[0030] At present, more and more vehicles are equipped with wireless charging devices to improve the comfort and convenience of vehicle use. When the in-vehicle wireless charger charges mobile phones and other electronic devices, part of the energy will be converted into heat. Therefore, when charging at high power, it is necessary to add heat dissipation components to dissipate heat for the mobile phone.

[0031] In most wireless chargers, heat dissipation holes are often set directly below the charging plate. However, such a setting allows small dust particles and other impurities in the air to easily enter the interior of the charger, causing the surface of the electronic equipment inside the shell to absorb a large amount of dust, thereby affecting the normal use of the wireless charger.

[0032] In view of this, the utility model provides a wireless charging device.

[0033] Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, the wireless charging device includes a device body 100 , a supporting component 200 and a heat dissipation component 300 .

[0034] The device body 100 is used to charge the device to be charged. The device body 100 includes a shell 110, an air flow channel 140 is formed in the shell 110, an air outlet 121 is provided on the side wall of the shell 110, and an air inlet 131 is also provided on the shell 110. The air outlet 121 and the air inlet 131 are connected through the air flow channel 140; the supporting component 200 includes a bracket 210 and an elastic member 220. The bracket 210 is used to support the device to be charged, and the bracket 210 is connected to the device body 100 through the elastic member 220; the heat dissipation component 300 is connected to the device body 100 and corresponds to the air inlet 131. Among them, the bracket 210 is unloaded or supports the device to be charged, so that the elastic member 220 is released or compressed, so that the air outlet 121 is blocked or exposed by the bracket 210.

[0035] Specifically, when the wireless charging device is used to charge the device to be charged, the device to be charged only needs to be placed on the bracket 210 of the wireless charging device, thereby eliminating the need for a data cable connection between the device to be charged and the charger, thereby improving the convenience of the charging operation. Generally, the device to be charged can be an electronic device such as a tablet, a mobile phone, etc.

[0036] The device body 100 includes a shell 110, which is surrounded by a receiving cavity, and a charging coil is arranged in the receiving cavity, and the charging coil is used to charge the device to be charged. A cavity is arranged in the shell 110 of the device body 100 to form an air flow channel 140. An air outlet 121 is provided on the side wall of the shell 110, and an air inlet 131 is also provided on the shell 110. The air outlet 121 and the air inlet 131 are connected through the air flow channel 140, so that air or cooling gas flows into the air flow channel 140 through the air inlet 131 and then flows out through the air outlet 121.

[0037] The supporting assembly 200 includes a bracket 210 and an elastic member 220. The bracket 210 is used to support the device to be charged. One end of the elastic member 220 is connected to the bracket 210, and the other end is connected to the device body 100, so that the bracket 210 is connected to the device body 100 through the elastic member 220. After the supporting assembly 200 is connected to the device body 100, the supporting assembly 200 is located in the accommodating cavity of the shell 110 and above the charging coil. The bracket 210 contacts the side wall of the shell 110, and enables the bracket 210 to move up and down relative to the side wall of the shell 110 under the action of external force.

[0038] The heat dissipation assembly 300 is connected to the device body 100 and corresponds to the air inlet 131. In one embodiment, the heat dissipation assembly 300 uses a heat dissipation fan and the heat dissipation fan corresponds to the air inlet 131, so that the cooling air blown by the heat dissipation fan flows into the air flow channel 140 through the air inlet 131.

[0039] When the bracket 210 is unloaded, that is, no device to be charged is placed on the bracket 210, and no external pressure is applied to the bracket 210, the elastic member 220 is in a naturally stretched state, and the elastic member 220 is released. An air outlet 121 is provided on the side wall of the housing 110, and the bracket 210 has the highest height at this time. The bracket 210 corresponds exactly to the air outlet 121 on the side wall of the housing 110, and the air outlet 121 is blocked so that the cooling air in the air flow channel 140 does not flow out from the air outlet 121.

