[0101] The third feature 4023 of the mechanical release lever and the fourth feature 4024 of the mechanical release lever are respectively used to hook the cable wires in different directions, thereby realizing the arrangement of the cables in different directions, providing flexibility in the arrangement of the electric suction locking device 1000 and the cables.

[0102] The fifth feature 4025 of the mechanical release lever is used to cooperate with the base plate 300 to achieve the limiting of the release assembly 400.

[0103] The mechanical release lever 402 of the electric suction lock device 1000 of this embodiment can simultaneously actuate the pawl 201 to unlock and actuate the suction member of the lifting suction assembly 500 to disengage from the engagement with the lock tongue 101 .

[0104] The electric release lever 401 and mechanical release lever 402 of the electric suction lock device 1000 of this embodiment are configured as follows: the electric release lever 401 is used to receive the driving force of the electric actuator to actuate the pawl 201 to disengage from the lock tongue 101. The mechanical release lever 402 is used to receive the manual operating force to drive the pawl 201 to disengage from the lock tongue 101. When the mechanical release lever 402 moves, it can drive the electric release lever 401 to follow the movement; however, when the electric release lever 401 moves, it cannot drive the mechanical release lever 402 to follow the movement.

[0105] refer to Figure 6 The release assembly spring 403 of the present disclosure has a pre-tightening force, so that the release assembly spring 403 can load an elastic force to the release assembly 400, and the elastic force makes the release assembly 400 have a tendency to rotate from the actuated position to the initial position.

[0106] Figure 6 The installation method of the release component spring 403 is shown by way of example. In light of the technical solution disclosed herein, those skilled in the art can adjust the installation method of the release component spring 403, the specific type of the release component spring 403, etc., all of which fall within the scope of protection of the present disclosure.

[0107] Figures 9 to 11 1 is a schematic structural diagram of a lifting and sucking assembly 500 of an electric sucking lock device 1000 according to an embodiment of the present disclosure.

[0108] refer to Figures 9 to 11 The lifting and sucking assembly 500 of the electric sucking lock device 1000 of this embodiment includes a lifting member 501, a sucking member 502, a lifting member spring 503 and a sucking member spring 504.

[0109] refer to Figure 10The lifting member 501 of the present disclosure is a component that can rotate about an axis ("+" position). The lifting member 501 of the present disclosure is provided with a lifting surface 5011, which directly cooperates with the lock catch. When the lock tongue 101 is released, the lifting member 501 can use the lifting surface 5011 to push the lock catch from the main locking position to the open position. Preferably, the lifting and engaging assembly 500 and the lock tongue assembly 100 of the present disclosure are independent components.

[0110] Continue to refer Figure 10 The lifting member 501 of the present disclosure is also provided with a first lifting member hole 5012, a lifting member hook feature 5013, a lifting member flange feature 5014 and a lifting member second hole 5015.

[0111] The first hole 5012 of the lifting member is used to connect to an electric actuator (e.g., a pull wire of the electric actuator), thereby receiving the force and movement of the electric actuator. The hook-shaped feature 5013 of the lifting member is used to connect to the lifting member spring 503 to provide sufficient lifting force. The flange feature 5014 of the lifting member is used to cooperate with the housing assembly 700 to achieve the position limit of the lifting member 501. The second hole 5015 of the lifting member is used to install the suction member 502.

[0112] refer to Figure 11 The present disclosure designs the structure of the suction member, and the suction member 502 can actuate the lock tongue 101 to move from the secondary closed position to the primary closed position. Preferably, the suction member 502 is rotatably disposed on the lifting member 501 via the second hole 5015 of the lifting member.

[0113] Continue to refer Figure 11 The suction member 502 of the present disclosure is provided with a first suction member feature 5021 and a second suction member feature 5022 .

[0114] The first feature 5021 of the suction member is used to engage with the third feature 1013 of the lock tongue, so that the suction member 502 can drive the lock tongue 101 to move from the open position to the main closed position through the first feature 5021 of the suction member, thereby realizing electric suction.

