[0048] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0049] It should be noted that with the popularization of new energy vehicles, the battery life of new energy vehicles has become particularly important. Using battery swapping to replace the battery of the vehicle can save the long waiting time required for charging, greatly alleviating the battery life anxiety of new energy vehicles.

[0050] In the related art, battery packs are usually replaced in battery swap stations, which are generally composed of lifting mechanisms, battery swap carts, and stackers. The lifting mechanism is used to lift the battery pack, the battery swap cart is used to transport the battery pack, and the stacker is used to replace the battery pack. Therefore, the replacement, lifting, and transportation of the battery pack require the coordinated actions of various mechanisms. Each mechanism requires a corresponding servo motor drive and completes the corresponding actions under the control of the PLC, which occupies a large space in the battery swap station and has a high cost.

[0051] Based on this, the present invention proposes a battery exchange device 100, which integrates a walking component 2, a lifting component 3 and a conveying component 4, that is, the handling, lifting and conveying replacement functions are integrated into the battery exchange device 100. The integrated design greatly reduces the occupied space, which is beneficial to reduce the space occupied by the battery exchange station and reduce costs.

[0052] The following describes the battery swap device 100 and the battery swap station 200 proposed in the embodiments of the present invention with reference to the accompanying drawings.

[0053] like Figure 1-Figure 10As shown, the battery exchange device 100 according to the first aspect of the embodiment of the present invention includes: a mounting base 1, a walking component 2, a lifting component 3, a conveying component 4 and a locking and unlocking component 9, the walking component 2 is movably arranged on the mounting base 1, the lifting component 3 is arranged on the walking component 2, and the conveying component 4 is arranged on the lifting component 3, the walking component 2 is suitable for driving the lifting component 3 to drive the conveying component 4 to move along the first direction X of the battery exchange device 100, the lifting component 3 is suitable for driving the conveying component 4 to lift and lower along the second direction Y of the battery exchange device 100, so as to move the conveying component 4 to the battery exchange position, wherein the first direction X is perpendicular to the second direction Y, the conveying component 4 is suitable for conveying the battery pack on the battery exchange device 100 to the battery rack or conveying the battery pack on the battery rack to the battery exchange device 100, the locking and unlocking component 9 is movably arranged on the conveying component 4, and the locking and unlocking component 9 is suitable for locking and unlocking the battery pack.

[0054] Specifically, Fig.10 As shown, the battery swap device 100 is applied to a battery swap station 200, and a battery rack is provided in the battery swap station 200. It can be understood that the battery rack has battery slots, and the battery rack has multiple rows, and each row is provided with multiple battery slots in the height direction. Battery packs (charging state or fully charged state) are placed in a part of the battery slots, and another part of the battery slots are set as empty slots, so as to provide cache positions for battery packs to be charged. It can be understood that the battery swap device 100 is communicatively connected with the battery swap station 200. When the battery swap station 200 enters the vehicle to be battery swapped, the battery swap station 200 sends a battery swap instruction to the battery swap device 100, and the battery swap device 100 performs corresponding battery swap operations according to the battery swap instruction.

[0055] Furthermore, if Figure 1 As shown, the battery swap device 100 includes a mounting base 1, a walking component 2, a lifting component 3, a conveying component 4 and a locking and unlocking component 9, wherein the mounting base 1 is fixedly installed on the battery swap station 200, and the installation method includes but is not limited to bolt connection, etc. The walking component 2 is arranged on the mounting base 1, and along the first direction X (i.e., the horizontal direction) of the battery swap device 100, the walking component 2 can move back and forth relative to the mounting base 1. Furthermore, the lifting component 3 is installed on the walking component 2, and the conveying component 4 is installed on the lifting component 3. In this way, the walking component 2 can drive the lifting component 3 and the conveying component 4 to move as a whole along the first direction X, and then In a step, the lifting component 3 can also drive the conveying component 4 to lift and lower along the second direction Y (i.e., the height direction) of the battery exchange device 100. Thus, through the coordinated use of the walking component 2 and the lifting component 3, the position adjustment of the conveying component 4 in the first direction X and the second direction Y can be achieved, so that the conveying component 4 can be moved to the battery exchange position. It can be understood that the battery exchange position is the position where the battery pack needs to be replaced. The battery exchange position can be the position when the battery pack is removed from the vehicle, the position when the battery pack is placed on the battery rack, or the position where the battery pack is taken from the battery rack. No specific restrictions are made here.

[0056] Furthermore, the battery swap device 100 also includes a locking and unlocking component 9, which can be movably arranged on the conveying component 4. The locking and unlocking component 9 is suitable for locking and unlocking the battery pack. The conveying component 4 is used to convey the battery pack on the battery swap device 100 to the battery rack or to convey the battery pack on the battery rack to the battery swap device 100. That is to say, the conveying component 4 can convey the battery pack removed from the vehicle to the battery rack (empty position) of the battery swap station 200, and can also convey the battery pack on the battery rack to the battery swap device 100 to complete subsequent battery swap operations.

[0057] Furthermore, in order to enable those skilled in the art to better understand the present solution, specific examples are provided below for illustration.

