[0038] During transportation, the protective cover assembly 3 forms a closed space to protect the battery swap device 4 and the battery 100; when swapping batteries, the protective cover assembly 3 is raised in height through the lifting mechanism, and then the wing door mechanism is unfolded, which not only facilitates the operation of the battery swap device 4, but also protects the battery swap device 4 to prevent rainwater from dripping directly into the area where the battery swap device 4 is located.

[0039] The lifting mechanism includes columns 301 fixedly arranged on both sides of the bottom plate 5, and a movable frame 305 is movably arranged on the columns 301, and the movable frame 305 is connected to a lifting device 302. The lifting device 302 is one of a hydraulic telescopic rod, an electric telescopic rod and a screw lift. The hydraulic telescopic rod, the electric telescopic rod and the screw lift can all adjust their own lengths to control the lifting of the movable frame 305. In this application, a hydraulic telescopic rod is used.

[0040] At least two columns 301 are provided on one side of the bottom plate 5, and a fixed baffle 304 is provided between the two columns 301. A movable baffle 303 located outside the fixed baffle 304 is connected to the movable frame 305. The movable baffle 303 moves with the lifting of the movable frame 305, and cooperates with the fixed baffle 304 to protect the side of the protective cover assembly 3, so as to prevent rainwater from drifting into the inner side of the protective cover assembly 3 from the side to damage the battery 100 and related electrical appliances.

[0041] A control device 2 is installed on one side of the protective cover assembly 3. In order to avoid the control device 2, preferably, a movable baffle 303 close to the control device 2 is arranged between the two columns 301 and the movable baffle 303 does not protrude from the outer surface of the column 301, that is, preferably, the width of the movable baffle 303 is less than the distance between the outer surfaces of the two columns 301. In some other embodiments, the fixed baffle 304 and the movable baffle 303 are limited by a guide groove (not shown), which can be arranged on both sides of the fixed baffle 304, and the movable baffle 303 is inserted into the guide groove from top to bottom; or in some other embodiments, the guide groove is arranged on both sides of the movable baffle 303 and a guide rail is arranged on the column 301 or the fixed baffle 304, and the movable baffle 303 is limited by the guide groove to only be lifted and lowered in the up and down direction relative to the fixed baffle 304, thereby increasing the stability and reliability of the protective cover assembly 3.

[0042] The wing door mechanism includes a top plate 307 fixedly arranged between two movable frames 305, and wings 308 hinged to the movable frames 305 are arranged on both sides of the top plate 307. A flip jacking device 306 is hinged to the wings 308, and one end of the flip jacking device 306 away from the wings 308 is hinged to the movable frames 305. The flip jacking device 306 controls the wings 308 to flip through its own telescopic control, thereby realizing the opening and closing of the wings 308; when the wings 308 are closed and the movable frames 305 are at the lowest position, the protective cover assembly 3 forms a rectangular protective cover to surround the battery 100 and the battery replacement device 4.

[0043] The flipping and lifting device 306 is one of a hydraulic telescopic rod, an electric telescopic rod and a screw lifter, and the hydraulic telescopic rod, the electric telescopic rod and the screw lifter can adjust their own lengths to control the flipping of the flying wing 308. In the present application, a hydraulic telescopic rod is used.

[0044] The battery exchange device 4 includes at least two mobile frames 401 arranged at intervals and spanning the battery 100, a lifting frame 408 is arranged between the two mobile frames 401, a transmission device for driving the lifting frame 408 to rise and fall is installed on the mobile frame 401, a telescopic arm 428 is installed on the lifting frame 408, a sling 426 is arranged at the telescopic end of the telescopic arm 428, a guide rail 423 is vertically arranged on the mobile frame 401, and a first lifting guide wheel 420, a second lifting guide wheel 421 and a third lifting guide wheel 425 cooperating with the guide rail 423 are arranged on the lifting frame 408, the first lifting guide wheel 420 and the third lifting guide wheel 425 are clamped on both sides of the guide rail 423, and the second lifting guide wheel 421 is in contact with the end surface of the guide rail 423.

[0045] The lifting frame 408 is lifted and lowered through the transmission device to drive the telescopic arm 428 to adjust the height position. After the hanger 426 fixes the battery 100, the position of the battery 100 is adjusted by lifting the lifting frame 408, moving the mobile frame 401, and extending and retracting the telescopic arm 428, thereby installing the battery 100.

[0046] During the lifting process of the lifting frame 408, the first lifting guide wheel 420, the second lifting guide wheel 421 and the third lifting guide wheel 425 abut and limit the three side walls of the guide rail 423 to ensure the stability of the lifting of the lifting frame 408 and reduce the wear between the guide rail 423 and the guide wheels by rolling.

[0047] The transmission device includes a first driving gear 422 and a first driven gear 403 which are arranged to rotate with an interval between the upper and lower parts. A lifting chain 402 is provided on the meshing sleeve of the first driving gear 422 and the first driven gear 403. A connecting seat 419 which is fixedly connected to the lifting frame 408 is provided on the lifting chain 402. The first driving gear 422 is connected to a driving shaft 411, and the driving shaft 411 is connected to a speed reducer 412, and the speed reducer 412 is connected to a lifting motor 413. The lifting motor 413 rotates the driving shaft 411 through the speed reducer 412, thereby driving the lifting chain 402 to drive the lifting frame 408 to rise and fall in the vertical direction. The transmission device can also use a screw lifting structure.

