Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, specifically relating to a splicing and fixing cooling fan module. Background Technology

[0002] A cooling fan module is an integrated heat dissipation solution, mainly composed of a fan, heat sink fins, heat pipes (optional), and a housing. It dissipates the heat generated by electronic devices (such as computer CPUs, GPUs, servers, and industrial equipment) into the surrounding environment through forced convection or natural convection, ensuring that the devices operate within a safe temperature range.

[0003] In traditional technology, to increase the heat dissipation area, multiple cooling fans are connected together. A hinge is installed on top of the cooling fan, and screws are used to fix the hinge and the fan together to complete the splicing of two sets of cooling fans and achieve greater airflow. However, when disassembling, auxiliary tools are needed to remove the bolts, and repeated removal of the bolts can cause stripping of the Phillips head or hex head. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a splicing and fixing cooling fan module, which solves the problems of complex operation and slow speed when splicing two sets of fan modules under existing technologies.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a splicing and fixing cooling fan module. The fan module includes a cooling fan, a protective frame is rotatably connected to the outside of the cooling fan, a protective cover is fixedly connected to the front of the protective frame, a receiving groove is opened in the middle of the right side of the protective frame, a fixing frame is fixedly connected inside the receiving groove, a square hole is opened on the surface of the fixing frame, a pad is fixedly connected to the middle of the left side of the protective frame, and an insert is fixedly connected to the outside of the pad at a position corresponding to the square hole. There are two sets of inserts, and a slot is opened on the side of the two sets of inserts that are close to each other.

[0008] When using the fan module of this technical solution, the extrusion plate is rotated by the rotating shaft, so that the maximum surface of the extrusion plate releases the pressure on the limit rod, allowing the limit rod to slide inside the baffle. Then, the extrusion plate is moved closer to the partition, and the insert is inserted into the square hole. After releasing the handle, the extension and retraction of the second spring will reset the slide rod. Finally, the extrusion plates move away from each other, and the protrusion will be inserted into the slot to fix the insert.

[0009] Preferably, the fixed frame has a placement slot inside, and partitions are symmetrically fixedly connected inside the placement slot. A baffle is fixedly connected between the two sets of partitions. A limit rod is slidably connected inside the baffle. A locking seat is fixedly connected to the end of the limit rod away from the baffle. Two sets of guide rods are rotatably connected inside the locking seat.

[0010] Furthermore, a swing rod is rotatably connected to the end of the guide rod away from the card seat. A groove is provided inside the partition, through which the swing rod slides and is connected to the partition. A pressing plate is fixedly connected to the end of the swing rod away from the guide rod, and a protrusion is provided on the outside of the pressing plate at a position corresponding to the card slot.

[0011] Furthermore, a rotating shaft is rotatably connected inside the placement slot and on the side of the baffle away from the limit rod. The rotating shaft extends to the outside of the protective frame and is rotatably connected to the protective frame. A handle is fixedly connected to the top of the rotating shaft.

[0012] Furthermore, an extrusion disc is fixedly connected to the outside of the rotating shaft, and the rotating shaft is fixedly connected to the eccentric part of the extrusion disc. A first spring is sleeved on the outside of the limiting rod and at the end of the baffle away from the rotating shaft. The limiting rod passes through the baffle and contacts the extrusion disc.

[0013] Furthermore, a fixed seat is rotatably connected to the bottom end of the rotating shaft. The fixed seat is fixedly connected to the inner wall of the placement groove. A slide rod is slidably connected inside the fixed seat. A second spring is sleeved on the outside of the slide rod. A contact plate is fixedly connected to one end of the slide rod. An extrusion block is fixedly connected to the bottom end of the rotating shaft at a position corresponding to the contact plate.

[0014] Furthermore, a fixing plate is fixedly connected to the outside of the protective frame and the outside of the receiving groove. Hooks are symmetrically fixedly connected to the outside of the fixing plate. The hooks have a beveled structure design. A fixing block is fixedly connected to the middle of the fixing plate. An insertion groove is opened on the right side of the protective frame at the position corresponding to the hook. A fitting groove is opened between the two sets of insertion grooves at the position corresponding to the fixing block.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The fan module of this utility model uses a pressing plate design. The pressing plate is rotated by a rotating shaft, which releases the pressure on the limiting rod at the maximum surface of the pressing plate, allowing the limiting rod to slide inside the baffle. Then, the pressing plate moves towards the partition in sync, and the insert is inserted into the square hole. After releasing the handle, the extension and retraction of the second spring will reset the sliding rod. Finally, the pressing plates move away from each other, and the protrusion will be inserted into the slot to fix the insert.

