Description

Technical Field

[0001] This invention belongs to the field of electronic equipment technology, and specifically relates to a heat dissipation device and an electronic device. Background Technology

[0002] Currently, with the increasing prevalence of laptop users, there is a growing focus on performance, user experience, and personalized design. In particular, the effectiveness of heat dissipation is becoming a key factor for most laptop buyers, especially those using gaming laptops. Since one of the initial design goals of laptops was portability, they are typically small and thin. Combined with the thickness of the keyboard, screen, and motherboard, the space available for heat dissipation is very limited, making heat dissipation a persistent challenge. Experimental test data shows that without additional cooling, infrared devices can detect temperatures exceeding 74 degrees Celsius in the keyboard area corresponding to the processor and GPU during laptop use. This significantly impacts the laptop's operating speed and user experience, resulting in a less than satisfactory user experience.

[0003] Current solutions for heat dissipation in electronic devices (such as laptops) are limited by the overall thickness and structural space of laptops. These solutions primarily rely on internal fans and external auxiliary cooling methods (exhaust fans and heat sinks). However, this approach still doesn't provide a satisfactory solution for heat dissipation. The internal cooling fan's limited space prevents the generated heat from being effectively utilized by the primary heat-generating areas, thus failing to achieve the desired cooling effect. Furthermore, adding external cooling methods not only increases costs but also inconveniences users, hindering portability. Summary of the Invention

[0045] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but these are not intended to limit the scope of the invention. To enable those skilled in the art to better understand the technical solutions of this disclosure, the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments.

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0047] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0048] It should be noted that, in order to facilitate the understanding of the technical solution, especially the technical solution of the present invention in combination with pictures and text, the parts to be adjusted and the keyboard support frame will use the same markings in the following description.

[0049] With the miniaturization of electronic devices, especially small gaming devices, there are unusually high requirements for heat dissipation. However, due to the limited space corresponding to the overall thickness of the electronic device, how can we increase the space available for heat dissipation within this limited space to support improved heat dissipation efficiency? To this end, the present invention provides the following design solution.

[0050] On one hand, embodiments of the present invention provide a heat dissipation device, see [link to previous document]. Figures 1 to 9The device rotatably connects two mounting surfaces opposite to the first body 1 and the second body of the electronic device. The mounting surface of the second body has an adjustment component 17. The heat dissipation device includes a transmission mechanism, a helical gear assembly 15, and a locking mechanism. The transmission mechanism includes an active part and a driven part. The active part spans between the first body 1 and the second body and drives the driven part as the first body 1 and the second body open or close. The helical gear assembly 15 includes a first helical gear 151, a second helical gear 152, and an energy storage component. The first helical gear 151 and the second helical gear 152 mesh with each other and follow the driven part. The energy storage component is fixedly connected to the second helical gear 152 at one end away from the first helical gear 151. The first helical gear 151 extends radially on its circumferential surface in a direction away from its axis to form a lever 18. The lever 18 is connected to... The component to be adjusted 17 is slidably connected; the locking mechanism includes a knob 12 and a locking block 26 with a latch 14; the knob 12 and the locking block 26 are fixedly connected; the latch 14 presses against the surface of the component to be adjusted 17 from above; when the first body 1 and the second body are open to each other, the second helical gear 152 applies a force to the energy storage component to store energy; the knob 12 is turned, causing the locking block 26 to move away from the component to be adjusted 17, and the latch 14 moves away from the upper surface of the component to be adjusted 17; the energy storage component releases energy and pushes the second helical gear 152; the second helical gear 152 drives the first helical gear 151 to rotate, and through the first helical gear 151 drives the lever 18 to rotate, so that the component to be adjusted 17 moves away from the mounting surface of the second body. In this embodiment of the invention, by adjusting the distance between the component to be adjusted 17 and the second body, the space for heat dissipation is increased accordingly, thereby improving the heat dissipation efficiency.

