Description

TECHNICAL FIELD The present invention relates to a ceiling component mounting method and a ceiling component mounting structure.

Japanese Patent Application Laid-Open No. 2002-200000 discloses a conventional mounting method for a ceiling component (hereinafter simply referred to as a mounting method). In this mounting method, the ceiling parts are mounted on the ceiling material. The ceiling material constitutes the ceiling of the passenger compartment by being fixed to the vehicle body. The ceiling material has a plate shape having a first surface and a second surface. The first side faces the passenger compartment. The second surface is located opposite the first surface. Further, the ceiling member is formed with a mounting hole penetrating from the first surface to the second surface.

The ceiling component has a component body and a case. This ceiling component is specifically an acoustic component. Further, the component body is specifically a microphone. The case is made of resin. The case has a first claw and a second claw.

In this mounting method, first of all, a preparatory step is performed. In the preparation process, ceiling materials and ceiling parts are prepared. Next, an approach process is performed. In the entering step, the case is inserted into the mounting hole from the first surface side of the ceiling material, and the first claw is positioned on the second surface side of the ceiling material.

Next, a first attachment step is performed. In the first attachment step, the case is attached to the ceiling material by engaging the first claw with the peripheral edge of the attachment hole on the second surface side. Next, a second attachment step is performed. In the second attachment step, the component body is attached to the case by engaging the component body with the second claws of the case from the second surface side. In this way, attachment of the ceiling parts to the ceiling material is completed.

JP 2009-264564 A

By the way, in order to make the first surface of the ceiling material face the passenger compartment, it is necessary to attach the ceiling material to the vehicle body with the second surface of the ceiling material facing the opposite side of the passenger compartment, that is, the vehicle body. . However, in the conventional mounting method described above, when mounting the ceiling component to the ceiling material, the case is inserted into the mounting hole from the first surface side of the ceiling material. Therefore, when the second surface faces the vehicle body, it is impossible to attach the ceiling parts to the ceiling material, or it becomes extremely difficult to attach the ceiling parts to the ceiling material. For this reason, with this mounting method, the efficiency of the work for mounting the ceiling component to the ceiling material cannot be increased. On the other hand, if the work of attaching the ceiling parts to the ceiling material is prioritized, it is necessary to turn the second surface of the ceiling material to which the ceiling parts have been attached so that the second surface faces the vehicle body, which increases the number of man-hours. For these reasons, this mounting method cannot increase the manufacturing efficiency of the vehicle, and it is difficult to reduce the manufacturing cost of the vehicle.

Further, in this mounting method, the case is mounted on the ceiling material by engaging the first claws with the periphery of the mounting hole. By the way, resin with relatively low rigidity may be used for the ceiling material. For this reason, with such a low-rigidity ceiling material, the ceiling material bends, so that the first claw cannot be preferably locked to the peripheral edge of the mounting hole. As a result, with this mounting method, it is difficult to ensure sufficient mounting strength of the ceiling component to the ceiling material, and there is a risk that the ceiling component will fall off the ceiling material.

Therefore, when a ceiling material having a low rigidity is adopted, a member having a higher rigidity than the ceiling material is provided at the peripheral edge of the mounting hole on the second surface side, and the mounting hole is connected through this member. It is conceivable to secure the attachment strength of the ceiling component to the case by locking the first claw to the peripheral edge. It is also conceivable to secure the mounting strength of the ceiling parts to the ceiling material by screwing the case to the ceiling material. However, if these operations are performed, the number of man-hours for attaching the ceiling parts to the ceiling material increases accordingly, and the efficiency of the attachment operation decreases. In this respect as well, it is difficult to reduce the cost of manufacturing vehicles.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional circumstances, and provides a method for mounting a ceiling part that can suitably prevent the ceiling part from falling off from the ceiling material while realizing a reduction in the manufacturing cost of a vehicle. The problem to be solved is to provide a method and a mounting structure for ceiling parts.

