Description

The invention relates to a system which has a body element and a dismantling tool.

In modern motor vehicles, body elements such as doors or trunk flaps typically have various built-in parts which are at least partially arranged in an interior of the door or flap. According to a typical construction, a door has an outer panel and an inner panel, which e.g. both formed as sheet metal parts and can be connected to each other by a fold. An inner cladding is normally provided on the inside of the inner panel, e.g. is connected by screws, snap locks or the like to the inner or outer panel. If the built-in part is arranged in an interior between the inner panel and the interior lining, it is generally accessible by loosening the interior lining. Access can be more difficult within an interior space between the outer and inner panels, since the two panels cannot be detached from one another or only at a disproportionately high cost. This can be dismantled e.g. in the event of a defect in the corresponding installation part.

One of the panels, normally the inner panel, regularly has one or more access openings through which the corresponding built-in parts can be inserted and removed or through which at least access to the area of the built-in part is possible. Here, however, a problem can arise, for example, if an installation part is connected to one of the panels by means of elastic latching elements. During assembly, the installation part is brought into an intended installation position by appropriate pressure, the latching elements engaging. On the other hand, actuation of the individual locking elements is necessary for removal, i.e. these must be achieved and sufficient force must be exerted. This is particularly difficult when a latching element is arranged on a side of the built-in part facing away from the access opening, that is to say it is hidden by it. Such a situation can e.g. with a reversing camera, a switch unit or a license plate light in a tailgate. Access to the opposite side of the built-in part can be facilitated by enlarging the access opening, but this leads to an undesirable weakening of the inner panel and thus of the entire door or tailgate. In addition, access through other components, such as a wiper motor.

In view of the prior art shown, the efficient disassembly of an installation part from an interior of a body element still offers room for improvement. This applies in particular to the cases in which access to an area that is remote from an access opening of the body element is necessary.

The invention has for its object to enable an efficient disassembly of an installation part from an interior of a body element.

According to the invention, the object is achieved by a system having the features of claim 1 and by a dismantling tool having the features of claim 10, the subclaims relating to advantageous embodiments of the invention.

It should be pointed out that the features and measures listed individually in the following description can be combined with one another in any technically meaningful manner and show further refinements of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

The invention provides a system which has a body element and a dismantling tool. Instead of a system, one could also speak of a combination in which the dismantling tool is matched to the body element.

The body element is generally part of a body of a vehicle, usually a motor vehicle such as a car or truck. In particular, it can be a door or a tailgate or trunk lid. The term body element is not to be understood as restrictive in the sense of the invention. The body element has a wall that has an access opening and an interior. The wall limits the interior to the outside or at least partially surrounds it. However, it is not completely closed, but has at least one access opening through which there is a connection from the outside to the interior. The wall can be formed in one part or in several parts. For example. it can have an outer panel and an inner panel which form parts of the wall. These panels can, for example, be formed as sheet metal parts and connected to one another by folds. In this case, the interior would be formed between the panels. In particular, the access opening can be formed in the inner panel. Alternatively, the wall could also be formed, for example, by an inner panel and an inner lining which is fastened to the inner panel, the interior being formed between the inner panel and the inner lining.

Furthermore, the body element has an installation part which is at least partially arranged in the interior and which is at least indirectly connected to the wall, an unlocking element which can be actuated by pressure for releasing the installation part being arranged on a side of the installation part opposite the access opening. The built-in part can be a wide variety of components that can be arranged in the body element. For example. In the case of a trunk lid it can be a license plate light, a switch unit or a rear view camera. However, depending on the type of body element, a large number of other components are conceivable, such as sensors, actuators or the like. During assembly of the body element, the installation part can be replaced by the above-mentioned. Access opening or inserted through another opening in the interior.

