The battery exchange unit 7 is a prior art. The existing battery exchange unit 7 includes a lifting platform, and the lifting platform is generally a scissor-type lifting platform. The lifting platform is provided with a battery exchange component for installing and removing the battery. As a specific implementation method, the battery exchange unit 7 described in this embodiment can adopt the battery exchange unit 7 in the prior art, and the specific structure of the battery exchange unit 7 will not be described in detail here.

[0070] The battery rack 4 may be an existing battery rack 4 with a charging function, and the specific structure of the battery rack 4 will not be described in detail here.

[0071] like Figure 2 As shown, the slide 1 includes a base frame. The base frame includes crossbeams 111 respectively located on the front and rear sides of the battery exchange unit 7 and extending in the transverse direction. A first bracket 12 is slidably provided on both crossbeams 111, and when the battery exchange unit 7 is lowered to the lowest position, the upper side of the first bracket 12 is located above the battery exchange unit 7. The first bracket 12 can move left and right along the crossbeam 111, and the slide 1 also includes a first driving mechanism for driving the first bracket 12 to move left and right.

[0074] As a specific implementation method, Figure 3 As shown, the first transmission belt 135 described in this embodiment is an open structure, and the two ends of the first transmission belt 135 are respectively fixedly connected to the bottom plate of the first bracket 12, that is, the first transmission belt 135 and the bottom plate of the first bracket 12 together form a closed loop structure.

[0075] Furthermore, in order to ensure the synchronization of the movement of the first bracket 12, as shown in FIG. Figure 2 As shown, a first connecting frame 14 is provided between the two first brackets 12 and on the left side of the first bracket 12, and the front and rear ends of the first connecting frame 14 are respectively fixedly connected to the bottom plate of the first bracket 12. The first brackets 12 and the first connecting frame 14 together form a U-shaped structure with the opening facing the right.

[0076] like Figure 4 As shown, the vehicle lifting unit 2 includes a lifting platform 21 for carrying the vehicle, and the lifting platform 21 is provided with a first avoidance hole for accommodating the battery exchange unit 7. The left and right ends of the lifting platform 21 are respectively provided with a lifting frame 22 that spans the slide 1. The lifting platform 21 is slidably connected to the lifting frame 22, and a second driving mechanism is provided between the lifting frame 22 and the lifting platform 21 for driving the lifting platform 21 to move up and down.

[0077] The lifting frame 22 includes a longitudinal beam 221 extending in the front-to-back direction. Both ends of the longitudinal beam 221 are respectively provided with vertical beams 222 for supporting the longitudinal beam 221 .

[0078] As a specific implementation method, Figure 4As shown, in this embodiment, the left and right ends of the lifting platform 21 extend into the lifting frame 22, and the inner side surfaces of the vertical beams 222 (the inner side being the side opposite the two vertical beams 222 in the same lifting frame 22) are slidably connected to the lifting platform 21 via sliding assemblies. The sliding assemblies include guide plates fixedly disposed on the inner side surfaces of the vertical beams 222 and guide shoes disposed on the lifting platform 21.

[0081] By providing independent lifting frames 22 on either side of the lifting platform 21, the vehicle body height limitation can be overcome compared to traditional gantry structures. Traditional gantry structures require a gantry structure that is larger than the sum of the vehicle body height and the lifting height to prevent collision between the vehicle body and the top frame after the vehicle body is lifted. The present invention provides independent lifting frames 22 on either side of the lifting platform 21, eliminating the vehicle body height limitation and adapting to locations with low floor heights, such as underground garages.

The third lifting belt 3334 is wound around the third lifting wheel 3333, and one end of the third lifting belt 3334 is fixedly connected to the third lifting wheel 3333, and the other end of the third lifting belt 3334 passes around the second transition wheel 3336 from above and is fixedly connected to the far end of the transfer frame (the end away from the third rotating shaft 331 in a direction perpendicular to the third rotating shaft 331) through the third clamping assembly 3216.

[0091] Furthermore, if Figure 13 As shown, a third transition wheel for supporting the third lifting belt 3334 is provided on the first top frame 311 in front of the second transition wheel 3336. Preferably, only one third transition wheel is provided on the first top frame 311 in front of the second transition wheel 3336, and the third transition wheel is coaxially arranged with the first transition wheel 3335.

