[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figure 1-Figure 4 The installation device of the utility model is described.

[0034] Specifically, the mounting device is used to mount the air compressor 5 on the stack housing 2. The mounting device includes a mounting seat 1, a first connecting member 3, a second connecting member 4 and a telescopic member 6.

[0035] The mounting base 1 is connected to the stack housing 2. The stack is the core component of the hydrogen fuel cell system, the place where the electrochemical reaction occurs, and maintains the energy output process of the entire fuel cell system. The stack housing 2 refers to the shell component outside the stack.

[0036] The first connecting member 3 is rotatably connected to the mounting seat 1 . For example, the mounting seat 1 is provided with a protruding structure, and the first connecting member 3 is hingedly connected to the protruding structure. The first connecting member 3 is provided with a first connecting portion connected to the air compressor 5 .

[0037] The second connecting member 4 is connected to the mounting seat 1, and the second connecting member 4 is provided with a second connecting portion connected to the air compressor 5. For example, the first connecting member 3, the second connecting member 4, the mounting seat 1 and the air compressor 5 form a connecting rod mechanism with at least one degree of freedom.

[0038] The telescopic member 6 is configured to be adjustable in length. One end of the telescopic member 6 is rotatably connected to the mounting seat 1 , and the other end of the telescopic member 6 is rotatably connected to the first connecting member 3 .

[0039] The installation device provided in the embodiment of the utility model can be connected to the battery stack housing 2 through the mounting base 1, and is rotatably connected to the mounting base 1 through the first connecting member 3. The second connecting member 4 is connected to the mounting base 1, and the first connecting member 3 is provided with a first connecting part, and the second connecting member 4 is provided with a second connecting part. The air compressor 5 can be connected to the first connecting part and the second connecting part respectively, thereby completing the installation and fixation of the air compressor 5.

[0040] The telescopic member 6 is rotatably connected to the mounting base 1 and the first connecting member 3 respectively. By adjusting the length of the telescopic member 6, the angle of the first connecting member 3 can be adjusted, thereby changing the spacing between the first connecting portion of the first connecting member 3 and the second connecting portion of the second connecting member 4. Therefore, when replacing an air compressor 5 of different specifications and causing the hole spacing of the mounting holes of the air compressor 5 to change, the length of the telescopic member 6 can be adjusted so that both the first connecting portion and the second connecting portion can be connected to the replaced air compressor 5, thereby solving the problem of designing different air compressor 5 brackets due to the different hole spacings of the mounting holes of the air compressor 5, so that the mounting device can adapt to air compressors 5 with different hole spacings.

[0041] In addition, by adjusting the length of the telescopic member 6, the telescopic member 6 drives the air compressor 5 to deflect through the first connecting member 3, thereby achieving the effect of adjusting the installation angle of the air compressor 5. That is, the installation device can adapt to air compressors 5 with different installation hole pitches and can adjust the angle of the air compressor 5.

[0042] In some embodiments provided by the present invention, the mounting base 1 is arranged on the outside of the stack housing 2, and the first connector 3 and the second connector 4 are both arranged on the side of the mounting base 1 away from the stack housing 2. Optionally, the first connector 3 and the second connector 4 include but are not limited to being arranged at intervals, and in this embodiment, the interval arrangement is preferred.

[0043] In some embodiments provided by the present invention, the telescopic member 6 includes a first seat body 601 , a second seat body 602 and a threaded connection member 603 .

[0044] The first seat body 601 is rotatably connected to the mounting seat 1, the second seat body 602 is rotatably connected to the first connecting member 3, and the threaded connecting member 603 connects the first seat body 601 and the second seat body 602 and is used to drive the first seat body 601 and the second seat body 602 to move closer or farther away.

[0045] In this embodiment, the first seat body 601 and the second seat body 602 are connected by a threaded connector 603, and the first seat body 601 and the second seat body 602 are driven to move closer or farther away. On the one hand, the structure of the telescopic member 6 is simple and the cost is low. On the other hand, the threaded connection has a good anti-loosening effect, which can maintain the stability of the telescopic member 6 and prevent the telescopic member 6 from loosening, so that the telescopic member 6 can better fix the first seat body 601, thereby ensuring the stability of the air compressor. Finally, the threaded connection can steplessly adjust the distance between the first seat body 601 and the second seat body 602.

