[0054] The technical solution of the present application is further elaborated in detail below in conjunction with the accompanying drawings and specific embodiments of the specification.

[0055] like Figure 1 As shown, this embodiment provides an electronic device, including:

[0056] The device housing 11 is formed with a first accommodating cavity;

[0057] The functional module 12 is at least partially located in the first accommodating cavity;

[0058] The battery module 13 is located in the first accommodating cavity, and the battery module 13 includes:

[0059] The battery housing 131 forms a second accommodating cavity;

[0060] A battery assembly 132, located in the second accommodation cavity, for storing electrical energy or releasing stored electrical energy;

[0061] The charging assembly 133 is located in the second accommodating cavity and is connected to the battery assembly 132 , and is used to charge the battery assembly 132 by transmitting wireless signals with a power supply device.

[0062] The present embodiment provides an electronic device, which may be a laptop computer, a tablet computer, a laptop and tablet two-in-one computer, or various mobile devices such as a large-screen mobile phone.

[0063] In this embodiment, the device housing 11 included in the electronic device determines the visual effect of the overall appearance of the electronic device.

[0064] The device housing 11 forms a containing cavity, which is called the first containing cavity and can serve as the largest containing cavity of the electronic device.

[0065] The functional module 12 may be a module capable of realizing various functions. Energy consumption will be generated when realizing the functions, and such energy consumption may need to be provided by the power supply of the battery module 13 .

[0066] The functional module 12 includes but is not limited to at least one of the following:

[0067] Processor, including but not limited to: single-core or multi-core CPU, GPU, embedded (EC) controller, microprocessor MCU, or various programmable arrays, etc.;

[0068] Displays, including but not limited to: liquid crystal displays, electronic ink displays, and OLED displays;

[0069] Sensors, including but not limited to: position sensors, distance sensors;

[0070] Collectors, including but not limited to: image collectors, audio collectors;

[0071] Input module, used to collect user input, including but not limited to: keyboard, touchpad, touch screen, fingerprint module, pointing stick.

[0072] The keyboard may include letter keys, number keys, punctuation keys and / or special keys, and may receive characters, numbers, punctuation keys or trigger special functions input based on key operations.

[0073] The touch panel can detect clicks and / or slides, thereby triggering the display or hiding of the mouse cursor of the electronic device, or moving the cursor.

[0074] The fingerprint module is capable of collecting fingerprints.

[0075] The pointing stick can also be an input module for adjusting the cursor on the display screen based on the user's input. The input module includes but is not limited to a dot-shaped object embedded in the middle of a physical keyboard.

[0076] The above is only an example of the functional module 12 .

[0077] In some embodiments, the functional module 12 is at least partially located in the first accommodating cavity.

[0078] For example, the processor and the like do not need to interact with the user or the first type of functional module 12 for the user to view is completely located in the first housing cavity. For another example, the display and the like need to be viewed by the user, or the input module needs to be touched by the user, etc., the first type of functional module 12 is partially located in the first housing cavity, and the other part can be displayed on the outside of the electronic device by providing an opening on the first housing cavity.

[0079] In this embodiment, the electronic device further includes a battery module 13. In this embodiment, the battery module 13 includes: a battery assembly 132 composed of one or more battery cells, and a charging assembly 133 capable of charging the battery assembly 132.

[0080] In this embodiment, the charging component 133 is capable of receiving wireless signals, converting the wireless signals into internal electrical signals, and converting the electromagnetic energy of the wireless signals into electrical energy to supply power to the battery component 132 .

[0081] In this embodiment, the charging assembly 133 and the battery assembly 132 are located together in the second accommodation cavity formed by the battery housing 131. Specifically, the charging assembly 133 and the battery assembly 132 are arranged adjacent to each other, for example, the charging assembly 133 is located outside the battery assembly 132, and more specifically, the charging assembly 133 is located on the outer surface of the battery assembly 132. In this way, the distance between the charging assembly 133 and the battery assembly 132 of the battery module 13 is limited, for example, less than a preset distance, less than the maximum distance that can be provided by the second accommodation cavity, etc.

[0082] In this embodiment, the battery housing 131 is a non-shielding housing that does not shield wireless signals, for example, a plastic housing, which allows wireless signals for charging to pass successfully.

[0083] In this embodiment, the charging component 133 can be charged based on wireless signals. This, on the one hand, facilitates the replacement of battery modules and simplifies electronic devices that were originally not capable of being charged based on wireless signals. The battery modules that were originally not capable of being charged based on wireless signals are replaced with battery modules that can be charged based on wireless signals according to the present application, thereby realizing easy replacement of battery modules in electronic devices.

[0084] On the other hand, the charging component is located inside the battery casing of the battery module and does not need to be set on the main board of the electronic device or occupy area on the main board, thereby reducing compatibility issues with existing electronic devices caused by setting it on the main board, reducing the large amount of work required to redesign the electronic device due to readjusting the layout of the main board or increasing the layout of the main board, and simplifying the upgrade of the electronic device.

