Description

Technical Field

[0001] The present disclosure relates to a housing for electronic components, such as lighting products, speakers, amplifiers, mixers or other electronic components, and more particularly to a ventilated housing with waterproof protection. Background Art

[0002] In the entertainment and architectural lighting and music industries, lamps, speakers and other electronic components are often used outdoors, where there is a risk of rain showers. Therefore, the products should be safely placed under a roof or there should be protection. Summary of the invention

[0003] It is an object of embodiments of the present disclosure to provide an improved housing for an electronic component.

[0004] It is a further object of embodiments of the present disclosure to provide a ventilated housing with waterproof protection.

[0005] The present disclosure provides a housing for an electronic component, the housing comprising:

[0006] - an opening between an external space outside the housing and an internal space inside the housing,

[0007] - an outer surface circumferentially surrounding said opening,

[0008] - a first collar and a second collar, the first collar and the second collar protruding outwardly from the outer surface and extending circumferentially around the opening, the first collar being closer to the opening than the second collar, and the first collar and the second collar being separated by a first space,

[0009] a shielding element comprising a cover and a first edge and a second edge protruding outward from an inner surface of the cover and extending circumferentially around a geometric center of the cover, the first edge being closer to the geometric center than the second edge, and the first edge and the second edge being separated by a second space, and

[0010] a bearing structure located between the inner surface of the cover and the outer surface of the housing and bearing the shielding element at a distance from the outer surface of the housing, so that a passage from the outer space to the inner space is defined between the inner surface of the cover and the outer surface of the housing,

[0011] At least one of the first collar and the second collar overlaps at least one of the first edge and the second edge in a plane perpendicular to the outer surface, and at least one of the first edge and the second edge extends into the first space.

[0012] By providing a first and a second collar protruding outwardly from the outer surface of the housing and the first and the second rim protruding outwardly from the inner surface of the cover, with the shielding element carried at a distance from the outer surface, the opening can be protected from water (such as rain), while a passage through the first and the second collars and the first and the second rim is provided between the interior space and the exterior space to allow ventilation of the interior space. By ventilating the interior space, the risk of condensation in the interior space can be greatly reduced or even avoided.

[0013] To enhance waterproof performance, at least one of the first collar and the second collar overlaps at least one of the first edge and the second edge in a plane perpendicular to the outer surface. This can provide a passage with obstacles for water (such as water flow or water droplets).

[0014] At least one of the first edge and the second edge extends into a first space between the first collar and the second collar. When at least one of the first edge and the second edge extends into the first space between the first collar and the second collar, the channel can form a zigzag path between the inner surface of the cover and the outer surface of the housing.

[0015] In addition, at least one of the first collar and the second collar may extend into a second space provided between the first edge and the second edge. In an alternative embodiment, neither the first collar nor the second collar extends into the second space. This may still provide a blocked passage to reduce the risk of water intrusion.

[0016] The housing may further include a third collar protruding outwardly from the outer surface and extending circumferentially around the opening, wherein the first collar and the second collar may be closer to the opening than the third collar. The third collar arranged circumferentially around the opening and around the first collar and the second collar may provide additional obstruction for a passage from the external space to the internal space.

[0017] The first collar and the second collar may each terminate at a respective free collar end, wherein the first collar and the second collar may each have a height defined as the distance from the outer surface to the respective free collar end. In one embodiment, the first collar and the second collar may have the same height. In alternative embodiments, the height of the first collar may be less than or greater than the height of the second collar.

[0018] The first edge and the second edge may each terminate at a corresponding free edge end, wherein the first edge and the second edge may each have a height defined as the distance from the inner surface of the lid to the corresponding free edge end. In one embodiment, the height of the second edge may be greater than the height of the first edge. This may ensure greater overlap between the second edge and the second collar to provide a greater blockage closer to the external space. In an alternative embodiment, the first edge and the second edge may have the same height.

[0019] The third collar may extend towards the second edge, wherein the third collar and the second edge may be aligned along a longitudinal direction of the third collar and the second edge. The third collar and the second edge may define a common surface, which may define an outer boundary of the shielding element. The free end of the third collar and the free end of the second edge may be arranged at a distance from each other to provide an entrance to the passage.

[0020] The second collar may include at least one drain port to provide drainage from the first space to the external space via the at least one drain port. If water intrusion cannot be completely avoided, water can be discharged from the first space via the at least one drain port. In one embodiment, when the second collar forms a non-circular shape on a cross section parallel to the outer surface, the at least one drain port may be arranged at the corner of the second collar, such as at each corner. Therefore, in an embodiment in which the second collar is substantially square on a cross section parallel to the outer surface, the drain port may be arranged on one or more of the corners.

