[0030] The first device module 41 and the second device module 42 have a card slot 403 and a probe 404. The card slot 403 is provided with a flexible circuit board 8. The flexible circuit board 8 is placed under the probe 404 and connected to the probe 404. The control circuit of the signal processing and power data in the device module is connected to the probe of the external device through the probe 404 to conduct power, signals and data.

[0031] The flexible circuit board 8 has a retractable rubber part 81, which is fixed to the left arc-shaped guide rail structure component 1 and the right arc-shaped guide rail structure component 2, and is attached with Velcro.

The rear-mounted structural component 3 is provided with size positions 34 corresponding to different sizes. The concave socket 5 and the connection groove 31 are connected with adjustable screws 35 and washers 36. By adjusting the position of the size position 34 and the tightness of the screw 35, it can be compatible with helmets of different sizes. The washer 36 increases the contact surface between the screw 35 and the concave socket 5 and the connection groove 31, making them more closely connected. The rear-mounted structural component 3 is provided with a buckle 37, which passes through the rear-mounted structural component to fix the wires of the external device, so that the external wires are neatly concentrated and the risk of connection obstacles is reduced.

[0046] By integrating the power supply as the power supply system and using the communication protocol to transmit data, the power supply data and information of the equipment are accurately collected. The power supply source of all equipment is provided by the integrated power supply of the power supply system in a unified point-to-point manner. The equipment does not need to be connected to additional batteries and external connection cables, reducing the risk of connection obstacles. At the same time, the use of a single source power supply does not require the installation of multiple types of batteries for each device, effectively simplifying the rail space, providing more space for the installation of helmet external devices, and effectively reducing the fatigue caused by the installation of multiple types of batteries for long-term helmet wearers. The compatibility design of the rear adjustment structure adapts to various helmet sizes.
