Description

Technical Field

[0001] The invention relates to an ignition switch lock, which is mainly used on motorcycles or electric vehicles. Background Art

[0002] The ignition switch lock of the keyless system is suitable for ignition, flameout and locking of motorcycles or electric vehicles. This ignition switch has the same three basic functions of "ON, OFF, LOCK" required by the vehicle as the traditional similar products. However, the keyless system has defects. When the electromagnetic controller that receives the electronic signal fails, the motorcycle or electric vehicle will not be able to start. Therefore, an ignition switch lock combining keyless start and key start has appeared. For example, the relevant literature announcement numbers CN206558419U and CN207765361U disclose an ignition switch lock combining keyless start and key start. The ignition switch lock combined with start mainly has a lock core sleeve installed outside the lock core. In the keyless state, when the electromagnetic controller works normally, it can control the pin to retract, thereby unlocking the lock core sleeve, and then by rotating the handle, the blades that pop up on the lock core can drive the lock core sleeve to rotate together to realize the various functions of the ignition switch; and when the electromagnetic controller fails and cannot control the pin to retract, that is, the lock core sleeve cannot be unlocked, by inserting the key, the pop-up blades will be retracted into the lock core, so that the lock core and the lock core sleeve are separated, and then the various functions of the ignition switch lock are realized by rotating the lock core alone. However, these existing structures all require a lock core sleeve that is compatible with the lock core to be customized, which is difficult to process, has high manufacturing costs, and has poor anti-theft performance. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a multifunctional ignition switch smart lock which is easy to process, has low manufacturing cost, and has better anti-theft performance and is easy to install.

[0004] To achieve the above-mentioned purpose, the present invention provides a multifunctional ignition switch intelligent lock, including a handle, a lock core and a lock body, wherein the lock core is rotatably arranged in the lock body, the handle and the lock core are linked and cooperated, a switch assembly driven by the lock core is arranged on the lock body, and an electromagnetic controller is also arranged on the lock body, wherein the electromagnetic controller includes a housing and a bolt, the bolt is inserted in the housing and connected with a spring to cause it to extend out of the housing, and an electromagnetic coil is also arranged in the housing to drive the bolt to overcome the spring force and retract into the housing after it is energized, and a radial insertion force for the bolt is provided on the lock core. The ignition switch lock further comprises a socket for insertion, a pin head abutting against the bolt is arranged in the socket, a key core matched with the key core is inserted in the lock core, a first pin hole matched with the pin head is arranged on the key core, and when the pin head matches with the first pin hole, the bolt can be inserted into the socket; the ignition switch lock also comprises a spare key core matched with the lock core, a second pin hole matched with the pin head is arranged on the spare key core, the depth of the second pin hole is shallower than that of the first pin hole, and when the pin head matches with the second pin hole, the pin head pushes the bolt out of the socket.

[0005] With the above structure, under normal circumstances, the key core is always placed in the lock core and rotates with the lock core. During this process, the latch of the electromagnetic controller can be inserted into the jack of the lock core. When the latch of the electromagnetic controller is inserted into the jack of the lock core, the electromagnetic controller will lock the lock core, that is, limit the rotation of the lock core; when the electromagnetic controller receives an external unlocking signal, the electromagnetic coil is energized, thereby driving the latch to overcome the spring force and shrink into the shell, that is, the latch is pulled out of the jack of the lock core, and the lock core can be rotated. At this time, the handle drives the lock core to rotate together, and various functions of the ignition switch lock can be realized. When the electromagnetic controller fails, it cannot control the bolt to be pulled out of the socket of the lock core. At this time, the key core can be taken out and the spare key core can be inserted. The difference between the key core and the spare key core is that the depth of the first pin hole on the key core is different from the depth of the second pin hole on the spare key core, that is, the depth of the second pin hole is shallower than the depth of the first pin hole. Therefore, after the spare key core is inserted, the pin head cooperates with the second pin hole, and the pin head will push the bolt out of the socket, that is, the pin overcomes the spring force and shrinks into the shell, so that the pin loses the locking limit of the lock core. At this time, the lock core is driven to rotate together by the handle, so that various functions of the ignition switch lock can be realized.

