[0002] A fuel cell-based mobile charging device is a device that uses hydrogen fuel cell technology to provide fast charging services for electric vehicles.

[0003] Utility model announcement CN208515405U discloses a charging device for hydrogen fuel cell vehicles. The key technical features include: a base with a charging pile mounted on its top; a NUC controller and a control panel on one side of the charging pile, with the NUC controller located below the control panel; a sliding sleeve slidably connected to the outer side of the charging pile via a sliding groove; fixing blocks on both sides of the sliding sleeve; and a ring-shaped frame on one side of each fixing block. The device also features a magnetic ring on the outer side of the canopy. When it rains, the user can pull down the outer cover attached to the magnetic ring, allowing the bottom of the cover to slide below the rain cover, thus extending the rain cover. When the weather is clear, the user can slide the outer cover upwards, allowing it to reattach to the outer side of the magnetic ring. This solves the problem of the charging device's rain cover being difficult to adjust according to the weather, affecting the safety of the charging device.

[0004] Regarding the above-mentioned issues, the following technical defects have been found: In the case of existing charging devices, the heat dissipation holes cannot be sealed or opened according to the operating intensity of the equipment, which reduces the environmental adaptability of the charging device.

[0005] Therefore, it is necessary to provide a new type of mobile charging device based on fuel cells to solve the above-mentioned technical problems. Utility Model Content

[0016] The effect achieved by the above components is that, by setting up protective components, the protective plate can be automatically adjusted to cover and protect components such as charging guns in rainy or snowy weather, thereby minimizing the risk of components getting wet from rain and increasing the oxidation rate.

[0018] The effect achieved by the above components is as follows: during the rotation of the connecting plate along the inner wall of the fixed base, the slide rod fixed on the connecting plate will slide along the inner wall of the arc-shaped hole, thereby limiting the rotation process of the connecting plate, improving the stability of the moving process of the connecting plate, and limiting the rotation angle of the connecting plate and the protective plate to prevent the protective plate from colliding with the casing due to excessive rotation angle.

[0019] Preferably, the protective plate is an aluminum alloy plate.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 and Figure 2 This utility model provides a mobile charging device based on a fuel cell, comprising: a housing 1, a charging gun 5, and two adjustment components 3. The charging gun 5 is electrically connected to the housing 1 via a wire. A control panel 6 is installed on one side of the housing 1. Several casters 2 are installed on the lower surface of the housing 1. Several heat dissipation holes 7 are provided on both sides of the housing 1. The adjustment components 3 are located on the side of the housing 1 near the heat dissipation holes 7. A protective component 4 is provided on the upper surface of the housing 1.

[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 4The adjustment component 3 includes a connecting frame 301 with a rectangular cross-section. One side of the connecting frame 301 is attached to the housing 1. Several sealing plates 302 are fixedly connected to the inner wall of the connecting frame 301. The sealing plates 302 are adapted to the size of the heat dissipation holes 7. A partition plate 304 is fixedly connected to one side of the outer wall of the connecting frame 301. A lead screw 305 is threaded through the side of the partition plate 304. One side of the sealing plate 302 is attached to the housing 1. By setting the adjustment component 3, during the daily use of the charging device, the heat dissipation holes 7 can be sealed or opened according to the weather conditions or the operating intensity of the charging device by adjusting the sealing plates 302. The heat dissipation holes 7 can be fully opened to enhance heat dissipation at high temperatures and partially closed at low temperatures to reduce the impact of cold air on the components. A welding plate 306 is fixedly connected to the side of the housing 1 near the heat dissipation holes 7. A servo motor 307 is fixedly connected to one side of the welding plate 306. The output end of the servo motor 307 is fixedly connected to one end of the lead screw 305. Starting the servo motor 307 drives the lead screw 305 to rotate, achieving automatic control of the lead screw 305's rotation. Several positioning plates 309 are fixedly connected to the outer wall of the housing 1 near the heat dissipation hole 7. One end of the positioning rod 310 is fixedly connected to the outer wall of the connecting frame 301 away from the partition 304. The positioning rod 310 has a rectangular cross-section. When the lead screw 305 rotates, driving the partition 304 and connecting frame 301 to move, the positioning plates 309 fixed to the connecting frame 301 will move through the positioning plates 309, thereby improving the stability of the connecting frame 301 driving the sealing plate 302 to move. A filter frame 308 is fixedly connected to the inner wall of the connecting frame 301, and a filter screen 303 is fixedly connected to the inner wall of the filter frame 308. The filter screen 303 can filter dust and other dirt from the outside of the housing 1, preventing dust and other dirt from entering the housing 1 through the heat dissipation hole 7.

