[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a steering wheel car lifting mechanism, including a steering wheel car body 1. An adjustment groove is provided inside the steering wheel car body 1. A bidirectional screw 2 is rotatably connected inside the adjustment groove. An adjustment ring 3 is drivenly connected to the outer surface of the bidirectional screw 2. A connecting seat is provided on the outer surface of the adjustment ring 3. A support plate 4 is rotatably connected inside the connecting seat. A fixed seat 5 is provided at the end of the support plate 4 away from the connecting seat. A lifting platform 6 is provided on the upper surface of the fixed seat 5. An adjustment chamber is provided inside the lifting platform 6. A first electric push rod 7 is provided inside the adjustment chamber. The output end of the electric push rod 7 is provided with a connecting plate 8. The connecting plate 8 has a connecting through hole. A limit slide rod 9 is slidably connected inside the connecting through hole. A guide slide rod is provided on the lower surface of the connecting plate 8. A connecting ring 10 is provided on the outer surface of the guide slide rod. The connecting ring 10 is located at the lower end of the limit slide rod 9. A first spring 11 is provided on the outer surface of the connecting ring 10. A limit piece is provided at the end of the first spring 11 away from the connecting ring 10. The limit piece is located on the guide slide rod. A limit through hole is provided inside the lifting platform 6. The limit slide rod 9 is slidably connected inside the limit through hole.

[0025] Specifically, the rotation of the bidirectional screw 2 drives the adjusting ring 3 to rotate on the bidirectional screw 2, thereby driving the support plate 4 to rotate, causing the lifting platform 6 to slide up along the limiting slide plate 12, thus raising and lowering the working surface of the steering wheel vehicle; before placing the item, the first electric push rod 7 is controlled to extend, causing the connecting plate 8 and the limiting slide rod 9 to slide up and protrude above the lifting platform 6. Subsequently, the item is placed on the lifting platform 6, and the limiting slide rod 9 covering the item is compressed and stored inside the lifting platform 6, squeezing the first spring 11. For the uncovered part, the position of the limiting slide rod 9 remains unchanged, quickly limiting the side of the placed item.

[0026] Please see Figure 4-5 The steering wheel vehicle body 1 has a guide groove inside, and a limiting slide plate 12 is slidably connected inside the guide groove. The limiting slide plate 12 is set on the lower surface of the lifting platform 6. A limiting slider 13 is set on the outer surface of the limiting slide plate 12. A second electric push rod 14 is set inside the steering wheel vehicle. A fixed plate 15 is set at the output end of the second electric push rod 14. A support slide rod is slidably connected inside the fixed plate 15. An adjusting plate 16 is set at one end of the support slide rod. An adjusting block 17 is set on the outer surface of the adjusting plate 16. The adjusting block 17 is adapted to the position of the limiting slider 13. A positioning piece is set at the end of the support slide rod away from the adjusting plate 16. A second spring 18 is set between the adjusting plate 16 and the fixed plate 15.

[0027] Specifically, during the lifting process of the lifting platform 6, the limiting slider 13 presses the adjusting block 17, which in turn causes the adjusting plate 16 and the support slide rod to slide relative to the fixed plate 15, compressing the second spring 18. When the lifting platform 6 stops lifting, under the elastic force of the second spring 18, the adjusting block 17 is locked onto the outer surface of the limiting slider 13, limiting the limiting slider 13 and improving the support stability of the lifting platform 6 after lifting (both the limiting slider 13 and the adjusting block 17 are right-angled triangles, as shown in the figure).

[0028] Please see Figure 2 The adjustment groove is equipped with a servo motor 19. One end of the output shaft of the servo motor 19 is equipped with a first bevel gear 20. The outer surface of the first bevel gear 20 is meshed with a second bevel gear 21. The second bevel gear 21 is located in the middle of the bidirectional screw 2.

[0029] Specifically, the servo motor 19 ensures the power source for the bidirectional screw 2 to rotate.

[0030] Please see Figure 3 The number of upper limit slide rods 9 in the connecting plate 8 is several, and they are evenly distributed inside the connecting plate 8.

[0031] Specifically, the multiple limit sliders 9 ensure that the limit components can cover all positions on the plane of the lifting platform 6.

[0032] Please see Figure 2 , Figure 4 The number of limiting slide plates 12 is several, and they are evenly distributed on the bottom surface of the lifting platform 6.

[0033] Specifically, the multiple sets of limit slides 12 effectively ensure the stability of the upgrade platform after it is raised or lowered.

[0034] Please see Figure 2 The bidirectional screw 2 has two adjusting rings 3 and two support plates 4, which are symmetrical to each other.

[0035] Specifically, the symmetrical arrangement of the two sets of adjusting rings 3 and support plates 4 allows the lifting platform 6 to be raised and lowered in a balanced manner.

[0036] Before use, the first electric push rod 7 is extended to allow the connecting plate 8 and the limiting slide rod 9 to slide upwards and protrude above the lifting platform 6. Next, the corresponding transport item is placed on the lifting platform 6. The limiting slide rod 9 covering the item is compressed and retracted into the lifting platform 6, squeezing the first spring 11. For the uncovered portion, the limiting slide rod 9 remains in position, quickly limiting the side of the placed item. Subsequently, the steering wheel is controlled by an external controller to move the item to the appropriate position. Then, the servo motor 19 is rotated, driving the first bevel gear 20 to rotate. Under the action of the second bevel gear 21, the bidirectional screw 2 rotates, thereby rotating the support plate 4. This causes the lifting platform 6 to slide upwards along the limiting slide plate 12, raising and lowering the steering wheel's working surface. During the ascent of the lifting platform 6, the limiting slider 13 squeezes the adjusting block 17, causing the adjusting plate 16 and the supporting slide rod to slide relative to the fixed plate 15, squeezing the second spring. 18. When the lifting platform 6 stops lifting, under the elastic force of the second spring 18, the adjusting block 17 is engaged with the outer surface of the limiting slider 13, limiting the limiting slider 13 and improving the support stability of the lifting platform 6 after lifting (both the limiting slider 13 and the adjusting block 17 are right-angled triangles, as shown in the figure). After rising to the corresponding position, the first electric push rod 7 is retracted, so that the connecting plate 8 and the limiting slide rod 9 are fully housed inside the lifting platform 6, allowing the items to be quickly transferred. After the items are transferred, the second electric push rod 14 is controlled to retract, so that the adjusting block 17 is disengaged from the limiting slider 13. Subsequently, the servo motor 19 is rotated in the opposite direction, so that the lifting platform 6 moves down to the initial position of the steering wheel car, completing the lifting operation. This gives the steering wheel car lifting mechanism the effect of increasing the stability of the lifting structure, improving the safety of the steering wheel car lifting structure, and optimizing the steering wheel car limiting components, facilitating the quick limiting of items.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
