[0001] This invention relates to the field of charging equipment technology, and in particular to a charging device. Background Technology

[0002] With the development of technology, smart devices are becoming increasingly popular, such as laptops and robot vacuums. Laptops offer excellent portability and versatility, meeting users' needs for flexible work and entertainment, while robot vacuums reduce the burden of cleaning by automatically cleaning floors. However, these smart devices all suffer from high power consumption, requiring frequent charging, and the charging process is not always convenient. For example, charging a laptop requires the user to first plug the power adapter into a power outlet, then locate the charging port on the laptop, and visually align the power adapter plug with the charging port to insert it accurately. It's clear that charging this device (laptop) is not only cumbersome but also doesn't support blind operation. Summary of the Invention

[0003] The main objective of this invention is to provide a charging device that improves the ease of operation for powering or charging powered devices.

[0004] To achieve the above objectives, the present invention proposes a charging device for use between a power receiving device and a supporting surface, wherein the power receiving device includes a main control circuit board, and the charging device includes:

[0005] A power supply structure includes at least one power supply electrode group, the power supply electrode group including at least two power supply electrodes, the power supply electrodes being electrically connected to an external power source, and the power supply electrode group being exposed on a support surface; and

[0006] The power receiving structure includes at least two power receiving electrodes, which are exposed on the power receiving device and used to be electrically connected to the main control circuit board. The power receiving electrodes can be electrically connected to the power supply electrodes.

[0007] Optionally, the power supply structure further includes a power supply base for connection to the support surface, wherein the power supply electrodes are exposed on the power supply base.

[0009] Optionally, the power supply structure is configured as a power supply base, the power supply base includes a power supply base body, the power supply base body is configured as the power supply base, and the power supply base body is used to place or embed on the support surface.

[0010] Optionally, the power receiving structure further includes a power receiving substrate for mounting or configuring with the power receiving device as part of the power receiving device, wherein the power receiving electrodes are exposed on the power receiving substrate.

[0011] Optionally, the power receiving structure is configured as a power receiving sheet, the power receiving sheet includes a power receiving base film, the power receiving base film is configured as the power receiving substrate, the power receiving base film has a third mounting surface and a fourth mounting surface opposite to each other, the third mounting surface is used to mount on the power receiving device, and the power receiving electrode is located on the fourth mounting surface.

[0012] Optionally, the power receiving structure is configured as a power receiving base, the power receiving base includes a power receiving base body, the power receiving base body is configured as the power receiving substrate, the power receiving base body is provided with a receiving slot, the receiving slot is used for installing the power receiving device.

[0013] Optionally, the power receiving substrate is configured as the bottom cover of the power receiving device, and the power receiving electrode is disposed on the bottom surface of the bottom cover.

[0014] Optionally, the charging device further includes a table, the tabletop of which is configured as the support surface.

[0015] Optionally, the power supply structure further includes a power adapter, at least one of the power adapters being electrically connected to at least one of the power supply electrode groups, the power adapter being used to be electrically connected to the external power supply.

[0016] Optionally, the power supply electrode is embedded in the support surface.

[0019] Optionally, the receiving electrode is configured as at least one of a conductive foil, a conductive sheet, a conductive film, a flexible circuit board, a metallized plastic body, and a spring pin.

[0020] In this invention, two power supply electrodes located on the support surface serve as the positive terminal and the ground terminal (negative terminal), respectively, and are electrically connected to the two receiving electrodes to form a circuit loop. Thus, when charging is required, the device simply needs to be placed on the support surface so that the power supply electrodes contact the receiving electrodes. At this time, the external power supply's electrical energy passes through the power supply electrodes and the receiving electrodes sequentially to power the main control circuit board and support the normal operation of the device. For example, a laptop's operating power can be directly provided by an external power source, not necessarily by the laptop's internal rechargeable battery. Alternatively, the main control circuit board can charge the rechargeable battery, which then provides the power required for the laptop's operation. Compared to existing technologies, this power supply / charging process is not only simpler to operate but also supports blind operation, thereby improving the convenience of charging the device. For example, for a laptop, the user no longer needs to search for the charging port and align and insert the charging plug each time, thus improving the user's charging experience.

[0021] In addition, the technical solution of this invention can avoid the problem of flying wires on the desktop, making the desktop tidier, and can achieve the wireless charging experience with the efficiency of wired charging. Moreover, compared with wireless charging technology, it can also enable the receiving device to have a larger range of movement on the desktop. Attached Figure Description

[0046] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0048] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0049] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0050] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0051] With the development of technology, smart devices are becoming increasingly popular, such as laptops and robot vacuums. Laptops offer excellent portability and versatility, meeting users' needs for flexible work and entertainment, while robot vacuums reduce the burden of cleaning by automatically cleaning floors. However, these smart devices all suffer from high power consumption, requiring frequent charging, and the charging process is not always convenient. For example, charging a laptop requires the user to first plug the power adapter into a power outlet, then locate the charging port on the laptop, and visually align the power adapter plug with the charging port to insert it accurately. It's clear that charging this device (laptop) is not only cumbersome but also doesn't support blind operation.

[0052] In view of this, the present invention proposes a charging device for use between a receiving device 240 and a supporting surface 142. The receiving device 240 includes a main control circuit board 244 and a charging connection position 246, which may be a charging interface, a charging connector, or a charging contact, etc. (Refer to...) Figure 1 , 10 According to 12 and 16, in one embodiment of the present invention, the charging device includes:

[0053] Power supply structure 10 includes at least one power supply electrode group, the power supply electrode group including at least two power supply electrodes 11, the power supply electrodes 11 being used for electrical connection to an external power source such as a power socket, the power supply electrode group being exposed on the support surface 142; and

[0054] The power receiving structure 20 includes at least two power receiving electrodes 21, which are exposed on the power receiving device 240 and are used to electrically connect to the main control circuit board 244. The power receiving electrodes 21 can be electrically connected to the power supply electrodes 11.

[0055] In this invention, the two power supply electrodes 11 located on the support surface 142 serve as the positive terminal and the ground terminal (negative terminal), respectively, and are electrically connected to the two receiving electrodes 21 to form a circuit loop. Thus, when charging is required, the powered device 240 is simply placed on the support surface 142 so that the power supply electrodes 11 contact the receiving electrodes 21. At this time, the electrical energy from the external power source passes sequentially through the power supply electrodes 11 and the receiving electrodes 21 to supply power to the main control circuit board 244 and support the normal operation of the powered device 240. For example, the operating power of a laptop computer can be directly provided by an external power source, rather than necessarily by the rechargeable battery inside the laptop. Alternatively, the rechargeable battery can be charged via the main control circuit board 244, and then the rechargeable battery provides the power required for the laptop's operation. Compared with existing technologies, this power supply / charging operation is not only simpler to operate but also supports blind operation by the user, thereby improving the convenience of charging the powered device 240. For example, for laptops, users no longer need to search for the charging port 246 on the laptop every time, and align and insert the charging plug into the charging port 246, thus improving the user's charging experience.

[0056] Specifically, the support surface 142 can be a flat surface suspended in the air, such as a tabletop 142 of a tabletop 141, or it can be a floor or wall, such as a tiled floor. In the case where the power supply structure 10 is located on the ground, it is suitable for ground-based power receiving devices 240, such as intelligent devices (power receiving devices 240) like robot vacuums. Specifically, a receiving electrode 21 is provided on the bottom surface of the robot vacuum's casing, allowing it to automatically connect to the power supply electrode 11 and obtain electrical energy from it after moving to the area of ​​the power supply electrode 11 on the ground, thus significantly simplifying its charging operation. Alternatively, the power supply structure 10 can be located on a wall. For example, the power supply electrode 11 can be installed on the wall and close to the ground, with the receiving electrode 21 installed on the side of the robot vacuum. When the robot vacuum approaches the wall, the receiving electrode 21 will come into contact with the power supply electrode 11 on the wall to form a circuit, thereby realizing the charging function.

[0057] When the supporting surface 142 is the tabletop 142 of a table, that is, when the supporting component is a table, the technical solution of this invention is applicable to power-receiving devices 240 such as laptops, tablets, mobile phones, or smart speakers. A table can refer to an office desk, conference table, library desk, or restaurant table in a public setting, or a study desk, dining table, or dressing table in a home setting. It can also be a foldable tabletop 141 in a vehicle, such as the small tabletop 141 on the back of a high-speed train seat or the small tabletop 141 on the back of a car's front seat. Of course, besides these larger, less easily moved, or immovable structures, a table can also be a foldable, portable bedside desk. The following description will use a table and a laptop as examples. The laptop's casing 241 includes a bottom cover 242, on which power-receiving electrodes 21 are provided. Since the laptop needs a power adapter 14 to be charged, the power adapter 14 can be pre-installed on the table and connected to an external power source such as a power outlet. The power adapter 14 is connected to the power supply electrode 11, so the electrical energy obtained from the external power source passes through the power adapter 14, the power supply electrode 11, and the receiving electrode 21 in sequence to power the main control circuit board 244 of the laptop, thereby enabling the laptop to operate normally. This allows only the power supply electrode 11 to be exposed on the desktop 142, while other components such as the power adapter 14 and power cord are placed outside the desktop 142, for example, under the desk or on the side of the desk panel 141. This avoids the problem of a cluttered and untidy desktop 142 caused by placing the power adapter 14, power cord, etc. In other words, it avoids the problem of loose wires on the desktop, making the desktop cleaner.

