DETAILED DESCRIPTION

[0019] The exemplary embodiments of the present application will be described herein below with reference to the accompanying drawings. While the exemplary embodiments of the present application are shown in the drawings, it is to be understood that the present application can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0020] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present application should be understood as their common meanings to those skilled in the art to which the present application pertains.

[0021] In the existing light effect fan scheme, there is a contradiction between realizing dynamic light effect in the frame and ensuring the diameter of the fan blade to maintain the heat dissipation performance. If dynamic light effect is to be realized in the frame, the thickness of the frame needs to be increased, thereby reducing the diameter of the fan blade and reducing the heat dissipation performance; if the diameter of the fan blade is maximized to maintain the heat dissipation performance, the dynamic light effect of the side of the frame is sacrificed, affecting the user experience.

[0022] The fan provided by the embodiments of the present application effectively solves the above technical problems by dividing the accommodation space into a first area (for setting the rotating body to ensure its maximum diameter) and a second area (for setting the first light emitting member to realize dynamic light effect), and realizes dynamic light effect experience for users without reducing the heat dissipation performance.

[0023] Embodiment 1

[0024] The embodiment of the present application provides a fan, which comprises a housing 1, a rotating body 2 and a first light-emitting element 3. Figure 1 As shown in the figure, the fan comprises a housing 1, a rotating body 2 and a first light-emitting element 3. The housing 1 has an accommodation space inside, and the accommodation space comprises a first region 103 and a second region 104. The first region 103 is a maximum circular region in the projected area of the accommodation space in the direction perpendicular to the rotating axis of the rotating body 2. The rotating body 2 is arranged in the first region 103, and the diameter size of the rotating body 2 is adapted to the diameter size of the maximum circular region. The second region 104 is a peripheral region of the first region 103, and the first light-emitting element 3 is arranged in the second region 104. The light of the first light-emitting element 3 can pass through the housing 1 and be transmitted to the outside.

[0025] The fan is composed of the housing 1, the rotating body 2 and the first light-emitting element 3. The housing 1 is a protection structure of the fan, and has an accommodation space inside. The accommodation space is divided into the first region 103 and the second region 104.

[0026] The first region 103 is a maximum circular region in the projected area of the accommodation space in the direction perpendicular to the rotating axis of the rotating body 2. The rotating body 2, for example, the fan blade and the rotating component connected thereto, is arranged in the first region 103. The rotating body 2 can generate airflow by rotating. The diameter size of the rotating body 2 is adapted to the diameter size of the maximum circular region, which means that the rotating body 2 can be fully unfolded in the first region 103 to realize the maximum diameter in the accommodation space. By making the rotating body 2 obtain a larger diameter size, the effective heat dissipation area of the fan can be ensured, thereby improving the heat dissipation performance.

[0027] The second region 104 is a peripheral region of the first region 103, and the first light-emitting element 3 is arranged in the second region 104. Since the first light-emitting element 3 is arranged in the peripheral region of the first region 103, that is, the region around the rotating body 2, and the light of the first light-emitting element 3 can pass through the housing 1 and be transmitted to the outside, the dynamic light effect display of the fan can be realized without affecting the diameter of the rotating body 2, that is, without reducing the diameter of the fan blade.

[0028] The fan provided by the embodiment of the present application can realize the dynamic light effect without sacrificing the diameter of the fan blade by arranging the first light-emitting element 3 in the second region 104 on the peripheral side of the first region 103. Compared with the case that the diameter of the fan blade is reduced in the traditional scheme for realizing the light effect in the frame, the fan provided by the embodiment of the present application not only improves the heat dissipation performance, but also better meets the heat dissipation demand of the electronic equipment. Moreover, the light emitted by the first light-emitting element 3 is transmitted to the user through the housing 1, which brings the user a visual experience and meets the demand of the user for the light effect display of the electronic equipment.

