Description

[Technical Field]

[0001] The technology disclosed in this specification relates to vehicle interior materials. [Background technology]

[0002] For example, a door trim, which is an interior material for a vehicle, is made up of a combination of multiple board members. Patent Document 1 listed below describes a technology that, when a part of the multiple board members (base interior) that make up the door trim (vehicle interior member) becomes dirty or damaged, allows for the replacement of just that board member without removing the entire door trim from the vehicle body.

[0003] Specifically, the vehicle interior component of Patent Document 1 is one in which a portion can be removed and attached from inside the vehicle cabin, and multiple plate-shaped locking pieces protrude from the inner periphery of the opening that is exposed when a removable component (board component) of the vehicle interior component is removed.The removable component can be attached by inserting the insertion portion of the removable component into the insertion hole provided in these locking pieces and sliding it along the slit connected to the insertion hole, thereby blocking the opening.

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-83266 Summary of the Invention [Problem to be solved by the invention]

[0005] Recently, there has been a demand for easier customization of vehicle interior materials to suit user preferences. In particular, there is a demand for the attachment of electrical components that require a power source, such as illumination panels, to enhance design and functionality. To enable the attachment of electrical components to the above-described conventional vehicle interior members, it is necessary to provide a connector portion for supplying power to the opening.

[0006] On the other hand, the above-mentioned conventional vehicle interior components are premised on the replacement of the attachable member (board member). Therefore, when the attachable member is removed, the opening and the locking structure are exposed to the interior of the vehicle, and the vehicle interior components cannot be used as is. However, there is a demand for a vehicle interior material that can be used in the detached state when the attachable member is not needed.

[0007] The technology disclosed in this specification was developed based on the above circumstances, and aims to provide a vehicle interior material that can be fitted with electrical components and that has excellent design even when used with the electrical components removed when the electrical components are not required. [Means for solving the problem]

[0008] The technology disclosed in this specification, which was completed in consideration of the above-mentioned problems, is a vehicle interior material comprising: a trim board that constitutes the interior surface of a vehicle; and an electrical component that is detachably attached to the interior surface of the trim board, wherein the trim board comprises an accommodation recess that is recessed from the interior surface toward the exterior of the vehicle and that accommodates at least a portion of the electrical component that is arranged on the exterior side, and a board-side connector portion that is provided inside the accommodation recess and that supplies power to the electrical component, wherein the electrical component comprises a box-shaped main body and a component-side connector portion that is provided in a position facing the board-side connector portion when the main body is accommodated in the accommodation recess, and the board-side connector portion is provided on an inner wall of the accommodation recess that intersects with a main surface that is a main body of the trim board, and is recessed from the inner wall of the accommodation recess, and the electrical component is accommodated in the accommodation recess, and then the electrical component can be accommodated in the accommodation recess and then slid toward the board-side connector portion, whereby the component-side connector portion is connected to the board-side connector portion and is attached to the accommodation recess.

[0009] According to the above configuration, the trim board is provided with a board-side connector capable of supplying power, allowing electrical components to be attached to the trim board. The storage recess for attaching the electrical components is closed off from the exterior of the vehicle, and the board-side connector for electrically connecting the electrical components is recessed from the inner wall of the recess and positioned so as to be difficult for occupants to see. Therefore, the trim board has excellent design even when the electrical components are removed, and can be used with the electrical components removed when they are not needed.

[0010] The trim board may constitute a door trim of a vehicle door, the recess inner wall may include an upper wall extending in the fore-and-aft direction of the vehicle and positioned relatively upward, and the board-side connector portion may be provided on the upper wall.

[0011] According to the above configuration, when the door trim is viewed from the front or diagonally above, which is the line of sight of the occupant, the board-side connector portion is less visible to the occupant, further improving the design when no electrical components are used.

