The specific embodiment
Fig. 1 shows the mechanism 1 for transport vehicle according to an embodiment of the invention.
Mechanism 1 especially comprises frame 2 and multiple building blocks of function 4, and each building blocks of function is set to carry out predetermined technical functionality.
For example mechanism 1 can corresponding to transport vehicle such as relative seat bottom for adjusting angularly the chair mechanism of the mechanism of seat-back position.According to this example as described in Fig. 5 to Fig. 7, building blocks of function is also corresponding to being pivotally mounted in frame the bolt with respect to the position of the chair back of seat bottom with locking or release.Mechanism 1 can be corresponding to being designed on equipment vehicle, the especially another kind of mechanism in Vehicular occupant railway carriage or compartment.
Mechanism 1 comprises multiple cams 6.Cam 6 is coaxial.Cam 6 is by radially stacked, makes so like this them allly work at grade.For example, by cam 6 radially stack each other.
Cam 6 is rotatable with respect to frame 2 between nominal position and actuated position, as shown in Fig. 1 and Fig. 3-6, in nominal position, by supporting the independent building blocks of function 4 in multiple building blocks of functions 4, make each cam 6 along with the first hand of rotation (be cw according to the example of Fig. 1 and Fig. 4, conter clockwise according to the example of Fig. 5 to Fig. 7) the second contrary hand of rotation (is conter clockwise according to the example of Fig. 1 and Fig. 4, cw according to the example of Fig. 5 to Fig. 7) stop, on actuated position, as shown in Figure 2, the building blocks of function 4 that wherein each cam 6 supports in nominal position with it is (but they can support another as the building blocks of function 4 described in Fig. 7) that separate.
It should be noted in the discussion above that without the rotation that carrys out guide cam 6 by frame 2.
Example as shown in Fig. 1 and Fig. 7, nominal position can be corresponding to the stable equilibrium position of cam 6.
As shown in Fig. 1 and Fig. 3 to Fig. 6, in nominal position, each cam 6 has the angle stroke play with respect to other cams 6, and making so like this each cam 6 be independent of other cams 6 is rotatable along the first hand of rotation from nominal position.This is all actv. for master cam 6 and auxiliary cam 10.
It should be noted in the discussion above that the quantity of cam 6 can be different from the quantity of building blocks of function 4.Therefore, for example cam 6 can be worked simultaneously together with two building blocks of functions 4.
In cam 6, mechanism 1 comprises master cam 8 and at least one auxiliary cam 10.Master cam 8 is corresponding to master cam, and the motion of master cam 8 restricts the motion of auxiliary cam 10.In fact master cam 8 is designed to make directly or indirectly auxiliary cam 10 to rotate.In other words,, for making all auxiliary cams 10 pivotables, making master cam 8 by predetermined rotating part is enough along the first hand of rotation rotation.
If mechanism 1 comprises N auxiliary cam 10, can they be carried out stacking with N continuous horizontal; Therefore can reference levels 1, the cam of level 2, level 3, horizontal N, remove from their shared rotation axiss.
Therefore, according to the example of Fig. 4, mechanism 1 comprises four cams 6, this cam 6 comprises master cam 8 and three auxiliary cams 10, this auxiliary cam 10 comprises the most close master cam 8 of level 1 auxiliary cam 10(), level 3 auxiliary cam 10(are away from master cam 8), and level 2 auxiliary cam 10(are between level 1 auxiliary cam 10 and level 3 auxiliary cams 10).
Mechanism 1 also comprises the first return mechanism such as spring 12, such as coil spring (only showing in Fig. 5 for better illustrating accompanying drawing).Spring 12 can make master cam 8 turn back to nominal position; This is contrary along the rotation of the first hand of rotation with master cam 8.Spring 12 can comprise the other end that is attached to one end of frame 2 and is attached to master cam 8.
Mechanism 1 also comprises for example the second return mechanism such as spring 14, and moment of torsion is applied on each auxiliary cam 10, this moment of torsion is designed to keep this each auxiliary cam at building blocks of function 4 corresponding to nominal position upper support.Spring 14 can be corresponding to Compress Spring.
According to the example of Fig. 1 and Fig. 2, auxiliary cam 10 is connected to master cam 8 by spring 14.It can be connected to frame 2 by auxiliary cam 10 alternatively.
