Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
As shown in fig. 1 to 5, an embodiment of the present invention provides a folding electronic device, which includes a first folding portion 1 and a second folding portion 2, wherein the first folding portion 1 includes a first battery 12 and a first switch 13, the first battery 12 is installed in a first housing 11, and the first battery 12 is connected to the first switch 13; the second folding part 2 includes a second battery 22 and a second switch 23, the second battery 22 is installed in the second casing 21, and the second battery 22 is connected with the second switch 23; for the purpose of charging the first battery 12 and the second battery 22, the folding electronic device is further provided with a charging section 3, the first battery 12 is connected with the charging section 3 to charge the first battery 12 and the second battery 22 through the charging section 3; the first housing 11 and the second housing 21 are connected in a rotatable manner, so that the folding electronic device can be switched between a folding state and an unfolding state under the condition that a user needs the folding electronic device; meanwhile, in the folded state of the first and second housings 11 and 21, the first and second switches 13 and 23 are communicated with each other to connect the first and second batteries 12 and 22 in parallel, so as to manage and connect the first and second batteries 12 and 22 with the assistance of other components or elements. Certainly, the foldable electronic device provided in the embodiment of the present invention may further include other components, such as a display, a speaker, a camera, and other power consuming components, and the text is considered to be concise, and therefore, details are not described here again.
Specifically, the first battery 12 and the second battery 22 may be lithium batteries, and parameters such as a rated voltage, a rated current, and a total electric quantity of the first battery 12 and the second battery 22 may be flexibly selected according to actual situations, and each parameter of the first battery 12 and each parameter of the second battery 22 may be the same or different; the first casing 11 and the second casing 21 can be made of hard materials such as plastics or metals, and both have certain installation spaces to accommodate and install the first battery 12 and the second battery 22 respectively; the first switch 13 and the first battery 12 can be connected by a wire, and the first switch 13 can be installed on a side surface of the first housing 11 facing the second housing 21, and correspondingly, the second switch 23 can also be installed on a surface of the second housing 21 facing the first housing 11, so that when the first housing 11 and the second housing 21 are in a folded state, the first switch 13 and the second switch 23 can be communicated with each other, which is convenient and fast, and the bridging is not needed by other parts, and the structure is simple.
Further, as shown in fig. 2, both the first switch 13 and the second switch 23 may be magnetic switches, and the first switch 13 may be located on the back of the first casing 11, and the second switch 23 may be located on the back of the second casing 21, so that when the first casing 11 and the second casing 21 are in the folded state, the connection relationship between the first switch 13 and the second switch 23 is ensured to have high reliability by virtue of the magnetic attraction between the first switch 13 and the second switch 23, thereby preventing the disconnection of the first switch 13 and the second switch 23 caused by vibration or other factors, which causes the interconnection failure between the first battery 12 and the second battery 22, and further adversely affecting the normal operation of the foldable electronic device. The charging part 3 may be a common USB charging port, which may be connected to the first battery 12 by a wire to charge the first battery 12; accordingly, the charging section 3 may also charge the second battery 22 by putting the first casing 11 and the second casing 21 in a folded state, or putting the first switch 13 and the second switch 23 in communication by means of another connecting member.
Further, the purpose of improving the charging and discharging efficiency of the first battery 12 and the second battery 22 can be achieved by controlling and managing the charging and discharging processes of the first battery 12 and the second battery 22, preferably, a battery management control assembly can be further provided in the foldable electronic device provided in the embodiment of the present invention, and in the assembling process of the foldable electronic device, the battery management control assembly can be simultaneously connected to the first battery 12 and the second battery 22, so that in the using and charging processes of the foldable electronic device, the discharging and charging processes of the first battery 12 and the second battery 22 are monitored, controlled and managed, the charging and discharging efficiency of the first battery 12 and the second battery 22 is improved, and the charging and discharging processes of the first battery 12 and the second battery 22 are managed and controlled, so as to improve the service lives of the first battery 12 and the second battery 22.
In order to further enhance the refinement degree of the management and control of the first battery 12 and the second battery 22, preferably, as shown in fig. 1 and 4, the battery management control assembly may include a first management and control chip 5 and a second management and control chip 6, wherein the first management and control chip 5 is connected to the first battery 12, and the second management and control chip 6 is connected to the second battery 22. Specifically, the structures and the compositions of the first control chip 5 and the second control chip 6, the internal programs and the like can be the same, so that the design and the production difficulty of the whole folding electronic device can be reduced, and the production cost can be effectively reduced. In the using and charging process of the folding electronic device, the first control chip 5 controls the first battery 12 independently, and the second control chip 6 controls the second battery 22 independently, so as to further improve the accuracy and refinement degree of the monitoring, controlling and managing results of the batteries. Preferably, a communication connection relationship may be formed between the first management and control chip 5 and the second management and control chip 6, so that in the working process of the foldable electronic device, information exchange and information integration can be performed between the first management and control chip 5 and the second management and control chip 6, and thus an optimal power supply solution is determined according to respective real-time states of the first battery 12 and the second battery 22, so that the working performance of the foldable electronic device is maximized.