[0012] The accommodating recess may be provided with a locking member for holding the electrical component in the mounted state, and the electrical component may have an engaged portion that is engaged with the locking member, and the locking member may be configured to displace as the electrical component slides from the accommodated state toward the board side connector portion within the accommodating recess, and to engage with the engaged portion when the electrical component reaches the mounted state.

[0013] According to the above configuration, the electrical component is automatically locked by the locking member when it is brought into the mounted state, which makes it easier to mount the electronic component and also makes it possible to stably maintain the mounted state of the electronic component.

[0014] When the electric component is not disposed in the accommodating recess, the locking member has a strip shape having at least a first portion disposed along the upper wall and a second portion that is bent and continues from the first portion and is disposed along a vertical wall of the recess inner wall of the accommodating recess that is disposed on the front side or the rear side of the vehicle, and is rotatable around a rotation axis that is provided at a boundary between the first portion and the second portion and extends in a vehicle interior / exterior direction, and the electric component is disposed in front of the locking member when the accommodating recess is in the accommodated state. The electrical component may be provided with a rotation operating part at a position opposite the first part, and as the electrical component slides from the accommodated state toward the board side connector part within the accommodation recess, the rotation operating part abuts against the first part of the locking member and pushes up the first part from below, causing the locking member to rotate around the rotation axis, and when the electrical component is in the installed state, the second part may be configured to lock the stepped locked part provided on the exterior surface of the main body by supporting it from below.

[0015] According to the above configuration, when the electrical components are removed from the trim board, the locking member is arranged along the inner surface of the recess, making it difficult for occupants to see, and thus improving the design of the trim board. Furthermore, when the electrical components are installed, the locking member is arranged in a position that is not visible to occupants, so the design is not impaired. Furthermore, because the locking member is arranged in a direction that follows the surface of the trim board as a whole, it can fulfill a reinforcing function against impacts during a side collision and loads from above.

[0016] The locking member may have a third portion that is bent and connected to the lower end of the second portion when the electrical component is not placed in the accommodating recess, and the third portion may be configured to lock a stepped second lockable portion provided on the exterior surface of the main body by supporting it from below when the electrical component is in the installed state.

[0017] According to the above configuration, the electrical component can be held more stably than in a configuration in which the locking member does not have the third portion.

[0018] A guide hole penetrating the plate surface of the first portion of the locking member may be formed, and an arc-shaped guide portion may be provided on the trim board side to be inserted into the guide hole and to guide the rotational position of the first portion.

[0019] The guide portion may be provided with a lock portion for locking the orientation of the first portion when the electrical component is in the attached state.

[0020] According to the above configuration, the locking portion maintains the electrical component attached to the trim board, and prevents the component-side connector portion from unintentionally detaching from the board-side connector portion.

[0021] The accommodating recess may be provided adjacent to a side end of the door trim, and the locked state of the locking section may be released by inserting an unlocking pin through an unlocking hole provided in the side end of the door trim.

[0022] A cover may be provided on a surface of the main body of the electrical component that faces the interior of the vehicle, the cover covering the accommodating recess from the interior side when the electrical component is in the installed state. With this configuration, it is possible to further improve the design when the electrical component is installed in the accommodating recess.

[0023] The electrical component may be an illumination panel that emits light toward the interior of the vehicle. [Effects of the Invention]

[0024] According to the technology disclosed in this specification, it is possible to provide a vehicle interior material that can be fitted with electrical components and that has excellent design even when used with the electrical components removed if the electrical components are not required.

[0026] <Embodiment 1> A door trim 10, which is a vehicle interior material of the first embodiment, will be described with reference to Figures 1 to 11. The symbols FR, RR, UP, DW, IN, and OUT shown in each figure respectively indicate the front and rear in the longitudinal direction of a vehicle as an example of a vehicle, the upper and lower in the vertical direction, and the interior and exterior sides in the interior-exterior direction of the vehicle. However, these directions are merely defined for convenience and should not be interpreted in a restrictive manner. The front side of the door trim 10 is defined as viewed from the interior side.

