Description

Technical Field

[0001] This utility model relates to the field of automobile repair technology, specifically to a tire removal device for automobile repair. Background Technology

[0002] Tires are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring good contact with the road surface, and guaranteeing vehicle performance. Tire removal devices are used during automotive repairs to remove tires, making it easier for mechanics to inspect the underside of the vehicle.

[0003] In the process of developing this application, the following problems were discovered with this technology: Currently, some simple tire removal devices exist in the market. However, these devices have significant limitations in actual use. They are typically only capable of removing tires of specific heights and sizes, lacking sufficient flexibility and making it difficult to adapt to the removal needs of tires with varying installation heights on different vehicle models. When faced with large vehicles or tires with special designs, these devices are even more inadequate and almost completely fail to function properly. This limitation significantly restricts their application scenarios.

[0004] Therefore, based on the above search and in conjunction with existing technology, this application proposes a tire removal device for automobile repair. Utility Model Content

[0005] The purpose of this invention is to provide a tire removal device for automobile repair, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tire removal device for automobile repair includes a base, a removal mechanism for quickly removing and moving a tire is slidably connected to the upper surface of the base, positioning mechanisms for positioning the removal mechanism are slidably connected to the left and right sides of the removal mechanism, and a protective mechanism for shielding and protecting the internal equipment of the removal mechanism is installed on the front of the removal mechanism.

[0008] Furthermore, the disassembly mechanism includes a U-shaped fixing plate, a slider is slidably connected inside the U-shaped fixing plate, a motor is installed at the top of the U-shaped fixing plate to drive the slider to slide inside the U-shaped fixing plate, five sets of disassembly sleeves for disassembling tire fastening bolts are installed at the front end of the slider, a second motor and two sets of side plates are installed on the front of the slider, and a disc is installed on the front of the two sets of side plates.

[0009] Furthermore, the positioning mechanism includes two sets of connecting plates, which are slidably connected to the left and right ends of the U-shaped fixing plate, respectively, and suction cups are slidably connected to the outer ends of the connecting plates.

[0010] Furthermore, a fixing ring is installed on the front side of the disk.

[0011] Furthermore, the protective mechanism includes an L-shaped fixing plate, which is installed on the front of the base, and a fixing circular frame is slidably connected inside the L-shaped fixing plate.

[0012] Furthermore, two sets of magnetic rods are installed inside the fixed circular frame.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a starter motor to drive a slider to move up and down inside a U-shaped fixing plate, adjusting the positions of five sets of disassembly sleeves to one side of the five sets of fastening bolts for tire removal. Then, by pushing the U-shaped fixing plate, the five sets of disassembly sleeves are inserted into the outer ends of the five sets of fastening bolts. A second starter motor drives a gear to rotate the five sets of disassembly sleeves and fastening bolts, pulling the U-shaped fixing plate and moving the five sets of fastening bolts backward. This allows the five sets of disassembly sleeves to disassemble the five sets of fastening bolts inside the tire during rotation, thus completing the rapid tire removal. By adjusting the height of the five sets of disassembly sleeves using the first starter motor, the subsequent disassembly mechanism can disassemble tires at various heights during startup, thereby expanding the disassembly range and improving the practicality of the device.

[0015] 2. This utility model moves two sets of suction cups up and down by pushing two sets of connecting plates, adjusting the front of the two sets of suction cups to one side of the vehicle body to be disassembled. Then, by pushing two sets of push rods, the two sets of suction cups are moved forward, so that the front of the two sets of suction cups are respectively attached to the outer surface of the vehicle. This allows the subsequent positioning mechanism to restrict the left and right movement of the disassembly mechanism and the base, thereby minimizing the risk of the base tipping over during use and thus improving the stability of the device during use.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Attached Figure 4 Further explanation of this utility model:

[0023] A tire removal device for automobile repair includes a base 1. A tire removal mechanism 2 for quick tire removal is slidably connected to the upper surface of the base 1. Positioning mechanisms 3 for positioning the tire removal mechanism 2 are slidably connected to both the left and right sides of the tire removal mechanism 2. A protective mechanism 5 for shielding and protecting the internal equipment of the tire removal mechanism 2 is installed on the front of the tire removal mechanism 2. Specifically, by activating the tire removal mechanism 2, the removal height of the moving tire removal mechanism 2 can be adjusted, allowing the tire removal mechanism 2 to adapt to the height of the rear tire lifted by the hydraulic jack during use. This enables the tire removal mechanism 2 to remove tires at various heights during activation, thereby expanding the removal range of the tire removal mechanism 2 and improving the practicality of the device. By pushing the protective mechanism 5 to abut against the front end of the tire removal mechanism 2, the protective mechanism 5 shields and protects the internal equipment of the tire removal mechanism 2, thereby minimizing the risk of foreign objects getting stuck inside the tire removal mechanism 2 and causing damage to the tire removal mechanism 2 during activation.

[0024] Specifically, the disassembly mechanism 2 includes a U-shaped fixing plate 201, with a slider 204 slidably connected inside the U-shaped fixing plate 201. A motor 202 is installed at the top of the U-shaped fixing plate 201 to drive the slider 204 to slide inside the U-shaped fixing plate 201. Five sets of disassembly sleeves 210 for disassembling tire fastening bolts are installed at the front end of the slider 204. A slot is provided on the upper surface of the base 1, and the U-shaped fixing plate 201 is slidably connected inside the slot of the base 1. Through holes are provided at the bottom and top of the inner wall of the U-shaped fixing plate 201. A screw 203 is rotatably connected inside the two sets of through holes of the U-shaped fixing plate 201. The slider 204 is threadedly connected to the outer end of the screw 203. The output shaft of the motor 202 is installed on the screw. At the top of 203, a motor 205 and two sets of side plates 206 are mounted on the front of the slider 204. The two sets of side plates 206 are respectively mounted on the left and right sides of the motor 205. A disc 207 is mounted on the front of the two sets of side plates 206. A through hole is opened on the front of the disc 207. The output shaft of the motor 205 passes through the through hole inside the disc 207 and a rotating rod 208 is installed. Five sets of grooves are opened on the front of the disc 207. Five sets of disassembly sleeves 210 are rotatably connected inside the five sets of grooves of the disc 207. A gear 209 is mounted on the outer surface of the rotating rod 208. The external teeth of the gear 209 are meshed with five sets of gears 211. The five sets of gears 211 are respectively mounted on the outer surface of the five sets of disassembly sleeves 210.

[0025] In this embodiment, the starting motor 202 drives the slider 204 to move up and down inside the U-shaped fixing plate 201, adjusting the position of the five sets of disassembly sleeves 210 to one side of the five sets of fastening bolts for tire removal. Then, by pushing the U-shaped fixing plate 201, the five sets of disassembly sleeves 210 are inserted into the outer ends of the five sets of fastening bolts. The starting motor 205 drives the gear 209 to drive the five sets of gears 211 to rotate the five sets of disassembly sleeves 210 and fastening bolts, pulling the U-shaped fixing plate 201 to move the five sets of fastening bolts backward. This allows the five sets of disassembly sleeves 210 to disassemble the five sets of fastening bolts inside the tire during rotation, thus completing the rapid disassembly of the tire. By adjusting the height of the five sets of disassembly sleeves 210 by the starting motor 202, the subsequent disassembly mechanism 2 can disassemble tires at various heights during startup, thereby expanding the disassembly range of the subsequent disassembly mechanism 2 and improving the practicality of the device.

[0026] Specifically, the positioning mechanism 3 includes two sets of connecting plates 301, which are slidably connected to the left and right ends of the U-shaped fixing plate 201. A suction cup 302 is slidably connected to the outer end of the connecting plate 301. A groove is provided inside the connecting plate 301, and a push rod 303 is slidably connected inside the groove of the connecting plate 301. The suction cup 302 is installed on the front of the push rod 303. Slots are provided on both the left and right sides of the U-shaped fixing plate 201, and the two sets of connecting plates 301 are slidably connected inside the two sets of slots of the U-shaped fixing plate 201.

