Abstract

PROBLEM TO BE SOLVED: To provide a structure which prevents a clip head or mounting hole from exposing outside by attaching a clip from inside of a front lid to fix a radiator grille, as well as allows stable detachment of the radiator grille from the front lid by a simple rotational operation without forcedly detaching the clip from the radiator grille and the front lid in detaching the radiator grille in a large vehicle and the like. SOLUTION: A fixed shaft 5b is inserted into a perfect circle hole 7 formed on a front lid 3. After insertion, a stator 5 is fixed onto the front lid 3 by an elastic return force of a latch pawl 5a. A radiator grille 2 is fixed by a latch pawl 4a at a reduced-diameter portion of a slot 6 formed thereon. After insertion, a rotator 4 is fixed onto the radiator grille 2 by an elastic return force of the latch pawl 4a. As a result, the radiator grille 2 is fixed to the front lid via a clip 1. This position is maintained by the sides located in perpendicular relation around a flange 4c constituting a clip stop on a flange receiver 5c.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field related to a structure in which a radiator grill is attached to and detached from a front lid by a clip comprising a stator and a rotor coaxially fitted thereto.

[0002]

2. Description of the Related Art FIG. 14 is an external perspective view of a mounting structure of a radiator grill of a relatively small vehicle. Since it is very difficult to fasten the radiator grill 10 with screws or the like from the engine room side because the working space is narrow, the radiator grill 10 is covered from the outside of the front lid 9 as shown in FIG. Fix from.
Although this method exposes a part of the clip or the mounting hole on the outside of the radiator grill, in a relatively small vehicle, since the human eyes are at a higher position than the radiator grill, the appearance is not enough to impair the appearance. Did not. Further, in order to prevent the appearance from being spoiled, a forced press-in structure as shown in FIG. 15 is employed. The clip 8 is made of an elastic material such as plastic, and has a structure in which the locking claw 8a can be elastically displaced in a direction perpendicular to the clip center axis. The clip 8 is attached to a radiator grill 10 in advance through a mounting hole 12, and is pressed into a mounting hole 11 provided in a front lid 9. After the press-fitting, the locking claw 8a is moved by the elastic return force to the front lid 9 and the radiator grill 10
Is fixed without play. When disassembling and repairing the front lid 9 and the radiator grill 10, remove the radiator grill 10,
The clip 8 is forcibly peeled in the direction opposite to the direction in which the clip 8 was pressed, and the radiator grille 10 is re-assembled by pressing the clip 8 into the front lid 9 as described above. The reason why the forced attachment / detachment method using the clip 8 instead of screwing is adopted is to reduce the number of manufacturing / assembly steps and the number of disassembly / repair steps.

[0003]

The structure for fixing the radiator grill 10 from the outside with the clip 8 as described above is as follows.
When applied to a large vehicle, the head or the clip mounting hole of the clip 8 whose human eyes are exposed to the outside substantially coincides with each other, which may impair the aesthetic appearance. Further, in the structure for preventing the appearance from being impaired, since the clip 8 is forcibly attached to and detached from the hole 11 of the front lid 9, the clip 8 or the front lid 9 and the radiator grill 10 are damaged during repeated attachment and detachment. It is easy to be. Further, in order to avoid such damage, it is possible to reduce the resistance when the clip 8 is pulled away from the mounting hole 11 by pushing the engaging claw 8a of the clip 8 in the direction of the center axis of the clip 8 with a tool or the like. Since this is performed in a small space, the number of disassembling steps is increased, and the original purpose of this structure is not fulfilled. JP-A-9-58382, JP-A-63-765

All of the clip structures 914 are visible from the outside of the radiator grille, or are forcibly detached on the radiator grille side or the front lid side, and do not solve the problem. In Japanese Utility Model Application Laid-Open No. 63-147914, the clip is partially rotated, but the locking claw once inserted is locked so as not to be pushed back inward, and the above problem has not been solved.

