Description

Technical Field

[0001] The present disclosure relates to an exterior decoration device. Background Art

[0002] Typically, a vehicle is completed with exterior trim devices positioned and assembled between various panels to enhance the vehicle's exterior design.

[0003] For example, decorative parts and vehicle emblems (or badges) are used as exterior decorative devices. In this case, decorative parts are configured as molded products with a relatively long length and are classified into front decorative parts, trunk decorative parts, side decorative parts, fender decorative parts, etc. according to the location of the decorative attachment part of the vehicle. Vehicle emblems (or badges) are installed on the front panel, hood, trunk panel, trunk door, etc.

[0004] Specifically, each of the decorative piece and the vehicle logo (or emblem) has a mounting clip that is arranged on a surface opposite to the outer surface of the decorative piece, and the mounting clip is adapted and inserted into the panel hole to fix the decorative piece so that the portion between the panels can be decorated with the outer surface of the decorative piece.

[0005] However, in the case where the structure of the decorative member uses the mounting clip applied to the exterior decorative device, the decorative member and the panel are manufactured separately and then assembled between the panels. As a result, a height difference is inevitably formed at the boundary portion where the decorative member and the panel meet.

[0006] For example, when a trim piece is directly assembled with an outer panel using mounting clips, the outer panel is expected to have formability such that the outer panel has a relatively concave portion that corresponds to the shape of the trim piece, and a surface height difference is formed between the shaped portion and the straight surface of the trim piece. As a result, the trim piece cannot be smoothly fitted with the outer panel, which may result in an uneven appearance.

[0007] As another example, a decorative member may be assembled with a double-panel structure including an outer panel and an inner panel so that the decorative member is arranged in the space between the outer panel and the inner panel. However, since the decorative member depends on the dimensional dispersion and assembly dispersion of the inner panel assembled by the mounting clip, it is difficult to manage the height difference of the gap between the decorative member and the outer panel. As a result, the decorative member cannot be smoothly matched with the outer panel, which may result in an uneven appearance.

[0008] Furthermore, with the design trend of future electric vehicles (e.g., eco-friendly vehicles such as electric and hydrogen-electric vehicles), exterior decorative features such as trim and vehicle emblems (or badges) are expected to have smooth surfaces that do not protrude from the panel when assembled. However, existing exterior decorative features are secured to the outer or inner panel using mounting clips. Consequently, structurally, it is difficult to meet the design trend of preventing separately manufactured components from protruding and maintaining the boundary between the two components so that the two components appear to have the same surface. Summary of the Invention

[0013] In one form of the present disclosure, the rotating rod may have an externally threaded shaft formed at an upper side of the circular plate flange, and the externally threaded shaft may be fixed to an internally threaded frame hole in the decorative frame through a threaded portion and define the deviation adjustment structure.

[0014] In one form of the present disclosure, in the deviation adjustment structure, when the rotating rod rotates, the threaded engagement portion enables the decorative frame to move in a direction opposite to the direction of movement of the rotating rod.

[0015] In one form of the present disclosure, the rotating rod may have a latch shaft, which is arranged on the lower side of the circular plate flange and coupled to the tool head of the fastening tool, and the bolt latch formed on the bottom surface of the latch shaft can engage with the stepped latch protrusion formed on the bottom surface of the tool head to limit the excessive torque cut-off structure.

[0016] In one form of the present disclosure, the bolt latch and the stepped latch protrusion may be provided in a circular shape.

[0017] In one form of the present disclosure, the excessive torque cut-off structure can transmit torque when the bolt latch and the stepped latch protrusion are engaged with each other, and the excessive torque cut-off structure can cut off the transmission of torque when the bolt latch and the stepped latch protrusion are disengaged.

[0018] In one form of the present disclosure, the bolt latch may have a free end portion separated from the bottom surface, and the free end portion may be separated from the stepped latch protrusion and define the disengaged state.

[0019] In one form of the present invention, the free end portion may have a wedge-shaped tip portion formed by bending an end portion of the free end portion.

[0020] In one form of the present disclosure, the decoration frame may include: an upper end frame including an upper surface coupled to the decoration exposed member; and a lower end frame configured to be coupled to the height difference adjustment bolt and including an edge portion on which a reaction force hook is provided.

[0024] In one form of the present disclosure, the screw member may be fastened to the central hub of the upper end frame and the central boss of the lower end frame.

