Description

The present invention
A meter cluster is attached to the instrument panel body on the front side of the driver's seat through the locking means,
The locking means relates to a meter cluster mounting structure comprising a locking claw provided in one of the instrument panel body and the meter cluster, and a locking hole provided in the other.

A steering support member is fixed to the vehicle side portion via a side bracket. The instrument panel is fixed to the steering support member.
In the instrument panel, a meter such as a tachometer or a speedometer is attached to the instrument panel body on the front side of the vehicle in the driver's seat. When direct sunlight enters these meters, it becomes difficult to see the values on the meters. Therefore, a meter cluster covering the periphery of the meter as a garnish is attached to the instrument panel body on the vehicle front side of the driver seat.
The meter cluster is attached to the instrument panel body after the meter or GPS antenna is attached to the instrument panel body.
For this reason, even if the meter cluster is fastened and fixed to the instrument panel main body with screws or the like from the back side of the instrument panel main body, the meter or the GPS antenna becomes an obstacle and the tool does not enter the back side of the instrument panel main body. Moreover, even if a clearance for entering the tool is created, the fastening operation must be performed by hand, resulting in poor workability.
Because of such a problem, the meter cluster is attached to the instrument panel body via a locking means. As described at the beginning, the locking means includes a locking claw and a locking hole.
The instrument panel body on the vehicle front side of the driver's seat is closer to the vehicle side than the instrument panel body at the center of the left and right, so that when the vehicle collides with the vehicle side portion on the driver's seat side, The instrument panel body on the front side is deformed to a greater extent than the instrument panel body on the left and right center. When the instrument panel main body is greatly deformed in this way, the locking claws constituting the locking means may be detached from the locking holes, and the meter cluster may be detached from the instrument panel main body.
In order to solve this problem, for example, a locking structure disclosed in Patent Document 1 may be provided between the meter cluster and the instrument panel main body.
In the locking structure of Patent Document 1, an insertion guide 22 having a rectangular cross section extends from the back side of the finisher 3 attached to the vehicle body side panel 1. The distal end portion of the insertion guide 22 is provided with two-stage stopper portions 26 and 27 that are displaced by 90 degrees in the circumferential direction, and the insertion guide 22 is inserted into the rectangular guide hole 23 of the vehicle body side panel 1. . The vertical and horizontal dimensions of the guide hole 23 are both larger than the dimensions of the insertion guide 22, but the horizontal dimension of the guide hole 23 is smaller than the horizontal dimension including the stopper portion, so that the finisher 3 is detached. Can be prevented.

Japanese Patent No. 4108494

The locking structure of Patent Document 1 is a structure that prevents the finisher from being detached by the two-stage stopper portion being caught in the guide hole. For this reason, if the deformation of the guide hole is large, both stopper portions are detached from the guide hole.
The stopper is provided for the purpose of preventing finishers attached to both sides of the center console at the center of the vehicle from being detached due to impact load. ) Is not considered.
Therefore, even if the locking structure is applied to a meter cluster that moves to the inside of the vehicle at the time of a side collision, the effect of preventing the separation of the meter cluster from the instrument panel body cannot be sufficiently obtained.
The present invention has been made in view of the above circumstances, and its purpose is that the instrument panel body is greatly deformed or the meter cluster moves to the inside of the vehicle due to input to the side of the vehicle. However, it is in the point of providing the attachment structure of the meter cluster which can prevent detachment | desorption of the meter cluster from an instrument panel main body reliably.

The feature of the present invention is that
A meter cluster is attached to the instrument panel body on the front side of the driver's seat through the locking means,
The locking means is a meter cluster mounting structure comprising a locking claw provided in one of the instrument panel main body and the meter cluster, and a locking hole provided in the other,
Desorption prevention means for preventing the meter cluster from detaching from the instrument panel main body at the time of input to the vehicle side part is provided,
The detachment prevention means includes a detachment prevention hole provided in one of the instrument panel body and the meter cluster, and a detachment prevention piece provided in the other and inserted into the detachment prevention hole. ,
The detachment preventing piece includes a U-shaped locking groove that opens toward the left and right center of the vehicle,
When the meter cluster is moved in the vehicle width direction with respect to the instrument panel body by the input to the vehicle side portion, the locking groove of the detachment preventing piece is locked to the peripheral edge of the detachment preventing hole. (Claim 1). According to this configuration, the following effects can be achieved.

