[0053] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0054] Embodiment 1

[0055] This embodiment relates to a gas cylinder installation structure, which has a relatively light overall weight, low cost, convenient individual installation and disassembly of each gas cylinder 5, convenient simultaneous installation and disassembly of multiple gas cylinders 5, and also convenient overall installation and disassembly of the gas cylinder installation structure.

[0056] Based on the above design concept, an exemplary structure of the gas cylinder installation structure in the application state of this embodiment is as Figure 1 andFigure 2 As shown, the gas cylinder installation structure of this embodiment is as Figure 4 shown. In terms of the overall structure, the gas cylinder installation structure of this embodiment includes an annular frame body, which is detachably connected to the vehicle body 12, and the gas cylinder 5 is detachably installed on the frame body.

[0057] Specifically, the frame body in this embodiment includes two cross beams 1 arranged oppositely, and two cross beam connection components 2 arranged oppositely. Both cross beams 1 extend along the first direction, and a gas cylinder installation portion 3 for installing the gas cylinder 5 is provided on each cross beam 1. The gas cylinder installation portions 3 on the two cross beams 1 are correspondingly arranged, so that the gas cylinder 5 can be installed between the two cross beams 1 through a set of correspondingly arranged gas cylinder installation portions 3.

[0058] In a preferred embodiment, the cross beam 1 is made of an existing tubular profile, which is convenient for processing and has good structural strength. The cross section of the tubular profile can be, for example, a "mouth" shape, a "day" shape, etc., as long as the structural strength can be guaranteed.

[0059] As Figure 4 and Figure 5 shown, each cross beam connection component 2 includes a longitudinal beam 201 extending along the second direction, and connection beams 202 respectively arranged at both ends of the longitudinal beam 201. Each cross beam connection component 2 is detachably connected to the two cross beams 1 respectively through the connection beams 202 at both ends. In this way, both ends of each cross beam 1 can be detached from the cross beam connection component 2, and by disassembling and assembling the two cross beams 1, all the gas cylinders 5 installed between the two cross beams 1 can be disassembled and assembled, which is convenient for disassembly and assembly.

[0060] It should be noted that in a preferred embodiment, the aforementioned first direction and the second direction are arranged crosswise. In this embodiment, the first direction and the second direction are preferably arranged orthogonally, so that the frame body is convenient to be arranged on the vehicle body 12. In addition, when the first direction is the vehicle length direction, the second direction is the vehicle width direction, and when the first direction is the vehicle width direction, the second direction is the vehicle length direction.

[0061] It should also be noted that the frame body in this embodiment is installed on the vehicle body 12 through the cross beam connection components 2 on both sides. Preferably, the cross beam connection component 2 is detachably connected to the vehicle body 12 to improve the convenience of overall disassembly and assembly of the frame body.

[0062] For the convenience of vehicle use, as Figure 2 and Figure 4As shown, as a preferred embodiment, the gas cylinder mounting parts 3 on each cross beam 1 are multiple, and the multiple gas cylinder mounting parts 3 are arranged at intervals along the first direction. The multiple gas cylinder mounting parts 3 on each cross beam 1 are all connected to the cross beam 1 through the first screwing structure 4. In this structure, the gas cylinder mounting parts 3 on each cross beam 1 are all set to be multiple, which is convenient for installing multiple gas cylinders 5, making the vehicle application more convenient.

[0063] In this embodiment, there are three gas cylinders 5, and the three gas cylinders 5 are arranged at intervals along the first direction. Both ends of each gas cylinder 5 are installed on the cross beam 1 through the gas cylinder mounting parts 3 at corresponding positions. Preferably, each gas cylinder mounting part 3 is connected to the cross beam 1 through the first screwing structure 4, so that the gas cylinder mounting part 3 is convenient for disassembly and assembly, and thus it is convenient to disassemble and assemble the gas cylinder 5.

[0064] It should be noted that the number of gas cylinders 5 can be other numbers besides three. At this time, only the length of the cross beam 1 and the number of groups of gas cylinders 5 need to be changed. When adapting to different vehicle models, the modification cost is relatively low.

