Description

Technical Field

[0001] This invention relates to the battery channel gate structure of a battery swapping station. Background Technology

[0002] The battery access door of the battery swapping station is set between the battery swapping position and the exchange position, which helps to isolate the battery swapping room and the charging room, improves the independence of the two, and thus enhances the safety of the battery swapping station.

[0003] As described in the existing patent document "CN220599571U A Multifunctional Battery Channel Door Structure", the door is opened by lifting and lowering the drive body to allow the battery to pass through. Currently, in battery swapping stations, batteries are moved and transported between the swapping room and the charging room by an AVG trolley. The battery is placed in the center on the AVG trolley. During transportation, the placement position may be shifted due to external vibration. After passing through the channel door and entering the charging room, if the battery is not placed in the center or is shifted, it may be difficult for the subsequent clamping mechanism to position the battery on the charging rack. Summary of the Invention

[0004] This invention addresses the technical problem of the lack of a battery channel door for guiding batteries and centering and correcting their deviation, by providing a battery channel door structure for battery swapping stations.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a battery passage door structure for a battery swapping station, including a vertically arranged guide rail and a door body slidably installed with the guide rail; the door body is connected to a lifting mechanism; it also includes: a guide plate, which is installed to the bottom of the door body via an elastic telescopic mechanism, and the bottom of the door body has a first storage groove for storing the guide plate; an elastic compression mechanism, which is connected to the elastic compression mechanism disposed inside the door body; the elastic compression mechanism provides the guide plate with a compression force to center the battery pack; the elastic compression mechanism has a compression inflation part; a dust suction mechanism, which is installed on the guide plate and is used to remove dust from the top of the battery pack passing through the guide plate; a pressing part disposed at the bottom of the elastic telescopic mechanism, which is connected to the dust suction mechanism and provides pressure for the dust suction mechanism to press against and tighten the top surface of the battery pack; the pressing part is connected to the compression inflation part and is driven by the compression inflation part.

[0006] In this technical solution, the guide plate, in conjunction with the elastic compression mechanism, provides compression force. As the battery pack passes through the bottom of the door, it is compressed and centered, correcting its position and ensuring it remains in a fixed position before flowing backward, facilitating subsequent clamping and positioning. Furthermore, the elastic telescopic mechanism and the first storage slot design allow the guide plate to retract into the first storage slot after the door closes, ensuring complete closure and preventing the bottom guide plate from interfering with normal door use. Additionally, a dust collection mechanism removes dust from the top of the battery pack after it passes the guide plate, ensuring cleanliness and preventing dust accumulation that could enter the charging port or other areas. A pressing part further compresses the dust collection mechanism against the top of the battery pack during suction, ensuring a close fit and effective suction.

[0007] Preferably, there are two guide plates, which are symmetrically arranged on both sides of the bottom of the door. A material passage for the battery pack is formed between the two guide plates, and the distance between the two ends of the material passage is greater than the distance in the middle.

[0008] In this technical solution, the battery pack passes through the material passage formed between two guide plates, with the distance gradually narrowing from the outside to the inside. This guides the battery pack to be centered in the middle position, ensuring that the battery pack flows out in a fixed position.

[0009] Preferably, the elastic telescopic mechanism includes a guide tube, a second spring, and a mounting base; the mounting base is located in the inner cavity of the door body, the mounting base has a guide hole, the guide tube is connected to the guide hole with a clearance fit, the bottom end of the guide tube is fixedly connected to the top of the guide plate, the second spring is sleeved on the guide tube, and the two ends of the second spring are fixedly connected to the mounting base and the guide plate respectively.

[0010] In this technical solution, when the door is closed, the guide plate is pressed by the ground, causing the elastic telescopic mechanism to contract and retract, thereby allowing the guide plate to be stored in the first storage slot, realizing the storage of the guide plate when the door is closed; when the door is opened, the elastic force of the elastic telescopic mechanism can drive the guide plate to extend from the first storage slot, realizing the automatic extension or automatic storage of the guide plate.

