Description

Technical Field

[0001] This utility model relates to a transmitter, specifically a multi-channel audio and video synchronous network transmitter, belonging to the field of network transmitter technology. Background Technology

[0002] An audio / video signal network transmitter is a device specifically designed to transmit audio and video signals over a network. It encodes audio and video signals from various signal sources (such as computers, high-definition playback devices, etc.) and transmits them via a network (such as a local area network, wide area network, or the Internet) to remote devices (such as high-definition televisions, high-definition projectors, etc.) for decoding and playback.

[0003] Audio and video signal network transmission requires the use of audio and video signal network transmitters. However, existing audio and video signal network transmitters lack good heat dissipation and cooling mechanisms in actual use, making it difficult to dissipate the heat generated by the main body of the audio and video signal network transmitter, resulting in generally poor stability during actual operation.

[0004] A Chinese patent (publication number: CN213305558U) discloses an audio and video signal network transmitter, which is equipped with a good heat dissipation and cooling mechanism for the main body of the audio and video signal network transmitter. In practice, the heat of the main body of the audio and video signal network transmitter is easily dissipated, and the actual working stability is good.

[0005] Although the device uses heat sinks and fans to dissipate heat from the audio and video network transmitter, the actual heat dissipation effect is not ideal. It can only accelerate the airflow outside the casing and achieve heat dissipation through heat exchange. However, in actual operation, the heat generated by the internal modules is often difficult to dissipate quickly. Therefore, a multi-channel audio and video synchronous network transmitter is proposed. Utility Model Content

[0006] In view of this, the present invention provides a multi-channel audio and video synchronous network transmitter to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0007] The technical solution of this utility model embodiment is implemented as follows: a multi-channel audio and video synchronous network transmitter includes a housing, a top cover is installed on the housing, through slots are symmetrically opened on both sides of the housing, a heat dissipation fan is installed on the lower surface of the top cover, and a heat dissipation component is provided on the housing.

[0008] The heat dissipation assembly includes a support mesh, a guide sleeve, a magnetic ring, a mounting cover, an external filter plate, a spring, a fixing base, and a guide rod;

[0009] The guide sleeve is fixedly connected to the outer wall of the housing and corresponds to the position of the through groove. The magnetic ring is fixedly connected to one side of the mounting cover. The outer filter plate is fixedly connected to the inside of the mounting cover. The filter element is installed inside the mounting cover. The guide rod is slidably connected to the inside of the fixing seat. The fixing seat is fixed to the inner side wall of the through groove. The spring is sleeved on the outer side wall of the guide rod. The support net is fixedly connected to one end of the guide rod.

[0010] More preferably, the mounting cover is slidably connected to the inner wall of the guide sleeve and is attracted to the outer wall of the housing by the magnetic ring.

[0011] More preferably, the two ends of the spring abut against the support net and the fixing seat, respectively.

[0012] More preferably, the side of the support mesh away from the guide rod is attached to and pressed against the filter element.

[0013] More preferably, a protective net is fixedly connected to the upper surface of the top cover, and the position of the protective net corresponds to the position of the cooling fan.

[0014] More preferably, a circuit board is mounted on the inner sidewall of the housing.

[0015] More preferably, the circuit board is equipped with an audio / video acquisition module, an audio / video encoding module, a control module, and a network transmission module.

[0016] More preferably, a signal interface is installed on the front surface of the housing, and a power interface is installed on the rear surface of the housing.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] This invention utilizes a cooling fan to allow external air to enter the casing through slots on both sides and then exit from the top, thus achieving heat dissipation. During this process, the air entering the casing is filtered by a filter element to ensure cleanliness and prevent dust and impurities from adhering to the circuit board. After prolonged use, the mounting cover can be pulled out, and a new filter element can be placed inside. The mounting cover is then attached to the casing by a magnetic ring, allowing the filter element to contact the support mesh. Under the action of a spring, deformation and central collapse of the filter element are prevented, ensuring good filtration performance. Compared to existing technologies, this invention achieves efficient heat dissipation by guiding air flow and exhaust within the casing. Furthermore, the magnetic installation design of the heat dissipation component greatly facilitates filter element replacement.

Detailed Implementation

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-5As shown, this utility model embodiment provides a multi-channel audio and video synchronous network transmitter, including a housing 11, a top cover 24 installed on the housing 11, and through slots 12 symmetrically opened on both sides of the housing 11. A cooling fan 25 is installed on the lower surface of the top cover 24. When the cooling fan 25 is started, external air enters the interior from both sides of the housing and then exits from the top. In this process, the air carries away the heat inside the housing 11, thereby effectively realizing the heat dissipation function of the device.

[0030] The housing 11 is provided with a heat dissipation assembly 101, which includes a support mesh 13, a guide sleeve 14, a magnetic ring 16, a mounting cover 17, an external filter plate 18, a spring 20, a fixing seat 21, and a guide rod 22.

