New energy vehicles have the advantages of low cost, stable driving, fuel saving, and reduced exhaust emissions, and are growing explosively. With the emergence of more and more new energy vehicles, it will be a difficult problem for the new energy vehicle industry to achieve fast battery power replenishment. At present, the main methods for battery power replenishment of new energy vehicles include charging pile charging and battery replacement mode. The charging pile charging has low charging efficiency and takes several hours to fully charge the battery. Moreover, the charging pile occupies a large area and the number of charging piles is limited. The battery replacement mode refers to centralized charging of a large number of batteries, centralized charging, unified distribution, and battery replacement service for electric vehicles in the battery distribution station. Therefore, the battery replacement mode can solve the problem of long charging time. There are three battery replacement modes, including chassis battery replacement, front compartment / tail battery replacement, and side wall battery replacement.

[0003] In the chassis battery replacement mode, one way is to lift the vehicle by a lifting machine, and the battery replacement trolley enters the bottom of the vehicle to replace the battery. During the entire battery replacement process of the vehicle, the driver is in the vehicle all the time. Since the vehicle needs to be repeatedly lifted to cooperate with the battery replacement trolley to perform the battery replacement operation during the disassembly and installation of the battery, the user experience is poor. In addition, another way is to set the battery replacement trolley below the ground, and the battery replacement vehicle is parked above the battery replacement trolley for battery replacement. At this time, since the battery replacement trolley needs to be lifted and pass through the battery replacement opening on the ground to contact the bottom of the vehicle for battery replacement operation, the design of the battery replacement opening on the ground easily causes inconvenience for driving the vehicle, has safety hazards, and also easily causes garbage and other sundries to enter the inside, such as garbage or other sundries, which affects the battery replacement function and has low safety.

Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0083] As shown in Figures 1 to 17 The present application provides a battery replacement platform 1, which is provided below with a shuttle channel 2 for the movement of a battery replacement trolley, and which is provided above with a battery replacement port 3 for the lifting movement of the battery replacement trolley to perform a battery replacement operation, the battery replacement port 3 being provided with a protective door 4 and a driving device 5, the driving device 5 driving the protective door 4 to move to open or close the battery replacement port 3.

[0084] It should be noted that the battery replacement platform 1 can be a frame structure built by a support and a patterned steel cover plate, or a closed three-dimensional structure connected by a patterned steel cover plate, and the specific shape and building method are not limited by the present embodiment.

[0085] The battery replacement platform 1 is used for the parking of a vehicle, and when the vehicle is parked on the battery replacement platform 1, the bottom of the battery replacement platform 1 is provided with a shuttle channel 2 allowing the free access of a battery replacement trolley, the battery replacement trolley reaches the position of the battery replacement port 3 in the shuttle channel 2, and the position of the chassis battery of the vehicle is opposite to the battery replacement port 3. The battery replacement platform 1 is provided with a battery replacement port 3 at the middle position thereof for the battery replacement operation of the trolley, the battery replacement port 3 is provided to facilitate the exposure of the chassis of the vehicle for the battery replacement operation of the trolley below the battery replacement port 3. The battery replacement port 3 is connected with a protective door 4, the protective door 4 is movably connected with the battery replacement platform 1 to open the battery replacement port 3 or close the battery replacement port 3 by opening or closing the protective door 4, and when the protective door 4 is opened to open the battery replacement port 3, the battery replacement trolley is below the battery replacement port 3 to perform the battery replacement operation on the battery of the vehicle.

[0086] With the above setup, the battery swapping platform 1 can be located underground. When the top surface of the battery swapping platform 1 is flush with the ground, the vehicle does not need to be lifted by a lifting mechanism or driven onto a ramp to raise the vehicle. The driver can drive the vehicle into the battery swapping platform 1 as if driving on the ground. Furthermore, the driver can get out of the vehicle or remain in the driver's cab throughout the entire battery swapping operation, providing a good user experience. The battery swapping trolley is submerged in the underground space and will not interfere with ground components or vehicles. A shuttle channel 2 is provided below the battery swapping platform 1 for the trolley to move. The trolley can travel underground through the shuttle channel 2 to the battery swapping port 3 of the battery swapping platform 1. When the protective door 4 is open, the battery swapping port 3 is open, allowing the trolley to access the bottom of the vehicle and perform corresponding battery removal, installation, and replacement. When the battery swapping is complete, the trolley leaves the battery swapping port 3 through the shuttle channel 2, and the protective door 4 closes the battery swapping port 3. A movable protective door 4 is installed. When a battery swapping operation is required, the protective door is opened to allow the battery swapping port to be open. When no battery swapping operation is required, the protective door is closed. On the one hand, it can protect the battery swapping port 3, effectively preventing garbage or other debris from falling into the battery swapping port 3 and causing environmental pollution. On the other hand, it can effectively prevent people from accidentally entering the battery swapping port 3 and causing injury, thus increasing safety. Furthermore, it can also prevent drivers from seeing the pit when driving into the battery swapping platform 1 and being afraid to continue driving forward, thus improving the user experience.

