[0039] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0040] Reference will be made below to Figures 1 - 16 describe the hub assembly 100 according to an embodiment of the present invention.

[0041] Referring to Figure 2 、 Figure 3 and Figure 15 According to an embodiment of the present invention, the hub assembly 100 includes a base 1 and a hub 2. The base 1 includes a base body 11 and a first magnetic part 12. The first magnetic part 12 is provided on the base body 11. The hub 2 is detachably fixed to the base 1. The hub 2 includes a hub body 21 and a second magnetic part 22. The hub body 21 includes a housing 211 and a circuit board assembly 212. The circuit board assembly 212 is provided in the housing 211. The second magnetic part 22 is provided on the housing 211 and the second magnetic part 22 is adapted to attract the first magnetic part 12.

[0042] The base 1 can support and fix the hub 2. The hub 2 can be connected to multiple external devices at the same time and can provide a function of transferring for multiple external devices so that multiple external devices are electrically connected at the same time. The circuit board assembly 212 is provided in the housing 211. The housing 211 can support and protect the circuit board assembly 212, can avoid damage to the circuit board assembly 212 caused by external impurities (such as dust and moisture), and can also resist a certain amount of external impact to avoid damage to the circuit board assembly 212 due to external impact, ensuring that the circuit board assembly 212 works in a safe and stable environment.

[0043] For example, the hub 2 can connect a first external device (such as a computer) to a second external device (such as a monitor, printer, speaker, mobile phone). By connecting the first external device to the hub 2 and the second external device to the hub 2, the first external device can be electrically connected to the second external device. The first external device can provide information or energy input to the circuit board assembly 212 in the hub 2. The information or energy processed by the circuit board assembly 212 is transmitted to the second external device through the hub 2, realizing the transfer function of the hub 2 between the first external device and the second external device. For another example, it can also be that the information or energy of the second external device is transmitted to the circuit board assembly 212 in the hub 2, and the circuit board assembly 212 transmits the information or energy to the first external device.

[0044] The magnetic connection between the first magnetic member 12 and the second magnetic member 22 can make the connection between the hub 2 and the base 1 simple and have strong stability, and it is convenient to fix or disassemble the hub 2 on the base 1. By attracting or separating the first magnetic member 12 and the second magnetic member 22, the quick connection or separation between the hub 2 and the base 1 can be realized.

[0045] The hub 2 is detachably fixed to the base 1. When the hub 2 is fixed to the base 1, the base 1 can provide a stable support and fixing function for the hub 2, facilitating the hub 2 to be fixedly placed at a set position and reducing the possibility of the hub 2 moving due to external forces. When the hub 2 is separated from the base 1, the position of the hub 2 can be adjusted according to the actual needs of the user to meet the user's usage requirements for the hub 2 in different positions.

[0046] For example, the base 1 is fixed to the back of the first external device (such as a computer), which can make full use of space and avoid the base 1 occupying desktop space. The hub 2 is magnetically connected to the base 1 through the first magnetic member 12 and the second magnetic member 22 and thus fixed to the base 1. Further, the hub 2 can be fixed to the back of the first external device, avoiding the hub 2 occupying desktop space. And when multiple external devices are connected to the hub 2, the desktop space occupied by the connecting wires between the multiple external devices and the hub 2 can be reduced, which is beneficial to keeping the desktop tidy.

[0047] For another example, when the user needs to carry the hub 2 or adjust the position of the hub 2, since the hub 2 is detachably fixed to the base 1, separating the first magnetic member 12 and the second magnetic member 22 to release the connection between the hub 2 and the base 1 can facilitate the user to carry the hub 2 or adjust the position of the hub 2 according to actual needs, meeting the user's usage requirements for the hub 2 in different positions.

[0048] Among them, the base 1 further includes an adhesive layer 13, and the adhesive layer 13 is provided on the side of the base body 11 facing away from the hub 2. The adhesive layer 13 can stably fix the base 1 at a set position, reducing the possibility of the base 1 moving due to external force collision.

[0049] For example, the base 1 is fixed to the back of a first external device (such as a computer). By arranging the adhesive layer 13 on the side of the base body 11 facing away from the hub 2, the base 1 can be stably fixed to the back of the first external device. When the hub body 21 and the base body 11 are connected by a first magnetic attraction member 12 and a second magnetic attraction member 22, the hub 2 can be stably fixed to the back of the first external device, reducing the possibility of the hub 2 moving due to external force collision.

