Figure 4 for Figure 2 A magnified view of a section at point A in the middle, taken from below.

[0033] like Figures 1-4 As shown, this embodiment provides a vehicle air filter mounting structure, including a fixing bracket 10 and a hollow buffer 20. The fixing bracket 10 and the air filter body 30 can be connected by bolts, hinges, welding, or integral injection molding. In this embodiment, the fixing bracket 10 and the air filter body 30 are preferably integrally injection molded, and the buffer 20 is sleeved on the outside of the fixing bracket 10. There can be multiple fixing brackets 10, and in this embodiment, three are preferred. When the fixing brackets 10 are installed on the vehicle body, they can be any conventional bracket structure to avoid collisions with other parts.

[0034] The fixing support 10 comprises a connecting portion 11 for fixed connection with the air filter 100, and a mounting portion 12 connected with the connecting portion 11 and used for mounting on a vehicle body. The fixing support 10 is provided with a reinforcing rib 13 for increasing strength. The mounting portion 12 comprises a first mounting section 121 and a second mounting section 122 which are integrally formed. The fixing support 10 can also be provided with a reinforcing groove for increasing support strength.

[0035] The first mounting section 121 is provided with a plurality of lightening grooves, and is composed of a cylindrical first mounting section 1211 and a circular-taip first mounting section 1212 which are integrally formed. One end surface of the cylindrical first mounting section 1211 abuts against the connecting portion 11, and the end surface with a smaller diameter of the circular-taip first mounting section 1212 abuts against the second mounting section 122. The sidewall of the circular-taip first mounting section 1212 is provided with a plurality of penetrating lightening grooves. This design can increase the contact area with the inner ring of the buffer 20, reduce the total mass of the fixing support 10, reduce the cost, and reduce the pressure on the frame 200.

[0036] The second mounting section 122 is in a semi-cylindrical shape, and one end surface thereof is radially expanded to form a convex clamping portion 123 which is used for limiting the buffer 20 in the axial direction. The sidewall of the clamping portion 123 is in an arc shape, which facilitates the stress of the buffer 20 during installation.

[0037] The second mounting section 122 is provided with a second limiting rib 124 extending along the length direction of the second mounting section 122 on one side, which is used for limiting the relative position of the fixing support 10 and the buffer 20. The second mounting section 122 is in a semi-cylindrical shape which is low in cost, and the second limiting rib 124 extending along the length direction of the rectangular side is arranged on the rectangular side, and the second limiting rib 124 is clamped with the inner ring of the buffer 20, thereby increasing the friction force between the fixing support 10 and the buffer 20. This connecting mode makes the fixing support 10 more stable.

[0038] Figure 5 It is a front view of the buffer 20 in the embodiment of the utility model. Figure 6 It is a plane cross-sectional view of the buffer 20 in the embodiment of the utility model. Figure 7 It is an isometric cross-sectional view of the buffer 20 in the embodiment of the utility model.

[0039] As Figures 5-7As shown, the buffer 20 comprises a first abutting portion 22, a sleeving portion 23, a second abutting portion 24, and a clamping portion 25. The first abutting portion 22, the sleeving portion 23, and the clamping portion 25 are cylindrical, the second abutting portion 24 is circular truncated cone-shaped, and the first abutting portion 22, the sleeving portion 23, the second abutting portion 24, and the clamping portion 25 are coaxially connected in sequence. The buffer 20 is sleeved outside the first mounting section 121 and the second mounting section 122.

[0040] Specifically, the first abutting portion 22 and the sleeving portion 23 are sleeved at one end of the first mounting section 121, the second abutting portion 24 is sleeved at the other end of the first mounting section 121 and the second mounting section 122, and the clamping portion 25 is clamped with the clamping portion 123. The diameter of the second abutting portion 24 gradually decreases along the direction from the first abutting portion 22 to the clamping portion 25, the diameter of the end face of the one end of the second abutting portion 24 toward the first abutting portion 22 is greater than the diameter of the first abutting portion 22, which is beneficial to the stress of the frame 200 during installation and facilitates the installation of the frame 200. The diameter of the end face of the one end of the second abutting portion 24 toward the clamping portion 25 is smaller than the diameter of the first abutting portion 22 and equal to the diameter of the clamping portion 25. The clamping portion is designed at the lower end of the second abutting portion 24 to further increase the friction and buffering force. In addition, the outer diameter of the sleeving portion 23 is smaller than the maximum outer diameter of the first abutting portion 22 and the second abutting portion 24, which has the advantage that the first abutting portion 22 and the second abutting portion 24 can both limit the installation plate on the frame 200, preventing the position of the sleeving portion 23 from moving in the mounting hole of the installation plate of the frame 200 and the installation plate of the frame 200 from falling off when the stress is too large, thereby causing the air filter 100 to be unstable.

