[0041] The technical solutions of 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.

[0042] See Figures 1 to 5 As shown, an embodiment of the first aspect of this application discloses a fixing device, including a base assembly 100, a mounting member 200, a mounting base 500, a clamping assembly 300, and a spring member 400.

[0043] The base assembly 100 and the mounting member 200 are respectively disposed on the heat sink 600 and the motherboard 700, or the base assembly 100 and the mounting member 200 are respectively disposed on the motherboard 700 and the heat sink 600; the clamping assembly 300 is closably disposed on the base assembly 100 and is used to clamp the mounting member 200; the elastic member 400 is used to provide an elastic force acting on the clamping assembly 300 so that the clamping assembly 300 can be maintained in or reset to a closed position that can clamp the mounting member 200; the mounting base 500 is disposed on the motherboard 700 and is used to cooperate with the clamping assembly 300 to fix the heat sink 600.

[0044] In the embodiments of this application, the clamping assembly 300 is closed and clamps the mounting piece 200 by the force of the elastic component 400, and the heat sink 600 is installed on the motherboard 700 by the limiting position of the mounting base 500. When it is necessary to unlock, the clamping assembly 300 is opened and the mounting piece 200 is released, and the heat sink 600 is removed from the mounting base 500 to unlock the heat sink 600, thereby achieving the purpose of quick disassembly and assembly.

[0045] It should be understood that, under the force of the elastic component 400, the clamping assembly 300 is normally in its initial position. Before or during the installation of the mounting component 200, the clamping assembly 300 needs to be opened so that the clamping assembly 300 is in the open position. After the mounting component 200 is fixedly installed, it will be located between the open and closed positions of the clamping assembly 300. At this time, under the force of the elastic component 400, the clamping assembly 300 will return from the open position to the closed position and maintain it, thereby reliably closing and clamping the mounting component 200. The mounting base 500 is set on the motherboard 700 and is used to limit the heat sink 600. The mounting base 500 can cooperate with the clamping assembly 300 that has clamped the mounting component 200 to achieve the fixing effect of the heat sink 600. When the mounting component 200 leaves between the open and closed positions of the clamping assembly 300, the clamping assembly 300 will return from the closed position to the initial position and maintain it under the action of the elastic component 400.

[0046] It is understood that in some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the mounting base 500 is disposed on the motherboard 700 and initially limits the heatsink 600. The base assembly 100 is disposed on the heatsink 600, and the mounting member 200 is disposed on the motherboard 700. Under the force of the elastic member 400, the mounting member 200 is fixed by the clamping assembly 300 closing and clamping, thereby allowing the heatsink 600 to be quickly installed on the motherboard 700. For disassembly, simply loosen the clamping assembly 300 to release the mounting member 200 and remove the heatsink 600 from the mounting base 500, achieving a quick installation and removal effect. In some other embodiments, the base assembly 100 is disposed on the motherboard 700, and the mounting member 200 is disposed on the heatsink 600. In this case, the operation mode and principle of the fixing device of this application are similar to those described above, and therefore will not be further elaborated.

[0047] It should be noted that the mounting base 500 is used to fix the heat sink 600 in conjunction with the clamping assembly 300. In some embodiments, the mounting base 500 initially limits the heat sink 600 by means of detachable connection, abutment, or limiting. After the mounting component 200 is clamped by the clamping assembly 300, the mounting base 500 can cooperate with the clamping assembly 300 to achieve the effect of fixing the heat sink 600.

[0048] The following will combine Figures 1 to 5 The fixing device disclosed in the embodiments of this application will be explained and described in detail.

[0049] In some embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5The clamping assembly 300 includes a clamping arm component 310 and a lever component 320. The clamping arm component 310 and the lever component 320 are respectively hinged to the base assembly 100 to enable opening and closing. The mounting member 200 is located at the opening / closing point between the clamping arm component 310 and the lever component 320. It can be understood that the clamping arm component 310 cooperates with the lever component 320 to grip the fixing member when closed, while the lever component 320, in addition to its clamping function, also facilitates opening. When unlocking is required, a technician directly controls or uses an external power mechanism to drive the lever component 320, causing it to overcome the force of the spring component 400 and open, thereby unlocking the mounting member 200 and achieving the effect of removing the radiator 600.

[0050] In some embodiments, one end of the clamping arm component 310 and one end of the lever component 320 are respectively mounted on the base assembly 100 via hinge shafts. The clamping arm component 310 and the lever component 320 achieve the opening and closing effect of the clamping assembly 300 by relative movement. The other end of the lever component 320 is slightly longer than the other end of the clamping arm component 310 or is provided with a structure that facilitates the application of force, so that a technician or power mechanism can drive the lever component 320 to move relative to the lever component 320 by acting on the other end of the lever component 320.

[0051] Furthermore, to allow for a greater opening and closing range of the clamping assembly 300 and to facilitate the removal of the heat sink 600, in some embodiments of this application, such as... Figures 4 to 5 The clamping arm component 310 is provided with a first protrusion 311, and the lever component 320 is provided with a second protrusion 321. The lever component 320 is used to drive the first protrusion 311 to move through the second protrusion 321 when opening, so that the clamping arm component 310 opens relative to the lever component 320.

