Description

Technical Field

[0001] This utility model relates to the field of electronic technology, and in particular to a terminal device. Background Technology

[0002] LDS stands for Laser-Direct Structuring. An LDS antenna is an antenna manufactured using this technology. LDS antennas enable an integrated design of the antenna and its plastic housing, which is beneficial for the miniaturization and weight reduction trends in terminal devices.

[0003] However, the terminal devices in related technologies need to support antennas of various standards and frequency bands, and the overall environment is relatively complex. LDS antennas are difficult to obtain good clearance conditions and cannot achieve the expected performance, which limits the promotion and application of LDS antennas in terminal devices. Utility Model Content

[0004] This utility model provides a terminal device that can solve the problem that the overall environment of the terminal device is relatively complex, and the LDS antenna is difficult to obtain good clearance conditions, thus failing to achieve the expected performance.

[0005] The technical solution is as follows:

[0006] A terminal device, the terminal device comprising: a device body, a rear camera module, and an antenna assembly;

[0007] The rear camera module is located on the back of the device body;

[0008] The rear camera module includes a rear camera bracket and a rear camera cover plate. The rear camera bracket is connected to the device body, and the rear camera cover plate is located on the side of the rear camera bracket away from the device body.

[0009] The antenna assembly includes at least two LDS stubs and a three-dimensional feed stub;

[0010] The at least two LDS stubs are located on two adjacent sides of the rear camera bracket, and the at least two LDS stubs are interconnected; one end of the three-dimensional power supply stub is electrically connected to at least one of the at least two LDS stubs, and the other end of the three-dimensional power supply stub extends toward the side where the device body is located, and is at least partially located on the side of the rear camera bracket facing the device body.

[0011] In this embodiment, to address the issue of poor clearance conditions for LDS antennas, a rear camera bracket and a rear camera cover are arranged in the rear camera module on the back of the device body. The LDS antenna is then divided into at least two LDS stubs and one three-dimensional feed stub. The at least two LDS stubs are respectively arranged on two adjacent sides of the rear camera bracket and are interconnected to form a larger radiating stub. Compared to a single LDS stub, this radiating stub can have a larger conductive length. Moreover, since the sides of the rear camera bracket have different spatial positions, it is beneficial to optimize the radiation scene distribution and performance of the radiating stub, enabling the radiating stub to have omnidirectional radiation capability. The three-dimensional feed stub can realize the power supply connection between at least two LDS stubs and the device body, allowing the LDS antenna to receive power supply signals and realize the reception and transmission of wireless signals, thus enabling the application of LDS antennas in terminal devices.

[0012] In some possible implementations, the rear camera bracket includes a first side and a second side, the first side being parallel to the back of the device body and the second side being perpendicular to the back of the device body;

[0013] The number of LDS branches is two, one of which is located on the first side and the other is located on the second side.

[0014] With the above arrangement, one of the two LDS stubs is arranged on the first side of the rear camera bracket, and the other is arranged on the second side of the rear camera bracket. Since the first side and the second side are perpendicular to each other in space, the two LDS stubs are perpendicular to each other. This can enhance the omnidirectional radiation capability of the LDS antenna and optimize the antenna radiation pattern distribution and performance.

[0015] In some possible implementations, the antenna assembly further includes a first bending structure that is connected to each of the two LDS stubs.

[0016] In this embodiment, in order to connect the two LDS stubs together, a first bending structure is used to connect the two LDS stubs in series, so that the two LDS stubs have the same operating current, which satisfies the requirements for receiving and transmitting wireless signals.

[0017] In some possible implementations, the three-dimensional power supply stub includes a via structure located within the rear camera bracket and extending through the rear camera bracket in directions close to and away from the device body.

[0018] In this embodiment, the rear camera bracket is located on the back of the device body, and a rear camera cover is installed on the outside. The LDS antenna is fed three-dimensionally through a through-hole structure arranged inside the rear camera bracket, eliminating the need for additional conductive structures on the outside of the rear camera bracket and avoiding interference with the appearance of the rear camera module. Moreover, the rear camera bracket is usually an injection-molded structural component, and the through-hole structure can be integrally formed during the injection molding process, resulting in a simple structure and low production and processing costs.

[0019] In some possible implementations, the three-dimensional power supply branch further includes a metal conductive post located on the side of the rear camera bracket facing the device body, one end of the metal conductive post being electrically connected to the via structure, and the other end extending toward the device body.

[0020] With the above arrangement, since the rear camera bracket is located on the back of the device body, and the LDS antenna needs to be connected to the feed circuit inside the device body, but the rear camera bracket does not have a structure that extends into the device body, a metal conductive post in a protruding state is set on the side of the rear camera bracket as a bridging channel between the three-dimensional feed branch and the device body.

