[0002] Conventional vehicle body assembly construction maintains proper dimensional tolerances of an automobile body and its components when they are assembled together.

[0003] However, after a large number of bolts welded to a bracket that serves as the inner plate of the vehicle body are inserted into fastening holes of the parts, a large number of nuts are fastened to the bolts with a tool.

[0004] Therefore, the worker must hold the part in one hand, temporarily fasten a number of nuts to the bolts with the other hand, and then use the other hand to hold the tool and perform the finish fastening, which increases the number of work steps and is inconvenient for the worker.

[0005] Also, a separate process of welding a large number of bolts to the bracket must be added.

[0006] Furthermore, manufacturing the brackets is difficult, and a large number of brackets must be fixed one by one to the exterior panels of the vehicle body. [Prior art documents] [Patent documents]

[0052] The screw bushing part 100 includes a screw cover part 110. The screw cover part 110 is installed on the mounting part 7. The screw cover part 110 improves the assembling of the fastening module 10 to the mounting part 7.

[0053] The screw cover part 110 includes a hollow cover 120. An inner screw 121 is formed on the inner peripheral surface of the hollow cover 120.

[0054] The screw cover portion 110 includes a detachment portion 130. The detachment portion 130 allows the screw cover 120 to be attached to and detached from the mounting portion 7.

[0055] 7, the detachable part 130 includes a first detachable part 131. The first detachable part 131 is formed in the mounting part 7.

[0056] The first detachable portion 131 includes a first front hook inner protrusion 132. The first front hook inner protrusions 132 are formed on the left and right sides of the front side of the mounting portion 7 so as to protrude toward the center.

[0057] The first detachable portion 131 includes a first rear inner protrusion 133. The first rear inner protrusion 133 is formed in a diagonal direction on the rear side of the mounting portion 7. The first rear inner protrusions 133 are arranged on the top and bottom of the left and right sides when viewed from the front or rear.

[0058] 5 and 6, the detachable portion 130 includes a second detachable portion 134. The second detachable portion 134 is formed in the hollow cover 120.

[0059] The second detachable portion 134 includes a second front hook outer protrusion 135. The second front hook outer protrusions 135 are formed to protrude toward the center on the left and right sides of the front of the hollow cover 120.

[0061] 8 and 9, when the hollow cover 120 is inserted into the mounting part 7 and rotated, the second detachable part 134 is detached from the first detachable part 131.

[0062] In addition, the detachable unit 130 can easily assemble the fastening module 10, which is a previously prepared tolerance module, improving workability, and thereby improving performance such as quality and cost.

[0063] 5 and 6, the screw bushing part 100 includes a screw bush 150. The screw bush 150 has an outer screw 151 formed on its outer circumferential surface. The outer screw 151 of the screw bush 150 is fastened to the inner screw 121 of the hollow cover 120. The screw bush 150 moves linearly relative to the hollow cover 120 by rotating. The inner screw 121 of the hollow cover 120 and the outer screw 151 of the screw bush 150 have a large angle, so that the linear movement is free. The screw bush 150 is fastened and inserted from the front to the rear of the hollow cover 120. The screw bush 150 has a hook protrusion 153 formed on its outer circumferential surface. The hook protrusion 153 is configured as a flange on the front surface of the screw bush 150. The hook protrusion 153 hooks onto the front surface of the hollow cover 120.

[0064] Referring to FIG. 10, the screw bushing 150 includes a unidirectional inclined hook protrusion 152. The unidirectional inclined hook protrusion 152 is formed inside the screw bushing 150. The unidirectional inclined hook protrusions 152 are formed facing each other vertically. The unidirectional inclined hook protrusions 152 allow the bolt portion 200 to move forward and inhibit its backward movement. The unidirectional inclined hook protrusions 152 protrude from the inner peripheral surface of the screw bushing 150, inclining downward as they go forward. The tip of the unidirectional inclined hook protrusion 152 is in a concave arc shape. The concave arc shape is inserted into the outer peripheral surface of the bolt portion 200 to increase the anti-skid force in the rear.

[0065] Such a one-way inclined hook protrusion 152 prevents the bolt part 200 from slipping backward (the bolt thread and the hook protrusion act like a hook, allowing it to move easily forward but get caught backward), maintains the central origin between the screw bushing 150 and the bolt part 200 (ensuring an XZ reference point that is convenient for using tools), prevents play between the screw bushing 150 and the bolt part 200 (improving noise-inducing factors such as impact sounds), and provides a flexible structure that allows tolerance correction by adjusting the XZ directions.

[0066] 5 and 6, the fastening module 10 includes a bolt portion 200. The bolt portion 200 is inserted into the screw bushing 150 from the rear toward the front.

