Description

Technical Field

[0001] This invention application relates to the field of hydrogen fuel cells, specifically to a hydrogen fuel cell mounting housing with a quick-release function. Background Technology

[0002] With the continuous development of clean energy technologies, hydrogen fuel cells are gradually becoming an important choice for power systems of high-performance equipment due to their advantages such as high energy density, environmental friendliness, and long driving range. However, in practical applications, the existing hydrogen fuel cell housings are mostly installed manually, resulting in low efficiency in daily maintenance and repair. Furthermore, in emergency situations, the housings lack intelligent sensing and automatic rapid disassembly functions, making it difficult to meet the needs of efficient emergency response and affecting the overall reliability and intelligence level of operation.

[0003] A currently published Chinese patent, CN222300690U, discloses a protective shell for a hydrogen fuel cell-based drone. The shell includes a cover, with a protective shell fitted to one end. A ceramic shell is embedded inside the protective shell. One end of the cover has a slot, and springs are equidistantly fixed to the surface of the slot. A pad, made of sponge, is fixed to the other end of each spring. A support frame is welded to the cross-section of the protective shell. Airbags are embedded in the opposing surfaces of two sets of support frames. A surrounding block is glued to one end of the cover outside the slot. An output end is fixedly installed on one long side surface of the cover near both sides. Hooks are fixedly installed on the two long side surfaces of the cover at the center. Heat sinks are embedded in the two short side surfaces of the protective shell at the center. The protective shell has docking grooves at both ends, and the surrounding block is embedded into these grooves. Buckles are symmetrically fixed to the two long side surfaces of the protective shell near both ends.

[0004] According to the aforementioned patent, the connection between the hook and the socket allows for easy assembly and disassembly of the battery. However, while this connection method enables rapid assembly and disassembly of the hydrogen fuel cell and improves operational convenience, it primarily relies on mechanical clips for fixing and locking. Frequent insertion and removal can lead to wear or deformation, resulting in decreased connection reliability. Furthermore, the lack of an automatic unlocking and rapid removal function for the battery module in emergency situations limits its applicability and safety under complex operating conditions.

[0005] Therefore, there is a need for a hydrogen fuel cell mounting housing with multi-mode quick-release function, which not only supports simple and quick manual unlocking to meet the needs of daily maintenance and battery replacement, but also can quickly and safely remove the battery module when an emergency is detected during equipment operation, thus comprehensively improving operational efficiency and safety. Summary of the Invention

[0006] To address the problems existing in the prior art, a hydrogen fuel cell mounting shell with quick-release function is provided. The two symmetrical side shells are controlled to move synchronously in opposite directions by a bidirectional actuator, which drives the bottom support plate to switch the support state of the flip plate. This enables the enclosure structure to automatically switch between the translation channel, the vertical channel and the sealed protective space. Combined with the multi-switch sensing mechanism of the stroke controller, the endpoint of each stroke is accurately identified to ensure stable switching between different quick-release modes.

[0007] To address the problems of existing technologies, this invention provides a hydrogen fuel cell mounting housing with a quick-release function, comprising a housing with an enclosure structure for accommodating a battery. The enclosure structure includes a base and an outer frame. When the base and outer frame are closed, they form a protective space for housing the battery. The protective space includes a buffer layer for providing enveloping protection for the battery. The base consists of two symmetrically arranged flaps, with the ends of the flaps rotatably connected to the housing. When the flaps are open, a vertical channel is formed, allowing the battery to fall vertically from the bottom of the housing. The outer frame consists of two symmetrically arranged side shells, each movable along the axis of the flaps on the housing. When the side shells are open, a translational channel is formed, allowing the battery to be horizontally pulled out from both ends of the housing. When the translational channel is opened for routine maintenance, the enclosure structure is in a lateral quick-release state. When the vertical channel is opened due to an emergency, the enclosure structure is in a bottom quick-release state. The housing is provided with a quick-release drive assembly for cooperating with the enclosure structure to open the translational or vertical channel.

[0008] Preferably, the two side shells can move synchronously in opposite directions. Each side shell has a support plate at its bottom that can horizontally support the two flaps. When the two side shells are fully opened and the support plate still supports the flaps, the translation channel is formed. When the two side shells continue to move outward until the support plate disengages from the flaps, the vertical channel is formed.

