[0030] Example

[0031] Combination Figures 1 to 6 This embodiment provides a compact and safe battery swap station, including a charging platform 10 and a battery swap platform 20, wherein the charging platform 10 is connected to the battery swap platform 20, and the battery swap platform 20 is provided with a first passage component 201 for vehicles to pass through and a second passage component 202 for pedestrians to pass through. The direction of vehicle passage is as follows: Figure 2 In the direction indicated by the arrow B, the direction of the first pass component 201 is parallel to the direction of the second pass component 22, the first pass component 201 is arranged between the charging platform 10 and the second pass component 202, and an escape device 30 is also provided on the side of the second pass component 202 away from the first pass component 201.

[0032] It should be noted that the “platform” in the specification, claims and drawings of the present application should not be narrowly understood as a flat tabletop, but should be broadly understood as a workbench with various deformations under specific circumstances.

[0033] like Figure 1 and Figure 2 As shown, the charging platform 10 includes a battery pack rack 3, a charger 2, a stacker 7 and a battery pack cache device 4; the battery pack rack 3 is used to store battery packs, including fully charged battery packs and low-charged battery packs; the charger 2 is connected to the battery pack rack 3, and the charger 2 is used to charge the low-charged battery packs stored on the battery pack rack 3; the stacker 7 is used to store and retrieve battery packs, including removing the battery packs from the battery pack rack 3 and placing them in the battery pack cache device 4, and transferring the battery packs replaced by the battery swap platform 20 from the battery pack cache device 4 and storing them in the battery pack rack 3; the battery pack cache device 4 is arranged on a side of the charging platform 10 close to the battery swap platform 20, and the charging platform 10 and the battery swap platform 20 exchange battery packs through the battery pack cache device 4, and the direction of battery pack replacement is as shown in FIG. Figure 2 As shown by arrow A.

[0034] The charging platform 10 is also provided with a guide rail 71, and the stacker 7 can move back and forth along the guide rail 71. The setting direction of the guide rail 71 is parallel to the vehicle passing direction of the first passing component 201. The charger 2 and the battery pack cache device 4 are both arranged on the side of the guide rail 71 close to the battery exchange platform 20, that is, the charger 2 and the battery pack cache device 4 are arranged on the same side of the guide rail.

[0035] The battery pack frame 3 includes a first battery pack frame 31 and a second battery pack frame 32, and the first battery pack frame 31 and the battery pack frame 32 are respectively arranged on both sides of the guide rail 71. Specifically, the first battery pack frame 31 is arranged on the side of the guide rail 71 close to the battery exchange platform 20, that is, the first battery pack frame 31 and the charger 2 and the battery pack cache device 4 are located on the same side of the guide rail 71, and the charger 2 is arranged between the first battery pack frame 31 and the battery exchange platform 20, and the second battery pack frame 32 is arranged on the side of the guide rail 71 away from the first battery pack frame 31.

[0036] It should be noted that in order to make full use of the space in the battery swap station and increase the number of battery packs that can be stored, in the embodiment of this specification, the first battery pack rack 31 is provided with one rack, and the second battery pack rack 32 is provided with three racks. The rack of the first battery pack rack 31 and the rack of the second battery pack rack 32 are both provided with multiple battery pack storage layers, and the three racks of the second battery pack rack 32 are evenly distributed on the side of the guide rail 71 away from the battery swap platform 20.

[0037] Of course, the second battery pack rack 32 may also be provided with other multiple racks, and there is no limitation on the size of the racks of the first battery pack rack 31 and the second battery pack rack 32. The number of battery packs stored in the second battery pack rack 32 may be several times more than the number of battery packs 32 stored in the first battery pack rack 31.

