Description

The present invention refers to a cable for anti-theft protection, electric charging and data communication for two-wheeled electric vehicles, in particular for pedal assisted bicycles, scooters or motorcycles.

For this type of two-wheeled vehicles, there are currently no solutions that allow the creation of multiple functions such as anti-theft, electric charging and data communication with the outside, which allow the electric charging of the vehicle to be carried out safely in a managed way.

Object of the present invention is solving the aforementioned prior art problems by providing a cable for anti-theft protection, electric charging and data communication for electric two-wheeled vehicles which allows to perform the following functions together:

• • ensure an electrical connection for charging the vehicle;
  • guarantee a connection for communication between the control unit on board the vehicle and the column of an external management and control system, or with the control unit itself, in autonomous anti-theft mode;
  • allow the alarm/anti-theft function via a guard wire; and
  • guarantee a mechanical anti-theft seal, of the metal chain type, by means of ropes present in the structure.

The above and other objects and advantages of the invention, as will emerge from the following description, are achieved with a cable for anti-theft protection, electric charging and data communication for two-wheeled electric vehicles such as that described in claim 1. Preferred embodiments and non-trivial variants of the present invention form the subject of the dependent claims.

It is understood that all attached claims form an integral part of the present description.

It will be immediately obvious that innumerable variations and modifications (for example relating to shape, dimensions, arrangements and parts with equivalent functionality) can be made to what is described without departing from the scope of the invention as appears from the attached claims.

The present invention will be better described by some preferred embodiments, provided by way of non-limiting example, with reference to the attached drawings, in which:

FIG. 1 illustrates a cut-away front view of a preferred embodiment of the cable of the present invention; and

FIG. 2 illustrates a cross-sectional view of the cable of FIG. 1.

With reference to the Figures, the cable 1 for anti-theft protection, electric charging and data communication for electric two-wheeled vehicles of the present invention substantially comprises:

• • an external containment sheath 13;
  • a spiral armor 11 contained in the outer sheath 13 and designed to ensure anti-theft mechanical seal;
  • a sheath 9 contained in the spiral armor 11; and
  • a group 7 of conductors 3 each wrapped in an insulating element 5, in which the group 7 is contained in the sheath 9, each of the conductors 3 being designed to perform one of the following functions (and the assembly of conductors 3 performing all the functions listed below):
  • electrical connection for charging a vehicle;
  • communication link between a vehicle and external control and management means (not shown); and
  • alarm/anti-theft function in case of its blanking.

In particular, the outer sheath 13 can be made of polyurethane.

Preferably, the spiral armor 11 comprises insulated galvanized steel cables.

Again in particular, the sheath 9 can be made of PVC.

As illustrated, the unit 7 is made as a composite joining of the conductors 3, so as to hold them integrally together.

Preferably, the insulating element 5 can be made of PVC type R2, while the conductors 3 can be made of flexible cord, preferably of annealed electrolytic red copper.

By way of example and not limiting, two-wheeled vehicles can be bicycles, scooters and motorcycles, but obviously the cable 1 of the invention can also be used for other types of vehicles with one, three or four wheels, which require the functions provided by the 1 cable itself.

The structure of the cable 1 described above is completed by the connectors 3 which can be found on one or both sides of the cable 1, constituting a real control, communication and anti-theft system in a single object.

The main technical characteristics of the cable 1 of the present invention are as follows.

The power supply and control cable 1 is armored, does not propagate fires, has a reduced emission of toxic/corrosive gases and opaque fumes in the event of a fire, is suitable for use in civil/industrial environments, in fixed laying even directly underground and unprotected. The armor guarantees optimal mechanical protection even in heavy-duty applications.
