Definitions
- the present invention relates to an operating device for a bottom bracket drive with one or more actuating elements.
- the invention further relates to a method for controlling the bottom bracket drive and an electric bicycle.
- Known electric bicycles have control elements for controlling a drive, in particular for changing gears, which can be designed as push buttons, levers, trigger switches or the like.
- Derailleur gears are also known that carry out gear changes both mechanically, for example as a shift cable, and electrically, in particular wirelessly or wired.
- Other bicycle gear change systems are hub gears or gearboxes with switching devices. Shift levers, in particular trigger switches, or rotary switches are used to actuate the gears.
- Derailleur gears with trigger switches that are operated by the cyclist's thumb are the most common.
- Mode change switches are also known from the state of the art, with which, for example, an electric motor support can be selected, a push mode of the bicycle or the headlights can be activated or deactivated at the touch of a thumb.
- a remote control unit for the display unit of an electric bicycle is known.
- the remote control unit is arranged in the area of a handlebar grip away from the display unit and has support selection buttons for selecting the support level and at least one input device for menu navigation and selection of menu items displayed on the display unit.
- the input device and the assistance selection buttons are arranged along a convex arcuate common line with respect to the handlebar grip.
- the present invention is based on the object of proposing a more ergonomic operating device for a bottom bracket drive that is improved in terms of its operability.
- the task is solved by the subject matter Claims 1, 8 and 15. Further advantageous embodiments can be found in the dependent claims.
- the respective actuating element is a trigger switch, which can be actuated in two actuation directions, namely either in the first actuation direction or in a second actuation direction, by manual actuation by the cyclist or the user and depending on the actuation force from the neutral position.
- the respective actuating element returns to the starting or neutral position after each actuation.
- a spring mechanism or the like can be used for this purpose.
- each direction of actuation there are preferably two, alternatively three, four or more than four functional positions, one behind the other, which are separated from one another by the cyclist during actuation by means of pressure points.
- the user moves from the neutral position to the first functional position by actuating the respective actuating element with the first actuating force, which is smaller than the force required to overcome or cross the first pressure point.
- the user moves from the neutral position and/or the first functional position to the second functional position by applying a second actuation force that is necessary to overcome the first pressure point.
- a third actuation force is required such that a second pressure point, which noticeably separates the second and third functional positions from one another, is overcome.
- An actuation of the respective actuating element therefore occurs when the user of the electric bicycle exerts pressure on the respective actuating element with one of his fingers, in such a way that the actuating element deflects into the first or second actuation direction.
- the respective pressure point is a haptic feedback in the form of a perceptibly changed resistance during the actuation of the respective actuating element in the first or second actuation direction.
- first lever travel is required to reach the first functional position
- second lever travel that is further away from the neutral position compared to the first lever travel is required to reach the second functional position, which is achieved by overcoming a noticeable pressure point.
- Holding the respective actuating element at the respective lever travel can be realized by a suitable detent for fixing the respective actuating element in the respective functional position of the first or second actuation direction.
- the respective actuating element of the operating device can also be actuated in a path-dependent manner instead of a force-dependent actuation of the respective actuating element. If different actuation forces are mentioned in the context of this invention, different lever paths can also be used to control the bottom bracket drive by means of the respective actuating element.
- the respective actuating element is designed in the form of a rocker switch, wherein a first leg of the rocker switch can be actuated in the first actuation direction, and a second leg of the rocker switch, which is integrally connected to the first leg, can be actuated in the second actuation direction.
- the respective actuating element is alternatively designed as a switching lever.
- the shift lever can consist of two levers, buttons or switches that can be operated in the respective operating direction.
- the respective actuating element can be haptically recognized by the user of the electric bicycle while driving.
- the operating device is attached to the handlebars of the electric bicycle in such a way that the driver of the electric bicycle can operate the respective actuating element with at least one of his fingers, in particular his thumb, while ensuring at all times that he can hold the handlebar grip with both hands.
- the advantage of the operating device is essentially that through a simple combination of button assignment and assignment of the functional positions to the functions relating to the drive of the electric bicycle, it is also possible to set the functions relating to the drive of the electric bicycle while driving. This significantly increases driving safety, with the small number of buttons and a simple arrangement making intuitive operation of the operating device possible.
- the respective actuating element is therefore clearly arranged and designed.
- the at least one actuating element is a first actuating element, wherein the bottom bracket drive can be controlled or is controlled depending on an actuation of the first actuating element in such a way that the bottom bracket drive is gradually upshifted by one gear step by repeatedly actuating the first actuating element from the neutral position in the first functional position of the first actuation direction and immediately subsequent release of the first actuation element, and that a gradual downshifting of the bottom bracket drive by one gear step by repeatedly actuating the first actuation element from the neutral position into the first functional position of the second actuation direction and immediately subsequent release of the first Actuating element takes place.
- the first actuating element is therefore to be understood as a gear change switch that can be actuated in two actuating directions, each with at least two functional positions.
- Gradual upshifting or downshifting is therefore achieved by briefly tapping the first actuating element in the respective actuating direction from the neutral position to the first functional position, with each tap triggering a shift between two gears.
- Gradual upshifting or downshifting means that the gears are shifted up or down one after the other. Accordingly, tapping several times in the respective actuating direction from the neutral position to the first functional position causes sequential upshifting or downshifting.
- a drive power from a drive is transferred with a certain gear ratio to the output, i.e. the corresponding wheel of the electric bicycle.
- the first actuating element is released and returns from the respective functional position to the neutral position.
