Description

Technical Field

[0001] The invention relates to a connecting structure with a protection element, a protection system for a vehicle device and a vehicle device with the connecting structure. Background Art

[0002] Vehicle design increasingly focuses on minimizing the risk of injury to pedestrians in the event of a collision. For example, the bonnet is automatically raised when a possible collision with a pedestrian is detected. Summary of the invention

[0003] The object of the present invention is to provide a connecting structure (also referred to as a connecting device) for connecting two components, a protection system, and a vehicle device with such a connecting structure, which can reduce or alleviate the mechanical load in the area of ​​the connecting structure, and in particular can reduce the collision energy caused by pedestrians, animals, or similar objects.

[0004] The present invention achieves the first object of the invention by a connection structure having the features of claim 1. The present invention achieves the second object of the invention by a protection system having the features of claim 15, and achieves the third object of the invention by a vehicle device having the features of claim 16.

[0005] A connection arrangement for connecting two components, in particular for compensating for tolerances, comprises at least one connection unit for connecting the two components and an additional protective element, which is designed to be flexible at least in sections and / or at suitable locations. The additional protective element has at least one first connection point connected to the connection unit and at least one second connection point connected to at least one of the components, wherein, in particular for forces acting on the components involved and / or the tolerance compensation device, in particular for minimum forces applied, at least one connection point and / or the protective element is designed to be flexible at least in sections and / or at suitable locations.

[0006] In particular, at least one of the connection parts and / or the protective element is designed to be flexible at least partially and / or at a suitable location, so that the connection at the at least one connection part can or will loosen itself. In this way, the connection unlocking function is realized in a simple way by the deflection of at least one connection part and / or the protective element locally and / or at a suitable location.

[0007] Preferably, the connecting unit can be configured as a tolerance compensation device with a tolerance compensation element. The tolerance compensation device can have, for example, at least one base element and a compensation element threadedly engaged with the base element, which can be moved relative to the base element by twisting to compensate for tolerances.

[0008] The first connection point and / or the second connection point can be designed to be flexible, for example, so that when a force, in particular a minimum force, is applied to the component and / or the connection unit, in particular the tolerance compensation device, the connection point will be reversibly separated, in particular reversibly loosened at a specified separation point, or irreversibly separated, in particular separated at a specified predetermined breaking point. Alternatively or additionally, the first connection point and / or the second connection point can be designed to be flexible, so that the component involved can be at least partially limited in the direction of the force relative to the connection unit, in particular relative to the tolerance compensation device and / or another component. For example, the connection unit can be connected or is connected to the protective element in a reversibly releasable manner in the area of ​​the first connection point, for example it is releasably clamped, releasably snapped or releasably screwed.

[0009] In other words: According to the invention, the object of the invention is achieved by a device for connecting two components by means of a connecting element, which is connected or can be connected to a protective element via a connecting unit. The protective element has at least one first connection point connected to the connecting element and at least one second connection point connected to at least one of the components, wherein at least one of the connection points and / or the protective element is designed to be flexible at least in certain areas and / or at appropriate locations with respect to the applied forces.

[0010] According to the present invention, the second object of the invention is achieved by a protection system for a vehicle device, in particular by a headlight, which includes the aforementioned connection structure, in particular a tolerance compensation device, or the aforementioned device for connecting two components.

[0011] According to the present invention, the third object of the invention is achieved by a vehicle device, in particular by a headlight with the above-mentioned protection system.

[0012] The following embodiments and improvements of the present invention are directed to both the connection structure, in particular the connection structure configured as a tolerance compensation device, and the aforementioned device as well as the protection system and the vehicle device.

[0013] In addition to the first connection point between the tolerance compensating element and the protective element, the connecting unit, in particular the tolerance compensating device, additionally has a second connection point between the protective element and one of the components. The protective element can be connected to the tolerance compensating element on one side by at least one first connection point and to one of the components on the other side by means of at least one second connection point.

[0014] In addition to the first connection point between one of the components and the protective element, the device has a second connection point between the protective element and the other component. The protective element can be connected to the tolerance compensation element or one of the components on one side by at least one first connection point and to one of the components or the other component on the other side by means of at least one second connection point. For example, the component can be connected or is connected to the protective element in a reversibly releasable manner in the region of the second connection point, for example, by being releasably clamped, releasably snapped in or releasably screwed.

[0015] The advantage achieved by the present invention is that by designing at least one first connection point as a flexible connection, in particular flexibly separable and / or flexibly movable, and / or designing the protective element to be reversibly movable and / or flexibly and reversibly separable, the collision energy of the pedestrian or other mechanical loads can be reduced, in particular mitigated. At the same time, such a flexible connection can reduce the degree of damage to components (such as the main headlights) or even avoid component damage, because in the event of a collision, including a collision with a fixed obstacle, these components will be avoided, in particular moved away from the collision area. In this way, repair costs can be reduced or even completely eliminated. In addition, for a vehicle with such a connection structure, due to the use of a flexible, in particular reversibly loose connection, it can be included in a more affordable vehicle insurance class.

[0016] Preferably, the connecting unit, in particular the tolerance compensating element, and the protective element are provided to be reversibly connected to one another in the region of the first connecting point, in particular by clamping and / or snapping.

[0017] Alternatively or additionally, at least one component and the protective element are provided in the region of the second connection point so as to be reversibly connectable to one another, in particular by clamping and / or snapping.

[0018] The protective element can be designed, for example, as a spring plate. Optionally, the protective element can include an elastic section. A component or a connecting unit, in particular a tolerance compensation element, can have a slope. Conversely, the protective element can have a slope and a component or a connecting unit, in particular a tolerance compensation element, can be designed as a spring plate in a section or include an elastic section.

[0019] In particular, the protective element can be arranged on one side in a fixed or detachable manner on the connecting unit, in particular the tolerance compensating element, and on the other side can be detachably connected to one of the components.

[0020] In another embodiment, the protective element is designed as a spring element. In addition, the protective element and / or at least one of the components is provided with an integrated nut element.

[0021] Furthermore, the protective element can have a snap-on element or a clamping element at the free end, for example. The ramp can be designed accordingly, in particular for the free end. For example, the ramp can have a flatter slope in the connection direction than in the opposite opening direction. In this way, the protective element can be snapped into the ramp in a reversibly locked manner in the connection direction by means of the snap-on element or the clamping element. In order to loosen or unlock the connection, an opening force is required that overcomes the steep slope of the ramp, which loosens the snap-on element or the clamping element from the engaged state on the ramp.

