Description

  The present invention relates to an assembly structure of a dash insulator for automobiles suitable for assembling a dash insulator to an automobile and its dash panel.

  Conventionally, as a technique for assembling a dash insulator employed in an automobile to a dash panel of the automobile, a sound insulating material fixing structure described in Patent Document 1 has been proposed.

  In the fixing structure, a structure in which an upper portion of the dash insulator is fixed to a vehicle body panel that is a dash panel by a bracket is employed.

  The bracket is attached to the upper portion of the vehicle body panel with upper and lower side mounting flanges. Moreover, in the said bracket, the bracket main body has stood up from the up-and-down both sides attachment flange to the vehicle interior side in the U shape. Here, on the upper and lower side surfaces of the bracket main body, each pressing flange is formed by cutting and raising.

  Thus, when the upper portion of the dash insulator is fixed with the bracket configured as described above, the bracket main body of the bracket is inserted into the opening formed in the upper portion of the dash insulator. At this time, the opening portion of the dash insulator is inserted into the upper portion of the dash panel over the holding flange with respect to the bracket body. Accordingly, the dash insulator is pressed against the upper portion of the dash panel by the pressing flanges between the upper portion of the dash panel and the pressing flanges at the upper and lower edges of the opening.

Japanese Utility Model Publication No. 6-44242

  By the way, in the above-mentioned fixing structure, the opening of the dash insulator is formed in a rectangular shape so as to correspond to the outer shape of the bracket body. Therefore, as described above, the dash insulator is held on the upper part of the dash panel by the holding flanges between the upper part of the dash panel and the holding flanges at the upper and lower edges of the rectangular opening. However, when the dash insulator hangs downward at the lower edge of the opening due to the weight of the dash insulator, the dash insulator is lifted from the lower pressing flange by a reaction force at the upper portion. It comes off from the bracket body to the vehicle interior side, causing a problem that it is difficult to fix to the upper part of the dash panel.

  Therefore, in order to deal with the above-described problems, the present invention makes use of a plate-like bracket for positioning the upper portion of the instrument panel, and devised a structure for assembling the dash insulator with respect to the plate-like bracket. It is an object of the present invention to provide an assembly structure for an automobile and a dash insulator for an automobile in which the upper part is assembled to be firmly held on the upper part of the boundary wall member between the engine room and the passenger compartment.

In solving the above problems, an automobile according to the present invention is as described in claim 1.

In the car,
Comprising a plurality of plate-like brackets (70, 80, 90) extending rearward from the upper part (31, 30a) of the boundary wall member in the left-right direction;
In the dash insulator, a plurality of slit-like insertion portions (61c, 61d, 61e, 61j) are formed in the upper insulator portion so as to allow a plurality of plate-like brackets to be inserted into the vehicle interior side at intervals in the left-right direction. And
The instrument panel is a plurality of engaging members extending from the front-rear direction intermediate portion to the plurality of plate-like brackets at intervals in the left-right direction, and a plurality of plate-like shapes at each extending end. A plurality of engaging members (40c) that engage with each extending end of the bracket are provided,
The dash insulator is held at each slit-like insertion portion so as to be opposed to the upper side portion of the boundary wall member by a plurality of plate-like brackets via the left and right intermediate portions (73, 83, 91a) in the front-rear direction. Thus, it is assembled to the boundary wall member.

  In this way, the dash insulator is held by the plurality of plate-like brackets at the respective slit-like insertion portions of the upper insulator portion so as to face the upper portion of the boundary wall member via the respective intermediate portions on the left and right sides in the front-rear direction. And assembled to the boundary wall member.

  Here, each insertion part of the dash insulator is formed in a slit shape as described above. For this reason, even if the dash insulator causes a drooping phenomenon due to its weight, each slit-like insertion portion of the dash insulator is deformed due to the drooping phenomenon and does not form an opening, so that it has a good slit shape. Can be maintained. For this reason, each said slit-shaped insertion part can be firmly hold | maintained via the each front-back direction left-right both-sides intermediate part by several plate-shaped brackets. As a result, the subsequent assembly of the instrument panel to the boundary wall member can be properly performed without causing the slit-like insertion portions of the upper insulator portion to be detached from the corresponding plate-like brackets.

And the upper part of the boundary wall member.

