Description

Technical Field

[0001] The utility model relates to the technical field of horizontal air filters for commercial vehicles. The air filter is characterized by long maintenance mileage, low flow resistance, and a new installation layout structure. Background Art

[0002] Existing horizontal air filters for commercial vehicles usually adopt cylindrical corrugated filters, which cause the air filter to occupy the chassis space and cannot meet the customer's needs. Therefore, it is necessary to develop a horizontal air filter structure for commercial vehicles, and the cross-section of its filter element is in a runway shape.

[0003] With the development of technology, more and more devices need to be installed in the installation space of commercial vehicles, making the installation space in commercial vehicles increasingly compact. In order to save space more fully, the utility model innovatively proposes a technical solution of horizontally installing the air filter on the beam bracket at the right rear of the cab. However, when the air filter is installed in this position, there is a lack of space to open the maintenance end cover in the axial direction (horizontal direction), which is not convenient for maintenance.

[0004] Therefore, the utility model has developed an air filter that can open the maintenance end cover upward, and the installation structure of the filter element is convenient for up and down installation or disassembly. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a horizontal air filter structure for commercial vehicles, which can open the maintenance end cover upward, and the installation structure of the filter element is convenient for up and down installation or disassembly.

[0006] To achieve the above purpose, the utility model provides a horizontal air filter structure for commercial vehicles, including a horizontally arranged horizontal shell. One end of the shell is integrally provided with an air inlet, and the shell at the opposite end of the air inlet is connected with an air outlet;

[0007] The top of the shell is open and connected with a maintenance end cover, and the maintenance end cover is clamped or screwed to the shell; a filter element is arranged in the shell;

[0008] The filter element includes a filter layer with a cross-section in a runway shape. The air inlet end of the filter layer is connected with an air inlet end frame, and the air outlet end of the filter layer is connected with an air outlet end frame;

[0009] Both ends in the length direction of the air inlet end frame are connected with handles. The air outlet end of the air outlet end frame is connected with a sealing rubber ring in the circumferential direction. The sealing rubber ring protrudes from the filter layer and the air outlet end frame in the air outlet direction. The air outlet extends into the air outlet end frame and forms a radial sealing fit with the sealing rubber ring; the air inlet is communicated with the air inlet end frame, and an air inlet cavity is formed between the air inlet and the air inlet end frame;

[0010] Two vertical grooves are provided on the inner surface of the shell corresponding to the handles one by one, and the handles are embedded in the corresponding grooves from top to bottom.

[0011] The handle is provided with a handle groove, and the upper surface of the handle is provided with an arc-shaped notch for facilitating the insertion of fingers into the handle groove.

[0012] A diversion port is provided in the intake cavity at the intake port; the intake end of the diversion port faces the intake port, the outlet end of the diversion port faces the intake end of the filter element, the outlet end of the diversion port is larger than its intake end, several diversion vanes and partition pieces perpendicular to the diversion vanes are provided in the diversion port, the diversion vanes are inclined, and the diversion vanes and the partition pieces divide the diversion port into several flow channels; the virtual connection line between the center of the diversion port and the center of the intake end of the filter element is called the reference line, and each flow channel is parallel to the reference line; the extension line of the side wall of the diversion port correspondingly covers the entire intake end of the filter element.

[0013] Several insertion positioning plates are connected to the outer wall of the diversion port at intervals, and several positioning slots are provided on the inner wall of the housing at the intake port corresponding to the insertion positioning plates one by one, and each insertion positioning plate is inserted into the corresponding positioning slot; a screw connection seat is provided at the bottom of the diversion port, an installation hole is provided on the screw connection seat, a screw is provided in the installation hole, and the screw is connected to the housing downward.

[0014] The air outlet is welded or connected to the housing by screws; several horizontally arranged mounting brackets are connected to the housing at intervals in the circumferential direction, and vertical holes are provided on each mounting bracket, and the mounting brackets are used to horizontally mount the housing on the outside of the commercial vehicle frame at the right rear of the cab.

