The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] like Figures 1-4 As shown in the embodiment of this utility model, a dual-axis linkage heat dissipation hinge structure for a laptop computer includes a housing 10, a connecting mechanism 20, a torque mechanism 30, and a heat dissipation mechanism 40. The torque mechanism 30 is disposed inside the housing 10, and one end of the connecting mechanism 20 is connected to the torque mechanism 30 and moves within the housing 10. The heat dissipation mechanism 40 is disposed on the torque mechanism 30 and the housing 10 and is used for heat dissipation of the laptop computer's internal and external parts. In this embodiment, the connecting mechanism 20 is connected to the torque mechanism 30 at one end and can move flexibly within the housing 10, making the opening and closing action of the laptop screen smooth and natural. It precisely controls the force and angle of the screen opening and closing, allowing users to easily adjust to a suitable viewing angle. At the same time, it ensures that the screen remains stable during use and does not shake randomly, greatly improving the user experience and avoiding stuttering or damage caused by poor connection. The heat dissipation mechanism 40 is set on the torque mechanism 30 and the housing 10, which helps to dissipate the heat generated by the computer in a timely manner, preventing the computer's performance from deteriorating due to overheating, extending the computer's service life, and ensuring that the computer can operate stably for a long time. It has a compact structure, good heat dissipation effect, and strong practicality.

[0029] like Figure 4 As shown, the housing 10 includes an upper shell 11 and a lower shell 12, which are fastened together to form a heat dissipation cavity 13. The connecting mechanism 20 and the torque mechanism 30 are disposed within the heat dissipation cavity 13. In this embodiment, the heat dissipation cavity 13 formed by the fastening of the upper shell 11 and the lower shell 12 provides a stable and protected installation space for the connecting mechanism 20 and the torque mechanism 30, preventing them from being affected by external environmental interference and physical damage. The heat dissipation cavity 13 can effectively guide airflow, carrying away the heat generated by the connecting mechanism 20 and the torque mechanism 30 during operation, preventing overheating from affecting the performance and lifespan of the components.

[0030] Mounting holes 14 are provided at both ends of the upper shell 11 and lower shell 12 near the heat dissipation cavity 13. Two sets of mounting holes 14 are arranged opposite each other. One end of the connecting mechanism 20 passes through the mounting hole 14 for connecting the computer screen and computer accessories. The torque mechanism 30 is used to open and close the mounting holes 14 for heat dissipation within the heat dissipation cavity 13. In this embodiment, the two sets of mounting holes 14 arranged opposite each other at both ends of the upper shell 11 and lower shell 12 near the heat dissipation cavity 13 provide a stable mounting position for the connecting mechanism 20, which can reliably connect the computer screen and computer accessories, ensuring the stability of the overall structure. The connecting mechanism 20 passes through the mounting holes 14 to ensure a tight connection between the two. The torque mechanism 30 allows the computer screen to open and close within the heat dissipation cavity 13 for heat dissipation. When the computer is running and generating heat, timely and reasonable opening and closing can achieve heat dissipation, effectively improving heat dissipation efficiency and extending the service life of the computer.

[0031] The upper shell 11 and lower shell 12 are provided with clearance grooves 15 on both sides near the heat dissipation cavity 13. Positioning pins 16 and positioning blocks 17 are provided within the clearance grooves 15 on both the upper shell 11 and lower shell 12 for positioning the torque mechanism 30 and connecting mechanism 20 during installation. In this embodiment, the clearance grooves 15 on both sides of the upper shell 11 and lower shell 12 near the heat dissipation cavity 13 provide installation space for the torque mechanism 30 and connecting mechanism 20, avoiding interference with other components and ensuring a reasonable layout of each mechanism. Furthermore, the positioning pins 16 and positioning blocks 17 within the clearance grooves 15 greatly improve the accuracy and stability of the installation.

[0032] The connecting mechanism 20 includes a first connecting hinge 21 and a second connecting hinge 22. The first connecting hinge 21 is provided with a first mounting element 211 for mounting the first connecting hinge 21 to a computer accessory. The second connecting hinge 22 is provided with a second mounting element 221 for mounting the second connecting hinge 22 to a computer accessory. In this embodiment, the first mounting element 211 on the first connecting hinge 21 and the second mounting element 221 on the second connecting hinge 22 ensure that both hinges can be securely mounted to the computer accessory, guaranteeing the reliability and stability of the connection and effectively ensuring the normal operation of the laptop's dual-axis linkage cooling hinge structure.

