Description

Technical Field

[0001] This application relates to the field of charging technology, specifically to a multi-channel heat dissipation charging device. Background Technology

[0002] Charging devices can charge devices with low battery levels. During charging, the charging device itself generates heat, affecting charging efficiency, the device's lifespan, and user experience. Under current technology, some charging devices rely on natural heat dissipation. This results in high internal temperatures during use, making it difficult to dissipate heat quickly. Some charging devices have built-in cooling systems, such as fans, which use airflow to dissipate heat. However, this leads to turbulent airflow inside the device, resulting in low heat dissipation efficiency. Utility Model Content

[0003] The main technical problem this invention addresses is the low cooling efficiency of the fan in existing charging devices.

[0004] One embodiment provides a multi-channel heat dissipation charging device, comprising:

[0005] The housing assembly includes a front shell and a base arranged opposite to and connected to each other, with an accommodating space formed between the front shell and the base. The front shell is provided with a first ventilation opening, and the base is provided with a third ventilation opening. The accommodating space is provided with a first ventilation channel and a second ventilation channel.

[0006] An airflow actuator, disposed in the accommodating space, has a fourth vent and a sixth vent. One end of the first ventilation channel is connected to the first vent and the other end is connected to the fourth vent. One end of the second ventilation channel is connected to the third vent and the other end is connected to the sixth vent. The airflow actuator drives air to flow from the first ventilation channel to the second ventilation channel.

[0007] And a charging component, disposed in the accommodating space, for electrically connecting an externally mounted device to be charged in the multi-channel heat dissipation charging device to charge the device to be charged.

[0008] In some embodiments, the base is further provided with a second vent, the airflow actuator is further provided with a fifth vent, and the accommodating space is further provided with a third ventilation channel. One end of the third ventilation channel is connected to the second vent, and the other end is connected to the fifth vent. The airflow actuator drives air to flow from the first ventilation channel and the third ventilation channel to the second ventilation channel.

[0009] In some embodiments, the extending directions of the first ventilation channel and the third ventilation channel are different from the extending direction of the second ventilation channel.

[0010] In some embodiments, the fourth vent and the fifth vent are located on opposite sides of the airflow driver, and the sixth vent is located on the side between the fourth vent and the fifth vent.

[0011] In some embodiments, the multi-channel heat dissipation charging device includes a charging component comprising a circuit board and a charging coil, wherein the charging coil is disposed within a first ventilation channel formed by the first vent and the fourth vent, and the circuit board is disposed within a second ventilation channel formed by the second vent and the fifth vent.

[0012] In some embodiments, some components on the circuit board extend into the second ventilation channel.

[0013] In some embodiments, the base has a bottom wall and a plurality of first side walls connected end to end, the bottom wall being spaced apart from the face shell, one of the plurality of first side walls being provided with the third vent, and the second vent being provided on the bottom wall and / or the remaining first side walls.

[0014] In some embodiments, the charging assembly further includes a temperature sensor electrically connected to the circuit board and used to detect the temperature of the charging coil and / or the device to be charged; the circuit board is configured to control the airflow driver based on the temperature information obtained by the temperature sensor.

[0015] In some embodiments, the faceplate has a plurality of exposed support bosses, which are arranged at intervals around the first vent; the support bosses are used to support the device to be charged, so as to form a third air intake channel communicating with the first vent between the faceplate and the device to be charged.

[0016] In some embodiments, in the arrangement direction of the faceplate and the base, the geometric center line of the third vent is inclined toward the side away from the faceplate.

[0017] According to the multi-channel heat dissipation charging device of the above embodiment, the airflow driver drives air to flow from the first ventilation channel to the second ventilation channel. During the air flow, the heat on the charging component is carried away. Since the first ventilation channel and the second ventilation channel are set independently, the cold air entering the housing and the hot air flowing out of the housing flow along the first ventilation channel and the second ventilation channel respectively. The cold air and the hot air are less likely to collide and mix, resulting in smoother air flow and higher heat dissipation efficiency. Attached Figure Description

Detailed Implementation

[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0030] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0031] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] like Figure 1 , Figure 2 As shown, a multi-channel heat dissipation charging device includes a housing assembly, a drive assembly, and a charging assembly. The housing assembly forms an accommodating space to house the drive assembly and the charging assembly. The drive assembly drives air to circulate between the interior and exterior of the housing assembly to remove heat from the interior. The charging assembly is disposed in the accommodating space and electrically connects to an external device to be charged, thereby charging the device. Heat generated during charging can be dissipated by the drive assembly.

