Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to an automobile air-conditioning air intake device capable of adjusting the air volume distribution ratio. Background Art

[0002] In the design and development of modern automobile air-conditioning systems, improving the comfort of the passenger compartment has become one of the important goals. As people's requirements for automobile comfort continue to increase, higher requirements are also placed on the air volume control and distribution of the air-conditioning system.

[0003] Traditional automobile air-conditioning air intake devices usually adopt a fixed air volume distribution mode, which cannot be flexibly adjusted according to the actual needs of passengers and changes in the external environment. When the car is running at high speed, the wind pressure will be too high, resulting in the fresh air directly convecting into the cabin without passing through the blower in the external circulation mode. This will have a great impact on the heating and cooling efficiency of the passenger compartment. This is also a criticism of most current automobile air-conditioning products, and most air-conditioning box products cannot meet the client's arbitrary proportion adjustment of the fresh air and external circulation air volume under the calibration condition. In response to the above two shortcomings, this design has invented an air intake system that can prevent the fresh air and circulating air from intertwining in the automobile air-conditioning box, and can freely adjust the intake ratio of the two air volumes through the opening size of the damper, which not only meets the thermal efficiency requirements, but also meets the customer's calibration requirements.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6 The utility model provides a technical solution: an automobile air-conditioning air intake device with adjustable air volume distribution ratio, the automobile air-conditioning air intake device with adjustable air volume distribution ratio comprises an air intake box shell 1, a fresh air damper 2, an anti-cross-wind damper 3, a circulating air damper 4, a circulating air intake sealing sponge 5, a baffle 6, a fresh air intake sponge 7 and a circulating air intake channel 8. The air intake box shell 1 is provided with a fresh air damper 2, and the fresh air damper 2 can be made into three forms: a bowl-shaped door, a butterfly door and a flag door. The front side of the fresh air damper 2 is provided with an anti-cross-wind damper 3, and independent cavities are formed on both sides of the anti-cross-wind damper 3. The anti-cross-wind damper 3 has two forms: a flag door and a butterfly door. In order to achieve independent adjustment without cross-wind between fresh air and circulating air, the anti-cross-wind damper 3 is carefully designed inside the air intake box shell 1. When the damper 3 is closed to the baffle 6, its two sides are effectively separated into independent cavities, thereby achieving independent control of fresh air and circulating air, allowing the two to be mixed in different proportions.

[0025] A circulating air door 4 is arranged on the right side of the anti-cross-draft damper 3. The circulating air door 4 can be made into three forms: a bowl-shaped door, a butterfly door and a flag door. The circulating air door 4 is designed into three possible forms according to the space: a bowl-shaped door, a butterfly door and a flag door to adapt to different air flow requirements. Similarly, the anti-cross-draft damper 3 and the fresh air damper 2 are also designed in two forms: a flag door and a butterfly door to enhance the flexibility and efficiency of the system.

[0026] A circulating air intake sealing sponge 5 is provided at the front end of the air inlet box shell 1, a baffle 6 is provided on the left side of the anti-cross-wind damper 3, a fresh air intake sponge 7 is provided at the upper end of the air inlet box shell 1, and a circulating air intake channel 8 is provided inside the circulating air damper 4. In order to maximize the air intake area, the circulating air damper adopts a bowl-shaped design, and a circulating air intake channel 8 is specifically provided on the shell 1 to ensure sufficient air intake flow area. Through the precise coordination between the fresh air damper 2, the anti-cross-wind damper 3 and the circulating air damper 4, the system can flexibly realize three air intake modes: a fresh air mode, a full circulation air mode and a free proportional adjustment mode of fresh air and circulating air.

[0027] Working principle: On the whole vehicle, the fresh air intake sealing sponge 7 will be sealed with the front panel metal (hole) of the car to ensure that the fresh air intake outside the car will not be mixed with the outside of the air conditioner box. In order to ensure that there is no cross-flow between the fresh air and the circulating air, an anti-cross-flow damper 3 is specially designed inside the air inlet box shell 1 to ensure that when 3 is closed to the baffle 6, independent cavities are formed on both sides of the anti-cross-flow damper 3. At this time, the fresh air and the circulating air can be adjusted independently to achieve different air intake ratios between the two. If space permits, the circulating damper 4 can be made into three forms: bowl-shaped door, butterfly-shaped door, etc. Butterfly door, flag door, anti-cross-flow damper 3 has two forms: flag door, butterfly door, fresh air damper 2 can be made into three forms: bowl-shaped door, butterfly door, flag door, and in order to increase the air intake area, a "bowl-shaped" circulation damper is used, and the circulating air intake channel 8 is specially targeted on the shell 1 to ensure sufficient air intake flow area. Through the coordinated opening between the fresh air damper 2, the anti-cross-flow damper 3 and the circulating damper 4, the following three air intake ratio adjustment modes can be achieved: fresh air mode, full circulation air mode, fresh air and circulation air free ratio adjustment mode, such as Figure 6 In the proportional adjustment mode, this design can ensure that there is almost no cross-flow between the fresh air and the circulating air regardless of the vehicle speed.