[0025] In another form, the present disclosure provides a vehicle comprising: a decorative attachment portion; and an exterior decorative device comprising: a decorative body in which an upper end frame and a lower end frame are assembled by screws, the upper end frame comprising an upper surface coupled to a decorative exposed member comprising an exposed outer surface, the lower end frame comprising an edge portion on which an elastically deformable reaction hook is obliquely provided; and a height difference adjustment bolt arranged below the decorative body, the height difference adjustment bolt comprising a deviation adjustment structure, the deviation adjustment structure being fastened to the decorative body and configured to rotate by a torque applied by engagement between a tightening tool and an excessive torque cutting structure, and being configured to adjust a surface height difference of the decorative exposed member and a hook height difference of the reaction hook by a rotational adjustment length, wherein the transmission of torque is cut off by disengagement of a hook repulsion force of the reaction hook.

[0027] In one form of the present disclosure, dimensional deviations between the outer panel and the inner panel can be absorbed by adjusting the length, and the absorption of the dimensional deviation can eliminate the hook height difference, form a hook fixing force through the contact between the reaction force hook and the outer panel, eliminate the surface height difference, and allow the decorative exposed member and the outer panel to be in a surface alignment state.

[0028] In one form of the present disclosure, the exterior trim device may be used as any one of a front trim, a trunk trim, a side trim, and a fender trim depending on a vehicle application location.

[0029] The deviation management type exterior decoration device applied to a vehicle according to the present disclosure achieves the following operations and effects.

[0030] First, during the assembly process of the garnish or emblem (or badge), manufactured as a separate component, the garnish or emblem (or badge) can be adjusted to absorb dimensional variations by adjusting the tightening length of the height adjustment bolts, thereby managing variations. This reduces surface height differences and gap height differences between the outer panels caused by conventional mounting clamp structures. Second, because the tightening length of the height adjustment bolts is adjusted by rotating the bolts, uneven height differences between the panels can be reduced by simply rotating the bolts after the garnish or emblem (or badge) is assembled with the outer and inner panels. Third, because the height adjustment bolts are designed to absorb excessive torque, the outer panels are protected from damage even if excessive torque is applied during length adjustment due to the operator's tendency. Fourth, because the garnish or emblem (or badge) and the outer panel are matched with components without protrusions, even when the garnish or emblem (or badge) is assembled with multiple panels, no uneven appearance is observed. Fifth, because the panels are prevented from being exposed even when assembling multiple panels, a high-quality, protruding-free appearance can be achieved, thus realizing the concept of a future vehicle with a smooth design.

DETAILED DESCRIPTION

[0038] Reference Figure 1 The vehicle 1 includes an exterior decoration device 1-1. Specifically, the exterior decoration device 1-1 is characterized in that the exterior decoration device 1-1 is a deviation management type exterior decoration device 1-1, which can adjust the height difference by applying a height difference adjustment bolt 50 (see Figure 4 ) to manage the deviation of the outer panel 3 - 1 of the trim attachment portion 3 of the vehicle 1 , thereby achieving a smooth appearance design with no surface height difference between the trim exposed member 10 and the outer panel 3 - 1 .

[0039] Therefore, the deviation management type exterior trim device 1 - 1 is suitable for future vehicle design concepts in which components are expected to fit smoothly with each other and without protrusions.

[0040] In the following, the decorative part of the exterior decorative device 1-1 applied to the decorative attachment portion 3 of the vehicle 1 is described as an example, but the description is provided for the purpose of easily describing the components, structure and operation of the exterior decorative device 1-1, and external accessories such as vehicle logos (or badges) or other objects (which are to be attached or installed on the exterior of the vehicle 1) are of course included within the scope of this disclosure.

[0041] Specifically, the exterior trim device 1 - 1 includes a trim body 1 - 1A and a height difference adjusting bolt 50 .

[0042] For example, the decoration body 1-1A includes a decoration exposed member 10 and a decoration frame 20. The decoration exposed member 10 is a molded product for decorating the decoration attachment portion 3 and has a smooth surface and various shapes. The decoration exposed member 10 is coupled to the decoration frame 20 to define a decoration surface exposed to the outside. The decoration frame 20 includes an upper end frame 30 and a lower end frame 40 provided as separate molded products, and the upper end frame 30 and the lower end frame 40 are screwed together by a screw member 20-1 (see FIG. 1 ) in a state where the insertion edge 31 of the upper end frame 30 and the coupling flange 41 of the lower end frame 40 are fitted to each other. Figure 2 ) coupling.

