Description

Technical Field

[0001] This invention relates to the field of modular charging technology, specifically to a modular charging mechanism for power supply units and its management method. Background Technology

[0002] In fields such as communication base stations, data centers, and industrial control, especially in the power transmission and distribution of ground AC charging piles, multiple backup power supplies (such as lithium battery packs and lead-acid batteries) are often required to work together to realize modular charging mechanisms in order to ensure uninterrupted power supply to the equipment.

[0003] Traditional charging equipment's over-temperature protection is mostly in the "temperature sensor + power off" mode, which can only cut off the charging circuit, but the faulty power supply is still in the charging cabinet and in close contact with other normal power supplies; the abnormally high temperature power supply will continue to dissipate heat (the heat dissipation temperature is greater than 80℃), causing the temperature of the surrounding power supplies to rise (the temperature rise is greater than 10℃), triggering a chain thermal runaway; if the power supply has a short circuit and catches fire, the fire can easily spread rapidly, causing a batch of power supplies to burn. Summary of the Invention

[0004] The present invention provides a modular charging mechanism for power supply units and a management method thereof to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular charging mechanism for power supply groups, including a power supply placement platform, wherein the power supply placement platform provides placement space for multiple power supply groups in an array layout; A modular mechanism is provided on the outside of the power supply platform and is arranged corresponding to the power supply platform. It is used to perform centralized modular charging of multiple power supplies to achieve synchronous or independent power supply. The temperature control mechanism is embedded inside the power supply platform and is adapted to each power supply. When an abnormally high temperature occurs during the charging process, the temperature control mechanism can automatically discharge the corresponding power supply and cut off the electrical connection between the power supply and the modular mechanism to avoid safety hazards. An external discharge mechanism is located outside the power supply platform and is connected to the temperature control mechanism. It is used to receive the abnormally high-temperature power discharged by the temperature control mechanism and to dissipate the heat. The modular mechanism includes an integrated charger, which is fixedly installed on the outside of the power supply platform. The integrated charger has symmetrically connected plugs on both sides. The plug end of the plug is connected to the power socket. A cable holder is sleeved on the outside of the plug. The cable holder is fixedly connected to the outside of the integrated charger. The cable holder is used to fix the wire part of the connector plug and prevent it from being pulled loose.

[0006] Preferably, the temperature control mechanism includes a first spring, the inside of the power supply platform is provided with a T-shaped groove, the first spring is fixedly connected to the bottom of the T-shaped groove, and the top of the first spring is fixedly connected to a curved panel, which is slidably adapted to the T-shaped groove. When the power supply is placed on the power supply placement platform, the power supply is pressed and matched with the curved side of the curved panel, driving the curved panel to compress the first spring and retract into the T-shaped groove; after the power supply is placed in place, the first spring returns to its original position, and the vertical side of the curved panel extends out of the T-shaped groove, limiting the horizontal movement of the placed power supply.

[0007] Preferably, the power supply platform has a sliding groove inside, and a sliding frame is slidably fitted inside the sliding groove. Both ends of the sliding frame are fixedly connected to telescopic sealing plates. The end of the telescopic sealing plate away from the sliding frame is fixedly connected to the inner wall of the sliding groove and expands and contracts synchronously with the movement of the sliding frame. Both sides of the telescopic sealing plate are fixedly connected with elastic sealing strips to fill the gap between the telescopic sealing plate and the inner wall of the groove.

[0008] Preferably, the inner sliding adapter of the sleeve frame is fitted with a limiting plate, and both ends of the limiting plate are fixedly connected to an outer strip, and the outer side of the outer strip is fixedly connected to a telescopic rod; When the power supply is placed inside the power supply platform, the front end of the power supply first presses against the curved panel to fit, and then continues to be pushed in and presses against the limiting plate, driving the limiting plate to move into the interior of the power supply platform. At the same time, it causes the telescopic sealing plates on both sides of the sliding frame to expand and contract. When the power supply is fully placed in place, the limiting plate and the curved panel together clamp and fix the power supply, achieving radial limiting.

[0009] Preferably, the limiting plate has a vertical groove inside, the inner wall of the vertical groove is slidably adapted to a slider, the outer side of the slider is fixedly connected to a deep groove ball bearing, the inner wall of the deep groove ball bearing is extruded and adapted to a first sleeve, the inner wall of the first sleeve is slidably adapted to a second sleeve, and the inner wall of the second sleeve is slidably adapted to a third sleeve, the three forming a telescopic sleeve structure. The top of the limiting plate has a through hole, and the No. 3 sleeve extends through the through hole to the top of the limiting plate. The melt is fixedly connected to the top of the No. 3 sleeve and to the top of the limiting plate. The melt is a low melting point material that can melt when exposed to high temperatures.

