Description

Technical Field

[0001] The present disclosure relates to a sun visor module for a vehicle. Background Art

[0002] For example, a vehicle sun visor is installed at the front part of the ceiling of a vehicle. The vehicle sun visor is used to prevent light from outside the vehicle from directly shining into the eyes of passengers in the vehicle interior. The vehicle sun visor is sometimes arranged adjacent to a ceiling component that forms at least a part of the ceiling. In this case, the vehicle sun visor has a plate body that can rotate between a use position and a retracted position relative to the ceiling component.

[0003] In addition, a mirror that a passenger can use as a makeup mirror is sometimes installed on the plate body. In such a case, in order to be able to use the mirror even at night, for example, as described in Japanese Patent No. 6763789, a vehicle sun visor with a lighting device built therein is known. The lighting device irradiates light into the vehicle interior. In addition, in the above publication, an inductive switch is built in the vehicle sun visor. The inductive switch turns on the lighting device by becoming in the on state and turns off the lighting device by becoming in the off state.

[0004] The lighting device is electrically connected to the vehicle power supply via the inductive switch. And, when the inductive switch becomes in the on state, the lighting device is supplied with power from the vehicle power supply and lights up, and when the inductive switch becomes in the off state, the supply of power from the vehicle power supply to the lighting device is cut off and the lighting device goes out. Summary of the Invention

[0005] Problems to be Solved by the Invention

[0006] As in the above publication, when the lighting device and the inductive switch are built in the vehicle sun visor, for example, it is necessary to introduce wiring from the ceiling of the vehicle to the plate body of the vehicle sun visor and electrically connect it to the lighting device via the inductive switch. Therefore, the conduction path from the vehicle power supply to the lighting device becomes longer, and it is possible that the supply of power from the vehicle power supply to the lighting device via the wiring becomes unstable. In addition, in the vehicle sun visor, only a part of it is connected to the ceiling. Therefore, when introducing the wiring from the ceiling of the vehicle to the plate body, it is necessary to introduce the wiring from a restricted part of the vehicle sun visor connected to the ceiling to the plate body. As a result, the structure of the vehicle sun visor becomes complicated. Thus, it is desired to be able to stably supply power to the lighting device, simplify the configuration of the vehicle sun visor, and make it easy to turn on or off the lighting device.

[0007] Means for Solving the Problems

[0008] In one aspect of the present disclosure, a sun visor module for a vehicle is provided. The sun visor module for a vehicle includes: a ceiling forming portion that forms at least a part of the ceiling of the vehicle; and a vehicle sun visor that is disposed adjacent to the ceiling forming portion. The vehicle sun visor has: a plate body that is configured to be rotatable between a use position and a retracted position relative to the ceiling forming portion; and a mirror that is mounted on the plate body. The ceiling forming portion includes: a lighting device that is configured to irradiate light into the vehicle interior; and a proximity switch that is configured to turn on the lighting device when it is in the on state and turn off the lighting device when it is in the off state. The vehicle sun visor has a magnet that is configured to be able to switch the proximity switch between the on state and the off state. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Hereinafter, according to Figures 1 to 5, an embodiment of a vehicle sun visor module will be described.

[0030] (Overall Structure of Vehicle Sun Visor Module 10)

[0031] As Figure 1 and Figure 2 shown, the vehicle sun visor module 10 includes a decorative part 11 as a ceiling component part and a vehicle sun visor 20. The vehicle sun visor 20 is used to prevent light from outside the vehicle from directly shining into the eyes of passengers in the vehicle interior. Regarding the vehicle sun visor module 10, the decorative part 11 is fixed to the vehicle ceiling by fastening members such as bolts, and thus is installed in the front part of the vehicle ceiling. The vehicle sun visor 20 is arranged adjacent to the decorative part 11.

[0032] In this specification, the directions indicated by terms such as "front", "rear", "upper", "lower", "left", and "right" are defined based on the vehicle for the convenience of explanation, but are not limited thereto.

[0033] (Structure of Decorative Part 11)

[0034] As Figure 2 shown, the decorative part 11 has a decorative main body 12. The decorative main body 12 is made of a resin material. The decorative main body 12 is plate-shaped and forms a part of the ceiling. Therefore, the decorative part 11 forms a part of the front part of the vehicle ceiling. The decorative part 11 has a hook 13. The hook 13 protrudes downward from the decorative main body 12. The hook 13 is made of a resin material.

[0035] (Regarding Lighting Device 15)

[0036] As Figure 2 and Figure 3 shown, the decorative part 11 is provided with a lighting device 15. The lighting device 15 irradiates light into the vehicle interior. An emission hole 12h is formed in the decorative main body 12, and the light irradiated by the lighting device 15 is emitted from the emission hole 12h. The lighting device 15 is installed on the decorative main body 12 in a state where the light irradiated from the lighting device 15 can pass through the emission hole 12h and be emitted into the vehicle interior.

[0037] As Figure 3 shown, the lighting device 15 is installed on the back surface of the decorative main body 12 on the side opposite to the vehicle interior by fastening members such as bolts, for example. Therefore, the lighting device 15 is integrally formed with the decorative part 11. In addition, the lighting device 15 is, for example, an LED lighting module composed of an LED chip as a lamp body and a control substrate for controlling the driving of the LED chip, etc.

