Embodiment Construction

[0029] exist figure 1 A drive unit 10 is schematically shown in FIG. 2 , which comprises a housing 20 . The drive unit 10 also includes parts of the electric motor 30 , the transmission 40 and the pedal drive 50 which are respectively arranged in the housing. The drive unit 10 comprises a locking mechanism comprising an electric actuator 60 and a locking element 62 driven thereby. An alternative locking mechanism is shown in dashed lines and comprises an electric actuator 60' or 60'' and a locking element 62' or 62'' driven thereby, respectively.

[0030] The locking element 62 can be engaged with the components of the transmission 40 by the actuator 60, the locking element 62' can be engaged with the components of the motor 30 by the actuator 60', and the locking element 62' can be driven with the pedal by the actuator 60' part of the component mesh. These components are the ones that turn when necessary when the electric bicycle is driven or driven. The pedal bearing ca...

Abstract

A drive unit is configured to drive an electric bicycle, having an electric machine, a transmission and a casing which completely encloses the electric machine and the transmission, characterized in that the drive unit comprises a locking mechanism which is also completely enclosed by the casing, wherein the locking mechanism comprises an electric actuator and a locking element which is connected thereto, is driven by the actuator and is configured to be placed in engagement with a component of the electric machine or of the transmission and in this way to lock the latter. A method for locking a drive unit of an electric bicycle, wherein the drive unit is accommodated in a casing which completely surrounds the latter, when a closing signal is received a locking mechanism, which is also accommodated in the casing, a locking mechanism locking element, driven by an actuator of the locking mechanism is placed in engagement with a component of an electric machine or of a transmission, and said component is part of the drive unit and is releasably locked by the locking mechanism which is engaged therewith.

Description

Background technique [0001] In the field of the invention relating to the drive-away locking of electric bicycles or also other electrically operated two-wheeled vehicles, such as electric scooters, external mechanical locking mechanisms are known, with which they are mechanically connected to a fixed object Or secure the e-bike by mechanically locking the wheel assembly. However, since the mechanical locking element is accessible from the outside, there is no protection against manipulation. [0002] Furthermore, for electric bicycles it is known to take advantage of mechanisms which cannot be driven electrically, see Internet page www.my-ebike.de / sparta.php , which describes the electric bicycle Nibur-Sparta ION. Despite the lock, the electric bicycle can, for example, still be taken away or simply used without electric drive. Methods are also known in which the electric motor is electrically short-circuited in order to ensure drive-away protection in this way. [0003] ...
