Description

Technical Field

[0001] The present invention relates to an electric vehicle, and more particularly to a frame for a foldable electric vehicle. The present invention further relates to a frame lock for the frame of the foldable electric vehicle, wherein the frame lock of the frame of the foldable electric vehicle of the present invention is configured to keep the frame of the foldable electric vehicle of the present invention in an unfolded state when the foldable electric vehicle is in an unfolded state. Background Art

[0002] An electric vehicle refers to a vehicle that is driven by electricity or a power source to carry people and / or objects quickly. Common electric-powered electric vehicles, such as electric bicycles, electric scooters or electric vehicles, use electricity as a power source to drive themselves to move. Generally, a foldable electric vehicle refers to an electric vehicle or electric bicycle that can be folded to occupy a smaller space. Most foldable electric vehicles achieve foldability of the entire vehicle through their foldable frames to solve the defects of conventional electric vehicles that are large in size and inconvenient to carry.

[0003] A foldable electric vehicle that meets the requirements of users should have structural foldability, good safety and convenience of folding / unfolding operation. The good foldability of a foldable electric vehicle allows it to occupy a smaller space after being folded, making it easier for users to carry, transport and place. The good safety of a foldable electric vehicle requires that the foldable electric vehicle can provide users with stable support and ensure the safe driving of the foldable electric vehicle when in use (or unfolded). The convenience of the folding / unfolding operation of a foldable electric vehicle requires that the folding / unfolding steps of the foldable electric vehicle are simple and easy to implement. However, most of the existing foldable electric vehicles cannot take into account the structural foldability, good safety and ease of use. They either overemphasize the foldability and ease of use of the foldable electric vehicle, but do not pay enough attention to its structural stability in the use state; or overemphasize the foldability and structural stability of the foldable electric vehicle during use, but ignore the convenience of the folding and / or unfolding operation of the electric vehicle. Obviously, the former will bring danger to the user of the electric vehicle, especially the user in the riding state, while the latter, whether it is the folding of the electric vehicle or the cumbersome operation of the unfolding of the electric vehicle, will reduce the user's experience.

[0004] The Chinese invention patent with application number CN201610658603.X teaches a foldable electric vehicle, wherein the frame of the foldable electric vehicle can be folded and has a smaller volume after folding. In addition, the foldable electric vehicle taught by the patent keeps the folded frame in a folded state through a lock. However, the locking of the foldable electric vehicle by the lock of the patent is reversible, and the operating end of the lock is protrudingly arranged on the frame, which is easy to be accidentally touched and mislocked, bringing negative hidden dangers to the safe driving of the electric vehicle. Secondly, the lock of the foldable electric vehicle taught by the patent may fail to correctly lock the high and low ends of the rear frame of its frame together, and this incorrect operation of the lock will bring danger to the rider of the foldable electric vehicle. However, the foldable electric vehicle taught by the patent does not have any safety measures to prevent this. Summary of the invention
