Description

Technical Field

[0001] This utility model relates to the field of communication technology, specifically to a communication system between a mobile terminal and an external module, a mobile terminal, and an external module. Background Technology

[0002] With the continuous development of technology, the integration level of mobile terminals (such as mobile phones and tablets) is becoming increasingly higher, constantly pursuing thinner and smaller bodies. Therefore, limited by internal space and battery capacity, many modules within mobile terminals cannot reach the performance level of professional equipment. For example, the camera function; the sensor module and lens module of a professional camera are difficult to integrate into existing mobile phones and tablets. This results in limited camera performance on mobile terminals. For photography enthusiasts, owning a mobile phone is not enough; they still need to purchase and carry a dedicated professional camera to achieve the desired shooting results.

[0003] To address these issues, many mobile devices have begun to support external specialized modules to achieve corresponding functions. For example, they support the magnetic attachment of an external lens to the phone's casing to enhance its photography capabilities. This necessitates the use of high-speed transmission interfaces to achieve data transmission between the external module and the mobile terminal. Existing technologies mostly employ methods such as... Figure 1 The optical module communication scheme shown is used to achieve this. However, although the optical module communication scheme can achieve high-speed communication bandwidth between the external module and the mobile terminal, it has problems such as high cost, high power consumption, high heat generation, large size, and easy obstruction of the optical path, which affects communication. In addition, it requires the backplane of the mobile terminal and the external module to have holes at the location of the optical module to provide an optical signal path. This not only increases the manufacturing difficulty, but also, because it destroys the integrity of the backplane, it will be detrimental to the waterproof and dustproof design.

[0059] Please refer to Figure 2 Embodiment 1 of this utility model is as follows:

[0060] This embodiment provides a communication system between a mobile terminal and an external module, including a first millimeter-wave transceiver module A1 and a second millimeter-wave transceiver module B1; the first millimeter-wave transceiver module A1 is fixedly disposed inside the housing of the mobile terminal A; the second millimeter-wave transceiver module B1 is fixedly disposed inside the housing of the external module B; after the external module B is detachably assembled to a designated position on the housing of the mobile terminal A, the positions of the first millimeter-wave transceiver module A1 and the second millimeter-wave transceiver module B1 correspond to each other.

[0061] The mobile terminal A can be an electronic device with mobility, convenience, and interactive functions, such as a mobile phone, laptop, tablet, or smartwatch.

[0062] The external module B refers to an independent component module with specific functions that can be detachably assembled onto a mobile terminal to expand or enhance the functionality of the mobile terminal. In this document, the external module may be an external camera, external speaker, game controller, external POS machine, external medical sensor, etc.

[0063] The first millimeter-wave transceiver module A1 is located inside the mobile terminal A, near the inner wall of the mobile terminal's casing A2. The first millimeter-wave transceiver module A1 is used to establish a wireless communication connection with the second millimeter-wave transceiver module B1 in the external module B based on millimeter-wave wireless communication technology, and to establish a wired connection with the central processing unit A3 of the mobile terminal A. Specifically, the first millimeter-wave transceiver module supports full-duplex wireless communication, capable of converting instructions issued by the mobile terminal's central processing unit into millimeter-wave wireless signals and transmitting them, and receiving millimeter-wave wireless signals sent by the external module through the second millimeter-wave transceiver module, converting them into corresponding high-speed digital signals, and transmitting them to the central processing unit.

[0064] The second millimeter-wave transceiver module B1 is located inside the external module B, near the inner wall of the outer casing B2 of the external module. Specifically, it is the inner wall of the end face of the outer casing of the external module B that fits against the mobile terminal after the external module B is assembled onto the mobile terminal A. The second millimeter-wave transceiver module is used to establish a wireless communication connection with the first millimeter-wave transceiver module in the mobile terminal based on millimeter-wave wireless communication technology, and to establish a wired connection with the signal processing module of the external module. Specifically, the second millimeter-wave transceiver module also supports full-duplex wireless communication, capable of converting high-speed digital signals emitted by the signal processing module of the external module into corresponding millimeter-wave wireless signals for transmission, and receiving millimeter-wave wireless signals transmitted by the mobile terminal through the first millimeter-wave transceiver module, converting them back into corresponding high-speed digital signals, and transmitting them to the signal processing module.

