Description

Technical Field

[0001] This utility model relates to a wireless transmission module, and more particularly to a wireless transmission module used in wireless communication or wireless charging. Background Technology

[0002] With the development of technology, many electronic devices today (such as tablets or smartphones) have wireless charging capabilities. Users can place the electronic device on a wireless charging transmitter, allowing the wireless charging receiver in the device to generate current using electromagnetic induction or electromagnetic resonance to charge the battery. Due to the convenience of wireless charging, electronic devices with wireless charging modules are gradually becoming more popular.

[0003] Generally, wireless charging modules include a magnetic substrate that carries a coil. When the coil is energized and operates in a wireless charging mode or a wireless communication mode, the magnetic substrate can concentrate the magnetic lines of force emitted by the coil to achieve better performance. However, the structure of existing wireless charging (or communication) modules and the winding method of the coil cannot meet the various requirements of wireless transmission modules, such as the need for better charging and communication performance and a more miniaturized size.

[0004] Therefore, how to design a wireless transmission module that can meet the various needs of users is a topic worthy of discussion and solution today. Utility Model Content

[0014] According to some embodiments of the present invention, a first side plate has a receiving groove configured to receive a coil assembly and a first base. The first side plate also has a first layer and a second layer. The first layer is directly connected to the second layer. The receiving groove is formed in the first layer. The shape of the receiving groove corresponds to the shape of the first base. A first electrical contact and a second electrical contact are located on the second layer. The receiving groove has a first receiving portion and a second receiving portion. The first receiving portion communicates with the second receiving portion.

Based on this structural design, damaged coil assemblies can be easily replaced, or coil assemblies of the same size but different functions can be replaced. Therefore, the same second base can be used, thereby reducing overall production costs. Attached Figure Description

[0104] The following discloses many different implementations or examples to achieve different features of the provided objective. Specific embodiments of components and their arrangements are described below to illustrate the present invention. Of course, these embodiments are merely illustrative and should not be construed as limiting the scope of the present invention. For example, the specification mentions that a first feature is formed on a second feature. This may include embodiments where the first and second feature are in direct contact, or embodiments where there are other features between the first and second feature; in other words, the first and second feature are not in direct contact.

[0105] Furthermore, repeated reference numerals or designations may be used in different embodiments. These repetitions are merely for the purpose of clearly and simply describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed. Additionally, the formation, connection, and / or coupling to another feature component in the present invention may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed to be inserted into the aforementioned feature component, such that the aforementioned feature components may not be in direct contact. Furthermore, spatially related terms may be used, such as “vertical,” “above,” “up,” “below,” “bottom,” and similar terms (e.g., “downward,” “upward,” etc.). These spatially related terms are intended to cover different orientations of the device including the feature in order to facilitate the description of the relationship between one component(s) or feature(s) and another component(s) or feature(s) in the illustrations.

[0106] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, shall be interpreted as having a meaning consistent with the relevant art and the background or context of this invention, and shall not be interpreted in an idealized or overly formal manner, unless otherwise specifically defined herein.

[0107] Furthermore, the use of ordinal numbers such as "first" and "second" in the specification and claims to modify the components of the claims does not imply or represent any prior ordinal number of the claimed component, nor does it represent the order of one claimed component with another claimed component, or the order of manufacturing methods. The use of these ordinal numbers is only to enable a claimed component with a certain name to be clearly distinguished from another claimed component with the same name.

[0108] Furthermore, in some embodiments of this utility model, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or to two structures not in direct contact, wherein another structure is disposed between the two structures. Moreover, these terms regarding joining and connecting may also include cases where both structures are movable or both structures are fixed.

[0109] Please refer to Figure 1 as well as Figure 2 , Figure 1 This is a perspective view of a wireless transmission module 10 according to an embodiment of the present invention, and Figure 2 This is a perspective view of a wireless transmission module 10 according to an embodiment of the present invention from another angle. Figure 1 As shown, the wireless transmission module 10 is a wireless transmission module that can be used to transmit energy or signals. In this embodiment, the wireless transmission module 10 may include a coil assembly 12, a first bonding assembly 13, a sensing base 15, a second bonding assembly 16, and a substrate 18.

