Description

Technical Field

[0001] This utility model relates to the field of cooling fan technology, specifically to a cooling fan that can be spliced ​​and stacked. Background Technology

[0002] The splicing structure of a cooling fan mainly refers to the connection or assembly method between individual fans, ensuring that the fans can operate stably and dissipate heat effectively. Splicing multiple cooling fans together is mainly to enhance the heat dissipation effect and increase the heat dissipation area.

[0003] Regarding the splicing structure of cooling fans, the authorized announcement number CN222351000U discloses a splicing structure for cooling fans, which specifically discloses a cooling fan body including two or more sets of cooling fan bodies. The adjacent cooling fan bodies are connected by splicing clips. The cooling fan bodies have snap-fit ​​slots on opposite sides. The two ends of the splicing clips are respectively snapped into the snap-fit ​​slots of two adjacent cooling fans. When one end of the splicing clip is snapped into one of its snap-fit ​​slots, the other end can rotate around the snap-fit ​​point as the axis and snap into the other snap-fit ​​slot. The inner wall of the snap-fit ​​slot is provided with a circular locking groove. The splicing clip (extending to one side of the snap-fit ​​slot with a snap-fit ​​ear, the end of the snap-fit ​​ear having a locking block corresponding to the locking groove; when the locking block at one end of the splicing clip is engaged in the locking groove, the other end can rotate around the snap-fit ​​point as an axis) is provided. A wiring groove for cable routing is provided between the snap-fit ​​slots on opposite sides of the cooling fan body. Two adjacent cooling fan bodies are electrically connected by cables, and the connection terminals of the cables are located at the snap-fit ​​slots.

[0004] However, the aforementioned cooling fan splicing structure still has some drawbacks. For example, although adjacent cooling fan bodies are connected using splicing clips, this splicing method is still not convenient to use. Furthermore, external wiring is required for electrical connection between adjacent cooling fan bodies, which is also cumbersome. Therefore, improvements to the existing technology are needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a heat dissipation fan that can be spliced ​​and stacked, which does not require separate splicing clips and external wiring to splice two heat dissipation fan bodies, thus making it convenient to use and improving assembly efficiency. Moreover, this splicing structure is relatively simple.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A stackable cooling fan includes a cooling fan body. Each cooling fan body comprises a hollow shell, a fan installed within the shell, a male connector pin and a female connector seat located on the left and right sides of the shell and electrically connected to the fan, two first engaging protrusions located on one side of the shell and protruding outwards, and two first engaging grooves located on the other side of the shell. The male connector pin is located in a first clearance groove on one side of the shell. The two first engaging protrusions are vertically distributed on the upper and lower sides of the first clearance groove, with their outer ends protruding from the male connector pin. The female connector seat is located in a second clearance groove on the other side of the shell. The two first engaging grooves are vertically distributed on the upper and lower sides of the second clearance groove. The cooling fan bodies can be connected via corresponding male connector pins and female connector seats. After connection, the two first engaging protrusions are respectively engaged in the two first engaging grooves to form a positioning structure. This design facilitates the assembly of cooling fan bodies.

[0008] It also includes the following technical solutions:

[0009] Furthermore, the cooling fan body also includes two second engaging protrusions and two second engaging grooves located on the left and right sides of the housing, respectively; the two first engaging protrusions and the two second engaging protrusions are distributed along the length direction of the side of the housing; the two first engaging grooves and the two second engaging grooves are distributed along the length direction of the side of the housing, respectively; after the two cooling fan bodies are engaged, the two first engaging protrusions can be respectively engaged in the two first engaging grooves and the two second engaging protrusions can also be respectively engaged in the two second engaging grooves to form a positioning structure. This configuration improves the stability between the cooling fan bodies.

[0010] Furthermore, both the first and second snap-fit ​​protrusions are L-shaped; the first ends of the two first snap-fit ​​protrusions are respectively connected to the housing, and the second ends are arranged opposite or back to each other; the first ends of the two second snap-fit ​​protrusions are respectively connected to the housing, and the second ends are arranged opposite or back to each other; the two first and two second snap-fit ​​grooves respectively mate with the second ends of the two first and two second snap-fit ​​protrusions. This configuration ensures the stability of the cooling fan body.

