[0029] Example:

[0030] like Figure 1-4As shown, the utility model provides an intelligent external plug-in device for a safety helmet, comprising a shell 100 and a movable shell 200, wherein the shell 100 is U-shaped, matching the shape of the front of the safety helmet body 300, so that the external plug-in device can be easily installed on the safety helmet body 300; the shell 100 is provided with assembly holes 103 at both free ends near the shell 100, and the safety helmet body 300 is provided with mounting holes corresponding to the assembly holes 103, and the pin passes through the assembly hole 103 and the mounting hole corresponding to the assembly hole 103 and is engaged with the lining inside the safety helmet body 300, so that the external plug-in device can be easily disassembled and assembled, and is easy to repair and replace.

[0031] A notch 104 is provided on the shell 100, and the notch 104 is provided in the middle front part of the shell 100, that is, on the side away from the helmet body 300, so that the LED light and the camera in the movable shell 200 can face the front of the wearer, which is convenient for the wearer to use; the movable shell 200 is accommodated in the notch 104, and the movable shell 200 is rotatably connected to the shell 100 through a rotating connection device, and the rotating connection device is a hinge shaft. Since the movable shell 200 is rotatably connected to the shell 100, the wearer can rotate the movable shell 200 relative to the shell 100 by applying external force, adjust the working angle of the LED light and the camera, and make the LED light and the camera of the movable shell 200 face the direction required by the wearer.

[0032] The outer sides of the two free ends of the housing 100 are each provided with a switch 101 and two function buttons 102, so that the wearer can conveniently use his left or right hand to turn on or off the external device.

[0033] The shell 100 has a first cavity, which accommodates a circuit board, two batteries and a controller integrated on the circuit board. The two batteries are respectively located at the two free ends of the shell 100. By arranging batteries in the two free ends of the shell 100, not only can the service life of the external device be improved, but also the balance of the two ends of the external device can be maintained when the external device is installed on the helmet body 300.

[0034] The movable shell 200 has a second cavity, which accommodates an LED light, a camera, a speaker and a microphone. The controller is connected to the LED light, the camera, the speaker and the microphone through the function buttons 102, and the battery is connected to the controller through the switch 101.

[0035] The ends of the two free ends of the shell 100 are both provided with warning lights 105, and the warning lights 105 are connected to the controller. Since the ends of the free ends of the shell 100 are facing the rear of the wearer, the warning lights 105 can effectively remind other people or vehicles in the rear to pay attention, thereby improving the practical effectiveness and wearing safety of the helmet.

[0036] The bottom of the movable housing 200 is provided at a through hole corresponding to the microphone, so that the content of the wearer's conversation is better transmitted to the microphone.

[0037] A hazardous gas concentration sensor is also provided in the housing 100, which is connected to the controller. When the environmental information read by the hazardous gas concentration sensor is different from the preset value, the controller issues an environmental abnormality alarm through the speaker to remind the wearer that the current environment is dangerous and that he needs to leave or seek rescue immediately.

[0038] The utility model also provides a safety helmet, comprising the above-mentioned safety helmet intelligent external hanging device.

[0039] In summary, the present invention solves the deficiencies in the prior art through the above-mentioned structural design, and has the characteristics of reasonable design, high safety, and good comfort.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