[0015] The outer surface of the maintenance end cover is convexly provided with transverse reinforcing ribs, the inner surface of the maintenance end cover is provided with guiding vertical ribs and a limiting platform, and the limiting platform restricts the vertical position of the filter element downward.

[0016] An alarm interface for installing an alarm is provided on the outer wall of the air outlet.

[0017] A support frame for supporting the air outlet is provided inside the intake end of the air outlet.

[0018] The upper surface of the bottom wall of the housing is provided with convex ribs for supporting the filter element.

[0019] The utility model has the following advantages:

[0020] The two vertical embedding grooves and the inner surface of the air outlet end of the housing jointly restrict the position of the filter element in the horizontal plane (i.e., restrict the positions in the X and Y directions), but do not restrict the position of the filter element in the vertical direction (i.e., the Z direction position), providing a structural basis for the up and down installation or disassembly of the filter element.

[0021] The arc-shaped notch is very convenient for inserting fingers into the handle groove to lift the filter element upward when disassembling the filter element.

[0022] If there is enough space, it is most appropriate to set both the air inlet and the air outlet in the middle of the housing (corresponding to the middle of the filter element). However, the installation space of some models limits the location of the air inlet, and the air inlet must be set on the side of the housing air inlet end. In this way, after the gas in the air inlet enters the air inlet cavity, the filter layer facing the air inlet passes most of the airflow, while the filter layer far from the air inlet only passes a small part of the filter layer, so that the filter layer cannot be fully utilized, the flow resistance is increased, and the service life of the filter layer is uneven. When the filter layer with more airflow is blocked and reaches its service life, the service life of the filter layer with less airflow is far from reaching the service life, thus greatly shortening the service life of the filter element and shortening the maintenance mileage. Therefore, for air filters that are limited by the installation space and can only be installed eccentrically, it is necessary to set a guide port.

[0023] Each flow channel is parallel to the reference line, and the extension line of the side wall of the guide port corresponds to the air inlet end covering the entire filter element, which can evenly guide the air intake to various parts of the filter element's air inlet end, allowing the airflow to pass through the filter layer more evenly, making full use of the filter layer, reducing flow resistance, increasing the overall service life of the filter element, and extending maintenance mileage.

[0024] The installation structure of the air guide port is simple and convenient. During assembly, first insert the plug-in positioning plates of the air guide port into the corresponding positioning slots from top to bottom to achieve horizontal positioning of the positioning plates, and then tighten the screws to achieve vertical positioning of the air guide port. When disassembling, just perform the reverse action. Both installation and disassembly are very convenient, meeting the needs of maintenance in the upper and lower directions.

[0025] The maintenance cover is used as a structure to restrict the vertical position of the filter element. Therefore, after opening the maintenance cover, the maintenance cover can be easily pulled up.

[0026] The alarm interface is convenient for installing the alarm. The support frame can prevent the air inlet end of the air outlet from being deformed, thereby preventing the seal between the air outlet and the sealing rubber ring from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] As Figures 1 to 11 shown, a horizontal air filter structure for commercial vehicles of the present utility model includes a horizontally arranged horizontal housing 1. One end of the housing 1 is integrally provided with an air inlet 2, and the housing 1 at the opposite end of the air inlet 2 is connected with an air outlet 3. The top of the housing 1 is open and connected with a maintenance end - cover 4. The maintenance end - cover 4 is snap - connected or screwed to the housing 1 (preferably connected by screws 5 as shown in the figure); A straight - through filter element is arranged inside the housing 1;

[0039] The filter element includes a filter layer 6 with a runway - shaped cross - section. The intake end of the filter layer 6 is connected with an intake - end frame 7, and the outlet end of the filter layer 6 is connected with an outlet - end frame 8;

