A battery compartment box body is boltedly connected to one side of the parking box body. A movable side plate is arranged on the side, away from the parking box body, of the battery compartment box body. An extension bottom plate, which is slidably connected to the battery compartment box body and the parking box body respectively, is welded to the side, close to the battery compartment box body, of the bottom of the movable side plate.

Description

Technical Field

[0001] This invention belongs to the field of new energy battery swapping station technology, and specifically relates to a new energy battery swapping station housing with a foldable extended assembly structure. Background Technology

[0002] As an important component of electric vehicle energy replenishment infrastructure, the space utilization and adaptability of the battery compartment of a new energy battery swapping station directly affect the battery swapping efficiency and site layout.

[0003] Currently, most battery swapping station enclosures are fixed structures, with the battery compartment volume determined at the factory and unable to be flexibly adjusted according to fluctuations in swapping demand. However, the swapping demand of new energy battery swapping stations in different regions often varies. When the demand for swapping at a certain station is high, the fixed-capacity battery compartment is insufficient to store a sufficient number of spare batteries, resulting in insufficient swapping capacity; while when the demand is low, it leads to idle space and wasted equipment space.

[0004] In existing technologies, when it is necessary to increase battery storage capacity, traditional solutions often require replacing the entire battery compartment or additionally splicing new compartment modules, which results in long construction cycles and high costs. More importantly, they place high demands on the existing site space. For example, when adding new capacity-expanding compartments, a sufficiently large open space must be reserved on one side or behind the original site to accommodate the new compartments. This open space not only needs to match the size of the new compartments but also needs to ensure that transport vehicles and hoisting equipment can enter and operate. Therefore, the reserved open space is often much larger than the size of the added compartments, which takes up a lot of public space and is therefore not practical overall. Summary of the Invention

[0005] The purpose of this invention is to provide a battery swapping station enclosure with a foldable expandable assembly structure. Its advantages are that the internal space of the battery compartment can be expanded according to the battery swapping needs of the new energy battery swapping station, thereby improving the site utilization rate of the battery swapping station; at the same time, it ensures that the battery compartment can still maintain good ventilation and heat dissipation after the new energy battery swapping station has been used for a long time.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a new energy battery swapping station housing with a foldable expansion assembly structure, including a parking housing, a battery compartment housing bolted to one side of the parking housing, a movable side plate provided on the side of the battery compartment housing away from the parking housing, an extension bottom plate welded to the bottom of the movable side plate near the battery compartment housing and slidably connected to the battery compartment housing and the parking housing respectively, a protective shell bolted to the top of the movable side plate away from the battery compartment housing, and a battery compartment folding expansion mechanism and a battery compartment ventilation mechanism respectively provided inside the battery compartment housing and the protective shell for use in conjunction with the movable side plate.

[0007] The invention is further configured such that the battery compartment folding and expansion mechanism includes a first motor bolted to one side of the inner surface of the protective housing; the output end of the first motor is bolted to a positive and negative threaded rod rotatably connected to the protective housing; a fixing rod is bolted to the top of the inner cavity of the battery compartment; a baffle is fixedly sleeved at the center of the surfaces of the positive and negative threaded rod and the fixing rod; a first threaded rod sleeve is threaded on both sides of the positive and negative threaded rod at the baffle; the threads on both sides of the positive and negative threaded rod are in opposite directions; a sliding sleeve is slidably sleeved on both sides of the fixing rod at the baffle; a rotating seat is bolted to the side of the two first threaded rod sleeves and the two sliding sleeves that are close to each other; two cross-arranged support arms are rotatably connected between the four rotating seats; and the center points of the two support arms are rotatably connected to each other.

[0008] Using the above technical solution: Since the threads on both sides of the positive and negative threaded rods are opposite, when the first motor drives the positive and negative threaded rods to rotate in one direction, the two first threaded rod sleeves can slide closer to each other or further away from each other, thereby driving the support arms to rotate crosswise to support the movable side plate to slide away from the battery compartment box for expansion.

