[0052] [First Embodiment]

[0053] Referring to Figures 1 to 3, the first embodiment of this application provides a charging device 100, which may specifically include, for example, a housing 1, a partition structure 2, and multiple heat source electrical components.

[0054] The outer casing 1 is the outer casing of the charging device 100, and the outer casing 1 has a receiving cavity. A partition structure 2 is disposed within the outer casing 1, and the partition structure 2 divides the receiving cavity into multiple partitioned areas. The partition structure 2 can, for example, be fixedly connected to the outer casing 1. Multiple heat source electrical devices are respectively disposed within the multiple partitioned areas, and the number of partitioned areas can be set, for example, according to the needs of the heat source electrical devices. By setting the partition structure 2, the multiple heat source electrical devices are arranged in separate areas, thereby enabling uniform heat source distribution, and the partition structure 2 can also separate the heat sources.

[0055] The charging device 100 provided in this embodiment provides a partition structure 2 inside the outer shell 1. The partition structure 2 divides the accommodating cavity inside the outer shell 1 into multiple partition areas, and multiple heat source electrical components are respectively placed in multiple partition areas. Thus, the multiple heat source electrical components are separated by the partition structure 2 and are evenly distributed in the accommodating cavity, thereby achieving the effect of uniform distribution of heat sources inside the charging device 100, thereby improving heat dissipation efficiency and ensuring the safety and performance of the charging device.

[0056] Furthermore, in one embodiment of this invention, the multiple heat source electrical devices may include, for example, multiple charging circuit boards and multiple electronic components, with the electronic components disposed on the charging circuit boards. In another embodiment of this invention, the multiple heat source electrical devices may include, for example, multiple charging circuit boards, multiple electronic components, and a battery, with the electronic components disposed on the charging circuit boards. By distributing the electronic components on multiple charging circuit boards and distributing the charging circuit boards in multiple partitioned areas, the distribution of the heat source devices within the accommodating cavity is made relatively uniform, thereby achieving a better and more uniform heat dissipation effect. In this embodiment, the heat source electrical devices refer to electronic devices that generate a large amount of heat inside the charging device 100 when it is working, and not to electrical devices used as heat sources.

[0057] In this embodiment, the charging device 100 may be, for example, a power bank, a power adapter, or a multi-functional charging device that combines the functions of a charger and a power bank. The charging device 100 of this embodiment will be specifically described below using a power bank with a charger function as an example.

[0058] Referring again to Figures 2 to 7, the multiple partitioned regions may include, for example, a high-pressure heat insulation cavity 210 and a low-pressure heat insulation cavity 220, which are arranged, for example, along the length of the charging device 100. Multiple heat source electrical components include high-voltage and low-voltage components, with the high-voltage components housed within the high-pressure heat insulation cavity 210 and the low-voltage components housed within the low-pressure heat insulation cavity 220. The charging circuit typically includes an AC-to-DC circuit module and a DC-to-DC circuit module, with the high-voltage components being, for example, electronic components in the AC-to-DC circuit module, and the low-voltage components being, for example, electronic components in the DC-to-DC circuit module.

[0059] The partition structure 2 may include, for example, a high-voltage partition 21 and a low-voltage partition 22. The high-voltage partition 21 forms a high-voltage heat insulation cavity 210, and the low-voltage partition 22 forms a low-voltage heat insulation cavity 220. Through the high-voltage partition 21 and the low-voltage partition 22, multiple heat source electrical devices can be separated by the partition structure 2, resulting in a uniform distribution of the multiple heat source electrical devices. Furthermore, the high-voltage and low-voltage electrical devices can be set separately, thereby further avoiding mutual interference between the high-voltage and low-voltage electrical devices, further improving the uniform heat dissipation effect, and enhancing the safety and performance of the charging device 100. In this embodiment, the low-voltage electrical device may include, for example, a battery 35, which is disposed in the low-voltage heat insulation cavity 220.

[0060] Further, in one embodiment of this example, the high-voltage separator 21 and the low-voltage separator 22 are arranged sequentially along the length of the housing 1. The high-voltage separator 21 and the low-voltage separator 22 are preferably made of an insulating material with low thermal conductivity. This arrangement reduces the heat transfer area between the high-voltage and low-voltage electrical components, thereby further reducing the influence between them. Referring again to Figures 2 and 3, the housing 1 includes a first housing 11 and a second housing 12 arranged opposite each other along the length direction, and a third housing 13 and a fourth housing 14 arranged opposite each other along the thickness direction. The first housing 11, the second housing 12, the third housing 13, and the fourth housing 14 together form a receiving cavity. The high-voltage separator 21 is disposed on the side closer to the first housing 11, and the low-voltage separator 22 is disposed on the side closer to the second housing 12. The charging device 100 may, for example, further include: a plug 41 and a charging interface 50, with the plug 41 disposed on the first housing 11 and the charging interface 50 disposed on the second housing 12.

[0061] Referring to Figures 4 and 5, in one embodiment of this invention, the high-pressure separator 21 includes a first partition 211 and a second partition 212 disposed opposite to each other, with the first partition 211 disposed close to the first housing 11. The first partition 211 and the second partition 212 are, for example, heat-insulating plates or components with heat-insulating functions, such that a high-pressure heat-insulating cavity 210 is formed between the first partition 211 and the second partition 212. In another embodiment of this invention, the high-pressure separator 21 includes a second partition 212, with a high-pressure heat-insulating cavity 210 formed between the second partition 212 and the first housing 11.

[0062] Referring to Figures 6 and 7, the low-voltage separator 22 includes a third separator 221, which is disposed close to the second separator 212. The third separator 221 is, for example, a heat insulation plate or a component with heat insulation function. The third separator 221 and the second housing 12 form a low-voltage heat insulation cavity 220. Through the arrangement of the heat insulation plate, the heat insulation plate and the housing can form a separated heat insulation cavity. In one embodiment of this example, the third separator 221 and the second separator 212 can be, for example, separately disposed, or the third separator 221 and the second separator 212 can also be, for example, an integrally formed structure. In one embodiment of this example, the third separator 221 and the second separator 212 are in contact, or the third separator 221 and the second separator 212 are spaced apart. Through the adjacent arrangement of the second separator 212 and the third separator 221, and through the superposition of the thicknesses of the second separator 212 and the third separator 221, the spacing between the high-voltage circuit board and the low-voltage circuit board can be further increased. In some embodiments, in order to further reduce the length of the charging device 100, only the third partition 221 may be provided, while the second partition 212 may be omitted, and the third partition 221 may be used to achieve the function of insulation or heat insulation.

