[0091] Example 1

[0092] like Figure 1 As shown, this embodiment discloses a battery swap station for replacing the battery pack of an electric vehicle. The battery swap station includes a battery swap room 1, a base plate 2, and a battery swap device. The battery swap room 1 is used to store the battery pack and realize the charging and discharging of the battery pack. The base plate 2 is used as a battery swap platform for the electric vehicle to realize the parking and guidance of the electric vehicle. The battery swap device is used to transfer the battery pack between the battery swap room 1 and the base plate 2.

[0093] like Figure 2 As shown, the base plate 2 is formed by splicing multiple modules. Specifically, the base plate 2 includes a battery swap module 21, a first connection module 22, a second connection module 23, a third connection module 24, and a driving guide module 25. The modular base plate 2 is easy to assemble, and can assemble related modules according to the actual situation of the battery swap station, thereby improving assembly efficiency. Only the modules need to be assembled on site, shortening the station construction cycle, and can even be assembled in advance and transported to the site as a whole, thereby reducing the cost of station construction. Moreover, the modules of the base plate 2 are convenient for mass production, thereby reducing production costs.

[0094] like Figure 1 and Figure 2 As shown, the number of battery exchange rooms 1 in this embodiment is the same as the number of battery exchange modules 21 and both are four, and the battery exchange rooms 1 and the battery exchange modules 21 are arranged one by one. Specifically, the four battery exchange rooms 1 are respectively arranged at the four corners of the battery exchange station, and the battery exchange modules 21 are arranged in pairs along the direction of vehicle travel, and the battery exchange modules 21 are arranged in pairs perpendicular to the direction of vehicle travel, so that the four battery exchange modules 21 and the four battery exchange rooms 1 are arranged at the four corners of the battery exchange station. The battery exchange module 21 forms a battery exchange station station. The battery exchange station 26 is used for electric vehicles to dock for battery exchange operations.

[0095] In other alternative embodiments, the number of battery exchange modules 21 can be other and at least one, and multiple battery exchange modules 21 can be arranged in sequence along one direction (the direction of vehicle travel or perpendicular to the direction of vehicle travel), or can be arranged in both directions. The number of battery exchange rooms 1 and the number of battery exchange modules 21 can be the same or different. One battery exchange module 21 can correspond to multiple battery exchange rooms 1, or one battery exchange room 1 can correspond to multiple battery exchange modules 21.

[0096] like Figure 2 and Figure 3 As shown, the battery exchange module 21 includes a accommodating groove 211, a wheel positioning area 212, a track installation area 213, and a battery exchange equipment positioning area 214.

[0097] like Figure 3 As shown, the accommodating groove 211 is used to accommodate the lifting mechanism 57 to achieve positioning between the base plate 2 and the lifting mechanism 57. The lifting mechanism 57 is used to lift the electric vehicle to facilitate the battery replacement operation of the electric vehicle by the battery replacement equipment.

[0098] Specifically, Figure 3 As shown, the accommodating groove 211 includes a front accommodating groove 2111 and a rear accommodating groove 2112. The front accommodating groove 2111 and the rear accommodating groove 2112 are arranged at intervals along the driving direction of the vehicle. The front accommodating groove 2111 is used to accommodate a front lifting mechanism to lift the front wheels of the electric vehicle, and the rear accommodating groove 2112 is used to accommodate a rear lifting mechanism to lift the rear wheels of the electric vehicle, thereby realizing the synchronous lifting of the front and rear wheels of the electric vehicle and ensuring the stability of the lifting process of the electric vehicle.

[0099] like Figure 3 As shown, the wheel positioning area 212 is used to install a wheel positioning device for positioning the wheels of the electric vehicle, to achieve positioning between the base plate 2 and the wheel positioning device, and the wheel positioning device is used to achieve positioning of the electric vehicle relative to the battery swapping station 26, to improve the accuracy of battery swapping, and to improve the success rate of battery swapping.

[0100] Specifically, Figure 3 As shown, the wheel positioning area 212 is located on the side of the rear accommodating groove 2112 away from the front accommodating groove 2111 in the vehicle driving direction. Therefore, the electric vehicle is first positioned and corrected by the wheel positioning device before entering the battery replacement station 26 to improve the accuracy of the electric vehicle's parking and improve the success rate of battery replacement.

