Along with the development of science and technology level, smart machine receives people's favor more and more, for example notebook computer and sweeper, the former possesses good portability, and the diversified advantage of application scene, and can satisfy the demand that the user freely worked official business, the amusement, and the latter is through automatic sweeping, clean ground, and can alleviate user's sanitary clean burden. However, these intelligent devices all have the problems of high work power consumption, frequent charging requirements, and inconvenient charging operation. For example, in the charging operation of the existing notebook computer, a user is required to insert a power plug of a power adapter into a power socket first during each charging, then identify the position of a charging interface on the notebook computer, and visually align the charging plug of the power adapter with the charging interface, so that the charging plug can be accurately inserted into the charging interface. It can be seen that the charging operation of the powered device (notebook computer) is not only complicated in steps, but also does not support blind operation of the user.

In view of this, the present invention provides a power receiving sheet, which is used between a power receiving device and a power supply structure, wherein the power receiving device is provided with a charging connection location, the power supply structure is provided with a power supply electrode group exposed on a supporting surface, the power supply electrode group includes at least two power supply electrodes, and the power supply electrode group is electrically connected to an external power supply such as a power socket. The power receiving equipment can be a mobile intelligent terminal such as a notebook computer, a tablet computer and a mobile phone, and also can be intelligent equipment such as a sweeper and an intelligent sound box, and the charging connection position can be a charging interface, a charging connector, a charging contact and the like. Referring to fig. 1 to 4, in an embodiment of the present invention, the power receiving sheet 10 includes:

the adaptor 132 is electrically connected to the power receiving electrode group and is used to be mounted and electrically connected to the charging connection site 71.

In the technical solution of the present invention, the power receiving sheet 10 is installed on the power receiving device 70, for example, by using adhesive, hook and loop fastener, drawing pin, shooting pin, or screw, and the power receiving electrode 12 is exposed, so that the user can conveniently contact and electrically connect the power supply electrode 912 on the supporting surface 81 with the power receiving electrode; then, the adaptor 132 is mounted on the charging connection site 71, that is, the power receiving sheet 10 and the power receiving device 70 are mounted. Specifically, two power supply electrodes 912 are disposed on the supporting surface 81 and respectively serve as a positive terminal and a ground terminal (a negative terminal), and two power receiving electrodes 12 are correspondingly disposed on the power receiving device 70 and respectively electrically connected to the two power supply electrodes 912 to form a circuit loop. The two power receiving electrodes 12 may be disposed on one power receiving base film 11, and a user may directly install one power receiving sheet 10, or only one power receiving electrode 12 is disposed on one power receiving base film 11, and the user needs to install two power receiving sheets 10 to obtain the two power receiving electrodes 12. In this way, when charging is required, the power receiving device 70 is only required to be placed on the supporting surface 81 so that the power feeding electrode 912 is in contact with the power receiving electrode 12, and at this time, the electric energy of the external power source at least passes through the power feeding electrode 912, the power receiving electrode 12, the adapter 132, and the charging connection position in sequence to supply power to the power receiving device 70. Compared with the prior art, the charging operation process is not only simple and convenient to operate, but also supports the blind operation of the user, so that the charging operation convenience of the power receiving equipment 70 is improved. For example, for a notebook computer, the user does not need to search for the charging interface 71 on the notebook computer and align and insert the charging plug into the charging interface 71 at least every time, so as to improve the charging experience of the user.

It should be noted that, the utility model discloses among the technical scheme, receive the piece and indicate to receive the whole slice setting that is of electrical structure, also promptly, thickness dimension far is less than length/width size. The power receiving sheet may not be provided with a power receiving base film, but the power receiving electrode may be directly mounted or placed on the supporting surface.

It can be understood that, in this embodiment, the receiving electrode on the receiving sheet is in contact with the power supply electrode to realize a charging form of wired charging of the receiving device, and a larger charging power can be supported, so as to improve the charging efficiency in the charging process, and meet the use requirement of the receiving device with higher working power, such as a notebook computer. That is, the wireless charging experience can be obtained with the efficiency of wired charging.

