Description

[0001] This application is a division of a Chinese invention patent with an application date of December 2, 2021, application number 202111461278.5, and name “Battery swap equipment and battery swap station containing the same”. Technical Field

[0002] The present application relates to a battery swapping device and a battery swapping station including the same. Background Art

[0003] There are two main charging methods for electric vehicles: direct charging and quick-change. Direct charging requires charging piles to charge electric vehicles, but the charging time is long and the efficiency is low. Battery swapping requires battery swapping stations to replace batteries in electric vehicles to achieve quick battery swapping, which shortens the time compared to direct charging.

[0004] The battery swapping equipment is an important piece of equipment in a battery swapping station. It is responsible for the main work of battery swapping for vehicles, including removing the battery pack from the battery swapping vehicle and installing the battery pack on the battery swapping vehicle. For the battery swapping under the vehicle, the battery swapping equipment needs to enter the bottom of the vehicle to remove the battery pack, then load out the removed battery pack, and then enter the bottom of the vehicle again with the new battery pack and install the new battery pack.

[0005] For replaceable battery packs, they can be installed to the vehicle bracket through fasteners, and the locking device on the vehicle bracket can fix the battery pack. A disassembly and assembly mechanism is usually provided on the tray to complete related operations. The disassembly and assembly mechanism can lock or unlock the fasteners to achieve the installation or removal of the battery pack. During the installation or removal of the battery pack, the vehicle and the battery swapping equipment need to be leveled and aligned. Traditional battery swapping equipment requires manual inspection and adjustment to complete the leveling and alignment with the vehicle. It is inefficient and requires manual operation, which makes it difficult to remove or install the battery pack. Summary of the invention

[0101] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0102] The embodiment of the present invention discloses a battery swap station, which includes a battery swap device. A vehicle that needs to replace a battery pack enters the battery swap station, and the battery swap device removes the battery pack with low power in the vehicle, and installs the fully charged battery pack on the vehicle, thereby completing the battery swap operation on the vehicle.

[0103] like Figure 1-Figure 7As shown, the battery exchange equipment includes a shuttle 1, a battery tray 2, a leveling component 3 and a disassembly and assembly mechanism 4. The battery tray 2 is arranged above the shuttle 1, the bottom of the leveling component 3 is connected to the shuttle 1, and the top of the leveling component 3 is used to cooperate with the chassis of the vehicle. The disassembly and assembly mechanism 4 is connected to the battery tray 2 and is used to unlock or lock the fixed parts of the battery pack.

[0104] When the battery exchange equipment is working, the shuttle 1 is located under the chassis of the vehicle. At this time, the vehicle is lifted by the lift to a position where the top of the leveling component 3 is close to the chassis of the vehicle; then, after fine-tuning, the top of the leveling component 3 and the chassis of the vehicle are in contact with each other; then, the disassembly and assembly mechanism 4 will be used to unlock or lock the fixed parts of the battery pack, so as to achieve the removal or installation of the battery pack on the vehicle. The battery tray 2 on the shuttle 1 cooperates with the chassis of the vehicle through the top of the leveling component 3. Before unlocking or locking, the disassembly and assembly mechanism 4 on the battery tray 2 is leveled and aligned, so that the battery exchange equipment reaches the leveled position, with strong adaptability, high battery exchange stability, fast working speed and high efficiency.

[0105] The number of leveling components 3 can be multiple, and the multiple leveling components 3 are respectively located at the edges of the shuttle 1. The multiple leveling components 3 are arranged at the edges of the shuttle 1, and the tops of the multiple leveling components 3 are matched with the chassis of the vehicle, which ensures that the leveling between the shuttle 1 and the vehicle is more stable and the leveling effect is better.

[0106] The top of the leveling component 3 has a support surface 31, and the multiple support surfaces 31 are located on the same plane. The multiple leveling components 3 have the same height, and the plane formed by the top surface of the leveling component 3 is the support surface 31. By having multiple support surfaces 31 located on the same horizontal plane, the leveling is more stable and the leveling effect is better.

