[0002] In automotive repair, tires are the most frequently repaired component. Tires are usually connected to the rims and are quite heavy, making tire repair inconvenient. Therefore, the rims need to be placed on rim locators for repair. However, existing rim locators cannot quickly locate the rims, posing a risk of the rims falling off and injuring repair personnel. Therefore, a locator tool that can solve the above problems is needed. Utility Model Content

[0003] To address the problem that existing wheel hub positioning frames cannot quickly position wheel hubs, posing a risk of wheel hubs falling off the positioning frame and injuring repair personnel, a quick positioning tool holder for automotive repair has been invented.

[0004] The technical solution of this utility model is a quick positioning tool holder for automotive repair, including a support frame. The support frame is characterized by a support plate rotatably connected to it, the support plate being connected to the support frame via an electric telescopic rod, a positioning plate rotatably connected to the support plate, a positioning component connected to the positioning plate, and a pressure sensor connected to the positioning component. The pressure sensor detects the pressure after the positioning component contacts the wheel hub, thereby controlling the positioning component to perform non-destructive positioning of the wheel hub. A limit plate is connected to the support frame, and a trigger component is provided on the limit plate and the support plate. The trigger component detects whether the support plate has rotated to a position perpendicular to the support frame, thereby controlling whether the electric telescopic rod is energized. The electric telescopic rod, positioning component, pressure sensor, and trigger component are electrically connected to a control module assembly.

[0005] Preferably, the lower end face of the support plate is connected to two connecting shafts, which are rotatably connected to the support frame.

[0006] Preferably, the support plate has a rotating groove, and a plurality of connecting rods are provided in the rotating groove. The other end of the connecting rod is fixedly connected to the positioning plate. The support plate has a limiting groove that communicates with the rotating groove. A limiting screw that is threadedly connected to the connecting rod is provided in the limiting groove. The side end face of the support plate has a positioning hole that communicates with the limiting groove, so that the limiting screw is threadedly connected to the connecting rod through the positioning hole.

[0007] Preferably, the support plate is connected to an upper connector, the support frame is connected to a reinforcing rod, the reinforcing rod is connected to a lower connector, and the two ends of the electric telescopic rod are respectively connected to an upper hinge joint and a lower hinge joint, which are rotatably connected to the upper connector and the lower connector respectively.

[0008] Preferably, the positioning assembly includes several positioning rods, an adjusting plate, a first adjusting gear, a second adjusting gear, a rotating shaft, and a drive motor. The drive motor is connected to the positioning plate and electrically connected to the control module assembly. The rotating shaft is connected to the output shaft of the drive motor. The first adjusting gear and the second adjusting gear are connected together with the rotating shaft. The positioning plate has several adjusting holes.

[0019] This application discloses a multifunctional storage box. (Refer to...) Figure 1 The tool rack includes a support frame 1, which supports the entire tool rack, allowing it to stand stably on the ground. A support plate 6 is rotatably connected to the support frame 1. Specifically, connecting shafts 7 are welded and fixed to both ends of the lower surface of the support plate 6, connecting the connecting shafts 7 and the support plate 6 together to form a single unit. The connecting shafts 7 are rotatably connected to the support frame 1 via bearings, allowing the support plate 6 to rotate relative to the support frame 1. A support rod 10 is welded to or detachably fixed to the support frame 1 via bolts, supporting the end of the support plate 6 away from the connecting shafts 7, ensuring the support plate 6 can be stably placed horizontally on the support frame 1.

[0020] Reference Figure 1 , Figure 4A limiting plate 29 is detachably and fixedly connected to the support frame 1 by bolts, so that the limiting plate 29 and the support frame 1 are connected together to form a whole. A trigger assembly is provided on the limiting plate 29 and the support plate 6, so that the trigger assembly can detect whether the support plate 6 has rotated to a position perpendicular to the support frame 1. The trigger assembly includes a first trigger head 32, a second trigger head 35, a first spring 31, and a second spring 34. A first telescopic hole 30 is provided on the limiting plate 29, and the first trigger head 32 is connected to the first telescopic hole 30 through the first spring 31, so that the first trigger head 32 can move within the first telescopic hole 30. A second telescopic hole 33 is provided on the support plate 6, and the second trigger head 35 is connected to the second telescopic hole 33 through the second spring 34, so that the second trigger head 35 can move within the second telescopic hole 33. The first trigger head 32 extends partially beyond the first telescopic hole 30, allowing it to extend partially beyond the first telescopic hole 30 without external force. The second trigger head 35 extends partially beyond the second telescopic hole 33, allowing it to extend partially beyond the second telescopic hole 33 without external force. The triggering components are electrically connected to the control module assembly. Specifically, the first trigger head 32 and the second trigger head 35 are made of common single-point metal materials and are electrically connected to the control module assembly. The control module assembly is a common microcontroller control circuit board module assembly. When the support plate 6 rotates to be perpendicular to the support frame 1, the first trigger head 32 and the second trigger head 35 come into contact, thereby activating the circuit containing the first trigger head 32 and the second trigger head 35, and generating a trigger signal.

