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 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] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Utility Model Content

[0007] The present application provides a battery replacement device to solve at least one of the above technical problems.

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

[0009] 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 telescopic movement of the battery exchange device and the lifting and lowering movement of the battery exchange body enable battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between battery compartments of the battery rack to be achieved.

[0010] In the above scheme, the battery exchange body can be raised and lowered on the support frame to adjust the height of the battery exchange device. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. 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 the height corresponding to the battery compartment and then extended to take and place the battery, 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.

[0011] As a preferred embodiment of the present application, the battery swap device includes a telescopic mechanism and a battery swap mechanism provided on the top surface of the telescopic mechanism, the battery swap mechanism includes a battery tray, and an unlocking pin provided on the battery tray;

[0013] In the above solution, since the battery tray is a floating design, the floating characteristics of the battery tray allow it to adapt to the shape and state of different battery-swap vehicle chassis, maintain fit with the bottom of the vehicle, and thus achieve stable support for the battery pack. The unlocking pin is brought into contact with the unlocking point of the battery pack as the battery tray rises and falls and the telescopic mechanism moves, thereby unlocking or locking the battery pack, thereby improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0014] As a preferred embodiment of the present application, the battery exchange mechanism further includes a bracket, the battery tray is arranged higher than the bracket, and the bracket is provided with an elastic member for enabling the battery tray to float.

[0015] In the above solution, the bracket can support the battery tray and improve the stability of the battery tray. The elastic parts on the bracket make the battery tray floatable, which allows the battery tray to adapt to the shape and state of different battery-swapping vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety during the battery swap process. In addition, the elastic parts can enable the battery tray to adapt to different surfaces and pressures when contacting the bottom of the battery-swapping vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0016] As a preferred embodiment of the present application, the battery exchange mechanism further includes a bracket and a support plate arranged on the bracket, a sinking groove is formed on the support plate, and the battery tray is arranged in the sinking groove.

[0017] In the above solution, the battery tray is placed in the sunken groove on the pallet, which reduces the overall height of the battery tray on the bracket, makes the overall thickness of the battery swap mechanism smaller, and increases the battery swap space. In addition, the battery tray is placed in the sunken groove on the pallet, which can ensure the stable position of the battery tray during the battery swap process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery swap.

[0018] As a preferred embodiment of the present application, the battery tray is further provided with at least two battery positioning pins; the battery positioning pins are distributed in the middle area of the battery tray along the length direction of the battery tray.

[0019] In the above solution, the positioning pins provided on the battery tray can ensure the correct position of the battery pack during the battery replacement process, prevent displacement during movement or battery replacement, and thus improve the accuracy and safety of battery replacement. In addition, through the cooperation between the battery positioning pins and the battery pack, a positioning and clamping effect is produced on the battery pack, so as to facilitate the synchronous movement of the battery pack, and also enable the battery pack to better withstand the unlocking force, thereby improving the stability of battery unlocking. As a preferred embodiment of the present application, the battery replacement body includes a compartment and a movable assembly provided between the support frames and capable of being lifted and moved along the support frames, the battery replacement device is provided in the compartment, and the compartment can be rotatably connected to the movable assembly to adjust the direction of the battery replacement device.

At the same time, the box and the moving assembly are rotatably connected, which facilitates the adjustment of the angle of the box, thereby adjusting the extension angle of the telescopic mechanism. When the position of the battery to be transported or the parking position of the battery swap vehicle has a deflection angle, the telescopic mechanism can be accurately positioned and extended through rotation adjustment, which is conducive to efficient battery transport and completion of the battery swap action. At the same time, the adoption of the above scheme makes the battery rack setting method flexible and highly scalable, and can adapt to the installation conditions of different installation environments. While improving space utilization, it can also increase the battery pack storage capacity and make full use of the installation space on the side of the battery transport device.

[0026] In the above solution, 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 provided to form a mounting surface for mounting the compartment body. At the same time, the longitudinal beams also strengthen the overall structural strength of the linkage part to prevent deformation.

[0027] As a preferred embodiment of the present application, the battery exchange device also includes a rotating mechanism arranged between the body and the linkage part, and the rotating mechanism includes a slewing bearing assembly arranged between the mounting surface and the body and a driving assembly for driving the slewing bearing assembly to rotate.

[0028] In the above scheme, by providing a rotating mechanism, the smoothness and efficiency of the rotation of the car body relative to the linkage part can be improved, which is conducive to improving the battery transportation efficiency and battery replacement efficiency; at the same time, the rotatable connection between the car body and the linkage part is achieved by the rotating mechanism, that is, the rotating mechanism integrates the functions of carrying the car body and driving the car body to rotate relative to the linkage, saving additional connection structure, which is conducive to reducing the overall height of the equipment and better adapting to the battery replacement needs of heavy trucks;

[0029] At the same time, in the above scheme, the slewing bearing is a large bearing that can withstand comprehensive loads. It can not only realize the rotation of the car body, but also directly serve as a connecting part between the car body and the linkage part, eliminating the need to set up other connecting parts to connect the car body and the linkage part; at the same time, the axial dimension of the slewing bearing is small, which is convenient for reducing the height dimension of the connection structure between the moving component and the car body, thereby increasing the height dimension of the car body within the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the car body and expand the accommodating space of the car body.

[0030] As a preferred embodiment of the present application, the linkage portion also includes a mounting plate fixed at least to the bottom surface of the longitudinal beam, the surface of the mounting plate is formed with the mounting surface, and the driving assembly includes a rotating shaft arranged through the mounting surface, a gear arranged on the rotating shaft and meshing with the slewing support assembly, and a rotating motor arranged on the top surface of the mounting plate and used to drive the rotating shaft to rotate.

[0031] In the above scheme, this setting method can make full use of the installation space on the upper part of the mounting plate, and can avoid occupying the installation space between the mounting surface and the compartment, resulting in an increase in the vertical distance between the mounting surface and the compartment, which is beneficial to increase the height of the compartment within the limitation of the overall height size standard of the device to facilitate the installation of internal components of the compartment and expand the accommodating space of the compartment. The gear meshing transmission has the advantage of high transmission accuracy, so that the angle of rotation of the compartment can be controlled more accurately. At the same time, the motor also has the advantages of fast response speed and easy control.

