Description

Folding locking structure for electric scooter

Technical Field

The utility model relates to an electric scooter accessory, specific is a folding locking structure for electric scooter.

Background

The electric scooter is a novel portable vehicle, has the characteristics of energy conservation and environmental protection, and is convenient and safe to use. Because the scooter has numerous advantages, make it more and more receive people's liking. In order to facilitate the storage and carrying, the scooter is designed into a foldable structure in many ways so as to reduce the size of the scooter and facilitate the storage and carrying. At present, a large number of folding scooters are available, the smaller folding ratio of the scooter is difficult to realize the carrying convenience in the true sense, and the folding structure of the scooter is complex. Finally, if the folder on the market is not locked externally, the gap between the bicycle head and the bicycle body is large, and the phenomena of large shaking and loosening after locking and riding can be caused.

This is also the technical problem that present electric scooter folding is urgently needed to be solved.

We have searched with the search formula "electric scooter and locking structure and folding", retrieve 47 patent documents altogether, through the screening, confirm that the patent right is for Nibo Rui Shi science and technology limited, the chinese utility model patent of application number 201821622298.X is the most close contrast file, this patent discloses foldable electric scooter's scray structure, including setting up the scray body in the electric scooter pole setting, the scray body include lower base member, the last movable part of connecting through the pivot that sets up in the side, the pivot on overlap and be equipped with rotatory handle, the side of rotatory handle extend and connect the pillar through the loose axle, rotatory handle press down around the pivot and will drive the pillar and stretch out the joint movable part, rotatory handle revolve the pivot and will drive the pillar and retract and go up the movable part separation.

For the sake of economy, only the exclusive right is extracted here, and this patent solves the problem of the expansion ratio of the folding structure mentioned in the background art, and to a certain extent, the folding of the electric scooter is really realized, but the following problems exist in this patent: 1. the clamping and the separation of the upper movable piece and the lower base piece are controlled by the knob, the precision requirement of the fit clearance between the knob and the rotating shaft and between the knob and the mounting pieces on the two sides is extremely high, and the fit clearance can change along with the increase of the use times, so that the knob fails, and the used materials are required to have extremely high stability and high cost; 2. the matching requirements among the resisting column, the resisting block and the clamping hole are high, and the processing difficulty is high; 3. in order to connect folding two parts, set up installation piece, adjusting bolt, and the installation piece sets up at last inside moving the piece, and adjusting bolt sets up at the oblique notch of last piece, and the installation degree of difficulty is big, waste time and energy. Based on the above three points, the patent does not have implementation conditions.