[0115] Preferably, the first feature 5021 of the suction component is constructed as follows: during the suction process, when the lock tongue 101 is prevented by an obstacle from moving toward the main closed position to a position where it can engage with the first feature 5021 of the suction component, the first feature 5021 of the suction component cannot engage with the third feature 1013 of the lock tongue; when the lock tongue 101 can move toward the main closed position to a position where it can engage with the first feature 5021 of the suction component, the first feature 5021 of the suction component can engage with the third feature 1013 of the lock tongue and actuate the lock tongue 101 to move from the secondary closed position to the main closed position.

[0116] The second feature 5022 of the suction member 502 of the present disclosure is used to cooperate with the housing assembly 700 to control the engagement and disengagement of the first feature 5021 of the suction member and the third feature 1013 of the lock tongue. At the same time, when the mechanical release lever 402 is operated to actuate the pawl 201 to unlock, the mechanical release lever 402 can push the first feature 5021 of the suction member to disengage from the third feature 1013 of the lock tongue through the second feature 4022 of the mechanical release lever.

[0117] refer to Figure 9 The lifting member spring 503 and the attracting member spring 504 of the present disclosure both have a preload force, enabling the lifting member spring 503 to apply an elastic force to the lifting member 501. This elastic force causes the lifting member 501 to tend to push the lock catch from the main locked position toward the open position. The attracting member spring 504 can apply an elastic force to the attracting member 502, causing the first feature 5021 of the attracting member to tend to move toward engagement with the third feature 1013 of the lock tongue.

[0118] Figure 9 The installation method of the lifting member spring 503 and the suction member spring 504 is shown by way of example. In light of the technical solution disclosed herein, those skilled in the art can adjust the installation method of the lifting member spring 503 and the suction member spring 504, the specific types of the lifting member spring 503 and the suction member spring 504, etc., all of which fall within the scope of protection of the present disclosure.

[0119] Figures 12 to 14 Schematic diagram of the structure of the clutch assembly 600 of the electric suction lock device 1000 according to one embodiment of the present disclosure.

[0120] refer to Figures 12 to 14 The clutch assembly 600 of the electric suction lock device 1000 disclosed in the present invention includes a clutch actuator 601 , a clutch driving member 602 , a clutch return spring 603 and a clutch driving spring 604 .

[0121] The clutch assembly 600 of the present disclosure is movable between an operative position and an inoperative position. When the clutch assembly 600 is in the operative position, movement of the release assembly 400 to the actuated position can only drive the pawl 201 to the secondary locked position; when the clutch assembly 600 is in the inoperative position, movement of the release assembly 400 to the actuated position can drive the pawl 201 to the unlocked position.

[0122] Continue to refer Figures 12 to 14 The clutch driving member 602 and the clutch executing member 601 of the clutch assembly 600 of the electric suction lock device 1000 of the present disclosure are constructed as follows:

[0123] When the locking tongue 101 leaves the main closed position, the clutch driving member 602 can drive the clutch actuator 601 to leave the operating position and enter the non-operating position.

[0124] When the lock tongue 101 enters the main closed position, the lock tongue 101 can actuate the clutch drive 602 to drive the clutch actuator 601, so that the clutch actuator 601 returns to the operating position. Preferably, the clutch drive 602 and the clutch actuator 601 are rotatably arranged on the base plate 300 ("+" is the position of the rotation axis).

[0125] refer to Figure 12 and Figure 13 The clutch actuator 601 of the present disclosure is provided with a clutch actuator hook portion 6011 (first end) and a clutch actuator protruding feature 6012 (second end).

[0126] The clutch actuator hook portion 6011 is configured to engage with the second feature 4012 of the electric release lever. When the clutch actuator 601 is in the operating position, the clutch actuator hook portion 6011 engages with the second feature 4012 of the electric release lever, restricting the release assembly 400 from actuating the pawl 201 to the secondary locked position. When the clutch actuator 601 is in the non-operating position, the clutch actuator hook portion 6011 disengages from the second feature 4012 of the electric release lever, releasing the restriction on the release assembly 400 and enabling the release assembly 400 to actuate the pawl 201 to the unlocked position. Preferably, the clutch actuator hook portion 6011 releases the clutch actuator 601, returning it to the non-operating position, only after the second feature 4012 of the electric release lever has disengaged from the hook groove of the clutch actuator hook portion 6011.

[0127] The clutch actuator protruding feature 6012 is used to cooperate with the clutch driving member 602 so that the clutch driving member 602 drives the clutch actuator 601 to leave or enter the operating position.

