Abstract
Description
Technical Field
[0001] The present invention particularly relates to an ignition lock with an idle mode. Background Art
[0002] Currently, the ignition locks on the market are unlocked with a mechanical key or a remote control key. The rotary knob is locked. If the knob is opened violently, it will break or damage the internal electromagnet's magnet pin, shaft and other components.
[0003] For example, the Chinese invention patent document with publication number "CN218447690U" discloses an ignition switch lock capable of both keyless and keyed start. The lock comprises a lock body, a pin, a knob, a lock cylinder linkage assembly, a rotating shaft, a rotor switch, a drive plate, and a lock tongue. The lock cylinder linkage assembly includes a lock cylinder, a lock cylinder sleeve, a blade, and a blade hole structure. The lock cylinder sleeve is connected to the knob at its upper end and the rotating shaft at its lower end. A pin slot is provided on a pin slot positioning block, which is fixedly connected to the lock cylinder. A linkage structure is provided between the lock cylinder and the lock cylinder sleeve. When the lock cylinder moves downward along the lock cylinder sleeve axis, the pin slot positioning block simultaneously moves downward, forcing the pin to exit the pin slot, causing the lock cylinder to rotate circumferentially in conjunction with the lock cylinder sleeve. This solution primarily enables key removal in each gear position.
[0004] From paragraph 0064 to the last paragraph of the disclosure document, it can be seen that the ignition lock can "lock the steering wheel regardless of whether a key is used or not, or whether a remote control is not available," and that "when the vehicle needs to be turned off, the knob can be turned directly from the ignition position to the shutdown position, without inserting a mechanical key or activating the remote control key 11." This information indicates that the knob only rotates in the specific direction or axial direction required for "gear shifting," not in any arbitrary direction. This does not fully address the issue of "fracture or damage to knobs, pins, and other components caused by forceful unlocking or arbitrary twisting."
[0005] Violent unlocking or random twisting usually involves twisting the knob in any direction (such as excessive clockwise / counterclockwise) or beyond the range (such as continuing to twist beyond the LOCK position) in an attempt to destroy the lock through impact. Summary of the Invention
[0006] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide an ignition lock with an idling mode, so that the knob can idle when not unlocked, solving the technical problem in the background technology of "not being able to idle completely due to gear constraints when twisted violently or arbitrarily".
[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an ignition lock with an idle mode, comprising a lock body, a knob rotatably connected to the lock body, a lock core linkage unit linked to the knob, and a rotating shaft, the lock body being provided with a rotor switch at the end of the rotating shaft away from the lock core linkage unit, the lock body being also provided with a driving plate and a lock tongue, the rotating shaft controlling the telescopic movement of the lock tongue through the driving plate, characterized in that a connecting seat is provided between the rotating shaft and the lock core linkage unit, the lower end of the connecting seat is linked to the rotating shaft, a linkage separation mechanism is provided between the connecting seat and the lock core linkage unit, when the ignition lock is in a locked state, the linkage separation mechanism separates the connecting seat from the lock core linkage unit; when the ignition lock is in an unlocked state, the linkage separation mechanism keeps the connecting seat linked to the ignition transmission unit, and the ignition lock can switch gears.
[0008] With the above technical solution, the locked state refers to the state in which the ignition lock has not been unlocked by means of a mechanical key, remote control, or NFC or other electronic control signal (e.g., no key / remote control / NFC operation after the vehicle is turned off). At this time, the linkage separation mechanism disconnects the linkage between the knob and the ignition transmission unit. The unlocked state refers to the state in which the ignition lock has been unlocked by means of mechanical key insertion, remote control, or NFC signal driving an electromagnet (e.g., operation before the vehicle is ignited). At this time, the linkage separation mechanism connects the operating unit to the ignition transmission unit. When the ignition lock is in the locked state, the linkage separation mechanism disconnects the connecting seat from the lock cylinder linkage unit. At this time, the transmission relationship between the knob, lock cylinder linkage assembly, and connecting seat is disconnected. If a violent unlocker attempts to turn the knob in any direction or beyond the range, the knob will idle and will not be able to transmit the power to the connecting seat and its linked shaft, drive plate, lock tongue, and other components, thereby avoiding the possibility of the knob breaking or internal pin shaft, shaft, and other components being damaged due to impact. When the ignition lock is unlocked, the linkage separation mechanism maintains the linkage between the connector, the lock cylinder linkage unit, and the knob. The knob's rotation is transmitted to the shaft through the lock cylinder linkage unit and connector, which normally drives the drive plate to control the extension and retraction of the lock tongue, achieving the gear shifting function. This design not only ensures normal gear operation during use, but also effectively resists damage from violent unlocking or arbitrary twisting through the "idle rotation separation" mechanism.
