[0045] The gas cylinder compartment 20 according to the embodiment of the present application will be described in detail below with reference to the drawings.

[0046] As shown in Figure 1 and Figure 2 The gas cylinder compartment 20 according to the embodiment of the present application includes a compartment bottom 21, a compartment cover 22 and a hydrogen storage device 25.

[0047] Specifically, the cover 22 is arranged on the bottom 21, and the cover 22 and the bottom 21 cooperatively define a containing cavity 23, and a supporting plate 24 with an integrated card reader is arranged at the bottom of the containing cavity 23. A hydrogen storage device 25 is arranged in the containing cavity 23, and the hydrogen storage device 25 comprises a bottle head 251 and a bottle bottom 253, and an electronic chip for storing information of the hydrogen storage device 25 is arranged on the bottle bottom 253. When the hydrogen storage device 25 is placed in the containing cavity 23, the bottle head 251 of the hydrogen storage device 25 is adapted to face the door 13 of the hydrogen exchange cabinet 100, so as to facilitate taking the hydrogen storage device 25, and the bottle bottom 253 of the hydrogen storage device 25 faces the supporting plate 24, and the card reader is signal connected with the electronic chip, so as to read the information of the hydrogen storage device 25.

[0048] In other words, the gas cylinder bin 20 according to the embodiment of the utility model mainly comprises a bottom 21, a cover 22 and a hydrogen storage device 25. As shown in Figures 1 to 3 , the cover 22 is mounted on the bottom 21, and the cover 22 and the bottom 21 can be fixedly mounted through a plurality of mounting holes by screws. The cover 22 and the bottom 21 can cooperatively define a containing cavity 23 for placing the hydrogen storage device 25, and a supporting plate 24 with an integrated card reader is arranged at the bottom of the containing cavity 23, and the card reader has a card reading / writing function. As shown in Figure 1 and Figure 2 , the hydrogen storage device 25 can be placed in the containing cavity 23, and the hydrogen storage device 25 comprises a bottle head 251 and a bottle bottom 253 (see Figure 1 ). The bottle head 251 is provided with a valve 252, and the bottle bottom 253 is provided with an electronic chip for storing information of the hydrogen storage device 25. The electronic chip stores information related to the hydrogen storage device 25, such as hydrogen filling times, cycle times, hydrogen content ratio, hydrogen bottle mass, etc. The card reader can read the information in the electronic chip only by identifying the electronic chip at a close distance.

[0049] When the hydrogen storage device 25 is placed in the containing cavity 23, as shown in Figure 1 and Figure 7As shown, the bottle head 251 of the hydrogen storage device 25 is suitable for facing the cabinet door 13 of the hydrogen exchange cabinet 100, so as to facilitate taking the hydrogen storage device 25, and when the hydrogen storage device 25 is placed in the gas cylinder bin 20 in a manner that the bottle head 251 faces outward and the bottle bottom 253 faces inward, the electronic chip of the bottle bottom 253 will be close to or in contact with the supporting plate 24 in the gas cylinder bin 20. The bottle head 251 faces outward and the bottle bottom 253 faces inward, which facilitates the user to take out the hydrogen cylinder from the cabinet, and only needs to pinch the bottle head of the hydrogen storage device 25 with a relatively small diameter. And the bottle head 251 faces outward and the bottle bottom 253 faces inward, which does not affect the service life of the lead wire during the opening and closing of the cabinet door 13. If the bottle bottom 253 faces outward and the bottle head faces inward, the user will not be easy to take out when taking the hydrogen storage device 25. The bottle bottom 253 of the hydrogen storage device 25 faces the supporting plate 24, and the card reader is signal connected with the electronic chip to read the information of the hydrogen storage device 25, so as to send the data to the background storage.