[0048] The mobile frame 401 is in the shape of a gate, so that it can cross the battery 100 during the movement. The lower end of the support frame 401 is rotatably provided with a walking wheel 404, and the walking wheel 404 is fixedly connected to a second driven gear. The support frame 401 is rotatably provided with a second driving gear 418, and a walking chain 417 is meshed with the second driving gear 418 and the second driven gear, and the second driving gear 418 is connected to a walking motor 416. The walking motor 416 drives the second driving gear 418 to rotate, and cooperates with the walking chain 417 to drive the second driven gear and the walking wheel 404 to rotate synchronously, thereby realizing the movement of the mobile frame 401.

[0049] The bottom plate 5 is provided with a track 405 that cooperates with the mobile frame 401, and a first reinforcing rod 414 located at the lower end of the mobile frame 401 is connected between the two mobile frames 401. The first reinforcing rod 414 is fixedly connected with a sliding limit seat 406 that slides and engages on the track 405. The track 405 is I-shaped. When the mobile frame 401 moves along the track 405 through the walking wheels 404, the sliding limit seat 406 always maintains a sliding fit with the track 405, and the sliding limit seat 406 is provided with an inwardly curved claw structure, so as to cooperate with the I-shaped track 405 to prevent the battery exchange device 4 from derailing and overturning during movement. Among them, the first reinforcing rod 414 can connect the two support frames 401 into a whole and enhance the structural strength.

[0050] The upper surface and both side end surfaces of the first reinforcing rod 414 are provided with buffer elastic blocks 415. The buffer elastic blocks 415 can buffer the impact force when the lifting frame 408 descends and the impact force of the supporting frame 401 and other structures after moving, so as to prevent the related structures from being damaged by impact.

[0051] The lifting frame 408 is detachably connected with a second reinforcing rod 407 perpendicular to the two support frames 401. The second reinforcing rod 407 can strengthen the structural strength of the lifting frame 408. The second reinforcing rod 407 is only used for the transportation process of the entire battery replacement equipment 4. When performing subsequent battery replacement operations, the second reinforcing rod 407 needs to be removed to prevent the second reinforcing rod 407 from affecting the lifting of the battery 100.

[0052] The fixed end of the telescopic arm 428 is rotatably connected to the lifting frame 408, and a swing telescopic rod 410 is provided on the lifting frame 408. One end of the swing telescopic rod 410 is hinged to the fixed end of the telescopic arm 428, and the other end of the swing telescopic rod 410 is hinged to the lifting frame 408. The swing telescopic rod 410 controls the overall small-angle horizontal swing of the telescopic arm 428 by telescoping, so as to better meet the installation requirements of the battery 100. An arc-shaped guide groove 409 is provided on the lifting frame 408, and a roller 427 that rolls with the arc-shaped guide groove 409 is rotatably installed on the fixed end of the telescopic arm 428. During the swinging process, the telescopic arm 428 realizes stable swinging through the roller 427 cooperating with the arc-shaped guide groove 409, and can also reduce the load at the rotating connection of the telescopic arm 428. The maximum lifting height of the telescopic arm 428 by the lifting frame 408 is not less than twice the height of the battery 100. After the telescopic arm 428 lifts the battery 100, it needs to cross other placed batteries 100. In order to prevent the placed batteries 100 from affecting the movement of the battery exchange equipment 4, the maximum lifting height of the lifting frame 408 is set to twice the height of the battery 100. At this time, the lifted battery 100 moves above the placed batteries 100.

[0053] After the battery exchange device 4 is moved by the mobile frame 401, the low-charged battery on the electric heavy truck is lifted by adjusting the height of the lifting frame 408 and the position of the hoist 426 with the telescopic arm 428, and the low-charged battery is placed on the base plate 5. The battery exchange device 4 is then controlled to move above the fully-charged battery, and the lifting frame 408 is lowered to lift the fully-charged battery. During the movement of the mobile frame 401, the telescopic arm 428 does not extend, and the fully-charged battery moves horizontally from directly above the other batteries, thereby preventing the battery exchange device 4 from overturning due to uneven force. After moving to the designated position, the telescopic arm 428 is extended again to move the fully-charged battery to the installation position of the electric heavy truck, so as to replace the battery.

[0054] A fixing seat 309 is fixed on the column 301, a plug 310 is provided on the fixing seat 309, a matching plate 424 is fixed on the power exchange device 4, and the plug 310 can movably penetrate the matching plate 424 and the fixing seat 309 to fix the power exchange device 4 on the column 301 to prevent the power exchange device 4 from being displaced and overturned during transportation; when the power exchange device 4 is in use, the plug 310 is removed.

[0055] The first hydraulic support leg 501 is connected to the four sides of the base plate 5, and a slide rail 513 is arranged at the bottom of the base plate 5, one end of the slide rail 513 faces the middle of the base plate 5, and the other end of the slide rail 513 faces the long side of the base plate 5, and a slider 515 is slidably connected to the slide rail 513, and a second hydraulic support leg 505 is arranged on the slider 515.