[0009] The invention is further configured such that the battery compartment folding and expansion mechanism includes a sliding frame disposed between the battery compartment body and the movable side panel. The two sides of the sliding frame and the side of the battery compartment body and the movable side panel that are close to each other are sealed and bonded with composite tarpaulin. The top and two sides of the sliding frame, the battery compartment body and the movable side panel are bolted with rotating shafts. The top and two sides of the composite tarpaulin are provided with cross-shaped outer support arms. The two ends of the outer support arms are rotatably connected to the rotating shafts.

[0010] The above technical solution is adopted: when the movable side panel slides outward and expands, the outer support arm can be rotated and opened through the rotating shaft. It can not only support the sliding frame and composite tarpaulin, so that the sliding frame and composite tarpaulin will not deform when expanding and folding, but also form a mesh structure after the outer support arm is rotated and opened, thereby protecting the relatively soft composite tarpaulin.

[0011] The present invention is further configured such that the battery compartment ventilation mechanism includes a second motor bolted to the side of the movable side plate near the battery compartment housing, the output end of the second motor is bolted to a first one-way overrunning clutch, the end of the first one-way overrunning clutch away from the second motor is bolted to an exhaust fan rotatably connected to the movable side plate, and both sides of the battery compartment housing are provided with air inlet slots for use in conjunction with the exhaust fan, and the interior of both air inlet slots is bolted with a protective net.

[0012] The above technical solution involves turning on the second motor to drive the exhaust fan to rotate, blowing the gas inside the battery compartment outwards, allowing the air inside the battery compartment to circulate, thereby ventilating and dissipating heat inside the battery compartment.

[0013] The invention is further configured such that a C-shaped cylinder is bolted to the inside of the air inlet chute on the side of the protective net away from the inside of the battery compartment, a reciprocating screw is rotatably connected to the battery compartment through the inside of the C-shaped cylinder, a second screw sleeve is slidably connected to the C-shaped cylinder and threaded onto the surface of the reciprocating screw, and a brush plate is bolted to the side of the second screw sleeve near the protective net, a rotating cylinder is rotatably connected to the top of the air inlet chute inside the battery compartment, and meshing bevel gears are bolted to the top of the reciprocating screw and the surface of the rotating cylinder.

[0014] The above technical solution is adopted because when the exhaust fan rotates and blows air outward, outside air will enter through the protective net on the side away from the inside of the battery compartment. Therefore, dust accumulates on this side, and the brush plate is also located on this side, which can effectively clean the dust off the surface of the protective net.

[0015] The invention is further configured such that a rotating rod is rotatably connected to the top of the movable side plate near the rotating cylinder; a polygonal insert rod is welded to one end of the rotating rod near the battery compartment housing and slidably connected to the interior of the rotating cylinder; the end of the rotating cylinder away from the polygonal insert rod is rotatably connected to the interior of the parking box; a second one-way overrunning clutch is bolted to the end of the rotating rod away from the polygonal insert rod and rotatably connected to the movable side plate; a synchronous pulley is fixedly sleeved on the output end of the second motor and the end of the second one-way overrunning clutch away from the rotating rod; and a synchronous belt is drivenly sleeved on the surfaces of the two synchronous pulleys.

[0016] Using the above technical solution: Since the exhaust fan and the rotating rod are connected to the output end of the second motor in one-way transmission through the first one-way overrunning clutch and the second one-way overrunning clutch respectively, when the second motor is turned on to rotate in the forward direction, only the exhaust fan will rotate, and the second one-way overrunning clutch will idle; while when the second motor is turned on to rotate in the reverse direction, only the rotating rod will rotate through the second one-way overrunning clutch, and the first one-way overrunning clutch will idle.

[0017] The present invention is further configured such that sealing gaskets are adhered to both sides of the extended base plate, and the two sides of the extended base plate are slidably connected to the sliding frame through the sealing gaskets.

[0018] The above technical solution improves the sealing between the extension base plate and the sliding frame without affecting the normal sliding of the extension base plate.

[0019] The invention is further configured such that rollers are rotatably connected to both sides of the bottom of the movable side plate.

[0020] The above technical solution supports the sliding of the movable side plate to both sides while reducing friction during sliding.

