Embodiment
Below in conjunction with specific embodiments and accompanying drawing, the utility model is further described in detail.It is intended to elaborate specific embodiments of the present utility model, does not produce any restriction to the utility model, and protection domain of the present utility model is as the criterion with claims.
With reference to Fig. 1, 2, show a kind of hydraulic damper for engine compartment cover, comprise an oil hydraulic cylinder 1, described oil hydraulic cylinder 1 main body is cylindrical tube 2, described cylindrical tube about 2 is connected to the first disk 3 and the second disk 4, hydraulic oil (not shown) is perfused with in described oil hydraulic cylinder 1, the second disk 4 in described oil hydraulic cylinder 1 is fixed with one end of the first spring 5, described first spring 5 the other end is connected with large piston 6, one small piston 7 is positioned at described large piston 6 described first spring 5 part dorsad, one end of metallic rod 8 is fixed with in the middle of the one side of described small piston 6 described large piston 7 dorsad, described metallic rod 8 the other end runs through described first disk 3 and is connected with tinsel 9, described oil hydraulic cylinder 1 is fixedly connected with vehicle body sheet metal (not shown), described tinsel 9 is connected with described engine compartment cover (not shown) is separable.
In a preferred embodiment, between described metallic rod 8 and described first disk 3, described metallic rod 8 is provided with seal ring 10, prevents the seepage of hydraulic oil.The first disk 3 outside described oil hydraulic cylinder 1 is fixed with the second spring 11 around described metallic rod 8.Described cylindrical tube 2 is provided with cylindrical thread (not shown), described vehicle body sheet metal is provided with circular hole (not shown), the toroidal surface of described circular hole is provided with circular hole screw thread (not shown), described oil hydraulic cylinder 1 is spirally connected by cylindrical thread, circular hole screw thread with described vehicle body sheet metal, those of ordinary skill in the art are clear, connection between oil hydraulic cylinder and vehicle body sheet metal, can also be connected together, rivet, related domain customary means such as bonding, should as limit.The one side fluidisation of described tinsel 9 described metallic rod 8 dorsad has rubber sheet gasket 12, sends larger noise when preventing engine compartment cover from closing.Described large piston 6 is cylindrical, the diameter of described large piston 6 is identical with described cylindrical tube 2 inwall body diameter, described large piston 6 runs through and is provided with multiple oil through 13, described small piston 7 is cylindrical, and the diameter of described small piston 7 is less than described cylindrical tube 2 inwall body diameter.
When use of the present utility model for the hydraulic damper of engine compartment cover after, in the process killing engine hatchcover (not shown), engine compartment cover contact rubber tinsel 9 promotes metallic rod 8 and small piston 7 compresses downwards, hydraulic oil is slowly pressed into above small piston 7 from small piston 7 and the gap of oil hydraulic cylinder 1 inwall, plays the effect of buffering.When small piston 7 continues descending, when engine compartment cover is locked into into latch hook (not shown), small piston 7 is the large piston 6 of contact just, owing to there is the effect of the first spring 5 holding power of the damping of large piston 6 and below thereof, can reduce prevent too quickly closedown hatchcover the gap value reserved.When vehicle high-speed operation, engine compartment cover shake, the first spring 5 and hydraulic oil coordinate the movement travel reducing engine compartment cover, reduce noise, and can reduce the gap value reserved between engine compartment cover and vehicle body sheet metal.Preferably, the one side fluidisation of described tinsel 9 described metallic rod 8 dorsad has rubber sheet gasket 12, sends larger noise when preventing engine compartment cover from closing.
Preferably, when vehicle high-speed operation, engine compartment cover shake, hydraulic oil passes through from the oil through 13 large piston 6, makes its amplitude weak rapidly, due to the buffer function of the first spring 5, second spring 11 and large piston 6, small piston 7, cause amplitude less and not easily send noise.So can reduce gap when design in early stage, while making vehicle modeling more attractive in appearance, noise also can reduce greatly.Really the purpose of this utility model is reached.
Above-described embodiment is only for illustration of the utility model; and be not to restriction of the present utility model; the those of ordinary skill of relevant technical field; when not departing from the utility model scope; various change and modification can also be made; therefore all equivalent technological schemes also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
