Description

Technical Field

[0001] The present disclosure relates to a deformation device for a vehicle, and in particular to a deformation device comprising a bumper beam, a deformation member and a contact member, wherein the contact member can be connected to a longitudinal member of the vehicle. Background Art

[0002] Existing deformation devices for vehicles include deformation members arranged between the bumper beam and the longitudinal components of the vehicle. When a collision occurs, the corresponding deformation member can absorb the force acting on the bumper beam by deformation, thereby preventing other components of the vehicle body from being damaged.

[0003] However, existing deformable members often have the following disadvantages: they are usually unable to effectively limit the bending moment acting on the deformable device components; the manufacturing process is complicated; and they are usually formed of different materials and multiple components.

[0004] Document DE 10 202 111 5 455 A1 discloses a frame of an electric vehicle.

[0005] Document DE102016116172A1 discloses a vehicle load introduction system for introducing a load in the opposite direction to the driving direction of the vehicle. Summary of the invention

[0006] An object of the present disclosure is to provide an efficient deformation device for a vehicle.

[0007] The present disclosure is based on the finding that an effective structural connection of the deformation element to the longitudinal component of the vehicle can be achieved by using an integrally formed and materially homogeneous contact element between the deformation element of the deformation device and the longitudinal component of the vehicle, wherein the deformable hinge area of ​​the contact element allows the contact element to deform in a manner that effectively limits the bending moment.

[0008] According to a first aspect, the present disclosure relates to a deformation device for a vehicle, comprising: a bumper beam extending along a transverse axis of the vehicle; and a deformation member extending along a longitudinal axis of the vehicle and connected to the bumper beam by material bonding or force matching, especially by screws, wherein the deformation member has a deformation member end disposed at a side away from the bumper beam and a contact member made of steel or aluminum alloy and disposed at the deformation member end, the contact member being connectable to a longitudinal component of the vehicle extending along the longitudinal axis of the vehicle, wherein the contact member has a first contact member portion and a second contact member portion integrally formed in the contact member. A contact piece part, wherein the first contact piece part is connectable to the longitudinal member of the vehicle, and the second contact piece part is connected to the deformation piece in a material-bonded manner, wherein the contact piece has at least one deformable hinge area connecting the second contact piece part to the first contact piece part, wherein the deformable hinge area is used to absorb a force acting on the deformation piece and causing the deformation piece to be displaced in the event of a collision, wherein the force is at least partially absorbed by deforming the deformable hinge area, thereby causing the second contact piece part to be displaced and rotated relative to the first contact piece part.

[0009] In this way, the technical advantage achieved is that in the deformation device, a connection structure is provided between the deformation element and the vehicle longitudinal member, which connection structure can be deformed in an advantageous manner in the event of a vehicle collision.

[0010] The contact piece arranged at the end of the deformable piece is made of steel or aluminum alloy, so it can be mass-produced with high cost performance. In addition, the contact piece has an integrally formed design and a uniform material.

[0011] Furthermore, the contact element has the advantage that the force that can be transmitted can be adjusted by adjusting the area of ​​the contact element and the hardness or tensile strength of the two contact element parts of the contact element. In addition, the internal friction of the deformable hinge area can achieve a limit to the bending moment.

[0012] The shape, size and strength of the first and second contact parts may vary depending on the structural component to be secured and the forces to be transmitted.

[0013] Furthermore, the shape, size, strength, position and number of the deformable hinge area and / or the size, position and number of the connecting structures may vary depending on the forces to be transmitted and the bending moments to be limited.

[0014] The deformable hinge area is particularly used to displace the deformable element in the event of a collision, at least in part by causing the force acting on the deformable element to rotate the second contact element part relative to the first contact element part around a vehicle vertical axis extending through the deformable hinge area, wherein the vehicle vertical axis not only crosses the vehicle transverse axis but also crosses the vehicle longitudinal axis.

[0015] Furthermore, in the event of a collision, forces acting along the vehicle longitudinal axis on the deformation element and displacing the deformation element may at least partially displace the second contact element part relative to the first contact element part, in particular as part of a superimposed rotational and translational movement.

[0016] According to one embodiment, the first contact part and the second contact part are integrally formed in the contact from a uniform material.

[0017] In this way, the technical advantage is achieved that an advantageous production of the contact element can be achieved.

