Description

stop element

The present invention relates to a stop element, in particular a dummy buffer, for adjusting body parts, such as front or tailgates, z. As passenger cars, a mounting kit, a method for positioning of body components and a use of a stop element.

Body parts, such as hoods and tailgates, are usually articulated via hinges connected to the respective vehicle body. In a stop position, the body component is still engaged or locked in a locking device and is also located at z. B. two stop buffers, so that the body component forms a substantially closed unit together with adjoining body exterior parts. Such bumpers are usually adjustable in height or length. In a correctly adjusted state, the respective body component bears against the locking device, for example the tailgate lock, and the hinges as an abutment with a predetermined pretension. During production of the motor vehicle, this stop position of the body component, including a predetermined preload, for example with the aid of "dummy buffers", is adjusted with considerable manual effort, this serving in particular to determine a desired distance between the respective body component and the body structure The problem with this is that, depending on the closing speed or the closing force, the dummy buffer is pressed in different degrees, whereby possibly no correct distance or preload value can be determined Dummy buffer, but with the disadvantage that the component to be adjusted must be opened and closed several times in order to tamper with the correct bias voltage Such a procedure is therefore extremely tedious. It is therefore an object of the present invention to provide a stop element, a mounting set, a method for positioning of body components and a use of a stop element, which allow a quick and efficient setting of body parts, in particular to each other.

This object is achieved by a stop element according to claim 1, by a mounting set according to claim 8, by a method according to claim 9 and by a use according to claim 1 1. Further advantages and features will become apparent from the dependent claims and the description and the accompanying figures.

According to the invention comprises a stop element, in particular a dummy buffer, for adjusting body parts or body flaps, such as rear or front flaps of z. B. passenger cars, an arrangement area and a stop area, which are resiliently mounted to each other, wherein the arrangement area is designed for the arrangement of the stop element on a first component and wherein the stop area is designed as a stop for a second component, and wherein the stop element comprises a locking mechanism, which is designed to lock or lock a position or position of the stop area relative to the arrangement area. The first component may be the movable body component, such as the tailgate. The second component is possibly a vehicle or body frame or a vehicle or body structure. Alternatively, the embodiment is also reversed. For example only, the first component is referred to below as the tailgate and the second component as a body structure. The tailgate expediently comprises a corresponding arrangement section for arranging the arrangement region of the stop element. Conveniently, this is or here a positive and / or non-positive connection or attachment provided. For example, a kind of bayonet closure is advantageous, since this both allows quick attachment and a quick release of the stop element. In a preferred embodiment, the stop region comprises a stop surface, which is, for example, spherical or in the form of a circle segment or a half shell. The stop region and / or the abutment surface are expediently formed of a material which enables a secure application / abutment on the body structure, in which case the material is selected in particular in such a way that no scratching, or more generally, damage to the body structure can take place. Conveniently, the abutment region and / or the abutment surface is or are formed from a corresponding rubber material or coated with such a material. Alternatively, however, the stop area and / or the stop area may also be made of metal, in particular if, for example, the body structure is provided with a corresponding material at the corresponding location. In principle, the stop element can be made, for example, of metal or of plastic or of a combination of the aforementioned materials. The great advantage consists in the fact that the stop area or its stop surface are mounted resiliently with respect to the arrangement area, whereby overshooting of the tailgate during closing can be compensated. By the suspension is thus always ensured that the stop area in the respective end position or closing position of the tailgate rests against the body structure. The safe concern is ensured regardless of the closing force and the closing speed. When closing the tailgate, it may, depending on the closing force and / or closing speed, come to an "overshoot", ie the tailgate is briefly moved closer towards the body structure than is provided in the actual end, closing or stop position The spring element is now designed to absorb or cushion this "overshoot". Without this spring mechanism, the stop area would, so to speak, remain in a "too deep" position If, after closing the tailgate, it opens again to a distance between the two To measure arrangement area and the stop area or the stop surface, then this value would be too small. By this resilient mounting this disadvantage is effectively avoided. As a second important advantage is added that the locking mechanism is provided, which is designed to lock the position or position of the stopper area relative to the arrangement region. In other words, therefore, the aforementioned state of the stop area or its position in the closing, Endbzw. Stop position or position of the tailgate "frozen" or fixed.

According to one embodiment, the stop element comprises a base body which extends along a longitudinal direction, wherein the stop area is movably mounted along the longitudinal direction. In the assembled or installed state of the stop element, the longitudinal direction expediently extends along a closing tangent of the tailgate in the region of the stop element.

