Abstract

A safety ignition switch with protective measures between gears includes a lock assembly, a base assembly, and a switch assembly. The lock assembly, base assembly, and switch assembly are connected by a connecting shaft. One side of the ignition lock is equipped with a double-ended pin and double-ended pin compression spring, and the other side of the ignition lock is equipped with a limit plate and limit plate spring. The turning of the key drives the corresponding rotation of the ignition lock cylinder and the ignition lock plate. When the gear is to be changed, the limit plate must contact a boss on the base, causing the limit plate to press downward along the limit plate spring to avoid the boss to complete the gear change. Therefore, manual operation and rotation and pressing actions are required to achieve gear changes, which improves the safety of switching between switch gears and effectively ensures the normal operation and performance of the vehicle.

DETAILED DESCRIPTION

[0020] Now combined Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 To further illustrate the present invention, a safety ignition switch with protective measures between gear positions includes a lock assembly, a base assembly, and a switch assembly. The lock assembly, base assembly, and switch assembly are connected by a connecting shaft 1. The lock assembly includes an ignition lock 2, an ignition lock cylinder 3, and a self-locking lever 4. The ignition lock cylinder 3 is provided with an ignition lock plate 31 adapted to the key. A double-headed pin 21 and a double-headed pin compression spring 22 are installed on one side of the ignition lock 2, and a limiting plate 23 and a limiting plate spring 24 are installed on the other side of the ignition lock 2. The limiting plate 23 includes an ignition position located on one side of the ignition lock 2 and a gear switching position in which the ignition lock 2 pushes the switch assembly to achieve gear switching by limiting the connection shaft 1. The base assembly comprises a base 5, through which the connecting shaft 1 passes. A boss 51, which surrounds the inner wall of the base 5 at its connection with the lock assembly, is provided. A notch is located in the center of the boss 51. A stopper 23 engages with the boss 51. The connecting shaft 1 forms a stopper at the connection between the base 5 and the lock assembly.

The stopper 23 includes an ignition position, where it engages with the boss 51, and a gear shift position, where the stopper 23 bypasses the boss 51 and enters the notch to engage the connecting shaft 1. The present invention drives the corresponding rotation of the ignition lock cylinder and ignition lock plate through the rotation of the key. To shift gears, the stopper must contact the boss on the base, forcing the stopper to press downward along the stopper spring, bypassing the boss to complete the gear shift. Therefore, gear shifting can only be achieved through manual operation and rotating and pressing actions, which improves the safety of shifting between switch gears and effectively ensures the normal driving operation and performance quality of the vehicle.