[0050] Optionally, the base 1 can be fixed to a set object through the adhesive layer 13. For example, the base 1 can be fixed to the back of a first external device through the adhesive layer 13. The first external device can include a laptop computer, a tablet computer, a monitor of a desktop computer, etc.

[0051] According to the hub assembly 100 of the embodiment of the present utility model, by providing the first magnetic attraction member 12 and the adhesive layer 13 on the base body 11, and the hub 2 being provided with the second magnetic attraction member 22 and the second magnetic attraction member 22 attracting the first magnetic attraction member 12, the hub 2 and the base 1 can be quickly connected or separated. The adhesive layer 13 can stably fix the base 1 at a set position, and when the hub 2 is fixed to the base 1, the hub 2 can be stably fixed at a set position. For example, the base 1 can be fixed to the back of an external device, and further the hub 2 can be stably fixed to the back of the external device, making full use of space to reduce the occupation of desktop space and being beneficial to desktop neatness; moreover, the quick separation between the hub 2 and the base 1 can also facilitate the user to adjust the position of the hub 2 according to actual needs, meeting the user's usage requirements for the hub 2 at different positions.

[0052] Refer to Figure 10 and Figure 15, according to some embodiments of the present utility model, a positioning protrusion 111 is formed on one side of the base body 11 facing the hub 2, and a positioning groove 213 is formed on one side of the hub body 21 facing the base body 11. The positioning protrusion 111 is received in the positioning groove 213. The positioning protrusion 111 can play a role in positioning the assembly between the base body 11 and the hub body 21, ensuring the accurate assembly position between the hub body 21 and the base body 11. The positioning groove 213 can facilitate the accommodation of the positioning protrusion 111 therein, thereby facilitating the assembly between the base body 11 and the hub body 21, and can make the overall structure of the hub body 21 and the base body 11 compact. By the positioning protrusion 111 being received in the positioning groove 213, the positioning groove 213 can play a role in limiting the movement of the positioning protrusion 111, and further enhance the stability of the connection between the base body 11 and the hub body 21, reducing the possibility that the hub 2 body loosens or falls off due to external force when the hub 2 body is fixed to the base body 11.

[0053] Referring to Figure 10 and Figure 15 , according to some embodiments of the present utility model, there are a plurality of positioning grooves 213, and the plurality of positioning grooves 213 are distributed at opposite ends of the hub body 21 along the first direction (for example, it can refer to Figure 1 the e1 direction in Figure 1 ), the positioning groove 213 extends along the second direction (for example, it can refer to Figure 1 the e2 direction in Figure 1 ), the second direction intersects the first direction, and there are a plurality of positioning protrusions 111 and the plurality of positioning protrusions 111 correspond to the plurality of positioning grooves 213 one by one.

[0054] The positioning groove 213 extending along the second direction can ensure the contact area between the positioning groove 213 and the positioning protrusion 111, thereby ensuring the stability of the connection between the hub body 21 and the base body 11. When the hub body 21 is fixed to the base body 11, it can reduce the possibility that the hub body 21 moves relatively along the second direction under the action of external force; moreover, the plurality of positioning grooves 213 are distributed at opposite ends of the base body 11 along the first direction, and the plurality of positioning protrusions 111 correspond to the plurality of positioning grooves 213 one by one, which can further enhance the stability of the connection between the hub body 21 and the base body 11. When the hub body 21 is fixed to the base body 11, it can reduce the possibility that the hub body 21 moves relatively along the first direction under the action of external force.

[0055] The plurality of positioning grooves 213 are distributed at opposite ends of the base body 11 along the first direction, the positioning grooves 213 extend along the second direction, the plurality of positioning protrusions 111 are in one-to-one correspondence with the plurality of positioning grooves 213 respectively, which can enhance the connection stability between the hub body 21 and the base body 11 in multiple directions. When the hub body 21 is fixed to the base body 11, the possibility that the hub body 21 moves relative to the base body 11 along the first direction or the second direction under the action of an external force can be reduced.

[0056] In the description of the present invention, "a plurality of" means two or more.

[0057] Referring to Figure 10 、 Figure 11 and Figure 16 According to some embodiments of the present invention, both the hub 2 and the base 1 extend along the first direction. The plurality of first magnetic members 12 are arranged at intervals along the first direction, and the plurality of second magnetic members 22 are in one-to-one correspondence with the plurality of first magnetic members 12 respectively. The plurality of first magnetic members 12 are arranged at intervals along the first direction, and the plurality of first magnetic members are connected to the plurality of second magnetic members 22 in one-to-one correspondence, which can increase the magnetic contact points between the hub body 21 and the base body 11, thereby enhancing the overall magnetic attraction between the hub 2 and the base 1, and making the connection between the hub body 21 and the base body 11 more stable.