A ceiling component mounting method of the present invention is a ceiling component mounting method for mounting a ceiling component to a ceiling material that is fixed to a vehicle body and constitutes a ceiling of a vehicle compartment, and comprises:
The ceiling material has a plate shape having a first surface facing the vehicle compartment and a second surface located on the opposite side of the first surface,

In the mounting method of the present invention, the ceiling component prepared in the preparation step has the first contact portion. The first contact portion is made of an elastically deformable elastic body and fixed to the case. In this mounting method, the first contact portion is elastically deformed in the entering step, thereby causing the first contact portion to enter the mounting hole from the second surface side of the ceiling material, thereby moving the inside of the mounting hole to the second surface. Let it pass up to one side. Thus, in this mounting method, the first contact portion is positioned on the first surface side of the ceiling material, that is, on the passenger compartment side, while the case, and thus the ceiling member, is mounted on the ceiling material from the second surface side. can be done. Thus, in this mounting method, it is not necessary to insert the case into the mounting hole from the first surface side when mounting the ceiling component to the ceiling material.

As a result, since the first surface faces the passenger compartment, even if the second surface of the ceiling material faces the vehicle body, the ceiling member can be suitably attached to the ceiling material in this mounting method. be able to. Thus, according to this mounting method, the efficiency of the work for mounting the ceiling component to the ceiling material can be improved, and as a result, the manufacturing efficiency of the vehicle can be increased.

Further, in this mounting method, the first contact portion is brought into contact with the first surface and the second contact portion is brought into contact with the second surface in the installation step. By sandwiching the ceiling material between the first contact portion and the second contact portion, the ceiling component is attached to the ceiling material.

As a result, in this mounting method, even if the ceiling material has low rigidity and is easily bent, the ceiling material is held between the first contact portion and the second contact portion so that the ceiling material can be easily bent. It is possible to suitably secure the attachment strength of the ceiling parts to the. Thus, in this mounting method, in order to secure the mounting strength of the ceiling parts to the ceiling material, there is no need to separately provide a highly rigid member to the ceiling material or to screw the case to the ceiling material.

As a result, in this mounting method, the efficiency of the work for mounting the ceiling member to the ceiling material can be sufficiently increased.

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

A vehicle 1 shown in FIG. 1 has a vehicle body 3 , a ceiling material 5 , and a microphone device 7 . The vehicle 1 is specifically a passenger car. In the vehicle 1, the microphone device 7 is attached to the ceiling material 5 by the attachment structure 9 of the embodiment. The microphone device 7 is an example of the "ceiling part" in the present invention.

In this embodiment, the vertical direction and the front-rear direction of the vehicle body 3 and the microphone device 7 are defined by solid arrows shown in FIG. 2 defines the vertical direction and the front-rear direction of the vehicle body 3 and the microphone device 7, corresponding to FIG. . 3 and subsequent drawings, the vertical direction, the front-rear direction, and the horizontal direction of the vehicle body 3 and the microphone device 7 are defined corresponding to FIGS. These up-down direction, front-rear direction and left-right direction are orthogonal to each other.

As shown in FIG. 1, the vehicle body 3 has a roof panel 31 extending in the front-rear direction and the left-right direction, as well as an electric cable 33, a battery (not shown), and a control device (not shown). have. The roof panel 31 is made of a metal plate. The energization cable 33 is energized and connected to the battery and the control device. Further, the vehicle body 3 is formed with a vehicle room CR. Although not shown, the vehicle body 3 is provided with a power unit and the like necessary for running the vehicle 1 .

The ceiling material 5 is made of resin and has a plate shape extending in the front-rear direction and the left-right direction. The ceiling material 5 is fixed to the vehicle body 3 and arranged below the roof panel 31 . Thereby, the ceiling material 5 constitutes the ceiling of the passenger compartment CR. A mounting space 11 is formed between the ceiling material 5 and the roof panel 31 . In the mounting space 11, in addition to the conducting cable 33, the microphone device 7 is arranged.

