[0003] [Patent Document 1] JP 2004-336971 A Summary of the Invention [Problem to be solved by the invention]

[0004] According to the above wiring structure, the harness, which is the object to be attached, is attached to the cover, which is the object to be attached, and then the cover, which is the object to be attached, is attached to the front end panel, which is the object to be attached. In such a structure in which the harness and the cover are attached to different objects, the installation operation of the harness and the cover is likely to be complicated. In addition, the space required for installing the harness and the cover is likely to be large, which is a problem in that the wiring structure of the harness becomes large. Such a problem can occur not only in the wiring structure of the harness, but also in an assembly structure in which a similar string-like member is assembled to the harness.

[0005] The present invention has been made in consideration of the above problems, and aims to provide a technique that is effective in reducing the size of an assembly structure for assembling a string-shaped member to a vehicle. [Means for solving the problem]

[0006] One aspect of the present invention is An assembly structure for assembling a string-shaped member to a vehicle, a bracket member provided on the vehicle so as to be able to hold the string-shaped member; A cover member attached to the bracket member; Equipped with a through hole for guiding the string-shaped member to a vehicle interior side is provided in a ceiling of the vehicle, The cover member is configured to cover both the string-like member and the bracket member when attached to the bracket member holding the string-like member. R, the bracket member includes a pair of engaging claw portions that extend to a vehicle interior side through the through hole in the ceiling and face each other across an accommodation space that accommodates the string-like member, The pair of engaging claw portions are provided with a pair of flexible pieces that form a push-in opening that communicates with the storage space, and the pair of flexible pieces are configured to elastically deform and temporarily expand the push-in opening upon receiving a load in a push-in direction when the string-like member is pushed into the storage space through the push-in opening, Each of the pair of engaging claw portions is provided with a protruding portion that protrudes outward from an outer surface opposite to an inner wall surface that defines the storage space, and the cover member is provided with an engaging piece that engages with the protruding portion by movement in an attachment direction relative to the bracket member, and is configured so that the engaging piece overcomes and hooks onto the protruding portion by elastic deformation, The cover member is configured to close the through hole in the ceiling in an attached state in which the engagement pieces are engaged with the protrusions provided on the pair of engagement claw portions of the bracket member. , assembly structure, is located. Effect of the Invention

[0007] In the assembly structure of the above aspect, the string-like member is held by a bracket member provided on the vehicle. At this time, the bracket member is an attachment target to which the string-like member is attached. The bracket member also is an attachment target to which the cover member is attached. In other words, the bracket member is an attachment target for both the string-like member and the cover member.

[0008] If the bracket member is used as the attachment target for both the string-like member and the cover member, the space required for attaching the string-like member and the cover member can be kept small, which is effective in miniaturizing the assembly structure compared to when the attachment target of the string-like member and the attachment target of the cover member are different separate members. When the cover member is attached to the bracket member holding the string-like member, both the string-like member and the bracket member are covered by this cover member.

[0009] As described above, according to the above-mentioned aspect, it is possible to provide a technique that is effective in reducing the size of an assembly structure for assembling a string-shaped member to a vehicle. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Preferred embodiments of the above aspects are described below.

[0012] In the assembly structure of the above aspect, the bracket member has a pair of engaging claw portions facing each other across a storage space that houses the string-like member, and the pair of engaging claw portions are provided with a pair of flexible pieces that form a push-in opening that communicates with the storage space, and it is preferable that the pair of flexible pieces are configured to elastically deform upon receiving a load in the pushing direction when the string-like member is pushed into the storage space through the push-in opening, thereby temporarily expanding the push-in opening.

[0013] According to this assembly structure, it is possible to hold the string-like member by utilizing a simple structure in which the string-like member is pushed into the accommodation space through a push-in opening between a pair of flexible pieces of the bracket member.

[0014] In the assembly structure of the above aspect, each of the pair of engaging claw portions of the bracket member is provided with a protrusion formed by protruding outward on the outer surface opposite the inner wall surface that defines the storage space, and the cover member is preferably provided with an engaging piece that engages with the protrusion upon movement in the mounting direction relative to the bracket member, and is configured so that the engaging piece overcomes the protrusion and becomes hooked upon by elastic deformation.

