Description

The present invention relates to a mobile and stationary training station in the form of a bicycle.

Bicycles are widely used as means of transportation to promote fitness or as stationary training stations. The use of the bicycle as a mobile fitness device is often tied to the corresponding weather conditions, so that its use in rain, thunderstorms, storms, extreme cold, snow, icy roads, extreme heat, etc. is restricted, if not dangerous. Furthermore, it is generally not possible to follow a preselected training program with preselected and appropriately controlled loading parameters for the trainee's body.

From the DE 20 2014 103 740 U1 a mobile and stationary training station in the form of a bicycle is known. The training station shows an electric motor, an accumulator, a power generator, an electronic control unit with a memory function that controls the interaction of the electric motor, accumulator and power generator depending on a preselected training program and current load data, a display with an operating function for preselecting and displaying parameters of the training program and a stable stand that supports the bike on both sides.

The DE 20 2005 021 847 U1 shows a bicycle support with a base to be attached to a bicycle frame, on which two support legs are pivotally mounted, the support legs each having a pivot axis inclined relative to the horizontal, and at least one coupling element is provided, which is set up to influence the pivoting movement of a support leg to transfer each other support leg.

The EP 1 582 451 A 1 shows a motorized bicycle that includes means for storing the energy generated when pedaling the bicycle. Thus, with the motorized bicycle of the invention, it is possible to use and store for other purposes the energy that the user expends during the physical activity carried out on the bicycle itself.

The GB 2 485 216 A describes an electric pedal bicycle that includes an electrical control system and an assist mechanism, the control system being adapted to control the operation of the bicycle to implement a predetermined exercise program and to compensate for the terrain over which the bicycle may be ridden. The electrical control system may be configured to monitor values of one or more characteristics of a driver, including one or more physiological characteristics, and to control the assist mechanism according to the one or more monitored characteristics. The control system can also increase a driver's load through regenerative braking. In addition, the control system may control the assist mechanism in response to a direct measurement of an incline on which the bicycle is being ridden.

The object of the invention is to provide such a training station in which a preselected training program with preselected load parameters, including interval load parameters, in particular the pedal resistance, is independent of the path or road condition, in particular inclines, slopes, and also of weather conditions such as headwind or tailwind, can be maintained.

These and other objects of the invention are achieved by a mobile and stationary training station in the form of a bicycle, the bicycle having an electric motor, an accumulator, a power generator, an electronic control device with a memory function, which controls the interaction of the electric motor, accumulator and power generator depending on a preselected training program and current load data, a display with an operating function (human-machine interface, "MMS") for pre-selecting parameters of the training program and a stable stand with legs that can be extended or folded out on both sides of the bike.

A sensor detects whether the training device is jacked up on the stand for stationary operation and, if the stand is active, switches off the electric motor via the control unit. For safety reasons, a sensor is also provided which switches off the electric motor when the pedals are not moving.

Preferably, the speed of the bicycle can be changed during mobile operation by manual operation, preferably a rotary handle arranged on the handlebar, with the manual operation dominating the automatic speed control.

Preferably, in mobile operation, a desired training performance P can be selected via the MMS before the start, for example by specifying a virtual path gradient, and/or a desired driving speed v, which are stored in the control unit. The current training performance can be monitored via sensors that determine the pedal resistance PW and, if necessary, the rotation speed of the pedal axle can be measured, registered and compared with the preselected training performance in the control unit. The current driving speed can be compared with the preselected driving speed using sensors that measure the rotation speed of the wheels. Deviations from actual and target values can be automatically compensated for using the power of the electric motor controlled by the control unit. If the current power exceeds the target power when the electric motor has zero power, excess power is fed into the accumulator via the generator, for example when the road gradient is negative.

During stationary operation, i.e. when the bike is jacked up using the activated stand, any preselected speed is not taken into account. To compensate for the deviation between the target and actual power, the control unit controls the power consumption of the generator or by measuring the pedal resistance and the rotation speed of the pedals. The power control can be done by regulating the pedal resistance. The electrical energy generated by the generator is fed into the accumulator to charge it.

Preferably, the pedal axle can be decoupled from the axle of the drive wheel, e.g. the transmission can have an idle function that is automatically activated when the training device is jacked up. Particularly preferably, the mobile training station does not have a chain for transmitting the drive power from the pedal axle to the drive axle, the energy generated by the pedal rotation passing through electrical lines from the generator, which is arranged on the pedal axle, to the electric motor, which is on the axle of the driven Wheel is arranged, is transmitted. This has the advantage that during stationary operation, when the electric motor is switched off or idling is active, the drive wheel of the bicycle does not rotate, i.e. both wheels are in contact with the ground, so that a foldable stand without a complex stand is sufficient for stationary operation.

