Definitions
- the invention relates to a device and a method for the electropneumatic adjustment of movable parts according to the preamble of the independent claims.
- Such devices are generally known, and they can be used particularly well in the motor vehicle sector for adjusting vehicle seats.
- adjustment options There are a number of adjustment options here, which are not only limited to an individual adjustment of the vehicle seat, but also allow an increase in seating comfort with regard to orthopedic aspects.
- a device for seat adjustment in which there is a combination of electromechanical adjustment and pneumatic adjustment.
- the device is driven by a universal motor, which either operates the pump and thus the pneumatic adjusting device via a gear, or drives the mechanical adjusting device.
- the pump requires a large, high-speed electric motor, because a correspondingly high pump output is required to actuate the pneumatic actuators. This requirement of high speeds is in conflict with the much lower speeds with which mechanical adjustment works optimally. Idling speeds of up to a maximum of 4000 revolutions per minute are desirable here. For pneumatic adjustment, pumps with speeds of typically around 7000 revolutions per minute are used.
- a tendon-running, large-sized pump not only has a relatively high weight, it also generates a lot of noise during operation.
- the main claim has the advantage that a pump with a significantly lower delivery rate can be used for adjusting movable parts, in particular parts of a motor vehicle seat, which allows the adjusting motor to optimally match the speed level in relation to the speed level Requirements of the mechanical adjustment device can be adapted.
- a pressure accumulator Through the interposition of a pressure accumulator, the motor that drives the pump belonging to a pneumatic adjusting device can be made much smaller, lighter and more compact. For example, an inexpensive standard motor can be used.
- the pressure accumulator can either be a large-volume low-pressure accumulator, e.g. be designed as an airbag integrated in the seat, but it can also be a small, compact high-pressure accumulator that requires very little installation space.
- the pressure accumulator is connected to a valve arrangement and to a pneumatic actuator arrangement which effects the adjustment.
- the fluid from the pressure accumulator can be specifically distributed to individual actuators, which in turn operate pneumatic adjustment levels.
- Such adjustment levels are, for example, a side support adjustment, the adjustment of a back support or a backrest adjustment. It is also conceivable that air cushions distributed over the seat are filled, which effect a contouring of the seat.
- Coupling is connected, with which either the mechanical adjusting device or the pump belonging to the pneumatic adjusting device can be operated. This gives you the option of using only one motor between the pneumatic and mechanical connections. Switching device to change. But it is also conceivable that the coupling only acts on the mechanical adjusting device and that the pump is depressurized when the mechanical adjusting device is in operation. This would relieve the motor in a similar way to explicitly decoupling the pump.
- a simultaneous drive of pneumatic and mechanical adjustment device can of course also be realized in this way, but is not necessary in view of the inventive concept.
- a control device is advantageous which is connected to at least one of the components engine, pressure accumulator, valve arrangement or mechanical adjusting device.
- This control device coordinates all processes that occur in the control of the device according to the invention.
- the connection to the pressure accumulator and the pump enables continuous monitoring of the pressure in the pressure accumulator and activation or deactivation of the pump if the pressure in the pressure accumulator is outside a desired range.
- the valve arrangement connected to it can be controlled, and thus targeted air pressure can be distributed to the individual actuators.
- the response and release of the clutch is another possible task of the control device in order to enable a change between the pump drive and the mechanical adjusting drive.
- the adjustment processes as such can be monitored and influenced.
- control device can record the pressure in the pressure accumulator, at least one sensor connected to the pressure accumulator is required, which transmits the measured actual pressure values to the control device.
- Settings of the various parts of the motor vehicle seat can be specifically influenced and individually adapted by a driver or a passenger of the vehicle.
- the following method for the electropneumatic adjustment of movable parts, in particular parts of a motor vehicle seat, can be carried out.
- a motor acts on a mechanical adjusting device and / or on a pump belonging to a pneumatic adjusting device. If the motor acts on the pump, a pressure accumulator is filled with a fluid to a predefinable pressure level. The pressure level of the fluid in the pressure medium is monitored and the pump is activated or deactivated when the pressure level falls below or exceeds the limits of a pressure interval. The pressure accumulator thus serves as a pneumatic energy reservoir and delivers this energy to the pneumatic adjustment device when required.
- a control device which detects the pressure in the pressure accumulator via at least one sensor and controls the pump as a function of this detected pressure value.
- the control is advantageously carried out in such a way that the pump is switched on when the actual pressure value drops below a predetermined or predeterminable lower pressure setpoint value, or that the pump is switched off when the measured te actual pressure value exceeds a predetermined or predeterminable upper pressure setpoint.
