Description

[Technical Field]

[0001] The present invention relates to a pneumatic energy generating device, and more particularly to a pneumatic energy generating device that effectively assists human muscle strength by providing either continuous pneumatic energy or explosive pneumatic energy to a driving machine in response to the characteristic that human muscles operate with two types of energy supply plans. [Background technology]

[0002] Generally, a wearable robot is a means worn by a person to support or assist the muscle strength of the human body, and most of them employ hydraulic devices to generate large force.

[0003] The previously filed patent document 1: Korean Patent Publication No. 10-2012-0105194 (September 25, 2012) discloses a wearable robot with improved weight, volume, noise, vibration, and energy efficiency.

[0004] The wearable robot according to the prior art is connected to the upper and lower legs, respectively, and supplies hydraulic pressure to hydraulic actuators, such as hydraulic cylinders, that assist leg movement. The wearable robot includes a hydraulic device, which includes a hydraulic pump and a flow control valve.

[0005] The hydraulic pump is installed in a supply flow path connecting an oil tank storing hydraulic oil to a hydraulic actuator. The hydraulic pump is connected to the oil tank storing hydraulic oil and configured to pressurize the hydraulic oil stored in the oil tank, and is driven by an electric motor. That is, the electric motor and hydraulic pump pressurize the hydraulic oil and supply it to the hydraulic actuator. The hydraulic pump may be connected to the electric motor and configured as a unidirectional hydraulic pump. The electric motor is controlled to operate by a control signal from a motor controller, and the motor controller receives a control signal from a main controller and outputs a corresponding control signal to the motor.

[0006] The flow control valve is installed in a discharge passage that branches off from a supply passage connecting the hydraulic actuator and the hydraulic pump and discharges hydraulic pressure. The operation of the flow control valve is controlled by a control signal from a valve controller, which generates and outputs a signal to control the operation of the flow control valve in response to a control signal output from the main controller. In this case, a pressure sensor is installed in the supply passage that supplies hydraulic fluid to the hydraulic actuator, and a signal processor processes the output signal of the pressure sensor and transmits it to the main controller. In addition, a check valve is installed in the supply passage between the hydraulic actuator and the hydraulic pump.

[0007] The above-mentioned conventional technology has a problem that it is difficult for a user to bear the weight of the oil tank and other components, which are relatively large in volume, and it is difficult to concentrate on the task at hand when performing another task, because the components are composed of an oil tank, a hydraulic pump, and a hydraulic actuator.

[0018] In an embodiment of the present invention, the air pressure generating member may include: a dual piston disposed inside the upper part of the upper housing, communicating with the air pressure supply member, and supplying air pressure generated through linear reciprocating motion to the air pressure supply member; and a motor connected to at least a portion of the dual piston, supplying a rotational force to at least a portion of the dual piston to linearly reciprocate the dual piston.

[0019] In an embodiment of the present invention, a seating member on which the lower end of the liquefied gas chamber is seated is formed at the lower inside of the lower housing, and the central part of one side of the lower housing may be opened so that the liquefied gas chamber can be detachably attached to the inside of the lower housing.

DETAILED DESCRIPTION OF THE INVENTION

However, the present invention may be realized in various different forms and is not limited to the embodiments described herein.

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0027] 1. First Example Hereinafter, a pneumatic energy generating apparatus according to a first embodiment of the present invention will be described with reference to FIGS.

[0028] FIG. 1 is a perspective view in one direction showing a pneumatic energy generating apparatus according to a first embodiment of the present invention.

[0029] Referring to FIG. 1, a pneumatic energy generator 100 according to a first embodiment of the present invention is a liquefied gas-based pneumatic energy generator 100 for operating biomimetic pneumatic artificial muscles, and includes at least one pneumatic pressure generator 110, at least one pneumatic pressure intensifier 120, and a controller 130.

[0030] Here, the liquefied gas may include all gases that can be liquefied, and the liquefied gas in the present invention will be described as liquefied nitrogen (N2).

[0031] Fig. 2 is a perspective view in one direction showing a detailed configuration of the pneumatic energy generating device according to the first embodiment of the present invention, and Fig. 3 is a conceptual diagram showing a process in which the pneumatic energy generating device according to the first embodiment of the present invention generates pneumatic energy.

[0032] 2 and 3, the air pressure generating unit 110 includes an upper housing 111, an air pressure supply member 112, an air pressure generating member 113, a safety valve 114, and a flow path adjusting valve 115.

[0033] The upper housing 111 has an internal space formed therein so as to accommodate the air pressure supply member 112 and the air pressure generating member 113 .

