Abstract
The utility model discloses gps antenna in a kind of jamproof car, described upper cover is arranged on above base, is provided with matrix shielding box in described base, and described ceramic antenna is placed on shielding box; Be provided with swivel base above described base, be provided with bottom described ceramic antenna for fixing support, described support installing is on swivel base; Described side face is provided with vertical knob, is provided with horizontal knob bottom described swivel base, and described vertical knob and horizontal knob stretch out from base; Cover on described and be provided with sticking structure.The beneficial effects of the utility model, adopt signal that shielding box can stop that other equipment send in car on the impact of gps antenna, reduce signal disturbing; Upper cover is provided with sticking structure simultaneously, can be arranged on the optional position of vehicle window easily; Box body arranged outside has vertical knob and horizontal knob simultaneously, may be used for the angle of finely tuning ceramic antenna, makes acknowledge(ment) signal effective area larger, thus significantly improves gps signal intensity.
Description
Technical field
The utility model relates to auto parts machinery field, is specifically related to gps antenna in a kind of jamproof car.
Background technology
GPS exactly by accepting satellite-signal, the terminal positioning or navigate.And acknowledge(ment) signal just must use antenna.Gps satellite signal is divided into L1 and L2, and frequency is respectively 1575.42MHZ and 1228MHZ, and wherein L1 is open civil signal, and signal is Circular Polarisation.Signal strength signal intensity is about-166DBM, belongs to more weak signal.These features determine and will prepare special antenna for the acceptance of gps signal.
GPS can be divided into: polarization mode, gps antenna is divided into perpendicular polarization and Circular Polarisation; From modes of emplacement, gps antenna is divided into built-in aerial and external antenna; Divide again active and passive from power supply aspect.
Affect mainly the following aspects of gps antenna performance: potsherd, the quality of ceramic powders and sintering process directly affect its performance; Silver layer, ceramic antenna surface silver layer can affect antenna resonance frequency, and frequency accurately drops on 1575.42MHz; Feedback point, ceramic antenna is collected resonance signal by feedback point and is sent to rear end; Amplifying circuit, the PCB shape of carrying ceramic antenna and area.Gps antenna has four important parameters: gain, standing wave, noise factor, axial ratio.Wherein lay special stress on axial ratio, it weighs complete machine to the important indicator of the signal gain otherness of different directions.Because satellite is randomly dispersed on hemisphere sky, so ensure that antenna all has close susceptibility to be very important in all directions.Axial ratio is subject to the impacts such as antenna performance, surface structure, complete machine internal circuit and EMI.
Existing is exactly be placed in car in addition, is placed in car and has two kinds of mounting meanss: one is by concealed installation in GPS external antenna car, is contained in inside automobile center console.Two is filled by gps antenna Che Neiming, to be placed on the right side of front windshield below A post above console.These two kinds of modes have drawback, and gps antenna is placed on signal below console by the former will penetrate the interference that console also has the electronic product inside console, and the signal received is very poor.Gps antenna is placed on console by the latter, and signal makes moderate progress, but if the signal that windshield metal rupture pressure disc gps antenna receives also can be very weak.In existing car, gps antenna disturbing factor is more, dtr signal.
Utility model content
For the problems referred to above, the utility model aim to provide a kind of be easy to install and the adjustable ceramic antenna angle in antijamming capability chamber obtain better signal car in gps antenna.
For realizing this technical purpose, scheme of the present utility model is: gps antenna in a kind of jamproof car, comprises ceramic antenna, base, upper cover, and described upper cover is arranged on above base, be provided with matrix shielding box in described base, described ceramic antenna is placed on shielding box;
Be provided with swivel base above described base, be provided with bottom described ceramic antenna for fixing support, described support installing is on swivel base; Described side face is provided with vertical knob, is provided with horizontal knob bottom described swivel base, and described vertical knob and horizontal knob stretch out from base; Cover on described and be provided with sticking structure.
As preferably, below described ceramic antenna, be provided with the resilient coating of annular.
As preferably, described sticking structure can be 3M sticker or sucker.
As preferably, described support is three-legged structure.
As preferably, described base side is provided with the notch for putting line.
The beneficial effects of the utility model, adopt signal that shielding box can stop that other equipment send in car on the impact of gps antenna, reduce signal disturbing; Upper cover is provided with sticking structure simultaneously, can be arranged on the optional position of vehicle window easily; Box body arranged outside has vertical knob and horizontal knob simultaneously, may be used for the angle of finely tuning ceramic antenna, makes acknowledge(ment) signal effective area larger, thus significantly improves gps signal intensity.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of another specific embodiment of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, specific embodiment described in the utility model is gps antenna in a kind of jamproof car, comprises ceramic antenna 2, base 1, upper cover 3, and described upper cover 3 is arranged on above base 1, be provided with matrix shielding box 5 in described base 1, described ceramic antenna 2 is placed on shielding box 5; Be provided with swivel base 9 above described base 1, be provided with bottom described ceramic antenna 2 for fixing support 8, described support 8 is arranged on swivel base 9; Described support 8 side is provided with vertical knob 6, is provided with horizontal knob 7 bottom described swivel base 9, and described vertical knob 6 and horizontal knob 7 stretch out from base 1; Described upper cover 3 is provided with sticking structure 4.Can the design of adjusting angle owing to adopting, after fixation, easily there is weak vibrations in ceramic antenna, is provided with the resilient coating 11 of annular below described ceramic antenna 2, and described resilient coating effectively can absorb impulsive force to be reduced and rock.Fixing for the ease of gps antenna, described sticking structure 4 can be 3M sticker or sucker; If for one-time fixing, better by 3M sticker effect, if often need mobile, adopt sucker effect better.In order to improve the stability of ceramic antenna, described support 8 is three-legged structure.Draw from base side for the ease of holding wire, described base 1 side is provided with the notch 10 for putting line.
During use, by sticking structure and car glass gluing, then holding wire is connected with vehicle-mounted navigator; On the place of spaciousness, regulate vertical knob, ceramic antenna angle is rotated, makes ceramic antenna be in the stronger position of signal, then finely tune horizontal knob, ceramic antenna angle is rotated, finally make ceramic antenna be in optimum signal receiving position; Last fixed vertical knob and horizontal knob, make it not rotate.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection range that all should be included in technical solutions of the utility model.