[0038] In the embodiment of this specification, the charging platform 10 is also provided with an equipment maintenance device 8 and a control device 9. Figure 1 As shown, the equipment maintenance device 8 is arranged between the guide rail 71 and the battery exchange platform 20, the control device 9 is arranged between the equipment maintenance device 8 and the battery exchange platform 20, and the equipment maintenance device 8 and the control device 9 are both arranged on the side of the battery pack cache device 4 away from the first battery pack rack 31, that is, one side of the equipment maintenance device 8 is adjacent to the battery pack cache device 4; when the stacker 7 moves along the guide rail 71, the equipment maintenance device 8 can also be adjacent to the stacker 7, that is, the length and setting direction of the guide rail 71, since the charger 2 is arranged between the first battery pack rack 31 and the battery exchange platform 20 and the control device 9 is arranged between the equipment maintenance device 8 and the battery exchange platform 20, the movement of the stacker 7 is not affected by the charger 2 and the control device 9, that is, the stacker 7 can move smoothly in any one of the battery pack rack 3, the battery pack cache device 4 and the equipment maintenance device 8.

[0039] In the embodiments of this specification. Since the equipment maintenance device 8 and the battery pack cache device 4 are adjacent, the battery pack cache device 4 can be inspected and maintained at the equipment maintenance device 8. Similarly, when the stacker 7 moves to one end close to the equipment maintenance device 8, the stacker 7 can be inspected and maintained, which is beneficial to ensure the operation of the battery swap station. When the stacker 7 transports the damaged battery pack to the equipment maintenance device 8, the equipment maintenance device 8 can also be used to inspect the battery pack to increase the service life of the battery pack. Preferably, in the embodiments of this specification, the length and width of the equipment maintenance device 9 should be greater than the length and width of the battery pack, and the height of the equipment maintenance device 8 should be higher than the position of the lower dead point of the fork of the stacker 7 to accommodate maintenance work.

[0040] When the equipment maintenance device 8 has no maintenance tasks, the equipment maintenance device 8 can also serve as a rest area for station staff.

[0041] When there are bad battery packs and other battery packs that can no longer be used in the battery swap station, if such battery packs are stored on the battery pack rack 3 for a long time, it will inevitably occupy the limited battery pack storage space in the battery swap station. Therefore, the bad battery packs need to be replaced out of the battery swap station. In addition, new battery packs need to be replenished from outside the station. At this time, the equipment maintenance device 8 can act as an intermediary for battery pack replacement: the stacker 7 obtains the battery packs that need to be replaced, and transfers such battery packs to the equipment maintenance device 8, so that the forklift outside the station can obtain and transport such battery packs out of the battery swap station; when the forklift outside the battery swap station transports the new battery pack to the equipment maintenance device 8, the stacker 7 can store the new battery pack on the battery pack rack 3 to complete the update of the battery packs in the battery swap station.

[0042] The control device 9 includes a control machine, which can be used to control the movement of the stacker 7 and monitor the number and power of the battery packs on the battery pack rack 3, etc.

[0043] The battery exchange platform 20 is provided with a vehicle lifting device 1, which is used to lift the vehicle. Figure 2 When the vehicle moves to the battery replacement position in the direction indicated by the middle arrow B, the vehicle lifting device 1 lifts the vehicle to a certain height so that the battery pack to be replaced on the vehicle chassis can be removed and the fully charged battery pack is installed on the vehicle chassis, and the removed battery pack is placed in the battery pack cache device 4 to achieve battery replacement. During this battery replacement process, the fully charged battery pack can be loaded in advance in the battery pack cache device 4 to shorten the time required for battery pack replacement and improve the battery replacement efficiency. It should be noted that during the battery replacement process, the battery pack used for replacement is not limited to a fully charged battery pack, but can also be a battery pack that stores other charges to meet the needs of different car owners.

[0044] like Figure 2 As shown, in the embodiment of the present specification, the vehicle lifting device 1 includes a first vehicle lifting device 11 and a second vehicle lifting device 12, and two of the first vehicle lifting device 11 and the second vehicle lifting device 12 are provided, and the two first vehicle lifting devices 11 are located between the charging platform 10 and the battery exchange platform 20, and the two second vehicle lifting devices 12 are located at the second passage component 201.

