Description

[0001] This application claims priority to Chinese patent application No. 202410380046.4, filed on March 29, 2024. This application incorporates the entirety of the aforementioned patent application. Technical Field

[0002] The present application relates to the technical field of battery replacement for electric vehicles, and in particular to a battery replacement device and a battery replacement station. Background Art

[0003] With the development and popularization of new energy vehicles, battery pack quick-swap technology has also developed rapidly. For large vehicles, such as heavy trucks and light trucks, the heavy weight of the body and cargo leads to higher battery pack capacity requirements, requiring a sufficiently large capacity of electricity to support the operation of large vehicles.

[0004] In traditional battery swapping, large new energy vehicles use a top-lift method to secure large battery containers to the vehicle's beams. These containers are located close to the cab, posing significant safety risks to both the driver and the vehicle during operation and during top-lift battery swapping. Furthermore, battery failures can directly harm the driver. Furthermore, the top-lift method places high demands on the site for battery swap stations, requiring sufficient space for lifting equipment to transport and store batteries, resulting in high construction costs.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable and easy-to-popularize battery swap mode. For example, a chassis-type battery swap mode for passenger cars is adopted. In the chassis-type battery swap mode, it is necessary to control the battery swap equipment to move as a whole to the battery swap position under the battery swap vehicle, and then perform lifting operations and remove or install battery pack operations to complete the entire battery swap process. In this battery swap process, due to the limited space under the body of the battery swap vehicle, especially heavy-duty battery swap vehicles that are difficult to drive and park on platforms above the ground, the space under the body of the battery swap vehicle is even more limited. If a battery swap device is used for battery swapping, the battery swap device needs to carry the depleted battery or the fully charged battery back and forth and in and out of the bottom of the battery swap vehicle during the battery swap process. In order to meet the power requirements of heavy-duty battery swap vehicles, the battery packs are very large, which leads to a great restriction on the available space for the battery swap equipment. At this time, if you want to increase the available space for the battery swapping equipment, you can only move the battery swapping equipment in the space sunken from the ground. Due to the multiple driving of heavy-duty battery swapping vehicles before and after battery swapping, the ground structure under this method will inevitably become unreliable and difficult to bear the multiple loads of the battery swapping vehicles, reducing the life of the equipment structure and posing a safety hazard to the battery swapping vehicles.

[0006] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Summary of the Invention

[0007] The present application provides a battery swapping device and a battery swapping station. The battery swapping device realizes battery disassembly and assembly operations on the battery swapping vehicle through the telescopic movement of the telescopic mechanism and the lifting and lowering movement of the battery swapping body. The telescopic mechanism and the battery swapping body have the functions of battery disassembly, installation and battery transportation, which can ensure the rapid and safe replacement of battery packs, improve the battery swapping efficiency, avoid the battery swapping equipment as a whole entering under the chassis of the battery swapping vehicle and occupying the bottom space of the vehicle, and solve at least one technical problem existing in the background technology.

[0008] The technical solutions adopted in this application are:

[0009] A battery-exchanging device comprises a fixed support frame, a battery-exchanging body arranged between the support frames and capable of being raised and lowered, and a battery-exchanging device arranged in the battery-exchanging body and capable of being telescopically moved to the outside of the support frame. The battery-exchanging device can be disassembled and assembled on a battery-exchanging vehicle through the telescopic movement and the lifting and lowering movement of the battery-exchanging body. The battery-exchanging device comprises a telescopic mechanism and a battery-exchanging mechanism arranged on the top surface of the telescopic mechanism. The telescopic mechanism drives the battery-exchanging mechanism to extend into the bottom of the battery-exchanging vehicle to replace the battery pack.

[0010] In this technical solution, the battery swap body can be raised and lowered on the support frame to adjust the height of the battery swap device. When it is necessary to remove a depleted battery from the battery swap vehicle or install a fully charged battery on the battery swap vehicle, the battery swap device is adjusted to a height position corresponding to the chassis of the battery swap vehicle by raising and lowering the battery swap body relative to the support frame, and then the battery swap device is extended, thereby realizing battery disassembly and assembly operations on the battery swap vehicle. The present application arranges the battery-swapping device in the battery-swapping body, which is the base of the battery-swapping device. The battery-swapping device extends from the battery-swapping body through a telescopic mechanism, and simultaneously drives the battery-swapping mechanism to extend from the battery-swapping body. Therefore, when actually taking and placing the battery pack, it is only necessary to extend the telescopic mechanism from the battery-swapping body so that the battery-swapping mechanism enters under the chassis of the battery-swapping vehicle to remove and install the battery pack, thereby avoiding the entire battery-swapping equipment from entering under the chassis of the battery-swapping vehicle and occupying the bottom space of the vehicle. Even if the battery-swapping vehicle is changing batteries on a battery-swapping platform flush with the ground, the bottom of the vehicle body can provide more operating space for the removal or installation of the battery pack, making the battery-swapping operation simpler and faster, and avoiding the shortened life and safety hazards caused by digging a pit under the battery-swapping platform to create a sunken ground space. The battery swap mechanism is used to support the battery pack and to lock and unlock the battery pack at the bottom of the battery swap vehicle, and to transfer the battery pack in and out of the battery swap vehicle. For example, the battery pack can interact between the battery swap vehicle and the battery storage rack of the battery swap station. When installing a fully charged battery, the battery swap mechanism carrying the fully charged battery enters under the body of the battery swap vehicle from the side through the horizontal extension movement of the telescopic mechanism, and then locks the fully charged battery on the battery swap vehicle. Then, the battery swap mechanism is withdrawn from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism, ready for the next battery swap, and avoids the battery swap vehicle so that the battery swap vehicle can leave the battery swap platform. When removing a depleted battery, the battery swap mechanism enters under the body of the battery swap vehicle from the side through the horizontal extension movement of the telescopic mechanism, unlocks and supports the depleted battery locked in the battery swap vehicle, and then is withdrawn from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism.

[0011] Preferably, the telescopic mechanism includes a plurality of telescopic forks that are arranged at intervals and telescopically move synchronously; the battery exchange mechanism includes a bracket provided on the top surfaces of the plurality of telescopic forks, a battery carrying part that can move along the telescopic direction of the telescopic mechanism and provided on the bracket, and a plurality of unlocking pins for locking and unlocking the battery pack. After the battery exchange mechanism is extended into the bottom of the battery exchange vehicle through the telescopic movement of the telescopic forks, the unlocking pins and the battery carrying part unlock or lock the battery pack as the battery exchange body moves up and down and the battery carrying part moves along the telescopic direction.

[0012] In this technical solution, the telescopic mechanism can be telescoped over a long distance by means of a telescopic fork, which improves the adaptability to battery swapping positions at different distances and battery swapping for different models. Multiple telescopic forks can form a stable support for the bracket and the battery carrying part located on the bracket. After the telescopic fork brings the battery swap mechanism under the battery swap vehicle, the unlocking pin and the battery carrying part unlock or lock the battery pack as the battery swap body moves up and down and the battery carrying part moves along the telescopic direction. Therefore, the battery swap mechanism can automatically unlock or lock the battery pack under the battery swap vehicle. The telescopic mechanism can only be used to enter and exit the bottom of the battery swap vehicle. The unlocking of the battery pack depends on the lifting and lowering of the battery swap body and the movement of the unlocking pin and the battery carrying part, which optimizes the source of power. When the battery pack is unlocked, the telescopic mechanism is in a stationary state. Only the battery carrying part and the unlocking pin need to move and lift to unlock. The unlocking process is more stable and more accurate.

