JP 2003-127773 A Japanese Patent No. 3620378 JP 2002-96684 A

  In the above-described conventional outer mirror of Patent Document 1, the housing cover can be easily attached to the housing body using the elastic locking piece. However, when the winker lamp portion described in the outer mirror of Patent Document 3 is provided for such an outer mirror of Patent Document 1, it is necessary to form a notch for installing the winker lamp portion in the housing cover. Therefore, it is difficult to obtain the mounting strength of the housing cover because the side portion of the housing cover is notched by the notch. Therefore, in order to obtain such mounting strength of the housing cover, it is also conceivable to employ a technique in which the elastic locking piece as described above is provided on the side portion of the housing cover and locked to the housing body. However, if it does so, it will be in the state where an elastic locking piece is located in the narrow space of a side part, and there exists a possibility that this may interfere with the mirror and other interior parts attached to the back part of a housing body. For this reason, there is a possibility that the layout of the interior parts is restricted. In addition, if this is done, the elastic locking pieces can easily be exposed from the outside through the gap between the mirror housing and the mirror. Therefore, when such a configuration is adopted, it is necessary to sacrifice aesthetics.

  Therefore, in order to increase the mounting strength of the housing cover, it is conceivable to provide an opening in a state in which the end portion of the side portion remains without providing a notch portion to the end portion of the side portion of the housing cover. However, in such a structure, since the notch portion is not provided to the end portion of the housing cover, when the housing cover is attached, the side portion of the housing cover interferes with the winker lamp portion, and the housing cover Another problem is that the cover cannot be successfully attached to the housing body. In particular, when the side portion of the blinker lamp portion is protruding, it is more difficult to attach the housing cover.

  By the way, when the mirror housing has a two-piece structure including a housing main body and a housing cover, wind noise may occur around the end of the housing cover depending on the connection structure between the housing main body and the housing cover. In this regard, the structure of the parting part described in the above-described outer mirror of Patent Document 2 can prevent wind noise when it is adopted at the protruding end (upper end) of the housing cover. If such a structure is adopted at the front part (front side) of the mirror housing where the traveling wind is likely to hit, the boundary between the housing body and the housing cover is located at the front part of the mirror housing. There is a risk that wind noise may be generated due to intrusion of traveling wind. For this reason, conventionally, such a parting structure is not adopted in the front part (front surface) of the mirror housing, and the lower edge part of the housing cover and the opposing surface of the housing body facing the same are both formed flat. At the expense of fixing the lower edge portion of the housing cover and the housing body, a method has been adopted in which the running wind that has entered the groove is smoothly flowed to prevent the generation of wind noise.

  However, when such a method is adopted, there is a difficulty in that the mounting strength of the housing cover cannot be increased.

The present invention has been made in view of such circumstances, and a first problem thereof is that, in an outer mirror provided with a blinker lamp portion, the housing cover can be easily attached to the housing body, and the housing cover An object of the present invention is to provide an outer mirror capable of increasing the mounting strength.
A second problem is to provide an outer mirror capable of preventing the generation of wind noise while ensuring the mounting strength of the housing cover.

  In order to achieve the first object, the outer mirror of the present invention has a housing main body in which a rear-viewing mirror is accommodated in a back portion, and a plurality of elastic locking pieces locked to the housing main body. An outer mirror including a mirror housing having a housing cover locked by the plurality of elastic locking pieces at a front portion of the housing body, the outer mirror being disposed between the housing body and the housing cover. A plurality of elastic locking pieces including a turn signal lamp portion having a curved horizontally long surface exposed along a curved horizontally elongated hole-shaped opening formed from the front portion of the cover to the vicinity of the end portion of the side portion; When the housing cover is turned in the direction of covering the housing body with the side of the housing cover aligned with the side of the housing body, At least a portion that can be locked to the housing main body and that corresponds to at least one of the plurality of elastic locking pieces on the side opposite to the side portion of the housing main body is attached to the housing main body. An inclined portion is formed that guides to a position where the elastic locking piece can be locked while being elastically deformed in a direction away from the side portion when the elastic locking piece is rotated in the covering direction.

  According to this outer mirror, since the opening of the housing cover is formed in a curved horizontally long hole formed from the front part of the housing cover to the vicinity of the end of the side part, the side part of the conventional housing cover is Higher mounting strength of the housing cover can be obtained compared to the case where the notch is notched to the end. Accordingly, it is not necessary to adopt an attachment mode such as providing an elastic locking piece for locking on the side portion of the housing cover, and an outer mirror having both high mounting strength and aesthetics can be obtained.

