Detailed description of the invention

Below in conjunction with embodiment, the utility model is described in detail.The identical Reference numeral of wherein identical parts represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric centre respectively.

The structural representation of the damper element that Fig. 4 provides for the utility model embodiment, the structural representation of foam block in the damper element that Fig. 5 provides for the utility model embodiment.As shown in Figure 4 and Figure 5, the utility model embodiment provides a kind of damper element 1, comprises body 11 and foam block 12.

Described body 11 comprises for the location division 111 fixing with vehicle body and buffer part 112, and described location division 111 is inverted cone mesa-shaped, and described buffer part 112 is circular cone shape, and described location division 111 is fixedly connected with described buffer part 112; Described foam block 12 is cylindric, and described foam block 12 is fixedly installed on the upper surface of described buffer part 112.

Referring to Fig. 4 and Fig. 5, the utility model embodiment provides a kind of damper element 1, rounding frustum structure is arranged in the location division 111 of damper element 1 can make the lower surface of location division 111 less, be convenient to damper element 1 when being arranged on vehicle body, location division 111 mounting hole corresponding with on vehicle body connects, described buffer part 112 is set to circular cone shape can make the area of the upper surface of buffer part 112 larger, there is provided larger plane of orientation to foam block 12, make the area of the upper surface of foam block 12 can be enough to cushion the parts of the frequent open and closes such as engine case to the collision of vehicle body.

On the basis of above-described embodiment, described location division 111 and described buffer part 112 one-body molded.Body 11 is made up of location division 111 and buffer part 112, location division 111 is positioned at the bottom of buffer part 112, play the effect connecting vehicle body and buffer part 112, location division 111 and buffer part 112 directly connection mode can have a variety of, preferably one-body molded, one-body molded can simplified processing process, simultaneously without the need to increasing unnecessary link, be conducive to the lightweight of buffer part 112.

The material of location division 111 and buffer part 112 has multiple choices, and preferably, in the utility model embodiment, location division 111 and buffer part 112 are ethylene propylene diene rubber and make.Buffer part 112 is often opened at buffering engine case etc., certain buffer action is played during the collision of the parts closed to vehicle body, buffer part 112 is needed to have certain distortion and the ability of recoverable deformation, location and the effect be connected are played in location division 111, less demanding to material, buffer part 112 is circular cone structure, location division 111 is rounding frustum structure, selected material is needed to have good processability, ethylene propylene diene rubber to meet the above-mentioned material to buffer part 112 and location division 111 stuctures and properties requirement, and cost is low, easy acquisition, can save production cost.

Further, described foam block 12 is adhesively fixed on the upper surface of described buffer part 112.Foam block 12 need are fixed on the upper surface of buffer part 112, fixing mode has a variety of, foam block 12 is preferably bonded at the upper surface of buffer part 112 by the utility model embodiment, above-mentioned connection mode is adopted to save link, and adhesives is convenient to obtain, on the basis of stable connection, a large amount of productive costss can be saved.

On the basis of above-described embodiment, the height of described foam block 12 is 10 ± 0.1mm.Foam block 12 be mainly cylindrical-shaped structure, because foam block 12 is being arranged on after on vehicle body, when being squeezed effect, can deform and extrude, there is certain buffer action to vehicle body simultaneously, above-mentioned functions requires that the height of foam block 12 is unsuitable too small, otherwise well cannot play buffer action, when the height of foam block 12 is excessive simultaneously, after foam block 12 is arranged on vehicle body, easily cause foam block 12 projection long, foam block 12 easily run-off the straight or be easily subject to the problem of scratching, engine cases etc. are often opened, also certain gap is had between the parts closed and vehicle body, based on this, the height of foam block 12 is decided to be 10 ± 0.1mm by the utility model embodiment, can on the basis meeting buffer action, foam block 12 is when damp impacts effect, ensure often to open at engine case etc., can not gap again between the parts closed and vehicle body.

Preferably, the diameter of described buffer part 112 upper surface is 16 ± 0.1mm, and the diameter of described foam block 12 is 15 ± 0.1mm.Foam block 12 needs the upper surface being fixed on buffer part 112, therefore both diameters need matching design, consider the supporting role of buffer part 112 pairs of foam blocks 12, the diameter of foam block 12 should not be greater than the diameter of buffer part 112 upper surface, the diameter of buffer part 112 upper surface is decided to be 16 ± 0.1mm, on this basis, the diameter of foam block 12 is set to 15 ± 0.1mm, the parts of the frequent open and closes such as engine case fully can be cushioned on the colliding forces basis of vehicle body, save productive costs.

Above, be described in detail in conjunction with specific embodiments to the technical solution of the utility model, described specific embodiment understands thought of the present utility model for helping.The derivation that those skilled in the art make on the basis of the utility model specific embodiment and modification also belong within the utility model protection domain.