[0029] In some embodiments, asFigure 1 As shown, the shell 1 comprises a first frame 101 and a second frame 102, the second frame 102 is connected with the first frame 101 to form a containing space; the first frame 101 comprises a bottom plate 105 and an annular mounting plate 106, the annular mounting plate 106 is vertically arranged on the bottom plate 105; the bottom plate 105 is square, the outer surface of the annular mounting plate 106 is tangent to the side of the bottom plate 105, the area enclosed by the annular mounting plate 106 is the first area 103, the diameter size of the rotating body 2 is adapted to the inner diameter size of the annular mounting plate 106.

[0030] The shell 1 of the fan adopts a split design, which is composed of the first frame 101 and the second frame 102. The first frame 101 serves as the basic framework, and the bottom plate 105 thereof is made of square plate material to provide stable bottom support for the fan. The second frame 102 can be a square frame structure adapted to the bottom plate 105. The first frame 101 and the second frame 102 can be cooperatively connected by bolts, clamping, etc. to form the shell 1 of the fan. The annular mounting plate 106 can be vertically arranged on the bottom plate 105 by welding, plugging, bolt connection, etc., similar to a standing ring. The outer surface of the annular mounting plate 106 is tangent to the side of the bottom plate 105, and the range enclosed thereby is the largest circular area (the first area 103) in the shell 1, which is used for disposing the rotating body 2.

[0031] The wall thickness of the annular mounting plate 106 can be set according to actual conditions, and the minimum wall thickness that can meet the strength can be selected. In this way, by adapting the diameter size of the rotating body 2 to the inner diameter size of the annular mounting plate 106, the maximum size of the rotating body 2 can be realized.

[0032] During installation, the fan blades and other rotating components can be placed in the first area 103 enclosed by the annular mounting plate 106, so that the diameter size of the rotating body 2 is adapted to the inner diameter size of the annular mounting plate 106, that is, the diameter size of the rotating body 2 can meet the setting in the first area 103 and the annular mounting plate 106 will not interfere with the rotation of the rotating body 2. Then the second frame 102 is connected with the first frame 101 to form a closed containing space, which protects the internal rotating body 2 and the first light emitting element 3. The first light emitting element 3 is arranged on the side of the annular mounting plate 106, that is, in the space outside the first area 103, and the light emitted by the first light emitting element 3 can be transmitted to the outside through the material of the shell 1 to realize dynamic light effect display.

[0033] The shell 1 is connected by buckling the first frame 101 and the second frame 102, which simplifies the assembly process of the fan. The annular mounting plate 106 is precisely adapted to the diameter of the rotating body 2, which ensures that the fan blades can operate at the maximum size and fully exert their heat dissipation capacity. Arranging the first light-emitting piece 3 in the second area 104 on the side of the first area 103 can ensure the heat dissipation performance of the fan and realize dynamic light effect display without changing the size of the rotating body 2.

[0034] In some embodiments, as shown in Figure 1 The fan further comprises a lamp strip 4, which is annularly arranged on the surface of the annular mounting plate 106 away from the first area 103, and the lamp strip 4 is connected with a first connector 401 for connecting with a power supply; and the first light-emitting piece 3 is electrically connected with the lamp strip 4.

[0035] The lamp strip 4 can be a flexible circuit board in a strip shape, which is tightly annularly arranged on the surface of the annular mounting plate 106 away from the first area 103. The annular mounting plate 106 provides a stable mounting position for the lamp strip 4, which ensures that the lamp strip 4 can be arranged along the contour of the annular mounting plate 106. The lamp strip 4 is connected with the first connector 401, which can be a pin or a board, facilitating the connection with an external power supply interface to supply power to the lamp strip 4 and the first light-emitting piece 3.

[0036] The first light-emitting piece 3 can be an LED lamp bead or a lamp sheet arranged on the lamp strip 4, and the first light-emitting piece 3 is electrically connected with the lamp strip 4. When the power is turned on, the current is transmitted to the lamp strip 4 through the first connector 401, and then transmitted to each first light-emitting piece 3 through the lamp strip 4, so that the first light-emitting piece 3 is lit.

