[0001] The utility model relates to the technical field related to automobiles, in particular to a self-priming lock assembly for an automobile. Background Art
[0002] A car is a car that is powered by power and does not rely on tracks or electricity or mechanical work. In a broad sense, a car that can work by a car is often called a car. Cars can be divided into sedans and commercial vehicles. Sedans are mainly used to transport passengers, their carry-on luggage and temporary items in terms of their design and technical characteristics. Commercial vehicles are used to transport people and goods in terms of design and technical characteristics, and can tow trailers, but do not include sedans. With the development of the automobile industry, consumers' requirements for the convenience of using cars are increasing day by day. Traditional automobile door systems require external force to be applied to the doors to close the car, but the external force is small, and the automobile doors are easily in a semi-locked state. At this time, a greater force is required to fully lock the doors. In order to achieve a transition from semi-locking to fully locking, self-priming door locks have emerged. However, the current self-priming door locks not only have complex transmission structures and poor stability, but also cannot rebound to the initial position to complete the unlocking or locking functions. Therefore, there is a special need for an automobile self-priming lock assembly.
[0003] However, the existing automobile self-priming lock assembly requires greater force to switch from a semi-locked state to a fully locked state, and the transmission structure is complex and the stability is not ideal, and it cannot rebound to the initial position after use.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] See also Figure 1-4 The utility model provides a technical solution: a car self-priming lock assembly, including a base plate 1 and a lock tongue 3, a surface side of the base plate 1 is connected with a locking buckle 2, a surface side of the locking buckle 2 is connected with a lock tongue 3, a surface side of the lock tongue 3 is connected with a first torsion spring 4, a surface side of the lock tongue 3 is connected with a lock head housing 5, a surface side of the lock head housing 5 is connected with a cover plate 6, a surface side of the cover plate 6 is connected with a second torsion spring 7, a surface side of the cover plate 6 is connected with an unlocking linkage torsion spring 8, a surface side of the cover plate 6 is connected with a rivet shaft 9, a surface side of the cover plate 6 is connected with an unlocking linkage rod 10, a surface side of the unlocking linkage rod 10 is connected with an unlocking magnet seat 11, a surface side of the unlocking linkage rod 10 is connected with an unlocking PCBA 12, a surface side of the unlocking linkage rod 10 is connected with a lock head end cable 13, and a surface side of the unlocking PCBA 12 is connected A cable 14 is connected, and a signal harness 15 is connected to one side of the surface of the cable 14. A buffer box 16 is sleeved on one side of the surface of the lock end cable 13, and a lock end cable 17 is connected to one side of the surface of the buffer box 16. The other end of the lock end cable 17 is connected to the lock body 18. When in use, the lock end cable 13 is first pulled, so that the lock end cable 13 drives the unlocking linkage rod 10 to move, and the unlocking linkage rod 10 tends to rotate the lock tongue 3, so that the locking buckle 2 and the lock tongue 3 are changed from a semi-locked state to a fully locked state. When unlocking is required, the unlocking magnet seat 11 is first activated by electric energy, so that the unlocking magnet seat 11 generates magnetic force, so that the unlocking magnet seat 11 drives the lock tongue 3 to move, thereby realizing the function of automatic locking or unlocking. When the child lock is turned on, the car door will not be able to be opened from the inside, thereby avoiding safety accidents caused by children accidentally opening the car door.
[0018] Furthermore, the locking buckle 2 is connected to the lock housing 5, and one end of the first torsion spring 4 is connected to the base plate 1. Through the setting of the locking buckle 2, when in use, the locking buckle 2 and the lock tongue 3 can be snapped together to lock the vehicle door. At the same time, the conversion between half locking and full locking can be achieved through the snapping position with the lock tongue 3.
[0019] Furthermore, the lock tongue 3 is connected to the rivet shaft 9, and the second torsion spring 7 is sleeved on the surface of the locking buckle 2. Through the arrangement of the second torsion spring 7 and the rivet shaft 9, when in use, when the lock tongue 3 moves to squeeze the locking buckle 2, the second torsion spring 7 is squeezed and deformed. When the squeezing force disappears, the second torsion spring 7 starts to reset due to its own characteristics, so that the second torsion spring 7 can provide power for the reset movement of the locking buckle 2, thereby ensuring that the locking buckle 2 and the lock tongue 3 are locked again.
[0020] Furthermore, the lock tongue 3 is connected to the unlocking linkage rod 10, and the unlocking linkage torsion spring 8 is sleeved on the surface of the unlocking linkage rod 10. Through the setting of the unlocking linkage rod 10, when in use, the unlocking linkage rod 10 can drive the lock tongue 3 to move when it is pulled by the lock head end cable 13 or the unlocking magnet seat 11, so that the unlocking linkage rod 10 can provide power for the movement of the lock tongue 3, thereby realizing the conversion between unlocking, half locking and full locking.
[0021] Furthermore, the base plate 1 is connected to the lock shell 5, and the second torsion spring 7 is connected to the lock shell 5. Through the setting of the lock shell 5, when in use, the lock shell 5 can provide support for the locking buckle 2 and the lock tongue 3. At the same time, the lock shell 5 can limit the position of the locking buckle 2 and the lock tongue 3, thereby avoiding the displacement of the locking buckle 2 and the lock tongue 3 and affecting the performance of the self-priming lock.
[0022] Working principle: first pull the lock end cable 13, so that the lock end cable 13 drives the unlocking linkage rod 10 to move, and the unlocking linkage rod 10 drives the lock tongue 3 to rotate, and the lock tongue 3 squeezes the locking buckle 2 to move, and the locking buckle 2 squeezes the second torsion spring 7 to deform. When the locking buckle 2 moves to another slot position of the lock tongue 3, the second torsion spring 7 begins to reset without being subject to external force, so that the second torsion spring 7 drives the locking buckle 2 to reset, thereby changing the locking buckle 2 and the lock tongue 3 from a semi-locked state to a fully locked state. When unlocking is required, first activate the unlocking magnet seat 11 through electric energy, so that the unlocking magnet seat 11 generates magnetic force, so that the unlocking magnet seat 11 drives the lock tongue 3 to move, thereby realizing the function of automatic locking or unlocking. When the child lock is turned on, the car door will not be able to be opened from the inside, thereby preventing children from accidentally opening the car door and causing safety accidents.
[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
