Description

Technical Field

[0001] The present application relates to the technical field of mobile phone auxiliary accessories, and in particular to a mobile phone live broadcast companion stand. Background Art

[0002] In the mobile internet era, mobile live streaming, as an emerging communication method, has rapidly developed in recent years. Mobile live streaming typically requires the following equipment: a mobile phone or computer, a phone stand, a fill light, a sound card and microphone, a phone stabilizer, and network equipment. The mobile phone or computer is the most basic tool, requiring good camera and recording capabilities. The phone stand stabilizes the phone to prevent shaky footage. The fill light improves lighting conditions for clearer live footage. The sound card and microphone enhance sound quality. A phone stabilizer ensures a stable image for outdoor live streaming. Network equipment provides a stable connection for a smooth live stream. During extended live streams, streamers may encounter issues like a dead phone or overheating. To prevent these issues, streamers typically prepare a power bank and a heat sink (such as a semiconductor cooling clip that clips onto the back of the phone, a fan, ice packs, or a wet towel) before the live stream begins. Therefore, to ensure a smooth live stream, the current equipment required is complex and complex, making installation, connection, and operation inconvenient for users, and generally requires the collaboration of multiple people.

[0003] Individual broadcasters often use mobile phones, power banks, heat dissipation clips, phone stands, fill lights, headphones, etc. for live broadcasts. When broadcasting for a long time, they will connect the phone to the power bank and clip the heat dissipation clip on the back of the phone. Then, they will place the phone on the phone stand or hold it in their hand while walking and broadcasting. The fill light can be turned on when needed. This live broadcast method uses less equipment and is easy to move, making it suitable for scenarios such as tourism explanations. Although these live broadcast equipment can meet basic live broadcast needs, they still have the following usage problems when broadcasting for a long time or in remote areas:

[0004] When a mobile phone is operating normally, it can generally only use one data network. Even if the mobile phone itself is equipped with multiple traffic cards that can provide different data networks, it can only support a single network by switching networks. Therefore, when conducting mobile phone live broadcasts in remote areas, there is usually a problem of poor network signal, which causes video freezes and affects the live broadcast effect. In addition, mobile phone live broadcasts generally rely on the camera built into the mobile phone, which can only display a single perspective when shooting. The live broadcast picture is not diverse enough and the display effect is not good. If multi-angle shooting is required, additional mobile phones or cameras and other equipment are required. In addition, the mobile phone needs to be connected to a power bank for continuous charging, and the mobile phone sockets are limited. In addition, personal live broadcasts have limited manpower. The more equipment there is, the more difficult it is to move and carry. Therefore, the current personal mobile phone live broadcast effect is to a certain extent restricted by the equipment that the individual can carry and use. Therefore, it is necessary to propose a new technical solution to solve the problems existing in the existing technology. Utility Model Content

[0046] Therefore, the mobile phone live broadcast companion seat provided in the present application fixes the mobile phone through the mobile phone mounting seat 2, and installs the battery 7 through the battery mounting seat. The battery 7 maintains the operation of the mobile phone live broadcast companion seat and can also charge the mobile phone; it helps the mobile phone to connect to the signals of multiple external devices through multiple extended data interfaces, solving the problem that the number of interfaces on the mobile phone is limited and it cannot be connected to more devices, resulting in limited use of the mobile phone during live broadcast; the mobile phone live broadcast companion seat is provided with a USB interface that can be connected to a wireless Internet card tray, which can provide a network for the mobile phone and improve the network status of the mobile phone when live broadcasting in remote areas; the mobile phone live broadcast companion seat can also send audio and video signals shot by external devices (such as mobile phones, cameras, etc.) to the mobile phone through the audio and video input interface to realize multi-angle shooting, enhance the diversity of the live broadcast picture, and increase the diversity and viewing of the live broadcast.

[0047] In a preferred embodiment of the present application, a cooling fan assembly can be added to the mobile phone live broadcast companion seat to cool the mobile phone. Specifically, a cooling fan assembly can be set in the inner cavity of the main body shell 1, and the power circuit module can be electrically connected to the cooling fan assembly, so that the cooling fan assembly can be powered by the battery 7. The cooling fan assembly mainly includes a cooling fan 6 installed toward the mobile phone mounting seat 2, an air outlet 4 is provided on the mobile phone mounting seat 2, and an air inlet is provided on the main body shell 1. The air inlet can be provided in multiple numbers on the main body shell, and the air inlet can be grid-shaped.

