DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0039] First, an embodiment of the present application provides a gas supply system.

[0040] Figure 1 This is a schematic diagram of the structure of an embodiment of the gas supply system provided in the embodiment of the present application. Figure 1 As shown, the air supply system 11 includes an air compressor 111 and a gas transmission structure 113. The air compressor 111, also known as a gas compressor, is used to suck gas from one end and discharge it from the other end after pressurizing the gas. In other words, the air compressor 111 is used to provide high-pressure gas. The gas transmission structure 113 is connected to the air compressor 111, and the air compressor 111 is used to provide high-pressure gas to the gas transmission structure 113. The gas transmission structure 113 is used to communicate with the air springs 12 of the air suspension system of the vehicle 10 to transmit the gas provided by the air compressor 111 to the air springs 12 of the air suspension system, so that the air springs 12 have a vibration reduction and buffering effect, and realize the raising or lowering of the vehicle body.

[0041] In some embodiments, the gas transmission structure 113 can also be used to connect with the airbag 13 of the seat wing of the vehicle 10 to transmit the gas provided by the air compressor 111 to the airbag 13 of the seat wing to adjust the size of the airbag 13, so that the seat wing of the vehicle 10 can realize the active support function for the occupants and improve the riding experience of the occupants.

[0042] The air supply system 11 provided in the embodiment of the present application connects a gas transmission structure 113 with an air compressor 111. The gas transmission structure 113 is used to communicate with the air springs 12 of the air suspension system of the vehicle 10 and the airbags 13 of the seat wing, so as to transmit gas provided by the air compressor 111 to the air springs 12 of the air suspension system and the airbags 13 of the seat wing. Therefore, the air springs 12 of the air suspension system of the vehicle 10 and the airbags 13 of the seat wing can share the same air compressor 111, eliminating the need to provide a separate air compressor 111 for each airbag 13 of the seat wing. This helps reduce the number of air compressors 111 in the air supply system 11, thereby reducing the cost of the air supply system 11 and, in turn, the overall cost of the vehicle 10. Furthermore, it can save space within the vehicle 10 for installing the air compressor 111, making the structure of the vehicle 10 more compact, or increasing the remaining space within the vehicle 10 while maintaining the overall size of the vehicle 10.

[0043] It should be noted that the gas transmission structure 113 can directly transmit the gas provided by the air compressor 111 to the air springs 12 of the air suspension system and the air bags 13 of the seat side wings, or the gas transmission structure 113 can also store the gas provided by the air compressor 111. When the air springs 12 of the air suspension system and the air bags 13 of the seat side wings need to be inflated, the gas transmission structure 113 will then transmit the stored gas to the air springs 12 of the air suspension system and the air bags 13 of the seat side wings.

[0044] In some embodiments, the gas transmission structure 113 may include a first transmission assembly 1131 and a second transmission assembly 1137. The first transmission assembly 1131 and the second transmission assembly 1137 are respectively connected to the air compressor 111 and are respectively used to transmit the gas provided by the air compressor 111. The first transmission assembly 1131 is used to communicate with the air spring 12 to transmit the gas provided by the air compressor 111 to the air spring 12 of the air suspension system. The second transmission assembly 1137 is used to communicate with the airbag 13 to transmit the gas provided by the air compressor 111 to the airbag 13 of the seat side.

[0045] The gas provided by the air compressor 111 is transmitted to the air spring 12 of the air suspension system through the first transmission component 1131, and the gas provided by the air compressor 111 is transmitted to the air bag 13 of the seat side wing through the second transmission component 1137. This enables the inflation of the air spring 12 of the air suspension system and the air bag 13 of the seat side wing to be relatively independent, thereby reducing the mutual influence between the air spring 12 and the air bag 13 during the inflation process.

[0046] It should be noted that the first transmission component 1131 and the second transmission component 1137 can be completely independent of each other and connected to the air compressor 111, that is, the air compressor 111 inflates the air spring 12 of the air suspension system through the first transmission component 1131 alone, and inflates the air bag 13 of the seat wing alone through the second transmission component 1137. Alternatively, the first transmission component 1131 and the second transmission component 1137 can also be connected to each other, or the two share part of the gas transmission pipeline. For example: the air compressor 111 provides gas to the first transmission component 1131, the first transmission component 1131 is used to transmit the gas to the air spring 12 of the air suspension system and the second transmission component 1137, the second transmission component 1137 receives the gas transmitted by the first transmission component 1131, and transmits the gas to the air bag 13 of the seat wing.

