Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to an antenna, a remote information processor, and a vehicle. Background Technology

[0002] With the continuous development of networking, the design focus of equipment applied in the field of communication technology has shifted to areas such as device miniaturization (compact size) and easy integration.

[0003] However, existing antennas often need to be large in size to achieve good communication functions, which often results in a large connection area between the antenna and the circuit board. This is not conducive to the arrangement of other modules on the circuit board. In addition, the antenna also needs to have a certain clearance between it and metal components to ensure that the antenna works properly. Therefore, remote information processors that include antennas and circuit boards often need to be large in size, which reduces the compactness of the internal structure of the remote information processor.

To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended only to explain this application and not to limit it.

[0046] With the continuous development of networking, the design focus of devices applied in the field of communication technology has shifted to miniaturization (compact size) and ease of integration. However, existing antennas often require a relatively large size to achieve good communication functions, resulting in a large connection area between the antenna and the circuit board. This is not conducive to the arrangement of other modules on the circuit board, and the antenna also requires a certain clearance between itself and metal components to ensure normal operation. Therefore, remote information processors that include antennas and circuit boards often need to be relatively large, reducing the compactness of the internal structure of the remote information processor.

[0047] To address the aforementioned technical problems, this application is provided. To better understand this application, the antenna, telematics processor, and vehicle according to embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram showing the connection between antenna 1 and circuit board 2 in some embodiments of this application. Figure 2This is a schematic diagram of the structure of antenna 1 according to some embodiments of this application. In the figure, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The first direction X, the second direction Y, and the third direction Z intersect each other.

[0049] like Figure 1 and Figure 2 As shown, this application embodiment provides an antenna 1, which includes a main body 11, a feed section 12, and a grounding section 13. The main body 11 is plate-shaped. The feed section 12 includes a first body 121 and a feed pin 122. The feed pin 122 is used to connect to the microstrip line of the circuit board 2. The feed pin 122 and the main body 11 are spaced apart in a first direction X. The first body 121 is connected between the main body 11 and the feed pin 122. The grounding section 13 includes a second body 131 and a grounding pin 132. The grounding pin 132 is used to connect to the ground terminal of the circuit board 2. The grounding pin 132 and the main body 11 are spaced apart in a first direction X. The second body 131 is connected between the main body 11 and the grounding pin 132. The first direction X is the thickness direction of the main body 11.

[0050] like Figure 1 and Figure 2 As shown in the figure, an antenna 1 provided in this application embodiment includes a main body 11, a feed part 12, and a grounding part 13. The feed part 12 includes a feed pin 122 and a first body 121. The antenna 1 can be fed by connecting to a microstrip line in a circuit board 2 through the feed pin 122. The grounding part 13 includes a ground pin 132 and a second body 131. The antenna 1 can be grounded by connecting to a ground terminal in the circuit board 2 through the ground pin 132. The main body 11 is plate-shaped. The first body 121 is connected between the feed pin 122 and the main body 11, and the second body 131 is connected between the ground pin 132 and the main body 11. This allows the main body 11 to achieve communication across multiple frequency bands after the antenna 1 is connected to the circuit board 2. Furthermore, since the antenna 1 is connected to the circuit board 2 through the feed part 12 and the grounding part 13, the circuit board 2 only needs to reserve positions for connecting to the feed pin 122 and the grounding pin 132, which facilitates the arrangement of other modules on the circuit board 2 and improves the flexibility of the relative position setting between the antenna 1 and the circuit board 2. By setting the power supply pin 122 and the main body 11 to be spaced apart along the first direction X, and setting the grounding pin 132 and the main body 11 to be spaced apart along the first direction X, a certain distance can be maintained between the main body 11 and the circuit board 2 in the first direction X. This distance can serve as the clearance required between the antenna 1 and other metal components, allowing some modules on the circuit board 2 to be placed below the antenna 1 without easily interfering with the normal operation of the antenna 1. It also allows the circuit board 2 to be directly mounted on the metal floor of the remote information processor, greatly improving the compactness of the internal structure of the remote information processor.

[0051] In some embodiments, the antenna 1 provided in this application can be used to implement communication in 2G / 3G / 4G / 5G frequency bands. The antenna 1 provided in this application can be connected to a circuit board 2 such as a PCB (Printed Circuit Board). In some embodiments, the circuit board 2 has multiple pads. The feed pin 122 can be electrically connected to a microstrip line through one of the pads on the circuit board 2 to feed the antenna 1, and the ground pin 132 can be electrically connected to a ground terminal through another pad on the circuit board 2 to ground the antenna 1.