[0058] Moreover, the plurality of first magnetic members 12 are arranged at intervals along the first direction. When the hub body 21 is fixed to the base body 11, the force on the hub body 21 can be evenly distributed to the plurality of first magnetic members 12, preventing a single first magnetic member 12 from being damaged due to excessive weight, thereby affecting the connection stability between the hub body 21 and the base body 11.

[0059] Referring to Figure 10 and Figure 16According to some embodiments of the utility model, the base body 11 includes a base body 112 and a base cover plate 113. The first magnetic member 12 is disposed in a space defined by the base body 112 and the base cover plate 113, which can protect the first magnetic member 12, reduce the impact of the external environment on the first magnetic member 12, and extend the service life of the first magnetic member 12. The hub 2 is suitable for being fixed on the side of the base body 112 away from the base cover plate 113, and the adhesive layer 13 is disposed on the side of the base cover plate 113 away from the base body 112. The adhesive layer 13 can make the base body 11 quickly stick to the set position so that the base body 11 is stably fixed at the set position. The hub 2 can be fixed on the base body 11 through the attraction between the first magnetic member 12 and the second magnetic member 22, thereby realizing that the hub 2 is stably fixed at the set position. The adhesive layer 13 is disposed on the side of the base cover plate 113 away from the base body 112, which can prevent the adhesive layer 13 from interfering with the hub 2.

[0060] For example, when the hub assembly 100 is connected to an external device, the base body 11 can be adhered to the back of the external device through the adhesive layer 13, and the first magnetic component 12 and the second magnetic component 22 can be attracted to fix the hub body 21 on the base body 11, and then the hub 2 can be fixed to the back of the external device, which can prevent the hub 2 from occupying too much desktop space and help keep the desktop tidy; the hub 2 is fixed to the side of the base body 112 facing away from the base cover 113, and the adhesive layer 13 is arranged on the side of the base cover 113 facing away from the base body 112, which can facilitate the hub 2 to be fixed to the base 1 and the base 1 to be fixed to the set position, while avoiding interference between the hub 2 and the adhesive layer 13.

[0061] Reference Figure 16 According to some embodiments of the utility model, a first receiving groove 114 is formed on one side of the base body 112 facing the base cover 113, and the first magnetic component 12 is received in the first receiving groove 114. The first receiving groove 114 can facilitate the assembly of the first magnetic component 12 on the base body 112, and can make the overall structure of the first magnetic component 12 and the base body 112 compact.

[0062] Reference Figure 16 According to some embodiments of the present invention, the first magnetic member 12 is fixed in the first receiving groove 114 by glue dispensing, so that the connection between the first magnetic member 12 and the base body 112 can be simple and have strong stability.

[0063] Reference Figure 16 According to some embodiments of the present invention, a reinforcing rib 115 is provided on one side of the base body 112 facing the cover plate. The reinforcing rib 115 is in a grid shape. The reinforcing rib 115 can improve the overall structural strength of the base body 112 to a certain extent.

[0064] Reference Figure 11 and Figure 13 , according to some embodiments of the present utility model, the housing 211 includes a first housing portion 214 and a second housing portion 215 which are oppositely arranged along the third direction (for example, the e3 direction in Figure 3 can be referred to).

The second magnetic member 22 is disposed in the housing 211 and the second magnetic member 22 is fixed to the second housing portion 215. The second magnetic member 22 being disposed in the housing 211 can play a role in protecting the second magnetic member 22, reducing the influence of the external environment on the second magnetic member 22, and extending the service life of the second magnetic member 22.

[0065] The second housing portion 215 is located on the side of the circuit board assembly 212 close to the base 1, and the second magnetic member 22 is fixed to the second housing portion 215, so that the second magnetic member 22 can be located on the side close to the base 1, which can ensure the magnetic connection between the second magnetic member 22 and the first magnetic member 12, so that the hub body 21 is stably fixed to the base body 11, and prevent the magnetic attraction between the first magnetic member 12 and the second magnetic member 22 from being reduced due to the too large distance between the second magnetic member 22 and the first magnetic member 12, thereby affecting the connection stability between the hub body 21 and the base body 11.