[0032] As a preferred embodiment of the present application, the linkage portion further includes at least a first reinforcement portion arranged corresponding to the installation surface and / or a second reinforcement portion arranged close to the moving portion.

[0033] In the above scheme, the arrangement of the first reinforcement part and the second reinforcement part can improve the structural strength of the linkage part, thereby avoiding deformation or breakage of the linkage part due to the excessive weight of the compartment, the telescopic mechanism arranged inside the compartment, and the battery pack carried, thereby ensuring the safe and stable operation of the equipment.

By setting the reinforcement plate, the planning and arrangement of the installation space on the upper part of the installation plate can be realized, which is convenient for the setting of the aforementioned motor and other additional components, and can also provide partial protection for the motor and other additional components; by setting the transition connecting plate, the stability of the connection mechanism between the reinforcement plate and the longitudinal beam can be enhanced, thereby ensuring the reinforcement effect.

[0037] As a preferred embodiment of the present application, the second reinforcement portion includes a first reinforcement rib plate and a second reinforcement rib plate; wherein the first reinforcement rib plate 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, and the edge of the second reinforcement rib plate abuts against the side wall of the cross beam and the side wall of the longitudinal beam.

[0038] And / or, 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.

[0039] In the above solution, the first reinforcing ribs are located at the connection between the crossbeam and the longitudinal beam and are arranged on two opposing beam surfaces. They 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, which is usually the area with greater force. Through such reinforcement, the crossbeam and the longitudinal beam can better resist deformation and damage during battery pack transportation, ensuring the safety of the battery pack; the edges of the second reinforcing ribs abut 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 forces, ensuring that the battery transport device can maintain its structural stability even when subjected to large lateral pressure during battery pack transportation.

[0040] In the above scheme, 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 in 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.

Both settings can achieve the technical effect of lifting and lowering, and at least two sliders are arranged in sequence along the lifting direction to limit the running trajectory of the moving part, prevent deviation during the lifting process, and ensure stability.

[0043] As a preferred embodiment of the present application, the plurality of movable parts are arranged one by one at the end of the beam, and each of the movable parts includes a plurality of guide wheels that are in contact with two adjacent side walls of the corresponding column and a mounting seat for fixing the plurality of guide wheels.

[0045] 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.

[0046] In the above scheme, the setting of the roller and the rolling surface and the cooperation between the two can further ensure the stability of the moving path when the moving part moves up and down relative to the column, which is beneficial to ensure the adjustment accuracy of the height of the battery exchange device and the adjustment accuracy of the tilt angle.

[0050] In the above scheme, the function of the telescopic mechanism to move relative to the car body in a direction perpendicular to the telescopic direction is realized by the cooperation of the two structures of the fixed part and the movable part. The telescopic mechanism is provided with a fixed part, and the fixed part moves between the car body and the car body in a direction perpendicular to the telescopic direction through the sliding mechanism, thereby driving the entire telescopic mechanism to move relative to the car body in a direction perpendicular to the telescopic direction. The fixed part is provided with a telescopic part, and the telescopic part can be extended out of the car body to take and place the battery, and the telescopic movement function of the telescopic mechanism is realized by the movably connection between the telescopic part and the fixed part. At the same time, in the above scheme, the sliding mechanism is arranged between the car body and the telescopic mechanism, which can make full use of the installation space of the car body, and with this arrangement, the telescopic mechanism is always located directly below the telescopic mechanism, which is conducive to maintaining balance when the telescopic mechanism carries the battery pack.

[0053] In the above scheme, the setting of the guide mechanism can ensure the stability of the calibration movement path of the telescopic mechanism, which is conducive to improving the accuracy of the calibration movement so that the telescopic mechanism can be accurately aligned with the heavy-duty truck battery installation area, and the battery replacement work can be completed accurately and efficiently.

[0054] The rack is fixed on the body, the gear is fixed on the telescopic mechanism, the gear and the rack are meshed, and a driving motor is arranged on the telescopic mechanism to drive the gear to rotate. When the gear rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear drives the telescopic mechanism to move relative to the body in a direction perpendicular to the telescopic direction. The meshing of the above-mentioned gear and rack has the advantage of high transmission accuracy. At the same time, the driving motor also has the characteristics of fast response speed and easy control, which is conducive to achieving precise control of the sliding mechanism action to ensure that the telescopic mechanism can be accurately aligned with the battery pack installation area of the battery swap vehicle; the above-mentioned gear and rack are simple and compact, especially the height dimension in the vertical direction is small, which is conducive to reducing the height of the equipment to better adapt to the battery swap needs of heavy trucks.

The gear is driven to rotate by the drive motor so that it moves relative to the rack, thereby driving the battery exchange device to move synchronously.

[0056] In the above scheme, the frame structure adopted by the box body is conducive to reducing the dead weight of the box body while ensuring its structural strength and load-bearing capacity. The frame structure is convenient for increasing the available installation height inside the box body in the vertical direction, which is conducive to reducing the overall height of the equipment to better adapt to the battery replacement needs of heavy trucks. It is also convenient for the fixed installation of the telescopic mechanism and / or sliding mechanism, reducing the use of additional fasteners to further reduce weight; the extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism. When the gear rotates, it can only move in the direction perpendicular to the telescopic direction, thereby driving the telescopic mechanism to move in the direction perpendicular to the telescopic direction; the above-mentioned setting method can also make full use of the installation space on the lower part of the box body and the crossbeam, reduce the occupation of the vertical installation space, and facilitate the interaction of the telescopic mechanism with other devices and equipment such as battery replacement vehicles for battery packs; and by fixing the rack on the inner wall of the crossbeam, it is also conducive to shortening the transmission distance between the gear and the drive motor, thereby helping to reduce the fatigue failure rate of the motor output shaft / drive shaft, extend its service life, and also achieve a quieter effect.

[0060] In the above solution, positioning slots are provided on the crossbeam to secure the guide mechanism, thereby defining the trajectory of relative movement between the telescopic mechanism and the body. Placing the guide rails of the guide mechanism partially or entirely within the positioning slots improves the strength of the body while effectively reducing the overall thickness of the body and the telescopic mechanism. The sliding motion of the sliders fixed to the fixed portion and the guide rails enables the telescopic mechanism to move perpendicular to the telescopic direction.

