Description

TECHNICAL FIELD

[0001] The present application relates to the field of hydrogen fuel cells, in particular to a hydrogen fuel cell installation shell with quick disassembly function. BACKGROUND

[0002] With the continuous development of clean energy technology, hydrogen fuel cells gradually become an important choice for high-performance equipment power systems due to their high energy density, environmental friendliness, and strong endurance. However, in practical applications, the existing hydrogen fuel cell installation shell is mostly manually disassembled, which is low in efficiency for daily maintenance and repair. At the same time, in emergency situations, the shell lacks intelligent sensing and automatic quick disassembly function, which is difficult to meet the needs of efficient emergency handling, affecting the reliability and intelligent level of the overall operation.

[0003] The currently disclosed Chinese patent with the authorization publication number CN222300690U is a protective shell based on unmanned aerial vehicle hydrogen fuel cell, which includes a cover, one end of the cover is connected with a protective shell, the inner side of the protective shell is embedded with a ceramic shell, one end of the cover is provided with a hollow groove, the surface of the hollow groove is fixedly connected with springs at equal intervals, the other end of the spring is fixedly connected with a pad plate, the material of the pad plate is sponge, the truncated surface of the protective shell is welded and fixed with a pad frame, the opposite surfaces of the two groups of pad frames are embedded and installed with airbags, one end of the cover is glued and fixed with a surrounding block outside the hollow groove, the surface of one long side of the cover is fixedly installed with an output end near the two sides, the surface of the two long sides of the cover is fixedly installed with a hanging buckle at the middle part, the surface of the two short sides of the protective shell is embedded and installed with a radiator at the middle part, the two ends of the protective shell are provided with a butt joint groove, the surrounding block is embeddedly connected with the butt joint groove, the surface of the two long sides of the protective shell is symmetrically fixedly installed with a buckle seat near the two ends.

[0004] According to the above-mentioned patent, the disassembly and assembly of the battery can be easily completed through the connection of the hanging buckle and the buckle seat. However, although the quick disassembly and assembly of the hydrogen fuel cell is realized through the connection of the hanging buckle and the buckle seat, the operation convenience is improved, but it mainly relies on the mechanical buckle to realize the fixation and locking, which is easy to wear or deform in the process of frequent plugging and unplugging, resulting in the decrease of connection reliability. At the same time, it lacks the function of automatically unlocking and quickly removing the battery module in emergency situations, which limits its applicability and safety in complex working conditions.

[0005] Therefore, there is a need for a hydrogen fuel cell installation shell with multi-mode quick disassembly function, which not only supports simple and convenient 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 the operation of the equipment, thereby improving the operation efficiency and safety.

DETAILED DESCRIPTION

[0038] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in combination with the drawings and specific embodiments.

[0039] Reference is made to Figures 1-11As shown, a hydrogen fuel cell mounting shell with quick release function comprises a shell 1, which is provided with a surrounding structure 3 for accommodating a battery 2, the surrounding structure 3 comprises a bottom support 31 and an outer frame 32, when the bottom support 31 and the outer frame 32 are in a closed state, they form a protective space for accommodating the battery 2, and a buffer layer 21 is arranged in the protective space to provide wraparound protection for the battery 2, the bottom support 31 is composed of two symmetrical flaps 311, one end of each of the two flaps 311 is rotatably connected to the shell 1, and when the two flaps 311 are opened, a vertical channel is formed for the battery 2 to vertically fall from the bottom of the shell 1, the outer frame 32 is composed of two symmetrical side shells 321, each of the two side shells 321 can move along the axis of the flap 311 on the shell 1, and when the two side shells 321 are opened, a translation channel is formed for the battery 2 to be horizontally extracted from both ends of the shell 1, when the battery 2 is opened for daily maintenance, the surrounding structure 3 is in a lateral quick release state, and when the battery 2 is opened for emergency, the surrounding structure 3 is in a bottom quick release state, and the shell 1 is provided with a quick release driving assembly 4 for opening the translation channel or the vertical channel of the surrounding structure 3.

[0040] The bottom support 31 and the outer frame 32 of the surrounding structure 3 are both made of rubber material, and when the bottom support 31 and the outer frame 32 are completely closed, they are tightly attached to form a well-sealed protective space.

[0041] An opening is formed on the outer frame 32 for wiring of the battery 2, and a disconnecting structure is arranged on the shell 1 to automatically cut off the connection point to ensure that the battery 2 can be automatically released from the surrounding structure 3 through the vertical channel in an emergency. The disconnecting structure is not shown in the figure.