[0065] The communication system provided in this embodiment, when the external module is detachably assembled onto the housing of the mobile terminal, has a first millimeter-wave transceiver module located inside the mobile terminal corresponding to a second millimeter-wave transceiver module located inside the external module. The two modules can establish a wireless communication connection based on millimeter-wave wireless communication technology, thereby achieving high-speed data communication between the mobile terminal and the external module. On one hand, because millimeter-wave wireless communication technology has very high data bandwidth, it can easily achieve communication rates of over 10Gbps, thus ensuring that data transmission between the mobile terminal and the external module meets low-latency requirements. On the other hand, millimeter waves have strong penetrating power, enabling high-speed data transmission while maintaining the integrity of the housing of both the mobile terminal and the external module. This not only reduces processing difficulty (no need for drilling holes and adding glass) but also provides strong tolerance to housing wear and dirt, making it more conducive to waterproof and dustproof design.

[0066] Please see Figure 3 and Figure 4 The second embodiment provided in this embodiment is as follows:

[0067] This embodiment is a further extension of Embodiment 1, and specifically describes the structure of the first millimeter-wave transceiver module and the second millimeter-wave transceiver module.

[0068] The communication system between the mobile terminal and the external module provided in this embodiment, such as Figure 3 As shown, the first millimeter-wave transceiver module A1 includes a first millimeter-wave antenna A11 and a first millimeter-wave transceiver circuit A12; the first millimeter-wave transceiver circuit A12 is connected to the first millimeter-wave antenna A11 and the central processing unit A3 of the mobile terminal A, respectively.

[0069] The second millimeter-wave transceiver module B1 includes a second millimeter-wave antenna B11 and a second millimeter-wave transceiver circuit B12; the second millimeter-wave transceiver circuit B12 is connected to the second millimeter-wave antenna B11 and the signal processing module B3 of the external module B, respectively.

[0070] The first millimeter-wave antenna A11 is used to transmit the millimeter-wave signal sent by the first millimeter-wave transceiver circuit, and to receive the millimeter-wave signal sent by the second millimeter-wave antenna and transmit it to the first millimeter-wave transceiver circuit.

[0071] Similarly, the second millimeter-wave antenna B11 is used to transmit the millimeter-wave signal sent by the second millimeter-wave transceiver circuit, and to receive the millimeter-wave signal sent by the first millimeter-wave antenna and transmit it to the second millimeter-wave transceiver circuit.

[0072] The first millimeter-wave transceiver circuit A12 is used to convert control commands issued by the central processing unit into millimeter-wave wireless signals and send them to the first millimeter-wave antenna, and to convert the millimeter-wave wireless signals sent from the first millimeter-wave antenna into corresponding high-speed digital signals and send them to the central processing unit.

[0073] Similarly, the second millimeter-wave transceiver circuit B12 is used to convert the high-speed digital signal emitted by the signal processing module into a corresponding millimeter-wave wireless signal and send it to the second millimeter-wave antenna, and to convert the millimeter-wave wireless signal sent from the second millimeter-wave antenna into a corresponding control command and send it to the signal processing module.

[0074] In some specific implementations of this embodiment, such as Figure 3 As shown, the first millimeter-wave transceiver circuit A12 includes a first millimeter-wave receiving circuit A12-RX and a first millimeter-wave transmitting circuit A12-TX, and has full-duplex communication capabilities. The first millimeter-wave receiving circuit A12-RX and the first millimeter-wave transmitting circuit A12-TX are respectively connected to the central processing unit A3 and also respectively connected to the first millimeter-wave antenna A11.

