Description

[0001] This application claims priority to Chinese Patent Application No. 202410860695.4, filed on June 28, 2024. This application incorporates the entirety of the aforementioned patent application. TECHNICAL FIELD

[0002] The present application belongs to the field of vehicle battery replacement, and specifically relates to a battery carrying device for vehicle battery replacement and a battery replacement equipment. BACKGROUND

[0003] Compared with traditional fuel vehicles, electric vehicles have the advantages of green environmental protection and high intelligence, which are of great significance for energy saving and emission reduction and urban traffic intelligence, and therefore gradually become the strategic development direction of future automobile industry.

[0004] The existing charging methods of electric vehicles are generally divided into two types: battery replacement and direct charging. In the existing technology, a corresponding battery replacement station is built for the above-mentioned electric vehicles with battery replacement, and users drive to the battery replacement station to replace the battery when needed. Since there are various types of electric vehicles, the corresponding battery models, i.e., the battery styles, are also different, so that the battery packs have different lengths or widths. In order to enable the battery replacement station to replace batteries for various electric vehicles, some battery replacement stations are provided with multiple battery replacement positions and battery replacement equipment to adapt to different forms of battery packs. However, this method results in that the battery replacement equipment corresponding to the same type of battery pack is less, the battery replacement efficiency is low, and the compatibility of the battery replacement equipment is poor, which leads to poor user experience of battery replacement.

[0005] Therefore, there is a need for a battery replacement equipment that can adapt to battery packs of multiple specifications. CONTENT OF THE UTILITY MODEL

[0006] The present application provides a battery carrying device for vehicle battery replacement and a battery replacement equipment. By providing a movable battery carrying device, the problem of poor compatibility of the battery replacement equipment for different forms of battery packs is solved.

[0007] The technical solution adopted by the present application is as follows:

[0008] A battery carrying device for vehicle battery replacement is arranged on the top surface of a battery replacement equipment and used for carrying a battery pack during battery replacement. The battery carrying device for vehicle battery replacement comprises a first carrying part and a second carrying part arranged in parallel on the top surface of the battery replacement equipment. The first carrying part and the second carrying part are movably arranged along a preset direction to adapt to the specifications of the battery pack.

[0009] The present scheme adjusts the distance between the first bearing part and the second bearing part to adapt to different specifications of battery packs during battery replacement. The first bearing part and the second bearing part are arranged in parallel on the top surface of the battery replacement equipment and receive the battery pack to be replaced. According to different specifications of the battery pack, the first bearing part and the second bearing part are moved, wherein the first bearing part or the second bearing part can be moved alone or both can be moved to adapt to the specification of the battery pack to be replaced, improve the use compatibility of the battery bearing device, and the first bearing part and the second bearing part are moved along a preset path, which can further improve the accuracy of the moving distance, improve the adaptation effect of the battery bearing device on the battery pack, and is beneficial to the movement stability of the first bearing part and the second bearing part, avoiding path deviation caused by external force or other factors.

[0010] In addition, the battery bearing device is designed in a split manner, and two bearing parts are arranged respectively, which is beneficial to reducing the overall weight, reducing the consumption of materials, reducing the cost, facilitating popularization, and adapting to different specifications of battery packs.

[0011] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the first bearing part and the second bearing part are arranged in parallel along the width direction of the battery pack and are arranged to move back and forth along the width direction respectively to adapt to battery packs of different widths.

[0012] In this way, the adaptation to battery packs of different widths is realized. The first bearing part and the second bearing part can be moved respectively, and both can be moved simultaneously or one can be moved alone to adapt to different installation environments and different operating conditions, so that the adjustment mode is selected conveniently and quickly according to the actual situation, the battery replacement efficiency is improved, and the battery bearing device adapts to battery packs of different widths.

[0013] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the first bearing part and the second bearing part are arranged in parallel along the length direction of the battery pack and are arranged to move back and forth along the length direction respectively to adapt to battery packs of different lengths.

[0014] In this way, the adaptation to battery packs of different lengths is realized. The first bearing part and the second bearing part can be moved respectively, and both can be moved simultaneously or one can be moved alone to adapt to different installation environments and different operating conditions, so that the adjustment mode is selected conveniently and quickly according to the actual situation, the battery replacement efficiency is improved, and the battery bearing device adapts to battery packs of different lengths.

[0015] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the first bearing part includes two first bearing plates arranged at intervals, and at least one of the two first bearing plates is movable back and forth along a direction perpendicular to the moving direction of the first bearing part.

[0016] and / or,

[0017] The second bearing part comprises two second bearing plates arranged at intervals, at least one of which can move back and forth in a direction perpendicular to the moving direction of the second bearing part.

[0018] The first bearing plate is arranged to move in a direction perpendicular to the movement of the first bearing part. When the first bearing part moves in its width direction, the first bearing plate can move in its length direction. Therefore, when the first bearing part is adjusted to adapt to battery packs of different widths, the first bearing plate can be further adjusted to adapt to the length of the battery pack. Similarly, when the first bearing part moves in its width direction, the first bearing plate can move in its length direction, thereby achieving the overall adaptation of the first bearing part to the width and length of the battery pack.

[0019] Similarly, the second bearing plate is arranged to move in a direction perpendicular to the movement of the second bearing part. When the second bearing part moves in its width direction, the second bearing plate can move in its length direction. Therefore, when the second bearing part is adjusted to adapt to battery packs of different widths, the second bearing plate can be further adjusted to adapt to the length of the battery pack. Similarly, when the second bearing part moves in its width direction, the second bearing plate can move in its length direction, thereby achieving the overall adaptation of the second bearing part to the width and length of the battery pack.

