Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and more specifically, to a small battery replacement station. Background Art

[0002] As new energy technologies become increasingly mature, battery-swappable vehicles are gradually coming into view. Existing technologies provide battery-swappable stations for battery-swappable vehicles. These stations typically include a box shell, a battery holder, and a battery-swappable robot. Both the battery holder and the battery-swappable robot are located within the cavity of the box shell. The battery holder allows for convenient placement of battery boxes. The battery-swappable robot has a telescopic arm that can extend or retract to the box shell to transfer battery boxes between battery-swappable vehicles inside and outside the station. The battery-swappable stations available on the market are equipped with transfer stations and a large number of battery holders. The transfer stations and the battery holders are arranged in a straight line. This single-line arrangement results in a longer station length, higher requirements for station construction space, and higher costs for a single station, making it difficult to promote.

[0047] See also Figures 1 to 4 As shown, an embodiment of the present application provides a small battery swap station, comprising: a box shell 1, a transfer seat 3, a battery swap robot 4 and four battery holders 2. The box shell 1 has a cavity, and the four battery holders 2 are all arranged in the cavity. The four battery holders 2 are arranged in two rows and two columns. The transfer seat 3 is arranged in the cavity, and the transfer seat 3 is located between two adjacent battery holders 2. The battery swap robot 4 is arranged in the box shell 1. The battery swap robot 4 has a telescopic arm 42, and a battery gripper 43 is provided on the telescopic arm 42. The telescopic arm 42 can drive the battery gripper 43 to extend or retract into the cavity to transport the battery box.

[0048] The four battery holders 2 of the small battery swap station of the present application are arranged in two rows and two columns, and the transfer seat 3 is arranged between the four battery holders 2, so that the internal space of the battery swap station is utilized for charging. The small battery swap station of the present application has a small number of battery holders 2, and the entire battery swap station is small in size and fully functional. It can be flexibly arranged in a small space area, which greatly reduces the cost of a single battery swap station and is conducive to the promotion of battery swap stations.

[0049] In some possible embodiments, the four battery holders 2 are divided into two battery holder groups, each battery holder group includes two battery boxes arranged in sequence along the telescopic direction of the telescopic arm 42, the two battery holder groups are arranged in sequence along the direction perpendicular to the telescopic arm 42, and the transfer seat 3 is located between the two battery holder groups.

[0050] An upper cavity 11 and a lower cavity 12 may be provided in the box shell 1 , wherein the battery holders 2 are provided in the upper cavity 11 , and a transfer seat 3 is provided in the lower frame. The projections of the battery holders onto the bottom surface of the lower cavity 12 are located on both sides of the transfer seat 3 .

[0051] In some possible implementation schemes, two guide rails 5 are provided in the cavity of the box shell 1, and the two guide rails 5 are respectively provided at both ends of the battery seat group along the arrangement direction of each battery seat 2, and the guide rails 5 extend in a direction parallel to the arrangement direction of the two battery seat groups. The battery-swapping robot 4 has two side frames 41, and the two side frames 41 are respectively slidably connected to the corresponding guide rails 5, and the telescopic arms 42 are connected to the side frames 41. A walking mechanism 413 can be provided on the battery-swapping robot 4, and the walking mechanism 413 can drive the side frames 41 to translate along the guide rails 5, so that the battery-swapping robot walks to different battery seat groups. The walking mechanism 413 may include a driving member and a track-matching wheel that is matched with the driving member for transmission, and the track-matching wheel can roll along the guide rails 5.

[0052] In some possible implementation schemes, the small battery swap station includes a synchronous transmission mechanism 6, and the two side frames 41 are both provided with track-matching wheels, which are slidably connected to the corresponding guide rails 5. The synchronous transmission mechanism 6 is arranged in the cavity, and the synchronous transmission mechanism 6 is respectively connected to the two side frames 41 for transmission. The movement of one side frame 41 can drive the other side frame 41 to move synchronously through the synchronous transmission mechanism 6.

[0053] See also Figure 3 As shown, the two side frames 41 of the battery-swapping robot 4 of the present application are located on both sides of the two battery holders 2 of the same battery holder group. The distance between the two side frames 41 is relatively large, and the driving component (such as a motor or hydraulic motor) is only provided on one of the side frames 41. Therefore, the problem of asynchronous movement is prone to occur between the two side frames 41. The embodiment of the present application can make the two side frames 41 move synchronously by providing a synchronous transmission mechanism 6, thereby improving the movement accuracy of the battery-swapping robot 4.

[0054] In some possible embodiments, the synchronous transmission mechanism 6 includes a first transmission device 61 and two second transmission devices 62, the two second transmission devices 62 are respectively located on both sides of the cavity along the telescopic direction of the telescopic arm 42, the two second transmission devices 62 are respectively connected to the corresponding side frames 41, the first transmission device 61 is located between the two second transmission devices 62, and the two ends of the first transmission device 61 are respectively connected to the two second transmission devices 62.

