Abstract

PURPOSE:To attempt to simplify the operation of the sunvisor in the title by providing a bent part for hanging the sunvisor in the front inside a car room and by storing the sunvisor inside a hollow space by way of driving a motor when a detection means detects that the sunvisor is changed from its bending state to its extending state. CONSTITUTION:Each belt wire 25 is moved to the front side by way of the engagement of the tooth part 23a of a sprocket 23 with a plural number of holes 27 formed in one row on a pair of belt wires 25 and a slider 13 is slided along a rail 11 by driving a motor 21 at the time when a sunvisor is used. Consequently, when a sunvisor main body 17 is pushed and moved and a micro- switch 31 is switched on, the motor 21 is stopped. In this state, the sunvisor main body 17 is manually hung downward with its hinge part 18 as its center to shade a light. Thereafter, when the sunvisor main body 17 is stored, the sunvisor main body 17 is moved upward and with the micro-switch pressed on again, the motor 21 is reversely rotated to store the sunvisor main body 17.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a hollow space formed between a roof panel and an interior component mounted on the inside of a vehicle interior of a roof. The present invention relates to an electric sliding type sun visor that stores a sun visor that can freely extend and retract toward the front wind panel from an opening formed in the front wind panel.

Conventional technology Generally, a sun visor is installed on the roof side of a car above the driver's or passenger's seat to block direct sunlight from the front wind panel.
A normal sun visor is equipped with a hinge mechanism that allows the angle of attachment to the roof to be varied.When not in use, the sun visor is folded toward the roof using the hinge mechanism, and only when in use it hangs down from the front of the front wind panel on the passenger compartment side. It is normal for it to be cold.

On the other hand, for example, Japanese Patent Publication No. 45-31016 and Japanese Patent Publication No. 45-31017 disclose an electric sliding sun visor in a hollow space formed between a roof panel and an interior member attached to the interior side of the roof. A structure is disclosed in which the sun visor is stored and when the sun visor is used, the rotational force of the motor causes the sun visor to slide toward the front wind panel from an opening formed in the front of the interior member.

According to this configuration of the sun visor, since the sun visor is hidden behind the roof side by the interior member when not in use, there is an advantage that the interior of the vehicle becomes larger and the exterior appearance is improved.

Problems to be Solved by the Invention However, in the configuration of such a conventional electric sliding sun visor, the sun visor, which is housed in a hollow space formed between an interior member and a roof panel, is placed in front of the interior member. Since the structure was such that it could simply be slid from the opening formed toward the front wind panel,
There is a problem in that constraints are placed on the shape, dimensions, etc. of the sun visor, making it difficult to ensure a sufficient degree of light shielding.

For example, enlarging the shape of the sun visor to increase the degree of light blocking poses a problem in terms of the storage space on the roof side.Especially in the case of a vehicle with a sunroof, it is difficult to store the sun visor on the roof side. Since it is extremely difficult to provide sufficient space, the dimensions of the sun visor must necessarily be reduced.

On the other hand, in order to increase the degree of light shielding while keeping the shape of the sun visor small, a bent part is formed near the rear end of the sun visor to allow the sun visor to hang down to the front surface of the front window panel on the passenger compartment side. The sun visor may be slid from an opening formed in the front of the interior member toward the front wind panel, and then allowed to hang down from the bent portion. However, in such a configuration,
When storing the sun visor, it is not possible to drive the motor with the sun visor hanging down at the bend, so first manually return the sun visor to the slidable position, and then turn the motor switch on. This requires a two-step operation of turning it on, which is cumbersome and poses a safety problem when the vehicle is running.

SUMMARY OF THE INVENTION Therefore, the present invention provides an electric sliding sun visor that can solve the problems of conventional electric sliding sun visors, ensure sufficient light shielding, and improve operability when sliding. The purpose is to

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention uses the rotational force of a motor to fill the hollow space formed between the interior member attached to the interior side of the roof and the roof panel. In an electric sliding type sun visor configuration in which a sun visor is stored that can freely protrude and retract from an opening formed in the front of an interior member toward the front wind panel, the sun visor is caused to hang from the front surface of the front wind panel on the vehicle interior side. A detecting means for detecting that the sun visor changes from a bent state to an extended state is provided at a predetermined portion of the sun visor, and based on a signal obtained from the detecting means, the This is the configuration of an electric sliding sun visor that controls the retracting operation of the sun visor.

