DETAILED DESCRIPTION

[0032] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0033] In this disclosure, unless otherwise stated, directional words such as "upper, lower, top, and bottom" refer to the upper, lower, top, and bottom in the direction of gravity in actual use, wherein the directions "upper and lower" correspond to Figure 1 The upper and lower positions in the drawings. In addition, "inside" and "outside" refer to the "inside" and "outside" relative to the outline of the corresponding component itself. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another and do not have sequentiality and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure marks in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0034] The present disclosure provides a vehicle, referring to Figure 1 and Figure 2 As shown in the figure, the vehicle includes a frame 1; a subbeam 2, including a first subbeam 21 and a second subbeam 22 that are detachably connected, the first subbeam 21 and the second subbeam 22 are arranged parallel to the frame 1 and are arranged in sequence along the horizontal longitudinal direction; a frame body 3, the frame body 3 is arranged above the frame 1 and has a first installation space 31 and a second installation space 32 that are independent of each other formed therein, the frame body 3 is detachably connected to the frame 1 through the first subbeam 21; a hydrogen bottle bracket 4, arranged in the first installation space 31 and fixedly connected to the frame body 3; and an electrical component bracket 5, arranged in the second installation space 32 and detachably connected to the frame body 3 and the frame 1 respectively through the second subbeam 22.

[0035] Through the above technical solution, in the vehicle provided by the present invention, by arranging the frame body 3 above the vehicle frame 1 and forming a first installation space 31 and a second installation space 32 independent of each other inside the frame body 3, the hydrogen bottle holder 4 is arranged in the first installation space 31, and the electrical component holder 5 is arranged in the second installation space 32, so that the hydrogen bottle 9 and the electrical component can be installed in the first installation space 31 and the second installation space 32 through the corresponding hydrogen bottle holder 4 and the electrical component holder 5 respectively, so as to realize the integration of the hydrogen bottle 9 and the electrical component at the installation position.

[0036] Among them, since the sub-beam 2 includes a first sub-beam 21 and a second sub-beam 22 that are detachably connected, and the frame body 3 is detachably connected to the frame 1 through the first sub-beam 21, and the electrical component bracket 5 is detachably connected to the frame body 3 and the frame 1 respectively through the second sub-beam 22, when it is necessary to perform regular maintenance or overhaul on the hydrogen storage system consisting of the hydrogen bottle 9 in the vehicle, the frame body 3 and the hydrogen bottle bracket 4 and the hydrogen bottle 9 installed on the frame body 3 can be removed from the frame 1 through the first sub-beam 21. Among them, since the first sub-beam 21 is detachably connected to the second sub-beam 22, and the second sub-beam 22 is also detachably connected to the frame body 3, during the above-mentioned removal process, it is possible to remove the frame body 3 from the frame 1 while still keeping the electrical component bracket 5 on the frame 1 through the second sub-beam 22.

[0037] Furthermore, since the electrical component bracket 5 is equipped with various electrical components for ensuring smooth and safe operation of the vehicle, including electrical components connected to the power battery, and the role of the power battery in a fuel cell vehicle is to store excess electricity generated by the fuel cell and electrical energy recovered during vehicle driving, so as to assist the fuel cell in providing power, therefore, through the above arrangement, during the maintenance or overhaul of the hydrogen storage system, even if the hydrogen storage system is removed from the vehicle frame 1, since the electrical component bracket 5 is still mounted on the vehicle frame 1, and various electrical components are mounted on the electrical component bracket 5, the vehicle can also be electrically connected to the power battery through these electrical components, and the power battery is used to drive the motor to work, thereby completing the short-distance travel of the vehicle and realizing the adjustment of the vehicle to its current position without the need for additional auxiliary tools, which greatly facilitates the use of the vehicle during the maintenance or overhaul of the hydrogen storage system.