  Thus, each plate-like bracket is formed with the above-described configuration of the lower connecting portion, the upper connecting portion, and the left and right side locking pieces. Along with this, as described above, the dash insulator is expanded from the left and right side locking pieces while being expanded to the left and right sides by the left and right side locking pieces of the plurality of plate-like brackets at the slit insertion portions. It is dissociated and held between the left and right locking pieces and the upper part of the boundary wall member.

  Therefore, each slit-shaped insertion part is maintained in a good slit shape as described above by dissociating from each left and right side locking pieces by its elasticity, and returning to the original shape as described above. It can be held firmly between the upper part of the boundary wall member.

  Here, as described above, the left and right side locking pieces extend outward from the intermediate portions on both sides in the extending direction of the upper connecting portion of the plate bracket. Therefore, the sagging due to the weight of the dash insulator can be more effectively suppressed. As a result, in combination with maintaining the good slit shape of the slit-shaped insertion part by configuring the left and right side locking pieces as described above, the operational effect of the invention according to claim 1 is further improved. It can be further improved.

The dash insulator is attached to the U-shaped main body so that it is widened to the left and right by the U-shaped main body at the left and right inner edges of each insertion hole, and is opened to the left and right by the left and right tongues. When inserted into the left and right side recesses, it is held by the left and right side recesses.

  Thus, each plate-like bracket was formed so as to have both upper and lower flanges and a U-shaped body in the above-described configuration. Accordingly, as described above, the dash insulator is expanded to the left and right by the U-shaped body against the elasticity at the left and right inner edges of each insertion hole, and at the left and right both sides by the left and right tongues. When it is inserted into the U-shaped main body so as to be opened in a double-sided manner and reaches the left and right recesses, it returns to its original shape by elasticity and is held by the left and right recesses.

  Here, as described above, when the insertion holes reach the left and right concave portions of the U-shaped main body, the insertion holes can return to the original shape by elasticity and be firmly held by the left and right concave portions. In addition, each insertion hole portion returns to the original shape as described above, so that the upper and lower side walls of the U-shaped main body are between the upper and lower inner edge portions and the left and right both side tongue pieces in each insertion hole portion. , And can be held in a slit shape.

As shown in FIG. 3, 61c is formed in a slit shape and a "U" shape with a central slit portion 61d and left and right side slit portions 61e.

  Specifically, the central slit portion 61d is formed by cutting the corresponding portion of the thin portion 61a with respect to the groove portion 43a of the corresponding engaging member 40c in the left-right direction, and the length in the left-right direction of the central slit portion 61d is This corresponds to the lateral width of a connecting wall 71 of a bracket 70 described later.

  As shown in FIG. 3, the left and right side slit portions 61e are cut in parallel to each other downward from the left and right ends of the central slit portion 61d with respect to the thin portion 61a, thereby forming a “U” shape together with the central slit portion 61d. The insertion portion 61c is formed. Here, the downward cut length from the left and right end portions of the central slit portion 61d of the left and right side slit portions 61e corresponds to the vertical width of the upper side wall portion 72b of each side wall 72 of the bracket 70 described later.

  In the first embodiment, the slit-like insertion portion 61d cuts out the portion of the thin portion 61a of the corresponding upper insulator portion 61 in a U-shape along the cut-out directions of the central slit portion 61d and the left and right side slit portions 61e, By forming a rectangular tongue 61f (see FIG. 5), it is formed between the tongue 61f. The tongue piece 61f can be bent in the front-rear direction against the elasticity with the lower end portion as a reference.

  As shown in FIG. 1, the middle insulator 62 extends integrally downward from the lower end of the upper insulator 61 along the lower part of the upper panel 31 and the middle panel 32. Yes. This means that the dash insulator 60 is formed in a “U” shape that is gently convex rearward from the upper insulator portion 61 to the middle insulator portion 62 (see FIG. 2).

  Further, the lower insulator 63 extends integrally downward from the middle insulator 62 along the lower panel 33. This means that the dash insulator 60 is formed in a “U” shape that is gently convex from the middle insulator portion 62 to the lower insulator portion 63 toward the front obliquely downward direction (FIG. 1). reference).

