[0033] Embodiment 1:

[0034] The present embodiment provides a mine safety helmet, which is applied to working scenes in mines and worn by mine workers to provide head protection for mine workers when working underground. At the same time, the mine safety helmet in the present embodiment is provided with an assembly seat 30 on the main body of the safety helmet 10, and an external matching block 20 is used to realize the assembly of positioning, emergency alarm and footlight 23. While ensuring the original function of the mine safety helmet, its functionality is improved, the survival rate of mine workers after an accident is increased, and the difficulty of rescue is reduced. By assembling the external matching block 20 on the safety helmet, its contact with the environment inside the mine can be reduced, the probability of corrosion is reduced, its service life is increased, and the cost of replacing equipment for enterprises is reduced.

[0035] For details, please refer to Figure 1-4 The mine safety helmet includes a helmet body 10 and an external matching block 20, wherein, in terms of function, the helmet body 10 plays the most basic protective role of the mine safety helmet, specifically plays the role of protecting the head, avoiding or reducing casualties caused by external physical impact on the wearer. In this embodiment, the helmet body 10 also plays the role of assembly support, and the external matching block 20 is assembled on the helmet body 10, which is portable and easy to wear. The external matching block 20 is used to provide positioning, lighting, alarm and other protective functions, and the internal part thereof can achieve the functions of positioning, lighting, and rapid emergency alarm by adjusting the built-in components.

[0036] In terms of structure, see Figure 1-4 , a brim 11 is provided at the front end of the helmet body 10, and the brim 11 can also play a certain protective role, for example, to prevent falling objects from accidentally injuring the face. An assembly seat 30 is provided on the brim 11, and the assembly seat 30 is mainly used to assemble the external matching block 20, and at the same time plays a role of containment and sealing. Specifically, the lower end of the assembly seat 30 is open, and a cavity for assembling the external matching block 20 is provided in the assembly seat 30. Relatively speaking, the external matching block 20 can be detachably assembled in the assembly seat 30, and the detachable assembly method can be achieved by means of a buckle 27, magnetic attraction, pasting, etc. This design enables the external matching block 20 to be quickly and conveniently taken out, and the internal functional module can be taken out for charging or replacement when outside the mine. At the same time, in a mine environment, in an emergency, the external matching block 20 can be taken out to make a handheld lighting device, thereby improving its functionality.

[0037] For external module 20, please refer to Figure 1-5 The external block 20 includes a positioning module 21, a smart button 22, a foot light 23, a power supply and a shell 24, wherein the shell 24 is used as a shell, and a buckle 27 or other connectors can be set on the outside of the shell 24 to realize the firm assembly of the external block 20 on the helmet body 10. At the same time, the positioning module 21, the smart button 22, the foot light 23, and the power supply are all installed in the shell 24, and the shell 24 plays a role in protecting the internal components. The positioning module 21 is mainly used to send positioning signals, so that when an accident occurs, external rescuers can accurately know the location of the trapped person through the positioning module 21, reducing the difficulty of rescue. The smart button 22 is used to control the internal functions of the external block 20. For example, the mine workers can control the switch of the foot light 23 and trigger the alarm module 25 through the smart button 22. The foot light 23 is used as a light source to illuminate the soles of the feet. Specifically, the positioning module 21, the smart button 22, and the foot light 23 are all electrically connected to the power supply to achieve power supply. The front of the assembly seat 30 of the safety helmet body 10 is respectively provided with air avoidance holes 31 corresponding to the smart button 22 and the foot light 23, so that the miners can press or guide the light source through the air avoidance holes 31.

[0038] For more details, see Figure 3-5 The external configuration block 20 also includes a circuit board, an alarm module 25 and a control chip 26 disposed on the circuit board, wherein the circuit board is used to assemble various electronic components and realize the connection between various electronic components. Specifically, the smart button 22, the foot light 23, the positioning module 21, the alarm module 25 and the power supply are directly or indirectly disposed on the circuit board, and are electrically connected to the control chip 26 through the circuit board. Each component realizes the control of the corresponding function by interacting with the control chip 26 signal. For example, the control chip 26 receives the input of the smart button and outputs the corresponding driving signal to control the foot light 23 to turn on and off and trigger the buzzer of the alarm module 25.

[0039] For detailed settings of each component, please refer to Figure 5, the smart button 22 is used to send the switch signal and alarm signal of the foot light 23 to the control chip 26 according to the number of times pressed per unit time. The smart button can be a mechanical switch button. The control chip 26 receives the number of times pressed by the mine worker to determine the output corresponding drive signal. For example, within 3 seconds, the button is pressed once to turn on / off the foot light 23. Within 3 seconds, it is pressed twice continuously to turn on the buzzer function of the alarm module 25, ensuring that its operation is simple and effective enough without complicated operations. In the second aspect, as a preferred embodiment, the positioning module 21 adopts one or more of the GPS (Global Positioning System) positioning module, the local wireless positioning module and the UWB (Ultra Wide Band) positioning module. Of course, the positioning module 21 can also be realized by other positioning technologies or positioning modules that can achieve accurate positioning in the mine. Among them, the positioning module 21 can be turned on in real time when the mine worker enters the mine, and it provides positioning information in real time by sending a positioning signal. Of course, after the mine worker presses the smart button 22, the positioning position can be retained and calibrated. Also preferably, the alarm module 25 includes a buzzer.

[0040] As a preference, see Figure 4 The top and front of the external block 20 are respectively provided with buckles 27, and the assembly seat 30 is provided with a slot adapted to the buckle 27, and the external block 20 is connected to the assembly seat 30 buckle 27 through the cooperation of the slot and the buckle 27. Specifically, the module of the buckle 27 is provided with an undercut, and the external block 20 is buckled on the assembly seat 30 through the undercut.

[0041] Preferably, see Figure 4 , the assembly seat 30 is fixedly connected to the helmet body 10 near one side of the helmet body 10. Further preferably, the assembly seat 30 and the helmet body 10 are integrally formed to ensure the stability of the assembly seat 30. Also preferably, a cover plate 32 is provided at the opening position of the assembly seat 30. The cover plate 32 is used to cover the assembly seat 30 after the external matching block 20 is placed in the assembly seat 30, so that the inside of the assembly seat 30 is sealed to prevent the external water vapor from corroding the internal external matching block 20. More specifically, the cover plate 32 is rotatably buckled and connected at the opening, and the cover plate 32 can be buckled on the helmet body 10 through a locking member. At the same time, a sealing gasket 321 adapted to the outer periphery of the opening is provided on one side of the cover plate 32 to ensure the sealing inside the assembly seat.

[0042] In addition, the mine safety helmet of this embodiment further comprises a mine lamp fastener 40, which is mounted on the top of the assembly seat. The mine lamp fastener 40 is used to assemble a mine lamp so that the mine lamp can be mounted on the mine safety helmet.