[0009] Preferably, the housing is provided with a slide rail, and each side shell is provided with a slider that is slidably disposed on the slide rail. The quick-release drive assembly includes a bidirectional driver that can drive the two sliders to move synchronously in opposite directions. The bidirectional driver has a first stroke end point that forms a translation channel, a second stroke end point that forms a vertical channel, and a third stroke end point that forms a protective space.

[0010] Preferably, the quick-release drive assembly further includes a travel controller electrically connected to the bidirectional driver. The travel controller is provided on the housing at a position corresponding to each tray for controlling the travel of the tray. Each tray is provided with a trigger element that cooperates with the corresponding travel controller to sense the end point of each travel.

[0011] Preferably, the stroke controller has a first switch, a second switch, and a third switch. When the trigger element triggers the first switch, the second switch, and the third switch respectively, the side shell is located at the first stroke end point, the second stroke end point, and the third stroke end point, respectively.

[0012] Preferably, the trigger has an inner pressure block disposed on the inner side of the tray and capable of pressing the first switch and the second switch in sequence as the side shell moves outward. The trigger also has an outer pressure block disposed on the outer side of the tray and capable of pressing the third switch as the side shell moves inward.

[0013] Preferably, a side block is provided on all four sides of the bottom of the housing to stably support the corresponding support plate.

[0014] Preferably, each flap has a rotating shaft rotatably connected to the housing on both sides, and a torsion spring is provided between each rotating shaft and the housing. When the battery falls and squeezes the flap due to gravity, the torsion spring is in a torsional state, and at this time, the vertical channel is formed between the two flaps.

[0015] Preferably, each flap has a block on both sides, and a blocking block is provided on the housing at the position corresponding to each block. When the block contacts the blocking block, the torsion spring is in normal state, and the two flaps are flush.

[0016] Preferably, each flip plate has two side strips symmetrically arranged on the surface supporting the battery along the axis of rotation, and a slot for inserting or removing the battery is formed between the two side strips.

[0017] The advantages of this application compared to the prior art are:

[0018] 1. This invention utilizes a bidirectional actuator to control two symmetrical side shells to move synchronously in opposite directions along the rotation axis of the flap, thereby switching the support state of the bottom support plate on the flap and achieving automatic conversion of the enclosure structure between a translational channel and a vertical channel. Specifically, through the reciprocating motion and stroke control of the push-pull rod, the side shells can form a translational channel for horizontal battery extraction, a vertical channel for vertical battery detachment, and a closed state of sealed protective space at different stroke endpoints, meeting different needs for daily maintenance and emergency disassembly.

[0019] Because both the outer frame and base are made of rubber and have a cushioning layer, the stability and sealing of the battery during flight are ensured. This allows for quick assembly and disassembly of the hydrogen fuel cell and reliable protection, improving operational efficiency and flight safety.

[0020] 2. This invention application achieves precise positioning and automated control of the quick-release process of the hydrogen fuel cell mounting shell by cooperating with the stroke controller and the trigger element, that is, by combining the first switch, the second switch and the third switch to correspond to the stroke endpoints of the translation channel, the vertical channel and the protective space respectively.

[0021] As the side shell moves along the slide rail driven by the bidirectional actuator, the triggers on the tray move synchronously and press the corresponding limit switches in sequence, feeding back the current status signal to the control system, thereby accurately identifying the mode of the enclosure structure. Specifically, by pressing different switches with the inner and outer pressure blocks, the side shell is identified and locked at different travel endpoints, ensuring stable switching between lateral quick-release, bottom quick-release, and sealed closed states. This improves the reliability of quick-release operation and ensures rapid disassembly and stable installation of the battery under various operating conditions.

[0022] 3. This invention application utilizes side blocks to support the tray, ensuring the stability of battery installation and improving the load-bearing capacity of the base. During the period when the tray supports the flip-up plate, the contact between the blocked block and the retaining block ensures that the two flip-up plates are flush, guaranteeing stable support for the battery.

