Description
Technical field
The present invention relates to auto parts and components processing technique field, backplate at the bottom of a kind of vehicle body with noise-reduction function.
Background technology
Automobile bottom backplate is mounted in body bottom, the backplate playing protective action directly facing ground, it also has a critical function to be the air sinuous flow reducing automobile body bottom section in the process of moving, thus reduce windage, improve fuel economy and reach effect of energy-saving and emission-reduction, so in recent years under the main trend of energy-saving and emission-reduction, a lot of automobile main frame maker are all increasing this type of backplate, because having had the demand in market so having higher requirement the apparatus and process of this series products.Existing engine lower guard board typically uses steel design.Therefore high temperature is not problem on the impact of backplate under steel.But for backplate under plastics, it is desirable to the strictest.Currently in order to alleviate the weight of automobile, reduce automobile making cost, accessory this for lower backplate the most all uses working of plastics.
In order to strengthen the protection of bottom of automobile body, especially strengthening the protection to automobile engine, existing volume production vehicle is usually fixed with the automobile engine protective plate using the sheet material such as engineering plastic flitch or aluminium alloy plate to make at bottom of automobile body；The underbody backplate of traditional automobile acts primarily as protective action, while meeting strength demand, it is difficult to ensure that the noise that base plate produces when by impacting is the least, can cause the huge sound in car, affect driver；It addition, underbody backplate typically uses planarized structure, weight is big, brings inconvenience to installation, and, also can increase processing cost.
Summary of the invention
The purpose of invention: in order to overcome above deficiency, the present invention discloses backplate at the bottom of the vehicle body with noise-reduction function of the noise that a kind of intensity is big, processing cost is low and can effectively eliminate.
Technical scheme: in order to realize object above, the invention discloses backplate at the bottom of a kind of vehicle body with noise-reduction function, including panel reality；Described panel reality is inverted "L" shaped, and inner surface is provided with equally distributed ball-type pit；The both sides up and down of described panel reality are provided with vehicle body installing hole；The reinforcement that is provided around of described vehicle body installing hole thickens mechanism；The edge of described panel reality is provided with flanging；Described flanging is provided with cover plate connecting hole；The right-hand member of described panel reality is provided with an equally distributed reinforcement of row.
Backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, by carrying out spheroidising on described panel reality, is provided with equally distributed ball-type pit, on the one hand decreases weight, and then decreases the use of material, has reached cost-effective purpose；On the other hand, by the design of uniform multiple ball-type pits, it is possible to effectively eliminate noise, it is to avoid disturbed by noise in car, affect the judgement of driver.It addition, described vehicle body installing hole is arranged around reinforcement thickens mechanism, the right-hand member of panel reality arranges reinforcement, it is possible to the effective intensity improving panel reality, it is ensured that service life；Described panel reality is arranged around flanging, and the installation facilitating body connects, it is ensured that stablizing of structure, reduces installation period, has the biggest market competitiveness.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, the two ends, left and right of described panel reality are provided with hole, location.By positioning the location in hole, it is possible to ensure that panel reality is correctly installed in place, decrease the time of location and installation, and certain fixation can also be played.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, described flanging is provided with dodges hole.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, described dodges hole ovalize.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, it is 3mm～5mm that described reinforcement thickens the thickness of mechanism.Ensure the installation that backplate at the bottom of vehicle body can be stable, when being impacted by road surface, do not have the phenomenon of breaking releasing, improve the service life of product, reduce acquisition cost.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, described panel reality uses PPGF30 materials processing to be composited.What PPGF30 was RPP with glass fibre is compound, it is ensured that the intensity of underbody backplate itself, the most also has superpower heat resistance, improves the service life of product.
Further, backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, the thickness of described panel reality is 2mm～3mm.
Technique scheme is it can be seen that backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention has the advantages that
Backplate at the bottom of a kind of vehicle body with noise-reduction function of the present invention, by carrying out spheroidising on described panel reality, is provided with equally distributed ball-type pit, on the one hand decreases weight, and then decreases the use of material, has reached cost-effective purpose；On the other hand, by the design of uniform multiple ball-type pits, it is possible to effectively eliminate noise, it is to avoid disturbed by noise in car, affect the judgement of driver.It addition, described vehicle body installing hole is arranged around reinforcement thickens mechanism, the right-hand member of panel reality arranges reinforcement, it is possible to the effective intensity improving panel reality, it is ensured that service life；Described panel reality is arranged around flanging, and the installation facilitating body connects, it is ensured that stablizing of structure, reduces installation period.The present invention also has the features such as structural strength is big, length in service life, easy installation simultaneously, has the biggest market competitiveness.