[0020] Moreover, whether it is the first bearing plate or the second bearing plate, one of them can be moved alone for quick adjustment of the first bearing plate or the second bearing plate. When the length or width of the battery pack is large, the first bearing plate or the second bearing plate that is not moved can provide force compensation to the side in the non-moving direction, facilitating the positioning and receiving of battery packs of different specifications. Alternatively, both first bearing plates or second bearing plates can be moved simultaneously. When the moving directions of the two first bearing plates or second bearing plates are the same, the connection structure can be simplified and the implementation difficulty can be reduced. When the moving directions of the two first bearing plates or second bearing plates are opposite, simultaneous movement can quickly position them and provide larger range of receiving and positioning for the battery pack, further improving the battery replacement efficiency.

[0021] In addition, when the first bearing plate and the second bearing plate are both movable, the position of the first bearing plate or the second bearing plate can be adjusted individually according to the specifications of the battery pack, or the positions of the first bearing plate and the second bearing plate can be adjusted synchronously, thereby adapting to the specifications of the battery pack under different working conditions and improving the battery replacement efficiency of the device.

[0022] In a preferred implementation of the battery carrying device for vehicle battery replacement, the battery carrying device further comprises a driving mechanism connected to the first carrying part and the second carrying part respectively to drive the first carrying part and the second carrying part to move synchronously.

[0023] The driving mechanism is arranged to drive the first carrying part and the second carrying part to move, which avoids errors caused by manual operation and reduces the labor burden, and is conducive to improving the moving efficiency of the first carrying part and the second carrying part and the mechanization and automation of the battery carrying device. In addition, the synchronous movement of the first carrying part and the second carrying part can accelerate the positioning speed when the carrying device moves, further improving the battery replacement efficiency.

[0024] In a preferred implementation of the battery carrying device for vehicle battery replacement, the driving mechanism comprises a hydraulic cylinder and a first belt assembly, the first belt assembly is connected to the first carrying part and the second carrying part respectively, and the hydraulic cylinder drives the first belt assembly to drive the first carrying part and the second carrying part to move synchronously.

[0025] The hydraulic cylinder and the first belt assembly are arranged as the driving mechanism, which has a simple transmission mode, low component cost, and convenient maintenance. The driving effect of the hydraulic cylinder is stable, and the first belt assembly requires fewer connecting components during transmission, which has a simple connection mode and can ensure the driving stability of the first carrying part and the second carrying part while reducing the processing and assembly difficulty, thereby realizing the adaptation effect of the battery carrying device to different specifications of battery packs.

[0026] In a preferred implementation of the battery carrying device for vehicle battery replacement, the first belt assembly comprises a belt, a fixed roller and a movable roller, the end of the movable roller is connected to the hydraulic cylinder, the two ends of the belt are connected to the first carrying part and the second carrying part respectively, and the belt is folded and sleeved on the movable roller and the fixed roller. The hydraulic cylinder drives the movable roller to move the belt, so that the first carrying part and the second carrying part move in opposite directions or move away from each other.

[0027] The movable roller is arranged to drive the belt to move, and the positioning roller is arranged to limit the belt, thereby realizing the driving movement of the first belt assembly to the first carrying part and the second carrying part. The extension and contraction of the hydraulic cylinder drive the movable roller to have opposite moving directions, so that the belt has opposite moving directions, and the first carrying part and the second carrying part connected to the belt have different moving directions respectively, thereby realizing the opposite movement or away movement of the first carrying part and the second carrying part, and making them close to or away from each other to adapt to different specifications of battery packs.

[0028] In a preferred implementation of the battery carrying device for vehicle battery replacement, the driving mechanism further comprises a linear guide rail, the other end of the movable roller is connected to the linear guide rail, and the hydraulic cylinder drives the movable roller to move along the linear guide rail.

[0029] The straight guide rail is arranged, so that the movable roller moves along the preset straight guide rail path direction, avoids the movable roller from being skewed during the movement to cause the path deviation or the belt twisting, thereby improving the use stability of the driving mechanism, and realizing the stable driving effect of the first bearing part and the second bearing part.

[0030] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the driving structure further comprises a reset coil spring, and the reset coil spring is connected with the outer side of the first bearing part and the second bearing part respectively.

[0031] When the belt hydraulic cylinder is retracted, the movable roller is driven to retreat, thereby driving the belt to retract. During the process, the belt may be loose and cannot be fully tensioned, which causes the movement to be out of position. The reset coil spring is arranged to be connected with the outer side of the first bearing part and the second bearing part respectively, and the first bearing part and the second bearing part are driven to move away from each other, so that the belt is subjected to tension from both sides, the first belt assembly is in a tensioned state, and the first belt assembly is maintained in a good use state, thereby realizing multiple movement operations.

[0032] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the driving mechanism comprises a first driving motor and a second belt assembly, the second belt assembly is connected with the first bearing part and the second bearing part respectively, and the first driving motor drives the second belt assembly to drive the first bearing part and the second bearing part to move synchronously.

[0033] The first driving motor and the second belt assembly are arranged as the driving mechanism, which has a simple transmission mode, low component cost, and convenient maintenance. The driving effect of the first driving motor is stable, and the second belt assembly requires fewer connecting components during transmission and has a simple connection mode. The processing difficulty and assembly difficulty are reduced while the driving stability of the first bearing part and the second bearing part is ensured, thereby realizing the adaptation effect of the battery bearing device to different specifications of battery packs.

[0034] In a preferred implementation manner of the battery bearing device for vehicle battery replacement, the second belt assembly comprises a synchronous pulley in transmission connection with the first driving motor, the synchronous pulley is externally sleeved with a synchronous belt, the synchronous belt is connected with the first bearing part and the second bearing part respectively, and the first driving motor drives the synchronous pulley to move the synchronous belt in forward rotation or reverse rotation, so that the first bearing part and the second bearing part move away from each other or move towards each other.

