Description

Technical Field

[0001] This invention relates to the field of docking station technology, and more particularly to an interchangeable multi-interface docking station. Background Technology

[0002] A docking station, also known as a port replicator, is an external device designed specifically for laptops. By replicating or even expanding the ports of a laptop, it allows for convenient one-stop connection between the laptop and multiple accessories or external devices.

[0003] Currently, docking stations on the market offer interfaces including USB, PCMCIA, Type-C slots, and serial ports. During use, all interfaces are integrated into a single unit within the docking station, and the exposed interfaces facilitate connection to external devices. However, such docking stations may experience issues during use, such as a port becoming worn and unresponsive over time, requiring the entire docking station to be replaced, resulting in wasted resources. Additionally, some interfaces may remain idle during connection, allowing dust to accumulate and potentially causing poor contact when reconnecting to external devices.

[0004] Therefore, we propose an interchangeable multi-interface expansion dock. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art where the docking station interface and the docking station are a whole, and when a certain interface is damaged, the entire docking station needs to be replaced, resulting in resource waste, and when external devices are connected to the computer through the docking station, some interfaces are idle. Therefore, this invention proposes an interchangeable multi-interface docking station.

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

[0007] An interchangeable multi-interface expansion dock includes an expansion dock connection cable. An interchangeable expansion dock is connected to the bottom of the expansion dock connection cable. A circular expansion plug-in base is fixedly connected to the bottom of the interchangeable expansion dock, and an interchangeable plug-in interface is provided at the bottom of the circular expansion plug-in base. A single-type expansion dock is inserted into the inner wall of the interchangeable plug-in interface. An external expansion interface is provided on the inner wall of the single-type expansion dock. A protective shell is movably connected to the outer surface of the interchangeable expansion dock. A protective plate is fixedly connected to the inner wall of the protective shell. An isolation pad is fixedly connected to the inner side of the protective plate. A communicating insertion hole is provided on the inner wall of the protective shell. A sealing slider is rotatably connected to the inner wall of the protective shell. A sealing spring is fixedly connected to the outer surface of the sealing slider. A snap-fit ​​post is fixedly connected to the outer surface of the sealing slider.

[0008] Preferably, the outer surface of the interchangeable expansion dock is provided with an interchangeable rotating groove and a fixed plug-in groove, and the outer surface of the interchangeable expansion dock is fixedly connected with a rotating holding groove.

[0009] Preferably, a stabilizing bracket is fixedly connected to the bottom of the circular expansion plug base, and an anti-slip pad is fixedly connected to the outer surface of the stabilizing bracket. The interchangeable plug interface includes a USB interface, a PCMCIA interface, a Type-C port, and a serial port.

[0010] Preferably, the top of the single-type expansion dock is fixedly connected with an expansion corresponding plug, which is plugged into the interchangeable interface. The external expansion interface includes a USB expansion interface, a PCMCIA expansion interface, a Type-C expansion port, and a serial expansion port.

[0011] Preferably, the bottom of the protective housing is rotatably connected to a stable base, and the top of the stable base is inserted into the bottom of the single-unit expansion dock.

[0012] Preferably, the inner wall of the protective shell is fixedly connected to a rotating ball that is rotatably connected to the inner wall of the interchangeable rotating groove, and the inner wall of the protective shell is threadedly connected to a stabilizing bolt, with an arc-shaped stabilizing block fixedly connected to the inner side of the stabilizing bolt.

[0013] Preferably, a cleaning pad is snapped onto the inner side of the insulating pad, and the inner side of the cleaning pad is rotatably connected to the outer surface of the single-unit expansion dock, with the inner side of the insulating pad fitting against the outer surface of the single-unit expansion dock.

[0014] Preferably, the inner wall of the protective shell is provided with an interchangeable socket, the outer surface of the closed slider is fixedly connected with a buffer pad, and the outer surface of the buffer pad is engaged with the inner wall of the interchangeable socket. The cross-section of the closed slider is set to be arc-shaped, and the inner side of the closed slider is in contact with the outer surface of the single-type expansion dock.

