[0003] A vehicle is usually provided with an inflatable mechanism that needs to be inflated and a gas storage device for storing gas. The gas storage device usually includes components such as a gas tank, a gas extraction mechanism and a connecting mechanism. The gas extraction mechanism draws gas into the gas tank, and the connecting mechanism fills the gas in the gas tank into the inflatable mechanism. However, the volume of the gas tank is usually large and requires a large space, which increases the difficulty of arranging other components of the vehicle and causes the cost and weight of the entire vehicle to increase.

[0004] Application Contents

[0005] The purpose of the embodiments of the present application is to provide a gas storage device and a vehicle, including but not limited to solving the problem in the related art that the large volume of the gas tank causes an increase in the cost and weight of the entire vehicle.

[0006] The technical solution adopted in the embodiment of this application is:

[0007] In a first aspect, an air storage device is provided, which is suitable for use in a vehicle. An air storage chamber is constructed in the vehicle frame. The air storage device includes an air suction mechanism and a connecting mechanism. The air suction mechanism is connected to the air storage chamber. The air suction mechanism is used to draw gas into the air storage chamber. The connecting mechanism connects the air storage chamber and the mechanism to be inflated so that the gas in the air storage chamber can enter the mechanism to be inflated.

[0008] The gas storage device of the embodiment of the present application has a gas storage cavity in the vehicle frame structure, so that the vehicle frame can be used as a gas storage component, thereby eliminating the gas tank, saving a lot of space in the vehicle, and reducing the difficulty of arranging other components in the vehicle, which is conducive to reducing the weight of the entire vehicle and reducing the cost of parts; at the same time, it can also provide more installation space for the vehicle's battery or other systems, optimizing the vehicle's layout space.

[0009] In one embodiment, the frame is a subframe.

[0010] By adopting the technical solution of this embodiment, the subframe is usually hollow inside, and the internal hollow structure of the subframe is used as the air storage chamber. Its structure is simple and easy to process and manufacture. In addition, the air storage capacity of the internal hollow structure of the subframe is also greater than the air storage capacity of the air storage tank, which can increase the air storage capacity of the air storage device, which is beneficial to improving the performance of the air spring, and thus is beneficial to the suspension adjustment and vibration isolation of the vehicle.

[0011] In one embodiment, the frame includes a plurality of side strips connected end to end, at least one of the side strips is hollow inside and forms a first hollow cavity, and at least one first hollow cavity forms an air storage cavity.

[0012] By adopting the technical solution of this embodiment, the hollow cavity inside the side strip is used as the air storage cavity, which can fully utilize the space inside the frame, improve the space utilization rate of the vehicle, reduce cost and weight, and facilitate processing and manufacturing.

[0013] In one embodiment, each side strip is provided with a first hollow cavity, and the first hollow cavities are connected end to end to form an air storage cavity.

[0014] By adopting the technical solution of this embodiment, the first hollow cavities of all the side strips are connected to form a larger air storage cavity, which is beneficial to increasing the air storage capacity of the air storage device, thereby improving the performance of the air spring and the performance of the vehicle; in addition, the shape of the annular cavity structure formed by the first hollow cavities being connected end to end in sequence is compatible with the shape of the overall closed frame structure of the vehicle frame, which can further increase the volume of the air storage cavity, thereby increasing the air storage capacity of the air storage device.

[0015] In one embodiment, at least a portion of at least one of the side strips has a rectangular or circular cross-section.

[0016] By adopting the technical solution of this embodiment, the side strips have a rectangular or circular cross section, and their structure is regular, making them easy to process and manufacture.

[0017] In one embodiment, at least one side strip is configured with a notch, and at least a portion of the communication mechanism is located in the notch; and / or at least a portion of the air extraction mechanism is located in the notch.

[0018] By adopting the technical solution of this embodiment, at least part of the connecting mechanism is located in the gap, so that the connecting mechanism is integrated with the frame, the vehicle's structure is more compact, the vehicle's space utilization is better, and it is beneficial to reducing the cost and quality of the vehicle; at least part of the exhaust mechanism is located in the gap, so that the exhaust mechanism is integrated with the frame, the vehicle's structure is more compact, the vehicle's space utilization is better, and it is beneficial to reducing the cost and quality of the vehicle.

[0019] In one embodiment, the notch is provided near the connection between two adjacent side strips.

[0020] By adopting the technical solution of this embodiment, the structural strength of the connection between the two adjacent side strips is good, and the notch is set there, so that the frame still has good structural strength, and can also play a good supporting and fixing role for the air storage device, which is beneficial to improving the performance of the vehicle; in addition, in the vehicle, there are fewer components arranged at the connection between the two adjacent side strips, which is also convenient for the installation of the connecting mechanism and the air extraction mechanism, which is beneficial to improving the space utilization of the vehicle, and can also reduce the difficulty of arranging the vehicle components, which is beneficial to reducing the cost and weight of the vehicle.

