Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a lightweight pressing plate structure. Background Art

[0002] Lightweighting of automobiles means reducing the curb weight of automobiles as much as possible while ensuring the strength and safety of automobiles, thereby improving the power of automobiles, reducing fuel consumption and reducing exhaust pollution. As we all know, most cars will have a spare tire (hereinafter referred to as spare tire), and its specifications will be the same as those of the original automobile tires. The main function of automobile spare tires is that during long-distance driving, tire blowouts and other damage failures are inevitable. At this time, the spare tire can be taken out and installed to replace the blown tire. The spare tire is generally fixed to the car through a spare tire pressure plate. The spare tire pressure plate generally includes a plate body and a screw. During use, the screw is passed through the center hole of the spare tire wheel and screwed into the nut welded at the rear of the car body to tighten it to fix the spare tire.

[0003] However, the existing spare tire pressure plate is a solid plate with a relatively thick thickness, which makes the existing pressure plate heavy, which is not conducive to reducing the weight of the car in today's lightweight automobile market.

[0004] Therefore, the utility model provides a lightweight pressure plate structure to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model designs a lightweight pressure plate structure, which aims to solve the technical problem of the heavy weight of the spare tire pressure plate in the prior art.

[0008] As a preferred solution of the utility model, four groups of vertical plates are fixedly connected to the inner side of the positioning ring, and a sleeve tube is fixedly connected to the middle of the four groups of vertical plates, and the sleeve tube is sleeved on the outer side of the fastening bolt.

[0009] As a preferred solution of the utility model, the nut at the top end of the fastening bolt is configured as a hexagonal type, and a hexagonal hole is provided at the center of the top end of the fastening bolt.

[0010] As a preferred solution of the utility model, both front and rear ends of the screw-on cap are fixedly connected with side ears, and the lengths of the front and rear ends of the two groups of side ears are greater than the inner diameter of the positioning ring.

[0011] As a preferred solution of the utility model, the plurality of reinforcement plates are radially distributed on the outside of the positioning ring, and the heights of the plurality of reinforcement plates are flush with the top of the positioning ring.

[0012] As a preferred solution of the utility model, an embedding hole is opened at the center of the top of the tightening cap, the nut at the top of the fastening bolt is embedded in the embedding hole, and a circular protrusion is fixedly connected to the bottom of the tightening cap.

[0013] As a preferred solution of the utility model, a circular groove is opened at the center of the sleeve tube, the inner diameter of the circular groove is equal to the outer diameter of the circular protrusion, and a rubber gasket is sleeved on the outside of the fastening bolt and inside the circular groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is designed with a circular flat plate, a positioning ring and a fastening bolt. During use, the fastening bolt is first passed through the sleeve, and then the fastening bolt is passed through the center hole of the spare tire wheel and screwed into the nut welded on the rear of the vehicle body. Then, it is manually tightened through the side ears at the front and rear ends of the tightening cap, or the fastening bolt is tightened by a hexagonal electric wrench through the hexagonal hole opened at the center of the top of the fastening bolt. When the fastening bolt is tightened, the circular protrusion and the rubber gasket will be continuously pushed into the interior of the circular groove, and then the circular protrusion and the rubber gasket will push the sleeve, thereby pushing the four groups of vertical plates and the positioning ring, and the positioning ring will push the circular flat plate to press downward to fix the spare tire. The plurality of circular holes can reduce the weight of the circular flat plate without affecting the strength of the circular flat plate when it is pressed downward. The supporting structure of the four groups of vertical plates is firm and uses less material. The combination of the reinforcement plate and the positioning ring can increase the overall strength of the circular flat plate. Under this premise, the thickness of the circular flat plate can be reduced, so that the circular flat plate is lighter in weight while ensuring strength. BRIEF DESCRIPTION OF THE DRAWINGS

The four groups of vertical plates 7 are evenly distributed on the inner side of the positioning ring 2 to support and fix the sleeve tube 8. The supporting structure of the four groups of vertical plates 7 is firm and uses less material. The sleeve tube 8 is sleeved on the outer side of the fastening bolt 3.

[0026] For further information, see Figure 1 , Figure 3 and Figure 4The nut at the top of the fastening bolt 3 is set to be hexagonal, and the hexagonal nut makes the connection between the fastening bolt 3 and the tightening cap 4 more secure.
