[0002] New energy electric vehicles are vehicles that use batteries to power their vehicles. However, the battery charging time of electric vehicles is long and the driving range is short, which affects the use of electric vehicles. In order to improve the endurance of new energy vehicles, battery swap stations are built to directly replace the charged batteries of the vehicles at the battery swap stations, so that the new energy vehicles can quickly restore power, thereby improving the endurance of new energy vehicles.

[0003] Existing battery swap stations usually use lifting equipment to remove the batteries in the station, remove the old batteries and install new batteries for the cars. However, in order to ensure the normal storage of the batteries in the station, the temperature of the battery storage area in the station is kept suitable and stable. During the transportation of the lifting equipment, cold air from the outside can easily enter the battery storage area, increasing the constant temperature energy consumption.

[0004] In the prior art, the car is driven into the battery exchange chamber, the car is lifted by a lifting equipment, and the battery is moved from the storage chamber to the battery exchange chamber by a moving mechanism, and the battery at the bottom of the car is replaced. In this method, the car needs to be lifted, and the battery cannot be replaced while it is moving, which increases the battery replacement time and reduces the battery replacement efficiency. A retractable pick-and-place device is used to first remove the old battery and move it back to the storage chamber, and then replace it with a new battery after taking it. In this method, the removal of the old battery and the installation of the new battery cannot be completed at the same time, which increases the battery replacement cycle. Summary of the invention

When the rotating assembly is working, the fixed rod drives the push rod to push the second baffle out and then retract it, so that when the rotating assembly rotates the battery swap mechanism, the second baffle is prevented from hindering the rotation of the battery swap mechanism. The second baffle cooperates with the first baffle to form an anti-fall space, which protects the battery swap mechanism inside. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] First, the second motor 9 is started, and the output end of the second motor 9 drives the fourth lead screw 34 to rotate. The rotation of the fourth lead screw 34 drives the third slider 32 to slide, and the U-shaped mounting plate 35 is moved to the top of the battery compartment 1 through the third slider 32. At this time, the fastener 40 at the output end of the first motor 8 fixes the third lead screw 33, and then the telescopic block 39 in the third slider 32 is retracted;

[0058] Then, the first motor 8 is started, and the output end of the first motor 8 is operated to rotate the third lead screw 33, and the rotation of the third lead screw 33 drives the first slider 7 to slide, and the U-shaped mounting plate 35 is driven to move horizontally through the first slider 7, so that the U-shaped mounting plate 35 moves to the front of the charging unit 6 where the battery pack is placed;

[0059] Extend the telescopic block 39 in the third slider 32 to insert it into the groove of the U-shaped mounting plate 35 to fix the U-shaped mounting plate 35;

[0060] Then, the clamping assembly drives the clamping plate 37 to penetrate into the interior of the charging unit 6 through the electric telescopic rod 36, and then the clamping assembly is started. After the battery pack at that position is clamped by the clamping plate 37, the battery pack is taken out by contracting the electric telescopic rod 36.

[0061] After the battery pack is taken out, the fastener 40 is loosened, and the second motor 9 is started again, so that the fourth lead screw 34 rotates, and the U-shaped mounting plate 35 is driven to move downward to the bottom of the battery compartment 1 through the third slider 32;

[0062] At the same time, the third motor 10 on the battery compartment 1 can be started to drive the second lead screw 12 to rotate, and the rotation of the second lead screw 12 drives the third support plate 24 to move, so that the entire battery replacement system on the third support plate 24 is moved horizontally to just below the U-shaped mounting plate 35;

[0063] When the U-shaped mounting plate 35 moves to the top of the gripping system, the clamping assembly releases the clamping plate 37, so that the battery pack is placed on the battery replacement mechanism 15;

[0064] Release the connection between the fixed block 17 and the embedded block 18 at the output end of the third motor 10 on the battery compartment 1, and then start the fourth motor 13 to rotate the first screw 11, thereby driving the second slider 14 to move, and finally moving the entire battery swap system to the bottom of the battery swap platform 3, and connecting the fixed block 17 and the embedded block 18 at the output end of the third motor 10 in the battery swap platform 3;

[0065] During the entire process of moving and placing the battery pack, the entire process is moved by the lead screw, which can accurately convert the rotational motion of the motor into linear motion. This conversion mechanism ensures the position accuracy of the battery pack during placement, reduces errors and deviations, and avoids jitter and shaking during movement. This is especially important for the placement of battery packs that require high-precision positioning, ensuring that the battery pack can be accurately placed in the specified position. Compared with other transmission methods, the lead screw guide system uses mechanical transmission, which is more reliable and durable, which reduces the failure rate of the equipment during movement and improves the safety of the entire battery pack placement process;

[0066] When the charging unit 6 is located on the left side of the battery compartment 1, the battery pack can be placed on the battery exchange mechanism 15 of the first support plate 20. After the battery pack is placed, the third motor 10 is started to drive the third support plate 24 to move through the second lead screw 12, thereby driving the first support plate 20 and the second support plate 22 to move, and the battery exchange mechanism 15 corresponding to the second support plate 22 is moved to the horizontal support frame under the sliding door 4, and then the fourth motor 13 is started to drive the third support plate 24 to move through the first lead screw 11 and the second slider 14, and finally the battery exchange mechanism 15 on the second support plate 22 is aligned with the bottom of the sliding door 4;

