Description
Technical Field
[0001] This invention relates to the field of community emergency rescue stations, specifically to an integrated community emergency rescue station with a magnetic quick-start structure. Background Technology
[0002] With the increasing demand for public emergency medical equipment, community emergency medical stations with rapid-opening functions are gradually being promoted and popularized in public places as important facilities for deploying emergency supplies such as AEDs and first aid kits. Currently, most emergency medical stations use traditional mechanical locks or ordinary electromagnetic locks for their cabinet door locking mechanisms.
[0003] Traditional mechanical locks require users to operate them with a key or knob, and additional action is needed to lock them after closing the door. This operation is cumbersome and easy to forget, and cannot meet the "quick start" requirements in emergency scenarios. Although ordinary electromagnetic locks can achieve electronic control for quick opening, they need to be continuously powered to maintain the lock in standby mode, resulting in high power consumption. In addition, the lock tongue is a rigid metal part, which requires precise alignment between the cabinet door and the cabinet body when closing. This requires high installation accuracy, and after long-term use, the lock tongue is prone to jamming, failure to lock, or difficulty in opening due to door deformation, directly affecting the reliability of the quick start function.
[0004] Therefore, it is necessary to invent an integrated community emergency rescue station with a magnetic quick-start structure to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide an integrated community emergency rescue station with a magnetic quick-start structure, which solves the problem of poor reliability of the quick-start function of ordinary electromagnetic locks in the prior art by cooperating with the cabinet and electromagnetic quick-start mechanism and other parts.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated community emergency rescue station with a magnetic quick-opening structure, comprising a cabinet, the interior of which is provided with several storage cavities, each storage cavity containing a door for storing emergency supplies. Each door is fixedly connected to an electromagnetic quick-opening mechanism, which includes a mounting plate fixedly connected to the interior of the emergency supplies storage door.

A quick-opening protruding pad is fixedly connected to the upper surface of the flip plate, and a shaped locking tongue is fixedly connected to the lower surface of the flip plate. A first electromagnet is installed inside the root of the shaped locking tongue, and a first liquid bladder is opened inside the end of the shaped locking tongue. A wide oral cavity is opened on one side of the emergency supplies storage door corresponding to the shaped locking tongue. The end of the wide oral cavity away from the shaped locking tongue is connected to a compression deformation cavity, which is opened inside the emergency supplies storage door. The flip plate drives the shaped locking tongue to rotate, so that the first liquid bladder extends into the wide oral cavity and the compression deformation cavity, providing a structural basis for subsequent locking.

[0010] As a preferred embodiment of the present invention, three sets of hardening recesses are provided on the front side of the second liquid bladder, and three sets of limiting protrusions are fixedly connected to the side of the flip plate near the hardening recesses. The positions of the limiting protrusions and the hardening recesses correspond to each other, and the hardening recesses correspond to the limiting protrusions on the flip plate. When the door is closed, the limiting protrusions are pressed into the hardening recesses, and after the second liquid bladder hardens, it locks the limiting protrusions to form a surface lock.
[0011] In a preferred embodiment of the present invention, the second liquid bladder has a liquid cavity inside, and both the liquid cavity and the first liquid bladder are filled with magnetorheological fluid.

A sealing cylinder is fixedly connected to the bottom of the second liquid bladder, and a firing rod is slidably connected to the sealing cylinder, with the bottom end of the firing rod extending below the mounting frame. The firing rod and the sealing cylinder are connected by a compression spring. A trigger block is provided above the firing rod, and a resonance rod is fixedly connected to one side of the trigger block and to the inner wall of the second liquid bladder. Several sets of turbulence fins are fixedly connected to the side of the resonance rod away from the trigger block. When the electromagnet is energized, the fins harden to lock, and when the power is off, they liquefy to release the lock. Simultaneously, through the cooperation of the lifting groove and the wedge block, the mounting frame is lifted when the door is opened, causing the protective pad to reset. Furthermore, through the cooperation of the firing rod, trigger block, and other components, the magnetic particles settled inside the second liquid bladder are activated.
