Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging equipment, in particular to a wireless charger structure with a foreign matter discharge function. Background Art

[0002] At present, due to travel needs, more and more cars are equipped with high-power wireless chargers. When the mobile phone is continuously charged at high power, the mobile phone will become hot, resulting in excessive temperature, which limits the charging power and reduces the charging rate. Therefore, in order to dissipate heat for the mobile phone, the wireless charger is equipped with a radiator (such as a fan) inside. The wind blown by the radiator is blown out from the air outlet of the interior panel through the air duct to dissipate heat for the mobile phone. Wireless chargers are often arranged around the armrest box. Users are accustomed to placing debris on the panel above the wireless charger. Foreign objects (such as rice crust, stones, etc.) are easy to fall into the radiator from the air outlet, causing abnormal working conditions such as radiator jamming and abnormal noise, and even damaging the radiator, affecting the user's experience. If an opening connected to the air outlet is directly opened at the bottom of the wireless charger to allow foreign objects to fall out, the wind blown out by the radiator can easily leak out from the opening, resulting in reduced heat dissipation effect of the wireless charger on the mobile phone. Utility Model Content

[0003] In view of this, in order to solve the above problems, the purpose of the utility model is to provide a wireless charger structure with a foreign matter discharge function.

[0004] A wireless charger structure with a foreign object discharge function comprises a shell, one side of the shell is provided with an air outlet, the other side of the shell is provided with a foreign object discharge port, a heat dissipation duct is provided between the air outlet and the foreign object discharge port, a heat dissipation fan is provided on the side of the heat dissipation duct close to the foreign object discharge port, a rotatable baffle is provided in the foreign object discharge port, the weights of the two sides of the baffle are different, and the baffle is rotated to block and open the foreign object discharge port.

[0005] In the above technical scheme, the air outlet is arranged on the top surface of the shell, and the foreign object exhaust port is arranged on the bottom surface of the shell. When the charging device needs to be charged, it is placed on the top surface of the shell and covers the air outlet. The cavity between the air outlet and the foreign object exhaust port is a heat dissipation duct. The wind blown by the cooling fan enters the heat dissipation duct and can be blown out from the air outlet, thereby cooling the charging device; a baffle is provided in the foreign object exhaust port, and the baffle is unevenly weighted, so that the weight on both sides of the baffle is different. The baffle can rotate in the foreign object exhaust port. When the wireless charger is not working, the baffle rotates to a vertical state and remains under the action of gravity due to the different weights on both sides. At this time, the baffle does not block the foreign object exhaust port, and the foreign object exhaust port is in an open state. At this time, if there is a foreign object If the foreign matter falls into the air outlet, it will pass through the heat dissipation duct and fall out from the foreign matter exhaust port. When the charging device is placed on the top surface of the shell, the wireless charger is in working state. At this time, the heat dissipation fan is started, and the wind blown by the heat dissipation fan enters the heat dissipation duct. At this time, since the charging device is placed on the air outlet, it blocks the air outlet, so foreign matter cannot enter the wireless charger through the air outlet. At the same time, the baffle rotates under the action of wind pressure and abuts against both sides of the foreign matter exhaust port, thereby blocking the foreign matter exhaust port and closing the foreign matter exhaust port. At this time, since the foreign matter exhaust port is in a closed state, the wind blown by the heat dissipation fan will not leak out from the foreign matter exhaust port, but will be blown out from the air outlet, thereby ensuring the heat dissipation effect for the charging device placed on the air outlet.

[0006] Optionally, in a possible implementation, a rotating shaft is passed through the baffle, the baffle is rotatably connected to the rotating shaft, and the rotating shaft is installed on a side wall of the shell.

[0007] In the above technical solution, the baffle is provided with a rotating shaft, and the baffle can rotate relative to the rotating shaft. Due to the uneven weight distribution of the baffle, the two parts of the baffle with the rotating shaft as the dividing line have different weights. When the wireless charger is not working, the baffle rotates to a vertical state under the action of gravity, so that the heavier part is located at the bottom.

[0008] Optionally, in a possible implementation manner, a side of the heat dissipation air duct close to the foreign object exhaust port is provided with an inclined portion.

[0009] In the above technical solution, the side wall of the heat dissipation duct near the foreign object discharge port is an inclined surface, which facilitates foreign objects to slide to the foreign object discharge port below and be discharged without staying in the wireless charger.

[0010] Optionally, in a possible implementation manner, soft rubber pads are provided on the shell surface on both sides of the foreign object discharge port.

