Japanese Patent No. 5936288 JP 2008-168715 A

  In the outer mirrors of Patent Documents 1 and 2, since the camera is fixed to the mirror housing, an external impact is easily input to the camera, and the housing is expanded more than a normal shape in order to secure a camera installation space. The outer shape of the normal outer mirror without a camera is different. For example, the outer mirrors of Patent Documents 1 and 2 have a problem that the orientation of the camera is easily changed when an external impact is input to the camera. For example, the outer mirror of Patent Document 1 has a problem in that since the lower portion of the mirror housing swells, the projected area of the vehicle increases and the air resistance during vehicle travel increases.

  Therefore, an object of the present invention is to provide an outer mirror for a vehicle that can reduce the degree of change in outer shape and can reduce the input of an impact to the camera.

  An outer mirror of a vehicle according to an aspect of the present invention is an outer mirror of a vehicle that enables visual recognition at the rear of the vehicle, the mirror member having a mirror surface, and the mirror surface facing the rear of the vehicle. A mirror support that supports the mirror member from the back side of a mirror surface; a skeleton member to which the mirror support is attached and coupled to a vehicle body; and an objective unit that is directed toward the rear of the vehicle and includes a lens, A camera attached to a skeleton member; a housing covering each of the mirror support, the skeleton member, and the camera in a state where the mirror member is exposed; and the vehicle formed so as to surround the periphery of the mirror member. A visor unit coupled to the housing from a rear side, and the visor unit includes an inner side of the housing And a hollow elastic member that covers the periphery of the through hole so as to make a round and projects to the inner side and the outer side is provided.

  As shown in FIG. 1, the vehicle 1 is configured as a four-wheeled passenger car. 1 and other drawings, arrow Fr indicates the front of the vehicle, arrow Rr indicates the rear of the vehicle, arrow R indicates the right side of the vehicle, L indicates the left side of the vehicle, U indicates the upper side of the vehicle, and D indicates the lower side of the vehicle. A pair of left and right outer mirrors 3 are provided on the vehicle body 2 of the vehicle 1 as door mirrors so as to be movable together with the left and right vehicle doors 4. Each outer mirror 3 enables a passenger to visually recognize the rear of the vehicle, and incorporates a camera 13 that captures the rear of the vehicle. Since each outer mirror 3 has a bilaterally symmetric configuration, the following description will be given with respect to the outer mirror 3 on the right side of the vehicle.

  As shown in FIGS. 2 and 3A to 3C, the outer mirror 3 includes a mirror member 10 having a mirror surface 10a, a mirror support 11 that supports the mirror member 10, and a skeleton member 12 to which the mirror support 11 is attached. Formed so as to surround the periphery of the mirror member 10 and the housing 15 covering each of the mirror support 11, the skeleton member 12, and the camera 13 with the camera 13 attached to the skeleton member 12 and the mirror member 10 exposed. And a visor portion 16 coupled to the housing 15 from the vehicle rear side.

  As shown in FIGS. 3A and 3B, the mirror member 10 has a base 20 that covers the back side of the mirror surface 10 a, and the base 20 is fixed to the mirror support 11. The mirror support 11 supports the mirror member 10 from the back side of the mirror surface 10a so that the mirror surface 10a is directed to the rear of the vehicle. The mirror support 11 includes a fixing portion 21 attached to the skeleton member 12, a coupling portion 22 coupled to the base 20 of the mirror member 10, and an electric actuator 23 interposed between the fixing portion 21 and the coupling portion 22. It has. The actuator 23 is provided to adjust the direction of the mirror member 10 in the vertical and horizontal directions as indicated by the arrows in the figure, and is held by the fixed portion 21.

  The skeleton member 12 is coupled to the vehicle body 2 with an electric rotating mechanism 25 for folding the outer mirror 3 interposed when the vehicle 1 is parked. The rotating mechanism 25 is fixed to the skeleton member 12 and the housing 15 by a movable portion 25a that rotates around an axis Ax1 (FIG. 2). Therefore, when the rotation mechanism 25 is operated and the movable portion 25a is turned, the skeleton member 12 and various components attached thereto are turned together with the housing 15 and the outer mirror 3 is folded.

  The camera 13 includes an end portion 28 on which a lens 27 directed toward the rear of the vehicle is disposed, and is fixed to the skeleton member 12 with a screw 29. In the visor portion 16, a through hole 30 is formed at a position facing the lens 27 and the end portion 28 in order to enable photographing with the camera 13. The through hole 30 penetrates the visor portion 16 from the inner side of the housing 15 toward the outer side behind the vehicle.

