Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to a door mirror for an automobile, and more particularly to a retractable door mirror equipped with a water droplet removing device for removing water droplets adhering to the surface of the mirror by blowing air onto the surface of the mirror. .

[Conventional technology]

Conventionally, door mirrors have been provided that are equipped with a device for removing water droplets in order to prevent visibility behind the vehicle from being reduced due to water droplets adhering to the surface of the door mirror when driving a car during rain. ing. An example of this is a door mirror equipped with a water droplet removing device that can remove water droplets by blowing air onto the surface of the mirror. In such door mirrors, the water droplet removal device generally consists of an air compressor installed inside the vehicle body and an air blowing nozzle installed around the mirror body connected by a tube, so that air can be removed from the blowing nozzle to the mirror surface. It is constructed so that it can be sprayed on.

[Problem to be solved by the invention]

By the way, recently, in many door mirrors, in order to reduce the width of the vehicle when parked, the visor, which is a casing that holds the mirror body in a tiltable manner, rotates around an axis provided on a stay that is fixed to the door. By being movably mounted, the mirror is configured as a so-called retractable type so that the use position and storage position of the mirror can be selectively set. If you configure the door mirror as a retractable type like this and install a water drop removal device to remove water droplets from the mirror surface using air as described above, it will be difficult to process the tube that must be passed from the inside of the vehicle body to the inside of the visor. A problem arises. In other words, conventionally, the shaft that rotatably holds the visor has been formed hollow, and a wire harness that connects the visor storage mechanism, mirror tilting mechanism, etc. to the battery is passed through the shaft in order to operate the visor storage mechanism, mirror tilting mechanism, etc. However, a problem arises in that it is extremely difficult to pass a tube to further supply air inside this hollow shaft, considering the space involved. In order to pass the tube through the hollow shaft, design restrictions such as increasing the shaft diameter arise. On the other hand, it is clear that passing the tube anywhere other than inside the hollow shaft is not preferable, since this may cause the tube to twist or bulge when the visor is retracted or raised. Therefore, the tube is divided into two parts at the boundary between the stay and the visor, and the two parts are automatically connected only when the visor is in the position where the mirror is used, or when air is blown onto the mirror surface. It is conceivable to connect using a connector. However, with this configuration, when the visor is in the retracted position or when air is not blown to the mirror surface, there is a risk that water or dust may enter between the disconnected connectors. The tube that connects the connector and the air supply source installed inside the vehicle body goes down inside the door and then passes through the inside of the bonnet, etc., as shown in Figure 5, which shows the outline of the piping route. If water enters the tube inside the door, it will enter the tube inside the door. Therefore, the water droplets on the mirror surface cannot be removed neatly, and on the contrary, the mirror surface becomes dirty.Therefore, the technical problem to be solved by the present invention is to remove the water droplets from the stay and visor. By preventing water from entering the tube from the connector that connects the tube divided into two at the boundary only when necessary, water droplets on the mirror surface can be reliably removed by air blowing even in retractable door mirrors. It is to do so.

[Means to solve the problem]

According to the present invention, the present invention includes a stay that is fixed to a door of a vehicle body, and a visor that is attached to the stay so that the use position and storage position of the mirror can be set. A door mirror for an automobile equipped with a water droplet removing device having a supply source, an air blowing nozzle provided around the mirror body to blow air onto the surface of the mirror body, and a tube connecting the air supply source and the blowing nozzle. A door mirror is provided which is characterized by the following configuration. That is, the tube is composed of a first tube located closer to the air supply source than the boundary position between the stay and the visor, and a second tube located closer to the air blowing nozzle side than the boundary position. 1. The second tubes are connected to each other via a connector consisting of a first connector member and a second connector member. The first connector member includes a housing to which the first tube is connected and held by the stay facing the visor, a mover held movably toward the visor within the housing, and a mover that is connected to the visor. and a spring means for biasing it in a direction away from. and,
The mover includes a pressure receiving part having a pressure receiving surface formed substantially perpendicular to the moving direction of the mover to be pressed by air supplied through the first tube, and a spring means for compressing the air that presses the pressure receiving surface. The housing includes an engaging portion that protrudes from the housing by moving the mover toward the visor against the urging force of has a closing part that comes into contact with the periphery of the opening on the pressure receiving surface side of the communication hole formed in the slider and closes the opening when the slider is biased by the spring means and separated from the visor. There is. Further, the second connector member is held by the visor so as to face the first connector member when the second tube is connected and the visor is in the mirror use position, and the second connector member is engaged with the mover protruding from the housing. It has a communication part which fits into the part and allows communication between the communication hole of the mover and the conduit of the second tube.