[0037] By annularly arranging the lamp strip 4 on the surface of the annular mounting plate 106 away from the first area 103, the space of the rotating body 2 is avoided to be occupied, so as to ensure the maximization of the diameter of the rotating body 2. By arranging a plurality of first light-emitting pieces 3 on the lamp strip 4, and connecting the lamp strip 4 with the first connector 401, it is ensured that the light brightness, color and flicker frequency of all the first light-emitting pieces 3 are consistent, so that the fan presents a more harmonious and beautiful dynamic light effect.

[0038] In some embodiments, the first light-emitting piece 3 comprises a plurality of light control modules for controlling the color and / or brightness of the lamp strip 4; and the second area 104 is divided into a plurality of parts by the annular mounting plate 106, and the plurality of light control modules are evenly arranged in each second area 104.

[0039] The annular mounting plate 106 divides the second area 104 into several independent parts, for example, it can be divided into 4 or 6 sectors. In the embodiment of the application, the fan is a cuboid structure, the bottom plate 105 is a square, the annular mounting plate 106 is vertically arranged on the bottom plate 105, and the outer surface of the annular mounting plate 106 is tangent to the four sides of the bottom plate 105, so that the second area 104 is divided into 4, and the four sub-areas are the four corners of the housing 1. The light control module is uniformly arranged in each second area 104, and the module can be a small integrated circuit board which integrates microcontrollers, drive chips and other elements. The light control module adjusts the color and brightness of the lamp strip 4 by receiving external control signals such as instructions from the fan control circuit or connected devices.

[0040] The first light-emitting part 3 in the fan of the embodiment of the application can be an ARGB light source, and the light control module is an ARGB mode in the first light-emitting part 3. The ARGB mode is a color mode for representing color information containing transparency and three basic colors (red, green, and blue). By controlling the color and brightness of different parts of the first light-emitting part 3, the light effect display form of the fan is greatly enriched. Complex and gorgeous dynamic light effects such as flowing water lamp, color gradient, and regional flashing can be achieved to meet the diverse needs of users for personalized light effects.

[0041] The plurality of light control modules are distributed in each second area 104, that is, the plurality of first light-emitting parts 3 are uniformly arranged in each second area 104. Since the first light-emitting part 3 has a certain thickness, by uniformly arranging the plurality of first light-emitting parts 3 in each second area 104, only the ultra-thin lamp strip 4 is present at the position where the annular mounting plate 106 is tangent to the bottom plate 105, and no light source is designed. In this way, when the first frame body 101 and the second frame body 102 are buckled, the diameter of the fan blade can be maximized and the frame can be thinnest.

[0042] In some embodiments, as shown in Figure 1 The second frame body 102 includes a top plate 107 and a side frame 108, and in the state that the second frame body 102 is buckled with the first frame body 101, the side frame 108 is located at the outer circumferential side of the annular mounting plate 106; the first light outlet 109 is arranged on the top plate 107 at the position of the second area 104, and the second light outlet 110 is arranged on the side frame 108 at the position of the second area 104.

[0043] The second frame body 102 is composed of a top plate 107 and a side frame 108. The top plate 107 can be a square plate structure, and the side frame 108 is a plate structure vertically arranged around the edge of the top plate 107. The two are fixed together by welding, buckle connection or one-piece forming, etc. to fit the second frame body 102. The bottom plate 105 of the second frame body 102 can be provided with a plurality of limiting columns, and the top plate 107 is provided with a plurality of limiting holes. When the second frame body 102 is buckled with the first frame body 101, the connecting members such as bolts can be bolted through the limiting holes and the limiting columns, so that the side frame 108 is sleeved on the outer circumferential side of the annular mounting plate 106, forming a close fit to ensure the stability of the overall structure of the fan.

