Fig. 1 is a schematic structural view of a lock device for a sliding door according to one embodiment of the present disclosure. Fig. 2 is a schematic view of a locked state of a lock device for a sliding door according to one embodiment of the present disclosure.

As shown in fig. 1, the lock device for a sliding door of the present disclosure may include a latch bolt part 100, a pawl part 200, a driving device 300, a driving gear part 400, and a pawl driving lever 500, etc.

The latch bolt assembly 100 has a first axis of rotation and has a first locking position, which may be a full locking position, and a second locking position, which may be a half locking position. Additionally, the tongue component 100 may also include an unlocked position in which the tongue component 100 is able to release a shackle and effect unlocking of the lock device for a sliding door of the present disclosure.

That is, when the latch bolt assembly 100 is driven and rotated, the latch bolt assembly 100 is capable of moving to one of a first latched position, a second latched position, and an unlatched position. For example, in the orientation shown in fig. 2, when latch bolt assembly 100 is rotated counterclockwise, it is able to move from the first latched position to the second latched position, and when latch bolt assembly 100 is rotated further counterclockwise, it is able to move from the second latched position to the unlocked position, effecting unlocking of the latch mechanism for the sliding door. In contrast, when latch bolt assembly 100 is rotated clockwise, it is movable from the unlocked position to the second locked position, and when latch bolt assembly 100 is further rotated counterclockwise, it is movable from the second locked position to the first locked position, thereby effecting locking of the lock device for a sliding door of the present disclosure.

In a specific embodiment, counterclockwise rotation of latch bolt assembly 100 may be accomplished by a return force provided by a return spring or the like, and clockwise rotation of latch bolt assembly 100 may be accomplished by driving gear assembly 400, as will be described in greater detail below.

In this disclosure, pawl member 200 has a second axis of rotation and retains latch member 100 in the first latched position when pawl member 200 is in the first position and retains latch member 100 in the second latched position when pawl member 200 is in the second position. In one embodiment, the first position and the second position may be the same position or different positions.

Specifically, when the first position and the second position are the same, if pawl assembly 200 is held in a certain position at the time of unlocking, latch bolt assembly 100 will be able to rotate from the first latched position to the unlatched position and will not be latched in the second latched position. On the other hand, when the first position and the second position are different positions, the tongue part 100 can be locked in the second locking position at the time of unlocking, and further driving of the pawl part 200 is required to rotate the tongue part 100 from the second locking position to the unlocking position.

In contrast, during locking, latch member 100 may be driven to rotate by driving gear member 400 into engagement with latch first feature 101 of latch member 100, wherein pawl first feature 201 of pawl member 200 engages the outer surface of latch member 100 and slides into the second latched position as latch member 100 rotates from the unlocked position to the second latched position, wherein pawl member 200 is in the second position and is correspondingly capable of retaining latch member 100 in the second latched position, and further wherein pawl first feature 201 of pawl member 200 is continuously engaged with the outer surface of latch member 100 as drive gear member 400 is continuously rotated and pushes latch member 100 from the second latched position to the first latched position and slides into the first latched position, wherein pawl member 200 is in the first position. More preferably, the first latch feature 101 is formed as an arm of the latch bolt assembly 100 and the first pawl feature 201 is formed as an arm of the pawl assembly 200.

Fig. 3 is a schematic structural view of a driving device according to an embodiment of the present disclosure.

As shown in fig. 3, the driving apparatus 300 of the present disclosure may include a motor and a decelerator connected to the motor, which may be a worm gear decelerator, and an output shaft of the worm gear decelerator may be provided with a pinion gear capable of meshing with teeth of the driving gear part 400, thereby enabling the driving gear part 400 to have a large output torque.

