Description

Technical Field

[0001] This utility model belongs to the field of charging technology, and specifically relates to a charging device with a heat dissipation structure. Background Technology

[0002] A charging device is a device used to charge electronic devices, such as mobile phones, headphones, and tablets. During the charging process, the charging device generates heat, causing both the charging device and the electronic device to overheat. If heat dissipation is not timely, the charging device and the electronic device will become too hot, which will not only affect the lifespan of the charging device and the electronic device, but also pose a certain danger.

[0003] In particular, if the magnetic charging device fails to dissipate heat in time during the charging process, the accumulated heat can cause the magnetic charging device to lose its magnetism, thus preventing it from charging electronic devices properly. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a charging device with a heat dissipation structure. Air is introduced into the second channel from the air inlet and the first channel by the air supply component, and the air is discharged from the air outlet. Since the second channel is arranged along the outer contour of the charging position, most of the heat generated by the charging structure can be carried away during the air flow in the airflow channel. Furthermore, since the air outlet is arranged close to the outer contour of the charging position, the air can further carry away the heat of the electronic device placed on the charging position during the process of being discharged from the air outlet.

Furthermore, since the air outlet is arranged close to the outer contour of the charging position, the air can further carry away the heat from the electronic device being charged on the charging position as it is discharged from the air outlet. The heat dissipation effect of this heat dissipation structure is good. Attached Figure Description

[0046] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0047] See Figures 1 to 9This utility model discloses a charging device with a heat dissipation structure, comprising: a housing 10, on which a charging position 101 is provided; a charging structure 30, which is disposed inside the housing 10 and corresponds to the charging position 101; and a heat dissipation structure 40, which includes an air supply component 401 and an airflow main channel 402, which is disposed inside the housing 10 and on the housing 10 are an air inlet 102 and an air outlet 103; the airflow main channel 402 includes a first channel 4021 and a second channel 4022, the air inlet 102, the first channel 4021, the second channel 4022 and the air outlet 103 are sequentially connected, the air supply component 401 is disposed between the first channel 4021 and the air inlet 102, the second channel 4022 is disposed along the outer contour of the charging position 101, and the air outlet 103 is disposed close to the outer contour of the charging position 101.

[0048] This utility model is provided with a heat dissipation structure 40. Air is introduced into the second channel 4022 from the air inlet 102 and the first channel 4021 by the air supply component 401, and the air is discharged from the air outlet 103. Since the second channel 4022 is arranged along the outer contour of the charging position 101, most of the heat generated by the charging structure 30 can be carried away during the air flow in the airflow channel 402. Furthermore, since the air outlet 103 is close to the outer contour of the charging position 101, the air can further carry away the heat from the electronic device 80 being charged on the charging position 101 during the process of being discharged from the air outlet 103. The heat dissipation effect of this heat dissipation structure 40 is good.

[0049] This utility model is applicable to scenarios such as vehicle and home use, but its specific application scenarios are not limited.

[0050] In this embodiment of the present invention, the first channel 4021 includes a first connecting section 40211 and a first guiding section 40212 that are interconnected. The first connecting section 40211 is connected to the second channel 4022 through the first guiding section 40212. The first connecting section 40211 is arc-shaped and is arranged along the outer contour of the air supply component 401. The first guiding section 40212 is inclined towards the air outlet 103.

[0051] For example, see Figure 5 The air supply component 401 draws air from outside the housing 10 into the first channel 4021 and the second channel 4022 from the air inlet 102 and discharges it from the air outlet 103 to form a heat dissipation airflow.

[0052] Since the first guide section 40212 is inclined towards the air outlet 103, after the air enters the first guide section 40212 through the first connecting section 40211, the first guide section 40212 can guide the airflow towards the air outlet 103 to facilitate heat dissipation.

[0053] For example, see Figure 1 as well as Figure 2 The air inlet 102 is located at the bottom of the housing 10, and the air outlet 103 is located at the top of the housing 10, so that the first guide section 40212 can guide the airflow upward.

