Abstract
Description
Technical Field
[0001] This utility model relates to the field of computer cases, and in particular to a case fan mounting bracket. Background Technology
[0002] Currently, the fans of home computer hosts are usually screwed onto the mounting posts on the chassis. This means that each fan requires four mounting posts, which are pre-installed on the computer host chassis. However, different consumers have different computer usage habits. For example, gaming hosts need more fans, while office hosts may not need as many. This leads to a situation where sometimes the pre-installed mounting posts on the computer chassis are insufficient, while at other times they are left unused. In addition, each fan requires four screws to be tightened to secure it, which is time-consuming and laborious during installation.
[0003] Chinese patent document CN217421651U discloses a screwless fan bracket for use in computer cases. The case includes a U-shaped base, and the screwless fan bracket includes a heat dissipation assembly and two limiting mechanisms. The two limiting mechanisms are respectively installed on the inner side wall of the U-shaped base and are arranged opposite to each other. The heat dissipation assembly is engaged with the two limiting mechanisms. Each limiting mechanism includes a mounting base, a connecting post, and a limiting post. The mounting base includes a first side plate and a second side plate, which are L-shaped. The first side plate is installed on the inner side wall of the U-shaped base. The engagement between the limiting post and the mounting hole achieves initial positioning of the frame, and then the engagement between the slot and the connecting post allows the fan bracket to be installed on the U-shaped base. This screwless fan bracket solves the problem in the prior art that multiple screws are needed for fixing the fan bracket, making the installation and removal of the fan bracket cumbersome and preventing easy replacement of the fan.

[0015] A further technical solution of this utility model is that the second type of snap-fit component includes a limiting baffle and at least one snap-fit spring, wherein the limiting baffle is located on one side of the mounting position, and at least one snap-fit spring is located on the other side of the mounting position.
[0016] A further technical solution of this utility model is that a reinforcing rib is provided between the two connected snap-fit spring pieces.
[0017] A further technical solution of this utility model is that it also includes at least one positioning post for matching the screw hole on the computer fan, and at least one of the positioning posts is fixed to the front of the main frame.
[0018] A further technical solution of this utility model is that the main frame includes a rectangular frame and at least one reinforcing connecting plate, and the end of each reinforcing connecting plate is connected to the two sides of the rectangular frame.

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] Example 1
[0036] like Figures 1 to 6As shown, the chassis fan mounting bracket provided in this embodiment includes a main frame 1. The front of the main frame 1 has at least one mounting position 11 for engaging with a computer fan 2. The shape of the mounting position 11 matches the shape of the computer fan 2. The computer fan 2 typically includes a motor, a fan, and a square outer frame 21. The shape of the mounting position 11 matches the shape of the outer frame of the computer fan 2. The back of the main frame 1 has a first type of snap-fit member 3 for engaging with the side wall of the chassis. The chassis fan mounting bracket can be snapped onto the chassis using the first type of snap-fit member 3. On the side wall of the case, at least one second-type snap-fit piece 4 is provided at the edge of the mounting position 11. The computer fan 2 is snapped onto the mounting position 11 through at least one second-type snap-fit piece 4, thereby indirectly mounting the computer fan 2 onto the side wall of the case. The number of computer fans 2 that can be snapped onto the main frame 1 can be determined by the number of mounting positions 11 provided on the main frame 1. This makes this case fan mounting bracket particularly suitable for users' DIY needs. Users can quickly install and remove computer fans 2 according to their own needs to select the appropriate number of computer fans 2. In addition, both the first-type snap-fit piece 3 and the second-type snap-fit piece 4 adopt a snap-fit engagement, so that the above-mentioned case fan mounting bracket can not only achieve the snap-fit of multiple computer fans 2 to the main frame 1, but also achieve the snap-fit of the main frame 1 to the side wall of the case.
