Description

Technical Field

[0001] The present disclosure relates to a lock device with power output, belonging to the technical field of motor vehicle locks. The lock device with power output is suitable for a sliding door of a motor vehicle. Background Art

[0002] Some motor vehicles in the prior art, such as commercial vehicles, include sliding doors, which are locked by a sliding door locking system.

[0003] Conventional sliding door locking systems primarily consist of a rear lock, a front lock, a full-open lock, and a transfer mechanism. The rear lock is located at the rear of the sliding door to lock the rear portion of the sliding door to the vehicle body; the front lock is located at the front of the sliding door to lock the front portion of the sliding door to the vehicle body; and the full-open lock is located at the bottom of the sliding door to lock the sliding door and the vehicle body when the sliding door is in the fully open position, ensuring that the sliding door remains in the fully open position.

[0004] When the sliding door needs to be opened, the rear lock provides power to the entire locking system via a relay mechanism, driving the rear and front locks to unlock, releasing the sliding door. When the sliding door is in the fully open position, the full-open lock engages, locking the sliding door to the vehicle body and keeping it fully open. When the door needs to be closed, the rear lock drives the full-open lock via a relay mechanism to unlock, releasing the sliding door and allowing it to close.

[0005] The existing technology requires a transfer mechanism to drive the front lock, full-open lock and rear lock respectively, which makes the transfer mechanism structure complicated. Unlocking the rear lock requires transferring power from the rear lock to the transfer mechanism and then transferring it back to the rear lock, resulting in a large efficiency loss, which reduces the ability of the rear lock to overcome the large sealing force.

[0091] Figure 1 It is a structural schematic diagram of a locking device with power output according to one embodiment of the present disclosure. Figure 2 3 is a schematic diagram of a locked state of a locking device with power output according to an embodiment of the present disclosure.

[0092] like Figure 1 As shown, the lock device with power output of the present disclosure may include a bolt component 100 , a pawl component 200 , a driving device 300 , a driving gear component 400 , a pawl driving rod 500 and other components.

[0093] The lock tongue component 100 has a first rotation axis and has a first locked position and a second locked position; wherein the first locked position can be a fully locked position, and the second locked position can be a partially locked position. In addition, the lock tongue component 100 can also include an unlocked position, in which the lock tongue component 100 can release the lock catch and realize the unlocking of the lock device with power output of the present disclosure.

[0094] That is, when the lock tongue component 100 is driven and rotated, the lock tongue component 100 can move to one of the first locking position, the second locking position and the unlocking position. Figure 2 In the direction shown, when the lock tongue component 100 is rotated counterclockwise, it can move from the first locking position to the second locking position, and when the lock tongue component 100 is further rotated counterclockwise, it can move from the second locking position to the unlocking position, thereby unlocking the lock device with power output. In the opposite working process, when the lock tongue component 100 is rotated clockwise, it can move from the unlocking position to the second locking position, and when the lock tongue component 100 is further rotated counterclockwise, it can move from the second locking position to the first locking position, thereby locking the lock device with power output of the present disclosure.

[0095] In a specific embodiment, the counterclockwise rotation of the lock tongue component 100 can be achieved by the reset force provided by components such as a reset spring, and the clockwise rotation of the lock tongue component 100 can be achieved by the driving gear component 400. This technical content will be described in detail below.

[0096] In the present disclosure, the pawl component 200 has a second rotation axis, and when the pawl component 200 is in the first position, the lock tongue component 100 is maintained in the first locking position; when the pawl component 200 is in the second position, the lock tongue component 100 is maintained in the second locking position. In one embodiment, the first position and the second position can be the same position or different positions.

[0097] Specifically, when the first position and the second position are the same, when unlocking, if the pawl component 200 is kept in a certain position, the lock tongue component 100 will be able to rotate from the first locked position to the unlocked position and will not be locked in the second locked position. On the other hand, when the first position and the second position are different, when unlocking, the lock tongue component 100 can be locked in the second locked position, and the pawl component 200 needs to be further driven to rotate the lock tongue component 100 from the second locked position to the unlocked position.