[0021] In some possible implementations, the three-dimensional power supply branch further includes a second bending structure, which is electrically connected to both the metal conductive post and the via structure.

[0022] Considering that the metal conductive post has a certain volume, it cannot be placed at any position on the rear camera bracket. It can only be placed in a position with sufficient volume and thickness in the rear camera bracket. However, this position may not correspond to the position of the via structure. Therefore, a second bending structure is arranged between the via structure and the metal conductive post to achieve electrical connection between the via structure and the metal conductive post.

[0023] In some possible implementations, the second bending structure includes at least one first bending portion and at least one second bending portion;

[0024] The at least one first bend is arranged in a direction parallel to the back of the device body, and the at least one second bend is arranged in a direction inclined to or perpendicular to the back of the device body.

[0025] With the above arrangement, the second bending structure can be bridged in three-dimensional space using at least one first bending part and at least one second bending part, thereby realizing the electrical connection between the through-hole structure and the metal conductive post.

[0026] In some possible implementations, the device body includes a main circuit board arranged parallel to the back of the device body;

[0027] The main circuit board is provided with a power feeding spring, which is electrically connected to the three-dimensional power feeding branch.

[0028] With the above arrangement, the main circuit board can be electrically connected to the three-dimensional feed branch using the feed spring, thereby realizing the feed connection between the LDS antenna and the main circuit board.

[0029] In some possible implementations, when the three-dimensional feed branch includes a metal conductive post, a second bending structure, and a via structure, the feed spring is electrically connected to the metal conductive post, the metal conductive post is electrically connected to the second bending structure, and the second bending structure is electrically connected to the at least two LDS branches through the via structure.

[0030] With the above arrangement, after the rear camera bracket is assembled in place, the position of the metal conductive post in the three-dimensional power supply branch is aligned with the position of the power supply spring, realizing contact electrical connection. The via structure is electrically connected to the metal conductive post through the second bending structure, and the LDS branch is connected to the via structure, realizing the electrical connection between the LDS branch and the main circuit board.

[0031] In some possible implementations, the extension dimension L1 of the three-dimensional power supply stub in a direction perpendicular to the back of the device body is 4.5-5.5 mm.

[0032] With the above arrangement, the three-dimensional feed stub can realize the feed connection of the LDS antenna over a large extension dimension, meeting the high span feed requirements of the LDS antenna. Attached Figure Description

[0049] Unless otherwise defined, all technical terms used in the embodiments of this utility model have the same meaning as commonly understood by those skilled in the art.

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0051] Combination Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a terminal device, which includes: a device body 1, a rear camera module 2, and an antenna assembly 3.

[0052] The rear camera module 2 is located on the back of the device body 1; the rear camera module 2 includes a rear camera bracket 21 and a rear camera cover plate 22. The rear camera bracket 21 is connected to the device body 1, and the rear camera cover plate 22 is located on the side of the rear camera bracket 21 away from the device body 1.

[0053] The antenna assembly 3 includes at least two LDS stubs 31 and a three-dimensional feed stub 32; the at least two LDS stubs 31 are respectively located on two adjacent sides of the rear camera bracket 21 and are interconnected; one end of the three-dimensional feed stub 32 is electrically connected to at least one of the at least two LDS stubs 31, and the other end of the three-dimensional feed stub 32 extends toward the side of the device body 1 and is at least partially located on the side of the rear camera bracket 21 toward the device body 1.

[0054] In this embodiment, to address the issue of poor clearance conditions for the LDS antenna, a rear camera bracket 21 and a rear camera cover 22 are arranged in the rear camera module 2 on the back of the device body 1. The LDS antenna is then divided into at least two LDS stubs 31 and a three-dimensional feed stub 32. The at least two LDS stubs 31 are respectively arranged on two adjacent sides of the rear camera bracket 21 and are interconnected to form a larger radiating stub. Compared to a single LDS stub 31, this radiating stub can have a larger conductive length. Moreover, since the sides of the rear camera bracket 21 have different spatial positions, it is beneficial to optimize the radiation scene distribution and performance of the radiating stub, enabling the radiating stub to have omnidirectional radiation capability. The three-dimensional feed stub 32 can realize the feed connection between at least two LDS stubs 31 and the device body 1, allowing the LDS antenna to receive feed signals and realize the reception and transmission of wireless signals, thus enabling the application of the LDS antenna in the terminal device.