In the time that mechanism 1 comprises multiple auxiliary cam 10, especially as appreciiable in Fig. 5 to Fig. 7 (spring not showing in Fig. 3 and Fig. 4), the second return mechanism can comprise the spring 14 for each auxiliary cam 10, it is by auxiliary cam 10 or be connected to frame 2, be connected to master cam 8, or be connected to the auxiliary cam 10 of separation.In the example of Fig. 5 to Fig. 7, the spring 14 of level 1 auxiliary cam 10 is connected to master cam 8; Similarly, the spring 14 of level 2 auxiliary cams 10 is connected to master cam 8.
It should be noted in the discussion above that by spring 14 and be applied to moment of torsion summation on master cam 8 (for the spring 14 that directly auxiliary cam 10 is connected to master cam 8) lower than being applied to the moment of torsion on master cam 8 by spring 12.
Therefore, according to the example of Fig. 5 to Fig. 7, spring 14 is connected to master cam 8 by level 1 auxiliary cam 10 and level 2 auxiliary cams 10 respectively, each applies moment of torsion (on the first hand of rotation on master cam 8, herein corresponding to left-hand revolution direction), the summation of these moments of torsion is lower than the moment of torsion (on the second hand of rotation, herein corresponding to dextrorotation veer) being applied to by spring 12 on master cam 8.
This allows cam 6 from actuated position to the therefore auto-returned corresponding to the nominal position of stable equilibrium position, and allows to keep master cam 8 in nominal position.
As shown in drawings, each cam 6 can comprise the step that is configured to the building blocks of function 4 that radial support is corresponding in fact in nominal position.Thereby for better robustness, this provides the benefit disappearing of exerting oneself on axis in the situation of collision.
In nominal position, such as step 16 can lock its building blocks of function 4 supporting in case they move, but on actuated position, the building blocks of function 4 that step 16 supports in nominal position with it separates, to allow conversely their movement, the movement that building blocks of function 4 does or mobile shortage make it or can not make it carry out their designed technical functionalitys.
Should also be noted that the contact between each step 16 and the building blocks of function 4 of correspondence can be periodic contact or the contact based on face, and this contact can be moved during cam 6 rotations.
Each auxiliary cam 10 can comprise the circumferential madial wall 18 on the complementary circumferential lateral wall 20 that is designed to be radially superimposed upon low-level auxiliary cam 10 or master cam 8.Therefore, if can be by low-level auxiliary cam 10 or be suitable for, by the lead rotation of each auxiliary cam 10 of master cam 8.
Can, by lead the more accurately rotation of each horizontal N auxiliary cam 10 of horizontal N-1 auxiliary cam 10, can carry out by master cam 8 rotation of guiding horizontal 1 auxiliary cam 10.
Therefore,, according to the example of Fig. 1 to Fig. 7, master cam 8 is as support and the guide of the rotation of level 1 auxiliary cam.For the example of Fig. 3 to Fig. 7, the rotation of guiding horizontal 2 auxiliary cams 10 on level 1 auxiliary cam 10.Similarly, in accompanying drawing 4, support respectively and guiding horizontal 3 auxiliary cams 10 and level 4 auxiliary cams 10 by level 2 auxiliary cams 10 and level 3 auxiliary cams 10.
Madial wall 18 and lateral wall 20 are valuably corresponding to cylindrical sub-fraction.In other words, cam 6 can form the slide pivot connection (cylinder-cylinder) of transition each other.
If only when the low-level auxiliary cam 10 that makes master cam 8 by predetermined rotating part or be suitable for, separate is on the first hand of rotation when pivotable, if by master cam 8 or the low-level auxiliary cam 10 that is suitable for, separates each auxiliary cam 10 is rotated valuably from nominal position.This predetermined rotating part has the angular amplitude that is less than or equal to angle stroke.
It should be noted in the discussion above that in nominal position, each cam 6 has two non-zero relative travel angle α and the β with one or more cams 6 in other cams 6 of this mechanism 1, as shown in Fig. 1 example.Can form by two relative travel angle α and β the angle stroke of each cam 6.
