When the movable block moves back upward, the rotating plate rotates until the through hole corresponds to the second through slot on the fixed plate, so that the air return is blocked by the rotating plate and the flow rate slows down, so that the movable block continuously consumes the power accumulated in the first spring when moving back upward, thereby playing a shock-absorbing role on the first spring, so that the bottom plate can move back smoothly to protect the equipment; 4) During operation, when the movable block moves downward, the transverse piston moves toward the exhaust hole, so that the conductive rod cuts the magnetic flux lines to generate current and passes into the electromagnet, so that the electromagnet generates an attractive force on the magnetic block, ensuring that the first through slot corresponds to the second through slot, so that air can smoothly enter the fixed box to ensure the buffering effect. When the movable block moves back, the conductive rod moves in the opposite direction, so that the electromagnet generates a repulsive force on the magnetic block, thereby driving the rotating plate to rotate to the corresponding position of the through hole and the second through slot, so as to facilitate the smooth return of the bottom plate.

When the electromagnet 3077 generates a repulsive force on the magnetic block 3076, the guide plate 3074 contacts the limit plate on the other side, so that the second through slot 30713 corresponds to the through hole 30711.

When the movable block 302 moves back upward, the rotating plate 3078 rotates to the through hole 30711 corresponding to the second through slot 30713 on the fixed plate 30712, so that the air return is hindered by the rotating plate 3078 and the flow rate becomes slower, so that the movable block 302 continuously consumes the power accumulated in the first spring 304 when moving back upward, thereby having a shock-absorbing effect on the first spring 304, so that the bottom plate 1 can move back smoothly to protect the equipment.

[0024] The magnet control unit 308 includes a transverse air box 3081 fixedly installed on one side of the fixed box 301, the transverse air box 3081 is connected to the fixed box 301 below the movable block 302, an exhaust hole 3082 is provided at the end of the transverse air box 3081, a transverse piston 3083 is movably installed inside the transverse air box 3081, the outer wall of the transverse piston 3083 is tightly attached to the inner wall of the transverse air box 3081, a conductive rod 3084 is installed on one side of the transverse piston 3083, and the inner walls on both sides of the transverse air box 3081 are provided with conductive rods 3084.

When the movable block 302 moves downward, the transverse piston 3083 moves toward the exhaust hole 3082, so that the conductive rod 3084 cuts the magnetic flux line to generate current and passes into the electromagnet 3077, so that the electromagnet 3077 generates an attractive force on the magnetic block 3076, ensuring that the first through slot 30710 corresponds to the second through slot 30713, so that air can smoothly enter the fixed box 301, and ensure the buffering effect. When the movable block 302 moves back, the conductive rod 3084 moves in the opposite direction, so that the electromagnet 3077 The magnetic block 3076 generates a repulsive force, thereby driving the rotating plate 3078 to rotate to the corresponding position of the through hole 30711 and the second through groove 30713, so as to facilitate the smooth return of the bottom plate 1. It is necessary to coat the outer wall of the fixed box 301 and the outer wall of the transverse air box 3081 with a magnetic shielding protective coating. The magnetic shielding protective coating is used to perform magnetic shielding protection on the magnetic plate and the conductive rod 3084 in the transverse air box 3081 to prevent the high-voltage equipment in the car from generating electromagnetic interference to the magnetic plate and to prevent the current generated by the conductive rod 3084 from being affected.

[0025] Working principle: When working, first install the equipment to be installed on the top of the bottom plate 1 for use. When protecting, when the top of the bottom plate 1 is subjected to impact force, the bottom plate 1 moves downward under the action of pressure, so that the buffer seat 203 is compressed for buffering. When the buffer seat 203 is compressed, new deformation is generated, and the impact force on the bottom plate 1 is further released through the recessed portion 204, thereby improving the buffering protection of the top equipment of the bottom plate 1. When the bottom plate 1 moves downward, the top of the top rod 303 is inserted into the positioning groove 101, thereby pushing the movable block 302 to move downward, so that the first spring 304 is compressed. Under the left and right of the first spring 304, the impact force is further buffered, thereby improving the protection effect. When the buffer seat 203 is compressed, the air inside the recessed portion 204 enters the second air groove 3053 through the first air groove 3051 and the connecting groove 3052, and enters the fixed box 301 through the air cavities 3055 on both sides of the fixed box 301 into the space above the pressing piston 30612, thereby generating downward pressure on the pressing piston 30612, thereby pushing the pressing piston 30612 to move toward the side of the movable block 302, pushing the pressing block 30610 to move downward, causing one end of the rotating push plate 3068 to move downward, so that after the rotating push plate 3068 rotates around the fixed axis 3067, the other end moves upward to push the longitudinal moving block 3065 to move upward, and then pushes the two clamping blocks 3063 to move outward through the connecting rod 3064 and clamp them into the clamping groove 102, thereby improving the installation stability of the bottom plate 1 and the upper plate 201, thereby improving the stability of the equipment; When air enters the fixed box 301 through the air cavity 3055, the first through slot 30710 on the rotating plate 3078 corresponds to the second through slot 30713 on the fixed plate 30712, so that air can smoothly enter the fixed box 301. When the movable block 302 moves downward, the transverse piston 3083 is pushed toward the exhaust hole 3082 by air pressure transmission, so that the conductive rod 3084 cuts the magnetic flux lines between the first magnetic plate 3086 and the second magnetic plate 3087, so that the conductive rod 3084 generates current, and the current is passed into the electromagnet 3077 through the conductive strip 3085, so that the electromagnet 3077 generates an attraction to the magnetic block 3076, thereby ensuring the corresponding stability of the first through slot 30710 and the second through slot 30713. When the impact force disappears, the movable block 302 moves back under the elastic force of the first spring 304, so that Under the pressure transmission, the transverse piston 3083 moves back toward the side of the fixed box 301, so that the conductive rod 3084 moves in the opposite direction, so that the conductive rod 3084 generates a reverse current and passes into the electromagnet 3077, so that the electromagnet 3077 generates a repulsive force on the magnetic block 3076, pushing the tooth plate 3073 to move, and the tooth plate 3073 is meshed with the gear ring 3079, thereby driving the rotating plate 3078 to rotate, so that the second through groove 30713 corresponds to the through hole 30711, and when the first spring 304 moves upward, it pushes the upper air to flow back toward the inside of the recessed portion 204, and when the air flows back through the through hole 30711, the air flow back speed is slowed down by the obstruction of the rotating plate 3078, thereby consuming the energy accumulated in the first spring 304 when under pressure, thereby playing a shock absorbing role on the first spring 304, so that the bottom plate 1 moves back smoothly, thereby protecting the top equipment of the bottom plate 1.