[0067] The bolt part 200 includes a bolt with a washer 200. The bolt part with a washer 200 includes a hexagonal head 210, an external threaded rod 220, and a headed washer 230 formed on the head 210. The head 210 is a tool application part, the external threaded rod 220 is a fastening part of the nut part 300, and the headed washer 230 is a rear end surface pressing part of the screw bush 150. The tip 221 of the external threaded rod 220 is crimped after the fastening module 10 is assembled. The crimping prevents the nut part 300 fastened to the external threaded rod 220 from coming off.

[0068] 5 and 6, the fastening module 10 includes a nut part 300. Referring to Figs. 7 to 10, the nut part 300 is fastened to the male threaded rod 220 protruding forward from the front surface of the hollow cover 120. Thus, the nut part 300 passes from the inside to the outside of the vehicle body part 30, and then tightly couples the inner and outer surfaces of the vehicle body part 30 together with the hollow cover 120 by the pressurized rotation of the bolt part 200.

[0069] The nut part 300 includes a nut with washer 300. The nut with washer 300 includes a nut 310. The nut 310 is fastened to the male threaded rod 220. The nut with washer 300 includes a washer 330. The washer 330 is formed integrally with the nut 310. The washer 330 is polygonal. For example, the washer 330 is square. The square washer 330 easily hooks onto the outer surface of the vehicle body part 30, and prevents the nut 310 from spinning freely.

[0070] A vehicle body assembly according to one embodiment of the present invention includes a vehicle body section 30.

[0071] Referring to FIG. 4, the vehicle body part 30 includes a vehicle body outer plate 40. The vehicle body outer plate 40 is an outer plate having a curved surface.

A guide protrusion 9 is inserted into the outer periphery of the inner horizontal bent piece 45. Referring to FIG. 2, six guide protrusions 9 are formed on the front surface of the housing 5 along the periphery of the grip 4. For example, six guide protrusions 9 are formed, two on the upper side, two on the lower side, and one on each of the left and right sides.

[0072] The body section 30 includes an inner panel 50. The inner panel 50 is disposed apart from the outer panel 40.

[0073] The body panel 50 includes an insert 51 .

[0074] The insertion portion 51 includes an insertion hole 52. The insertion hole 52 is a hole penetrating from front to rear. The insertion hole 52 has a size that allows the square washer 330 to be inserted therein.

[0075] The insertion portion 51 includes a slot 53. The slot 53 is in the shape of a keyway. The slot 53 communicates with one side of the insertion hole 52. The slot 53 is a passage through which the male threaded rod 220 moves. The inner plate 50 around the slot 53 is pressurized by a square washer 330.

[0076] The inner panel 50 includes an anti-rotation piece 54. The anti-rotation piece 54 is a plate formed by pressing the inner panel 50 into a U-shape and then bending it at 90 degrees. The anti-rotation piece 54 is disposed above or below the slot 53. One side of a square washer 330 is adjacent to the underside of the anti-rotation plate 54. The square washer 330 is engaged with the anti-rotation piece 54 to prevent the nut 310 from spinning freely.

[0077] The vehicle body inner panel 50 includes a component insertion hole 55. The front surface of the housing 5 of the component 3 is inserted into the component insertion hole 55. At this time, the mounting portion 7 is disposed inside the vehicle body inner panel 50.

[0078] 11 to 16 are diagrams showing the procedure for assembling the parts shown in FIG. 1 onto a vehicle body.

[0079] 11, the nut portion 300 of the component unit 1 is shown before being inserted into the insertion hole 52 of the body panel 50 inside the vehicle.

[0080] 12, the nut portion 300 of the component unit 1 is shown after being inserted into the insertion hole 52 of the body panel 50 of the vehicle.

[0081] 13, after the nut portion 300 is inserted into the insertion hole 52, the male threaded rod 220 is moved toward the slot 53, and the component 3 is placed in the mounting position.

[0082] 14, after the component 3 is moved and arranged at the mounting position, the housing 5 is pushed forward, so that the six-point guide protrusion 9 is seated on the outer periphery of the inner horizontal bent piece 45, and the grip 4 is accurately arranged in the grip pull-out hole 44, as shown in FIG. 32. In addition, the front surface of the housing 5 is also inserted into the component insertion hole 55, and the guide cover 70 is also inserted while matching with the inner peripheral surface of the inner horizontal bent piece 45.

[0083] 15, when the guide protrusion 9 is seated on the outer periphery of the inner horizontal bent piece 45, the bolt part 200 and the screw bushing 150 move forward due to the force of the tool pressing the bolt part 200, that is, the force of the headed washer 230 pressing the rear end of the screw bushing 150. The screw bushing 150 moves freely with a large screw angle and automatically corrects only the gap with the body panel 50 inside the vehicle.

