The specific embodiment
Target of the present invention is an inertia-activated mechanism, and this device can be used for any automotive door handlebar device, to resist the power of being used to that multiaxis line automobile is collided and caused.With reference to figure 1, Fig. 1 represents an illustrative door knob device 100, and this device comprises according to the inertia-activated mechanism 101 of one embodiment of the invention and a door knob 102.Inertia-activated mechanism 101 can be installed in the existing product door knob, and surrounding environment is changed very little even do not have change, also can be installed in the custom-designed door knob.
As discussed below, in automobile collision process, when having applied a power, comprise the power of the multiaxis line collision of colliding as overturning, inertia-activated mechanism 101 makes the door latch apparatus of door knob device 100 stop door to be thrown off.
With reference to figure 2-8, exemplary inertia-activated mechanism 200 comprises shell 201, and locking plate is locked sword 203 in other words, spring 205, rope bar (cable) 207 and the weight component parts (weight component) 209 with eccentric weight (weight) 210.Locking plate 203, spring 205, rope bar (cable) 207 and weight component parts 209 can be that single component parts also can fit together.These component parts are installed in (Fig. 2) in the shell 201, and shell 201 is arranged in the door latch apparatus body, as represented in Fig. 5 and 6.Locking plate 203 and rope bar 207 can move in shell 201; But motion is subjected to the restriction of spring 205, as to be discussed below.
Shell 201 is configured to be installed in the existing product door knob (as door knob 102) or puts into custom-designed door knob.Shell 201 comprises that is passed the hole 218 that body skin extends.Hole 218 has been defined conical end and has been used to admit locking plate 203, spring 205 and rope bar 207.The present invention is not subjected to the restriction of shell 201 shapes and structure.Therefore shell can have other shape and structure, as Fig. 9 and 10 represented embodiment explanations, will discuss below.Shell 201 also comprises a hole 221 of passing its sidewall.The protrusion 212 that can pivot eccentric wheel 211 is admitted in hole 221, will discuss to this below.
With reference to figure 3, rope bar 207 is pasting locking plate 203 and weight component parts 209, and it is made by flexible material in one embodiment.Locking plate 203 is inserted casting (insertmolded) on rope bar 207 1 ends in an illustrative example.Weight component parts 209 and weight 210 are crimped or are fixed on the other end of rope bar 207.Weight 210 is parts of weight component parts 209 and is accentrics with respect to the axis of rope bar 207, just in time do not offset so that guarantee power in the collision process.That is to say that as the following stated, in the collision process, when weight component parts 209 outwards moved and leaves shell, eccentric weight 210 made the weight component parts directly outwards move with an angle in other words and leave with non-.The weight component parts roughly be tubulose and conical end section 216 arranged, conical end section 216 matches with the cone shaped opening in the hole 218 of shell 201.Rope bar 207 passes spring 205, and spring 205 can be a spiral spring.
The shape of locking plate 203 roughly is flat and defines otch opening 204 in other words, otch 204, as described below, be placed in around the protrusion 212 that can pivot eccentric wheel 211, freely rotate under the situation of non-collision to allow pivoting eccentric wheel.As known to a person skilled in the art, can pivot eccentric wheel 211 and operably be connected in door latch apparatus.When eccentric wheel 211 rotates, because the action of door knob, eccentric wheel 211 will make and allow door latch apparatus to unclamp in other words thereby open car door.To explain more fully below, under the collision situation, the narrow slit 214 in the locking plate 203 engagement protrusions 212 can pivot eccentric wheel 211 rotations to stop, thereby stops the opening door operation of door latch apparatus.
More particularly, in operation, because the eccentric structure of weight component parts 209, match with motion with respect to shell, the door latch apparatus of door knob is limited to open in multiaxis line automobile collision process.Specifically, the elastic force of spring 205 is limited in the initial position with weight component parts 209, that is to say, weight component parts 209 touch shell 201.When a bigger power (colliding corresponding to automobile) is added on the weight component parts 209 thereby make component parts 209 motions, weight constituent 209 will leave shell 201 and overcome the elastic force of spring 205, thereby make rope bar 207 that locking plate 203 is moved into latched position.When being positioned at latched position, locking plate 203 will be arranged in the narrow slit 214 of the protrusion 212 that is formed on eccentric wheel 211.This will stop eccentric wheel 211 to rotate, thereby stop door latch apparatus to throw off and stop door to open.When not having other masterpiece to be used on the weight component parts 209, weight component parts 209 will turn back to the initial position by the elastic force of spring 205.Allow the door latch apparatus normal operation of door knob in this position.
