Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle housing device and a vehicle. Background Technology

[0002] In related technologies, fuel-powered vehicles include a fuel tank and an engine. The fuel tank is used to supply fuel to the engine, and the engine does work by burning the fuel, thereby converting the chemical energy of the fuel into mechanical energy.

[0003] Because fuel is volatile, it easily produces fuel vapor. If there is a large amount of fuel vapor in the fuel tank, the internal pressure can become too high. Therefore, related technologies for fuel-powered vehicles also include a containment device that can draw in and absorb fuel vapor to reduce the internal pressure of the fuel tank. The fuel vapor contained in the containment device can also be desorbed and discharged, allowing the fuel vapor to enter the engine as fuel.

[0004] Because the amount of fuel vapor changes dynamically, this has an adverse effect on the vehicle, and the degree of the adverse effect changes with the amount of fuel vapor. In related technologies, it is difficult for fuel-powered vehicles to reduce the degree of this adverse effect under the condition of dynamic changes in the amount of fuel vapor. Summary of the Invention

[0005] In view of this, this application provides a vehicle containment device and a vehicle that can more easily reduce the degree of adverse effects on the vehicle under conditions of dynamic changes in the amount of fuel vapor.

[0006] In a first aspect, this application provides a containing device, the containing device comprising a containing structure for containing an adsorbent for adsorbing fuel vapor; the containing structure is provided with an adsorption port, a desorption port, and an atmospheric port, the adsorption port being connected to a vehicle's fuel tank, the desorption port being connected to the intake manifold of the vehicle's engine, and the atmospheric port being connected to the external atmospheric environment of the containing device; the containing device has at least a state A and a state B; in state A, the volume of the space within the containing structure for drawing in the fuel vapor through the adsorption port is volume A; in state B, the volume of the space within the containing structure for drawing in the fuel vapor through the adsorption port is volume B; volume A is smaller than volume B.

[0007] When the amount of fuel vapor in the fuel tank is low, the containment device can be in state A to meet the need for drawing in a small amount of fuel vapor. When the amount of fuel vapor in the fuel tank is high, the containment device can be in state B to meet the need for drawing in a large amount of fuel vapor.

[0008] Furthermore, when used to inhale a small amount of fuel vapor, the containment device is in state A. The volume of the space within the containment structure for inhaling fuel vapor through the air inlet is relatively small, resulting in a relatively small amount of air in the space. Under these conditions, the rate at which the adsorbent ages due to contact with a small amount of air is relatively small, resulting in a relatively small rate of decrease in the adsorption capacity of the adsorbent, resulting in a relatively long service life of the adsorbent, and thus a relatively long maintenance cycle for the containment device.

[0009] Secondly, this application also provides a containing device, the containing device including a containing structure for containing an adsorbent for adsorbing fuel vapor; the containing structure is provided with an adsorption port, a desorption port and an atmospheric port, the adsorption port being connected to a vehicle's fuel tank, the desorption port being connected to the intake manifold of the vehicle's engine, and the atmospheric port being connected to the external atmospheric environment of the containing device; the containing device has at least a state C and a state D; in state C, the volume of the space within the containing structure for discharging the fuel vapor through the desorption port is volume C; in state D, the volume of the space within the containing structure for discharging the fuel vapor through the desorption port is volume D; the volume C is smaller than the volume D.

[0010] When the amount of fuel vapor in the containment structure is low, the containment device can be in state C so that the amount of air in the containment structure is not relatively high, and the ratio of fuel vapor to air in the containment structure is within a suitable range (the air-fuel ratio range that is conducive to obtaining greater engine power).

[0011] When the amount of fuel vapor in the containment structure is relatively large, the containment device can be in state D so that the amount of air in the containment structure is not relatively small, and the ratio of fuel vapor to air in the containment structure is within a suitable range (the air-fuel ratio range that is conducive to obtaining greater engine power).

[0012] When the engine needs to perform work with fuel vapor and air within the containment structure and the desorption port is open, the vehicle's negative pressure device can extract the mixture of fuel vapor and air with a suitable air-fuel ratio within the containment structure through the desorption port to supply the mixture to the engine's intake manifold, thereby enabling the engine to effectively output greater power.

