Description

  The present invention relates to a vehicle door mirror disposed on a side portion of an automobile, for example, and particularly belongs to the technical field of an electric retractable door mirror that can be stored by a motor.

  Conventionally, a door mirror disposed on a side of an automobile has a mirror base fixed to the vehicle body side and a mirror housing that holds the mirror, and the mirror housing is housed inside the mirror housing. An electric storage unit for switching between a state and a use state is incorporated (see, for example, Patent Document 1).

  The electric storage unit includes a motor, a control board for controlling the motor, and the like. In the control board of Patent Document 1, a connection terminal to the motor is provided so as to protrude from the board surface. On the other hand, the motor has a terminal insertion hole into which the connection terminal of the control board is inserted.

And the edge part of the control board is being fixed in the state fitted to the fitting groove provided in the inner surface of the case which accommodates a motor and a control board.

JP 2005-186668 A

  By the way, when the connection terminal which protrudes from a control board is provided like patent document 1, the space | interval of a connection terminal may be fluctuate | varied by causes, such as a manufacturing error. On the other hand, since the terminal insertion holes of the motor are provided in a motor case that hardly allows deformation, the distance between the terminal insertion holes is maintained at a substantially constant interval. Therefore, when the connection terminal of the control board is inserted into the terminal insertion hole, the interval between the connection terminals may be different from the interval between the terminal insertion holes. In this case, an external force is applied to the control board from the connection terminal in a state where the connection terminal is inserted, and there is a possibility that the circuit element is damaged or a solder portion is cracked.

  Furthermore, in the case of a vehicle door mirror, it is necessary to prevent the connection terminal from coming out of the terminal insertion hole due to vibration of the vehicle body. As a countermeasure against this, in Patent Document 1, the edge of the control board is provided in the fitting groove of the case. It is fitted. However, in such a case, a force in the opposite direction acts on the portion of the control board where the connection terminal is provided and the edge of the control board pressed by the fitting groove of the case so that it does not come off. As a result, a bending force is generated on the control board, which may cause damage to the circuit elements and cracks in the solder portion.

  The present invention has been made in view of such points, and an object of the present invention is to prevent damage to circuit elements and cracks in the solder portion in advance by preventing excessive force from being generated on the control board. .

  In order to achieve the above object, in the present invention, the motor side connection terminal is provided so as to protrude from the motor, and the motor side connection terminal is inserted into the control board from the direction intersecting the protrusion direction and sandwiched between the board side connection A terminal is provided, and the motor holder prevents the connected control board from moving in the protruding direction of the motor side connection terminal.

The first invention is
A mirror base fixed to the vehicle body,
A mirror housing for holding the mirror;
In the vehicle electric retractable door mirror including an electric storage unit for rotating the mirror housing with respect to the mirror base to switch between the storage state and the use state,
The electric storage unit includes a motor that generates a rotational force of the mirror housing, a control board having a circuit element that controls the motor, and a motor holder that holds the motor.
The motor is provided with a motor-side connection terminal protruding,

The motor holder is provided with a board movement restraining portion for restraining the control board in a connected state from moving to the front end side in the protruding direction of the motor side connection terminal.

  According to this configuration, when connecting the control board and the motor, the control board is moved in a direction crossing the protruding direction of the motor side connection terminal, whereby the motor side connection terminal is moved to the board side connection terminal. Is inserted and pinched. Since the control board in the connected state is restrained from moving in the protruding direction of the motor side connection terminal by the board movement restraining portion of the motor holder, the motor side connection terminal does not come out of the board side connection terminal. Therefore, by holding the motor-side connection terminal between the board-side connection terminals and preventing the control board from moving in the protruding direction of the motor-side connection terminal, the motor-side connection can be made even if body vibrations occur. It is possible to maintain the connection state between the terminal and the board side connection terminal.

  In the connected state, the motor-side connection terminal protrudes from the motor, so that the motor-side connection terminal itself can be deformed by external force compared to the case where it is inserted into the terminal insertion hole formed in the motor case as in the past. Therefore, even if the distance between the motor side connection terminals and the distance between the board side connection terminals is slightly deviated, an excessive force is hardly generated on the control board due to the deformation of both terminals.

  Furthermore, since the insertion direction when the motor side connection terminal is connected to the board side connection terminal and the direction in which the board movement suppression unit suppresses the movement of the control board are crossed, a bending force is applied to the control board. Is less likely to occur.