In order to facilitate the control of the opening and closing of the cooling fan, a switch button for opening and closing the cooling fan is provided on the main body shell.

[0048] In the specific processing and manufacturing, a switch button for turning on and off the cooling fan can be set on the mobile phone live broadcast companion seat, and a switch button for turning on and off the power of the device can be set. Of course, the switch button for turning on and off the power of the device and the switch button for turning on and off the cooling fan can also be integrated into one, for example, long pressing (pressing for 2-3 seconds) the switch button turns on and off the power, and short pressing (pressing for 1 second) the switch button turns on and off the cooling fan. This application preferably uses a switch button to control the opening and closing of the device power and the cooling fan, such as Figure 3 The switch button 14 in.

[0049] In a preferred embodiment of the present application, one or two HDMI input interfaces can be provided, and of course, more can be provided as needed. The HDMI input interface can be used to connect the mobile phone live broadcast companion to other mobile phones, cameras, and other external shooting devices, and then the mobile phone live broadcast companion transmits the image signal to the mobile phone to achieve multi-angle shooting, thereby improving the diversity of the live broadcast image.

[0050] Specifically, the above-mentioned processing and output module mainly includes an HDMI signal processing chip, a USB hub chip, a central processing chip and a power management chip; the above-mentioned power circuit module is mainly connected to the battery and provides power for the processing and output module and the mobile phone to maintain the normal operation of the device.

[0051] See also Figure 7 The HDMI input interface is connected to the HDMI signal processing chip (MS2130) through an HDMI signal cable. The HDMI signal processing chip is used for decoding, transmitting or converting HDMI signals. It can convert HDMI signals into other types of signals, such as USB or other digital interface signals, which enables HDMI signals to be transmitted through other interfaces. In addition, the HDMI signal processing chip is also responsible for necessary processing and enhancement of the HDMI signal, such as noise removal and signal amplification, to ensure that the signal quality is maintained during the transmission process.

[0052] Continue to see Figure 7 The output end of the HDMI signal processing chip is connected to the input end of the USB hub chip (USB HUB VL817). The USB hub chip is specially used to expand the number of USB interfaces. It allows multiple USB devices to be connected through one USB interface. It usually supports multiple USB 3.0 interfaces, so as to conveniently connect multiple external devices to the mobile phone live broadcast companion seat. During data transmission, it is also responsible for managing and allocating the bandwidth of USB data transmission to ensure that the data transmission between multiple devices will not interfere with each other, while maintaining a stable transmission speed.

[0053] Therefore, the HDMI signal processing chip converts the HDMI signal into a USB signal after processing it, and then the USB hub chip distributes the USB signal it receives to multiple USB ports for transmission to the mobile phone through the TYPE-C interface.

[0054] Continue to see Figure 7 The input of the USB hub chip can be connected to the USB port for connecting a wireless network card holder and the device connection port for connecting a wireless microphone. The signal input of the TYPE-C port for connecting to the mobile phone signal is connected to the output of the power management chip (VL103 chip) and the output of the USB hub chip, respectively, to connect the external device signal to the mobile phone and charge the mobile phone. The power management chip can distribute power and charge management, distribute battery power to different parts of the circuit, and appropriately switch or distribute between charging and battery power.

[0055] Continue to see Figure 7 , you can also set a TYPE-C interface for charging the battery on the mobile phone live broadcast companion seat. The TYPE-C interface is connected to the power circuit module. When in use, you can connect the TYPE-C interface to the mobile phone charging head, such as Figure 2 The second TYPE-C interface 10.

[0056] Continue to see Figure 7 The power circuit module's input is connected to the battery (F970 battery), while its output is connected to the inputs of the USB hub chip, the power management chip, and the CPU chip. The drive motor that drives the cooling fan is connected to the CPU chip's output. Therefore, the power circuit module can supply battery power to the processing output module, the phone, and the cooling fan.