When the meter cluster moves in the vehicle width direction with respect to the instrument panel main body by the input to the vehicle side portion, the locking groove of the detachment preventing piece is locked to the peripheral edge portion of the detachment preventing hole.
Since the locking groove is formed in a U shape that opens toward the left and right center of the vehicle, even when the deformation of the separation preventing hole is large, it is difficult to come off from the peripheral edge of the separation preventing hole. Therefore, the detachment from the detachment prevention hole of the detachment prevention piece can be reliably prevented.
More specifically, as shown in FIG. 3 as an example, when a collision occurs in the vehicle side portion 50 on the driver's seat side, the location where the meter cluster 3 is disposed is close to the location where the collision occurred, so Compared with the case where there is a collision in the vehicle side portion 51, a large force is applied to the meter cluster 3 in the direction toward the vehicle inner side (right and left center side of the vehicle). In FIG. 3, F1 and F2 are magnitudes and directions of the force applied to the meter cluster 3 when there is an input to the vehicle side portion 50 on the driver seat side, and F3 and F4 are input to the vehicle side portion 51 on the passenger seat side. This is the magnitude and direction of the force applied to the meter cluster 3 when As a result, it is conceivable that the locking claw is detached from the locking hole and the meter cluster is detached from the instrument panel body.
However, according to the above-described configuration of the present invention, the locking groove is formed in a U-shape that opens toward the left and right center of the vehicle. Even if it tries to move to the inside of the vehicle, the locking groove immediately locks to the peripheral edge of the detachment prevention hole. Therefore, detachment of the meter cluster from the instrument panel main body can be reliably prevented. (Claim 1)

In the present invention,
The locking claw comprises a claw body provided on either the instrument panel body or the meter cluster, and a claw portion protruding upward or downward from the claw body,
A claw portion that engages with a peripheral edge portion of the detachment prevention hole at a normal time when there is no input on the vehicle side portion protrudes upward or downward from a base end portion of the detachment prevention piece,
When the protruding amount in the vertical direction of the claw portion of the separation preventing piece is set longer than the protruding amount in the vertical direction of the claw portion of the locking claw, the following effect can be obtained. (Claim 2)

Since the protruding amount in the vertical direction of the claw portion of the separation preventing piece is set to be longer than the protruding amount in the vertical direction of the claw portion of the locking claw, the claw portion of the locking claw is set to the periphery of the locking hole. The claw portion of the detachment preventing piece can be locked to the peripheral edge portion of the detachment preventing hole more firmly than the structure engaged with the portion. Thereby, the nail | claw part of a removal prevention piece can be made hard to remove | deviate from a removal prevention hole.
In addition, when there is input on the side of the vehicle, if the meter cluster moves vigorously in the vehicle width direction with respect to the instrument panel body, the detachment prevention piece may break from the locking groove side, or the locking groove may It is conceivable that the detachment preventing hole may come off without being locked to the peripheral edge.
However, according to the above configuration of the present invention, since the claw portion of the detachment preventing piece projects from the base end portion of the detachment preventing piece, the locking groove engages with the peripheral portion of the detachment preventing hole. Before, the moment of detachment can be reduced with a single cushion at the claw portion of the detachment prevention piece, and as a result, the engagement groove can be reliably engaged with the peripheral portion of the detachment prevention hole. (Claim 2)

In the present invention,
The detachment prevention hole is composed of an upper wide portion and a lower narrow portion that are in communication with each other,
The detachment prevention piece is inserted through the wide part,
The thickness of the base end portion of the detachment preventing piece and the length of the wide portion in the vertical direction are set substantially the same,
The claw portion of the detachment preventing piece protrudes upward from the base end portion of the detachment preventing piece and is configured to be elastically deformed downward with respect to the surrounding detachment preventing piece portion,
As the detachment preventing piece is inserted into the wide portion, the claw portion of the detachment preventing piece is elastically deformed downward while being pressed by the peripheral edge on the upper side of the wide portion, and enters the narrow portion. When it enters and passes through the narrow portion and elastically recovers upward, the following effects can be obtained. (Claim 3)

