[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figures 1 to 4 The battery swap station of the present invention is described.

[0034] like Figures 1 to 4 As shown, the battery swap station provided by the embodiment of the utility model includes an equipment area 1 and a vehicle parking area.

[0035] In a specific embodiment, the equipment area 1 is provided with a battery replacement device 2 and a charging compartment 3. The charging compartment 3 is used to store and charge the battery 4, and the battery replacement device 2 is used for battery replacement operations.

[0036] The vehicle parking area includes at least two battery exchange channels, each battery exchange channel corresponds to an edge of the equipment area 1.

[0037] Among the edges of the equipment area 1 , the edges corresponding to the battery replacement channels are arranged adjacent to each other in sequence, and the charging compartments 3 are distributed along the remaining edges of the equipment area 1 .

[0038] The battery exchange device 2 is arranged between the charging compartment 3 and the vehicle parking area, and the battery exchange device 2 is used to grab and release the battery 4 and transfer the battery 4 between the charging compartment 3 and the battery exchange channel.

[0039] In this way, the battery exchange channel is arranged corresponding to the edge adjacent to the equipment area 1. When two battery exchange channels need to be set up, the two battery exchange channels correspond to two adjacent edges of the equipment area 1. Compared with the two battery exchange channels corresponding to two parallel edges or two opposite edges of the equipment area 1 (that is, the two battery exchange channels are located on opposite sides of the charging compartment), the overall size of the battery exchange station in the direction perpendicular to the extension direction of the battery exchange channel is effectively reduced, and the structure is more compact. It can be suitable for installation in installation areas with smaller dimensions along the direction perpendicular to the extension direction of the battery exchange channel, and meet the station layout requirements. It solves the problem that the dual-channel battery exchange station in the prior art cannot meet the actual station layout requirements when the size of the target installation area along the direction perpendicular to the extension direction of the battery exchange channel is limited.

[0040] It should be noted that the charging compartment 3 includes a battery 4 placement position and a charger, the charger is connected to the battery 4 placement position, the battery 4 placement position can store the battery 4, and the charger can charge the battery 4 placed on the battery 4 placement position.

[0041] In this embodiment, the extension direction of the battery exchange channel is made parallel to the edge of the corresponding equipment area 1, which is beneficial to reducing the distance between the battery exchange channel and the equipment area 1 and making the structure of the battery exchange station more compact.

[0042] In some embodiments, the two edges of the equipment area 1 corresponding to the two battery exchange channels are perpendicular to each other. In this case, the extension directions of the two battery exchange channels are perpendicular to each other.

[0043] In other embodiments, the two edges of the equipment area 1 corresponding to the two battery-exchanging channels are set at an obtuse angle. In this case, the extension directions of the two battery-exchanging channels are set at an obtuse angle.

[0044] In some other embodiments, the two edges of the equipment area 1 corresponding to the two battery exchange channels are set at an acute angle. In this case, the extension direction of the two battery exchange channels is set at an acute angle.

[0045] The shape of the device area 1 can be a polygonal area such as a triangle area, a quadrilateral area, a pentagonal area, etc.

[0046] In the embodiment of the utility model, the equipment area 1 is set as a quadrilateral area, the equipment area 1 has four edges, and two battery exchange channels are set. The two battery exchange channels correspond to two adjacent edges of the equipment area 1, and the battery exchange device 2 can be set at the corner position where the two edges intersect. The charging compartment 3 is distributed along the other two adjacent edges of the equipment area 1.

[0047] Detection devices are provided on the sides of the two battery-exchanging channels, by which it is possible to detect whether there is a vehicle 13 to be replaced with a battery and the parking position of the vehicle 13 to be replaced with a battery, so that the battery-exchanging device 2 can grab the battery 4 in a low-power state on the vehicle 13 to be replaced with a battery or release the battery 4 in a fully-charged state to the vehicle.