In the present disclosure, the driving gear part 400 may be an incomplete gear, for example, it may be a sector gear. The driving gear member 400 has a third rotation axis when driven by the driving device 300, and the driving gear member 400 can be rotated in a first direction or in a second direction when the motor is rotated in forward and reverse directions, wherein the first and second directions are opposite directions. Also, when the driving gear part 400 rotates in a first direction, it can drive the latch bolt part 100 to rotate and cause the locking device for the sliding door to be locked, and when the driving gear part 400 rotates in a second direction, it can simultaneously drive the pawl driving lever 500 and the power take-off lever 600 to cause the locking device for the sliding door to be powered outward while unlocking. More specifically, in the direction shown in fig. 1, the first direction is a counterclockwise direction and the second direction is a clockwise direction.

More specifically, as shown in fig. 1, the pawl driving lever 500 has a fourth axis of rotation and the pawl driving lever 500 is capable of being driven and rotated by the drive gear member 400 and driving the pawl member 200 in rotation by rotation of the pawl driving lever 500 to retain the tongue member 100 in either the first or second latched position.

Specifically, the fourth rotation axis of the pawl driving lever 500 is located at a center position of the pawl driving lever 500 and an upper end of the pawl driving lever 500 is capable of receiving power and a lower end of the pawl driving lever 500 cooperates with the pawl member 200 to rotate the pawl member 200. In one embodiment, the pawl member 200 includes a pawl second feature 202 that is capable of engaging a lower end (drive rod third feature 503) of the pawl drive rod 500 to enable the pawl drive rod 500 to drive rotation of the pawl member 200.

In this disclosure, the pawl driving lever 500 is also capable of driving the pawl member 200 to a third position in which the pawl member 200 can release the tongue member 100. Accordingly, the pawl driving lever 500 is capable of rotating from a third position to either the first position or the second position under the force of a return force provided by a return spring or the like. That is, in the process of locking the lock device for a sliding door of the present disclosure, the pawl member 200 can be rotated by the restoring force provided by the restoring spring so as to limit the position of the latch bolt member 100.

As shown in fig. 1, the lock device for a sliding door of the present disclosure further includes a power output lever 600, the power output lever 600 having a fifth rotation axis, and the power output lever 600 being capable of being driven by the driving gear part 400 so as to output power outwardly through the power output lever 600.

Fig. 4 is a schematic diagram of a power take-off process of a lock device for a sliding door according to one embodiment of the present disclosure.

As shown in fig. 1 and 4, the power take-off lever 600 of the present disclosure includes a plurality of interface portions 601 for connecting plugs of the output wires 602 to thereby provide power to the outside through the output wires 602. More preferably, the interface 601 has different distances from the fifth rotation axis, so that the output pull wire 602 connected to the power output rod 600 has different movement strokes, accordingly, the output pull wire 602 with a longer movement stroke can be connected to the front lock, the output pull wire 602 with a shorter movement stroke can be connected to the full-open lock, and the like, thereby greatly reducing the complexity of the transfer mechanism, even eliminating the transfer structure, and improving the transmission efficiency of the lock system of the whole sliding door. In a specific embodiment, the output cord 602 may be a bowden cord.

In one embodiment, the lock device for a sliding door may further include an intermediate lever member 700, the intermediate lever member 700 being capable of being driven and rotated by the driving gear member 400, and the power output lever 600 being driven to rotate by the rotation of the intermediate lever member 700. In addition, the intermediate lever member 700 of the present disclosure is also used to drive the pawl driving lever 500 to rotate, that is, by the arrangement of the intermediate lever member 700, when the driving gear member 400 drives the intermediate lever member 700 to rotate, the intermediate lever member 700 can synchronously drive the power output lever 600 and the pawl driving lever 500 to rotate, thereby effecting unlocking of the respective locks of the lock system of the sliding door.

