Description

Technical Field

[0001] This utility model relates to an improved ignition switch lock that can be started with or without a key. Background Technology

[0002] The ignition switch lock, which can be started with or without a key, includes components such as a knob, a lock cylinder, a lock cylinder sleeve, a lock cylinder sleeve locking device, and a rotor switch. When the matching key is inserted into the lock cylinder through the knob and manually turned, the rotor switch will rotate accordingly to start the two-wheeled electric vehicle or motorcycle. If the matching key is not carried, the owner can first press the knob to release the lock cylinder sleeve locking device from locking the lock cylinder sleeve, and then turn the knob to make the lock cylinder and lock cylinder sleeve rotate synchronously, and the rotor switch will also rotate accordingly to start the two-wheeled electric vehicle or motorcycle. When the lock cylinder sleeve locking device releases its locking effect on the lock cylinder sleeve, the lock cylinder sleeve needs to rotate during ignition and shutdown. Existing structural designs use multiple sets of spring balls at the rotor switch to indirectly limit the rotation angle of the lock cylinder sleeve. Due to the accumulation of dimensional tolerances between multiple linkage components, after assembly or during use, if there is a certain deviation in the position of the lock cylinder sleeve, the locking rod of the lock cylinder sleeve locking device may not fall accurately into the corresponding locking rod groove on the lock cylinder sleeve, which may result in a situation where locking is not possible.

The rotor 71 and the electric transmission plate 73 on the shaft rotate relative to the bakelite insert 74, realizing ignition and flameout control.

[0032] Keyless unlocking: The car owner presses the knob inward, and the trigger plate moves axially with the lock cylinder, causing the micro switch to receive a signal and activate the lock cylinder sleeve locking device. The locking rod 204 rises away from the locking rod groove 131 of the lock cylinder sleeve 13, thus releasing the lock cylinder sleeve 13 from locking. At this time, turning the knob causes the lock cylinder, lock cylinder sleeve, and rotating shaft to rotate synchronously. The rotor 71 and the electric transmission plate 73 on the rotating shaft rotate relative to the bakelite insert 74, realizing ignition and shutdown control. When unlocking without a key, it is necessary to distinguish between the car owner's pressing action and other people's pressing actions. That is, the car owner's pressing action can realize the unlocking control of the lock cylinder sleeve locking device, while other people's pressing actions will not trigger the lock cylinder sleeve locking device. In actual design, the car owner usually has a signal transmitting device, such as a mobile phone Bluetooth. The ignition switch lock has a receiving module inside to receive the car owner's signal. The receiving module is connected in series with the control circuit of the lock cylinder sleeve locking device, so as to realize that it only responds to the valid actions of the car owner.
