Abstract
The utility model discloses a connection structure for an auto air filter and an insert tube. The connection structure comprises an air filter housing and the insert tube, wherein the insert tube adopts a bent structure; a first clamping structure is inwardly arranged at an air outlet of the air filter housing; a second clamping structure is arranged at one end of the insert tube; the first clamping structure and the second clamping structure are connected in a clamped manner; a threaded hole is formed in the first clamping structure; a through hole allowing a self-tapping screw to penetrate is formed in the second clamping structure; and the self-tapping screw is in fixed connection with the threaded hole. Compared with a traditional connecting mode, the insert tube is shortened, so that the phenomenon of collision between the insert tube and the inner wall of the air filter housing is avoided, and the problem of difficulty in assembly is solved. The connection structure is higher in strength, low in price and easy to implement.
Description
Technical field
The utility model relates to the automotive engine air intake system field, refers in particular to the linkage structure of a kind of air filter for automobile and Inserting Tube.
Background technique
Air-strainer is important component in automotive engine air intake system, with removing suspended particulate impurity contained in the air that enters motor.Along with the raising of automotive performance, air filter also need be considered NVH(vibration noise and uneven compliance except need satisfy fundamental function) noise problem.In order to obtain NVH performance preferably, gas handling system has 3 kinds of optimization methods: 1, increase Inserting Tube in air filter housing; 2, increase the wavelength pipe on the gas handling system pipeline; 3, increase the air filter volume.The tradition assembling mode of method 1 is: Inserting Tube is plugged in the air filter housing air outlet, the method is except needs are considered the effective segment length of Inserting Tube, also increased the Inserting Tube load segment, load segment only is used for installing Inserting Tube, on proposing the NVH performance without impact, and the Inserting Tube total length is increased, cause the assembling difficulty.
China Patent Publication No. CN201531338U, open day on July 21st, 2010, name is called the gas handling system that discloses a kind of motor in the utility model patent of " a kind of gas handling system of motor ", design respectively upper cover Inserting Tube, lower shell body Inserting Tube by upper cover, lower shell body in air cleaner assy, speed air flow in air cleaner assy is even, there is no vortex phenomenon, the speed air flow of filter core upper and lower surface is even, the engine charge comparison of resistance is little, is conducive to the engine power performance.But the Placement of the Inserting Tube of this gas handling system is from outer insertion enclosure interior, has caused waste on material, and assembling is inconvenience comparatively.
The model utility content
The purpose of this utility model is the Inserting Tube assembling difficulty that overcomes air filter for automobile in prior art, and the shortcoming of waste material, provides a kind of assembling simple, the air filter for automobile of economical with materials and the linkage structure of Inserting Tube.
The purpose of this utility model is to be achieved by following technical proposals:
The linkage structure of a kind of air filter for automobile and Inserting Tube, comprise air filter housing and Inserting Tube, air outlet at air filter housing inwardly is provided with the first interface arrangment, and Inserting Tube one end is provided with the second interface arrangment, the first interface arrangment and the second interface arrangment clamping.During assembling, the housing of air-strainer is opened, and the second interface arrangment of Inserting Tube is aimed at from top to down the first interface arrangment and carried out clamping.Inserting Tube is guaranteeing identical effective length, namely can promote in the situation of length of NVH performance, and total length diminishes, and the phenomenon that Inserting Tube and air filter inner walls bump can not occur, and has solved the assembling hard problem.
As a kind of preferred version, the linkage structure of air filter for automobile and Inserting Tube also comprises tapping screw, described the first interface arrangment is provided with tapped hole, and described the second interface arrangment is provided be used to the through hole that passes tapping screw, and tapping screw is fixedly connected with tapped hole.After the first interface arrangment and the second interface arrangment clamping were completed, the effect of tapping screw was to strengthen assembling, made Inserting Tube better fixing.
As a kind of preferred version, Inserting Tube is bending structure.The design of bending structure makes Inserting Tube in the situation that effective length is fixing, more easily is placed in air filter for automobile, and assembly process is simplified.
The beneficial effects of the utility model are that Inserting Tube is compared traditional Placement length and diminished, and the phenomenon that Inserting Tube and air filter inner walls bump can not occur, and has solved the assembling hard problem.And this linkage structure intensity is higher, cheap, be easy to realize.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Wherein: 1, air filter housing, 2, Inserting Tube, the 3, first interface arrangment, the 4, second interface arrangment, 5, tapping screw.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment: the linkage structure of a kind of air filter for automobile and Inserting Tube, its structural representation as shown in Figure 1, comprise air filter housing 1 and Inserting Tube 2, Inserting Tube is bending structure, inwardly be provided with the first interface arrangment 3 in the air outlet of air filter housing, Inserting Tube one end is provided with the second interface arrangment 4, the first interface arrangments and the second interface arrangment clamping.The first interface arrangment is provided with tapped hole, and described the second interface arrangment is provided be used to the through hole that passes tapping screw 5, and tapping screw is fixedly connected with tapped hole.
During assembling, the housing of air-strainer is opened, and the second interface arrangment of Inserting Tube is aimed at from top to down the first interface arrangment and carried out clamping.After the first interface arrangment and the second interface arrangment clamping were completed, tapping screw screwed in tapped hole, strengthened assembling, made Inserting Tube better fixing.Inserting Tube is guaranteeing identical effective length, namely can promote in the situation of length of NVH performance, and total length diminishes, and the phenomenon that Inserting Tube and air filter inner walls bump can not occur, and has solved the assembling hard problem.
