The first sub-frame 31 is a rod member, and the second sub-frame 32 is a plate member. The electrical components and / or pipelines of the hydrogen bottle are distributed in the first sub-frame 31.

[0035] The frame 94 includes a frame 3, and the number of the frame 3 can be multiple, and the multiple frames 3 are arranged along the first direction (ie Figure 1 The number of the frames 3 may be, but is not limited to, five, six, seven, etc. As some embodiments of the present application, the number of the frames 3 is six.

[0036] The frame 94 further includes a longitudinal beam 2, which is arranged along a first direction (i.e. Figure 1 The longitudinal beam 2 is arranged to extend in the Z direction as shown, and the longitudinal beam 2 can connect multiple frames 3, wherein the connection method between the longitudinal beam 2 and the multiple frames 3 can be but not limited to welding, screwing, etc. As some embodiments of the present application, the longitudinal beam 2 is connected to the multiple frames 3 by welding.

As some embodiments of the present application, along the second direction (i.e. Figure 1 The three longitudinal beams 2 are arranged at intervals along the third direction (i.e. Figure 1 Along the first direction (i.e. Figure 1A placement space 93 is defined between each two adjacent frames 3, and the placement space 93 can be used to place a hydrogen bottle.

[0037] The frame 3 includes a first subframe 31 and a second subframe 32, which are arranged along the length of the hydrogen bottle from the bottle head to the bottle tail, that is, along the second direction (i.e. Figure 1 The frame 3 structure corresponding to the bottle head of the hydrogen bottle is a first sub-frame 31, and the frame structure corresponding to the bottle tail of the hydrogen bottle is a second sub-frame 32, wherein the first sub-frame 31 is made of rods, and the second sub-frame 32 is made of plates.

[0038] Specifically, the frame 3 includes a plate and a rod, the second sub-frame 32 is made of a plate, and the first sub-frame 31 is made of a rod.

Therefore, the first subframe 31 can be made of rods, which can ensure the reliability of the hydrogen bottle fixing bracket 100. Figure 2 The weight of the second sub-frame 32 (as shown on the right side) is relatively small, so the second sub-frame 32 can be made of plate to achieve a lightweight design of the hydrogen bottle fixing bracket 100.

[0051] By arranging at least a portion of the pipeline fixing frame 6 on the first sub-frame 31, the pipelines can be centrally arranged on the first sub-frame 31, so that the space of the hydrogen bottle fixing bracket 100 can be reasonably utilized, and the space utilization rate of the hydrogen bottle fixing bracket 100 is increased. Moreover, by arranging at least a portion of the pipeline fixing frame 6 on the first sub-frame 31, at least a portion of the pipeline can be observed at close range by opening the door body 42, thereby facilitating the repair and maintenance of the pipelines of the hydrogen bottle fixing bracket 100.

[0052] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the hydrogen bottle fixing bracket 100 also includes: a plurality of connecting parts 90, the connecting parts 90 include: a connecting bottom beam 91 and a support beam 92, the connecting bottom beam 91 is arranged on the frame body 94 and is suitable for connecting to the body of the vehicle, and the support beam 92 is connected between the connecting bottom beam 91 and the frame 3.

[0055] As some embodiments of the present application, Figure 1 As shown, the frame body 94 includes six frames 3, and the six frames 3 are arranged along a first direction (i.e. Figure 1 The hydrogen bottle fixing bracket 100 includes two connecting members 90, and the connecting bottom beams 91 of the two connecting members 90 are both arranged below the lowest frame 3, and the two connecting members 90 are arranged along the second direction (i.e. Figure 1 The two connecting members 90 are arranged at intervals in the Y direction as shown, and the support beams 92 of the two connecting members 90 are both connected to the middle frame 3 (for example, the support beams 92 of the two connecting members 90 are both connected to the fourth frame 3 from the bottom to the top).

[0056] By connecting the support beam 92 between the connecting bottom beam 91 and the frame 3, when the hydrogen bottle fixing bracket 100 needs to be adapted to different vehicle models, the positions of the support beam 92 and the connecting bottom beam 91 can be changed along the extension direction of the frame 3 (for example, the support beam 92 and the connecting bottom beam 91 are translated as a whole along the extension direction of the frame 3), so that the hydrogen bottle fixing bracket 100 can be adapted to different vehicle models, and the versatility of the hydrogen bottle fixing bracket 100 can be improved, which is beneficial to shorten the design cycle of the vehicle and reduce the production cost of the vehicle.

[0058] The plurality of longitudinal beams 2 include a first sub-longitudinal beam 21 and a second sub-longitudinal beam 22.

[0059] The number of the first sub-longitudinal beams 21 may be multiple, and the number of the first sub-longitudinal beams 21 may be, but is not limited to, four, six, eight, etc. As some embodiments of the present application, the multiple first sub-longitudinal beams 21 are arranged along the second direction (i.e. Figure 1 The Y direction shown in the figure) is arranged in a row, and the third direction (i.e. Figure 1 In the X direction as shown in the figure, multiple rows of first sub-longitudinal beams 21 are arranged at intervals. As some embodiments of the present application, along the second direction (i.e. Figure 1 The two first longitudinal beams 21 are arranged in a row at intervals, and along the third direction (ie Figure 1 Two rows of first sub-longitudinal beams 21 (in the X direction as shown) are arranged at intervals.

[0060] The first sub-longitudinal beam 21 is a rod-shaped member. It is understandable that the first sub-frame 31 needs to bear the bottle head of the hydrogen bottle, which is heavy. Therefore, by making the first sub-longitudinal beam 21 connected to the first sub-frame 31 a rod-shaped member, the reliability of the hydrogen bottle fixing bracket 100 can be ensured.

[0062] As some embodiments of the present application, along the third direction (i.e. Figure 1 In the X direction shown in the figure, two second sub-longitudinal beams 22 are arranged at intervals.

[0063] The second sub-longitudinal beam 22 is a plate member.

[0064] Such an arrangement can make the structure of the hydrogen bottle fixing bracket 100 reasonable, and by making the second sub-longitudinal beam 22 a plate member, a lightweight design can be performed on the basis of ensuring the reliability of the use of the hydrogen bottle fixing bracket 100.
