Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbers and relates to a lifting ring connector and a shock absorber having the same. Background Art

[0002] The shock absorber is a component installed on an electric vehicle or motorcycle to reduce vibration and improve riding comfort. The structure of the shock absorber includes a hanging ring connector located at both ends and an elastic component arranged between the two hanging ring connectors. When in use, the two hanging ring connectors are respectively connected to the frame and the rear fork.

[0003] For example, a Chinese patent document discloses a shock absorber combined lifting ring (application number: 202122402764.1), which has a connecting part and a supporting part. One end of the connecting part has a connecting hole for realizing the connection and fixation of the shock absorber. The supporting part is arranged to protrude from the outer periphery of the connecting part, and an annular surface is provided on the outer end face of the supporting part for contacting the spring end in the shock absorber. The connecting part and the supporting part are split structures, the strength of the supporting part is greater than the strength of the connecting part, and a plug connector is provided at the other end of the connecting part. A supporting surface is formed on the connecting part at the root of the plug connector, and a through socket hole is provided on the supporting part. The socket hole is socketed on the plug connector, and the inner end face of the supporting part fits against the supporting surface.

[0004] The shock absorber combined lifting ring has the following shortcomings during use: the plug connector of the shock absorber combined lifting ring connection part is inserted into the socket hole of the support part. Since the shock absorber is in an inclined setting state during use, and the strength of the support part is greater than the strength of the connecting part, the support part will cause bump marks on the connecting part. As the use time increases, it is easy to cause damage to the lifting ring connector. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and to provide a lifting ring connector and a shock absorber having the same. The technical problem to be solved by the present invention is to improve the reliability of the lifting ring connector of the shock absorber.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A lifting ring connector includes a cylindrical main body, characterized in that the inner wall of the main body has an internal thread, an annular lifting ring is welded and fixed to the upper end of the main body, and a pressure plate is integrally formed at the lower end of the main body, and the lower end surface of the pressure plate is a plane.

[0008] The main body and pressure plate of this lifting ring connector are manufactured by integral molding, so that the overall mechanical properties of the main body and the pressure plate are consistent and the structural strength is significantly improved. The lifting ring is fixed to the upper end of the main body by welding, so that it is easy to manufacture an annular lifting ring and a cylindrical main body while taking into account the connection strength between the lifting ring and the main body. The inner wall of the main body is provided with an internal thread so that the lifting ring connector can be threadedly connected to the damper assembly, so that after the lifting ring connector is connected to the damper assembly, it can withstand large tensile and shear forces, is firm and reliable, has high connection strength and can achieve waterproof and dustproof effects. In addition, when the lifting ring connector is connected to the damper assembly, glue can be pre-coated on the internal thread of the main body to further enhance the firmness of the connection between the lifting ring connector and the damper assembly. At the same time, the lower end surface of the pressure plate is set to a plane, which can greatly increase the abutment area of the lifting ring connector after being connected to the damper assembly, thereby improving the reliability of the shock absorber lifting ring connector.

[0009] In the above-mentioned lifting ring connector, the main body, the lifting ring and the pressure plate are all made of iron material, the lifting ring and the pressure plate are formed into one piece by cold heading, and the surfaces of the main body, the lifting ring and the pressure plate are all provided with an electrophoretic paint coating layer. By making the main body, the lifting ring and the pressure plate all of iron material, the processing cost of the lifting ring connector can be reduced, and the lifting ring and the pressure plate are formed into one piece by cold heading, the processing accuracy and structural strength of the lifting ring connector can be enhanced. At the same time, the surfaces of the main body, the lifting ring and the pressure plate are all provided with an electrophoretic paint coating layer, so that the lifting ring connector has excellent corrosion resistance, can effectively resist chemical corrosion, water corrosion and weather corrosion, so that the lifting ring connector can still maintain a good appearance and performance in harsh environments, thereby improving the reliability of the shock absorber lifting ring connector, thereby reducing the processing cost of the lifting ring connector while making the lifting ring connector both reliable in use.

[0010] In the aforementioned lifting ring connector, the pressure plate portion is provided with a plurality of drainage holes along its circumference. The drainage holes connect the inside and outside of the shock absorber, allowing rainwater to flush away dust, sediment, and impurities accumulated within the shock absorber, thereby ensuring internal cleanliness of the shock absorber and reducing corrosion on the shock absorber end.

[0011] In the aforementioned lifting ring connector, the pressure plate portion has a positioning notch. The positioning notch serves as a reference for positioning when the lifting ring connector is connected to the damper assembly. Furthermore, when the lifting ring connector is covered with a dust cover, the positioning notch allows a positioning block on the dust cover to be inserted and positioned.

[0012] A shock absorber comprising a damper assembly and a shock absorbing spring sleeved thereon, characterized in that it further comprises the aforementioned lifting ring connector, wherein one end of the damper assembly is provided with a connecting post having an external thread, the main body of the lifting ring connector is threadedly connected to the connecting post, and the end surface of the pressure plate is disposed in contact with the end surface of the damper assembly. The shock absorber has good performance and a long service life.

[0013] Compared with the existing technology, the advantages of this lifting ring connector and the shock absorber having the same are: this lifting ring connector can reduce the production cost of the product while ensuring the reliability of the product, and can also improve the use effect and service life of the shock absorber having the same.