According to a preferred embodiment, the stop element comprises a spring mechanism, via which the stop area, in particular resilient, is mounted. According to one embodiment, the spring mechanism comprises a spring element, for example in the form of a helical spring. Alternatively or additionally, a rubber or elastomeric element may also be used. According to various embodiments, hydraulic systems and / or pneumatic systems may additionally or alternatively be used in order to provide the spring effect or else a damping effect. According to preferred embodiments, the provided travel is about 3-10 mm, preferably about 4-8 mm. Typical spring stiffness, especially when using a coil spring, are z. In a range of about 1 to 3 N / mm, for example about 2 N / mm. Preferably, the locking mechanism is operated remotely. This is particularly advantageous because in many vehicle types or variants, such as sedans, the one or more stop elements in the closed, end or stop position of the tailgate are not accessible. This is certainly possible with some combi vehicles. As a rule, however, there is the problem of accessibility, so that in the present case it is particularly advantageous that the locking mechanism can be operated "remotely", for example from outside the vehicle or the body structure, so that a fitter can comfortably stand next to the vehicle or the body structure and then fix, lock, lock, etc., via the locking mechanism, the position of the abutment portion relative to the disposition portion. Conveniently, the abutment member comprises actuating means adapted to actuate the locking mechanism, especially remotely.

According to one embodiment, the locking mechanism z. B. mechanically formed, wherein the one or more actuating means are designed as a Bowden cable. The mechanically formed locking mechanism is according to one embodiment, for example, on the principle of self-locking. By means of the Bowden cable, a correspondingly formed socket can be tightened / displaced in the interior of the stop element and locked by the provision of corresponding wedge surfaces or wedge elements. The design is not critical and interpreted by the skilled person depending on the case. According to one embodiment, the stop element, for example, a corresponding, in particular external, sleeve, which can be loosened by turning the fixed inside the stopper member by self-locking sleeve again.

According to an alternative embodiment, the locking mechanism is electrically and / or magnetically formed. For example, a coil or a magnet can be provided in the stop element, which can be actuated by energizing, so that a position or position of the attachment can be actuated. Schlagbereichs is fixable. A release is then very easily possible, for example, that the current flow is interrupted again or vice versa.

Depending on the configuration of the locking mechanism, the actuating device or the actuating means may also be designed "virtually / contactlessly", for example when the operation is wireless or can take place, for example by transmitting a radio signal.

The invention is also directed to a mounting set, comprising at least two stop elements, in particular comprising two stop elements according to the invention, and an actuating device, wherein the at least two stop elements each have a locking mechanism and actuating means and wherein the actuating device is designed, the actuating means, in particular even at the same time actuate.

A tailgate is fixed or adjusted for example via two stop elements in a closed, end or stop position. By simply actuating the actuating device, both stop elements or their locking mechanisms can then be actuated, for example "at the push of a button." Very rapid adjustment of the tailgate is therefore possible, in particular primarily because the stop elements need not be fixed individually or one after the other As far as the actuating device is concerned, what is mentioned in connection with the actuating means or the locking mechanism is essentially the same, in which case the actuating device can also be a mechanical system Alternatively, an electrical and / or magnetic design can also be used , in particular with the aid of, for example, wireless data transmission, for example by means of radio signals, be possible. The invention is further directed to a method for positioning or adjusting body components to one another, comprising the steps:

- Providing at least one stop element, in particular a stop element according to the invention, which has an arrangement area and a stop area, which are resiliently mounted to each other;

Arranging the at least one stop element in or on a first component;

- Positioning of the first component and / or a second component relative to each other, wherein in this case a position or position of the abutment portion is changed relative to the arrangement region;

- Fernarretieren or remote locking the position or position of the stop area.

By positioning is meant in particular a closing of the corresponding movably mounted body component (first or second component). In a closed, end or stop position, the body component, such as the tailgate, in a locking device, such as a tailgate lock, engaged. Due to the resilient mounting of the stop area of the stop element is independent of the closing force and the closing speed reliably on each opposite component. The remote locking now advantageously allows the "freezing" of this state.

For the method and for the aforementioned mounting set the advantages and features mentioned in connection with the stop element apply analogously and accordingly and vice versa.

Conveniently, the method may additionally comprise one or more of the following method steps, these again referring to the example "tailgate":

- opening the tailgate;

- Removal of the stop element; Measuring the stop element, in particular measuring a distance, or transmitting a distance of the stop area relative to the arrangement area onto a stop buffer; the bump stop is the element that should be installed in the finished vehicle; in the case of the aforementioned transfer, an additional dimension is expediently automatically taken into account for the stop buffer, as a result of which a desired pretension can be set; It should be noted at this point that the stop element is significantly more complex in design than the stop buffer, so that the stop element, which is also referred to as a dummy buffer, is to be understood as a tool to set the "final" stop buffer correctly;

- Install the stop buffer (s) in places where the stopper / dummy bumpers were previously installed.