[0048] The remaining edges of the device area 1 are straight lines. When the charging compartments 3 are distributed along the remaining edges of the device area 1 , they can be distributed in straight lines along the edges, or they can be appropriately distributed in arc shapes.

[0049] In this embodiment, the charging compartment 3 is distributed along an arc, and the center of curvature of the arc and the battery swap device 2 are located on the same side of the charging compartment 3, which can facilitate the battery swap device 2 to grab and release the battery 4, shorten the transportation distance of the battery swap device 2 to the battery 4, and is conducive to improving the battery swap efficiency.

[0050] In some embodiments, the arc is a circular arc, and when the charging compartment 3 is distributed along the circular arc, the centers of curvature of each segment of the circular arc coincide, which is called the center of the circle. At this time, the charging compartment 3 is arranged radially around the center of the circle, and the battery swap device 2 can be installed at the center of the circle. The battery swap device 2 has a rotating mechanism, which can be aligned with the battery 4 in the charging compartment 3 or the battery 4 on the vehicle 13 to be swapped on the battery swap channel through rotation, reducing the displacement of the battery swap device 2, which is beneficial to improving the battery swap efficiency.

[0051] In other embodiments, the arc is a non-circular arc, such as an elliptical arc. At this time, while the charging compartments 3 are arranged radially, it is necessary to set a walking device 5 in the equipment area 1, set the battery exchange device 2 on the walking device 5, and use the walking device 5 to drive the battery exchange device 2 to move between at least one of the two battery exchange channels and the charging compartment 3. The walking device 5 can increase the battery exchange range of the battery exchange device 2, which is conducive to fully utilizing the space of the equipment area 1.

[0052] In this embodiment, the walking device 5 drives the battery exchange device 2 to move between one of the battery exchange channels and the charging compartment 3. Figure 1 and Figure 2 , the two battery-exchanging channels are the first battery-exchanging channel 16 and the second battery-exchanging channel 17. The walking device 5 drives the battery-exchanging device 2 to move between the second battery-exchanging channel 17 and the charging compartment 3. The battery-exchanging device 2 can approach or move away from the second battery-exchanging channel 17, which can facilitate battery-exchanging for the vehicle 13 to be replaced on the second battery-exchanging channel 17. When the extension direction of the first battery-exchanging channel 16 is perpendicular to the extension direction of the second battery-exchanging channel 17, by displacing the battery-exchanging device 2 between the second battery-exchanging channel 17 and the charging compartment 3, it is equivalent to adjusting the position of the battery-exchanging device 2 along the extension direction of the first battery-exchanging channel 16, thereby reducing the accuracy requirements for the parking position of the vehicle 13 to be replaced on the first battery-exchanging channel 16, which is beneficial to improving the battery-exchanging efficiency.

[0053] It should be noted that when the battery swap station provided by the embodiment of the utility model is in operation, both battery swap channels can be used for battery swap. During operation, the charging compartment 3 can be managed by zoning, such as dividing the charging compartment 3 into a first charging compartment area 14 and a second charging compartment area 15, the area close to the first battery swap channel 16 is the first charging compartment area 14, and the area close to the second battery swap channel 17 is the second charging compartment area 15. When the vehicle 13 to be replaced with a battery is parked in the first battery swap channel 16, the battery swap device 2 can be controlled to preferentially grab the battery 4 in the first charging compartment area 14 or the battery swap device 2 can be controlled to preferentially release the battery 4 to the first charging compartment area 14. When the vehicle 13 to be replaced with a battery is parked in the second battery swap channel 17, the battery swap device 2 can be controlled to preferentially grab the battery 4 in the second charging compartment area 15 or the battery swap device 2 can be controlled to preferentially release the battery 4 to the second charging compartment area 15. In this way, it is beneficial to reduce the time required for the battery swap device 2 to rotate, and it is beneficial to improve the efficiency of battery swapping.