Thus, by providing the intermediate lever member 700, the external power output and the internal unlocking of the lock device for a sliding door of the present disclosure can be separated. The intermediate lever member 700 can directly drive the pawl driving lever 500 to effect unlocking, thereby reducing the transmission path to the lock device for a sliding door (rear lock), improving efficiency, so that the lock device for a sliding door can overcome a greater sealing force. Meanwhile, the middle lever part 700 can drive the power output lever 600 to output two paths of power, other moving parts can be actuated, for example, the front lock and the full unlock of the lock system of the sliding door are actuated, so that the complexity of a transfer mechanism can be reduced, the stability can be improved, even the transfer structure can be omitted, and the transmission efficiency of the lock system of the whole sliding door can be improved.

In a preferred embodiment, the intermediate lever member 700 has the same axis of rotation as the power take-off lever 600. More specifically, the intermediate lever member 700 and the power take-off lever 600 can be provided on the same hinge shaft, and both can be rotated with respect to the hinge shaft.

Fig. 5 is a schematic structural view of an intermediate lever member according to one embodiment of the present disclosure.

As shown in fig. 5, the intermediate lever member 700 includes an intermediate lever first feature 701, the intermediate lever first feature 701 being configured to mate with the drive gear member 400 such that the intermediate lever member 700 is driven in rotation by the drive gear member 400. Specifically, the intermediate lever first feature 701 is formed as a cylindrical protrusion, and one side surface of the driving gear member 400 can contact the outer peripheral surface of the cylindrical protrusion, thereby pushing the intermediate lever member 700 to rotate about the fifth rotation axis. Also, the axes of the cylindrical protrusions are disposed in parallel with the fifth rotation axis and have a first preset distance, so that when the driving gear part 400 applies a force to the middle lever part 700, the force has a moment arm of a preset length (same as the preset distance).

Moreover, the intermediate lever member 700 also includes an intermediate lever second feature 702, the intermediate lever second feature 702 being configured to mate with an end of the pawl driving lever 500 (the driving lever second feature 502) such that the intermediate lever member 700 is capable of driving the pawl driving lever 500 in rotation when the intermediate lever member 700 is driven in rotation by the drive gear member 400. Moreover, the intermediate lever second feature 702 is formed as one arm of the intermediate lever member 700, e.g., the contact area of the intermediate lever second feature 702 with the pawl driving lever 500 and the fifth rotational axis have a second predetermined distance therebetween, preferably the first predetermined distance is greater than the second predetermined distance.

The intermediate lever member 700 further includes an intermediate lever third feature 703, the intermediate lever third feature 703 being configured to cooperate with a side surface of the power take-off lever 600 such that the intermediate lever member 700 is capable of driving the power take-off lever 600 in rotation when the intermediate lever member 700 is driven in rotation by the drive gear member 400. Furthermore, the intermediate lever third feature 703 is formed as a stop protruding from the rotational plane of the intermediate lever member 700. More preferably, a third preset distance is provided between the position where the limiting portion contacts the power output lever 600 and the fifth rotation axis, wherein the first preset distance is greater than the third preset distance.

That is, as shown in fig. 1, when the driving gear part 400 drives the middle lever part 700, the middle lever part 700 is rotated counterclockwise, and accordingly, the power output lever 600 is rotated counterclockwise in synchronization, and at this time, the pawl driving lever 500 is rotated clockwise, and the pawl part 200 is driven to rotate counterclockwise, so that unlocking is achieved.

In addition, the pawl driving lever 500 can be reset by a reset force provided by a reset spring, i.e., a counterclockwise motion, thereby pushing the intermediate lever member 700 in a reverse direction and rotating and resetting the intermediate lever member 700 clockwise. The intermediate lever 700 can be reset by a reset force provided by a reset spring or the like.

In the present disclosure, the lock device for a sliding door may further be provided with a limiting member capable of limiting the middle lever member 700 to the initial position shown in fig. 1. To prevent the intermediate lever member 700 from passing over this position during reset, causing damage to the lock device for the sliding door.

Fig. 6 is a schematic structural view of a lock device for a sliding door according to another embodiment of the present disclosure.

