[0002] Car carriers are specialized transport vehicles used to transport cars, commercial vehicles, exhibition vehicles, and test vehicles, playing a key role in the automotive logistics industry chain.

[0003] A search revealed existing car carrier protection mechanisms, such as the one disclosed in CN222329573U for a center-axle car carrier. This structure nests a positioning plate and a pressing plate on the side of a support plate. The support plate, along with a limiting plate, is embedded in a groove formed by a limiting block and the top of a support shaft. The positioning plate is also embedded in the positioning groove. While this provides support from the support shaft and transverse shaft at the middle and both ends of the support plate, thus forming a stable load-bearing structure, the lengths of the protective rods and fixing rods are fixed. This means that the length cannot be adjusted according to the height and length of different types of vehicles, resulting in poor applicability. Therefore, a new protection structure for a center-axle car carrier is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3 A protective structure for a center-axle car carrier includes a base plate 1, a rectangular block 2 fixedly connected to the top of the base plate 1, a rectangular cavity formed in the rectangular block 2, a rectangular shell 3 above the rectangular block 2, a first gear 4 inside the rectangular cavity, a first rack 5 inside the rectangular cavity, and a lifting mechanism inside the rectangular cavity that drives the rectangular shell 3 to rise via the first gear 4 and the first rack 5. By rotating the first gear 4, the first rack 5 inside the cavity is driven to rise, and the first rack 5 then drives the rectangular shell 3 above to rise, thereby raising the car according to the height of the vehicle being transported.

[0022] The rectangular shell 3 has a first set of rods 6 on both sides. The first set of rods 6 consists of an outer rod and an inner rod. The inner rod is located inside the outer rod, and one end of the inner rod is fixedly connected to a limit block. The limit block is slidably connected to the inner wall of the outer rod, which can prevent the inner rod from coming out of the outer rod.

[0023] The rectangular shell 3 is provided with a second rack 7 and a third rack 8. The rectangular shell 3 is provided with an adjustment mechanism that drives the first sleeve rod 6 to extend and retract through the second rack 7 and the third rack 8. By moving the second gear 14 and the second rack 7, the first sleeve rod 6 on both sides can move to the sides, which can be adjusted according to the length of the transported vehicle.

[0024] The lifting mechanism includes a first rotating rod 10 rotatably connected to one side of the rectangular block 2. One end of the first rotating rod 10 is fixedly connected to the first gear 4. A U-shaped plate 11 is fixedly connected to the bottom of the rectangular shell 3. The U-shaped plate 11 is fixedly connected to the first rack 5. The first gear 4 meshes with the first rack 5. The first rotating rod 10 drives the first gear 4 to rotate. The first gear 4 then drives the first rack 5 on one side of the U-shaped plate 11 to rise. The top of the rectangular block 2 has an opening. The rack then drives the U-shaped plate 11 to move out of the rectangular cavity, thereby driving the rectangular shell 3 to rise. The rectangular shell 3 can drive the first sleeve rods 6 on both sides to extend.

[0025] A first limiting plate 12 is fixedly connected to the bottom of the U-shaped plate 11. The first limiting plate 12 is slidably connected to the rectangular cavity. The first limiting plate 12 can limit the U-shaped plate 11 and prevent the U-shaped plate 11 from completely coming out of the rectangular cavity.

[0026] The adjustment mechanism includes a second rotating rod 13 rotatably connected to one side of the rectangular shell 3. A second gear 14 is fixedly connected to one end of the second rotating rod 13. The second gear 14 meshes with the second rack 7 and the third rack 8 respectively. The first sleeve rods 6 on both sides are fixedly connected to the second rack 7 and the third rack 8 respectively. The rotation of the second rotating rod 13 causes the second rack 7 and the third gear to move out of the rectangular shell 3, thereby causing the first sleeve rods 6 on both sides to move away from each other, which can protect longer transported vehicles.

[0027] A rectangular plate 15 is fixedly connected to the bottom of the rectangular shell 3. A second sleeve rod 16 is fixedly connected to one side of the rectangular plate 15. One end of the second sleeve rod 16 is fixedly connected to the first sleeve rod 6. The second sleeve rod 16 between the rectangular plate 15 and the first sleeve rod 6 can move as the first sleeve rod 6 extends or shortens to block and protect the transported vehicle. The second sleeve rod 16 has the same structure as the first sleeve rod 6, consisting of an outer rod and an inner rod.

[0028] The rectangular shell 3 has rectangular openings at both ends. The second rack 7 and the third rack 8 are located inside the rectangular openings. The second rack 7 and the third rack 8 only have teeth at the end closest to the second gear 14. The rectangular openings allow the toothless ends of the second rack 7 and the third rack 8 to extend from inside the rectangular shell 3 to outside the rectangular shell 3. The rectangular openings are close to the second rack 7 and the third rack 8, limiting the second rack 7 and the third rack 8 so that the second rack 7 and the third rack 8 can always mesh with the second rack 7.

[0029] A sliding block 17 is fixedly connected to the bottom of the first rod 6. A sliding groove 18 is provided on the base plate 1. The sliding block 17 is slidably connected to the sliding groove 18. The sliding block 17 and the sliding groove 18 limit the first rod 6, so that the second rack 7 and the third rack 8 at one end of the first rod 6 are always meshed with the second gear 14.

[0030] A limiting groove is provided in the sliding groove 18. A second limiting plate is fixedly connected to one side of the sliding block 17. The second limiting plate is slidably connected to the limiting groove. The limiting groove and the second limiting plate limit the sliding block 17 to prevent the sliding block 17 from falling out of the limiting groove when the rectangular shell 3 rises and drives the first sleeve rod 6 to extend.

[0031] The lifting mechanism also includes a first drive motor 9 installed on one side of the rectangular block 2, and the adjustment mechanism also includes a second drive motor installed on one side of the rectangular shell 3.

[0032] The specific model and specifications of the first drive motor 9 and the second drive motor need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0033] The working principle of this utility model:

[0034] When the size of the vehicle being transported is large, the first drive motor 9 drives the first rotating rod 10 to rotate, the first rotating rod 10 drives the first gear 4 to rotate, the first gear 4 then drives the first rack 5 on one side of the U-shaped plate 11 to rise, the rack then drives the U-shaped plate 11 to move out of the rectangular cavity, thereby driving the rectangular shell 3 to rise, and the rectangular shell 3 can drive the first sleeve rods 6 on both sides to extend.

[0035] Subsequently, the second drive motor drives the second rotating rod 13 to rotate, the second rotating rod 13 drives the second gear 14 to rotate, the second gear 14 drives the second rack 7 and the third rack 8 to gradually move out of the rectangular shell 3, the second rack 7 and the third rack 8 respectively drive the first sleeve rods 6 on both sides to move away from each other, the first sleeve rods 6 then drive the second sleeve rod 16 to extend, the extended first sleeve rod 6 and the second sleeve rod 16 protect the transported vehicle.
