The power supply end of the power supply module is connected to the power input end of the control module, and the controllable electronic switch is connected between the power output end of the control module and the power supply end of the controllable valve. When the vehicle is in an unignition state and gas replacement is required, the power supply module operates in a first power supply mode and supplies power to the control module, so that the control module is in a power-on state.

[0017] In one embodiment, when the vehicle is in an unignition state and does not need to replace gas, the switching unit connects the controllable power supply unit to the control module, and the controllable power supply unit stops supplying power to the control module if it does not receive an enable signal.

[0065] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0066] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments made by ordinary technicians in this field based on the inspiration of these embodiments fall within the scope of protection of this application.

[0067] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the numbers used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0068] Fuel cells are widely used in vehicle batteries due to their high efficiency and pollution-free power generation. Fuel cells require a hydrogen supply from gas cylinders, but these cylinders undergo a hydrogen replacement process. For example, hydrogen cylinders used for transporting hydrogen are filled with highly stable nitrogen as a protective gas. Before the cylinders are filled with hydrogen, the nitrogen in the cylinders must be replaced with hydrogen to ensure the high-purity hydrogen required by the fuel cells.

[0069] In the prior art, low-voltage power supplies come from two sources. In one type of gas displacement device, the low-voltage power supply is provided by an uncontrolled power supply unit, which is derived from a low-voltage battery and can be directly connected, regardless of whether the vehicle is in the ignition state. In another type of gas displacement device, the low-voltage power supply is provided by a controllable power supply unit, which is derived from a low-voltage battery but is controlled by the vehicle controller (VCU). Because the VCU needs to be awakened when the vehicle is in the ignition state, the low-voltage power supply is only connected when the vehicle is in the ignition state. Figure 4 This is a structural diagram of a gas replacement device in the prior art. Figure 5 This is a schematic diagram of the structure of another gas replacement device in the prior art. On the one hand, hydrogen has the characteristics of being flammable and explosive, such as Figure 4 As shown, if the high voltage power of the hydrogen fuel cell bus is connected, the controllable power supply unit is connected to the low voltage battery, and the vehicle supplies low voltage power to the control module and the controllable valve on the body, there will be safety hazards during hydrogen replacement; secondly, if Figure 5 As shown in the figure, if the hydrogen fuel cell bus is only connected to low voltage but not ignited, the uncontrolled power supply unit supplies low voltage electricity to the control module and controllable valves. Although the safety hazard can be minimized during hydrogen replacement, the premature power supply causes the electronic control device to generate a certain amount of static current regardless of whether the replacement operation is performed. There are many controllers in the bus. To ensure that the low-voltage battery is not depleted, the total static current of all controllers cannot be too large, and the static current of each controller is also strictly limited. Figure 6 It is a structural diagram of another gas replacement device in the prior art, such as Figure 6 As shown, by using an independent power supply module to provide low voltage to the electronic control devices and cylinder valves involved in the replacement operation (without requiring power from the entire vehicle), the vehicle's power supply can be completely disconnected during the replacement operation. However, the application of existing gas replacement devices to vehicles raises other issues: the addition of an uninterruptible power supply (UPS) required to power the electronic control devices and cylinder valves not only complicates system layout, operation, and maintenance, but also results in cost and energy waste.

[0070] In summary, the existing technology has the problems of poor gas replacement operation convenience, poor safety and high static power consumption.

[0071] In response to the problems existing in the prior art, the inventors discovered during their research on a gas replacement device that the device comprises: a power supply module, a control module, a controllable electronic switch, and a controllable valve mounted on a main body; the main body is used to fill with gas; the power supply terminal of the power supply module is connected to the power input terminal of the control module, and the controllable electronic switch is connected between the power output terminal of the control module and the power supply terminal of the controllable valve; when the vehicle is in an unignited state and gas replacement is required, the power supply module operates in a first power supply mode and supplies power to the control module, causing the control module to be in a powered-on state; when operating in the first power supply mode, the power supply module also generates a closing instruction; the closing instruction is used to control the controllable electronic switch to be in a closed state, causing the controllable valve to open after power is applied. In this way, power is supplied to the controllable valve and the control module simultaneously only during gas replacement, eliminating the need for pre-powering. This solves the problem of high static power consumption in gas replacement operations in the prior art. The gas replacement device can complete the gas replacement process without the need for a host computer, solving the problem of poor convenience in gas replacement operations in the prior art. Since the vehicle is in an unignited state, it is not in a high-voltage powered state, solving the problem of poor safety in gas replacement operations in the prior art. Based on the above-mentioned inventive concept, the gas replacement device in this application is designed.