[0021] At least one wall portion may extend outwardly from the second collar along at least one drain opening to provide a flow guide toward the exterior space. By providing a flow guide, flow toward the exterior space may be promoted while at least partially obstructing water flow in the opposite direction.

[0022] In one embodiment, the cover may include at least one aperture to provide a passage through the cover. The aperture may have a circular hole, a triangular hole, a substantially C-shaped hole, a U-shaped hole, or other shapes in a cross section parallel to the inner surface of the cover.

[0023] The housing may further include a substrate forming the second opening. The substrate may be attached to the outer surface so that the second opening is aligned with the opening to ensure that the opening is not blocked by the substrate. The first collar and the second collar may form part of the substrate, and the substrate may be arranged so that the first collar and the second collar protrude outwardly from the outer surface of the housing.

[0024] By providing the first collar and the second collar on the base plate, the base plate can form a separate structure together with the shielding element, and the separate structure together with the bearing structure can be easily replaced. In addition, it can also be used to protect the inner space of an existing housing with an opening.

[0025] The housing may further include a filter element that may be located in the first housing surrounded by the first collar. The filter element may extend transversely to the opening to protect the interior space of the housing. The filter element may be configured to remove, for example, dust, pollen, and other unwanted matter.

[0026] The housing may further include an absorbent element attached to the inner surface of the lid. The absorbent element may be located in the second shell surrounded by the first edge. The absorbent element 162 may be arranged to absorb droplets and / or moisture to reduce the risk of moisture intrusion into the interior space. In one embodiment, the absorbent element may be a piece of felt, such as a felt made of natural and / or synthetic fibers.

[0027] The housing may also include a fan unit in the interior space, wherein the fan unit may be configured to provide an airflow between the exterior space and the interior space. The airflow provided may help ventilate the interior space to reduce the risk of damaging electronic components due to condensation. The airflow may also be used to compensate for pressure losses on a filter element that may be arranged transversely to the opening. In addition, the airflow may be used to remove heat generated by the electronic components in the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] It should be understood that the detailed description and specific embodiments, while indicating embodiments of the disclosure, are given by way of illustration only since various changes and modifications within the scope of the disclosure will become apparent to those skilled in the art from this detailed description.

[0037] Figure 1 and Figure 2 A housing 100 for an electronic component E is shown. Figure 1 , the housing 100 is shown in an exploded view, and Figure 2 A cross section through the housing 100 is shown.

[0038] The electronic component E may be, for example, a lighting product, a loudspeaker, an amplifier, a mixer or other electronic component. In the embodiment shown, the electronic component E is in the form of a power supply.

[0039] The housing 100 includes an opening 102 between an external space 104 outside the housing 100 and an internal space 106 inside the housing 100. The housing 100 may be Figure 1 However, in alternative embodiments, housing 100 may be tubular, or the cross-section may be triangular, oval, or any other shape.

[0040] The housing 100 includes an outer surface 108 circumferentially surrounding the opening 102. In the illustrated embodiment, the opening 102 is provided in the outer surface 108 of one of the four walls forming the housing. The housing 100 may be formed by an upper portion 108A and a lower portion 108B, wherein the outer surface 108 may be the outer surface of the upper portion 108A or the lower portion 108B. The lower portion 108B forms a tray-shaped element in which the power source E is arranged.

[0041] The opening 102 may be circular, rectangular, oval, triangular or any other shape. In the embodiment shown, the opening 102 is circular.

[0042] The first and second loops 110, 112 protrude outwardly from the outer surface 108. In the illustrated embodiment, the first and second loops 110, 112 extend substantially perpendicularly from the outer surface 108. In alternative embodiments, the first and second loops 110, 112 may extend from the outer surface 108 at an angle to the perpendicular, such as up to + / - 25 degrees from the perpendicular.

[0043] The first and second collars 110, 112 extend circumferentially around the opening 102 (see Figure 3 and Figure 6 ), wherein the first collar 110 is closer to the opening 102 than the second collar 112. The first collar 112 and the second collar 112 are separated by a first space 114.

[0044] In the illustrated embodiment, the cross-section of the first and second loops 110, 112 along the outer surface 108 is substantially rectangular. Thus, the first and second loops 110, 112 have another shape than the circular shape of the opening 102. In alternative embodiments, the cross-sectional shape of the first and second loops 110, 112 may have the same shape as the opening 102. In further alternatives, the cross-sectional shape of the first loop 110 may be different than the cross-sectional shape of the second loop 112.