[0011] Preferably, the elastic compression mechanism includes a movable strip and a first spring disposed in the inner cavity. The movable strip is fixedly connected to the mounting base. At least one guide groove is provided on the movable strip. A guide post is connected to the guide groove with clearance fit. The guide post is fixedly installed in the inner cavity. The first spring is sleeved on the guide post. The two ends of the first spring are fixedly connected to the movable strip and the inner cavity wall, respectively.

[0012] In this technical solution, the battery pack passes through the guide plate and squeezes the guide plate, causing the first spring to compress. The first spring provides pressure to the guide plate to squeeze the battery pack and center it.

[0013] Preferably, the compression inflation part of the elastic compression mechanism includes an air cylinder fixedly installed in the inner cavity and a first piston fitted into the air cylinder; the first piston is fixedly connected to a connecting rod, the end of the connecting rod is fixedly connected to a movable bar, the air cylinder is divided into a rod chamber and a rodless chamber by the first piston, the rodless chamber is connected to a first one-way valve and a second one-way valve, the first one-way valve is connected to a fixed delivery pipe fixedly installed in the inner cavity, the end of the fixed delivery pipe away from the first one-way valve is connected to a corrugated hose, and the bottom end of the corrugated hose is connected to the top end of a guide tube.

[0014] In this technical solution, the elastic extrusion mechanism, while being extruded, also extrudes the extrusion inflation section to generate driving air pressure.

[0015] Preferably, the dust collection mechanism includes a dust inlet hood, a dust collection pipe, and a movable pipe. The dust collection pipe is fixedly installed inside the door body, and the inner wall of the dust collection pipe is connected to the outer wall of the movable pipe. At least one sealing ring is provided between the dust collection pipe and the movable pipe. The top of the dust inlet hood is fixedly connected to the bottom end of the movable pipe, and the movable pipe communicates with a cavity provided inside the dust inlet hood. The bottom of the dust inlet hood is provided with a dust inlet, and the dust inlet communicates with the cavity. Both ends of the dust inlet hood are fixedly connected with caps for sealing the ends of the cavity. A second storage slot for storing the dust inlet hood is provided at the bottom of the door body.

[0016] In this technical solution, the suction pipe is used to connect to an external vacuum cleaner. The suction pipe and the movable pipe slide together to achieve extension and retraction. This allows the dust inlet hood to be connected to the external vacuum cleaner while it is moving up and down, so that negative pressure airflow can be applied to the dust inlet hood for vacuuming.

[0017] Preferably, the pressing part includes a second piston connected to the bottom end of the guide tube and a connecting shaft fixedly installed to the bottom of the second piston. A third spring is sleeved on the connecting shaft, and the connecting shaft is elastically connected to the guide tube through the third spring. A through groove is opened on the guide plate for the end of the dust inlet hood to pass through. The bottom end of the connecting shaft extends into the through groove, and a slider is fixedly connected to the bottom end of the connecting shaft. The slider is slidably connected to a slide rail fixedly installed on the top surface of the dust inlet hood.

[0018] In this technical solution, the lower pressing part provides pressure by squeezing the air pressure generated by the inflation part to press the dust inlet cover tightly, so that the dust inlet cover fits more closely with the top surface of the battery pack, ensuring the dust suction effect.

[0019] Preferably, a pressure-limiting air intake assembly is provided at the top end of the guide tube, and a second permanent magnet is provided on one side of the pressure-limiting air intake assembly. The second permanent magnet is fixedly installed on one side wall of the inner cavity.

[0020] In this technical solution, the pressure limiting air intake component performs pressure limiting air intake, and only after the air pressure reaches a certain value can it provide air pressure to the lower pressure section.

[0021] Preferably, the pressure-limiting intake assembly includes a retaining ring fixedly installed inside the guide tube and a pressure plate disposed below the retaining ring, the top of the pressure plate being elastically connected to the inner wall of the guide tube by a fifth spring; the pressure-limiting intake assembly has an exhaust section on one side.