[0098] The opposite working process is that when locking, the locking tongue component 100 can be driven to rotate by cooperating with the first locking tongue feature 101 of the locking tongue component 100 through the driving gear component 400. At this time, when the locking tongue component 100 rotates from the unlocking position to the second locking position, the first pawl feature 201 of the pawl component 200 will cooperate with the outer surface of the locking tongue component 100 and slide into the second locking position. At this time, the pawl component 200 is located in the second position and can accordingly maintain the locking tongue component 100 in the second locking position; further, when the driving gear component 400 continues to rotate and pushes the locking tongue component 100 to rotate from the second locking position to the first locking position, the first pawl feature 201 of the pawl component 200 will continue to cooperate with the outer surface of the locking tongue component 100 and slide into the first locking position. At this time, the pawl component 200 is located in the first position. More preferably, the bolt first feature 101 is formed as an arm portion of the bolt component 100 , and the pawl first feature 201 is formed as an arm portion of the pawl component 200 .

[0099] Figure 3 It is a schematic structural diagram of a driving device according to one embodiment of the present disclosure.

[0100] like Figure 3As shown, the driving device 300 of the present disclosure may include a motor and a reducer connected to the motor, the reducer may be a worm gear reducer, and the output shaft of the worm gear reducer may be provided with a pinion, which can engage with the teeth of the driving gear component 400, so that the driving gear component 400 can have a larger output torque.

[0101] In the present disclosure, the driving gear component 400 may be an incomplete gear, for example, it may be a sector gear. When the driving gear component 400 is driven by the driving device 300, it has a third axis of rotation, and when the motor rotates forward and reverse, the driving gear component 400 can rotate in the first direction or in the second direction, wherein the first direction and the second direction are opposite directions. Moreover, when the driving gear component 400 rotates in the first direction, it can drive the lock tongue component 100 to rotate and lock the locking device with power output; when the driving gear component 400 rotates in the second direction, it can simultaneously drive the pawl drive rod 500 and the power output rod 600, so that the locking device with power output provides power to the outside while unlocking. More specifically, with Figure 1 As shown in the directions, the first direction is counterclockwise and the second direction is clockwise.

[0102] More specifically, if Figure 1 As shown, the pawl drive rod 500 has a fourth rotation axis, and the pawl drive rod 500 can be driven and rotated by the driving gear component 400, and the pawl component 200 is driven to rotate by the rotation of the pawl drive rod 500, so as to keep the lock tongue component 100 in the first locking position or the second locking position.

[0103] Specifically, the fourth rotation axis of the pawl drive lever 500 is located in the middle of the pawl drive lever 500, and the upper end of the pawl drive lever 500 is capable of receiving power, and the lower end of the pawl drive lever 500 cooperates with the pawl component 200 to rotate the pawl component 200. In one embodiment, the pawl component 200 includes a pawl second feature 202, which is capable of cooperating with the lower end of the pawl drive lever 500 (the third feature 503 of the drive lever) to enable the pawl drive lever 500 to drive the pawl component 200 to rotate.

[0104] In the present disclosure, the pawl drive lever 500 can also drive the pawl component 200 to a third position, in which the pawl component 200 can release the lock tongue component 100. Accordingly, the pawl drive lever 500 can rotate from the third position to the first position or the second position under the action of the reset force provided by a reset spring or the like. In other words, during the locking process of the power output lock device of the present disclosure, the pawl component 200 can rotate using the reset force provided by the reset spring to limit the position of the lock tongue component 100.

[0105] like Figure 1 As shown, the lock device with power output of the present disclosure further includes a power output rod 600 , which has a fifth rotation axis and can be driven by the driving gear component 400 so as to output power outwards through the power output rod 600 .

[0106] Figure 4 Schematic diagram of the power output process of a lock device with power output according to one embodiment of the present disclosure.

[0107] like Figure 1 and Figure 4 As shown, the power output rod 600 of the present disclosure includes a plurality of interface portions 601, wherein the interface portions 601 are used to connect to the plugs of the output cables 602, thereby providing power to the outside through the output cables 602. More preferably, the interface portions 601 are at different distances from the fifth rotation axis, so that the output cables 602 connected to the power output rod 600 have different movement strokes. Accordingly, the output cables 602 with longer movement strokes can be connected to the front lock, and the output cables 602 with shorter movement strokes can be connected to the fully unlocked lock, etc., thereby significantly reducing the complexity of the transfer mechanism, and even eliminating the transfer structure, thereby improving the transmission efficiency of the entire sliding door lock system. In a specific embodiment, the output cables 602 can be Bowden cables.