As described above, when the first housing 11 and the second housing 21 are in the folded state, the first switch 13 and the second switch 23 are communicated, so that the first battery 12 and the second battery 22 are in a parallel connection relationship, in this case, when the actual voltages of the first battery 12 and the second battery 22 are different, a situation that one battery charges the other battery may occur, and in the foregoing charging process, a situation that the total electric quantity of the two batteries is reduced due to heat release from charging and the like inevitably occurs, which will certainly reduce the overall performance of the folding electronic device, preferably, in the folding electronic device provided by the embodiment of the present invention, the first control chip 5 may include the first anti-mutual-charging element therein, and the first anti-mutual-charging element is connected between the first battery 12 and the first switch 13; correspondingly, a second mutual charging prevention element is arranged in the second control chip 6 and connected between the second battery 22 and the second switch 23; so that the first battery 12 and the second battery 22 can be brought into a parallel relationship only when the charging section 3 is operated by the first and second anti-mutual-charge elements; in other words, even when the first switch 13 and the second switch 23 are in the on state, if the charging portion 3 does not charge the first battery 12 or the second battery 22, the first battery 12 and the second battery 22 will not be in the parallel connection, which can prevent the first battery 12 and the second battery 22 from being charged with each other, thereby maximally ensuring that the total amount of electricity of the two will not be lost without any cause.
Specifically, the first and second anti-mutual-charging elements may be provided therein with respective means for acquiring whether the charging section 3 is in an operating state, so as to bring the first and second batteries 12 and 22 into a parallel relationship when the charging section 3 is in the operating state. It should be noted that the premise that the first battery 12 and the second battery 22 form a parallel connection relationship is that the first switch 13 and the second switch 23 are in a connected state; alternatively, the first anti-mutual-charging element and the second anti-mutual-charging element may also complete the control process through a set program or software, which is not limited herein. Preferably, as shown in fig. 5, the first and second anti-mutual-charging elements may each include a field effect transistor therein, so that the field effect transistor is closed under a set condition, and the first battery 12 and the second battery 22 are connected in parallel, where the set condition is that the charging unit 3 is in an operating state, and when the charging unit 3 does not operate, the first battery 12 can also supply power to a main power supply system such as a display screen through the conducting circuit, and correspondingly, the second battery can also supply power to an auxiliary power supply system through the conducting circuit. Furthermore, the field effect transistor may be provided with a diode so that, in the event of a large instantaneous reverse current in the circuit, the reverse current is conducted away by means of the diode without breaking down the field effect transistor.
In order to make the charging operation for the first battery 12 and the second battery 22 more flexible and convenient, preferably, as shown in fig. 3, the foldable electronic device provided in the embodiment of the present invention may further include an auxiliary charging unit 4, and the second battery 22 is connected to the auxiliary charging unit 4, so that during the charging process of the foldable electronic device, even if the first switch 13 and the second switch 23 are disconnected, that is, there is no electrical connection between the first battery 12 and the second battery 22, the first battery 12 may be charged by the charging unit 3, and the second battery 22 may be charged by the auxiliary charging unit 4, so that the charging process is prevented from being limited by the folded and unfolded state of the foldable electronic device, which may improve the charging flexibility of the foldable electronic device; meanwhile, when the charging part 3 and the auxiliary charging part 4 work together, the charging speed of the folding electronic equipment can be increased, and the charging time is shortened.
Specifically, the charging unit 3 and the auxiliary charging unit 4 may have the same or different structures. A preferred embodiment is that the charging unit 3 includes a USB (Universal Serial Bus) charging port, and the auxiliary charging unit 4 includes a magnetic-suction charging port, in which case, in addition to providing a charging function for a user, the USB charging port enables the user to connect the foldable electronic device with other devices through the USB charging port, so as to perform data transmission therebetween, and the USB charging port has relatively high adaptability, so that the user can easily find a charger adapted to the foldable electronic device even if the user does not carry the charger with him, and the convenience of use is relatively high; and magnetism is inhaled preventing of charging mouthful and is fallen and waterproof performance is higher relatively, saves installation space, and the adsorption process when charging to and the removal process when stopping charging is comparatively simple and convenient, and life is higher relatively.
