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 field of battery replacement technology, and specifically to a battery replacement device. 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 underground space of the battery swap vehicle, especially heavy truck battery swap vehicles, which are difficult to drive and park on platforms above the ground, the bottom space of the battery swap vehicle is more limited. If a battery swap device is used for battery swapping, the battery swap device needs to carry the depleted battery pack or the fully charged battery pack to move 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 truck 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] In addition, since the body of the battery-swapping vehicle may deflect when it stops to swap batteries, the battery-swapping device may not be accurately aligned with the battery-swapping vehicle at the battery-swapping position. On the one hand, this may cause the battery-swapping device to be unable to align with the battery pack for disassembly and assembly, making disassembly and assembly of the battery pack difficult. On the other hand, it may cause the placement of the disassembled battery pack in the battery-swapping device to be offset, resulting in unbalanced force on the battery-swapping device during subsequent transportation of the battery pack, making transportation unstable, and the offset of the battery pack may make it impossible to accurately align with the battery compartment.

[0007] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Summary of the Invention

[0008] The present application provides a battery replacement device to solve at least one of the above technical problems.

[0009] The technical solutions adopted in this application are:

[0010] A battery exchange device comprises: a fixed support frame, a battery exchange body arranged between the support frames and capable of being raised and lowered, and a battery exchange device arranged in the battery exchange body and capable of being telescopically moved to the outside of the support frame. The battery exchange device is telescopically moved and the battery exchange body is raised and lowered to enable battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between battery compartments of a battery rack to be performed through the telescopic movement of the battery exchange device and the raising and lowering movement of the battery exchange body. The battery exchange body comprises a body and a movable assembly arranged between the support frames and capable of being raised and lowered along the support frames. The battery exchange device is arranged in the body, and the body can be rotatably connected to the movable assembly to adjust the direction of the battery exchange device.

[0011] The battery swap body can be raised and lowered on the support frame, driving the battery swap device located inside the battery swap body to be raised and lowered, and adjusting the height of the battery swap device. When the battery needs to be removed and installed, the battery swap device is adjusted to a height corresponding to the vehicle chassis and then extended to realize the battery removal and installation of the battery swap vehicle. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, it is adjusted to a height corresponding to the battery compartment, and the battery swap device is extended to realize the battery removal and placement at the battery compartment, thereby realizing battery disassembly and installation operations on the battery swap vehicle and / or battery transfer operations between the battery compartment positions of the battery rack.

[0012] By setting up a retractable and movable battery swap device, when actually removing and installing the battery pack of the battery swap vehicle, and taking and placing the battery pack in the battery compartment, the battery swap device drives the battery swap device to rise and fall to a suitable height position, and then only the battery swap device needs to be extended, and there is no need to retract the battery swap device as a whole. Therefore, when removing and installing the battery pack of the battery swap vehicle, the battery swap device can be prevented from entering under the chassis of the battery swap vehicle as a whole and occupying the bottom space of the vehicle, reducing the space limitation of the battery swap device. The battery swap device does not need to move in the sunken space on the ground. When replacing the battery of a heavy truck, the problem of unreliable ground structure caused by multiple driving of the vehicle can be avoided, thereby further improving the long-term use stability of the battery swap equipment.

[0013] In addition, this solution uses a mobile assembly to move the car body up and down along the support frame, thereby adjusting the height of the battery swap device. At the same time, the car body and the mobile assembly are rotatably connected, making it easy to adjust the angle of the car body, and thus the extension angle of the battery swap device. When the battery swap vehicle is parked at a deflection angle, it can be precisely positioned and extended to achieve precise battery swapping.

[0014] The support frame includes a plurality of columns formed on the outer periphery of the box.

[0015] The moving assembly includes at least two moving parts that are arranged in contact with the side walls of two adjacent columns and can be lifted and lowered, and a linkage part connected between the at least two moving parts. The box body can be rotatably connected to the bottom surface of the linkage part.

[0016] By setting up multiple columns on the outer periphery of the car body, the cooperation between the columns and the moving components enables the moving components to drive the car body to rise and fall, thereby adjusting the height of the battery replacement device. By setting up a moving part in the moving component to cooperate with the columns to achieve the lifting function, and by setting up a linkage part to be connected to the car body for rotation, it plays a role in positioning and supporting the car body. In addition, the moving component is set above the car body, and the rotation control is achieved by the top surface of the car body, so that the bottom surface of the car body does not need to be set up with any additional structure, and it can be set close to the ground, so that the battery at any chassis height position can be replaced, which improves the scope of application.

[0017] The linkage portion includes at least two cross beams whose ends are respectively connected to the corresponding moving portions and at least two longitudinal beams connected between the at least two cross beams. The bottom surfaces of the at least two longitudinal beams are formed with mounting surfaces for mounting the car body.

