Description

Technical Field

[0001] This utility model relates to the field of multi-screen extender technology, specifically a point-to-point multi-screen extender for 8K input and 4K output. Background Technology

[0002] A multi-screen extender is an intelligent device used to enable connection and collaborative work between multiple screen display devices. It typically connects to a main device via interfaces such as HDMI and USB, and transmits the screen signal from the main device to multiple display terminals. Its core function is to achieve multi-screen display, which can display the same screen simultaneously on multiple screens, and also achieve multi-screen extension function, extending the desktop of the main device to multiple screens, so that users can operate different applications on different screens, greatly improving work efficiency.

[0003] The 8K input, 4K output point-to-point multi-screen extender is a professional display device that can receive 8K resolution high-definition signal input and then output the signal to multiple display terminals in 4K resolution. The core advantage of this device is that it can efficiently process high-resolution signals and ensure the stability of signal transmission and the clarity of image quality through point-to-point technology. It supports multi-screen output and can simultaneously display the image from the same signal source on multiple 4K screens, meeting the needs of scenarios such as large-scale conferences, high-end teaching, and professional exhibitions.

[0004] Multi-screen extenders can dissipate heat through air convection using their own ventilation holes. However, during large outdoor performances or live broadcasts of events in summer, the hot weather and high external temperature result in a small temperature difference between the outside and inside the device. This small temperature difference weakens the air convection and significantly reduces heat dissipation efficiency. Consequently, heat accumulates inside the device due to its inability to dissipate quickly. This heat accumulation slows down the operation of internal chips and circuits, reducing signal processing speed and causing image delays or stuttering. In severe cases, it can even damage internal chips and circuits, affecting the device's performance and lifespan. Therefore, to address these issues, a point-to-point multi-screen extender with 8K input and 4K output is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a point-to-point multi-screen extender for 8K input and 4K output. It can dissipate heat normally in the normal environment by means of air convection, and can expand the heat dissipation range and enhance air flow in high-temperature environments by means of a moving cooling fan. This avoids the impact of heat accumulation inside the device on internal chips and circuits, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A point-to-point multi-screen extender for 8K input and 4K output includes a body 1. Symmetrical heat dissipation slots 2 are provided on the left and right sides of the body 1. Heat dissipation components 3 are symmetrically arranged on the left and right sides of the body 1. A dustproof component 4 is provided on the side of the heat dissipation component 3 away from the body 1. The heat dissipation component 3 includes a heat dissipation box 31. A heat-conducting slot 32 matching the specifications of the heat dissipation slots 2 is provided on the heat-conducting slot 31. A heat dissipation fan 33 is provided inside the heat-conducting slot 32. The upper and lower ends of the heat dissipation fan 33 are in contact with the inner top and bottom walls of the heat dissipation slot 2. An electric push rod 37 is provided on the rear side of the heat dissipation fan 33. The heat dissipation box 31 and the body 1 are connected by bolts 38.

[0028] As a further implementation of this solution, the inner top and bottom walls of the heat conduction channel 32 are symmetrically provided with movable slots 34. The upper and lower ends of the heat dissipation fan 33 are symmetrically and fixedly connected with movable blocks 35. The movable blocks 35 and the movable slots 34 are matched in specifications. The movable blocks 35 are set in the movable slots 34. The heat dissipation fan 33 is slidably connected to the movable slots 34 through the movable blocks 35. The center of the rear wall of the heat dissipation channel 2 is provided with a drive slot 36. The inner end face of the drive slot 36 is fixedly connected with an electric push rod 37. The output end of the electric push rod 37 is fixedly connected to the rear end of the heat dissipation fan 33. The heat dissipation component 3 can expand the heat dissipation range and enhance air flow in high temperature environment through the movable heat dissipation fan 33, so as to avoid the internal chips and circuits being affected by heat accumulation inside the body 1.