[0108] In a specific embodiment, the lock device with power output may further include an intermediate rod component 700, which can be driven and rotated by the driving gear component 400, and the rotation of the intermediate rod component 700 drives the power output rod 600 to rotate. In addition, the intermediate rod component 700 of the present disclosure is also used to drive the pawl drive rod 500 to rotate. That is, through the configuration of the intermediate rod component 700, when the driving gear component 400 drives the intermediate rod component 700 to rotate, the intermediate rod component 700 can synchronously drive the power output rod 600 and the pawl drive rod 500 to rotate, thereby unlocking each lock of the sliding door lock system.

[0109] Thus, by providing the intermediate rod component 700, the external power output and internal unlocking of the power output lock device of the present disclosure can be separated. The intermediate rod component 700 can directly drive the pawl drive rod 500 to achieve unlocking, thereby reducing the transmission path of the power output lock device (rear lock), improving efficiency, and enabling the power output lock device to overcome greater sealing forces. At the same time, the intermediate rod component 700 can drive the power output rod 600 to output two-way power, which can actuate other moving parts, such as the front lock and full lock of the sliding door lock system, thereby reducing the complexity of the transfer mechanism, improving stability, and even eliminating the transfer structure, thereby improving the transmission efficiency of the entire sliding door lock system.

[0110] In a preferred embodiment, the intermediate rod component 700 and the power output rod 600 have the same rotation axis. More specifically, the intermediate rod component 700 and the power output rod 600 can be arranged on the same hinge shaft and can both rotate relative to the hinge shaft.

[0111] Figure 5 2 is a schematic structural diagram of an intermediate rod component according to an embodiment of the present disclosure.

[0112] like Figure 5 As shown, the intermediate rod component 700 includes a first intermediate rod feature 701, which is configured to engage with the drive gear component 400, allowing the intermediate rod component 700 to be driven for rotation by the drive gear component 400. Specifically, the first intermediate rod feature 701 is formed as a cylindrical protrusion. One side surface of the drive gear component 400 can contact the outer circumference of the cylindrical protrusion, thereby driving the intermediate rod component 700 to rotate about the fifth rotation axis. Furthermore, the axis of the cylindrical protrusion is parallel to the fifth rotation axis and has a first predetermined distance therebetween. This ensures that when the drive gear component 400 applies a force to the intermediate rod component 700, the force has a moment arm of a predetermined length (equal to the predetermined distance).

[0113] Furthermore, the intermediate lever component 700 further includes an intermediate lever second feature 702, which is configured to cooperate with one end of the pawl drive lever 500 (the drive lever second feature 502), so that when the intermediate lever component 700 is driven to rotate by the drive gear component 400, the intermediate lever component 700 can drive the pawl drive lever 500 to rotate. Furthermore, the intermediate lever second feature 702 is formed as an arm portion of the intermediate lever component 700. For example, a second predetermined distance exists between the contact area between the intermediate lever second feature 702 and the pawl drive lever 500 and the fifth rotation axis. Preferably, the first predetermined distance is greater than the second predetermined distance.

[0114] The intermediate lever component 700 further includes a third intermediate lever feature 703, which is configured to engage with a side surface of the power output lever 600 to enable the intermediate lever component 700 to rotate the power output lever 600 when the intermediate lever component 700 is driven to rotate by the drive gear component 400. Furthermore, the third intermediate lever feature 703 is formed as a stopper protruding from the rotational plane of the intermediate lever component 700. More preferably, a third predetermined distance exists between the position where the stopper contacts the power output lever 600 and the fifth rotation axis, wherein the first predetermined distance is greater than the third predetermined distance.

[0115] That is to say, if Figure 1 In the direction shown, when the driving gear component 400 drives the intermediate rod component 700, the intermediate rod component 700 will rotate counterclockwise. Correspondingly, the power output rod 600 will rotate counterclockwise synchronously. At this time, the pawl driving rod 500 will rotate clockwise and drive the pawl component 200 to rotate counterclockwise to achieve unlocking.