  The visor portion 16 is provided with a grommet 31 as an example of a hollow elastic member fitted in the through hole 30. The grommet 31 is made of synthetic rubber as an example of a flexible material. As the grommet material, other materials having flexibility such as elastomer can be selected. As shown in FIG. 4, the grommet 31 is connected to the hollow cylindrical portion 32 inserted into the through-hole 30, protrudes to the inner side of the housing 15, and is larger than the outer diameter of the cylindrical portion 32. An annular inner projecting portion 33 having a large outer diameter, and an outer diameter larger than the outer diameter of the tubular portion 32, which is connected to the cylindrical portion 32 on the opposite side of the inner projecting portion 33 and protrudes to the outside on the rear side of the vehicle. And an annular outer protrusion 34. Thereby, the grommet 31 covers the peripheral edge portion 30a of the through hole 30 so as to make a round while projecting to the inner side of the housing 15 and the outer side of the rear of the vehicle. The camera 13 is fixed to the skeleton member 12 in a state in which the lens 27 can receive light through the hollow portion 31 a of the grommet 31 and the end portion 28 where the lens 27 is disposed contacts the inner projecting portion 33 of the grommet 31. Yes. The grommet 31 is in an elastically deformed state when the end portion 28 of the camera 13 is pressed.

  The grommet 31 covers and closely contacts the peripheral edge 30a of the through hole 30 without a gap. The inner projecting portion 33, the cylindrical portion 32, and the outer projecting portion 34 are each smoothly connected. The inner projecting portion 33 gradually decreases in cross-sectional area toward the camera 13 in the direction of the center line CL of the through hole 30. The tip 33a of the inner protrusion 33 is rounded and makes a round in the circumferential direction, and contacts the end 28 of the camera 13 with a relatively small contact area. Since the inner projecting portion 33 of the grommet 31 is in contact with the end portion 28 of the camera 13 so that the distal end portion 33a makes a round in the circumferential direction, it is possible to prevent foreign matters such as raindrops and dust from entering the housing 15. The outer projecting portion 34 gradually decreases in cross-sectional area toward the side away from the camera 13 in the direction of the center line CL. Since the outer protrusion 34 is provided, even when raindrops adhering to the visor portion 16 flow downward in the vehicle, the outer protrusion 34 rectifies the raindrop so that it does not enter the hollow portion 31a and flows left and right. Therefore, it is possible to suppress the attachment of raindrops to the lens 27. As a result, it is difficult to affect the image captured by the camera 13.

  As shown in FIGS. 2, 3 </ b> A, and 3 </ b> C, power is supplied to the actuator 23, the rotation mechanism 25, and the camera 13 provided in the outer mirror 3, and the mirror side wire disposed in the housing 15 of the outer mirror 3. The harness 41 is performed by being connected to the vehicle body side wire harness 40 disposed inside the vehicle body 2 via the connector portion 42. The mirror-side wire harness 41 includes a first power supply line 41a for the rotation mechanism 25, a second power supply line 41b for the actuator 23, and a third power supply line 41c for the camera 13, and these power supply lines 41a to 41c are predetermined. It is configured by being appropriately bundled at places.

  Each of the power supply lines 41a to 41c is bundled up to a branch position (not shown) existing between the vehicle body side wire harness 40 and the rotation mechanism 25, and the second power supply line 41b and the third power supply line 41c are connected from the branch position. Branches in a bundled state. Then, the second and third feeders 41b and 41c in a bundled state are guided along the skeleton member 12 to the branch position Bp (see FIG. 3A) in front of the mirror support 11, and at the branch position Bp It branches into the 2 feeder line 41b and the 3rd feeder line 41c. One branched second power supply line 41 b is connected to the actuator 23 of the mirror support 11. The other branched third power supply line 41 c is arranged along the skeleton member 12 and led to and connected to the camera 13 in a state of being fixed by a clamp 44 provided on the skeleton member 12.

  Thus, the routing of the mirror-side wire harness 41 and the power supply lines 41a to 41c in the housing 15 is completed on the skeleton member 12, and the housing 15 is not involved in the routing. For this reason, even if an impact is applied to the housing 15, the impact is not directly input to the mirror-side wire harness 41, the connector portion 42, and the power supply lines 41a to 41c.

