Description

Technical Field

[0001] This utility model relates to scooters, and more particularly to folding electric scooters. Background Technology

[0002] Folding electric scooters have a wide range of uses, covering various scenarios such as daily commuting, leisure and entertainment, and campus travel. Because their size is significantly reduced when folded, they are not only easy to pack and transport when sold, but can also be easily stored in a car trunk for transport in daily life.

[0003] For example, the patent application number 201810281255.8 discloses a folding scooter, which uses a pin to lock the folded and unfolded parts. This type of electric scooter has two disadvantages: 1. Only the steering column is folded, which cannot maximize the reduction of volume; 2. The folding structure is relatively simple and cannot guarantee the stability of the unfolded position, especially the folded position of the column, because instability in this position will affect driving safety. Utility Model Content

[0004] In view of the shortcomings of existing technologies, such as the inability to fold to the maximum extent and the instability of the unfolded folding structure, this utility model provides a folding electric scooter.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A folding electric scooter includes a pedal assembly, a front wheel assembly that is horizontally rotatable and located in front of the pedal assembly, a rear wheel assembly that is vertically rotatable and located at the rear of the pedal assembly, and a steering assembly. The steering assembly is vertically rotatable and detachably mounted on the front wheel assembly. The rear wheel assembly and the pedal assembly are provided with limiting structures for limiting the rotation of the rear wheel assembly. When folding, the rear wheel assembly is rotated upward first, then the front wheel assembly is rotated, and finally the steering assembly is folded so that the folding steering assembly and the rear wheel assembly are misaligned and located above the pedal assembly.

[0007] Preferably, the steering assembly and the front wheel assembly are vertically rotatably connected by a detachable hinge shaft that runs through both, and a locking structure is provided between the steering assembly and the front wheel assembly to lock them together.

[0008] Preferably, both the steering assembly and the front wheel assembly are provided with hinge shaft holes. The hinge shaft passes through the hinge shaft hole and extends out of the hinge shaft hole. One end of the hinge shaft is provided with a limiting head, and the other end of the hinge shaft is provided with a spring pin. After the spring pin extends, it and the limiting head limit both ends of the hinge shaft to prevent the hinge shaft from sliding along the hinge shaft hole and falling off. When disassembling, first unlock the locking structure, then press the spring pin and pull out the hinge shaft from the limiting head side.

[0009] Preferably, the locking structure includes a first locking structure, which includes a pin hole on the steering assembly, a sliding pin slidably disposed in the pin hole and subjected to elastic force by a spring, and a limiting hole on the front wheel assembly. When the steering assembly rotates to the point where the sliding pin and the limiting hole are aligned, the sliding pin extends into the limiting hole under the action of the spring force to lock the steering assembly.

[0010] Preferably, the pin hole has a through hole on its side and a limiting bolt is provided at the through hole. The sliding pin sidewall has a strip groove, and the end of the limiting bolt extends into the strip groove to limit the sliding stroke of the sliding pin. There may be one or two sliding pins. When there is one sliding pin, the pin hole is a blind hole and both the spring and the sliding pin are located in the blind hole. When there are two sliding pins, the spring is located between the two sliding pins, and a limiting bolt is provided at each of the two sliding pins.

[0011] Preferably, a pressing element is slidably provided at the limiting hole. When the pressing element is pressed inward, the inner end of the pressing element squeezes the sliding pin to unlock it.

[0012] Preferably, a bolt is provided on the side wall of the limiting hole, and a straight groove is provided on the side wall of the pressing part, with the end of the bolt extending into the straight groove to limit the sliding stroke of the pressing part.

[0013] Preferably, the locking structure includes a second locking structure, which includes a latching seat hinged to the front wheel assembly and a locking hook disposed on the steering assembly. The latching seat has a locking hook slidably disposed inside by a spring. When the locking hook on the latching seat is engaged with the latch, the spring applies a spring force to the locking hook so that the locking hook is always engaged with the latch.

[0014] Preferably, the side of the fastening seat is also provided with a sliding unlocking button supported by a spring. The unlocking button is connected to the lock hook inside. After the unlocking button is unlocked, the spring applies a restoring force to it.

[0015] Preferably, a limit shaft is rotatably provided on the steering assembly, and a torsion spring is provided between the limit shaft and the steering assembly to reset the limit shaft. A limit screw perpendicular to the limit shaft is provided on the limit shaft with an upper thread connection. A spherical receiving groove is provided on the fastening seat to accommodate the spherical head of the limit screw. After the fastening seat is fastened, the spherical head of the limit screw is located in the receiving groove and presses the fastening seat against it.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This application sets the folding structure of the steering assembly on the horizontal rotating part. When folding, the steering assembly is rotated first and then folded, so that the rear wheel assembly and the steering assembly can be folded in a staggered manner above the pedal assembly, maximizing the reduction of the volume after folding. In addition, the steering assembly is double-locked by setting two sets of locking mechanisms, and the two sets of locking mechanisms have the advantages of easy disassembly and folding. Furthermore, by setting an adjustable limit screw against the receiving groove, the fastening seat is pressed tightly to avoid shaking, thereby improving the stability after locking.