[0058] As an embodiment of the present invention, when a vehicle needs to have its battery replaced, the vehicle to be replaced enters the battery pack replacement area of ​​the battery replacement station 200. It should be noted that the battery pack can be located at the bottom of the vehicle, so the battery replacement device 100 needs to be moved to the bottom of the vehicle for battery replacement. The position of the vehicle battery pack is the battery replacement position. When the battery replacement station 200 issues a battery replacement command to the battery replacement device 100, the battery replacement device 100 controls the walking component 2 to move along the first direction X according to the position of the vehicle battery pack, so that the lifting component 3 and the conveying component 4 move to the bottom of the battery pack, and the lifting component 3 drives the conveying component 4 along the second direction Y. The conveying assembly 4 moves upward so that the conveying assembly 4 is in contact with the lower surface of the battery pack. The unlocking assembly 9 can move to a corresponding position relative to the conveying assembly 4 and unlock the battery pack to remove the battery pack from the vehicle. The removed battery pack is placed on the conveying assembly 4. Then the lifting assembly 3 drives the conveying assembly 4 to move downward along the second direction Y to restore the initial height. The walking assembly 2 moves along the first direction X to move the lifting assembly 3 and the conveying assembly 4 to below the empty position of the battery rack. The lifting assembly 3 drives the conveying assembly 4 to move upward along the second direction Y so that the height of the battery pack is at the same level as the empty position. The height is consistent, and the conveying component 4 conveys the battery pack to the empty position of the battery rack. Then the lifting component 3 drives the conveying component 4 to move downward along the second direction Y to restore the initial height, and drives the lifting component 3 and the conveying component 4 to move to the bottom of the battery position with the fully charged battery pack on the battery rack through the walking component 2. The lifting component 3 drives the conveying component 4 to move upward along the second direction Y, so that the height of the conveying member 42 is consistent with the height of the lower surface of the fully charged battery pack. It can be understood that at this time, at least a portion of the conveying component 4 is in contact with the lower surface of the battery pack, so that the conveying component 4 can move the battery rack The battery pack on the vehicle is transported to the battery exchange device 100, and then the lifting component 3 drives the conveying component 4 to move downward along the second direction Y to restore the initial height, and drives the lifting component 3 and the conveying component 4 to move to the bottom of the vehicle through the walking component 2. It can be understood that the position of the conveying component 4 is opposite to the position where the battery pack needs to be installed on the vehicle. Then the lifting component 3 drives the conveying component 4 to move upward along the second direction Y, so that the fully charged battery pack is moved into the vehicle, and the locking and unlocking component 9 on the conveying component 4 is used to lock the battery pack so that the battery pack is fixedly installed on the vehicle, thereby completing the entire battery exchange process. As a result, the battery exchange device 100 integrates the functions of handling, lifting and replacement, and there is no need to specially set up mechanisms such as lifting mechanisms, battery exchange carts and stackers. The integrated design greatly reduces the occupied space, which is conducive to reducing the space occupied by the exchange station and reducing costs.

[0059] According to the battery exchange device 100 of the embodiment of the present invention, the battery exchange device 100 integrates a walking component 2, a lifting component 3 and a conveying component 4, that is, the handling, lifting and conveying replacement functions are integrated into the battery exchange device 100. The integrated design greatly reduces the occupied space, which is beneficial to reduce the space occupied by the battery exchange station and help reduce costs.

[0060] In some embodiments of the present invention, Figure 2 , Figure 4 , Figure 8 and Fig. 9 As shown, the conveying component 4 includes: a first mounting component 41 and a conveying component 42, the first mounting component 41 is arranged on the lifting component 3, the conveying component 42 is movably arranged on the first mounting component 41, the conveying component 42 is used to place the battery pack, and the conveying component 42 drives the battery pack to move to convey the battery pack on the battery exchange device 100 to the battery rack or to convey the battery pack on the battery rack to the battery exchange device 100.

[0061] Specifically, refer to Figure 2 and Figure 4 As shown, the first mounting member 41 of the conveying assembly 4 is fixedly mounted on the lifting assembly 3, and the mounting method includes but is not limited to bolt connection, etc., so that the lifting assembly 3 can drive the conveying assembly 4 to move up and down as a whole in the second direction Y. Further, the first mounting member 41 can be constructed as but not limited to a plate-like structure, and a conveying member 42 is provided on the first mounting member 41. In some embodiments of the present invention, the conveying member 42 can be but not limited to a conveyor belt, a conveyor roller, etc. When the conveying member 42 is constructed as a conveyor belt, the conveyor belt can circulate relative to the first mounting member 41, and the surface of the conveyor belt is used to place the battery pack. When the conveying assembly 4 moves to the battery replacement position, the surface of the conveyor belt is at least partially in contact with the lower surface of the battery pack, and the transmission belt works, and the conveyor belt drives the battery pack to move, so that the battery pack removed from the vehicle can be transferred from the conveyor belt to the battery rack, or the fully charged battery pack on the battery rack is transferred to the conveyor belt, thereby realizing the replacement function of the battery replacement device 100. The overall structure is simple and reliable, and has a large bearing capacity, which meets the transportation requirements of the battery pack.

[0062] It should be noted that the conveying member 42 may also be other parts with conveying functions, and no specific limitation is made here, as long as the conveying and transfer functions can be achieved.

[0063] In some embodiments of the present invention, Figure 2 and 4As shown, the conveying assembly 4 also includes: a first driving member 43, the first driving member 43 is fixedly mounted on the first mounting member 41, and the first driving member 43 is suitable for driving the conveying member 42 to move so as to drive the battery pack to move. Specifically, the first driving member 43 can be constructed as a driving motor or a driving cylinder, which is not specifically limited here. The first driving member 43 is fixedly mounted on the first mounting member 41, and the first driving member 43 is connected to the conveying member 42 by transmission. Optionally, the first driving member 43 can be directly connected to the conveying member 42 by transmission, or indirectly connected to the conveying member 42 by transmission through other intermediate parts. The first driving member 43 is used to drive the conveying member 42 to move. For example, when the first driving member 43 is constructed as a driving motor and the conveying member 42 is constructed as a conveyor belt, the driving motor drives the conveyor belt to move in a circular motion to drive the battery pack to move on the conveyor belt. In this way, the battery pack removed from the vehicle can be transported from the conveyor member 42 to the battery rack, or the fully charged battery pack on the battery rack can be transported to the conveyor belt, and the driving method is simple and reliable, which is conducive to reducing costs.

[0064] In some embodiments of the present invention, Figure 2 and 4 As shown, the conveying assembly 4 further includes: a first transmission member 44, the first transmission member 44 is connected between the first driving member 43 and the conveying member 42, and the first driving member 43 is suitable for driving the first transmission member 44 to drive the conveying member 42 to move. In other words, the first driving member 43 can be connected to the conveying member 42 through the first transmission member 44. For example, when the first driving member 43 is configured as a driving motor and the conveying member 42 is configured as a conveyor belt, the first transmission member 44 can be a chain, and the chain is connected between the driving motor and the conveyor belt, and the movement of the transmission belt is driven by the pulling of the chain. Such a configuration can realize the conveying function of the conveying member 42 on the one hand, and is also conducive to simplifying the transmission structure, thereby helping to reduce space occupancy.

