Fig. 1 to 6 show schematic structural views of the lock device of the present disclosure in different states.

The lock device of the present disclosure is described in detail below with reference to fig. 1 to 6.

It should be noted that the lock device of the present disclosure is a further optimized design of the structure of the lock device of the applicant's previous patent application CN2020112756138, the related technical content of which is incorporated into the present disclosure.

Referring to fig. 1 to 6, the motor unit 202 of the lock device of the present disclosure receives the rotational motion of the output shaft through the gear engaged with the output shaft, and decelerates and commutates the rotational motion of the output shaft.

The output shaft 2021 may be a worm.

The transmission unit 206 has a transmission gear 2061 and a screw 2062, the worm of the motor unit 202 is meshed with the transmission gear 2061 of the transmission unit 206 to transmit the rotational motion of the motor unit 202 to the transmission unit 206, and the screw 2062 is meshed with the nut block 207 to convert the rotational motion of the transmission unit 206 into the reciprocating motion of the nut block 207.

The rotation of the nut block 207 may be restricted by a structure of a housing or the like of the lock device such that the nut block 207 does not rotate.

The nut block 207 is provided with an internal screw hole, and the nut block 207 can be fitted around the screw 2062 through the internal screw hole, and the internal screw of the internal screw hole of the nut block 207 is engaged with the external screw of the screw 2062 to convert the rotation motion of the screw 2062 into the linear motion of the nut block 207.

In some embodiments of the present disclosure, the screw 2062 of the drive 206 is integrally formed with or fixedly connected to the drive gear 2061 and falls within the scope of the present disclosure.

In some embodiments of the present disclosure, as shown in fig. 1, the nut block 207 has a nut block boss portion 2071, the position of the nut block 207 being indicated by the cooperation of the nut block boss portion 2071 with the first switch 2051 and the second switch 2052.

In some embodiments of the present disclosure, referring to fig. 1, one axial end of the transmission 206 is provided with a bearing 2063 to increase the load carrying capacity of the transmission 206.

Referring to fig. 1, in some embodiments of the present disclosure, the lock body mechanism includes a pawl 102, a locking tongue 103, and a self priming mechanism 105.

The structure of the lock body mechanism of the present disclosure may adopt the structure of the lock body mechanism in the applicant's prior chinese patent CN112227851a, and the present disclosure will not be repeated.

As shown in fig. 1-4, a schematic view of the self-priming process (i.e., the locking process) of the lock device of the present disclosure is shown.

Fig. 1 shows the lock device in a fully open position. The deadbolt switch 203 is not triggered, the pawl switch 204 is triggered, and the first switch 2051 is triggered, which indicates that the lock device is in the fully open position via the status signals of the three switches.

When the deadbolt 103 is pushed to the deadbolt switch 203 to be triggered, the motor unit 202 may output a rotational motion such as a forward rotation based on a trigger signal of the deadbolt switch 203, so that the transmission part 206 is rotated forward, and the nut block 207 is driven to move rightward by the rotation of the transmission part 206, as shown in fig. 2, so that the first switch 2051 is released, and at the same time, the nut block 207 pushes the self-priming execution lever 1052 of the self-priming mechanism 105, so that the first end portion of the self-priming driving lever 1051 of the self-priming mechanism 105 engages with the engaging portion 1031 on the deadbolt 103, as shown in fig. 2.

As the nut block 207 continues to move to the right, the self-priming drive rod 1051 of the self-priming mechanism 105 will gradually push the locking bolt 103 to the fully locked position, as shown in fig. 3, at which time the pawl 102 will lock into the locking bolt 103 to hold the locking bolt 103 in the fully locked position while releasing the pawl switch 204, while the second switch 2052 is triggered by the nut block 207.

The second switch 2052 is configured, so that the movement position of the nut block 207 can be more accurately indicated, the full lock position of the lock tongue 103 can be more accurately indicated, and the reverse energizing signal of the motor unit 202 is generated based on the trigger signal of the second switch 2052.

The motor unit 202 is reversely energized based on the trigger signal of the second switch 2052, outputs a reverse rotation motion, drives the nut block 207 to move leftward through the transmission part 206 as shown in fig. 4 until the first switch 2051 is triggered again, and simultaneously the nut block 207 releases the self-priming mechanism 105, and the self-priming mechanism 105 returns to the initial position under the action of the return spring as shown in fig. 4, until the whole sucking process is completed.

Fig. 5 and 6 illustrate an unlocking process of the lock device of the present disclosure.

As shown in fig. 5, when the vehicle control system receives the unlock signal, the motor unit 202 is energized (e.g., the motor is reversed), and the nut block 207 is driven to move leftward by the transmission part 206, so that the first switch 2051 is released, and at the same time, the nut block 207 pushes the unlock lever 104 to rotate.

The unlocking lever 104 pushes the pawl 102 to the unlocking position and triggers the pawl switch 204, as shown in fig. 5, at this time, the latch 103 will rotate to the fully opened position (counterclockwise direction in fig. 5 may be implemented based on the return spring with the pre-tightening force, which is not described again), after the latch 103 triggers the latch switch 203, the motor unit 202 will be reversely energized (e.g. the motor rotates forward), and drives the nut block 207 to move rightward through the transmission part 206 until the first switch 2051 is triggered, as shown in fig. 6, thereby completing the whole unlocking process.

Fig. 7 is a schematic partial structure of a lock device according to an embodiment of the present disclosure, in which three nut block trigger switches may be configured, namely, a first switch 2051, a second switch 2052, and a third switch 2053, the second switch 2052 being used to indicate that the nut block 207 has driven the lock tongue 103 to the full lock position when triggered, and the third switch 2053 being used to indicate that the nut block 207 has driven the pawl 102 to the unlock position when triggered, releasing the lock of the lock tongue 103, the lock tongue 103 will be rotated counterclockwise to the full open position by a pretension spring (not shown).

With the structure shown in fig. 7, the deadbolt switch 203 and the pawl switch 204 shown in fig. 1 to 6 can be eliminated, simplifying the structure of the lock device of the present disclosure.