[0021] Reference Figure 1The support plate 6 is connected to the support frame 1 via an electric telescopic rod 5, allowing the support plate 6 to rotate relative to the support frame 1 by extending or retracting the electric telescopic rod 5. Specifically, an upper connector 8 is welded to or detachably fixed to the support plate 6 via bolts, connecting the upper connector 8 to the support plate 6 to form a whole. A reinforcing rod 2 is welded to or detachably fixed to the support frame 1 via bolts, increasing the stability of the support frame 1. A lower connector 3 is welded to or detachably fixed to the reinforcing rod 2 via bolts, connecting the lower connector 3 to the reinforcing rod 2 to form a whole. An upper hinge joint 9 and a lower hinge joint 4 are welded to or detachably fixed to both ends of the electric telescopic rod 5, respectively, connecting the upper hinge joint 9 and the lower hinge joint 4 to both ends of the electric telescopic rod 5 to form a whole. The upper hinge joint 9 and the lower hinge joint 4 are rotatably connected to the upper connector 8 and the lower connector 3 respectively via hinge shafts. This allows one end of the electric telescopic rod 5 to be rotatably connected to the support plate 6 via the upper hinge joint 9 and the upper connector 8, and the other end of the electric telescopic rod 5 to be connected to the reinforcing rod 2 via the lower hinge joint 4 and the lower connector 3. Thus, the support plate 6 and the reinforcing rod 2 are connected together via the electric telescopic rod 5, and the extension and retraction of the electric telescopic rod 5 allows the support plate 6 to rotate about the connecting shaft 7. The electric telescopic rod 5 is electrically connected to the control module assembly, allowing the control module assembly to control the extension and retraction of the electric telescopic rod 5.

[0022] Reference Figure 1 , Figure 2A positioning plate 17 is rotatably connected to the support plate 6, allowing the positioning plate 17 to rotate relative to the support plate 6. Specifically, several connecting rods 12 are detachably fixed to the positioning plate 17 by bolts, and the connecting rods 12 are arranged in a ring on the positioning plate 17, forming a whole with the positioning plate 17. An annular rotation groove 11 is formed on the support plate 6, and the ends of the connecting rods 12 away from the positioning plate 17 are placed in the rotation groove 11. The support plate 6 has an annular limiting groove 13 that connects to the rotating groove 11. A limiting screw 14, threadedly connected to the connecting rod 12, is provided within the limiting groove 13. This limiting screw 14, positioned within the limiting groove 13, restricts the connecting rod 12, preventing it from detaching from the rotating groove 11. This allows the connecting rod 12 to rotate relative to the support plate 6 without affecting the rotation of both the connecting rod 12 and the limiting screw 14 within the rotating groove 11 and the limiting groove 13, respectively. This, in turn, allows the positioning plate 17 to rotate relative to the support plate 6. The side end face of the support plate 6 has a positioning hole 15 that connects to the limiting groove 13. The limiting screw 14 is threadedly connected to the connecting rod 12 through the positioning hole 15, facilitating its placement within the limiting groove 13. A cap 16 is engaged at the opening of the positioning hole 15, thereby sealing the positioning hole 15 and preventing external debris from entering the limiting groove 13 through the positioning hole 15 and affecting the threaded connection between the limiting screw 14 and the connecting rod 12.

