[0006]
Note that the combined closed space extending in the lateral direction of the vehicle does not necessarily need to cover the entire width in the lateral direction of the vehicle, and it is sufficient if the combined closed space is configured at least at a place where the electrical component is attached. Moreover, the synthetic | combination closed space extended in a vehicle horizontal direction may be formed intermittently.
[0007]
According to the vehicle ceiling structure of the present invention as set forth in claim 1, the vehicle interior electrical component forms a combined closed space that extends in the vehicle lateral direction together with the reinforcing bar recess, thereby improving the vehicle roof rigidity. For this reason, a heavy electrical component can be attached to the vehicle roof to withstand the load of the electrical component, and the roof structure has a high strength against external forces. Further, by forming the synthetic closed space with the reinforcing bar recess and the electrical component, the number of parts can be reduced as compared with the case where the closed space is formed only with the reinforcing bar and the electrical component is attached.
In addition, the connector of the electrical component is connected to the power supply connector on the vehicle body side, and the electrical component is connected to the power source on the vehicle body side. The wire harness of the electrical component is disposed in the synthetic closed space between the electrical component and the reinforcing bar recess. In this way, when the electrical component constitutes the synthetic closed space together with the reinforcing bar recess, the electrical component wire harness can be disposed in the synthetic closed space, and the electrical component wire harness can be placed outside the synthetic closed space. Instead, the vehicle ceiling space can be effectively used by arranging it in the synthetic closed space.

Here, the second closed space constituent part and the reinforcing bar concave part coexist. Thus, while providing the 2nd closed space structure part in a reinforcement bar previously, and comprising a synthetic closed space by a reinforcement bar recessed part and an electrical component, load resistance improves further.
[0012]
According to a third aspect of the present invention, there is provided a vehicle ceiling structure according to the first or second aspect , wherein the electric component covers the electrical component and an opening is formed so that the functional unit of the electrical component is moved into the vehicle interior. An interior ceiling to be faced is attached to the ceiling portion from the indoor side of the electrical component, and an engagement means that engages with each other is provided at a peripheral edge of the opening and the electrical component so that the interior ceiling is connected to the electrical component. It is characterized by being attached to.
[0013]
According to the vehicle ceiling structure of the present invention described in claim 3 , the electrical component is covered from the indoor side by the interior ceiling, and the functional part of the electrical component faces the vehicle interior through the opening of the interior ceiling. Here, the interior ceiling is attached to the electrical component by the engagement means of the peripheral edge of the opening of the interior ceiling and the engagement unit of the electrical component being engaged. Thus, since the interior ceiling and the electrical component are engaged with each other, the assembly parts can be omitted, and the appearance of the interior ceiling viewed from the indoor side is not impaired. Further, by providing the engaging means at the periphery of the opening of the interior ceiling, the periphery of the opening is reinforced, and at the time of attaching the interior ceiling, the engaging means is positioned.
[0014]
The vehicle ceiling structure according to a fourth aspect of the present invention is the vehicle ceiling structure according to any one of the first to third aspects, wherein the electrical component includes a base member, and the base member is attached to the reinforcing bar. And a synthetic closed space is formed between the reinforcing bar recesses.
[0015]
According to the vehicle ceiling structure of the present invention as set forth in claim 4 , since the base member to which the electrical components are attached in advance is attached to the reinforcing bar, the degree of freedom in the shape of the portion where the base member is attached to the reinforcing bar is large and suitable for attachment. Can be shaped. It is also convenient when many electrical components are assembled to the vehicle roof at a time. The reinforcing bar supports the load of the electrical component through the base member. Here, as the number of electrical components to be attached increases, the load supported by the reinforcing bar also increases, but the vehicle roof rigidity is improved by forming a closed space between the base member and the recessed portion of the reinforcing bar. Can withstand.

[0033]
Next, in the above embodiment, an operation procedure when the electrical module 20 and the interior ceiling 42 as shown in FIG. 3 are assembled to the vehicle roof 11 will be described.
[0034]
First, as shown in FIG. 2, the module substrate 22 is fixed to the lean hose 16, the stay 19, and the side member front portion 14 </ b> A with bolts 24. Next, the connector 29 of the electrical component wire harness 28 that protrudes to the outside of the module substrate 22 in the vehicle width direction (arrow W direction), and the power supply connector 31 of the vehicle body side wire harness 30 that extends to the vicinity of the upper portion of the pillar 32 Are connected.