[0021] The invention is further configured such that a movable door panel is bolted to the side of the parking box near the battery compartment.

[0022] Using the above technical solution: the interior of the parking compartment can be connected to the interior of the battery compartment by opening the movable door panel, which facilitates the storage and retrieval of batteries for battery swapping.

[0023] The present invention is further configured such that both sides of the battery compartment are bolted with detachable louvers that cooperate with the air inlet slots, and the movable side plate away from the battery compartment is bolted with an air outlet mesh plate that cooperates with the exhaust fan.

[0024] The above technical solution is adopted: the air intake end of the support arm can be protected by a detachable louver to prevent water droplets from being sucked into the interior during air intake; at the same time, the exhaust end of the exhaust fan is protected by an exhaust mesh plate to prevent external dust and impurities from entering the battery compartment when the exhaust fan stops rotating and blowing air.

[0025] In summary, the present invention has the following beneficial effects: 1. By setting up a battery compartment folding and expansion mechanism, the internal space of the battery compartment on one side of the new energy battery swapping station can be expanded and folded, so that the size of the internal space of the battery compartment can be adjusted according to the actual needs of the new energy battery swapping station. When the battery swapping demand of this new energy battery swapping station is frequent, the internal space of the battery compartment can be expanded to store more battery modules to ensure the battery swapping demand. Conversely, when the battery swapping demand of this new energy battery swapping station is less, the internal space of the battery compartment can be folded back to reduce the area occupied by the new energy battery swapping station and significantly improve the site utilization rate of the battery swapping station. 2. By installing a battery compartment ventilation mechanism inside the battery compartment housing and movable side panels, the internal structure of the battery compartment can be ventilated and cooled to ensure that the temperature of the battery modules stored inside the battery compartment is normal. Secondly, the surface of the air inlet filter screen can be cleaned to remove accumulated dust, ensuring smooth airflow inside the battery compartment housing. Even if the internal space of the battery compartment housing is expanded, it will not affect the cleaning of the filter screen surface, thus ensuring that the new energy battery swapping station can maintain good ventilation and heat dissipation effect even after long-term use.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10A new energy battery swapping station enclosure with a foldable expansion assembly structure includes a parking enclosure 1. A battery compartment enclosure 2 is bolted to one side of the parking enclosure 1. A movable side plate 3 is provided on the side of the battery compartment enclosure 2 away from the parking enclosure 1. An extension bottom plate 8, which is slidably connected to both the battery compartment enclosure 2 and the parking enclosure 1, is welded to the bottom of the movable side plate 3 near the battery compartment enclosure 2. A protective shell 4 is bolted to the top of the movable side plate 3 away from the battery compartment enclosure 2. A battery compartment folding expansion mechanism 5, which works in conjunction with the movable side plate 3, is provided inside both the battery compartment enclosure 2 and the protective shell 4. By providing the battery compartment folding expansion mechanism 5, the internal space of the battery compartment enclosure 2 on one side of the new energy battery swapping station can be expanded. The folding mechanism allows for adjustment of the internal space of the battery compartment 2 according to the actual needs of the new energy battery swapping station. When the battery swapping demand is frequent, the internal space of the battery compartment 2 can be expanded to store more battery modules to ensure the battery swapping needs are met. Conversely, when the battery swapping demand is low, the internal space of the battery compartment 2 can be folded back to reduce the area occupied by the new energy battery swapping station, significantly improving the site utilization rate of the swapping station. The extension base plate 8 is made of rolled high-strength steel with a thickness of not less than 10mm, and its lower surface is welded with "well"-shaped or longitudinally interlaced reinforcing ribs to improve the load-bearing capacity of the extension base plate 8 and ensure that no plastic deformation occurs during long-term use.

