Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a self-propelled precision positioning hanger for a body-in-white floor assembly. Background Technology

[0002] According to automotive terminology standards and textbook definitions, a body-in-white refers to a vehicle body that has been welded but not yet painted. The painted body-in-white, along with interior and exterior trim (including dashboard, seats, windshield, carpets, interior panels, etc.), electronic and electrical systems (audio, wiring harnesses, switches, etc.), chassis systems (including braking and suspension systems), and powertrain systems (including engine and transmission), constitutes the complete vehicle.

[0003] The lifting of the floor assembly of the automotive body-in-white is usually carried out in two ways: using movable hooks or fixed hooks.

[0004] In the existing technology, when using movable hooks to lift the existing body-in-white floor assembly, multiple fixed hooks need to be accurately placed at the lifting points of the floor assembly, which is difficult to operate and wastes a lot of time. When using fixed hooks, the operator must ensure the accurate placement of multiple fixed hooks at the same time. When there is insufficient space for the parts, the parts are very easy to collide with, resulting in damage and quality problems. Utility Model Content

A latching member for connecting the floor assembly is provided at the end of the first swing arm away from the first connecting rod and at the end of the second swing arm away from the third connecting rod. The latching member faces the floor assembly. A hinge member is also provided on the side of the first swing arm facing the first connecting rod and the side of the second swing arm facing the third connecting rod. The first swing arm and the second swing arm are hinged to the bottom of the support structure via the hinge member.

[0007] Furthermore, the positioning component includes a base plate structure, a plurality of anchor bolt structures disposed around the bottom of the base plate structure for connecting to the ground, and a plurality of support column structures disposed around the top of the base plate structure for connecting to the floor assembly.

[0008] Furthermore, two guide posts and two positioning posts are provided on both sides of the top of the base plate structure. A guide component is provided on the top of the guide post, and a connection hole for connecting the support structure is provided on the top of the positioning post.

[0009] Furthermore, two guide legs adapted to the guide member and two positioning legs adapted to the connecting hole are provided at the bottom of the support structure. A guide strip adapted to the guide member is provided at the bottom of the guide legs, and a positioning pin adapted to the connecting hole is provided at the bottom of the positioning legs.

[0010] Furthermore, the hoisting assembly includes a guide rail, a sliding assembly slidably disposed on the guide rail, and a lifting assembly disposed on the sliding assembly. The sliding assembly includes a crossbeam fastened to the waist of the guide rail, a limiting member connected to the top of the crossbeam, support blocks disposed at both ends of the crossbeam, guide wheels connected to both sides of the support blocks and slidably disposed on the bottom sidewall of the guide rail, a driven wheel connected to the top of the support block and slidably disposed on the bottom of the guide rail, a drive structure disposed on one side of the support block structure, and a drive wheel connected to the output end of the drive structure and slidably disposed on the bottom of the rail. A sensor switch for sensing the limiting member is disposed on the top of the guide rail, and the drive wheel is disposed between the two guide wheels.

[0011] Furthermore, the lifting assembly includes support frames connected to both sides of the bottom of the crossbeam and a crane structure connected to the center of the bottom of the crossbeam, with the output end of the crane structure passing through the support frames and connected to the lifting ring structure.

[0012] Furthermore, multiple guide sleeves are provided on the outside of the support frame structure, and a guide rod is slidably arranged inside the guide sleeve. A retaining ring is provided on the top of the guide rod, and the diameter of the retaining ring is larger than the diameter of the inner hole of the guide sleeve.

[0015] Furthermore, a counterweight is also provided on the support structure.

