The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Example 1
Referring to fig. 1 to 4, a block-type wheel cover structure according to an embodiment of the present utility model includes a wheel cover body 100, and a first extension plate 200 and a second extension plate 300 disposed on opposite sides of the wheel cover body 100, wherein:
in order to improve the conventional integrated wheel cover into the block-type wheel cover, a first flange 110, a second flange 120 and a third flange 130 are respectively provided at the edges of the wheel cover body 100. The first flange 110, the second flange 120 and the third flange 130 are used for overlapping with other peripheral components to achieve the receiving effect of the wheel cover. The two ends of the second flange 120 are respectively provided with a first connecting portion 121 and a second connecting portion 122, the first connecting portion 121 is used for connecting the first extension board 200, and the second connecting portion 122 is used for connecting the second extension board 300.
The first extension board 200 includes a first welding edge 210, a second welding edge 220, and a first anti-cutting edge 230, so that in order to make the first anti-cutting edge 230 and the second flange 120 be gently connected, an included angle at a connection position of the first welding edge 210 and the second welding edge 220 is not less than 90 °, and when an included angle between the first welding edge 210 and the second welding edge 220 is an obtuse angle, an arc of the first anti-cutting edge 230 is smaller, so that the first anti-cutting edge is gently connected with the second flange 120. When the radian of the wheel cover structure is smaller, the plane with abrupt change in the stamping forming process can be reduced as much as possible, and defects are avoided. Meanwhile, the radian of the wheel cover is reduced, so that stress can be dispersed, and damage to the structure of the wheel cover caused by stress concentration is avoided.
Further, in order to connect the first extension plate 200 with the wheel cover body 100, a plurality of welding bosses 400 are disposed at the middle portion of the first extension plate 200 and along the first welding edge 210 and the second welding edge 220, and the first extension plate 200 is welded with the second flange 120 through the welding bosses 400, so that the first extension plate 200 is attached to the second flange 120. Meanwhile, the connection hole 500 formed in the first extension plate 200 is aligned with the connection hole 500 formed in the second flange 120, so that the second flange 120 overlaps the peripheral member.
The second extension plate 300 is disposed at an end of the second flange 120 away from the first extension edge, and the second extension plate 300 includes a third welding edge 310, a fourth welding edge 320, and a second anti-cutting edge 330. In order to fit the end of the second flange 120, an external corner 340 extends from the middle of the second extension plate 300. The external corner 340 is fixed at the corner of the wheel housing body 100.
Similarly, welding bosses 400 are provided along the third welding edge 310 and the middle of the second extension plate 300, and the second extension plate 300 is welded to the wheel cover body 100 and the second flange 120 by the welding bosses 400, so that the second anti-cutting edge 330 is gently connected with the second flange 120. The radian of the wheel cover structure is reduced, the plane with abrupt change in the stamping forming process is reduced, and defects are avoided. Meanwhile, the radian of the wheel cover is reduced, so that stress can be dispersed, and damage to the structure of the wheel cover caused by stress concentration is avoided.
Further, a process notch 350 is disposed on the fourth welding edge 320 near the external corner 340. In this embodiment, the process notch 350 can avoid forming cracking when the wheel cover body 100 is formed by stamping. Because when the concentrated stress to which the wheel cover body 100 is subjected reaches the yield strength of the material, the region near the root of the notch is caused to plastically deform. And the process notch 350 changes the stress state in front of the second extension plate 300, so that the stress applied to the second extension plate is changed from unidirectional stretching to bidirectional or three-directional stretching, and the strength of the second extension plate is improved. When the second extension plate 300 is welded to the wheel housing body 100, the coupling holes 500 provided thereon are aligned with the coupling holes 500 provided on the second coupling part 122.
It should be noted that in this embodiment, the part on one side of the welding spot area where the wheel cover body 100 is overlapped with the first extension plate 200 or the second extension plate 300 needs to be made into a round or rectangular sinking table, the other side of the welding spot area keeps a plane, the narrowest part of the sinking table is not less than 16mm, so that welding cannot be performed, and a gap of 0.5mm needs to be reserved in other overlapping areas, so that abnormal noise caused by vibration is avoided.
In summary, according to the above-mentioned sectional type wheel casing structure, divide into wheel casing body, first extension board and second extension board with the wheel casing, replace traditional integral type structure, through using first extension board and second extension board to be connected with the car to with first extension board and second extension board and wheel casing body welding, replace the defect when stamping forming with welded connection, strengthened the steadiness of wheel casing. Specifically, the blocking type wheel casing structure includes the wheel casing body and locates the first extension board and the second extension board of the relative both sides of wheel casing body, wheel casing body edge is equipped with first turn-ups, second turn-ups and third turn-ups, and first turn-ups and third turn-ups are used for being connected with other peripheral spare, are equipped with on the second turn-ups to be used for the first connecting portion of being connected with first extension board and be used for the second connecting portion of being connected with the second extension board, and first extension board and second extension board all pass through welded fastening with the second turn-ups, have overcome traditional stamping forming and have led to the junction to pucker or the defect of fracture, have strengthened the steadiness of wheel casing.