Here, in the vehicle 1, the ceiling material 5 is made of resin having relatively low rigidity. For this reason, the ceiling material 5 is likely to bend when a load is applied from the vehicle room CR side or the mounting space 11 side. In addition, the material of the ceiling material 5 can be appropriately designed, and the ceiling material 5 may be formed of a resin having a high rigidity that is difficult to bend.

The ceiling material 5 has a first surface 51 and a second surface 53 . The first surface 51 faces the compartment CR and constitutes the surface of the ceiling material 5 . The second surface 53 is located on the opposite side of the first surface 51 and faces the roof panel 31 and the mounting space 11 . The second surface 53 constitutes the back surface of the ceiling material 5 .

Further, the ceiling material 5 is formed with mounting holes 55 . The mounting hole 55 is formed in a substantially rectangular shape and penetrates the ceiling material 5 from the first surface 51 to the second surface 53 . Thus, the attachment hole 55 communicates the vehicle room CR and the attachment space 11 . The length of the inner diameter of the attachment hole 55 is set to the first length L1.

Further, in the ceiling material 5, the plate thickness around the attachment hole 55 is the second length L2. Further, in the ceiling material 5, the plate thickness becomes longer than the second length L2 as the distance from the mounting hole 55 increases. Here, the second length L2 is shorter than the first length L1. The thickness of the ceiling material 5 may be constant at the second length L2.

The microphone device 7 has a microphone body 71 , a case 73 and a bezel 75 . The microphone main body 71 is an example of the "component main body" in the present invention. Also, the bezel 75 is an example of the "first contact portion" in the present invention.

Although not shown in detail, the microphone main body 71 has a housing, a diaphragm and a control board provided inside the housing, and a connector section 71a. An electric cable 33 is connected to the connector portion 71a. The microphone main body 71 is supplied with power from the battery through the power supply cable 33, and is controlled by the control device, so that it can convert voice mainly generated in the passenger compartment CR into an electric signal. In addition, in FIG. 1 and the like, the microphone main body 71 is schematically illustrated in order to facilitate the explanation.

The case 73 shown in FIG. 2 is made of ABS resin and has relatively high rigidity.
The case 73 has a base portion 73a, a first vertical wall 73b, a second vertical wall 73c, a support wall 73d, a front contact piece 73e, and a rear contact piece 73f. The front side contact piece 73e and the rear side contact piece 73f are examples of the "second contact portion" in the present invention. In FIG. 2, illustration of the microphone main body 71 is omitted for ease of explanation.

The base 73 a is located at the lower end of the case 73 . The base portion 73a has a substantially rectangular shape extending in the front-rear direction and the left-right direction. As shown in FIG. 1, the microphone main body 71 is fixed to the upper portion of the base portion 73a, that is, to the attachment space 11 side of the base portion 73a. Further, as shown in FIG. 2, a plurality of transmission holes 730 for transmitting sound to the microphone main body 71 are formed in the base portion 73a. Each transmission hole 730 extends vertically through the base portion 73a. The number and shape of each transmission hole 730 can be appropriately designed.

As shown in FIG. 2, the first vertical wall 73b is located in the front part of the case 73. As shown in FIG. On the other hand, the second standing wall 73c is positioned at the rear of the case 73. As shown in FIG. The first standing wall 73b and the second standing wall 73c are each integral with the base portion 73a and linearly extend upward from the case 73. As shown in FIG.

73 d of support walls are arrange|positioned in the case 73 between the 1st standing wall 73b and the 2nd standing wall 73c. The support wall 73d is also integrated with the base portion 73a and linearly extends upward from the case 73 . The support wall 73d can support the microphone body 71 fixed to the base 73a.

