Description

Technical Field

[0002] A hub (or docking station) is a multi-functional expansion device that provides various ports for different electronic devices to connect and achieve corresponding expansion functions.

[0003] In related technologies, when multiple electronic devices are connected to the docking station, power consumption increases, which in turn causes the docking station to overheat. However, current docking stations often suffer from poor heat dissipation, which not only affects the normal use of the docking station's functions but also reduces its lifespan.

[0029] In the description of this disclosure, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this disclosure.

[0030] It should be understood that in the description of the embodiments of this disclosure, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first," "second," etc., are used in the description, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0031] In the description of the embodiments of this disclosure, unless otherwise expressly limited, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in the embodiments of this disclosure in conjunction with the specific content of the technical solution.

[0032] In the description of this disclosure, references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] As a multi-functional expansion device, a docking station can connect to network ports, card readers, video cables, audio cables, PD fast charging cables, USB flash drives, hard drives, and other electronic devices, as well as large-capacity solid-state drives. Therefore, its power consumption is very high. Combined with its enclosed design, this leads to severe overheating; the surface temperature of the aluminum casing can reach over 55 degrees Celsius, making it extremely hot to the touch and difficult for users to operate. Overheating issues consistently account for a high percentage of returns and customer complaints. Therefore, current docking stations often suffer from poor heat dissipation, which not only affects the normal operation of the docking station but also reduces its lifespan.

[0034] Based on this, the present disclosure proposes an expansion dock with heat dissipation function, which can improve the heat dissipation effect of the expansion dock, ensure the normal use of the expansion dock function, and extend the service life of the expansion dock.

[0035] Reference Figure 1 As shown, Figure 1 This is a functional module diagram of the expansion dock provided in an embodiment of the present disclosure. The expansion dock includes:

[0036] Dock body;

[0037] Temperature detection module, which is installed inside the dock;

[0038] The heat dissipation module is housed within the dock.

[0039] The control module is located inside the dock. The control module includes a voltage detection unit, an input terminal, and an output terminal. The voltage detection unit is electrically connected to the input terminal, the input terminal is electrically connected to the temperature detection module to collect the first electrical signal from the temperature detection module, and the output terminal is electrically connected to the heat dissipation module.

[0040] The control module is used to output a second electrical signal of different magnitude to the heat dissipation module through the output terminal according to the magnitude of the first electrical signal detected by the voltage detection unit.

[0041] In this embodiment of the disclosure, the dock body is the foundation of the entire expansion dock's outer shell and internal structure. It contains the expansion dock's related components, such as ports, circuit boards, and other modules, and provides space for the installation and protection of other modules and units.

[0042] The temperature detection module is located inside the dock and is primarily used to detect the temperature inside the expansion dock or at relevant locations. Further, the temperature detection module may include a thermistor or other temperature sensors, whose electrical characteristics change with temperature; for example, the resistance of a thermistor changes with temperature. When the temperature inside the expansion dock changes, the temperature detection module can sense this change and convert it into an electrical signal, obtaining the first electrical signal. For example, when the temperature rises, the resistance of the thermistor changes, causing a change in the current passing through it or the voltage across its terminals; this change in voltage or current is the first electrical signal.

[0043] A heat dissipation module is housed within the docking station and is primarily used to dissipate heat from the expansion dock, preventing overheating that could affect its performance or lifespan. Further, the heat dissipation module may include heat sinks, fans, and other heat dissipation components. The heat sinks accelerate heat dissipation by increasing the heat dissipation area, while the fans remove heat through airflow. This embodiment of the present disclosure does not impose specific limitations on these components. The heat dissipation module is electrically connected to the output terminal of the control module. It receives a second electrical signal from the control module and adjusts its operating state according to the magnitude of the second electrical signal, such as adjusting the opening angle of the heat sink or adjusting the fan speed.

[0044] The control module is also located inside the dock, and it includes a voltage detection unit, an input terminal, and an output terminal. The voltage detection unit is electrically connected to the input terminal, which in turn is electrically connected to the temperature detection module, so that the voltage detection unit can collect the first electrical signal from the temperature detection module. The output terminal is electrically connected to the heat dissipation module to output a second electrical signal to the heat dissipation module.

