Description

Technical Field

[0001] The present application relates to the technical field of digital product connection devices, and more specifically, to a desktop HUB. Background Art

[0002] Currently, a hub is usually set on the desktop to store the products on the desktop and keep the desktop beautiful. For example, a HUB is generally set in the conference room to store the screen transmitter and smart pen to avoid loss.

[0003] However, the HUB in the related art usually only serves as a storage device and has low practicality. Summary of the invention

[0004] In order to solve the above problems, the present application provides a desktop HUB. The base in the desktop HUB provided by the present application can store and charge the screen transmitter, thereby improving the practicality of the desktop HUB.

[0005] In the first aspect, the present application provides a desktop HUB, comprising: a base, the base having a first accommodating groove, the first accommodating groove being used to accommodate a screen transmitter; a first power supply module and a first communication module are arranged in the base, the first power supply module and the first communication module are electrically connected, and, after the screen transmitter is placed in the first accommodating groove, the first power supply module is coupled with the first power receiving module in the screen transmitter to supply power to the screen transmitter; the first communication module is used to communicate with the smart blackboard, and is also used to communicate with the second communication module in the screen transmitter.

[0006] In the above technical solution, the desktop HUB provided by the present application can charge the screen transmitter through the first power supply module in the screen transmitter while storing the screen transmitter, thereby improving the practicality of the desktop HUB. Moreover, the desktop HUB provided by the present application is provided with a first communication module, so that the desktop HUB can also identify the identification of the inserted screen transmitter, so that after the screen transmitter is placed in the first receiving slot, it can communicate and connect with the smart blackboard while being charged, and there is no need to operate the screen transmitter separately to make it communicate and connect with different smart blackboards. The operation is simple, and the screen transmission efficiency is high, further improving the practicality of the desktop HUB.

[0007] In a possible implementation, the desktop HUB is provided with at least two first power supply modules at circumferential intervals in the first accommodating groove. After the screen transmitter is received in the first accommodating groove, one of the at least two first power supply modules is used to couple with at least one first power receiving module among the multiple first power receiving modules of the screen transmitter.

[0008] In the above technical solution, after the screen transmitter is placed in the first receiving slot, the screen transmitter can be powered by the first power supply module located at a position corresponding to the first power receiving module, thereby ensuring the reliability of the desktop HUB's power supply to the screen transmitter. For example, when the first surface of the screen transmitter faces the first receiving slot, a first power receiving module at the left position can be coupled with the first power supply module at the left position of the desktop HUB, thereby charging; when the second surface of the screen transmitter faces the first receiving slot, at this time, another first power receiving module at the left position can be coupled with the first power supply module at the left position of the desktop HUB1, thereby charging. Regardless of whether the screen transmitter is placed upright (i.e., the first surface faces the first receiving slot) or reversed (i.e., the second surface faces the first receiving slot), the desktop HUB can charge it, thereby ensuring the charging reliability of the desktop HUB.

[0009] In one possible implementation, the first accommodating groove can accommodate at least two screen transmitters in a stacked manner, and the base has at least two first power supply modules. The two first power supply modules are arranged at intervals along the height direction of the first accommodating groove and correspond one-to-one to the at least two stacked screen transmitters.

[0010] In the above technical solution, the first receiving slot of the desktop HUB can simultaneously receive two screen transmitters, so as to improve the receiving effect of the desktop HUB.

[0011] In a possible implementation, at least two first power supply modules are provided at each layer in the height direction, and the at least two first power supply modules are arranged at intervals along the circumference of the first receiving groove.

[0012] In the above technical solution, on the basis of improving the accommodation effect of the desktop HUB, by arranging at least two power supply modules at intervals in the circumferential direction of each layer, the desktop HUB can charge multiple screen transmitters regardless of whether the multiple screen transmitters are placed upright or inverted, thereby ensuring the charging reliability of the desktop HUB.

[0013] In a possible implementation, the first power supply module includes a power supply coil, and the first power receiving module includes a power receiving coil; after the screen transmitter is placed in the first receiving groove, the power supply coil and the power receiving coil are coupled correspondingly so that the base supplies power to the screen transmitter.

[0014] In the above technical solution, when the screen transmitter is placed in the first receiving groove, the power supply coil can be coupled with the power receiving coil accordingly, so that the base can power the screen transmitter. The wireless charging coil has strong environmental adaptability, and there is no need for direct contact between the power supply coil and the power receiving coil. The power supply coil can charge the power receiving coil with high voltage, high current and high power, ensuring the reliability of the power supply coil charging the power receiving coil, that is, ensuring the charging reliability of the desktop HUB.

