When installing the functional device, first fit the first base 114 with the corresponding position of the functional device, and then pass the second fastener through the third mounting hole 116 and fixedly connect it to the functional device to fix the first bracket 11 on the functional device.

[0048] Moreover, the second bracket 12 is fixedly connected to the vehicle body, and then the functional device is pre - installed at the installation point. After the first bracket 11 and the second bracket 12 are aligned with each other, the first fastener passes through the first mounting hole 113 and the second mounting hole 123 and is fixedly connected to the second bracket 12, thereby completing the installation and fixation of the functional device.

[0052] When installing the functional device, first fit the first base 114 to the corresponding position of the functional device, and then pass the second fastener through the third mounting hole 116 and fixedly connect it to the functional device to fix the first bracket 11 on the functional device; and, fix the second bracket 12 to the vehicle body, then pre - install the functional device to the installation point. After the second bracket 12 and the second bracket 12 are aligned with each other, the first fastener passes through the first mounting hole 113 and the second mounting hole 123 and is fixedly connected to the second bracket 12, thus completing the installation and fixation of the functional device.

[0054] A vehicle according to an embodiment of the second aspect of the present invention includes: two frame longitudinal beams 22; a fuel cell 21 installed between the two frame longitudinal beams 22; two drop - mounted bracket assemblies 10, and the two drop - mounted bracket assemblies 10 are respectively connected between the two sides of the fuel cell 21 in the third direction and the two frame longitudinal beams 22.

[0055] In the prior art, for the installation and fixation of the fuel cell 21 engine, the bracket used to fix the fuel cell 21 engine is in the form of a traditional engine inclined plane bracket plus a soft pad for shock absorption. Its entire layout is under the front of the vehicle. Among them, the hydrogen cylinder and the DC-DC module arranged at the rear side, as well as the radiator arranged facing the wind in the front, limit the moving distance of the fuel cell 21 in the front and rear (x direction). And for the whole vehicle, the maintenance requirements of the end customers and the maintenance station for the fuel cell 21 include the requirement of lowering the upper body. It is necessary to disassemble the front radiator and the radiator fan and remove the hydrogen cylinder and the DCDC and its wiring harness at the rear side, and then leave a distance at both ends of the fuel cell 21 before lowering it; the operation is not simple and the efficiency is low.

[0056] Combined with Figure 4 As shown, the drop-installation bracket assembly 10 of the present utility model is applied to the installation and fixation of the fuel cell 21. Two drop-installation bracket assemblies 10 are used. One is arranged between the left side of the fuel cell 21 and the corresponding frame cross beam, and the other drop-installation bracket assembly 10 is arranged between the right side of the fuel cell 21 and the corresponding frame cross beam. One of the first brackets 11 is connected to the left side of the fuel cell 21, and the other first bracket 11 is connected to the right side of the fuel cell 21; one of the second brackets 12 is connected to the left frame longitudinal beam 22, and the other second bracket 12 is connected to the right frame longitudinal beam 22, so as to fixedly connect the fuel cell 21 with the frame longitudinal beams 22 on both left and right sides.

[0057] Combined with Figure 2 and Figure 4 As shown, when installing the fuel cell 21, first fit the first base 114 with the corresponding position of the fuel cell 21, and then pass the second fastener through the third mounting hole 116 and fixedly connect it with the fuel cell 21 to fix the first bracket 11 on the fuel cell 21; and, fixedly connect the second bracket 12 with the frame longitudinal beam 22; then pre-install the fuel cell 21 to the installation position. After the second brackets 12 are aligned with each other, the first fastener passes through the first mounting hole 113 and the second mounting hole 123 and is fixedly connected with the second bracket 12, thereby completing the installation and fixation of the fuel cell 21.

[0058] Combined with Figure 1 and Figure 4As shown in the figure, when disassembling the fuel cell 21, the first fastener is disassembled, so that the first mounting teeth 111 and the second mounting teeth 121 are disengaged, that is, the first bracket 11 and the second bracket 12 are disengaged; the fuel cell 21 is moved in the front-rear direction until the plurality of first mounting teeth 111 are respectively staggered with the plurality of second mounting teeth 121, the first mounting teeth 111 are fitted in the second mounting grooves 122, and the second mounting teeth 121 are fitted in the first mounting grooves 112, so that the first bracket 11 can slide relative to the second bracket 12 in the height direction, so that the fuel cell 21 can fall, thereby disassembling the fuel cell 21 from the vehicle body.

[0059] The relative movement between the fuel cell 21 and the vehicle frame longitudinal beam 22 is restricted by the fixed connection of the first bracket 11 and the second bracket 12.

[0060] When the engine needs to be overhauled or the bottom valve parts need to be replaced, the first fastener is pulled out, and the first mounting teeth 111 and the second mounting teeth 121 are staggered with each other, so that the first bracket 11 falls from the second bracket 12, that is, the fuel cell 21 falls from the vehicle frame longitudinal beam 22. The fuel cell 21 and the vehicle frame longitudinal beam 22 are connected by the drop-mounted bracket assembly 10, which ensures the support of the vehicle frame longitudinal beam 22 for the fuel cell 21 and saves the space of the whole vehicle.

[0061] When the high-pressure radiator, the split DC-DC, and the high-voltage harness of the vehicle controller all occupy limited space for layout, the space in the front-rear direction is fully saved.

[0062] Among them, the drop-mounted bracket assembly 10 can be actually applied to the connection between the axle and the fuel cell 21 in a heavy truck, and is connected to the vehicle frame longitudinal beam 22 through the fourth mounting hole 126 to ensure relative stability in the three directions of the front-rear direction, the left-right direction, and the height direction, so as to ensure the fixation and connection of the fuel cell 21 and the whole vehicle.
