No. 13/608,303, filed Sep. 10, 2012, entitled “FLUSH-MOUNTED DOOR HANDLE FOR VEHICLES,” which claims the benefit of U.S. Provisional Application No. 61/666,493, filed Jun. 29, 2012, entitled, “FLUSH-MOUNTED DOOR HANDLE FOR VEHICLES,” the entire disclosures of each of which are incorporated herein by reference.
- The present invention relates to flush-mounted door handles for vehicles that may utilize a powered latch.
- Vehicle door handles typically protrude from the door, and interfere with vehicle styling and/or aerodynamics. Various outside door handles such as paddle type handles, pull-strap handles, push-button activated handles, and the like have been developed. However, known conventional door handles may suffer from various drawbacks.
- One aspect of the present invention is a flush-mounted door handle that is operably interconnected with an electronic door latch release for motor vehicles of the type having a door with a door structure and an outer surface and/or keyless entry feature and/or a styled (“Class A”) outer surface portion. The handle outer surface is defined by the styled surface of the vehicle, and may comprise a portion of the substantially continuous portion of the styled outer surface. The handle is flush to the door frame outer surface which is covered with a Decorative Class part known as the appliqué. A sensor is mounted to the door at a location adjacent the portion of the outer surface defining a surface contour. The sensor is selected from the group consisting of proximity sensors or touch sensors. The release system may also include a visual indicator on the door that is configured to convey the general location of the sensor to a user. The visual indicator may comprise a light, a marking or the like on the surface of the door, a recessed pocket, or other indicia or irregularity on the outer side of the door. The door latch release system further includes a powered latch that retains the door in a closed position when the latch is in an engaged configuration, and permits opening of the door when the latch is in a release configuration. The powered latch shifts from the engaged configuration to the release configuration if the sensor generates a predefined signal indicating that a user has actuated the sensor/switch. The system may include a handle formed by a recess in an outer side or surface of the door. A flange or other structure extends across a portion of the recess to form a pocket that provides an inwardly-facing grip surface that allows a user to pull the door open without movement of the handle relative to the vehicle door. The system may include a receiver also known as door control unit (DCU) that utilizes a signal from a security transmitter (e.g. keyless entry fob). The system may include a proximity (e.g. capacitive) or a touch sensitive pad (e.g. piezoelectric or other pressure/force detection sensor) that is operably connected to the sensor, and is actuated when a user touches the sensor or other surface. The system may comprise a handle located above the door belt line in a vertically extending portion of a door frame adjacent to a window of the door. The handle may comprise a vertically elongated opening, recess or depression into the door having a surface that faces outwardly. The system may also include a touch keypad with numbers that are normally hidden, but illuminate when the hidden keypad is touched. The keypad may be utilized to enter security codes or the like.

No. 8,573,657 the entire contents of each of these applications being incorporated herein by reference. Poweredlatch 16 has locked and unlocked states corresponding to manual door locks. Switch orsensor 15 is typically included inhandle assembly 10 ifhandle assembly 10 does not include a Passive Entry Passive Start system (PEPS). A PEPS system typically includes a fob that can be detected by an antenna in the vehicle. The PEPS controller unlocks the vehicle door(s) if it senses an authorized fob, and locks the doors after the fob/user is inside the vehicle. Because the vehicle is locked/unlocked based on detection of an authorized fob, no pushbuttons or other specific manual input by a user is required for operation or a PEPS system. - In vehicles that are not equipped with a PEPS system, a
user pushbutton 15 or other suitable input (e.g. remote fob with pushbutton lock/unlock feature) is utilized. A sensor symbol orindicia 15A may be provided to enable a user to locate thesensor 15.Indicia 15A may comprise lines that are printed onouter surface 11, or thesensor symbol 15 may comprise side-by-side raised ridges and grooves that form lines, a pad lock icon, or the like.Sensor 15 may comprise a push button that unlocks the vehicle doors in substantially the same manner as known remote pushbutton fobs/powered door locks. The surface ofindicia 15A may comprise a membrane or the like to permit manual switch activation. Still further, the sensor symbol/indicia 15 could include an LED light or the like that illuminates when the presence of a specific key fob (not shown) is detected and a user touches this area ofsurface 11. Thehandle assembly 10 may further include anilluminated lock symbol 15B that lights up when the vehicle is locked, and may be configured to fade to a non-illuminated state after a predefined time period (e.g. 5, 10, or 30 seconds, or a predefined number of minutes). - Instead of a pushbutton,