[0045] The housing 110 may further include a base plate 116 forming a second opening 118. The base plate 116 may be attached to the outer surface 108 such that the second opening 118 is aligned with the opening 102. The first collar 110 and the second collar 112 may form a portion of the base plate 116. The base plate 116 and the first collar 110 and the second collar 112 may be formed as a single piece, for example, by molding. Alternatively, the first collar 110 and the second collar 112 may be formed as separate elements, which may then be attached to the base plate 116. Thus, the first collar 110 and the second collar 112 may protrude outwardly from the outer surface 108 while forming a portion of the base plate 116 attached to the outer surface 108.

[0046] The housing 100 further includes a shielding element 120, which can be arranged to at least partially shield the opening 102 to prevent rain from falling on the housing. The shielding element 120 includes a cover 122 and a first edge 124 and a second edge 126 protruding outward from an inner surface 128 of the cover 122 (see Figure 2 The shielding element 120 may be arranged with the inner surface 128 facing the opening 102 .

[0047] The first edge 124 and the second edge 126 extend circumferentially around the geometric center C of the cover 122 (see Figure 7 ), wherein the first edge 124 is closer to the geometric center C than the second edge 126. The first edge 124 and the second edge 126 are separated by a second space 130.

[0048] The bearing structures 132A, 132B, 132C are arranged between the inner surface 128 of the cover 122 and the outer surface 108 of the housing 100. The bearing structures 132A, 132B, 132C bear the shielding element 120 at a distance from the outer surface 108 of the housing 100, thereby defining a passage 134 from the outer space 104 to the inner space 106 between the inner surface 128 of the cover 122 and the outer surface 108 of the housing 100 (see Figure 2 ).exist Figure 2When the support structure 132 is disposed between the inner surface 128 of the cover 12 and the outer surface 108 of the housing 100 , the first edge 124 and the second edge 126 extend toward the outer surface 108 .

[0049] By providing a first collar 110 and a second collar 112 protruding outwardly from the outer surface 108 of the housing 100 and a first rim 124 and a second rim 126 protruding outwardly from the inner surface 128 of the cover 122, the opening 102 can be protected from rain when the shielding element 120 is carried at a distance from the outer surface 108, while providing a passage 134 through the first collar 110 and the second collar 112 and the first rim 124 and the second rim 126 between the interior space 106 and the exterior space 104 to allow ventilation of the interior space 106. Ventilation of the interior space 106 can reduce or even avoid the risk of condensation in the interior space 106.

[0050] In the illustrated embodiment, the support structure 132 includes four bolts 132A, each of which has an external thread that engages with an internal thread of a tubular support member 132B (see FIG. Figure 7 ). The four tubular carriers 132B are arranged between the base plate 116 and the inner surface 128 of the cover 122. In an alternative embodiment, the tubular carriers 132B may be arranged on the outer surface 108.

[0051] In a further alternative, the carrying structure 132 may include matching structures 132A, 132B, wherein one matching structure 132B may be attached to the outer surface 108, and the corresponding matching structure 132A may form a part of or be attached to the shield element 120. The carrying structure 132 may, for example, include a snap-fit ​​structure, a geometric locking structure that is attached to each other by friction, or other locking structure.

[0052] By providing a bearing structure 132 that carries the shielding element 120 at a certain distance from the outer surface 108 of the shell 100, a channel 134 from the outer space 104 to the inner space 106 is defined between the inner surface 128 of the cover 122 and the outer surface 108 of the shell 100. Air can ventilate the inner space 106 via the channel 134, and the air flow can have reduced pressure loss because the first collar 110 and the second collar 112 extend circumferentially around the opening 102, and because the first edge 124 and the second edge 126 extend circumferentially around the geometric center C of the cover, thereby providing a larger channel 134 area while preventing rain from falling on the shell 110.

[0053] like Figure 2As shown, the first collar 110 and the second collar 112 may overlap the first edge 124 and the second edge 126 in a plane perpendicular to the outer surface 108 . Figure 2 The overlapping portions O1, O2 are indicated by arrows in FIG. In the illustrated embodiment, the first overlapping portion O1 between the second collar 112 and the second rim 126 is greater than the second overlapping portion O2 between the first collars 110, 112 and the first rim 124. By providing one or more overlapping portions O1, O2 between at least some of the first collar 110 and the second collar 112 and the first edge 124 and the second edge 126, the channel 134 can be better protected from rain falling on the housing 100.