[0022] In this technical solution, the force of the fifth spring provides a force to press the retaining ring against the pressure plate. The pressure plate can only be opened when the air pressure is greater than the force of the fifth spring.

[0023] Preferably, the exhaust section includes a short pipe and a first permanent magnet. One end of the short pipe is fixedly connected to the guide pipe and communicates with the guide pipe. The end of the short pipe away from the guide pipe is provided with a port. One end of the first permanent magnet is located inside the port, and the diameter of the end of the first permanent magnet inside the port is smaller than the diameter of the port. The diameter of the other end of the first permanent magnet is larger than the diameter of the port, and a sealing gasket is fitted on the first permanent magnet. The first permanent magnet is elastically connected to the inner wall of the short pipe through a fourth spring. One end of the first permanent magnet is fixedly connected to a pressing block through a first connecting post, and a stop fixedly installed on the inner wall of the guide pipe is provided on one side of the pressing block. A movable block is fixedly connected to the top of the pressure plate through a second connecting post. An inclined surface is provided on one side of the movable block and the bottom of the pressing block, and the inclined surface of the movable block is in contact with the inclined surface of the pressing block.

[0024] In this technical solution, after the battery pack passes through the guide plate, the lower pressure section is reset, and the internal air pressure is released.

[0025] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0026] The positive and progressive effects of this invention are as follows: The battery channel door structure of the aforementioned battery swapping station, through the setting of guide plates and elastic compression mechanisms, allows the battery packs to pass through the bottom of the door. The elastic compression mechanism provides compression force, centering the battery packs and correcting their position. This ensures that the battery packs are in a fixed position after passing through, flowing backward for easy subsequent clamping and positioning. Furthermore, through the design of elastic telescopic mechanisms and a first storage slot, after the door closes, the elastic compression causes the telescopic mechanism to retract, allowing the guide plates to be stored in the first storage slot. This ensures the door can be completely closed, and the bottom guide plates do not affect the normal use of the door. When the door is open... Then, the guide plate extends automatically due to the elasticity of the telescopic mechanism. Furthermore, a dust-collecting mechanism is provided. After the battery pack passes through the guide plate, the dust-collecting mechanism removes dust from the top surface of the battery pack, ensuring its cleanliness and preventing dust accumulation that could enter the charging port or other locations. A pressing part is also provided. During the dust collection process, the pressing part presses the dust-collecting mechanism against the top of the battery pack, ensuring a tight fit and thus guaranteeing effective dust collection. Simultaneously, the elastic squeezing mechanism, under the mutual squeezing force of the battery pack passing through, drives the squeezing inflation part to provide air pressure for the pressing part, achieving automatic pressing without the need for other drive sources.

[0038] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0039] like Figure 1-10As shown, the battery swapping station's battery access door structure includes a vertically arranged guide rail 1 and a door body 2 slidably installed with the guide rail 1; the door body 2 is connected to a lifting mechanism, wherein the lifting mechanism has various sophisticated technical means in the prior art, such as electric push rods, cylinders, and linear modules, etc., which will not be described in detail in this application; it also includes: a guide plate 3, the guide plate 3 is installed to the bottom of the door body 2 through an elastic telescopic mechanism 6, and the bottom of the door body 2 has a first storage groove 201 for storing the guide plate 3; an elastic compression mechanism 5, the elastic telescopic mechanism 6 and An elastic compression mechanism 5 is connected inside the door body 2; the elastic compression mechanism 5 provides the guide plate 3 with the compression force to center the battery pack 9; the elastic compression mechanism 5 has a compression inflation part; a dust suction mechanism 4 is installed on the guide plate 3 to remove dust from the top of the battery pack 9 passing through the guide plate 3; a pressing part is provided at the bottom of the elastic telescopic mechanism 6, the pressing part is connected to the dust suction mechanism 4, and provides pressure for the dust suction mechanism 4 to press against the top surface of the battery pack 9; the pressing part is connected to the compression inflation part and is driven by the compression inflation part.