[0067] In the above scheme, two independent lifting drive mechanisms are set up to independently control the lifting height on both sides of the battery swap body, so that the battery swap body can be tilted to adapt to different vehicle chassis; at the same time, the motor has the advantages of fast response speed and easy control, which is convenient for precise control of the lifting height and tilt angle of the battery swap device; the setting of the counterweight block can provide a safety measure for the battery swap device and the battery pack it carries, to avoid motor failure causing the battery swap device and the battery it carries to fall and be damaged directly.

[0068] As a preferred embodiment of the present application, the counterweight block is located on the end side adjacent to or on the opposite side of the battery exchange body.

[0069] In the above scheme, the counterweight block has two settings: one is set on the end side adjacent to the battery swap body to facilitate battery transportation between battery compartments, and the other is set on the other side opposite the battery swap body to optimize the space utilization efficiency of the battery swap station. Preferably, there are four columns to facilitate the grouped and independent installation of the sliding mechanism and the lifting drive mechanism. The above arrangement of the columns can provide sufficient support capacity while also reducing the obstruction of the columns on the circumferential direction of the box, making it easier for the box to adjust its direction.

[0074] With the above structure, the connecting part can be connected to the mounting part after the connecting part is connected. Compared with the aforementioned solution of directly setting the rotating shaft on the beam, it is more convenient to realize the matching of the rotating shaft with the through hole and the waist-shaped hole, which is conducive to reducing the difficulty of assembly.

[0095] 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.

[0096] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application may also be implemented in other ways than those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features of each embodiment may be combined with each other unless there is a conflict.

[0097] In addition, in the description of the present application, it should be understood that the terms "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application.

In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0100] like Figure 1-10 As shown, the present application discloses a battery swapping device, which includes a support frame 1, a battery swapping body 2 arranged between the support frames 1 and capable of lifting and moving, and a battery swapping device arranged in the battery swapping body 2 and capable of telescopic movement toward the outside of the support frame 1. Through the telescopic movement of the battery swapping device and the lifting and lowering movement of the battery swapping body 2, the battery swapping vehicle can be disassembled and assembled and / or the battery can be transferred between the battery compartments of the battery rack. Continue to refer to Figure 5 As shown, the battery exchange device includes a telescopic mechanism 4 and a battery exchange mechanism 3 provided on the top surface of the telescopic mechanism 4. The battery exchange mechanism 3 includes a floating battery tray 31 and an unlocking pin 311 provided on the battery tray 31; the battery tray 31 is extended into the bottom of the battery exchange vehicle through the telescopic movement of the telescopic mechanism 4, and the unlocking pin 311 unlocks or locks the battery pack with the rise and fall of the battery tray 31 and the telescopic movement of the telescopic mechanism 4. The battery exchange mechanism 3 also includes a bracket 32, and the battery tray 31 is arranged higher than the bracket 32. The bracket 32 is provided with an elastic member for making the battery tray 31 floatable. The elastic member enables the battery tray 31 to adapt to different surfaces and pressures when contacting the bottom of the battery exchange vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery exchange, but also ensures the simplicity of battery exchange operation and the safe replacement of battery packs. Continue to refer to Figure 5As shown, the battery swap mechanism 3 also includes a bracket 32 and a support plate 33 disposed on the bracket 32. The support plate 33 is formed with a sunken groove 331, and the battery tray 31 is disposed in the sunken groove 331. The placement of the battery tray 31 in the sunken groove 331 on the support plate 33 reduces the overall height of the battery tray 31 on the bracket 32, making the overall thickness of the battery swap mechanism 3 smaller and increasing the battery swap space. In addition, the placement of the battery tray 31 in the sunken groove 331 on the support plate 33 ensures the stable position of the battery tray 31 during the battery swap process, preventing displacement or tilting while carrying the battery pack, thereby improving the safety and reliability of the battery swap. The battery tray 31 is also provided with at least two battery locating pins 312; the battery locating pins 312 are distributed in the middle area of the battery tray 31 along the length of the battery tray 31. The locating pins provided on the battery tray 31 ensure the correct position of the battery pack during the battery swap process, preventing it from shifting during movement or swapping, thereby improving the accuracy and safety of the battery swap. In addition, the battery positioning pin 312 cooperates with the battery pack to produce a positioning and clamping effect on the battery pack, so as to facilitate the synchronous movement of the battery pack, and also make the battery pack more able to withstand the unlocking force, thereby improving the stability of battery unlocking. As a preferred embodiment of the present application, the battery exchange body 2 includes a compartment 21 and a mobile component 22 arranged between the support frame 1 and capable of being raised and lowered along the support frame 1. The battery exchange device is arranged in the compartment 21, and the compartment 21 can be rotatably connected to the mobile component 22 to adjust the direction of the battery exchange device.

[0101] In the above scheme, the battery exchange body 2 can be raised and lowered on the support frame 1 to adjust the height of the battery exchange device. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. 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 the height corresponding to the battery compartment and then extended to take and place the battery, 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. At the same time, by arranging the battery exchange device on the telescopic mechanism 4, the battery exchange equipment in this application integrates the functions of battery transportation and battery exchange, and because the battery tray 31 is a floating design, the floating characteristics of the battery tray 31 allow it to adapt to the shape and state of different battery exchange vehicle chassis, maintain contact with the bottom of the vehicle, thereby achieving stable support of the battery pack, and the unlocking pin 311 is brought into contact with the unlocking point of the battery pack as the battery tray 31 rises and falls and the telescopic movement of the telescopic mechanism 4, thereby unlocking or locking the battery pack, improving the accuracy and efficiency of disassembly and assembly of the battery pack. In addition, the elastic member can enable the battery tray 31 to adapt to different surfaces and pressures when contacting the bottom of the battery exchange vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery exchange, but also ensures the simplicity of battery exchange operation and the safe replacement of battery packs.