[0066] Reference Figure 11 , according to some embodiments of the present utility model, the second housing portion 215 is provided with a second receiving groove, and the second magnetic member 22 is received in the second receiving groove. The second receiving groove can facilitate the assembly of the second magnetic member 22 on the second housing portion 215, and can make the overall structure of the second magnetic member 22 and the second housing portion 215 compact.

[0067] For example, the second magnetic member 22 is fixed in the second receiving groove by dispensing, which can make the connection manner between the second magnetic member 22 and the second housing portion 215 simple and have strong stability.

The lighting of each lamp body 321 represents a certain progress ratio in the time progress of the display screen of the display terminal to be turned on. For example, the user can judge the time progress status of the display screen of the display terminal to be turned on according to the number of lit lamp bodies 321.

[0074] Refer to Figure 13 and Figure 14 , according to some embodiments of the present utility model, the display progress bar assembly 32 includes a plurality of light-blocking protrusions 322 provided on the lamp board. The plurality of light-blocking protrusions 322 are arranged at intervals along the second direction, and the lamp body 321 is located between two adjacent light-blocking protrusions 322. The light-blocking protrusions 322 can block the light emitted by the lamp body 321 from diverging towards the regions outside the two adjacent light-blocking protrusions 322. The lamp body 321 being located between two adjacent light-blocking protrusions 322 can ensure that the light emitted by each lamp body 321 only propagates to the part between the two adjacent light-blocking protrusions 322, preventing the light emitted by each lamp body 321 from diverging to other regions, enabling the user to clearly distinguish the brightness and position of each lamp body 321, and thus ensuring that the time progress status of the display screen of the display terminal to be turned on can be clearly displayed when the plurality of lamp bodies 321 are lit in sequence.

[0075] For example, the light-blocking protrusions 322 can be black light-blocking foam.

[0076] Refer to Figure 13 and Figure 14 , according to some embodiments of the present utility model, the display progress bar assembly 32 includes a diffuser 323. The diffuser 323 is located between the display bar area 33 and the lamp board. Since the diffuser 323 is located between the display bar area 33 and the lamp board, the diffuser 323 can perform a divergence process on the light emitted by the lamp board, dispersing the light emitted by the lamp board. The light distribution after being diffused by the diffuser 323 is relatively uniform, which can ensure that the display brightness of the display bar area 33 is relatively uniform.

[0077] Refer to Figure 1 and Figure 10, according to some embodiments of the present utility model, the housing 211 includes a housing body 216, a first plug 217 and a second plug 218. The first plug 217 and the second plug 218 are respectively installed at opposite ends of the housing body 216 along the first direction. For example, the housing body 216 may include the above-mentioned first housing portion 214 and second housing portion 215. The first housing portion 214 and the second housing portion 215 are oppositely arranged along the third direction. The first plug 217 and the second plug 218 are respectively installed at opposite ends of the housing body 216 along the first direction. The first direction intersects with the third direction, which can form a sealing structure on the outer peripheral surface of the housing 211, preventing external impurities (such as dust and moisture) from entering the housing 211, thereby protecting the environment inside the housing 211 and being beneficial to extending the service life of the hub assembly 100.

[0078] The first plug 217 is provided with a display bar area 33. The hub body 21 further includes a lens 219. The lens 219 is fixed to the first plug 217 and the lens 219 is opposite to the display bar area 33. The lens 219 being opposite to the display bar area 33 can enable the light emitted from the display bar area 33 to be smoothly transmitted to the outside of the housing 211 through the lens 219, so that the user can see the display content of the display bar area 33 from the outside of the housing 211, and the lens 219 can protect the display bar area 33, reducing the influence of the external environment on the display bar area 33 and extending the service life of the display bar area 33.

[0079] Optionally, the lens 219 can be fixed to the first plug 217 by structural adhesive, which can make the connection between the lens 219 and the first plug 217 simple and have strong stability.

[0080] Referring to Figure 1 and Figure 10 , according to some embodiments of the present utility model, the hub body 21 includes a button 31. The button 31 is provided on the first plug 217 and the button 31 is in electrical contact with the circuit board assembly 212. An avoidance hole 220 for avoiding the button 31 is formed on the lens 219. When the hub 2 is connected to the terminal, the button 31 is used to control the screen off and screen on of the display screen of the terminal. The avoidance hole 220 can facilitate the accommodation of the button 31 therein, facilitating the assembly between the first plug 217 and the lens 219, thereby facilitating the assembly between the housing 211 and the lens 219, and making the overall structure of the housing 211 and the lens 219 compact.