[0128] refer to Figure 14 The clutch driving member 602 of the present disclosure is provided with a first clutch driving member feature 6021 , a second clutch driving member feature 6022 and a third clutch driving member feature 6023 .

[0129] Among them, the first feature 6021 of the clutch drive is used to cooperate with the fourth feature 1014 of the lock tongue. When the lock tongue 101 enters the main closed position, the lock tongue 101 drives the clutch drive 602 through the fourth feature 1014 of the lock tongue, and then actuates the clutch actuator 601 to enter the operating position.

[0130] When the lock tongue 101 leaves the main closed position, the clutch actuator 601 leaves the operating position under the action of the clutch drive spring 604, thereby disengaging the clutch actuator hook portion 6011 from the electric release lever 401. The clutch actuator second feature 6022 is used to engage the clutch drive spring 604. The clutch actuator third feature 6023 is used to cooperate with the clutch actuator protruding feature 6012 to drive the clutch actuator 601 out of or into the operating position.

[0131] refer to Figure 12 The clutch return spring 603 and clutch drive spring 604 of the present disclosure have a preload force, allowing the clutch return spring 603 to apply an elastic force to the clutch actuator 601. This elastic force enables the clutch actuator 601 to move along with the clutch drive 602 ("+" represents the position of the rotation axis). The clutch drive spring 604 can apply an elastic force to the clutch drive 602, allowing the clutch drive 602 to actuate the clutch actuator 601 to leave the operating position.

[0132] Figure 12 The installation method of the clutch reset spring 603 and the clutch drive spring 604 is shown by way of example. In light of the technical solution disclosed herein, those skilled in the art can adjust the installation method, specific type, etc. of the clutch reset spring 603 and the clutch drive spring 604, all of which fall within the scope of protection of the present disclosure.

[0133] Figure 15 1 is a schematic structural diagram of a housing assembly 700 of an electric suction lock device 1000 according to an embodiment of the present disclosure.

[0134] refer to Figure 15 The housing assembly 700 of the electric suction lock device 1000 disclosed in the present invention includes a housing 701 , a bolt assembly signal device 702 and a pawl assembly signal device 703 .

[0135] Continue to refer Figure 15 The housing 701 of the present disclosure is provided with a first housing feature 7011 , a second housing feature 7012 , a housing connector 7013 and a housing buffer block 7014 .

[0136] Among them, the first feature 7011 of the shell is used to cooperate with the second feature 5022 of the suction component, so that the first feature 5021 of the suction component can engage or disengage with the third feature 1013 of the lock tongue, thereby enabling the lifting suction component 500 to disengage or engage with the lock tongue 101.

[0137] The second housing feature 7012 is used to cooperate with the lifting member flange feature 5014 to achieve the limit of the lifting member 501. The housing connector 7013 is used to connect to the vehicle wiring harness to transmit the status signal of the lock tongue assembly signal device 702 and the status signal of the pawl assembly signal device 703 to the vehicle controller.

[0138] Continue to refer Figure 15 The bolt assembly signaling device 702 of the present disclosure changes its signal state when the bolt 101 approaches or enters the secondary closed position during the process of the bolt 101 moving from the open position to the primary closed position of the bolt 101. The pawl assembly signaling device 703 of the present disclosure changes its signal state when the pawl 201 and the bolt 101 change from a disengaged state to an engaged state at the first locked position, thereby instructing the pawl 201 to maintain the bolt 101 in the primary locked position.

[0139] Preferably, the pawl assembly signal device 703 and the lock tongue assembly signal device 702 of the present invention are both arranged on the shell 701. The shell 701 is preferably fixed with the required wiring harness by injection molding, and is connected to the vehicle wiring harness through the shell connector 7013 to transmit the status signal of the lock tongue assembly signal device 702 and the status signal of the pawl assembly signal device 703 to the vehicle controller.

[0140] Continue to refer Figure 15 The shell buffer block 7014 of the present disclosure can provide buffering for the lock when the lock is locked into the main closed position.

[0141] Figure 16 Schematic diagram of the cover plate 800 of the electric suction lock device 1000 according to one embodiment of the present disclosure.

[0142] refer to Figure 16 The cover plate 800 of the electric suction lock device 1000 of the present disclosure is provided with a first cover plate feature 8001 and a second cover plate feature 8002 .

