Description

Technical Field

[0001] This utility model relates to the technical field of live streaming shooting auxiliary equipment, and in particular to a heat dissipation bracket for multi-mobile phone live streaming. Background Technology

[0002] With the widespread adoption of live-streaming e-commerce, simultaneous streaming across multiple platforms, and multi-camera recording of short videos, actual filming often requires placing two or more mobile phones side-by-side in the same direction to simultaneously stream, record, and charge. Under high load, the processors, radio frequency modules, and batteries of multiple phones continuously generate heat, easily leading to increased device temperatures. This can trigger system throttling, frame drops, stuttering, automatic screen brightness reduction, and even interruptions in streaming, affecting the stability and continuity of the live stream.

[0003] In existing technologies, most multi-phone stand products focus on clamping and fixing, angle adjustment, and camera placement, typically lacking an integrated effective active airflow cooling structure. Even when cooling devices are included, they often employ individual fans or heat sinks for each phone, resulting in complex structures, messy cables, noise accumulation, and inconvenient assembly and maintenance. Furthermore, they are not conducive to integrated setups for desktop live streaming scenarios. In addition, when multiple phones are arranged side-by-side, the heat generated by different positions often varies, especially for phones in the middle, which are prone to heat buildup due to the combined heat from adjacent phones. Without airflow distribution and balancing mechanisms, the airflow and air pressure received by each phone are inconsistent, leading to uneven cooling. Moreover, multi-phone setups usually require adjusting the spacing and position of the phones according to the screen composition. Existing fixed-point air outlets or fixed vent structures struggle to maintain effective alignment and stable airflow after camera movement, easily leading to air leakage, reduced airflow, or insufficient cooling in some positions.

[0004] Therefore, there is an urgent need for a heat dissipation bracket structure with high structural integration, adaptable to multi-camera sliding and adjusting distance, and capable of stable air intake and balanced airflow distribution across multiple cameras at different adjustment distance positions, in order to improve the heat dissipation reliability and operational stability in multi-mobile live streaming / recording scenarios.

The airflow then enters the air guide cover through the guide channel inside the slide and is directed towards the air outlet on the back of the corresponding phone. This solves the problems of inconsistent heat dissipation, unstable airflow, and overheating caused by the variable phone mounting positions in scenarios with multiple phones broadcasting simultaneously.

[0027] Please see Figure 1-3In one possible implementation, a heat dissipation bracket for multi-mobile phone live streaming includes a bracket body 1 and at least two mobile phone mounting components 8 disposed on the bracket body 1. The bracket body 1 is provided with a hollow crossbeam 2, and a main air duct 3 extending along its length is formed within the crossbeam. The main air duct 3 sequentially includes an upstream air supply section and a downstream air intake section.

[0028] A centralized air supply assembly 6 is installed on the hollow crossbeam 2. The centralized air supply assembly 6 includes a fan and its mounting base. The fan outlet is connected to the upstream air supply section and is used to supply air to the main air duct 3. A distribution chamber 4 is provided inside the crossbeam, located between the upstream air supply section and the downstream air intake section, and is connected to both. A flow equalization component 5 is provided at the outlet of the distribution chamber 4. The flow equalization component 5 is located between the distribution chamber 4 and the downstream air intake section, so that the airflow undergoes at least one of rectification treatment and throttling treatment before entering the downstream air intake section.

[0029] A continuous air intake trough 7 extending along the length of the crossbeam is provided on its lower side, communicating with the downstream air intake section to provide a continuous air intake channel for the slidingly arranged mobile phone mounting components 8. Each mobile phone mounting component 8 includes a slide base 9 that can slide along the length of the crossbeam and a clamping part provided on the slide base 9 for clamping and fixing the mobile phone. The slide base 9 is provided with an air intake interface that mates with the continuous air intake trough 7. A sealing ring is provided around the periphery of the air intake interface, and the sealing ring forms a sliding seal fit with the edge of the groove of the continuous air intake trough 7 to maintain a sealed connection between the air intake interface and the continuous air intake trough 7 during sliding.

[0030] The slide 9 has an internal airflow channel that connects to the air duct 10 located near the back of the corresponding mobile phone. The air duct 10 has at least one air outlet facing the back of the mobile phone to direct airflow to the heat dissipation area on the back of the mobile phone.

[0031] In this embodiment, the fan can be an axial flow fan or a turbine fan; the hollow crossbeam 2 can be made of metal or engineering plastic to balance structural strength and lightweight; the sealing ring can be an O-ring, foam sealing ring or lip sealing ring to adapt to different sealing requirements; the slide 9 achieves stable sliding through guide rails or guide grooves; the air outlet of the air guide shroud 10 can be an array of multiple air outlet holes to adapt to different mobile phone sizes and improve airflow uniformity.