When the detachment preventing piece is inserted into the detachment preventing hole, the tip of the detachment preventing piece is placed on the upper surface of the both sides of the narrow portion and pushed into the wide portion. Thereby, a meter cluster can be smoothly assembled | attached to an instrument panel main body. As a result, the detachment preventing piece can be easily positioned with respect to the detachment preventing hole, and the assembling property can be improved.
Further, since the thickness of the base end portion of the detachment preventing piece and the length of the wide portion in the vertical direction are set to be substantially the same, the vertical movement of the detachment preventing piece is restricted by the wide portion. Can suppress the rattling of the meter cluster. Furthermore, it is possible to prevent a step from occurring at the parting portions of the design surfaces of the meter cluster and the instrument panel, and the appearance can be improved.
If the detachment prevention hole is composed only of the wide portion, when the detachment prevention piece is inserted through the wide portion, the claw portion of the detachment prevention piece cannot be inserted by being caught by the peripheral edge of the wide portion. However, according to the above-described configuration of the present invention, since the narrow portion that communicates with the wide portion is provided, the detachment preventing piece can be smoothly inserted into the wide portion. That is, as the detachment preventing piece is inserted into the wide portion, the claw portion of the detachment preventing piece is elastically deformed downward while being pressed by the upper peripheral edge of the wide portion, and enters the narrow portion. It passes through the narrow part and elastically recovers upward. Thereby, the nail | claw part of a removal prevention piece latches on the peripheral part of the upper side of a wide part. (Claim 3)

In the present invention,

If the anti-detachment piece is formed in a trapezoidal shape as seen from the top and bottom, the following action can be achieved. (Claim 4)

Since the width of the wide portion of the detachment prevention hole and the width of the base end portion of the detachment prevention piece are set to be substantially the same, the movement of the detachment prevention piece from side to side is restricted by the detachment prevention hole. be able to. As a result, it is possible to suppress rattling on the left and right of the meter cluster when the meter cluster is assembled to the instrument panel body.
In addition, since the detachment prevention piece is formed in a trapezoidal shape as seen from the top and bottom, the detachment prevention piece can be easily inserted into the wide part, and the assembling workability can be improved. Can do. (Claim 4)

In the present invention,
The length between the bottom surface of the locking groove of the separation preventing piece and the outer surface of the separation preventing piece in the depth direction of the locking groove is set to be shorter than the width of the narrow portion. The following actions can be achieved. (Claim 5)

  When the locking claw of the meter cluster is removed from the locking hole of the instrument panel body, the locking groove of the detachment prevention piece falls into the narrow part of the detachment prevention hole, and further the locking groove is detached. It can be locked to the peripheral edge of the narrow part of the prevention hole. Therefore, the left and right movement of the detachment preventing piece can be restricted while the locking groove is locked to the peripheral edge portion, and the meter cluster can be made difficult to detach from the instrument panel body. (Claim 5)

In the present invention,
When the separation preventing piece is formed in the meter cluster and the separation preventing hole is formed in the instrument panel body, the following operation can be achieved. (Claim 6)

There are two types of vehicles, right-hand drive specifications and left-hand drive specifications, and the parts used depend on the destination. Although there are differences in the shape of details depending on the specifications of the meter cluster, the appearance is almost the same, so when both specifications are combined on the same assembly line, the meter cluster may be mistaken, which deteriorates workability. It is a factor.
The locking groove provided in the meter cluster has a shape that opens to the inside of the vehicle (the left and right center side of the vehicle) in both the right and left handle meter clusters. Therefore, even if the appearance of the meter cluster is almost the same, it is possible to distinguish between the right handle specification and the left handle specification at a glance according to the opening direction of the locking groove (if there is an opening on the left side, the right handle specification If there is an opening on the right side, it is a left handle specification).
As a result, it is possible to prevent components from being mistaken or misassembled during assembly, and to improve the assembly workability. (Claim 6)

According to the present invention,
Even if the instrument panel body is greatly deformed or the meter cluster moves to the inside of the vehicle due to input to the side of the vehicle, the detachment of the meter cluster from the instrument panel body is reliably prevented. It was possible to provide a mounting structure of the meter cluster that can be.

