Description

  The present invention relates to a door mirror, and more particularly to a door mirror that prevents or reduces the decrease in temperature inside the vehicle due to the wind near the side window when traveling at high speed.

  As a door mirror for rear confirmation of a vehicle, for example, there is known a door mirror provided with a movable fin which can be rotated outward in the vehicle width direction on a door mirror base (see Patent Document 1).

Japanese Patent Application Publication No. 2007-050761

  In the case of a vehicle having the above door mirror or the like, traveling wind often does not circulate along the vehicle body at the side of the vehicle body behind the door mirror. That is, the aerodynamic characteristics of the vehicle body behind the door mirror were not good.

  On the other hand, there are those in which a door mirror stay protrudes from a door mirror base or a side surface of a vehicle body, and a mirror main body is provided at an end of the door mirror stay. In recent vehicles, traveling wind is often rectified by a door mirror stay and a mirror body. As a result, the traveling wind circulates along the vehicle body at the rear of the door mirror, and good aerodynamic characteristics of the vehicle body at the rear of the door mirror are secured.

  However, when the traveling wind flows along the side window during traveling of the vehicle, heat in the passenger compartment may be taken away by the traveling wind through the side window. This causes a temperature drop near the side window in the vehicle compartment. In particular, since the amount of heat taken away tends to increase when the vehicle is traveling at high speed, the heating efficiency of the vehicle interior is reduced when the outside air temperature is low.

  Therefore, the problem to be solved by the present invention is to provide a door mirror that prevents or reduces the decrease in the temperature inside the vehicle due to the wind in the vicinity of the side window when the vehicle is traveling.

As means for solving the above problems, a door mirror according to the present invention is a door mirror disposed on the side of the vehicle body, and from the front of the front seat and from the side of the vehicle body, the width direction and the vertical direction of the vehicle body Door mirror stay extending along at least one direction, a mirror main body disposed at an end of the door mirror stay, an operating portion which can be projected from the door mirror stay or the mirror main body, and information concerning the temperature outside the vehicle And a controller for causing the operating unit to appear and retreat based on the information related to the traveling speed of the vehicle and the vehicle .

  In the door mirror according to the present invention, it is preferable that the operating portion projects so as to block at least a part of a flow area of traveling wind formed between the vehicle body and the mirror main body in the width direction of the vehicle body.

  In the door mirror according to the present invention, it is preferable that the non-projecting operating part be flush with or substantially flush with an outer surface of the door mirror stay or the mirror main body therearound.

  In the door mirror according to the present invention, it is preferable that the actuating portion projects upward from the lower end of a side window of the vehicle body, which is disposed rearward of the door mirror stay and the mirror main body.

  According to the present invention, by causing the actuating portion to protrude from the door mirror stay or the mirror body, it is possible to disturb the traveling wind in the vicinity of the side window generated when the vehicle is traveling. A door mirror can be provided that prevents or reduces degradation.

  First, the door mirror according to the present invention can be applied to a vehicle in which the traveling wind generated by the traveling of the vehicle may take away heat in the vehicle compartment through the side windows respectively provided on the front door and the rear door. In particular, it is preferable to apply to a vehicle capable of traveling at high speed.

(1) First Embodiment As shown in FIG. 1A, the door mirror 1 includes a door mirror stay 2, a mirror main body 3, and an operating portion 4. The door mirror 1 is disposed to the side of the vehicle body 100, and is used by an occupant of the vehicle 110 to visually recognize the rear.

  As shown to Fig.1 (a), the door mirror stay 2 is a member extended in the substantially width direction of the vehicle body 100 from the front of a front seat and the side of the vehicle body 100. As shown in FIG. The door mirror stay 2 has a substantially rectangular columnar shape, and as shown in FIG. 2 in particular, the longitudinal direction is disposed slightly inclined rearward with respect to the width direction of the vehicle body 100.

  As shown in FIG. 1A, the door mirror stay 2 is attached to the vehicle body 100 via the door mirror base 5. The door mirror base 5 is provided at the lower end portion of the A-pillar 101 and at the front end portion of the front side window 102. The A-pillar 101 is a columnar member provided between the front window 103 of the window member disposed facing the front of the vehicle body 100 and the front side window 102. Further, the front side window 102 is a window member disposed on an upper portion of the front door panel 105 constituting an exterior portion of the front door 104 disposed on the side of the vehicle body 100 and in the front.