[0063] Referring again to Figures 4 and 5, the high-voltage separator 21 may, for example, further include a fourth separator 213. The fourth separator 213 is connected between the first separator 211 and the second separator 212, and divides the high-voltage heat insulation cavity 210 into a first mounting position 201 and a second mounting position 202. Similarly, the fourth separator 213 may be, for example, a heat insulation plate or a component with heat insulation function. The high-voltage electrical components may, for example, include a first circuit board 31 and a second circuit board 32. The first circuit board 31 is disposed at the first mounting position 201, and the second circuit board 32 is disposed at the second mounting position 202. The first circuit board 31 may, for example, be provided with a rectifier filter circuit, and / or the second circuit board 32 may, for example, be provided with a transformer circuit. In some embodiments, in order to further reduce the length of the charging device 100, only the first separator 211 and the fourth separator 213 may be provided, while the second separator 212 may be omitted.

[0064] The low-voltage separator 22 may, for example, be provided with a battery mounting position 206, and the battery 35 is mounted on the battery mounting position 206. Referring again to Figures 6 and 7, the low-voltage electrical components may, for example, include a third circuit board 33, on which a DC-DC conversion circuit is provided. The low-voltage separator 22 also includes a fifth partition 222, which is connected to the third partition 221 and forms a third mounting position 203 and a battery mounting position 206 located on both sides of the fifth partition 222. The third circuit board 33 is mounted on the third mounting position 203. The extending direction of the third partition 221 is perpendicular to the extending direction of the fifth partition 222. The third partition 221 and the fifth partition 222 can be connected by integral molding or splicing assembly. Similarly, the fifth partition 222 is also a heat insulation plate or a component with heat insulation function. Furthermore, the battery mounting position 206 may extend along the length direction of the housing 1, for example, and the battery 35 may be placed along the length direction of the housing 1. With such an arrangement, the area of ​​proximity between the battery 35 and the first circuit board 31 can be reduced, thereby reducing the heat transfer area between the battery 35 and the first circuit board 31, and further reducing the impact of heat generation between the battery 35 and the first circuit board 31.

[0065] The low-voltage electrical components may also include, for example, a fourth circuit board 34, which is electrically connected to the third circuit board 33. The fourth circuit board 34 is provided with a digital display circuit and a charging interface 50. A fourth mounting position 204 is also provided between the low-voltage separator 22 and the second housing 12, and the fourth circuit board 34 is located in the fourth mounting position 204. Furthermore, the fourth circuit board 34 preferably does not have a heat source device. The second housing 12 may also have a lanyard 7, for example. Since the second housing 12 has a charging interface 50 and a lanyard 7, it is a high-frequency contact area for the user. Not having a heat source device can prevent the second housing 12 from overheating and becoming too hot to touch, thus affecting the user experience.

[0066] For example, referring to Figures 8 and 9, the first circuit board 31 is provided with an electrolytic capacitor 311, a fuse module 312, a common-mode inductor 313, and a rectifier module 314; referring to Figure 10, the second circuit board 32 is provided with a main control chip 321, an optocoupler 322, a solid-state capacitor 323, and a transformer 324; referring to Figures 11 and 12, the third circuit board 33 is provided with a charge / discharge management chip 331, a first socket 332 for electrical connection with the battery cell cable, a second socket 333 electrically connected to the fourth circuit board 34 via an FPC (Flexible Printed Circuit), and a charging protocol chip 334; referring to Figures 13 and 14, the fourth circuit board 34 may, for example, be provided with a digital display tube bracket 341, a digital display module 342, and a third socket 343 electrically connected to the third circuit board 33 via an FPC (Flexible Printed Circuit). Of course, this embodiment is not limited to this. A heat spreader 37 may be provided between the first circuit board 31 and the first housing 11, for example, the heat spreader 37 may be a heat conduction component or a heat dissipation component, thereby further improving the heat dissipation effect. Of course, a heat spreader 37 may also be provided between other circuit boards and the housing 1, and this embodiment is not limited thereto.

[0067] In one embodiment of this invention, the multiple partitioned regions may include, for example, a first heat insulation region, a second heat insulation region, a third heat insulation region, and a fourth heat insulation region. The first and second heat insulation regions are separated along the thickness direction of the outer casing 1, and the third and fourth heat insulation regions are also separated along the thickness direction of the outer casing 1. The first and third heat insulation regions are spaced apart along the length direction of the outer casing 1. A battery 35 is disposed in the fourth heat insulation region. The battery 35 includes, for example, two cylindrical rechargeable cells. The two cells are placed parallel to each other along the length direction of the outer casing 1 within the battery mounting position 206 (fourth heat insulation region), and the two cells are arranged along the width direction of the outer casing 1. The length direction, width direction, and thickness direction of the outer casing 1 are perpendicular to each other. In this embodiment, the width of the outer casing 1 is greater than its thickness. Electronic components may include, for example, an electrolytic capacitor 311, a charging protocol chip 334, a charge / discharge management chip 331, a main control chip 321, and a transformer 324. Electrolytic capacitor 311 is disposed in the first heat insulation zone; charging protocol chip 334 and charge / discharge management chip 331 are disposed in the second heat insulation zone; main control chip 321 and transformer 324 are disposed in the third heat insulation zone. Of course, this embodiment is not limited thereto.

[0068] Referring again to Figures 3 and 6, a fifth mounting position 205 is also provided on the low-voltage separator 22. The third mounting position 203 and the fifth mounting position 205 are arranged adjacent to each other on the same side of the fifth partition 222, and the fifth mounting position 205 is located on the side closer to the charging interface 50.

[0069] The charging device 100 also includes a retractable cable module 6, which includes a module body 61 disposed on a fifth mounting position 205. The fifth mounting position 205 is, for example, an installation area surrounded by multiple curved limiting walls protruding from the surface of the low-voltage separator 22. The module body 61 can be fixedly connected to this installation area by means of snap-fit ​​connection, screw locking, adhesive bonding, etc. The retractable cable module 6 also includes a data cable 62 that can be wound and stored in the module body 61 and a data cable connector 63 disposed on the outside of the housing 1. One end of the data cable 62 is wound and stored in the module body 61, and the other end of the data cable 62 is connected to the data cable connector 63 on the outside of the housing 1.

