Description

Technical Field

[0001] This utility model relates to the field of heat dissipation equipment technology, and in particular to a heat dissipation fan that integrates a multi-digit visual display module. Background Technology

[0002] Cooling fans are common heat dissipation components in electronic devices. Traditional cooling fans have the following defects in terms of visual display, status feedback, installation adaptability and system coordination: (1) The patterns and light decorations set in the center of the fan blades or hub cannot achieve the identification and decoration effect in a static state. The patterns and light decorations will rotate with the fan blades. (2) They cannot intuitively display the operating status of the equipment. Traditional fans can only judge the working status by whether they rotate or not. They lack real-time data feedback (such as speed, temperature, fault warning, etc.), resulting in low operation and maintenance efficiency. (3) They have poor installation and configuration flexibility. Traditional fans rely on screws for fixed assembly, which is inconvenient to assemble and difficult to adapt to different equipment structures, such as compact chassis. (4) They have low system integration. Traditional fans usually operate as independent components and cannot coordinate with other electronic devices or equipment management systems, resulting in low energy efficiency. With the development of intelligent and modular technologies, these defects are becoming increasingly prominent. Therefore, it is urgent to optimize them through technological innovation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cooling fan that integrates multiple visual display modules, ensuring that the patterns and lighting decorations set at the center of the fan blades or hub achieve a static identification and decorative effect, can intuitively display real-time data of equipment operation status, is easy to assemble, and has a high degree of system integration.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A cooling fan integrating a multi-position visual display module includes at least two fan units, each fan unit having a splicing structure. Adjacent fan units are connected via the splicing structure. Each fan unit includes a fan frame, a hollow shaft, a fan blade assembly, a multi-position visual display module, and a magnetic connector. One end of the hollow shaft is rotatably connected to the bottom of the fan frame. The fan blade assembly includes a hub and multiple fan blades disposed within the fan frame. A protruding connecting sleeve is provided at the bottom of the hub, and the connecting sleeve is sleeved on the outside of the hollow shaft. A magnetic top cover is provided on the top of the hub, and a first magnetic component is installed on the magnetic top cover. Multiple fan blades are arranged around the periphery of the hub. The multi-position visual display module includes a front visual display module, a rear visual display module, a first side visual display module, and a second side visual display module. The front visual display module is installed on the top of the magnetic top cover, the rear visual display module is installed on the bottom of the fan frame, and the first and second side visual display modules are respectively installed on two opposite side walls of the fan frame. The display panels of the front visual display module, rear visual display module, first side visual display module, and second side visual display module are LED dot matrix screens, LED digital screens, LCD screens, or OLED displays, etc. The magnetic connector is coaxially inserted into the hollow shaft, and a conductive pin is integrated inside. One end of the magnetic connector is fixed to the rear visual display module and electrically connected through the conductive pin, and the other end is equipped with a second magnetic component that is magnetically attracted to the first magnetic component on the magnetic top cover and electrically connected to the front visual display module through the conductive pin.

[0006] In some embodiments, the splicing structure is a magnetic connector. The splicing structure includes a male splice and a female splice respectively installed on two opposite sidewalls of the fan frame. The male splice includes a first magnet block and a plurality of first spring pins spaced apart on the first magnet block. The first spring pins protrude from the sidewall of the fan frame. The female splice includes a second magnet block and a plurality of first fixed contacts spaced apart on the second magnet block. The second magnet block and the first magnet block have opposite poles facing each other. The first fixed contacts are adapted to the first spring pins.

[0007] In some embodiments, the magnetic top cover has a central hole in the middle, a mounting groove is coaxially provided at the top of the central hole, and a snap-fit ​​groove is coaxially provided at the bottom of the central hole; the first magnetic element is a ring magnet, which is fixed in the mounting groove.

