Description

Technical Field

[0001] This utility model relates to the field of docking stations, and in particular to a modular HUB. Background Technology

[0002] Currently, most HUBs on the market have fixed and single interface combinations. A multi-functional HUB can only use a single, fixed adapter function. For consumers, some users cannot fully utilize the functions of the interfaces, thus paying for additional functions.

Existing HUB designs cannot fully meet the needs of all market users and cannot adapt to different usage scenarios. Therefore, there is a need for multi-functional HUBs that allow users to purchase one or more interfaces as needed, which can be combined with existing products to meet the interface requirements of different users.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 4 As shown, a modular HUB is characterized by comprising a mother HUB1 and a daughter HUB2, which are detachably connected by a connecting structure. The mother HUB1 and the daughter HUB2 are respectively provided with a first connecting terminal 11 and a second connecting terminal 21 for external communication. A connecting terminal for electrical communication and signal transmission is provided between the mother HUB1 and the daughter HUB2. When the mother HUB1 and the daughter HUB2 are fixed together by the connecting structure, the mother HUB1 and the daughter HUB2 achieve electrical communication and signal transmission through the connecting terminal.

[0035] By connecting the mother HUB1 and daughter HUB2 together using a connection structure, electrical connection and signal transmission are achieved through the connecting terminals. This allows for the addition of a single interface to the existing multi-functional HUB interface, or the addition of a multi-interface HUB as needed, maximizing the utilization of the multi-functional HUB. At the same time, the daughter HUB2 has fewer functions, is small in size and easy to carry, and its modular design provides an excellent user experience.

[0036] Since the mother HUB1 and daughter HUB2 are fixed together by a connecting structure, and it is necessary to quickly fix or disassemble them during use, in this embodiment, the connecting structure includes a first magnetic suction member 31 inside the mother HUB1 and a corresponding second magnetic suction member 32 inside the daughter HUB2. A groove inside the housing is provided for positioning the first magnetic suction member 31 and the second magnetic suction member 32. The first magnetic suction member 31 and the second magnetic suction member 32 are fixed in the groove with glue. Thus, no connecting parts are visible from the outside of the housing, maintaining the overall aesthetics of the product. Furthermore, when the two are attracted and fixed together, the mother HUB1 and daughter HUB2 have a certain attractive force as they approach each other, guiding them to be fixed together, making the use process more convenient.

[0037] Of course, other structures can also be used to fix the mother HUB1 and the daughter HUB2 together. For example, the mother HUB1 is provided with a first snap-fit ​​component, and the daughter HUB2 is provided with a corresponding first snap-fit ​​component. The first snap-fit ​​component and the second snap-fit ​​component are snapped together. The first snap-fit ​​component and the second snap-fit ​​component use a snap-on method to fix the mother HUB1 and the daughter HUB2 together.

[0038] During the process of fixing the sub-type HUB2 and the mother type HUB1, it is not only necessary to bring the two closer together, but also to establish electrical connection and signal transmission between them. The mother type HUB1 is provided with a positioning groove 12. When the sub-type HUB2 is in the positioning groove 12, it is fixed to the mother type HUB1 through a connecting structure. At this time, the sub-type HUB2 is just stuck in the positioning groove 12. In this way, during the connection process between the sub-type HUB2 and the mother type HUB1, the positioning groove 12 can be used for positioning, and then the two can be connected and fixed together through the connecting structure, thereby realizing electrical connection and signal transmission between the sub-type HUB2 and the mother type HUB1.

[0039] At this time, the connecting terminal is divided into two parts. Specifically, the connecting terminal includes an electrical terminal 41 for electrical connection and a signal terminal 42 for signal transmission.

[0040] Specifically, the electrical terminal 41 includes a screw fixing bracket 411 disposed inside the housing of the female HUB1 or the female HUB2, and the screw fixing bracket 411 is fixed to the position inside the housing by screws 417.

[0041] The magnet holder 412 is positioned between the housing and the screw 417 fixing clip, and has a vertical hole. The magnet holder 412 is sleeved on the outside of the screw 417 at the position of the vertical hole.