[0054] In this embodiment of the present invention, the housing 10 is provided with at least two air outlets 103; the second channel 4022 includes a second connecting section 40221, a second guiding section 40222, a third guiding section 40223, and a fourth guiding section 40224 that are interconnected. The second connecting section 40221 is arc-shaped. The second guiding section 40222 is disposed at the first end of the second connecting section 40221, the third guiding section 40223 is disposed at the second end of the second connecting section 40221, and the fourth guiding section 40224 is disposed between the second guiding section 40222 and the third guiding section 40223; the fourth guiding section 40224 is connected to at least one of the air outlets 103, and the middle part of the second connecting section 40221 is connected to at least another air outlet 103; the first channel 4021 introduces airflow into at least one of the second guiding section 40222, the third guiding section 40223, or the fourth guiding section 40224.

[0055] For example, see Figure 5 When the air supply component 401 supplies air by rotating clockwise, the airflow forms a clockwise rotating airflow in the first channel 4021. When the clockwise rotating airflow enters the second channel 4022, part of the rotating airflow can enter the second connecting section 40221 through the second guide section 40222. When this part of the rotating airflow passes through the air outlet 103 located in the middle of the second connecting section 40221, it carries away some of the heat generated by the charging structure 30. Part of the rotating airflow can enter the second connecting section 40221 through the third guide section 40223. When this part of the rotating airflow passes through the air outlet 103 located in the middle of the second connecting section 40221, it carries away some of the heat generated by the charging structure 30. Part of the rotating airflow passes through the fourth guide section 40224 and is discharged from the corresponding air outlet 103, carrying away some of the heat generated by the charging structure 30, thereby achieving relatively rapid heat dissipation.

[0056] In this embodiment of the present invention, the second guide segment 40222 is inclined, and the middle part of the second connecting segment 40221 is at a higher height than the first end of the second connecting segment 40221; the third guide segment 40223 is inclined, and the middle part of the second connecting segment 40221 is at a higher height than the second end of the second connecting segment 40221.

[0057] For example, see Figure 5 as well as Figure 6 Because there is a height difference between different positions of the second channel 4022, the position of the second channel 4022 closer to the first channel 4021 is relatively low, and the position of the second channel 4022 further away from the first channel 4021 is relatively high. Therefore, the second channel 4022 covers a larger range in the longitudinal direction. In other words, the second channel 4022 covers a larger range in the thickness or height direction of the housing 10. As a result, the range of heat exchange between the airflow and the charging structure 30 is larger, and the heat dissipation effect of the heat dissipation structure 40 is better.

[0058] In this embodiment of the utility model, a first partition 50 is provided inside the housing 10, and an air supply component 401 is eccentrically disposed inside the first partition 50 to form a first connecting section 40211. The first partition 50 has a guide portion 501 for forming a first guide section 40212.

[0059] For example, see Figure 6 By setting the first separator 50, it is beneficial to form the first channel 4021, realize the split molding, and thus reduce the production cost of the charging device with heat dissipation structure.

[0060] Furthermore, the air supply component 401 is eccentrically positioned inside the first partition 50 to form the first connecting section 40211. When the air supply component 401 rotates clockwise, it can form a clockwise rotating airflow. When the air supply component 401 rotates counterclockwise, it can form a counterclockwise rotating airflow, thereby providing directional airflow to the second channel 4022, which is beneficial for heat dissipation.

[0061] In this embodiment of the present invention, a second partition 60 is provided inside the housing 10. The second partition 60 has a sleeve structure 601 extending in the direction of the air outlet 103. The sleeve structure 601 has a mounting hole 602 for mounting the charging structure 30 inside. The mounting hole 602 is correspondingly provided with the charging position 101. The sleeve structure 601 has an annular recess 603 on the outside. The annular recess 603 is used to form a second channel 4022.

[0062] For example, see Figure 5 as well as Figure 6By setting the second separator 60, it is beneficial to form the second channel 4022, realize the split molding, and thus reduce the production cost of the charging device with heat dissipation structure.