[0021] In one embodiment, the surface of the side strip is recessed toward the first hollow cavity to form a notch.

[0022] By adopting the technical solution of this embodiment, the notch is formed by the depression on the surface of the side strip, and the inner wall of the notch separates the notch from the first hollow cavity. That is, the setting of the notch has no effect or little effect on the sealing of the first hollow cavity, and the risk of gas in the air storage cavity leaking from the notch is small, and the air storage effect of the frame is good; at the same time, there is no need to set a sealing structure at the notch, which makes the operation of installing the connecting mechanism and the air extraction mechanism in the notch simpler.

[0023] In one embodiment, the inner wall of the notch is constructed with a connecting port for communicating with the first hollow cavity; when at least part of the connecting mechanism is located in the notch, the connecting mechanism seals the connecting port; when at least part of the exhaust mechanism is located in the notch, the exhaust mechanism seals the connecting port.

[0024] By adopting the technical solution of this embodiment, the notch can be directly obtained by mechanical processing on the side strip, and the processing and manufacturing are simple.

[0025] In one embodiment, one of the two oppositely arranged side strips is connected to a first connecting strip, and the other is connected to a second connecting strip. The first connecting strip and the second connecting strip are located on the same side of the frame. A third connecting strip is connected between the end of the first connecting strip facing away from the side strip and the end of the second connecting strip facing away from the side strip. The first connecting strip, the second connecting strip, the third connecting strip and the side strips are jointly arranged to form a accommodating space for accommodating components.

[0026] By adopting the technical solution of this embodiment, the components can be installed in the accommodating space, making full use of the space formed by the frame, which is beneficial to improving the space utilization of the vehicle, reducing the difficulty of arranging the vehicle components, and helping to reduce the cost and weight of the vehicle; in addition, the first connecting bar, the second connecting bar and the third connecting bar can also support the components, and the components have good stability and reliability in the accommodating space, which is beneficial to improving the reliability of the vehicle.

[0027] In one embodiment, at least one of the first connecting bar, the second connecting bar and the third connecting bar is hollow inside and forms a second hollow cavity, and the first hollow cavity is communicated with the second hollow cavity to form an air storage cavity.

[0028] By adopting the technical solution of this embodiment, the setting of the second hollow cavity can further increase the volume of the air storage cavity, which is beneficial to improving the air storage capacity of the air storage device, and is also beneficial to improving the space utilization of the vehicle, improving the performance of the air spring, and improving the comfort of the vehicle.

[0029] In one embodiment, the connecting mechanism includes a distribution valve, which connects the gas storage chamber, the gas extraction mechanism and the mechanism to be inflated. The distribution valve is used to distribute the gas drawn into the gas extraction mechanism to the gas storage chamber and to distribute the gas in the gas storage chamber to the mechanism to be inflated.

[0030] By adopting the technical solution of this embodiment and setting the distribution valve, the pipeline connection between the air storage chamber, the air extraction mechanism and the mechanism to be inflated is simpler, which is also beneficial to the integration of the pipeline, which is beneficial to improving space utilization and reducing the production cost of the vehicle.

[0031] In one embodiment, the communication mechanism further includes a connector, which is connected to the vehicle frame and connects the distribution valve and the gas storage chamber, and is used for allowing gas to flow into and out of the gas storage chamber.

[0032] By adopting the air storage device of this embodiment, the connector serves as both the air inlet component and the air outlet component of the air storage chamber, making the pipeline connection between the distribution valve and the air storage chamber simpler, and the overall structure of the frame and the air storage device is compact, which also facilitates the assembly of the air storage device and the frame, and helps to reduce the production cost of the vehicle.

[0033] In one embodiment, the air extraction mechanism includes an air extraction member and a filter member for filtering out impurities in the gas. The air extraction port of the air extraction member is connected to the filter member, and the air outlet of the air extraction member is connected to the air storage chamber.

[0034] By adopting the technical solution of this embodiment, the filter element can filter out impurities in the gas, thereby reducing the damage caused by the impurities to the air extraction element and the subsequent inflatable mechanism.

[0035] In one embodiment, the structure to be inflated comprises an air spring.

[0036] By adopting the technical solution of this embodiment, the frame is used as an air storage component and is used to inflate the air spring, which can eliminate the air tank, thereby saving the internal space of the vehicle, thereby reducing the difficulty of arranging other components and helping to reduce the cost and weight of the vehicle.

