[0022] This specific embodiment is a power supply box with a protective structure, such as... Figures 1-6 As shown, the power supply box with a protective structure includes a box body 1 and a top cover 2. Arc-shaped grooves are provided at the four corners of the box body 1, and rubber pillars 3 are fixed at the four corners of the top cover 2. The rubber pillars 3 cooperate with the arc-shaped grooves. Two movable cavities 4 are opened opposite each other inside the rubber pillars 3. A circular hole is provided on one side of the inner wall of the movable cavity 4, penetrating one end of the rubber pillar 3. A piston rod 5 is movably installed inside the circular hole. A damping block 7 is fixed to the inner end of the piston rod 5. A damping plate 9 is provided on the inner wall of the movable cavity 4, cooperating with the damping block 7. A first spring 8 is connected between the side of the damping block 7 away from the piston rod 5 and the inner wall of the movable cavity 4. A rubber block 6 is fixed to the end of the piston rod 5 away from the damping block 7. A top buffer assembly is provided on the side of the top cover 2 away from the box body 1, and a bottom buffer assembly is provided at the bottom of the box body 1.

[0023] Through the interaction of rubber block 6 and rubber column 3, the movement of piston rod 5 and circular hole, combined with the interaction of damping block 7 and damping plate 9, and the elastic effect of first spring 8, the buffering effect on box 1 is effectively improved. At the same time, with the interaction of top buffer assembly and bottom buffer assembly, the sides of box 1 are further buffered. This solves the problem that in the prior art, only the four corners of the power box are buffered and protected by buffer blocks, and the position of the mounting cover cannot play a buffering and protection role, resulting in poor performance. It also solves the problem that the mounting cover in the prior art is relatively thin, and when the power box is dropped, the mounting cover is prone to breakage and damage, which affects the subsequent protection effect on the internal control module.

[0024] The top buffer assembly includes an arc-shaped rubber plate 10 and a second spring 11. Several arc-shaped rubber plates 10 are arranged on one side of the top cover 2, and the second spring 11 is connected between the arc-shaped concave surface of the arc-shaped rubber plate 10 and the top cover 2. A telescopic rod is provided on the inner side of the second spring 11. The two ends of the telescopic rod are fixedly connected to the arc-shaped rubber plate 10 and the top cover 2 respectively. The telescopic rod effectively ensures the stability and performance of the arc-shaped rubber plate 10 and the second spring 11.

[0025] The bottom buffering assembly comprises first buffering rods 12, a second buffering rod 13 and a third spring 14, the first buffering rods 12 are hingedly connected to the bottom of the box body 1, the second buffering rod 13 is hingedly connected to the first buffering rods 12, the third spring 14 is fixedly connected to one end of the second buffering rod 13 away from the first buffering rods 12, and the other end of the third spring 14 away from the second buffering rod 13 is connected to the bottom of the box body 1.

[0026] Two connecting plates 15 are fixed to the outer wall of the rubber column 3, the connecting plates 15 are matched with the outer wall of the box body 1, the outer wall of the box body 1 is provided with a plurality of positioning holes, the connecting plates 15 are provided with a plurality of locking bolts 16, the locking bolts 16 are threadedly matched with the positioning holes, the connecting plates 15 and the box body 1 are fixedly connected together through the locking bolts 16, and then the rubber column 3 and the top cover 2 are fixed.

[0027] Embodiment:

[0028] In use, first, the top cover 2 is adjusted to press on the upper port of the box body 1, and a plurality of rubber columns 3 are inserted into the arc-shaped grooves in the corresponding positions of the box body 1, when the top cover 2 abuts against the opening end of the box body 1, the connecting plates 15 are matched with the outer wall of the box body 1 under the action of the rubber columns 3, at this time, the locking bolts 16 are aligned with the positioning holes in the corresponding positions of the box body 1, then the plurality of locking bolts 16 are tightened one by one, so that the connecting plates 15 and the outer wall of the box body 1 are fixedly connected together, and then the top cover 2 is fixed at the upper port of the box body 1;

[0029] When the box body 1 falls, the rubber blocks 6 in contact with the ground are extruded, and then the corresponding piston rods 5 are extruded into the movable cavities 4, under the cooperation of the damping blocks 7 and the damping pieces 9 and the elastic action of the first springs 8, the impact and bumping of the box body 1 are effectively buffered;

[0030] When one side of the top cover 2 faces the ground, the arc-shaped rubber plate 10 is compressed, which in turn compresses the second spring 11. The resilience of the arc-shaped rubber plate 10, combined with the elasticity of the second spring 11, effectively cushions one side of the top cover 2. Simultaneously, when the bottom of the box 1 faces the ground, the second buffer rod 13 is compressed. Due to the hinged connections between the two ends of the first buffer rod 12 and the box 1 and the second buffer rod 13 respectively, the movable end of the second buffer rod 13 is compressed towards the box 1, further compressing the third spring 14 and providing additional cushioning at the bottom of the box 1. This design effectively improves the protection of the power box 1, solving the problem of existing technologies that only use buffer blocks to buffer and protect the four corners of the power box, leaving the mounting cover ineffective and resulting in poor performance. It also addresses the issue of existing mounting covers being too thin, easily breaking or damaging when the power box is dropped, thus affecting the protection of the internal control modules. This design ensures the protective performance of the power box during use, thereby improving the protection of the internal control modules and extending the lifespan of the power box and its internal control modules.

[0031] It should be further noted that the installation structure, connection method or setting method of each component in this utility model are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.

[0032] All technical features in this embodiment can be freely combined according to actual needs.
