Turning now to Fig. 1, the manual operation thick stick of the parking brake for actuating motor vehicles is shown schematically herein Lever apparatus 1.Leverage 1 includes lever construction 2 comprising and the base part 3 with front end, arm 4 extend from the front end, And it is terminated with the end lever 5 with any desired state.For example, lever 5 can be indulged as being substantially known in the art It is obtained to the form of the lever of extension or furthermore in the form of lateral handle.

When used in this manual, term " longitudinal direction " and " longitudinally " mean to be mounted in the apparatus according to the invention The longitudinal direction of motor vehicles under conditions of on motor vehicles.Term " transverse direction " and " laterally " mean vertical with motor vehicles The horizontal direction orthogonal to direction.

The base part 3 of lever construction 2 is tiltably mounted in supporting support 6, and supporting support 6 has by any type Interface unit be fixed to any appropriate structuring of motor vehicle construction.In the exemplary case shown, supporting support 6 include from The vertical wall 6a that base wall 6b is upwardly extended, base wall 6b screw are connected to the floor level of motor vehicles.

The base part 3 of lever construction 2 is tiltably mounted on the vertical wall 6a of bracket 6 by means of connection system, It include the first linking arm 7 and the second linking arm 8 in the embodiment that the connection system is shown in figures 1-4.

First linking arm 7 has first end, which is mounted on bracket around the first transverse axis 9 in hinged way On 6 wall 6a.Second linking arm 8 has first end, which is mounted on around the second transverse axis 10 in hinged way On the wall 6a of bracket 6, positioned at the front (direction of advance relative to motor vehicles) of the first transverse axis 9.About preferred solution Certainly in the illustrated example of scheme, the second transverse axis 10 be also located at at 9 substantially the same height of the first transverse axis.Expression " substantially at identical height " be intended to refer to, the theoretical planes comprising axis 9,10 relative to horizontal plane tilt be included in 0 ° and Angle between 45 °.But the characteristic is distinctive to the example of the embodiment shown, and be not excluded for angle wherein and include Possible modification between 45 ° and 90 °.

If the first transverse axis 9 and the second transverse axis 10 are limited in supporting support 6, they are relative to motor-driven The structure of vehicle is in fixed position.The base part 3 of lever construction 2 is lateral rotating around third transverse axis 11 and the 4th Axis 12 is pivotally connected to the second end of the first linking arm 7, and is connected to the second end of the second linking arm 8.

Fig. 1 shows the lever construction 2 in its fully depressed position.In this position, two linking arms 7,8 are orientated Wherein their the second end is arranged at the level lower than the level of first end, and thus, central axes 11,12 are arranged At the low level of the level than axis 9,10.Moreover, two linking arms 7,8 are fixed referring again to the fully depressed position of lever Two intersected to the axis 15 instantaneously rotated for being placed along lever construction 2 for wherein pairs of axis 9,10 and 10,12 In plane 13,14, which is located at 9,10 top of the first and second transverse axis.

With the difference occurred in known solution, as above-mentioned arrangement as a result, the movement of lever construction 2 at it When being moved to complete raised position (being shown in FIG. 3) from fully depressed position (being shown in FIG. 1), the arm 4 of lever and end Lever 5 is shifted according to the path T showed in Fig. 4, which is general olive or general vertical, to increase when lever When, the region at 5 rear of lever is kept sufficiently freely through the moving range of lever 2, and base part 3 and linking arm 7,8 are not The space of " occupying " above them.

The top profile C of the console of the structure of display covering lever 2 is schematically pointed out in Fig. 1, the lever 2 is typically It is designed as being positioned in the space between two front seats of motor vehicles.The shifting of lever 2 is run through in space below the profile Dynamic range keeps the sufficiently free fact that designer is allowed to utilize aforesaid space for designing with possible maximum freedom degree Console, it is contemplated that gloves compartment or bottle retainer etc..

As in institute's reference above, Fig. 1 in attached drawing shows that the lever in fully depressed position, Fig. 3 are shown completely Lever in raised position, and Fig. 2 shows the lever in middle position.

