[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0044] Example 1:

[0045] As attached Figure 1 To the attached Figure 13As shown, the present invention provides a quick disassembly and assembly device for automobile tires, comprising a base plate 1, with wheels 101 for movement installed at the four corners of the bottom thereof, a dovetail groove 102 and a dovetail groove 2 103 opened on the top, a slider 102 slidably connected to the inside of the dovetail groove 102, a lifting mechanism 3 arranged on the upper side of the slider 102 for lifting the automobile, a movable frame 4 arranged vertically on the top of the base plate 1, a fixing mechanism 5 arranged in the movable frame 4, and two sets of cylinders 20 6 installed on the bottom of the base plate 1, and the piston rods of the cylinders 20 6 extend to the bottom plate. 1 and fixed to the bottom of the movable frame 4, and is used to cooperate with the fixing mechanism 5 to stably clamp the tire. The disc 7 is arranged on the upper side of the fixing mechanism 5, and a plurality of ratchet wrenches 8 for removing the tire bolts are provided on the rear side. The adjustment mechanism 9 is arranged on the front side of the disc 7 for aligning the ratchet wrenches 8 with the tire bolts. The rotation mechanism 10 is arranged on the rear side of the disc 7 for driving the ratchet wrench 8 to rotate. The removal mechanism 11 is arranged between the rotation mechanism 10 and the ratchet wrench 8 for quickly replacing the adapted ratchet wrench 8.

[0046] As can be seen from the above, when using the device, the bottom plate 1 is first moved by the wheel 101 until the jacking mechanism 3 moves the vehicle to the jacking position. At this time, the jacking mechanism 3 is at the leftmost side of the dovetail groove 102. Then, the vehicle is jacked up by the jacking mechanism 3 to lift the corresponding tire to be removed from the ground. Then, the bottom plate 1 is moved toward the tire by the wheel 101. The jacking mechanism 3 slides to the right along the dovetail groove 102 through the slider 2 until the fixing mechanism 5 is directly under the tire. The cylinder 2 6 is opened and the movable frame 4 is driven to rise, so that the tire is in the middle of the fixing mechanism 5. The tire is fixed to the tire by the fixing mechanism 5. For effective fixation, since the connecting bolts between the tire steel and the connecting assembly are distributed circumferentially, the ratchet wrenches 8 are then rotated to correspond one-to-one with the bolts through the adjusting mechanism 9, and the ratchet wrenches 8 are effectively inserted into the outside of the bolts. The ratchet wrenches 8 are then rotated through the rotating mechanism 10 to disengage the bolts from the tire steel and the connecting assembly. The tire is then removed through the fixing mechanism 5, and the above steps are reversed to remove the device. It is worth noting that when the ratchet wrench 8 is of a different model from the bolt, the ratchet wrench 8 can be quickly replaced through the disassembly mechanism 11, thereby further improving the applicability of the device.

[0047] Example 2:

[0048] As attached Figure 2 To the attached Figure 4As shown, this embodiment is basically the same as the previous embodiment, except that the jacking mechanism 3 includes a fixed plate 301 fixedly connected to the top of the slider 2, and sliding members 302 are fixedly installed on opposite sides of the top of the fixed plate 301. The outer sides of the sliding members 302 are rotatably connected to the rotating rod 1 303, and the middle part of the rotating rod 1 303 is rotatably connected to the rotating rod 2 304. The top of the fixed plate 301 is also fixedly connected to a fixing member 305, and the rotating rods 2 304 on both sides are rotatably connected to the fixing member 305. Two groups of cylinders 1 306 are rotatably installed above the fixing member 305, and a connecting plate 307 is fixedly connected between the rotating rods 1 303 on both sides. The piston rods of the two groups of cylinders 1 306 are rotatably connected to the connecting plate 307. The sliding member 302 includes a fixed rail 3021 fixedly connected to the top of the slider 2, and the outer surface of the fixed rail 3021 is slidably connected to two groups of sliding blocks 3022. The tops of the two groups of sliding blocks 3022 are fixedly connected to the supporting slide 3023, and the tops of the supporting slide 3023 are fixedly connected to the fixing frame 3024. The fixing frame 3024 is rotatably connected to the rotating rod 303. The ends of the rotating rods 303 on both sides away from the sliding member 302 are rotatably connected to the lifting plate 308. The bottom of the lifting plate 308 is also fixedly connected to the two groups of sliding members 302, and the ends of the rotating rods 2 304 away from the fixed member 305 are rotatably connected to the sliding member 302. The top of the lifting plate 308 is fixedly connected to the anti-sliding block 309.

[0049] As can be seen from the above, when the vehicle is lifted, the two groups of cylinders 1 306 are turned on, and the two groups of cylinders 1 306 drive the connecting plate 307 to move, thereby driving the rotating rods 1 303 on both sides to rotate. Since the rotating rod 1 303 is rotatably connected with the rotating rod 2 304, the rotating rods 1 303 and the rotating rods 2 304 are driven to rotate synchronously. One end of the two groups of rotating rods 1 303 and the rotating rod 2 304 drives the two groups of sliding blocks 1 3022 to slide on the outer surface of the fixed rail 3021 through the fixing frame 3024 and the supporting slide plate 3023, and then the lifting plate 308 is stably raised through the fixing frame 3024, so that the vehicle is lifted and lowered through the anti-sliding block 309, so that the tire on the corresponding side is lifted off the ground.