[0065] As Figure 5 shown, as a preferred embodiment, each gas cylinder mounting part 3 includes a first fixing part 301 and a second fixing part 302. The first fixing part 301 is connected to the cross beam 1 through the first screwing structure 4.

[0066] Specifically, the first screwing structure 4 mainly includes a first bolt passing through the gas cylinder mounting part 3 and the cross beam 1, and a first nut screwed to the first bolt. In this embodiment, the first fixing part 301 is detachably installed on the cross beam 1 through the first screwing structure 4, and the second fixing part 302 and the first fixing part 301 are detachably connected, and an installation space is formed between the two.

[0067] As Figure 6 shown, both ends of the gas cylinder 5 are provided with extension parts 501 extending axially outward along itself. The radial dimension of the extension part 501 is smaller than the radial dimension of the gas cylinder 5. The extension parts 501 at both ends of the gas cylinder 5 are respectively inserted into the corresponding installation spaces, so that both ends of the gas cylinder 5 are installed on the cross beam 1 through the gas cylinder mounting parts 3 at corresponding positions.

[0068] Specifically, the second fixing part 302 and the first fixing part 301 are connected through a second screwing structure 13. The second fixing part 302 and the first fixing part 301 are both in a U-shape, having good structural strength and being convenient for connection. The second screwing structure 13 includes a second bolt passing through the second fixing part 302 and screwed to the first fixing part 301. Existing standard parts can be used, and the cost is relatively low.

[0069] In the above structure, each gas cylinder installation part 3 includes a first fixing member and a second fixing member 302 that are detachably connected, which can further improve the convenience of installing and disassembling a single gas cylinder 5. Extension parts 501 are provided at both ends of the gas cylinder 5, and the extension parts 501 are inserted into the installation space surrounded by the first fixing member 301 and the second fixing member 302, which has the effects of reducing weight and cost compared with the existing installation straps for gas cylinders.

[0070] It should be noted that in this embodiment, the gas cylinder installation part 3 including the detachably connected first fixing member 301 and second fixing member 302 is taken as an example for illustration. In addition, for example, a second bolt can also pass through the cross beam 1, and the second bolt is matched with a second nut to make the connection between the first fixing member 301 and the second fixing member 302 reliable and can be firmly fixed on the cross beam 1.

[0071] Still referring to Figure 4 and Figure 5 As shown, as a preferred embodiment, each connecting beam 202 includes a cross beam connecting section 2021, a longitudinal beam connecting section 2022, and a vehicle body connecting section 2023 that are connected in sequence. The connecting beams 202 at both ends are detachably connected to the cross beam 1 through the cross beam connecting sections 2021 respectively, and each longitudinal beam 201 is connected to the longitudinal beam connecting sections 2022 at both ends respectively. A vehicle body connecting part is provided on the vehicle body connecting section 2023.

[0072] In this embodiment, the connecting beam 202 includes a cross beam connecting section 2021, a longitudinal beam connecting section 2022, and a vehicle body connecting section 2023, which is convenient for connecting with the cross beam 1 and the vehicle body 12, and is also convenient for connecting with the longitudinal beam 201. The cross beam connecting section 2021 is detachably connected to the cross beam 1, so that the cross beam 1 can be detached from the cross beam connecting assembly 2, further improving the convenience of disassembly and assembly.

[0073] In addition, the vehicle body connecting part is specifically a connecting hole provided on the vehicle body connecting section 2023. The vehicle body connecting section 2023 can be connected to the vehicle body through a connecting member such as a bolt passing through the connecting hole, forming a structure in which the vehicle body connecting section 2023 is detachably connected to the vehicle body 12, which is convenient for disassembly and assembly, and the connection stability and reliability are also relatively high.

[0074] It should be noted that in the above structure, connecting the longitudinal beam 201 between the two longitudinal beam connecting sections 2022 is convenient for overall layout, and the connection reliability and stability are relatively high, which is beneficial to ensuring the overall structural strength and is also convenient for layout on the vehicle. It should be understood that it is also possible to connect the longitudinal beam 201 between the two cross beam connecting sections 2021, or to connect the longitudinal beam 201 between the two vehicle body connecting sections 2023.