  The plurality of elastic locking pieces for locking the housing cover to the housing main body is rotated when the housing cover is rotated in the direction of covering the housing main body with the side of the housing cover aligned with the side of the housing main body. Since it can be locked to at least the housing main body, when attaching the housing cover to the housing main body, the side portions of the housing main body and the housing cover are aligned with each other, and the housing cover is moved to the housing main body around the side portion. This can be done by rotating in the covering direction. That is, the housing cover is covered with the housing body while being rotated along the longitudinal direction of the winker lamp portion (curved horizontally long shape), and the housing cover opening and the winker lamp portion are generated in the process of covering the housing cover. Can be engaged from a linear direction. Accordingly, the housing cover can be attached to the housing body while the curved laterally long surface of the blinker lamp portion is well exposed to the opening formed in the curved laterally elongated hole shape. Therefore, it is not necessary to cut out the opening portion to the side portion of the housing cover as in the prior art, and the problem that the side portion interferes with the winker lamp portion when the housing cover is attached can be solved. Thereby, the housing cover can be easily attached to the housing body, and the attachment strength of the housing cover can be increased.

  Further, since the opening is formed in a curved horizontally long hole formed from the front part of the housing cover to the vicinity of the end part of the side part, when attaching the housing cover to the housing body, the edge part of the opening part is formed. The housing cover can be rotated so as to be hooked on the end portion of the blinker lamp portion, so that the advantage of easy attachment can be obtained.

In addition, when the housing cover is rotated in a direction to cover the housing body, the elastic locking piece is located on the side corresponding to at least one of the plurality of elastic locking pieces on the side opposite to the side portion of the housing body. An inclined portion that guides to a position that can be locked while being elastically deformed away from the portion is formed, so that when the housing cover is attached to the housing body, the elastic locking piece can be smoothly moved to the position where the lock can be locked. As a result, the housing cover is easily attached.
Moreover, since the elastic locking piece is guided to a position where it can be locked while being elastically deformed in the direction away from the side portion by the inclined portion during mounting, the side portion of the housing cover faces the side portion of the housing body. Thus, a force in the pressing direction is applied, and it is possible to suitably prevent the side portion of the housing cover from being detached from the side portion of the housing body, thereby realizing a smooth attachment of the housing cover.

  In order to achieve the second problem, the outer mirror of the present invention has a housing main body in which a rear-viewing mirror is accommodated on the back and a plurality of elastic locking pieces locked to the housing main body. And a housing cover locked by the plurality of elastic locking pieces at a front portion of the housing body, wherein at least a part of a boundary portion between the housing body and the housing cover is a front portion of the housing body. An outer mirror including a mirror housing located at a position between the housing main body and the housing cover, and a curve formed from the front portion of the housing cover to the vicinity of the end portion of the side portion. A blinker lamp portion having a curved laterally long surface exposed along the laterally long hole-shaped opening, and the plurality of elastic locking pieces are arranged on the side of the housing body. When the housing cover is rotated in a direction in which the housing cover is fitted to the housing body, the housing can be locked to at least the housing body and at a position near the boundary. A movement restricting means for restricting the relative movement of the housing cover with respect to the housing main body without hindering the locking of the elastic locking piece due to the rotation of the housing cover is provided at an opposite portion between the main body and the housing cover. It is provided.

  Also in this outer mirror, since the opening of the housing cover has a curved horizontally long hole formed from the front part of the housing cover to the vicinity of the end of the side part, the side part of the conventional housing cover is notched. Higher mounting strength of the housing cover can be obtained compared to the case where the housing cover is cut out.

  Further, when attaching the housing cover to the housing body, the side portions of the housing body and the housing cover are aligned with each other, and the housing cover is rotated in a direction to cover the housing body around the side portion. Can do. That is, also in this outer mirror, the housing cover is covered with the housing body while being rotated along the longitudinal direction of the blinker lamp portion (curved horizontally long shape), and thus the housing cover is generated in the process of covering the housing cover. The opening portion of the turn signal lamp and the blinker lamp portion can be engaged from a linear direction, and thereby the housing is formed while the curved horizontally long surface of the turn signal lamp portion is well exposed to the opening formed in a curved horizontally elongated hole shape. A cover can be attached to the housing body. Therefore, it is possible to eliminate the problem that the side portion interferes with the winker lamp portion when the housing cover is attached without cutting out the opening portion to the side portion of the housing cover as in the prior art. Thereby, the housing cover can be easily attached to the housing body, and the attachment strength of the housing cover can be increased.