[0107] The plane where the abutment surfaces 31 of the multiple leveling components 3 are located is parallel to the plane where the battery tray 2 is located. This ensures that the plane where the vehicle chassis / battery fixing components are located is parallel to the battery tray, so that the disassembly and assembly mechanism 4 on the battery tray 2 can accurately cooperate with the fixing components to avoid alignment deviation or jamming during unlocking or locking, thereby improving the accuracy and efficiency of battery replacement.

[0108] Specifically, there are four leveling components 3, which are respectively located at the four corners of the shuttle 1. By arranging the four leveling components 3 at the four corners of the shuttle 1, the structure is simple and stable; at the same time, the space formed between the four leveling components 3 will be used to arrange structures such as the battery tray 2 and the disassembly and assembly mechanism 4, and the leveling components 3 are arranged at the corners to avoid the position on the shuttle 1 for accommodating the battery pack, effectively avoiding interference.

[0109] The shuttle 1 also includes a lifting mechanism 11, and the battery tray 2 is arranged on the lifting mechanism 11. The lifting mechanism 11 drives the battery tray 2 to rise or fall along the disassembly direction of the battery pack. After the top of the leveling component 3 is matched with the chassis of the vehicle, the battery tray 2 is lifted to the working position by the lifting mechanism 11, so that the disassembly mechanism 4 can be aligned with the fixed parts of the battery pack, thereby unlocking or locking the battery pack. After unlocking or locking is completed, the battery tray 2 is moved downward by the lifting mechanism 11, so that the disassembly mechanism 4 moves away from the vehicle, which facilitates the shuttle 1 to drive out from under the vehicle.

[0110] In this embodiment, the battery swapping device has an initial state and a battery swapping state. When in the initial state, the leveling component 3 is higher than the disassembly and assembly mechanism 4. At the beginning of the battery swapping process, the vehicle is first leveled using the higher leveling component 3, after which the disassembly and assembly mechanism 4 performs the battery swapping operation. In other embodiments of the present invention, a lifting mechanism 11 or the like may be used so that the positional relationship between the leveling component 3 and the disassembly and assembly mechanism 4 can be adjusted at any time to facilitate the battery swapping operation.

[0111] The lifting mechanism 11 includes a first driving unit 111 and a transmission unit 112. The first driving unit 111 is arranged on the shuttle 1, and the transmission unit 112 is connected to the first driving unit 111 and the battery tray 2 respectively. The first driving unit 111 will be used to provide driving force, and the transmission unit 112 will exert force on the battery tray 2, so that the battery tray 2 can rise or fall along the direction of battery pack disassembly and assembly. The first driving unit 111 and the transmission unit 112 are used to realize the lifting and lowering of the battery tray 2. While ensuring its lifting stability, the structure is simplified as much as possible to ensure that it does not affect the battery replacement operation of the battery replacement equipment.

[0112] In this embodiment, the first driving part 111 is a motor, and the transmission part 112 is a cam. The motor drives the cam to rotate, and when the protruding part of the cam lifts the battery tray 2, the battery tray 2 is located at the working height. The structure is simple, the installation is very convenient, and the cost is low. Of course, in other optional embodiments, the first driving part 111 can also use other driving mechanisms such as hydraulic devices to provide driving force, and the transmission part 112 can also use other transmission components such as transmission rods to achieve the transmission of the force.

