Abstract

The invention relates to a car rear surrounding plate and an adjacent part connection combination. The car rear surrounding plate and the adjacent part connection combination comprise a rear base plate body (1), longitudinal girder assembles (2) arranged on a left side and a right of the rear base plate body (1), a rear surrounding plate (3) connected with the rear base plate body (1) in a lapped mode and a rear insurance collision beam assembly (4) arranged on the outer side of the rear surrounding plate (3) and matched with the longitudinal girder assemblies (2). The rear insurance collision beam assembly (4) is directly connected with the longitudinal girder assemblies (2) in a matched mode. Demising zones for the rear insurance collision beam assembly (4) to be directly matched with the longitudinal girder assembles (2) are arranged on the lower portions of the left side and the right side of the rear surrounding plate (3). The car rear surrounding plate and the adjacent part connection combination solve the problem that welding errors can calculate easily on the rear surrounding plate and consequentially, the rear insurance collision beam assembly is difficult to assemble, and can effectively improve torsional rigidity of a car body framework and benefit improving of bearing capacity of a car body.

Description

A kind of automobile rear end panel and adjacent elements thereof connect combination
Technical field
The invention belongs to the auto parts and components field, especially relate to a kind of automobile rear end panel and adjacent elements thereof and connect combination.
Background technology
Existing automobile tail combination is protected collision crossbeam assembly by rear end panel, back base plate body, left-right longeron assembly and back and is formed.Common, the rear end panel left and right sides connects the left-right longeron assembly respectively, and with back base plate body overlap joint, rear end panel bottom left and right regions and longeron rear end overlap in the middle of the bottom.On the one hand, because rear end panel is protected between the collision crossbeam assembly in left-right longeron assembly rear end and back, rear end panel is as connecting plate, easily accumulative total is welded error, causes the back to protect problems such as collision crossbeam assembly assembling difficulty, on the other hand, along with the development of automobile weight-saving, traditional rear end panel covers whole back wall part, and area occupied is bigger, directly causes the increase of automobile fuel consumption.
Summary of the invention
The purpose of this invention is to provide a kind of automobile rear end panel and adjacent elements thereof and connect combination, solved existing rear end panel and easily totally welded the problem that error causes back guarantor's collision crossbeam assembly assembling difficulty.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automobile rear end panel and adjacent elements thereof connect combination, comprise back base plate body, be arranged on the longeron assembly of the base plate body left and right sides, back, rear end panel with back base plate body overlap joint, and be arranged on the rear end panel outside and the back guarantor that matches with the longeron assembly collides the crossbeam assembly, collision crossbeam assembly is protected in the back and the longeron assembly directly is connected, and the left and right sides bottom of rear end panel is provided with the zone of stepping down that back guarantor's collision crossbeam assembly and longeron assembly are directly cooperated.
In order to reduce tare, reduce oil consumption, the bottom profiled of rear end panel is suitable near the edge of rear end panel with back base plate body.
Preferably, the longeron assembly is provided with the one group of bolt that cooperates with back guarantor's collision crossbeam assembly near the end of rear end panel.
Preferably, the longeron assembly is connected by welding manner with back guarantor's collision crossbeam assembly.
Beneficial effect of the present invention: directly be connected by back guarantor's collision crossbeam assembly and longeron assembly, solve existing rear end panel and easily totally welded error, and then cause the back to protect the problem of collision crossbeam assembly assembling difficulty, this connection mode can improve the torsional stiffness of body framwork effectively, is conducive to improve the load-carrying capacity of vehicle body; Further, by with the profile of the zone of stepping down of rear end panel 3 left and right sides bottoms (namely the installation region of collision crossbeam assembly is protected in the back) along back base plate body 1 matched edges excision, make that the bottom profiled of rear end panel 3 is suitable near the edge of rear end panel 3 with back base plate body 1, reach the minimizing tare, reduce the purpose of oil consumption.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the front elevation of rear end panel among the present invention.
Fig. 2 is scheme drawing of the present invention, illustrates among the figure that rear end panel and back base plate body, longeron assembly, back guarantor collide the matching relationship of crossbeam assembly.
The specific embodiment
Embodiment, see also Fig. 1 to 2, a kind of automobile rear end panel and adjacent elements thereof connect combination, comprise back base plate body 1, be arranged on the longeron assembly 2 of base plate body 1 left and right sides, back, rear end panel 3 with back base plate body 1 overlap joint, and be arranged on rear end panel 3 outsides and the back guarantor that matches with longeron assembly 2 collides crossbeam assembly 4, this back is protected collision crossbeam assembly 4 and directly is connected with longeron assembly 2, and the left and right sides bottom of this rear end panel 3 is provided with the zone of stepping down that back guarantor's collision crossbeam assembly 4 and longeron assembly 2 are directly cooperated.
In order to reduce tare, reduce oil consumption, the bottom profiled of rear end panel 3 is suitable, concrete near the edge of rear end panel 3 with back base plate body 1, rear end panel 3 left and right side bottom profiled are along back base plate body 1 matched edges excision, and middle bottom profiled overlaps with back base plate body 1.
Preferably, longeron assembly 2 is provided with the one group of bolt 5 that cooperates with back guarantor's collision crossbeam assembly 4 near the end of rear end panel 3; Perhaps longeron assembly 2 and back are protected collision crossbeam assembly 4 and are connected by welding manner.
With rear end panel 3 and back base plate body 1 overlap joint, the back is protected collision crossbeam assembly 4 and directly is connected with longeron assembly 2, and by with the profile of the zone of stepping down of rear end panel 3 left and right sides bottoms (namely the installation region of collision crossbeam assembly is protected in the back) along back base plate body 1 matched edges excision, make that the bottom profiled of rear end panel 3 is suitable near the edge of rear end panel 3 with back base plate body 1.The invention solves existing rear end panel and easily totally weld error, and then cause the back to protect the problem of collision crossbeam assembly assembling difficulty, adopt back guarantor's collision crossbeam assembly and the connection mode that the longeron assembly directly cooperates to improve the torsional stiffness of body framwork effectively simultaneously, be conducive to improve the load-carrying capacity of vehicle body, reach the minimizing tare, reduce the purpose of oil consumption.