[0084] 16, if the tool continues to operate with the front surface of the screw bushing 150 abutting against the inner surface of the vehicle body panel 50 and the bolt part 200 rotates to its original position, the nut part 300 moves backward along the male threaded rod 220 without rotating due to the anti-rotation piece 54. The square washer 330 of the nut part 300 is pressurized together with the screw bushing 150 while hanging on the outer surface of the vehicle body panel 50. The screw bushing 150 acts as a stopper between the bolt part 200 and the nut part 300.

[0085] FIG. 17 is an exploded perspective view of a vehicle body assembly structure according to another embodiment of the present invention, as viewed from the rear.

[0086] Referring to Figure 17, the fastening module 10' and the inner panel 50' according to another embodiment are similar to the fastening module 10 and the inner panel 50 according to the first embodiment, but the nut portion 300' of the fastening module 10' and the insertion portion 51' of the inner panel 50' have different shapes and functions from the nut portion of the fastening module 10 and the insertion portion 51 of the inner panel 50.

[0087] FIG. 18 is a perspective view of the fastening module 10' of FIG.

[0088] Referring to FIG. 18, the nut portion 300' of the fastening module 10' includes a shape-changing nut portion 300'.

[0089] The shape-deforming nut portion 300' includes a front ring 310' and a rear ring 320' that are inserted onto the male threaded rod 220. The front ring 310' is configured as a nut with a female thread (not shown) formed on the inner peripheral surface thereof.

[0090] The shape-deforming nut portion 300' includes a plurality of bridges 330'. The plurality of bridges 330' are strip-shaped. The plurality of bridges 330' are connected along the circumference between the front ring 310' and the rear ring 320'. The thickness of the bridges 330' decreases toward the center between the front ring 310' and the rear ring 320'. In other words, the lower surface of the bridges 330' is arch-shaped. Since the center of the bridges 330' is configured to be thin, the front ring 310' can be easily folded while moving toward the rear ring 320'.

[0091] The deformable nut portion 300' includes an anti-slip protrusion 340'. The anti-slip protrusion 340' is hooked onto the outer surface of the vehicle body inner panel 50'. The anti-slip protrusion 340' includes an inclined surface 341'. The inclined surface 341' has a gradient that becomes steeper toward the rear. The inclined surface 341' provides flexibility for the insertion of the insertion portion 51'. The anti-slip protrusion 340' is formed on the outer surface of the rear ring 320' or the rear outer surface of the bridge 330'.

[0092] 17, the vehicle body inner panel 50' includes an insertion portion 51'. The insertion portion 51' includes an insertion hole 52'. The insertion hole 52' has a size for inserting the deformable nut portion 300'. The diameter of the insertion hole 52' is smaller than the outer diameter of the non-slip protrusion 340'. That is, the non-slip protrusion 340' is tightly fitted into the insertion hole 52' by utilizing the inclined surface 341' and elastic deformation.

[0093] 19 to 22 are diagrams showing the procedure for assembling the parts shown in FIG. 17 onto a vehicle body.

[0094] 19, the shape-deformed nut portion 300' of the component unit 1 is shown before being inserted into the insertion hole 52' of the body panel 50' of the vehicle body.

[0095] 20 shows the part unit 1 after the deformable nut portion 300' is inserted into the insertion hole 52' of the inner panel 50'. In other words, when the deformable nut portion 300' is inserted into the insertion hole 52' of the inner panel 50', the rear surface of the anti-slip protrusion 340' is engaged with the outer surface of the inner panel 50' to a degree that does not allow it to slip.

[0096] 32, the front surface of the housing 5 is also inserted into the component insertion hole 55, and the guide cover 70 is also inserted while matching with the inner peripheral surface of the inner horizontal bent piece 45.

[0097] 21, when the guide protrusion 9 is seated on the outer periphery of the inner horizontal bent piece 45, the bolt part 200 and the screw bushing 150 move forward due to the force of the tool pressing the bolt part 200, i.e., the force of the headed washer 230 pressing the rear end of the screw bushing 150. The screw bushing 150 moves freely with a large screw angle, and automatically corrects only the gap with the body panel 50' inside the vehicle body.

[0098] 22, with the front surface of the screw bushing 150 butting against the inner surface of the vehicle body panel 50' and the anti-slip protrusion 340' of the deformable nut part 300' hooking onto the outer surface of the vehicle body panel 50' and unable to rotate due to the anti-rotation piece 54', the tool continues to operate and the bolt part 200 rotates to its original position, and the front ring 310' moves backward along the male threaded rod 220. Then, the center of the bridge 330' is folded and expanded, and while hooked onto the outer surface of the vehicle body panel 50', it is pressurized and coupled with the screw bushing 150. The screw bushing 150 acts as a pawl between the bolt part 200 and the deformable nut part 300'.