[0034] In addition, a lower housing 121 (to be described later) is coupled to the lower part of the upper housing 111 .

[0035] The air pressure supply member 112 (reservoir) has a hollow shape with an open interior, and supplies stored air pressure energy to the driving machine 10 .

[0036] Specifically, the air pressure supply member 112 is connected to the air pressure generating member 113 and receives the pressure generated by the air pressure generating member 113. The air pressure supply member 112 stores air pressure energy generated by the pressure applied thereto and then supplies the stored air pressure energy to the driving machine 10 to operate the driving machine 10.

[0037] The air pressure generating member 113 adjusts the pressure of the air pressure supply member 112 to generate air pressure energy.

[0038] The air pressure generating member 113 for this purpose includes a dual piston 113a and a motor 113b.

[0039] The dual piston 113a is disposed inside the upper housing 111 and communicates with the air pressure supply member 112, and supplies air pressure generated through linear reciprocating motion to the air pressure supply member.

[0040] Specifically, the dual piston 113a may include a rotating plate that is connected to the motor shaft of the motor 113b and rotates, a connecting rod that is linked to the rotating plate on one side, a piston that is linked to the other side of the connecting rod and moves back and forth in a linear manner, and a guide member that is formed to surround the piston and guides the linear reciprocating motion of the piston.

[0041] The motor 113b is coupled to at least a portion of the dual piston 113a and supplies a rotational force to at least a portion of the dual piston 113a, causing the dual piston 113a to perform a linear reciprocating motion.

[0042] The safety valve 114 is located inside the upper housing 111 and communicates with the air pressure supply member 112 .

[0043] In addition, the safety valve 114 is normally kept closed and opens when the pressure of the air pressure supply member 112 falls outside a preset safe pressure range, and reduces the pressure of the air pressure supply member 112 by discharging part of the air in the air pressure supply member 112, thereby preventing the air pressure supply member 112 from exploding due to the pressure.

[0044] The flow path control valve 115 is connected between the liquid gas chamber 123 and the liquid fluid chamber 126, and is opened or closed depending on the pressure of the air pressure supply member 112 to adjust the amount of liquid fluid supplied to the liquefied gas chamber 123.

[0045] By way of example, the flow path control valve 115 may be a solenoid valve, but is not limited thereto, and may be any valve (e.g., a manual valve) that functions to block or allow flow in the flow path.

[0046] Here, the liquid fluid may be a liquid containing water, antifreeze, or the like.

[0047] The air pressure intensifying unit 120 selectively mixes liquid fluid with liquefied gas by the pressure of the air pressure supply member 112 and selectively vaporizes the liquefied gas, thereby increasing air pressure energy and simultaneously cooling the air pressure generating member 113.

[0048] Here, the main function of the air pressure intensifier 120 is to quickly generate high pressure in the air pressure supply member 112, and the secondary function of the air pressure intensifier 120 is to cool the air pressure generating member 113b.

[0049] Specifically, if the air pressure generating member 113b is operated repeatedly, overheating may occur in the air pressure generating member 113b, resulting in a decrease in performance.

[0050] The reason for the decrease in performance is that as the temperature increases, the motor's magnetic flux density decreases, resulting in a decrease in output.

[0051] To address this performance degradation, the air pressure intensifier 120 injects low-temperature nitrogen gas, which is vaporized liquefied gas, onto the air pressure generating member 113b to cool it. The air pressure intensifier 120 vaporizes the liquefied gas in the air pressure intensifier 120 and delivers it to the air pressure supply member 112 to inject low-temperature nitrogen gas onto the air pressure generating member 113b. The air pressure intensifier 120 continues to attempt vaporization above the preset safety pressure range of the safety valve 114. When the low-temperature nitrogen gas is subsequently discharged through the safety valve 114, it comes into direct contact with the nearby overheated air pressure generating member 113b, thereby cooling the overheated air pressure generating member 113b.

[0052] 2 and 3, the air pressure enhancing unit 120 includes a lower housing 121, a fitting member 122, a liquid / gas chamber 123, a check valve 124, a sensor 125, a liquid fluid chamber 126, and a battery 127.

[0053] The lower housing 121 is coupled to the lower part of the upper housing 111 and has an internal space formed therein to accommodate the liquid gas chamber 123 and the liquid fluid chamber 126 .

[0054] Also, a seating member 121a is formed at the lower interior side of the lower housing 121, on which the lower end of the liquefied gas chamber 123 is seated.

[0055] 2, a liquefied gas chamber 123 is detachably opened inside the lower housing 121 at the center of one side of the lower housing 121. As shown in FIG.

