[0030] Reference below Figures 1-6 A wireless charging device 100 according to an embodiment of the present invention is described.

[0031] Example 1:

[0032] like Figure 1 and Figure 2 As shown, this embodiment provides a wireless charging device 100 , which includes a bracket assembly 1 and a wireless charging unit 2 .

[0033] The wireless charging unit 2 includes a charging module 21 and a heat dissipation module 23. The charging module 21 has a charging end surface 211, and the heat dissipation module 23 is arranged on a side of the charging module 21 away from the charging end surface 211.

[0034] In the process of charging the electrical device, part of the electrical energy of the charging module 21 is converted into heat energy, and the heat energy is transferred from the charging module 21 to the electrical device, which causes the charging module 21 and the electrical device to heat up seriously, affecting the life of the wireless charging unit 2 and the electrical device. When the charging module 21 is connected to the electrical device, the charging end surface 211 of the charging module 21 is attached to the electrical device, and the electrical device is covered by the charging module 21, resulting in poor ventilation and low cooling efficiency. After a period of charging, the temperature of the electrical device and the charging module 21 rises, resulting in reduced charging efficiency. The cause and effect are still not clear.

[0035] By setting the heat dissipation module 23 on the side of the charging module 21 away from the charging end surface 211, the heat dissipation module 23 and the charging module 21 can fully exchange heat, and the charging module 21 can be thermally compensated during the charging process, thereby reducing the temperature of the charging module 21 and the electrical equipment.

[0036] The heat dissipation module 23 here can adopt an active heat dissipation structure, a passive heat dissipation structure, or a combination of the two.

[0037] In some optional examples, the active heat dissipation structure includes a cooling fan, and the charging module 21 is electrically connected to the cooling fan. When the wireless charging device 100 is charging an electrical device, the cooling fan is connected to the power source and activated, generating airflow toward the second side 102 of the bracket assembly 1, thereby removing heat from the charging module 21.

[0038] In other optional examples, the passive heat dissipation structure is a heat sink, and the heat sink can be made of a material with a higher thermal conductivity coefficient to improve the heat exchange efficiency; and\or, the area of ​​the heat sink is larger than the area of ​​the charging module 21 to increase the heat dissipation area and improve the heat exchange efficiency.

[0039] In some more specific embodiments, the portion of the bracket assembly 1 that is connected to or in contact with the heat sink is a metal structure with high heat transfer efficiency. Since the bracket assembly 1 has a larger surface area, the combination of the two can expand the heat dissipation area and improve the heat dissipation effect.

[0040] In some optional examples, the heat dissipation module 23 adopts a combination of active heat dissipation structure and passive heat dissipation structure. In this structure, both can be set on the charging module, for example, the heat sink is set between the charging module 21 and the heat dissipation fan.

[0041] In this embodiment, if Figure 1 and Figure 2 As shown, the bracket assembly 1 has a first side 101 and a second side 102. The first side 101 of the bracket assembly 1 is used to place an electrical device. The bracket assembly 1 has a mounting opening 10 extending from the first side 101 to the second side 102. When the wireless charging unit 2 is mounted on the bracket assembly 1, the charging end surface 211 is attached to the electrical device through the mounting opening 10 to charge the device. The heat dissipation module 23 is located on the back of the charging module 21 to dissipate heat from the charging module 21 and transfer the heat to the second side 102.

[0042] It should be further explained that the first side 101 and the second side 102 can be positioned away from each other; alternatively, the first side 101 and the second side 102 can be positioned adjacent to each other. The first side 101 and the second side 102 herein are merely used to define that when the wireless charging unit 2 is mounted on the bracket assembly 1, the power supply side and the heat dissipation side of the wireless charging unit 2 are different, thereby transferring heat generated during wireless charging to the heat dissipation unit, thereby cooling the charging unit and the electrical device. This does not indicate or imply that the wireless charging unit 2 must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as a limitation on the present invention.

[0043] For example, the first side 101 is the front side of the bracket assembly 1, and the second side 102 is the rear side of the bracket assembly 1, or the second side 102 is located at the top or bottom of the bracket assembly 1, or the second side 102 is located at the left or right side of the bracket. In conjunction with the embodiment of the active heat dissipation structure, one or more of the front, left, right, top, or bottom of the bracket assembly 1 can be provided with an opening, and the opening can pass through the airflow generated by the heat dissipation fan.

[0044] It is understood that when the first side 101 is the top of the stand assembly 1, the second side 102 can be the bottom facing away from the top, or the front, rear, left, or right side adjacent to the top. When in use, the wireless charging unit 2 of this embodiment has two different usage modes depending on the assembly relationship between the wireless charging unit 2 and the stand assembly 1.

[0045] When the wireless charging unit 2 is installed on the bracket assembly 1 through the mounting port 10, the charging end surface 211 of the charging module 21 faces the first side 101, and the electrical device can be placed on the first side 101 of the bracket assembly 1 for charging; the heat dissipation module 23 dissipates heat and cools the charging module 21 and the electrical device, and transfers the heat of the charging module 21 and the electrical device to the second side 102, thereby improving the charging efficiency and reducing the damage to the charging module 21 and the electrical device caused by high temperature during the charging process.