[0037] In a second aspect, a vehicle is provided, comprising the gas storage device according to the above embodiment.

[0038] By adopting the technical solution of this embodiment, the vehicle can use the frame as the gas storage component, thereby eliminating the gas tank, saving a lot of space, facilitating the arrangement of other components in the vehicle, and helping to reduce the cost and weight of the vehicle.

[0062] In a vehicle, an air storage device is a device used to supply air to a mechanism to be inflated in the vehicle. Usually, the air storage device usually includes components such as an air tank, an air extraction mechanism and a connecting mechanism. The air extraction mechanism draws gas into the air tank, and the connecting mechanism fills the gas in the air tank into the mechanism to be inflated. Specifically, in order to improve the comfort of the vehicle, an air spring is usually provided at the bottom of the vehicle. The air storage device inflates the air spring, which can change the hardness and elastic coefficient of the air spring, reduce the force applied by the road surface to the vehicle body, and cushion the impact of the road surface. However, the volume of the air tank is usually large, which requires a larger space in the vehicle, increases the difficulty of arranging other components of the vehicle, and causes the cost and weight of the entire vehicle to increase.

[0063] Based on this, in order to reduce the cost and weight of the entire vehicle, the gas storage device of the embodiment of the present application constructs an air storage chamber in the frame, and draws gas into the air storage chamber through a vacuum mechanism for storage, and then uses a connecting mechanism to fill the gas in the air storage chamber into the mechanism to be inflated, thereby realizing the inflation of the mechanism to be inflated; and the air storage chamber of the frame can be used as an air storage space, that is, the frame serves as a gas storage component, thereby eliminating the air storage tank, and thus saving a lot of space in the vehicle, and reducing the difficulty of arranging other components in the vehicle, which is conducive to reducing the weight of the entire vehicle and reducing the cost of parts; at the same time, it can also provide more installation space for the vehicle's battery or other systems, optimizing the vehicle's layout space.

[0064] As shown in FIG2 , the gas storage device 100 disclosed in the embodiment of the present application may refer to a device for storing gas and capable of inflating a mechanism to be inflated in a vehicle 1000 . Specifically, the mechanism to be inflated may be an air spring.

[0065] As shown in FIG1 , the vehicle 1000 disclosed in the embodiment of the present application may be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc.

[0066] As shown in Figures 2 to 4, in one embodiment of the present application, a gas storage device 100 is provided, which is suitable for use in a vehicle 1000. A gas storage chamber 2001 is constructed in the frame 200 of the vehicle 1000. The gas storage device 100 includes a gas suction mechanism 110 and a connecting mechanism 120. The gas suction mechanism 110 is connected to the gas storage chamber 2001. The gas suction mechanism 110 is used to draw gas into the gas storage chamber 2001. The connecting mechanism 120 connects the gas storage chamber 2001 and the mechanism to be inflated, so that the gas in the gas storage chamber 2001 can enter the mechanism to be inflated.

[0067] When vehicle 1000 employs a non-load-bearing body, the frame 200 of vehicle 1000 may refer to the frame 200 on which components (e.g., battery 1100, engine, transmission, etc.) are mounted and fixed. When vehicle 1000 employs a load-bearing body, the frame 200 of vehicle 1000 may refer to at least a portion of the floor, side door frames, and roof of the vehicle 1000. Furthermore, the frame 200 of vehicle 1000 may also refer to the subframe 201 of vehicle 1000. Subframe 201 may refer to the framework of the front and rear axles of vehicle 1000, supporting the front and rear axles and the suspension.

[0068] The gas storage chamber 2001 may refer to a cavity formed within the vehicle frame 200, which is in a sealed state to achieve the function of storing gas. The gas storage chamber 2001 is in a sealed state when storing gas to reduce gas leakage, thereby effectively storing gas. Specifically, in actual applications, in order to reduce the weight of the vehicle 1000, the vehicle frame 200 is usually hollow, that is, a sealed hollow cavity can be formed inside the vehicle frame 200, and this hollow cavity can serve as the gas storage chamber 2001. Directly utilizing the hollow cavity inside the vehicle frame 200 as the gas storage chamber 2001 eliminates the need for additional processing to produce the gas storage chamber 2001, thereby reducing the difficulty of manufacturing the vehicle frame 200 and fully utilizing the space inside the frame 200, thereby improving the space utilization rate of the vehicle 1000 and reducing the manufacturing cost and parts cost of the vehicle 1000.

[0069] The gas extraction mechanism 110 may refer to a mechanism for extracting gas into the gas storage chamber 2001; the gas extraction mechanism 110 may include components such as a gas extraction pump; and the gas may refer to air, inert gas, etc.