[0027] In this implementation scheme, by pushing the two sets of connecting plates 301, the two sets of suction cups 302 are moved up and down, adjusting and moving the front of the two sets of suction cups 302 to one side of the vehicle body to be disassembled. Then, by pushing the two sets of push rods 303, the two sets of suction cups 302 are moved forward, so that the front of the two sets of suction cups 302 are respectively attached to the outer surface of the vehicle. This allows the subsequent positioning mechanism 3 to restrict the left and right movement of the disassembly mechanism 2 and the base 1, thereby minimizing the risk of the base 1 tipping over during use and thus improving the stability of the device during use. The two sets of push rods 303 are slidably connected to the grooves of the two sets of connecting plates 301, so that when the U-shaped fixing plate 201 slides in the slot of the base 1, it simultaneously drives the two sets of connecting plates 301 to slide at the outer ends of the two sets of push rods 303. This minimizes the risk of the positioning mechanism 3 obstructing the normal adjustment and movement of the U-shaped fixing plate 201 by the staff during use.

[0028] Specifically, a fixing ring 4 is mounted on the front of the disc 207, and the fixing ring 4 is located at the outer end of the fifth set of gears 211.

[0029] In this embodiment, the fixing ring 4 is positioned at the outer end of the fifth set of gears 211, so that the fixing ring 4 blocks the fifth set of gears 211, thereby minimizing the risk of collision between the fixing ring 4 and the fifth set of gears 211 during operation of the device, which could result in injury to the operator. This improves the safety of the subsequent disassembly mechanism 2 during use.

[0030] Specifically, the protective mechanism 5 includes an L-shaped fixing plate 501, which is installed on the front of the base 1. A fixing frame 503 is slidably connected inside the L-shaped fixing plate 501. A protective cover plate 502 is installed on the inner wall of the fixing frame 503. The position of the fixing ring 4 is located on the moving path of the protective cover plate 502.

[0031] In this embodiment, the starting motor 202 drives the fixed ring 4 to move upward, adjusting the position of the fixed ring 4 to the moving path of the protective cover 502. Then, by pushing the fixed frame 503, the back of the fixed frame 503 abuts against the front of the fixed ring 4, so that the fixed ring 4 and the protective mechanism 5 form a sealed space to shield the five sets of gears 211 and gear 209. This minimizes the risk of dust or debris entering the connection between the five sets of gears 211 and gear 209 during the device's idle period, thus preventing wear on the gears 209 and 211 during rotation and improving the service life of the subsequent disassembly mechanism 2.

[0032] Specifically, two sets of magnetic rods 6 are installed inside the fixed circular frame 503, and the fixed circular ring 4 is made of metal iron.

[0033] In this embodiment, when the back of the subsequent fixed circular frame 503 abuts against the front of the fixed ring 4, the back of the two sets of magnetic rods 6 are attracted to the front of the fixed ring 4, so that the two sets of magnetic rods 6 restrict the movement of the fixed circular frame 503 at the front end of the fixed ring 4, thereby minimizing the movement of the subsequent protective mechanism 5 during use, thus improving the stability of the subsequent protective mechanism 5 during use.

[0034] In summary: By starting motor 202, the slider 204 moves up and down inside the U-shaped fixing plate 201, adjusting the positions of the five sets of disassembly sleeves 210 to one side of the five sets of tire fastening bolts. Then, by pushing the U-shaped fixing plate 201, the five sets of disassembly sleeves 210 are inserted into the outer ends of the five sets of fastening bolts. By starting motor 205, gear 209 drives gear 211 to rotate the five sets of disassembly sleeves 210 and fastening bolts, pulling the U-shaped fixing plate 201 and moving the five sets of fastening bolts. The mechanism moves backward, causing the five sets of disassembly sleeves 210 to disassemble the five sets of fastening bolts inside the tire during rotation. By pushing the two sets of connecting plates 301, the two sets of suction cups 302 are moved up and down, adjusting the front of the two sets of suction cups 302 to one side of the vehicle body being disassembled. Then, by pushing the two sets of push rods 303, the two sets of suction cups 302 are moved forward, causing the front of the two sets of suction cups 302 to adhere to the outer surface of the vehicle. This allows the subsequent positioning mechanism 3 to restrict the left and right movement of the disassembly mechanism 2 and the base 1. At the same time, by starting the motor 202, the fixing ring 4 is moved upward, adjusting its position to the movement path of the protective cover 502. Then, by pushing the fixing frame 503, the back of the fixing frame 503 is brought into contact with the front of the fixing ring 4, so that the fixing ring 4 and the protective mechanism 5 form a sealed space to shield the five sets of gears 211 and 209.