[0070] Preferably, as shown in Figures 1 and 3, the second housing 12 is recessed with a connector slot 121 for accommodating the data cable connector 63 and a display part 122 corresponding to the digital display module 342. The display part 122 is made of transparent or semi-transparent material, so that the text displayed by the digital display module 342 can be displayed externally through the display part 122. The connector slot 121 and the display part 122 are arranged along the thickness direction of the housing 1, while the display part 122 and the charging interface 50 are arranged along the width direction of the housing 1. The compact arrangement helps to reduce the overall product volume. The second housing 12 is provided with a first magnet 123 corresponding to the connector slot 121. The first magnet 123 is located on the inner surface of the second housing 12. The data cable connector 63 is provided with a second magnet that can be attracted to the first magnet 123. When the data cable connector 63 is located in the connector slot 121, the data cable connector 63 is stably housed in the connector slot 121 by the attraction between the second magnet and the first magnet 123.

[0071] Preferably, the second housing 12 has a lanyard connection portion 124 at one end in the width direction of the outer housing 1. The lanyard connection portion 124 protrudes from the surface of the second housing 12 along the length direction of the outer housing 1. The two ends of the lanyard 7 are respectively inserted into the lanyard connection portion 124, so that the lanyard 7 forms a loop-shaped handle space. As shown in Figure 1, the lanyard connection portion 124 and the plug 41 are located on the same side of the outer housing 1, so that when the charging device 100 is inserted into the socket through the plug 41, the lanyard 7 can be located on the side closer to the socket, avoiding the lanyard 7 from blocking the user from taking out the data cable connector 63.

[0072] Preferably, the length of the data cable 62 is between 50cm and 120cm. This length range can meet the user's basic needs for charging range, while avoiding the module body 61 being too large and occupying too much space inside the outer shell 1.

[0073] With the extension cable module 6, users can extend the data cable 62 out of the housing 1 through the data cable connector 63, making it convenient for users to charge over a longer distance. When charging is not needed, the data cable 62 can be rolled up inside the charging device 100, which increases the data cable storage function, so that users do not need to carry an extra data cable and make full use of the internal space of the charging device 100.

[0074] [Second Embodiment]

[0075] Please refer to Figures 15 to 20. The second embodiment of this application provides a charging device 100, which differs from the first embodiment mainly in the plug module. Specifically, the charging device 100 in this embodiment includes a charging body 10 and a plug module 4 electrically connected to the charging body 10. The plug module 4 is used to connect to an external power source, such as a power strip or socket, to achieve power conduction and thus charge the charging body 10 or electronic devices electrically connected to the charging body 10. In this embodiment, the specific product type of the charging device 100 is the same as in the first embodiment, and will not be described again here.

[0076] The plug module 4 includes a plug 41 and a mounting accessory 42. The charging body 10 includes a main housing 101 and a charging module 3 located within the main housing 101. The mounting accessory 42 is located at a corner of the main housing 101 of the charging body 10 and is separately connected to the main housing 101. The mounting accessory 42 and the main housing 101 constitute the main part of the entire outer shell of the charging device 100. Specifically, the mounting accessory 42 is, for example, the first housing 11 in the first embodiment, and the main housing 101 is, for example, a combination of the third housing 13 and the fourth housing portion 14 in the first embodiment. Based on this, the charging body 10 is, for example, a combination of the second housing 12, the third housing 13, the fourth housing portion 14, and the charging module 3 in the first embodiment. The plug 41 is mounted on the mounting accessory 42 and electrically connected to the charging module 3 of the charging body 10, for example, through a charging cable. The mounting accessory 42 is separately connected to the main housing 101 of the charging body 10. That is, the two are formed separately and then assembled together. Therefore, during the assembly process, the mounting accessory 42 can be separated from the main housing 101 of the charging body 10 first, and the pin 41 can be installed to the mounting accessory 42 to form the pin module 4. Then, the mounting accessory 42 can be connected to the housing of the charging body 10 to assemble the pin module 4 and the charging body 10 together. The installation of the pin 41 will not be affected by the charging body 10, which can reduce the assembly difficulty.

[0077] By placing the mounting accessory 42 at the corner of the main housing 101, when the charging device 100 is dropped and the mounting accessory 42 is impacted, the mounting accessory 42, as an independent component, has relatively lower overall strength compared to a corner of the integrally molded housing. Therefore, it is more prone to deformation, which can convert part of the impact into the energy required for the deformation of the mounting accessory 42. This helps reduce the risk of damage to the mounting accessory 42 and improves the drop resistance of the charging device 100. Moreover, when the mounting accessory 42 is damaged due to impact or has quality problems (such as injection molding defects) during the production process, the mounting accessory 42 can be replaced separately, and the main housing 101 of the charging body 10 does not need to be replaced, that is, the entire housing of the charging device 100 does not need to be replaced. This helps to improve the fault tolerance rate in the production process and reduce production and after-sales costs. At the same time, the mounting accessory 42 is separately connected to the main housing 101, which can prevent the impact force from spreading from the mounting accessory 42 to the main housing 101, reducing the risk of damage to the main housing 101.

[0078] The specific number of pins 41 is not limited, for example, two or three. In this application, the number of pins 41 is two, and the two pins 41 are arranged in parallel with a gap between them.

[0079] The specific connection method between the mounting accessory 42 and the charging body 10 is not limited, such as by screw fastening, snap-fit ​​connection, glue connection, etc.

[0080] The main housing 101 has a pin mounting position 102 at its corner. The shape of the pin mounting position 102 is adapted to the shape of the mounting accessory 42. The mounting accessory 42 is installed to the pin mounting position 102 to enhance the compactness between the main housing 101 and the mounting accessory 42 and reduce the obtrusiveness of the mounting accessory 42.

[0081] Understandably, the pin mounting position 102 can be a mounting groove formed by a recess on the outer side of the main housing 101, the mounting groove being recessed from the outer surface of the housing to the inner surface and spaced a certain distance from the inner surface; or, the pin mounting position 102 can be a notch penetrating the main housing 101, the notch connecting the interior and exterior spaces of the main housing 101.

