Description

The present invention
A first locking portion and a second locking portion are provided on a mounting component mounted on the instrument panel body,
A first locked portion and a second locked portion are provided on the instrument panel body;
The present invention relates to a mounting structure for an instrument panel mounting component in which the first locking portion is locked to the first locked portion and the second locking portion is locked to the second locked portion.

In the instrument panel main body in front of the passenger seat of the automobile, an air bag pop-out opening (also an air bag attachment hole to which the air bag device is attached) is formed on the upper surface portion. When the automobile receives an impact, the airbag main body built in the instrument panel main body instantly jumps out of the airbag outlet and protects the passenger on the passenger seat.
Such an airbag device for the passenger seat may not be required depending on the destination. That is, there are destinations that require an airbag device and destinations that do not. Therefore, one of the first specification in which the airbag device is built in the instrument panel body in front of the passenger seat and the second specification in which the airbag device is not built-in is selected corresponding to the destination. In the case of the vehicle of the second specification, it is not necessary to form an air bag outlet in the instrument panel body.
However, when two types of instrument panel bodies are formed: an instrument panel body in which an air bag outlet is formed and an instrument panel body in which an air bag outlet is not formed, parts management (instrument panel body Management) takes time. In addition, there is a problem that the mold cost is increased and the workability at the time of formation is also deteriorated.
In order to solve these problems, an air bag outlet is formed in the instrument panel body of any specification. In the case of the second specification vehicle, the airbag outlet of the instrument panel body is covered with a cover. The cover can be cited as an example of the mounting part described at the beginning.
In the instrument panel body of the second specification, since the airbag device is not built in, a relatively large space is formed in the instrument panel body below the airbag outlet. Therefore, in such a structure, when a strong impact is applied to the surface of the cover from the vehicle interior side, the cover is greatly bent.
As a result, a large force acts on the first locking portion and the first locked portion, the second locking portion and the second locked portion, and the first locking portion and the second locking portion are It is conceivable that the cover is detached from the instrument panel main body by being separated from the first locked portion and the second locked portion. When the cover is removed from the instrument panel body, the projections in the instrument panel body are exposed to the vehicle interior side.
Since this is not preferable, it is necessary to prevent the cover from being detached from the instrument panel body even when the surface of the cover is subjected to a strong impact from the vehicle interior side. As a means for that, there has been a technology in which a detachment prevention structure disclosed in Patent Document 1 has been conventionally used for a cover and an instrument panel body.
In this technique, a locking claw as a first locking portion and an insertion guide extending longer than the locking claw in the insertion direction of the locking claw are provided on the back side of the cover. In addition, a guide hole through which the insertion guide is inserted is provided in the instrument panel body. Then, a pair of other locking claws that are locked to the guide hole when the locking claw of the cover is released from the locked portion of the instrument panel main body are provided at the distal end portion of the insertion guide portion. The pair of other locking claws are displaced from each other in the longitudinal direction of the insertion guide.

Japanese Patent No. 4108494

In the above-described conventional structure, the insertion direction (assembly direction) of the cover insertion guide with respect to the guide hole of the instrument panel main body is the same as the direction in which the cover is removed from the instrument panel main body.
Therefore, when a strong impact is applied to the surface of the cover, both of the pair of other locking claws may be detached from the guide hole. Moreover, since it is necessary to assemble | attach the said pair of latching nail | claw to an instrument panel main body at the time of an assembly | attachment, an assembly property is bad.
An object of the present invention is to provide an instrument panel mounting component mounting structure in which a mounting component such as a cover is unlikely to be detached from the instrument panel main body and the mounting property of the mounting component to the instrument panel main body is good.

  Since the erection part 18 is installed between the pair of claw parts 16, the strength of the pair of claw parts 16 can be increased and the durability of the claw part 16 can be improved.

  The erection portion 18 is located on the front side (front of the locking operation direction) of the claw portions 16 of the pair of locking claws 14 in the locking operation direction A (assembly direction, see FIGS. 4 and 6) of the locking claws 14. And in the protruding direction 16T of the claw portion 16 (see FIG. 6), the claw portion 16 is located on the front side (front side in the protruding direction) of the top portion of the claw portion 16.

