Description

Technical Field

[0001] This utility model relates to power batteries, and more specifically, to a replacement device for power batteries of various sizes. Background Technology

[0002] With the continuous improvement of battery technology, the technology of small electric aircraft has become increasingly mature and has been put into production and application. At present, there are two main ways to replenish the power of electric aircraft: direct charging and battery replacement. Battery replacement is more time-saving than direct charging and is becoming an indispensable method for electric aircraft.

[0003] Chinese Patent Announcement CN116161235A discloses a device for efficiently replacing the power battery of an electric aircraft. Its key technical features include: an AGV (Automated Guided Vehicle) body equipped with wheels; a power unit and control system within the AGV body; a lifting platform mounted on the top side of the AGV body; and two parallel workstation components on the lifting platform. One workstation component is used to remove empty batteries from the electric aircraft, while the other is used to install fully charged batteries onto the electric aircraft. A cover assembly is also provided on the lifting platform, covering one side of the two workstation components. The cover assembly and the lifting platform cooperate to form a battery storage space. The cover assembly has a positioning component connected to the control system. This positioning component monitors the position of the AGV body relative to the electric aircraft, allowing the control system to control the movement of the wheels and the lifting action of the lifting platform, thereby enabling the two workstation components to sequentially align with the battery replacement positions on the electric aircraft.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] As shown in the figure, a battery replacement device adaptable to multiple sizes includes a vehicle body 1, on which a rotating lifting platform 2 is provided. The upper surface of the rotating lifting platform 2 is provided with two sets of sliding components. Each set of sliding components is provided with a set of sliding drive components and a sliding table 29 slidably connected to it. The two sets of sliding components are symmetrically distributed around the center of the rotating lifting platform 2. Each sliding table 29 is provided with a set of battery contact components that can adapt to multiple sizes of power batteries. Each battery contact component is provided with four sets of guide components. A lifting component for lifting the rotating lifting platform 2 is provided inside the vehicle body 1. The lifting component is provided with a rotating component.

[0031] The vehicle body 1 can move the entire device to a designated location as needed. The sliding component and the sliding drive component work together to allow the slide table 29 to slide. The slide table 29 can deliver a fully charged power battery to the aircraft battery compartment or take the power battery out of the aircraft battery compartment. The battery abutment component can use power batteries of various widths to improve the overall adaptability of the device. The guide component can guide the power battery into the aircraft battery compartment or guide the power battery from the aircraft battery compartment to the slide table 29. The lifting component can lift and lower according to the position of the aircraft battery compartment. The rotating component can rotate the rotating lifting platform 2 180° so that the entire device only needs to be aligned with the battery installation position of the aircraft once to send the battery into the aircraft or retrieve the battery from the aircraft.

[0032] The sliding assembly includes slide rails 3 and sliders 4. There are two slide rails 3, which are set on the upper surface of the rotary lifting platform 2 and are symmetrically distributed about the center of the platform 29. There are several sliders 4, which are slidably connected to the two slide rails 3 and bolted to the lower surface of the platform 29. The slide rails 3 provide corresponding support for the installation of the sliders 4, and the sliders 4 enable the platform 29 to perform linear displacement.

[0033] The sliding drive assembly includes a sliding cylinder 5, a sliding connector 6, and a sliding mounting plate 7. The sliding connector 6 is mounted on the piston rod of the sliding cylinder 5, and its top bolt is fixed to the lower surface of the slide table 29. One side bolt of the sliding mounting plate 7 is fixed to the sliding cylinder 5, and its bottom bolt is fixed to the surface of the slide table 29.

[0034] The piston rod of the sliding cylinder 5 exerts a force on the sliding connector 6. The sliding connector 6 is fixed to the slide table 29 by bolts, which can drive the linear displacement of the slide table 29. It cooperates with the slider 4 of the slide rail 3 to make the whole sliding process more stable.

[0035] The battery contact assembly includes a contact plate 8, a contact motor 9, a contact screw 10, and a contact mounting plate 11. There are two contact plates 8, which are slidably connected to the upper surface of the slide table 29 and are symmetrically distributed around the center of the slide table 29. The contact motor 9 is rotatably connected to the contact screw 10, which passes through and is threaded to the top of the two contact plates 8. One end of the contact mounting plate 11 is bolted to the contact motor 9, and the other end is bolted to one of the contact plates 8.

[0036] The abutment motor 9 drives the abutment screw 10 to rotate, causing the two abutment mounting plates 11 to move away from or closer to each other, so as to accommodate power batteries of different widths. The abutment mounting plates 11 provide corresponding support for the installation of the abutment motor 9.

[0037] Two sliding connecting plates 12 are provided at the bottom of the abutment plate 8. The two sliding connecting plates 12 are symmetrically distributed around the center of the abutment plate 8. A sliding groove 13 is provided on the upper surface of the slide table 29 for the sliding connecting plates 12 to slide.

[0038] The sliding connecting plate 12 and the sliding groove 13 make it easier for the two abutting plates 8 to move closer or further apart. At the same time, the sliding connecting plate 12 and the sliding groove 13 also provide certain support for the bottom of the abutting plate 8, so that the abutting plate 8 will not tip over.

