Definitions
- This invention relates to a door drive system, and more particularly to a door drive system for a sliding door for a vehicle.
- the invention results from the realization that a reliable, safe, long life, and lightweight door drive system can be effected using a rotary motor and pulleys to translate a belt connected to a drive arm for operating a sliding door between open and closed positions and the further realization that an equally effective door drive control system can be achieved by sensing the door position and controlling the torque, speed and acceleration of the door in the opening and closing modes and using an obstruction detecting device to interrupt motion of the door in closing modes upon the presence of an obstruction.
- This invention features a door drive system for a sliding door including a pair of pulleys, a drive belt on the pulleys, and a drive shaft engaged with the drive belt.
- a rotary motor for rotating the drive shaft to translate the drive belt

- There may be an upper rail and a lower rail and a pair of spaced linear bearings for riding on each of the rails and interconnecting with the upper and lower portion of a sliding door.
- There may be an electrically powered locking device for securing the sliding door in the closed position and a passive actuating device for releasing the locking device upon an electrical power failure.
- the invention also features a door drive control system for a sliding door including a door drive system having a motor for moving a sliding door between the open and closed positions, and a position sensor for sensing the position of the sliding door.
- a controller is responsive to the position sensor for setting the speed, torque and acceleration of the motor in the opening and closing modes.

- a vehicle 10 such as a personal rapid transit vehicle which operates in a guideway including a body or cab 12 and a door 14.
- a vehicle and guideway system are shown and discussed in more detail in the following copending U.S. patent applications, filed on even date herewith: "Lateral Suspension Assembly for a Guided Vehicle System", by David C. Collins, Albert E. Lewis, and Gerald A. Garneau, Jr.; "In- Vehicle Switch Mechanism” by David C. Collins, Albert E. Lewis, and Gerald A. Garneau; "Passive Steering Assembly for a Guided Vehicle", by Robin Hossfield, John Puhlhorn, David C.
- Door 14 slides forward and backward between the closed and open position in the general direction of arrows 17.
- a lower guide rail assembly 16 which includes lower guide rail 18 that is fixed to the vehicle body or cab 12.
- a second pair of upper spaced linear bearings 24 and 26 are mounted on the upper portion of door 14 and slide along upper guide rail 28 in the upper guide rail assembly 30.
- An elastomeric seal 32 extends along the front and top edge of door 14 to weather seal the door against cab 12.
- the seal is typically elastomeric and has contacts inside of it so that when seal 32 contacts an obstruction it collapses and closes its contacts and thereby provides a signal of the presence of an obstruction.
- Door 14 is driven in the closing and opening modes by a door drive arm 36 which attaches to the door at approximately its center of gravity CG so that the door moves smoothly without cocking or twisting.
- Door drive arm 36 is fixed to move with drive belt 38 which is driven by drive assembly 40 all of which is located in an equipment bay 42 covered by a plate, not shown.
- Drive assembly 40 includes a drive motor 50 and gear head 52. It also includes an encoder 54 which constantly monitors the position of door 14. Door 14 is shown in the closed position in full lines and the open position in phantom lines in Fig. 2. A fail safe door locking device 56 is used to lock door 14 in the closed position but release it automatically upon a failure of electrical power so that the door can be opened manually. Also located in bay or recess 42 is the lock sensor 58 and closed sensor 60 which are typically triple-redundant sensors.
- Door drive system 62 is shown in more detail in Fig. 3 where it can be seen that drive belt 38 is a toothed drive belt as represented by the teeth 64 which engage with similar teeth on splined drive shaft or tooth gear 66 around which the belt is directed and tensioned by an idler pulley 68 and eccentric belt tensioning pulley 70. There are idler pulleys at each end 72, 74.
- the obstruction detection device includes a number of different sensors. For example, as shown in Fig. 4, seal 32 which wraps around door 14, is hollow and contains contacts which when the seal is crushed or pressed come together and provide a signal that an obstruction is present. The side part of the seal 32a abuts a sealing surface 80 under the side wall and roof 82 of cab 12.
- the obstruction detecting device includes a second subsystem which typically uses an electromagnetic beam such as light, visible or invisible, or may even use ultrasonic or other acoustic waves to sense the presence of an object at the top of the door even before contact is made with the seal 32.
- a light curtain assembly 90 may include a light source such as infrared light source 92 mounted underneath roof 82 which creates a light curtain directed across to infrared sensor 94, also mounted under the roof 82. A person whose shoulder, arm or head rises up through the door opening 96 would interrupt the light curtain 98 between source 92 and sensor 94 and provide a signal indicating an obstruction is present even before the seal 32 touched the person.
- Seal 32 is a two-part elastomeric component including a base 100 which mounts to the door and a removable and replaceable snap-in portion 102 which actually performs the sealing action against the sealing surfaces of the cab. Within that portion is a recess or cavity 104 in which is located a contact plate 106 and a contact button 108. Any pressure on seal 32 such as indicated by arrow 110 begins to collapse the upper portion 102 and bring contact plate 106 into proximity and then engagement with contact button 108. This closes the fail safe circuit and provides a signal indicating that an obstruction has been encountered.