[0052] This application does not limit the material of antenna 1. In some embodiments, antenna 1 can be made of metal, which enables antenna 1 to have good working performance and structural strength while having a low manufacturing cost.

[0053] like Figure 1 and Figure 2 As shown, this application does not limit the distance between the feed pin 122 and the main body 11, nor the distance between the grounding pin 132 and the main body 11. The distance between the feed pin 122 and the main body 11 can be set according to the performance of the antenna 1, the clearance required by the antenna 1, and the arrangement of the modules on the circuit board 2. The distance between the grounding pin 132 and the main body 11 can also be set according to the performance of the antenna 1, the clearance required by the antenna 1, and the arrangement of the modules on the circuit board 2. This allows the main body 11 and the circuit board 2 to have a suitable distance after the antenna 1 is connected, reducing the interference of metal devices on the antenna 1 and facilitating a more compact arrangement of the modules on the circuit board 2.

[0054] like Figure 1 and Figure 2 As shown, in some embodiments, the power supply pin 122 and the grounding pin 132 are located on the same side of the main body 11 in the first direction X, that is, the power supply part 12 and the grounding part 13 are located on the same side of the main body 11 in the first direction X. The distance between the power supply pin 122 and the main body 11 in the first direction X can be equal to the distance between the grounding pin 132 and the main body 11 in the first direction X, so that the antenna 1 and the circuit board 2 are not easily affected by vibration and will not have relative displacement, thereby improving the connection stability between the antenna 1 and the circuit board 2.

[0055] This application does not limit the angle between the surface of the first body 121 and the surface of the main body 11, nor the angle between the surface of the second body 131 and the surface of the main body 11. The angle between the surface of the first body 121 and the surface of the main body 11 can be set according to the arrangement of the modules on the circuit board 2, and the angle between the surface of the second body 131 and the surface of the main body 11 can also be set according to the arrangement of the modules on the circuit board 2, so that there can be a suitable gap between the main body 11 and the circuit board 2, thereby allowing some modules on the circuit board 2 to be placed below the antenna 1 without easily interfering with the normal operation of the antenna 1.

[0056] like Figure 1 and Figure 2 As shown, in some embodiments, the angle between the surface of the first body 121 and the surface of the main body 11 is 90°; and / or, the angle between the surface of the second body 131 and the surface of the main body 11 is 90°, so that there is a relatively sufficient gap between the main body 11 and the circuit board 2. When the angle between the surface of the first body 121 and the surface of the main body 11 and the angle between the surface of the second body 131 and the surface of the main body 11 are both 90°, the vibration resistance of the antenna 1 can be improved, thereby improving the connection stability between the antenna 1 and the circuit board 2.

[0057] like Figure 1 and Figure 2 As shown, in some embodiments, the main body 11 extends along a ring path and connects to the feed section 12 to form a closed ring, with the feed section 12 and the ground section 13 spaced apart along the ring path. By extending the main body 11 along the ring path, the main body 11 can have a good extension length, enabling it to perform better communication on multiple frequency bands. By connecting the main body 11 and the feed section 12 to form a closed ring, and with the feed section 12 and the ground section 13 spaced apart along the ring path, the antenna 1 can have a more stable structure, making it less susceptible to deformation due to vibration after the antenna 1 is connected to the circuit board 2, thus improving the connection stability between the antenna 1 and the circuit board 2, as well as the operational stability of the antenna 1.

[0058] like Figure 1 and Figure 2 As shown, in some embodiments, there are two or more grounding portions 13, which are spaced apart along a circular path. When the size of the main body 11 is too large, the working performance of the antenna 1 and the connection stability between the antenna 1 and the circuit board 2 can be improved by reasonably adjusting the spacing between the grounding portions 13.

[0059] like Figure 2As shown, in some embodiments, the antenna 1 further includes a support portion 14, which includes a third body 141 and a support foot 142. The support foot 142 and the main body 11 are spaced apart in the first direction X. The third body 141 is connected between the main body 11 and the support foot 142. The support portion 14, the feed portion 12, and the ground portion 13 are located on the same side of the main body 11 in the first direction X. By providing the support portion 14, the connection stability between the antenna 1 and the circuit board 2 can be further improved, making the antenna 1 less susceptible to deformation due to vibration after being connected to the circuit board 2.