[0037] More preferably, the chassis fan mounting bracket provided in this embodiment includes two or more second-type snap-fit parts 4, and one or more first-type snap-fit parts 3 are fixed on the corresponding second-type snap-fit parts 4. In this way, the first-type snap-fit parts 3 can be integrally formed with the second-type snap-fit parts 4, which can effectively reduce material costs and shorten the processing time. Since the first-type snap-fit parts 3 are fixed on the second-type snap-fit parts 4, their number is usually less than the number of second-type snap-fit parts 4. At this time, the second-type snap-fit parts 4 can be divided into two categories, namely, combined snap-fit parts 71 and conventional snap-fit parts 72. The combined snap-fit parts 71 are second-type snap-fit parts 4 with first-type snap-fit parts 3 fixed on them, and the conventional snap-fit parts 71 are second-type snap-fit parts 4 without first-type snap-fit parts 3 fixed on them. That is, the combined snap-fit parts 71 are regarded as a new independent component, which is an integrally formed combination of first-type snap-fit parts 3 and second-type snap-fit parts 4. Specifically, the combined snap-fit component 71 includes a main spring 61 and a secondary spring 62. The main spring 61 has a receiving opening 611 in the middle. A part of the secondary spring 62 extends into the receiving opening 611 and is fixed on one edge of the receiving opening 611. The entire main spring 61 and the secondary spring 62 can be integrally formed. The main spring 61 can effectively snap into the computer fan 2 placed in the mounting position 11, while the secondary spring 62 extends to the lower surface of the main frame 1, thereby snapping into the limiting groove on the side wall of the chassis. More preferably, the main spring tab 61 is provided with a main locking protrusion 612, and the secondary spring tab 62 is provided with a secondary locking protrusion 621. The orientation of the main locking protrusion 612 is opposite to that of the secondary locking protrusion 621, and the orientation of the secondary locking protrusion 621 is opposite to that of the main locking protrusion 612. The main locking protrusion 612 faces the mounting position 11 to facilitate the computer fan 2, while the secondary locking protrusion 621 faces the opposite direction, away from the mounting position 11. Thus, when releasing the secondary locking protrusion 621, pressing the secondary spring tab 62 towards the side where the mounting position 11 is located allows the secondary locking protrusion 621 to disengage from the limiting groove on the side wall of the chassis, making installation very convenient. Figures 3 to 6As shown, the number of the first type of connector 3 and the second type of connector 4 can be reasonably selected according to the number of the main frame 1 and the computer fan 2. They are usually set in pairs. Preferably, in the case where the chassis fan mounting bracket provided in this embodiment has only one mounting position 11, four combined connectors 71 are usually symmetrically arranged at the four corners of the chassis fan mounting bracket to ensure that all four corners of the chassis fan mounting bracket can be connected to the side wall of the chassis. In the case where the chassis fan mounting bracket provided in this embodiment has only two mounting positions 11, four combined connectors 71 are still symmetrically arranged at the four corners of the chassis fan mounting bracket, and the chassis fan mounting bracket... Two standard-type snap-fit connectors 72 can be installed in the middle of the bracket, thereby reducing material costs and assembly / disassembly difficulty. In the case where the chassis fan mounting bracket provided in this embodiment has only three mounting positions 11, four combined snap-fit connectors 71 are symmetrically installed at the four corners of the chassis fan mounting bracket. However, considering that the chassis fan mounting bracket is already quite long, it is also possible to simultaneously install one or more combined snap-fit connectors 71 in the middle of the chassis fan mounting bracket, and the rest as standard-type snap-fit connectors 72. This ensures that the middle of the longer chassis fan mounting bracket can also be firmly fixed to the side wall of the chassis, ensuring the installation stability of multiple computer fans 2. For cases with more mounting positions 11, the number of combined snap-fit connectors 71 and standard-type snap-fit connectors 72 can be reasonably matched according to the above rules. Theoretically, any number of mounting positions 11 can meet the requirements; however, considering the size of the computer chassis, the number of mounting positions 11 is usually less than 10.
[0038] Example 2
[0039] like Figures 7 to 9 As shown, the chassis fan mounting bracket provided in this embodiment includes a main frame 1. The front of the main frame 1 has at least one mounting position 11 for engaging with a computer fan 2. The back of the main frame 1 has a first type of snap-fit member 3 for engaging with the side wall of the chassis. At least one second type of snap-fit member 4 is provided at the edge of the mounting position 11. The computer fan 2 is snapped onto the mounting position 11 via at least one second type of snap-fit member 4. The first type of snap-fit member is fixed to the second type of snap-fit member.
[0040] The difference between Example 2 and Example 1 is that:
[0041] To facilitate the installation of the main frame 1 on the side wall of the chassis by the first type of snap-fit component 3, the first type of snap-fit component 3 further includes at least one snap head 31 that is inserted into the first type of limiting groove on the chassis. At least one snap head 31 is fixed at one end of the main frame 1. Specifically, the snap head 31 is used for limiting one end of the main frame 1. The number of snap heads 31 can be one or more. Considering the balance of force, two snap heads 31 are generally provided, and the two snap heads 31 are symmetrically arranged at one end of the main frame 1. Furthermore, the first type of latching component 3 also includes at least one elastic latching component 32 that is inserted into the second type of limiting groove on the chassis. At least one elastic latching component 32 is fixed to the other end of the main frame 1. The elastic latching component 32 has a lever, namely the J-shaped latching plate 321 mentioned below. By moving the lever, the latching protrusion 322 can be disengaged from the latching position, thus unlocking the latching of the elastic latching component 32 and facilitating latching and disengaging. Similarly, the number of elastic latching components 32 can be one or more. Considering the balance of force, two elastic latching components 32 are generally provided, and the two elastic latching components 32 are symmetrically arranged at the other end of the main frame 1. More preferably, the elastic latching component 32 includes a J-shaped latching plate 321 and a latching protrusion 322. The latching protrusion 322 is fixed to the side wall of the J-shaped latching plate 321. By moving the J-shaped latching plate 321, the latching protrusion 322 can be disengaged from the latching position.
