Description

Automobile front cover with deformation area and vulnerable object protection method Technical Field The invention relates to the technical field of vehicle sheet metal parts, in particular to an automobile front cover with a deformation area and a vulnerable object protection method. Background The vehicle bonnet covers on the engine, plays the effect of protection and shielding to the engine, and among the prior art, the bonnet can form the visual field blind area to the shielding of driver's sight part, and the driver probably is because the situation accuracy judgement of visual field blind area, and then causes traffic accident. Disclosure of Invention The invention aims to overcome the defects of the prior art and provides an automobile front cover with a deformation area and a method for protecting a damaged object. The invention discloses an automobile front cover with a deformation area, wherein the front cover is arranged at the front part of a cab, and the structure of the front cover comprises the following components: A first cover member that covers the vehicle body in such a manner that a unit chamber can be opened and closed; A display unit having a display surface disposed on a first surface of the first cover member, the first surface being a surface facing away from a side adjacent to the unit chamber; An image transmission unit which transmits a picture of the monitoring area in front of the front cover to the display unit; The observation area of the front windshield of the cab comprises a display unit, and the monitoring area at least comprises an area right in front of the front cover of the automobile. The material of the first cover member may be a metal material or a carbon fiber material, which may completely cover the unit cells or partially cover the unit cells, and the first cover member may be deformed to partially absorb energy, which is not limited in more detail, the first cover member in the invention can be arranged in a mode of being high on the side close to the cab and low on the side far from the cab so as to improve the safety of the automobile and reduce the injury degree of pedestrian collision, the position of the head area (bumper area) is arranged low, and the collision point can be lowered to the lower limb area of most pedestrians. In addition, pedestrian can fall on the first lid member in order after being hit, and after the first lid member rear portion (be close to cab one end) is raised, the space between first lid member and the unit room grow, and first lid member can take place elastic deformation, can absorb energy through the deformation better, reduces pedestrian's injury. Preferably, the display unit is configured to be penetrable by light, the first cover member is correspondingly provided with a light transmission area, wherein the light can be projected to the side, opposite to the first surface, of the first cover member from the side close to the first surface through the display unit, the front cover of the automobile can accidentally bounce due to external force or other principles during driving of the automobile by a driver, and the front windshield is covered, and is also covered by the display unit, in this situation, the display unit can close the display of images, and the driver can observe the environment in front of the automobile body through the display unit to make emergency response. Preferably, the first cover member has a first opening disposed thereon, and the display unit is disposed at a position of the first opening, a display area of the display unit covering the first opening; the display unit comprises a frame body and a display panel inlaid in the frame body, and the display area of the display panel is obliquely arranged towards the direction of the cab; A gap is formed between the display panel and the inner cavity of the frame body, a through hole is formed in the first surface of the frame body, so that the gap is formed between the display panel and the inner cavity of the frame body and is communicated with the outside, and the first surface is one side, far away from the cab, of the frame body. For the first opening on the first cover member in the present invention, which is used for preventing the situation that the front cover is accidentally tilted, a driver can observe the area in front of the vehicle body through the display unit and the first opening, the height of the first cover member gradually decreases from the cockpit to the bumper, the planar arrangement is inconvenient for the driver to observe the image of the display panel, in order to observe the display unit through the cab, the display area of the display panel is obliquely arranged towards the direction of the cab, so that the observation of the image is convenient for the better visual angle, the heat generated at the back of the display panel is serious, the generated heat is conducted to the space between the display panel and the inner c
