Description

Technical Field

[0001] This utility model relates to the field of docking station technology, and in particular to a peripheral docking station for distance learning. Background Technology

[0002] As is well known, a docking station for distance learning is a multi-functional device that connects computers or mobile devices to various external devices, expanding their interfaces and functions. Through the docking station, teachers can easily connect projectors, monitors, microphones, speakers, cameras, and other teaching equipment to enhance teaching effectiveness.

[0003] However, traditional docking stations for distance learning are often not convenient for dust protection of their interfaces when not in use. Dust entering the interfaces can easily lead to poor contact, affecting signal transmission between the docking station and external devices. This can result in problems such as sudden disconnection of the device, screen flickering, or sound lag during teaching, interfering with the normal progress of teaching. Therefore, technical improvements are urgently needed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a peripheral expansion dock for distance learning. When in use, the protective plate is pressed and brought closer to the interface. At this time, the arc-shaped push block is compressed by the force that causes its return spring to compress. When the arc-shaped push block is opposite to the mounting groove, the return spring releases its force, causing the arc-shaped push block to engage with the mounting groove. This protects the interface when not in use, thereby ensuring the stability of the interface performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A peripheral expansion dock for distance learning includes an expansion dock. Protective plates are rotatably connected to both sides of the middle portion of the front outer wall of the expansion dock. A storage slot is formed in the middle portion of the front outer wall of each protective plate. An arc-shaped push block is slidably connected to the inner wall of each storage slot. A return spring is fixedly connected to the rear end of each arc-shaped push block. Installation slots are formed on both sides of the front inner wall of the expansion dock. A sliding groove is formed at the rear end of the inner wall of each installation slot. A slider is slidably connected to the inner wall of each sliding groove. An auxiliary wedge is fixedly connected to the front end of each slider. A second sliding groove is formed on the inner wall of the adjacent side of each installation slot. A second slider is slidably connected to the inner wall of the second sliding groove. An active wedge is fixedly connected to the outer wall of the adjacent side of each slider.

[0007] A mounting box is fixedly connected to the center of the upper surface of the expansion dock. Placement slots are provided on both sides of the lower surface of the mounting box. The inner walls of adjacent placement slots are connected through each other. A servo motor is fixedly connected to one side of the top surface of the placement slot. Mounting brackets are fixedly connected to the lower ends of the inner walls on both sides of the placement slot. A drive rod is fixedly connected to the output end of the servo motor. A driven rod is rotatably connected to the top surface on the other side of the placement slot. Multiple cooling fans are fixedly connected to the lower ends of the drive rod and the driven rod.

[0008] Compared with existing peripheral expansion docks for distance learning, this peripheral expansion dock for distance learning, when used, drives the auxiliary wedge to move and push out the active wedge when the arc-shaped push block engages with the mounting slot. When needed, the active wedge can be installed to drive the auxiliary wedge to disengage the arc-shaped push block from the mounting slot, resulting in higher practical performance.

[0009] Furthermore, the front outer wall of the expansion dock is provided with multiple interfaces;

[0010] The above technical solution facilitates data transmission through the interface.

[0011] Furthermore, ventilation slots are provided on both sides of the outer wall at the rear end of the expansion dock, and dust filters are provided on the inner walls of the ventilation slots.

[0012] The above technical solution uses a dust filter to prevent dust from entering.

[0013] Furthermore, limit grooves are provided on both sides of the inner wall of the storage slot, and limit blocks are fixedly connected to both sides of the outer wall of the arc-shaped push block. The limit blocks are slidably connected to the inner wall of the limit groove respectively.

[0014] With the above technical solution, the limiting blocks are slidably connected to the inner wall of the limiting groove, which facilitates the limiting of the arc-shaped push block.

[0015] Furthermore, the arc-shaped push block abuts against the auxiliary wedge block, and the auxiliary wedge block abuts against the active wedge block;

[0016] The above technical solution allows the arc-shaped pusher to facilitate the movement of the auxiliary wedge, thereby indirectly driving the active wedge to move.

[0017] Furthermore, multiple air inlet slots are provided on both sides of the upper surface of the mounting box, and a dust filter screen is provided on the inner wall of each air inlet slot;

[0018] The above technical solution effectively prevents dust from entering through the dust filter.

[0019] Furthermore, both the driving rod and the driven rod are fitted with transmission wheels on their outer walls, and the outer walls of the transmission wheels are fitted with synchronous belts.

[0020] The above technical solution uses a synchronous belt fitted on the outer wall of the transmission wheel to facilitate the rotation of the driving rod and the driven rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a peripheral expansion dock for distance learning. Compared with existing peripheral expansion docks for distance learning, when this peripheral expansion dock for distance learning is in use, by pressing the protective plate and continuously bringing it closer to the interface, the arc-shaped push block is compressed by the force that drives its return spring. When the arc-shaped push block is opposite to the mounting groove, the return spring releases its force and causes the arc-shaped push block to engage with the mounting groove, thereby protecting the interface when not in use and ensuring the stability of the interface performance.

[0023] 2. The present invention proposes a peripheral expansion dock for distance learning. Compared with existing peripheral expansion docks for distance learning, when the arc-shaped push block engages with the mounting slot, it drives the auxiliary wedge block to move and simultaneously drives the active wedge block to push out. When needed, the active wedge block can be installed to drive the auxiliary wedge block to disengage the arc-shaped push block from the mounting slot, resulting in higher practical performance.

[0037] Compared with existing peripheral expansion docks for distance learning, this peripheral expansion dock for distance learning, when used, drives the auxiliary wedge 26 to move and simultaneously drives the active wedge 29 to push out when the arc-shaped push block 21 engages with the mounting slot 25. When needed, the active wedge 29 can be installed to drive the auxiliary wedge 26 to disengage the arc-shaped push block 21 from the mounting slot 25, which has higher practical performance.

[0038] The front outer wall of the expansion dock 1 is equipped with multiple interfaces 11;

[0039] Interface 11 facilitates data transmission.

[0040] Ventilation slots 13 are provided on both sides of the outer wall at the rear end of the expansion dock 1, and dust filters 14 are provided on the inner wall of each ventilation slot 13.