[0060] like Figure 2 As shown, in some embodiments, the support foot 142, the feed foot 122, and the ground foot 132 can be located on the same side of the main body 11 in the first direction X. That is, the support part 14, the feed part 12, and the ground part 13 are located on the same side of the main body 11 in the first direction X. The distance between the support foot 142 and the main body 11 in the first direction X can be equal to the distance between the feed foot 122 and the main body 11 in the first direction X and the distance between the ground foot 132 and the main body 11 in the first direction X. This makes it less susceptible to vibration and relative displacement after the antenna 1 and the circuit board 2 are connected, thereby further improving the connection stability between the antenna 1 and the circuit board 2.

[0061] like Figure 2 As shown, in some embodiments, the angle between the surface of the third body 141 and the surface of the main body 11 can be 90° to improve the vibration resistance of the antenna 1 and the connection stability between the antenna 1 and the circuit board 2.

[0062] like Figure 2 As shown, in some embodiments, the main body 11, the power supply part 12, the grounding part 13 and the support part 14 can be integrally formed, that is, the main body 11, the power supply part 12, the grounding part 13 and the support part 14 can be formed by cutting, stamping or bending a substrate plate.

[0063] like Figure 2 As shown, in some embodiments, there are two grounding portions 13, which are spaced apart along the third direction Z. The support portion 14 and the feed portion 12 are spaced apart along the second direction Y. The first direction X, the second direction Y, and the third direction Z intersect each other. By setting the two grounding portions 13 spaced apart along the third direction Z and the support portion 14 and the feed portion 12 spaced apart along the second direction Y, the antenna 1 has good structural stability in the second direction Y and the third direction Z after being connected to the circuit board 2, and is not easily deformed by vibration.

[0064] like Figure 2As shown, in some embodiments, the main body 11 includes a first antenna arm 111 and a second antenna arm 112. The first antenna arm 111, the second antenna arm 112, and the feed section 12 are interconnected to form a closed ring and are surrounded by a hollow portion 1a. The first antenna arm 111 extends along the second direction Y and one end of the first antenna arm 111 is connected to the feed section 12. The second antenna arm 112 includes a first segment 112a, a second segment 112b, a third segment 112c, and a fourth segment 112d. The first segment 112a is connected to the second segment 112b and the feed section 12. Between sections 12, the end of the second segment 112b furthest from the first segment 112a is connected to the third segment 112c. The end of the third segment 112c furthest from the second segment 112b is connected to the end of the first antenna arm 111 furthest from the feed section 12. The fourth segment 112d is connected to the side of the third segment 112c near the hollowed-out section 1a and protrudes from the third segment 112c in the third direction Z. The first segment 112a and the third segment 112c extend in the second direction Y, and the second segment 112b and the fourth segment 112d extend in the third direction Z. By bending each segment of the second antenna arm 112, the antenna 1 can achieve a better structural compactness while ensuring that the second antenna arm 112 has a good extension length.

[0065] By connecting the end of the third segment 112c away from the second segment 112b to the end of the first antenna arm 111 away from the feed section 12, the relative movement between the first antenna arm 111 and the second antenna arm 112 can be restricted, thereby improving the structural stability of the antenna 1.

[0066] like Figure 2 As shown, in some embodiments, the support portion 14 is connected to the second segment 112b; one of the two ground portions 13 is connected to the first segment 112a, and the other ground portion 13 is connected to the fourth segment 112d, so as to further improve the connection stability between the antenna 1 and the circuit board 2.

[0067] like Figure 2 As shown, in some embodiments, the grounding portion 13 connected to the first segment 112a is located on the side of the first segment 112a away from the cutout portion 1a in the third direction Z, the grounding portion 13 connected to the fourth segment 112d is located on the side of the fourth segment 112d in the second direction Y, and the support portion 14 is located on the side of the second segment 112b away from the feed portion 12 in the second direction Y. By setting the support portion 14 and the grounding portion 13 connected to the first segment 112a to be located on the side of the main body 11 away from the cutout portion 1a, the antenna 1 has better structural stability after being connected to the circuit board 2, thereby enabling the antenna 1 to have better vibration resistance.