[0082] In one embodiment of this invention, the pin mounting position 102 is a notch provided in the main housing 101, penetrating the main housing 101 to increase the depth of the pin mounting position 102 and facilitate the storage of the mounting accessory 42. Preferably, the outline shape of the notch matches the outline shape of the mounting accessory 42. After the mounting accessory 42 is installed into the notch, the outer surface of the mounting accessory 42 is flush with the outer surface of the main housing 101, that is, the mounting accessory 42 does not protrude from the main housing 101, further reducing the abruptness of the mounting accessory 42.

[0083] The charging module 3 includes a battery 35, which stores electrical energy for charging electronic devices. Specifically, the charging module 3 also includes a circuit board and a charging cable. The circuit board is electrically connected to the battery 35 and the charging cable, respectively. Both the circuit board and the battery are located inside the main housing 101. One end of the charging cable extends to the outside of the main housing 101 and is provided with a charging connector for connecting to an electronic device, thereby using the battery 35 to charge the electronic device. The plug 41 is electrically connected to the circuit board, thereby charging the battery after an external power source is connected.

[0084] Preferably, the charging cable is the data cable of the retractable cable module 6, which has a retractable storage function. When not in use, the charging cable can be wound and stored inside the main housing 101, and when needed, the charging cable can be pulled out for user convenience. The structure of the retractable cable module 6 is the same as in the first embodiment, and will not be described again here.

[0085] In one embodiment of this invention, the main housing 101 includes a first side shell 1013 and a second side shell 1014 covering the first side shell 1013. The first side shell 1013 and the second side shell 1014 enclose a storage space, within which the battery and circuit board are stored. By dividing the main housing 101 into the first side shell 1013 and the second side shell 1014, during the assembly of the charging body 10, the first side shell 1013 and the second side shell 1014 can be separated first, then the charging module 3 can be installed on the second side shell 1014, and then the first side shell 1013 can be replaced, fixing the first side shell 1013 and the second side shell 1014 relatively in place. This completes the assembly of the charging body 10, reducing the difficulty of installing the charging module 3. In this embodiment, the first side shell 1013 is, for example, the third housing 13 in the first embodiment, and the second side shell 1014 is, for example, the fourth housing 14 in the first embodiment.

[0086] The connection method between the first side shell 1013 and the second side shell 1014 is not limited, and can be, for example, by screw fastening or snap-fit ​​connection. In this embodiment, the first side shell 1013 and the second side shell 1014 are snap-fit ​​connected, so that the main shell 101 can be assembled without the need for tools, which facilitates assembly.

[0087] In one embodiment of this invention, the plug 41 is rotatably mounted on the mounting accessory 42, and the mounting accessory 42 is provided with a storage groove 425 for accommodating the plug 41. When the plug 41 is not in use, it can be rotated to store it in the storage groove 425, so that the plug 41 is in a stored state, which can protect the plug 41 and reduce the overall size of the charging device 100 when not in use, making it convenient to carry and store. When it is needed, the plug 41 is rotated out from the storage groove 425, so that the plug 41 protrudes out of the mounting accessory 42 to form an extended state for plugging into a socket or power strip.

[0088] In order to improve the overall strength of the mounting accessory 42, so that it can play a certain buffering role when it is impacted, thereby reducing the impact on the pin 41, reducing the risk that the pin 41 will not be able to smoothly rotate out of the storage slot 425 due to impact, and improving the drop resistance of the charging device 100.

[0089] The mounting accessory 42 has a reinforcing section 426 around its periphery, and a slot 427 on the reinforcing section 426. A flange 103 is provided on the inner wall of the pin mounting position 102. The flange 103 inserts into the slot 427, creating a snap-fit ​​connection between the mounting accessory 42 and the main housing 101. The reinforcing section 426 enhances the strength of the periphery of the mounting accessory 42, thereby improving the connection strength between the mounting accessory 42 and the main housing 101, and also facilitates the installation of the slot 427.

[0090] Specifically, the reinforcing part 426 is provided with a snap hole that communicates with the slot 427, and the main housing 101 is provided with a snap part around the pin mounting position 102. When the mounting accessory 42 is installed to the notch, the snap part is inserted into the snap hole, so that the mounting accessory 42 and the main housing 101 form a snap connection, further enhancing the connection strength between the mounting accessory 42 and the main housing 101.

[0091] In one embodiment of this example, the main housing 101 includes two housing ends 1011 and a housing side portion 1012 connected between the two housing ends 1011. A pin mounting position 102 extends from one of the housing ends 1011 to the housing side portion 1012. The mounting accessory 42 is connected to the housing end 1011 and the housing side portion 1012 at the pin mounting position 102, respectively. That is, the pin mounting position 102 is partially located at the housing end 1011 of the main housing 101 and partially located at the housing side portion 1012 of the main housing 101. When the mounting accessory 42 is located at the pin mounting position 102, it is partially connected to the housing end 1011 and partially connected to the housing side portion 1012.

[0092] The specific number of housing side portions 1012 is not limited; it can be one, three, or more. In this embodiment, there are four housing side portions 1012, which are arranged opposite each other in pairs to form a square cross-section. The mounting accessory 42 can be connected to one of the housing side portions 1012, or it can be connected to two or three housing side portions 1012.

[0093] The mounting accessory 42 includes a first wall portion 421 and a second wall portion 422 connected to one end of the first wall portion 421. The first wall portion 421 and the second wall portion 422 are arranged at an angle, that is, the mounting accessory 42 extends from the housing side portion 1012 of the main housing 101 to the housing end portion 1011. The first wall portion 421 is connected to the housing side portion 1012 of the main housing 101, and the second wall portion 422 is connected to the housing end portion 1011 of the main housing 101. The pin 41 is installed on the first wall portion 421. When the mounting accessory 42 is impacted, the impact force will be diffused to the first wall portion 421 and the second wall portion 422 respectively, so that the impact force is diffused in different directions, which plays a role in dispersing the impact force and reducing the risk of damage to the mounting accessory 42 due to excessive local impact force.

[0094] Understandably, the first wall portion 421 and the second wall portion 422 being set at an angle means that the first wall portion 421 and the second wall portion 422 extend in different directions, and a certain angle is formed between the two different directions. The first wall portion 421 and the second wall portion 422 can be straight or have a certain curvature, as long as their extension directions are different.

[0095] The specific angle between the first wall portion 421 and the second wall portion 422 is not limited. In this embodiment, the first wall portion 421 and the second wall portion 422 are perpendicular or nearly perpendicular to each other, that is, the angle between the first wall portion 421 and the second wall portion 422 is 90° or nearly 90°. The overall shape of the mounting accessory 42 is basically L-shaped. The shape of the pin mounting position 102 on the main housing 101 is adapted to the shape of the mounting accessory 42, that is, the shape of the pin mounting position 102 is basically L-shaped.

[0096] Preferably, the first wall portion 421 and the second wall portion 422 are integrally formed to enhance the connection strength between the first wall portion 421 and the second wall portion 422, so as to ensure the overall strength of the mounting accessory 42.

[0097] In one embodiment of this invention, a storage groove 425 is disposed on the first wall portion 421. One end of the storage groove 425 extends to the connection between the first wall portion 421 and the second wall portion 422. When the pin 41 is stored in the storage groove 425, one end of the pin 41 protrudes outside the connection between the first wall portion 421 and the second wall portion 422. This allows the user to press their finger against the end of the pin 41 protruding from the mounting accessory 42 when the pin 41 needs to be used, making it convenient for the user to unscrew the pin from the storage groove 425. Specifically, the connection between the first wall portion 421 and the second wall portion 422 has an arc-shaped transition, thereby forming an arc surface 423 on the outer surface of the connection. One end of the storage groove 425 extends to the arc surface 423. When the pin 41 is stored in the storage groove 425, one end of the pin 41 protrudes outside the arc surface 423.

[0098] In one embodiment of this invention, the mounting accessory further includes a third wall portion, which is connected to the first wall portion and the second wall portion respectively. The housing includes a plurality of sides, and the first wall portion and the third wall portion are connected to adjacent sides respectively.

[0099] Understandably, the number of third wall portions can be one or two. When there is one third wall portion, it is located on one side of the first and second wall portions. When there are two third wall portions, they are located on opposite sides of the first and second wall portions, respectively.

[0100] In one embodiment of this invention, a safety protection structure 424 is provided on the outer side of the mounting accessory 42. The safety protection structure 424 is located on the outer side of the first wall portion 421. When the plug 41 is in the extended state, i.e., rotated out of the storage slot 425, the safety protection structure 424 and the plug 41 protrude from the surface of the first wall portion 421 in the same direction. That is, the safety protection structure 424 and the plug 41 are located on the same side of the first wall portion 421 and extend in the same direction. The safety protection structure 424 can come into contact with external objects such as power strips or sockets when the plug 41 is inserted, thus maintaining a certain distance between the first wall portion 421 and the external object, increasing the creepage distance from the first wall portion 421 to the plug 41, thereby meeting safety regulations and reducing safety hazards.

[0101] The number of safety protection structures 424 is not limited, for example, one or more. In this embodiment, there are two safety protection structures 424, which are spaced apart and located on the outside of the two storage slots 425 respectively. Two pins 41 are located between the two safety protection structures 424, and the pins 41 are spaced a certain distance from the corresponding safety protection structure 424.

[0102] Specifically, the safety protection structure 424 is a protrusion provided on the surface of the first wall portion 421, and the protrusion extends along the length direction of the main housing 101.

[0103] The plug 41 is a metal connector. A partial insulating element 43 is provided on the outer side of the plug 41. The insulating element 43 provides insulation. The end of the plug 41 furthest from the mounting accessory 42, i.e., the end used to insert into the socket or power strip, extends beyond the insulating element 43. The length of the insulating element 43 is less than the length of the plug 41, only covering a portion of the plug 41. This reduces the risk of electric shock to the user from contacting the plug 41 during product insertion and removal, without affecting the connection to an external power source, thus mitigating safety hazards.

[0104] Understandably, the specific form of the insulating member 43 is not limited. It can be an insulating layer formed on the surface of the pin 41 by insulating material, or it can be an insulating sleeve fitted onto the outside of the pin 41. In this embodiment, the insulating member 43 is an insulating sleeve. The outer side of the pin 41 is recessed to form a socket portion 411. The socket portion 411 surrounds the outer periphery of the pin 41. The insulating member 43 is fitted onto the outside of the pin 41 and housed within the socket portion 411. The outer surface of the insulating member 43 is flush with the outer surface of the pin 41. Therefore, the overall thickness of the pin 41 will not increase due to the provision of the insulating member 43.

[0105] The plug 41 includes a connecting end 412 and a plug-in end 413 located on one side of the connecting end 412. The connecting end 412 is connected to the mounting accessory 42, and the plug-in end 413 is used to insert external devices such as sockets or power strips. An insulating member 43 and a socket part 411 are provided on the connecting end 412, and the insulating member 43 is sleeved on the outer periphery of the socket part 411.

[0106] In one embodiment of this example, the pin module 4 further includes a rotating shaft 414. The pin 41 is fixed relative to the rotating shaft 414. The rotating shaft 414 is rotatably connected to the first wall portion 421. The pin 41 is indirectly rotatably mounted to the first wall portion 421 through the rotating shaft 414, so that when the rotating shaft 414 rotates relative to the first wall portion 421, it drives the pin 41 to rotate together relative to the first wall portion 421.

[0107] The specific number of rotating shafts 414 is not limited; it can be one rotating shaft 414 connected to one pin 41, or one rotating shaft 414 connected to two pins 41. In this embodiment, the two pins 41 are respectively fixed to both ends of the rotating shaft 414, so that when the rotating shaft 414 rotates, it drives the two pins 41 to rotate synchronously.

[0108] A mounting base 44 is provided on the inner side of the first wall portion 421, and a rotating shaft 414 is rotatably mounted to the mounting base 44. The mounting base 44 includes a base body 441 and a cover body 442 covering the base body 441. The base body 441 is located on the inner side of the first wall portion 421, and the rotating shaft 414 is sandwiched between the base body 441 and the cover body 442. Dividing the mounting base 44 into two parts, the base body 441 and the cover body 442, allows the rotating shaft 414 to be installed by first separating the base body 441 and the cover body 442, then installing the rotating shaft 414 on the base body 441, and finally covering it with the cover body 442, thus clamping the rotating shaft 414 between the base body 441 and the cover body 442, placing the rotating shaft 414 inside the mounting base 44, reducing the difficulty of installing the rotating shaft 414. Specifically, the base body 441 and the cover body 442 are fixedly connected by fasteners such as bolts to ensure the stability of the connection between the base body 441 and the cover body 442.

