All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] A hydrogen generator protective cover, as Figure 1 shown, includes a protective shell 1. A chute 2 is opened at the inner bottom end of the protective shell 1. A through groove 3 is opened at the top end of the protective shell 1. And a protective mechanism 4 is movably connected inside the through groove 3. A plurality of universal wheels 5 are fixedly connected to the bottom end of the protective shell 1. A handle 6 is fixedly hinged to the rear side of the protective shell 1. And an auxiliary mechanism 7 is fixedly connected to the side of the protective shell 1 away from the handle 6. A box door 8 is movably connected to the front side of the protective shell 1. An installation shell 10 is fixedly connected to the top end of the protective shell.

[0023] During use, first, after the operator places the hydrogen generator inside the protective shell 1, the operator can control the rotation of the first motor 401. When the first motor 401 rotates, it drives the rotation of the cam 402, and then the cam 402 drives the two protective plates 404 on both sides to approach each other. At this time, the protective plates 404 will drive the protective pads 9 to clamp and fix both sides of the hydrogen generator. The slider 405 and the slide rail 406 can make the movement of the protective plate 404 more stable during movement. The protective plates 404 and the protective pads 9 can prevent the hydrogen generator from colliding inside the protective shell 1 during the transfer process by the operator, thereby avoiding damage or wear of the hydrogen generator. When the operator needs to take out the hydrogen generator for maintenance, the operator can control the second motor 701 to drive the rotation of the screw rod 703. When the screw rod 703 rotates, it will drive the two movable blocks 704 on both sides to move away from each other. At this time, the transmission rod 705 will drive the push plate 706 to move back and forth, so as to push out a part of the hydrogen generator from inside the protective shell 1, making it more convenient for the operator to take. In addition, after the operator closes the box door 8 during transfer, the operator can also control the push plate 706 to slightly push a part of the hydrogen generator, so as to clamp and fix the hydrogen generator in the front and back directions by the box door 8 and the push plate 706, improving the stability during transfer.

[0024] As Figures 3-4 As shown in the figure, the protection mechanism 4 includes a first motor 401, a cam 402, a connecting rod 403, a protective plate 404, a slider 405 and a slide rail 406. The output end of the first motor 401 is fixedly connected to the axis of the cam 402. There are two symmetrically arranged connecting rods 403 on the left and right, and one end of each connecting rod 403 is movably connected to the bottom end of the cam 402 through a bearing, and the other end of the connecting rod 403 is hinged to the top end of the protective plate 404. The slider 405 is slidably connected to the top end of the slide rail 406, and the top end of the slider 405 is fixedly connected to the bottom end of the protective plate 404. The slide rail 406 is fixedly connected to the inside of the chute 2. The top end of the protective plate 404 is slidably connected to the inside of the through groove 3. The bottom end of the protective plate 404 is movably connected to the inside of the protective shell 1. The cam 402 is rotatably connected to the inside of the mounting shell 10. The fixed end of the first motor 401 is fixedly connected to the inner top end of the mounting shell 10. There are two symmetrically arranged groups of slide rails 406. The outer wall of the protective plate 404 is fixedly connected with a protective pad 9.

[0025] After the operator places the hydrogen generator inside the protective shell 1, the operator can control the rotation of the first motor 401. When the first motor 401 rotates, it drives the rotation of the cam 402, and then the cam 402 drives the two protective plates 404 on both sides to approach each other. At this time, the protective plates 404 will drive the protective pads 9 to clamp and fix both sides of the hydrogen generator. The slider 405 and the slide rail 406 can make the movement of the protective plate 404 more stable during movement. The protective plates 404 and the protective pads 9 can prevent the hydrogen generator from colliding inside the protective shell 1 during the transfer process by the operator, thereby avoiding damage or wear of the hydrogen generator.

[0026] As shown Figures 2-3 in FIG. Figures 2-3 , the auxiliary mechanism 7 includes a second motor 701, a fixed housing 702, a screw rod 703, a movable block 704, a transmission rod 705, and a push plate 706. The output end of the second motor 701 is fixedly connected to one end of the screw rod 703. There are two symmetrically arranged movable blocks 704 on the left and right, and the movable block 704 is threadedly connected to the outer wall of the screw rod 703. One end of the transmission rod 705 is hinged to the outer wall of the movable block 704, and the other end of the transmission rod 705 is hinged to the outer wall of the push plate 706. The second motor 701 is fixedly connected to the outer wall of the protective housing 1. The screw rod 703 is rotatably connected to the inside of the fixed housing 702. The movable block 704 is movably connected to the inside of the fixed housing 702. One side of the push plate 706 is movably connected to the inside of the protective housing 1.

[0027] When personnel need to take out the hydrogen generator for maintenance, they can control the second motor 701 to drive the screw rod 703 to rotate. When the screw rod 703 rotates, it will drive the two movable blocks 704 on both sides to move away from each other. At this time, the transmission rod 705 will drive the push plate 706 to move back and forth, so as to push out a part of the hydrogen generator from the inside of the protective housing 1, making it more convenient for personnel to take. In addition, when transferring, after personnel close the box door 8, they can also control the push plate 706 to slightly push a part of the hydrogen generator, so as to clamp and fix the hydrogen generator in the front and back directions through the box door 8 and the push plate 706, improving the stability during transfer.

[0028] The working principle is as follows:

[0029] After personnel place the hydrogen generator inside the protective housing 1, they can control the first motor 401 to rotate. When the first motor 401 rotates, it drives the cam 402 to rotate, and then the cam 402 drives the two protective plates 404 to approach each other. At this time, the protective plates 404 will drive the protective pads 9 to clamp and fix both sides of the hydrogen generator. When personnel need to take out the hydrogen generator for maintenance, they can control the second motor 701 to drive the screw rod 703 to rotate. When the screw rod 703 rotates, it will drive the two movable blocks 704 on both sides to move away from each other. At this time, the transmission rod 705 will drive the push plate 706 to move back and forth, so as to push out a part of the hydrogen generator from the inside of the protective housing 1, making it more convenient for personnel to take. In addition, when transferring, after personnel close the box door 8, they can also control the push plate 706 to slightly push a part of the hydrogen generator, so as to clamp and fix the hydrogen generator in the front and back directions through the box door 8 and the push plate 706.
