Technical field

The present invention relates to the car door release handle assembly of vehicle, comprise the inertia with retention element and stop sub-component, described retention element is by mistake opened when clashing into for preventing the car door of vehicle.

Background technology

The vehicle door latch assembly of vehicle often comprises a door handle lever, is pulled away from car door to run bolt lock mechanism and opening car door.When the crash such as such as colliding, especially produce a crash perpendicular to the impact force vector of automobile side, the acceleration of vehicle on side force vector direction can cause car door (adding the other parts of vehicle) to accelerate away from door handle lever due to the inertia of door handle lever.This crash is generally made up of two stages: boost phase and deformation stage.

Boost phase corresponds to a period of time started with initial shock.Be typically about the duration of 40 milliseconds during this period of time but duration of about 300 milliseconds can be extended to, at this moment, a release handle assembly in impingement region can stand relatively high acceleration, and the relative high acceleration force be associated with the main lateral movement of Vehicular door therefore produced.This can produce and pull with the similar relative motion of opening car door with to door handle lever.

Then during the deformation stage produced after boost phase, vehicular sideview structure damage by pressure and be out of shape occur in be subject to impact impact region in.Period at this moment, the acceleration of vehicle door latch assembly is progressively reduced to zero in a way.But, depend on specific crash parameter, during deformation stage, still there is the possibility making the car door opening of vehicle.Further, the car door of vehicle has in the event of the boost phase of prolongation can may open at the end of boost phase at some.

In order to by by the minimizing possibility clashing into the car door opening caused unintentionally, the car door release handle supplier of vehicle have developed the inertia barrier structure sub-component being not intended to motion of preventing and being subject to clashing into release handle assembly and/or the car door opening actuator caused by vehicle.These sub-components start (activate) between position of rest and blocking position, wherein at position of rest, car door (if function permission) is opened by operation release handle assembly, and at blocking position, the opening movement of car door is knocked the inertia force prevention of generation.To preventing of the motion of release handle assembly or car door opening actuator, can therefore by completing for based on the acceleration clashed into and the inertia-responsive control be associated with inertia barrier structure sub-component.

Known inertia barrier structure sub-component is configured to have a biased element to turn back to position of rest usually, and this enables car door be unlocked in a conventional manner after not having crash or crash.But, known inertia barrier structure sub-component is general only to work during boost phase, they turn back to its position of rest during deformation stage or after deformation stage usually, this makes release handle assembly to run, and therefore enable occupant leave vehicle and the individual of emergency occurs can easily close to resting on occupant in vehicle.This function can also enable car door by mistake be opened at the deformation stage of crash.

Reduce the car door opening unintentionally after clashing into by inertia barrier structure sub-component as far as possible, this inertia barrier structure sub-component maintains its " stop " position in one selected period after crash stops, instead of makes this sub-component to be back to position of rest.But return the duration that its position of rest extends obstruction may stop car door opening after crash terminates by controlling inertia barrier structure, this can be a potential serious threat concerning the occupant rested in vehicle.

A kind ofly be configured to stop car door opening unintentionally during boost phase and deformation stage, after crash terminates, allow the operation of car door release handle the inertia stop member sub-component of opening car door to be expect simultaneously.

For accompanying drawing, especially in FIG, motor vehicles 10 are only partially shown, and comprise door assembly 12.It is mounted thereto that door assembly 12 has release handle assembly 14, for the ease of opening and closing door assembly 12.Door assembly 12 is also provided with a rearview mirror assemblies 16 and is used for as automotive occupant provides rearward vision.Rearview mirror assemblies 16 is not part of the present invention, therefore hereafter will no longer describe.

As shown in Figure 2, release handle assembly 14 comprises shield face 20 and door handle lever 22.The release handle assembly 14 illustrated just can comprise an example of the release handle assembly of an inertia barrier structure sub-component.Such as, or release handle assembly 14 can comprise other release handle assembly, paddle type or twist mode handle assembly.

Several embodiment sharing same basic configuration and operation of the present invention will be described.This basic configuration is illustrated in figure 3, and it conceptually show in plan view the operation of inertia barrier structure, also relates to the CG the hidden balance that comprises the basic concept of embodiment of the present invention.Inertia barrier structure 140 comprises the inertia barrier structure sub-component (not shown) of part, and it is attached on the standing part of release handle component framework or shield face by hinge connector 144 pivotly with around vertical axis pivotable.Hinge connector 144 departs from the barycenter 148 of inertia barrier structure 140.

Inertia barrier structure 140 is rotatable between the first position of rest 152 and the second bonding station 142 around hinge connector 144.Thus, acceleration force, the part (representing with vector " B ") comprising the large acceleration/field of force of of acting on door assembly can produce a reciprocal masterpiece and be used on barycenter 148, therefore promotes the rotation 150 (counterclockwise to illustrate) of inertia barrier structure 140 to bonding station 142.On the contrary, acceleration force with acceleration force B side in the opposite direction on act on door assembly, inertia barrier structure 140 rotation in the clockwise direction can be promoted.

Bonding station 142, along with its barycenter 148 rotates to position 146 with inertia force vector B and hinge connector 144, can be called as the configuration of " center of gravity hidden " or " CG hidden ".In the CG configuration that this is hidden, inertia barrier structure 140 can keep static until acceleration force fully decays to make inertia barrier structure 140 can turn back to its position of rest 152.A biasing member, such as a helical spring (not shown), can be comprised in inertia barrier structure 140 and turn back to position of rest 152 to promote it.The time cycle that the coefficient of elasticity of biasing member can maintain based on the parameter of the crash of the quality of inertia barrier structure and moment of inertia, design and the CG configuration of hiding is selected.