As shown in fig. 6, the lock device for a sliding door of the present disclosure may further include a mechanical unlocking lever member 800, one end of the mechanical unlocking lever member 800 is connected with an input wire 801, and rotation of the mechanical unlocking lever member 800 is achieved by a driving force input by the input wire 801, thereby achieving mechanical unlocking of the lock device for a sliding door, wherein the mechanical unlocking lever member 800 has a sixth rotation axis, and particularly, a connection of the input wire 801 and the mechanical unlocking lever member 800 is spaced from the sixth rotation axis of the mechanical unlocking lever member 800, thereby enabling a force applied to the mechanical unlocking lever member 800 by the input wire 801 to have a proper moment arm.

The sixth axis of rotation coincides with the fourth axis of rotation, that is, the mechanical unlocking lever member 800 has the same axis of rotation as the pawl driving lever 500, thereby facilitating the arrangement of the parts of the lock device for a sliding door of the present disclosure and reducing the volume of the lock device for a sliding door.

Specifically, when the mechanical unlocking lever member 800 is rotated, it can directly or indirectly drive the pawl member 200 to rotate, thereby achieving mechanical unlocking of the lock device for a sliding door of the present disclosure. In the structure shown in fig. 6, the mechanical unlocking lever member 800 is capable of selectively driving the pawl driving lever 500 to rotate and indirectly driving the pawl driving lever 200 to rotate through the pawl driving lever 500.

In one embodiment of the present disclosure, the lock device for a sliding door of the present disclosure further comprises a child-guard bar member 900, the child-guard bar member 900 being capable of being driven to be in a first state or a second state, wherein the mechanical unlocking bar member 800 is capable of driving the pawl driving bar 500 to rotate, i.e. allowing the mechanical unlocking bar member 800 to drive the pawl driving bar 500, when the child-guard bar member 900 is in the first state, and wherein the mechanical unlocking bar member 800 is incapable of driving the pawl driving bar 500 to rotate, i.e. not allowing the mechanical unlocking bar member 800 to drive the pawl driving bar 500, when the child-guard bar member 900 is in the second state.

That is, the lock device for a sliding door of the present disclosure has a child-proof function, and can unlock the lock device for a sliding door of the present disclosure by the mechanical unlocking lever member 800 only when the child-proof function is in a disabled state, i.e., the child-proof lever member 900 is in a first state, and on the other hand, when the child-proof function is in an activated state, i.e., the child-proof lever member 900 is in a second state, the unlocking of the vehicle door by driving the mechanical unlocking lever member 800 is not allowed to be performed, so that the vehicle door is prevented from being unlocked by a child, and the safety performance of the lock device for a sliding door is improved.

FIG. 7 is a schematic structural view of a pawl driving lever according to one embodiment of the present disclosure. Fig. 8 is a schematic structural view of a mechanical unlocking lever member according to one embodiment of the present disclosure.

In the present disclosure, as shown in fig. 7 and 8, the mechanical unlocking lever member 800 includes a mechanical unlocking lever first feature 802, the pawl driving lever 500 includes a driving lever first feature 501, and the mechanical unlocking lever first feature 802 is different from a movement plane of the driving lever first feature 501, in other words, a movement envelope of the driving lever first feature 501 and a movement envelope of the mechanical unlocking lever first feature 802 of the present disclosure do not overlap.

Moreover, the child-resistant lever member 900 being in the first state includes at least a portion of the child-resistant lever member 900 engaging the mechanical release lever first feature 802 and at least a portion of the child-resistant lever member 900 engaging the drive lever first feature 501, whereby a driving force can be transferred between the mechanical release lever member 800 and the pawl drive lever 500 through the child-resistant lever member 900.

Fig. 9 and 10 are schematic structural views of a child-resistant lever component according to one embodiment of the present disclosure.

