Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a spare air intake structure for a vehicle. Background Art

[0002] In the current diversified automotive environment, hybrid and extended-range models have improved their aerodynamic performance and energy efficiency by reducing the opening of the air intake grille. However, when driving on snowy days, this design makes the air intake more susceptible to snowflakes than traditional fuel vehicles. In addition, the cabin temperature is generally low, and it is more difficult for snow to melt by itself. Once unmelted snow accumulates in the air intake or inside the air filter, it will directly lead to obstruction of the air intake channel and air circulation. This will not only increase the workload of the air filter element, resulting in a decrease in its filtration efficiency and an increase in resistance, but also directly affect the oxygen supply required for engine combustion. As the intake resistance continues to rise, the power performance of the entire vehicle will be seriously affected. In extreme cases, if the intake obstruction reaches a certain level, the engine will face the risk of stalling due to lack of oxygen, posing a serious threat to driving safety. Utility Model Content

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] A spare air intake structure for a vehicle, such as Figures 1 to 6 As shown, it includes an air filter 1 , on which a main air inlet 2 , a spare air inlet 3 and an air outlet 4 are arranged, and the main air inlet 2 and the spare air inlet 3 are both connected to the air outlet 4 .

[0025] In the present embodiment, the standby air inlet 3 is arranged at the bottom of the air filter 1 , and the position of the standby air inlet 3 is not easily affected by snow accumulation, and the standby air inlet 3 is not easily blocked.

[0026] A control component 5 for controlling the opening or closing of the backup air inlet 3 is provided in the air filter 1 . When the main air inlet 2 is blocked and the internal negative pressure of the air filter 1 increases, the control component 5 opens the backup air inlet 3 .

[0027] Preferably, the control component 5 includes an end cover 51, a spring 52 and a sealing cover 53. The end cover 51 is installed in the air filter 1, the sealing cover 53 is slidably set in the air filter 1, the spring 52 is set between the end cover 51 and the sealing cover 53, and the sealing cover 53 is used to seal the spare air inlet 3. The sealing cover 53 can be close to or away from the spare air inlet 3.

[0028] An installation column 7 is provided in the air filter 1, and the installation column 7 is coaxially arranged with the spare air inlet 3. A central through hole 8 is opened on the sealing cover 53, and the central through hole 8 is opened along the central axis of the sealing cover 53. The installation column 7 passes through the central through hole 8. The sealing cover 53 is guided by the cooperation of the installation column 7 and the central through hole 8, so that the sealing cover 53 is more stable when sliding, thereby ensuring that the sealing cover 53 effectively covers the spare air inlet 3.

[0029] A convex ring 6 is provided in the air filter 1, and the end face of the sealing cover 53 can cooperate with the end face of the convex ring 6 to seal the spare air inlet 3. The end face of the sealing cover 53 fits with the end face of the convex ring 6 to achieve effective sealing of the spare air inlet 3, thereby preventing impurities such as dust and moisture from entering the air filter 1 through the spare air inlet 3.

[0030] A plurality of reinforcing rib blocks 9 are arranged between the mounting column 7 and the convex ring 6, and the plurality of reinforcing rib blocks 9 divide the spare air inlet 3 into a plurality of air inlet channels 13, and the plurality of air inlet channels 13 are evenly distributed along the circumferential direction. The structural strength and stability of the air inlet can be effectively improved by the plurality of reinforcing rib blocks 9. By dividing the spare air inlet 3 into a plurality of air inlet channels 13, the reinforcing rib blocks 9 not only change the flow path of the airflow, but also make the airflow evenly distributed, which helps to reduce the generation of turbulence and eddy currents and improve the air intake efficiency.

[0031] The end cover 51 is installed at the end of the mounting column 7. Specifically, in the present embodiment, the end cover 51 is installed at the end of the mounting column 7 by means of a screw 12. The screw 12 passes through the end cover 51 and is threadedly connected to the mounting column 7. The screw 12 presses the end cover 51 onto the end of the mounting column 7. The spring 52 is sleeved on the outer side of the mounting column 7. One end of the spring 52 is connected to the end cover 51, and the other end of the spring 52 is connected to the sealing cover 53. The stability of the spring 52 is ensured by means of the mounting column 7.

[0032] A positioning groove 10 is provided on the end cover 51, and a positioning groove 2 11 is provided on the sealing cover 53. One end of the spring 52 is located in the positioning groove 10, and the other end of the spring 52 is located in the positioning groove 2 11. The positioning groove 10 and the positioning groove 2 11 restrict the spring 52, thereby improving the stability of the spring 52 and facilitating the installation of the spring 52.

[0033] It should be noted that after the air intake of the main air inlet 2 is blocked, the gas flow in the air filter 1 is reduced, and the internal negative pressure of the air filter 1 increases. The internal high negative pressure squeezes the spring 52, causing the spring 52 to compress and drive the sealing cover 53 to move away from the spare air inlet 3. At this time, the spare air inlet 3 is in an open state, and external gas enters the air filter 1 through the spare air inlet 3; when the negative pressure state in the air filter 1 is relieved, the elastic restoring force of the spring 52 pushes the sealing cover 53 to move towards the spare air inlet 3 until the end face of the sealing cover 53 fits with the end face of the convex ring 6 and the two cooperate to seal the spare air inlet 3. At this time, the spare air inlet 3 is in a closed state.

[0034] It should be further explained that, by arranging a backup air inlet 3 on the air filter 1, when the main air inlet 2 is blocked, the backup air inlet 3 is opened, and external air enters the air filter 1 through the backup air inlet 3. The opening of the backup air inlet 3 ensures that there is still sufficient air intake when the main air inlet 2 is blocked.

[0035] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
