Definitions

  • the present invention relates to a wheelchair combination with a Vorspannlenkvortechnische for a wheelchair with an electric drive means.
  • Wheelchairs for people with disabilities usually have two large, arranged in the forward direction rear drive wheels and two small, freely pivotable and forward in the forward direction arranged wheels, which are also called castors.
  • the drive wheels may be electrically driven or driven drive wheels and are then electric drive means of the wheelchair in the context of this invention.
  • Drive wheels known which are designed as an auxiliary drive device, both an electric drive motor and a gripping ring for manual drive and additionally comprise a sensor which detects a manually introduced into the gripping drive force, and a control device, the electric drive motor as a function of size and Direction of the manually introduced into the grip ring driving force and an adjustable level of support for delivering a corresponding torque drives.
  • Such auxiliary drive devices are also electric drive means of the wheelchair in the sense of this invention, but other drive means are also encompassed by this term.
  • the freely pivoting castors ensure a high level of maneuverability, which is indispensable especially in so-called indoor operation, ie when the wheelchair is used in closed rooms.
  • indoor operation that is when operating outside of closed rooms and especially on uneven roads
  • the small castors are disadvantageous and make even with relatively small bumps operation of the wheelchair impossible.
  • small front wheels would dip into depressions from which they could not come out because of their small diameter limited ability to negotiate an obstacle, which then makes driving impossible.
  • the DE 24 46 573 a pulling and guiding device which can be coupled to a wheelchair in such a way that, when coupled, the front small wheels of the wheelchair designed as freely pivotable castors are raised.
  • This known pulling and guiding device has a motor-driven wheel which can be steered via a steering rod.
  • the vehicle formed from such a coupled guide and the wheelchair is called a wheelchair team.
  • Comparable traction devices for wheelchairs and corresponding unicycle wheelchair compartment are for example from the GB 2 124 985 A from 1982, the DE 200 07 793 U1 from the year 2000 and the DE 10 2007 015 851 A1 known from 2007.
  • a disadvantage of this technical concept is that the wheel load and thus the contact pressure of the drive wheel of the traction device compared to the total operating mass of the unicycle wheelchair combination are low, since the majority of this total operating mass is introduced by the person sitting in the wheelchair whose focus in operation much closer to the rear large wheels is as the driven front Zugrad. As a result, only a small drive torque can be transmitted via the traction wheel and the traction wheel is already spinning at moderate inclines and moderate acceleration.
  • the DE 10 2012 109833 A1 shows a Vorspannlenkvortechnisch with pedal crank assembly and power assistance for a wheelchair.
  • the invention has for its object to provide an improved wheelchair combination with a Vorspannlenkvorraum, in particular to solve the technical problem set out above.
  • the biasing steering device according to the invention is designed so that the drive of the wheelchair combination according to the invention formed from the invention Vorspannlenkvortechnisch and a commercial wheelchair coupled thereto with at least one, preferably two electrically driven drive wheels, not only on the manually crankable by hand crank arrangement or driven steerable wheel of the biasing steering device takes place, but also via the electrically driven or driven drive wheels of the wheelchair, which are usually the large rear wheels of the wheelchair.
  • the biasing steering device according to the invention has for this purpose a Vorspannlenkvortechnisch control device which is adapted to an attached to the wheelchair electric drive means, that is, an electric drive means, for example electrically driven or driven rear wheels of the wheelchair to drive according to an introduced into the hand crank assembly force.
  • the electric drive wheels of the wheelchair that is, when the biasing steering device according to the invention is coupled to a wheelchair, which is formed from the Vorspannlenkvoriques and the coupled wheelchair wheelchair combination, depending on the amount and direction of the introduced into the hand crank assembly mechanical force is controlled and additionally driven by the rotation of the hand crank assembly, the steerable wheel of the biasing steering device.
  • a wheelchair combination formed from the Vorspannlenkvorraum and a wheelchair with two electrically driven wheels thus has three drive wheels.
  • the proportion with which the two driven wheels of the wheelchair participate in the overall propulsion of the wheelchair combination that is, the degree of support of the electric drive, can be variable and adjustable by the person sitting in the wheelchair person.
