In the existing sensor cover, the upper end seal is designed into a concave inverted buckle shape by a rubber sealing piece and a convex inverted buckle shape by a plastic sensor cover, and the two are buckled together by interference fit. The assembly needs manual work, the production efficiency is low, and is influenced by plastic parts, rubber part flashes and clamping openings, the rubber sealing part is easily pulled off from a sensor by axial friction of a steering shaft in the assembly process or is unscrewed in a high-temperature and low-temperature environment by radial rotating friction in the life cycle, so that external oil, water, dust and the like are invaded and polluted, the steering force is increased, and the sealing performance is gradually lost. The lower end sealing is completed by matching an O-shaped ring assembled on a sensor cover with a steering engine, in the design scheme, the rubber ring groove flash of the plastic sensor cover needs to be controlled within 0.04mm, the clamping opening needs to be controlled within 0.02mm, and the rubber ring avoids the flash scratching of a hard rubber piece as much as possible in the assembling direction, but the sealing potential safety hazard is large and the defects exist because the flash scratching cannot be avoided by 100% in the actual production. The lower end sealing is realized by coating liquid glue on the bottom plane of the shell by a customer and fastening the shell assembly and the assembly surface of the steering engine through three bolts.
In view of the above-mentioned drawbacks in the prior art, the present applicant has improved a sensor cover and has filed a chinese patent (publication No. CN 108757940A), which discloses a sensor cover including a plastic housing, a rubber dust ring, a rubber oil seal, and a metal bushing; the upper part of the rubber dustproof ring is provided with a high-elasticity closing-in lip part, the outer side part of the rubber dustproof ring is provided with a circle of convex transverse bone positions, the outer side part of the rubber dustproof ring is coated with a glue layer, and the plastic shell and the rubber dustproof ring are integrally formed in an injection molding mode; the rubber oil seal is internally coated with a metal framework, the inner sealing surface of the rubber oil seal is provided with a plurality of high-elasticity sealing lips, and the outer side of the inner sealing surface of the rubber oil seal is provided with a tightening spring ring; the rubber oil seal is arranged in the plastic shell and tightly presses the lower end of the rubber oil seal through a plastic block; a plurality of metal bushings are embedded on the outer edge of the lower part of the plastic shell; the lower part of the plastic shell is fixedly connected with the sensor shell through solid glue and a metal lining bolt.