The panel body 2 and the meter cluster 3 are provided.

  The detachment prevention means 20 includes a detachment prevention hole 21 provided in the front end portion of the upper wall 4 of the instrument panel main body 2 and a front end portion of the upper surface portion 14 of the meter cluster 3 (the end portion on the vehicle front side Fr, Hereinafter, the same is provided), and a detachment prevention piece 22 inserted into the detachment prevention hole 21 is provided.

[Structure of Desorption Prevention Hole 21 of Desorption Prevention Means 20]
As shown in FIGS. 4 and 8 to 10, the detachment prevention hole 21 is formed at the front end portion of the mounting flange 7 provided in the upper wall 4 of the instrument panel main body 2. The detachment prevention hole 21 includes an upper wide portion 21J and a lower narrow portion 21K that are connected to each other vertically. The detachment prevention piece 22 is inserted into the wide portion 21J of the detachment prevention hole 21.

  Each of the wide portion 21J and the narrow portion 21K is formed in a rectangular shape that is long horizontally, and the centers in the width direction of the wide portion 21J and the narrow portion 21K coincide. Convex portions 24 projecting to the vehicle rear side Rr are formed on both outer sides in the width direction of the narrow portion 21K. The upper surface of the convex portion 24 is configured to be a guide surface 24J that is inclined so as to be positioned higher toward the vehicle front side Fr and guides the detachment preventing piece 22 inserted into the wide portion 21J to the vehicle front side Fr. (See FIG. 10).

[Structure of Desorption Prevention Piece 22 of Desorption Prevention Means 20]
As shown in FIGS. 5, 6, 7 (a) and 7 (b), the detachment preventing piece 22 protrudes from the front end portion of the upper surface portion 14 of the meter cluster 3 to the vehicle front side Fr, and is viewed from above and below. It is formed in a trapezoidal shape. Moreover, the detachment preventing piece 22 includes a U-shaped locking groove 25 that opens toward the left and right center of the vehicle in the front half. As shown in FIG. 7B, the inner peripheral surface 25M on the vehicle front side Fr of the locking groove 25 is inclined so as to be positioned on the vehicle front side Fr toward the upper side so that the die can be easily removed in the molding process. doing.

  Then, when the meter cluster 3 is moved inward in the vehicle width direction (to the left and right center side of the vehicle) with respect to the instrument panel body 2 by the input to the vehicle side portion, the locking groove 25 of the detachment preventing piece 22 is detached. The prevention hole 21 is configured to be engaged with the peripheral portion (the side edge portion 21J1 (see FIG. 9) of the wide portion 21J on the vehicle left-right center side).

  As shown in FIGS. 7 (a) and 7 (b), the claw portion 26 having a triangular cross section that is engaged with the peripheral edge portion of the detachment prevention hole 21 at the normal time when there is no input on the vehicle side portion is a detachment prevention piece. 22 protrudes upward from the base end 22K. The slit 45 is formed in a U-shaped continuous state on both sides of the base of the claw portion 26 and the vehicle rear side Rr, and the claw portion 26 is elastically deformed downward with respect to the surrounding separation preventing piece portion. It is configured to be possible.

  The protruding amount 26a in the vertical direction of the claw portion 26 of the detachment preventing piece 22 (the protruding amount from the upper surface of the base end portion 22K of the detachment preventing piece 22 (see FIG. 7A)) is the claw of the locking claw 9. The amount of protrusion 17a in the vertical direction of the portion 17 is set longer than the amount of protrusion from the upper surface of the claw body 16 (see FIG. 7C).