[0116] In addition, the pawl drive rod 500 can also be reset by the reset force provided by the reset spring. This reset process is a counterclockwise movement process, thereby pushing the intermediate rod component 700 in the opposite direction, causing the intermediate rod component 700 to rotate clockwise and reset. Moreover, the intermediate rod component 700 can also be reset by the reset force provided by the reset spring or the like.

[0117] In the present disclosure, the lock device with power output can also be provided with a limit component, which can limit the intermediate rod component 700 to Figure 1 The initial position shown is to prevent the intermediate rod component 700 from crossing this position during the resetting process, thereby damaging the locking device with power output.

[0118] Figure 6 It is a structural schematic diagram of a locking device with power output according to another embodiment of the present disclosure.

[0119] like Figure 6 As shown, the lock device with power output disclosed in the present invention may also include a mechanical unlocking rod component 800, one end of which is connected to an input wire 801, and the driving force input by the input wire 801 is used to realize the rotation of the mechanical unlocking rod component 800, thereby realizing the mechanical unlocking of the lock device with power output; wherein, the mechanical unlocking rod component 800 has a sixth rotation axis, specifically, the connection between the input wire 801 and the mechanical unlocking rod component 800 is spaced apart from the sixth rotation axis of the mechanical unlocking rod component 800, so that the force applied to the mechanical unlocking rod component 800 by the input wire 801 can have a suitable lever arm.

[0120] The sixth rotation axis coincides with the fourth rotation axis, that is, the mechanical unlocking rod component 800 and the pawl drive rod 500 have the same rotation axis, thereby facilitating the parts arrangement of the lock device with power output disclosed herein and reducing the volume of the lock device with power output.

[0121] Specifically, when the mechanical unlocking lever component 800 rotates, it can directly or indirectly drive the pawl component 200 to rotate, thereby realizing the mechanical unlocking of the lock device with power output disclosed in the present invention. Figure 6 In the structure shown, the mechanical unlocking lever component 800 can selectively drive the pawl driving lever 500 to rotate, and indirectly drive the pawl component 200 to rotate through the pawl driving lever 500 .

[0122] In one embodiment of the present disclosure, the lock device with power output of the present disclosure also includes a child safety rod component 900, which can be driven to be in a first state or a second state, wherein when the child safety rod component 900 is in the first state, the mechanical unlocking rod component 800 can drive the pawl drive rod 500 to rotate, that is, the mechanical unlocking rod component 800 is allowed to drive the pawl drive rod 500; when the child safety rod component 900 is in the second state, the mechanical unlocking rod component 800 cannot drive the pawl drive rod 500 to rotate, that is, the mechanical unlocking rod component 800 is not allowed to drive the pawl drive rod 500 to rotate.

[0123] That is to say, the power output locking device disclosed in the present invention has a child safety function. Only when the child safety function is in an invalid state, that is, the child safety rod component 900 is in the first state, can the power output locking device disclosed in the present invention be unlocked by the mechanical unlocking rod component 800. On the other hand, when the child safety function is in an activated state, that is, the child safety rod component 900 is in the second state, it is not allowed to unlock the vehicle door by driving the mechanical unlocking rod component 800, so as to prevent the vehicle door from being unlocked by children without authorization, thereby improving the safety performance of the power output locking device.

[0124] Figure 7 2 is a schematic structural diagram of a pawl drive rod according to an embodiment of the present disclosure. Figure 8 2 is a schematic structural diagram of a mechanical unlocking lever component according to an embodiment of the present disclosure.

[0125] In this disclosure, Figure 7 and Figure 8As shown, the mechanical unlocking rod component 800 includes a mechanical unlocking rod first feature 802, and the pawl drive rod 500 includes a drive rod first feature 501. The motion plane of the mechanical unlocking rod first feature 802 is different from that of the drive rod first feature 501. In other words, the motion envelope of the drive rod first feature 501 disclosed in the present invention and the motion envelope of the mechanical unlocking rod first feature 802 do not overlap.

