Definitions

  • This invention relates to vehicle door locking systems and more specifically to switch assemblies for electro-mechanical actuation of locking systems.
  • CDL Central door locking
  • One or more master latch assemblies e.g. latch assemblies of the drivers door and often also that of the front passengerdoor, each include mechanism for locking the respective latch directly by actuation of a key lever when locking the door externally using the door key in conjunction with a lock cylinder of the mechanism, or internally by actuation of a sill lever, typically by manual shifting of a push-pull sill plunger internally of the door. Actuation of either lever causes the associated latch to be locked or unlocked depending on the direction of motion applied. Electrical lock actuation is achieved with the addition of an electro-mechanical actuator usually applied for selective shifting of the sill lever. On some vehicles the sill lever is manually actuated by press button or trigger, e.g. positioned on or adjacent the inside door handle, rather than a push-pull sill plunger but the principle is the same.
  • Arrangement B the dual switch mode, is generally regarded as superior to single switch mode arrangement Aand is favoured for vehicles in the upper price ranges.
  • the object of the invention is to provide greater flexibility of choice between the modes referred to above while utilising substantially standardised components and sub-assemblies so as to reduce manufacture, stock and assembly costs.
  • a multi-purpose switch assembly for a vehicle CDL system comprising a mounting carrying switch contacts, a switch shaft rotatable in or on the mounting for opening or closing the contacts at respective angular positions of the shaft, and actuating levers selectively mountable on the shaft for angular displacement about the shaft axis, said levers comprising a first lever formed to have positive drive connection with the shaft when mounted thereon and to be selectively linked for direct displacement on actuation of door latch mechanism on or in combination with which the assembly is operatively located; and a second lever formed to have drive connection with the shaft, preferably with a degree of lost motion, and to be selectively linked for displacement on actuation of an exterior door key of or associated with said latch mechanism independently of any motion of that mechanism in use.
  • a single switch mode incorporating said assembly and related latch mechanism will be provide by use of the first lever; or a dual switch mode by substituting the second lever.
  • the second lever will conveniently be or will function as a key lever of the latch mechanism in use.
  • the switch shaft will conveniently also carry a key lever of the latch mechanism in use in non-driving engagement thereon for movement independently of the first lever.
  • the invention further resides in the combination of a switch assembly as above defined and a vehicle door latch or latch mechanism and/or a vehicle CDL system including said assembly or said combination; and in a vehicle including the latter system.
  • the switch shaft is conveniently mounted with its axis coincident with the axis of angular movement of a lever of the mechanical locking and unlocking mechanism of that latch, and the first lever, when mounted, will be coupled directly to said mechanism lever for movement in unison therewith.
  • a switch assembly 10 is of unitary construction having its own housing 12 which can be built into or directly mounted on an electro-mechanically actuated door latch assembly of known kind.
  • Switch assembly 10 comprises a switch cam shaft 14 whose operative part within housing 12 includes a pair of angularly spaced radially projecting cam formations 16a, 16b.
  • the switch assembly has three connecting terminals which will be operatively connected to circuitry of the CDL system of the vehicle through a control centre (not shown) of the system in known manner.
  • Afirst terminal 18 leads to a pair of contact blades 20a, 20b shaped to be acted on respectively by formations 16a and 16b when shaft 14 is angularly displaced from a neutral position of rest shown in Fig. 1 in one or other direction during locking or unlocking respectively as referred to hereafter.
  • a return spring 21 may be provided to bias the shaft to said neutral position if it is not positively returned thereto by the action of related mechanism.
  • the second terminal 22 carries a fixed contact 24 against which blade 20a closes when shifted by formation 16a, while third terminal 26 has a fixed contact 28 co-acting with contact blade 20b under the action of formation 16b.
  • Shaft 14 is journalled in and extends through the base of housing 12 as best seen in Fig. 2 (the contact blades 20 and fixed contacts 24,28 are not shown in Figs. 2-4 for clarity) and an O-ring seal 30 prevents ingress of dirt and oil which might otherwise reach the switch contacts.
  • the end portion 32 of shaft 14 remote from formation 16 and extending outside housing 12 is generally cylindrical and terminates in radially outwardly projecting lips 34. Parts of the cylindrical wall of portion 32 are cut away at diametrically opposite locations to provide drive notches 36 (one only visible in the drawings). These notches also permit limited flexure of the remaining wall parts enabling snap engagement with a lever or levers referred to hereafter. Said engagement is sufficient at least to retain the lever(s) in place up to final positioning of the assembly in or on the latch. Snap engagement may alternatively be provided by local deformation of lips 34 alone.
  • FIG. 3 shows the arrangement for single switch mode and also illustrates the relationship of the completed switch assembly 10 to the relevant portions of the latch assembly 40.
  • the latter includes a lever 42 which is an active part of the latch mechanism of the latch itself, switch assembly 10 being operatively so mounted that switch cam shaft 14 is coincident with the axis of angular movement of lever 42 during the mechanical locking and unlocking of the particular latch, this movement taking place regardless of whether actuation is by movement of a key barrel using an exterior key of the door or by operation of a sill button or other interior manual locking and unlocking actuator or otherwise.
  • switch assembly 10 is adapted to sense and respond directly to movement of lever 42 by being coupled to the latter through the medium of a first sensing lever 44 having an apertured boss 46 which is a push fit onto portion 32 of shaft 14 and which includes radially inwardly directed drive lugs 48 (one only shown) positively drive connecting it to shaft 14.
  • An arm 50 of lever 44 projects radially from boss 46 and is shaped to include a formation (not shown) which locates in an aperture in latch lever42 to couple lever 44 directly thereto for movement in unison therewith.
  • Boss 46 occupies an axially inner part of portion 32 and a key lever 52 locates by snap engagement as aforesaid on the remaining outer part.
  • a boss 54 of lever 52 is apertured to be journalled on shaft 14 but does not include any engaging lugs so that it can move angularly independently of said shaft and of lever 44.
  • Key lever 52 has an arm 56 which will be operatively linked to and be moved by rotation of the key barrel for mechanical locking and unlocking of the latch in known manner.
  • a second and different sensing lever 60 is provided on its own. This lever serves as the key lever of the associated latch.
  • Lever 60 has a deeper boss 62 occupying the full length of shaft end portion 32 and snap engaging thereon as referred to above.
  • the central aperture of boss 62 includes a pair of drive lugs 64 (one only shown) which engage in the notches 36 of shaft 14.
  • lugs 64 are less in angular width than the associated notches 36 so that there is a degree of lost motion in the drive between lever 60 and switch cam shaft 14.
  • lever 60 when lever 60 is displaced angularly in either direction in its function as key lever on locking or unlocking respectively from the neutral position shown in Fig. 4 there will be a lag before it moves shaft 14 from its neutral position to close one or other of the pairs of switch contacts.
  • Lever 60 co-acts with the latch mechanism through lever 42 in known manner when the exterior door key is used to mechanically lock and unlock the associated latch directly.
  • the latch serves as the master unit, with related electro-mechanical actuation of the remaining locks of the vehicle through operation of the switch contacts as part of the CDL system as referred to above.
  • switch assembly 10 is not affected by shifting of the latch mechanism itself or by operation of the interior sill button or equivalent.
  • a second switch will be provided for effecting central locking from the interior of the vehicle from a button or other auxiliary control element as referred to above.
