A special heat dissipation wireless charger for a game mobile phone

Abstract

This utility model relates to the field of wireless charger technology, and more particularly to a heat-dissipating wireless charger specifically for gaming phones. It includes a housing, a wireless charging module, a cooling fan, and a heat sink. The wireless charging module, employing a magnetic charging structure, is mounted on the front side wall of the housing. A cooling fan is installed inside the rear side of the housing, which has a hollow structure. The cooling fan is electrically connected to the wireless charging module. A heat sink is installed inside the front side of the housing, fitting snugly against the rear side wall of the wireless charging module. The cooling fan and heat sink work together to create an effective active cooling airflow. The heat sink directly absorbs the high heat generated by the wireless charging module during operation, while the cooling fan draws in cool external air, which flows over the heat sink and quickly dissipates its heat through the surrounding ventilation holes. This effectively controls the temperature of the area where the charger contacts the phone, ensuring stable and safe high-power charging over extended periods.

Description

Technical Field

[0001] This utility model relates to the field of wireless charger technology, and in particular to a heat dissipation wireless charger specifically for gaming mobile phones. Background Technology

[0002] With the rapid development of smartphones, especially high-performance gaming phones, their power consumption and heat generation have also increased significantly. Wireless charging technology is becoming increasingly popular due to its convenience, but during high-power charging, the charging module itself and the back of the phone generate a lot of heat. If the heat cannot be dissipated in time, it will not only cause the charging efficiency to decrease due to the high-temperature protection mechanism, but also aggravate the heat accumulation in the phone itself, causing problems such as processor throttling and unstable game frame rates, seriously affecting the user experience and even accelerating the aging of the device's battery.

[0003] Currently, some wireless chargers on the market attempt to integrate heat dissipation functions, with a common solution being the addition of a fan inside the charger. However, many designs suffer from unreasonable airflow layouts. For example, the airflow path fails to directly and efficiently flow through the core heat-generating area (i.e., the wireless charging coil), resulting in limited heat dissipation; or the heat dissipation airflow is independent of the device's mounting structure, failing to form a synergistic effect. Furthermore, simple forced air cooling may lead to dust accumulation or a decrease in heat dissipation efficiency over time due to poorly designed air inlets and outlets.

[0004] Therefore, there is an urgent need for a wireless charger that can achieve efficient and directional heat dissipation, and whose heat dissipation structure is organically combined with the device fixing mechanism, so as to provide stable charging and environmental protection for high-performance mobile phones under long-term high-load scenarios. Utility Model Content

[0005] In order to overcome the shortcomings of existing wireless chargers, such as insufficient heat dissipation efficiency, unreasonable airflow design, and independent device fixing and heat dissipation structures when targeting high-performance devices such as gaming phones, this utility model provides a dedicated heat dissipation wireless charger for gaming phones.

[0006] The technical solution is as follows: A dedicated wireless charger for gaming phones, comprising a shell, a wireless charging module, a cooling fan, a heat sink, and a reinforcement component. The wireless charging module is installed on the front side wall of the shell and adopts a magnetic charging structure. A cooling fan is installed on the rear side inside the shell, and the rear side wall of the shell has a hollow structure. The cooling fan is electrically connected to the wireless charging module. A heat sink is installed on the front side inside the shell and is attached to the rear side wall of the wireless charging module. Several ventilation holes are spaced circumferentially on the outer peripheral wall of the shell corresponding to the position of the heat sink. The wireless charging module is provided with a reinforcement component.

[0007] Furthermore, the heat sink is made of copper.

[0008] Furthermore, the reinforcement components include a round tube, a connecting tube, a suction cup, a reset spring, and a venting component. The wireless charging module has multiple through holes spaced apart along its circumference. Each through hole is sealed and slidably connected to a connecting tube. A suction cup is fixedly installed at the front end of each connecting tube, and the inner cavity of the suction cup communicates with the inner cavity of the connecting tube. The rear end of each connecting tube extends into the inner cavity of the outer shell and is slidably connected to a round tube. A vent is opened on the outer wall of the rear end of each connecting tube. One end of the vent connects to the inner cavity of the round tube, and the other end connects to the inner cavity of the connecting tube. A reset spring is sleeved on the outside of each connecting tube. The front end of the reset spring is fixedly connected to the connecting tube, and the rear end of the reset spring is fixedly connected to the front side wall of the round tube. A venting component is provided on the outer shell.

[0009] Furthermore, the suction cup is made of soft and highly resilient silicone material.

