Description

Technical Field

[0001] This utility model relates to the field of electronic accessories, and in particular to a magnetic expansion dock. Background Technology

[0002] In scenarios such as mobile office work and design creation, users' demands for data transfer, multi-monitor expansion, wired network connectivity, and storage capacity are increasing daily. Dock stations have thus become a key bridge connecting portability and powerful functionality. However, traditional docking stations are typically single-function, fixed in location, and have messy cables, failing to meet users' comprehensive needs for portable storage expansion, flexible desktop layout, and sustained high-performance device operation. Although existing docking station technology is mature, in mobility and high-load scenarios, the connection cables cannot be flexibly adjusted, not only occupying valuable desktop space but also causing significant inconvenience when moving due to cable length limitations, resulting in the docking station being very close to electronic devices. When working with external electronic devices, the electronic devices also generate heat. The simultaneous heat generation of both devices further exacerbates internal heat accumulation. Therefore, how to connect a docking station to electronic devices without being affected by the heat generated by the electronic devices or the docking station itself is an urgent problem to be solved. Utility Model Content

[0003] The main purpose of this invention is to propose a magnetic expansion dock, which aims to solve the problems of existing magnetic expansion docks being inconvenient to adjust and generating heat simultaneously with external electronic devices after connection.

[0004] To achieve the above objectives, this utility model proposes a magnetic expansion dock, which includes a housing, a fan and a storage circuit board disposed within the housing, and a magnetic component. The storage circuit board is provided with multiple data interfaces for connecting external devices, and at least part of the multiple data interfaces are exposed outside the housing; the magnetic component is disposed close to and parallel to the bottom shell of the housing for magnetically attracting external electronic devices; The magnetic component is an open or closed annular structure, and the end of the storage circuit board is provided with a clearance opening, which is located inside the annular structure. The fan is located at the clearance opening and is used to exhaust the heat from the annular structure through the first vent on the side of the box in a direction perpendicular to the bottom shell during operation.

[0005] Optionally, the magnetic component includes a magnet and a magnet support, the magnet support being connected to the bottom shell, and the magnet being disposed on one side of the magnet support facing the bottom shell, forming the annular structure of the magnet between the magnet support and the bottom shell.

[0006] Optionally, the fan includes fan blades and a heat dissipation bracket, the heat dissipation bracket is disposed on the magnet bracket, and the fan blades are disposed inside the heat dissipation bracket; the side of the heat dissipation bracket facing the magnet bracket is provided with a first air inlet, and the fan blades disposed inside the heat dissipation bracket draw in the heat emitted from the annular structure through the first air inlet.

[0007] Optionally, the box body includes a middle frame, the side wall of the middle frame is provided with the first ventilation opening, the heat dissipation bracket is also provided with an air outlet, the air outlet is provided corresponding to the first ventilation opening, so that the air outlet is discharged in a direction perpendicular to the bottom shell or the annular structure.

[0008] Optionally, the heat dissipation bracket is further provided with a second air inlet, which is parallel to the first air inlet and perpendicular to the orientation of the air outlet. The second air inlet is used to draw in heat from the box or the storage circuit board.

[0009] Optionally, the magnet includes a first magnetic attraction portion and a second magnetic attraction portion disposed opposite to each other, and the first magnetic attraction portion and the second magnetic attraction portion are spaced apart to form an annular structure with an opening, the first magnetic attraction portion and the second magnetic attraction portion being used to magnetically connect with an external electronic device at the annular structure.

[0010] Optionally, the magnet bracket is provided with a first mounting groove and a second mounting groove, and both the first mounting groove and the second mounting groove are disposed towards the bottom shell. The first magnetic attraction part and the second magnetic attraction part are respectively disposed in the first mounting groove and the second mounting groove, and the height of the first magnetic attraction part and the second magnetic attraction part does not exceed the height of the first mounting groove and the second mounting groove.