[0030] refer to Figure 2 , Figure 3 , Figure 4 The battery compartment folding and expansion mechanism 5 includes a first motor 501 bolted to one side of the inner surface of the protective housing 4. The output end of the first motor 501 is bolted to a threaded rod 502 rotatably connected to the protective housing 4. A fixing rod 505 is bolted to the top of the inner cavity of the battery compartment 2. A baffle 503 is fixedly sleeved at the center of the surfaces of both the threaded rod 502 and the fixing rod 505. First threaded rod sleeves 504 are threaded onto both sides of the threaded rod 502 on the baffle 503. The threads on both sides of the threaded rod 502 are in opposite directions. The fixing rod 505 is slidably sleeved onto both sides of the baffle 503. The sliding sleeve 506, the two first lead screw sleeves 504, and the two sliding sleeves 506 are all bolted to the side of each other. The four rotating seats 507 are rotatably connected to each other by two cross-arranged support arms 508. The center points of the two support arms 508 are rotatably connected to each other. Since the threads on both sides of the positive and negative threaded screws 502 are opposite, when the first motor 501 drives the positive and negative threaded screws 502 to rotate in one direction, the two first lead screw sleeves 504 can slide closer to each other or further away from each other, thereby driving the support arms 508 to rotate cross-arrangedly to support the movable side plate 3 to slide away from the battery compartment box 2 for expansion.

[0031] refer to Figure 1 , Figure 2 , Figure 10 The battery compartment folding and expansion mechanism 5 also includes a sliding frame 509 disposed between the battery compartment body 2 and the movable side panel 3. Composite tarpaulin 510 is sealed and bonded to both sides of the sliding frame 509 and the sides of the battery compartment body 2 and the movable side panel 3 that are close to each other. Rotating shafts 511 are bolted to the top and both sides of the sliding frame 509, the battery compartment body 2, and the movable side panel 3. Outer support arms 512 are cross-arranged on the top and both sides of the composite tarpaulin 510, and both ends of the outer support arms 512 are rotatably connected to the rotating shafts 511. When the movable side panel 3 slides outward to expand, the outer support arms 512 can be rotated open via the rotating shafts 511. It can not only support the sliding frame 509 and the composite tarpaulin 510, preventing them from deforming during expansion and folding, but also form a mesh structure when the outer support arm 512 is rotated open, thus protecting the relatively soft composite tarpaulin 510. The composite tarpaulin 510 is made of PVC-coated polyester fiber cloth and TPU-coated nylon cloth. All seams are sealed with high-frequency heat sealing, and rubber sealing strips are also inserted at the connecting edges to form an airtight connection. This not only ensures airtightness, but also provides the composite tarpaulin 510 with a certain degree of protection, making it less prone to damage even after long-term use.

[0032] refer to Figure 2 , Figure 3 Both sides of the extended base plate 8 are bonded with sealing gaskets 9, and the two sides of the extended base plate 8 are slidably connected to the sliding frame 509 through the sealing gaskets 9; this improves the sealing performance between the extended base plate 8 and the sliding frame 509, while not affecting the normal sliding of the extended base plate 8.

[0033] refer to Figure 1 , Figure 2 Rollers 7 are rotatably connected to both sides of the bottom of the movable side plate 3; they support the movable side plate 3 to slide to both sides and reduce the friction during sliding.

[0034] Brief description of the usage process: By turning on the first motor 501, the positive and negative threaded rods 502 are rotated inside the protective housing 4, so that the positive and negative threaded rods 502 are threadedly engaged with the first threaded rod sleeves 504 on both sides of the surface, thereby causing the two first threaded rod sleeves 504 to slide closer to each other, so that the two first threaded rod sleeves 504 drive the two support arms 508 to be limited through the center point and rotate crosswise; the other end of the two support arms 508 away from the first threaded rod sleeves 504 is supported by two sliding sleeves 506 sliding on the surface of the fixed rod 505, and at the same time, the two ends of the two sliding sleeves 506 are rotatably connected to the first threaded rod sleeves 504 and the sliding sleeves 506 respectively through the rotating seat 507; thus, after the two first threaded rod sleeves 504 drive the two sliding sleeves 506 to rotate crosswise, they can push the movable side plate 3 away from the battery compartment box 2 and cause the extended bottom plate 8 at the bottom of the movable side plate 3 to slide outward at the bottom of the battery compartment box 2 to expand the internal space of the battery compartment box 2. Furthermore, when the movable side panel 3 slides away from the battery compartment housing 2, the sliding frame 509 and the composite tarpaulin 510 can be pulled to unfold, sealing and covering the space expanded between the battery compartment housing 2 and the movable side panel 3. The outer support arms 512 on both sides of the top of the composite tarpaulin 510 can be rotated and opened by the rotating shaft 511, forming a mesh structure that can protect the space expanded between the battery compartment housing 2 and the movable side panel 3. When the first motor 501 is turned on to drive the positive and negative threaded rods 502 to rotate in opposite directions, the two first threaded rod sleeves 504 will slide away from each other, causing the two ends of the two sliding sleeves 506 to rotate in opposite directions, thereby driving the movable side panel 3 to slide closer to the battery compartment housing 2. The soft composite tarpaulin 510 between the sliding frames 509 can be bent and stacked together, and the outer support arms 512 can also be rotated and folded together by the rotating shaft 511, thereby shrinking the space inside the battery compartment housing 2, so that the space inside the battery compartment housing 2 can be adjusted as needed.

