Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a fixed device and electronic equipment. Background Technology

[0002] In electronic devices, heat sinks are typically mounted on components to dissipate heat. In related technologies, since components often have different dimensions, heat sinks with sizes that match the component's dimensions are required. However, this approach necessitates designing multiple heat sinks of different sizes, resulting in material waste and high costs. Alternatively, a heat sink can be added to a larger component to meet better heat dissipation requirements; however, this approach requires repeated installation of heat sinks, which is time-consuming, labor-intensive, and affects the efficiency of the installation between the heat sink and the component.

[0003] Therefore, there is an urgent need to develop a new type of fixing device so that the heat sink can be adapted to heat dissipation components of different sizes. Utility Model Content

[0004] This application provides a fixing device and an electronic device to at least solve the above-mentioned problems in the related art.

[0005] To achieve the above objectives, this application provides the following technical solution: a fixing device, which includes a heat sink and a fixing component;

[0006] The heat sink has a stop at one end in the length direction and multiple fixing positions are provided at intervals in the length direction. The heat sink is detachably connected to the fixing position at each fixing position.

[0007] In the fixed state, the fixing member and the stop body abut against the opposite ends of the component to be cooled, so as to clamp and fix the component to be cooled; wherein,

[0008] The fasteners are detachably connected to different fixing positions on the heat sink to clamp and fix components of different sizes to be cooled.

[0009] In some alternative implementations, the fastener is snapped into the heat sink, and the fastener is snapped into different fixing positions on the heat sink to fix components of different sizes to be cooled.

[0010] In some optional embodiments, the heat sink has heat dissipation sidewalls at both ends in the width direction, the component to be dissipated is located between the two heat dissipation sidewalls, each heat dissipation sidewall has multiple snap-fit ​​holes, the multiple snap-fit ​​holes are spaced apart along the length direction of the heat sink, and each snap-fit ​​hole is located at a corresponding fixed position.

[0011] The fastener has retaining members at both ends of the heat sink in the width direction, and each retaining member is adapted to the corresponding snap-fit ​​hole;

[0012] In the fixed state, the fastener engages with the snap-fit ​​hole via the snap-fit ​​element.

[0013] In some alternative embodiments, the fastener has grooves at both ends in the width direction of the heat sink, and the grooves are slidably connected to the corresponding heat sink sidewalls to adjust the position of the fastener in the length direction of the heat sink.

[0014] The outer wall of the groove forms a retaining element, which engages with the retaining hole.

[0015] In some alternative embodiments, the retaining member is made of an elastic material, and an actuating member is connected to the outside of the retaining member. When an external force is applied to the actuating member, the actuating member causes the retaining member to undergo elastic deformation, so that the retaining member disengages from the locking hole.

[0016] In some optional embodiments, a positioning groove is provided at one end of the component to be cooled facing the fixing member, and the fixing member is also provided with positioning parts and bearing parts spaced apart along the thickness direction of the component to be cooled; the positioning parts are located on one side of the component to be cooled, and the bearing parts are located on one side of the component to be cooled and extend toward the middle region of the heat sink.

[0017] In the fixed state, the positioning part is located in the positioning groove to position the component to be cooled, and the component to be cooled is supported on the support part.

[0018] In some alternative embodiments, one end of the heat sink with a stop body is also connected to a bent portion, which extends toward the middle region of the heat sink, and the end of the component to be cooled that is away from the fixing member is supported on the bent portion.

[0019] In some alternative embodiments, this application also provides an electronic device, including the fixing device, the heat dissipation component, and the assembly component as described above;

[0020] The component to be cooled is located on the side of the heat sink facing the component to be assembled, and the end of the heat sink away from the stop body in the length direction is detachably connected to the component to be assembled.

[0021] The component to be cooled is detachably connected to the component to be assembled at one end abutting against the stop body along the length of the heat sink.

[0022] In some alternative implementations, the end of the component to be cooled near the stop is mechanically and electrically connected to the component to be assembled via a connector;

[0023] The end of the heat sink that is away from the stop body is detachably connected to the component to be assembled via a locking device.

[0024] In some alternative implementations, a gap is formed between the heat sink and the component to be assembled via connectors and locking elements to create an installation space for the component to be cooled between the heat sink and the component to be assembled.

[0025] In the aforementioned fixing device, by detachably connecting the fixing member to different fixing positions on the heat sink and cooperating with the stop body to abut against the opposite sides of the component to be cooled, components of different sizes to be cooled can be clamped and fixed, thereby meeting the heat dissipation requirements of components of different sizes to be cooled.