  According to the above embodiment, since the camera 13 is housed in the housing 15 of the outer mirror 3 and the lens 27 is located at the position of the through hole 30 formed in the visor portion 16, the installation area of the camera 13 is ensured. Therefore, it is not necessary to change the outer shape such as inflating the housing 13, and it is sufficient to adjust the shape of the mirror member 10 within the range of the visor portion 16 as shown in FIG. Thereby, compared with the form which changed the external shape, the air resistance during vehicle travel can be reduced. The camera 13 is attached to a skeleton member 12 that is a separate component from the housing 15 and the visor portion 16 of the outer mirror 3. For this reason, even when an impact is applied to the housing 15 and the visor portion 16 from the outside, the input of the impact to the camera 13 can be reduced, so that the orientation of the camera 13 is unlikely to change. Since a flexible grommet 31 is interposed between the end portion 28 where the lens 27 of the camera 13 is disposed and the visor portion 16, and the grommet 31 covers the peripheral edge portion 30 a of the through hole 30, the housing 15 Even if an impact is applied to the visor unit 16, the visor unit 16 can be prevented from damaging the lens 27 of the camera 13. In addition, it is possible to suppress entry of foreign matters such as raindrops from between the end portion 28 of the camera 13 and the visor portion 16 in a normal time when no external force is applied.

(Modification)
The grommet 31 fitted in the through hole 30 formed in the visor portion 16 having the above-described configuration is an example. For example, it can also be changed to a form using grommets 131 to 631 shown in FIGS. 5A to 5F.

  The basic structure of the grommet 131 shown in FIG. 5A is the same as that of the grommet 31, and includes the cylindrical portion 132, the inner protruding portion 133, and the outer protruding portion 134, and has the same effects as the grommet 31. The grommet 131 covers the peripheral edge portion 30 a of the through hole 30, but a cavity C is formed between the inner protruding portion 133 and the inner surface of the visor portion 16. The cavity C improves the flexibility of the inner protrusion 133 as compared with the same material and solid form. Thereby, even if an external force is applied to the housing 15 and the visor part 16 and the relative position between the visor part 16 and the end part 28 of the camera 13 changes, the followability to the change is enhanced. For this reason, even when the relative position of the grommet 131 changes, the contact between the end portion 28 and the grommet 131 is easily ensured, and the waterproof and dustproof properties are not easily broken by an external force.

  The basic configuration of the grommet 231 shown in FIG. 5B is the same as that of the grommet 31, and includes a cylindrical portion 232, an inner protruding portion 233, and an outer protruding portion 234, and has the same effects as the grommet 31. The inner projecting portion 233 includes a base portion 233a that is in contact with the inner surface of the visor portion 16, and a lip portion 233b that starts from the base portion 233a and extends away from the center line CL of the through hole 30. A groove G that makes a round is formed. For this reason, the softness | flexibility of the inner side protrusion part 233 increases by the groove | channel G, and the followability mentioned above improves. Therefore, even when the relative position between the visor portion 16 and the end portion 27 of the camera 13 changes, the grommet 231 can easily ensure contact between the end portion 27 and the grommet 231, and the waterproof and dustproof properties are not easily broken by external force.

  The basic configuration of the grommet 331 shown in FIG. 5C is the same as that of the grommet 31, and includes a cylindrical portion 332, an inner protruding portion 333, and an outer protruding portion 334, and exhibits the same operational effects as the grommet 31. The inner projecting portion 333 includes a base portion 333a that is in contact with the inner surface of the visor portion 16, and a lip portion 333b that extends from the base portion 333a in the direction away from the center line CL of the through-hole 30 and is turned back in the opposite direction at the turning point P. It is out. Since the lip portion 333b is configured to be folded back, the inner projecting portion 333 is formed so that the groove G1 facing the direction approaching the center line CL and the groove G2 facing the direction away from the center line CL are each made a round. . In addition, by providing a plurality of turning points P, it is possible to change so that two or more grooves are formed. In the grommet 331, the two grooves G1 and G2 are formed in the inner protruding portion 333, whereby the flexibility of the inner protruding portion 333 is increased and the followability described above is enhanced. For this reason, even when the relative position between the visor portion 16 and the end portion 28 of the camera 13 changes, the grommet 331 can easily ensure the contact between the end portion 28 and the grommet 331 and the waterproof and dustproof properties are not easily broken by external force. . Moreover, since the front-end | tip of the lip | rip part 333a has faced the direction approaching the centerline CL, compared with the form which has faced the direction away from the centerline CL, the inhibitory effect of a foreign material penetration | invasion is high.