[0023] Furthermore, the slots on the flip plate provide guides and limits for battery installation and removal, preventing displacement and improving operational smoothness. This enhances the overall stability and quick-release response capability of the hydrogen fuel cell mounting housing. Attached Figure Description

[0038] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0039] See Figures 1-11As shown, a hydrogen fuel cell mounting housing with quick-release function includes a housing 1. The housing 1 is provided with a surrounding structure 3 for accommodating a battery 2. The surrounding structure 3 includes a base 31 and an outer frame 32. When the base 31 and the outer frame 32 are in a closed state, they form a protective space for housing the battery 2. The protective space is provided with a buffer layer 21 for providing wrap-around protection for the battery 2. The base 31 is composed of two symmetrically arranged flaps 311. The ends of the two flaps 311 that are away from each other are rotatably connected to the housing 1. When the two flaps 311 are in an open state, a space is formed that allows the battery 2 to be installed from the housing 1. The housing 1 has a vertical channel at the bottom. The outer frame 32 is composed of two symmetrically arranged side shells 321. The two side shells 321 can move along the axis of the flap 311 on the housing 1. When the two side shells 321 are open, a translation channel is formed that allows the battery 2 to be pulled out horizontally from both ends of the housing 1. When the battery 2 opens the translation channel for routine maintenance, the enclosure structure 3 is in a lateral quick-release state. When the battery 2 opens the vertical channel in an emergency, the enclosure structure 3 is in a bottom quick-release state. The housing 1 is provided with a quick-release drive assembly 4 to cooperate with the enclosure structure 3 to open the translation channel or the vertical channel.

[0040] The base 31 and outer frame 32 of the enclosure structure 3 are both made of rubber. When the base 31 and outer frame 32 are completely closed, they fit tightly together to form a well-sealed protective space.

[0041] The outer frame 32 has an opening for wiring the battery 2, and the housing 1 has a disconnection structure that automatically cuts off the connection points to ensure that the battery 2 can be automatically and quickly removed from the enclosure structure 3 through a vertical channel in an emergency. The disconnection structures are not shown in the figure.

[0042] When the hydrogen fuel cell 2 needs to be installed or removed from the equipment, the operator first activates the quick-release drive assembly 4 on the housing 1. If it is a routine maintenance scenario involving the replacement of the battery 2, the quick-release drive assembly 4 controls the two symmetrical side shells 321 of the outer frame 32 to move along the rotation axis 3111 of the flap 311, causing them to separate to both sides, thus forming a horizontal translation channel. At this time, the enclosure structure 3 enters the lateral quick-release state, and the operator can smoothly pull out the hydrogen fuel cell 2 from both ends of the housing 1 along the translation channel for inspection, replacement, or maintenance.

[0043] As the outer frame 32 opens, the wiring opening on the outer frame 32 works in conjunction with the disconnection structure. The disconnection structure can automatically identify whether it is in a disassembly state and quickly cut off the connection between the battery 2 and the device, ensuring safe separation under any circumstances, especially in emergency situations, to prevent potential hazards.

[0044] In another scenario, such as an emergency during flight, like the hydrogen fuel cell 2 overheating, catching fire, or emitting smoke, the quick-release drive assembly 4 immediately activates the two flaps 311, opening the previously closed base 31 and creating a vertical channel extending downwards from the bottom of the casing 1. At this point, the enclosure structure 3 enters a quick-release bottom state, allowing the hydrogen fuel cell 2 to quickly detach vertically from the protective space under gravity, thus achieving rapid disassembly.

[0045] In its normally closed state, the base 31 and the outer frame 32 fit tightly together, and the buffer layer 21 effectively cushions vibrations and impacts during flight. When the base 31 and the outer frame 32 are completely closed, the resulting protective space has excellent sealing performance, which can isolate the influence of external environmental factors such as rain and dust, providing a stable working environment for the hydrogen fuel cell 2.

[0046] See Figures 3-11 As shown, the two side shells 321 can move synchronously in opposite directions. Each side shell 321 has a support plate 322 at its bottom that can horizontally support the two flaps 311. When the two side shells 321 are fully opened and the support plate 322 still supports the flaps 311, the translation channel is formed. When the two side shells 321 continue to move outward until the support plate 322 disengages from the flaps 311, the vertical channel is formed.

[0047] When the two side shells 321 begin to move under the action of the quick-release drive assembly 4, the two side shells 321 move synchronously in opposite directions, that is, they slide towards or away from each other to the left and right sides respectively. As the side shells 321 continue to move, when the two side shells 321 are fully opened but still in contact with the flap 311 and supported by the support plate 322, the flap 311 remains in the closed position. At this time, the surrounding structure 3 forms a translation channel for the horizontal extraction of the battery 2, and enters the lateral quick-release state.