[0041] In addition, the first abutting portion 22 is provided with a first mounting groove 221 which is cylindrical and coaxial with the first abutting portion 22, and the first mounting groove 221 is used to accommodate the first mounting section 121. The second abutting portion 24 is provided with a second mounting groove 241 which is cylindrical and coaxial with the second abutting portion 24, and the second mounting groove 241 is used to accommodate the first limiting rib 21. Specifically, the cylindrical first mounting section 121 of the first mounting section 121 is arranged in the first mounting groove 221.

[0042] The buffer 20 further comprises a first limiting rib 21 arranged on the inner surface and used to limit the relative position of the fixed support 10 and the buffer 20. The first limiting rib 21 is in a plurality and arranged in a radial manner, one end of each first limiting rib 21 is embedded into the bottom of the first mounting groove 221, the other end extends to the bottom of the second mounting groove 241, and the plurality of first limiting ribs 21 converge toward the axis direction of the hollow buffer 20, and the whole is conical, which can better limit the relative position of the fixed support 10 in the buffer 20.

[0043] Figure 8This is a schematic diagram of the structure in which the vehicle air filter 100 is mounted on the vehicle frame 200 via the vehicle air filter 100 mounting structure in an embodiment of this utility model.

[0044] like Figure 8 As shown, another embodiment of the present invention provides an air filter 100, including an air filter body 30 and an air filter mounting structure provided in this embodiment of the present invention, wherein the air filter body 30 and the air filter 100 mounting structure are fixedly connected.

[0045] Another embodiment of this utility model provides a vehicle, including an air filter 100 and a frame 200 provided in the embodiments of this utility model. A mounting plate is provided on the frame 200, and a mounting hole is provided on the mounting plate. The air filter 100 is arranged in the mounting hole and installed on the frame 200. The air filter 100 is also fixedly connected to an intake pipe 300. In addition, the number of fixing brackets 10 in this utility model is preferably two. Two fixing brackets 10 located on one side of the air filter 100 fix the air filter 100 to the frame 200, and the other fixing bracket 10 fixes the air filter 100 to other parts of the vehicle body. This design makes the center of gravity of the air filter body 30 basically at the same height as the three fixing brackets 10, so that the air filter body 30 is not easy to shake when the vehicle moves, and the stability is better.

[0046] Using the technical solution of the above embodiments, the fixed bracket 10 is fixedly connected to the air filter body 30. The inner ring of the hollow buffer 20 is sleeved on the fixed bracket 10, and the outer ring's sleeve portion 23 is sleeved in the mounting hole on the frame 200 mounting plate, so that the fixed bracket 10 and the frame 200 do not directly contact each other, thus playing a buffering role when the fixed bracket 10 is subjected to vibration. In addition, the boss-shaped snap-fit ​​portion 123 snaps into the snap-fit ​​portion 25 of the buffer 20. The first limiting rib 21 in the buffer 20 and the second limiting rib 124 on the fixed bracket 10 further limit the position of the fixed bracket 10 within the buffer 20, which can reduce the shaking of the fixed bracket 10 when the vehicle moves, thereby keeping the air filter 100 stable. The reinforcing rib 13 on the fixed bracket 10 further increases the strength of the fixed bracket 10, making the fixed bracket 10 less prone to deformation. In addition, the center of gravity of the air filter body 30 and the multiple fixed brackets 10 are basically at the same height, so that the air filter body 30 is less prone to shaking when the vehicle moves, and the stability is very good.

[0047] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