[0011] Optionally, the heat dissipation bracket includes an upper bracket and a lower bracket. The upper bracket is disposed on the lower bracket in a direction opposite to the magnet bracket, and the lower bracket is connected to the magnet bracket. The lower bracket has a protrusion, and the upper bracket has a connecting hole. The upper bracket and the lower bracket are connected to the protrusion through the connecting hole to form a fastening connection.

[0012] Optionally, the housing further includes an LED screen bracket, which is located inside the middle frame in conjunction with the middle frame, and a second ventilation opening is provided on one side of the LED screen bracket, corresponding to the position of the first ventilation opening.

[0013] Optionally, the magnetic docking station further includes a fingerprint component, which is partially exposed on the surface of the housing to receive fingerprint information. The fingerprint component is electrically connected to the storage circuit board to unlock the storage circuit board.

[0014] This utility model's technical solution involves placing a fan at a clearance opening on the storage circuit board, allowing the fan to directly dissipate heat from the circuit board. Simultaneously, a magnetic component is incorporated into the housing, forming a ring structure. The clearance opening is correspondingly positioned within this ring structure, placing the fan within the same ring. During use, the ring structure quickly attaches to the electronic device. Since both the magnetic docking station and the electronic device generate heat during operation, heat accumulation occurs within the ring structure after their magnetic connection. By placing the fan within the corresponding position of the ring structure formed by the magnetic component, heat dissipation is achieved at the ring structure where the magnetic docking station and electronic device are magnetically connected. The hot air is then blown out of the housing through a first ventilation opening on the side, preventing the hot air from passing through the bottom shell or the ring structure, thus avoiding exacerbating heat accumulation within the ring structure. This achieves not only heat dissipation for the magnetic docking station but also prevents the heat from the electronic device and the magnetic docking station from interacting and causing a simultaneous increase in device temperature.

[0021] Currently, the mainstream docking stations on the market mainly use a circuit board that integrates multiple interfaces, encapsulated in a plastic or metal shell, and connect to a laptop or other electronic device via a fixed or pluggable data cable. There are no other fixed structures, which means that when moving electronic devices, it is necessary to carry the docking station and the electronic device together, which is very inconvenient in mobility and high-load scenarios. Furthermore, existing docking stations typically lack active cooling structures. For high-performance docking stations or those with integrated SSDs, passive cooling methods are usually employed, such as heat dissipation through a metal casing (commonly aluminum alloy) or by adding ventilation holes to the casing. However, during high-load tasks such as high-speed data transfer (e.g., reading and writing to the built-in SSD) and video output, the internal chips and SSD generate significant heat. Purely passive cooling methods are inefficient and can easily lead to heat buildup inside the docking station, causing the SSD or controller chip to throttle due to overheating. This can result in a significant drop in transmission speed, affecting work efficiency and device lifespan. This heat buildup is exacerbated when the docking station is connected to electronic devices, as the electronic devices also generate heat. The simultaneous heat generation of both devices not only affects heat dissipation but also intensifies the accumulation of heat within both devices, leading to device failure or damage.

[0022] To address the aforementioned problems, this utility model proposes a magnetic docking station 100, with reference to... Figure 1 A fan 20 is installed at the clearance 32 on one side of the storage circuit board 30, so that the fan 20 can directly dissipate heat from the storage circuit board 30, while also ensuring that the space inside the box 10 is fully utilized, resulting in a smaller overall size. When it is working, the fan 20 can dissipate heat from the inside of the box 10. Furthermore, by installing a magnetic component 40 on the box 10, it can quickly connect to and fix electronic devices (such as tablets, mobile phones, etc.). When moving electronic devices, the magnetic docking station 100 can be moved simultaneously, which is convenient for movement. Compared with the previous connection by data cable alone, it has a better fixing effect and reduces the risk of devices or cables falling off during movement. Since the magnetic docking station 100 dissipates heat to the outside, and the electronic equipment also dissipates heat, heat accumulation occurs when they are connected, further aggravating the temperature of both devices and causing damage. This solution uses a fan 20 positioned at the annular structure formed by the magnetic component 40. When the fan is running, it not only dissipates heat from inside the housing 10 but also from the annular structure. Therefore, it is particularly beneficial for heat dissipation at the connection point between the electronic equipment and the magnetic docking station 100, preventing heat accumulation. This utility model has the following embodiments: Example