[0032] Please see Figure 2 In one possible implementation, a centralized air supply assembly 6 is disposed at one end of the hollow crossbeam 2. The centralized air supply assembly 6 includes a fan and a mounting base. The air outlet of the fan is connected to the upstream air supply section of the main air duct 3 to supply air to the main air duct 3. The airflow enters the distribution cavity 4 disposed between the upstream air supply section and the downstream air intake section along the main air duct 3, and undergoes at least one of rectification and throttling treatment by the flow equalization element 5 disposed at the air outlet of the distribution cavity 4 before entering the downstream air intake section, thereby providing airflow to the continuous air intake trough 7 connected to the downstream air intake section.

[0033] The centralized air supply component 6 is located at one end of the hollow crossbeam 2, which facilitates the arrangement and centralized installation of the fan and its power supply cables, and helps to reduce the structural complexity of the duct connection. The connection between the centralized air supply component 6 and the hollow crossbeam 2 can adopt a snap-fit, screw fastening, or quick-release structure for easy assembly or maintenance.

[0034] Please see Figure 1-3 In one possible implementation, the distribution cavity 4 is located in the middle section of the hollow crossbeam 2 along its length. The distribution cavity 4 is situated between the upstream air supply section and the downstream air intake section of the main air duct 3, and is connected to both the upstream air supply section and the downstream air intake section. A flow equalization element 5 is provided at the air outlet of the distribution cavity 4. After the airflow enters the distribution cavity 4 from the upstream air supply section, it undergoes at least one of rectification and throttling treatment through the flow equalization element 5 before entering the downstream air intake section to supply air to the continuous air intake trough 7 connected to the downstream air intake section.

[0035] Setting the distribution chamber 4 in the middle section of the hollow crossbeam 2 allows the airflow to be distributed and regulated in the middle of the crossbeam before entering the downstream air intake section. This helps to reduce the distance difference between the installation positions of different slides 9 and the distribution position, thereby improving the consistency of airflow distribution at each mobile phone position.

[0036] The distribution cavity 4 can be configured as an integral cavity structure or an independent embedded module according to the cross-section of the beam; its cavity size and position can be set according to actual needs, such as by combining airflow test or simulation results.

[0037] Please see Figure 1-3 In one possible implementation, the flow equalization component 5 includes at least one of a flow equalization plate, a throttling orifice, an air guide grille, a rectifier grille, an adjustable damper, or a sliding plate throttling component. The flow equalization component 5 is disposed between the distribution chamber 4 and the downstream air intake section, preferably installed at the air outlet of the distribution chamber 4 or at the connection between the distribution chamber 4 and the downstream air intake section, so that the airflow entering the downstream air intake section undergoes at least one of rectification and throttling treatment through the flow equalization component 5.

[0038] In this embodiment, the flow equalization plate can be a plate-shaped member with an array of through holes and / or an array of slits; the throttling orifice can be a plate-shaped member with throttling orifices in a local area; the air guide or rectifier can be a grid member with multiple parallel guide vanes; the adjustable damper or sliding plate throttling element can be a movable member capable of changing the effective flow area, used to adjust the passing airflow when needed. The flow equalization element 5 can be a detachable structure to facilitate replacement of different types of flow equalization elements 5 or maintenance as needed.

[0039] In one possible implementation, the flow equalization component 5 is a flow equalization plate, which is disposed at the air outlet of the distribution cavity 4, located between the distribution cavity 4 and the downstream air intake section. The flow equalization plate is a plate-shaped component with an array of through holes and / or an array of slits, used to rectify or throttle the airflow flowing into the downstream air intake section, thereby improving the uniformity and stability of the airflow.

[0040] The flow distribution plate can be made by processes such as stamping, laser cutting or injection molding. The size, number and arrangement density of the through holes or slits can be adjusted according to the cooling requirements to control the flow area, thereby adapting to different numbers and arrangements of mobile phone mounting components 8 to achieve targeted airflow.

[0041] It is worth noting that the flow distribution plate can be designed to be detachable and installed at the air outlet of distribution chamber 4 by means of screw fixing, clip fixing or embedding, so as to facilitate replacement or maintenance according to different application scenarios during use.

[0042] Please see Figure 1-3 In one possible implementation, the continuous air intake trough 7 is an elongated slot that extends continuously along the length of the hollow crossbeam 2. The continuous air intake trough 7 is connected to the downstream air intake section, thereby forming a continuous air intake opening on the lower side of the hollow crossbeam 2, allowing multiple slides 9 to take in air within their sliding range.

