Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of display devices, in particular to a pressure head-up display device with modular wireless voice. Background Art
[0002] During firefighting and rescue, positive pressure firefighting air breathing apparatus will be worn, including compressed air cylinders, air tubes, and air respiration masks.
[0003] The pressure head-up display is a crucial feature of fire masks. It uses an electronic pressure gauge sensor to collect the gas pressure within the cylinder and wirelessly transmits the signal to a head-up display (HUD) installed within the mask. The display features three indicator lights: green, yellow, and red. A green light indicates the cylinder pressure is between (30-10) MPa, while a yellow light indicates the cylinder pressure is between (10-6) MPa. When the cylinder pressure is below 6 MPa, the red light flashes rapidly. These indicators indicate safety, warning, and alarm pressure zones within the cylinder, respectively. Without looking at the pressure gauge, users can clearly see the approximate pressure range of the remaining gas in the cylinder, eliminating the need to use their hands to flip through the gauge, completely freeing their hands.
[0004] When wearing a protective mask, the mask blocks the wearer from speaking while isolating the outside air from the wearer. This results in people around and the wearer's walkie-talkie being unable to hear the wearer's voice. In the event of an emergency, effective communication is impossible, resulting in serious safety accidents. Utility Model Content
[0005] To solve the above problems, the utility model proposes a pressure head-up display device with modular wireless voice. The device integrates a modular wireless voice device, which can not only display the air pressure but also solve the problem of the mask wearer's voice being blocked.

[0007] A pressure head-up display device with modular wireless voice, characterized by comprising:
[0008] Pressure head-up display equipment;
[0009] A wireless voice device is connected to the pressure head-up display device, and the wireless voice device is electrically connected to the pressure head-up display device so that the wireless voice device is powered by the pressure head-up display device.
[0010] The pressure head-up display device has a mounting structure, one side of the mounting structure has a flat mounting wall, and the wireless voice device is attached and mounted on the mounting wall of the mounting structure.
[0011] The installation wall is facing the face side.
[0012] The main body of the wireless voice device is a plate-shaped structure.
[0013] The pressure head-up display device and the wireless voice device both have a magnetic attraction structure, and the pressure head-up display device and the wireless voice device are connected by magnetic attraction.
[0014] A first positioning groove is formed on the mounting wall, wherein the first positioning groove has a female magnetic connector or a male magnetic connector;
[0015] The wireless voice device has a first boss on the side that interfaces with the mounting wall, and the first boss has the other of a female magnetic connector or a male magnetic connector;
[0016] When the wireless audio device is installed on the installation wall, the first boss is embedded in the first positioning groove, and the female head of the magnetic connector is electrically connected to the male head of the magnetic connector.
[0017] The cross sections of the first positioning groove and the first boss are non-circular.
[0018] The installation wall is provided with a second positioning groove or a second boss;
[0019] The wireless audio device is provided with a second positioning groove or a second boss on one side of the mounting wall;
[0020] When the wireless audio device is installed on the installation wall, the second boss is embedded in the second positioning groove.
[0021] The beneficial effects of using the utility model are:

[0029] In order to make the purpose, technical solution and advantages of this technical solution more clear, the following technical solution is further described in detail in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of this technical solution.
[0030] In order to solve the problem in the prior art that after wearing a protective mask, the mask isolates the outside polluted air and also blocks the wearer from speaking, Figure 1 As shown, this embodiment proposes a pressure head-up display device with modular wireless voice. The device consists of two main devices, namely a pressure head-up display device 10 and a wireless voice device 20.
[0031] like Figure 2 As shown, the pressure head-up display device 10 is mainly composed of an inverted "U"-shaped bracket. The left side of the "U"-shaped bracket is the electrical equipment related to the pressure head-up display, and the right side of the "U"-shaped bracket is the mounting structure 11. In this embodiment, the interior of the mounting structure 11 mainly contains a battery, which supplies power to the electrical equipment related to the pressure head-up display on the left side through the circuit inside the "U"-shaped bracket. The side of the mounting structure 11 facing the user's face is the inner side, which is flat. The main body of the mounting structure 11 is also a plate-like structure. A runway-shaped first positioning groove is opened in the middle of the inner surface of the mounting structure 11. The first positioning groove contains a magnetic connector female 13. The magnetic connector female 13 is slightly raised at the bottom surface of the first positioning groove. At the same time, a circular second positioning groove 14 is opened at the bottom of the inner surface of the mounting structure 11.
[0032] like Figure 3 As shown, the main body of the wireless audio device 20, excluding the microphone, is also a flat plate-shaped structure. A first boss 21 is provided in the middle of one main extension surface of the wireless audio device 20. A groove is provided on the end face of the first boss 21, within which a male magnetic connector 22 is located. A circular second boss 23 is also provided below the surface of the wireless audio device 20 where the first boss 21 is located.
[0033] like Figure 1As shown, when the wireless audio device 20 is installed inside the mounting structure 11 of the pressure head-up display device 10, the overall thickness of the pressure head-up display device 10 and the wireless audio device 20 is relatively small. The first boss 21 is embedded in the first positioning groove 12, and the second boss 23 is embedded in the second positioning groove 14. At this point, the male magnetic connector 22 is electrically connected to the female magnetic connector 13, and the wireless audio device 20 draws power from the battery built into the pressure head-up display device 10. The pressure head-up display device 10 includes a built-in battery, a wireless receiving module, and a pressure indicator light for displaying the cylinder pressure. The wireless audio device 20 includes a built-in wireless transmitting module and a microphone for collecting sound and transmitting it to a loudspeaker or intercom.
[0034] Compared to powering the pressure head-up display device 10 and the wireless audio device 20 separately, the wearer no longer needs to manage the power of two separate devices. This also saves mask space. Compared to integrating the wireless audio device 20 into a traditional pressure head-up display, users have more flexible configuration options.
[0035] Since magnetic attachment is the most convenient way to install and remove the wireless audio device 20 and the pressure head-up display device 10, a magnetic attachment connection is adopted. In other embodiments, the connection methods of the wireless audio device 20 and the pressure head-up display device 10 include but are not limited to fixing the wireless audio device 20 to the pressure head-up display device 10 with a snap or screw, or connecting the pressure head-up display device 10 and the wireless audio device 20 with a snap.
[0036] In addition, it should be noted that the wireless audio device 20 can also obtain power from the pressure head-up display device 10 through a connector, wiring, and jack to form power supply.
[0037] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scope based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