[0068] By setting the grounding part 13 connected to the fourth segment 112d to be located on one side of the fourth segment 112d in the second direction Y, the fourth segment 112d does not need to have a wide width in the second direction Y, and the fourth segment 112d can have a better extension dimension in the third direction Z, so that the antenna 1 has better working performance.

[0069] This application does not limit the specific extension lengths of the first antenna arm 111 and the second antenna arm 112. In some embodiments, the antenna 1 can achieve communication in 2G / 3G / 4G / 5G frequency bands by using reasonable extension lengths of the first antenna arm 111 and the second antenna arm 112. In some embodiments, the extension length of the second antenna arm 112 is 115mm to 117mm, so that the main body 11 can have a relatively compact structural size while also having good communication performance. Preferably, the extension length of the second antenna arm 112 can be 116mm.

[0070] Figure 3 This is a top view of antenna 1 according to some embodiments of this application.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments, a first reinforcing part 11a is provided on the main body 11. The extension path of the first reinforcing part 11a is the same as the extension path of at least part of the main body 11. The first reinforcing part 11a is provided protruding from the surface of the main body 11, so that the first reinforcing part 11a can improve the deformation resistance of the main body 11 and improve the structural stability of the main body 11.

[0072] In some embodiments, the extension path of the first reinforcing part 11a may be the same as the extension paths of the first antenna arm 111, the first segment 112a, the second segment 112b and the third segment 112c. Since the size of the fourth segment 112d of the second antenna arm 112 cannot be set too large due to the shape limitation of the hollow part 1a, the first reinforcing part 11a may not be provided on the fourth segment 112d.

[0073] like Figure 2 and Figure 3 As shown, in some embodiments, the first reinforcing part 11a is provided on the surface of the main body part 11 near the power supply part 12 in the first direction X, so that the main body part 11 is not prone to bending deformation in the first direction X toward the side with the power supply part 12, the grounding part 13 and the support part 14, thereby improving the structural stability of the main body part 11.

[0074] In some embodiments, the first reinforcing part 11a and the main body part 11 can be integrally formed, that is, the main body part 11 and the first reinforcing part 11a can be formed by stamping or cutting a substrate plate, so that the first reinforcing part 11a can be recessed in the first direction X relative to the surface of the main body part 11 on the side away from the power supply part 12.

[0075] Figure 4 This is a side view of antenna 1 according to some embodiments of this application. Figure 5 This is a front view of antenna 1 according to some embodiments of this application.

[0076] like Figures 2 to 5 As shown, in some embodiments, the first body 121 is connected to the main body 11 via a first bend 12a, and a second reinforcing portion 12b is provided on the first bend 12a. The second reinforcing portion 12b extends from the main body 11 toward the first body 121 and protrudes from the surface of the first bend 12a; and / or, the second body 131 is connected to the main body 11 via a second bend 13a, and a third reinforcing portion 13b is provided on the second bend 13a. The third reinforcing portion 13b extends from the main body 11 toward the second body 131 and protrudes from the surface of the second bend 13a. By providing a second reinforcing part 12b protruding from the surface of the first bending part 12a and a third reinforcing part 13b protruding from the surface of the second bending part 13a, the second reinforcing part 12b and the third reinforcing part 13b can respectively improve the deformation resistance of the first bending part 12a and the second bending part 13a, making it less likely for bending deformation to occur between the feed part 12 and the ground part 13 and the main body part 11, thereby improving the structural stability of the antenna 1.

[0077] In some embodiments, there may be two first bending portions 12a, which can be used to connect to the first antenna arm 111 and the second antenna arm 112, respectively. In some embodiments, there may be two second reinforcing portions 12b, which are located on the two first bending portions 12a, and one end of the two second reinforcing portions 12b can be connected to the first reinforcing portion 11a on the first antenna arm 111 and the first reinforcing portion 11a on the second antenna arm 112, respectively.

[0078] In some embodiments, the second reinforcing portion 12b protrudes from the surface of the first bent portion 12a toward the side facing the feed portion 12 and the main body portion 11; and / or, the third reinforcing portion 13b protrudes from the surface of the second bent portion 13a toward the side facing the ground portion 13 and the main body portion 11, so that the feed portion 12 and the ground portion 13 are less likely to be bent and deformed toward the side facing the main body portion 11, thereby improving the structural stability of the antenna 1.

