Background

The automobile is a tool of riding instead of walk that people often use in daily life, and the automobile is intelligent and electronized gradually, uses more comfortable convenient, experiences sense greatly increased, and electronic information technology's security is constantly strengthened, and electronic control opens the door and is a novel car lock, and mechanical structure is simple compact, has fine development prospect.

Along with consumers ' demand to car intellectuality, convenience, whole car is for inside sound insulation effect is good, and sealed effect has improved by a wide margin than before, and sealing force increases thereupon, and electronic release side door lock begins to be applied to market, is along with electronic technology's development, and it is to the change of each part control mode of car door to open, makes the control of car door become more automatic, ensures personal safety, has increased user's experience and the convenience of opening and shutting the door.

At present, when a side door lock of an automobile in the market is closed, after a ratchet wheel rotates to a certain angle, a pawl clamps the ratchet wheel under the action of a spring, so that the locking effect is achieved. In cold winter, the vehicle door and the vehicle door lock can be frozen to be frozen, the vehicle door is often frozen to cause that the ratchet wheel cannot return naturally, and meanwhile, the sealing strip is hardened and the sealing force is increased; the door opening and closing are affected, sometimes the door is not closed, and sometimes the door is not released by electric power.

The device for assisting in opening and closing the door through the single stay wire is an auxiliary mechanism for opening and closing the door, and can solve the defect that the door cannot be closed due to the increase of sealing force, and the door lock are frozen and cannot be electrically released; the auxiliary door opening is often termed icebreaking and the auxiliary door closing is often termed self-priming.

The door lock structure for realizing the self-priming and ice breaking functions of the door lock, which is common in the automobile industry at present, mainly comprises the following components:

When the ice is required to be broken, the ice breaking pull wire of the actuator drives the mechanical structure in the door lock, so that the door is opened. The door lock realizes the self-priming and ice breaking functions of the door lock, but needs double stay wire actuators, and has higher cost.

2) Self-priming door lock, single-stay wire actuator and electric auxiliary ice breaking mechanism

The door lock can only cooperate with the actuator to complete the self-priming function, does not have the ice breaking function, needs to additionally add an auxiliary mechanism to break ice, improves the space requirement on the door sheet metal, increases the complexity of the mechanism and increases the cost.

3) Self-priming door lock and single-stay wire actuator

The door lock system is simple, can only realize the self-absorption of door lock, does not possess the function of breaking ice, can't adapt to the motorcycle type of electric door.

The Chinese patent with the publication number of CN 115807592A discloses an electric automobile side door lock with a self-priming function, which comprises a lock body and a shell, wherein an electric self-opening mechanism is arranged on the shell, a self-priming mechanism and an ice breaking mechanism are arranged on the lock body, when a vehicle door is automatically or manually closed to a half-locking state, a ratchet wheel is engaged with a pawl in a first gear, the self-priming mechanism is assisted to realize the self-priming function under the condition that the vehicle door of the self-priming mechanism is not completely closed through a self-priming inhaul cable and a related mechanism, and the ice breaking mechanism is assisted to realize the ice breaking door opening under the condition that the vehicle door is not opened through the ice breaking inhaul cable and the related mechanism.
