[0002] Gas fuel vehicles drive the vehicle by burning gas materials. Among them, gas fuel vehicles are divided into two types: liquefied petroleum gas vehicles and compressed natural gas vehicles. Compressed natural gas vehicles reduce the high-pressure natural gas in the gas cylinder to the gas pressure required by the engine through a pressure reducing valve. When the pressure reducing valve is working, the gas expands and absorbs heat seriously, causing the temperature of the pressure reducing valve itself to drop.

[0039] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0042] In order to heat the pressure reducing valve to prevent the pressure reducing valve from failing to work due to too low a temperature, an embodiment of the present invention provides a heating device for a vehicle pressure reducing valve. Figure 1 The schematic diagram of the structure of a vehicle pressure reducing valve heating device provided by an embodiment of the present invention. Figure 1 As shown in , the device includes:

[0043] The processing module 101, the temperature acquisition module 102, the first heating circuit 103 and the second heating circuit 104. The second heating circuit 104 is provided with a heat exchange module 105. The device is used to heat the pressure reducing valve 106.

[0044] The temperature collection module 102 is disposed in the vehicle cockpit and is used to collect the temperature of the vehicle cockpit.

[0045] The first heating circuit 103 is connected to the vehicle engine cooling water circuit 107. When the first heating circuit 103 is turned on, the first heating circuit 103 heats the pressure reducing valve based on the vehicle engine cooling water circuit 107. Specifically, the vehicle engine cooling water circuit 107 is specifically provided with an engine 108 and a second water pump 109. The second water pump 109 is used to drive the coolant or water in the vehicle engine cooling water circuit 107 and the pressure reducing valve 106 to circulate.

[0046] The second heating circuit 104 is connected in parallel with the first heating circuit 103. When the second heating circuit 104 is turned on, the second heating circuit 104 heats the pressure reducing valve 106 based on the heat exchange module 105 absorbing the heat in the vehicle cockpit. The heat exchange module 105 is arranged in the vehicle cockpit, so as to absorb the heat in the vehicle cockpit.

[0047] The processing module 101 is connected to the temperature acquisition module 102, and is used to obtain the vehicle cockpit temperature acquired by the temperature acquisition module 102, and control the conduction and disconnection of the first heating circuit 103 and the second heating circuit 104 based on the vehicle cockpit temperature. The processing module 101 can be specifically implemented as an automotive electronic control unit (ECU).

[0048] In some embodiments, the second heating circuit 104 heats the pressure reducing valve 106 by water bath heating. Then the heat exchange module 105 can be specifically implemented in the form of a radiator. In order to allow water circulation between the second heating circuit 104 and the pressure reducing valve 106, a first water pump can be provided in the second heating circuit 104. The first water pump can be implemented in the form of a mechanical water pump or an electronic water pump. The heat exchange module 105 is specifically provided with a water outlet and a water inlet. The water outlet of the heat exchange module 105 is connected to the water inlet of the pressure reducing valve 106 through the first heat conduction channel. The water inlet of the heat exchange module 105 is connected to the water outlet of the pressure reducing valve 106 through the second heat conduction channel.

[0049] When the pressure reducing valve 106 is heated based on the second heating circuit 104, the processing module 101 controls the second heating circuit 104 to be turned on, and controls the first water pump to be turned on. The first water pump drives the liquid (water, coolant or other solvent with good thermal conductivity) in the first heat conduction channel and the second heat conduction channel to circulate. Specifically, the heat exchange module 105 in the second heating circuit 104 absorbs the heat in the vehicle cockpit and transfers the heat to the water flowing through the heat exchange module 105. Therefore, the water flowing in the first heat conduction channel after passing through the heat exchange module 105 is hot water, which is used to heat the pressure reducing valve 106. When the heat of the water flowing into the pressure reducing valve 106 is absorbed by the pressure reducing valve 106, cold water flows out from the water outlet of the pressure reducing valve 106. The cold water re-enters the heat exchange module 105 through the second heat conduction channel and the water inlet of the heat exchange module 105. Then, a blower or other equipment can blow air to the second heat conduction channel portion between the water outlet of the pressure reducing valve 106 and the water inlet of the heat exchange module 105, thereby obtaining cold air. The vehicle cockpit is cooled based on the cold wind. This method can not only solve the heating problem of the pressure reducing valve, but also solve the defect that commercial vehicles of gas fuel vehicles have no air conditioning and can only be cooled by opening windows in summer, thereby reducing energy consumption and costs while increasing the driving experience of the driver.