In particular, the support surface 81 may be a plane suspended in the air, such as a table top of the table 80, or a floor or wall surface, such as a tiled floor. In the scenario where the power supply structure 90 is disposed on the ground, it is suitable for the powered device 70 working on the ground, such as a smart device like a sweeper. Specifically, by installing the power receiving sheet 10 on the bottom surface of the sweeper, the power feeding electrode 912 can be automatically connected after the sweeper moves to the area of the power feeding electrode 912 on the ground, and electric energy can be obtained from the power feeding electrode 912, so that the charging operation of the sweeper is significantly simplified, and the connection relationship between the power feeding electrode 912 and the power receiving electrode 12 can be ensured by the self weight of the sweeper, so that the charging operation can be continuously and normally performed. It should be noted that the connection relationship between the power feeding electrode and the power receiving electrode does not refer to the installation relationship between the power feeding electrode and the power receiving electrode, but includes the abutting relationship of the power receiving electrode placed on the power feeding electrode.

When the supporting surface 81 is a table top of a table, that is, the supporting member is a table, the power receiving sheet 10 is suitable for smart devices such as notebook computers, tablet computers, and mobile phones. The table may be an office table, a conference table, a library desk, a dining table, or the like in a public scene, a study desk, a dining table, a dressing table, or the like in a home scene, or a storable table in a vehicle, for example, a table panel on the back of a high-speed rail seat, a table panel on the back of a front seat of an automobile, or the like. Of course, the table may be a small bed desk that is foldable, portable, or the like, in addition to the bulky, difficult or immovable structure. As will be described below by taking a desk and a notebook computer as an example, the power receiving sheet 10 is mounted on the bottom cover 72 of the notebook computer. Since the notebook computer needs to be charged through the power adapter 92, the power adapter 92 may be mounted on a desk in advance, and the power adapter 92 may be electrically connected to an external power source. Since the power adapter 92 is connected to the power feeding electrode 912, the power obtained from the external power source at least passes through the power adapter 92, the power feeding electrode 912, the power receiving electrode 12, the adapter 132, and the notebook charging interface 71 in sequence to supply power to the notebook computer. Thus, it is allowed that only the power supply electrode 912 is exposed on the desktop, and other components such as the electrical connection portion 916 and the power adapter 92 are disposed outside the desktop, for example, at the bottom of the desktop or at the side of the desktop 80, so as to avoid the problem of messy and untidy desktop caused by the placement of the power adapter 92 and the wires on the desktop. That is, the problem of flying lines on the desktop can be avoided, so that the desktop is tidier.

It is worth mentioning that, under the situation that the notebook computer is used in a public scene, for example, the desk is a conference desk in a conference room or a desk in a library, because the desk is pre-configured with the power adapter 92, the user can charge the notebook computer without carrying the power adapter 92, the trouble that the user carries the power adapter 92 which is bulky and heavy is avoided, thereby facilitating the mobile office or entertainment of the user, and further improving the user experience. Similarly, under the situation that the notebook computer is used in a home scene, convenience can be provided when the user moves and uses the notebook computer, for example, if the power supply electrode 912 and the power adapter 92 are arranged on a desk of a study room, a dining table of a restaurant and a dressing table of a bedroom, the user can be supported to move to work at the positions and switch the positions freely, and the power adapter 92 is not required to be carried in the whole process.

It should be further noted that the power supply structure 90 is disposed on the desk 80 in various forms, for example, referring to fig. 4, in an embodiment of the desk 80, at least two power supply electrodes 912 are first disposed on a power supply base film 911 to form a power supply film 91, and then the power supply film 91 is fixed on the desktop of the desk 80 by using an adhesive, a screw, or a nail; the power adapter 92 is disposed on the side surface of the table 80 or the bottom surface of the table 80, and the power adapter 92 and the feeding electrode 912 are electrically connected by an electrical connection portion 916, where the electrical connection portion 916 may be at least one of a conductive wire, a conductive sheet, a flexible circuit board, and the like, and the electrical connection portion 916 is also disposed on the feeding base film 911. In another embodiment of the desk 80, at least two power supply electrodes 912 are first disposed on a power supply seat, the power supply seat can be placed or embedded on the desk 80, the connection circuit 131 is disposed in the power supply seat or on the bottom surface of the power supply seat, and the power adapter 92 is disposed on the side surface or the bottom surface of the desk 80. In another embodiment of the desk 80, at least two power supply electrodes 912 are directly embedded in the desk 80, the connection circuit 131 is disposed in the desk 80 or on the bottom surface of the desk 80, and the power adapter 92 is disposed on the bottom surface of the desk 80. In the above solution, the power supply electrode 912 may be configured as at least one of a conductive foil, a conductive sheet, a conductive film, a flexible circuit board, a metalized plastic body, and a pogo pin. Specifically, the conductive foil may be a copper foil, an aluminum foil, or the like; 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 and the like; the metallized plastic body can be prepared by a process of surface metallization of plastic or integral metallization of plastic. Thus, the area of the desk plate 80 covered by the power supply electrode 912 can be increased by the power supply electrode 912 which is unfolded, so that the displacement of the notebook computer on the desk plate 80 within a certain range is allowed, that is, the power receiving electrode 12 on the notebook computer can move in the area covered by the power supply electrode 912 to keep the abutting connection and the electrical connection, thereby ensuring the normal power supply work of the notebook computer, and further improving the use flexibility and convenience of the charging operation.

