Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically a steering column cover assembly for automobiles. Background Technology

[0002] The automotive steering column cover assembly is a core component installed below the steering wheel and covering the steering column. Its main function is to protect the core mechanical structure and wiring harness of the steering system, improve the safety and aesthetics of the vehicle interior. This assembly usually consists of an upper cover and a lower cover that are set up to correspond to each other. The two are spliced ​​together by clips, bolts or modular snap-fit ​​structures to form a complete cover for the steering column, achieving all-round protection for the internal structure.

[0003] However, existing automotive steering column cover assemblies still have significant defects: the mating holes and clearance holes on the upper and lower covers used to adapt to the steering column, combination switch, and wiring harness lack reliable sealing design. They rely solely on the simple covering of the cover body, which allows foreign objects such as water, dust, and oil to easily intrude through the gaps in the holes. This not only accelerates the wear and aging of steering system components but may also cause electrical faults, seriously affecting the reliability and service life of the steering system.

[0004] Therefore, a steering column guard assembly for automobiles is proposed to address the above-mentioned problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a steering column cover assembly for vehicles, which has the advantages of multi-layer structure for enhanced protection, reliable hole sealing, precise installation and positioning, and excellent sound insulation and noise reduction.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vehicle steering column guard assembly, comprising an upper guard and a lower guard arranged correspondingly above and below, wherein the front and sides of the upper guard and the lower guard are respectively provided with mating holes and clearance holes, and the inner walls of the mating holes and clearance holes are provided with sealing strips, and the inner walls of the mating holes and clearance holes are provided with guide grooves, wherein guide strips are slidably connected to the guide grooves, and the guide strips are disposed on the sealing strips.

[0007] Preferably, both the upper and lower protective covers are composed of a protective outer layer, a structural reinforcement layer, a sound insulation and noise reduction layer, a sealing buffer layer, and a protective inner layer arranged sequentially from the outside to the inside.

[0008] Preferably, the guide groove has a semi-circular structure, with one end open and the other end closed.

[0009] Preferably, a first magnet is fixed to the inner wall of the closed end of the guide groove, and a second magnet is fixed to the end of the guide strip corresponding to the first magnet.

[0010] Preferably, the contact surfaces of the upper and lower protective covers are respectively provided with positioning grooves and positioning posts, and the positioning posts and positioning grooves correspond to each other.

[0011] Preferably, a sealing gasket is provided between the upper protective cover and the lower protective cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The design of the sealing strip, guide groove, and guide strip at the mating hole and clearance hole of this utility model further enhances the sealing reliability and assembly convenience of the protective cover. The sealing strip fits tightly against the hole wall, effectively preventing the intrusion of foreign objects such as water, dust, and oil, providing additional protection for the core components of the steering system. The sliding fit of the guide groove and guide strip allows the sealing strip to be accurately aligned during installation, avoiding the problems of easy displacement and detachment of traditional sealing structures, ensuring long-term stable sealing effect. If combined with the magnetic attraction design of the first and second magnets, additional fixing force can be formed after the guide strip is in place, further improving the reliability of the sealing structure. This design not only significantly improves the sealing protection level of the protective cover hole, but also simplifies the installation and subsequent maintenance process of the sealing strip, taking into account both practicality and durability, and effectively solving the industry pain points of sealing failure and easy intrusion of foreign objects in traditional protective cover hole. 2. The multi-layered structure design of the upper and lower protective covers of this utility model has significant comprehensive advantages. The outer protective layer can effectively resist external impacts and scratches, building the first line of defense against wear for the internal structure. The structural reinforcement layer significantly enhances the overall structural strength of the cover, preventing deformation under external force or during long-term use, ensuring continuous and stable coverage of the steering column. The sound insulation and noise reduction layer can efficiently absorb the noise of the steering system and the vibration noise generated by the vehicle, greatly reducing the transmission of noise into the vehicle and significantly improving driving comfort. The sealing and buffering layer fills the gap between the cover and surrounding components through elastic deformation, avoiding abnormal noise caused by hard contact and initially blocking the intrusion of foreign objects such as dust and moisture. The inner layer directly isolates the steering column, wiring harness and the cover body, preventing friction and wear, and effectively extending the service life of internal components. The five-layer structure works together to comprehensively improve the performance of the cover from multiple dimensions such as impact resistance, structural strength, noise reduction, foreign object protection and component protection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides a steering column cover assembly for vehicles, including an upper cover 1 and a lower cover 2 arranged correspondingly. The front and sides of the upper cover 1 and the lower cover 2 are respectively provided with mating holes 3 and clearance holes 4. The sealing strips 5 on the inner walls of the mating holes 3 and the clearance holes 4 can effectively prevent the intrusion of foreign objects such as water, dust, and oil, ensuring the cleanliness of the core components of the steering system. The sliding fit between the guide groove 6 and the guide strip 7 can ensure that the sealing strip 5 is accurately aligned and not easily displaced during installation, maintaining the sealing performance for a long time. The inner walls of the mating holes 3 and the clearance holes 4 are provided with sealing strips 5. The inner walls of the mating holes 3 and the clearance holes 4 are provided with guide grooves 6, and the guide grooves 6 are slidably connected to the guide strips 7, which are located on the sealing strips 5.

