Description

Technical Field

[0001] This utility model relates to a battery swapping system for vertical take-off and landing aircraft, belonging to the field of aircraft battery swapping technology. Background Technology

[0002] Electric vertical take-off and landing (eVTOL) aircraft are aircraft that are driven by electric motors and have the ability to take off and land vertically without a runway. With their advantages of being green, low-carbon, safe and efficient, eVTOL aircraft have become the core carrier of future urban air traffic and short-distance transportation, and are widely used in high-frequency short-distance flights such as urban commuting, emergency medical rescue and material transportation.

[0003] However, the development of related battery energy storage and charging technologies has become the main factor restricting the development of the vertical take-off and landing aircraft industry. The typical escort range of a purely electric vertical take-off and landing aircraft is 100-300 kilometers, and the charging time using superchargers is about 30-60 minutes. Vertical take-off and landing aircraft also have the problems of short battery range and long charging time. Battery range and charging efficiency directly affect the operational economy of vertical take-off and landing aircraft. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a battery swapping system for vertical takeoff and landing aircraft.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A battery swapping system for a vertical take-off and landing aircraft includes a battery swapping platform, a battery swapping trolley, and a battery compartment. The vertical take-off and landing aircraft can start and stop on the battery swapping platform. A battery is provided at the bottom of the vertical take-off and landing aircraft, and a side battery swapping port is provided on the side of the bottom of the vertical take-off and landing aircraft. The battery compartment is used for storing and charging the battery.

[0006] The battery swapping trolley includes a vehicle body, a lifting assembly mounted on the vehicle body, and a battery platform for carrying batteries. The bottom of the vehicle body is equipped with wheels, and the battery platform is mounted on the vehicle body via the lifting assembly. The height of the battery platform is adjustable under the action of the lifting assembly. The battery swapping trolley is used to transport the depleted batteries of the vertical take-off and landing aircraft to the empty compartment of the battery bay, and to transfer the fully charged batteries of the battery bay to the vertical take-off and landing aircraft.

[0007] The beneficial effects of this utility model are: the aircraft can start and stop on the battery swapping platform; when the aircraft battery is low on power, it can directly perform side battery swapping. The side battery swapping port can be located on the rear, left, or right side of the aircraft. The battery swapping trolley is pushed to the side battery swapping port of the aircraft, and the position of the battery swapping trolley is adjusted, including its front, back, left, and right positions, and the height of the battery platform is adjusted by the lifting component so that the battery platform can correspond to the position of the side battery swapping port. The depleted battery of the aircraft is pulled out and placed on the battery platform, and then the battery swapping trolley is pushed to transport the depleted battery to the battery compartment. The position of the battery swapping trolley is adjusted so that the battery platform can be aligned with the empty compartment. The depleted battery is inserted into the battery compartment, and then the position of the battery swapping trolley is adjusted so that the battery platform corresponds to the fully charged battery compartment. The fully charged battery is pulled out from the battery compartment and placed on the battery platform, and transported to the corresponding position of the side battery swapping port of the aircraft. The fully charged battery is then sent into the aircraft, and the battery swapping of the aircraft is completed. If there are multiple batteries, the above process is repeated until all batteries are replaced. This invention features a simple structure and convenient operation. The battery swapping process takes less than 10 minutes, and the short battery swapping time, achieved by using a side-switch method, enables rapid energy replenishment for the aircraft. This solves the problems of low endurance and charging efficiency in vertical take-off and landing aircraft, and facilitates the widespread application of vertical take-off and landing aircraft.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the battery platform is provided with a sliding seat, the sliding seat is provided with a traction electromagnet, and the battery is provided with a ferromagnetic structure that can be attracted to the traction electromagnet.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when the vertical takeoff and landing aircraft needs to have its battery swapped, the lifting component of the battery swapping trolley is activated, raising the battery platform to the same height as the battery of the vertical takeoff and landing aircraft. The sliding seat is pushed, and the sliding seat moves closer to the battery. The ferromagnetic structure of the battery can attract the traction electromagnet on the sliding seat. Pulling the sliding seat can remove the battery from the vertical takeoff and landing aircraft. The lifting component is activated to lower the height of the battery platform to ensure the stability of the battery swapping trolley during movement. Then the battery swapping trolley is moved to the battery compartment, and the battery platform is raised to the height of an empty compartment in the battery compartment. The traction electromagnet is energized and demagnetized, and the battery can then be pushed into the empty compartment for charging.