At position of rest 152, inertia barrier structure 140 can be separated with bellcrank, therefore makes bellcrank to run with opening car door completely.When inertia barrier structure 140 to stop the unlatching of the motion of release handle assembly and car door in the CG configuration of hiding due to crash, this inertia barrier structure 140 can be configured to engage and stop the motion of bellcrank or other release handle mechanism.Inertia barrier structure 140 can maintain in hiding CG configuration 142 until it can rotate to position of rest 152 under the effect of biasing member.When acceleration force vector " B " is not enough to resist the reset force of biasing member, inertia barrier structure 140 be back to position of rest 152 can occur in deformation stage latter stage or after deformation stage.

With reference now to Fig. 4 and Fig. 5, first embodiment comprising above-mentioned hiding CG configuration of inertia barrier structure sub-component 176 is illustrated, a part for composition release handle assembly 160.Release handle assembly 160 comprises shield face (escutcheon) 162 and door handle lever (not shown), is used for operating bellcrank assembly 174.Door handle lever is included in the latch arms (latcharm) 164 of the first end and pivotal arm (pivotarm) (not shown) is rotatably received in pivotal arm housing 170 by pivotal pin (pivotpin) 172.Pull door handle lever that door handle lever can be made around pivotal pin 172 pivotable, the latch arms 164 of mobile release handle assembly 160 outside.Such as, or release handle assembly 160 can by other handle/latch assembly, the latch assembly composition of paddle type or twist mode.

Bellcrank assembly 174 comprises a bellcrank, it transits to the crank finger piece (crankfinger) 166 extended away from supporting pin 184 radial direction from the normally driven end of the first end, crank finger piece is attached to hammerlock 164 (the two is all shown in Figure 10) slidably, to make to work as door handle lever 22 when pulled, crank finger piece 166 outwards movement.Interference finger piece (interferencefinger) 188 extends, in order to become fairly obvious object hereinafter from the second end (being the active end of bellcrank assembly 174 substantially) away from supporting pin 184 radial direction.Bellcrank assembly 174 also comprises a bellcrank counterbalance 182.Bellcrank assembly 174 comprises the supporting pin of an adaptive guiding, and the supporting pin 184 of such as horizontal arrangement is mounted to release handle component framework 186 to realize the rotation of bellcrank assembly 174 around pin 184 longitudinal axis in mode that can be adaptive.Pull door handle lever can outside mobile latch arms 164 and crank finger piece 166, therefore rotate bell crank assemblies 174 to be rotated down interference finger piece 188.

With particular reference to Fig. 5, the inertia barrier structure sub-component 176 comprising inertia barrier structure 178 is rotatably arranged between upper support part 228 and underlying support 230 by pin 246.As shown in Fig. 5, Fig. 7, Fig. 8, upper support part 228 comprises the stop wall (stopwall) 232 of generally linear, and this stop wall extends from upper support part and upcountry terminates at the backstop end (stopend) 234 of plane.Upper support part 228 also has and extends through pin-and-hole 236 wherein to receive pin 246.

With reference to figure 6A-D, inertia barrier structure 178 is erose main bodys, comprises roughly fan-shaped hiding CG counterbalance part 190 (Fig. 6 B) and interference sections (interferenceportion) 192.Counterbalance part 190 comprises top wall (topwall) 194.Interference sections 192 comprises base wall (bottomwall) 196, and this base wall and top wall 194 interval are also in substantially parallel relationship to top wall 194.Sidewall (sidewall) 198 vertically extends substantially between top wall 194 and base wall 196.

Top wall 194 comprises the lower surface 200 being generally plane, is roughly the circular spring cavity 202 being used for holding biasing member at the tip transitions to of top wall 194.Spring cavity 202 is open into narrow, an elongated spring channels 204 in tangential direction, and has the spring opening 214 extended from it.Spring cavity 202 has concentric pin-and-hole 212, and described pin-and-hole extends from spring cavity 202 and extends through top wall 194 and base wall 196.

Below wall 206 extends to arc-shaped from lower surface 200, and portion circumscribes also limits spring cavity 202.Top wall 208 covers the diameter of remaining circumferential section of spring cavity 202 and spring channels 204.Spring cavity 202 and spring channels 204 receive helical spring (not shown).Helical spring coil is received in spring cavity 202.A helical spring arm extends into spring channels 204, and is vertically connected to the finger piece that can be inserted into spring opening 214.Another arm helical spring extends along lower surface 200.

Base wall 196 transits to base wall lug boss (bottomwallprojection) 216 that extend from lower surface 200, generally linear.

Top wall 194 transits to the interference sections 192 extended away from pin-and-hole 212 radial direction.Top wall 194 has smooth top surface 224, and this top surface is directed to and is in substantially parallel relationship to lower surface 200.What extend from top wall 194 is the neck (collar) 220 of the annular coaxial with pin-and-hole 212.Top wall stopper protrusion (topwallstopboss) 218 extends to the radial projection away from pin-and-hole 212 from top surface 224 along top wall 196 and neck 220.Pin-and-hole 212 transverse side walls 198 is to limit the pin groove 222 of elongated, circular passage shape.

Fig. 5 and Fig. 7 shows the inertia barrier structure sub-component 176 at position of rest.In this configuration, inertia barrier structure 178 is promoted with counterclockwise direction by helical spring, as shown in the vector in Fig. 9, can contact (Fig. 8) to make top wall stopper protrusion 218 with backstop end 234.As shown in Figure 5, interference sections 192 can extend below support member 228 usually up.When inertia barrier structure 178 is at position of rest, the barycenter of inertia barrier structure 178 can depart from from axis of rotation (as pin 246).When inertia barrier structure is at position of rest, pull the interference of the rotatable bellcrank assembly 174 of door handle lever 22 and interference finger piece 188 and interference-free part 192.