[0009] The above-mentioned ignition lock with idle mode can be further configured as follows: the lock core linkage unit includes a lock core, the lower end of the lock core is provided with a main mounting hole sleeved on the outer periphery of the connecting seat, the side wall of the main mounting hole is provided with a first card hole, and the connecting seat is provided with a first sliding hole with an open end, the linkage separation mechanism includes a first push block, a first plug piece slidably installed in the first sliding hole, a first elastic member is provided between the first push block and the first plug piece, the two ends of the first elastic member are respectively connected to the first plug piece and the first push block, an electromagnetic controller is also installed on the lock body, the output end of the electromagnetic controller is linked to a swing arm, the middle part of the swing arm is hinged to the lock body, the end of the swing arm away from the electromagnetic controller can push the first push block to move, and the first push block is also linked to a second elastic member.
[0010] Using this technical solution, when the ignition lock needs to be unlocked normally, the electromagnetic controller activates, and the output end pushes the swing arm to rotate about the hinge point. The end of the swing arm away from the electromagnetic controller pushes the first push block into the first sliding hole. The first push block squeezes the first elastic member, compressing it. Simultaneously, the second elastic member is squeezed and compressed by the first push block. When the first insert aligns with the first locking hole, the first elastic member transmits the thrust to the first insert, which then inserts into the first locking hole of the lock cylinder's main mounting hole. At this point, the lock cylinder and the connecting seat are linked by a "first insert-first locking hole" engagement structure. When the knob rotates the lock cylinder, the lock cylinder drives the connecting seat to rotate synchronously through the insert. The connecting seat further drives the rotating shaft, driving the drive plate to control the extension and retraction of the lock tongue, completing the gear shift operation. When the ignition lock is locked, the electromagnetic controller deactivates, the swing arm resets, and the thrust on the first push block is released. The second elastic member stretches and resets, driving the first push block to reset, which in turn drives the first insert out of the first locking hole and retracts into the first sliding hole. At this time, the linkage between the lock core and the connecting seat is disconnected. If a violent unlocker forcibly twists the knob, the knob will be rotated at will. The lock core can only rotate idly on the outer periphery of the connecting seat (there is no engagement constraint between the main mounting hole and the connecting seat), and the torque cannot be transmitted to the connecting seat and the rotating shaft, drive plate and other components, avoiding problems such as knob breakage and pin / rotating shaft damage caused by excessive torsion or impact.
[0011] The above-mentioned ignition lock with idle mode can be further configured as follows: a second sliding hole with an open end is also provided in the connecting seat, the second sliding hole is arranged vertically in a different plane from the first sliding hole, the linkage separation mechanism also includes a second push block, a second plug piece slidably installed in the second sliding hole, a third elastic member is provided between the second push block and the second plug piece, the two ends of the third elastic member are respectively connected to the second plug piece and the second push block, the inner circumference of the lock body is provided with several groups of embedded grooves, and the two sides of the embedded groove are symmetrically provided with first sliding inclined surfaces that facilitate the first push block or the second push block to slide into or out of the embedded groove.
[0012] Using the above technical solution, (i) in the unlocked state, when the electromagnetic controller is started and drives the swing arm to move, the swing arm pushes the first push block. After being pushed by the swing arm, the first push block slides into the corresponding embedded groove along the first sliding slope, and squeezes the first elastic member, pushing the first insert from the first sliding hole and inserting it into the first clamping hole of the main mounting hole of the lock cylinder. At this time, turning the knob will drive the lock cylinder linkage assembly and drive the connecting seat to rotate. During the rotation process, the second push block slides out of the embedded groove along the sliding slope of the embedded groove, that is, the second push block will move toward the second sliding hole, squeeze the third elastic member, and push the second insert from the second sliding hole and insert it into the second clamping hole of the main mounting hole of the lock cylinder. The two sets of inserts jointly link the connecting seat and the lock cylinder, improving the connection reliability between the connecting seat and the lock cylinder. Compared with a single set of inserts, the transmission structure is more solid.
[0013] The above-mentioned ignition lock with idle mode can be further configured as follows: the outer periphery of the connecting seat is provided with a first pushing positioning hole corresponding to the first pushing block, and a second pushing positioning hole is provided corresponding to the second pushing block; the inner end face of the first pushing positioning hole is provided with a first conical positioning column, and the first pushing block is provided with a first cylindrical hole corresponding to the first conical positioning column, which is sleeved on the outer periphery of the first conical positioning column, the second elastic member is inserted into the first cylindrical hole and the second elastic member is sleeved on the outer periphery of the first conical positioning column, and the two ends of the second elastic member are respectively in contact with the inner end face of the pushing positioning hole and the inner end face of the first cylindrical hole; the structure between the second pushing positioning hole and the second pushing block is consistent with the structure between the first pushing positioning hole and the first pushing block.