[0013] Thirdly, this application provides a vehicle that includes the housing device described above. Therefore, the vehicle of this application may also include the technical effects of the housing device described above.

Detailed Implementation

[0018] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application. The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0020] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] In a first aspect, embodiments of this application provide a containment device for a vehicle, the containment device being used to draw in and adsorb fuel vapor from a fuel tank, and the containment device also being used to desorb and supply fuel vapor to an engine.

[0022] Please refer to Figure 1 As shown, a fuel-powered vehicle may include a fuel filler pipe, a fuel tank, a containment device, and an engine.

[0023] External fuel supply devices (such as refueling nozzles) inject fuel into the fuel tank through a fuel filling pipe. The fuel can include at least one flammable substance selected from gasoline, diesel, methanol, ethanol, liquefied natural gas, and liquid hydrogen. Due to the volatility of fuels, a significant amount of fuel vapor is generated inside the fuel tank during refueling, potentially leading to high internal pressure. This can cause structural deformation of the fuel tank, and the pressure sensor on the refueling nozzle may stop refueling if it detects excessive pressure, making the refueling process difficult. Similarly, higher ambient temperatures can also cause excessive fuel vapor to be generated inside the fuel tank, further increasing internal pressure and the risk of structural deformation. Therefore, fuel vapor can be contained within a confining device to reduce internal pressure, making refueling easier and minimizing the likelihood of fuel tank deformation.

[0024] Please refer to Figure 2 As shown, the containment structure 1 of the containment device 10 is provided with an adsorption port 1a, which can be connected to the fuel tank (not shown in the figure). Fuel vapor in the fuel tank can enter the containment structure 1 through the adsorption port 1a. The containment structure 1 also contains an adsorbent (not shown in the figure), which is used to adsorb fuel vapor. The adsorbent has good adsorption properties, which allows the containment device to hold more fuel vapor.

[0025] Adsorbents can include at least one of the following substances with a microporous structure: activated carbon, sponge, and polymers. In other words, any substance capable of absorbing molecules of other substances in the surrounding medium (such as various inorganic ions, organic polar molecules, and gas molecules) can be used as an adsorbent. The following content mainly uses activated carbon as an example to introduce adsorbents. Accordingly, the containing device 10 can be called a carbon canister.

[0026] It should be noted that the adsorption port 1a does not mean that the port structure has an adsorption function, but rather that fuel vapor can be adsorbed by the adsorbent in the containing structure 1 after passing through the adsorption port 1a from the fuel tank. Therefore, the adsorption port 1a can also be understood as a port structure in the containing structure 1 for drawing fuel vapor from the fuel tank.

[0027] Please refer to Figure 2 As shown, the containment structure 1 is provided with an atmospheric port 1c, which can communicate with the external atmospheric environment of the containment device 10. When fuel vapor enters the containment structure 1, the air inside the containment structure 1 can be discharged to the atmospheric environment through the atmospheric port 1c, so that the internal pressure of the containment structure 1 is also relatively balanced.

[0028] When the vehicle is started, the vehicle's negative pressure device can extract the fuel vapor from the containment structure 1. The extracted fuel vapor will enter the engine so that the fuel vapor can be burned and do work in the engine.

[0029] Please refer to Figure 2 As shown, the containment structure 1 is provided with a desorption port 1b, which can be connected to the intake manifold of the engine, and the fuel vapor in the containment structure 1 can enter the engine through the desorption port 1b.

[0030] It should be noted that the process of fuel vapor separating from adsorbates is called desorption, or desorption process. During desorption, air in the atmosphere can pass through... Figure 2 The atmospheric vent 1c shown enters the housing structure 1 to make the internal pressure of the housing structure 1 relatively balanced. Moreover, part of the air entering the housing structure 1 will mix with the desorbed fuel vapor and enter the engine together, thereby assisting the combustion of fuel vapor.

[0031] It should be noted that the desorption port 1b does not mean that the port structure has a desorption function, but rather that the fuel vapor, after desorbing from the adsorbate in the housing structure 1, will enter the engine through the desorption port 1b. Therefore, the desorption port 1b can also be understood as a port structure within the housing structure 1 used to supply fuel vapor to the engine.