[0048] When the operator issues a further disassembly command, causing the two side shells 321 to continue moving outward synchronously to a certain distance, the support plate 322 at the bottom of the side shell 321 gradually detaches from the support of the flip plate 311. The flip plate 311 is no longer constrained by the outer frame 32 and flips outward around the rotational connection point between it and the shell 1 under the gravity of the battery 2, thereby forming a vertical channel that runs downward through the bottom of the shell 1. At this time, the surrounding structure 3 switches to the bottom quick-release state, realizing the conversion from a translational channel to a vertical channel, ensuring that the hydrogen fuel cell 2 can quickly and safely complete the disassembly process in different scenarios.

[0049] See Figures 1-11 and Figure 13As shown, the housing 1 is provided with a slide rail 11, and each side housing 321 is provided with a slider 12 that is slidably disposed on the slide rail 11. The quick-release drive assembly 4 includes a bidirectional driver that can drive the two sliders 12 to move synchronously in opposite directions. The bidirectional driver has a first stroke end point that forms a translation channel, a second stroke end point that forms a vertical channel, and a third stroke end point that forms a protective space.

[0050] The bidirectional actuator has a push-pull rod 41 arranged along the length direction perpendicular to the slide rail 11 and a connecting rod 411 respectively hinged between the two sliders 12 and the push-pull rod 41. The push-pull rod 41 is movable along the length direction perpendicular to the slide rail 11. The driving source for driving the push-pull rod 41 is not shown in the figure.

[0051] When the bidirectional driver is started, the push-pull rod 41 reciprocates along the length direction perpendicular to the slide rail 11, and transmits the motion to the sliders 12 through the connecting rod 411, which is hinged at both ends between the two sliders 12 and the push-pull rod 41, so that the two sliders 12 slide synchronously in opposite directions on the slide rail 11 of the housing 1.

[0052] As the push-pull rod 41 gradually moves to the end of the first stroke, the two side shells 321 are driven to unfold outward to a specific position. At this time, the support plate 322 at the bottom of the side shell 321 still supports the flap 311 in the base support 31, and the surrounding structure 3 forms a translation channel for the horizontal extraction of the battery 2.

[0053] If the push-pull rod 41 continues to move to the end of the second stroke, the two side shells 321 will further expand outward until their bottom support plate 322 disengages from the support of the flap 311, thereby forming a vertical channel for the battery 2 to fall vertically under the action of gravity.

[0054] When the push-pull rod 41 retracts to the end of the third stroke, the two sliders 12 drive the side shell 321 to close inward, the outer frame 32 and the base 31 fit tightly together, and the flap 311 is supported by the support plate 322 again, together forming a well-sealed protective space, providing a stable and sealed installation environment for the hydrogen fuel cell 2.

[0055] See Figure 1 , Figure 2 and Figure 6 As shown, the quick-release drive assembly 4 also includes a stroke controller 42 electrically connected to the bidirectional driver. The housing 1 is provided with the stroke controller 42 at a position corresponding to each tray 322 for controlling the stroke of the tray 322. Each tray 322 is provided with a trigger 43 that cooperates with the corresponding stroke controller 42 to sense the end point of each stroke.

[0056] When the bidirectional drive moves the two side shells 321 along the slide rail 11, the stroke controller 42 in the quick-release drive assembly 4 monitors and controls the entire movement process in real time. When the side shell 321 moves the tray 322 to a specific stroke position, the movement of the trigger 43 will be sensed by the corresponding stroke controller 42, which will send a signal to the control system to confirm whether the first stroke end point, the second stroke end point, or the third stroke end point has been reached.

[0057] Through the sensing cooperation between the trigger 43 and the stroke controller 42, the stroke controller 42 can accurately identify each state transition node, ensuring that the bidirectional drive stops or switches actions at the correct position, realizing automated and precise control of the opening and closing state of the enclosure structure 3, thereby ensuring the safe and stable disassembly and sealing protection of the hydrogen fuel cell 2 under different operating modes.

[0058] See Figure 5-Figure 11 As shown, the stroke controller 42 has a first switch 421, a second switch 422 and a third switch 423. When the trigger 43 triggers the first switch 421, the second switch 422 and the third switch 423 respectively, the side shell 321 is located at the first stroke end point, the second stroke end point and the third stroke end point respectively.