[0045] Furthermore, the voltage detection unit can be a voltage comparator that compares the first electrical signal from the input terminal with the electrical signal from the other input terminal to obtain the magnitude of the first electrical signal; or, the voltage detection unit can also be an analog-to-digital converter (ADC), an electronic component that can convert analog signals into digital signals. An input voltage signal, i.e., the first electrical signal, can be converted into a digital signal through an ADC.

[0046] When the voltage detection unit receives the first electrical signal, the control module determines the internal temperature of the expansion dock based on the magnitude of the first electrical signal. For example, if the heat dissipation effect of the heat dissipation module is positively correlated with the magnitude of the second electrical signal, then if the temperature corresponding to the first electrical signal is higher, the control module will output a relatively larger second electrical signal to the heat dissipation module; if the temperature corresponding to the first electrical signal is lower, the control module will output a relatively smaller second electrical signal. After receiving different magnitudes of the second electrical signal, the heat dissipation module can adjust its operating state according to the magnitude of the received second electrical signal. For example, if a larger second electrical signal is received, the heat dissipation module will increase its heat dissipation efforts (such as increasing fan speed, increasing heat sink power, or increasing the angle of the heat sink); if a smaller second electrical signal is received, the heat dissipation module will correspondingly reduce its heat dissipation intensity.

[0047] Furthermore, the control module can be a control chip, which can internally set multiple logic gate control signals or other necessary electronic components. This allows it to sample and compare the first electrical signal upon receipt, determine its magnitude, and output second electrical signals of different magnitudes through logic gates, thereby realizing the circuit's control function. Therefore, the embodiments of this disclosure are based on logic gate control according to the magnitude of the electrical signal, and do not involve computer program processing and judgment; the implementation of the circuit function depends on the hardware configuration.

[0048] In summary, this embodiment of the present disclosure, by incorporating a temperature detection module and a heat dissipation module within the docking station, allows the temperature detection module to detect temperature changes and send a first electrical signal to a control module. The control module then outputs a second electrical signal of varying magnitude to the heat dissipation module based on the magnitude of the first signal. The heat dissipation module operates differently under these varying second electrical signal values. Therefore, this embodiment of the present disclosure can dynamically adjust the heat dissipation of the docking station according to different temperature conditions within the station, thereby improving the heat dissipation effect, ensuring the normal operation of the docking station, and extending its service life.

[0049] It should be noted that the term "electrical connection" in this disclosure embodiment is also called "electrical link," which is a connection relationship used to illustrate this characteristic of the circuit when describing the circuit structure of a product. It can be understood as a form of connection between different components in the circuit structure through physical lines that can transmit electrical signals, such as PCB copper foil or wires. It is understood that the two electronic components in an "electrical connection" can be directly connected, or they can be indirectly connected by other electronic components in between.

[0050] In some embodiments, the heat dissipation module is a fan, which rotates at different speeds according to a second electrical signal with different duty cycles.

[0051] In this embodiment of the disclosure, a fan is set as a heat dissipation module. A fan is a common heat dissipation device that drives airflow by rotating blades. When the fan is working in the expansion dock, it will cause the surrounding air to circulate, so that the hot air inside the expansion dock is exhausted and the cold air is drawn in, thereby reducing the temperature of the expansion dock.

[0052] Duty cycle refers to the ratio of the duration of the high level to the total period time within one pulse cycle. In this embodiment of the present disclosure, the second electrical signal is a pulse signal whose duty cycle can vary between 0% and 100%.

[0053] It should be noted that when the second electrical signal output by the control module has a low duty cycle, it means that the high-level time is relatively short within a cycle. For the fan connected to this signal, the effective power received is relatively low, resulting in a lower average fan speed, smaller airflow, and weaker heat dissipation. This achieves a certain degree of heat dissipation while reducing fan noise and power consumption. Conversely, when the second electrical signal output by the control module has a high duty cycle, it means that the high-level time is longer within a cycle. The effective power received by the fan is higher, causing the fan speed to increase accordingly, generating a larger airflow. This allows for more effective heat dissipation from the expansion dock, suitable for situations where the internal temperature of the expansion dock is high and rapid heat dissipation is required.