In this state, most of the electrical module 20 and the upper part of the vehicle body side wire harness 30 are covered with the interior ceiling 42 and are hidden from the passenger compartment 100.
[0036]
In this way, by assembling the interior ceiling 42 after wiring, it is not necessary to perform wiring while supporting the interior ceiling 42, so that wiring work is easy. For example, in an automobile assembly line, the connection work of the electrical component connector 29 and the power supply connector 31 shown in FIG. Further, as shown in FIG. 1, since the engaging claw portion 44E is provided and locked to the locking portions 40B and 38A, the positioning can be accurately performed and the assembly can be quickly performed.
[0037]
Next, the operation of the above embodiment will be described.
[0038]
As shown in FIG. 1, since a module substrate 22 to which various electrical components such as a camera unit 34 and electrical components 38 are previously attached is attached to the lean hose 16 on the vehicle roof 11, the module substrate 22 is attached to the lean hose 16. The part has a large degree of freedom in shape and can be made into a shape suitable for mounting. It is also convenient when many electrical components are assembled to the vehicle roof 11 at a time. The load of various electrical components such as the camera unit 34 and the electrical component 38 is supported by the lean hose 16 via the module substrate 22. Here, when the electrical components to be attached to the module substrate 22 increase, the load supported by the lean hose 16 also increases. However, since the synthetic closed space 26 is formed between the module substrate 22 and the lean hose recess 17A, the vehicle roof rigidity is increased. Can withstand large loads.
[0039]
In addition, since the closed space structure part 15 is previously formed in the lean hose 16, the closed space structure part 15 and the synthetic | combination closed space 26 coexist. As described above, the closed space constituting portion 15 is provided in the lean hose 16 in advance, and the synthetic closed space 26 is constituted by the lean hose concave portion 17A and the module substrate 22, thereby further improving load resistance.

As shown in FIG. 2, the electrical component connector 29 is connected to the vehicle body side power supply connector 31 at the top of the pillar 32, and the electrical component module 20 is connected to the vehicle body side power source. As shown in FIG. 1, the electrical component wire harness 28 is disposed in the synthetic closed space 26 between the module substrate 22 and the lean hose recess 17 </ b> A. As described above, the module substrate 22 forms the synthetic closed space 26 together with the lean hose recess 17 </ b> A, whereby the electrical component wire harness 28 can be disposed in the synthetic closed space 26, and the electrical component wire harness 28. Is placed not in the synthetic closed space 26 but in the synthetic closed space 26, the vehicle ceiling space can be effectively used.
[0041]
The spectacle case 40, the electrical component 38, and the like are covered from the passenger compartment 100 side by the interior ceiling 42, and the spectacle case penetration 44A and the electrical component penetration 44B of the design frame 44 temporarily assembled to the interior ceiling 42 are provided. Then, the operation part (functional part) of the glasses case 40 and the electrical component 38 faces the passenger compartment 100. The lid 40A of the glasses case 40 can be opened and closed from the passenger compartment 100 side. Here, the engaging claw portions 44E at the periphery of the spectacle case penetration portion 44A and the electrical component penetration portion 44B of the design frame 44 are connected to the engagement portion 40B of the spectacle case 40 and the engagement portion 38A of the electrical component 38. By engaging, the interior ceiling 42 is assembled to the electrical module 20.
[0042]
Thus, since the interior ceiling 42 and the electrical module 20 are engaged with each other, an assembly part (for example, a fixing clip) can be omitted, and the simple interior ceiling 42 viewed from the passenger compartment 100 side can be omitted. Appearance is not impaired. Further, by providing engagement claw portions 44E at the peripheral edges of the spectacle case through portion 44A and the electrical component through portion 44B of the design frame 44, the peripheral portions of the spectacle case through portion 44A and the electrical component through portion 44B are reinforced. At the same time, when the interior ceiling 42 is attached, it is also positioned by the engaging claw portion 44E.
[0043]
Also, by changing the design frame 44, the interior ceiling 42 can be handled as an option, so that the types of interior ceiling 42 need not be increased. In addition, operations such as parts repair and replacement above the interior ceiling 42 can be performed by removing the design frame 44, which is convenient.
[0044]
Although not specifically shown in the above embodiment, the interior ceiling 42 may be assembled with an impact absorbing material, a sound absorbing material, an air conditioning duct, or the like to ensure the rigidity of the interior ceiling 42. When the rigidity of the interior ceiling 42 is ensured, the interior ceiling 42 is easily assembled.
[0045]
Further, in the above-described embodiment, the stay 19 is not formed with a recess opening toward the passenger compartment 100, but like the lean hose 16, such a recess is provided and the vehicle between the module board 22 and the stay 19 is provided. You may comprise the synthetic | combination closed space extended in a horizontal direction.
[0046]
In the above embodiment, the module substrate 22 is fastened by the bolt 24 at the concave portion 18A and the bent rear portion 17C of the lean hose 16, but the fastening position by the bolt 24 is not limited to this, for example, It is good also considering the bending front part 17B of the lean hose 16 as one of the fastening locations. The module substrate 22 is fastened to the lean hose 16, the stay 19, and the side member 14. For example, the module substrate 22 is fastened to either the stay 19 or the side member 14 and the lean hose 16, or only the lean hose 16. May be fastened.
[0047]
Furthermore, in the above-described embodiment, the case where the temporary fixing of the electrical component wire harness 28 on the upper surface side of the module substrate 22 is described by using a tape (not shown) as an example. Alternatively, an accommodation groove may be provided on the upper surface side of the module substrate 22 so as to be routed in the accommodation groove, and the temporary fixing method is not limited to that using a tape.
[0048]
Furthermore, in the above embodiment, the module substrate 22 to which the electrical components are assembled forms a closed cross-sectional structure surrounding the synthetic closed space 26 with the lean hose recess 17A, but without the module substrate 22 being interposed. The electrical component may be directly attached to the lean hose 16, and a closed cross-sectional structure surrounding the synthetic closed space may be formed between the electrical component and the lean hose recess 17A. At this time, the electrical component is not limited to a plurality, and may be a single unit. In addition, you may store components which do not require maintenance other than the wire harness for electrical components in the synthetic | combination closed space.
