As the market share and usage frequency of electric vehicles continue to rise, battery swap stations, which provide battery replacement facilities for electric vehicles, are becoming increasingly popular. Battery swap platforms are a key component of electric vehicle battery replacement equipment.

[0078] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0079] An embodiment of the present utility model discloses a battery swap station, which includes a vehicle carrying platform, battery swap equipment and a foundation. The vehicle carrying platform is installed on the foundation. An electric vehicle that needs to replace the battery pack drives onto the vehicle carrying platform. The vehicle carrying platform is used to position and fix the electric vehicle. The battery swap equipment moves to the bottom of the vehicle carrying platform and performs battery swap operations on the electric vehicle on the vehicle carrying platform. The electric vehicle will drive out of the vehicle carrying platform after the battery pack is replaced.

[0080] The foundation includes a vehicle platform installation area, which is recessed downward to accommodate the vehicle platform. The recessed area accommodates the vehicle platform, providing installation space and facilitating its installation and securement. Furthermore, the surface of the vehicle platform does not extend beyond the foundation. The vehicle platform is installed within the installation area, ensuring that electric vehicles do not experience significant height differences when entering or exiting the platform. This ensures that the platform does not obstruct the electric vehicle, facilitating its passage and effectively preventing bumps.

[0081] like Figures 1 to 7 As shown, the vehicle-carrying platform is used to carry and position electric vehicles for battery replacement. The vehicle-carrying platform includes a movable door 1, a battery replacement port 2, a fixed guide rail 3 and a travel drive device 4. The movable door 1 is installed at the battery replacement port 2 and is used to close or open the battery replacement port 2. A bracket extending along the walking direction is provided under the vehicle-carrying platform. The fixed guide rail 3 is fixed on the bracket in a direction perpendicular to it. The travel drive device 4 is connected to the fixed guide rail 3 and can move on the fixed guide rail 3. The movable door 1 is connected to the travel drive device 4. The travel drive device 4 can drive the movable door 1 to move in the same direction relative to it when moving, thereby closing or opening the battery replacement port 2.

[0082] When the battery swap station is in use, the movable door 1 closes the battery swap port 2, and the electric vehicle drives onto the vehicle loading platform along the driving direction X. The movable door 1 then opens the battery swap port 2, and the battery swap equipment below the vehicle loading platform performs a battery swap operation on the electric vehicle on the vehicle loading platform through the battery swap port 2. After the battery swap is completed, the movable door 1 closes the battery swap port 2, and the electric vehicle drives out of the vehicle loading platform along the driving direction X. By providing the battery swap port 2, the space below the vehicle loading platform is effectively utilized, providing space for the battery swap equipment of the battery swap station, allowing the battery swap equipment to perform a battery swap operation on the electric vehicle on the vehicle loading platform through the battery swap port 2, making it convenient to replace the battery of the electric vehicle without having to lift the electric vehicle. The battery swap process is convenient and simple, and the risks associated with lifting the electric vehicle can also be avoided.

[0083] A movable door 1 is also installed at the battery replacement port 2, and the movable door 1 is driven to move in the same direction relative to the fixed guide rail 3 by the travel drive device 4, so that the battery replacement port 2 is opened by the movable door 1 during the battery replacement period to achieve battery replacement; and the battery replacement port 2 is closed by the movable door 1 during the non-battery replacement period, which is convenient for the electric vehicle to pass through before or after the battery replacement, and also prevents pedestrians or debris from falling into the battery replacement port 2, greatly improving the safety of the vehicle loading platform. The travel drive device 4 moves on the fixed guide rail 3 along the moving direction of the movable door 1, and drives the movable door 1 to move in the same direction relative to the fixed guide rail 3, so that the movable door 1 can travel farther and move more efficiently; and the fixed guide rail 3 and the travel drive device 4 do not need to be set on the entire moving track of the movable door 1, but only need to be set on a part, so that the overall structure is more compact and occupies less space; and the moving speed of the movable door is faster, which improves the battery replacement efficiency.