[0054] Based on this, the control module in this embodiment dynamically adjusts the duty cycle of the second electrical signal according to the magnitude of the first electrical signal sent by the temperature detection module. When the internal temperature of the expansion dock is low, the first electrical signal is converted into a corresponding electrical signal by the voltage detection unit, and the control module generates a second electrical signal with a low duty cycle accordingly, causing the fan to run at a low speed. When the temperature rises, the first electrical signal changes accordingly, and the control module outputs a second electrical signal with a high duty cycle, causing the fan to run at a high speed, thus enhancing the heat dissipation effect. This method of adjusting the fan speed based on the duty cycle allows the expansion dock to achieve effective heat dissipation at different temperatures, avoiding the problems caused by the fan always running at high or low speeds, such as the high noise, high power consumption, and shortened fan life that may result from continuous high-speed operation, and the inability to meet heat dissipation requirements from continuous low-speed operation. At the same time, it can accurately adjust the heat dissipation intensity according to temperature changes, ensuring that the expansion dock maintains good heat dissipation performance under different working conditions and extending its service life.

[0055] The following describes the contents of the embodiments of this disclosure in conjunction with the circuit diagram:

[0056] Reference Figure 2 As shown, Figure 2This is a schematic diagram of an NTC sampling circuit provided in an embodiment of this disclosure. The NTC sampling circuit includes resistor R1 (10K, 10 kΩ), resistor R2 (1K), and NTC thermistor R3 (10K), as well as capacitor C1. Resistors R1 and R3 can be used to achieve voltage division, and capacitor C1 can be used for filtering and control. Resistor R1 and NTC thermistor R3 are connected in series, and the other end of resistor R1 is electrically connected to the power supply terminal of the control module. The power supply voltage is 3.3V. The other end of NTC thermistor R3 is grounded. AN0 is the input terminal of the control module, and the input terminal AN0 is connected to the connection point between resistor R1 and NTC thermistor R3 through resistor R2. Through this NTC sampling circuit, the control module can sample the voltage across NTC thermistor R3 via AN0, and the obtained voltage signal is the first electrical signal.

[0057] Reference Figure 3 As shown, Figure 3 This is a circuit diagram of the control module provided in the embodiment of this disclosure. The control module includes a control chip U1, which has 8 pins: VDD pin, PA6 / OSC2 / T1 G / CLKO pin, PC3 / P1C / PWM4 pin, PC2 / AN6 / P1 D / PWM5 pin, VSS pin, PA0 / AN0 / C1 I N+ / SCPCLK pin, PA1 / AN1 / C1 I N- / I SCPADAT pin, and PC4 / C2OUT / P1 B / PWM3 pin. Among them, the VDD pin, PA6 / OSC2 / T1 G / CLKO pin, PC3 / P1 C / PWM4 pin, and PC2 / AN6 / P1 D / PWM5 pin are electrically connected to the power supply of the control module, with a supply voltage of 3.3V. The PA6 / OSC2 / T1 G / CLKO pin, PC3 / P1 C / PWM4 pin, and PC2 / AN6 / P1 D / PWM5 pin are connected to the power supply through resistors R4 (10K), R5 (10K), and R6 (10K), respectively. Capacitor C2 (10uF) is electrically connected to the power supply, and its other end is grounded. The VSS pin is also grounded. The PA0 / AN0 / C1 IN+ / SCPCLK pin is the corresponding input pin and can be connected to AN0. The PA1 / AN1 / C1 IN- / I The SCPADAT pin is electrically connected to the power supply through resistor R7 (10K), which can form a comparison circuit with AN0 and connect to the voltage detection unit in the control chip U1. The PC4 / C2OUT / P1B / PWM3 pins are output terminals, which can output voltage signals with different duty cycles, that is, the second electrical signal.

[0058] Reference Figure 4 As shown, Figure 4 This is a schematic diagram of the fan control circuit provided in the embodiment of this disclosure. The fan control circuit includes a fan interface J2, which has 5 pins. Pin 1 is connected to the power supply BUS with a supply voltage of 5V. Pin 2 is connected to one end of the filter capacitor C3 (10uF) and ground. The other end of the capacitor C3 is connected to the power supply BUS. Pin 3 is connected to the output terminal of the control module. The output terminal is also connected to the power supply BUS through a resistor R8 (10K). A voltage divider resistor R9 (10R) is also provided between the output terminal and pin 3. Pins 4 and 5 are grounded respectively.

