[0062] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0063] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0064] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0065] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0066] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0114] refer to Figure 10The lifting member 501 of this disclosure is a component capable of rotating about an axis ("+" position). The lifting member 501 of this disclosure is provided with a lifting surface 5011, which directly engages with the latch. When the latch bolt 101 is released, the lifting member 501 can push the latch from the main locking position to the open position via the lifting surface 5011. Preferably, the lifting engagement assembly 500 and the latch assembly 100 of this disclosure are independent components.

[0115] Continue to refer to Figure 10 The lifting member 501 disclosed herein is also provided with a first hole 5012, a hook-shaped feature 5013, a flanged feature 5014, and a second hole 5015.

[0116] The first hole 5012 of the lifting member is used to connect an electric actuator (e.g., a cable connecting the electric actuator), thereby enabling it to receive force and movement from the electric actuator. The hook-shaped feature 5013 of the lifting member is used to hook the lifting member spring 503 to provide sufficient lifting force. The flanged feature 5014 of the lifting member is used to mate with the housing assembly 700 to limit the movement of the lifting member 501. The second hole 5015 of the lifting member is used to install the suction member 502.

[0117] refer to Figure 11 The present disclosure describes the structure of the suction member 502, which can actuate the locking tongue 101 to move from the secondary closed position to the main closed position. Preferably, the suction member 502 is rotatably disposed on the lifting member 501 via the second hole 5015 of the lifting member.

[0118] Continue to refer to Figure 11 The suction member 502 disclosed herein is provided with a first suction member feature 5021 and a second suction member feature 5022.

[0119] The first feature 5021 of the suction member is used to engage with the third feature 1013 of the locking tongue, so that the suction member 502 can drive the locking 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.

[0120] Preferably, the first feature 5021 of the attracting member is configured such that, during the attracting process, when the latch 101 is prevented from moving toward the main closed position to a position where it can engage with the first feature 5021 of the attracting member by an obstacle, the first feature 5021 of the attracting member cannot engage with the third feature 1013 of the latch; when the latch 101 can move toward the main closed position to a position where it can engage with the first feature 5021 of the attracting member, the first feature 5021 of the attracting member can engage with the third feature 1013 of the latch, and actuates the latch 101 to move from the secondary closed position toward the main closed position.

[0121] The second feature 5022 of the suction member 502 disclosed herein is used to cooperate with the housing assembly 700, thereby controlling the engagement and disengagement of the first feature 5021 of the suction member and the third feature 1013 of the locking tongue. Simultaneously, 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 out of engagement with the third feature 1013 of the locking tongue via the second feature 4022.

[0122] refer to Figure 9 Both the lifting spring 503 and the engaging spring 504 of this disclosure have a preload, which allows the lifting 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 latch from the main locking position to the open position. The engaging spring 504 can apply an elastic force to the engaging member 502, causing the first feature 5021 of the engaging member to tend to move in the direction of engaging with the third feature 1013 of the latch.

[0123] Figure 9 The installation method of the lifting spring 503 and the attracting spring 504 is illustrated by way of example. Under the guidance of the technical solution of this disclosure, those skilled in the art can make adjustments to the installation method of the lifting spring 503 and the attracting spring 504, the specific type of the lifting spring 503 and the attracting spring 504, etc., all of which fall within the protection scope of this disclosure.

[0124] Figures 12 to 14 This is a schematic diagram of the clutch assembly 600 of an electric magnetic locking device 1000 according to one embodiment of the present disclosure.

[0125] refer to Figures 12 to 14 The clutch assembly 600 of the electric magnetic locking device 1000 disclosed herein includes a clutch actuator 601, a clutch drive 602, a clutch return spring 603, and a clutch drive spring 604.

[0126] The clutch assembly 600 disclosed herein is movable between an operating position and a non-operating position. When the clutch assembly 600 is in the operating position, the movement of the release assembly 400 to the actuated position can only drive the pawl 201 to the secondary locking position; when the clutch assembly 600 is in the non-operating position, the movement of the release assembly 400 to the actuated position can drive the pawl 201 to the unlocked position.

[0127] Continue to refer to Figures 12 to 14 The clutch drive 602 and clutch actuator 601 of the clutch assembly 600 of the electric magnetic locking device 1000 disclosed herein are configured such that:

[0128] When the locking tongue 101 leaves the main closed position, the clutch drive 602 can drive the clutch actuator 601 to leave the operating position and enter the non-operating position.

[0129] When the locking tongue 101 enters the main closed position, the locking 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 mounted on the base plate 300 ("+" indicates the position of the rotation axis).