[0013] Preferably, the number of the telescopic forks is two, and the bracket includes two cross beams whose ends are connected to the top surface of the telescopic fork by hanging ears, two longitudinal beams connected between the two cross beams by side walls close to the end surfaces, and a support plate arranged in the area between the cross beams and the longitudinal beams, and the two ends of the support plate along the telescopic direction respectively have hanging parts for hanging with the two cross beams, and the battery carrying part is movably arranged in the middle area of ​​the support plate through a first driving mechanism.

[0014] In this technical solution, the two telescopic forks, while ensuring that they can provide stable support for the bracket, form a space between them to accommodate the bracket, so that the bracket can be set between the two telescopic forks and stably mounted on the telescopic forks on both sides. The bracket is set as a frame structure composed of two crossbeams and two longitudinal beams. The structure is simple and convenient for the installation of the pallet. On the basis of ensuring structural strength and load-bearing capacity, it helps to reduce the lightweight of the bracket and reduce the overall weight, thereby helping to reduce the load on the telescopic forks. Moreover, the space between the crossbeams and the longitudinal beams avoids the sinking of the pallet, so that the pallet is mounted on the two crossbeams based on the hanging parts at both ends. The middle area can sink as much as possible and use the space under the bracket, which helps to reduce the height of the battery-carrying part located in the middle area of ​​the pallet, and improves the adaptability to battery-swap vehicles with chassis of different heights.

[0015] Preferably, the first driving mechanism includes a first driving motor, a screw transmission-connected to the output shaft of the first driving motor, and a nut transmission-connected to the screw, the battery carrying part includes a transmission plate fixed to the nut, and a battery tray floatable on the transmission plate through an elastic member; and / or, the battery exchange mechanism also includes a guide mechanism provided between the support plate and the transmission plate, the guide mechanism including a guide rail provided on the support plate and a slider provided on the transmission plate.

[0016] In this technical solution, a battery tray located above the transmission plate supports the battery pack. The transmission plate serves as an intermediate structure for the first drive mechanism to drive the battery tray, enabling simultaneous movement of the battery tray and the transmission plate. The battery tray is floatable on the transmission plate via elastic members, allowing it to adapt to the shape and condition of different battery-swap vehicle chassis, maintaining a close fit with the vehicle's bottom. This ensures stable support for the battery pack and further enhances stability and safety during the battery swap process. Furthermore, when a battery pack released from a battery-swap vehicle falls onto the battery tray, the elastic members cushion its fall, effectively protecting it from damage caused by vibration or impact. The transmission mechanism, screw, and nut drive the transmission plate, leveraging the reliability of the screw-nut kinematic pair to enhance the stability and precision of the first drive mechanism's movement of the transmission plate, optimizing the battery pack's loading and unloading process and ensuring smooth loading and unloading. The guide mechanism provides guidance for the reciprocating movement of the transmission plate in the extension and retraction directions, ensuring a stable and smooth movement process, reducing jams, avoiding deflection in other directions, and ensuring smooth locking and unlocking of the battery pack.

[0017] Preferably, the middle area of ​​the support plate is recessed inwardly, the first drive motor is arranged on a hanging portion on the crossbeam located on the inner side along the telescopic direction, the first drive mechanism also includes a gear mechanism that is transmission-connected between the output shaft of the first drive motor and the lead screw, the gear mechanism includes a driving gear and a driven gear that are meshed with each other in the vertical direction, the driving gear is transmission-connected to the output shaft of the first drive motor, and the driven gear is transmission-connected to the lead screw.

[0018] In this technical solution, the middle area of ​​the support plate is recessed inward to form a sinking cavity that sinks into the middle of the bracket. The battery carrying part is located in the sinking cavity. The side walls of the sinking cavity protect the battery carrying part. Moreover, the battery carrying part being located in the sinking cavity also helps to reduce the height of the battery tray, thereby improving the adaptability to battery-swap vehicles with chassis of different heights. The first drive motor is arranged on the hanging part on the inner side of the support plate. The first drive motor is located on the side of the battery tray close to the battery-swap body. The battery-swap mechanism only needs to extend the battery tray under the battery-swap vehicle to swap the battery. The first drive motor does not need to extend under the vehicle. It runs on the outside of the vehicle body without interfering with the body of the battery-swap vehicle, thereby avoiding occupying the space under the vehicle body. The first drive mechanism only needs to extend the lead screw and nut under the transmission plate to realize transmission. The lead screw and nut occupy a small height space, which helps to reduce the height of the transmission plate and the battery tray located on the transmission plate. The first drive motor is located on the hanging part, and the transmission plate is located in the sunken cavity in the middle of the support plate. There is a large height difference between the two, which is not suitable for direct transmission connection. Therefore, by setting a gear mechanism between the first drive motor and the transmission plate, the first drive motor and the transmission plate are indirectly connected through transmission, and the reliability of the gear mechanism transmission can be improved to improve the stability and accuracy of the first drive mechanism in the process of driving the transmission plate to move.

[0019] Preferably, the number of the first driving mechanisms is two, which are arranged at intervals in the middle area of ​​the support plate, the number of the transmission plates is two and are arranged one-to-one corresponding to the first driving mechanisms to carry the battery tray; and / or the transmission plate is in a "J" shape, the lead screw is arranged corresponding to the middle arched area of ​​the "J" shape, the outer edges of the "J" shape are respectively connected to the support plate through the guide mechanism, and the upper surface of the outer edge of the "J" shape is respectively used to set a plurality of elastic members for realizing the floating of the battery tray and / or a plurality of U-shaped slots that cooperate with the card plate on the battery tray to drive the battery tray to move synchronously.

[0020] In the technical solution, the two first driving mechanisms synchronously drive the two transmission plates to move on both sides of the supporting plate, the two transmission plates support the battery tray together, the supporting surface is large, the support stability of the battery pack is high, the battery tray is more balanced in stress, and the movement stroke of the battery tray driven by the two first driving mechanisms is more stable and reliable. The two first driving mechanisms are arranged on both sides of the supporting plate, fully utilize the installation space on the supporting plate, balance the stress of the supporting plate, and improve the structural stability. The transmission plate is in the shape of a Chinese character, compared with the flat plate structure, the strength of the Chinese character-shaped structure is higher, the anti-deformation ability is stronger, the middle arching area of the Chinese character provides a transmission space for the supporting plate below the transmission plate, the lead screw utilizes the area for transmission, which helps to realize compact structure, the outer edges of the Chinese character-shaped structure are connected with the supporting plate through the guide mechanism respectively, and the elastic members for supporting the battery tray are also arranged on the outer edges of the Chinese character-shaped structure, so that the area below the contact area between the transmission plate and the elastic member is carried by the guide mechanism instead of being in a suspended state. Therefore, when the battery pack is subjected to gravity, the gravity of the battery pack is transmitted to the supporting plate through the elastic member, the transmission plate and the guide mechanism, so as to provide stable support for the battery pack and reduce the risk of deformation of the transmission plate.

[0021] Preferably, the battery replacing mechanism further comprises a second driving mechanism arranged between the two first driving mechanisms along the telescopic direction, for driving the supporting plate to move along a direction perpendicular to the telescopic direction, so as to adjust the position of the battery tray until it matches the position of the battery pack.

[0022] In the technical solution, the second driving mechanism is used to drive the supporting plate to move along a direction perpendicular to the telescopic direction, so as to drive the battery tray on the supporting plate to move along a direction perpendicular to the telescopic direction. The direction perpendicular to the telescopic direction is parallel to the body of the battery replacing vehicle. When the driver deviates from the experience and visual method of parking the battery replacing vehicle in front of or behind the battery replacing position, the position of the supporting plate can be adjusted along the direction parallel to the body of the battery replacing vehicle by the second driving mechanism. Since the supporting plate drives the battery carrying part to move synchronously, the battery tray can automatically and more quickly find the battery pack on the battery replacing vehicle, so as to adjust the position of the battery tray until it matches the position of the battery pack. Instead of the method of adjusting the position of the body of the battery replacing vehicle multiple times to find the battery replacing position in the prior art, the position of the battery tray in the direction parallel to the body of the battery replacing vehicle is easier to adjust, the structure is simple, which helps to reduce the difficulty of battery replacing, save the cost of the battery replacing station, and improve the efficiency of battery replacing.

