[0002] At present, the methods for fixing the threshold guard plate to the body sheet metal include:
[0003] 1. A mounting bracket is set on the floor of the body sheet metal, and a hole is opened, and the door sill guard is directly bolted from the outside. Disadvantages: The bolt head is exposed and needs to be covered by a carpet. This fixing method cannot be used in places without carpets, and the application scenarios are limited.
[0004] Second, the floor of the body sheet metal is first assembled with the wiring harness card, and the threshold guard is then connected to the wiring harness card to achieve fastening with the floor. Disadvantages: The wiring harness card has a complex structure, and it is impossible to observe and align it during installation. It is difficult to install and disassemble, and it is easy to damage the product.
[0005] 3. The floor opening of the body sheet metal and the door sill guard are assembled through D-type buckles. Disadvantages: D-type buckles require a larger base and are suitable for models with higher chassis such as MPV / SUV. The models are limited, and the floor opening of the body sheet metal requires waterproof D-type buckles, which has the risk of water leakage.
[0006] When the conditions of the body sheet metal limit and it is impossible to drill holes, the above-mentioned conventional bolt connection, wiring harness clip connection, and waterproof D-type clip connection cannot be used, and the body floor of the above connection methods requires drilling holes and waterproofing.
