3.The hinge transmission component 3 is equipped with keeps hinge seat 2 past fixed by fixed point rotary folding of the hinge joint hinged with fixed seat 1
1 direction of seat converts into and is inlaid in the drive connection group 4 in fixed seat 1.The front end of drive connection group 4 is hinged on fixed seat 1, passes
The rear end of dynamic connection group 4 is hinged on hinge seat 2.
That is, when refrigerator is closed, hinge transmission component 3, drive connection group 4 are respectively with the hinge joint hinged with fixed seat 1
Fixed point is folded, and the arm of force that elongated hinge seat 2 rotates reduces the thrust for pushing refrigerator door, is conveniently operated.Moreover, working as ice
Chamber door body close after, hinge seat 2 can using the hinge joint hinged with fixed seat 1 be fixed point rotary and convert into be inlaid in fixed seat 1,
The gap of the component of hinge inner is reduced, assembly volume is reduced, avoids the accumulations such as steam, dirt.
Shown in referring to Fig.1, the drive connection group 4 includes transmission strut 41, transmission swing rod 42.It is driven the front end of strut 41
It is hinged on fixed seat 1, the both sides for being driven the rear end of strut 41 are hinged with the front of transmission swing rod 42 respectively, after being driven swing rod 42
End is respectively hinged at fixed seat 1.
When refrigerator door is opened, hinge seat 2 is opened outward, and drive transmission arm 31, transmission strut 41 respectively with
The hinged hinge joint of fixed seat 1 is that fixed point rotates outward, when transmission arm 31, transmission strut 41 rotate to designated position, transmission
Connecting rod 32 is respectively that fixed point rotates outward with the hinge joint with transmission arm 31, transmission strut 41 with transmission swing rod 42, at this point, transmission
Swing rod 42 and the hinge joint of transmission strut 41, the hinge joint, hinge seat 2 and kinematic link 32 of transmission swing rod 42 and hinge seat 2
Hinge joint, kinematic link 32 and the hinge joint of transmission arm 31 form four side balance exercises.The arm of force that elongated hinge seat 2 rotates, subtracts
The thrust for pushing refrigerator door less, is conveniently operated.
Wherein, the outside of the transmission swing rod 42 connects block 45 equipped with the limitation of 2 open position of limitation hinge seat, and limitation connects
Block is connect to be in 41 outside of transmission strut and be connected on transmission swing rod 42.When kinematic link 32 and transmission swing rod 42 revolve respectively
When going to nominal position, even block 45 heads on transmission strut 41 for limitation, and transmission swing rod 42, kinematic link 32, hinge seat 2 is made to locate respectively
In double leval jib supporting rack, hinge seat 2 is made to be fully opened, reinforce support strength, improved operation smoothness and stability, reduction are made an uproar
Sound.
In addition, the front of the transmission swing rod 42 is equipped with and is rotated with the hinge hinged with transmission strut 41 and convert into and be connected to
The connection convex edge 43 of hinge seat 2, connection convex edge 43 are equipped with the inclined surface 44 contacted with 2 face of hinge seat.It is closed in refrigerator door
When, hinge seat 2 is converted into inside, and push kinematic link 32 with transmission swing rod 42 respectively with transmission arm 31, transmission strut 41
Hinge joint be fixed point rotate inside, kinematic link 32 with transmission swing rod 42 rotate to designated position when, kinematic link 32 with pass
Dynamic strut 41 is folded in transmission arm 31 and is driven on strut 41, and the inclined surface 44 for connecting convex edge 43 is contacted with 2 face of hinge seat.
Then, the continuation of hinge seat 2 elapses inside, and drive transmission arm 31, transmission strut 41 are respectively with the hinge joint hinged with fixed seat 1
Fixed point rotates inside, so that transmission arm 31, transmission strut 41 are inlaid in respectively in fixed seat 1, to realize that hinge seat 2 is inlaid in
In fixed seat 1, the gap of the component of hinge inner is reduced, assembly volume is reduced, avoids the accumulations such as steam, dirt.
Shown in referring to Figure 1 to Figure 7, the hinge transmission component 3 is equipped with applies the effect of snubber elastomeric pressure to hinge seat 2
Elastic buffering mechanism 5.The interconnection of elastic buffering mechanism 5 has when rotated to the application of elastic buffering mechanism 5 and snubber elastomeric
Pressure balanced pressure on top surface and the buffer head 6 that arbitrarily stops, end and the drive connection group 4 of buffer head 6 when hinge seat 2 being made to open
It is hinged.The fixing end of the elastic buffering mechanism 5 is fixed on transmission arm 31, and the elastic tip of elastic buffering mechanism 5 is slidably connected
It is connect on transmission arm 31 and with buffer head 6,6 axis connection of buffer head is on the hinge joint of transmission arm 31 and kinematic link 32.
That is, elastic buffering mechanism 5 is made to apply snubber elastomeric pressure to buffer head 6, buffer head 6 is then slow to elasticity when rotated
Flushing device 5 applies and the pressure balanced pressure on top surface of snubber elastomeric, stable, uniform force, and can reach refrigerator door opening
The purpose that Shi Renyi is stopped, using flexible, strong applicability ensure the using effect of hinge, it is ensured that the use quality of refrigerator.
In practical applications, the elastic buffering mechanism 5 includes spring lever 51, spring part 52.The fixing end of spring lever 51
It is fixed on the transmission arm 31 of hinge transmission component 3, the movable end of the spring lever 51 is equipped with push rod 53.Push rod 53 is flexible to be connected
It is connected on the movable end of spring lever 51, and 53 axis connection of the push rod has the idler wheel 54 being connected with each other with buffer head 6, the spring
Part 52 is sleeved on front end and the push rod 53 that on spring lever 51 and both ends difference top pressure spring lever 51.Wherein, spring part 52 is spiral
Spring.When hinge is run, 52 one end of spring part acts on transmission arm 31, and 52 other end of spring part acts on idler wheel by push rod 53
54 opposite transmission arm 31 elastic reset slidings.Concrete structure is：The transmission arm 31 is equipped with sliding groove 33, and the push rod 53 is installed
There are the sliding axle 55 for the installation that matches with idler wheel 54, sliding axle 55 to be slidably connected on sliding groove 33.Reinforce operation stability with it is suitable
Smooth property improves the use quality of elastic buffering mechanism 5.Period, idler wheel 54 freely roll；To avoid spring part 52 from acting directly on
On idler wheel 54, the action of idler wheel 54 is influenced, for this purpose, 53 telescopic action of push rod on sliding axle 55, ensures that elastic buffering mechanism 5 is normal
It uses.
In addition, the buffer head 6 is equipped with the connecting shaft 61 with 32 axis connection of kinematic link, buffer head 6 is with connection
Axis 61 is fixed point rotary and the eccentric buffering wheel that is connect with 54 face of idler wheel.Since eccentric buffering wheel has eccentric smooth arc
Face generates squeezing action with idler wheel 54, and idler wheel 54 rolls on the arcwall face of eccentric buffering wheel, and rotation is opened to reach hinge
Buffering effect is generated when turning, and is reduced the friction between component, is kept buffering more smooth, muting function is notable.
Above-mentioned specific embodiment is only the preferable specific implementation mode of effect of the present invention, all and of the invention built-in refrigerators
The identical or equivalent structure of buffer hinge, is within the scope of the invention.