[0072] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0073] Figure 1 This is a schematic diagram of the structure of the gas replacement device provided in this application. Figure 1 As shown, in this embodiment, a gas displacement device 103 is located inside a vehicle 101, and a body 102 is used to charge the vehicle with gas. Specifically, the body 102 has a gas charging inlet 113 and a gas outlet 114. The gas displacement device 103 includes a power supply module 104, a control module 105, a controllable electronic switch 106, and a controllable valve 107 mounted on the body 102.

[0074] In the gas replacement device 103, the power supply terminal g1 of the power supply module 104 is connected to the power input terminal a2 of the control module 105. The controllable electronic switch 106 is connected between the power output terminal a1 of the control module 105 and the power supply terminal b1 of the controllable valve 107. The power output terminal of the control module 105 includes a positive terminal a11 and a negative terminal a12. The positive terminal a11 of the control module 105 is connected to the positive terminal b11 of the controllable valve 107, while the negative terminal a12 of the control module 105 is connected to the negative terminal b12 of the controllable valve 107 via the controllable electronic switch 106.

[0075] When the vehicle 101 is in an unignited state and requires gas replacement, the power supply module 104 operating in the first power supply mode is used to power the control module 105 and generate a close instruction and send a close instruction to the controllable electronic switch 106. When the vehicle 101 is in an unignited state and does not require gas replacement, the power supply module 104 does not need to power the control module. When the vehicle 101 is in an ignition state, the power supply module 104 operating in the second power supply mode is used to power the control module 105.

[0076] The control module 105 is configured to receive power from the power supply module 104 when the vehicle 101 is in an unignition state and needs to replace gas, and when the vehicle 101 is in an ignition state.

[0077] The controllable electronic switch 106 is configured to close the controllable electronic switch 106 upon receiving a closing instruction from the power supply module 104 .

[0078] The gas inlet 113 and gas outlet 114 of the body 102 are used for gas filling and gas discharge, respectively. The gas inlet 113 is unconditionally open and is used to charge hydrogen during gas replacement. The gas outlet 114 is controlled by the controllable valve 107. During gas replacement, when the controllable valve 107 is opened, the gas within the body 102 flows out of the gas outlet 114. For example, nitrogen within the body 102 flows out of the gas outlet 114.

[0079] Specifically, when a user needs to perform gas replacement, without igniting the vehicle 101, the user places the power supply module 104 in the first power supply mode. The power supply module 104 supplies power to the control module 105, generates a closing instruction, and sends a closing instruction to the controllable electronic switch 106 to control the controllable electronic switch 106 to be in a closed state. The closed controllable electronic switch 106 energizes the controllable valve 107, which opens the controllable valve 107, and the gas in the body 102 flows out, completing the replacement of the gas in the body 102. When the user completes the gas replacement, the vehicle 101 is in an unignited state, and the power supply module 104 stops supplying power to the control module 105. The control module 105 cannot operate due to the lack of power and cannot control the opening of the controllable electronic switch 106. The controllable electronic switch 106 cannot close to energize the controllable valve 107, and the power consumption of the gas replacement device 103 is zero, meeting the static power consumption requirements of the vehicle. When the vehicle 101 is in the ignition state, the power supply module 104 operates in the second power supply mode and supplies power to the control module 105 , so that the control module 105 is in the power-on state.

[0080] It should be noted that Figure 1It is only a structural schematic diagram of the gas replacement device provided in this application. It can be understood that in one specific embodiment, the gas filling inlet 113 and the gas outlet 114 can be different interfaces, and in another specific embodiment, the gas filling inlet 113 and the gas outlet 114 can be the same interface. This application does not limit its actual form, and in the specific application of the solution, it can be set according to actual needs.

[0081] In this embodiment, the gas replacement device 103 includes a power supply module 104, a control module 105, a controllable electronic switch 106, and a controllable valve 107 mounted on the body 102. This application allows the gas replacement process to be performed without a host computer, thus resolving the problem of poor gas replacement operation convenience in the prior art. In the gas replacement device 103, the power supply terminal g1 of the power supply module 104 is connected to the power input terminal a2 of the control module 105, and the controllable electronic switch 106 is connected between the power output terminal a1 of the control module 105 and the power supply terminal b1 of the controllable valve 107. When the vehicle 101 is in an unignited state and gas replacement is required, the power supply module 104 operates in a first power supply mode and supplies power to the control module 105, energizing the control module 105. While operating in the first power supply mode, the power supply module 104 also generates a closing command, which controls the controllable electronic switch 106 to be closed, causing the controllable valve 107 to open upon energization. This application eliminates the high-voltage power supply during the gas replacement process, preventing the vehicle from being in an unignited state. This addresses the safety issues associated with prior art gas replacement operations. When vehicle 101 is unignited and no gas replacement is required, power supply module 104 stops supplying power to control module 105. This approach eliminates the high static power consumption associated with prior art gas replacement operations.

