[0005] [Patent Document 1] Japanese Patent No. 4189256 Utility Model Content

[0006] [The problem that the utility model aims to solve]

[0007] However, as wireless communication devices become more high-performance, they generate more heat, increasing the need for heat dissipation.

[0008] This invention was made in view of the aforementioned issues, and its main objective is to provide a wireless communication component and wireless communication unit that can improve heat dissipation.

[0009] [Technical means to solve the problem]

[0010] To address the aforementioned issues, one embodiment of the present invention provides a wireless communication component comprising: a base unit mounted on a ceiling and having a first connector; and a wireless communication unit configured to be detachable from the base unit and having a second connector that connects to the first connector when mounted on the base unit, operating via power supplied through the first connector and the second connector. The base unit is mounted on the edge of a hole formed in the ceiling, and when mounted on the base unit, at least a portion of the wireless communication unit is located inside the hole in the ceiling. This improves heat dissipation.

[0011] In this configuration, the wireless communication unit can connect to the wired network via data transmission through the first connector and the second connector. Accordingly, both power supply and data transmission can be performed via the connectors, thus simplifying the construction of the wireless communication area.

[0012] In this configuration, the base unit may have an insertion hole located inside the hole in the ceiling, and the wireless communication unit may have an insertion part that inserts into the insertion hole. Accordingly, the insertion part can be inserted into the insertion hole, thereby improving heat dissipation.

[0013] In this configuration, the insertion hole of the base unit and the insertion portion of the wireless communication unit may have a shape that is symmetrical about one revolution around the insertion direction. This helps to suppress accidental insertion.

[0014] In this configuration, the connection direction of the first connector and the second connector can be the same as the insertion direction of the insertion hole of the base unit and the insertion part of the wireless communication unit. Therefore, the connection of the connectors can be completed simultaneously with the insertion of the insertion part.

[0015] In this configuration, the wireless communication unit may have a wide portion that is not inserted into the insertion hole and is wider than the insertion portion. Accordingly, the wide portion can be positioned relative to the ceiling on the interior space side.

[0016] In this configuration, the wide section can accommodate an antenna. Therefore, it is possible to provide relatively high-intensity radio waves into an indoor space.

[0017] In this configuration, the second connector can be disposed on the wide portion, and power supplied via the second connector is supplied to the antenna housed in the wide portion through the insertion portion. Accordingly, power can be supplied to the antenna from the second connector disposed on the wide portion via the insertion portion.

[0018] In this configuration, the wireless communication unit may include: an operable portion disposed on the wide portion; and a claw portion disposed on the insertion portion, which releases its engagement with the base unit by operating the operable portion. This facilitates the disassembly of the wireless communication unit.

[0019] In this configuration, the wireless communication unit may have a light-emitting portion that illuminates light toward the ceiling. Accordingly, information can be displayed using the light illuminating the ceiling.

[0020] In this configuration, the base unit may have a protrusion extending into the insertion hole, and the wireless communication unit may have a recess corresponding to the protrusion in the insertion portion. The first connector and the second connector are disposed on the surfaces of the protrusion and the recess facing the insertion direction. Accordingly, the first connector and the second connector can be connected while suppressing mis-insertion.

[0021] In another embodiment of the present invention, the wireless communication unit is configured to be detachable from a base unit mounted on the ceiling, and has a second connector that connects to a first connector of the base unit when mounted thereon. It operates by being powered via the first and second connectors. In this wireless communication unit, the base unit is mounted on the edge of a hole formed in the ceiling, and at least a portion of the wireless communication unit is located inside the hole in the ceiling when mounted on the base unit. This improves heat dissipation.

[0058] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in this specification and the various drawings, components identical to those described in the previously shown figures are labeled with the same symbols, and detailed descriptions are sometimes appropriately omitted.

[0059] Figure 1 and Figure 2 This is a perspective view showing an example of a wireless communication component 100. Figures 3 to 6 This is an exploded perspective view showing an example of the wireless communication component 100. Figure 7 and Figure 8 These are bottom and side views illustrating an example of a wireless communication component 100. Figure 9 This is a block diagram representing an example of wireless communication unit 1.

