Abstract
Description
- The present invention relates to an outside vehicle handle. As is known, vehicle handles normally comprise a fastening structure connected integrally to the inside of a door; and an outside grip hinged to the fastening structure and user-operated to release a lock on the door.
- Handles are known which comprise a sensor, in particular an antenna, for detecting the presence of a user about to open the door, and for emitting a relative warning and/or user-recognition signal. The bare sensor is inserted inside a cavity in the grip, and is connected to output wiring for transmitting the signal to a central control unit on the vehicle, which enables release of the lock.
- Known handles of the above type have various drawbacks. Despite the cavity in the grip being closed by a plug, the sensor is subject to frequent malfunctioning caused by external agents, such as dust or damp, infiltrating the cavity, and which, on coming into contact with the sensor, result in detection and/or signal transmission errors preventing the user from releasing the lock.
- Moreover, to make them softer to the touch, a demand exists for grips made of soft or flexible material. When gripped by the user, however, a flexible grip may generate stress on, and so possibly damage, the sensor.
- It is an object of the present invention to provide an outside vehicle handle designed to provide a straightforward, low-cost solution to the above problems.
- According to the present invention, there is provided an outside vehicle handle; the handle comprising a grip defining a grip portion gripped by a user; and user presence detecting means carried by said grip and comprising sensor means at least partly housed in said grip portion and for detecting the presence of said user and emitting a relative output signal, and transmission means for transmitting said output signal; characterized in that said detecting means comprise a protective casing housing said sensor means; and said transmission means being at least partly carried by said protective casing.
- A non-limiting embodiment of the invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a partial section of a first preferred embodiment of the outside vehicle handle according to the present invention;
- Figures 2 and 3 are similar to Figure 1, and show exploded views, with parts removed for clarity, of a first and second variation of the Figure 1 outside vehicle handle respectively.
-
- Number 1 in Figure 1 indicates an outside handle (shown partly) for a vehicle side door (not shown). Handle 1 comprises a fastening structure 3 (shown partly and schematically) which is fitted inside and connected integrally to the door in known manner not described in detail.
- Handle 1 also comprises a
grip 4 made of plastic material and, in turn, comprising anintermediate grip portion 5, which is gripped by a user, is elongated along an axis A substantially parallel, in use, to a longitudinal direction of the vehicle, and defines an axial inner cavity 7. - At one end,
portion 5 defines anopening 9, which is formed along axis A, defines an inlet of cavity 7, and is closed by a wall 11 inserted axially inside opening 9 and fixed in fluidtight manner toportion 5. - As shown in Figure 1,
grip 4 also comprises twoend portions portion 5 and extend throughstructure 3 from opposite axial ends ofportion 5.Portion 14 is connected to a lock (not shown) on the door in known manner not shown, andportion 13 is connected tostructure 3 to enable the user to movegrip 4 to release the lock. -
Portion 13 defines a cavity 17 closed by aplug 18 defining, together withportion 13, achannel 20 communicating with cavity 7 andhousing wiring 21. - Wiring 21 forms part of a detecting
device 22 carried bygrip 4 and comprising a sensor defined, in particular, by an antenna 24 (shown by the dash line) for detecting the presence of a user about togrip portion 5, and for accordingly emitting a relative output signal. -
Device 22 also comprises a substantially parallelepiped-shaped casing 26, which housesantenna 24, is in turn housed inside cavity 7, and is formed in a singlerigid body 27, preferably of plastic material, or, according to a variation not shown, in two bodies connected in fluidtight manner. - The axial end of
casing 26opposite opening 9 defines asurface 30, which is perpendicular to axis A and supports an electric connector 29 (shown schematically) connected in fluidtight manner tobody 27 and preferably co-molded withbody 27. - The connector is connected electrically, on one side, to
antenna 24, and, on the other, to a further electric connector 31 (shown schematically) to transmit said output signal.Connector 31 partly defines cavity 7, is connected electrically to wiring 21, and is fixed, e.g. glued, toportion 5 in known manner not described in detail. - As shown in Figure 1,
connectors - More specifically, when assembling handle 1, after fixing
connector 31 toportion 5 and to wiring 21,plug 18 is closed, andcasing 26 is inserted axially inside cavity 7 through opening 9. After insertingcasing 26 so as to mateconnectors casing 26 toportion 5. - The Figure 2 variation relates to a handle 1 comprising a
grip 34, the component parts of which are indicated, where possible, using the same reference numbers as in Figure 1. -
Grip 34 has noplug 18, i.e.channel 20 is formed entirely throughportion 13; and cavity 7 has anelongated inlet opening 39 formed in alateral face 40 extending along axis A and, in use, facing the body of the door to which handle 1 is fitted. -
Opening 39 is closed by awall 41, which is pressed intoopening 39, is fixed, e.g. glued, in fluidtight manner to the rest ofportion 5 in known manner not described in detail, and, once fixed, forms an extension offace 40. -
Antenna 24 is housed in acasing 46, which differs fromcasing 26 substantially by supportingconnector 29 on a lateral surface 47 parallel to axis A; andconnector 31 is aligned withconnector 29 and with opening 39 in a direction B perpendicular to axis A. - When assembling
grip 34, after insertingwiring 21 insidechannel 20 and fixingconnector 31 toportion 5 and to wiring 21,casing 46 is inserted inside cavity 7 through opening 39 and parallel to direction B so as to pressconnectors wall 41. - In a variation not shown,
wall 41 is formed in one piece with a portion ofcasing 46, so thatopening 39 is closed simultaneously with insertion ofcasing 46 inside cavity 7. - In a further variation not shown,
wiring 21 andconnector 31 are co-molded integrally withgrip - The Figure 3 variation relates to a handle 1 comprising a
grip 54, the component parts of which are indicated, where possible, using the same reference numbers as forgrips - Antenna 24 is housed in a
casing 56, which differs fromcasings wiring 21, which is connected electrically toantenna 24 withoutconnectors -
Grip 54 is co-molded in one piece, i.e. by placingcasing 56 and wiring 21 inside the mold ofgrip 54, and then injecting the plastic material aboutcasing 56 and wiring 21, without forming any openings or, therefore, respective closing walls or plugs. - Casing 26, 46, 56 of handle 1 therefore protects
antenna 24 from external agents, such as dust or damp, and from stress produced by theuser gripping portion 5, particularly whenportion 5 is flexible. - In the case of
grips casing grip 54, this itself defines a further one-piece, airtight casing for also preventing entry of external agents. - Moreover,
grips aligned connectors walls 11, 41 being simply pressed in to closerespective openings - Clearly, changes may be made to handle 1 as described and illustrated herein without, however, departing from the scope of the present invention.
- A sensor other than
antenna 24 may be provided to detect the presence of the user and/or to recognize a user-carried identification card; and/or the casing may be other than parallelepiped-shaped, as indicated by way of example. -
Casing 56 need not necessarily be airtight, and/or electric connecting members differing from those described and illustrated may be provided. In particular, a connector may be provided at the outlet ofwiring 21, in particular, co-molded withportion 13.
