Definitions
- the present invention relates to an actuator for a side door of a motor vehicle, which causes the side door to open or close automatically as a function of a signal, with an electric motor controlled by the signal via a control device which, as a function thereof, has a gearbox a hinge of the side door generated acting torque, and a device for holding the side door in any open position.
- Motor vehicle doors that are not provided with an actuator are opened or closed by actuating the door handle and applying pressure against the door.
- the door In the open position, in addition to an end position, the door assumes certain holding (latching) positions in which the door movement is stopped and a corresponding resistance has to be overcome for further movement.
- the door opening and closing mechanism is provided with certain additional devices, such as brakes, blocking devices and the like. The arrangement of such devices is correspondingly complex.
- doors of motor vehicles which are provided with appropriate actuators.
- Such an actuator for a side door of a motor vehicle is described at the beginning. It causes the side door to be opened and closed automatically when the signal is activated by actuating the door handle, a push button on the dashboard or by radio control, etc.
- an electric motor of an actuator is controlled by the signal via a control device, which depending on this, a a gear generates torque acting on a hinge of the side door.
- the door is opened or closed in this way, it being possible for this to be carried out in any position, for example an end position or any intermediate position.
- a suitable sensor device can, for example, specify the door position to be reached.
- Even with such doors that are provided with an actuator it is known to generate certain stops to hold the door open, including, for example, additional braking devices, etc. are provided, which can be provided in addition to the actuator or within the actuator.
- the present invention is based on the object of creating an actuator of the type described in the introduction, which is characterized by a particularly simple and inexpensive design.
- an actuator of the specified type in that the holding device is implemented by a function of the electric motor itself, which is designed so that it has an increased cogging torque in the de-energized state, which is designed to a value that is Holding moment to hold the door open is required.
- Certain holding positions of the door can therefore be reached and maintained without special additional devices, such as braking devices, blocking devices, etc., having to be provided in the actuator or in addition to the actuator.
- the actuator designed according to the invention therefore has no additional device that fixes a holding position of the door, but the electric motor itself fixes this holding position in that the correspondingly increased detent torque must be overcome when the motor starts up again.
- the door can therefore not easily move further and, as in the prior art described at the beginning, assumes a latching position.
- the actuator designed according to the invention is attached to the vehicle body in the area of the door hinge and outputs the torque of its electric motor via a suitable gear to the door hinge to rotate it.
- a suitable gear to the door hinge to rotate it.
- a bolt in the door hinge is turned so that the door is opened or closed.
- the door is opened up to a maximum angle of, for example, 70 °.
- the electric motor of the door actuator is designed in such a way that when the motor is stopped, there is an increased detent torque which causes the door to remain in the corresponding holding position.
- the electric motor of the actuator is preferably designed as a brushless direct current motor.
- the air gap of the electric motor is designed to be particularly small.
- the electric motor has particularly few slots and poles.
- the actuator designed according to the invention can also have a sensor device that specifies certain holding positions of the side door. For example, if there is an object that hinders further opening of the door or prevents ver, the sensor gives a suitable signal to a control device that controls electric motor in a certain holding position, in which the door is held open due to the increased detent torque.
- the cogging torque of the electric motor is converted into a holding torque of the door in a desired position via the associated gear.
- the maximum torque in the de-energized state of the electric motor is converted into the corresponding holding torque for the door via the transmission.
- the transmission is therefore preferably designed in such a way that the corresponding cogging torque of the electric motor is increased and results in an increased holding torque.
- FIG. 1 shows an exemplary embodiment of an actuator which is installed in a motor vehicle
- FIG. 2 is a highly schematic side view of the actuator
- FIG. 3 shows a highly schematic plan view of the actuator in the closed position of the door
- FIG. 4 shows a highly schematic plan view of the actuator in the open state of the door
- FIG. 5 shows a highly schematic section through an electric motor of the actuator
- Figure 6 is a diagram showing the detent torque as a function of the angle of rotation.
- the embodiment described here is about an actuator for a side door of a motor vehicle, which, depending on a signal, generates a self- active opening or closing of the side door causes.
- the actuator has an electric motor controlled by the signal via a control device, which, as a function of the signal, generates a torque acting on a hinge of the side door via a gear.
- Figure 1 shows the actuator 1 installed on the A-pillar of a motor vehicle.
- Figure 2 shows the actuator 1 in a highly schematic side view.
- the actuator 1 has an electric motor (not specifically shown) which has an upwardly extending drive shaft 2 in the figure, which exerts a corresponding torque.
- the shaft 2 actuates a rotary arm 6 gela gela on a sliding element 3, which is fixed in a vehicle door.
- the corresponding mechanism is held by an arm 7 which is attached to the A-pillar of a motor vehicle, as shown at 4.
- a rotation of the motor shaft 2 thus causes the rotary arm 6 to pivot and thus the vehicle door to be opened or closed.
- FIGS. 3 and 4 each show a schematic plan view of the actuator 1 with a corresponding actuating mechanism (gear) for the vehicle door, FIG. 3 showing the arm 6 with the door closed and FIG. 4 showing the arm 6 with the door open.
- the actuator 1 shown and described here also has a device for folding the vehicle side door in any open position, which is implemented by a function of the electric motor itself.
- the electric motor is designed in such a way that it has an increased detent torque in the de-energized state, which is designed to a value that is required as the flip torque to keep the vehicle door open.
- the cogging torque of the motor is increased to the flolding torque via the gear mechanism provided.
- FIG. 5 shows a schematic partial section through an electric motor of the actuator 1.
- the motor has a rotor 9 and a stator 8, which are separated from one another by an air gap 10.
- a correspondingly small design of the air gap 10 generates a cogging torque of the electric motor which, if necessary through amplification via the associated gear, becomes a holding torque of the vehicle door, which is sufficient to hold the door open in a certain catch position.
- the diagram in FIG. 6 shows the cogging torque of the motor as a function of the angle of rotation, with a maximum cogging torque of 0.14 Nm being generated as the holding torque.
- the maximum detent torque of 0.14 Nm is multiplied by the transmission ratio of the associated gear of 375, so that a door holding torque of 52 Nm results.
- the torque required to open the door or to move the door further from a holding position is 62 Nm.
- the holding torque of 52 Nm generated by the detent torque and increased by the gear is therefore sufficient to keep the door open.