[0046] When the wireless charging unit 2 is separated from the bracket assembly 1 , the wireless charging unit 2 is connected to the power-consuming device and moves along with the power-consuming device, so the position of the wireless charging unit 2 is more flexible.

[0047] Thus, the wireless charging unit 2 can be detachably mounted on the bracket assembly 1 through the mounting opening 10. When the wireless charging unit 2 is connected to the bracket assembly 1, the electrical device is placed on the first side 101 of the bracket assembly 1 for charging, and the bracket assembly 1 provides support for the wireless charging unit 2 and the electrical device. The wireless charging unit 2 can also be separated from the bracket assembly 1. The wireless charging unit 2 can be connected to the electrical device and move with the electrical device, making it more flexible and convenient to use. The heat dissipation module 23 dissipates heat and cools the charging module 21 and the electrical device, improving charging efficiency and reducing damage to the charging module 21 and the electrical device caused by high temperatures during charging.

[0048] Example 2:

[0049] like Figure 3 and Figure 4 As shown, this embodiment is basically the same as the first embodiment, with the difference that: a first magnetic member 31 is provided in the bracket assembly 1, and a second magnetic member 32 is provided on the wireless charging unit 2; when the wireless charging unit 2 is installed on the bracket assembly 1, the first magnetic member 31 can be magnetically engaged with the second magnetic member 32 to fix the wireless charging unit 2 on the bracket assembly 1.

[0050] Furthermore, the first magnetic member 31 may be arranged at the edge of the mounting opening 10 , which may achieve a better fixing effect and lower arrangement cost.

[0051] During use of this embodiment, when the wireless charging unit 2 is separated from the stand assembly 1, the first magnetic member 31 moves away from the second magnetic member 32, releasing the fixation between the wireless charging unit 2 and the stand assembly 1. This simplifies assembly of the wireless charging unit 2 and the stand assembly 1, reduces the number of steps, and makes assembly more convenient.

[0052] like Figure 3 and Figure 4 As shown, further, a plurality of second magnetic members 32 are spaced apart and arranged around the charging end surface 211. After at least one second magnetic member 32 is magnetically engaged with at least one first magnetic member 31, the position and posture of the wireless charging unit 2 are further adjusted, so that the wireless charging unit 2 is installed in place, and the charging end surface 211 of the charging module 21 is fixed on the bracket assembly 1, thereby improving the stability and reliability of the connection between the wireless charging unit 2 and the bracket assembly 1.

[0053] Furthermore, the number of the first magnetic members 31 and the number of the second magnetic members 32 may be the same.

[0054] Furthermore, after the wireless charging unit 2 is installed in place, the second magnetic member 32 corresponds to the first magnetic member 31 in position.

[0055] For example, the number of the second magnetic members 32 may be 2, 3, 4, 8, etc. Correspondingly, the number of the first magnetic members 31 is the same as the number of the second magnetic members 32 , and the number of the second magnetic members 32 is not limited here.

[0056] like Figure 3 and Figure 4 As shown, multiple second magnetic members 32 are evenly spaced along the circumference. Correspondingly, first magnetic members 31 are evenly spaced along the circumference at the edge of the mounting opening 10. By rotating the angle between the wireless charging unit 2 and the bracket assembly 1, the positions of the second magnetic members 32 and the first magnetic members 31 are aligned one-to-one, allowing the wireless charging unit 2 to be fixed to the bracket assembly 1. This arrangement can further improve the convenience of assembly.

[0057] like Figure 3 and Figure 4As shown, further, the bracket assembly 1 extends from the edge of the mounting opening 10 to the middle of the mounting opening 10 to form a limiting flange 14; when the wireless charging unit 2 is installed on the bracket assembly 1, the wireless charging unit 2 rests on the end surface of the limiting flange 14 facing the first side 101 or the second side 102, so that the wireless charging unit 2 can be positioned in the installation position when installed to the bracket assembly 1, further improving the convenience of assembly.

[0058] like Figure 3 and Figure 4 As shown, further, the first magnetic member 31 can be embedded in the limiting flange 14, and the wireless charging unit 2 rests on the end face of the limiting flange 14 facing the first side 101 or the second side 102, and the second magnetic member 32 in the wireless charging unit 2 and the first magnetic member 31 in the limiting flange 14 are magnetically engaged.

[0059] Example 3:

[0060] This embodiment is substantially the same as the first embodiment, except that a first magnetic member 31 is provided within the bracket assembly 1, and a second magnetic member 32 is provided on the wireless charging unit 2. When the wireless charging unit 2 is mounted on the bracket assembly 1, the first magnetic member 31 can magnetically engage with the second magnetic member 32 to secure the wireless charging unit 2 to the bracket assembly 1. The wireless charging unit is provided with a second magnetic member that extends in a direction surrounding the charging end surface.