[0130] refer to Figure 12 and Figure 13 The clutch actuator 601 disclosed herein is provided with a clutch actuator hook-shaped portion 6011 (first end) and a clutch actuator protruding feature 6012 (second end).

[0131] The clutch actuator hook-shaped portion 6011 engages with the second feature 4012 of the electric release lever. When the clutch actuator 601 is in the operating position, the clutch actuator hook-shaped portion 6011 and the second feature 4012 of the electric release lever are engaged, restricting the release assembly 400 to only actuate the pawl 201 to the secondary locking position. When the clutch actuator 601 is in the non-operating position, the clutch actuator hook-shaped portion 6011 disengages from the engagement with the second feature 4012 of the electric release lever, releasing the restriction on the release assembly 400, allowing the release assembly 400 to actuate the pawl 201 to the unlocked position. Preferably, the clutch actuator hook-shaped portion 6011 only releases the clutch actuator 601, returning it to the non-operating position, after the second feature 4012 of the electric release lever has disengaged from the hook groove of the clutch actuator hook-shaped portion 6011.

[0132] The clutch actuator protrusion 6012 is used to cooperate with the clutch drive 602 so that the clutch drive 602 drives the clutch actuator 601 to leave or enter the operating position.

[0133] refer to Figure 14 The clutch drive component 602 disclosed herein is provided with a first clutch drive component feature 6021, a second clutch drive component feature 6022 and a third clutch drive component feature 6023.

[0134] The clutch drive component first feature 6021 is used to cooperate with the lock tongue fourth feature 1014. When the lock tongue 101 enters the main closed position, the lock tongue 101 drives the clutch drive component 602 through the lock tongue fourth feature 1014, thereby actuating the clutch actuator 601 to enter the operating position.

[0135] When the latch 101 leaves the main closed position, the clutch actuator 601, under the action of the clutch drive spring 604, leaves the operating position, thereby disengaging the clutch actuator hook-shaped portion 6011 from the electric release lever 401. The second feature 6022 of the clutch drive member is used to engage the clutch drive spring 604. The third feature 6023 of the clutch drive member is used to cooperate with the clutch actuator protruding feature 6012, thereby driving the clutch actuator 601 to leave or enter the operating position.

[0136] refer to Figure 12 The clutch return spring 603 and clutch drive spring 604 of this disclosure have preload, which allows the clutch return spring 603 to apply an elastic force to the clutch actuator 601, enabling the clutch actuator 601 to move together with the clutch drive member 602 ("+" indicates the position of the rotation axis). The clutch drive spring 604 can apply an elastic force to the clutch drive member 602, enabling the clutch drive member 602 to actuate the clutch actuator 601 to leave the operating position.

[0137] Figure 12 The installation method of clutch return spring 603 and clutch drive spring 604 is illustrated by way of example. Those skilled in the art can make adjustments to the installation method, specific type, etc. of clutch return spring 603 and clutch drive spring 604 under the guidance of the technical solution of this disclosure, and all such adjustments will fall within the protection scope of this disclosure.

[0138] Figure 15 This is a schematic diagram of the housing assembly 700 of an electric suction lock device 1000 according to one embodiment of the present disclosure.

[0139] refer to Figure 15 The housing assembly 700 of the electric magnetic locking device 1000 disclosed herein includes a housing 701, a latch assembly signal device 702, and a pawl assembly signal device 703.

[0140] Continue to refer to Figure 15 The housing 701 disclosed herein is provided with a first housing feature 7011, a second housing feature 7012, a housing connector 7013 and a housing buffer block 7014.

[0141] The first feature 7011 of the housing is used to cooperate with the second feature 5022 of the suction member, so that the first feature 5021 of the suction member can engage or disengage with the third feature 1013 of the locking tongue, thereby enabling the lifting suction assembly 500 to disengage or engage with the locking tongue 101.

[0142] The second feature 7012 of the housing is used to cooperate with the flanged feature 5014 of the lifting member to limit the lifting member 501. The housing connector 7013 is used to connect to the vehicle wiring harness to transmit the status signals of the latch assembly signal device 702 and the pawl assembly signal device 703 to the vehicle controller.

[0143] Continue to refer to Figure 15 In the present disclosure, the signal state of the latch assembly signal device 702 changes as the latch 101 moves from the open position to the main closed position, when the latch 101 approaches or enters the secondary closed position. Similarly, in the present disclosure, the signal state of the pawl assembly signal device 703 changes when the pawl 201 changes from an unengaged state to an engaged state in the first locking position of the latch 101, instructing the pawl 201 to hold the latch 101 in the main locking position.