[0075] Among them, such as Figure 4 As shown, the first millimeter-wave transmitting circuit A12-TX includes a first oscillator, a first modulator, and a first power amplifier connected in sequence; the output terminal of the first power amplifier is connected to the first millimeter-wave antenna A11. Optionally, the output terminal of the first power amplifier can also be connected to the first millimeter-wave antenna through a first matched output network.

[0076] Here, the first millimeter-wave transmitting circuit is used to convert the control commands issued by the central processing unit into millimeter-wave wireless signals and then transmit them to the first millimeter-wave antenna. Its working principle is as follows:

[0077] The first oscillator generates a carrier signal of a specified frequency and inputs it to the first modulator. The control command issued by the central processing unit of the mobile terminal arrives at the first modulator as an input signal. The first modulator modulates the carrier signal and the input signal into a first mixed signal and sends it to the first power amplifier. The first power amplifier amplifies the received first mixed signal and sends it to the first millimeter-wave antenna, which then transmits it.

[0078] The first millimeter-wave receiving circuit A12-RX includes a first low-noise amplifier and a first envelope detector connected together; the input terminal of the first low-noise amplifier is connected to the first millimeter-wave antenna A11.

[0079] Here, the first millimeter-wave receiving circuit is used to receive the millimeter-wave wireless signal emitted by the second millimeter-wave antenna, convert it into a corresponding high-speed digital signal, and then send it to the central processing unit of the mobile terminal. Its working principle is as follows:

[0080] After receiving the millimeter-wave signal from the external module, the first millimeter-wave antenna transmits it to the first low-noise amplifier, which amplifies and reduces the noise before sending it to the first envelope detector. The first envelope detector demodulates the signal to obtain the corresponding high-speed digital signal, which is then sent to the central processing unit.

[0081] In some other specific embodiments of this example, such as Figure 3 As shown, the second millimeter-wave transceiver circuit B12 includes both a second millimeter-wave receiving circuit B12-RX and a second millimeter-wave transmitting circuit B12-TX, and also possesses full-duplex communication capabilities. The second millimeter-wave receiving circuit B12-RX and the second millimeter-wave transmitting circuit B12-TX are respectively connected to the signal processing module B3 and also respectively connected to the second millimeter-wave antenna B11.

[0082] Among them, such as Figure 4 As shown, the second millimeter-wave transmitting circuit B12-TX includes a second oscillator, a second modulator, and a second power amplifier connected in sequence; the output terminal of the second power amplifier is connected to the second millimeter-wave antenna. Optionally, the output terminal of the second power amplifier can also be connected to the second millimeter-wave antenna through a second matching output network.

[0083] Here, the second millimeter-wave transmitting circuit is used to convert the high-speed digital signal emitted by the signal processing module of the external module into a corresponding millimeter-wave wireless signal and then transmit it to the second millimeter-wave antenna. Its working principle is as follows:

[0084] The second oscillator generates a carrier signal of a specified frequency and inputs it to the second modulator. The high-speed digital signal emitted by the signal processing module of the external module is used as the input signal and arrives at the second modulator. The second modulator modulates the carrier signal and the input signal into a second mixed signal and sends it to the second power amplifier. The second power amplifier amplifies the received second mixed signal and sends it to the second millimeter-wave antenna, which then transmits it.

[0085] The second millimeter-wave receiving circuit B12-RX includes a second low-noise amplifier and a second envelope detector connected in series; the input terminal of the second low-noise amplifier is connected to the second millimeter-wave antenna.

[0086] Here, the second millimeter-wave receiving circuit is used to receive the millimeter-wave wireless signal emitted by the first millimeter-wave antenna, convert it into a corresponding high-speed digital signal, and then send it to the signal processing module of the external module. Its working principle is as follows:

[0087] After receiving the millimeter-wave signal from the mobile terminal, the second millimeter-wave antenna transmits it to the second low-noise amplifier, which amplifies and reduces the noise before sending it to the second envelope detector. The second envelope detector demodulates the signal to obtain the corresponding control command and then sends it to the signal processing module.

