  • this invention is related to a key module mechanism for an electronic door lock, comprising: a key, a key receiving assembly, and a first circuit board.
  • the key includes an upper and a lower planar surface, wherein the lower surface is provided with two linear, parallel, distant, and raised guide rails.
  • the key is provided with an IC circuit for storing a password therein.
  • the IC circuit extends to form two contacts that are connected to a front end of the key.
  • the key receiving assembly includes a key socket and a socket frame.
  • the key socket is formed with a key opening.
  • the key opening is formed along an inner bottom thereof with two guide grooves that accommodate the guide rails, such that the key opening adapts to allow precise insertion of the key.
  • the first circuit board is placed next to a rear end of the key socket.
  • the first circuit board is provided with circuits to process password signals received from the key, and two conductive plates secured to the first circuit board.
  • Each of the conductive plates includes a contact located out of a tail end of the key opening, such that when the key is inserted into the key opening and the contacts located at its front end protrude out of the tail end of the key opening, the contacts may be in contact with the contacts of the conductive plates for signal transmission.
  • This invention further discloses an electronic door lock incorporating the above key module mechanism with a lid, a case, and a second circuit board.
  • the mechanism A comprises a key 10, a key receiving assembly 20, and a first circuit board 30.
  • the key 10 includes an upper and a lower planar surface 11, 12, wherein the lower surface 12 has two linear, parallel, distant, and raised guide rails 13.
  • the key 10 is provided with an IC circuit (not shown) for storing a password therein.
  • the upper surface 11 may be provided with four encoding apertures at, but not limited to, locations 141 to allow writing the password into the IC circuit of the key.
  • the IC circuit extends to form two contacts 14 that are connected to an inwardly drawn front end of the key 10 (see Fig.
  • the upper surface 11 of the key 10 is provided with triangular, indent arrow 16 adjacent a front end thereof to indicate the insertion direction of the key 10 while performing unlocking.
  • the upper surface 11 is provided with a label indent 16 at a central portion thereof to allow adherence of an identification label (such as company name and lock serial number, not shown).
  • the upper surface 11 may be further provided with a pendent opening 17 adjacent a rear end thereof.
  • the key receiving assembly 20 includes a key socket 21 and a socket frame 22 which can be integrally formed by injection molding and joined by flaps 25.
  • the key socket 21 is formed with a penetrative key opening 23.
  • the key opening 23 is formed along an inner bottom thereof with two guide grooves 24 that accommodate the guide rails 13, such that the key opening 23 adapts to allow insertion of the key 10.
  • the key socket 21 is formed with a block 211 at a location corresponding to a midway point of the two contacts 14 of the key 10 to prevent the key 10 from colliding with the first circuit board 30 due to over-insertion of the key 10 into the socket 23.
  • the socket 21 further extends rearwards to form two vertically aligned locating pins 212 which adapt to be inserted into holes formed between the two conductive plates 31 of the first circuit board 30.
  • the socket frame 22 is provided to support and secure the key socket 21.
  • the socket frame 22 is in a C-shaped configuration and is provided at a front side thereof with an opening 222 and guide grooves 223 corresponding to the key opening 23 and guide grooves 24, respectively.
  • the first circuit board 30 is placed next to a rear end of the key socket 21 and is secured by hooks 26 provided on a tail end of the socket frame 22.
  • the first circuit board 30 is provided with circuits (not shown) for processing password signals received from the key 10.
  • the two conductive plates 31 are secured to the first circuit board 30, where each of the conductive plates 31 is formed by bending a copper sheet with projective insertion tabs 312 provided at staggered locations of opposing sides and a tail end thereof, wherein the tabs 312 are inserted into openings 313 formed at corresponding locations of the first circuit board 30 and then secured by soldering to attain a solid construction.
  • Each of the conductive plates 31 includes a contact 311 at the top end thereof.
  • the contacts 311 are located within the key opening 23, such that the key contacts 14 may be in contact with the contacts 311 of the conductive plates 14 upon insertion of the key 10 into the key opening 23 to allow unlocking/locking by means of electronic signals.
  • the first circuit board 30 is provided with an LED indicator 32 at an appropriate location to indicate the status of the unlocking or locking.
  • the lighting signal is guided by a light transmitting plate 221 secured above the key socket 21 so as to be illuminated at the front end of the key socket 21. As shown in Figs. 1 and 3, the light transmitting plate 221 projects through an opening 224 formed on the socket frame 22.
  • a sidewall with a cavity 27 is formed for containing a retaining plate 28 by means of a pin 281.
  • the retaining plate 28 includes a triangular, projecting engaging portion 282.
  • the key 10 is formed at a right side edge thereof with a V-shaped notch 18 that matches the triangular configuration of the engaging portion 282 of the retaining plate so as to provide the feel of the key 10 being in place. Furthermore, as shown in Fig.
  • an incident angle ⁇ 1 and a reflected angle ⁇ 2, preferably 35.85° and 48.37° respectively, are formed between a tip of the triangular engaging portion 282 and a vertical line VL, such that the forces required for insertion and withdrawal of the key 10 are substantially equivalent.
  • the key module mechanism 1 is installed within a lid 40 and a case 50.
  • the lid 40 is formed at a front edge thereof with an opening 41 dimensioned to correspond to the key opening 23.
  • the opening 41 is formed at a bottom thereof with two parallel guide grooves 42 to allow insertion of the key 10.
  • the case 50 is further provided with a second circuit board 51 including circuits for decoding the password signals transmitted by the key 10, and incorporating the key receiving assembly 20 and the first circuit board 30 thereon.
  • the lid 40 is then joined above the case 50.

  • the cover plate 45 Prior to insertion of the key 10 into the key opening 23 through the opening 41, the cover plate 45 is in a closed state due to biasing of the spring 44 so as to shut the opening 41 (see Fig. 4); after insertion of the key 10 into the key opening 23 through the opening 41, the cover plate 45 is toppled to assume an open state (see Fig. 5).
  • the lid 40 is further provided with a light permeating plate 46 at a location corresponding to the light transmitting plate 221 such that the lighting signal of the light transmitting plate 221 is guided and emitted through the light permeating plate 46 for a user's detection.
