Description

Technical Field

[0001] This utility model relates to an expansion dock, specifically a multi-interface expansion dock, belonging to the field of computer peripheral device technology. Background Technology

[0002] A docking station is an external device used to expand the interfaces of electronic devices. It works by using integrated circuits and chips to convert the single interface signal of a connected electronic device (such as a laptop) into multiple types of interface signals, thereby enabling connection to multiple external devices (such as monitors, keyboards, mice, USB flash drives, etc.). A data cable is fixedly connected to the docking station, and a connector is fixedly connected to one end of the data cable. When using the docking station, the connector needs to be plugged into the laptop; when the docking station is no longer needed, the connector needs to be unplugged from the laptop.

[0003] However, once the connector is unplugged from the computer, its plug-in part is directly exposed, making it prone to dust and stains. It may even be damaged by collisions or scratches, affecting subsequent normal use. At the same time, existing docking stations do not store data cables, causing them to be scattered when not in use. This not only takes up space but also makes them easy to get tangled with other items, causing wear or breakage. Utility Model Content

[0004] The purpose of this invention is to provide a multi-interface docking station to solve the above problems. It can protect the connectors when they are unplugged from the laptop and also store the data cables.

[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a multi-interface expansion dock, comprising an expansion dock body, a data cable fixedly connected to the expansion dock body, a connector fixedly connected to the end of the data cable, a protective sleeve engaged with the connector, a connecting seat fixedly connected to the expansion dock body, a connecting part integrally formed on the protective sleeve, the connecting part engaging with the connecting seat, a fixing structure provided on the connecting part, an annular groove provided on the connector, a limiting part integrally formed on the connecting seat, the limiting part engaging with the annular groove, and multiple ports provided on the expansion dock body.

[0006] Preferably, the protective sleeve has a receiving groove inside, and one end of the connector is located inside the receiving groove.

[0007] Preferably, the width of one end of the receiving groove is greater than the width of the other end, and the cross-section of the end of the connecting part is trapezoidal.

[0008] Preferably, the fixing structure includes a pressure block and a slider, two sliders are slidably connected to the connecting part, and a locking block is fixedly connected to the slider. The locking block is slidably connected to the connecting part, one end of the locking block is engaged with the connecting seat, and a spring abuts between the two sliders.

[0009] Preferably, a limiting shaft is fixedly connected to the card block, one end of the spring is sleeved outside one of the limiting shafts, and the other end of the spring is sleeved outside the other limiting shaft.

[0010] Preferably, the cross-section of the card block near the connecting seat is trapezoidal, and the cross-section of the slider as a whole is L-shaped.

[0011] Preferably, one end of the slider is fixedly connected to a pressure block, and the two sliders are symmetrically distributed about the middle of the protective sleeve.

[0012] Preferably, a connecting strap is fixedly connected to the protective sleeve, and a movable sleeve is fixedly connected to one end of the connecting strap. The movable sleeve is fitted over the outside of the data cable and is movably connected to the data cable.

[0013] The beneficial effects of this utility model are as follows: When the connector is unplugged from the laptop, a protective sleeve can be placed over its end, thus protecting the plug-in part at the end. This prevents the surface of the plug-in part from getting dirty and avoids damage from impacts and friction. After the protective sleeve is placed over the end of the connector, it can be moved to insert the plug-in part into the connector. Once the plug-in part is inserted into the connector, the fixing structure will fix the plug-in part, preventing it from detaching from the connector. At the same time, the limiting part and the annular groove engage, preventing the connector from falling out of the protective sleeve. This achieves the fixing of the connector. After the connector is fixed, the data cable will be stored on one side of the docking station body, thus achieving the storage of the data cable and preventing the data cable from being scattered and tangled with other items, causing wear or breakage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6 As shown, a multi-interface expansion dock includes an expansion dock body 1, a data cable 2 fixedly connected to the expansion dock body 1, a connector 3 fixedly connected to the end of the data cable 2, a protective sleeve 4 engaged with the connector 3, a connector base 7 fixedly connected to the expansion dock body 1, a connecting part 6 integrally formed on the protective sleeve 4, the connecting part 6 engaging with the connector base 7, a fixing structure 5 provided on the connecting part 6, an annular groove 9 provided on the connector 3, a limiting part 8 integrally formed on the connector base 7, the limiting part 8 engaging with the annular groove 9, and a plurality of ports 13 provided on the expansion dock body 1.

