Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computing devices, and in particular, to an air guide device and a computing device. BACKGROUND

[0002] Currently, multiple air blocking structures can be arranged in a server, a switch or other computing device to construct an air flow pattern meeting the heat dissipation requirement inside the computing device. However, the mounting structure of the air blocking structure needs to occupy the case space of the computing device. CONTENT OF THE UTILITY MODEL

[0003] The present application provides an air guide device and a computing device, which saves the extra occupation of the case space.

[0004] In a first aspect, the present application provides an air guide device. The air guide device comprises an air blocking structure, a first clamping member and a second clamping member. The first clamping member is arranged on the mounting surface of the air blocking structure, the mounting surface faces the circuit board, and the first clamping member is used to cooperate with the slot on the circuit board. The second clamping member is movably arranged on the side surface of the air blocking structure. The second clamping member has an initial position and a target position. In the initial position, the end of the second clamping member facing the circuit board is separated from the clamping hole of the circuit board, and in the target position, the end is inserted into the clamping hole.

[0005] In the technical solution of the present application, the first clamping member is arranged on the mounting surface of the air blocking structure, and the second clamping member is movably arranged on the side surface of the air blocking structure. When the region of the circuit board where the air guide device needs to be arranged has a slot, the first clamping member can be used to cooperate with the slot on the circuit board of the computing device, so that the air guide device is arranged on the circuit board. When the region of the circuit board of the computing device where the air guide device needs to be arranged does not have a slot, the end of the second clamping member in the target position can be used to cooperate with the clamping hole, so that the air guide device is arranged on the circuit board. Moreover, since the second clamping member has an initial position and a target position, in the initial position, the end of the second clamping member facing the circuit board can be separated from the clamping hole, and in the target position, the end of the second clamping member facing the circuit board can be inserted into the clamping hole. Therefore, the movable feature of the second clamping member can be used to adjust the position of the end of the second clamping member, so as to ensure that the first clamping member cooperates with the slot normally without the influence of the second clamping member, and the second clamping member cooperates with the clamping hole normally without the influence of the first clamping member.

[0006] It can be seen that the air guide device can be matched with the slot and the clamping hole on the circuit board by the first clamping piece and the second clamping piece, and can adapt to the wind blocking requirements of the two areas with the slot and without the slot on the circuit board. Since the first clamping piece and the second clamping piece are part of the air guide device, the air guide device can be installed on the circuit board without the help of additional mounting pieces, and therefore, the installation of the air guide device can reduce the overall space occupation of the computing device.

[0007] In a possible implementation, when the second clamping piece is in the initial position, the first clamping piece is used to be matched with the slot. The initial position and the target position are distributed along the installation direction of the air guide device, and therefore, the distance between the end of the second clamping piece towards the circuit board and the circuit board is relatively far, so that there is a gap between the end of the second clamping piece towards the circuit board and the circuit board, to prevent interference between the end of the second clamping piece towards the circuit board and the circuit board, so that the first clamping piece can be normally matched with the slot.

[0008] In a possible implementation, when the second clamping piece is in the target position, the first clamping piece is separated from the end of the circuit board towards the circuit board, and the second clamping piece is inserted into the clamping hole towards the end of the circuit board, to prevent interference between the end of the first clamping piece towards the circuit board and the circuit board, so that the second clamping piece can be normally inserted into the clamping hole.

[0009] In a possible implementation, the side surface of the wind blocking structure is provided with a limiting structure. When the end of the second clamping piece towards the circuit board is inserted into the clamping hole, the second clamping piece is matched with the limiting structure in the target position, so that the second clamping piece can be stably kept in the target position, to prevent the second clamping piece from being separated from the clamping hole due to position deviation.

[0010] In a possible implementation, the side surface of the wind blocking structure is further provided with a first limiting part and a second limiting part. The first limiting part and the second limiting part can constitute the limiting structure. Since the initial position and the target position are distributed along the installation direction of the air guide device, and the installation direction of the air guide device can be the direction in which the end of the second clamping piece towards the circuit board is inserted into the clamping hole, when the first limiting part and the second limiting part are distributed along the installation direction of the air guide device, the second clamping piece is matched with the first limiting part in the initial position, and the second clamping piece is matched with the second limiting part in the target position.

[0011] When the second clamping piece is matched with the first limiting part in the initial position, the first limiting part can lock the second clamping piece in the initial position. When the second clamping piece is matched with the first limiting part in the target position, the first limiting part can lock the second clamping piece in the target position.

