However, these intelligent devices all have the problems of high working 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 is not only cumbersome in steps, but also does not support blind operation by the user.

In view of this, the present invention provides a power supply sheet for use between a supporting surface and a power receiving device, wherein the power receiving device has a power receiving electrode group, and the power receiving electrode group includes at least two power receiving electrodes. Referring to fig. 1 to 3, in an embodiment of the present invention, the power supply sheet 10 includes:

a power supply base film 110 having a first mounting surface (not shown in the drawings) and a second mounting surface 111 opposed to each other, the first mounting surface being configured to be mounted on the support surface 81;

the electrical connection portion 132 is electrically connected to the power supply electrode set and is used for electrically connecting to an external power source.

The utility model discloses among the technical scheme, through installing this power supply piece 10 on holding surface 81, for example through modes such as adhesive, magic subsides, drawing pin, penetrate the nail, or screw install to let the power supply electrode show up, convenience of customers will receive the power receiving electrode of electric installation and contact the electricity with it and be connected. Specifically, at least two power supply electrodes are respectively used as a positive terminal and a ground terminal (negative terminal), and two power receiving electrodes of the power receiving device are correspondingly arranged so as to be respectively electrically connected with the two power supply electrodes and form a circuit loop. The electric energy of the external power supply at least sequentially passes through the electric connection part, the power supply electrode and the power receiving electrode so as to supply power to the power receiving device. So, when needs charge, only need place the receiving device on holding surface 81 to make power supply electrode and receiving electrode contact can, this operation of charging process compares in prior art, and is not only easy and simple to handle, supports user blind operation moreover, thereby improves the operation convenience that charges of receiving device. For example, for a notebook computer, a user does not need to concentrate on the operations of finding a charging interface on the notebook computer and aligning and inserting a charging plug into the charging interface at least every time, so that the charging experience of the user is improved.

It should be noted that, in the technical solution of the present invention, the power supply sheet indicates that the power supply structure is integrally arranged in a sheet shape, that is, the thickness dimension is far smaller than the length/width dimension. The power feeding sheet may not be provided with the power feeding base film, but the power feeding electrode may be directly mounted or placed on the supporting surface.

In particular, the support surface can be either a plane suspended in the air, such as a table top of a table, or a floor, for example a tile floor, on which tiles are laid. The power supply sheet is installed on the ground, the power receiving electrode is arranged on the bottom surface of mobile intelligent equipment (power receiving device) such as a sweeping robot, the power supply electrode can be automatically connected after the mobile intelligent equipment moves to the power supply sheet, electric energy is obtained from the power supply electrode, accordingly, the charging operation of the mobile intelligent equipment is remarkably simplified, the connection relation between the power supply electrode and the power receiving electrode can be guaranteed by means of the self weight of the mobile intelligent equipment, and therefore the charging operation can be continuously and normally carried out. 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 is a table top of a table, that is, the supporting member is a table, the power supply sheet 10 is suitable for portable 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, since the notebook computer needs to be charged through the power adapter 140, the power adapter 140 may be mounted on the desk in advance, and the power adapter 140 may be electrically connected to an external power source such as a power outlet. The power adapter is electrically connected to the power feeding electrode 120 through the electrical connection portion 132, so that electric energy obtained from an external power source at least passes through the power adapter 140, the electrical connection portion 132, the power feeding electrode 120 and the power receiving electrode 922 in sequence to supply power to the notebook computer. In this way, it is allowed that only the power supply electrode 120 is exposed on the desktop, and other components such as the electrical connection portion 132 and the power adapter 140 are placed outside the desktop, for example, on the bottom of the desktop or on the side of the desktop 80, so as to avoid the problem of messy and untidy desktop caused by placing the power adapter 140 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 power adapter 140 is pre-configured on the desk, the user can charge the notebook computer without carrying the power adapter 140, the trouble that the user carries the power adapter 140 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 sheet 10 and the power adapter 140 are arranged on the desk of a study room, the dining table of a restaurant and the 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 140 does not need to be carried in the whole process.

The electrical connection portion 132 may be a conductive wire, a connector, a terminal, or the like, as long as connection with the power adapter 140 is achieved.