  Thereby, the said locking hole 42 becomes wide and the workability | operativity (assembly property) of the assembly work at the time of locking the said locking hole 42 to the 2nd to-be-latched part 32 can be improved.

  As shown in FIG. 10, the locking operation direction A of the locking claw 14 is a direction from the design surface 11M side of the cover 11 to the back surface 11U side, and a direction from the upper side to the lower side.

  As shown in FIGS. 4 and 8, a pair of left and right screw mounting bosses 21 are erected separately on the rear surface 11 U of the vehicle rear side Rr at both left and right ends of the cover 11 via a pedestal 22. The screw mounting boss 21 rises from the back surface 11U of the cover 11 so as to be positioned on the vehicle front side Fr from the lower side (see FIG. 8). The screw mounting boss 21 includes a screw hole 21H that opens toward the back side of the cover 11.

[Structure of the air bag outlet 7 of the instrument panel body 2]
As shown in FIGS. 3 and 8, the second peripheral wall 23 that protrudes from the peripheral edge of the airbag outlet 7 of the instrument panel body 2 to the back side (lower side) of the airbag outlet 7 is an airbag outlet. 7 is provided over substantially the entire circumference.

  Further, a cover mounting wall 24 that projects from the end of the second peripheral wall 23 on the back side of the airbag pop-out port 7 toward the center side of the air bag pop-out port 7 is provided in a flange shape.

  The vehicle front-rear direction middle portions of the cover mounting walls 24 on the left and right sides are formed as recesses 25 that are recessed on the back side of the airbag outlet 7. A first screw insertion hole 26 </ b> H is formed in the vehicle rear side Rr portion of the bottom wall 26 of the recess 25.

  In addition, a plurality of square holes and a plurality of notches are formed in the cover mounting wall 24 so as to be distributed over the entire periphery of the air bag outlet 7. And the peripheral part of a square hole and the peripheral part of the back side of a notch are comprised by the some 1st to-be-latched part 31 which latches the some latching claw 14 of the said cover 11 separately. Further, among the plurality of cutouts, a portion between the pair of left and right cutouts formed in the cover mounting wall 24 on the vehicle front side Fr constitutes a second locked portion 32 that locks the locking hole 42. Has been.

  The distal end portion of the second locked portion 32 at the center side of the airbag outlet 7 is bent to the back side of the airbag outlet 7 and is formed into a flange 32F (see FIGS. 9 and 10). . The flange 32 </ b> F is inclined so as to move away from the center of the airbag outlet 7 as it becomes the back side of the airbag outlet 7.

[Structure of reinforcement 33]
As shown in FIGS. 2, 8, and 11, a metal plate-like reinforcement 33 is fixed to the steering support pipe 10 located below the airbag outlet 7. The reinforcement 33 includes a pair of left and right legs 34 that rise from the steering support pipe 10 toward the air bag outlet 7 side, and a connecting part 35 that connects the tops of the pair of legs 34.

  The leg portion 34 and the connecting portion 35 are formed with reinforcing beads 36 along the longitudinal direction thereof. Thereby, the reinforcement 33 can be reinforced. A second screw insertion hole 35H is formed at the front end portion (the end portion of the vehicle front side Fr) on the right side (vehicle width direction inner side W1, hereinafter the same) of the connecting portion 35.

[Attachment structure of cover 11 to instrument panel body 2]
As described above, the locking claw 14 is locked to the first locked portion 31 and the locking hole 42 is locked to the second locked portion 32. In the step of attaching the cover 11 to the instrument panel main body 2, as shown in FIG. 10, the cover 11 that is inclined so as to be positioned higher toward the vehicle rear side Rr is moved to the vehicle front side Fr. Accordingly, the locking hole 42 is externally inserted and locked to the second locked portion 32 from the vehicle rear side Rr.