[0033] like Figure 3 , Figure 4As shown, the housing assembly includes a faceplate 300 and a base 100 arranged opposite to and connected to each other. An accommodating space is formed between the faceplate 300 and the base 100. The base 100 serves as a mounting base for mounting the faceplate 300. The faceplate 300 is provided with a first vent 310, and the base 100 is provided with a third vent 130. The first vent 310 and the third vent 130 can be used to guide airflow between the interior and exterior of the housing assembly for heat dissipation. Specifically, the first vent 310 allows air to flow into the housing assembly, and the third vent 130 allows air to flow out of the housing assembly.

[0034] The accommodating space is provided with a first ventilation channel and a second ventilation channel. An airflow actuator 400400 is disposed in the accommodating space and has a fourth ventilation opening 410 and a sixth ventilation opening 430. One end of the first ventilation channel is connected to the first ventilation opening 310, and the other end is connected to the fourth ventilation opening 410; one end of the second ventilation channel is connected to the third ventilation opening 130, and the other end is connected to the sixth ventilation opening 430. The airflow actuator 400 drives air to flow from the first ventilation channel to the second ventilation channel. That is, within the accommodating space, the space connecting the first ventilation opening 310 and the fourth ventilation opening 410 forms the first ventilation channel; the space connecting the third ventilation opening 130 and the sixth ventilation opening 430 forms the second ventilation channel.

[0035] Specifically, the first ventilation channel and the second ventilation channel can be set independently. The first ventilation channel can be an air inlet channel, and the second ventilation channel can be an air outlet channel. Since the first ventilation channel and the second ventilation channel are set independently, the cold air entering the shell and the hot air flowing out of the shell flow along the first ventilation channel and the second ventilation channel respectively. The cold air and the hot air are less likely to collide and mix, resulting in smoother airflow and higher heat dissipation efficiency.

[0036] It is important to understand that the independent setting of the first ventilation channel and the second ventilation channel does not mean that the two are not connected. Rather, it means that the airflow restriction effect of the ventilation channel makes the incoming airflow and the outgoing airflow independent of each other. That is, most of the incoming airflow is confined within the first channel, and most of the outgoing airflow is confined within the second ventilation channel.

[0037] According to the multi-channel heat dissipation charging device of the above embodiment, the airflow driver drives air to flow from the first ventilation channel to the second ventilation channel. During the air flow, the heat on the charging component is carried away. Since the first ventilation channel and the second ventilation channel are set independently, the cold air entering the housing and the hot air flowing out of the housing flow along the first ventilation channel and the second ventilation channel respectively. The cold air and the hot air are less likely to collide and mix, resulting in smoother air flow and higher heat dissipation efficiency.

[0038] In some embodiments, the base 100 and the housing 300 can be connected in a variety of ways, such as at least one of adhesive bonding, snap-fitting, threaded connection, etc. The housing assembly can be a thin-walled structure. In some embodiments, the housing assembly can be made of a variety of materials, such as at least one of metal, plastic, and rubber.

[0039] The side of the faceplate 300 along the circumferential direction can be sealed to the base 100 to avoid gaps between the faceplate 300 and the base 100, thereby better controlling the airflow and allowing the air to circulate smoothly.

[0040] In some embodiments, such as Figure 2 , Figure 4 As shown, the housing 300 is used to support the device 800 to be charged. A gap can be formed between the housing 300 and the device 800 to be charged, so that air can circulate between the housing 300 and the device 800 to be charged, and to dissipate heat from the internal structure of the device 800 and the housing 300.

[0041] The first vent 310 can be a through hole, the axis of which can be perpendicular to the outer surface of the faceplate 300. The first vent 310 can also be a tapered hole, and the diameter of the first vent 310 can gradually decrease along the direction from the outside to the inside.

