[0003] [Patent Document 1] Patent Publication No. 2022-108125 Summary of the Invention [Problem to be solved by the invention]
[0004] Among vehicles, there are vehicles that include a body, a plurality of hydrogen tanks arranged in parallel, a plurality of first neck blocks that support each of the hydrogen tanks at one end in the longitudinal direction, a plurality of second neck blocks that support each of the hydrogen tanks at the other end in the longitudinal direction, a first body part that is arranged below the lower ends of the hydrogen tanks, supports the first neck blocks, and is attached to the body, and a second body part that is arranged below the lower ends of the hydrogen tanks, supports the second neck blocks, and is attached to the body. In the case of this vehicle, it is necessary to ensure the minimum ground clearance of the vehicle based on the first body part and the second body part. In order to ensure the minimum ground clearance of the vehicle, the size of the multiple hydrogen tanks must be reduced.
[0005] This specification provides a technology that can ensure both the size of multiple hydrogen tanks and the minimum ground clearance of the vehicle. [Means for solving the problem]
[0006] In a first aspect of the present technology, a vehicle comprises a body including a ladder frame, a plurality of hydrogen tanks arranged in parallel between the ladder frame, a plurality of first neck blocks each supporting the plurality of hydrogen tanks at one end in the longitudinal direction, a plurality of second neck blocks each supporting the plurality of hydrogen tanks at the other end in the longitudinal direction, a first body part arranged above the lower ends of the plurality of hydrogen tanks, supporting the plurality of first neck blocks, and attached to the body, and a second body part arranged above the lower ends of the plurality of hydrogen tanks, supporting the plurality of second neck blocks, and attached to the body.
[0007] In the above vehicle, the minimum ground clearance of the vehicle can be secured based on the lower ends of the multiple hydrogen tanks. Therefore, compared to a configuration in which the minimum ground clearance of the vehicle is secured based on the first and second body parts that are positioned below the lower ends of the multiple hydrogen tanks, the size of the multiple hydrogen tanks can be increased while securing the minimum ground clearance of the vehicle by the vertical thickness of the first and second body parts. Therefore, it is possible to secure both the size of the multiple hydrogen tanks and the minimum ground clearance of the vehicle. [Brief description of the drawings]
[0008] [Figure 1] FIG. 2 is a top view of a vehicle 2 according to the first embodiment. [Diagram 2] 1 is a front cross-sectional view of a vehicle 2 according to a first embodiment. [Diagram 3] FIG. 11 is a top view of a vehicle 102 according to a second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] (First Example) 1, the vehicle 2 includes a body 10, a plurality of hydrogen tanks 12A-12C, a front mounting unit 14, and a rear mounting unit 16. The vehicle 2 is a fuel cell vehicle or a hydrogen engine vehicle that is driven by hydrogen as fuel.
[0010] The body 10 includes a ladder frame 20. The ladder frame 20 includes a right frame 22 and a left frame 24. The right frame 22 and the left frame 24 extend in the front-rear direction.
[0011] The multiple hydrogen tanks 12A to 12C are arranged in parallel between the right frame 22 and the left frame 24 of the ladder frame 20. The longitudinal direction of the multiple hydrogen tanks 12A to 12C is aligned along the front-rear direction.
[0012] The front mounting unit 14 includes a plurality of front neck blocks 30A to 30C, two mounts 32A and 32B, and a front body part 34. The front neck blocks 30A to 30C support the hydrogen tanks 12A to 12C at their front ends, respectively. The front body part 34 extends in the left-right direction between the right frame 22 and the left frame 24 of the ladder frame 20. The right end of the front body part 34 is attached to the right frame 22 via a mount 32A, and the left end is attached to the left frame 24 via a mount 32B. As shown in FIG. 2, the mounts 32A and 32B include anti-vibration rubber 33. The mounts 32A and 32B absorb vibrations of the body 10 and torsional displacement of the body 10. The front neck blocks 30A to 30C are fixed to the upper surface of the front body part 34 by screws. The front body component is located above the lower ends of the multiple hydrogen tanks 12A to 12C. The lower ends of the multiple hydrogen tanks 12A to 12C are located below the front body component, the right frame 22, and the left frame .
