[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings:

[0023] To facilitate understanding of this utility model, a detailed description is provided below with reference to the accompanying drawings. It should be noted that the dimensions and shapes of the various components shown in the drawings are for reference only and do not constitute a limitation on the scope of protection of this utility model.

[0024] like Figures 1-5 As shown, this utility model provides an installation structure for a car underbody protection plate, mainly including a connecting system mounted on the underbody and a support system for supporting the underbody protection plate 5. The connecting system includes two parallel longitudinal beams of the underbody, which serve as the main load-bearing structures to ensure the stability of the entire installation structure. Each longitudinal beam of the underbody is equipped with a connector 1, which is made of high-strength alloy material to provide sufficient structural strength. Each connector 1 has a precisely machined positioning groove 2. The size and shape of the positioning groove 2 are optimized to ensure installation accuracy and facilitate assembly. The connector 1 can be a sheet metal part with a positioning groove 2 that matches the mounting bracket 3, and it can be similar to an Ω shape.

[0025] The core component of the support system is the mounting bracket 3, which extends along the width of the vehicle body and connects the gap between the two connectors 1. The mounting bracket 3 adopts a circular tube structure design, which not only provides excellent load-bearing capacity but also effectively reduces overall weight. Specifically, the mounting bracket 3 comprises three main parts: a first horizontal circular tube section 31, an inclined circular tube section 32, and a second horizontal circular tube section 33. The first horizontal circular tube section 31 is symmetrically arranged on both sides of the second horizontal circular tube section 33; this symmetrical arrangement ensures uniform load distribution. The first horizontal circular tube section 31 and the second horizontal circular tube section 33 are connected by the inclined circular tube section 32, forming a stable triangular structure that effectively transmits and disperses stress.

[0026] On the mounting bracket 3, especially on the second horizontal circular pipe segment 33, a plurality of connecting plates 4 are arranged along the vehicle body width direction. These connecting plates 4 are in the form of cubic flat pieces, and are made of corrosion-resistant and high-strength metal materials. Each connecting plate 4 is designed with connecting holes, and the arrangement of these connecting holes is accurately calculated to ensure complete correspondence with the mounting hole positions of the bottom guard plate 5. The connecting plates 4 and the second horizontal circular pipe segment 33 are fixed by welding, and the welding process needs to be strictly controlled to ensure that the quality and strength of the weld meet the use requirements.

[0027] The bottom guard plate 5 and the connecting plate 4 are connected by rivets, which has the characteristics of simple operation, easy disassembly and reassembly, and can also ensure the reliability of the connection. The selection of rivets needs to consider the matching and durability of the material, and high-strength rivets with rust-proof treatment are usually used. The first horizontal circular pipe segment 31 and the mounting bracket 3 are also connected by welding, and the welding position and weld size need to be strictly executed according to the process requirements.

[0028] In terms of fixing the entire installation structure, the mounting bracket 3 and the vehicle body lower body longitudinal beam are connected by bolts. This connection method is not only convenient to install, but also convenient for later maintenance and replacement. The selection of bolts needs to consider the strength grade and anti-loosening requirements, and appropriate anti-loosening devices such as spring washers or lock nuts should be provided.

[0029] In the actual installation process, first, the connecting piece 1 is fixed on the vehicle body lower body longitudinal beam to ensure the accurate position of the connecting piece 1. Then, the mounting bracket 3 is placed in the positioning groove 2, and its position is adjusted to completely match the positioning grooves 2 on both sides. After positioning is completed, the mounting bracket 3 is firmly connected with the vehicle body lower body longitudinal beam by bolts. Finally, the bottom guard plate 5 is fixed on the connecting plate 4 by rivets, and the fastening condition of all connecting points is checked to ensure that the entire installation structure is stable and reliable.

[0030] The materials and sizes of the various components in this embodiment can be selected as needed, and the connection method can also be adjusted appropriately under the premise of ensuring the installation strength. The entire installation structure is designed reasonably, compactly and conveniently, and can well meet the installation requirements of the automobile bottom guard plate.

[0031] It should be noted that the above embodiments are only preferred embodiments of the present application, and are not used to limit the protection scope of the present application. Those skilled in the art can make various modifications and improvements to the present application without departing from the concept and principle of the present application, and these modifications and improvements should fall within the protection scope of the present application. For example, the cross-sectional shape of the protective cross beam 2 can be circular, oval, rectangular or other appropriate shapes; the specific structure of the connecting piece 1 can also be adjusted according to actual needs; the specific arrangement of the bottom guard plate mounting assembly can also be changed according to the structure requirements of the whole vehicle.

[0032] It should be understood that those skilled in the art can improve or change according to the above description, and all these improvements and changes should belong to the protection scope of the appended claims of the present application.