Fig. 8, Fig. 9 and Figure 10 show the relative position of interference finger piece 188 at boost phase of inertia barrier structure 178 and bellcrank assembly 174.At boost phase, bellcrank counterbalance 182 can produce an outside inertia force, is tending towards rotating bell crank assemblies 174 and abuts against the inside throw crank finger piece 166 of end of latch arms 164.Meanwhile, door handle lever 22 also can produce an outside inertia force.Because door handle lever 22 has higher weight relative to bellcrank counterbalance 182, door handle lever 22 can outwards movement, is tending towards outside mobile latch arms 164 and therefore promotes bellcrank assembly 174 overcoming the inertia force acted on bellcrank counterbalance and rotating.

Meanwhile, inertia barrier structure 178 can overcome the rotation of helical spring bias voltage.Interference sections 192 can rotate towards bellcrank assembly 174 and latch arms 164 simultaneously, and top wall stopper protrusion 218 can move away from backstop end 234, at boost phase, the rotation of interference sections 192 can make inertia barrier structure 178 enter in hiding CG configuration, and this configuration can extend to deformation stage.Thus, inertia barrier structure 178 can be prevented from returning its position of rest, and disturb finger piece 188 can contact with interference sections 192, stop interference finger piece 188 downwards and to inner rotary, therefore stop the rotation of bellcrank assembly 174 and door handle lever 22 in the motion of deformation stage.

At the end of deformation stage, the power produced by helical spring can make inertia barrier structure 178 be back to position of rest, thus can operate release handle assembly 14.

Figure 11-16B shows second embodiment similar with the first embodiment of the present invention, except comprising the barrier structure retention means that extends the duration of CG configuration and the inertia barrier structure joint hidden.The identical label of element identical with the first embodiment in second embodiment identifies, and when except for fully understand the present invention and necessity no longer describe.

Figure 12 shows the inertia barrier structure 178 with barrier structure retention means, comprise a generally linear, be the barrier structure stop part 226 of brick in a way, it upwards extends from the top surface of interference sections 192 along its external margin.The biasing member of a such as spring is not illustrated, and it can be accommodated in spring cavity 202, and except making inertia barrier structure 178 rotate to position of rest, also can support member 228 is upwardly upward by inertia barrier structure 178.

For Figure 13 and Figure 14, framework protrusion (frameprojection) 238 is elongated, the to be with cantilever beam textures extended internally from release handle component framework 186.Framework protrusion 238 end is connected in barrier structure retention means, comprises barrier structure buckle (catch) 180.Barrier structure buckle 180 comprises inclined-plane (inclinedface) 240, and this inclined-plane outwards transits to the concave surface (concavesurface) 242 crossing framework protrusion 238 and extend laterally, and limits recess (recess) 248.Concave surface 242 inwardly transits to the inclined-plane 244 crossing with inclined-plane 240.As described below, what barrier structure buckle 180 and barrier structure stop part 226 were configured to work in coordination is interconnected.

Figure 14 A-B shows the inertia barrier structure sub-component 176 at position of rest.In this configuration, the rotatable bellcrank assembly of door handle lever 22 174 and interference finger piece 188 is pulled and not by the interference of inertia barrier structure 178.

Figure 15 A-C shows at the relative position of boost phase inertia barrier structure 178 with the interference finger piece 188 of bellcrank assembly 174.Identical to first embodiment of the actuating of inertia barrier structure sub-component 176 substantially with above-mentioned at boost phase.Hiding CG counterbalance part 190 can promote inertia barrier structure 178 and rotate into hiding CG configuration.

In the end of boost phase subsequently or in the time cycle of deformation stage, inertia barrier structure 178 can along with interference sections 192 and framework lug boss 238 be on time, rotate in hiding CG configuration fully, thus inertia barrier structure stop part 226 can be advanced along inclined-plane 240 and enter recess 248. as shown in Figure 16 A-B, this motion can promote inertia barrier structure 178 and run downwards towards underlying support 230, overcome the power that biasing member leads downwards, connect stop part 226 and buckle 180 thus.The power that biasing member leads downwards can make inertia barrier structure stop part 226 remain in recess 248, and makes inertia barrier structure 178 after crash terminates, be in stop configuration.

At the end of crash, pull door handle lever 22 that interference finger piece 188 can be made to abut against interference sections 192 to be rotated down, mobile inertia barrier structure 178 makes it depart from from recess 248 to make inertia barrier structure stop part 226 away from framework lug boss 238, therefore makes biasing member that inertia barrier structure 178 is back to position of rest.

For Figure 17 A-C, inertia barrier structure 250 comprises hiding CG counterbalance part 252 and interference sections 254.The CG counterbalance part 252 hidden comprises base wall 258.Interference sections 254 comprises top wall 256.Top wall 256 is combined by sidewall 260 with base wall 258.

Base wall 258 transits to the base wall lug boss 262 of radial arrangement, and top wall 256 transits to the top wall stopper protrusion 264 of radial arrangement.Pin-and-hole 266 extends through top wall 256 and base wall 258 coaxially.High wall (highwall) 268 circumferentially extends around the part in elongated spring channels 204 and coil component spring chamber 202.First barrier structure retention means comprises high wall projection (highwallboss) 270, and this projection is given prominence to downwards from the outward flange corner of high wall 268, and has the inclined-plane 280 radially-inwardly led, and this inclined-plane radially outward transits to parallel surface 282.