[0109] The base 441 has a first recess on the side near the cover 442, and the cover 442 has a corresponding second recess. When the cover 442 is placed on the base 441, the first recess and the second recess cooperate to form a shaft hole. The rotating shaft 414 is rotatably installed in the shaft hole. During assembly, it is only necessary to place the rotating shaft 414 in the first recess of the base 441 and then cover it with the cover 442 to achieve a rotational engagement between the rotating shaft 414 and the mounting base 44.

[0110] The base 441 is provided with a positioning post 443 on the side near the cover 442. The cover 442 is provided with a positioning hole 444 for the positioning post 443 to be inserted. The cooperation between the positioning post 443 and the positioning hole 444 can form a positioning effect when the cover 442 is installed on the base 441, so as to quickly find the installation position of the cover 442.

[0111] In one embodiment of this example, a positioning post 443 can be provided on the cover 442, and a corresponding positioning hole 444 can be provided on the base 441, which can achieve the same positioning effect.

[0112] Preferably, there are multiple positioning pins 443 and positioning holes 444, each corresponding to the other, and each positioning pin 443 can be inserted into a corresponding positioning hole 444 to enhance the positioning effect.

[0113] The inner side of the first wall portion 421 is provided with a recessed portion 4211, and the seat body 441 of the mounting base 44 is located in the recessed portion 4211 to reduce the overall thickness of the first wall portion 421 and the seat body 441, thereby reducing the installation space inside the main housing 101 occupied by the mounting base 44.

[0114] The second wall portion 422 is located on one axial side of the battery 35 and is spaced apart from the battery 35. The inner side of the second wall portion 422 is provided with a recess 4221 corresponding to the battery 35 to avoid the battery 35. The mounting accessory 42 can play a certain buffering role, so that the second wall portion 422 is located on the outer axial side of the battery 35, which can reduce the risk of the battery 35 being impacted, thereby protecting the battery 35.

[0115] In one embodiment of this invention, the plug module 4 further includes a conductive member 45 sandwiched between the base 441 and the cover 442. One end of the conductive member 45 is located between the base 441 and the cover 442 and is electrically connected to the plug 41. The other end of the conductive member 45 is located outside the mounting base 44 and is electrically connected to the charging body 10, i.e., the charging module 3, thereby making the plug 41 electrically connected to the charging module 3.

[0116] In one embodiment of this invention, the conductive element 45 is a metal spring sheet, which makes the conductive element 45 not only conductive but also elastic.

[0117] The conductive component 45 is provided with a clearance hole 451, which corresponds to the positioning post 443. When the conductive component 45 is sandwiched between the base 441 and the cover 442, the positioning post 443 passes through the clearance hole 451 and is inserted into the positioning hole 444, thereby creating a positioning effect on the conductive component 45 and enhancing the stability of the conductive component 45.

[0118] The conductive element 45 includes a clamping part 452 and an elastic connecting part 453. The clamping part 452 is clamped between the base body 441 and the cover body 442. The elastic connecting part 453 is connected to one end of the clamping part 452 and is electrically connected to the plug 41. The end of the conductive element 45 that is electrically connected to the charging body 10 is connected to the end of the clamping part 452 away from the elastic connecting part 453.

[0119] The elastic connection portion 453 is inclined relative to the clamping portion 452, that is, an angle is formed between the elastic connection portion 453 and the clamping portion 452, and the elastic connection portion 453 extends inclinedly from the clamping portion 452 toward the first wall portion 421. The angle is greater than 90° and less than 180°, so that the elastic connection portion 453 has a certain elasticity. During the rotation of the plug 41 relative to the first wall portion 421, the plug 41 will squeeze the elastic connection portion 453, causing the elastic connection portion 453 to undergo elastic deformation, thereby forming an elastic force. Under the action of its own elastic force, the elastic connection portion 453 presses tightly onto the plug 41, so that the plug 41 always maintains contact with the conductive component 45 during the rotation, forming an electrical connection effect.

[0120] Specifically, when the pin 41 is stored in the storage slot 425, one end of the pin 41 abuts against the end of the elastic connecting portion 453 away from the clamping portion 452. When the pin 41 is rotated out of the storage slot 425, the end of the pin 41 that abuts against the elastic connecting portion 453 moves towards the clamping portion 452 along the extending direction of the elastic connecting portion 453 and squeezes the elastic connecting portion 453.

[0121] The elastic connecting part 453 has a connecting part groove 4531 on the side facing the pin 41. One end of the pin 41 (i.e. the connecting end 412) has a connecting end protrusion 4121 that mates with the connecting part groove 4531. The connecting end protrusion 4121 can be movably inserted into the connecting part groove 4531. When the pin 41 rotates relative to the first wall part 421, the connecting end protrusion 4121 slides in the connecting part groove 4531, which plays a certain guiding role and prevents the pin 41 from separating from the elastic connecting part 453.

[0122] In one embodiment of this invention, the charging body 10 is provided with a lanyard 7, and the inner side of the lanyard 7 forms a carrying space, so that the user can carry or hang the charging device 100 on his hand through the lanyard 7 without having to hold it in his hand.

[0123] [Third Embodiment]

[0124] Please refer to Figures 21 to 27. The charging device 100 provided in the third embodiment of this application differs from that in the first embodiment mainly in the internal partition structure and the charging module. Specifically, the charging device 100 in this embodiment includes a main housing 101, a charging module 3, and a battery 35. The charging module 3 and the battery 35 are both located inside the main housing 101, and the charging module 3 is electrically connected to the battery 35.

[0125] The main housing 101 has a first partition 23 and a second partition 24 inside. The first partition 23, the second partition 24, and the main housing 101 cooperate to form a heat insulation cavity 251. The charging module 3 is located inside the heat insulation cavity 251, and the battery 35 is located outside the heat insulation cavity 251. During operation, the charging module 3 generates a large amount of heat. The first partition 23 and the second partition 24 can, to a certain extent, block the heat transfer from the heat insulation cavity 251 to the outside, reduce the heat transfer from the charging module 3 to the battery 35, reduce the impact of the heat generated by the charging module 3 on the battery 35, and help ensure the normal operation of the battery 35 and extend its service life. At the same time, the first partition 23 and the second partition 24 can also play a role in electrical isolation, preventing creepage between the charging module 3 and the battery 35 and reducing safety hazards.

[0126] In one embodiment of this example, both the first partition 23 and the second partition 24 are plate-shaped, that is, both the first partition 23 and the second partition 24 are partition plates.