[0050] Therefore, according to the gas cylinder bin 20 and the hydrogen storage device 25 of the embodiment of the present application, the hydrogen storage device 25 is placed in a manner that the bottle head 251 faces outward and the bottle bottom 253 faces inward, which facilitates taking the hydrogen storage device 25. And the bottle head 251 faces outward and the bottle bottom 253 faces inward, which does not affect the service life of the lead wire during the opening and closing of the cabinet door 13. At the same time, the supporting plate 24 with the integrated card reader is arranged in the gas cylinder bin 20, the bottle bottom 253 of the hydrogen storage device 25 is provided with an electronic chip, and the card reader is signal connected with the electronic chip, so as to read the related information of the hydrogen storage device 25, send the data to the background storage, and facilitate the background to independently judge whether the hydrogen amount in the hydrogen storage device 25 is sufficient, so as to correspondingly pop up the cabinet door 13 with sufficient hydrogen amount, facilitate the user to take out the corresponding hydrogen storage device 25, and the actual use is very convenient.

[0051] According to an embodiment of the present application, the supporting plate 24 is a hollow structure plate, and one side of the supporting plate 24 facing the bin bottom 21 is provided with a protruding fixing part for connecting the supporting plate 24 and the bin bottom 21.

[0052] That is, as shown in the drawings, Figure 3 That is, as shown in the drawings,

[0053] According to an embodiment of the present application, one side of the supporting plate 24 facing the accommodating cavity 23 is provided with a buffer plate 26, and the buffer plate 26 is formed in a circular or semicircular shape corresponding to the cross-sectional shape of the accommodating cavity 23.

[0054] That is, as shown in the drawings, Figure 3A buffer plate 26 is provided on the side of the support plate 24 facing the receiving cavity 23. The buffer plate 26 can be set into a circle or a semi-circle corresponding to the cross-sectional shape of the receiving cavity 23. The buffer plate 26 is made of soft material to prevent the bottom of the bottle 253 from directly colliding with the support plate 24 when the user puts the hydrogen storage device 25 in with excessive force, which could damage the electronic chip or the support plate 24.

[0055] According to one embodiment of the present invention, the inner wall of the bottom 21 is formed in an arc shape corresponding to the shape of the hydrogen storage device 25. A weighing contact plate 27 is provided on the inner wall of the bottom 21. The weighing contact plate 27 is located near the bottle head 251 of the hydrogen storage device 25. A weighing module 28 is provided on the outer wall of the bottom 21 to weigh the hydrogen storage device 25.

[0056] In other words, such as Figures 1 to 3 As shown, the inner wall of the bottom 21 is designed in an arc shape corresponding to the shape of the hydrogen storage device 25, ensuring that the bottom surface of the gas cylinder compartment 20 is an arc surface that matches the arc of the surface of the hydrogen storage device 25, facilitating the placement of the hydrogen storage device 25. Figure 3 As shown, a weighing contact plate 27 is installed on the inner wall of the bottom 21 of the storage compartment. The arc surface of the weighing contact plate 27 is consistent with the arc of the inner bottom surface of the gas cylinder compartment 20. When the hydrogen storage device is not placed inside, the weighing contact plate 27 protrudes slightly from the inner bottom surface of the gas cylinder compartment 20. The weighing contact plate 27 is located near the cylinder head 251 of the hydrogen storage device 25. A weighing module 28 is installed on the outer wall of the bottom 21 of the storage compartment to weigh the hydrogen storage device 25. Specifically, the weighing module 28 is located at the bottom of the gas cylinder compartment 20, corresponding to the weighing contact plate 27. After the hydrogen storage device 25 is placed into the gas cylinder compartment 20, it comes into contact with the weighing contact plate 27. The weighing contact plate 27 is connected to the weighing module 28, which can weigh the hydrogen storage device 25 to obtain its current mass data. The combination of the card reader and the weighing module 28 can be used to accurately determine whether the user has successfully borrowed or returned the cylinder.

[0057] In summary, according to the embodiment of this utility model, the hydrogen storage device 25 in the gas cylinder compartment 20 is placed with the bottle head 251 facing outwards and the bottle bottom 253 facing inwards, which facilitates the retrieval of the hydrogen storage device 25. Furthermore, this placement method ensures that the lifespan of the lead wire is not affected during the opening and closing of the cabinet door 13. The gas cylinder compartment 20 is equipped with a support plate 24 integrating a card reader, and the bottom 253 of the hydrogen storage device 25 is equipped with an electronic chip. By connecting the card reader to the electronic chip, information about the hydrogen storage device 25 can be read and sent to the backend storage. This allows the backend to automatically determine whether the amount of hydrogen in the hydrogen storage device 25 is sufficient, and accordingly, the cabinet door 13 will open when the amount of hydrogen is sufficient, allowing the user to easily retrieve the corresponding hydrogen storage device 25. This makes it very convenient to use.

