Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] See also Figure 1 In this embodiment, an adjustable tire lift includes a support frame 1, a stabilizing frame 2 is fixed to the right end of the upper surface of the support frame 1, a moving mechanism 3 is provided on the lower surface of the support frame 1 for facilitating the movement of the support frame 1, an adjusting mechanism 4 is provided on the upper surface of the stabilizing frame 2 for lifting wheels and adapting to wheels of different sizes, and a handle 5 is fixed to the right side of the support frame 1.
[0032] In this embodiment, a counterweight is fixed to the upper surface of the support frame 1 to improve the stability of the support frame 1 .
[0033] See also Figures 2 to 3In order to adapt to tires of different sizes, the adjustment mechanism 4 in this embodiment includes a first motor 41, a threaded rod 42, a fixing block 43, a support fork 44, a second motor 45, a bidirectional screw 46, two screw sleeves 47, two connecting blocks 48 and two positioning clamps 49. The first motor 41 is fixed to the upper surface of the stabilizing frame 2, and the threaded rod 42 is rotatably connected between the inner top wall and the inner bottom wall of the stabilizing frame 2 on the opposite side. The output shaft of the first motor 41 passes through the inner top wall of the stabilizing frame 2 and extends to the inner cavity of the stabilizing frame 2 and is fixed to the threaded rod 42. The fixing block 43 is threadedly connected to the threaded rod 42. The support fork 44 is fixed to the left side of the fixing block 43. The controller synchronously starts the four first motors 4 1. The output shaft of the first motor 41 rotates to drive the threaded rod 42 to rotate. The rotation of the threaded rod 42 causes the fixed block 43 threadedly connected to its surface to move upward, thereby adjusting the support fork 44 to a suitable height. The second motor 45 is fixed to the left end of the inner wall of the support fork 44. The bidirectional screw 46 is fixed to the output shaft of the second motor 45. The screw sleeve 47 is threadedly connected to the bidirectional screw 46. The connecting block 48 is fixed to the right side of the screw sleeve 47. The second motor 45 is started, and the output shaft of the second motor 45 rotates, thereby driving the bidirectional screw 46 to rotate. The rotation of the bidirectional screw 46 causes the two screw sleeves 47 threadedly connected to its surface to move relative to each other, thereby driving the two connecting blocks 48 to move relative to each other.
[0034] In this embodiment, mounting blocks are fixed to the top and bottom of the front and back sides of the stabilizer frame 2, and a limit rod is fixed between the opposite sides of the two mounting blocks. The right sides of the front and rear ends of the support fork 44 both make linear up and down motions on the outer surface of the limit rod.
[0035] Among them, a height sensor is fixed to the right end of the lower surface of the supporting fork 44. The height sensor can monitor the height of each wheel in real time to ensure that the four wheels always remain balanced during the lifting process. The cross-sectional shape of the supporting fork 44 is U-shaped, and a groove is provided on the upper surface of the supporting fork 44. The positioning clamp 49 is arranged in the inner cavity of the groove. The right side of the connecting block 48 passes through the groove and extends to the inner cavity of the groove and is fixed to the positioning clamp 49. The upper surface of the positioning clamp 49 is provided with an arc surface, and a rubber layer is fixed on the upper surface of the arc surface. A through hole is provided on the inner top wall of the groove. The movement of the connecting block 48 drives the two positioning clamps 49 to move relative to each other. At this time, the slider fixed on the right side of the positioning clamp 49 moves in the inner cavity of the slide groove, which can limit the movement of the positioning clamp 49. The relative movement of the two positioning clamps 49 can clamp the front and rear sides of the wheel.
[0036] In addition, a slide groove is opened on the right side of the groove, and a slider is fixed to the right side of the positioning clamp 49. The slider moves back and forth linearly in the inner cavity of the slide groove. A positioning strip is fixed to the inner bottom wall of the support fork 44, and a positioning block is fixed to the lower surface of the screw sleeve 47. The positioning block moves back and forth linearly in the inner cavity of the positioning strip.
[0037] It should be noted that the electrical components appearing in the text are all electrically connected to the controller and the power supply and are all conventionally known devices. This application will not go into too much detail. The controller can be a conventionally known device such as a computer that plays a controlling role. The control circuit of the controller can be implemented by simple programming by technicians in this field.
[0038] See also Figure 4 The movable plate 32 is fixed between the two opposite sides of the two gear plates 35, and the universal wheels 36 are rotatably mounted on the lower surface of the movable plate 32. The gear plate 35 drives the movable plate 32 to move downward. The movement of the movable plate 32 drives the three universal wheels 36 to move downward until the universal wheels 36 pass through the fixing holes and touch the ground, thereby pushing the handle 5 to move the support frame 1.
[0039] Among them, fixing holes are opened at both ends of the lower surface of the support plate 31, and the size of the inner cavity of the fixing hole is adapted to the size of the universal wheel 36. One of the universal wheels 36 is rotatably installed in the middle of the left end of the lower surface of the movable plate 32, and the other two universal wheels 36 are rotatably installed at the right end of the lower surface of the movable plate 32.
[0040] In this embodiment, clamping rods are fixed to the left and right ends of the inner top wall and the inner bottom wall of the support plate 31 on the side opposite to each other, and the movable plate 32 is slidably connected to the clamping rods.
[0041] It should be noted that inner rods are fixed to the left and right ends of the inner top wall and the inner bottom wall of the support plate 31 on the opposite side. The inner rods are slidably connected to the tooth plate 35 to limit the movement of the tooth plate 35.
[0042] The working principle of the above embodiment is:
[0043] (1) When lifting the wheels of the car, first, the four wheels of the car are respectively located in the inner cavity of the four support forks 44, and then the second motor 45 is started. The output shaft of the second motor 45 rotates, thereby driving the bidirectional screw 46 to rotate. The rotation of the bidirectional screw 46 causes the two screw sleeves 47 threadedly connected to its surface to move relative to each other, thereby driving the two connecting blocks 48 to move relative to each other. The movement of the connecting block 48 drives the two positioning clamps 49 to move relative to each other. At this time, the slider fixed on the right side of the positioning clamp 49 moves in the inner cavity of the slide groove, which can limit the movement of the positioning clamp 49. The relative movement of the two positioning clamps 49 can clamp the front and rear sides of the wheel. Then the controller starts the four first motors 41 synchronously. The output shaft of the first motor 41 rotates to drive the threaded rod 42 to rotate. The rotation of the threaded rod 42 causes the fixed block 43 threadedly connected to its surface to move upward, thereby adjusting the support fork 44 to a suitable height. The height sensor can monitor the height of each wheel in real time to ensure that the four wheels always remain balanced during the lifting process.
[0044] (2) In order to facilitate the movement and positioning of the support frame 1, when it is necessary to move, the third motor 33 is started, and the output shaft of the third motor 33 rotates to drive the rotating gear 34 to rotate. The rotation of the rotating gear 34 causes the toothed plate 35 meshed with it to move downward. At this time, the toothed plate 35 slides downward on the outer surface of the inner rod and drives the movable plate 32 to move downward. The movement of the movable plate 32 drives the three universal wheels 36 to move downward until the universal wheels 36 pass through the fixing holes to the ground, thereby being able to push the handle 5 to move the support frame 1.
