Abstract
The utility model discloses an automobile door defrosting system consisting of an air inlet sealing ring, an air inlet cover, a ventilating pipe and a defrosting grid. The ventilating pipe and an internal decorative plate are arranged together; the air inlet cover is arranged on the internal decorative plate, and the air inlet sealing ring is pressed between the air inlet cover and the internal decorative plate; and the defrosting grid is also arranged on the internal decorative plate. The automobile door defrosting system is characterized in that the outer side of the middle part of the ventilating pipe adopts a straight line type, the inner side of the middle part of the ventilating pipe adopts a great circle type, and a grid is arranged in the ventilating pipe. The utility model occupies less interior trimming space, is easy to arrange and improves the automobile door; in addition, a test of road in a cold region proves that the automobile door defrosting region can satisfy the rear vision requirement of the driver.
Description
Technical field
This practical up-to-date technology belongs to the technical field of Defroster device for vehicle system, particularly a kind of car door defrost system.
Background technology
The quality of car door defrost system is very important thing for chaufeur, is related to himself and other peoples' safety problem after all, under northern arctic weather, is an acid test to the car door defrost system especially.The main task of car door defrost system is that fog of assembling on the automobile door glass and frost are blown open, satisfies the rearward vision requirement of chaufeur.The form that present domestic truck car door defrost system is arranged on the car door is few, be to be arranged on the instrument carrier panel mostly, it is little that reason is exactly the vehicle door interior trim inner space, difficult arrangement, if the design of defrost system correlated parts is unreasonable, as shown in Figures 2 and 3, defrosting effect is with regard to the requirement of out of reach rearward vision, it for chaufeur drives a car breakneck thing, therefore in order to improve area and the height that car door defrosts, the car door defrost system is optimized design and improvement, and the defrost system after the improvement not only will satisfy the problems referred to above, but also has improved the speed of car door defrosting.
Summary of the invention
At the said structure defect situation, the utility model purpose provides a kind of car door defrost system.
The technical solution of the utility model is achieved in that
The utility model car door defrost system, form by ventilation inlet seal ring, air intake mouth mask, breather pipe and defroster grill, breather pipe and trim panel are installed together, the air intake mouth mask is installed on the trim panel, and the ventilation inlet seal ring is pressed between it and the trim panel, and defroster grill also is mounted on the trim panel, it is characterized by: the outside, breather pipe middle part is linear pattern, the inboard is the great circle camber, and barrier is installed in the breather pipe.
The utility model structure interior trim space is occupied little, is easy to arrange, has improved the car door defrosting effect, and proves by cold district road operation test, and the rearward vision requirement of chaufeur is satisfied in car door defrosting zone.

Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The utility model car door defrost system, form by ventilation inlet seal ring 1, air intake mouth mask 2, breather pipe 3 and defroster grill 4, breather pipe 3 is installed together with trim panel, air intake mouth mask 2 is connected on the trim panel, and ventilation inlet seal ring 1 is pressed between it and the trim panel, and defroster grill 4 also is to be connected on the trim panel, it is characterized by: the outside, middle part of breather pipe 3 is linear pattern, the inboard is the great circle camber, and barrier 5 is installed in the breather pipe.
Embodiment:
From Fig. 2, as can be known shown in Figure 4, air intake mouth mask 2 vertical grids of the present utility model are two, horizontal grid is four, and it is the effect of minimizing wind loss and initial stage air intake being played guiding that certain angle, such main purpose are arranged when laterally the grid number is installed with vertical grid.
From Fig. 3 and as can be known shown in Figure 5, vent window A place size has increased 5mm, has increased air-admitting surface like this; The B place of breather pipe 3 has increased arc radius, and it is more smooth and easy that warm braw is passed through; Increased barrier 5 at the breather pipe middle part, made the distribution of Out1, Out2 air quantity more be tending towards rationalizing.Improve the back digital-to-analogue and carried out the measurement of CFD analysis and actual air output, the result is as follows:
Table (1)
| Air quantity (m3/h) | ||
| In | 152.91 | |
| Out1 | 87.25 | 57％ |
| Out2 | 65.66 | 43％ |
It is more reasonable by the breather pipe of table (1) after improving as can be seen air quantity to be distributed, and the also increase to some extent of the air quantity of air outlet Out1, helps satisfying the requirement of rearward vision.
By Fig. 6 and as can be seen shown in Figure 7, Fig. 6 position has the defroster grill structure now, and variation has also taken place the direction of defroster grill from Fig. 7, and the direction of arrow is exactly the direction of grid, simultaneously the width of grid is diminished; Can change the direction and the wind speed of air-out by such improvement, thereby satisfy the requirement of rearward vision, and highly increase can strengthen defrosting barrier guidance quality, is beneficial to the car door defrosting.
Principle of work: distribute the air quantity of coming to pass through air intake mouth mask 2 to breather pipe 3 by air-conditioning, the inner structure of breather pipe 3 is distributed rationalization back arrival defroster grill 4 as far as possible to air quantity, and defroster grill is because the wind speed of the structure raising air outlet of itself then.
Claims (2)
1, car door defrost system, form by ventilation inlet seal ring (1), air intake mouth mask (2), breather pipe (3) and defroster grill (4), breather pipe and trim panel are installed together, air intake mouth mask (2) is installed on the trim panel, and ventilation inlet seal ring (1) is pressed between it and the trim panel, and defroster grill (4) also is mounted on the trim panel, it is characterized by: the outside, breather pipe (3) middle part is linear pattern, the inboard is the great circle camber, and barrier (5) is installed in the breather pipe (3).
2, car door defrost system according to claim 1 is characterized by: vertical grid of described air intake mouth mask (2) is two, and laterally grid is four, and certain angle is arranged when laterally the grid number is installed with vertical grid.
