Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and in particular to a vehicle-mounted bracket for a mobile terminal. Background Art

[0002] With the development of science and technology, mobile terminals (such as mobile phones, tablet computers and other electronic devices) are frequently used in people's lives, which can bring great convenience to people.

[0003] In order to provide convenience, some bracket devices are provided in the prior art to support mobile devices in some scenarios. For example, some desktop brackets are provided in the prior art, which can fix the support angle of mobile phones, tablets and other devices relative to the desktop, so that users can place the mobile devices on the relevant brackets to free their hands for viewing. Some vehicle brackets can also facilitate users to fix mobile terminals on vehicles so as to use mobile devices for navigation.

[0004] This type of bracket that only has a supporting function cannot meet the needs of users when used as a vehicle bracket. As mentioned above, many times users will use a bracket device to connect the mobile terminal to the vehicle, and then use the mobile terminal for navigation. During the navigation process, the user needs to use the traffic of the mobile terminal itself to connect to the network. However, when the terminal user is moving, sometimes there will be a situation where they cross from one service area to another. In this case, the physical SIM card of the mobile device itself may not be able to adapt to the use in different regions, or wireless roaming may occur during use. Therefore, if you only rely on the physical SIM card of the mobile terminal itself to connect to the Internet during driving, it is very likely that when switching between different service areas, network communication will be interrupted, or high roaming fees will be incurred, which will lead to the inability to use functions such as navigation normally. The bracket device in the existing technology cannot solve the related problems. Summary of the Invention

[0099] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further described below with reference to specific diagrams. However, the invention is not limited to the following implementation cases.

[0100] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0101] Most of the existing vehicle mounts can only fix the mobile terminal on the vehicle body and cannot provide more other functions. However, the applicant has found that for some users who like to travel by car, the vehicle mount with only a support function cannot fully meet their needs. Many self-driving users usually use mobile phones for navigation while driving. Some users even drive vehicles back and forth between different countries or regions. During the movement, the mobile terminal may cross from one service area to another. Because the terminal device usually uses a physical SIM card, the fixed physical card may not be compatible for use in different regions due to the operator. Therefore, when used across regions, network communication may be interrupted or high roaming charges may be incurred. The existing vehicle mounts cannot solve the needs of such users and can only provide a fixing function.

[0102] In order to provide a better user experience, the present invention provides a mobile terminal vehicle-mounted bracket, the mobile terminal vehicle-mounted bracket comprising:

[0103] The bracket main body module includes a shell component 1, a terminal fixing component and a fixing bracket, wherein the terminal fixing component and the fixing bracket are respectively connected to the shell component 1;

[0104] A multi-communication network module, including a physical card communication management unit, a virtual card communication management unit, and a communication link management unit. The communication link management unit selects the physical card communication management unit or the virtual card communication management unit based on the real-time network environment to provide a network and a mobile hotspot signal for the mobile terminal vehicle bracket;

[0105] A main control module connected to the communication link management unit;

[0106] a human-computer interaction module connected to the main control module, the human-computer interaction module being used to receive external control instructions to control the mobile terminal vehicle-mounted bracket, and the human-computer interaction module being further used to display network status information, wherein the network status information includes real-time network mode information, real-time network signal strength information, network account and password information, data flow remaining information, and recharge channel information of the mobile terminal vehicle-mounted bracket;

[0107] A power supply module is connected to the multi-communication network module, the human-computer interaction module and the main control module respectively;

[0108] The multi-communication network module, human-computer interaction module, main control module and power supply module are all arranged in the housing assembly 1.

[0109] The mobile terminal vehicle-mounted bracket in this embodiment is provided with a multi-communication network module, which can be used to provide a network for smart terminals near the mobile device (such as providing a network hotspot for the mobile device on the vehicle in which it is located). At the same time, since the multi-communication network module not only has a physical card communication management unit, but also has a virtual card communication management unit, the mobile terminal vehicle-mounted bracket can use the virtual card communication management unit to download the corresponding cloud card (i.e., a VSIM card) for use in addition to using the built-in physical SIM card to provide the network, thereby achieving the purpose of switching the corresponding SIM card to provide network services according to different network environments, providing a better communication environment for the driver and passengers. Not only that, the mobile terminal vehicle-mounted bracket also provides a human-computer interaction module to display network status information, so that the user can understand the network status of the mobile terminal vehicle-mounted bracket based on the network status information, such as understanding the current traffic consumption of the mobile terminal vehicle-mounted bracket, whether the traffic is provided by a physical card or a cloud card, account password information, current network signal strength, and recharge channel information. So that users can recharge their traffic in time and avoid the problem of being unable to access the Internet due to arrears, the account and password information can be provided in the form of a QR code, and users can connect to the hotspot by scanning the QR code. The recharge channel information can also be reflected in the form of a QR code, and users can scan the QR code to enter the traffic recharge platform to recharge the traffic.

[0110] The structures and working modes of the physical card communication management unit and the virtual card communication management unit can be constructed using the communication network in the prior art.

[0111] The power module can provide power to various components in the mobile terminal vehicle-mounted bracket. In this embodiment, the power module can be connected to a power supply mechanism on the vehicle to obtain power.

[0112] At the same time, since the network provided by the mobile terminal vehicle bracket is used for the mobile device, it can reduce the problem of severe heating or rapid power consumption of the mobile terminal due to networking, and improve the standby time of the mobile device during operation.