[0144] Preferably, the pawl assembly signal device 703 and the latch assembly signal device 702 of this disclosure are both mounted on the housing 701. The housing 701 preferably fixes the required wiring harness by injection molding and is connected to the vehicle wiring harness through the housing connector 7013, so as to transmit the status signal of the latch assembly signal device 702 and the status signal of the pawl assembly signal device 703 to the vehicle controller.

[0145] Continue to refer to Figure 15 The housing buffer block 7014 disclosed herein can provide cushioning for the latch when the latch is locked into the main closed position.

[0146] Figure 16 This is a schematic diagram of the cover plate 800 of an electric suction lock device 1000 according to one embodiment of the present disclosure.

[0147] refer to Figure 16 The cover plate 800 of the electric suction lock device 1000 disclosed herein is provided with a first feature 8001 and a second feature 8002.

[0148] The cover plate has a first feature 8001 that is snapped into the housing 701 to increase the strength of the housing 701. The cover plate has a second feature 8002 that provides a snap-fit ​​structure for the cable of the lifting and engaging assembly 500, so as to transmit the power and motion of the electric actuator to the lifting and engaging assembly 500.

[0149] In some embodiments of this disclosure, the electric magnetic locking device 1000 further includes a first electric actuator. 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 locking tongue 101, thereby realizing the electric unlocking of the electric magnetic locking device 1000.

[0150] In some embodiments of this disclosure, the electric engaging lock device 1000 further includes a second electric actuator. The driving force of the second electric actuator can be transmitted to the lifting member 501. The lifting member 501 drives the engaging member 502 to move. When the locking tongue 101 can move in the direction of the main closing position, the engaging member 502 can engage with the locking tongue 101, thereby realizing the electric engaging of the locking device.

[0151] In some embodiments of this disclosure, the first electric actuator and the second electric actuator may be the same actuator.

[0152] The electric release lever 401 of this disclosure can be connected to the first electric actuator described above via a Bowden cable. The engaging member 502 can 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 engaging member 502 are arranged on the same side of the locking device.

[0153] The first electric actuator and the second electric actuator may adopt the electric actuators in Chinese patents CN202010283886.0, CN202020530719.7, and CN202111476814.9 or other similar structures, which will not be described in detail in this disclosure.

[0154] In other embodiments of this disclosure, the first electric actuator, the second electric actuator, and the electric engaging lock device 1000 can be integrated into a single unit, thereby reducing costs.

[0155] Figures 17 to 24 This is a schematic diagram of the electric release process of an electric magnetic locking device 1000 according to one embodiment of the present disclosure.

[0156] refer to Figure 17 and Figure 18 In the electrically operated magnetic locking device 1000 of this disclosure, the bolt 101 is in the main closed position, and the pawl 201 is in the main locked position. Both the bolt assembly signal device 702 and the pawl assembly signal device 703 are in an untriggered state. The electrically operated release lever 401 is not in the actuated position.

[0157] refer to Figure 19When the release assembly 400 is first operated to the actuated position, the electric release lever 401 pushes the pawl 201 away from the primary locking position. Due to the constraint of the clutch actuator hook portion 6011, 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 engaging member 502 to move, and the engaging member 502 drives the locking tongue 101. The locking tongue 101 will move towards the secondary closed position, thereby pushing the latch towards the opening direction. Since the pawl 201 is in the secondary locking position, the locking 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 magnetic locking device 1000 has been unlocked.

[0158] refer to Figure 21 When the electric release lever 401 is released, under the action of the release component spring 403, the electric release lever 401 will return to its initial position (i.e., the non-actuated position). Since the locking tongue 101 has left the main closed position at this time, the locking tongue 101 (locking tongue fourth feature 1014) releases the constraint on the clutch drive member 602 (clutch drive member first feature 6021). 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 drive 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, because the clutch actuator hook portion 6011 has released the constraint on the electric release lever 401, the electric release lever 401 can push the pawl 201 from the secondary locked position to the unlocked position, allowing the latch 101 to move from the secondary closed position to the open position, such as... Figure 22 As shown.

[0159] like Figure 22 and Figure 23 As shown, when the pawl 201 is pushed to the unlocked position, the bolt 101 can move from the partially closed position to the open position. At this time, under the action of the lifting member 501, the bolt 101 will move towards the open position, thereby pushing the latch to move in the open direction. When the lifting member flange feature 5014 contacts the housing second feature 7012, the lifting member 501 is limited and no longer pushes the latch to move in the open direction. At this time, the bolt assembly signal device 702 is still not triggered, indicating that the bolt 101 is not in the fully open position.

[0160] like Figure 24 As shown, when the latch is pushed by an external force, causing the bolt 101 to reach the fully open position, the bolt assembly signal device 702 is triggered, indicating that the bolt 101 has reached the fully open position. At this time, the electric magnetic locking device 1000 is in the fully open state.