[0065] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, there are multiple conveying members 42, and the multiple conveying members 42 are arranged at intervals along the third direction Z of the battery exchange device 100, and a first transmission member 44 is connected between any two adjacent conveying members 42, wherein the third direction Z is perpendicular to the first direction X and the second direction Y.

[0066] Specifically, a plurality of conveying members 42 may be arranged on the first mounting member 41. For example, the number of conveying members 42 may be 2, 3, 4, 5, 6, or 7, and may be arranged according to actual needs. No specific limitation is given herein. Furthermore, a plurality of conveying members 42 are arranged at intervals along a third direction Z (i.e., the battery pack conveying direction) of the battery exchange device 100. With such an arrangement, a plurality of conveying members 42 may simultaneously convey the battery pack along the third direction Z. Furthermore, a first transmission member 44 is connected between any two adjacent conveying members 42. For example, Figure 2 As shown, the first driving member 43 is constructed as a driving motor, the conveying member 42 is constructed as a conveying roller, and the first transmission member 44 is constructed as a chain. There are 7 conveying rollers. It can be understood that the conveying roller is rotatably arranged on the first mounting member 41, and each conveying roller is provided with a sprocket. The sprockets of any two adjacent conveying rollers are connected by chain transmission, and the driving motor is also connected to the sprocket of the conveying roller closest to the driving motor by a chain. With such an arrangement, when the driving motor is running, each conveying roller can rotate in one direction driven by its own chain. When a battery pack is placed on the conveying roller, a plurality of conveying rollers rotate synchronously to realize the conveying of the battery pack. In this way, the conveying requirements of the battery pack are met, and the structure is simple and reliable. The simultaneous operation of a plurality of conveying rollers is also conducive to improving the stability of the conveying process.

[0067] In some embodiments of the present invention, Figure 1 , Figure 3-Figure 5 As shown, the walking component 2 includes: a second mounting member 21 and a first movable member 22, the second mounting member 21 is used to install the lifting component 3, the first movable member 22 is arranged on the second mounting member 21, the mounting seat 1 has a first guide rail 11 extending along the first direction X, and the first movable member 22 is arranged on the first guide rail 11 and is movable relative to the first guide rail 11.

[0068] Specifically, if Figure 3As shown, the second mounting member 21 is constructed as a plate-like structure, and a lifting component 3 is installed above the second mounting member 21. The first movable member 22 is arranged on the second mounting member 21. The first movable member 22 can be constructed as a walking wheel or a slider. The mounting seat 1 has a first guide rail 11 extending along the first direction X. The number of the first movable members 22 is multiple. For example, when the first movable member 22 is constructed as a walking wheel, the second mounting member 21 is provided with four walking wheels, and the walking wheels can rotate on the first guide rail 11. The walking wheels and the first guide rail 11 move relative to each other to drive the second mounting member 21 to move along the first direction X. When the first movable member 22 is constructed as a slider, the second mounting member 21 can be provided with four sliders, and the slider and the first guide rail 11 slide relative to each other to drive the second mounting member 21 to move along the first direction X. The specific setting is based on actual needs and is not specifically limited here. With such a setting, the walking component 2 can drive the battery pack to move in the first direction X, thereby realizing the transportation function of the battery pack, and the overall structure is relatively simple and reliable, and the transportation process is relatively smooth.

[0069] In some embodiments of the present invention, Figure 5 As shown, the travel assembly 2 further includes: a first position-limiting member 23 , which is fixed to the second mounting member 21 , and is suitable for abutting against and limiting the side wall of the first guide rail 11 and is movable relative to the first guide rail 11 .

[0070] Specifically, the first limiting member 23 is fixedly mounted on the second mounting member 21. The first limiting member 23 can be configured as, but not limited to, a limiting block or a limiting wheel. The number of the first limiting members 23 can be multiple, and can be set according to actual needs. For example, Figure 5 As shown, a limiting wheel is correspondingly arranged on the side walls opposite to the first guide rail 11. When the second mounting member 21 moves relative to the first guide rail 11, the limiting wheel abuts against the side wall of the first guide rail 11 for limiting and is rotatable relative to the side wall of the first guide rail 11. In this way, the second mounting member 21 can be limited from moving in a direction parallel to the first guide rail 11, thereby avoiding deviation of the second mounting member 21 during movement, which is beneficial to improving movement accuracy.

[0071] In some embodiments of the present invention, Figure 1 , Figure 3-Figure 5 As shown, it also includes: a second driving member 5, the second driving member 5 is fixed to the second mounting member 21, and the second driving member 5 is suitable for driving the first moving member 22 to move relative to the first guide rail 11.

[0072] Specifically, the second driving member 5 can be constructed as a driving motor or a driving cylinder, and no specific limitation is made here. The second driving member 5 is fixedly mounted on the second mounting member 21, and the second driving member 5 is transmission connected to the first movable member 22. Optionally, the second driving member 5 can be directly transmission connected to the first movable member 22, or can be indirectly transmission connected to the first movable member 22 through other intermediate parts. For example, when the first movable member 22 is a walking wheel, the second driving member 5 is constructed as a driving motor, and the output shaft of the driving motor is transmission connected to the walking wheel. The driving motor drives the rotation of the walking wheel to realize the movement of the second mounting member 21 in the first direction X. Or, when the first movable member 22 is a sliding block, the second driving member 5 is constructed as a driving cylinder, and the telescopic shaft of the driving cylinder is transmission connected to the sliding block. The sliding block is driven by the driving cylinder to move relative to the first guide rail 11 to realize the movement of the second mounting member 21 in the first direction X. In this way, the driving requirements of the walking component 2 are met, and the structure is simple and reliable, which is beneficial to cost saving.