[0113] The multi-communication network module, human-computer interaction module, main control module and power supply module can all be arranged in the cavity inside the shell assembly 1, wherein the operating components and display components in the human-computer interaction module can extend to the outside of the shell assembly 1 through the opening in the shell assembly 1 to facilitate user operation and observation. The design of the human-computer interaction module can ensure visualization.

[0114] In this embodiment, the terminal fixing assembly is composed of a motor-driven mechanical gripper, wherein the terminal fixing assembly includes:

[0115] The first clamping mechanism 21 includes a first clamping plate 211 and a first rack portion 212 , wherein the first clamping plate 211 is connected to the first rack portion 212 ;

[0116] The second clamping mechanism 22 includes a second clamping plate 221 and a second rack portion 222 , wherein the second clamping plate 221 and the second rack portion 222 are connected;

[0117] The drive mechanism includes an electric motor 24 and a drive gear 25. The output shaft of the electric motor 24 is connected to the drive gear 25. The electric motor 24 is also connected to the main control module and the power module.

[0118] The first clamping mechanism 21 and the second clamping mechanism 22 are arranged opposite to each other, and the driving gear 25 is respectively connected to the first rack portion 212 and the second rack portion 222 which are parallel to each other. The electric motor 24 drives the driving gear 25 to rotate forward and reverse to drive the relative movement between the first rack portion 212 and the second rack portion 222, thereby driving the opening and closing of the first clamping plate 211 and the second clamping plate 221.

[0119] In order to improve the stability during fixation in this embodiment, a supporting structure 23 is further provided near the bottom of the housing assembly 1 to further provide supporting force.

[0120] The terminal fixing assembly composed of this mechanical gripper structure is more convenient to operate than the terminal fixing assembly that is manually opened and closed, and is more suitable for use while driving. It allows users to place or remove the mobile terminal from the mobile terminal vehicle-mounted bracket more quickly and conveniently. In some embodiments, a magnetic structure can also be used to form the terminal fixing assembly to achieve a detachable connection to the mobile terminal.

[0121] In this embodiment, the power module is also used to perform a charging function;

[0122] The power module includes a first power unit, a second power unit, a wireless charging unit 56 and a power management unit;

[0123] The power management unit is connected to the first power supply unit, the second power supply unit and the main control module respectively;

[0124] The first power supply unit supplies power to the multi-communication network module, the human-computer interaction module, the main control module, the electric motor 24 and the wireless charging unit 56 respectively;

[0125] The second power supply unit is connected to the power management unit and the electric motor 24 respectively;

[0126] When the first power supply unit fails, the power management unit drives the second power supply unit to supply power to the electric motor 24;

[0127] The human-computer interaction module is also used to display power module status information.

[0128] The design of the wireless charging unit 56 can charge some mobile devices with wireless charging capabilities. At the same time, the first power supply unit in this embodiment can serve as the main power supply component to provide power to various power-consuming components in the mobile terminal vehicle bracket, and also provide power to the wireless charging unit 56.

[0129] The second power supply unit in this embodiment is mainly used as a backup power supply, and can be composed of energy storage elements, such as supercapacitors. When the first power supply unit can obtain electric energy from the outside and operate normally, the first power supply unit supplies power to the various components in the mobile terminal vehicle bracket and charges the second power supply unit. When the first power supply unit cannot provide electric energy, the second power supply unit can be used to power the electric motor 24 to ensure that the mobile terminal vehicle bracket can drive the first clamping plate 211 and the second clamping plate 221 to separate, so that even if the first power supply unit cannot provide electric energy, the user can remove the mobile terminal from the mobile terminal vehicle bracket.

[0130] In this embodiment, the power management unit monitors the power that can be provided by the first power supply unit;

[0131] When it is detected that the electric energy provided by the first power supply unit is within a first threshold range preset by the system, the power management unit drives the wireless charging unit 56 to operate at a first charging power level;

[0132] When it is detected that the electric energy provided by the first power supply unit is within a second threshold range preset by the system, the power management unit drives the wireless charging unit 56 to operate at the second charging power level;

[0133] When it is monitored that the electric energy that can be provided by the first power supply unit is within the third threshold range preset by the system, the power management unit drives the wireless charging unit 56 to stop charging, and enables the first power supply unit to power the multi-communication network module, human-computer interaction module, main control module and electric motor 24.

[0134] By setting the control power allocation priority, more different application scenarios can be adapted. For example, in one example, if the mobile terminal vehicle mount supports the QC fast charging protocol and the software optimizes the processing flow when the power supply is insufficient, if the first threshold interval is higher than the second threshold interval, the second threshold interval is higher than the third threshold interval, and the first gear charging power is higher than the second gear charging power, in such an operating mode, when the power provided by the first power supply unit is within the first threshold interval preset by the system, the wireless charging unit 56 can provide a fast charging operation for the mobile device, when the power provided by the first power supply unit is within the second threshold interval preset by the system, the wireless charging unit 56 can provide a normal charging operation for the mobile device, and when the power provided by the first power supply unit is within the third threshold interval preset by the system, the first power supply unit drives the wireless charging unit 56 to stop charging and provide power to the remaining components. Such a power priority design can automatically adjust to reduce the wireless charging power or turn off the wireless charging function to ensure that the network infrastructure connection is uninterrupted and meet the user's timely network needs.

[0135] In an embodiment where the second power supply unit includes a supercapacitor, when the first power supply unit operates normally, it can charge the supercapacitor, and when the first power supply unit fails, the supercapacitor supplies power to the electric motor 24, effectively avoiding the problem that the mobile terminal cannot be removed from between the terminal fixing components due to an abnormality of the first power supply unit.

