Human support system

Abstract

A human body support system includes a human body support component and a main unit. The main unit includes a compressor and a control unit. The control unit is connected to an air supply source within the compressor and to the human body support component. The control unit includes a pressure relief module. The pressure relief module selectively provides overcharge protection to the human body support component based on the identification status provided by the connected human body support component. Based on the identification status, the pressure relief module provides one of several modes from a set of multiple modes, including a no-pressure-relief mode and a pressure-relief mode. This allows for the activation or deactivation of overcharge protection according to different connected human body support components, improving application flexibility and providing matching overcharge protection conditions to enhance system adaptability.

Claims

1. A human body support system, comprising: a human body support component having an inflatable airbag structure, which provides support for at least a portion of the human body through inflation; and a main unit, comprising: A compression device provides a gas supply; A control device is provided, connected to the air supply source and the human body support assembly, to allow the air supply source to connect to the human body support assembly. The control device includes a pressure relief module, wherein the pressure relief module selectively provides overcharge protection to the human body support assembly based on an identification state provided by the connected human body support assembly. The pressure relief module provides one of several modes based on the identification state. When the overcharge protection is provided, if the human body support assembly is overcharged, the pressure relief module connects a venting path to reduce the actual inflation pressure value of the human body support assembly. The modes include: a no-pressure relief mode, in which the venting path is not connected; and a first pressure relief mode, in which, when the inflation pressure provided to the human body support assembly meets a first overcharge state, the venting path is connected to prevent the inflation pressure from meeting the first overcharge state.

2. The human body support system as claimed in claim 1, wherein the control device includes a socket for connecting a connector of the human body support assembly to the air supply source via the socket, wherein the pressure relief module is coupled to the socket, and the connector is provided with an identification unit for engaging the pressure relief module and providing the identification status.

3. The human body support system as claimed in claim 2, wherein the identification unit is a blocking element for closing the venting path when the connector of the human body support assembly is connected to the socket, wherein the blocking element enables the pressure relief module to provide the pressure-free mode.

4. The human body support system as claimed in claim 2, wherein the identification unit is an adjustment element that extends into the pressure relief module to set the identification state when the connector is connected to the socket, wherein the adjustment element causes the pressure relief module to provide the first pressure relief mode.

5. The human body support system as described in claim 2, wherein the socket is configured with a mounting portion for mounting the pressure relief module, the pressure relief module comprising: A housing assembly defines a first vent, a second vent, and a chamber connecting the first vent and the second vent, wherein the first vent provides communication with the air supply source to the chamber, and the second vent provides communication with the outside to the venting path for venting; and a valve assembly disposed in the chamber, comprising: a valve unit and a resilient unit, wherein the valve unit, by means of the resilient unit, forms a thrust against the first vent to close the first vent and thereby block the venting path.

6. The human body support system as described in claim 5, wherein in the first depressurization mode, when the inflation pressure provided to the human body support component meets the first overcharge state, the valve unit is pushed based on the inflation pressure to release the closed state of the first vent, and the depressurization path connects to the outside and depressurizes until the inflation pressure no longer meets the first overcharge state.

7. The human body support system as claimed in claim 5, wherein when the identification unit is a blocking element, the blocking element is used to plug the mounting portion to close the second vent when the connector of the human body support assembly is connected to the socket, thereby blocking the venting path and enabling the pressure relief module to provide the pressure-free mode.

8. The human body support system as claimed in claim 5, wherein the valve assembly further includes a chassis that cooperates with the elastic unit, the chassis being ventilated and movable between the first vent and the second vent, the chassis also supporting one end of the elastic unit, the other end of the elastic unit abutting against the valve unit, the thrust being defined by the degree to which the chassis is moved between the first vent and the second vent, wherein... When the identification unit is an adjustment element, when the connector is connected to the socket, the adjustment element extends into the pressure relief module to push the chassis to the corresponding position between the first vent and the second vent, thereby setting the identification state.

9. The human support system as claimed in claim 8, wherein corresponding pressure relief modes are defined by the lengths of different adjusting elements, wherein these modes further include: a second pressure relief mode, wherein when the inflation pressure meets a second overcharge condition, the valve unit releases the closure of the first vent until the inflation pressure does not meet the second overcharge condition; and a third pressure relief mode, wherein when the inflation pressure meets a third overcharge condition, the valve unit releases the closure of the first vent until the inflation pressure does not meet the third overcharge condition, wherein, The first overcharge pressure threshold under the first overcharge state is less than the second overcharge pressure threshold under the second overcharge state, and the second overcharge pressure threshold under the second overcharge state is less than the third overcharge pressure threshold under the third overcharge state.

10. The human body support system as claimed in claim 5, wherein the venting path of the pressure relief module communicates with the interior of the connector to provide a venting method for venting through gaps in the assembly structure of the connector.

11. The human body support system as claimed in claim 1, wherein the control device includes a socket for connecting a connector of the human body support assembly to the air supply source via the socket, wherein the pressure relief module is not coupled to the socket, and the connector is provided with an identification unit for cooperating with the control device and providing the identification status.

12. The human support system as claimed in claim 11, wherein the identification unit is a sensing element, and when the connector is connected to the socket, the control device obtains the identification state by means of the sensing element, and the control device generates a control command based on the identification state to control the pressure relief module so that the pressure relief module performs one of the corresponding modes.