[0043] Specifically, the lower end frame 40 has a reaction hook 47, which is used during the assembly process of the decoration main body 1-1A and the decoration attachment portion 3 (see FIG. Figure 6) relative to the decoration attachment portion 3. The reaction force hook 47 has tension (i.e., elasticity) so that the reaction force hook 47 is retracted by its tension during insertion and then restored to its original position by its tension after insertion. As a result, after full insertion, the reaction force hook 47 serves to fix the decoration body 1-1A to the decoration attachment portion 3 without withdrawing from the decoration attachment portion 3.

[0044] For example, the height difference adjusting bolts 50 are integrally assembled with the decoration body 1 - 1A and include three height difference adjusting bolts, ie, a set of first, second, and third height difference adjusting bolts 50 - 1 , 50 - 2 , and 50 - 3 in the decoration frame 20 .

[0045] Specifically, the first height difference adjusting bolt 50 - 1 , the second height difference adjusting bolt 50 - 2 , and the third height difference adjusting bolt 50 - 3 have the same screw fastening structure.

[0046] The first height difference adjusting bolt 50-1, the second height difference adjusting bolt 50-2, and the third height difference adjusting bolt 50-3 are arranged to provide uniform fixing force by uniformly distributing the tightening force. The first height difference adjusting bolt 50-1 is located in the center section of the decoration body 1-1A, and the second height difference adjusting bolt 50-2 is located on one side of the decoration body 1-1A (e.g. Figure 1 The third height difference adjusting bolt 50-3 is located on the other side of the decorative body 1-1A (eg Figure 1 to the right of the ).

[0047] at the same time, Figure 2 and Figure 3 Detailed structures of the decoration exposed member 10 , the upper end frame 30 , and the lower end frame 40 , which are components of the decoration body 1 - 1A, are shown.

[0048] Reference Figure 2 , the upper end frame 30 is coupled to the lower end frame 40 in a state in which the decoration exposed member 10 is positioned on the upper surface of the upper end frame 30 , thereby defining a single assembly.

[0049] Specifically, the upper end frame 30 is configured as an upper end frame body manufactured as an injection molded product, and the upper end frame body includes an insertion edge 31 , a center hub 33 , a stepped hook protrusion 35 , and a panel seat surface 37 .

[0050] For example, the insertion edge 31 protrudes from the lower surface of the upper end frame by a predetermined height and is formed at a location where a portion of the upper end frame is recessed inward. A central hub 33 is arranged in the central portion of the upper end frame where the width and length directions intersect, and the central hub 33 protrudes by a predetermined height while having a height difference relative to the panel seating surface 37. A stepped hook protrusion 35 is spaced apart from the insertion edge 31 on the lower surface of the upper end frame and has a stepped cross-sectional structure provided at the end of the upper end frame. The panel seating surface 37 is formed on the upper surface of the upper end frame and has a depth equal to the thickness of the decorative exposed member 10.

[0051] Specifically, the central hub portion 33 protrudes to the same height as the insertion edge 31, and an internal threaded hole is formed at the center of the central hub portion 33, to which the screw member 20-1 is fastened. The stepped hook protrusion 35 has a stepped cross-sectional structure and limits the position of the reaction hook 47 of the lower end frame 40 pushed by the hook elastic deformation (K) (see Figure 6 The panel seat surface 37 is connected to the decoration exposed member 10 by interference fit to fix the decoration exposed member 10 .

[0052] Specifically, the lower end frame 40 is configured as a lower end frame body manufactured as an injection molded product, and includes a coupling flange 41 , a center boss 43 , a hook forming end 44 , a rib 45 , and a reaction force hook 47 .

[0053] For example, the coupling flange 41 protrudes from the upper surface of the upper end frame to a predetermined height. A central boss 43 is provided in the central portion of the lower end frame where the width direction and the length direction intersect each other, and the central boss 43 protrudes to a predetermined height. The hook-forming end 44 is formed by pressing a portion of the coupling flange 41 inward. The rib 45 protrudes to a predetermined height between the coupling flange 41 and the central boss 43. The reaction hook 47 is spaced apart from the hook-forming end 44 at an acute angle and is integrally formed with the hook-forming end 44 while having tension (i.e., elasticity).