[0113] The battery tray 2 is connected to the shuttle 1 via the tray installation mechanism 5 along the battery pack disassembly and assembly direction, and the battery tray 2 can elastically move parallel to and / or perpendicular to the battery disassembly and assembly direction relative to the shuttle 1. The tray installation mechanism 5 enables the shuttle 1 and the battery tray 2 to elastically move parallel to and / or perpendicular to the battery disassembly and assembly direction, so that the battery tray 2 is floatingly connected to the shuttle 1, so that the battery tray 2 can drive the disassembly and assembly mechanism 4 to fine-tune its position in the battery pack disassembly and assembly direction within a certain floating space, thereby improving the adaptability of the tray installation mechanism 5, the battery tray 2 and the disassembly and assembly mechanism 4, facilitating the disassembly and assembly mechanism 4 to align the fixed parts of the battery pack, achieving high stability in battery replacement, and high working speed and efficiency. In addition, the floating in the battery pack disassembly and assembly direction can prevent the battery tray 2 from rising excessively, resulting in a rigid collision between the protruding parts on the battery tray 2 and the vehicle, reducing component damage and extending the service life of the battery replacement equipment.

[0114] The tray mounting mechanism 5 includes a fixing portion 51, a mounting portion 52 and a tray elastic component 53. The mounting portion 52 is connected to the battery tray 2, the fixing portion 51 is connected to the shuttle 1, and the tray elastic component 53 is arranged between the mounting portion 52 and the fixing portion 51. The tray elastic component 53 is elastically deformed in parallel and / or perpendicular to the battery disassembly and assembly direction, so that the mounting portion 52 can be elastically moved relative to the fixing portion 51 in parallel and / or perpendicular to the battery disassembly and assembly direction. The tray elastic component 53 is arranged between the mounting portion 52 and the fixing portion 51, and the mounting portion 52 can be elastically moved relative to the fixing portion 51 in parallel and / or perpendicular to the battery disassembly and assembly direction by relying on the elastic deformation of the tray elastic component 53 itself, so that the mounting portion 52 can drive the battery tray 2 to fine-tune the position in the battery pack disassembly and assembly direction within a certain floating space. The tray mounting mechanism 5 has a simple overall structure and is very convenient to use.

[0115] In this embodiment, the fixing portion 51 includes a shell 511 and a fixing base 512, the fixing base 512 is arranged below the mounting portion 52 along the battery pack disassembly and assembly direction, the shell 511 is arranged around the outside of the mounting portion 52, the shell 511 is arranged above the fixing base 512 and connected to the fixing base 512; the tray elastic component 53 includes a first elastic component 531 and / or a second elastic component 532, the first elastic component 531 is arranged between the mounting portion 52 and the fixing base 512, and the first elastic component 531 can be elastically deformed in a direction parallel to the battery disassembly and assembly direction; the second elastic component 532 is arranged between the mounting portion 52 and the shell 511, and the second elastic component 532 can be elastically deformed in a direction perpendicular to the battery disassembly and assembly direction.

[0116] The first elastic component 531 is disposed between the mounting portion 52 and the fixed base 512. The first elastic component 531 is retracted relative to the fixed base 512 to drive the mounting portion 52 to float in a direction parallel to the battery pack disassembly and assembly direction. The second elastic component 532 is disposed between the mounting portion 52 and the housing 511. The second elastic component 532 is retracted relative to the housing 511 to drive the mounting portion 52 to float in a direction perpendicular to the battery pack disassembly and assembly direction.

[0117] In this embodiment, the first elastic component 531 and the second elastic component 532 can both adopt springs, which have a simple and reliable structure and low cost. In other optional implementations, the first elastic component 531 and the second elastic component 532 can also adopt other elastic components such as rubber parts.

[0118] The shell 511 and the mounting portion 52 are nested in each other. On the one hand, the mounting portion 52 can transfer the floating along the direction perpendicular to the battery pack disassembly and assembly direction to the shell 511, so that only the mounting portion 52 needs to be connected to the battery tray 2 to achieve floating in parallel with the battery pack disassembly and assembly direction and floating in the direction perpendicular to the battery pack disassembly and assembly direction at the same time, thereby reducing the components connected to the mounting portion 52 and simplifying the overall structure. On the other hand, the shell 511 is arranged on the outside of the mounting portion 52, which can prevent the mounting portion 52 from being skewed during the floating process and maintain the stability of the battery tray 2 during the floating process.

