[0067] In this embodiment and some embodiments, the fastening groove 111 may have two guide slopes 111a facing the fastening member 300, and the fastening member 300 may have two guide slopes 301 facing the fastening groove 111, so that the fastening member 300 can be more smoothly positioned in the fastening groove 111 by being guided by the guide slopes 111a and the guide slopes 301. However, the present invention is not limited to the configuration and number of guide slopes 111a and 301. In other embodiments, there may be no guide slope configuration, or the fastening groove and the fastening member may have only one guide slope, or only one of the fastening groove and the fastening member may have a guide slope.

[0068] In this embodiment and some embodiments, the fastening member 300 may include a base 310, two side arms 320, and two hooks 330. The side arms 320 are respectively connected to opposite sides of the base 310. The hooks 330 are respectively connected to the side of the side arms 320 away from the base 310, and each hook has the aforementioned guide slope 310. By configuring the base 310, side arms 320, and hooks 330 of the fastening member 300, the fastening member 300 can be more easily fastened into the fastening groove 111.

[0069] In this embodiment and some embodiments, in the circumferential direction DF of the rotation of the second fan blade 230, the fastening member 300 may at least partially overlap with the second engaging member 220, such as... Figure 4 As shown. Based on this, the fastening member 300 can be used to prevent the second engaging member 220 from disengaging from the first engaging member 120 in the opposite direction of the circumferential direction DF.

[0070] In this embodiment and some embodiments, the fan module 10 may further include two stop members 400 disposed on opposite sides of the first housing 110.

The fourth engaging members 240 are detachably disposed within the second engaging grooves 141 of the third engaging members 140. The first engaging members 120 and the third engaging members 140 are staggered on the first housing 110, and the second engaging members 220 and the fourth engaging members 240 are staggered on the second housing 210. Through the configuration of the first engaging members 120 to the fourth engaging members 240, the engagement of the second fan 200 with the first fan 100 can be strengthened. Furthermore, the design of the stop 400 prevents excessive movement when disengaging the fourth locking member 240 from the third locking member 140.

[0071] In this embodiment and some embodiments, each turning segment 122 may have a first positioning surface S1 facing the first fan blade 130. Each second engaging member 220 may have a second positioning surface S2 facing away from the first fan blade 130. The first positioning surface S1 and the second positioning surface S2 are attached to each other and form an acute angle θ with respect to the rotation axis 231 of the second fan blade 230, such as... Figure 4 As shown. By configuring the first positioning surface S1 and the second positioning surface S2, the first fan 100 and the second fan 200 can be positioned relative to each other in a direction parallel to the rotation axis 231. Furthermore, by designing an acute angle θ, the second locking member 220 can be easily locked into the first locking member 120.

[0072] In this embodiment and some embodiments, each turning segment 122 may have a third positioning surface S3 on the side near the first opening 123a. Each second engaging member 220 may have a fourth positioning surface S4 on the side facing away from the fastening member 300. The third positioning surface S3 and the fourth positioning surface S4 are attached to each other and parallel to the rotation axis 231 of the second fan blade 230. By the configuration of the third positioning surface S3 and the fourth positioning surface S4, the first fan 100 and the second fan 200 can be positioned relative to each other in the circumferential direction DF.

[0073] In this embodiment and some embodiments, the extension 121 and the turning section 122 of each first engaging member 120 may share a fifth positioning surface S5 facing the rotation axis 231 of the second fan blade 230. The second housing 210 may have a sixth positioning surface S6 on its outer side. The fifth positioning surface S5 and the sixth positioning surface S6 are attached to each other and parallel to the circumferential direction DF of the rotation of the second fan blade 230. By the configuration of the fifth positioning surface S5 and the sixth positioning surface S6, the first fan 100 and the second fan 200 can be positioned relative to each other in a direction perpendicular to the rotation axis 231.

[0074] In this embodiment and some embodiments, the first housing 110 has a seventh positioning surface S7 on the side facing the second housing 210. The second housing 210 has an eighth positioning surface S8 on the side facing the first housing 110. The seventh positioning surface S7 and the eighth positioning surface S8 are attached to each other and perpendicular to the rotation axis 231 of the second fan blade 230. By configuring the fifth positioning surface S5 and the sixth positioning surface S6, the first fan 100 and the second fan 200 can be further positioned relative to each other in a direction parallel to the rotation axis 231.

[0075] According to the fan module of the above embodiment, the design of the first snap-fit ​​component, the second snap-fit ​​component, and the fastening component allows the first fan and the second fan to be easily assembled together, so that the rotation axis of the first fan blade and the rotation axis of the second fan blade are aligned after assembly, so that the fan module can provide a strong airflow.

[0076] Furthermore, the guide ramp design allows the fastener to be guided by the ramp and thus more smoothly positioned in the fastening groove.

[0077] Furthermore, the fastening member can at least partially overlap with the second locking member in the circumferential direction of the rotation of the second blade, so as to use the fastening member to prevent the second locking member from disengaging from the first locking member.

[0078] Furthermore, the engagement of the second fan with the first fan can be strengthened by the configuration of the first to fourth locking components.

[0079] Furthermore, the design of the stop prevents excessive movement when disengaging the fourth locking piece from the third locking piece.

[0080] Furthermore, the design of forming an acute angle between the first positioning surface and the second positioning surface relative to the rotation axis of the second fan blade facilitates the engagement of the second locking component with the first locking component.

[0081] Furthermore, by configuring the first positioning surface to the eighth positioning surface, the first fan and the second fan can be positioned relative to each other in multiple directions.

[0082] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the scope of protection of the appended claims.
