Description

Parallel-type luminous fan

This invention relates to the structure of a computer fan, and more particularly to a parallel-type luminous fan that allows multiple identical luminous fans to be quickly connected together.

Approved Republic of China Utility Model Certificate No. M580203 discloses a "multi-unit connectable computer light-emitting fan," comprising a main body with a fan blade at its center. A light-emitting area is located on at least two sides of the fan blade at the top of the main body. A power socket and a first connector are located on one side of the main body, and a second connector is located on the other side. The power socket is electrically connected to the first connector, the second connector, the fan blade, and the light-emitting areas. When the power socket on one side of the main body is plugged in, it drives the fan blade to rotate and the light-emitting area to emit light. Furthermore, when the first connector of one main body is connected to the second connector of another main body, it drives the fan blade of that other main body to rotate and the light-emitting area to emit light.

In the aforementioned known technologies, both the first and second connectors are fixedly mounted on the fan body. After a period of use, these connectors are prone to electrode oxidation or wear, leading to poor contact or malfunction. In such cases, the entire computer LED fan must be replaced or discarded, affecting its lifespan and causing waste.

The Republic of China Utility Model Certificate No. M635856 discloses a "light-emitting fan connection structure," which includes a plurality of light-emitting fans and an external connector. The light-emitting fans are arranged adjacent to each other in parallel. The fan blades of the light-emitting fans are set in a frame, and a light guide ring is combined with a light-emitting module and arranged around the fan blades. The frame is provided with a fan circuit board and a fastening part. The fan circuit board is electrically connected to the fan blades and the light-emitting module. The external connector includes a base and a connection circuit board. The base includes a pair of latches, and the connection circuit board includes first and second conductive pins. The base is positioned between adjacent LED fans, and the latches engage with the latching parts of adjacent LED fans, thereby electrically connecting the first conductive pin to the fan circuit board and the second conductive pin to the other fan circuit board. This reduces cable management complexity and improves ease of use. In addition to transmitting power, the external connector of the LED fan connection structure described above (M635856) also works in conjunction with the latch to connect two adjacent LED fans in parallel.

The main components used to connect two adjacent LED fans are only a pair of hooks on the external connector base and a latch, which also has hooks. These hooks engage the adjacent LED fans, resulting in a weak structure. Furthermore, the external connector base and latch lack a well-designed and force-applying structure; disassembly requires a screwdriver or other tools, making it extremely inconvenient to use and operate.

The technical problem this invention aims to solve is to provide a parallel-type luminous fan that allows for the convenient and quick parallel connection of several identical parallel-type luminous fans, enabling simultaneous electrical connection between the connected fans without easy loosening.

A preferred embodiment of the parallel-type luminous fan of the present invention includes:

The button and circuit board are housed together in the housing. The back cover is mounted at the bottom of the housing to encapsulate the button and circuit board within the housing. The second and third electrodes of the circuit board are exposed through the back cover to contact the first electrode of the outer frame.

The back of the button has a retaining clip extending along the insertion/removal direction. A movable jaw can clamp the retaining clip to hold the button in the active position, thereby securing the pluggable electrical connector in the connector slot. The movable jaw can release the retaining clip, allowing the button to be pushed back to the release position by the spring force, thus allowing the pluggable electrical connector to be removed from the connector slot.

Preferably, the button has two parallel latches that interact with corresponding push-button latches when the two identical outer frames are joined together.

Preferably, the key includes: a keycap, the top of which passes through an opening at the top of the housing, and the key is free to move in the insertion/removal direction.

In the embodiments disclosed in this invention's specification and drawings, the directions (e.g., up, down, left, right, front, and back) mentioned are based on the content shown in the drawings and are used to illustrate the relative relationships (e.g., positional relationships, connection relationships, and operational relationships) between the various elements or structures in the embodiments. In principle, the stated directions are appropriate when the positions of the elements or structures mentioned in this invention's specification correspond to those shown in the drawings. If the positions of the elements or structures mentioned in this invention's specification change, the stated directions should also be changed accordingly.

Please refer to Figures 1 and 2, which are schematic diagrams and exploded views of the structure of a first embodiment of the parallel-type luminous fan of the present invention. The present invention proposes a structure for a parallel-type luminous fan capable of connecting two identical luminous fans side-by-side. For ease of understanding and explanation, Figures 1 and 2 exemplarily illustrate two identical parallel-type luminous fans with the same structure, wherein the outer frame 10 of the first parallel-type luminous fan F1 and the outer frame 10 of the second parallel-type luminous fan F2 are connected side-by-side.

A preferred embodiment of the parallel-type luminous fan of the present invention includes: an outer frame 10, a motor 20 and a fan blade 21 connected to the output shaft of the motor 20, a pluggable electrical connector 50, and a luminous element 30.