[0136] In this embodiment, the power module further includes:

[0137] A foreign object detection unit is connected to the power management unit and is used to detect whether a metal foreign object is present between the wireless charging unit 56 and an external receiver, and to send the detection result of whether the foreign object is present to the power management unit. Foreign object detection (FOD) is a part of wireless charging technology and is used to detect whether there is a metal object between the charger and the receiver. In this application, the foreign object detection unit is constructed using relevant foreign object detection components in the prior art to determine whether there is a foreign object between the wireless charging unit 56 and the corresponding mobile terminal, thereby avoiding charging anomalies or device damage caused by foreign objects and effectively improving safety.

[0138] In this embodiment, the input end of the first power supply unit is formed by setting a Type-C interface, which can be connected to the power supply on the car through a connecting line. The USB interface inside the car has both traditional Type-A and increasingly popular Type-C interfaces, and the output power of the traditional Type-A interface is generally 5-10W, while the high-power fast charging of the Type-C interface can support 100W. Therefore, in some applications, a dual Type-C cable can be used to connect the car and the mobile terminal vehicle bracket. In this technical solution, when using the bracket, it is considered that there will be scenarios where insufficient power supply will affect wireless charging and network stability. Therefore, the hardware design specifications support the QC fast charging protocol, and at the same time, the software optimizes the functional processing flow of the product in this scenario, giving priority to the power required for the basic network connection, automatically reducing the wireless charging power or turning off the wireless charging function, ensuring that the basic network connection power takes priority over the wireless charging power, and ensuring that the network is continuously connected.

[0139] During specific implementation, when the mobile terminal vehicle-mounted bracket has built-in wireless charging coils, communication modules and motherboards, electric motors 24, supercapacitors and other components, the product's exquisite appearance must be guaranteed, and it must be able to wirelessly charge mainstream mobile phones on the market. The position of the wireless charging coil must be fixed in the entire bracket. Therefore, sufficient antenna clearance environment must be reserved in the structural design, and the supercapacitor must be made of matching small-sized materials. An independent antenna bracket 18 is designed, and the bracket PCB board adjusts the microstrip line length and the position of the antenna IPEX seat, etc., to ensure the antenna transmission power and receiving sensitivity performance. Among them, the IPEX seat is a very small connector, which is usually used to connect the signal line between the radio frequency antenna and the circuit board.

[0140] In this embodiment, the human-computer interaction module includes:

[0141] A motor drive unit is connected to the main control module, and is used to drive the electric motor 24 to start, stop, rotate forward and reverse. In this embodiment, the motor drive unit includes an infrared sensing unit 52 and a motor control button unit, wherein the infrared sensing unit 52 is connected to the main control module, and is used to detect whether there is an object placed between the terminal fixing components. When an object is placed between the terminal fixing components, the infrared sensing unit 52 sends a signal to the main control module to drive the electric motor 24 to run, thereby driving the first clamping plate 211 and the second clamping plate 221 to move closer to each other. The motor control button unit is connected to the main control module, and is used to respond to user control instructions to drive the electric motor 24 to start, stop, rotate forward and reverse.

[0142] A display unit 41 is connected to the main control module, and is used to display at least one of the network status information and the power module status information;

[0143] The screen control unit is connected to the main control module, and is used to switch the interface displayed by the display screen unit 41.

[0144] The mobile terminal vehicle-mounted bracket in this embodiment solves the technical pain points of vehicle-mounted brackets in the prior art and has superior performance. It provides a vehicle-mounted bracket that supports converting the mobile network of VSIM (virtual SIM card) and SIM physical card into a wireless WiFi hotspot to meet the needs of multiple terminals accessing the network simultaneously and querying communication data in real time on a visual screen, and supports wireless charging. The present invention designs a mobile terminal vehicle-mounted bracket with a "network + charging + interaction" three-in-one solution in the vehicle scenario. This application adopts the operating modes of both the physical card communication management unit and the virtual card communication management unit, and utilizes the dual-mode switching of VSIM and physical SIM cards and the communication protocol technology for converting mobile network to WiFi data processing to operate.

[0145] In specific implementations, the physical card communication management unit, the virtual card communication management unit, and the communication link management unit can be composed of a CAT4 4G communication module that integrates VSIM and physical SIM dual-mode switching technology and a WiFi module. The physical card communication management unit is also connected to the SIM card holder 54, thereby enabling the mobile terminal vehicle-mounted bracket to support two different ways of accessing the Internet, namely, VSIM and physical SIM cards. When both SIM cards are valid or only one SIM card is valid, the system can switch between different SIM cards. For specific operating methods, please refer to the operating modes of physical SIM card operating devices and cloud card operating devices in the prior art. The relevant solutions will not be elaborated in more detail here.

[0146] Through the design of the infrared sensing unit 52, when the user brings the mobile terminal close to the bracket main body module, a control signal can be sent to the electric motor 24, so that the first clamping plate 211 and the second clamping plate 221 are adjusted from a state of separation to a state of proximity (or from a state of proximity to a state of separation and then proximity), thereby clamping the mobile terminal. The design of the motor control button unit allows the user to operate the motor control button unit to control the expansion or closing operation between the first clamping plate 211 and the second clamping plate 221. The design of the infrared sensing unit 52 can improve the convenience of placing the mobile terminal, and the design of the motor control button unit can improve the reliability of operation. The forward and reverse rotation of the motor control button unit can be performed by two control buttons respectively, or by the same button. In this embodiment, the first button 42 is used to constitute the motor control button unit for user operation.

