Description

Technical Field

[0001] The utility model relates to the field of parallel fans, in particular to a parallel fan structure. Background Art

[0002] like Figure 1 As shown, in order to complete the parallel connection of more than two cooling fans and to avoid the need for users to connect wires in parallel, the prior art parallel fan structure 1 has utilized a terminal block 121 on the outer frame 111 of the fan 11 for docking design.

[0003] like Figure 1 As shown, the parallel fan structure 1 omits the wires and directly arranges the terminal seat 121 on the outer edge of the outer frame 111 of the fan 11 for docking. At this time, the user needs to hold the entire outer frame 111 of the fan 11 to operate the docking. In this way, the user's positioning and force application when matching the pins on the terminal seat 121 are not simple and inconvenient; at the same time, when the terminal seats 121 (such as the male terminal seat and the female terminal seat) are docked, the user is also required to overlap the terminal seats 121 with each other in the direction of docking to ensure correct and smooth splicing, which not only generates inefficiency in repeated attempts in operation, but also reduces the agility of the telecommunication connection between the parallel fans 11.

[0004] In addition, the terminal base 121 protruding from the outer frame 111 of the fan 11 will also hinder the flow of air, affect the flow field wind pressure and cause noise and other problems.

[0005] Therefore, how to solve the above problems and deficiencies is the direction that the utility model author of this case and related manufacturers engaged in this industry are eager to study and improve. Utility Model Content

DETAILED DESCRIPTION

[0028] The above-mentioned purpose and the structural and functional characteristics of the present invention will be described based on the preferred embodiments of the accompanying drawings.

[0029] See also Figure 2 This is a schematic diagram of the parallel fan structure of the utility model; Figure 3 It is a partial enlarged schematic diagram of a corresponding side of a fan of the utility model; Figure 4 It is a partial enlarged schematic diagram of the corresponding side of another fan of the utility model; Figure 5 It is a schematic diagram of the tenon of the parallel fan structure of the utility model; Figure 6 It is a partial cross-sectional schematic diagram of the parallel fan structure of the utility model; Figure 7 It is a partial enlarged schematic diagram of a corresponding side of a fan of another embodiment of the utility model; Figure 8 A schematic diagram of a tenon piece according to another embodiment of the utility model; Fig. 9 It is a schematic diagram of the mainboard wire group of the parallel fan structure of the utility model.

[0030] like Figure 2As shown, the parallel fan structure 2 of the utility model includes at least two fans 20. The two fans 20 each have an outer frame 21, and the outer frame 21 defines a space for accommodating a rotor, for example, in this embodiment, a space 22 for accommodating a fan wheel 221 is provided on an axis. Each side 211 of the outer frame 21 is formed with a groove 212, and a fan terminal seat 23 is provided in each groove 212 of the corresponding side 211 between the two fans 20. Figure 3 and Figure 4 As shown, the groove 212 is a long strip-shaped groove formed by being recessed on the side 211 of the outer frame 21 and has an arc-shaped wall inside.

[0031] And, if Figure 3 and Figure 4 As shown, the upper or lower end of the groove 212 also has an oblique opening 2121 respectively suitable for accommodating the fan terminal seat 23. In this figure, the fan terminal seat 23 is located in the oblique opening 2121 at the upper end of the groove 212. For example, a fan terminal seat 23 can be provided on the oblique opening 2121 of each groove 212, so that each fan terminal seat 23 is fixed to face the outer side of the opening of each groove 212. Furthermore, although the two fan terminal seats 23 are shown in this figure to be arranged in a symmetrical form, it is not limited to this. The two fan terminal seats 23 can also be arranged asymmetrically, for example, one fan terminal seat 23 is at the upper end of the groove 212, and the other fan terminal seat 23 is at the lower end of the groove 212.

[0032] Please refer to Figure 3 and Figure 4 The fan terminal seat 23 can be integrally formed with the outer frame 21 during the injection molding of the outer frame 21 and fixed in the bevel 2121; or the outer frame 21 is divided into an upper shell and a lower shell, and the fan terminal seat 23 is installed between the upper shell and the lower shell. Furthermore, each fan terminal seat 23 is connected to the fan circuit board (not shown) in the fan 20 via a wire set (not shown), a printed circuit board (PCB) or a flexible printed circuit board (FPC).

[0033] like Figure 2 , Figure 5 and Figure 6As shown, a tenon 3 has two sides 31 corresponding to the groove 212, and the fan terminal seats 23 in the groove 212 of the corresponding side 211 of the two fans 20 on the two sides 31 are respectively provided with a connector 33 for docking. Then, by utilizing the design of the modular tenon 3, each fan 20 can be docked and combined in a simple, fast and accurate splicing manner, so that the two fans 20 are arranged in parallel telecommunication connection between the corresponding sides 211 (for example, left and right). For example, the connector 33 can be formed on the surface by a wire penetrating through the two sides 31 of the tenon 3, so that the fan terminal seats 23 corresponding to the two fans 20 can transmit power and signals through the two connectors 33 for telecommunication connection embedded on the tenon 3.