[0059] When the side shell 321 moves along the slide rail 11 under the drive of the bidirectional driver, the stroke controller 42 set on the shell 1 accurately positions the side shell 321 through the first switch 421, the second switch 422 and the third switch 423 inside it, where each switch corresponds to a specific stroke state.

[0060] As the tray 322 at the bottom of the side shell 321 moves synchronously, the trigger 43 mounted on the tray 322 will contact the corresponding switch in sequence.

[0061] When the trigger 43 triggers the first switch 421, it indicates that the side shell 321 has moved to the designated position to form the translation channel, and at this time the enclosure structure 3 is in the lateral quick-release state.

[0062] If the side shell 321 continues to move until the trigger 43 triggers the second switch 422, it indicates that the tray 322 has disengaged from the support of the flip plate 311, the side shell 321 has reached the designated position to form the vertical channel, and the surrounding structure 3 switches to the bottom quick-release state.

[0063] When the trigger 43 triggers the third switch 423 during the inward closing process of the side shell 321, it indicates that the outer frame 32 and the bottom support 31 have been closed, the protective space is sealed in place, and the system has entered normal working condition.

[0064] Through the precise sensing and signal feedback of the first switch 421, the second switch 422 and the third switch 423, the control system can accurately identify the end point of each stroke, realize precise control of the entire quick-release process, and ensure that quick release or installation is completed under different circumstances.

[0065] See Figure 5-Figure 11 As shown, the trigger 43 has an inner pressure block 431 disposed inside the tray 322 and capable of moving outward with the side shell 321 to press the first switch 421 and the second switch 422 in sequence. The trigger 43 also has an outer pressure block 432 disposed outside the tray 322 and capable of moving inward with the side shell 321 to press the third switch 423.

[0066] When the side shell 321 moves outward under the drive of the bidirectional driver, the inner pressure block 431 on the trigger 43 moves synchronously with the side shell 321 and first contacts the first switch 421 on the stroke controller 42, applying pressure to press it down, indicating that the side shell 321 has reached the first stroke end point of forming the translation channel.

[0067] As the side shell 321 continues to move outward, the inner pressure block 431 advances further until it presses against the second switch 422, confirming that the side shell 321 has reached the second end point of the stroke that forms the vertical channel.

[0068] As the side shell 321 moves inward, the outer pressure block 432 on the trigger 43 moves accordingly until it presses the third switch 423, thus confirming that the outer frame 32 and the bottom support 31 are completely closed, the protective space is sealed, and the third stroke ends.

[0069] By pressing different switches with the inner pressure block 431 and the outer pressure block 432 respectively, precise control of the quick-release state is achieved, ensuring that the quick-release mode switches accurately between various states.

[0070] See Figures 6-12 As shown, a side block 323 is provided around the bottom of the housing 1 to stably support the corresponding support plate 322.

[0071] When the side shell 321 moves along the slide rail 11 under the drive of the bidirectional driver, the bottom support plate 322 will move synchronously with the movement of the side shell 321. To ensure that the support plate 322 remains stable during the movement, each side block 323 cooperates with the bottom of the support plate 322 to provide support for the support plate 322, preventing the support plate 322 from being insufficient due to excessive pressure from the battery 2, thereby ensuring that the support plate 322 remains horizontal throughout the entire stroke and can accurately cooperate or disengage with the flip plate 311.

[0072] The stable support provided by the edge block 323 further enhances the smoothness and reliability of the outer frame 32 during quick disassembly, ensuring that the enclosure structure 3 can achieve precise switching and firm support in different states.

[0073] See Figures 6-12 As shown, each flap 311 has a rotating shaft 3111 on both sides that is rotatably connected to the housing 1. Each rotating shaft 3111 and the housing 1 are provided with a torsion spring 3112. When the battery 2 falls and squeezes the flap 311 due to gravity, the torsion spring 3112 is in a torsional state. At this time, the vertical channel is formed between the two flaps 311.

[0074] When battery 2 needs to be quickly removed due to an emergency, quick-release drive assembly 4 is activated and controls side shell 321 to continue moving outward, causing tray 322 to disengage from the support of flip plate 311. At this time, under the pressure of the falling battery 2, the two flip plates 311 flip downward around the rotating shaft 3111 on both sides that is rotatably connected to the shell 1.

