[0001] This utility model relates to the field of automotive parts technology, and more specifically, to an armrest cover assembly. Background Technology

[0002] As Chinese car consumers become more sophisticated and their needs become increasingly diverse, coupled with rising living standards, the demand for automobiles is growing significantly. However, the increasing number of domestic brands and the influx of various models from different OEMs into the market each year have intensified competition. Since the beginning of the 21st century, improved economic conditions have driven the entire automotive industry towards a younger demographic, with the pursuit of fashion and trends becoming the dominant theme. Against this backdrop, automotive interior design must cater to the fashion and sporty demands of young people. Simultaneously, intense industry competition has made cost considerations a primary focus in parts design.

[0003] Currently, the rear end of the traditional handrail cover panel typically uses a simple magnetic limiting structure, which has the following drawbacks:

[0004] Traditional magnet fixing methods are prone to falling off, causing abnormal noises; the existing structure has insufficient rib design after injection molding, resulting in low magnet bonding strength.

[0005] To address the aforementioned issues, a new type of handrail cover assembly is urgently needed. This assembly should improve the stability of the magnet's positioning through structural optimization, while simultaneously reducing production costs and increasing the production qualification rate. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a handrail outer cover assembly. The technical problem to be solved by the present invention is: how to improve the unreliability of the magnetic limiting structure at the rear end of the traditional handrail outer cover and the low production qualification rate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a handrail outer cover assembly, comprising a handrail outer cover body, wherein mounting teeth and mounting holes are fixedly provided at the outer edge of the handrail outer cover body, and an upper locking post and a lower locking post are fixedly provided on the back side of the handrail outer cover body, wherein two sets of magnet mounting slots are provided on the back side of the handrail outer cover body, wherein a magnet block is installed in the magnet mounting slot, wherein side connecting buckles are provided on both sides of the magnet mounting slot, wherein a top fixing buckle is provided at the top of the magnet mounting slot, and a reinforcing rib is provided at the bottom of the magnet mounting slot.

[0008] In a preferred embodiment, the armrest outer cover plate body, the mounting teeth, the upper locking post, the lower locking post and the reinforcing ribs are integrally injection-molded. A high-strength engineering plastic is selected as the material. Multiple special-shaped curved grooves are provided on the armrest outer cover plate body to enhance the bending strength and rigidity of the part, prevent deformation, and reduce the warping deformation caused by internal stress.

[0009] In a preferred embodiment, the magnet block is set as a neodymium iron boron magnet, which has high magnetism and corrosion resistance. The depth of the magnet mounting groove is greater than the thickness of the magnet block.

[0010] In a preferred embodiment, the reinforcing ribs include multiple longitudinal locking rib plates. Among them, the multiple longitudinal locking rib plates are evenly arranged at the bottom of the magnet mounting groove, and upward chamfers are provided at the top ends of the longitudinal locking rib plates. The chamfer angle is 15°-30° to ensure sufficient supporting force and limiting effect on the magnet block.

[0011] In a preferred embodiment, the side connection buckles are symmetrically arranged on both sides of the magnet mounting groove. Anti-slip lines are provided on the inner walls of the side connection buckles. An adjustment groove is opened on the armrest outer cover plate body corresponding to the side connection buckles. The adjustment groove is set as a "C" shape to facilitate the change of the position of the side connection buckles when the magnet block is installed into the magnet mounting groove.

Detailed Implementation

[0021] 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.

[0022] This utility model provides, for example Figure 1-3 The handrail cover assembly shown includes a handrail cover body 1. Mounting teeth 2 and mounting holes 3 are fixedly provided along the outer edge of the handrail cover body 1. An upper locking post 6 and a lower locking post 7 are also fixedly provided on the back side of the handrail cover body 1. Two sets of magnet mounting grooves 4 are provided on the back side of the handrail cover body 1. Magnet blocks are installed in the magnet mounting grooves 4. The magnet blocks are neodymium iron boron magnets, which have high magnetic properties and corrosion resistance. The depth of the magnet mounting groove 4 is greater than the thickness of the magnet blocks. Side connecting buckles 5 are provided on both sides of the magnet mounting groove 4. A top fixing buckle 9 is provided at the top of the magnet mounting groove 4. Reinforcing ribs 10 are provided at the bottom of the magnet mounting groove 4. During the injection molding process... In this design, the reinforcing rib 10 is integrally formed with the handrail outer cover plate body 1, and forms a stable surrounding locking assembly for the magnet mounting groove 4 via the side connecting buckles 5 and the top fixing buckle 9 on both sides. After the magnet block is installed in the magnet mounting groove 4, the reinforcing rib 10 provides upward support for the magnet block, and together with the side connecting buckles 5 and the top fixing buckle 9, it limits the position of the magnet block, ensuring that the magnet block will not loosen or fall off. Compared with the traditional method of using non-woven tape to bond the magnet to the handrail outer cover plate, this method eliminates the need for non-woven tape bonding and increases the thickness of the locking position, strengthening the limiting effect of the magnet mounting groove 4 on the magnet block, and significantly improving the production qualification rate.

[0023] like Figure 3-5, the armrest outer cover plate body 1, the installation engaging teeth 2, the upper locking column 6, the lower locking column 7 and the reinforcing ribs 10 are integrally injection molded. High-strength engineering plastics are selected as the material. Multiple special-shaped curved surface grooves are provided on the armrest outer cover plate body 1 to enhance the bending strength and rigidity of the part, prevent deformation, and reduce the warping deformation caused by internal stress. The installation engaging teeth 2 are positionally engaged with the vehicle body position, and are fixed to the corresponding vehicle body by the upper locking column 6 and the lower locking column 7 to achieve preliminary fixation, and bolts are used to perform rigid locking through the installation holes 3.

[0024] As Figure 3-4 , the reinforcing ribs 10 include multiple longitudinal locking rib plates. Among them, multiple longitudinal locking rib plates are evenly arranged at the bottom of the magnet installation groove 4, and the top of the longitudinal locking rib plate is provided with an upward chamfer, and the chamfer angle is 15°-30° to ensure sufficient supporting force and limiting effect on the magnet block; the side connection buckles 5 are symmetrically arranged on both sides of the magnet installation groove 4, and the inner wall of the side connection buckle 5 is provided with anti-slip lines, and an adjustment groove 8 is opened on the armrest outer cover plate body 1 corresponding to the side connection buckle 5. The adjustment groove 8 is set in a "C" shape to facilitate the position change of the side connection buckle 5 when the magnet block is installed into the magnet installation groove 4.

[0025] The specific implementation method is as follows: The magnet block is installed into the magnet installation groove 4. During this period, the side connection buckle 5 is deformed along the adjustment groove 8 due to the position restriction of the magnet block. After the magnet block is completely installed into the magnet installation groove 4, the side connection buckle 5 is reset to lock the magnet block. The top magnet block is restricted by the position of the top fixing buckle 9. The integrated setting of the reinforcing ribs 10 and the armrest outer cover plate body 1 can support the self-weight of the magnet block by the reinforcing ribs 10, and the high convex chamfer at the top of the reinforcing ribs 10 provides non-elastic supporting and limiting, reducing the use of auxiliary jigs or adhesives, effectively preventing the loosening and abnormal noise of the magnet block caused by the颠簸 of the vehicle when driving with this armrest outer cover plate loaded, and the reinforcing ribs 10 can reduce the injection molding deformation rate of the armrest outer cover plate body 1.