[0119] In this embodiment, the fixing portion 51 is sleeved on the outside of the mounting portion 52, and there is more space between the shell 511 and the mounting portion 52 to set the second elastic component 532. The second elastic component 532 can be arranged along the entire circumference, which is beneficial to increase the floating direction on the plane perpendicular to the battery pack disassembly and assembly direction, and further improve the adaptability of the tray mounting mechanism 5 and the battery tray 2.

[0120] There are multiple tray installation mechanisms 5, and the multiple tray installation mechanisms 5 are evenly distributed at the bottom of the battery tray 2. The multiple tray installation mechanisms 5 ensure that the battery tray 2 floats more smoothly, and avoids the battery tray 2 from tilting during the floating process to affect the installation alignment process, thereby achieving high stability of battery replacement, fast working speed and high efficiency. Specifically, the number of tray installation mechanisms 5 is at least four, and at least four tray installation mechanisms 5 are evenly distributed at the bottom of the battery tray 2.

[0121] In one embodiment, one end of the disassembly and assembly mechanism 4 facing the fixed component can be elastically moved relative to the battery tray 2 in a direction parallel to the battery disassembly and assembly direction. The end of the disassembly and assembly mechanism 4 will be able to move in the vertical direction relative to the battery tray 2. Even if there is an error in the relative positioning of the disassembly and assembly mechanism 4 and the fixed component in the vertical direction, the disassembly and assembly mechanism 4 can be fine-tuned within a certain floating space in the vertical direction and can be connected to the fixed component, thereby achieving unlocking or locking of the fixed component, reducing the positioning accuracy requirements and improving the alignment efficiency. At the same time, the movement of the disassembly and assembly mechanism 4 allows the disassembly and assembly mechanism 4 to float in the direction of battery pack disassembly and assembly, which can prevent the disassembly and assembly mechanism 4 from rising excessively and causing a rigid collision with the vehicle, thereby reducing component damage and extending the service life of the battery exchange equipment.

[0122] The disassembly and assembly mechanism 4 includes a mounting seat 41, a connecting portion 42 and a disassembly and assembly portion 43. The lower end of the mounting seat 41 is mounted on the battery tray 2. The disassembly and assembly portion 43 is used to unlock or lock the fixed parts of the battery pack. The disassembly and assembly portion 43 is connected to the mounting seat 41 through the connecting portion 42. A third elastic component 44 is provided between the connecting portion 42 and the mounting seat 41. The third elastic component 44 undergoes elastic deformation in a direction parallel to the battery disassembly and assembly direction so that the disassembly and assembly portion 43 can elastically move relative to the battery tray 2 in a direction parallel to the battery disassembly and assembly direction. The disassembly and assembly part 43 is connected to the mounting seat 41 through the connection part 42. The axes of the connection part 42 and the mounting seat 41 coincide with each other, and the connection part 42 can move on the mounting seat 41 in a direction parallel to the battery disassembly and assembly direction. The third elastic component 44 acts on the connection part 42 and the mounting seat 41 respectively and is used to drive the connection part 42 to move in a direction away from the mounting seat 41, so that the disassembly and assembly part 43 can move elastically relative to the battery tray 2 in a direction parallel to the battery disassembly and assembly direction, and can be reset through the third elastic component 44 after the disassembly and assembly part 43 is used, and has high stability. Among them, part of the structure of the connection part 42 is arranged in the mounting seat 41, and the installation of the connection part 42 and the disassembly and assembly part 43 is realized through the mounting seat 41, providing a reliable protection structure for the connection part 42 and the disassembly and assembly part 43, increasing the structural stability, and the overall structure is simple and compact.