[0087] Implementation method one: such as Figures 1 to 3 As shown, the protective door 4 has a folding part 6, which is connected to a connecting device; the driving device 5 drives the folding part 6 to extend or fold through the connecting device.

[0088] In this design, the protective door 4 is equipped with a folding section 6 featuring accordion pleats. When the protective door 4 is opened, the folding section 6 folds from one side to the other, allowing the entire protective door to be stored to one side, or even completely hidden within the wall of the battery swapping platform 1. This reduces the space occupied by the protective door 4, making the space appear more open. Furthermore, the layered folding method is flexible and versatile, enhancing the user experience. When the protective door 4 needs to be closed, the folding section 6 gradually extends from the retracted side, resembling flowing waves, increasing visual appeal and enhancing the user experience.

[0089] Preferably, such as Figure 1 As shown, the connecting device includes a connecting bracket 7 connected to the folding part 6 and a plurality of connecting blocks 8 arranged along the length direction of the folding part 6; the connecting bracket 7 is connected to the driving device 5; the connecting blocks 8 are movably connected to the battery swapping platform 1.

[0090] Specifically, the connecting bracket 7 is connected to the bottom of the moving end of the folding part 6, a circular through hole is formed in the connecting bracket 7, a connecting through hole is formed in the driving end of the driving device 5 corresponding to the circular through hole, and the driving end is fixedly connected with the connecting bracket 7 by a pin shaft or a fixing member penetrating the circular through hole and the connecting through hole. The moving end of the folding part 6 is pushed by the driving end of the driving device 5 to fold towards the fixed end of the folding part 6, so that the moving end and the fixed end of the folding part 6 are located on one side of the battery replacement platform 1, and the entire battery replacement opening 3 is opened. When it is needed to close the battery replacement opening 3, the moving end of the folding part 6 is moved by the driving end of the driving device 5 to return to a side away from the fixed end of the folding part 6, and finally the folding part 6 entirely covers the battery replacement opening 3.

[0091] In the scheme, the driving device 5 is connected with the protective door 4 through the connecting bracket 7, and the driving device 5 drives the protective door 4 to sequentially perform unfolding or folding movement towards one side through the connecting bracket 7. The connecting block 8 is connected to the bottom of the protective door 4 and plays a supporting role for the protective door 4. The connecting block 8 is movably connected to the battery replacement platform 1 and plays a guiding role for the protective door 4, so that the protective door 4 translates along the battery replacement platform 1, and further realizes the unfolding or folding movement of the protective door 4.

[0092] Preferably, the battery replacement platform 1 is provided with a track protruding towards the folding part 6, or the battery replacement platform 1 is provided with a track protruding upwards, and the connecting block 8 is movably connected to the track.

[0093] In embodiment 1, the inner side of the battery replacement platform 1 is provided with a protruding track along the length direction of the battery replacement platform 1, and the track is opposite to the two side edges of the protective door 4. The outer side of the protective door 4 along the length direction is connected with a positioning block, the positioning block is movably connected with the track, and the protective door 4 can translate along the track through the positioning block to realize the opening or closing of the protective door 4 relative to the battery replacement opening 3.

[0094] In embodiment 2, the inner side of the battery replacement platform 1 is provided with a track protruding upwards along the length direction of the battery replacement platform 1, and the track is located at the bottom of the protective door 4. The bottom of the protective door 4 is connected with a positioning block movably connected with the track on one side corresponding to the track, and the protective door 4 can move above the track through the positioning block to realize the opening or closing of the protective door 4 relative to the battery replacement opening 3.

[0095] In this solution, the battery swapping platform 1 is equipped with a track protruding towards the folding part 6, allowing the horizontal side of the folding part 6 of the protective door 4 to be movably connected to the battery swapping platform 1. At this time, the connecting block 8 is connected to the side of the protective door 4. Through the movable connection between the connecting block 8 and the track protruding towards the folding part 6 of the battery swapping platform 1, the protective door 4 receives horizontal support, thus ensuring smooth horizontal sliding of the protective door 4 and preventing uneven force distribution on both sides, which could lead to one side of the protective door 4 being squeezed, causing it to tilt and jam when extending or folding horizontally; or, the The battery swapping platform 1 has an upward-protruding track. A connecting block 8 is connected to the bottom of the protective door 4, allowing the protective door 4 to move and connect to the upward-facing track of the battery swapping platform 1 via the connecting block 8. This ensures that the protective door 4 receives equal support in the vertical plane, preventing it from collapsing in the vertical plane and avoiding resistance when the drive device 5 drives the protective door 4 to make horizontal displacement. Whether supporting the side or bottom of the protective door 4 in the horizontal direction, the protective door 4 is protected, ensuring smoother opening and closing and thus improving battery swapping efficiency.