[0110] In this embodiment, the coil assembly 12, the first bonding assembly 13, the sensing base 15, the second bonding assembly 16, and the substrate 18 are arranged sequentially and stacked along the extension direction of a winding shaft RX of the coil assembly 12.

[0111] Specifically, the coil assembly 12 is fixedly disposed on the sensing base 15 by the first bonding assembly 13, and the sensing base 15 is fixedly disposed on the substrate 18 by the second bonding assembly 16. In this embodiment, the coil assembly 12 may be a wound coil, the sensing base 15 may be a magnetic body, the first bonding assembly 13 and the second bonding assembly 16 may be double-sided adhesive or single-sided adhesive, and the substrate 18 may be a printed circuit board, but is not limited thereto.

[0112] like Figure 1 and Figure 2As shown, the substrate 18 has a first surface SF1 and a second surface SF2, and the coil assembly 12 and the sensing base 15 are disposed on the first surface SF1. Furthermore, the wireless transmission module 10 may also include multiple electronic components 20 and two electrical contacts 22 disposed on the second surface SF2. The electronic components 20 are, for example, capacitors, resistors, transistors, integrated circuit chips, etc.

[0113] like Figure 1 and Figure 2 As shown, the coil assembly 12 has a first lead WR1 and a second lead WR2, which are respectively connected to two electrical contacts 22. It is worth noting that the first lead WR1 and the second lead WR2 are stretched from the first surface SF1 to the second surface SF2, and an adhesive gel can be provided at the junction of the first surface SF1 and the second surface SF2 to fix the first lead WR1 and the second lead WR2.

[0114] With this configuration, since all electronic components 20 are located on the second surface SF2, there is no need to perform surface mount technology (SMT) processes on both surfaces, which can reduce the SMT process time by half. It also makes it easier for operators to install the coil assembly 12 on the first surface SF1, increasing the convenience of assembly.

[0115] Please refer to the following: Figures 3 to 5 . Figure 3 This is a perspective view of a wireless transmission module 100 according to an embodiment of the present invention. Figure 4 This is a bottom view of a wireless transmission module 100 according to an embodiment of the present invention, and Figure 5 According to an embodiment of the present invention, the wireless transmission module 100 is along... Figure 3 A cross-sectional view of the middle segment AA. In this embodiment, the wireless transmission module 100 may include a coil assembly 102 and a first base 106, wherein the coil assembly 102 defines a winding axis RX, the first base 106 corresponds to the coil assembly 102, and the coil assembly 102 and the first base 106 are arranged along the winding axis RX.

[0116] Furthermore, the wireless transmission module 100 may also include a second base 108 configured to carry the coil assembly 102 and the first base 106. The second base 108 has a first side plate 1081 and a second side plate 1082, which are opposite to each other. For example, the first side plate 1081 and the second side plate 1082 are located on opposite sides of the second base 108.

[0117] The coil assembly 102 and the first base 106 are disposed on the first side plate 1081. Specifically, the wireless transmission module 100 may also include a first bonding component 104, a second bonding component 110, and a protective component 111. The coil assembly 102 is fixed to the first base 106 by the first bonding component 104 and the protective component 111, and the first base 106 is fixed to the first side plate 1081 of the second base 108 by the second bonding component 110.

[0118] In this embodiment, the first base 106 is configured to alter the electromagnetic field distribution near the coil assembly 102. The first base 106 may be a magnetic material, such as ferrite, but is not limited thereto. For example, in other embodiments, the first base 106 may also comprise a nanocrystalline material. The first base 106 may have a permeability corresponding to the coil assembly 102, thereby concentrating the electromagnetic waves emitted by the coil assembly 102.

[0119] The first bonding component 104, the second bonding component 110, and the protective component 111 may be double-sided or single-sided adhesive tape for bonding to one or two adjacent components. In some embodiments, the first bonding component 104, the second bonding component 110, or the protective component 111 may be made of polyethylene terephthalate (PET), but is not limited thereto. For example, the first bonding component 104, the second bonding component 110, and the protective component 111 may also be made of polypropylene (PP).