[0075] For the convenience of disassembly and assembly, as a preferred embodiment, each connecting beam 202 has an overlapping portion 20211 overlapping with the connected cross beam 1, and the overlapping portion 20211 is connected to the cross beam 1 through a first screwing structure 4 that fixes at least one gas cylinder mounting portion 3. Still referring to Figure 2 and Figure 4 As shown, the overlapping portion 20211 is specifically provided on the cross beam connecting section 2021. A through hole is provided on the overlapping portion 20211 for two first bolts of the pneumatic mounting portion near the end of the cross beam 1 to pass through, so that a stable and reliable connection can be achieved between the cross beam connecting section 2021 and the cross beam 1.

[0076] It should be noted that in this embodiment, the overlapping portion 20211 provided on the cross beam connecting section 2021 has the effect of improving the connection reliability of the connection part between the cross beam 1 and the connecting beam 202 and the overall structural strength. The overlapping portion 20211 is also connected to the cross beam 1 by the first screwing structure 4, which can also play the role of reducing weight and cost.

[0077] In terms of specific structure, for the convenience of layout on the vehicle body 12, as a preferred embodiment, each cross beam connecting section 2021 and each vehicle body connecting section 2023 extend along the first direction, and the longitudinal beam connecting section 2022 extends along the third direction, and the third direction is different from both the first direction and the second direction. Here, the extension directions of the cross beam connecting section 2021, the longitudinal beam connecting section 2022 and the vehicle body connecting section 2023 are defined to facilitate the overall layout.

[0078] It should still be noted that in a preferred embodiment, flanges are provided on both sides of the connecting beam 202, so that the cross section of the connecting beam 202 is in a "C" shape. In this way, the connecting beam 202 itself has relatively high structural strength and can better ensure the structural strength and application reliability of the frame body.

[0079] For better protection of the gas cylinder 5, as a preferred embodiment, the gas cylinder mounting structure of this embodiment further includes a protection plate 6. The protection plate 6 is blocked on one side of the gas cylinder 5 and is connected to the cross beam 1 through the first screwing structure 4 on each cross beam 1. The protection plate 6 provided here can effectively protect the gas cylinder 5. It should be noted that Figure 1 The structure shown is the structure seen roughly from bottom to top. When the gas cylinder mounting structure is arranged on the vehicle, the protection plate 6 is blocked under the gas cylinder 5, that is, the protection plate 6 is arranged closer to the ground relative to the gas cylinder 5, so as to better prevent debris on the road surface from hitting the gas cylinder 5.

[0080] Specifically, as Figure 1As shown, along the second direction, through holes are provided on both sides of the protection plate 6, and the through holes on both sides correspond one by one to the first bolts on the corresponding side of the cross beam 1, so that the protection plate 6 can be connected to the cross beam 1 by passing the first bolts through the respective through holes. The protection plate 6 is convenient to disassemble and install, and with the addition of the protection plate 6, its installation cost is relatively low, and the overall structural strength and impact resistance of the frame body can be improved.

[0081] For the convenience of overall layout, in a preferred embodiment, the protection plate 6 is in a "ji" shape, which not only makes the protection plate 6 have high structural strength, but also makes it convenient for the protection plate 6 to be connected to the cross beam 1 by using the first screwing structure 4. Here, the protection plate 6 and the gas cylinder installation part 3 share the first screwing structure 4, which is also beneficial to reducing weight and production costs, and can better protect the gas cylinder 5.

[0082] To meet the lightweight requirements of the vehicle, as Figure 1 shown, in a preferred embodiment, the protection plate 6 is provided with weight reduction holes 601, which have a good weight reduction effect and can better meet the lightweight requirements of the vehicle. Preferably, the weight reduction holes 601 are arranged on the protection plate 6 at positions avoiding the gas cylinder 5, which can not only better drain water and prevent rust, but also reduce weight and can better protect the gas cylinder 5.

[0083] It should be noted that the number of the weight reduction holes 601 is not limited to Figure 1 the six shown, and the shape of the weight reduction holes 601 is not limited to the long strip extending along the second direction. The number and shape of the weight reduction holes 601 are set according to actual needs, as long as the protection effect on the gas cylinder 5 is not affected.