[0044] A plurality of first light outlets 109 are processed on the top plate 107 corresponding to the position of the second area 104 by processes such as die stamping and laser cutting. These first light outlets 109 can be circular, square, strip-shaped or other shaped holes, and their size and number are designed according to actual light effect requirements. Similarly, the second light outlets 110 are also processed on the side frame 108 corresponding to the position of the second area 104. The second light outlets 110 can be square holes, strip-shaped holes, grid-shaped holes, etc. The light emitted by the first light emitting member 3, part of which is transmitted upward through the first light outlets 109 on the top plate 107, and the other part is dispersed to the side through the second light outlets 110 of the side frame 108, thereby realizing multi-angle light effect display.

[0045] The arrangement of the first light outlets 109 and the second light outlets 110 enables the light emitted by the first light emitting member 3 to be emitted from the top plate 107 and the side frame 108 in two directions, realizing multi-angle light effect display. Whether the user looks down from above the fan or from the side, he can enjoy the magnificent dynamic light effect, greatly improving the visual range and visual impact of the light effect and enhancing the user's viewing experience.

[0046] In some embodiments, as shown in Figure 1 The fan further comprises a light uniformizing member 5 arranged in the second area 104 and located between the side frame 108 and the annular mounting plate 106, for light uniformizing of the plurality of light control modules.

[0047] The light uniformizing member 5 can be made of a material with good light transmission and diffuse reflection characteristics, such as milky white acrylic, PC diffusion plate, etc. One light uniformizing member 5 is arranged in each second area 104. The light uniformizing member 5 can be a frame structure, and its outer surface size is adapted to the inner surface size of the side frame 108. The light uniformizing member 5 can be provided with an avoidance area for avoiding the connection position of the first frame body 101 and the second frame body 102. For example, the surface of the light uniformizing member 5 can be provided with a through hole, and the light uniformizing member 5 can be connected with the limiting column of the bottom plate 105 through the through hole, thereby realizing the fixation of the light uniformizing member 5.

[0048] The light control module controls the light emitted by the first light emitting member 3 to first irradiate the light uniformizing member 5, and the light uniformizing member 5 scatters and refracts the light to redistribute the light that may have uneven brightness and color difference, so that the light transmitted from the first light outlet 109 and the second light outlet 110 is more uniform and soft.

[0049] In some embodiments, one side of the light uniformizing member 5 facing the side frame 108 is provided with a groove, and the groove is arranged opposite to the second light outlet 110 on the side frame 108; further comprising: a multi-layer mirror module 6 and an outer mirror 7, the multi-layer mirror module 6 is embedded in the groove, and the outer mirror 7 is installed in the second light outlet 110.

[0050] The light uniformizing member 5 can be processed by injection molding or cutting process to form grooves on the side facing the side frame 108, and the shape and size of the grooves correspond to the second light outlet 110 on the side frame 108. The multi-layer mirror module 6 can be composed of multiple layers of reflective lenses and spacing layers, and has a unique optical reflection effect, which is embedded in the groove of the light uniformizing member 5 to ensure stable installation.

[0051] The outer mirror 7 can be made of transparent or optically active materials such as acrylic plates, glass, etc. It is installed in the second light outlet 110 of the side frame 108 by buckling, glueing or screwing, etc. The outer mirror 7 covers the multi-layer mirror module 6 to form a complete light outlet structure. When the light control module controls the first light emitting member 3 to emit light, the light first passes through the light uniformizing member 5 for preliminary uniformization, then enters the multi-layer mirror module 6, and is reflected between multiple layers of reflective lenses to produce a light and shadow effect with depth and level, and finally transmits to the outside through the outer mirror 7.

[0052] Through multiple reflections of light in the multi-layer mirror, a light and shadow tunnel similar to an infinite extension is formed, which greatly enriches the visual level compared to ordinary light effects, and brings users a novel and shocking visual experience, and improves the uniqueness and attractiveness of the product in appearance display.

[0053] In some embodiments, as shown in Figure 1 and Figure 2 The fan further comprises: a circuit board 8, which is laid on the first frame 101, and the first interface 801 and the second interface 802 are connected on the circuit board 8, the first interface 801 is plugged with the first connector 401, and the second interface 802 is used to connect with the power supply; and a second light emitting member 9, which is arranged on the first frame 101 and corresponds to the center position of the rotating body 2, and the second light emitting member 9 is electrically connected with the circuit board 8 to provide light source for the rotating body 2.