[0042] In some embodiments, the base 100 may have a bottom wall 101 and a plurality of first side walls 102 connected end to end, the bottom wall 101 being spaced apart from the surface shell 300; one end of each first side wall 102 is connected to the bottom wall 101 and the other end is connected to the surface shell 300, thereby enclosing and forming an accommodating space. One of the plurality of first side walls 102 is provided with a third ventilation opening 130, and the remaining of the bottom wall 101 and the plurality of first side walls 102 are provided with second ventilation openings 120. The plurality of first side walls 102 connected end to end can be formed in various shapes, such as at least one of cylindrical, rounded prism, etc., and their specific shapes can be set according to actual needs.

[0043] By placing the second vent 120 on the bottom wall 101 and / or the first side wall 102, and placing the third vent 130 on the second side wall 103, the directions of air inlet and outlet can be staggered, thus preventing the hot air generated after heat exchange from being drawn back into the housing assembly and affecting the heat dissipation effect.

[0044] The second vent 120 connects the inner and outer sides of the housing assembly, facilitating airflow between them. The second vent 120 can include various shapes, such as a round hole, an elongated hole, or other shaped through-holes, and its specific shape can be customized according to actual needs. Multiple second vents 120 can be arranged in an array.

[0045] In some embodiments, the bottom surface of the base wall 101 is provided with a plurality of support legs 150. The support legs 150 are used to create a gap between the bottom surface of the base wall 101 and the bearing surface, so as to prevent the second ventilation opening 120 on the bottom surface of the base 100 from being blocked and affecting air circulation. The bearing surface refers to the surface used to place the multi-channel heat dissipation charging device, such as a desktop. In some embodiments, the support legs 150 can be connected to the bearing surface in a variety of ways, such as adhesive, snap-fit, magnetic connection, etc., thereby improving the connection strength between the base 100 and the bearing surface, thereby improving the stability of the base 100.

[0046] In some embodiments, the drive assembly includes an airflow actuator 400 and a support frame 200. The support frame 200 can serve as a mounting base for mounting the airflow actuator 400. The support frame 200 is connected to the faceplate 300 and / or the base 100. In some embodiments, the support frame 200 can be connected to the faceplate 300 and / or the base 100 in various ways, such as abutment, snap-fit, threaded connection, welding, etc., thereby improving the overall stability of the support frame 200.

[0047] In some embodiments, such as Figure 2 , Figure 8 As shown, a ventilation space 110 is formed between the support frame 200 and the base 100, which is connected to the second ventilation port 120.

[0048] Ventilation space 110 is used to guide airflow. In some embodiments, ventilation space 110 is in communication with a plurality of second vents 120, and air can flow between the second vents 120 and the airflow actuator 400.

[0049] In some embodiments, there may be a gap between the charging component and the bottom wall 101, which can serve as a ventilation space 110. The size of the gap can be set according to actual needs.

[0050] An airflow actuator 400 is mounted on a support frame 200. The airflow actuator 400 is configured to drive airflow.

[0051] In some embodiments, such as Figure 7 As shown, the airflow actuator 400 includes a fourth vent 410, a fifth vent 420, and a sixth vent 430. The airflow actuator 400 can drive air to enter the interior of the airflow actuator 400 through the fourth vent 410 and the fifth vent 420, and then exhaust it outward through the sixth vent 430. Alternatively, it can drive air to flow inward through the sixth vent 430 into the airflow actuator 400, and then exhaust it outward through the fourth vent 410 and the fifth vent 420, thereby allowing air circulation. During the air circulation process, heat exchange can occur with the heating structure, thus achieving a cooling effect.

[0052] It is important to understand that when cold air flows in from the first vent, it can simultaneously cool the device to be charged, preventing heat from accumulating between the device and the housing components, resulting in better heat dissipation. Therefore, it is a preferred method for the airflow driver 400 to drive air into the interior of the airflow driver 400 from the fourth vent 410 and the fifth vent 420, and to exhaust it outward through the sixth vent 430.

[0053] In some embodiments, the fourth vent 410 and the fifth vent 420 may be located on opposite sides of the airflow actuator 400, and the sixth vent 430 may be located on the side between the fourth vent 410 and the fifth vent 420. The direction of airflow between the fourth vent 410 and the airflow actuator 400 or between the fifth vent 420 and the airflow actuator 400 may be perpendicular to the direction of airflow between the sixth vent 430 and the airflow actuator 400.