[0012] In a preferred embodiment of the present invention, a prompting block is fixedly connected to the front side of the emergency supplies storage door, corresponding to the position of the wide cavity; a display screen is fixedly connected to the top front side of the cabinet; a controller is fixedly connected to the front side of the cabinet; an arc-shaped guide lip is fixedly connected to the top wall of the wide cavity; a limiting buffer block is fixedly connected to the bottom wall of the wide cavity; a miniature dust scraper ring is fixedly connected to the front end of the limiting buffer block and the arc-shaped guide lip; a pressure relief groove is formed on the surface of the limiting buffer block; flexible dustproof wings are fixedly connected to both sides of the limiting buffer block; the display screen is used to display the equipment status; and the controller is used to receive signals and control the electromagnet to work.

An airflow channel is formed through the internal ventilation channel, the cooling fan and the air outlet slots to dissipate heat from the inside of the cabinet and the electromagnet.
[0014] In a preferred embodiment of the present invention, a rotating shaft is fixedly connected inside the emergency supplies storage door. The rotating shaft is rotatably connected to the surface of the storage cavity. A magnetic bracket is fixedly connected to the top of the storage cavity. A damping copper disc is disposed inside the magnetic bracket. The damping copper disc is fixedly connected to the top of the rotating shaft and rotatably connected to the top wall of the storage cavity.

[0015] In a preferred embodiment of the present invention, a plurality of sets of obstructing inclined plates are fixedly connected to the back side of the cabinet, the obstructing inclined plates obstructing the front of the air outlet slot, a heat-sensing plate is fixedly connected to the inner side of the inner cavity and is embedded in the interior of the mounting plate, a plurality of sets of heat dissipation fins are fixedly connected to the front end of the heat-sensing plate, an air intake filter is installed on the side of the mounting plate opposite to the heat dissipation fins and the air intake filter is connected to the inner air passage, and an insect-proof net is installed between two adjacent sets of obstructing inclined plates. The obstructing inclined plates prevent rainwater from entering the air outlet slot, and the insect-proof net prevents insects from entering the interior of the cabinet.
[0016] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. Through the cooperation of the flip plate and the spring pin, when the door is closed, the quick-opening protrusion contacts the cabinet door and pushes the flip plate from the tilted state to the vertical state. This rotation process simultaneously completes three actions: the irregular lock tongue extends into the wide mouth, the limiting protrusion is pressed into the hardened recess, and the spring pin is compressed and stored. At the same time, through the cooperation of the first electromagnet and the first liquid bladder, and the cooperation of the second electromagnet and the second liquid bladder, when the door is closed, the magnetorheological fluid is hardened simultaneously, realizing that point locking and surface locking are effective at the same time. This allows the user to complete the entire locking process with just one action of pushing the door, without any additional operation. 2. Through the cooperation of the irregularly shaped locking tongue and the first liquid bladder, the first liquid bladder is in a soft state when the door is closed, which can flow naturally and completely conform to the inner wall shape of the wide mouth and the extrusion deformation cavity. It can automatically adapt even if there is an installation deviation in the cabinet door. Through the cooperation of the first electromagnet and the first liquid bladder, the hardened shape of the first liquid bladder completely replicates the inner wall contour of the extrusion deformation cavity. At the same time, the mushroom head shape formed by the wide mouth and the extrusion deformation cavity and the mushroom head shape formed by the first electromagnet and the first liquid bladder form an inverted structure, realizing the mechanism of soft state adaptive insertion and hard state perfect locking. This completely solves the problem of dependence on precise alignment of traditional rigid locking tongues, greatly reduces the manufacturing and installation accuracy requirements, and improves product yield and on-site deployment convenience. 3. Utilizing the energized hardening characteristics of the first and second electromagnets, when the door is fully closed, the electromagnets are energized to generate a magnetic field, hardening the magnetorheological fluid within the first and second liquid bladders. This creates a dual locking system of point and surface locking, firmly locking the cabinet door. Utilizing the de-energized liquefaction characteristics of the first and second electromagnets, when the door is opened, the electromagnets are de-energized, the magnetic field disappears, the magnetorheological fluid returns to a liquid state, and the lock is instantly released. Through the cooperation of the spring pin and the protective pad, as the lock is released, the compressed spring pin releases its elastic potential energy, pushing the flip plate to rotate in the opposite direction, simultaneously pushing the protective pad to automatically open the cabinet door. Through the cooperation of the damping copper disc and the magnet bracket, a braking torque proportional to the rotational speed is generated during the door's opening process, achieving smooth opening and soft stopping.