[0096] Example 3: As Figure 3 As shown, the battery swapping platform 1 has relatively distributed grooves 9, and the connecting block 8 is fitted with a roller 10, which moves along the groove 9.

[0097] Specifically, such as Figure 3 As shown, a groove 9 is provided on the inner side of the battery swapping platform 1 facing the protective door 4. The groove 9 is provided along the length direction of the battery swapping platform 1. Connecting blocks 8 are respectively connected to both sides of the protective door 4 along the length direction. Rollers 10 are rotatably connected to the connecting blocks 8. The rollers 10 can roll in the groove 9 to drive the protective door 4 to move along the groove 9.

[0098] In this design, the battery swapping platform 1 has a groove 9 inside, and a connecting block 8 is connected to a roller 10 for moving within the groove 9. When the protective door 4 extends or folds, the roller 10 rolls within the groove 9 to move the protective door 4 along the groove 9 of the battery swapping platform 1. The recessed design of the groove 9 on the battery swapping platform 1 reduces the space occupied by the battery swapping platform 1, allows for an embedded connection between the protective door 4 and the battery swapping platform 1, reduces the distance between the protective door 4 and the battery swapping platform 1, reduces dust intrusion, facilitates cleaning, and the concealed design makes the appearance more aesthetically pleasing and enhances the user experience.

[0099] Implementation Method Two: (e.g.) Figures 4-5As shown, the protective door 4 includes a first protective door and a second protective door; the first protective door and the second protective door are respectively connected to the connecting device;

[0100] like Figure 5 As shown, the connecting device includes a rotating shaft 11 and multiple support rods 12; the two ends of the rotating shaft 11 along the axial direction are rotatably connected to the battery swapping platform 1, and the driving device 5 is connected to the rotating shaft 11 through a rotating connector 13; the first end of the support rod 12 is connected to the rotating shaft 11, and the second end of the support rod 12 is hinged to the protective door 4. The protective door 4 can rotate relative to the battery swapping platform 1 under the rotation of the rotating shaft 11 to open or close the battery swapping port 3.

[0101] It should be noted that the number of support rods 12 is not limited by this embodiment. In order to maintain the balance of the protective door 4 during rotation, the number of support rods 12 should not be less than two. In this embodiment, two support rods 12 are used.

[0102] Specifically, such as Figure 5 As shown, the rotating connector 13 has a certain curvature. One end of the rotating connector 13 is connected to the driving end of the driving device 5, and the other end of the rotating connector 13 is connected to the rotating shaft 11. The fixing block 14 is fixedly connected to the inner side of the battery swapping platform 1. The two ends of the rotating shaft 11 along the axial direction are rotatably connected to the fixing block 14, so that the rotating shaft 11 is rotatably connected to the battery swapping platform 1 through the fixing block 14. The circumference of the rotating shaft 11 is connected to the driving device 5 through the rotating connector 13. A support rod 12 is connected to the rotating shaft 11 at a position relative to the rotating connector 13. One end of the support rod 12 is fixedly connected to the rotating shaft 11, and the other end is hinged to the bottom of the protective door 4.

[0103] The structure of the support rod 12 is not limited to the specific implementation method, and any of the following embodiments can be adopted:

[0104] Example 1: The support rod 12 adopts a straight structure. One end of the support rod 12 is connected to the rotating shaft 11, and the other end of the support rod 12 is hinged to the bottom of the protective door 4. When the rotating shaft 11 rotates towards the outside of the battery swapping platform 1, the support rod 12 drives the first protective door or the second protective door to move towards the outside of the battery swapping platform 1 respectively. Since one end of the support rod 12 is fixedly connected to the rotating shaft 11, it drives the first protective door or the second protective door to move outward. The other end of the support rod 12 is hinged to the first protective door or the second protective door. When the first protective door or the second protective door moves outward under the drive of the support rod 12, it falls inward and downward under its own gravity. The middle part of the protective door 4 makes an arc movement, and the two sides of the protective door 4 along the length direction make smooth movements, so that the protective door 4 forms an inward swing door structure and remains perpendicular to the battery swapping platform 1.