[0051] In this embodiment, combined with Figures 1 to 9 The second body can be constructed as a back cover 20; the component to be adjusted 17 can be constructed as a keyboard 21 and a keyboard support frame 17 connected to each other; a relatively closed space is formed between the keyboard 21 and the back cover 20. For ease of description and understanding, the component to be adjusted 17 can also be further understood as the keyboard support frame 17, and the two will be referred to by the same designation in this description.

[0052] Based on the design concept of this invention, without changing the dimensions of the keyboard 21 and the back cover 20, the distance between the keyboard 21 and the back cover 20 is changed by altering the height of the keyboard 21 relative to the back cover 20, thereby changing the size of the enclosed space. For example, when the lever 18 is raised around the driven page axis 23, the keyboard 21 is raised by driving the keyboard support frame 17 to rotate, thereby increasing the distance between the keyboard 21 and the back cover 20, thus increasing the volume of the enclosed space for heat dissipation. By accelerating gas flow, heat exchange with the outside is achieved, thereby improving heat dissipation efficiency. Furthermore, combined with... Figures 1 to 4 The active unit includes: an active page shaft 5, a first page 2, a second page 8, an active gear 3, a crossbeam 36, and a first support arm 101 and a second support arm 102 arranged in parallel. A receiving gap is formed between the first support arm 101 and the second support arm 102. One end of each of the first support arm 101 and the second support arm 102 is rotatably connected to the active page shaft 5. The other end of each is connected to the crossbeam 36 located within the receiving gap. The first page 2 is fixedly connected to the first body 1 and the active page shaft 5. The second page 8 is fixedly connected to the mounting surface of the second body and the first support arm 101. The active gear 3 is fixedly connected to the active page shaft 5 in a coaxial manner within the receiving gap. To prevent the active page shaft 5 from scratching against the outside, the active unit may also include a rotating shaft housing 7. The rotating shaft housing 7 is fixedly connected to the active page shaft 5 and the first page 2, and covers the active page shaft 5 from its end. Rotating the first page 2 drives the active page shaft 5 to rotate through the rotating shaft housing 7. The structure of the pivot housing 7 is not limited here, as long as it matches the shape of other components. For example, its shape can be adjusted accordingly based on the shape of other components, without affecting its function.

[0053] Furthermore, to enable the second page 8 to adapt to spaces with different heights and facilitate quick installation of the second page 8, in the above embodiment, a fixing block 9 can also be added, combined with... Figures 1 to 3 The fixing block 9 is fixed to the mounting surface of the second body, and the second sheet 8 is fixed to the fixing block 9, thereby connecting to the mounting surface of the second body. By adjusting the thickness of the fixing block 9, the second sheet 8 can be adapted to different spatial heights. In addition, in the above embodiment, the second sheet 8 and the first support arm 101 can also be integrally formed, thereby improving physical properties and correspondingly increasing service life.

[0054] Furthermore, combined Figures 1 to 4The driven part includes: a driven page shaft 23, a first driven gear 4 and a second driven gear 6; wherein the first driven gear 4 and the second driven gear 6 are rotatably connected to the first support arm 101 and the second support arm 102 within the accommodating gap; the driving gear 3, the first driven gear 4 and the second driven gear 6 mesh sequentially; the driven page shaft 23 is located on the side of the second support arm 102 away from the first support arm 101 and is fixedly connected to the second driven gear 6 in a coaxial manner.

[0055] In this embodiment, a crossbeam 36 is provided to form a stable support frame between the driving gear 3, the crossbeam 36, the first support arm 101, and the second support arm 102, thereby maintaining transmission stability during the operation of the driven part. For example, by driving the driving gear 3, the first driven gear 4 and the second driven gear 6 are rotated. Due to the good support provided by the support frame, the force transmission is uniform during gear transmission, thereby correspondingly improving the service life of the transmission components. In this embodiment, the smoothness of the first body 1 and the second body when their relative positions change can also be improved by adjusting the tooth density 62 of the transmission gears. In addition, the driving gear 3 and the driving leaf shaft 5, and the second driven gear 6 and the driven leaf shaft 23 can all be integrally formed.

