A double-pull structure for inner opening of automobile side door lock

Abstract

The present invention discloses an inner opening double-pull structure for a car side door lock, comprising a main body, a motor fixedly connected to the back of the main body, a worm fixedly connected to the output end of the motor through a coupling, and a double gear rotatably connected to the right side of the main body. The present invention relates to the technical field of car side door lock structures. The inner opening double-pull structure for the car side door lock, when the handle is pulled for the first time, uses the locking transmission arm and the intermediate push arm to move, so that the locking transmission arm is at the unlocking position, and then drives the intermediate push arm to press the locking clutch block so that it cannot pop out. When the inner handle is pulled for the second time, the locking clutch block is pushed to move by the intermediate push arm, and the ratchet push arm and the ratchet release ratchet are cooperated. After the occupant's first misoperation, the car side door will not be opened, which effectively improves the safety factor of the occupant. Compared with the existing inner opening double-pull side door lock, the structure is relatively simple, the cost is reduced, and the product design is simplified.

Description

Technical Field

[0001] The invention relates to the technical field of automobile side door lock structures, in particular to an automobile side door lock inner opening double-pull structure. Background Art

[0002] The central door lock of a car is designed to make the use of the car convenient and safe, and to centrally control the locking and opening of the four doors. The working principle of the central door lock is to convert electrical energy into mechanical energy, and use the motor to drive the gear to rotate to open and close the door. The basic components are mainly composed of door lock switch, door lock actuator, and door lock controller. Door lock switch: Most central door lock switches are composed of a main switch and a sub-switch. The main switch is installed on the door next to the driver. The main switch can lock or open all the doors of the car; the sub-switch is installed on the other doors and can control a door separately. Door lock actuator: The door lock actuator is controlled by the door lock controller to perform the locking and opening tasks of the door lock. There are three main structures: electromagnetic, DC motor and permanent magnet motor.

[0003] Most of the existing car side door locks use the form of a single pull to open the car side door, which can easily cause passengers to operate the inner handle by mistake or get off the car without paying attention to the outside of the car. Pulling the door with the inner handle alone may cause an accident, which is very dangerous. A small number of products that use double pulls to open the car have complex structures, a large number of parts, and high costs. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an inward-opening double-pull structure for a car side door lock, which solves the problem that the existing car side door locks use an inward-opening single-pull form to open the car side door, which is easy to cause occupants to operate incorrectly, and a small number of them use an inward-opening double-pull form, which has a complex structure and high cost.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an inward-opening double-pull structure for a car side door lock, comprising a main body, a motor fixedly connected to the back of the main body, an output end of the motor fixedly connected to a worm through a coupling, a double gear rotatably connected to the right side of the main body, and one side of the outer surface of the double gear meshes with one side of the outer surface of the worm, a locking transmission arm fixedly connected to the right side of the main body, a locking clutch block fixedly connected to the bottom of the locking transmission arm through a locking clutch block spring, a ratchet push rod fixedly connected to the left side of the locking transmission arm, and a An outward-opening rotating shaft, the outer surface of which is fixedly connected with a pawl push arm and an intermediate push arm in sequence from top to bottom, the bottom of the main body is fixedly connected with a base body, the top of the base body is fixedly connected with a connecting bridge, the top of the connecting bridge is fixedly connected with a pawl opening arm through a pawl buffer block, the top of the pawl buffer block is fixedly connected to the inner wall of the main body, the bottom of the base body is rotatably connected with a ratchet shaft, and the outer surface of the ratchet shaft is fixedly connected with a ratchet, the bottom of the base body and the left side of the ratchet shaft is fixedly connected with a pawl, and one side of the pawl is meshed with one side of the outer surface of the ratchet.

[0006] Preferably, the left end of the ratchet push rod is fixedly connected to a push rod compression spring, and the left end of the push rod compression spring is fixedly connected to the inner wall of the main body.

[0007] Preferably, an outward-opening torsion spring is sleeved on the outer surface of the outward-opening rotating shaft, and the bottom end of the outward-opening torsion spring is fixedly connected to the top of the main body.

[0008] Preferably, a base plate is fixedly connected to the bottom of the base body.

[0009] Preferably, an inner opening fixing plate is fixedly connected to the left side of the main body, and an inner opening arm is rotatably connected to the left side of the inner wall of the inner opening fixing plate.