[0023] Preferably, the second drive mechanism includes a second drive motor arranged above the hanging portion and located between the two first drive motors, a synchronization shaft passing through the support plate along the telescopic direction and connected to the support plate, two driven wheels respectively fixed to both ends of the synchronization shaft, and a driving wheel meshed with one of the driven wheels and transmission-connected to the output shaft of the second drive motor, and racks meshed with the driven wheels are respectively provided on the two cross beams to drive the support plate to move relative to the bracket.

[0024] In this technical solution, the second drive mechanism includes a second drive motor and a rack-and-pinion mechanism consisting of a driving wheel, a driven wheel, and a rack. The reliability of the rack-and-pinion mechanism transmission can be used to improve the stability and accuracy of the second drive mechanism in the process of moving the pallet. The rack is installed on the crossbeam. When the second drive motor is running, the rotation of the driving wheel drives the driving wheel to move along the rack, thereby driving the second drive motor to move. Since the second drive motor is arranged on the hanging part of the pallet, the second drive motor drives the pallet to move synchronously. Compared with the method of setting a gear between the second drive motor and the rack to achieve transmission, the second drive motor realizes transmission through the driving wheel, the driven wheel and the rack, which helps to appropriately reduce the size of the rack-and-pinion mechanism and reduce the installation space it occupies, which is conducive to the compact, miniaturized and flat structure of the battery exchange mechanism. The two driven wheels are connected by a synchronous shaft, and the synchronous shaft is connected to the support plate. When the second drive motor drives the driving wheel on one side to rotate, the driven wheels on both sides are driven by the driven wheel meshing with the driving wheel and the synchronous shaft. The driven wheels on both sides are meshed and move along the corresponding racks at both ends of the power exchange mechanism, thereby driving the support plate to move together through the synchronous shaft. The force on the support plate is more balanced, and the moving stroke is more stable and reliable.

[0025] Preferably, the two racks are respectively arranged on the inner side walls of the crossbeam, and the two hanging parts are respectively provided with through holes for avoiding the driven wheel and the driving wheel; and / or, the middle area of ​​the support plate is provided with two reinforcing plates along the telescopic direction, and the two reinforcing plates extend to the hanging parts connected to the two ends to form an accommodating space for accommodating the synchronization shaft.

[0026] In this technical solution, the rack is set on the inner wall of the crossbeam, utilizing the inner space of the crossbeam, which contributes to a compact structure. At the same time, it also facilitates the sinking of the driven wheel meshing with the rack relative to the crossbeam, thereby sinking the synchronous shaft, so that the synchronous shaft can be connected to the support plate designed to sink relative to the bracket. Moreover, this design effectively widens the distance between the second drive motor and the rack, thereby providing space for the installation of the driving wheel and the driven wheel. The middle area of ​​the support plate is provided with two reinforcing plates along the telescopic direction. The reinforcing plates strengthen the structure of the support plate, improve its strength, and have a higher ability to bear high loads, reducing the risk of deformation when dealing with heavy battery packs.

[0027] Preferably, the battery replacing mechanism further comprises a lifting driving mechanism connected to the bottom surface of the battery tray, for driving the plurality of unlocking pins to move up and down relative to the battery tray to perform locking and unlocking operations on the battery pack.

[0028] In the technical solution, the unlocking pins can be lifted relative to the battery tray, so that the adaptability of the unlocking pins to the locking mechanism of the battery pack of different models, sizes and installation positions on the battery replacing vehicle can be improved by adjusting the height of the unlocking pins. For example, when the position of the locking mechanism of the battery pack is high, the position of the unlocking pins can be raised, and when the position of the locking mechanism of the battery pack is low, the position of the unlocking pins can be lowered. The unlocking pins can be lifted by the lifting driving mechanism to perform locking and unlocking on the battery pack, so that the lifting action of the unlocking pins required in the process of locking and unlocking the battery pack on the battery replacing vehicle can be achieved not only by lifting the whole battery replacing body, but also by the lifting driving mechanism. Compared with the locking and unlocking of the battery pack by lifting the whole battery replacing body and the unlocking pins, the locking and unlocking of the battery pack by lifting the unlocking pins through the lifting driving mechanism is independent of the lifting of the battery replacing body. During the locking and unlocking process, the telescopic fork and the battery carrying part are in a relatively static state, and the fewer components that move up and down, the higher the accuracy of the lifting of the unlocking pins, the higher the reliability of the locking and unlocking, and the higher the safety and efficiency of the battery replacing process. In addition, the flexibility of the battery replacing equipment is improved, and the battery replacing process is more efficient and safe.

[0029] Preferably, in the vertical direction along the telescopic direction, a plurality of unlocking pins are arranged at each end of the battery tray, and the plurality of unlocking pins at the same end of the battery tray are driven to move up and down synchronously by the same lifting driving mechanism.

[0030] In the technical solution, the plurality of unlocking pins can match the technology of arranging a plurality of locking mechanisms of the battery pack on the battery replacing vehicle to achieve the synchronous action of the plurality of locking mechanisms of the battery pack to perform locking and unlocking. In addition, the unlocking pins at both ends of the battery tray can correspond to different levels of locking and unlocking, respectively. For example, the unlocking pins at one end correspond to a first level of locking and unlocking, and the unlocking pins at the other end correspond to a second level of locking and unlocking. The first level of locking and unlocking and the second level of locking and unlocking can be completed synchronously. The two unlocking pins at the same end of the battery tray are driven to move up and down synchronously by the lifting driving mechanism, which simplifies the driving structure and improves the synchronicity of the locking and unlocking.

[0031] Preferably, the plurality of unlocking pins at the same end of the battery tray are arranged at intervals along the telescopic direction. The lifting driving mechanism comprises an electric push rod, a connecting rod and a transmission rod corresponding to the plurality of unlocking pins. The connecting rod is connected to the electric push rod, and the two ends of the transmission rod are hinged to the connecting rod and the unlocking pins, respectively. The electric push rod drives the connecting rod to move along the telescopic direction and drives the unlocking pins to move up and down through the transmission of the transmission rod.

[0032] In this technical solution, when the electric push rod drives the connecting rod to translate, the connecting rod drives all the transmission rods to rotate relative to the connecting rod, so that the transmission rod drives the unlocking pin to move up and down, making the lifting and lowering movement of the unlocking pin stable and reliable, thereby improving the unlocking efficiency.

[0033] Preferably, a mounting frame corresponding to the locking and unlocking drive mechanism is provided at the bottom of the battery tray, the electric push rod is installed on the mounting frame and drives the connecting rod to translate along the telescopic direction within the mounting frame, and the mounting frame is provided with a first guide structure for guiding the translation of the connecting rod and a second guide structure for guiding the lifting and lowering movement of the unlocking pin.

[0034] In this technical solution, the mounting frame is installed at the bottom of the battery tray, serving as the supporting structure for the lift drive mechanism. This improves the portability of the lift drive mechanism assembly and allows the lift drive mechanism to rise and fall with the battery tray. A first guide structure guides the connecting rod for stable and smooth translation, while a second guide structure guides the release pin for stable and smooth movement.

[0035] Preferably, a plurality of battery positioning pins are provided in the middle area of ​​the battery tray for cooperating with the positioning holes at the bottom of the battery pack to drive the battery pack to move synchronously; and / or a plurality of body positioning pins are provided on the hanging portion at the outer end of the support plate along the telescopic direction for cooperating with the positioning holes on the battery swap vehicle to maintain the position of the locking mechanism on the battery swap vehicle during the movement of the battery pack.