- a door drive control system 120, Fig. 6, uses a controller 122 to receive position information 124 form encoder 54 engaged with the shaft of motor 50.
- This position information in conjunction with a preprogrammed format in controller 122, provides the power 126 to motor 50 to control its speed, acceleration and torque dependent upon the particular position. For example, the door after unlocking will move quickly open and then de-accelerate to the full open position. When in the closing mode the door will accelerate quickly at first and then move slowly and smoothly so as to not endanger the passengers. If an obstruction is detected by the presence sensor 90 and/or the contact sensor 32 the door automatically returns to the open position. When it comes to the closed position, increased torque will be applied to seal the door tightly to the cab and facilitate locking. Controller 122 also responds to a number of other inputs. For example, it ceases operation when the closed sensor 58 indicates that the door is closed.
- the controller 122 also disables the contact sensor 32 to prevent the door from reversing to the open position. Controller 122 applies increased torque to secure the seal and allow the door to be locked. When the door is locked, lock sensor 60 provides an indication of that condition and the controller can then maintain a closing force on the door. At any time during the opening or the closing of the door, if the contact sensor 32, that is, the seal on the edge of the door, is collapsed by encountering an obstruction, the controller can interrupt the forward motion and even reverse the motion of the door. Likewise, if the contact sensor 32, that is, the seal on the edge of the door, is collapsed by encountering an obstruction, the controller can interrupt the forward motion and even reverse the motion of the door. Likewise, if the contact sensor 32, that is, the seal on the edge of the door, is collapsed by encountering an obstruction, the controller can interrupt the forward motion and even reverse the motion of the door. Likewise, if the contact sensor 32, that is, the seal on the edge of the door, is collapsed by encountering an obstruction,
- Fig. 7 with most of the door cut away, the view depicts the door in the closed position with seal 32 snugly engaged with sealing surface 84 and the rear linear bearing 26 at its forwardmost position on rail 28.
- linear bearing 22 attached to sliding door 14 is shown in its forwardmost or closed position on rail 18 of lower gui derail assembly 16.
- Lower door seal 150 is an elongated elastomeric member whose larger forward portion 152 functions as a wiper seal on the top surface 154 of lower guiderail assembly 16 of cab 12. Also shown quite clearly in Fig. 9 is the construction of each of the linear bearings as exemplified by linear bearing 22 which includes a housing 156 typically made of aluminum and a bearing material 158 which wraps around but does not completely surround the circular cross-section of rail 28. Housing 156 and bearing material 158 have an opening 160 at the lower end to accommodate the upright stand portion 162 of rail 18.
- Toothed belt 38 is actually a split belt arrangement in which one end 170 is held in position with clamp 172 by means of clamping screws only two of which, 174 and 176, are shown.
- Clamp 172 may have a series of teeth 171 which engage interstitially with teeth 64 on belt 38.
- a second clamp 178 which is adjustable also has teeth 173 which engage with teeth 64 on the other end 180 of belt 38.
- Clamp 178 is also held down by four screws only two of which, 182, 184, are visible in Fig. 10.
- the four screws engage with elongated slots 186, 188, 190, 192, to allow clamp 178 to move to and from clamp 172 and in this way draw the ends 170 and 180 of belt 38 closer to each other or farther from each other. This is done by means of an adjustment bolt 194 which has clearance through hole 196 in clamp 178 and is threadably engaged in bore 196 of clamp 172.
- the door drive arm forms the remainder of the belt tensioning clamp assembly.
- Door drive arm 36, Fig. 10 also includes a magnet 200, Fig. 10, which forms a part of door close sensor 58.
- the presence of magnet 200 is sensed through triple- redundant sensors in head 202 such as three Hall effect sensors 204, 206 and 208 which sense the presence of magnet 200 when the door is in the fully closed position.
- the lock sensor 60, Fig. 12 includes a similar mechanism.
- the lock mechanism itself includes an arm 210 which is pivoted at 212.
- a drive actuator such as solenoid 214 is electrically operated to retract armature shaft 216 in the direction of arrow 218 in the lock mode.
- solenoid 214 is operated to drive shaft 216 in the opposite direction as indicated by arrow 230.
- a fail safe device such as spring 232 or a substantial weight or mass 234 at the other end 236 of arm 210 will cause the arm to rock downwardly as indicated at arrow 238 and thereby automatically move lock detent 224 away from locking surface 228 and unlock the door in case of a power failure.
- the lock sensor 60 operates by means of a magnet 240 mounted on arm 210 and triple redundant sensors such as Hall effect sensors 242 which are
- magnet 240 When arm 210 is in the locked position, as shown in Fig. 12, magnet 240 is centered beneath sensors 242 and the locked position indicating signal is generated. When the arm has been rocked to the unlocked position, either by the spring or weight or by the action of solenoid 214 so that it occupies the position shown in phantom at 210, magnet 240, also shown in phantom, will be remote from sensors 242 and so the lock signal will not be available.