[0040] In practical implementation, through the setting of guide plate 3 and elastic compression mechanism 5, as the battery pack 9 passes through the bottom of door 2, the elastic compression mechanism 5 provides compression force, which can center the battery pack 9 and correct its position. Furthermore, through the design of elastic telescopic mechanism 6 and first storage slot 201, after door 2 is lowered and closed, elastic compression causes elastic telescopic mechanism 6 to retract, thereby allowing guide plate 3 to be stored in the first storage slot 201, ensuring that door 2 can be completely closed, and the bottom guide plate... 3 will not affect the normal use of door 2. After door 2 is opened, guide plate 3 will automatically extend through the elastic force of elastic telescopic mechanism 6. Furthermore, a vacuuming mechanism 4 is provided. After the battery pack 9 passes through guide plate 3, the vacuuming mechanism 4 is used to remove dust from the top surface of battery pack 9, ensuring the cleanliness of the top surface of battery pack 9. A pressing part is also provided. During the vacuuming process of battery pack 9, the pressing part presses the vacuuming mechanism 4 to the top of battery pack 9, ensuring a tight fit during vacuuming, thereby ensuring the vacuuming effect.

[0041] like Figure 1 and Figure 10 As shown, there are two guide plates 3, and the two guide plates 3 are symmetrically arranged on both sides of the bottom of the door body 2. A material passage groove for the battery pack 9 to pass through is formed between the two guide plates 3, and the distance between the two ends of the material passage groove is greater than the distance in the middle.

[0042] A material passage chute, with its spacing gradually narrowing from the outside to the inside, is formed between two guide plates 3. The battery pack 9 passes through the chute, achieving guidance and centering it towards the middle position for position correction. This ensures the battery pack 9 flows out in a fixed position to the next workstation, facilitating clamping or gas manipulation. Figure 10 As shown, the width of the battery pack 9 is greater than the spacing at the narrowest point of the feed trough. When passing through the feed trough, the two guide plates 3 are spread apart, causing the elastic extrusion mechanism 5 to undergo elastic deformation.

[0043] like Figure 2 As shown, as a specific technical solution, the elastic telescopic mechanism 6 includes a guide tube 601, a second spring 602, and a mounting base 603; the mounting base 603 is located in the inner cavity 202 inside the door body 2, and a guide hole 6031 is provided on the mounting base 603. The guide tube 601 is connected to the guide hole 6031 with a clearance fit. The bottom end of the guide tube 601 is fixedly connected to the top of the guide plate 3. The second spring 602 is sleeved on the guide tube 601, and the two ends of the second spring 602 are fixedly connected to the mounting base 603 and the guide plate 3, respectively.

[0044] in Figure 2 In this design, the guide plate 3 extends from the first storage slot 201. After the door 2 is closed, the guide plate 3 is retracted into the first storage slot 201 by the pressure of the ground. At the same time, the guide tube 601 moves with the guide plate 3, providing guidance through the guide hole 6031, and compressing the second spring 602 to produce compression deformation. When the door 2 is opened, the bottom of the guide plate 3 is no longer obstructed. Through the elastic force of the second spring 602, the guide tube 601 and the guide plate 3 are driven downward together, leaving the first storage slot 201 and extending out. Through this design, the guide plate 3 is automatically retracted when the door 2 is closed, without affecting the closing of the door 2. When the door 2 is opened, it automatically extends to provide guidance and centering for the passing battery pack 9. Furthermore, the extension and retraction of the guide plate 3 can be achieved without an additional power source, simply through the elastic extension and retraction of the elastic extension mechanism 6.

