For pressing the follower arm 34, when the follower arm 34 rotates, the slave arm 34 pushes the rocker arm follower section 362 to rotate the puller rocker arm 36, and one end of the rocker arm drive section 361 and the lock body 1 can be Pivotly connected, the other end of the rocker arm driven section 362 is connected to the other end of the rocker arm driving section 361, and the rocker arm driving section 361 and the rocker arm driven section 362 are formed in a bent shape, when the unlocking mechanism is activated, The follower arm 34 reset member can drive the slave arm 34 to move to the slave arm flange 341 to be disengaged from the rocker arm follower section 362, and rotate into the bend angle between the rocker arm drive section 361 and the rocker arm follower section 362, To achieve power shutoff, the side of the rocker arm drive section 361 that faces away from the rocker arm driven section 362 is used to press against the bolt 2 such that the rotating suction rocker arm 36 urges the bolt 2 to rotate in the rocker arm drive section 361.

The design of the rocker arm drive section 361 and the rocker arm follower section 362 allows the pick-up rocker arm 36 to receive power from the slave arm 34 and transmit it to the bolt 2, ultimately locking the door lock 100 and bending. The suction rocker arm 36 makes the structure compact here, saves the arrangement space, and can make the transmission efficiency of the mechanism there high.

In some embodiments, the door lock 100 may further include a pull-up rocker returning member 37. The rocker arm resetting section 363 is connected to one end of the rocker arm driving section 361, and the two ends of the suction rocker arm restoring member 37 are respectively elastically connected to the rocker arm.

The rocker arm driving section 361 of the suction rocker arm 36 pushes the bolt pin 24 to rotate the bolt 2, and since the process of sucking the rocker arm 36 to push the bolt 2 is not linear, when the suction rocker arm 36 pushes the bolt 2 During the rotation, the rocker arm driving section 361 rotates relative to the bolt pin 24. The bolt pin 24 is disposed to make the relative rotation of the suction rocker arm 36 and the bolt 2 less during the pushing process, thereby ensuring the position. Transmission efficiency.

The pickup drive mechanism can receive the signal of the detection unit to control its own start and stop. The following describes several embodiments of the door lock 100, which are respectively provided with various detection units.

As shown in FIG. 12 to FIG. 15 , the door lock 100 according to the embodiment of the present application includes: a lock body 1 , a lock tongue 2 , a suction drive mechanism, a first signal switch 41 , and a second signal switch 42 .

The lock tongue 2 is pivotally mounted to the lock body 1, and the pull-in drive mechanism, the first signal switch 41, and the second signal switch 42 are all mounted on the lock body 1, the first signal switch 41, the second signal switch 42 and The pull-in drive mechanism is electrically connected, and when the lock tongue 2 is rotated to the first position, the first signal switch 41 is triggered to cause the pull-in drive mechanism to drive the lock tongue 2 to rotate to the second position, when the lock tongue 2 is rotated to the second position The second signal switch 42 is triggered to close the pull-in drive mechanism.

The locking tongue 2 can be located in a first position and a second position, the door lock 100 is half locked when the locking tongue 2 is in the first position, and the door lock 100 is fully locked when the locking tongue 2 is in the second position, when the passenger of the vehicle 1000 is pushed up After the door, the locking tongue 2 can be in the first position, that is, the locking tongue 2 is half-locked. At this time, the suction driving mechanism works to rotate the locking tongue 2 to the second position, so that the door is fully locked, so that the door can be made The lock 100 is more secure.

Thus, when the passenger closes the door and the lock tongue 2 is in the first position, the lock tongue 2 can trigger the first signal switch 41, the pull-in drive mechanism receives the signal of the first signal switch 41, and the pull-in drive mechanism drives the lock tongue. 2 rotating to the second position, when the locking tongue 2 is rotated to the second position, the locking tongue 2 can trigger the second signal switch 42, and the pickup driving mechanism receives the signal of the second signal switch 42 to close the suction driving mechanism. Thereby, the locking operation of the door lock 100 is completed. After the suction driving mechanism is closed, the driving arm 31 of the suction driving mechanism is driven and reset by the driving arm returning member 33, and the suction rocker arm 36 of the suction driving mechanism is sucked and shaken. The arm reset member 37 is driven to be reset, thereby resetting the entire pull-in drive mechanism.

