Description

Technical Field

[0001] This utility model belongs to the technical field of motorcycle parts, specifically relating to an engine protective baffle and its installation structure. Background Technology

[0002] As we all know, the engine is a crucial component of a motorcycle. However, existing motorcycle engines are exposed on the chassis without any protection. If a rider encounters a sharp, large rock while riding on uneven ground, the engine can easily be damaged. In addition, the engine often generates a lot of heat when it is running, causing its surface temperature to be high. If a child touches the bottom of the motorcycle or an animal passes under the engine immediately after it stops, it can easily cause burns.

[0003] Therefore, a motorcycle engine protective cover, with announcement number "CN203094280U", includes a protective cover installed at the bottom of the engine. The protective cover has a front mounting bracket and a rear mounting bracket at its front and rear ends, respectively. The front mounting bracket is connected to the motorcycle frame, and the rear mounting bracket is connected to the motorcycle engine. This utility model connects the front end of the protective cover to the motorcycle frame via the front mounting bracket and the rear end of the protective cover to the motorcycle engine via the rear mounting bracket. It utilizes the original bolt mounting positions on the motorcycle for positioning and installation, making installation more convenient. Furthermore, the bolt connection provides a more reliable connection, preventing the protective cover from detaching during a collision. The structure is simple and low-cost, effectively preventing impacts from the bottom of the motorcycle to the engine, and also effectively preventing burns caused by children or animals touching the bottom of the engine.

[0004] However, although the aforementioned motorcycle engine cover connects the front end of the cover to the motorcycle frame via a front mounting bracket and the rear end to the motorcycle engine via a rear mounting bracket, allowing for convenient installation using the original bolt mounting positions on the motorcycle, it still has the following significant drawbacks during use: While the cover can be installed quickly, it only protects the front of the motorcycle engine and cannot protect the two sides of the engine when the motorcycle tilts to one side, thus causing damage to the engine when it tilts to one side.