[0006] The beneficial effects of the present invention are: since the present invention only needs to process pin holes of different depths on the key core and the spare key core, the ignition and other operations of the electromagnetic controller can be realized in both normal operation and failure conditions. Compared with the existing structure that requires customization of a lock core sleeve that is compatible with the lock core, the processing is more convenient and the manufacturing cost is lower.

[0007] The present invention can be further configured such that a plurality of pins are arranged on the lock core, pin holes matching the pins are arranged on the key core and the spare key core, and the pins are further connected to a first spring to force them to enter the pin holes. By providing a structure in which multiple groups of pins are matched with the pin holes, the anti-theft performance can be greatly improved.

[0008] The present invention can be further configured so that the handle is rotatably arranged on the end cover, the end cover is provided with a mounting portion which is sleeved on the lock body, the lock body is provided with a protrusion, the mounting portion is provided with an opening for axial insertion of the protrusion, a side surface of the opening is provided with a slot which forms a snap connection with the protrusion after the mounting portion is rotated, and a stop structure is also provided between the mounting portion and the lock body to limit the mounting portion after it is rotated.

[0009] With the above structure, when installing the end cover, first the opening on the mounting portion is axially plugged into the protrusion, and then the mounting portion is rotated to make the protrusion snap into the slot on one side of the opening, and finally the mounting portion is restricted from rotating further by the stop structure, so that the end cover can be fixedly installed. Compared with the traditional complicated installation method, the present invention is more convenient to install and has a simpler structure.

[0010] The present invention can be further configured such that the anti-retraction structure includes a bolt and a slider slidably arranged on the lock body. After the mounting portion is inserted into the lock body and rotated, one end of the slider is inserted into the opening of the mounting portion along the axial direction of the mounting portion, and forms abutment with the other side surface of the opening opposite to the opening where the slot is provided. A second spring is arranged between the other end of the slider and the lock body. A long groove is provided on the slider along its sliding direction. The screw body of the bolt passes through the long groove and is screwed and fixed to the lock body, and the screw head of the bolt presses against the slider.

[0011] With the above structure, when the end cover mounting portion is axially plugged into the protrusion on the lock body, the end cover mounting portion first pushes the slider to slide backward, that is, the slider moves in the direction of overcoming the force of the second spring; and after the mounting portion is plugged into the lock body and rotated, that is, at this time, the protrusion on the lock body is inserted into the said slot, one end of the slider is inserted into the opening of the mounting portion along the axial direction of the mounting portion, and forms abutment with the other side of the opening opposite to the slot, thereby limiting the further rotation of the mounting portion and the end cover, that is, effectively preventing the protrusion from sliding out of the slot, and then achieving fixed installation of the end cover. In addition, the action of the bolt allows the slider to only slide linearly relative to the lock body, and the structure is more stable and reliable.

[0012] The present invention can be further configured to have a first rotating member and a second rotating member between the handle and the end cover, a keyhole for the key core and the spare key core to pass through and adapted thereto being provided on the first rotating member, a first limiting structure for linkage being provided between the first rotating member and the lock core, a second limiting structure for linkage being provided between the second rotating member and the handle, a through hole for the key core and the spare key core to pass through being provided on the second rotating member, the second rotating member being rotatably arranged in the first rotating member, a third limiting structure for linkage being provided between the first rotating member and the second rotating member, the third limiting structure comprising a steel ball and a third spring, an axial accommodating groove for accommodating the steel ball and the third spring being provided on the second rotating member, and the steel ball extending out of the axial accommodating groove under the action of the third spring, and a positioning groove for embedding the steel ball is provided on the first rotating member.

[0013] With the above structure, the first rotating member is fixed to the lock core and the key core or the spare key core, and the second rotating member is fixed to the handle. Since the third limiting structure between the first rotating member and the second rotating member is composed of a steel ball and a third spring, when the motorcycle or electric vehicle is in a locked state, that is, the lock core cannot rotate, if criminals want to rotate the lock core to ignite by forcefully rotating the handle, the steel ball will fall out of the positioning groove, thereby losing the connection between the first rotating member and the second rotating member. That is, when people rotate the handle forcefully, they can only rotate the second rotating member together, while the first rotating member, the lock core and the key core or the spare key core will not rotate accordingly, thereby greatly improving the anti-theft performance and protecting the lock core.

