A vehicle end accessory (2,2') is provided with a lever mechanism with multiple levers. The lever mechanism is assembled from two rotating levers (5,5',6,6') connected in a connection point (4,4',7,8,8') designed as a hinge. The rotating levers are folded together in a folded form of vehicle top, and are unfolded in an opened condition of another vehicle top.

Description

The invention relates to a motor vehicle cover with a lever mechanism and a force-generating tool with the features mentioned in the preamble of claim 1 and claim 13.

It is known that tailgates and hoods and doors of vehicles are hinged to a vehicle body by means of hinges and hinges and can be equipped with power-generating tools for their manual, semi-manual or automatic opening and closing, for example with springs, gas springs or electromechanical / pneumatic / hydraulic drives , Under certain circumstances, take the joints, hinges and the force-generating aids so much space for themselves that they can be a significant impediment to loading and unloading of the vehicle or contribute to reducing the useful space of a trunk or engine compartment. Further, it is important that opening and closing can be done reliably and comfortably to the user even under various circumstances, such as a car leaning obliquely, both in a vertical trunk lid of a combination vehicle and in a horizontal trunk lid of a saloon.

DE 10 2006 019 478 A1 describes a tailgate mechanism of a vehicle, with a compact design of the tailgate mechanism is implemented by the fact that a force-generating gas spring acts on a force-translating lever with a short lever arm length and the same lever acts with its other longer lever arm on the lid to be moved. Both lever arms of the force-translating lever are positioned relative to a common axis of rotation of the force-translating lever to each other at an angle selected such that the rotatably mounted gas spring when opening and closing the tailgate has to perform only a relatively small pivoting movement, whereby the gas spring takes up less space for itself , In addition, the gas spring is rotatably mounted on an inner surface along the tailgate and thereby can be installed concealed due to their relatively low deflection movement under the cowl of the tailgate. The long lever arm of the power-translating lever acts with its remote end directly on an inner surface of the tailgate, whereby this end can not be connected by a hinge, hinge or the like with the tailgate, but must slide on a dedicated inner surface of the tailgate. As a result, upon reaching about half the opening angle of the tailgate, the pressurizing effect of the long lever arm is interrupted and on further opening, the gas spring alone acts with its pressure force on the tailgate directly.

The gas spring may be replaced by a motor drive and also be mounted on the vehicle body instead of in the tailgate. The transition of the force acting on the tailgate of the effect with the long lever arm to force without the long lever arm should be felt by the user and affect his sense of comfort. In addition, the sliding, connectionless power transmission structure thereby causes a significant drawback that, if instead of the gas spring, a motor drive is to be used, this can not bring the tailgate back, since the long arm lever would easily solve in this case from its contact point and the entire force transmitting lever would be pivoted about its axis of rotation in the inward direction. To remedy this would make it necessary to provide the sliding of the long lever arm with the tailgate with the end of the long lever arm additional retaining conventional sliding device, such as a plate with a longitudinal opening in which, for example, arranged at the end of the long lever arm transverse pin slidably in Intervention is. Overall, then would result in a rather complex arrangement that would require a correspondingly high installation costs.

EP 0 219 391 B1 (equal to US 4,679,841 ) discloses another compact mechanism for assisting the opening and closing operation of a lid such as a tailgate of a vehicle. Here, the tailgate lid is supported with the multi-link mechanism according to the invention only in the first phase of an opening operation of the tailgate, because in this phase at a small opening angle of the available lever is very short. The multi-link mechanism has four lever arms rotatably connected to each other via four pivotal axle bearings, the main lever having at its end a sliding bearing in the form of a wheel which rolls on a rolling surface of the vehicle body during opening of the tailgate lid and the substantial force between the tailgate lid and the vehicle body transmits, similar to the previously described publication DE 10 2006 019 478 A1 ,

