Detailed description of the invention
Below in conjunction with drawings and embodiments, the utility model is described in further detail;
See Fig. 1, Fig. 5, Fig. 6 and Fig. 7, the utility model is the same with the automobile engine nacelle forward end seal structure of prior art, comprise bonnet 1, sealing band 3 that front bumper decoration bright wisp 2, elastomeric material are made and plastic clamp 4, described sealing band 3 comprises mount pad 32, sealing band 3 is decorated between bright wisp 2 at bonnet 1 and front bumper, and it is fixing that its mount pad 32 adopts plastic clamp 4 and the lower surface of bonnet 1 to fit.From Fig. 4, Fig. 5 and Fig. 6, the automobile engine nacelle forward end seal structure difference of the utility model and prior art is; Sealing band 3 of the present utility model also comprises and to be stretched out downwards by the front end of its mount pad 32 and bottom is flexibly pressed in the sealing lip limit 31 on the surface of front bumper decoration bright wisp 2, aligns with the front end of bonnet 1 in the front end of the mount pad 32 of sealing band 3.So, this part lower surface between the front end of bonnet 1 and sealing band 3 is just blocked by sealing band 3, has sealed.This part lower surface would not pile up the pollutants such as rainwater and dust again, and in the process opening bonnet 1, the pollutantss such as the rainwater also just do not piled up and dust enter in machinery space, have polluted.Thus, leak tightness of the present utility model is better.In addition, sealing lip limit 31 entirety of sealing band 3 of the present utility model is strip shape, and steep 35 overall for compared with bar shaped cylindrical cavity body with the sealing of the sealing band 3 of prior art, shape and structure is fairly simple.Thus, the entirety manufacture ratio of sealing band 3 is easier to.
The sealing lip limit 31 of described sealing band 3 is made up of lower density EPDM gelatin sponge, and mount pad 32 is made up of hard EPDM sponge.This makes the sealing lip limit 31 of sealing band 3 and the elasticity of mount pad 32 and hardness all better, and can meet sealing needs.
The lower density EPDM gelatin sponge that the sealing lip limit 31 of described sealing band 3 is 0.65 ± 0.15g/cm3 by density is made, and mount pad 32 is made up of the hard EPDM sponge of hardness more than HA70 °.This makes the sealing lip limit 31 of sealing band 3 and the elasticity of mount pad 32 and hardness all better, and can meet sealing needs better.
From Fig. 5, Fig. 6 and Fig. 7, the mount pad 32 of described sealing band 3 is provided with at least two mounting holes 34, described bonnet 1 also comprises bonnet inner panel 12, and described bonnet inner panel 12 is provided with the cooperation mounting hole 13 corresponding with the mounting hole 34 on mount pad 32; Described plastic clamp 4 comprises neck 40 and diameter and is greater than the diameter of this neck 40 and is connected to the dop 41 of the lower end of neck 40, and diameter is greater than the diameter of described neck 40 and is connected to the clamping tooth 42 of the upper end of neck 40, the quantity of the cooperation mounting hole 13 on the bonnet inner panel 12 of the quantity of plastic clamp 4 and the mounting hole 34 on the mount pad 32 of sealing band 3 and bonnet 1 is corresponding, the mount pad 32 of described sealing band 3 is by mounting hole 34 and coordinate mounting hole 13, adopts plastic clamp 4 and the lower surface of the bonnet inner panel 12 of bonnet 2 to fit fixing.This make sealing band 3 and bonnet 1 be fixedly connected with more convenient easily and the reliable and replacing of sealing band 3, keep in repair also more convenient.
Mounting hole 34 on the mount pad 32 of described sealing band 3 and the cooperation mounting hole 13 on bonnet inner panel 12 respectively have 14, and correspondingly, described plastic clamp 4 also has 14.This makes sealing band 3 more reliable with being fixedly connected with of bonnet 1.
From Fig. 5, Fig. 6 and Fig. 7, the dop 41 of described plastic clamp 4 is that disc, clamping tooth 42 are for mushroom-shaped.When this makes plastic clamp 4 to be fit into fixing seal bar 3 in the mounting hole 34 on the mount pad 32 of sealing band 3 and the cooperation mounting hole 13 on bonnet 1, grip with assembling all easily more convenient, and fixing more reliable.
As seen from Figure 6, the mount pad 32 of described sealing band 3 is provided with the positioning bar 33 raised up, the side that the mount pad 32 that described positioning bar 33 is arranged on sealing band 3 is fitted with bonnet 1, and overlaps with the line of centers of all mounting holes 34 on mount pad 32.The Working position of all mounting holes 34 on mount pad 32 can be enable like this with positioning bar 33 for benchmark, process more convenient.
As seen from Figure 6, the shape of positioning bar 33 that the sealing band mount pad 32 of described sealing band 3 is provided with is triangular form.This make positioning bar 33 relatively simple for structure, manufacture than being easier to.
As seen from Figure 4, the sealing lip limit 31 of described sealing band 3 is tiltedly stretched out from the front end of its mount pad 32 downwardly towards hypsokinesis and its bottom is provided with guiding part 310 from backward upper turnup.When this closes after making bonnet 1 to open again, the sealing lip limit 31 of sealing band 3 is merely able to stretch out downwards backward and the bottom on sealing lip limit 31 will flexibly be pressed on the surface to the rear of front bumper decoration bright wisp 2, guarantee that the ground, front end that the sealing lip limit 31 of sealing band 3 can not overturn forward, bottom does not exceed bonnet 1 is flexibly pressed on the surface to the front of bumper/spoiler decoration bright wisp 2, and then guarantee not occur gap between the both sides that bonnet 1 and front bumper decorate bright wisp 2, ensure good sealing effectiveness.
