Abstract

The utility model belongs to the technical field of the explosion-proof car, concretely relates to buffer layer structure of kinds of explosion-proof cushions, it has solved current explosion-proof car when the impact force that suffers the explosion, and the seat can not cushion the explosion impact force and cause discomfort or injury problem to the human body.

Description

Buffer layer structure of explosion-proof cushions

Technical Field

The utility model belongs to the technical field of explosion-proof car, concretely relates to buffer layer structure of kinds of explosion-proof cushions.

Background

The explosion-proof vehicle is kinds of multipurpose vehicles which are developed and produced aiming at the requirements of multiple tasks such as public security, rest group disturbance and violence, terrorist attack, armed guard and the like, and the explosion-proof vehicles such as communication vehicles, cash carriers, ammunition vehicles and the like play an important role in various fields.

For example, Chinese patent application No. CN201520906918.2 proposes kinds of folding seats for explosion-proof vehicles, which include a seat cushion, a back cushion, a backrest frame, a support and a folding mechanism, although the technical scheme can fold the seat for explosion-proof vehicles, when the explosion-proof vehicles travel on a section with land mines or other explosives or people throw explosives downwards towards the bottom of the vehicles, the seat cannot buffer the impact force of the explosion, and the impact force can cause discomfort or injury to human bodies, so how to reduce the impact force generated by the explosion to the human bodies is technical problems to be solved.

Disclosure of Invention

The utility model aims to solve the problems of the prior art and provides a buffer layer structure of kinds of explosion-proof cushions, which aims to solve the technical problem of how to reduce the impact force generated by explosion on human body.

The purpose of the utility model can be realized by the following technical proposal:

buffer layer structure of explosion-proof cushion, including the base plate, its characterized in that, the bottom surface of base plate has a plurality of cushion column that can take place elastic deformation, the cushion chamber has in the cushion column, seted up on the base plate with the communicating through-hole of cushion chamber.

When the bottom of the vehicle is impacted by explosion, the shock wave generated by the explosion can be transmitted to the buffer layer structure firstly, the buffer column of the buffer layer structure bears the impact, and the buffer column is internally provided with the buffer cavity communicated with the outside, so that the buffer column can smoothly generate elastic deformation to absorb the impact force when being impacted, and the impact generated by the explosion is avoided or reduced to influence the human body.

In the buffer layer structure of the explosion-proof cushion, the buffer column is in a circular truncated cone shape with a large upper part and a small lower part. The round-table-shaped buffer column with the large upper part and the small lower part can better diffuse and absorb the impact of explosion, and the impact generated by explosion on a human body is reduced.

In the buffer layer structure of the explosion-proof cushion, the buffer columns are arranged on the substrate in a rectangular array. The rectangular array of buffer posts on the substrate enables the buffer posts to be uniformly arranged on the substrate.

In the buffer layer structure of the anti-explosion cushion, the height of the buffer column is 60-120 mm. The bumper posts have a high height that provides sufficient distance to absorb blast impact cushioning.

In the buffer layer structure of the explosion-proof cushion, the through hole is in a shape of a large upper part and a small lower part. When the buffering post receives explosion impact compression, the gas in the buffering intracavity can be from through-hole department towards the human injection, can reduce the pressure of air current when making the through-hole be big-end-up's reaming form.

In the buffer layer structure of the anti-explosion cushion, the base plate and the buffer column are formed by the flexible sheet , the flexible sheet can be deformed better, and the influence of impact generated by explosion on a human body is reduced.

Compared with the prior art, this buffer layer structure of explosion-proof cushion has following advantage:

the impact force generated by explosion is absorbed through the deformation of the buffer column, and the impact force generated by the explosion on a human body is reduced.

Detailed Description

The following is a description of the technical solution of the present invention in steps with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the embodiment of the utility model provides a including base plate 1, base plate 1 fixes in the vehicle cushion below, and base plate 1's bottom surface 4 is equipped with the buffering post 2 that deformation can take place for a plurality of, and base plate 1 is the rectangle, and buffering post 2 arranges the setting along base plate 1's length direction or width direction array, has cushion chamber 3 in the buffering post 2, has seted up on base plate 1's the top surface 5 with the communicating through-hole 6 of cushion chamber 3, and through-hole 6 is big-end-up's reaming form. When the vehicle bottom receives the explosion and assaults, the produced shock wave of explosion can transmit earlier to the buffer layer structure that is located vehicle cushion below, and buffer column 2 of buffer layer structure bears the impact, because have in buffer column 2 with outside communicating cushion chamber 3, make buffer column 2 can be smooth when suffering from the impact take place deformation absorption impact force, avoid or reduce the impact that the explosion produced and cause the influence to the human body. When the buffering post receives explosion impact compression, the gas in the buffering intracavity can be from through-hole department towards the human injection, can reduce the pressure of air current when making the through-hole be big-end-up's reaming form.

As shown in fig. 2 and 3, the buffer column 2 includes a deformation portion, the top end of the deformation portion is connected to the substrate 1, the bottom end of the deformation portion is provided with an impact buffer portion, a round corner is arranged between the impact buffer portion and the deformation portion, and the buffer column 2 can be in a round table shape with a large top and a small bottom. In actual processing, the buffer posts 2 may be in the shape of prisms having large top and small bottom. The height of the buffer column 2 is 60-120mm, and the distance for absorbing and buffering explosion impact is enough.

This buffer layer structure of explosion-proof cushion has flexible sheet body shaping, and flexible sheet can be rubber, plastic or have elastic deformation's metal material.

This buffer layer structure of explosion-proof cushion can be the setting between cushion and seat skeleton, fixes in the bottom of cushion, perhaps lies in inside the cushion, by the inside filler parcel of cushion.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