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] This invention provides, for example Figure 1-10The integrated community emergency rescue station with a magnetic quick-opening structure shown includes a cabinet 1. The cabinet 1 has several storage cavities 3 inside. Each storage cavity 3 has a first-aid supplies storage door 301. Each first-aid supplies storage door 301 is fixedly connected to an electromagnetic quick-opening mechanism 2. The electromagnetic quick-opening mechanism 2 includes a mounting plate 201 fixedly connected to the inside of the first-aid supplies storage door 301. An inner cavity 202 is formed on the outer side of the mounting plate 201. A flip plate 203 is rotatably connected inside the inner cavity 202, and a spring pin 212 is fixedly connected to the top of the inner cavity 202 corresponding to the position of the flip plate 203. A quick-opening protruding pad 2 is fixedly connected to the upper surface of the flip plate 203. 04. A shaped locking tongue 205 is fixedly connected to the lower surface of the flip plate 203. A first electromagnet 206 is installed inside the root of the shaped locking tongue 205. A first liquid bladder 207 is opened inside the end of the shaped locking tongue 205. A wide mouth 208 is opened on one side of the emergency supplies storage door 301 corresponding to the shaped locking tongue 205. The end of the wide mouth 208 away from the shaped locking tongue 205 is connected to a compression deformation cavity 209, which is opened inside the emergency supplies storage door 301. Through the flared shape of the wide mouth 208, the shaped locking tongue 205 moves the first liquid bladder 207 at a certain angle, thereby forcing the first liquid bladder 207 to deform in advance.
[0022] The rotating plate 203 drives the irregular locking tongue 205 to rotate, causing the first liquid bladder 207 to extend into the wide oral cavity 208 and the compression deformation cavity 209, providing a structural basis for subsequent locking. The width of the wide oral cavity 208 is greater than the width of the first electromagnet 206, and the thickness of the compression deformation cavity 209 is less than the thickness of the first liquid bladder 207. The wide oral cavity 208 and the compression deformation cavity 209 form a mushroom head shape, as do the first electromagnet 206 and the first liquid bladder 207. This allows the first liquid bladder 207 to be flattened and deformed by the compression deformation cavity 209 after insertion, forming an inverted locking mechanism after hardening. The inner cavity 202 is then moved away from the wide oral cavity 208. A slide block 211 is fixedly connected to the inner wall of one side. A protective pad 214 is provided inside the inner cavity 202. The protective pad 214 is slidably connected to the outer wall of the slide block 211, so that the protective pad 214 can be pushed to slide when the door is closed and pushed back to its original position by the spring pin 212 when the door is opened. Mounting brackets 213 are fixedly connected to both sides of the protective pad 214. A second liquid bladder 219 is fixedly connected to the front side of the protective pad 214 and is fixedly connected between the two sets of mounting brackets 213. A second electromagnet 215 is installed inside the protective pad 214 and is used for control. The second liquid bladder 219 is hardened and liquefied. Three sets of hardening recesses 218 are provided on the front side of the second liquid bladder 219. Three sets of limiting protrusions 216 are fixedly connected to the side of the flip plate 203 near the hardening recesses 218. The positions of the limiting protrusions 216 and the hardening recesses 218 correspond to each other. When the door is closed, the limiting protrusions 216 press into the hardening recesses 218. After the second liquid bladder 219 hardens, it locks the limiting protrusions 216, forming a surface lock. Through the cooperation of the flip plate 203 and the spring pin 212, the door closes quickly. When the protruding pad 204 contacts the cabinet door, it pushes the flip plate 203 to rotate from an inclined state to a vertical state. This rotation process simultaneously completes three actions: the irregular locking tongue 205 extending into the wide oral cavity 208, the limiting protrusion 216 pressing into the hardened recess 218, and the spring pin 212 compressing and storing energy. At the same time, through the cooperation of the first electromagnet 206 and the first liquid bladder 207, and the cooperation of the second electromagnet 215 and the second liquid bladder 219, when the door is closed, the magnetorheological fluid is hardened simultaneously, realizing that point locking and surface locking are effective at the same time. This allows the user to complete the entire locking process with just one action of pushing the door, without any additional operation.