[0021] Specifically, both the upper protective cover 1 and the lower protective cover 2 are composed of a protective outer layer 101, a structural reinforcement layer 102, a sound insulation and noise reduction layer 103, a sealing buffer layer 104, and a protective inner layer 105 arranged sequentially from the outside to the inside. The protective outer layer 101 resists external impacts and scratches, the structural reinforcement layer 102 enhances the overall strength and prevents deformation, the sound insulation and noise reduction layer 103 absorbs operating noise and improves driving comfort, the sealing buffer layer 104 elastically fills gaps and reduces hard contact noises, and the protective inner layer 105 prevents wear on pipes and wiring harnesses. The five layers work together to achieve multi-dimensional protection.

[0022] Furthermore, the guide groove 6 has a semi-circular structure, with one end of the guide groove 6 being open and the other end being closed. The open end facilitates the quick insertion of the guide strip 7, while the closed end, in conjunction with a magnetic piece, enables the strip to be positioned and fixed, thereby improving assembly efficiency and structural stability.

[0023] Furthermore, a first magnet 8 is fixed to the inner wall of the closed end of the guide slide 6, and a second magnet 9 is fixed to the end of the guide slide 7 corresponding to the first magnet 8. The first magnet 8 and the second magnet 9 magnetically attract each other, which can form an additional fixing force after the guide slide 7 is in place, further preventing the sealing strip 5 from loosening and enhancing the sealing reliability.

[0024] It is worth noting that positioning grooves 10 and positioning posts 11 are respectively provided on the contact surfaces of the upper cover 1 and the lower cover 2. The positioning posts 11 and the positioning grooves 10 correspond to each other. The precise cooperation between the positioning posts 11 and the positioning grooves 10 can ensure that the upper cover 1 and the lower cover 2 are aligned without offset when spliced, thereby improving the sealing and stability of the overall structure.

[0025] It is worth noting that a sealing gasket is provided between the upper cover 1 and the lower cover 2. The sealing gasket can fill the gap between the upper and lower covers, further blocking dust and moisture from entering and enhancing the overall protective performance.

[0026] Working principle and process: During the assembly stage, the sealing strip 5 is first slidably installed along the guide groove 6 on the inner wall of the mating hole 3 and the clearance hole 4 via its own guide slide 7. Because the guide groove 6 is semi-circular and closed at one end, the slide can smoothly embed and abut against the closed end. At this time, the first magnet 8 in the guide groove 6 and the second magnet 9 on the guide slide 7 magnetically attract each other, realizing the precise positioning and fixing of the sealing strip 5 and preventing its displacement. Then, the upper cover 1 and the lower cover 2 are connected. The positioning groove 10 on the contact surface of the upper cover 1 and the positioning post 11 of the lower cover 2 are precisely matched to ensure that the two are spliced ​​without offset. At the same time, the sealing gasket between the two fills the splicing gap. Finally, The steering column is secured by clips or bolts, forming a complete enclosure. During use, the outer protective layer 101 resists external impacts and scratches, the structural reinforcement layer 102 maintains the overall shape of the cover to prevent deformation and ensure the stability of the enclosure, the sound insulation and noise reduction layer 103 absorbs the noise generated by the steering system and vehicle vibration, improving driving comfort, the sealing and buffer layer 104 elastically fills the gap between the cover and the steering column to reduce hard contact noise, the inner protective layer 105 directly isolates the steering column and wiring harness to prevent friction and wear, and the sealing strips 5 at the holes 3 and 4 continuously prevent the intrusion of water, dust and other foreign objects, ensuring the stable operation of the steering system in all aspects.