[0127] A storage space 25 is formed between one side of the second separator 24 and the main housing 101. The first separator 23 is located within the storage space 25 and divides the storage space 25 into a heat insulation cavity 251 and a battery cavity 252. The charging module 3 is located in the heat insulation cavity 251, and the battery 35 is located in the battery cavity 252. The first separator 23 divides the storage space 25 located on one side of the second separator 24 into two cavities, namely the heat insulation cavity 251 and the battery cavity 252. The charging module 3 and the battery 35 are respectively stored in the heat insulation cavity 251 and the battery cavity 252. The first separator 23 is located between the charging module 3 and the battery 35. The first separator 23 can block heat transfer from the heat insulation cavity 251 to the battery cavity 252 to a certain extent, reduce the impact of the charging module 3 on the battery 35, and at the same time play a role in electrical isolation.

[0128] It should be noted that the first partition 23 and the second partition 24, to a certain extent, block the heat from the insulation cavity 251 to the outside. This means that they hinder the heat transfer and reduce the amount and speed of heat transfer to the outside. They do not completely prevent the heat from spreading outward. Some of the heat inside the insulation cavity 251 can still spread to the outside of the insulation cavity 251 through the first partition 23 and the second partition 24.

[0129] In one embodiment of this example, the heat insulation cavity 251 can be formed in other ways. For example, a first partition 23 can be provided inside the main housing 101. By adjusting the position or shape of the first partition 23, the heat insulation cavity 251 can be formed by the cooperation of the first partition 23 and the main housing 101. The charging module 3 and the battery 35 are located on opposite sides of the first partition 23, which can also achieve the effect of separating the charging module 3 and the battery 35.

[0130] In one embodiment of this invention, the opposite ends of the first separator 23 are connected to the second separator 24 and the main housing 101, respectively. One side of the first separator 23 cooperates with the second separator 24 and the main housing 101 to form a heat insulation cavity 251, and the other opposite side of the first separator 23 cooperates with the second separator 24 and the main housing 101 to form a battery cavity 252. That is, the heat insulation cavity 251 and the battery cavity 252 are located on opposite sides of the first separator 23. When the first separator 23 and the second separator 24 are assembled together, the cross-sectional shape is approximately T-shaped, which enables the first separator 23 and the second separator 24 to provide a more stable support effect for the devices inside the main housing 101 and improve the impact resistance of the charging device 100.

[0131] In one embodiment of this example, as shown in Figures 23 and 24, the opposite sides of the first separator 23 refer to the two sides of the first separator 23 that are opposite to each other in the width direction of the outer shell, and the opposite ends of the first separator 23 refer to the two ends that are opposite to each other in the thickness direction of the outer shell.

[0132] In one embodiment of this example, the first separator 23 and the second separator 24 may also be arranged in parallel with a gap, with a heat insulation cavity 251 formed between the first separator 23 and the second separator 24, and a battery cavity 252 formed between the first separator 23 and the main housing 101.

[0133] Preferably, the main housing 101 has a length direction, a width direction, and a thickness direction consistent with the outer casing. The dimension of the main housing 101 in the length direction is larger than its dimensions in the width direction and the thickness direction, respectively, and the dimension of the main housing 101 in the width direction is larger than its dimension in the thickness direction. The first partition 23 and the second partition 24 both extend along the length direction of the main housing 101, thereby causing the heat insulation cavity 251 and the battery cavity 252 to both extend along the length direction of the main housing 101, so that the heat insulation cavity 251 and the battery cavity 252 have a large length to accommodate the charging module 3 and the battery 35.

[0134] In one embodiment of this example, the first partition 23 and the second partition 24 are vertically connected, that is, the connection between the first partition 23 and the second partition 24 forms a vertical effect, so as to form a more stable support effect.

[0135] The first separator 23 has extensions 231 at both ends of the battery 35 along its length. The two extensions 231 are spaced apart from each other and extend from the first separator 23 in a direction away from the heat insulation cavity 251, so that the first separator 23 and the two extensions 231 cooperate to form a U-shaped structure. The battery 35 is located between the two extensions 231, thereby enhancing the heat insulation effect of the first separator 23 and improving the protection effect of the battery 35. Specifically, the two extensions 231 are perpendicularly connected to the first separator 23.

[0136] The second separator 24 includes a straight portion 241 and an arc-shaped portion 242. The straight portion 241 is perpendicularly connected to the first separator 23, and the arc-shaped portion 242 is connected to the side of the straight portion 241 near the battery cavity 252 and fits against the outer surface of the battery 35, thereby creating a certain limiting effect on the battery 35 and reducing the risk of the battery 35 shaking in the battery cavity 252.

[0137] Specifically, the arc-shaped portion 242 is located on one side of the straight portion 241 in the width direction, and the arc-shaped portion 242 and the straight portion 241 are integrally formed to ensure the overall strength of the second separator 24.

[0138] The side of the second separator 24 away from the storage space 25 forms a heat dissipation cavity 26 with the main housing 101. That is, the second separator 24 divides the internal space of the main housing 101 into a heat dissipation cavity 26 and a storage space 25. The first separator 23 then divides the storage space 25 into a heat insulation cavity 251 and a battery cavity 252. When the charging module 3 is working, the heat generated first diffuses within the heat insulation cavity 251. A portion of the heat in the heat insulation cavity 251 diffuses outwards through the corresponding portion of the main housing 101. A portion of the heat in the heat insulation cavity 251 diffuses into the battery cavity 252 through the first separator 23. The heat in the battery cavity 252 then diffuses outwards through the corresponding portion of the main housing 101. A portion of the heat in the heat insulation cavity 251 diffuses into the heat dissipation cavity 26 through the second separator 24, and a portion of the heat in the battery cavity 252 also diffuses into the heat dissipation cavity 26 through the second separator 24. The heat in the heat dissipation cavity 26 then diffuses outwards through the corresponding portion of the main housing 101. This design helps to achieve a relatively uniform heat distribution inside the main housing 101, thereby avoiding the problem of localized overheating.

[0139] Understandably, when the heat insulation cavity 251, the battery cavity 252, and the heat dissipation cavity 26 are connected by a connecting structure such as a through hole or a gap, heat can diffuse from the heat insulation cavity 251 into the battery cavity 252 and the heat dissipation cavity 26 with the air flow, and is not limited to diffusion outward by relying on the first separator 23 and the second separator 24.

