Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted electronic devices, and in particular to a vehicle-mounted magnetic wireless charger. Background Technology

[0002] Currently, most cars are equipped with wireless chargers for charging wirelessly-enabled electronic devices such as mobile phones, smartwatches, and fitness trackers. Some wireless chargers contain a TEC cooler, which consists of a cold side and a hot side. When current passes through, the cold side absorbs heat, and the hot side releases heat. The cold side is used to cool the coils and electronic devices inside the charger, while the hot side is usually connected to a heat sink to dissipate the heat emitted by the hot side.

[0003] Wireless chargers with TEC cooling typically have a fan. The fan draws air in through the top vent, flowing through the charger's interior and over the heatsink. This air cooling helps dissipate heat from the heatsink, preventing heat buildup inside the charger. Existing wireless chargers usually have their vents on the charging panel, which is aesthetically unappealing and prone to dust accumulation. Foreign objects can also easily enter the charger through the vents, affecting its normal operation. Furthermore, while current wireless chargers often use finned heatsinks to improve heat dissipation, this method offers very limited cooling capacity and is no longer sufficient to meet increasingly demanding cooling requirements. Utility Model Content

[0004] In view of this, the present invention provides a car-mounted magnetic wireless charger with a hidden air vent design and excellent heat dissipation.

[0005] A vehicle-mounted magnetic wireless charger includes a panel, a housing, and a fan arranged sequentially from top to bottom. The top of the housing has a raised boss, and the panel has a hole for the boss to pass through. The sides of the boss have multiple air inlets. Inside the housing, from top to bottom, a charging component, a TEC cooler, and a heat sink are arranged sequentially. The charging component is installed inside the boss and includes a coil and a magnetic ring. The top and bottom surfaces of the TEC cooler are in contact with the charging component and the heat sink, respectively. The heat sink includes multiple ventilation openings and heat dissipation ribs arranged at intervals. Each ventilation opening is provided with a heat dissipation rib below it. The bottom of the housing has an air outlet located below the heat dissipation ribs, and the fan is mounted on the air outlet.

[0006] In the above technical solution, the panel can serve as the interior trim of the vehicle. The protrusion passes through the hole on the panel. During charging, the device is placed on the protrusion, and the magnetic ring inside the protrusion attracts and fixes the device. The coil charges the device. The TEC cooler is located below the charging component. Its cold side contacts the bottom of the charging component to cool it down, and its hot side contacts the heat sink to transfer the generated heat to the heat sink. During the charging process, under the suction of the fan at the bottom of the housing, the airflow enters the housing from the air inlet on the side of the protrusion, then passes through the heat sink to cool it down, and finally exits the housing through the air outlet at the bottom and the fan.

[0007] It should be noted that the heatsink has multiple ventilation openings spaced apart, and each ventilation opening is positioned directly below a heat dissipation rib. The gaps between the ventilation openings can be considered as a type of rib, which, together with the heat dissipation rib below, forms a staggered structure. When airflow reaches the heatsink, guided by the ventilation openings and heat dissipation ribs, the airflow can pass vertically through the heatsink. The staggered rib structure effectively increases the contact area between the airflow and the heatsink, ensuring full contact between the airflow and the heatsink and improving heat dissipation efficiency. At the same time, allowing the airflow to flow vertically through the heatsink is more conducive to carrying away heat. Compared with the traditional heatsink fin design, the heat dissipation effect is better.

[0008] In one embodiment, the heat sink includes a partition that is perpendicularly disposed through the heat sink, and the interior of the housing is divided into two cavities by the partition, with the heat dissipation ribs located in one of the cavities.

[0009] In the above technical solution, the interior of the housing is divided into two cavities by a partition on the heat sink. The air inlet is connected to the cavity containing heat dissipation ribs, so that the airflow entering the housing passes through the ventilation opening and heat dissipation ribs, thereby guiding the airflow, improving airflow utilization efficiency, and enhancing heat dissipation. At the same time, the other cavity can be used to place the circuit board, thereby separating the charger's air duct system from the internal circuit board, preventing liquids that accidentally enter from the air inlet from affecting the circuit board, and meeting waterproof requirements.

[0010] In one embodiment, the housing includes a top cover and a base. Mounting blocks are provided on both sides inside the top cover. Each mounting block has a first slot and a second slot. The first slot cooperates with the partition. Inserts that cooperate with the second slot are provided on both sides inside the base.

