Description

Technical Field

[0001] The present application relates to the technical field of vehicle tire maintenance, and specifically discloses a vehicle tire maintenance device. Background Art

[0002] As one of the important parts of a car, car tires are always in contact with the road surface when the car is moving or stationary. During the driving process, they work together with the car suspension to mitigate the impact of the car, ensuring that the car has good ride comfort and smooth driving.

[0003] To ensure the long-term performance of automobile tires, they require regular maintenance. Typically, maintenance involves lifting the vehicle, removing the tire, and then placing the tire on a rotatable cylindrical support or flat surface for maintenance. However, performing maintenance on a cylindrical support requires lifting the tire and placing it on the support, which can be difficult for large tires to handle.

[0004] Therefore, in view of this, the inventor provides a vehicle tire maintenance device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that traditional large tires need to be transported and lifted and placed on a cylindrical support during maintenance, and are difficult to transport due to their heavy weight.

[0006] In order to achieve the above-mentioned purpose, the basic solution of the present invention provides a car tire maintenance device, including a connecting rod, side connecting rods respectively fixed to the two ends of the connecting rod, top connecting rods respectively fixed to the two sides of the top surface of the connecting rod, and handles arranged between the top ends of the top connecting rods on both sides. The inner side of the side connecting rods is provided with a support structure for supporting the tire, and the bottom of the connecting rod and the bottom of the side connecting rod are respectively provided with a moving mechanism.

[0007] Furthermore, the support structure includes a connecting block fixedly connected to the inner side of the free end of the side connecting rod and a first support rod arranged on the inner side of the connecting block and used to support the tire.

[0008] Furthermore, the first support rod is rotatably connected to the connecting block.

[0009] Furthermore, connecting plates are fixedly connected to both sides of the first support rod, a second support rod for supporting the tire is provided between the connecting plates on both sides, and a synchronous control structure for synchronously controlling the rotation of the first support rods on both sides is provided on the connecting rod.

[0010] Furthermore, the second support rod is rotatably connected between the connecting plates on both sides.

[0011] Furthermore, the synchronous control structure includes an electric push rod fixed to the connecting rod, a driven rod fixed to the output end of the electric push rod, and a driven mechanism respectively provided on both sides of the driven rod and used to drive the first support rod on the same side to rotate in the opposite direction.

[0012] Furthermore, the driven mechanism includes a first driven link hinged to one side of the bottom of the driven rod and a second driven link hinged to the free end of the first driven link, and the free end of the second driven link is fixed to the first support rod.

[0013] The principle and effect of this solution are:

[0014] Compared with the prior art, the present invention controls the lifting and lowering of the driven rod through an electric push rod, and transmits the power through the first driven connecting rod and the second driven connecting rod. When the driven rod rises, it drives the first support rod to rotate outward, so that the second support rod is lifted, and then the tire parked on the ground is lifted; when the driven rod descends, the second support rod descends, and the lifted tire is put down. The tire can be directly supported by the second support rods on both sides, and maintenance operations can be performed between the second support rods. This solves the problem that traditional large tires need to be carried and lifted and placed on a cylindrical bracket during maintenance, which is difficult to carry due to their heavy weight.

[0017] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0018] The reference numerals in the drawings of the specification include: right connecting rod 1, left connecting rod 2, connecting pipe 3, electric push rod 4, side connecting rod 5, first support rod 6, second support rod 7, second driven connecting rod 8, first driven connecting rod 9, driven rod 10, handle 11, tire 12.

[0019] Automobile tire maintenance device, implementing e.g. Figure 1 As shown:

[0020] The vehicle comprises a connecting rod, side links 5 fixedly mounted at each end of the connecting rod, top links fixedly mounted on either side of the top surface of the connecting rod, and a handle 11 mounted between the top ends of the top links. The handle 11 is slidable between the top ends of the top links. A movable mechanism is mounted at the bottom of each of the connecting rod and the side links 5. The mechanism comprises support blocks mounted at the bottoms of the connecting rod and the side links, and rotatable wheels mounted on the support blocks.

[0021] A support structure for supporting the tire 12 is installed on the inner side of the side connecting rod 5, including a connecting block fixedly installed on the inner side of the free end of the side connecting rod 5 and a first supporting rod 6 installed on the inner side of the connecting block and rotatable.

[0022] A connecting plate is fixedly mounted on each side of the first support rod 6, and a second support rod 7 is mounted between the connecting plates to support the tire 12. A synchronous control structure is also mounted on the connecting rod to synchronously control the rotation of the first support rods 6 on both sides, including an electric push rod 4 fixedly mounted on the connecting rod, a driven rod 10 fixedly mounted on the output end of the electric push rod 4, and a driven mechanism mounted on both sides of the driven rod 10 to drive the first support rod 6 on the same side to rotate in the opposite direction.

[0023] Blocks are installed on both sides of the bottom of the driven rod 10. The driven mechanism includes a first driven link 9 with one end hinged on the block and a second driven link 8 hinged to the other end of the first driven link 9. The free end of the second driven link 8 is fixedly connected to the free end of the first support rod 6.

[0024] In this embodiment, when the first support rod 6 rotates, the connecting plate and the second support rod 7 can be made to fit the ground.

[0025] In this embodiment, both the connecting rod and the driven rod 10 are retractable rods. Specifically, the connecting rod is divided into a left connecting rod 2 and a right connecting rod 1, and the driven rod 10 is divided into a left driven rod 10 and a right driven rod 10. The left ends of the right connecting rod 1 and the right driven rod 10 are fixedly mounted with a connecting tube 3. The right ends of the left connecting rod 2 and the left driven rod 10 are both inserted into the connecting tube 3. The connecting tube 3 has an internal threaded hole. By screwing in a bolt, the bottom of the bolt abuts against the top end surface of the inserted left connecting rod 2 and the left driven rod 10, thereby fixing the overall length of the connecting rod and the driven rod 10.

Figure 1 Place the tire 12 on the ground, and adjust the length of the connecting rod and the driven rod 10 so that the second support rod 7 can be located under the tire 12 and can support the tire 12;

[0027] Then, the output end of the electric push rod 4 is controlled to descend, and the first support rod 6 is driven to rotate inward through the first driven link 9 and the second driven link 8, so that the second support rod 7 is close to the ground and moves toward the tire 12, so that the second support rod 7 is placed under the tire 12;

[0028] Then, the output end of the electric push rod 4 is controlled to rise, driving the first support rod 6 to rotate outward, so that the second support rod 7 is lifted, and then the tire 12 is lifted synchronously, and maintenance operations on the tire 12 can be carried out;

[0029] Furthermore, in the present invention, the second support rod 7 can be rotated, and thus the tire 12 can be rotated during maintenance.