[0035] The synchronous belt wheel drives the synchronous belt to move, and the synchronous belt wheel has a limiting effect on the synchronous belt, so that the synchronous belt can move in a predetermined direction, and then drive the first bearing part and the second bearing part to move through the connection of the synchronous belt. The forward rotation and reverse rotation of the motor drives the synchronous belt wheel to have opposite rotation directions, so that the synchronous belt has different moving directions, and the first bearing part and the second bearing part connected with the synchronous belt have different moving directions when the first driving motor rotates forward and reversely, realizing the opposite movement or the back-to-back movement of the first bearing part and the second bearing part, so that they are close to or away from each other, changing the distance between them, thereby realizing the adaptive bearing of different specifications of battery packs.

[0036] In a preferred implementation of the battery bearing device for vehicle battery replacement, the synchronous belt includes an upward synchronous belt and a downward synchronous belt in the vertical direction, and the driving mechanism further includes an upper limiting piece connected with the upward synchronous belt and a lower limiting piece connected with the downward synchronous belt. One of the upper limiting piece and the lower limiting piece is connected with the first bearing part, and the other is connected with the second bearing part.

[0037] By setting the upper limiting piece and the lower limiting piece, the upward synchronous belt and the downward synchronous belt are connected with the first bearing part and the second bearing part respectively, thereby driving the first bearing part and the second bearing part to move. It can be understood that the downward synchronous belt is formed by changing the direction after being bent at the synchronous belt wheel from the upward synchronous belt, so the upward synchronous belt and the downward synchronous belt have opposite moving directions, driving the first bearing part and the second bearing part to move reversely, to realize the distance adjustment between the first bearing part and the second bearing part.

[0038] In a preferred implementation of the battery bearing device for vehicle battery replacement, the battery bearing device for vehicle battery replacement includes a bottom plate, and the first bearing part and the second bearing part are located above the bottom plate. The synchronous belt wheel is fixed to the outer side of the bottom plate.

[0039] By fixing the position of the synchronous belt wheel, the synchronous belt wheel located on the outer side of the bottom plate is far away from the first bearing part and the second bearing part located on the top surface of the battery replacement equipment, thereby leaving sufficient margin for the movement of the first bearing part and the second bearing part, further increasing the adaptive range of the battery bearing device.

[0040] In a preferred implementation of the battery bearing device for vehicle battery replacement, the driving mechanism includes a second driving motor and a rotating assembly connected with the second driving motor. The rotating assembly is connected with the first bearing part and the second bearing part respectively. The second driving motor rotates forward or reversely to drive the rotating assembly to drive the first bearing part and the second bearing part to move oppositely or back-to-back.

[0041] The second driving motor and the rotating assembly are arranged as the driving mechanism, the transmission mode is simple, the component cost is low, and the maintenance is convenient.

[0042] In an optimal implementation of the battery carrying device for vehicle battery replacement, the rotating assembly comprises a ball screw in transmission connection with the second driving motor, the ball screw is fixedly connected with the first carrying part and the second carrying part respectively, and the two nuts of the ball screw are arranged in opposite directions.

[0043] In this mode, the ball screw is selected as the transmission assembly to convert rotary motion into linear motion, thereby realizing linear movement of the first carrying part and the second carrying part, which has small friction loss, high transmission efficiency, and the advantage of saving electricity. In addition, the transmission mode of the ball screw has high precision and axial stiffness, which is beneficial to ensure the transmission effect and working stability, so that the first carrying part and the second carrying part realize good movement effect. The ball screw comprises a nut, and the two nuts at the connection positions of the first carrying part and the second carrying part are arranged in opposite directions, so that when the ball screw rotates, the first carrying part and the second carrying part move in opposite directions, the distance between them is changed, and the adaptation carrying of different specifications of battery packs is realized.

[0044] In an optimal implementation of the battery carrying device for vehicle battery replacement, the driving mechanism further comprises a reversing device connected with the second driving motor and the ball screw, and the motor drives the ball screw to rotate through the reversing device.

[0045] The reversing device is arranged to make the ball screw have different rotation directions under the driving of the second driving motor, so that the first carrying part and the second carrying part can realize movement in two opposite directions, so as to realize movement of the first carrying part and the second carrying part in different directions under different conditions, so as to reduce or increase the distance between them, and realize the adaptation carrying of different specifications of battery packs.

[0046] In an optimal implementation of the battery carrying device for vehicle battery replacement, the rotating assembly further comprises a support seat fixed to the first carrying part and the second carrying part respectively, and the end of the ball screw is located in the support seat.

[0047] The support seat is arranged to indirectly connect the ball screw with the first carrying part and the second carrying part, so as to realize stable transmission effect of the ball screw on the first carrying part and the second carrying part, and improve the overall stress stability of the driving mechanism, which is beneficial to maintain the movement stability of the first carrying part and the second carrying part during driving.

[0048] In a preferred implementation of the battery carrying device for vehicle battery swap, the rotating assembly comprises a rotating rod and a connecting arm, the rotating rod is centrally connected with the second driving motor, and the two ends of the rotating rod are respectively provided with the connecting arm, and the connecting arm is respectively connected with the first carrying part and the second carrying part.

[0049] In this implementation, the rotating rod drives the connecting arm to rotate, and in turn drives the first carrying part and the second carrying part connected with the connecting arm to rotate. The rotating rod serves as a driving part to make rotary motion, and the connecting arm connected therewith serves as a driven part to make reciprocating motion, thereby converting the rotary motion into linear motion. The first carrying part and the second carrying part are driven to move linearly by the simple structure, and the distance between the first carrying part and the second carrying part is adjusted to adapt to battery packs of different specifications.

[0050] In a preferred implementation of the battery carrying device for vehicle battery swap, the rotating assembly is located between the first carrying part and the second carrying part.

[0051] By arranging the rotating assembly between the two carrying parts, the connection between the rotating assembly and the first carrying part and the second carrying part can be achieved, and the transmission effect of the rotating assembly can be quickly and stably achieved, and the movement of the first carrying part and the second carrying part can be stably achieved.