[0010] Furthermore, the venting assembly includes a venting pipe, a pressure button, a clamping spring, and a sealing plate. The venting pipe is embedded in the middle of the top of the outer shell, and its bottom end extends into the inner cavity of the outer shell and is sealed and fixedly connected to the round tube. The inner cavity of the venting pipe is interconnected with the inner cavity of the round tube. A pressure button is slidably connected to the top of the venting pipe, and a sealing plate is fixedly connected to the bottom end of the pressure button. An annular boss is provided inside the venting pipe, which divides the inner cavity of the venting pipe into an upper chamber and a lower chamber. Multiple through holes are spaced apart on the annular boss inside the venting pipe, and each through hole connects to the upper chamber and the lower chamber of the venting pipe. Multiple adapter holes are spaced apart on the sealing plate, and the upper surface of the sealing plate fits against the lower surface of the annular boss and seals the lower port of the through hole. Multiple vent holes are provided on the outer side of the upper end of the venting pipe. One end of the vent hole connects to the upper chamber of the venting pipe, and the other end connects to the inner cavity of the outer shell. A clamping spring is provided in the upper chamber of the venting pipe. The upper end of the clamping spring is fixedly connected to the lower surface of the pressure button, and the lower end of the clamping spring is fixedly connected to the upper surface of the annular boss of the venting pipe.

[0011] Furthermore, an O-ring is fitted around the outer periphery of the sealing plate.

[0012] The beneficial effects are as follows: 1. The cooling fan and heat sink work together to create an effective active heat dissipation channel. The heat sink directly absorbs the high heat generated when the wireless charging module is working, while the cooling fan draws in external cold air, which flows through the heat sink and quickly removes its heat through the surrounding ventilation holes. This effectively controls the temperature of the area where the charger and the phone are in contact, ensuring the stability and safety of long-term high-power charging.

[0013] 2. Through the dual fixing mechanism of magnetic attraction and negative pressure adsorption, the stability of the mobile phone during the charging process is significantly improved. The magnetic structure is responsible for quick alignment and initial fixation, while the negative pressure formed by the suction cup after the air is expelled can generate a strong adsorption force, effectively preventing the mobile phone from coming off the charger when vibrating during games or being accidentally touched, ensuring a continuous and reliable charging connection.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0020] Example: A wireless charger for gaming phones with heat dissipation function, such as... Figures 1-4 As shown, the device includes a housing 1, a wireless charging module 101, a cooling fan 2, a heat sink 3, and reinforcing components. The wireless charging module 101 is mounted on the front side wall of the housing 1. The wireless charging module 101 adopts a magnetic charging structure (built-in magnet array) for quick alignment with the magnet on the gaming phone. The cooling fan 2 is bolted to the rear side of the inside of the housing 1. The rear side wall of the housing 1 has a hollow structure to allow air circulation between the inner cavity of the housing 1 and the outside. The cooling fan 2 is electrically connected to the wireless charging module 101. The heat sink 3 is mounted on the front side of the inside of the housing 1. The heat sink 3 is attached to the rear side wall of the wireless charging module 101 to absorb the heat generated by the wireless charging module 101. The heat sink 3 is made of copper, which has excellent thermal conductivity and can quickly absorb and conduct the heat generated by the wireless charging module 101. Several ventilation holes 31 are spaced circumferentially on the outer peripheral wall of the housing 1 corresponding to the position of the heat sink 3 to allow the heat dissipation airflow to be discharged. The wireless charging module 101 is equipped with reinforcing components.

[0021] like Figures 2-4As shown, the reinforcement assembly includes a round tube 4, a connecting tube 5, a suction cup 6, a return spring 7, and a venting assembly. Multiple through holes are spaced apart along the circumference of the wireless charging module 101. A connecting tube 5 is slidably connected through each through hole, and the front end of the connecting tube 5 protrudes from the front side of the wireless charging module 101. A suction cup 6 is fixedly mounted on the front end of each connecting tube 5. The inner cavity of the suction cup 6 communicates with the inner cavity of the connecting tube 5. The suction cup 6 is made of soft and highly resilient silicone material. The soft texture of the silicone material allows it to better conform to the curved surfaces of different phone back covers, ensuring the suction cup 6... It forms a good seal with the surface of the mobile phone, thereby generating a stronger and more stable adsorption force. The rear end of the connecting tube 5 extends into the inner cavity of the outer shell 1 and is slidably connected to a round tube 4. The outer wall of the rear end of the connecting tube 5 is provided with a vent hole 8. One end of the vent hole 8 is connected to the inner cavity of the round tube 4, and the other end is connected to the inner cavity of the connecting tube 5. A return spring 7 is sleeved on the outside of each connecting tube 5. The front end of the return spring 7 is fixedly connected to the connecting tube 5, and the rear end of the return spring 7 is fixedly connected to the front side wall of the round tube 4. The outer shell 1 is provided with a venting component to control the air circulation between the inner cavity of the round tube 4 and the outside.

