Description

Technical Field

[0001] This application relates to the field of automotive antenna technology, specifically to an automotive antenna system and an automotive vehicle. Background Technology

[0002] With the continuous advancement of intelligent connected vehicle technology, information interaction between vehicles and the outside world is becoming more frequent. As an essential interface for wireless information interaction, the performance requirements of antennas directly affect the security and reliability of intelligent connected functions. With the application of a series of intelligent connected systems such as satellite navigation systems, 4G communication, 5G communication, autonomous driving systems, and C-V2X in vehicles, the performance requirements for on-board antenna systems are becoming increasingly stringent to ensure the vehicle's wireless information interaction capabilities.

[0003] Currently, the most commonly used antenna structures are hidden or built-in, such as shark fin antennas and built-in antennas. However, as the complexity of automotive application environments increases, the communication signal of antennas will be affected in weak network environments such as tunnels and garages. The signal reception capability of hidden and built-in antennas is relatively weaker than that of extendable antennas, thus affecting the performance of intelligent connected vehicles. Therefore, it is necessary to select antenna layout schemes with higher signal strength to ensure their communication capabilities. Utility Model Content

[0021] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0022] Figure 1 This is a schematic diagram of the structure of an automotive antenna system provided in an exemplary embodiment of this application. Figure 1 As shown, the automotive antenna system includes an antenna conductor 1 and an antenna harness 2. The antenna conductor 1 is located at the rear corner window 3 of the vehicle, and the antenna harness 2 connects the antenna conductor 1 to the vehicle's onboard T-BOX.

[0023] Since the position of antenna conductor 1 affects its distance from interfering components and the length of antenna harness 2, thus affecting the signal strength received by the antenna, for example, experimental tests have shown that the closer the antenna conductor 1 is to the car's roof panel, the weaker the signal strength received by the antenna conductor 1. Therefore, this application positions the antenna conductor 1 at the rear corner window 3, away from the car's roof panel, to ensure the signal strength received by the antenna conductor 1 without affecting the car's appearance. This application uses antenna harness 2 to connect antenna conductor 1 and the vehicle-mounted T-BOX to achieve a wired connection between antenna conductor 1 and the vehicle-mounted T-BOX, further improving the signal transmission efficiency between antenna conductor 1 and the vehicle-mounted T-BOX while reducing the unreliability caused by wireless communication.

[0024] This application provides an automotive antenna system that includes an antenna conductor positioned at the rear corner window of the vehicle, and an antenna harness connecting the antenna conductor to the vehicle's onboard T-BOX. By placing the antenna conductor at the rear corner window and connecting it to the vehicle's onboard T-BOX via the antenna harness, the system enables intelligent networking functionality for the vehicle. This not only utilizes the reduced interference at the rear corner window location to improve antenna gain and thus enhance the received signal strength, but also allows the antenna conductor to be concealed within the rear corner window, reducing the impact of the external antenna on the vehicle's overall wind resistance and improving the vehicle's aesthetics.

[0025] In one embodiment, the antenna conductor 1 and the vehicle-mounted T-BOX can be located on the same side of the vehicle.

[0026] Since the length of the antenna harness 2 directly affects the communication signal strength between the antenna conductor 1 and the vehicle-mounted T-BOX, the shorter the length of the antenna harness 2, the stronger the communication signal between the antenna conductor 1 and the vehicle-mounted T-BOX. Therefore, this application allows the antenna conductor 1 and the vehicle-mounted T-BOX to be set on the same side of the vehicle to minimize the distance between the antenna conductor 1 and the vehicle-mounted T-BOX, thereby shortening the length of the antenna harness 2 and improving the communication signal strength between the antenna conductor 1 and the vehicle-mounted T-BOX.

