Description

Technical Field

[0001] The present invention relates to a battery replacement and transport device for a new energy vehicle battery pack, and in particular to a battery replacement and transport device for a new energy vehicle battery pack. Background Art

[0002] The battery pack replacement and transport device technology for new energy vehicles adopts quick-change battery replacement. Quick-change batteries generally adopt a detachable battery pack installation method for rapid replacement, that is: the replaced battery pack is charged and other battery packs with power stored are installed on the electric vehicle.

[0003] At present, battery swapping equipment is usually moved from the side of the battery swapping vehicle along the width of the battery swapping vehicle to transfer the battery pack between the battery swapping station and the battery swapping vehicle. During the battery swapping process, for passenger cars or trucks, especially heavy trucks, due to the structure of the vehicle itself, the space inside the ordinary battery swapping room of the battery swapping station is limited and is not suitable for battery swapping. The battery pack needs to be transferred to the vehicle location and then replaced. During the replacement process, a transfer vehicle needs to take over and transport the removed battery pack from the bottom of the vehicle, and then transfer the new battery pack to the bottom of the vehicle for installation. However, during the entire process of replacing the battery pack, the new battery pack and the removed battery pack need to be removed from the transfer vehicle and temporarily shelved. Due to the heavy weight of the battery pack, the difficulty of disassembling or installing the new battery pack and the removed battery pack between the transfer vehicle is increased. Summary of the invention

[0004] Based on this, it is necessary to remove the new battery pack and the removed battery pack from the transfer vehicle and temporarily put them aside during the entire process of replacing the battery pack. Due to the heavy weight of the battery pack, the difficulty of disassembling or installing the new battery pack and the removed battery pack on the transfer vehicle is increased. A new energy vehicle battery pack replacement and transfer device is provided.

[0005] A new energy vehicle battery pack replacement and transfer device provided by the present invention includes a transfer box, and also includes: two receiving frames, the receiving frames include support rails; a displacement adjustment device, the displacement adjustment device is used to adjust the displacement of the receiving frames in the X-axis direction, the Y-axis direction and the Z-axis direction; a clearance opening, the clearance opening includes an opening and a clearance channel; a battery pack supporting frame, both sides of the bottom of the battery pack supporting frame are rotatably connected to support shafts, the surface of the support shaft is provided with rollers, and the rollers are slidably set in the support rails; a positioning assembly, the positioning assembly includes a lock, and when the receiving frame is in the transfer box, the lock locks the support shaft.

[0006] Specifically, support wheels are rotatably arranged on both sides of the transfer box, and first motors are fixedly installed at the four corners inside the transfer box. The output ends of the four first motors are respectively connected to the axles of the four support wheels through gear transmission parts.

[0007] It should be understood that the transfer vehicle transfers the new battery to the side of the large vehicle, and then adjusts the receiving frame to lower its height in the Z-axis direction through the displacement adjustment device so that the bottom end of the receiving frame is close to the ground, and then unlocks the locking state of the support shaft by the lock, and cancels the limit of the support shaft by the limit plate, and the battery pack carrier carrying the new battery pack can be directly pulled down from the receiving frame to realize the removal of the new battery pack from the transfer box, and with the support of the rollers, the new battery pack can be moved and supported for temporary shelving, and then the battery pack carrier without carrying the battery pack is moved to the receiving frame, so that the rollers on the battery pack carrier without carrying the battery pack are moved into the support track, and the support shaft of the roller is locked by the lock. The battery pack is then locked and the height of the receiving frame is adjusted in the Z-axis direction by the displacement adjusting device, so that the bottom end of the receiving frame is inside the transfer box. The battery pack carrying frame that does not carry the battery pack is then moved to the bottom of the vehicle through the transfer box to receive the removed battery pack and then transport it out. The removed battery pack is then removed and temporarily shelved by the battery pack carrying frame, and a new battery pack is installed on the transfer box. In the process of replacing the battery pack on the transfer box, there is no need to directly disassemble and assemble the battery pack. The disassembly and assembly of the battery pack and the transfer box can be achieved by directly disassembling and assembling the movable battery pack carrying frame and the transfer box. The battery pack is always supported by a movable frame, which is convenient and quick, and helps to reduce the difficulty of disassembly and assembly.

