It should be understood that different dependent claims and the features in this article can be combined in a manner different from that described in the original claims. It should also be understood that the features described in connection with a single embodiment can be used in other embodiments.

[0027] To solve the above problems, as Figures 1 to 3 shown, the present utility model provides a hydrogen storage device convenient for access, including a hydrogen storage cabinet 1 and a hydrogen storage tank assembly 2. The hydrogen storage tank assembly 2 is used for loading hydrogen storage tanks. An outlet 11 is provided on the side surface of the hydrogen storage cabinet 1. The hydrogen storage tank assembly 2 is arranged in the hydrogen storage cabinet 1 and is slidably connected to the hydrogen storage cabinet 1 to enter and exit the outlet 11. First clamping structures 3 are provided on both the left and right sides of the hydrogen storage tank assembly 2 along its sliding direction. Second clamping structures 4 are provided on the inner surfaces of both the left and right sides of the hydrogen storage cabinet 1. The first clamping structures 3 are detachably connected to the second clamping structures 4.

[0028] In this embodiment, an outlet 11 is provided on the side surface of the hydrogen storage cabinet 1. For example, the outlet 11 is provided on the side surface of the hydrogen storage cabinet 1 facing the positive direction of the Y-axis. A hydrogen storage tank assembly 2 is arranged to be slidably connected to the hydrogen storage cabinet 1. The hydrogen storage tank assembly 2 can be slidably connected to the hydrogen storage cabinet 1 along the Y-axis direction through the outlet 11. The hydrogen storage tank assembly 2 is loaded with hydrogen storage tanks. By pulling out or pushing in the hydrogen storage tank assembly 2 relative to the hydrogen storage cabinet 1, the access of the hydrogen storage tanks can be realized. On the left and right sides of the hydrogen storage tank assembly 2, that is, on both sides along the X-axis direction, first clamping structures 3 are provided. Correspondingly, on the inner surfaces of both sides of the hydrogen storage cabinet 1 along the X-axis direction, second clamping structures 4 are provided. The second clamping structures 4 are snap-connected to the first clamping structures 3. When the hydrogen storage tanks do not need to be taken, the hydrogen storage tank assembly 2 is pushed into the hydrogen storage cabinet 1, and the first clamping structure 3 is connected to the second clamping structure 4 to fix the hydrogen storage tank assembly 2 in the hydrogen storage cabinet 1, which is convenient for storing the hydrogen storage tanks and improves the safety of storing the hydrogen storage tanks. When the hydrogen storage tanks need to be taken, the second clamping structure 4 is disengaged from the snap connection with the first clamping structure 3, which is convenient for pulling out the hydrogen storage tank assembly 2 to take the hydrogen storage tanks.

[0029] Optionally, as Figures 1 to 3 shown, on the inner surfaces of both left and right sides of the hydrogen storage cabinet 1, brackets 13 extending in the front-back direction are provided. The first clamping structures 3 are lapped on the brackets 13 and are slidably connected to the brackets 13.

[0030] In this embodiment, by providing brackets 13 extending in the Y-axis direction on the inner surfaces of both sides of the hydrogen storage cabinet 1 along the X-axis direction, the extending direction of the brackets 13 is the same as the sliding direction of the hydrogen storage tank assembly 2. The first clamping structures 3 on both sides of the hydrogen storage tank assembly 2 are lapped on the brackets 13 on both sides of the hydrogen storage cabinet 1. The brackets 13 define the sliding direction for the hydrogen storage tank assembly 2, which is convenient for the hydrogen storage tank assembly 2 to be slidably connected to the hydrogen storage cabinet 1 along the Y-axis direction through the outlet 11.

