Description

Wireless transmission module

Technical Field

The present disclosure relates to a wireless transmission module, and more particularly, to a wireless transmission module applied to wireless communication or wireless charging.

Background

With the development of technology, many electronic devices (such as tablet computers or smart phones) have wireless charging function. The user can place the electronic device on a wireless charging transmitting end, so that the wireless charging receiving end in the electronic device can charge the battery by utilizing an electromagnetic induction mode or an electromagnetic resonance mode to generate current. Due to the convenience of wireless charging, electronic devices with wireless charging modules are also increasingly popular.

Generally, the wireless charging module includes a magnetically permeable substrate carrying a coil. When the coil is electrified to operate in a wireless charging mode or a wireless communication mode, the magnetic permeability substrate can make magnetic force lines emitted by the coil more concentrated so as to obtain better efficiency. However, the structure of the conventional wireless charging (or communication) module and the winding manner of the coil cannot meet various requirements for the wireless transmission module, such as better charging, communication performance and more miniaturized size.

Therefore, how to design a wireless transmission module that can meet various requirements of users is a problem to be studied and solved.

Referring to fig. 1 and 2, fig. 1 is a perspective view of a wireless transmission module 100 according to an embodiment of the disclosure, and fig. 2 is an exploded view of the wireless transmission module 100 according to an embodiment of the disclosure. As shown in fig. 1, a wireless transmission module 100 is a wireless transmission module that may be used to transmit energy or signals.

The induction base 106 may be a magnetic body, such as Ferrite (Ferrite), but is not limited thereto. For example, in other embodiments, the susceptor 106 may also include a nanocrystalline material. The induction base 106 may have a magnetic permeability corresponding to the first circuit component 102, so that the electromagnetic waves of the first circuit component 102 are more concentrated.

The first adhesive element 104 may be a double sided adhesive or a single sided adhesive for adhering to one or two adjacent components. In some embodiments, the first adhesive element 104 may be made of polyethylene terephthalate (PET), but is not limited thereto. For example, the first adhesive element 104 may also be made of polypropylene (PP).

Referring next to fig. 1 to 4, fig. 3 is a top view of an assembled wireless transmission module 100 according to an embodiment of the disclosure, and fig. 4 is a schematic cross-sectional view of the assembled wireless transmission module 100 along a line A-A in fig. 3 according to an embodiment of the disclosure. As shown in fig. 2 and 3, the wireless transmission module 100 defines a first axial direction AX1 and a second axial direction AX2, and the first axial direction AX1 is perpendicular to the second axial direction AX2. For example, the first axial direction AX1 is parallel to the Y axis, the second axial direction AX2 is parallel to the X axis, and the first axial direction AX1, the second axial direction AX2, and the winding axis RX are perpendicular to each other.

In this embodiment, the first circuit assembly 102 has a body 1020 and at least one first lead 1021 and at least one second lead 1022, and the body 1020 has the winding shaft RX. The extending direction of the at least one first lead-out wire 1021 is not parallel to the winding axis RX, and the extending direction of the at least one first lead-out wire 1021 is parallel to the extending direction of the at least one second lead-out wire 1022.

In this embodiment, the sensing base 106 has a plate-like structure, and the sensing base 106 forms a plurality of accommodating grooves 106RC configured to accommodate the body 1020 of the first circuit component 102. The sensing base 106 has a first surface 106S1, and the accommodating grooves 106RC are recessed from the first surface 106S1.

Each of the receiving grooves 106RC has a concave surface 106RS configured to carry windings of the body 1020. The sensing base 106 further has a second surface 106S2, and the first surface 106S1 and the second surface 106S2 are located at opposite sides of the plate-like structure.

The first surface 106S1 is a plane, and when viewed along a first direction D1 perpendicular to the winding axis RX (fig. 4), at least one first lead 1021 does not overlap the first surface 106S1. Wherein the first direction D1 is parallel to the first axial direction AX1.

These concave surfaces 106RS are located between the first surface 106S1 and the second surface 106S2 when viewed along the first direction D1. It should be noted that, when viewed along the first direction D1, the distances between the concave surfaces 106RS and the first surface 106S1 along the winding axis RX are the same.

As shown in fig. 2, the susceptor 106 may further include a first lead-out wire groove 1061 configured to receive at least one first lead-out wire 1021. Similarly, the susceptor 106 may further include a second lead wire channel 1062 configured to receive at least one second lead wire 1022.