According to a second invention, in the first invention,
The board movement suppressing unit of the motor holder guides the control board in a direction in which the motor side connection terminal is inserted into the board side connection terminal.

  According to this configuration, when the motor side connection terminal is connected to the board side connection terminal, the control board is guided by the board movement suppressing portion of the motor holder, so that the connection workability is improved.

  According to this configuration, when the control board is arranged above the motor and connected to the motor, the board movement suppressing unit can suppress the control board from moving upward, so that the vehicle body vibrates in the vertical direction. In this case, it is possible to prevent the motor side connection terminal from being detached from the board side connection terminal.

According to a fourth invention, in the second invention,
The board movement suppression part of the motor holder has a groove into which the edge of the control board is inserted, and the width of the groove is set longer than the thickness dimension of the edge of the control board. Features.

  According to this configuration, it is possible to suppress the control board from moving to the front end side in the protruding direction of the motor side connection terminal by inserting the edge of the control board into the groove of the motor holder. At this time, since the width of the groove is longer than the thickness dimension of the edge of the control board, if there is a manufacturing error in each part, the control board can move in the width direction of the groove to allow the manufacturing error. This makes it difficult for an excessive force to act on the control board.

  According to the first invention, the motor side connection terminal is provided so as to protrude from the motor, and the control board is provided with the board side connection terminal for inserting and clamping the motor side connection terminal from the direction intersecting the protruding direction, Since the motor holder prevents the control board in the connected state from moving in the protruding direction of the motor side connection terminal, the connection between the motor side connection terminal and the board side connection terminal is possible even if vehicle body vibration occurs. The state can be maintained, and an excessive force is hardly generated on the control board, so that breakage of the circuit element and cracking of the solder portion can be prevented in advance.

  According to the second invention, the control board can be guided by the board movement restraining portion of the motor holder, so that the connection workability of the motor side connection terminal can be improved.

  According to the third invention, in the case of the layout in which the control board is arranged above the motor, the connection state between the motor side connection terminal and the board side connection terminal is maintained even if vertical vibrations occur in the vehicle body. Can do.

  According to the fourth invention, since the width of the groove of the substrate movement suppressing portion of the motor holder is made longer than the thickness dimension of the edge portion of the control substrate, it is possible to allow a manufacturing error occurring in each portion. As a result, it is possible to make it difficult to generate an excessive force on the control board.

Since the second motor side connection terminal 20d is sandwiched between the side plate portions 51a and 51a of the second board side connection terminal 51, the control board 21 does not move in the left-right direction. Further, the front edge portion 21b and the rear edge portion 21c of the control substrate 21 are inserted into the groove 45d of the front substrate guide portion 45 and the groove 46d of the rear substrate guide portion 46, and the upper protrusion 45c moves upward. 46c prevents the first and second motor side connection terminals 20c and 20d from coming out of the first and second board side connection terminals 50 and 51.

  The motor holder 22 to which the control board 21 is attached is accommodated in the casing 23. When the control board 21 is about to move to the right, a contact portion (not shown) provided on the inner surface of the casing 23 comes into contact with the control board 21 from the right side to move the control board 21. Can be prevented.

  As described above, according to this embodiment, when the control board 21 is connected to the motor 20, the first and second motor side connection terminals 20 c and 20 d protrude from the motor 20. The first and second motor side connection terminals 20c and 20d themselves have a structure that allows deformation due to an external force as compared with a case where the first and second motor side connection terminals 20c and 20d are inserted into terminal insertion holes formed in the motor case. Even if the distance between 20c and 20d and the distance between the first and second board side connection terminals 50 and 51 are slightly deviated from each other, an excessive force is applied to the control board 21 due to the deformation of both terminals 20c, 20d, 50 and 51. Is less likely to occur.

  Furthermore, the insertion direction when connecting the first and second motor side connection terminals 20c, 20d to the first and second board side connection terminals 50, 51 and the holding of the control board 21 by the upper protrusions 45c, 46c. Therefore, it is difficult for the control board 21 to generate a bending force. Therefore, it is possible to prevent damage to the circuit elements of the control board 21 and cracks in the solder portion.

  Further, since the control board 21 can be guided by the front board guide part 45 and the rear board guide part 46 of the motor holder 22 at the time of connection, the connection workability of the first and second motor side connection terminals 20c and 20d can be improved. Can be good.

  The above-described embodiment is merely an example in all respects and should not be interpreted in a limited manner. Further, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

  As described above, the electric retractable door mirror for a vehicle according to the present invention can be disposed, for example, on a side portion of an automobile.