Accordingly, the present invention focuses on the fact that the front lid has a structure that can be easily opened and closed as a single part in a large vehicle or the like, and a method of mounting a radiator grill in which clips are previously arranged on the radiator grille is disclosed. By providing a structure that allows easy clip release work inside the lid, the radiator grille can be easily rotated to the front without removing the clip from the radiator grille or the front lid when removing the radiator grille. It is intended to provide a structure that can be stably attached to and detached from the lid.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a stator and a rotor which is fitted coaxially with the stator and does not move relative to each other in the axial direction due to a stopper provided on the stator. A radiator grill is attached to and detached from the front lid by a clip consisting of a rotating shaft having a tool groove and a circular outer peripheral cross section at its end portion for rotating with a general hand tool from the back side of the front lid. A long hole having a substantially polygonal or chrysanthemum-shaped flange, wherein a radiator grill is bored in the radiator grill between the engaging claw that protrudes outside the outer periphery of the rotating shaft and elastically displaces in a direction perpendicular to the axis and the flange. However, at the position where the rotation shaft is rotated 90 degrees from the state of the restriction from the back side of the front lid, the restriction of the radiator grill is It is released through a diameter, and the state of the narrowing and releasing is achieved by fitting with a lip or a flat spring formed on a rectangular flange receiver having a square tray shape disposed on the periphery of the flange and the stator. A locking claw that is stably held, the stator has a fixed shaft having a circular outer peripheral cross section, and the rectangular flange receiver, protrudes outside the outer periphery of the fixed shaft, and is elastically displaced in a direction perpendicular to the axis; and the rectangular flange. During the receiving, the front lid is narrowed through a circular hole drilled in the front lid, but the narrowing is not released by the rotation of the rotating shaft. In the above means, a plurality of openings are provided through the flat plate surface of the rectangular flange receiver provided on the stator in the above means, and adjacent openings among the openings are provided. The flat plate portion remaining between the two openings constitutes a flat spring, and the flat spring comes into contact with the periphery of a flange provided on the rotor, so that the clip can be securely locked and released. Another object of the present invention is to provide a radiator grill attachment / detachment structure using clips that are held.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a three-dimensional perspective appearance of a front portion of a vehicle according to the present invention. Figure 2 shows the radiator grill 2
Is an axial cross-sectional view of a state in which the clip is fixed to the front lid 3 by the clip 1. Before the radiator grill 2 is attached to the front lid 3, a plurality of clips 1 are arranged inside the radiator grill in advance, and
Of the clip 1 is pressed into the front lid 3 and attached. This mounting method is adopted to improve the workability of mounting the radiator grill 2. On the other hand, when the radiator grill 2 is detached from the front lid 3, according to the forcible detachment method, the pull-out force of the clip is greater than the pressure input, so that the fiber-reinforced resin front lid 3 is easily damaged. Therefore, the radiator grill 2 is connected to the front lid 3
In order to remove the clip 1 from the radiator grill 2, the rotor 4 is rotated to release the connection between the clip 1 and the radiator grill 2 without forcibly removing the clip. In the vehicle according to the present embodiment, the front lid 3 can be flipped up and opened by the hinge structure. In this open position, the operator can easily operate the clip from inside the front lid 3. FIGS. 5 to 13 show external views or cross-sectional views of the clip 1. FIG. FIG. 5 shows a rotor 4 and a stator 5 which are components of the clip 1.
1 shows an exploded external perspective view from below. FIG. 6 shows clip 1
1 is an exploded perspective view of a rotor 4 and a stator 5 as components of the present invention as viewed from above. The clip 1 is used in a state where the rotor 4 and the stator 5 are assembled as shown in FIGS.

In FIG. 5, two locking claws 4a are formed at positions symmetrical with each other as a part of the rotating shaft 4b, and have a structure in which they are elastically displaced in a direction perpendicular to the center of the rotating shaft. A rotary head 4e having a flange 4c at a substantially central portion in the longitudinal direction of the rotor 4 and a tool groove 4f at a lower end is disposed. Two locking claws 5a are formed at positions symmetrical with each other as a part of the fixed shaft 5b, and have a structure in which they are elastically displaced in a direction perpendicular to the center of the fixed shaft. A flange receiver 5 is provided on the upper end of the stator 5 in the longitudinal direction.
c, a stopper 5e having a slit 5f at the lower end is provided. In order to assemble the rotor 4 and the stator 5 to constitute the clip 1, as shown in FIG.
Into the hollow portion of the fixed shaft 5b of the stator 5, and the slit 5
f, spreads and passes through the stopper 5e formed by f, and as a result, the stator 5 is held between the flange 4c and the rotary head 4e. 7 and 8 show perspective views of the assembled external appearance of the clip 1. FIG. FIG. 2 shows a center section of the clip shaft in a structure in which the rotor 4 and the stator 5 constituting the clip 1 fix the radiator grill 2 to the front lid 3.

In FIG. 2, a fixed shaft 5b is inserted into a perfect circular hole 7 provided in the front lid 3. After insertion, the stator 5 is fixed to the front lid 3 by the elastic return force of the locking claw 5a. 3 and 4 are AA views of FIG. 2 showing the relationship between the rotating shaft 4b and the mounting portion of the radiator grill 2 as viewed from the radiator grill side. The radiator grille 2 fits the short diameter portion 6a of the long hole 6 shown in FIG. 3 provided therein to the rotating shaft 4b held so that the locking claw 4a is at the position shown in FIG. After the insertion, the rotor 4 is fixed to the radiator grill 2 by the elastic return force of the locking claw 4a. As a result, the radiator grill 2 is fixed to the front lid 3 via the clip 1. As a method of fitting the radiator grill 2 to the rotor 4, in addition to the above-described method, as shown in FIG. 4, the rotor 4 is previously set at a position where the locking claw 4a enters the long diameter portion 6b. After the grill 2 is fitted to the rotor 4, the rotor 4a can be returned to the position shown in FIG. 3 and the short diameter portion 6a can be fixed by the locking claw 4a. Although the position of the rotor 4 in FIGS. 3 and 4 is different from each other by approximately 90 degrees, this position is, as shown in FIG. Slit 5 on 5c
It is held by utilizing the elasticity of the lip 5d separated by h. Since the side portion 4d is located outside the outer periphery of the rotating shaft 4b, a stable position at every 90 degrees is easily secured.