[0123] One end of the disassembly mechanism 4 facing the fixed component can swing relative to the battery tray 2 in a direction oblique to the battery disassembly direction. The lower end of the disassembly portion 43 is movably connected to the upper end of the connecting portion 42, and the upper end of the disassembly portion 43 can swing from the axis of the connecting portion 42 to the outside of the axis of the connecting portion 42, so that the disassembly portion 43 can swing relative to the battery tray 2 in a direction oblique to the battery disassembly direction. Even if there is an error in the relative positioning of the disassembly mechanism 4 and the fixed component in the horizontal direction, the disassembly mechanism 4 can be fine-tuned within a certain floating space through the swing and can be connected to the fixed component, thereby achieving unlocking or locking of the fixed component, reducing the positioning accuracy requirements and improving the efficiency of aligning the fixed component.

[0124] In this embodiment, the disassembly part 43 is connected to the connecting part 42 via a pivot shaft. The swing between the disassembly part 43 and the connecting part 42 is realized by the pivot shaft, and the structure is simple and reliable. Of course, other movable connection methods can also be used between the disassembly part 43 and the connecting part 42, which are not limited here.

[0125] The disassembly mechanism 4 further includes a reset component 45, which is sleeved on the outer circumference of the disassembly portion 43 and the connecting portion 42, and is used to make the axis of the disassembly portion 43 coincide with the axis of the connecting portion 42. The reset component 45 is sleeved on the outer circumference of the disassembly portion 43 and drives the disassembly portion 43 to reset, so that the axis of the disassembly portion 43 can coincide with the axis of the fixing component, thereby achieving unlocking or locking of the fixing component, and having higher stability.

[0126] In this embodiment, the reset component 45 is a spring, specifically a wave spring. In other embodiments, the reset component 45 can also be other elastic materials such as a rubber sleeve, which has a simple structure and is reliable in use.

[0127] The disassembly mechanism 4 further includes a second driving part 46, which is in transmission connection with the connecting part 42, and applies torque to the disassembly part 43 through the connecting part 42. The second driving part 46 is used to provide a rotational driving force, and applies torque to the disassembly part 43 through the transmission of the connecting part 42, so that the fixing part can be twisted to achieve unlocking or locking, which is very convenient to use, easy to control, high precision and high stability.

[0128] In this embodiment, the disassembly mechanism 4 is a torque gun, the disassembly part 43 is a sleeve device, and the second driving part 46 is a motor assembly; the motor assembly drives the sleeve device to rotate through the connecting part 42. The fixed component is unlocked or locked by controlling the rotation of the sleeve device of the torque gun. The torque gun is driven by the motor assembly, has a simple and stable structure, and can achieve precise control of the torque and the number of rotations.

[0129] The disassembly and assembly mechanism 4 may also include a harmonic reducer assembly, the power output end of the motor assembly is connected to the power input end of the harmonic reducer assembly, and the power output end of the harmonic reducer assembly is used to output power to drive the connection part 42 to rotate. By using the motor assembly and the harmonic reducer assembly, the length of the disassembly and assembly mechanism 4 can be effectively reduced, so that it is convenient to set the disassembly and assembly mechanism 4 in the power exchange equipment of the power exchange station. The output of the motor assembly is high speed and low torque. The power of the motor assembly can be converted into low speed and high torque through the harmonic reducer to better meet the working requirements of the sleeve device of the torque gun.

[0130] There are multiple disassembly and assembly mechanisms 4, which are distributed in an array on the battery tray 2, and the positions of the multiple disassembly and assembly mechanisms 4 correspond to the multiple fixed components on the battery pack. By arranging disassembly and assembly mechanisms 4 corresponding to the multiple fixed components on the battery pack on the battery tray 2, all disassembly and assembly mechanisms 4 can simultaneously unlock or lock all fixed components to achieve disassembly or installation between the battery pack and the vehicle, which greatly improves the efficiency and stability of unlocking or locking.

