In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] This embodiment provides a smart helmet. Figures 1 to 4 As shown, the smart helmet includes a helmet body 1 and a control module 2, an earpiece 41, a microphone 42 and a breathing control component 5 arranged in the helmet body 1. The earpiece 41, the microphone 42 and the control module 2 can be respectively connected to the mobile terminal for communication, and the mobile terminal has the functions of talking and multimedia playing. The breathing control component 5 includes a tube body 51, a diaphragm 52 and a pressure sensor 53. The pressure sensor 53 is fixed in the helmet body 1 and is connected to the control module 2 for communication. The first end of the tube body 51 is arranged on the pressure sensor 53, and the diaphragm 52 is arranged in the tube body 51. The diaphragm 52, the tube body 51 and the pressure sensor 53 jointly form an air cavity 501. When the wearer of the helmet body 1 inhales or exhales toward the second end of the tube body 51, the diaphragm 52 can be deformed and the pressure in the air cavity 501 can be changed to adjust the pressure acting on the pressure sensor 53. The control module 2 can switch the talking state of the mobile terminal according to the change of the pressure on the pressure sensor 53.

[0047] In this embodiment, the mobile terminal has call and multimedia playback functions. Exemplarily, the mobile terminal may be a smart phone. The multimedia playback of the mobile terminal includes video playback, music playback, voice audio playback, etc.

[0048] In this embodiment, the air cavity 501 formed by the diaphragm 52, the tube body 51 and the pressure sensor 53 is closed. This arrangement ensures that the pressure sensor 53 can reliably and effectively sense changes in pressure.

[0049] In this embodiment, the wearer can make and receive calls through the earpiece 41 and the microphone 42 while wearing the smart helmet. By setting a breathing control component 5, it includes a tube body 51, a diaphragm 52 and a pressure sensor 53. The second end of the tube body 51 can correspond to the mouth of the wearer. When the wearer of the helmet body 1 inhales or exhales toward the second end of the tube body 51, the diaphragm 52 can be driven to deform, thereby changing the pressure in the air cavity 501 to adjust the pressure acting on the pressure sensor 53. The control module 2 can switch the call state of the mobile terminal according to the change in the pressure on the pressure sensor 53, thereby realizing the switching control of the call state of the mobile terminal. The structure is simple and the operation is convenient. The risk of the wearer's hand accidentally touching the physical button in the prior art is effectively avoided, and the reliability of use is high and the operation efficiency is high.

[0050] Specifically, the second end of the tube body 51 is provided with an air port 511 , and the air breathed by the wearer of the helmet body 1 can enter the tube body 51 through the air port 511 and act on the diaphragm 52 .

[0051] Furthermore, the smart helmet includes a wireless communication module 3, the wireless communication module 3 is communicatively connected with the control module 2, and the earpiece 41, the microphone 42 and the control module 2 are communicatively connected with the mobile terminal through the wireless communication module 3 respectively.

[0052] For example, the wireless communication module 3 can be configured as a Bluetooth communication module. The communication connection process between the Bluetooth communication module and the receiver 41, the microphone 42 and the control module 2 is a prior art and will not be described in detail here.

[0053] Optionally, the smart helmet is also provided with an antenna 43. The setting of the antenna 43 can better transmit communication signals, ensure the reliability and stability of the wireless communication module 3, and better ensure the communication connection between the earpiece 41, the microphone 42 and the control module 2 and the mobile terminal.

[0054] For example, the control module 2 can be set as a single chip controller. The principle and process of the control module 2, the receiver 41, and the microphone 42 realizing communication connection with the mobile terminal through the wireless communication module 3 are prior arts, and will not be described in detail here.

[0055] Further, the call state of the mobile terminal includes a call state and a hang-up state. The control module 2 is adapted to control the mobile terminal to switch from the hang-up state to the call state, or to control the mobile terminal to switch from the call state to the hang-up state when the pressure on the pressure sensor 53 reaches a first threshold. For example, Figure 4 The figure shows a functional schematic diagram of a smart helmet provided by one embodiment. Specifically, when the wearer of the helmet body 1 exhales toward the second end of the tube body 51, the diaphragm 52 is deformed and concave toward the first end of the tube body 51, increasing the pressure in the air cavity 501. The pressure value of the air cavity 501 changes and acts on the pressure sensor 53. The pressure sensor 53 continuously transmits the pressure signal to the control module 2. When the pressure acting on the pressure sensor 53 reaches the set first threshold, the control module 2 controls the mobile terminal to switch the call state through the wireless communication module 3 after receiving the pressure signal transmitted by the pressure sensor 53.

[0056] Specifically, when the mobile terminal is in the hang-up state, that is, not in a call state, the mobile terminal switches to the call state, that is, the call is connected; when the mobile terminal is in the connected state, that is, the call is connected, the mobile terminal switches to the hang-up state, that is, the call is hung up.

[0057] Exemplarily, the first threshold is set in the control module 2 , and the set value may be 5 atm (Automatic Teller Machine, atmospheric pressure).

[0058] Furthermore, the mobile terminal has a multimedia playing state and a multimedia pause state. The control module 2 is adapted to control the mobile terminal to switch from the multimedia playing state to the multimedia pause state, or to control the mobile terminal to switch from the multimedia pause state to the multimedia playing state when the pressure on the pressure sensor 53 reaches a second threshold. Figure 4 As shown, when the wearer of the helmet body 1 inhales air through his mouth toward the second end of the tube body 51, the diaphragm 52 is deformed and concave toward the second end of the tube body 51, thereby reducing the pressure in the air cavity 501. The pressure value of the air cavity 501 changes and acts on the pressure sensor 53. The pressure sensor 53 continuously transmits the pressure signal to the control module 2. When the pressure acting on the pressure sensor 53 reaches the set second threshold, the control module 2 controls the mobile terminal to switch the call state through the wireless communication module 3 after receiving the pressure signal transmitted by the pressure sensor 53.