[0058] Of course, other structures of the gas cylinder bin 20 and its working principle can be understood and realized by those skilled in the art, and will not be described in detail in the utility model.

[0059] According to the second aspect of the utility model, as shown in Figures 4 to 10 , a hydrogen exchange cabinet 100 is provided, comprising a cabinet body 11, a cabinet plate 12 and a cabinet door 13.

[0060] Specifically, the cabinet plate 12 is arranged in the cabinet body 11 and is distributed layer by layer in the cabinet body 11, and each cabinet plate 12 is used for placing the gas cylinder bin 20 in the above-mentioned embodiments. The bottom column 29 protruding towards the cabinet plate 12 is arranged on the bin bottom 21 in the gas cylinder bin 20, so as to fix the gas cylinder bin 20 on the cabinet plate 12. The side of the cabinet door 13 facing the cabinet plate 12 is provided with a top plate 14, and the top plate 14 is used for limiting the bottle head 251 of the hydrogen storage device 25 in the gas cylinder bin 20 to face the top plate 14.

[0061] In other words, as shown in Figure 4 and Figures 8 to 10 , the hydrogen exchange cabinet 100 according to the utility model embodiment mainly comprises a cabinet body 11, a cabinet plate 12 and a cabinet door 13. As shown in Figure 11 , the cabinet plate 12 is arranged in the cabinet body 11, and the cabinet plate 12 is distributed layer by layer in the cabinet body 11, so that the cabinet plate 12 is formed from top to bottom in the cabinet body 11, and the two sides and the front side of the cabinet plate 12 are fixedly connected with the cabinet body 11. Each cabinet plate 12 is used for placing the gas cylinder bin 20 in the above-mentioned embodiments. The bottom column 29 protruding towards the cabinet plate 12 is arranged on the bin bottom 21 in the gas cylinder bin 20, and the bottom column 29 is provided with an internal thread. After the screw passes through the cabinet plate 12, the screw is screwed into the internal thread of the bottom column 29, so as to fix the cabinet plate 12 and the gas cylinder bin 20. The side of the cabinet door 13 facing the cabinet plate 12 is provided with a top plate 14, and the top plate 14 is used for limiting the bottle head 251 of the hydrogen storage device 25 in the gas cylinder bin 20 to face the top plate 14, so as to ensure that the valve 252 of the bottle head 251 can be inserted into the groove of the top plate 14.

[0062] As shown in Figure 12 and Figure 10 , when the cabinet door 13 is closed, the top plate 14 does not contact the hydrogen storage device 25, and can also play a role in preventing wrong placement, and can also ensure that the hydrogen storage device 25 is not shaken after being placed in the gas cylinder bin 20. Because if the hydrogen storage device 25 is placed upside down, the bottle bottom 253 will interfere with the top plate 14 of the cabinet door 13, so that the cabinet door 13 cannot be closed, and the user can only place the hydrogen storage device 25 into the gas cylinder bin 20 in the correct way with the bottle bottom 253 facing inwards.

[0063] According to one embodiment of the utility model, cabinet body 11 is equipped with main control module 31, the side of each cabinet board 12 away from cabinet door 13 is equipped with signal plate 15 respectively, signal plate 15 is equipped with sub control mainboard, and each hydrogen storage device 25 is connected with corresponding sub control mainboard signal respectively.

[0064] That is, as shown in the figure, cabinet body 11 is provided with main control module 31, and the side of each cabinet board 12 away from cabinet door 13 is provided with signal plate 15, which can be an epoxy plate. Figure 7 Each signal plate 15 is respectively provided with a sub control mainboard, and each sub control mainboard can be in communication connection with two cylinder warehouses 20 on the cabinet board 12.

[0065] According to one embodiment of the utility model, the number of cabinet boards 12 and cabinet doors 13 is at least one, each cabinet board 12 is used for placing cylinder warehouse 20, and each cylinder warehouse 20 corresponds to at least one cabinet door 13.