[0038] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 As shown in the figure, the first installation space 31 may include a first sub-installation space 311 and multiple second sub-installation spaces 312, and the second installation space 32 includes a first sub-installation space 311 and a second installation space 32 arranged in sequence along the horizontal longitudinal direction, and multiple second sub-installation spaces 312 are arranged above the first sub-installation space 311 and the second installation space 32 respectively in the vertical direction, wherein the first sub-installation space 311, the second sub-installation space 312 and the second installation space 32 have the same size.

[0039] Through the above technical solution, the interior of the frame body 3 can be divided into multiple installation spaces of equal size while rationally utilizing the vehicle space. This not only facilitates the installation of the hydrogen bottle 9 and electrical components, but also facilitates the fabrication of the frame body 3. Furthermore, since the installation space for the hydrogen bottle 9 is typically large, and the first sub-installation space 311 is used to install the hydrogen bottle 9, and the first sub-installation space 311 and the second installation space 32 are of equal size and arranged in a horizontal and longitudinal sequence, the electrical component installation space (i.e., the second installation space 32) arranged alongside the hydrogen bottle 9 installation space (i.e., the first sub-installation space 311) is also larger and more spacious. The two sub-installation spaces are identical in length, width, and height. Therefore, when workers use the second installation space 32 to install, remove, and repair electrical components, they have ample space in all directions, including length, width, and height, making it easier to maneuver. In particular, the increased height allows workers to maintain a more comfortable standing posture during work, avoiding prolonged bending or even crouching, thus greatly facilitating operations.

[0040] Among them, since the power battery (not shown in the figure) is arranged at the rear of the frame body 3, that is, the power battery is arranged on the side of the frame body 3 away from the cab, therefore, in order to facilitate wiring while ensuring the connection between the power battery and the electrical components, the second installation space 32 can be set on the side of the first sub-installation space 311 close to the power battery, that is, in the frame body 3, the second installation space 32 is arranged on the side away from the cab, and the first sub-installation space 311 is arranged on the side where the cab is located.

[0041] In addition, according to the height requirement of the vehicle, the frame body 3 may include not only four second sub-installation spaces 312 (such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 as well as Figure 9 As shown in the figure), it can also include six second sub-installation spaces 312 (not shown in the figure). In this case, the other two second sub-installation spaces 312 are respectively arranged above the two second sub-installation spaces 312 on the third layer. When the vehicle type is a heavy truck, it is usually necessary to be equipped with at least four hydrogen cylinders 9, and the arrangement of these hydrogen cylinders 9 in the first sub-installation space 311 and each second sub-installation space 312 needs to lower the center of gravity and ensure reliable installation.

[0042] Exemplarily, when there are four hydrogen bottles 9 and a frame body 3 with four second sub-installation spaces 312 as shown in the figure is selected, one of the three hydrogen bottles 9 can be installed in the first sub-installation space 311 of the bottom layer, the other two can be installed in the second sub-installation space 312 of the middle layer, and the remaining one can be installed in any one of the two second sub-installation spaces 312 of the top layer.

[0043] In the exemplary embodiments provided in the present disclosure, reference is made to Figures 3 to 6 As shown in the figure, the frame body 3 includes a first horizontal crossbeam 33 extending along the horizontal transverse direction, a first horizontal longitudinal beam 34 extending along the horizontal longitudinal direction, and a vertical beam 35 extending along the vertical direction. The first horizontal crossbeam 33, the first horizontal longitudinal beam 34 and the vertical beam 35 are staggered in pairs to separate the interior of the frame body 3 into a first installation space 31 and a second installation space 32 that are independent of each other. Through such an arrangement, the frame body 3 can be composed of various beams, which not only meets the structural strength requirements of the frame body 3, but also can achieve lightweighting.