[0010] Preferably, a second spring is fixedly connected to the top of the inner cavity of the third sleeve, and the bottom end of the second spring is fixedly connected to the bottom of the inner cavity of the sleeve slide frame. In the initial state, the second spring is in a state of forced tension and torsion, and the limiting is achieved by fixing the melt. When the power supply experiences abnormally high temperatures, the high temperature is conducted to the molten metal and melts it. The limit of the second spring is released, and it is then compressed and reset while rotating. The third sleeve, which is fixedly connected to the top of the second spring, moves down and rotates, causing the second sleeve and the first sleeve to rotate synchronously and gradually contract.

[0011] Preferably, a gear is fixedly connected to the outer side of the first sleeve, and a gear ring is fixedly connected to the bottom of the first gear; The limiting plate has a compensation groove inside, and a threaded column is slidably fitted inside the compensation groove. A second gear is threadedly connected to the outside of the threaded column. The outside of the second gear is meshed with the first gear and the gear ring respectively. The thickness of the second gear is less than the thickness of the first gear. The bottom of the inner cavity of the sliding frame is provided with a first tooth groove and a second tooth groove. The first tooth groove is fitted with the second gear, and the second tooth groove is fitted with the gear ring.

[0012] Preferably, the external discharge mechanism includes a bottom connecting column, which is fixedly installed inside the power supply placement platform. A three-way plate is fixedly connected to the bottom of the bottom connecting column, and a built-in spring telescopic rod is fixedly connected to the end of the three-way plate away from the bottom connecting column. The outer side of the bottom connecting column is slidably fitted with a docking plate. Both ends of the docking plate are fixedly connected with double-pass support plates. The top of the double-pass support plates is used to abut and limit the output end of the built-in spring telescopic rod, restricting the extension and retraction of the built-in spring telescopic rod in the initial state.

[0013] Preferably, the outer side of the power supply placement platform is provided with a groove, and a sliding block is slidably adapted in the groove. A support plate is fixedly connected to the top of the sliding block. The support plate is used to support the power supply, and its surface is provided with a rough structure to increase the friction between it and the power supply. A connecting rope is fixedly connected to the outer side of the sliding block, and the end of the connecting rope away from the sliding block is fixedly connected to the output end of the built-in spring telescopic rod. A guide plate is fixedly installed on the outer end face of the power supply platform, which is inclined to guide the power supply to slide down. A support shaft is fixedly installed on the outer side of the guide plate. A heat sink is rotatably installed inside the support shaft through a shaft. A rocker is fixedly connected to the outer side of the heat sink. The top of the rocker is pressed and fitted against the bottom of the double-pass support plate.

[0014] A management method for modular charging of power supply units includes the following steps: Step 1: When the power supply to be charged is pushed into the power supply placement platform, the front end squeezes the curved panel to compress the No. 1 spring and retract it into the T-shaped groove; after the tail of the power supply is disengaged, the curved panel resets and abuts against the tail. At the same time, the front end of the power supply pushes the limiting plate to move and causes the telescopic sealing plate to deform. Finally, the limiting plate and the curved panel (cooperatively clamp and complete the radial fixation of the power supply). Step 2: After the power supply is fixed, connect the plug to the power socket. The integrated charger enables centralized modular charging of multiple power supplies, and each power supply can be powered independently. The cable holder fixes the connection between the plug and the charger to prevent the cable from breaking when disconnected. Step 3: When the power supply is abnormally high, the melt at the top of the limit plate melts, the second spring resets and contracts, causing the first sleeve, the second sleeve, and the third sleeve to rotate and contract synchronously; through the meshing transmission of the first gear, the gear shifter, and the second gear, the limit plate moves down along the vertical groove and retracts into the sleeve frame, and finally the gear ring is embedded in the second gear groove, and the second gear falls into the first gear groove. Step 4: The limiting plate moves down, causing the telescopic rod and the double-pass support plate to move down, releasing the constraint on the built-in spring telescopic rod. Its retraction pulls the power supply through the moving block and the support plate, causing the socket and plug to separate, and the power supply slides into the guide plate; at the same time, the double-pass support plate squeezes the rocker plate, driving the heat sink plate to rotate and rock up through the support seat, lifting and limiting the downward sliding power supply.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the power supply is pushed in, the curved panel and the limiting plate work together to clamp and fix it radially, preventing the power supply from shifting during charging and causing the plug to come off; the cable holder fixes the connection part to prevent the connection from breaking when plugging, unplugging or shifting, ensuring the stability of integrated centralized charging and adapting to the modular needs of charging multiple power supplies at the same time.

