Abstract

PURPOSE:To make it possible to detect kinetic acceleration in an arbitrary direction with respect to the position of a detector, by supporting the wt. positioned at the central part of a conductive outer container by a conductive spring and filling the space between the outer container and the wt. with a pressure- sensitive substance. CONSTITUTION:A wt. having a conductive surface is positioned at the center of an outer cubic metal container 1 having conductivity and conductive springs 4 (4a-4d) are stretched spacially at equal angles from the center of said container 1. Further, an insulating substance 5 electrically insulates the conductive springs 4 and the metal container 1 and the space between the metal container 1 and the conductive wt3 is filled with pressure-sensitive rubber 2. When force is added from a surface C to a surface A, electric resistance between terminal 6c and the conductive outer container 1 is changed most largely. When force is added from the intermediate between a surface B and the surface C, the electric resistance between the terminal 6c and the outer container 1 and that between the terminal 66 and the container 1 are changed to the same degree. Therefore, the magnitude and direction of acceleration applied to the outer container 1 can be known by the electrical signal generated at the terminal.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detector that detects the magnitude and direction of acceleration in any direction with respect to the position of the detector.

An object of the present invention is to provide a device that can detect motion acceleration in any direction with respect to the position of a detector.

According to the present invention, an electrically conductive outer container, a weight disposed at the center of the interior thereof and having a conductive surface, and the outer container are electrically insulated and are spaced at equal spatial angles from the center of the weight. An acceleration detector is obtained comprising a plurality of electrically conductive springs that extend at a pressure of at least 1,000, and a filler that is sensitive to pressure between an outer container and a weight.

Next, the present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

In FIG. 1, one embodiment of the present invention includes a cubic conductive outer container 1, a weight 3 having a conductive surface located in the center of the conductive outer container, and a conductive weight placed in the center. ,
and a conductive spring 4 that serves as an electrical conduction path, an insulator 5 that electrically insulates the conductive spring and the metal container, a terminal 6 that takes out the electrical signal of the conductive spring, and a terminal 6 that connects the metal container and the metal container to the outside. It has a pressure sensitive rubber 2 filled between it and the conductive weight.

A weight that has a quantity tries to conserve its motion, so when a force is applied to the outer container, the weight held in the center seems to remain stationary, so it generates a force in the opposite direction of the force. and compress the pressure-sensitive material. Then, a change in electrical resistance occurs in the compressed portion of the pressure-sensitive material.

For example, in FIG. 1 (al), when a force is applied from the 0 plane to the A plane, the electrical resistance between the terminal 6C and the conductive outer container changes the most compared to other terminals. 8 again
When a force P is applied between the surface and the zero surface, the electrical resistance between the terminal 6b and the outer container and the electrical resistance between the terminal 6C and the outer container change to the same extent.

Therefore, if the direction of the outer container is determined in advance, the magnitude and direction of the acceleration applied to the outer container can be known from the electrical signal generated at the terminal.

As explained above, the present invention supports the weight located at the center of the conductive outer container with a plurality of four or more electrically conductive springs that extend at equal angles in space, and connects the outer container and the weight. By filling the gap with a pressure-sensitive substance, it is possible to detect the magnitude and direction of arbitrary motion acceleration with respect to the position of the metal container.