[0047] In some embodiments, as Figure 1 As shown, the first transmission assembly 1131 may include a first control valve mechanism 1132 and a first air storage tank 1135. One end of the air compressor 111 and the first air storage tank 1135 are respectively connected to the first control valve mechanism 1132. When the air compressor 111 is running, the other end of the air compressor 111 sucks in gas, pressurizes the sucked gas, and discharges it from one end of the air compressor 111.

[0048] The first control valve mechanism 1132 is used to communicate with the air spring 12 , and the first control valve mechanism 1132 is used to control the connection and closing among one end of the air compressor 111 , the first air storage tank 1135 and the air spring 12 .

[0049] Thus, when the first control valve mechanism 1132 controls the connection between one end of the air compressor 111 and the air spring 12 of the air suspension system, the air compressor 111 can directly inflate the air spring 12 of the air suspension system. When the first control valve mechanism 1132 controls the connection between one end of the air compressor 111 and the first air tank 1135, the air compressor 111 can inflate the first air tank 1135 to store high-pressure gas in the first air tank 1135.

[0050] When the air spring 12 of the air suspension system needs to be inflated quickly, the first control valve mechanism 1132 can be used to control the connection between the first air tank 1135 and the air spring 12 of the air suspension system, so that the first air tank 1135 can quickly fill the air spring 12 of the air suspension system with high-pressure gas.

[0051] The first gas tank 1135 can also supply the high-pressure gas stored therein to the first transmission assembly 1131, which transmits the high-pressure gas to the airbag 13 in the seat wing. For example, the second transmission assembly 1137 can be connected to one end of the air compressor 111, thereby connecting the second transmission assembly 1137 to the first gas tank 1135 of the first transmission assembly 1131. Alternatively, the second transmission assembly 1137 can be connected to the other end of the air compressor 111, thereby connecting the second transmission assembly 1137 to the first gas tank 1135 of the first transmission assembly 1131 through the air compressor 111. Furthermore, the second transmission assembly 1137 can be directly connected to the first gas tank 1135, thereby supplying the high-pressure gas stored in the first gas tank 1135 to the first transmission assembly 1131.

[0052] In some embodiments, the first control valve mechanism 1132 includes a first control valve 1133 and a second control valve 1134. One end of the first control valve 1133 and the second control valve 1134 are respectively connected to one end of the air compressor 111. The other end of the first control valve 1133 is used to communicate with the air spring 12 of the air suspension system. The other end of the second control valve 1134 is used to communicate with the first air tank 1135. Thus, by controlling the opening and closing of the first control valve 1133, the connection between one end of the air compressor 111 and the air spring 12 of the air suspension system can be achieved. By controlling the opening and closing of the second control valve 1134, the connection between one end of the air compressor 111 and the first air tank 1135 can be controlled. When both the first control valve 1133 and the second control valve 1134 are opened, the first air tank 1135 is connected to the air spring 12 of the air suspension system.

[0053] The first control valve 1133 and the second control valve 1134 may be solenoid valves to facilitate control of the first control valve 1133 and the second control valve 1134. Of course, the first control valve 1133 and the second control valve 1134 may also be pneumatic valves or other types of control valves, which are not limited here.

[0054] In some embodiments, as Figure 1 As shown, first transmission assembly 1131 may further include a drying tank 1136 connected in series between one end of air compressor 111 and first control valve mechanism 1132. One end of drying tank 1136 communicates with one end of air compressor 111, while the other end communicates with first control valve mechanism 1132. Specifically, one end of first control valve 1133 and one end of second control valve 1134 are respectively connected to the other end of drying tank 1136. Thus, drying tank 1136 can dry the gas transmitted from one end of air compressor 111 to first control valve mechanism 1132, thereby improving the service life of the air suspension system.

[0055] In some embodiments, as Figure 1 As shown, the second transmission assembly 1137 can include a second gas tank 1138, the inlet of which is in communication with the first transmission assembly 1131, and the outlet of which is in communication with the airbag 13. Thus, the gas exhausted from the air compressor 111 can be transmitted to the second gas tank 1138 for storage via the first transmission assembly 1131. When the airbag 13 in the seat wing needs to be inflated, the second gas tank 1138 can be directly used to transmit gas to the airbag 13 in the seat wing, making operation more convenient.