If the opening of the tailgate lid with the multi-joint mechanism has reached a certain opening angle, the power cylinder of a gas spring or a motor drive is in a more favorable angular position relative to the axis of rotation of the tailgate lid, in which its active lever is already sufficiently enlarged, so that for the further opening movement of the tailgate lid the force exerted by the power cylinder sufficient force to move the tailgate cover until it stops in its full open position. In this case, the multi-joint mechanism is moved and lifted the sliding bearing of the rolling surface of the vehicle. In this phase, the multi-link mechanism is already ineffective and the power cylinder acts alone and directly in a conventional manner on the tailgate lid to be opened. The proposed multi-link mechanism is housed in the space between Weckklappendackel and vehicle body, which is formed between a sealing curb of a trunk and the outer body surface for drainage of rainwater. This means that the multi-link mechanism and the power cylinder are fully visible when the tailgate lid is open and therefore carry the risk of pinching the user's or another person's fingers. The power cylinder is in this case mounted on the side facing away from the axis of rotation of the tailgate cover side, so that it crosses the opening angle range between the tailgate lid and the vehicle body with the lid open, which he may be in the way when the user wants to insert bulky items in the vehicle or remove ,

The invention has for its object, in view of the above-mentioned disadvantages and deficiencies due to space unfavorable power unfoldings of a flap opening system with a force-generating tool to improve with a proposed flap opening system that it takes up less space, a more favorable arrangement of the individual elements of the system is possible, the parts of the system do not hinder access to the part space of the vehicle to be closed with a closure lid, the hands and fingers of the user are not in danger of being pinched by parts of the system, and that the system and its components are inexpensive to manufacture and install. Furthermore, it is an object of the present invention to reduce the weight of the individual parts and the overall system, concealed install the parts of the system as possible concealed parts and dustproof for the system parts provided openings in the trim parts, and under realities of a vehicle body that System easier to integrate.

Characterized in that in a motor vehicle lid with a hinge mechanism defining its axis of rotation for attaching to a vehicle body, at least one force-generating tool, which is connected to a force-generating means associated with this power tool, consisting of several levers lever mechanism, and with a locking mechanism, the lever mechanism of two one of the two levers is rotatably mounted on the side of the vehicle body with its other vehicle body side end pivotally mounted in a vehicle body side joint and the second lever with its other end on the side of the motor vehicle lid is mounted in a cover lid side arranged joint and the force-generating tool acts on one of the two levers at a point that does not interfere with the vehicle-mounted joint or the Schließdec arranged on the hinge side of the two rotatably connected lever, but in a predetermined effective lever arm corresponding distance thereof is arranged on the respective lever, and the rotatably interconnected lever in the closed state of the motor vehicle lid are essentially folded and opened when the motor vehicle lid is open substantially , The object of the invention with the features of the main claim 1 is achieved.

According to a preferred embodiment of the present invention, the other end of the force-generating aid is rotatably mounted in a fixedly anchored bearing joint.

According to a further embodiment of the present invention, the vehicle body-side lever, its bearing point on the vehicle body side arranged joint, the direction of action of the force-generating tool and the point of application of the force-generating tool are arranged so that an arm lever of predetermined length comes about and the closing cover side lever, its bearing point arranged on the closure cover side joint, the direction of action of the force-generating tool and the point of application of the force-generating tool are arranged so that an arm lever of predetermined length comes about when the motor vehicle cover is in the closed state. By prescribing dimensioning of these two arm lever lengths, the initial opening force and the torque generated by them can be configured so that a desired supporting or all-inclusive auxiliary effect is achieved when opening the motor vehicle cover.

According to a further aspect of the present invention, the jointed connection point of the two levers is also a rotatable connection and engagement point of the force-generating means. By collapsing the connection point of the two levers with the point of application of the force-generating aid, a joint can be eliminated, which contributes to reducing costs.

According to yet a further embodiment of the present invention, the degree of freedom of the rotational movement of at least one joint of the overall structure is limited to only one plane of rotation, so that thereby the rotational movements of the remaining joints are limited to this plane of rotation, because the rotational movement of the motor vehicle cover by its hinge bearing already on a level is restricted.

