Problems solved by technology
In the event of a collision, if the hood is fully locked, there is little cushion between the hood and these hard points, which can cause significant injury to pedestrians
[0003] Further, the inventor found that for a vehicle equipped with a pedestrian airbag, when the vehicle collides, the pedestrian airbag is deployed from the rear end of the hood, if only the rear end of the hood is lifted and the front end of the hood is completely locked, The gap at the rear end of the hood is small, which is not conducive to the full deployment of the pedestrian airbag, and there is room for improvement

The invention discloses a locking device for an engine hood and a vehicle. The locking device comprises a lock pin, a bottom plate, a first locking piece, a second locking piece and a driving piece. A primary latch hook is arranged on the second locking piece. The driving piece can move relative to the bottom plate and comprises a first driving part and a second driving part. The first driving part is suitable for driving the first locking piece to enable the first locking piece and the second locking piece to be unlocked. After the first locking piece and the second locking piece are unlocked, the second driving part is suitable for driving the second locking piece to enable the lock pin to be separated from the primary latch hook. When at least a part of the second locking piece is driven by the second driving part, the first locking piece is not driven by the first driving part. By means of the locking device for the engine hood, disclosed by the invention, damage to the bottom plate or other parts, which is caused by too long stroke of the first driving part, can be avoided, and primary locking of the engine hood can be rapidly removed through the locking device.
Description
technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a locking device for a hood and a vehicle provided with the locking device. Background technique [0002] The hood is usually located on the front side of the vehicle and is used to cover the engine compartment, and when the hood is fully locked, there is less clearance between the hood and a hard point under the hood, such as the bodywork. In the event of a collision, if the hood is fully locked, there is less cushion between the hood and these hard points, which can cause more injury to pedestrians. [0003] Further, the inventor found that for a vehicle equipped with a pedestrian airbag, when the vehicle collides, the pedestrian airbag is deployed from the rear end of the hood, if only the rear end of the hood is lifted and the front end of the hood is completely locked, The gap at the rear end of the hood is small, which is not conducive to the full...