[0016] 2. When the power supply experiences abnormally high temperatures, the molten metal melts upon heating, triggering a linkage mechanism. Through spring reset and gear transmission, the limit plate automatically retracts, quickly releasing the clamp on the power supply. Simultaneously, the connection between the power supply and the connector is automatically disconnected, preventing safety hazards such as short circuits and fires caused by high temperatures, providing double safety protection for the charging process.

[0017] 3. In an emergency, the built-in spring telescopic rod retracts, causing the support plate to move and push the abnormal power source outward and away from the charging station. It then slides onto the heat dissipation plate via the guide plate. This not only prevents the abnormal power source from affecting the normal charging of other power sources, but also quickly isolates the faulty power source, facilitating timely repairs by staff and improving maintenance efficiency.

[0018] 4. The power supply does not require manual fixing when placed, and the mechanical structure automatically completes the positioning and clamping, making the insertion and removal process simple; the device can simultaneously meet the needs of centralized charging and independent power supply of multiple power supplies, and is suitable for use in different scenarios; the integrated design of emergency detachment and heat dissipation support can complete the abnormal handling without manual intervention, reducing the difficulty of operation and labor intensity.

Detailed Implementation

[0036] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 16 The present invention provides a technical solution: Example 1, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the power supply platform 1 of the modular charging mechanism has four power supply slots arranged in an array on its surface. The size of each slot is adapted to the lithium battery pack. The modular mechanism 2 is fixed to its outer side by bolts. The power supply platform 1 has T-shaped slots inside, with one slot in each slot. A No. 1 spring 31 is welded to the bottom of the T-shaped slot, and a curved panel 32 is welded to the top of the No. 1 spring 31. One side of the curved panel 32 is curved, and the other side is vertical. It slides within the T-shaped slot. The surface of the power supply platform 1 has a sliding groove. A sliding frame 33 slides within the groove. Telescopic sealing plates 34, made of telescopic flame-retardant rubber, are welded to both ends of the sliding frame 33. The end of the telescopic sealing plate 34 away from the sliding frame 33 is welded to the inner wall of the groove. Elastic sealing strips, made of silicone, are welded to both sides of the telescopic sealing plate 34 to fill the gaps. A limiting plate 35 slides within the sliding frame 33. External connecting strips 36 are welded to both ends of the limiting plate 35. The outer side of the connecting strip 36 is welded with a telescopic rod 37; the inner side of the limiting plate 35 has a vertical groove 38, the inner wall of the vertical groove 38 is adapted to a slider 39, the outer side of the slider 39 is nested with a deep groove ball bearing 30, the inner wall of the deep groove ball bearing 30 is interference-fitted with a first sleeve 301, the inner side of the first sleeve 301 is adapted to a second sleeve 302, the inner side of the second sleeve 302 is adapted to a third sleeve 303, the three of which constitute a telescopic sleeve structure; the top of the limiting plate 35 has a through hole, the third sleeve The tube 303 extends through the perforation to the top of the limiting plate 35, but does not exceed the top of the limiting plate 35. The top of the third sleeve 303 is welded with a melt 305, which is made of a low melting point alloy with a melting point of 60°C. The melt 305 is welded and fixed to the top of the limiting plate 35. The top of the inner cavity of the third sleeve 303 is welded with a second spring 304, which is made of stainless steel and is initially subjected to forced stretching and torsion. The bottom of the second spring 304 is welded to the bottom of the inner cavity of the sliding frame 33.

[0038] The first sleeve 301, the second sleeve 302, and the third sleeve 303 form a hollow telescopic rod. Both the first sleeve 301 and the second sleeve 302 have T-shaped grooves inside. The second sleeve 302 slides into the T-shaped groove inside the first sleeve 301, and the third sleeve 303 slides into the T-shaped groove inside the second sleeve 302. Therefore, when the top of the hollow telescopic rod is rotated, i.e., when the third sleeve 303 is rotated, the second spring 304 simultaneously undergoes torsional deformation and axial tensile deformation. These two deformations cause the second spring 304 to store elastic potential energy, namely torsional potential energy and tensile potential energy. The extension, contraction, and rotation of the hollow telescopic rod are rigidly linked to the deformation of the second spring 304. Its extension is a direct manifestation of the axial tension of the second spring 304, and its rotation is a direct manifestation of the torsion of the second spring 304.