[0070] The connecting mechanism 120 may be a mechanism that connects the gas storage chamber 2001 and the structure to be inflated, and the connecting mechanism 120 allows the gas in the gas storage chamber 2001 to pass through and enter the structure to be inflated, thereby inflating the structure to be inflated. The connecting mechanism 120 may include components such as a pipe and an air pump.

[0071] The air extraction mechanism 110 is in communication with the air storage chamber 2001. It is understood that the air outlet of the air extraction mechanism 110 is in communication with the air storage chamber 2001. The gas extracted by the air extraction mechanism 110 can enter the air storage chamber 2001 through the air outlet, thereby inflating the air storage chamber 2001 and providing an air source for subsequent mechanisms to be inflated. Specifically, the air outlet of the air extraction mechanism 110 can be directly in communication with the air storage chamber 2001 via a pipe.

[0072] The connecting mechanism 120 connects the air storage chamber 2001 and the mechanism to be inflated. It can be understood that the air storage chamber 2001 and the mechanism to be inflated are connected through the connecting mechanism 120, so that the gas in the air storage chamber 2001 can enter the mechanism to be inflated through the connecting mechanism 120, thereby realizing the inflation of the mechanism to be inflated; specifically, the connecting mechanism 120 may include a pipeline, that is, the air storage chamber 2001 is connected to the mechanism to be inflated through the pipeline, and the gas in the air storage chamber 2001 can enter the mechanism to be inflated along the pipeline.

[0073] When the gas storage device 100 of the embodiment of the present application is in use, the air extraction mechanism 110 can draw gas into the gas storage chamber 2001 of the frame 200 for storage. When the mechanism to be inflated needs to be inflated, the connecting mechanism 120 connects the gas storage chamber 2001 and the mechanism to be inflated, and the gas in the gas storage chamber 2001 can enter the mechanism to be inflated, thereby achieving inflation of the mechanism to be inflated.

[0074] The gas storage device 100 of the embodiment of the present application and the vehicle frame 200 are constructed with a gas storage cavity 2001, so that the vehicle frame 200 can be used as a gas storage component, thereby eliminating the need for a gas tank, saving a large amount of space in the vehicle 1000, and reducing the difficulty of arranging other components in the vehicle 1000, which is conducive to reducing the weight of the entire vehicle and reducing the cost of parts; at the same time, it can also provide more installation space for the battery 1100 or other systems of the vehicle 1000, thereby optimizing the layout space of the vehicle 1000.

[0075] In another embodiment of the present application, as shown in FIG. 2 , the vehicle frame 200 is a sub-frame 201 .

[0076] By adopting the technical solution of this embodiment, the subframe 201 is usually hollow inside, and the internal hollow structure of the subframe 201 is used as the air storage chamber 2001. Its structure is simple and easy to process and manufacture. In addition, the air storage capacity of the internal hollow structure of the subframe 201 is also greater than the air storage capacity of the air storage tank, which can increase the air storage capacity of the air storage device 100, which is beneficial to improving the performance of the air spring, and thus facilitating the suspension adjustment and vibration isolation of the vehicle 1000.

[0077] In another embodiment of the present application, as shown in Figures 5 to 9, the frame 200 includes a plurality of side strips 210 connected end to end, at least one side strip 210 is hollow inside and forms a first hollow cavity 211, and at least one first hollow cavity 211 forms an air storage chamber 2001.

[0078] The vehicle frame 200 is a closed frame structure that facilitates component installation and reduces the weight of the vehicle 1000. The side bars 210 may refer to a side frame bar of the frame structure. Multiple side bars 210 are connected end to end to form a closed frame structure. Adjacent side bars 210 may be connected by, but are not limited to, bolting, bonding, clamping, riveting, welding, or integral molding. Integrally molded refers to manufacturing using an integrated process such as extrusion, injection molding, or die-casting. The number of side bars 210 may be, but is not limited to, three, four, five, or six.

[0079] The side bars 210 have a hollow structure, which can reduce the weight of the vehicle 1000. That is, the interior of the side bars 210 is hollow. At least one side bar 210 is hollow and forms a first hollow cavity 211. It is understood that the number of hollow side bars 210 in the vehicle frame 200 can be one, two, three, or more than four. The hollow cavity formed by the hollow interior of the side bars 210 is the first hollow cavity 211. Specifically, the side bars 210 can be hollow profiles. The side bars 210 can be made of steel, aluminum alloy, plastic steel, or other materials. Multiple side bars 210 can be made of the same material or different materials, and the structures of the multiple side bars 210 can be the same or different.

