A displacement sensor 32 is provided inside the device box 31, and a buzzer 33 is provided on the side of the displacement sensor 32. A control board 34 that is electrically connected to the displacement sensor 32 and the buzzer 33 is fixedly connected to the inner wall of the device box 31.

[0026] In operation, the displacement sensor 32 of OMEGA LD320 model installed inside the equipment box 31 is kept in vertical distance with the H-shaped support 21 on the bottom surface of the anti-expansion box 1, when the anti-expansion box 1 is displaced, the displacement sensor 32 collects displacement data in real time and transmits to the control board 34, wherein the control board 34 integrates STM32F103C8T6 microcontroller as the main control chip, the built-in ADC module collects the signal of the displacement sensor 32, the external SIM800C GSM module realizes the short message alarm, the buzzer 33 is triggered through the GPIO port control, the whole satisfies the vehicle power supply 12-24VDC power supply and EMC anti-interference requirements, the preset displacement threshold trigger mechanism in the control board 34 controls the buzzer 33 of TDK PS1740P02BT model to issue sound and light alarm, at the same time, the alarm signal is sent to the driver's mobile phone or vehicle terminal through the integrated wireless signal module, realizing real-time monitoring and early warning of the displacement state of the anti-expansion box 1.

[0027] Further, the mounting assembly 2 comprises the H-shaped support 21 fixedly connected to the bottom surface of the anti-expansion box 1, the H-shaped support 21 is provided with the connecting block 22 on the bottom surface, the connecting block 22 is fixedly connected with the vehicle frame 4, the H-shaped support 21 and the connecting block 22 are coaxially provided with the limiting hole penetrating through the side surface, the limiting rod 23 is inserted into the limiting hole, and the threaded holes are formed at both ends of the limiting rod 23 and locked by the bolts 24.

[0028] In operation, after the bottom surface of the H-shaped support 21 abuts against the top surface of the connecting block 22, the operator aligns the limiting holes on the side surfaces of the H-shaped support 21 and the connecting block 22 coaxially, inserts the limiting rod 23 and rotates the bolts 24 at both ends to lock and fix, the elastic washers and double nut locking assemblies at the ends of the bolts 24 prevent the bolts 24 from loosening due to vibration; when disassembling, the bolts 24 are operated in reverse and the limiting rod 23 is pulled out, so that the anti-expansion box 1 and the vehicle frame 4 can be quickly separated, and the replacement or maintenance of the anti-expansion box 1 can be completed.

[0029] Further, the control board 34 integrates the wireless signal module, and the wireless signal module is configured to send an alarm signal to the driver's terminal when the displacement sensor 32 detects the displacement of the anti-expansion box 1.

[0030] In operation, the control board 34 integrates the wireless signal module, and the wireless signal module is configured to send an alarm signal to the driver's terminal when the displacement sensor 32 detects the displacement of the anti-expansion box 1.

[0031] Further, the end of the bolt 24 is provided with a loosening prevention structure, which includes an elastic washer sleeved on the end of the bolt 24 and a double-nut locking assembly threadedly connected with the bolt 24;

[0032] In operation, the loosening prevention structure at the end of the bolt 24 is composed of the elastic washer sleeved on the end of the screw rod of the bolt 24 and the double-nut locking assembly screwed on the screw rod. In installation, the elastic washer is first sleeved on the end of the screw rod and abuts against the end face of the limiting rod 23, and then the two nuts are screwed in turn and locked by applying reverse torque to the two nuts by a wrench. This embodiment effectively prevents the bolt 24 from rotating and loosening due to vibration during vehicle driving by the deformation buffer of the elastic washer and the mutual locking friction of the double nuts, thereby ensuring the connection stability between the limiting rod 23 and the H-shaped support 21 and the connecting block 22 and reducing the installation failure of the anti-expansion box 1 caused by the falling of the bolt 24.

[0033] Further, the control board 34 is configured to synchronously trigger the alarm instructions of the buzzer 33 and the wireless signal module when the displacement detected by the displacement sensor 32 exceeds the preset threshold value;

[0034] In operation, the threshold comparator built in the control board 34 compares the displacement detected by the displacement sensor 32 with the preset threshold value in real time. When the displacement exceeds the threshold value, the control board 34 synchronously sends the audible and light alarm instructions to the buzzer 33 and sends the data transmission instructions to the wireless signal module, triggering the buzzer 33 to emit high-frequency alarm sound in the equipment box 31, and the wireless signal module sends the alarm information containing the displacement data to the terminal. This embodiment forms a three-dimensional early warning network by the on-site alarm of the buzzer 33 and the remote alarm of the wireless signal module through the double response mechanism of the control board 34 to the displacement data, ensuring that the driver can timely know the abnormal state of the anti-expansion box 1 whether in the vehicle or outside the vehicle, avoiding the delay of maintenance caused by single alarm failure, and greatly reducing the probability of the anti-expansion box 1 falling off.

[0035] Working principle: The anti-expansion box 1 is rigidly connected with the vehicle frame 4 through the rectangular array distributed mounting assemblies 2 on the bottom surface, the H-shaped support 21 of the mounting assembly 2 is transversely limited by the limiting rod 23 penetrating the coaxial limiting holes of the H-shaped support 21 and the connecting block 22 on the top surface, and the axial locking and fixing are completed by the bolt 24 screwed into the threaded holes at both ends of the limiting rod 23; the anti-falling assembly 3 is fixed to the top surface of the connecting block 22 through the equipment box 31, and the displacement sensor 32 inside the anti-falling assembly 3 monitors the relative displacement between the anti-expansion box 1 and the connecting block 22 in real time. When the displacement exceeds the preset threshold value of the control board 34, the control board 34 synchronously drives the buzzer 33 to emit audible and light alarm and triggers the wireless signal module to send the displacement alarm signal to the driver terminal; during vehicle maintenance, the locking of the H-shaped support 21 and the connecting block 22 can be released by dismounting the bolt 24 and pulling out the limiting rod 23, realizing the quick dismounting and replacement of the anti-expansion box 1.