[0042] Spring 413 is sleeved on the outside of screw 417 and is located between the magnet retaining clip and the screw 417 retaining clip;

[0043] The conductive magnet 414 is fixed to the side of the magnet holder 412;

[0044] A through hole 415 is provided at the corresponding position of the mother HUB1 or daughter HUB2 housing, and the through magnet 414 extends to the outside of the mother HUB1 or daughter HUB2 housing at the position of the through hole 415.

[0045] The conductive piece 416 has one end connected to the PCB board inside the mother HUB1 or daughter HUB2, and the other end is provided with a contact 4161. The contact 4161 is located on the side of the conductive magnet 414. When the conductive magnets 414 of the mother HUB1 and daughter HUB2 are aligned and fixed together, the conductive piece 416 of the mother HUB1 and daughter HUB2 contacts the contact 4161 of the conductive magnet 414 to electrically connect the mother HUB1 and daughter HUB2.

[0046] First, the conductive magnet 414 is glued to the side of the magnet holder 412. Then, the magnetic clamp is placed inside the housing, so that the conductive magnet 414 protrudes from the through hole 415. Next, the screw 417 is passed through the screw holder 411, and the spring 413 is sleeved on the outside of the screw 417. Finally, the screw 417 is passed through the clearance hole of the magnet holder 412 and fixed to the housing. At this time, the two ends of the spring 413 abut against the magnet holder 412 and the screw holder 411 respectively. Under the action of the spring 413, The conducting magnet 414 moves outward and is higher than the outer side of the housing, thus completing the assembly of the electrical terminal 41. At this time, the conducting magnets 414 of both the female HUB1 and the female HUB2 are higher than the outer side of the housing. When the two housings are pressed together and the conducting magnets 414 are aligned, the two conducting magnets 414 come into contact and move inward at the same time, so that the magnet fixing bracket 412 moves inward synchronously. During the movement, the conducting magnet 414 comes into contact with the conducting piece 416, thus realizing the electrical connection between the female HUB1 and the female HUB2.

[0047] At this time, in order to ensure that the conducting magnet 414 can achieve electrical connection, a conductive material, such as nickel or copper, is electroplated on the surface of the conducting magnet 414, so that electrical connection is achieved under the effect of magnetic connection. The number of conducting magnets 414 can be set according to actual needs, mainly to achieve electrical connection between the female HUB1 and the female HUB2.

[0048] When fixing the mother HUB1 and daughter HUB2, the conducting magnet 414 will move. Therefore, it is necessary to ensure that the conducting magnet 414 remains in a straight line during the movement. In this embodiment, the housing is provided with a positioning post 410, and the magnet fixing bracket 412 is provided with a positioning hole 4121 corresponding to the positioning post 410. The magnet fixing bracket 412 moves along the direction of the positioning post 410. At this time, the magnet fixing bracket 412 is sleeved on the positioning post 410 of the housing at the positioning hole 4121. In this way, the magnet fixing bracket 412 can maintain a straight line movement during the movement, thereby ensuring that the conducting magnet 414 maintains a straight line movement during the movement, thus ensuring the stability of the electrical connection between the mother HUB1 and daughter HUB2.

[0049] Meanwhile, to further improve the stability of the magnet holder 412 during movement, in this embodiment, the magnet holder 412 is provided with a positioning post 410, and the screw holder 411 is provided with a positioning hole 4121 corresponding to the positioning post 410. The magnet holder 412 moves along the direction of the positioning post 410. Thus, the magnet holder 412 has guide structures in both directions, which further improves the stability of the linear movement of the magnet holder 412 during its movement.

