Description

Fan quick-release structure, fan fixing assembly and fan assembly

Technical Field

The present invention relates to a fan fixed in a computer case, and more particularly, to a fan quick release structure, a fan fixing assembly and a fan assembly.

Background

The computer host needs to be equipped with a forced air cooling mechanism to ensure that the heat generated by the CPU, graphics chip, memory or other high heat components during the operation can be effectively removed, thereby maintaining the normal operation of the system.

A general fan fixing mechanism mainly fixes a fan to a casing structure by fixing members such as screws. The screw is fixed on the casing structure after passing through the fixing hole of the fan, thereby providing good fixing effect. However, in a computer host with a small internal space, for example, a server host with a height of 1U, the tool operation is not easy due to the small space. Therefore, the fan is fixed in the small-height casing mainly by using a tight coupling structure such as a rubber soft plug. Tight combination structures such as rubber soft plugs are prone to inaccurate fixation, and meanwhile, plugging and fixation of a fan power line in a narrow space are not easy to implement. Therefore, the current work of fixing the fan in the small-height casing still has the problem of time consuming assembly.

Detailed Description

Referring to fig. 1, fig. 2 and fig. 3, a fan quick release structure according to an embodiment of the present invention is configured to be mounted on a fan 200, so that the fan quick release structure and the fan 200 are combined into a fan assembly 1. As shown in fig. 1, the fan 200 has two side surfaces 210, and a top surface 220, a bottom surface 230, and two end surfaces connecting the two side surfaces 210. The fan 200 has an air flow passage penetrating both end surfaces of the fan 200 in an air flow direction. The two side surfaces 210, the top surface 220, and the bottom surface 230 are arranged substantially parallel to the direction of airflow.

As shown in fig. 1, fig. 2 and fig. 3, the fan quick release structure includes a first side cover 110, a second side cover 120, a locking member 130, a handle 140 and a supporting member 150.

As shown in fig. 4 and 5, the first side cover 110 and the second side cover 120 are respectively coupled to the two side surfaces 210. The first side cover 110 and the second side cover 120 have an

outer surface

110a,120a and an

inner surface

110b,120b, respectively, and the

inner surfaces

110b,120b face the corresponding side surfaces 210. The first side cover 110 of one of the two side covers 110,120 has a slot 112 communicating the inner surface 110b and the outer surface 110a of the first side cover 110.

As shown in fig. 1, 2 and 3, the fan 200 has a plurality of recesses 250 between the side surface 210, the top surface 220 or the bottom surface 230, between the side surface 210 and the top surface 220, or between the side surface 210 and the bottom surface 230. The fan 200 further has a plurality of fixing holes 260 located in the recess 250, and the extending direction of the fixing holes 260 is parallel to the airflow direction. The first side cover 110 and the second side cover 120 further have a plurality of fixing pins 114,124 disposed corresponding to the

inner surfaces

110b,120b, and the fixing pins 114,124 extend in a direction parallel to the

inner surfaces

110b,120 b. The fixing pins 114 and 124 are inserted into the fixing holes 260 to fix the first side cover 110 and the second side cover 120 to the two side surfaces 210 of the fan 200, respectively.

Referring to fig. 1 to 5, the locking element 130 extends along the edge of the slot 112, and the locking element 130 has a locking block portion 132 and an action portion 134. The latch portion 132 is normally protruded from the outer surface 110a, and the actuating portion 134 is connected to the latch portion 132.

As shown in fig. 4 and 5, an operation space is formed between the operation portion 134 and the inner surface 110b of the first side cover 110. Meanwhile, the actuating portion 134 has a notch 134a facing the inner surface 110b of the first side cover 110.

As shown in fig. 1, fig. 2 and fig. 3, the handle 140 has a first pivot end 141 and a second pivot end 142. The first pivot end 141 is pivoted to the first side cover 110, and the second pivot end 142 is pivoted to the second side cover 120, so that the handle 140 can rotate relative to the first side cover 110 and the second side cover 120 to move between a first position P1 and a second position P2.

As shown in fig. 3 and 5, in the first position P1, the handle 140 is close to the top surface 220. In the second position P2, the handle 140 and the top surface 220 form an angle therebetween, which may be set to approximately 90 degrees, so that the user can directly grip the handle 140 to move the fan assembly 1.

As shown in fig. 1, 4 and 5, the first pivot end 141 is pivoted between the first side cover 110 and the actuating portion 134. The first side cover 110 has a pivot hole 110c, the first pivot end 141 has a pivot 141a, and the pivot 141a is inserted into the pivot hole 110c of the first side cover 110.

