[0002] The unlocking of the car hood is usually achieved by a fixed bracket, an operating handle and a pull wire. The fixed bracket is used to install the operating handle on the guard plate. By pulling the operating handle, the pull wire can be driven to unlock the car hood. At present, the fixed bracket on the car is usually a metal part processed by sheet metal, which has the problems of heavy weight, cumbersome installation and easy to make abnormal noise during operation. Summary of the invention

[0003] The utility model aims to provide an unlocking driving device for a car engine hood, which is lighter in weight, simpler to install and does not make abnormal noise when working.

[0004] The utility model provides an unlocking driving device for a car engine hood, comprising a guard plate, a plastic bracket, an operating handle and an elastic reset member. The guard plate can be fixed inside the car. The plastic bracket is fixed to the guard plate by snapping. The operating handle is movably arranged on the plastic bracket between an initial position and an unlocking position, and the locking device of the car engine hood can be driven during the movement of the operating handle from the initial position to the unlocking position. The elastic reset member applies an elastic restoring force to the plastic bracket and the operating handle to drive the operating handle to move toward the initial position.

[0005] The unlocking drive device of the automobile engine hood provided by the utility model is fixed to the guard plate by a plastic bracket in a clamping manner, replacing the fixing bracket processed by sheet metal. The plastic bracket is lighter in weight, simpler to install, and will not make abnormal noise even if it is slightly deformed during operation.

[0006] In another schematic embodiment of the unlocking drive device of the automobile hood, a mounting hole and a sliding hole are formed on the guard plate, the sliding hole extends along a mounting direction and one end of the sliding hole is connected to the mounting hole, and the width of the mounting hole in a direction perpendicular to the mounting direction is greater than the width of the sliding hole.
