Description

Technical Field

[0001] This utility model relates to the field of graphics card fan technology, specifically a graphics card cooling fan structure with projection effect. Background Technology

[0002] A graphics card is a fundamental component of a personal computer. It converts the display information required by the computer system to drive the monitor and provides progressive or interlaced scanning signals to control the correct display. It is an important component connecting the monitor and the motherboard of the personal computer. Graphics cards are usually installed inside the computer case. Because they generate a lot of heat during use, they need to be equipped with cooling fans to dissipate heat.

[0003] Currently, some computer cases add LED light strips next to the graphics card cooling fan. This allows for a 3D naked-eye visual effect through the high-speed rotating fan blades and the brightness and color of the LED lights, i.e., fan projection, which increases the fun of using the case and gives it a decorative function. However, in the current technology, both the graphics card cooling fan and the LED light holder are installed inside the case with multiple bolts, which makes the disassembly and assembly process cumbersome and inconvenient for maintenance. Furthermore, the fixed spacing between the graphics card cooling fan and the LED light holder results in a monotonous projection effect and a mediocre decorative effect.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing equipment. Therefore, we have proposed a graphics card cooling fan structure with projection effects that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a graphics card cooling fan structure with projection effect, so as to solve the problem mentioned in the background art that in the prior art, the graphics card cooling fan and LED light holder are installed inside the chassis by multiple bolt fasteners, which makes the disassembly and assembly steps more cumbersome and inconvenient for inspection and maintenance. In addition, the fixed spacing between the graphics card cooling fan and the LED light holder results in a monotonous projection effect and a mediocre decorative and viewing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a graphics card cooling fan structure with projection effect, including a mounting bracket mounted on a chassis, with a fan body mounted on the bottom of the mounting bracket via a fan housing; a mounting base mounted on top of the fan housing, with an LED light strip fixedly mounted inside the mounting base, and a transparent protective frame covering the top of the LED light strip; the mounting base is mounted on the mounting bracket via a convenient installation component, the convenient installation component including two movable clamping plates slidably connected to the bottom of the mounting bracket, a clamping groove formed on the inner top of the movable clamping plate, and the two sides of the mounting base engaging with the inner side of the clamping groove; protruding plates formed at both ends of the movable clamping plates, and the two ends of the mounting base engaging between the protruding plates; a fixing plate fixedly connected to the bottom end of the mounting bracket outside the movable clamping plates, and multiple evenly distributed springs fixedly connected between the fixing plate and the movable clamping plates; the fan housing and the mounting base are movably connected via a height adjustment component to adjust the distance between the fan body and the LED light strip to enrich the projection effect.

[0007] Preferably, the bottom of the two movable clamps on the side that is close to each other is formed as an inclined surface, and the two inclined surfaces are in the shape of an "eight".

[0008] Preferably, the top of the movable clamp is fixedly connected to a connecting plate via connecting posts at both ends, and the connecting posts slide through the mounting frame.

[0009] Preferably, the height adjustment assembly includes two sets of lifting rods rotatably connected to both sides of the fan housing and the mounting base. The bottom end of the lifting rod is rotatably connected to both ends of the side wall of the fan housing via a fixed shaft. The top end of the lifting rod is rotatably connected to a movable seat via a fixed shaft. A double-acting screw is threaded between two movable seats located on the same side. A motor is fixedly installed at the bottom end of the mounting base, and one end of the motor's output shaft is connected to the double-acting screw.

[0010] Preferably, a stable central shaft is rotatably connected between the intersection points of the two sets of lifting rods, and the stable central shaft is transparent and runs horizontally between the fan housing and the mounting base.

[0011] Preferably, the top of the movable seat is formed with a protrusion, and the bottom of the mounting seat is provided with a groove that matches the size of the protrusion, and the protrusion slides on the inner side of the groove.

[0012] Preferably, a transmission assembly is provided between the two bidirectional lead screws, the transmission assembly consisting of a transmission wheel fixedly connected to the outer wall of the bidirectional lead screw and a transmission belt on the outer side of the two transmission wheels.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This graphics card cooling fan structure with projection effect, by setting a convenient installation component, only needs to push the movable clamps on both sides outward to disengage from the mounting base, and the spring is compressed, so that the mounting base can be removed from the mounting frame as a whole, thereby simplifying the disassembly and assembly steps, so as to facilitate inspection and maintenance. At the same time, by using the height adjustment component to connect the fan shell and the mounting base, the distance between the two can be adjusted to enrich the projection effect. The specific contents are as follows: (1) By setting a convenient installation component, multiple springs push the two movable clamps close together, so that the mounting base can be firmly locked between the clamping grooves, and the protruding plates at both ends of the movable clamps can further limit the mounting base, thereby realizing the stable installation of the LED light strip and the fan body. When disassembling, only need to push the movable clamps on both sides outward to disengage from the mounting base, so that the mounting base can be removed from the mounting frame as a whole, thereby simplifying the disassembly and assembly steps, so as to facilitate inspection and maintenance.

[0014] (2) By using the “eight” shaped inclined structure of the movable clamping plate, when installing the mounting base, the two sides of the plate can be pushed upward against the two inclined surfaces, which will push the two movable clamping plates apart to the sides and compress the spring. In this way, the mounting base can smoothly enter the clamping groove. At this time, the spring rebounds and the two sides of the mounting base are stably clamped in the clamping groove, thus realizing the convenient installation of the mounting base.

