[0002] A Telematics Box (T-BOX) is a vehicle-to-everything (V2X) system comprised of four parts: a main unit, an in-vehicle T-BOX, a mobile app, and a backend system. The in-vehicle T-BOX primarily communicates with the backend system or the mobile app, enabling the app to display and control vehicle information. Antennas are also essential for V2X connectivity. In related technologies, the antenna box and T-BOX are often separated, leading to difficulties in layout and increased space requirements for the vehicle communication system. Utility Model Content

Detailed Implementation

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0033] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the definition under normal installation conditions of the vehicle-mounted T-Box provided in this disclosure, and "inner" and "outer" refer to the inner and outer contours of the corresponding components. Furthermore, when the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications.

[0034] like Figures 1 to 7 As shown, this disclosure provides a vehicle-mounted T-Box, which includes a housing 1 and a 5G antenna integrated within the housing 1. The 5G antenna is conformally attached to the inner wall of the housing 1. Here, "conformal attachment" means that the 5G antenna is attached to the inner wall of the housing 1, and the corresponding part of the 5G antenna and the inner wall of the housing 1 have the same shape. For example, if the inner wall of the housing 1 is arc-shaped, the 5G antenna has an arc segment with the same curvature. The 5G antenna can be integrated with the housing 1 through processes such as electroplating, LDS (Laser Direct Structuring), bonding, and FPC bonding. The specific design can be based on the shape and process requirements of the housing 1. Compared with the limited space inside the housing 1, the conformal attachment of the 5G antenna to the inner wall of the housing 1 provides more room for antenna structure design and better ensures antenna performance.

[0035] The vehicle-mounted T-Box disclosed herein integrates the 5G antenna and the vehicle-mounted T-Box into a single design, combining the antenna box and the vehicle-mounted T-Box into one unit. This reduces the space occupied and volume, simplifies placement, lowers the difficulty of vehicle layout, and saves space. Eliminating the losses caused by RF wiring harness connections effectively improves the antenna's radiation efficiency, contributing to enhanced communication performance. Furthermore, the 5G antenna is conformally attached to the inner wall of the housing 1, without occupying the installation space of existing components within the T-Box. The closer proximity of the 5G antenna to the modules within the T-Box results in lower line loss and optimal antenna performance.

[0036] The structure and number of 5G antennas are not specifically limited in this disclosure. In the embodiments provided in this disclosure, such as Figure 2 and Figure 5 As shown, a 5G main antenna 21, a 5G secondary antenna 22, a first MIMO antenna 23, and a second MIMO antenna 24 are conformally disposed on the inner wall of the housing 1. Of course, this disclosure also includes embodiments with any one or more of the above four antennas. The structure and function of the above antennas will be described in detail below.

[0037] In one embodiment of this disclosure, such as Figure 1 As shown, the shell 1 has a top wall and opposing first side walls. A stepped portion 10 is provided at the connection between the top wall and the first side walls. The number of steps and the height of the stepped portion 10 are not limited; it can be single-step or multi-step. Figure 2 As shown, the 5G main antenna 21 and the 5G secondary antenna 22 have bends 200 that fit into the stepped portion 10. The antenna structure affects the operating frequency band it covers. The operating frequency bands that the 5G main antenna 21 and the 5G secondary antenna 22 can cover include 690-960MHz, 1710-2690MHz, and 3300-5000MHz. In this embodiment, a conformal attachment arrangement is adopted, which can ensure that the profile height of the 5G antenna is less than or equal to the height of the first sidewall. The profile height is low, for example, it can be 30mm, which is convenient for vehicle deployment and can meet the installation requirements of low profile height in vehicles.

[0038] In one exemplary embodiment of this disclosure, such as Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, the 5G main antenna 21 and the 5G sub-antenna 22 each have a first branch 201 and a second branch 202 arranged in parallel, and a first intermediate branch 203 connecting the first branch 201 and the second branch 202. A bend 200 is disposed on the first branch 201 and / or the second branch 202. The 5G main antenna 21 and the 5G sub-antenna 22 are designed as U-shaped structures. In other embodiments, they can also be L-shaped, various irregular structures, etc. Through the structural design of the main and sub-antennas, the antennas themselves can cover the corresponding operating frequency bands.

[0039] In this disclosure, the first stub 201 of the 5G main antenna 21 and the 5G sub-antenna 22 has multiple segments of varying widths, such as... Figure 8 and Figure 9 As shown, the first branch 201 has at least a first segment 2011 located at the end and a second segment 2012 near the first intermediate branch 203. The width of the first segment 2011 is greater than the width of the second segment 2012. The first branch 201 adopts a multi-segment structure with unequal widths, and is not limited to the first segment 2011 and the second segment 2012 shown in the figure; it can be designed as needed. A feed point 2000 is provided on the first segment 2011. The width of the first segment 2011 gradually decreases from the end to the second segment 2012. This decrease can be uniform or irregular, both of which fall within the protection scope of this disclosure. The feed positions of the 5G main antenna 21 and the 5G sub-antenna 22 adopt a gradient structure design to achieve broadband matching of high-frequency impedance.

[0040] The ends of the second branch 202 of the 5G main antenna 21 and the 5G secondary antenna 22 are DC grounded, which achieves good matching with the low frequency band and thus can achieve full-band bandwidth coverage.