[0056] Furthermore, combined Figure 4 and Figure 7 The first helical gear 151 is located on the other side of the second support arm 102 opposite to the second driven gear 6, and is fixedly connected to the driven page shaft 23 coaxially. Furthermore, in this embodiment, the second driven gear 6 and the driven page shaft 23 are configured to be coaxial. With this configuration, when the second driven gear 6 is rotating, it can simultaneously drive the driven page shaft 23 to rotate and also drive the first helical gear 151 to rotate.

[0057] Furthermore, combined Figure 4 and Figure 7The energy storage component is constructed as a return spring 16, which is sleeved on the driven page shaft 23. The first helical gear 151 and the second helical gear 152 are constructed as inclined surfaces on their axially opposite surfaces. By setting the inclined surfaces, the conversion between axial force and rotational torque can be realized. When the first body 1 and the second body are open relative to each other, and the latch 14 presses against the component to be adjusted 17, the second helical gear 152 converts the radial torque into an axial force acting on the return spring 16, so that the return spring 16 stores energy. When the first body 1 and the second body are closed relative to each other, the return spring 16 pushes the second helical gear 152, converting the axial force into a radial torque through the inclined surfaces, driving the first helical gear 151 to rotate, and driving the lever 18 to rotate, pulling the keyboard support frame 17 to move towards the second body. Of course, in addition to the above states, when the latch 14 is not pressing the component to be adjusted 17, the first body 1 and the second body are closed, that is, the first body 1 and the second body are shut off. At this time, the component to be adjusted 17, driven by the driven part, is directly moved towards the mounting surface of the second body by the lever 18. In conjunction with the above embodiment, when the latch 14 is not pressing the component to be adjusted 17, the keyboard support frame 17 is raised, the volume of the enclosed space increases, and it enters a heat dissipation state; and when the latch 14 presses the component to be adjusted 17, the keyboard support frame 17 falls back down, returning from the heat dissipation state to the initial state. Here, the initial state can be understood as the input state for the user's convenience in using the input terminal, or the state when the first body 1 and the second body are closed. It can be seen that the heat dissipation device of this embodiment improves heat dissipation efficiency by changing the size of the heat dissipation space. Furthermore, in conjunction with... Figures 5 to 9 The first driven gear 4 is provided with a rocker arm 51; the rocker arm 51 extends radially outward from the end side of the first driven gear 4 near the first support arm 101; a protruding post 52 is provided on the free end of the rocker arm 51 facing the second support arm 102; the second driven gear 6 is constructed as an irregular gear; the second driven gear 6 includes a hub 61 and adjacent and spaced teeth 62; the teeth 62 are fixed to the outer circumferential surface of the hub 61 and mesh with the protruding post 52 of the first driven gear 4 within a preset angle range. In this embodiment, see... Figure 6A U-shaped groove is formed between two opposing gear teeth 62, and the two opposing inner wall surfaces of the U-shaped groove are parallel to each other. By adjusting the width between the inner wall surfaces of the U-shaped groove, the span between the gear teeth 62 is adjusted, thereby changing the meshing stroke between the second driven gear 6 and the first driven gear 4. Correspondingly, the rotation angle of the driven page shaft 23 is adjusted, and the height of the lever 18 is further adjusted. Finally, the distance between the keyboard support frame 17 and the second body is adjusted, that is, the distance between the keyboard 21 and the back cover 20 is adjusted. In this embodiment, the protruding column 52 is constructed as a cylindrical structure, and its axis is parallel to the gear axis of the first driven gear 4 and the second driven gear 6, respectively. In addition, in order to make the meshing stroke smooth, the outer surface of the two gear teeth 62 away from the U-shaped groove is constructed as a curved surface; the specific structure of the curved surface is not further limited here, as long as it can satisfy the smooth movement of the first body 1 and the component to be adjusted 17.

