[0031] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0032] Reference is made below to Figures 1-4 Describe the carbon canister device 100 and the vehicle according to the embodiments of the present utility model. The carbon canister device 100 can be used to adsorb the fuel vapor volatilized from the vehicle fuel tank to prevent the fuel vapor from being directly discharged into the atmosphere and causing pollution.

[0033] The carbon canister device 100 according to the embodiments of the present utility model includes: an outer shell 10, the outer shell 10 defines an installation space 11, the outer shell 10 includes a first end housing 12, a second end housing 13 and a middle housing 14, the first end housing 12, the second end housing 13 and the middle housing 14 are used to define the installation space 11, the first end housing 12 and the second end housing 13 are oppositely arranged and fixedly connected, the middle housing 14 is selectively connected between the first end housing 12 and the second end housing 13 to change the volume of the installation space 11, the first end housing 12 is formed with a first interface 121, the second end housing 13 is formed with a second interface 131, and the installation space 11 communicates with the first interface 121 and the second interface 131; a purification unit 20, the purification unit 20 is disposed in the installation space 11 and is located between the first interface 121 and the second interface 131.

[0034] Among them, the outer shell 10, as the columnar structure of the carbon canister device 100, defines an installation space 11 for accommodating and fixing the purification unit 20. The outer shell 10 can be composed of a first end shell 12, a second end shell 13 and a middle shell 14. The first end shell 12, the second end shell 13 and the middle shell 14 are used to define the installation space 11, which not only defines the size and shape of the installation space 11, but also ensures the structural strength and sealing performance of the carbon canister device 100.

[0035] The first end shell 12 and the second end shell 13 are oppositely arranged and fixedly connected. The first end shell 12 and the second end shell 13 can be directly connected, or the first end shell 12 and the second end shell 13 can be indirectly fixedly connected through the middle shell 14. When the first end shell 12 and the second end shell 13 are directly connected, for example: the first end shell 12 and the second end shell 13 can be connected by welding, or the first end shell 12 and the second end shell 13 can be fixedly connected by snap connection, or the first end shell 12 and the second end shell 13 can be fixedly connected by bolts. However, the present invention is not limited thereto, and the first end shell 12 and the second end shell 13 can also be fixedly connected by other means, as long as the first end shell 12 and the second end shell 13 are oppositely arranged and fixedly connected. In this application, the connection between the first end shell 12 and the second end shell 13 by welding is taken as an example for illustration. For example: the first end shell 12 and the second end shell 13 can be connected by friction welding or rotary welding. Welding connection has the characteristics of high efficiency and speed, can significantly improve production efficiency and output, and through welding connection, the first end shell 12 and the second end shell 13 can be closely combined, enhancing the connection stability between the first end shell 12 and the second end shell 13, reducing the risk of loosening and falling off at the connection, and ensuring the integrity and functionality of the outer shell 10 during long-term use.

[0036] When the first end housing 12 and the second end housing 13 are directly connected, they can jointly define an installation space 11. When the middle housing 14 is connected between the first end housing 12 and the second end housing 13, the middle housing 14 is connected to the installation space 11 jointly defined by the first end housing 12 and the second end housing 13. The middle housing 14 is selectively connected between the first end housing 12 and the second end housing 13 to change the volume of the installation space 11. For example, the middle housing 14 can be fixedly connected to the first end housing 12 and the second end housing 13 by welding, or the middle housing 14 can be fixedly connected to the first end housing 12 and the second end housing 13 by bolts, or the middle housing 14 can be fixedly connected to the first end housing 12 and the second end housing 13 by snap connection. As long as the middle housing 14 is selectively connected between the first end housing 12 and the second end housing 13 to change the volume of the installation space 11. In this application, the case where the middle housing 14 is fixedly connected to the first end housing 12 and the second end housing 13 by welding is taken as an example for illustration. For example, the middle housing 14 can be fixedly connected to the first end housing 12 and the second end housing 13 by friction welding or rotary welding.

[0037] It is possible to reasonably select whether to connect the middle housing 14 between the first end housing 12 and the second end housing 13 according to the volume of the vehicle fuel tank. By selectively connecting the middle housing 14 between the first end housing 12 and the second end housing 13 to change the volume of the installation space 11, the volume of the carbon canister device 100 can be changed, so that the carbon canister device 100 can accommodate fuel tanks of different volumes, and the development cost of the carbon canister device 100 can also be reduced.