If the power generated by pedal rotation is not sufficient for the preselected target power or the preselected target speed, the control unit provides additional power from the accumulator or feeds excess power into it.

It is further preferred that the training station has an interface connected to the control device for feeding in physiological status data such as heart and breathing rate, electrical skin resistance, electrically measurable muscle activity and / or blood sugar values, in particular the heart rate, of the trainee. The trainee can wear corresponding sensors on their body, the measured values of which are transferred to the control unit, which are compared with physiological target data specified in the control unit, and which can be shown on the MMS display, so that in the event of a deviation from the preset physiological target Data can either automatically correct the actual performance or the trainee can make corrections to the target performance with automatic correction of the actual performance by changing the electric motor support. In particular, if the actual data exceeds a tolerance range of the target data, an automatic reduction of the target data can be provided, so that the actual data is automatically adjusted by increasing the electric motor support or, in stationary operation, a reduction in the pedal resistance.

The operating interface (MMS) is preferably designed as a touchscreen. Furthermore, a navigation system can be integrated that can be accessed via the touchscreen.

The invention is explained below by way of example using the attached figures:

• 1 shows schematically a training station according to the invention.
• 2 represents an embodiment of the logic of the control device.
• 3 represents preferred further logic steps.
• 4 shows an embodiment of an MMS display.

In 1 The reference number 1 generally designates the training device with supports 2 that can be folded out on both sides, the electric motor 3, the accumulator 4, the generator 5, the control unit 6, the display and operating unit (MMS) 7 and the rotary handle 8 for manual speed control.

In 2 Operations that can be carried out automatically by the control unit are shown with a double border. Simply outlined operations can be carried out by the trainee themselves. The decision-making steps of logic are marked with numbers in a circle. After switching on using On/Off, the exerciser is asked to select either a pre-stored training program or target performance data (P), in particular in the form of a desired virtual path gradient. The MMS then asks you to decide whether speed control is desired (1 - “v control?”). The trainee can then choose a target speed (“v-target specification”) and start the training program.

Control by the control device is now carried out by cyclically querying the status of the training station and the training data as well as their adjustment.

The safety query as to whether the pedals are being pressed (2 - “Pedals moved?”) leads to the electric motor being switched off if the answer is negative. Likewise, the second security query as to whether the legs of the stand (6 - “jacked up?”) are active.

The actual performance of the trainee is compared with the target performance (3 - “Compare actual P with target P”). If there is a deviation, the question can then be asked as to whether an adjustment (5 - “Adjust?”) is desired or whether an adjustment can be made automatically by changing the pedal resistance PW (“Adjustment PW”). If the support legs of the training device are not active, the control unit checks whether the automatic speed control is switched on (7 - “v control?”); If not, a check is made to see whether the hand speed control is active (8 - “v-hand control active?”), i.e. whether the rotary handle is being operated. If the hand control is active or the automatic speed control is switched off, the electric motor support is controlled based on the hand control. If the manual control is not active (8), the control compares the actual speed with the target speed (9 - “Compare actual v with target v”) and increases or reduces the support from the electric motor (“E-motor- P”) accordingly to adapt the actual speed to the setpoint.

It is preferably provided that the adaptation of the actual speed to the target speed does not take place too quickly, either by measuring and limiting the acceleration, by adapting according to predetermined time-staggered steps, or if the difference between v-actual and v-target is too large automatic adjustment is switched off.

The control cycle is shown on the left side of 2 closed for query 2. If the electric motor is switched off for safety reasons as described above, the control unit checks whether the training station has come to a standstill during mobile operation (10 - “E-bike stopped?”). The trainee can then decide whether he wants to end the program (11 - “End program?”). If so, the switch to switch off will only appear on the touchscreen after the answer, so that the control is not switched off accidentally. Before switching off, it can be provided that statistics about the completed training program are shown on the display.

3 shows additional steps of the logic that are included in the logic according to the double line labeled A 2 can be inserted if an interface is provided for feeding current physiological data from the trainee into the control unit. The control unit checks whether the current physiological data is within the tolerance range of the pre-stored physical data (11 - “Physical status within the framework?”) and, if the upper tolerance limit is exceeded, reduces the target pedal resistance PW or accordingly, thereby providing support the electric motor is increased.

4 shows an example of a display when the training device is in mobile operation. The top line shows the physiological data, such as the actual heart rate (132/min), the target heart rate (140/min) and the minimum and maximum measured heart rate (63 to 152/min) during the current training session. The target heart rate can be changed by touching the switching symbols + and -.

The middle line provides information about the actual speed, the distance traveled so far and the charge status of the battery (51% - range still 48 km).

The bottom line provides information about the set target speed (18 km/h) and the target pedal resistance (preselected travel gradient 5%). Touchscreen controls + and - are also provided for manually changing the setpoint values.