[0036] In this technical solution, the positioning pins provided on the battery tray and the support plate can ensure the correct position of the battery pack during the battery replacement process, preventing the battery pack from shifting during transportation and the unlocking process, thereby improving the accuracy and safety of battery replacement. In addition, the battery positioning pins cooperate with the battery pack to produce a positioning and clamping effect on the battery pack, so that the battery tray can drive the battery pack to move synchronously, and the battery pack can be more resistant to unlocking force, improving the stability of battery unlocking.

[0037] The present application provides a battery swap station, comprising a battery swap platform for battery swap vehicles to park and swap batteries, and also comprising the battery swap equipment as described above, wherein the battery swap equipment is arranged on at least one side of the battery swap platform.

[0038] In this technical solution, since the battery swap station adopts the above-mentioned battery swap equipment, it can ensure the rapid and safe replacement of battery packs, improve the battery swap efficiency, and avoid the battery swap equipment as a whole entering the bottom of the battery swap vehicle and the battery compartment, thereby occupying the space under the vehicle and the space inside the battery compartment, thereby optimizing the entire battery swap process.

[0039] Due to the adoption of the above-mentioned technical solution, the technical effect achieved by this application is that the battery-exchange body can be raised and lowered on the support frame to adjust the height of the battery-exchange device. When it is necessary to remove a depleted battery from the battery-exchange vehicle or install a fully charged battery on the battery-exchange vehicle, the battery-exchange device is adjusted to a height position corresponding to the chassis of the battery-exchange vehicle by raising and lowering the battery-exchange body relative to the support frame, and then the battery-exchange device is extended, thereby realizing battery disassembly and assembly operations on the battery-exchange vehicle. The present application arranges the battery-swapping device in the battery-swapping body, which is the base of the battery-swapping device. The battery-swapping device extends from the battery-swapping body through a telescopic mechanism, and simultaneously drives the battery-swapping mechanism to extend from the battery-swapping body. Therefore, when actually taking and placing the battery pack, it is only necessary to extend the telescopic mechanism from the battery-swapping body so that the battery-swapping mechanism enters under the chassis of the battery-swapping vehicle to remove and install the battery pack, thereby avoiding the entire battery-swapping equipment from entering under the chassis of the battery-swapping vehicle and occupying the bottom space of the vehicle. Even if the battery-swapping vehicle is changing batteries on a battery-swapping platform flush with the ground, the bottom of the vehicle body can provide more operating space for the removal or installation of the battery pack, making the battery-swapping operation simpler and faster, and avoiding the shortened life and safety hazards caused by digging a pit under the battery-swapping platform to create a sunken ground space. The battery swap mechanism is used to support the battery pack and to lock and unlock the battery pack at the bottom of the battery swap vehicle, and to transfer the battery pack in and out of the battery swap vehicle. For example, the battery pack can interact between the battery swap vehicle and the battery storage rack of the battery swap station. When installing a fully charged battery, the battery swap mechanism carrying the fully charged battery enters under the body of the battery swap vehicle from the side through the horizontal extension movement of the telescopic mechanism, and then locks the fully charged battery on the battery swap vehicle. Then, the battery swap mechanism is withdrawn from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism, ready for the next battery swap, and avoids the battery swap vehicle so that the battery swap vehicle can leave the battery swap platform. When removing a depleted battery, the battery swap mechanism enters under the body of the battery swap vehicle from the side through the horizontal extension movement of the telescopic mechanism, unlocks and supports the depleted battery locked in the battery swap vehicle, and then is withdrawn from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism.

[0061] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0063] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components.

[0064] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. In the description of the specification, the description of the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0065] In the embodiments of the present application, a battery replacement device and a battery replacement station are provided. For the convenience of description and understanding, the following content provided by the present application is described on the basis of the structure of the product. Of course, those skilled in the art can understand that the above structure is only a specific example and illustrative description, and cannot constitute a specific limitation on the technical solutions provided by the present application.

[0066] As shown in Figures 1 to 15 , the battery replacement device 100 provided by the present application comprises a fixed support frame 1, a battery replacement main body 2 arranged between the support frames 1 and movable up and down, and a battery replacement device arranged in the battery replacement main body 2 and movable in and out of the support frame 1. The battery replacement device is used for battery disassembly and assembly operation of the battery replacement vehicle through the telescopic movement of the battery replacement device and the up and down movement of the battery replacement main body 2. The battery replacement device comprises a telescopic mechanism 3 and a battery replacement mechanism 4 arranged on the top surface of the telescopic mechanism 3. The battery replacement mechanism 4 is driven by the telescopic mechanism 3 to extend into the bottom of the battery replacement vehicle to replace the battery pack.

[0067] In the technical solution, the support frame 1 is the overall outer frame of the battery replacement device 100, supporting all components of the battery replacement device 100. The battery replacement main body 2 is movable up and down on the support frame 1 to adjust the height of the battery replacement device. In order to reduce the overall weight of the battery replacement device 100, the battery replacement main body 2 can be a frame structure. In addition, as shown in Figure 1 , the support frame 1 can be composed of a plurality of columns. As a preferred embodiment, the support frame 1 can also be expanded outward along the circumferential side of the battery replacement device 100 to form a battery rack with a battery compartment. An electrical connector is installed in the battery compartment to charge the battery pack locked in the battery compartment. In the preferred embodiment, as shown in Figure 1 and Figure 2As shown, the battery exchange body 2 can be connected to the support frame 1 through the lifting and moving component 5, and the battery exchange body 2 can be rotatably connected to the lifting and moving component 5. By rotating the battery exchange body 2, the direction of the battery exchange device can be adjusted to facilitate telescopic movement to perform battery disassembly and assembly operations and / or battery transportation operations. Specifically, the lifting and moving component 5 can also use a frame structure with rollers 51, which not only helps to reduce weight, but also can achieve lifting and movement by rolling along the support frame 1 through the rollers 51. The battery exchange body 2 and the lifting and moving component 5 can be rotationally connected through motor drive and gear transmission.

[0068] When it is necessary to remove a depleted battery from a battery-swapping vehicle or install a fully charged battery on the battery-swapping vehicle, the battery-swapping device is adjusted to a height position corresponding to the chassis of the battery-swapping vehicle by lifting and lowering the battery-swapping body 2 relative to the support frame 1, and then the battery-swapping device is extended, thereby realizing the battery disassembly and assembly operation of the battery-swapping vehicle. The present application arranges the battery-exchanging device in the battery-exchanging body 2, which is the base of the battery-exchanging device. The battery-exchanging device extends from the battery-exchanging body 2 through the telescopic mechanism 3, and simultaneously drives the battery-exchanging mechanism 4 to extend from the battery-exchanging body 2. Therefore, when actually taking and placing the battery pack, it is only necessary to extend the telescopic mechanism 3 from the battery-exchanging body 2 so that the battery-exchanging mechanism 4 enters under the chassis of the battery-exchanging vehicle to remove and install the battery pack, thereby avoiding the battery-exchanging equipment 100 as a whole entering under the chassis of the battery-exchanging vehicle and occupying the bottom space of the vehicle. Even if the battery-exchanging vehicle is exchanging batteries on a battery-exchanging platform flush with the ground, the bottom of the vehicle body can provide more operating space for the disassembly or installation of the battery pack, making the battery-exchanging operation simpler and faster, and avoiding the reduction in life and safety hazards caused by digging pits under the battery-exchanging platform to create a sunken space on the ground.