[0018] The fan module of this utility model uses a hook design to directly enter the interior of the insertion slot, while the fixing block enters the interior of the fitting slot. After the hook's inclined surface contacts the insertion slot, a component force is generated along the hook direction, thereby maintaining a taut state and preventing the two sets of cooling fans from shaking after being spliced ​​together.

[0026] This specific embodiment is a splicing and fixing cooling fan module, the structural diagram of which is shown below. Figure 1-6As shown, the fan module includes a cooling fan 1, a protective frame 2 rotatably connected to the outside of the cooling fan 1, a protective cover 3 fixedly connected to the front of the protective frame 2, a receiving groove 4 opened in the middle of the right side of the protective frame 2, a fixed frame 5 fixedly connected inside the receiving groove 4, a square hole 6 opened on the surface of the fixed frame 5, a pad fixedly connected in the middle of the left side of the protective frame 2, and an insert 7 fixedly connected at the position corresponding to the square hole 6 on the outside of the pad. There are two sets of insert 7, and a slot 8 is opened on the side of the two sets of insert 7 that are close to each other. The protective frame 2 effectively prevents the cooling fan 1 from contacting the outside. At the same time, the design of the protective cover 3 prevents foreign objects from entering the interior of the protective frame 2 and contacting the cooling fan 1, which could damage the internal components. When it is necessary to connect two sets of cooling fans 1, the insert 7 is inserted into the interior of the square hole 6, and then the insert 7 will directly extend into the interior of the fixed frame 5, so that the two sets of cooling fans 1 fit together and complete the splicing.

[0027] In this embodiment, the fixed frame 5 has a placement groove inside, and partitions 9 are symmetrically fixedly connected inside the placement groove. A baffle 10 is fixedly connected between the two sets of partitions 9. A limit rod 11 is slidably connected inside the baffle 10. A snap-fit ​​seat 12 is fixedly connected to the end of the limit rod 11 away from the baffle 10. Two sets of guide rods 13 are rotatably connected inside the snap-fit ​​seat 12. By pulling the limit rod 11 inside the baffle 10, and then sliding the limit rod 11, the snap-fit ​​seat 12 is driven to move synchronously and generate a pulling force on the guide rod 13, so that the guide rod 13 swings to an inclined state inside the snap-fit ​​seat 12.

[0028] Secondly, in this embodiment, a swing rod 14 is rotatably connected to the end of the guide rod 13 away from the card seat 12. A sliding groove is provided inside the partition 9. The swing rod 14 passes through the sliding groove and is slidably connected to the partition 9. A pressing plate 15 is fixedly connected to the end of the swing rod 14 away from the guide rod 13. A protrusion is provided on the outside of the pressing plate 15 at the position corresponding to the card slot 8. As the guide rod 13 tilts, it will generate a pulling force on the swing rod 14, so that the swing rod 14 slides inside the partition 9. Then, it synchronously drives the pressing plate 15 to move closer to the partition 9.

[0029] Furthermore, in this embodiment, a rotating shaft 16 is rotatably connected inside the placement slot and on the side of the baffle 10 away from the limiting rod 11. The rotating shaft 16 extends to the outside of the protective frame 2 and is rotatably connected to the protective frame 2. A handle 17 is fixedly connected to the top of the rotating shaft 16, and an extrusion disc 18 is fixedly connected to the outside of the rotating shaft 16. The rotating shaft 16 and the extrusion disc 18 are fixedly connected at an eccentric point. A first spring 19 is sleeved on the outside of the limiting rod 11 and at the end of the baffle 10 away from the rotating shaft 16. The limiting rod 11 passes through the baffle 10 and contacts the extrusion disc 18. By gripping the handle... 17 rotates, which in turn drives the rotating shaft 16 to rotate. Since the rotating shaft 16 is eccentric at the extrusion plate 18, the maximum surface of the extrusion plate 18 releases the pressure on the limiting rod 11. Then, through the extension and retraction of the first spring 19, the limiting rod 11 slides inside the baffle 10. Then, the insert 7 is inserted into the square hole 6, and the extrusion plate 18 is limited. Then, the first spring 19 drives the limiting rod 11 to reset. Finally, the extrusion plates 15 move away from each other, and the protrusion is inserted into the slot 8 to fix the insert 7.

