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. First motors are fixedly installed at four corners inside the transfer box. Output ends of the four first motors are respectively connected to axles of the four support wheels through gear transmission members.

[0007] It should be understood that the transporter transports the new battery to the side of the large vehicle, and then adjusts the receiving frame to lower the height in the Z-axis direction through the displacement adjustment device, so that the bottom end of the receiving frame touches the ground. Then, the locking state of the lock on the support shaft is unlocked, and the limiting of the support shaft by the limiting plate is cancelled. The battery pack carrier carrying the new battery pack can be directly pulled down from the receiving frame to remove 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 placement. Then, the battery pack carrier without a battery pack is moved onto the receiving frame, so that the rollers on the battery pack carrier without a battery pack move into the support track. The support shaft of the roller is locked by the lock. Then, the receiving frame is adjusted to lift the height in the Z-axis direction through the displacement adjustment device, so that the bottom end of the receiving frame is inside the transfer box. Then, the transfer box is used to move the battery pack carrier without a battery pack under the vehicle to receive the removed battery pack and then transport it out. Then, the removed battery pack is removed from the battery pack carrier for temporary placement, and the new battery pack is installed on the transfer box. During 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 between the movable battery pack carrier and the transfer box are directly realized to achieve the disassembly and assembly of the battery pack and the transfer box. And the battery pack always has a movable frame for support, which is convenient and fast, and is beneficial to reducing the disassembly and assembly difficulty.

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

[0009] It should be understood that when there is a deviation in the relative position between the position of the battery pack carrier and the battery installation location on the vehicle floor, the battery pack carrier can be adjusted by moving it in the X-axis or Y-axis directions through the displacement adjustment device. After alignment, the height can be adjusted in the Z-axis direction to receive the removed battery pack or support the new battery pack.

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

[0011] In one embodiment, the positioning assembly further includes: a mounting base, the mounting base includes a locking cavity, the locking cavity includes a connection port and a mating port, and the locking buckle is rotatably connected in the connection port; a plugging groove, the plugging groove is opened on the inner bottom surface of the mating port; a limiting plate, the limiting plate is plugged in the plugging groove, and a first support spring is fixedly connected between the limiting plate and the bottom surface of the plugging groove. First inclined surfaces and second inclined surfaces are respectively opened on both sides of the top end of the limiting plate.

[0012] It should be understood that during the process of the support shaft moving through the connection port, it will first squeeze the second inclined surface, pressing the limiting plate downward and passing through the limiting plate. When the support shaft moves into the locking cavity, the limiting plate will limit the support shaft, which is beneficial to preventing the roller from derailing. And when the receiving frame lands and it is necessary to detach the battery pack carrier from the support track, directly pulling the battery pack carrier can drive the support shaft to squeeze the first inclined surface to break through the limit of the limiting plate, facilitating the detachment of the battery pack carrier from the receiving frame.

[0013] In one embodiment, the locking buckle further includes: a locking track for limiting the support shaft in the locking cavity; an external toothed ring fixedly connected to the side surface of the locking buckle; a rack fixedly connected to the surface of the slider and meshing with the external toothed ring; an elastic support member for supporting and maintaining the state of the locking buckle in the locking cavity; wherein, during the process of the receiving frame moving into the interior of the transfer box, the rack will engage with the external toothed ring, and the external toothed ring will synchronously drive the locking buckle to lock the support shaft located in the locking cavity in the locking track.

[0014] It should be understood that after the battery pack carrier is moved onto the receiving rack, the receiving rack is adjusted by the displacement adjusting device to lift in the Z-axis direction. During the process of moving the receiving rack into the transfer box, the external gear ring will engage with the rack. Then, under the action of the rack, the external gear ring rotates, and the external gear ring synchronously drives the latch to rotate, locking the support shaft in the locking track, thereby locking the battery pack carrier and realizing the automatic locking of the battery pack carrier.

[0015] In one embodiment, a limiting strip is also fixedly connected to the receiving rack. A limiting channel is formed between the limiting strip and the surface of the receiving rack to limit the support shaft moved onto the receiving rack. It should be understood that by setting the limiting strip to form a limiting channel, during the process of installing the battery pack carrier on the receiving rack, through the limitation of the support shaft, the roller is always limited within the support track during the docking process of the battery pack carrier and the receiving rack, which is beneficial to preventing the roller from derailing.

[0016] In the above new energy vehicle battery pack swapping and transfer device, during 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 between the movable battery pack carrier and the transfer box are directly realized to achieve the disassembly and assembly of the battery pack and the transfer box. Moreover, the battery pack always has a movable frame for support, which is convenient and fast, and is beneficial to reducing the disassembly and assembly difficulty.

[0017] When there is a deviation in the relative position between the position of the battery pack carrier and the battery installation position at the bottom of the vehicle, the battery pack carrier can be adjusted to move in the X-axis or Y-axis direction through the displacement adjusting device, which is beneficial to accurately align with the battery installation position.

[0018] The limiting plate will limit the support shaft, which is beneficial to preventing the roller from derailing. And when the receiving rack lands and it is necessary to detach the battery pack carrier from the support track, directly pulling the battery pack carrier can drive the support shaft to squeeze the first inclined surface to break through the limitation of the limiting plate, which is convenient for detaching the battery pack carrier from the receiving rack.

[0019] The receiving rack is adjusted by the displacement adjusting device to lift in the Z-axis direction. During the process of moving the receiving rack into the transfer box, the external gear ring will engage with the rack. Then, under the action of the rack, the external gear ring rotates, and the external gear ring synchronously drives the latch to rotate, locking the support shaft in the locking track, thereby locking the battery pack carrier and realizing the automatic locking of the battery pack carrier.