[0054] Specifically, the coupling flange 41 is sized so that the insertion edge 31 of the upper end frame 30 is inserted into the space formed within the coupling flange 41. An internally threaded hole is formed in the center of the center boss 43, into which the screw member 20-1 is fastened. The center boss 43 protrudes at the same height as the coupling flange 41 and has an internally threaded hole formed in the center of the center boss 43, into which the screw member 20-1 is fastened. The center boss 43 is adapted to fit a flange seat surface formed at a predetermined depth in the lower surface of the center hub 33 of the upper end frame 30, allowing the internally threaded hole of the center boss 43 to be easily aligned with the internally threaded hole of the center hub 33. The rib 45 enhances the rigidity of the upper end frame.

[0055] In addition, the reaction hook 47 has a panel contact height H higher than the coupling flange 41, and the panel contact height H allows the reaction hook 47 to contact the stepped hook protrusion 35 of the upper end frame 30 when the reaction hook 47 is folded (i.e., elastically deformed), and allows the reaction hook 47 to contact the outer panel 3-1 (see FIG. 2 ) of the decoration attachment portion 3 when the reaction hook 47 is unfolded (i.e., returned to the initial position). Figure 6 ) contact to limit the position of the reaction hook 47.

[0056] Reference Figure 3 , the lower end frame 40 has hook forming ends 44, which are formed on the coupling flange 41 and spaced apart from each other at predetermined intervals, and the number of reaction hooks 47 is equal to the hook forming ends 44. In this case, the hook forming ends 44 generate a contact fixing force by closely contacting with the insertion edge 31 of the upper end frame 30, and a screw fastening force (see FIG. 20 ) with the screw member 20-1. Figure 2 ) together to maintain the assembly state of the upper end frame 30 and the lower end frame 40.

[0057] Specifically, the reaction force hook 47 includes twelve reaction force hooks 47 , that is, a group of first to twelfth hooks 47 a , 47 b , 47 c , 47 d , 47 e , 47 f , 47 g , 47 h , 47 i , 47 j , 47 k , and 47 l .

[0058] For example, assuming that the entire periphery of the coupling flange 41 is divided into a portion, b portion, c portion, and d portion, three hook-forming ends 44 are provided in each of the a portion, b portion, c portion, and d portion.

[0059] Therefore, the first hook 47a, the second hook 47b and the third hook 47c are designated as a group and formed at the hook forming end 44 in part a, the fourth hook 47d, the fifth hook 47e and the sixth hook 47f are designated as a group and formed at the hook forming end 44 in part b, the seventh hook 47g, the eighth hook 47h and the ninth hook 47i are designated as a group and formed at the hook forming end 44 in part c, and the tenth hook 47j, the eleventh hook 47k and the twelfth hook 47l are designated as a group and formed at the hook forming end 44 in part d.

[0060] As described above, the first to twelfth hooks 47a, 47b, 47c, 47d, 47e, 47f, 47g, 47h, 47i, 47j, 47k and 47l are coupled to the outer panel 3-1 (see FIG. 1 ) of the decoration attachment portion 3 in the a portion, b portion, c portion and d portion of the coupling flange 41 in such a manner that three hooks are designated as one group. Figure 6) to uniformly restrict the position of the decoration body 1-1A. In this case, the position restriction state of the first to twelfth hooks 47a, 47b, 47c, 47d, 47e, 47f, 47g, 47h, 47i, 47j, 47k, and 47l transmits a repulsive force to the height difference adjusting bolt 50 when the height difference adjusting bolt 50 rotates.

[0061] Specifically, more than 12 capture hooks 47 may be used for a mounting portion where a stronger position-restricting state is desired, while fewer than 12 capture hooks 47 may be used for a mounting portion where a weaker position-restricting state is desired.

[0062] at the same time, Figure 4 and Figure 5 Detailed configurations of the height difference adjusting bolt 50 and the tightening tool 60 are shown, and the tightening tool has a structure suitable for the height difference adjusting bolt 50. In this case, the height difference adjusting bolt 50 includes a first height difference adjusting bolt 50-1, a second height difference adjusting bolt 50-2, and a third height difference adjusting bolt 50-3, but since the first height difference adjusting bolt 50-1, the second height difference adjusting bolt 50-2, and the third height difference adjusting bolt 50-3 are configured by the same components, the height difference adjusting bolt 50 will be described.

[0063] Reference Figure 4 The height difference adjusting bolt 50 includes a bolt body 51 , and the bolt body 51 has a rotating rod 52 and a circular plate flange 53 .