[0011] Furthermore, a sliding guide mechanism is provided between the battery platform and the sliding seat. The sliding guide mechanism includes a slide rail disposed on the battery platform and a slider adapted to the slide rail. The slider is disposed at the bottom of the sliding seat.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the slide rail can guide and limit the sliding of the sliding seat on the battery platform, so that the battery can enter and exit the battery platform along the slide rail direction, avoid its deviation, and ensure the stability of the battery entering and exiting the battery platform.

[0013] Furthermore, the battery platform is also provided with a plurality of platform rollers, which are used to assist the battery in entering and exiting the battery platform.

[0014] The beneficial effect of adopting the above-mentioned further solution is that multiple stage ball bearings can assist the battery in and out of the battery stage, reduce the friction between the battery and the battery stage, and make the battery entry and exit smoother, less labor-intensive, and more efficient.

[0015] Furthermore, the lifting assembly includes a lifting platform and a lifting drive mechanism for driving the lifting platform to move up and down. The lifting platform is mounted on the vehicle body via the lifting drive mechanism. An adjustment mechanism is provided between the battery carrier and the lifting platform. The adjustment mechanism is used to adjust the alignment of the battery carrier with the battery to be transferred.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the lifting drive mechanism can adjust the height of the lifting platform, thereby realizing the height adjustment of the battery carrier, enabling the battery carrier to lift and lower to meet the needs of the vertical take-off and landing aircraft for battery retrieval and battery compartment retrieval. Considering that the bottom plane of the battery to be replaced inside the vertical take-off and landing aircraft may not correspond to the bearing plane of the battery carrier, which would affect the battery entering the battery carrier, an adjustment mechanism is set up. The bearing plane of the battery carrier can be adjusted by the adjustment mechanism to make its bearing plane correspond to the bottom plane of the battery before the battery is retrieved, thus avoiding damage to the battery.

[0017] Furthermore, the adjustment mechanism includes a first adjustment cylinder and a second adjustment cylinder, the cylinder bodies of the first adjustment cylinder and the second adjustment cylinder are respectively disposed on the lifting platform, and the piston rods of the first adjustment cylinder and the second adjustment cylinder are respectively connected to the battery carrier.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the adjusting cylinder can be a hydraulic cylinder, and the position of the adjusting cylinder can be installed according to the needs of the battery platform. For example, the first adjusting cylinder can be set on one side of the bottom of the battery platform, and the second adjusting cylinder can be set in the middle of the bottom of the battery platform or on the other side of the bottom, as long as it can meet the adjustment of the bearing plane of the battery platform.

[0019] Furthermore, the lifting platform is also provided with a support hinge seat, which is disposed on the lifting platform and has a ball head. The bottom of the battery carrier is provided with a connecting seat, which has a ball socket that is adapted to the ball head.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the support hinge seat and the connecting seat can not only meet the support requirements of the battery platform, but also facilitate the adjustment of the battery platform when removing the battery, so that the bearing plane of the battery platform can be parallel to the bottom surface of the battery, avoiding the impact of unevenness between the bearing plane of the battery platform and the bottom surface of the battery on the removal of the battery.

[0021] Furthermore, a battery cover is also provided on the vertical take-off and landing aircraft corresponding to the side power exchange port.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the battery cover at the side battery swapping port can protect the aircraft's battery, while when a battery swapping is needed, the battery cover can be opened to facilitate the removal and replacement of the battery.