[0014] The present invention can be further configured such that the first limiting structure includes a limiting protrusion and a limiting groove that are plugged into each other, and the limiting protrusion and the limiting groove are respectively arranged on the first rotating member and the lock core. Through the cooperation of the limiting protrusion and the limiting groove, the first rotating member and the lock core can be fixed together and linked after being assembled.

[0015] The present invention can be further configured such that the second limiting structure includes a positioning pin, a fourth spring and a connecting block arranged on the second rotating member, the connecting block is provided with a radial receiving groove for accommodating the positioning pin and the fourth spring, and the positioning pin extends out of the radial receiving groove under the action of the fourth spring, and the handle is provided with a connecting hole for the positioning pin to be inserted. Through the cooperation of the positioning pin and the connecting hole, the handle and the second rotating member can be fixed together and linked after being assembled, and at the same time, by pressing the positioning pin, even if the positioning pin overcomes the action of the fourth spring and comes out of the connecting hole, the handle and the second rotating member can be separated, that is, the handle can be removed, thereby realizing the replacement between the key core and the spare key core, and the structure is simple and the replacement is convenient.

[0016] The present invention can be further configured such that the first rotating member is provided with a plurality of coaxial first convex rings, and the second rotating member is provided with a plurality of coaxial second convex rings, and the first convex rings and the second convex rings are mutually staggered and form a plug-in fit. Through the above configuration, the first rotating member and the second rotating member can form a more reliable connection, so that the first rotating member and the second rotating member can be better linked.

[0031] like Figure 1-14The figure shows a multifunctional ignition switch intelligent lock, including a handle 1, a lock core 2 and a lock body 3. The lock core 2 is rotatably arranged in the lock body 3, and the handle 1 is linked with the lock core 2. A switch assembly driven by the lock core 2 is arranged on the lock body 3. The switch assembly may specifically include a rotor switch 5, a micro switch 6 and a latch 4. A rotating shaft 7 for driving the rotor switch 5 to rotate is rotatably arranged in the lock body 3. The rotation of the rotor switch 5 is used to control the ignition and shutdown of a motorcycle or an electric vehicle. The rotating shaft 7 is linked with the lock core 2 and can move axially along the lock core 2. Specifically, one end 71 of the rotating shaft 7 is flatly arranged, and a flat slot 21 is arranged at one end of the lock core 2. The flat slot 21 is adapted to one end 71 of the rotating shaft 7. A paddle 22 is also arranged on the lock core 2. After the paddle 22 moves axially with the lock core 2, the micro switch 6 can be pressed. A driving plate 72 is also connected to the rotating shaft 7. After the rotating shaft 7 rotates, the driving plate 72 can be driven to pull the latch 4 to retract or retract.

[0032] The lock body 3 is also provided with an electromagnetic controller 8, which includes a housing 81 and a latch 82. The latch 82 is inserted in the housing 81 and connected to a spring 83 that causes it to extend out of the housing 81. The housing 81 is also provided with an electromagnetic coil 84 that drives the latch 82 to contract into the housing 81 after power is turned on, overcoming the force of the spring 83. The lock core 2 is provided with a socket 23 for radial insertion of the latch 82. The socket 23 is provided with a pin head 24 that abuts against the latch 82. The lock core 2 is provided with a key core 9 that matches it. The key core 9 is provided with a first pin hole 91 which matches with the pin head 24, and when the pin head 24 matches with the first pin hole 91, the latch 82 can be inserted into the insertion hole 23; the ignition switch lock also includes a spare key core 10 adapted to the lock core 2, and the spare key core 10 is provided with a second pin hole 101 which matches with the pin head 24, the depth of the second pin hole 101 is shallower than the depth of the first pin hole 91, and when the pin head 24 matches with the second pin hole 101, the pin head 24 pushes the latch 82 out of the insertion hole 23.