Another preferred characteristics according to the present invention, the lever arm 4 extended from the front end of the base part 3 of lever have curved Bent, gooseneck construction, this is constructed with convexity forward-facing.The construction is substantially known.But to application of the invention Allow to obtain another advantage.The curved configuration of arm 4 can be obtained indeed according to such as bottom profiled, the profile and the movement in lever Period is similar with the profile for the elliptical path that lever 5 follows by arm 4.By this method, the mobile period in lever 2 of arm 4 is by thick stick It is located at the part in position corresponding with the roof C of console in each position that bar 2 uses on the longitudinal direction of motor vehicles Less displacement or not.Thus, the wall C of console can be equipped with slit F in a longitudinal direction with minimum dimension, this permits again Perhaps the more preferable utilization in obtainable space on the roof of console.This aspect becomes bright by the comparison of Fig. 1,2,3 and 4 It is aobvious.

Fig. 4 in attached drawing show the mobile period in lever of overlapping from fully depressed position to complete raised position, One in various positions used by lever.Above-mentioned attached drawing shows and is followed in the movement of lever by the top section of lever Path T, the construction with general olive and general vertical.Fig. 4 also shows the axis 15 by instantaneously rotating, that is, passes through row Intersection into the plane for passing through axis 9,11 and 10,12 is the path followed by the theoretical axis that each position that lever 2 uses limits. As can be seen, the center 15 instantaneously rotated is remained higher than axis 9,10 when lever increases, but moved in lever towards its raised position Decline downwards when dynamic along elliptical path.

Fig. 5 in attached drawing shows the diagram of the connection between lever construction according to the present invention and supporting support 6.The figure Give the various parameters for establishing the geometry of connection system.

Fig. 6 shows the another schematic diagram of the above embodiment of the present invention, is also schematically demonstrated by relevant to lever The basic component of locking device comprising the 20 (list preferably by being fixed on bracket 6 (for example, passing through welding) of sector with teeth Only element composition) and the pawl 21 that operates of conjunction with which.Other structure details of locking device are not shown in attached drawing, have such as mentioned And, it can obtain in any known way.Pawl 21 is connected to release device (not shown) relevant to lever 5 certainly.Together Sample, according to known technique, aforementioned device can be equipped with anti-release safety device.

It is excellent under the proof by selection of the sector with teeth being made of the individual element installed on the frame 6 following situations Point, in this case, for any reason, it may be desirable to modify mechanism some parameters (in general, four length of the bar of mechanism or Only two hinged points of two linking arms in supporting support).It in certain limitations, will be enough only to replace the sub- component, come It is set to follow the correct operation of lever moved and ensure pawl 21.

Certainly, such as those skilled in the art will appear as directly it is readily apparent that not damaging above-mentioned fundamental characteristics In the case where, can refer to lever movement or referring in reduce completely or the position of the lever completely under increasing state and It is required that service load, to select aforementioned parameters (also, length and their orientation of specifically linking arm 7,8), with Just meet any particular requirement.

Under as the specific condition shown in non-limiting example, linking arm 8 has short length more significant than linking arm 7.

As in fig. 1-3 as it can be seen that the second end of linking arm 7,8 is in the connection axis 11 with them, 12 corresponding positions Middle corresponding pin 16a, 17a of carrying, pin 16a, 17a are in guide rail 16,17 (for example, in slit or groove or cam face Form) in be guided, which arranges according to the corresponding circular arc that is substantially centered on axis 9 and 10.

Fig. 7 shows the modification of the solution of Fig. 1-4 and 6, wherein each in no swivel pin in linking arm 7,8 Auxiliary under around axis 9 and 10 be pivotally mounted to supporting support 6, but be only to be shaped like circle in the first end of arm 7,8 Cylindricality hinge components and receive in a rotatable way be formed in bracket 6 in the case where mutually agreeing in seat.For arm 7, the part of 8 hinge end section held seat and form triangle open mouth 16,17, the opening are shaped to allow the swing of arm 7,8, and The end of travel position of respective arms is limited each with two opposite side.As has been said, the solution avoid using Pin gives bigger power, while also limiting any clearance and lateral resistance with for the hinged of axis 9,10 on lever 2 Hinder.

