Description

Technical Field

[0001] This utility model belongs to the technical field of conference devices, specifically relating to a foldable wireless audio and video conferencing device. Background Technology

[0002] With the rapid development of technology, intelligent wireless audio and video transceivers are increasingly widely used in various fields, from everyday video shooting and conferencing systems to security monitoring and vehicle imaging, highlighting their growing importance. The rise of the short video industry has further intensified the demand for these devices. However, existing intelligent wireless audio and video transceivers suffer from several technical shortcomings. Regarding power supply, many devices heavily rely on external power sources. For example, some audio and video transceivers based on traditional wireless technologies (such as the common Wi-Fi technology based on the IEEE 802.11 standard) must be connected to AC power via a power cord to function properly. This renders them unusable in locations without external power, such as field maintenance or emergency repairs, or in scenarios requiring frequent relocation of equipment, significantly limiting their scope and flexibility.

[0003] From a structural design perspective, the connection method between the video shooting pole and the main unit has significant drawbacks. Most existing products use a fixed connection between the video shooting pole and the main unit. Taking common video aids as an example, the bracket and transmitter are usually fixed, resulting in the device occupying a large space during storage and transportation, making it extremely inconvenient to carry. In practical use, especially in spaces with limited capacity, such as small conference rooms or vehicles, this fixed structure causes numerous problems. It not only requires a large operating space but may also prevent the device from being properly deployed for shooting or signal transmission / reception due to space constraints. Furthermore, the shooting pole is top-heavy during use. Since the top of the shooting pole typically houses the camera, audio / video transmitter, and other equipment, these components have considerable weight, while the shooting pole itself and the connected main unit are relatively light, resulting in a high center of gravity. In actual operation, such as shooting landscapes outdoors or taking meeting minutes indoors, the device is easily unstable due to the unstable center of gravity, and may even tip over. This not only affects normal shooting, causing image shake and interruption, but may also damage the device from impacts, increasing user risks and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a foldable wireless audio and video conferencing device to solve the following technical problems of existing wireless audio and video conferencing devices: First, the power supply is inflexible, mostly relying on external power, making it difficult to use stably in scenarios without external power or when frequent movement is required; second, the video shooting pole is fixedly connected to the main unit and cannot be folded, resulting in a large space occupation during storage, transportation and use, and poor portability; third, when using the shooting pole, due to the weight of the top device and the high center of gravity, it is prone to top-heavy operation, causing the device to be unstable or even tip over, affecting shooting and potentially damaging the equipment.

[0005] To address the above technical problems, this utility model discloses a foldable wireless audio and video conferencing device, including a housing and a shooting pole assembly. A functional component is fixedly installed in the internal cavity of the housing. The shooting pole assembly is folded and unfolded through the rotational cooperation between a pivot assembly fixed on the shooting pole assembly and a connecting bracket fixedly installed on the housing. The housing has a power socket and an HDMI socket. The functional component includes a battery, which is fixedly installed on a weighted iron and located at the bottom of the internal cavity of the housing.

[0006] Preferably, the housing includes a front shell located at the top of the housing and a bottom shell fixed to the bottom of the housing, the front shell covering the housing on the side of the housing.

[0007] Preferably, the weight has an upwardly protruding fixing post, and the battery is fixed to the weight by the fixing post.

[0008] Preferably, the functional component includes a functional motherboard, and a shock-absorbing strip is provided between the functional motherboard and the battery.

[0009] Preferably, the main board is equipped with a small mic board, a function button light board, and a built-in antenna module. A fixing part is provided below the function button light board. The fixing part extends downward and then bends inward at a right angle. The fixing position formed by the fixing part is used to fix and connect with the battery.

[0010] Preferably, a heat sink is provided above the processor area of ​​the functional motherboard, and thermally conductive silicone is provided between the heat sink and the functional motherboard.

[0011] Preferably, the shooting stick assembly includes a front shell, a camera module, and a rear shell, the front shell and the rear shell being combined to form a shooting stick housing, the camera module being fixedly installed in the cavity of the shooting stick housing, and the front shell having a camera shooting port.

[0012] Preferably, the rear shell is opposite to the front shell of the outer shell, and the rear shell is in contact with the front shell when folded. The camera module has a wide-angle lens. The connecting bracket is fixedly installed on the edge of the outer shell adjacent to the front shell.