[0033] With the above structure, under normal circumstances, the key core 9 is always placed in the lock core 2 and rotates with the lock core 2. During this process, the latch 82 of the electromagnetic controller 8 can be inserted into the insertion hole 23 of the lock core 2. When the latch 82 of the electromagnetic controller 8 is inserted into the insertion hole 23 of the lock core 2, the electromagnetic controller 8 will lock the lock core 2, that is, limit the rotation of the lock core 2; when the electromagnetic controller 8 receives an external unlocking signal, the electromagnetic coil 84 is energized, thereby driving the latch 82 to overcome the force of the spring 83 and shrink into the housing 81, that is, the latch 82 is pulled out of the insertion hole 23 of the lock core 2, and the lock core 2 can rotate. At this time, the handle 1 drives the lock core 2 to rotate together, and various functions of the ignition switch lock can be realized. When the electromagnetic controller 8 fails, that is, it cannot control the latch 82 to be pulled out from the insertion hole 23 of the lock core 2. At this time, the key core 9 can be taken out and the spare key core 10 can be inserted. The difference between the key core 9 and the spare key core 10 is that the depth of the first pin hole 91 on the key core 9 is different from the depth of the second pin hole 101 on the spare key core 10, that is, the depth of the second pin hole 101 is shallower than the depth of the first pin hole 91. Therefore, after the spare key core 10 is inserted, the pin head 24 cooperates with the second pin hole 101, and the pin head 24 will push the latch 82 out of the insertion hole 23, that is, the latch 82 overcomes the force of the spring 83 and shrinks into the shell 81, so that the latch 82 loses the locking limit on the lock core 2. At this time, the lock core 2 is driven to rotate together by the handle 1, so that various functions of the ignition switch lock can be realized.

[0034] With this arrangement, since the present invention only needs to process pin holes of different depths on the key core 9 and the spare key core 10, the ignition and other operations of the electromagnetic controller 8 can be realized in both normal operation and failure conditions. Compared with the existing structure that requires a customized lock core sleeve that is compatible with the lock core 2, the processing is more convenient and the manufacturing cost is lower.

[0035] The lock cylinder 2 is provided with a plurality of pins 25, and the key cylinder 9 and the spare key cylinder 10 are provided with corresponding pin holes 26 that match the pins 25. The pins 25 are also connected with a first spring 27 that forces them to enter the pin holes 26. By providing a structure in which multiple groups of pins 25 are matched with the pin holes 26, the anti-theft performance can be greatly improved.

[0036] The handle 1 is rotatably arranged on the end cover 11, and a mounting portion 111 which is sleeved on the lock body 3 is provided on the end cover 11, and a protrusion 31 is provided on the lock body 3. The mounting portion 111 is provided with an opening 112 for axial insertion of the protrusion 31, and a slot 113 which is engaged with the protrusion 31 after the mounting portion 111 is rotated is provided on one side surface of the opening 112, and a stop structure which limits the mounting portion 111 after it is rotated is also provided between the mounting portion 111 and the lock body 3.

[0037] With the above structure, when the end cover 11 is installed, the opening 112 on the mounting portion 111 is first inserted into the protrusion 31 along the axial direction, and then the mounting portion 111 is rotated to make the protrusion 31 snap into the slot 113 located on one side of the opening 112. Finally, the mounting portion 111 is restricted from rotating further by the stop structure, so that the end cover 11 can be fixedly installed. Compared with the traditional complicated installation method, the present invention is more convenient to install and has a simpler structure.

[0038] The anti-retraction structure includes a bolt 12 and a slider 13 slidably arranged on the lock body 3. After the mounting portion 111 is inserted into the lock body 3 and rotated, one end of the slider 13 is axially inserted into the opening 112 of the mounting portion 111 along the mounting portion 111, and forms abutment with the other side surface 114 of the opening 112 provided with a slot 113. A second spring 131 is arranged between the other end of the slider 13 and the lock body 3. A long groove 132 is opened on the slider 13 along its sliding direction. The screw body of the bolt 12 passes through the long groove 132 and is screwed and fixed on the lock body 3. The screw head of the bolt 12 presses against the slider 13.