[0039] Four sets of guide components are respectively set on both sides of the two abutment plates 8. The guide components include a guide drive wheel 14, a guide motor 15 and a guide mounting plate 16. The guide drive wheel 14 is rotatably connected to the output shaft of the guide motor 15. The bottom of the guide mounting plate 16 is bolted to the guide motor 15, and one side of the guide mounting plate 16 is bolted to the abutment plate 8.

[0040] When the slide 29 needs to receive batteries from the aircraft battery compartment or needs to send power batteries into the aircraft battery compartment, the guide motor 15 starts to work. The output shaft of the guide motor 15 drives the guide drive wheel 14 to rotate. The guide drive wheel 14 abuts against one side of the power battery, which facilitates sending the power battery to the end into the aircraft or retrieving the power battery from the aircraft onto the slide 29.

[0041] Each abutment plate 8 is provided with several guide wheels 17, which are arranged along the length of the abutment plate 8.

[0042] The driven guide wheel 17 and the driving guide wheel 14 are at the same height. The driven guide wheel 17 is located inside the abutment plate 8. The driven guide wheel 17 can act as an abutment for the power battery, allowing the power battery to slide more smoothly when it needs to enter the aircraft battery compartment or enter the slide table 29 from the aircraft battery compartment.

[0043] The lifting assembly includes a rotating lifting rod 18, a lifting cylinder 19, a lifting connecting plate 20, and a lifting mounting plate 21. The rotating lifting rod 18 is located inside the vehicle body 1 at its center. The lifting connecting plate 20 is mounted on the piston rod of the lifting cylinder 19, with its top abutting against the rotating lifting rod 18. One side of the lifting mounting plate 21 is bolted to the lifting cylinder 19, and the other side is bolted to the inner wall of the vehicle body 1.

[0044] The lifting cylinder 19 generates force, and the piston rod of the lifting cylinder 19 extends or retracts, transmitting the force on the piston rod to the lifting connecting plate 20. The lifting connecting plate 20 causes the rotating lifting rod 18 to rise or fall, thereby achieving the lifting and lowering of the rotating lifting platform 2 to adapt to different heights of the aircraft battery compartment, so that the slide 29 can be aligned with the aircraft battery compartment.

[0045] The rotating assembly includes a rotating base 22, a rotating connecting plate 23, a driving pulley 24, a driven pulley 25, a synchronous belt 26, a rotary motor 27, and a rotating mounting plate 28. One side of the rotating base 22 is bolted to the inner wall of the vehicle body 1. The rotating base 22 has a rotating groove for the rotary lifting rod 18 to be inserted. The bottom of the rotating connecting plate 23 is fixedly connected to the rotary lifting rod 18, and its top is bolted to the inner wall of the rotating lifting plate. The driving pulley 24 and the driven pulley 25 are both located on the upper surface of the rotating base 22. The driven pulley 25 is rotatably connected to the rotary lifting rod 18. One end of the synchronous belt 26 is rotatably connected to the driving pulley 24, and the other end is rotatably connected to the driven pulley 25. The rotary motor 27 is rotatably connected to the driving pulley 24. The top bolt of the rotating mounting plate 28 is fixed to the rotary motor 27, and its top bolt is fixed to the rotating base 22.

[0046] The rotating base 22 provides support for other corresponding components. When the rotating lifting platform 2 is aligned with the aircraft battery compartment, the rotating motor 27 drives the drive pulley 24 to rotate. The drive pulley 24 drives the driven pulley to rotate through the synchronous belt 26, and enables the rotating lifting rod 18 to rotate. The rotating lifting rod 18 transmits power to the rotating lifting platform 2 through the rotating connecting plate 23, enabling the rotating lifting platform 2 to rotate and realize the conversion between the two slides 29. The entire device only needs to be aligned with the aircraft battery compartment once, and the power battery can be retrieved from the aircraft battery compartment to the slide 29 or sent into the aircraft battery compartment as needed.

[0047] Working principle: In use, the power battery is placed on the surface of the slide 29. Based on the width of the power battery, the abutment motor 9 drives the abutment screw 10 to bring it closer, causing the guide driven wheels 17 on the two abutment plates 8 to abut against the power battery. The lifting cylinder 19 retracts, transmitting power to the rotating lifting rod 18 via the lifting connecting plate 20. The rotating lifting rod 18, through the rotating connecting plate 23, raises the rotating lifting platform 2, aligning the empty slide 29 with the aircraft battery compartment. At this point, the relative distance between the two abutment plates 8 on the empty slide 29 is at its maximum. The guide drive wheel 14 near the end of the aircraft battery compartment begins to work, guiding the power battery and allowing it to move smoothly. Upon entering the surface of the empty slide 29, the two abutment plates 8 approach each other according to the width of the power battery, so that the guide wheels abut the power battery. The sliding cylinder 5 drives the slide 29 away from the aircraft battery compartment, and the power battery recovery is completed. At this time, the rotary motor 27 works, causing the rotary connecting rod to rotate. The rotary connecting rod causes the rotary lifting platform 2 to rotate through the rotary connecting plate 23, so that another slider 4 containing a fully charged power battery is aligned with the aircraft battery compartment. The sliding cylinder 5 drives the slide 29 to approach the aircraft battery compartment. The guide drive wheel 14 at the end near the aircraft battery compartment starts to work, so that the power battery enters the aircraft battery compartment. The slide 29 and the rotary lifting platform 2 are reset.

[0048] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