[0011] In the above technical solution, two mounting blocks are located on both sides of the bottom of the boss, the first slot and the second slot are located on both sides of the mounting blocks respectively, the top sides of the partition are inserted into the first slot, and the insert on the base is inserted into the second slot of the mounting block. The mounting blocks are used to limit the partition and the base, ensuring that the top cover and the base are installed stably.

[0012] In one embodiment, the inserts are provided with slots that cooperate with the partition.

[0013] In the above technical solution, the bottom of the partition is inserted into the slot to fix and limit the heat sink. The insert and the partition together divide the inside of the housing into two parts.

[0014] In one embodiment, a PCBA board is further provided inside the housing, the PCBA board is located below the heat sink, and the PCBA board and the heat dissipation ribs are located on both sides of the partition.

[0015] In the above technical solution, the partition divides the internal space of the shell into two parts. The PCBA board and the heat dissipation fins are located on both sides of the partition, which separates the PCBA board from the air duct system and improves the waterproof and moisture-proof capabilities of the PCBA board.

[0016] In one embodiment, the bottom of the housing is further provided with an auxiliary heat dissipation port, which is located below the PCBA board, and an auxiliary heat dissipation fin is installed inside the auxiliary heat dissipation port.

[0017] In the above technical solution, an auxiliary heat sink is installed inside the auxiliary heat dissipation port to dissipate heat from the cavity on the side where the PCBA board is installed, thereby preventing heat from accumulating in the cavity where the PCBA board is installed and ensuring the overall heat dissipation capacity of the charger.

[0018] In one embodiment, the heat sink includes a mounting platform, the top of which has a mounting groove, and the TEC cooler is mounted in the mounting groove.

[0019] In the above technical solution, the dimensions of the mounting platform and the boss are matched to seal the bottom of the boss, and the mounting groove protrudes from the top of the mounting platform for installing the TEC cooler.

[0020] In one embodiment, the mounting platform is provided with a wiring hole, which is located on one side of the mounting groove.

[0021] In the above technical solution, the connection wires of the charging component and the TEC cooler can be connected to the PCBA board below through the wiring holes.

[0022] In one embodiment, the housing is further provided with a first antenna and a second antenna, the first antenna being mounted on top of the charging assembly and the second antenna being mounted on the top of the inner side of the housing.

[0023] In the above technical solution, the first antenna and the second antenna are used to identify the charging device. The second antenna is installed on the top of the inner side of the housing. The second antenna has a hole to make way for the mounting platform on the heat sink. The first antenna is installed on the charging assembly, which fills the gap in the second antenna, thereby ensuring that the charger can identify the device at all locations and improving the reliability of use.

[0024] In one embodiment, the top of the boss is provided with a decorative piece for closing the boss.

[0025] In the above technical solution, the top of the boss is sealed with a decorative piece to prevent foreign objects from falling into the housing.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] The top of the housing of this utility model is provided with a protrusion protruding from the panel, and the air inlet is located on the side of the protrusion, which is not easy to find, realizing a hidden air inlet design. The appearance is more beautiful and can effectively prevent foreign objects from falling in. In addition, when the device is charging, it can be placed on the protrusion to avoid direct contact between the back of the device and the panel. When the airflow passes through, it can also dissipate heat from the device and effectively reduce the temperature of the device. The heat sink of this utility model adopts a staggered rib structure, which can effectively increase the contact area between the airflow and the heat sink, and can make the airflow pass through the heat sink perpendicularly, which is more conducive to carrying away heat. Compared with the traditional heat sink fin design, the heat dissipation effect is better. Attached Figure Description

[0043] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Example

[0046] Please refer to Figures 1 to 11 This embodiment provides a vehicle-mounted magnetic wireless charger, which includes a panel 1, a housing 2, and a fan 9 arranged and connected sequentially from top to bottom. The top of the housing 2 is provided with a raised circular boss 211. The panel 1 is provided with a hole for the boss 211 to pass through. The side of the boss 211 is provided with multiple air inlets 212. Inside the housing 2, from top to bottom, a charging component 3, a TEC cooler 5, and a heat sink 4 are arranged sequentially. The charging component 3 is installed inside the boss 211. The charging component 3 includes a coil 31 and a magnetic ring 32. The upper and lower sides of the TEC cooler 5 are in contact with the charging component 3 and the heat sink 4, respectively. The heat sink 4 includes multiple ventilation openings 41 and heat dissipation ribs 42 arranged at intervals. A heat dissipation rib 42 is provided below each ventilation opening 41. The bottom of the housing 2 is provided with an air outlet 221, which is located below the heat dissipation ribs 42. The fan 9 is installed on the air outlet 221.

