The specific embodiment
With reference to figure 1-Fig. 5, the described limit-type open out of a kind of specific embodiment of the present invention comprises: open out outside plate 1, open out inner panel 2, flap 3, hinge pivot pin 4, helical spring 5, steel sheet spring 6.
Open out outside plate 1, open out inner panel 2 can adopt identical materials to process, and for example process by steel or other metal or alloy.Open out outside plate 1 is rounded basically on the whole.After open out was installed on the vehicle body, open out outside plate 1 was positioned at the external surface of vehicle body; Open out inner panel 2 is positioned at open out outside plate 1 inboard.Open out outside plate 1 and open out inner panel 2 have constituted the open out lid of limit-type open out together.
Open out outside plate 1 is bonded together with open out inner panel 2, does not have motion each other.Preferably, open out outside plate 1 and open out inner panel 2 are bonded together through bound edge.As shown in the figure, have the bound edge that fastens in the case on the open out outside plate 1, said bound edge coats the edge of open out inner panel 2, thereby makes open out outside plate 1 and open out inner panel 2 be bonded together.
All have pin-and-hole on open out inner panel 2 and the flap 3, therefore, open out inner panel 2 can combine through hinge pivot pin 4 with flap 3, and one common peripheral is around 4 rotations of hinge pivot pin.
The two ends of steel sheet spring 6 are clamped in respectively in the slotted eye of second flange and open out inner panel 2 of flap 3.As shown in the figure, the two ends N of steel sheet spring 6, M are clamped in the slotted eye L place of the second flange K and the open out inner panel 2 of flap 3 respectively.Steel sheet spring 6 is formed by the steel disc of bending, and its generation makes steel disc stretch the elastic force and the moment of torsion of trend.
Preferably, open out inner panel 2 has spacing round platform E, sees Fig. 3 (c).Spacing round platform E is used to limit the opening angle of open out.The height of spacing round platform E can be confirmed according to practical application; Spacing round platform E makes the maximum opening angle of limit-type open out be restricted; In this embodiment; The maximum opening angle that spacing round platform E confirms is 90 degree, also can realize other maximum opening angle through height, the position of adjusting spacing round platform E.
Preferably, the two ends of hinge pivot pin 4 have limiting section, deviate from from pin-and-hole to prevent hinge axis pin 4.In this embodiment, the two ends of hinge pivot pin 4 are crushed, thereby have prevented that hinge pivot pin 4 from deviating from pin-and-hole.
The limit-type open out of this embodiment is instantaneous from being closed to released state, shown in Fig. 3 (a).Steel sheet spring 6 produces first directed force F 1, and helical spring 5 produces second directed force F 2, and these two power F1, F2 produce along two different torque M 1 of direction of the central axis of hinge pivot pin 4, M2 the open out lid.
In the present invention, the rigidity of rigidity, initial angle and steel sheet spring 6 through selecting helical spring 5, the torque M 1 that the torque M 2 that makes second directed force F 2 produce produces greater than first directed force F 1 is so that make open out to automatically spring open.Because the effect of the first flange D is arranged; The helical spring first end A will be limited under this flange; Make the opening movement of open out can stop at crack position, shown in Fig. 3 (b), thereby guarantee that the user has enough fingers to scratch the unlatching that moving space O continues the control open out.The opening angle of said crack position is confirmed according to practical application by rigidity, the initial angle of helical spring 5.
In crack position; When external force continue to affact the open out lid, when making it continue breakdown action the first flange D is to the constraint of helical spring 5 on the open out inner panel 2 owing to have, 5 pairs of open out lids of helical spring (being open out outside plate 1 and open out inner panel 2) do not contact; Therefore; Shown in Fig. 4 (a), the directed force F 2=0 of helical spring 5, open out lid only receive the spring force F1 of steel sheet spring 6.When external force affacts after the open out lid continue to open it and surpass the equilbrium position; The torque M 1 that steel sheet spring 6 is produced is changed into the promotion open out and is moved to the standard-sized sheet direction; This moment, the user can decontrol hand, and steel sheet spring 6 will promote the open out lid to opening the direction motion.Said equilbrium position is the position that active force (the being elastic force) direction of steel sheet spring 6 changes.When the open out lid moves to 90 degree open positions (like Fig. 4 (b)), because the spacing round platform E on the open out inner panel 2 receives stopping of flap 3 planes, the open out lid is limited to this position, and can continue to move to the gusset of bump vehicle body.And the torque M 1 that this moment, steel sheet spring 6 was produced still exists, and can guarantee that the open out lid receives gravity, and external force such as wind-force are done the time spent, still can reliably remain in this open position, make user's refueling operation unaffected.
When limit-type open out work of the present invention, the user is as long as operation is electronic or mechanical type open out latch mechanism is shunk back lock pin, thereby makes limit-type open out release, and open out flicks, and stops at crack position (like Fig. 3 (a)).At this moment; The user can use finger to be inserted in the gap space of open out lid and gusset; Applying opening force makes the open out lid continue to open; After the open out lid was opened above the equilbrium position, the user can let go, and steel sheet spring 6 will promote the open out lid and move to 90 degree open positions (like Fig. 4 (a)).The torque M 1 that this moment, steel sheet spring 6 was produced still exists, and can guarantee that the open out lid receives external force such as gravity, wind-force and does the time spent, still can reliably remain in fully open position, makes user's refueling operation unaffected.
As shown in Figure 5, when needs are closed open out, promote the open out lid and make it cross the equilbrium position, steel sheet spring 6 promotes the open out lid and moves to closing direction, until crack position.In crack position, the user promotes the open out lid once more, makes the open out lid to fastening position, and this moment, the open out lock pin inserted open out inner panel lockhole, made open out get back to lockup state.
Although the present invention describes through above-mentioned preferred implementation, its way of realization is not limited to above-mentioned embodiment.Should be realized that: under the situation that does not break away from purport of the present invention, those skilled in the art can make different variations and modification to the present invention.
