Definitions

  • This invention relates to the field of automative door opening and closing systems, and particularly to an integrated system of components that transport an automotive sliding door through its range of motion while providing adequate user safety.
  • Vans Sliding doors are widely used on the class of vehicles generally referred to as vans. Vans typically have normal swinging front doors and one or more sliding side doors. These types of sliding doors translate out of the side opening in the vehicle to facilitate ingress/egress rather than rotating, as is the more common motion of automotive closures.
  • the most common and widely used sliding door system consists of three body-mounted tracks (3) and three corresponding door-mounted hinge/roller assemblies (15), as illustrated in Figures 4 and 5.
  • the body mounted tracks are normally located at the roof, floor and mid-positions on the side of the vehicle with the roof-position and floor-position components being arranged in-line with the door opening and the mid-position (centre) track located rearward of the side opening. It is normal practice to utilize the lower and centre tracks to carry the vertical weight of the door.
  • the travel path of the door is therefore defined by the track shape and articulation of the hinge/roller assemblies.
  • the present invention is targeted at reducing the complexity of automatic sliding door opening/closing systems. It specifically eliminates electronic obstruction detection by utilizing a mechanical arrangement and additionally provides uncompromised manual performance by completely decoupling the power system.
  • an automatic sliding door opening/closing system comprises a continuous, powered belt drive system located on a vehicle body; and a clamp arrangement capable of fixably attaching a vehicle door to the belt drive system so as to be automatically driven along a predetermined path and capable of releasing under predetermined conditions.
  • the powered belt drive system is located so as to be combined with one of a standard hinge system's three body tracks.
  • the clamp arrangement is attached directly to one of the standard door hinge/roller assemblies on the door.
  • the clamp arrangement is a rotary device biased into a pinching action on the belt via a cam and spring arrangement, and the rotary device is arranged so as to release from the belt at a predetermined force threshold.
  • the powered belt drive system incorporates two belt tensioning devices, located on opposite sides of the clamp arrangement, capable of providing the required belt slack to facilitate movement of the rotary clamping device into a pinching engagement with the belt.
  • a continuous belt drive system (1) is located so as to be combined with one of the three body mounted tracks (3) (see also Figures 2, 4 and 5) utilized in conventional automotive sliding door systems.
  • This drive system comprises a continuous-loop belt (5), electrical motor (7) and drive pulley (9), two belt-tensioning devices (11) and a number of idlers (13) used for belt routing. Idlers are typically unpowered, rotatable pulleys.
  • the belt drive system is configured so that the belt (5) rides over a roller (21) and is exposed on the outer side of the track (3) so that it is adjacent to the corresponding door mounted hinge/roller assembly (15).
  • the belt drive system is configured to be driven by the electrical motor (7) in both directions.
  • This clamp is configured so that it can be biased to pinch the belt into a clamping condition against the roller (21) so that when the belt is driven by the motor (7) the door (19) is drawn along the path defined by the hinge/roller/track configuration.
  • the clamp (17) is biased so that it is held in the pinch condition until a predetermined belt load is exceeded, at which point it moves out of the pinch condition and releases the door (19) from the belt drive system (1).
  • the clamp (17) is in the non-pinch condition, the door (19) can be moved along the path defined by the hinge/roller/track configuration with no interaction with the belt drive system (1).
  • a power actuator (not shown) is configured to move the clamp (17) back into the pinch condition with the belt (5).
  • the belt drive system has the capability to pull the door into the first position of the main door latch (i.e. the secondary latched position) and a power pull-in latch (not shown) is used to achieve full primary latching.
  • An electronic control system and associated sensing transducers (not shown) are used to co-ordinate and actuate the belt drive motor (7), clamp actuator and main latch.
  • the clamp (17) comprises a rotary device which is biased into the belt pinch position via a cam (22) interacting with a ball (25) and compression spring (27).
  • the compression spring (27) pushes the ball (25) into a cam pocket (23), integral with the rotary clamp which maintains the device in the pinch position.
  • the surface of the clamp (17) that engages the belt (5) in the pinch position incorporates serrations (29) which enhance the pinching action and minimize the possibility of slippage between the belt (5) and clamp (17).
  • the rotary clamp (17) disengages from the belt (5) when an obstruction in the path of the door (19) causes the belt load to exceed a predetermined threshold.
  • the threshold load is defined by the cam profile, spring force and spring pre-compression.
  • a power actuator is attached to the hinge/roller assembly which rotates the clamp (17) back into the pinch condition with the belt (5) upon receiving an electromagnetically-communicated command, such as from a push button located within the van, or from a key fob button.
  • the belt drive system must be capable of providing the necessary belt slack to allow the rotary clamp (17) to fully rotate to the pinch position.
  • This belt slack is provided by two belt tensioning devices (11), located on opposite sides of the clamp arrangement, which are capable of providing belt slack when the system is not driving the door but can lock when required to transmit belt load. An additional function of these tensioners is to compensate for belt stretch as the system is subjected to prolonged usage.
  • the rotary clamp system may also be utilized in conjunction with a power pull-in latch, electronic control system and associated sensing transducers.
  • the clamp system is designed to disengage when the door reaches its fully open or fully closed positions by reacting to the overload condition in the same way as in the case of an obstruction.
  • the system remains in a manual mode until it receives a signal to operate automatically. This signal initially causes the main latch to disengage (when in the closed position) followed by the actuator engaging the belt clamp into the pinch position and finally by running the belt drive motor until either an obstruction or full motion causes the clamp to release.