[0027] 1 is a perspective view of a door trim 10 as seen from the interior side. The door trim 10 is mainly composed of a generally plate-shaped trim board 11, and is fastened to the interior side of a door inner panel (not shown) by fastening members such as clips (not shown), thereby improving the design and livability of the vehicle interior. The trim board 11 is made of, for example, a synthetic resin (thermoplastic resin) such as polypropylene, or a composite material such as a mixture of plant fiber (for example, kenaf) and synthetic resin.

[0028] The trim board 11 is formed by assembling a plurality of board members together. Although not shown in detail, the trim board 11 of this embodiment is mainly formed by an upper board 12, a lower board 13, an armrest board 14, etc. Of these, the upper board 12 is a portion disposed above the armrest 15, and forms a portion including the front edge, upper edge, and rear edge of the trim board 11. The interior-facing surface (surface) of the trim board 11 may be covered with a skin material (not shown) made of natural leather, synthetic leather, fabric, or the like.

[0029] In this embodiment, a storage recess 20 recessed toward the exterior is provided in a portion of the upper board 12 adjacent to the rear end. More specifically, as shown in Fig. 2, the storage recess 20 has a rectangular shape that is horizontally elongated when viewed from the front and is slightly flattened toward the interior and exterior of the vehicle, carved out of a main surface (main surface 12A) of the upper board 12. The storage recess 20 can also be described as having a box shape that opens toward the interior of the vehicle.

[0030] Hereinafter, among the wall portions constituting the storage recess 20, the wall portion arranged in a direction along the main surface 12A of the upper board 12 will be referred to as the bottom wall 21, the wall portion arranged above the bottom wall 21 as the upper wall 22, the wall portion arranged below as the lower wall 27, the wall portion arranged in front as the front wall 24, and the wall portion arranged in the rear as the rear wall 25. Of these, a decorative film is attached to the bottom wall 21. Of these, the upper wall 22, the lower wall 27, the front wall 24, and the rear wall 25 correspond to the recess inner walls of the technology disclosed in this specification. The bottom wall 21 extends in the vehicle longitudinal direction and in the vertical direction. The upper wall 22 and the lower wall 27 extend in the vehicle longitudinal direction and in the interior and exterior directions of the vehicle. The front wall 24 and the rear wall 25 extend in the vertical direction and in the interior and exterior directions of the vehicle (examples of vertical walls).

[0031] A board-side connector portion 28 is provided on the upper wall 22 of the accommodation recess 20 (see FIGS. 4 and 7). The board-side connector portion 28 is an electrical connection portion for supplying power to an illumination panel 50 (described later), and is a female connector provided in a central portion of the upper wall 22 in the front-to-rear direction, closer to the exterior of the vehicle cabin in the interior-exterior direction, and recessed upward from the upper surface of the accommodation recess 20. More specifically, a box-shaped recess 22A is provided on the upper wall 22, and the board-side connector portion 28 is formed by surrounding a connection terminal 28A disposed inside the recess 22A. The recess 22A can also be said to constitute a housing (peripheral wall) of the board-side connector portion 28. With this configuration, the board-side connector portion 28 is difficult for an occupant to see when the door trim 10 is viewed from the front or obliquely above, which is the line of sight of the occupant (see FIG. 4).

[0032] An illumination panel 50 (an example of an electrical component) is detachably attached to the accommodation recess 20. The illumination panel 50 is capable of emitting light by being connected to the board-side connector portion 28, and provides illumination to the interior of the vehicle. As shown in Figures 2 to 4, the illumination panel 50 is configured to include a main body portion 51, a cover portion 52 arranged on the interior surface of the main body portion 51, a panel-side connector portion 53 and a rotation operation pin (an example of a rotation operation portion) 54 arranged on the upper surface of the main body portion 51, and an engaged portion 55 formed on the exterior surface of the main body portion 51.

