Abstract
The utility model discloses a projection welding bolt and an automobile with the projection welding bolt. The projection welding bolt comprises a base and a bolt body connected with the base. A projection welding point and a sealing rib are arranged on the portion, close to the bolt body, of the side face of the base. The height difference between the sealing rib and the projection welding point is within the preset threshold range. The projection welding point and the sealing rib are arranged on the portion, close to the bolt body, of the side face of the base; after the projection welding point is welded, the sealing rib makes contact with the welding face of a steel plate, and therefore the sealing effect is achieved. The sealing rib is arranged between the base and the welded steel plate to serve as a supporting object, and therefore strength of a welding part is increased.
Description
Technical field
The utility model relates to automobile technical field, particularly relates to a kind of projection welding bolt and has the automobile of this projection welding bolt.
Background technique
Along with social development, people are also more and more higher to the requirement of automobile, and from basic safety, stable performance aspect progressively requires comfort level aspect, for example the requirement of NVH performance.Wherein, sealing is very large to the contribution of NVH, and in body in white structure, bearing surface projection welding bolt consumption is very large, and the sealing at these bolt places is very important.
But, projection welding bolt on automobile body-in-white does not possess sealing configuration at present, after being welded on body in white due to the impact of the relation of its structure and the quality of the face of weld of body in white own, sealing is very poor, in addition the consumption of projection welding bolt inside and outside isolated passenger cabin is large, so just need a kind of projection welding bolt of good airproof performance.
Model utility content
In order to solve the not good problem of existing projection welding bolt sealing effect, the utility model provides a kind of projection welding bolt and has had the automobile of this projection welding bolt.
The technical solution adopted in the utility model is: a kind of projection welding bolt, comprise base and the double-screw bolt being connected with base, described base is being provided with projection welding point and sealed muscle near on the side of double-screw bolt, and the difference of the height of described sealed muscle and projection welding point is positioned at predetermined threshold scope.
Preferably, described sealed muscle is looped around described double-screw bolt around.
Preferably, described sealed muscle is arranged between projection welding point and double-screw bolt.
Preferably, described sealed muscle is arranged on the periphery of projection welding point.
Preferably, described sealed muscle is convex.
Preferably, described sealed muscle is more than two or two.
Preferably, described projection welding point is more than three or three.
Preferably, the height of described projection welding point is greater than the height of described sealed muscle.
The utility model also provides a kind of automobile, comprises described projection welding bolt and steel plate, described projection welding bolt by described projection welding spot welding on steel plate.
The beneficial effects of the utility model are: projection welding bolt of the present utility model is being provided with projection welding point and sealed muscle near on the side of double-screw bolt, and after projection welding spot welding, sealed muscle contacts with the face of weld of steel plate, thereby plays sealing effect.Owing to thering is sealed muscle as supporter between base and welding steel, also increased the intensity of weldment.Projection welding bolt of the present utility model can guarantee good sealability, and projection welding bolt manufacture cost is not high, can extensive use, and projection welding bolt has guaranteed sealing while being welded on automobile.

Embodiment
For making the technical problems to be solved in the utility model, technological scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As Figure 1-4, projection welding bolt for a kind of embodiment of the utility model, this projection welding bolt comprises base 1 and the double-screw bolt 5 being connected with base, described base 1 is being provided with projection welding point 2 and sealed muscle 4 near on the side of double-screw bolt, and described sealed muscle 4 is positioned at predetermined threshold scope with the difference of the height of projection welding point 2.Wherein, the side of projection welding point is set is face of weld 3 to base 1.
Projection welding bolt of the present utility model is being provided with projection welding point and sealed muscle near on the side of double-screw bolt, and after projection welding spot welding, sealed muscle contacts with the face of weld of steel plate, thereby plays sealing effect.Owing to thering is sealed muscle as supporter between base and welding steel, also increased the intensity of weldment.
Sealed muscle 4 of the present utility model is positioned at predetermined threshold scope with the difference of the height of projection welding point 2, and this threshold value can arrange as required.Preferably, the height of sealed muscle is less than the height of projection welding point, and when projection welding point welds thawing, sealed muscle contacts with the face of weld of steel plate, has played the effect of compacting face of weld.
Again consult Fig. 1, sealed muscle 4 of the present utility model is looped around described double-screw bolt 5 around, is arranged between projection welding point and double-screw bolt.Sealed muscle of the present utility model can be one or more of, is convex.The projection welding point of the present embodiment is more than three or three, is evenly distributed on face of weld.Certainly, sealed muscle also can be arranged on the periphery of projection welding point.
As shown in Figure 2, the projection welding of the present embodiment point is 3, has the sealed muscle 4 of a circle projection at the inner ring of projection welding point 2, the face of weld compacting of sealed muscle and steel plate after welding, thus play sealing effect.The height of the sealed muscle 4 of the present embodiment is less than projection welding point 2 height.
Fig. 4 is the sectional view after projection welding bolt welding of the present utility model, as shown in Figure 4, projection welding bolt is when starting with steel plate 6 welding, projection welding bolt is put 2 with steel plate 6 by projection welding and is contacted, and after turn-on current, projection welding point 2 starts to melt, along with the fusion of face of weld and the steel plate 6 of projection welding bolt, the sealed muscle 4 being positioned on face of weld contacts with the face of weld of steel plate 6, flatness by steel plate 6 determines the fusion degree of sealed muscle 4 herein, as flatness well merge more, can guarantee sealability; As out-of-flatness, will there is partial fusion, not merging part can tightly be pressed on steel plate, forms seal ring.Finally reach the requirement that meets different conditions steel plate sealing herein.
Embodiment of the present utility model is only schematic; rather than restrictive; those skilled in the art is under the enlightenment of this method; do not departing from the scope situation that this method aim and claim protect; can also make a lot of distortion, within these all belong to protection domain of the present utility model.
