By duplicating or expanding the laptop's ports, it allows the laptop to connect to multiple accessories or external devices. To meet diverse user needs, docking stations are often equipped with an LCD (Liquid Crystal Display).

[0003] However, in the related art, the display direction of the fixed display screen on the expansion dock is fixed. When the user uses the expansion dock in multiple scenarios, it is not conducive for the user to view the relevant information of the connection interface displayed on the expansion dock display screen. Utility Model Content

[0006] The docking station described above includes a rotation detection device in its housing that is electrically connected to a processing device. The processing device is also connected to a display device. During user use, if the spatial position of the docking station rotates relative to a previous period or moment, this rotation detection device can detect it. The rotation detection device then collects rotational state parameters related to the docking station's rotation and transmits them to the processing device. After receiving the rotational state parameters, the processing device analyzes them and generates a display adjustment signal to adjust the display content of the display device to facilitate user viewing when the docking station is in the rotated state.

[0016] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0017] The docking station provided in this application is specifically a docking station equipped with a display device. Through the display device, device status, data information, images, videos, and other content can be viewed intuitively. It should be noted that the type of display device configured in the docking station is not limited to a single type. It can be an LCD (Liquid Crystal Display), an LED (Light Emitting Diode) display, an OLED (Organic Light-Emitting Diode) display, etc., without specific limitation. To facilitate understanding of the technical solution of this application, the display device in the following embodiments can be understood to be an LCD.

[0018] See also Figure 1 The present application provides a docking station, comprising at least one interface component 200, a housing 10, a rotation detection device 20, a processing device 30, and a display device 40. The outer surface of the housing 10 is provided with at least one expansion socket, that is, the docking station may include one interface component 200 or multiple interface components 200. Figure 1 Take the expansion dock including three interface components 200 as an example, the interface components 200 are arranged in the housing 10, and the interface ends of each interface component 200 extend to an expansion socket in a one-to-one correspondence. Figure 1 That is, the expansion dock includes three expansion sockets, and each expansion socket is connected to each interface component 200 in a one-to-one correspondence.

[0019] The rotation detection device 20 is arranged in the shell 10, and the rotation detection device 20 is used to obtain the rotation state parameters of the expansion dock when the expansion dock rotates; the processing device 30 is arranged in the shell 10, and the processing device 30 is electrically connected to the rotation detection device 20, and the processing device 30 is used to receive the rotation state parameters and output a display adjustment signal; wherein, the display adjustment signal is determined according to the rotation state parameters, and the display adjustment signal includes the rotation angle of the display content, and the rotation angle of the display content corresponding to different rotation state parameters is different; the display device 40 is arranged in the shell 10, and the display device 40 is partially exposed on the outer surface of the shell 10, the display device 40 is electrically connected to the processing device 30, and the display device 40 is used to adjust the display angle of the display content according to the display adjustment signal.

[0020] Specifically, the shell 10 is the outer shell of the docking station, which is used to accommodate and carry other components of the docking station, and also plays a protective role. The interface component 200 is a device used to implement the interface expansion function. The rotation detection device 20 is a device provided in the docking station, which can change its own parameters as the position and posture of the docking station changes in different usage scenarios, thereby detecting the rotation state of the docking station. The processing device 30 is a device with data receiving and sending and data processing functions. The display device 40 is a device used to display the status of the connected device of the docking station, the data information of the interface connection, or images and videos, etc., which can be a liquid crystal display screen, etc.

[0021] The rotation state parameter is a parameter representing the real-time position of the docking station as captured by the rotation detection device 20 when the docking station rotates. The type of rotation state parameter is not unique; it may vary depending on the type of rotation detection device 20. For example, in one embodiment, the rotation state parameter may be spatial position coordinate data captured by the rotation detection device 20. The display adjustment signal carries parameters such as the rotation angle of the display device 40 that need to be adjusted to make the display content more convenient for the user to view when the docking station rotates.

[0022] During use of the docking station, the rotation detection device 20 performs real-time rotation detection of the docking station. When the docking station rotates, it causes a change in its spatial position. The rotation detection device 20 detects this change, obtains a rotation state parameter, and transmits it to the processing device 30. After receiving the rotation state parameter, the processing device 30 analyzes it in conjunction with the rotation state parameter to ultimately determine the current state of the docking station relative to its original horizontal position. The processing device 30 then generates the display adjustment signal required by the display device 40, which is then transmitted to the display device 40 to rotate the display angle of the displayed content.

