Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and particularly relates to a spare open-type air intake pipe 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

[0025] An intake pipe 4 is provided on the air filter 1. A positioning flange 18 is provided on the outer side wall of the intake pipe 4. The positioning flange 18 is provided along the circumference of the intake pipe 4. The intake pipe 4 and the positioning flange 18 are integrally formed. An annular groove 19 is provided on the positioning flange 18. A sealing end cover 20 is provided in the annular groove 19. The end face of the sealing end cover 20 abuts against the outer surface of the air filter 1, so that the intake pipe 4 and the air filter 1 are sealed by the sealing end cover 20 to ensure the sealing between the two.

[0026] A limiting block 21 is provided on the outer wall of the intake pipe 4, and a limiting opening 22 is provided on the inner wall of the air filter 1. In the present embodiment, the limiting opening 22 is formed by two protrusions that cooperate with each other at intervals. In the present embodiment, there are two limiting blocks 21 and the two are arranged opposite to each other, there are two limiting openings 22 and they correspond one to one with the limiting blocks 21, the limiting blocks 21 are adapted to the limiting openings 22, the limiting blocks 21 are inserted into the limiting openings 22, and the limiting openings 22 limit the limiting blocks 21, thereby realizing circumferential limitation of the intake pipe 4 to prevent the intake pipe 4 from rotating.

[0027] It should be noted that since the end face of the sealing end cover 20 abuts against the outer surface of the air filter 1, the outer end face of the limit block 21 abuts against the inner wall of the air filter 1, the intake pipe 4 is limited, so that the intake pipe 4 and the air filter 1 remain relatively stable, ensuring the stability of the intake pipe 4 and then ensuring the stability of the overall structure.

[0028] A sealing assembly 5 is rotatably provided on the air intake pipe 4, and the sealing assembly 5 is used to seal the air outlet end of the air intake pipe 4.

The flap 51 is rotatably connected to the air intake pipe 4 via a rotating pin 23, and the sealing sheet 52 is provided on the flap 51. Specifically, a plurality of connecting protrusions 8 are provided on the sealing sheet 52, and a plurality of connecting holes 9 are opened on the flap 51. The plurality of connecting protrusions 8 can be respectively snapped into the plurality of connecting holes 9, and the connecting protrusions 8 are snapped into the connecting holes 9 to ensure the relative stability of the sealing sheet 52 and the flap 51. Moreover, the sealing sheet 52 can be removed from the flap 51 by only using an external force to disengage the connecting protrusions 8 from the connecting holes 9, so as to facilitate the maintenance and replacement of the sealing sheet 52.

[0029] The flap 51 cooperates with the sealing sheet 52 to seal the air outlet end of the air intake pipe 4. It should be noted that the air intake pipe 4 is arranged on the side wall of the air filter 1, and the air outlet end of the air intake pipe 4 is provided with an inclined surface 7. The end surface of the sealing sheet 52 is in contact with the inclined surface 7, thereby effectively sealing the air outlet end of the air intake pipe 4 and preventing external impurities such as dust and moisture from entering the air filter 1 through the air intake pipe 4.

[0030] It should be noted that, by the contact between the inclined surface 7 and the end surface of the sealing sheet 52, the contact area can be increased and the sealing performance can be further enhanced. In addition, the inclination angle of the inclined surface 7 and the gravity of the flip cover 51 and the sealing sheet 52 can guide the flip cover 51 and the sealing sheet 52 to automatically adjust their positions to achieve the best sealing effect and improve the sealing performance.

[0031] The sealing component 5 is magnetically attracted to the air outlet end of the air inlet pipe 4 through the magnetic attraction component 6. The magnetic attraction component 6 includes a magnetic block 1 61 and a magnetic block 2 62. The magnetic block 1 61 is arranged on the air inlet pipe 4, and the magnetic block 2 62 is arranged on the flip cover 51.

[0033] At least two snap-in holes 14 are provided on the inner side wall of the accommodating groove 12, and at least two snap-in blocks 15 are provided on the adsorption block 10, and the two snap-in blocks 15 can be snap-into the two snap-in holes 14 respectively; at least two snap-in holes 16 are provided on the inner side wall of the accommodating groove 2 13, and at least two snap-in blocks 2 17 are provided on the adsorption block 2 11, and the two snap-in blocks 2 17 can be snap-into the two snap-in holes 16 respectively. When the magnetism of the magnetic block 1 61 or the magnetic block 2 62 weakens and needs to be replaced, the maintenance personnel can use external force to make the snap-in block 15 detach from the snap-in hole 14, and the adsorption block 10 and the magnetic block 61 can be removed and replaced at the same time, and the snap-in block 2 17 can be detached from the snap-in hole 2 16 by external force, and the adsorption block 2 11 and the magnetic block 2 62 can be removed and replaced at the same time. The operation is simple and the disassembly and assembly are convenient.

[0034] As another solution, any one of the magnetic block 1 61 and the magnetic block 2 62 can be replaced by magnetic metal.

[0035] When the air inlet 2 is blocked and the internal negative pressure of the air filter 1 increases, the sealing component 5 rotates away from the air outlet end of the air inlet pipe 4. Specifically, under normal conditions, the sealing component 5 is magnetically attracted to the air outlet end of the air inlet pipe 4 by the magnetic attraction component 6, and the sealing component 5 seals the air outlet end of the air inlet pipe 4. When the air inlet 2 is blocked and the internal negative pressure of the air filter 1 increases, the sealing component 5 rotates away from the air outlet end of the air inlet pipe 4 under the action of the negative pressure, and the external air can enter the air filter through the air inlet pipe 4. 1, thereby ensuring that there is still sufficient air intake when the air inlet 2 is blocked; when the negative pressure state in the air filter 1 is relieved, under the action of the gravity of the flip cover 51, the sealing sheet 52, the adsorption block 11 and the magnetic block 62, the flip cover 51 rotates close to the outlet end of the air intake pipe 4, and under the magnetic attraction of the magnetic block 1 61 and the magnetic block 2 62, the end face of the sealing sheet 52 is in contact with the inclined surface 7, and the sealing assembly 5 seals the outlet end of the air intake pipe 4.

[0036] 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.
