Description

Technical Field

[0001] This application relates to the technical field of docking stations, and in particular to a fast-charging USB-C docking station with integrated flash memory storage and its mounting structure. Background Technology

[0002] A fast-charging USB-C docking station is a hardware device with a USB-C interface at its core, combining the dual core functions of "interface expansion" and "high-power fast charging". While solving the problem of insufficient number of ports for single USB-C interface devices (such as laptops, tablets, and mobile phones), it can provide charging power to the device itself or external devices that far exceeds that of ordinary USB-C interfaces, realizing "expansion and fast charging at the same time", balancing the device's connectivity needs and battery life replenishment needs.

[0003] When in use, it is first connected to the corresponding device (laptop, tablet, mobile phone) through one end, and then the other interfaces are connected to the corresponding external devices as needed. However, in actual use, the docking station only has the functions of data transmission or fast charging, and does not have integrated storage functions. This results in limited functionality during actual use, and the chip will generate heat when processing. In order to improve the heat dissipation effect, ventilation holes are usually opened. However, when not in use, the ventilation holes are easily corroded by moisture. If there are no ventilation holes, the heat dissipation effect will be poor, which will cause inconvenience during use. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a fast-charging USB-C docking station with integrated flash memory storage and its installation structure.

[0005] This application provides a fast-charging USB-C docking station with integrated flash memory storage and its installation structure, which adopts the following technical solution: it includes a PCB board, a TC male connector is fixedly connected to the lower side of the PCB board, a hub chip is fixedly connected to the upper side of the PCB board and located at the center, an inductor module is fixedly connected to the upper side of the PCB board and located to one side of the hub chip, a 9-pin USB-A female connector is fixedly connected to the upper side of the PCB board and located to one side of the inductor module, a 16-pin Type-C female connector is provided on the upper side of the PCB board and located opposite to the TC male connector, and a 24-pin Type-C female connector is fixedly connected to the upper side of the PCB board and located opposite to the 9-pin USB-A female connector.

[0006] A PD protocol chip is fixedly connected to the lower side of the PCB board and at its center. A MOS transistor is fixedly connected to the lower side of the PCB board. A flash memory module is fixedly connected to the lower side of the PCB board and away from the MOS transistor.

[0007] An installation structure for a USB-C docking station further includes a protective mechanism. The protective mechanism includes a base disposed on the underside of a PCB board, a limiting rod fixedly connected to the upper side of the inner wall of the base and cooperating with the PCB board, a connecting cover disposed on the upper side of the PCB board and cooperating with the base, sliding openings on the front and rear sides of the base, movable blocks slidably engaged with the inner walls of the two sliding openings, a sealing plate fixedly connected to the adjacent side of the two movable blocks, a sealing strip fixedly connected to one side of the sealing plate and abutting the sliding opening, and ventilation openings on the front and rear sides of the base.

[0008] Optionally, the upper side of the base is provided with multiple hidden slots, which are respectively engaged with the TC male connector, the 9-pin USB-A female connector, the 16-pin Type-C female connector, and the 24-pin Type-C female connector.

[0009] Optionally, dustproof nets are fixedly connected to the inner walls of both vents, and the vents are fitted together with the sealing plate.

[0010] Optionally, a toggle block is fixedly connected to each of the two movable blocks on opposite sides, and a soft sleeve is fixedly connected to the outer side of each of the two toggle blocks.

[0011] Optionally, the PCB board has multiple limiting holes, which are slidably engaged with multiple limiting rods.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1.

It realizes a multi-functional integration of "fast charging + data + storage", comprehensively meeting users' needs in device connection, fast charging and data storage, and improving the practicality and value of the device.

[0015] 2. By setting up a protective mechanism, the sealing plate in the protective mechanism can slide within the sliding port of the base with the help of a movable block. This allows the movable block to move the sealing plate and sealing strip, thereby controlling the opening and closing of the ventilation port. The ventilation port is opened when in use and closed when not in use, effectively preventing external factors such as dust and moisture from corroding the internal core components, extending the service life of the expansion dock, and preventing dust from entering while ensuring heat dissipation requirements, ensuring that the expansion dock can work stably and reliably in a good environment.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a fast-charging USB-C docking station with integrated flash memory storage and its installation structure.

