Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The body structure 100 according to this utility model embodiment is described in detail referring to Fig. 1, as it is shown in figure 1, vehicle body knot
Structure 100 includes vehicle-body outer panel 1, body stiffening panel 2 and body inner panel 3, and body stiffening panel 2 is positioned at vehicle-body outer panel 1 and body inner panel 3
Between, body stiffening panel 2 at least partly the most spaced apart with vehicle-body outer panel 1 to form cavity 4, it is filled with double-component in cavity 4 poly-
Urethane, and formed dual-component polyurethane polyreaction occur in cavity 4.
It is understood that due to the existence of cavity 4, vehicle-body outer panel 1 is prone to concave, double by filling in cavity 4
Component polyurethane, can fill this cavity 4, the dent resistance of vehicle-body outer panel 1 is substantially improved, and forms the raw material of dual-component polyurethane
For liquid, good fluidity, can be with the less cavity 4 of injected slurry volume, after the raw material forming dual-component polyurethane injects cavity 4,
In cavity 4, the raw polyreaction of hybrid concurrency, rapid setting expansion, fill this cavity 4.
Such as dual-component polyurethane can be polymerized with amine polymer by epoxy resin, and epoxy resin and amine polymer are each
From independently depositing in container, and being liquid, after being packed into cavity 4, epoxy resin and amine polymer are mutually mixed, often
Solid-state is quickly formed by semiliquid semi-solid state under temperature.The time of injection ring epoxy resins and amine polymer can be according to cavity 4
The speed of expansion of volume, charge velocity and dual-component polyurethane calculate.
Body structure 100 according to this utility model embodiment, by use dual-component polyurethane fill vehicle-body outer panel 1 with
Cavity 4 between body stiffening panel 2, can be substantially improved the dent resistance of body structure 100, particularly can promote large area metal plate
The dent resistance of gold part, the lightweight level of body structure 100 is high, it is also possible to plays the effect of vibration and noise reducing, and is applicable to volume
Less cavity 4.
In preferred embodiments more of the present utility model, with reference to Fig. 1, body stiffening panel 2 can be provided with reinforcing plate
Via 21, reinforcing plate via 21 can connect with cavity 4, and body inner panel 3 can be provided with inner panel via 31, and inner panel via 31 can
To connect with reinforcing plate via 21, such as inner panel via 31 so can be used for injecting double with reinforcing plate via 21 just to setting
The glue rifle of the raw material of component polyurethane can stretch into by the inner panel via 31 from body inner panel 3, and after filling completes, solidification
Dual-component polyurethane can be with automatic plugging reinforcing plate via 21 and inner panel via 31.
Alternatively, reinforcing plate via 21 may be located at the top of cavity 4, so, it is simple to makes dual-component polyurethane as far as possible
Ground is full of cavity 4.
Preferably, inner panel via 31 and reinforcing plate via 21 one_to_one corresponding, the corresponding at least two inner panel via of each cavity 4
31 and two reinforcing plate vias 21, each two inner panel via 31 and reinforcing plate via 21 are formed as one group, and each cavity 4 correspondence is many
Group inner panel via 31 and reinforcing plate via 21, often group inner panel via 31 and reinforcing plate via 21 can corresponding one group of glue rifle, for
The cavity 4 that volume is bigger, can prevent former by injecting raw material from many group inner panel vias 31 and reinforcing plate via 21 to cavity 4
The mixing cured too fast of material causes the compactedness of subregion not, certainly, for the cavity 4 that volume is bigger, it is also possible to directly
Promote the charge velocity of glue rifle.
It should be noted that inner panel via 31 and reinforcing plate via 21 are preformed hole when designing vehicle body, and in general assembly
Workshop or application finishing operation just inject formation dual-component polyurethane by inner panel via 31 and reinforcing plate via 21 to cavity 4
Raw material.
In preferred embodiments more of the present utility model, vehicle-body outer panel 1 can be C post outside plate, and body stiffening panel 2 can
Think C column reinforcement plate, body inner panel 3 can be C post inner panel, i.e. body structure 100 can be C post, the dent resistance of such C post
Height, certainly, body structure 100 can also be the miscellaneous part on vehicle body, such as A post, B post etc..
In sum, according to the body structure 100 of this utility model embodiment, by using dual-component polyurethane to fill car
Cavity 4 between body outside plate 1 and body stiffening panel 2, can be substantially improved dent resistance and the body structure 100 of body structure 100
Lightweight level, it is also possible to playing the effect of vibration and noise reducing, and filling process is simple, charging efficiency is high.
Vehicle according to this utility model embodiment is described below.
As it is shown in figure 1, be provided with the body structure of any of the above-described kind of embodiment according to the vehicle of this utility model embodiment
100.The vehicle of this utility model embodiment, the dent resistance of vehicle body is good, and lightweight level is high, and vibration and noise reducing performance is excellent.
