Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a retractable headlamp for a vehicle, and more particularly to a mounting structure for an electric motor for driving the lamp.

(Prior Art) Conventionally, a retractable headlamp has been used as an automobile headlamp. This retractable headlamp, that is, a retractable headlamp is, for example, disclosed in Japanese Utility Model Laid-Open No. 63-95944, is housed in a storage compartment when the headlamp is not in use, and is stored outside when the headlamp is used. It is designed to project and light up. An electric motor and a link mechanism are used to move such a retractable headlamp between a storage position and a use position and to open and close the cover of the headlamp storage chamber in conjunction with the retractable headlamp. Further, in an emergency such as when the motor fails, an operation knob capable of manually rotating the motor is provided on the motor main body so as to be able to be manually moved.

By the way, since the emergency operation knob is preferably arranged in the engine room from the viewpoint of operability, the drive motor and the link mechanism are usually also provided in the engine room. However, the volume of the engine room tends to shrink more and more due to the short nose and low bonnet due to the design requirements for the front body of an automobile, while the engine performance is getting higher and higher. Since the volume occupied by the main body and its accessories tends to increase, it has become difficult to accommodate the headlamp driving motor and the link mechanism in the engine room.

Therefore, there is a motor provided inside the bumper so that the operation knob can be operated from the opening of the bumper or the lower side of the bumper. However, when the motor is provided at such a position, the operability of the operation knob is reduced. Not only bad, but water,
There is a concern that mud or the like may enter and road surface interference, and the distance between the headlamp and the motor becomes long, which complicates the link mechanism.

(Purpose of Invention) In view of the above-mentioned circumstances, the present invention is for driving a retractable headlamp that has good operability of the operation knob and that can satisfy the design requirements of a front vehicle body with a short nose and a low bonnet. An object is to provide a motor mounting structure.

(Construction of the Invention) In the present invention, the motor for driving the retractable lamp is arranged under the wheel apron, and the emergency operation knob is
It is characterized by penetrating the wheel apron and protruding into the engine room.

(Effect of the Invention) According to the present invention, since the headlamp driving motor is arranged below the wheel apron, it suffices if there is a space in the engine room where the operation knob can be operated. The space can be reduced and the front nose and short bonnet can be easily made. In addition, the emergency operation knob can be operated from the inside of the engine room, improving operability. Further, there is an advantage that the distance between the motor and the headlamp becomes short and the structure of the link mechanism becomes simple.

(Examples) Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

1 to 3, a front bumper 1 and a front fender 2 forming a side surface of the vehicle body are provided at a front end portion of the vehicle body.
Is provided. The front bumper 1 is attached to a front end of a front frame 5 extending in the vehicle front-rear direction along a side portion of the engine room 4 together with a cross member 6, and the side end portion is bent rearward of the vehicle body to form a third portion.
As shown in the figure, it extends along the lower edge of the front fender 2. A wheel apron 7 forming a front wheel tire house 3 extends in parallel to the inside of the vehicle body at the side end portions of the front fender 2 and the front bumper 1. The lower side of the wheel apron 7 extends horizontally toward the inside of the vehicle body to form a horizontal wall portion 7a, and the inner end of the horizontal wall portion 7a is bent downward and joined to the upper edge of the front frame 5. There is. The front frame 5 has a closed cross section 10 formed by the front frame outer 8 and the front frame inner 9, and a front end of the front frame outer 8 is formed with an extension 8a extending downward to form a side end of the cross member 6. It is joined.

Below the horizontal wall portion 7a of the wheel apron 7, there is provided a reinforcement 11 for mounting a retractable headlamp driving motor 13 described later.
As is apparent from FIG. 3, the reinforcement 11 is a first horizontal wall 11a parallel to the horizontal wall 7a of the wheel apron 7, and is bent downward from the inner end of the horizontal wall 11a. Vertical wall portion 11b and this vertical wall portion 1
Second horizontal wall portion 11 bent inward from the lower end of 1b
c, the outer end of the first horizontal wall portion 11a is bent upward and joined to the wheel apron 7, and
The inner end of the horizontal wall portion 11c is joined to the extension portion 8a of the front frame outer. In addition, in FIG.
Indicated by marks are spot welding points. In addition, the structure is facilitated by the drawing so that there is a slight gap between each member at the joint.

Reference numeral 12 is a retractable headlamp, and 13 is an electric motor for driving the retractable headlamp 12. The motor 13 has a main body 1 as shown in FIG.
4 and a tubular portion 15 fixed to the main body portion 14, and an emergency operation knob 16 is provided at the tip of the tubular portion 15. A base end of an arm 18 is fixed to an output shaft 17 protruding outward from the main body 14 of the motor 13, and a link mechanism 19 is attached between the tip of the arm 18 and the retractable headlamp 12. . The link mechanism 19 includes an upper plate 20 that can rotate about a fulcrum A.
A lower plate 21 rotatable about the fulcrum B, a rod 22 connecting the plates 21 and 21, and a rod 23 connecting the lower plate 21 and the tip of the arm 18. The upper plate 20 is fixed to the retractable headlamp 12, and when the arm 18 fixed to the output shaft 17 of the motor 13 rotates and its tip takes the uppermost position (point C in FIG. 4), Each member of the link mechanism 19 moves to the position indicated by the one-dot chain line (the reference numeral of each member is shown with a dash) to move the retractable headlamp 12 to the use position 12 '. Further, when the tip of the arm 18 reaches the lowest position (point D in FIG. 4), the retractable headlamp 12 is configured to move to the retracted position 12 ″. When the headlamp 12 cannot be driven by the motor 13, the headlamp 12 can be moved as described above by rotating the operation knob 16.

The body portion 14 of the motor 13 is attached to the vertical wall portion 11b of the reinforcement 11 below the horizontal wall portion 7a of the wheel apron 7, and the tubular portion 15 of the motor 13 is attached to the horizontal wall portion of the reinforcement 11. The operation knob 16 provided at the tip of the cylindrical portion 15 extends upward through the hole 25 formed in the portion 11a and the window 26 formed in the horizontal wall portion 7a of the wheel apron 7 and is provided in the engine room 4. It is protruding. In addition, the link mechanism 19 is also the window 2
It is connected to the headlamp 12 through 6. A tank 27 of the power steering device is disposed behind the window 26, and the operation knob 16 projects into the space between the tank 27 and the headlamp 12 to facilitate the manual operation of the operation knob 16. .

As is clear from the above description, in the present embodiment, the main body portion 14 of the drive motor 13 of the retractable headlamp 12 is arranged below the horizontal wall portion 7a of the wheel apron 7, and the operation knob 16 thereof is set to the wheel. Since the window 26 opened in the horizontal wall portion 7a of the apron 7 is penetrated and protruded into the engine room 4, the operability of the operation knob 16 is good, and the motor main body portion 14 is attached to the engine room 4.
Since no space is required when it is provided inside, it is easy to make the vehicle body short nose and low bonnet.
Further, since the distance between the motor main body 14 and the retractable headlamp 12 becomes short, there is an advantage that the structure of the link mechanism 19 is simplified.
