Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1 to 3, an embodiment provided by the present utility model: a tire assembly auxiliary device, including a bottom plate 1. On the left side of the top of the bottom plate 1, a lifting assembly for height adjustment is fixedly connected. The lifting assembly is used to adjust the height of the structure to meet the application in different situations. On the right side of the top of the bottom plate 1, a protective shell 2 is fixedly connected. Inside the protective shell 2, a rotating assembly for rotation is arranged. The top of the protective shell 2 is rotatably connected with a rotating block 11. The rotating assembly is used to rotate the rotating block 11. The top of the rotating block 11 is fixedly connected with a housing 3. The housing 3 plays a role in protecting and fixing the structure. On the inner bottom wall of the housing 3, a bottom ring 13 is fixedly connected. Inside the bottom ring 13, a plurality of sliding bars 12 are slidably connected. A plurality of sliding grooves are arranged inside the bottom ring 13. The sliding bars 12 slide in the sliding grooves of the bottom ring 13. At the top of the far ends of the plurality of sliding bars 12 away from each other, a rotating block 10 is fixedly connected. At the top of the plurality of rotating blocks 10, a fixing rod 4 is fixedly connected. The fixing rod 4 moves as the rotating block 10 rotates. On the inner top wall of the housing 3, a motor 6 is fixedly connected. The driving end of the motor 6 is fixedly connected with a driving gear 7. The motor 6 is responsible for providing power to the driving gear 7. The outside of the driving gear 7 is meshed with a toothed ring 8. When the driving gear 7 rotates, the toothed ring 8 rotates. After the position of the fixing rod 4 is adjusted, the wheel hub can be placed and fixed at the same time.

[0033] Refer to Figure 2 , Figure 4 , Figure 5 , the lifting assembly includes a base 21. On the top of the base 21, an electric slide rail 22 is fixedly connected. The outside of the electric slide rail 22 is slidably connected with a slider 23. The slider 23 can move up and down through the electric slide rail 22. On the right side of the slider 23, an ear seat 26 is fixedly connected. On the right side of the ear seat 26, an adjusting rod 24 is rotatably connected. The adjusting rod 24 can rotate in the ear seat 26. A groove 27 is opened inside the adjusting rod 24. The bottom end of the adjusting rod 24 is fixedly connected with a pressing block 25. The length of the adjusting rod 24 can be adjusted through the groove 27, and then the position of the pressing block 25 can be changed to adapt to different wheels.

[0034] Refer to Figures 2 to 4, the rotating assembly includes a rotating column 15. An external bevel gear one 16 is fixedly connected to the rotating column 15. The rotation of the bevel gear one 16 drives the rotation of the rotating column 15. A motor two 20 is fixedly connected to the top of the bottom plate 1. A driving rod 18 is fixedly connected to the driving end of the motor two 20. A bevel gear two 17 is fixedly connected to the right end of the driving rod 18. When the motor two 20 is started, it drives the driving rod 18 to rotate, thereby driving the bevel gear two 17 to rotate. The bottom side of the motor two 20 is fixedly connected to the top of the bottom plate 1. The external of the driving rod 18 is rotatably connected to a fixed seat 19. The fixed seat 19 functions to fix the driving rod 18. The bottom of the fixed seat 19 is fixedly connected to the top of the bottom plate 1. A plurality of rotating grooves 9 are evenly formed inside the toothed ring 8. The external of a rotating block 10 is slidably connected to the inside of each of the plurality of rotating grooves 9. The rotating block 10 moves in the rotating groove 9 when the motor one 6 is started. A plurality of moving grooves 14 are formed in the top of the housing 3. The external of a fixed rod 4 is slidably connected to the inside of the moving groove 14. The existence of the moving groove 14 allows the fixed rod 4 to move therein. A positioning rod 5 is fixedly connected to the bottom of the housing 3. The external of the positioning rod 5 is fixedly connected to the inside of the housing 3. The positioning rod 5 is used to position the center point of the wheel hub, making it easier to fix in the tire assembly auxiliary device.

[0035] Working principle: When assembling the tire, adjust the position of the fixed rod 4 according to the position of the screw holes in the wheel hub. Start the motor one 6. The motor one 6 drives the driving gear 7 to rotate. The rotation of the driving gear 7 drives the toothed ring 8 to rotate. There is a rotating block 10 in the rotating groove 9 of the toothed ring 8. When the toothed ring 8 rotates, the rotating groove 9 applies a thrust to the rotating block 10, causing the rotating block 10 to move along the rotating groove 9. The distances from the two ends of the rotating groove 9 to the center point of the toothed ring 8 are different. Therefore, when the rotating block 10 moves, the slide bar 12 slides inwards or outwards in the sliding groove of the bottom ring 13. One end of the inner side of the bottom ring 13 is connected to the fixed rod 4. When the slide bar 12 slides, the fixed rod 4 is adjusted to a suitable position. The wheel hub is fixed by the positioning rod 5, and a part of the tire is sleeved onto the wheel hub.

[0036] Adjust the position of the slider 23 through the electric slide rail 22 so that the ear seat 26 reaches a suitable height. Adjust the adjusting rod 24 to a suitable length through the groove 27 to press the extrusion block 25 against the tire. Drive the driving rod 18 to rotate through the motor two 20, so that the bevel gear two 17 drives the rotation of the bevel gear one 16, thereby driving the rotation of the rotating column 15. Then, the tire is rotated through the rotating block 11. At this time, under the pressure of the extrusion block 25 and its own rotation, the tire is assembled onto the wheel hub, realizing the assembly of the tire.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
