Disclosure of the invention

Problems to be solved by the invention

According to the vehicle sun visor 80 described above, as shown in FIG. 9 (B), the mirror lid 95 is configured to be stopped at the fully open position by directly contacting the fully open lever 99. At this time, since there is no mechanism between the fully open stopper 99 and the mirror cover 95 for reducing the sliding force in the opening direction of the mirror cover 95, when the mirror cover 95 hits the fully open stopper 99, A relatively loud noise is generated.

In order to suppress the abnormal noise, as shown in FIG. It is considered that the sliding force of the mirror cover 95 is absorbed to some extent by the silicon rubber 99k. However, the method of covering the fully open stopper 99 with silicon rubber 99k increases the material cost and the assembly man-hour, which is not preferable from the viewpoint of cost.

The present invention has been made to solve the above-described problems, and the technical problem of the present invention is to suppress abnormal noise caused by the mirror cover hitting the stagger so as not to increase the cost. It is to improve the quality of the sun visor.

Means for solving the problem

[0004] The problems described above are solved by the inventions of the claims.

The invention of claim 1 is a vehicle sun visor configured to cover or expose a mirror provided on the surface of the sun visor body by sliding the mirror lid along the surface of the sun visor body. The sun visor body is provided with a strobe that determines the slidable range of the mirror lid, and the mirror lid is made of a flexible material, and the end of the mirror lid in the sliding direction hits the stubber. It is characterized by being formed into a shape that can be elastically deformed with the force of.

According to the present invention, the mirror lid is made of a flexible material, and is formed into a shape that can be elastically deformed when the end of the mirror lid in the sliding direction hits the stagger. For this reason, the impact (sliding force of the mirror lid) when the mirror lid hits the stagger is absorbed to some extent by the elastic deformation of the end of the mirror lid. As a result, the contact of the mirror lid against the stagger is weakened and abnormal noise is suppressed.

In addition, since the end portion of the mirror lid is formed into a shape that can be elastically deformed, it is not necessary to use an elastic material or the like that is different from the material of the mirror lid. In other words, so as not to increase the cost, it is possible to improve the quality of the vehicle sun visor by suppressing abnormal noise caused by the mirror lid hitting the stagger.

[0006] According to the invention of claim 2, a slit-shaped notch extending along the edge of the mirror lid is formed at the end of the mirror lid in the sliding direction, and is located outside the notch. The edge of the mirror lid is configured to be elastically deformable by a force when it hits the stagger.

In this way, a slit-shaped notch extending along the edge of the mirror lid is formed at the end of the mirror lid. Due to the structure to be formed, the end of the mirror lid can be easily molded.

[0007] According to the invention of claim 3, a slit-like elongated hole extending along the edge of the mirror lid is formed at the end of the mirror lid in the sliding direction, and is located outside the elongated hole. It is characterized in that it is configured to be elastically deformable by the force when the edge of the mirror lid hits the stagger.

As described above, the slit-shaped long hole extending along the edge of the mirror lid is formed at the end of the mirror lid, so that the end of the mirror lid can be easily formed.

[0008] The invention of claim 4 is for a vehicle configured to cover or expose a mirror provided on the surface of the sun visor body by sliding the mirror lid along the surface of the sun visor body. The sun visor body is made of a flexible material, and the sun visor body is integrally formed with a stagger that determines a slidable range of the mirror lid, and the stopper touches the stopper. It is characterized by being formed into a shape that can be elastically deformed with the force of the moment.

For this reason, as in the first aspect of the invention, the same effect can be obtained as when the mirror lid side is formed into a shape that can be elastically deformed.

[0009] According to the invention of claim 5, the stopper includes a horizontal bar portion extending in a direction crossing the sliding direction of the mirror lid, and a vertical bar portion connecting the end of the horizontal bar portion to the sun visor body. Therefore, it is formed in a substantially L shape, and when the end face of the mirror lid hits against the horizontal bar part, the horizontal bar part elastically deforms in the direction of rotation with respect to the vertical bar part. It is characterized by being.

According to the invention of claim 6, the stopper is configured to be elastically deformable by a thin flat plate protruding from the inner wall surface of the sun visor body.

The invention's effect

[0010] According to the present invention, it is possible to improve the quality of the vehicle sun visor by suppressing abnormal noise caused by the mirror lid hitting the stagger, so as not to increase the cost.