The overhead surface of interference sections 254 has the inertia barrier structure stop part 278 of the generally linear upwards extended from it, rotates leave position of rest to engage to limit inertia barrier structure 250 with stop surface 310.Second barrier structure retaining device element comprises the neck 272 of annular, and this neck and pin-and-hole 266 are given prominence to from the overhead surface of inertia barrier structure 250 is vertical with one heart.What open with neck 272 radial separations is the 3rd barrier structure retaining device element, and it comprises semicircular arciform wedge 274, and this arciform wedge has the inclined-plane 276 upwards led.

As shown in figure 21, upper support part 286 has the 4th barrier structure retaining device element and comprises the outstanding arciform tapered wall of semicircle (arcuatewedgewall) 292 downwards, this arciform tapered wall is configured to, when inertia barrier structure 250 is arranged between underlying support 284 and upper support part 286, coordinate with arciform wedge (arcuatewedge) 274.Arciform tapered wall 292 comprises the first inclined-plane 294 and transits to the second inclined-plane 296 by vertical plane 198.Inclined-plane 292,296 is directed to and coordinates with the inclined-plane 276 of arciform wedge 294.Upper support part 286 also comprises stop wall 288 end and is connected to backstop end 290.

As shown in Figure 18 C and Figure 22, underlying support 284 has otch (cutout) 300, this otch extends into underlying support 284 and is limited by the sidewall of cantilever (cantileverwall) 302, and this sidewall transits to plane from arcuation surface (curvedface) 304 and comes and goes surface (planarreturnface) 306.Otch 300 is used to work in coordination with high wall projection 270.

Figure 18 A-B shows inertia barrier structure 250, underlying support 284 and upper support part 286 relative position at position of rest.In the configuration, inertia barrier structure 250 can be promoted in the clockwise direction by helical spring, top wall stopper protrusion 264 is contacted with backstop end 290, therefore further rotating and being oriented in relative to axis of rotation (namely by the center of gravity of inertia barrier structure 250 of inertia barrier structure 250 is stoped, pin 246) optimum position, with the operation making inertia barrier structure comparatively satisfied in crash.In addition, as previously described, inertia barrier structure 250 also can by up towards upper support part 286 bias voltage.

At this position of rest, arciform wedge 274 circumferentially can be separated away from arciform tapered wall 292.Interference sections 254 can below the extending laterally along bellcrank assembly 174 of support member 286 up usually.The barycenter of inertia barrier structure 250 can depart from from axis of rotation towards latch arms 164.Pull door handle lever 22 can run bellcrank assembly 174, and not by the interference of inertia barrier structure 250; Interference finger piece 188 can be rotated down and not contact with interference sections 254.

Figure 19 A-B shows inertia barrier structure 250, underlying support 284 and upper support part 286 relative position at boost phase.At boost phase, inertia barrier structure 250 can overcome the rotation of helical spring bias voltage and interference sections 254 is rotated towards bellcrank assembly 174 and latch arms 164.The inclined-plane 276 of arciform wedge 274 can contact with the first inclined-plane 294 of arciform tapered wall 292 and move along it, and the power overcoming biasing member promotes inertia barrier structure 250 towards underlying support 284 downwards.High wall projection 270 also can be pushed towards the overhead surface of underlying support 284.Interference finger piece 188 can be rotated down to contact inertia barrier structure 250 simultaneously.But by the contact of high wall protruding 270 with the overhead surface of underlying support 284, the motion that inertia barrier structure 250 is downward and the downward rotation of interference finger piece 188 are prevented from.

For Figure 20 A-B, when inertia barrier structure 250 continues to rotate, when arciform wedge 274 is by inclined-plane 294, inertia barrier structure 250 continues to move down.Meanwhile, high wall projection 270 interference finger piece 188 effect under and/or arciform wedge 274 along " falling " in the traveling process on inclined-plane 294 enter (Figure 22) in otch 300, thus stop barrier structure 250 rotate be back to position of rest.When wedge 274 leaves the vertical surface 298 of arciform tapered wall 292, inertia barrier structure 250 can be pushed upwardly, and drives arciform wedge 274 to contact with the second inclined-plane 296.The rotation that inertia barrier structure 250 is back to position of rest can be stoped with the joint of vertical surface 298 by arciform wedge 274, during deformation stage and after deformation stage, continue to realize stop and disturb finger piece 188 and the unlatching stoping operation and the door assembly 12 unintentionally of release handle assembly 14.

At the end of crash, pull door handle lever 22 that interference finger piece 188 can be made to overcome interference sections 154 to be rotated down, downward promotion inertia barrier structure 250 also makes arciform wedge 274 be separated from arciform tapered wall 292, and thus inertia barrier structure 250 can return position of rest under the effect of biasing member.Along with arciform wedge 274 crosses arciform tapered wall 292, high wall projection 270 remains in otch 300, until arciform wedge 274 leaves from arciform tapered wall 292, the motion that barrier structure 250 is downward at this moment can make high wall projection 270 leave otch 300.Inertia barrier structure 250 be back to position of rest with make bellcrank assembly 174 can uncrossed operation time, be necessary second time discharge and pull door handle lever 22.

According to the fourth embodiment of the invention Figure 23-28 shows.Door handle lever 22 comprises support tip 24 and relative lock end 26.As shown in Figure 23, Figure 24, what vertically extend from the support tip 24 of door handle lever 22 is that elongated support arm 28 has uniform section usually, and shown here is common linear.Similarly, what vertically extend from the lock end 26 of door handle lever 22 is that latch arms 30 has and is roughly linear cross section.

