[Technical field]

[0001] The present invention relates to a vehicle door mirror, and in particular to an improvement in which a plate-shaped rectangular parallelepiped antenna is attached to the outer surface of a housing main body having a mirror accommodating recess in which a mirror is accommodated, and the outer surface of the housing main body is covered with a cover. [Background technology]

[0002] Such a vehicle door mirror is already known, as disclosed in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6097996 Summary of the Invention [Problem to be solved by the invention]

[0004] In the antenna disclosed in the above-mentioned Patent Document 1, one of the plate surfaces of the antenna is oriented toward the outer surface of the housing body. (The surface with the largest area) The housing body is held in a facing position (hereinafter referred to as flat placement) by a pair of opposing elastic engaging claws protruding from the outer surface of the housing body.

[0005] However, due to the layout of the various parts arranged on the outer surface of the housing body, The rectangular parallelepiped antenna is placed with its plate surface facing the outer surface of the housing body. Lift up In such a case, if the above-mentioned flat antenna holding structure is adopted, a pair of opposing elastic engaging claws would have to be arranged close to each other to engage with the narrow side edge of the antenna, which may result in poor assembly and stability in the housing. In addition, it is not easy to mold a pair of elastic engaging claws arranged close to each other in this way.

[0006] The present invention has been made in view of such circumstances, and a plate-shaped rectangular parallelepiped antenna is placed upright, that is, the plate surface of the antenna is upright with respect to the outer surface of the housing body. Lift up It is an object of the present invention to provide a vehicle door mirror that can be easily assembled to a housing body in a stable state and can be held in a stable state, and moreover, the holding portion can be easily formed.

Means for Solving the Problems

[0007] In order to achieve the above object, in the present invention, a plate-shaped rectangular parallelepiped antenna is attached to the outer surface of a housing body having a mirror housing recess for housing a mirror in a posture in which the plate surfaces of the front and back two surfaces, which are the surfaces having the largest area, are raised with respect to the outer surface of the housing body, and the outer surface of the housing body is covered with a cover. A vehicle door mirror, comprising: a support wall having a flat surface for supporting one of the plate surfaces of the antenna; and an elastic engagement claw extending in a row on the other plate surface side of the antenna and engaging with the antenna, which are erected on the outer surface of the housing body. This is the first feature. Flat Further, in the present invention, in addition to the first feature, the elastic engagement claw is provided with a claw portion having a first inclined surface descending from a ridge line to the side opposite to the housing body and a second inclined surface descending from the same ridge line to the housing body side at a tip portion. This is the second feature.

[0008] Furthermore, in the present invention, in addition to the first or second feature, an engagement wall with which one end portion in the longitudinal direction of the antenna engages is formed on the outer surface of the housing body. This is the third feature.

[0009] Furthermore, in the present invention, in addition to the third feature, a contact wall with which the other end portion in the longitudinal direction of the antenna contacts is formed on the outer surface of the housing body. This is the fourth feature.

[0010]

[0011] ​Furthermore, the present invention has a fifth feature in that, in addition to any of the first to fourth features, a side turn lamp is attached to the outer surface of the housing main body, and a molding core hole for the elastic engaging claw is provided in the housing main body so as to open between the support wall and the elastic engaging claw. Effect of the Invention

[0012] According to the first feature of the present invention, the outer surface of the housing body is provided with a support wall having a flat surface for supporting one plate surface of the antenna, and a flat surface of the support wall on the other plate surface side of the antenna. Flat Since the antenna is formed with elastic engagement claws that extend in a row and engage with the antenna, the antenna can be easily set in an upright position (standing position) with the plate surface, which is the surface with the largest area relative to the outer surface of the housing body, raised, in the engagement position with the elastic engagement claws, i.e., the mounting position, by sliding the antenna between the support wall and the elastic engagement claws, and therefore the antenna in a standing position can be easily assembled. Moreover, the shape of the support wall is simple, and it is sufficient that the engagement claws are only those that face the plate surface on one side of the antenna, so that they can be easily formed.

[0013] According to a second feature of the present invention, the guiding action of the first sloping surface of the claw portion of the elastic engaging claw allows the antenna to easily slide between the support wall and the elastic engaging claw, contributing to improved ease of assembly of the antenna, and after assembly, the pressing action of the second sloping surface of the claw portion of the elastic engaging claw urges the antenna toward the housing main body while pressing it against the wide wall surface of the support wall, allowing the antenna to be maintained in a stably held position without any rattling for a long period of time.