  Further, as shown in FIG. 2, the automobile includes a plurality (for example, four) of brackets 70 having an L-shaped longitudinal section. As can be seen from FIG. 2 or FIG. 4, each of these brackets 70 is assembled to the upper panel portion 31 of the dash panel 30 from the inside of the vehicle compartment 20 and is engaged with each corresponding via each corresponding slit-like insertion portion 61 c. The bracket 70 is positioned so as to correspond to the member 40c, and the bracket 70 does not serve to position the instrument panel 41 but holds the dash insulator 60 in an undisplaceable state by the upper insulator portion 61 as described below. It is a dual-purpose bracket that also plays a role.

  Since the plurality of brackets 70 are both formed to have the same configuration, the configuration will be described by taking one bracket 70 of the plurality of brackets 70 as an example.

It is fixed from the inside of the passenger compartment 20 to the corresponding portion of the upper panel portion 31 with respect to 40c (see FIG. 2). The upper connecting wall 71b is integrally formed so as to be bent and extend in an L shape from the upper end of the lower connecting wall 71a toward the groove 43a of the corresponding engaging member 40c. As described above, the lateral width of the upper connecting wall portion 71b is equal to the lateral length of the central slit portion 61d of the slit-like insertion portion 61c. This is because the upper connecting wall portion 71b can be inserted into the central slit portion 61d. In addition, the left-right direction width | variety of the upper side connection wall part 71b is wider than the left-right direction width | variety of the groove part 43a of the engaging member 40c.

  As shown in FIG. 5 or FIG. 6, the left and right side L-shaped side walls 72 have a lower side wall portion 72 a and an upper side wall portion 72 b, respectively. In the left and right side L-shaped side walls 72, both lower side wall portions 72a are bent in an L shape rearward from the left and right ends of the lower connection wall portion 71a of the L-shaped connection wall 71 and extend integrally.

It extends to the left so as to be perpendicular to 73a. Further, the inclined side portion 73c of the left side locking piece 73 is formed in an inclined shape from the extending end portion of the front side portion 73b to the rear end portion of the bottom side portion 73a, and together with the bottom side portion 73a and the front side portion 73b, The left locking piece 73 is configured in a right triangle shape.

  On the other hand, the right side locking piece 73 is bent in an L shape from the center lower end in the front-rear direction of the upper side wall portion 72b of the right side wall 72 to the right side so as to have a symmetrical configuration with the left side locking piece 73 in the left-right direction. Thus, it is formed in a right triangle shape so as to extend integrally.

  Here, the right side locking piece 73 is integrated with the lower end in the front-rear direction of the corresponding upper side wall part 72b at the bottom side part 73a, and the front side part 73b of the right side locking piece 73 is It extends rightward so as to be perpendicular to the bottom side 73a (see FIGS. 4 and 6). In addition, the inclined side portion 73c of the right side locking piece 73 is formed in an inclined shape from the extending end portion of the front side portion 73b to the rear end portion of the bottom side portion 73a. It is configured in a right triangle shape symmetrical to the piece 73 (see FIG. 6).

  In the first embodiment, in the left and right side locking pieces 73, the extension length of each front side portion 73 b and the inclination angle of each inclined side portion 73 c with respect to each corresponding bottom side portion 73 a are determined by the left and right side locking pieces 73. The respective values are selected so as to return to the original shape after being inserted into the corresponding left and right side slit portions 61e while being sequentially expanded to the left and right along the corresponding inclined side portions 73c against the elasticity.

  In one bracket 70 configured as described above, the L-shaped connecting wall 71 is inserted into the central slit portion 61d of the corresponding slit-shaped inserting portion 61c at the upper connecting wall portion 71b, and the left and right side L-shaped. The side walls 72 are inserted into the left and right side slit portions 61e of the corresponding slit-like insertion portions 61c by the upper side wall portions 72b and the left and right engaging pieces 73, and the upper connection wall portions 71b are instrumented. The panel module 40 engages with the groove 43a of the corresponding engagement member 40c of the corresponding panel module 40, and is disengaged from the groove 43a of the corresponding engagement member 40c and faces the left and right space portions.

  Here, in the left and right L-shaped side walls 72, each upper side wall portion 72b is inserted through the left and right side slit portions 61e along the vertical direction thereof, while each of the left and right side locking pieces 73 is formed on the left and right side slit portions 61e. The left and right side slit portions 61e are inserted while being expanded to the left and right against the elasticity at the intermediate portion in the vertical direction.

