Description

Technical Field

[0001] This utility model relates to the field of signal transmission technology, and in particular to an HDMI wireless extender. Background Technology

[0002] High-definition multimedia interface (HDMI) is a fully digital video and audio transmission interface that has been widely used in various audio and video devices such as TVs, computers, game consoles, and DVD players. However, in practical applications, due to the limitation of HDMI signal transmission distance, traditional HDMI cables often cannot meet the requirements when the distance between the signal source and the display device is far.

[0003] To overcome the limitations of traditional HDMI cable transmission distance and the shortcomings of wired extenders, wireless HDMI extenders have emerged. A wireless HDMI extender is a device that wirelessly transmits audio and video signals from the signal source device to a remote display device. Specifically, the wireless extender at the transmitting end is connected to the host, while the wireless extender at the receiving end is connected to the display device.

[0004] However, existing wireless extenders for the transmitting end often lack space after being connected to the host, making it impossible to place them on a desktop like the wireless extender for the receiving end. Therefore, there is a need for a wireless extender for the transmitting end that can be easily installed and placed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing wireless extenders, such as the lack of space to place the transmitter after it is connected to the host, and the inability to place it on a desktop like the receiver wireless extender. Therefore, this invention proposes an HDMI wireless extender.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An HDMI wireless extender includes a wireless extender body, the wireless extender body including a lower housing and an upper housing disposed on top of the lower housing;

[0008] An installation mechanism is used to fix the lower outer shell. The installation mechanism is located on one side of the lower outer shell and includes a fixing seat and a buckle plate. The fixing seat is fixedly located on one side of the lower outer shell. A connecting seat is rotatably provided on one side of the fixing seat, and the buckle plate is located on one side of the connecting seat. A polygonal cavity is opened inside the connecting seat. A polygonal rod is slidably arranged inside the polygonal cavity, and one end of the polygonal rod slidably extends into the interior of the fixing seat. A side cavity is opened inside the connecting seat and is connected to the polygonal cavity. An insert plate is fixedly provided on the top of the buckle plate, and one end of the insert plate slidably penetrates into the interior of the side cavity. A side plate is fixedly provided on the outer wall of the polygonal rod, and the side plate is located inside the side cavity. An insert rod is fixedly provided on one side of the side plate, and the insert rod slidably penetrates the insert plate.

[0009] In one possible design, the wireless extender body also includes two antennas respectively disposed at both ends of one side of the lower housing.

[0010] In one possible design, the wireless extender also includes an input connector, an output connector, and a power connector located on one side of the lower housing, the interior of which is fitted with a circuit board.

[0011] In one possible design, the mounting mechanism further includes a limiting rod fixedly disposed inside the polygonal cavity. The polygonal rod is slidably sleeved on the outer wall of the limiting rod. A compression spring is sleeved on the outer wall of the limiting rod, and the two ends of the compression spring are respectively fixedly disposed on one end of the polygonal rod and one side of the inner wall of the polygonal cavity.

[0012] In one possible design, the mounting mechanism further includes a round rod located on one side of the fixed base, one end of which slides through the fixed base and is fixedly mounted to one end of the polygonal rod.

[0013] In one possible design, a connecting strip is fixedly provided on one side of the upper housing, a sliding opening is provided on the outer wall of the round rod, a through hole is provided on the outer wall of the round rod, and the through hole is connected to one end of the sliding opening, and the connecting strip cooperates with the through hole and the sliding opening.

[0014] In one possible design, rubber pads are provided on the surfaces of the lower and upper outer shells that come into contact with each other.

[0015] In this application, during actual use, the mounting plate is located inside the chassis, and the insert plate on one side of the mounting plate is inserted to the outside of the chassis through the heat dissipation holes. Then, the round rod is pressed down, causing the round rod to move the polygonal rod, which in turn moves the side plate, which in turn moves the insert rod. At this point, the device can be aligned with the insert plate and inserted. Subsequently, the polygonal rod is reset by a compression spring, along with the side plate and the insert rod, so that one end of the insert rod is inserted into the inside of the insert plate, achieving the effect of hanging the device on the outside side of the chassis. This solves the problem of insufficient placement space when existing wireless extenders are connected to the host. Furthermore, by pressing down the round rod, which causes the round rod to move the polygonal rod, allowing one end of the polygonal rod to leave the range of the mounting base, the device can be rotated. The device is designed to be movable, allowing for positional adjustments as needed. Since the length of the insert rod is longer than the length of the polygonal rod inside the mounting base, pressing the round rod to adjust the device's angle does not disconnect the connection between the mounting plate and the device. To secure the upper housing, pressing the round rod moves the connecting strip from the sliding opening into the through hole, releasing the upper housing from its fixed position. Because rubber pads are provided on the contact surfaces of the lower and upper housings, a seal is ensured while preventing the connecting strip from falling directly when inside the through hole; the user must manually remove it. This prevents the upper housing from accidentally falling off when adjusting the angle or disconnecting the mounting plate.

