At this time, the tilting mechanism 2 cannot tilt and swing relative to the supporting member 121; on the contrary, when the locked state (LOCK) of the tilting mechanism 2 is to be released, only the motor 81 and the locking action need to be rotated in the opposite direction. The pushing assembly 83 can be driven to rotate by the output gear 824 to generate reverse rotation. The pushing rod 831 is rotated by the threaded portion 8311 and the pushing member 832 to rotate the reverse axial force to make the pushing member 832 The piston 833 is no longer pushed, and the piston 833 no longer pushes the inner disc 842 at the same time, so that the outer disc 841 and the inner disc 842 of the locking caliper group 84 no longer apply to the disc. 7 Form a brake-type lock, and then the tilt mechanism 2 can be unlocked (UNLOCK), and the tilt mechanism 2 is sufficient The relative tilting swing relative to the supporting member 121 is restored.

As shown in Figures 1, 2, 3, 4, 5, 6, and 7, when the driver of the vehicle 1 wants to park temporarily (waiting for the traffic light) or for a longer period of time, he can use the control element 85 To start the motor 81 to drive the reduction gear transmission set 82 to rotate, the output gear 824 of the reduction gear transmission set 82 can drive the pushing rod 831 of the pushing assembly 83 to rotate to generate a rotating axial pushing force. The pushing rod 831 can use the axial force of the rotation generated by the threaded portion 8311 and the pushing member 832, so that the pushing member 832 pushes the piston 833, and the piston 833 pushes the inner piece 842 By this, the external make-up piece 841 and the internal make-up piece 842 of the locking caliper group 84 can form a brake-like lock on the disc 7, thereby enabling the tilt mechanism 2 to be in a locked state (LOCK), due to the The disc 7 oscillates synchronously with the tilting mechanism 2, so the disc 7 is locked by the external making plate 841 and the internal making plate 842 of the locking caliper group 84 of the locking unit 8 in a braking manner. Then, the tilt mechanism 2 cannot tilt and swing relative to the support member 121, and the tilt mechanism 2 can obtain a locked and stable positioning, so that the vehicle 1 can obtain a stable parking effect; on the contrary, when it is desired to release the When the tilt mechanism 2 is in the locked state, it is only necessary to make the motor 81 rotate in the opposite direction of the locking action, and the pushing assembly 83 can be driven to rotate by the output gear 824 to produce reverse rotation, so that the piston 833 no longer pushes the piston 833. The inner making piece 842, the inner making piece 842 can move a stroke away from the outer making piece 841, so that the outer making piece 841 and the inner making piece 842 of the locking caliper group 84 are no longer facing each other. The disc 7 forms a brake-type lock, and thus the tilt mechanism 2 can be released from the locked state.

The main effect of the present invention is that the vehicle 1 includes: a tilt mechanism 2 attached to the support member 121 at the front end of the frame unit 12; and the support member 1 is provided 21. The locking device A at the front.

The gear set 82 can further reduce the size of the locking unit 8.

The third effect of the present invention is that, as the locking unit 8 is located behind the disc 7 and in front of the supporting member 121, when viewed from a side view, the reduction gear set 82 of the locking unit 8 is located on the disc Between the sheet 7 and the supporting member 121; thereby, the space between the disc 7 and the supporting member 121 can be fully utilized, and the space in front of the vehicle 1 can be reduced, thereby avoiding the front portion of the vehicle 1 from being enlarged.

The fourth effect of the present invention is that the motor 81 is arranged on the upper side of the locking caliper group 84, and when viewed from a plan view, the motor 81 of the locking unit 8 and the locking caliper group 84 at least partially overlap; thereby The motor 81 can reduce the space between the left and right sides of the supporting member 121 and the upper cross bar 21 of the tilting mechanism 2, thereby avoiding the motor 81 from tilting the upper cross bar 21 of the tilting mechanism 2.

One end of the motor accommodating portion 861 is in communication with the reduction gear set accommodating portion 862. The reduction gear set accommodating portion 862 is covered with an outer cover 863, and the outer cover 863 is connected to the reduction gear set accommodating portion 862. An anti-leak gasket 864 is provided between them; the output shaft 811 of the motor 81 extends into the reduction gear set accommodating portion 862; thereby, the waterproofness of the locking unit 8 can be improved.

The eighth effect of the present invention is that the motor 81 is accommodated in the motor accommodating portion 861, and the bottom side of the motor accommodating portion 861 is provided with a bottom cover 865, the bottom cover 865 and the bottom of the motor 81 A shock absorber 866 is arranged between the sides; thereby, the cushioning effect of the motor 81 can be improved.

The ninth effect of the present invention is that the locking unit 8 is connected to the front and top of the supporting member 121 of the frame unit 12 by a connecting piece 1211; thereby, the setting of the locking unit 8 can be facilitated, and The space between the support member 121 and the tilt mechanism 2 is fully utilized.

The tenth effect of the present invention is that the pushing assembly 82 has a pushing rod 831, a pushing member 832 and a piston 833, one end of the pushing rod 831 is connected with the output gear 824; the pushing rod 831 has The threaded portion 8311 of the trapezoidal thread, the threaded portion 8311 of the pushing rod 831 is embedded in and engaged with the pushing member 832; thereby, the locking torque of the locking device A can be improved.

In summary, with the above structure, the present invention can indeed achieve the claimed purpose and effect, and has improved the effect compared to the habitual users, and it has obvious requirements for practicability, novelty and advancement. It is a patent for invention. For the application, I would like to ask your examiner for a detailed review, and I would like to grant you the approval of the patent.