[0023] like Figure 1-10As shown, the second liquid bladder 219 has a liquid cavity 217 inside, and both the liquid cavity 217 and the first liquid bladder 207 are filled with magnetorheological fluid. A lifting groove 210 is provided on the bottom of the mounting bracket 213 near the flip plate 203, and a wedge is fixedly connected to the flip plate 203 at the corresponding position of the lifting groove 210. A sealing cylinder 25 is fixedly connected to the bottom of the second liquid bladder 219, and a firing rod 26 is slidably connected to the sealing cylinder 25, with the bottom end of the firing rod 26 extending below the mounting bracket 213. The firing rod 26 and the sealing cylinder 25 are connected by a compression spring. A trigger block 27 is provided above the firing rod 26, and a resonance rod 28 is fixedly connected to one side of the trigger block 27. Attached to the inner wall of the second liquid bladder 219, the resonant rod 28, on the side away from the trigger block 27, is fixedly connected to several sets of turbulence fins 29. These fins harden and lock when the electromagnet is energized, and liquefy and release the lock when the power is off. Simultaneously, by lifting the inclined groove 210 in conjunction with the inclined block, the mounting bracket 213 is lifted when the door is opened, causing the protective pad 214 to reset. Simultaneously, through the cooperation of the firing rod 26, trigger block 27, and other components, the magnetic particles settled inside the second liquid bladder 217 are activated. Through the cooperation of the irregularly shaped locking tongue 205 with the first liquid bladder 207, the first liquid bladder 207 is in a soft state when the door is closed, allowing it to flow naturally and completely conform to the inner wall shape of the wide mouth 208 and the extrusion deformation cavity 209, even if there are installation deviations in the cabinet door. It can automatically adapt. Through the cooperation of the first electromagnet 206 and the first liquid bladder 207, the hardened shape of the first liquid bladder 207 completely replicates the inner wall contour of the extrusion deformation cavity 209. At the same time, the mushroom head shape formed by the wide mouth 208 and the extrusion deformation cavity 209 and the mushroom head shape formed by the first electromagnet 206 and the first liquid bladder 207 form an inverted interlocking structure, realizing a mechanism of soft-state adaptive insertion and hard-state perfect locking. This completely solves the problem of dependence on precise alignment in traditional rigid lock tongues, greatly reduces the manufacturing and installation accuracy requirements, and improves product yield and on-site deployment convenience. Through the energized hardening characteristics of the first electromagnet 206 and the second electromagnet 215, the electromagnets are energized to generate a magnetic field when the door is closed. The magnetorheological fluid in the first liquid bladder 207 and the second liquid bladder 219 hardens, forming a dual locking system of point locking and surface locking, firmly locking the cabinet door. Due to the de-energization liquefaction characteristics of the first electromagnet 206 and the second electromagnet 215, when the door is opened, the electromagnets are de-energized, the magnetic field disappears, the magnetorheological fluid returns to a liquid state, and the locking is released instantly. Through the cooperation of the spring pin 212 and the protective pad 214, at the same time as the locking is released, the compressed spring pin 212 releases elastic potential energy, pushing the flip plate 203 to rotate in the opposite direction, and at the same time pushing the protective pad 214 to automatically pop open the cabinet door. Through the cooperation of the damping copper plate 4 and the magnet bracket 5, a braking torque proportional to the rotation speed is generated during the opening of the cabinet door, realizing smooth opening and soft stopping.