- the bottom bracket drive can be controlled or is controlled depending on an actuation of the first actuating element in such a way that the bottom bracket drive can be gradually upshifted by two or more gear steps by repeatedly actuating the first actuating element from the neutral position into the second functional position of the first actuating direction and immediately subsequently releasing the first actuating element, and that the bottom bracket drive is gradually downshifted by two or more gear steps by repeatedly actuating the first actuating element from the neutral position into the second functional position of the second actuation direction and immediately subsequent release of the first actuation element takes place.
- the first actuating element is actuated beyond the first pressure point up to the second functional position and accordingly moved in the respective actuation direction, a double or multiple switching takes place depending on the function assignment. It is advantageous if a double circuit is provided. For example, in a third functional position, a triple circuit can be provided when the first actuating element is actuated beyond the second pressure point up to the third functional position.
- the bottom bracket drive can be controlled or is controlled in such a way depending on an actuation of the first actuation element that an upshift of the bottom bracket drive by three or more gear steps takes place by actuating the first actuation element from the neutral position into the first functional position and/or second functional position of the first actuation direction and holding the first actuation element in the first or second functional position for a defined duration, and that a downshift of the bottom bracket drive by three or more gear steps takes place by actuating the first actuation element from the neutral position into the first functional position and/or second functional position of the second actuation direction and holding the first actuation element in the first or second functional position for a defined duration.
- Holding the respective actuating element in a specific functional position is understood to mean a long pressing or actuation of the respective actuating element, which carries out a specific switching function. In any case, holding the respective functional position lasts longer than the previously described tapping of the respective actuating element.
- a long press can, for example an actuation duration of greater than 500 ms, preferably greater than 1000 ms. The holding period that carries out the respective function can be freely selected and adjusted.
- a single shift can be carried out between two gears.
- an upshift can be carried out from a first gear in succession to a second, third, fourth gear, and so on.
- a downshift can be carried out, for example, from a fifth gear in succession to a fourth, third, second gear, and so on.

- the second actuating element is therefore to be understood as a mode change switch that can be operated in two actuating directions, each with at least two functional positions.
- setting, activating or deactivating the respective operating mode of the electric bicycle is done by briefly tapping the second actuating element in the respective actuating direction from the neutral position to the first functional position is reached, whereby each tap sends a corresponding input command to a control unit or the like, which can influence the operating modes of the electric bicycle or executes the function influencing the operating mode of the electric bicycle.
- the respective function influencing the operating mode of the electric bicycle is preferably a setting or selection of a defined drive support by an electrical machine which is effectively connected to the bottom bracket drive, the setting or selection of a recuperation level of the bottom bracket drive, the selection of a switching characteristic in the bottom bracket drive, the activation or deactivation of a pushing aid of the electric bicycle and/or the activation or deactivation of a headlight and/or a rear light of the electric bicycle.

- the bottom bracket drive 3 can be controlled depending on an actuation of the second actuating element 8 in such a way that a further function influencing an operating mode of the electric bicycle 2 can be set or activated by actuating the second actuating element 8 from the neutral position 13 into the first functional position 11 and/or the second functional position 12 of the first actuating direction 9 and holding the second actuating element 8 in the first functional position 11 or second functional position 12 for a defined duration, that the further function relating to the operating mode or the manner of use of the electric bicycle 2 can be set or deactivated by actuating the second actuating element 8 from the neutral position 13 into the first functional position 11 and/or the second functional position 12 of the second actuating direction 10 and holding the second actuating element 8 in the first functional position 11 or second functional position 12 for a defined duration.
- the second actuating element 8 is held in the first functional position 11 of the respective actuating direction 9, 10 for a certain period of time, for example, a headlight 17 and a rear light 18 of the electric bicycle 2 can be activated or switched on (first functional position 11 of the first actuating direction 9), or, if they are already switched on, switched off again (first functional position 11 of the second actuating direction 10).
- This command can be entered, for example, if the cyclist holds the second actuating element 8 in the first functional position 11 of the respective actuating direction 9, 10 for, for example, 1000 ms.
- a pushing aid or starting aid of the electric bicycle 2 can be activated or switched on (second functional position 12 of the first actuating direction 9), or if the sliding - or traction help is already switched on, can be switched off again (second functional position 12 of the second actuation direction 10).
- This command can be entered, for example, when the cyclist holds the second actuating element 8 in the second functional position 12 of the respective actuating direction 9, 10 for, for example, 1000 ms.
- Fig. 1 also shows a control unit 25.
- the control unit 25 is set up to communicate with an external device, here a smartphone 27 of the cyclist, wherein configurations of the operating device 1, in particular of the button and pressure point assignment, can be made using the smartphone 27.
- the functions and button assignments mentioned can be swapped around as desired. It is also conceivable that the required second actuation force to overcome the first pressure point can be adjusted.
- the holding time can be set for which the respective actuation element 7, 8 must be held in the respective functional position of the respective actuation direction 9, 10 until the input command is transmitted to the control unit 25 or until the control unit 25 carries out a corresponding control of the bottom bracket drive 3.
- the previous embodiments are intended to make it clear that by reducing the number of buttons and by clever arrangement, combination and button assignment, intuitive, almost blind operation of the control device 1 is possible.
- the actuating elements 7, 8 are arranged on the respective handlebar grip 5, 6 in such a way that the driver can operate them with the respective thumb without removing the respective hand from the handlebar grip 5, 6. It is conceivable that that both actuating elements 7, 8 are arranged next to each other on the left or right handlebar grip 5, 6 so that the bottom bracket drive 3 can be controlled with one hand alone.
