Description
Technical field
The utility model relates to auto-parts field, particularly relates to a kind of automobile tail fin of high strength.
Background technology
Automobile tail fin is as a kind of auto-parts, and its Main Function is the lift in order to reduce vehicle tail.In the process of moving, the lift as the tailstock is larger than the lift of headstock, then very easily cause turning to of automobile too much, trailing wheel earth-grasping force reduces, and high stability is poor.In addition, people find in use, and when the rainy day travels, splash by each surface gathered water of wheel water dumping and affect, automobile tail is usually stained with rainwater and mud, adds that empennage blocks rainwater washing away the tailstock, brings great impact to the overall appearance of automobile.Also there is structure shakiness in existing automobile tail fin, holds caducous problem.
Given this, be necessary that a kind of new automobile tail fin of design solves above-mentioned technical matters.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is the automobile tail fin providing a kind of high strength, its Stability Analysis of Structures, difficult drop-off; And overall volume is little, do not affect rainwater washing away the tailstock.
For achieving the above object, the utility model adopts following technical scheme:
An automobile tail fin for high strength, comprises empennage body and housing, and arcuately, the outside of empennage body is arranged at intervals with multiple projection to empennage body along its length, and the cross-sectional plane of empennage body is trapezoidal, and this empennage body reduces from middle part gradually to two ends; The lateral wall of described projection offers support slot; Described housing comprises top board and side plate, top board and side plate V-shaped, case inside is provided with multiple holding section of matching with support slot, and the top board of housing and side plate are individually fixed in upper surface and the lower surface of empennage body by ultrasonic welding technique, and location is planted with in support slot in described holding section.
Further, the upper surface of described empennage body and lower surface are equipped with welding raised line.
Further, the angle between the top board of the angle between the upper surface of described empennage body and lower surface and housing and side plate is consistent.
Further, described case inside is provided with multiple spacer along its length, and spacer is connected to the front surface of empennage body.
Further, the cross-sectional plane of this automobile tail fin is triangle.
Compared to prior art, the utility model brings following beneficial effect:
One, by automobile tail fin by empennage body and housing two parts by together with ultrasonic welding, without the need to using screw and glue laminating, reaching the advantage that intensity is high after welding, and saving manpower;
Two, by arranging support slot and holding section between empennage body and housing, being not only conducive to location therebetween, realizing quick assembling, fixing, and the intensity of empennage can be strengthened further;
Three, whole tail structure is reasonable in design, volume-diminished, does not affect rainwater washing away the tailstock, does not affect the appearance looks elegant of automobile simultaneously.

Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Refer to Fig. 1 to Fig. 4, the utility model discloses a kind of automobile tail fin of high strength, comprise empennage body 1 and housing 2, empennage body 1 and housing 2 obtain by having thermoplastic plastic material, empennage body 1 arcuately, the outside of empennage body 1 is arranged at intervals with multiple projection 11 along its length, and the cross-sectional plane of empennage body 1 is trapezoidal, and this empennage body 1 reduces from middle part gradually to two ends; Described housing 2 has the profile matched with empennage body 1, comprises top board 21 and side plate 22, top board 21 and side plate 22 V-shaped; The lateral wall of described projection 11 offers support slot 111, multiple holding section (as shown in Figures 3 and 4) of matching with support slot 111 is provided with inside described housing 2, specifically in the present embodiment, described support slot 111 is bar shaped horizontal slot, described holding section is specially the retaining sheet 23 of level, retaining sheet 23 is planted with in support slot 111, thus realize the quick position of empennage body 1 and housing 2, be convenient to the carrying out of follow-up fusion joining process, further, this design also helps the anchoring strength strengthened between empennage body 1 and housing 2.
The top board 21 of housing 2 and side plate 22 are individually fixed in upper surface and the lower surface of empennage body 1 by ultrasonic welding technique, during concrete welding, first housing 2 be installed in the outside face of empennage body 1 and mutually extrude, the upper surface of the inside face of housing 2 and empennage body 1 and lower surface are compressed mutually, ul-trasonic irradiation is when thermoplastic plastic contact surface, produce the high-frequency vibration of several ten thousand times per second, the energy of vibration makes contact surface melt rapidly, after adding certain pressure, make it be fused into one, this fixed form is without the need to using screw or glue laminating, save the troublesome operation manually the two be fixed, and this kind of fixed form has high mechanical strength, meet the shockproof requirements as auto-parts completely.
As improving further, upper surface and the lower surface of described empennage body 1 are equipped with welding raised line, be specially the tiny fin 12 (as shown in Figures 1 and 2) protruding from empennage body 1 upper surface and lower surface, during welding, the inside face of housing 2 is actually tiny fin 12 welding mutually with these, this design empennage body 1 and housing 2 can be made to combine more evenly, firm, avoid the problem due to the upper and lower surface of empennage body 1 and the uneven welding weak effect caused of housing 2 internal surface gaps; In addition, tiny fin 12 can be set to strip shape, also can be arc or other shapes.
The holding section of above-mentioned support slot 111 and correspondence is only a kind of specific embodiment, understandable, and support slot 111 can also be other shapes, such as circular hole or square hole, accordingly, described holding section is then for holding cylinder or holding square column, and any other structure mutually can planting location all can use.
Be worth mentioning, angle between the top board 21 of the angle between the upper surface of described empennage body 1 and lower surface and housing 2 and side plate 22 is consistent, after having assembled, the cross-sectional plane of the automobile tail fin be made up of this empennage body 1 and housing 2 is triangle, when being assemblied on automobile, the end of this automobile tail fin is upturned, according to fluid mechanics principle, the pressure that the gas flowed can give automobile tail one downward at the automobile tail fin through this shape, thus it is more stable to guarantee that running car obtains.
Further, be provided with multiple spacer 24 along its length inside described housing 2, spacer 24 is connected to the front surface of empennage body 1, and this setting can further improve the assembling speed of empennage body 1 and housing 2.
Compared to prior art, the utility model brings following beneficial effect:
One, by automobile tail fin by empennage body 1 and housing 2 two parts by together with ultrasonic welding, without the need to using screw and glue laminating, reaching the advantage that intensity is high after welding, and saving manpower;
Two, by arranging support slot 111 and holding section between empennage body 1 and housing 2, being not only conducive to location therebetween, realizing quick assembling, fixing, and the intensity of automobile tail fin can be strengthened further;
Three, whole tail structure is reasonable in design, volume-diminished, does not affect rainwater washing away the tailstock, does not affect the appearance looks elegant of automobile simultaneously.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