[0015] Preferably, the inner side of the snap-fit ​​post is fixedly connected to a telescopic spring, and the outer side of the snap-fit ​​post is rotatably connected to the inner wall of the protective shell.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By employing a combination of interchangeable docking stations, circular expansion connector bases, and single-port docking stations, when a port on a single-port docking station is damaged, the protective shell can be rotated off the interchangeable docking station for replacement. This achieves the effect of replacing a single port, solving the problem mentioned in the background art where the docking station interface and the docking station are a single unit, requiring the replacement of the entire docking station when a port is damaged, resulting in resource waste. Furthermore, by using a combination of protective shells, protective plates, and insulating pads, after the single-port docking station with the required expansion interface is plugged into the bottom of the circular expansion connector base, the protective shell is installed on the outer surface of the interchangeable docking station to protect it. Simultaneously, when a particular type of port is not in use, the protective shell can be rotated to enclose it, preventing dust from entering the unused port and affecting it. This solves the problem mentioned in the background art where some ports are idle when external devices are connected to a computer via a docking station. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment is an example of an adjustable mechanism for an adjustable multi-interface expansion dock;

[0029] like Figure 1-3 As shown, an interchangeable multi-interface expansion dock includes an expansion dock connection cable 1. An interchangeable mechanism is provided at the bottom of the expansion dock connection cable 1. The interchangeable mechanism includes: an interchangeable expansion dock 2, a circular expansion plug-in base 3, and a single expansion dock 4. The bottom of the expansion dock connection cable 1 is connected to the interchangeable expansion dock 2. The bottom of the interchangeable expansion dock 2 is fixedly connected to the circular expansion plug-in base 3. An interchangeable plug-in interface is provided at the bottom of the circular expansion plug-in base 3. The single expansion dock 4 is inserted into the inner wall of the interchangeable plug-in interface. The inner wall of the single expansion dock 4 is provided with an external expansion interface.

[0030] Through the above technical solution, the expansion dock connection cable 1 and the interchangeable expansion dock 2 adopt the existing expansion dock connection circuit, and the top of the expansion dock connection cable 1 and the interchangeable expansion dock 2 are plugged in. The improvement made by this application to the existing plug-in expansion dock in terms of circuit components is that the expansion interface is oriented downward through the circular expansion plug-in base 3 at the bottom of the interchangeable expansion dock 2, which facilitates plugging and use with the single expansion dock 4. The connection port between the expansion dock connection cable 1 and the computer can be selected according to the actual situation.

[0031] Based on the above, when a single-type docking station 4 is damaged, the protective shell 5 is removed from the interchangeable docking station 2 by rotation, and the damaged single-type docking station 4 is replaced, so as to achieve the effect of a single interface being replaceable.

[0032] Specifically, a stabilizing bracket 301 is fixedly connected to the bottom of the circular expansion dock 3, and an anti-slip pad 302 is fixedly connected to the outer surface of the stabilizing bracket 301. The interchangeable interfaces include a USB interface, a PCMCIA interface, a Type-C port, and a serial port. An expansion corresponding plug 401 is fixedly connected to the top of the single expansion dock 4. The expansion corresponding plug 401 is plugged into the interchangeable interfaces. The external expansion interfaces include a USB expansion interface, a PCMCIA expansion interface, a Type-C expansion port, and a serial expansion port.

[0033] Through the above technical solution, the stabilizing bracket 301 can stabilize the upper end of each single-type expansion dock 4 after it is plugged in. At the same time, the expansion corresponding plug 401 opened inside the single-type expansion dock 4 can be plugged in to the interchangeable plug interface. Meanwhile, the external expansion plug interface opened on the inner wall of the single-type expansion dock 4 can expand the interchangeable plug interface. In addition, if a single plug is damaged, the expansion plug of the interchangeable expansion dock 2 can be quickly replaced by replacing the single-type expansion dock 4.

[0034] Furthermore, when carrying the interchangeable docking station 2, the required single docking station 4 can be assembled onto the bottom of the interchangeable docking station 2 according to one's own needs, reducing the carrying weight. At the same time, the single docking station 4 and the protective shell 5 can be removed from the interchangeable docking station 2 during the carrying process, reducing the carrying volume and achieving the effect of easy carrying.

[0035] Based on the above, the interchangeable interfaces can be designed as multiple interfaces corresponding to the actual situation, and are not limited to the four types of interfaces mentioned above.

[0036] Example 2

[0037] This embodiment is an example of an adjustable multi-interface expansion dock protection mechanism;

[0038] like Figures 4-7 As shown, the protective mechanism is located on the outer surface of the interchangeable expansion dock 2. The protective mechanism includes: a protective shell 5, a protective plate 6, an isolation pad 7, and a sealing slider 8. The sealing slider 8 has a fixing component inside, which consists of a sealing spring 9 and a snap-fit ​​post 10. The protective shell 5 is movably connected to the outer surface of the interchangeable expansion dock 2, and the protective plate 6 is fixedly connected to the inner wall of the protective shell 5. The isolation pad 7 is fixedly connected to the inner side of the protective plate 6, and a connecting hole is opened on the inner wall of the protective shell 5. The sealing slider 8 is rotatably connected to the inner wall of the protective shell 5, and the sealing spring 9 is fixedly connected to the outer surface of the sealing slider 8. The snap-fit ​​post 10 is fixedly connected to the outer surface of the sealing slider 8.