[0040] When the bracket 210 supports the device to be charged, that is, the device to be charged needs to be charged at this time, after the device to be charged is placed on the bracket 210, the pressure of the device to be charged causes the elastic member 220 below the bracket 210 to be compressed, thereby causing the bracket 210 to move downward, thereby exposing the air outlet 121 on the side wall of the housing 110, and allowing the cooling air in the air flow channel 140 to flow out from the air outlet 121. After flowing out from the air outlet 121, the cooling air blows toward the bracket 210 and the device to be charged, thereby cooling the electronic device being charged.

[0041] The elastic member 220 with different elastic coefficients can be selected according to the weight of the commonly used device to be charged. In one embodiment, the elastic member 220 satisfies that when the bracket 210 is unloaded, the bracket 210 just blocks the air outlet 121; when the bracket 210 supports the device to be charged, the air outlet 121 is exposed and the air outlet 121 corresponds to the upper surface of the bracket 210 and / or the lower surface of the device to be charged, so as to guide the cooling air to the charging device, so as to cool the wireless charging device and the charging device, so as to directly blow air to cool the heat source, so as to improve the cooling efficiency.

[0042] In this way, when the wireless charging device is not in use, the heat dissipation component 300 is closed, and the air outlet 121 on the side wall of the housing 110 is blocked and blocked by the bracket 210. Compared with the solution of setting the air outlet on the bracket 210 in the prior art, the utility model sets the air outlet 121 on the side wall, thereby preventing small particles of dust and other impurities from directly entering the interior of the wireless charging device, and at the same time using the bracket 210 to block, thereby further improving the dustproof effect of the wireless charging device. When the wireless charging device is used, the heat dissipation component 300 is opened, and the device to be charged is placed on the bracket 210. The elastic member 220 under the bracket 210 is compressed by force, so that the bracket 210 moves downward to expose the air outlet 121 and connect the airflow channel 140, so that the heat dissipation component 300 dissipates heat to the electronic device and the wireless charging device through the airflow channel 140. In this way, the convenience of heat dissipation when the wireless charging device is used and when the electronic device is charged is improved, and the normal operation of the wireless charging device is ensured.

[0043] A technical solution of the utility model is to set a device body 100, a supporting assembly 200 and a heat dissipation assembly 300 in a wireless charging device, wherein the device body 100 includes a housing 110, an air flow channel 140 is formed in the housing 110, and an air outlet 121 is provided on the side wall of the housing 110, and an air inlet 131 is also provided on the housing 110, and the air inlet 131 is connected to the air outlet 121 through the air flow channel 140. At the same time, the heat dissipation assembly 300 is connected to the device body 100 and is arranged corresponding to the air inlet 131. The supporting assembly 200 includes a bracket 210 and an elastic member 220, the bracket 210 is used to support the device to be charged, and the bracket 210 is connected to the device body 100 through the elastic member 220. When the electronic device is not charging, the bracket 210 is unloaded, the elastic member 220 is released, and the air outlet 121 is blocked by the bracket 210; when the electronic device is charging, the bracket 210 supports the device to be charged, the elastic member 220 is compressed, and the bracket 210 moves downward accordingly, and the air outlet 121 is exposed, so that the air flow channel 140 is connected, so that the heat dissipation component 300 cools the wireless charging device and the electronic device through the air flow channel 140. In this way, compared with the solution of setting the air outlet on the bracket 210 in the prior art, the utility model sets the air outlet 121 on the side wall, thereby preventing small particles of dust and other impurities from directly falling into the interior of the wireless charging device through the bracket 210; at the same time, the bracket 210 is used for blocking, thereby further improving the dustproof effect of the wireless charging device. When using the wireless charging device, the device to be charged only needs to be placed on the bracket 210 to cool the wireless charging device and the device to be charged, thereby improving the convenience of heat dissipation when the wireless charging device is in use and when the electronic device is charged, and ensuring the normal operation of the wireless charging device.

[0044] Furthermore, the housing 110 includes an inner shell 120 and an outer shell 130 , an air flow channel 140 is formed between the inner shell 120 and the outer shell 130 , an air outlet 121 is provided on the side wall of the inner shell 120 , and an air inlet 131 is provided on the bottom wall of the outer shell 130 .