[0039] When the top of the telescopic rod is released, that is, when the melt 305 at the top of the No. 3 sleeve 303 melts, the elastic potential energy of the No. 2 spring 304 will drive it to restore its original free length and helical posture: on the one hand, the recovery of the tensile deformation of the No. 2 spring 304 will generate an axial contraction force, pulling the telescopic rod to contract axially in sync; on the other hand, the recovery of the torsional deformation of the No. 2 spring 304 will generate a reverse torsional torque, causing the telescopic rod to rotate in the opposite direction in sync. Therefore, the two will achieve synchronous reset of contraction and rotation.

[0040] Four sets of lithium battery packs to be charged are pushed into the four placement slots of the power supply placement platform 1 respectively; the front end of the power supply is pressed and matched with the arc surface of the curved panel 32, forcing the curved panel 32 to compress the first spring 31 and retract into the T-shaped groove; the power supply is pushed in, and the front end of the power supply contacts and presses against the limiting plate 35, driving the limiting plate 35 to move into the power supply placement platform 1, and simultaneously driving the telescopic sealing plates 34 on both sides of the sliding frame 33 to telescopically deform, and the elastic sealing strip tightly fits the inner wall of the sliding groove to prevent dust from entering.

[0041] When the power supply is fully placed in position, the tail of the power supply disengages from the arc surface of the curved panel 32, and the first spring 31 elastically returns to its original position. The vertical side of the curved panel 32 extends out of the T-shaped groove and abuts against the tail of the power supply. At the same time, the limiting plate 35, under the reaction force of the telescopic sealing plate 34, presses against the front end of the power supply in the opposite direction, forming a cooperative clamping with the curved panel 32 to achieve radial limiting of the power supply. Check the fit between the power supply and the placement groove to ensure that there is no looseness.

[0042] Example 2, as follows Figure 1 , Figure 2 , Figure 3 As shown, the integrated charger 21 of the modular mechanism 2 is fixed to the outside of the power supply platform 1 by bolts. The integrated charger 21 supports synchronous and independent charging switching. Four sets of connecting plugs 22 are symmetrically connected on both sides of the integrated charger 21, and the plug ends are connected to the power socket. A wire fixing base 23 is sleeved on the outside of the connecting plug 22, which is fixed to the outside of the integrated charger 21 by bolts and is used to wrap and fix the wire part of the connecting plug 22.

[0043] Each set of connector plugs 22 is precisely connected to the lithium battery pack socket in the corresponding power supply slot; the cable holder 23 wraps around the wire part of the connector plug 22 to prevent the wire from being pulled and broken or loosened when the power is discharged later.

[0044] Example 3, as follows Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 As shown, a first gear 306 is welded to the outside of the first sleeve 301, and a gear ring 307 is welded to the bottom of the first gear 306. The gear ring 307 has the same size as the outer teeth of the first gear 306. A compensation groove 300 is opened inside the limiting plate 35, and a sliding adapter threaded column 311 is slidably fitted inside the compensation groove 300. The second gear 312 is threadedly connected to the outside of the threaded column 311. The outside of the second gear 312 meshes with the first gear 306 and the gear ring 307 respectively. The thickness of the second gear 312 is less than the thickness of the first gear 306 to prevent the second gear 312 from disengaging from the first gear 306. A first tooth groove 308 and a second tooth groove 309 are opened at the bottom of the inner cavity of the sleeve slide frame 33, which are fitted with the second gear 312 and the gear ring 307 respectively. The bottom connecting column 41 of the outer discharge mechanism 4 is welded inside the power supply placement platform 1, and a three-way plate 42 is welded to the bottom. The end of the three-way plate 42 away from the bottom connecting column 41 is welded with The built-in spring telescopic rod 43 is initially in an extended state; the bottom connecting column 41 is slidably adapted to the connecting plate 402, and the two ends of the connecting plate 402 are welded with double-pass support plates 44, the top of which abuts against the output end of the built-in spring telescopic rod 43 for limiting; the outside of the power supply platform 1 is provided with a groove, and the sliding block 46 is slidably adapted to the groove. The top of the sliding block 46 is welded with a support plate 47, the surface of which is provided with anti-slip texture to increase the friction between it and the bottom of the power supply. The outside of the sliding block 46 is welded with a connecting rope 45, the other end of which is welded to the output end of the built-in spring telescopic rod 43; the outer end face of the power supply platform 1 is welded with a guide plate 48, in which the guide plate 48 is tilted downward at 30°. At the same time, the outside of the guide plate 48 is welded with a support shaft seat 49, and the heat sink 40 is installed inside the support shaft seat 49 through a shaft rotation. The heat sink 40 has heat dissipation holes on its surface. The outside of the heat sink 40 is welded with a rocker plate 401, the top of which is pressed against the bottom of the double-pass support plate 44 for adaptation.

