Description

A connection structure for an automobile roof

technical field

The utility model relates to the field of auto parts, in particular to a connection structure between an auto plastic top cover and a car body.

Background technique

Automobile lightweight is the trend of automobile development, and body plastic parts are one of the main ways of automobile lightweight. Since the density of plastic parts is only about one-seventh of that of metal, the use of plastic parts for automobile outer covers has the following disadvantages: installation points cannot be arranged inside the plastic outer cover, otherwise there will be depressions on the surface of the connection points, which will affect the appearance quality; The exposed mounting points on the outside of the parts also affect the appearance quality; the plastic outer cover is easy to warp and deform, and reinforcement ribs need to be added inside, the surface of the outer cover is sprayed and baked, and there is a risk of sink marks on the surface, which affects the appearance quality; the plastic outer cover It can only play a decorative role, and its strength is relatively weak. It needs to be supported by internal structural parts to meet the appearance quality requirements; in order to maintain the appearance quality, the plastic outer cover does not have an internal installation structure, and needs to be sealed by internal structural parts to prevent dust and dust. Water has entered the interior of the passenger compartment. Therefore, it is necessary to design a connection structure between the reinforced plastic roof and the vehicle body to improve these problems.

Utility model content

The purpose of this utility model is to overcome the above-mentioned problems, propose a kind of connection structure of automobile top cover, strengthen the connection between the top cover and the decorative panel on the C-pillar by connecting the fixing parts of the vehicle body.

The technical scheme of the utility model includes a car body frame and a cross beam, an upper decorative plate fixed on the C-pillar of the car body, a plastic fixing part with honeycomb holes on the surface covering the top of the car body frame, passing through the concave installation area on the front and rear sides and the middle part through screws respectively. Connect a number of brackets and beams fixed on the body frame. A number of bayonets are evenly arranged on both sides of the fixing piece. The bayonets are installed with the concave top cover on both sides of the edge through the spring card and the A-shaped buckle from bottom to top. The installation part and the installation part on the top of the upper decorative panel are connected through screws, a sealing strip is arranged on the top, and the front part of the top cover is connected to the front beam through screws.

Further, in order to facilitate installation and positioning, a cross-cone positioning column is arranged on the surface of the fixing part installation area, and is positioned and installed through the opening of the top cover above.

Further, in order to enhance the support for the upper trim panel of the C-pillar and prevent it from warping, deforming and collapsing, both sides of the fixing member extend outward to below the upper trim panel.

Furthermore, in order to strengthen the connection of the decorative panel on the C-pillar, the upper surface of the body frame is welded with a bracket with transverse or longitudinal knuckles, the longitudinal knuckles of the bracket are snapped into the buckles on the inner side of the middle of the trim panel, and the horizontal knuckles are connected by screws Fix the extensions on both sides.

In addition, in order to further enhance the support for the upper decorative panel of the C-pillar, a metal stop with a downward knuckle is welded on the lower surface of the body frame, and the lower part of the upper decorative panel is close to the metal stop.

Further, in order to prevent liquid from seeping in, a sealant is applied to the connection between the upper decorative panel and the top cover.

Further, to prevent rainwater from seeping into the passenger compartment from the assembly gap of the plastic roof and the decorative panel on the C-pillar, the bottom of the installation area on both sides of the fixing part forms a water tank.