[0038] (Structure of First Inductive Switch 31)

[0039] As Figure 2 andFigure 4 As shown, the decoration unit 11 is provided with an inductive switch. The inductive switch turns on the lighting device 15 when it becomes conductive and turns off the lighting device 15 when it becomes non-conductive. The inductive switch includes a first inductive switch 31. The first inductive switch 31 turns on the lighting device 15 when it becomes conductive and turns off the lighting device 15 when it becomes non-conductive. In addition, in Figure 2 , a switching circuit of the first inductive switch 31 is schematically shown. In Figure 4 , a housing that houses the switching circuit of the first inductive switch 31 and the like is schematically shown. The first inductive switch 31 is a normally open reed switch that becomes conductive when a magnetic field acts and becomes non-conductive when no magnetic field acts. The first inductive switch 31 is mounted on the decoration main body 12. Therefore, the first inductive switch 31 is integrally formed with the decoration unit 11.

[0040] (Configuration of the second inductive switch 32)

[0041] As Figure 2 and Figure 3 shown, the inductive switch includes a second inductive switch 32. The second inductive switch 32 turns on the lighting device 15 when it becomes conductive and turns off the lighting device 15 when it becomes non-conductive. In addition, in Figure 2 , a switching circuit of the second inductive switch 32 is schematically shown. In Figure 3 , a housing that houses the switching circuit of the second inductive switch 32 and the like is schematically shown. The second inductive switch 32 is a normally closed reed switch that becomes non-conductive when a magnetic field acts and becomes conductive when no magnetic field acts. The second inductive switch 32 is mounted on the decoration main body 12. Therefore, the second inductive switch 32 is integrally formed with the decoration unit 11.

[0042] (Regarding the conductive path)

[0043] As Figure 2 shown, the vehicle sun visor module 10 is provided with a wiring 33. The wiring 33 supplies power from the vehicle power supply 34 to the lighting device 15. Therefore, the lighting device 15 is electrically connected to the vehicle power supply 34 via the wiring 33. The wiring 33 is electrically connected to the ground terminal from the vehicle power supply 34 via the lighting device 15, the second inductive switch 32, and the first inductive switch 31. The wiring 33 is laid on the back surface, for example, in a state where it is clamped to the back surface of the decoration main body 12 on the side opposite to the interior of the vehicle.

[0044] Also, when both the first inductive switch 31 and the second inductive switch 32 are in the on state, the conduction path from the power supply 34 to the ground terminal is conducted. Thereby, power is supplied from the power supply 34 to the lighting device 15, and the lighting device 15 is lit. On the other hand, when at least one of the first inductive switch 31 and the second inductive switch 32 is in the off state, the conduction path from the power supply 34 to the ground terminal is cut off. Thereby, the supply of power from the power supply 34 to the lighting device 15 is cut off, and the lighting device 15 is turned off.

[0045] (Configuration of the vehicle sun visor 20)

[0046] The vehicle sun visor 20 includes a plate body 21, a mirror 22, and a cover body 23. In addition, Figure 2 Hereafter, the relationship among the plate body 21, the mirror 22, and the cover body 23 is schematically shown. The plate body 21 is made of a resin material. The plate body 21 is formed by overlapping and bonding a pair of shell-shaped half-divided bodies. The plate body 21 is in a flat plate shape. The plate body 21 forms a rectangle when viewed from above. The plate body 21 is arranged in the decorative portion 11 such that the long side direction of the plate body 21 coincides with the vehicle width direction.

[0047] The vehicle sun visor 20 has an arm 24. The arm 24 is in a substantially L-shaped bent cylindrical shape. One end of the arm 24 is supported by the decorative portion 11 via a bracket 25. The other end of the arm 24 is inserted into a bearing portion (not shown) of the plate body 21.

[0048] As Figure 3 shown, the plate body 21 can rotate about a straight line along the vehicle width direction with the arm 24 as the rotation center relative to the decorative portion 11. The plate body 21 can rotate between a use position and a retracted position relative to the decorative portion 11. In addition, Figure 1 and Figure 3 the state where the plate body 21 is located at the use position is shown by a solid line, and the state where the plate body 21 is located at the retracted position is shown by a double-dot dash line. And when the plate body 21 is located at the use position, the plate body 21 prevents light from outside the vehicle from directly irradiating the eyes of the passengers in the vehicle interior.

[0049] As Figure 1 and Figure 2 shown, a cutout 21a is formed at the edge portion of the plate body 21. In addition, the vehicle sun visor 20 has a cylindrical locking portion 26. The locking portion 26 is provided on the plate body 21 such that the cutout 21a cuts across in the long side direction of the plate body 21. The locking portion 26 can be locked to the hook 13. In the state where the locking portion 26 is locked to the hook 13, the plate body 21 can rotate about a straight line along the vehicle width direction with the arm 24 as the rotation center relative to the decorative portion 11.

[0050] As Figure 5As shown, a rectangular opening 21h is formed in the plate body 21. The opening 21h is a substantially square hole when viewed from above. In addition, the plate body 21 has a sliding mechanism 27 communicating with the opening 21h. The sliding mechanism 27 is constituted by, for example, a track extending in the longitudinal direction of the plate body 21 from the opening 21h. The sliding mechanism 27 is provided inside the plate body 21.