At each corner of the same side of the outer frame 10, a slot 11 is provided. The slot 11 is recessed into the outer frame 10, facing towards its center. The slot 11 is defined by a bottom surface 110, two parallel side walls 111 and 112, and a back surface 113. Preferably, the slot 11 has two notches A1 and A2 in different directions. A pluggable electrical connector 50 can be inserted into or removed from the slot 11 through notch A1 along a plugging/removing direction D. Notch A2 faces the notch A2 of another slot 11 in the outer frame 10 to be connected. The structures of the two slots 11 at each corner of the same side of the same outer frame 10 are symmetrical.

Each slot 11 has several first electrodes 12 on its bottom surface 110 (see enlarged view in Figure 8). Each slot has a first guide rail 13 on each side wall 111, 112. When two identical outer frames 10 are connected side-by-side, the two adjacent slots 11 on the two outer frames 10 together form a connecting slot P (see Figure 3). The first electrodes 12 of the slots 11 on the same outer frame 10 are electrically connected one-to-one, meaning that the first electrodes 12 of the slots 11 on the same outer frame 10 will have the same electrical characteristics. This ensures that when two or more parallel-type LED fans are connected in parallel, the power supply or control signal can be transmitted equally to each parallel-type LED fan.

In another preferred embodiment of the parallel-type light-emitting fan of the present invention, a first magnetic element 41 is disposed on one side of the outer frame 10 for connecting another light-emitting fan, and a second magnetic element 42, which can be matched with the first magnetic element 41, is disposed on the opposite side of the outer frame 10; in a preferred embodiment, the first magnetic element 41 and the second magnetic element 42 are disposed inside the outer frame 10; in a preferred embodiment, the first magnetic element 41 and the second magnetic element 42 are magnets that can attract each other; in another preferred embodiment, the first magnetic element 41 is a magnet and the second magnetic element 42 is an iron sheet; in yet another preferred embodiment, the first magnetic element 41 is an iron sheet and the second magnetic element 42 is a magnet.

In a preferred embodiment, a first positioning element 43 is disposed on one side of the outer frame 10 for connecting another light-emitting fan, and a second positioning element 44, which matches the first positioning element 43, is disposed on the opposite side of the outer frame 10. In a preferred embodiment, the first positioning element 43 is a protruding protrusion, and the second positioning element 44 is a groove that can couple with the first positioning element 43. Through the mutual magnetic attraction of the first magnetic element 41 and the second magnetic element 42, and with the assistance of the first positioning element 43 and the second positioning element 44, the connection of two identical parallel-type light-emitting fans can be completed more accurately and quickly.

In a preferred embodiment of the invention, a motor 20 is disposed at the center of the outer frame 10, and fan blades 21 are connected to the output shaft of the motor 20. The motor 20 is electrically connected to the first electrode 12 of one of a plurality of slots 11 to obtain power.

The pluggable electrical connector 50 functions as follows: (1) as one of the connecting components structurally connecting two parallel outer frames 10; (2) as a connection component for power supply and control signals of two or more parallel-connected LED fans; and (3) as a power connection component between the two or more parallel-connected LED fans and an external power supply.

To achieve the above-mentioned functions, a preferred embodiment of the pluggable electrical connector 50 includes at least: a housing 51 and a circuit board 52 disposed within the housing 51; the housing 51 is provided with a third guide rail 511, and the circuit board 52 includes: a plurality of second electrodes 53 and a plurality of third electrodes 54, the second electrodes 53 and the third electrodes 54 being electrically connected to each other in a one-to-one manner (e.g., electrically connected to each other through printed circuits arranged on the circuit board 52); in a preferred embodiment, the shape of the housing 51 matches the connector slot P, and the housing 51 is pluggably disposed in the connector slot P, so the pluggable electrical connector 50 can be inserted into the connector slot P or removed from it along the insertion/removal direction D. After the connector slot P is pulled out (see Figure 3), and the pluggable electrical connector 50 is inserted into the connector slot P, the second electrodes 53 contact the first electrodes 12 of one of the two adjacent outer frames 10 (e.g., the first electrode 12 of the right outer frame 10 in Figure 6), and the third electrodes 54 contact the first electrodes 12 of the other of the two adjacent outer frames 10 (e.g., the first electrode 12 of the left outer frame 10 in Figure 6). At the same time, the third rail 511 can be coupled with the first rails 13 of the connector slot P (see Figure 3), thereby connecting the two identical adjacent outer frames 10 together and completing the electrical connection of power supply and control signals. In a preferred embodiment, the first guide rail 13 is an elongated straight component protruding from the two side walls 111, 112 of the slot 11, and the third guide rail 511 is an elongated straight groove on the outer surface of the housing 51.