[0038] A first interface 121 is formed on the end wall of the first end housing 12 away from the second end housing 13. The first interface 121 can be used to communicate with the fuel tank of the vehicle. A second interface 131 is formed on the end wall of the second end housing 13 away from the first end housing 12. The second interface 131 can communicate with the external environment. The installation space 11 communicates with the first interface 121 and the second interface 131. The purification unit 20 is arranged in the installation space 11 and is located between the first interface 121 and the second interface 131. The fuel vapor volatilized from the fuel tank flows into the installation space 11 from the first interface 121. The purification unit 20 can adsorb oil molecules or impurities in the fuel vapor volatilized from the fuel tank. The purified vapor is discharged to the external environment through the second interface 131 to prevent the fuel vapor from being directly discharged into the atmosphere and causing pollution.

[0039] It can be explained that the purification unit 20 is activated carbon powder. The activated carbon powder has good adsorption performance and can effectively adsorb the excess fuel vapor generated in the fuel tank on its own surface, preventing the fuel vapor from being directly discharged into the atmosphere and causing pollution.

[0040] According to the canister device 100 of the embodiments of the present utility model, the first end housing 12, the second end housing 13 and the middle housing 14 are used to define an installation space 11. The first end housing 12 and the second end housing 13 are arranged opposite to each other and fixedly connected. The middle housing 14 is selectively connected between the first end housing 12 and the second end housing 13 to change the volume of the installation space 11, so as to change the volume of the canister device 100, enabling the canister device 100 to accommodate fuel tanks of different volumes and reducing the development cost of the canister device 100.

[0041] In some embodiments of the present utility model, such as Figure 2 and Figure 4 shown, the middle housing 14 includes at least one sub-middle housing 141. For example, the middle housing 14 can include one, two, three or other numbers of sub-middle housings 141, but the present utility model is not limited thereto. The middle housing 14 can also include other numbers of sub-middle housings 141, as long as the middle housing 14 includes at least one sub-middle housing 141. Further, the middle housing 14 with different numbers of sub-middle housings 141 can be reasonably selected according to the volume of the vehicle fuel tank to change the volume of the canister device 100. A purification unit 20 is filled in the canister device 100 to adsorb oil molecules in the fuel vapor volatilized from the fuel tank, so as to prevent the fuel vapor from being directly discharged into the atmosphere and causing pollution.

[0042] In some embodiments of the present utility model, such as Figure 4 shown, the middle housing 14 can include a plurality of sub-middle housings 141, and the plurality of sub-middle housings 141 are arranged in sequence along the arrangement direction of the first end housing 12 and the second end housing 13.

[0043] Among them, the middle housing 14 can include a plurality of sub-middle housings 141. For example, the middle housing 14 can include two, three, four or other numbers of sub-middle housings 141, but the present utility model is not limited thereto. The middle housing 14 can also include other numbers of sub-middle housings 141, as long as the middle housing 14 includes a plurality of sub-middle housings 141. The plurality of sub-middle housings 141 are arranged in sequence along the arrangement direction of the first end housing 12 and the second end housing 13. By connecting different numbers of sub-middle housings 141 between the first end housing 12 and the second end housing 13, the total volume of the canister device 100 can be flexibly adjusted to adapt to vehicle fuel tanks of different volumes, and the plurality of sub-middle housings 141 can be fixedly connected by welding, which can significantly improve the overall structural strength of the canister device 100.

[0044] In some embodiments of the present utility model, the structures of multiple sub-middle housings 141 can be the same. Specifically, each sub-middle housing 141 is an independent module with the same interface and size standard, and can be easily combined with other sub-middle housings 141 or the first end housing 12 and the second end housing 13. By increasing or decreasing the number of sub-middle housings 141, the total volume of the carbon canister device 100 can be flexibly adjusted to adapt to vehicle fuel tanks of different volumes. Moreover, the volumes of each sub-middle housing 141 can be the same. For example, the volume of each sub-middle housing 141 can be 0.3L.

[0045] Furthermore, the volume of one sub-middle housing 141 can be 0.3L, and the volume of the carbon canister device 100 without connecting the middle housing 14 between the first end housing 12 and the second end housing 13 is 1.7L. According to the corresponding relationship between the vehicle fuel tank volume and the volume of the carbon canister device 100, it is determined whether to connect the middle housing 14 between the first end housing 12 and the second end housing 13.

[0046] When the vehicle fuel tank volume is 50L, the corresponding volume of the carbon canister device 100 needs to be 1.7L. As the first embodiment of this application, as Figure 2 shown, there is no connection of the middle housing 14 between the first end housing 12 and the second end housing 13. At this time, the carbon canister device 100 can meet the usage requirements of a fuel tank with a volume of 50L.

