From the above data, the bluetooth frequency range is very close to the 4G/5G frequency, and the antenna multiplexing can be realized, i.e. the bluetooth module and the 4G/5G module share one wire.
Referring to fig. 2 and 3, the solution shown in fig. 1 is modified in order to reduce costs. Specifically, the bluetooth system in this embodiment employs a new multiplexed antenna assembly 100. Multiplexing antenna assembly 100 is connected to the host computer, and the host computer is integrated with bluetooth module and 4G/5G module, and wherein, 4G module generally is provided with two antennas, and 5G module generally is provided with more than 4 antennas. The multiplexing antenna assembly 100 includes at least one bluetooth antenna 1 connected to a bluetooth module, a plurality of 4G/5G antennas 2 connected to a 4G/5G module, and a multiplexing switch 3. The bluetooth antenna 1 is used for receiving and transmitting bluetooth signals. The 4G/5G antenna 2 is used for receiving and transmitting 4G/5G signals. Wherein, one Bluetooth antenna 1 in at least one Bluetooth antenna 1 is connected with one 4G/5G antenna 2 in a plurality of 4G/5G antennas 2 to form a multiplexing antenna. Specifically, in this embodiment, the antenna portion 11, the connector 12, and the rf line 13 of one bluetooth antenna 1 are eliminated, only the PCB trace 14 located in the host remains, and then the PCB trace 14 is connected to the rf line 13 on one 4G/5G antenna 2, so that after the 4G/5G antenna 2 is connected to the host through the connector 12 and the rf line 13, the two separate PCB traces 14 are respectively connected to the 4G/5G module and the bluetooth module in the host, thereby implementing the multiplexing function. In order to control the multiplexing antenna, the multiplexing antenna assembly is further provided with a multiplexing switch 3, the multiplexing switch 3 is disposed at the multiplexing antenna, and specifically, the multiplexing switch 3 is connected to two PCB traces 14 of the multiplexing antenna and is used for communicating one of the two PCB traces 14. The multiplexing switch 3 is configured to turn on the multiplexing antenna and the Bluetooth module or turn on the multiplexing antenna and the 4G/5G module according to the received control signal. Specifically, when the bluetooth module is used, the multiplexing switch 3 controls the multiplexing antenna to be connected with the bluetooth module according to a control signal sent by the host. When the 4G/5G module is used, the multiplexing switch 3 controls the multiplexing antenna to be conducted with the 4G/5G module according to a control signal sent by the host. When the two signals are sent out simultaneously, the multiplexing antenna and the Bluetooth module are preferentially conducted. By adopting the antenna assembly, the antenna part 11, the connector 12 and the radio frequency line 13 of one Bluetooth antenna 1 can be reduced, and the cost of the high-frequency relay is lower, so that the cost can be effectively reduced, and the Bluetooth radio frequency performance is met.
The multiplexing antenna assembly 100 in the above embodiment is applied to a vehicle networking system of a vehicle, and specifically, the multiplexing antenna assembly 100 may be mounted on the top of the vehicle (shark fin or flat plate structure), and may be disposed on the central axis of the vehicle, where the signal strength is strongest and the areas are symmetrical. It should be understood that the top here refers not only to the position outside the vehicle, but also to the position of the interior mirror near the windshield, which also satisfies the signal requirements.
In another embodiment, referring to fig. 3, the number of the bluetooth antennas 1 of the bluetooth module is multiple, wherein one bluetooth antenna 1 is combined and multiplexed with the 4G/5G antenna 2 through the multiplexing switch 3. The multiplex antenna is integrated with a plurality of 4G/5G antennas 2 on the roof of the vehicle (for example, shark fins or flat plate structures) to cover a preset area outside the vehicle, and other bluetooth antennas except the bluetooth antenna for forming the multiplex antenna are disposed inside the vehicle to cover an area inside the vehicle. The signal difference caused by the fact that the built-in Bluetooth antenna 1 is easily shielded by a metal car body can be avoided through the arrangement. Through multiplexing antenna with signal transmission to bluetooth module outside the car, realize corresponding function. By adopting the arrangement, under the condition that the Bluetooth antenna 1 in the vehicle cannot meet the application of the Bluetooth module, the Bluetooth module connected with the multiplexing antenna is used for increasing the signal intensity, so that the problem that the installation position of the vehicle networking terminal is limited due to the Bluetooth antenna 1 can be effectively solved under the condition that the cost is hardly increased, and the Bluetooth radio frequency performance is greatly improved.
In order to improve the user experience of the driver and enhance the keyless starting function of the vehicle, the other bluetooth antennas 1 except the multiplexing antenna are arranged in the area of the driver of the vehicle. Thus, when the driver approaches the bluetooth antenna 1, the signal strength is strongest and the antenna performance is good.
The bluetooth module is generally more in the condition of using when the driver is located the car, and it has corresponding use scene to be mostly under the condition that the vehicle is flame out moreover. Thus, the multiplex switch 3 has an on state and an off state, and the multiplex switch 3 is configured such that the multiplex switch 3 is in the on state when the vehicle is in the key-off state. Further, the multiplexing switch 3 is configured such that when the vehicle is in an off state and the multiplexing switch 3 is in an on state, the multiplexing switch 3 turns on the multiplexing antenna and the bluetooth module. Since the driver has left the vehicle at this time, when the driver uses the vehicle again, the bluetooth module is first used to open the door. Therefore, the setting can improve the reaction efficiency and further improve the user experience. Further, the multiplexing switch 3 is further configured such that when the bluetooth module and the 4G/5G module are simultaneously operated, the multiplexing switch 3 turns on the multiplexing antenna and the bluetooth module.
In a specific embodiment, the multiplexing switch 3 is a high frequency relay. The high-frequency relay is single-pole double-throw and can realize the switching function. It is understood that the multiplexing switch may also be a device commonly used by those skilled in the art to implement a switching function, and will not be described in detail herein.
The utility model also provides a bluetooth system, bluetooth system include the multiplexing antenna assembly of above-mentioned arbitrary embodiment, and the detailed structure and the theory of operation about multiplexing antenna assembly are no longer detailed here.
The present invention also provides a vehicle comprising a processor, a memory for storing processor-executable instructions, and the multiplexed antenna assembly 100 described in any of the above embodiments; the processor is configured to read the executable instructions from the memory, generate a control signal according to the executable instructions, and send the control signal to the multiplexing antenna assembly 100.
Specifically, under the condition of vehicle flameout, the application rate and the use frequency of the 4G/5G module are relatively low, and the 4G generally has 2 antennas, and the 5G generally has 4-6 antennas, so that one of the antennas can be multiplexed with the Bluetooth in a time-sharing manner, and the rate cannot be greatly influenced. When the Bluetooth module is provided with a plurality of Bluetooth antennas 1, the Bluetooth multiplexing 4G/5G antenna 2 only occurs under the condition that the self signal can not meet the application; when the Bluetooth module conflicts with the 4G/5G module application, namely the Bluetooth module and the 4G/5G module both need to use antenna signals, the multiplexing antenna is preferentially switched to the Bluetooth module application.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