[0102] It should be noted that the present application does not specifically limit the specific structure of the battery tray 31, and it can adopt any one of the following embodiments:

[0103] Example 1: Reference Figure 5 As shown, the bottom of the sinking groove 331 is not lower than the bottom of the telescopic fork 41, so that the sinking groove 331 is recessed to a sufficient depth; the battery tray 31 is a two-piece tray, each tray piece matches the size of the sinking groove 331 and is floatable in the sinking groove 331 through an elastic member. In this technical solution, the bottom of the sinking groove 331 is not lower than the bottom of the telescopic fork 41, which can avoid interference between the support plate 33 and the structure connected below the telescopic fork 41, ensuring that the telescopic fork 41 can complete the telescopic action normally, and making the sinking groove 331 recessed to a sufficient depth to effectively reduce the overall height of the floating battery tray 31, while further facilitating the connection between the moving component 22 located below the support plate 33 and the support plate 33. Each tray piece matches the size of the sinking groove 331 and can be floated in the sinking groove 331 through elastic parts. The inner wall of the sinking groove 331 limits the tray piece, which can ensure the stability of the position of the tray piece during the battery replacement process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery replacement.

[0104] Example 2: Reference Figure 6 、 7As shown in Figures 8 and 9, the top surface of the pallet longitudinal beam is no higher than the top surface of the telescopic fork 41, and the bottom of the sinking groove 331 is slightly lower than the top surface of the pallet longitudinal beam. The battery tray 31 is an integrated tray so that the battery tray 31 does not contact the telescopic fork 41 after carrying the battery pack. In this technical solution, the top surface of the pallet longitudinal beam is no higher than the top surface of the telescopic fork 41, causing the pallet longitudinal beam to sink relative to the telescopic fork 41. The pallet 33 is mounted on the pallet longitudinal beam via a hanging portion. Therefore, the battery tray 31 on the pallet 33 sinks relative to the pallet longitudinal beam, thereby helping to reduce the height of the battery tray 31 on the pallet 33 and tend to be flat. The bottom of the sinking trough 331 is slightly lower than the top surface of the tray longitudinal beam, which not only ensures that the sinking trough 331 is recessed to a sufficient depth, but also helps to reduce the distance between the bottom surface of the pallet 33 and the moving assembly 22 located below the pallet 33 for driving the pallet 33 to move, so that the moving assembly 22 is reliably connected to the bottom surface of the pallet 33, thereby improving the stability of the moving assembly 22 driving the pallet 33. The battery tray 31 is an integrated tray with a large enough load-bearing surface to carry the battery pack. It has good adaptability for both small and large battery packs. For small battery packs, the integrated tray can even easily carry two battery packs at the same time. For large battery packs, the large enough load-bearing surface can improve the stability of the battery pack on the battery tray 31 and avoid up and down shaking. After carrying the battery pack, the battery tray 31 does not contact the telescopic fork 41 and will not interfere with the telescopic movement of the telescopic fork 41, ensuring that the telescopic fork 41 can stably extend and retract and smoothly complete the battery replacement.

[0105] Further, refer to Figure 1 、 2 As shown in Figures 9, 10, 11, and 12, the battery exchange body 2 includes a compartment 21 and a mobile component 22 that is arranged between the support frames 1 and can be lifted and moved along the support frames 1. The battery exchange device is arranged in the compartment 21, and the compartment 21 can be rotatably connected to the mobile component 22 to adjust the direction of the battery exchange device. By setting the mobile component 22, the compartment 21 is driven to move up and down along the support frame 1, thereby adjusting the height of the telescopic mechanism 4. At the same time, the compartment 21 and the mobile component 22 are rotatably connected, which facilitates the adjustment of the angle of the compartment 21, thereby adjusting the extension angle of the telescopic mechanism 4. When the position of the battery to be transported or the parking position of the battery exchange vehicle has a deflection angle, it can be accurately positioned and extended through rotation adjustment, which is conducive to efficient battery transportation and completion of the battery exchange action; at the same time, the above scheme makes the battery rack setting method flexible and scalable, and can adapt to the installation conditions of different installation environments. While improving space utilization, it can also increase the battery pack storage capacity and make full use of the installation space on the side of the battery transport device.

[0106] As a preferred embodiment of this application, refer to Figure 1As shown, the support frame 1 includes a plurality of columns 11 formed on the outer peripheral side of the body 21, the moving assembly 22 includes at least two moving parts 222 that are attached to the side walls of two adjacent columns 11 and can be raised and lowered, and a linkage part 221 connected between the at least two moving parts 222, and the body 21 can be rotatably connected to the bottom surface of the linkage part 221. By setting the column 11, stable support and limitation can be provided for the mobile component 22 and the box 21, thereby improving the stability of the connection structure between the box 21 and the mobile component 22, and can avoid the centrifugal force generated by the rotation of the box 21 relative to the mobile component 22 causing the mobile component 22 to shift or deflect, which is beneficial to ensuring the stable relative rotation between the mobile component 22 and the box 21; by setting the moving part 222 in the mobile component 22 to cooperate with the column 11 to realize the lifting function, and by setting the linkage part 221 to be rotatably connected to the box 21, it plays a role in positioning and supporting the box 21, which is beneficial to improving the stability of the connection mechanism between the box 21 and the linkage part 221; at the same time, the box 21 is set on the bottom surface of the linkage part 221, and the rotation control is realized by the top surface of the box 21, so that the bottom surface of the box 21 does not need to be set with any additional structure, and can be set close to the ground, so that it can adapt to the chassis of different models and batteries at different heights, which is beneficial to improving the scope of application of the battery transfer device of this application.

[0107] In one example, referring to Figure 9 and Figure 10 As shown, the linkage part 221 includes at least two cross beams 2211 connected to the corresponding moving parts 222 at both ends, and at least two longitudinal beams 2212 connected between the at least two cross beams 2211. The bottom surfaces of the at least two longitudinal beams 2212 are formed with mounting surfaces for mounting the body 21. In the above scheme, the linkage part 221 is provided with at least two cross beams 2211 for connecting with the moving parts 222 on both sides. By providing at least two longitudinal beams 2212 to form the mounting surface for mounting the body 21, the longitudinal beams 2212 also strengthen the overall structural strength of the linkage part 221 to prevent deformation. Figure 10 、 11As shown, the battery exchange device also includes a rotating mechanism arranged between the body 21 and the linkage part 221, and the rotating mechanism includes a slewing bearing 23 component arranged between the mounting surface and the body 21 and a driving component for driving the slewing bearing 23 component to rotate. By setting up a rotating mechanism, the smoothness and rotation efficiency of the car body 21 relative to the linkage part 221 can be improved, which is beneficial to improving the battery transportation efficiency and battery replacement efficiency; at the same time, the rotatable connection between the car body 21 and the linkage part 221 is realized by the rotating mechanism, that is, the rotating mechanism integrates the functions of carrying the car body 21 and driving the car body 21 to rotate relative to each other, saving additional connecting structure, which is beneficial to reducing the overall height of the equipment and better adapting to the battery replacement needs of heavy trucks; at the same time, in the above scheme, the slewing bearing 23 is a large bearing that can withstand comprehensive loads. It can not only realize the rotation of the car body 21, but also directly serve as a connecting member 28 between the car body 21 and the linkage part 221, eliminating the need to set up other connecting components to connect the car body 21 and the linkage part 221; at the same time, the axial dimension of the slewing bearing 23 is small, which is convenient for reducing the height dimension of the connection structure between the moving component 22 and the car body 21, so that the height dimension of the car body 21 can be increased within the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the car body 21 and expand the accommodation space of the car body 21.