[0013] Preferably, the rotating shaft assembly includes a rotating shaft and a rotating shaft fixing member, wherein the rotating shaft fixing member is fixed to the inner side of the rear shell by a screw fastener engaging with a first screw hole.

[0014] Preferably, the shaft of the rotating shaft passes through the shaft hole of the bearing seat on the connecting bracket, and the other end of the rotating shaft is fixedly connected to the second screw hole of the rotating shaft fixing member, wherein the axes of the first screw hole and the second screw hole are perpendicular to each other.

[0015] Compared with the prior art, the beneficial effects obtained by this utility model are: This utility model discloses a foldable wireless audio and video conferencing device. The transmitter device includes a housing and a shooting pole assembly. A functional component is fixedly installed in the internal cavity of the housing. The shooting pole assembly is folded and unfolded by rotating a pivot assembly fixed on the shooting pole assembly and a connecting bracket fixedly installed on the housing. The housing has a power socket. The functional component includes a battery, which is fixedly installed on a weighted iron and located at the bottom of the internal cavity of the housing.

[0016] The power socket on the device casing can be connected to an external power source, while the battery in the functional components can provide built-in power. The two work together to solve the problem of existing devices relying on external power sources or having insufficient battery life. This allows the device to work stably in fixed scenarios with external power sources, as well as in environments without external power sources, such as in the field or on the move. This greatly expands the applicability of the device and meets the diverse power needs of users in different scenarios.

[0017] In terms of structural portability, the shooting stick assembly rotates with the connecting bracket on the outer shell via a hinge assembly, enabling the shooting stick and main unit to fold together. When folded, the rear shell of the shooting stick assembly contacts the front shell of the main shell, significantly reducing the overall size of the device. This design effectively solves the problem of traditional devices occupying a large amount of space during storage, transportation, and use due to the fixed connection between the shooting stick and the main unit, making the device more portable and allowing for flexible use in space-constrained environments, thus significantly improving its portability.

[0018] In terms of stability, the battery in the functional components is fixedly mounted on a weighted iron, which is located at the bottom of the internal cavity of the casing. This weighted iron increases the weight at the bottom of the device, lowering the overall center of gravity and effectively solving the top-heavy problem that occurs when using the shooting stick due to the weight of the top component. This ensures the device can be placed stably during use, reducing the risk of tipping over. It not only prevents interruptions to shooting due to tipping but also reduces the possibility of equipment damage and extends the device's lifespan.

[0019] Furthermore, the transmitter can connect to input devices via multiple interfaces, directly transmitting signals to the playback terminal or transmitting wireless signals via its built-in antenna. The receiver receives signals via an external antenna and transmits them to the display terminal. This flexible signal transmission method eliminates the reliance on numerous power and signal cables found in traditional devices, making operation simple and aesthetically pleasing. Simultaneously, the shooting stick allows manual adjustment of the camera's tilt angle up to 90°. Combined with the camera's wide-angle function and shooting port setting, it fully meets users' shooting needs, further enhancing user convenience. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 3 This embodiment discloses a foldable wireless audio and video conferencing device. The specific structure and assembly relationship of the transmitter device are as follows: The transmitter device mainly consists of a housing 1, a shooting rod assembly 2, and a functional component 3. The housing 1 serves as the main supporting structure of the device, and its internal cavity provides installation space for the functional component 3. The shooting rod assembly 2 rotates with the connecting bracket 25 on the housing 1 via a pivot assembly 24, enabling folding and unfolding operations. The functional component 3 integrates the core electrical functions of the device, ensuring the processing and transmission of audio and video.

[0026] The outer casing 1 consists of a shell 11 surrounding the sides, a top shell 12, and a bottom shell 13. The top shell 12 is located on top of the outer casing 1, covering the side shell 11. The bottom shell 13 is fixed to the bottom of the shell 11. The three are tightly connected by screws or snap-fit ​​connections to form a closed internal cavity. The outer casing 1 is equipped with a power socket 111, an HDMI socket, a Type-C connector, and a USB port. The power socket 111 is used for external power supply, while the HDMI socket, Type-C connector, and USB port are used for audio and video signal transmission. The connecting bracket 25 is fixedly installed on the edge of the adjacent edge of the shell 11 and the top shell 12 of the outer casing 1 by four fastening screws, providing a support point for the rotation of the shooting stick assembly 2.