[0069] The battery swap mechanism 4 is used to support the battery pack and to lock and unlock the battery pack at the bottom of the battery swap vehicle, and to transfer the battery pack in and out of the battery swap vehicle. For example, the battery pack can interact between the battery swap vehicle and the battery compartment 11 as described above. When installing a fully charged battery, the battery swap mechanism 4 carrying the fully charged battery enters the bottom of the battery swap vehicle from the side of the battery swap vehicle through the horizontal extension movement of the telescopic mechanism 3, and then locks the fully charged battery on the battery swap vehicle. Then, the battery swap mechanism 4 is withdrawn from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism 3, ready for the next battery swap, and avoids the battery swap vehicle so that the battery swap vehicle can leave the battery swap platform; when removing a low-charged battery, the battery swap mechanism 4 enters the bottom of the battery swap vehicle from the side of the battery swap vehicle through the horizontal extension movement of the telescopic mechanism 3, unlocks and supports the low-charged battery locked in the battery swap vehicle, and then withdraws from under the body of the battery swap vehicle through the horizontal retraction movement of the telescopic mechanism 3.

[0070] As a preferred embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the telescopic mechanism 3 includes a plurality of telescopic forks 31 that are spaced apart and move telescopically in sync; the battery-exchanging mechanism 4 includes a bracket 41 provided on the top surface of the plurality of telescopic forks 31, a battery-carrying portion 42 that can move along the telescopic direction of the telescopic mechanism 3 and provided on the bracket 41, and a plurality of unlocking pins 43 for locking and unlocking the battery pack. After the battery-exchanging mechanism 4 extends into the bottom of the battery-exchanging vehicle through the telescopic movement of the telescopic forks 31, the unlocking pins 43 and the battery-carrying portion 42 unlock or lock the battery pack along with the lifting and lowering movement of the battery-exchanging body 2 and the movement of the battery-carrying portion 42 along the telescopic direction. In this technical solution, the telescopic mechanism 3 can achieve telescopic extension over a longer distance through the telescopic forks 31, thereby improving the adaptability to battery-exchanging positions at different distances and for battery-exchanging vehicles of different types. The plurality of telescopic forks 31 can form a stable support for the bracket 41 and the battery-carrying portion 42 located on the bracket 41. After the telescopic fork 31 brings the battery swap mechanism 4 to the bottom of the battery swap vehicle, the unlocking pin 43 and the battery carrying part 42 unlock or lock the battery pack as the battery swap body 2 rises and falls and the battery carrying part 42 moves along the telescopic direction. Therefore, the battery swap mechanism 4 can automatically unlock or lock the battery pack under the battery swap vehicle. The telescopic mechanism 3 can only be used to enter and exit under the battery swap vehicle. The locking and unlocking of the battery pack depends on the lifting and lowering of the battery swap body 2 and the movement of the unlocking pin 43 and the battery carrying part 42, which optimizes the source of power. When the battery pack is locked and unlocked, the telescopic mechanism 3 is in a stationary state. Only the battery carrying part 42 and the unlocking pin 43 need to move and rise to lock and unlock. The locking and unlocking process is more stable and more accurate. For example, the liftable unlocking pin 43 can be adapted to the battery locking mechanism of the following battery-swap vehicle: the battery locking mechanism includes multiple lock bases with lock slots, lock tongues movably arranged inside, and lock links connecting multiple lock tongues, the lock tongues are used to open or close the lock slots, and when the battery pack is locked, since the lock shaft on the battery pack needs to enter the lock slot, the unlocking pin 43 can be raised to push the lock link, so that the lock link drives all the lock tongues to move upward to open the lock slot, so that the lock shaft can enter the lock slot, and then the unlocking pin 43 is lowered to cancel When the lock link is pushed up, the lock link drives the lock tongue to move downward and reclose the lock slot. At this time, the lock tongue blocks the lock shaft from disengaging from the lock slot, thereby locking the battery pack. When the battery pack is unlocked, since the lock shaft on the battery pack needs to be disengaged from the lock slot, the unlocking pin 43 can be raised to push the lock link, so that the lock link drives all the lock tongues to move upward to open the lock slot, so that the lock shaft can be disengaged from the lock slot. After the lock shaft is disengaged from the lock slot, the unlocking pin 43 descends to cancel the push on the lock link, and the lock link drives the lock tongue to move downward and reclose the lock slot.

[0071] Furthermore, if Figures 3 to 8As shown, there are two telescopic forks 31, and the bracket 41 includes two crossbeams 411 connected to the top surface of the telescopic fork 31 at both ends via hooks 413, two longitudinal beams 412 connected between the two crossbeams 411 by side walls near the end surfaces, and a support plate 44 located in the area between the crossbeams 411 and the longitudinal beams 412. The support plate 44 has a hook portion 441 for hooking to the two crossbeams 411 at both ends along the telescopic direction. The battery carrier 42 is movably located in the middle area of ​​the support plate 44 via a first drive mechanism 45. In this technical solution, the two telescopic forks 31, while ensuring stable support for the bracket 41, form a space between them to accommodate the bracket 41, allowing the bracket 41 to be positioned between the two telescopic forks 31 and stably mounted on the telescopic forks 31 on both sides. Those skilled in the art will appreciate that the battery pack itself is a heavy structure, and coupled with the weight of the bracket 41, the load-bearing stability requirements for the telescopic fork 31 are extremely high. It is necessary to meet the stability requirements of the battery pack load while also reducing the load on the telescopic fork 31 as much as possible to prevent the telescopic fork 31 from bending and deforming. This makes it unsuitable for the bracket 41 to be a single, heavy solid structure. Therefore, the present technical solution configures the bracket 41 as a frame structure composed of two crossbeams 411 and two longitudinal beams 412. This simple structure facilitates the installation of the support plate 44, and while ensuring structural strength and load-bearing capacity, it helps to lightweight the bracket 41 and reduce the overall weight, thereby helping to reduce the load on the telescopic fork 31. Furthermore, the lugs 413 at both ends of the crossbeam 411 enhance the ease of installation of the bracket 41 on the telescopic mechanism 3. The lugs 413 at both ends can be directly attached and fixed to the tops of the two telescopic forks 31. Specifically, the lugs 413 can also be securely fastened to the telescopic forks 31 with bolts to improve stability. The space between the crossbeam 411 and the longitudinal beam 412 prevents the tray 44 from sinking, so that the tray 44 is mounted on the two crossbeams 411 based on the hanging parts 441 at both ends. The middle area can sink as much as possible and utilize the space below the bracket 41, which helps to reduce the height of the battery supporting part 42 located in the middle area of ​​the tray 44, thereby improving the adaptability to battery-swap vehicles with chassis of different heights.

[0072] Regarding the specific structure of the first driving mechanism 45, in a preferred embodiment, as shown in FIG. Figure 7 and Figure 10As shown, the first drive mechanism 45 includes a first drive motor 451, a leadscrew 452 drivingly connected to the output shaft of the first drive motor 451, and a nut 453 drivingly connected to the leadscrew 452. The battery carrier 42 includes a transmission plate 421 fixed to the nut 453, and a battery tray 423 floatably mounted on the transmission plate 421 via an elastic member 422. The transmission of the first drive mechanism 45, leadscrew 452, and nut 453 drives the transmission plate 421 to move. The reliability of the leadscrew-nut kinematic pair can be utilized to improve the stability and accuracy of the first drive mechanism 45 in driving the transmission plate 421, optimizing the battery pack locking and unlocking process and ensuring smooth locking and unlocking. Specifically, when the first drive motor 451 is running, it drives the lead screw 452 to rotate, causing the nut 453 to translate along the lead screw 452, and then the nut 453 drives the transmission plate 421 to move. The battery tray 423 located above the transmission plate 421 is used to support the battery pack. The transmission plate 421 serves as the intermediate structure for the first drive mechanism 45 to drive the battery tray 423 to move, so that the first drive mechanism 45 drives the transmission plate 421 to move while the transmission plate 421 drives the battery tray 423 to move synchronously. The battery tray 423 is floatable on the transmission plate 421 via the elastic member 422, allowing the battery tray 423 to float up and down. This allows the battery tray 423 to adapt to the shape and state of different battery-swapping vehicle chassis and maintain contact with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving stability and safety during the battery-swapping process. For example, when the battery-swapping vehicle chassis is horizontal, the battery tray 423 as a whole can be in a horizontal position to achieve battery swapping. When the vehicle chassis is tilted, the battery tray 423 as a whole can be in a tilted position to achieve battery swapping. When removing a low-charged battery, when the low-charged battery is transferred from the vehicle to the battery tray 423, the battery tray 423 moves downward under the action of the battery pack's gravity. Moreover, when the battery pack unlocked from the battery-swapping vehicle falls on the battery tray 423, the compression deformation of the elastic member 422 will cushion the fall of the battery pack, effectively protecting the battery pack and preventing damage to the battery pack due to vibration or collision. In a preferred embodiment, the elastic member 422 is a spring, and a plurality of springs may be arranged on the transmission plate 421 to support the battery tray 423 together, so as to improve the stability of the battery tray 423 when floating up and down.