[0143] The first feature 8001 of the cover is used to snap into the housing 701 to increase the strength of the housing 701. The second feature 8002 of the cover is used to provide a snap-fit ​​structure for the cable of the lifting and attracting assembly 500, transmitting the power and movement of the electric actuator to the lifting and attracting assembly 500.

[0144] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure also includes a first electric actuator, and the driving force of the first electric actuator can be transmitted to the electric release rod 401, so that the electric release rod 401 can actuate the pawl 201 to disengage from the lock tongue 101, thereby realizing electric unlocking of the electric suction lock device 1000.

[0145] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure also includes a second electric actuator, and the driving force of the second electric actuator can be transmitted to the lifting member 501, and the lifting member 501 drives the suction member 502 to move. When the lock tongue 101 can move toward the main closed position, the suction member 502 can engage with the lock tongue 101, thereby realizing the electric suction of the locking device.

[0146] In some embodiments of the present disclosure, the first electric actuator and the second electric actuator may be the same actuator.

[0147] The electric release lever 401 of the present disclosure can be connected to the first electric actuator described above via a Bowden cable. The suction member 502 can also be connected to the second electric actuator via a Bowden cable. Preferably, the Bowden cable interface of the electric release lever 401 and the Bowden cable interface of the suction member 502 are arranged on the same side of the locking device.

[0148] The first electric actuator and the second electric actuator can adopt the electric actuators in Chinese patent CN202010283886.0, Chinese patent CN202020530719.7, Chinese patent CN202111476814.9 or other similar structures, which will not be repeated in this disclosure.

[0149] In some other embodiments of the present disclosure, the first electric actuator, the second electric actuator, and the electric suction locking device 1000 may be integrated into a whole, thereby reducing costs.

[0150] Figures 17 to 24 Schematic diagram of the electric release process of the electric suction lock device 1000 according to one embodiment of the present disclosure.

[0151] refer to Figure 17 and Figure 18 The bolt 101 of the electric suction lock device 1000 of the present disclosure is in the main closed position, and the pawl 201 is in the main locked position. The bolt assembly signal device 702 and the pawl assembly signal device 703 are both in the untriggered state. The electric release lever 401 is not in the actuated position.

[0152] refer to Figure 19When the release assembly 400 is first operated to the actuated position, the electric release lever 401 will push the pawl 201 away from the primary locking position. Due to the constraint of the hook portion 6011 of the clutch actuator, the electric release lever 401 can only push the pawl 201 to the secondary locking position. At this time, under the action of the lifting member 501, the lifting member 501 drives the suction member 502 to move, and the suction member 502 drives the lock tongue 101, and the lock tongue 101 will move toward the secondary closed position, thereby pushing the lock to move toward the opening direction. Since the pawl 201 is in the secondary locking position, the lock tongue 101 will be locked in the secondary closed position by the pawl 201. Figure 20 As shown, at this time, the pawl assembly signal device 703 is triggered, indicating that the electric suction locking device 1000 has been unlocked.

[0153] refer to Figure 21 When the electric release lever 401 is released, the electric release lever 401 will return to the initial position (i.e., the non-actuated position) under the action of the release assembly spring 403. Since the lock tongue 101 has left the main closed position at this time, the lock tongue 101 (the fourth feature 1014 of the lock tongue) releases the constraint on the clutch drive member 602 (the first feature 6021 of the clutch drive member). Under the action of the clutch drive spring 604 and the clutch return spring 603, the clutch actuator 601 will leave the operating position ( Figure 21 The clutch actuator 601 rotates clockwise under the action of the clutch driving member 602), thereby releasing the constraint of the clutch actuator hook portion 6011 on the electric release lever 401. When the electric release lever 401 is operated again, the clutch actuator hook portion 6011 releases the constraint on the electric release lever 401, and the electric release lever 401 can push the pawl 201 from the secondary locking position to the unlocking position, so that the lock tongue 101 can move from the secondary closed position to the open position. Figure 22 shown.

