Technical Field

The invention relates to the technical field of helmets, in particular to a high-protection power-assisted helmet assembly.

Background

In the military field: the death rate caused by head injury is much higher than that of other parts of the body during the battle, but the protection of the head is generally weaker than that of the currently mainstream military helmets relative to the importance of the head. The reason is mainly divided into two aspects: under the same technical process conditions, the increase of the protective force of the helmet certainly increases the weight. The overweight of the helmet can increase the pressure on the neck, easily cause the cervical vertebra injury, and also seriously affect the flexibility of the head action. Even if the helmet is equipped with a heavier and more protective strong helmet, when the helmet is subjected to a larger impact force, for example, when the helmet is shot by a 12.7mm machine gun to hit the head, even if the helmet is not punctured, the head of a wearer can be fatally vibrated by the huge impact force, and meanwhile, under the action of the inertia of the impact force, the cervical vertebra is very easy to be damaged.

In the civil field: helmets are very commonly used in the civil protection field and also have similar problems as in the military field. The weight of the helmet seriously affects the comfort and the flexibility of the head action, and the cervical vertebra can be damaged if the helmet is worn for a long time. Even if the helmet has good protection performance, when the helmet is impacted, the impact force can easily cause vibration to the head, and meanwhile, under the action of the inertia of the impact force, the cervical vertebra is very easy to be damaged.

Because the two ends of the flow limiting valve are provided with the conical heads 26, the flow rate of the hydraulic oil in two directions can be limited. Two electromagnetic coils 29 of the electromagnetic valve respectively control the corresponding sliding pistons 28 to move, when the oil passage needs to be closed, the electromagnetic coils control the sliding pistons 28 to slide out rightwards, so that the shaft core is driven to close the oil passage, and on the contrary, the sliding pistons 28 slide leftwards, and the oil passage is opened. The electromagnetic valve has two states of normally open and normally closed by the left and right movement of the sliding piston.

The working principle of the invention is illustrated by the following specific examples:

in the figure, the four hydraulic rods are a left front hydraulic rod 61, a right front hydraulic rod 62, a left rear hydraulic rod 63, and a right rear hydraulic rod 64, respectively. The four hydraulic boosters are respectively a booster I30 arranged between the left front hydraulic rod 61 and the right front hydraulic rod 62, a booster II 31 arranged between the left front hydraulic rod 61 and the left rear hydraulic rod 63, a booster III 32 arranged between the left rear hydraulic rod 63 and the right rear hydraulic rod 64, and a booster IV 33 arranged between the right front hydraulic rod 62 and the right rear hydraulic rod 64.

When the wearer acts on his own:

the first embodiment is as follows: in an unstressed state:

when a wearer stands, the four hydraulic rods tend to be in a vertical state, the difference of gravity values borne by the four hydraulic rods is small, most of weight of the helmet and the helmet connecting seat is directly transmitted to protective equipment of the trunk part of the wearer through the chest connecting seat or other exoskeleton structures used in a matched mode, and therefore the pressure of the neck is relieved. When the wearer rotates the head, the helmet is driven to rotate along the rotating direction of the bearing, and the head is rotated.

Example two: when the wearer does the head-up action:

the pressure sensor senses the backward acting pressure of the head, after the hydraulic booster receives signals, the gear pumps 22 in the second booster 31 and the fourth booster 32 are driven by the motor to rotate, and hydraulic oil in the oil chamber of the rear left hydraulic rod 63 flows into the oil chamber of the front left hydraulic rod 61 through the oil pipe. Meanwhile, the hydraulic oil in the lower oil chamber of the right rear hydraulic rod 64 flows into the lower oil chamber of the right front hydraulic rod 62 through the lower oil pipe, so that the assisted head-up action is realized.

Example three: when the wearer performs a head lowering action:

the pressure sensor senses the backward acting pressure of the head, after the hydraulic booster receives a signal, the gear pump 22 in the second booster 31 and the fourth booster 33 is driven by the motor to rotate, and hydraulic oil in the oil chamber of the front left hydraulic rod 61 flows into the oil chamber of the rear left hydraulic rod 63 through the oil pipe. Meanwhile, the hydraulic oil in the lower oil chamber of the right front hydraulic rod 62 flows into the lower oil chamber of the right rear hydraulic rod 64 through the lower oil pipe, so that the boosting head lowering action is realized.

