Abstract
The utility model discloses a kind of shark fins antenna fixing structure, comprises metab, the first set bolt; Described first set bolt is threaded with described metab, between the first set bolt and metab, be provided with metal spring piece; Described metal spring piece, comprises the substrate be set on the first set bolt, and described substrate at least side sidewall connection one punctures plate; The described plate one end that punctures is connected with substrate, and the other end is provided with sharp protrusion.Utilize the utility model shark fins antenna after fixation, metal spring piece puncture the ground connection good with vehicle body of spraying paint that plate punctures vehicle body ceiling, avoid because imperfect earth causes radio reception noise problem; In addition, the utility model also uses flexible fastening mode, even if vehicle body ceiling is with radian, shark fins also can well and vehicle body ceiling fix.
Description
Technical field
The utility model relates to shark fins antenna, especially shark fins antenna fixing structure.
Background technology
Along with the development of automotive electronic technology, the integrated increasing wireless communication function of vehicle electronic device, as radio reception, navigation, 3G communication, mobile digital TV etc., and shark fin type car antenna can the various antenna receiving function such as integrated radio reception, navigation, 3G communication, for mobile unit provides aerial signal.
As shown in Figure 1, existing shark fins antenna structure comprises: shark fins shell 1, signal processing circuit board 2 is provided with in shark fins shell 1, signal processing circuit board 2 is fixed on metab 3, shark fins shell 1 and metab 3 are tightly connected, and metab 3 is fixed on vehicle body ceiling by set bolt 4; But, in actual entrucking process, spraying paint of vehicle body ceiling surface itself is insulation, tighten fixing by means of only set bolt 4 and vehicle body ceiling, cannot ensure that the set bolt 4 of antenna directly can contact with vehicle body ceiling metal, thus cause shark fins antenna not have and metal body ground connection, cause antenna radio reception noise to increase; Meanwhile, vehicle body ceiling surface has radian, is not plane completely, once automobile produces huge shake under steam, then set bolt is likely because can slosh and cannot being adjacent to the arcuate surfaces of vehicle body ceiling; Therefore, there is hidden danger in the fixed structure of existing shark fins antenna, not only easily affects the radio reception effect of mobile unit, and, fixing in some cases and unreliable.
Utility model content
The purpose of this utility model is to provide a kind of can guarantee to carry out good ground connection with vehicle body metal, avoids because of imperfect earth, causes radio reception noise; Can be good at and good the fixing of vehicle body ceiling with radian, avoid in vehicle traveling process, violent vibration causes shark fins antenna to fix bad shark fins antenna fixing structure simultaneously.
For achieving the above object, the shark fins antenna fixing structure of the utility model design, comprises metab, it is characterized in that: also comprise the first set bolt, described first set bolt is threaded with described metab, between the first set bolt and metab, be provided with metal spring piece; Described metal spring piece, comprises the substrate be set on the first set bolt, and described substrate at least side sidewall connection one punctures plate; The described plate one end that punctures is connected with substrate, and the other end is provided with sharp protrusion.
Preferably, described metab is also threaded the second set bolt.Fixing for assistant metal base and vehicle body ceiling, and can prevent from causing rotation because antenna volume is excessive.
As another preferred version, described in puncture plate one end and be arranged with two described sharp protrusion, be provided with breach between two described sharp protrusion.
Preferably, the sidewall that described substrate two is relative is equipped with and punctures plate.
Further preferably, puncture between plate and substrate described in and be provided with obtuse angle angle.Like this, opening when tightening is convenient to.
The beneficial effects of the utility model are: utilize the utility model shark fins antenna after fixation, metal spring piece puncture the ground connection good with vehicle body of spraying paint that plate punctures vehicle body ceiling, avoid because imperfect earth causes radio reception noise problem; In addition, the utility model also uses flexible fastening mode, even if vehicle body ceiling is with radian, shark fins also can well and vehicle body ceiling fix.
Accompanying drawing explanation
Fig. 1 is existing shark fins antenna fixing structure exploded perspective view;
Fig. 2 is exploded perspective view of the present utility model;
Fig. 3 is schematic front view of the present utility model;
Fig. 4 is the cross-sectional schematic of Fig. 3;
In figure: shark fins shell 1, signal processing circuit board 2, base 3, set bolt 4, first set bolt 5, cable 6, metal spring piece 7, vehicle body ceiling 8, second set bolt 9;
Wherein: substrate 7.1, puncture plate 7.2, sharp protrusion 7.3, breach 7.4.
Embodiment
As shown in Figure 1, be the shark fins antenna structure of prior art, set forth its structure in the introduction, again do not repeated.
As shown in Figure 2, the utility model design shark fins antenna fixing structure, comprise metab 3, the first set bolt 5; Metab 3 is fixed a signal processing circuit board 2, signal processing circuit board 2 is communicated by the cable 6 passed bottom metab 3; Described first set bolt 5 is threaded with described metab 3, between the first set bolt 5 and metab 3, be provided with metal spring piece 7; Described metab 3 is also threaded the second set bolt 9, fixing for assistant metal base 3 and vehicle body ceiling 8, and can prevent from causing rotation because antenna volume is excessive.
As shown in Figures 2 to 4, described metal spring piece 7, comprises the substrate 7.1 be set on the first set bolt 5, and described substrate 7.1 at least side sidewall connection one punctures plate 7.2, and in the present embodiment, the sidewall that described substrate 7.1 liang is relative is equipped with and punctures plate 7.2; Described plate 7.2 one end that punctures is connected with substrate 7.1, and the other end is provided with sharp protrusion 7.3.
As shown in Figure 3, preferably, puncture plate 7.2 one end described in be arranged with between two described sharp protrusion, 7.3, two described sharp protrusion 7.3 and to be provided with breach 7.4.
Preferably, described in puncture between plate 7.2 and substrate 7.1 and be provided with obtuse angle angle, like this, be convenient to opening when tightening.
Metal spring piece 3 adopts the stainless steel material with favorable elasticity, tighten in the process of the first set bolt 5, metal spring piece 7 can be deformed into open configuration due to the power of locking being subject to the first set bolt 5, the sharp protrusion 7.3 punctured on plate 7.2 of metal spring piece 7 punctures spraying paint of vehicle body ceiling 8, and thrust vehicle body sheet metal, form good earthing effect; Simultaneously four sharp protrusion 7.3 are engaged with vehicle body ceiling, and form good stationary state, no matter whether vehicle body ceiling with radian, metab also can well and vehicle body ceiling 8 fixing.