[0038] Combine the following Figures 1 - 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 , Figure 9 and Figure 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 transporter transports the new battery to the side of the large vehicle, and then adjusts the receiving frame 2 to lower the height in the Z-axis direction through the displacement adjustment device, so that the bottom end of the receiving frame 2 touches the ground. Then, the locking state of the locking buckle 6 on the support shaft 4 is unlocked, and the limit of the limiting 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 remove the new battery pack from the transfer box 1. And with the support of the rollers 5, the new battery pack can be moved and supported to achieve temporary placement. Then, the battery pack carrier 3 without a battery pack is moved onto the receiving frame 2, so that the rollers 5 on the battery pack carrier 3 without a battery pack move into the support track 201. The support shaft 4 of the roller 5 is locked by the locking buckle 6. Then, the receiving frame 2 is adjusted to lift the height 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. Then, the transfer box 1 is used to move the battery pack carrier 3 without a battery pack under the vehicle to receive the removed battery pack, and then transport it out. Then, the removed battery pack is removed from the battery pack carrier 3 and temporarily placed, and the new battery pack is installed on the transfer box 1. During 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 are directly realized to achieve the disassembly and assembly of the battery pack and the transfer box 1. And the battery pack always has a movable frame for support, which is convenient and fast, and is beneficial to reducing the disassembly and assembly difficulty.

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

[0043] It should be understood that when there is a deviation in the relative position between the position of the battery pack carrier 3 and the battery installation location on the vehicle floor, the battery pack carrier 3 can be adjusted by moving in the X-axis or Y-axis through the displacement adjustment device, which is beneficial for accurately aligning with the battery pack installation location. After alignment, the height adjustment in the Z-axis direction is then carried out to receive the removed battery pack or support the new battery pack.

[0044] Specifically, the first screw drive assembly 11 includes a first screw, the first screw 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, the second threaded rod 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] As Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown in

[0046] It should be understood that during the process of the support shaft 4 moving through the connection port 1401, it will first squeeze the second inclined surface 1602, press the limiting plate 16 downward and pass through the limiting plate 16. When the support shaft 4 moves into the lock cavity 14, the limiting plate 16 will limit the support shaft 4, which is beneficial to prevent the roller 5 from derailing. And when the receiving frame 2 lands and it is necessary to detach the battery pack carrier 3 from the support track 201, directly pulling the battery pack carrier 3 can drive the support shaft 4 to squeeze the first inclined surface 1601 to break through the limit of the limiting plate 16, facilitating the detachment of the battery pack carrier 3 from the receiving frame 2.

[0047] As Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, in one embodiment, the latch 6 further includes: a locking track 18 for restricting the support shaft 4 within the locking cavity 14; an external gear ring 19 fixedly connected to the side surface of the latch 6; a rack 20 fixedly connected to the surface of the slider 9 and meshing with the external gear ring 19; an elastic support member for supporting and maintaining the state of the latch 6 within the locking cavity 14. Wherein, during the process of the receiving frame 2 moving into the transfer box 1, the rack 20 engages with the external gear ring 19, and the external gear ring 19 synchronously drives the latch 6 to lock the support shaft 4 located within the locking cavity 14 in the locking track 18.

[0048] It should be understood that after the battery pack carrier 3 moves onto the receiving frame 2, the displacement adjusting device adjusts the receiving frame 2 to lift in the Z-axis direction. During the process of moving the receiving frame 2 into the transfer box 1, the external gear ring 19 engages with the rack 20. Then, under the action of the rack 20, the external gear ring 19 rotates, and the external gear ring 19 synchronously drives the latch 6 to rotate, locking the support shaft 4 in the locking track 18, thereby locking the battery pack carrier 3 and realizing the automatic locking of the battery pack carrier 3.

[0049] As Figure 5 and Figure 6 As shown, in one embodiment, an arc-shaped relief channel 21 is formed on the first inclined surface 1601 of the limiting plate 16, and the latch 6 is slidably disposed within the arc-shaped relief channel 102.

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

[0051] As Figure 1 and Figure 7As shown, in one embodiment, the battery pack carrier 3 further includes: a lifting carrier 23, the lifting platform having four lifting legs 2301, and the four lifting legs 2301 are respectively slidably inserted 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 both ends of the lifting carrier 23. It should be understood that through the sliding connection between the lifting legs 2301 and the battery pack carrier 3, a degree of freedom for further adjusting the carrying height is provided. By providing the battery positioning pins 24, which are used to be inserted into the docking interfaces 1402 on the battery pack, the battery pack carried on the lifting carrier 23 is positioned.

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

[0053] As Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown in, in one embodiment, a lapping and limiting assembly is provided between the linkage frame 26 and the lifting leg 2301 close to the linkage frame 26. The lapping and limiting assembly includes: a lapping groove 28, which is opened at the bottom end of the lifting leg 2301 close to the linkage frame 26; a lapping 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 inserted into the receiving frame 2, under the limitation of the limiting plate 16, with the position of the battery pack carrier 3 being limited, the lapping pin 29 will lap in the lapping groove 28. With the cooperation between the lapping pin 29 and the lapping 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 reducing the shaking degree of the battery pack carrier 3 during the process of being lifted into the transfer box 1 after the insertion is completed. And during the later locking process, the lock 6 will drive the lapping pin 29 to move through the linkage frame 26, and then move away from the lapping groove 28, canceling the limitation on the lifting leg 2301, providing a degree of freedom for further adjusting the support height required for receiving the battery pack or installing a new battery pack.

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

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