[0018] According to one embodiment, the first contact part is formed as a first contact plate, and the second contact part is formed as a second contact plate connected to the first contact plate via the deformable hinge element, and the first contact plate and the second contact plate are aligned with each other in a gap-free and / or substantially plane-parallel manner in the normal state of the deformation device.

[0019] In the scope of the present invention, the expression "substantially plane-parallel" also includes the case where there is a deviation from mathematical parallelism within the range of -5 to +5 degrees.

[0020] In this way, the technical advantage achieved is that, by forming the two contact parts as contact plates, in particular contact plates aligned with each other in a gap-free and / or plane-parallel manner, a particularly stable design of the contact can be achieved in the normal state of the contact, i.e. in the undeformed state. In addition, the vehicle longitudinal component and the deformation element and their connection structure can be based on the existing technology or be improved on the basis of the existing technology without special treatment.

[0021] According to one embodiment, the deformable hinge area is formed by the reshaped edge and / or arc portion of the second contact part, especially the second contact plate, and the second contact part is integrally formed with the first contact part, especially the edge of the first contact plate.

[0022] In this way, a technical advantage is achieved in that the corresponding reshaped edge and / or arcuate portion of the second contact element portion introduces a local structural weakening in the deformable hinge area to enable deformation and displacement in a collision situation.

[0023] According to one embodiment, in the installed state of the vehicle, the deformable hinge area is arranged on the inner side of the contact member away from the outer side of the vehicle.

[0024] In this way, the technical advantage achieved is that in the event of a collision during the center column test, it is ensured that the contact element deforms inwardly.

[0025] According to one embodiment, the second contact piece part has a preset breaking point area, wherein the deformable hinge area is used to break the connection of the preset breaking point area in a preset manner by deforming the deformable hinge area and thereby causing the second contact piece part to displace and rotate relative to the first contact piece part when a collision occurs, especially in a center column test.

[0026] Thus, the technical advantage achieved is that the corresponding preset breaking point area of ​​the second contact part enables the breaking of the second contact part to be limited to a local position, so that the second contact part rotates relative to the first contact part with a preset force. Thus, the load at the connection point between the deformation member and the contact member and between the contact member and the longitudinal member of the vehicle is reduced, and deformation or tearing that is not in the preset manner is reliably prevented.

[0027] The preset breaking point region is particularly arranged on the outer side of the contact member facing the outer side of the vehicle, wherein the preset breaking point region and the deformable hinge region are particularly arranged on opposite sides of the contact member.

[0028] The preset breaking point area particularly includes an area of ​​the second contact part, the hardness of which is lower than the hardness of the remaining area of ​​the second contact part, and the preset breaking point area is particularly configured as a softened or incompletely hardened flexible strip area.

[0029] Alternatively, the predetermined breaking point region has an opening, or a wall thickness is smaller than a wall thickness of the remaining portion of the contact member.

[0030] According to one embodiment, the second contact part is connected to the first contact part via a detachable connection structure, wherein the deformable hinge area is used to separate the detachable connection structure in the event of a collision by deforming the deformable hinge area and thereby causing the second contact part to displace and rotate relative to the first contact part.

[0031] In this way, a technical advantage is achieved in that the separable connection structure ensures that the second contact part can be effectively displaced and effectively rotated relative to the first contact part.

[0032] According to one embodiment, the separable connection structure is disposed on an outer side of the contact member facing the outer side of the vehicle, and the separable connection structure and the deformable hinge area are disposed on opposite sides of the contact member.

[0033] In this way, the technical advantage achieved is that, in the event of a collision, it is ensured that the contact piece is deformed in a predetermined direction.

[0034] According to one embodiment, the separable connection comprises a separable form-fitting and / or force-fitting connection between the first and second contact parts.

[0035] According to one embodiment, the separable shape-fit and / or force-fit connection structure includes a bending point arranged at the edge of the first and / or second contact part, which is connected to the second or first contact part, and / or the separable shape-fit and / or force-fit connection structure includes a protrusion arranged on the first and / or second contact part, which is accommodated in an accommodating groove arranged on the second and / or first contact part.

[0036] Thus, the technical advantage achieved is that the above-mentioned design of the corresponding detachable connection structure enables the second contact part to be displaced in a favorable manner and rotated in a favorable manner relative to the first contact part. Thus, the load at the connection point between the deformation member and the contact member and between the contact member and the longitudinal member of the vehicle is further reduced, and deformation or tearing in an unpredictable manner is reliably prevented.