[0024] like Figure 1-10As shown, a prompting block 15 is fixedly connected to the front side of the emergency supplies storage door 301, corresponding to the position of the wide oral cavity 208. A display screen 7 is fixedly connected to the top front side of the cabinet 1, and a controller 8 is fixedly connected to the front side of the cabinet 1. An arc-shaped guide lip 20 is fixedly connected to the top wall of the wide oral cavity 208, and a limit buffer block 22 is fixedly connected to the bottom wall of the wide oral cavity 208. A miniature dust scraper ring 21 is fixedly connected to the front end of the limit buffer block 22 and the arc-shaped guide lip 20. A pressure relief groove 23 is formed on the surface of the limit buffer block 22, and two sides of the limit buffer block 22 are fixedly connected to... The cabinet 1 includes a flexible dustproof wing 24, a display screen 7 for showing device status, a controller 8 for receiving signals and controlling the electromagnet, a sunshade 6 fixedly connected to the top of the cabinet 1, an internal ventilation duct 11 connected to each mounting plate 201, an internal heat dissipation cavity 12 on the back of the cabinet 1 containing a cooling fan 13, and several air outlet slots 14 on the back side of the cabinet 1 connected to the internal heat dissipation cavity 12. An airflow channel is formed through the internal ventilation duct 11, the cooling fan 13, and the air outlet slots 14. The cabinet 1's interior and electromagnet are cooled. A rotating shaft 16 is fixedly connected inside the emergency supplies storage door 301. The rotating shaft 16 is rotatably connected to the surface of the storage cavity 3. A magnetic support 5 is fixedly connected to the top of the storage cavity 3. A damping copper plate 4 is installed inside the magnetic support 5. The damping copper plate 4 is fixedly connected to the top of the rotating shaft 16 and rotatably connected to the top wall of the storage cavity 3. When the damping copper plate 4 rotates with the rotating shaft 16, it cuts the magnetic field of the magnetic support 5, generating damping and controlling the opening speed of the emergency supplies storage door, achieving soft opening and soft stopping. Several... A dry-group obstructing slope 9 is installed, which obstructs the front of the air outlet 14. A heat-sensing plate 19 is fixedly connected to the inner side of the inner cavity 202 and is embedded in the interior of the mounting plate 201. Several sets of heat dissipation fins 17 are fixedly connected to the front end of the heat-sensing plate 19. An air suction filter cover 18 is installed on the side of the mounting plate 201 opposite to the heat dissipation fins 17 and is connected to the inner air passage 11. An insect-proof net 10 is installed between two adjacent sets of obstructing slopes 9. The obstructing slopes 9 prevent rainwater from entering the air outlet 14, and the insect-proof net 10 prevents insects from entering the interior of the cabinet 1.
[0025] Working principle like Figure 1-10 As shown, when the user closes the emergency supplies storage door 301, the door rotates around the pivot 16 toward the cabinet body 1. When the door is close to the closed position, the quick-opening protrusion 204 fixed to the upper end of the flip plate 203 first contacts the corresponding surface of the cabinet body 1. The reaction force of the cabinet body 1 pushes the quick-opening protrusion 204, causing the flip plate 203 to start rotating around its rotation point, gradually changing from the initial tilted state to the vertical state.
[0026] As the flip plate 203 rotates, the irregularly shaped locking tongue 205 fixed to its lower surface moves forward. The first liquid bladder 207 at the end of the irregularly shaped locking tongue 205 is in a soft state and naturally extends into the wide oral cavity 208 under the thrust. Since the width of the wide oral cavity 208 is greater than the width of the first electromagnet 206, the root of the irregularly shaped locking tongue 205 can smoothly enter. The first liquid bladder 207 continues forward and enters the compression deformation cavity 209, which communicates with the wide oral cavity 208. Because the thickness of the compression deformation cavity 209 is less than the original thickness of the first liquid bladder 207, the first liquid bladder 207 is flattened by the upper and lower walls of the compression deformation cavity 209, and the soft first liquid bladder 207 automatically adheres to the inner wall of the compression deformation cavity 209. The shape of the locking tongue 205, and the fact that the root of the irregular locking tongue 205 is a hard body, ensures that the pressure and force on the deformation cavity 209 are large enough to push the first liquid bladder 207 into the interior of the deformation cavity 209. At the same time, since the shape of the wide oral cavity 208 is designed as a flared mouth, the irregular locking tongue 205 moves the first liquid bladder 207 at a certain angle. This angle forces the first liquid bladder 207 to deform in advance to adapt to the shape of the wide oral cavity 208 and the compression deformation cavity 209, thereby ensuring a smooth locking process and avoiding problems such as untimely deformation caused by direct impact.
