Description

Technical Field

[0001] This utility model relates to the field of computer fans, and in particular to a computer cooling fan with spliced ​​light. Background Technology

[0002] With the development of computer fans, users have increasingly higher requirements for the appearance and lighting effects of fans. Existing cooling fans generally use two-color injection molding to make the casing part transparent or semi-transparent. However, the cost of such molds is also relatively high, resulting in a higher unit price for such casings, which affects market competitiveness. In addition, these casings also have a high defect rate, and the plastic from defective products cannot be directly recycled. Although some fans use splicing, the light guiding span between the splicing structure and the casing is small (it can be understood that the splicing structure can only achieve local light guiding, such as the upper or lower casing), so the light diffusion effect is also poor. Utility Model Content

[0003] The main purpose of this invention is to propose a spliced ​​light-emitting computer cooling fan, which aims to improve the splicing structure, reduce the production cost of the fan housing while achieving better light guiding effect, and has a simple structure that is easy to assemble.

[0004] To achieve the above objectives, this utility model proposes a spliced ​​light-emitting computer cooling fan, including a rectangular frame, wherein the bottom wall and / or top wall of the rectangular frame are provided with positioning grooves, and the positioning grooves are adapted to the inner circumferential shape of the rectangular frame;

[0005] The positioning slot is detachably fitted with a positioning frame, and the positioning frame and / or rectangular frame are made of light-guiding material.

[0006] In the actual design, the fan housing is divided into two modules: a rectangular frame and a positioning frame. The positioning groove is directly formed in the rectangular frame. Therefore, during injection molding, it can be made of two different materials with different colors or light transmittance. When the fan is installed or installed in the position of RGB lights, the predetermined light illumination effect can be achieved. The combination of the two structures effectively reduces the production cost. At the same time, the positioning groove is set with a large span, which can not only achieve the structural stability of the fan housing, but also improve the light radiation range.

[0016] like Figures 1 to 5 As shown, a computer cooling fan with spliced ​​light includes a rectangular frame 1, the bottom wall and / or top wall of the rectangular frame 1 are provided with positioning grooves 10, and the positioning grooves 10 are adapted to the inner circumferential shape of the rectangular frame 1.

[0017] The positioning groove 10 is detachably fitted with a positioning frame 2, and the positioning frame 2 and / or the rectangular frame 1 are made of light-guiding material.

[0018] In the actual design, the fan housing is divided into two modules: a rectangular frame 1 and a positioning frame 2. The positioning groove 10 is directly formed in the rectangular frame 1. Therefore, during injection molding, it can be made of two different materials with different colors or light guide properties. When the fan has built-in RGB lights or is installed in the position of RGB lights, the predetermined light illumination effect can be achieved. The combination of the two structures effectively reduces the production cost. At the same time, the positioning groove 10 is set with a large span, which can not only achieve the structural stability of the fan housing, but also improve the light radiation range.

[0019] In a specific embodiment, positioning grooves 10 can be provided on the bottom wall or the top wall of the rectangular frame 1, thus providing a wider coverage of the light source; of course, they can also be provided only on the bottom wall or the top wall.

[0020] Specifically, the rectangular frame 1 includes an outer frame 12 and an inner frame 11, which together form the positioning groove 10. This can be understood as the bottom wall or bottom wall being designed as a hollow structure to serve as the positioning groove 10, thereby facilitating the installation and fixing of the positioning frame 2.

[0021] More specifically, the positioning groove 10 has a closed-loop structure.

[0022] In this embodiment of the utility model, the rectangular frame 1 is provided with at least two corner ends 3, and the corner ends 3 are provided with stepped grooves 31 on the wall surface of the positioning groove 10. The positioning frame 2 is provided with a stepped part 32 extending into the stepped groove 31, thereby realizing the positioning of the rectangular frame 1.

[0023] Specifically, the stepped section and the wall opposite to the rectangular frame 1 are provided with a clearance groove 4. The clearance groove 4 is fitted with a corner cover 5 that matches the shape of the corner end 3, that is, to cover the corner end 3 of the rectangular frame 1, so that the light is directed to a wider area, that is, the corner cover 5 can emit light.

[0024] In this embodiment of the utility model, the corner cover 5 is detachably installed in the clearance groove 4.

[0025] Furthermore, the wall of the clearance groove 4 is provided with a buckle 62, and the inner side wall of the corner cover 5 is provided with a groove 61 that cooperates with the buckle 62, thereby facilitating the fixed installation of the positioning frame 2, that is, limiting the positioning frame 2.

[0026] In this embodiment of the utility model, the positioning frame 2 is provided with a hollow guide post 71, wherein the guide post 71 is a screw hole, and the corresponding rectangular frame 1 and corner cap 5 are also provided with corresponding through holes; the hollow frame is a light guide or a decorative part.

[0027] Specifically, the corner cover 5 also includes a hollow frame 72, which is disposed between the corner cover 5 and the rectangular frame 1. This further improves the light-emitting effect of the fan, namely, three different colors or different light-guiding materials can be used between the corner cover 5, the hollow frame 72 and the rectangular frame 1 to improve the light-guiding effect of the fan.

[0028] In this embodiment of the utility model, the inner frame 11 is provided with a limiting groove 81, and the positioning frame 2 is provided with a limiting part 82 that cooperates with the limiting groove 81, thereby realizing the positioning and fixing of the positioning frame 2.

[0029] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