[0037] According to one embodiment, the detachable connection structure is a protrusion formed at the edge of the first contact part and / or the edge of the second contact part, and the protrusion engages with the corresponding other contact part along its edge to form a shape-fitting or force-fitting connection between the first and second contact parts.

[0038] In this way, the technical advantage achieved is that an advantageous detachable connection structure can be formed by the tab.

[0039] According to one embodiment, the deformable hinge area is used to cause the second contact member part to effectively displace and rotate relative to the first contact member part when the force causing the deformation member to displace exceeds a preset force threshold in the event of a collision, especially a central column collision, wherein the preset force threshold is particularly smaller than the maximum resistance of the connecting structure between the deformation member and the contact member.

[0040] In this way, the technical advantage achieved is that unnecessary deformation of the contact piece is not triggered when extremely small forces act on the contact piece, or in other collision situations, or in other collision tests such as the "RCAR (Repair Research Council of Automobiles) Structure" or "RCAR Bumper" test.

[0041] According to one embodiment, the deformable hinge area is used to cause a restoring bending moment opposite to the deformation direction of the deformable hinge area when a collision occurs, so as to limit the displacement of the second contact piece portion relative to the first contact piece portion and dissipate the collision energy at the same time.

[0042] In this way, the technical advantage achieved is that, even if a large force is generated during a collision, the second contact piece portion cannot be infinitely displaced relative to the first contact piece portion, thereby increasing safety during a collision.

[0043] According to one embodiment, the deformable hinge area is used to rotate the second contact piece part relative to the first contact piece part around the vehicle vertical axis that passes through the longitudinal axis of the vehicle and the transverse axis of the vehicle when a collision occurs and the force acting on the deformable piece causes the deformable piece to be displaced, and / or the deformable hinge area is used to translate the second contact piece part relative to the first contact piece part along the longitudinal axis of the vehicle when the force acting on the deformable piece causes the deformable piece to be displaced.

[0044] In this way, the technical advantage achieved is that the force can be effectively absorbed by the directional rotation of the second contact part relative to the first contact part.

[0045] According to one embodiment, openings are respectively formed in the first contact part (especially the first contact plate) and the second contact part (especially the second contact plate), and the openings are arranged to be aligned with each other in the normal state of the deformation device.

[0046] In this way, the technical advantage achieved is that, by respectively providing corresponding openings in the contact pieces, the weight of the contact pieces can be reduced, and at the same time, the mechanical properties of the contact pieces will not be negatively affected.

[0047] According to one embodiment, a plurality of protrusions and / or recesses and / or circumferential edge changes are formed on the first contact element part (especially the first contact element plate) and / or the second contact element part (especially the second contact element plate).

[0048] The technical advantage achieved in this way is that by introducing elevations and / or depressions, the structural properties of the contact element can be optimized locally and the bending stiffness can be increased in particular outside the hinge region and any detachable connection.

[0049] According to one embodiment, the first contact part has a plurality of openings, each of which can be penetrated by a fastener, in particular a fastening screw, for fixing the first contact part to the vehicle longitudinal component, in particular to another contact of the vehicle longitudinal component, in particular another contact plate.

[0050] In this way, the technical advantage is achieved in that an effective connection to the vehicle longitudinal member is ensured.

[0051] According to one embodiment, the contact piece is formed as a sheet metal piece, wherein the hinge region is formed by bending, or the contact piece is produced by extruding an extruded profile including the hinge region, in particular from an aluminum alloy.

[0052] In this way, the technical advantage achieved is that it is easy to manufacture.

[0053] According to one embodiment, the deformable hinge area, in particular together with the predetermined breaking point area, is formed as a non-thermally hardened or thermally softened area of ​​the contact piece.

[0054] In this way, the technical advantage is achieved that a structural weakening can be introduced in a favorable manner in the corresponding region.

[0055] According to one embodiment, in addition to the deformable hinge region and in particular also in addition to the predetermined breaking point region, the first contact element part and the second contact element part are formed as thermally hardened or thermally softened regions of the contact element.

[0056] In this way, the technical advantage is achieved that structural stability can be achieved in other regions of the contact element.

[0057] According to one embodiment, the first contact part, in particular the first contact plate, and the second contact part, in particular the second contact plate, are at least partially connected to each other via at least one contact point, in particular connected to each other in a frictionally and / or materially connected manner.

[0058] In this way, the technical advantage is achieved that a structurally stable connection can be achieved between the first and second contact parts.

