding mechanism 122 is constantly in relaxed state when not working rather than friction plate like that all the time
In deformation state, therefore, as time passage will not produce slipping torque downward trend.
Through experiment test, the slipping torque value of this split type sliding mechanism 122 is up to 7.5kgfcm or so, Neng Gou
Larger breakaway torque is provided in door body rotating mechanism.Therefore, it is allowed to can be arranged in sliding mechanism 122 under power train
Trip.As seen in the embodiment shown in fig. 10, sliding mechanism 122 can be arranged at fourth stage gear, i.e., under separating mechanism 121
Trip.In other embodiments, sliding mechanism 122 can also be arranged on further downstream position.Therefore, by sliding mechanism 122 itself
Manufacture and rigging error caused by the fluctuation of slipping torque will not be significantly enlarged.Thus, output torque at output shaft
Undulating value is obviously reduced.
Magnet steel gear 123 can be set between sliding mechanism 122 and output shaft 13.Magnet steel gear 123 and output shaft 13
On output gear 13A keep engagement.Therefore, magnet steel gear 123 can be rotated synchronously without step-out all the time with output shaft 13.
Therefore, the rotational angle of output shaft 13 can be determined by the rotational angle of detection magnetic steel gear 123, and motor is controlled with this
110 rotation.For example, when detecting that output shaft 13 turns to the first angle that corresponding door body completely closes, or turn to pair
When answering the full opening of second angle of door body, control motor 110 stops operating, and set the rotation direction that it starts next time with
It is last opposite.In order to determine the rotational angle of magnet steel gear 123, magnet steel 123A can be set in magnet steel gear 123, and
And the relevant position outside rotating mechanism sets Hall element.Diverse location of the Hall element based on magnet steel 123A and export
Different voltage signals.Control circuit receives and analyzes the voltage signal and determines turn of magnet steel gear 123 and output shaft 13
Dynamic angle.In a particular embodiment, magnet steel gear 123 is identical with the number of teeth of the gear 13A of output shaft 13, it is ensured that when output shaft 13
After turning over an angle, magnet steel gear 123 turns over equal angular.In this way, it can either avoid near the limited output shaft 13 in space
Position detection structure is set, and is able to ensure that the angular output signal of magnet steel gear 123 is consistent with the rotation situation of output shaft 13,
So as to avoid having differences between feedback signal and actual door body rotational angle.
In addition, in order to meet suitably steering and torque request, at least level-one can also be set in transfer gear train 120
Transition gear, such as 126 He of two-stage transition gear between magnet steel gear 123 and sliding mechanism 122 shown in Figure 10
127, and the transition gear 125 between clutch gear 121A and motor gear 124.It is heavier in view of refrigerator door, and
And output shaft 13 of the barycenter of door body M away from door body rotating mechanism 10, the torque exported it is desirable to output shaft 13 is larger, such as
Up to 3Nm.The gear of conventional plastics one of may not enduringly bear angular torque.For this reason, in certain embodiments,
Need to be made of the multiple gear gears for being arranged close to output terminal using metal.Specifically, the quantity of metal gear can be more than
Two, such as three or four.In the illustrated embodiment, the output shaft 13 of most end three-level, magnet steel gear 123 and transition gear
127 are made of metal.
As shown in figure 22, the upper end of magnet steel gear 123 is provided with magnet steel 123A, magnet steel 123A and magnet steel gear 123
Separated with magnetic steel sleeve 123B.Magnetic steel sleeve 123B adopt it is made of plastic, so as to avoid magnet steel 123A and metal magnet steel gear
123 directly contact and magnetize, so as to avoid the operation of the interference Hall element of magnet steel gear 123.For being engaged to magnet steel gear 123
Transition wheel 127 for, the outboard wheel piece of only transition wheel 127 is made of metal, and its inner side wheel shaft be made of plastics, two
Positioned between person using spline fitted, as shown in the figure.In this way, carrying for cost can be caused using metal material to avoid overall
It is high.
As shown in figure 23, output gear 13A is provided with output shaft 13, it is used for the magnet steel gear 123 for engaging upstream.It is defeated
The bottom of shaft 13 is provided with annular concave-convex spline, for engaging the correspondence keyway on refrigerator door.In addition, during output shaft 13 is
Empty, to allow the inside that cable L passes through output shaft 13 to extend to door body.In actual use, refrigerator door rocks possibility
13 radial direction of output shaft is caused to be rocked, this can cause output shaft 13 to be interfered with the axle bed hole on housing 150 and lid 140.For
This, axle sleeve 13B is set at the upper and lower end parts of output shaft 13, and between output shaft 13 and corresponding axle bed hole.Axle sleeve 13B with
The friction coefficient of 13 material of output shaft is relatively low, available for reducing pivoting friction.Axle sleeve 13B can use lower-cost polyformaldehyde
Material manufactures, and can also use the good needle bearing of rotating property.
The some most preferred embodiments and other embodiment for being used for realization the present invention are described in detail above, but should manage
Solution, the effect of these embodiments is only that citing, and does not lie in and limit the scope of the invention in any way, is applicable in or construct.
Protection scope of the present invention is limited by appended claims and its equivalent way.Those skilled in the art can be in the religion of the present invention