- this relatively simple control algorithm can be replaced by arbitrarily complicated control algorithms, which can also detect a leak in the pressure accumulator or at any point in the pneumatic system, for example, and switch off the pump after a certain safety time so that unnecessary operation is avoided.
- Another and essential part of the method is the activation of the motor and / or the clutch as a function of a signal which is output by an operating element to the control device.
- the control device can then activate the pneumatic adjustment device or the mechanical adjustment device or both adjustment devices, and then initiate a targeted adjustment.
- FIG. 1 shows an exemplary embodiment of an adjusting device
- FIG. 2 shows a block diagram which illustrates the principle of the method.
- FIG. 1 shows a device for adjusting movable parts, in particular parts of a device
- Motor vehicle seat consisting of a motor 10, a mechanical adjustment device 12 and a pneumatic adjustment device 14.
- the pneumatic adjustment device 14 has a pump 16 and a valve arrangement 18.
- the mechanical adjustment device 12 is composed of a
- the actuator 22 enables a helical toothed wheel 24, which is connected to a motor shaft 26, to be brought into engagement with a likewise helical toothed wheel 28, which is non-rotatably connected to the shaft 23.
- the motor 10 drives the shaft 23 when the clutch 20 is closed.
- the shaft 23 is connected to a schematically represented motor vehicle seat 30, whereby a longitudinal adjustment of the seat 30 is made possible. This longitudinal adjustment is indicated by the double arrow A.
- the motor 10 is also in constant communication with the pump 16, the pump 16 being depressurized when the clutch 20 is closed, so that the pumping of the
- the pump 16 is connected to a pressure accumulator 17 which receives the fluid conveyed by the pump 16 when it is not removed directly from the pneumatic adjusting device 14.
- this pressure accumulator 17 When the pump 16 driven by the motor 10 builds up pressure in the pressure accumulator 17 connected to it, then this pressure accumulator 17 is gradually filled and serves as a pneumatic energy reservoir.
- This pneumatic energy can be delivered via a valve arrangement 18 to various pneumatic actuators 32 distributed in the vehicle seat 30 and can be adapted and contoured accordingly on the vehicle seat.
- a control device 34 which performs various tasks. On the one hand, it is connected to the motor 10, the actuator 22 of the clutch 20 and the pump 16, and ensures that the motor 10 either drives the mechanical adjusting device 12 or the pump 16 of the pneumatic adjusting device 14 to build up pressure in the pressure accumulator 17. On the other hand, the control device 34 has the task of controlling the valve arrangement 18 and distributing the pneumatic energy to the individual actuators 32 of the vehicle seat 30. Another task of the control device 34 is to detect the pressure in the pressure accumulator 17 via a sensor 36 and to control the motor 10 and the pump 16 as a function thereof.
- control device 34 is connected to control elements 38. With these controls 38 a Driver or a passenger carry out the desired pneumatic and mechanical adjustments on vehicle seat 30.
- the claimed method according to FIG. 2 can be carried out with the exemplary embodiment shown in FIG.
- the control device 34 is connected to the motor 10, to the pump 16 and to the clutch 20. It can cause the mechanical adjustment device 12 to be actuated selectively by closing the clutch 20 or the pneumatic adjustment device 14 by emitting a corresponding signal to the pump 16. When the pneumatic adjusting device 14 is actuated, the motor 10 drives it
- the pneumatic energy building up in the pressure accumulator 17 can be specifically delivered to the pneumatic actuator arrangement 32 via the valve arrangement 18. This targeted and controlled delivery of the pneumatic energy is controlled by the control device 34.
- Another task of the control device 34 is to maintain the pressure in the pressure accumulator 17 within a predetermined or predeterminable interval.
- the pressure in the pressure accumulator 17 is detected by the pressure sensor 36 and passed on to the control device 34.
- This recorded actual pressure value is compared with two predefined or predefinable pressure setpoints. If this comparison shows that the detected actual pressure value is less than the minimum value specified or predeterminable in the control device 34, then the motor 10 and the pump 16 are activated, the detected actual pressure value is greater than a predetermined or predeterminable maximum value, then the motor 10 and the pump 16 is deactivated.
- This so-called two-point control ensures in a very simple manner that sufficient pneumatic energy is available in the pressure accumulator 17 at all times and that it does not have to be generated by a large and heavy pump within a correspondingly short time during the actual adjustment process.
- the control element 38 connected to the control device 34 enables a targeted influence on the adjustment of the seat.
- the regulation of the pressure in the pressure accumulator 17 includes a more complex control algorithm which, for example, makes it possible to regulate and maintain the pressure in the accumulator more precisely, or detects the respective pneumatic energy requirement and controls the pump 16 accordingly.
- Control methods are also conceivable that detect leaks in the pneumatic system and react accordingly, for example by closing certain valves or switching off the pump.