[0039] With the above structure, when the end cover mounting portion 111 is axially plugged with the protrusion 31 on the lock body 3, the mounting portion 111 of the end cover 11 first pushes the slider 13 to slide backward, that is, the slider 13 moves in the direction of overcoming the force of the second spring 131; and after the mounting portion 111 is plugged into the lock body 3 and rotated, that is, at this time, the protrusion 31 on the lock body 3 is inserted into the said slot 113, one end of the slider 13 is axially inserted into the opening 112 of the mounting portion 111 along the mounting portion 111, and forms abutment with the other side surface 114 of the opening 112 where the slot 113 is provided, thereby limiting the further rotation of the mounting portion 111 and the end cover 11, that is, effectively preventing the protrusion 31 from sliding out of the slot 113, thereby achieving the fixed installation of the end cover 11. In addition, the action of the bolt 12 makes the slider 13 only slide linearly relative to the lock body 3, and the structure is more stable and reliable.

[0040] A first rotating member 14 and a second rotating member 15 are arranged between the handle 1 and the end cover 11, and a key hole 141 is arranged on the first rotating member 14 for the key core 9 and the spare key core 10 to pass through and match therewith, a first limiting structure that is linked to each other is arranged between the first rotating member 14 and the lock core 2, and a second limiting structure that is linked to each other is arranged between the second rotating member 15 and the handle 1, a through hole 151 is provided on the second rotating member 15 for the key core 9 and the spare key core 10 to pass through, the second rotating member 15 is rotatably arranged in the first rotating member 14, and a third limiting structure that is linked to each other is arranged between the first rotating member 14 and the second rotating member 15, and the third limiting structure includes a steel ball 16 and a third spring 17, an axial accommodating groove 152 for accommodating the steel ball 16 and the third spring 17 is provided on the second rotating member 15, and the steel ball 16 extends out of the axial accommodating groove 152 under the action of the third spring 17, and a positioning groove 142 for the steel ball 16 to be embedded is provided on the first rotating member 14.

[0041] With the above structure, the first rotating member 14 is fixed to the lock core 2 and the key core 9 or the spare key core 10, and the second rotating member 15 is fixed to the handle 1. Since the third limiting structure between the first rotating member 14 and the second rotating member 15 is composed of a steel ball 16 and a third spring 17, when the motorcycle or electric vehicle is in a locked state, that is, the lock core 2 cannot rotate, if the criminals want to rotate the lock core 2 by rotating the handle 1 to ignite the engine, the steel ball 16 will fall out of the positioning groove 142, thereby losing the connection between the first rotating member 14 and the second rotating member 15, that is, when people rotate the handle 1 with force, they can only rotate the second rotating member 15 together, while the first rotating member 14, the lock core 2 and the key core 9 or the spare key core 10 will not rotate with it, thereby greatly improving the anti-theft performance and protecting the lock core 2.

[0042] The first limiting structure includes a limiting protrusion 143 and a limiting groove 28 that are plugged into each other, and the limiting protrusion 143 and the limiting groove 28 are respectively arranged on the first rotating member 14 and the lock core 2. Through the cooperation of the limiting protrusion 143 and the limiting groove 28, the first rotating member 14 and the lock core 2 can be fixed together and linked after being assembled.

[0043] The second limiting structure includes a positioning pin 18, a fourth spring 19 and a connecting block 153 disposed on the second rotating member 15. A radial receiving groove 154 for receiving the positioning pin 18 and the fourth spring 19 is provided on the connecting block 153, and the positioning pin 18 extends outward from the radial receiving groove 154 under the action of the fourth spring 19. A connecting hole 102 for inserting the positioning pin 18 is provided on the handle 1. Through the cooperation between the positioning pin 18 and the connecting hole 102, the handle 1 and the second rotating member 15 can be fixed together and linked after being assembled. At the same time, by pressing the positioning pin 18, even if the positioning pin 18 overcomes the action of the fourth spring 19 and comes out of the connecting hole 102, the handle 1 and the second rotating member 15 can be separated, that is, the handle 1 can be removed, thereby realizing the replacement between the key core 9 and the spare key core 10, with a simple structure and convenient replacement.

[0044] The first rotating member 14 is provided with a plurality of coaxial first convex rings 144, and the second rotating member 15 is provided with a plurality of coaxial second convex rings 155. The first convex rings 144 and the second convex rings 155 are mutually staggered and form a plug-in fit. Through the above arrangement, the first rotating member 14 and the second rotating member 15 can form a more reliable connection, so that the first rotating member 14 and the second rotating member 15 can be better linked.
