共振の問題点が解消される特徴を有している。 In other words, vehicles that move at high speed, such as automobiles, are constantly accelerated or decelerated due to uneven road surfaces or braking when starting or stopping. does not work,
It is necessary to detect only the shocks that occur during a collision when the detection device truly needs to be activated, and to activate it reliably in the event of an accident that only occurs in these cases.
Conventionally, this type of detection device has a weight attached to the tip of a piano wire (Japanese Patent Publication No. 10098/1973).
or one using a coil spring (Jikko 48-
28196 Publication) are known, but since these use piano wire or coil spring wire, the operation becomes sensitive due to the spring constant of the wire and can be used in cases other than collision accidents. There was a drawback of activating the safety device. In particular, conventional devices using a vibration system have the drawback of resonating with vibrations caused by the engine and the movement of the vehicle, and there are many problems in the design and installation method of the device. For this reason, two permanent magnets are placed at an appropriate distance inside a non-magnetic housing, and a magnetic floater is installed between these permanent magnets (Jikkosho).
48-13857) has been proposed. This detection device uses the attractive force of a magnet, and the lower limit of the operating shock is defined by the magnetic force and the weight of the floating magnetic material.
Compared to the actuating body using the above-mentioned wire rod, this actuator has the feature that the problem of resonance in the vibration system is solved.

を生じたり、又はねかえりにより誤作動を生じる
問題点があつた。Problems to be Solved by the Invention However, such conventional safety devices have a problem in that when the floating body is activated by impact, it causes chattering due to its inertia, or malfunctions due to sagging.

衝撃検知装置を提供することを目的としている。 Therefore, the present invention was proposed in order to solve the malfunction caused by inertia-induced chattering and bouncing in detection devices for floating magnetic bodies that use such magnetic force. The purpose is to provide a detection device.
問題点を解決するための手段

のである。Means for solving the problem Namely, a housing having a space inside and made of a non-magnetic material, magnets having different polarities, and movably disposed at predetermined positions in the internal space of the housing, It also includes a floating magnet that is magnetized to the same polarity as one of the magnets, and an electrical contact that is controlled by this floating magnet, and when there is no impact, the floating magnet is held at a predetermined position in the internal space of the casing by the magnetic force of the magnet. At the same time, the floating magnet moves from a predetermined position to control the electrical contact when an impact occurs, and the floating magnet magnetically repels one of the magnets.

りによる誤動作が防止される。Effects According to this proposed structure, the floating element is always restrained to one side by the attractive force and repulsive force of a pair of magnets with different polarities, which solves the problem of chattering and prevents both sides in the event of a collision. It is emitted from one side by shaking off the magnetic force of the magnet, and is pressed against the other end of the housing by the repulsive force with the magnet on the other side, thus preventing malfunctions due to bounce.
実施例
以下本考案の構造ならびに作用効果を図面と共
に説明する。EXAMPLES The structure and effects of the present invention will be explained below with reference to the drawings.

１の他端側に配設された電気接点である。 FIG. 1 is a sectional view showing an example of the impact detection device of the present invention. In the figure, 1 is a non-magnetic cylindrical housing, and 2 and 3 are a pair of cylindrical permanent magnets with different polarities juxtaposed on one end side of the inner wall surface of this housing 1. N pole from one end on the inner wall surface of
It forms a south pole magnetic region. The cylindrical permanent magnets 2 and 3 were magnetized in the radial direction, but
It is also possible to use one with axial magnetization. 4 is a spherical floating magnet loaded in the space 5 in the housing 1, and has a polarity (S pole) different from the polarity (N pole) of the magnet 2 at one end of the pair of permanent magnets 2, 3. Surface magnetized. Further, reference numeral 6 denotes a vent hole provided through the wall of the housing 1 so that air compressed by the movement of the floating magnet 4 escapes to the outside. Reference numeral 7 denotes an electrical contact provided on the other end side of the housing 1.
尚、上記実施例では筒状永久磁石２，３を筐体１

配置する必要はなく、遊動磁石に所望の磁力を与
えられる位置であればどこでもよく、筐体の外部
等に配置するようにしてもよい。In the above embodiment, the cylindrical permanent magnets 2 and 3 are placed in the housing 1.
However, in the present application, the arrangement does not necessarily have to be this way, and may be placed anywhere as long as the desired magnetic force can be applied to the floating magnet, and it may be placed outside the casing or the like.

で移動しない。 When the impact detection device having such a configuration is attached to a vehicle, the axis of the casing 1 is aligned with the direction in which the impact force acts, for example, in the longitudinal direction of the vehicle, and the floating magnet 4 is moved against the casing by the impact force. It is attached so that it can move toward the other end. First, the floating magnet 4 is attached to one end side of the housing 1. In this state, the floating magnet 4 is attracted to the north pole of the magnet 2, and does not move due to deceleration or vibration caused by the vehicle control device. Even if it tries to move, it will be repelled by the S pole of the magnet 3 and will not move to the electrical contact side.

を著しく向上させることが出来る。 Here, both magnets 2 and 3 have the weight of the floating magnet 4,
The strength of the magnetic force is appropriately selected and set to operate at a level sufficient to detect the impact of the car (detection of the minimum impact value). Therefore, when the minimum impact value is exceeded, the floating magnet 4 overcomes the attractive force of the magnet 2 and the repulsive force of the magnet 3 and separates, moves to the other end of the housing 1, and closes the electric contact 7. Then, power is supplied to an external operating device (not shown) to open the gas supply valve and instantly fill the air bladder. What should be noted here is that the operation of the floating magnet 4 due to the above-mentioned impact is caused by the attraction of the magnet 2 being released when the vehicle decelerates due to sudden braking, etc., because a set of magnets 2 and 3 with different polarities are placed side by side. Even if the magnet 3 tries to move slightly apart, it will be repulsed by the magnet 3 and will be held on one end side, preventing any chattering. Furthermore, in the event of a sudden impact in a collision, the attraction and repulsion of the magnets 2 and 3 will be exceeded and the magnet 3 will separate. The reliability of the device can be significantly improved by preventing the electrical contacts from malfunctioning due to rebound caused by being forcibly pressed against the other end of the casing by the repulsive force of the magnet 3.