[0058] It's worth noting that in public settings where laptops are used, such as on conference tables in meeting rooms or desks in libraries, the pre-installed power adapter 14 eliminates the need for users to carry a bulky power adapter 14, allowing for convenient mobile work or entertainment and enhancing the user experience. Similarly, in home settings, the system provides convenience for mobile laptop use. For example, power outlets 11 and power adapters 14 are provided on desks in studies, dining tables in restaurants, and dressing tables in bedrooms, enabling users to work remotely and switch locations freely without needing to carry the power adapter 14.

[0059] It is worth mentioning that, in the technical solution of this invention, the electrical connection between the power supply electrode 11 on the power supply structure 10 and the power receiving electrode 21 on the power receiving structure 20 enables wired charging of the powered device 240. This supports a larger charging power, thereby improving the charging efficiency of the charging process and meeting the usage requirements of powered devices 240 with high operating power, such as laptops. In other words, it allows for a wireless charging experience with the efficiency of wired charging.

[0060] It should be noted that the power supply electrode 11 and the power receiving electrode 21 can have various structural forms. For example, in one embodiment of the charging device, the power supply electrode 11 is configured as at least one of a conductive foil, a conductive sheet, a conductive film, a metallized plastic body, and a flexible circuit board. Specifically, the conductive foil can be copper foil, aluminum foil, etc.; the conductive sheet can be a metal sheet, a conductive plastic sheet, etc., such as a conductive silicone sheet, a conductive graphite sheet, a conductive foam sheet, etc.; the conductive film can be ITO (Indium-Tin Oxide) conductive film glass, ATO (Antimony Doped Tin Oxide) film, etc.; the metallized plastic body can be prepared by a process of metallizing the plastic surface or metallizing the entire plastic. Thus, by extending the power supply electrode 11, the area covered by the power supply electrode 11 can be increased, allowing the laptop to move within a certain range on the tabletop 141. That is, the receiving electrode 21 of the laptop can move within the area covered by the power supply electrode 11 while maintaining a contact electrical connection, thereby ensuring normal power supply to the laptop and improving the flexibility and convenience of the power supply plate 120. In other words, compared to wireless charging technology, this embodiment allows the laptop to have a greater range of movement on the desktop. Of course, in other embodiments, the power supply electrode can also be configured as a spring-loaded pin, etc.

[0061] In one embodiment of the charging device, the receiving electrode 21 is configured as at least one of a conductive foil, a conductive sheet, a conductive film, a metallized plastic body, and a flexible circuit board. Thus, by unfolding the receiving electrode 21, the area of ​​the bottom cover 242 covered by the receiving electrode 21 can be increased, allowing the laptop to move within a certain range on the tabletop 141. That is, the power supply electrode 11 can move within the area of ​​the bottom cover 242 covered by the receiving electrode 21 while maintaining a connection, thereby ensuring normal power reception for the laptop and improving the flexibility and convenience of the receiving plate 220. It should be noted that the connection between the power supply electrode and the receiving electrode does not specifically refer to their installation relationship, but includes the abutting relationship of the receiving electrode placed on the power supply electrode. Of course, in other embodiments, the receiving electrode can also be configured as a spring pin, etc.

[0062] Please refer to Figure 1 and 2 In one embodiment of the charging device, the power supply structure 10 further includes a power adapter 14, which is electrically connected to the power supply electrodes 11 and used for electrical connection to an external power source. Thus, providing the power adapter 14 to the user allows for convenient direct use of the power supply function of the power supply structure 10, saving the user the trouble of configuring and installing the power adapter 14, thereby improving the user experience. Of course, in other embodiments, the power supply socket can be the most basic configuration, while the power adapter can be an optional option for the user to choose from. That is, the user can either purchase only the power supply electrode assembly or purchase the power supply electrode assembly and power adapter together.

[0063] In one embodiment of the charging device, the power supply electrode group includes a first power supply electrode 111, a second power supply electrode 112, and a third power supply electrode 113 arranged at intervals between each other. The first power supply electrode 111 serves as the positive terminal, the second power supply electrode 112 serves as the ground terminal, and the third power supply electrode 113 serves as the signal terminal. Understandably, the power receiving structure 20 includes a first power receiving electrode 211, a second power receiving electrode 212, and a third power receiving electrode 213, and is respectively arranged in a one-to-one correspondence with the first power supply electrode 111, the second power supply electrode 112, and the third power supply electrode 113. Thus, by setting the third power supply electrode 113 as the signal terminal, the power adapter 14 can conveniently obtain the charging parameters of the powered device 240 directly via the power supply electrode 11. Of course, in some embodiments, the power supply electrode group may only include the first and second power supply electrodes, with the first power supply electrode serving as the positive terminal and the second power supply electrode serving as the ground terminal. In this case, carrier communication, load identification circuitry, or wireless communication can be used to enable the power adapter to obtain the charging parameters required during the laptop charging process. For example, the load identification circuit module can be located on the power supply structure or power adapter to negotiate the charging voltage, current, and other parameters of the powered device 90. Alternatively, the powered device can have a first wireless module, and the power supply structure or power adapter can have a second wireless module. The first and second wireless modules can achieve wireless communication to transmit the charging parameters of the powered device to the power adapter. Specifically, the wireless module can be any of the following: Wi-Fi (Wireless Fidelity), Bluetooth, 5G (5th generation mobile communication), or 4G (4th generation mobile communication).

[0064] In one embodiment of the charging device, optionally, the first power supply electrode 111 and the second power supply electrode 112 are spaced apart along a first direction, and the second power supply electrode 112 and the third power supply electrode 113 are spaced apart along a second direction, with the first and second directions intersecting. Specifically, in this embodiment, the first direction is configured as the width direction of the tabletop 141, and the second direction is configured as the length direction of the tabletop 141. Of course, in other embodiments, the first power supply electrode, the second power supply electrode, and the third power supply electrode may also be arranged spaced apart along the same direction.

[0065] In one embodiment of the charging device, optionally, the third power supply electrode 113 has the first power supply electrode 111 and the second power supply electrode 112 on opposite sides along its length. This allows the tabletop 141 covered by the three power supply electrodes 11 to have a wider area, facilitating the adaptation of the power supply electrode group to different sizes of powered devices 240, thereby improving the versatility of the power supply structure 10. It is understood that powered devices 240 of different sizes may have different positions and sizes of their powered electrodes 21. For example, laptops of different sizes may have different spacing between adjacent powered electrodes 21 on their bottom cover 242. Since the three power supply electrodes 11 of the power supply electrode group are laid out horizontally and spaced apart, effective contact electrical connection can be maintained when powered electrodes 21 with different spacing are placed on it, thus meeting the usage requirements of laptops of different sizes. Furthermore, it allows for slight movement of the powered device 240 on the tabletop 141 without affecting the normal operation of the power supply process, thereby improving the user experience.

[0066] To further improve the versatility of the power supply structure 10 and facilitate small-scale movement of the powered device 240 on the tabletop 141, in one embodiment of the charging device, optionally, the lengths of the first power supply electrode 111 and the second power supply electrode 112 are both smaller than the length of the third power supply electrode 113 in the width direction of the support surface 142. This allows the laptop to have a greater range of movement in the width direction of the desktop. Of course, in embodiments where the first, second, and third power supply electrodes are arranged sequentially and spaced apart along the length direction of the desktop, the lengths of the first, second, and third power supply electrodes can also be arranged to be roughly the same in the width direction of the desktop.

[0067] Please refer to Figure 7 and 8In one embodiment of the charging device, optionally, the first receiving electrode 211 and the second receiving electrode 212 are spaced apart along a first direction, and the second receiving electrode 212 and the third receiving electrode 213 are spaced apart along a second direction, with the first direction and the second direction intersecting. Of course, in other embodiments, the first receiving electrode, the second receiving electrode, and the third receiving electrode may also be arranged spaced apart along the same direction.

[0068] In one embodiment of the charging device, the power receiving structure 20 may optionally include a fourth power receiving electrode 214. The four power receiving electrodes 21 (including a first power receiving electrode 211, a second power receiving electrode 212, a third power receiving electrode 213, and a fourth power receiving electrode 214) are arranged in a rectangular pattern with their corners spaced apart. Specifically, in this embodiment, the first power receiving electrode 211 and the second power receiving electrode 212 are located on the left side of the laptop, and the third power receiving electrode 213 and the fourth power receiving electrode 214 are located on the right side of the laptop. The third power receiving electrode 213 and the fourth power receiving electrode 214 are electrically connected and serve as a signal terminal. Thus, the four power receiving electrodes 21 are arranged in a rectangular pattern with their corners spaced on the bottom cover 242 of the laptop, which can prevent the laptop from being placed unevenly. Furthermore, the bottom cover 242 of the laptop usually has four protruding feet 243, and the four power receiving electrodes 21 can be optionally attached to the four protruding feet 243 to improve the stability of the laptop. Understandably, the third power supply electrode 113 on the tabletop 141 is simultaneously positioned corresponding to both the third power receiving electrode 213 and the fourth power receiving electrode 214. This increases the contact area of ​​the signal terminal, allowing the laptop's signal terminal to move within a certain range on the tabletop 141, thereby improving the flexibility of the charging operation. Of course, in some embodiments, the number of power receiving electrodes can be 5, 6, 8, etc., and the specific number is not limited. In other embodiments, the third and fourth power receiving electrodes can be electrically connected and serve as the positive terminal together, while the first and second power receiving electrodes serve as the signal terminal and ground terminal, respectively; or the third and fourth power receiving electrodes can be electrically connected and serve as the ground terminal together, while the first and second power receiving electrodes serve as the signal terminal and positive terminal, respectively.

