Example one

In an embodiment of the present invention, an air intake assembly is provided, and referring to fig. 1 to 6, the air intake assembly 1 may include:

the side sealing plate 11 encloses a hollow space 14, and the side sealing plate 11 is provided with a through hole 111 penetrating through the accommodating space 15 and an outer space 16 of the side sealing plate 11;

the partition plate 12, the edge of the partition plate 12 and the side sealing plate 11 are connected to form a containing space 15 under the partition plate 12; and

and an airflow conducting assembly 13, wherein the airflow conducting assembly 13 is at least partially arranged above the accommodating space 15, and an airflow guide channel 131 penetrating the upper space 17 of the partition plate 12 and the accommodating space 15 is formed, so that the airflow entering the accommodating space 15 from the outer space 16 through the through hole 111 can flow out from the airflow guide channel 131 to the upper space 17 of the partition plate 12.

Depending on the shape and manufacturing process, the side sealing plate 11 in the embodiment of the present invention may refer to a plurality of different side sealing plates (e.g., side sealing plates that enclose each side of a prism), or may refer to an integral plate (e.g., an arc-shaped side sealing plate that encloses a cylinder); different side sealing plates 11 may be formed separately or integrally by forming a plurality of side sealing plates, which is not limited in the embodiment of the present invention, and the shape of the side sealing plate 11 is also not limited, for example, it may be a flat plate, or an arc panel, etc.

In a specific implementation, part of the edges of the partition plates 12 are connected to the side seal plates 11, or all the edges of the partition plates 12 are connected to the side seal plates 11, which may be in a direct connection manner or an indirect connection manner, and this is not limited in this embodiment of the present invention.

The hollow space 14 surrounded by the side sealing plates 11 may be formed in various shapes according to the shape of the side sealing plates 11. The receiving space 15 defined by the side sealing plate 11 and the partition plate 12 and located below the partition plate 12 may be formed in various shapes according to the shape of the side sealing plate 11 and the shape of the partition plate 12, and the embodiment of the present invention is not particularly limited thereto.

The receiving space 15 is defined by the inner surfaces of the side sealing plates 11 and the partition plate 12.

The through hole 111 in the embodiment of the present invention is a hole penetrating the accommodating space 15 and the outer space 16 of the side sealing plate 11 to achieve the purpose of air intake and heat dissipation. The number, shape, depth, opening size, etc. of the through holes 111 are not limited in the embodiments of the present invention. For example, various existing design shapes such as circular, various polygonal, funnel-shaped, etc. may be used. The number of the through holes 111 is as large as possible on the premise that the ventilation amount required for heat dissipation is satisfied.

If the side cover plate 11 is integrally formed, through holes 111 for ventilation may be formed in a partial region of the side cover plate 11, and the through holes 111 for ventilation may not be formed in other regions.

The airflow conducting assembly 13 may be partially located above the accommodating space 15, and partially located in the accommodating space 15; alternatively, the airflow conducting assembly 13 is entirely located above the accommodating space 15, which is not limited in the embodiment of the present invention.

The airflow conducting assembly 13 in the embodiment of the invention is at least partially disposed above the accommodating space 15, and the airflow guide channel 131 is formed to communicate the accommodating space 15 with the upper space 17 of the partition plate 12, so that the airflow entering the accommodating space 15 from the outer space 16 through the through hole 111 can flow out from the airflow guide channel 131 to the upper space 17 of the partition plate 12. After entering the receiving space 15 through the through hole 111, the airflow is blocked by the partition plate 12 when rising, and after moving laterally, the airflow is guided to rise above the receiving space 15 by the airflow conducting assembly 13 at least partially disposed above the receiving space 15.

In a state where the intake module 1 is mounted to the signal shielding device, the upper space 17 of the partition plate 12 is generally a space for accommodating electronic components; the structure of the air inlet assembly 1 can lead the air flow to take away heat in the state that the air inlet assembly 1 is assembled in the signal shielding device, and meanwhile, the accommodating space 15 formed by the side sealing plates 11 and the partition plates 12 can block larger water drops from entering the upper space 17 provided with electronic components; on the other hand, because the original flowing direction of the airflow is changed by the partition plate 12 and the airflow conducting assembly 13, the stroke of the airflow is increased in the process of guiding the airflow to rise, so that small water drops carried in the airflow are settled under the influence of self gravity factors, and good air inlet heat dissipation and waterproof effects are achieved.