[0067] At this time, the lifting device 30 under the second support plate 22 is started, so that the lifting platform on the lifting device 30 drives the second support plate 22 to move upward, thereby driving the battery exchange mechanism 15 on the second support plate 22 to move upward, and at the same time the sliding door 4 is opened, and the battery exchange mechanism 15 will remove the battery pack at the bottom of the car. After the battery pack is removed, the lifting device 30 starts to descend and returns to the inside of the battery exchange platform 3;

[0068] At this time, the third motor 10 is started again to move the entire battery replacement system, so that the battery replacement mechanism 15 on the first support plate 20 is aligned with the bottom of the sliding door 4. At this time, another lifting device 30 is started again to move the first support plate 20 upward. The battery replacement mechanism 15 on the first support plate 20 installs the new battery pack to the bottom of the car. After installation, the lifting device 30 is started again to lower the first support plate 20, and then the sliding door 4 is closed, and the battery replacement is completed;

[0069] When the charging unit 6 is located on the right side of the battery compartment 1, the battery pack can be placed on the battery replacement mechanism 15 of the second support plate 22, so that the battery replacement mechanism 15 on the first support plate 20 is aligned with the bottom of the sliding door 4, and the battery pack of the vehicle is removed by the battery replacement mechanism 15 on the first support plate 20, and a new battery pack is installed on the battery replacement mechanism 15 on the second support plate 22;

[0070] Due to the existence of the battery swap platform 3, the battery swap system does not need to lift the car when moving or lifting, and the battery pack can be removed and installed when the car is stationary, thereby greatly shortening the battery swap time and improving the battery swap efficiency; for car owners, the battery swap system without lifting the car provides a more convenient and comfortable battery swap experience. Car owners do not need to wait for the vehicle to perform complicated lifting operations, and only need to park the vehicle at a designated location to complete the battery swap process; this stop-and-go method not only saves time, but also reduces the waiting anxiety of car owners, and improves overall user satisfaction;

[0071] Moreover, the entire battery swap system adopts a symmetrical design, so that the left and right sides are consistent in structure and function. Whether it is the left or right side, the same battery swap operation can be performed without adjusting or reconfiguring the equipment;

[0072] In addition, after the battery replacement mechanism 15 removes the battery pack, it is not necessary to put down the old battery pack and then take up the new battery pack for installation like other devices. Instead, the positions of the old and new battery packs are controlled by a simple structure of a lead screw to achieve rapid and accurate replacement of the old and new battery packs. This seamless connection reduces the waiting time and human intervention in the battery replacement process, significantly improves the battery replacement efficiency, shortens the vehicle's stay time, and thus enhances the convenience and economy of electric vehicle use.

[0073] Since the replacement of the old battery pack with the new one is fast and most of the operations are performed inside the battery replacement platform 3 and the battery compartment 1, the heat exchange caused by air circulation can be significantly reduced, which helps to keep the battery pack working within a stable temperature range, thereby extending the service life of the battery pack and maintaining its stable performance;

[0074] After installing a new battery pack in the car, the entire battery swap system is restored to its original state. At this time, the clamping device 26 is started to clamp the first support plate 20 and the second support plate 22 through the grooves on the first support plate 20 and the second support plate 22. Then, the sixth motor 31 is started to rotate the first support plate 20 and the second support plate 22 by 180°. At this time, the battery swap mechanism 15 equipped with the old battery pack will swap positions with another battery swap mechanism 15.

[0075] Then start the fifth motor 29 to rotate the first gear 21, thereby driving the second gear 23 to rotate, and finally causing the battery swapping mechanisms 15 on both sides to rotate 180° at the same time. At this time, the old battery pack on the battery swapping mechanism 15 will have the same direction as the new battery pack. In this way, when the clamping plate 37 puts the old battery pack back into the charging unit 6, there is no need to turn the direction again, and there is no need to spend extra time to adjust the direction of the battery pack during the battery swapping process, thereby shortening the battery swapping cycle. In addition, the design of automatically adjusting the direction of the battery pack reduces the need for manual operation, reduces the possibility of human error, and reduces the burden on staff, thereby further improving the efficiency and convenience of battery swapping.

[0076] The battery exchange system is also equipped with a first baffle 5 and a second baffle 16 to prevent the battery pack from falling off. When the first gear 21 drives the battery exchange mechanism 15 to rotate, the fixed rod 27 on the first gear 21 will also rotate accordingly, thereby driving the push rod 28 to push the second baffle 16 to both sides. This ensures that the battery exchange mechanism 15 is unobstructed on the rotation path and effectively avoids collision between the battery pack and the second baffle 16, and can provide necessary protection during the rotation process, thereby protecting the integrity of the battery pack and the battery exchange mechanism 15.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