[0069] In one embodiment of the charging device, optionally, the power supply electrode 11 is arranged in a planar shape, and the receiving electrode 21 is arranged in a point shape. It should be noted that "point shape" means that the contact area of ​​the point structure on the planar structure is much smaller than the area of ​​the planar structure; that is, it is a relative size relationship. Therefore, "point shape" does not specifically refer to a single small contact point. Thus, compared to when both the power supply electrode and the receiving electrode are arranged in a point shape, in this embodiment, the laptop does not need to be precisely positioned on the desktop for the power supply electrode and the receiving electrode to make contact. In other words, the laptop can be charged simply by placing it on a desktop. Furthermore, this reduces the amount of material used for the power supply electrode or the receiving electrode, thereby saving manufacturing costs. Of course, in other embodiments, both the power supply electrode and the receiving electrode can be arranged in a planar shape; or, the power supply electrode can be arranged in a point shape, and the receiving electrode in a planar shape.

[0070] Understandably, the power supply structure 10 can take many forms. For example, please refer to... Figure 1 and 2 In one embodiment of the power supply structure 10, the power supply structure 10 is configured as a power supply sheet 120. The power supply sheet 120 includes a power supply base film 121 and power supply electrodes 11 disposed on the power supply base film 121. The power supply sheet 120 is fixed to the desktop 142 of the tabletop 141 using adhesive, screws, or nails. The power adapter 14 is disposed on the side or bottom surface of the tabletop 141. Specifically, the power supply base film 121 has a first mounting surface (not shown in the figures) and a second mounting surface 121a. The first mounting surface is used to mount on the desktop 142, and the power supply electrodes 11 are located on the second mounting surface 121a. It should be noted that the power supply base film 110 may include a power supply film body with two power supply electrodes 11, and the user can directly install one power supply film body. Alternatively, the power supply base film 110 may include at least two separately disposed power supply film bodies, with only one power supply electrode 11 on each power supply film body. The user needs to purchase and install at least two independent power supply film bodies to obtain at least two power supply electrodes 11. In this way, by placing multiple power supply electrodes on the same power supply film body, it is not only convenient to produce, store, manage, transport and sell the power supply sheet 10, thereby reducing the production cost of the power supply sheet 10, but also convenient for users to store and attach the power supply sheet 10 product, thereby improving the user experience.

[0071] For example, please refer to Figure 3 and 4In another embodiment of the power supply structure 10, the power supply structure 10 is configured as a power supply socket 130. The power supply socket 130 includes a power supply socket body 131 and at least two power supply electrodes 11 disposed on the power supply socket body 131. The power supply socket 130 can be placed or embedded in a tabletop 141. The power adapter 14 is disposed on the side or bottom surface of the tabletop 141. Specifically, the socket body has a power supply surface 131a, and the power supply electrodes are disposed on the power supply surface 131a. The power supply structure 10 also includes an electrical connection portion 13 electrically connected to the power supply electrodes 11. The electrical connection portion 13 is used to electrically connect to the power adapter 14. The electrical connection portion 13 can be a conductive wire, connector, or terminal block, etc., as long as it can achieve connection with the power adapter 14.

[0072] For example, please refer to Figure 5 and 6 In another embodiment of the power supply structure 10, the power supply structure 10 is configured as a power supply table 140. The power supply table 140 includes a table and at least two power supply electrodes 11 disposed on a tabletop 141 of the table. The tabletop 142 of the tabletop 141 is configured as a support surface 142. The power adapter 14 is disposed on the side or bottom surface of the tabletop 141.

[0073] In one embodiment of the power supply structure 10, the first mounting surface (not shown in the figures) is further provided with adhesive (not shown in the figures) at least partially, and the power supply piece 120 also includes a release film (not shown in the figures), which at least covers the area of ​​the adhesive on the first mounting surface. Thus, by having the power supply piece 120 come with its own adhesive, the user can conveniently use the power supply piece 120 product. Specifically, after purchasing the power supply piece 120 product, the user only needs to peel off the release film and then attach the first mounting surface with adhesive to the desktop 142. In this embodiment, the first mounting surface can be provided with adhesive throughout the entire edge area, thereby preventing the power supply piece 120 from easily warping after being attached to the desktop 141. Alternatively, the entire first mounting surface area can be provided with adhesive, thereby enhancing the connection strength between the power supply piece 120 and the desktop 141, preventing the power supply piece 120 from accidentally detaching, and thus improving the user experience. Of course, in other embodiments, the power supply piece can also be mounted on the desktop using Velcro, thumbtacks, nails, or screws.

[0074] In one embodiment of the power supply structure 10, the power supply electrode 11 and the power supply base film 121 are optionally integrally formed by hot pressing. This ensures the connection strength between the power supply electrode 11 and the power supply base film 121, preventing the power supply electrode 11 from accidentally detaching from the power supply base film 121 during use, thereby improving the service life of the power supply sheet 120. It is worth mentioning that the hot pressing process technology is mature and therefore has the advantage of a high yield rate. Of course, in other embodiments, the power supply electrode can also be bonded and fixed to the power supply base film.

[0075] Please refer to Figure 1 and 2 In one embodiment of the power supply structure 10, the power supply structure 10 further includes an electrical connection portion 13 electrically connected to the power supply electrode 11. The electrical connection portion 13 is used to electrically connect to the power adapter 14. The power supply sheet 120 also includes a power supply connection circuit 12 connected between the power supply electrode 11 and the electrical connection portion 13. The power supply connection circuit 12 is disposed on the second mounting surface 121a of the power supply base film 121. Specifically, the power supply connection circuit 12 can be configured as a conductive wire, conductive foil, conductive sheet, conductive film, or flexible circuit board, etc., and the electrical connection portion 13 can be a conductive wire, connector, or terminal block, etc., as long as it can be connected to the power adapter 14. In this way, by disposing of the power supply connection circuit 12 on the second mounting surface 121a, the structure of the power supply connection circuit 12 will not affect the tight fit between the first mounting surface and the tabletop 141, thereby improving the connection strength between the power supply sheet 120 and the tabletop 141. Secondly, it is understandable that if the power supply connection circuit 12 is located on the first mounting surface, the power supply base film 121 needs to have an opening so that the power supply electrode 11 on the second mounting surface 121a can connect with the power supply connection circuit 12 on the first mounting surface. In this embodiment, since both the power supply connection circuit 12 and the power supply electrode 11 are located on the second mounting surface 121a and can be directly connected, the power supply base film 121 does not need to have an opening. This reduces the manufacturing cost of the power supply base film 121 and simplifies the connection operation between the power supply connection circuit 12 and the power supply electrode 11, thereby improving the production efficiency of the power supply sheet 120. Of course, in other embodiments, the power supply connection circuit can also be located on the first mounting surface.

[0076] In one embodiment of the power supply structure 10, optionally, the tabletop 141 also has a supporting bottom surface (not shown in the figures) opposite to the supporting surface 142, and a supporting side surface (not shown in the figures) connecting the supporting surface 142 and the supporting bottom surface. The power supply piece 120 includes a first membrane segment 120a, a second membrane segment 120b, and a third membrane segment 120c connected in sequence. The first membrane segment 120a is mounted on the supporting surface 142, the second membrane segment 120b is mounted on the supporting side surface, and the third membrane segment 120c is mounted on the supporting bottom surface. The power supply electrode 11 is located in the first membrane segment 120a, the electrical connection part 13 is located in the third membrane segment 120c, and the power supply connection circuit 12 is at least partially located in the second membrane segment 120b and the third membrane segment 120c. In this way, the main structure of the power supply piece 120 can be hidden on the side and bottom surfaces of the tabletop 141, keeping the front of the tabletop 141 as clean as possible, thereby improving the user experience.

[0077] Please refer to Figure 3 and 4In another embodiment of the power supply structure 10, optionally, the power supply base body 131 includes a sub-block, and the three power supply electrodes—the first power supply electrode 211, the second power supply electrode 212, and the third power supply electrode 213—are all located on the sub-block. Thus, by placing the three power supply electrodes on the same sub-block (power supply base body 131), it facilitates the production, warehousing management, transportation, and sales of the power supply base 130, thereby reducing the production cost of the power supply base 130, and also facilitates user storage and use of the power supply base 130 product, thereby improving the user experience. Of course, in other embodiments, the base body includes at least two separately arranged sub-blocks, with at least two power supply electrodes located on different sub-blocks. For example, the base body includes three sub-blocks, with the first power supply electrode located on one sub-block, the second power supply electrode on another sub-block, and the third power supply electrode on yet another sub-block.

