Description

Technical Field

[0001] This utility model relates to the field of battery pack manufacturing technology, and in particular to a battery pack forklift mechanism. Background Technology

[0002] In the new energy vehicle industry chain, efficient battery pack transportation is a core requirement that spans three major stages: manufacturing, battery swapping services, and recycling. These stages all require a series of actions such as precise forking, smooth lifting and lowering, and flexible transportation.

[0003] However, traditional operating methods generally suffer from problems such as low efficiency, long operation time, and insufficient equipment compatibility. Manual hoisting not only poses safety hazards but also has low operating efficiency; while forklift picking improves basic handling capacity, the fixed or limited adjustment range of forklift forks makes it difficult to adapt to battery packs of different sizes, and each adjustment requires additional time, seriously affecting production or battery swapping cycle. Utility Model Content

[0004] The purpose of this invention is to provide a battery pack forking mechanism that can fork battery packs of different sizes.

[0005] The technical solution of this utility model:

[0006] A battery pack fork-lifting mechanism includes fork arms and a fork-lifting mechanism. The fork-lifting mechanism includes a fork-lifting mounting frame, and three fork arms are arranged above the fork-lifting mounting frame. A first linear guide rail is fixed on the front crossbar, middle crossbar, and rear crossbar of the fork-lifting mounting frame. The slide of the first linear guide rail is connected to the bottom of the fork arms. The distance between the three fork arms is adjusted by a pitch-changing mechanism.

[0007] The pitch-changing mechanism includes a fixed crossbar. A fixed crossbar is fixed between the middle crossbar and the rear crossbar on the fork-mounting frame. A fixed base plate is provided above the fixed crossbar. Two second linear guides arranged front and rear are fixed on the fixed crossbar. The slides of the second linear guides are connected to the bottom of the fixed base plate. A rack is fixed on the fixed crossbar between the two second linear guides.

[0008] A first telescopic cylinder is fixed to the fixed base plate via a support frame. A lifting rod is fixed to the end of the push rod of the first telescopic cylinder. The fork arm has a socket for inserting the lifting rod.

[0009] Furthermore, the slides of the first linear guide rails on the front and rear crossbars are connected to the bottom of the fork arm via a connecting block, and a guide rail clamp is fixed on the connecting block.

[0010] Furthermore, the fork arm includes a lower fork connected to the first linear guide rail, a middle fork is provided at the top of the lower fork, and an upper fork is provided at the top of the middle fork; both the front and rear ends of the upper fork are fixed with limit blocks, and a rubber anti-slip pad is fixed between the two limit blocks.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] like Figures 1-12As shown, this utility model provides a first embodiment of a battery pack forking mechanism, including fork arms 102 and a forking mechanism 1. The forking mechanism 1 includes a forking mounting frame 101, and three fork arms 102 are arranged above the forking mounting frame 101. A first linear guide rail 103 is fixed on the front crossbar 1011, the middle crossbar 1012, and the rear crossbar 1013 of the forking mounting frame 101. The slide of the first linear guide rail 103 is connected to the bottom of the fork arms 102, so that the fork arms 102 can move on the first linear guide rail 103. The distance between the three fork arms 102 is adjusted by a pitch mechanism 2, so that battery packs of different sizes can be forked.

[0038] The variable pitch mechanism 2 includes a fixed crossbar 1014. The fixed crossbar 1014 is fixed between the middle crossbar 1012 and the rear crossbar 1013 on the fork-mounting frame 101. A fixed base plate 201 is provided above the fixed crossbar 1014. Two second linear guide rails 202 arranged front and rear are fixed on the fixed crossbar 1014. The slide of the second linear guide rail 202 is connected to the bottom of the fixed base plate 201, so that the fixed base plate 201 can move on the second linear guide rails 202. A rack 203 is fixed on the fixed crossbar 1014 between the two second linear guide rails 202. The rack 203 meshes with a gear 204. The gear 204 is driven by a first drive motor 205, which is fixed on the fixed base plate 201.