[0050] The conduction piece 416 is used to connect the conduction magnet 414 to the PCB board, so as to achieve the electrical connection between the female HUB1 and the male HUB2. In this embodiment, the conduction piece 416 is in a "C" shape, including an upper horizontal part and a lower horizontal part, which are connected by a vertical part in the middle. The conduction piece 416 is fixed and conducts electricity with the PCB board at the position of the lower horizontal part. The contact point 4161 is arranged at the outer position of the upper horizontal part. The conduction piece 416 is provided with a reinforcing rib 4162 that extends from the upper horizontal part through the vertical part to the lower horizontal part. Since the conduction piece 416 is in a "C" shape and made of a metal material, it has a certain elasticity. Therefore, when contacting the conduction magnet 414, it can ensure a good conduction effect. At the same time, the contact point 4161 where the conduction piece 416 contacts and conducts electricity with the conduction magnet 414 is arranged at the outer position of the upper horizontal part. At this time, the contact point 4161 is a convex design. In this way, during the contact process with the conduction magnet 414, the contact and conduction effect between the conduction piece 416 and the conduction magnet 414 can be ensured. At the same time, since the conduction piece 416 may undergo slight deformation during use, in order not to affect its service life, the conduction piece 416 is provided with a reinforcing rib 4162 that extends from the upper horizontal part through the vertical part to the lower horizontal part. This can improve the overall strength of the conduction piece 416. Of course, at this time, the contact point 4161 is arranged at the outer position of the reinforcing rib 4162. In this way, while improving the strength of the conduction piece 416, it will not affect the deformation of the conduction piece 416 at the position of the contact point 4161, thus ensuring the electrical connection effect between the conduction piece 416 and the conduction magnet 414 at the position of the contact point 4161.

[0051] After the contact point 4161 is arranged on the conduction piece 416, in order to form disconnection and connection with the conduction tooth iron in different states, in this embodiment, the magnet fixing frame 412 is provided with a fixing step for fixing the conduction magnet 414. A through hole 4122 is provided at the bottom of the fixing step. The contact point 4161 of the conduction piece 416 is located on the other side of the magnet fixing frame 412. The contact point 4161 of the conduction piece 416 contacts and conducts electricity with the conduction magnet 414 through the position of the through hole 4122. In this way, the contact point 4161 of the conduction piece 416 and the conduction magnet 414 are respectively arranged on both sides of the magnet fixing frame 412. This can avoid accidental contact between the two. When the conduction magnet 414 moves in the magnet fixing frame 412, it moves synchronously. Then, the moving conduction magnet 414 contacts the contact point 4161 of the conduction piece 416 at the position of the through hole 4122 of the fixing step of the magnet fixing frame 412, thereby achieving the electrical connection between the female HUB1 and the male HUB2.

[0052] In order to ensure signal transmission between the mother HUB1 and the daughter HUB2, in this embodiment, the signal terminal 42 includes pin headers 421 and corresponding female headers 422 respectively disposed on the mother HUB1 and the daughter HUB2. The female headers 422 protrude and are disposed near the side of the daughter HUB2. After setting up the pin header 421 and the corresponding female header 422, when fixing the female HUB1 and the female HUB2 together through the connection structure, the pin header 421 can be inserted into the female header 422, thereby realizing the signal transmission of the female HUB1 and the female HUB2. Of course, at this time, the pin header 421 and the female header 422 are connected to the corresponding PCB board. At the same time, in order to prevent errors during the connection of the female HUB1 and the female HUB2, the female header 422 is protruded and set near the side of the female HUB2. The first magnetic suction member 31 and the second magnetic suction member 32 used to fix the female HUB1 and the female HUB2 are located in the middle of the female HUB2. In this way, when fixing the female HUB1 and the female HUB2 and aligning the pin header 421 and the female header 422, the position is unique, which can avoid the problem of connection errors caused by incorrect position of the female HUB1 and the female HUB2 during the fixing process.

[0053] Finally, to enhance user convenience, the mother HUB1 has multiple connection structures and terminals on its side, with corresponding daughter HUB2s positioned on the side of the mother HUB1. The mother HUB1 has a certain length, while the daughter HUB2s are smaller, allowing multiple daughter HUB2s to be fixed to the side of the mother HUB1, creating a stacked effect similar to building blocks and improving aesthetics during use.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
