DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] See also Figures 1 to 8The present invention provides a docking station structure, comprising a circuit board 1, an upper cover 2 and a lower cover 3. The circuit board 1 is provided with a USB interface 4, a PD chip, a POE switch, an electronic switch, a MOS tube, a network transformer and a step-down chip. The lower cover 3 is provided with a network port holder 5, and the network port holder 5 is integrated with the circuit board 1. The inner top of the upper cover 2 is provided with a plurality of positioning posts 6. The circuit board 1 is arranged between the plurality of positioning posts 6. The upper cover 2 is fixedly connected to the lower cover 3 by bolts and covers the upper part of the lower cover 3. The USB interface 4, the electronic switch and the network port holder 5 all extend out of the outer side of the upper cover 2. The POE switch provides power to energize the circuit board 1, and the PD chip converts the power into PD output to supply power and data connection to the load tablet or mobile phone. An external power adapter can also be connected. The system is compatible with two power supply modes and can operate normally without an external power supply. In this way, the technical problem that the existing docking stations on the market cannot meet the network port power supply requirements and cannot be used if an external power supply cannot be used in special scenarios is solved.

[0023] Among them, the USB interface 4, the PD chip, the POE switch, the electronic switch, the MOS tube, the network transformer, the step-down chip and the network port socket 5 are all electrically connected to the circuit board 1; the USB interface 4 is used to connect external devices that require power; the PD chip is responsible for managing and regulating the power received from the PSE to ensure that the device can use power safely and effectively; the POE switch powers the device through the network cable, avoiding the trouble of requiring an additional power supply, making the deployment of network equipment more flexible and convenient; the electronic switch is used to control the on and off of the circuit, and it can achieve rapid switching of the circuit without mechanical operation; in the POE system, the electronic switch may be used to control the direction of current to protect sensitive components from overcurrent damage; the MOS tube is used to amplify signals or drive other devices; the network transformer is used to isolate the electrical connections between different networks to prevent electrical noise from interfering with signal transmission; the step-down chip is used to reduce the voltage and convert high voltage into low voltage to meet the power requirements of different devices; the network port socket 5 is the physical connection point for the device to communicate with other network devices.

[0024] Secondly, two protective covers 7 are provided at both ends of the upper cover 2. Both ends of the upper cover 2 also have multiple first heat dissipation holes 8, and the protective covers 7 cover the multiple first heat dissipation holes 8. The setting of the first heat dissipation holes 8 can facilitate the discharge of heat generated by the circuit board 1 during operation, thereby playing a role in heat dissipation. The protective cover 7 can prevent a large amount of dust from entering the upper cover 2.

[0025] Again, the expansion dock structure also includes two supporting mechanisms, which include a supporting block 9 and a supporting seat 10. The lower end surface of the lower cover 3 has a plurality of second heat dissipation holes 11, and a plurality of buffer springs 12 are welded on the inner top of the support seat 10. The support block 9 is welded to the corresponding buffer springs 12 and is located below the plurality of buffer springs 12.

The support seat 10 is fixedly connected to the lower cover 3 and is located on one side of the lower cover 3, and is also located on one side of the plurality of second heat dissipation holes 11. The setting of the second heat dissipation holes 11 can facilitate the improvement of the heat dissipation effect. The support block 9 and the support seat 10 can facilitate the support of the lower cover 3 under the action of the buffer springs 12, so that there is sufficient heat dissipation space under the lower cover 3, and at the same time, under the action of the buffer springs 12, it can facilitate the buffering of the lower cover 3.

[0026] In addition, the support mechanism also includes a plurality of positioning rods 13 and anti-slip pads 14. The plurality of positioning rods 13 are respectively fixedly connected to the support seat 10 and are located at the inner top of the support seat 10, and the buffer spring 12 is also sleeved on the corresponding positioning rods 13. The positioning rods 13 are also slidably connected to the support block 9 and are located inside the support block 9. The anti-slip pads 14 are bonded to the support block 9 and are located below the support block 9. The positioning rods 13 can be used to prevent the positioning piece from deviating, and the anti-slip pads 14 can be used to improve the grip, thereby preventing the positioning piece from slipping.

[0027] In the present invention, POE technology is used to utilize the existing Ethernet Cat.5 cabling infrastructure to provide DC power to devices while transmitting data. This technology allows network devices to receive data and power simultaneously through Ethernet cables, thereby simplifying the installation and deployment of equipment, saving costs and improving safety. In this way, it solves the technical problem that existing expansion docks on the market cannot meet the power supply requirements of network ports. For example, in special scenarios where an external power supply cannot be used, the expansion dock cannot be used.

[0028] In the present invention, the 44-57V voltage output by the POE switch is integrated through the network port 5 to form a PD power supply for the tablet or mobile phone.