[0074] Specifically, if Figure 5 As shown, the second transmission member 6 can be constructed as a gear, and the third transmission member 12 can be constructed as a rack, the rack is fixedly mounted on the mounting base 1, and the gear is installed between the rack and the second driving member 5. When the second driving member 5 adopts a driving motor, the output shaft of the driving motor is connected to the gear transmission, and the driving motor drives the gear and the rack to move relative to each other, so that the first moving member 22 moves relative to the first guide rail 11 along the second direction Y, thereby driving the second mounting member 21 to move in the second direction Y. It should be noted that the second transmission member 6 and the third transmission member 12 can also adopt other transmission parts, which will not be given as examples here, as long as they can meet the transmission requirements.

[0075] In some embodiments of the present invention, Figure 1 , Figure 3-Figure 5As shown, it also includes: a first sensor 7, which is fixed to the mounting base 1 and is configured to detect the limit position of the second mounting member 21. In other words, the mounting base 1 is also provided with the first sensor 7, which is used as a limit sensor. When the first sensor 7 detects that the second mounting member 21 moves to the limit position, the first sensor 7 is triggered, and the first sensor 7 can send a limit signal to the second driving member 5, so that the second driving member 5 stops running, and the second mounting member 21 stops moving, thereby preventing the walking component 2 from driving the lifting component 3 and the conveying component 4 to move out of the working area, that is, the limit stop function is realized.

[0076] In some embodiments of the present invention, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the lifting component 3 includes: a third mounting member 31, the conveying component 4 is arranged on the third mounting member 31, the third mounting member 31 is arranged on the second mounting member 21, and the third mounting member 31 can be lifted relative to the second mounting member 21 along the second direction Y. Specifically, the third mounting member 31 of the lifting component 3 can be constructed as a plate-like structure, the third mounting member 31 is installed on the second mounting member 21 of the walking component 2, the third mounting member 31 is located between the first mounting member 41 of the conveying component 4 and the second mounting member 21 of the walking component 2, the first mounting member 41 can be directly installed on the third mounting member 31, and can also be indirectly installed on the third mounting member 31 through other parts, for example, the first mounting member 41 is installed on the third mounting member 31 through a shock-absorbing elastic member, and further, the third mounting member 31 can be lifted relative to the second mounting member 21 along the second direction Y, so as to meet the adjustment of the conveying component 4 in the height direction.

[0077] In some embodiments of the present invention, Figure 6 As shown, the lifting assembly 3 further includes: a third driving member 32 , which is fixed to the second mounting member 21 and is suitable for driving the third mounting member 31 to rise and fall along the second direction Y relative to the second mounting member 21 .

[0078] Specifically, the third driving member 32 can be constructed as a driving motor or a driving cylinder, which is not specifically limited here. The third driving member 32 is fixedly mounted on the second mounting member 21, and the third driving member 32 is transmission-connected to the third mounting member 31. Optionally, the third driving member 32 can be directly transmission-connected to the third mounting member 31, or can be indirectly transmission-connected to the third mounting member 31 through other intermediate parts. The third driving member 32 is used to drive the third mounting member 31 to rise and fall. For example, when the third driving member 32 uses a driving cylinder, the telescopic member of the driving cylinder is connected to the third mounting member 31, and the telescopic member of the driving cylinder can be telescoped up and down along the second direction Y, thereby meeting the height adjustment requirements of the third mounting member 31, and then meeting the height adjustment requirements of the conveying component 4, and the driving method is simple and reliable, which is conducive to reducing costs.

[0079] In some embodiments of the present invention, Figure 6 As shown, the lifting assembly 3 also includes: a scissor fork 33, a second guide rail 34 and a third guide rail 35.

One side of the scissor fork 33 is hinged to the second mounting member 21 and the third mounting member 31 respectively, and the other side of the scissor fork 33 is slidably connected to the second guide rail 34 and the third guide rail 35 respectively. The third driving member 32 is suitable for driving the other side of the scissor fork 33 to slide.

[0080] Specifically, a scissor fork 33 is installed between the second mounting member 21 and the third mounting member 31. Figure 6 As shown, the upper part of one side of the scissors fork 33 is hinged to the third mounting member 31, the lower part of one side of the scissors fork 33 is hinged to the second mounting member 21, the upper part of the other side of the scissors fork 33 is slidably connected to the third guide rail 35, the lower part of the other side of the scissors fork 33 is slidably connected to the second guide rail 34, and the third driving member 32 is transmission-connected to the lower part of the other side of the scissors fork 33. For example, when the third driving member 32 uses a driving cylinder, the telescopic member of the driving cylinder is connected to the lower part of the other side of the scissors fork 33, and the driving cylinder drives the telescopic member to extend and retract so that the lower part of the other side of the scissors fork 33 slides along the second guide rail 34. According to the characteristics of the structure of the scissors fork 33 itself, the scissors fork 33 can be opened or closed, thereby realizing the height adjustment of the third mounting member 31. It should be noted that the scissors fork 33 is an existing well-known technology and will not be described here.

[0081] In some embodiments of the present invention, Figure 6As shown, the scissor fork 33 includes a first scissor fork 331 and a second scissor fork 332 arranged in parallel with each other. Specifically, the scissor fork 33 includes two first scissor forks 331 and a second scissor fork 332 arranged in parallel with each other, the upper part of one side of the first scissor fork 331 is hinged to the third mounting member 31, the lower part of one side of the first scissor fork 331 is hinged to the second mounting member 21, the upper part of the other side of the first scissor fork 331 is slidably connected to the third guide rail 35, and the lower part of the other side of the first scissor fork 331 is slidably connected to the second guide rail 34, similarly, the upper part of one side of the second scissor fork 332 is hinged to the third mounting member 31, the lower part of one side of the second scissor fork 332 is hinged to the second mounting member 21, the upper part of the other side of the second scissor fork 332 is slidably connected to the third guide rail 35, and the lower part of the other side of the second scissor fork 332 is slidably connected to the second guide rail 34, so that by setting the first scissor fork 331 and the second scissor fork 332, it is beneficial to improve the stability of the third mounting member 31 during lifting and lowering adjustment.

