DETAILED DESCRIPTION

[0025] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connecting" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] The vehicle's suspension system is a connector between the vehicle's powertrain and body. Its main function is to support the powertrain, reduce the impact of the powertrain's vibration on the vehicle, and limit the amount of powertrain vibration. It plays a very important role in the vehicle's NVH performance (NoiseVibration and AcousticRoughness).

[0028] Since the engine itself is an internal vibration source and is also subject to various external vibration interferences, which can cause damage to components and ride discomfort, setting up a suspension system can minimize the vibration transmitted from the engine to the support system.

[0029] The ability of the suspension system to successfully control vibration mainly depends on its structural type, geometric position, and the structure, stiffness and damping characteristics of the suspension pad. Determining a reasonable suspension system is a rather complicated task. It must meet a series of static and dynamic performance requirements and is subject to various conditions, which greatly increase the difficulty of design.

[0030] Generally speaking, the following requirements are imposed on the suspension system:

[0031] (1) It can withstand dynamic and static loads under all working conditions, and keep the displacement of the engine assembly in all directions within an acceptable range without interfering with other parts on the chassis. At the same time, no parts will be damaged before the engine is overhauled;

[0032] (2) It can fully isolate the transmission of vibration generated by the engine to the frame and cab, reducing vibration noise;

[0033] (3) It can fully isolate the vibration caused by uneven road surface and transmitted to the engine through the suspension, reduce vibration noise, and ensure that the bending at the connection between the engine body and the flywheel housing does not exceed the allowable value of the engine manufacturer.

[0034] The suspension system is installed in the vehicle's engine compartment. When the vehicle collides violently or other circumstances cause a fire, the various liquids in the engine compartment are easily burned after being exposed to high temperatures, generating toxic gases and aggravating the combustion, affecting the life safety of the passengers in the vehicle.

[0035] Based on this, the applicant found that if a suspension system with a fire extinguishing function could be provided and installed in the cabin, then when a fire occurs in the cabin, the suspension system can play a fire extinguishing role to avoid a fire in the cabin that would affect the safety of the vehicle and its occupants.

[0036] Based on this, see Figure 1 and Figure 2 , the present application provides a suspension system, comprising:

[0037] The suspension assembly 1 is provided with a receiving chamber 121 for receiving the fire extinguishing gas;

[0038] The air guide tube 2 includes an air inlet end 23 and an air outlet end 24. The air inlet end 23 passes through the suspension assembly 1 and extends into the accommodating cavity 121. The air outlet end 24 is located outside the suspension assembly 1.

[0039] The fully enclosed thermistor 3 is located in the guide tube 2. There is no gap between the outer wall of the thermistor 3 and the inner wall of the guide tube 2 so that the gas outlet end 24 is not connected to the accommodating cavity 121. It is configured that when the temperature is greater than or equal to the preset temperature, the volume of the thermistor 3 is deformed to connect the gas outlet end 24 with the accommodating cavity 121, so that the fire extinguishing gas in the accommodating cavity 121 flows out from the gas outlet end 24.

[0040] Specifically, the accommodating chamber 121 may contain high-pressure fire extinguishing gas, which may be heptafluoropropane (HFC-227ea), carbon dioxide, nitrogen, argon, or IG541 mixed gas extinguishing agent (composed of nitrogen, argon, and carbon dioxide).

[0041] The fully enclosed thermistor 3 is located in the guide tube 2, and there is no gap between the outer wall of the thermistor 3 and the inner wall of the guide tube 2 so that the gas outlet end 24 is not connected to the accommodating cavity 121. Exemplarily, the outer wall of the thermistor 3 and the inner wall of the guide tube 2 can be connected by bonding so that there is no gap between the outer wall of the thermistor 3 and the inner wall of the guide tube 2. In this way, the thermistor 3 successfully blocks the high-pressure gas in the accommodating cavity 121, preventing the high-pressure fire-extinguishing gas in the accommodating cavity 121 from flowing out from the gas outlet end 24.

[0042] When the temperature is greater than or equal to the preset temperature, the volume of the thermistor 3 is deformed so that the gas outlet 24 is connected to the accommodating cavity 121. Exemplarily, when the temperature is greater than or equal to the preset temperature, the thermistor 3 is broken, shattered, shrunk or bent, so that the thermistor 3 can no longer block the high-pressure gas in the accommodating cavity 121, and the high-pressure gas passes through the thermistor 3 and flows out from the gas outlet 24.

