Detailed implementation manners

[0050] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0051] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present invention. Therefore, only the components related to the present invention are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0052] Please refer to Figures 1 to 11 As shown, the present invention provides a charging device to solve the problems that the structure or layout of the heat dissipation air duct of the existing device may limit the heat dissipation efficiency, unable to meet the heat dissipation requirements, and the water accumulation problem caused by limited waterproof effect. Specifically, the charging device 100 includes a housing 10, a charger heat dissipation structure, and a battery pack heat dissipation structure. The housing 10 serves as the basic structure of the entire device, and a charging slot is formed inside. The charging slot is configured with a first charging interface 102 for cooperating with the battery pack 200 to achieve power transmission. To solve the problem of low heat dissipation efficiency of the existing charging device, the present invention specially designs an independent charger heat dissipation structure and a battery pack heat dissipation structure to avoid heat interference with each other, improve the heat dissipation efficiency, ensure rapid heat dissipation, and prevent the device from overheating.

[0053] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, in this embodiment, the charger heat dissipation structure includes an air inlet component 21, an air outlet component 22, and a first cooling fan 23. Both the air inlet component 21 and the air outlet component 22 are provided on the side surface of the housing 10. Preferably, both the air inlet component 21 and the air outlet component 22 are provided on two opposite side surfaces of the housing 10 to better form air convection and promote heat dissipation. The first cooling fan 23 is installed inside the housing 10, near the air inlet component 21 and the air outlet component 22, to enhance air flow and accelerate heat dissipation. This design can effectively reduce the internal temperature of the device and ensure the stable operation of the charging device under high load.

[0054] Please refer to Figure 2 、 Figure 3 、 Figure 6 and Figure 7As shown, in this embodiment, the structures of the air inlet component 21 and the air outlet component 22 are optimized. Both adopt a wind window structure. This design not only enhances the efficiency of air circulation but also effectively prevents foreign objects from entering the interior of the device. In particular, for the air inlet component 21, it is detachably connected to the housing 10. This design allows users to easily disassemble the air inlet component 21 during daily maintenance for cleaning or replacing the filter material. The detachable connection improves the maintenance convenience of the device and extends its service life.

[0055] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, a filter structure is added to the wind window structure of the air inlet component 21. For example, the air inlet component 21 is designed as a filter mesh structure. The filter structure can effectively filter dust, impurities, and particulate matter in the air, preventing them from entering the interior of the device and avoiding a reduction in heat dissipation efficiency or device failure caused by dust accumulation. The design of the filter structure particularly considers the balance between filtration effect and air resistance to ensure that while achieving high-efficiency filtration, it does not cause excessive obstruction to air flow, thus ensuring the normal operation of the heat dissipation system. Further, the air inlet component 21 is detachably connected to the housing 10. This design allows users to easily disassemble the air inlet component 21 during daily maintenance for cleaning or replacing the filter material.

[0056] Please refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in this embodiment, the wind window structure includes a wind window body 211, a detachable bolt 212, and a limiting member 213. The wind window body 211 is installed on the side of the housing 10 and can be connected, for example, by a snap-fit method to provide initial fixation. The detachable bolt 212 passes through the wind window body 211 and is threadedly connected to the housing 10 to further enhance the fixation effect and ensure the stability of the wind window structure. The limiting member 213 is installed on the detachable bolt 212 and is located on the side of the wind window body 211 facing the interior of the housing 10 to prevent the bolt from being lost or falling off after disassembly, improving the usability and maintenance efficiency of the device. The limiting member 213 can be set as a circlip, an R-shaped spring, a retaining pin, an elastic O-ring, or a part that can hold the screw.

[0057] Please refer to Figure 2As shown, in this embodiment, the housing 10 is designed as a split structure, including an upper housing 11 and a lower housing 12. The first charging interface 102 is located on the outer surface of the upper housing 11, facilitating the installation and charging operation of the battery pack 200. The air duct assembly 32 is fixed to the upper housing 11 to ensure the stability and reliability of the heat dissipation air duct. The split housing design not only facilitates the assembly and disassembly of the device but also enables the maintenance and repair of the internal structure. In addition, the sealing treatment between the upper housing 11 and the lower housing 12 further enhances the waterproof performance of the device, enabling it to operate stably in a humid environment.