Each arm 28,30 inside is end adjacently connected to vertically arranged linear slot (slot) 35,37 respectively at it.Support arm 28 and latch arms 30 are received to in the tubular handle sleeve 56,54 of its complementation respectively slidably, are attached to shield face 20 rigidly.Pull door handle lever 22 arm 28,30 can be moved towards the outside of door assembly 12 slidably from the outer side of vehicle 10.

Away from tie-beam 42 crank end 34 less perpendicular be elongated crank finger piece 38 to downward-extension.Away from tie-beam 42 support tip 36 less perpendicular be elongated support finger piece 40 to downward-extension.Finger piece 38,40 is suitable for connecting slidably with slit 37,35, pulls out door handle lever 22 and transfer arm 28,30 outwards can pull finger piece 38,40 to make door assembly 12.

Pin 46 is tiny, columniform, bar-shaped components, is rotatably supported by rights, and such as, can be supported by the framework of a rigidity or shield face assembly 68, many elements of release handle assembly 14 all can be attached on it.

Approximate mid points away from tie-beam 42 extend and with finger piece 38,40 relative be roughly to project upwards ground, block bellcrank counterbalance 44.Substantially away from tie-beam 42 downwards mid point that is outstanding, that depart from tie-beam 42 in a way and bellcrank counterbalance 44 be barrier structure retaining device element, it comprises the transition projection (translationboss) 50 with the inclined-plane arranged downwards.With this transition protruding 50 adjacent and to be roughly adjacent from it be downwards inertia barrier structure sub-component 52, this sub-component comprises inertia barrier structure 58, and this inertia barrier structure is fixed (Figure 24) by mount pin 60.Mount pin 60 is supported by a pair pillow block (pillowblocks) 122,124, described pillow block is attached to the suitable part of release handle assembly 14 regularly, as rigid frame, sub-component or shield face 20, and be associated with biasing member or back-moving spring 62.Pillow block 124 is configured to have at the end of its inner side the barrier structure retaining device element comprising laterally projecting stop block (stopblock) 126.

With reference now to Figure 25 A-B, inertia barrier structure 58 is erose main bodys, it comprises relative thin, smooth inertia barrier structure plate 70, and this plate has the through neck 72 being roughly annular, and this neck extends vertically through wherein and defines coaxial installation pin-and-hole 74.Inertia barrier structure plate 70 comprises fan-shaped part 76, and this fan-shaped part has tip (apexend) 78 and a relative arcuate end (curvedend) 80.From most advanced and sophisticated 78 laterally extend and with fan-shaped part 76 coplanar be stop part finger piece (stopfinger) 82.Arcuate end 80 defines arcuate wall (arcuatewall) 84, and this arcuate wall transits to the stop part projection (stopboss) 86 being roughly and upwards extending.Install pin-and-hole 74 can receive elongated, be roughly columniform mount pin 60, as described below, pin 60 is supported by suitable mode, and the axis of rotation being used for inertia barrier structure 58 is extended jointly around the longitudinal axis with pin 60 rotates.

Through neck 72 comprises freely part (freeportion) 90 of annular, this freely partly extends from the first lateral vertical of inertia barrier structure plate 70 substantially, and barrier structure retaining device element comprises bonding part (engagementportion) 92, this bonding part to extend and coaxial with free part 90 from the lateral vertical that the second-phase of inertia barrier structure plate 70 is right substantially.The center of gravity of inertia barrier structure 58 is positioned on inertia barrier structure plate 70, the axis of rotation that lateral run-out associates with mount pin 60.

Bonding part 92 comprises and is roughly columniform turntable (turret) 94, and this rotating bars tangentially transits to the turntable projection (turretprojection) 100 of rectangle in a way substantially.Arc diapire (lowwall) 96 covers turntable 94 along the circular arc arranged towards stop part finger piece 82.First high wall 98 covers remaining part of turntable 94, and transits to the second high wall 102 covering turntable projection 100.The diapire 96 and the high wall 98 that cover turntable 94 define the spring cavity 110 coaxial with installing pin-and-hole 74.The the second high wall 102 covering turntable projection 100 defines spring channels 104.Spring opening 106 extends into turntable projection 100 from the bottom of spring channels 104.What cover high wall 98,102 at its transition portion is linear barrier structure projection 108.

Spring cavity 110 and spring channels 104 are configured to receive biasing member or helical spring 62, and this spring has the coil (coil) 116 be suitable for around mount pin 60.What the first end away from coil 116 tangentially extended is contact arm (contactarm) 112, and this contact arm is vertically connected to touching finger (contactfinger) 118.The second end away from coil 116 tangentially extends and what angularly depart from contact arm (contactarm) 112 is barrier structure arm 114, and this arm is vertically connected to barrier structure finger piece 120.When spring 62 to be positioned in spring cavity 110 and around mount pin 60 time, barrier structure finger piece 120 is adapted to be and inserts spring opening 106.In this configuration, contact arm 112 can with extend across diapire 96.

With reference to figure 26A, the sweep between contact arm 112 and touching finger 118 can be resisted against on shield face 20, thus inertia barrier structure 58 can be rotated counterclockwise and is pushed, as represented by curved arrow " A " in Figure 25 B.

Figure 26 A-B shows inertia barrier structure 58 and bell crank actuator 32 with the relative position of configuration of stopping.The mount pin 60 supported by pillow block 122,124 rotatably hangs inertia barrier structure 58.Back-moving spring 62 can be propulsive inertia barrier structure 58 and be rotated, thus stop part finger piece 82 is contacted with shield face 20, makes inertia barrier structure 58 stablize thus in place, and stop part protruding 86 is separated with transition projection 50.In this configuration, pull door handle lever 22 bell crank actuator 32 can be caused to rotate around bearing pin 48 with opening car door assembly 12, thus activate bellcrank, and transition projection 50 is onwards rotated away from inertia barrier structure 58.Therefore, inertia barrier structure 58 can not move.