[0105] Example 2: As Figure 5 As shown, the support rod 12 has a first positioning end 15 and a second positioning end 16; a downwardly protruding curved portion 17 is located between the first positioning end 15 and the second positioning end 16, the curved portion 17 having a certain arc. The first positioning end 15 of the support rod 12 is fixedly connected to the rotating shaft 11, and the second positioning end 16 of the support rod 12 is hinged to the bottom of the protective door 4; when the rotating shaft 11 rotates towards the outside of the battery swapping platform 1, the second positioning end 16 of the support rod 12 drives the first or second protective door to move towards the outside of the battery swapping platform 1. Since the second positioning end 16 needs to avoid the first or second protective door, The door frame of the protective door is designed such that the second positioning end 16 has a downwardly protruding curved part 17. This design allows the second positioning end 16 to move around the door frame and outside the door frame of the battery swapping platform 1, thus moving the first or second protective door outside the battery swapping platform 1. To further enable the first or second protective door to move parallel to the outside of the battery swapping platform 1, preferably, the connecting device also includes a pull rod 18. In a preferred embodiment, the first end of the pull rod 18 is hinged to the protective door 4, and the second end of the pull rod 18 is hinged to the battery swapping platform 1.

[0106] The pull rod 18 and the support rod 12 together form a four-bar linkage mechanism that allows the first or second protective door to have a certain movement trajectory. This causes the first or second protective door to swing outwards, ensuring that after opening, it is horizontally positioned outside the battery swapping platform and parallel to it. It is worth noting that the distance between the first or second protective door and the top surface of the battery swapping platform 1 after its parallel movement must be less than the distance between the bottom of the vehicle and the battery swapping platform 1. This prevents the first or second protective door from failing to fully open and form the swing-out door structure. The lengths of the pull rod 18 and the support rod 12 can be adjusted according to the height range of the first or second protective door.

[0107] In this design, the pull rod 18 is positioned between the protective door 4 and the battery swapping platform 1 to support the protective door 4 above the battery swapping platform 1. This prevents the protective door 4 from tilting during its movement relative to the battery swapping platform 1, thus avoiding malfunctions when opening or closing the protective door 4. Furthermore, the pull rod 18 is hinged to both the protective door 4 and the battery swapping platform 1, allowing the protective door 4 to rotate freely relative to the battery swapping platform 1. Under the connection of the pull rod 18, the protective door 4 can move relative to the battery swapping platform 1 at a preset angle, limiting the opening angle and position of the protective door 4 to prevent excessive rotation angles that could prevent it from closing, thereby increasing the safety and stability of the protective door 4.

[0108] Furthermore, in this scheme, the protective door 4 is configured to include a first protective door and a second protective door, which are respectively connected to the connecting device. This allows the first and second protective doors to be opened or closed to the sides, reducing the waiting time for opening or closing. The drive device 5 is connected to the circumference of the rotating shaft 11, enabling the drive device 5 to drive the rotating shaft 11 to rotate. The support rod 12 is connected to the protective door 4 and the rotating shaft 11 respectively, so that when the rotating shaft 11 rotates, the support rod 12 drives the protective door 4 to rotate relative to the battery swapping platform 1, thereby realizing the rapid opening or closing of the protective door 4. It is only necessary to start the rotating shaft 11 to rotate counterclockwise or clockwise to realize the opening or closing of the protective door 4, thus improving the battery swapping efficiency.

[0109] Preferably, the first protective door and the second protective door are arranged along the width direction of the battery swapping platform 1; or, the first protective door and the second protective door are arranged along the length direction of the battery swapping platform 1.

[0110] In this scheme, the first protective door and the second protective door can be set along the length of the battery swapping platform 1, which can increase the space for the installation of the drive device 5 and the connecting device; the first protective door and the second protective door can also be set along the width of the battery swapping platform 1 to reduce the moving distance of the protective door 4 and increase the battery swapping efficiency.

[0111] Implementation Method 3: For example Figures 6 to 9 As shown, the connection device includes a connection plate 19 connected to the battery swapping platform 1 and a moving component 20 connected to the protective door 4; the moving component 20 is movably connected to the connection plate 19, and the protective door 4 can be translated along the connection plate 19 by the moving component 20 under the driving action of the driving device 5 so that the battery swapping port 3 can be opened or closed.

[0112] Specifically, the connecting plate 19 can be plate-shaped, with both sides of the connecting plate 19 along its length connected to the bottom of the battery swapping port 3 of the battery swapping platform 1, and the connecting plate 19 is vertically positioned below the protective door 4; the driving device 5 is directly connected to the protective door 4, and the protective door 4 is movably connected to the connecting plate 19 through the moving component 20. The driving device 5 drives the protective door 4 to move linearly along the connecting plate 19, thereby enabling the opening or closing of the battery swapping port 3.