[0033] The main body 51 has a flat box shape that can be accommodated in the above-described storage recess 20 of the upper board 12. In detail, when the main body 51 is described using the state in which it is accommodated in the storage recess 20 as a reference direction, its front-to-rear dimension is approximately equal to the front-to-rear dimension of the storage recess 20, its up-to-down dimension is slightly shorter than the up-to-down dimension of the storage recess 20, and its dimensions in the interior-to-exterior directions are approximately equal to the interior-to-exterior dimensions of the storage recess 20, with some exceptions. In other words, when the main body 51 is accommodated in the storage recess 20, it fits snugly into the storage recess 20 in the vehicle front-to-rear direction and the interior-to-exterior direction. In other words, the main body 51 forms a flush surface that is continuous with the main surface 12A of the upper board 12, and in the up-to-down direction, there is a gap between the main body 51 and the upper wall 22 or the lower wall 27 of the storage recess 20, allowing it to be accommodated in a state in which it can move up and down (see FIG. 5 ). The surface of the main body 51 facing the room is made of a light-transmitting material, and a light source capable of emitting light toward the room side is disposed inside the main body 51 (not shown).

[0034] A translucent cover portion 52 is provided integrally with the interior-facing surface of the main body portion 51. The cover portion 52 is a plate-like member having approximately the same dimensions as the opening of the storage recess 20 of the upper board 12, and is integrated with the main body portion 51 such that its upper end coincides with the upper end of the main body portion 51 and its front and rear ends coincide with the front and rear ends of the main body portion 51. In other words, when the cover portion 52 is attached to the main body portion 51, its lower portion protrudes downward from the lower end of the main body portion 51.

[0035] A panel-side connector portion (an example of a component-side connector portion) 53 is provided on the upper surface of the main body portion 51 at a position facing the board-side connector portion 28 when the illumination panel 50 is disposed in the accommodating recess 20. The panel-side connector portion 53 is a male connector that protrudes in a box shape from the upper surface of the main body portion 51 (see FIGS. 2 and 3). The panel-side connector portion 53 and the board-side connector portion 28 are sized so that, when they are mated (electrically connected), the main body portion 51 of the illumination panel 50 is overlapped with the upper wall 22 of the accommodating recess 20 with almost no gap (see FIGS. 6 and 8). Furthermore, when the panel-side connector portion 53 is mated with the board-side connector portion 28 (when the illumination panel 50 is installed in the correct position in the accommodating recess 20), the cover portion 52 closes the opening of the accommodating recess 20 (see FIG. 6).

[0036] A rotation operation pin (an example of a rotation operation portion) 54 is provided at a position rearward of the panel-side connector portion 53, toward the rear end of the main body portion 51 and adjacent to the outside of the vehicle cabin. The rotation operation pin 54 is formed in a round bar shape, and the protruding dimension thereof from the main body portion 51 is substantially the same as the protruding dimension of the panel-side connector portion 53. The rotation operation pin is not limited to a round bar shape, and may be formed in a square bar shape.

[0037] Furthermore, a locking portion 55 is provided on the exterior surface of the main body 51. As shown in Figures 3 and 7, the locking portion 55 is configured by a combination of a first step portion 56 that extends linearly downward and forward from near a corner of the upper end of the rear side of the vehicle of the main body 51 and has a stepped shape in the interior and exterior of the vehicle, and a second step portion 57 that extends perpendicularly upward and forward from the lower end of the first step portion 56 and has a stepped shape in the interior and exterior of the vehicle. The first step portion 56 and the second step portion 57 have a stepped shape with their upper sides disposed on the exterior side and their lower sides disposed on the interior side.

[0038] Meanwhile, a hook (an example of a locking member) 40 capable of locking the illumination panel 50 is provided in the accommodation recess 20 of the door trim 10 in a state in which it can rotate relative to the accommodation recess 20 (see FIG. 2). In the following description, the natural state in which the hook 40 does not lock the illumination panel 50 will be referred to as an unlocked state, and the state in which the hook 40 has rotated to lock the illumination panel 50 will be referred to as a locked state. In the following description of the hook 40, the unlocked state will be used as the reference direction.