[0042] When the hydrogen fuel cell 2 needs to be installed or removed on the equipment, the operator first starts the quick release driving assembly 4 on the shell 1, if it is a battery 2 replacement in a daily maintenance scenario, the quick release driving 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, so that they are separated to the two sides, thereby forming a horizontal translation channel. At this time, the surrounding structure 3 enters a lateral quick release state, and the operator can smoothly extract the hydrogen fuel cell 2 along the translation channel from both ends of the shell 1 for inspection, replacement or maintenance operation.

[0043] At the same time that the outer frame 32 is opened, the wiring opening formed on the outer frame 32 works with the disconnecting structure, the disconnecting structure can automatically identify whether it is in a disassembly state at present, and quickly cut off the connection point between the battery 2 and the equipment, to ensure safe separation in any case, especially in an emergency, to prevent hidden dangers.

[0044] In another case, for example, in the event of an emergency during flight, such as overheating, fire, smoke, etc. of the hydrogen fuel cell 2, the quick-release drive assembly 4 immediately drives the two flaps 311 to unfold, so that the originally closed bottom support 31 is opened, forming a vertical channel extending downward from the bottom of the shell 1. At this time, the surrounding structure 3 enters the bottom quick-release state, and the hydrogen fuel cell 2 can quickly fall vertically from the protection space under the action of gravity, and is separated from the device, realizing quick release.

[0045] In the normal closed state, the bottom support 31 is tightly fitted between the outer frame 32, and the vibration and impact during flight can be effectively buffered through the buffer layer 21. When the bottom support 31 and the outer frame 32 are completely closed, the protection space formed has good sealing performance, which can isolate the influence of external environmental factors such as rain and dust, and provide a stable working environment for the hydrogen fuel cell 2.

[0046] Referring to Figures 3-11 As shown, the two side shells 321 can move synchronously and reversely, and each side shell 321 is provided with a support plate 322 capable of horizontally supporting the two flaps 311. When the two side shells 321 are completely opened and the support plates 322 still support the flaps 311, the translational channel is formed, and when the two side shells 321 continue to move outward until the support plates 322 are separated from the flaps 311, the vertical channel is formed.

[0047] When the two side shells 321 start to move under the action of the quick-release drive assembly 4, the two side shells 321 move synchronously and reversely, i.e. slide towards or away from each other. With the continuous movement of the side shell 321, when the two side shells 321 are completely opened but still in contact with the flaps 311 and supported by the support plates 322, the flaps 311 remain in the closed position, and at this time the surrounding structure 3 forms a translational channel for the battery 2 to be pulled out horizontally, and enters the lateral quick-release state.

[0048] When the operator issues further disassembly instructions, the support plates 322 at the bottom of the side shells 321 gradually separate from the support of the flaps 311, the flaps 311 are no longer constrained by the outer frame 32, and are opened by turning outward around the rotating connection point of the battery 2 and the shell 1 under the action of gravity, thereby forming a vertical channel 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 the translational channel to the vertical channel, and ensuring that the hydrogen fuel cell 2 can quickly and safely complete the disassembly process in different scenarios.

[0049] Referring to Figures 1-11 and Figure 13As shown, the shell 1 is provided with slide rails 11, each side shell 321 is provided with a sliding block 12 slidingly arranged on the slide rail 11, and the quick-release driving assembly 4 comprises a bidirectional driver capable of driving the two sliding blocks 12 to synchronously and reversely move.

[0050] The bidirectional driver has a push-pull rod 41 arranged along a direction perpendicular to the length direction of the slide rail 11, and connecting rods 411 respectively hinged between the two sliding blocks 12 and the push-pull rod 41, the push-pull rod 41 is capable of moving along a direction perpendicular to the length direction of the slide rail 11, and a 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 reciprocally moves along a direction perpendicular to the length direction of the slide rail 11, and the connecting rods 411 respectively hinged between the two sliding blocks 12 and the push-pull rod 41 transmit the movement to the sliding blocks 12, so that the two sliding blocks 12 synchronously and reversely slide on the slide rail 11 of the shell 1.

[0052] With the gradual movement of the push-pull rod 41 to the first stroke end point, the two side shells 321 are driven to outwardly expand to a specific position, at which time the supporting plate 322 at the bottom of the side shell 321 still supports the flap 311 in the bottom 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 second stroke end point, the two side shells 321 further outwardly expand until the supporting plate 322 at the bottom thereof is separated from the support of the flap 311, thereby forming a vertical channel for the vertical falling of the battery 2 under the action of gravity.

[0054] When the push-pull rod 41 retreats to the third stroke end point, the two sliding blocks 12 drive the side shells 321 to inwardly close, the outer frame 32 and the bottom support 31 are tightly fitted, the flap 311 is supported by the supporting plate 322 again, and a good sealing protection space is formed for the stable and airtight installation environment of the hydrogen fuel cell 2.

