Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an end cover for a vehicle chassis. Background Technology

[0002] In vehicle bodies and areas requiring a certain level of rigidity and strength for support, flat metal sheets are typically processed using stamping techniques to obtain sheet metal stamping parts that match the vehicle body shape and possess good physical properties. However, due to their inherent shape, some sheet metal stamping parts are prone to springback and misalignment during use, leading to reduced precision in the fit between the stamping parts and the vehicle body, severely impacting their application in vehicle assembly. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides an end cover for a vehicle chassis, including an end cover body, an end cover shaft hole and a connection port for engaging with a vehicle chassis through the end cover body, and flanged bosses on both sides of the end cover shaft hole on the end cover body, so as to guide the end cover body to be installed on the chassis and ensure the fitting accuracy between the end cover body and the vehicle chassis.

[0004] Preferably, the flange boss is formed as a protrusion protruding from the end cap body and a groove recessed into the end cap body, so that the end cap body can fit more precisely into the chassis.

[0005] Preferably, the end cap body and the flanged boss are integrally formed by stamping, thereby ensuring the consistency of the shape of the end cap body.

[0006] Preferably, a transition arc surface is provided on the end cap body along the connection port to effectively reduce stress concentration on the end cap body and improve its service life.

[0007] Preferably, the diameter of the end cap shaft hole is 40 mm.

[0008] Preferably, a drainage hole is also provided on the surface of the end cap body to drain water accumulated at the joint of the components, thereby effectively extending its service life.

[0009] Preferably, the diameter of the drain hole is 3mm.

[0010] Preferably, the end cap body has a flat elliptical shape.

[0011] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: This application has an end cap body with an end cap shaft hole and a connection port for engaging with the vehicle chassis. Flanged bosses are also provided on both sides of the end cap shaft hole. The end cap shaft hole allows the mounting shaft at the vehicle chassis to be guided and installed. The connection port and the flanged bosses on both sides of the end cap shaft hole allow the end cap body to better fit the vehicle chassis through the connection port. The flanged bosses guide the assembly of components that fit against the surface of the vehicle chassis, effectively preventing springback and misalignment, ensuring the fitting accuracy between the two, and enabling the end cap body to be guided and installed onto the chassis, thus ensuring the fitting accuracy between the end cap body and the vehicle chassis.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example

[0018] To address the aforementioned technical problems, this embodiment provides an end cover for a vehicle chassis, such as... Figure 1As shown, the device includes an end cap body 10, through which an end cap shaft hole 11 and a connection port 12 for engaging with the vehicle chassis are provided. Flanged bosses 13 are also provided on both sides of the end cap shaft hole 11. The end cap shaft hole 11 allows the mounting shaft at the vehicle chassis to be guided and installed. The connection port 12 and the flanged bosses 13 on both sides of the end cap shaft hole 11 allow the end cap body 10 to better fit the vehicle chassis via the connection port 12. The flanged bosses 13 guide the assembly of components that fit against the surface of the vehicle chassis, effectively preventing springback and misalignment, ensuring the precision of the fit between the two components, and enabling the end cap body 10 to be guided and installed onto the chassis, thus ensuring the precision of the fit between the end cap body 10 and the vehicle chassis.

[0019] Specifically, such as Figure 2 As shown, the flanged boss 13 is formed as a protrusion protruding from the end cover body 10 and a recessed groove into the end cover body 10. By designing the flanged boss 13 as a protrusion protruding from the end cover body 10 and a recessed groove into the end cover body 10, its shape can match the parts on the surface of the vehicle chassis. Thus, during the installation of the end cover body 10, the flanged boss 13 can guide the installation, thereby ensuring the fitting accuracy between the end cover body 10 and the vehicle chassis, and enabling the end cover body 10 to fit more precisely against the chassis.

[0020] In the above scheme, the end cap body 10 and the flipped boss 13 are integral stamped parts. By designing the end cap body 10 and the flipped boss 13 as integral stamped parts, the processing steps can be effectively reduced, thereby effectively improving the production efficiency. Furthermore, the welding and splicing processes can be avoided to ensure the stability of its size and shape, thus ensuring the consistency of the shape of the end cap body 10.

[0021] Furthermore, a transition arc surface is provided at the connection port 12 along the end cap body 10. By providing a transition arc surface at the connection port 12 along the end cap body 10, the rigidity of the connection can be effectively improved, thereby enhancing the overall structural stability of the end cap body 10, effectively reducing stress concentration in the end cap body 10, and improving its service life.

[0022] In a preferred embodiment, the diameter of the end cap shaft hole 11 is 40 mm.

[0023] Specifically, a drainage hole 14 is provided on the surface of the end cap body 10 to drain water accumulated at the joint of the parts, effectively extending its service life.

[0024] Furthermore, the diameter of the drain hole 14 is 3mm.

[0025] In the above scheme, the end cap body 10 has a flat elliptical shape. By adopting the flat elliptical shape design of the end cap body 10, the structural design of the end cap body 10 is more compact, and the surface stress can be effectively and evenly distributed, reducing local stress concentration and enhancing structural strength.

[0026] In summary, in one or more embodiments of this application, this application provides an end cover for a vehicle chassis, including an end cover body. The end cover body has a through-hole and a connection port for engaging with the vehicle chassis frame. Flanged bosses are also provided on both sides of the end cover shaft hole. The end cover shaft hole allows the mounting shaft at the vehicle chassis to be guided and installed through it. The connection port and the flanged bosses on both sides of the shaft hole allow the end cover body to better fit the vehicle chassis through the connection port. The flanged bosses guide the assembly of components that fit against the surface of the vehicle chassis, effectively preventing springback and misalignment, ensuring the fitting accuracy between the two, and enabling the end cover body to be guided and installed onto the chassis, thus ensuring the fitting accuracy between the end cover body and the vehicle chassis.

[0027] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
