Definitions

  • the present invention relates to a vehicle headlamp.
  • the present invention relates in particular to a headlamp of the type comprising a reflector of stamped or die-cast plastic material provided with an axial rear opening engaged by a lamp which is kept connected to the reflector by a locking device which can be released.
  • the locking devices known up to now used to lock the lamp on such a reflector normally comprise an outer metal ring mounted on the end of the reflector and forming a bearing seat for an intermediate flange of the lamp.
  • These known locking devices normally comprise two axial projections, which extend rearwards from diametrically opposite points of the metal ring, one of which forms a hinge connection for a respective end of a leaf spring and the other forms a hook for the other end of the leaf spring when the leaf spring itself is disposed in a locking position, in which an intermediate curved portion of the spring presses elastically on the intermediate flange of the lamp, maintaining the lamp in contact with its seat.
  • the object of the present invention is to provide a vehicle headlamp which is free from the above drawbacks.
  • a vehicle headlamp comprising a reflector of plastic material provided with an axial rear aperture, a lamp mounted through this rear aperture and having an intermediate flange so that it can be supported on the reflector and a locking device which can be released for holding the lamp in connection with the reflector, characterized in that the reflector comprises, in one piece, a seat surrounding the aperture and acting as a support for the intermediate flange and in that the locking device comprises a bistable elastic member and snap-locking means for connecting the bistable elastic member to the reflector, the bistable elastic member being adapted to be switched between a configuration locking the lamp on the seat and an assembly configuration in which the lamp can be inserted into and disengaged from the seat.
  • a vehicle headlamp is shown overall by 1 and comprises a reflector 2 formed from stamped or die-cast plastic material and having an optical axis 2a, a lamp 3 and a locking device 4 for locking the lamp 3 on the reflector 2.
  • the reflector 2 has an outer surface 5 from which there projects rearwards a cylindrical projection 6 coaxial with the axis 2a and having a through bore 7 engaged by the lamp 3, an intermediate flange 8 of which engages with an axial seat 9 provided on the free end of the projection 6 about the bore 7 and is disposed in contact with a base surface of the seat 9.
  • the locking device 4 comprises a bistable elastic member 14, an intermediate portion of which is formed by a flat elastic blade 15 of substantially rectangular shape which has two longitudinal slots 16 disposed symmetrically with respect to a longitudinal axis of the blade 15.
  • the length of the slots 16 is less than the length of the blade 15 and the slots provide on the blade 15 two bars 17 and 18 disposed on opposite sides of a central elastic member 19 which is formed by a bar similar to the bars 17 and 18 but having transverse corrugations 20 which reduce the distance between its opposite ends to a value slightly lower than the distance between the corresponding opposite ends of the bars 17 and 18.
  • the corresponding ends of the bars 17 and 18 and of the elastic member 19 are rigidly connected by two end crossbars 21 and 22, the first of which is rigid with a pressure member 23 adapted to cooperate with the flange 8 so as to hold this flange 8 in contact with the base surface of the relative seat 9 and the second of which is rigid with a member 24 for connecting the bistable elastic member 14 to the reflector 2.
  • connection member 24 comprises an arm 25 extending in a direction substantially perpendicular to the blade 15 and having, in cross-section, substantially the shape of a C.
  • An end section of the arm 25 is folded into a U shape so as to form an elastic hook 26 adapted to allow the snap-locking of the arm 25 within a hole 27 provided axially along a projection 28 projecting rearwards from the outer surface 5 of the reflector 2 and provided in one piece by stamping with the reflector 2.
  • the projection 28 is disposed on the reflector 2 laterally to the projection 6 and at a distance from the optical axis 2a substantially equal to the total length of the blade 15 and the pressure member 23.
  • an end surface 29 of the projection 28 forms a bearing surface for the crossbar 22 one end of which has connected to it an end blade 30 for the connection to the elastic member 14 of an earth wire (not shown).
  • the pressure member 23 extends from the crossbar 21 coaxially to the blade 15 and is subdivided, by axial notches, into three arms 31, 32 and 33, the first two of which, disposed on opposite sides of the arm 33, each have an end portion 34 folded into the shape of a C and adapted to come into contact with the rear surface of the flange 8, while the arm 33 is folded substantially at right angles with respect to the blade 15 and extends from the opposite side of the end portions 34 to form a lever for the actuation of the bistable elastic member 14.
  • the bistable elastic member 14 may be connected directly to the reflector 2 without the interposition of any metal connection member and that the seat 9 may be provided directly on the reflector 2 without the need for any metal insert.
  • bistable elastic member 14 as it is snap-locked to the reflector 2, may be readily replaced without needing any destructive action on the reflector 2.