[0055] Referring to Figure 1 , Figure 2 and Figure 6 As shown, the quick-release driving assembly 4 further comprises a stroke controller 42 electrically connected with the bidirectional driver, the shell 1 is provided with the stroke controller 42 for controlling the stroke of each supporting plate 322 at a position corresponding to each supporting plate 322, and each supporting plate 322 is provided with a trigger 43 cooperating with the corresponding stroke controller 42 to sense each stroke end point.

[0056] When the two side shells 321 are moved along the slide rail 11 by the bidirectional driver, the travel controller 42 in the quick-release driving assembly 4 monitors and controls the entire movement process in real time. When the side shell 321 drives the supporting plate 322 to reach a specific travel position, the movement of the trigger 43 will be sensed by the corresponding travel controller 42, which feeds back a signal to the control system to confirm whether the first travel end, the second travel end or the third travel end is reached.

[0057] Through the sensing cooperation between the trigger 43 and the travel controller 42, the travel controller 42 can accurately identify each state transition node, ensuring that the bidirectional driver stops or switches actions at the correct position, realizing the automated and accurate control of the opening and closing state of the surrounding structure 3, and thus ensuring the safe, stable disassembly and sealing protection of the hydrogen fuel cell 2 in different operation modes.

[0058] Referring to Figures 5-11 As shown, the travel 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 positions of the side shell 321 are the first travel end, the second travel end and the third travel end respectively.

[0059] When the side shell 321 is moved along the slide rail 11 by the bidirectional driver, the travel controller 42 arranged 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, each of which corresponds to a specific travel state.

[0060] As the supporting plate 322 at the bottom of the side shell 321 moves synchronously, the trigger 43 installed on the supporting plate 322 will contact the corresponding switch in turn.

[0061] When the trigger 43 triggers the first switch 421, it indicates that the side shell 321 has moved to a designated position forming a translation channel, and at this time the surrounding structure 3 is in a side 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 supporting plate 322 has been separated from the support of the flap 311, and the side shell 321 reaches a designated position forming a vertical channel, and the surrounding structure 3 switches to a bottom quick-release state.

[0063] When the trigger 43 triggers the third switch 423 during the inward closing of the side shell 321, it indicates that the outer frame 32 and the bottom support 31 have completed the closing, and the protection space is sealed in place, entering the normal working state.

[0064] Through the precise induction 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 of each stroke, realize precise control of the entire quick release process, and ensure that the quick release or installation is completed under different conditions.

[0065] Referring to Figures 5-11 As shown, the trigger piece 43 has an inner pressing block 431 arranged inside the supporting plate 322 and capable of following the outward movement of the side shell 321 to press the first switch 421 and the second switch 422 in turn, and the trigger piece 43 also has an outer pressing block 432 arranged outside the supporting plate 322 and capable of following the inward movement of the side shell 321 to press the third switch 423.

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

[0067] With the continuous outward movement of the side shell 321, the inner pressing block 431 further advances until it presses the second switch 422, confirming that the side shell 321 has reached the second stroke end point forming the vertical channel.

[0068] During the inward movement of the side shell 321, the outer pressing block 432 on the trigger piece 43 moves until it presses the third switch 423, thereby confirming that the outer frame 32 and the bottom support 31 have been completely closed, the protective space is sealed, and the third stroke end point is reached.

[0069] Through the pressing of the inner pressing block 431 and the outer pressing block 432 on different switches, precise control of the quick release state is realized, ensuring accurate switching between each state of the quick release mode.

[0070] Referring to Figures 6-12 As shown, the shell 1 is provided with an edge block 323 around the bottom to stably support the corresponding supporting plate 322.

[0071] When the side shell 321 moves along the slide rail 11 under the driving of the bidirectional driver, the supporting plate 322 at the bottom of the side shell 321 will displace synchronously with the movement of the side shell 321. To ensure that the supporting plate 322 remains stable during movement, each edge block 323 cooperates with the bottom of the supporting plate 322 to form a supporting effect on the supporting plate 322, preventing the supporting plate 322 from being insufficiently supported due to excessive pressure from the battery 2, thereby ensuring that the supporting plate 322 is always in a horizontal state during the entire stroke and can accurately cooperate with or disengage from the flap 311.

[0072] The stable support of the side block 323 further improves the stability and reliability of the outer frame 32 during the quick disassembly process, ensuring that the surrounding structure 3 can achieve precise switching and firm support in different states.

[0073] Referring to Figures 6-12 As shown, each flap 311 is provided with a rotating shaft 3111 rotatably connected to the shell 1, and a torsional spring 3112 is arranged between each rotating shaft 3111 and the shell 1. When the battery 2 falls due to gravity and presses the flap 311, the torsional spring 3112 is in a twisted state, and at this time, the two flaps 311 form the vertical channel.