[0044] In the exemplary embodiments provided by the present disclosure, continue to refer to Figures 3 to 6 As shown in , when the vehicle is accelerating, the frame body 3 and the hydrogen bottle 9 and electrical components installed in the frame body 3 will lean backward away from the cab due to inertia, and when decelerating or braking, the frame body 3 and the hydrogen bottle 9 and electrical components installed in the frame body 3 will lean forward toward the cab side due to inertia. This will cause the side of the frame body 3 away from the cab to be subjected to greater force when the vehicle is accelerating, and the side of the frame body 3 close to the cab to be subjected to greater force when decelerating or braking. Therefore, in order to ensure the structural strength of the frame body 3, the frame body 3 can also include a first main beam 36, which is arranged in pairs and extends in the vertical direction. The paired first main beams 36 are symmetrically arranged on both sides of the frame body 3 along the horizontal longitudinal direction and are fixedly connected to the first horizontal cross beam 33 on the same side of the frame body 3. Through such an arrangement, the frame body 3 can be structurally reinforced from both sides in the horizontal longitudinal direction. In this way, even when the vehicle is accelerating, decelerating or braking, it can be ensured that the frame body 3 has sufficient structural strength. Here, the first main beam 36 can be ensured to have a high structural strength by selecting the material, forming method, etc. For example, the material of the first main beam 36 can be alloy steel, and the forming method can be an integral forming method.

[0045] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 6As shown in , the frame body 3 can also include an extension beam 37, which is arranged near the second sub-beam 22 and perpendicular to the first main beam 36 and the first horizontal crossbeam 33, and the extension beam 37 extends from the intersection of the first horizontal crossbeam 33 and the first main beam 36 toward a direction away from the frame body 3. The frame body 3 also includes a first support beam 38 and a second support beam 39, which are respectively arranged on both sides of the frame body 3 along the horizontal longitudinal direction, wherein one end of the first support beam 38 is fixedly connected to the first sub-beam 21, and the other end is fixedly connected to the first main beam 36 located above the first sub-beam 21, and one end of the second support beam 39 is fixedly connected to the extension beam 37, and the other end is fixedly connected to the first main beam 36 located above the second sub-beam 22.

[0046] As can be seen from the foregoing analysis, when a vehicle is accelerating, decelerating, or braking, the side of the frame body 3 that is away from the cab or the side that is close to the cab will be subjected to greater force due to inertia. Therefore, in order to further strengthen the structure of the frame body 3 in the horizontal and longitudinal directions, the present disclosure further strengthens the structure of the frame body 3 in the horizontal and longitudinal directions by providing the above-mentioned first support beam 38 and second support beam 39, and making the first support beam 38 and second support beam 39 form a stable triangular structure with the first main beam 36 and other beams on the corresponding side. Specifically, the first support beam 38 forms a stable triangular structure with the first sub-beam 21 and the first main beam 36 located above the first sub-beam 21, thereby strengthening the structure of the frame body 3 on the side close to the cab in the frame body 3, while the second support beam 39 forms a stable triangular structure with the extension beam 37 and the first main beam 36 located above the extension beam 37, thereby strengthening the structure of the frame body 3 on the side away from the cab in the frame body 3.

[0047] Among them, the setting of the extension beam 37 is, on the one hand, to cooperate with the first main beam 36 and the second support beam 39 above to form a stable triangular structure, so as to strengthen the structure of the frame body 3 on the side of the frame body 3 away from the cab. On the other hand, the setting of the extension beam 37 can realize the connection between the frame body 3 and the electrical component bracket 5. Specifically, the frame body 3 and the electrical component bracket 5 are connected to the second sub-beam 22 through the extension beam 37. In addition, since the extension beam 37 extends toward the side away from the frame body 3 and is connected to the second sub-beam 22, that is, the connection position between the frame body 3 and the electrical component bracket 5 is located outside the frame body 3, compared with setting the connection position between the frame body 3 and the electrical component bracket 5 inside the frame body 3, this setting can reduce interference from the structure of the frame body 3, thereby making the operation of the staff more convenient.

