Description

[Technical field]

[0001] The technology disclosed in this specification relates to a retaining structure for a sun visor for a vehicle. [Background technology]

[0002] Conventionally, for example, a sun visor provided in a vehicle is known as described in Patent Document 1. The vehicle sun visor described in Patent Document 1 has a configuration that has been widely used in the past. Specifically, a substantially rectangular, plate-like light shielding plate is held by a generally L-shaped support shaft, and the light shielding plate is rotated about an axis extending horizontally to raise and lower, and is also rotated about an axis extending vertically to change the position from the front to the side of the occupant. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-101851 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned general vehicle sun visor has a rod-shaped engaging portion on the sunshade for hooking onto a hook provided on the ceiling of the vehicle. When the sunshade is in a use state along the windshield and along the ceiling, the engaging portion can be hooked onto the hook to stably hold the sunshade on the ceiling. This engaging portion is configured such that a concave cutout is provided near the end of the sunshade opposite the vertically extending support shaft (rotating shaft), and the cutout is spanned by a rod-shaped member.

[0005] However, when moving the sunshade from the front (along the front window) to the side (along the side window), the task of removing the locked part from the hook, which is engaged with the hook, and the task of hooking the locked part onto the hook when moving the sunshade from the side to the front are both time-consuming and cumbersome. In particular, when driving, the driver may lose focus on the road ahead if he or she shifts his or her gaze from the front to the hook, which is dangerous. In addition, if the sunshade is not fixed correctly by fumbling around, there is a risk of abnormal noises being generated while driving.

[0006] Furthermore, since the engaging portion is configured so that a rod-shaped member spans a concave cutout portion in the light shielding plate, the outer shape of the light shielding plate cannot be made simple, and a hook needs to be provided on the ceiling side, creating a demand for improved design within the vehicle interior.

[0007] The technology disclosed in this specification was developed based on the above circumstances, and its object is to provide a holding structure for a vehicle sun visor that is excellent in operability of the shading plate and in design. [Means for solving the problem]

[0008] The technology disclosed in this specification, which has been completed to solve the above problems, includes a support arm having a first arm portion and a second arm portion connected to the first arm portion at a right angle, and a plate-shaped light blocking plate supported by the support arm so as to be rotatable about an axis of the first arm portion and about an axis of the second arm portion, and capable of changing its position among a first state in which the light blocking plate is aligned with the ceiling of the vehicle, a second state in which the light blocking plate is aligned with the front window, and a third state in which the light blocking plate is aligned with a side window, and the light blocking plate is disposed at an upper end in the second state. The holding structure for a vehicle sun visor has a held portion including a first magnetic material for holding the sun visor to the ceiling on at least a portion of a first end portion of the sun visor, and a holding portion including a second magnetic material and having a receiving surface facing downward is provided in an area of ​​the ceiling including a portion that faces the held portion of the sun visor in the first state and the second state, and in the first state and the second state, the held portion of the sun visor can be held in a state where it is attracted by magnetic force from inside the vehicle cabin against the receiving surface of the holding portion.

[0009] According to the above structure, the light shielding plate can be held on the ceiling of the vehicle by using magnetic force. In other words, by simply bringing the held portion of the light shielding plate close to the holding portion provided on the ceiling from inside the vehicle cabin, the held portion can be attracted by magnetic force to the receiving surface of the holding portion facing downward and can be stably held. Furthermore, when moving the light shielding plate, the held portion can be released by simply pulling it lightly in a direction away from the holding portion. Therefore, since it is no longer necessary to perform the work of engaging and removing the engaged portion that spans the recess of the light shielding plate with the hook provided on the ceiling as in the conventional method, the operability of the light shielding plate is improved. In addition, since it can be operated intuitively without looking at the screen, safety during driving is also improved.

[0010] In addition, there is no need to provide an engaging portion to bridge the recess on the light-blocking plate or a hook on the ceiling as in the conventional method; it is sufficient to provide a magnetic body for each, so the light-blocking plate can be made into a simpler shape that is closer to a rectangle than in the conventional method, and a hook is no longer required on the ceiling side, improving the design of the interior of the vehicle.