[0058] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, a water baffle 121 is added inside the lower housing 12. The water baffle 121 is arranged opposite to the first side surface provided with the air inlet assembly 21 and the air outlet assembly 22, forming a waterproof barrier. When the device is splashed with water or in a humid environment, the water baffle 121 can effectively block the moisture from entering the device interior and protect the internal electronic components from damage. This design significantly enhances the waterproof performance of the device and adapts to various complex usage environments.

[0059] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, a first drain hole 122 is provided on the lower housing 12, and its position is between the water baffle 121 and the first side surface. The design of the first drain hole 122 is used to timely drain the liquid that may enter the device interior, prevent the liquid from accumulating inside the device to form ponding, and thus avoid device short - circuit or other failures caused by ponding. The size and position of the first drain hole 122 are carefully designed to balance the drainage efficiency and waterproof performance, ensuring the normal operation of the device during the drainage process. It can be understood that the design of the water baffle 121 and the first drain hole 122 enhances the waterproof and anti - ponding capabilities of the device. First, the water baffle 121 is arranged inside the housing 10, opposite to the side where the air inlet assembly 21 and the air outlet assembly 22 are located, effectively preventing moisture from entering the device interior, and the setting of the first drain hole 122 can drain the liquid entering from the air inlet assembly 21 and the air outlet assembly 22, effectively preventing ponding.

[0060] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, in this embodiment, the charger heat dissipation structure includes two first cooling fans 23, which are arranged inside the housing 10 and are respectively located near the air inlet assembly 21 and the air outlet assembly 22 to enhance air flow and accelerate heat dissipation.

[0061] Please refer to Figure 2 , Figure 5 , Figures 7 to 10As shown in the figure, in this embodiment, the battery pack heat dissipation structure includes a heat dissipation air vent 31, an air duct assembly 32, and a second heat dissipation fan 33. The heat dissipation air vent 31 is provided on the first charging interface 102 and is in direct contact with the battery pack 200 to quickly conduct the heat generated by the battery pack. The air duct assembly 32 is installed inside the housing 10 and is isolated from the internal space of the housing 10 to form an independent heat dissipation channel. The air inlet of the air duct assembly 32 corresponds to the heat dissipation air vent 31, and the air outlet 301 is arranged on the side of the housing 10 to ensure that the heat can be efficiently discharged. The second heat dissipation fan 33 is installed inside the air duct assembly 32 and is specifically used for the heat dissipation of the battery pack to prevent the battery pack from being affected in performance or causing potential safety hazards due to excessive temperature during charging. It can be understood that the charger heat dissipation structure and the battery pack heat dissipation structure are isolated from each other through the air duct assembly 32 to avoid heat interference with each other, improve the heat dissipation efficiency, and the first heat dissipation fan 23 and the second heat dissipation fan 33 are respectively responsible for the heat dissipation of the charger and the battery pack to ensure that the heat is quickly discharged and prevent the device from overheating.

[0062] Please refer to Figure 2 , Figure 3 , Figure 5 , Figures 7 to 10 As shown in the figure, in this embodiment, the air inlets of the air inlet assembly 21 and the air duct assembly 32 and the air outlet 301 are respectively arranged on adjacent side walls of the housing 10. The housing 10 includes a first side wall 111, a second side wall 112, a third side wall 113, and a fourth side wall 114. The first side wall 111 and the second side wall 112 face away from each other, and the third side wall 113 and the fourth side wall 114 face away from each other. Among them, the air inlet assembly 21 is arranged on the first side wall 111, the air outlet assembly 22 is arranged on the second side wall 112, the battery pack 200 is inserted into the charging slot in the direction from the third side wall 113 to the fourth side wall 114 for charging, and the air outlet 301 of the air duct assembly 32 is arranged on the fourth side wall 114. The air duct assembly 32 is arranged between the air inlet assembly 21 and the air outlet assembly 22 so that the air flow between the air inlet assembly 21 and the air outlet assembly 22 passes through the air duct assembly 32. Specifically, the air flow of the charger heat dissipation structure only enters the interior of the housing 10 through the air inlet assembly 21 and is discharged from the air outlet assembly 22 after passing through the outer circumference or outer wall of the air duct assembly 32.