[0048] Among them, when the vehicle is decelerating or braking, due to the effect of inertia, the frame body 3 will tilt forward toward the side where the cab is located. According to the above analysis, in order to facilitate wiring, the second installation space 32 can be set on the side of the first sub-installation space 311 close to the power battery, and the remaining multiple second sub-installation spaces 312 are arranged in sequence above the first sub-installation space 311 and the second installation space 32 in the vertical direction, and the power battery is set on the side of the frame body 3 away from the cab. Among them, the hydrogen bottle 9 is set in the first sub-installation space 311 and multiple second sub-installation spaces 312 through the hydrogen bottle bracket 4, and the electrical component is set in the second installation space 32 through the electrical component bracket 5. In this way, due to the multiple hydrogen The hydrogen storage system composed of the bottle 9 has a large mass and a high center of gravity, while the electrical component bracket 5 and the electrical components arranged thereon have a small mass and a low center of gravity. Therefore, when setting the first support beam 38 and the second support beam 39, the support position of the support beam can be determined according to the center of gravity of the structure supported by the support beam, that is, the support height of the first support beam 38 on the corresponding first main beam 36 can be set higher than the support height of the second support beam 39 on the corresponding first main beam 36. In other words, the support height of the first support beam 38 on the first main beam 36 above the first sub-beam 21 can be set higher than the support height of the second support beam 39 on the first main beam 36 above the second sub-beam 22.

[0049] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 7 As shown in the figure, the electrical component bracket 5 may include a second main beam 51, a second horizontal longitudinal beam 52 and a plurality of mounting brackets 53. The second horizontal longitudinal beam 52 extends in the horizontal longitudinal direction and is arranged parallel to the second sub-beam 22. The second main beam 51 extends in the horizontal transverse direction and is staggered with the second sub-beam 22 and the second horizontal longitudinal beam 52. A plurality of mounting brackets 53 are arranged in sequence on the second main beam 51 in the horizontal transverse direction. Through such an arrangement, on the one hand, the staggered arrangement of the second main beam 51 and the second horizontal longitudinal beam 52 can be utilized to form an installation base with a certain structural strength and lightness, so as to set the mounting bracket 53 on the installation base. On the other hand, since the plurality of mounting brackets 53 are arranged in sequence in the horizontal transverse direction, the second installation space 32 can be fully and reasonably utilized in the horizontal transverse direction, and most of the electrical components in the vehicle can be concentrated in this space to facilitate the management and maintenance of various electrical components in the vehicle.

[0050] In addition, since the first sub-installation space 311 and the second installation space 32 are of the same size, the second installation space 32 also has a larger size in the height direction. In order to make full use of this space of the second installation space 32 in the height direction, the mounting frames 53 can be set in at least two rows, and at least two rows of mounting frames 53 can be arranged in sequence along the vertical direction, wherein the mounting frames 53 in the upper row can be connected to the second sub-beam 22 or the mounting frames 53 in the lower row.

[0051] The installation method of the electrical components in the above-mentioned mounting racks 53 can be flexibly set according to actual conditions, and the present disclosure does not limit this. Figure 7 As shown, when two rows of mounting racks 53 are provided, a DC / DC converter, a power electronics unit (PEU, full name Power Electronics Unit) and a battery can be sequentially arranged on the three mounting racks 53 in the lower row, while a battery distribution box (BDU, full name Battery Disconnect Unit) and a low-voltage fuse box for the entire vehicle can be sequentially arranged on the mounting racks 53 in the upper row.

[0052] In the above embodiment, continue to refer to Figure 7 As shown in , in order to further improve the structural strength of the electrical component bracket 5, the electrical component bracket 5 can be provided with a pair of second horizontal beams 54, the pair of second horizontal beams 54 are symmetrically arranged on the side away from each other of the pair of second sub-beams 22 and extend toward the side away from each other, the second horizontal beams 54 are perpendicular to the second sub-beam 22 and the second horizontal longitudinal beam 52 and are fixedly connected to the second sub-beam 22 and the second horizontal longitudinal beam 52 respectively.