[0023] It should be noted that the size of the display content rotation angle is not unique and is not limited to the conversion between horizontal and vertical screen display. In one embodiment, the display content rotation angle is greater than 0 degrees and less than or equal to 360 degrees. That is, the display content of the display device 40 can be adjusted from 0 to 360 degrees based on the initial display direction, thereby meeting the needs of various combinations of docking station placement scenarios. Among them, this application does not limit the initial display direction. The initial display direction can be horizontal horizontal display or horizontal vertical display, or it can be a direction with a certain angle to the horizontal horizontal direction.

[0024] In addition, it is understandable that according to ordinary people's observation habits, the displayed content is usually displayed in accordance with visual and reading habits, that is, the displayed content needs to be parallel to the horizontal plane as much as possible. Therefore, this application does not make any limitation.

[0025] Specifically, the processing device 30 determines the display adjustment signal based on the rotation state parameter, including: determining a posture change parameter based on the rotation state parameter; and analyzing the posture change parameter to determine the display adjustment signal. The posture change parameter represents the amount of change in spatial position caused by the rotation of the dock, i.e., the posture change amount.

[0026] It can be understood that in one embodiment, after the processor receives the rotation state parameter, it will determine whether the rotation state parameter is received normally. If it is determined that the rotation state parameter is received normally, it will then execute the step of determining the posture change parameter based on the rotation state parameter.

[0027] There is no single method for determining whether the rotation state parameter is received normally. Specifically, in one embodiment, the method can be implemented by verifying the address carried by the rotation state parameter and the data range within which the rotation state parameter is located. For example, if the address carried by the rotation state parameter is verified to be normal and the numerical range of the rotation state parameter is within a preset numerical range, the rotation state parameter is considered to be received normally.

[0028] Meanwhile, in the case that the rotation state parameters are not received normally, the collection of the rotation state parameters is repeatedly performed until the rotation state parameters are received normally.

[0029] In one embodiment, if the reception of multiple rotation state parameters is abnormal, a prompt signal may be outputted to prompt the user that the data reception is abnormal.

[0030] It should be noted that, in one embodiment, the processing device 30 may be a main controller for performing interface expansion in the docking station, i.e., the display processing and interface expansion of the docking station share a single device. This can save equipment costs and reduce equipment size.

[0031] In another embodiment, the processing device 30 can also be a separate device from the main controller of the docking station, that is, the interface expansion and display processing of the docking station are implemented by different devices. In this way, the data processing pressure of the main controller of the docking station is effectively relieved, and the operating efficiency of the docking station is improved.

[0032] To facilitate understanding of the technical solution of this application, the following embodiments are explained using an example in which display processing and interface expansion share a single device. The specific type of processing device 30 is not limited to a single device. In one embodiment, it can be an MCU (Microcontroller Unit), a CPU (Central Processing Unit), or a single-chip microcomputer, etc., without limitation.

[0033] The docking station described above has a rotation detection device 20 provided within its housing 10, electrically connected to a processing device 30. The processing device 30 is also electrically connected to a display device 40. During user use, if the spatial position of the docking station rotates relative to a previous period or moment, this rotation detection device 20 can detect the rotation. At this point, the rotation detection device 20 collects rotational state parameters related to the docking station's rotation and transmits them to the processing device 30. After receiving the rotational state parameters, the processing device 30 analyzes them and obtains a display adjustment signal for adjusting the display content of the display device 40 to facilitate user viewing of the displayed content in the rotated state. Finally, the display device 40 adjusts the display angle of its displayed content based on the display content rotation angle carried by the display adjustment signal. This allows the displayed content on the docking station to adapt to the user's viewing habits and facilitate viewing when the user uses the docking station in multiple scenarios. With this solution, if the user rotates the docking station at multiple angles during use, the displayed content on the docking station can adapt to the docking station's rotation and change in real time, effectively improving the user's convenience in viewing information when using the docking station.

[0034] It should be pointed out that the manner in which the above-mentioned interface component 200, the rotation detection device 20 and the processing device 30 are arranged in the shell 10 is not the only one. In one embodiment, the interface component 200, the rotation detection device 20 and the processing device 30 can be directly in contact with the shell 10 and arranged on the inner surface of the shell 10, and the devices that need to be electrically connected are connected through line routing.