[0018] In order to meet the extension of the battery replacing device, the compartment and the moving assembly need to be provided with an opening capable of allowing the battery replacing device to extend, which will result in the inconvenience of setting stress points in the circumferential direction of the compartment and the moving assembly. The stress connection between the two is concentrated on the bottom surface of the linkage part. The linkage part is provided with at least two cross beams for connecting with the moving parts on both sides. At least two longitudinal beams are arranged to form a mounting surface for mounting the compartment. The longitudinal beams strengthen the overall structural strength of the linkage part and prevent the linkage part from being deformed under stress when connected with the compartment.

[0019] The battery transfer device further comprises a rotating mechanism arranged between the compartment and the linkage part. The rotating mechanism comprises a slewing bearing assembly arranged between the mounting surface and the compartment and a driving assembly for driving the slewing bearing assembly to rotate.

[0020] The rotatable connection between the compartment and the linkage part is realized by the rotating mechanism. The rotating mechanism adopts a slewing bearing assembly and a driving assembly. The driving assembly is used to drive the slewing bearing assembly to rotate, thereby driving the compartment to rotate.

[0021] The linkage part further comprises at least one mounting plate fixed to the bottom surface of the longitudinal beam. The surface of the mounting plate forms the mounting surface. The driving assembly comprises a rotating shaft penetrating through the mounting surface, a gear arranged on the rotating shaft and engaged with the slewing bearing assembly, and a rotating motor arranged on the top surface of the mounting plate and used to drive the rotating shaft to rotate.

[0022] The linkage part further comprises at least one first reinforcing part corresponding to the mounting surface. The first reinforcing part comprises a plurality of reinforcing plates. The two ends of the reinforcing plates are respectively fixedly connected with the longitudinal beams at both ends. The bottom of the reinforcing plate is fixedly connected with the mounting plate.

[0023] Furthermore, the first reinforcing part comprises a plurality of reinforcing plates arranged between the longitudinal beams. The beam surface at the connection between the reinforcing plates and the longitudinal beams is further provided with a transition connecting plate.

[0024] Since the compartment contains the battery replacing device, a battery will be placed on the battery replacing device during use. The first reinforcing part is arranged to strengthen the structural strength of the linkage part and prevent deformation.

[0025] The first reinforcing part comprises a plurality of reinforcing plates. The reinforcing plates are fixedly connected with the longitudinal beams and the mounting surface, thereby enhancing the structural strength of the entire linkage part. In order to further enhance the structural strength of the linkage part, a transition connecting plate can be arranged on the beam surface at the connection between the reinforcing plates and the longitudinal beams.

[0026] The linkage part further comprises a second reinforcing part arranged close to the moving part.

[0027] The linkage part includes a second reinforcement part, which can improve the structural strength of the connection area between the linkage part and the moving part. Such reinforcement measures help ensure that during the battery pack transportation process, even under heavy loads, the battery transportation device can remain stable and avoid deformation or damage due to weight, thereby improving the safety and reliability of battery transportation.

[0028] The second reinforcement portion includes a first reinforcement rib plate and / or a second reinforcement rib plate;

[0029] The first reinforcing rib is provided at the connection portion of the cross beam and the longitudinal beam, and is located on two upper and lower opposite beam surfaces of the cross beam and the longitudinal beam;

[0030] The edge of the second reinforcing rib abuts against the side wall of the cross beam and the side wall of the longitudinal beam.

[0031] The first reinforcing rib is located at the connection between the crossbeam and the longitudinal beam, and is arranged on two opposite beam surfaces above and below. It can provide additional structural support in the horizontal and vertical directions, enhancing the stability and load-bearing capacity of the crossbeam and the longitudinal beam, especially at the connection point, which is usually an area with greater force. Through such reinforcement, the crossbeam and the longitudinal beam can better resist deformation and damage during the transportation of the battery pack, ensuring the safety of the battery pack. The edge of the second reinforcing rib abuts against the side walls of the crossbeam and the longitudinal beam, which can further improve the stability and deformation resistance of the battery transport device when subjected to lateral force, ensuring that during the transportation of the battery pack, even if it is subjected to greater lateral pressure, the battery transport device can maintain its structural stability.

[0032] The second reinforcement portion includes a diagonal beam, which is arranged at the corner connection position of the transverse beam and the longitudinal beam, and the two ends of the diagonal beam are respectively connected to the transverse beam and the longitudinal beam, so that the diagonal beam, the transverse beam and the longitudinal beam form a triangular frame structure.