[0011] The first arm portion may be arranged along the first end portion, the first magnetic body may be positioned at a position offset from the axis of the first arm portion, and the holding portion may be movable in the vertical direction following the held portion which moves as the light shielding plate changes position between the first state and the second state.

[0012] According to the above structure, even if a change in the posture of the light blocking plate causes the held portion to move vertically relative to the ceiling, the holding portion can move up and down, allowing the receiving surface to maintain a state in which the held portion and the holding portion are attracted to each other by magnetic force, so that the held portion of the light blocking plate can be held by the holding portion regardless of the change in posture of the light blocking plate between the first state and the second state.

[0013] The first arm portion may be embedded in the first end portion along the first end portion, and the first magnetic body may be disposed at a position closer to an end face of the first end portion than to an axis of the first arm portion. With this structure, the magnetic force of the first magnetic body can be utilized more effectively.

[0014] The end face of the first end may be rounded. With this structure, when the light blocking plate changes its position between the first state and the second state, the end face of the first end can be smoothly slid along the receiving surface of the holding part.

[0015] The receiving surface of the holding portion may be inclined upward from the front to the rear of the vehicle. With this structure, when the attitude of the light blocking plate is changed from the third state to the second state to hold the held portion on the holding portion, the held portion can be easily guided to the receiving surface. Effect of the Invention

[0016] According to the technology disclosed in this specification, it is possible to provide a holding structure for a sun visor for a vehicle that is excellent in operability of a light shielding plate and in design. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] An embodiment will be described with reference to Fig. 1 to Fig. 6. In this embodiment, a retaining structure 1 for a vehicle sun visor (one example of a vehicle sun visor) 10 will be illustrated. Note that the directions of the arrows FR and RR shown in each drawing indicate the forward direction (the direction in which the vehicle travels) and the rearward direction, respectively, the directions of the arrows IN and OUT indicate the inner and outer directions in the vehicle width direction, respectively, and the directions of the arrows UP and DW indicate the upward and downward directions, respectively.

[0019] The vehicle sun visor 10 is attached to a ceiling 11 in front when viewed from the driver's seat and the passenger seat, and has a function of blocking strong light such as direct sunlight entering from outside the vehicle compartment by using a light shielding plate 30 provided on the vehicle sun visor 10.

[0020] The vehicle sun visor 10 of this embodiment includes an L-shaped arm (an example of a support arm) 20 extending from a bearing portion 23 provided on the ceiling 11 of the vehicle, a light shielding plate 30 connected to the L-shaped arm 20, and a visor holder (an example of a holding portion) 40, as shown in FIG. 1, for example.

[0021] The light shielding plate 30 can change between a first state (see FIG. 2) in which the plate surface is aligned with the ceiling surface 11A, a second state (see FIG. 3) in which the plate surface is aligned with the plate surface of the vehicle's front window, and a third state (see FIG. 4) in which the plate surface is aligned with the plate surface of the vehicle's side window. In the following explanation, the configuration on the right side in the vehicle width direction (driver's seat side) will be explained, but a similar configuration is also provided on the left side in the vehicle width direction (passenger's seat side).

[0022] The L-shaped arm 20 is composed of a first arm portion 21 extending horizontally and a second arm portion 22 connected to one end of the first arm portion 21 at a right angle to the first arm portion 21, and has an overall L-shape. The L-shaped arm 20 has a round bar shape with a circular cross section. The second arm portion 22 extends vertically from a bearing portion 23 provided on the ceiling 11, and is supported by the bearing portion 23 through a bearing hole provided in the bearing portion 23 in a state in which it can rotate around its axis (second axis L2). With this configuration, even if the second arm portion 22 rotates around the second axis L2, the first arm portion 21 connected to the second arm portion 22 at a right angle can always maintain a horizontal state. In addition, the second arm portion 22 is shorter in length than the first arm portion 21, and when one end side of the second arm portion 22 is supported by the bearing portion 23, the first arm portion 21 is positioned near the ceiling surface 11A.