[0101] like Figure 3 As shown, the track installation area 213 is used to install the track 58 for moving the battery swapping equipment to achieve positioning between the base plate 2 and the track 58. The track 58 is used to achieve and guide the movement of the battery swapping equipment so that the battery swapping equipment can move between the electric vehicle and the battery transfer device 17.

[0102] Specifically, Figure 3 As shown, the rail installation area 213 is located between the front accommodating groove 2111 and the rear accommodating groove 2112 along the vehicle's driving direction, so that the battery swapping equipment can be moved between the front and rear wheels of the electric vehicle, that is, the battery swapping equipment can be moved directly under the electric vehicle to realize the battery swapping operation.

[0103] The track installation area 213 in this embodiment is provided with a first track 2131 and a second track 2132. The first track 2131 and the second track 2132 both extend perpendicular to the direction of travel of the vehicle, and the first track 2131 and the second track 2132 are arranged at intervals in the direction of travel of the vehicle. The battery swapping device is guided by the first track 2131 and the second track 2132 to move in a more accurate manner, thereby improving the success rate of battery swapping.

[0104] In other alternative embodiments, only one track may be provided in the track installation area 213 to guide the moving direction of the battery swapping device.

[0105] like Figure 3 As shown, the battery swapping equipment positioning area 214 is used to realize the positioning of the battery swapping module 21 and the battery swapping equipment, realize the positioning between the bottom plate 2 and the battery swapping equipment, and improve the battery swapping accuracy of the battery swapping equipment.

[0106] Specifically, Figure 3 As shown, the battery swap equipment positioning area 214 is located between the first track 2131 and the second track 2132 along the vehicle travel direction. In this embodiment, the battery swap equipment positioning area 214 is set on the travel path of the battery swap equipment, which facilitates timely identification of the position of the battery swap equipment, improves the movement accuracy of the battery swap equipment, and improves the success rate of battery swapping.

[0107] The battery swap device positioning area 214 includes a magnetic strip installation area 215, which is used to install and position the magnetic strip for the battery swap device. The positioning between the bottom plate 2 and the battery swap device is achieved by positioning the magnetic strip, thereby improving the battery swap accuracy of the battery swap device. Specifically, the battery swap device may be equipped with an induction component that can identify the positioning term, and the mobile position of the battery swap device is determined by the induction between the induction component and the positioning magnetic strip.

[0108] like Figure 2 As shown, the first connection module 22 is arranged between two adjacent battery exchange modules 21 perpendicular to the direction of vehicle travel, and the first connection module 22 is respectively connected to the battery exchange modules 21 on the corresponding side at both ends perpendicular to the direction of vehicle travel. The first connection module 22 is used to form a mobile channel 52 for electric vehicles to move. The mobile channel 52 facilitates electric vehicles to enter or exit the battery exchange station and to move electric vehicles to battery exchange stations 26 at other locations, so as to avoid the rear vehicles being blocked by other electric vehicles in front that are being charged and exchanged, thereby improving the battery exchange efficiency and user experience. In addition, the first connection module 22 is used to form a gap between two adjacent battery exchange stations 26 perpendicular to the direction of vehicle travel to prevent collisions between electric vehicles.

[0109] In other alternative embodiments, if there are no two battery exchange modules 21 adjacent to each other in a direction perpendicular to the vehicle's driving direction, the first connecting module 22 may not be provided.

[0110] like Figure 2 As shown, the second connection module 23 is provided between two battery exchange modules 21 adjacent to each other in the direction of vehicle travel, and the two ends of the second connection module 23 in the direction of vehicle travel are respectively connected to the battery exchange modules 21 on the corresponding side. The second connection module 23 is used to form a gap between two battery exchange stations 26 adjacent to each other in the direction of vehicle travel to prevent electric vehicles from colliding with each other. In other alternative embodiments, if there are no two battery exchange modules 21 adjacent to each other in the direction of vehicle travel, the second connection module 23 may not be provided.

[0111] like Figure 2 As shown, the first connection module 22 is arranged between two adjacent second connection modules 23 perpendicular to the vehicle's driving direction, and the first connection module 22 is connected to the second connection modules 23 on the corresponding side at both ends perpendicular to the vehicle's driving direction, so that the moving channel 52 is connected at both ends in the vehicle's driving direction, which facilitates the movement of the electric vehicle.

