Description
Technical Field
The invention relates to the field of automobile manufacturing, in particular to a spare tire groove structure.
Background
Along with the development trend of light weight in the automobile industry, the automobile enterprises generally adopt the thinning of the thickness of parts and the reduction of weight during the design, thereby improving the dynamic property and the economical efficiency of vehicles. The size of the vehicle spare tire groove is generally larger, and with the implementation of a light-weight means for reducing the material thickness, a local low-order mode is easily generated to cause resonance, generate noise, reduce NVH performance, reduce reliability and durability and prolong the service life of a vehicle.
The resonance can be avoided by the following technical methods: the natural vibration frequency is changed by changing the material thickness of the material; the rigidity of the part is effectively improved by adding the reinforcing piece; the forward of the vibration wave is blocked by reasonably arranging the characteristic ribs. According to the technical scheme, the weight of the whole vehicle is increased by increasing the material thickness, and the development trend of light weight is not met; the addition of the reinforcing part can increase the mass of the whole automobile and can increase the investment cost of a stamping die and a welding clamp; the difficulty of realizing the stamping process can be increased due to the high requirement on the depth of the reinforcing ribs, and the consistency of products is reduced.
Typical prior art techniques are for example: chinese patent document CN102785714A discloses "a reinforcing structure for spare tire grooves on rear floor of car" at 11/21/2012, which is characterized in that: the reinforcing structure is that the spare tire groove is in a shape of a tendency closing-up from front to back; a T-shaped rib is arranged by taking the spare tire installation point as a center, and line ribs with equal-width gaps are uniformly distributed at the rear end of the spare tire installation point; being equipped with the straight line muscle around spare tyre mounting point, owing to adopt above-mentioned structure, this additional strengthening has following advantage: 1. the resonance phenomenon of a spare tire groove in the running process of the automobile is avoided at lower cost, and the NVH performance of the whole automobile is improved; 2. the stamping process is easy to realize, and is worthy of industrial popularization and application. Chinese patent document CN105835959A discloses "an automobile rear floor spare tire groove structure" in 2016, 8 months and 10 days, which includes: a rear floor (1) of the vehicle; a spare tire groove (2) which is arranged on the rear floor (1) of the automobile and is downwards concave; wherein the spare tire groove (2) comprises: a semi-circular front portion; a middle part extending outwards along the tangential direction of two ends of the semicircle; a rear portion extending outwardly from the end of the central portion and closing in; the middle point (21) of the circle at the front part is used as the center to be provided with the T-shaped rib (3) which is in a transmitting shape, the middle part and the rear part of the spare tire groove (2) are provided with at least two transverse convex ribs (4), the stamping forming process is simple, the rigidity and the mode of the spare tire groove (2) can be obviously improved, the resonance phenomenon is avoided, the rear collision is facilitated, the self sufficient deformation energy absorption is realized, and the purpose of protecting an oil tank and passengers is achieved. Chinese patent document CN108082307A discloses "a spare tire groove" in 2018, 5.29.s, which includes a support plate, an upper flange and a lower flange, the edge of the support plate is alternately provided with the upper flange and the lower flange, the top of the support plate is provided with a T-shaped groove, one side of the top of the support plate, which is located at the T-shaped groove, is provided with an elongated groove, the bottom of the support plate, which is directly opposite to the elongated groove, is provided with a reinforcing groove, two sides of the top of the support plate are symmetrically provided with grooves, one end of each groove is provided with a liquid leakage hole, two corresponding ends of the T-shaped groove are respectively provided with a positioning hole, the support plate, the upper flange and the lower flange are in an integrated structure, and the spare tire groove is formed by stamping one plate, so that the weight of the whole vehicle is reduced, and the light weight of the vehicle body is facilitated; meanwhile, the manufacturing cost of the bicycle is reduced, the upper flanging and the lower flanging are alternately arranged at the edge of the supporting plate, the rigidity of the spare tire groove is enhanced, the T-shaped groove, the long-shaped groove, the reinforcing groove and the groove are arranged, the supporting plate is prevented from being broken in the using process, and the problem of resonance cracking can be avoided.
Aiming at the analysis of the prior art, the problem of resonance of a spare tire groove in the driving process of an automobile is expected to be avoided by adopting a mode of adding complex characteristic ribs. Three drawbacks still exist: 1, the prior art does not fully identify a reasonable design form of the reinforcing rib, and the feasibility of a design scheme is repeatedly verified by means of CAE simulation, so that the shortage of design resources is easily caused. The reason is that the spare tire groove is influenced by arrangement and has various design schemes with different depths, the scheme with shallow spare tire groove depth has compact structure due to the circumference lap joint, the influence of the circumference lap joint structural part on the spare tire groove mode is larger than that of the characteristic rib, the reinforcing rib meeting the local mode is easy to manufacture, and more reinforcing rib modes are selected under the state. Along with the increase of spare tyre groove degree of depth, the relevance of spare tyre groove bottom with the surrounding overlap joint structure is lower and lower, and the local mode of spare tyre groove receives the influence grow of bottom muscle or bottom reinforcement, and the strengthening rib mode more has the commonality under this state. 2, the prior art does not fully consider the scheme of vehicle body weight reduction. The reason is that the local mode of the spare tire groove does not reach the target value, the simplest and most direct scheme is to add a support, connect the bottom of the spare tire groove with a beam frame structure, and improve the local mode of the spare tire groove through the stability of the beam frame. Or a reinforcing plate is added at the bottom of the spare tire groove to reinforce the connection between the bottom of the spare tire groove and the side wall, similarly to increase the local material thickness, so as to promote the local mode. 3, the unreasonable arrangement of the ribs of the spare tire groove cannot be fully considered in the prior art, so that the manufacturing difficulty can be increased. The reason is that most of the existing spare tire groove ribs are arranged to extend from the center to the side wall of the spare tire groove in a radial mode, and in order to improve the height of the local mode, reduce the characteristic R angle of the rib, overlap a plurality of ribs and the like, the measures are powerful in improving the local mode and are not beneficial to manufacturing a mold. For a sheet metal part with a characteristic fall, the transition of an R angle needs to be smooth so as to facilitate the flowing of steel materials in the stamping process, the height of the rib is increased, the characteristic R angle of the rib is reduced, the measures of overlapping a plurality of ribs conflict with a reasonable stamping mode, the risk of cracking and wrinkling of parts is increased, and in order to realize certain complex characteristics, the number of dies needs to be increased for multiple times of stamping so as to realize the design state.