[0012] In a possible implementation, the surface of the second clamping piece facing away from the side surface has an unlocking portion. The unlocking portion is used to separate the second clamping piece from the first limiting portion in the initial position, and separate the second clamping piece from the second limiting portion in the target position.

[0013] It can be seen that the unlocking function of the unlocking portion can unlock the second clamping piece from the initial position, so that the second clamping piece can be moved from the initial position to the target position, thereby ensuring that the end of the second clamping piece facing the circuit board can be inserted into the clamping hole; the unlocking function of the unlocking portion can unlock the second clamping piece from the target position, so that the second clamping piece can be moved from the target position to the initial position, thereby preventing the second clamping piece from interfering with the cooperation of the first clamping piece and the slot.

[0014] In a possible implementation, the second clamping piece includes an elastic connecting portion and a positioning portion. The elastic connecting portion is movably arranged on the side surface. The positioning portion is arranged at the end of the elastic connecting portion close to the mounting surface. At this time, the positioning portion can be used to cooperate with the clamping hole.

[0015] Since the elastic connecting portion is movably arranged on the side surface, in the initial position, the elastic connecting portion deforms under the force of the unlocking portion, so that the unlocking portion drives the elastic connecting portion to separate from the first limiting portion, thereby achieving the purpose of separating the second clamping piece from the first limiting portion by the unlocking portion, thereby unlocking the second clamping piece from the initial position; in the target position, the elastic connecting portion deforms under the force of the unlocking portion, so that the elastic connecting portion separates from the second limiting portion, thereby achieving the purpose of separating the second clamping piece from the second limiting portion by the unlocking portion, thereby unlocking the second clamping piece from the target position.

[0016] In a possible implementation, the surface of the second clamping piece facing the side surface has a connecting portion. The connecting portion cooperates with the first limiting portion in the initial position and cooperates with the second limiting portion in the target position.

[0017] In a possible implementation, the first limiting portion includes a first limiting hole arranged on the side surface, and the second limiting portion includes a second limiting hole arranged on the side surface. The connecting portion is a locking piece, so that the first limiting hole is used to be buckled with the locking piece in the initial position, and the second limiting hole is used to be buckled with the locking piece in the target position.

[0018] In a possible implementation, the side surface further has a limiting track. The limiting track extends along the mounting direction of the air guide device, and the surface of the second clamping piece facing the side surface has a guide protrusion arranged in the limiting track. Since the limiting track extends along the mounting direction of the air guide device, when the guide protrusion is arranged in the limiting track, the guide protrusion and the limiting track can guide the second clamping piece, thereby ensuring that the second clamping piece can be switched between the initial position and the target position.

[0019] In a possible implementation, the mounting surface has a guide through hole, and the second clamping member is arranged in the guide through hole. When the second clamping member is switched between the initial position and the target position, the guide through hole can guide the second clamping member to prevent the second clamping member from deviating. For example, when the second clamping member is moved from the initial position to the target position, the second clamping member is guided by the guide through hole, so that the end of the second clamping member towards the circuit board can be accurately inserted into the clamping hole.

[0020] In a second aspect, the present application further provides a computing device, including a cabinet, a circuit board arranged in the cabinet, and the air guiding device according to the first aspect or any possible implementation of the first aspect. The circuit board has a clamping hole. The air guiding device includes a second clamping member matched with the clamping hole.

[0021] In a possible implementation, the circuit board further includes a slot. The air guiding device includes a first clamping member matched with the slot.

[0022] The beneficial effects of the second aspect or the possible implementation of the embodiment of the present application can refer to the beneficial effects of the air guiding device of the first aspect or any possible implementation of the first aspect, which will not be repeated here.

[0033] Embodiments of the present application provide a computing device, which can be a server, a switch, and the like, but is not limited thereto. Figure 1 A structural schematic diagram of a computing device according to an embodiment of the present application is shown. For convenience of description, it is defined herein that Figure 1 The length direction of the computing device 100 shown is the x-axis direction, the width direction is the y-axis direction, and the height direction is the z-axis direction. The terms "front", "back", "top", and "bottom" and the like mentioned in the description of the computing device 100 are described according to the orientation of the accompanying drawings, with the x-axis negative direction being "front", the x-axis positive direction being "back", the z-axis positive direction being "top", and the z-axis negative direction being "bottom", which do not form a limitation on the computing device 100 in the actual application scenario. Figure 1 The length direction of the computing device 100 shown is the x-axis direction, the width direction is the y-axis direction, and the height direction is the z-axis direction. The terms "front", "back", "top", and "bottom" and the like mentioned in the description of the computing device 100 are described according to the orientation of the accompanying drawings, with the x-axis negative direction being "front", the x-axis positive direction being "back", the z-axis positive direction being "top", and the z-axis negative direction being "bottom", which do not form a limitation on the computing device 100 in the actual application scenario.

