[0040] Example 1:

[0041] like Figures 1-10 As shown, a quick-release vehicle transfer device includes:

[0042] 1. Hydraulic carriage; 2. Sleeve shaft; 3. Fixed frame; 4. Movable frame; and 5. Movable support roller assembly.

[0043] A frame 12 is fixedly mounted on the front fork 11 of the hydraulic vehicle 1;

[0044] The sleeve shaft 2 is rotatably mounted on the frame 12, and a turntable 21 that rotates synchronously with it is mounted on the sleeve shaft 2;

[0045] The fixed frame 3 is mounted on the turntable 21, and the movable frame 4 with retractable and extendable configuration is symmetrically arranged on both sides of the fixed frame 3;

[0046] The movable support roller group 5 is arranged in a one-to-one correspondence with the movable frame 4. The movable support roller group 5 and the movable frame 4 are detachably arranged, and the movable support roller group 5 supports the front wheels of the vehicle.

[0047] Specifically, the platform 12 is plate-shaped and is connected to the front fork 11 by screws. The turntable 21 rotates relative to the hydraulic carriage 1 through the sleeve shaft 2. The fixed frame 3 is mounted on the turntable 21 from above. The movable frame 4 is symmetrically and telescopically arranged on both sides of the fixed frame 3, corresponding to the two sets of front wheels of the car. The movable support roller group 5 is connected to the movable frame one by one to lift the front wheels of the car.

[0048] In use, the hydraulic carriage 1, along with the fixed frame 3 and the movable frame 4, is inserted under the car chassis. Then, the movable frame 4 is extended to both sides, passing over the front wheels of the car. The movable support roller group 5 is then assembled and connected with the movable frame 4. After that, the movable frame 4 is retracted, so that the movable support roller group 5 is retracted to the front wheels. Then, the movable support roller group 5 is adjusted to support the front wheels.

[0049] In a preferred embodiment, the fixing frame 3 is arranged in a U-shape, and two sets of guide rods 31 are arranged in parallel on the fixing frame 3, and the movable frame 4 is slidably arranged on the guide rods 31.

[0050] Furthermore, the movable frame 4 is U-shaped and includes a sleeve 41 and a tube 42. The sleeve 41 is inserted through the guide rod 31 and slides along the guide rod 31. The tube 42 is inserted into both ends of the sleeve 41 in the axial direction and is telescopically arranged relative to the sleeve 41.

[0051] To prevent the sleeve 42 from falling off the sleeve 41, the sleeve 42 is provided with a waist groove 421 that is parallel to the sleeve 41. The sleeve 41 is provided with a limiting pin 411 that cooperates with the waist groove 421. By utilizing the cooperation between the waist groove 421 and the limiting pin 411, the sleeve 42 is prevented from falling off while still being able to move freely.

[0052] Meanwhile, in order to automatically adjust the sliding of the movable frame 4 along the guide rod 31, a lead screw module 6 is provided on the turntable 21 to drive the movable frame 4 to retract and extend. The lead screw module 6 includes a mounting box 60, a lead screw 61, a lead screw nut 62, a bevel gear set 63, and a rocker handle 64. The mounting box 60 is fixedly installed on the turntable 21. The lead screw 61 passes through the mounting box 60 and is perpendicular to the sleeve 41. The two ends of the lead screw 61 are respectively provided with positive and negative threads. The lead screw nut 62 is installed on the sleeve 41 and is threadedly engaged with the lead screw 61. The bevel gear set 63 is located at the center of the lead screw 61. The rocker handle 64 passes through the mounting box 60 and drives the lead screw 61 to rotate through the bevel gear set 63.

[0053] Specifically, the crank 64 drives the bevel gear set 63 to operate, and the bevel gear set 63 drives the lead screw 61 to rotate. When the lead screw 61 rotates, the positive and negative threads at both ends of the lead screw 61 cooperate with the lead screw nut 62, so that the lead screw nut 62 can move on the lead screw 61, thereby driving the movable frame 4 to move to both sides or to the center of the hydraulic car 1.

[0054] Meanwhile, the movable support roller group 5 includes a telescopic tube unit 51, support rollers 52, rollers 53 and a control unit 54. The telescopic tube unit 51 includes two sets of square tubes 511 that are nested and telescopically arranged. Two sets of support rollers 52 are arranged in parallel. The support rollers 52 are respectively located at the two axial ends of the telescopic tube unit 51. The rollers 53 are respectively located below the two axial ends of the support rollers 52. The control unit 54 drives the support rollers 52 to move closer or further apart from each other.

[0055] Furthermore, the control unit 54 includes a lead screw shaft 541, a nut seat 542, and a crank handle 543. The lead screw shaft 541 is arranged parallel to the telescopic tube unit 51, and one end of the lead screw shaft 541 is rotatably connected to any of the support rollers 52. The nut seat 542 is sleeved on the lead screw shaft 541 and is fixedly connected to a square tube 511 connected to another support roller 52. The crank handle 543 is connected to the lead screw shaft 541 and drives the lead screw shaft 541 to rotate.

[0056] Furthermore, the support roller 52 is detachably connected to the sleeve 42. The end of the support roller 52 is provided with a square tube joint 521 that is sleeved with the sleeve 42. The square tube joint 521 is provided with a through hole 522. The sleeve 42 is provided with a mating hole 422 that corresponds to the through hole 522. A pin 523 is inserted into the through hole 522 and the mating hole 422 to connect the square tube joint 521 and the sleeve 42.

[0057] Specifically, the support roller 52 of the movable support roller group 5 is initially not connected to the sleeve 42. After the hydraulic carriage 1 extends under the car chassis, the movable frame 4 extends outward from under the car chassis and then connects the support roller 52 to the sleeve 42. After the connection is completed, the movable frame 4 retracts, bringing the support roller 52 to the underside of the car chassis. At the same time, the two sets of support rollers 52 are located on the front and rear sides of the car's front wheels, respectively. Then, the control unit 54 controls the support rollers 52 to move closer together, lifting the car's front wheels. Since the spacing between the support rollers 52 can be adjusted at will, the movable support roller group 5 achieves the effect of being suitable for all sizes of tires and adapting to various car models.

[0058] When the support rollers 52 are brought closer together, specifically, the crank handle 543 is first turned, which drives the lead screw shaft 541 to rotate. Since the lead screw shaft 541 and the nut seat 542 are respectively located on the two sets of support rollers 52, that is, the lead screw shaft 541 is connected to the square tube 511 of one set of support rollers 52 through the support rollers 52, and the nut seat 542 is connected to the support rollers of another set through the square tube 511 of the other set of support rollers 52, when the lead screw shaft 541 rotates, the threaded engagement between the lead screw shaft 541 and the nut seat 542 will cause the two sets of support rollers 52 to move closer or further apart. Moreover, the threaded fittings of the lead screw shaft 541 and the nut seat 542 will achieve self-locking. After the support rollers 52 support the front wheel, the support rollers 52 will not separate under force and can stably support the tire.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