These remaining brackets 70 are fixed from the inside, and the upper connection wall portions 71b of the one bracket 70 described above are connected to the upper connection wall portions 71b, the upper side wall portions 72b, and the left and right side locking pieces 73, respectively. Similarly to the upper side wall portions 72b and the left and right side locking pieces 73, the remaining corresponding slit-like insertion portions 61c are inserted into the corresponding upper side wall portions 72b and the remaining corresponding engagement members 40c. The upper side wall portions 72b are opposed to the left and right space portions of the groove portions 43a of the corresponding engaging members 40c.

  In FIG. 1, reference numeral 23 denotes a carpet. The carpet 23 extends from the middle portion in the vertical direction of the middle insulator 62 of the dash insulator 60 to the front end of the tibia pad 22 in the passenger compartment 20. The insulator main body 60b is disposed along the rear surface and the top surface of the tibia pad 22. Further, in FIG. 1, symbols H and S indicate a steering mechanism and a driver's seat of the automobile, respectively, and the steering mechanism H is assembled to the dash panel 30 via the instrument panel module 40.

  In this 1st Embodiment comprised as mentioned above, the assembly | attachment with respect to the dash panel 30 of the instrument panel module 40 and the dash insulator 60 is performed as follows.

  First, as illustrated in FIG. 5, the plurality of slit insertion portions 61 c of the upper insulator portion 61 of the dash insulator 60 correspond to the corresponding brackets 70 as illustrated in FIG. 5. The insulator 60 is opposed to the dash panel 30 from the inside of the passenger compartment 20.

  Thereafter, the dash insulator 60 is moved in the horizontal direction toward the dash panel 30 and assembled to the dash panel 30. This assembly is performed by fixing the middle insulator portion 62 and the lower insulator portion 62 of the dash insulator 60 to the middle panel portion 32 and the lower panel portion 33 of the dash panel 30 at a plurality of left and right sides. .

  In such an assembling process, the upper connection wall portions 71b of the corresponding bracket 70 are located on the left and right sides of the slit insertion portions 61c with respect to the plurality of slit insertion portions 61c of the upper insulator portion 61. Together with the side wall portion 72b and the left and right side locking pieces 73, the slit-shaped insertion portion 61c is inserted.

  In such a stage, for each slit-like insertion portion 61c, the upper connecting wall portion 71b is inserted into the central slit portion 61d of the corresponding slit-like insertion portion 61c, and the upper side wall portion 72b is the corresponding slit-like insertion portion. The left and right slit portions 61e of 61c are inserted.

  With this insertion, after the plurality of slit-like insertion portions 61c reach the left and right side locking pieces 73 of the corresponding bracket 70 at the left and right side slit portions 61e for each slit-like insertion portion 61c, the dash insulator is further added. By moving 60 to the dash panel 30 side, the plurality of brackets 70 are inserted into the corresponding slit-shaped insertion portions 61 c by the left and right side locking pieces 73 for each bracket 70.

  Here, as described above, in the left and right side locking pieces 73, the extension length of each front side portion 73 b and the inclination angle of each inclined side portion 73 c with respect to each corresponding bottom side portion 73 a are determined by the left and right side locking pieces 73. Along each corresponding inclined side portion 73c, the left and right side slit portions 61e of the corresponding slit-like insertion portion 61c are sequentially expanded to the left and right against elasticity, and then inserted into the left and right side slit portions 61e, and then returned to the original shape. Each value is selected as the value to obtain.

  For this reason, with respect to the plurality of slit-like insertion portions 61c, the left and right side locking pieces 73 of the corresponding bracket 70 are orthogonal to the left and right side slit portions 61e of the slit-like insertion portion 61c for each slit-like insertion portion 61c. When inserted against the elastic force, the left and right side locking pieces 73 extend along the respective inclined side portions 73c and the left and right side slit portions 61e of the corresponding insertion portion 61c are sequentially expanded to the left and right at the intermediate portion in the vertical direction. However, it is inserted into the left and right side slit portions 61e. At this time, the left and right side locking pieces 73 are inserted into the left and right side slit portions 61e along the respective inclined side portions 73c while bending the tongue piece 61f rearward against its elasticity.

