Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a filter structure for new energy vehicles. Background Art

[0002] The air filter of new energy vehicles is mainly used to filter the air entering the vehicle interior, improve the air quality, and protect the respiratory health of vehicle occupants. It is generally used to filter out pollutants such as dust, pollen, exhaust gas, volatile organic compounds, PM2.5, etc.

[0003] An air filter generally has an air inlet and an air outlet. A filter element is arranged between the air inlet and the air outlet. Since the size of the air inlet is relatively small and the size of the filter element is relatively large, when the air flow moves, the part of the filter element facing the air inlet bears the vast majority of the air flow, which also causes the part of the filter element facing the air inlet to filter the vast majority of pollutants. The utilization rate of the part of the filter element far from the air inlet around is relatively low, resulting in a reduction in the overall effective utilization rate of the filter element and a reduction in the filtration efficiency. Summary of the Utility Model

The aperture diameters of the plurality of first ventilation holes increase in sequence from the direction close to the dirty gas inlet to the direction far from the dirty gas inlet.

[0007] The housing has a first mixing cavity between the dirty gas inlet and the first static dispersion plate;

[0008] And / or the housing has a second mixing cavity between the first static dispersion plate and the first filter element.

Ears are provided at positions corresponding to the stretching groove on the circumferential side of the cover, and the ears are fixed to the threaded cylinders by screws.

[0011] One side of the cover away from the shell body has a mounting portion for fixedly assembling with an external device.

[0012] A first sliding groove is integrally formed on the inner wall of the shell body along the first stretching direction. First long strip portions are integrally formed on both sides of the first static dispersion plate along the first stretching direction, and the first long strip portions are in limiting assembly with the first sliding groove.

[0013] A first support rib is integrally formed on the inner wall of the shell body along the first stretching direction, and the first filter element is in limiting assembly between the first static dispersion plate and the first support rib.

[0014] The filter structure further includes a second static dispersion plate and a second filter element located inside the outer shell. The second static dispersion plate and the second filter element are located between the first filter element and the clean air outlet. The second static dispersion plate is located between the first filter element and the second filter element. The second static dispersion plate is an arc-shaped plate and protrudes towards the dirty gas inlet direction. A plurality of second ventilation holes are formed on the second static dispersion plate, and the diameters of the plurality of second ventilation holes increase in sequence from the direction close to the dirty gas inlet to the direction away from the dirty gas inlet.

[0016] and / or the outer shell has a fourth mixing cavity between the second static dispersion plate and the second filter element;

[0017] and / or the outer shell has a fifth mixing cavity between the second filter element and the clean air outlet.

[0018] Define the length direction of the outer shell as the first stretching direction, and the two ends of the outer shell in the first stretching direction are the front end and the rear end respectively.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Referring to Figures 1 - 3 , a filter structure for a new energy vehicle includes an outer shell 10. The outer shell 10 has a turbid gas inlet 3 and a clean gas outlet 4. A first filter element 6 is provided between the turbid gas inlet 3 and the clean gas outlet 4 inside the outer shell 10. The air flow enters the outer shell through the turbid gas inlet 3, is filtered by the first filter element 6, and then is discharged from the clean gas outlet 4. A first static dispersion plate 7 is provided between the first filter element 6 and the turbid gas inlet 3 inside the outer shell 10. The first static dispersion plate 7 is an arc-shaped plate and protrudes towards the turbid gas inlet 3 direction. A plurality of first ventilation holes 12 are provided on the first static dispersion plate 7. The aperture of the plurality of first ventilation holes 12 increases successively from the direction close to the turbid gas inlet 3 to the direction far from the turbid gas inlet 3.

[0028] A first static dispersion plate 7 with a number of first ventilation holes 12 is arranged between the first filter element 6 and the turbid gas inlet 3 of this device. When the air flow impacts on the first static dispersion plate 7, the first static dispersion plate 7 is an arc-shaped plate and protrudes towards the turbid gas inlet 3. The air flow diffuses around along the protruding arc surface. Since the aperture of the first ventilation holes 12 increases sequentially from the direction close to the turbid gas inlet 3 to the direction far from the turbid gas inlet 3, that is, the aperture of the first ventilation holes 12 directly impacted by the air flow is relatively small, and the aperture of the first ventilation holes 12 far from the direct impact of the air flow is relatively large. In this way, the air flow will be distributed relatively evenly on the entire first static dispersion plate 7. The evenly distributed air flow can contact a larger area of the first filter element 6, improve the effective utilization rate of the entire first filter element 6, reduce the local use intensity of the first filter element 6, and improve the filtration efficiency.

