Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vibration isolation device for a disc player mounted on a vehicle.

[0002]

[Prior Art]

 Conventionally, there has been a technique of mounting a pickup chassis on a chassis base via a vibration-proof rubber damper with four-point support.

[0003]

[Problems to be solved by the device]

 The prior art is disadvantageous in terms of assembly work because the pickup chassis is attached to the state where four vibration-proof rubber dampers are attached to the integrated chassis base.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is a side chassis in which the side wall of the chassis base to which the front and rear anti-vibration rubber dampers are attached is removable.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, (1) is a chassis base of a disc player mounted on a vehicle, (2) is a pickup chassis arranged on the lower surface side of the chassis base (1), and vibration-proof rubber dampers are provided at four corners of the chassis base (1). (3) is attached via a damper holder (4) which will be described later, while the damper pins (5) are fixed by protruding from the four corners of the pick-up chassis (2) to the left and right outside, and the anti-vibration rubber damper (3) is attached. The damper pin (5) is inserted from the inside into the pin hole (6) of (1), and the pickup chassis (2) is attached to the chassis base (1) via a vibration-damping rubber damper (3) at four points.

The pickup chassis (2) has a disc drive mechanism including a turntable for placing a disc and a drive motor for rotating the disc, a laser pickup for reading recorded information on the disc, and a laser pickup for diametrical direction of the disc. A pickup mechanism including a pickup motor that moves the disk, a chucking mechanism including a chuck plate that fixes the disc to the turntable, and a chuck arm that supports the chuck plate so that the disc can be moved toward and away from the turntable are attached.

Reference numerals (7) and (8) in the figure denote left and right side walls of the chassis base (1), and the right side wall (8) is integrally formed by bending the chassis base (1) while the chassis base (1) is formed. On the opposite side of the right side wall (8), a side chassis (9) that is detachably attached is provided, and the side chassis (9) forms a detachable left side wall (7) on the chassis base (1). A right holder mounting surface (10) extending from the front and rear ends of the right side wall (8) along the front and rear edges of the chassis base (1) is integrally formed on the right end side of (1), while the left side of the side chassis (9) is formed. The left holder mounting surface (11) extending from the front and rear ends of the wall (8) along the front and rear edges of the chassis base (1) is integrally formed, and the front and rear antivibration rubber damper (3) on the right side is attached to the chassis base (1). ) Side, The left and right anti-vibration rubber damper (3) is attached to the side chassis (9) side.

Therefore, when mounting the pickup chassis (2) to the chassis base (1), with the side chassis (9) removed, the front and rear damper pins (5) on the right side of the pickup chassis (2) are attached to the right side of the chassis base (1). Of the front and rear anti-vibration rubber damper (3), and then the pin hole (6) of the front and rear anti-vibration rubber damper (3) on the side chassis (9) side on the left side of the pickup chassis (2). This is done by fitting the front and rear damper pins (5) and fixing the side chassis (9) to the chassis base (1), and the four vibration damping rubber dampers (3) are attached to the chassis base (1). Compared to mounting the pickup chassis (2) on the current state, the movement of the damper pin (5) in the insertion direction is not restricted with respect to the pin hole (6), so mounting is possible. The work can be done easily and the anti-vibration rubber damper (3) will not be damaged.

Further, (12) in the figure is a front chassis that is detachably attached to the front side of the chassis base (1), and both sides of the front chassis are attached to the left and right holder attachment surfaces (11) (10). Be done. (13) is a rear chassis that can be detachably attached to the rear side of the chassis base (1), and both sides of the rear chassis are attached to the left and right holder attaching surfaces (11) and (10).

The side chassis (9), the front chassis (12) and the rear chassis (13) are fixed to the chassis base (1) with screws.

As shown in FIGS. 2 to 4, the anti-vibration rubber damper (3) has ribs (15) integrally formed on both outer circumferences of a damper body (14) having a circular cross section, and a chassis base (1). ), The pin hole (6) is provided from the center of the end face of the damper body (14) to the middle part of the damper body (14).

Further, the damper holder (4) is a synthetic resin molded product, and includes a C-shaped holder body (16) which is detachably fitted to the outer periphery of the damper body (14) between the left and right ribs (15), and The holder base (16) is composed of a rectangular holder base (18) forming a vertical groove (17) on its side surface and a rib (19) for fixing the rear surface of the holder body (16) to the front surface of the holder base (18). Attach to the mounting surface (10) (11), project the holder main body (16) inside the holder mounting surface (10) (11), and fit the anti-vibration rubber damper (3) into the holder main body (16) from this opening. It is something to wear.

Furthermore, the holder mounting surface (10) (11) is provided with a groove or a groove (20) having a lower edge or an upper edge partially recessed to form the holder mounting surface (10). A square hole (21) surrounding the holder base (18) is formed at a position corresponding to the groove (20) at a joint portion of the front chassis (12) and the rear chassis (13) with respect to (11), and a holder mounting surface ( 10) A pressing surface (22) which is joined to the lower edge or the upper edge of (11) and closes the open end of the groove (20) is integrally formed on the front chassis (12) and the rear chassis (13).

Therefore, the damper holder (4) is attached to the holder mounting surface (10) (11) with the vertical groove (of the holder base (18) (with the front chassis (12) and the rear chassis (13) removed). 17) is inserted into the groove (20) of the holder mounting surface (10) (11) from below or above, and then the front chassis (12) and the rear chassis (13) are mounted, so that the pressing surface (22) Since the open end of the groove (20) is closed and the holder base (18) is pressed into the groove (20), the damper holder (4) does not use screws on the holder mounting surfaces (10) and (11). It can be fixed, that is, the anti-vibration rubber damper (3) can be attached to the chassis (1) (9) without using screws, and the damper holder (4) can be attached to the holder mounting surface. (10) Compared with using and fixing screws to (11), that is, using screws for fixing and fixing the vibration damping rubber damper (3), the installation work can be done easily, and Screws are no longer needed and costs can be reduced.

After mounting and fixing the damper holder (4), the holes (21) of the front chassis (12) and the rear chassis (13) are formed on the rear surface of the holder base (18) protruding outward from the holder mounting surfaces (10) and (11). ) Are matched, the joint surfaces of the front chassis (12) and the rear chassis (13) can be brought into close contact with the holder mounting surface (10) (11).