[0056] Among them, the first transmission component 1131 can be connected to one end of the air compressor 111, and the inlet of the second air tank 1138 can be connected to the other end of the air compressor 111, so that the inlet of the second air tank 1138 is connected to the first transmission component 1131 through the air compressor 111.

[0057] Alternatively, the first transmission assembly 1131 may be connected to one end of the air compressor 111, and the inlet of the second gas tank 1138 may be connected to one end of the air compressor 111, thereby directly connecting the inlet of the second gas tank 1138 to the first transmission assembly 1131. In this case, the air compressor 111 may directly transmit gas to the second gas tank 1138, or the first transmission assembly 1131 may transmit stored gas to the second gas tank 1138.

[0058] Continue to refer to Figure 1, the air supply system 11 may include a second control valve mechanism 114 for communicating with the outside world. The other end of the air compressor 111 and the inlet of the second air storage tank 1138 are respectively connected to the second control valve mechanism 114. The second control valve mechanism 114 is used to control the connection between the other end of the air compressor 111 and the outside world, and to control the connection and closing between the other end of the air compressor 111 and the inlet of the second air storage tank 1138. The second control valve mechanism 114 can facilitate switching of the connection between the other end of the air compressor 111 and the outside world and the inlet of the second air storage tank 1138.

[0059] When the second control valve mechanism 114 controls the connection between the other end of the air compressor 111 and the outside world, the air compressor 111 can draw in and compress air from the outside world, and then transmit it to the first transmission assembly 1131 through the gas transmission structure 113. When the second control valve mechanism 114 controls the connection between the other end of the air compressor 111 and the outside world to be closed, and controls the other end of the air compressor 111 to be connected to the inlet of the second gas storage tank 1138, the second transmission assembly 1137 can transmit high-pressure gas to the second gas storage tank 1138 through the air compressor 111.

[0060] In some embodiments, the second control valve mechanism 114 can include a multi-way valve 1141, which includes a first interface 1142, a second interface 1143 and an air inlet 1144 that are interconnected. The first interface 1142 is connected to the other end of the air compressor 111, the second interface 1143 is connected to the inlet of the second air tank 1138, and the air inlet 1144 is used to connect with the outside world, so that the outside world and the inlet of the second air tank 1138 are respectively connected to the other end of the air compressor 111.

[0061] A first one-way valve 1146 is provided at the second port 1143 of the multi-way valve 1141. The outlet of the first one-way valve 1146 is connected to the inlet of the second gas tank 1138. Thus, the first one-way valve 1146 enables communication and closure between the inlet of the second gas tank 1138 and the other end of the air compressor 111. When the air pressure at the other end of the air compressor 111 exceeds the air pressure within the second gas tank 1138 by a certain value, the first one-way valve 1146 opens, connecting the other end of the air compressor 111 with the inlet of the second gas tank 1138, allowing the high-pressure gas stored in the first transmission assembly 1131 to be transmitted through the air compressor 111 to the second gas tank 1138. Otherwise, the first one-way valve 1146 remains closed to prevent the gas within the second gas tank 1138 from flowing back into the air compressor 111.

[0062] In addition, a third control valve 1147 is provided at the air inlet 1144 of the multi-way valve 1141. This third control valve 1147 is used to control the opening and closing of the third port. Thus, when the high-pressure gas stored in the first transmission assembly 1131 is transferred to the second air storage tank 1138 via the air compressor 111, the third control valve 1147 can be kept closed to prevent the high-pressure gas stored in the first transmission assembly 1131 from leaking to the outside world through the air inlet 1144. When the air compressor 111 needs to draw in and compress air from the outside world, the third control valve 1147 can be controlled to open.

[0063] The third control valve 1147 can be a second one-way valve, the inlet of which is connected to the outside world, so that the gas at the air inlet 1144 can only enter the multi-way valve 1141 from the outside world, and cannot leak out of the multi-way valve 1141 to the outside world. This has a simple structure and low cost. Of course, the third control valve 1147 can also be a solenoid valve, a pneumatic valve, etc., and the specific configuration can be based on actual needs.

[0064] In some embodiments, the multi-way valve 1141 may further include an exhaust port 1145 connected to the first interface 1142, and a fourth control valve 1148 is provided at the exhaust port 1145. The fourth control valve 1148 may be a solenoid valve, a pneumatic valve, etc., which are not limited here. When the fourth control valve 1148 is opened, the other end of the air compressor 111 can be connected to the outside world through the exhaust port 1145, so that the air spring 12 of the air suspension system can be connected to the outside world through the exhaust port 1145 of the air compressor 111 and the multi-way valve 1141, so that the gas in the air spring 12 can be quickly discharged to the outside world through the exhaust port 1145 of the air compressor 111 and the multi-way valve 1141.