[0016] The beneficial effects of this utility model are as follows: By setting a linkage structure on the support structure, the floor assembly is connected through the linkage structure, and then the floor assembly is lifted by the lifting assembly. This eliminates the need to use multiple fixing hooks to lift the floor assembly, reducing operational difficulty and saving time. Specifically, by rotating the pivot clockwise, the pivot drives the swinging component to rotate, causing the first connecting rod at the hinged end to move away from the pivot. This, in turn, causes the first swing arm hinged to the first connecting rod to rotate counterclockwise around the hinge, thus connecting the buckle on the first swing arm to the floor assembly. At the same time, the pivot also drives the second connecting rod at the hinged end to move away from the pivot. This causes the second connecting rod to drive the third connecting rod hinged to the second connecting rod, which in turn drives the second swing arm hinged to both ends of the third connecting rod to rotate clockwise around the hinge, thus connecting the buckle on the second swing arm to the floor assembly. This eliminates the need to use multiple fixing hooks to lift the floor assembly, reducing operational difficulty and saving time. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 5 The self-propelled precision positioning hanger for the body-in-white floor assembly in this embodiment of the present invention includes a positioning component 10 for placing the floor assembly 40, a clamping component 20 for connecting the floor assembly 40, and a lifting component 30 for moving the clamping component 20. The clamping component 20 includes a support structure 21, a lifting ring structure 22 disposed at the top center of the support structure 21 for connecting the lifting component 30, and a connecting rod structure 23 threadedly connected to the support structure 21 for connecting the floor assembly 40. The connecting rod structure 23 includes a first bearing seat 231 threadedly connected to one side of the lifting ring structure 22, a second bearing seat 232 threadedly connected to the top of the support structure 21, a rotating shaft 233 rotatably disposed at both ends on the first bearing seat 231 and the second bearing seat 232 respectively, a swing member 234 fixedly connected to the end of the rotating shaft 233 facing the first bearing seat 231, and hinged to the support structure 21. The swing member 234 has a first connecting rod 235 and a second connecting rod 236 at both ends, a first swing arm 237 hinged to the end of the first connecting rod 235 away from the swing member 234, a third connecting rod 238 hinged to the end of the second connecting rod 236 away from the swing member 234, and a second swing arm 239 hinged to both ends of the third connecting rod 238. A latching member 240 for connecting the floor assembly 40 is provided at the end of the first swing arm 237 away from the first connecting rod 235 and at the end of the second swing arm 239 away from the third connecting rod 238. The latching member 240 is positioned towards the floor assembly 40. A hinge member 241 is also provided on the side of the first swing arm 237 facing the first connecting rod 235 and the side of the second swing arm 239 facing the third connecting rod 238. The first swing arm 237 and the second swing arm 239 are hinged to the bottom of the support structure 21 via the hinge member 241.

[0029] Understandably, by rotating the pivot 233 clockwise, the pivot 233 drives the swing member 234 to rotate, causing the swing member 234 to drive the first connecting rod hinged to one end of the swing member 234 to move away from the swing member 234. This, in turn, causes the first swing arm 237 hinged to the first connecting rod 235 to rotate counterclockwise around the hinge member 241. Consequently, the latch 240 on the first swing arm 237 is connected to the floor assembly 40. At the same time, the swing member 234 also drives the first swing member 234 to rotate counterclockwise around the hinge member 241. The second link 236 at one end of 34 moves away from the swing member 234, causing the second link 236 to drive the third link 238 hinged to the second link 236. In turn, the third link 238 drives the second swing arm 239 hinged to both ends of the third link 238 to rotate clockwise around the hinge member 241. This causes the buckle member 240 on the second swing arm 239 to connect to the floor assembly 40, so that the floor assembly does not need to be hoisted using multiple fixing hooks, which reduces the difficulty of operation and saves time.

[0030] Furthermore, the positioning component 10 includes a base plate structure 11, a plurality of anchor bolt structures 12 disposed around the bottom of the base plate structure 11 for connecting to the ground, and a plurality of support column structures 13 disposed around the top of the base plate structure 11 for connecting to the floor assembly 40.

[0031] Furthermore, two guide posts 14 and two positioning posts 15 are provided on both sides of the top of the base plate structure 11. A guide member 16 is provided on the top of the guide post 14, and a connection hole 17 for connecting the support structure 21 is provided on the top of the positioning post 15.

[0032] Furthermore, two guide legs 242 adapted to the guide member 16 and two positioning legs 243 adapted to the connecting hole 17 are provided at the bottom of the support structure 21. A guide strip 244 adapted to the guide member 16 is provided at the bottom of the guide legs 242, and a positioning pin 245 adapted to the connecting hole 17 is provided at the bottom of the positioning legs 243.

[0033] Understandably, the anchor bolt structure 12 allows the positioning component 10 to be fixed to the ground and its level to be adjusted; the base plate structure 11 and the multiple support column structures 13 arranged around the top of the base plate structure enable the placement and positioning of the floor assembly 40; and the two guide columns 14 and two positioning columns 15 arranged on the top of the base plate structure 11 allow the support structure 21 to descend through the bottom of the guide legs 242. The guide strip 244 is initially positioned by cooperating with the guide member 16 at the top of the guide post 14, and then precisely positioned by cooperating with the positioning pin 245 at the bottom of the positioning foot 243 and the connecting hole 17 at the top of the positioning post 15. This allows the buckle member 240 at the bottom of the first swing arm 237 and the second swing arm 239 to be precisely connected to the floor assembly 40, solving the problem of insufficient space in the floor assembly 40 and avoiding collisions with the floor assembly 40 during hoisting, which could damage the floor assembly 40 and cause quality problems.

