Description

Technical Field

[0001] This utility model relates to the field of docking station technology, and in particular to a docking station that prevents data cables from falling off. Background Technology

[0002] Docks are expansion accessories designed to address the lack of interfaces on electronic devices. By integrating ports such as HDMI, USB, and network cards, they enable the connection of multiple devices, meeting the needs of scenarios such as office work, entertainment, and meetings. With the trend towards thinner and lighter devices, docks are evolving towards portability, high-speed transmission (such as Thunderbolt 4 / USB4), and multi-functional integration, becoming a core hub for mobile office and digital life.

[0003] While existing data cable detachment prevention docking stations have the function of preventing data cables from falling off, some use clips for fixing, which is not very effective, while others use bolts, which is cumbersome and affects the insertion and removal of data cables. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing technologies, such as those that use clips for fixing, which have poor fixing effect, and those that use bolts for fixing, which are cumbersome and affect the plugging and unplugging of data cables. Therefore, this utility model proposes an expansion dock that prevents data cables from falling off.

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

[0006] A data cable detachment prevention docking station includes:

[0007] The expansion dock body has multiple USB ports on one side, and each of the multiple USB ports is connected to a data cable body.

[0008] The upper and lower wrapping sleeves are rotatably mounted on the docking station body. The bottom sides of the data cable body are fixedly connected with embedding strips, and the top sides of the lower wrapping sleeve are provided with embedding grooves, with the embedding strips correspondingly embedded in the embedding grooves.

[0009] The device also includes a flip assembly located on both sides of the data cable body, the upper sleeve, and the lower sleeve. The flip assembly includes a square slider slidably disposed within the docking station body, a rotating shaft fixedly connected to both sides of the upper and lower sleeves, a torsion spring sleeved on the rotating shaft, and a tension spring connecting the inner wall of the USB interface and the square slider.

[0010] In one possible design, the square slider is rotatably sleeved on the outer wall of the rotating shaft, and the two ends of the torsion spring are connected to the data cable body and the square slider respectively via hooks.

[0011] In one possible design, the USB interface has four tension springs, the two ends of which are connected to the inner wall of the USB interface and the square slider respectively via hooks.

[0012] In one possible design, both the data cable body and one end of the connecting cable are fixedly connected to an L-shaped pull plate, and the L-shaped pull plate is embedded in the USB interface.

[0013] In one possible design, a connecting cable is electrically connected to one side of the docking station body, and data cable bodies are correspondingly plugged into the plurality of USB ports.

[0014] In one possible design, the bottom of the docking station body is provided with an anti-slip pad, which is used to increase friction with the desktop.

[0015] In this application, the docking station body is placed on a table via an anti-slip pad on its bottom. A connecting cable on one side of the docking station body is used to connect to a computer. When the data cable is connected to the docking station body, pulling on the L-shaped pull plates on the upper and lower covers causes the upper and lower covers to slide outwards from the docking station body. The upper and lower covers slide with the aid of square sliders on both sides. As the square sliders slide, they stretch the tension springs, causing the upper and lower covers to flip upwards and downwards respectively. The upper and lower covers are respectively assisted by two square sliders on their sides. The rotating shaft on the side flips inside the square slider. At the same time, the upper and lower sleeves cooperate with the corresponding square sliders to generate torque on the torsion spring. The data cable body is inserted into the corresponding USB interface, which pulls the two L-shaped pull plates together. The L-shaped pull plates close together, and the insert strip is pressed into the insert groove to wrap the insertion end of the data cable body. At the same time, the tension spring pulls the upper and lower sleeves to slide into the docking station body. One end of the upper and lower sleeves presses against one side of the insertion end of the data cable body, making the insertion end of the data cable body more secure.

[0016] Beneficial Effects: In this utility model, the expansion dock for preventing data cable detachment utilizes a flip-wrapping structure of the upper and lower sleeves, combined with a snap-fit ​​design where the insert strip is embedded in the insert groove. This ensures a tight fit between the upper and lower sleeves. When the data cable is inserted, the upper and lower sleeves automatically slide inward under the elastic force of the tension spring, with one end pressing against the insertion end. Simultaneously, the torque generated by the torsion spring drives the upper and lower sleeves to adhere tightly to the interface surface, effectively solving the problem of easy loosening of traditional snap-fit ​​devices. This mechanical linkage locking method significantly improves the reliability of the fixation, maintaining connection stability even under external pulling forces.

[0017] In this utility model, the expansion dock for preventing data cable detachment features a pull-out L-shaped pull plate trigger structure. Users only need to pull the L-shaped pull plate with one hand to unfold the upper and lower covers. After inserting the data cable, releasing the pull plate will lock it in place through the automatic reset function of the tension spring. The entire process requires no additional tools. Furthermore, the sliding and flipping motion of the upper and lower covers is ensured by the coordinated design of the square slider guide rail and the rotating shaft, ensuring smooth and jam-free operation. This design significantly shortens the insertion and removal time, making it especially suitable for high-frequency data transmission scenarios.