[0108] In one example, referring to Figure 10 As shown, the linkage portion 221 also includes a mounting plate 2213 fixed to at least the bottom surface of the longitudinal beam 2212, and a mounting surface is formed on the surface of the mounting plate 2213. The driving component includes a rotating shaft 271 arranged through the mounting surface, a gear 242 arranged on the rotating shaft 271 and meshing with the slewing support 23 component, and a rotating motor 241 arranged on the top surface of the mounting plate 2213 and used to drive the rotating shaft 271 to rotate.

[0109] In the above scheme, this setting method can make full use of the installation space on the upper part of the mounting plate 2213, and can avoid occupying the installation space between the mounting surface and the compartment 21, resulting in an increase in the vertical distance between the mounting surface and the compartment 21, which is beneficial to increase the height dimension of the compartment 21 within the limitation of the overall height dimension standard of the device to facilitate the installation of internal components of the compartment 21 and expand the accommodating space of the compartment 21. The meshing transmission of the gear 242 has the advantage of high transmission accuracy, so that the rotation angle of the compartment 21 can be more accurately controlled. At the same time, the motor also has the advantages of fast response speed and convenient control.

[0110] As a preferred embodiment of the present application, the linkage portion 221 further includes at least a first reinforcement portion provided in correspondence with the mounting surface and / or a second reinforcement portion provided near the movable portion 222. The provision of the first and second reinforcement portions can enhance the structural strength of the linkage portion 221, thereby preventing deformation or breakage of the linkage portion 221 due to excessive weight of the body 21, the telescopic mechanism 4 provided therein, and the battery pack carried, thereby ensuring safe and stable operation of the device.

[0111] It should be noted that the present application does not specifically limit the structure and configuration of the first reinforcement portion and the second reinforcement portion, and any one of the following embodiments may be adopted:

[0112] Example 3: Reference Figure 9 As shown, the first reinforcement portion includes a plurality of reinforcement plates 251, the two ends of the reinforcement plates 251 are respectively fixedly connected to the longitudinal beams 2212 at the two ends, and the bottom of the reinforcement plates 251 is fixedly connected to the mounting plate 2213. Preferably, a transition connection plate 252 is further provided on the beam surface at the connection between the reinforcement plates 251 and the longitudinal beams 2212. The second reinforcement portion includes a first reinforcement rib plate 253 and a second reinforcement rib plate 254; wherein the first reinforcement rib plate 253 is provided at the connection between the cross beam 2211 and the longitudinal beam 2212 and is located on the two opposite beam surfaces of the cross beam 2211 and the longitudinal beam 2212, and the edge of the second reinforcement rib plate 254 abuts against the side walls of the cross beam 2211 and the side walls of the longitudinal beam 2212.

[0113] In the above solution, the reinforcing plate 251 has a simple structure and is easy to install. The above reinforcing structure does not occupy too much installation space above the mounting plate 2213. The installation of the reinforcing plate 251 can realize the planning and arrangement of the installation space above the mounting plate 2213, facilitate the installation of the aforementioned additional components such as the motor, and also provide partial protection for the motor and other additional components. The provision of the transition connecting plate 252 can enhance the stability of the connection mechanism between the reinforcing plate 251 and the longitudinal beam 2212, ensuring the reinforcement effect. The first reinforcing rib plate 253 is located at the connection between the cross beam 2211 and the longitudinal beam 2212 and is provided on two opposing beam surfaces. It can provide additional structural support in the horizontal and vertical directions, enhancing the stability and load-bearing capacity of the cross beam 2211 and the longitudinal beam 2212, especially at the connection, which is usually an area with greater stress. Through such reinforcement, the cross beam 2211 and the longitudinal beam 2212 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 254 abuts against the side walls of the cross beam 2211 and the longitudinal beam 2212, 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

[0114] Example 4: Reference Figure 11 As shown, the difference between this fourth embodiment and the third embodiment described above is that the second reinforcement portion includes a diagonal beam 255, which is disposed at the corner connection position of the horizontal beam 2211 and the longitudinal beam 2212. The two ends of the diagonal beam 255 are respectively connected to the horizontal beam 2211 and the longitudinal beam 2212, so that the diagonal beam 255, the horizontal beam 2211 and the longitudinal beam 2212 form a triangular frame structure. In the above solution, the triangular frame structure formed by the diagonal beam 255, the horizontal beam 2211 and the longitudinal beam 2212 can provide better stability and load-bearing capacity, especially at the corner portion where the horizontal beam 2211 and the longitudinal beam 2212 are connected, which is usually an area with concentrated force. The triangular structure has stability and can effectively distribute and bear the load, thereby enhancing the structural strength and durability of the entire battery transporter.

[0115] Further, refer to Figure 9 As shown, the movable portion 222 includes a connecting rod 2221 and vertically arranged fixed plates 2222 fixed at both ends of the connecting rod 2221. At least two sliders 54 are sequentially provided on the sidewall of each column 11 and one of the fixed plates 2222 along the lifting direction, and a slide rail that cooperates with the sliders 54 is provided on the sidewall of the other column 11. The fixed plate 2222 and the column 11 are slidably connected via the sliders 54 and the slide rail structure. As for whether the sliders 54 and the slide rail are specifically provided on the fixed plate 2222 or the column 11, there is no restriction. Both arrangements can achieve the technical effect of lifting. The presence of at least two sliders 54 in sequence along the lifting direction can define the running trajectory of the movable portion 222, prevent deviation during lifting, and ensure stability.