[0058] Furthermore, combined Figures 4 to 9 The helical gear assembly 15 also includes a pin 19; a lever 18 has a through hole at its end away from the first helical gear 151; the lever 18 is arranged adjacent to the component to be adjusted 17; the component to be adjusted 17 is configured as a plate structure; a slide rail 24 is provided on the side of the component to be adjusted 17 near the lever 18; both ends of the pin 19 are respectively inserted through the slide rail 24 and the through hole to form a sliding connection between the lever 18 and the component to be adjusted 17. In this embodiment, the axis of the pin 19 is arranged parallel to the axes of the driving page shaft 5 and the driven page shaft 23. Further, it can also be arranged parallel to the axes of the driving gear 3, the first driven gear 4, and the second driven gear 6. In this embodiment, depending on the actual application scenario, the slide rail 24 can be constructed as a through hole or a strip groove structure; the specific structure is not limited here.

[0059] In practical applications, based on different user habits, embodiments of the present invention also provide the following personalized design schemes to facilitate users to select operations according to their personal habits.

[0060] Furthermore, combined Figure 1 , Figure 2 , Figures 10 to 12The heat dissipation device further includes a guide mechanism 11; the guide mechanism 11 is connected to the second body; the locking mechanism further includes a crank connecting rod 25; the guide mechanism 11 includes: a guide body 27; a first pin 30, a first slide groove 28, and a second slide groove 29 disposed on the guide body 27; the crank connecting rod 25 is rotatably connected to the first pin 30 near its middle position; a dial 12 is embedded in the first slide groove 28; a locking block 26 is embedded in the second slide groove 29 and corresponds to the position of the component 17 to be adjusted; the two sides of the crank connecting rod 25 The ends of the first and second slides 28 and 29 respectively extend into their corresponding first slides 28 and 29, and are connected to the corresponding knobs 12 and locking blocks 26 at their two ends. When the knob 12 is turned, the knob 12 drives one end of the crank connecting rod 25 to rotate around the axis of the first pin 30, and drives the locking block 26 to move toward the component to be adjusted 17 through the other end of the crank connecting rod 25, so as to press the latch 14 against the upper surface of the component to be adjusted 17, thereby restricting the movement of the component to be adjusted 17 away from the mounting surface of the second body. In this embodiment, in order to improve the smooth movement of the latch 14, the surface of the tip of the latch 14 can be constructed as an arc. In addition, in this embodiment, the first slides 28 and the second slides 29 are arranged perpendicular to each other, but it is not limited to this. As long as the knob 12 can control the crank connecting rod 25 to rotate around the first pin 30 and make the locking block 26 move toward the component to be adjusted 17, the arrangement of the first slides 28 and the second slides 29 will not be further described or limited here.

[0061] In the above embodiments, combined with Figure 1 and Figure 2 The guide mechanism 11 may further include a cover 22; the cover 22 covers the guide body 27 and is fixedly connected to the guide body 27; the cover 22 may also be fixedly connected to the mounting surface of the second body at one end. Furthermore, the cover 22 has a through slot at a position corresponding to the toggle button 12, through which the toggle button 12 passes, facilitating user operation of the toggle button 12. By providing the cover 22, the operational reliability and service life of the toggle button 12 can be effectively improved.

[0062] Furthermore, the locking mechanism also includes a reset member 13, combined with... Figure 3 , Figures 7 to 9 The reset member 13 is located within the second slide groove 29 and is positioned along the direction of travel of the locking block 26. Both ends of the reset member 13 are connected to the guide body 27 and the locking block 26, respectively. The reset member 13 pulls the locking block 26 away from the component to be adjusted 17, thereby removing the latch 14 from the upper surface of the component to be adjusted 17. In this embodiment, the reset member 13 can be a spring, but is not limited to this.