Detailed Implementation

[0034] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0037] In related technologies, since the components to be cooled usually have different sizes, heat sinks that are compatible with the size of the components need to be used. However, this approach requires designing multiple heat sinks of different sizes, which wastes materials and is costly. Alternatively, a heat sink can be added to a larger component to meet the cooling requirements. However, this approach requires repeated installation of heat sinks, which is time-consuming and labor-intensive, and affects the installation efficiency between the heat sink and the component to be cooled.

[0038] To solve the above problems, researchers discovered that by using a larger heat sink to cover and accommodate components of various sizes, and by designing movable fixing parts, the heat sink can be moved to different positions and fixed to components of different sizes, thus achieving a fixed connection between the heat sink and components of different sizes.

[0039] Therefore, combining Figure 1In some embodiments, this application discloses a fixing device 10, which includes a heat sink 11 and a fixing member 12. The heat sink 11 has a stop 112 at one end in the length direction and a plurality of fixing positions 111 spaced apart in the length direction. The heat sink 11 is detachably connected to the fixing member 12 at each fixing position 111. In the fixed state, the fixing member 12 and the stop 112 abut against the opposite ends of the component 20 to be cooled, thereby clamping and fixing the component 20. The fixing member 12 is detachably connected to different fixing positions 111 on the heat sink 11 to clamp and fix components 20 of different sizes to be cooled, allowing the component 20 to dissipate heat through the heat sink 11. For example, the component 20 to be cooled can be a solid-state drive. Figure 1 This is a structural diagram of the fixing device and the components to be cooled.

[0040] In the aforementioned fixing device 10, the fixing member 12 is detachably connected to different fixing positions 111 on the heat sink 11 and cooperates with the stop body 112 to abut against the opposite sides of the heat sink 20, so as to clamp and fix the heat sink 20 of different sizes, thereby meeting the heat dissipation requirements of the heat sink 20 of different sizes.

[0041] It should be noted that, since the heat sink needs to be adapted to components of different lengths, it is designed as a cuboid structure with a large length. The larger component has a larger heat dissipation area and better heat dissipation effect. In addition, it has length, width and thickness. For ease of explanation, this application uses the length direction, width direction and thickness direction of the heat sink as reference directions for description.

[0042] In some preferred embodiments, the stop 112 is a bent structure extending from the heat sink 11, and it is an integral structure with the heat sink 11.

[0043] In some preferred embodiments, the heat sink 11 can be a heat sink frame structure made of aluminum alloy, copper-aluminum composite material, aluminum-based composite material, magnesium alloy material, graphene material, etc., or it can be a heat sink structure, such as a water-cooled heat sink.

[0044] It is understandable that the fixing position 111 on the heat sink 11 refers to the fixing position of the fixing member 12 on the heat sink 11 when the fixing member 12 is pressed against the heat sink component 20 of the corresponding size and specification.

[0045] In some optional embodiments, the fixing member 12 and the heat sink 11 are detachably connected by a threaded structure. Multiple threaded holes are arranged at intervals along the length of the heat sink 11. When fixing heat sink components 20 of different sizes, the fixing member 12 moves to the corresponding fixing position 111 and is threadedly connected to the threaded hole by a screw, and abuts against the heat sink component 20, thereby fixing heat sink components 20 of different specifications.

[0046] Combination Figure 1 In some alternative embodiments, the fastener 12 is snapped onto the heat sink 11 and the snapping is used to achieve a detachable connection. The fastener 12 is snapped onto different positions on the heat sink 11 to fix the heat sink components 20 of different sizes.

[0047] Thus, the snap-fit ​​usually achieves direct engagement between the fastener 12 and the heat sink 11 through mechanical structures (e.g., slots, buckles, or bosses), without the need for additional fasteners such as screws and disassembly tools, which can significantly shorten the assembly time. Furthermore, no additional disassembly tools are required during disassembly and assembly, making the disassembly and assembly between the fastener 12 and the heat sink 11 more convenient.

[0048] It should be noted that the detachable connection structure between the fixing member 12 and the heat sink 11 listed above is merely an example, and this application does not limit the specific detachable connection structure.

