[0038] The following will describe in detail the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0039] In the present disclosure, unless otherwise stated, "inner and outer" refer to the inside and outside of the contour of the corresponding component; in addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another element.

[0040] According to the first aspect of the present disclosure, as Figure 1 , Figure 3 and Figure 4 shown, a gas cylinder saddle 100 is provided. The gas cylinder saddle 100 may include a mounting base 1 and a strap assembly 2. At least two connecting shafts 3 are rotatably connected to the mounting base 1. The strap assembly 2 may include a strap body 21 and a connecting member 22. Both ends of the strap body 21 are respectively connected with a connecting member 22. Each connecting member 22 is respectively connected to the connecting shaft 3, so that the strap assembly 2 and the mounting base 1 jointly enclose a mounting space 4 for the gas cylinder 2000 to pass through along the first direction. The rotation axis of the connecting shaft 3 is parallel to the first direction. As Figure 1 the dotted line a in Figure 1In the Y direction, the Y direction can be the extending direction when the gas cylinder 2000 is connected to the gas cylinder saddle 100. For example, when the gas cylinder 2000 is placed extending in the front-rear direction of the vehicle, the Y direction can be the front-rear direction of the vehicle. Or, when the gas cylinder 2000 is placed extending in the left-right direction of the vehicle, the Y direction can be the left-right direction of the vehicle. Or, when the gas cylinder 2000 is placed extending in the height direction of the vehicle, the Y direction can be the height direction of the vehicle. As Figure 4 shown, in addition, the connecting members 22 respectively connected to both ends of the strap body 21 can be configured as threaded connecting rods. Correspondingly, a connecting hole 33 for the connecting rod to pass through can be formed on the connecting shaft 3, and the connecting rod can be locked and fixed by a nut after passing through the connecting hole 33. Further, a gasket can be additionally provided between the nut and the connecting shaft 3. The gasket can reduce the wear between the connecting member 22 and the connecting shaft 3 and improve the service life of the connecting member 22 and the connecting shaft 3. In addition. The gasket can also increase the contact area between the connecting member 22 and the connecting shaft 3. Of course, the connecting member 22 can also be configured as other connecting columns, connecting protrusions, etc., which are not limited herein. Correspondingly, the connection method between the connecting member 22 and the connecting shaft 3 is also not limited herein, and other suitable methods such as clamping and welding can be adopted, and those skilled in the art can design and adjust according to the actual situation.

[0041] Through the above technical solution, when the gas cylinder 2000 is assembled with the gas cylinder saddle 100, the gas cylinder 2000 can be passed through the installation space 4 formed by the common enclosure of the strap assembly 2 and the installation base 1 to achieve the purpose of fixed installation of the gas cylinder 2000. When the gas cylinder 2000 moves or has a moving tendency deviating from the first direction, the gas cylinder 2000 can drive the connecting shaft 3 to rotate through the strap body 21 and the connecting member 22. Thus, the traction and pulling force of the strap body 21 from the gas cylinder 2000 are compensated by the rotation of the connecting shaft 3, and the traction effect of the strap body 21 on the installation base 1 is also effectively reduced, avoiding the problem in the related art that the strap is fixedly connected to the installation base, resulting in too concentrated stress of the strap and causing the installation base to be welded open or the strap to be separated from the installation base, and improving the use reliability of the gas cylinder saddle 100.

[0042] In some embodiments, such as Figure 1 and Figure 2As shown, the mounting base 1 may include two relatively arranged supporting portions 11 and a connecting portion 12 disposed between the two supporting portions 11. The connecting shaft 3 penetrates through the two supporting portions 11. The connection position of the connecting member 22 and the connecting shaft 3 is located on one side of one of the supporting portions 11 facing away from the other supporting portion 11. In this way, arranging the connecting shaft 3 to penetrate through the two supporting portions 11 can strengthen the connection strength between the connecting shaft 3 and the mounting base 1. Further, the above arrangement can make the two ends of the strap body 21 located on the same side of the same supporting portion 11, so that a relatively reliable and stable compensation can be formed for the traction and pulling force of the strap body 21 from the gas cylinder 2000 through the rotation of the connecting shaft 3, improving the use reliability of the gas cylinder saddle 100.

[0043] In some embodiments, as Figure 2 shown, the mounting base 1 may further include a reinforcing portion 13. The reinforcing portion 13 is located on the connecting portion 12. Providing the reinforcing portion 13 on the connecting portion 12 connecting the two supporting portions 11 can effectively improve the structural strength of the mounting base 1, for example, can improve the anti-deformation ability of the mounting base 1. For example, the reinforcing portion 13 may be configured as a reinforcing protrusion or a reinforcing rib, etc., and the present disclosure is not limited thereto.

[0044] The reinforcing portion 13, the supporting portion 11 and the connecting portion 12 may be integrally formed. For example, they may be integrally stamped, and such a forming method has low cost and high structural strength, avoiding the need to splice various materials by welding in the related art, that is, avoiding the generation of weld seams. Thus, during the subsequent operation of the vehicle, the problem that the mounting base 1 is welded open when the strap body 21 exerts a traction force on the mounting base 1 is also avoided.