[0016] In this utility model, the HDMI wireless extender, through the buckle plate of the mounting mechanism, can fix the device to the side of the chassis when connected to the host, thereby solving the problem of lack of placement, and can also be angled for easy adjustment by the user;

[0017] In this utility model, the HDMI wireless extender can fix the upper and lower shells through the connecting strip of the installation mechanism, so that when it needs to be disassembled for maintenance, it can be separated quickly and conveniently without the use of additional tools.

[0018] In this invention, the transmitter can be fixedly installed by setting an installation mechanism, allowing it to be suspended to the side of the chassis, thus solving the problem of insufficient placement space. At the same time, installation and disassembly are also very convenient, and users can adjust the position according to their needs. It has the advantages of convenient installation and easy use.

Rubber pads are provided on the contact surfaces of the lower housing 1 and the upper housing 3 to increase the seal between them. Two antennas 2 are respectively disposed at both ends of one side of the lower housing 1 to enhance the transmission effect of wireless signals.

[0029] The lower housing 1 also has an input connector 4, an output connector 5, and a power connector 6 on one side for connecting the HDMI signal source, display device, and power supply. Inside the lower housing 1 is a circuit board for processing the wireless transmission of the HDMI signal.

[0031] This application can be used in the field of signal transmission, or in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figure 2 An improvement upon Embodiment 1: An HDMI wireless extender, applied in the field of signal transmission, includes a mounting mechanism for fixing the lower housing 1, which is located on one side of the lower housing 1. Specifically, the mounting mechanism includes a fixing base 7 and a buckle plate 8, with the fixing base 7 fixedly disposed on one side of the lower housing 1. A connecting base 9 is rotatably disposed on one side of the fixing base 7, and the buckle plate 8 is located on one side of the connecting base 9.

[0034] Reference Figure 3-5 The connecting seat 9 has a polygonal cavity 11 inside, and a polygonal rod 12 is slidably disposed inside the polygonal cavity 11, with one end of the polygonal rod 12 slidably extending into the interior of the fixing seat 7. A limiting rod 14 is located inside the polygonal cavity 11, and the polygonal rod 12 is slidably sleeved on the outer wall of the limiting rod 14. A compression spring 13 is sleeved on the outer wall of the limiting rod 14, and the two ends of the compression spring 13 are respectively fixed to one end of the polygonal rod 12 and one side of the inner wall of the polygonal cavity 11.

[0035] The connecting seat 9 also has a side cavity 15 inside, and the side cavity 15 is connected to the polygonal cavity 11. The top of the buckle plate 8 is fixedly provided with an insert plate 17, and one end of the insert plate 17 slides through the interior of the side cavity 15. The outer wall of the polygonal rod 12 is fixedly provided with a side plate 16, and the side plate 16 is located inside the side cavity 15. One side of the side plate 16 is fixedly provided with an insert rod 18, and the insert rod 18 slides through the insert plate 17.

[0036] Specifically, the buckle plate 8 is located inside the chassis, and the plug plate 17 on one side of the buckle plate 8 is inserted to the outside of the chassis through the heat dissipation hole. Then, the round rod 10 is pressed, the round rod 10 drives the polygonal rod 12 to move, the polygonal rod 12 drives the side plate 16 to move, and the side plate 16 drives the plug rod 18 to move. At this time, the device can be aligned with the plug plate 17 and inserted. Then, the polygonal rod 12 is reset by the compression spring 13, which resets the side plate 16 and the plug rod 18, so that one end of the plug rod 18 is inserted into the inside of the plug plate 17, realizing the effect of hanging the device on the outside side of the chassis. This solves the problem of lack of placement space when the existing wireless extender is connected to the host.

[0037] Furthermore, by pressing down on the round rod 10, the round rod 10 drives the polygonal rod 12 to move, so that when one end of the polygonal rod 12 is out of the range of the fixed seat 7, the equipment can rotate, thereby allowing the position to be adjusted as needed. At the same time, since the length of the insertion rod 18 is longer than the length of the polygonal rod 12 inside the fixed seat 7, when the angle of the equipment is adjusted by pressing down on the round rod 10 normally, the connection between the buckle plate 8 and the equipment will not be released.

[0038] Reference Figure 6 The outer wall of the round rod 10 has a sliding opening 19, and the outer wall of the round rod 10 also has a through hole 20, which is connected to one end of the sliding opening 19. A connecting strip 21 is fixedly provided on one side of the upper outer shell 3, and the connecting strip 21 cooperates with the through hole 20 and the sliding opening 19.

[0039] Specifically, for fixing the upper outer shell 3, by pressing the round rod 10, the connecting strip 21 is moved from the sliding opening 19 into the through hole 20. At this time, the fixing state of the upper outer shell 3 can be released. Since rubber pads are provided on the contact surfaces of the lower outer shell 1 and the upper outer shell 3, the sealing is ensured while the connecting strip 21 will not fall directly when it is inside the through hole 20. The user needs to remove it manually to avoid the upper outer shell 3 from accidentally falling off when adjusting the angle and disconnecting the buckle plate 8.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of antenna 2, input connector 4, output connector 6, power connector 6 and circuit board are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