[0073] In a preferred embodiment, Figure 10As shown, the battery exchange mechanism 4 also includes a guide mechanism 46 provided between the support plate 44 and the transmission plate 421. The guide mechanism 46 includes a guide rail 461 provided on the support plate 44 and a slider 462 provided on the transmission plate 421. The guide mechanism 46 provides a guiding effect on the reciprocating movement of the transmission plate 421 in the direction of extension and contraction, ensuring a stable and smooth movement process, reducing jams, avoiding deflection in other directions, and ensuring smooth locking and unlocking of the battery pack. In order to ensure the stability of the movement of the transmission plate 421, a set of guide mechanisms 46 can be used on both sides of the transmission plate 421 to slide in connection with the support plate 44.

[0074] Furthermore, if Figure 3 、 Figure 7 、 Figure 9 and Figure 10As shown, the middle region of the support plate 44 is inwardly recessed, the first driving motor 451 is arranged on the hanging part 441 of the cross beam 411 on the inner side in the telescopic direction, and the first driving mechanism 45 further comprises a gear mechanism in transmission connection between the output shaft of the first driving motor 451 and the lead screw 452. The gear mechanism comprises a driving gear 454 and a driven gear 455 meshing with each other in the vertical direction. The driving gear 454 is in transmission connection with the output shaft of the first driving motor 451, and the driven gear 455 is in transmission connection with the lead screw 452. In the technical solution, the middle region of the support plate 44 is inwardly recessed to form a sunken cavity sunken in the middle of the bracket 41, and the battery carrying part 42 is located in the sunken cavity. The side wall of the sunken cavity protects the battery carrying part 42, and the location of the battery tray 423 is also lowered to improve the adaptability of the battery replacement vehicle with different heights. The first driving motor 451 is arranged on the hanging part 441 of the support plate 44 on the inner side (it should be noted that when the telescopic mechanism 3 is extended relative to the battery replacement main body 2, the hanging part 441 on the side of the support plate 44 close to the battery replacement main body 2 is the hanging part 441 on the inner side). The first driving motor 451 is located on the side of the battery tray 423 close to the battery replacement main body 2. The battery replacement mechanism 4 only needs to extend the battery tray 423 to the lower side of the battery replacement vehicle for battery replacement. The first driving motor 451 does not need to be extended to the lower side of the vehicle, and it runs on the outside of the vehicle body without interfering with the vehicle body of the battery replacement vehicle, avoiding occupying the space below the vehicle body. The first driving mechanism 45 only needs to extend the lead screw 452 and the nut 453 below the transmission plate 421 to achieve transmission. The lead screw 452 and the nut 453 occupy a small height space, which helps to reduce the height of the transmission plate 421 and the battery tray 423 located on the transmission plate 421. The first driving motor 451 is located on the hanging part 441, and the transmission plate 421 is located in the sunken cavity in the middle of the support plate 44, and there is a large height difference between them, which is not suitable for direct transmission connection. Therefore, by arranging a gear mechanism between the first driving motor 451 and the transmission plate 421, the first driving motor 451 and the transmission plate 421 are indirectly connected, and the stability and precision of the first driving mechanism 45 in driving the transmission plate 421 are improved through the reliability of the gear mechanism transmission. As for the gear mechanism, the gear mechanism can comprise a gear, and a gear is arranged between the first driving motor 451 and the lead screw 452 to achieve transmission. However, the diameter of this gear is relatively large, which occupies a lot of horizontal space and height space, which is not conducive to the flattening of the battery replacement mechanism 4.Therefore, in the technical scheme, the gear mechanism includes the driving gear 454 and the driven gear 455 that are engaged with each other, compared with the mode of arranging one gear between the first driving motor 451 and the lead screw 452 to realize transmission, the first driving motor 451 realizes transmission with the lead screw 452 through the driving gear 454 and the driven gear 455, which helps to appropriately reduce the size of the gear mechanism, reduce the occupied installation space, and is beneficial to compactness, miniaturization and flattening of the battery replacing mechanism 4.

[0075] In a preferred embodiment, as shown in Figures 3 to 7 , the number of the first driving mechanisms 45 is two, which are arranged in the middle region of the supporting plate 44, and the number of the transmission plates 421 is two and is arranged one by one corresponding to the first driving mechanisms 45 to carry the battery tray 423. In the technical scheme, the two first driving mechanisms 45 drive the two transmission plates 421 to move synchronously on the two sides of the supporting plate 44, the two transmission plates 421 support the battery tray 423 together, the supporting surface is large, the support stability of the battery pack is high, the battery tray 423 is more balanced in force, and the moving stroke of the battery tray 423 driven by the two first driving mechanisms 45 is more stable and reliable. The two first driving mechanisms 45 are arranged on the two sides of the supporting plate 44, which fully utilizes the installation space on the supporting plate 44, balances the force of the supporting plate 44, and improves the structural stability.

[0076] Regarding the structure of the transmission plate 421, in a preferred embodiment, as shown in Figure 7 , Figure 10 and Figure 11 , the transmission plate 421 is in the shape of a U-shaped character, the lead screw 452 is arranged corresponding to the middle arched region of the U-shaped character, the outer edges of the U-shaped character are respectively connected with the supporting plate 44 through the guide mechanism 46, and the upper surfaces of the outer edges of the U-shaped character are used to arrange the plurality of elastic members 422 that realize floating of the battery tray 423. Those skilled in the art can understand that the transmission plate 421 is in the shape of a U-shaped character, compared with the flat plate structure, the strength of the U-shaped character structure is higher, and the anti-deformation ability is stronger, the middle arched region of the U-shaped character provides a transmission space below the supporting plate 44, and the transmission of the lead screw 452 in the region helps to realize compact structure, the outer edges of the U-shaped character are respectively connected with the supporting plate 44 through the guide mechanism 46, and the elastic members 422 used to support the battery tray 423 are also arranged on the outer edges of the U-shaped character, so that the area below the contact area of the transmission plate 421 and the elastic members 422 is carried by the guide mechanism 46 instead of being in a suspended state, therefore, when the battery pack is subjected to gravity, the gravity of the battery pack is transmitted to the supporting plate 44 through the elastic members 422, the transmission plate 421 and the guide mechanism 46, which provides stable support for the battery pack and reduces the risk of deformation of the transmission plate 421. In addition, as shown in Figure 7As shown, the upper surface of the outer edge of the "J" shape is provided with a plurality of U-shaped slots 424 that cooperate with the card plate on the battery tray 423 to drive the battery tray 423 to move synchronously. The cooperation between the card plate and the U-shaped slots 424 can, on the one hand, limit the horizontal position of the battery tray 423 so that it can move synchronously with the transmission plate 421 along the telescopic direction. On the other hand, the cooperation between the card plate and the U-shaped slots 424 can also guide the up and down floating of the battery tray 423.