[0015] (3) By setting the height adjustment component, the motor drives the bidirectional lead screw to rotate, and the moving seat will slide symmetrically along the outside of the bidirectional lead screw. The cross angle of the two lifting rods changes, that is, the distance between the mounting base and the fan housing is adjusted, and the projected image will become larger or smaller accordingly, thereby diversifying the projection effect and improving the decorative and viewing effect of this fan projection device.

[0016] (4) By setting a stable central axis between the intersection of the two sets of lifting rods, the synchronous change of the intersection angle of the two lifting rods can be ensured without affecting the projection effect, so that the fan housing can be raised and lowered smoothly, thus ensuring the stable scaling of the projected image.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a graphics card cooling fan structure with projection effect, including a mounting bracket 1 installed on a chassis, a fan body 3 installed at the bottom of the mounting bracket 1 via a fan housing 2; a mounting base 4 installed on top of the fan housing 2, an LED light strip 5 fixedly installed inside the mounting base 4, and a transparent protective frame 6 covering the top of the LED light strip 5; the mounting base 4 is installed on the mounting bracket 1 via a convenient installation component, the convenient installation component including two movable clamps 7 slidably connected to the bottom of the mounting bracket 1, the movable clamps 7... The top inner side is formed with a clamping groove 8, and the two sides of the mounting base 4 are engaged with the inner side of the clamping groove 8. The two ends of the movable clamping plate 7 are formed with protrusions, and the two ends of the mounting base 4 are engaged between the protrusions. The bottom end of the mounting frame 1 is located outside the movable clamping plate 7 and is fixedly connected with a fixing plate 9. A plurality of evenly distributed springs 10 are fixedly connected between the fixing plate 9 and the movable clamping plate 7. The top end of the movable clamping plate 7 is fixedly connected with a connecting plate 11 through the connecting columns at both ends. The connecting columns slide through the mounting frame 1, so that the movable clamping plate 7 can slide stably at the bottom of the mounting frame 1.

[0026] By pushing the two movable clamping plates 7 together with multiple springs 10, the mounting base 4 can be securely engaged between the two clamping slots 8. The protruding plates at both ends of the movable clamping plates 7 can limit the mounting base 4 in the vertical direction, thereby achieving a secure installation of the LED light strip 5 and the fan body 3. When disassembly is required, simply push the movable clamping plates 7 on both sides outward until they are no longer in contact with the mounting base 4. The springs 10 will be compressed, and the mounting base 4, LED light strip 5, fan housing 2, and fan body 3 can be removed from the mounting bracket 1 as a whole, thus simplifying the disassembly and assembly steps and facilitating inspection and maintenance.

[0027] The bottom of the two movable clamping plates 7 that are close to each other is formed into an inclined surface, and the two inclined surfaces are in the shape of an "eight". When installing the mounting base 4, it can be pushed upward against the two inclined surfaces on both sides, which will push the two movable clamping plates 7 to both sides, so that the spring 10 is compressed. In this way, the mounting base 4 can smoothly enter between the two clamping grooves 8. At this time, the spring 10 rebounds, so that the two sides of the mounting base 4 are stably clamped inside the clamping grooves 8, thereby realizing the convenient installation of the mounting base 4.

[0028] Example 2: Based on Example 1, the fan housing 2 and the mounting base 4 are movably connected via a height adjustment assembly to adjust the distance between the fan body 3 and the LED light strip 5 to enrich the projection effect. The height adjustment assembly includes two sets of lifting rods 12 rotatably connected to both sides of the fan housing 2 and the mounting base 4. The bottom end of the lifting rod 12 is rotatably connected to both ends of the side wall of the fan housing 2 via a fixed shaft 14. The top end of the lifting rod 12 is rotatably connected to a movable seat 15 via the fixed shaft 14. The top end of the movable seat 15 is formed with a protrusion, and the bottom end of the mounting base 4 is provided with a groove matching the size of the protrusion. The protrusion slides inside the groove to ensure the stability of the movable seat 15 sliding linearly along the surface of the mounting base 4. A bidirectional lead screw is threaded between the two movable seats 15 on the same side. 16. A motor 17 is fixedly installed at the bottom of the mounting base 4, and one end of the output shaft of the motor 17 is connected to the bidirectional lead screw 16. A transmission group 18 is provided between the two bidirectional lead screws 16. The transmission group 18 consists of a transmission wheel fixedly connected to the outer wall of the bidirectional lead screw 16 and a transmission belt on the outside of the two transmission wheels. Through the transmission group 18, the motor 17 can drive the two bidirectional lead screws 16 to rotate synchronously, thereby saving power resources. When the motor 17 drives the two bidirectional lead screws 16 to rotate, the moving base 15 will slide symmetrically along the outside of the bidirectional lead screw 16. The cross angle of the two lifting rods 12 changes, that is, the distance between the mounting base 4 and the fan housing 2 is adjusted. The projected image will become larger or smaller accordingly, thereby diversifying the projection effect and improving the decorative and viewing effect of this fan projection device.

[0029] In addition, a stabilizing central axis 13 is rotatably connected between the intersection points of the two sets of lifting rods 12. The stabilizing central axis 13 is transparent and runs horizontally between the fan housing 2 and the mounting base 4. By setting the stabilizing central axis 13, the synchronous change of the intersection angle of the two lifting rods 12 can be ensured without affecting the projection effect, so that the fan housing 2 can be raised and lowered smoothly, thus ensuring the stable scaling of the projected image.