[0039] A first telescopic cylinder 207 is fixed on the fixed base plate 201 via a support frame 206. A lifting rod 208 is fixed to the end of the push rod of the first telescopic cylinder 207. The fork arm 102 has an insertion hole 209 for inserting the lifting rod 208.

[0040] When it is necessary to adjust the distance between the three fork arms 102, the first drive motor 205 drives the gear 204 to rotate. Since the gear 204 meshes with the rack 203, and the rack 203 is fixed on the fixed crossbar 1014, the gear 204 can move on the rack 203 after rotation, thereby driving the first drive motor 205 to move, which in turn drives the fixed base plate 201 to move, and then drives the first telescopic cylinder 207 on the support frame 206 to move. When the first telescopic cylinder 207 moves below the fork arm 102, it drives the lifting rod 208 to rise, so that the lifting rod 208 is inserted into the insertion hole 209, so that the lifting rod 208 can pull the fork arm 102 to move simultaneously. Then, the first drive motor 205 drives the gear 204 to rotate, thereby driving the fork arm 102 to move, adjusting the position of the fork arm 102, and thus adjusting the distance between the three fork arms 102.

[0041] Based on the first embodiment, this utility model provides a second embodiment of a battery pack fork mechanism. The slide of the first linear guide rail 103 on the front crossbar 1011 and the rear crossbar 1013 is connected to the bottom of the fork arm 102 via the connecting block 3. The connecting block 3 is fixed with a guide rail clamp 4, which can lock the fork arm 102 after the position of the fork arm 102 is adjusted to prevent the fork arm 102 from moving.

[0042] Based on any of the above embodiments, this utility model provides a third embodiment of a battery pack fork lifting mechanism. The fork arm 102 can be an automatic telescopic fork arm of the brand Mias. The fork arm 102 includes a lower fork 1021 connected to a first linear guide rail 103. A middle fork 1022 is provided at the top of the lower fork 1021, and an upper fork 1023 is provided at the top of the middle fork 1022. Limiting blocks 1024 are fixed at both the front and rear ends of the upper fork 1023, and a rubber anti-slip pad 1025 is fixed between the two limiting blocks 1024 to prevent the battery pack from slipping.

[0043] Based on any of the above embodiments, this utility model provides a fourth embodiment of a battery pack fork mechanism, wherein a first magnetic grating ruler 210 is fixed on the slide of the second linear guide 202, which can identify the adjustment position of the fork arm 102.

[0044] Based on any of the above embodiments, this utility model provides a fifth embodiment of a battery pack fork mechanism, wherein the connecting block 3 and the four corners of the fork mounting bracket 101 are all fixed with first polyurethane buffers 5. The first polyurethane buffers 5 on the connecting block 3 can prevent the fork arms 102 from colliding when adjusting their position. The first polyurethane buffers 5 on the four corners of the mounting bracket are located at the inlet and outlet ends of the first linear guide rail 103 to prevent the fork arms 102 from disengaging from the first linear guide rail 103 when adjusting their position.

[0045] Based on the fifth embodiment, this utility model provides a sixth embodiment of a battery pack forklift mechanism 1, wherein the forklift mechanism 1 is driven by a lifting mechanism 6; the lifting mechanism 6 includes a lifting mounting frame 601, one end of the top middle crossbar of the lifting mounting frame 601 is fixed with a first steering device 602, the first steering device 602 has one input end and two output ends, and the other end is fixed with a second steering device 620, the second steering device 620 has one input end and one output end;

[0046] The first steering gear 602 is driven by the second drive motor 603. The first output end of the first steering gear 602 is connected to the input end of the second steering gear 620 via a rotating shaft 604. The second output end of the first steering gear 602 and the output end of the second steering gear 620 are both connected to ball screws 605. The lower end of the ball screws 605 is connected to the lifting mounting frame 601 via a bearing seat 606. The sliders 607 of the two ball screws 605 are respectively connected to the left and right ends of the forklift mounting frame 101.