[0047] In this embodiment, panel 1 can be directly used as interior trim in the vehicle or installed on interior trim. Boss 211 passes through the hole on panel 1. During charging, the device is placed on boss 211, and the magnetic ring 32 inside boss 211 attracts and fixes the device. The device is charged through coil 31. TEC cooler 5 is located below charging component 3. Its cold side contacts the bottom of charging component 3 to cool and lower the charging component 3, and its hot side contacts heat sink 4 to transfer the generated heat to heat sink 4, which then dissipates the heat. During charging, under the suction of fan 9 at the bottom of housing 2, airflow enters housing 2 from air inlet 212 on the side of boss 211, then passes through heat sink 4 for air cooling, and finally exits housing 2 through air outlet 221 at the bottom and fan 9.

[0048] Preferably, both the cold and hot surfaces of the TEC cooler 5 are coated with thermally conductive gel, which contacts the charging component 3 and the heat sink 4 to improve the temperature conduction effect.

[0049] The heat sink 4 has multiple ventilation openings 41 spaced apart, and each ventilation opening 41 has a heat dissipation rib 42 directly below it. The gaps between the multiple ventilation openings 41 can be regarded as a kind of rib, which forms a staggered structure with the heat dissipation rib 42 below. When the airflow reaches the heat sink 4, under the guidance of the ventilation openings 41 and the heat dissipation ribs 42, the airflow can pass vertically through the heat sink 4. The staggered rib structure design can effectively increase the contact area between the airflow and the heat sink 4, so that the airflow can fully contact the heat sink 4 and improve the heat dissipation efficiency. At the same time, the vertical flow of the airflow through the heat sink 4 is more conducive to carrying away heat. Compared with the traditional heat dissipation fin design, the heat dissipation effect is better.

[0050] It should be noted that when viewed from a top-down angle (such as...) Figure 5 As shown), the width of the heat dissipation ribs 42 is smaller than the width of the ventilation opening 41, allowing airflow to smoothly enter the gaps between the heat dissipation ribs 42 from the ventilation opening 41. (See side view). Figure 6 As shown), the two ends of the heat dissipation rib 42 are connected to the bottom surface of the heat sink 4. The heat dissipation rib 42 and the bottom of the ventilation opening 41 are kept at a certain distance to avoid blocking the airflow and to allow the airflow to pass through more smoothly. In addition, in order to make way for the related structures on the heat sink 4, the length of the ventilation opening 41 in this embodiment is not exactly the same. In specific implementation, the length of the ventilation opening 41 can be flexibly adjusted as needed.

[0051] Please refer to Figures 2 to 11 The housing 2 includes a snap-fit ​​upper cover 21 and a base 22, which are detachably connected by screws (screws omitted in the figure). The upper cover 21 contains two mounting blocks 213 located on either side of the bottom opening of the boss 211. Each mounting block 213 includes a first slot 2131 and a second slot 2132 located on either side. The base 22 contains two inserts 222, with a slot 223 between them. A partition 43 is provided on the heat sink 4, perpendicularly passing through it. All the heat-generating ribs 42 are located on the same side of the partition 43. The upper and lower ends of the partition 43 protrude from the upper and lower sides of the heat sink 4, respectively. The top of the partition 43 is inserted into the first slot 2131, the insert 222 on the base 22 is inserted into the second slot 2132 of the mounting block 213, and the bottom of the partition 43 is inserted into the slot 223. Through the combined design of the mounting block 213, the insert 222, the slot 223 and the partition 43, the interior of the housing 2 is divided into two cavities. At the same time, the top cover 21, the base 22 and the heat sink 4 can be limited to ensure stable installation.

[0052] Furthermore, referring to Figure 11As shown in the diagram, the arrows indicate the airflow direction. The interior of the housing 2 is divided into two cavities, left and right, by a partition 43. The heat dissipation ribs 42 are located in the left cavity, and the air outlet 221 is located at the bottom of the left cavity. The air inlet 212 is only provided on the left side of the boss 211, so that the air inlet 212 is connected to the left cavity, thereby guiding the airflow to the ventilation opening 41 of the heat sink 4, improving the utilization efficiency of the airflow. The right cavity is provided with a PCBA board 6 for controlling the operation of the entire charger. The PCBA board 6 is installed below the heat sink 4. The partition 43 is used to separate the PCBA board 6 from the air duct system, preventing liquids that accidentally enter from the air inlet 212 from affecting the PCBA board 6, improving the waterproof and moisture-proof capabilities of the PCBA board 6, and meeting the waterproof requirements of the charger.