[0022] Additionally, at least one compression rib can be provided in order to achieve a seamless connection of the two components (in a reversible manner). For example, a first compression rib, in particular an arc-shaped compression bridge, can extend in the vertical direction in order to compensate for tolerances in the vertical direction. A second compression rib, in particular an arc-shaped compression bridge, can extend in the transverse direction in order to compensate for tolerances in the transverse direction. In this way, the protective element is free of gaps in at least two directions, thereby achieving a low-noise support.

[0023] Furthermore, a connecting element, in particular a connecting screw or a connecting pin, for example a threaded pin, can be provided, which is connected or can be connected to the protective element via the connecting unit, in particular the tolerance compensation device.

[0055] Figure 1 A first exemplary embodiment of a connection arrangement 300 is schematically shown in exploded and side views, having a connection unit 300 . 1 designed as a tolerance compensation device 1 with a tolerance compensation element 1 . 1 and a protective element 1 . 2 (also called pedestrian protection unit or traffic safety adapter).

[0056] The connecting unit 300.1 can be designed as a tolerance compensation device 1. Alternatively, Fig.63 As shown, the connecting unit 300 . 1 can also be designed as a screw connection 300 . 2 which is additionally provided with a protective element 1 . 2 .

[0057] Hereinafter, the connection unit 300.1 will be Figures 1 to 9 As an example, the tolerance compensation device 1 shown in FIG. Figures 10 to 56 The tolerance compensation device 100 shown in FIG. Figures 57 to 62 The tolerance compensation device 100 shown in the figure is taken as an example and Fig.63 The bolt connection 300.2 is shown as an example.

[0058] Figure 2 The tolerance compensation device 1 with the protective element 1 . 2 is schematically shown in an exploded view and in a perspective view.

[0059] The tolerance compensation device 1 is used to connect two components 2 and 4 (in Figure 5 ), while compensating for tolerances 201, in particular axial tolerances 201 (in Figure 6 ).

[0060] In a vehicle, the tolerance compensating device 1 is used, for example, to connect two vehicle components, such as a headlight and a vehicle trim, in particular to connect a front headlight and a vehicle trim (also called vehicle skin), while compensating for axial tolerances 201 and / or radial tolerances.

[0061] In addition to axial tolerance compensation by means of the tolerance compensation element 1.1, the tolerance compensation device 1 is configured to provide pedestrian protection by means of the protective element 1.2. The protective element 1.2 and the tolerance compensation element 1.1 are configured to interact in the assembled state so as to reduce the impact energy applied to at least one of the components 2, 4 in the event of an impact with a pedestrian or other object. By reducing the impact energy, pedestrian protection is achieved in a simple manner and personal injuries are minimized.

[0062] The tolerance compensation element 1.1 comprises at least one basic element 1.1.1, in particular a hollow cylindrical sleeve with an internal or external thread, a fixing element 1.1.2, such as a clamping arm or a stop arm, which is separate or integrated on the basic element 1.1.1 or the compensation element 1.1.3, and a compensation element 1.1.3 which forms a threaded connection with the basic element 1.1.1 and can be moved relative to the basic element 1.1.1 by torsion to compensate for the axial tolerance 201.

[0063] As described earlier in DE 10 2023 205 661.5, the tolerance compensating element 1.1 is a conventional compensating element 1.1.3.

[0064] The protection element 1.2 comprises at least one first connection point 1.2.1 connected to the tolerance compensation element 1.1 and at least one first connection point 1.2.1 connected to the first component 2 (at Figure 5 At least one second connection location 1.2.2 connected).

[0065] The first connecting point 1.2.1 is designed, for example, as a seat 1.2.3, in particular as a stop seat or clamping seat, for fastening the element 1.1.2 of the tolerance compensating element 1.1.

[0066] The second connection point 1.2.2 of the protective element 1.2 to the first component 2 (eg, the vehicle outer skin or vehicle trim) is designed as a flexible connection. In particular, the second connection point 1.2.2 is designed to be flexible at least partially and / or at appropriate locations when forces are applied.

[0067] For example, in the event of a collision and the resulting application of forces, especially minimal forces, such as Figure 7 In detail, the second connection point 1.2.2 is reversibly separable. Additionally or alternatively, the first component 2 can be moved at least to a limited extent in the force direction 200 relative to the further second component 4 and the tolerance compensation device 1 when a force is applied.

[0068] In other words: in addition to the first connection point 1.2.1 between the tolerance compensating element 1.1 and the protective element 1.2, the tolerance compensating device 1 additionally has a second connection point 1.2.2 between the protective element 1.2 and the first component 2.

[0069] The protective element 1.2 can be connected to the tolerance compensating element 1.1 on one side by at least one first connection point 1.2.1, and can be connected to the first component 2 on the other side by means of at least one second connection point 1.2.2. By designing the second connection point 1.2.2 as a flexible connection, in particular a flexibly movable and / or flexibly separable connection, the collision energy of the pedestrian in the force direction 200 can be reduced.

[0070] The protective element 1.2 is designed in particular as a one-piece component, in particular as an injection-molded component. The protective element 1.2 comprises a base unit 1.2.4. The base unit 1.2.4 can be designed, for example, as a base plate or a chassis.

[0071] The first connection point 1.2.1 projects perpendicularly on one side from the base unit 1.2.4 in one direction, in particular in the direction of the tolerance compensating element 1.1, whereas the second connection point 1.2.2 projects perpendicularly in the opposite direction, in particular in the direction of the first component 2.

[0072] The first connection point 1.2.1 is designed, for example, as a fastening sleeve 1.2.4.1 which has a seat 1.2.3 for a fastening element 1.1.2 of the tolerance compensating element 1.1, in particular a latching arm with a hook.

[0073] The second connection part 1.2.2 is designed to be flexible. The second connection part 1.2.2 can, for example, include a certain number of flexible fixing arms 1.2.5, in particular flexible stop arms with hooks or clamping arms with clamping hooks.

[0074] like Figure 2 As shown, the protective element 1.2 can comprise, as a first connection point 1.2.1, a plurality of supports 1.2.3, in particular two supports 1.2.3 located opposite each other for fixing the element 1.1.2.

[0075] Furthermore, the protective element 1.2 may have a plurality of second connection locations 1.2.2, each of which includes a plurality of fixing arms 1.2.5, in particular a group of an even number of fixing arms 1.2.5. The second connection locations 1.2.2 and the group of fixing arms 1.2.5 are arranged on the basic unit 1.2.4 in a symmetrically distributed manner. For example, for a rectangular basic unit 1.2.4, the second connection locations 1.2.2 are arranged at each corner.