[0050] In some embodiments, the present invention provides another schematic diagram of a heating device for a vehicle pressure reducing valve. Figure 2As shown in , a first electromagnetic valve 110 is provided in the first heating circuit 103, and a second electromagnetic valve 111 is provided in the second heating circuit 104. When the first electromagnetic valve 110 is opened, the first heating circuit 103 is turned on. When the first electromagnetic valve 110 is closed, the first heating circuit 103 is turned off. When the second electromagnetic valve 111 is opened, the second heating circuit 104 is turned on. When the second electromagnetic valve 111 is closed, the second heating circuit 104 is turned off. Therefore, the processing module 101 can control the conduction and disconnection of the first heating circuit 103 by controlling the opening and closing of the first electromagnetic valve 110. And, the processing module 101 can control the conduction and disconnection of the second heating circuit 104 by controlling the opening and closing of the second electromagnetic valve 111.

[0051] The vehicle pressure reducing valve heating device provided by the embodiment of the present invention heats the pressure reducing valve by absorbing the temperature in the vehicle cockpit when the temperature in the vehicle cockpit is high, and uses the circulating water heated by the pressure reducing valve to cool the vehicle cockpit, thereby solving the problem that commercial gas fuel vehicles do not have air conditioning refrigeration in summer. The vehicle pressure reducing valve heating device provided by the embodiment of the present invention is easy to use, and there is no need to consider the problem of energy consumption caused by air conditioning, thereby achieving effective energy utilization and cost saving.

[0052] Corresponding to the above-mentioned vehicle pressure reducing valve heating device, an embodiment of the present invention provides a corresponding vehicle pressure reducing valve heating method. Figure 3 The flowchart of a method for heating a vehicle pressure reducing valve provided by an embodiment of the present invention is as follows. Figure 3 As shown in , the method includes:

[0053] Step 301, obtaining the vehicle cabin temperature.

[0054] The temperature of the vehicle cockpit can be collected by the temperature collection module arranged in the vehicle cockpit, thereby obtaining the vehicle cockpit temperature.

[0055] Step 302, determining whether the vehicle cabin temperature is greater than a first threshold.

[0056] The temperature acquisition module transmits the acquired vehicle cabin temperature to the ECU. The ECU determines whether the vehicle cabin temperature is greater than a set first threshold.

[0057] Step 303: If the cabin temperature is greater than a first threshold, the heat exchange module absorbs the heat of the vehicle cabin and performs water bath heating on the pressure reducing valve.

[0058] When the cockpit temperature is greater than the first threshold, it means that the temperature in the cockpit is high. The heat exchange module absorbs the heat in the cockpit to heat the pressure reducing valve, which can reduce the temperature in the cockpit. Then, the vehicle cockpit is cooled based on the circulating water after the pressure reducing valve is heated in a water bath. Specifically, the ECU can control the above-mentioned first solenoid valve to close and the second solenoid valve to open, so that the first heating circuit is disconnected and the second heating circuit is turned on, thereby heating the pressure reducing valve based on the second heating circuit. When the hot water used to heat the pressure reducing valve flows through the pressure reducing valve, the heat in the water is absorbed by the pressure reducing valve, and the temperature of the circulating water after passing through the pressure reducing valve becomes lower. The cockpit is further cooled based on the low-temperature water, thereby achieving the same effect as air conditioning cooling.

[0059] In some embodiments, if the cockpit temperature is less than or equal to the first threshold, it means that the cockpit temperature is low and insufficient to complete the heating of the pressure reducing valve. At this time, the pressure reducing valve can be heated based on the vehicle engine cooling circulation water circuit. Specifically, the ECU can control the first solenoid valve to open and the second solenoid valve to close, so that the first heating circuit is turned on and the second heating circuit is turned off. The pressure reducing valve is then heated based on the first heating circuit. In the first heating circuit, the vehicle engine cooling water circuit cools the engine by water cooling. After the cooling water passes through the engine, it absorbs the heat of the engine and becomes hot water. Therefore, this part of the hot water in the engine cooling water circuit circulation can be circulated to the pressure reducing valve to heat the pressure reducing valve.