[0027] It should be understood that this application can select the relative positional relationship between the antenna conductor 1 and the vehicle-mounted T-BOX according to the needs of the actual application scenario. For example, the antenna conductor 1 and the vehicle-mounted T-BOX can be set on different sides of the car, but as close as possible and in a position that is convenient for wiring. While ensuring the communication signal strength between the antenna conductor 1 and the vehicle-mounted T-BOX, the layout of the antenna harness 2 can also be taken into account. As long as the selected relative positional relationship between the antenna conductor 1 and the vehicle-mounted T-BOX can ensure the communication signal strength between the antenna conductor 1 and the vehicle-mounted T-BOX, this application does not limit the relative positional relationship between the antenna conductor 1 and the vehicle-mounted T-BOX.

[0028] In one embodiment, the antenna conductor 1 may be disposed on the side of the rear corner window 3 away from the roof of the vehicle.

[0029] When the distance between the antenna conductor 1 and the car's roof panel is too close, the received signal strength of the antenna conductor 1 is weak. In environments with weak network conditions such as tunnels and garages, this may cause the in-vehicle T-BOX to be unable to connect to the network or experience signal delays, thus affecting the car's intelligent services, such as navigation. Therefore, this application positions the antenna conductor 1 on the rear corner window 3, away from the car roof, that is, at the bottom area of ​​the rear corner window 3, to maximize the distance between the antenna conductor 1 and the car's roof panel, thereby increasing the communication signal strength between the antenna conductor 1 and the in-vehicle T-BOX.

[0030] It should be understood that the specific position of the antenna conductor 1 on the rear corner window 3 can be selected according to the needs of the actual application scenario. For example, the antenna conductor 1 can also be set on the lateral side of the rear corner window 3, as long as the specific position of the selected antenna conductor 1 on the rear corner window 3 can ensure the communication signal strength between the antenna conductor 1 and the vehicle T-BOX. The specific position of the antenna conductor 1 on the rear corner window 3 is not limited in this application.

[0031] In one embodiment, such as Figure 1 As shown, the antenna conductor 1 can be disposed on the outer surface of the glass of the rear corner window 3.

[0032] This application allows the antenna conductor 1 to be disposed on the outer surface of the glass of the rear corner window 3, thereby reducing the signal attenuation effect of the glass of the rear corner window 3 and thus maximizing the signal strength received by the antenna conductor 1. Optionally, this application allows the antenna guide 1 to be arranged on the outer surface of the glass of the rear corner window 3 by printing or coating, so as not to affect the external shape of the rear corner window 3 while ensuring the function of the antenna conductor 1, thus ensuring overall aesthetics.

[0033] Figure 2 This is a schematic diagram of the structure of an automotive antenna system provided in another exemplary embodiment of this application. (See diagram below.) Figure 2As shown, the antenna conductor 1 can be embedded in the glass of the rear corner window 3.

[0034] Since the glass of the rear corner window 3 is usually multi-layered, this application can place the antenna conductor 1 in the glass of the rear corner window 3 to reduce the damage to the antenna conductor 1 caused by external factors, such as wear from foreign objects or short circuits. This application places the antenna conductor 1 in the glass of the rear corner window 3 to protect the antenna conductor 1 without affecting the external structure of the rear corner window 3, thus ensuring the overall aesthetics.

[0035] Figure 3 This is a schematic diagram of the structure of an automotive antenna system provided in another exemplary embodiment of this application. (See diagram below.) Figure 3 As shown, the antenna conductor 1 can be disposed on the inner surface of the glass of the rear corner window 3.

[0036] This application allows the antenna conductor 1 to be disposed on the inner surface of the glass of the rear corner window 3, so as to realize the convenient connection between the antenna conductor 1 and the vehicle T-BOX by using internal wiring. At the same time, it can reduce the risk of the antenna harness 2 being exposed to the outside of the car, thereby reducing the risk of damage to the antenna harness 2, and thus improving the communication stability between the antenna conductor 1 and the vehicle T-BOX.

[0037] It should be understood that the specific position of the antenna conductor 1 on the rear corner window 3 can be selected according to the needs of the actual application scenario. The antenna conductor 1 can also be set on the outer surface, inner surface, or middle layer of the rear corner window 3, or it can be set on the side of the rear corner window 3. As long as the specific position of the antenna conductor 1 on the rear corner window 3 can ensure the communication signal strength between the antenna conductor 1 and the vehicle T-BOX, and the safety and reliability of the antenna conductor 1 and the antenna harness 2, the specific position of the antenna conductor 1 on the rear corner window 3 is not limited.