[0047] The second drive motor 603 drives the first steering gear 602 to start, causing the rotating shaft 604 to rotate, which in turn drives the second steering gear 620 to start, causing the two ball screws 605 to rotate, which in turn causes the sliders 607 on the two ball screws 605 to move up and down, thereby driving the lifting mechanism 1 to rise and fall. The lifting mechanism 6 drives the lifting mechanism 1 to fall to the battery pack lifting position. The middle fork 1022 and the lower fork 1021 of the fork arm 102 extend so that the battery pack is located between the two limit blocks 1024. Then, the lifting mechanism 6 drives the lifting mechanism 1 to rise, which lifts the battery pack to the required height. The middle fork 1022 and the lower fork 1021 of the fork arm 102 drive the battery pack to retract and extend in the opposite direction, transferring the battery pack to the other side.

[0048] Based on the sixth embodiment, this utility model provides a seventh embodiment of a battery pack forklift mechanism. The top front crossbeam and the rear crossbeam of the lifting mounting frame 601 are each fixed with two second telescopic cylinders 608. The push rod end of the second telescopic cylinder 608 is connected to the forklift mounting frame 101. The second telescopic cylinder 608 is controlled by the air circuit to maintain its air pressure at a constant value, so that the forklift mechanism 1 is subjected to a constant force during the lifting or lowering process, thereby balancing the weight of the forklift mechanism 1 and the battery pack, reducing the pressure on the second drive motor 603, and extending its service life.

[0049] Based on the sixth embodiment, this utility model provides an eighth embodiment of the battery pack forklift mechanism. Two third linear guide rails 610 are fixed to the left and right vertical frames of the lifting mounting frame 601 via fixing plates 609. The slides of the third linear guide rails 610 are connected to the top of the forklift mounting frame 101 via connecting frames 611. The third linear guide rails 610 act as limit guides during the lifting and lowering of the forklift mounting frame 101, ensuring stable lifting and lowering. A hard limit bolt 612 is provided on the fixing plate 609 above the third linear guide rails 610. When the forklift mounting frame 101 rises beyond a preset value and continues to rise, it will encounter the hard limit bolt 612, preventing further rise and thus preventing damage to the mechanism and battery pack.

[0050] Based on the eighth embodiment, this utility model provides a ninth embodiment of a battery pack forklift mechanism. A support plate 613 is also fixed to the fixing plate 609, and multiple first wedge blocks 614 are longitudinally fixed to the support plate 613. A connecting seat 615 is fixed to the connecting frame 611, and the connecting seat 615 is fixed to a connecting plate 617 via a connecting shaft 616. A third telescopic cylinder 618 is fixed to the connecting plate 617. The push rod of the third telescopic cylinder 618 penetrates the connecting plate 617 and is fixed with a second wedge block 619 that engages with the first wedge blocks 614. The second wedge block 619 penetrates the connecting seat 615. When a sudden situation occurs during operation causing the forklift mounting frame 101 to fall, the third telescopic cylinder 618 pushes the second wedge block 619 to engage with it, thereby preventing the forklift mounting frame 101 from falling and protecting the safety of personnel and the mechanism.

[0051] Based on the sixth embodiment, this utility model provides a tenth embodiment of a battery pack forklift mechanism, wherein each of the four top corners of the lifting mounting frame 601 is fixed with a second polyurethane buffer 7, which can buffer the forklift mounting frame 101 when it falls.

[0052] The drive motor, telescopic cylinder, linear guide rail, guide rail clamp, magnetic scale, polyurethane buffer, steering gear, and fork arm in this utility model are all existing technologies, which are already clearly understood by those skilled in the art, and will not be described in detail here.

[0053] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application.