[0059] According to one embodiment, the deformable hinge area is used to separate the contact between the first contact part and the second contact part due to the displacement of the second contact part relative to the first contact part when the force causing the deformation part to displace is greater than the connecting force provided by the contact.

[0060] In this way, a technical advantage is achieved in that effective restrictions can be introduced.

[0061] According to one embodiment, a plurality of protrusions and / or depressions are formed in the deformable hinge area.

[0062] In this way, the technical advantage achieved is that the deformation capacity of the deformable hinge area can be adjusted in an advantageous manner.

[0103] Figure 1 The present invention is a schematic diagram of a deformation device for a vehicle according to an embodiment.

[0104] As shown in the figure, Figure 1 The deformation device 100 shown has components which are correspondingly deformed in the event of a collision. Figure 1 The dotted lines in the figure represent the original states of the components of the deformation device 100.

[0105] The deformation device 100 includes a bumper beam 101, which, in its original state, is slightly bent away from the vehicle and further deformed along the same direction as the bumper beam. Figure 1 The vehicle transverse axis 103 extends in the Y direction.

[0106] The deformation device 100 further comprises a deformation member 105, which in its original state extends along the longitudinal axis 107 of the vehicle and is connected to the bumper beam 101 by material bonding or force fit, in particular by screws. The longitudinal axis 107 of the vehicle corresponds to Figure 1 The X direction in .

[0107] The deformation element 105 can be connected to a vehicle longitudinal component 109 which extends along a vehicle longitudinal axis 107 .

[0108] from Figure 1 As can be seen in FIG. 1 , the deformation device 100 comprises two deformation members 105 connected to opposite ends of the bumper beam 101 , wherein each of the two deformation members 105 can be connected to a longitudinal member 109 of the vehicle to achieve a symmetrical stabilizing effect.

[0109] from Figure 1 It can also be seen that a deformation member end 111 is provided on the side of the deformation member 105 away from the bumper beam 101. The deformation member 105 has a contact member 113 made of steel or aluminum alloy, which is provided on the deformation member end 111 and can be connected to the vehicle longitudinal member 109.

[0110] from Figure 1 It can be seen in FIG. 1 that the contact element 113 can be deformed in the event of a collision, in particular in a manner similar to a hinge, so that the corresponding deformation element 105 can be displaced and rotated relative to the vehicle longitudinal component 109 .

[0111] like Figure 1As shown in the diagrammatic representation of the obstacle 115 , the impact of the vehicle on the obstacle 115 , or the contact of the obstacle 115 with the bumper beam 101 , causes the bumper beam 101 to be bent along the longitudinal axis 107 of the vehicle, thereby causing the deformation member 105 to be displaced end-side along the transverse axis 103 of the vehicle.

[0112] In this way, a bending moment will be generated, but if Figure 1 As shown, this bending moment does not lead to deformation of the corresponding vehicle longitudinal member 109 , but rather leads to deformation of the contact piece 113 , thereby achieving effective limitation of the bending moment acting on the corresponding vehicle longitudinal member 109 .

[0113] Hereinafter, the deformable contact member 113 is further described and explained in detail.

[0114] Figure 2A and Figure 2B In one embodiment Figure 1 Schematic diagram of the contact parts of the deformation device.

[0115] In order to better express Figure 2A and Figure 2B The middle contact 113 is relative to Figure 1 The orientation of the deformation device 100 is shown in FIG. Figure 1 , Figure 2A and Figure 2B The X, Y and Z directions are shown in FIG.

[0116] The important point is that Figure 1 compared to, Figure 2A and Figure 2B , the contact member 113 is shown in its undeformed state, ie, its original state before the collision.

[0117] from Figure 2A and Figure 2B As can be seen in FIG. 1 , the contact 113 has a first contact portion 117 (or first contact plate) and a second contact portion 119 (or second contact plate) integrally formed in the contact 113 .

[0118] exist Figure 2A and Figure 2B In the illustrated embodiment, the first and second contact plates are aligned with each other in a plane-parallel manner.

[0119] The first contact portion 117 may be connected to Figure 2A and Figure 2B The vehicle longitudinal member 109 is not shown in the figure. The second contact part 119 is connected to the Figure 2A and Figure 2B The deformation piece 105 (not shown) is materially connected thereto, in particular welded thereto.

[0120] like Figure 2A and Figure 2B As shown, the first contact part 117 has a plurality of openings 121, and a fastener, in particular a fastening screw, can be inserted into each opening 121 to fix the first contact part 117 to the vehicle longitudinal member 109, in particular to the Figure 2A and Figure 2B On another contact element of the vehicle longitudinal component 109 (not shown), in particular on another contact element plate.