[0045] If an abnormally high temperature occurs during charging of a lithium battery pack, i.e., the temperature is greater than or equal to 60°C, the high temperature is conducted through the power supply front end to the melt 305 at the top of the limiting plate 35, causing the melt 305 to melt and break. The second spring 304, which was initially forcibly stretched and twisted, is released from its limiting position, then compresses and resets, accompanied by rotation. This causes the third sleeve 303 to move downwards, rotate, and retract into the second sleeve 302. The second sleeve 302 simultaneously retracts into the first sleeve 301, and finally, all three retract completely. The entire assembly is housed within the first sleeve 301. When the first sleeve 301 rotates, the first gear 306 on the outer side meshes with the second gear 312, and the second gear 312 moves downward along the threaded column 311, simultaneously meshing with the gear ring 307, causing the limiting plate 35 to move downward synchronously and retract into the sliding frame 33. Until the gear ring 307 is embedded in the second tooth groove 309 and the second gear 312 is embedded in the first tooth groove 308, the limiting plate 35 is completely housed, releasing the clamp on the power supply.

[0046] When the limiting plate 35 moves downward, it drives the telescopic rod 37 downward through the outer connecting strip 36, thereby pulling the double-through support plate 44 downward along the bottom connecting post 41, releasing the limitation on the built-in spring telescopic rod 43. Initially, when the limiting plate 35 has not moved downward, the double-through support plate 44 is at the bottom of the telescopic connection part of the built-in spring telescopic rod 43, and it squeezes its output end, causing the built-in spring telescopic rod 43 to be in an extended state, and the output end cannot be reset due to the friction and pressure of the double-through support plate 44; the retraction of the built-in spring telescopic rod 43 pulls the moving block 46 outward through the connecting rope 45, supporting The support plate 47 carries the abnormal power supply and moves synchronously. During the movement of the power supply, the socket and the connector 22 are separated by force to achieve automatic power cut-off. When the support plate 47 moves to the position of the guide plate 48, the power supply detaches from the support plate 47 under the action of inertia and slides into the guide plate 48. The inertia is generated by the spring inside the built-in spring telescopic rod 43. When it contracts, it will quickly convert the elastic potential energy into mechanical energy, so that the support plate 47 will move outward quickly. The inertial force is greater than the friction between the surface of the plate and the power supply, so that the power supply slides into the guide plate 48.

[0047] During the downward movement of the double-pass support plate 44, the rocker plate 401 is squeezed, causing the heat sink 40 to tilt upward around the shaft of the support seat 49, with the tilting angle being 45°. The power supply slides down along the guide plate 48 onto the heat sink 40, and is lifted and limited by the tilted heat sink 40. The heat dissipation holes on the surface of the heat sink 40 accelerate air circulation and passively dissipate heat from the abnormal power supply. The staff can promptly remove the abnormal power supply after heat dissipation for testing, while the other power supplies are unaffected and continue to charge normally.

[0048] The working principle of this invention is as follows: During the process of pushing the power supply to be charged into the power supply placement platform 1, the front end of the power supply forms a compression fit with the curved side of the curved panel 32, forcing the curved panel 32 to compress the first spring 31 and retract into the T-shaped groove opened on the surface of the power supply placement platform 1; when the tail of the power supply disengages from the curved side of the curved panel 32, the curved panel 32 resets and extends upward under the elastic restoring force of the first spring 31. At this time, the tail of the power supply abuts against the vertical side of the curved panel 32, and at the same time, the front end of the power supply forms a compression fit with the limiting plate 35, driving the limiting plate 35 to move into the power supply placement platform 1, and simultaneously driving the telescopic sealing plates 34 on both sides of the sliding frame 33 to undergo telescopic deformation; when the power supply is completely placed in place, the limiting plate 35 and the curved panel 32 form a cooperative clamping effect to achieve radial limiting and fixing of the power supply.