[0015] In a possible implementation, a second receiving groove is provided on the base, and the second receiving groove is used to receive the smart pen.

[0016] In the above technical solution, the desktop HUB can not only store and charge the screen transmitter, but also store the smart pen, thereby improving the storage effect of the desktop HUB.

[0017] In a possible implementation, a second power supply module is provided in the base, the second power supply module is electrically connected to the first communication module, and after the smart pen is placed in the second receiving slot, the second power supply module is coupled to the second power receiving module in the smart pen to supply power to the smart pen.

[0018] In the above technical solution, the desktop HUB can not only store the smart pen, but also charge it through the second power supply module. There is no need to set up an additional charging stand for charging the smart pen, which saves costs and further improves the practicality of the desktop HUB.

[0019] In a possible implementation, the second power supply module is located near the bottom of the second receiving groove.

[0020] In the above technical solution, the gravity of the smart pen is toward the base. By setting the second power supply module near the bottom of the second accommodating groove, the second power receiving module and the second power supply module inside the smart pen can be fully coupled under the action of gravity, thereby ensuring the charging reliability of the desktop HUB.

[0021] In a possible implementation, the base further has an avoidance groove, which is connected to the first accommodating groove and runs through the base; the avoidance groove is used to allow the portion of the screen transmitter with a data interface to pass out of the base.

[0022] In the above technical solution, when the screen transmitter is placed in the first accommodating groove, the portion of the screen transmitter with the data interface can pass through the base. In this way, while ensuring that the desktop HUB can store and charge the screen transmitter, it can also ensure that the portion of the screen transmitter with the data interface will not be damaged by the desktop HUB, that is, the reliability of the connection between the screen transmitter and the device to be transmitted is guaranteed.

[0023] In a possible implementation, the base has a power port, and the power port includes at least one of an AC power port and an Ethernet power port.

[0024] In a possible implementation, the base, the screen transmitter, and the smart pen are charged through a resonant wireless charging technology.

[0025] In the above technical scheme, the sizes of the charging coil and the power supply coil of the resonant wireless charging technology can be set according to actual usage requirements. For example, the sizes of the charging coil and the power supply coil can be set smaller to ensure the miniaturization of the desktop HUB, and the setting position of the power supply coil in the base can be customized according to the position of the power receiving coil in different screen transmitters, so that the desktop HUB can accommodate various types of screen transmitters, making the storage range of the desktop HUB wider.

[0036] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, and circuits are omitted to prevent unnecessary details from obstructing the description of the present application.

[0037] In daily work, there are usually many electronic products on the desktop for users to use, such as mobile phones, computers, wireless charging stations, and humidifiers. As the number of electronic products piled on the desktop increases, the desktop becomes messy, aesthetically pleasing, and not conducive to the user's work. At present, a storage device is usually set on the desktop, such as a storage rack, a storage frame, a HUB, etc., to store these electronic products and ensure the aesthetics of the desktop.

[0038] For example, taking a conference room as an example, electronic products such as screen transmitters, computers, and smart pens are generally placed on the desktop of the conference room, where the screen transmitter is used to communicate and connect with the smart blackboard in the conference room, so that users can transmit the displayed image on the computer to the smart blackboard. Due to the large flow of personnel in the conference room, in order to avoid the loss of the screen transmitter and the smart pen, etc., a HUB is usually set on the desktop of the conference room to store the screen transmitter and the smart pen for the convenience of different users. However, the HUB in the related art usually only plays a storage role, does not have functions such as charging, and has low practicality. The screen transmitter is generally equipped with a battery inside, however, the battery capacity is small, and only when the battery is fully charged can it be quickly transmitted with the smart blackboard, that is, it is started within 5S (seconds) and connected to the smart blackboard. In this way, the communication time is slow, and the communication is affected by the battery power and is not stable. Moreover, the screen transmitter needs to communicate and connect with the smart blackboard in the corresponding conference room in order to transmit the screen. However, when the screen transmitter is taken to another conference room for use, it may be possible that the screen transmitter has already been communicated and connected with the smart blackboard in the other conference room, resulting in a mismatch between the transmitted screen and the smart blackboard, or even causing the transmitted screen to be incorrectly displayed on the smart blackboard in the other conference room, causing problems such as screen transmission errors and low screen transmission accuracy.