  The thickness 22a (see FIG. 7B) of the base end portion 22K of the detachment preventing piece 22 and the vertical length 21a (see FIG. 10) of the wide portion 21J of the detachment preventing hole 21 are substantially the same. The width 21b (see FIG. 9) of the wide portion 21J and the width 22b (see FIG. 6) of the base end portion 22K of the detachment preventing piece 22 are set to be substantially the same. As shown in FIGS. 7A and 7B, the base end portion 22K of the detachment prevention piece 22 located on the side of the claw portion 17 has a pair of left and right rectangular shapes along the vehicle front side Fr. The bulging portion 29 is bulged to increase the thickness 22a of the base end portion 22K.

  As the detachment prevention piece 22 is inserted into the wide portion 21J, the claw portion 26 of the detachment prevention piece 22 is pressed by the peripheral edge portion 21J2 (see FIG. 9) on the upper side of the wide portion 21J. However, it is configured to be elastically deformed downward to enter the narrow portion 21K and to be elastically restored upward through the narrow portion 21K. Thereby, the nail | claw part 26 of the removal prevention piece 22 latches to the peripheral part 21J2 above the wide part 21J. For example, if the detachment prevention hole 21 is composed only of the wide portion 21J, the claw portion 26 of the detachment prevention piece 22 is caught by the peripheral portion of the wide portion 21J when the detachment prevention piece 22 is inserted through the wide portion 21J. It cannot be inserted. However, according to the above configuration of the present invention, the narrow portion 21K communicating with the wide portion 21J is provided, so that the detachment preventing piece 22 can be smoothly inserted into the wide portion 21J as described above. Can do.

According to the configuration of the present invention,
(1) When the meter cluster 3 is moved inward in the vehicle width direction (the left and right center side of the vehicle) with respect to the instrument panel body 2 by the input to the vehicle side portion, the locking groove 25 of the removal preventing piece 22 is removed. The separation preventing hole 21 is engaged with the peripheral edge (the side edge 21J1 of the wide portion 21J on the left and right center side of the vehicle).
Since the locking groove 25 is formed in a U-shape that opens toward the left and right center of the vehicle, even when the deformation of the separation preventing hole 21 is large, it is difficult to come off from the peripheral edge of the separation preventing hole 21. . Accordingly, it is possible to reliably prevent the detachment prevention piece 22 from being detached from the detachment prevention hole 21.
More specifically, when there is a collision in the vehicle side portion on the driver's seat side, there is a collision in the vehicle side body on the passenger seat side because the location where the collision occurred is close to the position where the meter cluster 3 is arranged. As compared with the above, a large force is applied to the meter cluster 3 in the direction toward the vehicle inner side (right and left center side of the vehicle). As a result, it is conceivable that the locking claw 9 is detached from the locking hole 8 and the meter cluster 3 is detached from the instrument panel body 2. However, according to the above-described configuration of the present invention, the locking groove 25 is formed in a U shape that opens toward the left and right center of the vehicle, so that the locking claw 9 comes off the locking hole 8. Even if the meter cluster 3 tries to move to the inside of the vehicle (the left and right center side of the vehicle), the locking groove 25 immediately becomes the peripheral edge portion of the detachment prevention hole 21 (the side edge portion 21J1 on the vehicle left and right center side of the wide portion 21J). ). Therefore, the detachment of the meter cluster 3 from the instrument panel body 2 can be reliably prevented. FIG. 2 shows a state where detachment is prevented.

(2) Since the protruding amount 26a in the vertical direction of the claw portion 26 of the separation preventing piece 22 is set longer than the protruding amount 17a in the vertical direction of the claw portion 17 of the locking claw 9, the locking claw The claw portion 26 of the detachment preventing piece 22 is more firmly attached to the rim portion of the detachment prevention hole 21 (the rim portion on the upper side of the wide portion 21J) than the structure in which the nine claw portions 17 are locked to the rim portion of the locking hole 8. 21J2). Thereby, the claw part 26 of the detachment preventing piece 22 can be made difficult to be detached from the detachment preventing hole 21.
In addition, when there is an input on the vehicle side, if the meter cluster 3 moves vigorously in the vehicle width direction with respect to the instrument panel body 2, the detachment prevention piece 22 may break from the locking groove 25 side, It is conceivable that the locking groove 25 may come off without being locked to the peripheral edge of the detachment prevention hole 21. However, according to the above-described configuration of the present invention, the claw portion 26 of the detachment preventing piece 22 protrudes from the base end portion 22K of the detachment preventing piece 22, so Before engaging with the peripheral portion (the side edge portion 21J1 of the wide side portion 21J on the vehicle left and right center side), the claw portion 26 of the separation preventing piece 22 can be used to reduce the momentum of detachment. Thus, the locking groove 25 can be reliably locked to the peripheral edge of the detachment prevention hole 21.