[0082] The components included in the power supply module 105 in the first embodiment are explained below through the second embodiment.

[0083] The power supply module 105 includes an uncontrolled power supply unit 108 , a controllable power supply unit 109 and a switching unit 110 .

[0084] In the power supply module 105, the first end d1 of the switching unit 110 is connected to the output end e1 of the uncontrolled power supply unit 108, the second end d2 of the switching unit 110 is connected to the output end f1 of the controllable power supply unit 109, and the third end d3 of the switching unit 110 is connected to the power input end a2 of the control module 105.

[0085] The uncontrolled power supply unit 108 is used to connect with the control module 105 and supply power to the control module 105 when the vehicle 101 is in an unignition state and needs to replace the gas.

[0086] The controllable power supply unit 109 is used to connect to the control module 105 and supply power to the control module 105 when the vehicle 101 is in the ignition state. The controllable power supply unit 109 is also used to stop supplying power to the control module 105 when the vehicle 101 is in the unignition state and does not need to replace the gas.

[0087] The switching unit 110 is used to connect the uncontrolled power supply unit 108 to the control module 105 when the vehicle 101 is in an unignited state and needs to replace the gas. The switching unit 110 is also used to connect the controllable power supply unit 109 to the control module 105 when the vehicle 101 is in an ignition state and when the vehicle is in an unignited state and does not need to replace the gas.

[0088] Specifically, Figure 2 The schematic diagram of the structure of the gas replacement device provided in this application is as follows: Figure 2 As shown, when the user needs to perform gas replacement, the vehicle 101 does not need to be ignited. The user connects the uncontrolled power supply unit 108 to the control module 105 through the switching unit 110, and the uncontrolled power supply unit 108 supplies power to the control module 105. Figure 3 The schematic diagram of the structure of the gas replacement device provided in this application is as follows: Figure 3 As shown, when the vehicle 101 is in the ignition state, the vehicle 101 generates an enable signal and sends the enable signal to the controllable power supply unit 109. The user connects the controllable power supply unit 109 to the control module 105 through the switching unit 110. The controllable power supply unit 109 receives the enable signal and supplies power to the control module 105. When the vehicle 101 is in the unignition state and there is no need to replace the gas, the switching unit 110 connects the controllable power supply unit 109 to the control module 105. Since the vehicle 101 is in the unignition state, the vehicle 101 does not generate an enable signal, the controllable power supply unit 109 does not receive the enable signal, and stops supplying power to the control module 105.

[0089] In this embodiment, the power supply module 105 includes an uncontrolled power supply unit 108, a controllable power supply unit 109, and a switching unit 110. In the power supply module 105, a first terminal d1 of the switching unit 110 is connected to the output terminal e1 of the uncontrolled power supply unit 108, a second terminal d2 of the switching unit 110 is connected to the output terminal f1 of the controllable power supply unit 109, and a third terminal d3 of the switching unit 110 is connected to the power input terminal a2 of the control module 105. When the vehicle 101 is in an unignition state and requires gas replacement, the switching unit 110 connects the uncontrolled power supply unit 108 to the control module 105, supplying power to the control module 105. During the gas replacement process, the vehicle 101 is not in a high-voltage energized state, thereby resolving the safety issues associated with conventional gas replacement operations. When vehicle 101 is in the ignition state, switching unit 110 connects controllable power supply unit 109 to control module 105. Controllable power supply unit 109 receives an enable signal and supplies power to control module 105; the enable signal is generated when vehicle 101 is in the ignition state. When vehicle 101 is in the unignition state and no gas replacement is required, switching unit 110 connects controllable power supply unit 109 to control module 105. Controllable power supply unit 109 does not receive the enable signal and stops supplying power to control module 105. In this embodiment, switching unit 110 connects controllable power supply unit 109 to control module 105 or uncontrolled power supply unit 108 to control module 105. When vehicle 101 is in the unignition state and no gas replacement is required, power supply module 104 stops supplying power to control module 105, resolving the issue of high static power consumption associated with gas replacement operations in the prior art.

[0090] The components included in the power supply module 105 in the second embodiment are explained below through the third embodiment.

[0091] The power supply module 104 further includes a single-pole mechanical switch 111 , and the switching unit 110 includes a double-pole single-throw mechanical switch 112 .

[0092] The control terminal c1 of the controllable electronic switch 106 is connected to the control output terminal a4 of the control module 105 ; the double-pole single-throw mechanical switch 112 is linked to the single-pole mechanical switch 111 included in the power supply module 104 .

