Description
Technical Field
The utility model relates to the technical field of automobile locks, in particular to a door lock assembly structure with a gear transmission structure.
Background
The automobile door lock is used as an important safety accessory and plays a role in connecting door metal plates and side door locking blocks in the automobile side door. Because of the difference of the installation positions of the automobile door lock and the side door locking piece, the connection modes of the automobile door lock and the side door locking piece are mainly divided into three types: 1, the side door lock block is directly matched and connected with a transmission paddle on a side door lock; 2, the transmission piece on the door lock is matched and connected with the side door locking piece; and 3, the eccentric arm on the automobile door lock, the clamping sleeve and the pull rod on the side door locking block are matched and connected.
For the lock core of the first type of automobile door lock, a certain distance between the central axis of the lock core and the axis of the side door locking piece is generally required, and when the distance is exceeded, the lock core cannot effectively transmit torque to the side door locking piece, so that the automobile door lock is invalid, and therefore, certain limitation exists in use.
Disclosure of Invention
The utility model aims to solve the technical problem of providing an automobile door lock assembly structure with a gear transmission structure, which overcomes the limitation of the assembly of a traditional lock cylinder and a side door locking piece aiming at the distance, effectively solves the assembly problem of larger distance, ensures the transmission torque between the lock cylinder and the side door locking piece and avoids the failure of the automobile door lock.
In order to solve the technical problems, the automobile door lock assembly structure with the gear transmission structure comprises a shell, a sealing cover, a lock cylinder and a transmission paddle, wherein the lock cylinder is installed in the shell, the sealing cover is arranged on the top surface of the shell, the automobile door lock assembly structure also comprises a gear box cover, a transmission ring, a driving gear and a driven gear, the gear box cover is arranged on the bottom surface of the shell, the driving gear and the driven gear are arranged in the gear box cover and meshed with each other, the driving gear is connected with the lock cylinder through the transmission ring, a rotating shaft is arranged at the center of the driven gear and extends out of the gear box cover, and the transmission paddle is connected with the rotating shaft through a pin.
Further, the assembly structure further comprises a sealing ring, and the sealing ring is arranged between the sealing cover and the shell.
Further, the driving gear and the transmission ring are sleeved into the bottom end of the lock cylinder and fixed by adopting a split washer.
The automobile door lock assembly structure with the gear transmission structure adopts the technical scheme that the automobile door lock assembly structure comprises a shell, a sealing cover, a lock cylinder and a transmission paddle, wherein the lock cylinder is arranged in the shell, the sealing cover is arranged on the top surface of the shell, the automobile door lock assembly structure further comprises a gear box cover, a transmission ring, a driving gear and a driven gear, the gear box cover is arranged on the bottom surface of the shell, the driving gear and the driven gear are arranged in the gear box cover and meshed with each other, the driving gear is connected with the lock cylinder through the transmission ring, a rotating shaft is arranged at the center of the driven gear and extends out of the gear box cover, and the transmission paddle is connected with the rotating shaft through a pin. The assembly structure overcomes the limitation of the assembly of the traditional lock cylinder and the side door locking piece aiming at the space, effectively solves the assembly problem of the large space, ensures the transmission torque between the lock cylinder and the side door locking piece, and avoids the failure of the automobile door lock.
Drawings
The utility model is described in further detail below with reference to the attached drawings and embodiments:
FIG. 1 is a schematic view of an assembly structure of an automobile door lock with a gear transmission structure according to the present utility model;
fig. 2 is a cross-sectional view of fig. 1.
Detailed Description
Embodiment as shown in fig. 1 and 2, the automobile door lock assembly structure with the gear transmission structure of the utility model comprises a shell 1, a sealing cover 2, a lock cylinder 3 and a driving paddle 4, wherein the lock cylinder 3 is installed in the shell 1, the sealing cover 2 is arranged on the top surface of the shell 1, the automobile door lock assembly structure also comprises a gear box cover 5, a transmission ring 6, a driving gear 7 and a driven gear 8, the gear box cover 5 is arranged on the bottom surface of the shell 1, the driving gear 7 and the driven gear 8 are arranged in the gear box cover 5 and meshed with each other, the driving gear 7 is connected with the lock cylinder 3 through the transmission ring 6, a rotating shaft 81 is arranged in the center of the driven gear 8 and extends out of the gear box cover 5, and the driving paddle 4 is connected with the rotating shaft 81 through a pin 41.
Preferably, the assembly structure further comprises a sealing ring 11, and the sealing ring 11 is arranged between the sealing cover 2 and the shell 1. To ensure a seal of the housing cavity in which the lock cylinder is mounted.
Preferably, the driving gear 7 and the transmission ring 6 are sleeved into the bottom end of the lock cylinder 3 and fixed by adopting a split washer 9.
In the starting process of the automobile door lock, the driving ring and the driving gear are driven to rotate through the rotating lock cylinder, the driving gear is meshed with the driven gear and rotates to drive by means of the gear structure, the driven gear drives the transmission oar at the bottom to rotate, and finally the rotating angle of the transmission oar is transmitted to the side door locking piece, so that the opening of the automobile door is realized.
Because this assembly structure adopts driving gear and driven gear engaged gear transmission lock core's moment of torsion to driving oar, and the moment of torsion of driving oar transmits to the side door locking piece, designs corresponding driving gear and driven gear according to lock core central axis and side door locking piece axis interval to ensure the transmission of moment of torsion, overcome traditional lock core and side door locking piece assembly and to the restriction of interval, effectively solve the bigger assembly problem of interval, ensure the transmission moment of torsion between lock core and the side door locking piece, avoid car lock to become invalid.