[0088] As can be seen from the above, a two-way high-speed wireless communication link can be established between the first millimeter-wave transceiver module of the mobile terminal and the second millimeter-wave transceiver module of the external module based on millimeter-wave wireless communication technology; thereby realizing full-duplex communication interaction between the mobile terminal and the external module.

[0089] Specifically, such as Figure 3 As shown, the central processing unit A3, the first millimeter-wave transmitting circuit A12-TX, and the first millimeter-wave antenna A11 in the mobile terminal, and the second millimeter-wave antenna B11, the second millimeter-wave receiving circuit B12-RX, and the signal processing module B3 in the external module constitute a high-speed wireless communication link from the mobile terminal to the external module; the second millimeter-wave transmitting circuit B12-TX and the second millimeter-wave antenna B11 in the external module, and the first millimeter-wave antenna A11, the first millimeter-wave receiving circuit A12-RX, and the central processing unit A3 in the mobile terminal constitute a high-speed wireless communication link from the external module to the mobile terminal.

[0090] In some specific embodiments of this example, both the first millimeter-wave transceiver module and the second millimeter-wave transceiver module are full-duplex millimeter-wave transceiver chips; the first millimeter-wave antenna and the second millimeter-wave antenna are full-duplex antennas. Optionally, the full-duplex antenna can be a single antenna capable of full-duplex communication, or it can be an antenna combination. Optionally, the first millimeter-wave transceiver module and the second millimeter-wave transceiver module can use identical full-duplex millimeter-wave transceiver chips to achieve chip reuse; alternatively, they can use full-duplex millimeter-wave transceiver chips of different frequencies, in conjunction with full-duplex antennas of different frequencies, to suppress full-duplex crosstalk in the millimeter-wave band and obtain better communication quality.

[0091] Please see Figure 5 The third embodiment provided in this example is as follows:

[0092] This embodiment further extends any of the above embodiments to provide a mobile terminal. The mobile terminal includes, but is not limited to, mobile phones, laptops, tablets, and smartwatches.

[0093] like Figure 5 As shown, the mobile terminal A in this embodiment includes a housing A2, a central processing unit A3, and a first millimeter-wave transceiver module A1 as described in any of the above embodiments. The specific structure of the first millimeter-wave transceiver module A1 and its specific location within the mobile terminal will not be described again here; please refer to the descriptions in the above embodiments for details.

[0094] In this embodiment, the central processing unit A3 includes a processing unit A31 and a control unit A32; the input terminal of the first millimeter-wave transceiver module A1 is connected to the control unit A32, and the output terminal is connected to the processing unit A31.

[0095] The control unit is used to generate corresponding control commands based on the user's operation on the mobile terminal and send them to the first millimeter-wave transceiver module so as to transmit them wirelessly to the external module via millimeter waves.

[0096] The processing unit is used to receive high-speed digital signals sent from the first millimeter-wave transceiver module (of the external module) and convert them into data required by the user, such as camera data and audio data.

[0097] As described above, the mobile terminal provided in this embodiment is equipped with a first millimeter-wave transceiver module. When the external module is detachably assembled onto its housing, the first millimeter-wave transceiver module can establish a wireless communication connection with the second millimeter-wave transceiver module of the external module based on millimeter-wave wireless communication technology, thereby realizing high-speed data communication between the mobile terminal and the external module. Compared with the prior art method of using optical modules for wireless communication between the mobile terminal and the external module, the high-speed wireless communication between the mobile terminal and the external module provided in this embodiment using millimeter-wave wireless communication technology can easily achieve communication rates of over 10Gbps, ensuring that data transmission between the mobile terminal and the external module meets low latency requirements. Moreover, it eliminates the need for opening holes in the housings of the mobile terminal and the external module, reducing processing difficulty and manufacturing costs, and also facilitating waterproof and dustproof design.