As shown to Fig.1 (a), the mirror main body 3 is a member arrange | positioned at the edge part of the door mirror stay 2. As shown in FIG. The mirror main body 3 has a mirror portion 31 in which a mirror surface which allows an occupant to visually recognize the rear side faces the rear, and a cover portion 32 covering the front and the upper side of the mirror portion 31. The cover unit 32 incorporates an actuator used to adjust the angle of the mirror unit 31 and an actuator used to store the door mirror 1 by rotating the mirror main body 3 rearward.
In the present embodiment, the door mirror stay 2 and the mirror main body 3 are formed as separate members, but in the present invention, the door mirror stay 2 and the mirror main body 3 may be integrally formed as long as the above-described shape relationship is satisfied.

  As shown to Fig.1 (a), the action | operation part 4 is a member which can project from the door mirror stay 2. As shown in FIG. In particular, as shown in FIG. 1B, the actuating portion 4 has a cylindrical shape, and can project along the vertical direction of the vehicle body 100 through a hole provided on the upper surface portion of the door mirror stay 2. The operating unit 4 is driven by an electrical signal, and can move forward and backward with respect to the door mirror stay 2. In the present embodiment, the driver of the vehicle 110 performs driving of the actuation unit 4 using the operation input unit 6 described later.

(2) Operation of the actuating portion against traveling wind In FIGS. 2 (a) and 2 (b), the outline of the circulating direction of the traveling wind is shown by thick arrows. In the following, the flow area of the traveling wind formed between the vehicle body 100 and the mirror main body 3 in the width direction of the vehicle body 100, particularly between the vehicle body 100 and the vehicle body 100 width direction inner portion of the cover portion 32 of the mirror main body 3. Is referred to as a forward flow area A indicated by an alternate long and short dash line in FIGS. 2 (a) and 2 (b). Furthermore, a rear circulation area B which is formed behind the front circulation area A and which shows a circulation area in the vicinity of the rear seat of the traveling wind along the vehicle body 100 is shown by a two-dot chain line in FIGS. I assume. In addition, although the front distribution area A and the rear distribution area B show only a plan view as shown in FIGS. 2A and 2B, in the area formed from the upper end to the lower end of the vehicle body 100 is there.

  When the actuating portion 4 is not driven, that is, when the actuating portion 4 is in a non-projecting state as shown in FIG. 1A, the vehicle 110 is traveling, as shown in FIG. The traveling wind circulating in the region B circulates along the rear side window 107 of the rear door 106. In particular, when the vehicle 110 is traveling at a high speed, the traveling wind at the side of the vehicle body 100 circulates so as to stick to the rear side window 107.

  When the temperature outside the vehicle compartment is relatively lower than that of the vehicle interior of the vehicle 110, the traveling wind flowing along the rear side window 107 takes heat in the vehicle compartment via the rear side window 107. Thus, the vehicle 110 radiates heat to the outside through the rear side window 107 by traveling, and as a result, the temperature in the passenger compartment is lowered.

  In addition, as the traveling speed of the vehicle 110 increases, the amount of heat in the passenger compartment taken away by the traveling wind also increases. In particular, when the vehicle 110 travels at a high speed, the traveling wind adheres to the rear side window 107 as described above, so the amount of heat in the passenger compartment taken away by the traveling wind becomes very large. When the outside temperature is low as the traveling environment of the vehicle 110, when the vehicle 110 travels at a high speed, the temperature in the vicinity of the rear side window 107 in the vehicle compartment is greatly reduced. In this case, the heating efficiency of the vehicle interior is reduced.

  Since the traveling wind also circulates along the front side window 102 of the front door 104, the temperature near the front side window 102 in the vehicle compartment also decreases. However, when the vehicle 110 travels at a high speed, the amount of heat in the passenger compartment taken away via the rear side window 107 rather than the front side window 102 tends to be larger.

