Description
Technical Field
[0001] The utility model relates to the field of electric clothes drying machines, and in particular to a clothes drying machine WiFi module adapter board, an upright WiFi module and an integrated PCB board, which are used for welding on a main control board of the clothes drying machine and connecting and communicating with a wireless network in an environment. Background Art
[0002] As smart home technology becomes increasingly popular in people's daily lives, wireless communication technologies are also widely used. Among them, WiFi communication technology is favored by developers and users due to its wide coverage, fast transmission speed, and low cost.
[0003] There are many established WiFi chip design companies on the market, each with its own unique product offerings. As chip users, home appliance companies typically don't directly configure the various WiFi chip functions, but instead purchase and use established configurations from various manufacturers. The current mainstream approach is to combine a WiFi chip with an onboard antenna, power supply, and metal shielding to create a single WiFi module.
[0004] like Figure 1 As shown, in the prior art of clothes drying machines, most manufacturers typically use stamp holes for the WiFi module's solder pads, allowing the WiFi module to be directly soldered to the PCB. Referring to the specifications and drawings of invention patent No. CN113668202B and utility model patent No. CN211826964U, it can be seen that the WiFi module is placed flat and soldered to the PCB.
[0005] However, this method of welding and using the WiFi module places high demands on the layout and wiring of the PCB board:
[0006] First of all, in order to reduce signal interference on the onboard antenna of the WiFi module and provide a better use environment, it is generally necessary to hollow out part of the PCB board below and around it. The premise of hollowing out the PCB board is that there is sufficient idle space on the PCB board.
[0007] In addition, the WiFi module needs to be kept away from various interference sources on the PCB board, such as switching power supplies, RF antennas, lighting drivers and other modules. Such high spatial layout and wiring requirements make it difficult to integrate more modules on the PCB board, and the size of the PCB board is also difficult to miniaturize. Utility Model Content
[0008] Given that the WiFi module used in existing clothes drying machines is directly soldered on the PCB board, it has high requirements for the layout and wiring of the PCB board, which makes it difficult to integrate and miniaturize the PCB board.

[0049] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0051] like Figure 1 The figure shows the structure of an integrated PCB 400 for a clothes drying machine in the prior art. A WiFi module 402 is placed flat and soldered to PCB 401. Because PCB 401 also contains other electronic components, which are typically higher than the flat WiFi module 402, the signal from WiFi module 402 is subject to some interference. Therefore, a window 404 is formed by hollowing out a portion of PCB 401 below and around WiFi module 402. The onboard antenna 403 of WiFi module 402 is exposed through window 404.
[0052] As described in the “Background Technology” section above, this welding and usage method places high demands on the layout and wiring of the integrated PCB board 400 , making it difficult to integrate and miniaturize the integrated PCB board 400 as a whole.
[0053] like Figure 2The figure shows the integrated PCB board 300 for the clothes drying machine provided in this embodiment, which includes a PCB board 301 and a clothes drying machine upright WiFi module 200. The clothes drying machine upright WiFi module 200 is not soldered flat on the PCB board 301, but is directly soldered on the PCB board 301 with the onboard antenna 14 facing upward, forming an upright installation form.
[0054] Specifically, let's look at the structure of the clothes drying machine upright WiFi module 200. Figures 3 to 5 As shown, the clothes drying machine upright WiFi module 200 includes a WiFi module 10 and a clothes drying machine WiFi module adapter board 100. The WiFi module 10 includes an integrated chip carrier 11 and a metal shield 12. The integrated chip carrier 11 integrates a WiFi chip (not shown) and an onboard antenna 14. The metal shield 12 is welded to the integrated chip carrier 11 to shield the WiFi chip from the outside world and isolate it from electromagnetic interference. The onboard antenna 14 is exposed through the metal shield 12 to receive and transmit WiFi signals.
[0055] like Figure 3 As shown, the clothes drying machine WiFi module adapter board 100 includes a patch portion 110 and a solder pad portion 120. In this embodiment, the patch portion 110 is generally rectangular and is used for soldering and fixing the WiFi module 10. It should be understood that the patch portion 110 has at least two oppositely disposed side portions, one of which is a first side portion 111 and the opposite side is a second side portion 112.
[0056] The pad portion 120 is integrally formed with the patch portion 110 and extends outward from the edge of the first side portion 111 of the patch portion 110 for direct soldering to the PCB 301. The pad portion 120 includes four first network pads 1p: a first power pad 1p1, a first ground pad 1p2, a first RX pad 1p3, and a first TX pad 1p4. The four first network pads 1p are arranged in sequence along the edge of the first side portion 111.
[0057] like Figure 4 and Figure 5 As shown, the integrated chip carrier 11 is soldered and fixed to the patch portion 110. The onboard antenna 14 is oriented opposite to the extension direction of the pad portion 120 and extends beyond the edge of the second side portion 112 opposite the first side portion 111 of the patch portion 110 to prevent the clothes drying machine WiFi module adapter board 100 from interfering with the WiFi signal transmission and reception of the onboard antenna 14.
[0058] like Figure 6As shown in the circuit diagram of the WiFi chip, in WiFi chip U1, VDD is the power port, GND is the ground port, IO6 is the reserved RX port, and IO7 is the reserved TX port. When WiFi module 10 is soldered to clothes drying machine WiFi module adapter board 100, the WiFi chip's power port, ground port, reserved RX port, and reserved TX port are electrically connected to the first power pad 1p1, first ground pad 1p2, first RX pad 1p3, and first TX pad 1p4 of pad section 120, respectively. The reserved RX port and reserved TX port are used to connect to the serial communication port of the microcontroller (not shown) on PCB board 301 for data communication.