[0008] In at least one embodiment, the magnetic connector includes a central shaft and a fixed disk. The central shaft is coaxially inserted into the hollow shaft, and there is a gap between the central shaft and the inner wall of the hollow shaft. The bottom end of the central shaft is fixedly connected to the rear visual display module, and the top end of the central shaft is inserted into the central hole. The fixed disk is coaxially fixed to the top of the central shaft, and the fixed disk is adapted to the snap-fit ​​groove. The second magnetic connector is a ring magnet, which is fixed inside the fixed disk.

[0009] Compared with the prior art, this utility model achieves at least the following beneficial effects:

[0010] This invention uses a magnetic connector to attach a magnetic top cover with a front visual display module to the top of the hub. When the hub rotates around its hollow shaft, the magnetic connector remains fixed, preventing the front visual display module from rotating with the hub and fan blades. This allows the front visual display module on top of the fan blade assembly to achieve a static visual effect. The rear visual display module is installed at the bottom of the fan frame, and the first and second side visual display modules are respectively installed on the side walls of the fan frame, also achieving a static visual effect. By using multiple visual display modules, the hardware status can be visualized through multi-character and multi-parameter displays. The system displays information such as cooling fan speed, equipment temperature, equipment status, runtime, and fault warnings. The display panels of the front vision display module, rear vision display module, first-side vision display module, and second-side vision display module can be LED dot matrix screens, LED digital screens, LCD screens, or OLED displays. In addition, multiple vision display modules can be linked with related electronic devices to further expand personalized monitoring functions such as environmental monitoring and dust monitoring. The system has a high degree of integration. Multiple fan units can be spliced ​​together into one unit without the need for screw fixing, making assembly convenient and adaptable to compact chassis.

[0018] like Figures 1-3As shown in the embodiment of this application, a cooling fan integrating a multi-digit visual display module includes at least two fan units 1. Each fan unit 1 is provided with a splicing structure 2. Two adjacent fan units 1 are connected by the splicing structure 2. Multiple fan units 1 can be spliced ​​together into one unit and installed on a computer to meet the computer's heat dissipation requirements. Each fan unit 1 includes a fan frame 3, a hollow shaft 4, a fan blade assembly 5, a multi-position visual display module 6, and a magnetic connector 7. One end of the hollow shaft 4 is rotatably connected to the bottom of the fan frame 3. The fan blade assembly 5 includes a hub 51 and multiple fan blades 52 disposed within the fan frame 3. A protruding connecting sleeve 511 is provided at the bottom of the hub 51, which is sleeved on the outside of the hollow shaft 4. A magnetic top cover 8 is provided on the top of the hub 51, and a first magnetic connector 9 is installed on the magnetic top cover 8. Multiple fan blades 52 are arranged around the periphery of the hub 51, and the fan blades 52 are integrally formed with the hub 51. The hub 51 can rotate around the axis of the hollow shaft 4 within the fan frame 3. Block 6 visualizes hardware status through multi-character, multi-parameter display, showing information such as cooling fan speed, device temperature, device status, runtime, and fault warnings. Furthermore, the multi-view display module 6 can be linked with related electronic devices to expand personalized functions such as environmental monitoring and dust detection. The multi-view display module 6 includes a front view display module 61, a rear view display module 62, a first-side view display module 63, and a second-side view display module 64. Each of these modules includes a display unit and a control unit. The system includes a control and drive unit, a data interaction unit, and a power supply unit. The display unit includes a display panel, which can be an LED dot matrix screen, LED digital screen, LCD screen, OLED display, etc., and can be selected according to display requirements. The control and drive unit is responsible for receiving hardware data, processing display logic, and driving the display panel. The data interaction unit is responsible for acquiring external hardware status data such as temperature and speed. The power supply unit provides a stable power supply. A front visual display module 61 is mounted on the top of the magnetic top cover 8, and a rear visual display module 62 is mounted on the bottom of the fan frame 3. A first-side visual display module 63 and a second-side visual display module 64 are also included. 4 are respectively installed on two opposite side walls of the fan frame 3. The multi-position visual display module 6 can be a single-direction display module or a combination of multi-position display modules, that is, a display module is installed in only one position or multiple positions at the same time. The magnetic connector 7 is coaxially inserted into the hollow shaft. The conductive pin 20 is integrated inside. One end of the magnetic connector 7 is fixed and electrically connected to the rear visual display module 62 through the conductive pin 20. The other end is equipped with a second magnetic connector 10 that is attracted by the first magnetic connector 9 on the magnetic top cover 8 through magnetic force, and is electrically connected to the front visual display module 61 through the conductive pin 20.