The other end of the third lifting belt 3334 passes around the second guide post 3218 from below and is connected to the third clamping assembly 3216. Guided by the second guide post 3218, the third lifting belt 3334 is positioned vertically between the second guide post 3218 and the second transition pulley 3336, while the third lifting belt 3334 is positioned horizontally between the second guide post 3218 and the third clamping assembly 3216.

[0096] As a specific embodiment, the transfer arm 322 described in this embodiment is slidably arranged on the lower side of the second top frame 3212, and the suspended end of the transfer arm 322 extends to the front side of the transfer frame through the second vertical frame 3214 located on the front side, and the second vertical frame 3214 located on the front side is provided with an escape opening that allows the transfer arm 322 to pass through.

The first side beam, the second side beam, the second top frame 3212 and the second connecting frame 3211 together form a second vertical frame 3214 with a square frame structure, and the middle space of the second vertical frame 3214 is the escape opening.

[0097] like Figure 7 and Figure 9 As shown, the fourth driving mechanism includes a fourth driving motor 3231 fixedly arranged at the rear end of the second top frame 3212, and a second driving pulley 3232 is fixedly arranged on the power output shaft of the fourth driving motor 3231. The second driving pulley 3232 is connected to the second driven pulley 3234 rotatably arranged at the front end of the second top frame 3212 through a second transmission belt 3233, and the second transmission belt 3233 is connected to the transfer arm 322 through a first clamping plate 3235, and the first clamping plate 3235 limits the relative movement between the second transmission belt 3233 and the transfer arm 322.

[0098] As a specific embodiment, the transfer arm 322 in this embodiment is slidably connected to the second top frame 3212 via a linear guide pair. Preferably, two sets of linear guide pairs extending in the front-to-back direction are provided between the transfer arm 322 and the second top frame 3212, and the fourth drive mechanism is located between the two sets of linear guide pairs.

[0099] Furthermore, in order to increase the stroke of the secondary telescopic arm 3222 for moving the battery without increasing the size of the battery transfer unit 3 in the front-to-back direction, as shown in FIG. Figure 11 As shown, the transfer arm 322 adopts a retractable mechanism.

[0100] like Figure 11 and Figure 12As shown, the transfer arm 322 includes a primary telescopic arm 3221 and a secondary telescopic arm 3222 slidably mounted on the primary telescopic arm 3221. The secondary telescopic arm 3222 can slide back and forth relative to the primary telescopic arm 3221. A fifth drive mechanism is disposed between the secondary telescopic arm 3222 and the primary telescopic arm 3221 for driving the secondary telescopic arm 3222 to move back and forth relative to the primary telescopic arm 3221. The second transmission belt 3233 is fixedly connected to the rear end of the primary telescopic arm 3221 via a first clamping plate 3235.

[0101] like Figure 11 As shown, at least one clamping assembly 3223 is provided at each of the front and rear ends of the secondary telescopic arm 3222. Each clamping assembly 3223 includes a clamping cylinder, with the piston rod of the clamping cylinder facing outward (the side facing the front and rear clamping assemblies 3223 is considered the inward side). A clamping block is fixed to the piston rod of the clamping cylinder. Preferably, the clamping cylinder is a rotary compression cylinder.

[0102] As a specific embodiment, the front and rear ends of the secondary telescopic arm 3222 in this embodiment are each equipped with two sets of clamping assemblies 3223. The secondary telescopic arm 3222 comprises, from front to back, a transverse frame extending laterally. A connecting beam extending longitudinally is disposed between the two transverse frames. The ends of the connecting beam are fixedly connected to the transverse frames, and the connecting beam and transverse frames together form an I-shaped structure. Clamping assemblies 3223 are disposed on both the left and right ends of the transverse frame.

[0103] As a specific implementation, the secondary telescopic arm 3222 in this embodiment is slidably connected to the primary telescopic arm 3221 via a linear guide pair.