[0154] like Figure 22 and Figure 23 As shown, when the pawl 201 is pushed to the unlocked position, the lock tongue 101 can move from the secondary closed position to the open position. At this time, under the action of the lifting member 501, the lock tongue 101 will move toward the open position, thereby pushing the lock catch toward the opening direction. When the lifting member flange feature 5014 contacts the second feature 7012 of the housing, the lifting member 501 is restrained and no longer pushes the lock catch toward the opening direction. At this time, the lock tongue assembly signal device 702 is still not triggered, indicating that the lock tongue 101 has not reached the fully open position.

[0155] like Figure 24 As shown, when the lock catch is pushed by an external force and drives the lock tongue 101 to reach the fully open position, the lock tongue assembly signal device 702 is triggered, indicating that the lock tongue 101 has reached the fully open position. At this time, the electric suction lock device 1000 is in the fully open state.

[0156] Figures 25 to 30 Schematic diagram of the electric suction process of the electric suction lock device 1000 according to one embodiment of the present disclosure.

[0157] refer to Figure 25 When the lock moves downward, the lock will push the lock tongue 101 from the open position to the secondary closed position. When the lock and the lifting member 501 come into contact, the lock tongue assembly signal device 702 is triggered. At this time, the electric actuator starts to move under the control of the vehicle controller, pulling the lifting member 501 to move toward the main closed position.

[0158] like Figure 26 As shown, the suction member 502 will move with the lifting member 501. When the suction member 502 moves to the point where the second feature 5022 of the suction member is free from the constraint of the first feature 7011 of the shell, the suction member 502 will move toward the direction of the third feature 1013 of the lock tongue under the action of the suction member spring 504.

[0159] like Figure 27 As shown, when the lock tongue 101 is blocked by an obstacle (such as a hand) and cannot fall under the action of gravity, the first feature 5021 of the suction member cannot lock into the third feature 1013 of the lock tongue, so that the lifting member 501 cannot push the lock tongue 101 toward the main closed position, thereby realizing obstacle prevention.

[0160] like Figure 28 As shown, when the lock tongue 101 can fall under the action of gravity, the first feature 5021 of the suction member can lock into the third feature 1013 of the lock tongue, so that the lifting member 501 can push the lock tongue 101 toward the main closed position to achieve electric suction.

[0161] like Figure 29 and Figure 30 As shown, as the lock tongue 101 is pushed to the main closed position, the pawl 201 can enter the main locked position, and the pawl assembly signal device 703 is released, thereby completely locking the electric suction lock device 1000. At the same time, the lock tongue fourth feature 1014 actuates the clutch driver first feature 6021, causing the clutch driver 602 to drive the clutch actuator 601 into the operating position, so that the clutch actuator hook portion 6011 can once again restrict the travel of the electric unlocking lever 401.

[0162] Figures 31 to 33 Schematic diagram of the mechanical unlocking process of the electric suction lock device 1000 according to one embodiment of the present disclosure.

[0163] refer to Figures 31 to 33When the mechanical release lever 402 moves in operation direction 1 or operation direction 2, the mechanical release lever 402 will push the electric unlocking lever 401 to move together, so that after undergoing the same action as the aforementioned electric unlocking, the electric suction lock device 1000 can be mechanically unlocked. At the same time, the second feature 4022 of the mechanical release lever will push the second feature 5022 of the suction member so that the first feature 5021 of the suction member disengages from the lock tongue 101, thereby achieving the disengagement of the suction member 502 from the lock tongue 101. Even in special circumstances such as when the electric actuator is powered off during the suction process, the electric suction lock device 1000 can still be mechanically released through the mechanical release lever 402. Figure 32 and Figure 33 shown.

[0164] refer to Figures 34 to 42 On the basis of the electric suction lock device described above, the technical solution is adjusted. The present disclosure also provides an electric suction lock device with the following technical solution. It should be noted that the lock tongue assembly 100 and its sub-components, the pawl assembly 200 and its sub-components, the release assembly 400 and its sub-components, the lifting suction assembly 500 and its sub-components, the clutch assembly 600 and its sub-components described above, and other structures not described in detail below, can also be used in the electric suction lock device described below. The following focuses on the contents involved in the technical solution adjustment.