  Further, since the opening is formed in a curved horizontally long hole formed from the front part of the housing cover to the vicinity of the end of the side part, the edge of the opening is hooked on the edge of the blinker lamp part. Thus, the mounting method of rotating the housing cover can be adopted, and the advantage that the mounting is easy can be obtained.

  In addition, the relative movement of the housing cover with respect to the housing body is restricted at a position near the boundary portion between the housing body and the housing cover without disturbing the locking of the elastic locking pieces by the rotation of the housing cover. Since the movement restricting means is provided, good fixing between the lower edge portion of the housing cover and the housing body can be realized. Therefore, a structure in which the lower edge portion of the housing cover and the facing surface of the housing body facing the housing cover are both formed flat without using the conventional parting structure at the front portion of the mirror housing. Thus, an outer mirror that can prevent wind noise while securing the mounting strength of the housing cover can be obtained.

  Furthermore, the movement restricting means can be constituted by a concave portion and a convex portion that are engaged with each other, or can be constituted by an engaging projection piece that is engaged with each other. According to the outer mirror provided with such movement restricting means, the lower end portion of the housing cover can be easily and reliably fixed to the housing body at a position near the boundary portion.

  Further, the housing cover may be configured such that the vicinity of the end of the side portion is an undercut portion. According to such an outer mirror, the portion near the end portion of the side portion of the housing cover is an undercut portion, so that the portion near the end portion of the side portion becomes the end portion of the blinker lamp portion when the housing cover is attached. It becomes easy to catch, and smooth rotation of the housing cover can be realized. Therefore, it becomes easier to attach the housing cover.

Further, the blinker lamp portion may be configured such that a portion located on the side portion of the housing cover protrudes to the side of the housing cover through the opening.
According to such an outer mirror, the outer mirror excellent in visibility of the blinker can be obtained by the portion protruding to the side of the housing cover.
In addition, as described above, when the housing cover is attached, the opening of the housing cover and the blinker lamp portion can be engaged from a linear direction. Even in the structure provided in the winker lamp portion, the housing cover is smoothly attached without interfering (interfering) with the rotation when the housing cover is attached.

According to the present invention, in the outer mirror having a blinker lamp portion, an outer mirror can be obtained in which the housing cover can be easily attached to the housing body and the attachment strength of the housing cover can be increased.
In addition, according to the present invention, it is possible to obtain an outer mirror that can prevent the generation of wind noise while ensuring the mounting strength of the housing cover.

  Next, the procedure for assembling the outer mirror according to the present embodiment will be described with reference to FIGS. FIGS. 5A to 5C are partial cross-sectional views showing the state of the side part when the housing cover is put on, and FIGS. 6A and 6B show the state when the housing cover is put from the bottom side of the mirror housing. FIGS. 7A to 7C are explanatory views showing a state in which the elastic locking piece is guided by the inclined portion and locked in the hole portion.

  First, as shown in FIG. 5A, the blinker lamp portion 50 is fixed to a predetermined position near the side portion 21a of the housing body 20 by using a screw or the like (not shown). Thereafter, the side portion 31a of the housing cover 30 is brought close to the side portion 21a of the housing body 20, and the left edge portion 33 (the edge portion 33 of the side portion 21a) of the housing cover 30 is moved to the housing as shown in FIG. The main body 20 is hooked on the left side groove portion 23 of the side portion 21a (the groove portion 23 of the side portion 31a).

  Next, in this state, the housing cover 30 is rotated around the side portion 31a in a direction covering the housing body 20 (see FIG. 6A). At this time, as shown in FIG. 5B, the edge portion 52b of the lens portion 52 of the winker lamp portion 50 is brought into contact with the edge portion 37a of the end portion vicinity portion 31 of the housing cover 30 so as to be hooked. The rotation of 30 is performed smoothly. Further, when the lens portion 52 of the blinker lamp portion 50 is exposed to the opening portion 37 of the housing cover 30, they are engaged with each other, thereby guiding the rotation of the housing cover 30 (see FIG. 5C). ). Thereby, each elastic locking piece 32a-32h of the housing cover 30 is reliably locked by each hole 22a-22h of the housing main body 20 (refer FIG.6 (b) (only the elastic locking piece 32e is shown in the figure). )).

