Abstract
The utility model discloses a special bolt for installing a spoiler. The bolt is provided with a bolt seat and a bolt head, wherein the bolt seat is used for fixedly connecting the back face of the spoiler, the bolt head is fixedly connected with a right reinforcing plate of an automobile back door hinge, and an annular limiting boss is arranged between the bolt seat and the bolt head. The special bolt for installing the spoiler is used with a standard component hexagon flange nut in a matching mode, enables a spoiler body to be fixed on the reinforcing plate of the back door hinge, enhances the stability of the bolt and a fixed joint, avoids the phenomenon of looseness of the bolt, and therefore fastness of the installation of the spoiler is enhanced. The special bolt for installing a spoiler uses a pre-buried method, thereby effectively raising the performances such as mechanical strength, rigidity, conductivity of the spoiler. At the same time, the design of the special bolt not only enables materials of the spoiler body to be obviously reduced, but also saves development and design cost of a set of back door outer plate mould for automobile body metal plates.
Description
Technical field
The utility model relates to automobile spoiler, and particularly a kind of spoiler is installed special bolt.
Background technique
Automobile spoiler (Slingshot Autosculpt) refers to the add-in card installed above the tailstock, be also referred to as automobile tail fin, its Main Function is in order to reduce the lift of vehicle tail, if tailstock lift is larger than headstock lift, just easily cause car to turn to too much, the trailing wheel earth-grasping force reduces, high stability is poor, if and install spoiler additional, just can utilize the inclination of spoiler, wind power direct is practiced midwifery give birth to downward pressure, the trailing wheel earth-grasping force is increased, thereby the riding stability of automobile is improved.And traditional spoiler mounting type mainly contains two kinds of stick type and bolt fastenings, but stick type is insecure, therefore generally adopts bolt fastening.The general fixedly bolt head of the bolt of spoiler is linear, and the surface of contact of bolt head and fixed connection point is little, and is easily loosening, poor stability, thereby the spoiler soundness that causes installing is not very high, and tailgate outside plate stamping processes need to increase the pass forming die operation, and input cost is larger.
Therefore need to improve traditional technique, increase the area of contact of bolt head and fixed connection point, strengthen stability, thereby ensure the soundness of the spoiler of installing.
The model utility content
In view of this, this use is novel to provide a kind of spoiler that special bolt is installed, improve by the structure to bolt, strengthen the stability of bolt and fixed connection point, avoid bolt that loosening phenomenon occurs, thereby the installation soundness of spoiler, and then mechanical strength, hardness, electric conductivity of spoiler body etc. have effectively been improved, simultaneously, the design of this special bolt, not only make the materials of spoiler body that obvious minimizing has been arranged, and concerning vehicle body sheet metal, saved especially the mould development design cost of a cover tailgate outside plate.
Spoiler of the present utility model is installed special bolt, described bolt is provided with for the bolt block that is fixedly connected with the spoiler back side and the bolt head that is fixedly connected with the right stiffening plate of car body backdoor hinge, is provided with the annular stop boss between described bolt block and the bolt head;
Further, described bolt block cross section is square structure;
Further, described bolt block edges and corners are provided be used to the R angle that seamlessly transits;
Further, described annular stop boss cross section is isosceles trapezoid;
Further, described bolt is the M6 bolt.
The beneficial effects of the utility model: spoiler of the present utility model is installed special bolt, be used in conjunction with the standard piece hexagon nut with flange, the spoiler body is fixed on the backdoor hinge stiffening plate, strengthen the stability of bolt and fixed connection point, avoid bolt that loosening phenomenon occurs, thus the installation soundness of spoiler; This kind special bolt adopts pre-buried mode, mechanical strength, hardness, electric conductivity of spoiler body etc. have effectively been improved, simultaneously, the design of this special bolt, not only make the materials of spoiler body that obvious minimizing has been arranged, and concerning vehicle body sheet metal, saved especially the mould development design cost of a cover tailgate outside plate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model assembling.
Embodiment
Fig. 1 is structural representation of the present utility model, Fig. 2 is the structural representation after the utility model assembling, as shown in the figure: the spoiler of the present embodiment is installed special bolt, described bolt is provided with for the bolt block 1 that is fixedly connected with the spoiler back side and the bolt head 3 that is fixedly connected with the right stiffening plate of car body backdoor hinge, is provided with annular stop boss 4 between described bolt block 1 and the bolt head 3;
In the present embodiment, described bolt block 1 cross section is square structure; Increase soundness from warping force and withdrawal force aspect, and the possibility that plastics crack around reducing.
In the present embodiment, described bolt block 1 edges and corners are provided be used to the R angle 2 that seamlessly transits; Make cambered surface more even level and smooth, more easily prevent place or drawing breaking, because bolt block 1 is embedded in the spoiler, therefore when bolt strained, be not easy to damage spoiler.
In the present embodiment, described annular stop boss 4 cross sections are isosceles trapezoid; Because bolt head 3 is used in conjunction with the standard piece hexagon nut with flange, the spoiler body is fixed on the backdoor hinge stiffening plate, therefore boss 4 had both played spacing effect, can combine closely with nut again and be fixed in the backdoor hinge stiffening plate, increase the pretightening force of bolt, thereby strengthen the fixing stability of bolt.
In the present embodiment, described bolt is the M6 bolt; Torsion is moderate.
In the present embodiment, utilize the stiffening plate of backdoor inner plate to stretch out a platform, as with the installation contact plane of spoiler, affected by sheet-metal formed, this extended height is limited, and the mounting plane of spoiler is affected by blow moulding process, and contact plane is installed also narrow limitation, finally causes differing approximately 19mm between two mounting planes.When the pre-buried special bolt of design, design a transition platform, namely guaranteed to install the area and intensity of contact plane, can not affect again the function of bolt itself.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