(shown in figs. 8 and 9) according to alternative embodiment, base part 3 only by pin 16a, 17a guide rail 16, Engagement in 17 (see Fig. 7 and Fig. 8) and be mounted in supporting support 6 (that is, linking arm 7,8 is not provided).In the example of figure 7, Two guide rails 16,17 can be constructed according to preferably having with the circular arc of dramatically different radius each other.Alternatively, it guides Track 16,17 is according to non-circular arc (for example, elliptic arc (as in the case of fig. 7)), or again according to include have it is any appropriate The complex outline of the arc of construction and/or straight line portion determines profile.In the case where the solution, in axis 11 and 12 Each movement can thus for the arbitrary and even not approximate rotation being similar to around respective axis 9 or 10.Accordingly, it is contemplated that Only two guide rails, the construction without linking arm authorize complete degree of freedom of the designer in both: construction lever 2 Mobile type；With the position in its end of travel point of construction lever.

Moreover, as can be seen, for example, in fig. 8, which allows the size reduction of bracket 6 to bare minimum, only Want to provide hinge axes 9 and 10 on it for guiding the movement of lever 2.

Obviously, in the case where wherein path 16,17 is not circular embodiment, the third and fourth axis 11,12 is not tight It is moved around first axle 9 and second axis 10 to lattice, so that if these first and second axis limited herein are this The corresponding instantaneous centre of rotation of the axis 11,12 in each position of lever 2 is understood in situation.

As in reference above, expression " guide rail " is used herein to instruction and is suitable for forcing two carried by lever 2 A pin or same element follow any type of guiding piece of corresponding given path.Falling into the term is, for example, directional slit Or groove or there are also any type of cam face.Similarly, joint element 16a, 17a of two guide rails 16,17 can Take the form of pin, otherwise this outer slide or any type of guidance driven member element.

In all embodiments of the invention, in order to which the standardization to component is advantageous, the path and the point for starting and reaching (in height and lengthwise position) can change in limitation, the limitation only pass through change guiding piece or component (for example, arm 7,8 and/ Or path 16,17) characteristic kinematic length are imagined.

Can such as infer from Fig. 5, the distance between ratio and axis 11,12 between the various length of linking arm 7,8, with And be limited to it is corresponding with the fully depressed position of lever under the conditions of arm 7,8 orientation angle only form it is of the invention preferred But non-limiting example, it is therefore clear that aforementioned ratio and angle can be relatively shown herein and change.In any situation Under, Fig. 5 is provided as the example of the value of aforementioned ratio and angle in preferred embodiment.

It is back to Fig. 4, equally schematically illustrates the flexible wire of the parking brake for actuating motor vehicles herein Cable or bar 18 are connected to the base part 3 of (directly or indirectly) lever construction 2 on axis 19.Fig. 4 illustrates how benefit The expectation stroke of cable 18 corresponding with the rotation angle A of linking arm 7, the angle are obtained with the angulation change B of the position of lever 5 Degree changes the approximate half for the rotation that B is arm 7.The connection system of description thus also executes driven multiplication transmission device in following meaning Function: the given angle of the position of lever 5 changes the much bigger angulation change for determining linking arm 7, to ensure to be driven dress Set the desired linear displacement of cable 18.Arrangement as description as a result, also obtaining user must apply to overcome transmission The reduction of the counteractive workload of device, the reduction are especially strengthened in the raised final step of lever.Thus, it removes It presents with except the related above-mentioned advantage of the bigger freedom degree utilized in space of lever, the present invention also presents more easypro Suitable and advantage easy to use.

As clearly shown from the foregoing description, the present invention authorizes designer in the movement for limiting lever and in its movement The complete degree of freedom on its position in two endpoints.The advantage is especially apparent in following solution, which sets Think that the base part of lever only passes through installation of two guide rails in supporting support, but they are formable, before passing through State the guidance driven member element engagements such as two pins or the sliding block of base part carrying.In this case, the present invention is using upper The term of position limits, as follows:
