This creation is about a wind deflector, especially a wind deflector assembly and electronic device.

With the advancement of electronic and communication technology and the popularization of cloud services, the amount of data that the server needs to process is increasing. In order to increase storage space, some servers adopt a dual-layer hard disk structure to support a larger number of hard disks in a limited space. At the same time, in terms of heat dissipation, the fan module in the server generally adopts the structure corresponding to the aforementioned hard disk configuration, and is also matched with the air baffle to achieve the required heat dissipation airflow distribution in the server.

In actual situations, the server may need to replace, pick and place the fan, or adjust the fan structure due to different applications or regular maintenance operations. However, the current air ducts used in the industry have problems that are difficult to assemble and not easy to disassemble, so The existence of the air baffle has long affected the replacement or maintenance of fans and other operations.

In view of this, the present invention provides a wind deflector assembly and an electronic device, the baffle of which can be easily disassembled by switching positions, so as to effectively solve the aforementioned problems of the traditional wind deflector.

The wind deflector assembly includes an assembly plate and a baffle. The assembly board is fixed to the chassis. The fan module is detachably connected to the assembly board. The assembly board has a first hole and a second hole. The baffle plate is rotatably arranged on the assembly board between a first position and a second position. The baffle includes a body part and an elastic arm part. The elastic arm includes a fixed end, a free end, a first positioning protrusion and a second positioning protrusion. The elastic arm part is connected to the main body part via the fixed end. The first positioning protrusion is arranged at the free end. The second positioning protrusion is arranged between the fixed end and the free end. When the baffle is at the first position, the baffle shields the fan module, and the first positioning protrusion and the second positioning protrusion are respectively located in the first and second clamping holes. When the baffle rotates to the second position relative to the assembly board with the first positioning protrusion as the center of rotation, the baffle reveals the fan module, and the second positioning protrusion comes out of the second hole to drive the elastic arm portion to deform. The first positioning protrusion is separated from the first locking hole to release the engagement relationship between the baffle plate and the assembly board.

According to another embodiment of the present invention, a wind deflector assembly is disclosed, which is arranged in a chassis and includes an assembly board and a baffle. The assembly board is detachably fixed to the chassis. The assembly board has a first hole and a second hole. The baffle plate is rotatably arranged on the assembly board between a first position and a second position. The baffle includes a body part and an elastic arm part. The elastic arm includes a fixed end, a free end, a first positioning protrusion and a second positioning protrusion. The elastic arm part is connected to the main body part via the fixed end. The first positioning protrusion is arranged at the free end. The second positioning protrusion is between the fixed end and the free end. When the baffle is at the first position, the first positioning protrusion and the second positioning protrusion are respectively located in the first engaging hole and the second engaging hole. When the baffle plate rotates to the second position relative to the assembly board with the first positioning protrusion as the center of rotation, the second positioning protrusion escapes from the second locking hole to drive the elastic arm portion to deform, so that the first positioning protrusion separates from the first positioning protrusion. The hole is locked to release the engagement relationship between the baffle plate and the assembly board.

The above description of the disclosure of this creation and the description of the following implementation manners are used to demonstrate and explain the spirit and principle of this creation, and to provide a further explanation of the scope of patent application for this creation.

Please refer to Figures 1A~1D. Figure 1A shows a three-dimensional schematic diagram of an electronic device according to an embodiment of this creation, Figure 1B shows a schematic top view of an electronic device according to an embodiment of this creation, and Figure 1C shows one of this creation An exploded schematic diagram of the electronic device of the embodiment. FIG. 1D is a schematic side view of the electronic device of an embodiment of the present invention.

An embodiment of this creation proposes an electronic device 9, which can be, but is not limited to, a server host, but this creation is not limited to the type of the electronic device 9 or the model of the picture. Further, the electronic device 9 may include a chassis 91, and the chassis 91 may be used to house and carry one or more hard disk modules 5, one or more expansion unit modules 6, a carrier 7, and a fan module. 8 and a wind deflector assembly 1. But what needs to be explained here is that the number and configuration of hard disk module 5, expansion unit module 6, carrier frame 7 and fan module 8 are only used to illustrate the function and purpose of the air baffle assembly 1. , Rather than restricting this creation in any way.

In this embodiment, the chassis 91 can accommodate two hard disk modules 5, and the hard disk modules 5 are stacked on one side of the chassis 91 to form a double-layered hard disk structure. In order to make the drawing simple, here or Subsequent drawings omit the hard disks in the hard disk module 5 to show them. The carrier 7 can be disposed on the side of the chassis 91 relatively far away from the hard disk module 5, and can be suspended on the main board (not labeled) of the chassis 91 by any suitable method. The carrier 7 can be used to carry the expansion unit module 6 so that the expansion unit module 6 is located in the upper area of the chassis 91. The upper region here refers to the space in the chassis 91 farther away from its motherboard. Therefore, it is understandable that the region in the chassis 91 located on the same layer below the carrier 7 can be called the lower region, which refers to the lower region in the chassis 91. The space close to its motherboard.

The expansion unit module 6 can, but is not limited to, a combination of a graphics processor (not shown) and a frame (not labeled) accommodating it, and one end of the frame can be equipped with a dedicated cooling fan (not labeled) ).

The air baffle assembly 1 can be movably installed on the chassis 91 and arranged on the side of the hard disk module 5 facing the expansion unit module 6. The fan module 8 is removably installed in the chassis 91 by the assembly board 20 of the air deflector assembly 1, and is adjacent to the hard disk module 5 located in the lower area. In order to make the drawing concise, the fan in the fan module 8 is omitted here or in subsequent drawings.

In this configuration, the air flow F as shown in Fig. 1D is the air flow driven by the fan module 8, which can be guided and restricted by the air guide assembly 1 to concentrate on the hard disk molds in the lower area. Group 5. At the same time, because the air baffle assembly 1 is blocked between the hard disk module 5 and the fan module 8 in the upper area, it helps to concentrate the airflow generated by the cooling fan of the expansion unit module 6 on The hard disk module 5 in the upper area. In other words, the air baffle assembly 1 enables the cooling fan of the expansion unit module 6 and the fan module 8 to effectively dissipate the heat of the hard disk module 5 in the upper and lower areas, and prevents the airflow in different areas from causing heat. Regurgitation occurs. Therefore, with the arrangement of the air baffle assembly 1, the electronic device 9 can only be equipped with a fan module 8 next to one of the hard disk modules 5 for heat dissipation, and the other hard disk module 5 can also use the air guide The guide of the cover assembly 1 effectively utilizes the heat dissipation airflow generated in other areas for heat dissipation. In addition, the wind deflector assembly 1 is a tool-less detachable design, and can switch states to help simplify the process of disassembling and assembling the fan module 8. The detailed description is as follows.

Please refer to Figures 2 to 6 for a detailed description of the wind hood assembly 1. Figure 2 shows an exploded schematic diagram of the wind hood assembly according to an embodiment of this creation, and Figure 3 shows the guide of an embodiment of this creation. A schematic plan view of the assembly plate of the wind hood assembly. Figure 4 is a partial enlarged schematic diagram showing the baffle of the wind hood assembly of an embodiment of the invention. FIG. 5 shows the wind hood assembly of an embodiment of the invention. Fig. 6 is a partially cut-away enlarged schematic diagram showing the wind hood assembly according to an embodiment of the present invention.

In this embodiment, the wind deflector assembly 1 includes a baffle 10 and two assembly plates 20. The assembly board 20 can be respectively fixed on two opposite inner side walls (not labeled) of the chassis 91 by any suitable means, and is adjacent to the side of the hard disk module 5 facing the expansion unit module 6. The baffle 10 is a part of the air guiding hood assembly 1 that is mainly used to guide airflow. The opposite ends of the baffle 10 are respectively detachably disposed on the assembly board 20 so as to be detachably assembled to the chassis 91 via the assembly board 20. The opposite ends of the fan module 8 are respectively detachably disposed on the assembly board 20 to be assembled to the chassis 91 via the assembly board 20. With the assembly board 20, the fan module 8 can be arranged in the hard disk module 5 corresponding to the lower area. , And located below the baffle 10 of the wind deflector assembly 1. The two assembling boards 20 have correspondingly similar structures, so only one of the assembling boards 20 is described below.

In this embodiment, the assembly board 20 can be, but is not limited to, an integrally formed structure of any suitable material, which includes an abutting surface 21, a first hole 22, a second hole 23, and a baffle guide. The guide groove 24, a stop structure 25 and one or more fan guide grooves 26. The abutting surface 21 is the surface of the assembly board 20 facing the other assembly board 20 and used to contact the baffle 10. The first hole 22 is formed on the contact surface 21. The first hole 22 may be, but is not limited to, a circular blind hole or a perforation. The second card hole 23 is formed on the contact surface 21. The second locking hole 23 may be an arc-shaped hole whose center falls on the first locking hole 22. In this embodiment, the angle range from the opposite ends of the second engaging hole 23 to the first engaging hole 22 may be about 45 degrees, but it can also be adjusted according to actual needs.

The baffle guide groove 24 is formed on the contact surface 21. The baffle guide groove 24 is a straight groove extending from the end edge of the self-assembly board 20 relatively far from the bottom plate of the chassis 91 toward the first card hole 22, and is suitable for inserting and sliding one side of the baffle 10. The stop structure 25 protrudes from the contact surface 21 and is adjacent to a side of the baffle guide groove 24 relatively close to the hard disk module 5. The fan guide slot 26 is a straight slot with one end open facing upwards and extending to the bottom plate of the chassis 91, and is suitable for inserting and inserting corresponding protruding structures on opposite sides of the fan module 8 (as shown in FIG. 1C, but not labeled). Sliding, so as to guide the fan module 8 into a predetermined position in the chassis 91. In terms of configuration, the fan guide groove 26 is arranged in one half of the abutting surface 21 of the assembly board 20 (the lower half, or the part corresponding to the lower region), and the first card hole 22, the second card hole 23 and the stopper The board guide groove 24 is disposed on the other half of the abutting surface 21 of the assembly board 20 (such as the upper half, or the portion corresponding to the upper region). It can be seen that by the design of the assembly board 20, the baffle 10 and the fan module 8 can be respectively arranged in the upper and lower regions of the chassis 91.

In this embodiment, the baffle 10 can be, but is not limited to, an integrally formed structure of any suitable material. It includes a body portion 11 and an elastic arm portion 12. The body portion 11 is a plate-shaped and mainly formed on the baffle 10 The part used to guide the airflow. The elastic arm portions 12 are respectively disposed on opposite sides of the main body portion 11, and are a part of the baffle 10 that is used to be detachably disposed on the assembly board 20. The elastic arm portion 12 includes a fixed end 121, a free end 122, a first positioning protrusion 123 and a second positioning protrusion 124. The elastic arm portion 12 is connected to the body portion 11 via the fixed end 121. The free end 122 is a distal end of the elastic arm portion 12 relatively far away from the fixed end 121. Thereby, when the elastic arm portion 12 receives a force, the free end 122 can swing relative to the fixed end 121.

The first positioning protrusion 123 is protruding from the free end 122, and is suitable for being slidably inserted into the baffle guide groove 24 of the assembly board 20, and is suitable for when the baffle 10 further slides to the first hole 22 The first card hole 22 is rotatably inserted. The second positioning protrusion 124 is projected between the fixed end 121 and the free end 122, and is suitable for being slidably inserted into the baffle guide groove 24 of the assembly board 20, and is suitable for rotating with the baffle 10 relative to the assembly board 20 When it reaches a certain angle, it can be slidably inserted into the second card hole 23.

The baffle 10 further includes an elastic positioning protrusion 125, which is adjacent to the fixed end 121 of the elastic arm portion 12. Specifically, the elastic positioning protrusion 125 is located on a side of the fixed end 121 relatively far from the free end 122 . The elastic positioning protrusion 125 can protrude from the surface of the main body 11 when it is not under force, and can sink into the surface of the main body 11 when pressed by an external force.

With the elastic arm portion 12, in addition to the baffle 10 can be detachably installed on the assembly board 20, the baffle 10 can be rotated relative to the assembly board 20 to a side that can be shielded from the fan module 8 to guide the fan module. A first position of the heat dissipation airflow of the group 8 (as shown in the lying state shown in FIG. 1A, FIG. 1D or FIG. 7F) and a first position that can avoid and expose the fan module 8 to allow the fan module 8 to be taken and placed. The second position (as shown in the vertical state shown in FIG. 7C) is described in detail in the subsequent paragraphs.

In addition, in order to maintain the current position of the baffle 10 when rotated to a specific angle with respect to the assembly plate 20, in this embodiment, the wind deflector assembly 1 further includes at least one fixing structure 30, which can be, but is not limited to, It is detachably arranged at opposite ends of the baffle 10. From a further point of view, the fixing structure 30 can be, but is not limited to, a structure integrally formed of any suitable material, which includes an insertion portion 31 and an operation portion 32. The insertion portion 31 is adapted to be detachably inserted into the body portion 11 of the baffle 10 The operating portion 32 is connected to one side of the insertion portion 31 and forms an angle θ with the insertion portion 31. The angle θ is slightly greater than 90 degrees. Therefore, after the insertion portion 31 is inserted into the body portion 11 of the baffle 10, the operating portion 32 faces The direction away from the main body 11 of the baffle 10 is inclined. As shown in the figure, due to the included angle between the insertion portion 31 and the operating portion 32, the operating portion 32 is tilted upward toward one end of the other fixing structure 30 in an unstressed state.

Looking further, the insertion portion 31 has at least one hook 311 for hooking on the body portion 11 of the baffle 10. In addition, the insertion portion 31 also has at least one protrusion 312 protruding from the surface of the insertion portion 31 facing the other fixing structure 30, which helps to abut the body portion 11 when the insertion portion 31 is inserted into the body portion 11 of the baffle 10 Increasing the stability of the insertion portion 31 also helps to reduce the frictional force between the insertion portion 31 and the body portion 11 during the process of inserting the insertion portion 31 into the body portion 11.

In addition, in this embodiment, the wind deflector assembly 1 may further include an elastic extension member 40, which can be fixed to one side of the main body 11 of the baffle 10 in any suitable manner and extends outward from the main body 11 To protrude, the elastic extension member 40 can be composed of a plurality of rubber strips, which can make up the gap between the body portion 11 of the baffle 10 and the fan module 8 and at the same time allow cables to pass through. However, the elastic extension member 40 may be optional, and this creation is not limited to this.

Here, please further refer to FIGS. 7A to 7G, and the assembly and operation instructions of the wind deflector assembly 1 will be used to more clearly clarify the connection relationship and functions between the aforementioned components.

First, as shown in FIG. 7A, the user can first put the opposite ends of the fan module 8 into the chassis 91 along the guide of the fan guide slot 26 of the assembly board 20, so that the fan module 8 corresponds to the hard disk in the lower area Module 5. Then, as shown in FIG. 7B, the user can then put the baffle 10 of the wind deflector assembly 1 into the chassis 91. In detail, the opposite sides of the baffle 10 can pass through the first positioning protrusions on the elastic arm portion 12 123 and the second positioning protrusion 124 are inserted into the baffle guide groove 24 of the assembly board 20, so as to be inserted into the chassis 91 along a straight line through the guide of the baffle guide groove 24. It should be noted that the installation sequence of the fan module 8 and the baffle 10 of the air duct assembly 1 can be reversed according to requirements, rather than being limited to the sequence of drawings.