Function According to this configuration, when the sun visor is not in use, the sun visor is stored in the hollow space formed between the roof panel and the interior member attached to the interior side of the roof. As the area becomes wider, the appearance is improved.

Further, when the sun visor is used, when the sun visor is slid toward the front wind panel by the rotational force of the motor, the sun visor moves toward the front of the vehicle body. Here, the degree of light shielding for the occupant can be sufficiently increased by causing the sun visor to hang down from the bent portion to the front surface of the front window panel on the vehicle interior side by manual operation or the like by the occupant.

Furthermore, when the sun visor is to be stored in its original state, when the sun visor is moved up manually by the occupant, the means for detecting that the sun visor has changed from the folded state to the extended state emits a signal. Based on the signal obtained from the detection means, a drive signal is issued to the motor to rotate the motor in the opposite direction to that during sliding, and the sun visor is retracted into the hollow portion.

In the above-described operation, when the sun visor is retracted, an operating mode is obtained in which the occupant only has to perform an operation to move the sun visor, which is suspended in the used state, upward toward the roof side.

A limit switch 33 that comes into contact with 30 is attached.

On the other hand, at a substantially center position in the vehicle width direction and at the front end of the sun visor body 17, contact between the sun visor body 17 and the front wind panel 7 is sensed, and the sun visor body 17 becomes parallel to the slider 13. A microswitch 31 is provided as a detection means for detecting. That is, the detection signal obtained from this microswitch 31 is guided to a control section (not shown), and the retracting operation of the sun visor body 17 by the motor 21 is controlled by the action of the control section.

The operation of the sun visor electric slide device having such a configuration is as follows.

First, when the motor 21 is started from the state shown in FIG. 1 and the sprocket 23 fixed to the output shaft 21a of the motor 21 is rotated in the direction B (FIG. 2), the sprocket 23
Based on the meshing action between the tooth portion 23a formed in the hole 27 and the hole 27, the belt wire 25.25 moves to the front side, and the slitter 13 connected to the front end portion of the belt wire 25.25 is attached to the belt wire 25.25. Move to the front side along rail 11.11. Therefore, the sun visor body 17 is
is pushed toward the front side, so that the sun visor main body 17 protrudes from an opening 9a formed at the front end of the interior member 9.

Next, as shown in FIG. 3, when the front end of the sun visor main body 17 reaches the front wind panel 7, the microswitch 31 disposed at the front end of the sun visor main body 17 is activated.
When it comes into contact with the micro switch 3, it turns on and this micro switch 3
The rotation of the motor 21 is stopped based on the signal No. 1. still,
At this time, the main switch of the motor 21 remains on.

Here, when the sun visor main body 17 is moved in the direction of arrow C by manual operation by the occupant, the support rod 15 and the rods 19, 19
The rods 19 and 19 rotate in the A direction about the hinge portion 18 between them, and the sun visor body 17 is suspended from the front surface of the front window panel 7 on the vehicle interior side.

That is, by putting the sun visor main body 17 in such a state of use, the degree of light shielding for the occupant can be sufficiently increased.

Next, when storing the sun visor body 17 to its original state,
When the sun visor body 17 is manually moved upward as shown by the arrow, the micro switch 31
contacts the front wind panel 7 again, and based on the signal obtained from the microswitch 31, a control section (not shown) issues a drive signal to the motor 21 to rotate the motor 21 in the opposite direction to the above-mentioned direction. Sprocket 23
Based on the meshing action between the hole 27 and the belt wire 25, the belt wire 25 moves to the rear side, and the slider 13 connected to the belt wire 25 moves to the rear side along the rail 11.11. supported nine rods 19
, 19, the sun visor main body 17 is pulled toward the rear side and stored in the hollow portion 10. At this time, slider 13
A limit switch 33 attached to the rear end of the rail 1
The movement of the slider 13 is stopped when it comes into contact with a stopper 30.30 provided at the rear end of the slider 13.