[0038] In one embodiment, such as Figure 1-3 As shown, the antenna conductor 1 can be disposed in the contact area between the sealing strip 4 of the rear corner window 3 and the rear corner window 3.

[0039] This application allows the antenna conductor 1 to be placed in the contact area between the sealing strip 4 of the rear corner window 3 and the rear corner window 3, that is, the antenna conductor 1 is placed between the sealing strip 4 of the rear corner window 3 and the rear corner window 3, so as to protect the antenna conductor 1 by using the sealing strip 4, preventing foreign objects from entering the antenna conductor 1 and affecting its performance or damaging the antenna conductor 1. In addition, the sealing strip 4 can also be used to cover the antenna conductor 1 to avoid the antenna conductor 1 affecting the appearance of the rear corner window 3.

[0040] It should be understood that the specific position of the antenna conductor 1 on the rear corner window 3 can be selected according to the needs of the actual application scenario. For example, the antenna conductor 1 can be set in the rear corner window 3 away from the sealing strip 4 (for example, when the antenna conductor 1 is embedded in the glass of the rear corner window 3). As long as the specific position of the antenna conductor 1 on the rear corner window 3 can ensure the communication signal strength between the antenna conductor 1 and the vehicle T-BOX and the safety and reliability of the antenna conductor 1, this application does not limit the specific position of the antenna conductor 1 on the rear corner window 3.

[0041] In one embodiment, the shape of the antenna conductor 1 may include any of the following shapes: linear, polygonal, and ring-shaped.

[0042] This application can set the shape of the antenna conductor 1 according to actual needs, such as linear, polygonal and ring shape, etc., and this application can also set multiple antenna conductors 1 to different shapes according to actual needs, so as to make full use of the advantages of antenna conductors 1 of various shapes in different scenarios, and ensure that the signal strength received by antenna conductor 1 in different scenarios can meet the needs of vehicle networking.

[0043] It should be understood that the antenna conductor 1 of this application may be selected in different shapes according to the needs of the actual application scenario, as long as the shape of the selected antenna conductor 1 can ensure the communication signal strength between the antenna conductor 1 and the vehicle-mounted T-BOX. The specific shape of the antenna conductor 1 is not limited in this application.

[0044] In one embodiment, the receiving network frequency band of the antenna conductor 1 may include any one of the following frequency bands: N41, N8, and N3.

[0045] This application achieves the reception of corresponding network signals by setting the receiving network frequency band of antenna conductor 1. Among them, N41 refers to the 5G frequency band with a bandwidth of 160MHz and a frequency band of 2515MHz-2675MHz, N8 refers to the 2G, 3G and 4G frequency bands of 900MHz, and N3 refers to the network with a frequency range of 1710MHz-1785MHz (uplink) and 1805MHz-1880MHz (downlink).

[0046] It should be understood that this application may select the receiving network frequency band of antenna conductor 1 according to the needs of the actual application scenario, such as the N78, N79, N5, etc., as long as the selected receiving network frequency band of antenna conductor 1 ensures the intelligent networking of the vehicle. This application does not limit the specific receiving network frequency band of antenna conductor 1.

[0047] This application also provides a vehicle, including: an on-board T-BOX; and an automotive antenna system for any of the above.

[0048] This application provides a vehicle that incorporates an antenna conductor located at the rear corner window of the vehicle, and an antenna harness connecting the antenna conductor to the vehicle's onboard T-BOX. By placing the antenna conductor at the rear corner window and connecting it to the vehicle's onboard T-BOX via the antenna harness, the vehicle achieves intelligent networking functionality. This not only utilizes the low interference at the rear corner window location to improve antenna gain and thus enhance the received signal strength, but also allows the antenna conductor to be concealed within the rear corner window, reducing the impact of the external antenna on the vehicle's overall wind resistance and improving the vehicle's aesthetics.