[0112] like Figure 2 As shown, the third connection module 24 is disposed on a side of the second connection module 23 away from the first connection module 22 and is connected to the second connection module 23. Figure 1 As shown, the battery swap station in this embodiment further includes a maintenance room 3, which is located between the two battery swap rooms 1 in the direction of vehicle travel. The width of the maintenance room 3 in this embodiment perpendicular to the direction of vehicle travel is smaller than the width of the battery swap room 1 in the direction of vehicle travel, and the third connection module 24 can fill the part of the maintenance room 3 that is smaller than the battery swap room 1 to ensure flatness.

[0113] In other alternative embodiments, if the widths of the maintenance room 3 and the battery exchange room 1 are the same in a direction perpendicular to the direction of travel of the vehicle, the third connection module 24 may not be provided.

[0114] like Figure 5 As shown, the driving guide module 25 is arranged on at least one side of the battery exchange module 21 in the vehicle's driving direction and is connected to the battery exchange module 21 and / or the first connection module 22. The upper end face of the driving guide module 25 is inclined downward from the end close to the battery exchange module 21 to the end away from the battery exchange module 21. The driving guide module 25 is used to guide the electric vehicle to enter or exit the battery exchange station.

[0115] Specifically, the bottom plate 2 is provided with driving guide modules 25 at both ends in the vehicle driving direction, one of which is used to guide the electric vehicle into the battery swap station, and the other is used to guide the electric vehicle out of the battery swap station. The driving guide module 25 is connected to the adjacent battery swap module 21 and the first connection module 22 to ensure the overall connection strength.

[0116] In other alternative embodiments, when the connection strength meets the requirements, the driving guidance module 25 can be connected only to the battery replacement module 21 or only to the first connection module 22.

[0117] Each module of the bottom plate 2 in this embodiment is made of concrete, and the bottom plate 2 made of concrete is low in cost. After each module is formed and transported to the site, the modules are spliced ​​together through a hoisting process. Among them, how to fix the concrete modules belongs to the existing technology in this field and will not be described in detail here.

[0118] In other alternative embodiments, the bottom plate 2 may also be an integrated structure, and the bottom plate 2 may be integrally formed by pouring cement. The first track 2131 and the second track 2132 may also be pre-buried track structures.

[0119] In other alternative embodiments, the base plate 2 may also be made of other materials, such as steel. The base plate 2 made of steel has high strength.

[0120] Example 2

[0121] like Figure 4 As shown, the base plate 2 in this embodiment is basically the same as that in the embodiment 1, except that the connection modes between the modules of the base plate 2 are different.

[0122] Specifically, Figure 4-Figure 6 As shown, each module of the base plate 2 in this embodiment is made of steel. Two adjacent modules in the vehicle driving direction and / or perpendicular to the vehicle driving direction are rotatably connected, so that after each module is assembled, the space occupied by the base plate 2 can be reduced by rotating the corresponding module, which is convenient for transportation to the site, shortens the site construction cycle, and meets the needs of rapid batch site construction in a short time.

[0123] Specifically, Figure 4 As shown, in this embodiment, the battery exchange module 21 and the first connecting module 22 are rotationally connected, the first connecting module 22 and the second connecting module 23 are rotationally connected, the third connecting module 24 and the second connecting module 23 are rotationally connected, and the driving guide modules 25 and the driving guide modules 25 are rotationally connected to facilitate the folding of the base plate 2.

[0124] In other alternative embodiments, between the battery exchange module 21 and the first connection module 22, and / or between the battery exchange module 21 and the second connection module 23, and / or between the first connection module 22 and the second connection module 23, and / or between the third connection module 24 and the second connection module 23, and / or between the battery exchange module 21 and the driving guide module 25, and / or between the first connection module 22 and the driving guide module 25; either a fixed connection by a fastener such as a bolt, or a rotational connection by a rotating member such as a hinge. When the modules are assembled and then transported to the site, the rotational connection method allows the rotationally connected modules to rotate a certain angle to reduce the overall area occupied by the base plate 2 and facilitate transportation.