[0053] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 6 As shown in FIG, the second sub-beam 22 can be located below the extension beam 37 and extend toward the first sub-beam 21. The second sub-beam 22 and the extension beam 37 are connected by fasteners. This arrangement facilitates the connection and fixation between the second sub-beam 22 and the extension beam 37. On the other hand, since the second sub-beam 22 is located outside the frame body 3, the frame body 3 can be easily removed from the vehicle frame 1. The fasteners can be bolts, nuts, etc.

[0054] In addition, reference Figure 2As shown in the figure, in order to facilitate the installation of the hydrogen bottle 9, a hydrogen bottle holder 4 can be provided, including a bottle holder 41 and a hoop 42, wherein the bottle holder 41 is arranged between two adjacent first horizontal beams 33 of the frame body 3, and a mounting slot is formed above the bottle holder 41, and a hoop 42 is provided in the mounting slot. In this way, when the hydrogen bottle 9 is installed on the hydrogen bottle holder 4, the hoop 42 can be untied first, and then the hydrogen bottle 9 can be placed in a suitable position in the mounting slot, and then the hydrogen bottle 9 can be clamped and fixed by the hoop 42.

The vehicle frame 1 has a top surface 11 and an outer side surface 12 arranged away from its own central axis. The first sub-beams 21 are arranged in pairs and are constructed as first U-shaped beams 211. The first U-shaped beams 211 have a first bottom surface 211a and two first side surfaces 211b arranged on both sides of the first bottom surface 211a and extending perpendicularly to the first bottom surface 211a. The paired first sub-beams 21 are arranged symmetrically along the horizontal transverse direction and the first bottom surfaces 211a of the paired first sub-beams 21 are arranged toward the side away from each other. The first sub-beams 21 are located at the frame body 3. The first side surface 211b is disposed between the frame body 3 and the top surface 11 and is welded to the frame body 3.

The first auxiliary connecting plate 6 is connected to the first bottom surface 211a and the outer side surface 12 via fasteners. In this way, due to the provision of the first auxiliary connecting plate 6, on the one hand, the force-bearing area of ​​the vehicle frame 1 and the first auxiliary beam 21 during connection can be increased to improve the connection strength. On the other hand, this also allows the connection between the first auxiliary beam 21 and the frame 1 to be operated on the outside of the vehicle frame 1, which is more convenient. The fasteners may be bolts, nuts, etc.

[0056] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 6 、 Figure 7 、 Figure 9 as well as Figure 10As shown in , in order to achieve the connection between the second subbeam 22 and the frame 1 and between the first subbeam 21, the second subbeam 22 and the frame 1, the vehicle can be provided with a main connecting plate 8 and a second subbeam 7, the second subbeams 22 are arranged in pairs and are constructed as a second U-shaped beam 221, the second U-shaped beam 221 has a second bottom surface 221a and two second side surfaces 221b arranged on both sides of the second bottom surface 221a and extending perpendicular to the second bottom surface 221a, wherein the paired second subbeams 22 are arranged symmetrically in the horizontal transverse direction and the second bottom surfaces 221a of the paired second subbeams 22 are arranged toward the side away from each other, the second subbeam 22 is located between the electrical component bracket 5 and the top surface 11 and one second side surface 221b is arranged in contact with the electrical component bracket 5 and the extension beam 37 The electrical component bracket 5 and the extension beam 37 are arranged in sequence along the horizontal longitudinal direction. Therefore, a portion of the second side surface 221b is welded to the electrical component bracket 5, and another portion is connected to the extension beam 37 via fasteners. The other second side surface 221b is disposed in affixed relation to the top surface 11. The second auxiliary connecting plate 7 is disposed in affixed relation to the second bottom surface 221a and extends toward the outer side surface 12. The second auxiliary connecting plate 7 is connected to the second bottom surface 221a and the outer side surface 12 via fasteners. In this way, the provision of the second auxiliary connecting plate 7 can, on the one hand, increase the force-bearing area of ​​the connection between the vehicle frame 1 and the second auxiliary beam 22 to improve the connection strength. On the other hand, this also allows the connection between the second auxiliary beam 22 and the vehicle frame 1 to be operated from the outside of the vehicle frame 1, thereby increasing convenience. The fasteners can be bolts, nuts, etc.