[0023] Furthermore, the bottom of the vertical take-off and landing aircraft is provided with a battery positioning frame for accommodating the battery. The battery inlet and outlet of the battery positioning frame is the side battery swapping port. The battery cover is disposed on the battery positioning frame or on the fuselage of the vertical take-off and landing aircraft.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the battery positioning frame can position the battery at the bottom of the aircraft, which can not only meet the battery power supply requirements of the vertical take-off and landing aircraft and make it easier for the battery to enter and exit the aircraft, but also meet the battery side swapping requirements of the vertical take-off and landing aircraft.

[0025] Furthermore, the battery compartment is provided with multiple slots for accommodating the batteries, and each slot is provided with a tray for supporting the batteries, and the tray is provided with multiple support balls.

[0026] The beneficial effects of adopting the above-mentioned further solution are that multiple compartments can store multiple batteries, meeting the needs of battery storage and charging. The battery compartment can not only charge batteries, but also store them for use in battery swapping for vertical take-off and landing aircraft. In order to facilitate the entry and exit of batteries, multiple bearing rollers are also set on the battery support plate, which reduces friction and makes it easier and faster to enter and exit batteries.

Detailed Implementation

[0036] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0037] like Figures 1-8 As shown, a battery swapping system for a vertical takeoff and landing (VTOL) aircraft 4 includes a battery swapping platform 1, a battery swapping trolley 2, and a battery compartment 3. The VTOL aircraft 4 can start and stop on the battery swapping platform 1. A battery 5 is provided at the bottom of the VTOL aircraft 4, and a side battery swapping port 403 is provided on the side of the bottom of the VTOL aircraft 4. The battery compartment 3 is used for storing and charging the battery 5. The side battery swapping port 403 can be located on the rear, left, or right side of the bottom of the VTOL aircraft 4.

[0038] The battery swapping trolley 2 includes a vehicle body 201, a lifting assembly mounted on the vehicle body 201, and a battery platform 202 for carrying the battery 5. The bottom of the vehicle body 201 is equipped with wheels. The battery platform 202 is mounted on the vehicle body 201 via the lifting assembly. The height of the battery platform 202 is adjustable under the action of the lifting assembly. The battery swapping trolley 2 is used to transport the depleted battery 5 of the vertical take-off and landing aircraft 4, i.e., the battery with insufficient power, to the empty compartment 301 of the battery compartment 3, and to transfer the fully charged battery 5 of the battery compartment 3 into the vertical take-off and landing aircraft 4.

[0039] The battery platform 202 is equipped with a sliding seat 205, and the sliding seat 205 is equipped with a traction electromagnet 206. The battery 5 is equipped with a ferromagnetic structure that can attract the traction electromagnet 206. When the vertical takeoff and landing aircraft 4 needs to be charged, the lifting component of the battery swapping cart 2 is activated, and the battery platform 202 is raised to the same height as the battery 5 of the vertical takeoff and landing aircraft 4. The sliding seat 205 is pushed and moves closer to the battery 5. The ferromagnetic structure of the battery 5 can attract the traction electromagnet 206 on the sliding seat 205. Pulling the sliding seat 205 can remove the battery 5 from the vertical takeoff and landing aircraft 4. The lifting component is activated to lower the height of the battery platform 202 to ensure the stability of the battery swapping cart 2 during movement. Then the battery swapping cart 2 is moved to the battery compartment 3, and the battery platform 202 is raised to the height of an empty compartment 301 on the battery compartment 3. The traction electromagnet 206 is energized and demagnetized, and the battery 5 can be pushed into the empty compartment 301 for charging.

[0040] A sliding guide mechanism is also provided between the battery platform 202 and the sliding seat 205. The sliding guide mechanism includes a slide rail 207 disposed on the battery platform 202 and a slider adapted to the slide rail 207. The slider is disposed at the bottom of the sliding seat 205. The slide rail 207 can guide and limit the sliding of the sliding seat 205 on the battery platform 202, so that the battery 5 can enter and exit the battery platform 202 along the direction of the slide rail 207, avoiding its deviation and ensuring the stability of the battery 5 entering and exiting the battery platform 202.