[0045] like Figure 2-3 As shown, as a specific technical solution, the elastic compression mechanism 5 includes a movable strip 507 and a first spring 509 disposed in the inner cavity 202. The movable strip 507 is fixedly connected to the mounting base 603. At least one guide groove 510 is provided on the movable strip 507. A guide post 508 is connected to the guide groove 510 with clearance fit. The guide post 508 is fixedly installed in the inner cavity 202. The first spring 509 is sleeved on the guide post 508. The two ends of the first spring 509 are fixedly connected to the movable strip 507 and the wall of the inner cavity 202, respectively.

[0046] When the battery pack 9 passes between the two guide plates 3, the width of the section it passes through is less than the width of the battery pack 9. The guide plates 3 are then spread apart to increase the distance between the two guide plates 3 until the battery pack 9 moves to the narrowest position of the feed chute, at which point the narrowest position is spread apart to the width of the battery pack 9, thus centering the battery pack 9. During the above process, the movement of the guide plates 3 drives the mounting base 603 and the movable bar 507 to move through the guide tube 601, compressing the first spring 509. At the same time, the movement of the movable bar 507 is guided by the guide post 508 and the guide groove 510, ensuring the stability of the movement.

[0047] like Figure 3 As shown, as a specific technical solution, the compression inflation part of the elastic compression mechanism 5 includes an air cylinder 502 fixedly installed in the inner cavity 202 and a first piston 505 fitted inside the air cylinder 502; the first piston 505 is fixedly connected to a connecting rod 506, the end of the connecting rod 506 is fixedly connected to a movable bar 507, the air cylinder 502 is divided into a rod chamber and a rodless chamber by the first piston 505, the rodless chamber is connected to a first one-way valve 503 and a second one-way valve 504, the first one-way valve 503 is connected to a fixed delivery pipe 501 fixedly installed in the inner cavity 202, the end of the fixed delivery pipe 501 away from the first one-way valve 503 is connected to a corrugated hose 511, the bottom end of the corrugated hose 511 is connected to the top end of the guide pipe 601.

[0048] During the compression of the first spring 509 by the movable bar 507, the connecting rod 506 moves together with the movable bar 507, pressurizing the gas in the rodless chamber through the first piston 505. Through the first one-way valve 503, the air pressure is applied to the guide tube 601 through the fixed delivery pipe 501 and the corrugated hose 511. The corrugated hose 511 is a hose structure with a corrugated surface to prevent expansion and contraction, so that while applying air pressure to the guide tube 601, it does not affect the up-down and left-right movement of the guide tube 601.

[0049] like Figure 2 , Figure 4 as well as Figure 7As shown, as a specific technical solution, the vacuuming mechanism 4 includes a dust inlet hood 403, a vacuum pipe 401, and a movable pipe 402. The vacuum pipe 401 is fixedly installed inside the door body 2. The inner wall of the vacuum pipe 401 is connected to the outer wall of the movable pipe 402, and at least one sealing ring is provided between the vacuum pipe 401 and the movable pipe 402. The top of the dust inlet hood 403 is fixedly connected to the bottom end of the movable pipe 402, and the movable pipe 402 communicates with the cavity 4031 provided inside the dust inlet hood 403. The bottom of the dust inlet hood 403 is provided with a dust inlet 4032, and the dust inlet 4032 communicates with the cavity 4031. Both ends of the dust inlet hood 403 are fixedly connected with caps 4033 for sealing the ends of the cavity 4031. The bottom of the door body 2 is provided with a second storage groove 203 for storing the dust inlet hood 403.

[0050] The suction pipe 401 is used to connect to external vacuuming equipment, such as the suction port of an industrial vacuum cleaner. When the guide plate 3 moves up and down, the dust inlet hood 403 will move up and down with the guide plate 3. The movable pipe 402 can slide vertically along the suction pipe 401. While not affecting its up and down movement, it can also connect the suction pipe 401 and the dust inlet hood 403. The sealing ring design ensures the sealing of the connection. The sealing ring can be a rubber sealing ring. The design of the second storage groove 203 is used so that after the guide plate 3 is stored in the first storage groove 201, the corresponding dust inlet hood 403 can be stored in the second storage groove 203.