[0078] In another embodiment of the power supply structure 10, the power supply surface 131a is further disposed on the front side of the power supply base body 131, and the power supply surface 131a is used for placing the power receiving device 240. In this way, the weight of the power receiving device 240 itself can be used to press the power receiving electrode 21 onto the power supply electrode 11, so that the two maintain an effective contact relationship and ensure effective connection of the circuit loop. Of course, in some embodiments, a clearance groove is provided on the front side of the power supply base body 131, and the power supply surface is located on the bottom wall or side wall of the clearance groove. The power receiving electrode on the power receiving device is configured as a columnar structure, such as a spring pin, so that the power receiving electrode can extend into the clearance groove and abut against the power supply electrode inside the groove. In other embodiments, the power supply surface is disposed on the side side of the power supply base body 131.

[0079] In another embodiment of the power supply structure 10, optionally, the power supply electrode 11 is bonded to the power supply surface 131a. This facilitates the installation of the power supply electrode 11 and the power supply base body 131, thereby improving the production efficiency of the power supply base 130 and reducing manufacturing costs. Of course, in some embodiments, the power supply electrode may be embedded in the power supply surface, or the power supply surface may have a groove in which the power supply electrode is embedded and bonded. This prevents the power supply electrode from shifting on the power supply surface, ensuring it remains in the correct position. In other embodiments, the power supply base also includes a retaining ring, with the power supply electrode at least partially exposed in the inner hole of the retaining ring and at least partially sandwiched between the retaining ring and the power supply surface. This avoids the problem of harmful substances such as formaldehyde volatilizing due to the use of adhesives and facilitates the disassembly and replacement of damaged power supply electrodes. In still other embodiments, the power supply electrode and the base body are integrally formed by thermoforming. This ensures the connection strength between the power supply electrode and the base body, preventing the power supply electrode from accidentally detaching from the base body during use, thereby improving the service life of the power supply base.

[0080] In another embodiment of the power supply structure 10, the power supply base body 131 further includes a base bottom surface opposite to the power supply surface 131a. The power supply base 130 also includes a power supply connection circuit 12 connected between the power supply electrode 11 and the electrical connection portion 13. The power supply connection circuit 12 is disposed within the power supply base body 131 or on the base bottom surface. Specifically, the power supply surface 131a has a wire-passing hole 131b corresponding to the power supply connection circuit 12, allowing the power supply connection circuit 12 to pass through the wire-passing hole 131b and extend into the power supply base body 131 or on the base bottom surface. The power supply connection circuit 12 is configured as at least one of a conductive wire, conductive foil, conductive sheet, conductive film, and flexible circuit board. This avoids the problem of damage caused by long-term exposure of the power supply connection circuit 12, thus protecting the power supply connection circuit 12 and improving the service life of the power supply base 130. Of course, in some embodiments, the power supply connection circuit may be disposed on the power supply surface, and the power supply base may also include a protective film or pad covering the power supply connection circuit. In other embodiments, the power supply connection circuit may be located on the power supply surface and extend from the power supply electrode to the side of the power supply base body. The side of the power supply base body is provided with a wire groove, through which the power supply connection circuit passes and extends to the bottom surface of the power supply base body.

[0081] In another embodiment of the power supply structure 10, the power supply base body 131 is further configured as an insulating material, or an insulating structure is sandwiched between the power supply electrode 11 and the power supply surface 131a. Specifically, the insulating material can be rubber, plastic, glass, ceramic, mica, or asbestos, etc., and the insulating structure can be insulating glue, insulating varnish, insulating silicone grease, insulating film 245, plastic sheet, or ceramic sheet, etc. In this way, the problem of short circuit caused by electrical connection between different power supply electrodes 11 can be avoided, so as to ensure the normal power supply operation of the power supply base 130. Of course, in other embodiments, the base body can also be configured as an insulating material, and an insulating structure can be sandwiched between the power supply electrode and the power supply surface; or, the power supply electrode itself has an insulating structure. For example, in the embodiment where the power supply electrode is configured as a flexible circuit board, since the substrate of the flexible circuit board is an insulating material, the substrate can be directly mounted on the base body, and the power supply electrode on it can be isolated from the base body. In this way, the material of the base body is not specifically limited.

[0082] In another embodiment of the power supply structure 10, the power supply base 130 further includes a magnetic attractor (not shown in the figures), which is disposed on the power supply base body 131. Specifically, the magnetic attractor can be a magnetic structure with magnetic material, such as a magnetic body made of ferrite, neodymium iron boron, or samarium cobalt, or it can be an electromagnet structure. In this embodiment, four magnetic attractors are provided and are disposed at the four corners of the power supply base body 131, and the power supply electrode 11 is disposed in the area enclosed by the four magnetic attractors. In this way, the operation of the power supply electrode 11 in the central area is not affected, and a stable and reliable magnetic attraction force is provided to attract the magnetically attached device 240, thereby improving the stability of the device 240 on the power supply base 130. It should be noted that the power receiving device 240 can have its housing 241 made of a magnetic material, such as the bottom cover 242 of a laptop computer. Alternatively, it can be a magnetic structure with adhesive, such as a magnet, provided to the user or purchased by the user. The magnetic structure is then attached to the bottom surface of the power receiving device 240 with the corresponding magnetic attachment on the power supply base 130 to generate a magnetic force with the magnetic attachment. Of course, in other embodiments, the power supply base may also include a suction cup, which is located on the base body.

[0083] The power supply socket 130 can be placed directly on the tabletop 141 and moved freely on the desktop 142, or it can be embedded in the tabletop 141. For example, in another embodiment of the power supply structure 10, optionally, embedded structures (not shown in the figures) are provided on opposite sides of the power supply socket body 131, which are used to embed and connect to the tabletop 141. In this way, the installation reliability and stability of the power supply socket 130 on the table can be improved, and the upper surface of the power supply socket 130 can be smoothly transitioned to the desktop 142, making the desktop 142 look cleaner and flatter, and improving the user experience.

[0084] In another embodiment of the power supply structure 10, optionally, the tabletop 141 is provided with a storage groove (not shown in the attached drawings) corresponding to the power supply base body 131. The storage groove penetrates one side of the tabletop 141 and forms a sliding entrance. The power supply base body 131 of the power supply base 130 is provided with an embedding structure on opposite side edges. The storage groove is provided with a guide structure corresponding to the embedding structure, and the two guide structures are respectively provided on opposite sides of the sliding entrance. Specifically, in this embodiment, the embedding structure is configured as an embedded rib, and the guide structure is configured as a sliding groove. In this way, it is convenient to install and disassemble the power supply base 130, thereby facilitating cleaning, maintenance, and replacement of the power supply base 130. Moreover, after the power supply base 130 is installed in place, the cooperation structure of the embedded rib and the sliding groove can play a limiting role to prevent the power supply base 130 from moving freely in the vertical direction, thereby improving the installation stability of the power supply base 130. Of course, in other embodiments, the tabletop may have a storage groove corresponding to the seat body, the embedding structure may be configured as a buckle, the side wall of the storage groove may have a corresponding slot for the buckle, the buckle may be placed in the slot, and the seat body may be at least partially located in the storage groove.

[0085] Please refer to Figure 5 and 6 In another embodiment of the power supply structure 10, the power supply electrode 11 is further disposed on the tabletop 142 (front) of the tabletop 141. In this way, the weight of the receiving device 240 itself can be used to press the receiving electrode 21 onto the power supply electrode 11, ensuring effective contact between the two and guaranteeing effective circuit continuity. Of course, in some embodiments, a clearance groove is provided on the front of the tabletop, and the power supply electrode is located on the bottom or side wall of the clearance groove. The receiving electrode on the receiving device is configured as a columnar structure, such as a spring-loaded pin, so that the receiving electrode can extend into the clearance groove and abut against the power supply electrode inside the groove. In other embodiments, the power supply electrode is disposed on the side of the tabletop.

[0086] In another embodiment of the power supply structure 10, optionally, the power supply electrode 11 is embedded in the desktop 142. Specifically, in this embodiment, the desktop 141 has a groove 142a. After the power supply electrode 11 is embedded in the groove 142a, its upper surface and the desktop 142 present a smooth transition. This avoids the problem of the receiving electrode 21 of the power receiving device 240 hitting the protruding or recessed structure when sliding on the desktop 142, thus preventing the movement from being uneven. It also avoids the problem of the edge of the power supply electrode 11 being easily bumped and warped, thereby improving the service life of the power supply table 140. Specifically, the power supply electrode 11 can be fixed in the groove 142a by adhesive bonding, or the power supply electrode 11 can be embedded in the groove 142a by interference fit. Of course, in some embodiments, the power supply electrode can also be directly bonded to the desktop. This facilitates the installation of the power supply electrode and the desktop, thereby improving the production efficiency of the power supply table and reducing manufacturing costs. In other embodiments, the power supply table also includes a retaining ring, with the power supply electrode at least partially exposed within the inner hole of the retaining ring and at least partially clamped between the retaining ring and the tabletop. This avoids the problem of harmful substances such as formaldehyde evaporating due to the use of adhesives and facilitates the disassembly and replacement of damaged power supply electrodes. In still other embodiments, the power supply electrode and the tabletop are integrally formed by thermoforming. This ensures the connection strength between the power supply electrode and the tabletop, preventing the power supply electrode from accidentally detaching from the tabletop during use, thereby extending the lifespan of the power supply table.