[0054] The first collar 110 and the second collar 112 are separated by a first space 114. In the illustrated embodiment, the first rim 124 extends into the first space 114, which can provide blocking of the channel 134 to further protect the channel 134 from water flow while allowing air to flow through the channel 134 to ventilate the interior space 106.

[0055] The first rim 124 and the second rim 126 are separated by a second space 130. In the illustrated embodiment, the first collar 110 extends into the second space 130. This may further enhance the protection of the channel 134 from water flow.

[0056] The housing 110 may further include a third collar 136 that projects outwardly from the outer surface 108 and extends circumferentially around the opening 102, such as Figure 1 102. The first and second collars 110, 112 may be closer to the opening 102 than the third collar 136, which may be arranged as the outermost collar. The third collar 136 may be arranged along the outer edge 138 of the substrate 116. The third collar 136 may further enhance the protection against water intrusion into the interior space 106. In various embodiments, one or more additional collars may be arranged circumferentially around the opening 102 and around the first and second collars 110, 112.

[0057] The third loop 136 may extend toward the second rim 126, and the third loop 136 and the second rim 126 may be aligned along a longitudinal direction of the third loop and the second rim, wherein the longitudinal direction may be defined as a direction in which the third loop 136 and the second rim 126 have their largest dimensions. The distance between the free loop end 140 and the free rim end 142 may be in the range of 1-5 mm, such as in the range of 2-3 mm.

[0058] The first, second, and third collars 110, 112, and 136 may terminate at respective free collar ends 140. The first, second, and third collars 110, 112, and 136 may each have a height defined as the distance from the outer surface 108 of the housing 100 to its respective free collar end 140. In the illustrated embodiment, the heights of the first and second collars 110, 112 are substantially the same, while the height of the third collar 136 is smaller. In alternative embodiments, the height of each of the collars 110, 112, 136 may be the same, while in further alternatives, the height of each of the collars 110, 112, 136 may all be different. The heights of the first, second, and third collars 110, 112, and 136 may be in the range of 2-20 mm, such as 2-10 mm, such as 2-8 mm.

[0059] The first edge 124 and the second edge 126 may terminate at a respective free edge end 142. The first edge 124 and the second edge 126 may each have a height defined as the distance from the inner surface 128 of the cover 122 to its respective free edge end 142. The height of the second edge 126 may be greater than the height of the first edge 124. In an alternative embodiment, the first edge 124 and the second edge 126 may have substantially the same height. The height of the first edge 124 and the second edge 126 may be in the range of 2-20 mm, such as 2-10 mm, such as 2-8 mm. The height of the collar 110, 112, 136 and the height of the edges 124, 126 may depend on the size of the housing 100 and / or the size of the opening 102 and / or the distance from the collar / edge to the center of the opening.

[0060] Figure 3 Shows Figure 1 and Figure 2 The parts of the housing 100 are also shown. Figure 3 In the embodiment, the shielding element 120 (see Figure 1 and Figure 2 ) has been removed. Figure 4 The housing 100 is shown, wherein the shield element 120 is arranged in front of the opening 102 at a distance from the outer surface 108 , thereby defining a passage 134 from the outer space 104 to the inner space 106 . Figure 4 Only the inlet 134A of the channel 134 is shown. The inlet 134A may extend along the entire circumference of the shielding element 120.

[0061] Figure 3 A first collar 110 and a second collar 112 are shown protruding outwardly from the outer surface 108 and extending circumferentially around the opening 102 , wherein the first collar 110 is closer to the opening 102 than the second collar 110 , and wherein the first collar 110 and the second collar 112 are separated by a first space 114 .

[0062] In the illustrated embodiment, the second collar 112 includes four drain ports 144 (see also Figure 6 ) to provide drainage from the first space 114 to the exterior space 104 via the drain openings 144. A drain opening 144 is positioned at each corner 146 of the second collar 112. By providing one or more drain openings, water in the first space 114 may be able to drain if the first and second collars 110, 112 and the first and second edges 124, 126 do not completely prevent water from entering the first space 114. The drain openings 144 may also provide the possibility of having a second collar 112 whose height is greater than or the same as the height of the first collar 110.

