Description

Technical Field

[0001] The utility model relates to the technical field of display heightening frames, in particular to an intelligent heightening frame. Background Art

[0002] People frequently use monitors in their daily life and work. The tables used to place monitors are generally not very high. After the monitor is placed on the table, the height of the middle of the monitor display interface is basically level with or slightly lower than the eye height of the people sitting in front of the table. This makes people often lower their heads to operate the corresponding monitor. When people lower their heads to the corresponding monitor for a long time, it is easy to cause stiffness and spasm of the neck and shoulder muscles, and cause soreness and swelling of the cervical spine or even cervical instability.

[0003] Therefore, in order to solve the above problems, a monitor heightening rack has emerged. The common monitor heightening racks on the market basically include a monitor placement table and two heightening legs for supporting the corresponding monitor placement table. The two corresponding heightening legs are fixedly arranged at the left and right ends of the corresponding monitor placement table. Some high-end monitor heightening racks will have an expansion dock on one of the heightening legs. The expansion dock can be used to expand the USB interface of the computer host, so that USB devices can be easily connected. For example, a light bar that can be connected to a USB interface can be used to fill in the surrounding environment. It can also be connected to electronic devices such as mobile phones, so as to facilitate charging of mobile phones and other electronic devices.

[0004] However, the existing expansion docks for display racks usually only have simple USB expansion functions and cannot meet the user's intelligent control needs. Utility Model Content

Since the light control circuit is provided in the light control device, the user's language signal can be obtained through the voice recognition module in the light control circuit, and the corresponding voice control instruction can be obtained through the obtained voice signal. After obtaining the corresponding voice control instruction, the voice recognition module can communicate with the main control circuit module through the VC_U2TXD and VC_U2RXD signal terminals. The main control circuit module may include a controller U16, and the controller U16 may be connected to the light bar control module through the RGBIC_DAT signal terminal to output the light color adjustment control signal to the light control circuit, because the light control circuit is connected to the light bar. In this way, the light control circuit can drive the light bar to emit light according to the light color adjustment control signal, and adjust the light bar to the color controlled by the user through the language instruction. In this way, the display color of the light bar can be controlled by voice, making it more convenient for the user to change the light color of the light bar.

[0053] See also Figure 5 The light bar control module includes: a first USB connector and a light bar power supply control circuit, wherein the first USB connector is connected to the light bar; the light bar power supply control circuit is respectively connected to a power supply, a power supply end of the first USB connector and the voice recognition module, and the voice recognition module is also used to control the light bar power supply control circuit according to the voice control instruction, so as to control the light bar to light up or extinguish through the light bar power supply control circuit.

This facilitates the connection with the light bar of the Type-A USB interface. Data can be sent to the light bar through the first USB connector USBA4 to control the luminous color of the light bar. In addition, the light bar can be powered by the first USB connector USBA4, so that the light bar does not need to be connected to an external power supply. The power supply of the lamp body can be turned on or off through the voice recognition module and the light bar power supply control circuit. In this way, the user can control the power supply of the light bar by voice. This makes it more convenient for the user to change the light bar on and off.

[0054] like Figure 5As shown in, the light bar power supply control circuit includes: a first MOS tube Q2 and a second MOS tube Q11, the source of the first MOS tube Q2 is connected to the power supply, the source of the first MOS tube Q2 is also connected to the gate of the first MOS tube Q2 through a resistor, and the drain of the first MOS tube Q2 is connected to the power supply end of the first USB connector; the drain of the second MOS tube Q11 is connected to the gate of the first MOS tube Q2, the source of the second MOS tube Q11 is connected to the reference ground, the gate of the second MOS tube Q11 is connected to the reference ground through a first resistor R51, and the gate of the second MOS tube Q11 is also connected to the power supply control end of the voice recognition module light bar.

[0055] Specifically, the working process of the light bar power supply control circuit is as follows: when the user needs to light up the light bar, the voice recognition module can be awakened by voice, and a voice control signal for lighting up the light bar can be sent. After the voice recognition module obtains the language control signal sent by the user, it can recognize the voice control signal. After correct recognition, a high-level signal can be output through PWRCTL_LIGHT. The high-level signal can turn on the second MOS tube Q11 and the first MOS tube Q2 at the same time. The DC power supply DC_IN can be output through the first MOS tube Q2, and output to the power supply of the first USB connector USBA4 through the DC_LIGHT power signal terminal, and the light bar is powered through the first USB connector USBA4. On the contrary, when the user needs to turn off the light bar, the voice recognition module can be awakened by voice, and a voice control signal for turning off the light bar can be sent. After the voice recognition module obtains the language control signal sent by the user, it can recognize the voice control signal. After correct recognition, it can output a low-level signal through PWRCTL_LIGHT, which can turn off the second MOS tube Q11 and the first MOS tube Q2, disconnect the DC power supply DC_IN, and the first USB connector USBA4 has no power output. The light bar is turned off due to the lack of power supply. Therefore, the light bar can be turned on and off by language, making it more convenient for users to change the light bar on and off.

[0059] Specifically, Fig. 9 As shown in , the enable end of the power converter U6 is connected to the control end of the voice recognition module through PWRCTL_PD, so that the power supply of the power converter U6 can be controlled by the voice recognition module. For example, when the user needs to control the switch of the fast charging power supply of the fast charging interface USBC2, the voice recognition module can be awakened by voice, and a fast charging power switch voice control signal is issued. After the voice recognition module obtains the language control signal issued by the user, the voice control signal can be recognized. After correct recognition, the control signal can be output through the PWRCTL_PD signal end, and the power conversion control of the power converter U6 can be performed through the PWRCTL_PD signal end.