[0008] In one embodiment, the displacement adjustment assembly includes: two first slide rails, the two first slide rails are fixedly mounted on the inner wall of the transfer box; a second slide rail, the two ends of the second slide rail are slidably mounted on the surfaces of the two first slide rails; a first screw drive assembly, the first screw drive assembly is used to drive the second slide rail to move along the Y-axis direction on the surface of the first slide rail; two sliders, the two sliders are both slidably arranged on the surface of the second slide rail, and the two sliders are also slidably connected to the surfaces of the two supporting frames respectively; two first electric cylinders, the two first electric cylinders are respectively fixedly mounted on the surfaces of the two sliders, and the ends of the piston rods are respectively fixedly connected to the two supporting frames, and the first electric cylinder is used to drive the supporting frame to move in the Z-axis direction on the surface of the slider; a second screw drive assembly, the second screw drive assembly is used to drive the two sliders to move along the X-axis direction on the second slide rail.

[0009] It should be understood that when the position of the battery pack carrier deviates from the relative position of the battery installation point under the vehicle, the battery pack carrier can be moved and adjusted on the X-axis or Y-axis through the displacement adjustment assembly until it is aligned, and then the height can be adjusted in the Z-axis direction to receive the removed battery pack or support a new battery pack.

[0010] Specifically, the first screw drive assembly includes a first screw, which is connected to the end of the second slide rail, and a second motor is installed on the end of the first screw, and the second motor is fixedly installed on the inner wall of the transfer box. The second screw drive assembly includes a second threaded rod, which is threadedly connected to the two sliders, and a third motor is fixedly installed on the end of the second threaded rod, and the third motor is fixedly installed on the surface of the second slide rail.

[0011] In one embodiment, the positioning assembly also includes: a mounting seat, the mounting seat includes a lock cavity, the lock cavity includes a connecting port and a docking port, and the lock buckle is rotatably connected in the connecting port; a plug-in slot, the plug-in slot is arranged on the inner bottom surface of the docking port; a limit plate, the limit plate is plugged into the plug-in slot, and a first support spring is fixedly connected to the bottom surface of the plug-in slot, and a first inclined surface and a second inclined surface are respectively arranged on both sides of the top of the limit plate.

[0012] It should be understood that in the process of the support shaft moving through the connecting port, the second inclined surface will be squeezed first, pressing the limit plate downward and passing through the limit plate. When the support shaft moves into the lock cavity, the limit plate will limit the support shaft, which is helpful to prevent the roller from derailing. When the supporting frame falls to the ground and the battery pack carrier needs to be detached from the supporting track, the battery pack carrier can be directly pulled to drive the support shaft to squeeze the first inclined surface to break through the limit of the limit plate, making it convenient to remove the battery pack carrier from the supporting frame.

[0013] In one embodiment, the lock buckle also includes: a lock track, which is used to confine the support shaft in the lock cavity; an outer tooth ring, which is fixedly connected to the side of the lock buckle; a rack, which is fixedly connected to the surface of the slider and meshes with the outer tooth ring; an elastic support member, which is used to support and maintain the state of the lock buckle in the lock cavity; wherein, in the process of the receiving frame moving to the inside of the transfer box, the rack will mesh with the outer tooth ring, and the outer tooth ring will synchronously drive the lock buckle to lock the support shaft located in the lock cavity in the lock track.

[0014] It should be understood that after the battery pack carrier is moved to the receiving frame, the displacement adjustment device is used to adjust the height of the receiving frame in the Z-axis direction. In the process of moving the receiving frame to the inside of the transfer box, the outer gear ring will engage with the rack, and then under the action of the rack, the outer gear ring will rotate, and the outer gear ring will simultaneously drive the lock to rotate, locking the support shaft in the lock channel, thereby locking the battery pack carrier, and then realizing automatic locking of the battery pack carrier.

[0015] As shown in Figures , , and , in one embodiment, a limiting strip is fixedly connected to the receiving frame, and a limiting channel is formed between the limiting strip and the surface of the receiving frame to limit the support shaft moved to the receiving frame. It should be understood that by setting the limiting strip to form a limiting channel, in the process of installing the battery pack carrier on the receiving frame, by limiting the support shaft, the roller is always limited in the support track during the process of docking the battery pack carrier and the receiving frame, which is conducive to preventing the roller from derailing. .

