Description

Technical Field

[0001] This utility model relates to the field of tire positioning technology, specifically to an automobile tire positioning device. Background Technology

[0002] Car tires are one of the most important components of a car. With the continuous increase in the number of cars on the road, the demand for tire repair and maintenance is also growing. When repairing or assembling car tires, it is necessary to align them.

[0003] Currently, in existing technologies, tire positioning is typically achieved by a drive module that moves a positioning clamp to position the tire. However, during tire positioning, the clamp may exert excessive clamping force on the tire. This excessive clamping can not only cause damage such as indentations and deformation on the tire surface, affecting the tire's appearance and structural integrity, but more importantly, it significantly increases the difficulty of subsequent tire rotation and adjustment. During maintenance, the tire needs to be rotated frequently for multi-angle inspections, balance adjustments, or specific maintenance operations. Excessive clamping force can hinder the smooth rotation of the tire and reduce maintenance efficiency. Therefore, a tire positioning device for automobiles is proposed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 This utility model proposes a car tire positioning device, including a fixed frame 1, a trapezoidal seat 2 fixedly connected to the fixed frame 1, a support positioning component 3 provided in the trapezoidal seat 2, and an auxiliary positioning component 5 provided on the fixed frame 1.

[0030] In an embodiment of this utility model, in order to automatically position the car tires, the support positioning assembly 3 specifically includes a mounting frame 31, a hinge rod 34, and a positioning shaft 36. A support roller 32 is rotatably connected to the mounting frame 31, and an elastic telescopic rod 33 is fixedly connected to the lower side of the mounting frame 31. One end of the hinge rod 34 is hinged to the mounting frame 31, and the other end of the hinge rod 34 is hinged to a swing rod 35. A rotating roller 37 is rotatably connected to the swing rod 35. The positioning shaft 36 passes through the swing rod 35 and is rotatably connected to the swing rod 35. An installation groove 21 is provided in the trapezoidal base 2. The bottom of the elastic telescopic rod 33 is fixedly installed in the installation groove 21. Both ends of the positioning shaft 36 are fixedly connected to the installation groove 21. Two sets of rotating rollers 37 are provided. Furthermore, the two sets of rotating rollers 37 are symmetrically arranged with the central axis of the support roller 32 as the axis of symmetry. The two sets of rotating rollers 37, together with the support roller 32, provide positioning support for the car tire. When the tire is placed on the support roller 32, it is subjected to gravity, and the mounting frame 31 presses down the telescopic end of the elastic telescopic rod 33. During the downward movement of the mounting frame 31, the hinge rod 34 is driven to move, and then the hinge rod 34 drives the swing rod 35 to move. The swing rod 35 rotates around the positioning axis 36, so that the rotating rollers 37 position the tire. This positioning method can effectively avoid applying excessive pressure to the tire, prevent damage such as indentations and deformation on the tire surface, reduce tire wear caused by improper positioning, and facilitate subsequent rotation and adjustment of the tire.

[0031] Furthermore, to improve the stability of the car tire during positioning, the auxiliary positioning component 5 specifically includes a guide seat 51. A bidirectional screw 52 is rotatably connected to the inner wall of the guide seat 51, and a motor 53 is fixedly connected to the outer wall of the guide seat 51. The output shaft of the motor 53 is fixedly connected to the bidirectional screw 52. A threaded block 54 is threadedly connected to the bidirectional screw 52. The threaded block 54 is slidably connected to the inner wall of the guide seat 51 for guiding and limiting the threaded block 54. A connecting rod 55 is fixedly connected to the threaded block 54. A pressure roller 56 is rotatably connected to the end of the connecting rod 55 away from the threaded block 54. Two sets of pressure rollers 56 are provided, and the two sets of pressure rollers 56 are symmetrically arranged about the center line of the guide seat 51. After the tire is positioned, the motor 53 is started, and the output shaft of the motor 53 rotates, driving the bidirectional screw 52 to rotate. As a result, the threaded block 54 slides in the guide seat 51, causing the two sets of pressure rollers 56 to abut against the car tire, thereby assisting in the positioning of the car tire and improving the stability of the tire during positioning.

[0032] Furthermore, a cylinder 4 is fixedly installed in the mounting slot 21. The cylinder 4 is located directly below the mounting frame 31. A push block 41 is fixedly connected to the output end of the cylinder 4. The output end of the cylinder 4 drives the push block 41 to rise, which in turn drives the mounting frame 31 to rise. The support roller 32 pushes out the car tire, making it convenient to remove the tire.

[0033] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0034] In use, the tire is first placed on the support roller 32. Under the action of gravity, the mounting frame 31 presses down the telescopic end of the elastic telescopic rod 33. During the downward movement of the mounting frame 31, the hinge rod 34 is driven to move, and then the hinge rod 34 drives the swing rod 35 to move. The swing rod 35 rotates around the positioning shaft 36, so that the rotating roller 37 positions the tire. Then the starter motor 53 is started. The output shaft of the motor 53 rotates, which drives the bidirectional screw 52 to rotate. Then the threaded block 54 slides in the guide seat 51, so that the two sets of pressure rollers 56 abut against the car tire and provide auxiliary positioning for the car tire. When the car tire needs to be removed, the output end of the cylinder 4 drives the ejector block 41 to rise, which can drive the mounting frame 31 to rise. The support roller 32 ejects the car tire, making it easy to remove the tire.
