Description

Technical Field

[0001] This utility model belongs to the technical field of automotive skid plate brackets, specifically, it relates to an automotive lower skid plate mounting bracket. Background Technology

[0002] As an important protective component for the bottom of a car, the underbody protection plate can effectively prevent damage to the car chassis from road debris, mud, and water, while also playing a role in sound insulation and noise reduction.

[0003] Utility model CN221023580U discloses an impact-resistant car skid plate bracket, specifically relating to the technical field of car skid plate brackets. This utility model includes a fixing plate, with support plates fixedly connected to both sides of the outer surface of the fixing plate. A first screw hole is formed on the outer surface of the fixing plate, and a second screw hole is formed on the outer surface of the support plates. An auxiliary installation structure is provided on the outer surface of the fixing plate, and an impact-resistant structure is provided on the outer surface of the support plates. The auxiliary installation structure includes a sliding groove. Through the function of the auxiliary installation structure, the car skid plate bracket can be temporarily limited during the installation of the car skid plate, thereby preventing the car skid plate bracket from accidentally falling off when removing nuts, thus avoiding low work efficiency and increased labor costs. The cooperation of the limiting block and the limiting strip allows the original car bolts to be limited by the threads of the original bolts, thereby preventing the car skid plate bracket from falling off.

[0004] However, the aforementioned patents still have the following problems: Existing car skid plate brackets often lack effective auxiliary support structures. During the driving process, especially under complex and changing road conditions, the skid plate brackets are subjected to various impacts and vibrations from the ground. If the brackets do not have sufficient auxiliary support structures to disperse these forces, they are prone to damage and deformation, thereby affecting the protective effect of the skid plate. The length of the device cannot be adjusted, the flexibility of the brackets is reduced, and it is not suitable for the installation of lower skid plates on different car models, thus limiting the use of the device.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0039] Working Principle: This automotive underbody protection plate mounting bracket mainly consists of a first bracket 10, an adjustment structure, and several fixing and connecting components. The first bracket 10 serves as the main structure, providing the foundation for supporting and fixing the underbody protection plate. The adjustment structure, through the cooperation of a first adjustment part and a second adjustment part, allows for flexible adjustment of the bracket length to adapt to the underbody protection plate installation requirements of different vehicle models. The first adjustment part of the adjustment structure includes a second bracket 14, a second protective pad 15, a first sliding groove 16, and a first damping spring rod 17. The second bracket 14 is fixedly installed on one side of the first bracket 10, and the first sliding groove 16 inside provides a track for the sliding of the slider 21. One end of the first damping spring rod 17 is fixed to the inner wall of one side of the sliding groove, and the other end is fixedly connected to the outer side of one side of the slider 21, providing elasticity and support for the slider 21. When the bracket length needs to be adjusted, the second fixing plate 22 can be pulled, causing the first fixing plate 20 and the slider 21 to slide within the first sliding groove 16. The first damping spring rod 17 provides corresponding support force according to the sliding distance, ensuring the stability and firmness of the bracket. The second adjustment section includes components such as a limiting hole 18, a third fixing plate 23, a first connecting plate 24, a second threaded groove 25, and a second limiting bolt 26. By pulling the third fixing plate 23, the second fixing plate 22 and the second adjustment section can be moved as a whole, thereby further adjusting the length of the bracket. The second threaded groove 25 and the second limiting bolt 26 on the first connecting plate 24 are used to fix the adjusted bracket length to prevent loosening or displacement during use. The first bracket 10 is also provided with components such as a first threaded groove 11, a first protective pad 12, a third protective pad 19, and a first limiting bolt 13 for fixing the bracket to the vehicle chassis. The first protective pad 12 and the third protective pad 19 provide cushioning and protection, protecting the bracket and the vehicle chassis from damage. At the bottom of the bracket, there are also components such as a cover plate 36, a pull strap 37, and a rubber block 38 for covering and fixing the first limiting bolt 13, while providing additional support and stability. The bottom of the second bracket 14 is provided with components such as a first snap-fit ​​groove 27, a third spiral groove 28, a second connecting plate 29, a fourth threaded groove 30, and a third limiting bolt 31, which are used to connect and fix the second bracket 14 to the first bracket 10 or other fixing components. Components such as a fourth fixing plate 32, a fifth fixing plate 33, a fifth threaded groove 34, and a fourth limiting bolt 35 are used to fix the bracket to the bottom of the car's lower guard plate to ensure a tight connection and stability between the lower guard plate and the bracket.