[0027] The shooting stick assembly 2 includes a front shell 21, a camera module 22, a rear shell 23, and a hinge assembly 24. The front shell 21 and the rear shell 23 are combined with clips and screws to form the shooting stick housing. The camera module 22 is fixedly installed in the cavity of the shooting stick housing. The camera shooting port 211 on the front shell 21 provides the shooting field of view for the camera module 22, and the camera module 22 has a wide-angle function, which can expand the shooting range.

[0028] The rotating shaft assembly 24 consists of a rotating shaft 241 and a rotating shaft fixing member 242. The first screw hole 2421 of the rotating shaft fixing member 242 is fixed to the inner side of the rear shell 23 by screw fasteners. One end of the rotating shaft 241 passes through the shaft hole of the bearing seat 251 on the connecting bracket 25, and the other end of the rotating shaft 241 is fixedly connected to the second screw hole 2422 of the rotating shaft fixing member 242, and the axes of the first screw hole 2421 and the second screw hole 2422 are perpendicular to each other. This structural design allows the shooting stick assembly 2 to rotate relative to the outer shell 1 with the rotating shaft 241 as the central axis, thereby realizing folding and unfolding. In the folded state, the rear shell 23 contacts the front shell 12 of the outer shell 1, which greatly reduces the overall volume of the device and avoids the shooting stick assembly 2 being obstructed by the field of view by the outer shell 1 during the angle adjustment shooting process, thus allowing for a larger actual adjustment angle.

[0029] The shooting stick assembly 2 allows manual adjustment of the camera's tilt angle, with a maximum adjustment angle of 90°. The transmitter's camera also features a wide-angle function, maximizing the user's shooting needs.

[0030] The functional component 3 includes a mainboard 31, a battery 32, and a weight 321. The battery 32 is fixedly mounted on the weight 321, which is located at the bottom of the internal cavity of the outer casing 1. By increasing the weight at the bottom of the device, the overall center of gravity is lowered, effectively solving the problem of the shooting stick being top-heavy during use. The weight 321 has an upwardly protruding fixing post 3211, through which the battery 32 is securely connected to the weight 321.

[0031] A shock-absorbing strip 322, made of EVA foam, is provided between the main board 31 and the battery 32 to reduce vibration transmission between them and protect circuit components. A microphone board 314, a function button light board 313, and a built-in antenna module are fixed on the main board 31. A fixing part 3131 is located below the function button light board 313, extending downwards and then bending inwards at a right angle to form a fixing position for fixed connection with the battery 32, further enhancing the stability of the internal structure of the functional component 3. A function button panel is provided on the faceplate 12, which cooperates with the function button light board 313 to distinguish the start and stop of related functions.

[0032] A heat sink 311 is provided above the processor area of ​​the functional motherboard 31. Thermally conductive silicone 312 is provided between the heat sink 311 and the functional motherboard 31. The heat generated by the processor during operation is conducted to the heat sink 311 through the thermally conductive silicone 312, thereby achieving efficient heat dissipation and ensuring stable operation of the device.

[0033] In addition, the power socket 111 on the outer casing 1 can be connected to an external power source, while the battery 32 in the functional component 3 provides a built-in power source. The combination of the two enables the device to be used with or without an external power source, thus improving the flexibility of the device.

[0034] The transmitter device can be connected to other input devices such as computers via TYPE-C and HDMI connectors, and the processed audio, video and image signals can be directly displayed on the playback terminal. Since the transmitter component has its own battery, it can also convert the collected audio, video and image information into wireless signals and transmit them through the built-in antenna on the functional motherboard 31 without using TYPE-C and HDMI connectors.

[0035] Meanwhile, the corresponding receiver device can receive the wireless signal transmitted by the transmitter device through an external antenna, and then input the audio, video and image signals to the display or playback terminal through the TYPE-C / USB / HDMI interface.

[0036] The above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments, and many similar modifications are possible. All variations that can be directly derived or conceived by those skilled in the art from the content disclosed in this utility model should be considered within the scope of protection of this utility model.