[0055] In related technologies, due to the large size of the camera in the rear camera module 2, the area of ​​the rear camera bracket 21 is relatively narrow. On the one hand, there is not a large enough plane to use LDS process for etching, and on the other hand, the LDS branches 31 that can be etched are generally small, which is insufficient to realize the reception and transmission of wireless signals.

[0056] Therefore, this embodiment adopts a three-dimensional spatial routing method, etching LDS branches 31 on adjacent sides respectively, and finally connecting at least two LDS branches 31 together for use.

[0057] In some possible implementations, the rear camera bracket 21 is injection molded from a modified plastic containing a special metal oxide (such as a copper or nickel compound), such as PC (polycarbonate), LCP (liquid crystal polymer), and ABS (acrylonitrile-butadiene-styrene copolymer).

[0058] The corresponding side of the rear camera bracket 21 is irradiated with a laser to decompose and reduce the metal oxide into metal particles (such as copper particles), forming a rough microstructure. After chemical plating, conductive circuits are formed on the side of the rear camera bracket 21. These conductive circuits are the LDS stubs 31 mentioned above.

[0059] Combination Figure 3 and Figure 4 As shown, in some possible implementations, the rear camera bracket 21 includes a first side 211 and a second side 212. The first side 211 is parallel to the back of the device body 1, and the second side 212 is perpendicular to the back of the device body 1. The number of LDS branches 31 is two, with one LDS branch 31 located on the first side 211 and the other LDS branch 31 located on the second side 212.

[0060] With the above arrangement, one of the two LDS stubs 31 is arranged on the first side 211 of the rear camera bracket 21, and the other is arranged on the second side 212 of the rear camera bracket 21. Since the first side 211 and the second side 212 are perpendicular to each other in space, the two LDS stubs 31 are perpendicular to each other. This can enhance the omnidirectional radiation capability of the LDS antenna and optimize the antenna radiation pattern distribution and performance.

[0061] Combination Figure 3 As shown, in some possible implementations, the antenna assembly 3 further includes a first bending structure 33, which is connected to two LDS stubs 31 respectively.

[0062] In this embodiment, in order to connect the two LDS stubs 31 together, a first bending structure is used to connect the two LDS stubs 31, so that the two LDS stubs 31 have the same operating current, which satisfies the requirements for receiving and transmitting wireless signals.

[0063] Combination Figure 3 and Figure 5 As shown, in some possible embodiments, the three-dimensional power supply stub 32 includes a via structure 321 located within the rear camera bracket 21 and extending through the rear camera bracket 21 in directions close to and away from the device body 1.

[0064] In this embodiment, the rear camera bracket 21 is arranged on the back of the device body 1, and a rear camera cover plate 22 is installed on the outside. The LDS antenna is fed in three dimensions through the through-hole structure 321 arranged inside the rear camera bracket 21. There is no need to arrange additional conductive structures on the outside of the rear camera bracket 21, and it will not interfere with the appearance of the rear camera module 2. Moreover, the rear camera bracket 21 is usually an injection molded structural part, and the through-hole structure 321 can be integrally formed during the injection molding process, which is simple in structure and has low production and processing costs.

[0065] Combination Figure 3 and Figure 5 As shown, in some possible embodiments, the three-dimensional power supply branch 32 also includes a metal conductive post 322, which is located on the side of the rear camera bracket 21 facing the device body 1. One end of the metal conductive post 322 is electrically connected to the via structure 321, and the other end extends toward the device body.

[0066] With the above arrangement, since the rear camera bracket 21 is arranged on the back of the device body 1, and the LDS antenna needs to be connected to the internal circuit of the device body 1, but the rear camera bracket 21 does not extend into the structure of the device body 1, a metal conductive post 322 in a protruding state is provided on the side of the rear camera bracket 21 as a bridging channel between the three-dimensional feed branch 32 and the device body 1.

[0067] Combination Figure 5 As shown, in some possible embodiments, the three-dimensional power supply branch 32 further includes a second bending structure 323, which is electrically connected to the metal conductive post 322 and the via structure 321, respectively.

[0068] Considering that the metal conductive post 322 has a certain volume, it cannot be arbitrarily placed at any position in the rear camera bracket 21. It can only be placed in a position in the rear camera bracket 21 with sufficient volume and thickness. However, this position may not correspond to the position of the via structure 321. Therefore, a second bending structure 323 is arranged between the via structure 321 and the metal conductive post 322 to achieve electrical connection between the via structure 321 and the metal conductive post 322.