[0045] In some embodiments, as Figure 2 shown, the gas cylinder saddle 100 may further include a plurality of reinforcing members 5. The reinforcing members 5 are connected between the two supporting portions 11. The plurality of reinforcing members 5 are arranged side by side and at intervals. For example, the reinforcing member 5 may be formed by bending a sheet metal part. It should be noted here that when the gas cylinder 2000 is placed on the mounting base 1, the two supporting portions 11 on the mounting base 1 are the parts where the force is more concentrated. Arranging the reinforcing members 5 between the two supporting portions 11 can effectively improve the structural strength of the mounting base 1. Preferably, the reinforcing member 5 may be connected to the supporting portion 11 by riveting. Of course, it can be understood that the reinforcing member 5 may also be connected by other connection methods such as bolt connection and welding, which are not limited herein, and those skilled in the art can choose according to the actual situation.

[0046] In some embodiments, as Figure 1 and Figure 2As shown, the mounting base 1 extends in the second direction. A plurality of arc-shaped mounting portions 14 are formed on the mounting base 1 and are arranged at intervals in the second direction. The number of the strap assemblies 2 is the same as that of the arc-shaped mounting portions 14 and they correspond one by one. The arc-shaped mounting portion 14 and the corresponding strap assembly 2 together enclose a mounting space 4. Among them, the second direction can be perpendicular to the first direction, and reference can be made to Figure 1 the X direction shown in

[0047] The arc-shaped mounting portion 14 can include two arc-shaped plates respectively arranged on the two support portions 11, so as to fit and support the outer wall surface of the gas cylinder 2000 through the two arc-shaped plates, so as to increase the contact area with the gas cylinder 2000, reduce stress concentration, and improve the reliability of the gas cylinder saddle 100. Among them, the two arc-shaped plates can be processed synchronously when the mounting base 1 is integrally stamped.

[0048] In some embodiments, as Figure 2 shown, a weight-reducing hole 54 can also be provided on the reinforcing member 5. The setting of the weight-reducing hole 54 can reduce the weight of the mounting base 1 without affecting the strengthening effect, achieving the purpose of lightweight design.

[0049] In some embodiments, as Figure 2 shown, the reinforcing member 5 can include a first plate body 51 and a second plate body 52 which are oppositely arranged and a third plate body 53 connected between the first plate body 51 and the second plate body 52. The first plate body 51 is connected to one of the two support portions 11. The second plate body 52 is connected to the other of the two support portions 11. In this structural form of the reinforcing member 5, on the one hand, the forming method is relatively simple and can be obtained by bending a sheet metal part. On the other hand, the first plate body 51 and the second plate body 52 can have a large connection area with the two support portions 11, improving the reliability of use of the reinforcing member 5. Among them, the weight-reducing hole 54 can be opened on the third plate body.

[0050] In some embodiments, as Figure 1As shown, the connecting shaft 3 can be configured as a pin shaft 31. A pin hole 32 is formed in the pin shaft 31. A split pin 6 is inserted into the pin hole 32. The split pin 6 is located between the connecting member 22 and the supporting portion 11 adjacent to the connecting member 22, so as to jointly limit the position of the pin shaft 31 in the first direction with the head of the pin shaft 31. The present disclosure adopts the pin shaft 31 as the connecting shaft 3 mainly by taking advantage of its advantages such as reliable work and convenient disassembly. Further, the adoption of the split pin 6 can further improve the working reliability of the connecting shaft 3.

[0051] According to the second aspect of the present disclosure, as Figure 5 shown, a gas cylinder frame 1000 is provided. The gas cylinder frame 1000 may include a frame body 200 and the above-mentioned gas cylinder saddle 100. The mounting base 1 is detachably connected to the frame body 200. The gas cylinder frame 1000 equipped with the gas cylinder saddle 100 also has relatively reliable structural strength. Regarding the structural form of the gas cylinder frame 1000, the present disclosure does not make specific limitations here, and those skilled in the art can design and adjust according to actual situations. Among them, the mounting base 1 can be connected to the frame body 200 in any suitable manner. For example, two supporting portions 11 can be clamped on the frame body 200 so that the mounting base 1 is fixed relative to the frame body 200. Specifically, bolts are sequentially passed through one of the two supporting portions 11, the frame body 200, and the other of the two supporting portions 11, and locked with nuts to achieve the connection between the mounting base 1 and the frame body 200. Of course, it can be understood that the mounting base 1 can also be connected to the frame body 200 in other forms such as riveting and welding, which are not limited here.

[0052] According to the third aspect of the present disclosure, as Figure 6 shown, a hydrogen storage system 3000 is provided. The hydrogen storage system 3000 may include a gas cylinder 2000 and the above-mentioned gas cylinder frame 1000. The gas cylinder 2000 is installed on the gas cylinder frame 1000. The hydrogen storage system 3000 formed by installing the gas cylinder 2000 through the frame body 200 can also have relatively high use safety.

[0053] According to the fourth aspect of the present disclosure, a vehicle is provided. The vehicle may include the above-mentioned hydrogen storage system 3000. The vehicle equipped with the hydrogen storage system 3000 can also have relatively good driving safety.

[0054] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