[0039] The hook 40 is rotatable about a pivot 45 extending along a corner between the upper wall 22 and the rear wall 25 of the storage recess 20, and is formed by bending a thin, strip-like member into a generally U-shape. Specifically, as shown in FIG. 7 , the hook 40 has a first portion 41 extending in the vehicle longitudinal direction along the upper wall 22 of the storage recess 20 with its plate surface facing up and down, a second portion 43 bent downward at a right angle from the rear end of the first portion 41 and extending along the rear wall 25 of the storage recess 20, and a third portion 44 bent forward at a right angle from the lower end of the second portion 43 (toward the inside of the storage recess 20) and extending along the bottom wall 27 of the storage recess 20. The pivot 45 is integrally provided at the boundary (corner) between the first portion 41 and the second portion 43.

[0040] In the unlocked state, the first portion 41 is disposed so as to overlap the upper surface of the upper wall 22. The second portion 43 has a vertical dimension equal to the vertical dimension of the rear wall 25, is disposed within the first escape hole 26 provided in the rear wall 25, and is disposed so that its front surface 43A is flush with the front surface 25A of the rear wall 25 of the storage recess 20 (see FIGS. 2, 7, and 8). The third portion 44 is disposed within the second escape hole 29 provided in the lower wall 27, and is disposed so that its upper surface 44A is flush with the upper surface 27A of the lower wall 27 of the storage recess 20. With this configuration, the hook 40 is difficult for the occupant to see in the unlocked state (see FIG. 2). The width dimension of the hook 40 (dimension from the inside to the outside of the vehicle interior) is smaller than the depth dimension (dimension from the inside to the outside of the vehicle interior) of the storage recess 20, and the hook 40 is arranged at the end of the storage recess 20 on the bottom wall 21 side (outside the vehicle interior) (see Figure 4).

[0041] Such a hook 40 rotates around the above-mentioned pivot axis 45 and is displaceable between an unlocked state (see Figure 7) in which the first part 41 and the third part 44 extend in the front-to-back direction and the second part 43 extends in the up-to-down direction, and an locked state (see Figure 8) in which the hook 40 rotates counterclockwise from the unlocked state in Figure 7 and the first part 41 to the third part 44 are each arranged in an inclined state.

[0042] The first portion 41 of the hook 40 has a guide hole 42 formed therethrough. An arc-shaped guide portion 30 is provided on the upper surface of the upper wall 22 of the accommodation recess 20, and is inserted into the guide hole 42 to guide the rotational position of the first portion 41 and therefore the entire hook 40. The guide portion 30 is provided rearward (closer to the end) than the position where the rotation operation pin 54 is disposed. The guide portion 30 also has a lock portion 31 for locking the position of the first portion 41 and therefore the entire hook 40 when the illumination panel 50 is in the above-mentioned attached state.

[0043] 10 and 11, the locking portion 31 is biased to protrude toward the inside of the arc-shaped guide portion 30 and is provided in a state in which it can move forward and backward, and includes a claw portion 32 that can lock the first portion 41 of the hook 40 from below (restricting the downward movement of the first portion 41), and an unlocking portion 34 that is disposed above the claw portion 32. The claw portion 32 and the unlocking portion 34 are spaced apart by a distance that allows the first portion 41 to be disposed therebetween. The claw portion 32 and the unlocking portion 34 are also integrally connected by a connecting portion 33 inside the guide portion 30. In other words, the claw portion 32 and the locking portion 31 move forward and backward in conjunction with each other.