[0035] Example 2: refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9This embodiment extends from embodiment 1. The battery compartment housing 2 and the protective shell 4 are respectively equipped with a battery compartment ventilation mechanism 6 that works in conjunction with the movable side plate 3. The battery compartment ventilation mechanism 6 includes a second motor 601 bolted to the side of the movable side plate 3 closest to the battery compartment housing 2. A first one-way overrunning clutch 602 is bolted to the output end of the second motor 601. An exhaust fan 603, rotatably connected to the movable side plate 3, is bolted to the end of the first one-way overrunning clutch 602 away from the second motor 601. Air inlet slots 608, which work in conjunction with the exhaust fan 603, are provided on both sides of the battery compartment housing 2. Protective nets 609 are bolted to the interior of each of the two air inlet slots 608. By turning on the second motor 601 to drive the exhaust fan 603 to rotate, the gas inside the battery compartment housing 2 is blown outwards, allowing the air inside the battery compartment housing 2 to circulate, thereby ventilating and dissipating heat inside the battery compartment housing 2.

[0036] refer to Figure 3 , Figure 6 , Figure 7 , Figure 9 A C-shaped cylinder 610, bolted to the inside of the air inlet chute 608, is provided on the side of the protective net 609 away from the inside of the battery compartment housing 2. A reciprocating screw 611, rotatably connected to the battery compartment housing 2, is installed through the inside of the C-shaped cylinder 610. A second screw sleeve 612, slidably connected to the C-shaped cylinder 610, is threaded onto the surface of the reciprocating screw 611. A brush plate 613 is bolted to the side of the second screw sleeve 612 closest to the protective net 609. A rotating cylinder 615 is rotatably connected to the top of the air inlet chute 608 inside the battery compartment housing 2. Meshing bevel gears 614 are bolted to the top of the reciprocating screw 611 and the surface of the rotating cylinder 615. When the exhaust fan 603 rotates and blows air outward, outside air enters through the side of the protective net 609 away from the inside of the battery compartment housing 2, so dust accumulates on this side. The brush plate 613 is also located on this side, which can effectively clean the dust off the surface of the protective net 609.

[0037] refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9A rotating rod 604 is rotatably connected to the top of the movable side plate 3 near the rotating cylinder 615. A polygonal insert 616, which is slidably connected to the inside of the rotating cylinder 615, is welded to the end of the rotating rod 604 near the battery compartment 2. The end of the rotating cylinder 615 away from the polygonal insert 616 is rotatably connected to the inside of the parking box 1. A second one-way overrunning clutch 605, which is rotatably connected to the movable side plate 3, is bolted to the end of the rotating rod 604 away from the polygonal insert 616. The output end of the second motor 601 and the end of the second one-way overrunning clutch 605 away from the rotating rod 604 are both fixedly sleeved with the same... The step wheel 606 and the two synchronous pulleys 606 are connected to the surface of the synchronous belt 607. Since the exhaust fan 603 and the rotating rod 604 are connected to the output end of the second motor 601 through the first one-way overrunning clutch 602 and the second one-way overrunning clutch 605 respectively, when the second motor 601 is turned on to rotate in the forward direction, only the exhaust fan 603 will be driven to rotate, and the second one-way overrunning clutch 605 will rotate freely. When the second motor 601 is turned on to rotate in the reverse direction, only the rotating rod 604 will be driven to rotate through the second one-way overrunning clutch 605, and the first one-way overrunning clutch 602 will rotate freely.

