Abstract
The utility model discloses a vehicle radio-frequency electronic signal receiving device including a shark-fin-shaped shell pedestal arranged on the top of an automobile and a shark-fin-shaped shell connected to the shark-fin-shaped shell pedestal. A groove used for receiving an antenna is arranged in the center of the shark-fin-shaped shell pedestal. The length of the antenna is a quarter of a wavelength. The antenna adopts copper foils and is manufactured through adopting FPC (Flexible Printed Circuit) silk printing. The antenna is connected with an entertainment host. Compared with the prior art, the sensitivity value, the efficiency value and the frequency width of the antenna are improved substantially, the signal receiving strength of a radio is improved, the reception becomes stable and the reception effect is enhanced according to the utility model.
Description
Technical field
The utility model relates to a kind of vehicle-mounted radio frequency electric signal receiving device.
Background technology
What have utilization on the market now is pure passive type antenna, simple by a spring, an iron receives body as antenna and receives the broadcast receiver radiofrequency signal, do not design the reception body of suitable this frequency range fully according to the frequency range of broadcast receiver frequency, can not well receive the frequency that is fit to the broadcast receiver frequency range like this, cause broadcast receiver effect extreme difference, the broadcast receiver noise can't satisfy car owner's the demand of listening to greatly.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of vehicle-mounted radio frequency electric signal receiving device is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of vehicle-mounted radio frequency electric signal receiving device, comprise the shark fins outer casing base that is arranged at automobile top and the shark fins shell that is connected in described shark fins outer casing base, be provided with the groove of a placement antenna in the middle of the described shark fins outer casing base, described antenna length is 1/4 wavelength, use Copper Foil and adopt FPC silk-screen or flexible PCB to make, described antenna links to each other with the amusement main frame.
The beneficial effects of the utility model are:
The utility model compared with prior art improves sensitivity value and efficiency value and the frequency range of antenna greatly, can make strength of radio received signal better, and reception is more stable, and audibility is more clear.Use the vehicle-mounted radio frequency electric signal receiving device of this shark fins moulding both can avoid the vehicle antenna that when short spaces such as turnover garage, fractures to cause broadcast receiver to use, replace former car handle antenna and make auto radio still can guarantee normally to listen to, can also make the car body cleanliness beautiful more attractive in appearance.Overcome prior art and can't well design and match the reception body that just in time is fit to receive frequency range, can't avoid the big problem of broadcast receiver noise.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 shark fins outer casing base structural representation;
Fig. 2 shark fins shell mechanism schematic diagram;
Fig. 3 antenna structure view.
Number in the figure explanation: 1, shark fins outer casing base, 101, groove, 2, the shark fins shell, 3, antenna.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to shown in Figure 1, a kind of vehicle-mounted radio frequency electric signal receiving device, comprise the shark fins outer casing base 1 that is arranged at automobile top and the shark fins shell 2 that is connected in described shark fins outer casing base 1, be provided with the groove 101 of a placement antenna 3 in the middle of the described shark fins outer casing base 1, described antenna 3 length are 1/4 wavelength, use Copper Foil and adopt FPC silk-screen or flexible PCB to make, described antenna 3 links to each other with the amusement main frame.
By electric field and magnetic field radiation principle and Maxwell equation principle, in design process, antenna 3 Design of length are become according to 1/4 λ wavelength, use Copper Foil, adopt the mode of FPC silk-screen or flexible PCB to present, can make the reception signal strength signal intensity better like this, reception is more stable, improves sensitivity value and efficiency value and the frequency range of antenna 3 greatly.Antenna 3 is placed in the shark fins outer casing base 1, and shark fins outer casing base 1 directly overlays the top antenna base, uses 3M adhesive tape and roof bonding fixing.Antenna 3 is connected transmission by one section copper cash with the top antenna base after receiving the radio reception signal, radio receiver signal is transferred to the amusement main frame, thereby broadcast receiver can normally be listened to.Use the vehicle-mounted radio frequency electric signal receiving device of this shark fins moulding both can avoid the vehicle antenna that when short spaces such as turnover garage, fractures to cause broadcast receiver to use, replace former car handle antenna and make auto radio still can guarantee normally to listen to, can also make the car body cleanliness beautiful more attractive in appearance.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
