Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile accessories, and in particular relates to an anti-lifting automobile engine cover. BACKGROUND

[0002] The automobile engine cover, as an important cover in the front part of the vehicle, its main function is to protect the components in the engine compartment from external environmental interference. At present, most of the automobile engine covers on the market are fixed by simple mechanical locks, usually including a main locking hook and a corresponding lock catch mechanism. These locks can keep the engine cover closed under normal circumstances, but in some cases, such as high-speed driving or slight collision, there may be safety hazards. With the continuous improvement of automobile safety standards, the locking system of the engine cover needs to be more reliable and intelligent.

[0003] The engine cover lock of the prior art often relies on a single-point locking mechanism, which is simple in structure but weak in impact resistance. When the vehicle experiences severe vibration or collision, the lock catch is easily accidentally detached due to inertial force, causing the engine cover to be lifted, obstructing the driver's view and even causing secondary accidents. In addition, the unlocking process of the traditional lock may not be intuitive, and multiple people or special tools are needed for maintenance, increasing the maintenance cost and time. Some designs lack double insurance and cannot ensure safety under extreme conditions, limiting their application range; therefore we propose an anti-lifting automobile engine cover to solve this problem.