[0104] like Figure 11 and Figure 12 As shown, the fifth driving mechanism includes third pulleys 3224 rotatably disposed at the front and rear ends of the first telescopic arm 3221, respectively, with a third transmission belt 3225 disposed between the two third pulleys 3224. The front end of the second top frame 3212 is fixedly connected to the third transmission belt 3225 via a second clamping plate 3226, and the rear end of the second telescopic arm 3222 is fixedly connected to the third transmission belt 3225 via a third clamping plate 3227. When the first clamping plate 3235 moves to the front extreme position, the third clamping plate 3227 moves relative to the first telescopic arm 3221 to the front extreme position of the first telescopic arm 3221.

[0105] Preferably, the third transmission belt 3225 is disposed on the left and / or right side of the primary telescopic arm 3221. As a specific implementation, the fifth driving mechanism described in this embodiment includes only one third transmission belt 3225, and the third transmission belt 3225 is disposed on the left side of the primary telescopic arm 3221.

[0106] Here, the fifth driving mechanism is not equipped with a power component, but realizes the two-stage telescopic extension of the transfer arm 322 through linkage with the fourth driving mechanism, that is, only the fourth driving motor 3231 is needed to realize the sliding between the first-level telescopic arm 3221 and the second top frame 3212, and the sliding between the second-level telescopic arm 3222 and the first-level telescopic arm 3221, which reduces the complexity of the structure and the production cost, and achieves the purpose of energy saving and consumption reduction.

[0107] Furthermore, in order to reduce the friction during the movement of the battery, e.g. Figure 7 and Figure 10 As shown, a plurality of supporting rollers 3219 are evenly distributed along the front-to-back direction on the second bracket 3213 , and a supporting roller 3219 is provided on the second vertical frame 3214 at the lower edge of the avoidance opening.

[0108] like Figure 14 As shown, the front wheel alignment unit includes a first mounting frame 51 , in which front wheel alignment components 52 having the same structure and arranged symmetrically on both sides are arranged.

[0109] like Figure 15 As shown, the front wheel positioning component 52 includes a first slide plate 521 that can slide back and forth relative to the first mounting frame 51. As a specific embodiment, the first slide plate 521 in this embodiment is slidably connected to the first mounting frame 51 via a linear guide pair. Preferably, two sets of linear guide pairs are provided between the first slide plate 521 and the first mounting frame 51.

[0110] A V-shaped positioning roller assembly is provided on the first slide 521, located in the middle of the first slide 521 in the left-right direction. The positioning roller assembly comprises two sets of first roller assemblies 522, arranged diagonally outward and upward (with the opposing sides of the two sets of first roller assemblies 522 as the inner sides), with the two sets of first roller assemblies 522 arranged symmetrically front to back. A support frame 523 is provided below the first roller assemblies 522, and the first roller assemblies 522 are fixedly connected to the first slide 521 via the support frame 523. A second clearance hole is provided on the first mounting frame 51 for clearing the positioning roller assembly, allowing the positioning roller assembly to be exposed externally through the second clearance hole.

[0111] A first push plate 524 is disposed within the second avoidance hole, above the positioning roller assembly. A first ejection frame 525 is fixedly mounted on the outer side of the first push plate 524 (with the inner side facing the two front wheel positioning components 52 as the inner side). The first ejection frame 525 is slidably connected to the first slide 521 via a linear guide pair. A sixth drive mechanism is disposed between the first ejection frame 525 and the first slide 521, for driving the first ejection frame 525 to slide left and right relative to the first slide 521.

[0112] like Figure 15 As shown, the sixth drive mechanism includes a first lead screw 5261 extending in the left-right direction, with both ends of the first lead screw 5261 rotatably connected to the first slide 521 via bearing assemblies. A sixth drive motor 5262 is fixedly mounted on the inner end of the first slide 521 (with the side opposite the two front wheel positioning components 52 as the inner side), and the power output shaft of the sixth drive motor 5262 is connected to the inner end of the first lead screw 5261 (with the side opposite the two front wheel positioning components 52 as the inner side). A first nut that cooperates with the first lead screw 5261 is fixedly mounted on the first ejection frame 525.

[0113] As a specific implementation, the first ejection frame 525 described in this embodiment includes a first top plate extending outward perpendicularly to the first push plate 524, and the first top plate is slidably connected to the second slide through a connecting block, and the second slide is slidably connected to the first slide 521 through a linear guide pair.