In the assembled state, the built-in part is at least partially arranged in the interior, and it can in particular be arranged at least predominantly or even completely in the interior. Parts of the built-in part could also be arranged outside the interior. The built-in part is connected to the wall either directly or indirectly (that is to say via at least one intermediate element). Typically, it can be connected to the wall in a fixed position or rigidly. The corresponding connection can be released at least partially via an unlocking element which is arranged on a side of the installation part opposite the access opening. The unlocking element can be part of the built-in part, but it could e.g. also be assigned to the wall. In particular, the unlocking element can be an elastic latching element, by means of which the built-in part is latched to the wall. It is possible within the scope of the invention that the connection cannot be released solely via the unlocking element mentioned, but that, for example, a plurality of latching elements is provided, by means of which the built-in part is connected to the wall. In any case, said unlocking element must be actuated by pressure or pressurization in order to decouple or detach the built-in part from the wall. As seen from the access opening, the unlocking element is arranged on the opposite side of the built-in part, one could also say on the back. It is therefore generally at least partially covered by the built-in part and cannot be easily actuated from the side of the access opening.

In order to enable the dismantling or removal of the built-in part, a dismantling tool is provided in the system according to the invention, which can be positioned in a working position with a lever section outside the interior, with an actuating section on the unlocking element and with an intermediate contact area on an edge of the access opening , so that the unlocking element can be actuated by a lever movement around the contact area. The dismantling tool thus has a lever section, an actuating section and an abutment area located between them. The lever section is intended to be gripped by a user. It is arranged in the working position outside the interior and is therefore easy to reach and to handle for the user. The actuating section is arranged in the working position on the unlocking element or is in contact with it. It is intended to apply pressure to the unlocking element and to actuate it in this way. This is achieved in that the contact area rests against the edge of the access opening, with which this edge or the wall of which it is part forms an abutment. If there is now a lever movement with respect to the contact area, normally as a result of the user exerting a force on the lever section, a torque results within the dismantling tool, based on an axis of rotation lying in the contact area. The torque in turn leads to a compressive force or a pressure on the unlocking element in the region of the actuating section. One could say that the lever section is assigned to the power arm and the actuation section to the load arm.

It is particularly advantageous in the system according to the invention that the dismantling tool uses the edge of the access opening as an abutment, whereby (in particular with appropriate dimensioning of the sections of the dismantling tool) the unlocking element can be actuated conveniently from outside the interior. In contrast, the load on the edge of the lever process is usually so low that there is no risk of damage to the wall. This applies in particular when the wall is, for example, in the form of a shaped sheet metal part. Furthermore, the dismantling tool only requires the access opening described to enable actuation of the unlocking element arranged on the opposite side. As will become clearer with reference to preferred embodiments, the corresponding access opening does not have to be particularly large for this, so that there is no excessive weakening of the wall or the body element as a whole.

The contact area is preferably arranged between the lever section and an active section rigidly connected thereto, the active section having the actuating section. In this case, the dismantling tool can be formed predominantly by the lever section, which is arranged in the working position outside the interior, and by the active section, which is arranged in the working position in the interior. The two sections are rigidly connected to one another and are generally formed in one piece, for example from metal or a sufficiently stable plastic, for example from GRP or CFRP. The rigid connection results in an optimal and intuitive transmission of the torque from the lever section to the active section. The active section has the actuating section, which can be formed, for example, at the end of the active section. In any case, the active section is designed in such a way that, in the working position in which the contact area rests on the edge, it extends around the built-in part as far as the unlocking element. An inner contour of the active section can be adapted to an outer contour of the built-in part, i.e. it can correspond to this outer contour, taking into account a necessary space.

According to a possible embodiment, the active section has a front section adjacent to the contact area and an angled end section on which the actuating section is arranged at the end. The front section can extend from the contact area. Its length can correspond to at least a distance from the edge to the side of the installation part facing away from the access opening. The end section can connect directly or indirectly, for example with the interposition of a curved section, to which the front section adjoins. It runs at an angle to the front section, wherein each of the sections mentioned can be straight or at least sectionally curved. Although the end section is angled relative to the front section, the two sections preferably run in one plane. The lever section can also run in the same plane.