[0120] like Figure 5 As shown, the protective component 111 corresponds to the second joining component 110. For example, the protective component 111 and the second joining component 110 may have the same size, and the first base 106 is disposed between the second joining component 110 and the protective component 111, such that the second joining component 110 and the protective component 111 together cover and protect the first base 106.

[0121] For example, such as Figure 3 As shown, when viewed along the winding axis RX, the protective component 111 completely shields the first base 106, but is not limited thereto. In other embodiments, the protective component 111 may also be omitted.

[0122] In this embodiment, the coil assembly 102 can serve as a charging coil for wireless charging by an external charging device. For example, the coil assembly 102 can serve as a resonant charging coil based on the Alliance for Wireless Power (A4WP) standard, but is not limited thereto.

[0123] Additionally, the coil assembly 102 can be based on Wireless Power Consortium (WPC) standards, such as the Qi standard, to function as an inductive charging coil. Therefore, this embodiment allows the coil assembly 102 to simultaneously support different charging methods, increasing its applicability. For example, inductive operation can be used at close range (e.g., less than 1 cm), while resonant operation can be used at longer distances.

[0124] In this embodiment, the coil assembly 102 can also serve as a communication coil, for example, operating in Near Field Communication (NFC) mode to communicate with external electronic devices.

[0125] Similar to the foregoing embodiments, the wireless transmission module 100 also includes a plurality of electronic components disposed on the second side panel 1082. These electronic components may include, but are not limited to, resistors 151, inductors 152, capacitors 153, integrated circuit chips 154, transistors 155, or combinations thereof.

[0126] It is also worth noting that these electronic components do not include any coils for wireless transmission. That is, the wireless transmission module 100 has only a single coil assembly 102 disposed on the first side plate 1081, while no coils for wireless transmission are disposed on the second side plate 1082.

[0127] like Figure 3 and Figure 5 As shown, the second base 108 also has a first electrical contact EC1 and a second electrical contact EC2, which are disposed on the first side plate 1081 and configured to be electrically connected to the coil assembly 102.

[0128] like Figure 3 As shown, the coil assembly 102 has a winding body 1020, a first lead 1021 and a second lead 1022. The first lead 1021 and the second lead 1022 extend from the winding body 1020 and are configured to be connected to the first electrical contact EC1 and the second electrical contact EC2, respectively.

[0129] It is worth noting that the coil assembly 102 can be a patterned coil with a thin structure. Specifically, such as... Figure 5 As shown, the thickness TH1 of the winding of the coil assembly 102 on the winding axis RX (Z axis) is less than 1 mm, for example, 0.38 mm, but is not limited thereto.

[0130] Furthermore, such as Figure 3As shown, the width TW1 of the first lead 1021 or the second lead 1022 is greater than 1 mm, for example, 1.5 mm or 2 mm, but is not limited thereto. Based on this configuration, the overall thickness of the wireless transmission module 100 can be further reduced, achieving miniaturization.

[0131] Next, in this embodiment, as Figure 4 As shown, the second base 108 may be a printed circuit board, which may contain multiple traces, partially disposed between the first side plate 1081 and the second side plate 1082.

[0132] In this embodiment, the second base 108 has a multi-layer structure, for example, such as Figure 5 As shown, the first side plate 1081 is the first layer, the second side plate 1082 is, for example, the fourth layer, and the second base 108 also includes a central layer plate 1084, which is disposed between the first side plate 1081 and the second side plate 1082.

[0133] The central layer 1084 is, for example, the third and fourth layers, and a portion of these traces are located within the central layer 1084. These traces can be distributed across the third and fourth layers or two other layers.

[0134] These traces are configured to electrically connect to these electronic components. For example, such as Figure 4 As shown, one of the traces, TR11, connects the integrated circuit chip 154 ​​and the resistor 151, while the other trace, TR12, connects the integrated circuit chip 154 ​​and the capacitor 153.