[0084] To facilitate the installation and disassembly of the frame body on the vehicle body 12, as Figure 2 and Figure 3 shown, as a preferred embodiment, a pressure reducing valve 7 and a hydrogen filling port 8 are provided on one of the longitudinal beams 201. The inlet of the pressure reducing valve 7 is communicated with the gas cylinder 5, a quick connector 702 is provided at the outlet of the pressure reducing valve 7, and the hydrogen filling port 8 is communicated with the gas cylinder 5.

[0085] In this embodiment, there are multiple gas cylinders 5. One interface of the pressure reducing valve 7 is connected to each gas cylinder 5. For example, an existing gas distributor can be used to connect to the multiple gas cylinders 5 respectively. The hydrogen filling port 8 can be directly connected to the gas cylinder 5, or can be connected to the multiple gas cylinders 5 respectively by means of an existing gas distributor, so that the gas cylinders 5 in this gas cylinder installation structure can be filled with gas at a hydrogen filling station without replacing the gas cylinders 5.

[0086] In this embodiment, a quick connector 702 is provided on the pressure reducing valve 7. The quick connector 702 is used to communicate with the hydrogen discharge port 14 on the hydrogen using pipeline. A quick connector 702 fitting is provided at one end of the hydrogen using pipeline close to the pressure reducing valve 7. The quick connector 702 and the quick connector 702 fitting are plugged and connected. The specific structures of both can refer to the existing quick plug structure with sealing function.

[0087] With such a setting, when the gas cylinder installation structure and the installed gas cylinder 5 and the protection plate 6 are assembled and disassembled on the vehicle body 12 as a whole, only the part provided with the quick connector 702 needs to be disconnected in the hydrogen supply pipeline. When it is necessary to replace the gas cylinder 5, the gas cylinder installation structure is assembled and disassembled as a whole, and the quick connector 702 can be plugged and unplugged at one position.

[0088] After the gas cylinder 5 is replaced, hydrogen replacement can be carried out through the hydrogen discharge port 14. Only the airtightness of the plug connector 702 at this position needs to be detected. The disassembly and assembly are convenient, and the use is also convenient, which can better ensure the purity and quality of hydrogen. Since other positions are not disassembled, there is no need to detect other positions, reducing the time for airtightness detection.

[0089] Through the above description, the gas cylinder installation structure of this embodiment can supplement hydrogen by the way of hydrogen addition at a hydrogen refueling station, or replace all gas cylinders 5 by the way of replacing the gas cylinder 5 at a gas storage station, and the use is very convenient.

[0090] In a preferred embodiment, the above pressure reducing valve 7 is a pressure reducing valve 7 integrated with a four-way joint 701. Specifically, still referring to Figure 2 and Figure 3 As shown, the first connection port 7011, the second connection port 7012 and the third interface 7013 of the four-way joint 701 are respectively used to communicate with the gas inlet and outlet of the gas cylinder 5. The fourth interface 7014 of the four-way joint 701 is connected to the hydrogen addition port 8, so that the hydrogen addition port 8 can be respectively connected to each gas cylinder 5, which can save the number of pipelines arranged. A quick connector 702 is provided at the outlet of the pressure reducing valve 7, and one interface of the four-way joint 701 is connected to one interface of the pressure reducing valve 7 body.

[0091] It should be noted that in addition to being connected to each gas cylinder 5 through the pressure reducing valve 7 integrated with the four-way joint 701, pipelines can also be respectively arranged between the hydrogen addition port 8 and each gas cylinder 5 to make the hydrogen addition port 8 be respectively connected to each gas cylinder 5.

[0092] In the above structure, by setting the pressure reducing valve 7 integrated with the four-way joint 701, when applied to a vehicle, the existing gas distributor can be omitted, the number of hydrogen supply pipelines can be reduced, which is beneficial to reducing costs. Moreover, the four-way joint 701 is also connected to the hydrogen addition port 8, which is convenient for supplementing hydrogen to multiple gas cylinders 5 through a hydrogen refueling station. When the whole gas cylinder installation structure is disassembled, only the quick connector 702 needs to be disconnected. After replacing the gas cylinder 5, only the airtightness of the quick connector 702 part needs to be detected, and the use is convenient.