[0014] With this technical solution, when the swing arm resets, the second elastic member automatically pushes the first push block back into position, improving the sensitivity of the first push block's reciprocating motion and ensuring that the first insert is fully withdrawn from the insertion hole without any jamming. The first conical positioning post cooperates with the first cylindrical hole to guide the expansion and contraction of the second elastic member, preventing it from deflecting or bending. The reset principle of the second push block is the same as that of the first push block and will not be further elaborated here.
[0015] The above-mentioned ignition lock with idle mode can be further configured as follows: a strip mounting hole is provided in the middle of the first plug, the first elastic member is installed in the strip mounting hole, the upper end of the first push block extends into the strip mounting hole, and the upper end of the first push block is provided with a second conical positioning column, one end of the first elastic member is sleeved on the outer periphery of the second conical positioning column and the first elastic member is in contact with the upper end of the first push block, the strip mounting hole is provided with a positioning block corresponding to the other end of the first elastic member, the other end of the first elastic member is sleeved on the outer periphery of the positioning block and the first elastic member is in contact with the strip mounting hole; the structure among the third elastic member, the second push block and the second plug is consistent with the structure among the first elastic member, the first push block and the first plug.
[0016] Using the above technical solution, the second conical positioning column and the positioning block cooperate with each other to ensure that the first elastic member is stably installed in the strip mounting hole. At the same time, the strip mounting hole is used to limit the movement distance of the push block to prevent the first plug from extending too far out of the plug hole or not being plugged in properly (when the first plug is inserted into the plug hole and is in place, the upper end of the first push block will resist one end of the strip mounting hole). Furthermore, when the second elastic member drives the first push block to reset (that is, in the direction in which the first plug exits the plug hole), the upper end of the first push block pushes the end of the strip mounting hole, thereby driving the first plug to reset. The reset principle of the second push block is the same as that of the first push block and will not be repeated here.
[0017] The above-mentioned ignition lock with idle mode can be further configured as follows: the outer sides of the first pushing block and the second pushing block are respectively provided with a second inclined surface, the lower end of the main mounting hole is provided with an inner annular cone surface arranged parallel to the second inclined surface; the lock core linkage unit also includes a lock core sleeve arranged on the outer periphery of the lock core, the upper end of the lock core sleeve is linked to the knob, the lock core is provided with a plurality of groups of blades, the lock core sleeve is provided with a plurality of groups of blade holes for inserting the blades, the lock core sleeve is provided with a lock core mounting hole distributed along its own axial direction, and the inner wall of the lock core mounting hole is provided with at least one group of blade holes along the lock core. A first sliding plane is arranged axially on the core mounting hole, a second sliding plane is provided on the outer periphery of the lock core to cooperate with the first sliding plane, a key hole is provided on the lock core for inserting a key, and at least one group of steel ball mounting holes with openings at both ends are provided on the upper end of the lock core, the steel ball mounting holes are arranged perpendicular to the axial direction of the lock core and are connected to the key hole, a first steel ball is provided in the steel ball mounting hole, a first groove is provided on the key, a second groove is provided on the upper end of the first sliding plane, and the steel ball mounting hole is located at an opening toward the key hole that is smaller than the maximum radial distance of the first steel ball.
[0018] With the above technical solution, a first sliding plane and a second sliding plane are provided between the lock core and the lock core sleeve, which not only enables the key to be pulled out in any gear, but also enables the lock core and the lock core sleeve to rotate coaxially or the lock core to move relative to each other along the axial direction of the lock core sleeve. When the key is inserted, the key cooperates with the steel ball through the first groove to control whether the steel ball falls into the second groove of the lock core sleeve (when the key is inserted, the key groove pushes the steel ball outward and disengages from the second groove, allowing the lock core to move axially; when there is no key or an illegal key, the steel ball is stuck in the second groove of the lock core sleeve, and the lock core cannot move axially). The specific principle is as follows: insert the key until the first groove of the key is aligned with the steel ball mounting hole, and the first steel ball moves toward the keyhole (because the opening of the steel ball mounting hole toward the keyhole is smaller than the diameter of the steel ball, the steel ball will not fall off), so that the steel ball disengages from the second groove of the lock core sleeve, and the lock core can move axially. When the lock core is pressed down, it moves axially. Not only are the blades and the blade holes misaligned, but the inner annular cone below the lock core squeezes the first push block and the second inclined surface on the outside of the second push block, so that both sets of push blocks move toward the connecting seat, and the two sets of inserts are respectively inserted into the two sets of card holes to realize the linkage between the connecting seat and the lock core. The lock core sleeve (linked to the knob) keeps coaxial rotation with the lock core through the cooperation of the first sliding plane and the second sliding plane. Then, the gear switching can be achieved by turning the knob or the key.
[0019] The aforementioned ignition lock with idle mode can be further configured such that: the outer periphery of the connecting seat is further provided with a stop flange surface corresponding to the lower end of the lock core. With this technical solution, the stop flange surface is provided to limit the lock core's position when it moves downward, preventing axial movement of the lock core.