[0015] According to this assembly structure, it is possible to attach the cover member to the bracket member by utilizing a simple structure in which the engagement pieces of the cover member are fitted into the protrusions provided on each of a pair of engagement claws of the bracket member.

[0016] In the assembly structure of the above aspect, it is preferable that the pushing direction of the string-like member and the mounting direction of the cover member are the same direction.

[0017] According to this assembly structure, by matching the pushing direction in which the string-shaped member is pushed into the storage space of the bracket member with the installation direction in which the cover member is attached to the bracket member, the operation of the cover member and the bracket member is unified and simplified, thereby improving the overall workability involved in assembling the string-shaped member.

[0018] Hereinafter, a specific embodiment of a vehicle mounting structure provided in a vehicle will be described with reference to the drawings.

[0019] In the drawings for explaining this assembly structure, unless otherwise specified, the upper side of the vehicle is indicated by an arrow UP, and the inside of the vehicle is indicated by an arrow IN. In addition, the first direction of the assembly structure is indicated by an arrow X, and the second direction perpendicular to the first direction is indicated by an arrow Y.

[0020] (Embodiment 1) As shown in FIG. 1, an assembly structure 10 of the first embodiment is a structure for assembling a wire harness W to a vehicle 1.

[0021] The wire harness (hereinafter simply referred to as "harness") W is an electrical connection part that electrically connects the camera device 11, which is an in-vehicle device, and the control unit 20. This harness W is used to supply power to the camera device 11 and to transmit control signals and detection information between the camera device 11. This harness W is a string-like or linear member whose cross-sectional diameter is roughly uniform and which has flexibility to bend freely.

[0022] The camera device 11 is provided on the vehicle interior side in the upper central area (near the rearview mirror) of the windshield 2 and ceiling 3 of the vehicle 1. This camera device 11 is equipped with a collision avoidance support camera module 12 that captures images of the outside of the vehicle to assist in collision avoidance of the vehicle 1. The camera module 12 has a known structure, and detailed structure description will be omitted, but it is equipped with multiple elements such as a lens for capturing images of the outside of the vehicle and a camera board. Image information captured by the camera module 12 is transmitted to the control unit 20 via a harness W.

[0023] In addition to the camera module 12, the camera device 11 includes a camera cover 13 that covers the camera module 12, and a harness cover 14 that covers the harness W. Both the camera cover 13 and the harness cover 14 are configured as resin molded products made of a resin material. The camera cover 13 is a resin part separate from the harness cover 14.

[0024] 2, camera cover 13 has storage space 13a for storing camera module 12, and is configured so that storage space 13a is open on the windshield 2 side. Therefore, when camera cover 13 is attached to windshield 2, camera module 12 is surrounded by camera cover 13 except for the windshield 2 side.

[0025] 3, the ceiling 3 is provided with a through hole 4 for guiding the harness W to the vehicle interior, and a bracket member 5 extending from the through hole 4 to the vehicle interior. The harness W guided to the vehicle interior through the through hole 4 in the ceiling 3 is introduced into the accommodation space 13a through an introduction port 13b provided in the camera cover 13. The harness W is electrically connected to the camera module 12 in the accommodation space 13a.

[0026] The detailed structure of the bracket member 5 will be described later, but it is a holding member provided on the vehicle 1 so as to be able to hold the harness W, and is configured to be used to attach the harness cover 14, which is a cover member. In other words, the bracket member 5 has both the function of holding the harness W and the function of attaching the harness cover 14. The bracket member 5 is a resin molded product made of a resin material, and is fixed to a ceiling panel (not shown) that constitutes the vehicle body. The bracket member 5 and the harness cover 14 constitute an assembly structure 10.

[0027] The harness cover 14 has an accommodation space 14a for accommodating the harness W and the bracket member 5, and is configured so that the accommodation space 14a is open on the side of the through hole 4. The harness cover 14 is attached to the bracket member 5. When the harness cover 14 is attached to the bracket member 5, the through hole 4 in the ceiling 3 is blocked by the harness cover 14.

