Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a vehicle exterior casing provided by an embodiment of the invention, and referring to fig. 1, the vehicle includes a vehicle exterior casing, the vehicle exterior casing includes at least a part of a metal casing 1, the metal casing 1 is formed with a V2X antenna, the vehicle further includes a V2X device, and the V2X device is electrically connected with the V2X antenna.
Specifically, as shown in fig. 1, the vehicle may be, for example, an automobile, a truck, or the like, and the vehicle may include a vehicle body and a vehicle exterior cover that covers the vehicle body, so that a receiving space for carrying passengers or cargo is formed between the vehicle exterior cover and the vehicle body; the V2X antenna 11 may only have a function of receiving signals, or may be a bidirectional antenna having functions of receiving and transmitting signals, and the V2X device is configured to process signals received by the V2X antenna, so as to control the vehicle to perform corresponding operations, such as avoiding obstacles; the V2X device may also send signals out through the V2X antenna to complete communication between the vehicle and other networked bodies (e.g., vehicles); since the vehicle housing usually contains a large amount of metal materials, and since no shielding metal is generally present outside the vehicle housing, the present embodiment may make a part of the metal part in the vehicle housing into the V2X antenna 11, that is, the V2X antenna 11 is integrally formed when the vehicle housing is processed, so that the V2X device may be disposed at a short distance from the V2X antenna 11; on one hand, the V2X antenna does not need to be arranged on the roof outside the vehicle shell, so that holes do not need to be drilled on the vehicle shell, and in addition, a very long cable line does not need to be arranged, so that the loss of signals on the cable line is very small, the communication distance can be greatly improved, and the application of the V2X technology is facilitated; on the other hand, since the V2X antenna does not need to be arranged inside the vehicle shell, the vehicle shell does not interfere with the radio frequency signal of V2X communication, and therefore the problem of poor communication can be avoided.
According to the technical scheme, the adopted vehicle comprises a vehicle outer shell, the vehicle outer shell comprises at least a part of a metal shell, the metal shell is provided with a V2X antenna, the vehicle further comprises a V2X device, and the V2X device is electrically connected with the V2X antenna. The V2X antenna is directly manufactured by the metal part of the vehicle shell, the V2X antenna does not need to be arranged on the roof or in the vehicle, the distance between the V2X antenna and the V2X equipment can be set to be closer, and the V2X antenna is not shielded by metal materials, so that the problems of overlong attenuation of a coaxial cable line and shielding of signals in the vehicle are solved, normal communication of the V2X is ensured, and the assembly of the scheme has a simple and effective effect.
Optionally, with continued reference to fig. 1, the V2X antenna 11 is an inverted-F antenna (IFA), the metal housing 1 includes an inverted-F antenna and a main metal 12, the inverted-F antenna includes an antenna radiator 111, a shorting bar 112, and an antenna feed 113, wherein the antenna radiator 111 is connected to the main metal 12 through the shorting bar 112, and the V2X device is electrically connected to the shorting bar 112 and the antenna feed 113 through a short coaxial cable.
Specifically, the inverted-F antenna has the advantages of wider tunable resonant frequency, better resonance performance and the like, and the V2X antenna is set as the inverted-F antenna, so that the V2X antenna can be ensured to have a wider tunable resonant frequency range and excellent radiation performance. As shown in fig. 1, the antenna radiator 11 includes a portion (set to S) between the shorting bar 112 and the antenna feed point 113 and another portion (set to L), the shorting bar 112 is electrically connected to the main metal 12, and the main metal 12 provides a ground signal for the shorting bar 112, that is, the length of the shorting bar 112 is set to H, where L has a large influence on the resonant frequency and the input impedance of the antenna, when the length of L increases, the resonant frequency of the V2X antenna 11 decreases, and the input impedance decreases, and conversely, when the length of L decreases, the resonant frequency of the antenna increases, and the input impedance increases; the general rule of H is that when H is increased, the resonant frequency is reduced, the input impedance is increased, and when H is decreased, the resonant frequency is increased, and the input impedance is decreased; the general rule of S is that when S increases, the resonant frequency increases and the input impedance decreases; when S decreases, the resonance frequency decreases and the input impedance increases. The V2X device is electrically connected to the shorting bar 112 and the antenna feed point 113 of the inverted-F antenna by coaxial cable lines to feed the antenna signal to the inverted-F antenna. Of course, in other embodiments, the V2X antenna may be another type of antenna, such as another type of monopole antenna. In the embodiment, the short-circuit rod of the inverted-F antenna is electrically connected with the main metal 12, and since the shell of the vehicle body is equivalent to be grounded, the inverted-F antenna is equivalent to be perpendicular to the ground by the inverted-F antenna, the polarization mode of the inverted-F antenna is vertical polarization, and the direction of the inverted-F antenna is an omnidirectional antenna; in other words, the inverted-F antenna of the present embodiment is arranged in a manner such that the capability of the inverted-F antenna for radiating and receiving signals in each direction is substantially the same, and no matter which direction the inverted-F antenna faces, a better communication effect can be achieved, which is more beneficial to integrating the V2X antenna on the vehicle body shells under different conditions, and improving the compatibility of the vehicle-mounted V2X antenna.