[0033] The triangular frame structure formed by the cable-stayed beam, the cross beam and the longitudinal beam can provide better stability and load-bearing capacity, especially at the corner part where the cross beam and the longitudinal beam are connected, which is usually the area where the force is concentrated. The triangular structure is stable and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery transport device.

[0034] The projection of the cable-stayed beam in the horizontal plane at least partially falls within the installation surface.

[0035] The inclined angle and length of the inclined beam are further limited so that the landing point of one end of the inclined beam connected to the crossbeam is at the connection between the linkage part and the car body, so as to further strengthen the structural support strength of the connection between the linkage part and the car body, strengthen the connection stability between the linkage part and the car body, and at the same time help to improve the connection stability during the rotation of the car body.

[0036] The first reinforcement portion includes a third reinforcement rib, which is arranged on the top surface of the crossbeam and extends toward between adjacent crossbeams to be connected to the longitudinal beam at the bottom forming the mounting surface.

[0037] The third reinforcing rib plate strengthens the connection between the crossbeam and the longitudinal beam at the installation surface. Unlike the reinforcing plate, the third reinforcing rib plate is not provided in multiple pieces to strengthen the support strength between two longitudinal beams separately. Instead, it is connected as a whole to all the longitudinal beams at the installation surface, thereby improving the overall structural strength and ensuring the stability of the connection structure between each longitudinal beam and the crossbeam.

[0038] The plurality of movable parts are arranged at the end of the beam in a one-to-one correspondence, and each of the movable parts includes a plurality of guide wheels that fit with two adjacent side walls of the corresponding column and a mounting seat for fixing the plurality of guide wheels.

[0039] The guide wheel drives the moving part to move along the column, so that the linkage part connected to the moving part drives the box to move vertically, realizing the movement of the box along the support frame, so that the battery exchange device can be telescopically moved at different heights relative to the support frame, thereby replacing the battery packs at different heights of the battery rack.

[0040] Multiple moving parts are set up to strengthen the connection strength between the moving parts and the linkage parts, and the simultaneous movement of multiple moving parts is conducive to driving the linkage parts and the car body to achieve stable movement.

[0041] The mounting seat and the crossbeam are integrally formed, and / or,

[0042] A predetermined gap is reserved between the guide wheel and the column so that the moving component can drive the compartment to tilt at a preset angle so as to cooperate with the chassis of the battery-swap vehicle.

[0043] The mounting base and the crossbeam are integrally formed, which improves the stability between the mounting base and the crossbeam, strengthens the structural strength, and is beneficial to improving the overall stability of the battery swap device and the battery swap body during movement.

[0044] In actual working environments, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the extended part of the battery swap device needs to be adjusted. A predetermined gap is reserved between the guide wheel and the column. During the lifting process of the battery swap body, if the lifting height of one side is set higher, a height difference will be generated between this side and the other side of the car body, which will drive the car body and the battery swap device located inside the car body to form a tilt angle. At this time, the guide wheel on the higher side will offset toward the column. The predetermined gap provides offset space for the guide wheel, thereby ensuring that the extended part of the battery swap device can fit well with the tram chassis, facilitating the removal and transportation of the battery.

[0045] Due to the adoption of the above-mentioned technical solution, the beneficial effects achieved by this application are as follows: the battery exchange body can be raised and lowered on the support frame, driving the battery exchange device located in the battery exchange body to be raised and lowered, and adjusting the height of the battery exchange device. When it is necessary to remove and install the battery, the battery exchange device is adjusted to a height position corresponding to the car chassis and then extended to realize the battery removal and installation of the battery exchange vehicle. When it is necessary to place a low-charge battery in the battery compartment for charging or to take out a fully charged battery from the battery compartment, it is adjusted to a height corresponding to the battery compartment, and the battery exchange device is extended to realize the battery removal and placement at the battery compartment, thereby realizing battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between battery compartment positions of the battery rack.

[0046] By setting up a retractable and movable battery swap device, when actually removing and installing the battery pack of the battery swap vehicle, and taking and placing the battery pack in the battery compartment, the battery swap device drives the battery swap device to rise and fall to a suitable height position, and then only the battery swap device needs to be extended, and there is no need to retract the battery swap device as a whole. Therefore, when removing and installing the battery pack of the battery swap vehicle, the battery swap device can be prevented from entering under the chassis of the battery swap vehicle as a whole and occupying the bottom space of the vehicle, reducing the space limitation of the battery swap device. The battery swap device does not need to move in the sunken space on the ground. When replacing the battery of a heavy truck, the problem of unreliable ground structure caused by multiple driving of the vehicle can be avoided, thereby further improving the long-term use stability of the battery swap equipment.