Then, as shown in FIGS. 7C to 7D, as the baffle 10 is further inserted into the direction of the first hole 22 of the assembly board 20, the first positioning protrusion 123 and the second positioning protrusion 124 on the elastic arm portion 12 follow Slide out the baffle guide groove 24 in sequence, the first positioning protrusion 123 can slide to the position corresponding to the first hole 22 of the assembly board 20, and the second positioning protrusion 124 slides to the first hole of the assembly board 20 22 and the abutment surface 21 between the baffle guide groove 24, but because the second positioning protrusion 124 abuts against the abutment surface 21, the elastic arm portion 12 is deformed, thereby maintaining the first positioning protrusion 123 opposite A state of being far away from the abutting surface 21 without being inserted into the first card hole 22. At this time, it is defined that the baffle 10 is at the second position that is vertical and does not cover the fan module 8. It is understandable that the fan module 8 has to be taken out directly from the chassis 91 at this time.

On the other hand, the elastic positioning protrusion 125 adjacent to the fixed end 121 of the elastic arm portion 12 is suspended beside the first locking hole 22 at the first positioning protrusion 123, and the second positioning protrusion 124 abuts against the abutment. When the junction surface 21 is still located in the baffle guide groove 24 of the assembly board 20 and is stopped by the stop structure 25 of the assembly board 20, the baffle 10 can be stopped or maintained in the second position. In this case, even if the user releases the baffle 10, the baffle 10 can be maintained at the second position without unintended movement.

Then, as shown in FIGS. 7E-7G, the user can slightly force the baffle 10 to rotate relative to the assembly board 20 (in the direction shown by the arrow), so that the aforementioned elastic positioning protrusion 125 is submerged into the surface of the main body 11 of the baffle 10. The stop structure 25 of the assembly board 20 is no longer abutted, and the baffle 10 can rotate with the first positioning protrusion 123 as the center of rotation relative to the assembly board 20 toward the lying state. During the process, the second positioning protrusion 124 detaches from the abutment surface 21 and enters one end of the second engaging hole 23 and can slide along the second engaging hole 23 to the other end of the second engaging hole 23, due to the second positioning protrusion 124 no longer abuts against the abutting surface 21, so the elastic arm portion 12 is elastically reset, so that the first positioning protrusion 123 is inserted into the first locking hole 22. When the second positioning protrusion 124 of the baffle 10 slides to the other end of the second hole 23, the baffle 10 is in a lying state and is shielded above the fan module 8. At this time, the definition baffle 10 is in the first position that lies flat and shields the fan module 8, whereby the baffle 10 can make the airflow generated by the fan module 8 act on the hard disk module corresponding to the fan module 8 Group 5. At the same time, as mentioned above, the baffle 10 is now blocking between the hard disk module 5 and the fan module 8 in the upper area, thus helping to make the airflow generated by the cooling fan of the expansion unit module 6 Focus on the hard disk module 5 in the upper area.

On the other hand, when the baffle 10 is switched from the second position (vertical state) to the first position (flat state), the fixing structure 30 of the wind deflector assembly 1 slides over the fixing on the inner side wall of the chassis 91 The convex hull 911 causes the operating portion 32 of the fixed structure 30 to be squeezed by the inner side wall of the chassis 91, thereby deforming relative to the insertion portion 31 to reduce the angle between the two, and when the baffle 10 reaches the first position, The operating portion 32 is restricted by the fixed convex hull 911 and maintained in the current deformed state. The squeezing of the fixed structure 30 by the chassis 91 at this time can increase the assembly stability of the baffle 10, and also make the baffle 10 more closely fit the chassis 91, thereby eliminating the possibility of interference between the chassis 91 and the baffle 10 due to manufacturing tolerances. The impact caused by the gap. In addition, the restriction of the fixing structure 30 by the fixing convex hull 911 can ensure that the baffle 10 is in the first position and presses the fan module 8, thereby ensuring that the fan module 8 can be maintained at a predetermined position. Based on this, it can be seen that with the design of the wind deflector assembly 1, the installation of the fan module 8 can be completed through simple steps.