[0116] Further, refer to Figure 11 As shown, a plurality of movable parts 222 are provided at the ends of the crossbeam 2211 in a one-to-one correspondence, and each movable part 222 includes a plurality of guide wheels 26 that fit with two adjacent side walls of the corresponding column 11 and a mounting seat for fixing the plurality of guide wheels 26. The mounting seat is integrally formed with the crossbeam 2211, and / or a predetermined gap is reserved between the guide wheel 26 and the column 11, so that the movable assembly 22 drives the body 21 to tilt at a preset angle so as to cooperate with the chassis of the battery-exchange vehicle. In the above scheme, the arrangement of the roller and the rolling surface and the cooperation between the two can further ensure the stability of the moving path of the movable part 222 when it is raised and lowered relative to the column 11, which is conducive to ensuring the adjustment accuracy of the height of the battery-exchange device and the adjustment accuracy of the tilt angle.

[0117] As a preferred embodiment of the present application, a sliding mechanism is provided between the battery-exchanging device and the body 21, so that the battery-exchanging device can move relative to the body 21 in a direction perpendicular to the telescopic direction. By providing a sliding mechanism to drive the battery-exchanging device to perform calibration movements, it can adapt to the different positions of the battery pack installation areas on heavy-duty trucks of different vehicle lengths, which is beneficial to improving the versatility of the battery-exchanging equipment in the present application, and the sliding mechanism is provided between the fixed portion 411 and the body 21, which can make full use of the installation space inside the body 21; at the same time, it is also convenient to eliminate the position error between the battery-exchanging device and the heavy-duty truck battery pack installation area caused by the parking position offset, and to facilitate the removal and placement of batteries at different positions in the battery compartment, thereby helping to improve the accuracy and efficiency of battery replacement.

[0118] It should be noted that the present application does not specifically limit the specific configuration of the sliding structure, and it can adopt any of the following embodiments:

[0119] Embodiment 1: The sliding mechanism includes a fixed part 51 provided in the body 21 in a direction perpendicular to the telescopic direction and a movable part 52 movably provided on the fixed part 51. The battery replacement device includes a fixed portion 411 connected to the fixed part 51 or the movable part 52 and a telescopic portion 412 movably connected to the fixed portion 411. In the above scheme, the function of the telescopic mechanism 4 moving relative to the body 21 in a direction perpendicular to the telescopic direction is realized through the cooperation of the two structures of the fixed part 51 and the movable part 52. The telescopic mechanism 4 is provided with a fixed part 411, and the fixed part 411 moves in a direction perpendicular to the telescopic direction between the sliding mechanism and the body 21, thereby driving the entire telescopic mechanism 4 to move relative to the body 21 in a direction perpendicular to the telescopic direction. The fixed part 411 is provided with a telescopic part 412, and the telescopic part 412 can be extended out of the body 21 to take and place the battery. The telescopic movement function of the telescopic mechanism 4 is realized by the movably connection between the telescopic part 412 and the fixed part 411. At the same time, in the above scheme, the sliding mechanism is arranged between the compartment 21 and the telescopic mechanism 4, which can fully utilize the installation space of the compartment 21 and adopt this arrangement so that the telescopic mechanism 4 is always located directly below the telescopic mechanism 4, which is conducive to maintaining balance when the telescopic mechanism 4 carries the battery pack.

[0120] As a preferred example of this embodiment, refer to Figure 4 and Figure 5As shown, the fixed part 51 is a rack of preset length, the movable part 52 is a gear, the gear is provided on the battery exchange device, the rack is provided on the body 21, and the sliding mechanism also includes a drive motor 56 provided on the battery exchange device for driving the gear to rotate. Preferably, the battery exchange equipment also includes a guide mechanism provided between the body 21 and the battery exchange device, the guide mechanism includes a guide rail 53 and a slider 54 provided in pairs, one of the guide rail 53 and the slider 54 is fixed to the body 21, and the other is fixed to the battery exchange device. In the above scheme, the setting of the guide mechanism can ensure the stability of the calibration movement path of the telescopic mechanism 4, which is conducive to improving the accuracy of the calibration movement so that the telescopic mechanism 4 can be accurately aligned with the heavy truck battery installation area, and the battery exchange work can be completed accurately and efficiently. The rack is fixed on the body 21, the gear is fixed on the telescopic mechanism 4, the gear and the rack are meshed, and the gear is driven to rotate by arranging a drive motor 56 on the telescopic mechanism 4. When the gear rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear drives the telescopic mechanism 4 to move relative to the body 21 in a direction perpendicular to the telescopic direction. The above-mentioned gear and rack meshing has the advantage of high transmission accuracy. At the same time, the drive motor 56 also has the characteristics of fast response speed and easy control, which is conducive to achieving precise control of the sliding mechanism action to ensure that the telescopic mechanism 4 can be accurately aligned with the battery pack installation area of the battery-swap vehicle; the above-mentioned gears and racks are simple and compact in coordination, especially the small height dimension in the vertical direction, which is conducive to reducing the height of the equipment to better adapt to the battery-swap needs of heavy trucks.

[0121] Specifically, refer to Figure 4 and Figure 5As shown, the drive motor 56 is connected to the adjacent fixed part 411 through the fixed mounting plate 55. A mounting hole is provided on the fixed mounting plate 55, and the rotating shaft 271 of the drive motor 56 passes through the mounting hole and is connected to the gear; the bottom of the compartment 21 includes a crossbeam 211 arranged in a direction perpendicular to the telescopic direction of the battery exchange device, and the rack is fixedly connected to the crossbeam 211. The extension direction of the rack is perpendicular to the telescopic direction of the battery exchange device. The gear is driven to rotate by the drive motor 56 to move relative to the rack, thereby driving the battery exchange device to move synchronously. In the above scheme, the frame structure of the compartment 21 is conducive to reducing the dead weight of the compartment 21 while ensuring its structural strength and load-bearing capacity, and the frame structure is convenient for increasing the available installation height inside the compartment 21 in the vertical direction, which is conducive to reducing the overall height of the equipment to better adapt to the battery replacement needs of heavy trucks, and also facilitates the fixed installation of the telescopic mechanism 4 and / or the sliding mechanism, reducing the use of additional fasteners to further reduce weight; the extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism 4, and when the gear rotates, it can only move in the direction perpendicular to the telescopic direction, thereby driving the telescopic mechanism 4 to move in the direction perpendicular to the telescopic direction; the above-mentioned setting method can also make full use of the installation space on the lower part of the compartment 21 and the crossbeam 211, reducing the occupation of the vertical installation space to facilitate the interaction of the telescopic mechanism 4 with other devices and equipment such as battery replacement vehicles for battery packs; and by fixing the rack on the inner wall of the crossbeam 211, it is also beneficial to shorten the transmission distance between the gear and the drive motor 56, thereby reducing the fatigue failure rate of the motor output shaft / transmission shaft and extending its service life, and at the same time, it can also achieve a quieter effect.