[0052] In a preferred implementation of the battery carrying device for vehicle battery swap, the battery carrying device further comprises a guide structure, and the first carrying part and the second carrying part are respectively connected with the guide structure, so that at least one of the first carrying part and the second carrying part moves in a preset direction.

[0053] Through the guide structure, the movement of the first carrying part and the second carrying part is limited, so that the movement path of the first carrying part and the second carrying part is not changed due to deviation of the movement direction, and the first carrying part and the second carrying part can be quickly and accurately moved to the position in the preset direction, thereby improving the movement reliability of the first carrying part and the second carrying part.

[0054] In a preferred implementation of the battery carrying device for vehicle battery swap, the guide structure comprises a guide rail and a slider matched with the guide rail, and the first carrying part and the second carrying part are connected with the slider, and the first carrying part and the second carrying part move along the guide rail through the slider.

[0055] The guide rail and the slider are arranged to connect the first carrying part and the second carrying part, so that the first carrying part and the second carrying part can move along the guide rail through the slider. During the movement of the first carrying part and the second carrying part, the guide rail limits and guides the first carrying part and the second carrying part, so that the first carrying part and the second carrying part can move in the preset direction, and the phenomenon that the first carrying part and the second carrying part cannot smoothly receive the battery pack or are not stably received due to deviation of the movement direction is avoided. In addition, the guide rail and the slider have low cost, are convenient to maintain, require small installation space, and have good use effect.

[0056] The scheme also includes a battery replacement device provided with the battery carrying device for vehicle battery replacement in any of the above implementation manners.

[0057] In a preferred implementation manner of the battery replacement device, the battery replacement device further includes at least two battery trays respectively detachably connected to the top surfaces of the first carrying part and the second carrying part, and the battery trays are arranged in a floating manner relative to the first carrying part or the second carrying part.

[0058] The detachable battery tray facilitates maintenance and replacement, and has low processing difficulty; the floating battery tray facilitates adjustment of the distance between the battery tray and the first carrying part or the second carrying part according to actual working conditions, and facilitates accurate receiving of the battery pack by the battery tray when the battery pack is placed, so that the battery tray is closely attached to the battery pack, avoiding shaking of the battery pack at the battery tray and avoiding placement deviation of the battery pack, thereby keeping the battery replacement process stable and improving the application reliability and the battery replacement efficiency of the battery replacement device.

[0059] In a preferred implementation manner of the battery replacement device, the battery replacement device further includes a battery pack positioning part for positioning the battery pack from both sides in the width direction of the battery pack, and the battery pack positioning part is arranged at the outer periphery of the battery carrying device and is driven to move by the back-and-forth movement of the battery carrying device to adapt to the width of the battery pack.

[0060] The battery pack positioning part limits the position of the battery pack, avoiding position deviation or shaking of the battery pack, thereby ensuring the position stability of the battery pack at the battery carrying device. The battery pack positioning part moves with the battery carrying device, and does not need to be additionally provided with a moving component to adapt to battery packs of different specifications, so that the cooperation and limiting effect of the battery pack positioning part and the battery pack can be achieved, parts are reduced, assembly difficulty is reduced, and the whole battery carrying device has a larger moving space. The battery pack positioning part is arranged at the outer periphery of the battery carrying device, and the battery pack is positioned from the outer periphery of the battery carrying device, without affecting the relative movement between the first carrying part and the second carrying part.

[0061] In addition, since the battery pack positioning part can move with the battery carrying device, the battery pack connected and positioned thereby can move synchronously with the battery pack positioning part, and the battery pack is driven to be locked or unlocked in the positioning state, so that the battery pack is smoothly mounted on or separated from the electric vehicle, which is beneficial to improving the movement stability of the battery pack during locking and unlocking, and ensuring the quick and smooth progress of the battery replacement process.

[0062] In a preferred implementation manner of the battery replacement device, the battery pack positioning part is a plurality of positioning forks fixed to the outer side of the battery carrying device.

[0063] The positioning fork is low in cost and convenient to install. Multiple positioning forks are arranged to position the battery pack from multiple positions, which is beneficial to disperse the stress and further ensure the positioning stability of the battery pack in the battery replacement process, and even if the positioning effect of a certain position fork is poor, it will not affect the overall positioning effect of the battery pack.

[0088] In addition, the battery carrying device 2 is designed in a split manner, and two carrying parts are arranged respectively, which is conducive to reducing the overall weight, reducing the consumption of materials, reducing the cost, facilitating popularization, and facilitating the adaptation and receiving of battery packs of different specifications.

[0089] For example, in the present application, the left side of the figure is the first carrying part 21, and the right side is the second carrying part 22.

[0090] ​In an embodiment, the first bearing part 21 and the second bearing part 22 are arranged in parallel along the width direction of the battery pack, and are respectively arranged movable back and forth along the width direction to adapt to battery packs of different widths.

[0091] In this way, the battery pack of different widths can be adapted. And the first bearing part 21 and the second bearing part 22 are respectively arranged movable, and both of them can be moved simultaneously or one of them can be moved alone to adapt to different installation environments and different operating conditions, and the adjustment mode is selected according to the actual situation to improve the battery replacement efficiency, so that the battery bearing device 2 can adapt to battery packs of different widths.

[0092] In another embodiment, the first bearing part 21 and the second bearing part 22 are arranged in parallel along the length direction of the battery pack, and are respectively arranged movable back and forth along the length direction to adapt to battery packs of different lengths.

[0093] In this way, the battery pack of different lengths can be adapted. And the first bearing part 21 and the second bearing part 22 are respectively arranged movable, and both of them can be moved simultaneously or one of them can be moved alone to adapt to different installation environments and different operating conditions, and the adjustment mode is selected according to the actual situation to improve the battery replacement efficiency, so that the battery bearing device 2 can adapt to battery packs of different lengths.

