Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle remote control outside mirror.

[0002]

[Prior art]

 Generally, as shown in FIGS. 6 and 7, this type of outside mirror includes a stay 10 fixed to a vehicle body, a mirror 12 fixed to a mirror holder 11, an actuator housing 14 and a mirror housing fixed to a holder frame 13. 15 is provided. The mirror holder 11 is attached to an actuator housing 14 via a ball joint 16 so as to be vertically and horizontally swingable. The actuator housing 14 has two motors built therein and has two ball joints 17 and 18 that move forward and backward depending on each motor. One of the ball joints 17 connects the actuator housing 14 and the upper part of the mirror holder 11, and the other ball joint 18 connects the actuator housing 14 and the left side of the mirror holder 11.

Since the conventional outside mirror has such a structure, when one motor built in the actuator housing 14 is driven to move the ball joint 17 forward and backward, the mirror 12 moves vertically with the ball joint 16 as a fulcrum. It swings, and the vertical tilt angle of the mirror 12 can be adjusted by this. When the other motor is driven to move the ball joint 18 forward and backward, the tilt angle of the mirror 12 in the left-right direction can be adjusted.

[0004]

[Problems to be solved by the device]

 In the conventional outside mirror described above, the mirror 12 is swingably supported by the actuator housing 14 by the ball joint 16 in order to adjust the tilt angle of the mirror 12 in the vertical and horizontal directions. Even if the motor is used, if the dimensional difference is allowed in the fitting portion of the ball joint 16 so that the mirror 12 operates smoothly, the mirror 12 vibrates due to wind pressure when the vehicle is running.

In view of the above problems, it is an object of the present invention to provide an outside mirror in which a mirror operates smoothly even with a motor having a small output and which can prevent vibration due to wind pressure during traveling.

[0006]

[Means for Solving the Problems]

 The present invention provides a mirror mounted on a stay via a universal joint so that the tilt angle in the vertical direction and the tilt angle in the horizontal direction can be adjusted, and the tilt angle in the up and down direction of the mirror fixed to the stay can be adjusted. In a remote control type outside mirror having one actuator and a second actuator fixed to the stay and adjusting a tilt angle of the mirror in the left-right direction, the remote control type outside mirror is rotatably assembled to the stay around the universal joint. A lock member that removably engages with an engaging portion integrally provided on the mirror to prevent the mirror from swinging in the vertical and horizontal directions, and a third actuator that rotates the lock member are provided. Characterize.

[0007]

[Operation and effect of the device]

 According to the present invention, when the first actuator or the second actuator is driven in a state in which the engagement portion integrally provided on the lock member and the mirror is disengaged, the mirror swings about the universal joint as a fulcrum, The vertical or horizontal tilt angle is adjusted. On the other hand, if the lock member is rotated by the third actuator to engage with the engaging portion, the swinging of the mirror around the universal joint is prevented. For this reason, even if there is allowance for the allowable dimensional difference in the fitting portion of the ball joint so that the mirror operates smoothly even if the outputs of the first and second actuators are small, the vibration of the mirror due to the wind pressure during traveling will not occur. It can be surely prevented.

【Example】

 The present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a remote-controlled outside mirror according to an embodiment of the present invention. The outside mirror is provided with a stay 20 fixed to the vehicle body, a mirror housing 21, and a mirror 22 mounted so as to cover the front surface of the mirror housing 21, and the mirror housing 21 is screwed to a base plate 23 fixed to the tip of the stay 20 with screws 24. It is stuck in.

A holder frame 26 is fixed to the base plate 23 with screws 25. As shown in FIG. 3, the holder frame 26 has a substantially hexagonal box shape, and four protruding pieces 26a are erected on the bottom surface, and an actuator housing 27 is fitted between the protruding pieces 26a. A ball joint 28 is provided at the center of the bottom surface of the actuator housing 27, and the ball joint 28 is fitted into a socket 29a provided on the back surface of a mirror holder plate 29 to which the mirror 22 is fixed. The mirror 22 is attached to the actuator housing 27 by the ball joint 28 and the socket 29a so that the tilt angle can be adjusted vertically and horizontally.

As shown in detail in FIG. 3, two ball joints 30 and 31 are attached to the bottom surface of the actuator housing 27 such that the ball joints 30 and 31 can move forward and backward, and the actuator housing 27 moves the ball joints 30 and 31 forward and backward. Two motors are built in for driving. The ball joint 30 is fitted in a socket 29b provided above the socket 29a of the mirror holder plate 29, and the ball joint 31 is fitted in a socket 29c provided on the left side of the socket 29a. Thus, the tilt angle of the vertical direction of the mirror 22 can be remotely adjusted by moving the ball joint 30 forward and backward by the first motor built in the actuator housing 27, and by moving the ball joint 31 forward and backward by the second motor. The tilt angle of 22 in the left-right direction can be adjusted remotely.

A third motor 32 is fixed to the base plate 23. The output shaft 32a of the third motor 32 is arranged concentrically with the ball joint 28, and the lock lever 33 is fixed to the output shaft 32a. Both ends of the lock lever 33 are projected to the outside of the holder frame 26 through slits 26a formed on both side surfaces of the holder frame 26 facing each other, and pins 34 are projectingly provided at respective projecting end portions. The slit 26a has a required length so that the lock lever 33 can rotate about the output shaft 32a of the third motor 32 as a fulcrum.