[0059] Based on the circuit described above, the fan speed unit in this embodiment can be set to four levels, and the corresponding second electrical signal can have four different output duty cycles. For example, when the first electrical signal is greater than 1.428V, the fan is in the first speed setting. In this case, the temperature inside the expansion dock is 0-30 degrees Celsius, the duty cycle of the corresponding second electrical signal is 0, and the fan speed is 0. When the first electrical signal is between 1.428V and 1.14V, the fan is in the second speed setting. In this case, the temperature inside the expansion dock is 31-40 degrees Celsius, the duty cycle of the corresponding second electrical signal is 35.16%, and the fan speed is 4436 rpm. When the first electrical signal is between 1.13V and 0.56V, the fan is in the third speed setting. In this case, the temperature inside the expansion dock is 41-50 degrees Celsius, the duty cycle of the corresponding second electrical signal is 60.19%, and the fan speed is 6660 rpm. When the first electrical signal is between 0.55V and 0.45V, the fan is in the fourth speed setting. In this case, the temperature inside the expansion dock is 51-60 degrees Celsius, the duty cycle of the corresponding second electrical signal is 99.67%, and the fan speed is 8632 rpm.

[0060] It should be noted that the fan speed in the above embodiments can be set according to actual needs, and the temperature inside the expansion dock can be measured based on the circuit example of the present disclosure embodiment. The present disclosure embodiment does not impose specific limitations on this.

[0061] In some embodiments, the temperature detection module includes a thermistor, and the control module further includes a power input terminal for electrical connection to an external power source.

[0062] One end of the thermistor is connected to the input terminal and is used for electrical connection with an external power supply, while the other end of the thermistor is grounded.

[0063] In this embodiment, a thermistor can be selected as part of the temperature detection module. A thermistor is a resistive element that is highly sensitive to temperature; its resistance changes significantly with temperature. Thermistors include two types: positive temperature coefficient (PTC) and negative temperature coefficient (NTC). In this embodiment, an NTC thermistor can be selected because its resistance decreases as temperature increases, allowing for convenient monitoring of temperature increases by measuring changes in resistance.

[0064] One end of the thermistor is connected to the input terminal of the control module and also to an external power supply. This means the external power supply provides a voltage to the thermistor, forming a simple voltage divider circuit. The other end of the thermistor is grounded, thus forming a complete circuit path. According to Ohm's law, when the resistance of the thermistor changes, the voltage across it also changes accordingly. This changing voltage is the first electrical signal sent to the input terminal of the control module. Then, based on the magnitude of the first electrical signal—that is, based on the temperature inside the expansion dock—the control module adjusts the duty cycle of the second electrical signal output to the cooling fan, thereby controlling the fan speed and ultimately achieving dynamic heat dissipation based on temperature.

[0065] In some embodiments, there are multiple temperature detection modules and multiple input terminals, and each input terminal is electrically connected to a corresponding temperature detection module.

[0066] In this embodiment, different locations may experience varying degrees of heat accumulation. For example, the expansion dock contains multiple heat sources, such as the main control chip, power conversion circuit, and different types of interfaces, each with varying degrees of heat generation and heat dissipation requirements. Therefore, this embodiment utilizes multiple temperature detection modules to monitor the temperature at these different locations, rather than relying solely on a single temperature sensor to reflect the overall temperature of the expansion dock.

[0067] Furthermore, in order to receive electrical signals from different temperature detection modules, the control module is equipped with multiple input terminals. Each input terminal is electrically connected to the corresponding temperature detection module, forming a one-to-one correspondence. This ensures that the electrical signals generated by each temperature detection module have a dedicated channel to be input into the control module, avoiding mutual interference or confusion of temperature signals from different locations.

[0068] Furthermore, the control module can comprehensively control the magnitude of the output second electrical signal based on the magnitudes of multiple different first electrical signals received, including outputting voltage signals with different duty cycles. For example, the control module can calculate the average value of the first electrical signals at multiple different locations and output a second electrical signal of corresponding magnitude based on the average value. This embodiment of the present disclosure does not impose specific limitations on this.

[0069] In some embodiments, there are multiple heat dissipation modules and multiple output terminals, and each output terminal is electrically connected to a corresponding heat dissipation module.

[0070] In this embodiment, since the expansion dock contains multiple heat sources and the heating conditions may vary depending on location and components, multiple heat dissipation modules can be used to provide targeted cooling for different areas. Furthermore, the control unit is equipped with multiple output terminals to achieve independent control of each heat dissipation module. Each output terminal has a unique function; it outputs a corresponding electrical signal based on the heat dissipation requirements of the connected heat dissipation module, thereby precisely controlling the operating state of different heat dissipation modules. For example, assuming the control unit receives a first electrical signal indicating a high temperature in a region from a temperature detection module near the control module, it can output a specific second electrical signal through the output terminal connected to the heat dissipation module in that region, thereby enhancing the heat dissipation effect of that heat dissipation module.