[0054] For example only, such as Figure 5 As shown, the fourth vent 410 and the fifth vent 420 can be located at opposite ends along the first direction, and the sixth vent 430 can be oriented towards the second direction. That is, the extending directions of the first and third ventilation channels are different from the extending direction of the second ventilation channel. The first direction may include the direction in which the multi-channel heat dissipation charging device is perpendicular to the device to be charged (e.g., Figure 5 The Z direction), the second direction (e.g., Figure 5 The X direction in the equation can be perpendicular to the first direction.

[0055] In some embodiments, the airflow driver 400 may include a turbine cooling fan that can simultaneously guide air into the turbine cooling fan from two directions and exhaust it outward from one direction. Alternatively, it can guide air into the turbine cooling fan from one direction and exhaust it outward from two directions.

[0056] In some embodiments, the airflow actuator 400 may also include other structures. For example, the airflow actuator 400 may have two symmetrically distributed fans, one fan for driving air to flow from the fifth vent 420 into the airflow actuator 400, and the other fan for driving air to flow from the fourth vent 410 into the airflow actuator 400. Air entering from the fourth vent 410 and the fifth vent 420 can be exhausted outward from the sixth vent 430. Alternatively, both fans can drive air to flow from the sixth vent 430 into the airflow actuator 400, one fan for driving air to flow from the airflow actuator 400 to the fifth vent 420, and the other fan for driving air to flow from the airflow actuator 400 to the fourth vent 410. The two fans can be activated simultaneously, or one of them can be activated selectively.

[0057] In some embodiments, the fourth vent 410 communicates with the first vent 310 to form a first ventilation channel. The sixth vent 430 communicates with the third vent 130 to form a second ventilation channel. The fifth vent 420 communicates with the ventilation space 110 to form a third ventilation channel by communicating with the ventilation space 110 and the second vent.

[0058] In some embodiments, the airflow actuator can drive air from the first ventilation channel and the third ventilation channel to the second ventilation channel respectively; or the airflow actuator can drive air from the second ventilation channel to the first ventilation channel and the third ventilation channel respectively.

[0059] In some embodiments, when the airflow driver 400 is running, it can draw air from outside the base 100 into the ventilation space 110 through the second vent 120, and finally flow into the airflow driver 400 through the fifth vent 420, thereby allowing air to circulate inside the third ventilation channel to dissipate heat from the structure in contact with the air.

[0060] Simultaneously, air outside the faceplate 300 can be drawn in through the first vent 310 and circulate within the first ventilation channel to dissipate heat from the structure it contacts, before flowing into the airflow actuator 400 through the fourth vent 410. Air flowing into the airflow actuator 400 from the third and first ventilation channels merges within the airflow actuator 400, then circulates in the second ventilation channel and is discharged outward through the third vent 130.

[0061] In some embodiments, when the airflow actuator 400 is operating, it can draw in outside air through the third vent 130 and allow it to flow into the airflow actuator 400 through the second ventilation channel. Under the action of the airflow actuator 400, the air entering the airflow actuator 400 can flow into the third ventilation channel and the first ventilation channel respectively. During this flow, the air exchanges heat with the structures it contacts, thus achieving heat dissipation. The air flowing in the third ventilation channel can be discharged through the second vent 120, and the air flowing in the first ventilation channel can be discharged through the first vent 310.

[0062] The charging component is used to electrically connect to the device 800 externally mounted on a multi-channel heat dissipation charging device for charging the device 800. The charging component is mounted on a support frame 200, and at least a portion of the charging component is located within a ventilation space 110. When air circulates within the ventilation space 110, it can exchange heat with at least a portion of the charging component, thus achieving a cooling effect. The device 800 may include a mobile phone, tablet computer, etc.

[0063] In some embodiments, such as Figure 1 , Figure 2As shown, the charging assembly includes a circuit board 500 and a charging coil 600.

[0064] In some embodiments, the charging coil 600 is disposed on one side of the support frame 200 facing the housing 300.

[0065] The charging coil 600 is used to charge the device 800 to be charged. In some embodiments, the charging coil 600 may include a wireless charging coil, etc.