[0082] In some embodiments of the present invention, Figure 6 As shown, the first scissor fork 331 and the second scissor fork 332 both include a first support member 3311 and a second support member 3312, and the first support member 3311 and the second support member 3312 are hinged via a hinge shaft 36. In other words, the first scissor fork 331 and the second scissor fork 332 both include a first support member 3311 and a second support member 3312, and the first support member 3311 and the second support member 3312 are hinged via a hinge shaft 36. By adjusting the opening angle of the first support member 3311 and the second support member 3312, the height adjustment of the third mounting member 31 is achieved, and the adjustment method is simple and reliable.

[0083] In some embodiments of the present invention, Figure 6 As shown, the hinge shaft 36 of the first scissor fork 331 is connected to the hinge shaft 36 of the second scissor fork 332 through the first connecting rod 37. In other words, the first connecting rod 37 is arranged between the hinge shaft 36 of the first scissor fork 331 and the hinge shaft 36 of the second scissor fork 332, and the first connecting rod 37 can rotate relative to the hinge shaft 36 of the first scissor fork 331 and the hinge shaft 36 of the second scissor fork 332. In this way, by providing the first connecting rod 37, it is helpful to improve the strength of the first scissor fork 331 and the second scissor fork 332, and it is helpful to further improve the stability of the third mounting member 31 during the lifting and lowering adjustment.

[0084] In some embodiments of the present invention, Figure 6 and Figure 7As shown, one end of the first support member 3311 is hinged to the second mounting member 21, and the other end of the first support member 3311 is slidably connected to the third guide rail 35 through the first slider 38; one end of the second support member 3312 is hinged to the third mounting member 31, and the other end of the second support member 3312 is slidably connected to the second guide rail 34 through the second slider 39. Specifically, refer to Figure 6 As shown, one end of the first support member 3311 of the first scissors fork 331 and the second scissors fork 332 is hinged to the second mounting member 21, the other end of the first support member 3311 of the first scissors fork 331 and the second scissors fork 332 is slidably connected to the third guide rail 35 through the first slider 38, one end of the second support member 3312 of the first scissors fork 331 and the second scissors fork 332 is hinged to the third mounting member 31, the other end of the second support member 3312 of the first scissors fork 331 and the second scissors fork 332 is slidably connected to the second guide rail 34 through the second slider 39, and further, the third drive The movable member 32 is used to drive the second slider 39 to slide along the second guide rail 34. For example, when the third driving member 32 uses a driving cylinder, the telescopic member of the driving cylinder is connected to the second slider 39. The driving cylinder drives the telescopic member to extend and retract to drive the second slider 39 to slide along the second guide rail 34. At the same time, the first slider 38 will also move along the third guide rail 35. Through the cooperation of the first slider 38 and the second slider 39, the first support member 3311 and the second support member 3312 of the first scissors fork 331 and the second scissors fork 332 are opened or closed, thereby realizing the lifting and lowering control of the third mounting member 31.

[0085] In some embodiments of the present invention, Figure 6 As shown, the lifting assembly 3 also includes: a fourth transmission member 310 and a fifth transmission member 311. The fourth transmission member 310 is fixedly connected to the second slider 39, the fourth transmission member 310 is arranged on the second guide rail 34 and can slide relative to the second guide rail 34, and the fifth transmission member 311 is connected to the third driving member 32 and can be movably arranged on the fourth transmission member 310, so that the third driving member 32 drives the fifth transmission member 311 to drive the fourth transmission member 310 to slide relative to the second guide rail 34. Specifically, the fifth transmission member 311 is constructed as a lead screw, the fourth transmission member 310 is provided with a threaded hole for cooperating with the lead screw, the lead screw is passed through the threaded hole, the third driving member 32 is constructed as a driving motor, the output shaft of the driving motor is connected to the lead screw, the driving motor drives the lead screw to rotate, and the fourth transmission member 310 slides along the second guide rail 34 under the cooperation of the lead screw and the threaded hole. The fourth transmission member 310 is fixedly connected to the second slider 39, thereby driving the second slider 39 to slide along the second guide rail 34, thereby making the first support member 3311 and the second support member 3312 of the first scissors fork 331 and the second scissors fork 332 open or close, thereby realizing the lifting and lowering control of the third mounting member 31.

[0086] In some embodiments of the present invention, Figure 6 As shown, the fourth transmission member 310 has a first lifting guide portion 3101, and the first connecting rod 37 is provided with a first guide wheel 371 which is assembled with the first lifting guide portion 3101, and the third mounting member 31 is lifted and lowered relative to the second mounting member 21 through the guiding cooperation between the first lifting guide portion 3101 and the first guide wheel 371. That is to say, the first lifting guide portion 3101 of the fourth transmission member 310 cooperates with the first guide wheel 371 of the first connecting rod 37, and in the initial stage when the third driving member 32 drives the fourth transmission member 310 to slide along the second guide rail 34, the first lifting guide portion 3101 and the first guide wheel 371 slide relative to each other, so that when the third driving member 32 drives the fourth transmission member 310 to move, the first lifting guide portion 3101 can lift the first guide wheel 371, that is, the first lifting guide portion 3101 has a certain supporting effect on the first guide wheel 371, which is beneficial to improve the stability of the third mounting plate when it rises in the initial stage. When the first guide wheel 371 is separated from the first lifting guide portion 3101, the fourth transmission member 310 drives the lower end of the scissors fork 33 to move forward, and continues to drive the third mounting plate to rise.

[0087] In some embodiments of the present invention, Figure 6 As shown, the second sensor 8 is also included, and the second sensor 8 is fixedly mounted on the second mounting member 21, and the second sensor 8 is configured to detect the limit position of the second slider 39. That is to say, the second sensor 8 is also arranged on the second mounting member 21, and the first sensor 7 is used as a limit sensor. When the second sensor 8 detects that the second slider 39 moves to the limit position, the second sensor 8 is triggered, and the second sensor 8 can send a limit signal to the third driving member 32, and the third driving member 32 stops running, so that the third mounting member 31 stops moving, thereby realizing the descending mechanical protection of the third mounting member 31 and preventing the third mounting member 31 from descending to the bottom.