[0041] The 5G antenna includes a first MIMO antenna 23 and a second MIMO antenna 24. MIMO (Multiple-Input Multiple-Output) antennas employ multiple spatial channels for data transmission and reception, and MIMO technology can improve channel capacity. The 5G main antenna 21 and the 5G secondary antenna 22 support the entire 5G frequency band and are compatible with all 4G frequency bands. The first MIMO antenna 23 and the second MIMO antenna 24 cover the operating frequency bands of 1710-2690MHz and 3300-5000MHz, supporting the 4G mid-band and the entire 5G frequency band. The 5G main antenna 21 and the 5G secondary antenna 22 are respectively connected to the main receiving branch and the auxiliary receiving branch of the T-Box, enabling simultaneous transmission. The first MIMO antenna 23 and the second MIMO antenna 24 mainly implement diversity reception, achieving 5G 4MIMO reception. In this embodiment, the first MIMO antenna 23 and the second MIMO antenna 24 are disposed on the second sidewall of the housing 1 adjacent to the first sidewall. The first MIMO antenna 23 and the second MIMO antenna 24 are attached to the same second sidewall and arranged at intervals. The positions of the four antennas can be adjusted and set as needed. A battery 3 is provided inside the housing 1, and the second MIMO antenna 24 can be disposed close to the battery 3.

[0042] The structures of the first MIMO antenna 23 and the second MIMO antenna 24 can be varied. In an exemplary embodiment of this disclosure, such as Figure 3 , Figure 7 , Figure 10 and Figure 11 As shown, the first MIMO antenna 23 and the second MIMO antenna 24 have similar structures, with a third branch 204 and a fourth branch 205 arranged opposite to each other, and a second intermediate branch 206 connecting the third branch 204 and the fourth branch 205. Similarly, the third branch 204 is provided with a feed point 2000. The width of the third branch 204 gradually decreases from the end to the second intermediate branch 206. It also adopts the design concept of impedance gradient at the feed position to ensure broadband matching in the high-frequency band.

[0043] The fourth branch 205 of the first MIMO antenna 23 and the second MIMO antenna 24 is coupled to ground, which can achieve matching of the intermediate frequency band. All four antennas adopt a U-shaped structure design, which can achieve high frequency band coverage. The 5G main antenna 21 and the 5G secondary antenna 22 are directly grounded to achieve low frequency coverage, and the first MIMO antenna 23 and the second MIMO antenna 24 are coupled to ground to achieve intermediate frequency coverage. Thus, low, medium and high frequency band coverage can be achieved, and the overall size of the antenna can be effectively compressed to achieve miniaturized antenna design. Under the premise of ensuring antenna performance, it can be arranged in a space-limited housing 1.

[0044] In this disclosure, such as Figure 7 , Figure 10 and Figure 11 As shown, the first MIMO antenna 23 and the second MIMO antenna 24 also have a fifth branch 207 that overlaps on the stepped portion 10. The structure design of multiple branches can adjust the operating frequency band covered by the antenna and the impedance matching, and its structure can be designed as needed.

[0045] In this disclosure, an isolation hole 208 is provided on one of the 5G main antenna 21 and the 5G secondary antenna 22, and on one of the first MIMO antenna 23 and the second MIMO antenna 24. In this embodiment, the isolation holes 208 are provided on the 5G secondary antenna 22 and the first MIMO antenna 23. The number and shape of the isolation holes 208 are not limited. They can reduce the coupling between the antenna and the metal structure inside the housing 1, ensure the normal operation and impedance matching of the antenna itself, and improve the isolation.

[0046] Furthermore, in this disclosure, such as Figure 2 As shown, a 4G antenna 25 is also provided inside the housing 1, and the 4G antenna 25 is located close to the 5G secondary antenna 22 inside the housing 1. The 4G antenna 25 can serve as a backup 4G antenna to ensure antenna performance.

[0047] The housing 1 is equipped with a TPMS (Tire Pressure Monitoring System) receiving antenna 26. The TPMS receiving antenna 26 is positioned close to the first MIMO antenna 23 or the second MIMO antenna 24, which can better receive the tire pressure information of the vehicle.

[0048] The vehicle-mounted T-Box disclosed herein integrates four 5G antennas. The antenna impedance matching supports full-band coverage across low, mid, and high frequencies. Specifically, the VSWR (Voltage Standing Wave Ratio) is <3 and the isolation is >7dB in the 690-960MHz band; the VSWR is <3 and the isolation is >15dB in the 1710-2690MHz band; and the VSWR is <2.5 and the isolation is >16dB in the 3300-5000MHz band. The antennas exhibit high isolation, enabling better MIMO performance and throughput. These four antennas achieve broadband matching entirely on their own, offering advantages such as high gain and high efficiency. The antennas themselves do not require additional matching circuitry, reducing manufacturing complexity and cost.

[0049] According to a second aspect of this disclosure, a vehicle is provided that includes the vehicle-mounted T-Box described above. This vehicle possesses all the beneficial effects of the vehicle-mounted T-Box described above, which will not be elaborated upon here. Multiple antennas in the vehicle-mounted T-Box communicate with the vehicle's infotainment system using digital signal harnesses, effectively reducing harness costs.

[0054] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures.

It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0055] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0056] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0057] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0058] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0059] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