[0035] In the embodiments of this utility model, please refer to Figure 5 and Figure 6The protective component 4 includes a fixed base 41, the lower surface of which is fixedly connected to the upper surface of the housing 1. A connecting plate 42 is rotatably connected to the inner wall of the fixed base 41. A protective plate 44 is fixedly connected to one side of the connecting plate 42. The protective plate 44 is bent. A drive motor 43 is fixedly connected to one side of the fixed base 41. The output end of the drive motor 43 is fixedly connected to the connecting plate 42. By setting the protective component 4, the protective plate 44 can be automatically adjusted to cover and protect components such as the charging gun 5 in rainy or snowy weather, thereby minimizing the risk of components getting wet from rain and increasing oxidation. An arc-shaped hole 45 is provided on the side of the fixed base 41 away from the drive motor 43. The center of the arc-shaped hole 45 is coaxial with the axis of rotation of the connecting plate 42. A sliding rod 46 is slidably connected to the inner wall of the arc-shaped hole 45. One end of the sliding rod 46 is fixedly connected to one side of the connecting plate 42. As the connecting plate 42 rotates along the inner wall of the fixed base 41, the sliding rod 46 fixed on the connecting plate 42 slides along the inner wall of the arc-shaped hole 45, thereby limiting the rotation of the connecting plate 42, improving the stability of the connecting plate 42's movement, and limiting the rotation angle of the connecting plate 42 and the protective plate 44, preventing the protective plate 44 from colliding with the housing 1 due to excessive rotation angle. The protective plate 44 is specifically made of aluminum alloy. By making the protective plate 44 of aluminum alloy, the protective plate 44 has high strength and light weight, effectively improving the protective strength of the protective plate 44.

[0036] The working principle of the mobile charging device based on a fuel cell provided by this utility model is as follows: When it is necessary to open the sealing plate 302, the servo motor 307 is first started to drive the lead screw 305 to rotate. The lead screw 305 drives the partition 304 to move. The partition 304 drives the connecting frame 301, which in turn drives the sealing plate 302, causing the sealing plate 302 to separate from the heat dissipation hole 7, thus completing the opening of the sealing plate 302. When it is necessary to seal the heat dissipation hole 7 with the sealing plate 302, the servo motor 307 is first started to drive the lead screw 305 to rotate in the opposite direction. The lead screw 305 drives the partition 304 in the opposite direction. The partition 304 moves, driving the connecting frame 301, which in turn drives the sealing plate 302. Once the sealing plate 302 blocks the heat dissipation hole 7, the heat dissipation hole 7 is sealed. When the lead screw 305 rotates to drive the partition 304 and the connecting frame 301 to move, the positioning plate 309 fixed on the connecting frame 301 will move through the positioning plate 309, thereby improving the stability of the process of the connecting frame 301 driving the sealing plate 302 to move. In addition, the filter screen 303 can filter dust and other dirt from the outside of the housing 1, preventing dust and other dirt from entering the inside of the housing 1 through the heat dissipation hole 7.

[0037] When the protective plate 44 needs adjustment during rainy or snowy weather, first start the drive motor 43 to drive the connecting plate 42, causing the connecting plate 42 to rotate along the inner wall of the fixed base 41. The connecting plate 42 then drives the protective plate 44, allowing the protective plate 44 to rotate. Once the protective plate 44 has rotated to the appropriate position, stop the drive motor 43. At this time, the protective plate 44 can cover and protect components such as the charging gun 5 as much as possible, minimizing the risk of components getting wet from rain and increasing oxidation. When the protective plate 44 is no longer needed to protect the charging device, start the drive motor 43 to drive the connecting plate 42 to rotate in the opposite direction, and the connecting plate 42 will drive the protective plate 44 to rotate in the opposite direction. The movement continues until the protective plate 44 returns to its original position. During the rotation of the connecting plate 42 along the inner wall of the fixed base 41, the slide rod 46 fixed on the connecting plate 42 slides along the inner wall of the arc-shaped hole 45, thereby limiting the rotation process of the connecting plate 42, improving the stability of the moving process of the connecting plate 42, and limiting the rotation angle of the connecting plate 42 and the protective plate 44 to prevent the protective plate 44 from colliding with the housing 1 due to excessive rotation angle. In addition, by making the protective plate 44 with aluminum alloy material, the protective plate 44 has high strength and light weight, effectively improving the protective strength of the protective plate 44.