[0020] The above-mentioned ignition lock with idle mode can be further configured as follows: the lower end of the lock cylinder sleeve is sleeved on the outer periphery of the connecting seat, an insert is provided between the connecting seat and the lock cylinder sleeve, a connecting hole is provided on the lock cylinder sleeve that is adapted to one end of the insert, an annular groove is provided on the outer periphery of the connecting seat corresponding to the insert, the other end of the insert is inserted into the annular groove, and barbs are symmetrically provided on both sides of the insert that interfere with the inner peripheral surface of the lock cylinder sleeve.
[0021] With this technical solution, the insert is inserted into the annular groove. This prevents the lock cylinder from moving downward, and also prevents the lock cylinder housing from moving. During idle rotation, the lock cylinder housing drives the insert along the annular groove, preventing the knob or lock cylinder linkage assembly from tilting. The contact force between the barbs and the inner surface of the lock cylinder housing prevents the insert from axially disengaging from the connection hole of the lock cylinder housing.
[0022] The above-mentioned ignition lock with idle mode can be further configured as follows: the upper end of the lock body is connected to a lamp ring mounted on the outer circumference of the knob, the inner circumference of the lamp ring is provided with several groups of positioning grooves, a second steel ball and a fourth elastic member are provided between the knob and the lamp ring, the knob is provided with a first mounting groove corresponding to the second steel ball and the fourth elastic member, the fourth elastic member is inserted into the first mounting groove, and the second steel ball remains in contact with the inner circumference of the lamp ring under the push of the fourth elastic member.
[0023] The above technical solution ensures that the first inserting piece always corresponds to the first card hole and the second inserting piece always corresponds to the second card hole.
[0024] The above-mentioned ignition lock with idle mode can be further configured as follows: a third steel ball and a fifth elastic member are provided between the lock core and the lock core sleeve, the outer circumferential surface of the lock core is provided with a third groove and a fourth groove arranged in sequence along the axial direction of the lock core, a second mounting groove is provided on the lock core sleeve, the fifth elastic member is inserted into the second mounting groove, and the third steel ball remains in contact with the outer circumferential surface of the lock core under the push of the fifth elastic member.
[0025] With this solution, when the lock core moves downward after the key is inserted, the first and second push blocks exert an upward force on the lock core. The third steel ball cooperates with the fifth elastic member to cause the third steel ball to slide from the fourth groove into the third groove during the downward pressure process, thereby limiting the lock core and preventing it from moving upward. When the key is not inserted, that is, when the lock core is not moving downward, the third steel ball is engaged in the fourth groove above.

DETAILED DESCRIPTION
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] like Figures 1 to 12The illustrated ignition lock with an idle mode includes a lock body 1, a knob 2 rotatably connected to the lock body 1, a lock cylinder 6 linkage unit linked to the knob 2, and a rotating shaft 4. A rotor switch is provided on the lock body 1 at the end of the rotating shaft 4 away from the lock cylinder 6 linkage unit. The lock body 1 also includes a drive plate and a lock tongue. The rotating shaft 4 controls the extension and retraction of the lock tongue via the drive plate. A connecting base 5 is provided between the rotating shaft 4 and the lock cylinder 6 linkage unit. The lower end of the connecting base 5 is linked to the rotating shaft 4. A linkage release mechanism is provided between the connecting base 5 and the lock cylinder 6 linkage unit. When the ignition lock is locked, the linkage release mechanism disconnects the connecting base 5 from the lock cylinder 6 linkage unit. When the ignition lock is unlocked, the linkage release mechanism maintains the linkage between the connecting base 5 and the ignition transmission unit, enabling the ignition lock to be switched. The locked state refers to the state in which the ignition lock has not been unlocked by a mechanical key, remote control, or NFC-based electronic control signal (e.g., after the vehicle is turned off and the key / remote control / NFC is not operated). In this state, the linkage release mechanism disconnects the knob 2 from the ignition transmission unit. The unlocked state refers to the state in which the ignition lock is unlocked by means of mechanical key insertion, remote control, or NFC signal-driven electromagnets (e.g., operations before the vehicle ignition). In this state, the linkage release mechanism links the operating unit to the ignition transmission unit. When the ignition lock is locked, the linkage release mechanism disconnects the connection base 5 from the lock cylinder 6. This disconnects the transmission relationship between the knob 2, the lock cylinder 6 linkage assembly, and the connection base 5. If a violent unlocker attempts to rotate the knob 2 in any direction or beyond the specified range, the knob 2 will idle and no power will be transmitted to the connection base 5 and its linked components, such as the rotating shaft 4, the drive plate, and the lock tongue. This prevents impact-induced breakage of the knob 2 or damage to internal components such as the pin and rotating shaft 4. When the ignition lock is unlocked, the linkage release mechanism maintains the connection base 5, the lock cylinder 6 linkage unit, and the knob 2. Knob 2 rotation is transmitted through the lock cylinder 6 linkage unit and the connection base 5 to the rotating shaft 4, allowing the drive plate to normally drive the lock tongue extension and retraction, thus achieving the gear shift function. This design not only ensures the gear operation during normal use, but also effectively resists damage from violent unlocking or arbitrary twisting through the "idling separation" mechanism.