[0054] The circuit board 8 can be a printed circuit board (PCB) customized according to the shape and size of the first frame 101, laid flat on the bottom plate 105 of the first frame 101, and fixed securely by screws or adhesion. The circuit board 8 is provided with a first interface 801 and a second interface 802, wherein the first interface 801 is a slot, a socket, or the like matched with the first connector 401 of the lamp strip 4. When the first connector 401 of the lamp strip 4 is inserted into the first interface 801, the electrical connection between the lamp strip 4 and the circuit board 8 is achieved. The second interface 802 is a standard interface for connecting an external power source, such as a DC power source interface or a USB interface, facilitating the fan to access the power source. A through hole can be provided on the shell to expose the second interface 802 to connect with the external power source.

[0055] The second light-emitting member 9 can be a high-brightness LED lamp bead, which is installed on the first frame 101 and corresponds to the center position of the rotating body 2 (the specific structure of the second light-emitting member 9 is not shown in the figure, only the installation position is indicated). The second light-emitting member 9 can be electrically connected to the circuit board 8 by welding or wire connection. When the fan is powered on, the current is transmitted to the circuit board 8 through the second interface 802, and the circuit board 8 allocates electric energy to the lamp strip 4 and the second light-emitting member 9 respectively. The lamp strip 4 is driven to achieve dynamic light effect display, and the second light-emitting member 9 continuously emits light to provide a central light source for the rotating body 2. For example, a bright light spot or light ring effect is formed at the center of the fan blade. The fan shell 1 can be provided with a laser-engraved inner mirror and an outer mirror corresponding to the position of the rotating body 2, and the second light-emitting member 9 realizes the thousand-layer mirror effect by reflection. The rotating body 2 can also be electrically connected to the circuit board 8, and the circuit board 8 simultaneously provides power for the rotation of the rotating body 2.

[0056] The circuit board 8 integrates the internal circuit connection of the fan, and through the design of the first interface 801 and the second interface 802, the orderly connection and power supply management of the lamp strip 4 and the external power source are achieved. The addition of the second light-emitting member 9 adds a new light effect element to the fan. In cooperation with the dynamic light effect of the lamp strip 4, a multi-level and diversified light effect combination is formed.

[0057] In some embodiments, the first interface 801 and the second interface 802 are arranged within the second area 104, and the annular mounting plate 106 is provided with an opening through which the circuit board 8 is connected to the second light-emitting member 9.

[0058] The circuit board 8 is laid on the bottom plate 105 of the first frame body 101, and the first interface 801 and the second interface 802 on the circuit board 8 are ensured to be located in the second area 104. The annular mounting plate 106 is processed by cutting or mold forming to have an opening with a size and shape suitable for the thickness and edge profile of the circuit board 8 to avoid the wiring of the circuit board 8. When the circuit board 8 is mounted, one end of the circuit board 8 is inserted through the opening of the annular mounting plate 106, so that the circuit board 8 can extend to the vicinity of the center position of the rotating body 2, thereby realizing electrical connection with the second light-emitting element 9.

[0059] By arranging the first interface 801 and the second interface 802 in the second area 104, such a layout can concentrate the connection lines of the lamp strip 4 and the power supply in the second area 104, avoid random wiring of the lines inside the fan, and effectively utilize the internal space of the fan. At the same time, the space of the rotating body 2 is avoided to be occupied, and the maximization of the diameter of the rotating body 2 is ensured. The centralized interface layout reduces the crossing and winding of the lines, reduces the risk of damage of the lines due to mutual friction and extrusion, and improves the reliability of the circuit connection.

[0060] In some embodiments, the outer surface of the side frame 108 of the second frame body 102 can be provided with a groove, and the groove can be used to embed a brand logo, a product model, an instruction diagram, or the like.