[0076] Figure 3The tolerance compensating device 1 is schematically shown in a side view in an assembled or connected state (for example in the delivery state), wherein all components of the tolerance compensating device 1 are captively connected to one another.

[0077] In the assembled state, the fastening element 1 . 1 . 2 , in particular a hook or a clip, of the tolerance compensating element 1 . 1 is arranged and fixed in a form-fitting and / or force-fitting manner in the seat 1 . 2 . 3 of the protective element 1 . 2 .

[0078] Figure 4 The tolerance compensation device 1 is schematically shown in an exploded sectional view before being mounted on a first component 2. The first component 2 can be, for example, a headlight, in particular a front headlight.

[0079] The first component 2 comprises openings 2.1 for supporting the fixing arms 1.2.5 of the protection element 1.2. In particular, the first component 2 comprises openings 2.1 corresponding to the number of groups of fixing arms 1.2.5, so as to pre-install and pre-position the tolerance compensation device 1 on the first component 2.

[0080] The opening 2.1 is designed as a through hole, for example. In particular, the opening 2.1 is designed so that when the fixing arm 1.2.5 is inserted, the tolerance compensation device 1 and the first component 2 can move in a limited manner, especially in a radial direction and / or an axial direction, and support and fix each other. For example, in order to enable axial movement, the length of the fixing arm 1.2.5 is designed to be greater than the length of the opening 2.1. In order to enable limited radial movement, the opening 2.1 is designed to be greater than the outer circumference of the fixing arm 1.2.5 inserted into the corresponding opening 2.1.

[0081] The fixing arm 1.2.5 is designed as a stop arm or a clamping arm, for example, and comprises a hook or a clamping hook at the free end. The tolerance compensation element 1.1 and the tolerance compensation device 1 preassembled with the protection element 1.2, especially fixedly connected together, are inserted into the opening 2.1 of the first component 2 by means of the fixing arm 1.2.5, especially arranged and fixed in a force-locking manner, and can be limitedly moved, especially in the axial and / or radial directions.

[0082] In other words: the first component 2 is arranged in a displaceable manner relative to the tolerance compensation device 1 , or vice versa, and is connected thereto.

[0083] Figure 5 The tolerance compensating device 1 is schematically shown in an exploded cross-sectional view after it has been mounted on the first component 2 and before a second component 4 is to be mounted on the tolerance compensating device 1 .

[0084] The second component 4 has rigidity, and may be, for example, a vehicle outer skin or a vehicle trim panel.

[0085] The second connection point 1.2.2 between the tolerance compensation device 1 and the first component 2 is designed as a clamping connection or a snap connection. In addition to the clamping connection or snap connection between the fixed arm 1.2.5 and the opening 2.1, it can also be designed to adopt other suitable loose connections, especially loose riveting connections, bolt connections or similar connections.

[0086] In order to achieve flexibility, the second connection part 1.2.2 can be designed as a limited non-fixed connection or a limited movable connection, especially a partially movable connection, and has a gap 10 (in Figure 7 In addition to a limited loose connection or a limited movable connection, the second connection part 1.2.2 can also have a predetermined breaking point 1.2.6. The predetermined breaking point 1.2.6 is particularly designed in the contact area 1.2.8 between the protective element 1.2 and the first component 2. The predetermined breaking point 1.2.6 can be designed to correspond to the notch 1.2.7 in the fixed arm 1.2.5.

[0087] Figure 6 The tolerance compensation device 1 is schematically shown in cross section in a state connected to two components 2, 4 and compensating for axial tolerances 201 between the two components 2, 4. The tolerance compensation device 1 together with the components 2, 4 forms a pedestrian protection system 20 in the final installed state, thereby reducing collision energy.

[0088] In the connected state, the connecting element 6, in particular a screw, passes through the component opening 4.1 of the second component 4 and is screwed into the tolerance compensation device 1, in particular the nut element 8. The nut element 8 can be fixed, in particular arranged and positioned in a rotationally fixed manner in the base unit 1.2.4 of the protective element 1.2, in particular in the sleeve 1.2.4.1. Optionally, the nut element 8 can be designed as a nut thread integrated in the base unit 1.2.4 or as a nut element 8 injection-molded in the base unit 1.2.4.

[0089] By tightening the connecting element 6 , any axial tolerance 201 with respect to the second component 4 is compensated by means of the tolerance compensation device 1 and a fixed connection is produced between the components 2 and 4 .

[0090] Figure 7 The cross-sectional view schematically shows Figure 6 2 , and a tolerance compensation device 1 with a flexible second connection point 1 . 2 . 2 , which is located between the first component 2 and the protective element 1 . 2 of the tolerance compensation device 1 .

[0091] When a force is applied in the force direction 200, both the contact area 1.2.8, in particular the cross-sectional area between the component 2 and the protective element 1.2, and the notch 1.2.7 are designed to be flexible and can optionally be designed as a predetermined breaking point 1.2.6.

[0092] When the tolerance compensation device 1 is assembled or installed with the protective element 1.2, a gap 10 (also called a collision gap) can be provided between the protective element 1.2 (especially its base unit 1.2.4) and the first component 2 (especially the headlight).

[0093] When or after a pedestrian collides with the first component 2 in the force direction 200, the force from the first component 2 acts on the second connection point 1.2.2, in particular on the contact area 1.2.8, so that the notch 1.2.7 designed as the predetermined breaking point 1.2.6 breaks. Then, the first component 2 moves in the force direction 200, in particular in the direction of the vehicle inner side, until it contacts the stopper 1.2.9 of the base unit 1.2.4 and compensates the gap 10 (= a gap).

[0094] In addition to the notches 1.2.7, a cross section of the first component 2 or another suitable surface or material reduction can also be provided and correspondingly designed as a predetermined breaking point 1.2.6.

[0095] Figure 8 The top view schematically shows the Figure 6 The tolerance compensation device 1 is shown.

[0096] In order to reduce the impact energy in a controlled manner in the force direction 200, the first component 2 can have a lateral constriction 2.2. Fig. 9 As shown, in the event of a collision, these narrow spots 2.2 will pass through guides 1.2.10 embedded in the base unit 1.2.4 of the tolerance compensation device 1, in particular the protective element 1.2.

[0097] Fig. 9 The first component 2 and the basic unit 1.2.4 of the protective element 1.2, which is designed, for example, as a base plate, are schematically shown in a sectional view in the region of the lateral constriction 2.2 of the first component 2 and the guide 1.2.10 in the basic unit 1.2.4.

