The invention discloses a car rear threshold assembly, comprising a rear threshold inner plate, a rear threshold lower support plate, a rear threshold guide rail mounting plate, a rear threshold reinforcing plate and a rear threshold inner plate sealing plate. The rear threshold inner plate and the rear threshold lower support plate are positioned below the rear threshold guide rail mounting plate and form a first cavity together with the rear threshold guide rail mounting plate; the rear threshold guide rail mounting plate is provided with a first end and a second end opposite to the first end; the first end faces to the direction of the head of the car and the second end is connected to the rear threshold inner plate sealing plate; the rear threshold reinforcing plate is arranged onto the rear threshold guide rail mounting plate and close to the second end; the rear threshold reinforcing plate, the rear threshold guide rail mounting plate, the rear threshold inner plate, the rear threshold inner plate sealing plate and a floor define a second cavity. The car rear threshold assembly is high in overall structure strength, capable of fully absorbing collision energy generated in the process of side impact, and can efficiently transfer and disperse various kinds of loads from the inside and outside of the car, so that the safety of the car is improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile rear door sill assembly. Background technique [0002] MPV (Multi-Purpose Vehicles) is a car that combines the large passenger space of a station wagon, the comfort of a car and the functions of a van. MPV cars generally have a hatchback structure. The front compartment is the engine compartment, and the rear compartment is the passenger space and luggage space. The rear compartment can be arranged with seats for 5-8 people. The seat configuration generally adopts two to three rows. The layout is flexible, all can be folded or laid down, and some can be moved back and forth, left and right, or even rotated, which gives it great flexibility in its internal structure. [0003] The existing MPV car layout is based on the car structure, which is produced on the car platform, and generally directly adopts the frame structure of the car. The frame structure is gener...