[0034] Furthermore, the hoisting assembly 30 includes a guide rail 31, a sliding assembly 32 slidably disposed on the guide rail 31, and a lifting assembly 33 disposed on the sliding assembly 32. The sliding assembly 32 includes a crossbeam 321 fastened to the rail web of the guide rail 31, a limiting member 322 connected to the top of the crossbeam 321, support blocks 323 disposed at both ends of the crossbeam 321, guide wheels 324 connected to both sides of the support blocks 323 and slidably disposed on the bottom sidewall of the guide rail 31, driven wheels 325 connected to the top of the support blocks 323 and slidably disposed on the bottom of the guide rail 31, a drive structure 326 disposed on one side of the support block structure 323, and a drive wheel 327 connected to the output end of the drive structure 326 and slidably disposed on the bottom of the rail. A sensor switch 328 for sensing the limiting member 322 is provided at the top of the guide rail 31, and the drive wheel 327 is disposed between the two guide wheels 324.

[0035] Furthermore, the lifting assembly 33 includes a support frame 331 connected to both sides of the bottom of the crossbeam 321 and a crane structure 332 connected to the center of the bottom of the crossbeam 321. The output end of the crane structure 332 passes through the support frame 331 and is connected to the lifting ring structure 22.

[0036] Understandably, the drive structure 326 and the drive wheel 327 slidably disposed on the bottom of the rail connected to the output end of the drive structure 326 generate friction between the drive wheel 327 and the guide rail 31, thereby driving the driven wheel 325 and realizing movement on the guide rail 31. The four guide wheels 324 maintain the stability of movement, and the two inductive switches 328 prevent the present invention from moving beyond the travel range on the guide rail 31.

[0037] Furthermore, a plurality of guide sleeves 333 are provided on the outside of the support frame structure 331, and a guide rod 334 is slidably arranged inside the guide sleeve 333. A retaining ring 335 is provided on the top of the guide rod 334, and the diameter of the retaining ring 335 is larger than the diameter of the inner hole of the guide sleeve 333.

[0038] Furthermore, a support seat 246 for abutting against the guide rod 334 is also provided on the support structure 21.

[0039] Understandably, by setting the guide sleeve 333, the guide rod 334 slidably disposed in the guide sleeve, and the support seat 246 for abutting against the guide rod 334, the lifting assembly 33 can increase axial stability during lifting by cooperating with the guide sleeve 333, the guide rod 334, and the support seat 246.

[0040] Furthermore, a drive assembly 25 for driving the rotating shaft 233 is also provided on the support structure 21. The drive assembly 25 includes a base 251 threadedly connected to the support structure 21, a pull rod 252 hinged to the base 251, a ratchet structure 253 hinged to the end of the rotating shaft 233 facing the second bearing seat 232, a fourth link 254 hinged to the end of the ratchet structure 253 away from the rotating shaft 233, a fifth link 255 hinged to the end of the fourth link 254 away from the ratchet structure 253, and a V-shaped plate 256 hinged to the end of the fifth link 255 away from the fourth link 254. The end of the V-shaped plate 256 away from the fifth link 255 is hinged to the pull rod 252.

[0041] Understandably, by pushing the pull rod 252 toward the ratchet structure 253, the V-shaped plate 256, the fifth link 255, and the fourth link 254 move toward the ratchet structure 253, causing the fourth link 254 to push the ratchet structure 253 to rotate the shaft 233 clockwise; by pulling the pull rod 252 away from the ratchet structure 253, the V-shaped plate 256, the fifth link 255, and the fourth link 254 move toward the base 251, causing the fourth link 254 to pull the ratchet structure 253 to rotate the shaft 233 counterclockwise.

[0042] Furthermore, a counterweight 26 is also provided on the support structure 21.

[0043] Understandably, by setting the counterweight 26 on the support structure 21, the center of gravity of the clamp assembly 20 can be adjusted by adjusting the weight of the counterweight, thereby ensuring that the center of gravity of the floor assembly 40 and the clamp assembly 20 are on the same vertical line as the lifting assembly 33 during hoisting.

[0044] In summary, the self-propelled precision positioning hoist for the body-in-white floor assembly in the above embodiments of this utility model, by setting a linkage structure on the support structure, connects the floor assembly through the linkage structure, and then lifts the floor assembly through the hoisting assembly, eliminating the need to use multiple fixed hooks to hoist the floor assembly, thus reducing operational difficulty and saving time. Specifically, by rotating the rotating shaft clockwise, the rotating shaft drives the swinging component to rotate, causing the swinging component to move the first connecting rod at the hinged end away from the swinging component, thereby causing the first swing arm hinged to the first connecting rod to rotate counterclockwise around the hinged component, thus connecting the buckle on the first swing arm to the floor assembly. At the same time, the swinging component also causes the second connecting rod at the hinged end to move away from the swinging component, causing the second connecting rod to drive the third connecting rod hinged to the second connecting rod, thereby causing the second swing arm hinged at both ends of the third connecting rod to rotate clockwise around the hinged component, thus connecting the buckle on the second swing arm to the floor assembly. This eliminates the need to use multiple fixed hooks to hoist the floor assembly, reducing operational difficulty and saving time.