[0098] In some specific embodiments of this example, the optional placement positions of the first millimeter-wave transceiver module include, but are not limited to: the rear cover position (i.e., the back shell position), the upper end face position (i.e., the top shell position), the lower end face position (i.e., the bottom shell position), and the side end face positions of the mobile terminal housing. In short, any position other than the display screen area. Because the first millimeter-wave transceiver module inside the mobile terminal and the second millimeter-wave transceiver module in the external module need to correspond in position during use to ensure the stability of data transmission and reception, the placement position of the first millimeter-wave transceiver module is determined by the assembly position of the external module; and the assembly position of the external module can be considered comprehensively based on factors such as the size, stability, convenience, and signal interference of the external module.

[0099] In a preferred embodiment, the smart terminal is a mobile phone, and the external module is an external camera. Assembling an external camera on the mobile phone enhances the photographic effect. The first millimeter-wave transceiver module is fixedly installed inside the back cover of the mobile phone, such as near the center of the back cover.

[0100] In another preferred embodiment, the smart terminal is a laptop computer, and the external module is an external speaker. Assembling an external speaker on the laptop computer can improve sound quality and enhance the audio experience. The first millimeter transceiver module is fixedly installed inside the back of the laptop's flip cover. For smooth flipping, it is preferably located near the top of the back of the flip cover; however, it can also be fixedly installed on the side of the laptop's flip cover or base.

[0101] In some specific embodiments of this example, the detachable assembly method between the mobile terminal and the external module can be selected from magnetic adsorption, snap-fit, clip, threaded connection, etc. Magnetic adsorption is preferred; that is, when needed, the external module can be magnetically attached to the mobile terminal's housing and easily detached at any time. Using magnetic adsorption ensures the integrity of both the mobile terminal and external module's housings, eliminating the need for destructive designs such as opening holes or creating grooves, and is also more conducive to dust and water resistance.

[0102] As a preferred embodiment, such as Figure 5 As shown, the first millimeter-wave transceiver module A1 is fixedly disposed inside the rear cover A21 of the housing A2 of the mobile terminal; at the same time, the rear cover A21 is also provided with a first magnetic component A4. The first magnetic component A4 can magnetically attract the external module B and limit and fix the external module B so that the first millimeter-wave transceiver module A1 and the second millimeter-wave transceiver module B1 inside the external module B correspond in position.

[0103] Furthermore, to ensure that millimeter-wave wireless transmission is not affected, the mobile terminal's casing is made of non-metallic material; correspondingly, the casing of the external module used in conjunction with the mobile terminal is also made of non-metallic material. In this case, a second magnetic component will be provided on the external module, which can attract each other with the first magnetic component on the mobile terminal, thereby ensuring that the mobile terminal and the external module are connected in a detachable manner.

[0104] Furthermore, to ensure sufficient magnetic attraction between the mobile terminal and the external module, preventing the external module from detaching during use, optionally, multiple first magnetic components are used; these multiple first magnetic components surround the first millimeter-wave transceiver module and are spaced apart circumferentially. Optionally, the first magnetic component is a ring-shaped magnetic component, with the ring-shaped magnetic component encircling the first millimeter-wave transceiver module. It is understood that the design of the first magnetic component surrounding the first millimeter-wave transceiver module is more conducive to the rapid positioning and assembly of the external module onto the mobile terminal, while ensuring the alignment of the first and second millimeter-wave transceiver modules.

[0105] Furthermore, the first magnetic component can be attached to the inner surface of the back cover of the mobile terminal housing to maintain the flatness of the outer surface of the mobile terminal housing and provide stronger anti-fouling performance. Alternatively, the first magnetic component can be attached to the outer surface of the back cover of the mobile terminal housing. Preferably, a receiving groove adapted to the first magnetic component is formed on the outer surface of the back cover to maintain the flatness of the back cover surface as much as possible. In addition, for small mobile terminals (such as mobile phones), the first magnetic component can also be sheet-shaped (such as a circular ring, rectangular piece, etc.), with one end fixedly connected to the back cover of the mobile terminal, and the other end can be folded outward at a certain angle with the fixed end as a fulcrum. In this way, the first magnetic component can function as a small mobile terminal, such as a mobile phone stand, without the external module being assembled.