The light-emitting element 30 is electrically connected to one of the first electrode 12, the second electrode 53, and the third electrode 54, so that the light-emitting element 30 can obtain external power through one of the first electrode 12, the second electrode 53, and the third electrode 54. A preferred embodiment of the light-emitting element 30 is a light-emitting diode (LED) or a small liquid crystal panel (LCD), wherein another preferred embodiment of the light-emitting element 30 is a monochromatic light-emitting diode or a multicolor light-emitting diode.

In a preferred embodiment of the present invention, the pluggable electrical connector 50 further includes a push-button switch 60. The push-button switch 60 functions to: secure the pluggable electrical connector 50 to the connector slot P to prevent it from loosening, and to release the securing of the pluggable electrical connector 50 so that the pluggable electrical connector 50 can be pulled out of the connector slot P. Referring to Figures 6 and 7, the push-button switch 60 comprises: a button 61, a spring 62, a back cover 63, and a push-button latch 64. The button 61 is slidably disposed on the housing 51, and the button 61 can reciprocate along the insertion/removal direction D to an active position (see Figure 5-1). The button 61 has a release position (see Figure 5-2). A spring 62 is disposed between the back of the button 61 and the back cover 63. The spring 62 provides a force to push the button 61 back to the release position in its extended state. The button 61 and the circuit board 52 are housed together in the housing 51. The back cover 63 is mounted at the bottom of the housing 51 (e.g., the back cover 63 is detachably mounted at the bottom of the housing 51 by a barb 631) to enclose the button 61 and the circuit board 52 within the housing 51. The second electrode 53 and the third electrode 54 of the circuit board 52 are exposed through the back cover 63 to contact the first electrode 12 of the frame 10 (see Figure 6).

A push-button latch 64 is located at the bottom of the slot 11 of the outer frame 10. The push-button latch 64 has a movable claw 641 (see Figures 6 and 8). The movable claw 641 is used to clamp the button 61 when it has moved to the active position, thereby securing the pluggable electrical connector 50 in the connector slot P to prevent it from loosening. Conversely, the movable claw 641 can also release the button 61, allowing the button 61 to be pushed back to the release position under the elastic force of the spring 62, thereby allowing the pluggable electrical connector 50 to be pulled out of the connector slot P.

The back of the key 61 has a latch 611 extending along the insertion/removal direction D. In a preferred embodiment, the key 61 has two parallel latches 611 (see Figure 7), which can interact with two corresponding push-button latches 64 respectively. A preferred embodiment of the key 61 includes a keycap 612, the top of which passes through an opening 512 at the top of the housing 51, and the key 61 is freely movable along the insertion/removal direction D. The keycap 612 has a protruding stop 613 around its periphery, which can interfere with the outer edge of the opening 512 of the housing 51 to prevent the key 61 from dislodging from the housing 51.

When the normally pluggable electrical connector 50 is not inserted into the connector slot P, button 61 is in the released position (see Figure 3). When the pluggable electrical connector 580 is inserted into the connector slot P (see Figure 4), the keycap 612 can be used to push the button 61 to the activated position. The front end of the latch 611 of button 61 will push the movable claw 641, and thus be clamped by the movable claw 641 and held in the activated position (see Figure 4). 5-1) This secures the pluggable electrical connector 50 in the connector slot P to prevent it from loosening; press the keycap 612 of the key 61 again and push the movable jaw 641 by the latch 611. The movable jaw 641 will release the latch 611 of the key 61 (see Figure 5-2), allowing the key to be pushed back to the release position by the spring force, thus allowing the pluggable electrical connector to be pulled out of the connector slot.

In a preferred embodiment, the light-emitting element 30 is a light-emitting diode and is disposed on the circuit board 52. The front of the keycap 612 of the key 61 has a light-transmitting portion 614, through which light generated by the light-emitting diode can pass. A preferred embodiment of the light-transmitting portion 614 is a perforation, which can be presented in the form of text or graphics, thereby providing a visual effect of illuminated text or graphics on the keycap 612 (see Figure 2).

In another preferred embodiment, the light-emitting element 30 is a small liquid crystal panel (LCD) disposed on the side of the outer frame 10 (see Figure 1). The small LCD is electrically connected to the first electrode 12, thereby providing a combined light-emitting and image-emitting effect.

In a preferred embodiment of the present invention, at least one pluggable electrical connector 50 is configured with an external power cable 70 (see Figure 1). One end of the external power cable 70 is electrically connected to a second electrode 53 or a third electrode 54, and the other end of the external power cable 70 is electrically connected to a power connector 71 (e.g., a USB connector or an XH2.54 terminal block) for electrically connecting to an external power source (e.g., a fan connector on a computer motherboard for controlling an external cooling fan). In other preferred embodiments, the power connector 71 is an electrical connector that includes RGB (red, green, and blue LED) contacts and pulse width modulation (PWM) contacts for electrically connecting to the light-emitting diode's light signal controller and the motor 20's PWM speed controller. In a preferred embodiment, when two identical parallel-type luminous fans are connected to each other via the outer frame 10, the first pluggable electrical connector 50 of the first parallel-type luminous fan F1 is equipped with an external power cord 70 for electrically connecting to an external power source and/or control signal; in another preferred embodiment, a pluggable electrical connector 50 as a terminal can also be inserted into the last slot 11 of the second parallel-type luminous fan F2.