[0165] refer to Figures 1 to 42 Especially Figures 34 to 42 In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure includes:

[0166] The lock tongue 101 has a first locking position 1011 and a second locking position 1012. Based on the first locking position 1011 and the second locking position 1012, the lock tongue 101 can move between a main closed position, a secondary closed position and an open position;

[0167] The pawl 201 can move between a primary locking position, a secondary locking position, and an unlocked position. In the primary locking position, the pawl 201 engages with the first locking position 1011 of the lock tongue 101 to lock the lock tongue 101 in the primary closed position. In the secondary locking position, the pawl 201 engages with the second locking position 1012 of the lock tongue 101 to lock the lock tongue 101 in the secondary closed position.

[0168] The bottom plate 300, the lock tongue 101 and the pawl 201 are rotatably disposed on the bottom plate 300;

[0169] A lifting member 501 (also known as a lifting rod), when the lock tongue 101 is released by the pawl 201, the lifting member 501 pushes the lock tongue 101 from the main closed position to the open position via the lock catch;

[0170] The suction member 502 can actuate the locking tongue 101 to move from the secondary closing position to the primary closing position.

[0171] In the locking process, the lifting member 501 is driven before the lock tongue 101. When the lifting member 501 is driven to the predetermined position ( Figure 35 ), the lock tongue 101 is driven to move toward the secondary closing position, and the suction member 502 drives the lock tongue 101 that has reached the secondary closing position to drive it to the main closing position.

[0172] The technical solution of this embodiment, by configuring the lifting member 501 to be driven to the predetermined lifting member position before the lock tongue 101, can reduce the driving force required to drive the lock tongue 101 to the secondary closed position (i.e., the position waiting for suction), thereby improving the reliability of the electric suction lock device 1000. The lock tongue 101 can be driven by the lock buckle to move from the open position to the secondary closed position.

[0173] In some embodiments of the present disclosure, when the control circuit board of the electric suction lock device 1000 receives a locking signal (the locking signal may come from a remote control key or a trigger button on the front cover of the car), the lock latch drives the lock tongue 101 under the driving force from the motor (i.e., external force), so that the lock tongue 101 moves from the open position to the secondary closed position ( Figure 36 state shown) movement.

[0174] In other embodiments of the present disclosure, the external force described above for driving the lock may be a mechanical operating force, such as a pressing operating force on the front hood (front hatch) of a car, which drives the lock, thereby driving the lock tongue 101 and causing the lock tongue to move to the secondary closed position.

[0175] Furthermore, in some embodiments of the present disclosure, the electric suction lock device 1000 further includes: a lifting member position switch 505. When the lifting member 501 is driven to the lifting member predetermined position, the lifting member 501 triggers the lifting member position switch 505 to generate a signal indicating that the lifting member 501 has moved to the lifting member predetermined position (see Figure 35 ).

[0176] Furthermore, in some embodiments of the present disclosure, the electric suction lock device 1000 further includes: a first pawl switch 7031. When the lock tongue 101 moves to the secondary closed position, the pawl 201 rotates under the push of the lock tongue 101 and triggers the first pawl switch 7031 (refer to Figure 36 , the pawl 201 releases the pawl first switch 7031) to generate a signal indicating that the lock tongue 101 has moved to the secondary closed position.

[0177] The electric suction lock device of this embodiment is configured with a first pawl switch 7031 to indicate that the lock tongue 101 moves to the secondary closed position (i.e., the half-locked position), eliminating the lock tongue assembly signal device 703 described above. The first pawl switch 7031 can accurately indicate that the lock tongue 101 moves to the secondary closed position.

[0178] In some embodiments of the present disclosure, based on the signal generated by the first pawl switch 7031 indicating that the lock tongue 101 has moved to the secondary closed position, the lifting member 501 is continuously driven from the predetermined position of the lifting member to drive the suction member 502 to drive the lock tongue 101, so that the lock tongue 101 moves from the secondary closed position to the main closed position (fully locked position) (refer to Figure 37 ).

[0179] Furthermore, in some embodiments of the present disclosure, the electric suction lock device 1000 further includes: a second pawl switch 7032. When the lock tongue 101 moves to the main closed position, the pawl 201 rotates under the push of the lock tongue 101 and triggers the second pawl switch 7032 (refer to Figure 37 , the ratchet 201 releases the ratchet second switch 7032) so that it generates the signal indicating that the deadbolt 101 has moved to the main closed position. So far, the electric suction is completed and the locking process is completed.