[0147] In this embodiment, the human-computer interaction module further includes:

[0148] The power-on indication unit is connected to the power module and is used to indicate the connection status between the mobile terminal vehicle-mounted bracket and the external power supply.

[0149] In a specific implementation, a light-emitting component may be used to form a power-on indication unit, and the light-emitting component may be connected to the first power supply unit to indicate whether the first power supply unit is normally connected to the external power supply.

[0150] The human-computer interaction module in this embodiment includes a dual control device formed by combining an infrared sensing device and a touch device to realize the control of the electric motor 24, and then uses the electric motor 24 to drive the opening and closing operations between the first clamping plate 211 and the second clamping plate 221 on both sides through a transmission mechanism (the transmission mechanism in this application includes a first rack portion 212, a second rack portion 222 and a driving gear 25), thereby completing the taking and placing of the mobile phone.

[0151] In this embodiment, the mobile terminal vehicle bracket further includes:

[0152] The initialization driving module is connected to the main control module and is used to respond to the initialization control instruction and perform an initialization operation on the mobile terminal vehicle bracket.

[0153] During specific implementation, the screen control unit and the initialization drive module can be composed of the same button. For example, it can be set that when a button is short pressed, the button is used as a screen control unit to switch the screen displayed on the display screen 411, and when a button is long pressed, the button is used as an initialization drive module to issue an initialization control instruction to the main control module. In this embodiment, a second button 43 is used to constitute a related button, wherein a short press refers to a press time of less than a preset time, and a long press refers to a press time of more than a preset time.

[0154] In this embodiment, the main control module also performs a work log recording operation when the mobile terminal vehicle-mounted bracket is running. The design of this function facilitates the review of the operation of the mobile terminal vehicle-mounted bracket, providing a basis for subsequent equipment maintenance or troubleshooting operations.

[0155] At the same time, the mechanical structure of the dual Type-C interface used in some embodiments can not only power the vehicle bracket but also download and upgrade software for the communication PCBA main control board and capture logs in time for problem analysis and location when network communication is abnormal.

[0156] This solution expands upon existing vehicle mounts by offering several related functionalities, such as a mobile terminal vehicle mount that provides a mobile hotspot signal, charging capabilities, and displays the status of the vehicle mount. This provides users with a better user experience, offering more stable network services for vehicle passengers and avoiding high roaming charges. It can also charge the mobile terminal mounted on the vehicle mount, and through the human-computer interaction module, users can easily understand the real-time status of the vehicle mount, preventing users from experiencing travel issues due to inability to detect abnormalities in the vehicle mount. Specifically, the mobile terminal vehicle-mounted holder supports providing wireless charging functions for different mobile phones (or other mobile devices). When the communication PCBA main control board (with welded CAT4 communication module, WiFi module, SIM card holder 54 and other components) identifies a normally available physical SIM card or VSIM card, it will promptly convert the mobile network into a WiFi hotspot to meet the needs of multiple users and multiple terminal devices in the vehicle scene to connect to WiFi to access the network for video, office, playing games, etc.; the vehicle-mounted holder has a built-in display interactive screen, and the display module will feed back the obtained network status information on the display screen 411 in real time, so that users can check the communication status in time, and can switch the display screen 411 page through the holder button to quickly scan the code to connect to WiFi or recharge the traffic.

[0157] This mobile terminal vehicle-mounted holder can not only effectively fix the mobile terminal, but also improve the battery life of the mobile terminal and ensure the stability of the network connection. It also has the feature of status visualization, which can bring a better user experience, better adapt to use in a vehicle environment, and meet the needs of providing networking services for multiple terminals.

The specific shape and structure of the fixing bracket can be designed according to actual needs and are not limited here.

[0161] A second gasket 262 is further provided on the upward side of the supporting structure. The second gasket 262 is made of a flexible material, thereby playing the role of shock absorption, buffering and anti-slip.

[0162] The terminal fixing assembly in this embodiment includes a first clamping plate 211, a first rack portion 212, a second clamping plate 221, a second rack portion 222, an electric motor 24, and a drive gear 25. The first clamping plate 211 is fixedly connected to the first rack portion 212, and the second clamping plate 221 is fixedly connected to the second rack portion 222. The first clamping mechanism 21 and the second clamping mechanism 22 together form the clamping arms on both sides. The drive gear 25 is disposed between the first rack portion 212 and the second rack portion 222, so that the electric motor 24 can drive the opening and closing of the clamping arms on both sides by driving the drive gear 25. In this embodiment, a first gasket 261 is provided on the opposite side of the first clamping plate 211 and the second clamping plate 221. The first gasket 261 is made of a flexible material to provide shock absorption, cushioning, and anti-slip properties.

[0163] In this embodiment, a first mainboard 51 and a second mainboard 53 are used to secure various components. Components such as the display unit 41 (including the display screen 411), the infrared sensor unit 52, the wireless charging unit 56, the supercapacitor, and the electric motor 24 are all located on the first mainboard 51. A display foam pad 412 is also provided between the display screen and the first mainboard 51. Components such as the power docking unit 55 and the SIM card holder 54 (i.e., the holder for the physical card in the physical card communication management unit) in the multi-communication network module are located on the second mainboard 53. This solution also includes components such as a motor bracket 17 and an antenna bracket 18 to secure these components. These components are also connected and secured to other components using corresponding self-tapping screws 19. The brackets also include conductive components 6 and heat-conducting pads 57 to provide electrical and heat dissipation. A dust plug 7 can also be provided to protect the power docking unit 55 from dust. The power docking unit 55 can be constructed using a Type-C interface. The structures shown in the accompanying figures are merely examples to help those skilled in the art understand this solution, and the specific implementation is not limited to this.

