Description

Winding device, winding system and winding method based on at least two shafts Technical Field The invention belongs to the technology of winding long-strip objects, and particularly relates to a winding device, a winding system and a winding method based on at least two shafts, wherein the winding system is one of a tape measure, a telescopic charging wire, an expansion socket, an electric blower, a charging gun, a charging pile, a mobile power supply and a power supply adapter. Background Long objects such as ropes, wires, belts, chains, cables, films, tubes, optical fibers, etc. are usually wound around the outer periphery of a shaft when they are wound and stored in the related art. The shape after winding can be limited to a cylindrical shape, and finally the shape of a product can be limited to the cylindrical shape for design, so that the requirement of some application scenes can not be met. When the diameter of the shaft is small, the circumference of the shaft is also small, and the long object needs to be wound around the periphery of the shaft in a plurality of turns. When the diameter of the shaft is large, the circumference of the shaft increases as it increases, thereby reducing the number of windings, but it causes an increase in the volume of the product. Furthermore, when the elongated object is wound around the outer periphery of a shaft, the elongated object and the shaft are cylindrical, and the shape of the product is dependent on the cylindrical design, which also causes an increase in the volume of the product. Moreover, when the product shape cannot be rendered cylindrical, the product inner space cannot be sufficiently used for accommodating the elongated object, resulting in waste of the product inner space and increase of the product volume. Disclosure of Invention Aiming at the defects of waste of product space and increase of product volume caused by winding a long-strip object on the periphery of one shaft in the prior art, the invention provides a winding device, a winding system and a winding method based on at least two shafts, which aim to meet the requirements of more product application scenes to wind the long-strip object, so that the product has a compact structure and a small volume. To achieve the above object, a winding device based on at least two shafts of the present invention comprises: a support member; A winding mechanism disposed on the support member, the winding mechanism having at least two shafts; An annular band surrounding the at least two axes, the circumference of the annular band being L, the radius of the smallest diameter axis of the at least two axes being R, L >10.28R; a drive mechanism for driving the endless belt directly or via at least one shaft to move the endless belt around the at least two shafts; A long object fixed to an endless belt, the endless belt being driven by the driving mechanism to move around the at least two shafts, the long object being wound around an outer periphery of the endless belt; The annular belt is formed by encircling a part of the strip-shaped object or is an independent part mutually fixed with the strip-shaped object. The winding device surrounds the annular belt on at least two shafts, the positions of the at least two shafts can be arranged according to the space layout requirement of the product, the annular belt is not limited to be cylindrical any more, the shape of the annular belt can be determined according to the positions of the shafts, the inner space of the product can be fully utilized when a strip-shaped object is wound outside the annular belt, and the product is compact in structure and small in size. In addition, the part surrounded by the annular belt in the product can also be used for installing the internal structure of the product, so that the structure of the product tends to be more compact. According to the winding device, the circumference of the annular belt can be increased by increasing the distance between the shafts, the winding number of windings of a long object with a certain length can be reduced, and the lamination thickness of the long object after winding can be reduced. Or the length of the wound strip object may be increased when the number of turns of the wound strip object is the same. In a preferred embodiment, the drive mechanism is any one of a manual crank drive mechanism, a spring drive mechanism, and an electric drive mechanism. In a preferred embodiment, the spring drive mechanism comprises an elongated coil spring providing a spring force, the elongated coil spring being constrained within a receiving slot or over a rod. Because the diameter of the long-strip-shaped spiral spring is small, the long-strip-shaped spiral spring is easy to arrange according to the shape of a product, the volume and the space occupied by the long-strip-shaped spiral spring are reduced, and the product structure is compact. Moreover, the elongated coil spring is restrained in the rec