[0047] In addition, this solution uses a mobile assembly to move the car body up and down along the support frame, thereby adjusting the height of the battery swap device. At the same time, the car body and the mobile assembly are rotatably connected, making it easy to adjust the angle of the car body, and thus the extension angle of the battery swap device. When the battery swap vehicle is parked at a deflection angle, it can be precisely positioned and extended to achieve precise battery swapping. BRIEF DESCRIPTION OF THE DRAWINGS

Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0062] This application provides a battery replacement device, such as Figures 1 to 6 As shown, it includes: a fixed support frame 1, a battery-changing body 2 arranged between the support frames 1 and capable of being raised and lowered, and a battery-changing device 3 arranged in the battery-changing body 2 and capable of being telescopically moved to the outside of the support frame 1. The battery-changing device 3 is telescopically moved and the battery-changing body 2 is raised and lowered to realize battery disassembly and assembly operations on the battery-changing vehicle and / or battery transfer operations between the battery compartment 5 of the battery rack 4; the battery-changing body 2 includes a compartment 6 and a movable assembly 7 arranged between the support frames 1 and capable of being raised and lowered along the support frame 1. The battery-changing device 3 is arranged in the compartment 6, and the compartment 6 can be rotatably connected to the movable assembly 7 to adjust the direction of the battery-changing device 3.

[0063] The battery exchange body 2 can be raised and lowered on the support frame 1, driving the battery exchange device 3 located in the battery exchange body 2 to be raised and lowered, and adjusting the height of the battery exchange device 3. When the battery needs to be removed and installed, the battery exchange device 3 is adjusted to the height corresponding to the car chassis and then extended to realize the battery removal and installation of the battery exchange vehicle. When a low-charged battery needs to be placed in the battery compartment 5 for charging or a fully charged battery needs to be taken out of the battery compartment 5, it is adjusted to the height corresponding to the battery compartment 5, and the battery exchange device 3 is extended to realize the battery removal and placement at the battery compartment 5, thereby realizing battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between the battery compartment 5 positions of the battery rack 4.

[0064] By providing a retractable and movable battery-exchanging device 3, when actually disassembling and installing the battery pack of the battery-exchanging vehicle, and taking and placing the battery pack in the battery compartment 5, the battery-exchanging device drives the battery-exchanging device 3 to rise and fall so that it is at a suitable height position, and then it is only necessary to extend the battery-exchanging device 3, and there is no need to retract the battery-exchanging device as a whole. Therefore, when disassembling and installing the battery pack of the battery-exchanging vehicle, the battery-exchanging device can be prevented from entering under the chassis of the battery-exchanging vehicle as a whole and occupying the bottom space of the vehicle, thereby reducing the space limitation of the battery-exchanging device. The battery-exchanging device does not need to move in the sunken space on the ground. When replacing the battery of a heavy truck, the problem of unreliable ground structure caused by multiple driving of the vehicle can be avoided, thereby further improving the long-term use stability of the battery-exchanging device.

[0065] In addition, this solution drives the body 6 to move up and down along the support frame 1 by setting a moving component 7, thereby adjusting the height of the battery-swapping device 3. At the same time, the body 6 and the moving component 7 are rotatably connected, which facilitates the adjustment of the angle of the body 6, thereby adjusting the extension angle of the battery-swapping device 3. When the battery-swapping electric vehicle is parked at a deflection angle, it can be accurately positioned and extended to achieve precise battery swapping.

[0066] It should be noted that in this solution, a battery rack 4 is provided at the support frame 1, and the battery rack 4 is provided with a battery compartment 5 position. The battery replacement body 2 can be raised and lowered so that it can be aligned with the battery compartment 5 position at different heights of the battery rack 4 through lifting, thereby realizing the taking and placing of the battery pack in the battery compartment 5 position.

[0067] In order to meet the telescopic movement requirements of the battery exchange device 3 and the rotation requirements of the body 6, openings need to be set around the mobile component 7 so that after the body 6 drives the battery exchange device 3 to rotate, the battery exchange device 3 can be telescopically moved in multiple directions, thereby realizing the disassembly and assembly of the battery of the battery exchange vehicle and the transfer of the battery between the battery compartments 5 of the battery rack 4. Therefore, it is inconvenient for the mobile component 7 to be connected to the body 6 through the side.

[0068] Preferably, if Figure 1 、 Figure 3 As shown, the support frame 1 includes a plurality of columns 11 formed on the outer peripheral side of the body 6, the movable assembly 7 includes at least two movable parts 71 that are attached to the side walls of two adjacent columns 11 and can be raised and lowered, and a linkage part 72 connected between the at least two movable parts 71, and the body 6 can be rotatably connected to the bottom surface of the linkage part 72.