[0056] As a result, at least a portion of the liquefied gas chamber 123 coupled to the inside of the lower housing 121 is exposed to the outside.

[0057] The fitting member 122 is located on the upper interior side of the lower housing 121 . Furthermore, the fitting member 122 connects the air pressure supply member 112 and the liquid / gas chamber 123 .

[0058] 4(a) and 4(b) are graphs showing pressure curves as a function of temperature for carbon dioxide used in the prior art and nitrogen used in the pneumatic energy generating apparatus according to the first and second embodiments of the present invention. Fig. 5 is a perspective view in one direction showing the liquefied gas chamber provided in the pneumatic energy generating apparatus according to the first embodiment of the present invention.

[0059] Referring to FIG. 5, the liquid / gas chamber 123 has an internal space formed therein to accommodate liquefied gas.

[0060] Specifically, the liquid / gas chamber 123 may have a cylindrical shape, and the upper part of the liquid / gas chamber 123 communicates with the fitting member 122 .

[0061] In the present invention, liquid nitrogen is used to generate pneumatic energy, whereas the prior art used carbon dioxide.

[0062] When carbon dioxide (CO2) is used, it is collected at room temperature and atmospheric pressure, and then the pressure is reduced to turn it into a liquid state.

[0063] Conversely, to vaporize carbon dioxide, the carbon dioxide in a liquid state is exposed to room temperature and atmospheric pressure conditions.

[0064] Referring to FIG. 4(a), carbon dioxide is liquefied under relatively high pressure, so storing liquefied carbon dioxide requires a very hard, thick, and heavy container, such as a high-pressure air tank.

[0065] If a lightweight, compact container such as a bicycle carbon dioxide cartridge or a carbonated water cartridge is used, it cannot hold a large amount of air.

[0066] On the other hand, referring to FIG. 4(b), nitrogen (N2) is more affected by temperature than by pressure when liquefied compared to carbon dioxide.

[0067] Generally, liquefied nitrogen (N2) is a by-product produced during the process of obtaining liquefied oxygen, and is an economical, environmentally friendly, and chemically stable substance.

[0068] In particular, its volume can expand 600 to 700 times when it changes phase from a liquid state to a gas state at room temperature and atmospheric pressure, making it a promising pneumatic energy source that can supply explosively high pressure and flow rate.

[0069] Furthermore, since liquefied gas remains liquid at extremely low temperatures of minus 200 degrees Celsius, the ambient temperature can be raised to vaporize the liquid nitrogen.

[0070] Conversely, in order to store liquefied gas in a liquid state for a long period of time, an insulated container is required that can isolate it from the surrounding room temperature, which is relatively very hot, and therefore, it is preferable that the liquid / gas chamber 123 is made of a material that can provide insulation.

[0071] The liquid / gas chamber 123 for storing liquefied gas does not need to withstand high pressure, and rather, its insulating ability is a more important feature.

[0072] Such a liquid / gas chamber 123 can be manufactured relatively more compact and lighter, and has the advantage of being compact and lighter than other carbon dioxide tanks or pressurized air tanks, while still providing a large capacity.

[0073] Specifically, the liquid / gas chamber 123 may be formed in a structure similar to that of a thermos bottle, and such a liquid / gas chamber 123 has a vacuum layer between the outer and inner walls, which limits the heat transfer method to radiation only, thereby providing a heat insulating function.

[0074] The check valve 124 is located inside the upper part of the lower housing 121 and is connected between the pneumatic air supply member 112 and the liquefied gas chamber 123 .

[0075] Specifically, the check valve 124 is closed in the direction from the air pressure supply member 112 to the liquefied gas chamber 123 and is open in the direction from the liquefied gas chamber 123 to the air pressure supply member 112 .

[0076] FIG. 6 is a graph showing pressure over time when the pneumatic energy generating apparatus according to the first and second embodiments of the present invention generates continuous pneumatic energy and explosive pneumatic energy and supplies the energy to a driving machine.

[0077] Referring to FIG. 6, the sensor 125 includes a temperature sensor 125a and a pressure sensor 125b, which are respectively coupled to the air pressure supply member 112 and measure the temperature and pressure of the air pressure supply member 112.

[0078] The temperature sensors 125 a are connected to the air pressure supply members 112 respectively to measure the temperatures of the air pressure supply members 112 .

[0079] The temperature sensor 125 a transmits the measured temperature of the air pressure supply member 112 to the control unit 130 .

[0080] The pressure sensors 125b are respectively connected to the air pressure supply members 112 to measure the pressure of the air pressure supply members 112.

