There is first annular groove 521, the first rubber ring 54 is sheathed in first annular groove 521.Referring to Figure 10,53 outer wall of drive shaft is set
It is equipped with second annular groove 531, the second rubber ring 55 is sheathed in second annular groove 531.It stretches position in Figure 10 shown in C
Enter in the second mounting hole 512 in Fig. 8, in the present embodiment, this part-structure is riveted on connecting plate 51.
In other embodiments, above-mentioned first rubber ring 54 can also be at least two, two neighboring first rubber ring 54
Between be spaced setting, the axial distance between two neighboring first rubber ring 54 along door-hinge 52 can be identical, also being capable of not phase
Together, specific spacing distance is determine according to actual needs.
The quantity and set-up mode of second rubber ring 55 are similar with the set-up mode of the first rubber ring 54.
In other embodiments, can also only the first rubber ring 54 be installed on door-hinge 52 or only installed in drive shaft 53
Second rubber ring 55.
After door-hinge 52 is inserted into rotary shaft hole, door-hinge 52 is not contacted with the inner wall of rotary shaft hole, and the first rubber ring 54 is located at door
Between axis 52 and rotary shaft hole wall.After installation, the first rubber ring 54 is in extrusion deformation state.Similarly, the second rubber ring 55
Between drive shaft 53 and installation hole wall, after drive shaft 53 is inserted into mounting hole, the second rubber ring 55 is in extrusion deformation state.
Door-hinge 52 and door component 32 is set to keep relative static conditions by the first rubber ring 54, the second rubber ring 55 makes drive shaft 53 and door
Component 32 keeps relative static conditions.Meanwhile because there are foozle and door-hinge 52 and drive shafts 53 itself for refrigerator doors itself
The factors such as the installation error of foozle and all parts, lead to automatic opening and closing door module 2 after mounting, and appearance can not be suitable
Refrigerator door open-close door has some setbacks after benefit installation or installation.Therefore, it is solved by the first rubber ring 54 of setting and the second rubber ring 55
Scale error and rigging error caused by door component and refrigerator main body assemble, keep assembly more time saving and energy saving.Meanwhile rubber is set
Circle plays good buffer function when door component 32 rotates.
In the present embodiment refrigerator doors automatic switch Hinge by be arranged on door-hinge 52 first rubber ring 54 and/or
The second rubber ring 55 is arranged in drive shaft 53.By the way that the first rubber ring 54 is arranged, after rotary shaft is inserted into rotary shaft hole, by the
One rubber ring 54 makes up the scale error generated in rotary shaft hole manufacture or assembling process or Form and position error.Similarly, it is arranged second
Rubber ring 55 makes up the scale error or Form and position error of mounting hole.It is missed by scale error or morpheme of the setting rubber ring to refrigerator
The fault-tolerance of difference increases.Under the action of being automatically switched module, when driving refrigerator doors open or close, switch is more smooth, stablizes,
It is not in catching phenomenon.
A kind of refrigerator is additionally provided in the present embodiment, is automatically switched Hinge including above-mentioned refrigerator doors.The refrigerator is adopted