[0011] Furthermore, a first baffle that mates with the first snap-fit ​​protrusion is provided on one side of each of the two first snap-fit ​​grooves at one end of the groove, so that the second end of the first snap-fit ​​protrusion can be blocked by the first baffle after being inserted into one end of the first snap-fit ​​groove; a second baffle corresponding to the second snap-fit ​​protrusion is provided on one side of each of the two second snap-fit ​​grooves at one end of the groove, so that the second end of the second snap-fit ​​protrusion can be blocked by the second baffle after being inserted into one end of the second snap-fit ​​groove. This arrangement improves the stability between the cooling fan bodies.

[0012] Furthermore, the second ends of the two first snap-fit ​​protrusions are arranged opposite each other; the second ends of the two second snap-fit ​​protrusions are arranged opposite each other; the two first baffles are respectively located on the upper and lower sides of one end of the two first snap-fit ​​grooves; the two second baffles are respectively located on the lower and upper sides of one end of the two second snap-fit ​​grooves.

[0013] Furthermore, each of the cooling fan bodies also includes a light strip installed in the housing that can emit light outwards; the light strip is electrically connected to the male connector, the female connector, and the fan, respectively. The light strip can be used to provide colorful lighting to create a better atmosphere.

[0014] Furthermore, the light strip is arranged around the fan so that the light from the light strip is projected outwards.

[0015] Furthermore, the housing includes light-transmitting plates located on both sides thereon, so that the light from the light strip can be emitted outward.

[0016] Furthermore, the male connector and the female connector are respectively disposed on the light strip.

[0017] Furthermore, the depths of the two first snap-fit ​​grooves are respectively greater than the depths of the second clearance grooves.

[0018] The beneficial effects of this utility model are as follows:

[0019] When connecting two cooling fan bodies, this invention only requires connecting the male connector to the female connector, and then using the first snap-fit ​​protrusion directly provided on the housing to engage with the first snap-fit ​​groove. This allows the first snap-fit ​​protrusion to be positioned within the first snap-fit ​​groove. The two first snap-fit ​​grooves then limit the position of the first snap-fit ​​protrusion, thus securing the two first snap-fit ​​protrusions, the male connector, and the female connector, achieving the splicing and stacking of the two cooling fan bodies. This design eliminates the need for separate splicing clips and external wiring to connect the two cooling fan bodies, simplifying use, improving assembly efficiency, and providing a relatively simple splicing structure.

[0020] In addition, since the outer end of the first snap-fit ​​protrusion protrudes from the male connector pin, when the cooling fan body falls, the first snap-fit ​​protrusion can make contact with the ground first, thus preventing the terminal in the male connector pin from directly contacting the ground, so as to avoid bending or wear of the terminal. In other words, the first snap-fit ​​protrusion can be used to protect the male connector pin. Attached Figure Description

[0031] The specific implementation methods according to this disclosure are described below with reference to the accompanying drawings.

[0032] like Figures 1-8 As shown, a stackable cooling fan includes a cooling fan body 100.

[0033] The cooling fan body 100 includes a hollow housing 1, a fan 2 installed in the housing 1, male connector pins 3 and female connector seats 4 located on the left and right sides of the housing 1 and electrically connected to the fan 2, two first snap-fit ​​protrusions 5 located on one side of the housing 1 and protruding outwards, and two first snap-fit ​​grooves 6 located on the other side of the housing 1. The fan 2 includes a motor installed on the housing and fan blades installed on the output shaft of the motor.

[0034] The male connector 3 is located in the first clearance groove 7 on one side of the housing 1; the two first snap-fit ​​protrusions 5 are distributed vertically on the upper and lower sides of the first clearance groove 7 respectively, and their outer ends protrude from the male connector 3 respectively.