When the radiator grill 2 is to be removed, the rotor 4 is rotated 90 degrees about the axis, and as shown in FIG. 4, the rotor 4 is brought to a position where the locking claws 4a enter the long diameter portion 6b. The fitting of the rotor 4 is released. To rotate the rotor by 90 degrees, a general hand tool is applied to a tool groove 4f provided in the rotary head 4e. The above object can be achieved by either 90-degree rotation or right-rotation. FIG.
Are the hook 4a and the hook 5 in the assembled state of the clip 1.
FIG. 8 shows the locking claw 4a and the locking claw 5 when the a is at the same angle.
The case where a is located at 90 degrees to each other is shown. 9 is a perspective view showing the appearance of the radiator grille 2 when the locking claws 4a fix the radiator grille 2 in the long holes 6 of the radiator grille 2, and FIG. 10 shows the rotor 4 rotated 90 degrees from FIG. FIG. 3 is an external perspective view showing a case where the fixing pawl 4a releases the fixing of the radiator grill 2; In order for the locking claw 4a to secure the holding position with respect to the long hole 6 of the radiator grill 2, the clip 1
Since it is necessary to prevent the whole from rotating, as shown in FIG. 2, the radiator grille 2 is provided with a detent 2a for restraining a part of the outer periphery of the flange receiver 5c.

The front lid 3 is usually formed of fiber-reinforced plastic. However, due to the nature of the fiber-reinforced plastic, the mounting hole 7 must be formed in a separate step after molding. Since the touch-up repair of the plastic after molding is practically very difficult, the mounting hole 7 is not a long hole complicated in the process but a perfect circle in order to avoid erroneous work or scratches in machining. Furthermore, since separation between the radiator grille 2 and the rotor 4 without forced pulling is realized, once the stator 5 is inserted into the perfect circular hole 7, the stator 5 is removed for the purpose of removing the radiator grille 2. There is no need to pull out from the front lid 3. Front lid 3
The reason why the structure is not detachable is to prevent the resin front lid 3 from being damaged due to the large resistance of the locking claw 5a when the pull-out is performed.
When the stator 5 is fitted into the perfect circular hole 7, the elastic resistance of the locking claw 5a is low, so that the front lid 3 is not likely to be damaged. Since the radiator grill 2 is usually manufactured by metal press molding or injection, a separate perforation step for providing a long hole is not required, so that the radiator grill 2 has a structure in which detachment is realized between the radiator grill 2 and the clip.

An embodiment according to the second aspect of the present invention is shown in FIGS. FIG. 11 shows a BB cross section of the stator 5 of FIG. In FIG. 12, the openings 5j and 5k are perforated so that flat springs 5m are formed at both ends of the flange receiver 5c. When the flat spring 5m contacts the substantially chrysanthemum-shaped peripheral portion 4h of the flange 4g provided on the rotor 4, the clip is securely held and released.

1) The radiator grille is attached to and detached from the front lid by a clip comprising a stator and a rotor which is coaxially fitted with the stator and does not move relative to each other in the axial direction due to a retainer provided on the stator. In this structure, the rotor can be rotated at the end by a general tool from the rear side of the front lid, so that it is possible to avoid exposing a part of the clip to the outside of the vehicle which may impair the aesthetic appearance. The radiator grill can be easily and safely attached to and detached from the front lid. 2) The radiator grille is narrowed between the engaging flange, which protrudes outside the outer periphery of the rotary shaft and elastically displaces in the direction perpendicular to the axis, and the polygonal flange, through the short diameter of the long hole formed in the radiator grille. In a position where the rotation shaft is rotated 90 degrees from the state of the restriction from the back side of the front lid, the restriction of the radiator grill is released through the long diameter of the long hole, so that any one of the radiator grill, the front lid, and the clip is used. The radiator grille can be attached to and detached from the front lid without excessive force. 3) The locked state and the released state are stably maintained by fitting a peripheral portion of the flange provided on the rotary shaft with a lip or a flat spring formed on a rectangular flange receiver provided on the stator. Therefore, the radiator grill can be reliably attached and detached with certainty and safety. 4) The front lid is narrowed through a true circular hole formed in the front lid between the locking flange that protrudes outside the outer periphery of the fixed shaft of the stator and elastically displaces in the direction perpendicular to the axis and the rectangular flange receiver. However, since the clip is not released by the rotation of the rotation shaft, the clip is always stably held on the front lid, so that damage to the front lid made of fiber reinforced plastic or the like at the time of attachment / detachment can be avoided. 5) Fiber reinforced plastic, which is the material of the front lid, is easily scratched in the machining process and it is very difficult to correct erroneous operations. Therefore, the machining process is simplified by making the clip mounting hole a perfect circle. Can be