[0035] In another embodiment, see Figure 2A circuit substrate 100 may also be disposed within the housing 10. The interface assembly 200, the rotation detection device 20, and the processing device 30 may all be disposed on the circuit substrate 100, or connected to the circuit substrate 100, with wiring arranged through the circuit substrate 100 to achieve electrical connection between the components. The first communication device, the second communication device, and the low-dropout linear regulator involved in the following embodiments may also be electrically connected to or disposed on the circuit substrate 100 in a similar manner, and the details will not be repeated here.

[0036] See also Figure 3 In one embodiment, the docking station further includes a first communication device 50 , which is disposed in the housing 10 , and the rotation detection device 20 is electrically connected to the processing device 30 via the first communication device 50 .

[0037] Specifically, the first communication device 50 is a device used to implement communication between the rotation detection device 20 and the processing device 30. In actual detection scenarios, the communication protocols between the rotation detection device 20 and the processing device 30 may be inconsistent. To achieve reliable transmission of rotation state parameters, the first communication device 50 is configured between the rotation detection device 20 and the processing device 30. Protocol conversion is performed by the first communication device 50, thereby improving the transmission reliability of the rotation state parameters.

[0038] It should be noted that the type of the first communication device 50 is not unique and may vary depending on the type of the rotation detection device 20 or the processing device 30. For example, in one embodiment, the first communication device 50 is an IIC (Inter-Integrated Circuit) communication module.

[0039] Specifically, an I2C communication module, also known as an I2C communication module, utilizes the I2C communication protocol for data transmission. Specifically, the rotation detection device 20 communicates with the processing device 30 via the SDA and SCL pins of the I2C communication module, providing real-time rotation state parameters. This solution, employing an I2C communication module as the first communication device 50, enables both low-speed and high-speed data transmission, offering high versatility.

[0040] See also Figure 4 In one embodiment, the docking station further includes a second communication device 60 , which is disposed in the housing 10 , and the processing device 30 is electrically connected to the display device 40 via the second communication device 60 .

[0041] Specifically, the second communication device 60 is a device used to implement communication between the display device 40 and the processing device 30. In actual detection scenarios, there may be a mismatch in the communication protocols between the display device 40 and the processing device 30. To ensure reliable transmission of the display adjustment signal, the second communication device 60 is provided between the display device 40 and the processing device 30. Protocol conversion is performed by the second communication device 60, thereby improving the transmission reliability of the display adjustment signal.

[0042] It should be noted that the type of the second communication device 60 is not unique and can be the same as or different from the first communication device 50. Furthermore, the second communication device 60 may also differ depending on the type of the display device 40 or the processing device 30, although this is not specifically limited. For example, in one embodiment, the second communication device 60 is an SPI (Serial Peripheral Interface) communication module or a MIPI (Mobile Industry Processor Interface) communication module.

[0043] Specifically, an SPI communication module uses the SPI protocol for data transmission. A MIPI communication module uses the MIPI protocol for data transmission. The SPI communication module uses four signal lines (SCLK, MOSI, MISO, and CS) to achieve data transmission and control, offering flexibility and adjustable speed. The MIPI communication module supports high-speed serial data transmission, meeting the performance requirements of docking stations. It can be expanded to even higher data transmission rates, making it more suitable for high-resolution LCDs. In practical scenarios, the specific communication module used to enable communication between the processing device 30 and the physical device is not specified here.

[0044] Furthermore, in other embodiments, the second communication device may also be an RS-232 communication module, an RS-485 communication module, an LVDS (Low-Voltage Differential Signaling) communication module, etc., and the selection may be made based on the actual scenario.

[0045] See also Figure 5 In one embodiment, the docking station further includes a low-voltage difference linear regulator 70, which is disposed in the housing 10, and is electrically connected to the rotation detection device 20, and is used to connect to an external power supply (not shown).

[0046] Specifically, the low-dropout regulator (LDO) 70 is an integrated circuit regulator that can stabilize the output voltage when the input-output voltage difference is small. It is a type of linear DC regulator and has a lower input-output voltage difference requirement than traditional linear regulators.

[0047] In actual scenarios, in order to realize power supply of the rotation detection device 20 , a low voltage difference linear regulator 70 is also configured to perform power conversion, thereby providing a stable DC voltage for the rotation detection device 20 to ensure the working stability of the rotation detection device 20 .