[0032] It should be noted that when the engine is started, the desorption port 1b can be in the open state to allow the desorbed fuel vapor in the containment structure 1 to enter the engine. When the engine is stopped, the desorption port 1b can be in the closed state to prevent the fuel vapor in the containment structure 1 from entering the engine.

[0033] It should be noted that the adsorbent does not necessarily need to completely occupy all the space within the containment structure 1 (the space through which fuel vapor can pass). Therefore, the fuel vapor within the containment structure 1 may not be completely adsorbed by the adsorbent, and the fuel vapor may also be present in the space within the containment structure 1 that is not occupied by the adsorbent. Therefore, the amount of fuel vapor that can be inhaled by the containment device 10 can be greater than or equal to the adsorption saturation of the adsorbent (the upper limit of the adsorption capacity of the adsorbent).

[0034] Please refer to Figure 2 As shown, the containment device 10 can have at least state A and state B. In state A, the volume of the space (the space pointed to by the black triangular arrow) in the containment structure 1 for drawing in fuel vapor through the adsorption port 1a is volume A. In state B, the volume of the space (the space pointed to by the black triangular arrow) in the containment structure 1 for drawing in fuel vapor through the adsorption port 1a is volume B. Volume A is smaller than volume B.

[0035] When the amount of fuel vapor in the fuel tank is low, the containment device 10 can be in state A to meet the requirement of drawing in a small amount of fuel vapor. When the amount of fuel vapor in the fuel tank is high, the containment device 10 can be in state B to meet the requirement of drawing in a large amount of fuel vapor.

[0036] Although there are large-capacity (e.g., greater than 1L or greater than 1.5L) containment devices in related technologies to meet the needs of inhaling different amounts of fuel vapor, when the amount of fuel vapor inhaled by a large-capacity containment device is relatively small, the amount of air inside the large-capacity containment device is relatively large. Under this condition, the adsorbent is easily aged by a larger amount of air due to contact with more air, resulting in a relatively large rate of decline in the adsorption capacity of the adsorbent, a relatively short service life of the adsorbent, and thus a relatively short maintenance cycle for the large-capacity containment device.

[0037] The containment device provided in this application embodiment can be in state A when a small amount of fuel vapor is inhaled. The volume of the space inside the containment structure for inhaling fuel vapor through the air inlet is relatively small, resulting in a relatively small amount of air in the space. Under this condition, the rate at which the adsorbent ages due to contact with a small amount of air is relatively small, resulting in a relatively small rate of decrease in the adsorption capacity of the adsorbent, resulting in a relatively long service life of the adsorbent, and thus a relatively long maintenance cycle for the containment device.

[0038] It should be noted that although adsorbates are also aged by fuel vapor, the rate of aging by fuel vapor is lower than the rate of aging by air. This is because fuel vapor has a higher viscosity than air, and its flowability is relatively poor. Therefore, the fuel vapor adsorbed within the adsorbate can, to some extent, prevent substances in the air, such as oxygen, water vapor, or dust particles, that easily cause aging from entering the adsorbate. However, the air adsorbed within the adsorbate does not easily prevent substances that can cause aging from entering the adsorbate. Moreover, the prerequisite for adsorbates to be aged by fuel vapor is that the adsorbate has fulfilled its function of adsorbing fuel vapor; that is, the adsorbate is aged under the condition of effectively adsorbing fuel vapor. Aging of adsorbates due to the adsorption of other substances such as oxygen, water vapor, or dust particles from the air is a more ineffective form of aging.

[0039] It should be noted that the change of the containment device 10 between state A and state B is controlled by the vehicle. For example, if the vehicle detects that the air pressure in the fuel tank is low through the vehicle's air pressure detection device, the vehicle can determine that the amount of fuel vapor in the fuel tank is low, and the vehicle can control the containment device 10 to be in state A. If the vehicle detects that the air pressure in the fuel tank is high through the vehicle's air pressure detection device, the vehicle can determine that the amount of fuel vapor in the fuel tank is high, and the vehicle can control the containment device 10 to be in state B.

[0040] It should be noted that volume A can be a specific value or a range value, and volume B can be a specific value or a range value. Regardless of whether volume A or volume B is a specific value or a range value, volume A and volume B have no mathematical intersection, and volume A is smaller than volume B.

