Description
Technical Field
[0001] This utility model belongs to the field of electronic information equipment, and in particular relates to a multi-interface Thunderbolt desktop expansion dock. Background Technology
[0002] Smartphones, tablets, and laptops have become the common combination for mobile work. In some application scenarios, such as live monitoring, stock trading, and simultaneous multi-party communication, users need to pay attention to information displayed on multiple screens at the same time for comprehensive analysis and judgment. Since laptop PCs typically have four or five general I / O ports, after connecting a mouse, keyboard, and flash storage drive, there is almost only one spare I / O port for connecting other external display devices, making it impossible to connect multiple display devices.
[0003] Most laptop PCs only have USB and HDMI ports as their common I / O ports. These ports, in addition to basic bit stream transmission, do not have enhanced power output capabilities and cannot charge connected terminal display devices (such as tablets and mobile phones) at high speed. As a result, these terminal devices need to be connected to a power source through an adapter to charge, which will cause too many wires during use. This will cause interference when using a combination of smartphones, tablets and laptop PCs placed on a desktop, and will take up office space. Utility Model Content

[0020] Please refer to Figure 1-4 A multi-interface Thunderbolt desktop docking station is composed of two parts: a shell and a circuit board assembly. The shell includes an annular inner shell 100 and a first U-shaped shell 101 and a second U-shaped shell 102 fixed around the annular inner shell 100. A front cover 600 and a rear cover 700 are snapped onto both sides of the shell. The circuit board assembly is disposed inside the shell. The circuit board assembly includes a support member 200, a positioning member 300, an upper circuit board 501, a lower circuit board 500, and a heat dissipation component 400. The support member 200 is fixed inside the annular inner shell 100, the positioning member 300 is fixed on the support member 200, the upper circuit board 501 and the lower circuit board 500 are fixed inside the positioning member 300, and the heat dissipation component 400 is fixed on the upper circuit board 501. The upper circuit board 501 and the lower circuit board 500 are electrically connected.
[0021] In this embodiment, the annular inner shell 100 and the first U-shaped shell 101 and the second U-shaped shell 102 fixed around the annular inner shell 100, with the front cover 600 and the rear cover 700 snapped onto both sides of the outer shell, provide a closed protective space for the circuit board assembly of the expansion dock to be placed therein. The support member 200 provides a base support for the upper circuit board 501, the lower circuit board 500 and the positioning member 300 to ensure that they can be set up stably. The positioning member 300 protects the upper circuit board 501 and the lower circuit board 500 through the protective plates 301 on both sides to prevent damage to the circuit board assembly in the event of falling or external impact.
[0022] Furthermore, an upper flash display bar 104 is provided on the upper part of the annular inner shell 100 between the first U-shaped shell 101 and the second U-shaped shell 102. The upper flash display bar 104 is electrically connected to the controller 107. A lower flash display bar 103 is provided on the lower part of the annular inner shell 100 between the first U-shaped shell 101 and the second U-shaped shell 102. Both the upper flash display bar 104 and the lower flash display bar 103 are provided with buckles 109. The upper and lower edges of the annular inner shell 100 are designed with latches 105.
[0023] In this embodiment, by setting the upper flash display bar 104 and the lower flash display bar 103, the entertainment value of the docking station can be enhanced in a low-light environment. The controller 107 is specifically designed to control the opening and closing of the flash display bar and the color change. The buckle 109 is used to fix the flash display bar to the upper and lower surfaces of the annular inner shell 100. The latch 105 cooperates with the fixing of the front cover 600 and the rear cover 700.
[0024] Furthermore, strip-shaped pieces 106 are fixed at both ends of the bottom of the annular inner shell 100, and a fixing groove is formed between the two strip-shaped pieces 106. Several through holes are designed at the bottom and top of the annular inner shell 100. The buckle 109 fixes the upper flash display strip 104 and the lower flash display strip 103 to the annular inner shell 100 through the through holes. The annular inner shell 100 is fixedly connected to the first U-shaped shell 101 and the second U-shaped shell 102 by fasteners 108.
[0025] In this embodiment, the function of the fixing groove is to snap the two ends of the support plate 200 to provide a base for the entire circuit board assembly. The fasteners 108 pass through the through holes at the bottom and top of the annular inner shell 100 to fix the annular inner shell 100 to the first U-shaped shell 101 and the second U-shaped shell 102. Four fasteners 108 are provided.
[0026] Furthermore, the support member 200 is horizontally snapped into the fixing groove formed between the two strip members 106. The support member 200 has long fixing posts 201 at its four corners. The long fixing posts 201 pass through the central hole of the snap post 511 and are fixedly connected to the upper circuit board 501. After passing through the fixing ears 402 at the four corners of the heat dissipation assembly 400, they are fixedly connected to the heat dissipation assembly 400. The positioning member 300 is fixedly connected to the support member 200 by screws and screw holes to fix the position of the upper circuit board 501 and the lower circuit board 500. The positioning member 300 has protective plates 301 at both ends.
[0027] In this embodiment, the upper circuit board 501 and the lower circuit board 500 are electrically connected and also fixedly connected by connecting posts.
[0028] Furthermore, the upper circuit board 501 has an audio module 505, a lightning module 510, and a switch module 509 at its front end, and a power module 502, a DP module 503, and an HDMI module 504 at its rear end. The lower circuit board 500 has a USB-C module 506, a first USB module 507, and a TF module 508 at its front end, and an SD module 514, an RJ45 module 513, and a second USB module 512 at its rear end.
[0029] In this embodiment, two Thunderbolt modules 510 are provided. The left one can output a maximum power of 15W, and the right one can output a maximum power of 85W. The bitstream switching speed can reach 40Gbps. Thunderbolt modules 510 can quickly charge mobile phones, tablets, and laptops connected to the docking station, enhancing battery life and enabling ultra-high-speed file transfer between connected devices. One USB-C module 506 is provided, supporting PD fast charging and outputting a maximum power of 20W. The bitstream switching speed can reach 10Gbps. The USB-C module 506 can also function as a Thunderbolt module 510. One first USB module 507 and two second USB modules 512 are provided, located on the front and back of the docking station respectively. These three USB modules can basically meet the needs of connecting a mouse and keyboard, with one module available as a backup. One SD module 514 and one TF module 508 are provided, offering convenient hot-swapping and portability. One RJ45 module 513 connects the docking station to the Ethernet, allowing internet access for tablets and laptops via a Thunderbolt module, USB-C module, or USB module using a corresponding data cable. One DP module 503 and one HDMI module 504 are also included. Since the Thunderbolt module 510 and USB-C module 506 enable fast charging for peripherals, separate power adapters are no longer needed, avoiding the interference and space-consuming issues caused by excessive wiring when using multiple devices together. This docking station features a variety of I / O interfaces, allowing for easy connection of multiple peripherals and providing convenience for multi-device office work.
[0030] Furthermore, the heat dissipation assembly 400 is designed with an array of heat sinks 401 and fixed ears 402 at the four corners, and an annular hole 403 in the middle to facilitate the controller 107 to pass through and be electrically connected to the upper circuit board 501.
[0031] Furthermore, the front cover 600 is fixed to the slot 105 by the first locking block 601, and the rear cover 700 is fixed to the slot 105 by the second locking block 701.