[0051] A mirror 22 is mounted on the plate body 21. The mirror 22 is flat. The mirror 22 is mounted on the plate body 21 in a state where the thickness direction of the mirror 22 coincides with the thickness direction of the plate body 21. The mirror 22 is mounted on the plate body 21 in a state of being embedded in the opening 21h.

[0052] As Figure 2 and Figure 5 shown, the cover body 23 is substantially square plate-shaped. The cover body 23 is made of a resin material. The cover body 23 is provided so as to be slidable relative to the plate body 21 through the sliding mechanism 27. The cover body 23 can move along the sliding mechanism 27 and can project from and be buried in the plate body 21. The cover body 23 moves from the inside of the plate body 21 to a position overlapping the opening 21h to cover the mirror 22. In addition, the cover body 23 is buried in the inside of the plate body 21 from the opening 21h to expose the mirror 22. Therefore, the cover body 23 can move relative to the plate body 21 between an open position where the mirror 22 is exposed and a closed position where the mirror 22 is covered. In addition, the sliding mechanism 27 is configured to be able to hold the cover body 23 at the open position and the closed position, respectively.

[0053] (Regarding the first magnet 41)

[0054] The vehicle sun visor 20 includes a magnet capable of switching an inductive switch to an on state and an off state. The magnet includes a first magnet 41. In addition, after Figure 2 that, the first magnet 41 is schematically shown by dot hatching. The first magnet 41 is provided on the cover body 23. The first magnet 41 is provided at the upper edge portion of the cover body 23 in a state where the plate body 21 is in the use position. The first magnet 41 generates a magnetic field. The first magnet 41 is a magnet that can cooperate with a third magnet 43 described later to switch the first inductive switch 31 to an on state and an off state. Specifically, the first magnet 41 sets the first inductive switch 31 to the on state when the cover body 23 is in the open position, and sets the first inductive switch 31 to the off state when the cover body 23 is in the closed position.

[0055] (Regarding the second magnet 42)

[0056] As Figure 2 and Figure 3 shown, the magnet includes a second magnet 42. In addition, in Figure 2Thereafter, the second magnet 42 is schematically shown by dot hatching. The second magnet 42 is built into the plate body 21. In a state where the plate body 21 is in the use position, the second magnet 42 is located between the opening 21h and the decoration part 11. The second magnet 42 is provided at a position corresponding to the second inductive switch 32 in the plate body 21. That is, when the plate body 21 is in the retracted position, the second magnet 42 is provided at a position opposed to the second inductive switch 32 in the vertical direction. The second magnet 42 generates a magnetic field. The second magnet 42 is a magnet capable of switching the second inductive switch 32 between the on state and the off state. Specifically, the second magnet 42 sets the second inductive switch 32 to the on state when the plate body 21 is in the use position, and sets the second inductive switch 32 to the off state when the plate body 21 is in the retracted position.

[0057] (Regarding the relationship between the first magnet 41 and the second magnet 42 and the lighting device 15)

[0058] The lighting device 15 is lit when both the first inductive switch 31 and the second inductive switch 32 are in the on state, and is extinguished when at least one of the first inductive switch 31 and the second inductive switch 32 is in the off state.

[0059] (Regarding the third magnet 43)

[0060] As Figure 2 and Figure 5 shown, the magnet includes the third magnet 43. In addition, thereafter, Figure 2 the third magnet 43 is schematically shown by dot hatching. The third magnet 43 is built into the plate body 21. The third magnet 43 is located at the position of the upper edge portion of the plate body 21 in a state where the plate body 21 is in the use position. The third magnet 43 generates a magnetic field that sets the first inductive switch 31 to the on state. The direction of the magnetic field generated by the third magnet 43 is opposite to the direction of the magnetic field generated by the first magnet 41.

[0061] (Regarding the relationship between the first magnet 41 and the third magnet 43)

[0062] The first magnet 41 is disposed on the plate main body 21 such that it is in the position closest to the third magnet 43 when the lid body 23 is in the closed position. Also, when the lid body 23 is in the open position, the first magnet 41 moves away from the magnetic field generated by the third magnet 43 and no longer cancels the magnetic field generated by the third magnet 43. As a result, the first inductive switch 31 is turned on by the magnetic field generated by the third magnet 43. In other words, when the lid body 23 is in the open position, the first magnet 41 moves away from the magnetic field generated by the third magnet 43 to turn on the first inductive switch 31. On the other hand, when the lid body 23 is in the closed position, the first magnet 41 cancels the magnetic field generated by the third magnet 43. As a result, the first inductive switch 31 is turned off. In other words, when the lid body 23 is in the closed position, the first magnet 41 cancels the magnetic field generated by the third magnet 43 to turn off the first inductive switch 31.

[0063] (Function)

[0064] Next, the function of the present embodiment will be described.

[0065] For example, consider a case where the plate main body 21 is in the retracted position and the lid body 23 is in the closed position. At this time, the first inductive switch 31 is turned off because the first magnet 41 cancels the magnetic field generated by the third magnet 43, and the second inductive switch 32 is turned off by the magnetic field of the second magnet 42. As a result, the lighting device 15 is in the extinguished state.

[0066] From this state, for example, when the plate main body 21 is in the use position, the second magnet 42 moves away from the second inductive switch 32, and the magnetic field of the second magnet 42 no longer acts on the second inductive switch 32. As a result, the second inductive switch 32 is turned on.