[0066] In some embodiments, such as Figure 6 As shown, the support frame 200 is provided with a limiting protrusion 230, which is used to limit the relative position of the charging coil 600 and the support frame 200. In some embodiments, the limiting protrusion 230 can be annular or at least part of an annular shape, and the charging coil 600 is disposed inside the limiting protrusion 230. In some embodiments, the inner surface of the limiting protrusion 230 is connected to at least part of the outer surface of the charging coil 600, thereby limiting the circumferential position of the charging coil 600 by the limiting protrusion 230, which is beneficial to further improve the positional accuracy of the charging coil 600.

[0067] In some embodiments, the charging coil 600 can be connected to the support frame 200 in a variety of ways, such as at least one of adhesive bonding, snap-fitting, threaded connection, welding, etc.

[0068] In some embodiments, the faceplate 300 has a second mounting groove, and the charging coil 600 is disposed in the second mounting groove.

[0069] The second mounting slot and the support frame 200 enclose a space for mounting the charging coil 600, providing sufficient space inside the housing assembly for mounting the charging coil 600. In some embodiments, the charging coil 600 can contact the faceplate 300, and some of the heat generated by the charging coil 600 during operation can be conducted to the faceplate 300. The air circulating in the first ventilation channel can exchange heat with the faceplate 300, resulting in a cooling effect. Another portion of the heat can be conducted to the support frame 200, and the air circulating in the ventilation space 110 can exchange heat with the support frame 200, resulting in a cooling effect.

[0070] In some embodiments, such as Figure 2 , Figure 5 As shown, the circuit board 500 is disposed on the side of the support frame 200 away from the front cover 300 and located within the ventilation space 110. The air circulating within the ventilation space 110 can dissipate heat from the circuit board 500.

[0071] Circuit board 500 is used to integrate electronic components and circuits.

[0072] In some embodiments, such as Figure 9As shown, the circuit board 500 is located on the side of the support frame 200 facing the base 100, and the control module 510 and the circuit 520 are provided on the circuit board 500.

[0073] The control module 510 is used at least to analyze, process, and store data, and can also be used to store and execute preset programs, and issue control commands to other structures. In some embodiments, the control module 510 may include various modules, such as a microprocessor, a control chip, etc.

[0074] Circuit 520 is used to transmit electrical signals.

[0075] In some embodiments, the airflow driver 400 and the charging coil 600 are electrically connected to the circuit board 500.

[0076] In some embodiments, the control module 510 can be connected to the airflow driver 400 and the charging coil 600 via the circuit 520. The connection may include an electrical connection and / or a communication connection. The control module 510 can control the airflow driver 400 and the charging coil 600 respectively, for example, controlling the airflow driver 400 and the charging coil 600 to perform functions such as starting, stopping, and changing the operating power.

[0077] The multi-channel heat dissipation charging device provided in some embodiments of this specification, by forming a first ventilation channel and a third ventilation channel, can simultaneously dissipate heat from different structures inside the multi-channel heat dissipation charging device, thereby improving heat dissipation efficiency. Allowing cool air to circulate separately within the first and second ventilation channels enables simultaneous heat exchange between corresponding structures within the two channels, improving the utilization rate of cool air and thus enhancing heat dissipation efficiency. Simultaneously, the air circulating in the first ventilation channel can contact the device to be charged, thereby also dissipating heat from the device. The first, second, and third ventilation channels are isolated from each other, preventing airflow obstruction caused by the impact between the air entering and exiting the multi-channel heat dissipation charging device, thus increasing airflow speed and improving heat dissipation efficiency.

[0078] In some embodiments, such as Figure 6 As shown, the support frame 200 includes a support plate 201 and a support column 260.

[0079] The support plate 201 is a plate-shaped structure and serves as the installation base for mounting the support column 260.

[0080] In some embodiments, the airflow driver 400 is disposed on the support plate 201, and the charging coil 600 is disposed around the airflow driver 400 between the support plate 201 and the faceplate 300.

[0081] In some embodiments, such as Figure 6 As shown, the support column 260 is located on the side of the support plate 201 away from the face shell 300; the circuit board 500 is connected to the support column 260 facing the support plate 201, so as to form a gap between the support plate 260 and the circuit board 500.

[0082] Support posts 260 are used to connect to the circuit board 500 to improve the stability of the circuit board 500 and limit the distance between the circuit board 500 and the support frame 200. In some embodiments, multiple support posts 260 may be arranged in a ring around the circumference of the support frame 200. Simultaneous connection of multiple support posts 260 to the circuit board 500 can prevent the circuit board 500 from forming a cantilever structure, which would lead to decreased stability. In some embodiments, the support posts 260 and the circuit board 500 can be connected in various ways, such as at least one of snap-fit, welding, and threaded connection.