[0023] This embodiment provides a connection method. (See reference...) Figure 1 The housing 10 consists of a bottom shell 11, a middle frame 12, and a front shell 13. The fan 20 and the storage circuit board 30 are both located inside the housing 10. The middle frame 12 has first ventilation openings 121 on both side walls, perpendicular to the bottom shell 11. These openings connect the inside and outside of the housing 10, allowing for air convection. The storage circuit board 30 connects to multiple data interfaces 31, such as USB-A, HDMI, DP, SD card reader, and network cable interface. These multiple data interfaces 31 are located within the housing. The side wall of 10 is used to connect external electronic devices. The storage circuit board 30 is used to realize the storage function after being connected to the electronic device. Since the storage circuit board 30 integrates many electronic circuit components, there is a clearance opening 32 on one side of the storage circuit board 30. The clearance opening 32 matches the shape of the fan 20. The fan 20 is located at the clearance opening 32. When the electronic circuit components heat up, the fan 20 can directly dissipate heat. At the same time, the setting of the clearance opening 32 also makes full use of the space inside the box 10, without increasing the thickness of the storage circuit board 30, thus miniaturizing the device. Specifically, the magnetic component 40 includes a magnet 41 and a magnet support 42. The magnet 41 has a ring-shaped structure, and the clearance opening 32 is located in the corresponding area of ​​the ring-shaped structure so that the fan 20 is also within the ring-shaped structure. When the fan 20 dissipates heat, the heat from the ring-shaped structure or the magnet 41 is dissipated simultaneously, thereby enhancing the heat dissipation capacity of the magnetic docking station 100. Furthermore, the magnet support 42 is arranged parallel to the bottom shell 11 of the housing 10, and the magnet 41 is located on the side of the magnet support 42 facing the bottom shell 11, and the magnet 41 is positioned near the fan. The bottom shell 11 of the fan 20 and the heat dissipation bracket 22 facing the magnet bracket 42 are provided with a first air inlet 221. The first air inlet 221 can exhaust the heat near the magnet 41 through the fan blades 21 and the first ventilation port 121 outside the box 10. The first ventilation port 121 is located on the side of the middle frame 12. When the fan 20 dissipates heat, it blows the hot air to the side of the box 10, so that the hot air will not pass through the bottom shell 11, the magnet 41 and the ring structure, thereby achieving heat dissipation without aggravating the temperature of itself and external electronic devices after connection. Preferably, the direction of hot air exhaust is perpendicular to the bottom shell 11, the magnet 41, and the annular structure, so as not to affect the temperature of the annular structure set in the bottom shell 11. After connecting the electronic device, the entire bottom shell 11 may be in close contact with the electronic device, and the side wall where the first vent 121 is located is perpendicular to the bottom shell 11. Therefore, the hot air is exhausted in the direction perpendicular to the bottom shell 11. This heat dissipation method prevents the entire bottom shell 11 from generating heat accumulation with the electronic device and improves the heat dissipation effect. refer to Figure 3 and Figure 4 The fan blades 21 of the fan 20 are located inside the heat dissipation bracket 22, which is fixed to the magnet bracket 42. The heat dissipation bracket 22 also has a second air inlet 223 facing the face shell 13, which can promote airflow inside the box 10; it also has an air outlet 222 facing a first ventilation port 121, which can create airflow inside the box 10 and dissipate heat to the external environment. This arrangement makes the heat dissipation path of the fan 21 first absorb heat from the storage circuit board 30 or the box 10, and then blow it through the air outlet 222 to the first ventilation port 121 of the middle frame 12, and blow it out of the box 10 from the side wall of the box 10. In particular, it can alleviate the heat accumulation generated at the ring structure and the connected electronic devices. Compared with the existing design, it will not aggravate the temperature at the ring structure and the connected electronic