[0084] like Figure 1 As shown, in this embodiment, the movable door 1 is configured to move in a direction perpendicular to the driving direction of the vehicle to open or close the battery replacement port 2. The movable door 1 is opened perpendicular to the driving direction, which occupies less space for the electric vehicle in the driving direction, making the battery swap station more compact and having high space utilization. Electric vehicles need to frequently enter and exit the vehicle loading platform. By moving the movable door 1 in a direction perpendicular to the driving direction X, the movable door 1 will occupy the space perpendicular to the driving direction X on the vehicle loading platform during the movement, thereby achieving a very small space occupied on the vehicle loading platform in the driving direction X and high space utilization. At the same time, electric vehicles will not affect the normal use of the movable door 1, thereby ensuring the stability of the movable door 1 and extending its service life.

[0085] In this embodiment, the fixed guide rail 3 and the travel drive device 4 are both arranged below the movable door 1. This ensures that the fixed guide rail 3 and the travel drive device 4 do not occupy the space on the top surface of the vehicle loading platform, resulting in high space utilization and no interference with the passage of electric vehicles on the surface of the vehicle loading platform.

[0086] like Figures 3 to 7 As shown, the travel drive device 4 includes a drive mechanism 41 and a travel component 42. The drive mechanism 41 is connected to the travel component 42 and is used to drive the travel component 42 to move on the fixed guide rail 3. The movable door 1 is connected to the travel component 42 and can move on the travel component 42; wherein, the moving direction of the movable door 1 is the same as the moving direction of the travel component 42.

[0087] The driving mechanism 41 is used to provide driving force and drive the walking component 42 to move, so that the walking component 42 moves on the fixed guide rail 3, and the walking component 42 will drive the moving door 1 to move during the movement, so that the moving door 1 can open or close the battery replacement port 2. The moving direction of the moving door 1 is the same as the moving direction of the walking component 42, so that the moving door 1 can travel farther, and the overall structure of the walking drive device 4 is more compact and occupies less space; and the moving speed of the moving door 1 is faster, which improves the battery replacement efficiency. At the same time, the structure of the walking drive device 4 is simple and easy to implement, and it can effectively control the moving door 1, so that the moving door 1 and the battery replacement port 2 can be reliably matched to facilitate battery replacement or passage of electric vehicles.

[0088] The drive mechanism 41 is a pneumatic cylinder, a hydraulic cylinder, or an electric push rod. This allows for the selection of an appropriate drive mechanism 41 based on space, cost, and other factors. It features a simple structure, reliable operation, and ease of installation and maintenance. In this embodiment, the drive mechanism 41 is powered by a hydraulic cylinder, making it easy to control, capable of stepless speed regulation, and equipped with overload protection. Compared to mechanical transmissions, the arrangement of the drive mechanism 41 is more flexible.

[0089] The travel component 42 includes a mounting frame 421, a first travel wheel 422, a second travel wheel 423, and a transmission member 424. The drive mechanism 41 is connected to the mounting frame 421. The first travel wheel 422 and the second travel wheel 423 are both rotatably mounted on the mounting frame 421. The first travel wheel 422 is connected to the fixed guide rail 3 and can move on the fixed guide rail 3. The transmission member 424 is connected to the first travel wheel 422 and the second travel wheel 423. The second travel wheel 423 is connected to the movable door 1 and can move the movable door 1. The drive mechanism 41 is connected to the mounting frame 421 and is used to drive the mounting frame 421 to move, thereby driving the rotation of the first travel wheel 422 and moving it on the fixed guide rail 3. The transmission member 424 is connected to the first travel wheel 422 and the second travel wheel 423. The rotation of the second travel wheel 423 drives the movable door 1 to move, thereby enabling the movable door 1 to open or close the battery replacement port 2. The first running wheel 422, the second running wheel 423, and the transmission member 424 are all mounted on the mounting frame 421, making installation and installation convenient, the structure simple, and the overall structural stability and reliability high. Through the transmission action of the first running wheel 422, the transmission member 424, and the second running wheel 423, the running member 42 moves on the fixed guide rail 3 while simultaneously driving the movable door 1 to move in the same direction relative to it, achieving a longer travel range for the movable door 1, and making the overall structure of the travel drive device 4 more compact and taking up less space; and achieving a faster movement speed for the movable door 1, thereby improving the efficiency of battery replacement.