Example four: when the wearer swings his head to the left:

the pressure sensor senses the pressure of the leftward movement of the head, after the hydraulic booster receives signals, the gear pumps 22 in the first booster 30 and the third booster 32 are driven by the motor to rotate, and hydraulic oil in the oil chamber of the left front hydraulic rod 61 flows into the oil chamber of the right front hydraulic rod 62 through the oil pipe. Meanwhile, the hydraulic oil in the lower oil chamber of the left rear hydraulic rod 63 flows into the lower oil chamber of the right rear hydraulic rod 64 through the lower oil pipe, so that the left swing motion of the assisting force is realized.

Example five: when the wearer swings his head to the right:

the pressure sensor senses the pressure of the rightward movement of the head, after the hydraulic booster receives signals, the gear pumps 22 in the first booster 30 and the third booster 32 are driven by the motor to rotate, and hydraulic oil in the oil chamber of the right front hydraulic rod 62 flows into the oil chamber of the left front hydraulic rod 61 through the oil pipe. Meanwhile, the hydraulic oil in the lower oil chamber of the right rear hydraulic rod 64 flows into the lower oil chamber of the left rear hydraulic rod 63 through the lower oil pipe, so that the assisted rightward swinging motion is realized

In conclusion, the wearer can also swing leftwards or rightwards when raising or lowering the head, and the four multifunctional hydraulic boosters can work simultaneously, so that the head can swing at all angles within a certain range.

When the wearer head received huge external force and assaulted, huge impact force can lead to the violent lateral shifting of helmet and helmet connecting seat, because the body of rod of four hydraulic stems all passes spacing hole and through stop collar fixed connection, has effectively restricted the amplitude of oscillation of four hydraulic stems to restricted the lateral shifting amplitude of helmet seat and helmet, played the effect of shocking resistance.

Furthermore, the piston in the four hydraulic rods can also be caused to move rapidly by the huge impact force, the hydraulic oil in the piston is driven to flow, when the flow rate of the hydraulic oil exceeds the limit value of the flow limiting valve, the flow limiting valve can press the spring to move towards the flowing direction of the hydraulic oil under the action of the hydraulic oil pressure, and the conical head at one end of the flow limiting valve can be attached to the oil passage hole to play a role in plugging the oil passage.

The following lists the specific working principle when the large impact force is applied to four different directions:

example six: when the head of the wearer is impacted by a great external force from front to back:

under the action of impact force, the left rear hydraulic rod 63 and the right rear hydraulic rod 64 are compressed, hydraulic oil in a lower oil chamber of the hydraulic rods is subjected to pressure, flows through lower oil chambers of the left front hydraulic rod 61 and the right front hydraulic rod 62 through lower oil pipes, and when the hydraulic oil flows through the second booster 31 and the fourth booster 33, a flow limiting valve in the hydraulic booster is subjected to impact force and then closes an oil channel. Meanwhile, the helmet pulls the left front hydraulic rod 61 and the right front hydraulic rod 62 upwards under the action of huge impact force, the oil chambers of the left front hydraulic rod 61 and the right front hydraulic rod 62 are compressed, the hydraulic oil in the hydraulic oil chambers flows to the oil chambers of the left rear hydraulic rod 63 and the right rear hydraulic rod 64 through the oil feeding pipe, and the hydraulic oil in the oil chambers of the left rear hydraulic rod 63 and the right rear hydraulic rod 64 cannot continuously flow in due to the fact that the oil passages of the oil chambers of the left rear hydraulic rod 63 and the right rear hydraulic rod 64 are sealed and the pistons in the hydraulic oil chambers cannot move downwards. Thereby furthest restricting the backward swing of the helmet and playing the role of impact resistance.

Example seven: when the wearer's head is impacted by a large external force from the rear to the front:

under the action of impact force, the left front hydraulic rod 61 and the right front hydraulic rod 62 are compressed, hydraulic oil in the lower oil chambers of the left front hydraulic rod 61 and the right front hydraulic rod 62 is subjected to pressure, flows to the lower oil chambers of the left rear hydraulic rod 63 and the right rear hydraulic rod 64 through the lower oil pipes, and when the hydraulic oil flows through the second booster 31 and the fourth booster 33, the flow limiting valve in the hydraulic booster is subjected to impact force and then closes the oil passage. Meanwhile, under the action of great impact force, the helmet pulls the left and right rear hydraulic rods 63 and 64 upwards to compress the oil chambers of the left and right rear hydraulic rods 63 and 64, the hydraulic oil in the hydraulic oil flows to the oil chambers of the left and right front hydraulic rods 61 and 62 through the oil feeding pipe, and because the oil passages of the oil chambers below the left and right front hydraulic rods 61 and 62 are sealed, the pistons in the oil chambers cannot move downwards, and the hydraulic oil in the oil chambers of the left and right front hydraulic rods 61 and 62 cannot flow into the oil chambers continuously. Thereby furthest restricting the forward swing of the helmet and playing the role of impact resistance.

