Dynamic stent 4 stretches out or withdraws sliding slot, so as to adjust strap length, have adjusted elasticity.
As shown in Figure 1, bandage is made of upper casing 1 and lower casing 2, the space between upper casing 1 and lower casing 2 forms sliding slot.Upper casing 1
Combination can be clamped with lower casing 2, or is connected by screw combination.Electromagnet 5 may be mounted on lower casing 2.
Magnet piece 6 is permanent magnet, and magnetic direction is fixed, and can be disposed as upper end N poles as shown in Figure 8, Figure 9, lower end S
Pole.
The position of magnet piece 6 and electromagnet 5 can also exchange, and be provided with electromagnet 5 on sliding support 4, edge in sliding slot
The both ends for glide direction are both provided with magnet piece 6, have the technical effect that identical.
Bandage can be provided with sliding slot and sliding support 4 in either end, or both ends are both provided with sliding slot and sliding support
4, bandage is both provided with sliding slot and sliding support 4 at both ends in the present embodiment.
5 control device of electromagnet can be set on helmet, control electromagnet 5 to change magnetic direction manually, may be used also
With using intelligent control method, it is preferred to use intelligent control method.
As Figure 1 and Figure 4, some pressure sensors 3 are installed on the inside of bandage, pressure sensor 3 connects master controller,
Master controller connects electromagnet 5, and pressure sensing 3 detects pressure value when user wears helmet, and pressure value is sent out
Send to master controller, master controller controls electromagnet 5 to change the magnetic direction of itself according to the size of pressure value.
The setting position of these pressure sensors 3 is the position on bandage fitting user head, so to pressure sensor 3
Extruded, be bonded, pressure sensor 3 can provide pressure value as reference.Multiple pressure sensors 3, Ke Yiti are set
The reliability of high detection and sensitivity.
Chucking power scope P1-P2 built in system, chucking power scope can write master controller (control core by system software
Piece), master controller can be separately provided or the master controller using helmet, the pressure value that pressure sensor 3 detects
For P.
As P ＜ P1, bandage chucking power is too small at this time, the situation that helmet comes off easily occurs and is propped up, it is necessary to slide
Frame is tightened, and is started electromagnet 5 and is driven sliding support 4 to withdraw sliding slot, until P1≤P≤P2, electromagnet 5 keeps current flow number
Value, makes sliding support 4 maintain current state.
As P ＞ P2, bandage chucking power is excessive at this time, easily causes headache etc. no using helmet at elevated pressures for a long time
Good impression is loosened, it is necessary to carry out sliding support and stretch out, and starts electromagnet 5 and drives sliding support 4 to stretch out sliding slot, until P1≤P≤
P2, electromagnet 5 keep current flow numerical value, sliding support 4 is maintained current state.
As shown in Figure 2 and Figure 3, two magnet pieces 6 in left and right are installed on sliding support 4, correspond to sliding slot upper and lower ends respectively
Electromagnet 5.Two 5 sequence of electromagnet arrangements, can be effectively prevented from electromagnet 5 and interfere with each other, and whole system is in flat
Weighing apparatus state.

Mounting hole 4-5 is provided with connecting plate 4-2, for mounting elastic sheet 9, forearm 4-1, postbrachium 4-3 are close to connecting plate 4-2
Position be also equipped with mounting hole 4-5, for installing magnet piece 6, sliding support 4 stretches out the company of being provided with the tailgate 4-4 of sliding slot
Lug 4-6, for connecting wearable device.
Sliding support 4 is arranged using " Z " font, makes sliding distance longer, the limitation for solving 5 zone distance of electromagnet,
Adjustable extent is longer.
As shown in Figure 5, Figure 6, shrapnel 9 is provided with sliding support 4, zigzag card slot 7 is provided with sliding slot, shrapnel 9 is in
Triangle, shrapnel 9 are moved to sliding support 4 in card slot 7 into row buffering and spacing.In 4 moving process of sliding support, electromagnet
Electric current can be lifted gradually so that 5 magnetism of electromagnet becomes larger, and shrapnel 9 is movable in zigzag card slot 7, which can keep away
It is excessive and cause acutely to feed back to exempt from 5 magnetic force of electromagnet, buffering is realized by the way of flexible feedback, avoids sliding support 4 from moving
It is too fast.
The position of shrapnel 9 and card slot 7 can also exchange, and shrapnel 9 is provided with sliding slot, saw is provided with sliding support 4
Dentation card slot 7, the movement in card slot 7 of shrapnel 9 are spacing to sliding support 4.
When needing to tighten bandage, as shown in figure 8, the electromagnet 5 on top is adjusted to upper end N poles, lower end S poles, to magnet piece 6
Attraction is produced, the electromagnet 5 of lower part is adjusted to upper end S poles, and lower end N poles, produce repulsive force, so as to drive cunning to magnet piece 6
Dynamic stent 4 withdraws sliding slot along arrow direction indication.
When needing to loosen bandage, as shown in figure 9, the electromagnet 5 on top is adjusted to upper end S poles by reverse current conversion,
Lower end N poles, produce repulsive force, the electromagnet 5 of lower part is adjusted to upper end N poles, and lower end S poles, produce magnet piece 6 to magnet piece 6
Attraction, so as to drive sliding support 4 to stretch out sliding slot along arrow direction indication.
Embodiment 2
In the utility model embodiment 2, with embodiment 1 the difference is that be not provided with permanent magnet on sliding support 4 but