[0090] like Figure 6 As shown, the outer circumferences of the first and second travel wheels 422, 423 are each provided with a plurality of outwardly protruding first anti-slip teeth 4221. During movement, the first and second travel wheels 422, 423 respectively abut against the fixed guide rail 3 and the movable door 1 via the plurality of outwardly protruding first anti-slip teeth 4221, thereby greatly increasing friction during movement, further ensuring more precise positioning of the travel component 42 and the movable door 1, and moving at a faster speed, thereby improving battery replacement efficiency and enhancing safety.

[0091] In one embodiment, the movable door 1 and the fixed guide rail 3 each have a plurality of inwardly recessed anti-slip grooves along their travel direction, and the first anti-slip teeth 4221 are correspondingly inserted into the anti-slip grooves. When the battery swap station is in use, the drive mechanism 41 drives the moving component 42 to move on the fixed guide rail 3 and the movable door 1. The first and second wheels 422, 423 on the moving component 42 are correspondingly inserted into the anti-slip grooves of the fixed guide rail 3 and the movable door 1 via the first anti-slip teeth 4221. The first anti-slip teeth 4221 abut against the anti-slip grooves, significantly increasing the friction between the first wheel 422 and the fixed guide rail 3, and the second wheel 423 and the movable door 1. This further ensures more precise positioning of the moving component 42 and the movable door 1, faster movement speed, improved battery swap efficiency, and greater safety. Furthermore, the first anti-slip teeth 4221, when inserted into the anti-slip grooves, guide the moving component 42 and the movable door 1 into position, allowing for correction and fine-tuning of the moving component 42 and the movable door 1 during movement, achieving higher accuracy in the positioning of the movable door 1.

[0092] In another embodiment, the movable door 1 and the fixed guide rail 3 are both provided with a plurality of second anti-slip teeth, and the first anti-slip teeth 4221 are engaged with the corresponding second anti-slip teeth. When the battery swap station is in use, the first running wheel 422 is engaged with the second anti-slip teeth on the fixed guide rail 3 through the first anti-slip teeth 4221, and the second running wheel 423 is engaged with the second anti-slip teeth on the movable door 1 through the first anti-slip teeth 4221. This causes the first anti-slip teeth 4221 and the second anti-slip teeth to abut against each other, greatly increasing the friction between the first running wheel 422 and the fixed guide rail 3, and the second running wheel 423 and the movable door 1. This further ensures that the movement and positioning of the moving component 42 and the movable door 1 are more accurate, and the movement speed is faster, thereby improving the battery swap efficiency and safety. At the same time, when the first anti-slip teeth 4221 are engaged with the second anti-slip teeth, they can guide the insertion and alignment, allowing the running component 42 and the movable door 1 to be corrected and fine-tuned during movement, achieving higher accuracy in the movement and positioning of the movable door 1.

[0093] Specifically, in this embodiment, the top surface of the fixed guide rail 3 is provided with a plurality of upwardly protruding second anti-slip teeth, and the plurality of upwardly protruding second anti-slip teeth are spaced apart along the moving direction of the sliding door 1. The bottom surface of the sliding door 1 is provided with a plurality of downwardly protruding second anti-slip teeth, and the plurality of downwardly protruding second anti-slip teeth are spaced apart along the moving direction of the sliding door 1.