[0083] In some embodiments, the gap formed between the support plate 260 and the circuit board 500 allows air in the ventilation space 110 to enter the airflow driver 400 through the gap. When the air flows in the ventilation space 110, it can make full contact with both sides of the circuit board 500, thereby improving the efficiency of cooling the circuit board.

[0084] In some embodiments, placing the charging coil 600 close to the housing 300 can reduce the distance between the charging coil 600 and the charging device 800, thereby improving charging efficiency. Placing the circuit board 500 away from the housing 300 and within the ventilation space 110 can increase the size of the space occupied by the circuit board 500, thereby enhancing the heat dissipation effect on the components in the circuit board 500.

[0085] In some embodiments, such as Figure 5 , Figure 6 As shown, the support frame 200 has a first mounting groove 220 and an air duct 210. The airflow actuator 400 is disposed within the first mounting groove 220.

[0086] In some embodiments, the opening of the first mounting groove 220 is formed on the side of the support plate 201 facing the face shell 300. The bottom of the first mounting groove 220 protrudes from the side of the support plate 201 facing the base 100. In some embodiments, the fourth vent 410 of the airflow driver 400 faces the same direction as the opening of the first mounting groove 220, and the first mounting groove 220 has a through hole communicating with the fifth vent 420.

[0087] In some embodiments, the first mounting groove 220 is provided with at least one first positioning step 250, and the airflow driver 400 has at least one second positioning step 440. The first positioning step 250 and the second positioning step 440 are adapted to each other. By connecting the first positioning step 250 and the second positioning step 440, the positioning accuracy of the airflow driver 400 in the first mounting groove 220 can be improved.

[0088] In some embodiments, the airflow actuator 400 can be installed in the first mounting slot 220 in a variety of ways, such as welding, snap-fitting, threaded connection, etc., thereby improving the connection strength between the airflow actuator 400 and the first mounting slot 220 and the stability of the airflow actuator 400, and reducing the noise generated by the airflow actuator 400 during operation.

[0089] In some embodiments, the base 100 has a support structure for supporting the support frame 200. The support structure may include a variety of elements, such as at least one of a stepped surface, a pillar, or a pad. In some embodiments, a buffer structure, such as a rubber pad, may be provided between the support structure and the support frame 200 to buffer and reduce vibration, thereby reducing the noise generated when the airflow drive 400 is running.

[0090] The air duct 210 is used to guide the flow direction of air in the second ventilation channel, for example, to guide air to flow to the outside of the housing assembly, or to flow from the outside of the housing assembly to the inside.

[0091] In some embodiments, the air duct 210 connects the sixth vent 430 and the third vent 130 to form a second ventilation channel. Air entering the airflow actuator 400 can be exhausted to the outside of the housing assembly through the second ventilation channel. Alternatively, air can flow from the outside of the housing assembly into the airflow actuator 400 through the second ventilation channel.

[0092] In some embodiments, the air duct 210 is disposed on the side of the support frame 200 facing the ventilation space 110 and communicates with the interior of the first mounting groove 220. This allows the air duct 210 to come into contact with the cold air in the ventilation space 110. When the air duct 210 is heated by the exhaust hot air, the cold air in the ventilation space 110 can be used to cool the air duct 210.

[0093] In some embodiments, the sixth vent 430 of the airflow actuator 400 can be sealed to the air duct 210 to prevent gaps from forming between the sixth vent 430 and the air duct 210, which would cause air to escape from the gaps and impact the air in the ventilation space 110, resulting in turbulence. This helps to ensure the stability of airflow and heat dissipation efficiency. The shape of the air duct 210 can be adapted to the sixth vent 430.

[0094] In some embodiments, the air duct 210 and the support frame 200 can be connected in a variety of ways, such as at least one of adhesive bonding, snap-fitting, threaded connection, integral molding, etc.

[0095] The air duct 210 can isolate the second ventilation channel from the first and third ventilation channels, preventing the air in the second, first and third ventilation channels from impacting each other and affecting the smooth flow of air, thereby ensuring the heat dissipation effect.