[0069] By setting a plurality of columns 11 on the outer peripheral side of the body 6, the cooperation between the columns 11 and the moving assembly 7 enables the moving assembly 7 to drive the body 6 to rise and fall, thereby adjusting the height of the battery replacement device 3. The lifting function is achieved by setting a moving part 71 in the moving assembly 7 to cooperate with the columns 11, and the linkage part 72 is set to be connected to the body 6 for rotation, so as to play a role in positioning and supporting the body 6. In addition, the moving assembly 7 is set above the body 6, and the rotation control is achieved by the top surface of the body 6, so that the bottom surface of the body 6 does not need to be set with any additional structure, and can be set close to the ground, so that the battery at any chassis height position can be replaced, thereby improving the scope of application.

[0070] The rotation of the compartment 6 drives the battery exchange device 3 located inside it to rotate relative to the linkage part 72 at the same time, changing the orientation of the battery exchange device 3, so that the battery exchange device 3 can be telescopically moved in different directions. When the battery pack of the battery exchange vehicle needs to be disassembled and assembled, the compartment 6 rotates to cause the battery exchange device 3 to telescopically move toward the battery exchange vehicle. When the battery pack in the battery compartment 5 needs to be taken out and placed, the compartment 6 rotates to cause the battery exchange device 3 to face the opening of the battery compartment 5, and then the battery pack is taken out and placed by telescopically moving the battery exchange device 3 in the direction of the opening of the battery compartment 5. The rotation of the compartment 6 realizes the change of the working direction of the battery exchange device 3, and the interior of the compartment 6 is hollow, providing temporary storage space for the battery pack located in the battery exchange device 3. At the same time, it can also limit the position of the battery exchange device 3 and the battery pack, preventing the battery pack from being offset and falling during rotation, thereby improving the stability of the equipment.

[0071] Therefore, the force on the body 6 during rotation is concentrated on the bottom surface of the linkage part 72, and the linkage part 72 needs to be further supported and fixed. The battery swap station is equipped with a battery swap device 3 to realize the disassembly and assembly of the vehicle's battery pack and the placement of the battery pack at the battery rack 4. When the battery swap device 3 moves between the vehicle and the battery rack 4, it needs to switch directions between facing the battery swap vehicle and facing the battery rack 4. Therefore, the battery swap equipment needs to leave enough moving space for the battery swap device 3 so that it can smoothly complete the disassembly and placement of the battery pack. However, due to the movement requirements of the battery swap device 3, there will be fewer connection and fixing areas between the battery swap device 3 and other components, and the force surface is smaller, which may cause insufficient support strength. Therefore, it is necessary to improve the strength of the linkage part 72 to meet the structural stability of its connection with the body 6 and realize the stable rotation of the body 6.

[0072] Specifically, in one embodiment, the number of columns 11 is four, with two columns 11 provided on each side of the battery exchange body 2, and a movable part 71 is provided corresponding to the four columns 11, and each movable part 71 is connected to the linkage part 72. Each movable part 71 moves vertically along the corresponding column 11, driving the linkage part 72 connected thereto to achieve lifting and lowering movement. In this way, multi-position connection of the linkage part 72 is achieved, and the connection stability is improved. The multi-position connection drive is beneficial to the overall stability of the linkage part 72 in the process of driving the box 6 to rise and fall.

[0073] As a preferred embodiment of the present application, Figure 2 、 Figure 5 、 Figure 6 As shown, the linkage portion 72 includes at least two cross beams 721 whose ends are respectively connected to the corresponding moving portions 71 and at least two longitudinal beams 722 connected between the at least two cross beams 721 , and the bottom surfaces of the at least two longitudinal beams 722 are formed with mounting surfaces for mounting the car body 6 .

[0074] In order to meet the extension of the battery exchange device 3, the body 6 and the mobile component 7 need to be provided with openings that allow the battery exchange device 3 to extend, which will make it inconvenient to set force points in the circumference of the body 6 and the mobile component 7. The connection force between the two is concentrated on the bottom surface of the linkage part 72. The linkage part 72 is provided with at least two cross beams 721 for connecting with the mobile parts 71 on both sides. At least two longitudinal beams 722 are provided to form an installation surface for installing the body 6. The longitudinal beams 722 strengthen the overall structural strength of the linkage part 72 to prevent the connection between the linkage part 72 and the body 6 from being deformed by force.

[0075] At the same time, a crossbeam 721 and a longitudinal beam 722 are provided to cooperate with each other to realize strength support of the linkage part 72 in different directions. When the crossbeam 721 is connected to the movable part 71 , the force on the crossbeam 721 is dispersed through the longitudinal beam 722 to avoid stress concentration at the connection between the crossbeam 721 and the movable part 71 .

