Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen batteries, and specifically relates to a hydrogen energy fuel cell with a self - protection function. Background Technique

[0002] A hydrogen fuel cell uses hydrogen as a chemical element to manufacture a battery for storing energy. Its basic principle is the reverse reaction of electrolyzing water. Hydrogen and oxygen are respectively supplied to the anode and the cathode. After hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released and reach the cathode through an external load. It is a green and environmentally friendly battery.

[0003] Existing hydrogen fuel cells do not have a dedicated protection structure and still use traditional packaging. During transportation and use, after being collided, it is easy to damage the internal structure of the battery, reducing the service life of the battery. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydrogen energy fuel cell with a self - protection function to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A hydrogen energy fuel cell with a self - protection function includes a hydrogen battery. A side plate is installed on each of the four end faces of the hydrogen battery. A buffer structure is installed at the center position of the surface of each side plate. An installation groove is opened at each of the left and right ends of the side plate, and an opening groove is opened at the lower end of the side plate. Two spring telescopic rods are symmetrically installed inside each of the installation groove and the opening groove. An extension plate is slidably connected inside the installation groove. Two adjacent extension plates are perpendicular to each other and contact to form a right - angle state. A support bottom plate is slidably connected inside the opening groove. One end of each of the support bottom plate and the extension plate is connected to the two spring telescopic rods.

[0006] Preferably, the buffer structure includes a groove, a communication groove, a fixing plate, a sleeve plate and a flipping plate. A groove is opened at the center position of the surface of the side plate. A communication groove is opened at the position of the side - plate surface on both the left and right sides of the groove. A fixing plate is fixedly installed inside the groove. An outer end of the fixing plate is sleeved and connected with a sleeve plate through a spring telescopic rod. Flipping plates are rotatably connected to both the left and right ends of the sleeve plate. The size of the flipping plate is adapted to the size of the communication groove.

[0007] Preferably, the sleeve plate is connected to the flipping plate through a rotating shaft, and a torsion spring is arranged inside the rotating shaft.

[0008] Preferably, the width dimension of the groove is greater than the sum of the width dimensions of the sleeve plate and the two flipping plates, and the sleeve plate extends to the outside of the side plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] As Figures 1 to 5 shown, the hydrogen energy fuel cell with self - protection function in this embodiment includes a hydrogen cell 1. A side plate 2 is installed on each of the four end faces of the hydrogen cell 1. The length dimensions of the four side plates 2 need to be adjusted according to the size of the hydrogen cell 1. The materials of the four side plates 2 are the same, but the sizes are not exactly the same. A buffer structure 3 is installed at the center position of the surface of each side plate 2. An installation groove 7 is opened at both the left and right ends of the side plate 2. The installation groove 7 does not contact the buffer structure 3. An opening groove 9 is opened at the lower end of the side plate 2. Two spring telescopic rods 8 are symmetrically installed inside both the installation groove 7 and the opening groove 9. An extension plate 4 is slidably connected inside the installation groove 7. Two adjacent extension plates 4 are perpendicular to each other and contact to form a right - angle state. In the normal state, the two extension plates 4 will be ejected by the spring telescopic rods 8 and then contact each other to form a complete right - angle state. When being impacted, the extension plates 4 will contract into the inside of the installation groove 7, and the spring telescopic rods 8 will play a certain buffering role to prevent the hydrogen cell 1 from directly contacting the external environment. A support bottom plate 5 is slidably connected inside the opening groove 9. One end of both the support bottom plate 5 and the extension plate 4 is connected to the two spring telescopic rods 8. The connection relationship between the support bottom plate 5 and the opening groove 9 is similar to that of the extension plate 4 and can also play a certain buffering role.

[0022] Specifically, the buffer structure 3 includes a groove 301, a communication groove 302, a fixing plate 303, a sleeve plate 304 and a flipping plate 305. A groove 301 is provided at the center of the surface of the side plate 2. A communication groove 302 is provided at each of the positions on the surface of the side plate 2 on the left and right sides of the groove 301. A fixing plate 303 is fixedly installed inside the groove 301. The outer end of the fixing plate 303 is sleeved and connected with a sleeve plate 304 through a spring telescopic rod 8. Flipping plates 305 are rotatably connected to both the left and right ends of the sleeve plate 304. The size of the flipping plate 305 is adapted to the size of the communication groove 302. The sleeve plate 304 is connected to the flipping plate 305 through a rotating shaft. A torsion spring is provided inside the rotating shaft. In the normal state, the torsion spring will drive the rotating shaft and the flipping plate 305 to be inside the communication groove 302. The width dimension of the groove 301 is greater than the sum of the width dimensions of the sleeve plate 304 and the two flipping plates 305. The sleeve plate 304 extends to the outside of the side plate 2. When the side of the hydrogen battery 1 is impacted, the sleeve plate 304 extending outside the side plate 2 will cause the sleeve plate 304 to be impacted first. At this time, the sleeve plate 304 will slide into the groove 301. Since the sleeve plate 304 is rotatably connected to the flipping plate 305, after the sleeve plate 304 enters the groove 301, the flipping plate 305 will be squeezed by the inner wall of the groove 301 and thus flip outwards. At this time, an external collision object will apply an inward force to the sleeve plate 304, and the two flipping plates 305 will apply an outward force to the external collision object. The directions of the two forces are opposite, which will form a certain cancellation, thereby playing a buffering role.

[0023] Furthermore, a synchronizing rod 6 is installed between two adjacent supporting bottom plates 5. The four supporting bottom plates 5 can be connected through the four synchronizing rods 6, so that the four supporting bottom plates 5 form a synchronous whole. The connection relationship between the four supporting bottom plates 5 and the four synchronizing rods 6 is detachable. When one supporting bottom plate 5 is impacted, it will drive the other three supporting bottom plates 5 to displace in the same direction, and thus share the force received to the other three supporting bottom plates 5, which can play a buffering effect to a certain extent.

[0024] Even further, a card slot 10 is provided on each of the four end surfaces of the hydrogen battery 1. A card block 11 is installed at each end of the side plate 2 away from the buffer structure 3. The card slot 10 is adapted to the card block 11. The hydrogen battery 1 and the side plate 2 are connected by the way of clamping the card slot 10 and the card block 11, which can facilitate the user to disassemble and install.

[0025] The usage method of this embodiment is as follows: A side plate 2 is clamped on each of the four end faces of the hydrogen battery 1. A buffer structure 3 is installed at one outer end of the side plate 2. The lower end of the side plate 2 is connected to a support bottom plate 5 through a spring telescopic rod 8. The left and right ends of the side plate 2 are both connected to an extension plate 4 through a spring telescopic rod 8. Two adjacent extension plates 4 contact each other and form a right angle. The four corners of the hydrogen battery 1 can be protected by the extension plates 4. The buffer structure 3 on the outer surface of the side plate 2 can protect the four end faces of the hydrogen battery 1. The four support bottom plates 5 at the lower ends of the four side plates 2 can protect the lower end of the hydrogen battery 1. Thus, a relatively comprehensive protection effect can be provided for the hydrogen battery 1.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
