The outside of first cylinder connection end is provided with the first dust cover, is provided with the outside of the first cylinder connection end
Two dust covers.
The first described dust cover is socketed on the first cylinder by interference fit, and the second described dust cover passes through interference
Cooperation is socketed on the second cylinder.
The inner chamber of first cylinder, the inner chamber of the second cylinder are each filled with gas, and the first cylinder inner cavity gas pressure is less than the
Two cylinder inner cavity gas pressures.
Described gas is nitrogen.
The beneficial effects of the invention are as follows：The twin cylinder engine lid supports gas spring, using two cylinder arrangement, one-level cylinder
Play a part of two grades of gas bars simultaneously, two-stage cylinder is using the different inner gas pressure force value of height, the support of course of work two-part
Buffering.Can effectively it solve because the small caused hood gas spring arrangement space of moulding limitation or engine bin space is not enough to
And hood is opened and closed inferior problem, with arrangement space is small, act support stroke is big, operation force value is good and good buffer effect
Advantage.

Embodiment
Enable the above objects, features and advantages of the present invention more obvious understandable, below in conjunction with the accompanying drawings 1~Fig. 3 and tool
The present invention is further detailed explanation for body embodiment.
Embodiment 1：
The twin cylinder engine lid support gas spring that the present embodiment is used, as shown in figure 1, including gas bar 3, band with piston 7
There are the cylinder 1 and cylinder 2 of piston 8.Gas bar 3 is plugged on the inner chamber of cylinder 1 and does piston movement along the inner chamber of cylinder 1, and cylinder 1 is overall to be made
Pull bar for cylinder 2 is plugged in cylinder 2 and does piston movement along the inner chamber of cylinder 2, in the inwall of the connection end of cylinder 1 and in cylinder
Seal is provided with the inwall of 2 connection ends.
Gas spring in the present embodiment uses two cylinder arrangement, and cylinder 1 plays a part of two grades of gas bars simultaneously, in gas spring
In the case that arrangement space is certain, effective support stroke of gas spring is added.Make because cylinder 1 plays gas bar in cylinder 2
With the support stroke of gas spring increases L2 on the basis of l 1, and total support stroke increases to L1+L2.This solves due to
Hood gas spring arrangement space is not enough caused by moulding limitation or engine bin space are small and hood is opened and closed quality
Poor the problem of, have the advantages that arrangement space is small, lift support stroke greatly, operate force value good and good buffer effect.In the present embodiment
Can be according to hood opening angle, to set the length of gas spring.
Embodiment 2：
In the present embodiment, seal is sealing gasket 9 and sealing gasket 10.User can also fill according to the other sealings of actual conditions selection
Put.
The installation ball-and-socket 6 coordinated with the installation ball pin on hood is additionally provided with the free end of cylinder 2, in gas bar 3
Free end be provided with installation ball-and-socket 3 with the cooperation of the installation ball pin of vehicle body.
The outside of the connection end of cylinder 1 is provided with dust cover 4, the outside of the connection end of cylinder 2 is provided with dust cover 5.It is anti-
Dust hood 4 is socketed on cylinder 1 by interference fit, and dust cover 5 is by being interference fitted socket on the cylinder 2.
The inner chamber of cylinder 1 and cylinder 2 is each filled with gas, and the intracavity gas pressure of cylinder 1 should be less than the intracavity gas of cylinder 2
Pressure, described gas is nitrogen.
Cylinder 1 in the present embodiment is from using different inner gas pressure force value F1 and F2 in cylinder 2（F1<F2, specific force value
Set with vehicle operating mode）, for example, pressure is F1=400N, the N of F2=600 in cylinder 1.As shown in Fig. 2 being opened in hood
Process leading portion, due to F1<F2, cylinder 2 first move elongation with respect to cylinder 1, in L2 impulse strokes, two grades of gas springs there is provided compared with
Big power-assisted opening force F2, it is ensured that good unlatching power-assisted effect, in engine starting process back segment, gas bar 3 is transported with respect to cylinder 1
Dynamic elongation can effectively prevent jitter phenomenon when hood is opened into maximum opening there is provided more gentle opening force F1.Such as
Shown in Fig. 3, in hood closing process leading portion, due to F1<F2, gas bar 3 motion compresses, gas bar 3 and gas first in cylinder 1
Support force F1 between cylinder 1 is smaller, it is ensured that soft hood closing forces, in hood closing process back segment, gas bar 3
Motion terminates in cylinder 1, and then the motion compresses in cylinder 2 of cylinder 1, and the support force F2 between cylinder 1 and cylinder 2 is larger,
Effective cushioning effect can be played to the closing velocity of hood, reduces shock sound of the hood to hair cover lock, lifting
The closing quality of hood.
The present invention the opening for car engine cover it can be seen from above-mentioned pair of cylinder supports gas spring embodiment
Feature is closed, the double cylinders of design two-part become force value gas spring structure, with arrangement space is small, flexible stroke is big, operation force value is good
With the advantage of good buffer effect, can effectively solve in the prior art singlecylinderengine lid gas spring in arrangement space and opening and closing product
The problem of in terms of matter.
Although the foregoing describing the embodiment of the present invention, those skilled in the art in the art should manage
Solution, these are merely illustrative of, and can make various changes or modifications to these embodiments, without departing from the principle of the present invention
And essence.The scope of the present invention is only limited by the claims that follow.