[0035] The female connector 4 is located in the second clearance groove 8 on the other side of the housing 1; the two first snap-fit ​​grooves 6 are distributed vertically on the upper and lower sides of the second clearance groove 8 respectively.

[0036] During use, the cooling fan bodies 100 can be connected to the female connectors 4 via corresponding male connectors 3. After connection, the two first snap-fit ​​protrusions 5 are respectively engaged in the two first snap-fit ​​grooves 6 to form a positioning structure. It should be noted that if the heat dissipation efficiency is sufficient, it is also possible to use only one cooling fan body 100.

[0037] In summary, when connecting two cooling fan bodies 100, this invention only requires connecting the male connector 3 to the female connector 4, and then using the first snap-fit ​​protrusion 5 directly provided on the housing 1 to cooperate with the first snap-fit ​​groove 6, so that the first snap-fit ​​protrusion 5 can be positioned in the first snap-fit ​​groove 6. In this way, the two first snap-fit ​​grooves 6 can limit the position of the first snap-fit ​​protrusion 5, thereby completing the fixation of the two first snap-fit ​​protrusions 5, the male connector 3 and the female connector 4, and thus achieving the splicing and stacking of the two cooling fan bodies 100. Therefore, the design of this invention does not require separate splicing clips and external wiring to splice the two cooling fan bodies 100, which facilitates use, improves assembly efficiency, and the splicing structure is relatively simple. In addition, since the outer end of the first snap-fit ​​protrusion 5 protrudes from the male connector pin 3, when the cooling fan body 100 falls, the first snap-fit ​​protrusion 5 can make contact with the ground first, thus avoiding the terminals in the male connector pin 3 from directly contacting the ground, so as to prevent the terminals from bending or wearing. In other words, the first snap-fit ​​protrusion 5 can be used to protect the male connector pin 3.

[0038] like Figures 1-4 as well as Figure 7 and Figure 8As shown, in this embodiment, to improve stability, the cooling fan body 100 further includes two second snap-fit ​​protrusions 9 and two second snap-fit ​​grooves 10 respectively installed on the left and right sides of the housing 1; the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9 are distributed along the length direction of the side of the housing 1; the two first snap-fit ​​grooves 6 and the two second snap-fit ​​grooves 10 are distributed along the length direction of the side of the housing 1; after two adjacent cooling fan bodies 100 are snapped together, the two first snap-fit ​​protrusions 5 are respectively snapped into the two first snap-fit ​​grooves 6 and the two second snap-fit ​​protrusions 9 are also respectively snapped into the two second snap-fit ​​grooves 10 to form a positioning structure. Therefore, through the above arrangement, the stability between the cooling fan bodies 100 can be further improved by utilizing the cooperation of the second snap-fit ​​protrusions 9 and the second snap-fit ​​grooves 10, making them less prone to loosening.

[0039] like Figures 1-4 as well as Figure 7 and Figure 8 As shown, preferably, both first snap-fit ​​protrusions 5 and both second snap-fit ​​protrusions 9 are L-shaped; the first ends of the two first snap-fit ​​protrusions 5 are respectively connected to the housing 1, and the second ends are arranged opposite to or away from each other; the first ends of the two second snap-fit ​​protrusions 9 are respectively connected to the housing 1, and the second ends are arranged opposite to or away from each other. The two first snap-fit ​​grooves 6 and the two second snap-fit ​​grooves 10 respectively mate with the second ends of the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9. This arrangement allows the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9 to properly mate with the two first snap-fit ​​grooves 6 and the two second snap-fit ​​grooves 10, ensuring the stability of the cooling fan body 100.

