Description
Technical Field
[0001] This disclosure relates to the field of hinge technology, and more particularly to a hinge structure and electronic device. Background Technology
[0002] Currently, the space for the rear air vents on laptops is limited by the hinge cover, thus restricting the laptop's heat dissipation capacity and hindering the improvement of central processing unit (CPU) performance. Existing solutions include: one is to make the keyboard openable, raising the keyboard to create an angle between it and the bottom panel (D-frame) to provide cooling space; however, this solution has drawbacks such as limited cooling effect, causing hot air recirculation, and making it easy for foreign objects to enter the laptop, causing structural damage, preventing it from closing properly, and easily scratching the screen. Another solution is to lengthen and raise the air vents to achieve a cooling effect; however, this sacrifices the laptop's slim and light characteristics, making it bulkier. Summary of the Invention
[0003] This disclosure provides a hinge structure and an electronic device to at least solve one of the technical problems existing in the prior art.
[0004] In a first aspect, this application provides a hinge structure applied to an electronic device, the electronic device including a first housing and a second housing, the hinge structure comprising: The pivot shaft is pivotally connected at its first end to the first housing component; A first gear is mounted on the second end of the rotating shaft; The second gear meshes with the first gear; A first connecting rod, the first end of which is pivotally connected to the second gear, with the pivot position offset from the axis of the second gear; the second end of the first connecting rod is pivotally connected to the second housing; when the first housing rotates relative to the second housing, it drives the rotating shaft and the first gear to rotate, causing the second gear to rotate under the meshing transmission of the first gear, which in turn drives the first end of the first connecting rod to move away from or towards the rotating shaft, so that when the first housing rotates relative to the second housing, the connecting axis between the first housing and the rotating shaft moves towards or away from the second housing.
[0005] In one embodiment, the hinge structure further includes a sliding member, the first end of which is sleeved on the second end of the rotating shaft, and the sliding member is located on the side of the first gear facing the first end of the rotating shaft. The sliding member also has a mounting portion near its first end, and the second gear is pivotally connected to the mounting portion at its axial position. When the connecting axis between the first housing and the rotating shaft moves toward or away from the second housing, it drives the first end of the sliding member to move toward or away from the second housing.
[0006] In one embodiment, the hinge structure further includes a fixing member, which is fixedly connected to the second housing, and the second end of the sliding member is slidably connected to the fixing member; when the connecting axis between the first housing and the rotating shaft moves toward or away from the second housing, it drives the second end of the sliding member to slide back and forth on the fixing member; The second end of the first connecting rod is pivotally connected to the fixing member.
[0007] In one embodiment, the fixing member has a sliding hole, and the second end of the sliding member is slidably connected to the sliding hole.
[0008] In one possible implementation, with the first plane where the second housing is located as a reference, the fixing member is fixed to the second housing in such a way that the second plane where its sliding hole is located is parallel to the first plane; Alternatively, the fastener is fixed to the second housing in such a way that the second plane containing its sliding hole forms an acute angle with the first plane.
[0009] In one embodiment, the hinge structure further includes a second link, which is disposed on the side of the first gear and the second gear facing away from the first end of the rotating shaft, and the first end of the second link is sleeved on the second end of the rotating shaft, and the second end of the second link is sleeved on the mounting portion of the sliding member.
[0010] In one possible embodiment, the pivot position of the first connecting rod and the second gear is located away from the pivot position of the second gear and the mounting portion.
[0011] In one embodiment, the rotating shaft is provided with a protrusion, and a sleeve fitted onto the rotating shaft is provided between the protrusion and the first end of the sliding member; the sleeve is used to adjust the distance between the first gear and the first end of the rotating shaft.
[0012] In one embodiment, the hinge structure further includes a torque component connected to the first end of the rotating shaft. The torque component is configured to generate a stable circumferential damping torque when the first shell rotates relative to the second shell, so that the first shell remains stationary at any rotation angle. The mounting bracket is located between the torque assembly and the protrusion, with its first end sleeved on the rotating shaft and its second end fixedly connected to the first housing.