  • the biasing steering device has a hand crank assembly, which preferably also fulfills the function of a steering device, as is known from the DE 93 03 981.6 U1 is known, and uses an introduced in this crank assembly human force in connection with the control of the electric drive device of the wheelchair.
  • the introduced into the hand crank assembly human force leads to a certain speed of the hand crank assembly.
  • This rotational speed and the direction of rotation of the hand crank arrangement, but also a torque or a torque characteristic variable, for example the deformation of a component can be control variables in the control of the electric drive device of the wheelchair or serve to form control variables and / or contribute.
  • a wheelchair team can be formed from a commercially available indoor wheelchair and the preload steering device according to the invention, which has excellent driving characteristics.
  • This wheelchair combination gives the indoor wheelchair outdoor properties, makes the purchase of a separate outdoor wheelchair unnecessary, compared to the state of the art a much better Traction of the drive wheels and thus allows significantly better handling even on unpaved roads.
  • the steerable and driven by the hand crank assembly wheel can be made so large that it ensures the desired off-road capability, not already sinking into smaller wells so that from these can not be driven out, and even larger bumps such as coarse rubble or curbs can be overcome ,
  • the operation ensures, since only relatively large wheels, especially not the small castors, have ground contact, a good ride comfort.
  • the drive provided by the electrically driven wheels of the wheelchair ensures excellent traction, since the weight on the rear wheels portion of the total operating mass of the wheelchair combination consisting of the wheelchair, the Vorspannlenkvorraum and in person sitting in the wheelchair, is considerably larger than the proportion of the total operating mass of the wheelchair combination, which rests on the steerable and over the hand crank assembly drivable wheel of the biasing steering device.
  • the hand crank assembly provides the opportunity to maintain the valuable aspect of physical training while riding the wheelchair team by operating the hand crank assembly.
  • the propulsion of the wheelchair combination according to the invention consisting of a commercially available wheelchair and the preload steering device according to the invention, is supplemented by the additional contribution of the electrically driven rear wheels of the wheelchair.
  • this contribution can be variable, wherein the support of the propulsion of a wheelchair combination according to the invention, consisting of a commercially available wheelchair and the Vorspannlenkvorschaid invention, by the electric drive of the wheelchair, in particular by the electrically driven rear wheels of the wheelchair, can be adjustable.
  • the support can also take the form of an auxiliary drive device, as this example in the DE 198 57 786 A1 is described.
  • hand crank assembly sensors All of these sensors, which are required to detect the human force introduced into the hand crank assembly, are collectively referred to herein as hand crank assembly sensors, no matter where exactly they are located in one embodiment of the invention.
  • the signals of the hand crank locating sensors are fed to the biasing steering apparatus controller, processed there, and corresponding control signals are given to the electric drive means of the wheelchair, for example electrically driven or powered rear wheels of the wheelchair.
  • biasing steering device control means may cause activation of the electric drive devices mounted on the wheelchair both directly and independently depending on the embodiment, as well as in cooperation with corresponding motor control devices of the wheelchair.
  • the electric drive device of the wheelchair can be provided in a variety of ways.
  • a wheelchair which can be connected to the biasing steering device according to the invention for providing the wheelchair combination according to the invention, for example, both be designed as an electric wheelchair from the concept wheelchair as well as a manual in principle, the Does not mean electric motor driven wheelchair, which is only by replacing the purely manually driven wheels with such wheels, which are provided with an electric hub motor, to an electric motor driven wheelchair.
  • Such an electric motor driven drive wheel with a hub motor which can be mounted not only on a rigid running, but also on a folding wheelchair, is for example in the DE 41 27 257 A1 disclosed.
  • Another such electric motor driven drive wheel with a hub motor is for example in the DE 199 49 405 C1 disclosed.
  • All such drive wheels with hub motor including those as in the above DE 198 57 786 A1 described auxiliary drive device are drive wheels that make a wheelchair to an electric motor driven wheelchair in the context of the present invention, that is to a wheelchair with an electric drive device, which can be made by coupling the biasing steering device according to the invention to a wheelchair combination according to the invention.