[0122] Continue to refer to Figure 5 As shown, both ends of the fixed portion 411 are slidably connected to the crossbeam 211 via a guide mechanism. The two ends of the fixed portion 411 are located above the crossbeam 211. The lower portion of the fixed portion 411 includes a downwardly protruding limit base 4111, and the two ends of the limit base 4111 are clamped between the two crossbeams 211. The setting of the guide mechanism realizes the sliding connection between the fixed portion 411 and the crossbeam 211, so that the telescopic mechanism 4 can move in a direction perpendicular to the telescopic direction. The cooperation between the guide mechanism and the crossbeam 211 can also limit the movement trajectory of the telescopic mechanism 4. The setting of the limit base 4111 and its cooperation with the crossbeam 211 can ensure that the telescopic mechanism 4 can only move in a direction perpendicular to the telescopic direction, thereby further stabilizing the movement trajectory of the telescopic mechanism 4 and preventing angular deviation from affecting the accuracy of battery removal and placement.

[0123] As a preferred example of this embodiment, both crossbeams 211 are provided with positioning grooves 2111 facing the fixed portion 411, the guide rail 53 is at least partially located in the positioning grooves 2111, the slider 54 is fixedly connected to the fixed portion 411, and the slider 54 and the guide rail 53 are slidably matched. In the above scheme, by providing the positioning grooves 2111 on the crossbeams 211 for fixing the guide mechanism, the trajectory of relative movement between the telescopic mechanism 4 and the body 21 is defined. Placing part or all of the guide rails 53 in the guide mechanism in the positioning grooves 2111 can effectively reduce the overall thickness of the body 21 and the telescopic mechanism 4 while improving the strength of the body 21. By sliding the slider 54 fixed on the fixed portion 411 in cooperation with the guide rail 53, the telescopic mechanism 4 can be moved in a direction perpendicular to the telescopic direction. Specifically, the positioning groove 2111 is a C-shaped groove provided on the crossbeam 211 and opening toward the fixed portion 411. The guide rail 53 is provided on the bottom wall of the C-shaped groove. The slider 54 is fixed on the fixed portion 411 and slides with the guide rail 53, and the slider 54 is accommodated inside the C-shaped groove. In the above scheme, by providing the C-shaped groove, the available installation space of the crossbeam 211 is increased while ensuring the structural strength and bearing capacity of the crossbeam 211, and weight reduction is also achieved. Accommodating the guide assembly in the C-shaped groove directly avoids the guide assembly from occupying more vertical installation space during installation, which is conducive to reducing the height of the equipment to better meet the needs of heavy truck battery replacement. The C-shaped groove can also provide protection for the guide assembly, which is conducive to the long-term stable operation of the guide assembly.

[0124] Embodiment 2: The sliding mechanism is provided between the telescopic mechanism 4 and the battery-exchanging mechanism 3 , so that the battery-exchanging mechanism 3 moves on the telescopic mechanism 4 in a direction perpendicular to the telescopic direction.

[0125] As a preferred example of this embodiment, refer to Figure 6 、 7As shown in FIG8 , the battery swap mechanism 3 is arranged on the telescopic mechanism 4 through a bracket 32. Along the telescopic direction of the telescopic mechanism 4, the bracket 32 includes two bracket crossbeams 321 arranged side by side. The bracket crossbeam 321 is perpendicular to the telescopic direction of the telescopic mechanism 4. The two bracket crossbeams 321 are connected by two bracket longitudinal beams 322. The battery swap mechanism 3 is arranged in a space surrounded by the two bracket crossbeams 321 and the two bracket longitudinal beams 322. Both ends of the bracket crossbeam 321 are connected with a hanging ear plate 3211. The bracket crossbeam 321 sinks relative to the hanging ear plate 3211, and the hanging ear plate 3211 is hung and fixed on the telescopic mechanism 4. The top of the retracting mechanism 4, the power-exchanging mechanism 3 is mounted on two bracket beams 321, and the power-exchanging sliding mechanism includes a sliding drive motor 57 and a rack-and-pinion mechanism. The gear of the rack-and-pinion mechanism is connected to the output shaft of the sliding drive motor 57, and the rack of the rack-and-pinion mechanism is installed on the bracket beam 321. The gear of the rack-and-pinion mechanism includes a driving gear 582 and a driven gear 581. The driving gear 582 is connected to the output shaft of the sliding drive motor 57, and the driven gear 581 is respectively engaged with the driving gear 582 and the rack, thereby driving the power-exchanging mechanism 3 to move through the sliding drive motor 57. Preferably, there are two racks and two driven gears 581 respectively, and the two racks are respectively provided on the inner side walls of the two bracket beams 321. The two driven gears 581 are connected to the sliding drive motor 57 through a synchronous shaft. The synchronous shaft is connected to the power-exchanging mechanism 3, and the sliding drive motor 57 is connected to the upper part of the rack located on the inner side. Through the setting of the above-mentioned battery-changing sliding mechanism, the battery-changing mechanism 3 can continue to make calibrated movements relative to the telescopic mechanism 4 on the basis of the calibrated movement of the telescopic mechanism 4 relative to the body 21, so as to better adapt to the different positions of the battery pack installation areas on heavy-duty trucks with different vehicle lengths and the position error between the battery-changing mechanism 3 and the battery pack installation area of the heavy-duty truck caused by the parking position offset, which is conducive to further improving the battery-changing accuracy and efficiency.