[0050] Example 3:

[0052] As can be seen from the above, cylinder 2 6 drives the movable frame 4 to rise, so that the tire is in the middle of the fixing mechanism 5, and then the stepper motor 1 502 is turned on. The stepper motor 1 502 drives the double-headed screw 501 to rotate, and the two sets of guide rods 503 are used to guide the sliding blocks 2 504 on both sides to approach each other, so that the tire is clamped by the resistance members 505 on both sides.

[0053] Example 4:

[0054] As attached Figure 7 As shown, this embodiment is basically the same as the previous embodiment, with the difference that the adjustment mechanism 9 includes a threaded rod 901 rotatably connected to the inside of the second dovetail groove 103, a stepper motor 902 is fixedly installed on the front side of the base plate 1, the output end of the second stepper motor 902 extends to the inside of the second dovetail groove 103, and is fixedly connected to one end of the threaded rod 901, the outer side of the threaded rod 901 is threadedly connected to a sliding plate 903, the sliding plate 903 slides in the second dovetail groove 103, a stepper motor 904 is fixedly installed on the front side of the sliding plate 903, the output end of the stepper motor 904 extends to the rear side of the sliding plate 903, and is fixedly connected to the disk 7.

[0055] As can be seen from the above, when the ratchet wrench 8 is inserted into the outside of the bolt, the stepper motor 3 904 is first turned on, and the stepper motor 3 904 drives the disc 7 to rotate, so that the ratchet wrenches 8 revolve to the position corresponding to the bolt, and then the stepper motor 2 902 is turned on, and the stepper motor 2 902 drives the threaded rod 901, and the threaded rod 901 drives the sliding plate 903 to slide backward along the dovetail groove 2 103, so that the ratchet wrenches 8 are all inserted into the outside of the bolt.

[0056] Example 5:

[0057] As attached Figure 8As shown, this embodiment is basically the same as the previous embodiment, except that the rotating mechanism 10 includes a cylinder 1001 that rotates equidistantly in a circle on the rear side of the disc 7, and the outer sides of the cylinders 1001 are fixedly connected with rotating rollers 1002. Several rotating rollers 1002 are connected in pairs through belts 1003. The outer side of one of the cylinders 1001 is fixedly connected with a matching gear 1004, and the outer side of the matching gear 1004 is meshed with a driving gear 1005. A stepper motor 4 1006 is fixedly installed on the rear side of the disc 7, and the output end of the stepper motor 4 1006 is fixed to the driving gear 1005.

[0058] As can be seen from the above, when several ratchet wrenches 8 are rotated, the stepper motor four 1006 is turned on, and the stepper motor four 1006 drives the active gear 1005 to rotate, drives the matching gear 1004 to rotate, and the matching gear 1004 rotates to drive one group of columns 1001 to rotate, and then drives all the columns 1001 to rotate through the rotating roller 1002 and the belt 1003, thereby driving the ratchet wrench 8 to loosen the bolts.

[0059] Example 6:

[0060] As attached Figure 9 To the attached Figure 13 As shown, this embodiment is basically the same as the previous embodiment, except that the disassembly mechanism 11 includes a connecting member 1101 and a connecting member 2 1103, the connecting member 1101 is welded to the end of the column 1001 away from the disc 7, the outer surface of the connecting member 1101 is evenly distributed with a plurality of concave blocks 1102, the connecting member 2 1103 is fixed to the ratchet wrench 8, the outer surface of the connecting member 2 1103 is evenly distributed with a plurality of concave blocks 2 1104, the concave blocks 1102 and the concave blocks 2 1104 are staggered, the outer side of the connecting member 1101 is fixedly connected to a fixed block 1105, and the opposite sides of the fixed block 1105 are rotatably connected to a rotating arc plate 1107 and a rotating arc plate 2 1107 respectively through a hinge frame 1106. 08.

[0061] As can be seen from the above, when replacing the ratchet wrench 8, first hold the clamping block 1114 and slide the telescopic member 1113 along the through groove 1109 to disengage the telescopic member 1113 from the clamping groove 1115, then rotate the rotating arc plate 1107 and the rotating arc plate 2 1108 to disengage the concave block 1102 and the concave block 2 1104 to remove the ratchet wrench 8. Similarly, the ratchet wrench 8 of the model adapted to the bolt is disengaged from the concave block 2 1104 on the outside through the connecting piece 2 1103. The two parts are staggered with the recessed block 1102, and then the clamping block 1114 is held to retract the telescopic part 1113 into the through groove 11, and then the rotating arc plate 1107 and the rotating arc plate 2 1108 are rotated so that both are stuck in the grooves of the recessed block 1102 and the recessed block 2 1104, and then the clamping block 1114 is released, and the slider 2 1112 is pushed by the spring 1111 to make the connecting part 2 1103 stuck in the clamping groove 1115, thereby completing the quick replacement of the ratchet wrench 8.