[0043] In this embodiment, when the mobile phone mounting component 8 slides along the length of the hollow crossbeam 2, the air intake interface on the slide block 9 can maintain docking and communication with the continuous air intake slot 7 so as to obtain airflow supply at different sliding positions.

[0044] The cross-sectional shape of the continuous air intake slot 7 can be rectangular, trapezoidal, or other shapes suitable for air guidance and sealing. To form a stable sliding seal with the sealing ring around the air intake interface, a guide groove and / or pressing edge structure that mates with the sealing ring can be provided at the edge of the slot to reduce air leakage and improve the sealing effect.

[0045] Please see Figure 1-3 In one possible implementation, the sealing ring is at least one of an O-ring, a foam sealing ring, or a lip sealing ring. The sealing ring is disposed around the air intake interface of the slide 9 and fits against the edge of the groove of the continuous air intake groove 7 to form a sliding sealing fit, thereby maintaining the sealed communication between the air intake interface and the continuous air intake groove 7 during the sliding of the slide 9 along the hollow crossbeam 2.

[0046] In this embodiment, the O-ring can be a ring-shaped elastomer seal; the foam seal can be a foam ring-shaped seal with elastic resilience; and the lip seal can be an elastomer seal with a lip sealing edge. One or more of the above-mentioned seal types can be selected according to the sealing requirements and sliding conditions.

[0047] The sealing ring can be made of silicone, rubber or high-density foam or a combination thereof, and can be selected according to the ambient temperature, sliding frequency and durability requirements.

[0048] Please see Figure 1-3 In one possible implementation, the hollow crossbeam 2 is provided with a guide structure that extends along the length of the hollow crossbeam 2. The guide structure is a guide rail or a guide groove. The slide block 9 is configured to cooperate with the guide structure to enable the slide block 9 to slide along the length of the hollow crossbeam 2 and to limit the displacement of the slide block 9 in the direction perpendicular to the length.

[0049] In this embodiment, the guide rail can be a raised strip structure set on the surface of the hollow beam 2, and the bottom of the slide 9 is provided with a guide groove that cooperates with the guide rail to form a guide support; or, the guide groove is set on the surface or inside of the hollow beam 2, and the bottom of the slide 9 is provided with a raised guide part that cooperates with the guide groove, and the raised guide part is inserted into the guide groove to achieve guidance and limitation.

[0050] By cooperating with the guide structure, the slide 9 can maintain stable sliding when adjusting its position and reduce deflection during the sliding process.

[0051] Please see Figure 1-2 In one possible implementation, the air outlet of the air guide cover 10 consists of multiple air outlet holes, forming an air outlet array facing the heat dissipation area on the back of the mobile phone, so as to direct the airflow to the heat dissipation area on the back of the mobile phone.

[0052] The air vent array can be configured according to the size and heat-generating parts of different mobile phones. The air vents can be round, elongated, or slit-shaped, and can be arranged in a regular or irregular manner. By setting the diameter, number, density, and position of the air vents, the airflow distribution range can be adjusted to ensure that the airflow covers the main heat-generating areas of the mobile phone.

[0053] The air guide cover 10 can be integrally formed with the slide 9, or it can be a separate structure. When the separate structure is adopted, the air guide cover 10 and the slide 9 can be fixed by snap-fit ​​connection, screw connection or plug-in connection, so as to facilitate installation, disassembly or replacement.

[0054] Please see Figure 1-3 In one possible implementation, the support body 1 also includes a column, which is a telescopic structure used to adjust the height of the hollow crossbeam 2 to adapt to the operating needs of different users or the layout requirements of different installation environments.

[0055] The support column can adopt a sleeve-type or sliding rod-type telescopic structure. The height can be adjusted and fixed by means of threaded locking, buckle positioning, or spring pin limiting between the outer tube and the inner tube. By adjusting the length of the support column, the position of the crossbeam can be raised and lowered within a certain height range to meet various application scenarios such as standing live broadcast, seated shooting, or desktop setting.

[0056] This structure simplifies the adaptation process of the overall bracket, improves the ergonomic fit of the equipment, and also allows for flexible adjustment of the crossbeam position in environments with limited space or complex backgrounds, increasing the freedom of composition and operational comfort of the live broadcast. Anti-slip pads, casters, or counterweights can be added to the bottom of the column to enhance the stability and portability of the bracket.

[0057] In this embodiment, the fan can be an axial flow fan or a turbine fan; the hollow crossbeam 2 can be made of metal or engineering plastic to balance structural strength and lightweight; the sealing ring can be an O-ring, foam sealing ring or lip sealing ring to adapt to different sealing requirements; the slide 9 achieves stable sliding through guide rails or guide grooves; the air outlet of the air guide shroud 10 can be an array of multiple air outlet holes to adapt to different mobile phone sizes and improve airflow uniformity.