[0131] The battery tray 2 is also provided with a positioning component 21, which cooperates with the positioning hole set on the chassis of the vehicle. The height of the positioning component 21 extending from the top surface of the battery tray 2 is greater than the height of the disassembly mechanism 4 extending from the top surface of the battery tray 2. After the leveling component 3 is leveled, the lifting mechanism 11 will be used to drive the battery tray 2 to rise along the disassembly direction of the battery pack. Since the height of the positioning component 21 is greater than the height of the disassembly part 43, the positioning component 21 will be inserted into the positioning hole to achieve positioning before the disassembly part 43 contacts the fixed part. By setting the relative position of the positioning component 21 and the disassembly part 43 to correspond to the relative position of the positioning hole and the fixed part, the disassembly part 43 is aligned with the fixed part of the battery pack when the positioning component 21 is inserted into the positioning hole, so as to facilitate the disassembly part 43 to unlock and lock the fixed part. By using the positioning component 21 and the positioning hole that cooperate with each other, the precise positioning between the vehicle and the battery tray 2 is achieved, so that the position accuracy requirements between the two are reduced during the unlocking and locking process, the success rate of unlocking is greatly improved, and the battery replacement has high stability, fast working speed and high efficiency.

[0132] The top of the positioning component 21 has a guide surface with a gradually increasing diameter from top to bottom. The top of the positioning component 21 can be specifically conical or truncated cone-shaped, and the formed guide surface has a guiding function. The guide surface at the top of the positioning component 21 makes it easier to insert the positioning component 21 into the positioning hole, and the battery tray 2 can be straightened even with a slight error in the horizontal direction, so as to achieve accurate alignment between the disassembly and assembly portion 43 and the fixed component of the battery pack.

[0133] There are multiple positioning components 21, and the multiple positioning components 21 are respectively located on both sides of the center of the battery tray 2. By arranging multiple positioning components 21 on both sides of the center of the battery tray 2, it is ensured that the battery tray 2 does not move horizontally within the plane where it is located, thereby further improving the stability of unlocking. In this embodiment, there are two positioning components 21, and the two positioning components 21 are respectively located on both sides of the center of the battery tray 2.

[0134] The battery tray 2 is provided with a support component 22 for supporting the battery pack, and the height of the support component 22 extending from the upper surface of the battery tray 2 is lower than the height of the disassembly and assembly mechanism 4 extending from the upper surface of the battery tray 2. By providing the support component 22 on the battery tray 2, the support component 22 is used to support the battery pack, so that the battery pack falls on the support component 22 after unlocking or before locking, instead of falling directly on the disassembly and assembly mechanism 4, which effectively avoids damage caused by the impact of the battery pack on the disassembly and assembly mechanism 4, and greatly improves the safety and stability of the battery swapping equipment.

[0135] In this embodiment, there are multiple support components 22, and multiple support components 22 are arranged on the outer edges and / or the middle area of ​​the battery tray 2. The multiple support components 22 effectively support the outer edges and / or the middle area of ​​the battery pack, which can effectively prevent the battery pack from flipping on the battery tray 2 and improve the stability of the battery tray 2 when carrying the vehicle battery pack. The support components 22 are preferably made of nylon, which can ensure the support strength and prevent the support components 22 from causing collision damage to the battery pack.

[0136] The battery swap station also includes a control system, which is connected to the battery swap equipment by wired or wireless communication, and is used to control the disassembly and assembly mechanism 4. The control system is electrically connected to the battery swap equipment and is used to control the battery swap equipment. The control system can specifically control the movement of the shuttle 1 to enter and exit the bottom of the electric vehicle, and can also raise or lower the lifting mechanism 11, as well as control the unlocking or locking operation of the disassembly and assembly mechanism 4, thereby realizing the disassembly or installation of the battery pack, which is very convenient, efficient, and safe.

[0137] The disassembly and assembly mechanism 4 is a torque gun, and the control system is used to control the rotation switch, output power, and receive the number of rotations and torque information of the torque gun. The control system can detect whether each step of the torque gun is successful in the entire process of unlocking or locking by controlling the rotation switch, output power, and receiving the number of rotations and torque information of the torque gun, thereby achieving precise control with high safety and stability.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