[0016] The above-mentioned new energy vehicle battery pack replacement and transfer device does not need to directly disassemble the battery pack during the process of replacing the battery pack on the transfer box. The battery pack and the transfer box can be directly disassembled and assembled by directly disassembling and assembling the movable battery pack carrier frame and the transfer box. The battery pack is always supported by a movable frame, which is convenient and quick, and helps to reduce the difficulty of disassembly and assembly.

[0017] When the position of the battery pack carrier deviates from the relative position of the battery installation site under the vehicle, the battery pack carrier can be moved and adjusted on the X-axis or Y-axis through the displacement adjustment component, which is conducive to precise alignment with the battery pack installation site.

[0018] The limit plate will limit the support shaft, which is helpful to prevent the roller from derailing. When the receiving frame falls to the ground and the battery pack carrier needs to be detached from the support track, the battery pack carrier can be directly pulled to drive the support shaft to squeeze the first inclined surface to break through the limit of the limit plate, making it convenient to remove the battery pack carrier from the receiving frame.

[0019] The height of the receiving frame is adjusted in the Z-axis direction through the displacement adjustment device. In the process of moving the receiving frame to the inside of the transfer box, the outer gear ring will engage with the rack. Then, under the action of the rack, the outer gear ring rotates, and the outer gear ring simultaneously drives the lock to rotate, locking the support shaft in the lock channel, thereby locking the battery pack carrier, thereby realizing automatic locking of the battery pack carrier.

[0038] Combine the following Figure 1-Figure 10 The invention describes a new energy vehicle battery pack replacement and transport device.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown in the figure, in one embodiment, a new energy vehicle battery pack replacement and transfer device includes a transfer box 1, and also includes: two receiving frames 2, the receiving frames 2 include support rails 201; a displacement adjustment device, the displacement adjustment device is used to adjust the displacement of the receiving frames 2 in the X-axis direction, the Y-axis direction and the Z-axis direction; a clearance opening, the clearance opening includes an opening 101 and a clearance channel 102; a battery pack carrier 3, both sides of the bottom of the battery pack carrier 3 are rotatably connected to support shafts 4, the surface of the support shaft 4 is provided with rollers 5, and the rollers 5 are slidably set in the support rails 201; a positioning component, the positioning component includes a lock 6, when the receiving frame 2 is inside the transfer box 1, the lock 6 locks the support shaft 4.

[0040] Specifically, support wheels 33 are rotatably provided on both sides of the transfer box 1, and first motors 34 are fixedly installed at the four corners inside the transfer box 1. The output ends of the four first motors 34 are respectively connected to the axles of the four support wheels 33 through gear transmission parts.

[0041] It should be understood that the transfer vehicle transfers the new battery to the side of the large vehicle, and then adjusts the receiving frame 2 to lower its height in the Z-axis direction through the displacement adjustment device, so that the bottom end of the receiving frame 2 is close to the ground, and then the locking state of the support shaft 4 by the lock buckle 6 is unlocked, and the limit plate 16 on the support shaft 4 is cancelled. The battery pack carrier 3 carrying the new battery pack can be directly pulled down from the receiving frame 2 to realize the removal of the new battery pack from the transfer box 1, and with the support of the roller 5, the new battery pack can be moved and supported for temporary shelving, and then the battery pack carrier 3 without carrying the battery pack is moved to the receiving frame 2, so that the roller 5 on the battery pack carrier 3 without carrying the battery pack is moved into the support rail 201, and the roller 5 is locked by the lock buckle 6. The supporting shaft 4 is locked, and then the height of the receiving frame 2 is adjusted in the Z-axis direction through the displacement adjustment device, so that the bottom end of the receiving frame 2 is inside the transfer box 1, and then the battery pack carrier 3 that is not carrying the battery pack is moved to the bottom of the vehicle through the transfer box 1, and the removed battery pack is received and then transported out, and then the removed battery pack is removed and temporarily shelved through the battery pack carrier 3, and the new battery pack is installed on the transfer box 1. In the process of replacing the battery pack on the transfer box 1, there is no need to directly disassemble and assemble the battery pack. The disassembly and assembly between the movable battery pack carrier 3 and the transfer box 1 is directly realized, and the battery pack and the transfer box 1 are disassembled and assembled, and the battery pack always has a movable frame for support, which is convenient and quick, and helps to reduce the difficulty of disassembly and assembly.