[0028] At this time, the lead-out port 14b provided in the harness cover 14 is configured to communicate with the lead-in port 13b of the camera cover 13. Therefore, the harness W led to the vehicle interior side through the through-hole 4 in the ceiling 3 is exposed inside the vehicle interior when the harness cover 14 is removed from the bracket member 5, whereas the harness cover 14 is covered from the vehicle interior side when the harness cover 14 is attached to the bracket member 5. In other words, the harness cover 14 is configured to cover both the harness W and the bracket member 5 when attached to the bracket member 5 holding the harness W. The harness cover 14 has flexibility that allows it to be elastically deformed.

[0029] (Structure of bracket member 5) As shown in Fig. 4, the bracket member 5 has a pair of engaging claws 7, 7 facing each other across the storage space 6 that houses the harness W. In other words, when the first direction X is the left-right direction, one engaging claw 7 and the other engaging claw 7 have a symmetrical shape. The one engaging claw 7 and the other engaging claw 7 are arranged spaced apart in the first direction X with the storage space 6 divided by two inner wall surfaces 7a, 7a. The pair of engaging claws 7, 7 have flexibility that allows elastic deformation.

[0030] The pair of engaging claws 7, 7 are configured so that the dimension of the accommodation space 6 in the first direction X (the distance in the first direction X between the two inner wall surfaces 7a, 7a that divide the accommodation space 6) exceeds the cross-sectional diameter of the harness W. With this configuration, when the harness W is accommodated in the accommodation space 6, the harness W is given a degree of freedom to move in the first direction X. This can therefore improve the workability of connecting the harness W to the camera device 11, and is effective when changing the harness W to one with a larger diameter.

[0031] (Retaining structure for harness W) 4, a pair of flexible pieces 8, 8 are provided on a pair of engaging claws 7, 7 of the bracket member 5, forming a push-in opening 8a communicating with the accommodation space 6. One flexible piece 8 extends from a main body portion of one engaging claw 7, and the other flexible piece 8 extends from a main body portion of the other engaging claw 7.

[0032] Each of the pair of flexible pieces 8, 8 extends in an inclined manner (diagonally upward in FIG. 4) toward the accommodation space 6, and a push-in opening 8a is formed between the extending tip of one flexible piece 8 and the extending tip of the other flexible piece 8. A distance d1 between the push-in opening 8a in the first direction X is configured to be smaller than the cross-sectional diameter of the harness W. In addition, one flexible piece 8 is configured to be thinner than the main body portion of one engaging claw portion 7, and the other flexible piece 8 is configured to be thinner than the main body portion of the other engaging claw portion 7.

[0033] The pair of flexible pieces 8, 8 are configured to elastically deform under a load in a pushing direction Y1 when the harness W is pushed into the storage space 6 from outside the storage space 6 through the push-in opening 8a, temporarily expanding the push-in opening 8a, and to return to their original shape after the harness W has passed through. The pushing direction Y1 at this time is defined as one direction of the second direction Y. The pair of flexible pieces 8, 8 can prevent the harness W from slipping out of the storage space 6 by restricting the movement of the harness W in the direction opposite to the pushing direction Y1. Thus, the pair of flexible pieces 8, 8 fulfill the function of accommodating and holding the harness W in the storage space 6.

[0034] (Mounting structure for harness cover 14) As shown in Fig. 4, each of the pair of engaging claws 7, 7 of the bracket member 5 is provided with a protruding portion 9 formed by an outer surface 7b protruding outward from the inner wall surface 7a facing the storage space 6. That is, the protruding portion 9 of one engaging claw 7 and the protruding portion 9 of the other engaging claw 7 each have a protruding shape that protrudes in a direction away from the storage space 6. Each protruding portion 9 has an inclined surface 9a that is inclined such that the dimension in the first direction X gradually increases toward the ceiling 3. The inclined surface 9a extends linearly from a base portion 9b closer to the harness cover 14 to a top portion 9c farther from the harness cover 14.