[0060] In the diagram, X1 is the forward direction, X2 is the backward direction, Y1 is the right direction, and Y2 is the left direction. X1, X2, and Y1 or Y2 are also referred to as the lateral direction. Z1 is the upward direction, and Z2 is the downward direction.

[0061] The wireless communication component 100 includes a wireless communication unit 1 and a base unit 2. The base unit 2 is mounted on the ceiling CL (see reference). Figure 8 The wireless communication unit 1 is configured to be detachable from the base unit 2.

[0062] Wireless communication unit 1 is, for example, a unit that implements wireless local area network (LAN) communication according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. The base unit 2, mounted on the ceiling CL, facilitates the construction and expansion of the communication area.

[0063] The base unit 2 is installed on the edge PH of the hole formed in the ceiling CL. The ceiling CL is a panel wall located in the upper part of the room. Above the ceiling CL is the inner ceiling space AC, and below the ceiling CL is the interior space RM (see reference). Figure 8 ).

[0064] The base unit 2 is formed in an annular shape and has an insertion hole 2a. When the base unit 2 is installed on the edge PH of the hole in the ceiling CL, the insertion hole 2a is located inside the hole in the ceiling CL.

[0065] The base unit 2 includes a pair of arc-shaped bands 21, a pair of box portions 22 and 23 connected to the ends of the bands 21, and a flange portion 24 extending outward.

[0066] The belt portion 21 is a strip-shaped portion that extends in an arc shape when viewed from above, with its width defined by the vertical direction. One end of the belt portion 21 is connected to the housing portion 22, and the other end is connected to the housing portion 23. A pair of belt portions 21 face each other across the insertion hole 2a.

[0067] Box sections 22 and 23 are columnar parts that are formed in an arc shape when viewed from above, with a circular outer surface and a flat inner surface, and extend upwards further than the belt section 21. Box sections 22 and 23 face each other across the insertion hole 2a.

[0068] Box section 22 and box section 23 have different sizes. Hereinafter, the smaller box section 22 will be referred to as "small box section 22" and the larger box section 23 will be referred to as "large box section 23".

[0069] The outer surfaces of the belt section 21, the box section 22, and the box section 23 form a circumferential surface and are inserted into the circular hole of the ceiling CL, abutting against the edge PH of the hole.

[0070] Insertion holes 2a are formed on the inner surfaces of the belt portion 21, the box portion 22, and the box portion 23. The insertion holes 2a have an asymmetrical shape composed of a combination of curved and flat surfaces. Specifically, the insertion holes 2a have a symmetrical shape that rotates one revolution around the vertical direction.

[0071] The flange 24 extends outward from the lower ends of the belt 21, the box 22, and the box 23. Since the flange 24 is larger than the hole in the ceiling CL, it is positioned on the interior space RM side instead of being inserted into the hole in the ceiling CL.

[0072] Although not shown in the diagram, the large enclosure 23 houses communication equipment for wired LAN connection and is connected to a LAN cable laid in the ceiling space AC. However, the communication equipment can also be housed in the smaller enclosure 22.

[0073] Power cables can be connected to the large enclosure 23, but electrical work can be omitted by using Power over Ethernet (PoE) devices that can provide power via LAN cables in the communication equipment housed in the large enclosure 23 and the upper-level communication equipment (e.g., switching hubs).

[0074] A connector 25 is provided on the lower surface of the large housing section 23. The connector 25 is a female connector with an opening formed on the lower surface. The connector 25 is, for example, a Universal Serial Bus (USB) connector (in this example, a USB Type-C connector). The connector 25 may also be a male connector.

[0075] The base unit 2 can be fixed to the ceiling CL by means of screws to fix the flange 24, or by means of adhesive, or by means of rod-shaped members such as bolts protruding outward from the box 22 and box 23.

[0076] The wireless communication unit 1 includes an insertion part 11 that is inserted into an insertion hole 2a in the base unit 2, and a wide part 12 located below the insertion part 11, not inserted into the insertion hole 2a, and wider than the insertion part 11.

[0077] When the wireless communication unit 1 is installed in the base unit 2, at least a portion of it is located inside the hole in the ceiling CL. Specifically, when the wireless communication unit 1 is installed in the base unit 2, the upper half of the insertion part 11 is housed in the inner space AC of the ceiling (see reference). Figure 8 ).

