[0041] The left side of the control valve body 401 is provided with a first air guiding tube 408 and a second air guiding tube 415, wherein the first air guiding tube 408 is connected to the gas container 7, and the second air guiding tube 415 is The connecting pipe 3 is connected. The first air duct 408 and the second air duct 415 are both connected to the first recess 416. The first air duct 408 and the second air duct 415 are also associated with the second recess 417.

[0042] Further, as shown in FIG. 5, the fixed shaft 409 is connected to the second needle valve 414, the fixed shaft 409 is also connected to the slot 410, and the motor drive key 412 is disposed on The motor drive key 412 is coupled to the slot 410 on the motor 411. When the motor 411 is rotated, the motor drive key 412 drives the slot 410 to move downward or upward through the motor drive key 412. Since the fixed shaft 409 is connected to the second needle valve 414, Moving downward or upward of the slot 410 will drive the second needle valve 414 Move down. Specifically, when the motor 411 rotates counterclockwise, the groove 410 moves downward, the groove 410 moves downward and drives the second needle valve 414 to move downward, and the second needle valve 141 Disengaged from the tip of the second groove 417. When the motor 411 rotates 吋, the groove 410 moves up and down, the groove 410 moves upward and drives the second needle valve 414 to move upward, the second needle valve 141 and the second The tip of the groove 417 is fitted. In this embodiment, the groove piece 410 is a U-shaped groove piece.

[0043] The second needle valve 414 is disposed in the second groove 417, and the second needle valve 414 moves up and down in the second groove 417. The second sealing ring 413 is disposed in the second groove 417 for preventing the second groove 417 from leaking.

[0044] The compressed gas in the gas container 7 is input to the valve 4 through the first air guiding tube 408, and is input to the connecting pipe 3 through the second air guiding pipe 415, and then the compressed gas is input to the air by the connecting pipe 3. Belt 2

[0045] The top of the first needle valve 407 and the first groove 416 are both pointed structures, and the tops of the second needle valve 414 and the second groove 417 are also pointed structures.

[0046] As shown in FIG. 2, when the tip of the first needle valve 407 is in close contact with the tip of the first groove 416, and the tip of the second needle valve 414 is opposite to the first The tip of the two grooves 417 also closely fits, and the gas in the first air guiding tube 408 is blocked by the first needle valve 407 and the second needle valve 414, and does not flow into the second air guiding tube. 415.

As shown in FIG. 3, when the user pulls the first needle valve 407吋 by the draw tape 5, the first needle valve 407 moves to the left. When the tip of the first needle valve 407 is disengaged from the tip of the first groove 416, the gas in the first air tube 408 flows into the second air tube 415 through the first groove 416.

[0048] As shown in FIG. 4, when the user pulls the slot 410 through the motor 411 and drives the second needle valve 414 to move downward, the tip of the second needle valve 414 and the second The groove 417 is disengaged, and the gas in the first air pipe 408 flows into the second air pipe 415 through the second groove 417.

[0049] Further, the motor 411 is also electrically connected to the controller 70, and the controller 70 controls the rotation of the motor 411. The controller 70 is also electrically coupled to the gravity sensor 8. The gravity sensor 8 is configured to detect an acceleration of the old person falling into the automatic protection device, and when the acceleration of the old automatic safety device is a gravity acceleration 吋, indicating that the user is in a falling state, the controller 70 controls the The motor 411 rotates, the motor 411 pulls the slot 410 and drives the second needle valve 414 to move downward. The tip of the second needle valve 414 is disengaged from the second groove 417, and the gas in the first air pipe 408 flows into the second air pipe 415 through the second groove 417, and the gas enters the inflation. The belt 2 causes the inflatable belt 2 to bulge, buffering the impact of the fall, and reducing the damage caused by the fall.

[0050] The working principle of the old fall fall automatic protection device is as follows: The old fall fall automatic protection device is worn on a user protection part (for example, a knee part, a waist part, a hand joint part, etc.), and the pull band 5 is bound In the user's hand, when the user's body suddenly becomes severely tilted (for example, falls), the gravity sensor 8 detects that the acceleration of the old fall safety device is gravity acceleration, and the controller 70 controls the valve 4 The motor 411 rotates counterclockwise and drives the slot 410 to move downward. The slot 410 moves downward and drives the second needle valve 414 to move downward. The second needle valve 141 and the second The tip of the recess 417 is disengaged and the gas in the gas container 7 enters the second air duct 415 from the first air duct 408. At the same time, since the strap 5 is bound to the user's hand, when the user falls, the arm tension strap 5 pulls the first needle valve 407 to the left, and the first needle valve 407 and the tip of the first recess 416 The portion is detached, and the gas in the gas container 7 enters the second air guiding tube 415 from the first air guiding tube 40 8 . The gas in the second air guiding tube 415 is quickly inflated to the inflatable waist belt 2 through the connecting pipe 3, so that the inflatable waist belt 2 is rapidly inflated, so that the user can smash the impact force of the user to fall down and reduce the user's injury. After use, the user deflates the inflatable belt 2 through the deflation valve 1.

The above are only the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and the equivalent structure or equivalent process transformations made by the description of the present invention and the contents of the drawings may be directly or indirectly applied to other related The technical field is equally included in the scope of patent protection of the present invention.