[0055] Among them, see Figure 3 and Figure 4 As shown, the second transmission device 62 includes two synchronous pulleys 621 and a synchronous belt 622 mounted on the synchronous pulleys 621. The synchronous pulleys 621 are rotatably mounted on a structure on the housing. The side frame 41 is connected to the synchronous belt 622. The two ends of the first transmission device 61 are respectively connected to the synchronous pulleys 621 or synchronous belt 622 of the corresponding second transmission device 62. When one side frame 41 moves, it can drive the synchronous belt 622 of the corresponding second transmission device 62 to move. The synchronous belt 622 can drive the first transmission device 61 to rotate via the synchronous pulleys 621. The first transmission device 61 then drives the synchronous belt 622 of the second transmission device 62 corresponding to the other side frame 41 to rotate. The synchronous belt 622 drives the corresponding side frame 41 to move.

[0056] In some possible embodiments, two connecting seats 411 are provided on the side frame 41. The synchronous belt 622 is a strip-shaped body that is sleeved over the two synchronous pulleys. The ends of the synchronous belt 622 are respectively connected to the two connecting seats 411. The synchronous belt 622 is not a closed loop, but a strip-shaped body, with its ends respectively connected to the two connecting seats 411 on the side frame 41. The synchronous belt 622 can be a toothed belt, or it can be replaced by a chain or other structure.

[0057] In some possible implementation schemes, an articulated joint is provided on the connecting seat 411 , and an articulated fitting 6221 is provided at the end of the synchronous belt 622 , and the articulated fitting 6221 and the articulated joint are rotatably connected.

[0058] The first transmission device 61 includes a rotating shaft, the extending direction of the rotating shaft is perpendicular to the synchronous belt 622 , and both ends of the rotating shaft are respectively connected to corresponding synchronous pulleys 621 on the two second transmission devices 62 .

[0059] The distance between the two side frames 41 is relatively large. If the first transmission device 61 only has a single rotating shaft, the rotating shaft would be too long and easily deformed, hindering accurate power transmission. In this embodiment, the rotating shaft comprises multiple short shafts 611, each of which is arranged sequentially. The two short shafts 611 at each end are connected to corresponding synchronous pulleys 621 on the two second transmission devices 62. Adjacent short shafts 611 are connected by universal joints 612. By configuring the rotating shaft as multiple short shafts 611, the length of each shaft is reduced, facilitating production, transportation, and assembly. In this embodiment, adjacent short shafts 611 are connected by universal joints 612, which enable variable-angle power transmission. Universal joints 612 offer numerous advantages: high angular adaptability, smooth power transmission, durability and reliability, easy installation and maintenance, adaptability to various operating environments, complete constant velocity, high transmission efficiency, compact structure, vibration and shock absorption capabilities, large swing angle range, high dynamic balancing accuracy, and easy installation.

[0060] In some possible implementations, see Figure 1 As shown, the battery swap station includes a door body 8 and a door drive mechanism 9. The box shell 1 has a door opening 13 connected to the upper cavity 11. The door body 8 is movably arranged on the outer wall of the box shell 1. The door drive mechanism 9 is arranged on the box shell 1. The door drive mechanism 9 is transmission-connected to the door body 8. The door drive mechanism 9 can drive the door body 8 to slide along the box shell 1 to close or open the door opening 13.

[0061] The door driving mechanism 9 may be an electric push rod, a motor or a telescopic cylinder, etc.

[0062] The door opening 13 can avoid the telescopic arm 42 of the battery-swapping robot 4, so that the telescopic arm 42 of the battery-swapping robot 4 can extend out of the door opening 13 or retract from the door opening 13 into the upper cavity 11. The battery swap station can be roughly a rectangular parallelepiped structure, and a door opening 13 can be set on one side of the shell 1 of the battery swap station. The battery swap station of the present application has a small volume and a small shell wall area. When the door body 8 is set inside the upper cavity 11, the sliding stroke of the door body 8 is too small to meet the requirement of fully opening the door opening 13.

[0063] The embodiment of the present application arranges the door body 8 outside the box shell 1, which does not occupy the space of the upper cavity 11, and the box shell 1 does not interfere with the movement of the door body 8, which is conducive to increasing the stroke of the door body 8.

[0064] In some possible implementation schemes, the battery swap station includes a canopy 10 , which is connected to the box shell 1 , forming a battery swap channel between the canopy 10 and the box shell 1 , and a doorway 13 connecting the battery swap channel and the upper cavity 11 .

[0065] The battery-swap vehicle can be put into the battery-swap channel and located within the activity range of the battery-swap robot 4, making it convenient to cooperate with the battery-swap robot 4 to perform the battery-swap task.

[0066] A sling can be set on the telescopic arm 42 of the battery-exchanging robot 4, and the battery gripper 43 is connected to the sling. The sling has a lifting rope, and the battery gripper 43 is connected to the lifting rope. The sling can drive the battery gripper 43 to move up and down by retracting and releasing the lifting rope. The sling can be a winch.

[0067] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