The first lead out groove 1061 is formed by the first surface 106S1 being recessed in the direction of the winding axis RX, and the second lead out groove 1062 is formed by the first surface 106S1 being recessed in the direction of the winding axis RX.

When viewed along the first direction D1, the first bearing surface 1063 and the second bearing surface 1064 are located between the first surface 106S1 and the second surface 106S2. When viewed along the first direction D1, the first surface 106S1 and the second surface 106S2 have a first distance DS1 therebetween.

When viewed along the first direction D1, the first bearing surface 1063 and the second surface 106S2 have a second distance DS2 therebetween. In this embodiment, the second distance DS2 is at most forty percent of the first distance DS1.

Furthermore, a third distance DS3 is provided between the first surface 106S1 and the first supporting surface 1063.

The fourth distance DS4 is greater than the diameter of the at least one second lead line 1022, and the fourth distance DS4 is greater than the third distance DS3. Thus, the second lead wire groove 1062 may fully receive the second lead wire 1022 therein.

Please refer to fig. 4 and 5, and fig. 5 is a bottom view of a portion of the structure of the wireless transmission module 100 according to an embodiment of the disclosure. In this embodiment, the wireless transmission module 100 may further include a heat dissipation structure 130 fixedly disposed on the second surface 106S2.

Wherein the heat dissipation structure 130 includes a plurality of protrusions 1301, and the protrusions 1301 extend along the first direction D1 when viewed along the direction of the winding axis RX. It should be noted that the heat dissipation structure 130 is integrally formed with the induction base 106. Because the power of the first circuit assembly 102 of the present disclosure is greater (e.g., 30W to 50W) than that of a typical coil, the inductive pedestal 106 can be made to quickly and efficiently assist the first circuit assembly 102 in dissipating heat based on such a design.

And then returns to fig. 2 and 4. In this embodiment, the first adhesive element 104 is disposed between the body 1020 and the sensing base 106, and the first adhesive element 104 may include a plurality of first adhesive members 1040 disposed in the corresponding first lead-out grooves 1061, the second lead-out grooves 1062, and the receiving grooves 106RC, respectively.

The first adhesive members 1040 are shaped to correspond to the receiving grooves 106RC, the first lead out grooves 1061, and the second lead out grooves 1062 to secure the first circuit assembly 102 to the induction base 106.

As shown in fig. 2 to 4, the sensing base 106 further has a protruding structure 106P protruding from the first surface 106S1 along the direction of the winding axis RX. The spool RX passes through the protruding structure 106P, and the body 1020 does not overlap the protruding structure 106P when viewed along the direction of the spool RX.

The body 1020 surrounds the projection 106P when viewed in the direction of the spool RX. The first lead out groove 1061 is not connected to the projection structure 106P when viewed in the direction of the spool RX. The second lead out groove 1062 is connected to the protruding structure 106P when viewed in the direction of the spool RX.

Furthermore, as shown in fig. 4, the body 1020 does not overlap the protruding structure 106P when viewed along the first direction D1. Based on such a structural configuration, not only the efficiency of the first circuit component 102 can be increased, but also the purpose of miniaturization can be achieved.

Furthermore, in this embodiment, the wireless transmission module 100 may further include a heat dissipation element 150 disposed on the first surface 106S1 and disposed in the first lead-out groove 1061, the second lead-out groove 1062 and the receiving groove 106RC.

The heat dissipation element 150 may encapsulate the body 1020 and the protruding structure 106P, and the heat dissipation element 150 is made of a non-metal material. For example, the heat dissipation device 150 is a thermal paste (thermal paste) made of a non-metal material, but is not limited thereto.

In addition, the wireless transmission module 100 may further include an adhesive element 112 configured to adhere to the heat dissipation element 150, such that the heat dissipation element 150 is located between the adhesive element 112 and the sensor base 106.

Specifically, the adhesive element 112 encapsulates the heat dissipation element 150 and adheres to the first surface 106S1. When viewed along the first direction D1, the adhesive element 112 does not overlap the first lead out groove 1061. When viewed along the first direction D1, the adhesive element 112 does not overlap the second lead out groove 1062.

The adhesive element 112 does not overlap the accommodating grooves 106RC when viewed along the first direction D1. When viewed along the direction of the winding axis RX, the adhesive element 112 overlaps the first lead-out wire groove 1061, the second lead-out wire groove 1062, and the accommodating grooves 106RC.

In this embodiment, the adhesive element 112 is made of plastic material. For example, the adhesive element 112 may be a double sided tape made of polyethylene terephthalate (PET), but is not limited thereto.