[0087] In another embodiment of the power supply structure 10, the power supply structure 10 further includes an electrical connection portion 13 electrically connected to the power supply electrode 11, and a power supply connection circuit 12 connected between the power supply electrode 11 and the electrical connection portion 13. The electrical connection portion 13 is used to electrically connect to the power adapter 14, and the power supply connection circuit 12 is disposed inside the tabletop 141 or on the bottom surface of the tabletop 141. Specifically, the tabletop 142 is provided with a wire-passing hole 131b (not shown in the figures) corresponding to the power supply connection circuit 12, so that the power supply connection circuit 12 passes through the wire-passing hole 131b and extends into the tabletop 141 or on the bottom surface of the tabletop 141. The power supply connection circuit 12 is configured as at least one of a conductive wire, a conductive foil, a conductive sheet, a conductive film, and a flexible circuit board. In this way, the problem of damage caused by long-term exposure of the power supply connection circuit 12 can be avoided, thus protecting the power supply connection circuit 12 and improving the service life of the power supply table 140. Of course, in other embodiments, the power supply connection circuit can also be disposed on the tabletop, and the power supply table also includes a protective film or pad covering the power supply connection circuit. It should be noted that the electrical connection part can be a conductive wire, connector, or terminal block, as long as it can be connected to the power adapter.

[0088] In another embodiment of the power supply structure 10, the tabletop 141 may optionally be made of an insulating material, or an insulating structure may be sandwiched between the power supply electrode 11 and the tabletop 142. This avoids short circuits caused by electrical connections between different power supply electrodes 11, ensuring the normal power supply operation of the power supply table 140. Of course, in other embodiments, the tabletop may also be made of an insulating material, with an insulating structure sandwiched between the power supply electrode and the front of the seat; or, the power supply electrode itself may have an insulating structure. For example, in an embodiment where the power supply electrode is configured as a flexible circuit board, since the substrate of the flexible circuit board is an insulating material, the substrate can be directly mounted on the tabletop, isolating the power supply electrode on it from the tabletop. Thus, the material of the tabletop is not specifically limited.

[0089] In another embodiment of the power supply structure 10, the power supply table 140 further includes a wireless charging coil (not shown in the accompanying drawings) and a wireless charging circuit board (not shown in the accompanying drawings) electrically connected to the wireless charging coil. The wireless charging coil is disposed on the tabletop 141. Thus, the power supply table 140 can also provide users with wireless charging functionality, allowing users to choose between wired or wireless charging methods, or both simultaneously, thereby improving the ease of use and flexibility of the power supply table 140.

[0090] In another embodiment of the power supply structure 10, the power supply table 140 further includes a rechargeable battery (not shown in the figures), which is electrically connected to a wireless charging coil. This allows the power supply table 140 to be moved freely, thus enriching its usage scenarios. For example, when the power supply table 140 is configured as a portable bedside desk, the user can use the power in the rechargeable battery to power a laptop, and the use of the laptop is not limited by whether there is an external power source in the surrounding environment; for example, the user can freely and for a long time use the laptop on a lawn in a park.

[0091] In another embodiment of the power supply structure 10, optionally, the wireless charging coil is disposed inside the tabletop 141 or on the bottom surface of the tabletop 141, and the wireless charging circuit board is disposed on the bottom surface of the tabletop 141. This avoids the problem of the wireless charging coil being damaged due to long-term exposure, thus protecting the wireless charging coil and extending the service life of the power supply table 140. Secondly, it effectively conceals the wireless charging coil and the wireless charging circuit board, thereby improving the tidiness of the desktop 142. Of course, in other embodiments, the wireless charging coil can also be disposed on the desktop, and the power supply table may also include a protective film or pad covering the wireless charging coil.

[0092] In another embodiment of the power supply structure 10, optionally, the power supply table 140 is provided with at least two power supply electrode groups, which are spaced apart along the length of the tabletop 141. Thus, the power supply table 140 can provide power to at least two powered devices 240, thereby improving the ease of use of the power supply table 140. In particular, the power supply table 140 in this embodiment is very suitable for public scenarios, such as conference tables in meeting rooms, allowing multiple people and multiple laptops to share multiple power supply electrode groups on a single table. Of course, in this embodiment, optionally, at least two power supply electrode groups can also be spaced apart along the width of the tabletop 141, allowing users to select any power supply electrode group as needed, thereby further improving the ease of use of the power supply stand 130.

[0093] In another embodiment of the power supply structure 10, the power supply electrode group further includes at least one power supply switch (not shown in the figures), which corresponds one-to-one with and is electrically connected to the power supply electrode group. Specifically, the power supply switch can be an external switch located on the table for user operation, such as a mechanical switch or a touch switch, allowing the user to choose whether to activate the charging function of the power supply table 140 according to their needs. The power supply switch can also be a built-in switch located in the power supply structure 10, such as an electromagnetic switch or an inductive switch, which automatically turns on after sensing that the laptop is placed on the power supply electrode 11, or is automatically turned on under the control of the management terminal, so as to provide charging function to the user.

[0094] In another embodiment of the power supply structure 10, the power supply table 140 further includes at least one power adapter 14, which is electrically connected to at least two power supply electrode groups. The power adapter 14 has a communication function. Specifically, the power adapter 14 with the communication function can communicate with a management terminal to enable or disable each power supply electrode group, thereby achieving control over multiple power supply electrode groups. In this embodiment, the communication function of the power adapter 14 is wireless communication, such as through a Wi-Fi module, Bluetooth module, 5G module, or 4G module. It is understood that the management terminal has management platform software that can remotely control the conduction state of each power supply switch. It is worth mentioning that when the power adapter 14 supplies power to each power supply electrode group one-to-one, the power adapter 14 may not be configured with a communication function. Of course, in other embodiments, the communication function of the power adapter can also be connected to the management terminal through a conductive wire structure, that is, in the form of wired communication.

[0095] In one embodiment, optionally, the bottom surface of the tabletop 141 is provided with a mounting groove for mounting the power adapter 14. Specifically, in this embodiment, a mounting bracket is mounted on the bottom surface of the tabletop 141. The mounting bracket has a C-shaped structure, and its opening is parallel to the extension direction of the bottom surface of the tabletop 141. The mounting bracket and the bottom surface of the tabletop 141 together define a mounting groove, in which the power adapter 14 can be inserted. In this way, the mounting groove structure can provide support for the power adapter 14, avoiding the risk of accidental detachment between the electrical connection part 13 and the power adapter 14 due to the power adapter 14 being suspended in the air. That is, the connection between the electrical connection part 13 and the power adapter 14 can be guaranteed. Secondly, the power adapter 14 can be effectively concealed, thereby improving the tidiness of the desktop. Of course, in some embodiments, a mounting groove can also be provided on the side of the tabletop for inserting the power adapter. In other embodiments, the side of the table is provided with a drawer, and the drawer panel is provided with a clearance opening corresponding to the conductive wire of the power adapter, so that the power adapter can be placed in the drawer.

[0096] In one embodiment, optionally, the power adapter 14 includes a body and a power plug. The body of the power adapter 14 includes a chip, a heat sink, etc. The body of the power adapter 14 is completely integrated into the tabletop 141, leaving only the power plug exposed for the user to plug into a power outlet to obtain external power. In this way, the body of the power adapter can be protected, and the appearance of the tabletop can be made more concise.

[0097] In another embodiment of the power supply structure 10, the charging device further includes a short-circuit protection module (not shown in the figures) electrically connected to the power supply electrode group and an overvoltage protection module (not shown in the figures) electrically connected to the power receiving electrode group. Specifically, in this embodiment, the short-circuit protection module can be installed on the power supply electrode group or the power adapter, and the overvoltage protection module can be installed on the power receiving electrode group, the power receiving socket, or the power receiving device. Thus, when abnormal problems such as short circuits, output voltage overloads, or undervoltage occur during the power supply to the power receiving device 240, the power receiving device 240 and the power supply table 140 can be protected from damage, thereby providing protection for both the power receiving device 240 and the power supply table 140. Furthermore, the abnormal information can be sent to the management terminal via the communication module so that the administrator is aware of it and it can be recorded for inspection.

[0098] Of course, the power receiving structure 20 can take many forms. It can be independent of the power receiving device 240 and be mounted on the power receiving device 240; or it can be directly mounted on the power receiving device 240, meaning the power receiving structure 20 is part of the power receiving device 240. It should be noted that the power receiving device 240 typically has a charging connection position 246, which can specifically be a charging interface 246, a charging connector, or act as a contact point, etc. On laptops, a common type is the charging interface 246. Please refer to... Figures 7 to 9 In one embodiment of the power receiving structure 20, the power receiving structure 20 is configured as a power receiving sheet 220. The power receiving sheet 220 includes a power receiving base film 221, a power receiving electrode 21 disposed on the power receiving base film 221, and an adapter 23c electrically connected to the power receiving electrode 21. The adapter 23c is used to install and electrically connect to the charging interface 246 of the laptop computer. The power receiving sheet 220 is attached to the bottom surface of the laptop computer with the power receiving electrode 21 exposed downwards. In this way, an external power source sequentially supplies power to the laptop computer through the power adapter 14, the power supply electrode 11, the power receiving electrode 21, the adapter 23c, and the charging interface 246. Specifically, the power receiving base film 221 has a third mounting surface (not shown in the figures) and a fourth mounting surface 221a. The third mounting surface is used to mount on the power receiving device 240, and the power receiving electrode 21 is located on the fourth mounting surface 221a. Of course, in other embodiments, the power receiving sheet can also be attached to the side or top surface of the power receiving device.