[0088] In some embodiments of the present invention, Figure 7 and Figure 8 As shown, the locking and unlocking assembly 9 can be movably arranged on the first mounting member 41, and the locking and unlocking assembly 9 has a first position and a second position relative to the first mounting member 41. When the locking and unlocking assembly 9 is in the first position, the locking and unlocking assembly 9 is suitable for locking or unlocking the battery pack to install or remove the battery pack, and the first mounting member 41 has a mounting surface close to the battery pack. When the locking and unlocking assembly 9 is in the second position, the locking and unlocking assembly 9 is located on the side of the mounting surface away from the battery pack.

[0089] Specifically, if Figure 8 As shown, the battery exchange device 100 also includes a locking and unlocking assembly 9, wherein the first mounting member 41 of the locking and unlocking assembly 9 is movable so that the locking and unlocking assembly 9 can move to a first position and a second position relative to the first mounting member 41. Optionally, the movement mode includes but is not limited to translation, etc.

[0090] As a specific example, when the battery swap device 100 needs to replace the battery pack on the vehicle, the battery swap device 100 moves the conveying component 4 to the battery swap position through the cooperation of the walking component 2 and the lifting component 3, that is, the conveying component 4 moves to the lower side of the battery pack. At this time, the locking and unlocking component 9 is in the second position, and the locking and unlocking component 9 is located on the side of the mounting surface away from the battery pack. After the battery pack is docked with the conveying component 4, that is, the conveying component 4 is in contact with the lower surface of the battery pack (the mounting surface of the battery pack), the battery pack needs to be locked by the locking and unlocking component 9. Specifically, the locking and unlocking component 9 is controlled to move to the first position. It should be noted that when the locking and unlocking component 9 is in the first position, part of the locking and unlocking component 9 The structure is assembled in cooperation with the locking part of the battery pack, and the battery pack is locked by driving the locking and unlocking component 9. Furthermore, when the disassembled battery pack needs to be placed in the empty compartment of the battery rack, the height of the battery pack is made consistent with the height of the empty compartment, and then the locking and unlocking component 9 is controlled to unlock the battery pack and move it to the second position to avoid interference during the battery pack transportation process. When the fully charged battery pack needs to be reinstalled on the vehicle, the locking and unlocking component 9 repeats the above steps, which will not be repeated here. In this way, during the battery pack replacement process, the battery pack can be locked by the locking and unlocking component 9 to prevent the battery pack from falling, thereby avoiding bumps during the battery pack transfer process, which is beneficial to improving the safety performance of the battery pack.

[0091] In some embodiments of the present invention, Figure 8 As shown, along the second direction Y, the locking and unlocking assembly 9 is movable relative to the first mounting member 41 so that the locking and unlocking assembly 9 moves to the first position or the second position.

[0092] Specifically, the locking and unlocking assembly 9 can be raised and lowered along the second direction Y (i.e., the height direction) relative to the first mounting member 41. Before replacing the battery pack, the battery exchange device 100 controls the locking and unlocking assembly 9 to be located in the second position, that is, the locking and unlocking assembly 9 is controlled to be located on the side of the mounting surface away from the battery pack. After the battery pack is docked with the conveying assembly 4, that is, the conveying assembly 4 is in contact with the lower surface of the battery pack, the locking and unlocking assembly 9 is controlled to move from the second position to the first position along the second direction Y (i.e., the height direction), so that part of the structure of the locking and unlocking assembly 9 is assembled with the locking part of the battery pack. Such a configuration can ensure the vertical movement of the locking and unlocking assembly 9, and ensure that the locking and unlocking assembly 9 can face the locking part of the battery pack to lock and unlock it, which is beneficial to improve the locking effect of the battery pack and further improve the safety performance of the battery pack.

[0093] In some embodiments of the present invention, Figure 8As shown, the locking and unlocking assembly 9 includes: a locking and unlocking mechanism 91 and a lifting mechanism 92. The locking and unlocking mechanism 91 is fixed to the lifting mechanism 92, and the first mounting member 41 is provided with a first avoidance hole for cooperating with the locking and unlocking mechanism 91. The lifting mechanism 92 is arranged on the first mounting member 41, and the lifting mechanism 92 is movable relative to the first mounting member 41 along the second direction Y so that the locking and unlocking mechanism 91 passes through the first avoidance hole and moves to the first position or the second position.

[0094] Specifically, the locking and unlocking assembly 9 includes a locking and unlocking mechanism 91 and a lifting mechanism 92, wherein the locking and unlocking mechanism 91 can be constructed as a locking motor, and the locking motor is vertically fixedly installed on the lifting mechanism 92, and the fixed installation method includes but is not limited to bolt connection. The first mounting member 41 is provided with a first avoidance hole, and the first avoidance hole corresponds to the corresponding locking and unlocking mechanism 91, so that the locking and unlocking mechanism 91 can extend from or retract into the corresponding first avoidance hole. Furthermore, the lifting mechanism 92 can move relative to the first mounting member 41 along the second direction Y.

[0095] As a specific example, before replacing the battery pack, the battery exchange device 100 controls the locking and unlocking mechanism 91 to be located in the second position, that is, controls the lifting mechanism 92 to move so that the locking and unlocking mechanism 91 is retracted into the first avoidance hole. After the battery pack is docked with the conveying assembly 4, that is, the conveying assembly 4 is in contact with the lower surface of the battery pack, the lifting mechanism 92 is driven to move upward along the second direction Y, so that the locking and unlocking mechanism 91 extends out of the first avoidance hole and extends into the locking portion of the battery pack, so that the locking and unlocking mechanism 91 moves to the first position to cooperate with the locking portion of the battery pack for assembly, and controls the locking and unlocking mechanism 91 to lock the battery pack to fix the battery pack; further, when the disassembled battery pack needs to be placed in the empty compartment of the battery rack, the locking and unlocking mechanism 91 is controlled to unlock the battery pack, and the lifting mechanism 92 is driven to move downward along the second direction Y, so that the locking and unlocking mechanism 91 is retracted into the first avoidance hole again, that is, the locking and unlocking mechanism 91 is controlled to be located on the side of the installation surface away from the battery pack. With such arrangement, the lifting and unlocking of the locking and unlocking assembly 9 is achieved through the coordinated use of the locking and unlocking mechanism 91 and the lifting and unlocking mechanism 92. The structure is simple and reliable, which is beneficial to improving the battery swapping efficiency of the battery swapping device 100.