[0094] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the transmission member 424 includes a transmission belt 4242 and two transmission wheels 4241. The two transmission wheels 4241 are respectively connected to the first travel wheel 422 and the second travel wheel 423. The transmission belt 4242 is mounted on the two transmission wheels 4241. When the first travel wheel 422 moves on the fixed guide rail 3, it drives the transmission wheel 4241 connected to the first travel wheel 422 to rotate together. The transmission belt 4242 is mounted on the two transmission wheels 4241, causing the two transmission wheels 4241 to rotate together, thereby driving the second travel wheel 423 connected to the transmission wheel 4241 to rotate together, ultimately achieving movement of the movable door 1. The transmission belt 4242 and the two transmission wheels 4241 realize the transmission between the first travel wheel 422 and the second travel wheel 423, achieving high movement stability. At the same time, the overall structure is more compact, occupies less space, and has a simple structure.

[0095] The transmission ratio between the transmission wheel connected to the first travel wheel 422 and the transmission wheel connected to the second travel wheel 423 is greater than 1. Because the transmission ratio between the transmission wheel connected to the first travel wheel 422 and the transmission wheel connected to the second travel wheel 423 is greater than 1, when the first travel wheel 422 moves a certain distance on the fixed guide rail 3, the second travel wheel 423 will drive the movable door 1 to move a greater distance, thereby achieving a longer travel of the movable door 1 and making the overall structure of the travel drive device 4 more compact and occupying less space. At the same time, the movable door 1 can move faster, thereby improving the efficiency of battery replacement.

[0096] Specifically, there are two first running wheels 422. The two first running wheels 422 are respectively arranged at both ends of the mounting frame 421 along the moving direction of the movable door and move on the fixed guide rail 3, so that the moving component 42 is more stable and reliable during the moving process. There is one second running wheel 423. The second running wheel 423 is arranged at the end of the mounting frame 421 close to the battery replacement port 2. One end of the transmission belt 4242 is sleeved on the transmission wheel 4241 coaxially connected to the second running wheel 423, and the other end is sleeved on the transmission wheel 4241 coaxially connected to the first running wheel 422. Among them, the first running wheel 422 coaxially connected to the transmission wheel 4241 is the one farther from the second running wheel 423 of the two first running wheels 422, thereby making the transmission between the first running wheel 422 and the second running wheel 423 more stable and reliable. In this embodiment, the transmission wheel 4241 is a sprocket, wherein the sprocket connected to the first travel wheel has more teeth than the sprocket connected to the second travel wheel, and the transmission belt 4242 is a chain. This achieves more precise, stable, and reliable movement, providing greater safety. Furthermore, it allows for fine-tuning during movement, achieving greater accuracy in the positioning of the movable door 1. Of course, in other embodiments, the transmission wheel 4241 and the transmission belt 4242 may also utilize other transmission components, such as rack and pinion gears, based on actual needs.

[0097] like Figure 4 、 Figure 5 and Figure 7 As shown, the fixed guide rail 3 is provided with at least one first slide groove 32, and the mounting bracket 421 is connected to the first slide groove 32 and can move within the first slide groove 32. The first slide groove 32 serves as a guide, and the traveling component 42 moves within the first slide groove 32 via the mounting bracket 421, so that the traveling component 42 moves in a predetermined direction on the fixed guide rail 3, effectively preventing the traveling component 42 from being offset or misaligned during movement, thereby greatly improving the safety and stability of the vehicle loading platform.