[0075] Meanwhile, the torsion springs 3112 set between each rotating shaft 3111 and the housing 1 enter a torsional state under the influence of the rotation of the rotating shaft 3111, storing a certain amount of elastic potential energy. As the flap 311 gradually opens, a vertical channel is formed between the two, running through the bottom of the housing 1. Under the action of gravity, the hydrogen fuel cell 2 quickly detaches vertically from the surrounding structure 3, completing the emergency quick disassembly operation.

[0076] During this process, the torsion spring 3112 not only provides the rebound force required for the flap 311 to reset, but also enhances the stability of the flap 311 during the opening process, ensuring the smooth formation of the vertical channel, and assists the flap 311 to return to the initial closed state during the subsequent closing process.

[0077] To ensure that the spring force of the torsion spring 3112 is sufficient to reliably return the flap 311 to a horizontal position without hindering the opening of the flap 311 due to the gravity of the battery 2, the spring force of the torsion spring 3112 is set slightly higher than the torque generated by the weight of the flap 311 itself. This ensures that it can overcome factors such as friction and stably return to a horizontal position. However, it is also lower than the effective component of the rotational torque generated when the weight of the battery 2 acts on the flap 311, thereby avoiding hindering the flap 311 from opening naturally due to the gravity of the battery 2.

[0078] See Figures 6-12 As shown, each flap 311 has a block 312 on both sides, and a blocking block 313 is provided on the housing 1 at the position corresponding to each block 312. When the block 312 contacts the blocking block 313, the torsion spring 3112 is in normal state, and the two flaps 311 are in a flush state.

[0079] When the flap 311 is in the closed state, the blocking blocks 312 on both sides of each flap 311 are in close contact with the blocking blocks 313 at the corresponding positions on the housing 1. At this time, the flap 311 remains horizontal and is flush with the flap 311 on the other side of the base 31. The torsion spring 3112 is in a normal state of natural unforced state and does not apply additional torsional torque to the rotating shaft 3111.

[0080] As the quick-release process begins, the side shell 321 causes the support plate 322 to disengage from the flip plate 311. Under the gravity of the battery 2, the flip plate 311 begins to rotate downward around the pivot 3111. The stop block 312 then disengages from the contact with the blocking block 313. At the same time, the torsion spring 3112 enters a torsion state, storing the elastic potential energy required for reset.

[0081] During the closing process, as the flap 311 gradually returns to its original position and re-fits with the blocking block 313, the blocking block 312 abuts against the blocking block 313 again, restricting the flap 311 from continuing to rotate, so that the two flaps 311 return to a flat state. At this time, the torsion spring 3112 also returns to its normal state, ensuring that the flap 311 maintains a stable and flat closed structure in the non-disassembly state, and together with the support plate 322, provides a stable bottom support for the hydrogen fuel cell 2.

[0082] See Figure 4 and Figure 12 As shown, each flap 311 has two side strips 314 symmetrically arranged on the surface supporting the battery 2 along the axis of the rotating shaft 3111, and a slot for inserting or removing the battery 2 is formed between the two side strips 314.

[0083] When the hydrogen fuel cell 2 needs to be installed into the enclosure structure 3, the operator smoothly inserts the battery 2 along the slot direction to ensure that the battery 2 is in a stable and centered position in the base 31.

[0084] During disassembly, whether the battery is pulled out horizontally through the translation channel or dropped through the vertical channel, the slot can effectively guide the movement of the battery 2, avoiding displacement and thus improving the smoothness of the entire quick disassembly process.

[0085] This invention uses a bidirectional driver to control two symmetrical side shells 321 to move synchronously in opposite directions along the rotation axis 3111 of the flap 311, causing the bottom support plate 322 to switch its support state on the flap 311, thus realizing the automatic conversion of the enclosure structure 3 between the translational channel, the vertical channel, and the sealed protective space. Combined with the multi-switch sensing mechanism of the stroke controller 42, it accurately identifies the end point of each stroke, ensuring stable switching between different quick-release modes.

[0086] Simultaneously, the support of the support plate 322 by the side block 323, the limiting cooperation between the blocked block 312 and the blocking block 313, and the guiding function of the slot further enhance the stability of battery 2 installation and the smoothness of the disassembly process. This enables rapid and safe installation and disassembly of the hydrogen fuel cell 2, improving operational efficiency and emergency response capabilities during flight missions.

[0087] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