In an alternative embodiment, referring to fig. 2 and 3, the airflow guiding assembly 13 may include two blocking portions 132 extending at least partially into the accommodating space 15 in the height direction, the two blocking portions 132 are disposed opposite to and spaced apart from each other, the blocking portions 132 are disposed facing the through hole 111, and the airflow guiding channel 131 includes a spaced region between the two blocking portions 132, so that the external airflow entering from the through hole 111 bypasses the blocking portions 132, enters the airflow guiding channel 131, and flows out from the airflow guiding channel 131 to the upper space 17 of the partition 12.

The blocking portion 132 in the embodiment of the present invention may be disposed in the receiving space 15 (disposed on the bottom sealing plate) as shown in fig. 2, or may be connected to the partition plate 12 and extend toward the receiving space 15 as shown in fig. 3, in order to isolate the through hole 111 and the air flow guide passage 131 at the corresponding positions. On the one hand, the blocking portion 132 directly blocks the water droplets entering through the through-hole 111 from entering through the air flow guide passage 131 into the upper space 17 equipped with the electronic component; on the other hand, the blocking part 132 changes the original flowing direction of the airflow and increases the stroke of the airflow in the process of guiding the airflow to rise, so that smaller water drops carried in the airflow settle under the influence of self gravity factors, and better air inlet heat dissipation and waterproof effects are achieved.

Referring to fig. 2, the gap 121 formed in the partition 12 and the spacing region between the two blocking portions 132 are used as a part of the airflow guide channel 131; referring to fig. 3, the gap 121 or gap between adjacent partitions 12 and the spacing region between two blocking portions 132 extending from the edge of the partition 12 to the receiving space 15 are used as a part of the airflow guide channel 131. The blocking portion 132 may be a flat plate or an arc plate, and the specific structure and the arrangement position of the blocking portion 132 are not particularly limited in the embodiment of the present invention.

In another alternative embodiment, referring to fig. 4 and 5, the airflow conducting assembly 13 at least includes a hollow cylindrical member 133, and the cylindrical member 133 is connected to the partition 12 and at least partially extends into the receiving space 15 in the height direction.

The partition plate 12 and the columnar member 133 of the airflow directing assembly 13 in the embodiment of the present invention may be in a split type structure and assembled together, or may be in an integrally formed structure, which is not particularly limited in the embodiment of the present invention.

The hollow portion of the column-shaped member 133 in the embodiment of the present invention constitutes at least a part of the airflow guide channel 131, the column-shaped member 133 is connected to the partition 12, and the notch 121 surrounded by the inner wall of the notch 121 opened in advance in the partition 12 also constitutes at least a part of the airflow guide channel 131. The air flow entering the receiving space 15 through the through hole 111 flows out from the hollow portion of the columnar member 133 to the upper space 17 of the partition plate 12, and one or more of the columnar members 133 may be designed according to the requirement of the intake air amount, which is not particularly limited in the embodiment of the present invention.

The columnar member 133 may be a hollow prism-shaped structure or a hollow cylindrical structure, and the upper end and the bottom end of the columnar member 133 may be open, so that the air flow enters the hollow part from the bottom of the columnar member 133; the bottom end may be closed and the upper end may be opened, and the air flow enters the hollow portion through the guiding holes 1332 on the side wall 1331 of the cylindrical member 133, which is not particularly limited in the embodiment of the present invention.

The sidewall 1331 of the column-shaped member 133 extending in the height direction of the accommodating space 15 in the embodiment of the present invention separates the through hole 111 from the airflow guiding channel 131, water drops in the airflow entering the accommodating space 15 from the through hole 111 naturally settle down into the accommodating space 15, and water drops splashed into the accommodating space 15 from the through hole 111 are blocked by the sidewall 1331 and cannot directly enter the airflow guiding channel 131.

Moreover, due to the obstruction of the side wall 1331 to the airflow path, the airflow enters the hollow part of the cylindrical member 133 from the bottom of the cylindrical member 133 or the flow guide holes 1332 on the side wall 1331, so that the stroke of the airflow is increased, more water drops in the airflow are promoted to naturally settle, and the waterproof effect is better improved.

In another alternative embodiment, referring to fig. 4 and 5, the side sealing plates 11 may include a first side sealing plate 112 and a second side sealing plate 113, the side wall 1331 of the cylindrical member 133 has at least one guiding hole 1332, the through hole 111 is formed in the first side sealing plate 112, the guiding hole 1332 faces the second side sealing plate 113, and the first side sealing plate 112 and the second side sealing plate 113 are connected and face in different directions.