[0106] Please see Figure 5 and Figure 6 The fourth embodiment provided in this example is as follows:

[0107] This embodiment further extends any of the above embodiments to provide an external module. The external module includes, but is not limited to, an external camera, external speakers, a game controller, an external POS machine, and an external medical sensor.

[0108] The external module provided in this embodiment, such as Figure 5 As shown, the module specifically includes a housing B2 of the external module, a signal processing module B3, and a second millimeter-wave transceiver module B1 according to any of the above embodiments; the second millimeter-wave transceiver module B1 is connected to the signal processing module B3. The specific structure of the second millimeter-wave transceiver module and its specific location within the external module will not be described in detail here; please refer to the description in the above embodiments for further details.

[0109] In some specific implementations, such as Figure 5 As shown, the external module B further includes a control module B5 and an execution module B6; the output terminal of the signal processing module B3 is connected to the control module B5, and its input terminal is connected to the execution module B6; the output terminal of the control module B5 is connected to the input terminal of the execution module B6.

[0110] The signal processing module is used to convert the high-speed digital signal sent by the second millimeter-wave transceiver module into corresponding control commands and send them to the control module, and to encode the data sent by the execution module and send it to the second millimeter-wave transceiver module for transmission.

[0111] The control module is used to control the execution module according to the control instructions sent by the signal processing module.

[0112] The execution module is used to perform corresponding operations under the control of the control module and transmit the data obtained from the operations to the signal processing module.

[0113] In some further embodiments, the external module also includes a battery module; the battery module is connected to the second millimeter-wave transceiver module, the signal processing module, and the execution module, respectively. The external module is powered by its own battery module, eliminating the need for external power. Optionally, the battery module can be a disposable battery or a rechargeable battery. If the latter, the external module's housing is also equipped with a corresponding charging interface.

[0114] As described above, the external module provided in this embodiment is equipped with a second millimeter-wave transceiver module. When the external module is detachably assembled onto the housing of the mobile terminal, its second millimeter-wave transceiver module can establish a wireless communication connection with the second millimeter-wave transceiver module of the mobile terminal based on millimeter-wave wireless communication technology, thereby realizing high-speed data communication between the mobile terminal and the external module. Compared with the prior art method of using optical modules for wireless communication between the mobile terminal and the external module, the external module provided in this embodiment uses millimeter-wave wireless communication technology to achieve high-speed wireless communication between the mobile terminal and the mobile terminal. This not only easily achieves communication rates of over 10Gbps, ensuring that data transmission between the mobile terminal and the external module meets low latency requirements, but also eliminates the need for opening holes in the housing of the mobile terminal and the external module, reducing processing difficulty and manufacturing costs, while also being more conducive to waterproof and dustproof design.

[0115] In some specific implementations of this embodiment, such as Figure 5 As shown, the second millimeter-wave transceiver module B1 is disposed on the inner surface of the housing B2 of the external module, specifically on the bonding surface after the external module is assembled onto the mobile terminal. If the external module is an external camera, its bonding surface is the non-lens mounting surface of the external camera, preferably the back side of the lens mounting surface.

[0116] In some specific embodiments of this example, the detachable assembly method between the external module and the mobile terminal can be selected from magnetic adsorption, snap-fit, clip, threaded connection, etc. Magnetic adsorption is preferred; that is, the external module is fixedly assembled to the mobile terminal's housing via magnetic adsorption and can be easily detached at any time. Using magnetic adsorption, the housing of the external module can remain intact, eliminating the need for destructive designs such as opening holes or slotting, and is also more conducive to dust and water resistance.