[0023] As a technical optimization of this utility model, the protective sleeve 4 is provided with a receiving groove 12 inside, which can accommodate the plug part at the end of the connector 3. One end of the connector 3 is located inside the receiving groove 12.

[0024] As a technical optimization of this utility model, the width of one end of the receiving groove 12 is greater than the width of the other end. Therefore, when the plug 3 is inserted into the receiving groove 12 at a certain position, it can abut against the protective sleeve 4, thereby achieving the positioning between the plug 3 and the protective sleeve 4. The cross-section of the end of the connecting part 6 is trapezoidal, so it can play a role in motion guidance when the connecting part 6 is inserted into the connecting seat 7.

[0025] As a technical optimization of this utility model, the fixing structure 5 includes a pressure block 501 and a slider 502. Two sliders 502 are slidably connected to the connecting part 6, and a locking block 503 is fixedly connected to the slider 502. The protective sleeve 4 can be fixed by the two locking blocks 503 engaging with the connecting seat 7. The locking block 503 is slidably connected to the connecting part 6, and one end of the locking block 503 engages with the connecting seat 7. A spring 504 abuts between the two sliders 502. Under the action of the spring 504, the locking block 503 can always be engaged with the connecting seat 7.

[0026] As a technical optimization of this utility model, a limiting shaft 505 is fixedly connected to the locking block 503, one end of the spring 504 is sleeved on the outside of one of the limiting shafts 505, and the other end of the spring 504 is sleeved on the outside of the other limiting shaft 505. The limiting shaft 505 can limit the spring 504 and prevent the spring 504 from coming off between the two locking blocks 503.

[0027] As a technical optimization of this utility model, the cross-section of the locking block 503 near the connecting seat 7 is trapezoidal, so it can play a motion guiding role when the locking block 503 and the connecting seat 7 are engaged. The overall cross-section of the slider 502 is L-shaped.

[0028] As a technical optimization of this utility model, one end of the slider 502 is fixedly connected to a pressure block 501. The pressure block 501 can increase the contact area with the finger, thereby making it more comfortable to press. The two sliders 502 are symmetrically distributed about the middle of the protective sleeve 4.

[0029] As a technical optimization of this utility model, a connecting strap 10 is fixedly connected to the protective sleeve 4, and a movable sleeve 11 is fixedly connected to one end of the connecting strap 10. The movable sleeve 11 is fitted outside the data cable 2 and is movably connected to the data cable 2. Therefore, the protective sleeve 4 can be prevented from falling off and being lost after the connector 3 is pulled out from the protective sleeve 4.

[0030] In use, when the connector 3 is unplugged from the laptop, the protective sleeve 4 can be placed over its end. This protective sleeve 4 shields and protects the connector portion, preventing dirt from accumulating on the surface and protecting it from impact and friction damage. Furthermore, once the protective sleeve 4 is on the end of the connector 3, it can be moved to allow the connecting part 6 to insert into the connector 7. When the connecting part 6 is inserted into the connector 7, the two locking blocks 503 engage with the connector 7 under the action of the spring 504, preventing it from detaching from the connector 7. Simultaneously, the limiting part 8 engages with the annular groove 9, preventing the connector 3 from slipping out of the protective sleeve 4. The internal parts detach, thus securing the connector 3. After the connector 3 is secured, the data cable 2 will be stored on one side of the docking station body 1, thereby storing the data cable 2 and preventing it from being scattered and tangled with other items, which could cause wear or breakage. When the docking station body 1 needs to be used again, the two pressure blocks 501 can be pressed simultaneously. The movement of the pressure blocks 501 will cause the slider 502 to move, which in turn will cause the locking block 503 to move away from the connector 7. The spring 504 will retract. When the locking block 503 is no longer engaged with the connector 7, the protective cover 4 can be moved to separate the connecting part 6 from the connector 7. Then the connector 3 can be pulled out from inside the protective cover 4 and inserted into the laptop.