For the sake of clarity, the side cover plates 11 facing different directions are referred to as a first side cover plate 112 and a second side cover plate 113, respectively, and the structure thereof is not limited.

The guiding hole 1332 of the embodiment of the invention can guide the airflow from the accommodating space 15 to the hollow portion (a portion of the airflow guiding channel) of the cylindrical member 133 through the guiding hole 1332, and the guiding hole 1332 can effectively guide the flowing direction of the airflow.

Further, the guiding hole 1332 of the embodiment of the present invention faces the second side sealing plate 113, so that the guiding hole 1332 and the through hole 111 are in different directions, the guiding hole 1332 and the through hole 111 cannot be directly communicated, the air flow entering the accommodating space 15 from the through hole 111 needs to be diverted at least once to enter the hollow portion of the cylindrical member 133 from the guiding hole 1332, and the air flow stroke is increased during the diverting process, so that the water drops carried in the air flow further settle.

In one particular embodiment, and as shown in fig. 4 and 5, the first side closure panel 112 and the second side closure panel 113 are oriented perpendicular to each other.

In the embodiment of the present invention, the through hole 111 is disposed on the first side sealing plate 112, and the guiding hole 1332 faces the second side sealing plate 113, so that the guiding hole 1332 and the through hole 111 are open in different directions. Under the condition that the orientation of first side shrouding 112 and the orientation mutually perpendicular of second side shrouding 113, the opening orientation of water conservancy diversion hole 1332 is also mutually perpendicular with the opening orientation of through-hole 111, and the air current that gets into to holding space 15 from through-hole 111 needs the angle of a vertical direction of conversion just can enter into the hollow part of column component 133 through water conservancy diversion hole 1332, has increased the gas stroke in this process, reaches better water droplet and subsides the effect, has promoted air intake assembly 1's water-proof effects.

Referring to fig. 4 and 5, side sealing plates 11 may include two oppositely disposed first side sealing plates 112 and two oppositely disposed second side sealing plates 113, where first side sealing plate 112 and second side sealing plate 113 are sequentially connected to form hollow space 14.

The first side sealing plate 112 and the second side sealing plate 113 in the embodiment of the present invention may be integrally formed or may be separately connected to each other, and the embodiment of the present invention is not limited thereto.

In another embodiment, as shown in fig. 4 and 5, the second side sealing plate 113 is not provided with the through hole 111 for air flow; the guiding holes 1332 face the second side sealing plate 113.

In the embodiment of the present invention, the second side sealing plate 113 is not provided with the through hole 111 for air flow circulation, so that the opening directions of the guiding hole 1332 and the through hole 111 are different, the guiding hole 1332 and the through hole 111 cannot be directly communicated, and the air flow can flow out of the guiding hole 1332 only after at least one reversing.

It should be noted that the second side sealing plate 113 may be provided with through holes for fixing other elements, but when other elements are fixed by screws, the through holes for fixing other elements are no longer communicated with the outer space 16 and the accommodating space 15.

As shown in fig. 4 and 5, the whole air intake assembly 1 is in a rectangular parallelepiped shape or a shape similar to a rectangular parallelepiped, the side sealing plate disposed in the longitudinal direction is the first side sealing plate 112, the side sealing plate disposed in the width direction is the second side sealing plate 113, the through hole 111 formed in the first side sealing plate 112 disposed opposite to the through hole 111 is used for air intake, and the guiding hole 1332 faces the second side sealing plate 113 where the through hole 111 is not formed. By the design, on one hand, the number of the through holes 111 is enough to meet the requirement of air inflow required by ventilation and heat dissipation; on the other hand, when the air inlet assembly 1 is assembled in the signal shielding device, water drops can be prevented from entering the portable signal shielding device through the opening of the airflow conducting assembly 13.

In another alternative embodiment, referring to fig. 4 and 5, the column member 133 is prism-shaped, wherein the sidewall 1331 without the flow guide hole faces the first side sealing plate 112 with the through hole 111.

In the present embodiment, the sidewall 1331 without the flow guide hole is used as the blocking portion 132 of the airflow communication assembly 13, and is disposed facing the first side sealing plate 112 with the through hole 111, so that the external airflow entering from the through hole 111 bypasses the blocking portion 132, enters the airflow guide channel 131, and flows out from the airflow guide channel 131 to the upper space 17 of the partition 12.

In another alternative embodiment, the side sealing plates 11 include at least two second side sealing plates 113 disposed oppositely; the number of the guiding holes 1332 is at least two, and the guiding holes respectively face the second side sealing plates 113 which are oppositely arranged and not provided with the through holes 111.

