Detailed implementation manners
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Figure 1 A schematic structural diagram of an Internet of Things module 1 provided by an embodiment of the present application, wherein part of the first housing 10 is omitted. As Figure 1As shown in the figure, the Internet of Things module 1 includes a first housing 10 and a first main board 11 disposed in the first housing 10. Specifically, the first housing 10 has a first surface 10a and a second surface 10b that are oppositely disposed. Among them, at least one first connector 12 and at least one second connector 13 are provided on the second surface 10b, and the first connector 12 can be selectively connected to the first main board 11. That is to say, it can be selected whether to connect the first connector 12 to the first main board 11 according to actual needs. When the first connector 12 is connected to the first main board 11, the first connector 12 is used for the transmission of radio frequency signals between the first connector 12 and a wireless access point device ( Figure 1 not shown in the figure). The second connector 13 is connected to the first main board 11, and the second connector 13 is used for the transmission of control signals between the second connector 13 and the wireless access point device.
[0036] In this solution, on the one hand, the Internet of Things module 1 can be plugged into the wireless access point device through the first connector 12 and the second connector 13, and the assembly between the Internet of Things module 1 and the wireless access point device 2 is more convenient and fast; on the other hand, the Internet of Things module 1 can utilize the radio frequency circuit and antenna of the wireless access point device connected thereto, that is, utilize the wireless network of the wireless access point device. Compared with the situation of additionally setting up an Internet of Things base station in the related art, it is more cost-saving and can also avoid the interference between the Internet of Things base station and the wireless access point device.
[0037] In some embodiments, the Internet of Things module 1 does not have an antenna itself. The first connector 12 is connected to the first main board 11, and the Internet of Things module 1 can be connected to the antenna of the wireless access point device through the first connector 12, so as to utilize the antenna of the wireless access point device.
[0038] As Figure 2 shown in the figure, in other embodiments, the Internet of Things module 1 includes a first antenna 14. The first antenna 14 is connected to the first main board 11, and the first connector 12 is independent of the first main board 11. That is to say, when the Internet of Things module 1 has an antenna itself, the first connector 12 is not connected to the first main board 11. Exemplarily, the first antenna 14 can be an Figure 2 external antenna shown in the figure. The first housing is provided with an antenna port (for example: a radio frequency connector). The outer end of the antenna port is connected to an external antenna or the external antenna is remotely arranged through a feeder, and the inner end of the antenna port is connected to the first main board 11 through a radio frequency feeder. The first antenna 14 can also be an Figure 3 internal antenna shown in the figure.
[0039] In some embodiments, the second connector also serves as an electrical connector and is used to electrically connect to a wireless access point device. In this way, the structural settings of the Internet of Things module 1 and the wireless access point device 2 can be simplified. Of course, the Internet of Things module 1 and the wireless access point device 2 can also be electrically connected through a separate pair of connectors, or the Internet of Things module 1 can also adopt other power supply methods.
[0040] Figure 4 FIG. 4 is a schematic structural diagram of a wireless access point device 2 provided in this embodiment. Figure 5 is Figure 4 FIG. 5 is a schematic structural diagram of the wireless access point device 2 shown in FIG. 4 with a part of the second housing 20 omitted. As Figure 4 and Figure 5 shown, a wireless access point device 2 provided in this embodiment includes a second housing 20 and a second main board 21 disposed in the second housing 20. The second housing 20 has an installation opening 201 for installing the above-mentioned Internet of Things module 1. Specifically, the second main board 21 is provided with a third connector 22 and a fourth connector 23. The third connector 22 is used to plug into the first connector 12 of the Internet of Things module 1 to realize the transmission of radio frequency signals between the Internet of Things module 1 and the second main board 21 when the first connector 12 is connected to the first main board 11; the fourth connector 23 is a control signal connector and is used to plug into the second connector 13 to realize the transmission of control signals between the wireless access point device 2 and the Internet of Things module 1.