[0048] It should be noted that the type of low-dropout linear regulator 70 is not limited to a single type. Depending on the operating voltage of the rotation detection device 20, the low-dropout linear regulator 70 may vary, and this is not specifically limited. For example, in one embodiment, the low-dropout linear regulator 70 is a 3.3V (volt) LDO, i.e., a low-dropout linear regulator 70 capable of outputting a 3.3V DC voltage.

[0049] It is understandable that the specific type of the rotation detection device 20 is not limited. Any device that can detect the position change of an object in space can be used. For example, in one embodiment, the rotation detection device 20 includes an accelerometer and / or a gyroscope.

[0050] Specifically, an accelerometer, or acceleration sensor, is configured in the dock (specifically, it can be disposed within housing 10). When the dock rotates, it can detect changes in acceleration in three dimensions. The accelerometer can sense the dock's acceleration in the X, Y, and Z directions and transmit this data to processing device 30 in the form of three-dimensional spatial coordinates (i.e., rotational state parameters). A gyroscope can detect changes in the dock's angular velocity, i.e., its rotational motion, in real time. The gyroscope provides data regarding the dock's rotational direction and speed (i.e., rotational state parameters) to enable processing device 30 to perform display adjustment analysis on display device 40.

[0051] It is understood that in actual scenarios, either an accelerometer or a gyroscope can be used as the rotation detection device 20 to detect the rotation of the docking station, which can effectively reduce hardware costs. In other embodiments, both an accelerometer and a gyroscope can be used to detect the rotation of the docking station. Combining the detection results of the two can provide a more accurate understanding of the docking station's posture changes, thereby improving the display adjustment accuracy of the display device 40.

[0052] In one embodiment, the rotation detection device 20 is an inertial measurement unit.

[0053] Specifically, the inertial measurement unit (IMU) is a measurement device that integrates an accelerometer and a gyroscope. Unlike the aforementioned embodiment, in which the accelerometer and gyroscope are separately disposed within housing 10, this embodiment utilizes an IMU that integrates an accelerometer and a gyroscope as rotation detection device 20. This achieves accurate posture change detection while also reducing the device size to a certain extent.

[0054] It should be noted that there is no single type of inertial measurement unit (IMU), and any device that integrates both an accelerometer and a gyroscope can be used. For example, in one embodiment, the IMU can be a motion processing unit (MPU) such as the MPU-6050, ICM-20602, MPU-6000, or MPU-9250 that has multi-axis accelerometer and gyroscope functionality.

[0055] It can be understood that in one embodiment, the rotation detection device 20 has two detection functions of an accelerometer and a gyroscope. Correspondingly, the processing device 30 analyzes and determines the posture change parameters based on the rotation state parameters, including: first, analyzing the acquired rotation state parameters (including three-dimensional spatial acceleration data detected by the accelerometer and three-dimensional spatial angular velocity data detected by the gyroscope) to determine the time step; then, integrating the angular velocity data and the time step, and integrating the acceleration data and the time step to obtain the corresponding posture parameters respectively.

[0056] After that, a fusion algorithm is used to analyze the posture parameters and finally obtain the posture change parameters. Specifically, the fusion algorithm can be a Kalman filter, a complementary filter, etc., which is not limited here.

[0057] In more detail, in one embodiment, using the complementary filter fusion algorithm as an example, when the docking station is turned on, the processing device 30 first initializes the rotation detection device 20, the first communication device 50, and the second communication device 60. After the initialization process is successful, the processing device 30 configures the initial parameters and the complementary filter coefficient alpha required for the subsequent fusion algorithm. Accordingly, the fusion algorithm is used to analyze the posture parameters, including:

[0058] theta=alpha*(theta+ω*Δt)+(1-alpha)*theta_acc

[0059] Among them, theta represents the attitude change parameter obtained after complementary filtering (specifically, it can be an angle parameter), alpha represents the complementary filter coefficient, which usually takes a value between 0 and 1 and is used to balance the weights of the gyroscope and accelerometer; * represents multiplication, ω represents the angle measured by the gyroscope, Δt represents the step size, and theta_acc represents the angle obtained by converting the unit of the accelerometer part through the inverse tangent function.

[0060] Finally, after obtaining the posture change parameter, the processing device 30 converts it into a display direction angle, and sends it to the display device 40 via a display adjustment signal, thereby causing the display device 40 to adjust the display direction.