[0049] Combination Figure 1 In some embodiments, the heat sink 11 has heat dissipation sidewalls 113 at both ends in the width direction, and the component to be dissipated 20 is located between the two heat dissipation sidewalls 113. Each heat dissipation sidewall 113 is provided with a plurality of snap-fit ​​holes 114, which are spaced apart along the length direction of the heat sink 11, and each snap-fit ​​hole 114 is located at a corresponding fixing position 111; combined with Figure 2 The fixing member 12 has a retaining member 121 at both ends of the heat sink 11 in the width direction. Each retaining member 121 is adapted to the corresponding snap-fit ​​hole 114. In the fixed state, the fixing member 12 is snapped into the snap-fit ​​hole 114 through the retaining member 121. Figure 2 This is a structural schematic diagram of the fastener.

[0050] Thus, the fastener 12 engages with the two heat dissipation sidewalls 113 via the retaining members 121 at both ends, which not only limits the fastener 12 in the width direction but also improves the engagement stability between the fastener 12 and the heat dissipation component 11. At the same time, the heat dissipation sidewalls 113 increase the heat dissipation area and improve the heat dissipation efficiency of the heat dissipation component 11. Furthermore, the engagement holes 114 are distributed along the length direction, allowing the fastener 12 to be precisely positioned in the length direction, thereby adapting to heat dissipation components 20 of different sizes.

[0051] Combination Figure 2 In some embodiments, the fixing member 12 is provided with sliding grooves 122 at both ends in the width direction of the heat sink 11. The sliding grooves 122 are slidably connected to the corresponding heat sink sidewalls 113 to adjust the position of the fixing member 12 in the length direction of the heat sink 11. The outer sidewall of the sliding groove 122 forms a retaining member 121, which engages with the retaining hole 114.

[0052] Thus, the sliding groove 122 allows the fixing member 12 to move smoothly in the length direction, and the adjustment does not need to be separated from the heat sink 11. The matching fixing position 111 can be found quickly, thereby improving the adjustment efficiency. At the same time, the sliding groove 122 can form a guide structure with the heat sink side wall 113 to prevent the fixing member 12 from tilting during the adjustment process, thereby ensuring the alignment accuracy of the holding member 121 and the snap-fit ​​hole 114, which is conducive to quickly completing the snap-fit ​​action.

[0053] Combination Figure 2 In some embodiments, the retaining member 121 is made of an elastic material, and an actuating member 123 is connected to the outside of the retaining member 121. When an external force is applied to the actuating member 123, the actuating member 123 causes the retaining member 121 to undergo elastic deformation, so that the retaining member 121 disengages from the locking hole 114. For example, the elastic material can be spring steel.

[0054] Thus, the retaining member 121, made of elastic material, can compensate for the manufacturing tolerances between itself and the locking hole 114. Even with slight dimensional deviations, it can still achieve a tight lock-on through elastic deformation. At the same time, the retaining member 121, made of elastic material, can automatically extend into the locking hole 114 and remain locked in the absence of external force, thereby achieving automatic locking and fixing. It can also prevent the retaining member 121 from automatically disengaging due to equipment vibration, ensuring the reliability of locking and fixing. Moreover, by triggering the elastic deformation of the retaining member 121 by moving the actuating member 123, the retaining member can be released or installed without the need for external tools, making disassembly or installation more efficient.

[0055] Combination Figure 2 In some embodiments, the end of the component 20 to be cooled facing the fixing member is provided with a positioning groove, and the fixing member 12 is also provided with a positioning part 124 and a supporting part 125 spaced apart along the thickness direction of the component 20 to be cooled; the positioning part 124 is located on one side of the component 20 to be cooled (that is, the upper region of the component 20 to be cooled), and the supporting part 125 is located on one side of the component 20 to be cooled (that is, the lower region of the component 20 to be cooled), and both the positioning part 124 and the supporting part 125 extend toward the middle region of the heat sink 11; in the fixed state, the positioning part 124 is located in the positioning groove to position the component 20 to be cooled, and the component 20 to be cooled is supported on the supporting part 125.

[0056] Thus, by cooperating with the positioning part 124 and the positioning groove, the movement of the component to be cooled 20 in the plane is restricted, thereby achieving the positioning of the component to be cooled 20. At the same time, by supporting the weight of the component to be cooled 20 through the bearing part 125, the stress concentration caused by the component to be cooled 20 bearing only the clamping force formed by the fixing part 12 and the stop body 112 is avoided, which effectively reduces the wear of the component to be cooled 20. Moreover, it can also improve the stability of the component to be cooled 20 after installation and prevent the component to be cooled 20 from affecting the connection stability with other components due to gravity sagging.