[0064] For example, the rotating rod 52 has a linear shape of a predetermined length and has an externally threaded shaft 52A formed on one side thereof. The circular plate flange 53 has a circular shape of a predetermined thickness and protrudes from the upper and lower surfaces of the circular plate flange 53 and is arranged at the center thereof.

[0065] Therefore, the bolt body 51 defines a “+”-shaped cross-sectional structure through the rotating rod 52 and the circular plate flange 53 .

[0066] In addition, the height difference adjusting bolt 50 and the decorative frame 20 constitute a deviation adjusting structure 49 , which is defined by a combination of the internal threaded frame hole 49 a of the decorative frame 20 and the external threaded shaft 52A of the height difference adjusting bolt 50 .

[0067] For example, the internal threaded frame holes 49 a include an upper threaded hole 49 - 1 formed in the upper end frame 30 as a component of the decoration frame 20 and a lower threaded hole 49 - 2 formed in the lower end frame 40 as a component of the decoration frame 20 .

[0068] For example, the externally threaded shaft 52A extends from the lower threaded hole 49 - 2 to the upper threaded hole 49 - 1 , and the threaded portion length is shorter than the threaded hole depths of the lower threaded hole 49 - 2 and the upper threaded hole 49 - 1 .

[0069] Therefore, the external threaded shaft 52A extends from the upper end threaded hole 49 - 1 along the rotation direction of the bolt body 51 or retracts into the upper end threaded hole 49 - 1 , so that the height difference adjusting bolt 50 can adjust the threaded fastening length through the deviation adjusting structure 49 .

[0070] Reference Figure 5 The fastening tool 60 applies a rotational force to the height difference adjusting bolt 50 so that the height difference adjusting bolt 50 adjusts the thread fastening length relative to the decoration body 1 - 1A.

[0071] For example, the tightening tool 60 has a tool head 61 formed at one end of a gripping portion serving as a handle, and the tool head 61 is coupled to a latch shaft 52B formed on a relative portion (i.e., an axial portion opposite to the externally threaded shaft 52A) of a rotating rod 52 forming a bolt body 51 of the height difference adjustment bolt 50.

[0072] Therefore, in a state where the decoration main body 1 - 1A and the decoration attachment portion 3 are assembled, the tool head 61 is coupled to the latch shaft 52B of the bolt body 51 , and the fastening tool 60 applies torque to the bolt body 51 , thereby applying rotational force to the bolt body 51 .

[0073] Therefore, the bolt body 51 absorbs dimensional deviation or assembly deviation by applying torque using the tightening tool 60 and adjusting the thread tightening length using the deviation adjusting structure 49, thereby being able to remove the surface height difference or gap height difference of the decorative exposed member 10 when the decorative main body 1-1A is assembled with the decorative attachment portion 3.

[0074] Furthermore, the height difference adjusting bolt 50 and the tightening tool 60 form an excessive torque cutoff structure 70 .

[0075] Specifically, the excessive torque cutoff structure 70 is defined by combining the bolt latch 71 formed on the bolt body 51 of the height difference adjusting bolt 50 and the stepped latch protrusion 73 formed on the tool head 61 of the fastening tool 60 .

[0076] For example, by forming a circular edge on the bottom surface of the latch shaft 52B of the rotating rod 52 of the bolt body 51, dividing the circular edge into edge portions formed at predetermined intervals, and forming a free end portion separated from the bottom surface and having a protruding structure in each edge portion, the bolt latch 71 is formed to have tension (i.e., elasticity) in its structure.

[0077] For example, by forming a circular groove having a size consistent with the circular edge in the bottom surface of the tool head 61, and forming protrusions at predetermined intervals in the circular groove, the end of the free end portion of the bolt latch 71 is inserted into the stepped protrusion space between the protrusions, thereby forming a stepped latch protrusion 73.

[0078] Therefore, when the height difference adjusting bolt 50 receives the hook repulsion force from the reaction force hook 47 in the position limiting state of the reaction force hook 47, the excessive torque cutting structure 70 generates a "biting" contact sound through the hook repulsion force between the end of the free end portion of the bolt latch 71 and the stepped latch protrusion 73, so that the operator can recognize the completion of assembly.