[0041] Please refer to Figure 2 As shown, the containment device 10 may also have at least state C and state D. In state C, the volume of the space within the containment structure 1 used to discharge fuel vapor through the desorption port 1b (the space pointed to by the black triangular arrow) is volume C. In state D, the volume of the space within the containment structure 1 used to discharge fuel vapor through the desorption port 1b (the space pointed to by the black triangular arrow) is volume D. Volume C is smaller than volume D.

[0042] When the amount of fuel vapor in the containment structure 1 is low, the containment device 10 can be in state C so that the amount of air in the containment structure 1 is not relatively high, so that the ratio of fuel vapor to air in the containment structure 1 is within a suitable range (an air-fuel ratio range that is conducive to obtaining greater engine power).

[0043] When the amount of fuel vapor in the containment structure 1 is relatively large, the containment device 10 can be in state D so that the amount of air in the containment structure 1 is not relatively small, so that the ratio of fuel vapor to air in the containment structure 1 is within a suitable range (an air-fuel ratio range that is conducive to obtaining greater engine power).

[0044] When the engine needs to perform work by accommodating fuel vapor and air in the containment structure 1 and the desorption port 1b is in the open state, the negative pressure device can extract the mixture of fuel vapor and air with a suitable air-fuel ratio range (hereinafter referred to as air-fuel ratio) in the containment structure 1 through the desorption port 1b to supply the mixture to the intake manifold of the engine, thereby enabling the engine to effectively output greater power.

[0045] Related technologies include large-capacity (e.g., greater than 1L or 1.5L) containment devices. When the amount of fuel vapor drawn into a large-capacity containment device is relatively small, the amount of air inside is relatively large. Under these conditions, the ratio of fuel vapor to air within the large-capacity containment device is not easily within a suitable range (the air-fuel ratio that is conducive to obtaining greater engine power). When the engine needs fuel vapor and air to perform work and the desorption port is open, the fuel vapor and air without a suitable air-fuel ratio are not conducive to the engine effectively outputting greater power. Even in the initial stage of the negative pressure device extracting gas from the large-capacity containment device, air is more easily extracted than fuel vapor, resulting in an even more unsuitable fuel vapor to air ratio, which is even more detrimental to the engine effectively outputting greater power.

[0046] Related technologies also include schemes that use large-capacity containment devices and small-capacity (e.g., less than 1L) containment devices in parallel. When the amount of fuel vapor is relatively small, the small-capacity containment device is used, and when the amount of fuel vapor is relatively large, the large-capacity containment device is used. However, this technology results in a relatively large volume of the containment device structure, which occupies more installation space in the vehicle, and it is also more difficult to control and maintain.

[0047] It should be noted that the change between state C and state D of the containment device 10 is controlled by the vehicle. For example, the vehicle can detect the amount of fuel vapor in the containment device 10 through the vehicle's air pressure detection device and / or gas flow detection device. If the vehicle detects that the amount of fuel vapor in the containment device 10 is relatively small, the vehicle can control the containment device 10 to be in state C; if the vehicle detects that the amount of fuel vapor in the containment device 10 is relatively large, the vehicle can control the containment device 10 to be in state D.

[0048] It should be noted that volume C can be a specific value or a range value, and volume D can be a specific value or a range value. Regardless of whether volume C or volume D is a specific value or a range value, volume C and volume D have no mathematical intersection, and volume C is smaller than volume D.

[0049] It should be noted that states A and B described in this article may or may not be related to states C and D.

[0050] In one possible scenario, the containing device 10 can be in state A or simultaneously in state C, and correspondingly, the volume A can be equal to the volume C.

[0051] In one possible scenario, the receiving device 10 may be in state A or not in state C.

[0052] In one possible scenario, the receiving device 10 may be in state C or not in state A.

[0053] In one possible scenario, the containing device 10 can be in state B or simultaneously in state D, and correspondingly, the volume B can be equal to the volume D.

[0054] In one possible scenario, the receiving device 10 may be in state B or not in state D.

[0055] In one possible scenario, the receiving device 10 may be in state D or not in state B.

