Detailed Description

The technical scheme of the utility model is further explained by combining the attached drawings.

As shown in fig. 1, the present invention includes: 1. the device comprises a device terminal panel, 2, a device vehicle mounting bolt hole, 3, a camera monitoring lens, 4, an alarm (on, busy) indicator lamp, 5, an alarm trigger module, 6, a striker button, 7, an angle limit and device switch module, 8, a device terminal rear cover, 9, an alarm button, 10, a loudspeaker, 11 and a microphone.

The equipment terminal panel and the rear cover form a shell, components such as a monitoring lens 3, an indicator lamp 4, an alarm key 9 and a loudspeaker 10 are all installed inside the shell, an opening matched with each component is formed in the terminal panel, and the monitoring lens 3, the indicator lamp 4 and the alarm key 9 are embedded into the opening.

As shown in fig. 2 and 3, the angle limiting and device switching module includes a fixed end and a shaft, and the alarm triggering module can rotate around the shaft and cover the lens or the alarm button. The alarm triggering module 5 is rotated upwards around the angle limiting and equipment switch module in the axial direction, so that the end part of the alarm triggering module covers the lens 3, and the lens 3 is protected; the alarm triggering module 5 is rotated downwards around the shaft, so that the end part of the alarm triggering module is covered on the alarm key 9, and the positions of the module firing pin key and the alarm key are superposed.