[0022] like Figures 2-4 As shown, the venting assembly includes a vent pipe 9, a pressure button 11, a compression spring 12, and a sealing plate 13. The vent pipe 9 is embedded in the middle of the top of the outer casing 1. The bottom end of the vent pipe 9 extends into the inner cavity of the outer casing 1 and is sealed and fixedly connected to the circular tube 4. The inner cavity of the vent pipe 9 communicates with the inner cavity of the circular tube 4. The pressure button 11 is vertically slidably connected to the top of the vent pipe 9, with its upper end exposed on the top of the outer casing 1 (for easy operation). The sealing plate 13 is fixedly connected to the bottom end of the pressure button 11. An annular boss is provided inside the vent pipe 9, dividing the inner cavity of the vent pipe 9 into an upper chamber and a lower chamber. The outer peripheral wall of the sealing plate 13 is sealed and slidably fitted with the inner wall of the lower chamber of the vent pipe 9. Four through holes 10 are spaced circumferentially along the annular boss inside the vent pipe 9, each through hole 10 connecting the upper and lower chambers of the vent pipe 9. The sealing plate... Four adapter holes 15 are spaced apart circumferentially on the upper part of the sealing plate 13. In the initial state, the adapter holes 15 are offset from the through holes 10, so that the upper surface of the sealing plate 13 fits against the lower surface of the annular boss, sealing the lower port of the through hole 10. Multiple air outlet holes 14 are spaced apart circumferentially on the outer side of the upper end of the vent pipe 9. One end of the air outlet hole 14 is connected to the upper chamber of the vent pipe 9, and the other end is connected to the inner cavity of the outer shell 1 (indirectly connected to the outside). The upper chamber of the vent pipe 9 is equipped with a compression spring 12. The upper end of the compression spring 12 is fixedly connected to the lower surface of the button 11, and the lower end of the compression spring 12 is fixedly connected to the upper surface of the annular boss of the vent pipe 9, which is used to drive the button 11 to return to its axial position. An O-ring is fitted on the outer periphery of the sealing plate 13 to enhance the sealing between it and the inner wall of the vent pipe 9 and prevent air from leaking from there in the adsorption state.

[0023] When charging a gaming phone, the user holds the charger and places the charging end of the wireless charging module 101 against the back of the phone, applying axial pressure towards the phone. This pressure drives the connecting tube 5 to move axially relative to the circular tube 4, simultaneously compressing the return spring 7. As the suction cup 6 is compressed, air between it and the back of the phone is expelled through its edge, significantly reducing the air content inside the suction cup 6 and creating a negative pressure state. The suction cup 6 then adheres to the back of the phone under atmospheric pressure, securing the phone and charger firmly. Simultaneously, the built-in magnet array of the wireless charging module 101 quickly magnetically attracts the magnet on the phone, precisely guiding the transmitting coil of the wireless charging module 101 to the receiving coil of the phone. To ensure accurate alignment during wireless charging, the wireless charging module 101 is powered on. Its transmitting coil generates an alternating magnetic field, and the receiving coil of the mobile phone induces an alternating current. After rectification and voltage stabilization inside the mobile phone, a safe voltage and current are output to charge the battery. During the charging process, the cooling fan 2 is powered on and started simultaneously. Under the negative pressure of the cooling fan 2, outside air enters the inner cavity of the outer shell 1 through the hollow structure on the rear side wall of the outer shell 1 and flows through the heat sink 3 (which absorbs the heat generated by the wireless charging module 101). The air that has absorbed heat is discharged to the outside through the ventilation holes 31 on the outer peripheral wall of the outer shell 1 under the air guiding action of the cooling fan 2, forming an active cooling airflow to ensure the stability and safety of the operation of the wireless charging module 101.

[0024] When the phone is fully charged and needs to be removed, press the button 11 downwards along the axis. The button 11 compresses the clamping spring 12 and causes the sealing plate 13 to slide downwards along the lower chamber of the vent pipe 9 until the upper surface of the sealing plate 13 separates from the lower surface of the annular boss. The lower port of the through hole 10 is then released from its closure, and the lower chamber communicates with the through hole 10 through the adapter hole 15. Outside air enters the upper chamber of the vent pipe 9 through the vent hole 14, flows sequentially through the through hole 10, the adapter hole 15, and the lower chamber of the vent pipe 9 into the inner cavity of the circular tube 4, and then through the connecting pipe 5. The air flows into the inner cavity of the suction cup 6 through the vent 8, balancing the air pressure inside the suction cup 6 with the external atmospheric pressure. The negative pressure is released, and the suction cup 6 releases its grip on the mobile phone. At this time, the mobile phone can be easily separated from the wireless charging module 101. After releasing the button 11, the compression spring 12 releases its elastic potential energy, driving the button 11 to return to its axial position and simultaneously moving the sealing plate 13 upward until the sealing plate 13 re-attaches to the annular boss and seals the lower port of the through hole 10, blocking the airflow between the vent pipe 9 and the outside. The device returns to its initial state, ready for the next use.