[0040] like Figures 1-4 as well as Figure 7 and Figure 8 As shown, specifically, a first baffle 11 is provided on one side of each of the two first snap-fit ​​grooves 6 at one end of the groove, which cooperates with the first snap-fit ​​protrusion 5, so that the second end of the first snap-fit ​​protrusion 5 can be blocked by the first baffle 11 after being inserted into one end of the first snap-fit ​​groove 6; a second baffle 12 is provided on one side of each of the two second snap-fit ​​grooves 10 at one end of the groove, which corresponds to the second snap-fit ​​protrusion 9, so that the second end of the second snap-fit ​​protrusion 9 can be blocked by the second baffle 12 after being inserted into one end of the second snap-fit ​​groove 10. Therefore, by setting the first baffle 11 and the second baffle 12, the first snap-fit ​​protrusion 5 and the second snap-fit ​​protrusion 10 can be effectively limited to prevent the cooling fan body 100 from becoming loose after installation. Specifically, the first snap-fit ​​protrusion 5 and the second snap-fit ​​protrusion 9 can be connected to their respective snap-fit ​​grooves by an interference fit to prevent the snap-fit ​​protrusions from becoming loose.

[0041] likeFigures 1-4 as well as Figure 7 and Figure 8 As shown, in this embodiment, the second ends of the two first engaging protrusions 5 are arranged opposite to each other, that is, the second end of the upper first engaging protrusion 5 extends upward, while the second end of the lower first engaging protrusion 5 extends downward; the second ends of the two second engaging protrusions 9 are arranged opposite to each other, that is, the second end of the upper second engaging protrusion 9 extends downward, while the second end of the upper second engaging protrusion 9 extends upward; the two first baffles 11 are respectively located on the upper and lower sides of one end of the two first engaging grooves 6; the two second baffles 12 are respectively located on the lower and upper sides of one end of the two second engaging grooves 10. However, those skilled in the art should know that the orientation of the second ends of the two first engaging protrusions 5 and the second ends of the two second engaging protrusions 9 can be combined in different ways according to actual needs, and no further examples will be given here.

[0042] like Figure 5 as well as Figure 5 and Figure 5 As shown, preferably, the depths of the two first engaging grooves 6 are greater than the depth of the second clearance grooves 8, thereby allowing the first engaging protrusion 5 to more easily align with the first engaging grooves 6 and reducing the likelihood of misalignment. Furthermore, the depths of the first engaging grooves 6 and the second engaging grooves 10 are equal, enabling more synchronized insertion of the first engaging protrusion 5 and the second engaging protrusion 6. Moreover, the two first engaging grooves 6 are respectively connected to the second clearance grooves 8.

[0043] like Figure 5 As shown, preferably, each cooling fan body 100 also includes an LED strip 13 installed in the housing 1 and capable of emitting light outwards; the LED strip 13 is electrically connected to the male connector 3, the female connector 4, and the fan 2 respectively. Therefore, by providing the LED strip 13, it is possible to provide colorful lighting to create a better atmosphere.

[0044] like ​ As shown, in this embodiment, the light strip 13 is arranged around the fan 2, which allows for better light emission.

[0045] like ​ As shown, in this embodiment, the housing 1 includes light-transmitting plates 14 located on both sides thereon, so that the light from the light strip 13 can be emitted outwards. However, those skilled in the art should know that the light-transmitting plates 14 can also be set in other positions on the housing 1, and no further examples will be given here.

[0046] like ​ As shown, in this embodiment, the male connector 3 and the female connector 4 are respectively disposed on the light strip 13.

[0047] The following describes the specific working principle of this utility model in order to help you understand it:

[0048] First, align the male connector 3 and female connector 4 of the two cooling fan bodies 100. Next, insert the male connector 3 into one end of the second clearance groove 8, and simultaneously insert the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9 into one end of the two first snap-fit ​​grooves 6 and the two second snap-fit ​​grooves 10, respectively. Next, push the male connector 3 into the female connector 4 until the terminals of the male connector 3 are properly inserted into the female connector 4. Simultaneously, the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9 are also inserted into their respective preset positions. At this point, the two first snap-fit ​​protrusions 5 and the two second snap-fit ​​protrusions 9 are blocked by the two first baffles 11 and the second baffle 12, thus creating a limiting effect. These steps complete the splicing and stacking of the two cooling fan bodies 100. If it is necessary to splice other cooling fan bodies 100, simply repeat the above steps.

[0049] The scope of this utility model is not defined by the embodiments described above, but by the appended claims and their equivalents.