[0099] For example, please refer to Figures 10 to 14 In another embodiment of the power receiving structure 20, the power receiving structure 20 is configured as a power receiving base 230. The power receiving base includes a power receiving base body 231231, a power receiving electrode 21 disposed on the power receiving base body 231231, and an adapter 23c electrically connected to the power receiving electrode 21. The adapter 23c is used to install and electrically connect to the charging interface 246 of the laptop computer. In this way, the external power supply sequentially supplies power to the laptop computer through the power adapter 14, the power supply electrode 11, the power receiving electrode 21, the adapter 23c, and the charging interface 246.

[0100] For example, please refer to Figures 15 to 20In another embodiment of the power receiving structure 20, the power receiving device 240 itself has a power receiving electrode 21. Specifically, for example, the power receiving electrode 21 is provided on the bottom cover 242 of a laptop computer, the main control circuit board 244 is provided inside the housing 241, and a connection circuit connecting the power receiving electrode 21 and the main control circuit board 244 is provided. The external power supply sequentially passes through the power adapter 14, the power supply electrode 11, the power receiving electrode 21, and the main control circuit board 244 to supply power to the laptop computer. Of course, in some embodiments, the power receiving electrode can be independent of the laptop computer and fixed to the bottom cover of the laptop computer by pasting or welding, for example, when the power receiving electrode is configured as a conductive sheet, conductive film, or flexible circuit board. In other embodiments, the power receiving electrode is provided on the side wall or top wall of the power receiving device.

[0101] Please refer to Figures 7 to 9 In one embodiment of the power receiving structure 20, optionally, the power receiving base film 221 includes a power receiving film body, on which the first power receiving electrode 211, the second power receiving electrode 212, the third power receiving electrode 213, and the fourth power receiving electrode 214 are all disposed. This facilitates the production, warehousing, transportation, and sales of the power receiving sheet 10, thereby reducing the production cost of the power receiving sheet 10, and also makes it convenient for users to store and attach the power receiving sheet 10, thereby improving the user experience. Of course, in other embodiments, the power receiving base film may include at least two separately disposed power receiving film bodies, with only one power receiving electrode on each body. Users can then purchase at least two independent power receiving film bodies and adjust the distance and relative position of the multiple power receiving electrodes by adjusting the attachment positions of the different power receiving film bodies on the bottom cover of the laptop.

[0102] In one embodiment of the power receiving structure 20, optionally, the power receiving plate 220 is mounted on the bottom surface of the power receiving device 240, and the power receiving electrode 21 is exposed on the bottom surface of the power receiving device 240. This facilitates the alignment of the power receiving electrode 21 on the laptop with the power supply electrode 11 on the desktop 142, thereby facilitating the laptop's charging operation. The weight of the laptop and the power receiving stand 230 ensures that the power receiving electrode 21 is continuously and effectively held against the power supply electrode 11, preventing accidental detachment and potential charging malfunctions. Alternatively, in other embodiments, the power receiving electrode can be located on the side wall of the power receiving device to cooperate with a power supply electrode located on the wall. For example, the power supply plate is mounted on the wall and positioned close to the ground, and the power receiving plate is attached to the side wall of the robot vacuum cleaner, with the power receiving electrode exposed on the side. When the robot vacuum cleaner approaches the wall, the power receiving electrode comes into contact with the power supply electrode on the wall to form a circuit, thereby achieving the charging function.

[0103] In one embodiment of the power receiving structure 20, the power receiving electrode 21 and the power receiving base film 221 are optionally integrally formed by thermoforming. This ensures the connection strength between the power receiving electrode 21 and the power receiving base film 221, preventing the power receiving electrode 21 from accidentally detaching from the power receiving base film 221 during use, thereby improving the service life of the power receiving sheet 220. It is worth mentioning that the thermoforming process is a mature technology, offering the advantage of a high yield rate. Of course, in other embodiments, the power receiving electrode can also be bonded and fixed to the power receiving base film.

[0104] In one embodiment of the power receiving structure 20, optionally, the middle portion of the power receiving electrode 21 protrudes in a direction away from the fourth mounting surface 221a, and a groove 231a is formed on the side of the protruding portion near the fourth mounting surface 221a. Specifically, in this embodiment, both the protruding surface and the groove 231a of the power receiving electrode 21 are arc-shaped, for example, spherical or nearly spherical. The groove 231a of the power receiving electrode 21 can adapt to the protruding foot 243 of the laptop, thereby facilitating the conformal attachment of the power receiving electrode 21 to the protruding foot 243, so that the power receiving electrode 21 fits better against the bottom cover 242, avoiding the problem that the power receiving electrode 21 is easily detached from the bottom cover 242 due to edge wrinkles.

[0105] In one embodiment of the power receiving structure 20, the third mounting surface is further provided with adhesive (not shown in the figures) at least partially, and the power receiving sheet 220 also includes a release film (not shown in the figures), which at least covers the area on the third mounting surface where the adhesive is located. Thus, by having the power receiving sheet 220 come with its own adhesive, the user can conveniently use the power receiving sheet 220 product. Specifically, after purchasing the power receiving sheet 220 product, the user only needs to peel off the release film and then attach the third mounting surface with adhesive to the power receiving device. In this embodiment, the third mounting surface can be provided with adhesive throughout its entire edge area, thereby preventing the power receiving sheet 220 from easily warping after being attached to the power receiving device. Alternatively, the entire third mounting surface area can be provided with adhesive, thereby enhancing the connection strength between the power receiving sheet 220 and the power receiving device, preventing the power receiving sheet 220 from accidentally detaching, and thus improving the user experience. Of course, in other embodiments, the power receiving sheet can also be installed on the power receiving device by means of Velcro, tacks, nails, or screws.

[0106] In one embodiment of the power receiving structure 20, the power receiving base film 221 may optionally be made of an insulating material. This avoids short circuits caused by electrical connections between different power receiving electrodes 21, thus ensuring the normal power receiving operation of the power receiving sheet 220. Specifically, when the bottom cover 242 of the laptop is made of metal, the power receiving base film 221 in this embodiment effectively isolates the power receiving electrodes 21 from the metal bottom cover 242. Of course, if the bottom cover 242 of the laptop is made of an insulating material, such as a plastic bottom cover 242, the material of the power receiving base film 221 is not specifically limited. In some embodiments, an insulating structure may be sandwiched between the power receiving electrode and the fourth mounting surface. In other embodiments, the power receiving base film is made of an insulating material, and an insulating structure is sandwiched between the power receiving electrode and the fourth mounting surface.

[0107] In one embodiment of the power receiving structure 20, optionally, the side edge of the power receiving base film 221 extends beyond the side edge of the power receiving electrode 21. This ensures that the power receiving base film 221 effectively isolates the power receiving electrode 21 from the bottom cover 242 of the laptop, preventing accidental electrical connections between different power receiving electrodes 21 due to contact with the conductive bottom cover 242, thus avoiding short circuits. Of course, in other embodiments, the side edge of the power receiving base film may be flush with the side edge of the power receiving electrode, or slightly shorter than the side edge of the power receiving electrode.

[0108] In one embodiment of the power receiving structure 20, the power receiving sheet 220 may optionally include a power receiving connection circuit 22 connected between the power receiving electrode 21 and the adapter 23, the power receiving connection circuit 22 being disposed on the fourth mounting surface 221a. Specifically, the power receiving connection circuit 22 may be configured as at least one of a conductive foil, a conductive sheet, a conductive film, and a flexible circuit board. Thus, utilizing a power receiving connection circuit 22 structure with a smaller thickness facilitates the thinner design of the power receiving sheet 220, thereby avoiding a significant impact on the thickness of the laptop computer. Of course, in other embodiments, the power receiving connection circuit may also be configured as a conductive line.

[0109] In one embodiment of the power receiving structure 20, the power receiving connection circuit 22 and the power receiving base film 221 are optionally integrally formed by thermoforming. This ensures the connection strength between the power receiving connection circuit 22 and the power receiving base film 221, preventing the power receiving connection circuit 22 from accidentally detaching from the power receiving base film 221 during use, thereby improving the service life of the power receiving sheet 220. It is worth mentioning that the thermoforming process technology is mature and therefore has the advantage of a high yield rate. Of course, in other embodiments, the power receiving connection circuit can also be bonded and fixed to the power receiving base film.

[0110] In one embodiment of the power receiving structure 20, the adapter 23 optionally includes a universal connector 23a connected to the power receiving electrode 21 and at least two adapters 23c. The at least two adapters 23c are of different models and are selectively connected to the universal connector 23a. The adapters 23c are used to connect to the charging interface 246 of a laptop computer. Generally speaking, laptops from different manufacturers or different models may have different sizes and models of their charging interfaces 246. In this embodiment, by providing users with multiple models of adapters 23c to adapt to different models of charging interfaces 246, the power receiving piece 220 can be used with different laptops, thereby improving the versatility and flexibility of the power receiving piece 220 and enhancing the user experience. Specifically, in this embodiment, the adapters 23c may include Type-C connectors, round connectors, and square connectors to adapt to Type-C interfaces, round interfaces, and square interfaces, respectively. Of course, in other embodiments, a universal connector may not be provided, and the adapter may be a fixed model of charging connector, such as a Type-C connector.