[Action/effect]

In the above configuration, when air is not supplied from the air supply source, the mover is biased by the spring means and moves away from the visor, so the engaging portion does not protrude from the housing and has an arch inside. It will be in a locked state. Therefore, if you do not blow air onto the mirror surface,
The visor can be freely set to the mirror usage position and storage position. Further, at this time, the opening of the communication hole formed in the slider on the pressure receiving part side comes into contact with the closing part formed in the housing and is closed. Therefore, although the connector is disconnected and the communication hole is open to the outside, water and the like will not enter into the tube from between. On the other hand, when removing water droplets from the mirror surface with the visor or mirror set in the use position, the air sent from the air supply source causes the pressure receiving surface of the pressure receiving part formed on the mover to By pressing with a force stronger than the force, the mover moves toward the visor. As a result, the engaging portion of the mover protrudes from the housing and fits into the communication portion of the second connector member, and the conduit of the first tube and the conduit of the second tube are connected through the communication hole of the mover. Let's communicate. Therefore, the air can pass from the conduit of the first tube through the communication hole of the slider to the conduit of the second tube, and furthermore, the air that has proceeded to the second tube is transferred from the Suita nozzle to the mirror. It is blown out towards the surface. With this configuration, as mentioned above, water will not enter the tube even when the connector is disconnected.
Even if water gets in, it stays in the communication hole, so even when air is blown out, only a small amount of water is blown out in the form of a mist. Therefore, since only air is immediately blown onto the surface of the mirror, water droplets adhering to the surface of the mirror can be neatly removed by the air as intended. In addition, in the above configuration, the mover moves to the visor side and connects the first tube and the second tube only when air should be blown out, and at other times the connector is always disconnected. , this connector is usually not an obstacle when setting the visor position, and
Therefore, problems such as tube collapse do not occur. In this way, according to the above configuration, air can be blown onto the surface of the mirror when necessary while preventing water from entering the tube, making it possible to remove water droplets from retractable door mirrors by blowing air. becomes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An automobile door mirror equipped with an air-blown water droplet removing device according to an embodiment of the present invention shown in FIGS. 1 to 4 will be described in detail below. FIG. 1 is a front view of this door mirror, and FIG. 2 is a plan view. As shown in the figure, this door mirror is composed of a stay l fixed to the door of the vehicle body, and a visor 2 that tiltably supports a mirror holder 21 that holds a mirror body 20. The mirror is held on the stay 1 so that it can be set at either the use position or the storage position where the surface of the mirror body 20 is approximately parallel to the side window. The mirror holder 21 is provided with a blowing nozzle 22 for blowing air onto the surface of the mirror body 20. Air is sent to this nozzle 22 from an air supply source (not shown) provided inside the vehicle body through a tube 6.7, thereby removing water droplets that adhere to the surface of the mirror during rain or the like. It is configured as follows. This tube 6.7 includes a first tube 6 that is passed closer to the air supply source side than the boundary position between the stay 1 and the visor 2, and a first tube 6 that is passed closer to the air supply source side than the boundary position between the stay 1 and the visor 2;
It is composed of a second tube 7 that is passed through the second side,