[0029] There is a first mixing chamber 14 between the outer shell 10 and the first static dispersion plate 7 at the turbid gas inlet 3. After the air flow enters the first mixing chamber 14 through the turbid gas inlet 3, it disperses in the first mixing chamber 14 and then flows downstream through the first static dispersion plate 7;

[0030] And / or there is a second mixing chamber 15 between the outer shell 10 and the first filter element 6 at the first static dispersion plate 7. After the air flow is dispersed by the first static dispersion plate 7, it enters the second mixing chamber 15 and then disperses to the first filter element 6.

[0031] As an implementation manner, the length direction of the outer shell 10 is defined as the first stretching direction, and the two ends of the outer shell 10 in the first stretching direction are respectively the front end and the rear end. The outer shell 10 includes a shell main body 5 integrally formed along the first stretching direction and two end covers 1. The front end and the rear end of the shell main body 5 are respectively sealed by an end cover 1. The turbid gas inlet 3 and the clean gas outlet 4 are respectively located at the upper part and the lower part of the shell main body 5. The shell main body 5 can be formed by stretching, and the cross-sectional shape is the same along one direction. During preparation, a long shell main body 5 can be integrally stretched and then cut into segments. After cutting into segments, the two ends of the shell main body 5 are blocked by two end covers 1. The outer shell 10 with this structure is easier to be integrally formed and improves the manufacturing efficiency.

[0032] In order to facilitate the installation of the end cover 1, a stretching groove 8 is integrally formed on the outer peripheral side of the shell main body 5 along the first stretching direction. Threaded cylinders 9 are fixedly connected to both ends of the stretching groove 8. Ears 2 are provided at the positions corresponding to the stretching groove 8 on the circumferential side of the end cover 1. The ears 2 are fixed to the threaded cylinders 9 by screws. The threaded cylinders 9 are fixed in the stretching groove 8, and then the end cover 1 is fixed to the threaded cylinders 9 by screws.

[0033] One side of the end cover 1 away from the shell main body 5 has an installation portion 27, and the installation portion 27 is used for fixed assembly with external equipment, which is convenient for installation on the vehicle body.

[0034] On the inner wall of the shell main body 5, a first sliding groove 20 is integrally formed along the first stretching direction. On both sides of the first static dispersion plate 7, first long strip parts 19 are integrally formed along the first stretching direction. The first long strip parts 19 are in limit assembly with the first sliding groove 20. The first static dispersion plate 7 is assembled with the shell main body 5 by inserting the first long strip parts 19 into the first sliding groove 20. The assembly is simple and easy to maintain.

[0035] On the inner wall of the shell main body 5, a first support rib 11 is integrally formed along the first stretching direction. The first filter element 6 is in limit assembly between the first static dispersion plate 7 and the first support rib 11. The first filter element 6 is installed and removed by pulling. The installation method is simple.

[0036] To improve the gas purity, the filter structure further includes a second static dispersion plate 24 and a second filter element 26 located inside the outer shell 10. The second static dispersion plate 24 and the second filter element 26 are located between the first filter element 6 and the clean gas outlet 4. The second static dispersion plate 24 is located between the first filter element 6 and the second filter element 26. The second static dispersion plate 24 is an arc-shaped plate and protrudes towards the dirty gas inlet 3. A plurality of second ventilation holes 23 are formed on the second static dispersion plate 24. The diameters of the plurality of second ventilation holes 23 increase in sequence from the direction close to the dirty gas inlet 3 to the direction far from the dirty gas inlet 3. The second static dispersion plate 24 and the second filter element 26 are provided in this device, and the second filter element 26 is used to further improve the gas filtration fineness.

[0037] There is a third mixing cavity 16 between the outer shell 10 and the first filter element 6;

[0038] and / or there is a fourth mixing cavity 17 between the outer shell 10 and the second filter element 26;

[0039] and / or there is a fifth mixing cavity 18 between the outer shell 10 and the clean gas outlet 4. The principle is the same as above. By using multiple mixing cavities, the air flow is made more uniform, and the filtration efficiency is improved.

[0040] Define the length direction of the outer shell 10 as the first stretching direction. The two ends of the outer shell 10 in the first stretching direction are the front end and the rear end respectively. The outer shell 10 includes a shell main body 5 and two covers 1 integrally formed along the first stretching direction. The front end and the rear end of the shell main body 5 are sealed by a cover 1 respectively. The dirty gas inlet 3 and the clean gas outlet 4 are located on the upper part and the lower part of the shell main body 5 respectively;

[0041] On the inner wall of the shell main body 5, a second sliding groove 21 is integrally formed along the first stretching direction. On both sides of the second static dispersion plate 24, second long strip parts 22 are integrally formed along the first stretching direction. The second long strip parts 22 are in limit assembly with the second sliding groove 21;