[0019] This invention uses a magnetic connector 7 to attach a magnetic top cover 8, on which a front visual display module 61 is mounted, to the top of the hub 51. Assembly is simple and convenient. When the hub 51 rotates around the hollow shaft 4, the magnetic connector 7 remains fixed, preventing the front visual display module 61 from rotating with the hub 51 and the fan blades 52. This allows the front visual display module 61 on the top of the fan blade assembly 5 to achieve a static visual effect. The rear visual display module 62 is mounted at the bottom of the fan frame 3, and the first side visual display module 63 and the second side visual display module 64 are mounted on the side walls of the fan frame 3. The rear visual display module 62, the first side visual display module 63, and the second side visual display module 64 can also achieve a static visual effect. Multiple fan units 1 can be spliced ​​together into one unit through the splicing structure 2 without the need for screws. Assembly is convenient and it can be adapted to compact chassis.

[0020] refer to Figure 1 Optionally, the splicing structure 2 is a magnetic connector structure. The splicing structure 2 includes a male splicing component 21 and a female splicing component 22 respectively installed on the opposite side walls of the other two sides of the fan frame 3. The male splicing component 21 includes a first magnet block 211 and a plurality of first spring pins 212 spaced apart on the first magnet block 211. The first spring pins 212 protrude from the side wall of the fan frame 3. The female splicing component 22 includes a second magnet block 221 and a plurality of first fixed contacts 222 spaced apart on the second magnet block 221. The second magnet block 221 and the first magnet block 211 are opposite poles facing each other. When they are close together, they will generate an attraction. The first fixed contacts 222 are adapted to the first spring pins 212. It should be noted that when the two fan units 1 are spliced ​​together, they can be quickly connected by adsorption through the first magnet and the second magnet. When the first magnet and the second magnet are connected by adsorption, the first spring pin 212 contacts the first fixed contact 222 and the first spring pin 212 retracts, thereby achieving a tight contact between the first spring pin 212 and the first fixed contact 222, and realizing the electrical connection between the two fan units 1. The composition of the first spring pin 212 is existing technology, so it will not be described in detail.

[0021] This utility model replaces the traditional cable connection with a splicing structure 2. The splicing structure 2 is a magnetic connector structure that integrates high-density electrical connection, high-speed data communication and intelligent management protocol, eliminating the drawbacks of the relatively cumbersome traditional cable connection and realizing quick connection and disassembly.

[0022] refer to Figures 3-4Optionally, the magnetic top cover 8 has a central hole 81 in the middle, a mounting groove 82 coaxially provided at the top of the central hole 81, and a snap-fit ​​groove 83 coaxially provided at the bottom of the central hole 81; the first magnetic component 9 is a ring magnet, which is fixed in the mounting groove 82. The magnetic connector 7 includes a central shaft 71 and a fixing plate 72. The central shaft 71 is coaxially inserted into the hollow shaft 4, and there is a gap between the central shaft 71 and the inner wall of the hollow shaft 4. The bottom end of the central shaft 71 is fixedly connected to the rear visual display module 62, and the top end of the central shaft 71 is inserted into the central hole 81. The fixing plate 72 is coaxially fixed to the top of the central shaft 71, and the fixing plate 72 is adapted to the snap-fit ​​groove 83; the second magnetic component 10 is a ring magnet, which is fixed in the fixing plate 72. It should be noted that when assembling the magnetic top cover 8 with the front visual display module 61 and the magnetic connector 7, the top of the central shaft 71 of the magnetic connector 7 is inserted into the central hole 81, the fixing plate 72 is engaged in the snap-fit ​​groove 83, and the second magnetic component 10 attracts the first magnetic component 9, thereby making the magnetic top cover 8 and the magnetic connector 7 stably connected together. In addition, a tapered guide hole is provided at the top of the connecting sleeve 511 of the hub 51, and a tapered protrusion adapted to the tapered guide hole is provided at the bottom of the magnetic top cover 8. The aforementioned snap-fit ​​groove 83 is recessed at the bottom of the tapered protrusion.