[0027] At the same time, the three sets of limiting protrusions 216 fixed to the side of the flip plate 203 near the hardened recess 218 also move forward with the flip plate 203. At this time, the protective pad 214 is slidably connected to the inner cavity 202 through the slide block 211. The second liquid bladder 219 is fixed to the front side of the protective pad 214 through the mounting bracket 213. When the limiting protrusions 216 move forward, they are aligned with and pressed into the three sets of hardened recesses 218 on the front side of the second liquid bladder 219. The part of the second liquid bladder 219 pressed into by the limiting protrusions 216 undergoes local deformation. The soft second liquid bladder 219 automatically conforms to the outer surface shape of the limiting protrusions 216. At the same time, at the moment when the mounting bracket 213 descends to near the locking end point, the bottom end of the firing lever 26 and the inner cavity 202 are engaged. The bottom wall of cavity 202 contacts the trigger rod 26, and the reaction force of the bottom wall pushes the trigger rod 26 to slide upward along the sealed cylinder 25 for a limited stroke, overcoming the elastic force of the contraction spring. This causes the top of the trigger rod 26 to impact the trigger block 27, which transfers the impact kinetic energy to the resonance rod 28. The resonance rod 28 generates high-frequency micro-amplitude vibration inside the liquid cavity 217, which drives several sets of turbulence fins 29 fixed thereon to vibrate synchronously. The turbulence fins 29 then oscillate rapidly in the magnetorheological fluid, breaking up the existing particle sedimentation and stratification, allowing the soft magnetic particles to be uniformly suspended in the base fluid again. Therefore, each time the door is closed and locked, it automatically completes a stirring and homogenization just before the magnetorheological fluid hardens, ensuring that the particle distribution in the liquid bladder is uniform and the hardening strength is consistent when locked. This design eliminates the need for additional electrical control devices or manual maintenance, ensuring reliability from the source.
[0028] When the flip plate 203 rotates to the fully vertical position, the back of the flip plate 203 contacts and compresses the spring pin 212 at the top of the inner cavity 202. At this time, the irregular locking tongue 205 has fully extended into the bottom of the wide mouth 208, the limiting protrusion 216 has been fully pressed into the hardened recess 218, the spring pin 212 is compressed, and after the controller 8 detects the door closing signal, it immediately powers on the first electromagnet 206 and the second electromagnet 215.
[0029] When the first electromagnet 206 is energized, it generates a magnetic field. The magnetorheological fluid in the first liquid bladder 207 hardens instantly under the action of the magnetic field. The shape of the hardened first liquid bladder 207 completely replicates the inner wall contour of the extrusion deformation cavity 209. Because the wide cavity 208 and the extrusion deformation cavity 209 form a mushroom head shape, and the first electromagnet 206 and the first liquid bladder 207 also form a mushroom head shape, the hardened first liquid bladder 207 is firmly stuck in the extrusion deformation cavity 209. Any force pulling the cabinet door outward will cause the mushroom head part of the first liquid bladder 207 and the mushroom head part of the extrusion deformation cavity 209 to wed each other tightly, becoming increasingly tight and unable to come out, forming a point lock. At the same time, the second electromagnet 215 is energized to generate a magnetic field, and the magnetorheological fluid in the second liquid bladder 219 hardens synchronously. The hardened second liquid bladder 219 completely wraps around and locks the limiting protrusion 216. The cooperation of the three sets of limiting protrusions 216 and the three sets of hardened recesses 218 forms a multi-point lock, and any vibration or impact force in any direction will be dispersed and absorbed, forming a surface lock. The point lock and surface lock are effective at the same time, and the cabinet door is doubly locked. During the closing process, the flip plate 203 drives the irregular locking tongue 205 to move into the wide mouth 208. At this time, the arc-shaped guide lip 20 fixed to the top wall of the wide mouth 208 uses its arc surface structure to guide the first liquid bladder 207 to enter smoothly, preventing the hard edges from scratching the outer wall of the liquid bladder. At the same time, the limiting buffer block 22 located on the bottom wall of the wide mouth 208 absorbs the impact kinetic energy when closing the door to achieve silent closing. While the liquid bladder extends in, the micro dust scraper ring 21 connected to the front end of the arc-shaped guide lip 20 and the limiting buffer block 22 wipes and cleans the surface of the first liquid bladder 207. The flow-guiding pressure relief groove 23 ensures that the liquid bladder will not form a vacuum adsorption with the wall after hardening and expansion, ensuring instantaneous rebound when unlocking. When the cabinet door is completely closed, the flexible dustproof wings 24 set on both sides of the limiting buffer block 22 are deformed by pressure and fill the gaps in the door, thus forming an external dustproof and moisture-proof sealing barrier.
