Why doesn't the hood pop open when released?

Lock tooth spring lacks lubrication, just add a little lubricating oil. Introduction to the engine hood: The engine hood (also known as the bonnet) is the most prominent body component and one of the parts that car buyers frequently inspect. The main requirements for an engine hood are heat and sound insulation, lightweight construction, and high rigidity. Principle of the engine hood: When opening, the engine hood usually flips backward, though a small portion flip forward. A backward-flipping hood should open to a predetermined angle without contacting the windshield, maintaining a minimum gap of about 10 millimeters. To prevent accidental opening during driving due to vibration, the front end of the engine hood is equipped with a safety lock hook mechanism. The lock release switch is located under the dashboard inside the cabin. When the doors are locked, the engine hood should also be simultaneously locked.