[0040] Both ends of the intake - end frame 7 in the length direction are connected with handles 9. The outlet end of the outlet - end frame 8 is connected with a sealing rubber ring 10 in the circumferential direction (here, the sealing rubber ring 10 is preferably a PU sealing strip). The sealing rubber ring 10 protrudes from the filter layer 6 and the outlet - end frame 8 in the outlet direction. The air outlet 3 extends into the outlet - end frame 8 and forms a radial sealing fit with the sealing rubber ring 10 in the inner - outer direction along the circumference; The air inlet 2 communicates with the intake - end frame 7, and an intake cavity 11 is formed between the air inlet 2 and the intake - end frame 7;

[0041] Two vertical grooves 12 corresponding to the handles 9 are provided on the inner surface of the housing 1. The handles 9 are inserted into the corresponding grooves 12 from top to bottom.

[0042] The two vertical grooves 12 and the inner surface of the outlet end of the housing 1 jointly restrict the position of the filter element in the horizontal plane (i.e., restrict the positions in the X - direction and Y - direction), but do not restrict the position of the filter element in the vertical direction (i.e., the Z - direction position), providing a structural basis for installing or disassembling the filter element up and down.

[0043] A handle groove 13 is provided in the handle 9, and an arc-shaped notch 14 is provided on the upper surface of the handle 9 for convenient insertion of fingers into the handle groove 13. The arc-shaped notch 14 is very convenient for inserting fingers into the handle groove 13 to lift the filter element upward when removing the filter element.

[0044] A guide port 15 is provided in the air inlet cavity 11 at the air inlet 2; the air inlet end of the guide port 15 faces the air inlet 2, the air outlet end of the guide port 15 faces the air inlet end of the filter element, the air outlet end of the guide port 15 is larger than its air inlet end, a plurality of guide blades 16 and a separator 17 perpendicular to the guide blades 16 are provided in the guide port 15, the guide blades 16 are arranged obliquely, and the guide blades 16 and the separators 17 divide the guide port 15 into a plurality of flow channels 18; the virtual line between the center of the guide port 15 and the center of the air inlet end of the filter element is called the reference line, and each flow channel 18 is parallel to the reference line; the extension line of the side wall of the guide port 15 corresponds to the air inlet end covering the entire filter element. In this embodiment, if the side wall of the guide port 15 parallel to the guide blade 16 is also regarded as a guide blade, then there are four guide blades 16 in total.

[0045] If there is enough space, it is most appropriate to set both the air inlet 2 and the air outlet 3 in the middle of the housing 1 (corresponding to the middle of the filter element). However, the installation space of some models limits the location of the air inlet 2, and the air inlet 2 must be set on the side of the air inlet end of the housing 1. In this way, after the gas in the air inlet 2 enters the air inlet cavity 11, the filter layer 6 facing the air inlet 2 passes through most of the airflow, while the filter layer 6 far from the air inlet 2 only passes through a small part of the filter layer 6, so that the filter layer 6 cannot be fully utilized, the flow resistance is increased, and the service life of the filter layer 6 is uneven. When the filter layer 6 with more airflow is blocked and reaches its service life, the service life of the filter layer 6 with less airflow is far from reaching the service life, thereby greatly shortening the service life of the filter element and shortening the maintenance mileage. Therefore, for air filters that are limited by the installation space and can only be installed eccentrically with the air inlet 2, it is necessary to set a guide port 15.

[0046] Each flow channel 18 is parallel to the reference line, and the extension line of the side wall of the guide port 15 corresponds to the air inlet end covering the entire filter element, which can evenly guide the air intake to various parts of the air inlet end of the filter element, so that the airflow passes through the filter layer 6 more evenly, so that the filter layer 6 is fully utilized, the flow resistance is reduced, the overall service life of the filter element is increased, and the maintenance mileage is extended.

[0047] The outer wall of the diversion port 15 is connected with a plurality of inserted positioning plates 19 at intervals. The inner wall of the housing 1 at the air inlet 2 is provided with a plurality of positioning slots 20 corresponding to the inserted positioning plates 19 one by one, and each inserted positioning plate 19 is inserted into the corresponding positioning slot 20; a screwing seat 21 is arranged at the bottom of the diversion port 15, an installation hole 22 is arranged on the screwing seat 21, a screw 5 is arranged in the installation hole 22, and the screw 5 is connected downward with the housing 1. In this embodiment, three inserted positioning plates 19 and three positioning slots 20 are respectively arranged.