[0013] Secondly, this application provides an electronic device, including a first housing and a second housing. The first side of the second housing has a heat dissipation vent, and the device also includes a hinge structure as described in any of the above-described embodiments. The first side of the second housing is movably connected to the first housing via the hinge structure. When the first housing rotates relative to the second housing, it drives the rotating shaft and the first gear to rotate. When the second gear rotates under the meshing transmission of the first gear, it drives the first end of the first connecting rod to move away from or towards the rotating shaft. This achieves that when the first housing rotates relative to the second housing, the connecting axis between the first housing and the rotating shaft moves towards or away from the heat dissipation vent of the second housing.
[0014] Compared with the prior art, the advantages of this application are as follows: 1) This application provides a hinge structure that, when the first shell is opened or closed relative to the second shell, can synchronously drive the rotating shaft to rotate counterclockwise or clockwise, thereby increasing or decreasing the distance between the connecting axis of the first shell and the rotating shaft and the second shell. Thus, the distance between the first shell and the second shell increases with the increase of the rotation angle of the first shell, achieving the function of the first shell retracting relative to the second shell while increasing the space of the heat dissipation vent, thus improving the heat dissipation capacity of the laptop. 2) In this application, when the fixing member is fixed parallel to the second shell, the first shell can be opened by rotation and can also be translated away from the second shell through the hinge structure. Alternatively, when the fixing member is fixed to the second shell at an acute angle, the first shell can be opened by rotation and can also be moved obliquely away from the second shell through the hinge structure, further increasing the space at the heat dissipation vent and improving the heat dissipation efficiency of the laptop.

Detailed Implementation
[0019] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.
[0020] Firstly, such as Figure 1 , Figure 11 As shown, this application provides a hinge structure 1 applied to an electronic device 2. The electronic device 2 includes a first housing 21 and a second housing 22. The hinge structure 1 includes: The first end of the rotating shaft 11 is pivotally connected to the first housing 21; The first gear 12 is mounted on the second end of the rotating shaft 11; The second gear 13 meshes with the first gear 12. The first link 14 has its first end pivotally connected to the second gear 13, and the pivotal position of the two is offset from the axis of the second gear 13; the second end of the first link 14 is pivotally connected to the second housing 22. When the first housing 21 rotates relative to the second housing 22, it drives the rotating shaft 11 and the first gear 12 to rotate. When the second gear 13 rotates under the meshing transmission of the first gear, it drives the first end of the first connecting rod 14 to move away from or towards the rotating shaft 11. This achieves the following: when the first housing 21 rotates relative to the second housing 22, the connecting axis between the first housing 21 and the rotating shaft 11 moves towards or away from the second housing 22.
[0021] For example, in this application, the first end of the rotating shaft 11 is pivotally connected to the first housing 21, so that the first housing 21 can rotate relative to the axis of the rotating shaft 11.
[0022] For example, in this application, the connecting axis between the first housing 21 and the rotating shaft 11 is the axis of rotation of the rotating shaft 11.