At this time, since the inclined portions 22D and 22E are provided at the edge portions of the holes 22d and 22e provided in the portion 21b opposite to the side portion 21a of the housing main body 20, the following assembly is performed. Is called. In addition, since the effect | action by inclination part 22D, 22E is the same, here, the effect | action in one inclination part 22E is demonstrated.
As shown in FIG. 7A, the housing cover 30 is rotated toward the housing body 20, the elastic locking piece 32e approaches the inclined portion 22E, and then the claw portion 32e as shown in FIG. 7B. When 'comes into contact with the inclined portion 22E, the elastic locking piece 32e is elastically deformed in the direction of the arrow A1 in the drawing, that is, away from the side portion 31a of the housing cover 30 (side portion 21a of the housing body 20). While descending, it goes down the inclined portion 22E. As a result, as shown in FIG. 6B, a force in the direction in which the side portion 31a of the housing cover 30 is pressed toward the side portion 21a of the housing body 20 (force in the direction of arrow A2 in the figure) acts. Thus, the side portion 31a of the housing cover 30 is preferably prevented from being detached from the side portion 21a of the housing body 20.
Thereafter, as shown in FIG. 7 (c), the claw portion 32e 'of the elastic locking piece 32e finishes descending the inclined portion 22E, and the elastic locking piece 32e is elastically restored in the direction of arrow B in the figure, and the hole portion 22e. It is locked to the edge of the.

  When the housing cover 30 is attached to the housing main body 20, the convex portion 36 of the housing cover 30 is inserted into and engaged with the concave portion 26 of the housing main body 20. Further, as shown in FIG. The projecting pieces 35 and 35 of the housing cover 30 are engaged with the 20 projecting pieces 25 and 25 (only one is shown in the drawing, the same applies hereinafter), and the lower portion of the housing cover 30 is fixed to the housing body 20. At this time, as shown in the figure, the lower edge portion 34 of the housing cover 30 is brought into close contact with the step portion 24 so as to enter the concave portion 24a formed between the projecting piece 25 of the housing body 20 and the step portion 24. However, since the projecting piece 35 comes into contact with the projecting piece 25 of the housing body 20 from below, the relative movement of the housing cover 30 with respect to the housing body 20 is suitably restricted.

  According to the outer mirror described above, the opening 37 of the housing cover 30 is formed in the shape of a curved horizontally elongated hole formed from the front part of the housing cover 30 to the end part vicinity 31 of the side part. Higher mounting strength of the housing cover 30 can be obtained compared to the case in which the side portion of the housing cover is notched to the end portion by the notch portion. Therefore, it is not necessary to adopt an attachment mode such as providing an elastic locking piece for locking on the side portion 31a of the housing cover 30, and an outer mirror having both high mounting strength and aesthetics can be obtained.

  The plurality of elastic locking pieces 32 a to 32 h for locking the housing cover 30 to the housing main body 20 are configured so that the side cover 21 is aligned with the side portion 21 a of the housing main body 20. Since it can be locked to at least the housing body 20 when it is rotated in the direction of covering the housing 20, the housing cover 30 is rotated in the direction of covering the housing body 20 around the side portion 31a. Installation can be performed. That is, the housing cover 30 is put on the housing main body 20 while being rotated along the longitudinal direction of the winker lamp portion 50, and the opening 37 and the winker lamp portion of the housing cover 30 generated in the process of covering the housing cover 30. 50 can be engaged from a linear direction. Thus, the housing cover 30 can be attached to the housing body 20 while the curved lateral surface of the lens portion 52 of the winker lamp unit 50 is well exposed to the opening 37 formed in the curved laterally long hole shape. Therefore, it is not necessary to cut out the opening portion to the side portion of the housing cover as in the conventional case, and when the housing cover 30 is attached, the end portion vicinity portion 31 of the side portion 31a interferes with the lens portion 52 of the blinker lamp portion 50. The problem of hitting can be resolved. Thereby, the housing cover 30 can be easily attached to the housing body 20, and the attachment strength of the housing cover 30 can be increased. Further, since the engagement between the opening 37 of the housing cover 30 and the lens portion 52 of the blinker lamp portion 50 can be performed in a linear direction, the protruding portion 52a provided on the lens portion 52 causes the housing cover 30 to be engaged. Smooth attachment of the housing cover 30 is realized without interfering with (interfering with) rotation during attachment.