[0059] Specifically, when the mobile terminal is in a multimedia playback state, that is, playing audio, video or voice message, the mobile terminal switches to a multimedia pause state, that is, pausing the playback of audio, video or voice message; when the mobile terminal is in a multimedia pause state, that is, pausing the playback of audio, video or voice message, the mobile terminal switches to a multimedia playback state, that is, continuing to play the audio, video or voice message.

[0060] Exemplarily, the first threshold is set in the control module 2, and the set value may be 0.5 atm.

[0061] Furthermore, the second end of the tube body 51 is sleeved with a first soft sheath 54. The provision of the first soft sheath 54 can prevent the hard surface of the tube body 51 from hard contact with the wearer's face, mouth and other parts, thereby better protecting the wearer.

[0062] Exemplarily, the material of the first soft sheath 54 is set to be silicone.

[0063] In this embodiment, the smart helmet also includes a tongue control component 6, which includes a bracket 61 and a tongue control push rod 62. The bracket 61 is fixed in the helmet body 1, and the tongue control push rod 62 is communicatively connected to the control module 2. The tongue of the wearer of the helmet body 1 can push the tongue control push rod 62 to change its position, and the control module 2 can adjust the multimedia playback state of the mobile terminal according to the position of the tongue control push rod 62. Specifically, the change of the multimedia playback state of the mobile terminal is achieved by controlling the direction of the tongue movement, and can also replace the physical button control of the prior art, avoid the risk of accidental touch, simplify the action process, and ensure the efficiency and reliability of the operation.

[0064] Furthermore, the control of the multimedia playback state of the mobile terminal includes: volume up, volume down, previous song switching and next song switching. Figure 4 As shown in the example, when the tongue-controlled push rod 62 is pushed upward to the first position, the control module 2 can control the volume of the mobile terminal to be turned up; when the tongue-controlled push rod 62 is pushed downward to the second position, the control module 2 can control the volume of the mobile terminal to be turned down; when the tongue-controlled push rod 62 is pushed to the left to the third position, the control module 2 can control the mobile terminal to switch to the previous song; when the tongue-controlled push rod 62 is pushed to the right to the fourth position, the control module 2 can control the mobile terminal to switch to the next song.

[0065] Specifically, when the mobile terminal is playing music, taking controlling the volume of the mobile terminal as an example, when the tongue-controlled push rod 62 is pushed upward to the first position, the control module 2 can control the volume of the mobile terminal through the wireless communication module 3 to turn up the volume of the mobile terminal.

[0066] It is worth mentioning that the volume adjustment control of the mobile terminal is also applicable to playing audio and video and voice messages.

[0067] In this embodiment, the principle and process of the control module 2 correspondingly controlling the multimedia playing state of the mobile terminal by the movement of the tongue-controlled push rod 62 are prior arts, and will not be elaborated herein.

[0068] Furthermore, the control of the multimedia playback state of the mobile terminal also includes: fast forward and fast rewind. When the tongue-controlled push rod 62 is moved to the left to the third position and remains at the third position for a threshold time, the control module 2 can control the mobile terminal to fast forward; when the tongue-controlled push rod 62 is moved to the right to the fourth position and remains at the fourth position for a threshold time, the control module 2 can control the mobile terminal to fast rewind.

[0069] Specifically, the threshold time for maintaining the third position and the fourth position is set in the control module 2, and the set time is preferably 3 seconds.

[0070] Furthermore, a second soft sheath 63 is sleeved on the tongue control push rod 62. The second soft sheath 63 can prevent the hard surface of the tongue control push rod 62 from contacting the mouth and tongue of the wearer, thereby better protecting the wearer and ensuring safety and hygiene.

[0071] Exemplarily, the material of the second soft sheath 63 is set to be silicone.

[0072] In this embodiment, the smart helmet further includes a power supply (not shown) and a chin button 7. The power supply is disposed in the helmet body 1. The chin button 7 can be pressed and disposed in the helmet body 1 and is communicatively connected with the control module 2. The chin of the wearer of the helmet body 1 can press the chin button 7 to enable the power supply to the control module 2 or cut off the power supply to the control module 2.

[0073] Specifically, the wearer's lower jaw presses the lower jaw button 7 downward for 3 seconds to enable the power supply to the control module 2, or cuts off the power supply to the control module 2. Specifically, the lower jaw button 7 is correspondingly arranged below the wearer's lower jaw. When the smart helmet is in a power-on state, the wearer's lower jaw presses the lower jaw button 7 downward for 3 seconds to cut off the power supply of the smart helmet, that is, the smart helmet is turned off; when the smart helmet is in a power-off state, the wearer's lower jaw presses the lower jaw button 7 downward for 3 seconds to enable the power supply of the smart helmet, that is, the smart helmet is turned on.

[0074] In this embodiment, the principle and process of realizing power on and off control by buttons are prior art and will not be elaborated herein.

[0075] Furthermore, a third soft sheath 71 is provided on the jaw button 7. The provision of the third soft sheath 71 can prevent the hard surface of the jaw button 7 from making hard contact with the jaw part of the wearer, thereby better protecting the wearer.

[0076] Exemplarily, the material of the third soft sheath 71 is set to be silicone.
