Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, and more specifically, to an auxiliary support device for tire removal and installation in automotive repair. Background Technology

[0002] In the process of automobile maintenance, tire removal and installation is a frequent and crucial operation. With the continuous growth of automobile ownership and the increasing diversity of tire specifications, the demand for efficient, safe and universal tire removal and installation auxiliary equipment is becoming more and more urgent.

[0003] Currently, jacks are primarily used to support vehicles during tire installation and removal. While jacks can raise the car body to a certain height, creating conditions for tire removal and installation, they have several drawbacks in actual use. Firstly, jack operation is relatively complex, requiring operators to frequently manually operate the jack's lifting control components, consuming significant time and energy. This cumbersome process is particularly pronounced when frequent adjustments to the support height are needed, greatly reducing maintenance efficiency. Secondly, the jack's support point is relatively singular, making it difficult to provide stable and balanced support to the vehicle. During tire installation and removal, the vehicle is prone to swaying, increasing the difficulty of operation and potentially causing the tire to slip unexpectedly, posing a serious threat to the operator's safety and causing inconvenience in daily use. Therefore, improvements are needed. Utility Model Content

[0006] The base has sliding grooves on both the left and right sides, a long groove inside the base, and a support plate movably connected to the top of the base. The support plate has short grooves on both the left and right sides.

[0007] The drive mechanism is disposed inside the long slot;

[0008] The support mechanism is disposed inside the base;

[0009] The supporting mechanism includes a square rod, the bottom end of which is movably connected to the bottom end of the base. A first hinge block is fixedly installed on the outer surface of the square rod. A moving rod is hinged inside the first hinge block.

[0016] As a preferred embodiment of this utility model, a wire is fixedly connected inside the base, and a fixing plate is fixedly installed at one end of the wire. An alarm and an indicator light are fixedly connected inside the fixing plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This is an auxiliary support device for tire removal and installation in automotive repair. When the moving block moves forward, it will drive two square rods to move towards each other through the movable rod. At this time, the two square rods will drive four sets of moving rods through two sets of first hinge blocks. Then, the four sets of moving rods will drive four sets of round rods to move towards each other through four sets of second hinge blocks. Subsequently, the four sets of round rods will drive four sets of connecting shafts to rotate around the four connecting shafts through four sets of rotating rods and four sets of rotating rods.

[0025] 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.

[0026] like Figures 1 to 4 As shown, this utility model provides an auxiliary support device for tire removal and installation in automotive repair, comprising:

[0027] The base 1 has sliding grooves 2 on both the left and right sides, and a long groove 28 inside the base 1. The top of the base 1 is movably connected to a support plate 12, and a short groove 13 is opened on both the left and right sides of the support plate 12.

[0028] The drive mechanism is located inside the long slot 28;

[0029] The support mechanism is located inside the base 1;

[0030] The supporting mechanism includes a square rod 3, the bottom end of which is movably connected to the bottom end inside the base 1. A first hinge block 4 is fixedly installed on the outer surface of the square rod 3. A moving rod 5 is hinged inside the first hinge block 4. A second hinge block 6 is hinged to the other end of the moving rod 5. A round rod 7 is fixedly installed on the outer surface of the second hinge block 6. There are four sets of round rods 7. The outer surfaces of the four sets of round rods 7 are slidably connected to the inside of the slide groove 2. A rotating rod 8 and a rotating rod 9 are respectively movably sleeved at the other end of the four sets of round rods 7. A connecting shaft 10 is movably sleeved inside the rotating rod 8 and the rotating rod 9. A pressing rod 11 is movably sleeved inside the other end of the rotating rod 8 and the rotating rod 9. The outer surface of the pressing rod 11 is slidably connected to the inside of the short groove 13.

[0031] Because the base 1 has an inclined design on both the front and rear sides, it is easy for the vehicle to move to the top of the base 1. When the two square rods 3 move towards each other, they will drive the two sets of first hinge blocks 4 to move towards each other. At this time, the two sets of first hinge blocks 4 will drive the four sets of moving rods 5 to move. Then, the four sets of moving rods 5 will drive the four sets of round rods 7 to move towards each other along the inside of the slide groove 2 through the four sets of second hinge blocks 6. At this time, the four sets of round rods 7 will drive the four sets of rotating rods 8 and four sets of rotating rods 9 to rotate around the four connecting shafts 10. During this process, the four sets of rotating rods 8 and four sets of rotating rods 9 will squeeze and push the inside of the four short grooves 13 through the four sets of pressing rods 11, thereby causing the support plate 12 to move upward as a whole. When the support plate 12 contacts the vehicle chassis during the upward movement, it will squeeze and push the car, causing the car to move upward, thereby achieving the effect of stably lifting the vehicle as a whole.

[0032] The drive mechanism includes:

[0033] Motor 14, the back of motor 14 is fixedly connected to the inside of base 1, and the other end of the output shaft of motor 14 is fixedly sleeved with screw 15;

[0034] The moving block 16 is threadedly connected to the outer surface of the screw 15. The outer surface of the moving block 16 is slidably connected to the inside of the long groove 28. A movable rod 17 is hinged to the moving block 16. The other end of the movable rod 17 is hinged to the square rod 3.