[0041] The battery platform 202 is also equipped with a plurality of platform balls 208, which are used to assist the battery 5 in entering and exiting the battery platform 202. The plurality of platform balls 208 can assist the battery 5 in entering and exiting the battery platform 202, reduce the friction between the battery 5 and the battery platform 202, and make the entry and exit of the battery 5 smoother, less strenuous and more efficient.

[0042] The lifting assembly includes a lifting platform 204 and a lifting drive mechanism 203 for driving the lifting platform 204 to move up and down. The lifting platform 204 is mounted on the vehicle body 201 via the lifting drive mechanism 203. An adjustment mechanism is provided between the battery carrier 202 and the lifting platform 204. The adjustment mechanism is used to adjust the alignment of the battery carrier 202 with the battery 5 to be transferred. The lifting drive mechanism 203 can adjust the height of the lifting platform 204, thereby adjusting the height of the battery carrier 202. This allows the battery carrier 202 to move up and down to meet the needs of the vertical take-off and landing aircraft 4 for loading and unloading batteries 5 and the battery compartment 301 for loading and unloading batteries 5. Considering that the bottom plane of the battery 5 to be replaced inside the vertical take-off and landing aircraft 4 may not correspond to the bearing plane of the battery carrier 202, which would affect the battery 5 from entering the battery carrier 202, an adjustment mechanism is provided. The bearing plane of the battery carrier 202 can be adjusted by the adjustment mechanism to make its bearing plane correspond to the bottom plane of the battery 5 before the battery 5 is picked up, so as to avoid damaging the battery 5.

[0043] The lifting drive mechanism 203 adopts a scissor lifting mechanism.

[0044] The adjustment mechanism includes a first adjusting cylinder 209 and a second adjusting cylinder 210. The cylinder bodies of the first adjusting cylinder 209 and the second adjusting cylinder 210 are respectively mounted on the lifting platform 204, and the piston rods of the first adjusting cylinder 209 and the second adjusting cylinder 210 are respectively connected to the battery carrier 202. The adjusting cylinders can be hydraulic cylinders. The position of the adjusting cylinders can be installed according to the requirements of the battery carrier 202. For example, the first adjusting cylinder 209 can be located on one side of the bottom of the battery carrier 202, and the second adjusting cylinder 210 can be located in the middle of the bottom of the battery carrier 202 or on the other side of the bottom, as long as it can meet the adjustment requirements of the bearing plane of the battery carrier 202.

[0045] The lifting platform 204 is also equipped with a supporting hinge seat 211. The supporting hinge seat 211 is disposed on the lifting platform 204 and has a ball head. The bottom of the battery carrier 202 is equipped with a connecting seat 212, which has a ball socket that matches the ball head. The cooperation between the supporting hinge seat 211 and the connecting seat 212 not only meets the support requirements of the battery carrier 202, but also facilitates the adjustment of the battery carrier 202 when removing the battery 5, so that the bearing plane of the battery carrier 202 can be parallel to the bottom surface of the battery 5, avoiding the problem of unevenness between the bearing plane of the battery carrier 202 and the bottom surface of the battery 5 affecting the removal of the battery 5. To ensure the support stability of the battery carrier, multiple adjusting cylinders and supporting hinge seats can be used.

[0046] A battery cover 401 is also provided on the vertical take-off and landing aircraft 4 corresponding to the side battery swapping port 403. The battery cover 401 at the side battery swapping port 403 can protect the battery 5 of the aircraft 4, and when it is necessary to swap the battery, the battery cover 401 can be opened to facilitate the removal and replacement of the battery 5.

[0047] The bottom of the vertical takeoff and landing (VTOL) aircraft 4 is also provided with a battery positioning frame 402 for accommodating the battery 5. The battery 5 inlet and outlet of the battery positioning frame 402 is the side battery swapping port 403. The battery cover 401 is disposed on the battery positioning frame 402 or on the fuselage of the VTOL aircraft 4. The battery positioning frame 402 can position the battery 5 at the bottom of the aircraft 4, which can not only meet the power supply requirements of the battery 5 of the VTOL aircraft 4 and make it easier for the battery 5 to enter and exit the aircraft 4, but also meet the side battery swapping requirements of the VTOL aircraft 4.