[0113] In this scheme, the connecting plate 19 is connected to the battery swapping platform 1 and located below the protective door 4, providing effective support for the protective door 4 and preventing it from collapsing in the horizontal plane and becoming unstable. Furthermore, the connecting plate 19 acts as a guide for the protective door 4, guiding its movement. The connecting plate 19 ensures the movement path of the protective door 4, allowing it to move horizontally along a predetermined path. The protective door 4 can be moved along the connecting plate 19 to open or close, thereby ensuring the safety and convenience of the protective door 4's stable operation and improving battery swapping efficiency.

[0114] Example 1: As Figure 7 As shown, a guide rail 21 is provided in the extending direction of the connecting plate 19; the moving component 20 includes a first connector 201, a second connector 202 and a guide roller 203; one end of the first connector 201 and the second connector 202 are respectively connected to the protective door 4, and the other end of the first connector 201 and the second connector 202 are rotatably connected to the guide roller 203, which is rolled on the guide rail 21.

[0115] Specifically, the first connector 201 and the second connector 202 are rod-shaped structures. The connecting plate 19 is inclinedly connected to the bottom of the protective door 4. The first connector 201 and the second connector 202 are symmetrically arranged and spaced a certain distance apart. The purpose is to connect the guide roller 203 between the first connector 201 and the second connector 202. One end of the bottom of the first connector 201 and the second connector 202 is provided with a through hole. The through hole is connected with a bearing. The two ends of the guide roller 203 in the axial direction are rotatably connected to the through hole through the bearing. During installation, the circumferential surface of the conductive roller is first inserted into the guide rail 21 in the connecting plate 19. When the driving device 5 drives the protective door 4 to move to one side, the guide roller 203 moves along the guide rail 21 in the same direction as the protective door 4, thereby realizing the linear movement of the protective door 4 along the guide rail 21 of the connecting plate 19, realizing the opening and closing of the power exchange port 3.

[0116] In this design, a guide rail 21 is provided inside the connecting plate 19 to guide the movement direction of the protective door 4. The movable component 20 connected to the bottom of the protective door 4 is movably connected to the guide rail 21, so that the protective door 4 is driven by the movable component 20 to reciprocate along the guide rail 21 of the connecting plate 19, thereby realizing the opening and closing of the protective door 4. The guide rail 21 can ensure the movement path of the protective door 4 and prevent the protective door 4 from deviating during the movement, which would prevent the protective door 4 from opening and closing smoothly. Furthermore, the first connecting member 201 and the second connecting member 202 are fixedly connected to the bottom of the protective door 4, and the guide roller 203 is connected between the first connecting member 201 and the second connecting member 202. The guide roller 203 is rolled within the guide rail, further providing stable support for the protective door 4, so that the protective door 4 can run smoothly along the guide rail 21, thereby improving the battery swapping efficiency.

[0117] Preferably, such as Figure 7 As shown, the closed end of the guide rail 21 is provided with an upwardly curved arc transition section 22, so that the protective door 4 rises along the arc transition section 22 of the guide rail 21 to be flush with the top surface of the battery swapping platform 1.

[0118] Specifically, the guide rail 21 has two ends along its extension direction. The end facing the door frame of the power swapping port 3 is the starting end. Here, the guide rail 21 can be open, meaning that the guide rail 21 and the connecting plate 19 are not closed but open, or the starting end of the guide rail 21 can be designed as closed. The end of the guide rail 21 facing the center of the power swapping port 3 is the closed end. When the protective door 4 moves towards the closed end, the power swapping port 3 can be closed. In order to ensure that the top surface height of the protective door 4 is consistent with that of the power swapping platform 1... The top surfaces are at the same height, meaning the top surface of the battery swapping platform 1 and the top surface of the protective door 4 are on the same horizontal plane. When the protective door 4 needs to be moved toward the center of the battery swapping port 3, it also needs to move upward. Therefore, the closed end of the guide rail 21 is designed with an upwardly curved arc transition section 22, so that the guide roller 203 moves upward in an arc trajectory. The protective door 4 moves upward in parallel under the drive of the first connector 201, the second connector 202, and the guide roller 203, so that the top surface of the protective door 4 is flush with the top surface of the battery swapping platform 1.

[0119] In the scheme, in order to enable the first protective door and the second protective door to be closed in the middle when running along the guide rail 21, the guide rail 21 needs to extend to the middle close to the battery replacement platform 1, and one end extending to the middle of the battery replacement platform 1 serves as the closing end of the guide rail 21; in order to enable the first protective door and the second protective door on both sides to be flush with the top surface of the battery replacement platform 1 under the guidance of the closing end, the closing end of the guide rail 21 is provided with an upwardly curved arc transition section 22, when the first protective door and the second protective door on both sides are close to each other to be closed, the guide rollers 203 at the bottom of the first protective door and the second protective door move along the arc transition section 22, and since the arc transition section 22 is upwardly curved, the guide rollers 203 can push the first protective door and the second protective door to move upward, so as to finally realize that the top surfaces of the first protective door and the second protective door are flush with the top surface of the battery replacement platform 1.