[0039] To this end, an embodiment of the present application provides a desktop HUB that can store and charge a screen transmitter, thereby improving the practicality of the desktop HUB, and the screen transmitter can be connected to the corresponding smart blackboard through the desktop HUB to ensure the screen transmission accuracy of the screen transmitter.

[0040] The desktop HUB provided by the present application is introduced as an example below in conjunction with the accompanying drawings. It is worth noting that the present application only uses the desktop HUB placed in office scenes such as conference rooms to store and charge screen transmitters, smart pens, etc. The desktop HUB provided by the present application can also be used in other scenes that require storage and charging, and the present application does not make specific restrictions on this.

[0041] like Figure 1 As shown, the desktop HUB1 provided in the embodiment of the present application may include: a base 11, and a first receiving groove (such as Figure 1 11A), the screen transmitter 2 can be placed in the first receiving slot 11A, so that the base 11 can serve as a storage for the screen transmitter 2. In this example, the base 11 is also provided with a first power supply module 111 and a first communication module 112, and the first power supply module 111 and the first communication module 112 are electrically connected. When the screen transmitter 2 is placed in the first receiving slot 11A, the base 11 can supply power to the screen transmitter 2. Here, it is worth noting that a first power receiving module 21 is provided in the screen transmitter 2. When the screen transmitter 2 is placed in the first receiving slot 11A, the first power supply module 111 is coupled with the first power receiving module 21 in the screen transmitter 2 to supply power to the screen transmitter 2, so that the desktop HUB1 can not only serve as a storage for the screen transmitter 2, but also serve as a charging for the screen transmitter 2, thereby improving the practicality of the desktop HUB1.

[0042] Among them, the first communication module 112 can be connected to the smart blackboard for communication, that is, the desktop HUB1 can be connected to the smart blackboard for communication through the first communication module 112. At this time, when the screen transmitter 2 is placed in the first receiving slot 11A, the first communication module 112 will recognize the logo of the screen transmitter 2, that is, at this time, a second communication module 22 is provided in the screen transmitter, and the first communication module 112 is connected to the second communication module 22 for communication, so that the desktop HUB1 can recognize the logo of the screen transmitter 2 and send the logo to the smart blackboard. In this way, the desktop HUB1 can not only store and charge the screen transmitter 2, but also recognize the logo of the placed screen transmitter 2, so that after the screen transmitter 2 is placed in the first receiving slot 11A, it can be connected to the smart blackboard for communication while being charged. There is no need to operate the screen transmitter 2 separately to make it communicate with different smart blackboards. The operation is simple, and the practicality of the desktop HUB1 is further improved. For example, assuming that the screen transmitter 2 is first placed in the desktop HUB1 of the first conference room, the screen transmitter 2 can be paired with the smart blackboard of the first conference room through the desktop HUB1. When the user connects the screen transmitter 2 to the device to be transmitted, the screen transmitter 2 can instantly transmit the screen to the smart blackboard, and the screen transmission efficiency is high. When the user wants to connect it to the smart blackboard in the second conference room, he only needs to place the screen transmitter 2 in the desktop HUB1 in the second conference room so that the screen transmitter 2 can communicate with the smart blackboard in the second conference room. There is no need to manually switch the connection status of the screen transmitter 2. The operation is simple and the screen transmission efficiency is high.

[0043] Optionally, the first communication module 112, the second communication module 22 and the smart blackboard can be connected to each other through near field communication (NFC) technology, with a transmission frequency of 13.56 Hz, or through Bluetooth or Ethernet. It is worth noting that other communication connection methods are also possible, and this application does not make specific restrictions on this.

[0044] When a plurality of first power receiving modules 22 are provided in the screen transmitting device 2, in order to ensure the charging effect of the desktop HUB1 on the screen transmitting device 2, in one example, a plurality of first power supply modules 111 may be provided in the desktop HUB1, for example, Figure 2As shown, two first power supply modules 111 are arranged at intervals in the circumferential direction of the first receiving slot 11A. After the screen transmitter 2 is received in the first receiving slot 11A, the two first power supply modules 111 can be coupled with at least one of the multiple first power receiving modules 21 of the screen transmitter 2, thereby realizing power supply to the screen transmitter 2. In this way, as long as the screen transmitter 2 is placed in the first receiving slot 11A, the screen transmitter 2 can be powered by the first power supply module 111 at the position corresponding to the first power receiving module 21, thereby ensuring the reliability of power supply to the screen transmitter 2 by the desktop HUB1. For example, when the first surface of the screen transmitter 2 faces the first receiving slot 11A, a first power receiving module 21 at the left position can be coupled with the first power supply module 111 at the left position of the desktop HUB1, thereby charging; when the second surface of the screen transmitter 2 faces the first receiving slot 11A, at this time, another first power receiving module 21 at the left position can be coupled with the first power supply module 111 at the left position of the desktop HUB1, thereby charging. In this way, no matter the screen transmitter 2 is placed upright (ie, the first surface faces the first receiving slot 11A) or inverted (ie, the second surface faces the first receiving slot 11A), the desktop HUB 1 can charge it, thereby ensuring the charging reliability of the desktop HUB 1.