[0044] In such a door trim 10, when the illumination panel 50 is not disposed in the storage recess 20 and the interior of the storage recess 20 is exposed to the interior of the vehicle (see FIGS. 2 and 4). However, the storage recess 20 is closed from the exterior by the bottom wall 21 and is decorated with a decorative film (not shown), and the board-side connector portion 28 is located in a position that is difficult for the occupants to see, and the hook 40 is also configured to be difficult to see. Therefore, the door trim 10 can be used in the unattached state without impairing the interior design.

[0045] When installing the illumination panel 50, the illumination panel 50 is installed in the installation recess 20 with the panel-side connector portion 53 facing upward (installed state, see FIGS. 5 and 7), and then slid upward so that the panel-side connector portion 53 fits with the board-side connector portion 28 (installed state, see FIGS. 6 and 8), enabling the panel to receive power. In the installed state, a gap is generated between the bottom wall 27 of the installation recess 20 and the main body portion 51, but this gap is closed by the cover portion 52, so the design surface of the door trim 10 is continuous, resulting in a good appearance.

[0046] 7 and 8, as the illumination panel 50 is slid from the storage state to the attached state, the rotation operation pin 54 passes through the through-hole 23 provided in the upper wall 22 and pushes the first portion 41 of the hook 40 upward, causing the entire hook 40 to rotate around the rotation axis 45. As a result, the second portion 43 of the hook 40 supports the first step portion 56 of the illumination panel 50 from below, and the third portion 44 supports the second step portion 57 from below, thereby locking the main body portion 51. In other words, the second portion 43 and the third portion 44 of the hook 40 lock the main body portion 51 from different directions.

[0047] At this time, the first part 41 of the hook 40 is maintained in its inclined position by the locking part 31, so the position of the entire hook 40 is maintained, thereby stably maintaining the attached state of the illumination panel 50 in the storage recess 20.

[0048] Furthermore, the locked state of the locking unit 31 can be released by inserting an unlocking pin 60 through an unlocking hole 16 provided at the side end of the door trim 10 and pressing the unlocking unit 34 (see Figures 1 and 9).

[0049] Next, the effects will be described. The door trim 10 of this embodiment includes a trim board 11 that constitutes the interior surface of the vehicle, and an illumination panel 50 that is detachably attached to the interior surface of the trim board 11. The trim board 11 includes a storage recess 20 that is recessed from the interior surface toward the exterior and that stores the illumination panel 50, and a board-side connector portion 28 that is provided inside the storage recess 20 and that supplies power to the illumination panel 50. The illumination panel 50 includes a box-shaped main body portion 51, and a connector portion 28 that is provided in a position that faces the board-side connector portion 28 when the main body portion 51 is stored in the storage recess 20. The board-side connector portion 28 is recessed from the upper wall 22, which is one of the wall portions constituting the accommodating recess 20 and intersects with the main surface 12A that is the main body of the trim board 11 (upper board 12), and the panel-side connector portion 53 is provided protruding from the main body portion 51. After the illumination panel 50 is accommodated in the accommodating recess 20, the illumination panel 50 is slid toward the board-side connector portion 28, whereby the panel-side connector portion 53 is fitted (connected) to the board-side connector portion 28 and attached to the accommodating recess 20.

[0050] According to the above configuration, the trim board 11 is provided with a board-side connector portion 28 capable of supplying power thereto, making it possible to attach the illumination panel 50 to the trim board 11. Furthermore, the accommodation recess 20 for attaching the illumination panel 50 is closed off from the outside of the vehicle compartment, and the board-side connector portion 28 for electrically connecting to the illumination panel 50 is recessed from the upper wall 22 and positioned so as to be difficult for occupants to see. Therefore, the trim board 11 has excellent design even when the illumination panel 50 is removed, and can be used with the illumination panel 50 removed when it is not needed.

[0051] In addition, since the board side connector part 28 is provided on the upper wall 22, when the door trim 10 is viewed from the front or obliquely from above, which is the line of sight of the occupant, the board side connector part 28 is less visible to the occupant, and the design is further improved when the illumination panel 50 is not used.

