Furthermore, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, and therefore the features defined "first", "second" may explicitly or implicitly include one or more of the features described.
In the description of the present invention, it should be noted that, unless otherwise explicitly stated or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
As shown in fig. 3, according to a shock absorber seat in the prior art, through CAE (Computer Aided Engineering) analysis, the plastic strain and the residual displacement in the F region cannot meet performance requirements, and the shock absorber seat is a key part for mounting a shock absorber spring and has high strength requirements, so that it is critical to improve the strength of the shock absorber seat. Therefore, the invention optimizes the structure of the F area of the traditional shock absorber seat, which comprises the following specific steps:
referring to fig. 1-2, the shock absorber seat of the invention comprises a body 1, wherein the body 1 is provided with a through hole 2 for the shock absorber to extend into and a plurality of mounting holes 3 for fixing the shock absorber, the through hole 2 and the mounting holes 3 are arranged in the same manner as in the prior art, after the shock absorber passes through the through hole 2, a spring of the shock absorber is mounted in the mounting hole 3 through a fastener, the mounting manner is also in the same manner as in the prior art, the mounting difficulty cannot be increased due to structural change, and the labor cost is further increased.
Further, a first profile 4 located outside the mounting hole 3 at the front outside of the body 1 is recessed on the body 1, and a second profile 5 located at the front outside of the body 1 at the front of the mounting hole 3 is recessed on the body 1. Although the thickness of the shock absorber seat at the position is reduced due to the concave profile, the stress edge at the position can be increased, the stress applied at the position is dispersed, the bending deformation can be resisted, and the strength at the position is increased so as to meet the requirements of plastic strain and residual displacement performance.
The body 1 is optimized at multiple positions of the weak area, the defect is that only the first molded surface 4 or the second molded surface 5 can be optimized to improve enough strength, and the enough strength can be ensured only by utilizing the synergistic effect between the first molded surface 4 and the second molded surface 5.
The first and second profiles 4 and 5 may be flat, and the strength of the shock absorber seat may be further increased by changing the structure thereof, for example, the first profile 4 having a relatively large area may be formed in a step shape, and the step shape may be a step in the front-rear direction or a step in the inside-outside direction. When the ladder is a ladder in the inner and outer directions, if the first molded surface 4 is sunken on the body 1 to form a ladder with shallow inside and deep outside, the ladder mainly increases the stressed edge in the front and back directions, and can increase the capability of resisting bending deformation in the front and back directions; when the shock absorber seat is a step in the front-back direction, the stress edges in the inner-outer direction are added to the step, the capability of resisting stress bending deformation in the inner-outer direction can be increased, and in addition, due to the stress edges in the front-back direction added by the recess, the strength of the whole shock absorber seat in two directions can be increased only by the first molded surface 4, so that the step in the front-back direction is preferably selected by the step type of the first molded surface 4, and if the first molded surface 4 is recessed on the body 1, the step with a shallow rear part and a deep front part or the step with a deep rear part.
The thickness of the deeper step can be 1/3-1/2 of the thickness of the body 1, and the thickness of the shallower step can be 2/3-3/4 of the thickness of the body 1, so that the strength of the thinnest part can be ensured not to be too poor, and the overall performance requirement can be met.
When the shock absorber seat is connected with the peripheral parts, the deeper stepped surface and the peripheral parts closest to the deeper stepped surface can be connected by the connecting plate.
In order to facilitate the production operation, the first profile 4 is recessed to cover the edge of the body 1, and compared with the mode of only recessing and not covering the edge of the body 1, the shock absorber seat is convenient to produce and install.
The front part of the body 1 is provided with an air chamber cover plate mounting hole 6, and as an arrangement mode of the second molded surface 5, the second molded surface 5 is formed between the air chamber cover plate mounting hole 6 and the mounting hole 3 positioned at the outer side of the front part of the body 1, so that the molded surface optimization with the largest area can be carried out without changing the mounting mode of the shock absorber, and the optimization effect can be optimal.
In order to increase the stressed edge as much as possible, the second profile 5 and the first profile 4 close to the second profile are in a stepped shape instead of being on the same plane with the first profile 4 close to the second profile, for example, the second profile 5 is higher than the first profile 4 close to the second profile in the vertical direction, so that the design can not only ensure that the strength of the shock absorber seat is optimal, but also ensure that the welding surface on the front side of the shock absorber seat has enough width to be welded firmly with the peripheral sheet metal parts.
Because 5 areas of second profile are less, inconvenient adoption ladder form increases the atress limit in order to increase intensity, so establish second profile 5 into the low inclined plane in high preceding back, this kind of mode of setting has increased the drop of 1 side of body and 5 deepest of second profile, has increased the thickness on atress limit between the two promptly, can further increase the intensity here, and is same, can not reduce the width of face of weld, guarantees to weld reliably.
When the shock absorber is mounted, the second molded surface 5 can be sunken to cover the edge of the body 1 or not to cover the edge of the body 1 because the second molded surface 5 is not directly fastened with the peripheral parts. But in view of the convenience of production, it is preferable to recess to cover the edge of the body 1. Of course, in order to increase the stressed edge, when the second molding surface 5 is recessed to the edge not covering the body 1, the edge of the front part and/or the outer side of the second molding surface 5 may be higher than the second molding surface 5 but lower than the body 1 in the vertical direction, at this time, the second molding surface 5 and the edge thereof are recessed integrally relative to the body 1, compared with the manner of only recessing the second molding surface 5 or the manner of recessing the second molding surface 5 to the edge covering the body 1, the stressed edges on different planes are increased, and the stress applied thereto can be dispersed to multiple surfaces as much as possible. In addition, the welding surface on the front side of the shock absorber seat can be ensured to have enough width so as to be firmly welded with the peripheral sheet metal parts.
The first molded surface 4 and the second molded surface 5 are in round corner transition with other parts of the body 1, namely, the connecting surfaces are cambered surfaces, if the respective connecting surfaces form included angles with the first molded surface 4, the second molded surface 5 and the body 1, stress is easily concentrated at the included angle when the stress is applied, so that the included angle is damaged, and the connecting surfaces are cambered surfaces and can disperse stress.
From the above description, it can be seen that the shock absorber seat of the present invention has the following advantages: by optimizing the profile of the weak area of the strength of the shock absorber seat and setting the profile as a depression, compared with the shock absorber seat with the profile as a plane in the prior art, although the thickness of the depressed profile is thinned, the whole stress edges of the shock absorber seat are increased, the stress on the whole shock absorber seat is dispersed, the whole strength of the shock absorber seat is increased, and the cracking risk is reduced; the profile of the shock absorber seat is sunken, so that the material usage amount of the shock absorber seat is reduced, and compared with a mode of thickening or increasing a boss to increase strength in the prior art, the shock absorber seat has better strength increasing effect and can achieve the purpose of integral light weight; the shock absorber seat optimized by the molded surface does not change the mounting structure of the shock absorber, does not influence the normal mounting of the shock absorber, and is more convenient to use.
Another aspect of the present invention provides a damper assembly comprising the above-described damper base, and a damper (not shown), the damper body being passed through the through-hole 2 and then fixedly attached to the mounting hole 3 by a fastener.
The invention also provides a vehicle comprising the shock absorber assembly.