[0045] In one example, the first receiving slot 11A of the desktop HUB 1 can simultaneously accommodate multiple screen sharing devices 2 to improve the accommodating effect of the desktop HUB 1. For example, assuming that there are two screen sharing devices 2, Figure 3 As shown, the first accommodating groove 11A can accommodate two screen transmitters 2 in a stacked manner. At this time, the base 11 needs to be provided with at least two first power supply modules 111, and the two first power supply modules 111 are spaced apart along the height direction of the first accommodating groove 11A. When the two screen transmitters 2 are stacked in the first accommodating groove 11A, at least two first power supply modules 111 in the base 11 correspond one-to-one to the two screen transmitters 2, respectively, thereby achieving a charging effect and ensuring the charging reliability of the desktop HUB 1.

[0046] In this example, at least two first power supply modules 111 are provided on each layer in the height direction of the base 11. The two first power supply modules 111 can be arranged at circumferential intervals along the first accommodating groove 11A, so that the desktop HUB1 can charge multiple screen transmitters regardless of whether they are placed upright or inverted, thereby ensuring the charging reliability of the desktop HUB1. The beneficial effects can be referred to the above exemplary description, and will not be elaborated on here.

[0047] Optionally, the depth of the first receiving groove 11A can be set based on the size and number of the screen transmitters 2, and the present application does not impose any specific limitation on this.

[0048] Optionally, the first power supply module 111 can be a power supply coil, and the first power receiving module 21 can be a power receiving coil. When the screen transmitter 2 is placed in the first receiving slot 11A, the power supply coil can be coupled with the power receiving coil accordingly, so that the base 11 supplies power to the screen transmitter 2. The wireless charging coil has strong environmental adaptability, and there is no need for direct contact between the power supply coil and the power receiving coil. The power supply coil can charge the power receiving coil with high voltage, high current and high power, ensuring the reliability of the power supply coil charging the power receiving coil, that is, ensuring the charging reliability of the desktop HUB1. The first power supply module 111 and the first power receiving module 21 can also be charged through contact point contact, and this application does not make specific restrictions on this.

[0049] When multiple screen transmitters 2 are stacked and placed in the first receiving slot 11A, in order to avoid affecting the power supply effect of the desktop HUB1 on a single screen transmitter 2, in one example, the base 11 and the screen transmitter 2 can be charged through resonant wireless charging technology (AirFuel), and the resonant frequency can be 6.78. The size of the charging coil and the power supply coil using the resonant wireless charging technology can be set according to actual use requirements. For example, the size of the charging coil and the power supply coil can be set smaller to ensure the miniaturization of the desktop HUB1, and the setting position of the power supply coil in the base 11 can be customized according to the position of the power receiving coil in different screen transmitters 2, so that the desktop HUB1 can accommodate various types of screen transmitters 2, making the storage range of the desktop HUB1 wider.

[0050] Optionally, in order to further improve the charging reliability of the desktop HUB1 for the screen transmitter 2, the notch shape of the first accommodating slot 11A can be the same as the outer contour shape of the screen transmitter 2 (for example, a circle, a triangle, an irregular trapezoid, etc.). In this way, when the screen transmitter 2 is placed in the accommodating slot 11A, the outer contour of the screen transmitter 2 can be fitted with the inner groove surface of the first accommodating slot 11A, so that the first power supply module 111 is in full contact with the first power receiving module 21, thereby ensuring the charging stability between the first power supply module 111 and the first power receiving module 21, that is, ensuring the charging reliability of the desktop HUB1 for the screen transmitter 2.

[0051] Here, it is worth mentioning that when the size of the desktop HUB 1 is relatively large, a plurality of first accommodating slots 11A may be provided so that the desktop HUB 1 can accommodate more screen transmitters 2 . This application does not impose any specific limitation on this.

