Abstract

PURPOSE:To make the setting of parts achievable without any check to the impact absorption capacity of a horn pad, by setting the parts apart from the axis of a steering shaft via a fragile bracket attached tight to the setting boss of a steering wheel. CONSTITUTION:A setting boss 13 of a steering wheel 1 is fitted around the tip part 21 of a steering 2 shaft and clamped with a nut 22. At the upper part of the boss 13, a seat plate 14 is welded, while a setting bracket 3 being installed bent in an almost horizontal direction toward where a parts setting part 33 is out of an axis A of the steering shaft is installed tight to this seat plate 14. Then, a parts piece 4 is attached to the parts setting part 33 by the way of screwing a flange 41 projected through both sides of the setting part 33, by means of a screw bolt.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching components to the interior space of a steering wheel, and the present invention relates to a structure for attaching components to the interior space of a steering wheel.
A microcomputer circuit box can be attached to it.

In recent years, it has become necessary to install parts such as microcircuit boxes around the steering wheel in order to improve driving and power performance.

However, since this steering wheel is rotated by driving operations, the locations where parts can be attached are severely limited. For example, in a steering wheel (1) as shown in Fig. 1, a space is formed between the horn pad aυ and the back cover a, as shown in Fig. 2, so parts cannot be attached to this space. was considered.

However, if the parts are simply attached, when the horn pad αυ is bent due to an impact during an accident, it may interfere with the parts and fail to absorb the impact, which may impair safety.

The present invention has been made in consideration of such problems, and an object of the present invention is to provide a component mounting structure that allows components to be mounted without impeding the shock absorption ability of the horn pad aυ.

The gist of the present invention to achieve such an object is a structure for mounting components in the interior space of a steering wheel, in which a component is mounted at a position off the axis of the steering shaft.
The parts mounting structure is characterized in that the parts are mounted via a fragile mounting bracket fixed to a steering wheel mounting boss.

The present invention will be explained below based on illustrated embodiments.

Note that the same parts as in the conventional example are given the same reference numerals.

3 and 4 show an embodiment of the present invention.

As shown in Fig. 3, the tip t2υ of the steering shaft (2) is connected to the mounting boss (
It is inserted into 1″5 and fastened with a nut @.Boss α
A back cover α is fixed to the bottom of the horn pad αυ to form a space facing from below, and a seat plate αυ is welded and fixed to the upper part of the boss floor a. Spoke a that supports the handle ring at the corner of plate I and boss a3
The image is welded on.

Then, as shown in FIG.
The mounting platen (3) is fixed to the boss (13), and the mounting platen (3) is fixed to the boss (13), and the part mounting portion (to) is located approximately horizontally in a direction away from the axis of the steering shaft. Platinum) (3), Flanges O protruding from both sides of component (4) at the component attachment part (to) of (3)
υ and @υ are screwed together with screw bolts (6) and (6). The mounting bracket (3) has sufficient strength to support the component (4) in its normal state, but it easily deforms when an external force is applied to the component (4), and the mounting bracket (3) is not strong enough to support the component (4) in its normal state. It is weak by comparison.

If a human body collides with the horn pad aυ due to the impact of an accident, etc., and the horn pad aυ inverts from its normal position shown by the dashed line toward the back cover 02, as shown in Figure 5, parts may be damaged in the process. (4) interferes with the horn pad αυ. However, since the component (4) is supported by the fragile mounting bracket (3), when the component (4) is pushed by the horn pad aυ, the mounting bracket (3) bends or deforms and moves together with the horn pad Qυ. do. Therefore, even if the component (4) is a rigid body, it will not encounter strong resistance to the bending of the horn pad αυ, and the shock absorption ability of the horn pad aυ will not be impaired. Also, parts (4)
Since the part (4) is attached at a position off the axis (A) of the steering shaft (2), the movement of the part (4) is not hindered by contact with the tip of the steering shaft (2), and the mounting bracket ( With the deformation of 3), it easily moves within the space between the horn pad aυ and the back cover α2.

In addition, in the example, the mounting platen (3) T-crank shape was used to make it easily deformable, but other shapes that can be easily deformed may also be used. It is also possible to use a device that does not restrict the component (4).

According to the component mounting structure according to the present invention, the components can be attached to the interior space of the steering wheel without impeding the shock absorption ability of the horn pad, so the interior space can be effectively used as a component mounting space. Moreover, the shock absorbing ability of the horn pad is effectively maintained against shocks such as those caused by accidents, thereby ensuring safety.
