Problems solved by technology

When a collision lower than the self-locking opening threshold occurs, the handle turns due to inertia or deformation of the door sheet metal. Since the handle body is connected to the door lock control device, when the handle body rotates, the door lock control device is activated, causing the door to lock. The control lever of the lock rotates to open the door, but at this time the inertial locking block cannot play its intended role due to insufficient collision threshold, causing the door to be opened accidentally, which brings danger to the occupants of the car.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] see Figure 1-7 As shown, a car door collision self-locking structure includes a handle bracket body 1 and a door lock control device 2 arranged thereon. The car door lock control device 2 controls the lever 21 to rotate up and down. , when the door handle is turned, the control lever 21 turns downward to open the door, there is a torsion spring force between the door handle and the door control device 2, only when the external force overcomes the torsion spring force between the door handle and the door lock control device 2 , the control rod 21 will rotate downwards, and when the external force disappears, the control rod 21 will reset immediately. The handle bracket body 1 is provided with an installation frame 11 , and the self-locking control device 3 is installed in the installation frame 11 , and the outer end of the control rod 21 is located in front of...

Abstract

The invention relates to a collision self-locking structure of a car door opening handle, which comprises a handle bracket body and a door lock control device arranged on it. The car door lock control device controls the up and down rotation of a control rod. A self-locking control device is installed in the frame. The invention can avoid accidental opening of the car door caused by excessive collision threshold of the collision self-locking structure during the side collision of the automobile.

Description

technical field [0001] The invention relates to a car door component, in particular to a collision self-locking structure of a car door opening handle. Background technique [0002] Existing locking structure with anti-collision door opening by mistake, such as a lock mechanism disclosed by CN203230233U for preventing serial impact inertia mistaken door opening, generally includes inertial locking block, balance return block and torsion spring, which triggers collision acceleration The threshold value is larger, and the collision acceleration lower than the threshold value will not cause the door to be locked. When a collision lower than the self-locking opening threshold occurs, the handle turns due to inertia or deformation of the door sheet metal. Since the handle body is connected to the door lock control device, when the handle body rotates, the door lock control device is activated, causing the door to lock. The control lever of the lock rotates to open the door, but ...
