Description

Technical Field

[0001] The utility model relates to the technical field of automobile chassis protection devices, and more particularly to an automobile chassis protection device. Background Art

[0002] In existing automotive underbody protection systems, the installation process for protective panels is often inconvenient. Because the protective panels need to be fixed to a specific location on the vehicle chassis, existing installation methods can require complex steps, such as adjusting the position, aligning holes, and securing with screws. This cumbersome installation process is not only time-consuming and error-prone, but also requires a high level of skill and patience. Consequently, this inconvenient installation method can lead to unstable installation of the protective panels, even compromising their protective effectiveness.

[0003] Furthermore, the inconvenience of installation also impacts the removal process of the fender. When repairing or replacing chassis components, the fender must be removed first. However, due to potential misalignment or loose fastening during installation, removal can be difficult and may even damage the fender or chassis components. This inconvenience not only increases repair costs and time but can also cause additional damage to the vehicle's chassis. Therefore, the installation and removal process of existing chassis guards is challenging for both users and maintenance personnel, impacting the device's practicality and durability.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a vehicle chassis protection device with the following features:

[0017] Beneficial effects:

[0018] 1. The design of the disassembly mechanism makes the installation and disassembly process of the automobile chassis protection device more convenient. Through the cooperation of the protective sleeve, the outer sleeve and the fixing sleeve, the quick installation of the protective plate is realized. When fixing, the spring applies thrust to make the push ring contact with the protective plate, and the one-way block is stuck on the one-way sleeve to form a self-locking function, thereby ensuring the fixation of the protective plate. At the same time, the indicator rod fits on the scale to display the position of the slider, thereby displaying the strength of the clamping. This design not only simplifies the installation steps, but also improves the convenience of operation, providing users with a more efficient use experience.

[0019] 2. The clamping mechanism realizes the adjustment of the clamping force through the configuration of the shrink sleeve and the slider. Multiple sliders are respectively provided with one-way blocks, which are clamped on the one-way sleeve. The position of the slider can be adjusted by the action of the push spring, thereby changing the clamping force. This design not only improves the flexibility of the clamping, but also can adapt to the fixing requirements in different situations, thereby enhancing the applicability of the equipment.

[0020] 3. The rotating mechanism realizes the fixation and adjustment of the spring through the configuration of the thrust bearing and the reducing sleeve. By rotating the rotating sleeve, the reducing sleeve contacts the top block, thereby driving the spring to be compressed and realizing the fixation of the spring. When it needs to be released, only the reducing sleeve needs to be rotated to release the connection between the two. This design not only improves the flexibility of adjustment, but also avoids complicated operating steps, providing convenience for the use of automobile chassis protection devices.