Based on the above-described structural configuration, the heat dissipation member 150 can be stably fixed to the first circuit assembly 102, and the heat energy generated by the first circuit assembly 102 can be effectively reduced. Furthermore, such a design may also avoid particle generation problems with the susceptor 106 and may enhance the structural strength of the susceptor 106.

Referring next to fig. 3 to 6, and fig. 6 is a schematic view of the sensor base 106 according to an embodiment of the present disclosure mounted on the housing 11 of an external device 10. The sensor base 106 may further include a through hole 106H formed in the protruding structure 106P, and the through hole 106H is located between two adjacent protruding portions 1301 when viewed along the direction of the winding axis RX.

Correspondingly, the wireless transmission module 100 may further include a locking element SCE configured to pass through the through hole 106H and connect to the housing 11 of the external device 10. The locking element SCE is, for example, a screw, and is configured to abut against an inner wall surface of the through hole 106H, so as to lock the sensing base 106 to the housing 11.

Based on such a structural configuration, not only the miniaturization purpose can be achieved, but also the heat of the first circuit assembly 102 can be quickly conducted to the housing 11 (e.g. made of metal material) through the locking element SCE, so as to further increase the heat dissipation efficiency.

Referring to fig. 7 and 8, fig. 7 is a perspective view of a wireless transmission module 100A according to another embodiment of the present disclosure, and fig. 8 is a bottom view of the wireless transmission module 100A according to another embodiment of the present disclosure. This embodiment is similar to the previous embodiment except that the susceptor 106 includes a first segment SG1 and a second segment SG2.

The first segment SG1 is connected to the second segment SG2, and the first segment SG1 and the second segment SG2 are integrally formed. As shown in fig. 7, the first circuit component 102 is disposed on the first section SG1, and the second circuit component 103 is disposed on the second section SG2.

When viewed along a second direction D2, a first thickness TH1 of the first section SG1 on the winding axis RX (Z axis) is different from a second thickness TH2 of the second section SG2 on the winding axis RX.

For example, the first thickness TH1 is larger than the second thickness TH2 when viewed along the second direction D2, and the second direction D2 is perpendicular to the first direction D1 and the winding axis RX.

Further, as shown in fig. 8, the first segment SG1 and the second segment SG2 extend along the first direction D1 when viewed along the direction of the winding axis RX. These protruding portions 1301 are provided to the first segment SG1 when viewed in the direction of the spool RX. The second circuit component 103 does not overlap the projections 1301 when viewed in the direction of the winding axis RX.

Note that the first thickness TH1 is a height including the protruding portion 1301, and the second thickness TH2 does not include a height of the protruding portion 1301. Therefore, according to the structural design of the induction base 106A of this embodiment, not only the purpose of miniaturization can be achieved, but also the heat dissipation effect can be increased by the second segment SG2 disposed at the bottom of the second circuit assembly 103.

Referring next to fig. 9, fig. 9 is a perspective view of a wireless transmission module 100B according to another embodiment of the disclosure. This embodiment is similar to the previous embodiment, except that the sensing base 106B of this embodiment further has a first opening OP1 in communication with the first lead-out wire groove 1061 and the second lead-out wire groove 1062.

The first opening OP1 is formed toward the second circuit assembly 103, the second circuit assembly 103 is provided with an airflow generating element 1032, and an air outlet 1033 of the airflow generating element 1032 is toward the first opening OP1. The airflow generating element 1032 may be, for example, a fan or a micro-motor configured exhaust element, but is not limited thereto.

Furthermore, the sensing base 106B is further formed with a second opening OP2, and the first opening OP1 and the second opening OP2 are located at opposite sides of the first circuit component 102 when viewed along the direction of the winding axis RX.

When viewed along a third direction D3, the body 1020 is exposed by the second opening OP2, wherein the third direction D3 is opposite to the first direction D1 and perpendicular to the second direction D2.

When viewed along the second direction D2, a portion of the susceptor 106B does not overlap the body 1020. Further, the airflow generating element 1032 is located between the first and second lead wires 1021 and 1022 when viewed along the direction of the spool RX. With such a configuration, the air blown out by the airflow generating element 1032 can enter through the first opening OP1, blow out through the body 1020, and then blow out through the second opening OP2, so as to effectively take away the heat generated by the first circuit assembly 102.

In addition, in this embodiment, the sensing base 106B may further be formed with a plurality of groove structures 106RT recessed along the second direction D2 (second axis AX 2).