[0018] In this invention, the combined action of tension spring and torsion spring ensures locking force while simplifying the operation process by utilizing the self-resetting characteristics of the mechanical structure. Compared with a single buckle or bolt solution, this design avoids the risk of fixation failure and overcomes the problem of operational complexity. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment: Refer to Figure 1This is a docking station designed to prevent data cables from falling off. It is used in the docking station industry. The docking station body 1 has an anti-slip pad 4 on its bottom, made of silicone material in a rectangular raised structure, which is fixed to the four corners of the bottom surface of the body 1 by adhesive bonding. Three standard USB ports 5 are located on one side of the body 1. Two sets of tension springs 12 are installed on the inner wall of each port 5. Each set of tension springs 12 consists of two 304 stainless steel springs with a diameter of 0.8 mm, a spring constant of 1.2 N / mm, a natural length of 15 mm, and a maximum tensile strength of 12 mm. The two ends are connected to a fixing ring pre-embedded in the inner wall of the port 5 and a connecting ring on the side wall of a square slider 11 via M2.5 metal hooks.

[0025] Reference Figure 3 Each USB port 5 contains a data cable body 3 and a connecting cable 2. The data cable body 3 adopts the USB 3.0 standard specification, and its plug end is fixed with an embedded strip 9 by injection molding. The embedded strip 9 is made of wedge-shaped nylon material with a trapezoidal cross-section. The plug end of the connecting cable 2 has a corresponding embedded groove 10 with a depth of 3 mm, forming an interference fit with the embedded strip 9. Both the upper sleeve 6 and the lower sleeve 7 have an L-shaped pull plate 8 fixed to one end. The pull plate 8 is made of PC engineering plastic, with a horizontal section length of 10 mm and a vertical section height of 5 mm, and is embedded in a guide groove opened in the inner wall of the USB port 5.

[0026] Reference Figure 3 The flip assembly includes a square slider 11 and a rotating shaft 14. The square slider 11 is made of self-lubricating engineering plastic, with a 5 mm diameter shaft hole in the center. Its outer wall slides into a rectangular groove on the inner wall of the USB interface 5. The rotating shaft 14 is fixed to both sides of the upper sleeve 6 and the lower sleeve 7 by a press-fit process. The shaft has a diameter of 4.8 mm and forms a 0.2 mm clearance fit with the shaft hole of the square slider 11. A torsion spring 13 is sleeved on the outer circumference of the rotating shaft 14. It is made of 0.6 mm diameter piano wire with a spring wire diameter of 0.5 mm, 5 effective turns, and a spring constant of 0.8 N·mm / °. The two ends are bent to form hooks, which are respectively hooked into the Φ2 mm positioning hole on the side wall of the data cable body 3 and the M2 threaded fixing post on the surface of the square slider 11.

[0027] Reference Figure 3 When a data cable needs to be connected, the operator simultaneously pulls the L-shaped pull plate 8 of the upper sleeve 6 and the lower sleeve 7 outward with one hand. The pulling force is transmitted to the tension spring 12 through the square slider 11, causing the four sets of tension springs 12 to stretch and deform synchronously, with a maximum stretch of 12 mm. At this time, the square slider 11 slides outward along the groove, continuing to apply force to make the upper sleeve 6 and the lower sleeve 7 rotate outward around the rotating shaft 14, with a rotation angle of up to 90 degrees. At this time, the torsion spring 13 generates a torsional torque of 3 N·mm.

[0028] Reference Figures 1 to 3After inserting the data cable body 3 into the corresponding USB interface 5, the L-shaped pull plate 8 is slowly released. The elastic potential energy of the tension spring 12 is released, generating a pulling force of 8N, which drives the square slider 11 to slide inward, causing the upper wrapping sleeve 6 and the lower wrapping sleeve 7 to form a wrapping around the insertion end of the data cable body 3. At the same time, the torsional force of the torsion spring 13 drives the upper wrapping sleeve 6 and the lower wrapping sleeve 7 to press tightly against the interface surface, with a contact pressure of up to 2.5N. The insert strip 9 and the insert groove 10 form a mechanical interlocking structure. Combined with the combined force of the tension spring 12 and the torsion spring 13, the holding force of the data cable body 3 reaches 15N, effectively resisting accidental pulling.

[0029] In another embodiment: Reference Figures 1 to 3 Based on Embodiment 1, this implementation method improves upon the previous one by employing a mechanical linkage mechanism to achieve triple anti-drop protection: tension spring 12 provides axial tension, torsion spring 13 generates radial compression, and the embedded strip 9 forms a mechanical interlock. Compared to traditional snap-fit ​​solutions, the tensile strength is increased by 200%, and the insertion / removal life exceeds 5000 cycles. No additional tools are required during operation, and the insertion / removal time is reduced to within 3 seconds, making it particularly suitable for mobile office scenarios requiring frequent insertions and removals.

[0030] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