[0054] When one of the battery exchange channels is needed to park the faulty vehicle for maintenance, the faulty vehicle can be parked on the second battery exchange channel 17. The vehicle 13 to be replaced is parked on the first battery exchange channel 16, and the battery exchange device 2 preferentially grabs the fully charged battery 4 in the charging compartment 3 that is closer to the first battery exchange channel 16.

[0055] The walking device 5 can be set to a structural form in which a walking wheel driven by a motor cooperates with a track, or it can be set to a structural form in which it slides under the drive of an electric cylinder, a hydraulic cylinder, a gear rack transmission mechanism, a sprocket chain transmission mechanism or a screw nut transmission mechanism. The specific structure of the walking device 5 will not be repeated here.

[0058] The translation mechanism is arranged on the slewing mechanism, and the slewing mechanism is used to drive the translation mechanism to slew around the vertical axis, so as to adjust the direction of the fork arm mechanism.

[0059] The lifting mechanism is arranged on the translation mechanism, and the translation mechanism is used to drive the fork arm mechanism to move in the horizontal direction, so as to realize the horizontal displacement of the fork arm mechanism, so as to realize the forking action of the battery 4 .

[0060] In a specific embodiment, the slewing mechanism includes a base 8, a slewing seat 9 and a slewing drive assembly, wherein the base 8 is arranged on the walking device 5, the slewing seat 9 is rotatably connected to the base 8 through a slewing bearing, the slewing axis of the slewing bearing is arranged in the vertical direction, and the slewing drive assembly is used to drive the slewing seat 9 to rotate relative to the base 8. The slewing drive assembly can be, but is not limited to, a gear transmission structure driven by a motor.

[0061] The lifting mechanism includes a support frame 10, a mobile support 11 and a lifting drive assembly 12. The end of the support frame 10 is slidably connected to the swivel seat 9, and the sliding direction of the support frame 10 relative to the swivel seat 9 is arranged in the horizontal direction. The mobile support 11 is slidably connected to the support frame 10, and the sliding direction of the mobile support 11 relative to the support frame 10 is arranged in the vertical direction. The lifting drive assembly 12 is used to drive the mobile support 11 to slide relative to the support frame 10.

[0062] The translation mechanism includes a translation drive assembly, which is used to drive the support frame 10 to slide relative to the swivel seat 9. The translation drive assembly can be, but is not limited to, a gear rack transmission structure driven by a motor.

[0063] In this embodiment, the fork arm mechanism includes a pair of forks 7, the extension directions of the pair of forks 7 are parallel, the pair of forks 7 are spaced apart in the horizontal direction, and the battery 4 can enter the space between the pair of forks 7. The battery 4 is provided with protrusions 6 on two opposite sides thereof, and when the battery 4 is located between the pair of forks 7, the forks 7 are located below the protrusions, and the forks 7 can abut against the lower surface of the protrusions 6.

[0064] The lifting mechanism is used to drive the fork arm mechanism to rise, and the battery 4 can be lifted up through the interaction between the fork arm 7 and the protrusion 6, so that the battery 4 can be forked.

[0065] At least two protrusions 6 are disposed on one side of the battery 4 . The at least two protrusions 6 interact with a fork arm 7 at the same time, which can prevent the battery 4 from turning over and ensure the relative stability of the battery 4 and the fork arm 7 .

[0069] It can be understood that the battery swap device 2 itself has two fork arm mechanisms, so that the battery swap station can use the time when the vehicle arrives, parks, and leaves during operation, which is conducive to shortening the battery swap time and improving the battery swap efficiency. Moreover, the two fork arm mechanisms serve as backup for each other, which can avoid the impact of equipment failure on the operation of the battery swap station to the greatest extent possible and ensure the reliable operation of the system.

Moreover, the two battery swap channels are arranged non-parallel, which belongs to a new layout form. When the size of the target installation area in the direction perpendicular to the extension direction of the battery swap channel is limited, it can well meet the actual station layout needs.