[0093] To facilitate the installation and removal of the hydrogen filling port 8, as a preferred embodiment, the pressure reducing valve 7 is detachably connected to the longitudinal beam 201 through the first bracket 9, which is beneficial to improving the convenience of installing and removing the pressure reducing valve 7. The first bracket 9 can be installed on the longitudinal beam 201 through a screwing structure, for example, and the disassembly and assembly are relatively convenient. As for the shape and structure of the first bracket 9, no specific limitation is made in this embodiment, as long as the pressure reducing valve 7 can be fixed stably and reliably.

[0094] To facilitate the installation and removal of the pressure reducing valve 7, as a preferred embodiment, the hydrogen filling port 8 is detachably connected to the longitudinal beam 201 through the second bracket 10, which is beneficial to improving the convenience of installing and removing the hydrogen filling port 8. For example, the second bracket 10 is also installed on the longitudinal beam 201 through a screwing structure, and the disassembly and assembly are relatively convenient. In this embodiment, the shape and structure of the second bracket 10 are not specifically limited, as long as the hydrogen filling port 8 can be fixed stably and reliably.

[0095] In the gas cylinder installation structure of this embodiment, the pipelines between the hydrogen filling port 8 and the gas cylinder 5 and between the pressure reducing valve 7 and the gas cylinder 5 are high-pressure pipelines. Since the high-pressure pipe inspection requires pressurization to 87.5 Mpa, pressure detection equipment and time are needed, which is very complex and time-consuming. However, the pressure reducing valve 7 and the hydrogen filling port 8 are integrated on the frame main body of this embodiment, which can avoid the airtightness detection of the high-pressure pipeline and is beneficial to saving time and cost.

[0096] In addition, the hydrogen filling port 8 and the pressure reducing valve 7 are arranged on one side of the gas cylinder 5, which can make more effective use of space. When the cruising range needs to be increased by increasing the number of gas cylinders 5, it can ensure the universality of the structure here and reduce the vehicle cost.

[0097] Finally, it should be noted that, as Figure 6 shown, two protective covers 502 are arranged at intervals in the axial direction of each gas cylinder 5. The radial dimension of the gas cylinder main body of the gas cylinder 5 is relatively large, and the two protective covers 502 are sleeved on both ends of the gas cylinder main body. The shapes of the two protective covers 502 conform to the shape of the end of the gas cylinder main body, which can better protect the gas cylinder 5.

[0098] In addition, as Figure 4 and Figure 5 shown, a hydrogen sensor 11 is arranged on the vehicle body 12 near the pressure reducing valve 7. Since there are many gas path interfaces at the position of the pressure reducing valve 7, the possibility of gas leakage is relatively large. Therefore, the hydrogen sensor 11 is arranged close to the pressure reducing valve 7, which is convenient for timely detection in case of gas leakage. The hydrogen sensor 11 is specifically connected to the controller on the vehicle, and the gas leakage information can be transmitted to the controller in time, which is convenient for the controller to make corresponding countermeasures in time.

[0099] The gas cylinder installation structure of this embodiment has a simple overall structure, is relatively light in weight, is convenient for disassembling and installing the gas cylinder 5, and is also convenient for disassembling and installing on the vehicle. It is convenient to replace the gas cylinder 5 at the gas storage station, which can greatly improve the application convenience. When the above gas cylinder installation structure is installed on different vehicle models, only the size of the cross beam 1 needs to be adjusted, the structure of the cross beam connection assembly 2 remains unchanged, the modification is less, the cost is lower, and it is easy to apply.

[0101] This embodiment relates to a vehicle, on which there is a gas cylinder installation structure as in Embodiment 1.

[0102] For the vehicle of this embodiment, by applying the gas cylinder installation structure of Embodiment 1, it is convenient to disassemble and install the gas cylinder 5, and the gas cylinder installation structure is also convenient for disassembling and installing on the vehicle, with high application convenience. When the gas cylinder installation structure of Embodiment 1 is installed on different vehicle models, only the size of the cross beam 1 needs to be adjusted, the modification is less, the cost is lower, and it is easy to apply.

[0103] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