In conventional door mirrors, there have been vehicles in which traveling wind is not rectified by the door mirror stay 2 and the mirror body 3. In this case, a large amount of heat in the passenger compartment was rarely lost by the traveling wind through the side window. In such a conventional vehicle, the door mirror stay 2 is not often provided.
On the other hand, in the door mirror 1 according to the present embodiment, traveling wind is rectified by the door mirror stay 2 and the mirror main body 3. As a result, the aerodynamic characteristics of the vehicle body 100 are improved, and the fuel consumption can be improved. However, when the outside temperature is low and the vehicle 110 travels at a high speed, excessive rectification of the traveling wind by the door mirror stay 2 and the mirror main body 3 causes the side window between the traveling wind and the vehicle interior to Extensive heat exchange occurs.

  When the actuating portion 4 is driven, that is, when the vehicle 110 in which the actuating portion 4 is in a projecting state as shown in FIG. The circulating traveling wind circulates away from the rear side window 107. As shown in FIG. 1 (b), the actuating portion 4 protrudes so as to block a part of the front flow area A, so as shown in FIG. 2 (b), the traveling wind flowing in the front flow area A acts The speed of the traveling wind decreases, and the flow direction of the traveling wind becomes unstable and disturbed. As a result, a pressure change occurs at each position in the back and forth direction of the vehicle body 100 in the traveling wind flowing along the rear side window 107 in the rear circulation region B, so the traveling wind flows away from the rear side window 107 become. Therefore, the amount of traveling wind near the rear side window 107 in the rear flow area B is reduced, so the amount of heat taken from the vehicle interior by the traveling wind via the rear side window 107 is also reduced. As a result, it is possible to prevent or reduce the decrease in the temperature of the passenger compartment caused by the traveling wind.

  In the present embodiment, a part of the front circulation area A that may greatly affect the direction, the amount, and the like of the traveling wind flowing in the rear circulation area B is blocked by the protruding operation unit 4. In other words, when the actuating portion 4 protrudes when the vehicle body 100 and the door mirror 1 in the vehicle 110 are viewed from the front, a part of the contour of the door mirror stay 2 between the mirror main body 3 and the vehicle body 100 changes and protrudes . Thereby, the traveling wind which circulates near rear side window 107 in back distribution field B can be disturbed efficiently. As a result, it is possible to more reliably prevent or further reduce the decrease in the temperature of the passenger compartment caused by the traveling wind.

  Further, in the present embodiment, the actuating portion 4 projects upward from the lower end of the rear side window 107. In other words, since the actuating portion 4 protrudes at substantially the same height as the rear side window 107, the flow of the traveling wind in the rear flow area B is easily disturbed. That is, the actuating portion 4 protrudes not on the lower surface portion of the door mirror stay 2 positioned substantially at the same height as the front door panel 105 but on the upper surface portion of the door mirror stay 2 positioned above the lower ends of the front side window 102 and the rear side window 107 Do. That is, the actuating portion 4 and the rear side window 107 are disposed at overlapping positions when the vehicle body 100 is viewed from the side. As a result, the traveling wind flowing along the rear side window 107 rather than the door panel located below the rear door 106 in the rear flow area B is easily disturbed. By optimizing the projecting direction, the projecting amount, and the like of the actuating portion 4, it is possible to make the rear side window 107 hardly collide with the traveling wind. Therefore, according to the present embodiment, it is possible to more reliably prevent or further reduce the decrease in the temperature of the passenger compartment due to the traveling wind through the rear side window 107.

  Furthermore, in the present embodiment, the operating portion 4 is provided on the door mirror stay 2 in the vertical direction of the vehicle body 100, as is particularly clear from FIG. It projects only up to about the same position or a position lower than the upper end of the cover 32. This is preferable because the view of the door mirror 1 and the vicinity thereof when the passenger looks at the outside of the vehicle compartment from the vehicle interior is not or hardly obstructed.

  In the present embodiment, the angle adjustment of the mirror unit 31 and the drive of the actuating unit 4 can be controlled independently. As a result, even when the actuating portion 4 is driven, there is no deviation in the rear view angle by the occupant via the mirror portion 31, and control of the complicated position and angle of each member, and complication related to the control Operation is unnecessary.