[0052] Understandably, the lever component 320 can open and unlock the mounting component 200 when subjected to external force. The first protrusion 311 and the second protrusion 321 allow the external force to be transmitted to the clamping arm component 310 via the lever component 320. The clamping arm component 310 is driven to move synchronously with the lever component 320 and can move relatively closer or further away, thereby increasing the opening and closing range of the clamping assembly 300 and making it easier to remove the radiator 600.

[0053] In some embodiments, when the lever component 320 swings around the hinge, it synchronously drives the first protrusion 311 to swing. The second protrusion 321 is disposed on the swing path of the first protrusion 311, so that the first protrusion 311 abuts against the second protrusion 321 and drives the second protrusion 321 to move. This causes the lever component 320 and the clamping arm component 310 to move away from each other simultaneously, thereby allowing the clamping arm component 310 and the lever component 320 to fully unfold, making it easier to remove the radiator 600. In some embodiments, the first protrusion 311 and the second protrusion 321 are always abutting and engaged, making the transmission more stable.

[0054] Furthermore, to improve the clamping effect of the clamping assembly 300 on the clamping mounting part 200, in some embodiments of this application, such as... Figures 4 to 5 The clamping arm component 310 has a first recess 331, and the lever component 320 has a second recess 332. When the clamping assembly 300 is in the closed position, the first recess 331 and the second recess 332 can cooperate to form a mounting hole 330, which is used for the mounting component 200 to pass through.

[0055] It is understandable that the first recess 331 and the second recess 332 will form a mounting hole 330 when the clamping assembly 300 is in the closed position. The mounting hole 330 can accommodate and limit the mounting part 200, so that the mounting part 200 can pass through the mounting hole 330 and be fixed to the motherboard 700 or the heat sink 600 during installation. After the mounting part 200 is fixed, the mounting part 200 is located in the mounting hole 330, and based on the clamping effect of the clamping assembly 300, the inner walls of the first recess 331 and the second recess 332 can reliably clamp the mounting part 200, thereby improving the clamping effect.

[0056] In some embodiments, the mounting member 200 is a screw, the end of which abuts against the end of the mounting hole 330. The end of the screw is used for fixed connection. The first recess 331 and the second recess 332 are complementary semi-circular holes, and the inner wall of the mounting hole 330 formed by the fit can be used to hold and fix the screw. In other embodiments, the mounting member 200 can also be a guide post, structural member, etc., and a corresponding connecting structure is provided on the motherboard 700 or heat sink 600 to be fixed to cooperate with the mounting member 200, which can also achieve the disassembly and assembly effect described in this application.

[0057] To facilitate easier passage of the mounting component 200 through the mounting hole 330 during installation, and to simultaneously open the clamping assembly 300 during passage, thereby improving the efficiency of assembly and disassembly, in some embodiments of this application, such as... Figures 4 to 5 Chamfers are formed on the ends of the first recess 331 and the second recess 332 respectively, so that the end of the mounting hole 330 formed by the first recess 331 and the second recess 332 has a guide bevel structure 333.

[0058] Understandably, when the mounting component 200 is installed under the guidance of the guide angle structure 333, it can push open the clamping arm component 310 and the lever component 320, so that the mounting component 200 can pass smoothly through the mounting hole 330 and be installed and fixed. After the mounting component 200 passes through the mounting hole 330, the clamping arm component 310 and the lever component 320 are clamped under the action of the elastic component 400, thereby improving the efficiency of disassembly and assembly through the guide angle structure 333.

[0059] It should be understood that, in actual use, the clamping assembly 300 is in its initial position. The mounting member 200, guided by the guide angled structure 333 at the end of the mounting hole 330, extends into the mounting hole 330 and is installed and fixed to the motherboard 700. At this time, the clamping assembly 300 is pushed open by the mounting member 200 and simultaneously subjected to the force of the elastic member 400, thereby switching from the initial position to the closed position, achieving the effect of closing and clamping the mounting member 200, thus completing the installation of the heat sink 600. When it is necessary to remove the heat sink 600, the clamping assembly 300 is opened to switch from the closed position to the open position. Then, the fixing device of this application is removed, and the mounting member 200 is moved away from the opening and closing part of the clamping assembly 300. At this time, subjected to the force of the elastic member 400, the clamping assembly 300 switches from the open position back to the initial position, so that the heat sink 600 can be installed and removed again through the fixing device of this application.

[0060] In some embodiments of this application, the elastic member 400 is a torsion spring; it is understood that the clamping assembly 300 opens and closes by swinging about the hinge, and the elastic member 400 is set as a torsion spring to provide torque so that the clamping assembly 300 has better reset and holding effect.

[0061] In one specific embodiment, the elastic component 400 is a torsion spring, and torsion springs are respectively provided at the hinge of the clamping arm component 310 and the hinge of the lever component 320.

