Description

[Detailed Description of the Invention] Technical Field The present invention relates to a mounting structure for in-vehicle equipment such as a radio receiver or a magnetic tape playback device.

BACKGROUND ART Conventionally, when installing in-vehicle equipment such as a radio receiver or magnetic tape playback device to the instrument panel, in Japan, the main body of the device is attached to the vehicle body through the back of the mounting hole formed in the instrument panel using screws or the like. There are two mainstream methods: fixing the device in place, and installing the device by inserting it through a mounting hole formed in the instrument panel.In contrast, overseas, the latter method is preferred because it is easier to install. has become the mainstream. In the former method, the instrument panel and the front panel of the vehicle-mounted equipment can be mounted with a relatively small difference in level.

FIG. 5 is a sectional view showing the mounting structure of the latter method. The in-vehicle device 1 is housed in a mounting tube 4 fixed to a mounting hole 3 formed in an instrument panel 2 .
The front plate 5 of this in-vehicle device 1 is formed to protrude from the device body 6 in a step-like manner.

Mounting pieces 7 and 8 are fixed to both sides of the device body 6 with screws or the like. On the other hand, elastic pieces 11 and 12 are fixed to both side walls of the mounting tube 4. In the elastic pieces 11 and 12, locking claws 14 and 15 are formed on the upstream side in the insertion direction 13 of the in-vehicle device 1, and these locking claws 14 and 15 are formed on the mounting pieces 7 and 8. into the locking holes 16 and 17,
In this way, the vehicle equipment 1 is attached to the instrument panel 2 with the front plate 5 protruding from the attachment hole 3.
A frame 18 is attached around the front plate 5 to improve aesthetics.

In such a mounting structure, the size of the device main body 6 and the size of the mounting hole 3, that is, the size of the mounting tube 4, are relatively flexible, and therefore there are limitations depending on the vehicle type to which the in-vehicle device 1 is installed. Because there are few, it is highly versatile.

Problems to be Solved by the Invention In the prior art shown in FIG. 5, the elastic pieces 11 and 12 are
Base parts 11a and 12a fixed to the side wall of the mounting tube 4
A flexible portion 11 extending upstream from the insertion direction 13
b, 12b need to be long, so the amount of protrusion of the front plate 5 from the surface of the instrument panel 2 is, for example, 16
It was large, about mm, and was not aesthetically pleasing. In order to solve this problem, when the elastic pieces 11 and 12 are provided at the rear of the mounting tube 4, a space is provided in the device body 6 for the locking claws 14 and 15 of the elastic pieces 11 and 12 to fit into. This is not desirable from the standpoint of space saving. However, once these problems are solved, only this type of mounting structure will become mainstream in Japan, and
It is possible to standardize parts between domestic and overseas products, which is expected to reduce costs.

An object of the present invention is to provide a mounting structure for in-vehicle equipment that is highly versatile and has an improved aesthetic appearance.

Means for Solving the Problems In the present invention, a front plate whose width is narrower than the width of the device main body is provided to protrude from the device main body in a stepped manner, and the step is formed by the device main body and the front plate. The structure is for mounting an in-vehicle device on an instrument panel, the mounting tube having a locking hole and being inserted into the mounting hole from the front and fixed, and an end portion of the in-vehicle device. a mounting piece having a locking claw protruding outward and having an elastic piece that can be angularly displaced within a plane perpendicular to the insertion direction; The in-vehicle device is fixed to the side wall of the device main body along the stepped portion, and the in-vehicle device is inserted from the front of the mounting tube so that the locking claw of the elastic piece faces the locking hole, In this state, the locking pawl and the locking hole are engaged with each other.This is a mounting structure for a vehicle-mounted device.

Effect According to the present invention, on-vehicle equipment is housed in a mounting tube fixed to a mounting hole formed in an instrument panel.
A mounting piece including an elastic piece is fixed to the side wall of the device body, and a locking pawl is formed at the end of the elastic piece. This locking pawl can be angularly displaced within a plane perpendicular to the direction in which the in-vehicle equipment is inserted into the mounting tube, and a locking hole is formed in the side wall of the mounting tube corresponding to this locking pawl. Therefore, by inserting the in-vehicle device from the front of the mounting tube, the locking claw of the elastic piece fits into the locking hole within the gap between the mounting hole and the front plate, Vehicle-mounted equipment is mounted with its front plate protruding from the mounting hole of the instrument panel.

Embodiment FIG. 1 is a cross-sectional view showing a mounting structure for an in-vehicle device 21 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing the mounting procedure.