[0023] For example, such as Figure 8-11 As shown, the hinge structure 1 of this application is applied to an electronic device 2, which includes, but is not limited to, a laptop computer. The laptop computer includes a first shell 21 (e.g., the B-piece of the laptop computer (i.e., the screen frame)) and a second shell 22 (the C-piece of the laptop computer (i.e., the shell where the laptop computer's keyboard is located)). Taking laptops as an example, in current technologies, the axis of the hinge of a laptop is fixed relative to the first and second shells, and their distance is usually constant. The second shell, located at the hinge position, has a heat dissipation vent on its first side (i.e., a heat dissipation vent at the rear of the laptop) for cooling during operation. However, the space for this vent is blocked and restricted by the hinge cover on the hinge. Since the distance between the connecting axis of the first shell and the hinge and the second shell remains constant with the opening angle of the first shell, the heat generated inside the laptop increases over time and cannot be effectively dissipated through the heat dissipation vent, resulting in limited cooling capacity and an inability to improve CPU (Central Processing Unit) performance. Therefore, in order to improve the heat dissipation capacity of a laptop, this application provides a hinge structure 1. The pivot 11 of the hinge structure 1 is pivotally connected to a first housing (e.g., the B part of a laptop). When the first housing 21 is opened relative to the second housing 22 (the C part of a laptop), it can synchronously drive the pivot 11 to rotate counterclockwise. While the pivot 11 rotates counterclockwise, it synchronously drives the first gear 12 to rotate. Since the first gear 12 and the second gear 13 are meshed, when the first gear 12 rotates, it drives the second gear 13 to synchronously drive the first connecting rod 14 to rotate. Because the first end of the first connecting rod 14 is pivotally connected to the second gear 13 and the pivot position of the two is offset from the axis of the second gear (i.e., the first connecting rod 14 and the second gear 13 are substantially eccentrically connected), this offset... The pivot connection allows the distance between the first end of the first connecting rod 14 and the rotating shaft 11 to increase as the rotation angle of the first housing increases when the second gear 13 drives the first end of the first connecting rod 14 to rotate. Consequently, the distance between the connecting axis of the first housing 21 and the rotating shaft 11 and the first end of the first connecting rod 14 gradually increases as the rotation angle of the first housing 21 increases. Furthermore, since the second end of the first connecting rod 14 is pivotally connected to the second housing 22, the second end of the first housing 14 is always restricted to the second housing. Thus, while the first housing 21 rotates relative to the second housing 22, the connecting axis of the first housing 21 and the rotating shaft 11 also moves away from the second housing 22, increasing the space of the heat dissipation vent on the first side of the second housing 22 and improving the heat dissipation capacity of the laptop.In summary, the distance between the connecting axis of the first shell 21 and the hinge 11 and the second shell 22 increases with the rotation angle of the first shell 21. This allows the first shell 21 to rotate relative to the second shell 22 to open the laptop while simultaneously moving away from the second shell 22, thereby increasing the space for the heat dissipation vent at the rear of the laptop and improving its heat dissipation capacity. Similarly, when the laptop is closed, i.e., the rotation angle of the first shell 21 relative to the second shell 22 gradually decreases, the connecting axis of the first shell 21 and the hinge 11 also moves closer to the second shell 22, reducing the space for the heat dissipation vent on the first side of the second shell 22 until the laptop is completely closed. Therefore, by employing the hinge structure 1 of this application, the laptop achieves the following: when the first shell 21 rotates relative to the second shell 22 (including opening or closing), the connecting axis of the first shell 21 and the hinge 11 moves closer to or further away from the second shell 22, thereby adjusting the space for the heat dissipation vent at the rear of the laptop and improving its heat dissipation capacity.
[0024] This application improves upon the existing laptop hinge, maintaining its rotational function while adding a sliding function. When the laptop is closed, as... Figure 10 As shown, the angle between the first shell 21 and the second shell 22 is 0 degrees, the same as that of a normal laptop computer, so it will not protrude from the screen and does not increase the thickness. Figure 11 As shown, when the first housing 21 is opened by rotating counterclockwise, it drives the rotating shaft 11 to rotate synchronously, thereby increasing the distance between the first end of the first connecting rod 14 and the rotating shaft 11, causing the first housing 21 to move backward relative to the second housing 22, increasing the space at the heat dissipation outlet, thereby increasing the heat dissipation efficiency and reducing heat recirculation.
[0025] In one possible implementation, such as Figure 2 , Figure 6 As shown, the hinge structure 1 of this application also includes a sliding member 17. The first end of the sliding member 17 is sleeved on the second end of the rotating shaft 11, and the sliding member 17 is disposed on the side of the first gear 12 facing the first end of the rotating shaft 11. The sliding member 17 also has a mounting part 171 near its first end. The second gear 13 is pivotally connected to the mounting part 171 at its axial position. When the connecting axis of the first housing 21 and the rotating shaft 11 moves toward or away from the second housing 22, it drives the first end of the sliding member 17 to move toward or away from the second housing 22.