Relative travel angle α and β remain on nonzero value in nominal position valuably, on the one hand owing to supporting corresponding building blocks of function 4 at nominal position overhead cam 6, make the rotation of locking cam 6 on the second hand of rotation, on the other hand due to the return force applying by spring 12 and spring 14.
Described in Fig. 2, once make by predetermined rotating part separate low-level auxiliary cam 10 or master cam 8 along the first hand of rotation pivotable, one of them of relative travel angle, such as angle α, can be zero.
In the time making master cam 8 along the first hand of rotation pivotable by predetermined rotating part, master cam 8 can comprise seating wall 22 valuably, and it is arranged to one of them in abutting connection with auxiliary cam 10 or auxiliary cam 10, for example level 1 auxiliary cam 10.This allows master cam 8 to make to rotate with the auxiliary cam 10 of its adjacency on the first hand of rotation.
The auxiliary cam 10 rotating by master cam 8 can comprise seating wall 22 conversely, in the time making the second auxiliary cam 10 along the first hand of rotation pivotable by predetermined rotating part, this seating wall 22 is arranged in abutting connection with the second auxiliary cam 10, so that the second auxiliary cam 10 rotates along the first hand of rotation.This second auxiliary cam 10 can comprise seating wall 22 certainly conversely, and when the second auxiliary cam 10 is during along the first hand of rotation pivotable, seating wall 22 is arranged in abutting connection with the 3rd auxiliary cam 22, so that the 3rd auxiliary cam 10 rotates along the first hand of rotation, by that analogy.Therefore, generally speaking, each cam 6 can comprise seating wall 22, in the time making cam 6 along the first hand of rotation pivotable by predetermined rotating part, seating wall 22 is arranged in abutting connection with the cam 6 separating, so that the cam 6 seating wall 22 first hand of rotation rotations that separate.
According to the example of Fig. 3 and Fig. 4, therefore drive each horizontal N auxiliary cam 10 by horizontal N-1 auxiliary cam 10, by master cam 8, level 1 auxiliary cam 10 is rotated.
Also possibly, master cam 8 comprises multiple seating walls 22 so that multiple auxiliary cam 10 rotates, or even makes whole auxiliary cam 10 rotate.Therefore,, according to the example of Fig. 5 to 7, level 1 auxiliary cam 10 and level 2 auxiliary cams 10 all directly rotate by master cam 8.
Therefore, master cam 8 is corresponding to the control cam that is designed to directly or indirectly cause that auxiliary cam 10 rotates.
It should be noted in the discussion above that angle [alpha] can be corresponding to the angle between one of them seating wall 22 and the corresponding surface of another cam 6 of cam 6, wherein seating wall 22 is designed in abutting connection with this another cam 6.
If be suitable for, can complete by spring 14 rotation of the cam 6 being driven by master cam 8.In fact, in the time that each spring 14 is connected to auxiliary cam 10 master cam 8 or is connected to auxiliary cam 10, if they can have stiffness constant or the length of the rotation of the auxiliary cam 10 that is applicable to be suitable for master cam 8 on the first hand of rotation or separate, the auxiliary cam 10 that spring 14 connects them rotates on the first hand of rotation.
Therefore, according to the embodiment of Fig. 1 and Fig. 2, spring 14 can have length and make so like this when master cam 8 is during along the first hand of rotation pivotable, and before auxiliary cam 10 moves, angle [alpha] can vanishing.
For control mechanism 1, mechanism 1 can comprise axle 24, and axle 24 is rotatable with respect to frame 2 and extends along the rotation axis of cam 6, guarantees, with respect to axle 24, master cam 8 is installed rotatably, so makes like this rotation of axle 24 cause that master cam 8 rotates.
Master cam 8 can be fixed to axle 24, or connect and be connected to axle 24 by sliding-type.
Especially, master cam 8 can comprise having plane 26, be designed to the centre hole that the shape by mating with axle 24 cooperates.
In addition, one end of axle 24 can extend to mechanism 1 outside valuably to can be captured by user.This end can have grasping member (not shown) to facilitate the crawl to it and conveniently to transmit moment of torsion to master cam 8.
It should be noted in the discussion above that axle 24 can only contact with master cam 8, and can be selectively with respect to master cam 8 free shift.
Should also be noted that angle stroke may reside between axle 24 and master cam 8.