[0076] It should be noted that, in this embodiment, a plurality of transverse beams 721 and longitudinal beams 722 may be provided to enhance the structural strength and connection stability of the linkage portion 72 .

[0077] Furthermore, if Figure 3 As shown, the battery transport device also includes a rotating mechanism provided between the compartment 6 and the linkage portion 72 , and the rotating mechanism includes a slewing support assembly 724 provided between the mounting surface and the compartment 6 and a driving assembly 725 for driving the slewing support assembly 724 to rotate.

[0078] The rotatable connection between the body 6 and the linkage portion 72 is achieved by a rotating mechanism. The rotating mechanism adopts a slewing support assembly 724 and a driving assembly 725. The driving assembly 725 is used to drive the slewing support assembly to rotate, thereby driving the body 6 to rotate.

[0079] Furthermore, if Figure 4 、 Figure 5 As shown, the linkage portion 72 also includes a mounting plate 723 fixed to at least the bottom surface of the longitudinal beam 722, and the surface of the mounting plate 723 is formed with the mounting surface. The driving assembly 725 includes a rotating shaft 7251 arranged through the mounting surface, a gear 7252 arranged on the rotating shaft 7251 and meshing with the slewing support assembly, and a rotating motor 7253 arranged on the top surface of the mounting plate 723 and used to drive the rotating shaft 7251 to rotate.

[0080] The gear 7252 transmission method has a compact structure, stable and efficient transmission effect, a wide range of uses, is easy to install in different usage scenarios, and has high transmission reliability.

[0081] In one embodiment, Figure 1 、 Figure 2 As shown, the linkage portion 72 further includes a first reinforcement portion 726 provided at least corresponding to the mounting surface. The first reinforcement portion 726 includes a plurality of reinforcement plates 7261. The two ends of the reinforcement plates 7261 are fixedly connected to the longitudinal beams 722 at the two ends, and the bottom of the reinforcement plates 7261 is fixedly connected to the mounting plate 723.

[0082] and / or, such as Figure 4 、 Figure 5 As shown, the first reinforcement portion 726 includes a plurality of reinforcement plates 7261 provided between the longitudinal beams 722 , and a transition connection plate 7262 is further provided on the beam surface at the connection between the reinforcement plates 7261 and the longitudinal beams 722 .

[0083] Since the battery exchange device 3 is included in the compartment 6 and a battery is placed on the battery exchange device 3 during use, a first reinforcement portion 726 is provided to strengthen the structural strength of the linkage portion 72 and prevent deformation. The first reinforcement portion 726 includes a plurality of reinforcement plates 7261, which are fixedly connected to the longitudinal beam 722 and the mounting surface to enhance the structural strength of the entire linkage portion 72. To further enhance the structural strength of the linkage portion 72, a transition connecting plate 7262 can be provided on the beam surface at the connection between the reinforcement plates 7261 and the longitudinal beam 722.

[0084] When the two ends of the reinforcing plate 7261 are fixedly connected to the longitudinal beam 722 and the bottom is fixedly connected to the mounting surface, the structural strength at the mounting surface is enhanced by the reinforcing plate 7261, and the structural strength between the mounting surface and the longitudinal beam 722 is improved. When connected to the car body 6 through the mounting surface, the connection strength can be effectively improved, which is beneficial to maintaining the connection stability during the rotation of the car body 6.

[0085] When multiple reinforcing plates 7261 are provided between the longitudinal beams 722, the forces acting on the longitudinal beams 722 are dispersed, effectively improving the supporting strength of the longitudinal beams 722, and facilitating the improvement of the structural strength of the mounting surfaces between the longitudinal beams 722, thereby improving the force balance of the linkage portion 72 and further improving the connection stability of the battery exchange device 3 during operation. In this manner, since the reinforcing plates 7261 are provided between two adjacent longitudinal beams 722, the beam surface at the connection is subjected to forces, and a transition connecting plate 7262 is provided on the beam surface at the connection between the reinforcing plates 7261 and the longitudinal beams 722 to improve the supporting stability of the beam surface at the connection between the reinforcing plates 7261 and the longitudinal beams 722, which is conducive to further improving the fixing stability of the reinforcing plates 7261 and the structural strength of the connection between the reinforcing plates 7261 and the longitudinal beams 722.

[0086] Preferably, if Figure 5 、 Figure 6 As shown, the linkage portion 72 further includes a second reinforcement portion 727 disposed close to the moving portion 71 .

[0087] The linkage portion 72 includes a second reinforcement portion 727, which can improve the structural strength of the connection area between the linkage portion 72 and the movable portion 71. Such reinforcement measures help ensure that during the battery pack transportation process, even under heavy loads, the battery transportation device can remain stable and avoid deformation or damage due to weight, thereby improving the safety and reliability of battery transportation.