The front contact piece 73e is formed integrally with the first standing wall 73b and extends forward from the first standing wall 73b in a rectangular plate shape. The rear contact piece 73f is integrally formed with the second standing wall 73c and extends rearward from the second standing wall 73c in a rectangular plate shape. Here, the front contact piece 73e extends forward longer than the bezel 75, and the rear contact piece 73f extends rearward longer than the bezel 75. As shown in FIG.

Further, the plate thicknesses of the front side contact piece 73e and the rear side contact piece 73f are designed according to the weight of the microphone device 7 and the like. The shape of the front side contact piece 73e and the rear side contact piece 73f is not limited to a rectangular plate shape, and can be designed as appropriate. Further, for example, the formation of the rear side contact piece 73f may be omitted, and the front side contact piece 73e may extend annularly in the circumferential direction of the case 73. As shown in FIG.

The bezel 75 is made of synthetic rubber as an elastic body and is elastically deformable. Moreover, since the bezel 75 is made of synthetic rubber, the rigidity of the bezel 75 is lower than that of the case 73 . The bezel 75 has a rectangular annular shape and is fixed to the lower portion of the case 73 . Thereby, the bezel 75 covers the base portion 73a in the circumferential direction from the outside of the base portion 73a.

Here, in forming this bezel 75, a previously formed case 73 is prepared. Then, while housing the case 73 in a molding die (not shown) for forming the bezel 75,
Synthetic rubber forming the bezel 75 is injection-molded to the lower portion of the case 73, that is, the portion around the base portion 73a. Thus, the bezel 75 is integrally formed with the case 73 and fixed to the case 73 . The bezel 75 may be fixed to the case 73 by forming the case 73 and the bezel 75 separately and bonding the bezel around the base portion 73a. Also, the bezel 75 may be made of an elastic material other than synthetic rubber as long as it is elastically deformable.

2 and 3, the length of the outer diameter of the bezel 75 is the third length L3. This third length L3 is longer than the first length L1 that is the length of the inner diameter of the mounting hole 55 . That is, the bezel 75 has a rectangular annular shape that is larger than the mounting hole 55 . Further, as shown in FIG. 3, both the vertical interval between the bezel 75 and the front contact piece 73e and the vertical interval between the bezel 75 and the rear contact piece 73f are the second length. L2. That is, the vertical distance between the front contact piece 73e and the rear contact piece 73f and the bezel 75 is equal to the plate thickness of the ceiling member 5 around the mounting hole 55. As shown in FIG.

The mounting structure 9 is composed of the ceiling material 5 , the microphone device 7 , and the power cable 33 . In this mounting structure 9, the work of mounting the microphone device 7 to the ceiling material 5 is performed by the mounting method of the embodiment described below.

In this mounting method, first of all, a preparatory step is performed. As shown in FIG. 3, in the preparation process, the ceiling material 5 and the microphone device 7 are prepared. Here, the ceiling material 5 prepared in the preparation process is in a state before being fixed to the vehicle body 3 . In addition, mounting holes 55 are already formed in the ceiling member 5 . In the preparatory step, the ceiling material 5 is placed so that the first surface 51 faces downward and the second surface 53 faces upward. This completes the preparation process. In the microphone device 7 prepared in the preparation step, the microphone body 71 and the bezel 75 are fixed to the case 73 .

Next, an approaching process is performed. In performing the entering step, the microphone device 7 is positioned above the ceiling material 5, and the case 73 and the bezel 75 are opposed to the second surface 53 of the ceiling material 5 in the vertical direction. Then, in this state, the microphone device 7 is moved downward as indicated by the white arrow in FIG.