[0074] When the battery 2 needs to be quickly disassembled due to an emergency, the quick disassembly drive assembly 4 is started and controls the side shell 321 to continue moving outward, so that the supporting plate 322 is separated from the support of the flap 311, and at this time, the two flaps 311 are turned downward around the rotating shaft 3111 rotatably connected to the shell 1 on both sides of the battery 2 under the pressure of the falling battery 2.

[0075] At the same time, the torsional spring 3112 arranged between each rotating shaft 3111 and the shell 1 is affected by the rotation of the rotating shaft 3111 and enters a twisted state, storing a certain amount of elastic potential energy. As the flaps 311 gradually open, a vertical channel is formed through the bottom of the shell 1 between the two flaps 311, and the hydrogen fuel cell 2 quickly falls vertically from the surrounding structure 3 under the action of gravity, completing the emergency quick disassembly operation.

[0076] During this process, the torsional spring 3112 not only provides the rebound force required for the reset of the flap 311, but also enhances the stability of the flap 311 during the opening process, ensuring that the vertical channel is smoothly formed, and assisting the flap 311 to return to the initial closed state during the subsequent closing process.

[0077] In order to ensure that the torsional spring 3112 has a spring force that can reliably reset the flap 311 to a horizontal state and does not hinder the opening of the flap 311 due to the gravity of the battery 2, the spring force of the torsional spring 3112 is set to be slightly higher than the torque generated by the gravity of the flap 311 itself, so as to ensure that it can stably return to the horizontal position overcoming friction and other factors. However, it is also lower than the effective component of the rotational moment generated by the gravity of the battery 2 acting on the flap 311, so as to avoid hindering the natural opening of the flap 311 due to the gravity of the battery 2.

[0078] Referring to Figures 6-12 As shown, each flap 311 is provided with a stop block 312, and the shell 1 is provided with a blocking block 313 corresponding to each stop block 312. When the stop block 312 contacts the blocking block 313, the torsional spring 3112 is in a normal state, and at this time, the two flaps 311 are in a flush state.

[0079] When the flap 311 is in a closed state, the blocking block 312 provided on both sides of each flap 311 is in close contact with the blocking block 313 at the corresponding position on the shell 1, at this time, the flap 311 remains horizontal and forms a flush state with the other side of the flap 311 of the bottom support 31, and the torsional spring 3112 is in a natural and unforced normal state and does not exert an additional torsional moment on the rotating shaft 3111.

[0080] With the start of the quick disassembly process, the side shell 321 drives the support plate 322 to disengage from supporting the flap 311, and the flap 311 starts to rotate downward around the rotating shaft 3111 under the action of gravity of the battery 2, and the blocking block 312 is disengaged from the contact with the blocking block 313, and at the same time, the torsional spring 3112 enters a torsional state and stores elastic potential energy required for resetting.

[0081] In the closing process, when the flap 311 gradually resets and recombines with the blocking block 313, the blocking block 312 again abuts against the blocking block 313, limiting the flap 311 from continuing to rotate, so that the two flaps 311 restore to a flush state, at this time, the torsional spring 3112 also restores to a normal state, ensuring that the flap 311 remains stable and flat in a closed structure in a non-disassembly state, and the support plate 322 provides stable bottom support for the hydrogen fuel cell 2.

[0082] Referring to Figure 4 and Figure 12 As shown, the surface of each flap 311 for supporting the battery 2 is symmetrically provided with two edge strips 314 along the axis direction of the rotating shaft 3111, and a clamping groove for inserting or extracting the battery 2 is formed between the two edge strips 314.

[0083] When the hydrogen fuel cell 2 needs to be installed into the surrounding structure 3, the operator inserts the battery 2 along the direction of the clamping groove, ensuring that the battery 2 is in a stable and centered position in the bottom support 31.

[0084] In the disassembly process, whether it is extracted horizontally through the translation channel or falls through the vertical channel, the clamping groove can effectively guide the movement of the battery 2 and avoid the occurrence of deviation, thereby improving the smoothness of the entire quick disassembly process.

[0085] The present application controls the synchronous and reverse movement of the two symmetric side shells 321 along the rotating shaft 3111 of the flap 311 through the bidirectional driver, drives the bottom support plate 322 to switch the support state of the flap 311, and realizes the automatic conversion of the surrounding structure 3 between the translation channel, the vertical channel and the sealed protection space. Combined with the multi-switch sensing mechanism of the travel controller 42, the end points of each stroke are accurately identified, ensuring stable switching between different quick disassembly modes.

[0086] Meanwhile, the support of the side block 323 to the supporting plate 322, the limiting cooperation of the blocking block 312 and the blocking block 313, and the guiding effect of the clamping groove further improve the stability of the battery 2 installation and the smoothness of the disassembly process. The hydrogen fuel cell 2 is quickly and safely disassembled, and the operation efficiency and the emergency response capability in the flight task are improved.

[0087] The above embodiments only express one or several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