[0063] Please refer to Figure 11 As shown in the figure, in this embodiment, the air-cooling path of the battery pack is as follows: When the battery pack 200 is installed on the charging device 100 and the second heat dissipation fan 33 is started, air enters the interior of the battery pack 200 from the side of the battery pack 200 (for example, the side facing away from the first charging interface 102), and after flowing out from the side of the battery pack 200 facing the first charging interface 102, it enters the air duct assembly 32 through the heat dissipation air vent 31 and is then discharged, thereby taking away the heat of the battery pack 200.

[0064] Please refer to Figure 7 ,Figure 8 , Figure 9 and Figure 10 As shown in Figure 10 , in this embodiment, the air duct assembly 32 includes a fan cover 321, a gasket 322, and a wind cover pressing plate 323. The fan cover 321 is installed inside the housing 10 and fixedly connected to the upper housing 11, providing a stable installation position for the second cooling fan 33. The gasket 322 is disposed between the second cooling fan 33 and the upper housing 11 and arranged around the heat dissipation air outlet 31 to ensure the airtightness of the air duct and prevent heat leakage. The wind cover pressing plate 323 is fixedly connected to the fan cover 321 to form an independent air duct, which is hermetically isolated from the internal space of the housing 10 to avoid interference between heat and air flow and improve the heat dissipation efficiency. A gasket 322 is designed to be arranged around the heat dissipation air outlet 31 between the second cooling fan 33 and the upper housing 11 to ensure the airtightness of the air duct, prevent heat leakage, hermetically isolate the air duct assembly 32 from the internal space of the housing 10, avoid interference between heat and air flow, and improve the heat dissipation efficiency; at the same time, the gasket 322 can also act as a shock-absorbing pad to play a role in shock absorption and buffering to protect the battery pack heat dissipation structure.

[0065] Please refer to Figure 2 , Figure 4 and Figure 5 As shown in Figure 5 , the structure of the first charging interface 102 is optimized in this embodiment and divided into a first area 1021 and a second area 1022. The heat dissipation air outlet 31 is arranged in the first area 1021, and this area is higher than the second area 1022. This design helps to prevent moisture from accumulating at the heat dissipation air outlet 31 and avoid risks such as equipment short circuits or other failures caused by water accumulation. When the device is in a humid environment or splashed with water, the higher first area 1021 can effectively guide the moisture to flow to the second area 1022 and drain it out of the device through the drain hole.

[0066] Please refer to Figure 2 , Figure 4 and Figure 5 As shown in Figure 5 , in this embodiment, the charging slot is further configured with a second charging interface 103 for installing the charging terminal 40. The first charging interface 102 extends obliquely downward along the first direction X, and the first direction X is the direction towards the second charging interface 103. This design optimizes the internal space layout of the charging slot, enabling the battery pack 200 to contact the charging interface more stably during the installation process. The obliquely extending first charging interface 102 not only improves the convenience and accuracy of the charging operation but also helps to guide the water flow direction, reduce the accumulation of moisture at the charging interface, and improve the waterproof performance of the device.

[0067] Please refer to Figure 2 , Figure 4 and Figure 5As shown, at least one second drainage hole 104 is provided at a position of the first charging interface 102 close to the second charging interface 103. The second drainage hole 104 penetrates through the housing 10 and is isolated from the internal space of the housing 10. This design is used to timely drain the liquid that may accumulate in the charging slot, prevent moisture from accumulating at the charging port or inside, so as to avoid equipment short - circuit or other failures caused by water accumulation. The position and size of the second drainage hole 104 are carefully designed to ensure that it will not interfere with the charging operation during the drainage process, and at the same time ensure the timeliness and effectiveness of drainage.