[0034] As shown in the structural schematic diagram of the computing device 100, the computing device 100 includes a processor 110, a memory 120, a storage 130, a communication interface 140, and a bus 150. Figure 1As shown, the computing device 100 can be a server, computer, switch, or other similar device. In this embodiment, the computing device 100 is described using a server as an example. The computing device 100 includes a chassis 101, a circuit board 102, and at least one air guide device snapped onto the circuit board 102. For example, the circuit board 102 can be located at the bottom of the chassis 101. Besides being snapped onto the circuit board 102, the air guide device can also be connected to the rear end of the chassis 101 to ensure the stability of the air guide device. The circuit board 102 has slots (e.g., a first slot K1 and a second slot K2) and snap-fit ​​holes (…). Figure 1 (Not shown), so that the air guide device can be engaged with a snap-fit ​​hole (e.g., snap-fit) or a slot (e.g., snap-fit).

[0035] In one alternative approach, the number of air guiding devices can be one or more. For example, the number of air guiding devices can be two, namely... Figure 1 The first air guide device 104A and the second air guide device 103B are shown. The first air guide device 104A can be engaged with the snap-fit ​​hole, and the second air guide device 103B can be snapped onto the circuit board 102.

[0036] like Figure 1 As shown, the structures of the first air guide device 104A and the second air guide device 103B can be identical. This type of air guide device can either be directly snapped into a slot to guide airflow in the slotted area, allowing air to flow from the front to the rear of the chassis 101 in the slotless area, or it can be snapped into a snap-fit ​​hole to guide airflow in the slotless area, allowing air to flow from the front to the rear of the chassis 101 in the slotless area. Furthermore, when the first air guide device 104A and the second air guide device 103B are installed via snap-fit, they are mounted on the circuit board 102 without the need for additional mounting parts. Therefore, the air guide devices of this embodiment can reduce the overall space occupied by the computing device 100, ensuring the overall configuration of the computing device 100 and reducing consumable and assembly costs.

[0037] For example, when the air guide device has a first snap-fit ​​member and a second snap-fit ​​member, and the circuit board has a snap-fit ​​hole, the second snap-fit ​​member of the air guide device mates with the snap-fit ​​hole (e.g., the second snap-fit ​​member is inserted into the snap-fit ​​hole). As another example, when the circuit board also includes a slot, the first snap-fit ​​member of the air guide device mates with the slot (e.g., the first snap-fit ​​member is inserted into the slot).

[0038] In one alternative approach, such as Figure 1As shown, the computing device 100 also includes a fan system 104, a central processing unit (CPU) 105, a memory module 106, and electronic components 107, all housed within a chassis 101. The fan system 104, memory module 106, electronic components 107, and CPU 105 are all electrically connected to a circuit board 102. For example, the circuit board 102 can be a server motherboard, and the electronic components 107 can include power supply chips, power transistors, power inductors, etc.

[0039] like Figure 1 As shown, the fan system 104, circuit board 102, and electronic components 107 are distributed along the front to rear direction of the chassis 101, with the fan system 104 spaced apart from the circuit board 102, and the circuit board 102 spaced apart from the electronic components 107. The fan system 104 is distributed along the positive x-axis and may include multiple fan units. The multiple fan units can drive air to flow along the positive x-axis in the figure, realizing ventilation and heat dissipation for the circuit board 102, central processing unit 105, memory module 106, and electronic components 107.

[0040] In one example, such as Figure 1 As shown, the circuit board 102 can have multiple slots. In this embodiment, "multiple" refers to two or more. These slots are distributed along the y-axis, forming multiple groups. A central processing unit 105 can be placed between adjacent groups of slots. For example, each group of slots may include a first slot K1 and a second slot K2, distributed along the direction closest to the central processing unit 105. A memory module 106 is inserted into the second slot K2, allowing the memory module 106 to be electrically connected to the circuit board 102 via the first slot K1.

[0041] For example, such as Figure 1 As shown, the first slot K1 is a Peripheral Component Interconnect Express (PCIe) slot, and the second slot K2 can be a Dual-Inline-Memory Module (DIMM). The first slot K1 can be used to connect expansion cards such as graphics cards, sound cards, network cards, solid-state drives, USB 3.0 / 3.1 interface expansion cards, or Redundant Array of Independent Disks (RAID) cards.