[0065] The fourth control valve 1148 can be a normally open control valve. It is understood that due to the high humidity of the gas discharged from the air spring 12 of the air suspension system, the valve core of the fourth control valve 1148 is prone to freezing in low-temperature environments, resulting in the fourth control valve 1148 being unable to open normally, thereby affecting the normal exhaust of the air spring 12 of the air suspension system. By making the fourth control valve 1148 a normally open control valve, that is, the fourth control valve 1148 is in an open state in a normal state or an untriggered state, the fourth control valve 1148 can be prevented from being unable to open due to the valve core freezing, allowing the air spring 12 of the air suspension system to maintain good intake and exhaust functions, which is conducive to maintaining the operating stability of the air spring 12 of the air suspension system.

[0066] In some embodiments, the second transmission assembly 1137 may further include a pressure-limiting valve 1139. The inlet of the pressure-limiting valve 1139 communicates with the outlet of the second gas tank 1138, and the outlet of the pressure-limiting valve 1139 communicates with the winglet airbag 13. Thus, the pressure of the gas transmitted from the second gas tank 1138 to the winglet airbag 13 can be controlled via the pressure-limiting valve 1139, thereby achieving precise control over the size of the winglet airbag 13.

[0067] In some embodiments, as Figure 1 As shown, the air supply system 11 may further include a pressure relief valve 112, which is arranged in parallel with the air compressor 111. The pressure relief valve 112 can limit the pressure difference between the other end and the one end of the air compressor 111. When the air pressure at one end of the air compressor 111 exceeds the air pressure at the other end by a certain value, the gas at the other end of the air compressor 111 can quickly flow through the pressure relief valve 112 to the other end of the air compressor 111, thereby improving the exhaust efficiency and providing a certain degree of protection for the air compressor 111.

[0068] In some embodiments, as Figure 1 As shown, the gas supply system 11 may further include a pressure sensor 117 , which is connected to the inlet or outlet of the second gas storage tank 1138 , so as to detect the gas pressure intensity in the second gas storage tank 1138 .

[0069] In an embodiment of the present application, the multi-way valve 1141, the third control valve 1147, the first one-way valve 1146 and the fourth control valve 1148 can be integrated into a second control valve mechanism 114 to improve the structural compactness of the air supply system 11, which is conducive to reducing the overall volume of the multi-way valve 1141, the third control valve 1147, the first one-way valve 1146 and the fourth control valve 1148.

[0070] The various operating modes of the gas supply system 11 are described in detail below.

[0071] 1. Inflation of the air spring 12 of the air suspension system.

[0072] When the air spring 12 of the air suspension system needs to be inflated, the first control valve 1133 is controlled to open, and the air compressor 111 is turned on, such as Figure 1 As shown by the middle arrow, external gas can be sucked into the multi-way valve 1141 from the air inlet 1144 and the exhaust port 1145 of the multi-way valve 1141, compressed by the air compressor 111, dried by the drying tank 1136 of the first transmission component 1131, and then transmitted to the air spring 12 of the air suspension system through the first control valve 1133.

[0073] When the air compressor 111 does not inflate the air spring 12 of the air suspension system quickly enough, the second control valve 1134 can be opened to allow the gas in the first air tank 1135 to pass through the second control valve 1134 and the first control valve 1133 and then be transmitted to the air spring 12 of the air suspension system, so as to achieve rapid inflation of the air spring 12.

[0074] The gas in the first gas storage tank 1135 may be gas previously charged by the air compressor 111. The specific method of charging is as follows: the first control valve 1133 is controlled to be closed, the second control valve 1134 is controlled to be opened, and then the air compressor 111 is turned on. External gas is drawn into the multi-way valve 1141 through the air inlet 1144 and the exhaust port 1145 of the multi-way valve 1141. After being compressed by the air compressor 111, the gas is dried by the drying tank 1136 of the first transmission assembly 1131. The gas is then transferred to the first gas storage tank 1135 through the second control valve 1134 to charge the first gas storage tank 1135.

[0075] 2. Rapid exhaust of the air spring 12 of the air suspension system.