[0024] Example 1:

[0025] A fast-charging USB-C docking station with integrated flash memory storage includes a PCB board 1. A TC male connector 2 is fixedly connected to the lower side of the PCB board 1. A hub chip 3 is fixedly connected to the upper side of the PCB board 1 and located at the center. An inductor module 4 is fixedly connected to the upper side of the PCB board 1 and located to one side of the hub chip 3. A 9-pin USB-A female connector 5 is fixedly connected to the upper side of the PCB board 1 and located to one side of the inductor module 4. A 16-pin Type-C female connector 6 is provided on the upper side of the PCB board 1 and located opposite to the TC male connector 2. A 24-pin Type-C female connector 7 is fixedly connected to the upper side of the PCB board 1 and located opposite to the 9-pin USB-A female connector 5.

[0026] A PD protocol chip 8 is fixedly connected to the lower side of PCB board 1 and located at the center. A MOSFET 9 is fixedly connected to the lower side of PCB board 1. A flash memory module 10 is fixedly connected to the lower side of PCB board 1 and located away from the MOSFET 9.

[0027] Please see Figure 2 The PCB board 1 has multiple limiting holes 15. The limiting holes 15 can be pre-drilled holes made by the integral casting process. The multiple limiting holes 15 are slidably engaged with multiple limiting rods 112. The multiple limiting holes 15 on the PCB board 1 are slidably engaged with the limiting rods 112. With the help of this sliding engagement, the PCB board 1 can be positioned to ensure that the PCB board 1 is accurately installed in the corresponding position, thus ensuring the accuracy and stability of the overall structure of the docking station.

[0028] Example 2:

[0029] An installation structure for a USB-C docking station further includes a protective mechanism 11. The protective mechanism 11 includes a base 111 disposed on the lower side of a PCB board 1, a limiting rod 112 fixedly connected to the upper side of the inner wall of the base 111 and cooperating with the PCB board, a connecting cover 113 disposed on the upper side of the PCB board 1 and cooperating with the base 111, sliding openings 114 on the front and rear sides of the base 111, movable blocks 115 slidably engaged with the inner walls of the two sliding openings 114, a sealing plate 116 fixedly connected to the adjacent side of the two movable blocks 115, a sealing strip 117 fixedly connected to one side of the sealing plate 116 and abutting against the sliding openings 114, and a sealing strip 117 disposed on the front and rear sides of the base 111. The ventilation openings 118 on both sides are initially positioned by the limiting rod 112 on the upper side of the inner wall of the base 111 and the limiting hole 15 on the PCB board 1. The connecting cover 113 is threadedly connected to the PCB board 1 by the tightening bolt 16 to fix the overall structure. The sealing plate 116 slides in the sliding port 114 of the base 111 with the help of the movable block 115. The sliding port 114 is sealed by the sealing strip 117 and can be fitted with the ventilation opening 118 to control its opening and closing. The dustproof mesh 12 on the inner wall of the ventilation opening 118 can prevent dust from entering during ventilation and heat dissipation. The toggle block 13 on the outer side of the movable block 115 facilitates the operation of the sliding of the sealing plate 116, thereby ensuring the stability and protection of the internal components of the expansion dock.

[0030] Please see Figure 1 The upper side of the base 111 has multiple hidden slots 18, which are respectively engaged with the TC male connector 2, the 9pin USB-A female connector 5, the 16pin Type-C female connector 6, and the 24pin Type-C female connector 7. This engagement method ensures that each interface is precisely matched with the base 111, which stabilizes the position of each interface and ensures the overall structural stability.

[0031] Please see Figure 3 and Figure 4 The inner walls of the two vents 118 are fixedly connected with dustproof nets 12. The dustproof nets 12 can be made of soft materials, which can protect against hair and other impurities during daily use, thereby effectively preventing external dust and other impurities from entering while meeting heat dissipation requirements.

[0032] Please see Figure 4 Each of the two movable blocks 115 is fixedly connected to a toggle block 13 on the opposite side. Each of the two toggle blocks 13 is fixedly connected to a soft sleeve 14 on the outer side. By toggling the toggle block 13 with the soft sleeve 14, the movable block 115 can be easily moved, thereby causing the sealing plate 116 connected to it to slide in the corresponding position, so as to realize the control of the opening and closing state of the vent 118 and other operations.