  As shown in FIG. 1, in the present embodiment, the operating unit 4 is provided on the door mirror stay 2. In many cases, an appropriate actuator for adjusting the angle of the mirror section 31, a wire, a lead, etc. is disposed inside the door mirror stay 2, so providing the drive mechanism of the actuating section 4 together is a substantial design. It is easy without any change. In addition, there is no restriction | limiting in particular as a drive mechanism of the action | operation part 4, For example, any of an electric type and hydraulic type may be sufficient.

  The actuating portion 4 is formed such that its tip end surface and the outer surface of the door mirror stay 2 around the actuating portion 4 are substantially flush when in the non-projecting state shown in FIG. 1A. Thus, the aerodynamic characteristics of the vehicle body 100 are not degraded when the actuating portion 4 is not protruded. Therefore, good aerodynamic characteristics of the vehicle body 100 when the actuating portion 4 does not protrude, good fuel consumption of the vehicle 110, and prevention or reduction of a decrease in the vehicle interior temperature due to traveling wind when the actuating portion 4 protrudes are obtained. Be

(3) Drive Control of Actuation Unit Here, drive control of the actuation unit 4 will be described with reference to FIGS. 3 and 4.
FIG. 3 is a block diagram showing a control system of the actuation unit 4. FIG. 4 is a flowchart relating to the driving of the operating unit 4.

  The protrusion of the operation unit 4 operates the operation input unit 6 such as a push button, an operation lever, or a touch panel under an environment where heat in the vehicle compartment is taken away by the traveling wind flowing along the side window via the side window. Done by As such an environment, for example, an environment in which the outside air temperature is low and the vehicle 110 is traveling at a high speed can be mentioned.

  As shown in FIG. 3, in the control system of the operating unit 4 in the present embodiment, the controller 9 generates a signal based on the operation input to the operation input unit 6 and the air temperature outside the vehicle detected by the outside air temperature sensor 7. Such a signal and a signal relating to the traveling speed of the vehicle 110 detected by the speed sensor 8 are input. Further, the controller 9 can output a drive signal to the operating unit 4, and can display the temperature outside the vehicle, the traveling speed of the vehicle 110, and the operating unit with respect to the display unit 20 having a display or the like disposed in the vehicle. It is possible to output a signal for displaying the driving state of 4 and the like. When a signal based on an operation is input from the operation input unit 6, the controller 9 in the present embodiment can output a drive signal to the operation unit 4. The drive control of the operation unit 4 is, for example, as shown in FIG.

  As drive control of the operation unit 4, first, it is determined whether the temperature outside the vehicle compartment is lower than a predetermined temperature (step S1). At this time, the operating unit 4 is in the non-projecting state shown in FIG. The outside air temperature sensor 7 sequentially inputs a signal relating to the air temperature outside the vehicle to the controller 9. The controller 9 can determine the level of the temperature outside the vehicle and the predetermined temperature by comparing the predetermined temperature set in advance with the temperature outside the vehicle.

  The predetermined temperature is set to a temperature at which the occupant feels that heating is necessary, and is appropriately set in consideration of, for example, the clothes of the occupant, the temperature of the vehicle interior that the occupant feels appropriate, and the temperature difference between the vehicle interior and the vehicle exterior. Be done.

  If the temperature outside the passenger compartment is higher than the predetermined temperature (NO in step S1), the occupant will be in the passenger compartment even if the traveling air flowing through the rear circulation region B removes heat from the passenger compartment through the rear side window 107. It is not necessary to drive the operating part 4 because it does not feel or does not feel that heating is necessary.

  When the temperature outside the passenger compartment is lower than the predetermined temperature (YES in step S1), the amount of heat generated by the traveling wind flowing through the rear circulation region B from the passenger compartment through the rear side window 107 is large. As a result, the temperature in the passenger compartment can be easily reduced.

  Next, it is determined whether the traveling speed of the vehicle 110 is higher than a predetermined speed (step S2). At this time, the actuating portion 4 maintains the non-projecting state shown in FIG. The speed sensor 8 sequentially inputs a signal relating to the traveling speed of the vehicle 110 to the controller 9. The controller 9 can determine the magnitude between the traveling speed of the vehicle 110 and the predetermined speed by comparing the predetermined speed set in advance with the traveling speed of the vehicle 110.