[0014] According to the third feature of the present invention, the antenna can be easily and reliably assembled in a fixed position by sliding the antenna between the support wall and the elastic engaging claw while positioning one longitudinal end of the antenna with the engaging wall, thereby improving the ease of assembly and retention of the antenna.

[0015] According to the fourth feature of the present invention, in addition to engaging one longitudinal end of the antenna with the engaging wall, by bringing the other end into contact with the abutting wall, play in the longitudinal direction of the antenna can be reliably prevented, and a more stable holding state of the antenna can be obtained.

[0016] According to the fifth feature of the present invention, the core hole for forming the elastic engaging claw provided in the housing body so as to open between the supporting wall and the elastic engaging claw formed close to each other is set to a narrow width substantially equal to the plate thickness of the antenna. Therefore, when the side turn lamp disposed on the outer surface side of the housing body is lit, light leakage from the core hole to the mirror housing recess side can be suppressed as much as possible.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0019] First, in FIGS. 1 and 2, a mirror housing 11 of a door mirror 10 that is supported to be storable in a side door of an automobile is composed of a housing body 14 made of synthetic resin having a mirror housing recess 13 in which a mirror 12 is accommodated, a lower cover 15 that covers the lower part of the housing body 14, and an upper cover 16 made of synthetic resin that covers the housing body 14 from the front direction on the side opposite to the mirror housing recess 13 separately from the lower cover 15. The housing body 14, the lower cover 15, and the upper cover 16 are detachably coupled by a snap-fit structure.

[0020] At the opening of the housing body 14, that is, at the opening end of the mirror housing recess 13, a mirror 12 for visually observing the rear side of the vehicle and a mirror holder 17 made of synthetic resin for holding the mirror 12 are arranged.

[0021] Referring also to FIG. 3, an electric storage unit 18 is attached to a base member 19 attached to the side door, and a drive part of the electric storage unit 18 is connected to the outer surface of the housing body 14 through a notch 23 of the lower cover 15. By the operation of the electric storage unit 18, it is configured to rotate between an upright position protruding laterally from the side door and a storage position stored on the side door side.

[0022] An electric mirror actuator 20 capable of adjusting the angle of the mirror holder 17 is attached to the outer surface of the housing body 14. The electric mirror actuator 20 is provided with a spherical support part 20a extending to the housing body 14 side and a pair of spherical drive parts 20b. The spherical support part 20a is connected to the mirror holder 17 through a first opening 26a of the housing body 14, and the pair of spherical drive parts 20b are connected to the mirror holder 17 through a pair of second openings 26b of the housing body 14, respectively.

[0023] On the outer surface of the housing body 14, a side turn signal lamp 21 is attached by a fixing member such as an engaging claw or a screw, and notches 23 and 24 that define a slit facing the light emitting portion 21a of the side turn signal lamp 21 are provided at the opposing edges of the lower cover 15 and the upper cover 16.

[0024] Referring to FIGS. 4 to 7, an antenna 27 for transmitting and receiving radio waves for a keyless entry system is attached to the outer surface of the housing body 14 covered by the lower cover 15 and the upper cover 16.

[0025] This antenna 27 It is the surface with the largest area has a plate-shaped rectangular parallelepiped shape with plate surfaces 27a and 27b on the front and back sides, and is attached to the housing body 14 in a posture where the plate surfaces 27a and 27b stand substantially perpendicular to the outer surface of the housing body 14 while aligning its longitudinal direction along the outer surface of the housing body 14. For its attachment, on the outer surface of the housing body 14, a support wall 28 and a pair of elastic engaging claws 29 that face the support wall 28 with a space slightly larger than the plate thickness of the antenna 27 are integrally erected.

[0026] The support wall 28 Flat slidably supports one plate surface 27a of the antenna 27 on the inner surface facing the elastic engaging claw 29. A guide wall 28a that protrudes higher than the elastic engaging claw 29 is continuously provided at a part of the support wall 28, at its central part in the illustrated example.

[0027] Also, a step portion 30 that connects to the outer surface at the middle portion in the height direction of the support wall 28 is formed on the housing body 14, thereby strengthening the support rigidity of the support wall 28 with respect to the antenna 27.