[0120] Specifically, as shown in Figure 8 the inner side of the battery replacement platform 1 is provided with a guide rail 23, and the side of the protective door 4 facing the guide rail 23 is rotationally connected with a roller 24 through a positioning piece, and the roller 24 rolls along the guide rail 23.

[0121] In the scheme, the guide rail 23 is arranged on the battery replacement platform 1, and the protective door 4 is provided with the roller 24 in rolling connection with the guide rail 23, so that the protective door 4 can move along the guide rail 23 of the battery replacement platform 1, further increasing the support force on the protective door 4, and in addition, the protective door 4 can move along the predetermined route under the guidance of the guide rail 23, protecting the protective door 4 from being skewed during movement, and avoiding causing the protective door 4 to be unable to be smoothly opened or closed.

[0122] Embodiment 2: as shown in Figures 10 to 13 the connecting device includes a connecting assembly 25 and a guide assembly 26; the bottom of the protective door 4 is connected with a door plate 30 through the connecting assembly 25; the guide assembly 26 is connected to the side of the battery replacement platform 1 facing the protective door 4, and the protective door 4 can be translated under the driving action of the driving device 5 to abut the connecting assembly 25 and the guide assembly 26, and the connecting assembly 25 moves along the guide assembly 26 to drive the protective door 4 to move upward to be flush with the battery replacement platform 1.

[0123] In this scheme, a door panel 30 is provided at the bottom of the protective door 4, and a connecting component 25 is connected between the door panel 30 and the protective door 4. The connecting component 25 effectively supports the protective door 4. At the same time, the door panel 30 and the protective door 4 are hinged together, which can push the protective door 4 to move upward relative to the door panel 30 under the drive of the guide component 26 so that the protective door 4 is flush with the top surface of the battery swapping platform 1. The guide component 26 is connected to the battery swapping platform 1 and serves as a fulcrum for the upward movement of the connecting component 25. The guide component 26 is positioned to engage with the connecting component 25 when it moves to the guide component 26. This allows the connecting component 25 to move along the guide component 26, thereby causing the door panel 30 and the protective door 4 to move upward, so that the protective door 4 and the door panel 30 are flush with the top surface of the battery swapping platform 1. The purpose of the protective door 4 being flush with the top surface of the battery swapping platform 1 is to prevent the protective door 4 from being lower than the height of the battery swapping platform 1, which would cause the driver to see a visual indentation when driving into the battery swapping platform 1 and be afraid to drive into it. At the same time, the protective door 4 being flush with the top surface of the battery swapping platform 1 makes the battery swapping platform 1 flatter and more aesthetically pleasing, improving the user experience.

[0124] Example 1: such as Figure 11 and Figure 12 As shown, the connecting component 25 includes a first link bracket 251 and a second link bracket 252 hinged between the protective door 4 and the door panel 30; when the first link bracket 251 moves to abut against the guide component 26, it can drive the protective door 4 to move upward to be flush with the battery swapping platform 1 under the guidance of the guide component 26.

[0125] Specifically, the protective door 4 includes a first protective door and a second protective door arranged along its length. The first and second protective doors have the same structure, and the first protective door will be used as an example for explanation. The bottom of the first protective door is rotatably connected by a first connecting rod bracket 251 and a second connecting rod bracket 252. The first connecting rod bracket 251 and the second connecting rod bracket 252 are located on both sides of the first protective door, with the first connecting rod bracket 251 closer to the opening and closing side of the first protective door. When the first connecting rod bracket 251, together with the first protective door, moves towards the center of the battery swapping port 3 to close, the first connecting rod bracket 251 can abut against the guide component 26 connected to the battery swapping platform 1, and the first connecting rod bracket 251 can move upward along the guide component 26, so that the first protective door moves upward parallel under the action of the first connecting rod bracket 251, thereby making the top surface of the first protective door flush with the top surface of the battery swapping platform 1. Similarly, the second protective door moves relative to the first protective door, so that the top surface of the second protective door remains flush with the top surface of the battery swapping platform 1.