[0098] For example, the guide 1.2.10 is designed as an edge or flange in the base unit 1.2.4. The guide 1.2.10 extends in the force direction 200 and expands in the force direction 200. In other words: the distance 1.2.11 formed between the side guides 1.2.10 increases in the force direction 200.

[0099] A set of four fixing arms 1.2.5 with gaps 1.2.12, in particular radial gaps 1.2.12, is arranged in each opening 2.1 of the first component 2. The gaps 1.2.12 in particular allow the fixing arms 1.2.5 to be flexible, so that they can be easily inserted into the opening 2.1 and fixed therein in a form-fitting and / or force-fitting manner, in particular snapped or clamped therein. Furthermore, in the event of a collision with one of the components 2, 4, resulting in the application of a force, for example in the force direction 200, the gaps 1.2.12 also allow the second connection point 1.2.2 to be flexible.

[0100] Fig.10 A further embodiment of a connecting structure 300 is schematically shown in an exploded view, which has a connecting unit 300 . 1 designed as a tolerance compensation device 100 (hereinafter referred to as further tolerance compensation device 100 ).

[0101] The difference between the tolerance compensating device 1 and the tolerance compensating device 1 lies in the second connection point 1.2.2 and the base unit 1.2.4. The second connection point 100.2.2 of the tolerance compensating device 100 has a connecting bolt 100.2.5 for connecting the protective element 100.2 and the first component 2 instead of the fixing arm 1.2.5 of the second connection point 1.2.2. The tolerance compensating device 100 has a material reduction 100.2.7 in the protective element 100.2 as a predetermined breaking point 100.2.6 instead of the notch 1.2.7 and the contact area 1.2.8 as the predetermined breaking point 1.2.6.

[0102] As mentioned above, the tolerance compensating element 1.1 consists of a base element 1.1.1 and a compensating element 1.1.3 as well as a fixing element 1.1.2. As mentioned above, the first connection point 1.2.1 consists of a fixing element 1.1.2 and a support 100.2.3. In the delivery state, the tolerance compensating element 1.1 can be pre-assembled and pre-fixed on the protective element 1.2 or 100.2 by means of the fixing element 1.1.2, so that it can be fixed in place in a way that it cannot be lost.

[0103] The modified second connection point 100.2.2 comprises a guide sleeve 100.2.13 for guiding the connecting screw 100.2.5 and in the delivery state the connecting screw 100.2.5 can optionally be pre-mounted, pre-fixed and captively fixed to the tolerance compensation device 100.

[0104] Similar to the basic unit 1.2.4, the basic unit 100.2.4 is designed as a base plate or a disk, from which two connection points 100.2.1 and 100.2.2 protrude vertically in opposite directions. For supporting the tolerance compensating element 1.1, the basic unit 100.2.4 similarly has a sleeve 100.2.4.1.

[0105] Furthermore, the basic unit 100.2.4 has a contact region 100.2.8 in the direction of the first component 2, in order to lie flat on the first component 2 similar to the basic unit 1.2.4.

[0106] Fig.11 The exploded view and perspective view schematically show Fig.10 Another tolerance compensating device 100 is shown.

[0107] The basic unit 100.2.4 has one or more predetermined breaking points 100.2.6, in particular one or more material reductions 100.2.7 in the area between the sleeve 100.2.4.1 and the guide bushing 100.2.13.

[0108] The material reduction 100.2.7 can be designed, for example, as a notch on the edge of the plate-like basis unit 100.2.4. Additionally or alternatively, the material reduction 100.2.7 can be designed as a through hole and / or a through opening.

[0109] Fig.12 The assembly is schematically shown in a side view, in particular in the pre-assembled state. Fig.10 Another tolerance compensating device 100 is shown (e.g. in the delivery state), in which all components of the tolerance compensating device 100 are connected to one another in a captive manner. The connecting screw 100.2.5 is arranged in a captive manner and fixed in the guide sleeve 100.2.13. The fixing element 1.1.2 of the tolerance compensating element 1.1 is arranged and fastened in a positive and / or non-positive manner in the support 100.2.3 of the protective element 100.2.

[0110] Fig.13 The cross-sectional view schematically shows the Fig.12 Another tolerance compensating device 100 is shown. The tolerance compensating device 100 is placed on the first component 2 together with the tolerance compensating element 1.1 and the protective element 100.2. In particular, the tolerance compensating device 100 is inserted or pushed into the fixing seat 2.3 of the first component 2.

[0111] In order to pre-fix the connecting bolt 100.2.5 in the guide sleeve 100.2.13, the guide sleeve has a fixing shoulder 100.2.14. The fixing shoulder 100.2.14 and the connecting bolt 100.2.5 have corresponding surfaces and / or surface contours, which enable a releasable non-positive and / or positive connection.

[0112] Fig.14The schematic cross-sectional exploded view shows a first component 2 which has been pre-assembled and is ready to be mounted on the tolerance compensation device 100 before the second component 4, in particular a fixed or rigid structural element (such as the outer skin of a vehicle) is installed. Fig.12 The tolerance compensation device 100 is shown.

[0113] In order to pre-install and pre-fix the tolerance compensation device 100 on the first component 2 , the connecting screw 100 . 2 . 5 is screwed into the nut element 2 . 4 which is arranged in a rotationally fixed manner in the opening 2 . 1 of the first component 2 or is integrated therein, in particular injection-molded therein.

[0114] Fig.15 A further tolerance compensation device 100 is schematically shown in cross section, which is connected to two components 2, 4 and compensates for axial tolerances 201 between the two components 2 and 4. Tolerance compensation device 100 together with components 2, 4 forms a pedestrian protection system 20 in the final installed state, thereby reducing collision energy.

[0115] In the connected state, the connecting element 6, in particular a screw, passes through the component opening 4.1 of the second component 4 and is screwed into the tolerance compensation device 100, in particular the nut element 8. The nut element 8 can be fixed, in particular arranged and positioned in a rotationally fixed manner in the base unit 100.2.4 of the protective element 100.2, in particular in the sleeve 100.2.4.1. Optionally, the nut element 8 can be designed as a nut thread integrated in the base unit 100.2.4 or as a nut element 8 injection-molded in the base unit 100.2.4.

[0116] By tightening the connecting element 6 , any axial tolerances 201 with respect to the second component 4 are compensated by means of the further tolerance compensation device 100 and a fixed connection is produced between the components 2 and 4 .

[0117] Fig.16 The cross-sectional view schematically shows Fig.15 2 . Another tolerance compensation device 100 is shown, and has a flexible second connection point 100 . 2 . 2 , which is located between the first component 2 and the protective element 100 . 2 .