[0081] The pressure sensor 125b transmits the measured pressure of the air pressure supply member 112 to the control unit .

[0082] The liquid fluid chamber 126 has a hollow shape with an open interior so that a liquid fluid can be contained therein.

[0083] Additionally, the liquid fluid chamber 126 can share the same space as the pneumatic supply member 112 (reservoir).

[0084] Furthermore, the liquid fluid chamber 126 is disposed inside the lower housing 121 so as to be adjacent to the liquefied gas chamber 123 .

[0085] The liquid fluid chamber 126 supplies liquid fluid to the inside of the liquefied gas chamber 123 according to the pressure difference between the liquid fluid chamber 126 and the liquefied gas chamber 123, which changes depending on whether the flow path control valve 115 is open or closed.

[0086] The battery 127 is located within the lower housing 121 adjacent to the liquefied gas chamber 123 and the liquid fluid chamber 126 .

[0087] The battery 127 supplies power to the air pressure generating member 113, the safety valve 114, the flow path adjusting valve 115, the check valve 124, the sensor 125, and the control unit 130.

[0088] 7(a), (b), and (c) are conceptual diagrams showing that the pneumatic energy generating devices according to the first and second embodiments of the present invention generate pneumatic energy by adjusting the pressure and the amount of liquid fluid supplied.

[0089] The control unit 130 controls the operation of the air pressure generating member 113 so that the air pressure supplying member 112 supplies either continuous air pressure energy or explosive air pressure energy to the driving machine 10 .

[0090] Here, the air pressure energy may include continuous air pressure energy for continuously supplying energy lower than a preset energy and explosive air pressure energy for instantaneously supplying energy higher than a preset energy.

[0091] Specifically, as shown in FIG. 7(a), if only the air pressure generating member 113 is operated, a low pressure is continuously supplied, thereby providing continuous air pressure energy.

[0092] On the other hand, when the driving machine 10 requires a relatively high output, the pressure generated by the air pressure generating member 113 alone cannot provide sufficient air pressure energy, so additional explosive air pressure energy must be stored in the air pressure supply member 112 (reservoir) via the air pressure strengthening unit 120.

[0093] Here, the explosive air pressure energy includes a first explosive air pressure energy and a second explosive air pressure energy, and the second explosive air pressure energy has a higher output than the first explosive air pressure energy.

[0094] As a result, as shown in (b) of Figure 7, after the air pressure generating member 113 initially pressurizes the air pressure supply member 112, when the solenoid valve 115b is opened so that the liquid fluid contained in the liquid fluid chamber 126 can be injected into the liquefied gas chamber 123, the liquid fluid can be injected little by little into the liquefied gas chamber 123.

[0095] More specifically, the liquid fluid contained in the liquid fluid chamber 126 is forced into the interior of the liquefied gas chamber 123 by the nature of pressure equilibrium due to the pressure difference between the relatively low pressure liquefied gas chamber 1236 and the air pressure supply member 112 (reservoir).

[0096] The liquefied gas chamber 123 has two inlets connected to the check valve 124 and the flow path control valve 115. When the flow path control valve 115 is closed, a pressure difference occurs between the liquefied gas chamber 123 and the air pressure supply member 112 (reservoir), while when the flow path control valve 115 is opened, the pressure is balanced.

[0097] Here, as described above, the check valve 124 is closed in the direction from the air pressure supply member 112 (reservoir) to the liquefied gas chamber 123, and is open in the direction from the liquefied gas chamber 123 to the air pressure supply member 112 (reservoir).

[0098] As shown in FIG. 7(b), when supplying the first explosive air pressure energy, the air pressure generating member 113 is used to first fill the air pressure supply member 112 (reservoir) with an appropriate low pressure, and the flow path control valve 115 is opened or closed at short time intervals to inject liquid fluid. As the liquid fluid gradually leaves the liquefied gas chamber 123, an appropriate amount of vaporization can be generated, and the first explosive air pressure energy required for the driver 10 can be generated through this.

[0099] 7(c), in order to transmit high-power second explosive air pressure energy to the driver 10, the pressure of the air pressure supply member 112 (reservoir) is initially increased to the maximum that the air pressure generating member 113 can generate, and then the flow path control valve 115 is opened for a sufficient time so that the liquid fluid can be sprayed at high pressure into the liquefied gas chamber 123. As the liquid fluid is sprayed at high pressure, the liquefied gas in the liquefied gas chamber 123 is rapidly vaporized and transmitted to the air pressure supply member 112 (reservoir) through the check valve 124.