[0030] Furthermore, in this embodiment, a fixed seat 20 is rotatably connected to the bottom end of the rotating shaft 16. The fixed seat 20 is fixedly connected to the inner wall of the placement groove. A sliding rod is slidably connected inside the fixed seat 20. A second spring 21 is sleeved on the outside of the sliding rod. A contact plate 22 is fixedly connected to one end of the sliding rod. A pressing block 23 is fixedly connected to the bottom end of the rotating shaft 16 at a position corresponding to the contact plate 22. When the rotating shaft 16 is rotated, the pressing block 23 will rotate synchronously with the rotating shaft 16 and press the contact plate 22. Then the sliding rod will slide inside the fixed seat 20 and compress the second spring 21, which will drive the pressing disc 18 to rotate. Then the handle 17 is released, and the extension and retraction of the second spring 21 will reset the sliding rod. Then the contact plate 22 will press the pressing block 23, which will reset the rotating shaft 16 and ensure that the pressing disc 18 always presses the limiting rod 11.

[0031] Furthermore, in this embodiment, a fixing plate is fixedly connected to the outside of the protective frame 2 and to the outside of the receiving groove 4. Hooks 24 are symmetrically fixedly connected to the outside of the fixing plate. The hooks 24 have a beveled structure design. A fixing block 25 is fixedly connected to the middle of the fixing plate. A insertion groove 26 is provided on the right side of the protective frame 2 at the position corresponding to the hooks 24. A fitting groove 27 is provided between the two sets of insertion grooves 26 and at the position corresponding to the fixing block 25. After the insert 7 is inserted into the square hole 6, the hooks 24 directly enter the interior of the insertion grooves 26. At the same time, the fixing block 25 enters the interior of the fitting groove 27. After the beveled surface of the hooks 24 contacts the insertion grooves 26, a component force is generated along the direction of the hooks 24, thereby maintaining a taut state and preventing the two sets of cooling fans 1 from shaking after being spliced.

[0032] When using the device of this technical solution, the protective frame 2 is fitted over the outside of the cooling fan 1 to effectively prevent the cooling fan 1 from contacting the outside. Simultaneously, the design of the protective cover 3 prevents foreign objects from entering the interior of the protective frame 2 and contacting the cooling fan 1, which could damage internal components. When connecting two sets of cooling fans 1, the pressing block 23 rotates synchronously with the rotating shaft 16 after the shaft 16 is rotated, pressing the contact plate 22. Subsequently, the sliding rod slides inside the fixed seat 20, compressing the second spring 21, which in turn drives the pressing disc 18 to rotate. Because the rotating shaft 16 is eccentrically positioned on the pressing disc 18, the maximum surface of the pressing disc 18 releases the pressure on the limiting rod 11. Then, through the extension and retraction of the first spring 19, the limiting rod 11 slides inside the baffle 10, causing the locking seat 12 to move synchronously and generating tension on the guide rod 13. This causes the guide rod 13 to swing to an inclined position inside the locking seat 12, generating tension on the swing rod 14. The swing arm 14 slides inside the partition 9, and then simultaneously drives the extrusion plate 15 to move closer to the partition 9. Then, the insert 7 is inserted into the square hole 6. After releasing the handle 17, the extension and retraction of the second spring 21 will reset the slide arm. Then, the contact plate 22 will press the extrusion block 23, and the rotating shaft 16 will be reset. The extrusion plate 18 will always press the limit rod 11. Then, the first spring 19 will drive the limit rod 11 to reset. Finally, the extrusion plates 15 will move away from each other, and the protrusion will be inserted into the slot 8 to fix the insert 7. The hook 24 will directly enter the insertion slot 26, and the fixing block 25 will enter the fitting slot 27. After the hook 24 contacts the insertion slot 26 through the inclined surface, a component force along the hook 24 will be generated to keep it taut and prevent the two sets of cooling fans 1 from shaking after splicing. Compared with the existing fan modules, this utility model can improve the overall practicality of the fan module through design.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