[0051] The suction pipe 401 generates negative pressure through the suction device, which is then applied to the dust inlet 4032 via the movable pipe 402 and the cavity 4031. When the top surface of the battery pack 9 is attached to the dust inlet 4032, dust can be sucked away.

[0052] like Figure 7 As shown, in a specific implementation, the pressing part includes a second piston 605 connected to the bottom end of the guide tube 601 and a connecting shaft 604 fixedly installed to the bottom of the second piston 605. A third spring 606 is sleeved on the connecting shaft 604, and the connecting shaft 604 is elastically connected to the guide tube 601 through the third spring 606. The guide plate 3 has a through groove 301 for the end of the dust inlet hood 403 to pass through. The bottom end of the connecting shaft 604 extends into the through groove 301, and a slider 4035 is fixedly connected to the bottom end of the connecting shaft 604. The slider 4035 is slidably connected to a slide rail 4034 fixedly installed on the top surface of the dust inlet hood 403. While the slide rail 4034 and the slider 4035 can slide, the cross section of the slider 4035 adopts an isosceles trapezoidal structure. The slide rail 4034 and the slider 4035 are adapted to each other, which plays a role in preventing the slide rail 4034 and the slider 4035 from vertically separating.

[0053] When the air pressure in the guide tube 601 acts on the top surface of the second piston 605, it drives the connecting shaft 604 to move downward. The connecting shaft 604, through the slider 4035 and the slide rail 4034, causes the dust inlet hood 403 to move downward and press against the top surface of the battery pack 9. This creates a certain pressure between the battery pack 9 and the dust inlet 4032, causing them to press tightly together. At the same time, it stretches the third spring 606, causing tensile deformation.

[0054] During the process of the guide plate 3 opening and widening the material passage, the slider 4035 and the slide rail 4034 can slide relative to each other. The dust inlet hood 403 is installed on the guide plate 3 and will not affect its opening.

[0055] like Figure 2 , Figure 5 , Figure 6 , Figure 8 as well as Figure 9 As shown, as a specific technical solution, a pressure-limiting air intake assembly 7 is provided at the top of the guide tube 601. A second permanent magnet 8 is provided on one side of the pressure-limiting air intake assembly 7, and the second permanent magnet 8 is fixedly installed on one side wall of the inner cavity 202. The pressure-limiting air intake assembly 7 includes a retaining ring 709 fixedly installed inside the guide tube 601 and a pressure plate 710 provided below the retaining ring 709. The top of the pressure plate 710 is elastically connected to the inner wall of the guide tube 601 through a fifth spring 708. One side of the pressure-limiting air intake assembly 7 has an exhaust section. The exhaust section includes a short pipe 701 and a first permanent magnet 702. One end of the short pipe 701 is fixedly connected to the guide tube 601 and communicates with the guide tube 601. The end of the short pipe 701 away from the guide tube 601 is provided with a port. One end of the first permanent magnet 702 is disposed inside the port, and the diameter of the end of the first permanent magnet 702 inside the port is smaller than the diameter of the port. The diameter of the other end of the first permanent magnet 702 is larger than the diameter of the port. A sealing gasket 703 is fitted on the first permanent magnet 702. The first permanent magnet 702 is elastically connected to the inner wall of the short tube 701 through a fourth spring 704. One end of the first permanent magnet 702 is fixedly connected to a pressing block 706 through a first connecting post 705. A stop 707 is fixedly installed on the inner wall of the guide tube 601 on one side of the pressing block 706. A movable block 712 is fixedly connected to the top of the pressure plate 710 through a second connecting post 711. An inclined surface is provided on one side of the movable block 712 and the bottom of the pressing block 706. The inclined surface of the movable block 712 is in contact with the inclined surface of the pressing block 706.