[0047] When the vehicle fuel tank volume is 60L, the corresponding volume of the carbon canister device 100 needs to be 2L. As the second embodiment of this application, as Figure 3 shown, the middle housing 14 is connected between the first end housing 12 and the second end housing 13, and the middle housing 14 includes one sub-middle housing 141. At this time, the carbon canister device 100 can meet the usage requirements of a fuel tank with a volume of 60L.

[0048] When the vehicle fuel tank volume is 70L, the corresponding volume of the carbon canister device 100 needs to be 2.3L. As the third embodiment of this application, as Figure 4 shown, the middle housing 14 is connected between the first end housing 12 and the second end housing 13, and the middle housing 14 includes two sub-middle housings 141. At this time, the carbon canister device 100 can meet the usage requirements of a fuel tank with a volume of 70L.

[0049] Therefore, according to the corresponding relationship between the volume of the vehicle fuel tank and the volume of the carbon canister device 100, it is possible to select whether to connect the middle housing 14 between the first end housing 12 and the second end housing 13, and reasonably set the sub-middle housing 141 to flexibly adjust the volume of the carbon canister device 100 to meet the requirements of vehicle fuel tanks with different volumes, without the need to design and develop different carbon canister devices 100, improving the versatility of the carbon canister device 100, and thus being able to reduce the development cost of the carbon canister device 100.

[0050] In some embodiments of the present invention, for example Figure 1 As shown, the carbon canister device 100 may further include: a first filter element 15, the first filter element 15 is disposed in the installation space 11 and located between the purification unit 20 and the first interface 121, and the first filter element 15 covers the first interface 121.

[0051] Among them, the first filter element 15 may be made of non-woven fabric material. The non-woven fabric material has good filtering performance, air permeability, water permeability, corrosion resistance and wear resistance. Disposing the first filter element 15 in the installation space 11 and between the purification unit 20 and the first interface 121, and the first filter element 15 covering the first interface 121 can prevent the activated carbon powder in the purification unit 20 from entering the fuel tank, thereby avoiding adverse effects on the cleanliness of the fuel and the normal operation of the system. And the air permeability and water permeability of the non-woven fabric ensure that while blocking the activated carbon powder from entering the fuel tank, it will not overly impede the flow of fuel vapor, so that the first filter element 15 can protect the fuel system without becoming a bottleneck for the normal operation of the system. In addition, the corrosion resistance and wear resistance of the non-woven fabric also enable it to maintain stable performance in various harsh working environments, extending the service life of the first filter element 15 and reducing the maintenance cost.

[0052] In some embodiments of the present invention, for example Figure 1 As shown, the first end housing 12 further forms a third interface 122, the third interface 122 is communicated with the installation space 11, and the purification unit 20 is located between the third interface 122 and the second interface 131.

[0053] Among them, a third interface 122 may be formed on the end wall of the first end housing 12 away from the second end housing 13. The third interface 122 and the first interface 121 are located on the same end wall. The second interface 131 is located on the end wall of the second end housing 13 away from the first end housing 12. The first interface 121, the third interface 122 and the second interface 131 are arranged opposite to each other and communicate. The third interface 122 can be connected to the engine of the vehicle. The third interface 122 communicates with the installation space 11. The purification unit 20 is located between the third interface 122 and the second interface 131. In order to maintain the pressure balance in the carbon canister device 100 or promote the flow of fuel vapor, the gas in the external environment can enter the installation space 11 through the second interface 131, pass through the purification unit 20, take away at least part of the adsorbed oil molecules in the purification unit 20, and enter the engine through the third interface 122 to participate in combustion. Or the fuel vapor purified by the purification unit 20 in the installation space 11 can also directly enter the engine through the third interface 122 to participate in combustion.

[0054] Specifically, when the engine is running, the vehicle control unit will control the corresponding valve to open, allowing the adsorbed fuel vapor and possibly mixed external air in the carbon canister device 100 to enter the engine through the third interface 122 to participate in combustion, thereby realizing the reuse of fuel vapor and reducing the emission of harmful substances.

[0055] In some embodiments of the present invention, the carbon canister device 100 may further include: a second filter element 16, the second filter element 16 is disposed in the installation space 11 and located between the purification unit 20 and the third interface 122, and the second filter element 16 covers the third interface 122.