[0140] In one embodiment of this invention, a telescopic cable module 6 is provided inside the heat dissipation cavity 26. The telescopic cable module 6 is installed on the second partition 24 and electrically connected to the charging module 3. The telescopic cable module 6 has the function of retracting and storing the data cable 62. When not in use, it can be wound up and stored inside the main housing 101. When needed, it can be pulled out from the main housing 101 to a suitable length for user convenience. Moreover, when the data cable 62 is pulled out to the outside of the main housing 101, the data cable 62 can also assist in the heat dissipation of the heat dissipation cavity 26.

[0141] The telescopic cable module 6 is located on one side of the second partition 24, while the charging module 3 and battery 35 are located on the opposite side of the second partition 24. That is, the telescopic cable module 6, the charging module 3, and the battery 35 are arranged along the thickness direction of the second partition 24, and the charging module 3 and battery 35 are located on the same side of the second partition 24. The charging module 3 and battery 35 are respectively located on opposite sides of the first partition 23, meaning they are arranged along the thickness direction of the first partition 23. This arrangement of the telescopic cable module 6, the charging module 3, and the battery 35 in two different directions makes the internal arrangement of components in the main housing 101 more compact, preventing the charging device 100 from being too large in one direction and facilitating product miniaturization. Specifically, the telescopic cable module 6, the charging module 3, and the battery 35 are arranged along the thickness direction of the main housing 101, and the charging module 3 and battery 35 are arranged along the width direction of the main housing 101.

[0142] In one embodiment of this invention, the main housing 101 includes a second side housing 1014 and a first side housing 1013 covering one side of the second side housing 1014. Both the second side housing 1014 and the first side housing 1013 have cavities formed inside. A second partition 24 is connected to the second side housing 1014 and / or the first side housing 1013, forming a storage space 25 between the second partition 24 and the second side housing 1014. The first partition 23, the charging module 3, and the battery 35 are all located between the second partition 24 and the second side housing 1014. A heat dissipation cavity 26 is formed between the second partition 24 and the first side housing 1013. The telescopic cable module 6 is located between the second partition 24 and the first side housing 1013. The main housing 101 is configured into two parts: a second side housing 1014 and a first side housing 1013. During the assembly process, the second side housing 1014 and the first side housing 1013 can be separated first, which facilitates the installation of the charging module 3, the battery 35, and the telescopic cable module 6.

[0143] The connection method between the second side shell 1014 and the first side shell 1013 is not limited, such as snap-fit ​​connection, connection by fasteners, etc.

[0144] In one embodiment of this example, the charging module 3 includes a main control circuit assembly 30, which includes a first substrate 301 and a plurality of electrical components 304 disposed on the first substrate 301, such as capacitors, inductors, transformers, control chips, optocouplers, etc. The first substrate 301 is mounted to the side of the second partition 24 near the storage space 25, and at least some of the electrical components 304 are located on the side of the first substrate 301 away from the second partition 24.

[0145] A mounting gap 253 is formed between the first substrate 301 and the second partition 24. Some electrical components 304 are located within the mounting gap 253, that is, between the first substrate 301 and the second partition 24. Forming the mounting gap 253 between the first substrate 301 and the second partition 24 can reduce the contact area between the first substrate 301 and the second partition 24, thereby improving the heat dissipation capacity of the main control circuit assembly 30. At the same time, the mounting gap 253 is used to install the electrical components 304, making full use of the space of the heat insulation cavity 251, so as to reduce the overall size of the product.

[0146] Specifically, among the multiple electrical components 304 on the first substrate 301, the larger electrical components 304, such as capacitors, inductors, and transformers, are located on the side of the first substrate 301 away from the second separator 24, while the smaller electrical components 304, such as control chips and optocouplers, are located on the side of the first substrate 301 closer to the second separator 24, that is, within the mounting gap 253.

[0147] There is a gap between the electrical component 304 on the first substrate 301 and the main housing 101, that is, the electrical component 304 does not directly contact the main housing 101, and the heat of the electrical component 304 is not directly transferred to the main housing 101, so as to avoid the main housing 101 from contacting the electrical component 304 and causing the contact area to overheat, thus preventing burns.

[0148] In one embodiment of this invention, the charging device 100 further includes a plug module 4 mounted on the main housing 101. The plug 41 of the plug module 4 is electrically connected to the charging module 3. The plug 41 is used to connect to a socket or power strip to an external power source, thereby charging the battery 35. Users do not need to carry an additional charger, making it convenient for them to use. The structure of the plug module 4 is the same as in the first or second embodiment, and will not be described again here.

[0149] The specific method by which the plug 41 is electrically connected to the charging module 3 is not limited. For example, it can be directly connected via a wire or indirectly connected via a circuit board. In this embodiment, the charging module 3 further includes a second substrate 302, which is electrically connected to both the plug 41 and the main control circuit assembly 30, thereby achieving the electrical connection between the plug 41 and the charging module 3.

[0150] The second substrate 302 is inserted into the first substrate 301 of the main control circuit assembly 30 near the pin 41, and the second substrate 302 extends away from the second separator 24, so that the first substrate 301 and the second substrate 302 form a mutually perpendicular effect, so as to reduce the overall volume of the charging module 3.

[0151] Specifically, one end of the second substrate 302 is provided with a first insertion part 3021, and the first substrate 301 is provided with a first insertion hole 3011. The second substrate 302 is inserted into the first insertion hole 3011 through the first insertion part 3021 to form an insertion fit with the first substrate 301, thereby reducing the assembly difficulty.

[0152] The charging module 3 also includes a third substrate 303, which is electrically connected to the retractable cable module 6 and the charging module 3, thereby forming an electrical connection between the retractable cable module 6 and the charging module 3.

[0153] The second substrate 302 and the third substrate 303 are respectively disposed at both ends of the first substrate 301, and are respectively inserted into and perpendicularly connected to the first substrate 301. Specifically, the end of the first substrate 301 away from the second substrate 302 is provided with a second insertion portion 3012, and the third substrate 303 is provided with a second insertion hole 3031. The second insertion portion 3012 is inserted into the second insertion hole 3031, so that the third substrate 303 is perpendicular to the first substrate 301. The second substrate 302 and the third substrate 303 are perpendicular to both ends of the first substrate 301, which can improve the compactness of the overall structure and help reduce the overall volume.