[0023] Reference Figure 1 , Figure 3 , Figure 5A positioning assembly is connected to the positioning plate 17, enabling the wheel hub to be quickly positioned and connected to the positioning plate 17. A pressure sensor is connected to the positioning assembly, allowing the sensor to detect the pressure after the positioning assembly contacts the wheel hub, thereby controlling the positioning assembly to perform non-destructive positioning of the wheel hub. The positioning assembly includes several positioning rods 19, an adjusting plate 21, a first adjusting gear 25, a second adjusting gear 26, a rotating shaft 24, and a drive motor 23. The drive motor 23 is detachably fixed to the end face of the positioning plate 17 near the support plate 6 via bolts. The drive motor 23 is a common bidirectional drive motor, allowing it to be connected to the positioning plate 17 as a whole. The drive motor 23 is electrically connected to the control module assembly, allowing the control module assembly to control the drive motor 23 to operate and rotate in both directions. The rotating shaft 24 is detachably connected to the output shaft of the drive motor 23 via a coupling, so that when the drive motor 23 is powered on, its output shaft drives the rotating shaft 24 to rotate. The first adjusting gear 25 and the second adjusting gear 26 are detachably and fixedly connected to the rotating shaft 24 by bolts, so that the rotation of the rotating shaft 24 drives the first adjusting gear 25 and the second adjusting gear 26 to rotate simultaneously. The positioning plate 17 has several adjusting holes 18, one end of the positioning rod 19 passing through the adjusting hole 18, so that the adjusting hole 18 limits the direction and distance of movement of the positioning rod 19. One end of the positioning rod 19 passes through the adjusting hole 18 and is detachably and fixedly connected to the adjusting plate 21 by bolts, so that the positioning rod 19 and the adjusting plate 21 are connected together to achieve simultaneous movement. Adjusting plates 21 are provided with adjusting grooves 22. The adjusting grooves 22 on the diagonally arranged adjusting plates 21 mesh with the first adjusting gear 25 and the second adjusting gear 26 respectively. This allows the rotating shaft 24 to rotate, driving the first adjusting gear 25 and the second adjusting gear 26. By utilizing the meshing adjusting grooves 22, several adjusting plates 21 can be moved simultaneously, thereby causing the positioning rod 19 to move simultaneously within the adjusting hole 18 towards or away from the end face axis of the positioning plate 17. This enables rapid positioning or release of the wheel hub. A limit cover 27 is detachably fixed to the positioning plate 17 by bolts. The limit cover 27 isolates and protects the drive motor 23, the first adjusting gear 25, and the second adjusting gear 26, preventing external dust, oil, etc., from contacting and damaging the drive motor 23, the first adjusting gear 25, and the second adjusting gear 26, thus affecting the movement of the positioning rod 19 by the drive motor 23. The limiting cover 27 has a connecting hole 28. The adjusting plate 21 passes through the limiting cover 27 through the connecting hole 28, which allows the adjusting plate 21 to move relative to the limiting cover 27. The connecting hole 28 also limits the movement of the adjusting plate 21, so that the adjusting tooth grooves 22 on the diagonally arranged adjusting plates 21 can always mesh with the first adjusting gear 25 and the second adjusting gear 26, thereby enabling the first adjusting gear 25 and the second adjusting gear 26 to rotate and drive several adjusting plates 21 to move simultaneously.A protective pad 20 is fitted onto the end of the positioning rod 19 furthest from the adjusting plate 21. This reduces the rigid pressure when the positioning rod 19 contacts the wheel hub, preventing damage to the wheel hub. A pressure sensor is positioned between the protective pad 20 and the positioning rod 19, and is electrically connected to the control module assembly. This allows the sensor to detect the pressure when the positioning rod 19 contacts the wheel hub, thus preventing excessive pressure between the positioning rod 19 and the wheel hub from causing damage.

[0024] In use, firstly, the electric telescopic rod 5 is retracted via the control module assembly as needed for maintenance, so that the support plate 6 and positioning plate 17 are positioned horizontally or vertically. Then, the wheel hub is placed on the positioning rod 19 at the positioning plate 17, so that the protective pad 20 on the positioning rod 19 contacts the wheel hub. Next, the drive motor 23 is operated to expand the positioning rod 19 outward until the pressure value of the pressure sensor on the positioning rod 19 reaches the set pressure. Then, the drive motor 23 is de-energized via the control module assembly, and the positioning rod 19 stops expanding outward, thus completing the rapid positioning of the wheel hub. During maintenance, the extension and retraction of the electric telescopic rod 5 can be controlled as needed to control the position of the wheel hub on the support frame 1.

[0025] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