[0059] like Figure 3 As shown, preferably, the pad portion 120 further includes an anti-reverse connection plug 121 , and the anti-reverse connection plug 121 is arranged beside the first network pad 1 p .
[0060] like Figures 7 to 10 As shown, four second network pads 2p are provided on the PCB board 301, namely, a second power pad 2p1, a second ground pad 2p2, a second RX pad 2p3, and a second TX pad 2p4, which correspond one-to-one with the four first network pads 1p. The clothes drying machine upright WiFi module 200 is directly soldered to the PCB board 301 with the onboard antenna 14 facing upward. The four first network pads 1p of the clothes drying machine WiFi module adapter board 100 are electrically connected one-to-one with the four second network pads 2p, namely, the first power pad 1p1 is electrically connected to the second power pad 2p1, the first ground pad 1p2 is electrically connected to the second ground pad 2p2, the first RX pad 1p3 is electrically connected to the second RX pad 2p3, and the first TX pad 1p4 is electrically connected to the second TX pad 2p4.
[0061] Preferably, in this embodiment, the clothes drying machine WiFi module adapter board 100 is directly soldered on the PCB board 301 using a gold finger connection method. Figures 7 to 10 As shown, the PCB 301 is provided with a socket slot 302 that matches the shape of the pad portion 120. The pad portion 120 of the clothes drying machine WiFi module adapter board 100 is also known as a "gold finger plug," and the socket slot 302 is also known as a "gold finger slot." Four second network pads 2p are located adjacent to the socket slot 302. The pad portion 120 is inserted into the socket slot 302, using solder to establish a one-to-one electrical connection between the four first network pads 1p and the four second network pads 2p.
[0062] Furthermore, the socket slot 302 is opened at the edge of the PCB board 301, and the clothes drying machine upright WiFi module 200 is directly inserted and soldered to the edge of the PCB board 301 with the metal shielding cover 12 facing outward, so as to further reduce the interference of other components on the PCB board 301 to the WiFi module 10.
[0063] like Figure 11 The figure shows the clothes drying machine main body housing 500 provided in this embodiment. An opening 501 is provided on the side of the clothes drying machine main body housing 500, and the clothes drying machine integrated PCB board 300 is disposed inside the main body housing 500. A QR code 13 is printed on the outer surface of the metal shield 12, and the QR code 13 is exposed through the opening 501. This allows the user to directly obtain information from the WiFi module 10 by scanning the QR code 13 through the opening 501 without disassembling the clothes drying machine main body housing 500.
[0064] like Figures 7 to 10 As shown, PCB 301 is provided with an anti-reverse connection socket 303 corresponding to anti-reverse connection plug 121. When the clothes drying machine WiFi module adapter board 100 is directly plugged and soldered onto PCB 301, anti-reverse connection plug 121 is inserted and soldered into anti-reverse connection socket 303. The combination of anti-reverse connection plug 121 and anti-reverse connection socket 303 increases the strength of the plug-in and prevents the clothes drying machine WiFi module adapter board 100 from being inserted in the reverse direction, eliminating the need for additional connector terminals.
[0065] Combine Figure 6 As shown in the circuit diagram of the WiFi chip, in this embodiment, the WiFi chip U1 is powered by a 3.3V DC power supply, and its power port VDD is connected to the 3.3V DC power supply. A power supply (not shown) is provided on the PCB board 301. The power supply provides 3.3V DC power and is electrically connected to the second power pad 2p1. When the second power pad 2p1 is electrically connected to the first power pad 1p1, power can be supplied to the WiFi chip.
[0066] The power port VDD of the WiFi chip U1 is grounded via a first decoupling capacitor C1 and a second decoupling capacitor C2 connected in parallel. The first and second decoupling capacitors connected in parallel are also disposed on the PCB board 301 (not shown in the figure), and are located near the second network pad 2p.
[0067] Thus, one end of the first and second decoupling capacitors, connected in parallel, can establish an electrical connection to the second power pad 2p1 via a relatively short path, and then establish an electrical connection to the power port of the WiFi chip via the electrical connection between the second power pad 2p1 and the first power pad 1p1. The other ends of the first and second decoupling capacitors, connected in parallel, are grounded, possibly via a ground terminal on PCB board 301.
[0068] like Figure 6 As shown, in this embodiment, the first decoupling capacitor C1 is 22uF, and the second decoupling capacitor C2 is 100nF.
[0069] The present invention achieves the following three technical effects by soldering a WiFi module to a clothes drying machine WiFi module adapter board 100, and then directly soldering the clothes drying machine upright WiFi module to a PCB board in an upright position with the onboard antenna facing upwards through the clothes drying machine WiFi module adapter board 100:
[0070] First, it overcomes the problem of hollowing out a window on the PCB board in the prior art, and the upright WiFi module itself occupies less PCB board area than the flat type, effectively saving PCB board space, thereby integrating more components on the PCB board with limited space, and further improving the integration and miniaturization of the PCB board.
[0071] Second, the upright WiFi module has an onboard antenna that is positioned higher than most SMD components on the PCB, which reduces interference when the WiFi module transmits and receives signals, eliminating the need to consider other technical means to reduce signal interference.
[0072] Third, the installation method of the clothes drying machine WiFi module adapter board is directly soldered on the PCB board, without the use of additional connection terminals. It can not only effectively control material costs, but also adjust the pad size according to actual conditions, and then adjust the welding area between the adapter board and the PCB board, making the application scenarios more extensive.
[0073] Furthermore, under this installation method, the clothes drying machine WiFi module adapter board can be soldered on the PCB through the wave soldering process, and there is no need to arrange additional manual insertion process, and there is no need to increase additional labor costs.
[0074] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.
[0075] The above describes the clothes drying machine WiFi module adapter board, upright WiFi module, and integrated PCB board provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to facilitate understanding of the present invention and its core concepts.