[0088] The second reinforcement portion 727 includes a first reinforcement rib plate 7271 and / or a second reinforcement rib plate 7272;

[0089] like Figure 6 As shown, the first reinforcing rib plate 7271 is provided at the connection portion of the cross beam 721 and the longitudinal beam 722 and is located on two upper and lower opposite beam surfaces of the cross beam 721 and the longitudinal beam 722;

[0090] like Figure 5 As shown, the edge of the second reinforcing rib plate 7272 abuts against the side wall of the cross beam 721 and the side wall of the longitudinal beam 722 .

[0091] The first reinforcing rib plate 7271 is located at the connection between the crossbeam 721 and the longitudinal beam 722, and is arranged on two upper and lower opposite beam surfaces, which can provide additional structural support in the horizontal and vertical directions, thereby enhancing the stability and load-bearing capacity of the crossbeam 721 and the longitudinal beam 722, especially at the connection part, which is usually an area with greater force. Through such reinforcement, the crossbeam 721 and the longitudinal beam 722 can better resist deformation and damage during the transportation of the battery pack, ensuring the safety of the battery pack. The edge of the second reinforcing rib plate 7272 abuts against the side walls of the crossbeam 721 and the longitudinal beam 722, which can further improve the stability and deformation resistance of the battery transport device when subjected to lateral force, ensuring that the battery transport device can maintain its structural stability even if it is subjected to greater lateral pressure during the transportation of the battery pack. Furthermore, the second reinforcement portion 727 includes a diagonal beam 7273, which is arranged at the corner connection position of the horizontal beam 721 and the longitudinal beam 722, and the two ends of the diagonal beam 7273 are respectively connected to the horizontal beam 721 and the longitudinal beam 722, so that the diagonal beam 7273, the horizontal beam 721 and the longitudinal beam 722 form a triangular frame structure.

[0092] The triangular frame structure formed by the cable-stayed beam 7273, the cross beam 721 and the longitudinal beam 722 can provide better stability and load-bearing capacity, especially at the corner part where the cross beam 721 and the longitudinal beam 722 are connected, which is usually an area with concentrated force. The triangular structure is stable and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery transport device.

[0093] Preferably, the projection of the cable-stayed beam 7273 in the horizontal plane at least partially falls within the installation surface.

[0094] The inclined angle and length of the inclined beam 7273 are further limited so that the landing point of one end of the inclined beam 7273 connected to the cross beam 721 is at the connection between the linkage part 72 and the car body 6, so as to further strengthen the structural support strength of the connection between the linkage part 72 and the car body 6, strengthen the connection stability between the linkage part 72 and the car body 6, and at the same time help to improve the connection stability during the rotation of the car body 6.

[0095] In addition, the first reinforcement portion 726 includes a third reinforcement rib 7263, which is disposed on the top surface of the cross beam 721 and extends toward between adjacent cross beams 721 to connect with the longitudinal beam 722 forming a mounting surface at the bottom.

[0096] The third reinforcing rib plate 7263 strengthens the strength of the connection between the cross beam 721 and the longitudinal beam 722 at the installation surface. The third reinforcing rib plate 7263 is different from the reinforcing plate 7261. It is not provided with multiple rib plates to strengthen the support strength between two longitudinal beams 722 respectively, but is connected as a whole to all the longitudinal beams 722 at the installation surface, thereby improving the overall structural strength and ensuring the stability of the connection structure between each longitudinal beam 722 and the cross beam 721 here.

[0097] It should be noted that there are many ways to combine and set the first reinforcement portion 726 and the second reinforcement portion 727. For details, please refer to the following embodiments:

[0098] Implementation method one:

[0099] like Figure 1 、 Figure 2 As shown, a first reinforcement portion 726 is provided, and the first reinforcement portion 726 includes a plurality of reinforcement plates 7261 whose two ends are fixedly connected to the longitudinal beam 722 and whose bottom is fixedly connected to the mounting plate 723. The structural strength at the mounting surface is increased by the fixed connection between the mounting plate 723 and the reinforcement plate 7261.

[0100] Implementation method 2:

[0101] like Figure 4 、 Figure 5 As shown, a first reinforcement portion 726 and a second reinforcement portion 727 are provided. The first reinforcement portion 726 includes a plurality of reinforcement plates 7261 provided between the longitudinal beams 722, and a transition connection plate 7262 and a second reinforcement rib plate 7272 are provided at the same time. In addition, in this embodiment, a longitudinal reinforcement beam 8 is provided, the two ends of which are respectively connected to the adjacent reinforcement plates 7261, and a fixed connection plate 9 is provided at the connection between the two ends of the longitudinal reinforcement beam 8 and the reinforcement plate 7261 to enhance the structural strength of the connection between the longitudinal reinforcement beam 8 and the reinforcement plate 7261.