In particular, the end section can be angled at least 70 ° with respect to the front section. The speaking angle can also be at least 80 ° or even 90 °. Angles over 90 ° are also conceivable. According to some embodiments, the active section can be referred to as L-shaped. In particular, at a comparatively large angle of at least 70 °, it is preferred that the front section and the end section are connected to one another by a curved section, thereby minimizing the local load and thus the risk of the dismantling tool breaking.

The front section is advantageously inclined by less than 30 ° with respect to the lever section. In particular, the front section can run parallel to the lever section. In other words, the front section forms an extension of the lever section. In the described embodiment, in which the course of the front section differs relatively little from that of the lever section, it is generally easier for the user to handle the dismantling tool if the active section is arranged in the interior. In particular, when inserting the dismantling tool into the working position, it may be necessary or advantageous to rotate the dismantling tool about the longitudinal axis of the front section while the latter is in the interior. Such a process is explained below. Such a rotation can be accomplished more easily if the orientation of the front section corresponds approximately to that of the lever section.

With regard to the dimensioning of the individual sections of the dismantling tool, there are various possibilities, which can depend, among other things, on the design of the unlocking element and the space available outside the interior. According to an advantageous embodiment, one end of the lever section is further away from the contact area than the actuation section. Thus, with a force acting at the end of the lever section - due to the longer lever arm with respect to the contact area - a greater force results at the actuating section, in each case perpendicular to the connection vector to the contact area. Depending on the design of the unlocking element and the working section, under certain circumstances only a component, that is a part, of the force for actuating the unlocking element. The end of the lever section can, for example, be at least 1.5 times, preferably at least twice as far from the contact area as the actuating section.

In order to prevent the dismantling tool from slipping on the edge, it is preferred that the contact area has a notched contour. The contour can be concavely curved, for example, and form a type of fillet. In any case, it is provided that the edge engages in the notched structure, whereby there is an at least partial form fit, which at least makes it difficult for the dismantling tool to slide off the wall, and generally prevents it. In addition, such a notched structure can serve as an optical and / or haptic orientation aid for the user in order to determine whether the dismantling tool has been inserted far enough into the interior. So that the notch does not lead to an excessive structural weakening of the dismantling tool near the contact area, a convexly protruding or bulging contour can be formed in relation to the notched contour. In this way, approximately the same material thickness is retained despite the notch.

The actuating section advantageously has a convex rounded contour for abutment on the unlocking element. This means that the convex rounded contour lies against the unlocking element in the working position. By avoiding sharp edges in the actuating section, damage to the unlocking element can be prevented, for example. A rounded contour can also be advantageous if there are changes in position between the actuating section and the unlocking element during the lever movement.

As already described above, the working section can be provided to bypass the built-in part to a certain extent or it can be partially guided around it. According to such a configuration, the front section extends in the working position along a first side of the mounting part and the end section extends to an opposite second side, to which the unlocking element is arranged adjacent. For example. The first side can be an upper side of the installation part, so that the front section extends above along the upper side. The end section can then extend to the opposite second side, that is to the underside, the unlocking element being arranged adjacent to the underside. For example. the unlocking element could be arranged on a side surface of the built-in part arranged between the top and bottom.

The invention also provides a dismantling tool. This is intended for use for a body element, with a wall that has an access opening, and an interior, as well as an installation part arranged in the interior, wherein a pressure-actuated unlocking element for releasing the installation part is arranged on a side of the installation part opposite the access opening , According to the invention, the dismantling tool can be positioned in a working position with a lever section outside the interior, with an actuating section on the unlocking element and with an intermediate contact area on an edge of the access opening, so that the unlocking element can be actuated by a lever movement around the contact area.

All terms used here have already been explained above with reference to the system according to the invention and are therefore not explained again. Preferred embodiments of the dismantling tool according to the invention correspond to those of the system according to the invention.

Within the scope of the invention it is provided that a method for dismantling an installation part from a body element (as described above) includes a dismantling tool corresponding to a working position with a lever section with a lever section outside the interior, with an actuating section on the unlocking element and with an intermediate one Positioning area is positioned at an edge of the access opening. Furthermore, the method includes that the unlocking element is actuated by a lever movement around the contact area.