[0011] In the above technical solution, the baffle rotates under the action of the wind pressure generated by the cooling fan, and abuts against the shells on both sides, thereby blocking the foreign object discharge port and closing the foreign object discharge port. A soft rubber pad is provided at the contact position between the shell and the baffle for buffering, preventing the baffle from colliding with the shell and producing abnormal noise, thereby optimizing the user experience.

[0012] Optionally, in a possible implementation, the shell includes a panel, an upper cover and a base connected in sequence, the air outlet is arranged on the panel, and the upper cover is buckled and connected to the base to form a cavity.

[0013] In the above technical solution, the panel, the upper cover and the base are connected in sequence, wherein the charging device is placed on the panel when charging, and the wind blown out by the cooling fan dissipates the heat of the charging device through the air outlet on the panel. After the upper cover and the base are snap-fitted together, a cavity is formed inside for installing charging components such as PCB boards and coils.

[0014] Optionally, in a possible implementation, a heat sink is installed on a side of the base away from the upper cover, the foreign matter discharge port is arranged on the heat sink, and the heat dissipation fan is arranged in the heat sink.

[0015] In the above technical solution, the heat sink is installed at the bottom of the base, which is convenient for disassembling the heat sink and thus convenient for cleaning and maintenance of the inside of the heat sink.

[0016] Optionally, in a possible implementation manner, a blocking member is provided between the foreign object exhaust port and the heat dissipation fan.

[0017] In the above technical solution, the blocking member is used to block foreign objects from entering the wireless charger and prevent the foreign objects from contacting the cooling fan.

[0018] Optionally, in a possible implementation, the blocking member includes a plurality of blocking ribs, and the plurality of blocking ribs are distributed in parallel and at intervals.

[0019] In the above technical solution, intervals are provided between the multiple baffles, and the wind blown by the cooling fan can be blown out from the intervals, so that the multiple baffles will not affect the heat dissipation effect while blocking foreign objects; wherein, when the charging device is placed on the air outlet, the wireless charger starts working, and the foreign object exhaust port is in a closed state under the rotation of the baffle, but since it takes a certain amount of time for the baffle to rotate and the foreign objects to fall, or there is a possibility that the charging device does not completely block the air outlet, some foreign objects may still enter the heat dissipation duct at this time, and the set baffles can block the foreign objects, so that these foreign objects are accumulated on the side close to the foreign object exhaust port. After the charging device completes charging, the foreign object exhaust port is opened, and the foreign objects will automatically fall out of the foreign object exhaust port.

[0020] Optionally, in a possible implementation, a first air duct is provided on one side of the upper cover, and a second air duct is provided on one side of the heat sink, and the first air duct and the second air duct together constitute the heat dissipation air duct.

[0021] In the above technical solution, channels are provided on the same side of the upper cover and the heat sink, which are the first air duct and the second air duct respectively. After assembly, the first air duct and the second air duct are connected to form a heat dissipation air duct together.

[0022] Optionally, in a possible implementation manner, the upper cover is provided with a mounting groove for placing the filter board.

[0023] In the above technical solution, the mounting groove is arranged at the top of the upper cover for placing the filter board, and a hole is opened on the bottom of the mounting groove so that the upper cover and the cavity inside the base are connected. By avoiding air on the upper cover, the charging distance can be reduced and the charging speed can be accelerated.

[0024] This application has the following beneficial effects:

[0025] The present application is provided with a foreign object discharge port, and a rotatable baffle is provided in the foreign object discharge port, wherein the baffle is unevenly weighted. When the wireless charger is not working, the baffle can be rotated to a vertical state and maintained under the action of gravity due to the different weights on both sides, so that the foreign object discharge port is in an open state. At this time, if a foreign object falls into the air outlet, the foreign object will pass through the heat dissipation duct and fall out of the foreign object discharge port; when the charging device is placed on the top surface of the shell, the wireless charger is in a working state, and the heat dissipation fan is started at this time. The wind blown by the heat dissipation fan enters the heat dissipation duct. At this time, due to the placement of the charging device, the foreign object will fall into the heat dissipation duct. It is placed on the air outlet to block the air outlet, so that foreign matter cannot enter the wireless charger through the air outlet. At the same time, the baffle rotates under the action of wind pressure and abuts against both sides of the foreign matter exhaust port, thereby blocking the foreign matter exhaust port and closing the foreign matter exhaust port. The wind blown by the cooling fan will not leak out from the foreign matter exhaust port, but will be blown out from the air outlet to dissipate heat for the charging device placed on the air outlet. The wireless charger structure of the present application can realize the discharge function of foreign matter without affecting the heat dissipation effect, thereby effectively ensuring the normal operation of the wireless charger.