[0042] like Figure 1 , Figure 2 , Figure 8 and Fig. 9 As shown, in one embodiment, the displacement adjustment assembly includes two first slide rails 7, and the two first slide rails 7 are fixedly mounted on the inner wall of the transfer box 1; a second slide rail 8, and the two ends of the second slide rail 8 are slidably mounted on the surfaces of the two first slide rails 7; a first screw drive assembly 11, and the first screw drive assembly 11 is used to drive the second slide rail 8 to move along the Y-axis direction on the surface of the first slide rail 7; two sliders 9, and the two sliders 9 are both slidably arranged on the surface of the second slide rail 8, and the two sliders 9 are also slidably connected to the surfaces of the two receiving frames 2 respectively; two first electric cylinders 10, and the two first electric cylinders 10 are respectively fixedly mounted on the surfaces of the two sliders 9, and the ends of the piston rods are respectively fixedly connected to the two receiving frames 2, and the first electric cylinders 10 are used to drive the receiving frames 2 to move in the Z-axis direction on the surfaces of the sliders 9; a second screw drive assembly 12, and the second screw drive assembly 12 is used to drive the two sliders 9 to move along the X-axis direction on the second slide rail 8.

[0043] It should be understood that when the position of the battery pack carrier 3 deviates from the relative position of the battery installation point under the vehicle, the battery pack carrier 3 can be moved and adjusted on the X-axis or Y-axis through the displacement adjustment component, which is conducive to precise alignment with the battery pack installation point. After alignment, the height adjustment in the Z-axis direction is performed to receive the removed battery pack or support a new battery pack.

[0044] Specifically, the first screw drive assembly 11 includes a first screw, which is connected to the end of the second slide rail 8, and a second motor is installed at the end of the first screw, and the second motor is fixedly installed on the inner wall of the transfer box 1. The second screw drive assembly 12 includes a second threaded rod, which is threadedly connected to the two sliders 9, and a third motor is fixedly installed at the end of the second threaded rod, and the third motor is fixedly installed on the surface of the second slide rail 8.

[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment, the positioning assembly also includes: a mounting seat 13, the mounting seat 13 includes a lock cavity 14, the lock cavity 14 includes a connecting port 1401 and a docking port 1402, and the lock buckle 6 is rotatably connected in the connecting port 1401; a plug-in slot 15, the plug-in slot 15 is opened on the inner bottom surface of the docking port 1402; a limit plate 16, the limit plate 16 is plugged into the plug-in slot 15, and a first support spring 17 is fixedly connected to the bottom surface of the plug-in slot 15, and a first inclined surface 1601 and a second inclined surface 1602 are respectively opened on both sides of the top of the limit plate 16.

[0046] It should be understood that in the process of the support shaft 4 moving through the connecting port 1401, the second inclined surface 1602 will be squeezed first, pressing the limit plate 16 downward and passing through the limit plate 16. When the support shaft 4 moves into the lock cavity 14, the limit plate 16 will limit the support shaft 4, which is helpful to prevent the roller 5 from derailing, and when the supporting frame 2 falls to the ground and the battery pack carrier 3 needs to be detached from the supporting rail 201, the battery pack carrier 3 can be directly pulled to drive the support shaft 4 to squeeze the first inclined surface 1601 to break through the limit of the limit plate 16, so as to facilitate the removal of the battery pack carrier 3 from the supporting frame 2.

[0047] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, in one embodiment, the lock buckle 6 also includes: a lock track 18, which is used to confine the support shaft 4 in the lock cavity 14; an outer toothed ring 19, which is fixedly connected to the side of the lock buckle 6; a rack 20, which is fixedly connected to the surface of the slider 9 and meshes with the outer toothed ring 19; an elastic support member, which is used to support and maintain the state of the lock buckle 6 in the lock cavity 14; wherein, in the process of the receiving frame 2 moving to the inside of the transfer box 1, the rack 20 will mesh with the outer toothed ring 19, and the outer toothed ring 19 will synchronously drive the lock buckle 6 to lock the support shaft 4 located in the lock cavity 14 in the lock track 18.

[0048] It should be understood that after the battery pack carrier 3 moves onto the receiving frame 2, the receiving frame 2 is adjusted to lift its height in the Z-axis direction through the displacement adjustment device. In the process of moving the receiving frame 2 to the inside of the transfer box 1, the outer gear ring 19 will engage with the rack 20, and then under the action of the rack 20, the outer gear ring 19 rotates, and the outer gear ring 19 simultaneously drives the lock buckle 6 to rotate, locking the support shaft 4 in the lock track 18, thereby locking the battery pack carrier 3, and then realizing automatic locking of the battery pack carrier 3.

