Since the top block B4 has a convex edge, the convex edge contacts the baffle plate during the rotation of the clutch plate B6. Plate B5, so that the distance between the clutch shaft B62 fixed with the top block B4 and the baffle plate B5 begins to increase, so that the clutch shaft B62 starts to move to the left in the clutch plate B63, so that the distance between the shaft B3 and the clutch shaft B62 The distance is shortened, the clutch shaft B62 moves to the left along the moving groove B63, and the gears of the two also mesh with each other, so that the rotation of the pedal seat A3 can drive the rotation of the pull rod C3 and enter the meshing state. At this time, the user can step on it freely. Control the support wheel to put it down or put it up.

As shown in Figure 6 and Figure 7, when the pedal A1 is pushed forward so that the unlocking piece A5 is located in front of the lock hook A7, the entire pedal seat A3 is pressed down clockwise, so that the pedal seat A3 presses the locking piece A8 counterclockwise Rotate a small range, so that the lock piece A8 enters the lock hook A7, and reaches the locked state again under the action of the lock hook A7 torsion spring. At this time, the right end of the check piece A61 is located on the left side of the check block B61. When the clutch plate B6 counterclockwise When rotating, the non-return block B61 is blocked by the non-return piece A61, so that the clutch plate B6 cannot rotate, so as to achieve the locking of the clutch plate B6; it can ensure that when the clutch pedal is in the engaged and locked state, the contact between the two gears The meshing will not be disengaged, which is safer and more secure, so that the supporting wheels are always in a falling state without being retracted, and can be used for supporting or parking the battery car.

The advantage of this embodiment is that the driver can choose whether to use the driving assistance device according to his own preferences; if not, adjust the clutch pedal to the non-use state, and adjust the clutch pedal to the ready-to-use state if he wants to use it.

Secondly, since the non-return plate A61 has a limiting effect on the non-return block B61 when the engaged locking state and the non-use state are engaged, the clutch plate B6 is in a locked state when in use and not in use, and the clutch control is more stable and more stable. Safe (does not half-route engaged to disengaged).

The above description makes the preferred implementation of the present invention, for those skilled in the art, without departing from the principle of the present invention, some modifications and improvements can be made, which should also be regarded as the protection scope of the present invention.