With a further inventive embodiment of the present invention, the plane of movement of the joints of the overall structure relative to the plane of rotation of Kraftfhrzeugdeckels inclined to an arbitrarily oriented, predetermined angle, which is selectable between a value of 0 ° and <90 °. By means of these features according to the invention, it is possible, on the one hand, to be able to freely choose the attachment points of the joints with a greater degree of freedom on the vehicle body and the motor vehicle lid and, on the other hand, it is possible to use only one hinge joint with a fixedly oriented axle, while all other joints involved can also be designed as ball joints. This corresponds to the real conditions on a vehicle, which usually has obliquely extending, complex shaped side surfaces, so that a strictly parallel to the hinge of the motor vehicle lid arrangement of all joints of the lever mechanism according to the invention is not possible in the rule.

According to yet another embodiment of the present invention, the rotatable mounting of the force-generating auxiliary means, for example a gas spring, is arranged with its joint on the vehicle body. This attachment point is preferred in tailgates with vertical arrangement as in combination and minivan vehicles and is particularly advantageous when the gas spring is mounted outside the vehicle interior in the rainwater gutter between a sealing edge region of the boot opening and the adjacent outer body surface.

According to yet another embodiment of the present invention, the rotatable mounting of the force-generating means, such as a gas spring, with their Joint arranged on the motor vehicle cover. With this arrangement it is achieved that the force-generating tool can be hidden under the panel of the motor vehicle cover.

In yet another embodiment of the present invention, the force-generating tool is a pressure force generating device. This device may be a compression spring, gas spring, coil spring or a motor drive with a controller.

Also in another embodiment of the present invention, the force-generating means is a zugkrafterzeugende device, such as a draft gas spring, Zugspiralfeder or an electromechanical motor drive with a controller.

In a particularly preferred embodiment of the present invention acts in a motor vehicle lid, with a hinge mechanism defining its axis of rotation for attaching to a vehicle body, at least one force-generating tool, which is equipped with a lever mechanism consisting of a plurality of levers associated with this force generating tool, and with a locking mechanism, the force-generating tool via a pull cable to a point of application of the lever mechanism.

And in yet another embodiment of the invention, the traction cable is arranged over at least one arranged between the force-generating tool and the point deflecting and guiding means arbitrarily aligned in the vehicle body and laid clamped. According to the invention the deflection and guide means is designed as one or more rotatably mounted rollers and / or sliding guides, which make it possible to move the pull rope in any direction.

This makes it possible in an advantageous manner, for example, in a further inventive embodiment of the present invention, the force-generating aids in any subspace of the vehicle body not pivotally and firmly anchored to arrange, for example, under the panel in a side region of the body, in the roof area, in Closing lid and the like, and thereby to choose any orientation., In addition, the force-generating tool is not pivoted when opening and closing, thereby saving space and some costly parts such as the rotatable mounting of the force-generating tool completely eliminated. Furthermore, the pull rope according to the invention has any known cross section in order to be able to realize high tensile loads at the same time with a high degree of flexibility.

This preferred embodiment of the present invention with a cable drive of the motor vehicle cover is also combinable with the aforementioned features and various preferred embodiments of the present invention, so that the motor vehicle cover rotatably mounted on the vehicle body with a defined in one of the previously described embodiments of the present invention , Two lever lever mechanism is provided.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.

FIG. 1 shows an exemplary schematic overall arrangement 13 of a motor vehicle cover 1 with lever mechanism according to the invention 5, 6. The motor vehicle lid 1, 1 'is pivotally mounted on a vehicle body by means of its axis of rotation defining, symbolically shown hinge 9 and can between a closed position 1 and an open position 1 'to be pivoted.