[0013] As shown in FIG. 1, the rear mounting unit 16 includes a plurality of rear neck blocks 40A-40C, two mounts 42A, 42B, and a rear body part 44. The rear neck blocks 40A-40C support the hydrogen tanks 12A-12C at their rear ends, respectively. The rear body part 44 extends in the left-right direction between the right frame 22 and the left frame 24 of the ladder frame 20. The right end of the rear body part 44 is attached to the right frame 22 via a mount 42A, and the left end is attached to the left frame 24 via a mount 42B. The mounts 42A, 42B have the same configuration as the mounts 32A, 32B. The rear neck blocks 40A-40C are fixed to the upper surface of the rear body part 44 by screws. Like the front body part 34, the rear body part 44 is disposed above the lower ends of the multiple hydrogen tanks 12A-12C. It is sufficient that the front body part 34 and the rear body part 44 are disposed between the upper and lower ends of the multiple hydrogen tanks 12A-12C.
[0014] As described above, the vehicle 2 comprises a body 10 including a ladder frame 20, a plurality of hydrogen tanks 12A-12C arranged in parallel between the ladder frame 20, a plurality of front neck blocks 30A-30C (an example of a "plurality of first neck blocks") that respectively support the plurality of hydrogen tanks 12A-12C at their front ends (an example of "one end in the longitudinal direction"), and a plurality of rear neck blocks 40A-40C (an example of a "plurality of rear neck blocks") that respectively support the plurality of hydrogen tanks 12A-12C at their rear ends (an example of "the other end in the longitudinal direction"). The vehicle body 10 includes a front body part 34 (an example of a "first body part") that is arranged above the lower ends of the multiple hydrogen tanks 12A-12C, supports the multiple front neck blocks 30A-30C, and is attached to the body 10; and a rear body part 44 (an example of a "second body part") that is arranged above the lower ends of the multiple hydrogen tanks 12A-12C, supports the multiple rear neck blocks 40A-40C, and is attached to the body 10.
[0015] In the above-described vehicle 2, the minimum ground clearance of the vehicle 2 can be ensured based on the lower ends of the multiple hydrogen tanks 12A-12C. Therefore, compared to a configuration in which the minimum ground clearance of the vehicle is ensured based on front and rear body parts that are positioned below the lower ends of the multiple hydrogen tanks, the size of the multiple hydrogen tanks 12A-12C can be increased while ensuring the minimum ground clearance of the vehicle 2 by the vertical thickness of the front and rear body parts 34 and 44. Therefore, it is possible to ensure both the size of the multiple hydrogen tanks 12A-12C and the minimum ground clearance of the vehicle 2.
[0016] (Second Example) A vehicle 102 according to the second embodiment will be described with reference to Fig. 3. Note that components common to the embodiments will be given the same reference numerals and descriptions thereof will be omitted.
[0017] 3, the body 110 includes a ladder frame 20 having a right frame 22 and a left frame 24, a front auxiliary frame 126, and a rear auxiliary frame 128. The front auxiliary frame 126 and the rear auxiliary frame 128 extend in the left-right direction between the right frame 22 and the left frame 24. The front auxiliary frame 126 is disposed forward of the multiple hydrogen tanks 12A-12C. The rear auxiliary frame 128 is disposed rearward of the multiple hydrogen tanks 12A-12C.
[0018] The front attachment unit 114 includes a plurality of front neck blocks 30A to 30C, two mounts 132A and 132B, and a front body part 34. The front body part 34 is attached to the front auxiliary frame 126 via the mounts 132A and 132B. The mount 132A is disposed between the right front neck block 30A and the central front neck block 30B, and the mount 132B is disposed between the central front neck block 30B and the left front neck block 30C.
[0019] The rear mounting unit 116 includes a plurality of rear neck blocks 40A-40C, two mounts 142A, 142B, and a rear body part 44. The rear body part 44 is attached to the rear auxiliary frame 128 via the mounts 142A, 142B. The mount 142A is disposed between the right rear neck block 40A and the central rear neck block 40B, and the mount 142B is disposed between the central rear neck block 40B and the left rear neck block 40C. In this embodiment, the front body part 34 and the rear body part 44 are disposed above the lower ends of the plurality of hydrogen tanks 12A-12C. Therefore, the configuration of this embodiment can also achieve the same effects as the vehicle 2 of the first embodiment. [Explanation of symbols]