[0046] refer to Figure 2 and Figure 3 As shown, optionally, the threaded connector 603 includes a bolt, for example, a limit block is provided on the second seat body 602, a through slot is provided on the limit block, the bolt passes through the through slot and is threadedly connected to the first seat body 601, and the head of the bolt abuts against the limit block. Further, the threaded connector 603 also includes a nut, the nut is threadedly connected to the bolt, and the heads of the nut and the bolt abut against the two sides of the limit block respectively. Alternatively, a threaded hole is provided on the first seat body 601, and a through hole is provided on the second seat body 602, the threaded connector 603 is threadedly connected to the threaded hole on the first seat body 601, and passes through the through hole on the second seat body 602 and is locked by a nut.

[0047] Of course, the threaded connector 603 is not limited to a bolt. For example, in other embodiments of the present invention, the threaded connector 603 includes a screw rod having two sections of threads with opposite rotation directions, which are threadedly connected to the first seat body 601 and the second seat body 602 respectively.

[0048] refer to Figure 4 As shown, in some embodiments provided by the present invention, one of the first seat body 601 and the second seat body 602 is provided with a slider 604 , and the other is provided with a slide groove 605 slidably matched with the slider 604 .

[0049] In this embodiment, the first seat body 601 and the second seat body 602 form a sliding fit through the slider 604 and the slide groove 605. When the telescopic member 6 is subjected to a bending moment, the bending moment acts on the slider 604 and the slide groove 605, but does not act on the threaded connection 603, thereby reducing the problem of bending, deformation, breakage or loosening of the threaded connection 603 and extending the service life of the telescopic member 6.

[0050] Of course, the telescopic member 6 can also be an electric push rod, a pneumatic cylinder or an oil cylinder.

[0051] In some embodiments provided by the utility model, the mounting device also includes a first bolt 7, and a cross groove 101 is provided on the mounting base 1 for the first bolt 7 to pass through. The first bolt 7 passes through the cross groove 101 and is connected to the battery stack housing 2, for example, the first bolt 7 is threadedly connected to the battery stack housing 2 or connected by a nut.

[0052] In this embodiment, the mounting seat 1 can be adjusted in position in two directions relative to the first bolt 7 through the cross slot 101 , thereby achieving the effect of adjusting the installation position of the air compressor 5 on the stack housing 2 .

[0053] In some embodiments provided by the present utility model, the mounting device further includes a first shock absorbing pad 8, which is sandwiched between the head of the first bolt 7 and the mounting seat 1. In this embodiment, by providing the first shock absorbing pad 8 between the head of the first bolt 7 and the mounting seat 1, the vibration transmission between the stack housing 2 and the mounting seat 1 can be reduced, thereby reducing the vibration of the stack housing 2 and reducing noise.

[0054] In some embodiments provided by the present utility model, the first connecting member 3 and the second connecting member 4 are provided in pairs in two groups, and the two groups of the first connecting members 3 and the second connecting members 4 are spaced and arranged in mirror symmetry. In this embodiment, by providing two groups of the first connecting members 3 and the second connecting members 4 to connect the air compressor 5, the connection strength between the air compressor 5 and the mounting seat 1 can be enhanced, thereby forming a better fixing effect on the air compressor 5.

[0055] In some embodiments provided by the present invention, the first connection portion includes a first connection hole 301 and a first threaded member, and the first threaded member passes through the first connection hole 301 and is connected to the air compressor. With such a configuration, the structure of the first connection portion is simple.

[0056] In some embodiments provided by the present invention, the second connection portion includes a second connection hole 401 and a second threaded member, and the second threaded member passes through the second connection hole 401 and is connected to the air compressor. With such a configuration, the structure of the first connection portion is simple.

