Embodiment 1

[0040] Such as image 3 , 4 , 5, and 7, the spare tire cover is divided into a fixed part and an overlapping part. The substrate material of the fixing part is PHC, and the material of the overlapping part is thermoplastic material. A thermoplastic embedded part is provided at the front end of the base plate of the fixed part, and the thermoplastic embedded part is not covered when covering the fabric. The overlapping part and the thermoplastic embedded part on the base plate of the fixed part are connected together by welding.

[0041]The embedded part on the base plate of the fixed part is a thermoplastic sheet, more specifically, it can be a PP sheet, but the surface energy of the PP sheet itself is too low, and it is not easy to be compatible with the polyurethane foam of the PHC cover, so it needs to be placed on the surface (at least the lower surface) corona or plasma treatment in advance. Of course, you can also apply a primer on the surface of the PP sheet, but th...

Embodiment 2

[0050] like Figure 4 , 5 , 7, a groove is provided at the rear boundary of the embedded part on the PHC substrate of the fixed part. This kind of PHC substrate with grooves is also very simple to produce, as long as a convex edge is set on the mold and the draft angle is considered. Moreover, this convex rib can also serve as a limit function when placing PP embedded parts, so that the position of thermoplastic embedded parts is more consistent, and the subsequent fabric compounding and lap joint assembly operations will be more convenient.

[0051] The advantage of this groove is that when attaching the fabric to the PHC substrate, the edge of the fabric can be stuffed into the groove, so as to avoid the exposure of broken stubble and affect the appearance. Figure 4 shown. Of course, the groove can also be made wider, and the broken stubble of the PP sheet can also be stuffed into the groove. Figure 7 shown. However, the PP sheet is very hard, and the edge treatment n...

Abstract

The invention relates to a spare tire cover plate and a production method thereof. The spare tire cover plate is provided with a fixing part and a lap joint part, and is characterized in that a base plate of the fixing part is made of PHC materials, a thermoplastic embedded part is arranged at the front end of the base plate of the fixing part, the lap joint part is made of thermoplastic materials, and the lap joint part and the thermoplastic embedded part on the base plate of the fixing part are connected together in a welding mode. According to the scheme, the structure is simple, productionis convenient, the cost is low, the lap joint part has enough stiffness and a good turnover effect, and the problem of a gap formed after the SUV type seat is turned over forwards is effectively solved.

Description

technical field [0001] The application relates to a spare tire cover plate and a production method thereof. Background technique [0002] The spare wheel cover is a car interior on SUV models, which is placed on top of the spare wheel to provide a flat storage space. Generally, it is required to have better load-bearing capacity. At present, the most commonly used material is glass fiber reinforced polyurethane material with honeycomb paper sandwich, referred to as PHC. The advantage of this material is that it has a hollow structure, light weight and good rigidity. [0003] In order to increase storage space, the rear seats of SUV models can be folded forward. At this time, there will be a gap between the spare tire cover and the seat, and small items are easy to slip off, so the spare tire cover is usually provided with a movable part that is in contact with the seat to cover the gap. [0004] A common solution is that the spare wheel cover is divided into two pieces, o...