[0045] Specifically, the housing 110 includes an inner shell 120 and an outer shell 130, and an air flow channel 140 is formed between the inner shell 120 and the outer shell 130. The inner shell 120 is surrounded to form a receiving cavity, and a charging coil and a supporting assembly 200 are arranged in the receiving cavity. In the scheme shown in the drawings of the utility model, the air outlet 121 is arranged on the side wall of the inner shell 120, and the air inlet 131 is arranged on the bottom wall of the outer shell 130. At the same time, the heat dissipation assembly 300 is arranged at the bottom wall of the device body 100 to correspond to the air inlet 131. Thereby, the cooling wind of the heat dissipation assembly 300 enters the air flow channel 140 through the air inlet 131, and then blows toward the wireless charging device and the device to be charged through the air outlet 121. In this way, the air outlet 121 is arranged at the bottom wall of the outer shell 130, and correspondingly, the heat dissipation component 300 is arranged below the device body 100, thereby avoiding interference between the heat dissipation component 300 and other components such as the charging coil in the device body 100, which is also beneficial to the overall aesthetics and neatness of the wireless charging device.

[0046] Furthermore, a plurality of protrusions 211 are provided on the bracket 210 , and the plurality of protrusions 211 are used to abut against the device to be charged, and a heat dissipation channel is formed between the air outlet 121 and the plurality of protrusions 211 .

[0047] Specifically, a plurality of protrusions 211 are provided on the bracket 210. When the device to be charged is placed on the bracket 210, the device to be charged abuts against the protrusions 211. The elastic member 220 is compressed, the bracket 210 moves downward, and the air outlet 121 is exposed. A heat dissipation channel is formed between the air outlet 121 and the plurality of protrusions 211, and the cooling wind flowing out of the air outlet 121 flows into the heat dissipation channel, thereby cooling the device to be charged and the wireless charging device, thereby further improving the cooling efficiency of the wireless charging device during charging. In one embodiment, after the device to be charged is placed on the bracket 210, the bracket 210 moves downward until the plurality of protrusions 211 on the bracket 210 just correspond to the air outlet 121, so that the cooling wind is directly blown into the heat dissipation channel, which is beneficial to improving the cooling efficiency.

[0048] Furthermore, a plurality of elastic members 220 are provided, and the plurality of elastic members 220 are spaced apart from each other on a side of the bracket 210 facing the device body 100 .

[0049] Specifically, a plurality of elastic members 220 may be provided, thereby improving the stability and reliability of the support of the bracket 210 by the elastic members 220, and also facilitating the stability of the bracket 210 moving up and down. The plurality of elastic members 220 are arranged at intervals on a side of the bracket 210 facing the device body 100. In one embodiment, four elastic members 220 are provided, and the four elastic members 220 are respectively located around the bracket 210. Of course, the number of the elastic members 220 may also be two or three or other numbers.

[0050] Furthermore, the elastic member 220 is a spring.

[0051] Specifically, in one embodiment, the elastic member 220 is a spring. Of course, the elastic member 220 can also be an elastic sheet or the like.

[0052] Furthermore, the supporting assembly 200 is provided in multiple groups.

[0053] Specifically, in one embodiment, the supporting assembly 200 is provided in multiple groups, so that multiple devices to be charged can be charged simultaneously, thereby meeting the simultaneous charging needs of multiple electronic devices.

[0054] Furthermore, along the height direction of the device body 100 , multiple groups of supporting components 200 are located in the same plane, and the multiple groups of supporting components 200 are arranged in parallel. There are multiple air outlets 121 , and one supporting component 200 corresponds to one air outlet 121 .

[0055] Specifically, the device body 100 has a certain height, and along the height direction of the device body 100, multiple groups of supporting components 200 are located on the same plane. That is, in the height direction of the device body 100, the supporting components 200 also have a certain height, and the heights of the multiple groups of supporting components 200 are consistent. At the same time, the multiple groups of supporting components 200 are arranged in parallel, that is, the multiple groups of supporting components 200 are all connected to the device body 100, and at the same height, the multiple groups of supporting components 200 are arranged in a "one" shape. Correspondingly, a plurality of air outlets 121 are also provided on the device body 100, and a group of supporting components 200 is provided corresponding to one air outlet 121. One group of supporting components 200 has a bracket 210, and the device body 100 is provided with a charging coil correspondingly below the bracket 210, which can charge one device to be charged; multiple groups of supporting components 200 have multiple brackets 210, and the device body 100 is provided with multiple charging coils correspondingly below the multiple brackets 210, which can charge multiple devices to be charged.