[0048] The battery positioning frame 402 is equipped with a fixing electromagnet for stably positioning the battery 5. The inner end of the battery 5 is provided with a ferromagnetic structure that attracts the fixing electromagnet. After the battery 5 is installed in place on the battery positioning frame 402 of the aircraft 4, it can be stably positioned by attracting the fixing electromagnet to the ferromagnetic structure on the battery 5. When it is necessary to remove the battery 5, the fixing electromagnet can be energized and demagnetized, allowing the battery 5 to detach from the battery positioning frame 402 and be pulled out to meet the battery swapping needs of the aircraft 4.

[0049] The ferromagnetic structure can be a steel plate, iron plate, or similar structure.

[0050] The battery compartment 3 has multiple slots 301 for accommodating the batteries 5. Each slot 301 is equipped with a tray 302 for supporting the battery 5, and the tray 302 is equipped with multiple support rollers 303. The multiple slots 301 can store multiple batteries 5, meeting the needs of battery storage and charging. The battery compartment 3 can not only charge batteries, but also store batteries 5 for use by the vertical take-off and landing aircraft 4 for battery swapping. In order to facilitate the entry and exit of the batteries 5 from the slots 301, multiple support rollers 303 are also provided on the trays 302 supporting the batteries 5. The friction is small, making it easier and faster to enter and exit the batteries 5.

[0051] Battery swapping platform 1 serves as the docking location for aircraft 4. When vertical takeoff and landing aircraft 4 needs a battery swap, it will dock on battery swapping platform 1. After the aircraft comes to a complete stop, the battery swapping personnel will open the battery cover 401 on aircraft 4, energize and demagnetize the fixing electromagnet, unlock the battery 5, and push the battery swapping trolley 2 closer to the battery 5 inlet / outlet of the battery positioning frame 402. The battery swapping trolley 2 can be adjusted manually in terms of forward / backward and left / right positions, and its vertical position can be adjusted using the scissor lift mechanism. If the battery platform 202 of the battery swapping trolley 2 is not level with the bottom plane of the battery 5 on aircraft 4, the adjusting rod under the battery platform 202 can be adjusted to make the battery platform 202 parallel to the bottom surface of the battery 5. After the battery swapping trolley 2 has been adjusted in all directions, the depleted battery 5 on aircraft 4 can be easily pulled out using a sliding mechanism. The traction magnet on seat 205 attracts the ferromagnetic structure on the depleted battery 5, pushing the sliding seat 205 to place the depleted battery 5 on the battery platform 202. Then, the battery swapping staff pushes the battery swapping trolley 2 to move the depleted battery 5 to the vicinity of the battery compartment 3. By adjusting the height and position of the battery swapping trolley 2, the depleted battery 5 is inserted into the empty slot 301 of the battery compartment 3. After adjusting the position of the battery swapping trolley 2, the fully charged battery 5 in the battery compartment 3 is pulled out and sent back to the vicinity of the battery positioning frame 402 on the aircraft 4. The position of the battery swapping trolley 2 is adjusted again, and then the sliding seat 205 is pushed to insert the fully charged battery 5 into the battery positioning frame 402 on the aircraft 4. The traction electromagnet 206 is energized and demagnetized, and the fully charged battery 5 is detached from the sliding seat 205. The battery swapping process is completed for one battery. If there are multiple batteries 5, the above process is repeated until all batteries 5 are replaced. Then simply close the battery cover 401 of the battery positioning frame 402. The entire battery swapping process is convenient, and the swapping time can even be shortened to 3-5 minutes, greatly improving the battery swapping efficiency of the aircraft 4 and making the vertical take-off and landing aircraft 4 more suitable for high-frequency short-distance flight operations.