[0026] When the first housing 21 synchronously drives the rotating shaft 11 to rotate, the sliding member 17 does not rotate with the rotating shaft 11. The sliding member 17 is rotatably connected to the axial position of the second gear 13 through the mounting part 171. The sliding member 17 provides the conditions for the installation of the second gear 13. When the first gear drives the second gear to rotate, the second gear 13 rotates around the mounting part 171 and simultaneously drives the first end of the first connecting rod 14 to move away from or towards the rotating shaft 11, thereby increasing or decreasing the distance between the first end of the first connecting rod 14 and the rotating shaft 11.
[0027] For example, the pivot position of the first connecting rod 14 and the second gear 13 is set away from the pivot position of the second gear 13 and the mounting part 171.
[0028] Because the pivot position of the first connecting rod 14 and the second gear 13 is offset from the axis of the second gear 13, the first end of the first connecting rod 14 and the second gear 13 are essentially eccentrically connected. Therefore, when it is necessary to further increase the distance between the rotating shaft 11 and the second housing 22, this eccentrically connected position can be moved away from the pivot position between the second gear 13 and the mounting part 171. In other words, by appropriately increasing the diameter of the second gear 13, the distance between the rotating shaft 11 and the second housing 22 can be increased, thereby increasing the space for the heat dissipation vent and improving heat dissipation efficiency.
[0029] In one possible implementation, such as Figure 3-5 , Figure 8 As shown, the hinge structure 1 of this application also includes a fixing member 18, which is fixedly connected to the second shell 22, and the second end of the sliding member 17 is slidably connected to the fixing member 18; when the connecting axis of the first shell 21 and the rotating shaft 11 moves toward or away from the second shell 22, it drives the second end of the sliding member 17 to slide back and forth on the fixing member 18. The second end of the first connecting rod 14 is pivotally connected to the fixing member 18. The second end of the first connecting rod 14 is indirectly pivotally connected to the second housing member 22 through the fixing member 18.
[0030] like Figure 5-6 As shown, the first gear 12 is sleeved and installed on the second end of the rotating shaft 11, and can rotate synchronously with the rotating shaft 11. The axial position of the second gear 13 is rotatably installed on the mounting part 171 of the sliding member 17. The first gear 12 and the second gear 13 mesh, so that when the first gear 12 rotates, it can drive the second gear 13 to rotate synchronously. The rotatable connection position between the mounting part 171 of the sliding member 17 and the second gear 13 is the axial position of the second gear 13. Since the second gear 13 is eccentrically rotatably connected to the first end of the first connecting rod 14, when the angle between the first housing 21 and the second housing 22 is 0 degrees, as... Figure 4As shown, the distance between the first end of the first connecting rod 14 and the rotating shaft 11 is the smallest, and the distance between the axis of the first gear 13 and the pivot position of the fixing member 18 and the second end of the first connecting rod 14 is the smallest. As the first housing 21 rotates counterclockwise to open, the included angle between it and the second housing 22 gradually increases, as... Figure 5 As shown, the first gear 12 drives the second gear 13 to rotate, causing the second gear 13 to synchronously drive the first end of the first connecting rod 14 to rotate away from the rotating shaft 11. The distance between the first end of the first connecting rod 14 and the axis of the rotating shaft 11 gradually increases. Since the connection position between the second end of the first connecting rod 14 and the fixing member 18 remains unchanged, the distance between the axis of the first gear 12 and the pivot position of the fixing member 18 and the second end of the first connecting rod 14 gradually increases. The rotating shaft 11 drives the first housing 21 to move away from the fixing member 18, and the distance between it and the fixing member 18 gradually increases. The second end of the sliding member 17 also slides away from the fixing member 18 on the fixing member. As a result, the distance between the entire connecting axis of the first housing 21 and the rotating shaft 11 and the second housing 22 is extended, thereby increasing the space at the heat dissipation vent of the laptop and improving the heat dissipation efficiency of the laptop.
[0031] Furthermore, the fixing member 18 has a sliding hole 181, and the second end of the sliding member 17 is slidably connected to the sliding hole 181.