BEST MODE FOR CARRYING OUT THE INVENTION [Embodiment 1]

Hereinafter, the vehicle sun visor according to Embodiment 1 of the present invention will be described with reference to FIGS. Here, FIG. 1 is an overall view of the vehicle sun visor according to the present embodiment, and FIG. 2 is a partial longitudinal sectional view of the vehicle sun visor. 3 is a plan view of the mirror lid, FIG. 4 is a plan view of the mirror lid fully opened, and FIG. 5 is a plan view of the mirror lid fully closed. Fig. 6 is a plan view showing a modified example of the mirror lid.

As shown in FIG. 1 (A), the vehicle sun visor 10 includes a substantially rectangular sun visor body 20 that blocks sunlight entering the vehicle interior. The sun visor body 20 is attached to the ceiling surface of the passenger compartment so as to be pivotable up and down by a support shaft (not shown). As a result, the sun visor body 20 can be turned up and down between a retracted position along the ceiling surface of the passenger compartment and a light shielding position along the window glass of the passenger compartment. Fig. 1 (A) shows the sun visor main body 20 lowered to the light shielding position.

[0014] As shown in FIGS. 2A and 2B, the sun visor body 20 is formed in a hollow plate shape by combining a shell-like front side shell 21 and a back side shell 22 together. The front-side shell 21 and the back-side shell 22 are molded, for example, by injecting polypropylene resin (PP) into a mold. Here, the front side of the sun visor body 20 refers to the surface on the side facing the occupant when the sun visor body 20 is in the light shielding position. Note that Fig. 2 (A) is an exploded sectional view taken along line ΠΑ-ΠΑ of Fig. 1 (A), and Fig. 2 (B) is a cross-sectional view taken along line の-の of Fig. 1 (A). The back-side shell 22 is partially omitted from illustration.

A front side shell 21 of the sun visor body 20 (hereinafter referred to as a sun visor body 20) is formed with a square recess 21h on the right side of the center, and a square mirror unit 30 is fitted in the square recess 21h.

In the rectangular recess 21h of the sun visor body 20, as shown in FIGS. 2 (A) and 2 (B), an opening 21e through which the mirror lid 40 (described later) of the mirror unit 30 is passed is formed in the left vertical wall portion. . The mirror lid 40 that has passed through the opening 21e is guided by a pair of slide rails 2ly formed inside the sun visor body 20 as shown in FIGS. 1 (A) and 2 (B). It is configured to be slidable inside.

Also, inside the sun visor body 20 is the tip of the mirror lid 40 that has been slid to the fully open position. A rib-like fully open stopper 25 is formed at a position where the edge 45 abuts.

As shown in FIG. 1 and FIG. 2 (A), the mirror unit 30 includes a square mirror 31, the mirror lid 40 covering the mirror 31, the mirror 31 fixed to the sun visor body 20, and a mirror. It comprises a frame-like support frame 33 that slidably supports the lid 40.

As shown in FIGS. 1B and 1C, the support frame 33 fixes the mirror 31 and the design frame portion 33f that covers the periphery of the rectangular recess 21h formed in the sun visor body 20 and holds the mirror lid 40. In addition, a vertical frame portion 33w for guiding the mirror lid 40 is formed. Here, FIG. 1 (B) is a cross-sectional view taken along the arrow B_B in FIG. 1 (A), and FIG. 1 (C) is an enlarged view of a portion C in FIG. 1 (B). On the inner side surface of the vertical frame portion 33w, as shown in FIGS. 1B and 1C, a mirror fixing collar portion 33k that partially supports the periphery of the mirror 31 is formed. On the inner side surface of the vertical frame portion 33w, a guide surface 33x is formed on the upper side (design frame portion 33f side) of the mirror fixing collar portion 33k to guide the mirror cover 40 from both sides in the width direction. . Further, a pressing surface 33p is formed on the back side of the design frame portion 33f so as to protrude perpendicularly to the guide surface 33x and press the mirror lid 40 from above. That is, the mirror lid 40 is restrained from both sides in the width direction by both guide surfaces 33x of the support frame 33, and is restrained from the thickness direction (up and down direction) by the pressing surface 33p of the support frame 33 and the upper surface of the mirror 31. To hold it slidable (see Fig. 1 (B)).

[0016] As shown in FIG. 2 (A), the support frame 33 has a mirror lid passage 33z formed by cutting a vertical frame portion 33w at a position corresponding to the opening 21e of the rectangular recess 21h of the sun visor body 20. Is formed. Accordingly, the mirror lid 40 slidably supported by the support frame 33 can enter the sun visor body 20 through the mirror lid passage 33z and the opening 21e of the rectangular recess 21h.

In addition, in the vertical frame portion 33w of the support frame 33, as shown in FIG. 4 (A), the mirror cover 40 is fully closed (position where the mirror 31 is completely covered) at a position opposite to the mirror cover passage 33z. A fully-closed stopper 33s is formed to stop it.