[0121] The second contact portion 119 and the deformable member 105 are connected by material bonding or welding.

[0122] from Figure 2A and Figure 2B As can be seen in the drawings, each contact 113 has a deformable hinge area 123 connecting the corresponding second contact part 119 to the corresponding first contact part 117 .

[0123] The deformable hinge area 123 is used to absorb the force acting on the deformable member 105 and causing the deformable member 105 to displace when a collision occurs. The force is at least partially absorbed by the deformable hinge area 123 (to Figure 1 The second contact part 119 is deformed in a similar manner as shown in the figure and the second contact part 119 is displaced and rotated relative to the first contact part 117 ( Figure 2A and Figure 2B The deformable member 105 is displaced by means of a method not shown in the figure.

[0124] from Figure 2A and Figure 2B It can be seen in FIG. 1 that the deformable hinge area 123 is formed in particular by a reshaped edge of the second contact element part 119 , which is formed integrally with an edge of the first contact element part 117 .

[0125] Alternatively, the deformable hinge area 123 may also be formed by an arc portion of the second contact element portion 119 .

[0126] The deformable hinge area 123 is disposed on the inner side 125 of the contact member 113, and the inner side 125 is the side away from the outer side of the vehicle. Figure 1 The method shown is to rotate and unfold on the inside.

[0127] The second contact part 119 is particularly Figure 2A and Figure 2BThe detachable connecting structure 127, which is only schematically shown in the figure, is connected to the first contact piece portion 117, wherein the deformable hinge area 123 is used to separate the detachable connecting structure when a collision occurs and the deformation of the deformable hinge area 123 reaches a preset force, thereby causing the second contact piece portion 119 to be displaced relative to the first contact piece portion 117.

[0128] Each detachable connection structure 127 may in particular further include a corresponding preset breaking point area 129 of the second contact piece part 119, wherein the deformable hinge area 123 is used to break the connection of the preset breaking point area 129 when a collision occurs and the deformation of the deformable hinge area 123 exceeds a preset force, thereby causing the second contact piece part 119 to displace and rotate relative to the first contact piece part 117.

[0129] The detachable connection structure 127 or the preset breaking point area 129 is arranged on the outer side 131 of the contact member 113, and the outer side 131 is the side facing the outer side of the vehicle, wherein the detachable connection structure 127 or the preset breaking point area 129 and the deformable hinge area 123 are arranged on opposite sides of the contact member 113. In this way, the contact member 113 can be Figure 1 Rotate and unfold in the manner shown.

[0130] The separable connection 127 comprises in particular a separable form-fitting and / or force-fitting connection between the first and second contact parts 117 , 119 , wherein the separable material-fitting connection comprises in particular a spot weld between the first and second contact parts 117 , 119 .

[0131] The deformable hinge area 123 is particularly used to effectively displace the second contact member portion 119 relative to the first contact member portion 117 when a collision occurs, especially a collision of the central column, and the force causing the deformation member 105 to be displaced exceeds a preset force threshold, wherein the preset force threshold is particularly less than the maximum resistance of the connection structure between the deformation member 105 and the contact member 113. This displacement can greatly reduce the load on the connection structure and prevent the contact member from tearing or deforming in an unpredictable manner.

[0132] The deformable hinge area 123 is used in particular to move the second contact element portion 119 relative to the first contact element portion 117 about a vehicle vertical axis 133 (corresponding to the vertical axis 133) which is transverse to the vehicle longitudinal axis 107 and to the vehicle transverse axis 103 when a collision occurs and a force acts on the deformable element 105 so that the deformable element 105 is displaced. Figure 1 The deformable hinge area 123 is used to translate the second contact member portion 119 relative to the first contact member portion 117 along the longitudinal axis 107 of the vehicle when a force acts on the deformable member 105 to cause the deformable member 105 to displace.

[0133] from Figure 2A and Figure 2B It can also be seen in the figure that openings 135 are formed in both the first contact part 117 and the second contact part 119 , wherein the openings 135 are arranged to be aligned with each other in the normal state of the deformation device 100 .

[0134] A plurality of protrusions 137 and / or recesses may be formed on the first and / or second contact portions 117 , 119 .

[0135] Figure 3 In one embodiment, a deformable member Figure 2B Schematic diagram of contacts.