[0126] The first connecting rod support 251 and the second connecting rod support 252 are connected between the protective door 4 and the door plate 30, so that two-point support can be achieved between the protective door 4 and the door plate 30, and the imbalance of the connection between the protective door 4 and the door plate 30 can be avoided, so that the protective door 4 does not appear to be inclined relative to the door plate 30. The first connecting rod support 251 and the second connecting rod support 252 are both hingedly connected between the protective door 4 and the door plate 30, so that a certain movement space can be achieved between the protective door 4 and the door plate 30, thereby facilitating the upward movement of the protective door 4 relative to the door plate 30, so that the protective door 4 is flush with the top surface of the battery replacement platform 1.

[0127] The connecting device further comprises a connecting seat connected to the lower side of the door plate 30 along the length direction of the door plate 30, and the driving device 5 is arranged in the connecting seat.

[0128] In the present scheme, the connecting seat is arranged below the door plate 30, so that the driving device 5 can be connected to the lower side of the door plate 30 through the connecting seat. The driving device 5 is fixed through the connecting seat, which increases the stability and detachability of the connection between the driving device 5 and the door plate 30. The connection between the driving device 5 and the door plate 30 is more flexible, and the driving device 5 and the connecting seat can be connected through a pin shaft. When the driving device 5 drives the door plate 30 to move, there is a certain amount of rotation between the driving device 5 and the door plate 30. When the door plate 30 appears to be locally deformed and protrudes downward, the driving device 5 has a certain amount of rotation relative to the door plate 30, so that the driving device 5 does not interfere with the door plate 30, thereby reducing the friction between the driving device 5 and the door plate 30.

[0129] As shown in Figure 12 The guide assembly 26 comprises a pulley support 261 and a pulley 262 connected thereto. The pulley support 261 is connected to the side of the battery replacement platform 1 facing the door plate 30, and the first connecting rod support 251 is abuttingly connected to the pulley 262.

[0130] In the present scheme, the pulley support 261 connected with the pulley 262 is connected to the side of the battery replacement platform 1 facing the door plate 30. The purpose is to enable the first connecting rod support 251 of the connecting assembly 25 to abut the pulley 262 on the pulley support 261. Since the first connecting rod support 251 is obliquely connected between the door plate 30 and the protective door 4, the first connecting rod support 251 can move upward along the pulley 262 when moving along the pulley 262, thereby driving the protective door 4 to move upward to be flush with the top surface of the battery replacement platform 1.

[0131] Preferably, as shown in Figure 13As shown, the first connecting rod support 251 has a first connecting section 2511 and a second connecting section 2512 in the length direction; the second connecting section 2512 has a circular arc transition surface 28 towards one side of the battery replacing platform 1, so that the door plate 30 moves upwards along the circular arc transition surface 28 to be flush with the battery replacing platform 1.

[0132] In this scheme, the first connecting rod support 251 has a first connecting section 2511 and a second connecting section 2512, and the purpose is that the second connecting section 2512 of the first connecting rod support 251 first contacts the pulley 262 and slides upwards along the pulley 262, and the second connecting section 2512 has a circular arc transition surface 28 towards one side of the battery replacing platform 1, which can realize the function as the cutting surface of the pulley 262. When the second connecting rod support 252 moves to the position of the pulley 262 and is connected to the pulley 262, the second connecting section 2512 has an upward curved action surface due to the circular arc transition surface 28, which makes the first connecting rod support 251 move upwards to drive the protective door 4 to move upwards, and finally realizes that the protective door 4 is flush with the top surface of the battery replacing platform 1.

[0133] Specifically, as Figure 12 shown, the connecting device further includes a sliding assembly 29, the sliding assembly 29 includes a sliding rail 291 connected to the battery replacing platform 1 and a sliding block 292 movably connected to the sliding rail 291, and the sliding block 292 is connected to the lower side of the door plate 30 to drive the door plate 30 to translate along the sliding rail 291.

[0134] Example 2: as Figures 14 to 17 shown, the connecting assembly 25 includes a first connecting rod assembly 253 and a second connecting rod assembly 254; the first connecting rod assembly 253 is connected between the protective door 4 and the door plate 30; the second connecting rod assembly 254 can abut the protective door 4 to move upwards to be flush with the battery replacing platform 1 when it moves to abut the longitudinal beam 32 of the battery replacing platform 1.

[0135] In the scheme, the first connecting rod assembly 253 is connected between the protective door 4 and the door plate 30, and the first connecting rod assembly 253 supports the protective door 4, and the protective door 4 can move freely relative to the door plate 30 by the action of the first connecting rod assembly 253, so that the protective door 4 and the door plate 30 have a moving space, thereby ensuring that the protective door 4 can move upward relative to the door plate 30 to keep the protective door 4 flush with the top surface of the battery replacement platform 1; the second connecting rod assembly 254 can be linked with the protective door 4 and the door plate 30, and when the door plate 30 and the protective door 4 move to a position where the second connecting rod assembly 254 abuts against the longitudinal beam 32 of the battery replacement platform 1, the second connecting rod assembly 254 can abut against the protective door 4 to lift the protective door 4 upward relative to the door plate 30, thereby keeping the protective door 4 flush with the top surface of the battery replacement platform 1.