Figure 27 A-B shows inertia barrier structure 58 and the relative position of bell crank actuator 32 at the boost phase of crash.In this stage, bellcrank counterbalance 44 and transition projection 50 can outwards move towards shield face 20, thus crank actuator 32 is rotated around bearing pin 48, and finger piece 38,40 is pushed inwardly, and door handle lever 22 is remained on closing of the door position.Meanwhile, the rotatable stop part finger piece 82 that makes of inertia barrier structure 58 moves inward away from shield face 20 and stop part projection 86 outwards movement.Barrier structure projection 108 can upwards move along the stop block 126 of pillow block 124, and finally leaves stop block 126, as shown in fig. 27 a.

With reference now to Figure 28 A-B, if cause bellcrank counterbalance 44 and transition projection 50 to move inward away from shield face 20 in deformation stage acceleration force, the inclined-plane of the transition projection 50 moved inward equally can be taken to and contact with arcuate wall 84, promotes bell crank actuator 32 thus and returns its position of rest.The continuation movement of transition projection 50 can promote arcuate wall 84 and slide along the inclined-plane of transition projection 50, and promotes inertia barrier structure 58 and slide towards pillow block 124 along mount pin 60.The barrier structure projection 108 having left stop block 126 can move along stop block 126 towards pillow block 124, until barrier structure protruding 108 contacts with barrier structure surface 130.In this configuration, due to stop part protruding 86 and the joint of transition projection 50, inertia barrier structure 58 and bell crank actuator 32 can not rotate and return its position of rest.

Return its position of rest because inertia barrier structure 58 and bell crank actuator 32 are blocked for rotation, door handle lever 22 can be stopped moving and opening car door assembly 12.When acceleration force disappears, back-moving spring 62 can promote inertia barrier structure 58 towards to its position of rest, wherein stop part finger piece 82 contact with shield face 20 and stop part projection 86 away from transition projection 50.The power being tending towards that inertia barrier structure 58 is rotated that back-moving spring 62 applies can promote arcuate wall 84 and upwards advance on the inclined-plane of transition projection 50, until barrier structure projection 108 is left barrier structure surface 130 and slided along stop block 126.Door assembly 12 can keep closing clashing into the boost phase caused, but after crash terminates, when acceleration disappears, door assembly can be unlocked.

Following reference diagram 29A to Figure 29 E, it is depicted as another interchangeable embodiment of the inertia barrier structure sub-component for Vehicular door release handle mechanism.Except what enumerate, comprise the handle assembly of inertia barrier structure sub-component below, basic identical about the foregoing description of other embodiments with the present invention.

About remaining part following in the embodiment of the present invention as shown in Figure 29 A to 31D, can be regarded as Digital ID relevant in figure only relevant with this embodiment, and therefore have nothing to do with the Digital ID in other figure.Can be regarded as equally, term " top ", " top ", " below ", " bottom ", unless stated otherwise, all only relative to the referential limited in figure, instead of the relation completely vertical with horizontal plane.On the contrary, it will be understood by those skilled in the art that, location in the present invention's this embodiment disclosed in it can be changeable, to adapt to different door handle assemblies, as long as such full terms can be met: barrier structure is translationally removable with rotation mode in the mode in mode described below and other embodiments several of the present invention, with the operation of interfere with vehicles door handle assembly as required.

According to the embodiment of Figure 29 A to 29E, inertia barrier structure sub-component comprises the inertia barrier structure 350 be associated with release handle framework 400, and this barrier structure 350 has the center of gravity (being represented by the dotted line R in Figure 29 A and Figure 29 B) departing from axis of rotation.As mentioned below, barrier structure 350 can (by the arrow A in Figure 29 A and Figure 29 B between position of rest (shown in Figure 29 A and D) and bonding station (shown in Figure 29 B and E), in direction of rotation ₁and A ₂represent) and translation direction (by the arrow B in Figure 29 A and Figure 29 B ₁and B ₂represent) motion, wherein the actuating of release handle (not shown) can not be stoped to realize the operation of vehicle door latch at position of rest barrier structure 350, and stop the actuating of vehicle door latch at bonding station barrier structure 350.

More specifically, barrier structure 350 comprises interference sections 352, its embodiment above-mentioned with the present invention is consistent, and contact with the interference sections 610 of bellcrank 600 with the bonding station of barrier structure 350 at bellcrank assembly, therefore the movement of the rotation of bellcrank assembly and door handle lever is stoped (and therefore, stop the unblock of Vehicular door, according to the present invention, unblock by latch bar (latchrob) 700, bellcrank 600 is linked to vehicle door latch to realize (not shown)).

As shown in Figure 29 A to 29C the best, barrier structure 350 comprises erose main body, and this main body is arranged on the door handle framework 400 between upper support part 410 and underlying support 420 movably.Barrier structure 350 is movably mounted on pin or axle 500, and this pin or axle are fastened to the framework 400 extended between support member 410 and underlying support 420 up.Pin 500, exemplarily, takes the form similar with aforesaid embodiment, and is received by the axially aligned opening 357 and 358 be limited in barrier structure 350 main body.Should be appreciated that pin 500 defines the rotation R of barrier structure 350.