[0180] In some embodiments of the present disclosure, the pawl 201 operates the first pawl switch 7031 based on the first pawl edge portion 2014 to trigger it, and the pawl 201 operates the second pawl switch 7032 based on the second pawl edge portion 2012 (that is, the second pawl feature 2012 described above) to trigger it.

[0181] In some embodiments of the present disclosure, the operation of the first edge portion 2014 of the pawl on the first switch 7031 is a releasing operation, and the operation of the second edge portion 2012 of the pawl on the second switch 7032 is a releasing operation, and the release path of the second edge portion 2012 of the pawl on the second switch 7032 is greater than the release path of the first edge portion 2014 of the pawl on the first switch 7031.

[0182] In some embodiments of the present disclosure, the pawl first edge portion 2014 and the pawl second edge portion 2012 are disposed opposite to each other on both sides of the pawl 201 .

[0183] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure further includes: a suction actuator 900 having a drive wire 901, and the lifting member 501 is driven to move to a predetermined position of the lifting member based on the drive wire 901 of the suction actuator 900.

[0184] refer to Figure 41 and Figure 42, shows an embodiment of an attraction actuator 900 of the present disclosure. The attraction actuator 900 may also include a drive motor, a worm, a primary gear, a secondary gear, or a tertiary gear, etc. The driving force of the drive motor is transmitted in sequence through the worm, the primary gear, and the secondary gear, and the final gear (which may be a secondary gear or a tertiary gear) drives the drive wire 901, so that the drive wire 901 drives the lifting member 501.

[0185] In some embodiments of the present disclosure, the drive motor, worm, primary gear, secondary gear, etc. of the suction actuator 900 are all arranged inside the suction actuator housing. The suction actuator housing can be composed of upper and lower shells, and the upper and lower shells can be sealed by seals.

[0186] In some embodiments of the present disclosure, the drive wire 901 is drivingly connected to the final gear. The drive wire 901 and the final gear may be separate structures or integrated structures.

[0187] In some embodiments of the present disclosure, the interior of the suction actuator 900 is provided with a drive wire position indication switch (e.g., a neutral switch). The drive wire position indication switch can be triggered by the trigger structure of the final gear, indicating that the drive wire 901 has moved to the drive limit position, and the drive motor no longer outputs driving force to the drive wire 901. Based on the signal of the drive wire position indication switch, the drive motor can output driving force in the reverse direction to reset the drive wire 901.

[0188] In light of the technical solution disclosed herein, those skilled in the art may adjust the specific structure of the suction actuator 900 , all of which fall within the protection scope of the present disclosure.

[0189] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure further includes: a release component 400, which can operate the pawl 201 based on the driving force of the release actuator to disengage the pawl 201 from the lock tongue 101.

[0190] In some embodiments of the present disclosure, the release actuator and the engagement actuator are the same actuator.

[0191] In some embodiments of the present disclosure, the suction actuator 900 also drives a release wire (not shown), one end of the release wire is drive-connected to the final gear described above, and the other end of the release wire is connected to the release assembly 400 (for example, the electric release rod 401) to drive the release assembly.

[0192] In some embodiments of the present disclosure, the interior of the suction actuator 900 is provided with a release wire position indication switch, which can be triggered by another trigger structure of the final gear, indicating that the release wire has moved to the release limit position, and the drive motor no longer outputs driving force to the release wire. Based on the signal of the release wire position indication switch, the drive motor can output driving force in the reverse direction to reset the release wire.

[0193] In some other embodiments of the present disclosure, the release actuator and the pull-in actuator are different actuators. Please refer to the above description of the first electric actuator and the second electric actuator.

[0194] In some embodiments of the present disclosure, the lifting member 501 and the suction member 502 are rotatably connected through an axis (such as a rivet). When the lock tongue 101 is in the secondary closed position and the lifting member 501 is in the lifting member predetermined position ( Figure 36 The state shown), the suction member 502 is engaged with the lock tongue 101, and when the lifting member 501 is continued to be driven by the driving wire 901, the lifting member 501 drives the suction member 502 to drive the lock tongue 101, so that the lock tongue 101 moves to the main closed position (reference Figure 37 ).

[0195] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure further includes: a suction element spring 504, which can load elastic force to the suction element 502 so that the suction element 502 has a tendency to move in the direction of engagement with the lock tongue 101.