[0035] (Structure of harness cover 14) 4, the harness cover 14 includes a main body 15 and extending wall portions 16 extending from both ends of the main body 15 in the first direction X toward the ceiling 3. The harness cover 14 is sized so that the distance between the two extending wall portions 16 in the first direction X exceeds the dimension of the pair of engaging claw portions 7, 7 in the first direction X. An engaging piece 17 having a claw shape is provided on an inner wall surface 16a of each extending wall portion 16, which is engageable with the protruding portion 9 of the bracket member 5.

[0036] The harness cover 14 is dimensioned such that the distance d4 between the tip of one engagement piece 17 and the tip of the other engagement piece 17 exceeds the distance d2 in the first direction X between the base 9b of one inclined surface 9a and the base 9b of the other inclined surface 9a, and is smaller than the distance d3 in the first direction X between the top 9c of one inclined surface 9a and the top 9c of the other inclined surface 9a. Therefore, the harness cover 14 is configured such that the engagement piece 17 engages with the protruding portion 9 on the bracket member 5 side by movement in the mounting direction Y2 relative to the bracket member 5, and the engagement piece 17 overcomes and is hooked on the protruding portion 9 (top 9c of the inclined surface 9a) by elastic deformation. At this time, the mounting direction Y2 of the harness cover 14 is substantially the same direction as the push-in direction Y1 of the harness W.

[0037] Next, an assembly operation for assembling the harness W to the vehicle 1 will be described with reference to Figures 5 and 6. This assembly operation includes a pushing operation for pushing the harness W into the accommodation space 6 of the bracket member 5 and an attachment operation for attaching the harness cover 14 to the bracket member 5.

[0038] In the following description, the relative position of the harness W with respect to the bracket member 5 is defined as a first position P1 before the harness W is pushed in, a third position P3 after the harness W is pushed in, and a second position P2 between the first position P1 and the third position P3. Also, the relative position of the harness cover 14 with respect to the bracket member 5 is defined as a first position Q1 before the harness cover 14 is attached, a third position Q3 after the harness cover 14 is attached, and a second position Q2 between the first position Q1 and the third position Q3.

[0039] (Pushing in harness W) 5, the harness W is pushed in prior to the attachment of the harness cover 14. First, the harness W is moved in a push-in direction Y1 from the first position P1 toward the push-in opening 8a of the bracket member 5 and brought into contact with the pair of flexible pieces 8, 8. When the harness W is further moved in the push-in direction Y1 to be disposed at a second position P2, the pair of flexible pieces 8, 8 are elastically deformed by the load received from the harness W so as to expand the push-in opening 8a in the first direction X (see the position indicated by the solid line in FIG. 5).

[0040] Thereafter, when the harness W is further moved in the pushing direction Y1 from the second position P2, the pair of flexible pieces 8, 8 are released from contact with the harness W and return to their original positions due to their elasticity (see the position indicated by the two-dot chain line in FIG. 5). Then, the harness W is in a retained state accommodated in the accommodation space 6 of the bracket member 5 at the third position P3 (see FIG. 4).

[0041] (Installation of harness cover 14) 6, the installation operation of the harness cover 14 is performed after the harness W is pushed in. First, the harness cover 14 is moved in the installation direction Y2 from the first position Q1 toward the pair of engaging claws 7, 7 of the bracket member 5, and at the second position Q2, each engaging piece 17 of the harness cover 14 is brought into contact with the corresponding inclined surface 9a of the bracket member 5.

[0042] When the harness cover 14 is further moved in the mounting direction Y2, each of the engagement pieces 17 slides along the inclined surface 9a of each of the protrusions 9 toward the top 9c. Therefore, the harness cover 14 elastically deforms so as to gradually expand the distance between the two engagement pieces 17 (see distance d4 in FIG. 4) according to the inclination angle of the inclined surface 9a. At this time, at least one of the main body 15, the extending wall 16, and the engagement pieces 17 of the harness cover 14 can elastically deform. In addition, in conjunction with the elastic deformation of the harness cover 14 at this time, the pair of engagement claws 7, 7 of the bracket member 5 also elastically deform in a direction approaching each other under the pressure load from each of the engagement pieces 17 of the harness cover 14.