[0028] On the other hand, the flat inner surface of the support wall 28 FlatAt the tip of each of the elastic engagement claws 29 extending in a row, a claw portion 29a protruding toward the support wall 28 is provided. The claw portion 29a has a first inclined surface 32 that descends from the ridge line 31 to the side opposite to the housing body 14 and a second inclined surface 33 that descends from the ridge line 31 to the side of the housing body 14. The elastic engagement claw 29 is provided with elasticity so that the second inclined surface 33 elastically presses the corner portion 27c of the antenna 27 on the other plate surface 27b side of the antenna 27 whose one plate surface 27a is supported by the support wall 28. In the free state of the elastic engagement claw 29, the distance between the claw portion 29a and the support wall 28 is set smaller than the plate thickness of the antenna 27. Therefore, the elastic engagement claw 29 biases the antenna 27 supported by the support wall 28 toward the support wall 28 and the housing body 14 elastically by the claw portion 29a. A reinforcing rib 35 is formed on the back surface of each elastic engagement claw 29.

[0029] Further, in the housing body 14, a core hole 36 for forming the elastic engagement claw 29 is provided so as to open between the support wall 28 and the elastic engagement claw 29.

[0030] Furthermore, on the outer surface of the housing body 14, an engagement wall 37 having a U-shaped recess 37a with which one end portion in the longitudinal direction of the antenna 27 engages and a contact wall 38 with which the other end portion in the longitudinal direction of the antenna 27 abuts are integrally formed.

[0031] Next, the operation of this embodiment will be described.

[0032] When attaching the antenna 27 to the outer surface of the housing body 14, the antenna 27 is pushed between the support wall 28 and the elastic engagement claw 29 along the guide wall 28a (the pushing direction is indicated by the white arrow in FIG. 4). In this case, first, the front end portion 27f in the pushing direction of the antenna 27 presses the first inclined surface 32 of the claw portion 29a of the elastic engagement claw 29, deflects the elastic engagement claw 29, and widens the distance between the claw portion 29a and the support wall 28. When the antenna 27 is further pushed in this state, while sliding one plate surface 27a of the antenna 27 on the inner surface of the support wall 28, the antenna 27 can be slid between the support wall 28 and the elastic engagement claw 29. Flat The antenna 27 can be slid between the support wall 28 and the elastic engagement claw 29 while sliding one plate surface 27a of the antenna 27 on the inner surface of the support wall 28.

[0033] Then, when one longitudinal end of the antenna 27 engages with the recess 37a of the engagement wall 37 and the other longitudinal end thereof abuts against the abutment wall 38, the second inclined surface 33 of the claw portion 29a of the elastic engagement claw 29 resiliently contacts the corner portion 27c on the other plate surface 27b side of the antenna 27. As a result, the elastic engagement claw 29 is resiliently biased toward the support wall 28 and the housing body 14 by its elastic force.

[0034] Thus, the vertically standing antenna 27, i.e., the antenna 27 with the plate surfaces 27a and 27b arranged in a posture parallel to the outer surface of the housing body 14b, can be easily set at a predetermined mounting position between the support wall 28 and the elastic engagement claw 29, and the assemblability of the antenna 27 is improved. Rise up Moreover, due to the elastic biasing force of the elastic engagement claw 29, the antenna 27 is pressed against the wide wall surface of the support wall 28 while being biased toward the housing body 14 side, so that the antenna 27 can be maintained in a stable holding state without play for a long time.

[0035] In addition, not only is the shape of the support wall 28 simple, but the elastic engagement claw 29 only needs to face one plate surface 27b of the antenna 27, so that they are easy to form.

[0036] Furthermore, since the engagement wall 37 positions one longitudinal end of the antenna 27 by the recess 37a, the antenna 27 can be easily and surely assembled at a fixed position.

[0037] In addition, by engaging one longitudinal end of the antenna 27 with the engagement wall 37 and abutting the other longitudinal end thereof against the abutment wall 38, the play in the longitudinal direction of the antenna 27 can be surely prevented, and a more stable holding state of the antenna 27 can be obtained.

[0038] Moreover, in addition to engaging one longitudinal end of the antenna 27 with the engagement wall 37, by abutting the other longitudinal end thereof against the abutment wall 38, the play in the longitudinal direction of the antenna 27 can be surely prevented, and a more stable holding state of the antenna 27 can be obtained.

[0039] In addition, the core hole 36 for forming the elastic engagement claw provided in the housing body 14 so as to open between the support wall 28 and the elastic engagement claw 29 is set to a narrow width substantially equal to the plate thickness of the antenna 27. Therefore, when the side turn lamp 21 is lit, light leakage from the core hole 36 toward the mirror housing recess 13 can be suppressed as much as possible.

[0040] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the present invention described in the claims.
