Problems solved by technology

Obviously these devices limit the normal movement and operation of personnel and cannot be applied to actual combat and training
[0006] Therefore, in view of the problems of carrier-based aircraft landing, helicopter crash, parachute landing, manned airborne tank landing, etc., which have both vertical and horizontal impact overloads and are likely to cause cervical spine damage, a new type of protection system that does not affect normal operation is designed and developed. A simple and effective system device that can also play a protective role during impact has important military significance and social value for ensuring survivability and improving combat capabilities

Embodiment 1

[0027] Embodiment 1: see attached Figure 2-4 , a shock absorber and an anti-shock neck protection helmet system is characterized in that it includes a cylindrical outer cylinder 9, a self-controlled speed-limiting piston 10, an upper cover 8, a lower cover 11, and a lower spherical head connecting rod 7;

[0028] The two ends of the cylindrical outer cylinder 9 are respectively sealed by an upper cover 8 without air holes and a lower cover 11 with air holes;

[0029] The self-controlled speed-limiting piston 10 is arranged inside the cylindrical outer cylinder 9, including a piston body and two self-controlled speed-limiting valves 12, which can limit its own movement by controlling gas exchange;

[0030] There are two cylindrical cavities on the piston body, and the self-control speed-limiting valve 12 is embedded and fixed in the cylindrical cavities, and the axis of the cylindrical cavities is parallel to the axis of the piston body;

[0031] The self-controlled speed-lim...

Embodiment 2

[0035] Embodiment 2: see attached Figure 1-4 , an impact-resistant neck protection helmet system, characterized in that it comprises a helmet 1, two buffers as claimed in claim 1, a universal joint seat pad 3, and a shoulder pad 4;

[0036] The upper cover 8 of the buffer is fixedly connected with an upper spherical head connecting rod 7'; the upper spherical head connecting rod 7' and the lower spherical head connecting rod 7 are respectively equipped with a universal joint seat cushion 3;

[0037] The universal joint seat cushion 3 is composed of an upper ball cover 20, a lower ball cover 19 and a gasket 18. The upper ball cover 20 and the lower ball cover 19 are screwed to form a universal joint spherical space. The spherical head connecting rod 7' or the ball head of the lower spherical head connecting rod 7 is placed therein, and the lower ball cover 19 is fixed on the gasket 18;

[0038] Described shoulder pad 4 comprises: the shoulder belt that is tied on two shoulder...

Embodiment 3

[0041] Embodiment 3: see attached Figure 1-4 , according to the impact-resistant neck protection helmet system described in Embodiment 2, it is characterized in that the inner diameter of the buffer 2 is 20 mm to 35 mm, and the diameter of the air hole 13 is 2 mm to 5 mm.

Abstract

The invention relates to aerospace special lifesaving medical protective equipment, in particular to an impact-protection helmet system. According to the technical scheme, a buffer is characterized by comprising an outer cylindrical tube (9), a self-control speed-limiting piston (10), upper seal cover (8), a lower seal cover (11) and a lower spherical head connection rod (7). A shock-resistant and neck-protective helmet system is characterized by comprising a helmet (1), two buffers, a universal joint base cushion (3) and a shoulder-protection cushion (4). When the head is impacted, the buffers have the protective effect, and kinetic energy acted on the cervical vertebra when the worn helmet experiences impact load in the vertical or horizontal direction is absorbed and reduced, so that the cervical vertebra is protected against being hurt. The system is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to aerospace special life-saving medical protective equipment, in particular to a shock absorber and a shock-proof helmet system. Background technique [0002] When a pilot ejects, a carrier-based aircraft lands, a helicopter crashes, a parachute lands, and a manned airborne tank lands, large shock loads will be generated in the vertical and horizontal directions, which will easily cause damage to the cervical spine of the personnel. If an ordinary helmet is worn, due to the change of the mass characteristics of the head and the offset of the center of mass, the load on the cervical spine of the person will be further increased, and the probability of neck injury will be increased. [0003] There are some documents and patent reports on the invention and research of the cervical protection device. According to the direction of protection, it is mainly divided into three categories: one is the support system to prevent horizontal ...