[0063] Furthermore, the sleeve structure 601 separates the charging structure 30 from the airflow channel, preventing the airflow from affecting the charging structure 30. The second channel 4022 can be arranged around the charging structure 30, and the heat dissipation structure 40 has a large heat exchange area, thereby achieving a better heat dissipation effect.

[0064] In this embodiment of the present invention, the charging structure 30 includes a control circuit module 301, a magnetic coil 302, a magnetic ring 303, and a mounting bracket 304. The control circuit module 301 is electrically connected to the magnetic coil 302. The magnetic ring 303 is disposed outside the magnetic coil 302, and both the magnetic coil 302 and the magnetic ring 303 are disposed on the mounting bracket 304. The sleeve structure 601 is provided with a third partition 70 inside. The third partition 70 divides the mounting hole 602 into a first mounting cavity 6021 and a second mounting cavity 6022 that are interconnected. The magnetic coil 302, the magnetic ring 303, and the mounting bracket 304 are all disposed in the first mounting cavity 6021, and the control circuit module 301 is disposed in the second mounting cavity 6022.

[0065] It should be noted that how to use the charging structure 30 to achieve charging is existing technology and will not be elaborated here.

[0066] For example, see Figure 6 The circuit that electrically connects the control circuit module 301 and the magnetic coil 302 can be connected to each other through the first mounting cavity 6021 and the second mounting cavity 6022; the mounting hole 602 is separated by the third separator 70, making the internal space layout of the mounting hole 602 more reasonable.

[0067] Furthermore, the first sidewall 6031 of the annular recess 603 is located close to the first mounting cavity 6021, and the second sidewall 6032 of the annular recess 603 is located close to the second mounting cavity 6022. Thus, when the airflow flows in the second channel 4022, it can carry away the heat generated by the magnetic coil 302 and the magnetic ring 303 during operation, as well as the heat generated by the control circuit module 301 during operation, which is beneficial for heat dissipation of the charging structure 30.

[0068] In this embodiment of the utility model, the mounting bracket 304 includes a mounting platform 3041 and a support foot 3042. The support foot 3042 is disposed below the mounting platform 3041 and is supported on the third partition 70.

[0069] For example, see Figure 7 as well as Figure 8The support foot 3042 is inserted into the third partition 70 to realize the installation of the mounting bracket 304 and the third partition 70.

[0070] Since the mounting bracket 304 has support feet 3042, the mounting bracket 304 as a whole is a support structure. There is a heat dissipation gap between the mounting bracket 304 and the third partition 70, which can avoid the problem of heat accumulation caused by the magnetic coil 302, magnetic ring 303 and control circuit module 301 being tightly attached.

[0071] In this embodiment of the present invention, the housing 10 has an outwardly protruding protrusion 104 at the charging position 101, and the air outlet 103 and the charging position 101 have a height difference H in the height direction of the protrusion 104, where H > 0.

[0072] For example, see Figure 6 as well as Figure 9 When the electronic device 80 is placed on the protrusion 104 for charging, there is a height difference between the vent 103 and the electronic device 80. In other words, the electronic device 80 will not affect the exhaust of the vent 103. There is an exhaust gap between the vent 103 and the electronic device 80. When the airflow is discharged from the vent 103, it flows through the bottom of the electronic device 80 and can carry away the heat on the electronic device 80, thereby dissipating heat from the electronic device 80.

[0073] Furthermore, there is a heat dissipation gap between the electronic device 80 and the rest of the housing 10. That is to say, the electronic device 80, except for the part corresponding to the charging position 101, does not come into contact with the charging device with the heat dissipation structure, which further facilitates the heat dissipation of the electronic device 80.

[0074] In this embodiment of the utility model, the air supply component 401 includes an impeller 4011.

[0075] For example, see Figure 5 Impeller 4011 is a centrifugal impeller. Impeller 4011 can be driven to rotate by a motor. During the rotation of impeller 4011, air outside the housing 10 is drawn from the air inlet 102 into the first channel 4021 and the second channel 4022 and discharged from the air outlet 103 to form a heat dissipation airflow.

[0076] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
