Technical Field
The invention relates to the technical field of vehicle parts, in particular to a front fender with a weakening structure and a vehicle, and particularly relates to a front fender capable of absorbing energy through plastic deformation of a front fender body when a low-speed collision occurs in front of the vehicle so as to further avoid damage of a front door of the vehicle and the vehicle.
Background
Fenders are vehicle body outer panels that cover the wheels, and are known for their shape and position as bird wings in older vehicle bodies. The fender has the main functions of preventing sand, stone, slurry and the like rolled up by wheels from splashing to the bottom of a carriage in the running process of a vehicle, and simultaneously meets the appearance shape of the vehicle and provides mounting support for vehicle exterior trimming parts such as bumpers, mud guards, front lamps and the like and accessories thereof.
Because of the greater chance of the front fender being hit and scratched, it is common to employ a separate assembly at present. In this way, the front fender can be easily repaired and replaced even if damaged, thereby minimizing loss. When a low-speed collision occurs in front of the vehicle, damage and deformation of the front fender can further cause damage to the front door of the vehicle, which increases maintenance cost. Therefore, there is a need for a new front fender that can absorb energy in the event of a low speed collision in front of the vehicle, reducing maintenance and replacement costs associated with damaged front doors of the vehicle.

Furthermore, the front lining connecting interface 7 below the reinforcing structure 6 is square, a square connecting hole 8 is distributed in the middle of the front lining connecting interface 7, and two corners at the tail end of the front lining connecting interface 7 are smooth round corners. The front liner connection interface 7 is bent toward the vehicle inside direction to form an angle with the wheel arch connecting portion 2 so as to facilitate installation of the front liner. When the device is installed, as shown in fig. 4, the lining body 9 can be padded below the front lining connecting interface 7, and the front lining connecting interface 7 and the lining body 9 can be connected by passing a screw through the square connecting hole 8.
Preferably, the weakening structure 3 is distributed in a position close to the vehicle head direction so that plastic deformation of the front fender mainly occurs in a region close to the vehicle head and far from the front door of the vehicle when a low-speed collision occurs in front of the vehicle, thereby avoiding damage to the front door of the vehicle.
In another aspect, the present invention also provides a vehicle including a front fender according to an embodiment of the invention.
In summary, the present invention provides a vehicle front fender comprising: a front fender body; and a wheel arch connecting part arranged on the front fender body to be connected with the wheel arch, wherein a plurality of weakening structures are arranged on the wheel arch connecting part. When a low-speed collision occurs in front of a vehicle, the front fender is subjected to plastic deformation due to the weakened structure on the front fender, impact energy is absorbed as early as possible, the front fender is prevented from moving towards the front door of the vehicle and further being damaged, and accordingly maintenance and replacement cost caused by damage to the front door of the vehicle is reduced.