[0056] Furthermore, regarding states A and B, it should be noted that, as Figure 2 As shown, the space within the containment structure 1 used for drawing in fuel vapor through the adsorption port 1a (the space pointed to by the black triangular arrow) mainly refers to the space that fuel vapor can enter after passing through the adsorption port 1a in state A or state B. The space pointed to by the black triangular arrow may be a part of the containment structure 1 that is connected to the adsorption port 1a. When the number of spaces that can connect to the adsorption port 1a increases, i.e., more parts of the space are connected, the volume of the space within the containment structure 1 used for drawing in fuel vapor through the adsorption port 1a is relatively large. When the number of spaces that can connect to the adsorption port 1a decreases, i.e., fewer parts of the space are connected, the volume of the space within the containment structure 1 used for drawing in fuel vapor through the adsorption port 1a is relatively small. The space pointed to by the black triangular arrow may also be a space within the containment structure 1 whose volume increases or decreases due to changes in the position of a certain part of the structure.

[0057] Similarly, regarding states C and D, it should be noted that, as Figure 2 As shown, the space within the containment structure 1 used to discharge fuel vapor through the desorption port 1b (the space pointed to by the black triangular arrow) mainly refers to the space that can supply fuel vapor to the desorption port 1b in state C or state D. The space pointed to by the black triangular arrow may be a part of the containment structure 1 that is connected to the desorption port 1b. When the number of spaces that can connect to the desorption port 1b increases, i.e., more parts of the space are connected, the volume of the space within the containment structure 1 used to supply fuel vapor to the desorption port 1b is relatively large. When the number of spaces that can connect to the desorption port 1b decreases, i.e., fewer parts of the space are connected, the volume of the space within the containment structure 1 used to supply fuel vapor to the desorption port 1b is relatively small. The space pointed to by the black triangular arrow may also be a space within the containment structure 1 whose volume increases or decreases due to changes in the position of a certain part of the structure.

[0058] The following sections will first discuss how changes in the number of connected spaces affect the volume of the space, and then discuss changes in the volume of a single space.

[0059] Regarding the change in the number of connected spatial segments that affects the spatial volume: Optionally, regarding states A and B, the containment structure 1 is provided with at least two containment chambers. In state A, one of the containment chambers draws in fuel vapor through an adsorption port, so the containment structure 1 can draw in relatively less fuel vapor. In state B, at least two containment chambers draw in fuel vapor through adsorption ports, so the containment structure 1 can draw in relatively more fuel vapor.

[0060] The accommodating structure 1 may have two, three, four or more accommodating cavities.

[0061] It should be noted that, in state A, one of the accommodating chambers that draws in fuel vapor through the adsorption port contains adsorbent, and in state B, at least one of the at least two accommodating chambers that draw in fuel vapor through the adsorption port contains adsorbent.

[0062] In other embodiments, in state A, two containment chambers may draw in fuel vapor through adsorption ports, and in state B, three or more containment chambers may draw in fuel vapor through adsorption ports.

[0063] Therefore, the number of cavities connected to the adsorption port in state A should be less than the number of cavities connected to the adsorption port in state B.

[0064] Similarly, regarding states C and D, the containment structure 1 may be provided with at least two containment chambers. In state C, the desorption port is used to discharge fuel vapor from one of the containment chambers so that a mixture with a suitable air-fuel ratio can enter the engine. In state D, the desorption port is used to discharge fuel vapor from at least two containment chambers so that a mixture with a suitable air-fuel ratio can enter the engine.

[0065] The accommodating structure 1 may have two, three, four or more accommodating cavities.

[0066] It should be noted that, in state C, one of the cavities supplying fuel vapor to the desorption port contains adsorbate, and in state D, at least one of the at least two cavities supplying fuel vapor to the desorption port contains adsorbate.

[0067] In other embodiments, in state C, the number of cavities supplying fuel vapor to the desorption port may be two, and in state D, the number of cavities supplying fuel vapor to the desorption port may be three or more.

[0068] Therefore, the number of cavities connected to the desorption port in state C should be less than the number of cavities connected to the desorption port in state D.