  The predetermined speed is set to a speed at which heat can be taken from the vehicle interior by the traveling wind flowing through the rear circulation region B and the vehicle interior can feel cold. As the predetermined speed, for example, a speed at which a large temperature drop in the vicinity of the rear side window 107 in the vehicle compartment may occur due to a traveling wind to cause a reduction in heating efficiency of the vehicle compartment, a material and thermal conductivity of the rear side window 107, and speed bands In consideration of the aerodynamic characteristics and the like of the vehicle body 100 in the rear flow area B in the above, it is appropriately set.

  When the traveling speed of the vehicle 110 is slower than the predetermined speed (NO in step S2), the amount of heat taken from the vehicle interior through the rear side window 107 by the traveling wind flowing through the rear flow area B is small. Specifically, although the temperature outside the passenger compartment is low, traveling wind is circulating in the rear circulation area B when the vehicle 110 is stopped and when the vehicle 110 is traveling at a relatively low speed. There is no, even if it is in circulation, the speed of the traveling wind is slow. As a result, heat exchange via the rear side window 107 is difficult to be performed between the vehicle exterior and the vehicle interior, and as a result, the amount of heat taken from the vehicle interior by the traveling wind is reduced.

  Therefore, in this case, since the temperature decrease in the vehicle interior caused by the traveling wind, particularly the temperature decrease in the vicinity of the rear side window 107, is small, there is no need to drive the operating portion 4. At this time, even if the temperature in the passenger compartment is lowered, the temperature drop is small, and by operating the heating device in the passenger compartment, it is possible to easily realize the in-vehicle environment in which the occupant feels appropriate temperature. That is, even when the air temperature outside the vehicle compartment is lower than the predetermined temperature, if the traveling speed of the vehicle 110 is lower than the predetermined speed, the heating efficiency of the vehicle interior does not decrease or the decrease width is small. There is no need to drive

  When the traveling speed of the vehicle 110 is faster than the predetermined speed (YES in step S2), the amount of heat taken from the vehicle interior through the rear side window 107 by the traveling wind flowing through the rear flow area B is large. When the vehicle 110 is traveling at a high speed, the speed of the traveling wind circulating in the rear distribution area B also increases. Furthermore, since the vehicle 110 in recent years is designed to improve the aerodynamic characteristics of the vehicle body 100 as the traveling speed increases, it travels so as to stick to the rear side window 107 when the vehicle 110 travels at high speed. As a result, heat exchange via the rear side window 107 is continuously and efficiently performed between the passenger compartment and the passenger compartment, and as a result, the amount of heat taken from the passenger compartment increases.

  Therefore, in this case, since the temperature drop in the vehicle compartment, particularly the temperature drop in the vicinity of the rear side window 107, is large, the ideal heating efficiency can not be obtained even if the heating is driven in the vehicle compartment, and the operating unit 4 is driven. A need arises.

  Next, the operating unit 4 is protruded (step S3). Specifically, the specific condition that the temperature outside the vehicle compartment is lower than the predetermined temperature (YES in step S1) and the traveling speed of the vehicle 110 is faster than the predetermined speed (YES in step S2) is satisfied. When the occupant of the vehicle 110 performs an operation of driving the operating unit 4 through the operation input unit 6 illustrated in FIG. 3, the operating unit 4 to which the electric signal related to the driving is input from the controller 9 is shown in FIG. It projects from the door mirror stay 2 as shown in b).

  As described above, if the temperature decrease in the passenger compartment via the rear side window 107 does not affect the heating efficiency or is small, the passenger compartment can be maintained at an appropriate temperature by driving the heating device or the like. Furthermore, by projecting the working part 4 under the specific conditions described above, it is possible to eliminate or improve a situation where it is difficult to obtain the ideal heating efficiency.