As shown in fig. 1, a lug 122 extends from the inner surface 120b of the second side cover 120, and the lug 122 is spaced apart from the second side cover 120. The second pivot end 142 is pivotally connected between the second side cover 120 and the lug 122. The second side cover 120 has a pivot hole 120c, the second pivot end 142 has a pivot 142a, and the pivot 142a is inserted into the pivot hole 120c of the second side cover 120.

As shown in fig. 1, 4 and 5, the propping element 150 is disposed at the first pivot end 141 and corresponds to the action portion 134 of the locking element 130. The propping member 150 is integrally formed on the handle 140, but it is not excluded that the propping member 150 is a separate component and is coupled to the first pivoting end 141.

The first and second side covers 110,120 are only used to separate the side covers 110,120, but not to limit the positions of the slot 112 and the locking element 130. The slot 112 and the locking element 130 may be disposed on the second side cover 120, or the slot 112 and the locking element 130 may be disposed on both the first side cover 110 and the second side cover 120. Similarly, "the first and second" of the first pivot end 141 and the second pivot end 142 are also used to clearly illustrate the relative position relationship between the propping element 150 and the locking element 130. The propping element 150 may be disposed on the second pivot end 142 instead of the slot 112 and the locking element 130 of the second side cover 120, or the propping element 150 may be disposed on both the first pivot end 141 and the second pivot end 142 to correspond to the different slot 112 and the locking element 130.

Referring to fig. 3, 5 and 6, when the handle 140 is located at the first position P1, the abutting element 150 enters the notch 134a, such that the actuating portion 134 approaches toward the first side cover 110 and can be tightly attached to the first pivot end 141, and the latch portion 132 protrudes from the outer surface 110a of the first side cover 110. When the handle 140 is located at the second position P2, the abutting member 150 is disengaged from the notch 134a, and pushes the actuating portion 134 in a disengaging direction away from the inner surface 110b, thereby driving the latch portion 132 to move from the outer surface 110a of the first side cover 110 toward the inner surface 110b, and not to protrude from the outer surface 110a of the first side cover 110.

As shown in fig. 5 and 6, the shape of the abutting member 150 substantially matches the recess 134 a. When the handle 140 is at the first position P1, the abutting member 150 can be completely received in the notch 134a without interfering with the acting portion 134. At this time, the first pivoting end 141 is substantially in contact with the actuating portion 134, and the actuating portion 134 approaches the first side cover 110 and is tightly attached to the first pivoting end 141, so that the latch portion 132 may protrude from the outer surface 110a of the first side cover 110 as much as possible. As shown in fig. 4 and 7, when the handle 140 is at the second position P2, the stroke of the pushing member 150 pushing the action portion 134 must be enough to allow the latch portion 132 to have a sufficient moving stroke, so that the latch portion 132 does not protrude from the outer surface 110a of the first side cover 110.

As shown in fig. 6 and 7, in order to achieve the above requirement, a certain proportional relationship between the latch portion 132 and the abutting member 150 needs to be satisfied. When the handle 140 is at the first position P1, the height of the latch portion 132 protruding from the outer surface 110a of the first side cover 110 is defined as a first height H1, and after the handle 140 moves from the first position P1 to the second position P2, the stroke of the pushing portion 134 of the abutting member 150 is defined as a second height H2. The second height H2 is preferably greater than or equal to the first height H1. More specifically, in the above embodiment, the second height H2 is the height of the portion of the abutting element 150 accommodated in the notch 134a, and when the abutting element 150 is separated from the notch 134a and contacts the actuating portion 134, the actuating portion 134 can be pushed to move by the stroke of the second height H2, so as to drive the latch portion 132 to move by the second height H2.

As shown in fig. 1, fig. 2 and fig. 3, in an embodiment, the fan quick release structure further includes a bracket 160 extending from one of the two side covers 110,120 (not limited to the first side cover 110 or the second side cover 120), and the position of the bracket 160 corresponds to one of the two end surfaces of the fan 200, and substantially protrudes from the end surface. The bracket 160 is used to fix the fan joint 300, so that the power cord of the fan 200 and the fan joint 300 become a part of the fan assembly 1, which is beneficial to the assembly and disassembly of the fan assembly 1.