[0076] When the air in the air spring 12 of the air suspension system needs to be quickly discharged, the first control valve 1133 can be controlled to open and the second control valve 1134 can be closed. Figure 2 As indicated by the middle arrow, the gas within the air spring 12 of the air suspension system passes through the first control valve 1133, the drying tank 1136, and the air compressor 111, and is then discharged through the exhaust port 1145 of the multi-way valve 1141. Furthermore, when the pressure at one end of the air compressor 111 exceeds the pressure at the other end by a certain value, the gas within the air spring 12, after passing through the first control valve 1133 and the drying tank 1136, bypasses the air compressor 111, is transferred through the pressure relief valve 112 to the multi-way valve 1141, and is discharged through the exhaust port 1145 of the multi-way valve 1141.

[0077] 3. Inflation of the second gas storage tank 1138.

[0078] When the second gas storage tank 1138 needs to be inflated, the fourth control valve 1148 is controlled to be closed, and at least one of the first control valve 1133 and the second control valve 1134 is controlled to be opened. Figure 3 As shown by the middle arrow, at least one of the air spring 12 and the first air tank 1135 discharges high-pressure gas. The high-pressure gas passes through the drying tank 1136, the air compressor 111 and / or the pressure relief valve 112, and the multi-way valve 1141, and is then transmitted from the second interface 1143 of the multi-way valve 1141 through the first one-way valve 1146 to the second air tank 1138 to complete the inflation operation of the second air tank 1138.

[0079] 4. The airbags 13 on the seat wing are inflated.

[0080] When the airbag 13 of the seat wing needs to be inflated, the pressure limiting valve 1139 is opened, as shown in FIG. Figure 4 As shown by the middle arrow, the high-pressure gas in the second gas tank 1138 is transmitted to the airbag 13 .

[0081] In other embodiments, Figure 5 As shown, the second transmission assembly 1137 can further include a first one-way valve 1146, the inlet of which is connected to the other end of the air compressor 111, and the outlet of which is connected to the inlet of the second gas storage tank 1138. Thus, the first one-way valve 1146 can be used to connect and close the inlet of the second gas storage tank 1138 to the other end of the air compressor 111. When the air pressure at the other end of the air compressor 111 exceeds the air pressure within the second gas storage tank 1138 by a certain value, the first one-way valve 1146 is opened, connecting the other end of the air compressor 111 with the inlet of the second gas storage tank 1138, thereby transferring the high-pressure gas stored in the first transmission assembly 1131 to the second gas storage tank 1138 via the air compressor 111. Otherwise, the first one-way valve 1146 remains closed to prevent the gas within the second gas storage tank 1138 from flowing back into the air compressor 111.

[0082] The inlet of the first one-way valve 1146 and the other end of the air compressor 111 , as well as the outlet of the first one-way valve 1146 and the inlet of the second air storage tank 1138 , can be connected through independent pipelines.

[0083] In other embodiments, Figure 5 As shown, the air supply system 11 may further include a second one-way valve, the inlet of the second one-way valve being connected to the outside world, and the outlet of the second one-way valve being connected to the other end of the air compressor 111. This allows the gas at the air inlet 1144 to only enter the multi-way valve 1141 from the outside world, and not to leak out of the multi-way valve 1141 to the outside world. The outlet of the second one-way valve and the other end of the air compressor 111 may be connected via an independent pipeline.

[0084] In other embodiments, Figure 5 As shown, the air supply system 11 further includes a fourth control valve 1148, one end of which is connected to the other end of the air compressor 111, and the other end of which is connected to the outside world. Fourth control valve 1148 is a normally open control valve, thereby preventing the fourth control valve 1148 from being unable to open due to icing of the valve core. This allows the air springs 12 of the air suspension system to maintain good air intake and exhaust functions, which is conducive to maintaining the operating stability of the air springs 12 of the air suspension system. One end of the fourth control valve 1148 can be connected to the other end of the air compressor 111 via an independent pipeline.

[0085] In some embodiments, as Figure 1 As shown, the air supply system 11 may further include a first air filter 115 , which is connected to the inlet of the second one-way valve, so as to filter the air entering the first one-way valve 1146 from the outside.

[0086] In addition, the air supply system 11 may further include a second air filter 116, which is connected to the other end of the fourth control valve 1148 to filter the air entering the fourth control valve 1148 from the outside. Moreover, when the exhaust port 1145 of the multi-way valve 1141 is exhausted, the second air filter 116 can also comb the exhausted gas to reduce the turbulent noise of the airflow.