[0135] It is worth noting that, such as Figure 4 As shown, when viewed along the winding axis RX (Z-axis), a portion of these traces (e.g., trace TR12) overlaps a portion of the coil assembly 102. Since the first base 106 is positioned between the coil assembly 102 and these traces, the traces and the coil assembly 102 do not interfere with each other and can operate normally. That is, the first base 106 has a protective and isolating function.

[0136] Please continue to refer to this. Figure 4 In this embodiment, the second base 108 further includes two power input contacts PC1 disposed on the second side panel 1082. The two power input contacts PC1 are configured to be electrically connected to one of the electronic components via two of these traces. For example, the two power input contacts PC1 are electrically connected to the inductor 152 via two traces TR13.

[0137] Additionally, the second base 108 may also include a plurality of detection contacts TP1 disposed on the second side plate 1082. These detection contacts TP1 are configured to be electrically connected to at least one of these electronic components. The user can use the detection contacts TP1 to detect whether these electronic components are operating normally.

[0138] For example, the test contact TP1 can be electrically connected to the integrated circuit chip 154 ​​via the trace TR14, so that the user can use the test contact TP1 to detect whether the integrated circuit chip 154 ​​is operating normally.

[0139] Furthermore, such as Figure 4 and Figure 5 As shown, the second base 108 also includes a first through hole VA1 and a second through hole VA2, and the first through hole VA1 and the second through hole VA2 penetrate the central layer plate 1084.

[0140] These detection contacts TP1 may include a first detection contact TP11 and a second detection contact TP12, a first through hole VA1 is configured to connect to the first electrical contact EC1 and the first detection contact TP11, and a second through hole VA2 is configured to connect to the second electrical contact EC2 and the second detection contact TP12.

[0141] For example, such as Figure 5 As shown, the second through-hole VA2 connects to the second electrical contact EC2, and the second through-hole VA2 is then connected to the second detection contact TP12 via the trace TR15. Therefore, the user can detect the coil assembly 102 through the first detection contact TP11 and the second detection contact TP12.

[0142] Please refer to the following: Figure 6 as well as Figure 7 . Figure 6 This is an exploded view of a wireless transmission module 100A according to another embodiment of the present invention, and Figure 7 According to another embodiment of the present invention, the wireless transmission module 100A is along... Figure 6 A cross-sectional view of the middle segment BB. In this embodiment, the coil assembly 102, the first coupling assembly 104, and the first base 106 are arranged sequentially along the winding axis RX.

[0143] It is worth noting that the size of the first base 106 is larger than the size of the coil assembly 102. That is, when viewed along the winding axis RX, the first lead 1021 and the second lead 1022 completely overlap the first base 106, and the first base 106 is configured to support the first lead 1021 and the second lead 1022.

[0144] The first joining component 104 corresponds to the shape of the coil assembly 102. Specifically, in this embodiment, the first joining component 104 has a first joining portion 1041 and two second joining portions 1042. The first joining portion 1041 corresponds to the winding body 1020, and the two second joining portions 1042 correspond to the first lead 1021 and the second lead 1022, so that the winding body 1020, the first lead 1021 and the second lead 1022 are fixed to the first base 106 by the first joining component 104.

[0145] Similar to the aforementioned embodiments, the second base 108 has a first side plate 1081 and a second side plate 1082, and as shown in the previous embodiments... Figure 6 and Figure 7 As shown, the first side plate 1081 may have a receiving groove RC1 configured to receive the coil assembly 102 and the first base 106. The shape of the receiving groove RC1 corresponds to the shape of the first base 106.

[0146] When viewed along the winding axis RX (Z-axis), the second base 108 has a rectangular structure with four sides, and the receiving groove RC1 is disposed on one of the four sides. In this embodiment, the receiving groove RC1 is disposed on the left side of the second base 108, but is not limited thereto. For example, in other embodiments, the receiving groove RC1 is disposed on the right side of the second base 108.