[0031] The guide sleeve 14 is fixedly connected to the outer side wall of the housing 11 and corresponds to the position of the through groove 12. The magnetic ring 16 is fixedly connected to one side of the mounting cover 17. The mounting cover 17 is slidably connected to the inner side wall of the guide sleeve 14 and is attracted to the outer side wall of the housing 11 by the magnetic ring 16. Thus, through the attraction of the magnetic ring 16 and the limiting function of the guide sleeve 14, the position of the mounting cover 17 can be precisely defined. In addition, the mounting cover 17 is fixed by magnetic attraction, making it easy to disassemble when needed.

[0032] The external filter plate 18 is fixedly connected to the inside of the mounting cover 17. The inside of the mounting cover 17 is a filter element 19, which is used to filter the air entering the machine to ensure that the air is clean and prevent dust and impurities in the air from adhering to the circuit board.

[0033] The guide rod 22 is slidably connected to the inside of the fixed seat 21, which is fixed to the inner side wall of the through groove 12. The spring 20 is sleeved on the outer side wall of the guide rod 22. The support net 13 is fixedly connected to one end of the guide rod 22. The two ends of the spring 20 abut against the support net 13 and the fixed seat 21 respectively. The side of the support net 13 away from the guide rod 22 is attached to and presses against the filter element 19. Driven by the spring 20, the support net 13 pushes the filter element 19, and the outer filter plate 18 effectively limits the position of the filter element 19, thereby ensuring the stable position of the filter element 19. In addition, under the joint squeezing action of the support net 13 and the outer filter plate 18, the filter element 19 can avoid deformation and central collapse, thereby ensuring the good filtration effect of the filter element 19.

[0034] In one embodiment, a protective net 23 is fixedly connected to the upper surface of the top cover 24. The position of the protective net 23 corresponds to the position of the cooling fan 25. The protective net 23 can prevent the user from accidentally touching the cooling fan 25.

[0035] In one embodiment, a circuit board 31 is installed on the inner wall of the housing 11, and an audio and video acquisition module 32, an audio and video encoding module 33, a control module 34 and a network transmission module 35 are installed on the circuit board 31.

[0036] The audio and video acquisition module 32 is responsible for acquiring raw audio and video signals, including analog and digital signals. When the audio and video signal is an analog signal, it is converted into a digital signal by an analog-to-digital converter for subsequent processing.

[0037] The audio and video encoding module 33 is one of the core components of the audio and video signal network transmitter. The audio and video encoding module 33 uses a specific audio and video compression algorithm to encode the acquired audio and video signals in order to reduce the amount of data and facilitate network transmission.

[0038] Network transmission module 35 is responsible for transmitting the encoded audio and video data through network protocols;

[0039] The control module 34 is responsible for the control and scheduling of the entire device. The control module 34 includes a microprocessor and a memory. By executing specific control algorithms and logic, the control module 34 coordinates and manages various modules such as audio and video acquisition, encoding, transmission and decoding.

[0040] In one embodiment, a signal interface 36 is installed on the front surface of the housing 11, and a power interface 37 is installed on the rear surface of the housing 11. Multiple signal interfaces 36 are provided to support multiple independent inputs and outputs, thereby realizing multi-channel transmission. The signal interfaces 36 are input ports and output ports respectively. A decoding module is provided in the input port, which is responsible for decoding the received audio and video data packets and restoring them into the original audio and video signals for playback devices.

[0041] When this utility model is in operation: it receives audio and video signals through the input port and then sends them to the audio and video acquisition module 32. Subsequently, the audio and video encoding module 33 encodes the acquired audio and video signals using a specific audio and video compression algorithm. Under the control of the control module 34, the network transmission module 35 transmits the encoded audio and video data through the network protocol and then outputs the data through the output port.

[0042] When in operation, the cooling fan 25 operates, and external air enters the interior of the casing 11 through the through slots 12 on both sides of the casing and then exits from the top, thereby achieving the heat dissipation function. During this process, the air entering the casing is filtered by the filter element 19 to ensure that the air is clean and to prevent dust and impurities in the air from adhering to the circuit board.

[0043] After the cooling fan 25 has been used for a long time, the filter element 19 should be replaced according to the actual situation. When replacing, simply pull out the mounting cover 17, and the magnetic ring 16 will separate from the housing 11. At this time, the new filter element 19 can be placed inside the mounting cover 17, and then the mounting cover 17 will be attracted to the housing 11 by the magnetic ring 16. At this time, the filter element 19 will be in contact with the support mesh 13. Under the action of the spring 20, the deformation and collapse of the filter element 19 in the middle can be avoided, thereby ensuring the good filtration effect of the filter element 19.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