[0031] Optionally, as Figure 3 and Figure 4 shown, the second clamping structure 4 includes a rotating seat 41, a rotating block 42 and a first spring 43. The rotating seat 41 is connected to the bracket 13. The rotating block 42 extends in the front-back direction, and the midpoint thereof is rotatably connected to the rotating seat 41. The rotating shaft extends horizontally and is perpendicular to the sliding direction of the hydrogen storage tank assembly 2. A clamping portion is provided on the lower surface of one end of the rotating block 42. The first clamping structure 3 is used for snap-connecting with the clamping portion. The lower surface of the other end of the rotating block 42 is connected to one end of the first spring 43. The first spring 43 extends in the vertical direction and the other end is connected to the bracket 13.

[0032] In this embodiment, by providing a rotating seat 41 at one end of the bracket 13 facing the negative direction of the Y-axis, the middle part of the rotating block 42 is rotatably connected to the rotating seat 41 and rotates around the X-axis. The height of the rotating seat 41 provides a rotating space for the rotating block 42. A fixing groove is formed on the lower surface of one end of the rotating block 42 facing the positive direction of the Y-axis. A first spring 43 is provided between one end of the rotating block 42 facing the negative direction of the Y-axis and the bracket 13. The first spring 43 extends along the Z-axis direction. When not in use, the rotating block 42 extends along the Y-axis direction. During the process of pushing the hydrogen storage tank assembly 2 into the hydrogen storage cabinet 1, the first clamping structure 3 is inserted between one end of the rotating block 42 facing the positive direction of the Y-axis and the bracket 13. The protrusion at the top of the first clamping structure 3 is embedded in the fixing groove. The elastic force of the first spring 43 on the rotating block 42 presses one end of the rotating block 42 facing the positive direction of the Y-axis against the first clamping structure 3, so that the first clamping structure 3 and the rotating block 42 are connected together, connecting the hydrogen storage tank assembly 2 and the hydrogen storage cabinet 1 together, and preventing the hydrogen storage tank assembly 2 from accidentally detaching from the hydrogen storage cabinet 1 due to jolting or the like.

[0033] Specifically, the rotating seat 41 includes support plates arranged side by side along the X-axis direction. A shaft hole extending along the X-axis direction is formed on the rotating plate. Rotating shafts are provided on both sides of the middle part of the rotating block 42 along the X-axis direction. The rotating block 42 is arranged between the two support plates, and the rotating shafts on both sides are respectively inserted into the shaft holes on both sides, realizing the braking connection between the rotating block 42 and the rotating seat 41.

[0034] Optionally, as Figure 4 shown, a pushing plate 44 extending upward is further provided at the midpoint of the rotating block 42. Push rods 51 extending along the front-back direction are further provided on both sides of the hydrogen storage tank assembly 2. The push rods 51 are slidably connected to the hydrogen storage tank assembly 2 along the front-back direction. One end of the push rod 51 away from the outlet 11 is used to push the pushing plate 44.

[0035] In this embodiment, by providing a pushing plate 44 extending vertically upward at the midpoint of the rotating block 42, the pushing plate 44 and the rotating block 42 can be integrally provided. A push rod 51 extending along the Y-axis direction is provided on the side surface of the hydrogen storage tank assembly 2 along the X-axis direction. The push rod 51 is slidably connected to the hydrogen storage tank assembly 2 along the Y-axis direction. The push rod 51 can slide along the Y-axis direction together with the hydrogen storage tank assembly 2. The pushing plate 44 is arranged on the moving path of the push rod 51. When the protrusion at the top of the first clamping structure 3 is embedded in the fixing groove, the push rod 51 does not contact the pushing plate 44. When the hydrogen storage tank needs to be taken out, manually push the pushing plate 44 to make the pushing plate 44 slide relative to the hydrogen storage tank assembly 2 in the negative direction of the Y-axis until the push rod 51 pushes the pushing plate 44, causing the rotating block 42 to rotate. One end of the rotating block 42 provided with the fixing groove first lifts up. At this time, the first clamping structure 3 and the rotating block 42 are separated, and the first clamping structure 3 can be drawn out together with the hydrogen storage tank assembly 2 in the positive direction of the Y-axis, facilitating the taking out of the hydrogen storage tank.