[0147] like Figure 7 As shown, the first side plate 1081 has a first layer LY1 and a second layer LY2, at least a portion of the receiving groove RC1 is located between the first layer LY1 and the second layer LY2, and the first electrical contact EC1 and the second electrical contact EC2 are located in the first side plate 1081.

[0148] For example, the first electrical contact EC1 and the second electrical contact EC2 are disposed on the first layer LY1, for example in Figure 7 It is placed at the bottom of the first layer, LY1. It is worth noting that, as... Figure 6 As shown, when viewed along the winding axis RX, the first electrical contact EC1 and the second electrical contact EC2 are completely shielded by the first layer LY1. That is, the first electrical contact EC1 and the second electrical contact EC2 are embedded in the second base 108 and are not exposed by the first layer LY1.

[0149] In this embodiment, the first electrical contact EC1 and the second electrical contact EC2 may be pogo pins, but are not limited to this. The positions of the first electrical contact EC1 and the second electrical contact EC2 correspond to the first lead 1021 and the second lead 1022.

[0150] In this embodiment, the coil assembly 102, the first engagement assembly 104, and the first base 106 are detachably inserted into or removed from the receiving slot RC1. When inserted into the receiving slot RC1, the first lead 1021 and the second lead 1022 are supported by the first base 106, thus allowing them to smoothly contact the first electrical contact EC1 and the second electrical contact EC2 without any misalignment.

[0151] It should also be noted that, in addition to the first layer LY1 and the second layer LY2, the first side panel 1081 in this embodiment may also include other layers disposed between the first layer LY1 and the second layer LY2. That is, in this embodiment or other embodiments, the number of layers of the first side panel 1081 is not limited to two.

[0152] Please refer to the following: Figure 8 as well as Figure 9 . Figure 8 This is a perspective view of a wireless transmission module 100B according to another embodiment of the present invention, and Figure 9 For the wireless transmission module 100B according to another embodiment of the present invention along Figure 8 A cross-sectional view of the center segment CC. Wireless transmission module 100B and wireless transmission module 100A may have the same components and similar configurations.

[0153] For example, the shape of the first engaging component 104 corresponds to the shape of the winding body 1020, such that the winding body 1020 can be fixed to the first base 106 via the first engaging component 104. In this embodiment, as... Figure 8 As shown, when viewed along the winding axis RX, a portion of the first lead 1021 and the second lead 1022 do not overlap with the first base 106.

[0154] Furthermore, such as Figure 9 As shown, the first electrical contact EC1 and the second electrical contact EC2 are disposed on the second layer LY2. In this embodiment, the first electrical contact EC1 and the second electrical contact EC2 are, for example, metal contacts for welding, but are not limited thereto.

[0155] It is worth noting that, such as Figure 8 and Figure 9 As shown, the second base 108 also has an exposed opening 108H, formed on the first layer LY1. When viewed along the winding axis RX, as... Figure 8 As shown, the first electrical contact EC1 and the second electrical contact EC2 are exposed through the exposure port 108H.

[0156] When the coil assembly 102, the first engagement assembly 104 and the first base 106 are detachably inserted into the receiving slot RC1, and when viewed along the winding axis RX, a portion of the first lead 1021 and the second lead 1022 are also exposed through the exposure port 108H.

[0157] Since the positions of the first electrical contact EC1 and the second electrical contact EC2 correspond to the first lead 1021 and the second lead 1022, when viewed along the winding axis RX, the first lead 1021 and the second lead 1022 are respectively overlapping a portion of the first electrical contact EC1 and the second electrical contact EC2.

[0158] Based on the above configuration, the operator can conveniently solder the first lead 1021 and the second lead 1022 through the exposed opening 108H. Since the first lead 1021 and the second lead 1022 do not protrude from the exposed opening 108H, it can be ensured that the first lead 1021 and the second lead 1022 will not come into contact with external components and cause damage.

[0159] Please refer to the following: Figure 10 . Figure 10 This is a perspective view of a wireless transmission module 100C according to another embodiment of the present invention. The wireless transmission module 100C is similar to the wireless transmission module 100A, for example, the first side plate 1081 has a receiving groove RC1 configured to receive the coil assembly 102 and the first base 106.