[0031] The lock core linkage unit includes a lock core 6, the lower end of the lock core 6 is provided with a main mounting hole 6a which is sleeved on the outer periphery of the connecting seat 5, and the side wall of the main mounting hole 6a is provided with a first clamping hole 6b, and a first sliding hole 5a with an open end is provided in the connecting seat 5. The linkage separation mechanism includes a first pushing block 7 and a first plug-in piece 8 which is slidably installed in the first sliding hole 5a. A first elastic member 9 is provided between the first pushing block 7 and the first plug-in piece 8, and the two ends of the first elastic member 9 are respectively connected with the first plug-in piece 8 and the first pushing block 7. An electromagnetic controller 10 is also installed on the lock body 1, and the output end of the electromagnetic controller 10 is linked to a swing arm 11. The middle part of the swing arm 11 is hinged to the lock body 1, and the end of the swing arm 11 away from the electromagnetic controller 10 can push the first pushing block 7 to move, and the first pushing block 7 is also linked to a second elastic member 7b.
[0032] When the ignition lock needs to be unlocked normally, the electromagnetic controller 10 is activated, and the output end pushes the swing arm 11 to rotate around the hinge point. The end of the swing arm 11 away from the electromagnetic controller 10 pushes the first push block 7 to move into the first sliding hole 5a; the first push block 7 squeezes the first elastic member 9 to compress it, and at the same time, the first push block 7 squeezes the second elastic member 7b to compress it. When the first insert 8 corresponds to the first locking hole 6b, the first elastic member 9 transmits the thrust to the first insert 8, and the first insert 8 is inserted into the first locking hole 6b of the main mounting hole 6a of the lock cylinder 6. At this time, the lock cylinder 6 and the connecting seat 5 are linked through the "first insert 8-first locking hole 6b" locking structure. When the knob 2 rotates the lock cylinder 6, the lock cylinder 6 drives the connecting seat 5 to rotate synchronously through the insert. The connecting seat 5 further drives the rotating shaft 4 to drive the drive plate to control the extension and retraction of the lock tongue, completing the gear switching operation. When the ignition lock is locked, the electromagnetic controller 10 is deactivated, the swing arm 11 resets, and the thrust on the first pusher 7 is released. The second elastic member 7b stretches and resets, driving the first insert 8 to withdraw from the first engaging hole 6b and retract into the first sliding hole 5a. At this point, the linkage between the lock cylinder 6 and the connecting base 5 is disconnected. If a forcible unlocker forcibly twists the knob 2, the knob 2 will rotate arbitrarily. The lock cylinder 6 can only rotate idly around the outer periphery of the connecting base 5 (the main mounting hole 6a and the connecting base 5 are not engaged), and cannot transmit torque to the connecting base 5, the rotating shaft 4, the drive plate, and other components. This prevents problems such as the knob 2 breaking or the pin / rotating shaft 4 being damaged due to excessive torsion or impact.
[0033] A second sliding hole 5b with an open end is also provided in the connecting seat 5. The second sliding hole 5b is arranged perpendicularly to the first sliding hole 5a in a different plane. The linkage separation mechanism also includes a second pushing block 12 and a second plug piece 13 slidably installed in the second sliding hole 5b. A third elastic member 14 is provided between the second pushing block 12 and the second plug piece 13. The two ends of the third elastic member 14 are respectively connected to the second plug piece 13 and the second pushing block 12. The inner circumferential surface of the lock body 1 is provided with several groups of embedded grooves 1a. The two sides of the embedded groove 1a are symmetrically provided with first sliding inclined surfaces 1b that facilitate the first pushing block 7 or the second pushing block 12 to slide into or out of the embedded groove 1a. (1) In the unlocked state, when the electromagnetic controller 10 is activated and drives the swing arm 11, the swing arm 11 pushes the first push block 7. Pushed by the swing arm 11, the first push block 7 slides along the first sliding slope 1b into the corresponding internal slot 1a, compressing the first elastic member 9 and pushing the first insert 8 out of the first sliding hole 5a and into the first retaining hole 6b of the main mounting hole 6a of the lock cylinder 6. The knob 2 is then rotated, driving the lock cylinder sleeve 16 and the lock cylinder 6 to rotate, which in turn drives the connecting base 5. During this rotation, the second push block 12 slides out of the internal slot 1a along the sliding slope of the internal slot 1a. In other words, the second push block 12 moves into the second sliding hole 5b, compressing the third elastic member 14 and pushing the second insert 13 out of the second sliding hole 5b and into the second retaining hole 6c of the main mounting hole 6a of the lock cylinder 6. The two sets of inserts work together to link the connecting base 5 and the lock cylinder 6, improving the reliability of the connection between the connecting base 5 and the lock cylinder 6. Compared to a single set of inserts, the transmission structure is more secure.