[0118] When the tolerance compensation device 1 is assembled or installed with the protective element 1.2, a similar gap 10 (also called collision gap) can be designed between the protective element 100.2 (especially its base unit 100.2.4) and the first component 2 (especially the headlight).

[0119] Fig.17 The top view schematically shows the Fig.16Another tolerance compensation device 100 is shown, which has a constriction 2.2 or a material reduction 100.2.7 as a predetermined breaking point 100.2.6 in the base plate of a base unit 100.2.4 designed as a protective element 100.2, while the second component 4 is not drawn for better illustration.

[0120] When or after a pedestrian collides with the first component 2 in the force direction 200, the force acts from the first component 2 on the second connection point 100.2.2, in particular on the connecting bolt 100.2.5, so that the material reduction portion 100.2.7 designed as the preset breaking point 100.2.6 breaks. Next, the first component 2 moves in the force direction 200, in particular in the direction of the vehicle inner side, until it contacts the stopper 100.2.9 of the base unit 100.2.4 and compensates the gap 10 (= a gap).

[0121] As the predetermined breaking point 100.2.6, other suitable surfaces or material reductions can also be provided in the basic unit 100.2.4 and / or on the connecting bolt 100.2.5 and designed accordingly.

[0122] Fig.18 The top view schematically shows the Fig.17 A further tolerance compensation device 100 is shown, which in the protective element 100 . 2 , in particular in the base unit 100 . 2 . 4 , has a material reduction 100 . 2 . 7 .

[0123] In order to reduce the impact energy in a controlled manner in the force direction 200, the component 2 can have a lateral constriction 2.2 similar to the tolerance compensation device 1. Fig.19 As shown, in the event of a collision, these narrowings 2.2 pass through guides 100.2.10 embedded in a base unit 100.2.4 of a further tolerance compensation device 100, in particular a protective element 100.2.

[0124] Fig.19 The first component 2 and a base unit 100 . 2 . 4 of a protective element 100 . 2 , which is designed, for example, as a base plate, are schematically shown in a sectional view in the region of a lateral constriction 2 . 2 of the first component 2 .

[0125] For example, similar to the first embodiment, the guide 100.2.10 is designed as an edge or flange in the base unit 100.2.4. The guide 100.2.10 extends in the force direction 200 and expands in the force direction 200. In other words: the distance 100.2.11 formed between the side guides 100.2.10 will increase in the force direction 200.

[0126] The connecting screw 100 . 2 . 5 is screwed into the opening 2 . 1 in the first component 2 .

[0127] Figures 20 to 28 Different views of an exemplary embodiment of a connection arrangement 300 are schematically shown, which has a connection unit 300 . 1 designed as a tolerance compensation device 100 having a protective element 100 . 2 with a reversibly releasable separation point 100 . 1 .

[0128] Fig. 20 The protective element 100 . 2 is shown tensioned in the component 2 .

[0129] The tolerance compensating device 100 differs from the aforementioned tolerance compensating devices 1 , 100 in that the connecting points 100 . 2 . 1 and 100 . 2 . 2 are designed to be reversibly detachable.

[0130] In this way, components 2 and 4 can be reused when necessary. The protective element 100.2 can also be reused. For better illustration, only component 2 is shown. Figure 6 As shown, the component 4 is fastened to the tolerance compensation device 100 .

[0131] The protective element 100.2 is designed as a carriage 100.3. As connection points 100.2.1 and 100.2.2, the protective element 100.2 comprises a detachable connection, in particular a detachable latching connection.

[0132] For example, the protection element 100.2 comprises a first stop element 100.4 and a second stop element 100.5. For example, the two stop elements 100.4 and 100.5 are designed as flexible arms, in particular elastic arms. The two stop elements 100.4 and 100.5 act in opposite directions.

[0133] The first stop element 100.4 acts in the spatial direction -z. The second stop element 100.5 acts in the spatial direction +z. Optionally, a stop can be provided in a manner not shown in detail, which acts in both spatial directions +z, -z and provides protection in both directions.

[0134] As soon as a mechanical load indicated by arrow 202, such as a collision, occurs on component 2 (e.g., a headlight), the carriage 100.3 moves in the spatial direction +z, because the first stop element 100.4 can be released from the stop seat 2.5 on component 2. Since the second stop element 100.5 is flexible or pliable and a gap 100.6 is provided for the second stop element 100.5 in another stop seat 2.6 of component 2, the carriage 100.3 can move in the spatial direction +z by the distance of the gap 100.6.

[0135] Fig.21 The carriage 100 . 3 is shown with the tolerance compensation device 100 pre-installed.

[0136] The carriage 100.3 has a rectangular bottom area 100.3.1, which is arranged to guide the carriage 100.3 during the compensation action when subjected to a mechanical load indicated by the arrow 202. Above the bottom area 100.3.1, the carriage 100.3 has an inclined side wall 100.3.2, which is also arranged to guide the carriage 100.3 during the compensation action, while additionally avoiding axial disengagement. A first stop element 100.4 is arranged on at least one side wall 100.3.2. The first stop element 100.4 protrudes outwards from the side wall 100.3.2. For example, the first stop element 100.4 is designed as a flexible stop arm 100.4.1 with a hook 100.4.2. A second stop element 100.5 is arranged on the end face 100.3.3. The second stop element 100.5 protrudes outwards, in particular forwards, from the end face 100.3.3. For example, the second stop element 100.5 is designed as a flexible stop arm 100.5.1 with a hook 100.5.2.

[0137] Fig. 22 The carriage 100.3 is shown in a perspective view from the rear. The first stop element 100.4 is designed as a stop arm 100.4.1 which is at an angle to the side wall 100.3.2.

[0138] Fig.23 and 24 A guide 100 . 7 is shown which is provided for the carriage 100 . 3 and is a component of the first component 2 , in particular designed or arranged on the first component 2 .

[0139] For the bottom area 100.3.1 of the carriage 100.3, the guide 100.7 has a corresponding bottom surface 100.7.1. For the inclined side walls 100.3.2 of the carriage 100.3, the guide 100.7 has a corresponding side surface 100.7.2. In addition, for the stop elements 100.4 and 100.5 of the carriage 100.3, the guide 100.7 has corresponding counter-stop elements 100.7.3 and 100.7.4. The first counter-stop element 100.7.3 is designed as a flange on the inner side of one of the side walls 100.3.2. The second counter-stop element 100.7.4 is designed as a notch in the bottom surface 100.7.1.

