Description

Apparatus for buffering and absorbing external shock and reducing impact speed of an object to be impacted

The disclosed subject matter relates to an apparatus for buffering and absorbing an external impact of an object to be impacted and reducing an impact velocity.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and it is not admitted that the material described in this section is prior art.

A conventional vehicle structure is composed of a rigid bumper and a vehicle body, which are materials that cannot absorb shocks on the front and rear surfaces, and the vehicle body is damaged and compressed due to a collision. Damage and deformation of these plastic or steel materials cause fatal injuries to occupants, and the damaged objects strike or stab the human body, resulting in secondary injury and human casualties.

In addition, even when the shock absorber is installed on the object to be impacted, it is installed only on the impact surface where the impact occurs and buffers and absorbs the impact only at the impact generating part. In this case, the buffering and absorbing space at the impact surface is small and the depth at which devices such as springs operate is short, so that the impact is not effectively buffered and absorbed. There are problems that cause major damage, such as accidents.

1 is a schematic view of a state of use of an apparatus 900 for absorbing and absorbing external impact of an impact target according to an embodiment of the disclosed subject matter and reducing impact velocity, and FIG. A side view of the shock absorbing unit 100 of the external shock absorbing and absorbing and shock speed reducing device 900, and FIG. A schematic coupling diagram of the impact buffering unit 100 and the support unit 200, and FIG. 5 is a twisted line of the device 900 for absorbing and absorbing external impact of an impact target and reducing impact speed according to an embodiment of the present disclosure ( It is a schematic diagram of a) and a string (b) with protrusions 121.

It is possible to alleviate the external impact by dispersing the shock and reducing the speed of the object to be impacted by installing an impact speed reducing device. An apparatus 900 for buffering and absorbing external impact of an impact object and reducing impact speed according to an example of the present invention includes an impact buffer unit 100, a support unit 200, deceleration elastic units 310 and 320, and a deceleration pad unit ( 410 and 420), and the connection part 500 and the like. For example, the object to be impacted used in this specification may include any means of transportation such as a car or a train, and may include objects that collide with each other. Also, as an example, the deceleration elastic parts 310 and 320, the deceleration pad parts 410 and 420, the replacement parts 411 and 421, the sensor part, and the connection part 500, which will be described later, include not only cars but also wheels such as trains. can be applied to moving objects.

The apparatus 900 for absorbing and absorbing external shock of an object to be impacted and reducing the impact speed according to the present invention absorbs and transmits an external impact by mitigating and absorbing an impact shock absorber unit 100 and shock absorber unit 100 to receive an impact It includes a support unit 200 attached to the body, and the shock absorbing unit 100 is connected to both sides of the elastic part 110, which alleviates and absorbs external shock, and absorbs and transmits external shock. It includes an elastic transmission part 120 that supports the elastic transmission part 120 and a connection fixing part 130 coupled to an object to be impacted, and one side of the impact to the object to be impacted is applied to a plurality of surfaces of the object to be impacted. It is transmitted and absorbed to the entirety of the plurality of shock absorbing units 100 connected and installed through the connection fixing part 130 to mitigate external impact. The elastic transmission part 120 includes a twisted string in which a plurality of strings are twisted with each other or a twisted string including a string with a protrusion 121 twisted with each other, and the connection fixing part 130 is connected to the elastic transmission part 120 and the adjacent The elastic transmission part 120 of the shock absorbing unit 100 is connected and supported, and the elastic transmission part 120 of the different shock absorbing units 100 connected by one connection fixing part 130 is integrally formed. The shock absorbing unit 100 may further include a case portion 140 for accommodating and protecting the elastic portion 110 .

The shock absorbing unit 100 of FIGS. 1 to 4 mitigates and absorbs an impact applied to an object to be impacted from the outside and transmits it to the neighboring shock absorbing unit 100, mitigating and absorbing the external impact to apply to the occupant The support may serve to mitigate impact, and may include an elastic part 110, an elastic transmission part 120, a connection fixing part 130, and a case part 140.

As can be seen in the example of FIG. 1, for example, an impact applied to one shock absorbing unit 100 (S1) elongates the elastic part 110, which will be described later, by the elastic transmission part 120, which will be described later. is transmitted to the elastic transmission part 120 of the other shock absorbing unit 100 (S2), which is transmitted to the elastic part 110 of the other shock absorbing unit 100 (S2), and the shock is absorbed and buffered to form the elastic part 110 is elongated and accordingly transmitted to the elastic part 110 of another neighboring shock absorbing unit 100 (S3) by the elastic transmission unit 120 so that the impact is dispersed so that the applied impact can be buffered and absorbed.

As can be seen in the example of FIG. 1 or 2 , the elastic part 110 may play a role of alleviating and absorbing external impact. For example, the elastic part 110 may include a spring, and a plurality of springs may be connected in parallel or in series.

For example, the twisted line may include two or more smooth lines twisted with each other, a smooth line and a line with protrusions 121 twisted with each other, or two lines with protrusions 121 twisted with each other.

For example, the twisted line may include at least one line having protrusions 121 to form one twisted line. The line with protrusions (thorns or cogs) 121 becomes thicker in areas with protrusions 121 and thinner in areas without protrusions 121. As the surfaces are twisted in contact with each other because they are different, a gap is generated by contacting and bending due to different surface conditions, resulting in an empty space between the protrusions 121 and 121. If you pull the twisted string with an empty space like this, the space narrows and the bent twisted string stretches. That is, even if the thickness of the line is constant and the smooth line is twisted with each other, the tension increases, but almost no elasticity occurs.

In addition, when two strings are twisted to form a single twisted string, even if the cross-sectional areas of one smooth string and the twisted string are the same, the twisted string has much stronger tensile strength than the single smooth string, so durability can be greatly improved. Therefore, when a twisted string is used, the elasticity transmission unit 120 does not break, so durability can be greatly improved.

In addition, as an example, the elastic transmission unit 120 may be a line with a normal smooth line or a line with a protrusion 121.

For example, the connection fixing part 130 has a rod shape, and one side is coupled to the impact object, and the elastic transmission part 120 may be closely attached to the side and supported so as to move.

For example, as can be seen in the example of FIG. 1 or 2, the connection fixing part 130 connects one elastic transmission part 120 and the elastic transmission part 120 of the neighboring shock absorbing unit 100 to can support For example, the elastic transmission units 120 of the neighboring shock absorbing units 100 connected by the connection fixing unit 130 may be integrally formed.

For example, as can be seen in the example of FIG. 1 or 2, the case part 140 serves to accommodate and protect the elastic part 110, and the elastic transmission part 120 includes a hole through the hole. Through the case portion 140 may be extended to the outside.