[0096] In some embodiments of the present invention, Figure 8 As shown, the lifting structure includes: a lifting member 921, the lifting member 921 is arranged on the first mounting member 41 and is located on the side of the first mounting member 41 away from the battery pack, the locking and unlocking mechanism 91 is fixedly arranged on the lifting member 921, and the lifting member 921 is movable relative to the first mounting member 41 along the second direction Y so that the locking and unlocking mechanism 91 moves to the first position or the second position. Specifically, the lifting member 921 can be constructed as a lifting plate, and the locking and unlocking mechanism 91 is vertically fixedly installed on the lifting plate. The lifting and lowering movement of the lifting plate in the second direction Y is controlled to realize the lifting and lowering of the locking and unlocking mechanism 91. The structure is simple and reliable, and the cost is low.

[0097] In some embodiments of the present invention, Figure 8 As shown, the lifting structure also includes: a second movable member 922, the second movable member 922 is movably arranged on the lifting member 921, the second movable member 922 has a first inclined plane driving part 9222, the first mounting member 41 is provided with a first driving wheel 411 assembled with the first inclined plane driving part 9222, the first driving wheel 411 is slidable relative to the first inclined plane driving part 9222 so that the second movable member 922 drives the lifting member 921 to move along the second direction Y.

[0098] Specifically, the second moving member 922 is configured as a moving plate, and the second moving member 922 is movably arranged on the lifting member 921 and is located on a side of the lifting member 921 away from the first mounting member 41, that is, the second moving member 922 is arranged on the lower side of the lifting member 921, and the second moving member 922 has a first inclined plane driving portion 9222, and the first mounting member 41 is provided with a first driving wheel 411 that is assembled with the first inclined plane driving portion 9222. Through the cooperative sliding of the first inclined plane driving portion 9222 and the first driving wheel 411, the second moving member 9222 can be moved. The second movable member 922 moves relative to the lifting member 921, and under the interaction of the first inclined plane driving part 9222 and the first driving wheel 411, the relative movement of the second movable member 922 relative to the lifting member 921 can be converted into the relative lifting movement of the first driving wheel 411 and the first inclined plane driving part 9222, that is, the lifting member 921 is lifted and lowered along the second direction Y through the driving cooperation between the first inclined plane driving part 9222 and the first driving wheel 411, and the above structure is simple and reliable, which ensures the reliability of the movement of the lifting member 921.

[0099] In some embodiments of the present invention, Figure 8 As shown, the second moving member 922 has a first guide portion 9221, and the lifting member 921 is provided with a second guide portion 9211 that is assembled with the first guide portion 9221. The second moving member 922 is moved relative to the lifting member 921 through the guiding cooperation of the first guide portion 9221 and the second guide portion 9211. Specifically, one of the first guide portion 9221 and the second guide portion 9211 can be set as a slider, and the other can be set as a guide rail. Through the guiding cooperation of the slider and the guide rail, the second moving member 922 is moved relative to the lifting member 921. This is conducive to improving the stability of the second moving member 922 and the lifting member 921 during the relative movement, thereby improving the stability of the lifting movement of the lifting member 921.

[0100] In some embodiments of the present invention, Figure 8As shown, the first mounting member 41 has a third guide portion 412, and the lifting member 921 is provided with a fourth guide portion 9212 assembled with the third guide portion 412, so that the lifting member 921 can move relative to the first mounting member 41 along the second direction Y through the guiding cooperation between the third guide portion 412 and the fourth guide portion 9212.

[0101] Specifically, the first mounting member 41 further includes a third guide portion 412, and the lifting member 921 is provided with a fourth guide portion 9212 which is assembled with the third guide portion 412. In the guiding cooperation between the third guide portion 412 and the fourth guide portion 9212, the lifting member 921 moves relative to the first mounting member 41 along the second direction Y. Further, one of the third guide portion 412 and the fourth guide portion 9212 is a guide pin, and the other of the third guide portion 412 and the fourth guide portion 9212 is a guide sleeve. The guide pin is slidably provided on the guide sleeve, and both the guide pin and the guide sleeve extend along the second direction Y. If the third guide portion 412 is provided as a guide pin, the fourth guide portion 9212 is provided as a guide sleeve, and the third guide portion 412 is provided as a guide sleeve, then the fourth guide portion 9212 is provided as a guide pin, and the guide pin can slide along the guide sleeve in the second direction Y. Therefore, by using the third guide part 412 and the fourth guide part 9212 in coordination, it is possible to ensure that the lifting member 921 moves smoothly in the second direction Y, avoiding directional deviation during the movement, and the guide pin and the guide sleeve have a simple structure and are easy to assemble.

Figure 8 As shown, the fourth driving member 93 can be constructed as a driving motor, which is fixedly mounted on the lower surface of the lifting member 921 and fixedly connected to the first guide portion 9221. The driving motor is used for the first guide portion 9221 to make a linear motion relative to the second guide portion 9211. The driving motor drives the first guide portion 9221 to move relative to the second guide portion 9211, so that the first inclined surface driving portion 9222 and the first driving wheel 411 slide relative to each other, and then the first inclined surface driving portion 9222 makes a lifting motion relative to the first mounting member 41 along the second direction Y, thereby realizing automatic lifting control of the lifting member 921 and improving the automation rate of the battery exchange device 100.

[0103] In some embodiments of the present invention, Figure 8As shown, the locking and unlocking assembly 9 further includes: a first positioning member 94, the first positioning member 94 is fixedly mounted on the lifting member 921, the first mounting member 41 is provided with a second avoidance hole opposite to the first positioning member 94, when the locking and unlocking assembly 9 is in the first position, the first positioning member 94 passes through the second avoidance hole and extends into the positioning hole of the battery pack, when the locking and unlocking assembly 9 is in the second position, the first positioning member 94 is located on the side of the mounting surface away from the battery pack. Specifically, as Figure 8 As shown, the first positioning member 94 can be constructed as a positioning pin, and the first positioning member 94 is fixedly mounted on the lifting member 921. Furthermore, the first mounting member 41 is provided with a second avoidance hole, and the first positioning member 94 is arranged corresponding to the second avoidance hole.