[0136] Specifically, the protective door 4 includes a first protective door and a second protective door arranged along the length direction, and the first protective door and the second protective door are identical in structure, and the first protective door is taken as an example for description. As shown in the drawings, Figure 14 The first connecting rod 2531 and the second connecting rod 2532 are respectively connected to the two sides of the door plate 30 in the moving direction, and are hingedly connected between the door plate 30 and the protective door 4 through the first connecting rod 2531 and the second connecting rod 2532, thereby realizing the rotation between the first protective door and the door plate 30.

[0137] The second connecting rod assembly 254 includes a third connecting rod 2541 and a first rotating wheel 2542 in a V-shaped structure, the third connecting rod 2541 has a connecting end, a positioning end and a guiding end, the positioning end and the guiding end have a certain included angle, the guiding end is rotatably connected with the first rotating wheel 2542, the connecting end is hingedly connected with the top of the door plate 30, the positioning end is inclined toward the bottom of the battery replacement platform 1, and the guiding end is inclined toward the bottom of the first protective door; the bottom of the battery replacement platform 1 is provided with a longitudinal beam 32 along the width direction, and the longitudinal beam 32 is located on both sides of the battery replacement port 3, and the longitudinal beam 32 of the battery replacement platform 1 is rotatably connected with a second rotating wheel 27; when the positioning end moves to the middle of the battery replacement port 3 together with the first protective door, the positioning end touches the second rotating wheel 27, the positioning end and the second rotating wheel 27 are in abutting connection, and at this time the positioning end is limited in the moving direction of the first protective door; the first protective door continues to move to the middle of the battery replacement port 3 under the driving of the driving device 5, the third connecting rod 2541 rotates counterclockwise at the connecting end, the first rotating wheel 2542 of the guiding end abuts against the bottom of the first protective door, and the first protective door is lifted upward under the driving of the circular arc trajectory motion of the guiding end, thereby realizing the parallel motion of the first protective door to keep the top surface of the first protective door flush with the top surface of the battery replacement platform 1. Similarly, the second protective door moves relative to the first protective door to keep the top surface of the second protective door flush with the top surface of the battery replacement platform 1.

[0138] In this scheme, as shown in Figure 14 and Figure 15 The first connecting rod assembly 253 includes a first connecting rod 2531 and a second connecting rod 2532 connected between the door plate 30 and the protective door 4, which realizes the stable support of the two sides of the protective door 4, and also realizes the movement of the protective door 4 relative to the door plate 30. The height distance between the protective door 4 and the door plate 30 can be adjusted, thereby ensuring that the protective door 4 moves upward relative to the door plate 30, so that the protective door 4 is flush with the top surface of the battery replacement platform 1; as shown in Figure 15 The second connecting rod assembly 254 includes a third connecting rod 2541 in the shape of V. The protruding end of the third connecting rod 2541 is arranged downward as a connecting end with the door plate 30. The positioning end and the guide end are respectively inclined upward. The positioning end on one side can be positioned to keep the position unchanged, and the guide end on the other side can abut against the bottom of the protective door 4, so that the guide end can realize the upward pushing action on the protective door 4, thereby realizing the upward movement of the protective door 4 to be flush with the top surface of the battery replacement platform 1.

[0139] Specifically, as shown in Figure 17 The guide assembly 26 includes a lead screw 263 and a sliding rail 264 connected to the battery replacement platform 1. A sliding block 265 is movably connected to the lead screw 263 and fixedly connected to the sliding rail 264. The sliding block 265 is connected to the bottom of the door plate 30. The motor drives the lead screw 263 to rotate to move the sliding block 265 along the sliding rail 264, thereby driving the door plate 30 to move along the sliding rail 264.

[0140] In this scheme, the lead screw 263 and the sliding rail 264 are respectively connected with the sliding block 265. The sliding block 265 can move along the lead screw 263 and the sliding rail 264 at the same time. The lead screw 263 is driven by the motor to drive the sliding block 265 to move along the lead screw 263, thereby realizing that the sliding block 265 can move along the sliding rail 264. The sliding block 265 is connected to the bottom of the door plate 30 and can drive the door plate 30 to translate along the sliding rail 264, thereby realizing the horizontal displacement of the door plate 30 and the protective door 4 along the battery replacement platform 1. The straight line movement path of the protective door 4 and the door plate 30 is ensured, and the protective door 4 and the door plate 30 always move in a straight line along the predetermined route during the movement, without deviation.