Here, the length of the outer diameter of the bezel 75 is the second length L2, which is longer than the first length L1, which is the length of the inner diameter of the mounting hole 55. As shown in FIG. However, the bezel 75 is made of synthetic rubber and is elastically deformable. Therefore, as shown in FIG. 4, when the base portion 73a of the case 73 and the bezel 75 are inserted into the mounting hole 55, the bezel 75 is elastically deformed so as to bend upward while contacting the inner wall of the mounting hole 55. do. As a result, the outer diameter of the bezel 75 is shorter than the inner diameter of the mounting hole 55, so that the base 73a of the case 73 and the bezel 75 are positioned on the first surface 51 side as indicated by the white arrows in FIG. It can move downward in the mounting hole 55 toward the outside. Then, when the base portion 73a and the bezel 75 pass through the mounting hole 55 to the first surface 51 side, the entering step is completed.

Further, since the base portion 73 a and the bezel 75 pass through the mounting hole 55 to the first surface 51 side in this way, the bezel 75 does not contact the inner wall of the mounting hole 55 . Therefore, the bezel 75 is restored to the state before contacting the inner wall of the mounting hole 55, that is, the original state in which the outer diameter is the second length L2.

Next, an attachment process is performed. In the mounting step, as shown in FIG. 5 , the bezel 75 that has passed through the mounting hole 55 to the side of the first surface 51 is brought into contact with the first surface 51 . At this time, since the outer diameter of the bezel 75 is the second length L2, the attachment hole 55 is covered with the bezel 75 from below when the bezel 75 comes into contact with the first surface 51 .

Further, in the mounting step, the front side contact piece 73e and the rear side contact piece 73f are brought into contact with the second surface 53, respectively. Here, in the microphone device 7, the vertical distance between the front side contact piece 73e and the rear side contact piece 73f and the bezel 75 is the second length L2. It is equal to the thickness of the surrounding plate. Therefore, in the microphone device 7, when the base portion 73a and the bezel 75 pass through the mounting hole 55 to the first surface 51 side and the bezel 75 contacts the first surface 51, the front contact piece 73e and the front contact piece 73e The rear side contact piece 73f comes into contact with the second surface 53. As shown in FIG.

In this manner, the bezel 75 contacts the first surface 51, and the front contact piece 73e and the rear contact piece 73f contact the second surface 53, so that the microphone device 7 has the bezel 75 and the front contact piece. The ceiling material 5 is vertically sandwiched between the side contact piece 73e and the rear side contact piece 73f. As a result, the case 73 and the microphone device 7 are attached to the ceiling material 5, and the attachment process is completed.

Next, a connection process is performed. In the connection step, as shown in FIG. 6, the power cable 33 is connected to the connector portion 71a of the microphone body 71. As shown in FIG. As a result, the microphone main body 71 and the power supply cable 33 are electrically connected. Thus, the work of attaching the microphone device 7 to the ceiling material 5 is completed.

At the same time when the connection process is performed, an assembly process for fixing the ceiling material 5 to which the microphone device 7 is attached to the vehicle body 3 is performed. At this time, as shown in FIG. 1 , the ceiling material 5 is fixed to the vehicle body 3 with the second surface 53 facing upward, that is, toward the roof panel 31 . In this way, the ceiling material 5 is fixed to the vehicle body 3 and constitutes the ceiling of the vehicle compartment CR, and the microphone device 7 is arranged in the mounting space 11 to face the ceiling of the vehicle compartment CR. Note that the connecting process and the assembling process may be performed separately.

As described above, in this mounting method, the base portion 73a of the case 73 and the bezel 75 are caused to enter the mounting hole 55 from the second surface 53 side of the ceiling material 5 by elastically deforming the bezel 75 in the entering step. The inside of the attachment hole 55 is made to pass to the 1st surface 51 side. Thus, in this mounting method, the case 73, and thus the microphone device 7, is mounted on the ceiling material 5 from the second surface 53 side, while the bezel 75 is mounted on the first surface 51 side of the ceiling material 5, that is, on the compartment CR side. It is possible to position Thus, in this mounting method, it is not necessary to insert the case 73 into the mounting hole 55 from the first surface 51 side when mounting the microphone device 7 to the ceiling material 5 .