[0043] The preset temperature is the preset temperature at which the thermistor 3 deforms, which is set based on actual test experience and is related to the temperature at which combustion occurs in the cabin. For example, the preset temperature may be 130°C, 140°C, 150°C, etc.

[0044] In specific implementation, the suspension system described in the present application is placed in the cabin, and the suspension system is used to connect the vehicle body longitudinal beam 9 and the power assembly 10. Under normal circumstances, when the temperature in the cabin is normal, the temperature of the guide tube 2 and the thermistor 3 located in the cabin is also normal. At this time, there is no gap between the outer wall of the thermistor 3 and the inner wall of the guide tube 2 so that the gas outlet end 24 is not connected to the accommodating cavity 121. In this way, the thermistor 3 successfully blocks the high-pressure gas in the accommodating cavity 121, preventing the high-pressure fire extinguishing gas in the accommodating cavity 121 from flowing out from the gas outlet end 24.

[0045] When an accidental fire occurs in the cabin, the cabin temperature rises, so that the temperature of the guide pipe 2 and the thermistor 3 located in the cabin also gradually increases. When the temperature is greater than or equal to the preset temperature, the volume of the thermistor 3 is deformed so that the gas outlet end 24 is connected with the accommodating chamber 121, so that the thermistor 3 can no longer block the high-pressure gas in the accommodating chamber 121, and the high-pressure gas passes through the thermistor 3 and flows out from the gas outlet end 24. The outflowing fire extinguishing gas can extinguish the fire burning in the cabin, play a fire extinguishing role, and improve the safety of the vehicle and its members.

[0046] In the present application, the suspension system can not only play the conventional role of connecting the vehicle powertrain 10 and the vehicle body, but also be used as a fire extinguishing device in the cabin. Under normal circumstances, the fire extinguishing gas in the accommodating chamber 121 can be blocked by the thermistor 3 and will not flow out from the gas outlet 24. When the cabin is burning so that the temperature of the thermistor 3 is greater than or equal to the preset temperature, the volume of the thermistor 3 is deformed to connect the gas outlet 24 with the accommodating chamber 121, and then the fire extinguishing gas in the accommodating chamber 121 flows out from the gas outlet 24. The outflowing fire extinguishing gas can extinguish the fire burning in the cabin, play a fire extinguishing role, and improve the safety of the vehicle and its members.

[0047] In some embodiments, the guide tube 2 includes a first guide portion 21 and a second guide portion 22 connected in sequence, the first guide portion 21 is arranged along a first direction, the second guide portion 22 is arranged along a second direction, the thermistor 3 is located in the first guide portion 21, the first direction is the length direction of the suspension frame 11, and the second direction is the width direction of the suspension frame 11.

[0048] Specifically, the first direction is the length direction of the suspension frame 11, that is, Figure 2 The second direction is the width direction of the suspension frame 11, that is, Figure 2 CD direction shown.

[0049] The first flow guide portion 21 is arranged along the first direction, that is, the first flow guide portion 21 extends along the length direction of the suspension frame 11. On the one hand, it is convenient to arrange the thermistor 3 in the first flow guide portion 21, so that the suspension frame 11 can quickly transfer heat to the thermistor 3, thereby improving the timeliness of fire extinguishing; on the other hand, it also allows the gas in the accommodating cavity 121 to flow quickly and smoothly from the accommodating cavity 121 to the first flow guide portion 21, thereby improving the efficiency of gas discharge.

[0050] The second air guide 22 is arranged along the second direction, that is, the first air guide 21 extends along the width direction of the suspension frame 11, and the gas outlet end 24 of the second air guide 22 is located on the side away from the vehicle body longitudinal beam 9. When the cabin burns, the flame generated by the combustion will burn upwards, so when the gas outlet end 24 of the second air guide 22 is located on the side away from the vehicle body longitudinal beam 9, the gas ejected from the gas outlet end 24 can just extinguish the flame burning upwards, thereby improving the efficiency of fire extinguishing.

[0051] In some embodiments, the thermistor 3 includes an outer shell and a liquid cavity located in the outer shell, the outer wall of the outer shell is connected to the inner wall of the guide tube 2, the liquid cavity is configured to accommodate a thermal expansion liquid, and the thermistor 3 is configured so that when the temperature is greater than or equal to a preset temperature, the thermal expansion liquid expands so that the outer shell breaks, so that the gas outlet end 24 is connected to the accommodating cavity 121.

[0052] Specifically, the shell can be made of glass material, and the wall thickness of the shell can be selected to be 0.01-3 mm, so that the shell is very easy to crack or break when the temperature is greater than or equal to a preset temperature.