[0196] In some embodiments of the present disclosure, the electric suction lock device 1000 of the present disclosure also includes: a lifting member spring 503, which can load elastic force to the lifting member 501, so that the lifting member 501 can drive the lock to lift the lock tongue 101 through the lock, so that the lock tongue 101 moves from the main closed position to the open position.

[0197] In some embodiments of the present disclosure, when the lock tongue 101 is driven to move from the open position to the secondary closed position, before the lock tongue 101 reaches the secondary closed position, the lifting surface 5011 of the lifting member 501 is higher than the lower edge of the fish mouth of the lock tongue 101 (i.e., the second edge 1017 of the fish mouth of the lock tongue, Figure 33 The first edge 1016 of the lock tongue fish mouth and the second edge 1017 of the lock tongue fish mouth are shown, so that when the lock tongue 101 is driven to move from the open position to the secondary closed position, the lock buckle first contacts the lifting surface 5011 of the lifting member 501, and then contacts the lower edge of the fish mouth of the lock tongue 101 to drive the lock tongue 101 to the secondary closed position.

[0198] Through the above-mentioned structural design, during the unlocking process, the lifting member 501 can push the lock catch based on the action of the lifting member spring 503, operating the electric suction lock device 1000 from a semi-locked state (lock tongue in the secondary closed position) to an open state (lock tongue in the open position). This structural design eliminates the need for a snow load mechanism (such as the snow load unit described in Chinese Patent CN202010423903.6) required for existing lock devices.

[0199] In some embodiments of the present disclosure, the status signals of the lock tongue 101 being in the primary closed position and the secondary closed position are both generated by the pawl 201 triggering the corresponding switches (the first pawl switch 7031 and the second pawl switch 7032 ).

[0200] In some embodiments of the present disclosure, the lifting member 501 has a lifting member switch triggering structure 5016 , and the lifting member 501 triggers the lifting member position switch 505 based on the lifting member switch triggering structure 5016 .

[0201] In some embodiments of the present disclosure, the lift switch trigger structure 5016 is a protruding structure so that the signal state of the lift position switch 505 is the same when the lock tongue 101 is in the open position and when the lock tongue 101 is in the main closed position.

[0202] refer to Figure 34 Etc., the present disclosure preferably designs the lifting member switch trigger structure 5016 as a protruding structure, that is, it protrudes in the direction outward from the rotation center of the lifting member 501, so that in the locking process of the electric suction lock device 1000, before the lifting member 501 is operated (at this time the lock tongue is in the open position), the status signal of the lifting member position switch 505 is the first status signal, and when the lifting member 501 is operated to the predetermined position of the lifting member, the status signal of the lifting member position switch 505 is first flipped to the second status signal and then flipped to the first status signal. When the lifting member 501 is in the predetermined position of the lifting member, the status signal of the lifting member position switch 505 is the first status signal, and the lifting member 501 continues to be operated. When the lock tongue 101 moves to the main closed position, the status signal of the lifting member position switch 505 is still the first status signal.

[0203] In some embodiments of the present disclosure, the contact surface of the lifting member switch trigger structure 5016 with the lifting member position switch 505 is covered with a flexible material (such as a plastic material), and the lifting surface 5011 is covered with a flexible material (such as a plastic material).

[0204] Figure 39 Also shown is an emergency release cable 405 via which the mechanical tripping lever 401 can be operated. Figure 39Also shown is a wiring harness plug assembly 902, through which the status signals of the various switches described above can be transmitted to the pull-in actuator / release actuator or the control circuit board described above, which can be configured in the pull-in actuator / release actuator.

[0205] The electric suction lock device 1000 described above in the present disclosure has only one pawl 201 .

[0206] In some embodiments of the present disclosure, the engagement radius of the lock tongue 101 when in the primary closed position is smaller than the engagement radius of the lock tongue 101 when in the secondary closed position. The engagement radius is the distance from the rotation center of the lock tongue to the first locking position / second locking position.

[0207] The present disclosure also provides a motor vehicle lock, comprising: an electric suction lock device 1000 according to any embodiment of the present disclosure; and a lock buckle, which cooperates with a lock tongue 101 to achieve a locking function.

[0208] The present disclosure also provides a motor vehicle, comprising: the motor vehicle lock of the present disclosure.