  Further, since the opening 37 is formed in a curved horizontally long hole formed from the front portion of the housing cover 30 to the end portion vicinity 31 of the side portion, when the housing cover 30 is attached to the housing body 20, the opening portion 37 is opened. The housing cover 30 can be rotated so that the edge portion 37a of the portion 37 is hooked on the end portion 52b of the lens portion 52 of the winker lamp portion 50, so that an advantage that attachment is easy can be obtained.

Further, in the portion 21b opposite to the side portion 21a of the housing main body 20, when the housing cover 30 is rotated in a direction to cover the housing main body 20, the elastic locking pieces 32d and 32e are moved away from the side portion 21a. Since the inclined portions 22D and 22E are formed so as to be guided to the lockable positions while being elastically deformed, the elastic lock pieces 32d and 32e can be locked when the housing cover 30 is attached to the housing body 20. It will be smoothly guided to the position, and the housing cover 30 can be easily attached.
In addition, the elastic locking pieces 32d and 32e are guided to a position where they can be locked while being elastically deformed in the direction away from the side portion 21a (31a) by the inclined portions 22D and 22E at the time of mounting. The side portion 31a of the housing cover 30 is preferably prevented from being detached from the portion 21a, and the housing cover 30 can be smoothly attached.

  Further, at the position near the boundary K, the housing main body 20 and the housing cover 30 are opposed to the housing main body 20 without obstructing the locking of the elastic locking pieces 32a to 32h by the rotation of the housing cover 30. Since the movement restricting means (the convex portion 36 and the concave portion 26, the protruding piece 25 and the protruding piece 35) for restricting the relative movement of the cover 30 is provided, the lower edge portion 34 of the housing cover 30 and the housing main body 20 are Good fixing can be performed easily and reliably. Accordingly, without adopting the conventional parting structure at the front part of the mirror housing H, the lower edge part 34 of the housing cover 30 and the opposing surface (step part 24) of the housing body 20 facing this are both provided. A flat structure can be adopted, and an outer mirror that can prevent wind noise while securing the mounting strength of the housing cover 30 can be obtained.

  Further, by forming the end portion vicinity portion 31 of the side portion 31a of the housing cover 30 to be an undercut portion, when the housing cover 30 is attached, the end portion vicinity portion 31 of the side portion 31a becomes the turn signal lamp portion 50. It becomes easy to catch on the edge part 52b of this lens part 52, and the smooth rotation of the housing cover 30 is realizable. Therefore, it becomes easier to attach the housing cover 30.

As mentioned above, although embodiment which concerns on this invention was described, it is also possible to change these further variously and to use.
For example, the formation position and the number of elastic locking pieces can be set as appropriate. The movement restricting means may be any means that restricts the relative movement of the housing cover 30 with respect to the housing body 20 without hindering the locking of the elastic locking pieces 32a to 32h due to the rotation of the housing cover 30. The shape can be arbitrary.

Further, as shown in FIG. 8, a housing portion 28 for housing the base portion 51 of the winker lamp portion 50 is provided at the front portion of the housing body 20, and the base portion 51 of the winker lamp portion 50 is provided with respect to this housing portion 28. And may be fixed using screws 54. By setting it as such a structure, the blinker lamp part 50 can be positioned uniformly and the outer mirror which is easy to assemble is obtained. In this case, the shape of the base portion 51 was reduced so as to be easily accommodated in the accommodating portion 28.
Moreover, although the outer mirror which concerns on above-described embodiment was an electric retractable type, it is not limited to this, A manual retractable type or a fixed type may be sufficient.

It is an external appearance perspective view which shows the outer mirror which concerns on one Embodiment of this invention. It is a disassembled perspective view of the mirror housing which comprises an outer mirror similarly. It is the expansion | deployment perspective view for demonstrating the latching structure of a housing main body and a housing cover similarly. (A) is a partial expanded sectional view which shows the connection structure in the parting part of a mirror housing, (b) is the partial expanded sectional view which shows the connection structure of a boundary part. (A)-(c) is the fragmentary sectional view which showed the mode of the side part at the time of covering a housing cover. (A) (b) is the figure which looked at the mode at the time of covering a housing cover from the bottom face side of the mirror housing. (A)-(c) is explanatory drawing which showed a mode that an elastic locking piece was guided to the inclination part and latched by the hole. It is an expanded sectional view which shows the modification of fixation of a blinker lamp part.