[0023] The front vision display module 61 is provided with multiple second fixed contacts (not shown in the figure) above the central hole 81; multiple stepped through holes 711 are opened along the length direction on the central shaft 71, and conductive pins 20 are inserted and fixed in the stepped through holes 711. The bottom end of the conductive pin 20 is welded and fixed to the rear vision display module 62 and electrically connected. The top end of the conductive pin 20 is provided with a second spring pin 201 that is adapted to the second fixed contacts. The second spring pin 201 is used to contact and electrically connect with the second fixed contacts. The second spring pin 201 is provided with a shoulder that is adapted to the stepped through hole 711, and the shoulder abuts against the stepped surface of the stepped through hole 711. The composition of the second spring pin 201 is prior art, so it will not be described in detail.

[0024] The fan frame 3 includes a fan frame 31 and a top cover 32 detachably connected to the top of the fan frame 31. A mounting plate 311 is provided in the middle of the bottom surface of the fan frame 31. Several connecting ribs 312 are fixedly connected between the mounting plate 311 and the fan frame 31. A protruding mounting sleeve 3111 is provided on the top of the mounting plate 311. The fan frame 3 also includes a drive assembly 30, which includes a coil bracket 301 and a drive circuit board 302. The coil bracket 301 is sleeved on the outside of the mounting sleeve 3111. A coil (not shown in the figure) is wound on the coil bracket 301. The coil is electrically connected to the drive circuit board 302. The drive circuit board 302 is mounted on the mounting plate 311. The inner sidewall of the hub 51 is provided with an annular magnetic strip 512 adapted to the coil along the circumferential direction. The annular magnetic strip 512 has alternating magnetic poles and interacts with the coil on the coil bracket 301 to generate a magnetic field. It should be noted that when the cooling fan is powered on, the coil generates an induced magnetic field and interacts with the annular magnetic strip 512 on the hub 51 to generate a force, thereby driving the hub 51 to rotate around the axis of the hollow shaft 4, which in turn drives the fan blades 52 to rotate and generate airflow. The composition of the drive assembly 30 is existing technology, so it will not be described in detail.

[0025] The bottom of the mounting sleeve 3111 is coaxially provided with a bearing 40, the outer ring of which is fixedly connected to the mounting sleeve; one end of the hollow shaft 4 is fixedly connected to the inner ring of the bearing 40, so that the hollow shaft 4 can rotate within the fan frame 3.

[0026] The connecting sleeve 511 of the hub 51 is suspended inside the mounting sleeve 3111, and a bushing 50 is provided between the connecting sleeve 511 and the hollow shaft 4. The bushing 50 is sleeved on the outside of the hollow shaft 4, and the connecting sleeve 511 is sleeved on the outside of the bushing 50. The bushing 50 can prevent the connecting sleeve 511 from directly rubbing against the hollow shaft 4.

[0027] refer to Figures 2-3 Optionally, the front visual display module 61, the rear visual display module 62, the first side visual display module 63, and the second side visual display module 64 are all covered with a transparent protective cover 60. The transparent protective cover 60 can be fixedly connected to the exterior of the front visual display module 61 and the rear visual display module 62 by means such as adhesive bonding, or it can be connected to the fan frame 3 outside the first side visual display module 63 and the second side visual display module 64 by means such as plug-in connection. A flexible circuit board 70 connects the first side visual display module 63 and the second side visual display module 64.

[0028] It should be understood that all the above embodiments are exemplary and not restrictive. Any modifications, equivalent changes and alterations made by those skilled in the art to the specific embodiments described above under the concept of this utility model shall still fall within the scope of the technical solution of this utility model.
