Upper end protrude out to rear wheel casing inner plate top and with rear wheel cover outer plate weld, the C column reinforcement plate and rear wheel casing inner plate add
Strong plate is welded as a whole.
In above scheme, C column reinforcement plate is connect with rear wheel casing inner plate stiffening plate, between C column reinforcement plate and rear wheel casing inner plate
Formed clearly, effectively Path of Force Transfer, guarantee the smooth transmitting of stress, prevent stress raisers, effectively absorb energy.
Entire transmission path constitutes a complete C ring and avoids vehicle body from cracking to improve the torsion stiffness of entire vehicle body, reduces
Vehicle body jolts sense.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2, Fig. 3 are the explosive view of Fig. 1.
Specific embodiment
- Fig. 3 refering to fig. 1, a kind of C column reinforcement plate connection structure, including C column reinforcement plate 10, the upper end of C column reinforcement plate 10 are prolonged
It extends at body side rail, welded on the outside of lower end and rear wheel cover outer plate 20, rear wheel cover outer plate 20 and rear wheel casing inner plate 30 are welded as one
Body, the inside of rear wheel casing inner plate 30 are provided with rear wheel casing inner plate stiffening plate 40, and the upper end of rear wheel casing inner plate stiffening plate 40 protrudes out to
It is simultaneously welded with rear wheel cover outer plate 20, the C column reinforcement plate 10 and rear wheel casing inner plate stiffening plate 40 on the top of rear wheel casing inner plate 30
It is welded as a whole.At 10 upper end to body side rail of C column reinforcement plate, lower end and rear wheel casing inner plate stiffening plate 40 connection, form one
Kind complete, continuous cyclic structure and Path of Force Transfer, i.e., formed between C column reinforcement plate 10 and rear wheel casing inner plate 30 clearly,
Effectively Path of Force Transfer guarantees the smooth transmitting of stress, prevents stress raisers, effectively absorb energy.Entire transmitting road
Diameter constitutes a complete C ring and avoids vehicle body from cracking to improve the torsion stiffness of entire vehicle body, and reduction vehicle body jolts sense.
As a preferred solution of the present invention, the welding surface and rear wheel cover of the C column reinforcement plate 10 and rear wheel cover outer plate 20
The welding surface of inner panel stiffening plate 40 and rear wheel cover outer plate 20 is the two sides plate face of 20 the same area plate body of rear wheel cover outer plate respectively.It changes
A kind of saying is exactly, and rear wheel casing inner plate stiffening plate 40, C column reinforcement plate 10 and is clipped in 20 plate body of rear wheel cover outer plate between the two
Part is welded as a whole, and the welding position of the two and rear wheel cover outer plate 20 is at same position, that is to say, that between the two
It is the equal of being directly connected to.
In order to further enhance the reliability connected between rear wheel casing inner plate stiffening plate 40, C column reinforcement plate 10, outside rear wheel cover
It is provided with missing portion 21 in the middle part of plate 20 and the welding region of rear wheel casing inner plate stiffening plate 40, C column adds in 21 region of missing portion
Strong plate 10 and rear wheel casing inner plate stiffening plate 40 are directly welded as a whole.C column reinforcement plate 10 and rear wheel casing inner plate stiffening plate 40 in this way
It is directly welded as a whole, power is effectively transmitted.
The cavity inside that rear wheel cover outer plate 20 and rear wheel casing inner plate 30 form is provided with rear shock absorber mounting plate 50, described
Rear shock absorber mounting plate 50 and rear wheel casing inner plate stiffening plate 40 are located inside and outside 30 the same area plate body of rear wheel casing inner plate
It two sides and is weldingly fixed on rear wheel casing inner plate 30.It is said differently and is exactly, rear wheel casing inner plate stiffening plate 40, rear shock absorber peace
Loading board 50 and the 30 plate body part of rear wheel casing inner plate being clipped between the two are welded as a whole, although rear wheel casing inner plate is reinforced
Plate 40 and rear shock absorber mounting plate 50 are connected by rear wheel casing inner plate 30, but are between the two the equal of being directly connected to.Also
It is to say, if 30 plate body of rear wheel casing inner plate being clipped between rear wheel casing inner plate stiffening plate 40, rear shock absorber mounting plate 50 is considered as
It is not present, then rear wheel casing inner plate stiffening plate 40, rear shock absorber mounting plate 50 are equivalent to and are directly welded as a whole.Certainly, may be used
To reserve vacancy on rear wheel casing inner plate 30 by the change in technological design, consequently facilitating rear wheel casing inner plate stiffening plate 40, after
Shock absorber mounting board 50 is bonded to each other and is directly welded as a whole, the preferred former scheme of the present invention.