[0126] As a preferred embodiment of the present application, the battery exchange body 2 in the present application can be tilted relative to the support frame, thereby driving the battery exchange device to deflect to adjust the horizontal angle of the battery exchange device, so that the battery exchange device can better adapt to the tilt of the vehicle chassis itself and / or the tilt of the vehicle chassis caused by factors such as vehicle load and uneven ground in the parking position, ensuring that the battery exchange device can fit well with the vehicle chassis when performing the battery exchange operation, which is conducive to the accurate and rapid disassembly and assembly of depleted batteries and fully charged batteries, and improving the battery exchange efficiency.

[0127] It should be noted that the present application does not specifically limit the tilting method of the battery replacement body 2, and it can adopt any of the following embodiments:

[0128] Implementation method three: reference Figure 9As shown, a rotating shaft 271 is provided on the end face of one of the linkage part 221 and the movable part 222, and a through hole 281 or a waist-shaped hole 282 is provided on the end face of the other, thereby realizing a rotational connection or a movable connection between the battery-swapping body 2 and the movable component 22. One end of the battery-swapping body 2 is rotationally connected to the sliding mechanism, and the other end is both rotationally connected to the sliding mechanism and can move relative to the sliding mechanism. While facilitating the adjustment of the tilt angle by making the heights of the two ends of the battery-swapping body 2 different, it is also convenient to eliminate the influence of the change in the horizontal distance between the battery-swapping body 2 and the sliding mechanism on the connection structure between the battery-swapping body 2 and the sliding mechanism when the battery-swapping body 2 is tilted, thereby facilitating the stability of the connection structure between the battery-swapping body 2 and the sliding mechanism.

[0129] Further, refer to Figure 2 As shown, it also includes two independent lifting drive mechanisms respectively arranged on both sides of the battery exchange body 2. The lifting drive mechanism includes a lifting motor 61. Each column 11 is provided with a vertically movable counterweight block 62. The counterweight block 62 is connected to the moving part 222 on the corresponding side through a chain 63. A sprocket is provided above each column 11 to cooperate with the chain on its side for transmission. The lifting motor drives the synchronous shaft to rotate, thereby simultaneously driving the two chains located on the same side of the battery exchange body 2 to drive the battery exchange body 2 to move vertically.

[0130] In the above scheme, two independent lifting drive mechanisms are set to independently control the lifting height on both sides of the battery exchange body 2, so that the battery exchange body 2 can be tilted to adapt to different vehicle chassis; at the same time, the motor has the advantages of fast response speed and easy control, which is convenient for accurately adjusting the lifting height and tilt angle of the battery exchange device; the setting of the counterweight block 62 can provide a safety measure for the battery exchange device and the battery pack it carries, so as to avoid the battery exchange device and the battery it carries from falling directly and being damaged due to motor failure. Preferably, the counterweight block 62 is located on the end side adjacent to the battery exchange body 2 or on the opposite side. In the above scheme, the counterweight block 62 has two setting positions, one is set on the end side adjacent to the battery exchange body 2, which is convenient for battery transportation between battery compartments, and the other is set on the other side opposite to the battery exchange body 2 to optimize the space utilization efficiency of the battery exchange station. Preferably, four columns 11 are provided to facilitate the independent installation of the sliding mechanism and the lifting drive mechanism in groups, and the columns 11 are arranged in the above-mentioned manner. While being able to provide sufficient support capacity, it can also reduce the obstruction of the body 21 in the circumferential direction by the columns 11, thereby facilitating the adjustment of the direction of the body 21. The arrangement of the connecting rod 2221 between the sliders 54 can enhance the structural strength of the sliding mechanism, and is also convenient for ensuring the synchronization of the lifting and lowering movements of the sliders 54 at both ends of the connecting rod 2221.

[0131] In one example, the linkage part 221 includes at least two beams 2211 whose two ends are respectively connected to the corresponding movable parts 222. A rotating shaft 271 is passed through the side walls of the beam 2211 near the two ends, and a shaft sleeve is fixed inside the beam to install the rotating shaft 271; the movable part 222 includes a connecting rod 2221 and a sliding part fixed at both ends of the connecting rod 2221 and slidingly matched with the column 11. A U-shaped lug 27 is provided on the side wall of the connecting rod 2221 facing the battery exchange body 2, and a through hole 281 or a waist-shaped hole 282 is provided on the lug side wall of the U-shaped lug 27.

[0132] In another preferred example, referring to Figure 9 As shown, the linkage part 221 includes at least two beams 2211 whose two ends are respectively connected to the corresponding moving parts 222, and the moving part 222 includes a connecting rod 2221 and a sliding part fixed at both ends of the connecting rod 2221 and slidingly matched with the column 11. A U-shaped lug 27 is provided on the side wall of the connecting rod 2221 near the two ends, and a rotating shaft 271 is passed through the U-shaped lug 27. Connecting parts 28 that match the spacing between the two sliding parts are respectively provided at both ends of the beam, and a through hole 281 or a moving groove is provided on the connecting part 28. The through hole 281 is a circular hole that passes through the connecting part 28 and matches the rotating shaft 271. The moving groove is a waist-shaped hole 282 that extends along the length direction of the beam and passes through the connecting part 28. With the above structure, the connecting member 28 can be connected to the mounting portion after the connecting member 28 is connected. Compared with the aforementioned solution in which the rotating shaft 271 is directly set on the crossbeam, the matching of the rotating shaft 271 with the through hole 281 and the waist-shaped hole 282 can be more conveniently achieved, which is conducive to reducing the difficulty of assembly.

[0133] In the above scheme, the rotating shaft 271 can be integrally formed with the crossbeam, thereby enhancing the connection strength between the rotating shaft 271 and the crossbeam; by providing a shaft sleeve, the rotating shaft 271 can be protected, and it is also convenient to lubricate between the shaft sleeve and the rotating shaft 271, thereby reducing the friction loss of the rotating shaft 271.

[0134] Implementation method 2: Reference Figure 10 As shown, a plurality of movable parts 222 are provided at the ends of the crossbeam in a one-to-one correspondence, and each movable part 222 includes a plurality of guide wheels 26 that fit in contact with two adjacent side walls of the corresponding column 11, and a mounting seat for fixing the plurality of guide wheels 26. The mounting seat is integrally formed with the crossbeam, and / or a predetermined gap is reserved between the guide wheel 26 and the column 11, so that the movable assembly 22 drives the car body 21 to tilt at a preset angle so as to cooperate with the chassis of the battery-swap vehicle.