[0062] In some embodiments of this application, reference is made to Figure 3 , Figure 4 and Figure 5 The base assembly 100 includes a cover plate 110 and a bottom cover 120. The bottom cover 120 and the cover plate 110 are connected by snap-fit ​​and form a mounting cavity. The clamping assembly 300 and the elastic component 400 are disposed within the mounting cavity. It is understood that the base assembly 100 serves to fix the entire mechanism. Before installation, the bottom cover 120 and the cover plate 110 are separate structures. Each component is installed sequentially and then connected by the snap-fit ​​structure to form a whole, thus facilitating the installation of the fixing device of this application.

[0063] In some embodiments of this application, reference is made to Figures 1 to 2The mounting base 500 and the base assembly 100 are respectively located at both ends of the length direction of the heat sink 600. The mounting base 500 is provided with a hook structure 510, and the heat sink 600 is provided with a slot 610. The mounting base 500 limits the heat sink 600 by hooking the hook structure 510 into the slot 610.

[0064] Understandably, by fixing the heatsink 600 to both ends using the mounting bracket 500 and the base assembly 100 respectively, the fixation effect of the heatsink 600 is improved. Simultaneously, since the mounting bracket 500 and the base assembly 100 are located at opposite ends of the length of the heatsink 600, their assembly and disassembly are less likely to interfere with each other, improving ease of assembly and disassembly. Furthermore, the mounting bracket 500 limits the heatsink 600 by engaging the hook structure 510 into the slot 610, allowing the clamping assembly 300 to clamp the mounting piece 200, thus completing the fixation of the heatsink 600.

[0065] In some embodiments, reference is made to Figure 1 The mounting base 500 limits the position of the heat sink 600 by engaging the hook structure 510 into the slot 610. At this time, the heat sink 600 can be removed from the mounting base 500 without being restricted when it moves away from the mounting base 500 along the length direction of the heat sink 600. Therefore, based on the hook structure 510 engaging the slot 610, the clamping component 300 clamps the mounting part 200 and limits the displacement direction, thus achieving the fixing effect of the heat sink 600.

[0066] The fixing device of this application embodiment is described in detail below with reference to a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0067] See Figures 1 to 5 As shown, the fixing device in this embodiment includes a mounting base 500, a base assembly 100, a mounting component 200, a clamping assembly 300, and a spring component 400. The mounting base 500 clamps one end of the heat sink 600 through the hook structure 510 of the outer shell. The other end of the heat sink 600 is fixed by the clamping assembly 300 cooperating with the mounting component 200. The heat sink 600 is locked onto the motherboard 700 by rotating and clamping the clamping arm component 310 and the lever component 320 under the action of the spring.

[0068] Specifically, the bottom cover 120 and the cover plate 110 are connected by a snap-fit ​​structure, which serves to fix the entire mechanism. The stud in the bottom cover 120 acts as a pivot and is used to install the clamping arm component 310 and the lever component 320. The clamping arm component 310 and the lever component 320 perform a clamping function, and the spring also serves to clamp the clamping arm component 310 and the lever component 320. When in use, the mounting member 200 pushes open the clamping arm component 310 and the lever component 320 under the guidance of the guide angle. After the mounting member 200 passes through the mounting hole 330 formed by the clamping arm component 310 and the lever component 320, the clamping arm component 310 and the lever component 320 close and clamp the mounting member 200 under the action of the spring, which, together with the mounting base 500, fixes the radiator 600. When unlocking is required, the lever component 320 is moved, and the clamping arm component 310 is pushed open under the action of the first protrusion 311 and the second protrusion 321, so that the clamping arm component 310 and the lever component 320 are opened, the mounting piece 200 is released and the radiator 600 is unlocked, and the radiator 600 can be removed from the mounting base 500, so as to achieve the purpose of quick disassembly and assembly.

[0071] See Figures 1 to 3 As shown, in some embodiments, the mounting base 500 is disposed on the motherboard 700 and used to fix one end of the heat sink 600 in the length direction, the base assembly 100 is disposed on the other end of the heat sink 600 in the length direction, and the mounting member 200 is disposed on the motherboard 700 and used to cooperate with the clamping assembly 300 on the base assembly 100, thereby realizing the quick assembly and disassembly of the heat sink 600.

[0072] Specifically, the mounting base 500 is soldered onto the motherboard 700, the studs are locked onto the motherboard 700, one end of the heatsink 600 is connected to the mounting base 500 via a hook, and the other end of the heatsink 600 is provided with a base assembly 100. The studs are clamped by the clamping assembly 300 on the base assembly 100 to achieve the purpose of fixing the heatsink 600.

[0073] The electronic product of the fourth aspect of this application may be a computer, smart home device, vehicle or automated device, etc. The electronic product includes: a motherboard 700, a heat sink 600 and a fixing device of the first aspect of this application. The fixing device is disposed on the motherboard 700 and is used to fix the heat sink 600.

[0074] It is easy to understand that the heat sink in the second aspect embodiment of this application, the motherboard in the third aspect embodiment of this application, and the electronic product in the fourth aspect embodiment of this application all have the same technical effects as the fixing device in the first aspect embodiment, and therefore will not be described again.