[0052] In addition, the storage recess 20 is provided with a hook 40 for holding the illumination panel 50 in an installed state, and the illumination panel 50 is provided with an engaging portion 55 that engages with the hook 40. The hook 40 is displaced as the illumination panel 50 slides from the storage state within the storage recess 20 toward the board side connector portion 28, and is configured to engage with the engaging portion 55 when the illumination panel 50 is in an installed state.

[0053] According to the above configuration, the illumination panel 50 is automatically engaged by the hook 40 when it is installed, which makes it easier to install the illumination panel 50 and also makes it possible to stably maintain the installed state of the illumination panel 50.

[0054] When the illumination panel 50 is not disposed in the accommodation recess 20, the hook 40 has a strip-like shape including a first portion 41 disposed along the upper wall 22 and a second portion 43 that is bent and connected to the first portion 41 and disposed along the rear wall 25 of the accommodation recess 20, and is rotatable around a rotation axis 45 that is provided at the boundary between the first portion 41 and the second portion 43 and extends in the interior and exterior directions of the vehicle. The illumination panel 50 has a rotation operation pin 54 that protrudes from the surface of the main body 51 where the panel-side connector portion 53 is provided, and the rotation operation pin 54 is connected to the illumination panel 50. 0 is arranged in a position opposite the first part 41 of the hook 40 when the illumination panel 50 is in the stored state, and as the illumination panel 50 slides from the stored state within the storage recess 20 towards the board side connector part 28 side, the rotation operation pin 54 abuts against the first part 41 of the hook 40 and pushes up the first part 41 from below, causing the hook 40 to rotate around the rotation axis 45, and when the illumination panel 50 is in the attached state, the second part 43 is configured to support from below a stepped first step part (an example of a locked part) 56 provided on the exterior surface of the main body part 51 and lock it.

[0055] According to the above configuration, when the illumination panel 50 is removed from the trim board 11, the hooks 40 are arranged along the rear wall 25 and are therefore difficult for occupants to see, improving the design of the trim board 11. Furthermore, when the illumination panel 50 is attached, the hooks 40 are arranged in a position that is not visible to occupants, so the design is not impaired. Furthermore, since the hooks 40 are arranged in a direction that follows the plate surface of the trim board 11 as a whole, they can fulfill a reinforcing function against impacts during a side collision and loads from above.

[0056] In addition, when the illumination panel 50 is not placed in the storage recess 20, the hook 40 has a third part 44 that is bent and connected to the lower end of the second part 43 and extends toward the inside of the storage recess 20, and the third part 44 is configured to engage with a second step part (an example of a second engaging part) 57 provided on the exterior surface of the main body part 51 by supporting it from below when the illumination panel 50 is in an installed state.

[0057] According to the above configuration, the hook 40 can hold the illumination panel 50 more stably than in a configuration in which the hook 40 does not have the third portion 44.

[0058] A guide hole 42 is formed in the first part 41 of the hook 40, penetrating its plate surface, and an arc-shaped guide portion 30 is provided on the upper surface of the upper wall 22 of the trim board 11, which is inserted into the guide hole 42 and guides the rotational position of the first part 41.

[0059] Furthermore, the guide portion 30 may be provided with a lock portion 31 for locking the orientation of the first portion 41 when the illumination panel 50 is in the attached state.

[0060] According to the above configuration, the locking portion 31 maintains the illumination panel 50 attached to the trim board 11, and prevents the panel-side connector portion 53 from unintentionally detaching from the board-side connector portion 28.

[0061] In addition, the storage recess 20 is located adjacent to the side end of the door trim 10, and the locked state of the locking section 31 can be released by inserting an unlocking pin 60 through an unlocking hole 16 located at the side end of the door trim 10.

[0062] Furthermore, a cover portion 52 that covers the storage recess 20 from the inside of the room when the illumination panel 50 is installed is provided on the surface of the main body 51 of the illumination panel 50 that faces the interior of the room. This configuration further improves the design when the illumination panel 50 is installed in the storage recess 20.