[0023] A light shielding plate 30 is attached to the first arm portion 21. The light shielding plate 30 is made of a resin material having light shielding properties, and has a horizontally long, approximately rectangular plate shape as shown in Fig. 1. In the following description, taking the second state (the state in Figs. 1 and 3) in which the light shielding plate 30 is aligned with the front window as a reference, an upper corner portion of the light shielding plate 30 that is located on the second arm portion 22 side (outside in the vehicle width direction) is a notch portion 31 that is cut out in an approximately L shape.

[0024] The light shielding plate 30 is formed with a hole 32 extending from the cutout surface of the cutout portion 31 along the longitudinal direction (vehicle width direction) of the light shielding plate 30, and the first arm portion 21 is inserted into the hole 32 from the outside of the vehicle compartment, thereby attaching the light shielding plate 30 to the L-shaped arm 20. That is, the first arm portion 21 is disposed along the upper end surface of the light shielding plate 30. The hole portion 32 functions as a bearing portion 23 for the first arm portion 21, and the light shielding plate 30 is rotatable in the vertical direction with the first arm portion 21 as a rotation axis (first axis L1). The first arm portion 21 extends slightly inward in the vehicle width direction (left side in FIG. 1) from the center of the light shielding plate 30 in the longitudinal direction.

[0025] In addition, an iron core (an example of a first magnetic body) 35 is embedded in the light shielding plate 30 of this embodiment. The iron core 35 is embedded in a position adjacent to an inner end (left end in FIG. 1) located opposite an outer end (right end in FIG. 1) where the second arm portion 22 is located, in the upper end (hereinafter referred to as a first end 33) of the light shielding plate 30 in the second state (see FIG. 1). In other words, the iron core 35 is provided in a part of the first end 33 of the light shielding plate 30 without being exposed to the outside (surface of the light shielding plate 30).

[0026] The iron core 35 is in the shape of a round bar shorter than the first arm portion 21, and its axis (referred to as the third axis L3) is arranged parallel to the first axis L1 of the first arm portion 21 and above the first axis L1 (see Figs. 1 and 5). It can also be said that the third axis L3 is arranged closer to the ceiling 11 than the first axis L1 in the second state. It can also be said that the third axis L3 is arranged closer to the edge portion of the first end portion 33 (the highest position in the second state) than the first axis L1. It can also be said that the first axis L1 and the third axis L3 are misaligned in the up-down direction in the second state.

[0027] 5, the first end 33 of the light blocking plate 30 has a semicircular (rounded) cross section with end faces 33A continuing continuously from the front and back plate surfaces of the light blocking plate 30, and the iron core 35 is embedded in a part of the first end 33 of the light blocking plate 30 so that the upper part of its outer periphery fits along the rounded end face 33A of the first end 33 of the light blocking plate 30. Hereinafter, the part of the first end 33 of the light blocking plate 30 where the iron core 35 is embedded will be referred to as the held part 34.

[0028] Meanwhile, a visor holder (an example of a holding portion) 40 is provided on the ceiling 11 of the vehicle. As shown in Fig. 1, the visor holder 40 is provided at a position facing the held portion 34 of the light shielding plate 30 in the second state in the vehicle width direction. Also, as shown in Figs. 5 and 6, the visor holder 40 is provided in an area including a position facing the held portion 34 of the light shielding plate 30 in the first state and the second state in the front-rear direction.

[0029] The visor holder 40 is configured to include a magnet (an example of a second magnetic body) 45 and a slide holder 41 that holds the magnet 45 movably in the vertical direction. As shown in Fig. 5 and Fig. 6, the slide holder 41 is in the shape of a box composed of a rectangular flat bottom wall 42 and standing walls 43 rising from four sides of the bottom wall 42, and two of the four standing walls 43 that face each other in the front-rear direction have slide locking holes 44 extending in the vertical direction formed through the respective plate surfaces.

[0030] On the other hand, the ceiling 11 is formed with a holder insertion hole 12 having a size that allows the box-shaped slide holder 41 to be inserted therethrough, penetrating the plate surface. This holder insertion hole 12 is formed such that a pair of hole edges arranged opposite each other extend in the vehicle width direction, and another pair of hole edges extend in the vehicle front-rear direction. Note that the portion of the vehicle ceiling 11 where this holder insertion hole 12 is provided is inclined so as to gently incline upward from the front to the rear, and of the pair of hole edges (pair of hole edges opposed to each other in the front-rear direction) extending in the vehicle width direction, the hole edge arranged at the rear is arranged at a higher position than the hole edge arranged at the front.