[0034] Furthermore, the aforementioned fan terminal seat 23 is either a male terminal seat or a female terminal seat, and the connectors 33 are either a male end or a female end that matches the male terminal seat or the female terminal seat. For example, a fan terminal seat 23 disposed in the groove 212 of the corresponding side 211 of one fan 20 is a male terminal seat, and a fan terminal seat 23 disposed in the groove 212 of the corresponding side 211 of another fan 20 is a female terminal seat; or, the two fan terminal seats 23 disposed in the grooves 212 of the corresponding sides 211 of the two fans 20 are both male terminal seats or female terminal seats. Therefore, the connectors 33 on both sides 31 of the tenon 3 also need to be configured as male ends or female ends corresponding to the fans 20, or both are male ends or female ends. It is worth mentioning that when the two corresponding fan terminal seats 23 of the two fans 20 are respectively set as a male terminal seat and the other as a female terminal seat, it can also have an anti-mock effect, because the connector 33 must also cooperate with the different docking settings of the male terminal seat and the female terminal seat. Therefore, if the docking direction is wrong, the connector 33 and the fan terminal seats 23 on the two fans 20 will not be allowed to dock.

[0035] In summary, when parallel connection is performed, the modular tenon 3 can be set between two fans 20, and one side 31 of the tenon 3 is embedded in a groove 212 of one of the fans 20, and abuts against the bevel 2121 therein, so that the fan terminal seat 23 and the connector 33 are connected to each other; the other side 31 of the tenon 3 is correspondingly embedded in the groove 212 of the other fan 20, so that the two sides 31 of the tenon 3 are embedded between the two fans 20 and are completely covered and fixed by the two grooves 212. In this way, the two fans 20 are set in parallel telecommunication connection according to the corresponding side edges 211. For example, the volume of the tenon 3 is preferably smaller than the volume of the two fans 20, so that after being connected in parallel with the two fans 20, it is hidden in the groove 212 of the splicing side edges 211 of the two fans 20.

[0036] Furthermore, the parallel fan structure 2 of the present invention also allows the splicing of more than two fans 20 and more than one tenon 3. In other words, when the number of fans 20 is greater than two, as long as the corresponding side edges 211 between the two fans 20 are correspondingly embedded by a modular tenon 3, multiple fans 20 can be sequentially connected in parallel along the corresponding side edges 211 in a splicing manner as needed. Moreover, regardless of whether one side 31 of the tenon 3 in this embodiment has been embedded and docked with the groove 212 on any side edge 211 of one of the fans 20, the other side 31 that has not yet been docked can continue to be embedded with the corresponding side edge 211 of another fan 20 to continue the parallel connection. In this way, the multiple fans 20 of the parallel fan structure 2 of the present invention can be interconnected by means of the tenon 3 to achieve parallel power and signal transmission.

[0037] The present invention not only eliminates the need for wires, but the user only needs to connect the two sides 31 of each tenon 3 to the groove 212 between the two fans 20, and the assembly operation can be completed without holding the outer frame 21 of the entire fan 20, which not only makes installation easier, but also allows the groove 212 to guide the connector 33 and the fan terminal seat 23 to align and dock with each other, thereby completing the telecommunication connection between at least two or more fans 20 and the corresponding number of tenons 3, achieving the purpose of parallel transmission of power and signals, and reducing repeated attempts during the parallel assembly operation, making the operation faster.

[0038] Furthermore, because the utility model allows the user to utilize the modular tenons 3 and the grooves 212 of the two fans 20 to guide the splicing to complete the parallel connection, the parallel fan structure 2 of the utility model has no directionality, so the docking accuracy is even higher, which is more suitable for the needs of the increasingly developed electronic products.

[0039] Furthermore, the grooves 212 of the corresponding sides 211 of the two fans 20 are each provided with at least one limiting hole 25, and the two sides 31 of the tenon 3 are each provided with at least one convex buckle 35 that matches with the limiting hole 25. Thus, the limiting holes 25 and the convex buckles 35 are arranged in a concave-convex matching manner to detachably fasten the two fans 20 and the tenon 3, so that the fans 20 and the tenon 3 connected in parallel are less likely to be separated or dislocated due to external forces.

[0040] In addition, if Figure 7 and Figure 8 As shown, when the fan terminal seats 23 disposed in the grooves 212 of the corresponding sides 211 of the two fans 20 are both male terminal seats or female terminal seats, in order to prevent the tenon 3 from being connected in the wrong direction and causing damage, a foolproof groove 36 (such as Fig. 9 ), and an anti-fool strip 26 (as shown) disposed on one of the grooves 212 of the corresponding side edges 211 of the two fans 20. Figure 8 Specifically, the foolproof groove 36 can be extended from the outer end of the side surface of one side 31 of the tenon piece 3 and is not connected to the other side 31, and can be inserted from the opening of the groove 212 during docking to form a convex-concave matching structure of a tenon type.

[0041] like Fig. 9 Please refer to Figure 3 , Figure 4 and Figure 6 , the groove 212 of the other side 211 of at least one of the two fans 20 is also provided with another fan terminal seat 23. The utility model can further include a motherboard wire assembly 4, which has a tenon 41, and the front end 411 of the tenon 41 is provided with a connector 33 to connect to the other fan terminal seat 23. The rear end 413 of the tenon 41 is provided with a row of wires 43, and the end of the row of wires 43 is provided with a row of wires terminal seat 44 for connecting to the host circuit board (not shown). In this way, the parallel fan structure 2 of the utility model is connected to the host circuit board through the motherboard wire assembly 4 to achieve telecommunication connection, thereby obtaining power supply and signal transmission. Furthermore, the groove 212 of the other side 211 of one of the two fans 20 is also provided with the limiting hole 25, and the tenon 41 is also provided with at least one conductive protrusion 45 to cooperate with the limiting hole 25 of the groove 212, so that the fan 20 and the motherboard conductive assembly 4 will not be separated or dislocated by external force.

[0042] The above description has been a detailed description of the utility model, and the above description is only a preferred embodiment of the utility model, which should not limit the scope of implementation of the utility model. That is, all equivalent changes and modifications made based on the utility model should still fall within the scope of the patent coverage of the utility model.