[0034] The outer periphery of the connecting base 5 is provided with a first push positioning hole 5c corresponding to the first push block 7, and a second push positioning hole 5d corresponding to the second push block 12. A first conical positioning post 5e is provided on the inner end surface of the first push positioning hole 5c. The first push block 7 is provided with a first cylindrical hole 7a corresponding to the first conical positioning post 5e, which is sleeved around the outer periphery of the first conical positioning post 5e. A second elastic member 7b is inserted into the first cylindrical hole 7a and sleeved around the outer periphery of the first conical positioning post 5e. The two ends of the second elastic member 7b respectively contact the inner end surfaces of the push positioning hole and the inner end surfaces of the first cylindrical hole 7a. The structure between the second push positioning hole 5d and the second push block 12 is identical to that between the first push positioning hole 5c and the first push block 7. When the swing arm 11 is reset, the second elastic member 7b automatically pushes the first push block 7 back to its original position, improving the sensitivity of the first push block 7's reciprocating movement and ensuring that the first insert 8 is fully withdrawn from the insertion hole without getting stuck. The first conical positioning column 5e cooperates with the first cylindrical hole 7a to guide the expansion and contraction of the second elastic member 7b to prevent the second elastic member 7b from deflecting or bending. The reset principle of the second push block 12 is the same as that of the first push block 7 and will not be repeated here.
[0035] A strip-shaped mounting hole 8a is defined in the middle of the first insert 8. The first elastic member 9 is mounted within this strip-shaped mounting hole 8a. The upper end of the first push block 7 extends into this strip-shaped mounting hole 8a. A second conical positioning post 7c is defined at the upper end of the first push block 7. One end of the first elastic member 9 is sleeved around the outer periphery of the second conical positioning post 7c, and the first elastic member 9 abuts against the upper end of the first push block 7. A positioning block 8b is defined at the other end of the strip-shaped mounting hole 8a, corresponding to the other end of the first elastic member 9. The other end of the first elastic member 9 is sleeved around the outer periphery of the positioning block 8b, and the first elastic member 9 abuts against the strip-shaped mounting hole 8a. The structure of the third elastic member 14, the second push block 12, and the second insert 13 is consistent with that of the first elastic member 9, the first push block 7, and the first insert 8. The second conical positioning post 7c and the positioning block 8b cooperate to ensure that the first elastic member 9 is stably mounted within the strip-shaped mounting hole 8a. At the same time, the strip-shaped mounting hole 8a serves to limit the movement of the push block, preventing the first insert 8 from extending excessively from the insertion hole or from being improperly inserted. (When the first insert 8 is fully inserted into the insertion hole, the upper end of the first push block 7 will contact one end of the strip-shaped mounting hole 8a.) Furthermore, when the second elastic member 7b drives the first push block 7 back to its original position (i.e., in the direction in which the first insert 8 exits the insertion hole), the upper end of the first push block 7 pushes against the end of the strip-shaped mounting hole 8a, thereby driving the first insert 8 back to its original position. The reset principle of the second push block 12 is the same as that of the first push block 7 and will not be further described here.
[0036] The outer sides of the first push block 7 and the second push block 12 are respectively provided with a second inclined surface 15, and the lower end of the main mounting hole 6a is provided with an inner annular cone 6f arranged parallel to the second inclined surface 15; the lock cylinder 6 linkage unit also includes a lock cylinder sleeve 16 sleeved on the outer periphery of the lock cylinder 6, the upper end of the lock cylinder sleeve 16 is linked to the knob 2, the lock cylinder 6 is provided with a plurality of groups of blades, the lock cylinder sleeve 16 is provided with a plurality of groups of blade holes for inserting the blades, the lock cylinder sleeve 16 is provided with a lock cylinder mounting hole 16a distributed along its own axial direction, and the inner wall of the lock cylinder mounting hole 16a is provided with at least one group of lock cylinder mounting holes 16a arranged along the axial direction of the lock cylinder mounting hole 16a. The lock cylinder 6 has a first sliding plane 16b. A second sliding plane 6d is provided on the outer periphery of the lock cylinder 6, which mates with the first sliding plane 16b. The lock cylinder 6 has a keyhole for inserting a key. The upper end of the lock cylinder 6 has at least one set of steel ball mounting holes 6e, open at both ends. The steel ball mounting holes 6e are arranged perpendicular to the axis of the lock cylinder 6 and are in communication with the keyhole. A first steel ball is mounted in each steel ball mounting hole 6e. The key has a first groove 17. A second groove 16c is provided at the upper end of the first sliding plane 16b. The steel ball mounting holes 6e are located at a smaller radial distance from the opening toward the keyhole than the maximum radial distance of the first steel ball. The first sliding plane 