[0040] The alloy support is made of aluminum-magnesium alloy material and has reinforcing ribs and heat dissipation channels to enhance overall rigidity and reduce heat accumulation.

[0041] The multilayer shockproof buffer structure is arranged between the LED digital tube body and the alloy support and includes a high-elasticity silica gel layer for improving the buffering capacity, an energy-absorbing foam layer with an open-hole structure to disperse impact force, and a shock-absorbing rubber layer provided with a grid-shaped exhaust groove to provide stable support after deformation under stress.

[0043] The fixing assembly includes high-strength bolts for connecting the alloy support and the LED digital tube body and anti-loosening washers for improving the structural stability and preventing loosening caused by long-term vibration.

[0044] Embodiment 1

[0045] In this embodiment, aluminum-magnesium alloy is used as the support (2) of the LED digital tube. The alloy material has high strength and corrosion resistance, which can effectively prevent deformation caused by external force. To enhance the bending resistance, multidirectional reinforcing ribs (21) are designed on the surface of the support to improve the stress uniformity by reasonably distributing the support points. Meanwhile, heat dissipation channels (22) are designed on the support to help quickly reduce the working temperature of the LED digital tube and avoid temperature rise caused by long-time operation.

[0046] In the bending resistance test, a standard test equipment is used to apply an external force of 50 N to the middle of the support and measure the deformation. The deformation of the traditional aluminum support is 2 mm, while the deformation of the support of this patent is only 0.1 mm, and the bending resistance is improved by 20 times. In addition, in the 96-hour salt spray test, the surface of the traditional aluminum support shows obvious corrosion, while the surface of the support of this patent has no obvious corrosion, and the weather resistance is obviously better than that of the prior art, and it is suitable for harsh environments such as high humidity and salt spray.

[0047] Embodiment 2

[0048] To improve the shock resistance of the LED digital tube, a multilayer shockproof buffer structure (3) is installed between the LED digital tube body (1) and the alloy support (2) in this embodiment, including a high-elasticity silica gel layer (31), an energy-absorbing foam layer (32), and a shock-absorbing rubber layer (33). Among them, the high-elasticity silica gel layer mainly plays a buffering role and can quickly absorb and disperse external impact force; the energy-absorbing foam layer has an open-hole structure and can effectively disperse vibration; and the shock-absorbing rubber layer is designed with a grid-shaped exhaust groove to provide stable support after deformation under stress.

[0049] In the vibration experiment, the LED digital tube with and without shock-absorbing buffer structure is tested, the 50Hz vibration environment is simulated, and the amplitude change is measured. The amplitude of the LED digital tube without shock-absorbing buffer structure is 3.5mm, and the amplitude of the LED digital tube with the shock-absorbing buffer structure is reduced to 0.3mm, and the anti-vibration ability is increased by 90%. In addition, in the 1-meter height free fall impact test, the damage rate of the LED digital tube without shock-absorbing structure is 60%, and the damage rate of the LED digital tube with the shock-absorbing structure is only 5%, effectively improving the impact resistance of the LED digital tube.

The traditional rigid PCB board has a rupture rate of 80% during the test, while the flexible PCB board of the present application does not rupture under the same test conditions, showing excellent bending resistance. In addition, in the 1.5-meter free fall impact test, the damage rate of the traditional rigid PCB board is 80%, while the damage rate of the present application is only 5%, and the impact resistance is increased by 16 times.

Among them, the high-strength bolts are made of stainless steel or titanium alloy, which can adapt to harsh outdoor environments and are not easy to rust or break; the lock washer adopts a double-spring washer structure, which can keep stable and tight in a continuous vibration environment.

[0055] In the vibration durability test, the long-term vibration environment on the highway traffic sign is simulated, and the fastening state of the fixing component is measured. The traditional single-layer nut has a loosening rate of 50% after a long time of vibration, while the present application has no loosening phenomenon under the same environment, showing excellent stability and vibration resistance.
