When the connecting member 44 moves to the second position, the sliding member 64 can be linked to bias the second spring 62 and link the pin 74 to move to the retracted unlatched position.

The main body 12 of the present invention further includes a lower cover 96, and the lower cover 96 includes a hook 98. The lower cover 96 is installed on the lower side opening of the closed communicating groove 28 on the lower side of the main body 12, and is detachably connected to the engaging hole 36 of the main body 12 by a hook 98.

For the convenience of description, it is assumed that the connecting piece 44 is located in the second position (as shown in Figures 3 to 5), the convex portion 52 of the connecting piece 44 triggers the second detector 40, and the pin device 63 is located at the unlatched position. The plate end 65 of the 64 triggers the unlatching determination detector 42, so that the two-wheeled vehicle system (such as the trip computer) can determine that the bolt 74 is separated from the key hole 115 of the steering faucet shaft 113, and the rider can turn the steering faucet at will to change the two-wheeled vehicle’s travel. direction.

Assuming that the two-wheeled vehicle is at a standstill and the operation is locked, the driving gear 92 is operated by the driving device 90 to push the meshing gear row 50 to move the engaging member 44 from the second position to the first position. When the engaging member 44 is displaced to the second position After that, the convex portion 52 of the connecting piece 44 triggers the first detector 38 to stop the driving device 90. When the lock hole 115 of the quasi-steering faucet shaft 113 is aligned with the pin 74, the connecting piece 44 is displaced to the first position through the first spring 60 to press the sliding piece 64 together with the pin 74 from the unlatched position (third (As shown in Figure 5) position is displaced to the extended latch position, so that the mating end 76 of the pin 74 can be extended into the lock hole 115 to prevent the steering faucet shaft 113 from turning (as shown in Figure 8) to achieve the anti-theft function.

Assuming that the lock hole 115 is not completely aligned with the pin 74, when the connector 44 moves from the second position to the first position, the fitting end 76 of the pin 74 will be blocked by the peripheral surface of the steering faucet shaft 113 or the peripheral edge of the lock hole 115. Therefore, neither the pin 74 nor the sliding member 64 can move from the unlatched position to the latched position, so that the pin device 63 remains in the unlatched position but the connecting member 44 is displaced to the first position (as shown in Figures 6 and 7) ), and the displacement of the connecting piece 44 to the first position will compress the first spring 60 to store elastic energy (as shown in Figure 7), until the convex portion 52 of the connecting piece 44 triggers the first detector 38 to stop the driving device 90 operation (as shown in Figure 6), this design can avoid damage to the drive device 90. When the connector 44 is in the first position and the pin device 63 is in the unlatched position, turn the steering faucet shaft 113 to align the lock hole 115 with the pin 74 (the blocking condition is eliminated), and the elastic force of the first spring 60 pushes the slide The piece 64 and the pin 74 extend to the latching position (as shown in Figure 8), so that the fitting end 76 of the pin 74 is fitted into the lock hole 115 to lock the steering faucet shaft 113 so that it cannot rotate.

As shown in Figure 9, Figure 10 and Figure 11, it is assumed that the two-wheeled vehicle is in a stopped and locked state and is waiting to be unlocked. The driving device 90 is activated to push the meshing gear row 50 to move the engaging member 44 to the second position. When the latch 74 is not stuck, the connecting member 44 moves to the second position through the second spring 62 to push the sliding member 64 together with the latch 74 to move from the latched position to the unlatched position, so that the latch 74 can withdraw from the lock. The hole 115 unlocks the steering faucet shaft 113 and can be rotated. Assuming that the lock hole 115 is stuck to the pin 74 due to the deflection of the steering faucet shaft 113, so that the pin 74 will not be able to move, it will cause the pin device 63 to remain in the latched position but the connector 44 is moved independently from the first position to the second position and Compress the elastic energy of the second spring 62 (as shown in Fig. 10), and wait until the convex portion 52 of the connector 44 triggers the second detector 40 to stop the operation of the driving device 90 (as shown in Fig. 9). In this way, damage to the drive device 90 can be avoided. When the blocking condition is eliminated (such as shaking the faucet), the elastic force of the second spring 62 will push the sliding member 64 and the latch 74 to move from the latched position to the unlatched position (as shown in Figure 11). When the pin device 63 is in the unlatching position, the plate end 65 of the sliding member 64 triggers the unlatching determination detector 42, and the unlatching determination detector 42 sends out an unlatching determination signal, the unlatching determination signal It can be used with the start or power supply control of a two-wheeled vehicle. For example, the two-wheeled vehicle needs to be sure to receive an unlatching confirmation signal before it can start the engine, which can prevent the two-wheeled vehicle from starting the engine when the steering cannot be controlled.

The main switch lock 10 of the present invention is provided, which can compress the first spring 60 or the second spring 62 by the connecting member 44 when the latching pin 74 is stuck and cannot complete the latching or unlatching action during the latching or unlatching process. The energy is stored so that after the latching of the latch 74 is removed, the latch 74 can be quickly pushed to the latched position or the unlatched position with the return elastic force of the first spring 60 or the second spring 62.

In the present invention, the unlatching determining detector 42 can reliably detect whether the pin 74 is in the unlatching position, so that it can prevent the pin 74 from being jammed and unable to move to the unlatching position and the connector 44 is displaced to the first position or the pin 74 is jammed. The problem of misjudgment is caused by the displacement of the connecting member 44 to the second position and the displacement of the connecting member 44 to the second position.

The main switch lock 10 of the present invention is because of the arrangement of the first detector 38 and the second detector 40, if the pin 74 is obstructed and cannot be moved to the latching position or the unlatching position, it can still drive the device 90 to drive the connector 44. Displacement to the first position or the second position, that is, immediately stop the driving device 90, so as to avoid damage to the connecting piece driven by the driving device 90 due to excessive movement.

In the present invention, the combined structure of the waterproof cover 94 is sheathed on the periphery of the driving device 90, which forms complete protection for the electric driving device 90 to prevent two-wheeled vehicles such as motorcycles or electric locomotives from being damaged due to exposure to rain during outdoor operations.

It is worth mentioning that the present invention closes the communicating groove 28 through the lower cover 96, so when the pin device 63, the connecting piece 44, the first or second spring 60, 62 or the unlatching determination detector 42 needs maintenance, Maintenance and repairs can be performed quickly by removing only the lower cover 96.

The basic teachings of the present invention have been explained, and many extensions and changes will be obvious to those with ordinary skills in the field. For example, the lower cover 96 can not only be detachably inserted into the engaging hole 36 on the side of the connecting seat 20 with a hook 98, but the lower cover 96 can also be detachably screwed on the lower side of the connecting seat 20 directly with screws. .
