Currently, frame-type all-aluminum car body structures of automobiles mainly use aluminum alloy profiles with various cut-off shapes, and in order to install a certain part, threaded sleeves are usually riveted and welded on tubular aluminum profiles of cavities. The traditional thread sleeve is formed by riveting one end of an aluminum profile on the upper surface and the lower surface and welding one end of the aluminum profile. In the running process of the automobile, the welding seam of the sleeve is easy to crack due to vibration of the automobile, and finally the threaded sleeve rotates to fail. Accordingly, there is a need for further improvements.
In one aspect, the application provides a connection structure of an all-aluminum vehicle body and a threaded sleeve, which comprises a vehicle body section bar 100 and a mounting hole 110 penetrating the vehicle body section bar 100; a threaded sleeve 200, which is mounted to the mounting hole 110 in a first direction by being riveted thereto; the limiting assembly 300 comprises a limiting protrusion 310 and a limiting groove 320 matched with the limiting protrusion 310; one of the limiting protrusion 310 and the limiting groove 320 is disposed on the outer wall 210 of the threaded sleeve 200, and the other is disposed on the inner wall 111 of the mounting hole 110, so that the threaded sleeve is installed in the mounting hole 110 in a riveting manner, and the limiting protrusion 310 can be embedded into the limiting groove 320 for limiting the relative rotation of the threaded sleeve and the vehicle body profile 100.
It can be appreciated that in this connection structure, by arranging the limiting component 300 at the connection position between the threaded sleeve 200 and the vehicle body profile 100, the threaded sleeve 200 on the riveted vehicle body profile 100 can enable the limiting protrusion 310 in the limiting component 300 to be embedded into the limiting groove 320 to limit the relative rotation between the threaded sleeve 200 and the vehicle body profile 100, so as to effectively improve the fixity between the threaded sleeve 200 and the vehicle body profile 100, and prevent the connection performance between the threaded sleeve and the vehicle body profile 100 from being affected by vibration generated during running of the vehicle.
In some embodiments, the threaded sleeve 200 includes an extension edge 220 provided at an end thereof, the extension edge 220 extending along an outer contour of the threaded sleeve 200 in a direction away from an axis thereof, and a first mounting surface 230 formed on a side of the extension edge 220 in a first direction.
It will be appreciated that the provision of the extension edge 220 can be used to limit the riveting process in a first direction for determining the depth of the rivet on the body profile 100 of each threaded sleeve 200, and that the provision of the extension edge 220 can also be used to distinguish between the reverse and the forward of the threaded sleeve 200 to ensure consistency of the threads in the threaded sleeve 200.
In some embodiments, the body profile 100 includes a second mounting surface 120 along one side of the first direction, and the mounting hole 110 includes a countersink 112 formed by recessing the second mounting surface 120 into the first direction, with a projection of the extension in the first direction coinciding with a contour of the countersink 112.
In some embodiments, the projection of the extension edge 220 in the first direction is circular or polygonal.
It will be appreciated that the projection of the extension edge 220 in the first direction may be a circular structure or a multi-shape structure, the circular structure may conform to the outer wall 210 of the threaded sleeve 200, and the septum may be more convenient and faster during the manufacturing process. The polygonal arrangement is such that the extension edge 220 is fully embedded into the countersink 112, and the polygonal mechanism is used to assist the limiting assembly 300 in limiting the relative rotation of the threaded sleeve 200 and the body profile 100.
In some embodiments, the thickness of the extension edge 220 along the first direction is equal to the height of the countersink 112 along the first direction, so that the first mounting surface 230 is spliced and overlapped with the second mounting surface 120 after the threaded sleeve 200 is riveted to the mounting hole 110.
It can be appreciated that the provision of the countersink 112 in the body profile 100 provides an accommodating space for the extension portion, so that the threaded sleeve 200 can be completely accommodated in the countersink 112 after being mounted on the body profile 100, thereby ensuring the flatness of the first mounting surface 230 of the threaded sleeve 200 and the second mounting surface 120 of the body profile 100, and avoiding the influence on the mounting of the subsequent structure due to the press-fitting of the threaded sleeve 200.
In some embodiments, the limiting assemblies 300 are provided in a plurality, and the limiting assemblies 300 are symmetrically distributed or circumferentially equidistantly distributed at the connection between the body profile 100 and the threaded sleeve 200.
It can be appreciated that referring to fig. 3 and 5, fig. 6 and 7 are schematic diagrams of structures in which the limiting assemblies 300 are circumferentially distributed, and fig. 6 and 7 are schematic diagrams of structures in which the limiting assemblies 300 are symmetrically distributed, and the symmetrical or circumferentially distributed arrangement can make the connection between the threaded sleeve 200 and the body profile 100 be more balanced in axial stress during riveting, so as to avoid the phenomenon of offset during riveting, and in addition, make the stress of each limiting assembly 300 more uniform during the relative rotation of the threaded sleeve 200 and the body profile 100.
In some embodiments, the limiting protrusion 310 is disposed on the outer wall 210, the limiting groove 320 is disposed on the inner wall 111, and the limiting protrusion 310 is slidably disposed in the limiting groove 320 along the first direction.
It can be appreciated that in the process of press-fitting the threaded sleeve 200, the limit protrusion 310 and the limit groove 320 are corresponding to each other, the width of the limit groove 320 is slightly greater than the width of the limit protrusion 310 by about 0.3-0.8mm, such arrangement can ensure that the limit protrusion 310 can smoothly slide in the limit groove 320, and a certain margin is left, and such arrangement can prevent deformation of the limit protrusion 310 and the limit groove 320 caused by excessive friction between the limit protrusion 310 and the limit groove 320 in the riveting process from affecting the final limit effect.
In some embodiments, the limit protrusion 310 extends from a side of the extension edge 220 facing away from the first mounting surface 230 in the first direction to an end surface of the threaded sleeve 200 facing away from the extension edge 220, and the limit groove 320 penetrates the inner wall 111 in the first direction.
It can be appreciated that, the arrangement that the limit protrusion 310 extends from the extending edge 220 to the other side of the threaded sleeve 200 along the first direction can enable the limit protrusion 310 to slide in the limit groove 320, so that no jamming occurs when the limit protrusion 310 is abutted with the limit groove 320 due to the multiple segments. The penetrating arrangement of the limiting groove 320 can ensure smooth riveting of the two when the thickness of the vehicle body profile 100 is smaller than that of the threaded sleeve 200.
In some embodiments, the difference between the outer diameter of threaded sleeve 200 and the inner diameter of mounting hole 110 is 0.5-0.8mm.
It can be appreciated that, since the threaded sleeve 200 is riveted on the body profile 100, the outer diameter of the threaded sleeve 200 is slightly larger than the inner diameter of the mounting hole 110, and the difference between the outer diameter of the threaded sleeve 200 and the inner diameter of the mounting hole 110 is controlled to be between 0.5 mm and 0.8mm, so that the strength of the threaded sleeve 200 and the body profile 100 after being riveted together can be maintained, and the pressure in the riveting process can be effectively saved.
In a second aspect, embodiments of the present application provide a vehicle chassis assembly comprising a connection structure as in any one of the preceding claims.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and not for limiting the same; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application, and are intended to be included within the scope of the appended claims and description.