[0033] Please see Figure 1 and Figure 3The upper side of the connecting cover 113 is provided with multiple tightening bolts 16, and the upper side of the multiple limiting holes 15 is provided with threaded holes 17 that are threadedly engaged with the multiple tightening bolts 16. The multiple tightening bolts 16 provided on the upper side of the connecting cover 113 can be threadedly engaged with the threaded holes 17 opened next to the upper limiting holes 15 on the PCB board 1. By tightening the tightening bolts 16, they are gradually pushed into the threaded holes 17, thereby making the connecting cover 113 and the base 111 fit tightly together, realizing the stable fixation of the overall structure of the dock and ensuring that each component is in a stable state.

[0034] The implementation principle of the integrated flash memory storage fast-charging USB-C docking station and its installation structure in this application embodiment is as follows: In use, it first connects to terminal devices such as computers and mobile phones via the TC male connector 2 on the lower side of the PCB board 1, establishing a connection foundation with external devices. The hub chip 3, located at the center of the upper side of the PCB board 1, plays a crucial role in expanding the interface, extending the single upstream interface from the TC male connector 2 into multiple downstream interfaces, facilitating the connection of multiple external devices. The inductor module 4 regulates and stabilizes the current and voltage in the circuit, providing a stable 5V regulated power supply to the hub chip 3 and each downstream port, ensuring the normal operation of all components.

[0035] Each interface has its own function. For example, the downstream interfaces such as the 9-pin USB-A female connector 5, the 16-pin Type-C female connector 6, and the 24-pin Type-C female connector 7 interact with the TC male connector 2 through the hub chip 3 to achieve data transmission. At the same time, some interfaces also have a certain power supply capability. The PD protocol chip 8 on the bottom is responsible for communicating with the external power supply (the PD charger connected through the 16-pin Type-C female connector 6) to obtain power through the fast charging protocol and output power and the corresponding PD fast charging protocol to the terminal device. Under certain circumstances, it can also request 5V power for the downstream ports. The MOSFET 9 controls the power output switch of the TC male connector 2 port to achieve reasonable control of the power output. The flash memory module 10 enables the terminal device to read and write data through the hub chip 3 to achieve storage function. It integrates flash memory storage function, breaking the limitation of most docking stations on the market that do not have storage function. It realizes the multi-functional integration of "fast charging + data + storage", meets the user's needs in terms of device connection, fast charging and data storage, and improves the practicality and use value of the device.

[0036] The limiting rod 112 on the upper side of the inner wall of the base 111 in the protective mechanism 11 cooperates with the limiting hole 15 of the PCB board 1 to achieve the initial positioning of the PCB board 1. The hidden groove 18 on the upper side of the base 111 accurately engages each interface, ensuring precise fit between the interface and the base 111. The connecting cover 113 is threadedly connected to the threaded hole 17 on the PCB board 1 by the tightening bolt 16, ensuring a tight fit with the base 111 and completing the overall structural fixation. The sealing plate 116 slides within the sliding opening 114 of the base 111 using the movable blocks 115 on both sides, sealing the sliding opening 114 through the sealing strip 117. It can also fit against the ventilation opening 118, serving to seal or open the ventilation opening 118. The dustproof mesh 12 on the inner wall of the 18 prevents dust from entering during ventilation and heat dissipation. The toggle block 13 on the outer side of the movable block 115 facilitates the sliding of the sealing plate 116. When not in use, the sealing plate 116 seals the ventilation opening 118, and the sealing strip 17 seals the sliding opening 114. This effectively prevents external factors such as dust and moisture from corroding the internal core components (such as the hub chip 3, PD protocol chip 8, flash memory module 10, etc.), extending the service life of the expansion dock. In addition, the ventilation opening 118 is equipped with a dustproof mesh 12, which prevents dust from entering while ensuring heat dissipation requirements, ensuring that the expansion dock can work stably and reliably in a good environment. The sealing plate 116 and the base 111 can be bonded together with rubber, which has a certain damping effect.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