[0036] Specifically, fixing plates 21 are sleeved at both ends of the hydrogen storage tank, and openings are opened on the two fixing plates 21 for the push rod 51 to pass through, so as to facilitate the push rod 51 to be connected to the hydrogen storage tank assembly 2 and to achieve sliding relative to the hydrogen storage tank assembly 2 along the Y-axis direction.

[0037] Optionally, both ends of the push rod 51 exceed both ends of the hydrogen storage tank assembly 2 in the front-to-back direction, a limit baffle 52 is provided at the end of the push rod 51 away from the outlet 11, and a second spring 53 is sleeved around the side of the push rod 51, and both ends of the second spring 53 are respectively connected to the limit baffle 52 and the surface of the hydrogen storage tank assembly 2 away from the second clamping structure 4.

[0038] In this embodiment, by setting the length of the push rod 51 to exceed the length of the hydrogen storage tank assembly 2, both ends of the push rod 51 along the Y-axis direction exceed the two ends of the hydrogen storage tank assembly 2 along the Y-axis direction, so that it is convenient to manually contact the push rod 51, drive the push rod 51 to slide relative to the hydrogen storage tank assembly 2, and set a limit baffle 52 at one end of the push rod 51 facing the positive direction of the Y-axis, the diameter of the limit baffle 52 is larger than the diameter of the push rod 51, and a second spring 53 is sleeved on the part of the push rod 51 that exceeds the hydrogen storage tank assembly 2 in the positive direction of the Y-axis, and the two ends of the second spring 53 are respectively connected to the limit baffle 52 and the surface of one side of the hydrogen storage tank assembly 2 facing the positive direction of the Y-axis. When the hydrogen storage tank needs to be taken out, the push rod 51 is manually pressed, and the second spring 53 is compressed at this time. After the hydrogen storage tank assembly 2 is pulled out, let go, the second spring 53 returns to its original length, and the push rod 51 is reset, which is convenient for pushing the hydrogen storage tank assembly 2 in the next time.

[0039] Specifically, two ends of the second spring 53 are respectively connected to the limit baffle 52 and the fixed plate 21 facing the positive direction of the Y axis.

[0040] Alternatively, if Figure 4 As shown, the bracket 13 is also connected to a guide column 45 extending in the vertical direction, and the other end of the rotating block 42 is provided with a guide hole 46 penetrating in the vertical direction. The guide column 45 is inserted into the first spring 43 and the guide hole 46 .

[0041] In this embodiment, a guide column 45 is provided in the middle of the first spring 43 on the bracket 13. The guide column 45 extends along the Z-axis direction and is passed through the first spring 43. A guide hole 46 for avoiding the guide column 45 is provided on the end of the rotating block 42 facing the negative direction of the Y-axis. The end of the guide column 45 away from the bracket 13 can pass through the guide hole 46. The first spring 43 can be extended and retracted along the guide column 45. The guide column 45 specifies the extension and retraction direction of the first spring 43 to prevent the first spring 43 from being offset during the extension and retraction process.

[0042] Optionally, as shown in the figure, the hydrogen storage device facilitating access further includes a locking member. A first fixing hole is formed on the surface of the bracket 13, and a second fixing hole 31 penetrating in the vertical direction is formed on the first clamping structure 3. The locking member is used to pass through the first fixing hole and the second fixing hole 31.