[0031] Of the opposing hole edges of the holder insertion hole 12, the center of each hole edge extending in the vehicle width direction (hole edges opposing in the front-rear direction) is provided with a holder holding portion 13. These holder holding portions 13 are generally J-shaped and include an outer wall portion 14 rising upward from each hole edge, an upper wall portion 15 bending in an L-shape from the upper end of the outer wall portion 14 in a direction approaching each other, and an inner wall portion 16 of the upper wall portion 15 falling from the other end side of the outer wall portion 14, and the lower ends of the two inner wall portions 16 are formed with claw portions 17 protruding in directions away from each other (opposite sides). These claw portions 17 are arranged in the slide locking hole 44 of the slide holder 41 in a state in which they can slide up and down.

[0032] With this configuration, the slide holder 41 is held in a state in which it can move up and down relative to the ceiling 11 between an upper limit position (the state in FIG. 5) where the claw portion 17 is disposed at the lower end of the slide locking hole 44, and a lower limit position (the state in FIG. 6) where the claw portion 17 is disposed at the upper end of the slide locking hole 44. It can also be said that the movement of the slide holder 41 in the up and down direction is restricted by the claw portion 17.

[0033] In addition, the size and position of the slide engagement hole 44 in the vertical wall 43 are set so that, in the upper limit position (see Figure 5), the lower surface (an example of a receiving surface) 42B of the bottom wall 42 protrudes slightly downward (toward the inside of the vehicle compartment) from the ceiling surface 11A, and in the lower limit position (see Figure 6), the lower end of the slide engagement hole 44 is not exposed below the ceiling surface 11A.

[0034] The slide holder 41 is configured to move up and down with the lower surface 42B of the bottom wall 42 parallel to the ceiling surface 11A. In other words, the slide holder 41 is configured so that the lower surface 42B of the bottom wall 42 is inclined upward from the front to the rear in either state in which the slide holder 41 is disposed between the upper limit position and the lower limit position.

[0035] Furthermore, a plate-shaped magnet (an example of a second magnetic body) 45 is disposed on the upper surface 42A of the bottom wall 42 of the slide holder 41. The dimension of the magnet 45 in the vehicle width direction is set to be close to the length dimension of the iron core 35, as shown in FIG. 1. The dimension of the magnet 45 in the front-rear direction is set to be able to face both the iron core 35 in the second state and the iron core 35 in the first state, as shown in FIGS. 5 and 6. The magnet 45 has a magnetic force that can attract the iron core 35 embedded in the first end 33 of the light shielding plate 30.

[0036] The holding structure 1 for the sun visor 10 for a vehicle according to this embodiment is as described above, and its operation and effect will be described below. The holding structure 1 for the sun visor 10 for a vehicle according to this embodiment includes an L-shaped arm 20 having a first arm portion 21 and a second arm portion 22 connected to the first arm portion 21 at a right angle, and a plate-shaped light shielding plate 30 that is supported by the L-shaped arm 20 so as to be rotatable around an axis L1 of the first arm portion 21 and an axis L2 of the second arm portion 22 and can change its position among a first state in which the light shielding plate 30 is positioned along the roof 11 of the vehicle, a second state in which the light shielding plate 30 is positioned along the front window, and a third state in which the light shielding plate 30 is positioned along the side window. At least a portion of one end 33 has a held portion 34 which includes an iron core 35 and is used to hold the sunshade 30 to the ceiling 11, and a slide holder 41 (visor holder 40) having a bottom wall 42 with an underside 42B which includes a magnet 45 and faces downward is provided in an area of ​​the ceiling 11 including a portion which faces the held portion 34 of the sunshade 30 in the first and second states, and in the first and second states, the held portion 34 of the sunshade 30 can be held in a state where it is attracted by magnetic force from inside the vehicle cabin against the underside 42B of the bottom wall 42 of the slide holder 41.

