Description

Folding structure and foldable vehicle Technical Field The invention belongs to the technical field of foldable vehicles, and particularly relates to a folding structure and a foldable vehicle. Background Folding vehicles (such as electric scooter and folding bicycle) have dual properties of short-distance riding instead of walking and portable storage, and are widely applied to urban commuting, shared traveling and multimode traffic connection scenes in recent years. In order to achieve structural rigidity of the body in an unfolded riding state and volume compression in a storage carrying state, a folding mechanism becomes a core functional component of the product. The existing folding mechanisms are divided into the following two types according to different triggering positions: 1) Front-mounted folding structure The operating mechanism with the structure is arranged on the front side of the vertical pipe, and a composite transmission scheme of the ejector rod and the connecting rod is generally adopted. When the folding bicycle is used, a user needs to manually pull the front handle, and the locking element is driven to act in a push mode of the ejector rod or in a connecting rod traction mode, so that locking and unlocking of the folding joint are realized, and the folding structure is mainly adopted by part of low-end bicycle types. However, the folding structure has the advantages of larger operation force required in the unlocking and locking process, particularly for female users, teenager users or high-frequency use scenes, laborious operation and poor experience, and in addition, the front layout enables the operation mechanism to be completely exposed to the front part of the vehicle body, so that the operation mechanism is easy to scrape and collide with surrounding objects in a folding state, and the appearance integrity is poor. 2) Rear folding structure In order to improve the operation feel and safety of the front structure, a folding scheme in which an operation mechanism is arranged at the rear side of the vertical pipe is developed later. This type of beta structure is for preventing that the latch fitting from taking place the mistake unblock in vibration or unexpected collision riding, and current scheme generally adopts the mode of addding the second safety lock. The safety lock is usually additionally assembled on the frame riser in the form of an independent lock tongue, a poking button or a clamping hook, so that the number of parts of the whole mechanism is increased, the assembly process is complicated, and the material cost and the manufacturing cost are synchronously increased. Based on the above, the present invention provides a novel folding structure and a foldable vehicle, so as to overcome the above-mentioned drawbacks. Disclosure of Invention The invention aims to provide a folding structure, which is simple in structure, and the rotation action of a trigger assembly can be accurately converted into the directional movement of a locking block through a transmission mechanism, so that the locking and unlocking switching of the locking block can be realized, and the operation is simple and convenient. The invention adopts the following technical scheme that the folding structure comprises: An upper connecting piece; The upper connecting piece and the lower connecting piece are oppositely arranged along the vertical direction, the upper connecting piece and the lower connecting piece are in butt joint fit to form an accommodating space, and the upper connecting piece and the lower connecting piece are rotatably connected through a hinge shaft; the locking structure comprises a locking block which is movably arranged in the accommodating space; the trigger assembly is rotatably arranged on the hinge shaft and is in driving connection with the locking block; when the trigger assembly is operated to rotate around the hinge shaft, the locking block can be driven to move in the accommodating space so as to switch between a locking position and an unlocking position, the locking block locks the upper connecting piece and the lower connecting piece relatively in the locking position, and the upper connecting piece and the lower connecting piece can rotate relatively in the unlocking position. Further, the trigger assembly includes: The handle is provided with a hinge part and a handle part, wherein the hinge part is provided with an eccentric hole and is hinged with the upper connecting piece and the lower connecting piece through a hinge shaft penetrating through the eccentric hole; one end of the connecting rod is connected with the locking block, and the other end extends towards the handle and is provided with a limiting structure; the adjusting block is sleeved on the connecting rod in a sliding manner and can slide along the length direction of the connecting rod; One end of each connecting piece is sleeved at two ends of the hinging part of the handle, and the other end of