  That is, the aerodynamic characteristics of the vehicle body 100 intended for designing the vehicle 110 in the front circulation area A and the rear circulation area B, in particular, by maintaining the actuating part 4 in the non-projecting state except for the above-mentioned specific conditions By realizing the fuel consumption and the like of the vehicle 110 and making the operating unit 4 in a projecting state under specific conditions, it is possible to substitute part of the aerodynamic characteristics and the fuel consumption and the like with the improvement of the heating efficiency of the vehicle interior. The vehicle interior environment can be realized.

(4) Second Embodiment Next, a modification of the present invention will be described with reference to FIG.
FIG. 5 is a perspective view schematically showing a door mirror 10 according to another embodiment of the present invention, and FIG. 5 (a) is a perspective view schematically showing the door mirror 10 in which the actuating portion 40 is not projected. 5 (b) is a perspective view showing an outline of the door mirror 10 in a state in which the actuating portion 40 is in a projecting state.

  In the embodiment shown in FIG. 5, a door mirror stay 21 is used in place of the door mirror stay 2 and the operating portion 4 in the embodiment shown in FIG. In the other points, since the same members are used, the same reference numerals are given and detailed description will be omitted.

  As shown in FIGS. 5A and 5B, the door mirror stay 21 is formed by bending a rod-like member having a substantially rectangular column shape. More specifically, the door mirror stay 21 includes a first extension portion 211 extending from the door mirror base 5 toward the outer side of the vehicle body 100 in the substantially width direction, and an outer portion substantially in the width direction from the tip of the first extended portion 211. And a second extending portion 212 extending substantially upward. The cover 32 in the mirror body 3 is provided at the tip of the second extension 212. The operating portion 40 is provided at a portion of the second extending portion 212 of the door mirror stay 21 facing the inner side in the width direction of the vehicle body 100.

  As shown in FIG. 5 (b) in particular, the actuating portion 40 can project from the second extending portion 212 toward the inner side and the substantially upper direction in the width direction of the vehicle body 100. When the actuating portion 40 protrudes, a part of the flow area of the traveling wind formed between the vehicle body 100 and the mirror main body 3 and the second extending portion 212 is blocked. This disrupts the flow of part of the traveling wind. If the circulation of a part of the traveling wind is disturbed, the traveling wind whose operating part 40 disturbs the circulation does not circulate along the vehicle body 100 in the circulation area and the backward circulation area B of the traveling wind shown in FIG. 2 Or it becomes difficult. Therefore, in the rear circulation area B of the traveling wind, the amount of the traveling wind taking away heat in the vehicle compartment is reduced. As a result, it is possible to prevent or reduce the temperature decrease in the passenger compartment due to the traveling wind through the rear side window 107.

  In the embodiment shown in FIG. 5, the position at which the actuating portion 40 is provided in the vertical direction of the vehicle body 100 is higher than the position of the actuating portion 4 in the embodiment shown in FIGS. Thereby, the embodiment shown in FIG. 5 can disturb the flow of the traveling wind at a position higher in the vertical direction of the vehicle body 100 as compared with the embodiment shown in FIG. 1 etc. It is possible to prevent or reduce the temperature decrease in the passenger compartment caused by the traveling wind flowing through a higher position.

  Further, in the embodiment shown in FIG. 5, as in the embodiment shown in FIGS. 1 to 4, the door mirror stay 21 is provided with the actuating portion 40, and the actuating portion 40 is the mirror body 3 in the vertical direction of the vehicle body 100. By projecting only to a position substantially the same as or lower than the cover portion 32, it is preferable because it does not obstruct the visibility of the door mirror 10 and its vicinity when the occupant looks out of the vehicle interior from the vehicle interior. .

(5) Other Modifications As far as the object of the present invention can be achieved, the present invention can adopt various modifications other than the embodiment shown in FIGS.

  As a modification of the embodiment described above, the position where the door mirror stay 2 is attached may be the front door panel 105 instead of the front side window 102 as in the embodiment shown in FIG. 1, for example. Basically, the mirror body 3 is disposed at substantially the same height as the side window, and it is possible to disturb the flow of the traveling wind by the projection of the actuating portion 4, so the members to which the door mirror stay 2 is attached and the attachment positions are limited. There is no.