[0042] like Figure 1As shown in the figure, when the first slot K1 is not plugged with an expansion card, the first air guide device 104A can be plugged into the first slot K1. For example, when the first air guide device 104A has a first clamping member and a second clamping member, the first air guide device 104A can be inserted into the first slot K1 through the first clamping member, so that the first air guide device 104A is plugged into the first slot K1.

[0043] As shown in the figure, Figure 1 As shown in the figure, when the circuit board 102 is located in the area of the second slot K2 away from the first slot K1, a clamping hole can be opened in the area of the second slot K2 away from the first slot K1, so that the second air guide device 103B can be clamped in the clamping hole. For example, when the second air guide device 103B has a first clamping member and a second clamping member, the second air guide device 104B can be inserted into the clamping hole through the second clamping member, so that the second air guide device 104B is plugged into the clamping hole.

[0044] As shown in the figure, Figure 2 As shown in the figure, under the action of the fan system 104, air can flow through the gap between the first air guide device 104A and the memory stick 106, the gap between the memory stick 106 and the second air guide device 104B, and the gap between the second air guide device 104B and the central processing unit 105, and is delivered to the area where the electronic device 107 is located, so as to ventilate and cool the electronic device 107. It can be seen that in the embodiment of the application, the first air guide device 104A can guide air in the place where there is a slot but no card is inserted, and the second air guide device 104B can guide air in the place where there is no slot, so that the air introduced into the case 101 by the fan system 104 is guided by the first air guide device 104A and the second air guide device 104B to cool the electronic device 107 well, solving the problem of high heat of the electronic device 107.

[0045] The embodiment of the application provides a kind of air guide device, which can be installed in computing device, Figure 3 Fig. 1 shows a perspective structural schematic diagram of the air guide device of the embodiment of the application, Figure 4 Fig. 2 shows a schematic diagram of the cooperation relationship between the first clamping member of the embodiment of the application and the circuit board, Figures 2 to 4 Fig. 3 shows a schematic diagram of the cooperation relationship between the second clamping member of the embodiment of the application and the circuit board. As Figures 2 to 4 The air guide device 200 of the embodiment of the application includes: a wind blocking structure 201, a first clamping member 202 and a second clamping member 203.

[0046] As shown in the figure, Figures 2 to 4As shown, the mounting surface of the wind blocking structure 201 can be opposite to the circuit board 301. When the first clamping member 202 is arranged on the mounting surface of the wind blocking structure 201, the mounting surface can face the circuit board 301, and the first clamping member 202 is used to cooperate with the slot 301A on the circuit board 301. For example, when the air guiding device 200 is applied to a computing device, the first clamping member 202 included in the air guiding device 200 is clamped with the slot 301A on the circuit board 301, so that the air guiding device 200 is arranged on the circuit board 301 by cooperation of the first clamping member 202 and the slot 301A on the circuit board 301 when the area of the circuit board 301 where the air guiding device 200 needs to be arranged has the slot 301A.

[0047] As shown in Figures 2 to 4 , the second clamping member 203 is movably arranged on the side surface of the wind blocking structure 201. The second clamping member 203 has an initial position and a target position, and the initial position and the target position are distributed along the mounting direction of the air guiding device 200. Here, the mounting direction of the air guiding device 200 can refer to the insertion direction of the first clamping member 202 into the slot 301A, so that the end of the second clamping member 203 is separated from the clamping hole 301B in the initial position, and the end of the second clamping member 203 is inserted into the clamping hole 301B in the target position.

[0048] In the embodiment of the present application, as shown in Figure 2 , when the air guiding device 200 is mounted on the circuit board 301, the end of the second clamping member 203 can refer to the end of the second clamping member 203 facing the circuit board 301. When the second clamping member 203 is in the initial position, the distance between the second clamping member 203 and the circuit board 301 is relatively far, so that the end of the second clamping member 203 facing the circuit board 301 is separated from the clamping hole in the initial position; when the second clamping member 203 is in the target position, the distance between the second clamping member 203 and the circuit board 301 is relatively close, so that the end of the second clamping member 203 facing the circuit board 301 can be inserted into the clamping hole 301B in the target position. It can be seen that when the area of the circuit board 301 where the air guiding device 200 needs to be arranged does not have the slot 301A, the end of the second clamping member 203 facing the circuit board 301 can be inserted into the clamping hole 301B on the circuit board 301, so that the air guiding device 200 is arranged on the circuit board 301.