[0029] As a further implementation of this solution, the dustproof component 4 includes a dustproof plate 41. The cross-sectional specifications of the dustproof plate 41 are consistent with those of the body 1 and the heat sink 31. The dustproof plate 41 has a heat dissipation channel 42 that matches the specifications of the heat dissipation channel 2 and the heat conduction channel 32. A dustproof filter 43 is fixedly connected in the heat dissipation channel 42. A first magnetic frame 5 is fixedly connected to the frame of the left and right side walls of the body 1 and the frame of the side wall of the heat sink 31 away from the body 1. A second magnetic frame 6 that matches the specifications of the first magnetic frame 5 and is corresponding in position is fixedly connected to the frame of the side wall of the dustproof plate 41 close to the body 1. The dustproof component 4 can provide good dustproof capability for the body 1 when the heat dissipation component 3 is not installed, and can provide good dustproof capability for the heat dissipation component 3 and the body 1 when the heat dissipation component 3 is installed, preventing external dust from entering the heat sink 31 and the body 1 through the heat conduction channel 32 and the heat dissipation channel 2 and affecting the internal components of the heat sink 31 and the body 1.

[0030] Workflow: First, all electrical appliances are powered on and connected to an external controller. The main unit 1 can receive 8K resolution high-definition signal input and then outputs the signal at 4K resolution to multiple display terminals. Point-to-point technology ensures the stability of signal transmission and the clarity of image quality. In non-high-temperature environments, there is no need to install the heat dissipation component 3; the heat dissipation channel 2 provides basic air convection cooling for the main unit 1. The dustproof plate 41 in the dustproof component 4 can be installed on the left and right ends of the main unit 1 through the magnetic attraction between the second magnetic frame 6 and the first magnetic frame 5. The heat dissipation channel 42 ensures air convection flow through the heat dissipation channel 2, and the dust filter 43 provides cooling for the main unit. 1. Provides good dustproof capability, preventing external dust from entering the body 1 through the heat dissipation channel 2 and affecting the internal chips and circuits of the body 1. In summer outdoor or other high-temperature environments, heat dissipation components 3 need to be installed to ensure the heat dissipation effect of the body 1. First, the heat dissipation box 31 is placed close to the left and right ends of the body 1 and connected to the left and right ends of the body 1 with bolts 38. Then, the dustproof plate 41 is installed on the outside of the heat dissipation box 31 by the magnetic attraction between the second magnetic frame 6 and the first magnetic frame 5 on the side wall of the heat dissipation box 31. The heat dissipation channel 42, the heat conduction channel 32 and the heat dissipation channel 2 ensure the overall heat dissipation flow, and the dustproof filter 43 provides heat dissipation for the heat dissipation assembly. Component 3 and body 1 provide good dust protection, preventing external dust from entering the heat sink 31 and body 1 through the heat conduction channel 32 and heat dissipation channel 2, thus preventing it from affecting the internal components of the heat sink 31 and body 1. During heat dissipation, the cooling fan 33 and the electric push rod 37 in the drive slot 36 are activated. The cooling fan 33 can enhance airflow and improve the heat dissipation effect inside the body 1. The reciprocating electric push rod 37 acts on the cooling fan 33, causing the cooling fan 33 to slide back and forth in the movable slot 34 through the movable block 35. The reciprocating motion of the cooling fan 33 can continuously change the airflow direction, making the airflow inside the body 1 more sufficient and uniform. The heat dissipation is even and can cover a larger heat dissipation area, avoiding the problem of insufficient local heat dissipation. The two heat dissipation fans 33 can be set to blow in the same direction, so that the air enters the body 1 from one direction, takes away the heat, and quickly exhausts the heat along this direction. It is worth mentioning that although the heat dissipation component 3 can still be installed normally to improve the heat dissipation effect in non-high temperature environments, if the air convection of the body 1 through the heat dissipation channel 2 can meet the heat dissipation requirements in non-high temperature environments, installing the heat dissipation component 3 will increase the overall space to a certain extent and add an extra installation process and energy consumption. Therefore, it is better to install the heat dissipation component 3 in high temperature environments.