[0136] from Figure 3 As can be seen from the figure, the deformable member 105 is firmly connected to the second contact member portion 119 of the contact member 113 through the deformable member end 111 (wherein only the corresponding welding connection structure is schematically shown), thereby achieving an effective anti-collision connection between the contact member 113 and the deformable member 105 with a small force. Figure 3 It can be seen that the shape of the edge of the opening 135 allows the two to support each other along the Y direction and the Z direction, so that the first contact plate and the second contact plate are hooked on the deformable part when an oblique load occurs, especially in the "RCAR (Automotive Repair Research Council) Structure" or "RCAR Bumper" test.

[0137] Regarding the function of the deformable hinge area 123 , please refer to the above description.

[0138] Figure 4 It is a schematic diagram of a deformation device in another embodiment.

[0139] Figure 4 The figure shows the normal state of the deformation device.

[0140] like Figure 4 As shown, the bumper beam 101 is connected to the deformation member 105 of the deformation device 100, wherein the deformation member end 111 of the deformation member 105 is connected to the second contact member portion 119 of the contact member 113. Figure 4 As shown, the first contact part 117 and the second contact part 119 of the contact 113 are integrally formed, wherein the first contact part 117 is connected to the corresponding vehicle longitudinal component 109, in particular to another contact 139 of the vehicle longitudinal component 109, in particular to another contact plate.

[0141] exist Figure 4 In FIG. 1 , the deformable hinge region 123 provided on the inner side 125 of the contact member 113 is not visible, while the separable connection structure 127 provided on the outer side 131 is shown. Figure 4 In the illustrated embodiment, the detachable connection structure 127 includes a protrusion 141 provided on the second contact portion 119 , and the protrusion 141 is received in a receiving groove 143 provided on the first contact portion 117 .

[0143] Figure 5A and Figure 5B Shown is a cross-sectional view of each contact 113 , which includes a first contact portion 117 and a second contact portion 119 , wherein the second contact portion 119 is connected to the first contact portion 117 via a deformable hinge area 123 .

[0144] Figure 5A The first contact part 117, the second contact part 119 and the deformable hinge area 123 are shown as one-piece, especially as an extruded part. A preset breaking point in the form of a weld 145 is formed on the side of the first contact part 117 facing the hinge area. In this way, the contact parts 117 and 119 are kept gapless and / or parallel to each other within a preset force threshold range, especially in the tow hook extraction test. After extrusion molding, the final shape of the contact 113 is achieved by slight bending and / or compression molding to ensure the above-mentioned parallel and / or gapless state. In addition, this final shape is also ensured by the weld 145.

[0145] Figure 5B The first contact part 117 and the deformable hinge area 123 are integrally formed, especially as a first extruded component, and the second contact part 119 is formed as a separate integral component, especially as a second extruded component. Subsequently, one end of the second contact part 119 is welded to the first contact part 117, and the other end is welded to the deformable hinge area 123 to finally form the contact 113. Figure 5B The contact element 113 shown consists of two separate parts, so that, in particular compared to a production method with a sheet metal semi-finished product as starting material, the advantage is that no reshaping of the deformable hinge region 123 is required during the production of the contact element 113 .

[0147] For a detailed description of the contact element 113 , please refer to the detailed description related to FIG. 2 above. Figure 6The contact element 113 shown has a first contact element portion 117 , a second contact element portion 119 and a deformable hinge region 123 connecting the two portions 117 , 119 .

[0148] Figure 6 The difference between the contact 113 shown in FIG. 2 and the contact 113 is that the second contact portion 119 is not limited to the middle portion, but extends to the edge 147 of the first contact portion 117 away from the deformable hinge area 123. In addition, the end of the second contact portion 119 extends to the upper edge 149 and the lower edge 151 of the first contact portion 117.

[0149] In addition, from Figure 6 As can be seen, two other openings 153 are provided at the end of the second contact portion 119, and the two openings 153 are respectively aligned with the openings 121 on the first contact portion 117, so that the corresponding fastening screws for fixing to the vehicle body can pass through the two corresponding openings 121 on the first contact portion 117 and the two other openings 153 on the second contact portion 119 aligned therewith.

[0150] In the event of a collision, when the deformable hinge area 123 bends, the connection between the end of the second contact part 119 and the first contact part 117 will be tightened by the fastening screw ( Figure 6 The corresponding preset breaking point 155 is at Figure 6 It is schematically shown in FIG.