[0049] In an optional manner, as shown in Figure 3 and Figure 1 , the air guiding device 200 of the embodiment of the present application is Figure 1When the first air guide device 104A is in the first air guide device, when the second snap-fit ​​203 is in the initial position, the end of the second snap-fit ​​203 facing the circuit board 301 is separated from the circuit board 301. Therefore, when the first snap-fit ​​202 included in the first air guide device is engaged with the slot 301A on the circuit board 301, the end of the second snap-fit ​​203 facing the circuit board 301 will not interfere with the engagement between the first snap-fit ​​202 and the slot 301A.

[0050] When the area of ​​circuit board 301 where the air guide device 200 needs to be installed has a slot 301A (e.g.) Figure 2 When the first slot K1 is in the circuit, the initial position and the target position are distributed along the installation direction of the air guide device 200, making the distance between the initial position and the circuit board 301 relatively large, while the distance between the target position and the circuit board 301 relatively small. Therefore, the movable feature of the second latching member 203 can be used to adjust the position of the end of the second latching member 203 facing the circuit board 301, so that when the second latching member 203 is in the initial position, the distance between the second latching member 203 and the circuit board 301 is relatively large. In this way, the second latching member 203 can be separated from the latching hole 301B on the circuit board 301 to prevent the end of the second latching member 203 facing the circuit board 301 from interfering with the circuit board 301, so that the first latching member 202 can normally cooperate with the slot 301A on the circuit board 301 without the influence of the second latching member 203.

[0051] In one alternative approach, such as Figure 4 and Figure 1 As shown, when the air guide device 200 of this application embodiment is Figures 2 to 4 When the second air guide device 104B is in place, if the second latching member 203 is in the target position, the end of the first latching member 202 facing the circuit board 301 separates from the slot 301A, and the end of the second latching member 203 facing the circuit board 301 inserts into the latching hole 301B. When the area of ​​the circuit board 301 where the air guide device 200 needs to be installed does not have a slot 301A but has a latching hole 301B, the movable feature of the second latching member 203 can be used to adjust the position of the end of the second latching member 203 facing the circuit board 301 so that the second latching member 203 is in the target position. In this way, the distance between the end of the second latching member 203 facing the circuit board 301 and the circuit board 301 is relatively close, and the end of the second latching member 203 can be inserted into the latching hole 301B on the circuit board 301. When the second connector 203 is in the target position, the distance between the end of the first connector 202 facing the circuit board 301 and the circuit board 301 is relatively far. Therefore, the end of the first connector 202 facing the circuit board 301 is separated from the circuit board 301 to prevent interference between the end of the first connector 202 facing the circuit board 301 and the circuit board 301, thereby ensuring that the second connector 203 can be properly inserted into the connector hole 301B.

[0052] In one alternative approach, such as Figures 2 to 4 As shown, when the distance between the slot 301A and the snap-fit ​​hole 301B of the circuit board 301 is relatively close, while the first snap-fit ​​member 202 snaps into the slot 301A, the second snap-fit ​​member 203 can be located at the target position, and the second snap-fit ​​member 203 is inserted into the snap-fit ​​hole 301B towards the end of the circuit board 301, so as to increase the stability of the air guide device 200 installed on the circuit board 301.

[0053] It can be seen that, as Figure 2 As shown, the air guide device 200 of this embodiment can be configured by first snap-fit ​​202 and second snap-fit ​​203 engaging with slots 301A and snap-fit ​​holes 301B on the circuit board 301 to meet the airflow requirements of both areas on the circuit board 301 with and without slots 301A. Since the first snap-fit ​​202 and second snap-fit ​​203 are part of the air guide device 200, the air guide device 200 can be installed on the circuit board 301 without additional mounting components. Therefore, the installation of the air guide device 200 in this embodiment can reduce the overall space occupied by the computing device, ensure the overall configuration of the computing device, and reduce consumable and assembly costs. Furthermore, the air guide device 200 can be installed on the circuit board 301 without additional mounting components, reducing design limitations of the chassis.

[0054] It should be noted that, as Figure 1 As shown, the air guide device 200 of this embodiment further includes a connector 204 disposed on the windbreak structure 201. When the air guide device 200 is mounted on the circuit board 301, the connector 204 included in the air guide device 200 and Figure 2 The rear end of the chassis 101 is connected to ensure the stability of the air guide device 200 when it is installed on the circuit board 301.

[0055] In one possible implementation, such as Figure 5 As shown, the windbreak structure 201 of this application embodiment has a limiting structure on its side. The second snap-fit ​​member 203 cooperates with the limiting structure in the initial position and the target position, respectively, so as to ensure that the second snap-fit ​​member 203 will not have a large displacement whether it is in the initial position or the target position.

