Further, more easily be installed on engine case to make the shock absorber of this engine case, at least one in buffer cell and pilot unit is provided with cavity, or buffer cell is provided with cavity namely, pilot unit is provided with cavity, or buffer cell and pilot unit are provided with cavity simultaneously.Preferably, buffer cell and pilot unit can be provided with cavity simultaneously.Like this, the shock absorber of this engine case is easily deformable under external force, more easy and convenient when workman installs.
As shown in Figure 3, the two ends of the shock absorber of engine case all can be provided with annular groove 301.In Fig. 3,101 is buffer cell, 102 for clamping unit and 103 be pilot unit.
Preferably, each unit of the shock absorber of engine case all can be made up of EP rubbers, and EP rubbers has and better rushes elastic force.The bottom-to-top-height of the shock absorber of engine case is 14 millimeters, and total weight is 2 grams.
The shock absorber of this engine case can effectively prevent car engine cover from producing vibration and abnormal sound, the particularly vibration of engine case Z-direction (i.e. vertical direction), the risk of pounding front bumper or grid when engine case closes suddenly can be reduced, turn reduce the potential safety hazard of running car.The structure of the shock absorber of this engine case is simple, small volume; Weight is little, contributes to automobile loss of weight; Cheap, be conducive to automobile and reduce costs.
In sum, the shock absorber of the engine case that the embodiment of the present invention provides, in vehicle traveling process can by buffer cell effectively stop engine case due to vibration downward overexercise, reduce the amplitude of engine case vibration, thus buffer action played to engine case.Compared to existing shock absorber, reduce the volume and weight of shock absorber, make the structure of engine case more simple, and reduce the cost of shock absorber.
Embodiments provide a kind of engine case, comprise the shock absorber of the engine case shown in Fig. 1 or Fig. 2.Concrete, as shown in Figure 4, this engine case 40 is made up of the shock absorber 10 of engine case outside plate 401, engine case inner panel 402, engine case brace panel 403, front bumper 405, grid 406 and engine case.
Preferably, as shown in Figure 5, this engine case 40 can be furnished with the shock absorber 10 of shock absorber 10,2 unadjustable engine cases of 4 adjustable engine lids.
Wherein, the shock absorber 10 of 2 throttleable motor lids is arranged between engine case and water tank upper beam 409, the shock absorber 10 of other 2 throttleable motor lids is arranged in engine case and headlight is installed between crossbeam 408, by regulating the shock absorber 10 of 4 throttleable motor lids at engine case inner panel and water tank upper beam 409, the height that headlight is installed between crossbeam 408 adjusts engine case and the Pingdu with all edge pieces, as: the Pingdu between engine case and fender guard, Pingdu between engine case and head light, and the Pingdu etc. between engine case and front bumper.
As shown in Figure 4, the shock absorber 10 of 2 unadjustable engine cases is arranged between engine case inner panel 402 and grid 406, the shock absorber 10 of these 2 unadjustable engine cases is about overall height and face, vehicle commander place symmetry, and the centerline parallel of the shock absorber 10 of each unadjustable engine case is in overall height and face, vehicle commander place.When engine case is closed, the shock absorber bearing surface of the unadjustable engine case of grid is vertical around the tangential direction of hinge for engine hood rotary motion camber line with the shock absorber 10 of unadjustable engine case.The shock absorber 10 of unadjustable engine case is arranged on engine case inner panel, and the diameter of mounting hole is 9 millimeters, and middle part clamping unit card is in stamping holes.When engine case is closed, as shown in Figure 4,10.5 millimeters, gap between engine case inner panel 402 and grid 406, the height of the lower buffer unit of the shock absorber 10 of unadjustable engine case is 9 millimeters, static clearance between the shock absorber 10 of unadjustable engine case and grid 406 is 1.5 millimeters, gap is left, mainly in order to avoid impact that the adjustment of the gap between engine case and grid 406 and Pingdu brings between the shock absorber 10 of unadjustable engine case and grid 406.Because, on the one hand, if the shock absorber 10 of unadjustable engine case and grid 406 directly contact when static state or have amount of interference, when regulating gap, the Pingdu of engine case and grid 406, the height of shock absorber 10 between engine case inner panel and water tank upper beam 409 (as shown in Figure 5) of throttleable motor lid can be affected, cause gap, Pingdu do not meet the demands; On the other hand, in vehicle traveling process, as shown in Figure 4, if the shock absorber 10 of unadjustable engine case and grid 406 Long contact time, grid 406 may be caused to ftracture, and front bumper 405 sinks.Finally, when killing engine lid, shock absorber 10 and the grid 406 of unadjustable engine case have the contact of moment, during contact, because the elasticity of the shock absorber 10 of unadjustable engine case itself can stop the downward overexercise of engine case, thus avoid engine case and headlight, the interference between engine case and front bumper; Also reduce the amplitude that vehicle vibrates through limit road surface engine case Z-direction simultaneously, prevent engine case because Oscillation Amplitude is excessive and all edge pieces are interfered and produced abnormal sound.
It should be noted that, the shock absorber of the engine case that the embodiment of the present invention provides is applicable to various, some vehicles because of bump rubber arrange unreasonable, automobile is through limit road surface, engine case vibration, abnormal sound can be there is, and this invention can effective head it off, specifically can different according to engine case inner panel and internal clearance between grid or front bumper, the height of the buffer cell of the shock absorber of appropriate change engine case, and when ensureing static, between the shock absorber of engine case and lower support face, retain the gap of 1-2 millimeter.
In sum, the engine case that the embodiment of the present invention provides, in vehicle traveling process can by the shock absorber be arranged in engine case effectively stop engine case due to vibration downward overexercise, reduce the amplitude of engine case vibration, thus buffer action played to engine case.This shock absorber, compared to existing shock absorber, reduces the volume and weight of shock absorber, makes the structure of engine case more simple, and reduces the cost of engine case.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