[0048] The installation structure of the diversion port 15 is simple and convenient. During assembly, first insert each inserted positioning plate 19 of the diversion port 15 into the corresponding positioning slot 20 from top to bottom to realize the positioning of the positioning plate in the horizontal direction, and then tighten the screw 5 to realize the vertical positioning of the diversion port 15. When disassembling, just perform the reverse operation. Both installation and disassembly are very convenient, meeting the need for maintenance in the up and down directions.

[0049] The air outlet 3 is welded to or connected to the housing 1 by screws 5; a plurality of horizontally arranged mounting brackets 23 are connected to the housing 1 at intervals in the circumferential direction, and each mounting bracket 23 is provided with a vertical hole 24. The mounting brackets 23 are used to horizontally mount the housing 1 outside the commercial vehicle frame on the right rear of the cab.

[0050] The outer surface (i.e., the upper surface) of the maintenance end cover 4 is convexly provided with transverse reinforcing ribs 25, and the inner surface (i.e., the lower surface) of the maintenance end cover 4 is provided with guiding vertical ribs 26 and a limiting platform 27. The limiting platform 27 restricts the vertical position of the filter element downward. As a structure for restricting the vertical position of the filter element, the maintenance end cover 4 can be conveniently lifted upward after being opened.

[0051] The outer wall of the air outlet 3 is provided with an alarm interface 28 for installing an alarm. The alarm interface 28 facilitates the installation of the alarm. Inside the air inlet end of the air outlet 3, a support frame 29 for supporting the air outlet 3 is provided. The support frame 29 can prevent the air inlet end of the air outlet 3 from deforming, thereby avoiding the damage of the seal between the air outlet 3 and the sealing rubber ring 10.

[0052] On the upper surface of the bottom wall of the housing 1, a convex rib 30 for supporting the filter element is provided.

[0053] During assembly, first weld or connect the air outlet 3 to the housing 1 by screws 5, and the air inlet end of the air outlet 3 extends into the housing 1. There is no order for installing the filter element and the diversion port 15, but it is more appropriate to install the filter element first and then the diversion port 15, because the diversion port 15 only requires vertical operation, while the filter element has a process from being inclined to being pressed vertically, which requires a relatively larger installation operation space compared to installing the diversion port 15.

[0054] When installing the filter element, first put the sealing rubber ring 10, i.e., the PU sealing strip, on the outer circumferential surface of the intake end of the air outlet 3, and then press down the intake end of the filter element to make the handle 9 embed into the corresponding slot 12, positioning the X-direction and Z-direction positions of the filter element so that the filter element cannot move in the horizontal direction.

[0055] When installing the diversion port 15, place the diversion port 15 into the housing 1 from top to bottom vertically. At the same time, align each plugging positioning plate 19 with and insert it into the corresponding positioning slot 20 to fix the horizontal position of the diversion port 15. Finally, tighten the screw 5 downward to fix the vertical position of the diversion port 15.

[0056] Cover the maintenance end cover 4, use the screw 5 to connect the maintenance end cover 4 and the housing 1, and the limiting platform 27 limits the vertical position of the filter element downward to fix the filter element. When in use, the utility model is arranged at the right rear of the cab, lies flat and is installed outside the girder, is connected to the in-place intake duct through the mounting bracket 23, and the clean pipeline connected to the air outlet 3 is connected to the supercharger.

[0057] When the filter element needs to be replaced or maintained, it is not necessary to disassemble the housing 1 from the motor vehicle. Only need to open the maintenance end cover 4, insert the finger into the handle groove 13 from the arc-shaped notch 14, and then pull up the filter element to perform the replacement or maintenance operation on the filter element, which is very convenient.

[0058] The above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: the present invention can still be modified or equivalently replaced, and any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