[0056] Figure 2 A schematic diagram of the rear structure of the air guide device according to an embodiment of this application is shown. Figure 5 and Figures 2 to 5As shown, the side of the air guide device 200 in this embodiment of the application is further provided with a first limiting part 2011A and a second limiting part 2011B, which can constitute a limiting structure. Since the initial position and the target position are distributed along the installation direction of the air guide device 200, the first limiting part 2011A and the second limiting part 2011B are distributed along the installation direction close to the air guide device 200, so that in the initial position, the second snap-fit ​​member 203 cooperates with the first limiting part 2011A, and in the target position, the second snap-fit ​​member 203 cooperates with the second limiting part 2011B.

[0057] like Figure 2 As shown, in the initial position, the second card connector 203 engages with the first limiting part 2011A, which locks the second card connector 203 in the initial position, preventing interference with the engagement of the first card connector 202 and the slot 301A due to positional displacement of the second card connector 203. In the target position, the second card connector 203 engages with the second limiting part 2011B, which locks the second card connector 203 in the target position, ensuring that the end of the second card connector 203 near the circuit board 301 is reliably inserted into the card slot 301B.

[0058] In one alternative approach, such as Figure 5 and Figure 2 As shown, the second latching member 203 has a connecting portion 203A on its side-facing surface. This connecting portion 203A engages with the first limiting portion 2011A in the initial position and with the second limiting portion 2011B in the target position. For example, the connecting portion 203A may include a locking element, the first limiting portion 2011A may include a first limiting hole on the side, and the second limiting portion 2011B may include a second limiting hole on the side. In this case, the second latching member 203 engages with the first limiting portion 2011A by engaging with the locking element in the initial position via the first limiting hole, and engages with the second limiting portion 2011B by engaging with the locking element in the target position via the second limiting hole.

[0059] It should be noted that, in the embodiments of this application, as Figure 5 and Figure 2 As shown, the first limiting hole and the second limiting hole can be through holes that pass through the second snap-fit ​​part 203, or they can be blind holes with one end open, as long as the first limiting hole and the second limiting hole can be fastened to the locking part.

[0060] In one alternative approach, such as Figure 5 and Figure 2As shown, the surface of the second clamping piece 203 away from the side surface has an unlocking portion 203B. The unlocking portion 203B separates the second clamping piece 203 from the first limiting portion 2011A in the initial position and separates the second clamping piece 203 from the second limiting portion 2011B in the target position. The unlocking function of the unlocking portion 203B can unlock the second clamping piece 203 from the initial position, so that the second clamping piece 203 can move from the initial position to the target position, thereby ensuring that the end of the second clamping piece 203 towards the circuit board 301 can be inserted into the clamping hole 301B; the unlocking function of the unlocking portion 203B can unlock the second clamping piece 203 from the target position, so that the second clamping piece 203 can move from the target position to the initial position to prevent the second clamping piece 203 from interfering with the cooperation of the first clamping piece 202 and the slot 301A.

[0061] Optionally, as shown in Figure 2 The second clamping piece 203 can include an elastic connecting portion 2031 and a positioning portion 2032. The elastic connecting portion 2031 is movably arranged on the side surface. The positioning portion 2032 can be arranged on the end of the elastic connecting portion 2031 close to the mounting surface. At this time, the positioning portion 2032 can cooperate with the clamping hole 301B, that is, the positioning portion 2032 can be inserted into the clamping hole 301B.

[0062] In an example, as shown in Figures 2 to 5 The second clamping piece 203 can further include a supporting portion 2033 arranged on the end of the elastic connecting portion 2031 close to the mounting surface, and the positioning portion 2032 is arranged on the surface of the supporting portion 2033 away from the elastic connecting portion 2031, so that the positioning portion 2032 is indirectly arranged on the end of the elastic connecting portion 2031 close to the mounting surface by the supporting portion 2033.

[0063] As shown in Figures 2 to 5 Since the elastic connecting portion 2031 is movably arranged on the side surface, the unlocking portion 203B can be arranged on the surface of the elastic connecting portion 2031 away from the side surface. In the initial position, the elastic connecting portion 2031 deforms under the force of the unlocking portion 203B, so that the elastic connecting portion 2031 is separated from the first limiting portion 2011A by the unlocking portion 203B. Therefore, the second clamping piece 203 can be unlocked from the initial position by the unlocking portion 203B; in the target position, the elastic connecting portion 2031 deforms under the force of the unlocking portion 203B, so that the elastic connecting portion 2031 is separated from the second limiting portion 2011B by the unlocking portion 203B. Therefore, the second clamping piece 203 can be unlocked from the target position by the unlocking portion 203B.