[0085] On the one hand, the charging component is not set on the main board of the electronic device, because the charging signal interferes with other circuits on the main board, thereby reducing the battery interference (Electromagnetic Interference, EMI) and / or Radio Frequency Interference (Radio Frequency Interference, RFI) caused by mutual interference. At the same time, since the charging component generates heat during the charging process, separating it from the main board can reduce the heat accumulation on the main board caused by the charging component.

[0086] In some embodiments, the charging component 133 includes:

[0087] The charging coil 1331 is used to sense the wireless signal and convert it into a charging signal, and charge the battery assembly 132 based on the charging signal;

[0088] like Figure 3 As shown, the functional module 12 includes:

[0089] The input module includes: an input collection area, which is exposed on the outer surface of the electronic device through an opening provided on the first surface of the device housing 11;

[0090] The battery module 13 is located on a side of the input module away from the first surface, and a side of the battery module 13 provided with the charging coil 1331 faces a second surface of the device housing 11 , wherein the second surface is opposite to the first surface.

[0091] The charging coil 1331 can sense or receive the wireless signal, and convert the electromagnetic energy of the alternating magnetic field carried by the wireless signal into electrical energy, for example, into alternating current electrical energy corresponding to the alternating current signal.

[0092] In some embodiments, the input module includes but is not limited to: a touchpad, which is different from the touch screen of a mobile phone. The touchpad can be made of a touch panel material of a non-transparent and non-shielding material, which can detect the user's touch operation and send the detected touch operation to the processing module of the electronic device to control the implementation of various functions of the electronic device, thereby realizing the detection of user input.

[0093] In some other embodiments, the input module may further include: a keyboard or a touch bar other than the touch module. In conclusion, in this embodiment, the input module is not limited to the touch panel.

[0094] In this embodiment, the wireless charging coil is disposed at a position corresponding to the input and output module, so as to reduce the shielding effect of the device housing 11 on the wireless charging coil and ensure the charging efficiency of the battery module 13 .

[0095] In some embodiments, the charging coil 1331 is a hollow annular charging coil 1331 , wherein the hollow portion of the annular charging coil 1331 is located on a side of the input module away from the first surface.

[0096] In this embodiment, the charging coil 1331 is a hollow ring-shaped charging coil 1331 , and a ring body of the charging coil 1331 is formed outside the hollow ring. The ring body is formed by multiple turns of the charging coil 1331 .

[0097] In this way, when the battery assembly 132 expands due to heat, the middle part will expand first relative to the two end parts, and the charging coil is a ring-shaped hollow charging coil. In this way, the expanded middle part of the battery assembly 132 can enter the hollow part, so that other items in the electronic device will not be squeezed.

[0098] In some embodiments, Figure 2 As shown, the charging component 133 further includes:

[0099] a rectifier assembly 1332, connected to the charging coil 1331 and located on a different side of the battery assembly 132 in the first direction from the charging coil 1331, for rectifying the charging signal;

[0100] A charging subassembly 1333, connected to the rectifier subassembly 1332 and located on a different side of the battery assembly 132 from the charging coil 1331, for transmitting the rectified charging signal to the battery assembly 132 to charge the battery assembly 132;

[0101] The rectifier subassembly 1332 and the charging subassembly 1333 are located at opposite ends of the input module in a second direction, wherein the second direction is perpendicular to the first direction.

[0102] The first trimming subassembly herein includes one or more rectifiers, including but not limited to a full-bridge rectifier or a half-bridge rectifier.

[0103] After the charging coil 1331 converts the wireless signal into an AC signal for transmission in the line, the AC signal is converted into a DC signal capable of charging the battery assembly 132 through a sorting subassembly.

[0104] The charging subassembly 1333 is connected to the rear end of the sorting subassembly, and can process the charging signal rectified by the sorting subassembly through voltage transformation and the like, and then provide it to the battery assembly 132 to charge the battery assembly 132 .

[0105] In this embodiment, the rectifier subassembly 1332 and the charging subassembly 1333 may generate heat due to the passage of current during the process of charging the battery assembly 132. In order to reduce the phenomenon that the rectifier subassembly 1332 and the charging subassembly 1333 are centrally arranged, resulting in poor heat dissipation due to heat accumulation, in this embodiment, the rectifier subassembly 1332 and the charging subassembly 1333 are arranged on different sides of the battery assembly 132, which are on different sides of the stacking direction of the charging assembly 133 and the battery assembly 132. In other words, the rectifier subassembly 1332 and the charging subassembly 1333 are located at different ends of the same side of the battery assembly 132.