[0125] Furthermore, if Figure 4-Figure 6 As shown, in this embodiment, two adjacent modules in the vehicle driving direction and / or perpendicular to the vehicle driving direction are rotatably connected by a hinge 5, and the hinge 5 is installed on one end surface of the module in the vehicle height direction. The hinge 5 has a simple structure, high connection reliability, and is convenient for rotating and resetting the module. In addition, the hinge 5 has a small structure and will not interfere with the driving of the electric vehicle.

[0126] Specifically, Figure 6 As shown, the hinge 5 includes a first connecting part 51, a second connecting part 52 and a rotating shaft 53. The first connecting part 51 and the second connecting part 52 are respectively connected to two adjacent modules. The rotating shaft 53 is connected between the first connecting part 51 and the second connecting part 52, and the rotation between the two modules is realized through the rotating shaft 53.

[0127] Furthermore, if Figure 4 and Figure 5 As shown, when hinges 5 need to be installed on both sides of the same module in the same direction, the hinges 5 on both sides of the same module are respectively installed on both sides of the module in the vehicle height direction, so that the two modules adjacent to the module can be rotated in different directions respectively, that is, one module can be rotated from top to bottom, and the other module can be rotated from bottom to top, thereby increasing the rotation range of both and further reducing the space occupied by the base plate 2.

[0128] Furthermore, if Figure 4 and Figure 6 As shown, if two modules adjacent to each other in the vehicle travel direction and / or perpendicular to the vehicle travel direction are not rotationally connected by hinges 5, they are fixedly connected by fixing plates 6. Specifically, the battery exchange module 21 is connected to the driving guide module 25 by fixing plates 6, the battery exchange module 21 is connected to the second connection module 23 by fixing plates 6, the first connection module 22 is connected to the driving guide module 25 by fixing plates 6, and the first connection modules 22 are connected to the first connection modules 22 by fixing plates 6.

[0129] The fixing plate 6 in this embodiment is a rectangular plate-shaped connecting member with a simple structure and easy processing.

[0130] In other alternative embodiments, it is possible to adjust whether the two adjacent modules are connected in a rotating or fixed manner according to actual needs. It should be noted that the fixing plate 6 and the hinge 5 can be installed on different modules to achieve a connection between two completely different modules. However, if the fixing plate 6 and the hinge 5 are installed in the same module, in order to ensure that the fixing plate 6 does not interfere with the rotation of the side of the module where the hinge 5 is installed, the fixing plate 6 and the hinge 5 are installed on different sides of the same module.

[0131] Example 3

[0132] like Figure 4 As shown, the base plate 2 in this embodiment is basically the same as that in the embodiment 1, except that the connection modes between the modules of the base plate 2 are different.

[0133] Specifically, Figure 7-Figure 9 As shown, each module of the bottom plate 2 in this embodiment is made of steel. Two adjacent modules in the vehicle driving direction and / or perpendicular to the vehicle driving direction are fixedly connected. The fixed connection method has high connection strength and is not easy to shift between the modules.

[0134] like Figure 7 and Figure 8 As shown, each module includes a support plate 71 and a plurality of support ribs 72 provided on the lower end surface of the support plate 71. The upper end surface of the support plate 71 is used to support the electric vehicle. The support ribs 72 are used to enhance the strength of the module while reducing the weight of the module.

[0135] like Figure 8 and Fig. 9 As shown, the supporting ribs of two adjacent modules in the vehicle travel direction and / or perpendicular to the vehicle travel direction are detachably connected by fasteners, which facilitates the connection between the two adjacent modules. The detachable connection method facilitates the maintenance of a single module. When a single module is damaged, only the damaged module needs to be repaired or replaced, reducing maintenance costs.

[0136] Specifically, for two modules adjacent to each other in the vehicle driving direction and / or perpendicular to the vehicle driving direction, the support ribs of the two modules are closely arranged. The fasteners include a connecting rod 81 and a connecting nut 82. The connecting rod 81 is passed through the support ribs of the two adjacent modules closely arranged. Both axial ends of the connecting rod 81 are provided with external threads. The axial ends of the connecting rod 81 are retracted on the support ribs through corresponding connecting nuts 82.

[0137] In other alternative embodiments, the fastener may also be a simple bolt structure, and threaded holes are provided on the support ribs to achieve tightening with the bolts. Alternatively, the fastener may also be other connecting pieces that can achieve the above functions.
