Description

[Detailed Description of the Invention] This invention relates to a panel structure for an automobile body, and particularly to a quarter panel forming a rear side plate of the automobile body.

In conventional car body structures, quarter panels formed from a single plate are usually used.

Incidentally, there is a strong demand for lower fuel consumption in recent automobiles from the standpoint of energy conservation, and in order to meet this demand, reducing the weight of the vehicle body has become an important issue.

The present invention has been developed in response to such demands, and the purpose of the present invention is to reduce the weight of the quarter panel without reducing the rigidity of the quarter panel, and to make it possible to reduce the weight of the quarter panel without reducing the rigidity of the quarter panel. The object of the present invention is to provide a panel structure that provides the following advantages.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

In the panel structure of the embodiment, that is, the quarter panel, as shown in FIGS. 1 to 4, the panel upper part 1 located above the middle height of the vehicle body and the panel lower part 2 located below from the same height are relayed. It is formed by welding, specifically, the lower end 1a of the panel upper 1 and the upper end 2 of the panel lower 2.
a are overlapped, and the overlapped upper and lower edges are welded.

The overlapping portion of the upper end 2a of the panel lower 2 is inwardly recessed into a chevron shape, thereby forming a longitudinal space 3 with a trapezoidal cross section in the overlapping portion. The welding edge is slightly retracted, and on the retracted surface,
The molding 4 is fitted.

The upper welded edge is waterproofed with a sealer 5, and the panel lower 2 is made of a rust-resistant plate.

By the way, a slit-shaped exhaust hole 6 is opened at the rear of the lower end 1a of the panel top 1.
In the part where the longitudinal space 3 forms a ventilation duct for the passenger compartment and the exhaust hole 6 is provided, both panel parts 1 and 2 are welded in a floating state (see Fig. 3). , rainwater that has entered through the exhaust hole 6 is drained downward.

In addition, in the gate portions (Fig. 4) at the front ends of both panel parts 1 and 2, the collars 1b and 2b overlap each other.
is formed, and also functions as a reinforcing material for the door latch, which is fastened with bolts 7 at the overlapped portion.

In the panel structure of the example configured in this way, the rigidity of the panel surface is reinforced by the overlapping part forming the box-shaped structure, so even if a thin plate is used for the panel material, it will not be affected by rear collisions or side collisions. In addition to being able to sufficiently prevent the deformation of the cabin in the event of a collision, there are many other benefits as described below.

(a) Vibration damping properties of panels Increased rigidity reduces panel noise.

(b) Utilization of space Longitudinal space 3 can be used for other purposes such as ducting.

(c) Durability of the panel The service life of the quarter panel can be extended by replacing the panel lower 2 that has been damaged and deteriorated by splashing water or flying stones.

(d) Commonality of panel parts As shown in Figures 5a to 5c, quarter panels of different vehicle models are connected to a common panel lower 9,
Since it can be manufactured using both the panel tops 10A to 10C for each vehicle type, the manufacturing efficiency of the quarter panel is improved.

As described above, according to the panel structure according to the present invention, the quarter panel is formed by welding the upper and lower panel parts, and the overlapping part of both panel parts is formed into a box-shaped reinforced structure. This makes it easy to reduce the weight of the panel and has the practical effect of increasing the ease of manufacturing the vehicle body.

Claims (1)

[Scope of utility model registration request] In the quarter panel forming the rear side plate of the vehicle body, the joint portion is formed by relay welding of both the panel upper and panel lower panel components, and runs longitudinally in the longitudinal direction of the vehicle body. The overlap part is formed into a box-shaped closed section structure to increase the rigidity of the side panels of the vehicle body, and an exhaust port and a drainage passage are provided in the closed section section, and the front end of the closed section section in the longitudinal direction of the vehicle body. A panel structure characterized in that a door latch installation location is set by providing an overlapping part in the panel structure.