[0079] Specifically, the bolt latch 71 has a wedge-shaped tip portion 71a (see FIG. Figure 7 ), and the wedge-shaped tip portion 71a makes it easy for the stepped latch protrusion 73 to be inserted into the stepped protrusion space between the protrusions.

[0080] at the same time, Figure 6 and Figure 7 The assembly process of an exterior trim device 1-1 in a vehicle 1 is shown. In this case, in the vehicle 1, the exterior trim device 1-1 is used not only in the portion where decorative parts are assembled, but also in the portion where a vehicle emblem (or badge) is assembled, and in the portion where other exterior accessories are assembled. As an example, a configuration will be described in which the exterior trim device 1-1 is assembled using a trim attachment portion 3 in the vehicle 1, and the trim attachment portion 3 includes an outer panel 3-1 and an inner panel 3-2 spaced apart from the outer panel 3-1.

[0081] refer to Figure 6 The exterior trim device 1-1 includes a trim body 1-1A and a height adjustment bolt 50. In this case, the trim body 1-1A is assembled into an upper end frame 30 having a panel seat surface 37 on which the trim exposed member 10 is assembled. The upper end frame 30 is coupled to the lower end frame 40 via a screw member 20-1 that is fixed to the center hub 33 and the center boss 43 via a threaded portion. Furthermore, the height adjustment bolt 50 is assembled by fixing the externally threaded shaft 52A of the rotating rod 52 of the bolt body 51 via a threaded portion to the internally threaded frame holes 49a of the upper end frame 30 and the lower end frame 40.

[0082] First, the decoration body 1 - 1A is placed in a decoration body installation space formed by pressing the inner panel 3 - 2 relative to the opening portion of the outer panel 3 - 1 .

[0083] Then, in the process of pushing and inserting the decorative body 1-1A into the decorative body installation space, the reaction hook 47 of the lower end frame 40 contacts the outer panel 3-1 and the reaction hook is continuously pushed through the elastic deformation K of the hook generated by tension (i.e., elasticity), and the reaction hook 47 is pushed toward the stepped hook protrusion 35 of the upper end frame 30, so that the decorative body 1-1A is completely inserted into the decorative body installation space.

[0084] Then, after the decoration body 1 - 1A is completely inserted, the reaction hook 47 is separated from the outer panel 3 - 1 and returns to the initial state.

[0085] Then, after the decoration body 1 - 1A is completely inserted, the reaction hook 47 is separated from the outer panel 3 - 1 and returns to the initial state.

[0086] For example, when the reaction force hook 47 does not contact the bottom surface of the outer panel 3-1 or contacts only the bottom surface of the outer panel 3-1, a hook height difference W is formed, so that the reaction force hook 47 may not form a sufficient contact force with the outer panel 3-1 to generate the hook fixing force F (see FIG. Figure 7 ). Further, a surface height difference X is formed due to the protrusion of the decoration exposed member 10, and the surface height difference X causes the outer panel 3-1 to not have a smooth surface.

[0087] Therefore, the height difference adjusting bolt 50 is coupled to the fastening tool 60 , and the tool head 61 of the fastening tool 60 applies torque to the latch shaft 52B of the rotating rod 52 of the bolt body 51 , so that the deviation adjustment assembly process is performed by rotating the height difference adjusting bolt 50 .

[0088] Reference Figure 7 , when the height difference adjusting bolt 50 is rotated by the torque from the tightening tool 60 , the deviation adjusting structure 49 and the excessive torque cutting structure 70 operate.

[0089] For example, in the deviation adjustment structure 49, when the rotating rod 52 of the bolt body 51 is rotated by the torque from the tightening tool 60, the rotation of the rotating rod 52 allows the external threaded shaft 52A to extend from the upper end threaded hole 49-1 of the upper end frame 30, and the bolt body 51 moves downward so that the circular plate flange 53 of the bolt body 51 contacts the upper surface of the inner panel 3-2.

[0090] At the same time, the downward movement of the bolt body 51 pushes the decorative body 1-1A upward toward the outer panel 3-1, and the upward movement of the decorative body 1-1A causes the reaction hook 47 to be in close contact with the outer panel 3-1 to enhance the contact state, thereby forming a surface alignment state Z together with the hook fixing force F.

[0091] As described above, during the assembly process of the decorative body 1-1A, the deviation adjustment structure 49 absorbs the dimensional deviation Y of the decorative body 1-1A by adjusting the threaded fastening length relative to the height difference adjustment bolt 50, so that the fixed state of the decorative body 1-1A can be maintained by the hook fixing force F, and a smooth surface can be achieved by removing the surface height difference X with the surface alignment state Z.