[0045] The two first vehicle lifting devices 11 are at least partially disposed in the charging platform 10, so that the distance between the first vehicle lifting device 11 and the second vehicle lifting device 12 is increased, thereby not only providing sufficient space for vehicles to pass, but also leaving enough space for pedestrians to pass. Figure 4 As shown, the traffic needs of the driver and rear passengers during battery replacement are met, and the distance between the two first vehicle lifting devices 11 is greater than the size of the battery pack, which is convenient for the battery pack to be lifted along the Figure 2 Replace in the direction indicated by arrow A.

[0046] The first passage component 201 is further provided with an uphill pad 5 and a downhill pad 6, which are respectively arranged at two ends of the first passage component 201, and are used to assist vehicles in passing.

[0047] The escape device 30 is arranged between the two second vehicle lifting devices 12. Figure 5 As shown, the escape device 30 is provided with an escape door 301 , and the escape door 301 is provided with a handle 302 for opening the escape door 301 , and the escape door 301 is also provided with an escape mark.

[0048] It should be noted that the vehicle in the embodiment of this specification is a vehicle with the driver's seat on the left, and the vehicle's travel direction in the first passage component 201 is as follows: Figure 2 As shown by the arrow B in the middle; the escape device 30 is on the side close to the driver's seat to facilitate the driver's escape. For a vehicle with the driver's seat on the right, by driving in the direction opposite to the direction indicated by the arrow B, the original downhill pad 6 acts as an uphill pad, and the original uphill pad 5 acts as a downhill pad, and the escape device 30 is located on the side close to the driver's seat.

[0049] Optionally, in the embodiment of this specification, the escape door 301 is connected to the battery swap station in a hinged manner, such as Figure 6 As shown, the bottom end of the escape door 301 is hinged to the battery swap station. When the escape door 301 needs to be opened, the escape door 301 can be flipped outward and fall on the ground. It can be seen from the uphill pad 5 and the downhill pad 6 that there is a certain height difference between the vehicle battery swapping place of the battery swap platform 20 and the ground. After the escape door 301 falls on the ground, this height difference is alleviated to form an escape passage for escape.

[0050] The embodiment of this specification provides a compact and safe battery swap station, which can be Figure 3The method shown in the figure is to build: including a first container 100, a second container 200, a third container 300 and a fourth container 400, wherein the first container 100, the second container 200 and the container 300 are sequentially arranged side by side on one side of the fourth container 400. One frame of the first battery pack frame 31 and the second battery pack frame 32 is arranged in the first container 100, the battery pack cache device 4 and one frame of the second battery pack frame 32 are arranged in the second container 200, the last frame of the second battery pack frame 32, the equipment maintenance device 8 and the control device 9 are arranged in the third container 300, the second container 200 is connected with the first container 100 and the third container 300, and the guide rail 71 passes through the first container 100, the second container 200 and the third container 300. The first passage component 201 and the second passage component 202 are arranged in the fourth container 400, and the uphill pad 5 and the downhill pad 6 are respectively arranged at both ends of the fourth container 400. The fourth container 400 is connected to the second container 200 and is used for replacing the battery pack through the battery pack cache device 4 .

[0051] It should be noted that the above is only one way of building the compact and safe battery swap station described in the present invention. In addition to this way, there are of course other ways of building.

[0052] The compact and safe battery swap station provided by the present invention realizes a reasonable layout of different functional areas of the battery swap station by at least partially arranging the first vehicle lifting device in the charging platform and arranging the charger in the space between the battery rack and the battery swap platform, so that the area occupied by the battery swap station is minimized, the battery pack storage space is increased, and the cost of the battery swap station is reduced;

[0053] The compact and safe battery swap station is provided with an equipment maintenance device, which can perform maintenance on the battery pack, stacker and battery pack buffer device in the battery swap station, which is beneficial to prolonging the service life of the battery pack, realizing the self-inspection function of the battery swap station, and ensuring the normal operation of the battery swap station;

[0054] The equipment maintenance device can also act as an intermediary between the battery swap station and the external battery pack update. Therefore, there is no need to set up other areas to realize the battery pack update function, which is conducive to simplifying the configuration of the battery swap station and reducing the construction cost of the battery swap station;

[0055] In addition, the equipment maintenance device can be used as a rest area for station staff when there is no maintenance task, and its design is humane.