[0161] Figures 25 to 30 This is a schematic diagram of the electric engagement process of an electric engagement lock device 1000 according to one embodiment of the present disclosure.

[0162] refer to Figure 25 When the latch moves downward, it will push the latch tongue 101 from the open position to the secondary closed position. When the latch and the lifting member 501 come into contact, the latch 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 towards the main closed position.

[0163] like Figure 26 As shown, the suction member 502 moves together with the lifting member 501. When the suction member 502 moves to the point where the second feature 5022 of the suction member is freed from the constraint of the first feature 7011 of the housing, the suction member 502 will move in the direction of the third feature 1013 of the locking tongue under the action of the suction member spring 504.

[0164] like Figure 27 As shown, when the latch 101 is blocked by an obstacle (e.g., a hand) and cannot fall under the action of gravity, the first feature 5021 of the engaging member cannot lock into the third feature 1013 of the latch, thereby preventing the lifting member 501 from pushing the latch 101 toward the main closing position, thus achieving obstacle anti-pinch.

[0165] like Figure 28 As shown, when the latch 101 falls under the action of gravity, the first feature 5021 of the engaging member can lock into the third feature 1013 of the latch, so that the lifting member 501 can push the latch 101 to move towards the main closing position, thereby realizing electric engagement.

[0166] like Figure 29 and Figure 30 As shown, as the latch 101 is pushed to the main closed position, the pawl 201 can enter the main locking position, and the pawl assembly signal device 703 is released, thereby completely locking the electric magnetic locking device 1000. At the same time, the fourth feature 1014 of the latch actuates the first feature 6021 of the clutch drive member, causing the clutch drive member 602 to drive the clutch actuator 601 into the operating position, so that the hook-shaped portion 6011 of the clutch actuator can again restrain the stroke of the electric release lever 401.

[0167] Figures 31 to 33 This is a schematic diagram of the mechanical unlocking process of an electrically operated magnetic locking device 1000 according to one embodiment of this disclosure.

[0168] refer to Figures 31 to 33When the mechanical release lever 402 moves under the operation direction 1 or operation direction 2, it pushes the electric release lever 401 to move together. After undergoing the same action as the aforementioned electric unlocking, the electric magnetic locking device 1000 can be mechanically unlocked. Simultaneously, the second feature 4022 of the mechanical release lever pushes the second feature 5022 of the magnetic member, causing the first feature 5021 of the magnetic member to disengage from the latch 101. This achieves disengagement between the magnetic member 502 and the latch 101, ensuring that even in special circumstances such as a power outage during the magnetic locking process, the electric magnetic locking device 1000 can still be mechanically released via the mechanical release lever 402. Figure 32 and Figure 33 As shown.

[0169] refer to Figures 34 to 42 Based on the electric magnetic locking device described above, this disclosure also provides the following electric magnetic locking device with the following technical solutions, through technical adjustments. It should be noted that the lock tongue assembly 100 and its sub-components, pawl assembly 200 and its sub-components, release assembly 400 and its sub-components, lifting magnetic engagement assembly 500 and its sub-components, clutch assembly 600 and its sub-components, and other structures not described in detail below, can also be used in the electric magnetic locking device described below. The following focuses on describing the content involved in the technical solution adjustments.

[0170] refer to Figures 1 to 42 Especially Figures 34 to 42 In some embodiments of this disclosure, the electrically operated magnetic locking device 1000 includes:

[0171] The latch 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 latch 101 can move between a main closed position, a secondary closed position and an open position.

[0172] Pawl 201 is movable between a main locking position, a secondary locking position, and an unlocking position. In the main locking position, pawl 201 engages with the first locking position 1011 of the latch 101, locking the latch 101 in the main closed position. In the secondary locking position, pawl 201 engages with the second locking position 1012 of the latch 101, locking the latch 101 in the secondary closed position.

[0173] The base plate 300, the locking tongue 101 and the pawl 201 are all rotatably mounted on the base plate 300;

[0174] When the latch 101 is released by the pawl 201, the lifting member 501 (also known as the lifting rod) pushes the latch 101 from the main closed position to the open position via the latch.

[0175] The suction element 502 can actuate the locking tongue 101 to move from the secondary closed position to the main closed position.

[0176] During the locking process, the lifting member 501 is driven before the locking tongue 101, and the lifting member 501 is driven to the predetermined position of the lifting member ( Figure 35 The latch 101 is driven to move to the secondary closed position, and the engaging member 502 drives the latch 101 to the main closed position.

