Description

Technical Field

[0001] The utility model relates to the technical field of ignition switches, in particular to a locomotive ignition switch. Background Art

[0002] The ignition switch is usually used to control the power supply, seat lock, faucet lock, and fuel tank lock of an electric bicycle or motorcycle. The utility model patent with application number CN202323219043.2 discloses a double-wire intelligent motorcycle ignition switch. The lock body is slidably provided with a second wire pull seat at the driving part of the corresponding rotating shaft. The driving part is provided with a shift block for driving the second wire pull seat to move horizontally when the rotating shaft rotates. The lock body is provided with a second spring for driving the second wire pull seat to reset. A bracket is provided in the lock body, and the rotating shaft is passed through the bracket. The bracket is provided with a second slide groove for the second wire pull seat to slide horizontally. The lock body is provided with an opening for the wire to pass through at the second wire pull seat. The second wire pull seat is provided with a second boss. One end of the second spring is sleeved on the second boss, and the other end is against the side wall of the second slide groove.

[0003] In the above-mentioned dual-wire intelligent locomotive ignition switch, by arranging a second wire seat and a first wire seat on the lock body, two wires can be installed at the same time, which are used to open two of the seat cushion lock, fuel tank lock or front tool box lock. When the rotating shaft is rotated, the shift block is pressed against the second wire seat, driving the second wire seat to move toward the direction close to the second spring to realize the unlocking action. After the interference is removed, the second spring can drive the second wire seat to reset. In this structure, the wire head of the wire is fixed on the second wire seat. When unlocking, the second wire seat drives the wire body to move. The wire body is passed through the interior of the locomotive. Other lines or devices are distributed around the second wire. The wire body will be disturbed when it moves, affecting the smoothness of the wire unlocking. Summary of the Invention