[0035] When the motor 14 is running, the screw 15 will rotate. Since the outer surface of the screw 15 is threadedly connected to the inner thread of the moving block 16, and since the moving block 16 is slidably connected to the inside of the long groove 28, the screw 15 will drive the moving block 16 to move forward along the inside of the long groove 28 during rotation. At this time, the moving block 16 will drive the two movable rods 17 to move. The other ends of the two movable rods 17 will pull the two square rods 3, causing the two square rods 3 to move towards each other.

[0036] The base 1 has a connecting block 18 on its surface and a bolt 19 inside the connecting block 18. The base 1 and the connecting block 18 are fixedly connected by the bolt 19.

[0037] Due to the design of the connecting block 18, the bolt 19 can be easily connected to the base 1 as a whole through the connecting block 18. Furthermore, due to the design of the connecting block 18 and the bolt 19, the base 1 as a whole can be easily and firmly connected to the ground or other objects.

[0038] Among them, a circular block 20 is movably sleeved inside the top of the base 1, and a vertical rod 21 is interactively sleeved inside the circular block 20. The outer surface of the vertical rod 21 is fixedly connected to the inside of the top of the base 1, and a conductive block 22 is fixedly installed in the center of the bottom of the circular block 20.

[0039] Since the circular block 20 is movably connected to the top of the base 1, when the vehicle tire runs over the circular block 20, the circular block 20 will cause the conductive block 22 to move downward along the inside of the base 1. Due to the design of the vertical rod 21, the circular block 20 will be more stable when moving up and down.

[0040] Among them, a spring 23 is fixedly installed at the bottom end of the round block 20, and the bottom end of the spring 23 is fixedly connected to the inside of the top end of the base 1.

[0041] When the circular block 20 moves downward, it will compress the spring 23. Due to the design of the spring 23, the circular block 20 will have a good reset effect.

[0042] The base 1 has a wire 24 fixedly connected inside, and a fixing plate 25 is fixedly installed at one end of the wire 24. An alarm 26 and an indicator light 27 are fixedly connected inside the fixing plate 25.

[0043] Because there are four breaks in the conductor 24, when the conductive block 22 moves downward, it will come into contact with the breaks in the conductor 24, making the conductor 24 in series. Therefore, when the vehicle tires press on the four round blocks 20 at the same time, the four conductive blocks 22 will come into contact with the four breaks in the conductor 24. At this time, the current can supply power to the fixing plate 25 through the conductor 24. The fixing plate 25 will then supply power to the indicator light 27 and the alarm 26 at the same time, causing the indicator light 27 to light up and the alarm 26 to sound an alarm to remind the operator that the vehicle has reached the predetermined position, thereby achieving the effect of locating the vehicle.

[0044] Working principle and usage process of this utility model:

[0045] When the operator needs to install or remove a car tire, the operator first guides the driver to drive the vehicle to the top of the base 1. Because the base 1 has an inclined design on both sides, it facilitates the vehicle's movement to the top. During this process, the vehicle's four wheels will successively press and push the four circular blocks 20, causing the circular blocks 20 to move downwards along the inside of the top of the base 1. During this process, the circular blocks 20 will compress the spring 23. Due to the elastic force of the spring 23, the movement of the circular blocks 20 will have a good restoring effect. Simultaneously, the conductive block 22 will... As the vehicle moves downwards, the conductive block 22 will contact the break point of the wire 24 during its downward movement. When the four wheels of the vehicle contact the four circular blocks 20 respectively, all four conductive blocks 22 will contact the break point of the wire 24, making the wire 24 connected in series. This allows the current to be guided through the wire 24 to the fixing plate 25. At this time, the fixing plate 25 will transmit power to the alarm 26 and the indicator light 27. The indicator light 27 will light up, and the alarm 26 will emit a warning sound to remind the operator that the vehicle has moved to the predetermined position, thereby realizing the function of automatically locating the vehicle.

[0046] Next, the operator starts motor 14, at which point screw 15 will rotate. Since the outer surface of screw 15 is threadedly connected to the inner thread of moving block 16, the rotation of screw 15 will drive moving block 16. Because the outer surface of moving block 16 is slidably connected to the inside of long groove 28, the movement of moving block 16 will be limited by the inside of long groove 28, allowing moving block 16 to only move forward and backward. At this time, moving block 16 will move forward under the drive of screw 15. During this process, moving block 16 will simultaneously drive two movable rods 17 to move. The other ends of the two movable rods 17 will pull two square rods 3, causing the two square rods 3 to drive two sets of first hinge blocks 4 to move towards each other. Simultaneously, the two sets of first hinge blocks 4 will drive four sets of moving rods 5 respectively. During the movement, the other ends of the four sets of moving rods 5 will pull the four sets of second hinge blocks 6, causing the four sets of second hinge blocks 6 to drive the four sets of round rods 7 to move towards each other along the inside of the slide groove 2. At this time, the round rods 7 will drive the rotating rods 8 and 9 to rotate around the connection point with the connecting shaft 10. At the same time, the other ends of the rotating rods 8 and 9 will drive the pressing rods 11 to move. At this time, the outer surface of the pressing rods 11 will press and push the inside of the short groove 13 during the movement, thereby causing the support plate 12 to move upward. Then, the top of the support plate 12 will contact the car chassis during the upward movement. At this time, the top of the support plate 12 will press and push the car chassis, thereby causing the car to move upward, thus realizing the function of stabilizing the entire vehicle.