[0140] Fig.25 The carriage 100 . 3 with the pre-installed tolerance compensation device 100 is shown in the mounted state on the guide 100 . 7 of the second component 2 .

[0141] Fig.26A protective element 100.2 designed as a carriage 100.3 is shown, which is fixed via releasable connection points 100.2.1 and 100.2.2 between counter-stop elements 100.7.3 and 100.7.4 of component 2 and thus to component 2. Component 4 and tolerance compensation device 100 are not shown.

[0142] Fig. 27 A component 2 is shown, which is subjected to a force indicated by arrow 202 due to a mechanical load, such as a collision exerted on the component 2. The first connection point 100.2.1 is designed to be releasable. The first stop element 100.4 is designed to be released from the first connection point 100.2.1, in particular from the stop seat 2.5, when the force indicated by arrow 202 on the component 2 exceeds a predetermined release force. In this way, the component 2 or the carriage 100.3 is released so that they can move relative to each other, and the movement distance is in particular the gap 100.6 on the separation point 100.1, in particular in the stop seat 2.6.

[0143] For example, the release force can be specified substantially by the flexibility of the first stop element 100.4, in particular the spring stiffness of the stop arm 100.4.1 and / or the contact angle of the stop element 100.4.

[0144] Fig.28 The first stop element 100.4 is shown in the released state, wherein the stop lug 100.4.2 has been released from the stop seat 2.5 and the component 2 has been released. The second stop element 100.5 limits the relative movement of the component 2 in the -z direction due to the gap 100.6 in the stop seat 2.6.

[0145] Figures 29 to 33 Different views of alternative separation points 100 . 1 of a connecting unit 300 . 1 designed as a tolerance compensation device 100 are schematically shown.

[0146] Fig.29 A compression spring element 100.8 is shown, which can additionally or alternatively replace the flexible stop arm 100.4.1. The release force here depends only partially on the spring force of the first stop element 100.4, or not at all on it, but on the pressure of the compression spring element 100.8.

[0147] Fig.30The component 2 and the protective element 100.2 are shown in the fixed state without gaps in the longitudinal direction x and in the transverse direction y, in particular by means of the flexible stop elements 100.4, 100.5 in a tensioned and therefore gap-free state. The protective element 100.2 is held tensioned in the component 2 by means of the flexible stop elements 100.4, 100.5 and the mutually corresponding surfaces, in particular the inclined side wall 100.3.2 and the inclined component wall 2.7, in particular in all three spatial directions x, y, z, in particular in the longitudinal direction x, in the transverse direction y and in the vertical direction z (in Fig. 20 Keep tension on the ).

[0148] By means of the flexible stop elements 100.4, 100.5, the tolerance compensation device 100 can be fixed in the component 2 without play and stationary by means of the protective element 100.2 until a predetermined release force is reached. In this way, vibrations when supporting the component 2 are avoided or at least reduced, for example, in the case of a component 2 designed as a headlight, so-called headlight vibration can be avoided or at least reduced.

[0149] Flexible stop elements 100.4, 100.5 (in Fig. 20 ) generates a force that tensions the protective element 100.2 without play in three spatial directions x, y, z.

[0150] exist Fig.30 In the embodiment, a force having a Y component and an X component is applied by the first stop element 100.4, so that there is no gap in the spatial directions x and y. In addition, the applied force is supported by the corresponding inclined surfaces of the side wall 100.3.2 and the component wall 2.7.

[0151] The applied force can be generated by the flexible first stop element 100.4. Optionally, at least one separate spring element (not shown in detail) can also be provided for each spatial direction x, y, z, for example a curved leaf spring or the like.

[0152] Fig.31 The protective element 100.2 is shown to be tensioned without play in the spatial direction z by means of the second stop element 100.5. In order to tension the carriage 100.3 without play in the spatial direction z, the second stop element 100.5 is fixed in the stop seat 2.6 in a prestressed manner ("overstressed").

[0153] Fig.32 A further embodiment is shown for a play-free or tensioned fixation in the spatial direction z. In addition to the second stop element 100.5, an elastic element 100.9 is additionally provided, in particular a leaf spring or the like, which fixes the second stop element 100.5 in the stop seat 2.6 in a prestressed manner with a specified force.

[0154] Figures 33 to 36 Schematically shown are different views of another embodiment of a tolerance compensation device 100, having a protective element 100.2 with a reversibly releasable separation point 100.1. The carriage 100.3 has a recess 100.10, in which a fixing spring 100.11, in particular an omega-type spring (in Fig.33 ), for supporting a releasable fixing element 100.12, in particular a fixing pin or a fixing bolt or a similar element (such as Fig.34 shown). Fig.35 The protective element 100 . 2 is shown in the normal position, such that the components 2 and 4 are in the connected position, in which they are connected to one another via the tolerance compensation device 100 and the protective element 100 . 2 in a play-free, in particular tensioned manner, while compensating for tolerances. Fig.36 The protective element 100.2 is shown in a released or released state after the connection has been mechanically loaded, wherein the separation point 100.1 has been reversibly released, for which purpose the fixing element 100.12 has been released from the fixing part in the fixing spring 100.11.

[0155] Figures 37 to 38 Different views of a further exemplary embodiment of a connection arrangement 300 are schematically shown, which has a connection unit 300 . 1 designed as a tolerance compensation device 100 having a protective element 100 . 2 with a reversibly releasable separation point 100 . 1 .

[0156] The protection element 100.2, in particular the slide 100.3, is designed in multiple sections, for example, in two sections. Fig.37 In the figure, a separation point 100.1 is shown in the closed position and is formed between the two carriage parts 100.3.4 and 100.3.5. The separation point 100.1 comprises a fixing arm 100.13, which is fixedly arranged on one of the carriage parts 100.3.4 and releasably fixed on the other carriage part 100.3.5. For this purpose, the carriage part 100.3.5 can, for example, comprise a snap-in groove 100.3.6, into which a stop lip 100.13.1 of the fixing arm 100.13 releasably snaps.

[0157] Fig.38 The separation point 100.1 is shown in a loosened position after a mechanical load indicated by an arrow 202 is applied to component 2, wherein the mechanical load exceeds the retaining force of the fixed arm 100.13 in the slot 100.3.6, causing the fixed arm 100.13 to loosen and release from the slot 100.3.6, and the slide parts 100.3.4 and 100.3.5 to separate from each other.

[0158] Figures 39 to 43Schematically shown are different views of an exemplary embodiment of a device 300 for connecting at least two components 2 , 4 (also referred to as connecting structure 300 ) having an above-described protective element 100 . 2 with at least one reversibly releasable separation point 100 . 1 .