[0078] By mounting the wireless communication unit 1 on the edge PH of the hole in the ceiling CL and placing the upper part of the wireless communication unit 1 in the inner space AC of the ceiling, the heat generated by the wireless communication unit 1 can be discharged to the inner space AC of the ceiling.

[0079] The side of the insertion part 11 includes a pair of curved surfaces 141 and a pair of flat surfaces 142, 143 connected to the ends of the curved surfaces 141. These correspond to a pair of arc-shaped bands 21 of the base unit 2 and a pair of box-shaped sections 22, 23 connected to the ends of the bands 21.

[0080] The planar portions 142 and 143 have different sizes. Hereinafter, the smaller planar portion 142 will be referred to as "small planar portion 142", and the larger planar portion 143 will be referred to as "large planar portion 143".

[0081] The side of the insertion part 11 has an asymmetrical shape formed by the combination of a curved part 141, a flat part 142, and a flat part 143, which corresponds to the insertion hole 2a of the base unit 2. Specifically, the insertion part 11 has a symmetrical shape that rotates one revolution around the insertion direction (vertical direction).

[0082] In other words, the insertion part 11 will not overlap with itself unless it is rotated 360 degrees around the insertion direction. As a result, the rotation angle of the insertion part 11 of the wireless communication unit 1, which can be inserted into the insertion hole 2a of the base unit 2, around the insertion direction is uniquely determined, and misinsertion can be prevented.

[0083] Furthermore, the shapes of the insertion hole 2a of the base unit 2 and the insertion part 11 of the wireless communication unit 1 are not limited to the example shown in the figure. There are no particular limitations as long as the asymmetrical shape can prevent misinsertion.

[0084] Since the wide section 12 is larger than the insertion hole 2a of the base unit 2, it is not inserted into the insertion hole 2a but is disposed on the RM side of the indoor space. Multiple antennas 32 are housed in the wide section 12 (see reference). Figure 7 and Figure 9 Therefore, it can provide relatively high-intensity radio waves to the indoor space RM.

[0085] A connector 15 is provided on the upper surface of the wide portion 12. Specifically, the connector 15 is provided in the area of ​​the upper surface of the wide portion 12 adjacent to the large flat portion 143 of the insertion portion 11.

[0086] Connector 15 is a male connector, protruding upward from the upper surface of the wide portion 12. Connector 15 is, for example, a USB connector (in this example, a USB Type-C connector). Connector 15 can also be a female connector.

[0087] When the wireless communication unit 1 is mounted on the base unit 2, the connector 15 of the wireless communication unit 1 is connected to the connector 25 of the base unit 2. The wireless communication unit 1 performs data transmission via the connector 15 and the connector 25, and operates by being powered via the connector 15 and the connector 25.

[0088] Specifically, the insertion part 11 of the wireless communication unit 1 is inserted into the insertion hole 2a of the base unit 2 from below, and the upper surface of the wide part 12 reaches the lower surface of the base unit 2. During this process, the connector 15 protruding upward from the upper surface of the wide part 12 is inserted into the connector 25 formed on the lower surface of the base unit 2.

[0089] Therefore, the connection direction of connectors 15 and 25 is the same as the insertion direction of the insertion part 11 of wireless communication unit 1 and the insertion hole 2a of base unit 2. Thus, by installing wireless communication unit 1 on base unit 2, connectors 15 and 25 can be connected at the same time.

[0090] A claw 18 for engaging with the base unit 2 is provided on the side of the insertion portion 11 of the wireless communication unit 1. An operable portion 19 that is linked with the claw 18 is provided on the side of the wide portion 12.

[0091] A claw portion 18 is provided on the curved surface 141 of the insertion portion 11 and engages with the belt portion 21 of the base unit 2. The claw portion 18 is exerted outward by a spring (not shown) disposed on the inner side and is displaced according to the operation of the operated portion 19.

[0092] The insertion part 11 of the wireless communication unit 1 is inserted into the insertion hole 2a of the base unit 2. During this process, the claw part 18 is pressed into the inside by the band part 21. After the insertion is completed, the claw part 18 passes over the band part 21 and returns to the outside, thereby engaging the claw part 18 with the band part 21.