[0160] In this embodiment, the first side plate 1081 also has a first layer LY1 and a second layer LY2, and the first layer LY1 is directly connected to the second layer LY2. Furthermore, the first side plate 1081 also has a third layer LY3 and a fourth layer LY4, the receiving groove RC1 is formed on the first layer LY1 to the third layer LY3, and the first electrical contact EC1 and the second electrical contact EC2 are located on the fourth layer LY4.

[0161] The receiving slot RC1 is configured to accommodate the first base 106, the winding body 1020, the first electrical contact EC1, the second electrical contact EC2, the first lead 1021, and the second lead 1022.

[0162] When viewed along the winding axis RX, the second base 108 has a rectangular structure, and when viewed along the winding axis RX, the receiving groove RC1 is formed by a recess on one side 1085 of the rectangular structure.

[0163] In addition, when viewed along the winding shaft RX, the first electrical contact EC1, the second electrical contact EC2, the first lead 1021 and the second lead 1022 are exposed from the first layer LY1 to facilitate soldering of the first lead 1021 and the second lead 1022.

[0164] It is worth noting that in this embodiment, the wireless transmission module 100C may also have a protection component 112. After the first lead 1021 and the second lead 1022 are soldered, the protection component 112 may be disposed in the receiving groove RC1 to cover the first lead 1021 and the second lead 1022, thereby ensuring that the first lead 1021 and the second lead 1022 are not damaged by collisions with external components.

[0165] The protective component 112 may be, for example, a single-sided tape or a U-shaped plastic cover, but is not limited thereto. Any component whose shape corresponds to the receiving groove RC1 and can cover and protect the first lead 1021 and the second lead 1022 falls within the scope of this utility model.

[0166] Please refer to the following: Figure 11 as well as Figure 12 . Figure 11 This is a perspective view of a wireless transmission module 100D according to another embodiment of the present invention, and Figure 12 According to another embodiment of the present invention, the wireless transmission module 100D is along... Figure 11 A cross-sectional view of the middle segment DD. Wireless transmission module 100D and wireless transmission module 100A may have the same components and similar configurations.

[0167] For example, the shape of the first engaging component 104 corresponds to the shape of the winding body 1020, such that the winding body 1020 can be fixed to the first base 106 via the first engaging component 104. In this embodiment, as... Figure 11 and Figure 12 As shown, when viewed along the winding axis RX, a portion of the first lead 1021 and the second lead 1022 do not overlap with the first base 106.

[0168] In this embodiment, the first side plate 1081 has a receiving groove RC1, configured to receive the coil assembly 102, the first base 106, the first joining assembly 104, the second joining assembly 110, and the protective assembly 111. The first base 106 is disposed between the coil assembly 102 and the second base 108.

[0169] The first side panel 1081 also has a first layer LY1 and a second layer LY2. Specifically, as follows Figure 12 As shown, the first layer LY1 is directly connected to the second layer LY2.

[0170] The receiving groove RC1 is formed on the first layer LY1, and a portion of the shape of the receiving groove RC1 corresponds to the shape of the first base 106. For example, when viewed along the direction of the winding shaft RX, a portion of the receiving groove RC1 has a rectangular structure.

[0171] In this embodiment, the receiving groove RC1 has a first receiving portion RC2 and a second receiving portion RC3. The first receiving portion RC2 is connected to the second receiving portion RC3, and the first receiving portion RC2 has a rectangular shape.

[0172] In this embodiment, the first accommodating portion RC2 is configured to accommodate the first base 106 and the winding body 1020, and the second accommodating portion RC3 is configured to accommodate the first electrical contact EC1, the second electrical contact EC2, the first lead 1021, and the second lead 1022. Figure 11 and Figure 12 As shown, the first electrical contact EC1 and the second electrical contact EC2 are located on the second layer LY2.