That is, when storing the sun visor main body 17, the occupant only has to perform an operation of lifting the sun visor main body 17, which is suspended in the use state, as shown in FIG. 3D.

FIG. 4 is a flowchart in the controller for controlling the protruding and retracting operations of the sun visor body 17. This flow starts from step 101 when the ignition key of the vehicle is turned on. Here, in step 102, the flag N is reset to N=0 as an initial state. In step 103, it is determined whether or not a slide switch provided at a proper location on the vehicle has been turned on by the operation of the occupant. If it has been turned on, the process proceeds to step 201, and if it has not been turned on, the process proceeds to step 104.

In step 201, it is determined whether the beam switch 33 is in the on state. Here the sun visor body 17
If it is in the retracted state, the limit switch 33 is on. If the limit switch 33 is on, proceed to step 202; if it is off, proceed to step 10.
Return to 3.

In step 202, the motor 21 is rotated forward by a predetermined number of rotations, and the sun visor body 17 is moved toward the front wind panel 7 by a predetermined amount.

Furthermore, in step 203, the microswitch 31
It is determined whether or not it is turned on. Step 204 occurs when the microswitch 31 comes into contact with the front wind panel 7 and turns on.
The process proceeds to step 202, and the rotation of the motor 21 is stopped. If the microswitch 31 is turned off, the process returns to step 202, and the motor 21 further rotates at a predetermined number of rotations. Step 2
When the motor 21 is stopped at step 04, the flag N is set to 1 at step 205, and the flow from step 103 onwards is repeated again.

In step 104, it is determined whether or not a retractable switch, which is provided at a suitable location on the vehicle in the same way as a slide switch, has been turned on by the occupant's operation. If the storage switch is on, the process proceeds to step 105, and if the storage switch is off, the process proceeds to step 301. In step 105, it is determined whether or not the microswitch 31 is on. If it is on, the process proceeds to step 106, and if it is off, the process proceeds to step 401. In step 401, a warning such as "Cannot be stored" is displayed on the instrument panel, and the flow from step 103 onward is repeated.In step 106, the motor 21 is reversed by a predetermined number of rotations, and the sun visor body 17 is rotated due to stiffness. moves a predetermined amount to the storage position.In step 107, it is determined whether or not the limit switch 33 is on. If it is on, the rotation of the motor 21 is stopped in step 108, while the limit switch 33 is turned on. If it is off, the process returns to step 106, where the motor 21 is reversed again by a predetermined number of rotations, and the sun visor body 17 is moved by a predetermined amount to the retracted position.After the motor 21 stops in step 108, the process returns to step 102. The following flow is repeated.

In step 301, it is determined whether or not the microswitch 31 is on. If it is on, the process proceeds to step 303, and if it is off, the process proceeds to 302. In step 303, it is determined whether the flag N is O or 1. If it is 1, the process returns to step 103, while if it is 0, the process proceeds to step 106. In step 302, flag N is reset to O, and the flow from step 102 onwards is repeated again.

The operation of the sun visor main body 17 will be explained using the above flow. When the occupant turns on the slide switch with the sun visor body 17 in the retracted position, step 1
03 → 201 → 202 → 203 → causes the motor 21 to rotate forward, and the sun visor body 17
Steps 2°2→203 are repeated, and when the microswitch 31 comes into contact with the front wind panel 7, the motor 21 stops. At this time, the flag N indicating that the sun visor body 17 has slid from the storage position and the microswitch 31 has been turned on has become 1.

When the occupant operates the storage switch in this state, step 103 → 104 → 105 → 106-4107 →
Steps 106 and 107 are repeated, the motor 21 is reversed, the sun visor body 17 is moved to the storage position, and when the sun visor body 17 is retracted and the limit switch 33 is turned on, the motor 21 is turned on in step 10g. 21 is stopped.