[0177] The technical solution of this embodiment, by configuring the lifting member 501 to be driven to a predetermined position before the locking tongue 101, can reduce the driving force required to drive the locking tongue 101 to the secondary closed position (i.e., the position waiting to engage), thereby increasing the reliability of the electric engaging lock device 1000. The locking tongue 101 can be driven by the latch to move from the open position to the secondary closed position.

[0178] In some embodiments of this disclosure, when the control circuit board of the electric magnetic locking device 1000 receives a locking signal (the locking signal may come from a remote key or be generated by a trigger button on the car hood), the latch is driven by the driving force (i.e., external force) from the motor to drive the bolt 101, causing the bolt 101 to move from the open position to the closed position. Figure 36 (The state shown is the motion.)

[0179] In other embodiments of this disclosure, the external force that drives the latch described above can be a mechanical operating force, such as a pressing operating force on the hood of a car (front hatch), which drives the latch, thereby driving the latch tongue 101 and causing the latch tongue to move to the secondary closed position.

[0180] Furthermore, in some embodiments of this disclosure, the electric magnetic locking device 1000 further includes: a lifting member position switch 505, which triggers the lifting member position switch 505 to generate a signal indicating that the lifting member 501 has moved to the predetermined lifting member position when the lifting member 501 is driven to the predetermined lifting member position (see reference). Figure 35 ).

[0181] Furthermore, in some embodiments of this disclosure, the electrically operated magnetic locking device 1000 further includes a pawl first switch 7031, which, when the bolt 101 moves to the sub-closed position, causes the pawl 201 to rotate under the push of the bolt 101 and triggers the pawl first switch 7031 (see reference). Figure 36 The pawl 201 releases the first pawl switch 7031 to generate a signal indicating that the latch 101 has moved to the second closed position.

[0182] The electric latching lock device of this embodiment uses a pawl first switch 7031 to indicate that the latch 101 moves to the secondary closed position (i.e., the half-locked position), thus eliminating the need for the latch assembly signal device 703 described above. The pawl first switch 7031 can accurately indicate that the latch 101 moves to the secondary closed position.

[0183] In some embodiments of this disclosure, based on the signal generated by the pawl first switch 7031 indicating that the latch 101 has moved to the secondary closed position, the lifting member 501 is further driven from a predetermined position to drive the engaging member 502 to drive the latch 101, causing the latch 101 to move from the secondary closed position to the primary closed position (fully locked position) (see reference). Figure 37 ).

[0184] Furthermore, in some embodiments of this disclosure, the electrically operated magnetic locking device 1000 further includes a pawl second switch 7032, which, when the bolt 101 moves to the main closed position, causes the pawl 201 to rotate under the push of the bolt 101 and triggers the pawl second switch 7032 (see reference). Figure 37 The pawl 201 releases the second pawl switch 7032, causing it to generate a signal indicating that the bolt 101 has moved to the main closed position. This completes the electric engagement and locking process.

[0185] In some embodiments of this disclosure, the pawl 201 operates the pawl first switch 7031 based on the pawl first edge portion 2014 to trigger it, and the pawl 201 operates the pawl second switch 7032 based on the pawl second edge portion 2012 (i.e., the pawl second feature 2012 described above) to trigger it.

[0186] In some embodiments of this disclosure, the operation of the first edge portion 2014 of the pawl to the first switch 7031 is a release operation, the operation of the second edge portion 2012 of the pawl to the second switch 7032 is a release operation, and the release path of the second edge portion 2012 of the pawl to the second switch 7032 is greater than the release path of the first edge portion 2014 of the pawl to the first switch 7031.

[0187] In some embodiments of this disclosure, the first edge portion 2014 and the second edge portion 2012 of the pawl are disposed opposite to each other on both sides of the pawl 201.

[0188] In some embodiments of this disclosure, the electric magnetic locking device 1000 further includes: a magnetic actuator 900 having a drive cable 901, wherein a lifting member 501 is driven to move to a predetermined position based on the drive cable 901 of the magnetic actuator 900.

[0189] refer to Figure 41 and Figure 42The illustration shows a suction actuator 900 according to one embodiment of the present disclosure. The suction actuator 900 may also include a drive motor, a worm gear, a first-stage gear, a second-stage gear, or a third-stage gear. The driving force of the drive motor is transmitted sequentially through the worm gear, the first-stage gear, and the second-stage gear. The final stage gear (which may be a second-stage gear or a third-stage gear) drives the drive cable 901, thereby causing the drive cable 901 to drive the lifting member 501.

[0190] In some embodiments of this disclosure, the drive motor, worm gear, primary gear, secondary gear, etc. of the suction actuator 900 are all disposed inside the suction actuator housing. The suction actuator housing may be composed of upper and lower housings, which may be sealed by a sealing element.

