DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a vehicle motor for driving a sunroof, a power window, and the like, and more particularly to a mounting structure for a motor housed in a case and mounted on a vehicle body panel.

[0002]

2. Description of the Related Art A motor for driving a sunroof, a power window and the like is mounted inside a vehicle. For this reason, conventional techniques have been devised to reduce the generation of noise and vibration. For example, a sunroof motor to be used is housed in a case and uses a dedicated motor to prevent transmission of vibration and noise, and is fixed to the case by screwing. However, the use of a dedicated motor has a low degree of freedom in design and increases the cost.

[0003] Therefore, a motor that uses a general-purpose motor to reduce the cost is used. Using a general-purpose motor and soundproofing and anti-vibration measures, for example, wrap rubber around the motor and fix it by screwing the motor tap to the case or gluing the rubber with an adhesive. Was.

[0004]

However, in the above-mentioned conventional mounting method for a vehicle-mounted motor, in the fixing method of screwing the motor to the case, the vibration of the motor is transmitted to the case through the fixing portion, and the transmission of the vibration is performed. I can't prevent it.

[0005] In the case of fixing with an adhesive, a harmful gas to the motor is generated from the adhesive and corrodes the motor terminals or penetrates into the bearing portion to corrode the bearing.

Further, harmful gas is generated from the rubber for sound and vibration insulation wound around the motor, and the harmful gas causes corrosion of the terminals, and the rubber is deformed by the heat of the motor, and the motor support is loosened. May occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and a motor for a vehicle which can use a general-purpose motor to increase the degree of freedom of design and reduce the cost. An object of the present invention is to provide a mounting structure.

As the material of the support spring 6, rigid steel, alloy, plastic or the like can be used. The support spring 6 has a contact portion 61 that contacts the case surface of the motor 1 on one end side, and has a mounting portion 62 attached to the case housing 2 at the other end portion.

The contact portion 61 of the support spring 6 is
When the support spring 6 is attached to the motor 1, it is formed so as to be substantially parallel to the axis of the motor 1. With such a configuration, when the motor 1 is supported, the motor 1 can be stably supported in the circumferential direction. The contact portion 61 is connected to a mounting portion 62 via a connection portion 63.

The mounting portion 62 of the supporting spring has substantially the same shape as the mounting portion 52 of the leaf spring 5, and has a locking portion 64 at the lower end.
However, a pressing surface 65 is formed on the upper part. For more information,
The connecting portion 63 is bent so as to leave the locking portion 64 at the lower end and the pressing surface 65 at the upper portion. Then, the contact portion 61 of the support spring 6 is brought into contact with the peripheral surface on the other end (front) side of the motor 1, the mounting portion 62 is inserted into the support spring mounting portion 9 of the case housing 2, and the contact portion 61 is made to protrude. To maintain. By attaching the motor 1 to the case housing 2, the motor 1 is restrained from moving in the axial direction while being floated at one end by the leaf spring 5, and a force is applied by the support spring 6 at the other end. Will be supported. When a belt is hung on a pulley 10 provided on a drive shaft of the motor 1 and the belt is hung and connected to a pulley of a driven shaft, a radial pulling force acts on the drive shaft of the motor 1. I do. However, a force is applied by the support spring 6 against this force,
The motor 1 is maintained at a predetermined position.

The mounting portions 8 and 9 of the leaf spring 5 are provided on both sides of the case housing 2, respectively. The spring mounting part 8
And a support wall 23 provided at an interval outside the side wall 22 of the case housing 2. Further, the side wall 22
A mounting space is formed between the support wall 23 and the mounting portion 52 of the leaf spring 5 so that the mounting portion 52 can be fitted and mounted. A bottom is provided between these walls, and a slit 24 is provided in the side wall 22. . In addition, a partition wall 25 is provided to provide strength so that the side wall 22 and the support wall 23 are not excessively deformed.
Then, the mounting portion 52 of the leaf spring 5 fixed to the motor 1 is inserted between the side wall 22 and the supporting wall 23 of the spring mounting portion 8, the connecting portion 54 is passed between the slits 24, and the locking 55 is brought into contact with the bottom. The leaf spring 5 is attached to the case housing 2. Thereby, one end side (rear side) of the motor 1 is attached and supported in a floating state.

The support spring mounting portion 9 of the support spring 6 also includes
Except that it is not formed on both sides, the support wall 23, a bottom portion between the side wall 22 and the support wall 23,
It is composed of a slit 24 on the side wall 22 and the like. Then, the mounting portion 6 is formed so that the contact portion 61 of the support spring 6 projects.
2 is inserted into and attached to the support spring mounting portion 9.

The circuit board storage section 11 of the case housing 2 has
The control circuit components are mounted to control the motor 1. A driving mechanism including a mainspring spring, a clutch mechanism, a worm wheel member, a worm gear, a pulley, and the like is housed in the mainspring spring accommodating section 12, and the pulley is driven by a pulley-hung belt provided on a driving shaft of the motor 1, An urging force is applied to the mainspring via a worm wheel member.

A mainspring is accommodated in the large-diameter cylindrical portion of the worm wheel member, one end of which is fixed, and the other end on the center side is fixed to the shaft member. For example, when the worm wheel is rotated clockwise, the mainspring is gradually tightened and deformed to generate an urging force for rotating the worm wheel counterclockwise.

The procedure for mounting the vehicle motor of the present invention having the above configuration to the case is as follows.
1. A required member is housed in the mainspring spring accommodating portion 12, a belt is hung on a pulley, and the support spring 6 is mounted on the support spring mounting portion 9. Further, the fixing portion 51 of the leaf spring 5 is fixed to the motor 1 with a screw, the pulley 10 is hung on a belt,
Is attached to the spring mounting portion 8. Also, the motor 1 and the wiring of the board are connected appropriately. Thereafter, the lid 3 is screwed to the case housing 2 and assembled. Then, the case is fixed to a predetermined position of the vehicle body with a bolt.
