Abstract

The invention discloses a circlip type refill opening door. The door comprises a door panel and a hinge panel, wherein the door panel and the hinge panel are in rotary connection through a hinge shaft; the hinge shaft is fixed on the door panel, and comprises a bent part; one end of a circlip is connected with the hinge panel, while the other end of the circlip is hinged on the bent part. The door can automatically open or close by applying certain acting force on the refill opening door through the design of the door panel, the hinge shaft, the hinge panel and the circlip, therefore, the operation is very convenient. The circlip generates pretightening force during installing, so the refill opening door is ensured to be closed tightly without refilling oil. Furthermore, a bump is arranged under the circlip on the door panel correspondingly, so the opening angle of the refill opening door can be controlled.

Description

Circlip type refill opening gate

Technical field

The invention belongs to vehicle body and exterior trim, relate in particular to a kind of Circlip type refill opening gate.

Background technology

The effect that oil filler wicket on the automobile has the protection oil pipe and beautifies.Except car door, the wicket that utilization rate is quite high.The defectives such as domestic present oil filler wicket design all is simple chain connection, and existence is not closed completely, opening angle is wayward.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of oil filler wicket of circlip type, not only applies certain effect power and just can make wicket elasticity open or shut, and guarantee that wicket keeps closing state under normal conditions, to overcome deficiency of the prior art.

The present invention is by the following technical solutions:

A kind of Circlip type refill opening gate comprises door-plate, flap, and door-plate, flap connect by hinge axis, and described hinge axis is fixed on the door-plate, and comprises a bend, and jump ring one end is connected with flap, and the other end is articulated on the bend.

The present invention has set up jump ring between hinge axis and flap, hinge axis is fixed on the door-plate, and door-plate rotates, and hinge axis and then rotates, and jump ring is articulated in the bend of hinge axis and is relatively movable.The clamp spring wound bend rotates, rather than hinge axis.In wicket switching process, jump ring stretches and produces change in torque.So just can realize the opening and closing of wicket circlip type.

Further, hinge axis also has another bend, and two bends stagger on Different Plane, and bend is affixed on the door-plate inboard, and fixes by fastener.Realize the fixing of hinge axis and door-plate by this bend.

Preferably, have draw-in groove on the described flap, be connected with jump ring one end.On the pivot joint of jump ring one end and the bend, the other end inserts in the draw-in groove, and the crooked compression of jump ring produces pretightning force thus.

Further, also be provided with prominent bag on door-plate, the position of this prominent bag is corresponding to an end of jump ring connecting bending pars convoluta.When wicket was opened to certain angle, prominent bag was run into jump ring and is interfered, and has controlled thus the opening angle of wicket.

Preferably, also be covered with outside plate in the door-plate outside.

The present invention as long as apply certain active force to the oil filler wicket, just can make wicket automatically open or close by the design of end of door plate, hinge axis, flap, jump ring, and operation is very convenient.Because when mounted, make jump ring produce pretightning force, can guarantee that the oil filler wicket closes in oilless situation.In addition, on door-plate, the prominent bag of correspondingly establishing below jump ring can be controlled the opening angle of oil filler wicket.

Fig. 1 is structural representation of the present invention.

Fig. 2 is exploded view of the present invention.

Fig. 3 is forward view of the present invention.

The specific embodiment

Such as Fig. 1, Fig. 2, Circlip type refill opening gate mainly comprises outside plate 1, door-plate 2, hinge axis 3, flap 4, jump ring 5.Door-plate 2 is embedded in the outside plate 1 and is fixed, and door-plate 2 is provided with fixed bearing 21, and this bearing 21 passes through hinge axis 3 chain connections with flap 4.In the present embodiment, hinge axis 3 is bent axle, and two

bends

31,32 are arranged, and these two

bends

31,32 stagger, and on same plane, does not see Fig. 3.Jump ring 5 is located on the hinge axis 3, has draw-in groove 41 on the flap 4, and jump ring 5 one ends and hinge axis 3 are pivotally connected, see Fig. 1, and the other end snaps in the draw-in groove 41.In the present embodiment, jump ring 5 one ends are hook-shaped, ride on the hinge axis 3, and other end sectional dimension is less, jump ring 5 is bent to certain radian after, can insert jump ring 5 in the draw-in grooves 41.In wicket switching process, go for a stroll pars convoluta 31 of jump ring 5 rotates.On door-plate 2, establish respectively prominent bag 22 and projection 23.Prominent bag 22 is positioned at the below of jump ring 5, in the wicket rotation process, dashes forward and wraps 22 bottoms 51 that can run into jump ring 5 specifically; Also be provided with fastener 24 on the projection 23, bend 32 is embedded on the projection 23, is that bend 32 is flattened on the door-plate 2 specifically, encases bend 32 by fastener 24 bendings, then hinge axis 3 is fixed on the door-plate 2.When wicket rotated, hinge axis 3 was followed together and is rotated, and bend 31 relative flap 4 motions cause jump ring 5 compressions or elongation.When wicket forwards certain angle to, the bottom 51 of jump ring 5 can contact with prominent bag 22 (bottom 51 is S-shaped, and first half garden arc is enclosed within on the bend 31, and the arc ledge of second half garden arc is run into prominent bag 22), produce and interfere, determine thus the opening angle of wicket.Therefore, the position of prominent bag 22 and highly have designed.Open the geomery of Position Design, jump ring 5 of draw-in groove 41 and material therefor on the flap 4 all relevant with the pretightning force that produces after jump ring 5 assemblings, pretightning force is larger, and the unlatching arm strength is also larger.

When the oil filler wicket was installed, flap 4 one ends were connected with door-plate 2, and the other end then is fixedly connected with vehicle body.

Operating principle of the present invention is as follows: jump ring 5 bends to a radian and is pressed into 41 li of draw-in grooves during original state, produces pretightning force, and under nature, the oil filler wicket is normally off like this.During unlatching, wicket pulls open, and hinge axis 3 and then together rotates, bend 31 relative flap 4 motions, and jump ring 5 continues compression (this moment, jump ring 5 stressing conditions changed).When wicket was opened to a certain position, jump ring 5 torque directions were just in time by center of rotation (hinge axis 3), and torque this moment is 0, and this moment, the position was called the critical point position.Crossed critical point, torque produces, and direction and reverse before, does not need thrust, and hinge axis 3 is rotated further, and wicket is opened fully, until prominent bag 22 is run into till the bottom 51 of jump ring 5.

Closing process is similar with unlatching.

Wicket is closed, and hinge axis 3 and then together rotates, bend 31 relative flap 4 motions, and this moment, jump ring 5 stressing conditions changed.When wicket closes a certain position (that critical point position of namely opening), jump ring 5 torque directions are just in time by center of rotation (hinge axis 3), and torque this moment is 0.Crossed critical point, torque produces, and direction and reverse before, does not need thrust, hinge axis 3 is rotated further, until wicket is shut.

The present invention as long as apply certain active force to the oil filler wicket, just can make wicket automatically open or close by the design of end of door plate 2, hinge axis 3, flap 4, jump ring 5, and operation is very convenient.Because when mounted, make jump ring 5 produce pretightning force, can guarantee that the oil filler wicket closes in oilless situation.In addition, on door-plate 2, the prominent bag 22 of correspondingly establishing below jump ring 5 can be controlled the opening angle of oil filler wicket, has crossed after critical point opens automatically when wicket, and jump ring 5 distortion cause interference until run into prominent bag 22, and opening process finishes.Therefore, the height of this prominent bag 22 can determine opening angle.