It should be further noted that, the power receiving device 90 may include a power receiving equipment 91 and a power receiving electrode structure externally disposed on the power receiving equipment 91, or the power receiving device 90 may include the power receiving equipment 91, and the power receiving electrode 922 is disposed on the power receiving equipment 91. Specifically, the powered device 91 may be a mobile intelligent device such as a notebook computer, a tablet computer, a mobile phone, and the like, taking the notebook computer as an example for description, please refer to fig. 3, in an embodiment of the powered device 90, the powered electrode structure is configured as a powered film, the powered film includes a powered base film 921, a powered electrode 922 disposed on the powered base film 921, and an adapter 923 electrically connected to the powered electrode 922, the adapter 923 is configured to be mounted and electrically connected to a charging interface of the notebook computer, and the powered film is adhered to a bottom surface of the notebook computer and exposes the powered electrode 922 downward. Thus, the electric energy at least sequentially passes through the power adapter 140, the electrical connection portion 132, the power supply electrode 120, the power receiving electrode 922, the adapter 923 and the charging interface to supply power to the notebook computer. Certainly, receive the electric electrode structure and can also configure into and receive the electric collet, receive the electric collet and include the collet body, locate the receiving electrode of collet body and with the adapter that is connected by the electric electrode electricity, the adapter is used for the interface installation and the electricity that charge with notebook computer, and the bottom surface at notebook computer is nested to the collet body to let the receiving electrode show out down.

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

In an embodiment, the first mounting surface is at least partially provided with an adhesive (not shown in the drawings), and the power supply sheet 10 further includes a release film (not shown in the drawings) covering at least a region of the first mounting surface where the adhesive is located.

Specifically, the first power feeding electrode 121 and the second power feeding electrode 122 correspond to a positive terminal and a ground terminal (negative terminal), and the power receiving electrode group of the power receiving device 90 is provided with a first power receiving electrode and a second power receiving electrode as the positive terminal and the ground terminal (negative terminal), respectively, so as to be electrically connected to the first power feeding electrode 121 and the second power feeding electrode 122 to form a circuit loop. The power adapter 140 may obtain power supply parameters required in the power supply process by using carrier communication, a load identification circuit, or wireless communication. For example, a load identification circuit module is provided between the power supply electrode 120 and the electrical connection portion 132 of the power supply sheet 10 or on the power adapter 140 to negotiate parameters of charging voltage, current, etc. of the power-supplied device 90. For another example, a first wireless module is disposed on the power receiving device 90, a second wireless module is disposed on the power supply sheet 10 or the power adapter 140, and the first wireless module and the second wireless module can implement wireless communication connection so as to transmit the charging parameter of the power receiving device 90 to the power adapter 140; 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 with first power supply electrode 121 and second power supply electrode 122, can enough make things convenient for production, storage management, transportation and sale power supply piece 10 to reduce the manufacturing cost of power supply piece 10, again can convenience of customers deposit and paste and use this power supply piece 10 product, thereby improve user experience. Of course, in other embodiments, the base film 110 may also include at least two film bodies separately disposed, and only one power supply electrode is disposed on one film body, and then a user may purchase two independent film bodies, and may adjust the distance and the relative position relationship between the two power supply electrodes by adjusting the pasting positions of the two film bodies on the table.

In an embodiment, optionally, the power supply electrode group further includes a third power supply electrode 123, the third power supply electrode 123 is distributed at an interval with the first power supply electrode 121 and the second power supply electrode 122, the first power supply electrode 121, the second power supply electrode 122 and the third power supply electrode 123 are disposed on the membrane body, the first power supply electrode 121 serves as a positive terminal, the second power supply electrode 122 serves as a ground terminal, and the third power supply electrode 123 serves as a signal terminal. Specifically, the first feeding electrode 121 and the second feeding electrode 122 are spaced apart from each other along a first direction, the second feeding electrode 122 and the third feeding electrode 123 are spaced apart from each other along a second direction, and the first direction intersects the second direction. It can be understood that the power receiving electrode group of the power receiving device 90 further includes a third power receiving electrode, and is disposed corresponding to the third power supplying electrode 123, so that the power adapter 140 can directly obtain the charging parameter of the power receiving device 90 via the power supplying sheet 10 by using the third power supplying electrode 123 as a signal terminal. Secondly, establish first power supply electrode 121, second power supply electrode 122 and third power supply electrode 123 on same membrane body, can enough make things convenient for production, storage management, transportation and sale power supply piece 10 to reduce the manufacturing cost of power supply piece 10, again can convenience of customers deposit and paste and use this power supply piece 10 product, thereby improve user experience. Of course, in some embodiments, the power supply base film may include at least two film bodies separately disposed, one film body is provided with the first power supply electrode and the second power supply electrode, and the other film body is provided with the third power supply electrode; or a first power supply electrode and a third power supply electrode are arranged on one film body, and a second power supply electrode is arranged on the other film body; or each power supply electrode is correspondingly arranged on an independent membrane body. In other embodiments, the first feeding electrode, the second feeding electrode and the third feeding electrode may be arranged at intervals along the same direction.