Alternatively, with continued reference to fig. 1, the distance (d1) between the antenna radiator 11 and the body metal 12 in the direction Y perpendicular to the extending direction X of the antenna radiator 111 is greater than 1.4 mm; the distance (d2 and d3) between the antenna radiator 111 and the body metal 12 in the extending direction X of the antenna radiator 11 is greater than 3 mm.
Specifically, if the distances between d1, d2 and d3 are too small, the efficiency of the V2X antenna will be reduced sharply, and the effectiveness of V2X communication cannot be guaranteed; therefore, the present embodiment can ensure high communication efficiency of the V2X antenna by setting d1 to be greater than 1.4 mm and d2 and d3 to be greater than 3 mm.
Alternatively, in order to further improve the communication efficiency of the V2X antenna, the thickness of the antenna radiator 111 may be set to be less than 1.5 mm. It should be noted that the length of the antenna radiator, i.e., the length of the L portion, may be determined according to the preset IFA antenna, and may be, for example, about 25 mm (i.e., 1/2 wavelength of V2X communication frequency 5.9G), so that the tunable resonant frequency range of the V2X antenna may be relatively large.
Optionally, a substrate material is filled between the antenna radiator 111 and the bulk metal 12, and a dielectric constant of the substrate material is less than 2.55.
Specifically, the substrate material can provide support for the V2X antenna 11, avoid the V2X antenna 11 from being damaged due to collision and the like, and can play a role in isolation; the substrate material may be a material with a low loss tangent, a material with a mechanical property that is easy to process, and a material with a good temperature stability, and preferably, the substrate material may be, for example, an ABS plastic (Acrylonitrile Butadiene Styrene plastic), which has a dielectric constant of about 2.4 and a high stability in temperature or frequency change, so as to ensure a good isolation effect on the inverted-F antenna.
Optionally, fig. 2 is a schematic structural diagram of another vehicle exterior shell according to an embodiment of the present invention, in this embodiment, the vehicle further includes an aperture tuning circuit 13, the aperture tuning circuit 13 is electrically connected to the antenna radiator 111 and the main metal 12, and the aperture tuning circuit 13 is configured to adjust a resonant frequency of the inverted-F antenna 11.
Specifically, for different vehicles, because the electromagnetic environments of the vehicles cannot be completely the same, for example, the metal materials used for the vehicle housings of the different vehicles may be different, and the metal parts of the vehicle housings may also be different, the V2X antennas with the same size are manufactured, and the resonant frequencies thereof may also be different, so that the communication efficiency of the different vehicles is greatly different, and the application range of the V2X antenna manufactured by using the vehicle housing is narrow; in this embodiment, by providing the aperture tuning circuit 13, the aperture tuning circuit 13 can adjust the resonant frequency of the V2X antenna 11, and after the vehicle is manufactured, the resonant frequency of the V2X antenna of different vehicles can be adjusted to the frequency required by V2X communication by adjusting the parameters of the aperture tuning circuit 13, thereby greatly improving the application range of directly manufacturing the V2X antenna by using the vehicle housing.