[0056] Most of the existing technologies use trailers for transportation. The trailer is a flatbed with legs and wheels arranged underneath. The trailer and the battery swapping equipment are installed as one. After the battery swapping equipment is working, the trailer cannot be separated from the battery swapping equipment for other purposes, and after the trailer is lifted off the ground by the legs, the weight of its wheels will also increase the load on the supporting legs. The present application uses a flatbed truck 1 to transport the base plate 5, which avoids the situation where the trailer cannot be separated from the battery swapping equipment for other purposes due to the use of a trailer for transportation. No wheels are arranged on the base plate 5 of the present application, which can save the weight of the wheels and reduce the load on the supporting legs. At the same time, it avoids the use of wheels as a support body. The present application increases the stability of the mobile battery swapping station, improves the safety level and reliability, and is beneficial to improving the battery swapping accuracy and efficiency.

[0057] The first hydraulic support leg 501 is used to support the four sides of the bottom plate 5, and then the position of the second hydraulic support leg 505 is adjusted by sliding, so that the second hydraulic support leg 505 moves a certain distance to the middle of the bottom plate 5 and supports it, thereby sharing the weight of the middle of the bottom plate 5 and preventing the bottom plate 5 from being deformed and damaged by pressure. During transportation, the second hydraulic support leg 505 can slide and adjust its position toward the long side of the bottom plate 5, so as to avoid the flatbed truck 1, and facilitate the load-bearing plate of the flatbed truck 1 to move to the bottom of the bottom plate 5 to carry the bottom plate 5. The slide rail 513 can be set along the width direction of the bottom plate 5 or tilted, so that the slider 515 can move a certain distance to the middle of the bottom plate 5, and then adjust the distance between the second hydraulic support legs 505 on both sides to ensure that the flatbed truck 1 has enough insertion space.

[0058] The slider 515 is threadedly connected with a fixing knob 514 for cooperating with the slide rail 513. After the fixing knob 514 is tightly pressed against the slide rail 513, the position of the slider 515 and the second hydraulic support leg 505 can be fixed to prevent the second hydraulic support leg 505 from sliding and hitting and being damaged during transportation. The slide rail 513 does not protrude from the lower surface of the bottom plate 5, so as to prevent the slide rail 513 from affecting the movement of the flatbed vehicle 1 to the bottom of the bottom plate 5.

[0059] The bottom of the base plate 5 is provided with a receiving groove 509 and a mechanical support leg 502 hingedly arranged in the receiving groove 509. The mechanical support leg 502 supports the base plate 1 to prevent the base plate 5 from suddenly falling after the first hydraulic support leg 501 and the second hydraulic support leg 505 fail, causing damage to the battery exchange device 4. The mechanical support leg 502 can be flipped and placed in the receiving groove 509 to avoid the flatbed truck 1; after the mechanical support leg 502 is flipped into the receiving groove 509, the mechanical support leg 502 is fixed in the receiving groove 509 by manually setting a latch or binding wire to prevent the mechanical support leg 502 from deflecting out of the receiving groove 509. The mechanical support leg 502 can also be rotated and stored according to demand. If it is not stored, the receiving groove 509 is not provided.

[0060] The mechanical support leg 502 includes an outer sleeve 510, in which a screw rod 512 extending from the bottom of the outer sleeve 510 is threadedly connected, and a nut 511 located outside the outer sleeve 510 is fixedly sleeved on the screw rod 512. The screw rod 512 is rotated to screw the screw rod 512 out of the outer sleeve 510, thereby adjusting the telescopic length of the mechanical support leg 502, thereby providing support; the nut 511 facilitates the use of a wrench or other tools to rotate the screw rod 512. The screw rod 512 can also be partially provided with a process plane instead of the nut 511, and the leveling function of the mechanical support leg can also be achieved by directly rotating the screw rod 512 through the process plane.

[0061] The lower ends of the first hydraulic support leg 501, the second hydraulic support leg 505 and the mechanical support leg 502 are hinged with a support pad 506. The hinged support pad 506 can make the first hydraulic support leg 501, the second hydraulic support leg 505 and the mechanical support leg 502 better support the ground.

[0062] Two spaced-apart triangular support frames 507 are connected to one short side of the bottom plate 5, and a connecting rod 508 is connected between the two triangular support frames 507. The triangular support frame 507 is a right triangle, and the triangular support frame 507 is fixedly connected to the column 301 to increase the supporting stability of the triangular support frame 507. The control device 2 is installed on the triangular support frame 507, and the connecting rod 508 is connected to the front end of the triangular support frame 507. This setting method can avoid the goose neck of the flatbed vehicle 1.

[0063] Several fixing frames 503 and mounting rods 504 are provided on the bottom plate 5. The fixing frames 503 are used to bundle steel wire ropes, which are fixed on the vehicle body, so as to fix the bottom plate 5 on the flatbed vehicle 1. The mounting rods 504 can be used to install structures such as signs, baffles, and indicator lights.

[0064] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