The lever mechanism according to the invention consists essentially of two levers 5 and 6, which are rotatably connected to each other by a hinge 4, 4 'and each with its other ends vehicle body side in a hinge 7 and the closing cover side and in a hinge 8, 8' are rotatably mounted. The position of the joint 8, 8 'on the inside of the motor vehicle cover 1, 1' is spaced from the hinge 9 of the motor vehicle cover at a predetermined distance, to form a sufficient lever length for generating a required opening torque. In the present example, the position of the joint 7 of the vehicle body-side lever 5 is chosen symmetrically opposite the joint 8, but in a further embodiment can be chosen relatively freely in a relatively large area deeper in the vehicle body. The here only by way of example the same length and symmetrically arranged lever 5 and 6 are almost collapsed at a closed vehicle lid 1 at a relatively acute angle and are when opening the motor vehicle lid to position 1 'unfolded. In the present example of an advantageous embodiment, the end of the rod 10 of the force-generating aid 2 is pivoted at the connection point in the joint 4 of the two levers 5, 6, whereby the joint 4 rotatably supports a total of three connected by it lever. Therefore, it is advantageous to carry out this joint 4 by means of an axle on which the three said levers are each plugged and held together with an annular bearing seat, the force-exerting rod 3 advantageously taking the central position under the three annular bearing seats for reasons of symmetrical application of force , The storage with ball joints would not be so easy in this case, as this would several attack points are formed side by side.

The force-generating tool 2, for example, a gas spring, is also rotatably mounted with its other end in a hinge 10 to give the force-generating tool 2 a necessary freedom of movement when opening the motor vehicle cover 1, 1 '.

The positions of the bearing of the joints involved 4, 7, 8 and 10 are chosen so that when the motor vehicle cover 1 is closed by the arrangement arm lever lengths a and b sufficient to generate with the existing force from the force-generating tool 2, a torque to the Opening or to support a manual opening of the motor vehicle cover 1, 1 'may be considered sufficient. The arm lever lengths a and b must not both be chosen to be too small or zero, since otherwise almost no initial torque could be generated in this case. However, given the presence of two rotatable levers 5, 6, two are also in the same direction acting torques are generated. Once it is the torque corresponding to the arm lever length b to the pivot point of the permanently attached to the vehicle body 12 joint 7 and this is added to the torque corresponding to the arm lever length a, which acts around the joint 4. This makes it possible, for example, by increasing only one of the arm lever lengths a or b to increase the total torque, which can be done particularly advantageous by increasing the arm lever length b, since the arrangement of the fixed to the vehicle body 12 mounted joint 7 relatively free a deeper in the vehicle location can take place.

When the motor vehicle cover 1 is released from its engaging engagement in a closing device (not shown), the force-generating aid 2, for example a gas spring, pushes the rod 3 with the force prescribed by the tensioning on the joint 4, which torque is the two torques described above generated, which adds together at the joint 8, a force whose decomposition in a force parallelogram on the turning of the motor vehicle cover 1 directed force F shows. Upon further opening of the motor vehicle cover 1, the arm lever lengths a, b are increasingly larger and the total torque generated increases until the motor vehicle cover 1 has been brought by an angle β to stop in its open position 1 '.

Here, in the simplest case, the plane of rotation of the motor vehicle cover 1, 1 'and the plane of rotation of all participating joints 4, 7, 8, 10, which would require, however, that all involved in the lever mechanism part are strictly aligned parallel to each other. However, such a limited orientation is difficult or impossible on a real vehicle, since the vehicles usually have very curved body surfaces and areas, especially in the area of a motor vehicle cover 1. However, the present invention provides, with a simple additional means, an elegant solution to this problem, which is to impose on one of the hinges 4, 7, 8, 10 limited rotational movement limited to one plane of rotation, while all other joints receive two rotational degrees of freedom means, at least one of the joints 4, 7, 8, 10 is designed as a Einachsengelenk and all other joints 4, 7, 8, 10, for example, as ball joints. Then, the plane of rotation of the joints 4, 7, 8, 10 with respect to the plane of rotation of the motor vehicle cover 1, 1 'have a nearly arbitrarily oriented and relatively large angle, which should logically, however, be between 0 ° and about 30 °.