[0043] In this embodiment, by forming a first fixing hole on the surface of the bracket 13 and a second fixing hole 31 corresponding to the first fixing hole on the first clamping structure 3, both the first fixing hole and the second fixing hole 31 extend along the Z-axis direction. When the hydrogen storage tank assembly 2 is pushed into the hydrogen storage cabinet 1, the first fixing hole and the second fixing hole 31 are just coaxially aligned. A locking member, for example, a pin shaft, is passed through the first fixing hole and the second fixing hole 31 to further fix the hydrogen storage tank assembly 2 to the bracket 13 and the hydrogen storage cabinet 1, preventing the hydrogen storage tank assembly 2 from moving randomly and improving the stability of the connection structure between the hydrogen storage tank assembly 2 and the hydrogen storage cabinet 1. When the hydrogen storage tank needs to be taken, the locking member is removed.

[0044] Specifically, the locking member can be a bolt. Correspondingly, both the first fixing hole and the second fixing hole 31 are threaded holes.

[0045] Optionally, as Figure 3 shown, first fixing holes are formed at both the front and rear ends of the bracket 13, and the first clamping structures 3 are provided at both the front and rear ends of the hydrogen storage tank assembly 2. The first clamping structure 3 on the side away from the outlet 11 is used for engaging connection with the second clamping structure 4. The second fixing holes 31 are formed on both of the first clamping structures 3, and a plurality of locking members are used to pass through the first fixing holes and the second fixing holes 31 located on both the front and rear sides of the hydrogen storage cabinet 1 respectively.

[0046] In this embodiment, by forming first fixing holes at both ends of the bracket 13 along the Y-axis direction, correspondingly, first clamping structures 3 are provided at both the front and rear ends of the sides of the hydrogen storage tanks along the X-axis direction. The first clamping structure 3 facing the negative Y-axis direction is detachably connected to the second clamping structure 4, and the first clamping structure 3 facing the positive Y-axis direction does not contact the second clamping structure 4. When the hydrogen storage tank assembly 2 is pushed into the hydrogen storage cabinet 1, the two first fixing holes on the hydrogen storage tank assembly 2 along the positive X-axis direction are respectively coaxially aligned with the two second fixing holes 31 on the bracket 13 in the positive X-axis direction. Similarly, the two first fixing holes on the hydrogen storage tank assembly 2 along the negative X-axis direction are respectively coaxially aligned with the two second fixing holes 31 on the bracket 13 in the negative X-axis direction. Four locking members are used to pass through four groups of first fixing holes and second fixing holes 31 to improve the stability of the connection structure between the hydrogen storage tank assembly 2 and the hydrogen storage cabinet 1.

[0047] Optionally, as Figure 1 shown, there are multiple groups of the hydrogen storage tank assemblies 2, and the multiple groups of the hydrogen storage tank assemblies 2 are arranged in sequence along the vertical direction in the hydrogen storage cabinet 1.

[0048] In this embodiment, by arranging multiple sets of hydrogen storage tank assemblies 2 along the Z-axis direction, the multiple sets of hydrogen storage tank assemblies 2 are all arranged in the hydrogen storage cabinet 1 and are slidably connected to the hydrogen storage cabinet 1, which is convenient for storing and taking out multiple hydrogen storage tanks at one time.

[0049] Optionally, as Figure 2 shown, a cabinet door 12 is provided at the outlet 11 of the hydrogen storage cabinet 1, and the cabinet door 12 is detachably connected to the hydrogen storage cabinet 1.

[0050] In this embodiment, by providing a cabinet door 12 on the surface of the outlet 11, the cabinet door 12 is rotatably and detachably connected to the hydrogen storage cabinet 1. For example, the cabinet door 12 is in interference fit with the outlet 11. When the hydrogen storage tank is not needed to be taken out, the cabinet door 12 is installed on the outlet 11 to protect the hydrogen storage tank assembly 2 and improve the safety of storing the hydrogen storage tank. When the hydrogen storage tank needs to be taken out, the cabinet door 12 is disassembled to facilitate taking out the hydrogen storage tank.

[0051] Specifically, an opening structure and a cooperating door structure are also provided on the side surface of the hydrogen storage cabinet 1 facing the negative Y-axis direction, which is convenient for installing the locking member facing the negative Y-axis direction.