Example eight: when the head of the wearer is impacted by a large external force from right to left:

under the action of impact force, the left front hydraulic rod 61 and the left rear hydraulic rod 63 are compressed, hydraulic oil in the lower oil chambers of the left front hydraulic rod 61 and the left rear hydraulic rod 63 is pressurized and flows to the lower oil chambers of the right front hydraulic rod 62 and the right rear hydraulic rod 64 through the lower oil pipes, and when the hydraulic oil flows through the first booster 30 and the third booster 32, the flow limiting valves in the second booster 30 and the third booster 32 are subjected to impact force to close oil passages. Meanwhile, under the action of huge impact force, the helmet pulls the right front hydraulic rod 62 and the right rear hydraulic rod 64 upwards to compress the oil chambers of the right front hydraulic rod 62 and the right rear hydraulic rod 64, hydraulic oil in the helmet flows to the oil chambers of the left front hydraulic rod 61 and the left rear hydraulic rod 63 through the oil feeding pipe, because the oil passages of the oil chambers under the left front hydraulic rod 61 and the left rear hydraulic rod 62 are closed, the piston in the helmet cannot move downwards, and the hydraulic oil in the oil chambers of the right front hydraulic rod 62 and the right rear hydraulic rod 64 cannot flow into the helmet continuously. Thereby limiting the left swing of the helmet to the maximum extent and playing a role in resisting impact.

Example nine: when the head of the wearer is impacted by a large external force from left to right:

under the action of impact force, the right front hydraulic rod 62 and the right rear hydraulic rod 64 are compressed, hydraulic oil in the lower oil chambers of the right front hydraulic rod 62 and the right rear hydraulic rod 64 flows to the lower oil chambers of the left front hydraulic rod 61 and the left rear hydraulic rod 63 through the lower oil pipe under the action of pressure, and when the hydraulic oil flows through the first booster 30 and the third booster 32, the flow limiting valves in the first booster 30 and the third booster 32 are subjected to the impact force to close the oil passages. Meanwhile, under the action of huge impact force, the helmet pulls the left front hydraulic rod 61 and the left rear hydraulic rod 63 upwards, the oil chambers of the left front hydraulic rod 61 and the left rear hydraulic rod 63 are compressed, hydraulic oil in the oil chambers flows to the oil chambers of the right front hydraulic rod 62 and the right rear hydraulic rod 64 through the oil feeding pipe, and because the oil passages of the oil chambers below the right front hydraulic rod 62 and the right rear hydraulic rod 64 are sealed, the piston in the oil chambers cannot move downwards, and the hydraulic oil in the oil chambers of the left front hydraulic rod 61 and the left rear hydraulic rod 63 cannot flow into the oil chambers continuously. Thereby limiting the helmet to swing rightwards to the maximum extent and playing a role in resisting impact. When the head of a wearer does not need to swing, the electromagnetic valve in the hydraulic booster can close the oil duct, so that the state of the hydraulic suspension assembly is kept fixed, and the bidirectional oil pump in the hydraulic booster is also kept in a power-off state, so that the energy consumption is reduced.

The invention can realize the rotation and swing of the head of a wearer and can relieve external impact. Through the innovation to hydraulic booster structure, make it possess the restriction velocity of flow simultaneously, open and close oil duct and helping hand function. The invention has good head bearing capacity, can effectively reduce the load pressure of the cervical vertebra and also has good impact resistance. The invention can also be matched with other protective equipment for use, and is particularly suitable for being matched with other exoskeleton equipment for use so as to achieve a very good overall protective effect. The invention can be used for military use or civilian use, can be applied to individual protective equipment, power-assisted helmet components of individual exoskeletons, power-assisted helmet components of explosion-proof clothes and the like in the military field, and can be applied to power-assisted helmet components of fire-fighting clothes, power-assisted helmet components of high-protection riding clothes and the like in the civilian field.