According to the door lock 100 of the embodiment of the present application, by providing the lock body 1, the lock tongue 2, the suction drive mechanism, the first signal switch 41 and the second signal switch 42, the door lock 100 can be automatically half-haled after the passenger closes the door. The lock state to the full lock state is convenient for operation, and can prevent the door lock 100 from being unlocked due to passenger forgetting, and the automatic opening of the vehicle 1000 during driving increases the safety performance of the door lock 100, using two The signal switch can realize the start and stop of the suction drive mechanism, the parts are small, the installation space is small, the door lock 100 is sensitive from half lock to full lock, and the reliability is high, so that the suction drive mechanism can accurately pick up and reset. , high security.

In some embodiments, as shown in FIGS. 12-15, the locking tongue 2 is provided with a first boss 25 and a second boss 26, and when the tongue 2 is rotated to the first position, the first boss 25 triggers the first a signal switch 41, when the lock tongue 2 is rotated to the second position, the second boss 26 triggers the second signal switch 42 to trigger the first signal switch 41 and the second through the first boss 25 and the second boss 26, respectively The signal switch 42 has a simple structure and is convenient to manufacture, so that the manufacturing cost of the door lock 100 can be reduced.

In some embodiments, as shown in FIGS. 14 and 15, when the tongue 2 is rotated to the first position, the first working surface 251 of the first boss 25 presses against the contact of the first signal switch 41, at the lock When the tongue 2 is rotated to the second position, the first working surface 251 of the first boss 25 releases the contact of the first signal switch 41 and the second working surface 261 of the second boss 26 presses the second signal switch 42 The contact, the first working surface 251 is pressed against the contact of the first signal switch 41, and the second working surface 261 is pressed against the contact of the second signal switch 42 to convert the locked state of the locking tongue 2 into the first signal. The electrical signals of the switch 41 and the second signal switch 42 are simple and compact, and the signal feedback is accurate and rapid, so that the working state of the pull-in driving mechanism can be controlled in time and accurately.

In some embodiments, as shown in Figures 12-15, the first working surface 251 of the first boss 25 and the second working surface 261 of the second boss 26 are radially spaced relative to the axis of rotation of the bolt 2. The contacts of the first signal switch 41 and the contacts of the second signal switch 42 are radially spaced along the axis of rotation of the bolt 2, and the first working surface 251 is when the passenger pushes the door to position the bolt 2 in the first position. Stopping the first signal switch 41, the suction drive mechanism operates and the lock tongue 2 rotates, and the first boss 25 and the second boss 26 also rotate with the lock tongue 2 until the lock tongue 2 rotates through a certain angle. When the second working surface 261 stops against the second signal switch 42, the suction drive mechanism stops working.

Thus, during the rotation of the tongue 2, the first boss 25 and the second boss 26 can sequentially trigger the first signal switch 41 and the second signal switch 42, thereby causing the first signal switch 41 and the second signal The switch 42 can continuously control the suction driving mechanism to complete the process of locking the tongue 2 from half lock to full lock, and the control method only needs to be set according to the positions of the first boss 25 and the second boss 26 . The positions of the first signal switch 41 and the second signal switch 42 can realize the control of the pull-in driving mechanism, the design cycle is short, and is easy to implement, thereby reducing the design cost of the door lock 100, and the radially spaced apart In the arrangement, the cooperation of the first boss 25 with the first signal switch 41 and the cooperation of the second boss 26 and the second signal switch 42 do not interfere with each other.

As shown in FIGS. 1-4, the distance from the first working surface 251 of the first boss 25 to the axis of rotation of the bolt 2 is smaller than the distance from the second working surface 261 of the second boss 26 to the axis of rotation of the bolt 2. The distance of the contact of the first signal switch 41 to the axis of rotation of the bolt 2 is less than the distance of the contact of the second signal switch 42 to the axis of rotation of the bolt 2.

Since the first working surface 251 triggers the first signal switch 41 during the rotation of the locking tongue 2 from the first position to the second position, the first boss 25 and the second boss 26 need to rotate with the bolt 2 The angle until the second working surface 261 stops against the contact of the second signal switch 42 because the distance of the contact of the first signal switch 41 to the axis of rotation of the bolt 2 is smaller than the contact of the second signal switch 42 to the bolt The distance between the rotation axis of the second signal switch 41 and the second signal switch 42 can be corresponding to the corresponding signal switch, so that the structure of the door lock 100 can be more compact, and the arrangement space of the door lock 100 can be saved. After the first signal switch 41 is triggered by the lock tongue 2 in the first position, the first signal switch 41 can stop the working surface of the first boss 25 until the second signal switch 42 stops working against the second boss 26. The first boss 25 is disposed on the radially inner side of the rotating shaft of the bolt 2 with respect to the second boss 26, and the space of the first boss 25 can be set to a sufficient space to ensure the first signal switch 41. After being triggered by the first boss 25, the driving unit can be based on the first The signal of the signal switch 41 drives the bolt 2 to rotate a sufficient angle to cause the bolt 2 to rotate to the second position.