In order to better guide the flow of the air flow, in another alternative embodiment, as shown in fig. 4 and 5, the air intake assembly 1 may further include: one end of the tubular flow guiding element 134 is connected to the flow guiding hole 1332, and the other end of the flow guiding element 134 faces the second side sealing plate 113 that is not provided with the through hole 111.

The flow guide 134 may be disposed in a vertical direction (i.e., horizontally) with respect to the columnar member 133; of course, it will be appreciated by those skilled in the art that the column member 133 may be disposed obliquely.

The tubular flow guiding element 134 in the embodiment of the present invention may be a straight tubular element, or may be at least partially bent, and this is not particularly limited in the embodiment of the present invention.

Referring to fig. 4, the flow guide 134 has a straight tubular shape, and a central axis of the flow guide 134 is parallel to the first side cover plate 112 where the through hole 111 is located.

In one specific embodiment, as shown in fig. 4 and 5, the cylindrical member 133 has a closed bottom 1333, and the upper end of the cylindrical member 133 is open.

The above intake assembly 1 may further include: a bottom sealing plate 18 connected to the side sealing plate 11; the bottom sealing plate 18 is provided with a positioning groove 181 or a positioning hole 181;

the bottom 1333 of the columnar member 133 is provided with a protrusion 1334 adapted to the positioning groove 181 and/or the positioning hole 181, and the protrusion 1334 is clamped in the positioning groove 181 or the positioning hole 181.

In the embodiment of the present invention, the protrusion 1334 and the positioning groove 181/positioning hole 181 are two parts that are matched with each other, and the columnar member 133 can be quickly positioned by the protrusion 1334 and the positioning groove 181/positioning hole 181, so that the installation of the columnar member 133 is facilitated, and the structure after the installation is more stable. If the partition plate 12 and the airflow guiding component 13 in the embodiment of the present invention are integrally formed, the protrusion 1334 enables the partition plate 12 and the airflow guiding component 13 to be quickly assembled in the accommodating space 15.

In a specific implementation, the positioning groove 181 may be a oval shape, and the oval structure facilitates quick positioning and alignment of the protrusion 1334, so as to improve assembly efficiency.

In a specific embodiment, as shown with reference to fig. 4 and 5, the intake assembly 1 may further include: a bottom sealing plate 18 connected to the side sealing plate 11; the bottom sealing plate 18 is provided with a water outlet 182.

In the air intake assembly 1 of the embodiment of the present invention, the bottom sealing plate 18 is usually located at the lowest end of the air intake assembly 1 in the normal use state of the portable signal shielding device. Therefore, the water outlet 182 is formed in the bottom sealing plate 18, so that water drops entering the air intake assembly 1 can be gathered on the bottom sealing plate 18 and can be discharged in time.

In an alternative embodiment, referring to fig. 6, the bottom sealing plate 18 is provided with a drainage groove 183, and the outlet hole 182 is located in the drainage groove 183.

The inventors have found that the amount of water droplets entering the interior of the air inlet assembly is small, and after the water droplets settle on the bottom sealing plate 18, the accumulated water is not easily discharged through the water outlet 182 due to the water tension acting on the surface of the bottom sealing plate 18 to form a water film. Therefore, in the structure of the drainage channel 183 and the water outlet 182, the accumulated water is firstly collected in the drainage channel 183 and then flows into the water outlet 182 to be discharged. The drainage groove 183 may have any shape as long as it can collect water droplets, for example, as shown in fig. 6, the drainage groove 183 may be parallel to the first side cover plate 112 in the longitudinal direction, or perpendicular to the first side cover plate 112 in the longitudinal direction, and the cross-sectional shape of the drainage groove 183 may be U-shaped or V-shaped, and the specific structure and position of the drainage groove 183 are not limited in the embodiment of the present invention.

In the embodiment of the present invention, in order to ensure sufficient ventilation to achieve a better ventilation and heat dissipation effect, as many through holes 111 as possible need to be formed in the side sealing plates 11, if the two end portions of the supporting beam 19 are completely attached to the two opposite side sealing plates 11 in height, the side sealing plates 11 cannot open holes at the connecting portions, and the number of the through holes 111 will be reduced to a certain extent.

In an alternative embodiment, referring to fig. 4 and 5, the air intake assembly includes two air flow guiding assemblies 13 respectively disposed on two sides of the supporting beam 19, for example, symmetrically disposed with respect to the supporting beam 19, so as to make the overall structure of the air intake assembly 1 more stable.