[0077] Furthermore, if Figures 3 to 7 as well as Figure 12 As shown, the battery swap mechanism 4 also includes a second drive mechanism 47 provided between the two first drive mechanisms 45 along the telescopic direction, which is used to drive the support plate 44 to move in a direction perpendicular to the telescopic direction to adjust the position of the battery tray 423 until it matches the position of the battery pack. It can be understood by those skilled in the art that battery swap vehicles usually replace batteries on a battery swap platform, and the battery swap vehicle is parked at the corresponding battery swap position. At this battery swap position, the battery swap device 100 can perform the battery pack replacement operation, but the battery swap vehicle is mostly driven by the driver based on experience and visual observation to drive the battery swap vehicle into the battery swap platform. Therefore, most of the time, the battery swap vehicle cannot be accurately parked at the battery swap position, and the body of the battery swap vehicle is often moved forward or backward relative to the battery swap position, resulting in a position deviation between the battery pack on the vehicle and the battery swap device 100, requiring the driver to adjust the body position multiple times, which affects the normal battery swap process of the battery swap device 100 and reduces the battery swap efficiency. For lighter passenger cars, a translation mechanism is usually set up on the battery swap platform. The battery swap vehicle is parked on the translation mechanism, and the battery swap vehicle is adjusted forward and backward through the translation mechanism until the battery swap position requirements are met. However, for large and heavy-duty battery swap vehicles such as light trucks and heavy trucks, the cost of setting up a translation mechanism on the battery swap platform to adjust the battery swap vehicle is too high, and the adjustment is difficult. Therefore, in the present technical solution, the second driving mechanism 47 is used to drive the pallet 44 to move in a direction perpendicular to the extension and retraction direction, thereby causing the battery tray 423 on the pallet 44 to move in a direction perpendicular to the extension and retraction direction. The direction perpendicular to the extension and retraction direction is a direction parallel to the body of the battery-swapping vehicle. When the driver parks the battery-swapping vehicle in front of or behind the battery-swapping position based on experience and visual observation and a deviation occurs, the position of the pallet 44 can be adjusted in a direction parallel to the body of the battery-swapping vehicle by the second driving mechanism 47. Since the pallet drives the battery-carrying part 42 to move synchronously, a method is formed in which the battery tray 423 autonomously and faster searches for the battery pack on the battery-swapping vehicle, so as to adjust the position of the battery tray 423 until it matches the position of the battery pack, replacing the existing method in which the driver adjusts the body position multiple times to find the battery-swapping position. Moreover, adjusting the position of the battery tray 423 in a direction parallel to the body of the battery-swapping vehicle is easier to implement and has a simple structure, which helps to reduce the difficulty of battery swapping, save the cost of battery swapping stations, and improve the efficiency of battery swapping.

[0078] Furthermore, if Figure 7 、 Figure 9 and Figure 12 As shown, the second drive mechanism 47 includes a second drive motor 471 provided above the hanging portion 441 and between the two first drive motors 451, a synchronization shaft 472 that passes through the pallet 44 along the telescopic direction and is connected to the pallet 44, two driven wheels 473 fixed to both ends of the synchronization shaft 472, and a driving wheel 474 that meshes with one of the driven wheels 473 and is transmission-connected to the output shaft of the second drive motor 471. Racks 475 that mesh with the driven wheels 473 are provided on the two crossbeams 411 to drive the pallet 44 to move relative to the bracket 41. In this technical solution, the second drive mechanism 47 includes the second drive motor 471 and a gear rack 475 mechanism consisting of the driving wheel 474, the driven wheel 473, and the rack 475. The reliability of the gear rack 475 transmission mechanism can be used to improve the stability and accuracy of the second drive mechanism 47 in the process of driving the pallet 44 to move. The rack 475 is mounted on the crossbeam 411. When the second drive motor 471 is running, the rotation of the driving wheel 474 drives the driving wheel 474 to mesh with the rack 475, thereby driving the second drive motor 471 to move. Since the second drive motor 471 is arranged on the hanging portion 441 of the support plate 44, the second drive motor 471 drives the support plate 44 to move synchronously. Compared with the method of setting a gear between the second drive motor 471 and the rack 475 to achieve transmission, the second drive motor 471 achieves transmission through the driving wheel 474 and the driven wheel 473 and the rack 475, which helps to appropriately reduce the size of the gear rack 475 mechanism and reduce the installation space it occupies, which is conducive to the compact, miniaturized and flat structure of the battery exchange mechanism 4. The two driven wheels 473 are connected by a synchronization shaft 472, and the synchronization shaft 472 is connected to the support plate 44. When the second drive motor 471 drives the driving wheel 474 on one side to rotate, the driven wheels 473 on both sides are engaged with the driving wheel 474 and the synchronization shaft 472, so that the driven wheels 473 on both sides operate synchronously. The driven wheels 473 on both sides are engaged and move along the corresponding racks 475 at both ends of the battery exchange mechanism 4, thereby driving the support plate 44 to move together through the synchronization shaft 472. The force on the support plate 44 is more balanced, and the moving stroke is more stable and reliable. In addition, the second drive motor 471 is arranged on the hanging part 441 on the inner side of the support plate 44 like the first drive motor 451. The second drive motor 471 is located on the inner side of the battery tray 423 as a whole. The battery exchange mechanism 4 only needs to extend the battery tray 423 under the battery exchange vehicle for battery exchange. The first drive motor 451 and the second drive motor 471 do not need to be extended under the vehicle. The two run on the outside of the vehicle body without interfering with the body of the battery exchange vehicle, avoiding occupying the space under the vehicle body.

[0079] In a preferred embodiment, Figure 7 、 Figure 9 andFigure 12 As shown, two racks 475 are respectively arranged on the inner side wall of the crossbeam 411, and two through-holes 442 are respectively opened on the two hanging parts 441 to avoid the driven wheel 473 and the driving wheel 474. In this technical solution, the racks 475 are arranged on the inner side wall of the crossbeam 411, utilizing the inner space of the crossbeam 411, which contributes to a compact structure. At the same time, it also facilitates the driven wheel 473 engaged with the racks 475 to sink relative to the crossbeam 411, thereby sinking the synchronization shaft 472, so that the synchronization shaft 472 can be connected to the support plate 44 designed to sink relative to the bracket 41. Moreover, this design effectively widens the distance between the second drive motor 471 and the racks 475, thereby providing space for the installation of the driving wheel 474 and the driven wheel 473. The through-holes 442 avoid the driven wheel 473 and the driving wheel 474, so that the driven wheel 473 and the driving wheel 474 can achieve meshing transmission at the position of the through-holes 442.

[0080] In a preferred embodiment, Figure 7 and Figure 9 As shown, two reinforcing plates 443 are provided in the middle area of ​​the support plate 44 along the extension direction. The two reinforcing plates 443 extend to the hooking parts 441 connected to the two ends to form an accommodating space for accommodating the synchronization shaft 472. Two reinforcing plates 443 are provided in the middle area of ​​the support plate 44 along the extension direction. The reinforcing plates 443 reinforce the structure of the support plate 44, thereby improving the strength and the ability to bear high loads. When dealing with heavy battery packs, the risk of deformation is reduced. The synchronization shaft 472 is located between the two reinforcing plates 443. The two ends of the synchronization shaft 472 are connected to the support plate 44. Specifically, the two ends of the synchronization shaft 472 can be rotatably connected to the support plate 44 through bearings, so that the synchronization shaft 472 rotates relative to the support plate 44 under the drive of the driven wheel 473 engaged with the driving wheel 474, thereby driving the driven wheel 473 on the other side to rotate. The synchronizing shaft 472 is located in the center of the support plate 44 as a whole. When the support plate 44 is subjected to translational force, the forces on both sides of the synchronizing shaft 472 are balanced, which helps to improve translational stability.

