The utility model embodiment provides a kind of extendible hinge, please refers to Fig. 1, Fig. 2 and Fig. 3, and extendible hinge includes:
First base 11, tension spring 12, sleeve 13, telescopic arm 14 and second base 15；First base 11 is used to connect door frame, and
It is hinged with one end of sleeve 13；Tension spring 12 is arranged in sleeve 13, and one end of tension spring 12 is connected with first base 11；It is flexible
14 one end of arm is connect out of the other end of sleeve 13 insertion sleeve 13 with the other end of the tension spring 12 in sleeve 13, is stretched
Arm 14 can be moved relative to sleeve；Second base 15 is used to connect door panel, and hinged with the other end of telescopic arm 14.When
When car door opening, door panel slides backward, and since second base 15 are fixed on door panel, telescopic arm 14 can also be followed
Toward moving back, the tension spring 12 that 14 one end of telescopic arm is ined succession at this time extends door panel, generates the pulling force to door panel, guarantees car door
The steady movement of door-plate.Door panel is toward when return, and tension spring 12 is similarly in tensional state, until door panel returns to pass
Position when closing.
Specifically, one end of above-mentioned telescopic arm 14 is provided with spring card slot 16, the other end of tension spring 12 is fixed on Spring Card
On slot 16.Of course it is to be appreciated that: the fixed form between tension spring 12 and telescopic arm is also not limited to this, riveting and welding
Etc. the purpose that fixed tension spring 12 may be implemented in other connection types.
In some embodiments, extendible hinge further includes sealing ring 17, and sealing ring 17 is made of a kind of elastic material,
Such as: the other end of sleeve 13 is arranged in rubber, sealing ring 17, and the inner ring of sealing ring 17 is close to telescopic arm 14, is used for sealing shroud
Cylinder 13.Sealing ring 17 is constantly in tensional state, therefore persistently can apply pressure to telescopic arm 14, guarantees telescopic arm 14 and sealing
There is no gap between circle 17, to achieve the effect that dust-proof.In addition, telescopic arm 14 is when moving reciprocatingly, sealing ring 17 can be after
It is continuous to stretch, telescopic arm 14 will not be hindered.Wherein, sealing ring 17 is y-type seal ring.Y-type seal ring is reliable with sealing performance, rubs
Wiping resistance is small, movement is steady, resistance to pressure is good and advantages of simple structure and simple, and is widely used in moving back and forth.Certainly, other
In embodiment, sealing ring 17 is also possible to other sealing devices for playing identical sealing effect, does not repeat further herein.
In some embodiments, extendible hinge further includes linear bearing 18, and linear bearing 18 is arranged in sleeve, is located at
The inner hole of the other end of sleeve 13, linear bearing 18 is contacted with telescopic arm 14.When telescopic arm 14 move back and forth when, telescopic arm 14 with
It is point contact between linear bearing 18, is rolling friction, so the abrasion very little of telescopic arm 14.

Fixed form between sleeve 13 is not limited only to this, is also possible to other fixed forms such as pin connection.
Telescopic arm 14 is detached from sleeve 13 in order to prevent, and one end of telescopic arm 14 is provided with flange 19, flange 19 can with it is straight
Spool holds 18 abuttings.When accident occurs, when telescopic arm 14 will be drawn out sleeve 13, the flange 19 of 14 end of telescopic arm can be by straight line
Bearing 18 blocks, and telescopic arm 14 is prevented to be drawn out.It is also possible to which it is too long to prevent tension spring 12 to be stretched, plastic deformation is generated.
In order to improve the wearability of telescopic arm 14, the outer surface of telescopic arm 14 is provided with MC nylon layer.MC nylon has certainly
The characteristics of lubrication, can reduce the flexible resistance of telescopic arm 15.
Specifically, above-mentioned telescopic arm 14 is alloyed copper.Alloyed copper has the characteristics that high intensity, can prevent telescopic arm 14 from producing
Raw bending deformation or fracture.Certainly, in other embodiments, telescopic arm 14 can also be by other material groups with same characteristic features
At not repeating further herein.
In the utility model embodiment, door panel will drive the movement of telescopic arm 15 when moving back, to stretch tension spring
12, to make door panel that can prevent so persistently by the pulling force from tension spring 12 in the direction perpendicular to its own
Double swerve in door panel slipping realizes the steady switch of car door.In addition, the setting of linear bearing 17 can be reduced
Friction when telescopic arm 15 is mobile, improves the wearability of the utility model.
The utility model additionally provides a kind of car door, including a kind of extendible hinge, door panel and door frame.It is described
One end of extendible hinge is connected with door panel, and the other end of the extendible hinge is connected with door frame.It is described to stretch
Contracting hinge is consistent with the structure and function of the extendible hinge in above-described embodiment, for the structure and function of extendible hinge
Above-described embodiment can be referred to, is no longer repeated one by one herein.
The utility model additionally provides a kind of vehicle, including a kind of car door.Car door in the car door and above-described embodiment
Structure and function it is consistent, above-described embodiment is seen for the structure and function of car door, is no longer repeated one by one herein.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