[0061] It is understood that the interface component 200 is not limited to a single type, and may vary depending on the actual usage scenario. For example, in one embodiment, the interface component 200 includes at least one of a data transmission interface component, a video transmission interface component, a network interface component, and a charging interface component.

[0062] Specifically, the data transmission interface component is an interface component used to perform the data transmission function, the video transmission interface component is an interface component used to access the display device 40 to realize the video transmission function, the network interface component is an interface component used to access the network, and the charging interface component is an interface component used to access the power supply to realize power transmission.

[0063] In actual scenarios, the expansion dock can be configured with one or more of the data transmission interface components, video transmission interface components, network interface components and charging interface components. In addition, the number of each interface component is not limited to one, and the selection is made based on actual needs.

[0064] The data transmission interface component is not limited to a single type and can include Type-A, Type-C, an SD / TF card reader, and the like. Type-A and Type-C are primarily used to connect to various USB (Universal Serial Bus) devices. Accordingly, the data transmission interface component includes a connected interface and a USB hub chip, which is connected to the docking station's main controller, specifically the aforementioned processing device 30. The video transmission interface component can be an HDMI (High Definition Multimedia Interface) interface component, which includes a connected interface and a video conversion chip, which is connected to the docking station's main controller.

[0065] The network interface component can be a gigabit network port, which is used to provide a wired network connection to ensure more stable and faster network transmission. It includes a connected interface and an Ethernet controller chip, which is further connected to the main controller of the docking station. The charging interface component is mainly used for charging. For example, it can be a PD fast charging port, which includes a connected interface and a PD controller. The PD controller is further connected to the main controller of the docking station.

[0066] In order to facilitate understanding of the technical solution of the present application, the present application is explained below in conjunction with more detailed embodiments.

[0067] In this embodiment, the docking station includes a circuit substrate 100, an interface assembly 200, a housing 10, a rotation detection device 20, a processing device 30, a display device 40, a first communication device 50, a second communication device 60, and a low-voltage dropout linear regulator 70. The low-voltage dropout linear regulator 70 is a 3.3V low-voltage dropout linear regulator 70. The specific structure can be found in Figure 6 The rotation detection device 20 is an inertial measurement unit (specifically, MPU-6050 is used as an example). The specific structure can be found in Figure 7 The first communication device 50 is an IIC communication module, and the specific structure can be found in Figure 8 ; The second communication device 60 is an SPI communication module, and the display device 40 is an LCD.

[0068] The rotation detection device 20 communicates with the processing device 30 via the IIC interface (SDA, SCL), providing real-time acceleration and angular velocity data (i.e., rotation state parameters). A 3.3V LDO provides operating voltage to the MPU-6050. VCC and GND are connected to the 5V power supply and ground, respectively. SCL, SDA, and XCL, XDA are two IIC communication buses. ADO is the slave address setting pin for the IIC communication module, and INT is the interrupt output pin.

[0069] During use, the processor first initializes the MPU-6050 and SPI communication module. After successful initialization, it configures the initial parameters and complementary filter coefficient alpha required for operation. The MPU-6050 then acquires data, obtaining acceleration data from the accelerometer and angular velocity data from the gyroscope (i.e., rotational state parameters), and determines whether the data has been successfully received. Specifically, this is achieved by address verification and checking whether the received data is within a preset value range.

[0070] After determining that the reception is successful, the processing device 30 calculates the time step Δt, performs integral calculations based on the acceleration data and the angular velocity data, and obtains the corresponding attitude parameters, that is, the angle theta_acc obtained after the accelerometer part converts the unit through the inverse tangent function, and the angle measured by the gyroscope, and substitutes them into theta=alpha*(theta+ω*Δt)+(1-alpha)*theta_acc for fusion analysis to obtain the attitude change parameters, and converts them into the display content rotation angle required to be adjusted by the display device 40.

[0071] Finally, processing device 30 transmits the displayed content rotation angle (carried by the display adjustment signal) to display device 40, causing display device 40 to change its display orientation. Simultaneously, the MPU-6050 performs the next data acquisition step. Based on the real-time data collected, it returns to the step of determining whether the data was successfully received, repeatedly analyzing the posture change parameters, and achieving real-time adjustment of the display orientation of display device 40 until the docking station is finally deactivated.

[0072] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0073] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