Since, as stated above, the hinge 4 is advantageous to perform as a one-axis joint, since it connects three levers 3, 5, 6 in this embodiment of the invention, just this joint can be 4 preferably as the one-axis joint and all other joints 7, 8, 10 be designed as ball joints. This gives a designer greater degrees of freedom available to easily integrate the lever mechanism according to the invention under real conditions of a vehicle body.

In FIG. 2 is a schematic overall arrangement 13 of a further embodiment of the motor vehicle cover 1 with the lever mechanism according to the invention to see.

This is different from the execution in FIG. 1 only the point of application 11 of the force-generating device 2 from the connection point 4 of the lever 5, 6 arranged offset to one example on the lever 5 of the connection point 4. With this feature, the design has further freedom to adapt the lever mechanism according to the invention to the conditions of a real vehicle arrangement and to achieve a desired leverage at different opening angles β. The point of application 11 can also be positioned in the same way in a further embodiment of the invention on the other lever 6. It can be clearly seen that the length of the two arm lever lengths a and b can be influenced by the choice of the point 11, which gives the designer an additional design means.

This exemplary arrangement works the same way as the under FIG. 1 described embodiment of the invention, which is why has been omitted here a repetitive description of the same functionality. It should be noted, however, that in this arrangement, all the joints involved 4, 7, 8, 10 and 11 are equal, since they connect only two rotatable each lever, therefore, each of these joints 4, 7, 8, 10, 11 equally selected be designed to be a one-axis joint to define a plane of rotation of all joints involved, while the remaining joints are executable as ball joints.

FIG. 3 shows a schematic overall arrangement 13 of yet another embodiment of the motor vehicle cover 1 with lever mechanism according to the invention, wherein the force-generating tool 2 on the motor vehicle cover 1, preferably at the lower, inward pointing into the vehicle side is arranged.

For this purpose, the bearing joint 10 of the force-generating means 2 is positioned on the inside of the motor vehicle cover 1 and can thereby advantageously under the panel of the Motor vehicle lid 1 be installed concealed, especially if you select the length of the lever 5 and 6 optimized for this purpose.

In this embodiment, the levers 5 and 6 are selected to be different lengths, whereby the vehicle-side hinge 7 can be positioned lower on the vehicle body 12. It can also be seen that the longer the vehicle-side lever 5 is selected, the shorter the second lever 6 may be, thereby allowing the designer to make the deflection angle α of the force-generating tool 2 smaller in order to release the force-generating aid 2 under the Covering the motor vehicle cover 1 installed concealed and only a small section for the freedom of movement of the lever 5, 5 '; 6, 6 'or possibly even 3, 3' to provide.

The concealed arrangement of the force-generating device 2 under the panel (not shown) of the motor vehicle cover 1 is advantageous because no visible parts are arranged laterally of the motor vehicle cover 1 and the space under the panel of a motor vehicle cover 1 then usually has enough unused space reserves.

FIG. 4 shows a schematic overall arrangement 13 of a further preferred embodiment of a motor vehicle cover 1, 1 'with inventive lever mechanism, which is designed for actuation by a tensile force.

In order to use a force-generating means 2, 2 'designed to generate a tensile force, the lever mechanism according to the invention, consisting of two levers 5, 6, is in comparison with the previously described embodiments on the bearing points 7, 8 otherwise arranged in the same way Folded opposite direction arranged so that the attack and connection point 4 of the two levers 5, 6 has been displaced significantly closer to the hinge 9 of the motor vehicle cover 1.

In the closed state of the motor vehicle cover 1 ', the levers 5, 6 are almost collapsed, as in the previously described embodiments, but in the other direction. A for this reason in comparison with previous versions longer tie rod 3 is rotatably connected to the hinge 4 and, for example, acted upon by a tensile force on the spring or gas spring with a tensile force.

After unlocking the motor vehicle cover 1 acts in the same manner as described above, but with a different sign, a force generated by the force-generating means 2 as a tensile force on the point 4 of the lever mechanism according to the invention and acts in the same way with the predetermined arm lever lengths a and a b force-supporting on the motor vehicle cover 1, whereby it is acted upon by a predetermined torque about the hinge axis 9 in the opening direction.