[0126] Moreover, the child safety rod component 900 is in the first state, including: at least a portion of the child safety rod component 900 cooperates with the first feature 802 of the mechanical unlocking rod, and at least a portion of the child safety rod component 900 cooperates with the first feature 501 of the drive rod, thereby enabling the driving force to be transmitted between the mechanical unlocking rod component 800 and the pawl drive rod 500 through the child safety rod component 900.

[0127] Figure 9 and Figure 10 It is a structural schematic diagram of a child safety bar component according to one embodiment of the present disclosure.

[0128] Specifically, if Figure 6 、 Figure 9 and Figure 10 As shown, one end of the child safety lever component 900 is rotatably mounted on the first feature 802 of the mechanical release lever, thereby providing the child safety lever component 900 with a seventh rotation axis. In the present disclosure, the seventh rotation axis is not a fixed axis and can change with the position of the first feature 802 of the mechanical release lever. The other end of the child safety lever component 900 is provided with a first feature 901 of the child safety lever, which can cooperate with the first feature 802 of the mechanical release lever and the first feature 501 of the drive lever.

[0129] On the other hand, the child safety lever component 900 is in the second state including: the first feature 901 of the child safety lever is away from the first feature 802 of the mechanical unlocking lever and the first feature 501 of the driving lever, thereby no transmission connection is formed between the mechanical unlocking lever component 800 and the pawl driving lever 500. At this time, even if the mechanical unlocking lever component 800 is pulled to rotate by the input pull wire 801, the mechanical unlocking lever component 800 will not drive the pawl driving lever 500 to rotate, and accordingly, the locking device with power output will not be unlocked.

[0130] The mechanical release lever first feature 802 includes a force-applying surface, and the drive lever first feature 501 includes a force-receiving surface. The force-applying surface is capable of applying a force to the child-safety lever first feature 901, and transmitting the force to the force-receiving surface of the drive lever first feature 501 through the child-safety lever first feature 901, thereby achieving force transmission between the mechanical release lever component 800 and the pawl drive lever 500. More preferably, the child-safety lever first feature 901 includes a surface that cooperates with the force-applying surface and a surface that cooperates with the force-receiving surface, and the force-applying surface is formed as an outwardly convex curved surface, and the force-receiving surface is formed as an inwardly concave surface, so that when the child-safety lever first feature 901 is located between the mechanical release lever first feature 802 and the drive lever first feature 501, it will not easily slip out of this position.

[0131] Figure 11 and Figure 12 It is a structural schematic diagram of a child safety unlocking lever component according to an embodiment of the present disclosure.

[0132] like Figures 9 to 12 As shown, the child safety lever component 900 of the present disclosure includes a child safety lever second feature 902 , wherein the child safety lever second feature 902 can be operated by a child safety unlocking lever component 910 to place the child safety lever component 900 in a first state or a second state.

[0133] In one embodiment, the child safety release lever 910 is operable to rotate about one end of the child safety release lever 910. For example, the child safety release lever 910 has an eighth rotation axis that is parallel to and non-coincident with the seventh rotation axis. In other words, even if the position of the seventh rotation axis changes with the first feature 802 of the mechanical release lever, the eighth rotation axis and the seventh rotation axis do not coincide at all positions.

[0134] Figure 13 3 is a structural schematic diagram of a child safety bar component in a first state according to an embodiment of the present disclosure. Figure 14 3 is a schematic structural diagram of a child safety bar component in a second state according to an embodiment of the present disclosure.

[0135] The child safety unlocking lever component 910 includes a guide groove 911, and the second feature 902 of the child safety lever is configured to be able to slide along the guide groove 911, so that when the child safety unlocking lever component 910 is rotated in the first direction ( Figure 13 or Figure 14 When the child safety lever is rotated (in the clockwise direction shown in FIG. 1 ), the second feature 902 of the child safety lever can be slidably guided by the guide groove 911, and the child safety lever component 900 is rotated (in the clockwise direction shown in FIG. 1 ). Figure 13 or Figure 14The first feature 901 of the child-safety lever is moved from a position away from the mechanical unlocking lever component 800 and the pawl driving lever 500 to a position between the mechanical unlocking lever component 800 and the pawl driving lever 500. At this time, the child-safety function is disabled and can be unlocked by the mechanical unlocking lever component 800. Furthermore, if the mechanical unlocking lever component 800 is operated at this time, the first feature 901 of the child-safety lever will continue to slide in the guide groove 911. At this time, this section of the guide groove is set to be an arc centered on the sixth rotation axis, thereby ensuring that the first feature 901 of the child-safety lever will not be separated from between the first feature 802 of the mechanical unlocking lever and the first feature 501 of the driving lever.

[0136] The reverse working process occurs when the child safety unlocking lever component 910 rotates in the second direction ( Figure 13 or Figure 14 When the child safety lever is rotated (in the counterclockwise direction shown), the second feature 902 of the child safety lever can be slidably guided by the guide groove 911, and the child safety lever component 900 is rotated ( Figure 13 or Figure 14 The first feature 901 of the child safety lever moves from a position between the mechanical unlocking lever component 800 and the pawl drive lever 500 to a position away from the mechanical unlocking lever component 800 and the pawl drive lever 500. At this time, the child safety function is activated. At this time, even if the mechanical unlocking lever component 800 is rotated, the pawl drive lever 500 will not be driven to rotate, so that unlocking cannot be achieved by the mechanical unlocking lever component 800.

[0137] Figure 15 It is a schematic structural diagram of a power output rod according to one disclosed embodiment. Figure 16 It is a schematic diagram of achieving power output through a mechanical unlocking lever component according to one embodiment of the present disclosure.

[0138] In this disclosure, Figure 15 and Figure 16 As shown, the mechanical unlocking lever component 800 can also drive the above-mentioned power output lever 600 to rotate. Specifically, the mechanical unlocking lever component 800 includes a mechanical unlocking lever second feature 803, which can be formed as an arm of the mechanical unlocking lever component 800; and the power output lever 600 includes an output lever first feature 603, which can be formed as a cylindrical protrusion protruding from an arm of the power output lever 600. The cylindrical protrusion and the mechanical unlocking lever second feature 803 are arranged to realize power transmission between the mechanical unlocking lever component 800 and the power output lever 600.

[0139] Specifically, Figure 6In the direction shown, when the mechanical unlocking lever component 800 is operated to rotate clockwise, it can push the power output lever 600 to rotate counterclockwise, thereby outputting power outward. At this time, the power output lever 600 does not drive the intermediate lever component 700 to rotate. Correspondingly, when the intermediate lever component 700 rotates counterclockwise to drive the power output lever 600 to rotate counterclockwise, the power output lever 600 does not drive the mechanical unlocking lever component 800 to rotate.

[0140] Those skilled in the art should know that when the lock device with power output does not include a manual unlocking function, that is, does not include the above-mentioned mechanical unlocking lever component 800, the power output lever 600 may also not include the above-mentioned output lever first feature 603.

[0141] Figure 17 It is a structural schematic diagram of a toggle component according to one embodiment of the present disclosure.

[0142] like Figure 17 As shown, the driving gear component 400 of the power output lock device of the present disclosure is equipped with a toggle device 401. The toggle device 401 can rotate with the rotation of the driving gear component 400, and the toggle device 401 can toggle the first feature 101 of the lock tongue and cause the lock tongue component 100 to rotate, thereby achieving the electric locking of the power output lock device of the present disclosure. Preferably, the toggle device 401 can rotate relative to the driving gear component 400, and the toggle device 401 and the driving gear component 400 have the same rotation axis.

[0143] Figure 18 2 is a schematic structural diagram of a suction release lever component according to one embodiment of the present disclosure. Figure 19 It is a schematic diagram of the cooperation relationship between the suction release lever component and the toggle component according to one embodiment of the present disclosure.

[0144] like Figure 18 and Figure 19 As shown, the lock device with power output of the present disclosure may further include a pull-out lever component 920 having a ninth rotation axis, wherein the ninth rotation axis can coincide with the sixth rotation axis. In other words, the pull-out lever component 920 can have the same rotation axis as the mechanical unlocking lever component 800, thereby facilitating the mechanical unlocking lever component 800 to drive the pull-out lever component 920 to rotate.

[0145] Figure 19 2 is a schematic structural diagram of a suction release lever component according to one embodiment of the present disclosure. Figure 20 It is a schematic diagram of the cooperation relationship between the suction release lever component and the toggle component according to one embodiment of the present disclosure. Figure 212 is a schematic diagram of a suction release lever component being driven to rotate according to one embodiment of the present disclosure.

[0146] like Figure 19 As shown, the suction release lever component 920 of the present disclosure includes a suction release lever first feature 921, which is used to cooperate with an arm of the mechanical unlocking lever component 800, so that when the mechanical unlocking lever component 800 is driven to rotate clockwise, the mechanical unlocking lever component 800 can drive the suction release lever component 920 to move, thereby allowing the suction release lever component 920 to release the toggle device 401, and causing the toggle device 401 to release the lock tongue component 100; then, under the drive of the pawl component 200, the lock tongue component 100 rotates and unlocking is achieved. In a specific embodiment, the suction release lever first feature 921 can be a limit block extending from one arm of the suction release lever component 920.

[0147] On the other hand, the suction release lever component 920 includes a suction release lever second feature 922, which is used to cooperate with the driving surface of the pawl drive lever 500, so that when the pawl drive lever 500 rotates clockwise, it can drive the suction release lever component 920 to rotate clockwise, thereby allowing the suction release lever component 920 to release the toggle device 401 and the toggle device 401 to release the lock tongue component 100; then, under the drive of the pawl component 200, the lock tongue component 100 rotates and unlocking is achieved. That is, at this time, when the lock device with power output of the present disclosure is electrically unlocked, its pawl drive lever 500 rotates, and at this time the mechanical unlocking lever component 800 does not rotate. The pawl drive lever 500 is driven to rotate by the driving gear component 400, and further, the pawl drive lever 500 can drive the suction release lever component 920 to rotate. In a specific embodiment, the second feature 922 of the suction release lever can be an arm portion of the suction release lever 921 .

[0148] More specifically, the unlocking surface of the pawl drive rod 500 is a step surface, that is, one arm portion of the pawl drive rod 500 is formed as a step portion, and the step portion has a step surface. At least part of the second feature 922 of the attraction release rod is located in the step portion of the pawl drive rod and contacts the step surface of the step portion, thereby the pawl drive rod 500 can drive the attraction release rod component 920 to rotate.

[0149] In the present disclosure, the end surface of one arm of the suction release lever component 920 is formed as a curved surface protruding outward, and the curved surface protruding outward is the third feature 923 of the suction release lever; accordingly, Figure 18As shown, the toggle device 401 has a limiting feature 402, which is an inwardly concave curved surface. Therefore, when the toggle device 401 of the present invention is located at a certain position, for example, the toggle device 401 is in contact with the first feature 101 of the lock tongue, and the lock tongue component 100 is in the first position, that is, when the lock device with power output is in the locked state, the outward protruding curved surface portion of the suction release lever component 920 can be rotated into the limiting feature 402. Thus, the suction release lever component 920 can limit the position of the toggle device 401, that is, limit the toggle device 401 so that it cannot rotate, and thereby limit the position of the lock tongue component 100.

[0150] That is to say, Figure 20 In the direction shown, when the driving gear component 400 rotates counterclockwise, it can drive the toggle device 401 to rotate counterclockwise. At this time, the left end of the suction release lever component 920 can be located at a certain position above the toggle device 401; when the toggle device 401 contacts the first feature 101 of the lock tongue and the lock tongue component 100 is in the first position, the suction release lever component 920 can rotate counterclockwise under the action of the reset force of the reset spring, and the outward protruding curved portion of the suction release lever component 920 can rotate into the limiting feature 402.

[0151] Next, if the driving gear component 400 rotates counterclockwise, it will not drive the toggle device 401 to rotate synchronously, and the toggle device 401 will be restricted in this position by the suction release lever component 920. Only when the suction release lever component 920 is driven by the mechanical unlocking lever component 800 or the pawl driving lever 500 and rotates clockwise, the outwardly protruding curved surface portion of the suction release lever component 920 can be moved out of the said limiting feature 402, and the toggle device 401 will return to a state of being closely attached to a surface of the driving gear component 400 under the action of the elastic restoring force, thereby releasing the lock tongue component 100.
