Description

Multifunctional ignition lock with mechanical failure unlocking function

Technical Field

The invention relates to a locomotive ignition lock, in particular to a multifunctional ignition lock with a mechanical fault unlocking function.

Background

The existing ignition lock for locomotive (motorcycle and electric vehicle) is mainly composed of lock shell, lock core in the lock shell, rotating shaft linked with the lock core and lock tongue linked with the rotating shaft. In order to make such ignition locks realize keyless starting based on the original mechanical ignition, those skilled in the art install an electromagnetic controller on the lock case, wherein the electromagnetic controller is composed of an electromagnetic coil and an electromagnetic bolt.

See patent No. ZL2018010129844.4, filed as: on the year 02/08 in 2018, the patent name "an ignition lock which can be started without a key and with a key" is visible. The ignition switch lock comprises a knob, a lock core and a lock body, wherein the lock core is rotatably arranged in the lock body, the knob is in linkage connection with the lock core, a rotating shaft is arranged in the lock body and can move along the axial direction of the lock core and is in linkage connection with the lock core, a rotor switch is arranged at the end part of the lock body, which is far away from one side of the lock core, of the rotating shaft, a driving sheet and a plunger latch are further arranged on the lock body, the driving sheet is connected with the plunger latch and can drive the driving sheet to move to realize the extension and retraction movement of the plunger latch, an electromagnetic controller is arranged on the lock body and is provided with a pin shaft, the electromagnetic controller can control the pin shaft to extend and retract, a blade groove is formed in the lock core, a blade matched with a key is arranged in the blade groove, a rotatable lock core sleeve is sleeved on the periphery of the lock core, when the lock pin is not inserted into the key matched with the lock pin, the lock pin is linked with the lock pin sleeve, the lock pin sleeve and the lock pin are controlled by the electromagnetic controller, when the pin shaft is separated from the pin shaft groove, the rotary knob drives the lock pin and the lock pin sleeve to rotate so as to drive the rotary shaft to rotate, and when the pin shaft is inserted into the pin shaft groove, the lock pin and the lock pin sleeve are locked; when the lock core is inserted into a key matched with the lock core, the blade is separated from the clamping groove or the clamping hole of the lock core sleeve, the lock core can rotate in the lock core sleeve, and the key is rotated to drive the lock core to rotate so as to drive the rotating shaft to rotate. The principle is as follows: the knob is linked with the lock core to drive the lock core to rotate and drive the lock core to move along the axial direction, the rotating shaft is linked with the lock core to drive the lock core to rotate and drive the rotating shaft to move, a coil and a driving spring are arranged in the electromagnetic controller, the coil can overcome the acting force of the driving spring to suck the pin shaft and separate from the pin shaft groove after being electrified, the coil is powered off, the pin shaft extends out and is inserted into the pin shaft groove under the action of the driving spring, the electromagnetic controller can control the unlocking and locking of the lock core sleeve when being electrified, the lock core is not inserted into a key matched with the lock core, the blade in the lock core extends out of the blade groove and can be just clamped in the clamping groove or the clamping hole of the lock core sleeve, the linkage of the lock core and the lock core sleeve is realized, when the electromagnetic controller works normally, the pin shaft is controlled by the electromagnetic controller to separate from, the rotation of the rotating shaft can drive a rotor switch to perform keyless starting operation, and can also drive the lock cylinder to rotate through the knob, the lock cylinder drives the rotating shaft to rotate, and the rotating shaft drives the driving piece to move to realize telescopic movement of the lock latch and perform vehicle locking operation; when the electromagnetic controller cannot work normally, the electromagnetic controller cannot control the pin shaft to be separated from the pin shaft groove, the lock cylinder and the lock cylinder sleeve are linked and arranged, the lock cylinder cannot rotate and cannot be started without a key, the lock cylinder is inserted into a key matched with the lock cylinder, the blades are separated from a clamping groove or a clamping hole of the lock cylinder sleeve, the lock cylinder can rotate in the lock cylinder sleeve, the key is rotated to drive the lock cylinder to rotate, the rotating shaft is driven to rotate, the rotating shaft can drive the rotor switch to perform key starting operation, and the lock cylinder sleeve are matched with each other. When the electromagnetic controller fails and the pin shaft in the electromagnetic brake cannot unlock the lock cylinder sleeve, the lock cylinder is inserted into a matched key to release the connection between the lock cylinder sleeve and the lock cylinder, so that the lock cylinder is rotated, and the lock cylinder is linked with the rotating shaft to control the latch, thereby unlocking the locomotive. However, the internal structure is not only complex, inconvenient to assemble and high in cost. When the electromagnetic controller fails, the lock cylinder must be controlled by a key, and a spare key is not always carried under the condition that an operator uses keyless driving for a long time, namely, the operator is used to the keyless driving. Therefore, when the spare unlocking key is not carried and the electromagnetic relay fails, the operator still cannot unlock the electromagnetic relay.

To overcome the above technical drawbacks, the applicant filed application No. 202010796231.3 entitled "keyless-start ignition switch lock with alternative unlocking function" on 10/08/2020, which discloses a keyless-start ignition switch lock with alternative unlocking function, the lock comprises a lock body, a knob arranged on the lock body, a rotating shaft which is positioned in the lock body and is linked with the knob to slide in a reciprocating way along the axial direction of the lock body and rotate in the circumferential direction, and a plunger latch which is linked with the rotating shaft to realize locking or unlocking, wherein an electromagnetic controller is arranged on the lock body, a telescopic pin shaft after being electrified is arranged on the electromagnetic controller, a circumferential limiting groove matched with the pin shaft is arranged on the rotating shaft, when the electromagnetic controller fails, a rotary knob is arranged between the knob and the lock, the pushing piece can move towards the pin shaft and can make the pin shaft break away from the circumferential limiting groove to release circumferential locking on the rotating shaft, and the knob is provided with a coded lock assembly for locking or unlocking the pushing piece. It has replaced traditional mechanical lock core through the trick lock subassembly, has not only reduced spare part, makes cost reduction, when the lock body broke down moreover, need not to implement the unblock through the key, and the unblock mode is simple swift.

With the continuous development of such ignition locks, manufacturers and entire car manufacturers have more and higher requirements for their unlocking functions. If direct realization unblock such as cushion and the fuel tank cap of passing through the ignition lock to the locomotive, and can guarantee simultaneously that its volume does not receive the change, the difficult problem that technical personnel in this field can't overcome always.
