This invention discloses a vehicle hood assembly and a vehicle. The hood assembly includes: an engine hood, with a structural component below the engine hood; and a buffer bracket, the buffer bracket having a bracket body and a bracket connecting portion, the bracket connecting portion being connected to the engine hood. The bracket body can cooperate with the structural component so that, in the event of a collision with the engine hood, the bracket body can slide longitudinally along the surface of the structural component under the guidance of the structural component. By allowing the bracket body to slide longitudinally along the vehicle when the engine hood collides, this invention increases the longitudinal crumple zone compared to the vertical crumple zone in related technologies, thereby increasing the crumple space and adapting to a novel engine hood design.

This application relates to the field of vehicle component manufacturing technology, and discloses a controller bracket, a front engine compartment assembly, and a vehicle. The controller bracket includes a bracket body and a first connecting portion, which are integrally formed. The first connecting portion is located at a first end of the bracket body along a first direction and is used to connect to the vehicle body. Multiple mounting portions are provided on both sides of the bracket body along a second direction, and these mounting portions are used to mount a first controller or a second controller. This application embodiment can form the controller bracket through integral injection molding, which helps reduce the strength of the controller bracket, increases the crumple zone in the front engine compartment during a vehicle collision, and improves the vehicle's pedestrian protection function. Compared to related technologies, this application embodiment can also reduce the weight of the controller bracket, which is beneficial for vehicle lightweighting; furthermore, it also helps improve production efficiency.

The invention relates to a fairing assembly (2) for a motor vehicle. The fairing assembly (2) forms the underbody of the motor vehicle and comprises a battery support, which is generally flat and extends between two longitudinal members of the motor vehicle, and an intermediate floor (14) integral with the battery support. The intermediate floor (14) has a concave profile (15) such as to form a housing for a high-voltage electric battery of the motor vehicle between said intermediate floor (14) and the battery support. According to the invention, the intermediate floor (14) has, at an outer lateral edge (17), a programmed crumple zone (21) configured to compress in the event of a lateral impact and dissipate energy from said lateral impact.

This utility model discloses an elephant trunk-shaped frame assembly, a front bulkhead assembly, and a vehicle. The elephant trunk-shaped frame assembly includes: a transition structure adapted to connect to an energy-absorbing box and for connecting to the front part of the front bulkhead longitudinal beam; and an elephant trunk-shaped frame body, the front part of which is connected to the transition structure, and the rear part of which is connected to the A-pillar. At least a portion of the elephant trunk-shaped frame body is constructed as a crumple zone, which is constructed to be inclined outward from bottom to top along the front-rear direction. The elephant trunk-shaped frame assembly of this utility model can simultaneously connect the energy-absorbing box to both the front bulkhead longitudinal beam and the elephant trunk-shaped frame body, thereby increasing the transmission path of collision force, improving the reliability of collision force transmission and dissipation, effectively reducing the transmission of collision force into the passenger compartment, improving the vehicle's collision performance and safety, and allowing the crumple zone to simultaneously bend and deform upward and backward to absorb collision force, further reducing the transmission of collision force into the passenger compartment.

A head-up display (HUD) apparatus comprises a housing including a lower case that is open at a top thereof and defines an internal space, and an upper case that corresponds to the lower case to cover the top of the lower case; an aspherical mirror configured to reflect an image emitted from a picture generation unit onto a windshield, and the aspherical mirror being disposed in the lower case; and a crumple zone including an impact absorbing unit configured to be disposed in the housing and to absorb an impact transmitted to the housing, in the event of a vehicle collision.

This invention discloses a chassis assembly and a vehicle having the same, belonging to the field of wheel crumple zone energy absorption technology. The chassis assembly includes a wheel, a frame, and a crash unit assembly. An A-pillar is connected to the frame, and the wheel is connected to the frame. The crash unit assembly is located on the A-pillar and on one side of the wheel in the horizontal direction. The free end of the crash unit assembly is positioned opposite the wheel, and the crash unit assembly is constructed to destroy the wheel. When the chassis assembly collides, the wheel contacts the free end of the crash unit assembly, causing the wheel structure to collapse and absorb energy. Because the crash unit assembly is located on one side of the wheel, it can break the wheel structure upon impact, thus destroying the wheel structure. The destroyed wheel structure can absorb the impact, reducing the impact force on the cab and improving driving safety.

A front body structure in an electric vehicle, by positioning the driving motor as close as possible to the rear of the vehicle, ensures sufficient crumple zone in the longitudinal direction during a collision while suppressing impact loads on the battery during a collision. The front body structure (A) includes: a partition defining the interior space of the passenger compartment; a motor mounting section formed by a portion of the partition extending inwards into the passenger compartment, where at least a portion of the driving motor can be mounted; and a reinforcing member (94) extending from the upper part of the motor mounting section toward the rear of the vehicle, inclined downwards towards the rear of the vehicle. The rear part of the reinforcing member (94) is mounted to the floor panel (70) and the cover (35) of the battery cell (BY).

The utility model provides a front longitudinal beam assembly and a vehicle. The front longitudinal beam assembly comprises a first plate area and a second plate area, and the material strength of the first plate area is smaller than that of the second plate area. The first plate area and the second plate area are arranged in the length direction of the vehicle body, and the first plate area is close to one side of the vehicle head. A first cavity is formed in the first plate area, at least two second cavities are formed in the second plate area, and the second cavities are arranged in the height direction of the vehicle body. The first plate area can serve as a collision energy absorption crushing area, when a vehicle body collides, the first plate area can mainly bear collision deformation energy absorption, a part of collision energy is absorbed firstly, and then the remaining collision energy is transmitted to the second plate area with higher strength, so that the energy absorption efficiency after collision is greatly improved, and higher structural safety is achieved.