[0092] Then, the hook fixing force F causes the hook repulsive force to operate the excessive torque cutoff structure 70 .

[0093] For example, the torque continuously applied to the height difference adjusting bolt 50 by the tightening tool 60 applies a hook repulsion force higher than the hook fixing force F to the reaction force hook 47, and the hook repulsion force operates to allow the wedge-shaped tip portion 71a of the bolt latch 71 formed on the latch shaft 71 of the bolt body 51 to be inserted into the stepped protrusion space between the protrusions of the stepped latch protrusion 73 constituting the tool head 61.

[0094] That is, in a state where the bolt latch 71 and the stepped latch protrusion 73 are in contact with each other via the wedge-shaped tip portion 71 a, the torque from the fastening tool 60 acts as a limiting force for rotating the bolt body 51 until the hook fixing force F is formed. However, after the hook fixing force F is formed, the hook repulsive force generated by the continued application of the torque is transmitted to the bolt body 51.

[0095] Therefore, the hook repulsive force serves to allow the wedge-shaped tip portion 71a of the bolt latch 71 to withdraw from the stepped latch protrusion 73 by the tension (i.e., elasticity) of the bolt latch 71. And with torque transmitted from the tightening tool 60, the separation between the bolt latch 71 and the stepped latch protrusion 73 allows the bolt body 51 to rotate freely.

[0096] As described above, the free rotation of the bolt body 51 against the torque from the fastening tool 60 generates a "snapping" sound, which is a contact noise generated by repeatedly performing contact and separation between the wedge-shaped tip portion 71a of the bolt latch 71 and the stepped latch protrusion 73. The "snapping" sound notifies the operator of the completion of assembly and allows the operator to recognize that the decoration body 1-1A is completely installed, thereby causing the operator to stop rotating the fastening tool 60.

[0097] Therefore, as mentioned above Figure 6 and Figure 7 As described above, the deviation management type exterior decoration device 1-1 allows a decorative part or vehicle emblem (or badge) to be inserted between a plurality of panels to absorb dimensional deviations of surrounding parts, so that the decorative part or vehicle emblem (or badge) can be matched with the surrounding parts to achieve a uniform surface. Specifically, even if an uneven height difference with the surrounding parts occurs during or after assembly, the height difference adjustment bolt 51 (see FIG. Figure 4 ) alleviates excessive torque that may occur depending on the operator's working tendencies, making it possible to provide a high-quality appearance match during assembly without damaging the outer panel.

[0098] As described above, a deviation management type exterior trim device 1-1 applied to a vehicle 1 according to one form of the present disclosure includes: a trim body 1-1A formed by screwing together an upper end frame 30 and a lower end frame 40, the upper end frame 30 having an upper surface coupled to a trim exposed member 10 including an exposed outer surface, and the lower end frame 40 having a reaction force hook 47; and a height difference adjustment bolt 50 configured to adjust the surface height difference X of the trim exposed member 10 and the hook height difference W of the reaction force hook 47 by adjusting the protruding length of the trim body 1-1A and by rotating a deviation adjustment structure 49, and configured to cut off the transmission of torque by disengaging the hook repulsive force of the reaction force hook 47. The rotation of the deviation adjustment structure 49 is caused by the engagement between the fastening tool 60 and the excessive torque cutting structure 70.

[0099] Therefore, when the deviation-management-type exterior trim device 1-1 is assembled with the trim attachment portion 3 of the vehicle 1, the height difference adjustment bolt 50 adjusts the surface height difference X of the trim exposed member 10 having an exposed outer surface and the hook height difference W of the reaction hook 47 by rotating the deviation adjustment structure 49. This rotation is caused by the engagement between the tightening tool 60 and the excessive torque cutoff structure 70. The height difference adjustment bolt 50 is unable to receive the torque caused by the disengagement of the hook repulsive force of the reaction hook 47, so that the adjustment of the tightening length of the height difference adjustment bolt 50 absorbs the dimensional deviation of the inner panel 3-2. As a result, deviation management can be easily performed on the panel. Specifically, the outer panel 3-1 having an exposed outer surface matches the surface of the trim exposed member 10, resulting in a uniform surface with no surface height difference or gap height difference between the panels in the assembled state. As a result, a smooth design appearance can be achieved.