[0173] like Figure 11 As shown, the second base 108 defines a first axis AX1 and a second axis AX2, the first axis AX1 being perpendicular to the second axis AX2, and the winding axis RX being perpendicular to both the first axis AX1 and the second axis AX2. When viewed along the first axis AX1 (Y-axis), the first lead 1021 and the second lead 1022 overlap the first layer LY1, and when viewed along the second axis AX2 (X-axis), the first lead 1021 and the second lead 1022 also overlap the first layer LY1.

[0174] When viewed along the winding shaft RX, the second base 108 has a rectangular structure, and the first receiving portion RC2 is disposed in a central region 108C of the rectangular structure. The winding shaft RX passes through the central region 108C and the first receiving portion RC2.

[0175] When viewed along the winding axis RX, this rectangular structure has four sides, and the second receiving portion RC3 is disposed at one of the four sides. Specifically, when viewed along the winding axis RX, the rectangular structure has a first side 1083, and the second receiving portion RC3 is located at the first side 1083.

[0176] When viewed along the winding axis RX, the first layer LY1 has a horseshoe-shaped structure, and the shape of the protective assembly 111 is approximately the same as that of the second engagement assembly 110 when viewed along the winding axis RX. Figure 12 As shown, and the protective component 111 has a generally rectangular structure, such as Figure 11 As shown.

[0177] like Figure 11As shown, when viewed along the winding axis RX, the second receiving portion RC3 does not overlap with the winding body 1020. The first lead 1021 and the second lead 1022 extend outward from the winding body 1020 to the first electrical contact EC1 and the second electrical contact EC2, and a portion of the first lead 1021 and the second lead 1022 are located in the second receiving portion RC3.

[0178] Similarly, in this embodiment, the protective component 111 is disposed between the coil assembly 102 and the first base 106. For example, the protective component 111 is a plastic sheet, such as one made of PET material, configured to engage and protect the first base 106. It should be noted that the configuration of the protective component 111 is not limited to this embodiment, and it may also be disposed on the first base 106 of the aforementioned wireless transmission modules 100A to 100C.

[0179] Next, in this embodiment, as Figure 12 As shown, the first accommodating portion RC2 has a first depth HT1, the second accommodating portion RC3 has a second depth HT2, and the first depth HT1 is approximately equal to the second depth HT2.

[0180] Additionally, it is worth noting that the coil assembly 102, the first bonding assembly 104, the first base 106, the protective assembly 111, and the second bonding assembly 110 have a total height HT3, which is less than the first depth HT1. This configuration ensures that the winding body 1020 is not damaged by collisions with external components.

[0181] Furthermore, it should be noted that, for the sake of brevity, the wiring, first through hole VA1, second through hole VA2, and electronic components are not described again in wireless transmission modules 100A to 100D. In fact, wireless transmission modules 100A to 100D may still have similar wiring, first through hole VA1, second through hole VA2, and electronic components as wireless transmission module 100.

[0182] In summary, this utility model provides a wireless transmission module 100, which includes a coil assembly 102, a first base 106, and a second base 108. The coil assembly 102 and the first base 106 are disposed on a first side plate 1081 of the second base 108, and multiple electronic components are disposed on a second side plate 1082 of the second base 108. Since all electronic components are disposed on the second side plate 1082, the process time of surface mount technology can be reduced by half, and it is also convenient for operators to install the coil assembly 102 on the first side plate 1081, increasing the ease of assembly.

[0183] Additionally, the second base 108 can be a printed circuit board, and a receiving groove RC1 can be formed on the first side plate 1081. The receiving groove RC1 is configured to accommodate the coil assembly 102 and the first base 106. Based on this configuration, the overall thickness of the wireless transmission module can be significantly reduced, thereby achieving the goal of thinness.

[0184] Furthermore, the coil assembly 102 and the first base 106 are detachably inserted into or removed from the receiving slot RC1, for example, by being inserted into the receiving slot RC1 from the top surface or side of the second base 108. Based on this structural design, damaged coil assemblies 102 can be easily replaced, or coil assemblies of the same size but different functions can be replaced. Therefore, the same second base 108 can be used, thereby reducing overall production costs.