[0164] like Figures 6 to 10 As shown, the mobile terminal vehicle bracket in this embodiment adopts a combination of a Cat4 4G communication module, a WiFi module, a display screen and corresponding operation buttons that integrate VSIM technology, thereby forming a multi-communication network module and a corresponding human-computer interaction module. Among them, the Cat4 communication module supports dual-mode switching technology of VSIM (i.e. virtual card) and physical SIM (i.e. physical card). The mobile network can support two different ways of accessing the Internet using VSIM and physical SIM cards. When both SIM cards are valid at the same time or only one SIM card is valid, the system can switch between different SIM cards.

[0165] The car holder supports wireless charging for different mobile phones and communicates with the main control board (i.e. Figure 4The second mainboard 53 in the system is welded with components such as Cat4 communication module, WiFi module, SIM card holder 54, etc. Figure 8 When the mobile network is recognized as a normal physical SIM card or VSIM card, it will promptly convert the mobile network into a WiFi hotspot to meet the needs of multiple users and multiple terminal devices in the vehicle scene to connect to the WiFi to access the network for video, office, and game viewing;

[0166] The vehicle-mounted bracket has a built-in interactive display screen. The display module will feed back the obtained network status information on the display screen in real time, allowing users to check the communication status in time. The bracket button can be used to switch the display screen page to quickly scan the code to connect to WiFi or recharge the data.

[0167] Generally speaking, the USB interfaces inside cars include both traditional Type-A and the increasingly popular Type-C interfaces. The output power of the traditional Type-A interface is generally 5-10W, while the high-power fast charging of the Type-C interface can support 100W. When using the bracket, it is considered that there will be scenarios where insufficient power supply will affect wireless charging and network stability. Therefore, the hardware design specifications support the QC fast charging protocol. At the same time, the software optimizes the functional processing flow of the product in this scenario, giving priority to the power required for the basic network connection, automatically reducing the wireless charging power or turning off the wireless charging function, ensuring that the basic network connection power takes priority over the wireless charging power, and ensuring uninterrupted network connection.

[0168] like Figure 6 and Figure 7 As shown, the bracket in this application has built-in wireless charging coil, communication module and mainboard, electric motor 24, super capacitor and other components while ensuring the exquisite appearance of the product, and meeting the requirements of wireless charging for mainstream mobile phones on the market. The position of the wireless charging coil must be fixed in the position of the entire bracket. Therefore, sufficient antenna clearance environment must be reserved in the structural design, the super capacitor should choose matching small-sized materials, design an independent antenna bracket 18, and adjust the microstrip line length and the position of the antenna ipex seat on the bracket PCB board to ensure the antenna transmission power and receiving sensitivity performance.

[0169] The mobile terminal vehicle mount in this embodiment features two control modes: a built-in infrared sensor and a touch switch. These control modes drive an electric motor 24, which, through a transmission mechanism (such as gears and other components), drives the opening and closing of the two clamping arms (i.e., the first clamping mechanism 21 and the second clamping mechanism 22) to facilitate the placement and placement of a mobile phone. The mount also incorporates a built-in supercapacitor capable of instantaneous energy release. This supercapacitor charges when the mount is operating normally. If the mount loses power and the system detects a power outage, the mount switches power supply paths, with the supercapacitor taking over power to the control module and motor drive circuit, thereby controlling the opening and closing of the two clamping arms via the motor.

[0170] The dual Type-C interface mechanical structure used by the bracket can not only power the vehicle bracket, but also download and upgrade software for the communication PCBA main control board, and timely capture logs for problem analysis and location when network communication is abnormal.

[0171] like Figure 8 As shown, in this embodiment, components such as the UIS8310AM chip, the SR3595D chip, the radio frequency module, and the WIFI chip are used to form a multi-communication network module consisting of a physical card communication management unit, a virtual card communication management unit, and a communication link management unit. This multi-communication network module is also connected to a power management component composed of an SC2720A chip, thereby achieving compatibility between physical and virtual card modes. Based on the real-time network environment, either the physical card communication management unit or the virtual card communication management unit can be selected to provide network and mobile hotspot signals for the mobile terminal vehicle-mounted bracket.

[0172] like Figure 7 As shown, the multi-communication network module in this application is mainly composed of a communication PCBA control board, a 4G module, a WiFi module and a SIM card holder 54; the specific features of each component are as follows:

[0173] (1) Communication PCBA motherboard

[0174] The PCBA motherboard is a circuit board. The VSIM Cat4 module, SIM card holder 54, WiFi module, Type-C connector, etc. can be welded on it. After receiving power from the bracket PCBA motherboard, the module establishes communication with other modules through the lines on the PCBA motherboard, converting the module mobile network into an intermediate bridge for WiFi local area network, realizing data transmission and interaction, and meeting users' needs for accessing the network through wireless WiFi.