Furthermore, on the lower surface of the vertical frame portion 33w (the side opposite to the design frame portion 33f), a substantially arrow-shaped engagement inserted into and connected to a plurality of mounting holes (not shown) formed in the rectangular recess 21h of the sun visor body 20 is provided. A claw 33y is formed (see Fig. 2 (A)). The engaging claw 33y was elastically deformed in the direction of narrowing in the process of passing through the mounting hole of the rectangular recess 21h, and passed through the mounting hole. After that, it is configured to expand with elasticity and to be connected to the sun visor body 20.

The support frame 33 is made of, for example, polypropylene resin (PP).

As shown in FIG. 1 (B) and FIG. 3, the mirror lid 40 is composed of a pair of rail portions 43 extending in the sliding direction and a flat lid body portion 41 passed between the rail portions 43. The cross-sectional shape is shaped like a flat gate. As shown in FIG. 1B, the rail portion 43 of the mirror lid 40 is sandwiched between the pressing surface 33p of the support frame 33 and the upper surface of the mirror 31, and the rail portion 43 is supported by the support frame 33. It is configured to be guided by both guide surfaces 33x.

As shown in FIG. 3 (A), the front end 4Π of the lid main body 41 of the mirror lid 40 is formed in a convex curved surface shape, and an inverted L-shaped notch 44 is formed on the front end 41f. ing. That is, the notch 44 includes a vertical portion 44t extending in the sliding direction (longitudinal direction) of the mirror lid 40 and a slit portion 44w extending in the width direction along the tip edge 45 of the mirror lid 40. Here, FIG. 3 (B) is a cross-sectional view taken along the line BB in FIG. 3 (A), and FIG. 3 (C) is a view taken along the line C-C in FIG. 3 (A).

[0018] The mirror lid 40 is made of, for example, ABS resin (acrylonitrile 'butadiene' styrene resin), and the lid body 41 has flexibility. For this reason, the thin and narrow tip edge 45 positioned outside the notch 44 in the mirror lid 40 can be elastically deformed. Therefore, when the mirror lid 40 slides to the fully open position (the position where the mirror 31 is exposed most) and the tip edge 45 hits the fully open stopper 25 of the sun visor body 20, the tip edge 45 of the mirror lid 40 is elastically deformed. The shock is absorbed.

The base end portion 41b (rear end portion 41b) of the lid main body portion 41 of the mirror lid 40 is formed in a concave curved surface shape so that both ends in the width direction slightly protrude rearward as shown in FIG. Yes. Then, the end surface 41q of the rear end portion 41b of the mirror lid 40 comes to substantially abut against the fully closed stopper 33s of the support frame 33 in the fully closed position.

Further, on the upper surface of the lid main body portion 41 of the mirror lid 40, a handle portion 47 having a substantially semi-cylindrical cross section extending in the width direction of the mirror lid 40 is formed at the position of the base end portion 41b. Using this handle, the occupant can slide the mirror lid 40 between the fully closed position and the fully open position. Next, functions of the vehicle sun visor 10 will be briefly described.

In the state where the mirror cover 40 is in the fully closed position, the tip 41f of the mirror cover 40 moves from the mirror cover passage 33z of the support frame 33, the opening 21e of the rectangular recess 21h of the sun visor body 20 to the inside of the sun visor body 20. (See Figure 5). Further, the front end portion 41f of the mirror lid 40 is supported by a pair of slide rails 21y inside the sun visor body 20 on both sides in the width direction.

When the mirror 31 is used, the handle 47 is used to slide the mirror cover 40 in the opening direction (left direction in FIG. 5). At this time, the mirror lid 40 slides in the opening direction while being guided by the support frame 33 and the mirror 31 and further guided by the slide rail 21y of the sun visor body 20. As a result, the mirror 31 covered with the mirror lid 40 appears, and the passenger can use the mirror 31. When the mirror cover 40 reaches the fully open position, the tip edge 45 of the mirror cover 40 hits the fully open stopper 25 of the sun visor body 20 and the mirror cover 40 is held in that position. Since the tip edge 45 of the mirror lid 40 is configured to be elastically deformable, the impact (slider of the mirror lid 40) when the mirror lid 40 hits the fully open stopper 25 is absorbed to some extent by the elastic deformation of the tip edge 45. Is done. For this reason, the contact of the mirror lid 40 with respect to the fully opened stopper 25 is weakened, and abnormal noise is suppressed.

