Abstract
The utility model relates to an automobile rear floor connecting plate, which consists of a U-shaped connecting plate main body and a flange turned outward from the periphery of the connecting plate main body. Two side faces of the connecting plate main body have right angled triangle shapes; and the bottom surface of the connecting plate main body is provided with a back door dragline mounting hole and a wire harness mounting hole. After the rear floor connecting plate is welded with an automobile rear floor and a rear skirtboard, the torsional rigidity of the rear part of the whole automobile can be improved and the noise vibration and harshness (NVH) performance of the whole automobile is improved.
Description
Technical field
The utility model relates to auto parts and components, is specifically related to a kind of automobile rear floor connecting panel.
Background technology
After reducing automobile, bump the lives and properties damage of being brought, must carry out scientific and reasonable design bumping structure behind the automobile.Bumping structure behind the existing automobile mainly is: floor, back connecting panel is Z-shaped to (automobile fore-and-aft direction) section along vehicle body coordinate X; Along vehicle body Y to (vehicle right and left direction) have with the back floor, the back skirtboard landing edge; Top is connected through spot welding with the floor, back with the landing edge of its Y forward; The bottom is connected through spot welding with gusset, is connected through spot welding with the back skirtboard along the landing edge of Y negative direction.Because floor, back connecting panel is Z-shaped to section along X, so it has only a face overlap joint with back skirtboard overlap joint.
The automobile rear floor connecting panel plays an important role to the intensity on car load collision, car load torsional stiffness, floor, back; And floor, existing back connecting panel is after welding with floor, back and back skirtboard; Do not have good energy-absorbing effect, so make the torsional stiffness at car load rear portion lower.On the other hand, the Denso wire harness on the automobile, tailgate drag-line are to install through the mounting hole that is opened on the floor, back, yet mounting holes will reduce the NVH performance of car load on the floor, back.
Summary of the invention
The purpose of the utility model provides a kind of automobile rear floor connecting panel, with after itself and automobile rear floor and the back skirtboard welding, can improve the torsional stiffness at car load rear portion, helps improving the NVH performance of car load simultaneously.
The said automobile rear floor connecting panel of the utility model; Constitute by outside flange around connecting panel main body that takes the shape of the letter U and the connecting panel main body; The connecting panel main body takes the shape of the letter U, and its two sides are shaped as right-angled triangle, offers tailgate drag-line mounting hole and wire harness mounting hole in connecting panel main body bottom surface.
Wherein offering welding process hole on the hypotenuse bonded assembly flange of a side with the connecting panel main body.Welding process can be avoided four layers of weldering.
After the said automobile rear floor connecting panel of the utility model welds with the back skirtboard through its flange and automobile rear floor; Form a kind of leg-of-mutton box like structure; This kind structure has very high strength and stiffness, and the torsional stiffness at car load rear portion is greatly improved, when colliding crossbeam generation moderate finite deformation in the back; Can disperse the collision energy transmission, avoid floor, back, back skirtboard to produce very big distortion.Because tailgate drag-line mounting hole and wire harness mounting hole are to be opened in connecting panel main body bottom surface, thereby avoided that direct perforate is used for the installation of tailgate drag-line and wire harness on the floor, back, so help improving the NVH performance of car load.
Description of drawings
Combine accompanying drawing that the utility model is done further explain at present.
Fig. 1 is the shaft side figure of the said automobile rear floor connecting panel of the utility model;
Fig. 2 is welded on the constitution diagram on floor, back and the back skirtboard for this floor, back connecting panel.
The specific embodiment
Like accompanying drawing 1 and shown in Figure 4; This automobile rear floor connecting panel is made up of outside flange 2 around connecting panel main body that takes the shape of the letter U 4 and the connecting panel main body 4; Connecting panel main body 4 takes the shape of the letter U; Its two sides 1 are shaped as right-angled triangle, offer tailgate drag-line mounting hole 3 and wire harness mounting hole 5 in connecting panel main body 4 bottom surfaces, are wherein offering rectangle welding process hole 6 on the hypotenuse bonded assembly flange 2 of a side 1 with connecting panel main body 4.
Claims (2)
1. automobile rear floor connecting panel; It is characterized in that: constitute by flange (2) outside around connecting panel main body (4) that takes the shape of the letter U and the connecting panel main body; The connecting panel main body takes the shape of the letter U; Its two sides (1) are shaped as right-angled triangle, offer tailgate drag-line mounting hole (3) and wire harness mounting hole (5) in connecting panel main body bottom surface.
2. according to the said automobile rear floor connecting panel of claim 1, it is characterized in that: wherein offering welding process hole (6) on the hypotenuse bonded assembly flange (2) of a side with connecting panel main body (4).