[0175] Function: Physically integrates and welds key components such as the VSIM 4G Cat4 module, SIM card holder 54, WiFi module, and Type-C interface; receives power input from the bracket PCBA motherboard and distributes power to the 4G module and WiFi module; realizes electrical connections between modules through PCB wiring (such as the data link from 4G module to WiFi module to display); manages dual-mode switching between the VSIM and physical SIM card; converts mobile network data (4G) into WiFi LAN data packets and sets data routing; provides fault status diagnosis and sends real-time data to the human-computer interaction display;

[0176] Problem Solving: By integrating 4G / WiFi / power management functions through high-density PCB design, the hardware system is miniaturized to solve the problem of decentralized traditional power supply / network communication modules, and to address the issues of invisible device status and difficult fault maintenance.

[0177] (2) Support VSIM Cat4 communication module

[0178] As the core module for processing and transmitting mobile network communication data of the vehicle-mounted bracket, it supports the 4GLTE Cat4 standard of VSIM technology, and supports online switching between physical SIM cards and VSIM cards, converting cellular network data into Ethernet data frames that can be processed by the WiFi module;

[0179] Problem Solving: This solution addresses the issue of traditional network solutions only supporting physical SIM cards, resulting in complete network disconnection in signal-blind areas. It also addresses the issues of poor cross-border network compatibility, the need to replace SIM cards during international roaming, and the high costs associated with these cards.

[0180] (3) WiFi module

[0181] Convert 4G network (via VSIM / physical SIM card) into WiFi signal to establish vehicle-mounted LAN, serving as a data exchange channel between 4G communication module and terminal equipment, realizing protocol conversion between mobile network (4G) and LAN (WiFi), and supporting concurrent access of multiple terminals (mobile phones / tablets / laptops, etc.) (the maximum number of connections needs to be specified, such as 16);

[0182] Problem Solving: The integrated WiFi module independently provides WiFi hotspots, and the mobile phone only serves as a terminal for access, reducing dependence on mobile phone hotspots and external vehicle routers, reducing the load on the mobile phone and the additional wiring of the vehicle router;

[0183] (4) SIM card holder 54

[0184] Realize the physical and electrical connection between the SIM card and the communication PCBA motherboard, as well as transmit key data such as ICCID, IMSI, authentication key (Ki), and support the mechanical insertion / removal of the physical SIM card. At the same time, the system supports dual-mode switching between VSIM and physical SIM card;

[0185] Problem Solving: The SIM card holder 54's high-reliability connection design and dual-mode intelligent switching capability not only retains the flexibility of the physical SIM card, but also achieves seamless network redundancy through VSIM, solving the ultimate pain point of network connectivity in vehicle scenarios - the contradiction between environmental adaptability and continuity.

[0186] like Figure 6 As shown, the power module in this embodiment is composed of a wireless charging component, a super capacitor and a dual Type-C mechanism. The specific features of each component are as follows:

[0187] (1) Wireless charging coil

[0188] The wireless charging unit 56 is composed of a plurality of power levels, and when the bracket receives external power and the power supply is normal, it converts the electrical energy into an alternating magnetic field and then converts it back into electrical energy to charge the mobile phone. In a specific implementation, the wireless charging coil can achieve intelligent power adaptation of 5W-7.5W-10W-15W, and can dynamically adjust the power according to the battery status of the mobile phone during operation. It is compatible with Apple, Android and other mobile phones (in a specific implementation, other power levels can also be used to provide electrical energy according to actual needs, and this example is not limited thereto);

[0189] Problem Solving: Solve the low efficiency of traditional car charging and the compatibility issues of multiple brands of mobile phones in the market. Dynamically adjust the power according to the mobile phone power level and bracket temperature monitoring strategy to ensure product safety and lifespan.

[0190] (2) Supercapacitor

[0191] The supercapacitor constitutes the second power supply unit, i.e. the backup power supply of the bracket. It can temporarily store electrical energy and release the energy instantly when needed, providing short-term power for the mechanical structure of the bracket (such as the clamping arms on both sides);

[0192] It can serve as a backup power source. The supercapacitor can temporarily store electrical energy and release it instantly when needed, providing short-term power to the mechanical structure of the bracket (such as the clamping arms on both sides), allowing it to complete the opening or closing action, avoiding manual forced disassembly of the phone.

[0193] Problem Solved: Traditional in-car wireless chargers lose power immediately after the vehicle is turned off. If the phone is not removed in time, the bracket must be manually opened, which can easily damage the bracket or scratch the phone. Supercapacitors solve this mechanical operation problem by providing temporary power supply. The physical energy storage mechanism of supercapacitors (no chemical reaction) makes them more stable in vibration, high temperature or low temperature environments, and safer than traditional batteries (no risk of leakage or explosion).

[0194] (3) Bracket Type-c interface

[0195] The power input end of the first power supply unit is connected to the Type-C USB interface of the car through a data cable. After the car is ignited, the car bracket can start up after receiving power and provide power for the connected functional modules to ensure stable operation of the device in the car scene.

[0196] Problem Solving: Improved charging speed, supported plug-and-play of peripherals, and achieved the upgrade from "single charging" to "in-vehicle intelligent hub".

[0197] (4) Communication PCBA main control board Type-c interface

[0198] This interface is a log capture interface and debugging diagnosis interface when network communication is abnormal. It can quickly capture logs to analyze problems and download and upgrade firmware for the communication mainboard.

[0199] Problem Solving: The Type-C interface directly outputs module logs, and network abnormality codes are analyzed in real time, eliminating the need for disassembly maintenance.