[0068] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the structure of the second charging interface 103 is optimized and divided into a third area 1031 and a fourth area 1032. The third area 1031 is the area for installing the charging terminal 40, and the third area 1031 is higher than the fourth area 1032. This design helps to prevent moisture from accumulating at the charging terminal 40 and improves the waterproof performance of the charging interface. When the device is in a humid environment or splashed with water, the higher third area 1031 can guide the moisture to flow to the lower fourth area 1032 and be discharged outside the device through corresponding drainage measures, ensuring the dryness and safety of the charging terminal 40. Further, the fourth area 1032 extends obliquely downward along the second direction Y, and the second direction Y is the direction away from the first charging interface 102. This design further optimizes the water flow guidance inside the charging slot, so that when the device is splashed with water or in a humid environment, the moisture can be discharged outside the device along the obliquely extending fourth area 1032. Through such a structural design, the residence time of moisture inside the charging slot is effectively reduced, the risk of equipment failure caused by water accumulation is reduced, and the overall waterproof performance and use reliability of the device are improved. It can be understood that the heat dissipation air outlet 31 area in the first charging interface 102 is higher than other areas, the third area of the second charging interface 103 is higher than the fourth area, both of which help to prevent moisture accumulation, and the second drainage hole can help drain the accumulated water to prevent moisture from accumulating at the charging port or inside.

[0069] Please refer to Figures 1 to Figure 11As shown in the figure, this embodiment provides a charging device that supports charging multiple devices. The charging slot is configured with a plurality of first charging interfaces 102, and each first charging interface 102 is cooperatively installed with a battery pack 200 and a set of battery pack heat dissipation structures. Such a design enables the charging device to charge multiple battery packs 200 simultaneously, and each battery pack 200 is equipped with an independent heat dissipation structure to ensure that the heat dissipation requirements of each battery pack 200 are met under the condition of charging multiple devices. Through the reasonable layout of the plurality of first charging interfaces 102 and their corresponding heat dissipation structures, the device realizes an efficient multi-device charging function within a limited space, improves the usage efficiency and application scope of the device, and meets the charging needs of users in different scenarios.

[0070] The present invention proposes a charging device. Through an independent heat dissipation design, the heat dissipation efficiency is improved. First, the charger heat dissipation structure and the battery pack heat dissipation structure are isolated from each other through an air duct assembly to avoid heat interference and enhance the heat dissipation efficiency. Second, the first cooling fan and the second cooling fan are respectively responsible for the heat dissipation of the charger and the battery pack to ensure that heat is quickly discharged and prevent the device from overheating.

[0071] The present invention proposes a charging device. The waterproof and anti-pooling capabilities of the device are enhanced through the design of a water baffle and drain holes. First, the water baffle is arranged inside the housing and is opposite to the side where the air inlet assembly and the air outlet assembly are located, effectively preventing moisture from entering the device interior. And the setting of the first drain hole can drain the liquid entering from the air inlet assembly and the air outlet assembly, effectively preventing water accumulation. Second, the heat dissipation air outlet area in the first charging interface is higher than other areas, and the third area of the second charging interface is higher than the fourth area, both of which help prevent water accumulation. And the second drain hole can help drain the accumulated water to prevent moisture from accumulating at the charging port or inside.

[0072] The present invention proposes a charging device, in which the air inlet assembly and the air outlet assembly adopt a wind window structure, and the air inlet assembly is detachably connected to the housing. Users can perform cleaning and maintenance through manual operation. A limiting member is arranged on the detachable bolt to prevent the bolt from falling off or getting lost after disassembly, improving the maintenance convenience. The wind window structure of the air inlet assembly is provided with a filtering structure to prevent dust from entering the device interior and reduce the maintenance frequency.

[0073] The present invention proposes a charging device. By designing a sealing gasket between the second cooling fan and the upper housing and arranging it around the heat dissipation air outlet, the air duct is ensured to be sealed to prevent heat leakage, so that the air duct assembly is sealed and isolated from the interior space of the housing, avoiding heat and air flow interference and enhancing the heat dissipation efficiency.