[0063] Furthermore, combined Figures 10 to 12The guide mechanism 11 also includes a second pin 31 and a third pin 32. The second pin 31 is fixed to the guide body 27 and located within the second groove 29. The toggle switch 12 has a through hole 33 on one side. The crank connecting rod 25 has a first strip-shaped through groove 34 at the end corresponding to the toggle switch 12. The locking block 26 has a second strip-shaped through groove 35. The second pin 31 passes through the second strip-shaped through groove 35 to limit the movement range of the locking block 26. Specifically, the second pin 31 and the second strip-shaped through groove 35 work together to ensure that the locking block 26 can only move within the length range of the second strip-shaped through groove 35. The third pin 32 passes sequentially through the through hole 33 and the first strip-shaped through groove 34 to form a sliding connection between the crank connecting rod 25 and the toggle switch 12. In addition, in this embodiment, the crank connecting rod 25 and the locking block 26 are hinged. For example, the crank connecting rod 25 and the locking block 26 are hinged by a pin or shaft, but are not limited to this.

[0064] To clarify the working principle of locking block 26, a brief explanation is provided below:

[0065] See Figure 10 When the toggle switch 12 is moved from left to right, the toggle switch 12 passes through the third pin 32 (see...). Figure 12 The crank connecting rod 25 rotates clockwise around the first pin 30. The crank connecting rod 25, through its other end, pushes the locking block 26 within the second slide groove 29 in a direction toward the keyboard support frame 17, allowing the latch 14 to press against the upper surface of the keyboard support frame 17, preventing the keyboard support frame 17 from moving away from the back cover 20. In other words, in this state, the distance between the keyboard support frame 17 and the back cover 20 is always maintained as it is in the closed state of the first body 1 and the second body. When the toggle switch 12 is turned from right to left, the toggle switch 12, through the third pin 32, drives the crank connecting rod 25 to rotate counterclockwise around the first pin 30. Through cooperation with the reset member 13, it pulls the locking block 26 away from the keyboard support frame 17, causing the latch 14 to disengage from the upper surface of the keyboard support frame 17. At this time, the keyboard support frame 17 is lifted again under the action of the reset spring 16 and enters a heat dissipation state. On the other hand, an electronic device is provided that includes the aforementioned heat dissipation device or rotation limiting device.

[0066] To fully understand the structural features of the embodiments of the present invention, the following will further explain and illustrate them through actual operation procedures:

[0067] First, when the electronic device is not in use, the first body 1 and the second body of the electronic device are in a closed state. At this time, the latch 14 of the locking block 26 presses against the surface of the component to be adjusted 17.

[0068] In the second step, after entering the use state, the first body 1 and the second body are in an open state; during the process of opening the first body 1, the second helical gear 152 applies a force to the energy storage component (reset spring 16) (for example, the second helical gear 152 converts the radial torque into an axial force acting on the reset spring 16) so that the energy storage component stores energy;

[0069] Third, after the above operations, the user can perform operations on the input terminal (the component to be adjusted 17), such as text input or other operations;

[0070] Fourthly, to improve the system's heat dissipation, the dial 12 is turned, and the latch 14 moves away from the upper surface of the component to be adjusted 17. The energy storage component releases energy and pushes the second helical gear 152. The second helical gear 152 drives the first helical gear 151 to rotate, and through the first helical gear 151, drives the lever 18 to rotate, so that the component to be adjusted 17 moves away from the mounting surface of the second body, thereby increasing the distance between the component to be adjusted 17 and the second body, and thus improving the heat dissipation efficiency.

[0071] Fifth, based on the above steps, the latch 14 can be operated by turning the dial 12 according to the actual situation, so as to control the energy storage component to store and release energy, and correspondingly control and change the distance between the component to be adjusted 17 and the mounting surface of the second body, so as to switch between heat dissipation and other use states.
