Detailed description of the invention
Below in conjunction with specific embodiment, a kind of vehicle body tumble mechanism of the present invention is carried out
Further illustrate.
As Figure 1-3, a kind of vehicle body tumble mechanism, including A post, B post, C
Post and sky window assembly, the bottom of described A post is provided with A post lower reinforcing plate 2, described
The top of A post is provided with A post upper reinforcing plate 1, described A post upper reinforcing plate 1 and institute
The front end stating day window assembly is fixed, and described B post top is provided with B column reinforcement plate 3,
The rear end of the front end of described B column reinforcement plate 3 and described A post upper reinforcing plate 1 is fixed,
Described B column reinforcement plate 3 top sets in the position near window assembly rear end, described sky
Having an extension board 12, the rear end of described extension board 12 and described sky window assembly is fixed, institute
State C post and be provided with C column reinforcement plate 4, described C column reinforcement plate 4 and the top of roof
Beam 7 is fixed.So, A post is arranged and add under A post upper reinforcing plate 1 and A post
Strong plate 2 increases the strength and stiffness of A post, arranges B column reinforcement plate on B post
3 strength and stiffness increasing B post, reduce A post and B in roll procedure
Cylindricality variable, and ensure that the safety of front passenger in car, improve car load
Safety coefficient.It addition, the top of B column reinforcement plate 3 is provided with extension board 12, pass through
Extension board 12 and sky window assembly overlap joint, the setting of extension board 12 adds B post and adds
Strong plate 3 and the coupling stiffness of sky window assembly.And, A post upper reinforcing plate 1 and B
Column reinforcement plate 3 respectively with sky window assembly before and after end fixing, so shape on car body
Become overall firm framework so that overall structure rigidity is bigger, and then reduces
Car body deformation in rolling, it is also possible to A post in roll procedure and B post are subject to
Impulsive force to sky window assembly and car load other parts transmit, decrease and climb over
During A post and B cylindricality variable.Meanwhile, C column reinforcement plate 4 and the top of roof
Beam 7 is fixed, and also increases the rigidity of rear vehicle, reduces car body in rolling
The deformation at rear portion, and ensure that the safety of back occupant in car.

On the basis of case, may is that the front end of described B column reinforcement plate 3 and described A post
The rear end of upper reinforcing plate 1 is fixed by bonding and solder bond at lap position 11.
So, using welding and adhesive bond to fix at lap position 11, fixation can
Lean on, and, it is to avoid at lap position 11 only by being welded and fixed, welding position mistake
Close and the problem that causes not prison welding.Further preferred technical scheme may is that
The two ends of described lap position 11 are provided with solder joint 9, the centre of described lap position 11
It is provided with glue-applying point 10.So, middle employing is adhesively fixed, and two ends use welding
Fixing, both sides welding is in separate location, it is to avoid welding position is overstocked and causes
The problem of not prison welding.And, centre is adhesively fixed, and laminating is tight, firmly
Reliably, improve degree of cooperation, reduce laminating gap.Further preferred is long-pending
Water scheme is it may also is that described glue-applying point 10 at least three, each described gluing
Point 10 is provided with structure glue.So, multiple glue-applying points 10 are so that overlap position
The fixing of middle part putting 11 more closely reduces fixed interval (FI), and, structure glue
Intensity is high, can bear bigger load, and ageing-resistant, endurance, corrosion-resistant.
Seeing accompanying drawing 1-3, a kind of vehicle body tumble mechanism of the present invention is above-mentioned technical side
On the basis of case, may is that described A post is the cavity of square sectional.So,
The cavity of A post changes square into, is beneficial to carrying axial load and opposing axial deformation.
Seeing accompanying drawing 1-3, a kind of vehicle body tumble mechanism of the present invention is above-mentioned technical side
On the basis of case, may is that and add under described A post upper reinforcing plate 1 and described A post