[0191] In some embodiments of this disclosure, the drive cable 901 is driven and connected to the final stage gear. The drive cable 901 and the final stage gear can be separate structures or integrated structures.

[0192] In some embodiments of this disclosure, the actuator 900 is internally configured with a drive cable position indicator switch (e.g., a neutral switch). The drive cable position indicator switch can be triggered by the triggering structure of the final gear to indicate that the drive cable 901 has moved to the drive limit position, and the drive motor no longer outputs driving force to the drive cable 901. Based on the signal of the drive cable position indicator switch, the drive motor can output driving force in the opposite direction to reset the drive cable 901.

[0193] Those skilled in the art, inspired by the technical solutions disclosed herein, can adjust the specific structure of the suction actuator 900, all of which fall within the protection scope of this disclosure.

[0194] In some embodiments of this disclosure, the electric engaging lock device 1000 further includes a release component 400, which is capable of operating the pawl 201 based on the driving force of the release actuator, so that the pawl 201 disengages from the locking tongue 101.

[0195] In some embodiments of this disclosure, the release actuator and the engagement actuator are the same actuator.

[0196] In some embodiments of this disclosure, the pull actuator 900 also drives a release cable (not shown), one end of which is connected to the final stage gear drive described above, and the other end of which is connected to the release assembly 400 (e.g., electric release lever 401) to drive the release assembly.

[0197] In some embodiments of this disclosure, the actuator 900 is internally equipped with a release cable position indicator switch. The release cable position indicator switch can be triggered by another triggering structure of the final gear to indicate that the release cable has moved to the release limit position, and the drive motor no longer outputs driving force to the release cable. Based on the signal of the release cable position indicator switch, the drive motor can output driving force in the opposite direction to reset the release cable.

[0198] In other embodiments of this disclosure, the release actuator and the engagement actuator are different actuators. See the preceding descriptions of the first electric actuator and the second electric actuator.

[0199] In some embodiments of this disclosure, the lifting member 501 and the engaging member 502 are rotatably connected by a shaft (e.g., a rivet), when the latch 101 is in the sub-closed position and the lifting member 501 is in the predetermined lifting position ( Figure 36 In the state shown, the engaging member 502 engages with the latch 101. When the lifting member 501 continues to be driven by the drive cable 901, the lifting member 501 drives the engaging member 502 to drive the latch 101, causing the latch 101 to move towards the main closed position (see reference). Figure 37 ).

[0200] In some embodiments of this disclosure, the electric magnetic locking device 1000 further includes a magnetic spring 504, which can apply an elastic force to the magnetic member 502, causing the magnetic member 502 to tend to move in the direction of engaging with the latch 101.

[0201] In some embodiments of this disclosure, the electric latching device 1000 further includes a lifting spring 503, which can apply an elastic force to the lifting member 501, so that the lifting member 501 can drive the latch to lift the latch tongue 101 via the latch, so that the latch tongue 101 moves from the main closed position to the open position.

[0202] In some embodiments of this disclosure, during the process of the latch 101 being driven to move from the open position to the secondary closed position, before the latch 101 reaches the secondary closed position, the lifting surface 5011 of the lifting member 501 is higher than the lower edge of the latch 101's mouth (i.e., the second edge 1017 of the latch mouth). Figure 33 The first edge 1016 and the second edge 1017 of the latch mouth are shown, such that during the process of the latch 101 being driven to move from the open position to the secondary closed position, the latch first contacts the lifting surface 5011 of the lifting member 501, and then contacts the lower edge of the latch mouth of the latch 101 to drive the latch 101 to the secondary closed position.

[0203] Through the above-described structural design, during the unlocking process, the lifting member 501 can push the latch based on the action of the lifting member spring 503, operating the electric magnetic locking device 1000 from the semi-locked state (lock tongue in the secondary closed position) to the open state (lock tongue in the open position). This structural design eliminates the need for the snow-load mechanism (such as the snow-load unit in Chinese Patent CN202010423903.6) required by existing locking devices.

[0204] In some embodiments of this disclosure, the status signals of the latch 101 in the main closed position and the secondary closed position are generated by the pawl 201 triggering the corresponding switches (pawl first switch 7031, pawl second switch 7032).

[0205] In some embodiments of this disclosure, the lifting member 501 has a lifting member switch triggering structure 5016, which triggers the lifting member position switch 505.

[0206] In some embodiments of this disclosure, the lifting switch triggering structure 5016 is a protruding structure, such that the signal state of the lifting position switch 505 is the same when the latch 101 is in the open position and when the latch 101 is in the main closed position.