[0099] FIG. 23 is an exploded perspective view of a vehicle body assembly structure according to still another embodiment of the present invention, as viewed from the rear.

[0100] Referring to FIG. 23, the fastening module 10'' according to another embodiment is similar to the fastening module 10' according to another embodiment, but the nut portion 300'' of the fastening module 10'' differs in shape and function from the nut portion 300' of the fastening module 10'.

[0101] FIG. 24 is a perspective view of the fastening module 10″ of FIG.

[0102] Referring to FIG. 24, the nut portion 300'' of the fastening module 10'' includes a shape-changing nut portion 300''.

[0103] The deformed nut portion 300 ″ includes a nut 310 ″. The nut 310 ″ is annular. The nut 310 ″ is fastened to the male threaded rod 220 .

[0104] The deformable nut portion 300'' includes a plurality of inclined wings 320''. The inclined wings 320'' protrude from the nut 310'' so as to incline upwards toward the rear. In other words, the inclined wings 320'' are wedge-shaped. The inclined wings 320'' have a shape that can be easily folded and unfolded. The outer diameter of the tip of the inclined wings 320'' is much larger than the inner diameter of the insertion hole 52'.

[0105] 25 to 28 are diagrams showing the procedure for assembling the parts shown in FIG. 23 onto a vehicle body.

[0106] Referring to FIG. 25, the shape-deformed nut portion 300'' of the component unit 1 is shown before being inserted into the insertion hole 52' of the body panel 50'.

[0107] Referring to Figure 26, this shows the shape-deformable nut portion 300" of the component unit 1 after it has been inserted into the insertion hole 52' of the vehicle body panel 50'. In other words, when the shape-deformable nut portion 300" is inserted into the insertion hole 52' of the vehicle body panel 50', the inclined wing 320" is elastically deformed downward and then restored to its original shape so that it is hung on the outer surface of the vehicle body panel 50'.

[0108] When the deformed nut part 300" is inserted into the insertion hole 52', the six-point guide protrusion 9 is seated on the outer periphery of the inner horizontal bent piece 45 as shown in FIG. 32, and the grip 4 is accurately positioned in the slip pull-out hole 44. In addition, the front surface of the housing 5 is also inserted into the component insertion hole 55, and the guide cover 70 is also inserted while matching with the inner peripheral surface of the inner horizontal bent piece 45.

[0109] 27, when the guide protrusion 9 is seated on the outer periphery of the inner horizontal bent piece 45, the bolt part 200 and the screw bushing 150 move forward due to the force of the tool pressing the bolt part 200, i.e., the force of the headed washer 230 pressing the rear end of the screw bushing 150. The screw bushing 150 moves freely with a large screw angle, and automatically corrects only the gap with the body panel 50' inside the vehicle body.

[0110] 28, with the front surface of the screw bushing 150 abutting against the inner surface of the vehicle body panel 50', the inclined wings 320" of the deformable nut part 300" are hooked onto the outer surface of the vehicle body panel 50' and cannot rotate due to the anti-rotation piece 54'. If the tool continues to operate, the bolt part 200 will rotate to its original place and the nut 310" will move backward along the male threaded rod 220. Then, the inclined wings 320" will be folded and spread out, and while still hooked onto the outer surface of the vehicle body panel 50', they will be pressurized together with the screw bushing 150. The screw bushing 150 acts as a stopper between the bolt part 200 and the deformable nut part 300".

[0111] 29 and 30 are perspective views showing the parts before and after a guide cover is assembled, and FIG. 31 is a perspective view showing the parts in FIG. 30 joined to a vehicle body.

[0112] 29 to 30, a vehicle body assembly structure according to an embodiment of the present invention includes a guide cover 70. The guide cover 70 covers the grip 4 of the flush handle. The guide cover 70 coincides with the grip pull-out hole 44. The front surface of the guide cover 70 protrudes outward from the grip pull-out hole 44.

[0113] The guide cover 70 ensures skin conformity.

[0114] (1) Due to the characteristics of the flush handle, it is important to ensure that the design of the vehicle exterior body panel 40 and the grip 4 match (matching of the skin surface / matching of gaps without product bias).

[0115] (2) The 6-point guide protrusion 9 and the double guide structure that can secure the correct position are used to precisely seat the grip in the grip hole 44.

[0116] (3) The six-point guide protrusion 9 and the guide cover 70 are used to double guide the fastening modules 10, 10', and 10'', which are stable and have a tolerance structure. The guide cover 70 is then removed to complete the process (the guide cover removal tool can be recycled).

[0117] The above-mentioned embodiments of the present invention or other embodiments are not mutually exclusive or distinct, and the configurations or functions of the above-mentioned embodiments of the present invention or other embodiments may be used together or combined.

[0118] It is obvious to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. The above detailed description should not be construed as limiting in all respects, but should be considered as illustrative.