[0071] The following describes the contents of the embodiments of this disclosure in conjunction with the circuit diagram:

[0072] Reference Figure 5 As shown, Figure 5 This is another circuit diagram of the control module provided in this embodiment. The control module includes a control chip U2. To receive multiple first electrical signals, the control chip U2 can be configured with multiple input terminals, namely AN1, AN2, AN3, and AN4. The control chip U2 also has multiple output terminals, namely PWM1, PWM2, PWM3, and PWM4. Each input terminal can be connected to the aforementioned... Figure 2 The corresponding NTC sampling circuit is connected in the diagram. The diagram only shows AN1 connected to one NTC sampling circuit as an example. Similarly, each output terminal can also be connected to the above... Figure 4 The corresponding fan control circuit connection is shown in the figure. The figure only shows an example of PWM1 being connected to a fan control circuit.

[0073] Furthermore, the control chip U2 is model GD32F103C8T6. AN1, AN2, AN3 and AN4 correspond to pins PB12, PB13, PB14 and PB15 in the chip, and PWM1, PWM2, PWM3 and PWM4 correspond to pins PB3, PB4, PB5 and PB6 in the chip. The control chip U2 can connect each pin to the corresponding electronic components according to actual needs to realize the control function of the circuit. This embodiment does not impose specific limitations on this.

[0074] For example, in this embodiment of the present disclosure, multiple temperature detection modules and multiple heat dissipation modules can be simultaneously provided, such as four temperature detection modules (including four thermistors for temperature measurement) and four heat dissipation modules (four fans). The multiple temperature detection modules are located in the heat source area within the expansion dock, including near the control module, uplink port, downlink port (port for connection to the adapter), and data port, allowing for more accurate temperature detection of the heat-generating area. The heat dissipation modules are evenly distributed across the expansion dock. Further, the heat dissipation modules can be located near the control module, uplink port, downlink port (port for connection to the adapter), and data port, and additionally located in other areas with available space. When the control module receives first electrical signals from different locations, it can select the number of heat dissipation modules to control based on the average value of multiple first electrical signals, achieving comprehensive heat dissipation adjustment for the overall temperature within the expansion dock.

[0075] Furthermore, the control module can first control the heat dissipation modules located near the control module, uplink port, downlink port (port for connection to the adapter), and data port. When the average value is high, the remaining heat dissipation modules can then be controlled to operate, thereby achieving better heat dissipation. In addition to adjusting the operation of different heat dissipation modules, the rotational speed of each heat dissipation module can also be adjusted, which will not be elaborated in this embodiment.

[0076] Furthermore, the control module can also preferentially control the operation of the heat dissipation modules at corresponding locations based on the magnitude of the first electrical signal measured by temperature detection modules located near the control module, uplink port, downlink port (port for connection with the adapter), and data port. For example, if the first electrical signal from the temperature detection modules near the control module indicates that the temperature in that area is significantly higher than in other locations, the control module can control only the heat dissipation modules near the control module to operate, achieving targeted heat dissipation. Targeted heat dissipation at other locations is similar, and will not be elaborated upon in this embodiment.

[0077] In some embodiments, the expansion dock also includes a power detection module, and the dock body is provided with an uplink port and a data port. The uplink port is used for electrical connection with a terminal device, and the data port is used for electrical connection with an electronic device.

[0078] The power detection module is located inside the dock. The power detection device is electrically connected to the uplink port or data port and also electrically connected to the control module to transmit the power signal from the uplink port or data port to the control module. The control module is used to output a second electrical signal of different magnitude to the heat dissipation module through the output terminal according to the magnitude of the power signal.

[0079] In this embodiment, the uplink port is an interface used to electrically connect the docking station to a terminal device (such as a computer). It is the main channel for the docking station to receive data and power, and data and power can be transmitted from the terminal device to the docking station through this port. The data port is the interface used by the docking station to connect various electronic devices (such as external storage devices), and it is a key part of the docking station's extended functionality, enabling external electronic devices to communicate and transmit data with the terminal device.