Similar with other embodiments disclosed herein, barrier structure 350 comprises counterbalance part 351, which defines the center of gravity departed from of barrier structure, and this center of gravity, when responding as clashed into the acceleration force caused, makes barrier structure produce motion.According to the present embodiment, visible counterbalance 351 can take form be away from barrier structure rotation R radial direction extend erose piece.This counterbalance 351 can have or not have the hiding CG configuration as described in other embodiments of the present invention.As long as have employed hiding CG to configure, should be interpreted as from aforesaid embodiment, at the bonding station of barrier structure 350, the rotation R of the center of gravity of barrier structure and the vector of acceleration force and barrier structure 350 in line.According to the present invention, it will be understood by those skilled in the art that counterbalance 351 is configured and is arranged to restriction center of gravity, this center of gravity, when responding as clashed into the acceleration force caused, makes barrier structure 350 produce rotary motion.

The interference sections 352 of barrier structure 350 is configured to, when barrier structure 350 is at its bonding station (Figure 29 B), extend to the travel path of bellcrank 600 or other displaceable elements of release handle.On the contrary, when barrier structure 350 is at position of rest time (Figure 29 A), barrier structure 250 permission startup release handle assembly (and, according to shown embodiment especially, activate bellcrank 600).

Barrier structure retention means is configured at least one of release handle component framework 400 and barrier structure 350.In the embodiment illustrated, barrier structure retention means comprises each of lug boss on one that is configured in release handle component framework 400 or barrier structure 350, and comprising the recess being arranged in release handle framework 400 or barrier structure 350 on another, this lug boss is received in this recess at least in part at the bonding station of barrier structure 350.Embodiment more specifically according to Figure 29 A to Figure 29 E, this barrier structure 350 at an upper portion thereof end comprise away from rotation R radial direction extend shelf or shoulder 355.Pin joint is received opening 358 and is restricted to through shelf portion 355, best as shown in Figure 29 C.Shelf or shoulder 355 define the overhead surface 356 being roughly plane, and this overhead surface is arranged to relative with the lower surface 411 of upper support part 410.What extend from overhead surface 356 towards relative upper support part 410 is the engagement member 357 be configured in barrier structure 350.Engagement member 357 is sized to be limited at otch on the underlying surfaces 411 of upper support part 410 or recess 412 receives, and hereafter will continue to describe.As shown in the figure, otch or recess 412 are limited on upper support part 410, open with the location interval of the mating component 357 of barrier structure 350 when position of rest.More specifically, otch or recess 412 are located along the rotate path of barrier structure 350, and thus, as described below, when barrier structure 350 is at bonding station, engagement member 357 is received in recess 412.

Underlying support 420 comprises arcuation cut out portion or recess 421, and the inferior portion 360 of barrier structure is received at its position of rest and enters this recess (as shown in Figure 29 A and 29D).Recess 421 is partly limited by sidewall 422, this side wall surface to and adjoiner at the relative contact 353 of the barrier structure 350 of position of rest, therefore stop barrier structure 350 from the counter-rotating of position of rest (namely in arrow A ₂direction).

Between the underlying surfaces and underlying support 420 of interference member 352, barrier structure 350 defines chamber or otch 361, in order to place biased element or component 385.Be contained in and be connected to each in barrier structure 350 and (by outstanding leg 385a) framework 400 with its relative end therebetween, and receiving pin or axle 500 further, barrier structure 350 is biased into its bonding station in mode hereinafter described by described pin or axle by biased element 385.In the embodiment illustrated, biased element 385 comprises a helical torsional spring, but can be expected that other biased element, comprises the spring of other types, also can replace.According to shown embodiment, at the position of rest (Figure 29 A and 29D) of barrier structure 350, helical torsional spring bears the compression in longitudinally (i.e. the direction of rotation R), and can be understood as barrier structure 350 up (in arrow B ₁direction) bias voltage moves to its bonding station.On the other hand, when barrier structure 350 is at bonding station, helical torsional spring is expanded to it in arrow A from position of rest to the rotary motion of bonding station by barrier structure 350 ₂the point that direction is biased, and be therefore propulsive barrier structure 350 and return position of rest.Accordingly, can be understood as, at the position of rest of barrier structure 350, the torsionspring in shown embodiment is not torsionally be loaded (but can be understood as, according to shown embodiment, barrier structure freely can be pushed to bonding station).

Because acceleration force acts in the center of gravity of barrier structure, barrier structure 350 is both rotatable (in arrow A ₁direction) again can translation (in arrow B ₁direction) move to bonding station (Figure 29 B and 29E) from position of rest (Figure 29 A and 29D).More specifically, acceleration force causes barrier structure 350 in arrow A ₁direction rotate.When barrier structure 350 rotates, engagement member 357 is moved towards otch 412 by the position of rest contacted from it with the underlying surfaces 411 of upper support part 410 rotatably.When engagement member 357 leaves the underlying surfaces 411 of support member 410, biased element 385 is in arrow B ₁direction upward support member 410 translationally promote barrier structure 350, therefore make engagement member 357 enter recess 412 completely.In this position, best as shown in Figure 29 B and E, interference sections 352 is disposed in bellcrank 600 (this crank under normal operation, move downwardly to from the position shown in Figure 29 A to 29E and exceed the point of interference sections 352 when bonding station) travel path, and more specifically, with interference sections 610 in the face of and offset to stop normally moving downward of bellcrank 600.

Due to barrier structure retention means (such as, the engagement member 357 of the cooperation shown in the present embodiment and otch 412), barrier structure 350 by maintenance at bonding station, until barrier structure retention means from release handle component framework 400 and barrier structure 350 at least one be separated.More specifically, visible engagement member 357 is maintained in recess 412, and reason had both been biased element 385, and it is in arrow B ₁translation direction promote barrier structure to bonding station, be also engagement member 357 and the relative bonding of the end wall (endwall) 413 of recess 412, which prevent barrier structure in arrow A ₂the rotary motion (being namely back to position of rest) in direction.