[0020] Here, in the vehicle sun visor 10 according to the present embodiment, because the tip edge 45 of the mirror lid 40 is formed into a shape capable of inertial deformation, the method for suppressing abnormal noise when fully opened is There is almost no cost increase because it is not necessary to use an elastic material that is different from the material of Mira One Lid 40.

That is, in order not to increase the cost, the noise when the mirror cover 40 hits the fully open stopper 25 can be suppressed, and the quality of the vehicle sun visor 10 can be improved.

Here, in the present embodiment, an example in which the tip edge 45 is configured to be elastically deformable by forming an inverted L-shaped notch 44 at the tip 41f of the mirror lid 40 is shown in FIG. 6 (A) ( As shown in B), by forming a long hole 54 in the tip portion 41f of the mirror lid 40, the tip edge 45 can be configured to be elastically deformable.

[Embodiment 2]

Hereinafter, the vehicle sun visor according to Embodiment 2 of the present invention will be described with reference to FIGS. I do. The vehicle sun visor according to the first embodiment described above is a system that absorbs the impact when fully opened by configuring the tip edge 45 of the mirror lid 40 to be elastically deformable. However, in the vehicle sun visor according to the present embodiment, The fully open stopper 65 side is configured to be elastically deformable, so that it absorbs shocks when fully open.

7A is a plan view of the fully open stopper 65, FIG. 7B is a side view, and FIG. 7C is a perspective view.

The fully open stagger 65 is formed in a substantially L shape by a horizontal bar portion 65y extending in a direction crossing the sliding direction of the mirror lid 40 and a vertical bar portion 65t connecting the horizontal bar portion 65y to the sun visor body 20. Yes. The vertical bar portion 65t protrudes from the inner wall surface of the sun visor body 20 in the thickness direction, and the end of the horizontal bar portion 65y is connected to the protruding end. The fully open stopper 65 is provided at the position of the molding opening 21a of the sun visor body 20, and is integrally formed with the front shell 21 when the front shell 21 of the sun visor main body 20 is molded with a mold.

When the tip of the mirror lid 40 hits the horizontal bar 65y, the fully open stopper 65 is elastically deformed so that the horizontal bar 65y rotates with respect to the vertical bar 65t, and the impact when the mirror lid 40 hits Absorbs. For this reason, the contact of the mirror cover 40 with the fully open stopper 65 is weakened, and abnormal noise is suppressed.

Further, the fully open stopper 65 is integrally formed with the sun visor body 20, so that the cost is hardly increased.

Figures 8 (A) to 8 (C) show examples of changes to the fully open stopper 65.

The fully open stopper 65 shown in FIG. 8 (A) includes a horizontal bar portion 65y extending in a direction crossing the sliding direction of the mirror cover 40, and a vertical bar portion 65y connecting the horizontal bar portion 65y to the sun visor body 20 The vertical bar portion 65t is configured to extend in the sliding direction of the mirror lid 40. As a result, when the tip of the mirror lid 40 hits the horizontal bar portion 65y, the horizontal bar portion 65y rotates with respect to the vertical bar portion 65t as in the case of the fully open stagger 65 shown in FIG. It will be able to absorb the shock when it hits the mirror lid 40.

A fully open stopper 65 shown in FIG. 8 (B) is obtained by bending the horizontal bar portion 65y of the fully open stopper 65 shown in FIG. 8 (A) into a substantially arcuate plane. As a result, the fully open stopper 65 is Furthermore, it becomes easy to elastically deform.

The fully open stopper 75 shown in FIG. 8C is configured to be elastically deformable by bending a thin flat plate protruding in the thickness direction from the inner wall surface of the sun visor body 20 into a substantially U shape. This makes it possible to absorb an impact when the mirror cover 40 hits, as in the case of the fully open stagger 65 shown in FIG.

In the first embodiment and the second embodiment, the configuration for suppressing the abnormal noise when the mirror lid 40 hits the fully open stoppers 25 and 65 has been described. However, the mirror lid 40 is fully closed by using the above configuration. It is also possible to suppress abnormal noise when hitting 33s.

In Embodiment 1, an example in which the tip edge 45 is configured to be elastically deformable by forming an inverted L-shaped notch 44 and a long hole 54 at the tip 41f of the mirror lid 40 has been shown. 45 may be formed thin and bend upward or downward to be elastically deformable. Further, in the second embodiment, a force showing an example in which the fully open stopper 65 is formed in a substantially L shape from the horizontal bar portion 65y and the vertical bar portion 65t is a direction in which the fully open stopper 65 intersects the sliding direction of the mirror lid 40. It is also possible to constitute from a thin, elastically deformable flat plate extending in the direction.