[0111] Please refer to Figures 10 to 14 In another embodiment of the power receiving structure 20, the power receiving electrode 21 is disposed on the bottom surface of the power receiving base body 231. This facilitates the alignment of the power receiving electrode 21 on the laptop with the power supply electrode 11 on the desktop 142, thereby facilitating the laptop's charging operation. The weight of the laptop and the power receiving base 230 ensures that the power receiving electrode 21 remains effectively and continuously pressed against the power supply electrode 11, preventing accidental detachment and potential charging malfunctions. Alternatively, in other embodiments, the power receiving electrode can be disposed on the side wall of the power receiving base body 231 of the power receiving device, cooperating with a power supply electrode disposed on the wall. For example, a power supply plate is mounted on a wall and positioned close to the ground. A robot vacuum cleaner is equipped with a power receiving base and the power receiving electrode is exposed on its side. When the robot vacuum cleaner approaches the wall, the power receiving electrode comes into contact with the power supply electrode on the wall, forming a circuit loop and thus achieving the charging function.

[0112] In another embodiment of the power receiving structure 20, the power receiving base 230 further includes a power receiving connection circuit 22 connected between the power receiving electrode 21 and the adapter 23. The power receiving connection circuit 22 is located on the side of the power receiving base body 231 away from the power receiving electrode 21. Specifically, the power receiving base body 231 has a mounting through hole corresponding to the power receiving electrode 21. The power receiving electrode 21 is connected to the power receiving connection circuit 22 through a connecting post 215, which is located in the mounting through hole. This avoids the problem of the power receiving connection circuit 22 being exposed to the outside for a long time and thus prevents damage, protecting the power receiving connection circuit 22 and improving the service life of the power receiving base 230. Of course, in some embodiments, the power receiving connection circuit can also be located on the bottom surface of the base body, and the power supply base also includes a protective film or gasket covering the power receiving connection circuit. In other embodiments, the power receiving electrode is located on the edge of the base body, one end of the power receiving connection circuit is connected to the power receiving electrode, and the other end extends over the side of the base body to the side of the base body away from the power receiving electrode.

[0113] In another embodiment of the power receiving structure 20, optionally, a connecting post 215 is provided on the power receiving electrode 21, and the power receiving connection circuit 22 has a mounting hole corresponding to the connecting post 215. The connecting post 215 passes through the mounting through hole and is inserted into the mounting hole. Specifically, after the connecting post 215 of the power receiving electrode 21 passes through the mounting through hole, it is inserted and locked into the mounting hole on the power receiving connection circuit 22, thereby completing the installation of the power receiving electrode 21 and the power receiving connection circuit 22. This facilitates the installation between the power receiving electrode 21 and the power receiving connection circuit 22. Of course, in other embodiments, the connecting post can also be provided on the power receiving connection circuit, with one end of the connecting post passing through the mounting through hole and being bonded to the power receiving electrode with conductive adhesive.

[0114] In another embodiment of the power receiving structure 20, optionally, the power receiving base body 231 is provided with a mounting groove 231b corresponding to the power receiving connection circuit 22, and the power receiving connection circuit 22 is housed in the mounting groove 231b, with a mounting through hole located at the bottom of the mounting groove 231b. Thus, by housing the power receiving connection circuit 22 within the mounting groove 231b, the problem of wear and tear after long-term use can be avoided by the power receiving connection circuit 22 being sandwiched between the laptop's bottom cover 242 and the power receiving base body 231 of the power receiving base 230, thereby extending the service life of the power receiving base 230. It is worth mentioning that when the bottom cover 242 is made of a conductive material, and the power receiving connection circuit 22 is configured as a conductive foil or similar exposed conductive structure, housing the power receiving connection circuit 22 within the mounting groove 231b can also prevent electrical connection between the power receiving connection circuit 22 and the bottom cover 242, thus preventing short circuits between different circuit loops via the bottom cover 242. Of course, in other embodiments, the mounting groove may not be provided.

[0115] In another embodiment of the power receiving structure 20, optionally, the power receiving electrode 21 is fixed to the bottom surface of the power receiving base body 231 by adhesive, and the power receiving connection circuit 22 is fixed in the mounting groove 231b of the power receiving base body 231 by adhesive. This facilitates the installation of the power receiving electrode 21 and the power receiving connection circuit 22 by workers, and also ensures the connection relationship between the power receiving electrode 21 and the power receiving connection circuit 22, thereby improving the working stability of the power receiving base 230. Of course, in other embodiments, the connecting posts of the power receiving electrode can also be welded or adhesively fixed to the mounting holes of the power receiving connection circuit.

[0116] In another embodiment of the power receiving structure 20, the power receiving base body 231 may optionally be made of an insulating material. Specifically, the insulating material can be rubber, plastic, glass, ceramic, mica, or asbestos, etc. This prevents short circuits caused by electrical connections between different power receiving circuits 22 via the conductive power receiving base body 231, thus ensuring the normal power receiving operation of the power receiving base 230. Of course, in some embodiments, an insulating structure may be sandwiched between the power receiving electrode and the base body. Specifically, the insulating structure can be insulating adhesive, insulating varnish, insulating silicone grease, insulating film, plastic sheet, or ceramic sheet, etc. In other embodiments, the base body is made of an insulating material, and an insulating structure is sandwiched between the power receiving electrode and the base body.

[0117] In another embodiment of the power receiving structure 20, optionally, the power receiving socket body 231 is provided with a receiving groove 231c for embedding into the bottom of a laptop computer. Specifically, the power receiving socket body 231 includes a body segment 232 and a clamping flange 233 provided on the side edge of the body segment 232. The clamping flange 233 has a clamping protrusion 234 protruding towards the center of the body segment 232, which is used to abut against the laptop computer. The body segment 232, the clamping flange 233, and the clamping protrusion 234 together define the receiving groove 231c. In this way, the power receiving socket 230 can be stably nested in the bottom of the laptop computer, and quick installation and removal can be achieved. This allows users to selectively install the power receiving socket 230 on the laptop computer as needed, and also makes it convenient for users to remove the power receiving socket 230 for daily cleaning of the power receiving socket 230 and the laptop computer. Of course, in some embodiments, the socket body can also be attached to the bottom cover of the casing by a vacuum suction cup.

[0118] In another embodiment of the power receiving structure 20, the power receiving base body 231 further has at least four support legs 235 protruding towards the power receiving electrode 21. These four support legs 235 are arranged in a rectangular pattern with their corners spaced apart. Two power receiving electrodes 21 are respectively disposed on two support legs 235. The side of the support leg 235 away from the power receiving electrode 21 is provided with a recess 231a. Specifically, in this embodiment, both the protruding surface of the support leg 235 and the recess 231a are arc-shaped, for example, spherical or nearly spherical. The recess 231a of the support leg 235 serves to avoid the protruding feet 243 of the laptop computer, thereby facilitating the installation of the power receiving base 230 with the laptop computer and allowing the bottom cover 242 of the laptop computer to fit well against the inner side of the power receiving base body 231. Of course, in other embodiments, the support legs may not be provided.

[0119] In another embodiment of the power receiving structure 20, optionally, the adapter 23 is located outside the power receiving base body 231. The side edge of the power receiving base body 231 has a clearance opening 231d corresponding to the power receiving connection circuit 22. One end of the power receiving connection circuit 22 passes through the clearance opening 231d and connects to the adapter 23. This avoids the adapter 23 being sandwiched between the power receiving base body 231 and the power receiving device 240, preventing wear and operational difficulties. Of course, in other embodiments, the clearance opening may not be provided; instead, the side edge of the base body protrudes outwards and forms a recessed groove. One end of the power receiving connection circuit receives the recessed groove and folds over the side edge of the base body to connect with the adapter.

[0120] In another embodiment of the power receiving structure 20, the adapter 23 optionally includes an adapter 23c and a connector 23b connected together. The adapter 23c is used to connect to the charging connection position 246, and the connector 23b is detachably connected to the power receiving connection circuit 22. Specifically, the power receiving connection circuit 22 and the connector 23b are detachably connected via a first connector 237, which is located on the side of the power receiving connection circuit 22 away from the power receiving base body 231. The first connector 237 can be a board-to-board connector, a board-to-wire connector, etc., depending on the specific structure of the power receiving connection circuit 22 and the connector 23b. The structure of the first connector 237 can be a bayonet connection, a locking connection, a push-pull connection, a direct plug connection, etc. In this way, it is convenient to install the adapter 23 and the power receiving connection circuit 22, and it is also convenient for users to disassemble and install the adapter 23 for daily cleaning, maintenance and replacement. It is easily understood that since the adapter 23 is constantly exposed to the outside of the power receiving base 230, dust and dirt easily accumulate, thus requiring daily cleaning. Removing the adapter 23 separately allows the user to easily clean it. Of course, in some embodiments, the adapter may include a connector that is directly mounted at the end of the power receiving connection circuit. In other embodiments, the adapter includes a connected connector and at least two conductive wires, the ends of which are exposed. The power receiving connection circuit is configured as conductive wires, and the conductive wires on the adapter can be intertwined with the conductive wires of the power receiving connection circuit to achieve a detachable connection.

