Description

Technical Field

[0001] The utility model relates to an automobile accessory, in particular to a reinforced automobile front panel. Background Art

[0002] The car's front panel system is the main component that isolates the passenger compartment and the engine compartment. It can effectively reduce the noise generated by the engine and transmitted into the passenger compartment. At the same time, since the brake and accelerator pedals are directly fixed to the front panel with bolts, if the dynamic stiffness of the front panel is weak, it will easily cause the pedals to vibrate, thereby affecting driving safety and comfort. However, if the thickness of the front panel is thickened, the weight will increase, which is not conducive to improving the overall performance of the product and will inevitably lead to an increase in cost. Summary of the Invention

[0003] The utility model addresses the technical problem that the existing automobile front panel is increased in thickness to increase the dynamic stiffness, which leads to increased costs and affects the overall performance of the product. It provides a reinforced automobile front panel that improves the dynamic stiffness of the front panel through structural improvements without substantially increasing the weight of the product, thereby effectively improving the connection reliability of the product.

[0005] Preferably, the side surface of the reinforcing plate is welded to the front panel.

[0006] Preferably, the bosses are evenly distributed on the top of the reinforcing plate, and the distance between each boss is not less than the width of one boss.

[0007] Preferably, the surface height of the circular protrusion is smaller than the surface height of the rib, and the rib is a hollow structure.

[0008] Preferably, the anti-loosening gasket is made of rubber.

[0009] The beneficial effects of the utility model are:

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] like Figure 1-3As shown, a reinforced automobile front wall includes a front wall plate 1, a reinforcing plate 2, a front wall plate upper plate 3, and a water channel cover plate 9. The front wall plate 1 and the reinforcing plate 2 are provided with corresponding functional holes 6. The reinforcing plate 2 is provided with bosses 4 at the upper part. The bosses 4 are provided with circular protrusions 7. The circular protrusions 7 are provided with countersunk holes 11. The front wall plate 1 and the front wall plate upper plate 3 are provided with through holes corresponding to the countersunk holes 11. The through holes are light holes. The countersunk holes 11 are provided with countersunk screws 8. The countersunk screws 8 are provided with anti-loosening washers 12. The water channel cover plate 9 is provided with threaded holes corresponding to the countersunk screws 8. The threaded holes are blind holes and do not affect the overall performance of the water channel cover plate 9. The reinforcing plate 2 is also provided with protruding ribs 10. The protruding ribs 10 and the circular protrusions 7 are located on the reinforcing plate 2 opposite to the front wall plate 1.

[0021] The side surface of the reinforcing plate 2 is welded to the front wall plate 1. The bosses 4 are uniformly distributed on the top of the reinforcing plate 2. The distance between each boss 4 is not less than the width of one boss 4. Sufficient relative recessed positions are left to effectively avoid more than three layers of welding and improve connection reliability. The surface height of the circular protrusions 7 is less than the surface height of the protruding ribs 5. The protruding ribs 5 are hollow structures. The anti-loosening washers 12 are made of rubber material. During assembly, the bosses of the reinforcing plate 2 are fixed to the front wall plate 1, the front wall plate upper plate 3, and the water channel cover plate 9 through the countersunk screws 8. The water channel cover plate 9, the front wall plate upper plate 3, and the front wall plate 1 are connected through welding at the positions without bosses of the reinforcing plate 2, i.e., the relative recessed positions. Further welding can be performed between the bosses of the reinforcing plate 2 and the front wall plate 1 and the front wall plate upper plate 3 according to strength requirements. During this process, the countersunk screws 8 are used as positioning elements and are not tightened to provide sufficient operation space for subsequent welding. After welding is completed, the countersunk screws 8 are tightened to fix the components. This assembly method is firm and reliable, has high precision, and is beneficial to improving the overall performance of the product.

[0022] The present application provides a boss 4 on the upper part of the reinforcing plate 2 to reduce the hidden danger of loose fixation caused by multi-layer welding, and provides a countersunk screw 8 on the boss 4 to fix the front panel 1, the front panel upper plate 3 and the water trough cover plate 9. This arrangement not only improves the connection reliability, but also assists in positioning. During welding, the problem of poor welding accuracy due to position movement will not occur, which greatly improves the reliability of the structure and the connection accuracy. The countersunk screw 8 is arranged in the countersunk hole 11, and an anti-loosening gasket 12 is provided on the countersunk screw 8 to avoid loosening of the screw due to vibration during use, thereby improving the reliability of the structure and the connection accuracy. Product reliability; the anti-loosening gasket 12 is made of rubber material with good friction, high elasticity, and can better reduce noise; the setting of the rib 5 effectively ensures the dynamic stiffness of the pedal installation without increasing the thickness of the reinforcing plate 2, improves the pedal vibration performance, and also improves the sound insulation performance of the front panel 1 in the low frequency band; the setting of the circular protrusion 7 can meet the connection strength requirements of the countersunk screw 8, and the surface height of the circular protrusion 7 is not higher than the surface height of the rib 5, which can reduce space occupancy and minimize the product volume; the number of circular protrusions 7 and countersunk screws 8 can be set according to the specific size of the water trough cover 9.