Each tube 6.7 is interconnected via a connector 5 provided at its border position. The configuration of this connector 5 will be explained using the cross-sectional view shown in FIG. As shown in the figure, this connector 5 is composed of a first connector member 3 and a second connector member 4. The first connector member 3 includes housings 8 and 9 consisting of a generally cylindrical housing body 9 and a cap member 8 having an air inlet boat 8a, and a visor inside a storage recess 10 formed in the housing 8.9. The moving element 11 is mounted so as to be movable in two directions, and a compression spring 13 biases the moving element 11 in a direction away from the visor 2. The housing body 9 has a plate spring-like attachment portion 9a formed on its outer peripheral surface connected to a hole 1a formed in the stay l.
It is attached to the stay 1 by passing it through. The mover 11 includes a pressure receiving part 11b into which the sealing gasket 12 is fitted and which fits into the storage recess lO, and an engaging part formed to have a smaller diameter than the pressure receiving part 11b and whose tip end is tapered. 11c, and a communication hole 11d is formed inside thereof along the moving direction of the mover 11. The first tube 6 side of the pressure receiving part 11b is formed as a pressure receiving surface 11e that is substantially perpendicular to the moving direction of the slider 11, and the area around the communication hole 11d in the pressure receiving surface 11e is formed as an annular protrusion 11a. It is formed. A cap member 8 is provided on the opposite side of the housing body 9 to the visor.
is fixed. The first tube 6 is connected to an inlet boat 8a formed in the cap member 8. Further, when the movable element 11 is biased by the compression spring 13 and is separated from the visor 2, the protrusion 11 of the movable element 11
a to close the opening of the communication hole 11d,
A rubber gasket 17 is attached to the center portion of the cap member 8 to form a closing portion. On the other hand, a plate 16 is fixed to the second connector member 4 at a position opposite to the stay, and after inserting the second tube 7 through the hole 16a of this plate 16,
The second tube 7 is prevented from being pulled out by attaching a pin 5 that is somewhat longer than the diameter of the hole 16a. Further, at a position on the stay side of the second connector member 4, a rubber hole 14a having a diameter approximately the same as the diameter of the tapered portion of the engaging portion 11c of the mover 11 is formed. The knoll material 14 is the first. Concave portion 4a formed as a communicating portion for communicating the conduit of the second tube 6.7
is installed on. In this configuration, the mover 11 typically has a spring means 1
3 toward the cap member 8, the engaging portion 11c is accommodated in the housing 9. Therefore, the first connector member 3 and the second connector member 4
Since the mirrors are kept separated from each other, the visor 2 can be freely set from the storage position of the mirror to the use position or from the use position to the storage position. Ma1ko,
At this time, the communication hole 11d is inserted between each connector member 3.4.
It is conceivable that water or the like may enter the tank, but since the protrusion 11a formed on the slider 11 is in contact with the gasket 17 provided on the cap member 8, the water or the like remains in the communication hole 11d. It does not proceed to the first tube 6 from there. In addition, when removing water droplets attached to the surface of the mirror, by sending air from a supply source, the air presses the pressure receiving surface 11e of the slider +1, pushes the slider 11 toward the visor 2 side, and engages the Connect the joint 11c to the housing 9
protrude from Therefore, the tapered portion at the tip of the engaging portion 11c protruding from the housing 9 comes into contact with the sole material I4 provided on the second connector member 4, and is formed inside the mover 11, as shown in FIG. Communication hole L1. d
The channels of the first tube 6 and the second tube 7 communicate with each other through the tube. As a result, the air sent out from the supply source further passes through the second tube 7 from the communication hole 11d to the blowing nozzle 22, and is blown from there toward the surface of the mirror to remove water droplets attached to the surface of the mirror. do. Note that even if water has entered the inside of the communication hole 11d, only a small amount will be blown out in the form of mist, and soon only air will be blown out, so water droplets attached to the mirror surface will be blown out. can be removed cleanly. As described above, in this embodiment, since the connector 5 is normally disconnected, the position of the visor can be set freely, and if necessary, air can be blown onto the surface of the mirror to remove water droplets. Can be removed.