In some embodiments, as shown in Figures 12-15, the first working surface 251 of the first boss 25 and the second working surface 261 of the second boss 26 are axially spaced relative to the axis of rotation of the bolt 2. The contacts of the first signal switch 41 and the contacts of the second signal switch 42 are axially spaced along the axis of rotation of the bolt 2, so that the first signal switch 41 and the second signal switch 42 are prevented from being assembled. A signal switch 41 and the second signal switch 42 are too close together, resulting in assembly difficulties.

For example, as shown in FIGS. 12-15, the first working surface 251 of the first boss 25 protrudes from the surface of the bolt 2 and the height of the surface is larger than the second working surface 261 of the second boss 26. The height value of the surface of the second signal switch 41, the distance from the contact of the first signal switch 41 to the surface of the bolt 2 is greater than the distance of the contact of the second signal switch 42 to the surface of the bolt 2, the first boss 25 and the second protrusion This arrangement of the table 26 also prevents the first working surface 251 of the first boss 25 from accidentally touching the contact of the second signal switch 42 or the second working surface of the second boss 26 when the tongue 2 is rotated. 261 mistakenly touches the contact of the first signal switch 41.

In some embodiments, as shown in Figures 12-15, the contacts of the first signal switch 41 and the contacts of the second signal switch 42 are circumferentially spaced apart along the axis of rotation of the bolt 2, due to the locking tongue 2 Is rotated to lock the door, so the first boss 25 and the second boss 26 also rotate with the bolt 2, the contact of the first signal switch 41 and the contact of the second signal switch 42 along the bolt 2 The circumferential axes of the axes of rotation are spaced apart such that the contacts of the first signal switch 41 cooperate with the first working surface 251 and the contacts of the second signal switch 42 cooperate with the second working surface 261.

In some embodiments, as shown in FIGS. 12-15, the first boss 25 has a first guiding surface 252 and a first working surface 251, and one end of the first guiding surface 252 is connected to the first working surface 251, first The distance from the other end to the end of the guide surface 252 from the axis of rotation of the bolt 2 gradually increases.

The second boss 26 has a second guiding surface 262 and a second working surface 261. One end of the second guiding surface 262 is connected to the second working surface 261, and the second guiding surface 262 is from the other end to the rotation axis of the locking tongue 2 from the other end. The distance gradually becomes larger.

Thus, the first guiding surface 252 can guide the contact of the first signal switch 41, and the second guiding surface 262 can guide the contact of the second signal switch 42 so that the first signal can be made The contact of the switch 41 and the contact of the second signal switch 42 can smoothly cooperate with the first working surface 251 or the second working surface 261, so that the rotation of the locking tongue 2 is smooth, and the contact between the contact and the working surface is not rigid. Causes the lock tongue 2 to rotate.

In some examples, as shown in FIGS. 12-15, the first guiding surface 252 of the first boss 25 may be a slope that gradually slopes outward in the radial direction of the first signal switch 41, first The guide surface 252 is inclined from an end facing away from the first working surface 251 to an end connected to the first working surface 251 in a direction away from the rotational axis of the locking tongue 2, such that during the relative rotation of the first signal switch 41 and the locking tongue 2 The first boss 25 can gradually approach the first signal switch 41 until the contact of the first signal switch 41 contacts the first working surface 251 of the first boss 25, so that the rotation of the bolt 2 can be smooth, and will not The occurrence of a jam, or the contact of the first signal switch 41 rigidly contacts the first boss 25, of course, the first guiding surface 252 may also be a curved surface.

In some examples, as shown in FIGS. 12-15, the second guiding surface 262 of the second boss 26 may be a curved surface, so that during the relative rotation of the second signal switch 42 and the locking tongue 2, it can be ensured. The distance between the contact of the second signal switch 42 and the second boss 26 is constant, thereby preventing the second boss 26 from accidentally touching the contact of the second signal switch 42, and the resulting pull-in drive mechanism is rotated to the lock tongue 2 to The second position is closed before the door lock 100 is prevented from being locked in place. Of course, the second guiding surface 262 can also be a slope.

As shown in FIG. 12 to FIG. 15, the door lock 100 according to other embodiments of the present application includes: a lock body 1, a lock arm 6, a shift fork 7, a lock tongue 2, a suction drive mechanism, a first signal switch 41, and The second signal switch 42.
