the stamped front hatch cover has high requirements on materials, the materials have good tensile ductility, the inner plates are mostly non-metal layers, and the inner plates and the outer plates are connected in an adhesive manner, so that the high requirements on manufacturing cost and process are provided. In addition, for the new energy electric vehicle, the front cabin cover plate made of metal plates is used, so that the quality of the whole vehicle is increased, and the endurance and other capabilities of the new energy electric vehicle are not improved; although the front deck cover plate made of pure plastic is relatively light and is beneficial to improving the endurance of the electric automobile and the like, the front deck cover plate made of pure plastic has many defects, such as material performance which cannot meet the requirements, easy warping, easy deformation and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide the front cabin cover plate of the electric automobile, which has the advantages of good corrosion resistance, low weight and low cost.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: an electric vehicle front deck cover, comprising:
a front hatch outer panel;
the front hatch cover inner plate is connected with the front hatch cover outer plate;
the lock catch reinforcing plate is arranged on the outer plate of the front hatch cover, and the lock catch is arranged on the lock catch reinforcing plate;
and the stay bar reinforcing plate is arranged on the outer plate of the front hatch cover, and the stay bar is connected with the stay bar reinforcing plate.
The front hatch cover outer plate is made of SMC material; the front hatch cover inner plate is made of LFT materials.
The front hatch cover inner plate is connected with the front hatch cover outer plate in a sticking mode through structural adhesive.
The lock catch reinforcing plate and the stay bar reinforcing plate are connected with the front hatch cover outer plate through self-tapping screws.
One of the above technical solutions has the following advantages or beneficial effects,
1. by adopting the technical scheme, the whole vehicle welding manufacturing process can be completely avoided, welding equipment and welding labor are not required to be invested, and the manufacturing cost of manufacturers is greatly reduced.
2. The front hatch cover outer plate is made of SMC materials, and the main reasons are as follows: compared with the traditional steel, the SMC material product is lighter by 20-30% under the condition of meeting the strength of the electric automobile, and meets the design requirement of light weight of the whole automobile for the electric automobile; the mechanical property can be still maintained under the high temperature condition; the corrosion resistance is good, and the dent generated after being impacted has the resilience capability, so that the anti-collision device is very suitable for the outer plate of the front hatch cover; the SMC material product can adapt to a steel plate spraying technology, and the production line does not need to be excessively reformed for enterprises. When the SMC is used on the outer plate of the front hatch cover, the functions of other parts of the whole vehicle cannot be influenced.
3. The front hatch cover inner plate is made of LFT materials, and the main reasons are as follows: the cost is lower, the performance is high, the recovery rate is high, the density is low, and the manufacturing cost of manufacturers, the performance required by customers and the light weight of the electric vehicle can be met. It is important to provide that the LFT material as the inner panel is more excellent in impact resistance than the SMC material of the outer panel, and even if the front hatch cover is subjected to a severe impact, the LFT inner panel can minimize the loss by virtue of its excellent properties, and can effectively protect the components in the front hatch, the motor/engine, and the like.
4. Except for the inner plate and the outer plate, the components such as the lock catch reinforcing plate, the stay bar reinforcing plate and the like are made of aluminum alloy materials, so that the problems of failure and falling caused by rusting can be effectively solved.