  Thereafter, each of the plurality of slit-like insertion portions 61c escapes from the corresponding inclined side portions 73c to the dash panel 30 side for each slit-like insertion portion 61c, so that the corresponding bracket 70 has its left and right side locking pieces. In 73, it is inserted so as to be dissociated from the corresponding left and right side slit portions 61e.

  And in connection with this, the some slit-shaped insertion part 61c returns to an original shape for every slit-shaped insertion part 61c. At this time, for each slit-like insertion portion 61c, the tongue piece 61f bent rearward as described above is pushed back from the front to return to the original shape, thereby returning the slit-like insertion portion 61c to the original shape. Made.

  Further, since the slit-shaped insertion portion 61c is restored to the original shape as described above, the slit-shaped insertion portion 61c is caused by the drooping phenomenon even if the dash insulator 60 causes the dripping phenomenon due to its weight. It is maintained in a good slit shape without deforming and forming an opening. For this reason, the upper connecting wall 71b of the bracket 70 can be firmly held and held in the central slit 61d, and the upper side walls 72b of the bracket 70 can be firmly held and held in the left and right side slits 61e. Therefore, the left-right extension shape of the left and right side locking pieces 73 in each bracket 70 is combined with the favorable slit shape of each slit-like insertion portion 61c to suppress the descent of the dash insulator 60 due to its weight to a minimum. Can do.

  At this time, the interval between the left and right side locking pieces 73 and the upper panel portion 31 is equal to the interval between the corresponding slit-shaped insertion portion 61c and the surface of the upper panel portion 31 inside the vehicle compartment 20 as described above. Therefore, the plurality of slit-like insertion portions 61c are displaceable between the left and right locking pieces 73 of the corresponding bracket 70 and the upper panel portion 31 at the inner peripheral edge of each slit-like insertion portion 61c. Can be retained.

  Therefore, in such a state, even if the upper insulator portion 61 tries to be displaced toward the inside of the passenger compartment 20 by the elasticity with respect to the middle insulator portion 62, the plurality of slit-like insertion portions 61c are respectively connected to the corresponding brackets. The dash insulator 60 can be held firmly with respect to the upper panel portion 31 by the upper insulator portion 61 by being held without being disengaged from the inside 70 of the vehicle interior 70. At this time, each bracket 70 passes through the corresponding slit-like insertion portion 61c together with the corresponding left and right side locking pieces 73 at the upper connecting wall portion 71b and the upper side wall portions 72b located on both sides thereof. Extends inward.

  At such a stage, the instrument panel module 40 is arranged so that the connecting member 40c faces the corresponding slit-like insertion portion 61c of the dash insulator 60, as illustrated in FIG. Arranged inside the chamber 20.

  Thereafter, when the instrument panel module 40 is moved in the horizontal direction toward the dash panel 30 as it is, the instrument panel 41 has a lower end of the front windshield 50 at its upper front end 41a as shown in FIG. Abuts against the part. At this time, the upper front end portion 41a of the instrument panel 41 is bonded to the lower end portion of the front windshield 50 via the band-shaped soundproof member 41b.

  Along with this, each engagement member 40c of the instrument panel module 40 engages the upper connection wall portion 71b of the corresponding bracket 70 in the groove portion 43a at the tip portion thereof. As described above, this engagement is achieved by connecting the plurality of slit-like insertion portions 61c between the left and right side locking pieces 73 of the corresponding bracket 70 and the upper panel portion 31 for each slit-like insertion portion 61c. In the meantime, it can be reliably achieved by being held in an undisplaceable state by the upper connecting wall 71b and the upper side wall 72b of the corresponding bracket 70.

  Further, in the state in which the instrument panel module 40 is assembled in this way, even if the automobile is vibrated due to its running or the like, the plurality of slit insertion portions 61c are respectively connected from the corresponding brackets 70 to the vehicle compartment 20. There will be no inward movement.

Further, in the state where the dash insulator 60 is assembled to the dash panel 30 via the brackets 70 as described above, the slit insertion portions 61c of the dash insulator 60 are connected to the upper side of the brackets 70 at the inner peripheral edge thereof. Since it is in contact with the wall portion 71b and the upper side wall portions 72b, transmission of noise such as engine sound from the engine room into the vehicle compartment 20 can be well blocked.