  As still another modification, for example, an embodiment in which the door mirror base 5 is not provided can be mentioned. Depending on the design of the vehicle 110, the door mirror stay 2 may be attached to the front door panel 105. In this case, the operating portion 4 may be disposed on the door mirror stay 2 or the mirror body 3 without providing the door mirror base 5. .

  As another modification, the extending direction of the door mirror stay may be a direction toward at least one of the width direction outer side and the upper direction of the vehicle body, for example, extending substantially upward from the front side window or front door panel It is good.

  In the control mode of the operation unit 4 shown in FIG. 4, as long as the above-described specific condition can be detected, the process (step S1) of determining whether the air temperature outside the vehicle is lower than a predetermined temperature; The order of the step (step S2) of determining whether the traveling speed of the vehicle is greater than the predetermined speed may be reversed.

  Further, in the embodiment shown in FIG. 4, each information related to the outside temperature and traveling speed of the outside of the vehicle is sequentially input to the controller 9, but for example, any information of outside temperature and traveling speed of the outside of vehicle The information necessary for the other process is input to the controller 9 when the information input sequentially satisfies the comparison condition with the predetermined temperature or the predetermined speed and the result of one process becomes YES. You may start.

  Furthermore, in the control system related to the driving of the operating unit 4 shown in FIG. 3, a manual operation using the operation input unit 6 is performed based on the information related to the temperature outside the vehicle and the traveling speed displayed on the display unit 20 by the occupant. Is doing. Instead of providing the operation input unit 6, for example, the controller 9 automatically performs the door mirror of the operation unit 4 based on the temperature outside the vehicle, the traveling speed, and a predetermined value set in advance, without providing the operation input unit 6. You may employ | adopt the form made to advance or retreat with respect to the stay 2 or the mirror main body 3. FIG.

  In the embodiment shown in FIGS. 1 to 5, the flow amount and the flow direction of the traveling wind in the rear flow area B change in accordance with the protrusion distance of the operation parts 4 and 40. Therefore, it is preferable to previously determine the projection distance of the operation parts 4 and 40 which disturb the traveling wind so as to be most separated from the rear side window 107 by a test or the like.

  Instead of providing one cylindrical member shown in FIGS. 1 to 5 as the operating part of the present invention, for example, a form in which a plurality of columnar members are arranged in a row along the vehicle width direction is adopted. can do. The amount and direction of circulation of the traveling wind in the rear circulation region B are changed by changing the columnar members to be protruded and the projection distance and the like. Situations such as the case where the amount of heat radiation through the front side window 102 is large, the case where the amount of heat radiation through the rear side window 107 is large, and the case where the heat radiation amount through the front side window 102 and the rear side window 107 is equally large Accordingly, the traveling wind at any position in the rear flow area B can be disturbed and distributed away from the vehicle body by appropriately adjusting the protrusion form of the actuating portion.

  In addition, when the occupant is seated only in the front seat, the occupant may not feel cold or hardly feel cold even if a temperature drop due to the traveling wind occurs near the rear side window 107 in the vehicle interior. In this case, the traveling wind that disturbs the circulation may be changed as compared with the case where the occupant is seated in the front seat and the rear seat. That is, when the occupant is seated only in the front seat, it is not essential to disturb the traveling wind flowing in the vicinity of the rear side window 107. Therefore, the modification which provides a sensor which detects a passenger | crew in the front seat and back seat which a passenger | crew seats, or the appropriate position in a vehicle interior can be mentioned. The sensor detects that the occupant is seated only in the front seat, and when the air temperature outside the vehicle compartment is lower than a predetermined temperature and the vehicle is traveling at a speed higher than a predetermined speed, the front side window 102 is used. It is only necessary to project the operating part 4 so as to disturb only the circulating wind.

  Although the embodiment to which the invention made by the inventor has been applied has been described above, the present invention is not limited by the description and the drawings that form a part of the disclosure of the present invention according to this embodiment. For example, although the auxiliary member has a disk shape or a cylindrical shape in the embodiment, it may have another shape. That is, it is needless to say that it is needless to say that all other embodiments, examples, operation techniques and the like made by those skilled in the art based on this embodiment are included in the scope of the present invention.