[0056] The fifth spring 708 is in a stretched state, providing the pressure plate 710 with the force to press the retaining ring 709. The pressure plate 710 can only open when the air pressure is greater than the elastic force of the fifth spring 708. When the air pressure is less than the elastic force of the fifth spring 708, it is closed, and the air pressure cannot act on the second piston 605. When one end of the battery pack 9 moves below the dust inlet hood 403, the air pressure increases to a level greater than the elastic force of the fifth spring 708, causing the pressure plate 710 to move downward, opening the retaining ring 709. The air pressure can then act on the second piston 605, driving the dust inlet hood 403 downward and pressing it down onto the battery pack. On the 9th surface, the through groove 301 provides sufficient downward space and will not affect the downward movement of the dust inlet hood 403. The design of pressing the hood 403 only after the battery pack 9 moves above it prevents the dust inlet hood 403 from moving downwards prematurely without the obstruction of the battery pack 9, which would cause the dust inlet hood 403 to move too far downwards and thus obstruct the battery pack 9. Compared with the dust inlet hoods with a fixed height in traditional technology, the dust inlet hood needs to maintain a certain gap with the top surface of the battery pack 9 in order to allow the battery pack 9 to pass through normally. The dust inlet hood and the battery pack 9 do not fit well enough, which affects the dust collection effect.

[0057] When the battery pack 9 enters the narrowest position of the guide plate 3, the guide plate 3 is opened to its maximum. After the rodless chamber in the air cylinder 502 is compressed to its maximum value, the air pressure cannot continue to increase. During the process of the battery pack 9 passing through the narrowest position, the air pressure does not increase. After the air pressure increases to its maximum value, the air pressure on both sides of the pressure plate 710 gradually becomes equal. Before the battery pack 9 completely leaves the guide plate 3, the pressure plate 710 has already been sealed by the retaining ring 709. After the battery pack 9 completely passes through the guide plate 3, the guide plate 3 loses the squeezing force of the battery pack 9. Through the elastic force of the first spring 509, the guide plate 3 and the movable bar 507 are reset. The movable bar 507 drives the connecting rod 506 to reset, driving the first piston 505 to pump air and reduce the air pressure in the rodless chamber. At this time, external air is allowed to enter through the second one-way valve 504 to compensate for the air that cannot return to the rodless chamber below the pressure plate 710, so that the air cylinder 502 returns to atmospheric pressure.

[0058] After the battery pack 9 passes through, the door 2 descends. Due to the pressure from the ground, the guide plate 3 retracts into the first storage slot 201. Simultaneously, the guide tube 601 moves along with it. After the door 2 is fully closed, the guide plate 3 is fully retracted. At this point, the first permanent magnet 702 of the limiting air intake assembly aligns with the second permanent magnet 8. The opposite ends of the first permanent magnet 702 and the second permanent magnet 8 have the same magnetic poles. Therefore, the second permanent magnet 8 provides a repulsive force to the first permanent magnet 702, causing the first permanent magnet 702 to move towards the short end. The internal movement of pipe 701 opens the port, compresses the fourth spring 704, and drives the extrusion block 706 to move via the first connecting post 705. The extrusion block 706 extrudes the movable block 712, causing the movable block 712 to move downward. The movable block 712 drives the pressure plate 710 downward via the second connecting post 711, opening the retaining ring 709 and increasing the tension of the fifth spring 708. The stop seat 707 is used to block the movement of the extrusion block 706. During the above process, the state of the pressure limiting air intake assembly 7 changes from... Figure 8 Transformation to Figure 9 This causes the retaining ring 709 to open and the short pipe 701 to open, allowing the gas below the pressure plate 710 to pass through the retaining ring 709 and be discharged through the short pipe 701, restoring atmospheric pressure. In the subsequent process where the next battery pack 9 needs to pass through, the door 2 opens and the guide plate 3 extends, separating the first permanent magnet 702 from the second permanent magnet 8. Through the elastic force of the fourth spring 704 and the fifth spring 708, the pressure plate 710 can re-seal the retaining ring 709, and the first permanent magnet 702 can seal the port of the short pipe 701 through the sealing gasket 703.