[0114] Furthermore, since the positioning roller group needs to move forward and backward according to the vehicle type during operation, the size of the second avoidance hole in the front-to-back direction is larger than the size of the positioning roller group in the front-to-back direction. This prevents the wheels of the vehicle from getting stuck in the gap between the positioning roller group and the rear edge of the second avoidance hole when entering the charging and swapping station. Figure 1 and Figure 14 As shown, support plates 528 are provided on both the front and rear sides of the positioning roller group.

[0115] As a specific implementation method, Figure 15 and Figure 16As shown, the first mounting frame 51 is provided with first mounting plates 527 on the left and right sides of the positioning roller assembly. Each of the first mounting plates 527 is provided with a clearance notch for accommodating the first slide plate 521. A chain 5271 is provided on the inner side of each of the first mounting plates 527 (the inner side being the side facing each other), and the positioning roller assembly is located within the chain 5271. Within the chain 5271, and outside the positioning roller assembly, are multiple sprockets 5272 for supporting the chain 5271. The sprockets 5272 are rotatably connected to the first mounting plates 527. The portion of the chain 5271 located above the positioning roller assembly is horizontal. Multiple support plates 528 are provided on the front and rear sides of the positioning roller group, and the support plate 528 located on the innermost side (the side close to the positioning roller group is the inner side) is fixedly connected to the outer end of the first roller assembly 522 (the side opposite to the two first roller assemblies 522 is the inner side), and the two ends of the support plate 528 are respectively fixedly connected to the chain 5271.

[0116] In this way, when the positioning roller group moves back and forth, the chain 5271 installed with the support plate 528 will be driven to move together through the positioning roller group, and the sprocket 5272 will rotate, so that the support plate 528 can always fill the gap between the positioning roller group and the front edge of the second avoidance hole and the gap between the positioning roller group and the rear edge of the second avoidance hole.

[0117] like Figure 14 As shown, a transition plate 53 is disposed between the two front wheel positioning components 52, and the inner ends of the first slide plates 521 (with the inner sides being the sides opposite the two front wheel positioning components 52) are fixedly connected to the transition plates 53. A seventh drive mechanism is disposed between the transition plates 53 and the first mounting frame 51 for driving the transition plates 53 to move forward and backward relative to the first mounting frame 51.

[0118] The seventh drive mechanism includes a second lead screw 541 extending in the front-to-back direction. A second nut 542 is fixedly mounted on the transition plate 53 and engages with the second lead screw 541. A seventh drive motor 543 is mounted on the first mounting frame 51 on one side of the transition plate 53. The second lead screw 541 is connected to the power output shaft of the seventh drive motor 543 via a second transmission assembly 544. As a specific embodiment, the second transmission assembly 544 in this embodiment can utilize a synchronous belt drive or a gear drive. Preferably, the second transmission assembly 544 utilizes a synchronous belt drive.

[0119] like Figure 1As shown, the rear wheel alignment unit includes a second mounting frame 61 , in which two rear wheel alignment components 62 having the same structure and arranged symmetrically on the left and right are arranged.

[0120] like Figure 17 As shown, the rear wheel positioning component 62 includes a second roller assembly 621, and second mounting uprights 622 are provided at the front and rear ends of the second roller assembly 621 for supporting the second roller assembly 621. The upper end of the second mounting upright 622 is fixedly connected to the second roller assembly 621, and the lower end of the second mounting upright 622 is fixedly connected to the second mounting frame 61. The second mounting frame 61 is provided with a third avoidance hole for avoiding the second roller assembly 621, that is, the second roller assembly 621 is exposed to the outside through the third avoidance hole.

[0121] The second mounting frame 61 is provided with a second push plate 623 that spans the second roller assembly 621. The second push plate 623 is slidably connected to the second mounting plate 622 or the second mounting frame 61, allowing for left and right sliding relative to the second mounting frame 61. In a specific embodiment, the second push plate 623 in this embodiment is slidably connected to the outer side of the second mounting plate 622 (with the inner side being the side opposite the second mounting plate 622) via a linear guide pair. An eighth drive mechanism is provided between the second mounting frame 61 and the second push plate 623 for driving the second push plate 623 to slide left and right relative to the second mounting frame 61.