[0067] Next, when the lid body 23 is in the open position, the first magnet 41 moves away from the magnetic field generated by the third magnet 43, and the magnetic field of the third magnet 43 acts on the first inductive switch 31. As a result, the first inductive switch 31 is turned on. As a result, the lighting device 15 is lit because both the first inductive switch 31 and the second inductive switch 32 are turned on.

[0068] On the other hand, consider a case where the plate main body 21 is in the use position and the lid body 23 is in the open position. From this state, for example, when the lid body 23 is in the closed position, the first magnet 41 approaches the third magnet 43, and the magnetic field generated by the first magnet 41 cancels the magnetic field generated by the third magnet 43. As a result, the magnetic field of the third magnet 43 no longer acts on the first inductive switch 31, and the first inductive switch 31 is turned off. As a result, the lighting device 15 is extinguished.

[0069] In addition, consider a situation where the plate body 21 is in the use position and the lid body 23 is in the open position. From this state, for example, with the lid body 23 still in the open position, the plate body 21 is moved to the retracted position. Then, the second magnet 42 approaches the second inductive switch 32, and the magnetic field of the second magnet 42 acts on the second inductive switch 32. As a result, the second inductive switch 32 becomes the off state. Consequently, the lighting device 15 is turned off.

[0070] (Effect)

[0071] The above-described embodiment can achieve the following effects.

[0072] (1) The decorative portion 11 includes the lighting device 15, the first inductive switch 31, and the second inductive switch 32. Therefore, unlike the prior art, for example, there is no need to route wiring from the vehicle ceiling to the plate body 21 of the vehicle sun visor 20 and electrically connect the wiring to the lighting device 15. Thus, since the conductive path from the vehicle power supply 34 to the lighting device 15 can be set short, stable power supply to the lighting device 15 can be performed.

[0073] Moreover, the vehicle sun visor 20 has the first magnet 41 and the third magnet 43 that can switch the first inductive switch 31 between the on state and the off state, and the second magnet 42 that can switch the second inductive switch 32 between the on state and the off state. Therefore, by providing only the first magnet 41, the second magnet 42, and the third magnet 43 on the vehicle sun visor 20, the first inductive switch 31 can be switched between the on state and the off state, and the second inductive switch 32 can be switched between the on state and the off state. Thus, while the configuration of the vehicle sun visor 20 can be made simple, the lighting device 15 can be easily turned on or off. As described above, stable power supply to the lighting device 15 can be performed, and while the configuration of the vehicle sun visor 20 can be made simple, the lighting device 15 can be easily turned on or off.

[0074] (2) When the lid body 23 is in the open position, the first magnet 41 sets the first inductive switch 31 to the on state, and the lighting device 15 can be turned on. In addition, when the lid body 23 is moved to the closed position, the first magnet 41 sets the first inductive switch 31 to the off state, and the lighting device 15 can be turned off. In this way, by changing the position of the lid body 23 relative to the plate body 21, the lighting device 15 can be easily turned on or off.

[0075] (3) The lighting device 15 is turned on and illuminated when both the first inductive switch 31 and the second inductive switch 32 are in the on state. That is, the lighting device 15 is illuminated only when the plate body 21 is in the use position and the cover body 23 is in the open position. Therefore, when the passenger uses the mirror 22 as a makeup mirror, the lighting device 15 can be illuminated.

[0076] In addition, the lighting device 15 is turned off when at least one of the first inductive switch 31 and the second inductive switch 32 is in the off state. Therefore, even if the cover body 23 is not in the closed position, for example, the lighting device 15 can be turned off by moving the plate body 21 to the retracted position. Therefore, it is possible to avoid forgetting to turn off the lighting device 15 and achieve energy conservation.

[0077] (4) The first magnet 41 is provided on the cover body 23. According to this structure, since the first magnet 41 moves integrally with the cover body 23, the first inductive switch 31 can be switched between the on state and the off state in conjunction with the movement of the cover body 23 relative to the plate body 21.

[0078] (5) The magnet further includes a third magnet 43 that generates a magnetic field for setting the first inductive switch 31 to the on state. When the cover body 23 is in the open position, the first magnet 41 moves away from the magnetic field generated by the third magnet 43 and sets the first inductive switch 31 to the on state. On the other hand, when the cover body 23 is in the closed position, the first magnet 41 cancels the magnetic field generated by the third magnet 43 and sets the first inductive switch 31 to the off state.

[0079] According to this structure, even if the first inductive switch 31 is arranged within the range of the magnetic field generated by the first magnet 41, by providing the third magnet 43 on the plate body 21, the first inductive switch 31 can be switched between the on state and the off state. Therefore, it is possible to increase the degree of freedom in the arrangement of the first inductive switch 31 relative to the decorative portion 11 and the arrangement of the first magnet 41 relative to the vehicle sun visor 20.

[0080] (6) Since the first inductive switch 31 and the second inductive switch 32 are switched between the on state and the off state according to the presence or absence of the magnetic field action, it is difficult to generate an operating sound such as that of a mechanical switch. Therefore, the quietness can be improved.

[0081] (7) Since the first inductive switch 31 and the second inductive switch 32 are switched between the on state and the off state according to the presence or absence of the magnetic field action, a structure can be designed to minimize the number of switch contacts as much as possible. Therefore, the structure can be simplified.