[0093] The single-pole mechanical switch 111 is configured to close when the uncontrolled power supply unit 108 is connected to the control module 105. When the single-pole mechanical switch 111 is closed, the single-pole mechanical switch 111 is connected to the control input a3 of the control module 105, and the control output a4 of the control module outputs an electrical signal. The electrical signal output by the control output a4 of the control module controls the controllable electronic switch 106 to be in a closed state. Specifically, the single-pole mechanical switch 111 is configured to connect to the control input a3 of the control module 105 when the double-pole single-throw mechanical switch 112 connects the uncontrolled power supply unit 108 to the control module 105.

[0094] The single-pole mechanical switch 111 is also used to disconnect the single-pole mechanical switch 111 from the control input terminal a3 of the control module 105 when the double-pole single-throw mechanical switch 112 connects the controllable power supply unit 109 to the control module 105 .

[0095] The double-pole mechanical switch 112 is used to connect the uncontrolled power supply unit 108 to the control module 105 . The double-pole mechanical switch 112 is also used to connect the controllable power supply unit 109 to the control module 105 .

[0096] Specifically, if Figure 2 As shown, when the user needs to replace the gas, there is no need to ignite the vehicle 101. The user throws the double-pole single-throw mechanical switch 112, the uncontrolled power supply unit 108 is connected to the control module 105, the double-pole single-throw mechanical switch 112 is linked with the single-pole mechanical switch 111, the single-pole mechanical switch 111 is closed, and the single-pole mechanical switch 111 is connected to the control input terminal a3 of the control module 105. The control output terminal a4 of the control module 105 outputs an electrical signal. The electrical signal output by the control output terminal a4 of the control module controls the controllable electronic switch 106 to be in a closed state, and the controllable valve 107 opens after power is supplied. Figure 3 As shown, when the vehicle 101 is in an unignited state and does not need to replace the gas and when the vehicle 101 is in an ignition state, the user does not throw the double-pole single-throw mechanical switch 112, the uncontrolled power supply unit 108 is not connected to the control module 105, but the controllable power supply unit 109 is connected to the control module 105. When the double-pole single-throw mechanical switch 112 connects the controllable power supply unit 109 to the control module 105, the double-pole single-throw mechanical switch 112 is linked to the single-pole mechanical switch 111, the single-pole mechanical switch 111 is not closed, and the single-pole mechanical switch 111 is disconnected from the control input terminal a3 of the control module 105.

[0097] In this embodiment, the power supply module 104 further includes a single-pole mechanical switch 111, and the switching unit 110 includes a double-pole, single-throw mechanical switch 112. The control terminal c1 of the controllable electronic switch 106 is connected to the control output terminal a4 of the control module 105; the double-pole, single-throw mechanical switch 112 is linked to the single-pole mechanical switch 111 included in the power supply module 104. When a user needs to perform gas replacement, without igniting the vehicle 101, the user flips the double-pole, single-throw mechanical switch 112, connecting the uncontrolled power supply unit 108 to the control module 105. The double-pole, single-throw mechanical switch 112 is linked to the single-pole mechanical switch 111, closing the single-pole mechanical switch 111, and connecting it to the control input terminal a3 of the control module 105. The control output terminal a4 of the control module 105 outputs an electrical signal. The electrical signal output from the control output terminal a4 controls the controllable electronic switch 106 to be in a closed state, and the controllable valve 107 opens upon powering on. When the vehicle 101 is in an unignited state and does not require gas replacement and when the vehicle 101 is in an ignition state, the user does not throw the double-pole single-throw mechanical switch 112, the uncontrolled power supply unit 108 is not connected to the control module 105, but the controllable power supply unit 109 is connected to the control module 105. When the double-pole single-throw mechanical switch 112 connects the controllable power supply unit 109 to the control module 105, the double-pole single-throw mechanical switch 112 is linked to the single-pole mechanical switch 111, the single-pole mechanical switch 111 is not closed, and the single-pole mechanical switch 111 is disconnected from the control input terminal a3 of the control module 105. In this embodiment, the user can use the double-pole single-throw mechanical switch 112 to handle the connection relationship between the control module 105 and the controllable power supply unit 109 or the connection relationship between the control module 105 and the uncontrolled power supply unit 108. By utilizing the linkage effect of the single-pole mechanical switch 111 and the double-pole single-throw mechanical switch 112, the on-off of the line between the control module 105 and the single-pole mechanical switch 111 can be handled, and then the opening and closing of the controllable electronic switch 106 can be controlled, thereby solving the problem of poor convenience of the gas replacement device 103 during the gas replacement operation.