Specifically, as shown in fig. 6, 9 and 10, one end of the child-resistant lever member 900 is rotatably disposed on the mechanical unlocking lever first feature 802 such that the child-resistant lever member 900 has a seventh axis of rotation, which in the present disclosure is not a fixed axis, that can vary with positional variation of the mechanical unlocking lever first feature 802. The other end of the child-resistant lever member 900 is provided with a child-resistant lever first feature 901, the child-resistant lever first feature 901 being capable of mating with the mechanical unlocking lever first feature 802 and the driving lever first feature 501.

On the other hand, the child-resistant lever member 900 being in the second state includes the child-resistant lever first feature 901 being remote from the mechanical unlocking lever first feature 802 and the drive lever first feature 501, whereby no transmission connection is established between the mechanical unlocking lever member 800 and the pawl driving lever 500, and at this time the mechanical unlocking lever member 800 does not drive the pawl driving lever 500 to rotate even if the mechanical unlocking lever member 800 is pulled to rotate by the input wire 801, and accordingly the lock device for a sliding door is not unlocked.

The mechanical unlocking lever first feature 802 includes a force applying surface, and the drive lever first feature 501 includes a force receiving surface that is capable of applying a force to the child-resistant lever first feature 901 and transmitting the force through the child-resistant lever first feature 901 to the force receiving surface of the drive lever first feature 501, thereby effecting a force transfer between the mechanical unlocking lever member 800 and the pawl drive lever 500. More preferably, the child-resistant lever first feature 901 includes a surface that mates with the force-applying surface and includes a surface that mates with the force-receiving surface, and the force-applying surface is formed as an outwardly convex curved surface that is formed as an inwardly concave surface so as not to easily slip from this position when the child-resistant lever first feature 901 is positioned between the mechanical unlocking lever first feature 802 and the driving lever first feature 501.

Fig. 11 and 12 are schematic structural views of a child-resistant unlocking lever member according to one embodiment of the present disclosure.

As shown in fig. 9-12, the child resistant lever member 900 of the present disclosure includes a child resistant lever second feature 902, wherein the child resistant lever second feature 902 is operable by the child resistant release lever member 910 to place the child resistant lever member 900 in either the first state or the second state.

In one embodiment, the child-resistant release lever member 910 is operable such that it is rotatable about one end of the child-resistant release lever member 910, for example, the child-resistant release lever member 910 has an eighth axis of rotation disposed parallel to and non-coincident with the seventh axis of rotation. That is, even if the position of the seventh axis of rotation varies with the variation of the mechanical unlocking lever first feature 802, the eighth axis of rotation does not coincide with the respective positions of the seventh axis of rotation.

Fig. 13 is a schematic structural view of a child-resistant lever component in a first state according to one embodiment of the present disclosure. Fig. 14 is a schematic structural view of a child-resistant lever component in a second state in accordance with one embodiment of the present disclosure.

The child-resistant unlocking lever member 910 includes a guide groove 911, along which guide groove 911 the child-resistant lever second feature 902 is arranged to slide, whereby when the child-resistant unlocking lever member 910 is rotated in a first rotational direction (clockwise as shown in fig. 13 or 14), the child-resistant lever second feature 902 is slidably guided by the guide groove 911 and causes rotation of the child-resistant lever member 900 (clockwise as shown in fig. 13 or 14) such that the child-resistant lever first feature 901 moves from a position away from the mechanical unlocking lever member 800 and the pawl driving lever 500 to a position between the mechanical unlocking lever member 800 and the pawl driving lever 500, at which point the child-resistant function is disabled, which may be unlocked by the mechanical unlocking lever member 800. Still further, at this point if the mechanical unlocking lever member 800 is operated, the child-resistant lever first feature 901 will continue to slide within the guide groove 911, with the segment of the guide groove being arranged as a circular arc centered about the sixth axis of rotation, thereby ensuring that the child-resistant lever first feature 901 will not disengage from between the mechanical unlocking lever first feature 802 and the drive lever first feature 501.

