Description

Double-layer hollowed-out automobile front windshield lower decorative plate structure and automobile body Technical Field The invention relates to the technical field of automobile exterior trim, in particular to a double-layer hollowed-out automobile front windshield lower decorative plate structure and an automobile body. Background Because the front cabin needs to integrate a plurality of parts such as an engine, a gearbox, a controller, an electric box, a condenser, an air conditioning system and the like, the arrangement space of the lower decorative plate of the front windshield is greatly compressed. In addition, the intelligent and comfort requirements of users on the automobile air conditioning system are continuously improved, for example, after a vehicle is parked for a period of time, the air conditioner can be automatically started when a driver approaches to the vehicle, fresh air ventilation is performed in the vehicle, and strict requirements on the air intake of the air conditioner are set. The ventilation function is only activated when the person is on the main driving side and is sufficiently close to the vehicle, and the effective duration of the air conditioner for starting ventilation is not longer than 5 seconds at the activation logic. Therefore, the difficulty of fully replacing the air in the vehicle is extremely high in a very short time, the running power of the air conditioner can be generally increased, the section of the air inlet hole and the section of the air duct are enlarged as much as possible within the design allowable range to optimize the ventilation effect, and the installation space of peripheral parts such as a lower decorative plate of a front windshield is further extruded. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide a double-layer hollowed-out automobile front windshield lower decorative plate structure and an automobile body, which can meet the air inlet requirement of an air conditioner under the condition of smaller space, meet the five-star collision requirement of European Union, and avoid the problem that front cabin waste gas enters the air conditioner to pollute indoor air.