[0080] At least one first hollow cavity 211 forms an air storage cavity 2001. It can be understood that the number of first hollow cavities 211 for storing gas can be one, two, three or four; wherein, the first hollow cavities 211 can be interconnected or not interconnected; when the first hollow cavities 211 are interconnected, the interconnected first hollow cavities 211 can form the air storage cavity 2001 together, or one first hollow cavity 211 that is not connected to other first hollow cavities 211 can be used as the air storage cavity 2001, and the specific setting can be based on actual needs; or, when all the first hollow cavities 211 are not connected, one first hollow cavity 211 is an air storage cavity 2001; wherein, a part of the first hollow cavities 211 can be used as the air storage cavity 2001, and another part of the first hollow cavities 211 cannot be used as the air storage cavity 2001, or all the first hollow cavities 211 can be used as the air storage cavity 2001.

[0081] By adopting the technical solution of this embodiment, the hollow cavity inside the side strip 210 is used as the air storage chamber 2001, so that the space inside the frame 200 can be fully utilized, which is beneficial to improving the space utilization rate of the vehicle 1000, reducing costs and weight, and facilitating processing and manufacturing.

[0082] In another embodiment of the present application, as shown in Figures 5 to 9 , each side strip 210 is provided with a first hollow cavity 211 , and the first hollow cavities 211 are connected end to end to form an air storage cavity 2001 .

[0083] It can be understood that each side strip 210 is hollow, that is, each side strip 210 is provided with a first hollow cavity 211, and the annular cavity structure formed by connecting the first hollow cavities 211 end to end in sequence is the air storage cavity 2001, and each first hollow cavity 211 is connected to form a larger air storage cavity 2001. It should be noted that the connection between the two adjacent side strips 210 needs to be sealed to reduce leakage and improve the air storage performance of the air storage cavity 2001; specifically, the two adjacent side strips 210 can be connected by welding, sealing strips, sealants, one-piece molding, etc.

[0084] By adopting the technical solution of this embodiment, the first hollow cavities 211 of all the side strips 210 are connected to form a larger air storage cavity 2001, which is beneficial to increasing the air storage capacity of the air storage device 100, thereby improving the performance of the air spring and the performance of the vehicle 1000; in addition, the shape of the annular cavity structure formed by the first hollow cavities 211 being connected end to end in sequence is compatible with the shape of the overall closed frame structure of the frame 200, which can further increase the volume of the air storage cavity 2001, thereby increasing the air storage capacity of the air storage device 100.

[0085] In another embodiment, the first hollow cavities 211 of two adjacent side strips 210 may not be directly connected, but may be connected through another connecting pipe; this can reduce the difficulty of sealing the connection between the adjacent side strips 210.

[0086] In another embodiment of the present application, as shown in combination with FIG. 6 and FIG. 7 , at least a portion of the cross section of at least one side strip 210 is rectangular.

[0087] It is understood that the number of the side strips 210 with a rectangular cross section is one, two, three, or more than four, that is, a portion of the side strips 210 has a rectangular cross section, while another portion of the side strips 210 has a cross section of other shapes, such as a circle, an ellipse, a triangle, etc., or all of the side strips 210 have a rectangular cross section. The rectangular cross section of the side strip 210 may be a section of the side strip 210 with a rectangular cross section, while the other sections have a circular, polygonal, or other shape; or the entire side strip 210 has a rectangular cross section. The cross section of the side strip 210 may refer to a cross section perpendicular to the axial direction of the side strip 210, which is rectangular or nearly rectangular. For example, the edges of the side strip 210 are chamfered to achieve a smooth transition between adjacent side walls of the side strip 210, thereby improving the structural strength of the side strip 210.

In this way, the closed space formed by the side strips 210 and the space formed by the U-shaped structure together form the accommodating space 2002. Specifically, the first connecting bar 220, the second connecting bar 230 and the third connecting bar 240 can be made of hollow profiles. The materials of the first connecting bar 220, the second connecting bar 230 and the third connecting bar 240 can be made of steel, aluminum alloy, plastic steel and other materials.

[0104] At least part of the connecting mechanism 120 is located in the notch 212; and / or, at least part of the air extraction mechanism 110 is located in the notch 212. It can be understood that at least part of the connecting mechanism 120 is located in the notch 212, and the air extraction mechanism 110 is located outside the notch 212; or, at least part of the air extraction mechanism 110 is located in the notch 212, and the connecting mechanism 120 is located outside the notch 212; or, at least part of the connecting mechanism 120 is located in the notch 212, and at least part of the air extraction mechanism 110 is located in the notch 212, wherein the connecting mechanism 120 and the air extraction mechanism 110 can be located in the same notch 212 or in different notches 212.