  Then, the end of the vehicle rear side Rr of the cover 11 is pushed downward, and the locking claw 14 is locked to the first locked portion 31. That is, the claw portion 16 of the locking claw 14 is elastically deformed and gets over the first locked portion 31 to be elastically locked to the first locked portion 31.

  As shown in FIG. 10, the locking operation direction A of the locking claw 14 and the first locked portion 31 (the assembling direction, the direction from the top to the bottom), the locking hole 42, and the second hooked portion. The locking operation direction B of the stopping portion 32 (the assembling direction and the direction from the vehicle rear side Rr to the vehicle front side Fr) is substantially orthogonal.

  As shown in FIG. 9, the disengagement direction C (the direction from the lower side to the upper side) in which the cover 11 is removed from the instrument panel main body 2, the locking operation direction B of the locking hole 42 and the second locked portion 32, and Are substantially orthogonal.

[Attachment structure of cover 11 to reinforcement 33]
As shown in FIGS. 3 and 8, the bottom wall 26 of the recess 25 of the right cover mounting wall 24 provided on the instrument panel main body 2 overlaps the right end of the connecting portion 35 of the reinforcement 33 from above. Has been. And the front-end | tip part of the screw attachment boss | hub 21 of the right side provided in the cover 11 is overlaid on the said bottom wall 26 from upper direction.

  In this state, the screw S (corresponding to a fastening member) is inserted into the second screw insertion hole 35H of the connecting portion 35 of the reinforcement 33 and the first screw insertion hole 26H of the bottom wall 26 of the cover mounting wall 24 from below. It is inserted. The screw S is screwed into the screw hole 21H of the screw mounting boss 21. Thereby, the cover 11 can be supported also by the steering support pipe 33, and vibration and the like can be more easily suppressed.

  As shown in FIG. 3, the end portion on the left side (vehicle width direction outer side W <b> 2, the same applies hereinafter) of the connecting portion 35 of the reinforcement 33 is closer to the vehicle width direction than the bottom wall 26 of the concave portion 25 of the left cover mounting wall 24. Located on the inner side W1. Accordingly, the bottom wall 26 of the recess 25 of the left cover mounting wall 24 is not overlapped with the left end of the connecting portion 35 of the reinforcement 33. On the bottom wall 26 of the recess 25 of the left cover mounting wall 24, the tip of the left screw mounting boss 21 provided on the cover 11 is superimposed from above. In this state, the screw S is inserted into the first screw insertion hole 26 </ b> H of the bottom wall 26 of the cover mounting wall 24 from below and is screwed into the screw hole 21 </ b> H of the screw mounting boss 21.

  As described above, the instrument panel body 2 is supported by the steering support pipe 10 via the reinforcement 33 only on the left and right center side of the instrument panel body 2. As a result, vibration during traveling can be efficiently suppressed. Further, the positional relationship among the instrument panel body 2, the cover 11, and the reinforcement 33 for efficient shock absorption can be maintained.

  The fixing portion 37 (see FIG. 8) between the cover 11 and the reinforcement 33 is disposed at a position closer to the passenger seat than the locking structure (see FIG. 10) of the locking hole 42 and the second locked portion 32. Thus, when an impact is applied to the cover 11 from the passenger on the passenger seat, the impact is absorbed by the reinforcement 33 and the impact applied to the locking structure is reduced.

According to the configuration of the present invention,
(1) Since the flange 32F at the tip of the second locked portion 32 is inclined so as to move away from the center of the airbag pop-out port 7 toward the back side of the air bag pop-out port 7, The locking portion 32 can be smoothly inserted and locked without being caught in the locking hole 42.

(2) After the locking hole 42 and the second locked portion 32 are locked, the locking claw 14 and the first locked portion 31 can be engaged with each other. By locking the locked portion 32, the positions of the locking claw 14 and the first locked portion 31 can be determined, and when the locking claw 14 is locked to the first locked portion 31. The workability of the assembly work can be improved.

