Definitions

  • This invention relates to a door mechanism and more particularly to a mechanism capable of moving a door and to a control method.
  • a door mechanism including a drive element and two electric motors which are driven together by a controller when the door needs to be moved.
  • the electric motors are driven simultaneously for moving the door.
  • the maximum speed of the door and the maximum torque available is dependent on what the electric motors together can provide.
  • the maximum torque is needed in predetermined situations which occur for a very short moment, when considering the entire time period during which the door is moved. This maximum torque needs, however, to be taken into consideration when selecting appropriate motors in order to ensure that the motors are dimensioned to be large enough.
  • An object of the present invention is to solve the above mentioned drawback and to provide a door mechanism with an improved energy efficiency and lower costs. This object is achieved with the door mechanism according to independent claim 1 and with the control method according to independent claim 11.
  • FIG. 1 illustrates an embodiment of a door mechanism 1.
  • the door mechanism is for a sliding door.
  • the door mechanism may be utilized also for other door types, such as for swing doors, for instance.
  • the door mechanism 1 comprises a drive element 2 which is movably arranged to extend between a primary pulley 3 and a secondary pulley 4.
  • the drive element 4 which in praxis may be implemented with an endless belt, such as a toothed belt, is connected by a bracket 7 to a door 5 for moving the door between a closed position 12 and an open position 13, as illustrated by arrow 6.
  • a primary motor 8 rotates the primary pulley 3 and moves the drive element 2 and simultaneously also the door 5.
  • a secondary motor 9 rotates the secondary pulley 4 and moves the drive element 2 and simultaneously also the door 5.
  • a controller 10 controls supply of electricity from a power supply 11 to the primary motor 8 and the secondary motor 9.
  • the electric supply to the primary motor 8 and the secondary motor 9 is implemented independently from each other. Mainly, electricity is supplied only to the primary motor 8 while the electric supply to the secondary motor is switched off. Typically, the electric supply to the secondary motor 9 is switched off while the door 5 moves with a constant speed or when the door 5 has reached a predetermined position. To maintain a constant speed, for instance, it is sufficient that only the primary motor 8 participates in driving the drive element 2 and in order to obtain a good energy efficiency it is advantageous to switch off electric supply to the secondary motor 9 during these time periods.
  • the controller 10 controls supply of energy simultaneously to both the primary motor 8 and to the secondary motor 9. In this way, when needed, additional power and torque is available to obtain a fast acceleration of even a heavy door (more than 300 kg, for instance).
  • a predetermined speed which is an optimal speed for the door in question has been reached
  • the controller 10 switches off supply of electricity to the secondary motor 9 and continues supply of electricity to the primary motor 8 only.
  • supply of electricity to the secondary motor 9 can be switched off once the door 5 has reached a predetermined position, for instance.
  • the motor controller 10 can be implemented with an AC drive output having a triple-H bridge powering 3 phases.
  • the motors driven by the controller can be AC synchronous motors or PMDC synchronous motors (Permanent Magnet DC motors).
  • the controller can drive the primary motor 8 and the secondary motor 9 with a second phase common to both motors.
  • the first and third phases can be connected via motor relays to one of the motors each.
  • the common second phase can be kept at about 50% duty cycle of the PWM (Pulse Width Modulation).
  • the first phase and third phase may be used in combination with the common second phase to drive both motors with active speed and torque control, enabling maximum motor torque.
  • the secondary motor 9 is switched off by disabling the phase (first or third) connected to it alone.
  • the rest of the movement is carried out by the primary motor 8 only by the common phase and the phase (the other one of the first or third) connected to it alone.
  • the motor controller 10 may be provided with a programmable part including a memory, a processor and control circuits, for instance, which facilitate for a user to store parameters and possibly software controlling the supply of electricity for the installation in question. Additionally the controller may handle door commands forwarded to the controller from one or more triggers or sensors arranged such that a user can trigger opening and/or closing of the door.
  • the combination of the secondary pulley 4 and the secondary motor 9 are dimensioned to provide a larger torque than the combination of the primary pulley 3 and the primary motor 8.
  • the primary motor can be used to ensure that a suitable speed range is covered for the door, while the secondary motor can be used to ensure that an appropriate torque range is provided.
  • Such a solution can be achieved by utilizing a secondary pulley 4 having a smaller diameter D2 than the diameter D1 of the primary pulley 3. In this way a larger torque is obtained from the combination of the secondary motor 9 and the secondary pulley 4, even though the properties of the secondary motor 9 would correspond to the properties of the primary motor 8.
  • Figure 2 illustrates the torque and speed during movement of the door 5 of Figure 1 .
  • line 14 illustrates the speed V of the door 5 at different moments of time t0 - t10 while the door moves between a closed position 12 and an open position 13, or vice versa.
  • Line 15 illustrates the available torque T to drive the drive element and the door at different moments of time.
  • a predetermined speed V has been reached.
  • the door may have reached a position from where further acceleration is unnecessary, or if needed, further acceleration can be achieved by means of the primary motor only.
  • the controller 10 switches off supply of electricity to the secondary motor 9, which can be seen in Figure 2 as a substantial reduction of the torque T illustrated by line 15.
  • the primary motor 8 alone is provided with electricity which is sufficient, as line 14 indicates that the speed still slightly increases after moment t1, and after that, the speed remains constant until reduction of speed occurs at the end of the movement of the door.
  • Figure 3 illustrates electric supply in the door mechanism of Figure 1 .
  • Figure 3 shows connection of two PMDC motors on a AC H-bridge, which together with two motor relays 16 and 17 may be integrated into the controller 10.
  • a first phase X and a second phase Y supply electricity to the primary motor 8.
  • the second phase Y and the third phase Z supply electricity to the secondary motor 9.
  • Two first motor relay 16 controls supply of the first phase X and of the second phase Y.
  • the second motor relay 17 controls supply of the third phase Z.
  • the controller 10 may select to supply both motors 8 and 9 with electricity, or alternatively, only the primary motor 8 with electricity.