[0052] Since the periphery of the screen transmitting device 2 is usually provided with a data interface for connecting to the device to be transmitted, such as a Universal Serial Bus (USB) interface, when the user wants to place the screen transmitting device 2 in the first receiving slot 11A, in order to avoid the desktop HUB1 damaging its USB interface, or the USB interface protruding so that the screen transmitting device 2 is difficult to place in the desktop HUB1. In one example, Figure 4 As shown, a USB interface 23 is provided at one end of the screen transmitter 2. At this time, an avoidance groove (such as Figure 4 As shown in Figure 11C, the avoidance groove 11C is connected to the first receiving groove 11A and is arranged through the base 11. When the screen transmitter 2 is placed in the first receiving groove 11A, the USB interface 23 of the screen transmitter 2 can pass through the base 11. In this way, while ensuring that the desktop HUB1 can store and charge the screen transmitter 2, it can also ensure that the USB interface 23 of the screen transmitter 2 will not be damaged by the desktop HUB1, that is, the connection reliability between the screen transmitter 2 and the device to be transmitted is guaranteed.

[0053] Optionally, the width of the avoidance groove 11C can be set according to the outer diameter of the USB interface 23, and the present application does not impose any specific limitation on this.

[0054] In one example, if Figure 5 As shown, the base 11 may also be provided with a second receiving groove (such as Figure 5 11B), the second receiving slot 11B can be used to store other electronic products. The following is an exemplary introduction using the electronic product as a smart pen 3. In this example, a second power supply module 113 can be provided in the base 11, and the second power supply module 113 is electrically connected to the first communication module 112. When the smart pen 3 is placed in the second receiving slot 11B, the second power supply module 113 is coupled with the second power receiving module 31 in the smart pen 3, so that the desktop HUB1 can supply power to the smart pen 3. In this way, the desktop HUB1 can not only store and charge the screen transmitter 2, but also store and charge the smart pen 3, without the need to set up an additional charging stand for charging the smart pen 3, which saves costs and further improves the practicality of the desktop HUB1.

[0055] Here, it can be understood that the setting position of the second power supply module 113 can be set correspondingly according to the position of the second power receiving module 31 in the smart pen 3. Figure 5As shown, the second power receiving module 31 is arranged at the bottom of the smart pen 3 away from the pen tip, and the second power supply module 113 can be arranged at a position close to the bottom of the second receiving slot 11B. When the smart pen 3 is placed in the second receiving slot 11B, the second power receiving module 31 and the second power receiving module 31 are coupled to realize charging. At this time, the gravity of the smart pen 3 is toward the base 11. By arranging the second power supply module 113 at a position close to the bottom of the second receiving slot 11B, the second power receiving module 31 and the second power supply module 113 inside the smart pen 3 can be fully coupled under the action of gravity, thereby ensuring the charging reliability of the desktop HUB 1. When the second power receiving module 31 is arranged at a circumferential position of the smart pen 3, the second power supply module 113 can also be arranged correspondingly at the circumference of the second receiving slot 11B. This application does not impose any specific restrictions.

[0056] In order to further improve the storage effect of the desktop HUB1, in one example, Figure 6 As shown, two second receiving slots 11B may be provided on the base 11 to accommodate more smart pens 3. It is worth noting that when the size of the desktop HUB 1 is large, multiple second receiving slots 11A may be provided so that the desktop HUB 1 can accommodate more smart pens 3, and this application does not make any specific restrictions on this.

[0057] Optionally, the second power supply module 113 may be a power supply coil, and the second power receiving module 31 may be a power receiving coil, which will not be described in detail.

[0058] In one example, a power port may be provided on the base 11, and the power port may include at least one of an AC power port and an Ethernet power port, so that the base 11 can charge electronic products such as the screen transmitter 2 and the smart pen 3.

[0059] The desktop HUB1 provided by the present application can store the screen transmitter 2 and the smart pen 3, and can charge the screen transmitter 2 and the smart pen 3 through the first power supply module 111 and the second power supply module 113 in the screen transmitter 2, thereby improving the practicality of the desktop HUB1. In addition, the desktop HUB1 provided by the present application is provided with a first communication module 112, so that the desktop HUB1 can also identify the identification of the inserted screen transmitter 2, so that after the screen transmitter 2 is placed in the first receiving slot 11A, it can communicate and connect with the smart blackboard while being charged, and there is no need to operate the screen transmitter 2 separately to make it communicate and connect with different smart blackboards. The operation is simple, and the screen transmission efficiency is high, further improving the practicality of the desktop HUB1.