[0069] Alternatively, for embodiments regarding state A and state B, please refer to... Figure 3 As shown, the containment structure 1 has two containment chambers, one of which is the first containment chamber 1d, and the other is the second containment chamber 1e. The adsorbate is located at least in the first containment chamber 1d. In state A, the first containment chamber 1d is connected to the adsorption port 1a, and fuel vapor can enter the first containment chamber 1d through the adsorption port 1a. However, the first containment chamber 1d is not connected to the second containment chamber 1e, and fuel vapor will not enter the second containment chamber 1e. Therefore, the volume of the space within the containment structure 1 used for drawing in fuel vapor through the adsorption port 1a is relatively small. In state B, the second containment chamber 1e is connected to the adsorption port 1a through the first containment chamber 1d. Fuel vapor can enter both the first containment chamber 1d and the second containment chamber 1e through the adsorption port 1a. Therefore, the volume of the space within the containment structure 1 used for drawing in fuel vapor through the adsorption port 1a is relatively large.

[0070] The first receiving cavity 1d may contain an adsorbent, while the second receiving cavity 1e may not contain an adsorbent. Alternatively, both the first receiving cavity 1d and the second receiving cavity 1e may contain an adsorbent.

[0071] Similarly, for the implementation examples of states C and D, please refer to... Figure 3 As shown, the containment structure 1 can be provided with two containment chambers, one of which is the first containment chamber 1d and the other is the second containment chamber 1e. The adsorbate is located at least in the first containment chamber 1d. In state C, the first containment chamber 1d is connected to the desorption port 1b, and the fuel vapor in the first containment chamber 1d can enter the engine through the desorption port 1b. In state D, the second containment chamber 1e is connected to the desorption port 1b through the first containment chamber 1d, and the fuel vapor in the first containment chamber 1d and the fuel vapor in the second containment chamber 1e can enter the engine through the desorption port 1b.

[0072] The first receiving cavity 1d may contain an adsorbent, while the second receiving cavity 1e may not contain an adsorbent. Alternatively, both the first receiving cavity 1d and the second receiving cavity 1e may contain an adsorbent.

[0073] Alternatively, for embodiments regarding state A and state B, please refer to... Figure 3As shown, the receiving structure 1 includes a receiving body 11 and a partition 12 connected to each other. The receiving body 11 is provided with a first receiving cavity 1d and a second receiving cavity 1e. The first receiving cavity 1d and the second receiving cavity 1e are separated by the partition 12. The receiving device 10 also includes an on / off valve 2. When the on / off valve 2 is in the closed state, the first receiving cavity 1d and the second receiving cavity 1e are blocked, so that the receiving device 10 can be in state A. When the on / off valve 2 is in the open state, the first receiving cavity 1d and the second receiving cavity 1e are connected, so that the receiving device 10 can be in state B.

[0074] Similarly, for the implementation examples of states C and D, please refer to... Figure 3 As shown, the receiving structure 1 includes a receiving body 11 and a partition 12 connected to each other. The receiving body 11 is provided with a first receiving cavity 1d and a second receiving cavity 1e. The first receiving cavity 1d and the second receiving cavity 1e are separated by the partition 12. The receiving device 10 also includes an on / off valve 2. When the on / off valve 2 is in the closed state, the first receiving cavity 1d and the second receiving cavity 1e are blocked, so that the receiving device 10 can be in state C. When the on / off valve 2 is in the open state, the first receiving cavity 1d and the second receiving cavity 1e are connected, so that the receiving device 10 can be in state D.

[0075] The number of on / off valves 2 provided in the partition 12 can be one, two, three or more. When there are at least two on / off valves 2 in the partition 12, and at least two on / off valves 2 are in the open state, the gas flow rate between the first receiving chamber 1d and the second receiving chamber 1e is faster. For example, it is beneficial for fuel vapor to quickly enter the second receiving chamber 1e from the first receiving chamber 1d, or for fuel vapor to quickly enter the first receiving chamber 1d from the second receiving chamber 1e.

[0076] Alternatively, please refer to Figures 4-5 As shown, the on / off valve 2 includes an elastic element 21 and a sealing element 22. The sealing element 22 is connected to the receiving body 11 via the elastic element 21. The partition 12 is provided with a first connecting hole 12a. Please refer to... Figure 4 As shown, when the on / off valve 2 is in the closed state, under the elastic force of the elastic member 21, the sealing member 22 seals the first connecting hole 12a, blocking the first receiving cavity 1d and the second receiving cavity 1e, so that the receiving device 10 is in state A and / or state C as mentioned herein. Please refer to Figure 5 As shown, when the on / off valve 2 is in the open state, under the action of external force, the sealing member 22 separates from the first connecting hole 12a, and the first receiving cavity 1d is connected to the second receiving cavity 1e through the first connecting hole 12a, so that the receiving device 10 is in state B and / or state D as mentioned herein.