[0049] After the power supply position is fixed, the connector 22 is connected to the socket on the surface of the power supply. The integrated charger 21 can realize centralized modular charging of multiple power supplies, while each power supply can be powered independently. The cable holder 23 is used to fix the connection between the connector 22 and the integrated charger 21, effectively preventing the connection between the connector 22 and the power socket from breaking or being damaged.

[0050] When a power supply on the power supply platform 1 experiences an abnormally high temperature, the molten metal 305 welded to the top of the limiting plate 35 at the front end of the power supply melts and breaks due to heat. In the initial state, i.e., before the molten metal 305 melts, the second spring 304 is in a state of forced tension and torsion, and the limiting is achieved by the fixing effect of the molten metal 305. The first sleeve 301, the second sleeve 302, and the third sleeve 303 are all in the extended state. After the molten metal 305 melts, this balance is broken. The second spring 304 starts to reset and retract, accompanied by a torsion action. The third sleeve 303, which is connected to the top of the second spring 304, retracts synchronously into the second sleeve 302, accompanied by a rotation action. After the third sleeve 303 has completely retracted into the second sleeve 302, the second sleeve 302 further retracts into the first sleeve 301. The above retraction actions are carried out in sequence until it is completely contained in the first sleeve 301. Both sleeve 301 and sleeve 302 have T-shaped grooves on their inner walls. Sleeve 303 slides into the T-shaped groove on the inner wall of sleeve 302, and sleeve 302 slides into the T-shaped groove on the inner wall of sleeve 301. Therefore, during the resetting and retraction of spring 304, which is accompanied by torsion, sleeve 303 transmits the rotational force sequentially to sleeve 302 and sleeve 301, so that the three sleeves move in unison with spring 304, achieving synchronous retraction and rotation.

[0051] When the first sleeve 301 rotates, the first gear 306 connected to its outer side meshes with the second gear 312; the top of the second gear 312 is fixedly connected to a bearing, the inner wall of which is fixedly connected to the second gear 312, and the outer wall is fixedly connected to the bottom of the limiting plate 35. Therefore, the second gear 312 moves downward along the threaded column 311 when rotating. As the second gear 312 moves downward, it meshes with the gear ring 307, and at the same time, the limiting plate 35 moves downward synchronously and retracts into the sleeve slide frame 33. During the downward movement of the limiting plate 35, the deep groove ball bearing 30 connected to the outside of the first sleeve 301 slides along the vertical groove 38 opened on the inner wall of the limiting plate 35 via the slider 39. This sliding is relative sliding, that is, the slider 39 remains stationary, and the limiting plate 35 drives the vertical groove 38 to slide down. During the rotation and retraction of the third sleeve 303 and the second sleeve 302, the limiting plate 35 moves downward synchronously. When the third sleeve 303 and the second sleeve 302 are completely housed inside the first sleeve 301... Then, the second spring 304 continues to rotate and contract, driving the first sleeve 301, the first gear 306 and the gear ring 307 to rotate and move downward until the gear ring 307 is embedded in the second tooth groove 309, and the first sleeve 301 reaches the bottom of the inner cavity of the sleeve frame 33 and stops moving; at the same time, the second gear 312, which is meshed with the outside of the first gear 306 and the gear ring 307 respectively, moves down into the first tooth groove 308, and the limiting plate 35 is completely housed in the sleeve frame 33.

[0052] As the limiting plate 35 moves downward and is stored in the sliding frame 33, the telescopic rod 37, which is connected to the limiting plate 35 via the external connecting strip 36, moves downward synchronously. The double-pass support plate 44, which is fixedly connected to the other end of the telescopic rod 37, moves downward along the bottom connecting post 41. After the double-pass support plate 44 moves downward, it moves away from the output end of the built-in spring telescopic rod 43, releasing the limiting constraint on the built-in spring telescopic rod 43. The built-in spring telescopic rod 43 starts to retract and drives the moving block 46 to move outward via the connecting rope 45. The support plate 47 connected to the top of the moving block 46 is used to carry the power supply. Therefore, when the built-in spring telescopic rod 43 retracts, the power supply is pulled and moved outward. At the same time, the power socket and the connecting plug 22 are separated by force. When the support plate 47 moves to the position of the guide plate 48, it stops moving and uses inertia to make the power supply detach from the support plate 47 and slide into the guide plate 48.

[0053] During the downward movement of the double-pass support plate 44, the rocker plate 401 is squeezed, causing the heat sink 40 connected to the other end of the rocker plate 401 to rotate through the shaft inside the support seat 49 and tilt upward. Finally, the power supply slides down along the guide plate 48, is lifted by the tilted heat sink 40 and is limited.

[0054] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