[0063] <Embodiment 2> Next, a second embodiment will be described with reference to Figures 12 to 14. Note that only configurations different from the first embodiment will be described below, and configurations similar to those in the first embodiment will be given the same reference numerals, and redundant description will be omitted.

[0064] The door trim 110 (trim board 11) of this embodiment differs from the first embodiment in that a recess 122A provided in an upper wall 122 of the accommodation recess 120 is a groove-like elongated groove extending in the vehicle longitudinal direction. The board-side connector 128 is configured such that a terminal 128A is exposed in a part of the groove-like recess 122A.

[0065] On the other hand, the illumination panel 150 has a rising portion 151A that rises from the upper surface of the main body 151 at a position that faces the recessed portion 122A when the illumination panel 150 is accommodated in the accommodating recess 120. The rising portion 151A extends from the front end of the main body 151 to a position that faces the tip of the first portion 41 of the hook 40 when the illumination panel 150 is accommodated in the accommodating recess 120 (see FIG. 13). The dimensions of this rising portion 151A are set so that the entire portion can be accommodated within the recessed portion 122A. The panel-side connector portion 153 is provided on this rising portion 151A at a position that faces the board-side connector portion 128 (terminal 128A). The panel side connector portion 153 has a box-shaped recessed shape extending downward from the upper surface of the rising portion 151A, and inside it is arranged a panel side terminal (not shown) that can be connected to the terminal 128A of the board side connector portion 128.

[0066] When attaching the illumination panel 150 of this embodiment to the trim board 11, the illumination panel 150 is accommodated in the accommodation recess 120 with the panel-side connector portion 153 facing upward, and then slid upward. Then, the entire rising portion 151A is fitted into the groove-shaped recess 122A, and the board-side connector portion 128 (terminal 128A) is inserted into the panel-side connector portion 153 recessed from the top surface of the rising portion 151A, establishing an electrical connection.

[0067] As the illumination panel 150 is slid from the storage state to the attached state in this manner, as shown in FIGS. 13 and 14 , the rear end (an example of a rotation operating portion) 154 of the rising portion 151A pushes the first portion 41 of the hook 40 upward, causing the entire hook 40 to rotate around the rotation shaft 45. As a result, the second portion 43 of the hook 40 supports the first step portion 56 of the illumination panel 150 from below, and the third portion 44 supports the second step portion 57 from below, thereby engaging the main body portion 151. In other words, the second portion 43 and the third portion 44 of the hook 40 engage the main body portion 151 from different directions. The recessed portion 122A is formed with a relief hole 122B to allow the first portion 41 of the hook 40 to rotate.

[0068] According to this embodiment, in addition to the effects of embodiment 1, the panel side connector portion 153 and the rotation operation portion (rear end 154) provided on the illumination panel 150 do not protrude individually from the main body portion 151, but are connected together as a single unit, making the structure stronger and making the illumination panel 150 easier to handle.

[0070] (1) The main body of the electrical component may be arranged to protrude from the interior surface of the trim board when placed in the accommodating recess.

[0071] (2) The locking member and its locking structure are not limited to the above embodiment. For example, in the above embodiment, the second portion 43 and the third portion 44 of the hook 40 are bent at a right angle, but they may be bent at an acute or obtuse angle. Also, in the above embodiment, a substantially U-shaped hook 40 is illustrated, but for example, an L-shaped locking member without the third portion 44 may also be used.

[0072] (3) The male and female connectors may be reversed. Even in this case, it is sufficient that the board-side connector portion is recessed from the inner surface of the recess.

[0073] (4) The shapes of the accommodating recess and the electrical components are not limited to those in the above embodiment.

[0074] (5) In the above embodiment, one locking member is provided for one electrical component. However, a plurality of locking members may be provided for one electrical component.
