Drawings
The contents of the drawings and the reference numbers in the drawings are briefly described as follows:
fig. 1 is a schematic front view of the present invention;
fig. 2 is a schematic top view of the structure shown in fig. 1.
Labeled in the figure as:
1. the structure comprises a front bumper, 2, a lower cross beam, 3, a heat exchanger, 4, a wind shielding structure, 5, a front bumper lower protective plate, 6 and a sealing area.
Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.
Based on the state of the prior art, the utility model provides a structure for achieving the ventilation quantity of a front end cooling module of a vehicle carrying a lower cross beam; this structure can be applied to a vehicle not having a lower cross member.
The structure of the present invention as shown in fig. 1 and 2 is a wind shielding structure for a lower guard plate of a front bumper, and is applied to a front end cooling module of a passenger car; the passenger car is internally provided with a lower cross beam 2; the cooling module comprises a heat exchanger 3, and a neutral position is arranged between a front bumper lower protective plate 5 and the heat exchanger 3.
The heat exchanger 3 is arranged behind the front bumper 1.
In order to solve the problems existing in the prior art and overcome the defects thereof, the invention aims to improve the heat exchange efficiency of the heat exchanger, the utility model discloses the technical scheme who takes is:
as shown in fig. 1 and fig. 2, the wind shielding structure 4 of the front bumper lower guard plate of the present invention is that the front bumper lower guard plate 5 is located at a position below the heat exchanger 3, and a protrusion facing the heat exchanger 3 is provided to form a sealing area 6.
The invention arranges a corresponding wind shielding structure in the profile range of the heat exchanger 3 for the front bumper lower guard plate 5, forcibly introduces the inlet wind into the air inlet of the heat exchanger 3, properly seals the sealing area 6, blocks the wind leakage path and ensures the ventilation volume.
The utility model discloses innovation point, advantage of creating:
1. the structure of a lower protective plate of the front bumper is optimized, and the function of the original wind shield is realized;
2. and a wind shield is omitted, so that the weight of the whole vehicle is reduced, and the cost is reduced.
The utility model is suitable for a required air volume of front end cooling module is ensured to all kinds of passenger cars, all has positive meaning to the cooling of vehicle and air conditioner cooling performance, reduction product weight and manufacturing cost.
The bulge is formed by injection molding or stamping. If the front bumper lower guard plate 5 is made of plastic, the protrusions are formed by injection molding; if the material of the front bumper lower guard plate 5 is a steel plate, the bulge is formed by stamping.