[0096] In some embodiments, such as Figure 5 As shown, the support plate 200 also has a mounting port 270, which is disposed through the channel wall of the air duct 210. At least part of the circuit board 500 covers the mounting port 270 or extends into the air duct 210 through the mounting port 270.

[0097] In some embodiments, components in the circuit board 500 that generate significant heat can have their mounting opening 270 covered or extend into the air duct 210 through the mounting opening 270. For example, a control module 510. Part of the heat from these components can be directly discharged from the air duct 210 and the third vent 130 with the airflow, while another part can be conducted to the circuit board 500. The air in the ventilation space 110 cools the circuit board 500. After heat exchange, the air exits from the sixth vent 430 of the airflow driver 400 and enters the air duct 210, where it can further exchange heat with the components that generate significant heat. This further reduces the temperature of the components, allowing them to cool down quickly and preventing heat buildup inside the housing assembly from affecting the normal operation of other components.

[0098] The multi-channel heat dissipation charging device provided in some embodiments of this specification, by setting a support frame 200, can divide the internal accommodating space of the housing assembly into layers, and use it as a mounting base to install the internal structure in layers, thereby improving the utilization rate of the internal space of the multi-channel heat dissipation charging device, and also facilitating the planning of the airflow direction, avoiding mutual interference of airflow in the second ventilation channel, the first ventilation channel and the third ventilation channel.

[0099] In some embodiments, such as Figure 9 As shown, the charging assembly also includes a temperature detection element 540. The temperature detection element 540 is disposed inside the housing and electrically connected to the circuit board 500.

[0100] Temperature detection element 540 is used to detect the temperature of charging coil 600 and / or device 800 to be charged. In some embodiments, temperature detection element 540 may include a temperature sensor. In some embodiments, circuit board 500 is configured to control airflow driver 400 based on temperature information acquired by temperature detection element 540.

[0101] In some embodiments, when the temperature of the charging coil 600 and / or the device to be charged 800 obtained by the temperature detection element 540 is within a preset temperature range, the circuit board 500 can control the airflow driver 400 to operate with the corresponding operating parameters.

[0102] As an example only, when the temperature of the charging coil 600 and / or the device 800 to be charged is greater than 45°C, the fan in the airflow driver 400 rotates at its maximum speed. When the temperature of the charging coil 600 and / or the device 800 to be charged is between 35°C and 45°C, the fan in the airflow driver 400 rotates at 50% of its maximum speed. When the temperature of the charging coil 600 and / or the device 800 to be charged is less than 35°C, the fan in the airflow driver 400 stops working. The temperature range, operating parameters, and the correspondence between temperature ranges and operating parameters can be preset values ​​and can be determined in various ways, such as based on experience or according to actual needs.

[0103] In some embodiments, the temperature sensing element 540 may contact the charging coil 600. In some embodiments, such as Figure 6 As shown, the support frame 200 is provided with a clearance opening 240. The wiring connecting the temperature sensing element 540 and the circuit board 500 can pass through the clearance opening 240 to connect to the circuit board 500, thereby avoiding interference. In some embodiments, such as Figure 4 As shown, the side of the housing 300 facing the charging coil 600 has a clearance groove 340, within which the temperature sensing element 540 can be located to prevent damage from pressure. The side of the clearance groove 340 facing away from the charging coil 600 can protrude outwards from the surface of the housing 300 and connect with one of the support protrusions 330. This outward protrusion of the side of the clearance groove facing away from the charging coil 600 ensures sufficient thickness at the location of the clearance groove 340, thus guaranteeing the strength of that location and preventing damage from pressure.

[0104] In some embodiments, such as Figure 9 As shown, the charging assembly also includes a connection port 530. The control module 510 is connected to the connection port 530 and the temperature sensor 540 via a circuit 520. The connections may include electrical connections and / or communication connections.

[0105] The connector 530 is configured to connect to an external power source, for example, via a charging cable.

[0106] In some embodiments, the wiring port 530 is located on the circuit board 500, and the wiring port 530 can be electrically connected to the circuit 520. In some embodiments, such as Figure 3 As shown, the base 100 is provided with a wiring hole 140, and the wiring port 530 can be snapped into the wiring hole 140. The wiring hole 140 can be used to restrict the position of the wiring port 530 and improve the stability of the wiring port 530.