[0098] The top surface of the fixed guide rail 3 has a first rack 31 that cooperates with the first running wheel 422. There are two first slide grooves 32, and the two first slide grooves 32 are respectively located on both sides of the fixed guide rail 3. The mounting frame 421 is connected to the two first slide grooves 32. The first running wheel 422 moves on the top surface of the fixed guide rail 3 and engages with the first rack 31, thereby greatly increasing the friction between the first running wheel 422 and the fixed guide rail, further ensuring that the movement and positioning of the running component 42 and the movable door 1 are more accurate, and the movement speed is faster, improving the power exchange efficiency, and increasing safety. When the first running wheel 422 is engaged with the first rack 31, it can guide the insertion and alignment, so that the running component 42 and the movable door 1 can be corrected and fine-tuned during the movement process, achieving higher accuracy in the movement and positioning of the movable door 1. At the same time, the mounting frame 421 is connected to both sides of the fixed guide rail 3 and moves on the two first slide grooves 32 on both sides, so that the connection stability between the mounting frame 421 and the fixed guide rail 3 is higher, further avoiding the displacement and dislocation of the walking component 42 during the movement, and greatly improving the safety and stability of the vehicle loading platform.

[0099] The mounting frame 421 has a pulley 4211, which is located in the first chute 32. The mounting frame 421 moves in the first chute 32 via the pulley 4211, which greatly reduces friction when the mounting frame 421 moves in the first chute 32, ensuring that the movement of the walking component 42 is more stable and reliable.

[0100] The bottom surface of the sliding door 1 is provided with at least one second chute 12, and the mounting bracket 421 is connected to the second chute 12 and can move within the second chute 12. The second chute 12 acts as a guide, and the running member 42 moves within the second chute 12 via the mounting bracket 421, so that the running member 42 drives the sliding door 1 in a predetermined direction, effectively preventing the sliding door 1 from shifting or misaligning during movement, and greatly improving the safety and stability of the vehicle loading platform.

[0101] The bottom of the movable door 1 has a downwardly protruding movable block 11. The bottom surface of the movable block 11 has a second rack 111 that cooperates with the second running wheel 423. There are two second slide grooves 12, and the two second slide grooves 12 are respectively located on both sides of the movable block 11. The mounting frame 421 is connected to the two second slide grooves 12. The movable door 1 moves on the second running wheel 423 through the movable block 11. The second rack 111 engages with the second running wheel 423, thereby greatly increasing the friction between the second running wheel 423 and the movable door 1, further ensuring that the moving positioning of the movable door 1 is more accurate, and the moving speed is faster, improving the power exchange efficiency, and increasing safety. When the second running wheel 423 is engaged with the second rack 111, it can guide the insertion and alignment, so that the movable door 1 can be corrected and fine-tuned during the movement process, and the moving positioning accuracy of the movable door 1 is higher. At the same time, the mounting bracket 421 is connected to both sides of the moving block 11 and moves on the two second slide grooves 12 on both sides, so that the connection stability between the mounting bracket 421 and the moving door 1 is higher, further avoiding the displacement and dislocation of the moving door 1 during the movement, and greatly improving the safety and stability of the vehicle loading platform.

[0102] like Figure 1 As shown, the vehicle-carrying platform also includes four wheel positioning devices, which are all installed on the platform body and located at the edge of the battery replacement port 2. The four wheel positioning devices are used to position and fix the four wheels of the electric vehicle, effectively avoiding the displacement and dislocation of the electric vehicle during the battery replacement operation, and are safer and more stable.

[0103] The movable door 1 includes a relatively separable first movable portion 13 and a second movable portion 14. The first movable portion 13 and the second movable portion 14 are each driven to move by a travel drive 4. The travel drive 4 drives the corresponding first movable portion 13 and second movable portion 14 to move horizontally in opposite directions to open or close the battery replacement port 2. By moving the first movable portion 13 and the second movable portion 14 closer together to close the battery replacement port 2 and farther apart to open the battery replacement port 2, the size of the single-piece movable door 1 is effectively reduced, correspondingly reducing the opening and closing stroke of the single-piece movable door 1, reducing the support and drive requirements for the movable door 1, and achieving greater stability. Accordingly, there are two fixed guide rails 3 and two travel drive devices 4, each connected below the first movable portion 13 and the second movable portion 14.