[0069] Combination Figure 5 As shown, in some possible embodiments, the second bending structure 323 includes at least one first bending portion 3231 and at least one second bending portion 3232; at least one first bending portion 3231 is arranged in a direction parallel to the back of the device body 1, and at least one second bending portion 3232 is arranged in a direction inclined to or perpendicular to the back of the device body 1.

[0070] With the above arrangement, the second bending structure 323 can be bridged in three-dimensional space by using at least one first bending portion 3231 and at least one second bending portion 3232 to realize the electrical connection between the through hole structure 321 and the metal conductive post 322.

[0071] For example, at least one first bend 3231 and at least one second bend 3232 are arranged alternately.

[0072] Combination Figure 5 As shown, in some possible embodiments, the device body 1 includes a main circuit board 11, which is arranged parallel to the back of the device body 1; the main circuit board 11 is provided with a power feeding spring 111, which is electrically connected to the three-dimensional power feeding branch 32.

[0073] With the above arrangement, the main circuit board 11 can be electrically connected to the three-dimensional feeding branch 32 by using the feeding spring 111, so as to realize the feeding connection between the LDS antenna and the main circuit board 11.

[0074] The LDS antenna and the main circuit board 11 are connected by a power supply without soldering. After the rear camera bracket 21 is assembled, the position of the three-dimensional power supply branch 32 is aligned with the position of the power supply spring 111 to achieve contact power connection.

[0075] Combination Figure 5As shown, in some possible embodiments, when the three-dimensional feed branch 32 includes a metal conductive post 322, a second bending structure 323 and a via structure 321, the feed spring 111 is electrically connected to the metal conductive post 322, the metal conductive post 322 is electrically connected to the second bending structure 323, and the second bending structure 323 is electrically connected to at least two LDS branches 31 through the via structure 321.

[0076] With the above arrangement, after the rear camera bracket 21 is assembled, the position of the metal conductive post 322 in the three-dimensional power supply branch 32 is aligned with the position of the power supply spring 111 to achieve contact electrical connection. The via structure 321 is electrically connected to the metal conductive post 322 through the second bending structure 323, and the LDS branch 31 is connected to the via structure 321 to achieve electrical connection between the LDS branch 31 and the main circuit board 11.

[0077] In this embodiment, the distance between the rear camera bracket 21 and the main circuit board 11 reaches 5.7mm, which is much greater than the height of the power feeding spring 111 (0.7mm), which poses a power feeding difficulty problem. Therefore, the second bending structure 323, in conjunction with the metal conductive post 322, can compensate for the distance in the thickness direction of the device body 1 (i.e., the direction perpendicular to the back of the device body 1), and realize the electrical connection between the through-hole structure 321 on the main circuit board 11 and the rear camera bracket 21.

[0078] Combination Figure 5 As shown, in some possible embodiments, the extension dimension L1 of the three-dimensional power supply branch 32 in the direction perpendicular to the back of the device body 1 is 4.5-5.5 mm.

[0079] With the above arrangement, the three-dimensional feed stub 32 can realize the feed connection of the LDS antenna over a large extension size, meeting the high span feed requirements of the LDS antenna.

[0080] In some possible implementations, LDS antennas are used to cover the GPS L5 band. The GPS L5 band is a newly added civilian signal band in the modern Global Positioning System (GPS), designed to improve navigation accuracy, reliability, and anti-interference capabilities, especially in complex environments (such as urban canyons and forests). Using LDS antennas to cover the GPS L5 band provides omnidirectional radiation capability and a better antenna radiation pattern distribution, which is beneficial for improving the communication capabilities of terminal devices in the GPS L5 band.

[0081] In some possible implementations, the terminal device can be any of a variety of computer system devices that are mobile or portable and perform wireless communication. Specifically, the terminal device can be a mobile phone or smartphone (e.g., an iPhone™-based phone, an Android™-based phone), a portable gaming device (e.g., a Nintendo DS™, a PlayStation Portable™, a Gameboy Advance™, an iPhone™), a laptop computer, a PDA, a portable internet device, a music player, and a data storage device, other handheld devices, and devices such as headphones. The terminal device can also be other wearable devices that require charging (e.g., head-mounted devices (HMDs) such as electronic bracelets, electronic necklaces, terminal devices, or smartwatches).

[0082] The terminal device can also be any one of multiple terminal devices, including but not limited to cellular phones, smartphones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transport instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbooks, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Image Experts Group (MPEG-1 or MPEGG-2) audio layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0083] In some cases, a terminal device can perform multiple functions (e.g., playing music, displaying video, storing pictures, and receiving and sending telephone calls). If desired, the terminal device can be such as a cellular phone, media player, other handheld device, wristwatch, pendant device, handset device, or other compact portable device.