[0037] According to the above structure, the light shielding plate 30 can be held on the ceiling 11 of the vehicle by utilizing magnetic force. That is, by simply bringing the held portion 34 of the light shielding plate 30 close to the visor holder 40 provided on the ceiling 11 from inside the vehicle compartment, the held portion 34 is attracted by magnetic force to the lower surface 42B of the bottom wall 42 of the slide holder 41 facing downward, and can be stably held. When moving the light shielding plate 30, the held portion 34 can be released by simply pulling it lightly in a direction away from the visor holder 40. Therefore, since the conventional work of engaging the engaged portion that spans the recess of the light shielding plate with a hook provided on the ceiling and removing it is not necessary, the operability of the light shielding plate 30 is improved. In addition, since it can be operated intuitively without directing one's eyes, safety during driving is also improved.

[0038] Furthermore, there is no need to provide an engaging portion to bridge the recess on the light shielding plate or to provide a hook on the ceiling as in the conventional method, and it is only necessary to provide a magnetic body (iron core 35 and magnet 45) for each, so that the light shielding plate 30 can be made into a simpler shape that is closer to a rectangle than in the conventional method, and a hook is no longer required on the ceiling 11 side, improving the design of the interior of the vehicle.

[0039] In addition, the first arm portion 21 is arranged along the edge of the first end portion 33, the iron core 35 is positioned at a position offset from the axis L1 of the first arm portion 21, and the visor holder 40 (slide holder 41) is movable in the vertical direction following the held portion 34 which moves as the light shielding plate 30 changes its position between the first state and the second state.

[0040] According to the above structure, even if the held portion 34 moves vertically relative to the ceiling 11 due to a change in the posture of the shade 30, the slide holder 41 of the visor holder 40 moves vertically, so that the underside 42B of the bottom wall 42 can maintain a state in which the held portion 34 is attracted to it by magnetic force, thereby allowing the held portion 34 of the shade 30 to be held by the visor holder 40 regardless of the change in posture of the shade 30 between the first and second states.

[0041] Moreover, first arm portion 21 is embedded in first end portion 33 along the edge of first end portion 33, and iron core 35 is disposed at a position closer to the edge of first end portion 33 than axis L1 of first arm portion 21. With this structure, the magnetic force of iron core 35 can be utilized more effectively.

[0042] In addition, the end surface 33A of the first end portion 33 is rounded. With this structure, when the light shielding plate 30 changes its position between the first state and the second state, the end surface 33A of the first end portion 33 can be smoothly slid along the lower surface 42B of the bottom wall 42 of the slide holder 41.

[0043] In addition, the lower surface 42B of the bottom wall 42 of the slide holder 41 is inclined upward from the front to the rear of the vehicle. With this structure, when the attitude of the light shielding plate 30 is changed from the third state to the second state to hold the held portion 34 on the visor holder 40, the held portion 34 can be easily guided to the lower surface 42B of the bottom wall 42.

[0044] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and for example, the following embodiments are also included within the technical scope.

[0045] (1) In the above embodiment, the iron core 35 is used as the first magnetic body, and the magnet 45 is used as the second magnetic body, but the combination of the first magnetic body and the second magnetic body is not limited to the above embodiment as long as they are materials capable of generating a magnetic force between each other. For example, chromium oxide, cobalt, ferrite, non-oxidized metal magnetic body (oxide), etc. can be used instead of the iron core, or magnets can be combined.

[0046] (2) In the above embodiment, the axis L3 of the iron core 35 is disposed at a position offset from the axis L1 of the first arm portion 21, but the axis of the first magnetic body and the axis of the first arm portion may be disposed coaxially. In such a case, the axis of the iron core does not move when the light shielding plate is rotated around the first arm portion as a rotation axis.

[0047] (3) In the above embodiment, the visor holder 40 is shown to be movable in the vertical direction. However, in a case where the first end of the light shielding plate does not move in the vertical direction due to the rotation of the light shielding plate, the holding portion may not move in the vertical direction.

[0048] (4) The technical scope also includes configurations in which the first end of the light shielding plate is not rounded.

[0049] (5) A configuration in which the receiving surface of the holding part is not inclined is also included in the technical scope.

[0050] (6) In the above embodiment, the support arm is L-shaped. However, the technology disclosed in this specification is also applicable to the support arm being crank-shaped. [Explanation of symbols]