[0057] To further facilitate the connection between the first and second sub-beams 21, 22, and the vehicle frame 1, the first and second bottom surfaces 211a, 221a, and the outer side surface 12 can be aligned. A main connecting plate 8 is positioned flush against the outer side surface 12 and extends toward the first and second bottom surfaces 211a, 221a. The main connecting plate 8 is connected to the outer side surface 12, the first and second bottom surfaces 211a, 221a via fasteners. Furthermore, the provision of the main connecting plate 8 enhances the overall connection strength between the frame body 3, the electrical component bracket 5, and the vehicle frame 1. The fasteners can be bolts, nuts, or the like.

[0058] In the above embodiment, in order to further improve the connection strength, a suitable number of reinforcing ribs may be provided on the main connecting plate 8 , the first auxiliary connecting plate 6 and the second auxiliary connecting plate 7 .

[0059] In the above embodiment, since the U-shaped beam is easy to process and has a thin wall and light weight, the first sub-beam 21 and the second sub-beam 22 are constructed as U-shaped beams. This can be beneficial to the lightweight design of the overall structure of the vehicle on the one hand, and can also facilitate the installation between the first sub-beam 21 and the second sub-beam 22 and the frame 1, as well as the installation between the second sub-beam 22 and the frame body 3 on the other hand.

[0060] In the exemplary embodiments provided in this disclosure, in order to improve the structural strength of the sub-beam 2, any appropriate improvement can be made to the sub-beam 2, for example, adding a reinforcing plate or reinforcing ribs to the sub-beam 2. The specific modification can be flexibly selected according to actual conditions, and this disclosure does not limit this. For example, when the sub-beam 2 structure is improved by adding a reinforcing plate, there are three possible implementation methods:

[0061] In the first possible implementation, refer to Figure 8 As shown in , a first reinforcing plate 211 c may be provided on the first sub-beam 21 , and the first reinforcing plate 211 c is provided perpendicular to the length direction of the first sub-beam 21 .

[0062] In the second possible implementation, refer to Figure 7 As shown in , a second reinforcing plate 221 c may be provided on the second sub-beam 22 , and the second reinforcing plate 221 c is provided perpendicular to the length direction of the second sub-beam 22 .

[0063] In the third possible implementation, refer to Figure 7 and Figure 8 As shown in , the first sub-beam 21 may be provided with a first reinforcing plate 211c, which is arranged perpendicular to the length direction of the first sub-beam 21. Furthermore, the second sub-beam 22 may be provided with a second reinforcing plate 221c, which is arranged perpendicular to the length direction of the second sub-beam 22.

[0064] In the above three implementations, in order to further improve the structural strength of the first sub-beam 21 or the second sub-beam 22, the number of the first reinforcing plates 211c and the second reinforcing plates 221c can be set to multiple. In this way, when the number of the first reinforcing plates 211c is multiple, the multiple first reinforcing plates 211c can be arranged at intervals along the length direction of the first sub-beam 21, and when the number of the second reinforcing plates 221c is multiple, the multiple second reinforcing plates 221c can be arranged at intervals along the length direction of the second sub-beam 22.

[0065] For example, when there are four first reinforcing plates 211c, the four first reinforcing plates 211c are spaced apart along the length direction of the first sub-beam 21, wherein the spacing between two adjacent first reinforcing plates 211c can be reasonably set based on the actual strength requirements of various parts on the first sub-beam 21. When there are three second reinforcing plates 221c, the three second reinforcing plates 221c are spaced apart along the length direction of the second sub-beam 22, wherein the spacing between two adjacent second reinforcing plates 221c can be reasonably set based on the actual strength requirements of various parts on the second sub-beam 22.