On the other hand, from the state in which the sun visor body 17 is slid from the retracted position and the microswitch 31 is turned on,
When the sun visor body 17 is lowered manually, the microswitch 3I is turned off. At this time, step 10
Due to the flow of 3 → 104 → 301 → 302, flag N
is reset to O. At this time, when the sun visor body 17 is moved upward and the micro switch 31 is turned on, steps 103→104→301→303→106→107
Steps 106 and 107 are repeated, the motor 21 is reversed, the sun visor main body 17 is moved to the retracted position, and the motor 21 is stopped at step 10111.

If the sun visor body 17 is hanging down, that is, the microswitch 31 is off, and the occupant turns on the retraction switch, a warning "Cannot be retracted" will be displayed on the instrument panel according to steps 103 → 104 → 105 → 4 old. coming out. The occupant can perform a retraction operation by moving the sun visor body 17 upward based on this display.

Note that even if the occupant turns on the slide switch when the sun visor body 17 is not in the retracted position, steps 103→20
1 is repeated, and the motor 21 is not driven.

In addition, when the sun visor body I7 slides from the retracted state and the microswitch 31 is turned on, and the flag N is set to 1, if neither the slide switch nor the retract switch is turned on, steps 103→104→301
→303 is repeated and the motor 21 is not driven. When the sun visor body 17 is in the retracted position or in the hanging state, and neither the slide switch nor the retract switch is turned on, step 103 → 104 → 3
01 → 302 is repeated, and motor 21 is still
is not driven.

In the above embodiment, the sun visor body 17 is lowered to the front surface of the front window panel 7 on the passenger compartment side and moved upward by manual operation by the occupant, but instead of such manual operation, an electric mechanism is used. It is also possible to cause the above-mentioned lowering and upward movements to be performed based on the following.

In the case of the above embodiment, the contact between the sun visor body 17 and the front wind panel 7 is detected at the front end of the sun visor body 17 to indicate that the sun visor body 17 has changed from the bent state to the extended state. This configuration is equipped with a microswitch 31 as a detection means, and this microswitch 31 is installed at another predetermined part of the slider 13 so that when the sun visor body I7 has finished sliding toward the front side, It is also possible to provide an embodiment in which the same operation as described above is performed by turning on the microswitch 31 between the slider 13 and the rail 11.

By adopting such an embodiment, the microswitch 31 will not collide with the front wind panel 7, and the front wind panel 7 will be prevented from being damaged due to the collision.

Effects of the Invention As explained in detail above, according to the structure of the electric sliding sun visor according to the present invention, the motor is installed in the hollow space formed between the roof panel and the interior member attached to the interior side of the roof. In the electric sliding type sun visor configuration, the sun visor is housed in a sun visor that can freely extend and retract toward the front wind panel from an opening formed in the front of the interior member by the rotational force of the interior member. A bent portion is formed for hanging the sun visor, and a detection means for detecting that the sun visor changes from a bent state to an extended state is provided at a predetermined portion of the sun visor, and a signal obtained from the detection means is Based on this, an electric sliding type sun visor is constructed in which the retracting operation of the sun visor is controlled, so that the following effects are brought about. That is, when the sun visor is not in use, it is stored in the hollow space formed between the roof panel and an interior member attached to the interior side of the roof, making the interior of the vehicle larger and improving the exterior appearance. There is an advantage.

Furthermore, when the sun visor is used, the sun visor is slid toward the front wind panel by the rotational force of the motor, and then the sun visor is suspended from the bent portion to the front surface of the front wind panel on the passenger compartment side by manual operation or the like by the occupant. It is possible to sufficiently increase the degree of light shielding for the occupants.

In addition, when storing the sun visor in its original state, the detection means detects that the sun visor changes from the folded state to the extended state by moving the sun visor upward by manual operation or the like by the occupant. Based on the signal obtained from the means, a drive signal is issued to the motor to rotate the motor in the opposite direction to the direction in which the motor is slid, and the sun visor is stored in the hollow part, so that the occupant can use the sun visor while it is in use. It is only necessary to perform an operation of moving the lever upward toward the roof side, which simplifies the operation and has the advantage of improving safety while driving the vehicle.