[0043] Thereafter, each engagement piece 17 of the harness cover 14 climbs over the top 9c of the inclined surface 9a of each protrusion 9, and returns to its original position due to its elasticity. Then, this harness cover 14 is fitted into the protrusion 9 of the bracket member 5 at the third position Q3, and is in an attached state where it is hooked onto the protrusion 9 (see FIG. 4).

[0044] The effects of the above-mentioned first embodiment will be described below.

[0045] In the assembly structure 10 of the first embodiment, the harness W is held by a bracket member 5 provided on the vehicle 1. At this time, the bracket member 5 is an attachment target to which the harness W is attached. The bracket member 5 is also an attachment target to which the harness cover 14 is attached. In other words, the bracket member 5 is an attachment target to which both the harness W and the harness cover 14 are attached.

[0046] If the bracket member 5 is used as a mounting target for both the harness W and the harness cover 14, the space required for mounting the harness W and the harness cover 14 can be reduced, which is effective in reducing the size of the assembly structure 10 compared to when the mounting target for the harness W and the mounting target for the harness cover 14 are different members. When the harness cover 14 is mounted on the bracket member 5 holding the harness W, both the harness W and the bracket member 5 are covered by the harness cover 14.

[0047] As described above, according to the first embodiment, it is possible to reduce the size of the assembly structure 10 that assembles the harness W to the vehicle 1. In addition, the size of the assembly structure 10 can be reduced, which is effective in reducing the material costs of the bracket member 5 and the harness cover 14.

[0048] According to the assembly structure 10 configured as above, it is possible to hold the harness W by utilizing a simple structure in which the harness W is pushed into the housing space 6 through the push-in opening 8a between the pair of flexible pieces 8, 8 of the bracket member 5.

[0049] According to the assembly structure 10 configured as described above, it is possible to attach the harness cover 14 to the bracket member 5 by utilizing a simple structure in which the engagement pieces 17 of the harness cover 14 are fitted into the protrusions 9 provided on each of a pair of engagement claw portions 7, 7 of the bracket member 5.

[0050] According to the assembly structure 10 configured as described above, by matching the pushing direction Y1 in which the harness W is pushed into the storage space 6 of the bracket member 5 with the mounting direction Y2 in which the harness cover 14 is attached to the bracket member 5, the operation of the harness cover 14 and the bracket member 5 is unified and simplified, thereby improving the overall workability related to assembling the harness W.

[0051] The present invention is not limited to the above-described embodiment, and various applications and modifications are possible without departing from the scope of the present invention. For example, the following embodiments can be implemented by applying the above-described embodiment.

[0052] In the above embodiment, an example was given of the harness cover 14 being attached by fitting it into the protrusion 9 of the bracket member 5, but instead, the harness cover 14 may be attached to the bracket member 5 using screws, adhesives, etc.

[0053] In the above-described embodiment, an example was given of a case in which the pushing-in direction Y1 of the harness W and the mounting direction Y2 of the harness cover 14 are the same direction, but instead, a structure can be adopted in which the pushing-in direction Y1 and the mounting direction Y2 are different directions.

[0054] In the above embodiment, the harness cover 14 is a resin part separate from the camera cover 13, but instead of this, a structure in which the harness cover 14 is connected to the camera cover 13 by a thin resin hinge can be adopted. Even in the case of this structure, the harness cover 14 can be attached to the bracket member 5 after the camera cover 13 is attached.

[0055] In the above embodiment, an assembly structure 10 for assembling the harness W of the camera device 11 for collision avoidance assistance to the vehicle 1 has been illustrated, but this assembly structure 10 can also be applied to an assembly structure for assembling a harness of an in-vehicle device other than the camera device 11 to the vehicle 1. Examples of the other in-vehicle device include a camera module for a drive recorder, a camera module for passenger monitoring, a light collecting sensor, a humidity sensor, a head-up display, and a monitor unit of an electronic door mirror. In addition, the object to be assembled to the vehicle 1 is not limited to only the harness W, and instead of the harness W, for example, a string-like member such as a metal wire member or a hose may be used.