[0121] In another embodiment of the power receiving structure 20, optionally, at least two adapters 23 are provided, and the at least two adapters 23 are of different models, and one of them is selectively connected to the power receiving connection circuit 22. Generally speaking, laptops manufactured by different companies or of different models may have different sizes and models of charging interfaces 246. In this embodiment, by providing users with multiple models of adapters 23c (adapter parts 23) to adapt to different models of charging interfaces 246, the power receiving socket 230 can be used with different laptops, thereby improving the versatility and flexibility of the power receiving socket 230, and thus enhancing the user experience. Secondly, since the adapter part 23 is detachably connected to the power receiving connection circuit 22, it is convenient for users to replace the required adapter part 23. Specifically, in this embodiment, the adapter 23c may include a Type-C connector, a round connector, and a square connector to adapt to Type-C interfaces, round interfaces, and square interfaces, respectively.

[0122] In another embodiment of the power receiving structure 20, the power receiving base 230 further includes a cover 236 connected to the power receiving base body 231 and used to at least cover the connector 23b. This protects the connector 23b, the first connector 237, and the power receiving connection circuit 22 exposed on the outside of the power receiving base body 231, and ensures the connection between these three components, preventing abnormal charging operation due to accidental disconnection of these components.

[0123] In another embodiment of the power receiving structure 20, optionally, the cover 236 also shields at least a portion of the adapter 23c. Specifically, in this embodiment, the cover 236 includes a first cover 236a and a second cover 236b, which are separately configured. The first cover 236a shields the connector 23b, and the second cover 236b shields the adapter 23c. Thus, the cover 236 also protects the adapter 23c, preventing the adapter 23c from being damaged by accidental bumps during use, and also providing partial dust and water protection. Secondly, since the first cover 236a and the second cover 236b are separately configured, users can install them according to their needs, thereby improving the flexibility of the power receiving socket 230. Of course, in other embodiments, the cover may also include a first cover segment and a second cover segment, which are formed as a single unit, with the first cover segment shielding the connector and the second cover segment shielding the adapter.

[0124] In another embodiment of the power receiving structure 20, optionally, the first cover 236a is detachably connected to the power receiving base body 231, and the second cover 236b is embedded in the adapter 23c. Specifically, in this embodiment, the first cover 236a has a latching protrusion, and the power receiving base body 231 has a corresponding latching groove, allowing the latching protrusion to be latched into the latching groove. Of course, in other embodiments, the cover can also be detachably connected to the base body by means of Velcro, screws, or other methods.

[0125] Please refer to Figures 15 to 20 In another embodiment of the power receiving structure 20, the power receiving electrode 21 is optionally disposed on the bottom surface of the bottom cover 242 of the laptop. This facilitates the alignment of the power receiving electrode 21 on the laptop with the power supply electrode 11 on the desktop 142, thereby facilitating charging operations. The weight of the laptop ensures that the power receiving electrode 21 remains effectively and continuously pressed against the power supply electrode 11, preventing accidental detachment and potential malfunctions in power supply / charging. Alternatively, in other embodiments, the power receiving electrode assembly can be disposed on the side wall of the device's housing to cooperate with power supply electrodes mounted on the wall. For example, a power supply plate is mounted on a wall and positioned close to the ground, while a robot vacuum cleaner has power receiving electrodes on its side wall. When the robot vacuum cleaner approaches the wall, the power receiving electrodes come into contact with the power supply electrodes on the wall, forming a circuit and thus enabling charging.

[0126] In another embodiment of the power receiving structure 20, optionally, the power receiving connection circuit 22 is located on the side of the bottom cover 242 away from the power receiving electrode 21. Specifically, the bottom cover 242 has a mounting through hole corresponding to the power receiving electrode 21, and the power receiving electrode 21 is connected to the power receiving connection circuit 22 through a connecting post 215, which is located in the mounting through hole. This avoids the problem of the power receiving connection circuit 22 being damaged due to long-term exposure, thus protecting the power receiving connection circuit 22 and improving the service life of the power receiving socket 230. Of course, in some embodiments, the power receiving connection circuit can also be located on the bottom surface of the bottom cover, and the power supply socket also includes a protective film or gasket covering the power receiving connection circuit. In other embodiments, the power receiving electrode is located on the edge of the bottom cover, one end of the power receiving connection circuit is connected to the power receiving electrode, and the other end extends beyond the side of the bottom cover to the side of the bottom cover away from the power receiving electrode.

[0127] In another embodiment of the power receiving structure 20, optionally, a connecting post 215 is disposed on the power receiving electrode 21, and the power receiving connection circuit 22 has a mounting hole corresponding to the connecting post 215. One end of the connecting post 215 passes through the mounting through hole and is inserted into the mounting hole. Specifically, after the connecting post 215 of the power receiving electrode 21 passes through the mounting through hole, it is inserted and engaged with the mounting hole on the power receiving connection circuit 22, thereby completing the installation of the power receiving electrode 21 and the power receiving connection circuit 22. This facilitates the installation between the power receiving electrode 21 and the power receiving connection circuit 22. Of course, in other embodiments, the connecting post can also be disposed on the power receiving connection circuit, with one end of the connecting post passing through the mounting through hole and being bonded to the power receiving electrode with conductive adhesive.

[0128] In another embodiment of the power receiving structure 20, optionally, the power receiving connection circuit 22 is bonded to the bottom cover 242, and the power receiving electrode 21 is bonded to the bottom cover 242. This facilitates the installation of the power receiving electrode 21 and the power receiving connection circuit 22 by workers, while also ensuring the connection between the power receiving electrode 21 and the power receiving connection circuit 22, thereby improving the operational stability of the laptop computer. Of course, in other embodiments, the connecting posts of the power receiving electrode can also be welded or bonded to the mounting holes of the power receiving connection circuit.

[0129] In another embodiment of the power receiving structure 20, a first insulating structure (not shown in the figures) is sandwiched between the power receiving electrode 21 and the bottom cover 242, and a second insulating structure is sandwiched between the power receiving connection circuit 22 and the bottom cover 242. The power receiving device also includes electronic components (including a main control circuit board, heat sink, fan, etc.) disposed within the housing, and a third insulating structure is sandwiched between the connection circuit and the electronic components. Specifically, the insulating structure can be insulating adhesive, insulating varnish, insulating silicone grease, insulating film 245, plastic sheet, or ceramic sheet, etc. In this embodiment, the power receiving electrode 21 is bonded to the bottom surface of the bottom cover 242 with insulating adhesive, and the power receiving connection circuit 22 is disposed on an insulating film 245. The side of the insulating film 245 facing away from the power receiving connection circuit 22 is provided with adhesive and fixed to the inside of the bottom cover 242. Alternatively, the insulating film can be pasted on the side of the electronic components facing the connection circuit, or insulating silicone grease can be applied. In this way, short circuits can be avoided due to electrical connections between different power-receiving connection circuits 22 or between different power-receiving electrodes 21 via the conductive bottom cover 242 or electronic components, thus ensuring the normal power-receiving operation of the laptop. Of course, in some embodiments, the bottom cover can be made of an insulating material. In this case, since the bottom cover is non-conductive, it is not necessary to provide an insulating structure between the power-receiving electrodes and the bottom cover, or between the power-receiving connection circuit and the bottom cover. In other embodiments, the bottom cover is made of an insulating material, and a first insulating structure is sandwiched between the power-receiving electrodes and the bottom cover, while a second insulating structure is sandwiched between the connection circuit and the bottom cover.

[0130] In another embodiment of the power receiving structure 20, optionally, the main control circuit board 244 is provided with a second connector 247, one end of which is electrically connected to the power receiving connection circuit 22. Specifically, the second connector 247 is configured as a spring-loaded pin, which facilitates the installation of the main control circuit board 244 and the power receiving connection circuit 22, and effectively ensures the connection relationship between the main control circuit board 244 and the power receiving connection circuit 22, thereby improving the working stability of the laptop. Secondly, the spring-loaded pin has the advantages of simple structure, compact size, and good transmission performance. Of course, in other embodiments, the connector can also be configured as a board-to-board connector, a board-to-wire connector, etc., depending on the specific structure of the power receiving connection circuit and the connector head; the connector structure can adopt bayonet connection, locking connection, push-pull connection, direct plug connection, etc.

[0131] In another embodiment of the power receiving structure 20, the power receiving device 240 further includes a rechargeable battery (not shown in the figures), which is electrically connected to the main control circuit board 244. Thus, the electrical energy received by the power receiving electrode 21 is input to the rechargeable battery through the main control circuit board 244 and stored therein. When there is no external power source available, the laptop can operate using the electrical energy stored in the rechargeable battery, thereby improving the laptop's ease of use and flexibility.

[0132] In another embodiment of the power receiving structure 20, the power receiving device 240 further includes a charging connection position 246 electrically connected to the main control circuit board 244, which is used to connect to an external power source. Specifically, the charging connection position 246 can be a charging interface 246, a charging connector, a charging contact, etc. In this embodiment, the charging interface 246 is provided on the side wall of the laptop casing 241. Thus, providing the charging interface 246 as a backup, additional charging method allows users to make reasonable choices based on usage scenarios and needs. That is, users can choose to obtain power from an external power source through the charging interface 246 or through the power receiving electrode 21, thereby improving the adaptability of the power receiving device 240 to various usage scenarios. For example, when the laptop's usage environment does not have a table with a power supply electrode 11, the user can connect to an external power source through the charging interface 246. Of course, in other embodiments, the charging connection position may not be provided.

[0133] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
