Abstract
The utility model discloses a lock cylinder structure of an automobile door. The lock cylinder structure of the automobile door comprises a lock casing, a lock cylinder which is arranged in the lock casing, a locking blade, a locking spring and a swing arm which rotates along with the lock cylinder. The locking blade and the locking spring which are matched in unlocking are arranged in the lock cylinder. One end of the swing arm is connected with the lock cylinder and the other end of the swing arm is matched with a lock body on the automobile door. A lower shoulder is arranged on the lock cylinder and a boss is arranged on an end portion, where the swing arm is matched with the lock cylinder, of the lock cylinder. The boss is pressed on the lower shoulder. A rubber gasket is arranged between the swing arm and the lock cylinder to reduce noise from movement. The lock cylinder structure of the automobile door is simple in structure and reduces investment in design and cost due to the fact that motion simulation and journey verification are required in designing the swing arm and the length of the swing arm can be directly measured out. The rubber gasket can assist in forming certain pre-pressure between two parts on the one hand and prevent metal collision and consequential noise in vibration on the other hand. The lock cylinder structure of the automobile door can be widely applied in the field of locks of automobile doors.
Description
Technical field
The utility model relates to a kind of lock core structure, relates in particular to a kind of automobile door lock cored structure.
Background technology
The automobile door lock cored structure typically uses drive block and shaft coupling and is connected with pull bar on the lock body and realizes that open locking, the movement travel of drive block need guarantee open locking normal operation after analog computation, and it is long to calculate the check time, the precision prescribed height.A kind of Novel automobile door lock cylinder is disclosed such as Chinese patent application numbers 201020596068.8, comprise lock core, pellet group, clutch cover, connecting piece, transmission slurry, driver blade, stage clip, torsion spring, driver blade is that cam is connected with clutch cover, and stage clip is positioned at below the driver blade.The utility model can be protected lock core and antitheft.But this structure do not explain transmission slurry with the concrete annexation of car door lock body, and do not have elastic component between transmission slurry and lock core, intermetallic contacts with each other, and easily produces noise and wearing and tearing.
The utility model content
The purpose of this utility model provides a kind of automobile door lock cored structure, solves drive block and is connected stroke check complexity with the car door lock body with shaft coupling, and the problem that the part requirement precision is high solves the large problem of metal friction noise between lock core and driving member simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of automobile door lock cored structure, comprise lock housing, and be arranged on the lock core in the lock housing, be arranged on lock blade and the lock leaf spring of the cooperation release in the lock core; Also be provided with the swing arm of rotating together with lock core, swing arm one end links to each other with lock core, and other end lock body direct and on the car door cooperates.
Further, be provided with heavy shoulder on the described lock core, the end that swing arm cooperates with lock core is provided with boss, and boss is pressed on the heavy shoulder.
For reducing motion artifacts, also be provided with rubber pad between described swing arm and the lock core.
For preventing that dust from falling in the lock core, in keyhole corresponding to described lock core, be provided with protective cover, protective cover is connected with rotating shaft on being fixed on lock core, also is provided with the torsion spring of protective cover reset response in rotating shaft.
The beneficial effects of the utility model: lock body direct by swing arm and on the car door cooperates realizes unlocking function, transmission is more direct, and does not need to carry out motion simulation and stroke check when design, can draw the length of swing arm by direct measuring, reduce design and drop into, reduce cost.Rubber pad realizes that on the one hand certain precompressed is arranged between two parts, can not cause on the other hand the intermetallic collision to produce noise in the vibrations process.Described dust cap can prevent falling into of the interior dust of lock core and foreign matter, affects the application life of lock core.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Description of drawings
Fig. 1 is sectional view of the present utility model.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of automobile door lock cored structure comprises lock housing 5, is arranged on the lock core 3 in the lock housing 5, is arranged on lock blade 6 and the lock leaf spring 7 of the cooperation release in the lock core 3; Also be provided with the swing arm 1 of rotating together with lock core 3, swing arm 1 one ends link to each other with lock core 3, and other end lock body direct and on the car door cooperates.Be provided with heavy shoulder 31 on the lock core 3, the end that swing arm 1 cooperates with lock core 3 is provided with boss 11, and boss 11 is pressed on the heavy shoulder 31.Between swing arm 1 and lock core 3, also be provided with rubber pad 2.Cooperate the realization unlocking function by swing arm 1 lock body direct and on the car door, transmission is more direct, and does not need to carry out motion simulation and stroke check when design, can draw the length of swing arm 1 by direct measuring, reduces and designs input, reduces cost.Rubber pad 2 realizes between lock core 3 and the swing arm 1 certain precompressed being arranged on the one hand, can not cause on the other hand the intermetallic collision to produce noise in the vibrations process, improves client to the satisfaction of product.
Be provided with protective cover 12 in the keyhole of lock core 3 correspondences, protective cover 12 is connected with rotating shaft 4 on being fixed on lock core 3, also is provided with the torsion spring 10 of protective cover 12 reset responses in rotating shaft 4.When key inserted, protective cover 12 upsets were stepped down, and key is extracted rear defence protecting cover 12 and realized that upset resets, and prevents that dust and foreign matter from falling into lock core, affects the application life of lock core; Also be fixedly connected with lock core cover 9 in lock core 3 ends, be provided with lock housing cover plate 8 in the end of lock housing 5, be provided with the hole of matching with key at lock core cover 9 and lock housing cover plate 8.
