Description

Bicycle parking lifting structure

Technical Field

The utility model relates to an improved parking column structure, in particular to a lifting structure for parking a bicycle.

Background

The bicycle is an environment-friendly and green transportation means, such as public bicycles widely arranged in cities and capable of complementing the defect of the last road required by mass transportation wheels. For convenience in management, structures such as an unspecified number of parking columns are generally arranged at proper places for parking public bicycles.

Referring to fig. 1, the parking pillar structure has a pillar body (not shown), a lock portion 1 disposed on the pillar body, and a wheel guide portion (not shown) disposed adjacent to the pillar body, wherein the lock portion 1 has a locking groove 1A and a guide surface 1B connected to the locking groove 1A. In contrast, when the public bicycle is parked (e.g., returned to a car), the public bicycle needs to be close to the parking post, the rider aligns or aligns the public bicycle's plug-in part 2 with the guide surface 1B of the parking post, and pushes the public bicycle's plug-in part 2 along the guide surface 1B into the locking slot 1A of the parking post to complete parking.

Before the plug 2 completely enters the locking slot 1A, the plug 2 will contact the guide surface 1B, and the guide surface 1B is in an upward slope structure, so that to move the plug 2 along the guide surface 1B, the rider needs to provide a considerable sliding pushing force 3 to push the public bicycle to drive the plug 2, so that the plug 2 can move along the direction 4 of the guide surface 1B.

Moreover, the sliding-up thrust 3 will cause the insert 2 to contact the guide surface 1B, so that the insert 2 and the guide surface 1B will generate a considerable frictional resistance due to the sliding-up thrust 3 being applied to the contact surface between the two objects, and the existence of the frictional resistance will counteract part of the sliding-up thrust 3, so that the insert 2 is more difficult to move.

Therefore, when the rider wants to park, the sliding thrust 3 to be provided must be increased, so that the difficulty of returning the vehicle (i.e. more effort) is increased, and the insert 2 is not easily pushed to be positioned, which results in the problems of mechanism abrasion or unreliable returning of the vehicle.

In more detail, one end of the lifting spring 50 is fixed to the guiding block 41, while the other end of the lifting spring 50, which is not fixed to the guiding block 41, extends into the guiding groove 42 (i.e. in a direction away from the inlet end 421) and forms a gradually lifting structure, and the other end of the lifting spring 50 is a gradually increasing slope structure, i.e. a gradually increasing lifting slope along with the distance from the inlet end 421. In one embodiment, the lifting spring 50 has a bending portion 501, and the bending portion 501 is disposed at the other end not combined with the wheel guiding portion 40, and is bent downward in a reverse direction at the highest point of the lifting slope and suspended (as shown in fig. 4A), when the lifting spring 50 bears weight, the bending portion 501 can act as a buffer with the substrate 60 (or the ground), so as to avoid deformation failure caused by excessive compression of the lifting spring 50.