[0041] In this solution, on the one hand, the wireless access point device 2 can be plugged into the Internet of Things module 1, making the assembly between the Internet of Things module 1 and the wireless access point device 2 more convenient and fast; on the other hand, the Internet of Things module 1 can utilize the radio frequency circuit and antenna of the wireless access point device 2, that is, the Internet of Things module 1 utilizes the wireless network of the wireless access point device 2. Compared with the situation of additionally setting up an Internet of Things base station in the related art, it is more cost-saving and can also avoid the interference between the Internet of Things base station and the wireless access point device 2.
[0042] In some embodiments, the wireless access point device 2 includes a second antenna 24. The second main board 21 is provided with a radio frequency signal generating unit, and the second main board 21 includes a radio frequency circuit. Both the radio frequency signal generating unit and the second antenna 24 are connected to the radio frequency circuit. A first radio frequency switch is provided between the radio frequency signal generating unit and the radio frequency circuit, and a second radio frequency switch is provided between the third connector 22 and the radio frequency circuit. The first radio frequency switch can be opened and closed under the control of a corresponding control signal, and the second radio frequency switch can also be opened and closed under the control of a corresponding control signal, so that the radio frequency signal generating unit or the third connector 22 can be selectively connected to the radio frequency circuit of the wireless access point device 2, that is, the Internet of Things module 1 or the wireless access point device 2 can be selectively made to use the second antenna 24. Exemplarily, the wireless access point device 2 includes a control unit, and both the first radio frequency switch and the second radio frequency switch are connected to the control unit and can be opened and closed under the control of a control signal sent by the control unit.
[0043] It should be understood that when the frequency band of the signal transmitted by the radio frequency signal generating unit of the wireless access point device 2 is the same as the frequency band of the signal transmitted by the radio frequency signal generating unit of the Internet of Things module 1, the radio frequency signal generating unit and the third connector 22 of the wireless access point device 2 are connected to the radio frequency circuit of the wireless access point device 2 in a time-sharing manner. When the frequency band of the signal transmitted by the radio frequency signal generating unit of the wireless access point device 2 is different from the frequency band of the signal transmitted by the radio frequency signal generating unit of the Internet of Things module 1, the radio frequency signal generating unit and the third connector 22 of the wireless access point device 2 can be simultaneously connected to the radio frequency circuit of the wireless access point device 2.
[0044] Such as Figure 5 and Figure 6 As shown, in some possible implementation manners, the second antenna 24 is an external antenna, and the second housing 20 is provided with a plurality of antenna ports 25. The radio frequency circuit includes a one-to-many power splitter 211, and each output port of the one-to-many power splitter 211 is connected to an antenna port 25. Each antenna port 25 is connected to a second antenna 24. As shown in Figure 5 the second antenna 24 can be directly connected to the antenna port 25; as shown in Figure 6 the second antenna 24 can also be connected to the antenna port 25 through a feeder 100, thereby expanding the deployment range of the wireless network. Exemplarily, as shown in Figure 6 two third connectors 22 are provided on the second main board, and each third connector 22 is connected to four antenna ports 25 through a one-to-four power splitter.
[0045] It is not difficult to understand that the radio frequency circuit may further include a power amplifier, a filter, etc. provided upstream or downstream of the power splitter.
[0046] In some other embodiments, the second antenna 24 is an internal antenna.
[0047] In some embodiments, the fourth connector also serves as an electrical connector and is used to electrically connect to the Internet of Things module. In this way, the structural arrangement of the Internet of Things module 1 and the wireless access point device 2 can be simplified.