Upon further opening of the motor vehicle cover 1, the levers 5, 6 of the mechanism according to the invention are opened and take in the open position of the motor vehicle cover 1 'their by reference 5' and 6 'marked position.

The force-generating tool 2 pivots in this case as usual by an angle α, for which it is rotatably supported in a bearing joint 10 in the same way.

This arrangement offers the advantage of being able to use a force-generating aid 2, 2 'designed for the generation of a tensile force and thus opens up further design freedom for the designer. In particular, the tension rod 3 can be designed as a cable, whereby weight can be saved and a fixed arrangement of the force-generating aid can be applied without swivel angle. In a further embodiment of the invention, the force-generating tool 2 may be similar to the one below FIG. 3 described be displaced for mounting on the motor vehicle cover 1.

For setting a defined plane of movement of the levers 5, 6, 3 applies as before, that at least one of the involved joints 4, 7, 8, 10 is to be executed as a one-axis joint, while the remaining joints may have two degrees of freedom as ball joints.

FIG. 5 shows a schematic overall arrangement 13 of a motor vehicle cover 1 with inventive lever mechanism, which is designed for actuation by a pull cable 14.

This preferred development of the lever mechanism according to the invention significantly improves the drive part of the lever mechanism, wherein the arrangement substantially of the arrangement of the embodiment of the invention FIG. 1 corresponds, which is why a repeated description of the same parts as the lever 5, 6 and their joint bearings 7, 8 and 4 is omitted.

According to the invention, for example, a further bearing is arranged as a deflecting and guiding means between the hinge 9 of the motor vehicle cover 1 and the joint 7 on the vehicle body 12 and in this case as an example designed as a deflecting roller 15. Around this guide roller 15 around a pull rope 14 is clamped, which is fastened with its visible end to the connection point 4.

In this way, the traction cable 14 can be laid deeper in the vehicle body 12 so as to be tensioned around further deflecting and guiding means in any desired direction, as a result of which virtually any desired location for accommodating the force-generating aid (not shown) can be selected, for example under the cladding in FIG Headliner or in the side posts of the bodywork.

Laying in a further embodiment of the invention, the storage of the deflection and guide means 14 on the underside of the motor vehicle cover 1, the force-generating tool can also be easily housed under the panel of the motor vehicle cover 1. In both cases, no cutout for the swiveling levers 5, 6, 3 must be carried out in the cowl of the motor vehicle, through which, for example, dust can get inside the cladding and thus become a problem. The traction cable 14, however, can be designed by a fixed dust seal in the form of a conventional rubber sleeve surrounding the pull cable 14.

Furthermore, the use of a pull rope 14 instead of a solid rod 3 brings considerable weight advantages, since all materials are much more effective on train loadable and therefore may be dimensioned much smaller in cross-section than a pressure load. In order to implement a high tensile load with good flexibility of the hauling rope, the hauling rope can be designed as a flat belt of smaller thickness and greater width.

In addition, the force-generating tool may now have any outer shape, for example circular or rectangular, and need not be designed solely as a long drawn object to be accommodated in the vehicle water drain groove adjacent to the motor vehicle cover 1. On the contrary, according to the invention, the force-generating means can thereby be completely removed from the field of vision and access of the user, as shown in the present embodiment. The designer thus has more design freedom available and it can be used any known force-generating tools.

It should also be noted in particular that many of the conventional lever mechanisms described above have been advantageously driven by the use of a traction cable drive 14 according to the invention.

The foregoing embodiments of the present invention are to be considered as illustrative and not restrictive of the present invention. The present invention can easily be applied to other applications. The descriptions of the embodiments are provided for illustration and not to limit the scope of the claims. Many alternatives, modifications and variations will be apparent to one of ordinary skill in the art without departing from the scope of the present invention as defined in the following claims.