Referring to fig. 8 and 9, a fan fixing assembly for fixing a fan 200 at a specific position, such as a specific position in a computer casing, according to another embodiment of the present invention is disclosed. The fan fixing assembly has a fan case 400 and one or more fan quick release structures for fixing one or more fans 200 in the fan case 400. The fan case 400 may be a separate component that is fastened to the computer housing by screws, rivets or other fastening mechanisms. The fan case 400 may also be a part of a computer casing, that is, the fan fixing assembly further includes a casing 500, the casing 500 has an inner space, and the fan case 400 is located in the inner space of the casing 500 and fixed to the casing 500.

As shown in fig. 8 and 9, the fan case 400 has at least two sidewalls 410 and an accommodating space 420 between the two sidewalls 410, and one of the two sidewalls 410 has a fastening hole 415 corresponding to the fastening block portion 132 of the fan quick release structure. The number of the accommodating spaces 420 is matched with the number of the fan quick release structures and the fans 200. Each accommodating space 420 is used for accommodating one fan quick release structure and the fan 200 combined with the fan quick release structure.

As shown in fig. 9, 10 and 11, the first side cover 110 and the second side cover 120 of the fan quick release structure are combined with two opposite side surfaces 210 of the fan 200. Meanwhile, the fan quick release structure is disposed in the accommodating space 420, and the locking portion 132 is locked into the locking hole 415, so as to fix the fan 200 to the fan case 400. The adjacent accommodating spaces 420 may also share the side wall 410, that is, the same side wall 410 corresponds to both the first side cover 110 of one fan quick release structure and the second side cover 120 of the other fan quick release structure; in this case, each sidewall 410 needs to be provided with a fastening hole 415.

As shown in fig. 1 and 10, the latch 132 has a guiding inclined surface 132a, and when the handle 140 is located at the second position P2, the latch 132 does not protrude from the outer surface 110a of the first side cover 110. At this time, the user can grip the handle 140 and place the fan 200 together with the fan quick release structure between the two sidewalls 410. The first side cover 110 and the second side cover 120 respectively correspond to the two side walls 410, and particularly, the first side cover 110 provided with the latch 132 needs to correspond to the side wall 410 provided with the latch hole 415. If the handle 140 is not located at the second position P2, the latch 132 slightly protrudes from the outer surface 110a of the first side cover 110. At this time, when the guiding inclined surface 132a contacts the top edge of the sidewall 410, the guiding locking block portion 132 is retracted to contact the surface of the sidewall 410, so as to avoid the situation that the fan quick-release structure cannot be placed into the accommodating space 420 due to the slightly protruding locking block portion 132.

As shown in fig. 11, when the fan quick release structure is completely received in the receiving space 420 between the two side walls 410 and the handle 140 is located at the first position P1, the latch portion 132 is released to protrude from the outer surface 110a of the first side cover 110 and is locked into the locking hole 415, thereby fixing the fan 200 between the two side walls 410.

As shown in fig. 11, the fan 200 is limited between the two sidewalls 410, and the fan 200 is prevented from being separated from the accommodating space 420 by the combination of the locking block 132 and the locking hole 415, so that the fan 200 can be effectively fixed. Meanwhile, the process of fixing the fan 200 only requires to simply place the fan quick release structure and the fan 200 combined with the fan quick release structure, and rotate the handle 140 to the first position P1. The process of fixing the fan 200 does not need to use tools, and the fan quick-release structure is tightly close to the outside of the fan 200 without forming a protruding structure, so that the fan quick-release structure can be used in narrow space.

As shown in fig. 12, at the same time, the bracket 160 and the fan connector 300 also move toward the housing 500, so as to drive the fan connector 300 to be plugged into an electrical connector 510. The electrical connector 510 is disposed in the housing 500 and corresponds to the bracket 160 for connecting the fan connector 300. The electrical connector 510 may be directly disposed on the inner wall of the housing 500, and may be disposed on a circuit board 520, and the circuit board 520 is fixed on the inner wall of the housing 500, so as to indirectly dispose the electrical connector 510 on the inner wall of the housing 500.

As shown in fig. 10, when the fan 200 is to be disassembled, the user pulls the handle 140 upward to make the handle 140 reach the second position P2, and the latch 132 is disengaged from the latch hole 415 to release the first side cover 110. At this time, the user can detach the fan 200 from the fan case 400 by pulling the handle 140 upward continuously.

With the quick-release structure of the fan of the present invention, the fan 200 can be disassembled by simply pulling and placing the handle 140. Meanwhile, the fan 200 is still fixed through the buckle and the limiting structure, and a good fixing effect is achieved. In at least one embodiment, the fan joint 300 is also integrated into the fan quick-release structure, so that the fan joint 300 can be plugged and unplugged simultaneously when the fan 200 is disassembled and assembled, thereby further improving the convenience provided by the present invention.