[0048] Figure 7 FIG. 4 is an exploded view of a wireless access point device provided in this embodiment, in which a part of the first housing is omitted. Figure 8 FIG. 5 is an exploded view of a wireless access point device provided in this embodiment, in which a part of the second housing is omitted. As Figure 7 and Figure 8 shown, a wireless access point device provided in this embodiment includes the above-mentioned Internet of Things module 1 and the above-mentioned wireless access point device 2. The Internet of Things module 1 is inserted into the installation port 201 of the wireless access point device 2. The second surface 10b of the Internet of Things module 1 is located in the second housing 20. The extending directions of any of the first connector 12, the second connector 13, the third connector 22, and the fourth connector 23 are all parallel to the insertion and extraction direction of the Internet of Things module 1. That is to say, the insertion and extraction direction of the first connector 12 relative to the third connector 22 and the insertion and extraction direction of the second connector 13 relative to the fourth connector 23 are both parallel to the insertion and extraction direction of the Internet of Things module 1. In this solution, on the one hand, the wireless access point device 2 can be plugged into the Internet of Things module 1, making the assembly between the Internet of Things module 1 and the wireless access point device 2 more convenient and fast; on the other hand, the Internet of Things module 1 can utilize the radio frequency circuit and antenna of the wireless access point device 2, that is, the Internet of Things module 1 utilizes the wireless network of the wireless access point device 2. Compared with the situation of additionally setting up an Internet of Things base station in the related art, it is more cost-saving and can also avoid the interference between the Internet of Things base station and the wireless access point device 2.
[0049] In addition, the structure of the device is more concise, and the insertion and extraction direction of the first connector 12 relative to the third connector 22 and the insertion and extraction direction of the second connector 13 relative to the fourth connector 23 are both parallel to the insertion and extraction direction of the Internet of Things module 1, making the installation operation of the Internet of Things module 1 more convenient.
[0050] The first surface 10a of the first housing 10 may be provided with a connection hole, and the outer side of the installation port 201 on the second housing 20 may be provided with a threaded hole. The screw 15 passes through the connection hole on the first surface 10a and is connected to the threaded hole on the outer side of the installation port 201 of the second housing 20 to fix the Internet of Things module 1 to the wireless access point device 2. Exemplarily, the head of the screw 15 may protrude from the first surface 10a so that the operator can hold it when taking and placing the Internet of Things module 1, making it more convenient to operate.
[0051] It should be understood that there is at least one first connector 12, that is to say, the first connector 12 can be one or more. Similarly, the third connector 22 can also be one or more. The third connector 22 corresponds to the first connector 12 one by one. When there are multiple first connectors 12, the multiple first connectors 12 are respectively connected to a group of second antennas 24 through the corresponding third connectors 22. As Figure 9 shown, the Internet of Things module 1 is provided with two first connectors 12, and each of the two first connectors 12 is connected to four second antennas 24 through a third connector 22. As Figure 10 shown, the Internet of Things module 1 is provided with two first connectors 12, and the two first connectors 12 are respectively connected to a built-in second antenna 24 through the third connector 22 and the second main board.
[0052] The first surface 10a of the Internet of Things module 1 is coplanar with the surface of the wireless access point device 2, so that the appearance of the wireless access point device 2 is more regular, thereby reducing the space occupied by the wireless access point device 2 and facilitating the avoidance of the separation of the first connector 12 and the third connector 22 and the separation of the second connector 13 and the fourth connector 23 caused by misoperation. In addition, in this solution, the appearance of the wireless access point device 2 has stronger integrity and is more beautiful.
[0053] Specifically, both between the first connector 12 and the third connector 22 and between the second connector 13 and the fourth connector 23 are pluggable connections, and the Internet of Things module 1 can be detachably connected to the wireless access point device 2 to facilitate the later maintenance of the Internet of Things module 1. Exemplarily, the Internet of Things module 1 and the wireless access point device 2 can be snap-connected or screwed.
[0054] It can be seen that the wireless access point device 2 provided in this embodiment can be compatible with various antenna deployment requirements of the Internet of Things module 1, such as: external antennas, or other internal antennas such as PFC antennas, rod antennas, and FPC antennas pasted on the main board of the Internet of Things module 1.
[0055] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
