Detailed Description
As shown in figure 1, the automobile hat rack is characterized in that rib grooves 20 which are longitudinally arranged are punched and formed in the plate surface of a hat rack body 10, accessory mounting positions are arranged on the front side of the hat rack body 10, and lightening holes 11 which are arranged at intervals along the width direction of a vehicle are arranged on the rear side of the hat rack body. In the above solution, the longitudinal arrangement of the rib grooves 20 is mainly used to improve the stiffness performance and the natural frequency of the structure of the hatrack, which has a great influence on the overall performance of the hatrack. According to the method, the arrangement position of the reinforcing ribs is determined according to the analysis result obtained by carrying out morphology optimization on the hat and coat stand optimization feasible region, then the shape of the reinforcing ribs is subjected to regularization treatment mainly based on X-direction strips, and on the premise that the requirements of design and stamping processes are met, good rigidity performance and high local mode are obtained.
The periphery of the coat and hat stand body 10 is provided with a flat edge 12 to form a welding part with a vehicle body. Besides being used for welding, the edge 12 also creates conditions for bending the plate body on the inner side of the edge, and improves the local strength of the edge area on the premise of ensuring the welding quality.
The hallstand body 10 is provided with a sound installation hole 13 at the position which is arranged at the rear part of the middle part and close to the two sides. This provides amusement and comfort equipment for back row passenger, improves the ride experience.
The area between two sound installation holes 13 is provided with a strip-shaped vent hole 14, and the vent hole 14 is arranged at the bottom of the rib groove 20. The provision of the ventilation holes 14 also further enhances the effect of light weight, since the ventilation holes 14 are disposed in the central rear region of the entire region, which is also a region away from the support, which contributes to the attenuation thereof against deformation by the action of gravity.
The areas with smaller influences on the structural performance and the technological requirements of the hat and coat stand are found out, and the arrangement of the lightening holes is carried out, so that the lightweight requirements are met, and meanwhile, the design and performance requirements can be met.
The rear side of the edge 12 of the front part of the hat rack body 10 is provided with an inclined surface 15 which is erected upwards and backwards, the front side of the edge 12 of the rear part of the hat rack body 10 is provided with a groove part 30 with an upward notch and a long groove along the width of the vehicle, and a large-area for arranging the rib groove 20, the vent hole 14 and the sound installation hole 13 is arranged between the front side groove edge of the groove part 30 and the upper edge of the inclined surface 15. In fact, the lightening holes 11 are arranged on the groove bottom of the groove part 30, the scheme has small influence on the structural performance and the technological requirement of the hat rack, and the lightening holes 11 are arranged, so that the light weight requirement is met, and meanwhile, the design and performance requirements can be met.
The rib groove 20 comprises a wide groove 21 with an upward notch and a narrow groove 22 with a downward notch, and the groove walls of the wide groove 21 and the narrow groove 22 are shared groove walls. The arrangement of the wide groove 21 and the narrow groove 22 is beneficial to reducing stress concentration during punch forming, and the large surface of the plate body can be in a flush state on the whole.
A child seat hook mounting position 23 is arranged at the front end of the groove bottom of at least 3 wide grooves 21, and a safety belt retractor mounting position 24 is arranged at the transition position of the inclined plane 15 and the upper plate surface between the child seat hook mounting positions 23 at the left position, the middle position and/or the middle position and the right position. The front end of the groove bottom of the wide groove 21 is provided with the child seat hook mounting position 23, so that the child seat hook is convenient to mount, sufficient strength is ensured, and children can sit safely at the left, middle and right positions of the rear row.
The vent holes 14 are provided with flanges 141 which are arranged upwards or downwards, and the lightening holes 11 are provided with flanges 111 which are arranged upwards or downwards. The hole edge of the hole opening is provided with the flanging, so that the local rigidity can be further improved, and the overall strength and rigidity of the automobile hat rack are improved. The vent 14 is primarily designed to require a vent greater than 220 square centimeters. According to the mechanical property principle, the ventilation holes 14 are far away from the central area of the hat and coat stand as much as possible, the influence of the holes on the local rigidity is weakened, and the edges of the ventilation holes 14 are provided with flanging characteristics.