[0077] It should be noted that when the on / off valve 2 is in the open state, the external force acting on the sealing member 22 refers to the elastic force of the non-elastic member 21. For example, the sealing member 22 may include a ferromagnetic material, and the sealing member 22 can be controlled (magnetically attracted or magnetically repelled) by the magnetic field of an electromagnetic coil (not shown in the figure) located outside the receiving structure 1, so that the sealing member 22 can overcome the elastic force of the elastic member 21, thereby separating the sealing member 22 from the first connecting hole 12a. Alternatively, the sealing member 22 is physically connected to a driving structure (not shown in the figure), the driving structure may pass through the receiving structure 1, and the driving structure may be movable, so that the sealing member 22 overcomes the elastic force of the elastic member 21, thereby separating the sealing member 22 from the first connecting hole 12a.

[0078] In other embodiments (not shown in the figures), the sealing element may also be connected to the partition via an elastic element.

[0079] Alternatively, please refer to Figures 6-7 As shown, the on / off valve 2 includes an elastic element 21, a sealing element 22, and a valve body 23. The sealing element 22 is connected to the valve body 23 through the elastic element 21. The valve body 23 passes through the partition 12 and is provided with a second connecting hole 23a. Please refer to... Figure 6 As shown, when the on / off valve 2 is in the closed state, under the elastic force of the elastic member 21, the sealing member 22 seals the second connecting hole 23a, blocking the first receiving cavity 1d and the second receiving cavity 1e, so that the receiving device 10 is in state A and / or state C as mentioned herein. Please refer to Figure 7 As shown, when the on / off valve 2 is in the open state, under the action of external force, the sealing member 22 separates from the second connecting hole 23a, and the first receiving cavity 1d is connected to the second receiving cavity 1e through the second connecting hole 23a, so that the receiving device 10 is in state B and / or state D as mentioned herein.

[0080] It should be noted that when the on / off valve 2 is in the open state, the external force acting on the sealing element 22 refers to the elastic force of the non-elastic element 21. For example, the sealing element 22 may be made of ferromagnetic material, and the sealing element 22 can be controlled by the magnetic force (magnetic attraction or magnetic repulsion) of an electromagnetic coil (not shown in the figure) located outside the receiving structure 1, so that the sealing element 22 can overcome the elastic force of the elastic element 21, thereby separating the sealing element 22 from the second connecting hole 23a. Alternatively, the sealing element 22 is physically connected to the driving structure (not shown in the figure), the driving structure may pass through the receiving structure 1, and the driving structure may be movable, so that the sealing element 22 overcomes the elastic force of the elastic element 21, thereby separating the sealing element 22 from the second connecting hole 23a.

[0081] In embodiments involving states A and B, please refer to Figure 3 As shown, the receiving structure 1 may be provided with a desorption port 1b. For other embodiments involving states A and B, please refer to... Figure 8 As shown, the receiving structure 1 can also be provided with two desorption ports 1b, the first receiving cavity 1d is connected to one of the desorption ports 1b, and the second receiving cavity 1e is connected to the other desorption port 1b.

[0082] In the embodiment involving states C and D, please refer to Figure 3 As shown, the housing structure 1 may be provided with an atmospheric vent 1c. For other embodiments involving states C and D, please refer to... Figure 9 As shown, the housing structure 1 can also be provided with two atmospheric ports 1c, the first housing cavity 1d is connected to one of the atmospheric ports 1c, and the second housing cavity 1e is connected to the other atmospheric port 1c.

[0083] Content regarding changes in the volume of a single space: The containment structure may contain a single containment cavity, to which the adsorption port, desorption port, and atmospheric port are each connected. The adsorbate is located within this single containment cavity, and the volume of this single containment cavity is variable. Changes in the position of the enclosing structures within the containment structure that form the single containment cavity cause changes in the volume of the single containment cavity.

