Abstract
The present invention relates to a component unit and a vehicle body assembly structure. More particularly, the present invention relates to a component unit and a vehicle body assembly structure in which the assembly ability of components with a vehicle body such as an arcuate surface is significantly improved.
Description
Technical Field
The present invention relates to a component unit and a structure for assembling a vehicle body. More particularly, the present invention relates to a component unit and a vehicle body assembly structure in which the assembly ability of components with a vehicle body such as an arcuate surface is significantly improved.
Background
Conventional vehicle body assembly structures control proper dimensional tolerances of the vehicle body and the components when the components are assembled to the vehicle body.
However, in one patent document (korean patent No. 10-2419003), since the anti-rotation piece that prevents rotation of the nut is formed by bending at one side of the nut insertion hole of the vehicle body inner panel, it is possible to increase the size of the hole of the vehicle body inner panel. Therefore, the strength of the vehicle body inner panel may be weakened.
In particular, in one embodiment of the patent document (see fig. 1 to 16), it is necessary to form a hole separate from the nut insertion hole to bend the anti-rotation piece, and a groove communicating with the nut insertion hole is formed. Therefore, the strength of the vehicle body inner panel is inevitably weakened.
In one embodiment of this patent document (see fig. 1-16), a 3-stage assembly is involved, as it is first inserted into the nut socket and then moved to the slot, followed by tightening.
In addition, in another embodiment of the patent document (see fig. 17-28), the nut cannot be reused after tightening because the shape of the nut is deformed during use.

The inclined plates 153 may be disposed at intervals of 120 degrees. As shown in fig. 6, when the male threaded rod 220 of the bolt portion 200 is inserted into the space formed at the end portions of the three inclined plates 153, the three inclined plates 153 may hold the bolt portion 200 to improve the clearance of the bolt portion 200, and may allow the male threaded rod 220 to move in the direction (xz direction) of raising the inclined plates 153, thereby significantly improving the fastening efficiency.
Further, a hook 154 may be formed at the front end portion of the swash plate 153. The hooks 154 may be caught on the threads of the male threaded rod 220 of the bolt portion 200 to prevent the bolt portion 200 from being pushed rearward. The hooks 154 fix the position of the male threaded rod 220 and thus can always maintain the initial use position during product assembly and transportation and prevent the bolts from separating.
The three swash plates 153 can provide a flexible structure capable of preventing the bolt portion 200 from being pushed backward, maintain a center origin (fixed XZ reference point for tool use) between the threaded bushing 150 and the bolt portion 200, prevent sliding between the threaded bushing 150 and the bolt portion 200 (improve noise factors such as impact sounds), and collect tolerances by adjusting XZ directions.

Referring to fig. 5 and 6, the fixing module 10 may include a nut portion 300. The nut portion 300 may include a nut 310. Referring to fig. 9-11, a nut 310 may be fixed on a male threaded rod 220 protruding forward from the front surface of the threaded bushing 150.
The nut portion 300 may include a tab 330. Tabs 330 may protrude leftward and rightward from the outer circumferential surface of the nut 310.
Accordingly, when the nut portion 300 rotates the bolt portion 200 after the nut portion 300 is inserted from the inside to the outside of the body member 30 and passes through the body member 30, the nut portion 300 may contact and tighten the inner and outer surfaces of the body member 30 by moving the screw bush 150 forward after the tab 300 moves backward.
The vehicle body assembly structure according to the embodiment of the invention may include the vehicle body member 30.
Referring to fig. 1-4, the body member 30 may include an exterior body panel 40. The body outer panel 40 may be an outer panel having an arcuate surface. The exterior body panel 40 may include a grip retraction aperture 44. The grip 4 may be disposed in the grip retraction aperture 44.
The body member 30 may include a body inner panel 50. The body inner panel 50 may be installed separately from the body outer panel 40.
As shown in fig. 4, the body inner panel 50 may include an assembly hole 51. The assembly hole 51 may be a quadrangular hole penetrating forward and backward. The assembly hole 51 may have a size sufficient for the rotation blocking portion 140 to pass through.
The body inner panel 50 may include a component receptacle 53. As shown in fig. 3, the front surface of the housing 5 of the component 3 is insertable into the component insertion hole 53. In this case, the fixing module 10 may be disposed in the vehicle body inner panel 50 to face the assembly hole 51.
Fig. 13-20 illustrate steps in assembling the component 3 of fig. 2 to a body component 30.
Fig. 13 and 14 are perspective and side views showing the rotation blocking portion 140 of the fixing module 10 after being inserted into the assembly hole 51 of the vehicle body inner panel 50.
When the rotation blocking portion 140 is inserted into the assembly hole 51 as shown in fig. 13 and 14, the tab 330 of the nut portion 300 is separated from the seat piece 145 when the bolt portion 200 is rotated in the fastening direction as shown in fig. 15 and 16, and the tab 330 is rotated until the tab 330 is caught on the rotation blocking claw 143.
As shown in fig. 15 and 16, the tab 330 caught on the rotation blocking jaw 143 is not rotated any more, and the nut 310 is moved backward along the male threaded rod 220 by rotating the bolt portion 200. Accordingly, as shown in fig. 17 and 18, the nut 310 moves to the outer surface of the vehicle body inner panel 50 and then is caught.
As shown in fig. 19 and 20, the bolt portion 200, which rotates with respect to the non-moving nut 310, moves forward while rotating with the threaded bushing 150, and moves to the inner surface of the vehicle body inner panel 50 and then gets stuck.
As shown in fig. 19 and 20, when the tab 330 and the threaded bushing 150 rotate the bolt portion 200 even after being caught on the inner and outer surfaces of the vehicle body inner panel 50, the tab 330 and the threaded bushing 150 can be prevented from loosening by the saw-tooth protrusions of the nut 310 and the bolt portion 200 and can be fastened in close contact with the inner and outer surfaces of the vehicle body inner panel 50.
Some embodiments of the invention described above, or other embodiments, are not mutually exclusive or different from each other. The configurations or functions of some or other embodiments of the invention described above may be used together or in combination with one another.