[0200] The human-computer interaction module in this embodiment includes a display screen, an LED indicator light, a second button 43, an infrared sensor, and a touch sensor constituting the second button 43. The specific features of each component are as follows:

[0201] (1) Display screen

[0202] Device status monitoring and real-time status visualization, real-time display of network communication data such as signal strength, network speed, number of WiFi terminal connections, total package traffic, used traffic, etc.; as an interactive control center, physical buttons are used to switch screen display pages, quickly connect to WiFi and use traffic recharge QR codes, etc.

[0203] Solve the problem: The status of the traditional car bracket device is not visible, and it relies on mobile phone APP or computer to switch multiple interfaces to view the network / charging status. At the same time, there is no warning when the device traffic exceeds the limit;

[0204] (2)LED indicator

[0205] After the PCBA mainboard of the vehicle bracket is powered on, the LED light promptly reports that the bracket is working properly. The bracket signal light status display: the red light is on: the bracket is powered normally, and the blue light is on: the wireless charging is normal;

[0206] (3) Button

[0207] Multi-mode command input, single-click screen page switching Press and hold for 5 seconds to enter firmware upgrade mode (USB debugging port activated), and press and hold for 15 seconds to restore to factory settings (clear VSIM configuration / network parameters);

[0208] Problem Solving: The bracket button adopts a composite structure design and multi-level operation logic to solve the problems of restoring factory settings and needing to connect to a PC to execute AT commands (which is inoperable for ordinary users), firmware upgrades requiring disassembly and short-circuiting test points (which has high operation risks), and single-click cyclic switching of core pages.

[0209] (4) Infrared and touch sensing module (i.e., a module consisting of an infrared sensor and a touch sensor constituting the second button 43)

[0210] Infrared transmitters and receivers, as well as touch sensors, accurately detect changes in sensing signals, triggering the control circuit to start the motor. The motor drives the opening and closing of the clamping arms on both sides through the transmission mechanism (such as gears and other transmission components) to complete the removal and placement of the mobile phone.

[0211] Problem Solving: The infrared sensing module achieves a more ergonomic operating experience for hovering load gesture triggering than physical pressing through non-contact precise detection, environmental robustness design and graded energy efficiency control. At the same time, the dual sensing mechanism reduces the risk of accidental clamping.

[0212] The terminal fixing assembly in this embodiment includes a motor + a clamping arm + a transmission mechanism, which has the following characteristics:

[0213] The motor drives the opening and closing of the clamping arms on both sides through a transmission mechanism (such as gears) to complete the placement and removal of the phone. In specific implementation, the clamping force can be fed back in real time through a pressure sensor (range 0-20N), and the stepper motor can be used to achieve dynamic clamping force control for both bare and cased phones. The opening and closing of the metal clamping arms can be controlled with balanced force and speed, extending the service life of the bracket. Through intelligent interactive linkage, wireless charging is automatically activated when the clamping arms close, and the aluminum alloy clamping arms have integrated heat dissipation to dissipate heat generated by wireless charging.

[0214] Problem Solving: The first gasket 261 composed of a silicone anti-skid pad built into the aluminum alloy base avoids damage to the device and the device falling off in a vibration environment. At the same time, it is compatible with devices of multiple sizes and has high safety.

[0215] In other embodiments, other components may be used to form components such as multiple communication network modules and power supply systems, and are not limited to the illustrated examples.

[0216] The operation process of the mobile terminal vehicle bracket in this embodiment can be referred to Figure 9 As shown, the operation process is as follows:

[0217] After fixing the car WiFi wireless charging bracket to the car air conditioner outlet with a hook, use a USB data cable to connect one end of the bracket's Type-C port and the other end to the car's Type-C port. In some cases, if the bracket fails to receive power successfully, it can be turned off.

[0218] After the bracket is powered on, each module enters initialization. The LED indicator judges the power supply result of the bracket. If the power supply is normal, the indicator light will be red and steady.

[0219] The communication PCBA main control reads the Cat4 module SIM card (physical SIM card and VSIM) information, WiFi module, product configuration items and other information. After the reading is completed, it enters the initial state. At the same time, the display module displays the obtained information such as network signal strength, the number of connected WiFi terminals, and the current SIM card package traffic on the display screen. At this time, mobile phones, tablets and other terminals can be successfully connected to the WiFi hotspot to access the network for office work, chatting, playing games, watching videos, etc. When the communication PCBA main control detects that a terminal is connected to the WiFi hotspot and generates data transmission, the display module will obtain and update real-time network status information such as the number of successfully connected WiFi terminals, the data transmission rate displayed as high, medium and low respectively, and the remaining traffic of the current SIM card package.

[0220] After initialization, the infrared sensing module enters a standby state. When the infrared transmitter and receiver detect an object entering the sensing area, the infrared rays are reflected, and the receiver detects a signal change, which triggers the control circuit to start the motor. The motor drives the two side clamps to open and close through a transmission mechanism (such as gears and other components), completing the process of taking the phone in and out. After initialization, the touch sensing module on the bracket rear shell 13 enters a standby state. When a finger touches a specific touch area on the bracket rear shell 13, the touch module sensor detects a signal change, which triggers the control circuit to start the motor. The motor drives the two side clamps to open and close through a transmission mechanism (such as gears and other components), completing the process of taking the phone in and out.