[0057] In some embodiments provided by the present invention, at least one of the first connecting hole and the second connecting hole is configured as a long hole.

[0058] In this embodiment, for example, when the second connection portion is fixedly connected to the mounting seat 1, and one of the first connection hole and the second connection hole is set as a long hole, after the air compressor 5 is connected to the first connection hole and the second connection hole, the angle of the first connection member 3 can be adjusted by adjusting the length of the telescopic member 6, so that the air compressor 5 is driven to deflect by the first connection member 3, thereby achieving the effect of adjusting the installation angle of the air compressor 5. At this time, the number of degrees of freedom of the connecting rod mechanism is 1, and if the second connection member 4 is rotationally connected to the mounting seat, the number of degrees of freedom of the connecting rod mechanism is 2.

[0059] For example, when the second connecting portion is fixedly connected to the mounting seat 1, and both the first connecting hole and the second connecting hole are configured as long holes, Figure 3 As shown, by adjusting the length of the telescopic member 6, the angle of the air compressor 5 can be adjusted. In addition, by adjusting the length of the telescopic member 6 and sliding the air compressor 5 along the first connection portion and the second connection portion, the distance between the air compressor 5 and the mounting seat 1 can be adjusted, and finally the distance between the air compressor 5 and the stack housing 2 can be adjusted, that is, the installation device can adapt to air compressors 5 with different mounting hole spacings, adjust the angle of the air compressor 5, and adjust the distance between the air compressor 5 and the stack housing 2, so that the installation device can meet the diverse installation requirements of the air compressor 5. At this time, the number of degrees of freedom of the connecting rod mechanism is 2. If the second connecting member 4 is rotatably connected to the mounting seat, the number of degrees of freedom of the connecting rod mechanism is 3.

[0060] In some embodiments provided by the present invention, the first threaded member or the second threaded member includes a second bolt 9. The mounting device further includes a second shock-absorbing pad 10.

[0061] The second bolt 9 passes through the first connection part or the second connection part and is connected to the air compressor 5. For example, the second bolt 9 is threadedly connected to the mounting hole of the air compressor 5, or the second bolt 9 passes through the mounting hole of the air compressor 5 and is threadedly connected to the nut. The second shock-absorbing pad 10 is arranged between the head of the second bolt 9 and the first connecting member 3 or the second connecting member 4.

[0062] In this embodiment, by providing a second shock-absorbing pad 10 between the second bolt 9 and the first connecting member 3 or the second connecting member 4, the vibration transmitted from the air compressor 5 to the mounting base 1 through the first connecting member 3 or the second connecting member 4 can be reduced, thereby ultimately reducing the vibration effect on the stack casing 2.

[0063] Optionally, the first shock-absorbing pad 8 or the second shock-absorbing pad 10 is configured as a rubber pad or a silicone pad.

[0064] In some embodiments provided by the utility model, the second connecting member 4 and the mounting seat 1 are configured as an integral structure. With such a configuration, the connection strength between the second connecting member 4 and the mounting seat 1 is high, and the overall performance is better. And when installing the air compressor 5, the air compressor 5 can be first connected to the second connecting portion of the second connecting member 4, so that the second connecting member 4 supports the air compressor 5, and then the angle or position of the air compressor 5 is adjusted, and the first connecting portion of the first connecting member 3 is adjusted to align with the air compressor 5, thereby improving the installation convenience of the air compressor 5. Optionally, the second connecting member 4 and the mounting seat 1 are configured as a welded integral structure, a cast integral structure, or a forged integral structure.

[0065] In some embodiments provided by the present invention, the second connecting member 4 is rotatably connected to the mounting seat 1. Accordingly, the first connecting hole and the second connecting hole can both be set as round holes, and the number of degrees of freedom of the connecting rod mechanism is 1; the first connecting hole and the second connecting hole can both be set as long holes, and the number of degrees of freedom of the connecting rod mechanism is 3; the first connecting hole and the second connecting hole can also be set as one of the round holes and the other of the long holes, and the number of degrees of freedom of the connecting rod mechanism is 2.