Depending on the design of the access opening, the built-in part and the dismantling tool, different movements may be necessary to bring the latter into the working position. For example. if the dismantling tool has an active section with a front section and an angled end section as described above, it can be provided that the dismantling tool is moved in the direction of the opposite side of the installation part while it is rotated about the longitudinal axis of the front section relative to the working position, for example by an angle between 70 ° and 110 ° or between 80 ° and 100 °. With such a twist, the angled end section can possibly be better guided past the installation part. If the end section is at least partially on the opposite side of the installation part, the dismantling tool is rotated into the working position. Under certain circumstances, the insertion of the knitting section into the interior cannot be arbitrary Be possible, for example. Because the access opening is comparatively small. In this case it is possible for the dismantling tool with the active section to be moved through the access opening, the movement corresponding at least in part to a rotation. The movement can also partly correspond to a translation carried out towards the interior. This can be done before, during or after the rotation. One could say that the active section can be moved through the access opening by a combined sliding and rotating movement. The rotation can take place within a plane which is given by the front section and the end section. As already mentioned above, the front section and the end section can run in one plane. The rotation takes place in this plane or around an axis that is perpendicular to this plane.

Starting from the working position, the dismantling tool is moved by the lever movement into an unlocking position in which the unlocking element is actuated. For example. when the built-in part is secured to the wall by further elements, it may be useful to secure the dismantling tool in the unlocked position. For this purpose, for example, a tension element such as a coil spring or the like can be attached to the lever section. The pulling element ensures that the dismantling tool remains in the unlocking position, while the user can, for example, manually operate additional unlocking elements (e.g. locking elements).

In the different figures, the same parts are always provided with the same reference numerals, which is why they are usually only described once.

1 shows a system according to the invention 1 with a trunk lid 20 and an associated disassembly tool 10 , For reference, the rearward X-axis of an associated vehicle, the rightward Y-axis and the upward Z-axis are shown in the figures, the position of the trunk lid 20 corresponds approximately to the closed state.

The trunk lid 20 , of which only a part is shown here, has a wall 21 on through an outside panel 22 as well as an interior panel 23 is formed. The two panels 22 . 23 are formed as sheet metal parts and connected by folds, not shown here. Between them is an interior 24 formed in which an installation part, in this case a switch unit 25 , is predominantly arranged. The switch unit 25 was through an installation opening 22.1 of the outer panel 22 in the interior 24 introduced and is inter alia by an elastic locking element 26 on the outer panel 22 secured. Optionally, additional locking elements could be provided, which are not shown here, however. If the switch unit 25 For example, due to a defect, it must be replaced through the installation opening 22.1 be removed. Through this installation opening 22.1 however, there is no access to the locking element 26 possible. Such access can only be via an inside panel 23 trained access opening 23.1 respectively.

However, this is also difficult with conventional methods, since the locking element 26 on one of the access openings 23.1 opposite back 25.1 the switch unit 25 is arranged. This is particularly true because there is a space between an upper edge 23.2 the access opening 23.1 and the switching unit 25 is too small to reach through with your hand. It should be noted in particular that the locking element 26 which is related to loosening the switch unit 25 can also be viewed as an unlocking element, can only be actuated by a pressure or a compressive force that is at least partially in the direction of the access opening 23.1 acts.

In order to do justice to this problem, it is also in 1 disassembly tool shown 10 intended. Overall, it is made in one piece and is essentially rigid, for example made of steel, cast iron or plastic. It has a straight lever section 10.1 and an approximately L-shaped knitting section 10.3 , between them an investment area 10.2 is trained. The effective section 10.3 again has one parallel to the lever section 10.1 trending front section 10.4 on by a curved intermediate section 10.5 into an end section 10.6 transforms. The end section 10.6 runs at an angle of approx. 100 ° to the front section 10.4 , End of the end section 10.6 is an operating section 10.7 with a convex rounded contour 10.8 educated. In the investment area 10.2 is a concave notched contour 10.9 formed of a convex protruding contour 10:10 opposite. Through the opposite contours 10.9 . 10:10 is around the investment area 10.2 Overall, the material thickness is similar to that in the adjacent lever section 10.1 and in the front section 10.4 , because of the notched contour 10.9 no (significant) local weakening of the dismantling tool 10 given is. The lever section 10.1 as well as the effective section 10.3 are arranged overall in one plane, which in the 1 shown position of the disassembly tool 10 corresponds to the XZ level.