[0159] exist Fig.39 and 40 In the embodiment, the device 300 is a connecting unit 300.1, which comprises a separate spacer element 301 instead of the tolerance compensation device 1, 100. The spacer element 301 is designed as a hollow cylindrical connecting pin. The spacer element 301 is arranged similarly to the tolerance compensation device 100 (1) and is fixed in the support 100.2.3 (1.2.3) of the protective element 100.2 (1.2). In addition, as Fig.40 As shown, a nut element 8 with an internal thread is arranged in the support 100.2.3 (1.2.3). As described above for the tolerance compensation device 100, the reversible fixing function of the protective element 100.2 is realized in a similar manner by means of stop elements 100.4, 100.5 at at least two separation points 100.1 of the connection parts 100.2.1 and 100.2.2.

[0160] exist Figures 41 to 43 In the embodiment, the device 300 comprises as a connection unit 300.1 a distance extension 302 integrated in the protection element 100.2 instead of a separate spacing element 301. The support 100.2.3 has an internal thread 303 for a connection element 6, in particular a screw or a threaded pin, instead of a nut element 8. Fig.43 The device 300 is shown in the installed state, wherein the two components 2 and 4 are flexibly connected to each other with the help of the device 300 and the connecting element 6 at least partially and / or at suitable positions with the help of the protective element 100.2 (especially the slide 100.3) and the flexible stop elements 100.4, 100.5, in particular they are releasably connected together via the separation point 100.1.

[0161] Figures 44 to 56 Different views of a further exemplary embodiment of a connecting structure 300 are schematically shown, which has a connecting unit 300 . 1 designed as a tolerance compensation device 100 for connecting two components 2 , 4 .

[0162] Fig.44 The tolerance compensating device 100 is shown in a partially exploded view before being mounted on the component 2 . Fig.45 The tolerance compensating device 100 is shown mounted on a component 2 .

[0163] The tolerance compensation device 100 comprises a tolerance compensation element 1.1 and a protection element 1.2.

[0164] The tolerance compensating element 1.1 comprises at least a base element 1.1.1 and a compensating element 1.1.3 which is in threaded engagement with the base element 1.1.1 and is torsionally movable relative to the base element 1.1.1 in order to compensate for tolerances.

[0165] The protective element 1.2 comprises at least a first connection point 1.2.1 connected to the tolerance compensation element 1.1 and a second connection point 1.2.2 connected to the component 2. In this case, the second connection point 1.2.2 is designed to be flexible at least in places and / or at appropriate locations when a force is applied.

[0166] like Fig.45 As shown, the second connection location 1.2.2 is designed as a reversibly detachable separation point 100.1.

[0167] Preferably, the component 2 and the protective element 1 . 2 are provided so as to be reversibly connected to one another in the region of the second connection point 1 . 2 . 2 , in particular by means of clamping and / or snapping.

[0168] Alternatively or additionally, the tolerance compensating element 1 . 1 and the protective element 1 . 2 are provided in the region of the first connecting point 1 . 2 . 1 to be reversibly connected to one another, in particular by clamping and / or snapping (not shown in detail).

[0169] The protective element 1.2 can be designed, for example, as a spring plate 1.2.13. The component 2 has a slope 2.8. Conversely, the protective element 1.2 can have a slope 2.8 and the component 2 can be designed as a spring plate 1.2.13 in a partial section (not shown in detail).

[0170] The protective element 1 . 2 is arranged, in particular, fixedly on the tolerance compensating element 1 . 1 on one side and can be detachably connected to the component 2 on the other side.

[0171] For example, the protective element 1.2 has a latching element 1.2.15 or a clamping element at the free end 1.2.14. For example, the latching element 1.2.15 is designed in an S-shaped manner (as shown) or in a hook-shaped manner or the like.

[0172] The ramp 2.8 can be designed in a corresponding manner, in particular for the free end 1.2.14. For example, the ramp 2.8 can have a flatter slope in the connection direction 400 than in the opposite opening direction 402. In this way, the protective element 1.2 can be snapped onto the ramp 2.8 in a reversibly locked manner in the connection direction 400 by means of the latching element 1.2.15 or the clamping element. In order to release the second connection part 100.2.2, an opening force is required that overcomes the steeper slope of the ramp 2.8, which releases the latching element 1.2.15 or the clamping element from the engaged state on the ramp 2.8.

[0173] Additionally, at least one compression rib 100.14 may be provided (at Fig.44 ), so as to achieve a seamless connection of the two components 2, 4. For example, the first compression rib 100.14.1, in particular the arc-shaped compression bridge, can extend in the vertical direction z to compensate for tolerances in the vertical direction z.

[0174] The second compression rib 100.14.2, in particular an arc-shaped compression bridge, can extend in the transverse direction y to compensate for tolerances in the transverse direction y. In this way, the tolerance compensation device 100 is free of play in at least two directions by the protective element 1.2, thereby achieving low-noise support.

[0175] In order to mount the tolerance compensation device 100 on the component 2, a support 100.15 is provided. For example, the support 100.15 is designed as a base. The support 100.15 comprises a guide section 100.15.1, in particular two track-shaped projections or two guide ribs. The component 2 comprises a corresponding counterpart guide section 2.9, in particular a guide groove or undercut, in which the track-shaped projection is slidably supported during the mounting process.

[0176] Fig.46 The installation of the tolerance compensating device 100 on the component 2 is shown.

[0177] In the longitudinal direction x, as indicated by arrow 204, the tolerance compensation device 100 is guided, in particular pushed, into the component 2 until the protective element 1.2, in particular its latching element 1.2.15, overcomes the ramp 2.8 and is locked therein, in particular latched.

[0178] To fix the tolerance compensating device 100 in the longitudinal direction x as indicated by arrow 204, the protective element 1.2 can include a stop 1.2.16, in particular a stop strip or the like. The stop 1.2.16 extends obliquely upward from the protective element 1.2 and can abut against the support 100.15.

[0179] like Fig.44 As shown, compression ribs 100 . 14 (also referred to as compression elements) are designed in the region of guide sections 100 . 15 . 1 and allow for a low-noise assembly and connection of the tolerance compensation device 100 and the component 2 .

[0180] In the support 100.15 a nut element 8 can additionally be integrated. Optionally an internal thread can also be integrated.

[0181] Fig.47The guide section 100.15.1 of the support 100.15 is shown, in particular two rail-shaped side projections. The component 2 comprises a corresponding counter-guide section 2.9, in particular a slot or undercut, in which the rail-shaped projections are slidably supported during the assembly process.