In other words, in the collision process, generally greater than the elastic force of spring 205, elastic force makes weight component parts 209 touch shell 201 to the crash force that causes thus.Weight component parts 209 will outwards be moved and left shell 201 by the round taper hole in the shell 201 218.Therefore weight component parts 209 spurs locking plate 203 by this way, and promptly locking plate 203 is engaged on the narrow slit 214 in the protrusion 212 that can pivot on the eccentric wheel 211.When such location, can pivot eccentric wheel 211 can not rotate, thereby stops bolt to be opened.In general, the weight component parts will move in the collision process, thereby make locking plate motion and eccentric wheel is locked in the position that stops car door opening.In addition, in the collision process, if rope bar 207 has flexibility, weight component parts 209 moves at a certain angle with respect to shell.The angular movement that is caused stops locking plate 203 to turn back to permission can pivot the position that eccentric wheel 211 rotates.
When automobile is motionless in other words when wishing to open the door (when automobile is not absorbed in the collision state) otch in the locking plate 203 in other words opening 204 be positioned at the protrusion 212 that can pivot on the eccentric wheel 211 and narrow slit 214 around.In this configuration, can pivot eccentric wheel 211 turns to allow bolt to be drawn back, so door can be opened.When unclamping, door knob make spring 213 door knob 102 turn back to its off position.
In an illustrative embodiment, shell 201 defines a round taper hole 218.The trochoidal surface of this shape and weight component parts 209 makes the weight component parts not crooked in the collision process.Trochoidal surface is also guaranteed the motion of weight component parts 209 in the collision process.And trochoidal surface helps protection rope bar 207 not frayed.
As mentioned above, in an illustrative embodiment, in dead position, weight 210 is accentrics for the longitudinal axis of rope bar 207.This will guarantee that power is not just in time offset (promptly not cancelling each other) in the collision process, may make locking plate motionless if really just in time offset, thereby allow to pivot eccentric wheel 211 rotations and door is opened.In other words, so because the eccentric weight 210 multiaxis line power cause of colliding of must moving can not cancelled each other in the collision process, thereby make locking plate 203 motions, so that eccentric wheel 211 is locked on the due position.
With reference to figure 9 and 10, these two inertia-activated mechanisms 400 of scheming expression according to another embodiment of the present invention.Inertia-activated mechanism 400 comprises that a locking plate locks 405, one excellent 407, one eccentric weight 409 of bell shape weight part of 403, one rope bars of 401, one springs of sword and a shell 411 in other words.Be similar to other embodiment, locking plate 401 comprises an otch 402, and after the assembling, otch 402 is positioned at around the protrusion 212 that can pivot eccentric wheel 211, and is just as explained above like that.With reference to figure 9, in Fig. 9 shell 411 on casing half dismantled, excellent bell shape weight part 407 has conical section 413, conical section 413 matches with the round taper hole 415 that shell 411 forms basically.
In this embodiment, locking plate 401 and excellent bell shape part 407 inserted casting (insert molded) on rope bar 405, makes locking plate 401, and excellent bell shape part 407 can be pulled down from module when spring 403 and rope bar 405 fit together.But weight 409 crimping are in place or be fixed on the rope bar 405.
The function of inertia-activated mechanism 400 is same as the previously described embodiments.That is to say that during non-hitting, the protrusion 212 that can pivot eccentric wheel 211 can freely rotate in the otch 402 of locking plate 401.Under the collision state, because weight 409 motions are also left shell 411, so the weight 409 that is connected on the locking plate 401 by rope bar 405 will spur locking plate 401, thereby make locking plate 401 mesh the narrow slit 214 that is positioned on the protrusion 212 that can pivot eccentric wheel 211.In this state, in the collision process, will stop to pivot eccentric wheel 211 rotations, thereby stop door to be opened.After the collision, the elastic force of spring 403 is thrown off locking plate 401 and the narrow slit 214 on the protrusion 212 and is turned back to the initial position, thereby allowable offset wheel 211 freely rotates and allow door to be opened.
Figure 10 represents excellent bell shape part 407 and weight 409 position with respect to shell 411.Shell 411 comprises two half-shells, each half-shells all has some mounting holes 417, these holes permissions link together two half-shells with fastener or analogue and are connected on other structure, the component parts of inertia-activated mechanism 400 is disposed in the half-shells, and casing half places top to form shell 411 in addition.In this embodiment, two half-shells are identical basically and can exchange.As shown in Figure 10, a half-shells comprises that reception can pivot the opening 419 of the protrusion 212 of eccentric wheel 211.Inertia-activated mechanism 400 is configured to be installed in the existing product door knob (for example door knob 102), perhaps can be contained in the custom-designed door knob.