[0082] (Variant example)

[0083] In addition, the above-mentioned embodiment can be modified and implemented as follows. The above-mentioned embodiment and the following modified examples can be implemented in combination with each other within the scope that there is no technical contradiction.

[0084] ·like Figure 6 as well as Figure 7 As shown, the first magnet 41 can be set at a position corresponding to the first inductive switch 31 in the plate body 21. That is, the first magnet 41 can be set at a position opposite to the first inductive switch 31 in the up-down direction of the vehicle when the plate body 21 is in the retracted position. The plate body 21 has a spring portion 51. The spring portion 51 is a compression spring that presses the first magnet 41 in a direction away from the first inductive switch 31. The spring portion 51 is built into the plate body 21. The plate body 21 has a supporting member 52 that supports the first magnet 41. The supporting member 52 has a columnar supporting portion 52a and a plate-shaped flange portion 52b. The supporting portion 52a has a first end and a second end on the side opposite to the first end. The flange portion 52b protrudes from the first end of the supporting portion 52a. The support member 52 is provided on the plate body 21 in a state where the axial direction of the support portion 52a is orthogonal to the long side direction of the plate body 21 and also orthogonal to the thickness direction of the plate body 21. The first magnet 41 is mounted on the second end of the support portion 52a. In addition, the plate body 21 has a spring support portion 53 that supports the biasing portion 51. The spring support portion 53 is cylindrical. The spring support portion 53 is built into the plate body 21. The second end of the support portion 52a passes through the inner side of the spring support portion 53. The biasing portion 51 is between the spring support portion 53 and the flange portion 52b. And, the biasing portion 51 biases the flange portion 52b in a direction away from the spring support portion 53. As a result, the biasing portion 51 biases the first magnet 41 in a direction away from the first inductive switch 31. When the cover body 23 moves toward the open position, the cover body 23 can abut against the flange portion 52b.

[0085] like Figure 7 As shown, when the cover body 23 moves toward the open position, the cover body 23 abuts against the flange portion 52b, and the cover body 23 overcomes the spring force of the spring portion 51 and presses the support member 52 toward the first inductive switch 31. As a result, the first magnet 41 approaches the first inductive switch 31, and the first inductive switch 31 becomes the on state. In this way, as the cover body 23 moves toward the open position, the cover body 23 overcomes the spring force of the spring portion 51 and presses the first magnet 41. Furthermore, the first magnet 41 approaches the first inductive switch 31, so that the first inductive switch 31 becomes the on state.

[0086] like Figure 6As shown, when the cover body 23 is in the closed position, the support member 52 is restored to its original position before being pressed by the cover body 23 by the elastic force of the elastic pressing portion 51. Thus, the first magnet 41 moves to its original position before being pressed by the cover body 23, that is, separates from the first inductive switch 31, and the first inductive switch 31 becomes in an off state. In this way, the lighting device 15 can be turned on or off.

[0087] According to this structure, even if the first magnet 41 is not provided on the cover body 23, the first inductive switch 31 can be switched between the on state and the off state by the first magnet 41. Therefore, the structure of the cover body 23 can be simplified.

[0088] · As Figure 8 and Figure 9 shown, the first inductive switch 31 can be built into the hook 13, for example. In this case, the hook 13 is formed in a hollow shape, and the first inductive switch 31 is housed inside the hook 13. And, as Figure 9 shown, when the cover body 23 is in the open position, the magnetic field of the first magnet 41 acts on the first inductive switch 31, and the first inductive switch 31 becomes in an on state. On the other hand, as Figure 8 shown, when the cover body 23 is in the closed position, the magnetic field of the first magnet 41 no longer acts on the first inductive switch 31, and the first inductive switch 31 becomes in an off state. In this way, the lighting device 15 can be turned on or off.

[0089] · As Figure 10 and Figure 11 shown, the vehicle sun visor 20 can be configured without the cover body 23. And the vehicle sun visor 20 can have, for example, a mechanical switch 60 that moves the first magnet 41 in a direction approaching or leaving the first inductive switch 31. The vehicle sun visor 20 has, for example, the elastic pressing portion 51, the support member 52, and the spring support portion 53 that have been described in the embodiments shown in Figure 6 and Figure 7 above.

[0090] A guide groove 61 for guiding the mechanical switch 60 is formed in the plate main body 21. The mechanical switch 60 has: an operation portion 62 that can move along the guide groove 61; and a contact portion 63 that can move integrally with the operation portion 62 and abuts against the flange portion 52b of the support member 52. The operation portion 62 moves along the guide groove 61, so that it can be switched to a first switching position where the first inductive switch 31 is set to an off state and a second switching position where the first inductive switch 31 is set to an on state.

[0091] As Figure 11As shown, when the operating portion 62 of the mechanical switch 60 moves from the first switching position toward the second switching position, the abutting portion 63 presses the first magnet 41 against the elastic force of the elastic pressing portion 51. Specifically, when the operating portion 62 moves from the first switching position toward the second switching position, the abutting portion 63 abuts against the flange portion 52b, and the abutting portion 63 presses the support member 52 toward the first inductive switch 31 against the elastic force of the elastic pressing portion 51. As a result, the first magnet 41 approaches the first inductive switch 31, and the first inductive switch 31 becomes in an on state.