[0182] By means of the second compression ribs 100.14.2, the protective element 1.2 and the tolerance compensation device 100 are fixed without play in the component 2. The guide section 100.15.1 can be designed as a hollow profile (as shown) or as a solid profile.

[0183] The nut element 8 is realized centrally in the protective element 1 . 2 .

[0184] In addition, if Fig.47 and 48 As shown, the protective element 1.2 can have a beveled free end 1.2.17 which, in the final installed position, rests against the counter-stop 2.10.

[0185] Fig.49 It is shown that a gap-free state between the protective element 1 . 2 and the component 2 is achieved by means of the second compression rib 100 . 14 . 2 .

[0186] Fig.50 and 52 Two different cross-sectional views of the tolerance compensation device 100 and the component 2 in the assembled state are shown, wherein the protection element 1.2 and the ramp 2.8 overlap and engage one above the other ( Fig.50 ) and front and rear overlap joints ( Fig.52 ).

[0187] Fig.51 and 53 Compression ribs 100.14 are shown, in particular a first compression rib 100.14.1 for compensating for component tolerances in the vertical direction z and a second compression rib 100.14.2 for compensating for component tolerances in the transverse direction y.

[0188] Fig.54 The final assembly state of the tolerance compensation device 100 pre-installed on the component 2 is shown, wherein Fig.55 As shown, the protection element 1.2 is mounted on another component 4, and the axial tolerance 201 is compensated by the compensation element 1.1.3. Fig.55 As shown, by screwing the connecting element 6 into the nut element 8 and tightening it as indicated by the arrow 206 , tolerances between the components 2 and 4 can be compensated for by means of the axially displaceable compensating element 1 . 1 . 3 .

[0189] Fig.56The protective function of the protective element 1 . 2 is shown in the form of an action sequence, in particular the actions that the protective element 1 . 2 may perform as indicated by arrow 210 when a user impacts a component 2 or 4 as indicated by arrow 208 .

[0190] If a pedestrian or other object collides with one of the components 2 or 4, as indicated by arrow 208, the collision energy thus applied to the components 2, 4 can be reduced, for which purpose the tolerance compensation device 100 (in particular the protective element 1.2) is released from the engagement on the ramp 2.8 and can be moved in the longitudinal direction x, as indicated by arrow 210, in the collision direction or in the opposite direction of the collision direction. By reducing the collision energy, pedestrian protection is achieved in a simple manner and personal injuries are minimized.

[0191] Figures 57 to 58 Another connection structure 300 for connecting at least two components 2, 4 is schematically shown by cross-sectional and perspective views, which has a protective element 1.2 with a separation point 100.1 that can be reversibly loosened and a connecting unit 300.1, which includes a compensation element 1.1.3 designed as a compression limiter and an integrated basic element 1.1.1, which is designed as an internal thread 4.2 integrated in the second component 4, in particular, is designed as an internal thread section 4.2.1 of the second component 4.

[0192] For example, the compensating element 1.1.3 has two groups of external thread segments 1.1.31 extending parallel to each other on its outer circumferential direction.

[0193] The compensating element 1.1.3 has two hollow cylindrical halves 1.1.32 that can move axially relative to each other. In this way, the compensating element 1.1.3 is designed as an axial compression limiter. On each hollow cylindrical half 1.1.32 of the compensating element 1.1.3, a set of external thread segments 1.1.31 is designed. The external thread segments 1.1.31 are designed to form multiple external thread segments of the compensating element 1.1.3. Among them, the pitch of the external thread segment 1.1.31 of the compensating element 1.1.3 can match the pitch of the internal thread 4.2 integrated on the inner wall of the second component 4 and having the internal thread segment 4.2.1. For example, the external thread segment 1.1.31 and the internal thread 4.2 form a large pitch thread, so that the threaded engagement of the compensating element 1.1.3 with the second component 4 has no self-locking function and may have a thread gap.

[0194] The protective element 100.2 is designed, for example, as a spring plate 1.2.13, which has a latching element 1.2.15 designed as a reversibly releasable separation point 100.1 at a free end 1.2.14. The latching element 1.2.15 forms a second connection point 100.2.2 of the protective element 100.2 connected to the first component 2. The first connection point 100.2.1 of the protective element 100.2 is designed to be fixedly connected to the second component 4, wherein the base element 1.1.1 is integrated as an internal thread 4.2.

[0195] Figures 59 to 60 Another connection structure 300 for connecting two components 2 and 4 is schematically shown by cross-sectional and perspective views, which has a protective element 1.2 with a reversibly loosen separation point 100.1 and a connecting unit 300.1, which includes a compensation element 1.1.3 with an integrated nut element 1.1.33 and a basic element 1.1.1 including an internal thread 4.2, which in turn forms the internal thread 4.2 of the second component 4.

[0196] Fig.59 and 60 The connection structure 300 shown is Fig.57 and 58 The connection 300 shown differs in that the compensating element 1.1.3 has an integrated nut element 1.1.33. In addition, a washer 1.1.34 can be arranged on the outwardly facing end face of the outer compensating element 1.1.3. The compensating element 1.1.3 is formed by two hollow cylindrical halves 1.1.32 which are axially displaceable relative to one another.

[0197] Protection element 100.2 is similar to Fig.57 and 58 Designed as spring plate 1.2.13.

[0198] Figures 60 to 61 Another connection structure 300 for connecting two components 2 and 4 is schematically shown by cross-sectional and perspective views, which has a protective element 100.2 with a reversibly loosen separation point 100.1 as a second connection location 100.2.2 for connecting the first component 2, and a connecting unit 300.1, which includes a simple compensation element 1.1.3 with an integrated internal thread 1.1.35 and a metric external thread 1.1.36 and a basic element 1.1.1 including an internal thread 4.2, which simultaneously forms the second component 4.

[0199] As mentioned above, the connecting element 6 (in Figure 6 ) can be screwed into the compensation element 1.1.3.

[0200] Protection element 100.2 and Fig.57 and 58The spring plate 1.2.13 is designed similarly and has a reversibly detachable separation point 100.1 as the second connection point 100.2.2.

[0201] Fig.63 Another connection structure 300 is schematically shown in a cross-sectional view, which has a protective element 100.2 designed as a spring plate 1.2.13 and having a reversibly loosen separation point 100.1 as a second connection part 100.2.2, and a connection unit 300.1 designed as a screw connection 300.2, which includes a connection element 6 designed as a hollow screw and optionally designed as a compensation element 1.1.3 and a base element 1.1.1 as an internal thread 4.2 of the second component 4.