16b and the second sliding plane 6d are provided between the lock cylinder 6 and the lock cylinder housing 16. This not only allows the key to be removed in any gear position, but also enables coaxial rotation between the lock cylinder 6 and the lock cylinder housing 16, or relative movement of the lock cylinder 6 along the axis of the lock cylinder housing 16. When the key is inserted, the key engages the steel ball through the first groove 17, controlling whether the steel ball falls into the second groove 16c of the lock cylinder housing 16. (When the key is inserted, the key groove pushes the steel ball outward, disengaging the second groove 16c and allowing the lock cylinder 6 to move axially. When the key is not present or an illegal key is used, the steel ball is trapped in the second groove 16c of the lock cylinder housing 16, preventing the lock cylinder 6 from moving axially.) The specific principle is as follows: the key is inserted until the first groove 17 of the key aligns with the steel ball mounting hole 6e. The first steel ball moves toward the key insertion hole (because the opening of the steel ball mounting hole 6e toward the key insertion hole is smaller than the diameter of the steel ball, the steel ball will not fall out). This causes the steel ball to disengage from the second groove 16c of the lock cylinder housing 16, allowing the lock cylinder 6 to move axially. When the lock core 6 is pressed down, the lock core 6 moves axially. Not only are the blades and the blade holes misaligned, but the inner annular conical surface 6f below the lock core 6 squeezes the first push block 7 and the second inclined surface 15 on the outside of the second push block 12, so that both sets of push blocks will move toward the connecting seat 5, so that the two sets of inserts are respectively inserted into the two sets of card holes, realizing the linkage between the connecting seat 5 and the lock core 6, and the lock core sleeve 16 (linked with the knob 2) keeps coaxial rotation with the lock core 6 through the cooperation of the first sliding plane 16b and the second sliding plane 6d. Then, whether the knob 2 is turned or the key is turned, the gear switching can be achieved.
[0037] The outer periphery of the connecting seat 5 is further provided with a limiting flange surface 5f corresponding to the lower end of the lock core 6. By providing the limiting flange surface 5f, when the lock core 6 moves downward, the lock core 6 is limited to prevent the lock core 6 from moving axially.
[0038] The lower end of the lock cylinder sleeve 16 is sleeved onto the outer periphery of the connecting base 5. An insert 18 is positioned between the connecting base 5 and the lock cylinder sleeve 16. The lock cylinder sleeve 16 has a connecting hole 16d that mates with one end of the insert 18. An annular groove 5g is formed on the outer periphery of the connecting base 5, corresponding to the insert 18. The other end of the insert 18 is inserted into the annular groove 5g. The insert 18 is symmetrically provided on either side with barbs 18a that abut against the inner circumference of the lock cylinder sleeve 16. The insertion of the insert 18 into the annular groove 5g prevents the lock cylinder 6 from moving with the lock cylinder sleeve 16 during downward movement. Furthermore, during idling, the lock cylinder sleeve 16 drives the insert 18 along the annular groove 5g, preventing the knob 2 or the lock cylinder 6 linkage assembly from tilting left or right. The interfering force of the barbs 18a against the inner circumference of the lock cylinder sleeve 16 prevents the insert 18 from axially disengaging from the connecting hole 16d of the lock cylinder sleeve 16.
[0039] The upper end of the lock body 1 is connected to a light ring 19 that fits around the outer circumference of the knob 2. The inner circumference of the light ring 19 is provided with several groups of positioning grooves 20. A second steel ball 21 and a fourth elastic member 22 are provided between the knob 2 and the light ring 19. The knob 2 has a first mounting groove corresponding to the second steel ball 21 and the fourth elastic member 22. The fourth elastic member 22 is inserted into the first mounting groove, and the second steel ball 21 maintains contact with the inner circumference of the light ring 19 under the push of the fourth elastic member 22. Ensure that the first insert 8 always remains aligned with the first engaging hole 6b, and the second insert 13 always remains aligned with the second engaging hole 6c.
[0040] A third steel ball 24 and a fifth elastic member 25 are disposed between the lock core 6 and the lock core housing 16. The outer circumference of the lock core 6 is provided with a third groove 6g and a fourth groove 6h, arranged in sequence along the axial direction of the lock core 6. The lock core housing 16 is provided with a second mounting groove 16e, and the fifth elastic member 25 is inserted into the second mounting groove 16e. The third steel ball 24, pushed by the fifth elastic member 25, remains in contact with the outer circumference of the lock core 6. When the lock core 6 moves downward after the key is inserted, the first push block 7 and the second push block 12 exert an upward force on the lock core 6. The third steel ball 24 cooperates with the fifth elastic member 25, causing it to slide from the fourth groove 6h into the third groove 6g during the downward pressure process, thereby limiting the lock core 6 and preventing it from moving upward. When the key is not inserted, that is, when the lock core 6 is not moving downward, the third steel ball 24 is retained in the upper fourth groove 6h.