[0105] By adopting the technical solution of this embodiment, at least a portion of the connecting mechanism 120 is located in the notch 212, so that the connecting mechanism 120 is integrated with the frame 200, the structural compactness of the vehicle 1000 is better, the space utilization rate of the vehicle 1000 is better, which is beneficial to reducing the cost and quality of the vehicle 1000; at least a portion of the air extraction mechanism 110 is located in the notch 212, so that the air extraction mechanism 110 is integrated with the frame 200, the structural compactness of the vehicle 1000 is better, the space utilization rate of the vehicle 1000 is better, which is beneficial to reducing the cost and quality of the vehicle 1000.

[0106] In another embodiment of the present application, as shown in FIG. 5 , the notch 212 is provided near the connection between two adjacent side strips 210 .

[0107] It is understandable that a notch 212 is provided at the end of the side strip 210 close to the adjacent side strip 210 .

[0108] By adopting the technical solution of this embodiment, the structural strength of the connection between the two adjacent side strips 210 is good, and the notch 212 is set there, so that the frame 200 still has good structural strength, and can also play a good supporting and fixing role for the gas storage device 100, which is beneficial to improving the performance of the vehicle 1000; in addition, in the vehicle 1000, there are fewer components arranged at the connection between the two adjacent side strips 210, which is also convenient for the installation of the connecting mechanism 120 and the air extraction mechanism 110, which is beneficial to improving the space utilization of the vehicle 1000, and can also reduce the difficulty of arranging the components of the vehicle 1000, which is beneficial to reducing the cost and weight of the vehicle 1000.

[0109] In another embodiment of the present application, the surface of the side strip 210 is recessed toward the first hollow cavity 211 to form a notch 212 .

[0110] It can be understood that the surface of the side strip 210 is recessed toward the first hollow cavity 211 therein, thereby forming a notch 212 .

[0111] By adopting the technical solution of this embodiment, the notch 212 is formed by a depression on the surface of the side strip 210, and the inner wall of the notch 212 separates the notch 212 and the first hollow cavity 211. That is, the setting of the notch 212 has no effect or little effect on the sealing of the first hollow cavity 211, and the risk of gas in the air storage chamber 2001 leaking from the notch 212 is small; at the same time, there is no need to set a sealing structure at the notch 212, which makes the operation of installing the connecting mechanism 120 and the exhaust mechanism 110 in the notch 212 simpler.

[0112] In another embodiment of the present application, as shown in Figure 4, the inner wall of the notch 212 is constructed with a connecting port 2121, which is used to communicate with the first hollow cavity 211; when at least part of the connecting mechanism 120 is located in the notch 212, the connecting mechanism 120 seals the connecting port 2121; when at least part of the exhaust mechanism 110 is located in the notch 212, the exhaust mechanism 110 seals the connecting port 2121.

[0113] The connecting opening 2121 may refer to an opening formed on the inner wall of the notch 212 and connecting the notch 212 and the first hollow cavity 211 . Specifically, the notch 212 is obtained by removing part of the outer wall of the side strip 210 , and the edge of the notch 212 is surrounded to form the connecting opening 2121 .

[0114] When at least part of the connecting mechanism 120 is located in the notch 212, the connecting mechanism 120 seals the connecting opening 2121. It can be understood that when the connecting mechanism 120 is located in the notch 212, the connecting mechanism 120 is sealed to the side strip 210, thereby sealing the connecting opening 2121. Specifically, the connecting mechanism 120 and the connecting opening 2121 can be sealed by means of sealant, sealing ring, welding, etc.

[0116] By adopting the technical solution of this embodiment, the notch 212 can be directly obtained by mechanical processing on the side strip 210, and the processing and manufacturing are simple.

[0117] In another embodiment of the present application, in combination with Figures 2, 3, 10 and 11, the connecting mechanism 120 includes a distribution valve 121, which connects the air storage chamber 2001, the air extraction mechanism 110 and the mechanism to be inflated. The distribution valve 121 is used to distribute the gas drawn into the air extraction mechanism 110 to the air storage chamber 2001 and to distribute the gas in the air storage chamber 2001 to the mechanism to be inflated.

[0118] The distribution valve 121 may refer to a valve that can distribute gas to different destinations. Specifically, the distribution valve 121 is provided with multiple channels. After the gas storage chamber 2001, the gas extraction mechanism 110, and the mechanism to be inflated are all connected to the distribution valve 121, a channel is connected between the gas storage chamber 2001 and the gas extraction mechanism 110. By controlling the opening and closing of the channel, the gas storage chamber 2001 can be inflated. Similarly, there is also a channel connected between the mechanism to be inflated and the gas storage chamber 2001. By controlling the opening and closing of the channel, the gas storage chamber 2001 can be deflated and stored, as well as the mechanism to be inflated can be inflated. In particular, in the case of multiple mechanisms to be inflated, the multiple channels in the distribution valve 121 can be utilized. The gas storage chamber 2001 can be connected to the multiple mechanisms to be inflated through the multiple channels, thereby inflating the multiple mechanisms to be inflated. Specifically, it is also possible to simultaneously inflate multiple mechanisms to be inflated or to inflate each mechanism to be inflated individually.