[0107] In some embodiments, such as Figure 8 As shown, in the arrangement direction of the faceplate 300 and the base 100 (e.g., Figure 8 In the X direction (as shown in the diagram), the geometric center line of the third vent 130 is inclined towards the side away from the housing 300. The third vent 130 can change the airflow direction, allowing the hot air exhausted through the third vent 130 to flow outward in a direction away from the device to be charged 800, preventing the hot air after heat exchange from being drawn back into the housing assembly by the airflow driver 400 from the first vent, thus affecting the heat dissipation effect. At the same time, it can also prevent the hot air exhausted from the third vent 130 from blowing directly onto the device to be charged 800, causing the temperature of the device to be charged 800 to rise, or from affecting the heat dissipation effect of the device to be charged 800.

[0108] In some embodiments, such as Figure 4 As shown, the housing 300 has multiple exposed support bosses 330, which are arranged at intervals around the first vent 310. The support bosses 330 support the device 800 to be charged, forming a third air intake channel 320 connecting the housing 300 and the device 800 to the first vent 310. When the airflow actuator 400 is working, it can draw in external air through the third air intake channel 320. During the airflow within the third air intake channel 320, heat exchange can occur between the airflow actuator 400 and the housing 300 and the device 800. The multiple support bosses 330 arranged around the first vent 310 can form multiple third air intake channels 320 around the circumference of the housing 300. When the airflow actuator 400 is working, it can make the air outside the housing 300 enter the first vent 310 evenly from the circumference of the housing 300 through the third air intake channels 320, which helps to avoid turbulence. At the same time, it can also increase the contact area between the flowing air and the device 800 to be charged, and dissipate heat from different directions, which is conducive to improving the heat dissipation efficiency and effect of the device 800 to be charged.

[0109] In some embodiments, the surface of the support boss 330 facing the device 800 to be charged may be provided with an anti-slip structure, such as an anti-slip pattern, a rubber pad layer, etc.

[0110] In some embodiments, the side of the support boss 330 may be spiral-shaped to reduce resistance to airflow.

[0111] In some embodiments, the multi-channel heat dissipation charging device further includes an air guide shroud 350 and / or a magnetic element 700.

[0112] An air guide hood is installed inside the first ventilation opening 310 to guide airflow through the third air inlet channel 320 into the first ventilation channel.

[0113] The air guide shroud 350 is used to control the direction of airflow from the third air inlet channel 320 to the first vent 310. In some embodiments, an annular gap may be formed between the lower surface of the air guide shroud 350 and the inner surface of the first vent 310. This annular gap guides airflow, preventing turbulence and thus reducing noise and improving airflow efficiency. In some embodiments, the side of the air guide shroud 350 facing the first vent 310 may be a conical surface.

[0114] In some embodiments, a connecting bracket may be provided within the first vent 310, and the air guide shroud 350 may be mounted using the connecting bracket as a mounting base. The connecting bracket may include various shapes, such as a straight line, a three-pronged shape, a cross shape, etc.

[0115] In some embodiments, the air guide shroud 350 may also adopt other structures, such as a mesh structure, a porous structure, etc.

[0116] In some embodiments, the magnetic member 700 is disposed on the face shell 300 and / or the support frame 200 for attaching and fixing the device 800 to be charged onto the face shell 300.

[0117] The magnetic attractor 700 is used to magnetically connect with the device 800 to be charged, thereby improving the stability of the device 800. In some embodiments, one magnetic attractor 700 may be provided, and the magnetic attractor 700 may be annular or at least part of an annular shape. The magnetic attractor 700 may be located outside the limiting protrusion 230, and the limiting protrusion 230 may be used to limit the position of the magnetic attractor 700, thereby improving the positional accuracy of the magnetic attractor 700.

[0118] In some embodiments, multiple magnetic suction elements 700 may be provided, and the multiple magnetic suction elements 700 may be distributed in a ring on the outer side of the limiting protrusion 230. In some embodiments, the magnetic suction elements 700 and the face shell 300 may be connected in various ways, such as adhesive bonding, snap-fit ​​bonding, etc.

[0119] This utility model also provides a charging device housing, the structure of which is the same as that described in any of the above embodiments, and will not be repeated here. Furthermore, this housing can be applied not only to the charging devices described in the above embodiments, but also to other types of charging devices.
