Embodiment Construction
[0026] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention rather than to limit the present invention, and, in the case of no conflict, the embodiments in the present invention Features can be combined with each other.
[0027] Such as Figure 1-Figure 8 As shown, the present invention provides a three-stage interlocking mechanism, comprising a rear fixed frame 55, a vehicle beam, and a front fixed frame 54 connected in sequence; the vehicle beam includes a first vehicle beam 561 and a second vehicle beam 562; Three-level chain institutions include:
[0028] The first locking assembly 51: arranged between the rear fixed frame 55 and the first vehicle beam 561, used to lock the connection state of the first vehicle beam 561 a...

The invention provides a folding electric vehicle and a three-stage interlocking mechanism thereof. The three-stage interlocking mechanism comprises a rear fixing frame, a vehicle beam and a front fixing frame which are connected in sequence. The vehicle beam comprises a first vehicle beam and a second vehicle beam; the three-stage interlocking mechanism comprises a first locking assembly, a second locking assembly and a third locking assembly. When the rear fixing frame, the bicycle beam and the front fixing frame are folded, firstly, the first locking assembly is unlocked, so that the rear fixing frame and the first bicycle beam can be folded, and after the rear fixing frame and the first bicycle beam are folded, the locking effect of the second locking assembly can be relieved, so that the first bicycle beam and the second bicycle beam can be folded; after the first bicycle beam and the second bicycle beam can be folded, the locking effect of the third locking assembly can be relieved, so that the second bicycle beam and the front fixing frame can be folded and buckled with each other, the situation that the rear fixing frame, the bicycle beam and the front fixing frame can be folded at the same time in the folding process, the folding operation difficulty is increased, and an electric bicycle owner is accidentally injured in the folding process is prevented.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicles, in particular to a folding electric vehicle and its three-stage interlocking mechanism. Background technique [0002] Two-wheeled electric vehicles are easy to drive, fast, labor-saving, and cost-effective. They are a convenient means of transportation for travel. Two-wheeled electric vehicles are small and light, suitable for driving on narrow roads and congested roads; thus, it can greatly improve the travel convenience of drivers. It can be taken out and ridden when riding. Most of the two-wheeled electric vehicles now have a folding function, which is convenient for the carrying and storage of the two-wheeled electric vehicles. Folding can be carried out at the same time, so that it is relatively difficult to fold and easy to accidentally injure the car owner. Contents of the invention [0003] The present invention provides a three-level interlocking m...