[0041] The connecting base 5 is linked to a pressure piece 23. The lock body 1 is provided with a microswitch 3. The pressure piece 23 can contact the contacts of the microswitch 3 to activate the microswitch 3. The lock body 1 is provided with a spring that can drive the connecting base 5 and the rotating shaft 4 to reset. The lock body 1 is provided with a microswitch 3. Only after the microswitch 3 is triggered and opened can the electromagnetic controller 10 operate to cause the swing arm 11 to swing. Before rotating the knob 2, the knob 2 is first pushed into the lock body 1, synchronously moving the lock cylinder 6 and the connecting base 5, which in turn synchronously drives the pressure piece 23 until the pressure piece 23 contacts the contacts of the microswitch 3, activating the microswitch 3. Then, under the action of the spring, it drives the connecting base 5 and the rotating shaft 4 to reset. At this time, the knob 2 is rotated again to realize keyless starting and stopping operations. Keyless starting can only be carried out after the microswitch 3 is first activated, which can effectively prevent various misoperations, such as accidental opening by children playing, and is safer and more reliable.
[0042] Working principle of this embodiment: When the electric unlocking mode is keyless / remote controlless / NFC-free, the first insert piece 8 and the second insert piece 13 are not inserted into the first card hole 6b and the second card hole 6c respectively, and the lock core 6 does not move downward under the action of the blade and the blade hole, and will not squeeze the two pushing blocks. At this time, the connecting seat 5 and the lock core 6 are in a separated state. When the knob 2 is turned, the knob 2 will drive the lock core 6 and the lock core sleeve 16 to rotate idly around the outer periphery of the connecting seat 5. Therefore, it can cope with the state of violent or random rotation of the knob 2, with stronger anti-theft performance and safer ignition lock.
[0043] When unlocking with a key: The key is inserted until the blade exits the blade slot. Then, the lock cylinder 6 is pressed downward, causing the lock cylinder 6 to move axially relative to the lock cylinder sleeve 16. The inner annular conical surface 6f at the lower end of the lock cylinder 6 compresses the second inclined surface 15 on the outer sides of the first push block 7 and the second push block 12, causing both sets of push blocks to move toward the connecting seat 5. The two sets of inserts are then inserted into the two sets of locking holes, achieving linkage between the connecting seat 5 and the lock cylinder 6. The lock cylinder sleeve 16 (linked to the knob 2) rotates coaxially with the lock cylinder 6 through the cooperation of the first sliding surface 16b and the second sliding surface 6d. Subsequently, whether the knob 2 is turned or the key is turned, the gear can be switched. After the key is inserted, when the lock cylinder 6 moves downward, the first push block 7 and the second push block 12 exert an upward force on the lock cylinder 6. The third steel ball 24 cooperates with the fifth elastic member 25, causing the third steel ball 24 to slide from the fourth groove 6h into the third groove 6g during the downward pressure, limiting the lock cylinder 6 and preventing it from moving upward.
[0044] When using an electronic unlocking method such as remote control or NFC: first press down on knob 2, which drives lock cylinder 6 downward through lock cylinder sleeve 16 (the three move downward synchronously), pushes connecting seat 5 downward, and pushes pressure plate 23 downward, triggering microswitch 3 (after releasing knob 2, knob 2 will automatically reset axially). Electromagnetic controller 10 is activated, and drives swing arm 11 to swing. The upper end of swing arm 11 pushes first push block 7, and first insert 8 inserts into first latch hole 6b. In this state, connecting seat 5 has maintained its initial linkage with lock cylinder 6. Next, turn knob 2. During this rotation, the first sliding slope 1b on the side of the embedded groove 1a on the inner circumference of lock body 1 will squeeze second push block 12. Second push block 12 not only exits one set of embedded grooves 1a, but also pushes second insert 13 into second latch hole 6c, realizing the linkage between the two inserts and connecting seat 5, and strengthening the linkage relationship between lock cylinder 6 and connecting seat 5.
[0045] The special thing is: when switching to the front gear of locking the vehicle, the first push block 7 will follow the connecting seat 5 to rotate 90 degrees counterclockwise, so that it will not correspond to the swing arm 11, and the second push block 12 will follow the connecting seat 5 to rotate 90 degrees counterclockwise, so the second push block 12 will rotate to correspond to the swing arm 11. When there is an electric unlocking method such as remote control / NFC, the electromagnetic controller 10 is started, so that the swing arm 11 will squeeze the second push block 12, so that the second insert 13 will be inserted into the second card hole 6c, and the connecting seat 5 and the lock cylinder 6 will be linked, so that the knob 2 can be rotated and the knob 2 can be reset axially.