[0093] On the other hand, when the operating part 19 is pressed in by a person's finger or the like, the claw part 18 moves inward, thereby releasing the engagement between the claw part 18 and the belt part 21, and the wireless communication unit 1 can be detached from the base unit 2.

[0094] like Figure 9As shown, regarding the wireless communication unit 1, a wireless communication module 31 is housed in the insertion part 11, and a plurality of antennas 32 are housed in the wide part 12. Power supplied via a connector 15 provided on the upper surface of the wide part 12 is supplied to the antennas 32 housed in the wide part 12 through the wireless communication module 31 housed in the insertion part 11.

[0095] Wireless communication unit 1 functions as an access point or repeater (i.e., a repeater) through mode switching.

[0096] In Access Point mode (hereinafter also referred to as AP mode), wireless communication unit 1 provides a connection to the wired LAN to the wireless communication terminal (not shown). Additionally, in AP mode, wireless communication unit 1 functions as a mesh parent device.

[0097] In repeater mode, wireless communication unit 1 enables wireless communication between the relay access point (not shown) and the wireless communication terminal (not shown). Additionally, in repeater mode, wireless communication unit 1 functions as a grid sub-device.

[0098] When the base unit 2 is connected to a wired LAN, the wireless communication unit 1 operates in AP mode; when the base unit 2 is not connected to a wired LAN, the wireless communication unit 1 operates in repeater mode.

[0099] Additionally, a light-emitting unit 33 may be housed in the wide section 12. The light-emitting unit 33 is connected to the wireless communication module 31 and displays information such as power-on status or communication status through light. The light-emitting unit 33 may be configured to emit light toward the ceiling, thereby enabling the display of information such as power-on status or communication status through indirect lighting.

[0100] Figures 10 to 12 These are perspective views and exploded perspective views of a modified wireless communication component 100A. For structures that are repeated in the described embodiment, detailed descriptions are sometimes omitted by using the same numbering.

[0101] The base unit 2A includes an arc-shaped strip 26 surrounding the insertion hole 2a and a straight strip 29. The strip 26 has an engagement hole 26a for engaging with the claw portion 18 of the wireless communication unit 1A.

[0102] Additionally, the base unit 2A has a cuboid protrusion 27 that protrudes from the strip 29 into the insertion hole 2a. A communication device for wired LAN connection is housed in the protrusion 27, and a connection hole 51 for LAN cable connection is provided on the outer surface of the strip 29.

[0103] A connector 28 is provided on the lower surface of the protrusion 27. The connector 28 is a male connector and protrudes downward. The connector 28 is, for example, a USB connector (in this example, a USB Type-C connector). The connector 28 can also be a female connector.

[0104] The side of the insertion portion 11 of the wireless communication unit 1A includes a curved portion 146 and a flat portion 148. These correspond to the arc-shaped strip portion 26 and the straight strip portion 29 of the base unit 2A, respectively.

[0105] Furthermore, the insertion portion 11 of the wireless communication unit 1A has a recess 112 corresponding to the protrusion 27 of the base unit 2A. The recess 112 has openings on the upper surface portion 149 and the flat portion 148, allowing the protrusion 27 of the base unit 2A to be inserted and fitted.

[0106] A connector 118 is provided on the bottom surface of the recess 112. The connector 118 is a female connector and has an opening formed on the bottom surface. The connector 118 is, for example, a USB connector (in this example, a USB Type-C connector). The connector 118 can also be a male connector.

[0107] When the wireless communication unit 1A is installed on the base unit 2A and the protrusion 27 is inserted into the recess 112, the connector 118 of the wireless communication unit 1A is connected to the connector 28 of the base unit 2A.

[0108] Specifically, the insertion part 11 of the wireless communication unit 1A is inserted into the insertion hole 2a of the base unit 2A from below, and the bottom surface of the recess 112 reaches the lower surface of the protrusion 27. During this process, the connector 28 protruding downward from the lower surface of the protrusion 27 is inserted into the connector 118 formed on the bottom surface of the recess 112.

[0109] In the wireless communication unit 1A, the connector 118 is disposed in the recess 112 of the insertion portion 11 instead of the wide portion 12, thereby enabling the wide portion 12 to be made thinner.