[0066] In other words, as shown in the figure, the number of cabinet boards 12 and cabinet doors 13 is at least one, for example, the number of cabinet boards 12 and cabinet doors 13 is multiple, and the specific number can be set according to the length of the cabinet board 12. Figure 9 Figure 9 Each cabinet board 12 can be used for placing cylinder warehouse 20, and each cylinder warehouse 20 corresponds to at least one cabinet door 13.

[0067] The inside of cabinet door 13 is provided with lock catch 34 and top plate 14.

[0068] That is, as shown in the figure, the side of cabinet body 11 away from cabinet door 13 is provided with maintenance back door 36, and maintenance back door 36 is provided with door lock 37. Figure 4 Maintenance back door 36 can be opened to facilitate later maintenance.

[0069] ​​In some specific embodiments of the utility model, the cabinet 11 is provided with a two-dimensional code 41, the top of the cabinet 11 is provided with an antenna 42 and a solar panel 43, and the main control module 31 is electrically connected with the antenna 42. The cabinet 11 is also provided with a heat dissipation window 44 and a power line hole 45, and the bottom of the cabinet 11 is provided with a pulley 46.

[0070] In other words, as shown in Figure 5 and Figures 4 to 7 , the cabinet 11 is provided with a two-dimensional code 41, the two-dimensional code 41 is pasted above the cabinet 11, and the user can realize the functions of taking, returning and paying the rental fee of the hydrogen storage device 25 by scanning the two-dimensional code 41 through the intelligent device. The top of the cabinet 11 is provided with an antenna 42 and a solar panel 43, the solar panel 43 is fixed on the top of the cabinet 11 through a solar mounting bracket, and the cabinet can be powered by solar energy. Of course, in addition to solar power supply, the power supply mode of the utility model can also directly adopt power supply or other power supply modes, which will not be described in detail in the utility model. The main control module 31 is electrically connected with the antenna 42. The antenna 42 on the top of the cabinet 11 can communicate with external devices such as cloud servers and background databases, and update related data such as the data of borrowing and returning the hydrogen storage device 25, the quality of the hydrogen storage device 25 and the payment data of the user in real time.

[0071] After the hydrogen storage device 25 is put into the gas cylinder warehouse 20, the hydrogen storage device 25 is in contact with the weighing contact plate 27, the weighing contact plate 27 is connected with the weighing module 28, the current quality data of the hydrogen storage device 25 is obtained by weighing, and is transmitted to the sub-control mainboard behind the epoxy plate (signal plate 15), the calculation module on the sub-control mainboard calculates the current hydrogen content and other data of the hydrogen storage device 25, and then sends the related data to the main control module 31. The main control module 31 sends data to the cloud through the antenna 42. In short, according to the pre-measured quality of the light bottle (containing hydrogen storage metal), the quality of the hydrogen storage device 25 filled with hydrogen, and the current quality data of the hydrogen storage device 25, the current hydrogen content of the hydrogen storage device 25 can be calculated.

[0072] As shown in ​ , the cabinet 11 is also provided with a heat dissipation window 44 and a power line hole 45, the heat dissipation window 44 is arranged on the side of the cabinet 11, so that the heat in the cabinet 11 can be discharged in time. The power supply inside the hydrogen exchange cabinet 100 can be connected to the inside of the cabinet 11 through the power line hole 45 of the cabinet 11. The bottom of the cabinet 11 is provided with a pulley 46, which is convenient for moving or carrying the hydrogen exchange cabinet 100.

[0073] In the specific use process of the hydrogen exchange cabinet 100, the combination of the read-write card and the weighing module 28 can be used for accurately judging whether the user successfully borrows or returns the bottle. In the case that the user returns the hydrogen storage device 25, after scanning the code, the cabinet door 13 is opened, and after the hydrogen storage device 25 is put in, the door is closed. If the card reader recognizes the electronic chip, the weighing module 28 measures the mass of the hydrogen storage device 25, and the cabinet door sensor 32 detects that the lock catch 34 is clamped into the closed cabinet door 13, the user successfully returns the bottle.