In an embodiment, optionally, the power receiving pad is mounted on a bottom surface of the power receiving device, and the power receiving electrode group is exposed on the bottom surface of the power receiving device. Therefore, the power receiving electrode on the notebook computer can be conveniently aligned with the power supply electrode on the desktop, so that the notebook computer can be conveniently charged, and the power receiving electrode continuously and effectively abuts against the power supply electrode by utilizing the weight of the notebook computer and the power receiving seat, so that the problem of abnormal charging operation caused by accidental disengagement of the power receiving electrode and the power supply electrode is avoided. Of course, in other embodiments, the power receiving electrode group may also be disposed on a side wall of the power receiving device to cooperate with a power supply electrode disposed on a wall surface. For example, the power supply film is installed on the wall surface and is arranged close to the ground, the power receiving sheet is pasted on the side wall of the sweeper, the power receiving electrode is exposed on the side surface, and when the sweeper approaches to the wall surface, the power receiving electrode can be abutted to the power supply electrode on the wall surface to form a circuit loop, so that the charging function is realized.

Specifically, the power feeding electrode 912 of the table 80 is provided with a first power feeding electrode 913 and a second power feeding electrode 914 corresponding thereto, and serves as a positive terminal and a ground terminal, respectively, so as to be electrically connected to the first power receiving electrode 121 and the second power receiving electrode 122 to form a circuit loop. The power adapter 92 may obtain the charging parameters required by the notebook computer during the charging process by using carrier communication, load identification circuit or wireless communication. For example, a load identification circuit module is disposed between the power receiving electrode 12 of the power receiving sheet 10 and the power adapter 92 to negotiate parameters such as charging voltage and current of the notebook computer. For another example, a first wireless module is disposed on the notebook computer, a second wireless module is disposed on the power receiving sheet 10 or the power adapter 92, and the first wireless module and the second wireless module can achieve wireless communication connection so as to transmit the charging parameters of the notebook computer to the power adapter 92; specifically, the Wireless module may adopt any form of a Wi-Fi (Wireless Fidelity ) module, a bluetooth module, a 5G (5 th generation mobile communication) module, a 4G (4 th generation mobile communication) module, and the like. So, establish on same membrane body through receiving first powered electrode 121 and second powered electrode 122, can enough make things convenient for production, storage management, transportation and sale to receive electric piece 10 to reduce the manufacturing cost of receiving electric piece 10, again can convenience of customers deposit and paste this and receive electric piece 10 product, thereby improve user experience. Of course, in other embodiments, the power receiving base film may include at least two film bodies separately disposed, and only one power receiving electrode is disposed on one film body, and then a user may purchase two independent film bodies and adjust the distance and the relative position relationship between the two power receiving electrodes by adjusting the pasting positions of the two film bodies on the case bottom cover of the notebook computer.

In an embodiment, the power receiving electrode group further includes a third power receiving electrode 123, the third power receiving electrode 123 is spaced apart from the first power receiving electrode 121 and the second power receiving electrode 122, the first power receiving electrode 121, the second power receiving electrode 122 and the third power receiving electrode 123 are disposed on the film body, and the third power receiving electrode 123 serves as a signal terminal.