[0080] The power detection module is housed within the docking station and is electrically connected to the uplink or data port, enabling it to acquire power information transmitted through these ports. For example, when an external electronic device connects to the docking station via the data port, the power detection module can sense the power it receives from the docking station; similarly, it can monitor when the docking station receives power from a terminal device via the uplink port. Furthermore, the power detection module converts the detected power information into an electrical power signal and transmits it to the control module. This signal reflects the magnitude of power transmitted through the uplink or data port.

[0081] The control module receives power signals from the power detection module and outputs secondary electrical signals of varying magnitudes to the heat dissipation module. For example, if the connected device is a high-power device (such as an external hard drive or high-resolution monitor), the power signal will be correspondingly larger, while when a low-power device (such as a mouse or keyboard) is connected, the power signal will be smaller. Based on the received power signal magnitude, the control module outputs secondary electrical signals of varying magnitudes to the heat dissipation module. Therefore, the docking station can dynamically adjust the operating state of the heat dissipation module according to actual power consumption, ensuring effective heat dissipation in different operating scenarios, avoiding overheating problems caused by power fluctuations, and guaranteeing the stable operation of the docking station and its connected devices.

[0082] In some embodiments, the expansion dock further includes multiple access detection modules disposed within the dock body, and the dock body is also provided with multiple data ports for electrical connection with electronic devices. Each access detection module is electrically connected to its corresponding data port, and the access detection module is also electrically connected to a control module to transmit the access electrical signal of the data port to the control module.

[0083] In this embodiment, an access detection module is placed inside the docking station to detect and manage the data ports of the expansion dock. Different data ports can support different types of electronic devices. The access detection module can detect the access status of the data ports. When an electronic device connects to or disconnects from a data port, it can sense these changes, convert the corresponding information into access electrical signals, and transmit the detected access electrical signals of the data ports to the control module.

[0084] After receiving the access electrical signal from the access detection module, the control module can perform corresponding processing based on these signals, such as starting the data transmission service, allocating the data transmission channel, adjusting the power distribution, and turning on the indicator lights corresponding to the port. This embodiment does not impose specific limitations on this.

[0085] In some embodiments, the docking station is provided with an uplink port and a data port. The uplink port is used for electrical connection with a terminal device, and the data port is used for electrical connection with an electronic device. The position of the temperature detection module corresponds to the position of the control module, the uplink port, or the data port.

[0086] In this embodiment, the placement of the temperature detection module is spatially matched with the control module, uplink port, or data port. That is, the temperature detection module can be placed close to the control module, uplink port, or data port. This is because the control module and these ports are key components for data transmission and power transmission in the docking station. During use, they generate heat when connecting external devices or communicating with terminal devices. Therefore, this embodiment can better detect the heat generation in different areas.

[0087] In some embodiments, the docking station is provided with an uplink port and a data port. The uplink port is used for electrical connection with a terminal device, and the data port is used for electrical connection with an electronic device. The position of the heat dissipation module corresponds to the position of the control module, the uplink port, or the data port.

[0088] In this embodiment, the placement of the heat dissipation module is spatially matched with the control module, uplink port, or data port. That is, the heat dissipation module can be placed close to the control module, uplink port, or data port because the control module and these ports are key components for data and power transmission in the docking station. During use, they generate heat when connecting external devices or communicating with terminal devices. The heat dissipation module is arranged near these ports to better dissipate heat from these heat-generating areas, thereby improving the heat dissipation effect.

[0089] In some embodiments, the dock body is provided with ventilation holes, the positions of which correspond to the positions of the heat dissipation module.

[0090] In this embodiment, the ventilation hole is an opening on the dock body, whose main function is to facilitate air exchange between the interior and exterior environments. When heat is generated inside the dock, it needs to be dissipated, and the ventilation hole provides a channel for this heat dissipation. Through airflow, hot air inside the dock is exhausted while cool air from the outside is introduced, helping to maintain temperature balance inside the dock and preventing heat buildup that could lead to decreased equipment performance and component damage.

[0091] For example, the ventilation holes can be located near the heat dissipation module within the dock, or they can be located on the opposite side of the heat dissipation module. For instance, if the heat dissipation module is located above the dock, the ventilation holes can be located below the dock, thereby improving the heat dissipation effect of the expansion dock.

[0092] It should also be understood that the various implementation methods provided in this disclosure can be combined arbitrarily to achieve different technical effects.

[0093] The above is a detailed description of the preferred embodiments of this disclosure. However, this disclosure is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this disclosure. All such equivalent modifications or substitutions are included within the scope defined by the claims of this disclosure.