  • An electronic control device for controlling the hub motors therefore has to cause an activation of both motors in the case of two drive wheels and thus two hub motors.
  • the Vorspannlenkvorraum control device of the biasing steering device according to the invention communicates in such a case with two engine control devices, namely each of a motor control device for a hub motor.
  • control or control of such electric drive wheels of a wheelchair in particular two types of control are known, namely a so-called torque control and a so-called speed control.
  • a torque control causes both motors to output the same drive torque.
  • Such a torque control is widespread especially in so-called brush motors. It has the consequence that both drive wheels, namely a left and a right drive wheel, build the same torque.
  • a one-sided disturbance occurs in such a torque control, in particular in the form of a one-sided obstacle, which is the case, for example, when one of the drive wheels travels over a rock or if it is driven on a transverse slope, then the same torque results on both sides the one-sided disturbance variable to a different speed.
  • the wheelchair would thus not go straight, but drive on a curve. Correction must be made by a modified move command.
  • a speed controller presets a specific setpoint speed, which follows the wheel rotation frequency. Disturbance variables of the type described above are thus already compensated in the way of this control. A corresponding controller increases the torque of the affected engine so that the target speed is maintained when a one-way obstacle occurs.
  • the manner of controlling the electric motors of the wheelchair with which the pretensioner steering apparatus can be connected to provide the wheelchair combination of the present invention can be accommodated.
  • a speed control has, when the Vorspannlenkvortechnische is coupled, with the consequence that the wheelchair combination tends to go straight regardless of the steering operation, since the drive wheels rotate on both sides with the same Radcardfrequenz while cornering the outer wheel opposite The inside wheel must have a greater wheel rotation frequency if slip is to be avoided.
  • Such a tendency to understeer the Wheelchair team can be countered by the fact that when coupling the Vorspannlenkvortechnisch to a wheelchair and this takes place the Vorspannlenkvortechnisch control device of the biasing steering device to a motor control device of the wheelchair, the operating mode of the motor control device of the wheelchair is changed from a speed control mode in a torque control mode Control of the drive wheels of the wheelchair thus no longer takes place as a speed control, but as torque control.
  • the motor control device of the wheelchair recognizes this as a new participant of the system when connecting the Vorspannlenkvor substances, for example via an RS-485 bus, and switches to the torque control mode.
  • the torque control then acts like an electric differential and allows without slip the speed differences arising during cornering between the inside of the curve and the outside of the curve.
  • Vorspannlenkvoriques and the wheelchair combination may be provided in the coupled state of the Vorspannlenkvorides on the wheelchair for the control of the drive wheels of the wheelchair speed control.
  • a speed mode of the controller may be selected, for example, when the preload steering apparatus is provided with a steering angle sensor that detects a steering angle and transmits corresponding signals to the preload steering apparatus controller such that, optionally in cooperation with one or more corresponding motor controls of the wheelchair , when cornering, the outside drive wheel is driven so that it rotates at a specifically higher rotational speed than the inside of the drive wheel. This allows a particularly good driving stability can be achieved.
  • an active engine brake may be provided, optionally in addition to one or more brakes acting externally on the wheels.
  • an operating device can be provided with one or more additional operating elements, which can be attached to the pretensioning steering device itself or, for example, laterally on the wheelchair.
  • the operating device may include a display device that displays information about speed, operating mode, state of charge of the batteries and the like, and it may include switches and controls, such as ON / OFF switch, operation mode switch, a stepless or stepped switch for setting a Degree of support and the like. In this case, variable or permanently preprogrammed degrees of support can be provided.
  • the variability of the degree of support can for example be used so that at the beginning of a ride, when the person sitting in the wheelchair team person is still fresh and rested, and / or if the low traction of the steerable and can be driven by the hand crank wheel of the biasing steering device unproblematic is, only a small, possibly reduced to zero degree of suppression by the electric drive wheels of the wheelchair is selected.
  • the capacity of the battery can be spared. If, after a certain travel time and distance, the forces of the person sitting in the wheelchair wear off, or if good traction of the driving wheels becomes more important, the degree of support can be increased. This allows you to continue driving even when tired.