The operating section 10.7 of the dismantling tool 10 is intended on the back 25.1 the switch unit 25 the locking element 26 to operate. For this, the end section 10.6 with the actuating section arranged thereon 10.7 on the back side 25.1 to be ordered. Due to the dimensioning of the access opening 23.1 , the arrangement and size of the switch unit 25 and the dimensioning of the dismantling tool 10 a special sequence of movements is necessary for this, which is subsequently based on 2 and 3 is explained.

2 shows a perspective view of the trunk lid 20 , mainly parts of the inner panel 23 and a wiper motor 27 are recognizable. The access opening 23.1 is rounded rectangular. Around the end section 10.6 to the back 25.1 to bring it through the access opening 23.1 and on a top 25.2 are guided along the switch unit. This is only possible if the disassembly tool 10 is rotated so that it is in the XY plane. A combination of rotation and translation is also required for insertion, as shown by the movement arrows in bold in 2 is indicated. A first position is an example A , a second position B and a third position C of the movement sequence shown. The rotation and translation can take place simultaneously and / or in succession. Finally in the third position C at least the effective section 10.3 inside the interior 24 arranged, the disassembly tool 10 still aligned along the XY plane.

3 shows a perspective view of the inner panel 23 with the switch unit 25 from the interior 24 out, removing the disassembly tool 10 initially in the third position C located. Now there is a pivoting process about the longitudinal axis of the front section 10.4 through which the disassembly tool 10 in a fourth position D arrives, which corresponds to a working position. The pivoting movement corresponds to an angle of approximately 90 ° and can be carried out by the user in an intuitive manner, since the front section 10.4 parallel to the handle section 10.1 runs. In other words, the user turns the handle portion 10.1 about its longitudinal axis through an angle of 90 °.

In the in 4 shown working position or fourth position D is the handle section 10.1 outside the interior 24 arranged and thus fully accessible to the user. The investment area 10.9 lies on the top edge 23.2 on, whereby the concave contour provides a certain form fit, which prevents the dismantling tool from slipping. In addition, the concave contour serves for visual and / or haptic orientation for the user, whether the dismantling tool 10 far enough into the interior 24 was introduced. The front section 10.4 extends along the top 25.2 the switch unit 25 while the end section 10.6 down along the back 25.1 towards a bottom 25.3 extends to which the locking element 26 is arranged adjacent. The operating section 10.7 lies on the locking element 26 on.

To the locking element 26 to be operated and the switch unit (and if necessary by operating further locking elements) 25 from the wall 21 to solve, the user guides by means of the lever section 10.1 a lever movement around the investment area 10.2 or the top edge 23.2 out. That is, he exerts a force on the lever section 10.1 out, leading to torque within the disassembly tool 10 and thus a force on the part of the operating section 10.7 on the locking element 26 leads. Here, the effect is enhanced by the fact that one end of the lever section 10.1 further from the investment area 10.2 is removed as the operating section 10.7 , So you can say that the power arm is longer than the load arm, in this example about twice as large. Accordingly, the force acting on the actuating section (measured perpendicular to the distance vector from the contact area 10.2 ) also twice as large as the force exerted by the user on the lever section 10.1 , the dismantling tool comes through the lever movement 10 in the in 5 fifth position or unlocking position shown e , If the locking element 26 the only one of its kind can be the switch unit 25 now down through the installation opening 22.1 from the interior 24 be pulled out. Otherwise, additional locking elements may need to be released that are not on the back 25.1 are located. In any case, it will make it easier for the user to carry out the next steps if he uses the dismantling tool 10 in the unlocked position e guaranteed. This can be done, for example, by a coil spring 30 happen on the one hand at the lever section 10.1 and on the other hand, for example, on the wiper motor 27 is attached.
