Structure, including bandage (top news), bandage are made of some sections of band bodies, are connected between band body and are telescopically connected section 4, adjacent band body exists
Junction is respectively arranged with magnet piece 6 and electromagnet 5, and electromagnet 5 changes the magnetic direction of itself, adjacent by magnetic drive
Band body is made close to mobile or remote movement to change spacing, so as to adjust strap length, be have adjusted and is accommodated power size and elasticity.
Strap end is provided with attachment device (not shown) to connect helmet, such as headphone, VR virtual
Real world devices, the attachment device can be provided in the mounting hole with body, or interface arrangment.
In this embodiment, bandage is provided with four sections of band bodies, and the band body of high order end is only provided with magnet piece 6 in right end, in
Between two sections of band bodies be provided with electromagnet 5, right end to be provided with magnet piece 6 in left end respectively, the band body of low order end is set in left end
It is equipped with electromagnet 5.The position of magnet piece 6 and electromagnet 5 can also right and left mutually changing, have the technical effect that identical.
Magnet piece 6 is permanent magnet, and magnetic direction is fixed, and can be disposed as left end N poles as shown in Figure 6, Figure 7, right end S
Pole.
Guide rail 8 is connected between adjacent band body, the guiding band body of guide rail 8 moves, avoids causing bandage with dislocation between body
Shape distortion.Guide rail 8 is arc-shaped, and radian is consistent with body, and smooth slip can be effectively ensured, avoid interim card.
It is telescopically connected section 4 and uses rubber or silica gel material, can be compressed and stretched；It is telescopically connected 4 surface of section and is provided with ditch
Groove, groove vertical band body moving direction, sets groove to be more advantageous to being telescopically connected section 4 and compressed.
It is consistent to be telescopically connected the shape of section 4 and the shape with body, and cross section is all rectangle, and main function is to fill up phase
Gap between the body of adjacent band, allows bandage to keep overall appearance.Being telescopically connected 4 both ends of section can be solid with adjacent band body bonding respectively
It is fixed.
As shown in Fig. 2, Fig. 6, band body is made of upper casing 1 and lower casing 2, and the space between upper casing 1 and lower casing 2 forms inner cavity,
Locating slot 7 is provided with inner cavity magnet piece 6 or electromagnet 5 are installed, be provided with sliding slot on the outside of the cell wall of locating slot 7, guide rail 8 is in cunning
Slided in groove, there is during slip damping.
In band body moving process, electromagnet current can be lifted gradually so that 5 magnetism of electromagnet becomes larger, and guide rail 8 exists
In sliding slot slide have damping, the structure can be excessive to avoid 5 magnetic force of electromagnet and cause acutely to feed back, using flexible feedback
Mode realizes buffering, avoids band body from moving too fast.
Upper casing 1 and lower casing 2 can be clamped combination, or be connected by screw combination.Locating slot 7 is arranged on lower casing 2, with
Lower casing 2 is made into integration, and locating slot 7 can also be arranged on upper casing 1.
As shown in Figure 3, Figure 4, rectangle frame is provided with inner cavity, two long sides of rectangle frame are arc-shaped, form guide rail 8, rectangle
Frame entangles two locating slots 7, which can realize that guiding band body moves, the ultimate range that can be moved with restriction band body.
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 shown in Figure 1, shown in Figure 5, 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 adjacent band body to do close to movement, until P1≤P≤P2, electromagnet 5 keeps current flow
Numerical value, makes adjacent band body maintain current distance 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 adjacent band body to do away from movement, until P1≤P
≤ P2, electromagnet 5 keep current flow numerical value, adjacent band body is maintained current distance state.
When needing to tighten bandage, as shown in fig. 6, electromagnet 5 is adjusted to left end N poles, right end S poles, suction is produced to magnet piece 6
Gravitation, so as to drive adjacent band body to do close move along arrow direction indication.
When needing to loosen bandage, as shown in fig. 7, electromagnet 5 is adjusted to left end S poles, right end N by reverse current conversion
Pole, repulsive force is produced to magnet piece 6, so as to drive adjacent band body to do remote move along arrow direction indication.
Embodiment 2
In the utility model embodiment 2, with embodiment 1 the difference is that being not provided with permanent magnet with body right end but setting
Secondary electromagnet is equipped with, adjacent band body is provided with main electromagnet in junction, and main electromagnet changes the magnetic direction of itself, passes through
The adjacent band structural reform of magnetic drive becomes spacing.
During band structural reform becomes spacing, the magnetic direction of secondary electromagnet can keep left end N poles, and right end S is extremely constant,
Only change the magnetic direction of main electromagnet.