(3) Since the instrument panel body 2 of the second specification does not incorporate the airbag device, a relatively large space is formed in the instrument panel body 2 below the airbag outlet 7.
Therefore, in such a structure, when a strong impact is applied to the surface of the cover 11 from the vehicle interior side, the cover 11 is greatly bent.
As a result, a large force acts on the locking claw 14 and the first locked portion 31, the locking hole 42 and the second locked portion 32, and the locking claw 14 and the locking hole 42 are in the first locked position. It is conceivable that the cover 11 is detached from the instrument panel main body 2 by detaching from the portion 31 and the second locked portion 32.
However, according to the configuration of the present invention, the disengagement direction C in which the cover 11 is removed from the instrument panel main body 2 and the locking operation direction B of the locking hole 42 and the second locked portion 32 are substantially orthogonal. Therefore, it is possible to prevent the cover 11 from being detached from the instrument panel body 2 when the surface of the cover 11 is subjected to a strong impact from the vehicle interior side.
That is, as shown in FIG. 9, when the cover 11 receives an impact and tries to be removed from the instrument panel main body 2, the installation portion 18 of the cover 11 is moved to the second locked portion 32 (between the pair of left and right cutouts 29 ) (See the two-dot chain line in FIG. 9), the displacement of the installation portion 18 is prevented. Thereby, detachment of the cover 11 from the instrument panel main body 2 can be prevented.

(4) As shown in FIG. 10, the locking operation direction A of the locking claw 14 and the first locked portion 31, and the locking operation direction B of the locking hole 42 and the second locked portion 32. Are substantially orthogonal to each other, so that the locking claw 14 and the first locked portion 31 are locked (assembled), and the locking hole 42 and the second locked portion 32 are locked (assembled). Can be done separately. Therefore, the workability of the assembly work can be improved.

(5) A first locking structure including the pair of left and right locking claws 14 and a pair of left and right first locked portions 31, and a second locking structure including a locking hole 42 and a second locked portion 32. Since they are located close to each other, it is easy to assemble and workability of the assembling work can be improved.

(6) The fixing portion 37 (see FIG. 8) between the cover 11 and the reinforcement 33 is closer to the passenger seat than the locking structure (see FIG. 10) between the locking hole 42 and the second locked portion 32. When the impact is applied to the cover 11 from the passenger on the passenger seat, the impact is absorbed by the reinforcement 33 and the impact applied to the locking structure is reduced. And the second locked portion 32 can be prevented from being released, and the cover 11 can be prevented from falling off from the instrument panel body 2.

(7) That is, as shown in FIG. 8, when the head H of the passenger in the passenger seat collides with the end of the cover 11 on the vehicle rear side Rr and a strong impact is applied to the cover 11, the cover 11 is connected. The impact force is transmitted to the reinforcement 33 and the steering support pipe 10.
Then, the reinforcement 33 is crushed and absorbs the impact. Reference sign K is an impact input direction. As the reinforcement 33 is crushed, the center of the first screw insertion hole 26H formed in the bottom wall 26 of the recess 25 of the left cover mounting wall 24 (see FIG. 3) and the right cover mounting wall 24 The cover 11 rotates around the horizontal axis connecting the center of the first screw insertion hole 26H formed in the bottom wall 26 of the recess 25 (see FIG. 3), and the end of the cover 11 on the vehicle front side Fr is upward. Try to displace. 8 indicates the upward rotation direction of the end portion of the vehicle front side Fr of the cover 11.
However, as shown in FIG. 9, when the cover 11 receives an impact and tries to be removed from the instrument panel main body 2, the installation portion 18 of the cover 11 is received by the second locked portion 32 (FIG. 9). The displacement of the erection part 18 is prevented. Thereby, detachment of the cover 11 from the instrument panel main body 2 can be prevented.

[Another embodiment]
(1) The present invention can also be applied to a structure in which garnish and other parts are attached to the instrument panel body 2. The cover 11 and the garnish are collectively referred to as “mounted parts”.

(2) In the above embodiment, the instrument panel main body 2 is divided into an instrument panel upper 3 and an instrument panel lower 4, but the instrument panel main body 2 is divided into an instrument panel upper 3 and an instrument.