[0092] As Figure 10 shown, when the operating portion 62 of the mechanical switch 60 is at the first switching position, the support member 52 is restored to its original position before being pressed by the abutting portion 63 by the elastic force of the elastic pressing portion 51. As a result, the first magnet 41 moves to its original position before being pressed by the abutting portion 63, that is, separates from the first inductive switch 31, and the first inductive switch 31 becomes in an off state. Therefore, the first magnet 41 is operated by the mechanical switch 60, and thus the first inductive switch 31 can be switched between the on state and the off state. In this way, the lighting device 15 can be turned on or off.

[0093] According to such a configuration, it is applicable to the following situation: for example, the vehicle sun visor 20 does not have a cover body 23 that can move between an open position where the mirror 22 is exposed and a closed position where the mirror 22 is covered with respect to the plate main body 21.

[0094] · As Figure 12 and Figure 13 shown, the vehicle sun visor module 10 may also adopt a configuration in which each has a magnet 71 and an inductive switch 72. The decorative portion 11 has an inductive switch 72. The vehicle sun visor 20 has a magnet 71. The magnet 71 is, for example, a quadrangular column. The magnet 71 is magnetized along the axial direction of the magnet 71. In the axial direction of the magnet 71, the first end 71a of the magnet 71 is magnetized as an N pole, for example, and the second end 71b on the side opposite to the first end 71a of the magnet 71 is magnetized as an S pole, for example. In addition, the magnet 71 may adopt a configuration in which the first end 71a of the magnet 71 is magnetized as an S pole and the second end 71b of the magnet 71 is magnetized as an N pole.

[0095] The vehicle sun visor module 10 has a magnet switch 70. The magnet switch 70 holds the magnet 71. The magnet switch 70 is built in the plate main body 21. Therefore, the plate main body 21 has the magnet switch 70. The magnet switch 70 is provided at a position in the plate main body 21 corresponding to the inductive switch 72. Therefore, the magnet 71 is provided at a position in the plate main body 21 corresponding to the inductive switch 72. That is, when the plate main body 21 is in the retracted position, the magnet 71 is provided at a position opposed to the inductive switch 72 in the vertical direction.

[0096] As Figure 14 and Figure 15 shown, the magnet switch 70 has a housing 73, a moving body 74, and a biasing portion 75. Therefore, the plate body 21 has the biasing portion 75. The housing 73 is in the shape of a square cylinder. The housing 73 is made of a resin material. The housing 73 has an insertion through-hole 73a. The insertion through-hole 73a is in the shape of a square hole.

[0097] The moving body 74 is in the shape of a four-sided plate. The moving body 74 is made of a resin material. The moving body 74 has a support portion 76. The support portion 76 is in the shape of a four-sided column. The support portion 76 can be inserted into the inside of the insertion through-hole 73a of the housing 73. And, the outer surface of the support portion 76 contacts the inner surface of the insertion through-hole 73a, thereby suppressing the moving body 74 from rotating relative to the housing 73 with the axis of the insertion through-hole 73a as the rotation center.

[0098] A rectangular hole-shaped storage recess 76a is formed in the support portion 76. The long side direction of the storage recess 76a is aligned with the axial direction of the support portion 76. A magnet 71 is stored in the storage recess 76a. The magnet 71 is held by the support portion 76 in a state of being stored in the storage recess 76a. The magnet 71 is stored in the storage recess 76a in a state where the axial direction of the magnet 71 is aligned with the long side direction of the storage recess 76a.

[0099] The moving body 74 has a protruding surface 74a where the support portion 76 protrudes. The protruding surface 74a is, for example, in the shape of a flat surface. The protruding surface 74a extends in a direction orthogonal to the axial direction of the support portion 76. In addition, the shape of the protruding surface 74a is not limited to the flat surface shape, and the shape of the protruding surface 74a can be appropriately changed. In addition, the moving body 74 has a curved surface 74b. The curved surface 74b is the surface of the moving body 74 on the side opposite to the protruding surface 74a. The curved surface 74b gradually bends and inclines as it moves from the first side surface 74c of the moving body 74 toward the second side surface 74d. The curved surface 74b extends toward the second side surface 74d while gradually separating from the protruding surface 74a as it separates from the first side surface 74c. The curved surface 74b is a surface that protrudes with respect to the protruding surface 74a.

[0100] The biasing portion 75 is a compression spring. The biasing portion 75 is interposed between the housing 73 and the moving body 74. The biasing portion 75 biases the moving body 74 in a direction away from the housing 73.

[0101] As Figure 12 and Figure 16As shown, in the state where the plate main body 21 is in the use position, the curved surface 74b of the moving body 74 is at a position separated from the housing 73 and the inductive switch 72. The pressing portion 75 presses the moving body 74 in a direction away from the inductive switch 72. As a result, the pressing portion 75 presses the magnet 71 in a direction away from the inductive switch 72. In addition, the first side surface 74c of the moving body 74 is at a position closer to the mirror 22 than the second side surface 74d of the moving body 74. The moving direction of the moving body 74 is a direction orthogonal to the direction in which the cover body 23 slides along the sliding mechanism 27. As Figure 12 and Figure 13 shown, in the state where the plate main body 21 is in the use position, the moving direction of the moving body 74 is a direction approaching or leaving the inductive switch 72.