  The basic structure of the grommet 431 shown in FIG. 5D is the same as that of the grommet 31, and includes a cylindrical part 432, an inner protruding part 433, and an outer protruding part 434, and has the same effects as the grommet 31. The inner projecting portion 433 includes a base portion 433a that is in contact with the inner surface of the visor portion 16, and a lip portion 433b that extends from the base portion 433a in a direction approaching the center line CL of the through hole 30. Since the tip of the lip portion 433b is oriented in a direction approaching the center line CL, the effect of suppressing the entry of foreign matter is higher than that in a configuration oriented in a direction away from the center line CL.

  The basic structure of the grommet 531 shown in FIG. 5E is the same as that of the grommet 31, and includes a cylindrical part 532, an inner protruding part 533, and an outer protruding part 534, and has the same effects as the grommet 31. The inner protruding portion 533 is configured in a bellows shape formed so that a plurality (two in the drawing) of grooves g1 and g2 arranged in the direction of the center line CL each go around. Thereby, the softness | flexibility of the inner side protrusion part 533 increases and the followability mentioned above increases. For this reason, the grommet 531 is easy to ensure contact between the end portion 28 and the grommet 531 even when the relative position between the visor portion 16 and the end portion 28 of the camera 13 is changed. . Note that the number of grooves formed in the inner protruding portion 533 may be changed as appropriate.

  The basic configuration of the grommet 631 shown in FIG. 5F is the same as that of the grommet 31, and includes a cylindrical portion 632, an inner protruding portion 633, and an outer protruding portion 634, and exhibits the same operational effects as the grommet 31. The inner projecting portion 633 has a base portion 633a in contact with the inner surface of the visor portion 16 and a plurality (three in the figure) of lip portions that are arranged concentrically with respect to the center line CL and extend away from the center line CL with the base portion 633a as a base point. 633b. Since each lip portion 633b arranged concentrically contacts the end portion 28 of the camera 13 in the grommet 631, even if the relative position between the visor portion 16 and the end portion 28 of the camera 13 changes as described above, all the lip portions It is difficult for the portion 633b to move away from the end portion 28 of the camera 13. Therefore, the grommet 631 has a high effect of suppressing foreign matter intrusion while ensuring the same flexibility as that of the form provided with a single lip portion.

  Although the said form applies an outer mirror to a vehicle as a door mirror, it can also be changed into the form applied to a vehicle as an outer mirror as a fender mirror. Moreover, it can change also to the form applied to the vehicle as an auxiliary | assistant mirror which is provided in the vehicle exterior and assists a door mirror etc.

  Aspects of the present invention derived from each of the above-described embodiments and modifications will be described below.

  An outer mirror of a vehicle according to an aspect of the present invention is an outer mirror of a vehicle that enables visual recognition at the rear of the vehicle, the mirror member having a mirror surface, and the mirror surface facing the rear of the vehicle. A mirror support that supports the mirror member from the back side of a mirror surface; a skeleton member to which the mirror support is attached and coupled to a vehicle body; and an objective unit that is directed toward the rear of the vehicle and includes a lens, A camera attached to a skeleton member; a housing covering each of the mirror support, the skeleton member, and the camera in a state where the mirror member is exposed; and the vehicle formed so as to surround the periphery of the mirror member. A visor unit coupled to the housing from a rear side, and the visor unit includes an inner side of the housing And a hollow elastic member that covers the periphery of the through hole so as to make a round and projects to the inner side and the outer side is provided. The camera is fixed to the skeleton member in a state in which the lens can receive light through the hollow portion of the elastic member and the objective portion is in contact with the elastic member. For example, in the above embodiment, a part of the camera 13 including the lens 27 and the end portion 28 corresponds to an example of an objective unit that is directed to the rear of the vehicle and includes the lens. In the said form and its modification, each of the grommet 31, 131-631 illustrated in FIG.4 and FIG.5A-FIG.5F is equivalent to an example of an elastic member.

  According to the outer mirror of this aspect, since the camera is accommodated in the housing and the lens is positioned at the position of the through hole formed in the visor portion, the housing is inflated to secure a camera installation area, etc. Therefore, it is sufficient to adjust the shape of the mirror member within the range of the visor part. As a result, the degree of change of the outer shape can be reduced. Further, the camera is attached to a skeleton member which is a separate component from the outer mirror housing and the visor. For this reason, even when an impact is applied to the housing or the visor portion from the outside, the input of the impact to the camera can be reduced. An elastic body is interposed between the objective part and the visor part of the camera, and the elastic body covers the peripheral edge of the through-hole, so that the visor part makes the lens of the camera even if an impact is applied to the housing or the visor part. Injury can be suppressed. Further, it is possible to suppress the intrusion of foreign matters such as raindrops from between the objective part and the visor part of the camera in a normal time when no external force is applied.
