Technical Field

[0001] The utility model relates to the technical field of automobile bodies, in particular to an automobile heater pressure chamber plate assembly and an automobile. Background Art

[0002] The pressure chamber plate assembly of the automobile heater is an important part of the welded body. The pressure chamber plate assembly of the automobile heater is located at the bottom of the front windshield and is connected to the left and right side assemblies and the left and right front wheel hub assembly by welding. The pressure chamber plate assembly of the automobile heater is an important component for isolating the engine compartment and the passenger compartment. It is the main drainage structure at the front of the vehicle body, providing installation support for the front windshield and providing installation points for wipers, wiring harnesses, CCB, etc. The performance indicators met by the pressure chamber plate assembly of the automobile heater mainly include: pedestrian protection, vehicle torsional stiffness, and stiffness of wiper installation points. The functional requirements of the pressure chamber plate assembly of the automobile heater are mainly: isolating the engine compartment and the passenger compartment to prevent the air conditioning air intake from inhaling a large amount of engine exhaust gas; directing rainwater falling from the front windshield to the wheel hubs on both sides to prevent a large amount of water from entering the engine compartment and causing a short circuit in the wiring harness; providing installation points for wipers, CCB, and wiring harnesses, and meeting the stiffness of the installation points. The main design difficulties of the automobile heater pressure chamber plate assembly are: the heater pressure chamber plate assembly cannot allow the air conditioner to inhale a large amount of water vapor and cause water to enter the passenger compartment while guiding water; the structure needs to be designed with a rat-proof structure to prevent rats from drilling into the air conditioner through the heater pressure chamber plate drain port and the air inlet of the air conditioner to damage it and produce odor, and it is connected with the left and right side panels and the left and right front wheel hub packages to improve the torsional stiffness of the entire vehicle.

[0003] For example, the patent document CN113460172B discloses a heater pressure chamber plate welding assembly and a car, comprising: a heater pressure chamber plate arranged in a U shape; a front windshield reinforcement member, which is assembled and connected to one side of the heater pressure chamber plate and extends obliquely downward into the U-shaped cavity of the heater pressure chamber plate; a pressure chamber plate reinforcement beam, which is assembled on the other side of the heater pressure chamber plate, and the pressure chamber plate reinforcement beam and the inner wall of the heater pressure chamber plate form a closed cavity; the heater pressure chamber plate is formed with a dashboard mounting point, and the pressure chamber plate reinforcement beam is formed with a wiper mounting point. However, the torsional stiffness of the whole vehicle still cannot meet the demand well.

[0004] Therefore, it is necessary to develop a new automobile heater pressure chamber plate assembly and automobile. Summary of the invention
