In the buffering stop block of above-mentioned automobile back door, on the described back wall outside plate and the position of the corresponding above-mentioned bump rubber brace panel that is connected, this brace panel and above-mentioned back wall outside plate shape are complementary.Brace panel is strengthened the impact resistance intensity of automobile back wall outside plate, prevents that distortion from appearring in automobile back wall outside plate.
In the buffering stop block of above-mentioned automobile back door, described brace panel is fixed on the above-mentioned back wall outside plate through the mode of welding.
In the buffering stop block of above-mentioned automobile back door; Offer a counterbore on the relative round platform end face of described bump rubber and boss; Clamping one nut in counterbore, this bump rubber passes brace panel and back wall outside plate and spiral through bolt and in nut, it is connected on the back wall outside plate.One end radial dilatation of counterbore forms a nut installation position, and nut is installed in this nut installation position, and the screw axial line of nut is coaxial with the axial line of counterbore.
In the buffering stop block of above-mentioned automobile back door, described bolt head is welded on the above-mentioned brace panel.
In the buffering stop block of above-mentioned automobile back door, offer a connecting bore on the described bump rubber, this bump rubber passes brace panel and back wall outside plate and spiral through bolt and in connecting bore, it is connected on the back wall outside plate.Have screw thread on the connecting bore inwall, bolt can be threaded in the connecting bore.
In the buffering stop block of above-mentioned automobile back door, described bolt head is welded on the above-mentioned brace panel.
In the buffering stop block of above-mentioned automobile back door, described bump rubber is a Rubber Parts.Rubber has certain elasticity, toughness and intensity, has withstanding corrosion, anti-be full of cracks, performance such as ageing-resistant simultaneously, guarantees the reliability of this automobile back door damping device.
Compare with prior art, the buffering stop block of this automobile back door has following having a few:
1, in the buffering stop block of this automobile back door, match with recess on the tailgate through the boss on the bump rubber, realize limit function to tailgate, prevent that problems such as distortion, closure be not tight from appearring in tailgate, promoted the car opertion performance greatly.
2, the bump rubber attachment face indoor design on the back wall outside plate of the buffering stop block of this automobile back door has brace panel, guarantees that back wall outside plate intensity meets the demands, and makes this device have fine reliability.
3, be embedded with nut in the bump rubber in advance, the bolt that welds on convenient and the back wall outside plate is connected, and is easy to the installation and the replacing of bump rubber.
4, the buffering stop block of this automobile back door also have simple in structure, cost is low, advantage such as easy to use, practical.