sensor 15 may comprise a proximity locking sensor 44 (see alsoFIGS. 4-6 ) on the back side ofindicia 15 that allows a user to lock the vehicle without using the key fob by moving his/her hand into a predefined detection range. Anunlatch sensor 46 may be located on the backside of the handle class A surface and it may extend along a majority of the grip length of the handleadjacent edge 33 which the user activates via proximity or touch. Once the key fob presence is detected (range is 1m) the vehicle owner is authenticated by the vehicle's keyless entry module via the established communication protocol between the vehicle owner's key fob, via anLF antenna 18 packaged inside themodule housing 36 facing the outer surface of the handle (i.e. behind the class A surface), the DCU and the BCM body control module. - In summary, there are typically at least three electrical elements included in the entry system: 1) a proximity or
touch lock sensor 44; 2) a proximity ortouch unlatch sensor 46; 3) a LF Antenna. Front andrear door handle - The
surface 18 may comprise an antenna that is operably connected to a low frequency receiver to thereby determine if a specific key fob is within a predefined distance. A piezoelectric touch sensor or capacitive (i.e. proximity) unlatchsensor 46 may be positioned behind theantenna layer 18. A series of numbers of other indicia may be utilized to form thekeypad 20.Keypad 20 can be actuated by a user touching thesurface 11 in the region of theindicia 20. In the illustrated example, the indicia forming hiddenkeypad 20 comprise numbers that are visible only when lit. For example, each number may comprise a lens or aperture having the shape of the number, and an LED or other light source may be positioned behind the aperture. When thehandle assembly 10 detects the presence of a user as a result of a key fob being present and as a result of touchingsurface 11, the LEDs may light up, thereby causing theindicia 20 to illuminate and become visible. The hiddenkeypad 20 permits a user to enter a specified code to thereby authorize entry. Achrome strip 22 or the like may extend vertically to visually divide thesurface 11 and provide a distinctive appearance. - Referring again to
FIG. 3 ,recess 12 may comprise a shallow inwardly depressed curvedconcave surface 23 of upwardly extendingportion 7 ofdoorframe 6 that forms a pocket for receiving a user's fingers. Alternately, the outer surface may comprise an outwardly-protruding surface 11A having inner surface 24A. Ifhandle 10 includes an outwardly-protruding surface 11A,surface 23 may be shallow, or flush withouter surface 8. Themodule 14 may extend inwardly to cover a portion ofrecess 12 and form an inwardly facingsurface 24.Surfaces inner corner 25. The handle is positioned at an ergonomic location on thedoor handle surface 11 and unlatch thedoor door recess 12 described earlier to control thedoor concave surface 23 may be partially or completely formed in the front pillar structure ofrear door 3, or it may be formed in an outer surface (e.g. surface 5) of the door. Thus,edge 33 andinner surface 24 may be formed by the vehicle door and the concave, outwardly openingportion 23 may be formed by the vehicle body. - With further reference to
FIG. 4 , handleassembly 10 includes amodule housing 36 disposed in anopening 114 defined byedge 118 ofappliqué 7.Module housing 36 is formed by outer andinner members FIG. 5 ), which members may comprise a molded polymer material.Module housing 36 is secured toinner door structure 92 by conventional screws or threadedfasteners 94 and nuts 96. Threadedfasteners 94 extend throughopenings 98 in flange(s) 102 ofinner member 106. Flanges ortabs 108 ofouter member 104 are received in channels 120 (FIG. 5 ) formed insidewalls 110 ofinner member 106.Screws 112 or other suitable fastening arrangement interconnect outer andinner members tabs 108 may comprise barbed members, andchannels 120 may comprise corresponding snap fit connectors. Barbed connectors of this general type are well-known, and the details of the connection oftabs 18 andchannels 120 will therefore not be described in detail herein. Outer andinner members interior space 115. When fully assembled, keyless entry module 14 (FIGS. 6 and 7 ) is disposed inspace 115. A finger access pocket 117 (FIG. 4 ) is formed/molded integrally into theappliqué 7. - When
layer 26 and housing 28 are assembled, amodule housing 36 is formed. In the illustrated example, thehousing 36 has aquadrilateral perimeter shape 38 when viewed from the front (FIG. 6 ), and it also has a quadrilateral perimeter shape 40 in edge view (FIG. 7 ). It will be understood that the shape and size of theperimeters 38 and 40 may be configured as required for a particular application. With reference toFIGS. 6 and 7 , keyless entry module orsubassembly 14 has a six-sided housing 136. A transverse interior wall 41 divides the interior space ofhousing 136 into a first compartment orspace 42 and a second compartment orspace 43. The sidewalls of themodule housing 36 have thicknesses “W1,” “W2,” “W3,” “W4,” and “W5.”Housing 136 may comprise a polymer or other suitable material.Lock sensor 44 is disposed in space orcavity 42. Thelock sensor 44 may be a piezoelectric (touch) or capacitive (i.e. proximity) sensor. As discussed in more detail below, after closingvehicle door 2, a user actuates lock switch/sensor 44 to cause thelatch 16 to shift to a locked configuration. This may be done by touch ifsensor 44 is a touch-sensitive switch, or by moving a hand into the vicinity ofsensor 44. As shown inFIG. 7 , theantenna 18 may be disposed on an inner side of the layer ofmaterial 26 within cavity orspace 43 such thatantenna 18 faces outwardly whenhandle 10 is fully assembled to avehicle door 2.Unlatch sensor 46 comprises a piezoelectric or capacitive sensor that is disposed on asidewall 48 ofhousing 36.Sensor 46 determines if a user has touchedmodule 14, or is within a predefined distance ofmodule 14, to thereby unlatchpowered latch 16. - The