When the sixth sensor 50 detects the battery pack, the sixth sensor 50 is triggered, and the sixth sensor 50 can send a signal to the first driving member 43, so that the first driving member 43 stops running, and the conveying member 42 stops conveying the battery pack.

[0110] To achieve the above purpose, if Fig.10 As shown, the second embodiment of the present invention proposes a battery swap station 200, which is characterized by comprising:

[0111] A shell 201, a battery rack and a battery exchange device 100, wherein a charging space is formed in the shell 201, and the battery rack is fixed in the charging space. The battery rack is used to place a battery pack. The battery exchange device 100 is the battery exchange device 100 in the first aspect embodiment. The battery exchange device 100 is fixed in the shell 201, and the battery exchange device 100 is suitable for driving the conveying component 4 to move to the battery exchange position, so that the conveying component 4 conveys the battery pack on the battery exchange device 100 to the battery rack or conveys the battery pack on the battery rack to the battery exchange device 100.

[0112] Specifically, the charging space within the battery swap station 200 is provided with a battery rack, which is used to place battery packs. It can be understood that the battery rack has battery slots, and the battery rack has multiple rows, each row is provided with multiple battery slots in the height direction, and battery packs (in charging state or fully charged state) are placed in a portion of the battery slots, and another portion of the battery slots is set as empty slots, thereby providing cache positions for battery packs to be charged.

[0113] Furthermore, the battery swap device 100 is fixed to the housing 201, and the battery swap device 100 is suitable for driving the conveying assembly 4 to move to the battery swap position. It can be understood that the battery swap device 100 is communicatively connected with the battery swap station 200. When the battery swap station 200 enters the vehicle to be battery swapped, the battery swap station 200 sends a battery swap instruction to the battery swap device 100, and the battery swap device 100 performs the corresponding battery swap operation according to the battery swap instruction. It should be noted that the battery swap position is the position where the battery pack needs to be replaced. The battery swap position can be the position when the battery pack is removed from the vehicle, or the position when the battery pack is placed on the battery rack, or the position where the battery pack is taken from the battery rack. No specific restrictions are made here. In other words, the battery swap device 100 can be moved into the charging space, or it can be moved out of the charging space and the battery pack on the vehicle can be removed. Further, referring to the battery swap device 100 in the embodiment of the first aspect, the battery swap device 100 also includes a locking and unlocking component 9, which can be movably arranged on the conveying component 4, and the locking and unlocking component 9 is suitable for locking and unlocking the battery pack. The conveying component 4 is used to convey the battery pack on the battery swap device 100 to the battery rack or to convey the battery pack on the battery rack to the battery swap device 100. That is to say, the conveying component 4 can convey the battery pack removed from the vehicle to the battery rack (empty position) of the battery swap station 200, and can also convey the battery pack on the battery rack to the battery swap device 100 to complete subsequent battery swap operations.

[0114] Furthermore, in order to enable those skilled in the art to better understand the present solution, specific examples are provided below for illustration.

[0115] As an embodiment of the present invention, when a vehicle needs to have its battery replaced, the vehicle to be replaced enters the battery pack replacement area of ​​the battery replacement station 200. It should be noted that the battery pack can be located at the bottom of the vehicle, so the battery replacement device 100 needs to be moved to the bottom of the vehicle for battery replacement. The position of the vehicle battery pack is the battery replacement position. When the battery replacement station 200 issues a battery replacement command to the battery replacement device 100, the battery replacement device 100 controls the walking component 2 to move along the first direction X according to the position of the vehicle battery pack, so that the lifting component 3 and the conveying component 4 move to the bottom of the battery pack, and the lifting component 3 drives the conveying component 4 along the second direction Y. The conveying assembly 4 moves upward so that the conveying assembly 4 is in contact with the lower surface of the battery pack. The unlocking assembly 9 can move to a corresponding position relative to the conveying assembly 4 and unlock the battery pack to remove the battery pack from the vehicle. The removed battery pack is placed on the conveying assembly 4. Then the lifting assembly 3 drives the conveying assembly 4 to move downward along the second direction Y to restore the initial height. The walking assembly 2 moves along the first direction X to move the lifting assembly 3 and the conveying assembly 4 to below the empty position of the battery rack. The lifting assembly 3 drives the conveying assembly 4 to move upward along the second direction Y so that the height of the battery pack is at the same level as the empty position. The height is consistent, and the conveying component 4 conveys the battery pack to the empty position of the battery rack. Then the lifting component 3 drives the conveying component 4 to move downward along the second direction Y to restore the initial height, and drives the lifting component 3 and the conveying component 4 to move to the bottom of the battery position with the fully charged battery pack on the battery rack through the walking component 2. The lifting component 3 drives the conveying component 4 to move upward along the second direction Y, so that the height of the conveying member 42 is consistent with the height of the lower surface of the fully charged battery pack. It can be understood that at this time, at least a portion of the conveying component 4 is in contact with the lower surface of the battery pack, so that the conveying component 4 can move the battery rack The battery pack on the vehicle is transported to the battery exchange device 100, and then the lifting component 3 drives the conveying component 4 to move downward along the second direction Y to restore the initial height, and drives the lifting component 3 and the conveying component 4 to move to the bottom of the vehicle through the walking component 2. It can be understood that the position of the conveying component 4 is opposite to the position where the battery pack needs to be installed on the vehicle. Then the lifting component 3 drives the conveying component 4 to move upward along the second direction Y, so that the fully charged battery pack is moved into the vehicle, and the locking and unlocking component 9 on the conveying component 4 is used to lock the battery pack so that the battery pack is fixedly installed on the vehicle, thereby completing the entire battery exchange process. As a result, the battery exchange device 100 integrates the functions of handling, lifting and replacement, and there is no need to specially set up mechanisms such as lifting mechanisms, battery exchange carts and stackers. The integrated design greatly reduces the occupied space, which is conducive to reducing the space occupied by the exchange station and reducing costs.