In a preferred embodiment, the first pluggable electrical connector 50 for electrically connecting to an external power source, and the pluggable electrical connector 50 located at the last slot 11 as an end, have only half the external shape (see Figure 2). In other words, the shapes of the first pluggable electrical connector 50 and the last pluggable electrical connector 50 are flush with the outer frame 10, so that the parallel-type luminous fan can have a complete appearance.

In a preferred embodiment, each slot 11 has corresponding through holes 72 on its two side walls 111, 112, and on the housing 51 of the pluggable electrical connector 50 into which the connecting slot P is inserted, allowing bolts to pass through the through holes 72 to install the parallel-type luminous fan in a predetermined position (e.g., a computer case).

In a preferred embodiment, the number of the first electrode 12, the second electrode 53, and the third electrode 54 is determined by the actual application. In principle, the number of the first electrode 12, the second electrode 53, and the third electrode 54 should be sufficient to provide the power required for the electrical connection between the motor 20 and the light-emitting element 30. If necessary, the first electrode 12, the second electrode 53, and the third electrode 54 can also be provided for electrically connecting control signals, such as motor speed control signals, or control signals for the light-emitting element 30, to control the light-emitting element 30 to produce dynamic light emission effects, different colors of light, and LCD image signals.

As shown in Figures 8 and 9, in a preferred embodiment of the present invention, the outer frame 10 of the parallel-type light-emitting fan is rectangular in shape. The slots 11 can be configured on both parallel sides of the outer frame 10; in other words, slots 11 are configured at all four corners of the rectangular outer frame 10. For several slots 11 configured in the same parallel-type light-emitting fan, the first electrodes 12 of the several slots 11 only need to be electrically connected to each other in a one-to-one manner through wiring (i.e., wires) provided inside the outer frame 10. The first electrodes 12 of these several slots 11 only need to share one external power cord 70 and power connector 71 to obtain external power.

By using the pluggable electrical connector 50 to connect two (see Figure 1), three (see Figure 10), or more parallel-type luminous fan frames 10 together, a luminous effect can be provided around the perimeter of the parallel-type luminous fan frame 10, and the connection of multiple parallel-type luminous fan frames 10 can be made more reliable.

Although the present invention has been disclosed above through the aforementioned embodiments, it is not intended to limit the invention. Anyone skilled in similar arts may make modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of patent protection for this invention shall be determined by the claims attached to this specification.

The movable jaw can release the retaining clip, allowing the button to be pushed back to the release position under the spring force, thus enabling the pluggable electrical connector to be removed from the connector slot. As described in claim 8, the button in the parallel-type luminous fan has two parallel latches that interact with corresponding push-button latches when the two identical outer frames are joined together. As described in claim 8, the button in the parallel-type luminous fan comprises: a keycap, the top of which extends through an opening at the top of the housing, and the button being freely movable in the insertion/removal direction; the keycap having a protruding stop around its periphery, the stop interfering with the outer edge of the opening in the housing to prevent the button from dislodging from the housing. As described in claim 10, in the parallel-type luminous fan, the luminous element is a light-emitting diode (LED), which is disposed on the circuit board and electrically connected to one of the second and third electrodes. The front of the keycap has a light-transmitting portion, allowing light generated by the LED to pass through. As described in claim 11, the parallel-type luminous fan has a light-transmitting portion that is a perforation, the perforation being presented in the form of text or graphics, and the luminous diode being a monochromatic luminous diode or a polychromatic luminous diode. As described in claim 1, in the parallel-type light-emitting fan, the light-emitting element is a small liquid crystal panel, which is disposed on the side of the outer frame and electrically connected to the first electrode. As described in claim 1, in a parallel-type luminous fan, at least one of the pluggable electrical connectors is equipped with an external power cord, one end of which is electrically connected to the second or third electrode, and the other end of which is electrically connected to a power connector. As described in claim 14, the parallel-type luminous fan has a rectangular outer frame. Slots are located at the corners of two parallel sides of the outer frame. These slots in the same parallel-type luminous fan are electrically connected one-to-one to each other via wiring inside the outer frame. Furthermore, the first electrodes of these slots share a single external power cable and power connector. As described in claim 1, in the parallel-type luminous fan, the two side walls of the slot and the housing of the pluggable electrical connector into which the slot is inserted are each provided with corresponding through holes.