[0032] For example, such as Figure 5-6 As shown, the fixing member 18 has a sliding hole 181, and the direction of the sliding hole 181 is perpendicular to the direction of the rotating shaft 11. The second end of the sliding member 17 is slidably connected to the sliding hole 181. When the angle between the first shell member 21 and the second shell member 22 is 0 degrees, as shown... Figure 1 As shown, the second end of the slider 17 is inserted into the sliding hole 181. When the first housing 21 is rotated counterclockwise, as... Figure 5 As shown, the first housing 21 drives the rotating shaft 11 to rotate counterclockwise and also drives the rotating shaft 11 to move away from the second housing 22. The rotating shaft 11 then drives the second end of the sliding member 17 to slide away from the sliding hole 181 in the sliding hole 181. The sliding hole 181 of the fixing member 18 guides the sliding of the sliding member 17 and makes the first housing 21 smoothly drive the rotating shaft 11 to move away from the second housing 22.
[0033] For example, such as Figure 12 As shown, with the first plane where the second shell 22 is located as a reference, the fixing member 18 is fixed to the second shell 22 in such a way that the second plane where its sliding hole is located is parallel to the first plane; Or, such as Figure 13 As shown, the fastener 18 is fixed to the second housing 22 in such a way that the second plane where the sliding hole is located forms an acute angle with the first plane.
[0034] Taking a laptop computer as an example, the second shell 22 is component C of the laptop, and the first shell 21 is component B. When the fixing member 18 is fixed parallel to the second shell 22, the first shell 21 can be rotated and opened, and can also be translated away from the second shell 22 via the hinge structure 1 (e.g., ...). Figure 12 (In the direction indicated by the arrow). When the fixing member 18 is fixed to the second shell 22 at an acute angle, it allows the first shell 21 to rotate and open, while also enabling it to move obliquely away from the second shell 22 via the hinge structure 1 (e.g., Figure 13 (As shown by the arrow), the oblique movement direction is parallel to the second plane where the sliding hole 181 is located, further increasing the space at the heat dissipation vent and improving the heat dissipation efficiency of the laptop.
[0035] Furthermore, such as Figure 5 As shown, the hinge structure 1 of this application also includes a second link 19. The second link 19 is disposed on the side of the first gear 12 and the second gear 13 facing away from the first end of the rotating shaft 11, and the first end of the second link 19 is sleeved on the second end of the rotating shaft 11, and the second end of the second link 19 is sleeved on the mounting part 171 of the sliding member 17.
[0036] The two ends of the second connecting rod 19 are respectively connected to the second end of the rotating shaft 11 and the mounting part 171 of the sliding member 17, and are located on the side of the first gear 12 and the second gear 13 facing away from the first end of the rotating shaft 11, which can ensure the meshing stability of the first gear 11 and the second gear 12, and thus ensure the stability of the meshing transmission of the first gear 12 and the second gear 13.
[0037] like Figure 4 , Figure 10 As shown, when the angle between the first housing 21 and the second housing 22 is 0 degrees, the electronic device is in the off state. The first ends of the second link 19 and the first link 14 are close together. As the first housing 21 opens, the angle between it and the second housing 22 increases, synchronously driving the rotating shaft 11 and the first gear 12 to rotate counterclockwise, which in turn drives the meshing second gear 13 to rotate clockwise. The second gear 13 then synchronously drives the first end of the first link 14 to rotate. Because the second end of the first link 14 is pivotally connected to the fixing member 18, there is no relative displacement between the second end of the first link 14 and the fixing member 18. Therefore, the first link 14 pushes the second gear 13, the first gear 12, and the rotating shaft 11 in the opposite direction, causing the rotating shaft 11 to drive the second end of the sliding member 17 to slide away from the sliding hole 181 of the fixing member. The distance between the rotating shaft 11 and the fixing member 18 gradually increases. Figure 5 , Figure 11As shown. This causes the first housing 21 to move away from the second housing 22 relative to the second housing 22, and the space of the heat dissipation vent on the first side of the second housing, which is located near the hinge structure 1, is also increased, thereby improving the heat dissipation efficiency of the heat dissipation module of the electronic device and reducing heat recirculation.