[0053] The liquid cavity contains a heat expansion liquid, which can be kerosene or ether, for example. When the temperature is greater than or equal to the preset temperature, the heat expansion liquid expands so that the shell breaks, so that the gas outlet 24 is connected to the accommodating cavity 121, thereby playing a role in extinguishing the fire.

[0054] In the present application, the temperature at which the shell breaks can be adjusted by adjusting the thickness of the shell and the composition of the thermally expanded liquid in the liquid cavity, so as to ensure that when a fire occurs in the cabin, the shell can quickly break to release high-pressure fire extinguishing gas to ensure the safety of the vehicle and personnel.

[0055] It is worth noting that when the temperature is greater than or equal to the preset temperature, the thermal expansion liquid expands so that the shell breaks, thereby connecting the gas outlet 24 with the accommodating chamber 121, and the fire extinguishing gas in the accommodating chamber 121 can flow out from the gas outlet 24 to extinguish the fire. In this process, the thermal expansion liquid will not flow out from the gas outlet 24, so it will not affect the fire extinguishing effect of the fire extinguishing gas. This is because:

[0056] (1) The heat expansion liquid has its own gravity, so even if driven by the flowing fire extinguishing gas, the heat expansion liquid will not flow too long in the flow guide pipe 2;

[0057] (2) The thermistor 3 is located in the first guide portion 21, the first guide portion 21 is arranged along the first direction, the second guide portion 22 is arranged along the second direction, and the first direction and the second direction are perpendicular to each other. Therefore, even if the thermal expansion liquid can flow to the end of the first guide portion 21 close to the second guide portion 22, it will be blocked by the second guide portion 22 arranged perpendicular to the first guide portion 21, so that it cannot flow into the second guide portion 22, and will not flow out from the gas outlet 24.

[0058] In some embodiments, the suspension assembly 1 includes a suspension skeleton 11 and a rubber assembly 12, at least a portion of the rubber assembly 12 is located in the suspension skeleton 11, the rubber assembly 12 is provided with the accommodating cavity 121, and the air intake end 23 sequentially passes through the suspension skeleton 11 and the rubber assembly 12 and then extends into the accommodating cavity 121.

[0059] Specifically, the suspension frame 11 is used to be fixedly connected to the longitudinal beam 9 of the vehicle body, and is the structural frame of the suspension system. The suspension frame 11 is made of metal material, so that the suspension frame 11 has good thermal conductivity. When a fire occurs in the engine room of the vehicle, the temperature of the suspension frame 11 will rise rapidly, and the suspension frame 11 will quickly transfer the high-temperature heat to the guide tube 2 and the thermistor 3, so that the temperature of the thermistor 3 can rise rapidly, so that when the temperature rises to the preset temperature, the thermistor 3 will rupture and release the fire extinguishing gas, so that the fire can be extinguished quickly and timely to avoid safety hazards.

[0060] The rubber assembly 12 is made of a rubber material, and the rubber material has a certain elasticity, so that the rubber assembly 12 has a certain elasticity and deformability. The rubber assembly 12 is provided with the accommodating chamber 121 inside, and the accommodating chamber 121 is used to accommodate high-pressure fire extinguishing gas.

[0061] See also Figure 3 As shown, a pressure sensor 8 is provided in the accommodating chamber 121, and the pressure sensor 8 is used to monitor the pressure of the high-pressure fire extinguishing gas in the accommodating chamber 121. Each time the vehicle is started (the vehicle is in a stable state at this time, and the gas pressure is relatively stable. Due to the particularity of the suspension system, pressure monitoring is usually not performed during the driving process of the vehicle), the gas pressure in the accommodating chamber 121 is monitored by the pressure sensor 8. When the pressure exceeds the preset pressure range, a fault alarm is issued to indicate a functional failure of the suspension system.

[0062] The preset pressure range is the gas pressure range in the accommodating chamber 121 when the fire extinguishing function of the preset suspension system is normal. When the gas pressure in the accommodating chamber 121 is within the preset pressure range, it means that the gas pressure is normal at this time, and the suspension system can play a role in fire extinguishing normally; when the gas pressure in the accommodating chamber 121 is not within the preset pressure range, it means that the gas pressure is abnormal at this time, and the suspension system cannot play a role in fire extinguishing normally. At this time, a fault alarm needs to be issued to indicate a functional failure of the suspension system.