[0049] like Figure 5 and Figure 6 As shown, in one embodiment, an arc-shaped clearance channel 21 is opened on the first inclined surface 1601 of the limiting plate 16, and the lock buckle 6 is slidably arranged in the arc-shaped clearance channel 102.

[0050] like Figure 2 , Figure 8 and Fig. 9 As shown, in one embodiment, a limiting strip 22 is also fixedly connected to the receiving frame 2, and a limiting channel is formed between the limiting strip 22 and the surface of the receiving frame 2 to limit the support shaft 4 moved to the receiving frame 2. It should be understood that by providing the limiting strip 22 to form a limiting channel, in the process of installing the battery pack carrier 3 on the receiving frame 2, by limiting the support shaft 4, the roller 5 is always limited in the support track 201 during the process of docking the battery pack carrier 3 with the receiving frame 2, which is conducive to preventing the roller 5 from derailing.

[0051] like Figure 1 and Figure 7As shown, in one embodiment, the battery pack carrier 3 further includes: a lifting platform 23, the lifting platform has four lifting legs 2301, and the four lifting legs 2301 are respectively slidably plugged on both sides of the battery pack carrier 3; two battery positioning pins 24, and the two battery positioning pins 24 are respectively fixedly connected to the two ends of the lifting platform 23. It should be understood that the sliding connection between the lifting legs 2301 and the battery pack carrier 3 provides a degree of freedom for further adjusting the carrying height, and the battery positioning pins 24 are provided to be plugged into the docking port 1402 on the battery pack, so as to realize the positioning of the battery pack carried on the lifting platform 23.

[0052] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one embodiment, the elastic support member includes: an arc-shaped limit groove 25, which is provided on the surface of the mounting seat 13; a linkage frame 26, which is fixedly connected to the surface of the outer toothed ring 19 and slides through the arc-shaped limit groove 25; and an arc-shaped spring 27, which is located in the arc-shaped limit groove 25, and whose two ends are respectively fixedly connected to the inside of the arc-shaped limit groove 25 and the linkage frame 26. It should be understood that by providing the arc-shaped spring 27, the outer toothed ring 19 that is not subjected to external force is supported and maintained under the support of the linkage frame 26, thereby maintaining the unlocked state of the lock buckle 6.

[0053] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, in one embodiment, a lap limit assembly is arranged between the linkage frame 26 and the lifting leg 2301 close to the linkage frame 26, and the lap limit assembly includes: a lap groove 28, which is opened at the bottom end of the lifting leg 2301 close to the linkage frame 26; and a lap pin 29, which is fixedly connected to the end of the linkage frame 26. It should be understood that after the battery pack carrier 3 is plugged into the receiving frame 2, under the limitation of the limiting plate 16, when the position of the battery pack carrier 3 is limited, the lap pin 29 will overlap in the lap groove 28, and with the cooperation of the lap pin 29 and the lap groove 28, it is beneficial to limit the position of the lifting leg 2301 relative to the battery pack carrier 3, which is beneficial to reduce the degree of shaking that occurs in the process of lifting the battery pack carrier 3 into the transfer box 1 after the connection is completed, and in the later locking process, the lock buckle 6 will drive the lap pin 29 to move through the linkage frame 26, and then away from the lap groove 28, canceling the limitation of the lifting leg 2301, and providing further freedom to adjust the height for the support height required to receive the battery pack or install a new battery pack.

[0054] like Fig.10As shown, in one embodiment, a second electric cylinder 30 is fixedly installed on the inner bottom surface of the transfer box 1, and a push plate 31 is fixedly connected to the end of the piston rod of the second electric cylinder 30, and a ball 32 is rotatably connected to the top of the push plate 31. It should be understood that by providing the second electric cylinder 30, the second electric cylinder 30 pushes the push plate 31 to lift the lifting platform 23, thereby achieving the function of further adjusting the height, and by providing the ball 32, rolling support is provided between the push plate 31 and the lifting platform 23, which is conducive to avoiding the push plate 31 from obstructing the lifting platform 23 when adjusting the movement of the lifting platform 23 in the X-axis or Y-axis direction.

[0055] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