[0102] Preferably, in this embodiment, while providing a plurality of longitudinal reinforcement beams 8 , a plurality of weight-reducing holes 81 are provided in the longitudinal reinforcement beams 8 to reduce the overall weight of the reinforcement structure, thereby reducing the burden of lifting and moving the battery exchange body 2 .

[0103] Implementation method three:

[0104] like Figure 6As shown, a first reinforcement part 726 and a second reinforcement part 727 are provided, the first reinforcement part 726 includes a third reinforcement rib 7263, and the second reinforcement part 727 includes a first reinforcement rib 7271 and a cantilever beam 7273. By means of the first reinforcement rib 7271, the cantilever beam 7273 and the third reinforcement rib 7263, the structural strength of the mounting surface and the structural strength of the connection between the end of the cross beam 721 and the longitudinal beam 722 are reinforced, thereby improving the support strength and connection strength of the linkage part 72, which is beneficial to improving the stability when the top of the car body 6 is connected to the bottom of the linkage part 72, thereby maintaining the stable driving movement of the car body 6 and the battery exchange device 3 located therein during the movement of the battery exchange body 2, as well as the connection stability of the car body 6 and the battery exchange device 3 during the rotation of the car body 6.

[0105] In one embodiment, a plurality of movable parts 71 are provided one by one at the ends of the beam 721 , and each movable part 71 includes a plurality of guide wheels 711 that fit with two adjacent side walls of the corresponding column 11 and a mounting seat 712 for fixing the plurality of guide wheels 711 .

[0106] The guide wheel 711 drives the moving part 71 to move along the column 11, so that the linkage part 72 connected to the moving part 71 drives the compartment 6 to move vertically, realizing the movement of the compartment 6 along the support frame 1, so that the battery exchange device 3 can be telescopically moved at different heights relative to the support frame 1, thereby replacing the battery packs at different heights of the battery rack 4.

[0107] A plurality of moving parts 71 are provided to strengthen the connection strength between the moving parts 71 and the linkage parts 72 , and the simultaneous movement of the plurality of moving parts 71 is conducive to driving the linkage parts 72 and the compartment 6 to achieve stable movement.

[0108] Furthermore, the mounting seat 712 and the crossbeam 721 are integrally formed, and / or,

[0109] A predetermined gap is reserved between the guide wheel 711 and the column 11 so that the moving component 7 can drive the body 6 to tilt at a preset angle so as to match the chassis of the battery-swap vehicle.

[0110] As a preferred implementation manner of this embodiment, the mounting seat 712 and the crossbeam 721 are integrally formed, and a predetermined gap is reserved between the guide wheel 711 and the column 11.

[0111] The mounting base 712 and the crossbeam 721 are integrally formed, which improves the stability between the mounting base 712 and the crossbeam 721, strengthens the structural strength, and is conducive to improving the overall stability of the battery exchange device 3 and the battery exchange body 2 during movement. In an actual working environment, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the protruding part of the battery exchange device 3 needs to be adjusted. A predetermined gap is reserved between the guide wheel 711 and the column 11. During the lifting and lowering process of the battery exchange body 2, if the lifting height of one side is set higher, a height difference will be generated between this side and the other side of the car body 6, driving the car body 6 and the battery exchange device 3 located in the car body to form an inclination angle. At this time, the guide wheel 711 on the higher side is offset toward the column 11. The predetermined gap provides offset space for the guide wheel 711, thereby ensuring that the protruding part of the battery exchange device 3 can fit well with the tram chassis, facilitating the disassembly and transportation of the battery.

[0112] Furthermore, if Figure 6 As shown, in this embodiment, the battery swap device includes a lifting drive mechanism 10 arranged on both sides of the battery swap body 2. The lifting drive mechanism 10 is provided with a motor 101 and a counterweight 102. The counterweight 102 is connected to the battery swap body 2 through a chain 103. A sprocket 104 is provided above the column 11 to cooperate with the chain 103 for transmission. The motor 101 drives the synchronous shaft 105 to rotate, thereby simultaneously driving the chain 103 on the same side of the battery swap body 2 to drive the battery swap body 2 to achieve lifting and movement. By setting the lifting heights on both sides of the battery swap body 2 to be different, the battery swap body 2 can be tilted along a preset angle.

[0113] It can be understood that the accompanying drawings illustrate the assembly connection relationship between the battery exchange body 2 and the battery rack 4. In actual applications, the heights of the battery exchange body 2 and the battery rack 4 can be set according to actual needs.

[0114] Anything not described in this application can be achieved by adopting or drawing on existing technologies.