Exemplarily, fig. 3 is a schematic circuit structure diagram of an aperture tuning circuit according to an embodiment of the present invention, and referring to fig. 3, the aperture tuning circuit 13 includes: a voltage division capacitor C0, a tuning capacitor C1 and a tuning inductor L0; the first end of the voltage-dividing capacitor C0 is electrically connected with the antenna radiator, and the second end of the voltage-dividing capacitor C0 is electrically connected with the first end of the tuning capacitor C1; the second end of the tuning capacitor C1 is electrically connected with the body metal; a first end of the tuning inductor L1 is electrically connected with a second end of the voltage-dividing capacitor C0, and a second end of the tuning inductor L1 is electrically connected with the bulk metal; at least one of the voltage dividing capacitor C0, the tuning capacitor C1 and the tuning inductor L1 has adjustable parameters.
Specifically, in this embodiment, the voltage-dividing capacitor C0, the tuning capacitor C1, and the tuning inductor L1 form an LC oscillating circuit, and the resonant frequency of the oscillating circuit can be adjusted by adjusting one of the parameters, so as to adjust the resonant frequency and the return loss of the inverted F antenna. In the embodiment, the aperture tuning circuit can be formed by utilizing two capacitors and one inductor, and the circuit is simple in structure and easy to realize. Preferably, the voltage dividing capacitor C0, the tuning capacitor C1, and the tuning inductor L1 may be all adjustable, so that the degree of freedom of adjustment of the resonant frequency of the inverted F antenna may be improved.
Optionally, the connection point of the antenna radiator 11 and the aperture tuning circuit 13 is configured as a moveable connection point.
Specifically, the connection point of the antenna radiator 11 and the aperture tuning circuit 13 is located on the side of the antenna feed point 113 away from the shorting bar 112, the connection point affects the change amplitude of the frequency, and the tuning range is larger as the connection point is farther away from the antenna feed point 113, so that the degree of freedom of the resonant frequency adjustment of the inverted-F antenna can be further improved by setting the connection point to be a movable connection point in the present embodiment.
Exemplarily, fig. 4 is a return loss graph of the V2X antenna under different parameters of the aperture tuning circuit, as shown in fig. 4, where a solid line is an original waveform of the return loss, and a dotted line is a waveform obtained by adjusting a value of the tuning capacitor C1 when the voltage dividing capacitor C0 is unchanged and the tuning inductor L1 is unchanged, as can be seen from fig. 4, by adjusting the parameters of the aperture tuning circuit, the resonant frequency of the V2X antenna can be adjusted.
In summary, if the shape and the layout of the antenna of the IFA are prepared in advance according to the frequency band 5905MHz-5925MHz of V2X, the required result can be obtained by adjusting the position of the connection point or changing the C0, C1 or L0 value of the aperture tuning circuit.
Exemplarily, the V2X antenna 11 is made of a metal part of a vehicle rear view mirror or of a metal part of a door handle on the left and right of a front door of a vehicle; the V2X device is disposed in the front door of a vehicle.
Specifically, the arrangement positions of the V2X antenna 11 and the V2X device include three principles, one is that the V2X device is convenient to arrange, and there are enough antenna radiation spaces before and after the position for manufacturing the V2X antenna nearby without signal-shielding metal objects; secondly, the material is metal or can be made of metal; thirdly, since the ground requiring the metal on the vehicle body as the antenna may interfere with other electronic devices and affect the efficiency of the V2X antenna, the ground may be located at a position far from the other electronic devices. The housings of the left and right rearview mirrors of the vehicle can be made of metal, and the housings of the rearview mirrors are relatively hollow and are not shielded by metal materials, so that the housings of the rearview mirrors of the vehicle can be made into V2X antennae, and the door handles of the vehicle can also meet the two conditions, so that the housings can be used for making V2X antennae; in addition, in order to reduce the length of the coaxial cable used between the V2X antenna and the V2X device, the V2X device may be disposed in the front left and right doors of the vehicle, that is, the front left door or the front door, when the V2X antenna is fabricated on the front left mirror or the front left door handle, the V2X device is disposed in the front left door, and when the V2X antenna is fabricated on the front right mirror or the front right door handle, the V2X device is disposed in the front right door. Of course, in other embodiments, the V2X antenna and the V2X device may be fabricated in other locations in the vehicle. When the V2X antenna includes a plurality of V2X devices may be disposed at a short distance from the V2X antenna for the transceiving function, and at a long distance from the V2X antenna having only the receiving function.
It is to be noted that the foregoing is only illustrative of the preferred embodiments of the present invention and the technical principles employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