[0063] To facilitate flow in a direction from the first space 114 toward the exterior space 104, at least one wall portion 148 may extend outwardly from the second collar 112 along at least one drain opening 144 to provide flow guidance toward the exterior space 104. In the illustrated embodiment, the wall portions 148 extending outwardly from the second collar 112 are arranged along each drain opening 144 along opposite sides of the drain opening 144. This may increase flow guidance toward the exterior space 104 while at least partially obstructing water flow in the opposite direction.

[0064] In the illustrated embodiment, four openings 132C having internal threads are arranged in the base plate 116 for engaging with the bolts 132A to form a part of the load-bearing structure 132. The four openings 132C may be arranged outside the first space between the second collar 112 and the third collar 136.

[0065] like Figure 4 As shown, the cover 122 may include at least one aperture 150 to provide a passage through the cover 122. In the illustrated embodiment, a C-shaped aperture 150 is provided in each corner of the cover in an area adjacent to the bolt 132A. The aperture 150 may be arranged to provide drainage from the inner surface 128 of the cover 122 to the exterior space 104. The aperture 150 may be provided with a flow guide structure similar to the wall portion 148 to promote water flow toward the exterior space 104 and partially hinder flow in the opposite direction.

[0066] Figure 5 Shows Figure 1 and Figure 2 The parts of the housing 100 are also shown. Figure 5 In the embodiment, the shielding element 120 (see Figure 1 and Figure 2 ) has been removed, providing the same Figure 3 The housing 100 may also include a filter element 152 (see Figure 1), the filter element is located in a first housing 154 surrounded by a first collar 110 (see Figure 3 ) The size of the filter element 152 can be adapted to the size of the first housing 154. Since the filter element 152 is inserted into the first housing 154, the first housing is Figure 5 Not visible in.

[0067] The filter element 152 may have a height corresponding to the height of the first collar 110 to allow the filter element 152 to be fully inserted into the first housing 154. The filter element 152 may be configured to remove dust and may extend transversely to the opening 102 to minimize the risk of dust, pollen and other unwanted matter being carried into the interior space 106 with the airflow.

[0068] In the illustrated embodiment, the filter element 152 includes a plurality of sheets 156 forming a zigzag pattern. In alternative embodiments, the filter element 152 can be a foam element. Other types of filter elements 152 can also be used.

[0069] The housing 100 may further include a fan unit 160 located in the interior space 106 (see also Figure 1 and Figure 3 The fan unit 160 may be configured to provide airflow between the external space 104 and the internal space 106. The fan unit 160 may be configured to provide airflow from the internal space 106 to the external space 104 and / or to provide airflow from the external space 104 to the internal space 106.

[0070] The airflow provided by the fan unit 160 can help ventilate the interior space 106 to reduce the risk of damaging the electronic components due to condensation. The airflow can also be used to compensate for pressure losses on the filter element 152 that can be arranged transversely to the opening 102.

[0071] Figure 6 The housing 100 is shown without the cover 122 as viewed from above (see, for example, Figure 1 ). The top view shows that the first collar 110 and the second collar 112 protrude outwardly from the outer surface 108 of the housing 100 and extend circumferentially around the opening 102. In the illustrated embodiment, the first collar 110 and the second collar 112 are attached to the base plate 116. The housing 100 may include a third collar 136 protruding outwardly from the outer surface 108 and extending circumferentially around the opening 102, wherein the first collar 110 and the second collar 112 are disposed closer to the opening 102 than the third collar 136.

[0072] Four drains 144 are arranged to provide drainage from the first space 114 to the exterior space 104 via the drains 144. Wall portions 148 extending outwardly from the second collar 112 are arranged at each drain 144 along opposite sides of the drain 144. This can increase flow guidance toward the exterior space 104 while at least partially obstructing water flow in the opposite direction toward the first space 114.

[0073] Figure 7 The cover 122 is shown from below. The cover 122 forms a portion of the housing 100. The view from below shows that the first rim 124 and the second rim 126 protrude outwardly from the inner surface 128 of the cover 122 and extend circumferentially around the geometric center C of the cover 122.

[0074] The housing 100 may also include an absorbent element 162 attached to the inner surface 128 of the cover 122. The absorbent element 162 may be located in a second housing 164 surrounded by the first rim 124. The size of the absorbent element 162 may be adapted to the size of the second housing 164. Alternatively, the absorbent element 162 may occupy only a portion of the space of the second housing 164.

[0075] The absorbent element 162 may be a piece of felt, such as felt made of natural and / or synthetic fibers. The absorbent element 162 may be arranged on the inner surface 128 to absorb droplets and / or moisture to reduce the risk of their intrusion into the interior space 106.