It can be understood that the power supply electrode 912 on the desk 80 further includes a third power supply electrode 915, and is disposed corresponding to the third power receiving electrode 123, so that the power adapter 92 can directly obtain the charging parameters of the notebook computer through the power supply film 91 and the power receiving sheet 10 by using the third power receiving electrode 123 as a signal terminal. Secondly, establish on same membrane body through receiving first electrode 121, second receiving electrode 122 and third receiving electrode 123, can enough make things convenient for production, storage management, transportation and sale receiving piece 10 to reduce receiving piece 10's manufacturing cost, again can convenience of customers deposit and paste and use this receiving piece 10 product, thereby improve user experience. Of course, in some embodiments, the power receiving base film may include at least two film bodies separately disposed, one film body is provided with the first power receiving electrode and the second power receiving electrode, and the other film body is provided with the third power receiving electrode; or a first power receiving electrode and a third power receiving electrode are arranged on one film body, and a second power receiving electrode is arranged on the other film body; or each power receiving electrode is correspondingly arranged on an independent membrane body. In other embodiments, the first power receiving electrode, the second power receiving electrode and the third power receiving electrode may be arranged at intervals along the same direction.

In an embodiment, optionally, the power receiving electrode group further includes a fourth power receiving electrode 124, and the four power receiving electrodes 12 (including the first power receiving electrode 121, the second power receiving electrode 122, the third power receiving electrode 123 and the fourth power receiving electrode 124) are distributed at intervals in a rectangular four-corner direction. Specifically, in the present embodiment, the first power receiving electrode 121 and the second power receiving electrode 122 are located on the left side of the notebook computer, the third power receiving electrode 123 and the fourth power receiving electrode 124 are located on the right side of the notebook computer, and the third power receiving electrode 123 and the fourth power receiving electrode 124 are electrically connected and jointly used as a signal terminal.

It can be understood that the third power feeding electrode 915912 on the desk 80 is disposed corresponding to the third power receiving electrode 123 and the fourth power receiving electrode 124 at the same time, so that the contact area of the signal terminal can be increased, the signal terminal of the notebook computer is allowed to move on the desk 80 within a certain range, and the flexibility of the charging operation is further improved. Of course, in some embodiments, the number of the power receiving electrodes may also be set to be 5, or 6, 8, etc., and the specific number is not limited. In other embodiments, the third power receiving electrode and the fourth power receiving electrode are electrically connected and commonly used as a positive terminal, and the first power receiving electrode and the second power receiving electrode are respectively used as a signal terminal and a ground terminal; or the third power receiving electrode and the fourth power receiving electrode are electrically connected and commonly used as a grounding terminal, and the first power receiving electrode and the second power receiving electrode are respectively used as a signal terminal and a positive terminal.

That is, compared with the wireless charging technology, the present embodiment can also enable the notebook computer to have a larger moving range on the desktop. Of course, in other embodiments, the power receiving electrode may also be configured as a pogo pin or the like.

In an embodiment, optionally, the power receiving electrode 12 and the power receiving base film 11 are integrally formed by hot press molding. Thus, the connection strength between the power receiving electrode 12 and the power receiving base film 11 can be ensured, the problem that the power receiving electrode 12 is accidentally separated from the power receiving base film 11 when the power receiving sheet 10 is in use is avoided, and the service life of the power receiving sheet 10 is prolonged.

In one embodiment, the power feeding electrode 912 is disposed in a planar shape, and the power receiving electrode 12 is disposed in a dot shape. The dot shape means that a contact area of the dot-shaped structure on the planar structure is much smaller than an area of the planar structure, that is, a relative magnitude relationship, and therefore, the dot shape is not particularly limited to only one small contact point. Therefore, compared with the point-shaped arrangement of the power supply electrode and the power receiving electrode, in the embodiment, the power supply electrode and the power receiving electrode can be abutted without being precisely positioned on the desktop, that is, the notebook computer can be randomly placed on the desktop to realize charging. In addition, the material consumption of the power supply electrode or the power receiving electrode can be reduced, and the manufacturing cost can be reduced. Of course, in other embodiments, both the power feeding electrode and the power receiving electrode may be arranged in a planar manner; alternatively, the power feeding electrode is disposed in a dot shape, and the power receiving electrode is disposed in a planar shape.