[0100] As a result, a large amount of air is instantaneously generated, and the pressure in the air pressure supply member 112 (reservoir) increases rapidly.

[0101] In addition, the control unit 130 controls the operation of the air pressure generating member 113 and the flow path control valve 115 so that the pressure amount generated by the air pressure generating member 113 and supplied to the air pressure supply member 112 and the vaporization amount of the liquefied gas maintain a preset ratio.

[0102] In addition, the control unit 130 may be equipped with a control algorithm that detects the operating state according to the temperature of the air pressure supply member 112 transmitted from the temperature sensor 125a, the pressure of the air pressure supply member 112 transmitted from the pressure sensor 125b, and previously input commands.

[0103] Here, the operating states include: 1) a state in which the pressure generated by the air pressure generating member 113 is generated at the same pressure as the pre-designed pressure of the air pressure generating member 113 and is supplied to the air pressure supply member 112 and stored in the air pressure supply member 112; 2) a state in which the air pressure generating member 113 is overheated and the pressure according to the previously input command is lower than the pre-designed pressure; 3) a state in which the liquefied gas inside the liquefied gas chamber 123 is consumed and no longer exists; and 4) a state in which some liquefied gas exists inside the liquefied gas chamber 123.

[0104] Hereinafter, the operation of the pneumatic energy generating apparatus according to the first embodiment of the present invention will be described with reference to FIGS.

[0105] FIG. 3 shows a process of generating pneumatic energy to be provided to the driving machine 10 through the pneumatic energy generating device 100 according to the first embodiment of the present invention. As shown in FIG. 3, pneumatic energy is generated through an air pressure generating unit 110 and an air pressure enhancing unit 120, which are mutually complementary.

[0106] Specifically, the air pressure generating unit 110 contributes to compressing a liquid fluid at high pressure to operate the air pressure enhancing unit 120, and the air pressure enhancing unit 120 contributes to cooling so that the air pressure generating unit 110 can continuously perform at a constant level.

[0107] The air pressure energy generated by the air pressure generating unit 110 and the air pressure enhancing unit 120 is stored together in an air pressure supplying member 112 (reservoir) and then transmitted to the driving machine 10 .

[0108] Referring to FIG. 6, the air pressure generating unit 110 can continuously supply sufficient energy for a long period of time to assist the driving machine in low-intensity exercise.

[0109] Specifically, in the graph shown at the top of FIG. 6, the pressure peaks at 350 kPa and then decreases continuously.

[0110] The reason for the above is that when the driver 10 continuously uses the pressure stored in the air pressure supply member 112 (reservoir), the amount of air stored in the air pressure supply member 112 (reservoir) is instantaneously transferred to the driver 10, causing pressure fluctuations, and the air pressure generating member 113 continues to operate, maintaining the pressure at 350 kPa.

[0111] The air pressure intensifier 120 can instantaneously generate explosive high-output input power, so that even when the driving machine 10 is driven, large pressure fluctuations do not occur in the air pressure supply member 112 (reservoir).

[0112] If the air pressure generating unit 110 and the air pressure intensifying unit 120 are used simultaneously, the air pressure energy generated by the air pressure generating unit 110 and the air pressure intensifying unit 120 is stored together in the air pressure supply member 112 (reservoir), and high-power air pressure energy can be instantaneously provided by the air pressure intensifying unit 120, while pressure energy can be continuously provided by the air pressure generating unit 110.

[0113] FIG. 8 is a conceptual diagram illustrating a process in which the pneumatic energy generating apparatus according to the first embodiment of the present invention adjusts the pressure of the pneumatic supply member to transmit sustained pneumatic energy and explosive pneumatic energy to a driving machine.

[0114] Referring to FIG. 8, when the pressure of the air pressure supply member 112 is increased by the air pressure generating member 113, the flow path control valve 115 is opened, and the liquid fluid contained in the liquid fluid chamber 126 is supplied into the liquid gas chamber 123. As a result, the liquid nitrogen is vaporized, and the air cooled by the vaporization process is supplied to the air pressure supply member 112, thereby cooling the motor 113b adjacent to the air pressure supply member 112.

[0115] Referring to FIG. 8, the present invention can supply low ab-force energy sustainably by operating only the air pressure generating unit 110, and can supply low air pressure energy sustainably to the driver 10 by simultaneously operating the air pressure generating unit 110 and the air pressure enhancing unit 120, and can simultaneously supply high air pressure energy (high power) to the driver 10, thereby enabling the driver 10 to output power sustainably and instantaneously output high power (amplification).
