Technical Field

[0001] The utility model relates to the technical field of auto parts, in particular to a steering column dust cover. Background Art

[0002] With the rapid development of the automotive industry, vehicles are becoming increasingly versatile, and consumers are demanding higher levels of comfort. This has led to the emergence of a slew of outstanding automakers, creating a highly competitive market. Vehicle comfort, sound insulation, and sealing have also gradually improved from their previous generally poor performance. The dust cover for the intermediate shaft is installed between the engine compartment and the driver's cabin, at the front wall of the intermediate shaft. It primarily provides water, sound, and dust insulation, and its quality directly impacts the overall vehicle's sealing and noise levels.

[0003] In order to improve the dustproof and waterproof, soundproof and noise-reducing, and sealing performance of a car, the utility model provides an intermediate shaft dust cover which can meet the requirements of waterproof and noise reduction, is easy to assemble, and is economical and practical. Utility Model Content

[0004] In view of the above-mentioned deficiencies, the utility model provides a double-bearing plastic snap-on intermediate shaft dust cover with a corrugated structure, which has the characteristics of easy assembly, economy and practicality, and good water-isolating and noise-reducing effects.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A steering column dust cover, comprising a lower dust cover,

[0007] An upper dust cover frame, the upper dust cover frame being arranged on the upper surface of the outwardly folded portion of the upper end port of the lower dust cover;

[0008] A lower dust cover frame, the lower dust cover frame being arranged on the lower surface of the outwardly folded portion of the upper end port of the lower dust cover, the lower dust cover frame being interference fitted with the lower dust cover and being snap-fitted with the upper dust cover frame;

[0009] The upper dust cover is rubber-coated, and the upper dust cover rubber-coated is arranged in the upper dust cover frame and is injection-molded.

[0010] As a further solution of the present invention: a plurality of first buckles are provided on the lower dust cover frame, and the first buckles pass through the through holes on the lower dust cover and are inserted into the clamping holes provided in the upper dust cover frame.

[0011] As a further solution of the present invention: a plurality of second buckles are further provided on the lower dust cover frame.

[0012] As a further solution of the present invention: the lower end port of the lower dust cover is a corrugated structure.

[0013] As a further solution of the present invention: the lower end port of the rubber-coated upper dust cover is a corrugated structure.

[0014] As a further solution of the present invention: the corrugated port of the lower dust cover is press-fitted with a first bearing assembly.

[0015] As a further solution of the present invention, the rubber-coated corrugated port of the upper dust cover is press-fitted with a second bearing assembly.

[0016] As a further solution of the present invention: the first bearing assembly and the second bearing assembly are coaxial.

[0017] Beneficial effects of the utility model:

[0018] This utility model utilizes a direct secondary injection molding process for the upper dust cover frame and TPV overmolding, eliminating the equipment and labor costs associated with manual assembly and offering economical and practical advantages. The front through-hole assembly with the steering intermediate shaft utilizes a snap-on assembly method, which is more convenient than bolt-on assembly, eliminating the need for bolts, nuts, or bushings, saving material costs. This connection method is also highly reliable and stable. The upper and lower corrugated structures effectively absorb deviations during assembly and steering column adjustment, enhancing practicality. The disconnectable dual-bearing structure provides enhanced dust and water resistance, as well as sound insulation and noise reduction. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-5 As shown, the utility model is a steering column dust cover, comprising a lower dust cover 3 and an upper dust cover frame 1, wherein the upper dust cover frame 1 is arranged on the upper surface of the lower dust cover 3 where the upper end port is folded outward; the upper dust cover frame 1 is adapted to the lower dust cover 3 and completely fits on its surface.

[0033] The lower dust cover frame 2 is provided on the lower surface of the outward folded upper end port of the lower dust cover 3, and the lower dust cover frame 2 is interference fitted with the lower dust cover 3; four first clips 21 are provided on the lower dust cover frame 2, and the first clips 21 pass through the through holes 31 on the lower dust cover 3 and are inserted into the snap-fit holes 11 opened in the upper dust cover frame 1.

[0034] In this embodiment, the upper dust cover frame 1, the lower dust cover frame 2 and the lower dust cover 3 can be snapped together and assembled together through four clips. Compared with the traditional fixing method of bolts, this structure is simple to assemble, saves time and effort, saves costs, and is highly economical.

[0035] The lower dust cover frame 2 is also provided with four second clips 22, which engage with holes in the front wall of the vehicle's steering intermediate shaft. The four clips allow the dust cover to be attached to the vehicle via clips. Compared to traditional bolting methods, this structure is simple to assemble, saves time, effort, and cost, and is highly economical.

[0036] The upper dust cover rubber coating 4 is arranged in a hole in the upper dust cover frame 1. The upper dust cover rubber coating 4 is formed by secondary injection molding of the upper dust cover frame 1 and TPV material. This avoids the equipment and labor costs associated with manual assembly and is economical and practical.

[0037] The lower end of the lower dust cover 3 is a corrugated structure. The lower end of the upper dust cover rubber cover 4 is also a corrugated structure.