[0064] In one example, when the second clamping member 203 is in the initial position, the elastic connecting portion 2031 can be matched with the first limiting portion 2011A on the side surface through the connecting portion 203A. In this way, the positioning portion 2032 is separated from the end of the circuit board 301, so as to prevent the positioning portion 2032 from interfering with the matching between the first clamping member 202 and the slot 301A. When the second clamping member 203 is in the target position, the elastic connecting portion 2031 can be matched with the second limiting portion 2011B on the side surface through the connecting portion 203A, so as to ensure that the end of the positioning portion 2032 can be reliably inserted into the clamping hole 301B on the circuit board 301.

[0065] For example, as shown in Figure 2 , the lock catch is taken as an example, which can be arranged at the position of the elastic connecting portion 2031 facing the side surface, and the unlocking portion 203B includes at least two raised portions extending in the direction away from the side surface. Each of the at least two raised portions is arranged on the elastic connecting portion 2031 along the edge direction of the elastic connecting portion 2031. Figures 2 to 5 Two raised portions are shown in , which are respectively located on both sides of the elastic connecting portion 2031. However, in practice, there can be more raised portions distributed on the edge of the elastic connecting portion 2031.

[0066] Figure 2 For example, as shown in , the two raised portions can be taken as pinch handles. By applying a force, the two raised portions are folded towards the middle of the elastic connecting portion 2031, and the elastic connecting portion 2031 is deformed, so that the lock catch is separated from the first limiting hole or the second limiting hole, thereby conveniently realizing the separation of the second clamping member 203 from the first limiting portion 2011A or the second limiting portion 2011B.

[0067] Figure 5 In an optional way, as shown in Figures 2 to 5 , the side surface of the wind blocking structure 201 further has a guide structure 2012. The second clamping member 203 is arranged on the guide structure 2012, so that the second clamping member 203 moves with the aid of the guide structure 2012. The guide direction of the guide structure 2012 extends along the mounting direction of the air guiding device 200, so that when the second clamping member 203 moves with the aid of the guide structure 2012, the second clamping member 203 can accurately switch between the initial position and the target position.

[0068] Optionally, as shown in Figures 2 to 5 , the side surface further has a limiting track serving as the guide structure 2012. The limiting track extends along the mounting direction of the air guiding device. For example, the limiting track can pass through the wind blocking structure 201, or be a guide groove opened in the wind blocking structure 201.

[0069] AsFigures 2 to 5 As shown in the figure, when the second clamping piece 203 has a guide protrusion 203C on the surface facing the side, the limiting track extends along the installation direction of the air guide device 200, and the guide protrusion 203C is arranged in the limiting track. Therefore, by matching the guide protrusion 203C and the limiting track, the second clamping piece 203 can be guided to move along the installation direction of the air guide device 200 under the guidance of the guide track, so that the second clamping piece 203 can be switched between the initial position and the target position.

[0070] As shown in the figure, Figure 2 The number of limiting tracks can be the same as the number of guide protrusions 203C. For example, the number of limiting tracks is two, and the number of guide protrusions 203C is two. Each guide protrusion 203C is clamped with the corresponding limiting track, so that the guide protrusion 203C can move along the limiting track. When the second clamping piece 203 includes an elastic connecting part 2031 and a positioning part 2032, the guide protrusion 203C can be arranged on the surface of the elastic connecting part 2031 facing the side.

[0071] In an example, as shown in the figure, Figure 5 and Figure 5 The guide protrusion 203C can have a structure with a wide top and a narrow root. At this time, the maximum width of the guide protrusion 203C can be the top width of the guide protrusion 203C, and the minimum width of the guide protrusion 203C is the root width of the guide protrusion 203C. When the guide protrusion 203C and the limiting track are matched, the width direction of the root width and the top width of the guide protrusion 203C can be the track width direction of the limiting track.

[0072] In order to facilitate the disassembly of the guide protrusion 203C, as shown in the figure, Figure 2 The limiting track can include a first track segment 2012A and a second track segment 2012B distributed along the installation direction of the air guide device 200, and the first track segment 2012A and the second track segment 2012B are communicated.

[0073] As shown in the figure, Figure 5 and Figures 2 to 5 The width of the first track segment 2012A is greater than the width of the second track segment 2012B, the width of the first track segment 2012A is greater than or equal to the maximum width of the guide protrusion 203C, the width of the second track segment 2012B is equal to the minimum width of the guide protrusion 203C, and the height of the guide protrusion 203C is greater than the depth of the first track segment 2012A and the second track segment 2012B.