[0102] As Figure 16 and Figure 17 shown, when the cover body 23 moves toward the open position, the cover body 23 can abut against the curved surface 74b of the moving body 74. When the cover body 23 moves toward the open position, the cover body 23 abuts against the curved surface 74b of the moving body 74, and the cover body 23 presses the moving body 74 toward the inductive switch 72 against the pressing force of the pressing portion 75. As a result, the magnet 71 approaches the inductive switch 72.

[0103] As Figure 18 shown, the inductive switch 72 is a normally open magnetic reed switch that becomes on when a magnetic field acts and becomes off when no magnetic field acts. Specifically, the inductive switch 72 has a pair of guide pieces 72a. Each guide piece 72a has a contact 72s. And the inductive switch 72 becomes on when the contacts 72s of the respective guide pieces 72a come into contact with each other. On the other hand, the inductive switch 72 becomes off when the contacts 72s of the respective guide pieces 72a are separated from each other.

[0104] Figure 18 Shows the positional relationship between the magnet 71 and the inductive switch 72 when the plate main body 21 is in the use position. As Figure 18 shown, in the state where the plate main body 21 is in the use position, the magnet 71 is disposed at a position corresponding to one of the pair of guide pieces 72a. In the state where the plate main body 21 is in the use position, the axis L1 of the magnet 71 intersects a part of the inductive switch 72. Specifically, the axis L1 of the magnet 71 intersects one of the pair of guide pieces 72a.

[0105] And, for example, assume that in the state where the plate main body 21 is in the use position, the moving body 74 is pressed by the cover body 23. Then, as Figure 18As shown, the magnet 71 approaches one of a pair of guide pieces 72a. At this time, the first end 71a of the magnet 71 is positioned closer to the inductive switch 72 than the second end 71b of the magnet 71. Also, the magnet 71 is positioned close to one of the pair of guide pieces 72a, i.e., one of the guide pieces 72a. As a result, one of the pair of guide pieces 72a is magnetized, and one of the guide pieces 72a of the pair of guide pieces 72a attracts the other guide piece 72a by magnetic force. Consequently, the contacts 72s of the respective guide pieces 72a come into contact with each other, and the inductive switch 72 becomes in an on state.

[0106] Therefore, in a state where the plate main body 21 is in the use position, as the cover body 23 moves toward the open position, the cover body 23 presses the magnet 71 against the elastic force of the elastic pressing portion 75. And the magnet 71 approaches the inductive switch 72, so that the inductive switch 72 becomes in an on state. On the other hand, when the cover body 23 is in the closed position, due to the elastic force of the elastic pressing portion 75, the magnet 71 moves to its original position before being pressed by the cover body 23. And the magnet 71 separates from the inductive switch 72, so that the inductive switch 72 becomes in an off state. Therefore, when the plate main body 21 is in the use position and the cover body 23 is in the open position, the magnet 71 sets the inductive switch 72 to the on state.

[0107] As Figure 19 shown, for example, consider a case where the cover body 23 is still in the open position and the plate main body 21 is in the retracted position. Then, the magnet 71 rotates integrally with the plate main body 21, changing its posture relative to the inductive switch 72.

[0108] Figure 20 The positional relationship between the magnet 71 and the inductive switch 72 when the plate main body 21 is in the retracted position is shown. As Figure 20 shown, in a state where the plate main body 21 is in the retracted position, the axis L1 of the magnet 71 does not cross the inductive switch 72. Also, the distance L11 between the first end 71a of the magnet 71 and the inductive switch 72 and the distance L12 between the second end 71b of the magnet 71 and the inductive switch 72 are equal to each other. As a result, one of the pair of guide pieces 72a is not magnetized, and one of the guide pieces 72a of the pair of guide pieces 72a no longer attracts the other guide piece 72a by magnetic force. Consequently, the contacts 72s of the respective guide pieces 72a come into a separated state, and the inductive switch 72 becomes in an off state. Therefore, the magnet 71 sets the inductive switch 72 to the off state at least when the plate main body 21 is in the retracted position.

[0109] According to the above configuration, when the plate body 21 is in the use position and the lid body 23 is in the open position, the magnet 71 sets the inductive switch 72 to the on state, enabling the lighting device 15 to light up. And by at least placing the plate body 21 in the retracted position, the magnet 71 sets the inductive switch 72 to the off state, enabling the lighting device 15 to go out. Therefore, even if, for example, the lid body 23 is not in the closed position, the lighting device 15 can be turned off by placing the plate body 21 in the retracted position. Thus, it is possible to avoid forgetting to turn off the lighting device 15 and achieve energy conservation. Moreover, by using only one magnet 71 and one inductive switch 72 each, the inductive switch 72 can be switched between the on state and the off state.

[0110] Imagine, for example, the case of using two magnets to switch the inductive switch between the on state and the off state. In this case, depending on the configuration of each magnet, when the plate body 21 rotates between the use position and the retracted position, there may be a situation where neither of the magnetic fields generated by the two magnets reaches the inductive switch. And when using two magnets, the magnetic fields generated by the two magnets may affect each other, and it is possible that the inductive switch does not operate properly. However, if the magnet switch 70 with the above configuration is adopted, by using only one magnet 71 and one inductive switch 72 each, the inductive switch 72 can be switched between the on state and the off state. Therefore, as described above, the problems caused when using two magnets can be avoided.

