Description

Technical Field

[0001] This application relates to the field of wireless charging technology, and in particular to a wireless charging heat dissipation device. Background Technology

[0002] The basic principle of wireless charging can be summarized as the conversion of electrical energy into a magnetic field, which is then transmitted through the air and converted back into electrical energy. Specifically, wireless charging devices mainly consist of an energy transmitter and an energy receiver. The transmitter converts electrical energy into high-frequency alternating current (AC) through a power source, generating an alternating magnetic or electric field. The receiver couples with the transmitter's magnetic or electric field to convert the energy into direct current (DC), providing power to the load. Existing charging devices, which use the received energy to charge batteries, are typically placed directly on a table, resulting in poor heat dissipation. The internal electronic components gradually heat up, and this high-temperature environment can lead to decreased charging performance and, in severe cases, safety hazards. Utility Model Content

[0029] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0031] The wireless charging heat dissipation device will be described in detail below through specific embodiments:

[0032] Reference Figures 1 to 3As shown in the figure, some embodiments of this application provide a wireless charging heat dissipation device, including a base 1, a mounting bracket 2, and a support member 3.

[0033] The mounting bracket 2 is rotatably connected to the base 1, and the support member 3 is supported between the mounting bracket 2 and the base 1. The support member 3 can ensure the stability of the mounting bracket 2 relative to the base 1, and at the same time prevent the mounting bracket 2 from contacting the base 1, thus ensuring the heat dissipation area. A heat dissipation space is formed between the mounting bracket 2 and the base 1 to promote air circulation.

[0034] Specifically, the mounting bracket 2 has a limiting space for positioning the wireless charging device 0. A charging position is formed on the side of the mounting bracket 2 away from the base 1, and the charging position corresponds to the limiting space. The mobile device can be charged when placed on the charging position. At this time, the wireless charging device 0 is confined inside the mounting bracket 2, avoiding contact with the base 1 and the tabletop, thus ensuring effective heat dissipation of the wireless charging device 0 and preventing overheating. By providing sufficient heat dissipation space, safety hazards can be reduced and the user experience improved.

[0035] It should be noted that when no wireless charging device 0 is provided between the first mounting bracket 21 and the second mounting bracket 22, the first mounting bracket 21 and the second mounting bracket 22 can also be used as a stand after assembly, so as to have a high heat dissipation effect when mobile devices such as mobile phones are operating.

[0036] In some embodiments, the mounting bracket 2 includes a first mounting bracket 21 and a second mounting bracket 22. The first mounting bracket 21 is rotatably connected to the base 1, and the second mounting bracket 22 is connected to the first mounting bracket 21. A limiting space is formed between the second mounting bracket 22 and the first mounting bracket 21. A charging position is formed on the side of the second mounting bracket 22 away from the first mounting bracket 21 for charging the mobile device.

[0037] The second mounting bracket 22 is detachably mounted on the first mounting bracket 21. That is, when the second mounting bracket 22 is mounted on the first mounting bracket 21, the wireless charging device 0 can be confined within the limiting space between the first mounting bracket 21 and the second mounting bracket 22, and the wireless charging device 0 can maintain a stable position. When the second mounting bracket 22 is removed from the first mounting bracket 21, the wireless charging device 0 can be removed from the limiting space, so as to facilitate the replacement and maintenance of the wireless charging device 0.

[0038] If the size of the wireless charging device 0 changes, a second mounting bracket 22 of a different size can be replaced to match the first mounting bracket 21, thus adapting to different wireless charging devices 0 and achieving high versatility.

[0039] In practice, one of the first mounting bracket 21 and the second mounting bracket 22 is provided with a locking block 221, and the other is provided with a locking groove 211. The locking groove 211 engages with the locking block 221, thus enabling a detachable connection between the first mounting bracket 21 and the second mounting bracket 22. During installation, the locking block 221 on the second mounting bracket 22 is aligned with the locking groove 211 on the first mounting bracket 21. After pressing down, the locking block 221 engages with the locking groove 211. The friction between the locking block 221 and the groove wall of the locking groove 211 secures the connection between the first mounting bracket 21 and the second mounting bracket 22. During disassembly, lifting the second mounting bracket 22 upwards will disengage the locking block 221 from the locking groove 211.

[0040] Specifically, the height of the card block 221 exceeds the depth of the card slot 211. When the card block 221 is inserted into the card slot 211, the card block 221, which is higher than the card slot 211, is limited between the first mounting bracket 21 and the second mounting bracket 22. In this way, the card block 221, together with the first mounting bracket 21 and the second mounting bracket 22, can form a limiting space. That is, after the card is engaged, the second mounting bracket 22 does not shake, and the size of the limiting space is fixed, thereby limiting the wireless charging device 0 within the limiting space.

[0041] Of course, the second mounting bracket 22 and the first mounting bracket 21 can also be connected in other ways, such as snap-fit ​​or magnetic connection. This application does not limit this. Specifically, magnets can be embedded in the first mounting bracket 21 and the second mounting bracket 22 respectively to ensure connection. Alternatively, a barb structure can be provided on the snap block 221 to be inserted into the snap slot 211 to lock the first mounting bracket 21 and the second mounting bracket 22.

[0042] For example, refer to Figure 1 As shown, the second mounting bracket 22 is provided with a locking block 221, which is arranged around the circumference of the second mounting bracket 22. The first mounting bracket 21 is provided with a slot 211, which is arranged around the circumference of the first mounting bracket 21. The shapes of the locking block 221 and the slot 211 are adapted to achieve plug-in engagement and connect the first mounting bracket 21 and the second mounting bracket 22. In this arrangement, the surrounding locking block 221 can distribute the load and prevent the first mounting bracket 21 and the second mounting bracket 22 from deforming due to the excessive weight of the wireless charging device 0.

[0043] Of course, the card block 221 can also be a protruding structure of fixed length, and multiple card blocks 221 are provided. Multiple card blocks 221 are arranged at intervals, and the card slots 211 are set to correspond to the protruding structures so as to insert them one by one and realize the connection between the first mounting bracket 21 and the second mounting bracket 22.

[0044] In some embodiments, the first mounting bracket 21 is rotatably connected to the base 1, one end of the support member 3 is rotatably connected to the side of the first mounting bracket 21 facing the base 1, the top surface of the base 1 facing the first mounting bracket 21 is provided with a plurality of snap-fit ​​slots 11, and the other end of the support member 3 is replaceably inserted into one of the snap-fit ​​slots 11.

[0045] It is understandable that when the support 3 is supported in the slot 11 on the base 1, the first mounting bracket 21, the base 1 and the support 3 can form a triangular support structure, and the second mounting bracket 22 and the wireless charging device 0 are installed on the first mounting bracket 21, which has high stability.

[0046] It should be noted that the extension direction of the snap-fit ​​groove 11 is parallel to the rotation center line of the first mounting bracket 21 and is arranged radially at intervals. Thus, when the other end of the support member 3 is inserted into different snap-fit ​​grooves 11, the first mounting bracket 21 and the base 1 have different angles. In this way, when the heat dissipation device is used as a bracket, it can adapt to different viewing angle changes and improve the user experience.

[0047] Of course, in other embodiments, the support member 3 can also be rotatably connected to the base 1. Correspondingly, multiple snap-fit ​​slots 11 are opened on the side of the first mounting bracket 21 facing the base 1, which has the same effect, ensuring structural stability while achieving angle adjustment.

[0048] Reference Figure 3 As shown, the snap-fit ​​groove 11 has an arc-shaped chamfer on the side facing the rotation center of the first mounting bracket 21, that is, it smoothly transitions from the side of the groove opening facing the rotation center of the first mounting bracket 21 to the bottom of the groove, reducing friction and facilitating insertion. At the same time, it can also prevent the support member 3 from being worn on the side facing the arc-shaped chamfer, thus extending its service life.

[0049] In practice, the curved chamfer can guide the support 3 to slide into the snap-fit ​​groove 11, reducing resistance. When pulling it out, it can also avoid jamming, enabling quick adjustment and reducing component wear.

[0050] In some embodiments, the first mounting bracket 21 has two connecting blocks 212 on the side facing the base 1. The connecting blocks 212 are positioned away from the airbag 26, and a rotating shaft is provided between the two connecting blocks 212. One end of the support member 3 is formed as a sleeve end 31, which is sleeved on the rotating shaft to ensure stable rotation. The sleeve end 31 and the rotating shaft are rotatably engaged to drive the support member 3 to rotate relative to the first mounting bracket 21, thereby adapting to different angles of the first mounting bracket 21 relative to the base 1. The rotating shaft can be rotatably connected to the connecting blocks 212 to further reduce rotational resistance.

[0051] It is understandable that the sleeve design at the end of the support member 3 can reduce the friction between the support member 3 and the first mounting bracket 21 and avoid jamming. The end of the support member 3 away from the sleeve end 31 is inserted into the snap-fit ​​groove 11.