As described above, since there is no power exchange between the first battery 12 and the second battery 22, and the power consumption components connected to the first battery 12 and the second battery 22 are different, there may be a case where the remaining power of the first battery 12 and the remaining power of the second battery 22 are different due to differences in total capacity, output time, output power, and the like of the two during operation. Further, in order to prevent one of the first battery 12 and the second battery 22 from being unable to be charged in time even if the power of the one of the first battery 12 and the second battery 22 is too low during the charging process, the foldable electronic device according to the embodiment of the present invention may further include a charging control portion (not shown in the figure) connected between the charging portion 3 and the first battery 12, and during the use and charging process of the foldable electronic device, the charging control portion may obtain the remaining power information of the first battery 12 and the second battery 22, and further during the charging process, the charging control portion may determine the priority charging target of the charging portion 3 by changing the connection relationship between the charging portion 3 and the first battery 12 and the second battery 22 according to the remaining power information, so as to prevent the situation that even one of the first battery 12 and the second battery 22 is low, the timely power cannot be supplemented during the charging process.
Specifically, in the design and production assembly process of the folding electronic device, a setting component or a setting program may be installed in the charging control portion, so that the charging control portion can change the on-off relationship between the charging portion 3 and the first battery 12 and the second battery 22, thereby controlling the charging portion 3 to charge the corresponding battery in different states.
More specifically, when the amount of electricity (proportion) of the first battery 12 is smaller than the amount of electricity (proportion) of the second battery 22, the charge control portion controls the charging portion 3 to charge the first battery 12 preferentially; when the amounts (ratios) of the electric power of the first battery 12 and the second battery 22 are substantially equal, the charging portion 3 can be caused to charge the first battery 12 and the second battery 22 at the same time. In addition, according to the actual setting rule, when a special situation occurs, the charging sequence may also be controlled according to the aforementioned setting rule, for example, when the component connected to the first battery 12 is a priority power supply component, such as in a folding screen mobile phone, it usually includes a main screen and an auxiliary screen, the first battery 12 alone supplies power to the main screen, and the second battery 22 alone supplies power to the auxiliary screen, if the content displayed by the main screen is important, or the priority of the main screen is higher than that of the auxiliary screen, even if the electric quantity (ratio) of the second battery 22 is slightly less than that of the first battery 12, the charging control part may also control the charging part 3 to charge the first battery preferentially, for this reason, a person skilled in the art may set the corresponding rule according to the actual requirement, and details are not repeated here.
In the case where the charging unit 3 and the auxiliary charging unit 4 are provided in the foldable electronic device at the same time, the charging control unit may control both the charging unit 3 and the auxiliary charging unit 4 at the same time by changing the connection relationship, and further, the charging unit 3 and the auxiliary charging unit 4 may charge only one of the first battery 12 and the second battery 22 having a lower electric quantity (ratio) at the same time under the condition that the first switch 13 and the second switch 23 are connected, and the charging control unit may control the charging unit 3 to charge only the first battery 12 and the auxiliary charging unit 4 to charge only the second battery 22 when the electric quantities (ratios) of the first battery 12 and the second battery 22 are substantially equal to each other. Alternatively, the charging part 3 and the auxiliary charging part 4 may be configured to charge the first battery 12 or the second battery 22 at the same time according to a preset rule or a user requirement, even if the amount (ratio) of electricity of the former charged one is higher than that of the other, so as to adapt to a usage scenario of the device or a usage requirement of the user.
In order to enable the user to know the remaining power of the first battery 12 and the second battery 22 more clearly, as shown in fig. 4, preferably, the foldable electronic device provided in the embodiment of the present invention may further include a first power display 7 and a second power display 8, where the first power display 7 is connected to the first battery 12, and the second power display 8 is connected to the second battery 22, so that during the operation of the foldable electronic device, the user can clearly know the real-time remaining power of the first battery 12 and the second battery 22 through the first power display 7 and the second power display 8, and further determine the subsequent use frequency or take corresponding measures according to the real-time remaining power of the first battery 7 and the second battery 22, such as whether to turn on the power saving mode, or charge the first battery 12 and/or the second battery 22. Meanwhile, in the charging process, by means of the first electric quantity display part 7 and the second electric quantity display part 8, the user can also clearly acquire information such as the charging state and the real-time electric quantity of the first battery 12 and the second battery 22, and user experience is improved.
Specifically, the first power display unit 7 and the second power display unit 8 may be both located on a same component, such as a display screen, and display the real-time remaining power and the charge/discharge status of the first battery 12 and the second battery 22 in an image and/or data display manner; of course, the real-time power of the first battery 12 and the real-time power of the second battery 22 may be displayed in other display manners, for example, the first power display unit 7 and the second power display unit 8 may also be display lamps, and the two display lamps may display whether the first battery 12 and the second battery 22 are in the charging state by changing the color of the display lamps, and may also display the real-time remaining power of the first battery 12 and the second battery 22 by lighting different numbers of display lamps, for this, a person skilled in the art may determine according to the actual structure of the foldable electronic device, and is not limited specifically herein.