[0111] In addition, in the state where the plate body 21 is in the use position, by only switching the lid body 23 between the open position and the closed position, the inductive switch 72 can be switched between the on state and the off state. Therefore, for example, there is no need to provide a magnet 71 on the lid body 23, and thus the configuration of the lid body 23 can be simplified.

[0112] However, consider the following situation: for example, a shielding member is arranged between the magnet and the inductive switch to block the magnetic field generated by the magnet and set the inductive switch to the off state. And consider a configuration in which the shielding member is integrally provided with the lid body 23, for example, so that the shielding member and the lid body 23 slide integrally inside the plate body 21. In such a configuration, inside the plate body 21, it is difficult to arrange other components, etc. in the moving area of the shielding member that slides integrally with the lid body 23. On the other hand, as long as it is the magnet switch 70 with the above configuration, the moving direction of the moving body 74 is orthogonal to the direction in which the lid body 23 slides along the sliding mechanism 27. Therefore, it is difficult to impose restrictions on the arrangement of other components arranged inside the plate body 21, and an improvement in the degree of freedom of component layout can be achieved.

[0113] In addition, in the configuration where the shielding member slides integrally with the lid body 23, it may affect the configuration of the sliding mechanism 27. However, as long as the magnet switch 70 has the above configuration, the moving direction of the moving body 74 is orthogonal to the direction in which the lid body 23 slides along the sliding mechanism 27, so it is difficult to affect the configuration of the sliding mechanism 27. Therefore, the change in the configuration of the sliding mechanism 27 can be minimized.

[0114] In addition, in the configuration where the shielding member slides integrally with the lid body 23, the specifications of the lid body 23 including the shielding member are larger than those of the opening 21h, so it may limit the assembly order of the lid body 23 with respect to the board main body 21. In addition, when the shielding member is provided separately from the lid body 23, means for connecting the shielding member and the lid body 23 need to be provided. However, as long as the magnet switch 70 has the above configuration, the lid body 23 can be made of an existing configuration, so it does not limit the assembly order of the lid body 23 with respect to the board main body 21.

[0115] In addition, in the configuration where the shielding member slides integrally with the lid body 23, when the lid body 23 is in the open position, the shielding member does not block the magnetic field generated by the magnet 71, and the magnet and the inductive switch need to be on the same straight line. Therefore, in such a configuration, the timing of turning on and off the lighting device 15 is restricted. On the other hand, as long as the magnet switch 70 has the above configuration, regardless of the position of the lid body 23 with respect to the board main body 21, the magnet 71 can always be provided at a position corresponding to the inductive switch 72 on the board main body 21. Therefore, it is easy to appropriately adjust the configuration of the magnet switch 70, the configuration of the inductive switch 72, etc., and the timing of turning on and off the lighting device 15 can be appropriately adjusted.

[0116] · In the Figures 12 to 20 illustrated embodiment, the shape of the magnet 71 is not limited to a quadrangular prism shape, and for example, it can be a cylindrical shape or a polygonal prism shape.

[0117] · In the Figures 12 to 20 illustrated embodiment, the magnet switch 70 can be configured as follows: It is built into the board main body 21 in a state where the housing 73 is integrally formed with the board main body 21.

[0119] · In the Figures 12 to 20 illustrated embodiment, instead of the curved surface 74b, the moving body 74 can adopt a configuration having, for example, an inclined surface with a flat surface shape.

[0120] · In theFigures 12 to 20 In the illustrated embodiment, the biasing portion 75 is not limited to a compression spring. For example, it may be a metal spring or an elastic member made of resin. In short, the biasing portion 75 may be any member that biases the moving body 74 in a direction away from the housing 73. That is to say, the biasing portion 75 may be any member that biases the moving body 74 in a direction away from the inductive switch 72.

[0121] · In the embodiment, the plate body 21 may be configured without the third magnet 43. In this case, it is necessary to adjust the configurations of the first inductive switch 31 and the first magnet 41 so that the first inductive switch 31 is disposed within the magnetic field generated by the first magnet 41.

[0122] · In the embodiment, the vehicle sun visor module 10 may also be configured such that the decorative portion 11 does not have the second inductive switch 32 and the vehicle sun visor 20 does not have the second magnet 42.

[0123] · In the embodiment, the vehicle sun visor module 10 may also be configured such that the decorative portion 11 does not have the first inductive switch 31 and the vehicle sun visor 20 does not have the first magnet 41.

[0124] · In the embodiment, the cover body 23 may not be configured to be slidably movable relative to the plate body 21 by the sliding mechanism 27. For example, the cover body 23 may be rotatably disposed on the plate body 21 relative to the plate body 21. And the cover body 23 rotates relative to the plate body 21, so that the cover body 23 can move relative to the plate body 21 between an open position where the mirror 22 is exposed and a closed position where the mirror 22 is covered.

[0125] · In the embodiment, the vehicle sun visor module 10 may adopt a configuration without the decorative portion 11. In short, as long as at least a part of the ceiling constituting portion that constitutes the ceiling has the lighting device 15, the first inductive switch 31, and the second inductive switch 32. In this case, the ceiling constituting portion may be, for example, the ceiling roof that constitutes the entire ceiling. For example, when the ceiling constituting portion is the ceiling roof, the ceiling roof constitutes a part of the vehicle sun visor module 10.