[0052] In some embodiments, refer to Figure 1 and Figure 2 As shown, the base 1 has two connecting rods 12 at its end, and each connecting rod 12 has a rotating post 13 on its opposite side. The mounting bracket 2 (specifically the first mounting bracket 21) has mating holes 23 on its opposite sides. The rotating post 13 is inserted into the mating hole 23 and rotates in conjunction with the mating hole 23. That is, the rotating post 13 can serve as the rotation center of the first mounting bracket 21 relative to the base 1, meaning that the first mounting bracket 21 can rotate around the rotating post 13 as its axis, thereby achieving angle adjustment of the first mounting bracket 21.

[0053] By setting two sets of connecting rods 12 and rotating columns 13, stable support can be provided for the first mounting frame 21, avoiding vibration and ensuring the overall rigidity of the structure.

[0054] In practice, the connecting rod 12 is formed as a slightly deformable structure. By moving the connecting rod 12, the rotating post 13 can be inserted into the mating hole 23. Alternatively, the rotating post 13 can be pulled out of the mating hole 23 to achieve disassembly. The disassembly and assembly are simple and easy to replace parts.

[0055] In some embodiments, the first mounting bracket 21 is formed as a grid-like frame structure, which can reduce the contact area with the wireless charging device 0. The first mounting bracket 21 has heat dissipation grooves, meaning the open areas on the grid-like frame structure can be formed as heat dissipation grooves to accelerate airflow and improve heat dissipation. The first mounting bracket 21 is formed as a rectangular frame.

[0056] The second mounting bracket 22 is formed as a grid-like frame structure, which reduces the contact area with the wireless charging device 0. The second mounting bracket 22 has clearance grooves 222, meaning the open areas on the grid-like frame structure can form clearance grooves 222. This not only accelerates airflow and improves heat dissipation, but also exposes the wireless charging device 0, allowing it to contact the mobile device for charging. The second mounting bracket 22 is formed as a rectangular frame.

[0057] This configuration allows a large area of ​​the wireless charging device 0 to be exposed outside the first mounting bracket 21 and the second mounting bracket 22, thereby improving the heat dissipation efficiency of the wireless charging device 0.

[0058] In some embodiments, an anti-slip pad 24 is provided on the side of the mounting bracket 2 away from the base 1 (specifically, on the side of the second mounting bracket 22 away from the first mounting bracket 21). When the mobile device is placed, its back side contacts the anti-slip pad 24 to improve adhesion to the mobile device, thereby increasing friction and preventing the mobile device from sliding, allowing for continuous charging. Specifically, the anti-slip pad 24 is located on the top surface of the second mounting bracket 22, i.e., on the side of the second mounting bracket 22 away from the first mounting bracket 21. The material can be silicone, and by providing textured protrusions on the surface, friction can be further increased to ensure the stability of the mobile device during charging.

[0059] Reference Figure 1 As shown, there are two anti-slip pads 24, which are respectively placed on both sides of the clearance groove 222 to ensure that the mobile device is subjected to balanced force and avoids displacement.

[0060] In some embodiments, the mounting bracket 2 is further provided with a support plate 25. Specifically, the support plate 25 is provided at the end of the second mounting bracket 22 near the rotation center of the second mounting bracket 22, and the support plate 25 extends in a direction away from the surface of the second mounting bracket 22 to support the bottom of the mobile device and prevent the mobile device being charged from falling off when the second mounting bracket 22 is set at an angle to the base 1.

[0061] Specifically, the end of the support plate 25 away from the second mounting bracket 22 is also provided with an anti-detachment protrusion to further increase the limiting ability of the mobile device and prevent it from falling.

[0062] In some embodiments, an airbag 26 is provided on the first mounting bracket 21. The airbag 26 is filled with a cooling medium. By forming a heat dissipation space between the first mounting bracket 21 and the base 1, the airbag 26 also has sufficient installation space, thereby ensuring the heat dissipation effect of the airbag 26.

[0063] In practice, when the wireless charging device 0 is confined within the restricted space, the airbag 26 can directly contact the wireless charging device 0 to directly absorb the heat generated on the wireless charging device 0, or it can absorb the heat generated on the wireless charging device 0 at intervals through the first mounting bracket 21. The cooling medium in the airbag 26 can be water, and the airbag 26 has openings to facilitate the injection and discharge of the cooling medium.

[0064] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0065] The above are merely specific embodiments of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to these embodiments, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