module 14 may include one or more LED lights 49 or a light pipe (FIGS. 6, 7 ) that are configured to illuminate the keypad numbers and also finger access pocketouter surface 12. The LED light for pocket illumination faces inward towardspocket 12 where as the LED lights for keypad numbers face outward towardssurface 26.Surface 26 comprises a clear plastic that is painted black and laser etched to form the keypad numbers/openings adjacent toantenna layer 18 to permit light from an internally mounted LED light source 49. LED light source 49 is positioned such that it does not interfere with the function or package space of the antenna and illuminates theouter layer 26.Outer layer 26 may comprise a light-transmitting material (clear plastic can be painted black and the illumination area laser etched) for a particular application. Thepocket 12 also can be illuminated to guide the user to the area where to place his/her fingers. For example, an LED 49 may be configured to light up if the system senses an authorized keyless fob in the vicinity, or if a correct security code has been entered utilizing the hiddenkeypad 20. Also, an LED 49 may light up when poweredlatch 16 shifts to an unlatched state. The LEDs 49 may have different colors to signify a “positive” result (e.g. an authorization code has been recognized by the system), and a different color (e.g. red) may be utilized to indicate that a “negative” outcome has occurred (e.g. the system determines that an incorrect authorization code has been entered utilizing the hidden keypad 20). - In use, if
powered latch 16 is in a locked configuration, and a user approaches thevehicle 1,antenna 18 detects if the user has a keyless entry fob having a security code that is recognized by the system. If the system (e.g. keyless entry/door controller module 13) detects an authorized security code, the user is then authenticated, and thecontroller module 13 is in an “authenticated” state. If a user has been authorized, the user can then place his or her hand (or other object) within a predefined distance of sensor 46 (ifsensor 46 comprises a capacitive sensor), andcontroller module 13 will generate a signal to thepowered latch 16, which causes thelatch 16 to shift to an unlatched configuration. Alternately, ifsensor 46 comprises a piezoelectric or other touch sensor, a user can touch theback side surface 24 ofmodule 14, andcontroller module 13 will then generate a signal causingpowered latch 16 to shift to an unlatched configuration. Still further, the system may utilize a security code that is entered utilizing the hiddenkeyboard 20. The system may be configured to require a key fob for authenticating the vehicle owner. - After the
powered latch 16 shifts to the unlatched position, a user may insert his or her fingers into outwardly facing recess 12 (FIGS. 2 and 3 ), and curl the ends of his or her fingers aroundedge 33 to contact inwardly facingsurface 24. A user then pulls thedoor 2 to an open position. When a user closes the door, it may be closed initially in a conventional manner by swinging the door shut. This causes thepowered latch 16 to shift to a latched configuration, holding thedoor 2 in a closed position. If a user desires to lock the door from the outside, he or she actuates sensor 44 (FIGS. 6 and 7 ) by touching the surface ofmodule 14 adjacent the sensor symbol 15 (FIG. 5 ), or by bringing his or her hand sufficiently close tosensor 44 ifsensor 44 comprises a capacitive sensor. - With further reference to
FIGS. 8 and 9 , ahandle 150 according to another aspect of the present invention includes a polymer core member or element that is connected to edge 154 ofsheet metal 156 utilizinghooks 158 or other suitable connector.Sheet metal 156 may be bent or formed inwardly to form arecess 166. Aportion 168 ofrecess 166 is in the form of a pocket formed bycore element 152. Anappliqué 7A connects to core element ormember 152 utilizingbarbed connectors 162 or the like.Appliqué 7A andcore member 152 together define aspace 164. A module 14A that is substantially the same asmodule 14 is disposed inspace 164. Module 14A is positioned such thatantenna 18A faces outwardly and sensor 46A faces inwardly. - The
flush handle assembly 10 described above in connection withFIGS. 1-9 eliminates the need for a movable, protruding handle assembly and associated components. This provides a more aesthetically pleasing appearance, reduces complexity, assembly labor, cost and improves vehicle aerodynamics and quality. - The
flush handle assembly 10 has been shown and described mounted to an upwardly extendingportion 7 of adoor frame 6. However, thehandle assembly 10 may also be positioned in the lower portion of door 2 (FIG. 1 ) belowbeltway 3. In general, thehandle assembly 10 is positioned relatively close to theouter door edge 9 oppositefront edge 17 ofdoor 2 to thereby facilitate ergonomically pleasing opening/pivoting of the door by a user. - It is to be understood that variations and modifications can be made to the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