[0033] The torque mechanism 30 includes a first torque block 31, a second torque block 32, and a torque transmission rod 33. The first torque block 31 and the second torque block 32 are positioned opposite each other at both ends of the heat dissipation cavity 13 and are positioned by the positioning pin 16 and the positioning block 17. One end of the torque transmission rod 33 passes through the first torque block 31 and the second torque block 32. In this embodiment, by positioning the first torque block 31 and the second torque block 32 opposite each other at both ends of the heat dissipation cavity 13 and positioning them by the positioning pin 16 and the positioning block 17, the stability and accuracy of the structure are ensured. The positions of the two blocks can be accurately determined, enabling the entire torque mechanism 30 to operate reliably and allowing the dual-axis linkage of the heat dissipation shaft structure to be stably realized. This ensures that during the heat dissipation process of the laptop, the relevant components can work together as designed, improving heat dissipation efficiency, ensuring stable heat dissipation of the computer under various working conditions, and improving the overall performance and reliability of the computer.

[0034] The torque transmission rod 33 includes a first torque transmission rod 34 and a second torque transmission rod 35. The first torque transmission rod 34 has first torque sleeves 341 at both ends, and the two ends of the first connecting hinge 21 are respectively disposed on the first torque sleeves 341. The second torque transmission rod 35 has second torque sleeves 351 at both ends, and the two ends of the second connecting hinge 22 are respectively disposed on the second torque sleeves 351. In this embodiment, by having the first torque sleeves 341 at both ends of the first torque transmission rod 34 cooperate with the first connecting hinge 21, and the second torque sleeves 351 at both ends of the second torque transmission rod 35 cooperate with the second connecting hinge 22, the opening and closing action of the laptop screen can be made smoother and more stable; this enhances the stability of the structure and reduces the risk of loosening and damage caused by frequent opening and closing.

[0035] Torque limiting rings 36 and 37 are fitted onto the first torque transmitting rod 34 and the second torque transmitting rod 35, respectively. The torque limiting rings 36 and 37 are used to limit the movement of the first torque block 31 and the second torque block 32, allowing the first torque transmitting rod 34 and the second torque transmitting rod 35 to perform limiting movements on the first torque block 31 and the second torque block 32. In this embodiment, by limiting the movement of the first torque transmitting rod 34 and the second torque transmitting rod 35 in conjunction with the first torque block 31 and the second torque block 32, the hinge is ensured to rotate stably within a specified angle, preventing structural damage caused by excessive rotation. The limiting movement makes the dual-axis linkage more stable and accurate, ensuring that the heat dissipation components can adjust their position reasonably with the hinge movement during the opening and closing of the laptop, achieving efficient heat dissipation.

[0036] Both the first torque transmitter 34 and the second torque transmitter 35 are provided with heat dissipation channels 38. These channels 38 allow heat generated during the movement of the first torque transmitter 34 and the second torque transmitter 35 to be dissipated. In this embodiment, by providing heat dissipation channels 38 within the first torque transmitter 34 and the second torque transmitter 35, during laptop use, the dual-axis linkage causes the torque transmitter 33 to move continuously, generating a large amount of heat. The presence of the heat dissipation channels 38 provides an effective channel for heat dissipation, promptly releasing the heat generated by the movement of the torque transmitter 33, preventing heat accumulation inside the transmitter, and extending its service life.

[0037] The heat dissipation mechanism 40 includes multiple heat sinks 41, which are evenly distributed on the housing 10. Each heat sink 41 is a heat dissipation fin. In this embodiment, the multiple heat sinks 41 increase the heat dissipation area, enabling more efficient dissipation of heat generated inside the laptop, effectively reducing device temperature and ensuring stable operation. The heat dissipation fins improve heat dissipation efficiency; their unique shape and structure allow for better airflow between the fins, accelerating heat exchange and providing excellent heat dissipation.

[0038] A dual-axis linkage heat dissipation hinge structure for a laptop computer includes a housing 10, a connecting mechanism 20, a torque mechanism 30, and a heat dissipation mechanism 40. The torque mechanism 30 is disposed within the housing 10. One end of the connecting mechanism 20 is connected to the torque mechanism 30 and moves within the housing 10. The heat dissipation mechanism 40 is disposed on the torque mechanism 30 and the housing 10, and is used for heat dissipation of the laptop computer's internal and external components. In this embodiment, the connection between one end of the connecting mechanism 20 and the torque mechanism 30, allowing for flexible movement within the housing 10, enables smooth and natural screen opening and closing, precisely controlling the force and angle of screen opening and closing, allowing users to easily adjust to a suitable viewing angle. Simultaneously, it ensures the screen remains stable during use, preventing wobbling and greatly improving the user experience, avoiding stuttering or damage caused by poor connection. The heat dissipation mechanism 40, disposed on the torque mechanism 30 and the housing 10, helps to dissipate heat generated during computer operation in a timely manner, preventing performance degradation due to overheating, extending the computer's lifespan, and ensuring stable operation for extended periods. The structure is compact, has good heat dissipation performance, and is highly practical.