On the other hand, a pair of arcuate protrusions 35 are fixed to the mirror holder plate 29 at symmetrical positions with respect to the socket 29a. Since each projection 35 has a required radius of curvature, when the lock lever 33 is rotated by the third motor 32 to the lock position shown by the solid line in FIG. The pressure contact engagement is performed, whereby the vertical and horizontal swinging of the mirror 22 about the ball joint 28 is prevented. On the other hand, when the lock lever 33 is rotated to the unlock position shown by the chain double-dashed line in FIG. 3, the engagement between the pin 34 and the projecting piece 35 is released, which causes the mirror 22 to move up and down with the ball joint 28 as a fulcrum. It is possible to swing to the left and right.

FIG. 5 shows an example of an electric circuit for controlling the operation of the first motor and the second motor built in the third motor 32 and the actuator housing 27. One terminal of the third motor 32 is connected to the fixed contact a on the lock side of the select switch 37 via the relay switch 36, and the other terminal of the third motor 32 is turned off via the relay switch 38. It is connected to the fixed contact b on the lock side, and the movable contact piece of the select switch 37 is connected to the power source B. The coil 36a of the relay switch 36 is grounded via the limit switch 39, and the coil 38a of the relay switch 38 is grounded via the limit switch 40. Both limit switches 39 and 40 are arranged to be opened and closed by a lock lever 33. The limit switch 39 is closed when the lock lever 33 is in the lock position shown by the solid line in FIG. 3, and is opened only when it reaches the unlock position shown by the chain double-dashed line in FIG. Further, the limit switch 40 is closed when it is in the unlock position shown by the chain double-dashed line, and is opened only when it reaches the lock position.

One terminal of the first motor 41 for adjusting the vertical tilt angle of the mirror 22 is connected to the movable contact piece of the switch 42, and the other terminal is connected to the movable contact piece of the switch 43. . One terminal of the second motor 44 for adjusting the left and right tilt angles of the mirror 22 is connected to the movable contact piece of the switch 45, and the other terminal is connected to the movable contact piece of the switch 46. The movable contact pieces of the switches 42, 43, 45 and 46 are always connected to the fixed contact point a side, and are switched and connected to the fixed contact point b side only during manual operation. The a-side fixed contact of each switch 42, 43, 45, 46 is grounded, and the b-side fixed contact is connected to the unlock side fixed contact a of the select switch 37 via the delay timer 47.

Since the electric circuit has the above configuration, when the select switch 37 is switched to the unlock side fixed contact a, the coil 36a is excited and the relay switch 36 is switched from the fixed contact a side to the b side. One terminal of the motor 32 is connected to the power source B. As a result, the third motor 32 rotates in the forward direction and the lock lever 33 rotates counterclockwise from the lock position shown by the solid line in FIG. When the lock lever 33 reaches the unlock position shown by the chain double-dashed line in FIG. 3, the limit switch 39 opens and the third motor 32 stops and the limit switch 40 closes. When the lock lever 33 is in the unlock position, the pin 34 is disengaged from the projecting piece 35, so that the mirror 22 can swing up and down and left and right with the ball joint 28 as a fulcrum.

When the select switch 37 is switched to the unlock side and the switch 42 is switched to the fixed contact b side after a predetermined time set by the delay timer 47, one terminal of the first motor 41 is switched to the power source B. When connected, the motor 41 rotates normally. As a result, the ball joint 30 advances and the mirror 22 tilts forward. On the other hand, when the switch 43 is switched to the fixed contact b side, the other terminal of the first motor 41 is connected to the power source B and the motor 41 rotates in the reverse direction so that the ball joint 30 moves backward and the mirror 22 moves backward. Incline. Similarly, when the switch 45 is switched to the fixed contact b side, the second motor 44 rotates forward and the ball joint 31 advances, so that the mirror 22 tilts to the right. When the switch 46 is operated, the mirror 22 tilts to the left.

After the switches 42, 43, 45, 46 are selectively operated to adjust the vertical and horizontal tilt angles of the mirror 22, the select switch 37 is switched to the lock side, so that the limit switch 40 is closed. The coil 38a is excited, and the other terminal of the third motor 32 is connected to the power supply B. As a result, the third motor 32 rotates in the reverse direction, and the lock lever 33 rotates clockwise from the unlocked position shown by the chain double-dashed line in FIG. When the lock lever 33 reaches the lock position, the limit switch 40 opens, so that the third motor 32 stops and the limit switch 39 closes. In this state, the pin 34 press-contacts with the projection 35, so that vertical and horizontal swinging of the mirror 22 about the ball joint 28 is prevented.

As described above, according to this embodiment, the mirror 22 can be releasably locked by the pressure contact engagement of the pin 34 provided on the lock lever 33 and the protrusion 35 provided on the mirror holder 29. For this reason, even if the allowable dimensional difference in the fitting portion of the ball joint 28 is allowed to allow the mirror 22 to operate smoothly even if the outputs of the first and second motors 41 and 44 are small, it is not Vibration of the mirror 22 can be reliably prevented.