[0207] refer to Figure 34 In this disclosure, the lifting member switch trigger structure 5016 is preferably designed as a protruding structure, that is, it protrudes outward from the rotation center of the lifting member 501. This allows the lifting member 501 to be operated before the electric suction lock device 1000 is engaged (at which time the lock tongue is in the open position) during the locking process. The state signal of the lifting member position switch 505 is the first state signal. When the lifting member 501 is operated to the predetermined position, the state signal of the lifting member position switch 505 first flips to the second state signal and then flips back to the first state signal. When the lifting member 501 is in the predetermined position, the state signal of the lifting member position switch 505 is the first state signal. The lifting member 501 continues to be operated. When the lock tongue 101 moves to the main closed position, the state signal of the lifting member position switch 505 is still the first state signal.

[0208] In some embodiments of this disclosure, the contact surface between the lifting member switch trigger structure 5016 and the lifting member position switch 505 is covered with a flexible material (e.g., plastic material), and the lifting surface 5011 is covered with a flexible material (e.g., plastic material).

[0209] Figure 39 An emergency release cable 405 is also shown, via which the mechanical release lever 402 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.

[0210] The electrically operated magnetic locking device 1000 described above in this disclosure has one and only one pawl 201.

[0211] In some embodiments of this disclosure, the engagement radius of the latch 101 when it is in the primary closed position is smaller than the engagement radius of the latch 101 when it is in the secondary closed position. The engagement radius is the distance from the center of rotation of the latch to the first locking position / second locking position.

[0212] refer to Figures 1 to 42 Based on the electric engaging lock device described above, this disclosure also provides a double-pull electric release lock system. It should be noted that the lock tongue assembly 100 and its sub-components, pawl assembly 200 and its sub-components, release assembly 400 and its sub-components, lifting engaging assembly 500 and its sub-components, clutch assembly 600 and its sub-components, and other structures not described in detail below, can also be used in the electric engaging lock device of the double-pull electric release lock system described below. The double-pull electric release lock system of this disclosure is described in detail below.

[0213] In some embodiments of this disclosure, the double-pull electric release lock system of this disclosure includes:

[0214] Two electrically operated magnetic locking devices 1000 are arranged on both sides of the vehicle's center plane (a vertical plane that divides the vehicle into two symmetrical parts in the width direction) to perform a locking function on the vehicle's hood.

[0215] A release actuator 900 has a drive motor and is drivenly connected to two electric magnetic locking devices 1000 respectively, so that the release actuator 900 can synchronously unlock the two electric magnetic locking devices 1000.

[0216] The unlocking operation performed by the release actuator 900 (see the description above, which can also be used as a pull actuator) on the electric pull lock device 1000 includes a first release operation and a second release operation. The first release operation releases the electric pull lock device 1000 from a fully locked state to a half-locked state, and the second release operation releases the electric pull lock device 1000 from a half-locked state to a fully open state.

[0217] At least one electrically operated magnetic locking device 1000 is provided with a lock status indicator switch to indicate whether the electrically operated magnetic locking device 1000 is in a fully locked state, a partially locked state, or a fully open state.

[0218] This disclosure configures the double-pull electric release lock system of this disclosure with one release actuator and two electric suction lock devices. The unlocking operation of the two electric suction lock devices can be realized by one actuator, thus constructing a simplified system structure.

[0219] In the preceding description, the release actuator / engagement actuator can be used as a component of the electric engagement lock device. In this embodiment and the following technical solutions, the release actuator / engagement actuator is not part of the electric engagement lock device. Those skilled in the art, under the guidance of the technical solutions disclosed herein, may classify the release actuator / engagement actuator as part of the electric engagement lock device or as not part of the electric engagement lock device, and all such classifications fall within the protection scope of this disclosure.

[0220] In some embodiments of this disclosure, the release actuator 900 of the double-pull electric release lock system of this disclosure is driven connected to two electric engaging lock devices 1000 respectively via pull wires (such as Boden pull wires). Figure 41 and Figure 42 The drive cable shown can be used as a release cable.

[0221] In some embodiments of this disclosure, each electrically engaged locking device 1000 of the double-pull electrically released lock system of this disclosure includes: a latch 101 having a first locking position 1011 and a second locking position 1012, wherein the latch 101 is movable between a main closed position, a secondary closed position, and an open position based on the first locking position 1011 and the second locking position 1012; and a pawl 201 movable between a main locking position, a secondary locking position, and an unlocking position; in the main locking position, the pawl 201 engages with the first locking position 1011 of the latch 101 to lock the latch 101 in the main closed position; in the secondary locking position, the pawl 201 engages with the second locking position 1012 of the latch 101 to lock the latch 101 in the secondary closed position.