In one embodiment, the power supply electrodes (including the first power supply electrode 121, the second power supply electrode 122, and the third power supply electrode 123) are optionally configured as at least one of a conductive foil, a conductive sheet, a flexible circuit board, a metalized plastic body, and a conductive film. 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 table 80 covered by the power feeding electrode 120 can be increased by the power feeding electrode which is unfolded, so that the power receiving device 90 is allowed to displace within a certain range on the table 80, that is, the power receiving electrode 922 of the power receiving device 90 can move in the area covered by the power feeding electrode 120 to keep the abutting electrical connection relationship, thereby ensuring the normal power feeding operation of the power receiving device 90, and further improving the use flexibility and convenience of the power feeding sheet 10. 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 supply electrode may also be configured as a pogo pin or the like.

In an embodiment, optionally, the power supply electrode 120 is integrally formed with the power supply base film 110 by hot press molding. Thus, the connection strength between the power supply electrode 120 and the power supply base film 110 can be ensured, the problem that the power supply electrode 120 is accidentally separated from the power supply base film 110 when the power supply sheet 10 is in use is avoided, and the service life of the power supply sheet 10 is further prolonged. It is worth mentioning that the hot press molding process has the advantage of high yield due to mature technology. Of course, in other embodiments, the power supply electrode may be adhesively fixed to the power supply base film.

In an embodiment, optionally, the third feeding electrode 123 corresponds to the first feeding electrode 121 and the second feeding electrode 122 respectively at two opposite sides in the length direction thereof. Thus, the area of the table board 80 covered by the three power supply electrodes can be wider, which is beneficial for the power supply sheet 10 to adapt to the power receiving devices 90 with different sizes and models, thereby improving the universality of the power supply sheet 10. It is understood that the positions and sizes of the power receiving electrodes 922 of the power receiving devices 90 with different sizes may be different, for example, the sizes of the notebook computers are different, and the distances between two adjacent power receiving electrodes on the bottom covers of the notebook computers are different. Since the three power supply electrodes on the power supply sheet 10 are mutually and horizontally spread at intervals, the power receiving electrodes with different intervals can be effectively contacted and electrically connected after being placed on the power supply electrodes, so that the use requirements of notebook computers with different sizes are met. Secondly, can also allow the electrified setting to take place small amplitude and remove on table 80, also can not influence the normal work of power supply process, and then promote user experience.

In order to further improve the versatility of the power feeding sheet 10 and facilitate small movements of the power receiving device 91 on the table 80, in an embodiment, optionally, in the width direction of the supporting surface 81, the length dimensions of the first power feeding electrode 121 and the second power feeding electrode 122 are both smaller than the length dimension of the third power feeding electrode 123. Therefore, the notebook computer can be supported to have a larger moving range in the width direction of the desktop. Of course, in the embodiment in which the first power supply electrode, the second power supply electrode, and the third power supply electrode are sequentially arranged at intervals along the length direction of the tabletop, the length dimensions of the first power supply electrode, the second power supply electrode, and the third power supply electrode may also be approximately uniformly arranged in the width direction of the tabletop.

In one embodiment, the power feeding electrode 120 is disposed in a planar shape, and the power receiving electrode 922 is disposed in a dot shape. The dot shape means that the contact area of the dot-shaped structure on the planar structure is much smaller than the area of the planar structure, that is, the dot shape is relative to the planar structure, and therefore, the dot shape is not limited to just one small contact. Thus, compared with the point-like 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 the need of precisely positioning the notebook computer on the desktop, that is, the notebook computer can be freely 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.

Referring to fig. 1 and 2, in an embodiment, the power supply sheet 10 further includes a connection circuit 131 connected between the power supply electrode 120 and the electrical connection portion 132, and the connection circuit 131 is disposed on the second mounting surface 111 of the power supply base film 110. Specifically, the connection circuit 131 may be configured as a conductive wire, a conductive foil, a conductive sheet, a conductive film, a flexible circuit board, or the like. As described above, by providing the connection circuit 131 on the second mounting surface 111, the connection circuit 131 structure does not affect the close contact between the first mounting surface and the table 80, and the connection strength between the power feeding sheet 10 and the table 80 is improved. Next, it is understood that if the connection circuit 131 is provided on the first mounting surface, the feeding base film 110 needs to be opened to allow the feeding electrodes 120 on the second mounting surface 111 to be connected to the connection circuit 131 on the first mounting surface. In this embodiment, since the connection circuit 131 and the power supply electrode 120 are both disposed on the second mounting surface 111 and can be directly connected, the power supply base film 110 does not need to be perforated, which can reduce the manufacturing cost of the power supply base film 110 and simplify the connection operation between the connection circuit 131 and the power supply electrode 120, thereby improving the production efficiency of the power supply sheet 10. Of course, in other embodiments, the connection circuit may be provided on the first mounting surface.