In the opposite operation, when the child-resistant release lever member 910 is rotated in the second rotational direction (counterclockwise as shown in fig. 13 or 14), the child-resistant lever second feature 902 is slidably guided by the guide groove 911 and causes rotation of the child-resistant lever member 900 (counterclockwise as shown in fig. 13 or 14) such that the child-resistant lever first feature 901 moves from a position between the mechanical release lever member 800 and the pawl driving lever 500 to a position away from the mechanical release lever member 800 and the pawl driving lever 500, at which time the child-resistant function is activated, at which time the pawl driving lever 500 is not driven to rotate even if the mechanical release lever member 800 is rotated, thereby preventing unlocking by the mechanical release lever member 800.

Fig. 15 is a schematic structural view of a power take-off lever according to one embodiment of the disclosure. FIG. 16 is a schematic illustration of power output through a mechanically unlocking lever member according to one embodiment of the present disclosure.

In the present disclosure, as shown in fig. 15 and 16, the mechanical unlocking lever member 800 can also drive the power output lever 600 to rotate. Specifically, the mechanical unlocking lever member 800 includes a mechanical unlocking lever second feature 803, the mechanical unlocking lever second feature 803 being capable of being formed as one arm portion of the mechanical unlocking lever member 800, and the power output lever 600 includes an output lever first feature 603, the output lever first feature 603 being formed as a cylindrical boss protruding from one arm portion of the power output lever 600, and power transmission between the mechanical unlocking lever member 800 and the power output lever 600 being achieved by the arrangement of the cylindrical boss and the mechanical unlocking lever second feature 803.

Specifically, in the direction shown in fig. 6, when the mechanical unlocking lever member 800 is operated to rotate clockwise, it can push the power output lever 600 to rotate counterclockwise, thereby outputting power to the outside, and at this time, the power output lever 600 does not drive the middle lever member 700 to rotate. Accordingly, when the middle lever member 700 is rotated counterclockwise to drive the power take-off lever 600 to rotate counterclockwise, the power take-off lever 600 does not drive the mechanical unlocking lever member 800 to rotate.

Those skilled in the art will appreciate that when the lock apparatus for a sliding door does not include a manual unlocking function, i.e., does not include the mechanical unlocking lever member 800 described above, the power output lever 600 may not include the output lever first feature 603 described above.

FIG. 17 is a schematic structural view of a toggle member according to one embodiment of the present disclosure.

As shown in fig. 17, a striking device 401 is mounted on a driving gear part 400 of the lock device for sliding door of the present disclosure, the striking device 401 is capable of rotating with the rotation of the driving gear part 400, and the striking device 401 is capable of striking the first feature 101 of the tongue and rotating the tongue part 100 to realize the electric locking of the lock device for sliding door of the present disclosure. Preferably, the toggle device 401 is rotatable relative to the drive gear member 400, and the toggle device 401 and the drive gear member 400 have the same axis of rotation.

Fig. 18 is a schematic structural view of a pull-in release lever member according to one embodiment of the present disclosure. Fig. 19 is a schematic view of the mating relationship of the pull-up release lever member and the toggle member according to one embodiment of the present disclosure.

As shown in fig. 18 and 19, the lock device for a sliding door of the present disclosure may further include an engagement release lever member 920, the engagement release lever member 920 having a ninth rotation axis, wherein the ninth rotation axis is capable of coinciding with the sixth rotation axis. That is, the pull-in releasing lever member 920 may have the same rotation axis as the mechanical unlocking lever member 800, thereby facilitating the mechanical unlocking lever member 800 to drive the pull-in releasing lever member 920 to rotate.

Fig. 19 is a schematic structural view of a pull-in release lever member according to one embodiment of the present disclosure. FIG. 20 is a schematic illustration of the mating relationship of a pull-off lever member and a toggle member according to one embodiment of the present disclosure. Fig. 21 is a schematic view of an engagement release lever member driven to rotate according to one embodiment of the present disclosure.