[0122] As a specific implementation method, Figure 17 As shown, the eighth drive mechanism described in this embodiment includes a third screw 6241 extending in the transverse direction and arranged below the second roller assembly 621, and the two ends of the third screw 6241 are rotatably connected to the second mounting frame 61 through bearing assemblies. The third screw 6241 is provided with a third nut 6242 that cooperates with the third screw 6241. The third nut 6242 is fixedly provided with a third slide 6243 extending in the longitudinal direction, and the two ends of the third slide 6243 pass through the second mounting plate 622 and are fixedly connected to the second push plate 623. The second mounting frame 61 is fixedly provided with an eighth drive motor 6244, and the power output shaft of the eighth drive motor 6244 is connected to the third screw.

[0123] Furthermore, the modular charging and swapping station also includes a base 8, the underframe of the slide 1 is fixedly connected to the base 8, the lifting frame 22 of the vehicle lifting unit 2 is fixedly connected to the base 8, the main frame of the battery transfer unit 3 is fixedly connected to the base 8, and the first mounting frame 51 and the second mounting frame 61 are both fixedly connected to the base 8.

[0124] The implementation principle of the embodiment of this application is:

[0125] First, the seventh driving mechanism is activated to adjust the distance between the positioning roller group and the battery exchange unit 7 according to the model of the vehicle, so that the distance between the positioning roller group and the battery exchange unit 7 is equal to the distance between the front wheel of the vehicle and the battery.

[0126] Second, the vehicle is driven onto the battery swap platform until the front wheels are positioned on the positioning rollers. Then, the sixth and eighth drive mechanisms are activated simultaneously to center the vehicle in the left and right directions, so that the battery swap unit 7 is aligned with the vehicle's battery, that is, the battery is directly above the battery swap unit 7.

[0127] Third, the second drive mechanism of the lifting unit is activated, driving the lifting platform 21 to rise, thereby lifting the entire vehicle, and then the battery replacement unit 7 is raised to remove the battery from the vehicle. At the same time, the first drive mechanism of the slide 1 is activated, driving the first bracket 12 to move to the front and rear sides of the battery replacement unit 7.

[0128] Fourth, after the battery is disassembled, the battery exchange unit 7 descends. Since the upper side of the first bracket 12 is located above the battery exchange unit 7 when the battery exchange unit 7 descends to the lower limit position, the battery will eventually be supported by the first bracket 12, and the upper side of the battery exchange unit 7 will be separated from the battery.

[0129] Fifth, the first driving mechanism is activated, driving the removed battery to move to the left through the first bracket 12. When the first bracket 12 moves to the left limit position, the second bracket 3213 of the battery transfer unit 3 is inserted under the battery.

[0130] Sixth, the third drive mechanism activates, driving the transfer unit 32 upward until the second bracket 3213 is aligned with an empty charging station on a certain level of the battery rack 4. Simultaneously, the clamping cylinders in the clamping assembly 3223 activate, clamping the battery longitudinally. The fourth drive motor 3231 then activates, causing the transfer arm 322 to move the battery to be charged to an empty charging station on the battery rack 4.

[0131] Seventh, the clamping cylinder in the clamping assembly 3223 is actuated, and the clamping assembly 3223 releases the battery. Then the fourth drive motor 3231 is actuated, driving the transfer arm 322 to retract. Then the third drive mechanism is actuated, driving the transfer component 32 to move up and down as a whole, until the second bracket 3213 is aligned with a charging position in the battery rack 4 where a charged battery is placed, and then the fourth drive motor 3231 is actuated, thereby extending the transfer arm 322. Then the clamping cylinder in the clamping assembly 3223 is actuated to clamp the charged battery. Then the fourth drive motor 3231 is actuated to move the fully charged battery to the second bracket 3213.

[0132] Eighth, the third driving mechanism is actuated to drive the transfer component 32 to move downward as a whole, thereby placing the charged battery on the first bracket 12. Then the first driving mechanism is actuated to move the battery to the top of the battery replacement unit 7.

[0133] Ninth, the battery replacement unit 7 is raised and the battery is installed on the vehicle to complete the battery replacement operation.