As a result, according to this mounting method, while the second surface 53 of the ceiling material 5 faces upward, the work of mounting the microphone device 7 to the ceiling material 5 and the work of connecting the current-carrying cable 33 to the microphone main body 71 are carried out. Further, the operation of fixing the ceiling material 5 to the vehicle body 3 can be performed in series. Thus, according to this mounting method, the efficiency of the work of mounting the microphone device 7 on the ceiling material 5 can be increased, and as a result, the manufacturing efficiency of the vehicle 1 can be increased.

In addition, in this mounting method, the bezel 75 is brought into contact with the first surface 51 and the front side contact piece 73e and the rear side contact piece 73f are brought into contact with the second surface 53 in the mounting process. Here, the bezel 75 passes through the mounting hole 55 to the side of the first surface 51 and reaches the side of the first surface 51 , thereby returning from the elastically deformed state to the original state and coming into contact with the first surface 51 . . In the microphone device 7 , the vertical distance between the front contact piece 73 e and the rear contact piece 73 f and the bezel 75 is equal to the plate thickness of the ceiling material 5 around the mounting hole 55 . Therefore, when the base portion 73a and the bezel 75 are inserted into the mounting hole 55 from the second surface 53 side of the ceiling material 5 and the bezel 75 contacts the first surface 51, the front side contact piece 73e and the rear side contact piece 73e and the rear side contact piece 73e are formed. The contact pieces 73f are in contact with the second surface 53 respectively.

Thus, in this mounting method, if the base portion 73a and the bezel 75 are inserted into the mounting hole 55 from the side of the second surface 53, the bezel 75 can be brought into contact with the first surface 51 without any separate work. In addition, the front side contact piece 73e and the rear side contact piece 73f can be brought into contact with the second surface 53, respectively. The case 73 and the microphone device 7 are attached to the ceiling material 5 by vertically holding the ceiling material 5 between the bezel 75 and the front contact piece 73e and the rear contact piece 73f. .

Here, the ceiling material 5 is made of resin having low rigidity, and is easily bent. In this regard, in this mounting method, even if the ceiling material 5 has low rigidity and is easily bent, the bezel 75, the front side contact piece 73e, and the rear side contact piece 73f are attached to the ceiling material. 5, the attachment strength of the microphone device 7 to the ceiling material 5 is suitably ensured. As described above, in this mounting method, in securing the mounting strength of the microphone device 7 to the ceiling material 5 , a highly rigid member is separately provided on the second surface 53 of the ceiling material 5 or the case 73 is attached to the ceiling material 5 . No need to screw.

Therefore, according to the mounting method and the mounting structure 9 of the embodiment, it is possible to suitably prevent the microphone device 7 from falling off from the ceiling material 5 while reducing the manufacturing cost of the vehicle 1 .

In particular, in this mounting method, the connection step, that is, the work of connecting the current-carrying cable 33 to the connector portion 71 a of the microphone body 71 is performed on the second surface 53 side. In this respect, as described above, in this mounting method, the work of mounting the microphone device 7 to the ceiling material 5 is performed from the second surface 53 side, so that the connection process can also be suitably performed.

Moreover, in this mounting method, the mounting hole 55 is covered with the bezel 75 when the bezel 75 comes into contact with the first surface 51 . As a result, the mounting hole 55 is not visible from the compartment CR side, so that this mounting method can also improve the appearance of the compartment CR.

Although the present invention has been described above with reference to the embodiments, it goes without saying that the present invention is not limited to the above embodiments, and can be modified and applied without departing from the scope of the invention.

For example, in the mounting method of the embodiment, the connecting process is performed after the mounting process, but the connecting process is not limited to this, and the connecting process may be performed before the approaching process and the mounting process.

In the mounting process, the ceiling material 5 is vertically sandwiched between the bezel 75 and the front contact piece 73e and the rear contact piece 73f.