devices. Among them, reference Figure 2The magnet 41 includes a first magnetic attraction part 411 and a second magnetic attraction part 412 arranged opposite to each other. Both the first magnetic attraction part 411 and the second magnetic attraction part 412 are semi-circular arcs and are spaced apart to form a ring structure, which makes the magnetic attraction range large and the magnetic attraction stable. The first magnetic attraction part 411 and the second magnetic attraction part 412 are used to magnetically connect with external electronic devices to form a connection point. Correspondingly, the magnet bracket 42 is provided with a first mounting groove 421 and a second mounting groove 422, and both the first mounting groove 421 and the second mounting groove 422 are arranged facing the bottom shell 11. The first magnetic attraction part 411 and the second magnetic attraction part 412 are respectively provided in the first mounting groove 421 and the second mounting groove 422. Preferably, the height of the first magnetic attraction part 411 and the second magnetic attraction part does not exceed the depth of the first mounting groove 421 and the second mounting groove 422, so that the thickness of the magnet bracket 42 is thin. The magnetic expansion dock 100 can realize the miniaturization of the device size, which meets the current market demand for devices. Preferably, the housing 10 further includes an LED screen bracket 14, as shown in the reference. Figure 5 , Figure 5 To conceal the structural diagram of the faceplate 13, the LED screen bracket 14 is used to place the LED display screen 70. The faceplate 13 is made of glass and can display information such as storage capacity and power to the user. The LED screen bracket 14 is located inside the middle frame 12 in conjunction with the middle frame 12. The LED screen bracket 14 has a second ventilation opening 141 corresponding to the position of a first ventilation opening 121, which is used to cooperate with the fan 20 to dissipate heat and exhaust the air inside the box 10 to the outside, so that air can also circulate between the faceplate 13 and the LED screen bracket 14, thereby enhancing the overall heat dissipation performance. The LED screen bracket 14 is also provided with a connecting hole 142, which can allow the LED display screen 70 to be electrically connected to the storage circuit board 30. The magnetic expansion dock 100 can be activated by the button 15 provided on the side wall of the middle frame 12. The user can view the storage status and information through the LED display screen 70. Preferably, decorative parts can also be provided on the LED screen bracket 14 to enhance the overall aesthetics of the magnetic expansion dock 100. To improve the stability of the fan 20, the heat dissipation bracket 22 is provided with an upper bracket 224 and a lower bracket 225. The upper bracket 224 is located on the lower bracket 225 in the direction away from the magnet bracket 42. The lower bracket 225 is connected to the magnet bracket 42. The lower bracket 225 is provided with a protrusion 2251. The upper bracket 224 is provided with a connecting hole 2241. The upper bracket 224 and the lower bracket 225 are connected to the protrusion 2251 through the connecting hole 2241 to form a fastening connection. The fan blade is fixedly installed on the lower bracket 225 to keep it stable during operation.

[0024] Based on the foregoing embodiments, in one embodiment, the magnetic docking station 100 further includes a fingerprint component 50. The fingerprint component 50 is equipped with a fingerprint key capable of recognizing fingerprint information and a fingerprint motherboard for reading and matching fingerprint information. The front shell 13 of the housing 10 has a mounting hole 131, and the fingerprint key is located in the mounting hole 131 for the user to trigger fingerprint recognition. (Reference) Figure 6 The fingerprint key is exposed on the faceplate 13 and can be used directly. The fingerprint motherboard is electrically connected to the storage circuit board 30. When the user presses the fingerprint key, the fingerprint key acquires the user's fingerprint and identifies and matches it through the fingerprint motherboard. When the fingerprint information matches the pre-stored information, the storage circuit board 30 can be unlocked for use, which greatly increases the security and privacy of the magnetic docking station 100.
