[0028] Figure 1-5 The utility model shows a structural schematic diagram of a shock absorbing protection device for installing a battery circuit board of a column-adjustable intercom. Please refer to Figure 1-Figure 5 In this embodiment, a shock absorbing protection device for installing a battery circuit board of a train-controlled intercom includes a housing 100, a battery circuit board 200, a limit assembly 300 and a deceleration assembly 400.

[0029] The side wall of the shell 100 is provided with an installation groove 110, and an elastic member 120 is installed on the inner wall of the installation groove 110. Two groups of first springs 130 are symmetrically installed on the inner wall of the installation groove 110 with the elastic member 120 as the center, wherein each group of first springs 130 has two, and the inner wall of the installation groove 110 is symmetrically provided with two guide grooves 140.

[0030] The battery circuit board 200 is located inside the mounting groove 110, the side wall of the battery circuit board 200 abuts against the other end of the first spring 130, the side wall of the battery circuit board 200 abuts against the side wall of the elastic member 120, the side wall of the battery circuit board 200 is provided with a placement groove 210, the battery circuit board 200 is slidably connected inside the mounting groove 110, when impacted, the battery circuit board 200 moves toward the inside of the mounting groove 110, the battery circuit board 200 squeezes the elastic member 120 and the first spring 130, the elastic member 120 and the first spring 130 buffer the impact force to prevent the battery circuit board 200 from being damaged by pressure.

[0031] The limiting assembly 300 is installed on the side wall of the battery circuit board 200 to limit and fix the battery circuit board 200 in the installation groove 110. The limiting assembly 300 includes a fixing frame 310 installed in the placement groove 210, a slide plate 320 slidably connected to the fixing frame 310, a second spring 330 installed on the side wall of the slide plate 320, and a limiting plate 340 installed on the other side wall of the slide plate 320 and extending out of the side wall of the fixing frame 310. The limiting plate 340 has an arc surface 350 on one side wall facing the elastic member 120. When the battery circuit board 200 is installed, the battery circuit board 200 is pushed to drive the limiting assembly 300 to move into the installation groove 110 until the arc surface 350 abuts against the outer edge of the installation groove 110. As the battery circuit board 200 moves into the installation groove 110, the installation groove 110 squeezes the limiting plate 340 along the arc surface 350 to move into the fixing frame 310, and the limiting plate 340 pushes the slide plate 330 to move into the fixing frame 310. 20 squeezes the second spring 330 until the limit plate 340 is retracted into the fixed frame 310. As the battery circuit board 200 continues to move into the mounting slot 110, until the fixed frame 310 moves to the tail end of the guide slot 140, the second spring 330 rebounds and pushes the slide plate 320 and the limit plate 340 to move out of the fixed frame 310. The limit plate 340 extends into the guide slot 140, and the elastic member 120 and the first spring 130 push the battery circuit board 200 and the limit plate 340 to move out of the mounting slot 110. The straight edge of the limit plate 340 abuts against the tail end of the guide slot 140 to limit the battery circuit board 200 in the mounting slot 110. When the battery circuit board 200 moves into the mounting slot 110, the limit plate 340 slides toward the front end of the guide slot 140. When the battery circuit board 200 needs to be removed, the slide plate 320 is pulled to drive the limit plate 340 to be retracted into the fixed frame 310.

[0032] The deceleration assembly 400 includes a tube body 410 installed on the inner wall of the installation groove 110, a piston 420 located inside the tube body 410, and a connecting rod 430 installed on the side wall of the piston 420. A suction cup 440 is installed on the other end of the connecting rod 430. An air hole 450 is opened on the outer wall of the tube body 410. When the battery circuit board 200 moves to abut against the elastic member 120 and the first spring 130, the suction cup 440 is adsorbed on the side wall of the battery circuit board 200 to connect the connecting rod 430 with the battery circuit board 200. As the battery circuit board 200 is impacted and moves toward the inside of the installation groove 110, the battery circuit board 2 00 pushes the connecting rod 430 and the piston 420 to move toward the inside of the tube body 410 and squeezes the air inside the tube body 410 out from the air hole 450, and uses air pressure to cooperate with the elastic member 120 and the first spring 130 to buffer the impact force. When the elastic member 120 and the first spring 130 rebound and push the battery circuit board 200 to move outside the installation groove 110, the battery circuit board 200 drives the connecting rod 430 and the piston 420 to move outside the tube body 410, and the external air enters the inside of the tube body 410 through the air hole 450, and uses air pressure to decelerate the rebound of the elastic member 120 and the first spring 130.
