An assembly structure for a computer cooling fan base

Abstract

This utility model discloses an assembly structure for a computer cooling fan base, relating to the field of assembly structure technology. It includes a base with two sets of symmetrically arranged ventilation holes on its rear surface. The cooling fan drives a slot to slide into a connecting frame, aligning a positioning post with a positioning groove. A spring's restoring force then drives the positioning post to slide back into the groove, penetrating the groove. This allows for quick installation of the cooling fan onto the ventilation holes. By sliding the positioning post into the groove and then sliding the cooling fan out of the connecting frame, quick disassembly of the cooling fan is achieved. This facilitates rapid assembly and disassembly of the cooling fan, allowing for separate storage of the ventilation holes and the cooling fan, reducing the difficulty of assembly and disassembly, and improving the efficiency of the worker's work.

Description

Technical Field

[0001] This utility model relates to the field of assembly structure technology, specifically to an assembly structure for a computer cooling fan base. Background Technology

[0002] With the rapid development of electronic information technology, computer performance is constantly improving, and the heat generated by its internal components during operation is also increasing. Efficient heat dissipation is crucial for ensuring stable computer operation and extending its lifespan, and the cooling fan base, as a key component of the heat dissipation system, directly affects the heat dissipation effect and overall stability through its assembly structure.

[0003] Currently, the common assembly structures for computer cooling fan bases include screw fixing, snap-fit ​​connections, magnetic assembly, and embedded assembly. Magnetic assembly uses magnetic components on the base and fan to achieve quick installation using magnetic force. However, the magnetic strength is limited, and under the vibration generated by the high-speed fan, the fan is prone to misalignment, leading to turbulent airflow. Embedded assembly enhances connection stability by embedding the fan into the groove of the base. However, this method requires extremely high machining precision, and even slight dimensional errors can cause assembly difficulties and hinder quick disassembly and replacement, thus requiring improvement.

[0004] The purpose of this utility model is to provide an assembly structure for a computer cooling fan base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an assembly structure for a computer cooling fan base, comprising a base, two sets of heat dissipation holes symmetrically opened on the rear surface of the base, connecting components being provided on the outer walls of the two sets of heat dissipation holes, a cooling fan being provided between the heat dissipation holes and the connecting components, the heat dissipation holes and the cooling fan forming a detachable design through the connecting components, and a clamping component for fixing the computer being provided on the front surface of the base.

[0006] As a further preferred embodiment of this technical solution, the connecting assembly includes two sets of connecting frames disposed on the outer wall of the base around the two sets of heat dissipation holes. The connecting frames are fixedly connected to the outer wall of the base. Each of the two sets of connecting frames has four sets of slots. Each of the four sets of slots has a plug slidably connected to a plug block. Each of the four sets of plug blocks has a cooling fan fixedly connected to its outer surface. Each of the four sets of horizontally arranged positioning posts has a sliding groove on the outer wall of the side opposite to the cooling fan. Each of the four sets of sliding grooves has a spring fixedly connected to its inner wall. Each of the four sets of springs has a positioning post fixedly connected to its other end, and the positioning post slides within the sliding groove. Each of the four sets of positioning posts has a positioning groove on the inner wall of the connecting frame corresponding to its outer surface.

[0008] As a further preferred embodiment of this technical solution, one end of the spring is welded to the middle position of the inner wall of the slide groove, and the other end of the spring is welded to the middle position of the inner wall of the positioning column.

[0009] As a further preferred embodiment of this technical solution, the clamping assembly includes a baffle plate disposed on the front surface of the base below the heat dissipation hole. A bidirectional lead screw is rotatably connected inside the baffle plate. Two sets of transmission blocks are threadedly connected to the bidirectional lead screw.

[0011] This utility model provides an assembly structure for a computer cooling fan base, which has the following features:

[0012] Beneficial effects:

[0013] 1. This utility model uses a cooling fan to drive the slot into the connecting frame, aligning the positioning post with the positioning groove. Then, the spring's restoring force drives the positioning post to slide back in the groove, allowing it to pass through the groove. This achieves the purpose of quickly installing the cooling fan onto the heat dissipation hole. By sliding the positioning post into the groove and then sliding the cooling fan out of the connecting frame, the cooling fan can be quickly disassembled. This facilitates quick assembly and disassembly of the cooling fan by workers, allowing the heat dissipation hole and cooling fan to be stored separately. It also reduces the difficulty of assembling and disassembling the cooling fan, thereby improving the work efficiency of workers in disassembling and disassembling the cooling fan.

[0014] 2. This utility model uses a brake disc to drive a bidirectional lead screw to rotate within a baffle, and the bidirectional lead screw simultaneously acts on two sets of clamping plates, causing the two sets of clamping plates to converge towards the center of the heat dissipation hole until the two sets of clamping plates clamp the computer onto the heat dissipation hole, allowing the heat dissipation hole and cooling fan to cool the computer. At this time, by rotating the threaded rod inside the brake disc, the threaded rod is rotated into a corresponding set of threaded grooves, thereby achieving the purpose of clamping computers of different sizes, enabling the computer to be used stably on the base, and allowing the heat dissipation hole to cool the computer.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, an assembly structure for a computer cooling fan base includes a base 1. Two sets of heat dissipation holes 2 are symmetrically opened on the rear surface of the base 1. Connecting components 4 are provided on the outer walls of the two sets of heat dissipation holes 2. A cooling fan 3 is provided between the heat dissipation holes 2 and the connecting components 4. The heat dissipation holes 2 and the cooling fan 3 form a detachable design through the connecting components 4. A clamping component 5 for fixing the computer is provided on the front surface of the base 1.