[0119] By adopting the technical solution of this embodiment, the distribution valve 121 is set, which makes the pipeline connection between the air storage chamber 2001, the air extraction mechanism 110 and the mechanism to be inflated simpler, is also conducive to the integration of the pipeline, and is conducive to improving space utilization and reducing the production cost of the vehicle 1000.

[0120] In another embodiment of the present application, the connecting mechanism 120 further includes a connector 122 , which is connected to the vehicle frame 200 . The connector 122 connects the distribution valve 121 and the gas storage chamber 2001 . The connector 122 is used to allow gas to flow into and out of the gas storage chamber 2001 .

[0121] The connector 122 may refer to a device connecting the distribution valve 121 and the gas storage chamber 2001, and the connector 122 is used for allowing gas to flow into and out of the gas storage chamber 2001, that is, the connector 122 serves as both an air inlet component of the gas storage chamber 2001 and an air outlet component of the gas storage chamber 2001, that is, the gas drawn in by the exhaust mechanism 110 flows into the gas storage chamber 2001 through the distribution valve 121 and then through the connector 122, and when the mechanism to be inflated needs to be inflated, the gas in the gas storage chamber 2001 can flow into the distribution valve 121 through the connector 122, and then flow into the mechanism to be inflated through the distribution valve 121, that is, the distribution valve 121 and the connector 122 can be connected by a pipeline, so that the inflation and deflation of the gas storage chamber 2001 can be realized; specifically, the connector 122 may refer to a pipe interface or a gas nozzle and other components. The connector 122 can be disposed inside the notch 212 or outside the notch 212 , and the specific location thereof can be determined according to actual needs and is not limited herein.

[0122] By adopting the air storage device 100 of this embodiment, the connector 122 serves as both an air inlet component and an air outlet component of the air storage chamber 2001, making the pipeline connection between the distribution valve 121 and the air storage chamber 2001 simpler. The overall structure of the frame 200 and the air storage device 100 is compact, which also facilitates the assembly of the air storage device 100 and the frame 200, and helps to reduce the production cost of the vehicle 1000.

[0123] Of course, in other embodiments, the number of connectors 122 can be multiple, and one part can be used as the air inlet component of the air storage chamber 2001, and the other part can be set separately as the air outlet component of the air storage chamber 2001. Among them, the air storage chamber 2001 can also be provided with multiple air inlet components and multiple air outlet components. The specific selection can be based on actual needs and is not limited here.

[0124] In another embodiment of the present application, in combination with Figures 2, 3, 10 and 11, the air extraction mechanism 110 includes an air extraction member 112 and a filter member 111 for filtering out impurities in the gas, the air extraction port of the air extraction member 112 is connected to the filter member 111, and the air outlet of the air extraction member 112 is connected to the air storage chamber 2001.

[0126] The filter element 111 may refer to a component capable of filtering out impurities in a gas. When the gas is air, the filter element 111 is an air filter element.

[0127] The air extraction port of the air extraction member 112 is connected to the filter member 111, and the air outlet of the air extraction member 112 is connected to the air storage chamber 2001. It is understood that when the air extraction member 112 is performing air extraction, the gas first passes through the filter member 111 to filter out impurities in the gas, and then enters the air storage chamber 2001 for storage under the air extraction force of the air extraction member 112. Specifically, the filter member 111 and the air extraction member 112 can be connected through a pipeline, or the air outlet of the filter member 111 and the air extraction port of the air extraction member 112 can be directly connected.

[0128] By adopting the technical solution of this embodiment, the filter element 111 can filter out impurities in the gas, thereby reducing the damage caused by the impurities to the air extraction element 112 and the subsequent inflatable mechanism.

[0129] In another embodiment of the present application, the mechanism to be inflated includes an air spring.

[0130] An air spring is a non-metallic spring that uses its internal cavity to hold air and utilizes the compressibility of air to achieve elasticity. Specifically, the air extraction mechanism 110 draws air into the air storage chamber 2001 to store air. The air in the air storage chamber 2001 then flows through the connecting mechanism 120 into the internal cavity of the air spring, thereby inflating the air spring.

[0131] By adopting the technical solution of this embodiment, the frame 200 is used as an air storage component and is used to inflate the air spring, which can eliminate the air tank, thereby saving the internal space of the vehicle 1000, thereby reducing the difficulty of arranging other components, and helping to reduce the cost and weight of the vehicle 1000.

