Example 3: further design is made on the basis of example 1

As shown in fig. 4-5, a helmet with adjustable internal filler comprises a helmet shell 1, filler 2, a circuit board 4, a plurality of groups of adjusting modules 3 and a plurality of groups of pressure collecting modules 5; the filler 2 is fixedly connected to the inner side wall of the helmet shell 1; the adjusting module 3 comprises a coil 31 and iron sheets 32, the coil 31 is embedded between the helmet shell 1 and the filler 2, the iron sheets 32 are fixedly connected to the inner side wall of the filler 2, the inner side wall of the filler 2 is full of the iron sheets 32, and the positions of the coil 31 and the positions of the iron sheets 32 are in one-to-one correspondence; the circuit board 4 is placed in the helmet shell 1, and the pressure acquisition module 5 is fixedly connected to the lower surface of the iron sheet 32; the number of the adjusting modules 3 is consistent with that of the pressure collecting modules 5; the circuit board 4 is provided with a controller, the adjusting module 3 is electrically connected with the controller, and the controller is used for controlling the action of the adjusting module 3 to adjust the shape of the filler 2 so as to compress and deform the filler 2; the pressure acquisition module 5 is electrically connected with the controller, and the controller can judge the signals acquired by the pressure acquisition module 5 and send instructions to the corresponding adjusting module 3. The circuit board 4 is further provided with a power supply module, the power supply module is electrically connected with the controller, and the power supply module is used for supplying electric energy to the controller. The power supply module comprises a rechargeable battery.

The circuit board 4 is further provided with a charging module, the charging module is electrically connected with the controller, the charging module is electrically connected with the power supply module, and the charging module is used for charging the power supply module by an external power supply.

Still be equipped with the status indication module on circuit board 4, have electric connection between status indication module and the controller, the status indication module can show whether power module is in the power shortage state, can also show whether external power source is in the state of charging to power module, can also show whether power module has been full of. The state indicating module comprises three indicating lamps of yellow, red and green, and when the controller detects that an external power supply charges a battery in the power supply module, the controller sends an instruction for lighting the yellow indicating lamp to remind people; when the controller detects that the external power supply stops charging the battery in the power supply module, the controller sends out an instruction of turning off the yellow indicator lamp. When the controller detects that the battery voltage in the power supply module is lower than Vmin of preset voltage, namely when the battery is in the power-off state, the controller sends an instruction for lighting the red indicator lamp, and the green indicator lamp is in the off state, so that people are reminded that the battery power is in the power-off state and the battery needs to be charged in time, the battery power is effectively prevented from being in the power-off state for a long time, and the service life of the battery is further influenced. When the controller detects that the battery voltage in the power supply module is not lower than Vmin of preset voltage, namely the battery is in the state of not short of power, the controller sends the instruction of lighting the green indicating lamp, and makes the red indicating lamp be in the off state, reminds people that the battery power is in the state of not short of power, need not to charge for the battery, can effectively avoid the battery to be in the state of being charged for a long time, and then reduced the injury to the battery.

The charging module comprises a USB male port, and the USB male port is electrically connected with the charging module.

The filling 2 may be a sponge. The sponge is a porous elastic material, has the cushioning effect, can effectively protect people's head safety, can be compressed, vacates the space after the compressed and gives the protruding usefulness of hair ligature department, can effectually avoid causing the painful sense of people's head because of the extrusion between the protruding of hair ligature department and the helmet.

The iron sheet 32 may be covered with a cloth cover. The cloth cover wraps the outer end of the iron sheet, one layer of buffer is added, and meanwhile, the harm to a human body caused by the fact that the iron sheet is too hard is reduced.

The iron piece 32 has a disc shape. The outer end of the disc-shaped iron sheet 32 is not provided with sharp-angled burrs, so that the injury to people is effectively avoided.

The pressure acquisition module 5 may be a thin film pressure sensor. The film type pressure sensor can be attached to a disc-shaped iron sheet, and the occupied space is small.

The helmet shell is provided with a female buckle matched with the USB male opening.

And a cable is electrically connected between the USB male port and the charging module.

The outer end of the cable is wrapped with a cable protective sleeve. The protection sleeve can effectively protect the cable from being pulled and broken, and can be used as a helmet protection belt to prevent the skin of people from being damaged due to too coarse contact with the neck of people.

Public mouthful of USB with connect the cable conductor between public mouthful of USB and the module of charging and with the female buckle that public mouthful of USB matches, when people wear the helmet overhead, with public mouthful of USB and female buckle lock together, the cable conductor of connecting between public mouthful of USB and the module of charging can regard as the helmet guard band to use, has effectively practiced thrift the cost, has improved the utilization ratio of material. The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