[0106] In some embodiments, a gap is provided between the charging subassembly 1333 and the rectifier subassembly 1332. This gap, to a certain extent, provides a larger space for the heat dissipation of the charging subassembly 1333 and the rectifier subassembly 1332. On the one hand, it accelerates the heat dissipation of the entire battery assembly 132; on the other hand, compared with the heat accumulation caused by arranging the charging subassembly 1333 and the rectifier subassembly 1332 with larger heat generation at one end, it reduces the phenomenon of excessive temperature difference in various parts of the entire battery module 13, thereby achieving thermal balance of the entire battery module 13.

[0107] In this embodiment, the first direction is the stacking direction of the battery components 132 and the charging components 133 in the battery module 13; and the second direction is a direction perpendicular to the first direction.

[0108] In this embodiment, the housing of the battery module may be a special-shaped housing, for example, a cross section of the battery housing is concave-shaped, such as Figure 3 As shown,

[0109] In addition, since the rectifier subassembly 1332 and the charging subassembly 1333 are disposed on the opposite side of the charging coil 1331, it is equivalent to that the rectifier subassembly 1332 and the charging subassembly 1333 are disposed close to the input module. Figure 3 As shown, the protruding portion of the input module toward the inside of the device housing can be embedded in the gap between the rectifier subassembly 1332 and the charging subassembly 1333. In this way, compared with when the rectifier subassembly 1332 and the charging subassembly 1333 are not separated, the overall thickness of the electronic device can be reduced, thereby achieving a lighter and thinner electronic device.

[0110] In some embodiments, the charging component 133 further includes:

[0111] The control subassembly is located in the second accommodating cavity and is located on the same side of the second direction of the input module as the rectifier subassembly 1332 , and is used to control the working state of the charging subassembly 1333 .

[0112] The state of the control charging subcomponent 1333 here includes but is not limited to:

[0113] the conduction state of the charging subassembly 1333;

[0114] The disconnected state of the charging subassembly 1333.

[0115] If the charging subcomponent 1333 is in the on state, the connection between the charging component 133 and the battery component 132 is on, and the charging component 133 can charge the battery component 132 through the connection; if the charging subcomponent 1333 is in the off state, the connection between the charging component 133 and the battery component 132 is off, and the charging component 133 cannot charge the battery component 132.

[0116] The control subassembly may include but is not limited to a charging controller, which may be connected to a controlled switch included in the charging subassembly 1333, and control the state of the charging subassembly 1333 by providing a control signal to the controlled switch. For example, the controlled switch includes but is not limited to: one or more MOS tubes, etc.

[0117] In some embodiments, heat dissipation of the battery module 13 can be achieved by heat exchange with gases such as air.

[0118] In other embodiments, the battery module 13 may also dissipate heat through liquid cooling. For example, a liquid cooling component containing a heat dissipation liquid is provided inside or around the battery module 13 to dissipate heat through heat exchange between a liquid heat dissipation medium (e.g., water) and the battery module 13.

[0119] In this embodiment, the rectifier subassembly 1332 and the charging subassembly 1333 are spaced apart. Since the rectifier subassembly 1332 and the charging subassembly 1333 are spaced apart, the contact area between the rectifier subassembly 1332 and the charging subassembly 1333 and the surroundings is larger, thereby increasing the heat dissipation area, thereby accelerating heat dissipation. Moreover, this split arrangement is more conducive to achieving thermal balance of the entire battery module 13 than being centrally arranged in the battery module 13.

[0120] In some embodiments, the battery module 13 further includes:

[0121] The heat dissipation component, the rectifier subcomponent 1332 and the charging subcomponent 1333 are distributed on different sides of the battery component 132 in the first direction, and are used for heat dissipation of the battery module 13 .

[0122] The heat dissipation component, and the high heat-generating finishing subcomponent and charging subcomponent 1333 are located on different sides in the stacking direction. The high thermal conductivity of the heat dissipation component can be utilized to transfer heat to the other side to achieve rapid heat dissipation.

[0123] In some embodiments, the heat dissipation component can also be wrapped around multiple sides of the battery component 132 and the charging component 133 to achieve rapid heat conduction and heat dissipation.

[0124] like Figure 4A , Figure 4B and Figure 4C As shown, this embodiment provides a battery module, including:

[0125] A battery assembly 21 for storing electrical energy or releasing stored electrical energy;

[0126] A charging assembly 22, connected to the battery assembly 21, and used to charge the battery assembly 21 by transmitting wireless signals with a power supply device;

[0127] The battery module has at least two thicknesses in the stacking direction of the battery assembly 21 and the charging assembly 22 .

[0128] The battery assembly 21 includes a battery pack.

[0129] The charging component 22 provided in the aforementioned embodiment is a charging structure capable of charging based on wireless signals.