Barrier structure retention means can be realized by operation release handle assembly from the separation of at least one release handle component framework and barrier structure.More specifically, by with mode similar according to a further embodiment of the present invention, pull door handle lever (not shown) that bellcrank assembly is rotated down by enough power, make the interference sections 352 of interference sections 610 against barrier structure 350 of bellcrank 600, therefore make barrier structure 350 in arrow B ₂direction move downward.This motion will make engagement member 357 depart from recess 412.When engagement member 357 leaves otch or recess 412, and particularly, when leaving end wall 413, the torsional bias of helical torsional spring 385 will be propulsive barrier structure 350 in arrow A ₂direction rotate, and be thus back to position of rest.Meanwhile, the continuing of bellcrank 600 moves downward the contact by by interference sections 352 and 610, makes barrier structure in arrow B ₂direction move downward, to compress helical torsional spring 385, until when barrier structure rotate completely be back to position of rest time, because interference sections 352 is moved to the path leaving interference finger piece rotatably, to prevent between interference sections 610 with interference sections 352 further coordinates.Therefore, can be understood as, under the acting in conjunction of the actuating of door handle lever and the bias voltage of helical torsional spring, barrier structure engagement member 357 is separated from recess 412, and meanwhile, barrier structure 350 is back to position of rest.

It is expected to, and according to aforementioned should easy understand, barrier structure 350 can be configured by other engagement member with the joint of upper support part 410 and realize, and comprise, rearranging between Various Components as escribed above realizes.

Following Figure 30 A and 30B, shows the embodiment that another is alternative, its all great in identical with the embodiment of Figure 29 A to 29E, unless otherwise mentioned.More specifically, the feature of the embodiment of Figure 30 A and 30B is the ramp portion 414 ' be arranged in the recess 412 ' of upper support part 410 ', in order to when barrier structure 350 ' is moved into and leaves bonding station (Figure 30 B) provide a resistance area for lug boss 357 '.More specifically, ramp portion 414 ' defines the transitional surface between the soffit 411 ' of support member 410 ' and recess 412 '.

According to this embodiment, the location of resistance area 414 ' is such, is different from the end wall 413 in the embodiment of above-mentioned Figure 29 A to 29E, and when engagement member 357 ' is in recess 412 ', resistance area 414 ' not exclusively stops barrier structure 350 ' in arrow A ₂the rotary motion in direction.On the contrary, tool angled surperficial 414 ' is directed to only opposing and therefore slows down the rotary motion that barrier structure 350 ' returns its position of rest (Figure 30 A).Can be regarded as from this manual, consider the biasing force of helical torsional spring 385 ' or other biased elements, the gradient of resistance area 414 ', length and/or surface profile will be such as like this: stop barrier structure 350 ' to return its position of rest, until barrier structure is in its bonding station by the no longer necessary moment; Such as, until the deformation stage of shock or collision has arrived the unexpected door handle assembly that activates by the no longer possible stage.According to aforementioned, therefore, the embodiment of Figure 30 A and 30B can be understood to, by the effect of helical torsional spring 385 ' or other biasing members, allows barrier structure 350 ' to automatically return to position of rest after crash.

Figure 31 A to 31D describes and comprises and release handle component framework 400 " the inertia barrier structure 350 that is associated " another embodiment substituted of inertia barrier structure sub-component.Barrier structure 350 " all great in all identical with the embodiment of Figure 29 A-29E, unless otherwise mentioned.

Barrier structure 350 " be arranged on movably be fixed to framework 400 " and support member 410 up " and underlying support 420 " between the pin that extends or axle 500 " on.Pin 500 ", exemplarily, take the form similar with aforesaid embodiment, and be limited at barrier structure 350 " axially aligned opening 357 in main body " and 358 " receive.Should be understood to, pin 500 " define barrier structure 350 " rotation R.

Visible barrier structure 350 " lack engagement member 357,357 ' in the embodiment of Figure 29 A to Figure 30 B, visible upper support part 410 simultaneously " also lack recess in above-mentioned embodiment or otch 412,412 '.On the contrary, these overhead surface of barrier structure are smooth surfaces with the relative underlying surfaces of upper support part substantially.

Replace the engagement member in aforesaid embodiment, the barrier structure 350 in the embodiment of Figure 31 A to 31D " define contiguous underlying support 420 " longitudinal contact surface 353 ".Correspondingly, underlying support comprises the otch of scalariform, and this otch comprises support member 420 from below " overhead surface 422 " extend to the first recess 421 of first degree of depth ".First degree of depth of the first recess is by ladder 423 " position limit, this ladder comprises overhead surface 424 " and sidewall 425 ", this side wall transition is to from overhead surface 424 " extend to the second recess 426 of second degree of depth ".Overhead surface 424 " and ladder 423 " sidewall 425 " between combination define the first recess 421 " and the second recess 426 " between Transition edges.Further, otch defines overhead surface 422 " and overhead surface 424 " between sidewall 427 ", the best is as shown in figure 31b.

, barrier structure 350 same with aforesaid embodiment " in interference sections 352 " underlying surfaces and underlying support 420 " between define chamber or otch 361 ", be used for arranging biased element or component 385 " (see Figure 31 C).According to the embodiment of Figure 31 A to 31D, biased element 385 " pass through in arrow B ₁direction upwardly barrier structure and leave and the second recess 426 " joint, by barrier structure 350 " be biased into position of rest, and therefore make the overhead surface of barrier structure contact with the relative underlying surfaces of upper support part.