[0094] In addition, the first bearing part 21 of the present scheme can be moved and adjusted by itself. As shown in Figure 3 In an embodiment, the first bearing part 21 includes two first bearing plates arranged at intervals, and at least one of the two first bearing plates is movable back and forth along a direction perpendicular to the moving direction of the first bearing part 21.

[0095] The first bearing plate is arranged movable along a direction perpendicular to the moving direction of the first bearing part 21, and when the first bearing part 21 moves along its width direction, the first bearing plate can move along its length direction. Therefore, when the first bearing part 21 is adjusted to adapt to battery packs of different widths, the first bearing plate can be further adjusted to adapt to the length of the battery pack. Similarly, when the first bearing part 21 moves along its width direction, the first bearing plate can move along its length direction, so that the first bearing part 21 can adapt to the width and length of the battery pack.

[0096] Similarly, the second bearing part 22 can include two second bearing plates arranged at intervals, and at least one of the two second bearing plates is movable back and forth along a direction perpendicular to the moving direction of the second bearing part 22.

[0097] Similarly, the second bearing plate is arranged to move in the vertical direction relative to the movement of the second bearing part 22, and when the second bearing part 22 moves in the width direction thereof, the second bearing plate can move in the length direction thereof, so that the second bearing part 22 can be adjusted to adapt to battery packs of different widths, and further adjusted to adapt to the length of the battery pack. Similarly, when the second bearing part 22 moves in the width direction thereof, the second bearing plate can move in the length direction thereof, so that the second bearing part 22 can adapt to the width and length of the battery pack.

[0098] And whether it is the first bearing plate or the second bearing plate, one of them can be moved alone, and the first bearing plate or the second bearing plate can be quickly adjusted, and when the length or width of the battery pack is large, the first bearing plate or the second bearing plate that is not moved can provide force compensation to the side in the non-moving direction, facilitating positioning and receiving of battery packs of different specifications. Or move both first bearing plates or second bearing plates at the same time, when the moving directions of the two first bearing plates or second bearing plates are the same, the connection structure can be simplified, and the implementation difficulty can be reduced; when the moving directions of the two first bearing plates or second bearing plates are opposite, simultaneous movement can quickly position them and provide larger range of receiving and positioning for the battery pack, further improving the battery replacement efficiency.

[0099] In addition, when the movable first bearing plate and the second bearing plate are arranged at the same time, the position of the first bearing plate or the second bearing plate can be adjusted alone according to the specification of the battery pack, or the position of the first bearing plate and the second bearing plate can be adjusted synchronously, to adapt to the specification of the battery pack under different working conditions and improve the battery replacement efficiency of the device.

[0100] It should be noted that according to the installation space and the actual use scene, the first bearing plate and the second bearing plate can be provided with multiple ones according to actual needs, so that any one or several first bearing plates or second bearing plates move in the vertical direction relative to the moving direction of the first bearing part 21 or the second bearing part 22, to adapt to battery packs of different specifications and further improve the use range of the device.

[0101] It can be understood that the two or more first bearing plates and second bearing plates in the present scheme are arranged side by side and spaced apart in the horizontal direction, to adapt to battery packs of different specifications through the above-mentioned movement mode.

[0102] As shown in FIG. Figures 1 to 11 In one embodiment of the present scheme, the first bearing part 21 and the second bearing part 22 are driven to move by the driving mechanism 3. The battery bearing device 2 further comprises a driving mechanism 3 connected to the first bearing part 21 and the second bearing part 22 respectively to drive the first bearing part 21 and the second bearing part 22 to move synchronously.

[0103] The drive mechanism 3 moves the first support section 21 and the second support section 22, avoiding errors caused by manual operation, reducing the workload of workers, and improving the moving efficiency of the first support section 21 and the second support section 22, thus enhancing the mechanization and automation of the battery carrier device 2. Furthermore, the synchronous movement of the first support section 21 and the second support section 22 accelerates the positioning speed of the carrier device, further improving battery swapping efficiency.

[0104] It should be noted that the specific structure of the drive mechanism 3 in this solution can be varied, and the following embodiments can be referred to for details:

[0105] Example 1:

[0106] like Figure 1 , Figure 2 As shown, the drive mechanism 3 includes a hydraulic cylinder 31 and a first belt assembly 3301. The first belt assembly 3301 is connected to the first bearing part 21 and the second bearing part 22 respectively. The hydraulic cylinder 31 drives the first belt assembly 3301 to move the first bearing part 21 and the second bearing part 22 synchronously.

[0107] The hydraulic cylinder 31 and the first belt assembly 3301 are set as the driving mechanism 3. The transmission method is simple, the component cost is low, and the maintenance is convenient. The driving effect of the hydraulic cylinder 31 is stable. The first belt assembly 3301 requires fewer connecting parts during transmission and the connection method is simple. While reducing the processing and assembly difficulty, it can ensure the driving stability of the first bearing part 21 and the second bearing part 22, so as to realize the adaptability of the battery bearing device 2 to battery packs of different specifications.

[0108] Furthermore, the first belt assembly 3301 includes a belt 331, a fixed roller 332, and a movable roller 333. The end of the movable roller 333 is connected to the hydraulic cylinder 31. The two ends of the belt 331 are respectively connected to the first bearing part 21 and the second bearing part 22. The belt 331 is bent and sleeved on the movable roller 333 and the fixed roller 332. The hydraulic cylinder 31 drives the movable roller 333 to move the belt 331 so that the first bearing part 21 and the second bearing part 22 move in opposite directions or in opposite directions.