[0056] Among them, the second filter element 16 can be made of non-woven fabric material. The non-woven fabric material has good filtering performance, air permeability, water permeability, corrosion resistance and wear resistance. It is disposed in the installation space 11 and located between the purification unit 20 and the third interface 122. The second filter element 16 covers the third interface 122, which can prevent the activated carbon powder in the purification unit 20 from entering the engine, thereby avoiding adverse effects on the normal operation of the engine system caused by the activated carbon powder. And the air permeability and water permeability of the non-woven fabric ensure that while preventing the activated carbon powder from entering the fuel tank, it will not overly impede the flow of fuel vapor into the engine, so as to realize the reuse of fuel vapor. In addition, the corrosion resistance and wear resistance of the non-woven fabric also enable it to maintain stable performance in various harsh working environments, extend the service life of the second filter element 16, and reduce the maintenance cost.

[0057] Further, as Figure 2As shown, a baffle 30 may be provided at the middle position of the end wall of the first end housing 12 facing the purification unit 20. The first filter element 15 and the second filter element 16 are respectively installed on both sides of the baffle 30. A groove 32 corresponding to the baffle 30 may be formed at one end of the purification unit 20 facing the first end housing 12. The baffle 30 is inserted into the groove 32 to separate at least part of the purification unit 20. For example, the part of the purification unit 20 close to the first interface 121 and the third interface 122 is separated, so as to prevent the fuel vapor that has just entered the installation space 11 through the first interface 121 and has not been adsorbed by the purification unit 20 from directly entering the engine through the third interface 122. Furthermore, the risk of impurities in the fuel vapor entering the engine can be effectively reduced, which is beneficial to reducing the risk of engine damage.

[0058] In some embodiments of the present invention, the carbon canister device 100 may further include: a pressing plate 17 and an elastic member 18. Both the pressing plate 17 and the elastic member 18 are located in the installation space 11. The pressing plate 17 is located between the elastic member 18 and the purification unit 20, and the elastic member 18 is compressed between the pressing plate 17 and the second end housing 13.

[0059] Among them, the pressing plate 17 may be made of a metal material, and through holes may be provided on the pressing plate 17 to ensure gas circulation. The elastic member 18 may be configured as a spring. Both the pressing plate 17 and the elastic member 18 are located in the installation space 11. The pressing plate 17 is located between the elastic member 18 and the purification unit 20, and the elastic member 18 is compressed between the pressing plate 17 and the second end housing 13. Through the cooperation of the pressing plate 17, the elastic member 18, and the second end housing 13, and under the elastic force of the elastic member 18, the purification unit 20 can be pressed against the inside of the housing 10 to ensure the stable position of the purification unit 20 in the installation space 11 and prevent it from shifting due to vibration or impact. It can also adapt to the vibration and temperature changes during operation through the elastic force of the elastic member 18, thereby maintaining the stability and reliability of the carbon canister device 100.

[0060] Furthermore, as Figure 1 shown, a limiting structure 31 may be provided on the side of the pressing plate 17 facing the elastic member 18. One end of the elastic member 18 may be installed in the limiting structure 31. The limiting structure 31 may be arranged along the circumferential direction of the elastic member 18 to limit the circumferential direction of the elastic member 18, effectively reducing the risk of circumferential crosstalk displacement of the elastic member 18, and further improving the safety and reliability of the carbon canister device 100.

[0061] In some embodiments of the present invention, the carbon canister device 100 may further include: an elastic filter element 19, and the elastic filter element 19 is arranged between the purification unit 20 and the pressing plate 17.

[0062] Among them, the elastic filter element 19 can be made of sponge material, and the elastic filter element 19 is arranged between the purification unit 20 and the pressing plate 17. The sponge material has good elasticity and can quickly return to its original state after being compressed, so that the elastic filter element 19 can provide stable support between the purification unit 20 and the pressing plate 17, and can also adapt to the small displacements caused by vibration or temperature changes. Moreover, the sponge material also has good filtering performance and air permeability to ensure that the toner particles in the purification unit 20 will not flow to the external environment through the elastic filter element 19 and can ensure that the purified fuel vapor can flow to the external environment through the elastic filter element 19, thereby maintaining the normal operation of the carbon canister device 100.

[0063] The vehicle according to the embodiment of the present invention includes the carbon canister device 100 of the above embodiment, which can change the volume of the carbon canister device 100 so that the carbon canister device 100 can accommodate fuel tanks of different volumes and can also reduce the development cost of the carbon canister device 100.