[0081] In a preferred embodiment, Figure 6 、 Figure 13 and Figure 14As shown, the battery swap mechanism 4 also includes a lifting drive mechanism 48 connected to the bottom surface of the battery tray 423, which is used to drive multiple unlocking pins 43 to move up and down relative to the battery tray 423 to lock and unlock the battery pack. In this technical solution, the unlocking pin 43 can be raised and lowered relative to the battery tray 423, so that the adaptability of the battery pack locking mechanism to different models, sizes, and installation positions on the battery swap vehicle can be improved by adjusting the height of the unlocking pin 43. For example, when the battery pack locking mechanism is in a higher position, the position of the unlocking pin 43 can be raised, and when the battery pack locking mechanism is in a lower position, the position of the unlocking pin 43 can be lowered. The unlocking pin 43 can be driven up and down by the lifting drive mechanism 48 to realize the locking and unlocking of the battery pack, so that the lifting and lowering of the unlocking pin 43 required for the locking and unlocking process of the battery pack on the battery swap vehicle can be realized not only by the overall lifting of the battery swap body 2, but also by the lifting drive mechanism 48. Compared with the locking and unlocking of the battery pack by the unlocking pin 43 through the overall lifting of the battery swap body 2, the locking and unlocking of the battery pack by driving the unlocking pin 43 up and down by the lifting drive mechanism 48 does not depend on the lifting of the battery swap body 2. During the locking and unlocking process, the telescopic fork 31 and the battery carrying part 42 are in a relatively static state. The fewer parts that are lifted and moved, the more helpful it is to improve the accuracy of the lifting of the unlocking pin 43 and the reliability of locking and unlocking, thereby improving the safety and efficiency of the battery swap process, and increasing the flexibility of the battery swap equipment 100, making the battery pack replacement process more efficient and safe.

[0082] Furthermore, if Figure 6 、 Figure 13 and Figure 14 As shown, in the vertical direction of the telescopic direction, a plurality of unlocking pins 43 are provided at both ends of the battery tray 423, and the plurality of unlocking pins 43 located at the same end of the battery tray 423 are driven to rise and fall synchronously by the same lifting drive mechanism 48. In this technical solution, the provision of a plurality of unlocking pins 43 can match the technology of providing a plurality of battery pack locking mechanisms for battery-swap vehicles, so as to achieve synchronous action of a plurality of battery pack locking mechanisms to realize locking and unlocking. Moreover, the unlocking pins 43 at both ends of the battery tray 423 can also correspond to different levels of locking and unlocking, for example, the unlocking pin 43 at one end corresponds to the first level locking and unlocking, and the unlocking pin 43 at the other end corresponds to the second level locking and unlocking, and the first level locking and unlocking and the second level locking and unlocking can be completed synchronously. The two unlocking pins 43 located at the same end of the battery tray 423 are driven to rise and fall synchronously by a lifting drive mechanism 48, which simplifies the drive structure and improves the synchronization of locking and unlocking.

[0083] Furthermore, if Figure 14 and Figure 15As shown, multiple unlocking pins 43 located at the same end of the battery tray 423 are spaced apart along the extension and retraction direction. The lifting drive mechanism 48 includes an electric push rod 481, a connecting rod 482, and a transmission rod 483 corresponding to each of the multiple unlocking pins 43. The connecting rod 482 is connected to the electric push rod 481, and the ends of the transmission rod 483 are respectively hinged to the connecting rod 482 and the unlocking pin 43. The electric push rod 481 drives the connecting rod 482 to translate along the extension and retraction direction, and the transmission rod 483 drives the unlocking pin 43 to move up and down. In this technical solution, when the electric push rod 481 drives the connecting rod 482 to translate, the connecting rod 482 drives all the transmission rods 483 to rotate relative to the connecting rod 482, so that the transmission rod 483 drives the unlocking pin 43 to move up and down. This makes the lifting and moving of the unlocking pin 43 stable and reliable, and improves the efficiency of locking and unlocking.

[0084] Furthermore, if Figure 13 、 Figure 14 and Figure 15 As shown, the bottom of the battery tray 423 is provided with a mounting frame 425 corresponding to the locking and unlocking drive mechanism. The electric push rod 481 is installed on the mounting frame 425 and drives the connecting rod 482 to translate in the telescopic direction within the mounting frame 425. The mounting frame 425 is provided with a first guide structure to guide the translation of the connecting rod 482 and a second guide structure to guide the lifting and lowering movement of the unlocking pin 43. In this technical solution, the mounting frame 425 is installed at the bottom of the battery tray 423 and serves as a bearing structure for the lifting drive mechanism 48, improving the portability of the assembly of the lifting drive mechanism 48 and allowing the lifting drive mechanism 48 to be raised and lowered with the battery tray 423. Specifically, the mounting frame 425 can be installed on the bottom of the battery tray 423 by welding or bolts. The first guide structure guides the translation of the connecting rod 482, allowing the connecting rod 482 to translate stably and smoothly, and the second guide structure guides the lifting and lowering movement of the unlocking pin 43, allowing the unlocking pin 43 to be lifted and lowered stably and smoothly. Preferably, the first guide structure is a horizontal guide slide hole 4251 provided in the mounting frame 425, and a first guide protrusion 484 is provided on the connecting rod 482. The first guide protrusion 484 slides horizontally along the horizontal guide slide hole 4251 to guide the translation of the connecting rod 482. The second guide structure is a vertical guide slide hole 4252 provided in the mounting frame 425, and a second guide protrusion 485 is provided on the unlocking pin 43. The second guide protrusion 485 slides vertically along the vertical guide slide hole 4252 to guide the unlocking pin 43 to rise and fall.

[0085] In a preferred embodiment, if Figure 13 As shown, a plurality of battery positioning pins 426 are provided in the middle area of ​​the battery tray 423 for cooperating with the positioning holes at the bottom of the battery pack to drive the battery pack to move synchronously. Figure 4 、 Figure 5 and Figure 9As shown, the hanging part 441 at the outer end of the telescopic direction of the supporting plate 44 is provided with a plurality of vehicle body positioning pins, which are used to cooperate with the positioning holes on the battery swap vehicle to keep the position of the locking mechanism on the battery swap vehicle during the movement of the battery pack. In the technical solution, the battery tray 423 and the positioning pins provided on the supporting plate 44 can ensure the correct position of the battery pack during the battery swap process, prevent the battery pack from deviating during the transfer process and the locking and unlocking process, and thus improve the accuracy and safety of the battery swap. In addition, through the cooperation of the battery positioning pins 426 and the battery pack, a positioning and clamping effect is generated on the battery pack, so as to facilitate the synchronous movement of the battery tray 423 with the battery pack, and also make the battery pack more capable of bearing the unlocking force and improve the stability of the battery unlocking.

The battery swap platform 200 provides a parking and battery swapping space for the battery swap vehicle, and the battery swap vehicle can drive into the battery swap platform 200 from one end and then be parked at a corresponding battery swap position, at which the battery swap equipment 100 can perform the battery pack replacement operation. The battery swap equipment 100 can be arranged on one side or both sides of the battery swap platform 200 along the driving direction of the battery swap vehicle on the battery swap platform 200, so that one-sided and / or two-sided battery swap can be realized. Figure 16 The embodiment in which the battery swap equipment 100 is arranged on one side of the battery swap platform 200 is shown in Figure 17 The embodiment in which the battery swap equipment 100 is arranged on both sides of the battery swap platform 200 is shown in When two-sided battery swap is performed, the battery swap equipment 100 on one side can be used to disassemble the depleted battery, and the battery swap equipment 100 on the other side can be used to install the full battery. The battery swap equipment 100 on both sides can perform the battery swap operation synchronously and without interference, thereby improving the battery swap efficiency.
