Further, the invention adopts the technical scheme, and has the following advantages:

the suspension system consists of the buffer component, the suspension component and the buffer filler block which are arranged in the helmet body, and because the formed pressure can be gradually transmitted by using a simple date-core-shaped structure, the pressed area is gradually increased, and the problem of large impact force on the top of the head is effectively solved.

The components of the invention can be made of different materials, can exert respective advantages to the maximum extent, and if the woven belt is made of flame-retardant aramid fiber material, the invention has the characteristics of flame retardance, high tensile strength, light weight, flexibility, good aging resistance and long service life.

The EVA material (without limitation to color) is light, but has high tensile strength and higher compression times, and can further disperse and buffer the pressure transmitted by the woven tape.

Four straight keyholes on waterproof silk cloth upper layer of washing can retrain two buffering meshbelts effectively, makes buffering cushion and buffering meshbelt link into an organic whole, and the top of the head stress zone is stable when playing to wear, also can finely tune stress zone center according to everyone's difference, improves helmet and wears stability.

Ventilative eyelet fabric right angle end reverse side hasp fine hair links to each other with the helmet front brain gum hasp colludes, and other end fillet end reverse side hasp fine hair links to each other with two meshbelt hasp fine hairs, has further improved the relative stability of meshbelt to make whole buffering subassembly organically constitute a buffering whole.

The technical scheme of the invention ensures that the final stress of the vertex is less than 4900N, and the measured value is 2600N-3200N.

The head circumference adjusting device adopts the flexible wires to replace the materials such as plastic parts and woven belts which are used in the prior art to adjust the head circumference. Because the flexible wire has large tension and is fine and soft, the head of a person is surrounded by the high-elastic, comfortable and breathable protective sleeve, and the knob can be rotated by one hand to adjust the tightness of the head circumference, so that the device is quick and convenient.

According to the chin rest pressure tightness adjustment device, the tightness degree of the braid at the middle section of the left and right adjusting belts connected with the chin rest can be adjusted respectively by using the four trapezoidal buckles, and the chin rest pressure tightness adjustment device is convenient and quick. The chin support lining is made of superfine fiber suede leather fabric, is soft and can deform, is tightly attached to the skin of a human body, does not have hard foreign body feeling, and is very comfortable in body feeling. The flame-retardant woven belt is light and soft, and is attached to the cheek of a person, so that the body feeling is good.

According to the invention, through the design of the front, rear, left and right buffer filler blocks of the helmet, the impact protection in the direction of the side wall of the helmet can be effectively provided, and the head of a wearer can be protected from being injured by external impact in all directions to a greater extent.

The reasonable material selection and mutual advantage complementation of each part of the invention not only meet the requirement of impact resistance and shock absorption of the helmet, but also fully consider the problems of ventilation of the head top and the surrounding parts when the helmet is used, therefore, the head top part adopts a suspended design and leaves a ventilation space. The front, back, left and right buffer filler blocks are designed at large intervals, a large ventilation channel is reserved, and meanwhile, the contact part of the front, back, left and right buffer filler blocks and the skin of the surface of a human body are made of sweat-absorbing, moisture-conducting and quick-drying materials, so that the wearing comfort of the helmet is improved.

The invention has the advantages of ingenious and novel structural design and light overall weight, has the characteristic of good shock resistance within 200 g, solves the problem of inconvenient adjustment of the head circumference, can conveniently adjust the tightness of the head circumference and the chin rest according to requirements even in a wearing state, ensures that the helmet is stable, fit and portable in wearing, is convenient to fasten and greatly improves the safety protection performance. Therefore, the suspension system can be widely used in the suspension system inside the helmet.

In a word, according to the technical scheme, a helmet wearing person can conveniently adjust the head circumference by one hand at any time, and the lengths of the left and right side adjusting belts are adjusted by one hand, so that the chin pressure is conveniently adjusted at any time. The whole set of suspension system of the helmet is convenient to adjust in tightness and comfortable to wear, and has good buffering protection performance on the top of the head and in the front, back, left and right directions.