[0030] When the user issues an open-door command via controller 8, the first electromagnet 206 and the second electromagnet 215 are simultaneously de-energized, the magnetic field disappears, and the magnetorheological fluids in the first liquid bladder 207 and the second liquid bladder 219 instantly return to a liquid state after losing the magnetic field, thus simultaneously releasing the point lock and the surface lock. At the same time as the locks are released, the compressed spring pin 212 releases its elastic potential energy, pushing the flip plate 203 to rotate in the opposite direction. As the flip plate 203 rotates in the opposite direction, it causes the irregularly shaped locking tongue 205 to exit from the wide oral cavity 208, the first liquid bladder 207 retracts to its original position, and simultaneously causes the limiting protrusion 216 to exit from the hardened recess 218, pushing the protective pad 214 to slide outward along the slide block 211. As the protective pad 214 slides outward, it pushes the cabinet door to rotate outward around the pivot 16, causing the cabinet door to automatically open.
[0031] When the cabinet door is opened and continues to rotate, the rotating shaft 16 drives the damping copper disk 4 to rotate. The damping copper disk 4 cuts the magnetic field generated by the magnet bracket 5, generating eddy currents inside the copper disk. The interaction between the eddy currents and the magnetic field forms a braking torque that is proportional to the rotation speed. The faster the door opens, the greater the braking torque, thus achieving a smooth opening effect of rapid opening in the initial stage, uniform deceleration in the middle stage, and soft stopping in the final stage.
[0032] After the cabinet door is fully opened, the inclined block at the bottom of the flip panel 203 is separated from the lifting groove 210 at the bottom of the mounting bracket 213. When the user takes an item and pushes the door to close, the inclined block at the bottom of the flip panel 203 slides into the lifting groove 210, lifting the mounting bracket 213 and the protective pad 214 upwards, so that the protective pad 214 returns to the standby position, ready for the next closing of the door.
[0033] During the entire system operation, the sunshade 6 on the top of the cabinet 1 blocks direct sunlight, reducing the internal temperature of the cabinet 1 and the electromagnetic quick-start mechanism 2. The heat generated by the first electromagnet 206 and the second electromagnet 215 during the power-on locking or standby process is first transferred to the heat-sensing plate 19 and the heat dissipation fins 17 through the heat conduction path. At the same time, the negative pressure suction effect at the inlet of the air suction filter hood 18 forces the relatively low-temperature air from the outside to enter the inner cavity 202 area from the gaps around the emergency supplies storage door 301 or the pre-set air supply port of the cabinet 1. When cold air flows through the narrow channel between the heat dissipation fins 17, it undergoes forced convection heat exchange with the high-temperature fin surface, carrying away the heat from the fins. It is then drawn into the air intake filter 18, enters the inner ventilation duct 11, and flows along the duct to the inner heat dissipation cavity 12 at the back of the cabinet 1. The cooling fan 13 continuously operates to exhaust the hot air from the air outlet 14 into the cabinet 1. The obstruction plate 9 blocks the air outlet 14 in front of it to prevent rainwater from flowing back in. The insect net 10 prevents insects from entering the cabinet 1. The indicator block 15 is located on the front side of each emergency supplies storage door 301, corresponding to the wide mouth 208, allowing users to intuitively judge whether the locking tongue is in place. The display screen 7 displays the locking status and equipment information of each emergency supplies storage door 301 in real time, facilitating daily inspection and maintenance management. The interior of each emergency supplies storage door 301 stores AEDs, first aid kits, folding wheelchairs, stretchers, and other emergency supplies for immediate use.
[0034] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