(3) When the detachment prevention piece 22 is inserted into the detachment prevention hole 21, the tip of the detachment prevention piece 22 is placed on the guide surfaces 24J (upper surface) of the convex portions 24 on both sides of the narrow portion 21K. It is pushed into the wide portion 21J while being guided by the surface 24J (upper surface). Thereby, the meter cluster 3 can be assembled | attached to the instrument panel main body 2 smoothly. As a result, the detachment preventing piece 22 can be easily positioned with respect to the detachment preventing hole 21 and the assemblability can be improved.
In addition, since the thickness 22a of the base end portion 22K of the detachment preventing piece 22 and the vertical length 21a of the wide portion 21J are set to be substantially the same, The movement can be restricted by the wide portion 21J, and rattling of the meter cluster 3 can be suppressed. Furthermore, it is possible to prevent a step from occurring in the parting portions of the design surfaces of the meter cluster 3 and the instrument panel 1 and improve the appearance.

(4) Since the width 21b of the wide portion 21J of the detachment prevention hole 21 and the width 22b of the base end portion 22K of the detachment prevention piece 22 are set to be substantially the same, The left and right movement of the separation preventing piece 22 can be restricted. As a result, left and right rattling of the meter cluster 3 when the meter cluster 3 is assembled to the instrument panel body 2 can be suppressed.
Further, since the detachment preventing piece 22 is formed in a tapered trapezoidal shape when viewed from above and below, the detachment preventing piece 22 can be easily inserted into the wide portion 21J, and assembly workability is improved. Can be improved.

(5) There are two types of vehicles, right-hand drive specifications and left-hand drive specifications, and the parts to be used differ depending on the destination. Although there are differences in the shape of the details of the meter cluster 3 depending on the specifications, the appearance is almost the same, so when both specifications are grouped on the same assembly line, the meter cluster 3 may be mistaken, and workability may be reduced. It is one factor that makes it worse.
The locking groove 25 provided in the meter cluster 3 has a shape that opens to the inner side of the vehicle (the vehicle left and right center side) in both the right handle specification and the left handle specification meter cluster 3. Therefore, even in the case of the meter cluster 3 having substantially the same appearance, it is possible to distinguish between the right handle specification and the left handle specification at a glance according to the opening direction of the locking groove 25 (if there is an opening on the left side, Handle specification. If there is an opening on the right side, it is a left handle specification). As a result, it is possible to prevent components from being mistaken or misassembled during assembly, and to improve the assembly workability.

[Another embodiment]
(1) As shown in FIG. 6, a length 22c between the bottom surface 25T of the locking groove 25 of the detachment preventing piece 22 and the outer side surface 22S of the detachment preventing piece 22 in the depth direction of the locking groove 25. However, it may be set shorter than the width 21c of the narrow portion 21K.
According to this configuration, when the locking claw 9 of the meter cluster 3 is disengaged from the locking hole 8 of the instrument panel main body 2, the locking groove 25 of the detachment preventing piece 22 has the width of the detachment preventing hole 21. It can fall to the narrow portion 21K, and the locking groove 25 can be locked to the peripheral edge portion 21K1 of the narrow width portion 21K of the detachment preventing hole 21. Therefore, the left and right movement of the detachment preventing piece 22 can be restricted while the locking groove 25 is locked to the peripheral edge portion 21K1, and the meter cluster 3 can be made difficult to detach from the instrument panel body 2. .
(2) The locking claws 9 may be provided in the instrument panel main body 2, and the locking holes 8 may be provided in the meter cluster 3.