[0109] The movable roller 333 drives the belt 331 to move, while the positioning roller limits the belt 331, thus enabling the first belt assembly 3301 to drive the first support part 21 and the second support part 22 to move. The extension and retraction of the hydraulic cylinder 31 drives the movable roller 333 to move in opposite directions, thereby causing the belt 331 to move in opposite directions. As a result, the first support part 21 and the second support part 22 connected to the belt 331 each have different directions of movement, enabling the first support part 21 and the second support part 22 to move in opposite directions or away from each other, so that they move closer or further apart to adapt to different specifications of battery packs.

[0110] It can be understood that, as shown in Figure 2 The opening direction of the belt 331 formed when the fixed roller 332 and the movable roller 333 are sleeved is opposite, so that the moving directions of the two ends of the belt 331 are different, thereby realizing that the moving directions of the first carrying part 21 and the second carrying part 22 are opposite.

[0111] Preferably, the driving mechanism 3 further comprises a linear guide rail 34, and the other end of the movable roller 333 is connected with the linear guide rail 34, and the hydraulic cylinder 31 drives the movable roller 333 to move along the linear guide rail 34.

[0112] By arranging the linear guide rail 34, the movable roller 333 moves along the preset path direction of the linear guide rail 34, avoiding the path deviation or the belt 331 twisting caused by the skew of the movable roller 333 during the movement, thereby improving the use stability of the driving mechanism 3 and realizing the stable driving effect on the first carrying part 21 and the second carrying part 22.

[0113] Further, the driving structure further comprises a reset coil spring 37, and the reset coil spring 37 is connected with the outer side of the first carrying part 21 and the second carrying part 22 respectively.

[0114] Because the belt 331 is driven to retreat by the contraction of the hydraulic cylinder 31, thereby driving the belt 331 to retract, the belt 331 may be relaxed and not fully tensioned during the process, resulting in that the movement is not in place. The reset coil spring 37 is arranged to be connected with the outer side of the first carrying part 21 and the second carrying part 22 respectively, thereby driving the first carrying part 21 and the second carrying part 22 to move backward, so that the belt 331 is subjected to the tension on both sides, realizing the tension state of the first belt assembly 3301, thereby maintaining the good use state of the first belt assembly 3301, to realize the multiple movement operations.

[0115] In this embodiment, the driving motor 32 and the first belt assembly 3301 are arranged between the first carrying part 21 and the second carrying part 22, thereby reserving more movement space for the first carrying part 21 and the second carrying part 22 on both sides, and being arranged at the middle position. Because the first carrying plate and the second carrying plate are originally designed to be separated, they do not occupy other space when being fixed between the two, thereby providing more arrangement modes for the installation of other components.

[0116] Embodiment 2:

[0117] As shown in Figures 3 to 6 The driving mechanism 3 comprises a first driving motor 3201 and a second belt assembly 3302, the second belt assembly 3302 is connected with the first carrying part 21 and the second carrying part 22 respectively, and the first driving motor 3201 drives the second belt assembly 3302 to drive the first carrying part 21 and the second carrying part 22 to move synchronously.

[0118] The first driving motor 3201 and the second belt assembly 3302 are arranged as the driving mechanism 3, which has simple transmission mode, low component cost, convenient maintenance, stable driving effect of the first driving motor 3201, and less required connecting components and simple connecting mode of the second belt assembly 3302 during transmission, so as to reduce the processing and assembly difficulty while ensuring the driving stability of the first bearing part 21 and the second bearing part 22, and realize the adaptation effect of the battery bearing device 2 to different specifications of battery packs.

[0119] Further, the second belt assembly 3302 includes a synchronous pulley 334 in transmission connection with the first driving motor 3201, the synchronous pulley 334 is externally sleeved with a synchronous belt, the synchronous belt is connected with the first bearing part 21 and the second bearing part 22 respectively, and the first driving motor 3201 drives the synchronous pulley 334 to move the synchronous belt in forward rotation or reverse rotation, so as to move the first bearing part 21 and the second bearing part 22 in opposite directions or in opposite directions.

[0120] The synchronous pulley 334 is arranged to drive the synchronous belt to move, and the synchronous pulley 334 has a limiting effect on the synchronous belt, so that the synchronous belt can move in a preset direction, and then drive the first bearing part 21 and the second bearing part 22 to move through the connection of the synchronous belt. The forward rotation and reverse rotation of the motor drive the synchronous pulley 334 to have opposite rotation directions, so that the synchronous belt has different moving directions, and the first bearing part 21 and the second bearing part 22 connected with the synchronous belt have different moving directions when the first driving motor 3201 rotates forward and reversely, so as to realize the opposite movement or opposite movement of the first bearing part 21 and the second bearing part 22, and make them close to or away from each other, change the distance between them, and thus realize the adaptive bearing of different specifications of battery packs.

[0121] Further, the synchronous belt includes an upward synchronous belt 335a and a downward synchronous belt 335b in the vertical direction, the driving mechanism 3 further includes an upper limiting piece 336 connected with the upward synchronous belt 335a and a lower limiting piece 337 connected with the downward synchronous belt 335b, one of the upper limiting piece 336 and the lower limiting piece 337 is connected with the first bearing part 21, and the other is connected with the second bearing part 22.

[0122] As shown in Figure 6 The upper limiting piece 336 is connected with the second bearing part 22, and the lower limiting piece 337 is connected with the first bearing part 21.

[0123] By setting an upper limit member 336 and a lower limit member 337, the upper synchronous belt 335a and the lower synchronous belt 335b are respectively connected to the first bearing part 21 and the second bearing part 22, thereby driving the first bearing part 21 and the second bearing part 22 to move. It can be understood that the lower synchronous belt 335b is formed by bending the upper synchronous belt 335a at the synchronous pulley 334 and changing its direction. Therefore, the upper synchronous belt 335a and the lower synchronous belt 335b have opposite directions of movement, driving the first bearing part 21 and the second bearing part 22 to move in opposite directions, so as to realize the distance adjustment between the first bearing part 21 and the second bearing part 22.