[0038] refer to Figure 2 , Figure 3 , Figure 6 The parking box 1 has a movable door panel 10 bolted to the side of the battery compartment box 2. The interior of the parking box 1 can be connected to the interior of the battery compartment box 2 by opening the movable door panel 10, which facilitates the storage and retrieval of batteries for battery swapping.

[0039] refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 Both sides of the battery compartment housing 2 are bolted with detachable louvers 11 that work in conjunction with the air inlet sloping channel 608. The movable side plate 3, on the side away from the battery compartment housing 2, is bolted with an air outlet mesh plate 12 that works in conjunction with the exhaust fan 603. The air inlet sloping channel 608 is the air inlet end, so it can be protected by the detachable louvers 11 to prevent water droplets from being sucked into the interior during air intake. After the detachable louvers 11 are removed, the brush plate 613 inside can be cleaned or replaced. At the same time, the air outlet mesh plate 12 protects the air outlet end of the exhaust fan 603 to prevent external dust and impurities from entering the battery compartment housing 2 when the exhaust fan 603 stops rotating and blowing air.

[0040] Brief description of the usage process: By turning on the second motor 601 to rotate in the forward direction, the second motor 601 can drive the exhaust fan 603 to rotate through the first one-way overrunning clutch 602, blowing the gas inside the battery compartment box 2 outward, allowing outside air to enter the battery compartment box 2 through the air inlet chute 608 and after being filtered by the protective net 609, so that the air inside the battery compartment box 2 can circulate, thereby ventilating and dissipating heat inside the battery compartment box 2. Since the exhaust fan 603 and the rotating rod 604 are connected to the output end of the second motor 601 via the first one-way overrunning clutch 602 and the second one-way overrunning clutch 605 respectively, when the second motor 601 is turned on and rotates in the forward direction, it will drive the exhaust fan 603 to rotate. Although the second motor 601 will also drive the synchronous pulley 606 and the synchronous belt 607, it can only drive the second one-way overrunning clutch 605 to idle. Therefore, when the second motor 601 is turned on and rotates in the reverse direction, the second motor 601 will drive the first one-way overrunning clutch 602 to idle, preventing the exhaust fan 603 from rotating. The second motor 601 can then be driven synchronously through the synchronous pulley 606 and the synchronous belt 607, and then rotate through the second one-way overrunning clutch 605. The rod 604 rotates; then the rotating rod 604 drives the rotating cylinder 615 to rotate inside the battery compartment 2 through the synchronous wheel 606. The rotating cylinder 615 drives the reciprocating screw 611 to rotate inside the C-shaped cylinder 610 after the two bevel gears 6141:1 mesh with each other. This causes the reciprocating screw 611 to engage with the second screw sleeve 612, which in turn drives the brush plate 613 to slide up and down on one side of the protective net 609. When the exhaust fan 603 rotates and blows air outward, outside air will enter through the side of the protective net 609 away from the inside of the battery compartment 2. Therefore, dust accumulates on this side, and the brush plate 613 is also located on this side. This allows the dust on the surface of the protective net 609 to be swept away and discharged through the inclined groove at the bottom of the air inlet inclined groove 608. Meanwhile, since the rotating rod 604 is slidably connected inside the rotating cylinder 615 through the polygonal insert rod 616, when the battery compartment folding and expansion mechanism 5 drives the movable side plate 3 away from the battery compartment body 2 to slide and expand, it will also drive the polygonal insert rod 616 to slide inside the rotating cylinder 615. The polygonal insert rod 616 can still directly drive the rotating cylinder 615 to rotate inside the battery compartment body 2, so that the battery compartment body 2 and the movable side plate 3 do not affect the cleaning of the sliding frame 509 after the internal space is expanded.

[0041] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0042] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