[0042] To facilitate the second type of snap-fit component 4 in fixing the computer fan 2 to the mounting position 11 of the main frame 1, the second type of snap-fit component 4 further includes at least one snap-fit spring 41. The snap-fit spring 41 can fix the outer frame 21 of the computer fan 2, thereby fixing the computer fan 2 to the mounting position 11 of the main frame 1. To ensure that the outer frame 21 is subjected to balanced force, the snap-fit springs 41 are usually arranged in pairs, symmetrically distributed on both sides of the outer frame 21, which can be diagonally distributed or symmetrically arranged. More preferably, the second type of snap-fit component 4 includes four snap-fit springs 41, which are symmetrically distributed at the four corners of the mounting position 11, thereby precisely locking the four corners of the outer frame 21, thus making the outer frame 21 more firmly fixed. More preferably, the end of the snap-fit spring 41 is provided with a snap-fit connector 411, which precisely locks onto the outer surface of the outer frame 21, thereby effectively preventing the outer frame 21 from detaching from the snap-fit position.
[0043] To position the outer frame 21 of the computer fan 2 during installation and prevent displacement, the chassis fan mounting bracket provided in this embodiment also includes at least one positioning post 5 adapted to the screw holes on the computer fan 2. At least one positioning post 5 is fixed to the front of the main frame 1, i.e., the front of the mounting position 11. Since the positioning post 5 is positioned exactly corresponding to the screw holes of the computer fan 2, when the computer fan 2 is placed in the mounting position 11, combined with the limiting effect of the four snap-fit springs 41, the computer fan 2 fits perfectly into the entire mounting position 11 without any shaking. The positioning post 5 can be one, a pair, three, or four; when in pairs, they are usually positioned diagonally.
[0044] Example 3
[0045] like Figure 10 As shown, the chassis fan mounting bracket provided in this embodiment includes a main frame 1. The front of the main frame 1 has at least one mounting position 11 for engaging with a computer fan 2. The back of the main frame 1 has a first-type snap-fit member 3 for engaging with the side wall of the chassis. At least one second-type snap-fit member 4 is provided at the edge of the mounting position 11. The computer fan 2 is snapped into the mounting position 11 by at least one second-type snap-fit member 4. The difference between Embodiment Two and Embodiment One is that:
[0046] To reinforce the structure of the snap-fit spring clip 41, a reinforcing rib 42 is provided between two connected snap-fit spring clips 41. The reinforcing rib 42 can connect two adjacent snap-fit spring clips 41 into one unit, avoiding the problem that a single snap-fit spring clip 41 is easy to break when subjected to impact force, and improving the stability of the snap-fit spring clip 41.
[0047] To further reinforce the structure of the main frame 1, preferably, the main frame 1 includes a rectangular frame 12 and at least one reinforcing connecting plate 13. The end of each reinforcing connecting plate 13 is connected to both sides of the rectangular frame 12, thereby making the main frame 1 more resistant to pressure from both sides and making the main frame 1 more robust. In addition, reinforcing end plates 14 can be provided at the two narrow ends of the main frame 1 to improve the structural strength of the narrow ends.
[0048] Example 4
[0049] like Figure 11 As shown, the chassis fan mounting bracket provided in this embodiment includes a main frame 1. The front of the main frame 1 has at least one mounting position 11 for engaging with a computer fan 2. The back of the main frame 1 has a first-type snap-fit member 3 for engaging with the side wall of the chassis. At least one second-type snap-fit member 4 is provided at the edge of the mounting position 11. The computer fan 2 is snapped into the mounting position 11 by at least one second-type snap-fit member 4. The difference between Embodiment Two and Embodiment One is that:
[0050] To facilitate the second type of snap-fit component 4 in fixing the computer fan 2 to the mounting position 11 of the main frame 1, the second type of snap-fit component 4 includes a limiting baffle 43 and at least one snap-fit spring 41. The limiting baffle 43 is located on one side of the mounting position 11, and at least one snap-fit spring 41 is located on the other side of the mounting position 11. That is, the limiting baffle 43 and at least one snap-fit spring 41 can also limit the outer frame 21 of the computer fan 2. In actual installation, one side of the computer fan 2 can be inserted into the gap below the limiting baffle 43, and the other side of the computer fan 2 is then fixed by the snap-fit spring 41.