[0061] like Figure 3 and Figure 4 As shown, further, the bracket assembly 1 extends from the edge of the mounting opening 10 to the middle of the mounting opening 10 to form a limiting flange 14; when the wireless charging unit 2 is installed on the bracket assembly 1, the wireless charging unit 2 rests on the end surface of the limiting flange 14 facing the first side 101 or the second side 102, so that the wireless charging unit 2 can be positioned in the installation position when installed to the bracket assembly 1, further improving the convenience of assembly.

[0062] like Figure 3 and Figure 4 As shown, further, the first magnetic member 31 can be embedded in the limiting flange 14, and the wireless charging unit 2 rests on the end face of the limiting flange 14 facing the first side 101 or the second side 102, and the second magnetic member 32 in the wireless charging unit 2 and the first magnetic member 31 in the limiting flange 14 are magnetically engaged.

[0063] Example 4:

[0064] like Figure 5-Figure 6As shown, this embodiment is substantially the same as the first embodiment, with the difference being that the bracket assembly 1 is provided with an elastic structural layer 15 at the mounting opening 10. When the wireless charging unit 2 is mounted on the bracket assembly 1, the elastic structural layer 15 is under stress and has a tendency to return to its initial state. The wireless charging unit 2 is positioned at the mounting opening 10 and compresses the elastic structural layer 15 provided at the mounting opening 10. The elastic structural layer 15 has a tendency to return to its initial state and abuts against the outer surface of the wireless charging unit 2, locking the wireless charging unit 2 at the mounting opening 10 and achieving a fixed connection between the wireless charging unit 2 and the bracket assembly 1.

[0065] Furthermore, the elastic structural layer 15 is made of silicone material.

[0066] Embodiment 5:

[0067] like Figure 5-Figure 6 As shown, this embodiment provides a bracket assembly 1, which further defines the bracket assembly 1 based on the first embodiment.

[0068] Furthermore, the bracket assembly 1 includes a base 13 and a charging seat 12 connected to each other, and the charging seat 12 is arranged to be inclined relative to the base 13; the mounting port 10 is opened on the charging seat 12.

[0069] The stand assembly 1 comprises a base 13 and a charging cradle 12. The base 13 and charging cradle 12 can form an L-shaped, C-shaped, or Z-shaped structure. It is understood that the base 13 is intended to be placed on a support. There is a certain angle between the charging cradle 12 and the base 13, which facilitates the placement of the charging object.

[0070] The base 13 and the charging seat 12 form an L shape, and the connecting portion between the two can be deformed. That is, in a specific implementation plan of this embodiment, the bracket assembly 1 consists of a base 13, a deformable portion and a charging seat 12, wherein the deformable portion is used to connect the base 13 and the charging seat 12, so that the position between the base 13 and the charging seat 12 can change relative to each other.

[0071] Furthermore, the stand assembly 1 further includes a mounting housing 11 fixed to the charging base 12. The mounting housing 11 defines a mounting cavity 111 therein, which communicates with the mounting opening 10. When the wireless charging unit 2 is mounted on the stand assembly 1, the wireless charging unit 2 is accommodated within the mounting cavity 111. This improves the stability and reliability of the connection between the stand assembly 1 and the wireless charging unit.

[0072] Furthermore, the mounting housing 11 is provided with a wire hole 112, which is in communication with the mounting cavity 111. When the wireless charging unit 2 is mounted on the bracket assembly 1, the wireless charging unit 2 is accommodated in the mounting cavity 111, and the electrical connector 22 of the wireless charging unit 2 can be connected to a power source through the wire hole 112.

[0073] Furthermore, the stand assembly 1 may also be provided with one or a combination of active and passive heat dissipation structures. For example, a passive heat dissipation structure may be provided on the charging module 21, while an active heat dissipation structure may be provided on the charging base 12 of the stand assembly 1. Of course, the active heat dissipation structure may also be provided on the base 13. This configuration will improve the heat dissipation effect brought about by airflow to a certain extent, but it will also result in the charging module 21 being able to dissipate heat only through the passive heat dissipation structure when used separately from the stand assembly 1.

[0074] Optionally, a cooling fan is provided on the base 13 to form an airflow from the base to the passive cooling structure, thereby increasing heat exchange between the passive cooling structure and the air; in this structure, a larger cooling structure is formed by connecting the connecting part of the bracket assembly 1 and the charging module 21 with the passive cooling structure, and through this structural setting, the airflow generated by the cooling fan can achieve a better cooling effect.

[0075] In some specific implementations, the heat dissipation fan can be rotatably fixedly connected to the base, so that during use, the direction in which the heat dissipation fan blows toward the base can be adjusted to achieve better effects.

[0076] The other components and operations of the wireless charging device 100 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here. In the description of the present invention, "first feature" and "second feature" may include one or more of these features. The vertical, horizontal, and front-to-back directions are based on the vertical, horizontal, and front-to-back directions shown in the figure.

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is at a higher level than the second feature.
