[0009] As a preferred technical solution of the present invention, two groups of lateral extrusion springs and sleeves are provided, and are symmetrically distributed on both sides of the sliding storage block.

[0010] As an optimal technical solution of the present invention, the protective shell also includes a slide groove, a card groove, and a limiting slide rail. The slide groove is opened at the inner side end of the protective shell, the card groove is opened at the inner end of the slide groove, and the limiting slide rail is opened at the other side end surface inside the protective shell.

[0011] As a preferred technical solution of the present invention, a columnar groove is provided inside the protective cover, and another group of small-sized columnar grooves is provided in the middle of the columnar groove.

[0012] As a preferred technical solution of the present invention, a columnar groove structure having a size larger than that of the hydrogen battery is provided on the top of the sliding storage block.

[0013] As a preferred technical solution of the present invention, there is a sliding connection between the limiting sliding block and the limiting sliding rail.

[0014] As a preferred technical solution of the present invention, the sleeve column is in a sliding connection with the slide groove, and the lateral extrusion spring is always in a contracted state when the sleeve column is in the slide groove.

[0015] Compared with the prior art, the present invention provides a hydrogen fuel cell protection device with the following beneficial effects:

[0016] The hydrogen fuel cell protection device is provided with a spring pad, a sliding storage block, a slide groove and a card slot. When the hydrogen battery is placed in the device, the operator first rotates the protective cover open through the hinge connection, and then inserts the bottom of the hydrogen battery into the protective shell, and squeezes the sliding storage block downward after the bottom end of the hydrogen battery contacts the sliding storage block. After the sliding storage block is squeezed, the lateral extrusion spring also slides downward, and continuously applies pressure to the bottom extrusion spring, causing the bottom extrusion spring to contract until the lateral extrusion spring and the sleeve slide to the card slot position in the slide groove. When the sleeve is in the card slot position, the lateral extrusion spring in a tightened state releases pressure to the side, causing the sleeve to The hydrogen battery is fully protected by the protective shell and the protective cover. When the hydrogen battery needs to be removed, the operator only needs to open the protective cover, then pinch the protruding sleeves on both sides of the protective shell with his fingers, and apply pressure to compress the sleeves back into the protective shell. At this time, there is no object stuck on both sides of the sliding storage block, and the bottom extrusion spring releases pressure and rebounds, causing the sliding storage block to slide upward along the limit rail until it reaches the end of the limit rail. At this time, the hydrogen battery is ejected from the protective shell and the operator can take it out directly.

[0017] Through the above process, the device can achieve the following beneficial effects:

[0018] By arranging the spring pad, when the protective cover is in the closed state, if the hydrogen battery inside the protective shell is displaced, the top of the hydrogen battery can be buffered under the pressure of the spring pad. By arranging the sliding storage block, the slide groove and the card slot, when the hydrogen battery is placed inside the protective shell, it can be stored by the sliding storage block. With the cooperation of the lateral extrusion spring and the bottom extrusion spring, the sliding storage block can be quickly ejected by pressing the sleeve column, so that the device can not only simply provide all-round protection for the hydrogen battery, but also can be quickly taken out when the hydrogen battery needs to be taken out. The structure is simple, and the storage and use of the hydrogen battery are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Specifically, by providing two sets of lateral extrusion springs 601 symmetrically distributed at both ends of the sliding storage block 6, both ends of the sliding storage block 6 can be subjected to uniform and stable pressure;

[0030] In this embodiment, a columnar groove is further provided inside the protective cover 3, and another set of small columnar grooves is provided in the middle of the columnar groove. A columnar groove structure larger than the hydrogen battery 2 is provided on the top of the sliding storage block 6.

[0031] Specifically, the columnar groove opened inside the protective cover 3 can better support the placement of the hydrogen battery 2, and its groove-shaped structure can better fit the top structure of the hydrogen battery 2;

[0032] In this embodiment, there is a sliding connection between the limiting slider 603 and the limiting slide rail 103; there is a sliding connection between the sleeve 602 and the slide groove 101, and when the sleeve 602 is inside the slide groove 101, the lateral extrusion spring 601 is always in a contracted state.
