Examples

As shown in fig. 1 and 2, the present invention specifically relates to a child safety mechanism for an automobile door lock, which includes a housing 100, wherein the housing 100 includes:

a connecting plate 400, wherein the connecting plate 400 is rotatably connected to the housing 100 through a first rotating shaft 410; the connection plate 400 can rotate in the axial direction of the first rotation shaft 410.

One end of the pull rod 500 is movably connected to the connecting plate 400, and the other end of the pull rod 500 abuts against the release lever 200; when the pull rod 500 abuts against the release lever 200, the release lever 200 can be driven to rotate through the pull rod 500 so as to unlock the vehicle door; when the pull rod 500 is separated from the release lever 200, the release lever 200 cannot rotate, so that the locking of the child safety mechanism is completed;

it should be noted that the two states of child safety are: locking and unlocking.

In an unlocked state, the pull rod 500 and the release lever 200 abut against each other, and since the pull rod 500 is movably connected to the connecting plate 400, the pull rod 500 can be driven to move when the connecting plate 400 rotates along the axial direction of the first rotating shaft 410, and since the pull rod 500 and the release lever 200 abut against each other, the pull rod 500 drives the release lever 200 to rotate in the moving process, so that the vehicle door can be opened.

When the lock state, the pull rod 500 is separated from the release rod 200, the release rod 200 loses the rotating power, and the vehicle door can not be opened, thereby ensuring the safety of children in the vehicle.

The release lever further comprises a driving mechanism 300, wherein the driving mechanism 300 can drive the pull rod 500 to rotate relative to the connecting plate 400, so that the pull rod 500 is separated from the release lever 200.

The driving mechanism 300 is configured to drive the pull rod 500 to rotate relative to the connecting plate 400, and the pull rod 500 is separated from the release lever 200 by the driving mechanism 300, thereby achieving the purpose of locking.

The child safety mechanism is simple in structure and convenient to operate, can achieve the purpose of child safety, guarantees the safety of children in the car, and can save certain operation space in the car lock shell 100 under the condition that the guarantee function is not affected, so that the car lock is simplified, convenient and miniaturized.

A stop block 510 is arranged at one end of the pull rod 500 movably connected to the connecting plate 400, the first rotating shaft 410 is connected with a return spring 420, and one end of the return spring 420 abuts against the stop block 510.

The return spring 420 is sleeved on the surface of the first rotating shaft 410, one end of the return spring 420 abuts against the casing 100, and the other end of the return spring 420 abuts against the stopper 510. A gap is formed between the stopper 510 and the connecting plate 400, and when one side of the pull rod 500 is influenced by an external force, so that the pull rod 500 rotates relative to the connecting plate 400, the return spring 420 abutted by the stopper 510 is continuously compressed, so as to complete the locking of the child safety.

When the external force on one side of the pull rod 500 disappears, the pull rod 500 reversely rotates relative to the connection plate 400 by the elasticity of the return spring 420, at this time, the pull rod 500 returns to the original degree by the action of the return spring, and meanwhile, the other end of the pull rod 500 and the release lever 200 abut against each other to complete the unlocking of the child safety.

In addition, the existence of the return spring 420 ensures that the pull rod 500 always abuts against the release lever 200 in the unlocked state of the child safety, and avoids the pull rod 500 from being disengaged from the release lever 200 in the case of other action procedures.

As shown in fig. 2, 4 and 7, one end of the pull rod 500 located at the release lever 200 is a "hook" structure, the release lever 200 is provided with a connection column 210 used in cooperation with the "hook" structure, and the pull rod 500 and the connection column 210 are in two states of abutting and separating.

One end of the pull rod 500 is arranged to be in a hook shape, so that the pull rod 500 is convenient to be mutually abutted with the connecting column 210 on the release lever 200, the connecting column 210 is hooked through the pull rod 500, and the release lever 200 is stably driven to rotate, so that the unlocking purpose is achieved. When the hook-shaped structure of the pull rod 500 is separated from the connecting column 210, the purpose of locking is achieved.

As shown in fig. 2, 3 and 4, the driving mechanism 300 includes a driving assembly connected to the housing 100, a driving wheel 312 and a driving block 313, wherein the driving wheel 312 and the driving block 313 are both rotatably connected to the housing 100; the driving assembly can drive the driving wheel 312 to rotate, and the driving wheel 312 drives the driving block 313 to rotate towards the pull rod 500, so as to separate the pull rod 500 from the release lever 200.

The driving mechanism 300 is a structure capable of driving the pull rod 500 to move, and may be a motor drive, a link drive, a gear drive, or the like, and in this embodiment, it is preferable that the gear drives the driving block 313 to rotate, and the pull rod 500 is separated from the release lever 200 by the driving block 313.

As shown in fig. 3, 4 and 6, the driving wheel 312 has a fan-shaped structure, and a part of the arc-shaped side of the driving wheel 312 is provided with a tooth-shaped structure 3121, and another part of the arc-shaped side of the driving wheel 312 is a normal arc-shaped surface 3122. The driving block 313 is located at one side of the driving wheel 312, the driving block 313 and the pull rod 500 are in a butt joint state and a separation state, when the driving block 313 and the pull rod 500 are in butt joint, the pull rod 500 rotates relative to the connecting plate 400, and at the moment, the pull rod 500 is separated from the release lever 200, so that the purpose of child safety locking is achieved.

When the driving block 313 is separated from the lever 500, the lever 500 is always abutted against the release lever 200 by the return spring 420 connected to the first rotating shaft 410 to complete the child safety unlocking.

The driving assembly comprises a driving motor 310, the driving motor 310 is connected with a transmission worm 311, and the transmission worm 311 is meshed with the driving wheel 312 and can drive the driving wheel 312 to rotate.

Through the meshing of the transmission worm 311 and the tooth structure 3121 of the driving wheel 312, the stability and the accuracy in the power transmission process are ensured.

A guide post 314 is arranged on one side of the driving wheel 312, a transverse groove 315 matched with the guide post 314 is arranged on the driving block 313, and the guide post 314 is connected with the transverse groove 315 in a clamping manner.

It should be noted that the guiding column 314 is connected to the arc surface 3122 of the driving wheel 312, and when the driving motor 310 drives the driving wheel 312 to rotate through the transmission worm 311, the guiding column 314 connected to the arc surface 3122 of the driving wheel 312 rotates synchronously. Since the guide posts 314 are engaged in the lateral grooves 315 of the driving block 313, when the driving wheel 312 rotates, the driving block 313 rotates synchronously and presses the pull rod 500.

A signal switch connected to the housing 100 is disposed on one side of the driving wheel 312, and the rotation stroke of the driving wheel 312 is effectively controlled by the signal switch.

One side of the pull rod 500 is provided with a limiting column (not labeled in the figure) connected to the housing to limit the position of the pull rod 500.