As shown in fig. 19, the release lever assembly 920 of the present disclosure includes a release lever first feature 921 for engaging one arm of the mechanical release lever assembly 800 such that when the mechanical release lever assembly 800 is actuated to rotate clockwise, the mechanical release lever assembly 800 can actuate the release lever assembly 920 to move such that the release lever assembly 920 can release the striking device 401 and cause the striking device 401 to release the tongue assembly 100, and then, upon actuation of the pawl assembly 200, the tongue assembly 100 rotates and effects unlocking. In a specific embodiment, the un-engaged lever first feature 921 can be a stop extending from one arm of the un-engaged lever member 920.

On the other hand, the pull-up release lever member 920 includes a pull-up release lever second feature 922, the pull-up release lever second feature 922 being adapted to cooperate with the driving surface of the pawl driving lever 500 such that upon clockwise rotation of the pawl driving lever 500 (i.e., rotation of the pawl driving lever 500 toward the unlocked position) the pull-up release lever member 920 is actuated to rotate clockwise such that the pull-up release lever member 920 releases the striking device 401 and causes the striking device 401 to release the tongue member 100, and then upon actuation of the pawl member 200 the tongue member 100 rotates and effects unlocking. That is, at this time, when the lock device for a sliding door of the present disclosure is electrically unlocked, the pawl driving lever 500 thereof rotates, and at this time, the mechanical unlocking lever member 800 does not rotate, the pawl driving lever 500 is driven to rotate by the driving gear member 400, and further, the pawl driving lever 500 can drive the attraction releasing lever member 920 to rotate. In a particular embodiment, the un-engaged lever second feature 922 may be an arm of the un-engaged lever 921.

More specifically, the unlocking surface of the pawl driving lever 500 is a stepped surface, i.e., one arm portion of the pawl driving lever 500 is formed as a stepped portion having a stepped surface, and at least a portion of the engagement release lever second feature 922 is located within and in contact with the stepped portion of the pawl driving lever, whereby the pawl driving lever 500 is capable of driving the rotation of the engagement release lever member 920.

In the present disclosure, the end surface of one arm portion of the pull-up release lever member 920 is formed as an outwardly convex curved surface portion, i.e., the pull-up release lever third feature 923, and accordingly, as shown in fig. 18, the toggle 401 has a stop feature 402 having an inwardly concave curved shape, so that when the toggle 401 of the present disclosure is located at a certain position, e.g., the toggle 401 is in contact with the tongue first feature 101, and the tongue member 100 is in a first position, i.e., the lock device for a sliding door is in a locked state, the outwardly convex curved surface portion of the pull-up release lever member 920 can be rotated into the stop feature 402, whereby the pull-up release lever member 920 can limit the position of the toggle 401, i.e., limit the toggle 401, so that it cannot be rotated, and thereby limit the position of the tongue member 100.

That is, in the direction shown in fig. 20, when the driving gear part 400 rotates counterclockwise, it can drive the striking device 401 to rotate counterclockwise, and the left end of the engaging release lever part 920 can be located at a position above the striking device 401, and when the striking device 401 contacts the first locking bolt feature 101 and the locking bolt part 100 is in the first position, the engaging release lever part 920 can rotate counterclockwise by the restoring force of the restoring spring, and the outwardly protruding curved surface portion of the engaging release lever part 920 can rotate into the limiting feature 402.

Next, if the driving gear member 400 rotates counterclockwise, it does not drive the dial 401 to rotate synchronously, and the dial 401 is restrained in this position by the engaging release lever member 920. Only when the pull-in release lever member 920 is driven by the mechanical release lever member 800 or the pawl driving lever 500 and rotated clockwise, the outwardly protruding curved surface portion of the pull-in release lever member 920 is able to move out of the stop feature 402, and the toggle 401 returns to a state of abutting against one surface of the driving gear member 400 by the elastic restoring force, thereby allowing the latch bolt member 100 to be released.