[0056] In this way, when a group or part of the supporting components 200 is needed for charging, the corresponding number of devices to be charged are placed on the brackets 210 of the corresponding group of supporting components 200. Correspondingly, the air outlets 121 corresponding to the group of supporting components 200 are exposed to cool and dissipate the heat of the devices to be charged. The corresponding air outlets 121 of the unused supporting components 200 are blocked by the brackets 210 so that the cooling air does not flow out.

[0057] In one embodiment, the wireless charging device includes two groups of supporting components 200. When a device to be charged is charged, the corresponding air outlet 121 of the device to be charged is exposed to cool and dissipate heat to the device to be charged. If there is no device to be charged on the other supporting component 200, its air outlet 121 is blocked by its bracket 210, so that cooling air does not flow out from the air outlet 121. In this way, compared with the setting in which all air outlets 121 are fully exposed, the air outlet 121 in the utility model adopts a setting in which it is exposed when in use and blocked when not in use, so that the cooling air only flows to the supporting component 200 in use, and only cools and dissipates heat to the device to be charged there, thereby improving the heat dissipation efficiency. Of course, in other embodiments, the supporting component 200 can also be set to three groups or other numbers.

[0058] In one embodiment, one heat dissipation assembly 300 is provided, and correspondingly, one air inlet 131 is also provided. At this time, the supporting assembly 200 is provided with multiple groups, and correspondingly, multiple air outlets 121 are provided. One air inlet 131 is connected to multiple air outlets 121 respectively through the airflow channel 140. In one embodiment, the speed of the heat dissipation fan can also be adjusted according to the charging power. When only one electronic device is charged, its corresponding charging coil is turned on, and the speed of the heat dissipation fan is adjusted according to the charging power. When multiple electronic devices are charged at the same time, the speed of the heat dissipation fan needs to be adjusted according to the larger charging power. It is worth noting that the heat dissipation fan is electrically connected to the controller, and the controller adjusts the speed of the heat dissipation fan according to the charging power. This belongs to the prior art, and the connection relationship and control logic between the heat dissipation fan and the controller are not repeated here.

[0059] In one embodiment, a plurality of heat dissipation components 300 may be provided, that is, one heat dissipation component 300 is provided for each supporting component 200, so that one heat dissipation component 300 can provide cooling air to one air outlet 121. In this way, the cooling effect is improved, but the cost is higher.

[0060] Furthermore, the multiple air outlets 121 are located on the same side wall of the housing 110 .

[0061] Specifically, the plurality of air outlets 121 are located on the same side wall of the housing 110. In one embodiment, the plurality of air outlets 121 are all located on the left side wall of the housing 110, so that the cooling air flowing out of the plurality of air outlets 121 flows from the left side to the right side, thereby ensuring the consistency of the flow direction of the cooling air, thereby avoiding the noise caused by the cooling air flowing out of the plurality of air outlets 121 due to different flow directions, so as to improve the comfort of use of the wireless charging device.

[0062] Furthermore, an object detection device is provided in the bracket 210, and the object detection device is used to detect whether the bracket 210 supports the device to be charged.

[0063] Specifically, an object detection device can be provided in the bracket 210 to detect whether a device to be charged is placed on the bracket 210. In one embodiment, the object detection device is electrically connected to the controller. When it is detected that a device to be charged is placed on the bracket 210, the controller controls the corresponding charging coil to open to start charging. It is worth noting that the electrical connection between the controller and the object detection device is a prior art and will not be described in detail here. In one embodiment, the object detection device is a sensor, which can be a height sensor, a pressure sensor, a proximity sensor, a laser sensor, and the like.

[0064] The utility model also proposes a vehicle, which includes a wireless charging device. The specific structure of the wireless charging device refers to the above-mentioned embodiment. Since the vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0065] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention.