[0117] As a preferred embodiment, such as Figure 5As shown, the outer module's housing B2 has a second magnetic element B4 on its surface, and the second magnetic element B4 is located on the same side as the second millimeter-wave transceiver module B1 in the outer module B. The second magnetic element B4 enables the outer module B to be magnetically attached to the mobile terminal's housing A2, and makes the second millimeter-wave transceiver module B1 and the first millimeter-wave transceiver module A1 in the mobile terminal A correspond in position.

[0118] Furthermore, to ensure sufficient magnetic attraction between the mobile terminal and the external module, preventing the external module from detaching during use, optionally, multiple second magnetic components are used; these multiple second magnetic components surround the second millimeter-wave transceiver module and are spaced apart circumferentially. Optionally, the second magnetic component is a ring-shaped magnetic component, with the ring-shaped magnetic component encircling the second millimeter-wave transceiver module. It is understood that the design of the second magnetic component surrounding the second millimeter-wave transceiver module facilitates rapid positioning and assembly of the external module onto the mobile terminal, while ensuring alignment between the second and first millimeter-wave transceiver modules.

[0119] In some other specific embodiments of this example, such as Figure 6 As shown, the external module B is an external camera, and its internal execution module B6 is a sensor module. Correspondingly, the processing unit A31 in the mobile terminal A is an image processing unit. The sensor module includes an image sensor and lens mechanism, and other related components, capable of converting light signals into electrical signals and processing them to generate image data. Here, by using an external camera, the mobile terminal can acquire higher-quality photographic images, improving the mobile terminal's camera performance.

[0120] When external module B is an external camera, its signal processing module B3 is used to recover the high-speed digital signal sent from the second millimeter-wave transceiver module B1 into user commands and send them to the control module B5; and to receive the MIPI signal transmitted from the sensor module, convert it into a serial code stream and send it to the second millimeter-wave transceiver module B1, which then sends it to the mobile terminal A; the control module B5 of external module B is used to drive the sensor module to perform related actions according to the received user commands, such as focusing, taking pictures, and recording videos.

[0121] Please see Figure 5 The fifth embodiment provided in this example is as follows:

[0122] This embodiment further extends any of the above embodiments to provide a mobile terminal A, such as... Figure 5As shown, the device includes a housing A2 of a mobile terminal, an external module B detachably assembled to the housing A2 of the mobile terminal, and a communication system between the mobile terminal and the external module. The external module B is assembled to a designated position on the housing A2 of the mobile terminal by magnetic adsorption, so that the first millimeter-wave transceiver module A1 in the mobile terminal A corresponds to the second millimeter-wave transceiver module B1 in the external module B.

[0123] The mobile terminal in this embodiment is described in the above embodiment three, and will not be repeated here.

[0124] The external modules in this embodiment are described in detail in Embodiment 4 above, and will not be repeated here.

[0125] The communication system between the mobile terminal and the external module in this embodiment is described in detail in Embodiments 1 and 2 above, and will not be repeated here.

[0126] The mobile terminal provided in this embodiment is equipped with an external module and a dedicated communication system for wireless communication between the two. When the external module is detachably assembled onto the housing of the mobile terminal, the first millimeter-wave transceiver module inside the mobile terminal corresponds to the second millimeter-wave transceiver module inside the external module. The two can establish a wireless communication connection based on millimeter-wave wireless communication technology, thereby realizing high-speed data communication between the mobile terminal and the external module. On the one hand, since millimeter-wave wireless communication technology has a very high data bandwidth, it can easily achieve communication rates of over 10Gbps, thus ensuring that data transmission between the mobile terminal and the external module meets low latency requirements. On the other hand, millimeter waves have strong penetrating power, enabling high-speed data transmission while keeping the housings of the mobile terminal and the external module intact. This not only reduces processing difficulty (no need for drilling holes and adding glass), but also has strong tolerance to housing wear and dirt, making it more conducive to waterproof and dustproof design.

[0127] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