Understandably, when the fan module 8 is to be replaced or repaired, it is only necessary to operate the air guide assembly 1 according to the aforementioned steps in reverse. Specifically, the user can first use the elasticity of the fixing structure 30 to pull the operating portion 32 of the fixing structure 30 to disengage it from the fixing protrusion 911 of the chassis 91, and then make the baffle 10 protrude in the first positioning position. The block 123 is the rotation center relative to the assembly board 20 from the first position to the second position (that is, the baffle 10 is turned from the lying state to the vertical state), so that the baffle 10 exposes the fan module 8 without blocking the fan module 8 At that time, the user can pick and place the fan module 8 at that time. In addition, when the baffle plate 10 rotates to the second position, the second positioning protrusion 124 escapes from the second hole 23 and abuts against the contact surface 21, thereby driving the elastic arm portion 12 to deform to make the first positioning The protrusion 123 is separated from the first hole 22 (ie, the state as shown in FIG. 7C). At that time, the engagement relationship between the baffle 10 and the assembly board 20 has been released, and the baffle 10 can be directly drawn away from the assembly board 20.

It can be seen that the baffle 10 of the air duct assembly 1 can not only concentrate the heat dissipation airflow of the fan module 8 on one of the corresponding hard disk modules 5 when in the first position, but also has a fixed fan module that resists pressure. The function of the group 8, and by simply rotating the baffle 10 of the wind deflector assembly 1, the access path of the fan module 8 can be avoided and the fan module 8 can be disassembled and assembled. Therefore, with the wind deflector assembly 1, it is possible to guide the heat dissipation airflow of the fan module 8 while supporting the fan module 8 to be quickly disassembled in a toolless and simple manner, thereby effectively solving the traditional wind deflector. The problem that affects the removal and maintenance of the fan due to the difficulty of disassembly and assembly.

Although the fixing structure of the wind deflector assembly of the foregoing embodiment is a detachable design, this creation is not limited to this. For example, please refer to FIG. 8. FIG. 8 shows a partial enlarged schematic view of the wind deflector assembly of another embodiment of the present creation. In this embodiment, the fixing structure 30' of the wind deflector assembly 1'can also be connected to the block The body portion 11 ′ of the board 10 ′ is an integrally formed structure, and the fixing structure 30 ′ can also be correspondingly engaged with the fixing protrusion 911 of the chassis 91 when the baffle 10 ′ is rotated to the first position.

Of course, those with ordinary knowledge in the art can make various adaptive adjustments based on actual needs without departing from the spirit and scope of this creation, such as changing the number of assembly boards, adjusting assembly The size and position of the holes or grooves on the board, the shape and position of the positioning protrusions of the baffle are adjusted, or part of the structure is omitted. For example, part of the positioning protrusions or the fixing structure can also be omitted.

In summary, according to the air guide assembly and the electronic device disclosed in this creative embodiment, when the baffle is in the first position, it can be engaged with the first and second positioning protrusions and the first and second engaging holes In the assembling board, the baffle can also release the engagement relationship with the assembling board by rotating the first and second positioning protrusions away from the first and second locking holes by rotating relative to the assembling board. Therefore, The baffle allows the wind deflector assembly to support rapid disassembly while taking into account the airflow guidance, so as to effectively solve the problem of traditional wind deflectors that are difficult to disassemble and affect the handling and maintenance of fans.

Although this creation is disclosed above with the aforementioned embodiments, it is not intended to limit this creation. Without departing from the spirit and scope of this creation, all changes and modifications made are within the scope of patent protection of this creation. For the scope of protection defined by this creation, please refer to the attached scope of patent application.
