It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] As mentioned above, the first aspect of the utility model provides an auxiliary installation device for a hydrogen fuel cell, which is used to fix the hydrogen fuel cell in a battery compartment of a forklift in multiple directions to ensure the stability of the hydrogen fuel cell in the battery compartment of the forklift.

[0029] like Figure 1 , 4 As shown in Figures 5 and 6, the auxiliary installation device of the hydrogen fuel cell comprises a front guard plate 3, front and rear limit blocks 4 and left and right limit blocks 5. The front guard plate 3 is provided with mutually parallel opposite sides, which respectively fit the front wall of the fuel cell 1 and the front cavity wall of the battery compartment 2; the front and rear limit blocks 4 have mutually perpendicular side edges, which respectively fit the front cavity wall of the battery compartment 2 and the left wall of the fuel cell 1; the left and right limit blocks 5 have mutually perpendicular fixing plates, which respectively fit the right wall of the fuel cell 1 and the front cavity wall of the battery compartment 2;

[0030] Among them, the front guard plate 3, the front and rear limit blocks 4 and the left and right limit blocks 5 are all arranged in the battery compartment 2 and can respectively contact the surrounding walls of the fuel cell 1, and the front and rear limit blocks 4 and the left and right limit blocks 5 are respectively arranged on both sides of the front guard plate 3.

[0031] In the present utility model, the "front", "rear", "left" and "right" refer to the "front", "rear", "left" and "right" of a forklift. A common forklift battery compartment 2 is in the shape of a square groove with an opening facing upward and front and rear walls higher than left and right walls. For ease of loading, the volume of the fuel cell 1 is usually smaller than the volume of the battery compartment 2. When the fuel cell 1 is hoisted into the battery compartment 2, pay attention to keeping the rear wall of the fuel cell 1 close to the rear wall of the battery compartment 2, the right wall of the fuel cell 1 close to the right wall of the battery compartment 2, the front guard plate 3 and the front and rear limit blocks 4 limit the front and left sides of the fuel cell 1 respectively, and the left and right limit blocks 5 limit the front and right sides of the fuel cell 1, thereby fixing the fuel cell 1 in the battery compartment 2 to avoid hidden dangers caused by shaking of the fuel cell 1.

[0032] Since the front and rear walls of the battery compartment 2 of the forklift are higher than the left and right walls, it is necessary to limit and fix the upper part of the left and right walls of the fuel cell 1 exposed to the battery compartment 2. In one embodiment of the utility model, the left and right limit blocks 5 are set to a "T" shape, and the left and right limit blocks 5 have a first fixing plate 51 and a second fixing plate 52 that are perpendicular to each other. The thickness of the first fixing plate 51 is less than the distance between the front wall of the fuel cell 1 and the front wall of the battery compartment 2, so that one end of the first fixing plate 51 can be inserted between the front wall of the fuel cell 1 and the front wall of the battery compartment 2 and fit the front wall of the fuel cell 1 and the front wall of the battery compartment 2, thereby limiting the front of the part of the fuel cell 1 exposed to the left and right walls of the battery compartment 2.

[0033] The other end of the first fixing plate 51 is provided with a plurality of waist-shaped holes along a direction perpendicular to the front cavity wall of the battery compartment body 2. The waist-shaped holes are used to install bolts and realize the relative movement of the left and right limit blocks 5 and the bolts. The bolts fix the first fixing plate 51 to the front cavity wall of the upper part of the battery compartment body 2. When the fuel cell 1 has an unfixed size in the left and right directions, the position of the waist-shaped holes contacting the bolts is adjusted and the bolts are tightened to realize the limiting fixation of fuel cells 1 of different sizes by the utility model, thereby enhancing the versatility of the utility model.

[0034] The side wall of the second fixing plate 52 fits the side wall of the fuel cell 1, and the right-angled surfaces formed by the first fixing plate 51 and the second fixing plate 52 respectively fit the right-angled surfaces formed by the front wall and the right wall of the fuel cell 1, thereby achieving right-side limiting and upper front limiting of the fuel cell 1.

[0035] In the utility model, the front guard plate 3 is arranged at the front part of the battery compartment 2, so that the front guard plate 3 is installed between the fuel cell 1 and the front cavity wall of the battery compartment 2. The thickness of the front guard plate 3 fills the gap between the fuel cell 1 and the front cavity wall of the battery compartment 2. The opposite sides of the front guard plate 3 parallel to each other are respectively attached to the front wall of the fuel cell 1 and the front cavity wall of the battery compartment 2, thereby realizing the limitation of the front and rear directions of the fuel cell 1.

[0036] The front guard plate 3 is provided with bolt holes along the thickness direction thereof, which are used to fix the front guard plate 3 to the bottom surface of the battery compartment body 2 to achieve the front position limitation of the lower part of the fuel cell 1 .

[0037] The front and rear limit blocks 4 are installed on the front cavity wall of the battery compartment 2, and the mutually perpendicular adjacent sides of the front and rear limit blocks 4 are respectively attached to the side wall of the fuel cell 1 and the front cavity wall of the battery compartment 2, thereby achieving the limitation of the left side of the fuel cell 1.

[0038] The front and rear limit blocks 4 are provided with a plurality of bolt holes in a direction perpendicular to the front cavity wall of the battery compartment 2 , so as to fix the front and rear limit blocks 4 to the battery compartment 2 .

The auxiliary limit block 6 is installed on the front cavity wall of the battery compartment 2 and the outer wall is in contact with the side wall of the fuel cell 1. The auxiliary limit block 6 is provided with bolt holes in its length direction for fixing the auxiliary limit block 6. The auxiliary limit block 6 and the front and rear limit blocks 4 all contact the left wall of the fuel cell 1 and are used to limit the left side of the fuel cell 1. One difference between the two is that the heights are different, and they limit the upper and lower parts of the fuel cell 1 respectively.

[0040] The second aspect of the utility model provides a forklift, which has the above-mentioned auxiliary installation device for hydrogen fuel cells; the auxiliary installation device is installed on the front cavity wall in the battery compartment 2 of the forklift. During specific use, the fuel cell 1 is hoisted close to the battery compartment 2 of the forklift, and the rear wall and the right wall of the fuel cell 1 are respectively fitted with the rear cavity wall and the right cavity wall of the battery compartment 2 during hoisting, and the front guard plate 3 is placed between the fuel cell 1 and the front cavity wall of the battery compartment 2, and the front guard plate 3 and the front cavity wall of the battery compartment 2 are fitted, and then the front guard plate 3 is fixed to the bottom surface of the battery compartment 2 with bolts; one end of the first fixing plate 51 of the left and right limit blocks 5 is extended into the front cavity wall of the fuel cell 1 and the battery compartment 2, so that The first fixing plate 51 is fitted to the front cavity wall of the battery compartment 2, and the second fixing plate 52 is fitted to the right cavity wall of the battery compartment 2, and then the left and right limit blocks 5 are fixed to the upper front cavity wall of the battery compartment 2 with bolts; the front and rear limit blocks 4 are fitted to the left cavity wall of the battery compartment 2, and then the front and rear limit blocks 4 are fixed to the lower front cavity wall of the battery compartment 2 with bolts; the side wall of the auxiliary limit block 6 is fitted to the left cavity wall of the battery compartment 2, and then the auxiliary limit block 6 is fixed to the upper front cavity wall of the battery compartment 2 with bolts.