[0057] In a preferred embodiment of the present application, Figure 1 、 6 Two supporting protrusions are provided on the first side of the main body housing 1. A mounting slot for mounting a mobile phone is formed between the two supporting protrusions. Anti-slip pads 3 are provided on the sidewalls of the mounting slot. An air outlet 4 is provided at the bottom of the mounting slot. A cooling fan 6 is located near the air outlet 4. The bottom of the mounting slot is also provided with a plurality of air guide grooves 5. These air guide grooves 5 are distributed around the air outlet 4 and are in air communication with the air outlet 4. The anti-slip pads 3 can secure the mobile phone, preventing it from accidentally falling and improving installation stability. The air outlet 4 provided at the bottom of the mounting slot can increase the air circulation speed on the back of the mobile phone, thereby cooling it. The air guide grooves 5 provided around the air outlet 4 can disperse the air blown by the cooling fan 6 to the entire back of the mobile phone, expanding the cooling area and improving the cooling effect.

[0058] It can be seen that the mobile phone live broadcast companion stand provided in this application is integrated with multiple functional modules, which can charge and cool the mobile phone during live broadcast, and connect the mobile phone, camera, wireless network card tray, wireless microphone, etc. to the mobile phone through the extended data interface on it, thereby improving the use effect of the mobile phone, providing multi-angle shooting for live broadcast, and improving the network, thereby improving the effect of user's mobile phone live broadcast.

[0059] In a preferred embodiment of the present application, two wireless network card holders can be plugged into the main body shell of the mobile phone live broadcast companion seat. The SIM traffic card inserted in each wireless network card holder belongs to a different operator, and the operator to which the SIM traffic card inserted in the mobile phone belongs is also different from the operator of the SIM traffic card inserted in the two wireless network card holders. For example, a China Telecom SIM traffic card is inserted into the mobile phone, a China Mobile SIM traffic card is inserted into the wireless network card holder installed in a first USB3.0 interface 11, and a China Unicom SIM traffic card is inserted into the wireless network card holder installed in another second USB3.0 interface 12. When in use, the networks provided by the three major operators can relay each other, which can improve the live broadcast network status when broadcasting in remote areas and ensure the smoothness and clarity of the video.

[0060] The purpose of inserting the wireless network card tray is to provide an additional network connection for the mobile phone. When the mobile network signal is poor, the wireless network card tray can switch between the networks of different operators to improve the smoothness and clarity of the video.

[0061] To achieve multi-network aggregation, you can install network aggregation software or services on your mobile phone, such as the Tencent Cloud Jutong system. After connecting the mobile live broadcast companion station of this application to your mobile phone, the two wireless network card trays connected to the mobile live broadcast companion station can perform multi-network aggregation with the mobile phone network (mobile phone 4G / 5G network and mobile phone WIFI), and multiple networks can jointly maintain high-definition video playback. Therefore, the mobile live broadcast companion station provided by this application provides equipment support for multi-network aggregation to improve the smoothness and clarity of video.

[0062] It is also possible to achieve multi-network aggregation of four networks through a wireless network card tray, mobile phone 4G / 5G network, mobile phone WIFI and USB to RJ45 wired network.

[0063] In actual use, one of the two wireless network card trays mentioned above can be replaced with a video capture card or USB camera to realize HDMI signal input. In addition, an HDMI signal input connected to the HDMI input interface and a mobile phone camera video signal can be added to achieve three-way network aggregation (one wireless network card tray, mobile phone 4G / 5G network and mobile phone WIFI) and three-way image output.

[0064] Therefore, the mobile phone live broadcast companion stand provided by this application integrates HDMI input, USB interface expansion, mobile phone charging, and mobile phone heat dissipation functions. It can also plug in multiple wireless network card holders to improve the live broadcast network status and provide equipment support for multi-network aggregation. Using the mobile phone live broadcast companion stand provided by this application can achieve high-definition live broadcast of mobile phones in weak network conditions, and charge and dissipate heat for the mobile phone while live broadcasting, ensuring long-term stable high-definition live broadcast of the mobile phone. The mobile phone live broadcast companion stand can be applied to live broadcast apps of Android and Apple systems, such as V Director Screen Recording App, Kuaishou App, Douyin App, etc.

[0065] The mobile phone live broadcast companion seat provided in this application can access HDMI signals (such as HDMI signals from mobile phones, cameras, director's desks, computers, etc.) through the HDMI input interface, and combine with the mobile phone camera image to achieve multi-channel image output, providing multi-angle images for the live broadcast screen, enriching the live broadcast content, and can meet the high-definition live broadcast under weak network conditions, realize professional-level director live broadcast functions, and meet the application of large-scale live broadcast sites.

[0066] The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features). In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