[0057] Combination Figure 1 In some embodiments, one end of the heat sink 11 with a stop 112 is also connected to a bending portion 115. The bending portion 115 extends toward the middle region of the heat sink 11, and the end of the heat sink component 20 facing away from the fixing member is supported on the bending portion 115.

[0058] Thus, the bent portion 115 cooperates with the bearing portion 125 of the fixing member 12 to support both ends of the heat dissipation component 20, and cooperates with the bearing portion 125 to form a stable bearing structure in the thickness direction of the heat dissipation component 11, preventing the heat dissipation component 20 from swaying in the thickness direction. At the same time, the support of the bent portion 115 reduces the direct pressure on the stop body 112 from the end of the heat dissipation component 20 away from the fixing member. The stop body 112 does not need to overcome the weight of the heat dissipation component 20 through friction, which helps to reduce the squeezing force between the stop body 112 and the heat dissipation component 20, and avoids damage to the stop body 112 due to excessive local squeezing force between the stop body 112 and the heat dissipation component 20, thereby extending the service life of the fixing device 10.

[0059] In some preferred embodiments, the heat sink 11, the heat sink sidewall 113, the stop body 112, and the bending portion 115 are an integral structure.

[0060] Combination Figure 3 In some embodiments, this application also provides an electronic device, including the fixing device 10 as described above, a heat-dissipating component 20, and a component to be assembled 30; the heat-dissipating component 20 is disposed on the side of the heat sink 11 facing the component to be assembled 30, and the end of the heat sink 11 away from the stop body 112 in the length direction is detachably connected to the component to be assembled 30; the end of the heat sink 20 abutting against the stop body 112 in the length direction of the heat sink 11 is detachably connected to the component to be assembled 30. For example, the heat-dissipating component 20 can be a solid-state drive, and the component to be assembled 30 can be a circuit board. Figure 3 This is a structural diagram of the fixing device 10, the heat dissipation component 20, and the assembly component 30.

[0061] In this way, the component to be cooled 20 and the component to be assembled 30 are detachably connected, so that the component to be cooled 20 can be disassembled and repaired separately when it fails, thereby reducing the maintenance cost of electronic equipment. At the same time, by placing the component to be cooled 20 on the side of the heat sink 11 facing the component to be assembled 30, the heat sink 11 has a larger heat dissipation space, resulting in better heat dissipation effect.

[0062] Furthermore, the component 20 to be cooled is placed against the side of the heat sink 11 facing the component 30 to be assembled, so that the heat on the component 20 to be cooled can be directly transferred to the outside through the heat sink 11.

[0063] Combination Figure 3 In some embodiments, the end of the heat dissipation component 20 near the stop body 112 is mechanically and electrically connected to the component 30 to be assembled via a connector 40; the end of the heat dissipation component 11 away from the stop body 112 is detachably connected to the component 30 to be assembled via a locking member 50. For example, the locking member 50 may be a screw.

[0064] During installation, the heat dissipation component 20 is first installed onto the heat sink 11, and then the heat dissipation component 20 with the heat sink 11 installed is installed onto the assembly component 30, thus integrating the functions of fixing the heat dissipation component 20, heat dissipation, and electrical connection with the assembly component 30.

[0065] Thus, the connector 40 simultaneously achieves both mechanical and electrical connections between the heat dissipation component 20 and the assembly component 30, ensuring stable signal transmission between components and avoiding poor contact. The locking component 50 locks and fixes the other end of the heat dissipation component 11 to the assembly component 30, further improving the connection stability between the heat dissipation component 20 and the assembly component 30. At the same time, the mechanical and electrical connections are achieved through a single connector 40, reducing the number of accessories, simplifying the structural design, and helping to reduce production costs.

[0066] Combination Figure 3 In some embodiments, a gap is formed between the heat sink 11 and the component 30 to be assembled via a connector 40 and a locking member 50, so as to form an installation space for the component 20 to be heat-suppressed between the heat sink 11 and the component 30 to be assembled. The height of the connector 40 and the length of the locking member 50 are matched to support the heat sink 11 together, so that the gap is formed between the heat sink 11 and the component 30 to be assembled.

[0067] Thus, by designing a gap between the heat sink 11 and the component to be assembled 30, installation space is reserved for the component to be cooled 20, avoiding interference between them; at the same time, the gap design forms an airflow channel, creating an airflow space between the component to be cooled 20 and the component to be assembled 30, thereby improving the heat dissipation effect of the component to be cooled 20 and preventing performance degradation due to heat accumulation; moreover, the component to be assembled 30 can also dissipate heat through this airflow channel.

[0068] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