[0130] In this embodiment, the battery assembly 21 and the charging assembly 22 are stacked, and the cross-section in the stacking direction of the battery assembly 21 and the charging assembly 22 has a height difference, which means that the battery module is no longer a regular or standard shape. For example, the battery module is no longer a standard rectangle, but a special-shaped battery module. In short, the battery module provided in this embodiment forms a whole; in this way, the replacement of the battery module is convenient, and the electronic device that was originally not capable of charging based on wireless signals is simplified. The battery module that was originally not capable of charging based on wireless signals is replaced with the battery module that can be charged based on wireless signals in this application, so as to realize the simple replacement of the battery module in the electronic device; and the battery module as a whole has at least two thickness differences in the stacking direction, which can match the protrusions in the electronic device, so that the thickness of the electronic device can be thinned as a whole compared to the battery module without height difference.

[0131] In some embodiments, the at least two thicknesses make the cross-section of the battery module be in a stepped shape, a trapezoidal shape, or a concave shape with two ends and a thin middle.

[0132] refer to Figure 4C As shown, the charging component 22 includes:

[0133] A rectifier assembly 222, located at a first end of a first side of the battery assembly 21;

[0134] a charging subassembly 223, located at a second end of the first side of the battery assembly 21, wherein the second end and the first end are opposite ends to each other, wherein there is a separation space between the charging subassembly 222 and the rectifying subassembly 222;

[0135] The cross section of the battery module at the position where the separation space is provided has a first thickness;

[0136] A cross section of the battery assembly 21 at a position outside the separation space has a second thickness, wherein the second thickness is different from the first thickness.

[0137] In some embodiments, the battery module further comprises:

[0138] The battery housing is formed with a housing cavity for housing the battery assembly 21 and the charging assembly 22 .

[0139] A rectifier assembly 222, connected to the wireless charging coil 221 and located on a different side of the battery assembly 21 from the wireless charging coil 221, for rectifying the charging signal;

[0140] A charging subassembly 223, connected to the rectifier subassembly 222 and located on a different side of the battery assembly 21 from the wireless charging coil 221, for transmitting the rectified charging signal to the battery assembly 21 to charge the battery assembly 21;

[0141] The rectifier subassembly 222 and the charging subassembly 223 are located at opposite ends of the battery assembly 21 .

[0142] In short, you can refer to Figure 4C As shown, the charging coil 221 and the charging subassembly 223 are located on different sides of the charging assembly 22 and the battery assembly 21 in the stacking direction.

[0143] In some embodiments, the battery module further comprises:

[0144] The connection interface can be wired to the functional module and provide the electric energy stored in the battery assembly 21 to the functional module.

[0145] The functional modules may be various modules in the electronic device that generate power consumption.

[0146] Several specific examples are provided below in combination with any of the above embodiments:

[0147] Example 1:

[0148] If the circuit board and charging coil are simply stacked directly on the motherboard, the thickness of the whole device will increase. In addition, there may be interference between wireless charging and the motherboard circuit, and EMI and RFI problems, as well as heat dissipation problems, need to be solved.

[0149] In this solution, the wireless charging module is added to the battery pack, and the existing space of the notebook is utilized. Without increasing the thickness of the electronic device (e.g., notebook (NB)) and without reducing the battery capacity, the electronic device without the wireless charging function can be upgraded to an electronic device with the wireless charging function by simply replacing the battery.

[0150] This design also separates the wireless charging part from the motherboard, making the motherboard design simpler without having to consider heat dissipation and interference issues. These issues are solved in the battery design.

[0151] In the current design of notebooks, there is still 3mm of space between the C cover and the battery cell on both sides of the touch panel, but the touch surface in the middle is in contact with the battery cell. Because the battery cell is flat, the space on both sides is not used. Therefore, the added wireless charging Rx and battery charger board can be placed on both sides, between the battery cell and the C cover.

[0152] The wireless charging Rx and battery charger boards are placed on both sides of the touch panel for thermal balance. The components face the battery, and the aluminum sheet at the bottom of the battery pack is used to dissipate heat. The temperature rise of the C cover of the electronic device is reduced as much as possible, and the heat is dissipated through the D Cover to reduce the temperature of the C cover that has a higher probability of contact with the user's hand.

[0153] The wireless charging charging coil is a flexible printed circuit board (FPC) + ferrite, which is placed on top of the battery, between the battery and the D cover, so that the signal will not be shielded by the battery. The charging coil is connected to the PCBA on both sides (corresponding to the circuit boards where the Wireless charging Rx and battery charger are located) through the flexible printed circuit board (FPC). The charging coil can be placed in the reserved expansion space of the battery. Using Airfuel's wireless charging technology, the charging coil is only wound around the edges and can be hollowed out in the middle. The battery expands mainly in the center, and the edges will not expand. Therefore, the charging coil does not need to increase the thickness of the electronic device. Figure 7 A schematic diagram of a hollow charging coil.