[0063] In the present application, the suspension skeleton 11 can quickly transfer the high temperature in the cabin to the thermistor 3 for rapid and effective fire extinguishing, and the pressure sensor 8 can monitor the gas pressure in the accommodating cavity 121 to monitor whether the fire extinguishing function of the suspension system is normal, thereby ensuring the effectiveness of the fire extinguishing function of the suspension system.

[0064] In some embodiments, a suspension bracket 6 is provided at one end of the rubber assembly 12 away from the suspension frame 11 , and the suspension bracket 6 is configured to be connected to the powertrain 10 of the vehicle for supporting the powertrain 10 of the vehicle.

[0065] Since the suspension bracket 6 supports the weight of the vehicle's powertrain 10, and the rubber assembly 12 has certain elasticity and deformability, when the gas in the accommodating chamber 121 flows out from the gas outlet end 24 of the guide tube 2, the volume of the accommodating chamber 121 will be compressed under the weight of the powertrain 10, so that the spraying of the fire extinguishing gas is smoother.

[0066] In some embodiments, the orthographic projection of the thermistor 3 in the first direction at least partially overlaps with the orthographic projection of the suspension frame 11 in the first direction, and the first direction is the length direction of the suspension frame 11 .

[0067] In some embodiments, the orthographic projection of the thermistor 3 in the first direction at least partially overlaps with the orthographic projection of the suspension frame 11 in the first direction, so that the metal suspension frame 11 can quickly transfer heat to the thermistor 3, so that the temperature of the thermistor 3 can be promptly and quickly increased. When the temperature rises to a preset temperature, the thermistor 3 ruptures and releases fire extinguishing gas, so that the fire can be extinguished quickly and timely to avoid safety hazards.

[0068] The first direction is the length direction of the suspension frame 11, that is, Figure 2 AB direction shown.

[0069] In some embodiments, an exhaust nozzle 4 is further included, and the exhaust nozzle 4 is disposed at an end of the second air guide portion 22 away from the first air guide portion 21 .

[0070] Specifically, an exhaust nozzle 4 is arranged at the end of the second guide portion 22 away from the first guide portion 21, which can improve the uniformity of the exhaust. When the high-pressure gas is ejected, it can spray the gas into the cabin more evenly, thereby improving the efficiency of fire extinguishing.

[0071] Optionally, an exhaust cavity is provided in the exhaust nozzle 4, and the inner diameter of the exhaust cavity gradually increases along the direction away from the first guide portion 21, so that the exhaust area can be increased and the fire extinguishing efficiency can be improved.

[0072] In some embodiments, the suspension system further includes an air intake pipe 5, one end of which extends into the accommodating cavity 121, and the other end of which is located outside the suspension assembly 1 for connecting to an external air intake passage. The air intake pipe 5 is used to replenish the accommodating cavity 121 with high-pressure fire extinguishing gas.

[0073] Optionally, a one-way valve 51 is provided on the air inlet pipe 5 to ensure that the high-pressure fire-extinguishing gas does not flow out of the accommodating chamber 121 through the air inlet pipe 5 .

[0074] In some embodiments, at least one filter screen 7 is further included. The filter screen 7 is located in the guide tube 2 and connected to the inner wall of the guide tube 2 . The filter screen 7 is located between the exhaust nozzle 4 and the thermistor 3 .

[0075] Specifically, the filter screen 7 only allows the gas to flow out, while filtering the residue of the broken thermistor 3 and the thermal expansion liquid, thereby improving the cleanliness of the cabin during the fire extinguishing process.

[0076] It is worth noting that it is also possible not to set the filter 7 in the suspension system, because the high-pressure gas is sprayed into the engine room, and the engine room and the vehicle cabin are separated. Therefore, even if the residue of the broken thermistor 3 and the thermal expansion liquid are sprayed into the engine room with the fire extinguishing gas, it will not affect the cabin and the personnel, and at most will only affect the cleanliness of the engine room. Therefore, if the filter 7 is set, the cleanliness of the engine room during the fire extinguishing process can be improved.

[0077] Based on the same inventive concept, see Figure 4 The present application also provides a vehicle, including the suspension system described in any of the above embodiments. The bottom of the suspension frame 11 of the suspension system is fixedly connected to the vehicle body longitudinal beam 9, and the top of the suspension bracket 6 of the suspension system is connected to the powertrain 10 of the vehicle. In this way, the suspension system can not only connect the vehicle body and the powertrain 10, but also play a role in fire extinguishing.

[0078] The vehicle has the technical effects of any of the above-mentioned embodiments, which will not be elaborated here.
