Description

Technical Field

[0001] The utility model relates to the technical field of ignition locks, in particular to a locomotive central control lock. Background Art

[0002] The ignition lock is a multi-position switch, which is usually used to control the power on or off of electric vehicles or motorcycles, lock the steering wheel, etc. There are ignition locks on the market that combine keyless start and key start. This ignition lock can be called a central lock.

[0003] Existing vehicle bodies usually have a seat cushion lock, a fuel tank lock and a front tool box lock. A general ignition lock will include an unlocking mechanism for opening the seat cushion lock, the fuel tank lock or the front tool box lock. For example, the utility model patent with patent application number CN201920990423.0 discloses a small ignition switch lock, including a knob, a lock core and a lock body. The lock core is rotatably arranged in the lock body, the knob is linked to the lock core, a rotating shaft is rotatably arranged in the lock body, the rotating shaft can move along the axial direction of the lock core, the rotating shaft is linked to the lock core, a rotor switch is provided at the end position of the lock body on the side of the rotating shaft away from the lock core, a blade groove is provided on the lock core, a blade matching the key is provided in the blade groove, a lock core sleeve is provided on the outer peripheral sleeve of the lock core, and the lock core The sleeve is rotatably arranged in the lock body, and the lock core sleeve is provided with a slot or a hole that cooperates with the blade. When the lock core is not inserted with a key that matches it, the lock core and the lock core sleeve are linked together. A driving plate and a latch are also provided on the lock body, and the driving plate is connected with the latch. The rotating shaft comprises a connecting part, a transmission part and a driving part in sequence. The connecting part and the driving part are coaxially arranged, the transmission part and the driving part are eccentrically arranged, the connecting part and the lock core are circumferentially linked and connected, and the driving part is connected with the rotor switch. When the rotating shaft rotates, the transmission part can drive the driving plate to move to realize the telescopic movement of the latch. A wire pull slider is slidably arranged at the corresponding connecting part of the lock body, and a shift block is provided on the connecting part for driving the wire pull slider to move when the rotating shaft rotates. A first spring for driving the wire pull slider to reset is provided on the lock body.

[0004] The above-mentioned small ignition switch lock has the following problems in actual use: 1. Some motorcycles have a front toolbox lock and one of the seat lock or the fuel tank lock. However, the pull wire slider provided in the ignition lock switch can only be installed to open one of the locks, and cannot take into account multiple locks, so the practicality is poor; 2. When the ignition switch lock is turned to the lock head position, the lock bolt extends into the lock hole to lock the vehicle. At this time, if the car thief swings the handlebar violently, the front of the vehicle may shake, causing the shaft to break and the vehicle to be stolen, so the safety performance is poor.