[0124] Preferably, the battery carrier 2 for vehicle battery swapping includes a base plate 24, a first carrier part 21 and a second carrier part 22 located above the base plate 24, and a timing pulley 334 fixed to the outer side of the base plate 24.

[0125] By fixing the position of the synchronous pulley 334, the distance between the synchronous pulley 334 located on the outer side of the base plate 24 and the first support part 21 and the second support part 22 located on the top surface of the battery swapping device 1 is relatively large, thereby leaving sufficient margin for the movement of the first support part 21 and the second support part 22, and further increasing the adaptability range of the battery support device 2.

[0126] In addition to the two embodiments described above, the transmission component can also be configured as a rotating assembly 35 to convert rotational motion into linear motion, thereby driving the first bearing part 21 and the second bearing part 22 to move.

[0127] like Figures 7 to 11 As shown, the drive mechanism 3 includes a first drive motor 3201 and a rotating component 35 connected to the first drive motor 3201. The rotating component 35 is connected to the first bearing part 21 and the second bearing part 22 respectively. The first drive motor 3201 rotates forward or backward to drive the rotating component 35 to drive the first bearing part 21 and the second bearing part 22 to move in opposite directions or in opposite directions.

[0128] The first drive motor 3201 and the rotating component 35 are set as the drive mechanism 3. The transmission method is simple, the component cost is low, and the maintenance is convenient. The first drive motor 3201 has a stable driving effect. The rotating component 35 can drive the first support part 21 and the second support part 22 connected to it to move by rotating itself. While reducing the processing difficulty and assembly difficulty, it can achieve stable driving movement of the first support part 21 and the second support part 22, so as to realize the adaptability of the battery support device 2 to battery packs of different specifications.

[0129] Example 3:

[0130] like Figures 7 to 9As shown, the rotating assembly 35 comprises a ball screw 351 in transmission connection with the second driving motor 3202, the ball screw 351 is fixedly connected with the first bearing part 21 and the second bearing part 22 respectively, and the two nuts 352 of the ball screw 351 are oppositely arranged.

[0131] In this mode, the ball screw is selected as the transmission assembly to convert the rotary motion into linear motion, thereby realizing the linear movement of the first bearing part 21 and the second bearing part 22, which has small friction loss, high transmission efficiency, and the advantage of saving electricity. In addition, the transmission mode of the ball screw has high precision and axial stiffness, which is beneficial to ensure the transmission effect and working stability, so as to realize good movement effect of the first bearing part 21 and the second bearing part 22. The ball screw 351 comprises a nut 352, which is oppositely arranged at the connection between the first bearing part 21 and the second bearing part 22, so that when the ball screw 351 rotates, the moving directions of the first bearing part 21 and the second bearing part 22 are opposite, the distance between them is changed, and the adaptive bearing of different specifications of battery packs is realized.

[0132] Preferably, the driving mechanism 3 further comprises a reversing gear 36 connected with the second driving motor 3202 and the ball screw 351, and the motor drives the ball screw 351 to rotate through the reversing gear 36.

[0133] The reversing gear 36 is arranged so that the ball screw 351 has different rotating directions under the driving of the second driving motor 3202, so that the first bearing part 21 and the second bearing part 22 can realize movement in two opposite directions, so as to realize movement of the first bearing part 21 and the second bearing part 22 in different directions under different conditions, so as to reduce or increase the distance between them, and realize adaptive bearing of different specifications of battery packs.

[0134] Further, the rotating assembly 35 further comprises a support seat 353 fixed to the first bearing part 21 and the second bearing part 22 respectively, and the end of the ball screw 351 is located in the support seat 353.

[0135] By arranging the support seat 353 to indirectly connect the ball screw 351 with the first bearing part 21 and the second bearing part 22, the stable transmission effect of the ball screw 351 on the first bearing part 21 and the second bearing part 22 is realized, and the overall stress stability of the driving mechanism 3 is improved, which is beneficial to maintain the movement stability of the first bearing part 21 and the second bearing part 22 during driving.

[0136] It can be understood that in the present scheme, the first bearing part 21 and the second bearing part 22 are both provided with a connection and fixing structure as shown in Figure 8 The fixing mode is not limited.

[0137] Embodiment 4:

[0138] As shown in Figure 10 , Figure 11 , the rotating assembly 35 comprises a rotating rod 354 and a connecting arm 355, the rotating rod 354 is centrally connected with the second driving motor 3202, and the two ends of the rotating rod 354 are respectively provided with the connecting arm 355, and the connecting arm 355 is respectively connected with the first bearing part 21 and the second bearing part 22.

[0139] In this implementation, the rotating rod 354 drives the connecting arm 355 to rotate, and in turn drives the first bearing part 21 and the second bearing part 22 connected with the connecting arm 355 to rotate, the rotating rod 354 as the driving part does the rotating motion, and the connecting arm 355 connected therewith as the driven part does the reciprocating motion, converting the rotating motion into linear motion, and through the simple structure, the first bearing part 21 and the second bearing part 22 are driven to realize linear movement, the distance between the first bearing part 21 and the second bearing part 22 is adjusted to adapt to different specifications of the battery pack.

[0140] Further, the rotating assembly 35 is located between the first bearing part 21 and the second bearing part 22.

[0141] By arranging the rotating assembly 35 between the two bearing parts, the connection between the rotating assembly 35 and the first bearing part 21 and the second bearing part 22 is facilitated, so as to quickly and stably realize the transmission effect of the rotating assembly 35 and stably realize the movement of the first bearing part 21 and the second bearing part 22.

[0142] In this embodiment, the second driving motor 3202 is fixed to the bottom plate 24, or the bottom plate 24 is provided with a limiting hole to limit the output end of the second driving motor 3202, so as to keep the relative position of the rotating rod 354 on the bottom plate 24 stable. It can be understood that the first bearing part 21 and the second bearing part 22 are both provided with a connecting and fixing structure as shown in Figure 11 , and the specific fixing mode is not limited.

