Abstract
The invention provides a structure of a C column lower joint. The C column lower joint comprises a doorstill outer reinforcing plate, a front protection plate, an installation belt reinforcing plate, a back wheel casing front connecting plate and a back wheel casing outer plate; the back wheel casing outer plate is connected with the back wheel casing front connecting plate, the back wheel casing front connecting plate is connected with the doorstill outer reinforcing plate and the front protection plate separately, and the installation belt reinforcing plate is connected with the front protection plate and the back wheel casing front connecting plate separately. The structure of the C column lower joint has the advantages that due to the fact that a traditional back wheel casing outer plate is arranged separately and separated into the back wheel casing front connecting plate and the back wheel casing outer plate, the connecting strength is improved, and the material utilization rate is increased.
Description
Technical field
The present invention relates to body of a motor car, more particularly, to one of body of a motor car c post lower contact structure.
Background technology
C post lower contact is one of important joint of door frame on rear side of traditional mpv, and its structure quality directly influences rear side
The intensity in the rigidity of doorframe and c post lower contact dog-leg region, safe pulling force statutes test, the even rigidity of car load and car load are durable
Property.Traditional c post lower contact is as shown in figure 1, comprise rear wheel cover outer plate 104, threshold external reinforcing plate for car 101, apron plate 102, seat belt
Reinforcing plate 103.
Its shortcoming is mainly:
1) rear wheel cover outer plate 104 and doorframe waling are not attached to, and structural strength is weak, poor durability；
2) rear wheel cover outer plate 104 integration is higher to forming parts requirement and stock utilization is low, with fixing point under seat belt
Bonding strength is weak；
3) total part relatedness is weak, and material selects limitation larger, is unfavorable for improving the strength of joint changing region.
Content of the invention
In order to solve the problems of the prior art, the invention provides a kind of c post lower contact structure.
The invention provides a kind of c post lower contact structure, including threshold external reinforcing plate for car, apron plate, install band reinforcing plate, after
Connecting plate and rear wheel cover outer plate before wheel cover, wherein, described rear wheel cover outer plate is connected with described front connection board of back wheel cover, described trailing wheel
Before cover, connecting plate is connected with described threshold external reinforcing plate for car, apron plate respectively, described install band reinforcing plate respectively with described apron plate,
Front connection board of back wheel cover connects.
As a further improvement on the present invention, described apron plate is provided with welding via.
As a further improvement on the present invention, described threshold external reinforcing plate for car insertion is to described front connection board of back wheel cover.
The invention has the beneficial effects as follows: by such scheme, traditional rear wheel cover outer plate is carried out piecemeal setting, after being divided into
Before wheel cover, connecting plate and rear wheel cover outer plate, improve bonding strength, improve stock utilization.
Brief description
Fig. 1 is the schematic diagram of traditional c post lower contact.
Fig. 2 is a kind of schematic diagram of present invention c post lower contact structure.
Fig. 3 is the profile a-a of Fig. 2.
Specific embodiment
The present invention is further described for explanation and specific embodiment below in conjunction with the accompanying drawings.
Drawing reference numeral in Fig. 2 to Fig. 3 is: threshold external reinforcing plate for car 1；Apron plate 2；Band reinforcing plate 3 is installed；Connect before rear wheel cover
Fishplate bar 4；Rear wheel cover outer plate 5；Welding via 6.
As shown in Figure 2 to Figure 3, a kind of c post lower contact structure, including threshold external reinforcing plate for car 1, apron plate 2, installs band reinforcement
Plate 3, front connection board of back wheel cover 4 and rear wheel cover outer plate 5, wherein, described rear wheel cover outer plate 5 is with described front connection board of back wheel cover 1 even
Connect, described front connection board of back wheel cover 1 is connected with described threshold external reinforcing plate for car 1, apron plate 2 respectively, described installation carries 3 points of reinforcing plate
It is not connected with described apron plate 2, front connection board of back wheel cover 4.
As shown in Figure 2 to Figure 3, described apron plate 2 is provided with welding via 6.
As shown in Figure 2 to Figure 3, the insertion of described threshold external reinforcing plate for car 1 is to described front connection board of back wheel cover 4.
A kind of c post lower contact structure that the present invention provides has the following characteristics that
1) threshold external reinforcing plate for car 1 penetrates into wheel arch area always, improves structure bonding strength, solves the heavily stressed of dog-leg region and asks
Topic, improves body torsional rigdity；
2) traditional rear wheel cover outer plate is carried out bulk-breaking, be divided into front connection board of back wheel cover 4 and rear wheel cover outer plate 5, improve material use
Rate, the front connection board of back wheel cover 4 of front end improves part thickness, improves fixing point structural strength under seat belt；
3) welding via 6 design of apron plate 2 ensure that welding operability.
4) joint part overall relevance is strong, improves, by suitable piecemeal, the multiformity that material selects, improves joint strong
Degree is it is ensured that structure can carry the load of rear overhang.
A kind of c post lower contact structure that the present invention provides has the advantages that
1) structural relationship improves, and improves the bonding strength of this joint, solves the heavily stressed problem in dog-leg region, and side-wall outer-plate should
Power declines about 30mpa, takes turns hood panel stress decrease about 40mpa.
2) take turns hood panel block design, while reducing wheel hood panel molding difficulty, improve stock utilization.
Above content is to further describe it is impossible to assert with reference to specific preferred implementation is made for the present invention
Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of present inventive concept, some simple deduction or replace can also be made, all should be considered as belonging to the present invention's
Protection domain.