[0079] In some embodiments, the second reinforcing portion 12b, the first bending portion 12a, the main body portion 11, and the power supply portion 12 can be integrally formed. That is, the second reinforcing portion 12b, the first bending portion 12a, the main body portion 11, and the power supply portion 12 can be formed by cutting, stamping, or bending a substrate plate, such that the second reinforcing portion 12b is recessed on the surface of the first bending portion 12a away from the power supply portion 12 and the main body portion 11.

[0080] In some embodiments, the third reinforcing portion 13b, the second bending portion 13a, the main body portion 11, and the grounding portion 13 can be integrally formed, that is, the third reinforcing portion 13b, the second bending portion 13a, the main body portion 11, and the grounding portion 13 can be formed by cutting, stamping, or bending a substrate plate, such that the third reinforcing portion 13b is recessed on the surface of the second bending portion 13a away from the grounding portion 13 and the main body portion 11.

[0081] In some embodiments, the maximum dimension of the first body 121 of the power supply section 12 in the third direction Z can be the same as the maximum dimension of the main body 11 in the third direction Z, so as to improve the power supply effect and connection strength between the power supply section 12 and the main body 11.

[0082] like Figure 5 As shown, in some embodiments, a fourth reinforcing part 12c is provided on the first body 121. The fourth reinforcing part 12c extends and is formed along the first direction X. The fourth reinforcing part 12c protrudes from the surface of the first body 121 near the main body 11 in the second direction Y. This makes the first body 121 less prone to bending deformation in the second direction Y towards the main body 11, thereby improving the deformation resistance of the first body 121 and improving the structural stability of the power supply part 12.

[0083] In some embodiments, there are two fourth reinforcing parts 12c, and one end of each of the two fourth reinforcing parts 12c in the first direction X can be connected to one of the two second reinforcing parts 12b respectively.

[0084] In some embodiments, the fourth reinforcing part 12c and the first body 121 can be integrally formed, that is, the fourth reinforcing part 12c and the first body 121 can be formed by stamping or cutting a substrate plate, so that the fourth reinforcing part 12c can be recessed in the second direction Y relative to the surface of the first body 121 on the side away from the main body 11.

[0085] Figure 6 This is a rear view of antenna 1 according to some embodiments of this application.

[0086] like Figure 6As shown, in some embodiments, the third body 141 is connected to the main body 11 via a third bend 14a. A fifth reinforcing part 14b is provided on the third bend 14a. The fifth reinforcing part 14b extends from the main body 11 toward the third body 141 and protrudes from the surface of the third bend 14a toward the support part 14 and the main body 11. This makes it less likely for the support part 14 to bend or deform toward the main body 11, thus improving the deformation resistance of the third bend 14a. This also makes it less likely for the support part 14 and the main body 11 to bend or deform, thereby improving the structural stability of the antenna 1.

[0087] In some embodiments, the fifth reinforcing portion 14b, the third bending portion 14a, the main body portion 11, and the supporting portion 14 can be integrally formed, that is, the fifth reinforcing portion 14b, the third bending portion 14a, the main body portion 11, and the supporting portion 14 can be formed by cutting, stamping, or bending a substrate plate, such that the fifth reinforcing portion 14b is recessed on the surface of the third bending portion 14a away from the supporting portion 14 and the main body portion 11.

[0088] In some embodiments, the widths of the first reinforcing part 11a, the second reinforcing part 12b, the third reinforcing part 13b, the fourth reinforcing part 12c, and the fifth reinforcing part 14b may be the same to facilitate the fabrication of the antenna 1.

[0089] According to some embodiments of this application, this application also provides a remote information processor, which includes a circuit board 2 and the antenna 1 described in any of the foregoing embodiments.

[0090] In some embodiments, the telematics processor can be an in-vehicle T-BOX (Telematics-BOX). The in-vehicle T-BOX can act as a wireless gateway to provide a remote communication interface for the entire vehicle. The in-vehicle T-BOX can be mainly used to communicate with a mobile APP or the vehicle's back-end system to realize the display and control of vehicle information by the mobile APP.

[0091] like Figure 1 As shown, in some embodiments, the remote information processor further includes a 5G module 21, which can be disposed on the side of the circuit board 2 near the antenna 1 in the first direction X. In some embodiments, at least a portion of the orthographic projection of the antenna 1 in the first direction X overlaps with at least a portion of the orthographic projection of the 5G module 21 in the first direction X, thereby improving the compactness of the relative positions of the devices on the circuit board 2.