[0074] For example, when the first track segment and the second track segment are both through the wind blocking structure, the top of the guide protrusion 203C can enter the first track segment 2012A from one side of the first track segment 2012A along the depth direction of the first track segment 2012A and extend out from the other side of the first track segment 2012A, while the root of the guide protrusion 203C is located in the first track segment 2012A. At this time, after the guide protrusion 203C is pushed along the mounting direction of the air guide device 200 from the first track segment 2012A to the second track segment 2012B, since the root width (the minimum width of the guide protrusion 203C) of the guide protrusion 203C is equal to the width of the second track segment 2012B, while the top of the guide protrusion 203C is located outside the second track segment 2012B, and the width of the second track segment 2012B is smaller than the top width of the guide protrusion 203C, the guide protrusion 203C will not be separated from the second track segment 2012B along the depth direction of the second track segment 2012B, thereby ensuring that the second clamping piece 203 can be reliably mounted to the side surface of the wind blocking structure 201.

[0075] When it is necessary to remove the second clamping piece from the side surface, on the one hand, the second clamping piece 203 can be separated from the side surface by the unlocking portion 203B, and on the other hand, the second clamping piece 203 can be pushed back to the first track segment 2012A from the second track segment 2012B, and then the guide protrusion 203C can be pulled out from the first track segment 2012A along the depth direction of the first track segment 2012A, so that the guide protrusion 203C is separated from the guide track.

[0076] In a possible implementation, as shown in Figures 2 to 5 The mounting surface can have a guide through hole 2013, and the second clamping piece 203 is arranged in the guide through hole 2013. For example, when the second clamping piece 203 includes the elastic connecting portion 2031 and the positioning portion 2032, the positioning portion 2032 can be arranged in the guide through hole 2013.

[0077] As shown in Figures 2 to 5 When the second clamping piece 203 is switched between the initial position and the target position, the guide through hole 2013 can guide the second clamping piece 203 to prevent the second clamping piece 203 from deviating. For example, when the second clamping piece 203 is moved from the initial position to the target position, the second clamping piece 203 is guided by the guide through hole 2013, so that the end of the second clamping piece 203 towards the circuit board 301 can be accurately inserted into the clamping hole 301B.

[0078] In an optional manner, as shown in Figures 2 to 4As shown, the end of the second latching member 203 facing the circuit board 301 is inserted into the latching hole 301B. The end of the second latching member 203 facing the circuit board 301 may come out of the latching hole 301B. In this case, the distance between the top 302 of the chassis and the top surface of the windproof structure 201 can be set to be relatively short, or the top 302 of the chassis and the top surface of the windproof structure 201 can be aligned to reduce the possibility of the second latching member 203 accidentally coming out of the latching hole 301B, ensuring that the air guide device 200 is reliably installed on the circuit board 301.

[0079] Optional, such as Figure 2 As shown, the windbreak structure 201 has a mounting plate 201A and a top plate 201B. The mounting plate 201A and the top plate 201B can be located on opposite sides of the mounting plate. The mounting plate 201A can have a guide hole 2013. Furthermore, the positioning part 2032 included in the second snap-fit ​​member 203 can pass through the guide hole 2013.

[0080] In the application of the air guide device 200 in a computing device, the mounting plate 201A of the air deflector structure 201 can contact the circuit board 301, and the top plate 201B of the air deflector structure 201 is opposite to the top 302 of the chassis. At this time, the surface of the mounting plate 201A that contacts the circuit board 301 can serve as a mounting surface. When the end of the second snap-fit ​​member 203 facing the circuit board 301 is inserted into the snap-fit ​​hole 301B on the circuit board 301, the positioning portion 2032 of the second snap-fit ​​member 203 facing the circuit board 301 can pass through the guide through hole 2013 and be inserted into the snap-fit ​​hole 301B.

[0081] It should be noted that, as Figure 2 As shown, the limiting structure, guide structure 2012, and guide through hole 2013 provided on the windshield structure 201 of this application embodiment constitute the mounting structure of the second snap-fit ​​member. The mounting structure of the second snap-fit ​​member provided on the windshield structure 201 can be one, two, or more.

[0082] like ​ As shown, when there are multiple mounting structures for the second connectors, the air guide device 200 is applied to the computing device and is mounted on the circuit board 301. In this case, multiple mounting structures for the second connectors are positioned along the front-to-back direction of the chassis on the side of the air baffle structure 201. When it is necessary to change the mounting position of the second connector 203, refer to the previous description to remove the second connector 203 from its current mounting position and then install it in a different mounting position.