[0022] like Figure 2 and Figure 4 As shown, the connecting component 4 includes two sets of connecting frames 41 disposed on the outer wall of the base 1 around the two sets of heat dissipation holes 2. The connecting frames 41 are fixedly connected to the outer wall of the base 1. Each of the two sets of connecting frames 41 has four sets of slots 42. Each of the four sets of slots 42 has a plug 43 slidably connected in it. Each of the four sets of plugs 43 has a cooling fan 3 fixedly connected to its outer surface. Each of the four sets of positioning posts 46 arranged horizontally has a sliding groove 44 on the outer wall of the side opposite to the cooling fan 3. Each of the four sets of sliding grooves 44 has a spring 45 fixedly connected to its inner wall. Each of the four sets of springs 45 has a positioning post 46 fixedly connected to its other end. The positioning posts 46 slide in the sliding grooves 44. Each of the four sets of positioning posts 46 has a positioning groove 47 on the inner wall of the connecting frame 41 corresponding to its outer surface.

[0023] The cooling fan 3 drives the slot 42 to slide into the connecting frame 41, aligning the positioning post 46 with the positioning groove 47. Then, the restoring force of the spring 45 drives the positioning post 46 to slide back in the slide groove 44, allowing the positioning post 46 to pass through the positioning groove 47. This achieves the purpose of quickly installing the cooling fan 3 onto the heat dissipation hole 2. By sliding the positioning post 46 into the slide groove 44 and then sliding the cooling fan 3 out of the connecting frame 41, the cooling fan 3 can be quickly disassembled. This facilitates the quick assembly and disassembly of the cooling fan 3 by the staff, allowing the heat dissipation hole 2 and the cooling fan 3 to be stored separately. It also reduces the difficulty of assembling and disassembling the cooling fan 3, thereby improving the work efficiency of the staff in disassembling the cooling fan 3.

[0024] like Figure 2 and Figure 4 As shown, the outer surface of the positioning post 46 is semi-circular and has been polished. When the outer wall of the positioning post 46 slides into the positioning groove 47, the cooling fan 3 is pulled, causing the cooling fan 3 to push the positioning post 46 against the positioning groove 47 through the slot 42. Under the pressure of the positioning groove 47, the positioning post 46 automatically slides into the slide groove 44, thereby achieving the purpose of quick disassembly of the cooling fan 3. At the same time, when the operator presses the positioning post 46 into the slide groove 44, it can also increase the friction between the operator's hand and the positioning post 46, preventing the need to repeatedly operate the positioning post 46 due to slippage.

[0025] like Figure 2 and Figure 4 As shown, one end of the spring 45 is welded to the middle position of the inner wall of the slide groove 44, and the other end of the spring 45 is welded to the middle position of the inner wall of the positioning post 46. This allows the force generated by the spring 45 when it is squeezed by the positioning post 46 to be evenly output to the positioning post 46, so that the positioning post 46 can slide smoothly in the slide groove 44 and pass through the positioning groove 47, thereby improving the stability of the spring 45 during use.

[0026] like Figure 1 and Figure 3 As shown, the clamping assembly 5 includes a baffle 51 disposed on the front surface of the base 1 below the heat dissipation hole 2. A bidirectional lead screw 52 is rotatably connected inside the baffle 51. Two sets of transmission blocks 53 are threadedly connected to the bidirectional lead screw 52. A clamping plate 54 is fixedly connected to the end surface of the two sets of transmission blocks 53 facing the heat dissipation hole 2. A brake disc 55 is fixedly connected to the left end surface of the bidirectional lead screw 52. A threaded rod 56 is threadedly connected inside the brake disc 55. Multiple sets of threaded grooves 57 are opened on the outer wall of the baffle 51 corresponding to the inner end surface of the threaded rod 56.

[0027] The brake disc 55 drives the bidirectional lead screw 52 to rotate within the baffle 51, and the bidirectional lead screw 52 simultaneously acts on the two sets of clamping plates 54, causing the two sets of clamping plates 54 to converge towards the center of the heat dissipation hole 2 until the two sets of clamping plates 54 clamp the computer onto the heat dissipation hole 2, so that the heat dissipation hole 2 and the cooling fan 3 can dissipate heat from the computer. At this time, the threaded rod 56 is rotated within the brake disc 55, so that the threaded rod 56 rotates into the corresponding set of threaded grooves 57, thereby achieving the purpose of clamping computers of different sizes, so that the computer can be used stably on the base 1, and the heat dissipation hole 2 can dissipate heat from the computer.

[0028] like Figure 1 and Figure 3 As shown, ten sets of threaded grooves 57 are equally spaced. The outer surface of the threaded grooves 57 is pentagonal. When the brake disc 55 drives the threaded rod 56 to rotate to align with any threaded groove 57, the threaded rod 56 is rotated into the threaded groove 57 by rotating the threaded rod 56 inside the brake disc 55, thereby achieving the purpose of limiting the rotation of the brake disc 55 and enabling the clamping plate 54 to stably clamp the computer on the base 1 for use.

[0029] This utility model provides an assembly structure for a computer cooling fan base. The specific working principle is as follows: First, the positioning post 46 is pressed into the slide groove 44, and the positioning post 46 continuously compresses the spring 45. Then, the cooling fan 3 drives the slot 42 to slide into the connecting frame 41, and the positioning post 46 is aligned with the positioning groove 47. Then, the restoring force of the spring 45 pushes the positioning post 46 to reset and slide within the slide groove 44, and the positioning post 46 passes through the positioning groove 47, thereby fixing the cooling fan 3 in the position directly opposite the heat dissipation hole 2. When it is necessary to disassemble the cooling fan 3, simply slide the positioning post 46 into the slide groove 44, and then the cooling fan 3 drives the slot 42 to slide out from the connecting frame 41.