[0053] Preferably, the bottom of the housing 2 is also provided with an auxiliary heat dissipation port 224. The auxiliary heat dissipation port 224 is located below the PCBA board 6, that is, at the bottom of the right cavity. An auxiliary heat dissipation fin 2241 is installed in the auxiliary heat dissipation port 224 to dissipate heat on the side cavity where the PCBA board 6 is installed, so as to avoid heat accumulation in the right cavity, so that the PCBA board 6 can work normally and improve the overall heat dissipation capacity of the charger.

[0054] In addition, a plug-in interface 226 is provided on one side of the auxiliary heat dissipation port 224, and the interface of the PCBA board 6 is located at the plug-in interface 226, so that it can be electrically connected to the outside.

[0055] Please refer to Figures 4 to 7 The heat sink 4 includes a mounting platform 44, and the top of the mounting platform 44 is provided with a mounting groove 441, in which the TEC cooler 5 is installed.

[0056] Preferably, the mounting platform 44 is circular and matches the size of the boss 211. After installation, the mounting platform 44 can close the bottom of the boss 211, making the overall structure more compact. The mounting groove 441 protrudes from the top of the mounting platform 44 and is used to install the TEC cooler 5.

[0057] Preferably, the mounting platform 44 is provided with a wiring hole 442 that extends along the thickness direction. The wiring hole 442 is located on one side of the slot 223. The connection wires of the charging component 3 and the TEC cooler 5 can be connected to the PCBA board 6 through the wiring hole 442.

[0058] Please refer to Figure 2 The top of the charging component 3 is provided with a first antenna 7, and the top of the inner side of the housing 2 is provided with a second antenna 8. Both the first antenna 7 and the second antenna 8 are NFC antennas with NFC identification function for identifying charging devices. The second antenna 8 has a hole to make way for the mounting platform 44. The first antenna 7 is installed on the charging component 3, which fills the empty part of the second antenna 8, thereby ensuring that the charger can identify the device at all positions and improving the reliability of use.

[0059] Preferably, the first antenna 7 is an FPC antenna, which is a flexible structure that is easy to manufacture into various shapes. The first antenna 7 is provided with a connection end 71, which is connected to the PCBA board 6 through the wiring hole 442 on the mounting platform 44.

[0060] Specifically, the second antenna 8 has a slot 223 on its side and a limiting post 225 at the corner of the base 22. The slot 223 and the limiting post 225 limit the second antenna 8.

[0061] Please refer to Figure 1 and Figure 2 The top of the protrusion 211 is provided with a decorative piece 2111. The bottom surface of the decorative piece 2111 contacts the charging component 3 through thermally conductive gel, sealing the protrusion 211 to prevent foreign objects from falling into the interior.

[0062] Preferably, the decorative piece 2111 is made of ceramic, which has good temperature conductivity. The bottom surface of the decorative piece 2111 is in contact with the charging component 3 through thermally conductive gel. When the device is placed on the boss 211 for charging, the back of the device is in contact with the decorative piece 2111. The cooling energy of the TEC cooler 5 on the charging component 3 can be conducted to the back of the device through the decorative piece 2111, thereby cooling the charging device and preventing overcharge protection.

[0063] It should be noted that the magnetic ring 32 has a certain temperature conduction capability, and the cold energy generated by the TEC cooling surface can be transferred to the decorative piece 2111 through the magnetic ring 32.

[0064] Please refer to Figures 1 to 3 In this embodiment, the bottom of the housing 2 is also provided with a housing 91 for mounting the fan 9. The housing 91 is detachably mounted on the air outlet 221 at the bottom of the base 22 by screws.

[0065] Taking mobile phone charging as an example, the working principle of this utility model is as follows:

[0066] When the phone needs charging, it is placed on the protrusion 211 and positioned and fixed by the magnetic ring 32. After the phone is detected, the PCBA board 6 controls the change in magnetic flux of the coil 31 to start charging the phone. At the same time, under the control of the PCBA board 6, the fan 9 and the TEC cooler 5 are activated. Under the suction of the fan 9, the airflow enters from the air inlet 212 and passes through the heat sink 4 to dissipate heat. Finally, the airflow is discharged from the air outlet 221. Meanwhile, the cold side of the TEC cooler 5 cools the charging component 3, and the hot side conducts heat to the heat sink 4. The cooling energy of the cold side of the TEC cooler 5 can be transferred to the bottom of the phone through the charging component 3 and the decorative piece 2111 to achieve the purpose of heat dissipation, avoid overcharge protection, and improve the user's charging experience.