[0038] Furthermore, such as Figure 2 As shown, a stop plate 113 is also fixedly installed at the second end of the rotating shaft 11. The stop plate 113 is located on the side of the second connecting rod 19 facing away from the first end of the rotating shaft 11. The stop plate 113 is used to prevent the second connecting rod 19 from falling off the rotating shaft 11 and to prevent the second gear 13 from falling off the sliding member.
[0039] In one possible implementation, such as Figure 6 As shown, the rotating shaft 11 is provided with a protrusion 111, and a sleeve 112 is provided between the protrusion 111 and the first end of the sliding member 17 and sleeved on the rotating shaft.
[0040] like Figure 3 , Figure 6 As shown, a sleeve 112 is provided between the protrusion 111 and the first end of the slider 17. The sleeve 112 can ensure the installation position of the slider 17 and the first gear 12 on the rotating shaft 11 and adjust the distance between the first gear 12 and the first end of the rotating shaft 11.
[0041] Furthermore, such as Figure 7 As shown, a hinge cover 23 is also provided on the outside of the first end of the pivot 11 of the hinge structure 1. The hinge cover 23 can prevent the internal parts of the hinge structure 1 from being exposed when it moves.
[0042] Furthermore, such as Figure 8 As shown, the hinge structure 1 of this application also includes an outer appearance component 24. The first end of the sliding component 17 is fixedly connected to the outer appearance component 24. The outer appearance component 24 is movably connected between the first housing component 21 and the second housing component 22. When the sliding component 17 slides along the sliding hole 181 of the fixing component 18, it can synchronously drive the outer appearance component 24 to move. The outer appearance component 24 can cover external parts, so that the moving hinge structure 1 is not exposed.
[0043] In one possible implementation, such as Figure 1-3 As shown, the hinge structure 1 of this application also includes a torque component 16, which is connected to the first end of the rotating shaft 11. The torque component 16 is configured to form a stable circumferential damping torque when the first shell 21 rotates relative to the second shell 22, so that the first shell 21 remains at any rotation angle. Mounting bracket 15 is disposed between torque assembly 16 and protrusion 111, with the first end of mounting bracket 15 sleeved on rotating shaft 11 and the second end of mounting bracket 15 fixedly connected to first housing 21.
[0044] When the first housing 21 of the electronic device 2 is rotated open to a certain angle relative to the second housing 22, the torque assembly 16 can hold the first housing 21 at that rotation angle.
[0045] Specifically, such as Figure 6 As shown, the torque assembly 16 includes multiple adjacent torque plates (such as butterfly washers or friction plates) 161 and a torque nut 162. The multiple torque plates are stacked along the axial direction of the rotating shaft 11, and the torque nut 162 is screwed to the first end of the rotating shaft 11. The torque plate 161 abuts against the mounting bracket 15 through the torque nut 162. At least two adjacent butterfly washers 161 can form an assembly deformation gap. When the torque assembly 16 is subjected to torque, the torque plates 161 undergo elastic adaptation deformation due to friction during relative movement, and are correspondingly squeezed and filled into the assembly deformation gap. This allows the torque assembly 16 to form a stable circumferential damping torque, so that the first housing 21 remains stationary at any rotation angle.
[0046] The first end of the mounting bracket 15 is sleeved on the rotating shaft 11, and the second end of the mounting bracket 15 can be provided with rivet holes or screw holes, etc., for the purpose of installing the first housing 21.
[0047] Secondly, such as Figure 8-11 As shown, this application also provides an electronic device 2, including a first housing 21 and a second housing 22, the first side of the second housing 22 having a heat dissipation vent; it also includes a hinge structure 1 as described in any of the above embodiments, the first side of the second housing 22 being movably connected to the first housing 21 through the hinge structure 1; when the first housing 21 rotates relative to the second housing 22, it drives the rotating shaft 11 and the first gear to rotate, so that when the second gear rotates under the meshing transmission of the first gear, it drives the first end of the first connecting rod to move away from or towards the rotating shaft, thereby realizing that when the first housing 21 rotates relative to the second housing 22, the connecting axis of the first housing 21 and the rotating shaft 11 moves towards or away from the heat dissipation vent of the second housing.
