Embodiment Construction
[0011] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, the present invention provides a kind of automobile wheel house outer connecting plate, and described automobile wheel house outer connecting plate is positioned at the side of car door, comprises exterior decorative plate 1 and welding support 2, and described welding support 2 is positioned at the back side of exterior decorative plate 1 , the welding bracket 2 is connected to the exterior trim panel 1 by ultrasonic welding, and a plurality of ultrasonic welding spots 3 are formed on the welding bracket 2 . By dividing the outer connecting plate of the automobile wheel house into two parts and connecting them by ultrasonic welding, the traditional one-time injection molding is replaced, and the shrinkage phenomenon on the surface of the outer connecting plate of the automobile wheel house is avoided, thereby ensuri...

The invention relates to the field of automobile external decoration members and concretely relates to an automobile wheel cover external connection plate comprising an external decoration plate and awelding rack. The welding rack is arranged on the back surface of the external decoration plate; the welding rack is connected with the external decoration plate via a supersonic welding way; a plurality of supersonic welding points are formed on the welding rack; the supersonic welding points are alternately arranged on the welding rack; one part of the supersonic welding points are arranged onthe edge of the welding rack; and the supersonic points on the edge of the welding rack are tangent to the welding rack edge. The automobile wheel cover external connection plate is divided into two parts and the two parts are connected via the supersonic welding way, so a traditional one-time injection moulding way is changed, shrinkage of the automobile wheel cover external connection plate canbe avoided, and forming quality can be guaranteed; the automobile wheel cover external connection plate can be more beautiful and has great practicality; with the welding points on the welding rack edge, the whole welding rack surface can be connected with the external decoration plate, so warpage of the welding rack edge can be prevented.
Description
technical field [0001] The invention relates to the technical field of automobile exterior decorations, in particular to an automobile wheel housing outer connecting plate. Background technique [0002] With the rapid development of automobile lightweight, it is unstoppable to seek lightweight materials to replace steel. At present, most of the automotive exterior parts are made of plastic materials, which can be injection molded at one time, and the processing is convenient and fast. However, when the outer connecting plate of the automobile wheel house is injection molded at one time, the product surface will shrink, so that it cannot meet the requirements of use, and the shape will also be deformed at the same time. Contents of the invention [0003] The object of the present invention is to provide an automobile wheel housing outer connecting plate with simple structure, good molding quality and no shrinkage on the product surface. [0004] In order to achieve the ab...