[0221] After receiving power, the wireless charging module of the bracket performs a joint detection of FOD foreign objects and infrared sensing modules. If no mobile phone or foreign objects are detected, the wireless charging module enters standby mode. If a mobile phone is detected, it performs identity authentication through the wireless charging protocol handshake and receives the RX capability data packet. It negotiates to automatically adapt to charging the mobile phone at a power of 5W-7.5W-10W-15W. Multiple temperature measurement points are set during the charging stage. If the temperature threshold is exceeded, the charging power is adjusted to downgrade. When charging continues at the adjusted power and the temperature is monitored to return to normal, charging continues until the final charging process is completed.

[0222] The bracket successfully receives power when the system is working normally to charge the supercapacitor. When the system detects that the bracket is powered off and switches the power path, the supercapacitor takes over the power supply and supplies power to the control module and motor drive circuit. The motor maintains the open operation of the clamping arms on both sides through the transmission mechanism (such as gears, etc.) to ensure that the mobile phone can be taken out and avoid being trapped.

[0223] When the display screen updates the network status information in real time, you can press the button on the bracket to switch the screen page, so that you can scan the QR code to quickly connect to the WiFi hotspot and recharge the current SIM card traffic.

[0224] like Figure 10As shown, with the mobile terminal vehicle mount of this solution, users can use the human-computer interaction module to assist in fault analysis operations, as follows:

[0225] 1. After the bracket receives external power, if the LED light does not light up, it indicates that the bracket is receiving power abnormally and needs to be troubleshooted. At this time, the abnormality can be checked by checking the quality of the bracket Type-C socket / LED indicator device and the welding process. In addition, the problem can be analyzed and solved by confirming whether the power supply circuit of the bracket PCBA motherboard system is abnormal.

[0226] 2. When the communication PCBA main control board is initialized or in use, if no available VSIM / physical SIM card is detected, it indicates that the SIM card and mobile network are abnormal. The SIM card icon on the display will indicate an abnormality and there will be no mobile network icon and SIM card traffic statistics. At this time, you can analyze and solve this problem by checking whether the bracket is equipped with an available VSIM and physical SIM card or checking whether there are any abnormalities in the communication mainboard hardware or software.

[0227] 3. When the communication PCBA main control board is initialized or detects abnormal WiFi function and basic information during use, mobile phones and other terminals cannot connect to the WiFi hotspot or connect to WiFi but cannot access the network, and the display screen does not have basic information such as the WiFi icon / SSID / PWD. In this case, you need to analyze and solve this problem by checking whether the hardware / firmware of the communication PCBA main board and display screen are faulty.

[0228] 4. If the wireless charging function of the bracket malfunctions and cannot charge the phone normally, you can analyze and solve the problem by checking whether there is a fault in the wireless charging hardware of the bracket. You can also confirm whether the wireless charging protocol supported by the phone is compatible with the bracket.

[0229] 5. When the motor fails to drive the clamping arms on both sides to open and close, you can confirm whether there is any abnormality in the assembly of the motor structure through testing. You can also analyze and solve the problem through the bracket PCBA motherboard infrared / touch sensor / motor power supply circuit, etc.

[0230] The use of relevant structures can better realize fault troubleshooting and analysis, effectively enhance the user experience, and assist users to perform some fault troubleshooting on their own when outdoors.

[0231] The mobile terminal vehicle bracket in this embodiment has the following technical advantages:

[0232] Intelligent network communication: In addition to providing wireless charging for mobile phones, the vehicle mount integrates a Cat4 4G communication module that supports VSIM technology, a WiFi module, and an interactive display. This allows the physical SIM card or VSIM card to be used to instantly convert the mobile network into a WiFi hotspot, meeting the needs of multiple users and multiple terminal devices in vehicle scenarios to connect to the WiFi network for video, office work, and gaming. The Cat4 communication module supports dual-mode switching between VSIM and physical SIM, providing convenient and real-time stable communication network.

[0233] Display screen visual operation: The vehicle-mounted bracket has a built-in interactive display screen. The display module will feedback the acquired network status information on the display screen in real time, allowing users to check the communication status in time. The bracket button can be used to switch the display screen page to quickly scan the code to connect to WiFi or recharge the data.

[0234] Multi-power system + dual Type-C ports: The bracket's built-in supercapacitor can release energy instantly. When the bracket is working normally, it can charge the supercapacitor. When the bracket loses power, it can power the motor to open and close the two clamping arms to pick up and place the phone. The dual Type-C ports not only ensure the bracket's normal power supply, but also enable timely capture of system logs in the event of network anomalies to locate and analyze problems and later firmware upgrades.

[0235] When the power supply is insufficient, a high-priority network connection processing solution is adopted: the bracket supports the QC fast charging protocol and software optimization of the processing process when the power supply is insufficient. By automatically adjusting to reduce the wireless charging power or turning off the wireless charging function, it ensures that the basic network connection is uninterrupted and meets the user's timely network needs.

[0236] Through the above design scheme, the present invention pioneered the "charging + network + interaction" three-in-one solution in the vehicle scenario, realizing the upgrade from the traditional vehicle-mounted wireless charging bracket to "mobile network and WiFi wireless, intelligent, and visualized", meeting the needs of users in the Internet of Things era for high-speed, low-latency, multi-connection intelligent networked vehicle WiFi wireless charging brackets.

[0237] The preferred embodiments of the present invention have been described in detail above. It should be understood that numerous modifications and variations based on the concepts of the present invention are possible without inventive effort by those skilled in the art. Therefore, any technical solution that can be derived by one skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