[0132] The present application is described below by taking the inflatable mechanism being an air spring as an example.

The subframe 201 includes a first connecting bar 220, a second connecting bar 230, a third connecting bar 240 and four side bars 210. The four side bars 210 are connected end to end to form a rectangular closed frame structure. The upper end of the first connecting bar 220 and the upper end of the second connecting bar 230 are respectively connected to the middle of the two side bars 210 on the left and right sides. The left end of the connecting bar 240 is connected to the lower end of the first connecting bar 220, and the right end of the fourth connecting bar is connected to the lower end of the second connecting bar 230. The first connecting bar 220, the second connecting bar 230 and the third connecting bar 240 form a U-shaped structure with the opening facing upward. The motor 1300 of the vehicle 1000 can be placed in the accommodating space 2002 formed by the rectangular closed frame structure and the U-shaped structure, and the U-shaped structure can support the motor 1300, thereby improving the reliability of the fixation of the motor 1300.

[0134] In this embodiment, the first connecting bar 220, the second connecting bar 230, the third connecting bar 240 and the four side bars 210 are all hollow, and the hollow cavity in the side bar 210 forms a first hollow cavity 211, and the hollow cavity in the first connecting bar 220, the hollow cavity in the second connecting bar 230, and the hollow cavity in the third connecting bar 240 are all second hollow cavities 221. The four first hollow cavities 211 are connected end to end and form an annular cavity, and the second hollow cavities 221 are connected in turn to form a U-shaped cavity. The annular cavity and the U-shaped cavity are connected and together form an air storage cavity 2001. The air storage cavity 2001 has a large volume and a large air storage capacity, which is beneficial to improving the performance of the air spring. Among them, the cross-section of the side strips 210 located on the left and right sides is rectangular, the cross-section of the side strips 210 located on the front and rear sides is circular, and the cross-sections of the first connecting strip 220, the second connecting strip 230 and the third connecting strip 240 are all rectangular. This design can take into account both the air storage capacity and the structural strength of the frame 200.

[0135] In this embodiment, the first connecting strip 220 and the side strip 210 on the left side are an integral structure, that is, the first connecting strip 220 and the side strip 210 on the left side are made by an integral molding process; the second connecting strip 230 and the side strip 210 on the right side are an integral structure, that is, the first connecting strip 220 and the side strip 210 on the left side are made by an integral molding process; the left and right ends of the third connecting strip 240 are sealedly connected to the first connecting strip 220 and the second connecting strip 230 respectively, the left and right ends of the side strip 210 on the front side are sealedly connected to the side strips 210 on the left and right sides respectively, and the left and right ends of the side strip 210 on the rear side are sealedly connected to the side strips 210 on the left and right sides respectively. The sealing connection method in this article can be welding, sealing strips or sealants. This design enables the subframe 201 to form a hollow sealing structure, and can reduce leakage and improve air storage capacity.

[0136] In this embodiment, the air storage device 100 includes an air extraction mechanism 110 and a connecting mechanism 120. The air extraction mechanism 110 includes a filter element 111, an air extraction element 112, a first pipe 113 and a second pipe 114. The connecting mechanism 120 includes a distribution valve 121, a connector 122, a third pipe 123 and a fourth pipe 124. A notch 212 is provided at the front end of the side strip 210 on the left side. The notch 212 passes through the side strip 210 up and down and forms a connecting port 2121 connecting the notch 212 and the air storage chamber 2001. The distribution valve 121 is installed in the notch 212 and can seal the connecting port 2121. The air extraction element 112 is fixed to the front end of the side strip 210 on the left side by a bracket 300. This arrangement has a compact structure, facilitates the arrangement of other components, and is also beneficial to reducing the production cost and weight of the vehicle 1000.

[0137] In this embodiment, the filter element 111 is connected to the air extraction port of the air extraction element 112 through a first pipe 113, and the air outlet of the air extraction element 112 is connected to the distribution valve 121 through a second pipe 114.

Usually, there are four air springs, and the four air springs are respectively arranged near the four wheels 1400 of the vehicle 1000. The air springs and the distribution valves 121 are connected one-to-one through four fourth pipes 124. In this way, the suction element 112 draws the air filtered by the filter element 111 into the air storage chamber 2001 in the subframe 201 through the distribution valve 121. When the air springs need to be inflated, the air stored in the air storage chamber 2001 enters the distribution valve 121 through the connector 122. The distribution valve 121 distributes the gas to the four fourth pipes 124, and the gas enters the four air springs along the fourth pipes 124 respectively, thereby realizing the air distribution of the four air springs.