[0039] Through the above technical solution, after the single-type expansion dock 4 with the required expansion interface is plugged into the bottom of the circular expansion plug base 3, the single-type expansion dock 4 is protected by installing the protective shell 5 on the outer surface of the interchangeable expansion dock 2. At the same time, when the expansion dock with a certain type of interface is not used, it can be sealed inside the protective shell 5 by rotating it to prevent dust from entering the unused interface and affecting it.

[0040] Specifically, the outer surface of the interchangeable expansion dock 2 is provided with an interchangeable rotating groove 201 and a fixed plug-in groove 202, and the outer surface of the interchangeable expansion dock 2 is fixedly connected with a rotating holding groove 203. The bottom of the protective shell 5 is rotatably connected with a stable base 501, and the top of the stable base 501 is plugged into the bottom of the single expansion dock 4. The inner wall of the protective shell 5 is fixedly connected with a rotating ball 502 that is rotatably connected to the inner wall of the interchangeable rotating groove 201, and the inner wall of the protective shell 5 is threadedly connected with a stabilizing bolt 503. An arc-shaped stabilizing block is fixedly connected to the inner side of the stabilizing bolt 503.

[0041] Through the above technical solution, the bottom of the interchangeable rotating slot 201 is provided with an installation groove for the installation of the protective shell 5. The rotating ball 502 can be moved along the installation groove into the interchangeable rotating slot 201. At the same time, the bottom of the single-type expansion dock 4 is stabilized and protected by the stabilizing base 501. When using the interchangeable expansion dock 2, the protective shell 5 can be rotated by hand by rotating the handle 203 to close and protect the idle expansion dock port. Then, the arc-shaped stabilizing block is brought close to the fixed plug slot 202 by rotating the stabilizing bolt 503 to fix the rotation angle of the protective shell 5.

[0042] Specifically, the inner side of the isolation pad 7 is snapped with the cleaning pad 701, and the inner side of the cleaning pad 701 is rotatably connected to the outer surface of the single-unit expansion dock 4, and the inner side of the isolation pad 7 is in contact with the outer surface of the single-unit expansion dock 4.

[0043] Through the above technical solution, when the isolation pad 7 rotates with the protective plate 6, it will clean the outer surface of the single-unit expansion dock 4 on its inner side. At the same time, by regularly replacing the cleaning pad 701, the cleaning efficiency of the isolation pad 7 on the single-unit expansion dock 4 can be ensured. Meanwhile, the isolation pad 7, which is attached to the outer surface of the single-unit expansion dock 4, can seal and protect the interface when it is not in use.

[0044] Specifically, the inner wall of the protective shell 5 is provided with an interchangeable socket, the outer surface of the closed slider 8 is fixedly connected with a buffer pad 801, and the outer surface of the buffer pad 801 is engaged with the inner wall of the interchangeable socket. The cross-section of the closed slider 8 is set to be arc-shaped, and the inner side of the closed slider 8 is in contact with the outer surface of the single-type expansion dock 4. The inner side of the locking post 10 is fixedly connected with a telescopic spring 1001, and the outer side of the locking post 10 is rotatably connected to the inner wall of the protective shell 5.

[0045] With the above technical solution, before rotating the protective shell 5, the corresponding replacement socket can be opened by pre-rotating the closed slider 8. The number and position of the replacement socket can be changed according to the user's needs. When the closed slider 8 is away from the part that is engaged with the replacement socket, the snap-fit ​​post 10 can be fixed into the closed fixing hole opened on the inner wall of the protective shell 5 by pressing the telescopic spring 1001.

[0046] This invention connects a single-type expansion dock 4 to the bottom of a circular expansion base 3 and an interchangeable expansion dock 2. The interface of the interchangeable expansion dock 2 is expanded in a single manner through the external expansion interface. Then, the single-type expansion dock 4 is stabilized by the stabilizing bracket 301 and the stabilizing base 501. At the same time, the outer surface of the single-type expansion dock 4 is protected by the installed protective shell 5. This completes the operation of expanding the interface of the interchangeable expansion dock 2 and protecting the single-type expansion dock 4.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