[0222] Specifically, when the latch 101 is in the open position, the electric magnetic locking device 1000 is in the fully open state; when the latch 101 is in the secondary closed position, the electric magnetic locking device 1000 is in the semi-locked state; and when the latch 101 is locked in the main closed position by the pawl 201, the electric magnetic locking device 1000 is in the fully locked state.

[0223] In some embodiments of this disclosure, the release actuator 900 of the double-pull electric release lock system outputs a release action based on a main pull line, and the main pull line is driven connected to two electric suction lock devices 1000 respectively via two auxiliary pull lines connected to it (which may be fixedly connected).

[0224] In some embodiments of this disclosure, the main pull cable is connected to two auxiliary pull cables via a pull cable converter.

[0225] The draw wire converter disclosed herein can adopt the relevant structure of the Bowden draw wire system described in Chinese patent document CN201810599078.8 or other existing structures.

[0226] In some other embodiments of this disclosure, the release actuator 900 of the double-pull electric release lock system is driven connected to two electric suction lock devices 1000 via two pull cables respectively.

[0227] In some embodiments of this disclosure, the draw wire converter includes: a draw wire converter housing; and a conversion part disposed within the draw wire converter housing, the conversion part performing the conversion action based on rotation about a rotation axis or based on translation.

[0228] The pull-cord converter in this embodiment can adopt the pull-cord distributor disclosed in Chinese Patent Document CN202211179961.4. The housing of the pull-cord converter disclosed herein can be composed of the outer shell body and the cover body disclosed therein. The conversion part of the pull-cord converter disclosed herein can be composed of the first pull-cord unit, the second pull-cord unit, and the connecting unit disclosed therein. Those skilled in the art, inspired by the technical solution of this disclosure, can also use other existing pull-cord converters, all of which fall within the protection scope of this disclosure.

[0229] In some embodiments of this disclosure, the wire converter further includes a conversion unit reset spring, wherein the conversion unit is reset based on the conversion unit reset spring.

[0230] In some embodiments of this disclosure, the cable distributor disclosed in Chinese Patent Document CN202211179961.4 is structurally improved by configuring a conversion part return spring inside the housing. For example, one end of the return spring is fixed to the fixing member of the second cable unit or to the upper / lower end face of the second pulley of the second cable unit, and the other end of the return spring is fixed to the inner wall of the housing near the second pulley and away from the first pulley. Thus, after the release actuator 900 performs the release operation on the two electric suction lock devices, the cable converter can be reset based on the elastic force of the conversion part return spring.

[0231] For the double-pull electric release lock system described above, the electric engaging lock device 1000 includes: a clutch assembly 600, which is movable between an operating position and a non-operating position; when the clutch assembly 600 is in the operating position, the release actuator 900 can perform a first release operation but cannot perform a second release operation; when the clutch assembly 600 is in the non-operating position, the release assembly 400 can perform a second release operation.

[0232] In some embodiments of this disclosure, the electrically operated locking device 1000 further includes an electrically operated release lever 401. The release actuator 900 performs a first release operation and a second release operation by driving the electrically operated release lever 401. During the first release operation, the electrically operated release lever 401 can operate the pawl 201 to disengage it from the primary locking position and move it to the secondary locking position. During the second release operation, the electrically operated release lever 401 can operate the pawl 201 to disengage it from the secondary locking position and move it to the unlocked position.

[0233] Preferably, the clutch assembly 600 of this disclosure limits the travel range of the electric release lever 401, so that the electric release lever 401 can perform a first release operation but cannot perform a second release operation, or enables the electric release lever 401 to perform a second release operation.

[0234] As described above in this disclosure, the lock status indicator switch is an indicator switch that indicates the position of the pawl 201.

[0235] In a preferred embodiment of this disclosure, the electric magnetic locking device 1000 has two lock status indicator switches (preferably the first pawl switch 7031 and the second pawl switch 7032 described above); when the pawl 201 is in the unlocked position, both lock status indicator switches are in the first state; when the pawl 201 is in the secondary locking position, one of the two lock status indicator switches is in the first state and the other is in the second state; when the pawl 201 is in the primary locking position, both lock status indicator switches are in the second state; wherein the first state and the second state are different signal states.

[0236] Referring to the above description of the first pawl switch 7031 and the second pawl switch 7032, the pawl 201 of the electric locking device 1000 of the double-pull electric release lock system of this disclosure operates the two lock status indicator switches based on different locations to change the signal status of the lock status indicator switches.

[0237] Based on the double-pull electric release lock system described above, this disclosure provides a motor vehicle, including a double-pull electric release lock system according to any embodiment of this disclosure, which is used to perform a locking function on the hood of a vehicle.