[0084] In this context, the volume A of a single containment cavity in state A can be smaller than the volume B of a single containment cavity in state B. The requirements and technical effects of the containment device switching between state A and state B have been described above, namely, that it can extend the service life of the adsorbent, thereby extending the maintenance cycle of the containment device; these will not be elaborated upon here.

[0085] Furthermore, the volume C of a single receiving cavity in state C can be smaller than the volume D of a single receiving cavity in state D. The requirements and technical effects that the receiving device can switch between state C and state D can meet have been described above. That is, the receiving device in both state C and state D can provide the engine with a mixture of fuel vapor and air with a suitable air-fuel ratio through the desorption port, so that the engine can output greater power. This will not be elaborated further here.

[0086] Please refer to Figures 10-11 As shown, the receiving structure 1 includes a receiving main body 11 and a movable component 13 that are movably connected. The receiving main body 11 has an active space, and the movable component 13 is located in the active space. The active space is divided by the movable component 13 to form a single receiving cavity 1f and a secondary cavity 1g.

[0087] Under the action of an external force, the movable member 13 can move relative to the receiving body 11 at least between a first position and a second position, wherein the volume of a single receiving cavity 1f when the movable member 13 is in the first position is different from the volume of a single receiving cavity 1f when the movable member 13 is in the second position. For example, the volume of a single receiving cavity 1f when the movable member 13 is in the first position is smaller than the volume of a single receiving cavity 1f when the movable member 13 is in the second position. Alternatively, the volume of a single receiving cavity 1f when the movable member 13 is in the first position is larger than the volume of a single receiving cavity 1f when the movable member 13 is in the second position.

[0088] Please refer to Figure 10 As shown, the movable member 13 can be slidably connected to the receiving body 11. For example, the movable member 13 can slide relative to the receiving body 11 in the X direction to increase the volume of the single receiving cavity 1f, and the movable member 13 can slide relative to the receiving body 11 in the Y direction to decrease the volume of the single receiving cavity 1f.

[0089] Please refer to Figure 11 As shown, the movable member 13 can be rotatably connected to the receiving body 11. For example, the movable member 13 can rotate relative to the receiving body 11 in direction j to increase the volume of the single receiving cavity 1f, and the movable member 13 can rotate relative to the receiving body 11 in direction k to decrease the volume of the single receiving cavity 1f.

[0090] It should be noted that when the volume of a single receiving cavity 1f increases, the volume of the secondary cavity 1g decreases, and when the volume of a single receiving cavity 1f decreases, the volume of the secondary cavity 1g increases. The secondary cavity 1g can be connected to the outside of the receiving structure 1 through the port 1h so that the air pressure inside the secondary cavity 1g and outside the receiving structure 1 is relatively balanced.

[0091] It should be noted that the movable element 13 may be made of ferromagnetic material. The movable element 13 can be controlled by the magnetic field (magnetic attraction or magnetic repulsion) of an electromagnetic coil (not shown in the figure) located outside the receiving structure 1, so that the movable element 13 can move relative to the receiving body 11, thereby changing the volume of the individual receiving cavity 1f. Alternatively, the movable element 13 can be physically connected to a driving structure (not shown in the figure). The driving structure can pass through the receiving body 11 and can move, so that the movable element 13 can move relative to the receiving body 11, thereby changing the volume of the individual receiving cavity 1f.

[0092] It should be noted that the active space provided by the accommodating body 11 includes at least a single accommodating cavity 1f and a secondary cavity 1g.

[0093] In other embodiments (not shown in the figures), the structure within the receiving structure used to enclose and form a single receiving cavity may include a flexible structure so that the size of the single receiving cavity can be varied.

The adsorption port of the containment device is connected to the fuel tank, and the desorption port of the containment device is connected to the intake manifold of the engine. Since the vehicle of this application embodiment includes the containment device described above, the vehicle of this application embodiment also includes the technical effects of the containment device described above, which will not be repeated here.

[0095] In this application embodiment, the vehicle can be a car, motorcycle, truck, tractor, all-terrain vehicle or engineering vehicle, or other vehicle with mobility function and powered by fuel.

[0096] In addition, an engine can be a device that outputs torque to the outside by doing work through combustion to drive the vehicle. Of course, an engine can also be a device that outputs torque to the outside by doing work through combustion to drive a generator to generate electricity.
