Description

Technical Field

[0001] This utility model relates to the field of power output mechanism technology, specifically a power output mechanism for a hydrogen fuel cell system power generation device. Background Technology

[0002] Hydrogen fuel cells directly convert chemical energy into electrical energy. Hydrogen gas is delivered to the anode plate of the fuel cell. Through the action of a catalyst, an electron is separated from the hydrogen atom. The hydrogen ion, having lost its electron, passes through the proton exchange membrane and reaches the cathode plate. The separated electron travels through an external circuit to the cathode plate, generating current in the external circuit. To output power from the hydrogen fuel cell, a wiring harness needs to be plugged into the fuel cell's power output interface.

[0003] For example, in CN115692784A, a hydrogen energy storage fuel cell power generation device is disclosed. This solution can control the hydrogen production rate in each placement chamber to maintain a consistent hydrogen production rate. At the same time, the rotating rod drives the hydrogen production pipe to rotate and cooperate with the outer sleeve. The staggered sealing between the outer sleeve and the through hole of each placement chamber is achieved, thereby realizing the regulation and control of the hydrogen production rate of the hydrogen production system.

[0004] The above solution outputs power through a power data interface, but the output interface is not protected. The output interface is susceptible to interference and damage from the external environment when the wire harness is not inserted. Furthermore, there is no limit to the wire harness after it is inserted, and the wire harness is easily pulled away from the interface by external force. Utility Model Content

[0005] The purpose of this utility model is to provide a power output mechanism for a hydrogen fuel cell system power generation device, so as to solve the problem mentioned in the background art that the existing power output mechanisms for hydrogen fuel cell system power generation devices are not convenient for protecting the output interface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power output mechanism for a hydrogen fuel cell system power generation device, comprising: a battery box and an adjustment mechanism, wherein an output interface is installed on one side of the battery box.

[0007] A slide bar is fixed on the side of the battery box near the output interface. A connecting block a is slidably connected to the outside of the slide bar. A protective box is movably connected to the bottom of the connecting block a via a rotating shaft. An adjustment mechanism for adjusting the state of the protective box is provided at the bottom of the protective box. The adjustment mechanism includes a connecting block b that is movably connected to the bottom of the protective box via a rotating shaft.

[0008] Preferably, a spring is fixedly connected inside the connecting block b, and a locking block is fixedly connected to the top of the spring.

[0009] Preferably, the card block has a through groove inside, and the through groove is slidably connected to the lever.

[0010] Preferably, the outer side of the card block is slidably connected to the connecting block b, and the top and bottom pivots of the connecting block b are on the same axis.

[0011] Preferably, the bottom of the protective box is provided with slots a and b that match the card block, and the internal thread of the connecting block b is connected with a bidirectional threaded rod.

[0012] Preferably, the two ends of the bidirectional threaded rod are movably connected to the battery box via bearings, and the middle part of the lever is movably connected to the connecting block b via a rotating shaft.

[0013] Compared with existing technologies, the beneficial effects of the power output mechanism of this hydrogen fuel cell system power generation device are as follows: The power output mechanism of this hydrogen fuel cell system power generation device, by moving a lever to move a locking block, disengages the locking block from the slot b. Then, the two sets of protective boxes are rotated and merged. The two sets of protective boxes can shield the output interface on one side of the battery box, thus protecting the power output mechanism of the power generation device. When it is necessary to insert the wiring harness into the output interface, the lever can be moved to disengage the locking block from the slot a, and the protective box can be rotated 90° to engage the slot b with the locking block. At this time, the two sets of protective boxes will unfold, allowing the wiring harness to be inserted into the output interface. After insertion, the bidirectional threaded rod can be rotated to move the two sets of protective boxes in opposite directions, limiting the insertion of the wiring harness plug. Thus, the above operations facilitate the protection of the power output mechanism of the hydrogen fuel cell system power generation device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a power output mechanism for a hydrogen fuel cell system power generation device, comprising: a battery box 1 and an adjustment mechanism 6, wherein an output interface 2 is installed on one side of the battery box 1.

[0023] A slide bar 3 is fixed on the side of the battery box 1 near the output interface 2. A connecting block a4 is slidably connected to the outside of the slide bar 3. A protective box 5 is movably connected to the bottom of the connecting block a4 via a rotating shaft. An adjustment mechanism 6 for adjusting the state of the protective box 5 is provided at the bottom of the protective box 5. The adjustment mechanism 6 includes a connecting block b61 that is movably connected to the bottom of the protective box 5 via a rotating shaft. A through hole matching the slide bar 3 is opened inside the connecting block a4. The slide bar 3 and the connecting block a4 form a sliding structure.

[0024] A spring 62 is fixedly connected inside the connecting block b61, and a locking block 63 is fixedly connected to the top of the spring 62. A through groove 65 is opened inside the locking block 63, and the through groove 65 is slidably connected to the lever 64. The outer side of the locking block 63 is slidably connected to the connecting block b61. The rotating shaft at the top and bottom of the connecting block b61 are on the same axis. The bottom of the protective box 5 has a locking groove a7 and a locking groove b8 that match the locking block 63. A bidirectional threaded rod 9 is threaded inside the connecting block b61. The two ends of the bidirectional threaded rod 9 are movably connected to the battery box 1 through bearings. The middle part of the lever 64 is movably connected to the connecting block b61 through a rotating shaft. A sliding groove that matches the locking block 63 is opened inside the connecting block b61. A rotating groove is opened inside the connecting block b61, and the rotating groove is slidably connected to the lever 64. The connecting block b61 and the locking block 63 form a sliding structure, and the lever 64 forms a rotating structure with the connecting block b61 through the rotating shaft.

[0025] In specific implementation, when protecting the output interface 2, the power output mechanism of the hydrogen fuel cell system power generation device rotates by turning the lever 64 in the adjusting mechanism 6. The rotating lever 64 moves in the through groove 65 inside the locking block 63, thereby moving the locking block 63 and pressing the spring 62 at one end. When the locking block 63 moves out of the locking groove b8, the same operation can be performed on the other set of protective boxes 5. Then, the two sets of protective boxes 5 are rotated and merged. After merging, the locking groove a7 at the bottom of the protective box 5 will engage with the locking block 63, completing the limiting of the protective box 5. The two sets of protective boxes 5 can block the output interface 2 on one side of the battery box 1, thus completing the protection of the power output mechanism of the power generation device.

[0026] When the wiring harness needs to be inserted into the output interface 2, the lever 64 can be moved to disengage the locking block 63 from the locking slot a7, and the protective box 5 can be rotated 90° to engage the locking slot b8 with the locking block 63. At this time, the two sets of protective boxes 5 will unfold, and the wiring harness can be inserted into the output interface 2. After insertion, the bidirectional threaded rod 9 can be rotated to drive the two sets of connecting blocks b61 in a threaded manner, causing the two sets of connecting blocks b61 and the protective box 5 to move in opposite directions. The protective box 5 can limit the plug of the wiring harness through the raised vertical plate on the inner side to prevent the wiring harness from detaching from the connection with the output interface 2 when it is accidentally pulled. In this way, the above operation can facilitate the protection of the power output mechanism of the hydrogen fuel cell system power generation device.

[0027] In summary: When using the power output mechanism of the hydrogen fuel cell system power generation device, the components in battery box 1 will continue to generate electricity. When power is needed, the wiring harness can be inserted into the output interface 2 on one side of battery box 1 to output power. This is the characteristic of the power output mechanism of the hydrogen fuel cell system power generation device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