According to one embodiment of the method, the aforementioned positioning of the first and / or the second component comprises, in particular elastic, deformation of the respective component. A large, flat component, such as a tailgate, due to its size, for example, based on its width, always has a certain dimensional deviation. Simply put, for example, the tailgate is slightly warped or crooked, with this delay z. B. may be caused by the painting process. This can now in the closed, end or stop position of the tailgate z. B. lead to the problem that the tailgate on one side, for example, right, is slightly too high, while on the other side, for example, left, is slightly too low. Advantageously, this offset can be compensated for by pressing something on the tailgate, for example, on the right, until it reaches a desired position / position. In this state, the locking mechanisms of the stop elements is or will now be actuated. About the aforementioned actuator, the locking mechanisms can be activated with advantage even possibly simultaneously. In the present example this means that by pressing on the tailgate, the stop area in the right tailgate area is still slightly displaced in the direction of the arrangement area, while the stop area in the left area of the tailgate further increases its distance relative to the arrangement area.

Due to the resilient mounting but both stop areas are still in contact with the body structure. The tailgate is now in its desired position and this condition can be adjusted by the operation of the locking mechanisms. The tailgate is thus aligned on the stop elements so ideally, biased and in particular so that differences in height to adjacent components, gaps, etc. are set ideal or desired. The entire method is particularly simple in that the locking mechanisms can be operated remotely.

Finally, the invention also relates to a use of a stop element according to the invention for the assembly of vehicle bodies or for the adjustment of body components, in particular to each other. In particular and preferred here is the setting of front flaps, such as hoods, or tailgates, such as trunk lids, doors, moving flaps, such. B. tank flaps, or other attachments meant. With regard to use, the advantages mentioned in connection with the stop element, the assembly set and the method apply analogously and correspondingly, and vice versa.

Further advantages and features will become apparent from the following description of an embodiment of a stop element with reference to the accompanying figures.

Show it:

Fig. 1: an embodiment of a stop element; Fig. 2: a sketched arrangement of the known from Fig. 1 stop element.

Fig. 1 shows a stop element 20 comprising a base body 26 which extends along a longitudinal direction L. The stop element 20 has a substantially planar arrangement region 22, from which several, for example two, pins 36 extend away (only one of which can be seen in the view represented here). These pins 36 serve to fasten or position the arrangement region 22 on a body structure or vehicle flap, not shown here, and in particular prevent twisting of the stop element 20 about the longitudinal direction L. Relative to the arrangement region 22, a stop region 24 is arranged at a distance a1. In the embodiment shown here, the suspension is realized via a spring element 30. The stop element 20 is shown partially cut, whereby it can be seen that it is the spring element 30 is an internal coil spring. Alternatively, the spring element 30, for example the helical spring, could also be arranged on the outside. With the double arrow, denoted by the reference numeral x, the mobility of the stopper area 24 along the longitudinal direction L is outlined. In the interior of the stop element 20, a locking mechanism 40 is formed, which serves to lock or lock the stopper portion 24 in a desired or predetermined position / position. The locking mechanism 40 is actuated in the embodiment shown here via an actuating means 42 in the form of a Bowden cable, in particular from a distance. For this purpose, the Bowden cable has a corresponding length, which is dimensioned, for example, such that the locking mechanism 40 can be operated from outside the body structure (not shown here). The locking mechanism is mechanically formed in the embodiment shown here and is based on the principle of self-locking. In order to release the locking mechanism 40 again or unlock, is a rotatable sleeve 44th intended. On the exact configuration of this mechanical solution will not be discussed here.

FIG. 2 now shows the stop element 20, which is essentially known from FIG. 1, comprising a main body 26 which extends along a longitudinal direction L. The stop element 20 is arranged via an arrangement region 22 in or on a first component 11, wherein the first component 11 could, for example, be a tailgate of a vehicle. The stop element 20 comprises a stop region 24, which serves as a stop against a second component 12, which may be, for example, a vehicle frame or a body structure. A reference numeral a2 denotes a space between the locating portion 22 and the stopper portion 24, and this distance of the stopper portion 24 relative to the locating portion 22 can be fixed by operating a locking mechanism 20 of the stopper member 20, which is not shown. The distance can then be measured or, if appropriate, taking into account an additional amount, transferred to a stop buffer, which is then finally installed. On the stop element 20 is still a fastening device 32 can be seen, which comprises a plurality of balls 34. These balls 34 can, relative to the longitudinal direction L, be pressed radially outward, whereby a clamping with the first component 1 1 is achieved. In order for a fixing of the stop member 20 along the longitudinal direction L relative to the first component 1 1 is possible. The radial displacement of the balls 34 is realized by turning on a link 32 '. A rotation of the stop element 20 about the longitudinal direction L is prevented in particular by pins 36, which are already known from FIG. A sleeve 44 is designed to be rotatable, since an unlocking of the locking mechanism is realized via the rotational movement. LIST OF REFERENCE NUMBERS