[0143] As shown in Figure 1 , Figure 3 , Figure 7 , Figure 10 , in order to further ensure the battery replacement stability and efficiency of the battery bearing device 2, the battery bearing device 2 of the present scheme further comprises a guide structure 4, and the first bearing part 21 and the second bearing part 22 are respectively connected with the guide structure 4, so as to make at least one of the first bearing part 21 and the second bearing part 22 move along a predetermined direction.

[0144] The guide structure 4 limits the movement of the first bearing part 21 and the second bearing part 22, avoids the change of the movement path caused by the deviation of the movement direction of the first bearing part 21 and the second bearing part 22, ensures that the first bearing part 21 and the second bearing part 22 can be quickly and accurately moved to the position along the preset direction, and improves the movement reliability of the first bearing part 21 and the second bearing part 22.

[0145] Preferably, the guide structure 4 comprises a guide rail 41 and a sliding block 42 matched with the guide rail 41, and the first bearing part 21 and the second bearing part 22 are connected with the sliding block 42, and the first bearing part 21 and the second bearing part 22 move along the guide rail 41 through the sliding block 42.

[0146] The guide rail 41 and the sliding block 42 are connected with the first bearing part 21 and the second bearing part 22, so that the first bearing part 21 and the second bearing part 22 can move along the guide rail 41 through the sliding block 42. During the movement of the first bearing part 21 and the second bearing part 22, the guide rail 41 limits and guides the two parts, so that the first bearing part 21 and the second bearing part 22 can move along the preset direction, avoiding the phenomenon that the movement direction deviates and causes the battery pack to be unable to be smoothly received or to be stably received. In addition, the guide rail 41 and the sliding block 42 have low cost, are convenient to maintain, require small installation space, and have good use effect.

[0147] It should be noted that the guide rail 41 can be provided in multiple pieces to disperse the stress of the guide rail 41 during the movement of the first bearing part 21 and the second bearing part 22, avoiding the failure of the guide caused by excessive stress. In addition, the multiple guide rails 41 are beneficial to the consistency of the movement speed of the first bearing part 21 and the second bearing part 22 at different positions, thereby further improving the stability during the movement and improving the movement efficiency.

[0148] In addition, as shown in Figure 1 、 Figure 3 、 Figure 7 、 Figure 10 The present scheme also comprises a battery replacement device, and the battery replacement device is provided with the battery bearing device for vehicle battery replacement in any of the above embodiments.

[0149] Further, the battery replacement device 1 further comprises at least two battery trays 23 which are respectively detachably connected to the top surfaces of the first bearing part 21 and the second bearing part 22, and the battery trays 23 are floatingly arranged relative to the first bearing part 21 or the second bearing part 22.

[0150] The detachable battery tray 23 is convenient for maintenance and replacement, and has low processing difficulty; the battery tray 23 can float, so as to facilitate adjustment of the distance between the battery tray 23 and the first bearing part 21 or the second bearing part 22 according to actual working conditions, and facilitate accurate bearing of the battery pack by the battery tray 23 when the battery pack is placed, so that the battery tray 23 is closely attached to the battery pack, the battery pack is prevented from shaking at the battery tray 23, and the battery pack is prevented from being placed offset, so that the battery tray 23 is not stressed unstably in the battery replacement process, and the stable replacement process is maintained, and the application reliability and the replacement efficiency of the battery replacement equipment 1 are improved.

[0151] Further, the battery replacement equipment 1 further comprises a battery pack positioning part for positioning the battery pack from both sides in the width direction of the battery pack, and the battery pack positioning part is arranged on the outer periphery of the battery bearing device 2 and is driven to move by the back-and-forth movement of the battery bearing device 2 to adapt to the width of the battery pack.

[0152] The battery pack positioning part limits the position of the battery pack, so as to prevent the battery pack from being offset or shaken, and thus the position of the battery pack at the battery bearing device 2 is stable. The battery pack positioning part moves with the battery bearing device 2, and does not need to be additionally provided with a moving component to adapt to battery packs of different specifications, so as to realize the cooperation and limiting effect of the battery pack positioning part and the battery pack, reduce the component setting, reduce the assembly difficulty on the one hand, and provide a larger moving space for the entire battery bearing device 2 on the other hand. The battery pack positioning part is arranged on the outer periphery of the battery bearing device 2, and positions the battery pack from the outer periphery of the battery bearing device 2, so as not to affect the relative movement between the first bearing part 21 and the second bearing part 22.

[0153] In addition, since the battery pack positioning part can move with the battery bearing device 2, the battery pack connected and positioned thereby can move synchronously with the battery pack positioning part, and drives the battery pack to be locked or unlocked in the positioning state, so as to stably install or separate the battery pack from the electric vehicle, which is beneficial to improve the movement stability of the battery pack in the locking or unlocking process, and ensure the quick and smooth replacement process.

[0154] Preferably, the battery pack positioning part is a plurality of positioning forks 11 fixed to the outer side of the battery bearing device 2.

[0155] The positioning fork 11 has low cost and is convenient to install. The plurality of positioning forks 11 can position the battery pack from multiple positions, which is beneficial to disperse the stress and further ensure the positioning stability of the battery pack in the replacement process, and even if the positioning effect of the positioning fork 11 at a certain position is poor, the overall positioning effect of the battery pack will not be affected.

[0156] It should be noted that the start and stop of the driving mechanism 3 and the moving distance of the battery carrying device 2 can be remotely controlled through the control system, and the moving distance can be calculated according to the battery pack specifications by those skilled in the art.

[0158] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment mainly describes the difference from other embodiments.

[0159] The above only describes the embodiments of the application and is not intended to limit the application. Those skilled in the art can make various changes and modifications to the application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the application shall be included in the scope of the claims of the application.