[0048] For example, the second housing 22 has a heat dissipation vent on the first side near the hinge structure 1. As the opening angle between the first housing 21 and the second housing 22 gradually increases, the gap between the connecting axis of the first housing 21 and the rotating shaft 11 and the heat dissipation vent gradually increases.
[0049] Taking a laptop computer as an example, the first shell 21 is the B part of the laptop computer, the second shell 22 is the C part of the laptop computer (i.e., the shell where the keyboard is located), and the third shell is the D part (bottom shell) of the laptop computer. A heat dissipation module is installed in the cavity formed between the second shell 22 and the third shell 25 (the D part of the laptop computer). In order to ensure that the heat generated by the heat dissipation module can be dissipated smoothly to the outside, the second shell 22 has a heat dissipation vent on the first side near the hinge position, so that the heat generated by the heat dissipation module can be dissipated to the outside. However, in the current related technology, the space of the heat dissipation vent is blocked by the hinge cover of the hinge, which limits the heat dissipation efficiency of the heat dissipation module. Therefore, in order to increase the heat dissipation efficiency of the heat dissipation module and reduce heat backflow, this application connects the first shell 21 and the second shell 22 by setting a hinge structure 1.
[0050] The first housing 21 is fixedly connected to the mounting bracket 15 of the hinge structure 1, and the second housing 22 is fixedly connected to the fixing member 18 of the hinge structure 1. The fixing member 18 and the second housing 22 are arranged parallel to each other (e.g., Figure 12 (As shown) Explanation: like Figure 4 , Figure 10 As shown, when the first housing 21 and the second housing 22 are closed, the angle between them is 0 degrees. At this time, the first gear 12 and the second gear 13 are meshed. The first end of the first connecting rod 14 and the second connecting rod 19 are arranged in an up-down position and partially overlap along the vertical direction. At this time, the distance between the rotating shaft 11 and the fixing member 18 is the smallest.
[0051] like Figure 5 , Figure 11 As shown, when the first shell 21 is opened by rotating counterclockwise, the angle between the first shell 21 and the second shell 22 gradually increases. The rotating shaft 11 synchronously drives the first gear 12 to rotate counterclockwise, and the second gear 13 to rotate clockwise, simultaneously driving the first end of the first connecting rod 14 to rotate. This causes the first connecting rod 14 to push the fixing member 18 away from the second gear 13. Since the fixing member 18 is fixedly connected to the second shell 22, and the second shell 22 and the third shell 25 of the laptop are generally placed on a flat surface (e.g., a desktop), the friction and gravity between the third shell 25 and the desktop are much greater than the pushing force of the first connecting rod 14 on the fixing member 18. Therefore, the first connecting rod 14 pushes the second gear 13, the first gear 12, and the rotating shaft 11 to move synchronously away from the fixing member 18. This causes the rotating shaft 11 to drive the second end of the sliding member to slide away from the sliding hole 181, and simultaneously drives the first shell 21 to translate away from the second shell 22. Figure 12(as shown by the arrow), thereby increasing the space for the heat dissipation vent at the hinge structure 1, improving the heat dissipation efficiency of the heat dissipation module, reducing heat recirculation, and without affecting the overall size of the machine.
[0052] Of course, such as Figure 13 As shown, when the fixing member 18 and the second shell member 22 are set at an acute angle, when the first shell member 21 is opened by rotating counterclockwise, the first shell member 21 will move obliquely away from the second shell member 22 simultaneously. Figure 13 (As shown by the arrow), the oblique movement direction is parallel to the second plane where the sliding hole 181 is located, further increasing the space of the heat dissipation vent at the hinge structure 1 and improving the heat dissipation efficiency of the laptop.
