Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a terminal. Background Art

[0002] In a terminal, two batteries can be used to supply power to the main board.

[0003] Since different batteries are connected to the main board in different ways, there are differences in the impedance from different batteries to the main board. If the devices on the main board require pulsed current, it will cause the supply voltage of the battery to change periodically. In this case, if the impedance between the battery and the main board is large, it will cause a large fluctuation amplitude of the supply voltage, and further cause the ceramic capacitor hanging on this path to drive the printed circuit board (PCB) to vibrate. Summary of the Utility Model

[0004] To overcome the problems existing in the related art, the present disclosure provides a terminal that can solve the above problems.

[0005] According to a first aspect of an embodiment of the present disclosure, a terminal is provided. The terminal includes: a first battery, a second battery, a switch control module, and a main board. The devices on the main board include a power consumption unit, and the supply current of the power consumption unit in the working state is pulsed current. Among them,

[0006] The first battery is connected to the main board through a first connector to supply power to the devices on the main board.

[0007] The second battery is connected to the main board through a transfer line to supply power to the devices on the main board. Among them, the impedance value of the power supply line between the second battery and the power consumption unit is greater than the impedance value of the power supply line between the first battery and the power consumption unit.

[0008] The switch control module is disposed on the transfer line and is used to disconnect the transfer line when the power consumption unit is in the working state.

[0009] In some embodiments, a first on-board power supply line and a second on-board power supply line are provided on the main board. One end of the first on-board power supply line is connected to the power consumption unit, and the other end is connected to the first connector. One end of the second on-board power supply line is connected to the power consumption unit, and the other end is connected to the transfer line. After the first on-board power supply line and the second on-board power supply line converge, they jointly supply power to the power consumption unit. Among them, the first on-board power supply line, the second on-board power supply line, and the transfer line form an equalization line between the first battery and the second battery, which is used to equalize the voltages of the second battery and the first battery.

[0010] In some embodiments, the terminal further includes: a current management chip, which is arranged on the power supply line of the first board and is used to limit the current of the second battery replenishing the first battery to not exceed a preset threshold.

[0011] In some embodiments, the power consumption unit includes a power amplifier for amplifying the radio frequency signal.

[0012] In some embodiments, the terminal includes a folding screen terminal, the folding screen terminal includes a first body and a second body, the mainboard and the first battery are arranged on the first body, and the second battery is arranged on the second body.

[0013] In some embodiments, the terminal further includes: a sub-board, the sub-board is disposed on the second body, and at least a portion of the switching line is located on the sub-board.

[0014] In some embodiments, the space occupied by the sub-board in the second body is smaller than the space occupied by the mainboard in the first body, the space occupied by the second battery in the second body is larger than the space occupied by the first battery in the first body, and the capacity of the second battery is larger than the first battery.

[0015] In some embodiments, the transfer circuit includes: an on-board transfer circuit segment located on the sub-board and an under-board transfer circuit segment located between the sub-board and the main board; wherein one end of the on-board transfer circuit segment is connected to the second battery through a second connector, and the other end is connected to the under-board transfer circuit segment.

[0016] In some embodiments, the switch control module is disposed on the on-board transfer line segment.

[0017] In some embodiments, the folding screen terminal is an up-down folding screen terminal.

[0018] In some embodiments, the switch control module is further configured to turn on the transfer line when the power consumption unit is in a non-working state.

[0019] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0020] The main board of the present disclosure is powered by a first battery and a second battery, and the impedance value of the power supply line between the second battery and the power consumption unit on the main board is relatively large. When the power consumption unit is in the working state and demands pulsed current, the switch control module arranged between the second battery and the main board can disconnect the line, thereby preventing the second battery from supplying power to the main board through the line with a relatively large impedance value, and only selecting the first battery to supply power through the line with a relatively small impedance value, thus avoiding the problem that the ceramic capacitor drives the main board to vibrate due to a large fluctuation in the supply voltage.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

[0031] In the prior art, some terminals can choose to use two parallel batteries to supply power to the main board of the terminal.

[0032] Figure 1 It is a schematic diagram of an existing terminal in the related art.

[0033] As Figure 1 shown, the first battery 110 and the second battery 120 jointly supply power to the main board 130, and the power consumption unit 131 is arranged on the main board 130. When the power consumption unit 131 is in the working state and a pulsed current is required, power can be taken from the first battery 110 and the second battery 120 simultaneously based on the power supply line.

[0034] However, since the second battery 120 is not directly connected to the main board 130 through a connector, but is pulled to the main board 130 through an adapter line, the path impedance of the power supply line where the second battery 120 is located is relatively large. Due to Ohm's law U = I × R, the voltage fluctuation amplitude on the power supply line of the second battery 120 is relatively large. In this case, the ceramic capacitor hanging on this path can cause the main board to vibrate, generate noise, and affect the user experience.

[0035] To solve the above problems, the present disclosure proposes a terminal.

[0036] Figure 2 It is a schematic structural diagram of a terminal shown according to an embodiment of the present disclosure. The terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices.

[0037] As Figure 2As shown, the terminal includes: a first battery 110, a second battery 120, a switch control module 140, and a main board 130. The components on the main board 130 include a power consumption unit 131, and the supply current of the power consumption unit 131 in the working state is a pulsed current. Among them,

[0038] The first battery 110 is connected to the main board 130 through a first connector 111 to supply power to the components on the main board 130.

[0039] The second battery 120 is connected to the main board 130 through an adapter line 121 to supply power to the components on the main board 130. Among them, the impedance value of the power supply line between the second battery 120 and the power consumption unit 131 is greater than the impedance value of the power supply line between the first battery 110 and the power consumption unit 131.

[0040] The switch control module 140 is arranged on the adapter line 121 and is used to disconnect the adapter line 121 when the power consumption unit 131 is in the working state.

[0041] In some embodiments, the switch control module 140 is further used to: conduct the adapter line 121 when the power consumption unit 131 is in the non - working state.

[0042] When the power consumption unit 131 is in the non - working state, there is no board vibration problem in the terminal, and the first battery and the second battery can be used to jointly supply power to the main board.

[0043] In some embodiments, the first battery 110 and the second battery 120 jointly supply power to the main board 130.

[0044] When the components on the main board 130 need power supply, they can obtain power from the first battery 110 and the second battery 120.

[0045] In some embodiments, the first battery 110 and the second battery 120 are connected in parallel.

[0046] Due to the limitation of the design space of the terminal, it is difficult to use a single large - capacity battery in some terminals. At this time, two batteries can be set at different positions and the two batteries can be used to supply power in parallel, so as to expand the total battery capacity of the terminal.

[0047] As Figure 2 shown, in some embodiments, the first battery 110 and the second battery 120 are connected to a power supply point 150. When any component on the main board 130 needs to obtain power, it can obtain power from the power supply point 150.

[0048] If the component needs pulsed current, it also obtains pulsed current from the power supply point 150.

[0049] In some embodiments, an impedance value of a power supply line between the second battery 120 and the power consumption unit 131 is greater than an impedance value of a power supply line between the first battery 110 and the power consumption unit 131 .

[0050] Since the first battery 110 is directly connected to the mainboard 130 via the first connector 111, and the second battery 120 cannot be directly connected to the mainboard 130 due to factors such as space, but is connected to the mainboard 130 via a switching line 121, in this case, the impedance value of the power supply line between the second battery 120 and the power consumption unit 131 will be significantly larger.

[0051] The power consumption unit 131 needs pulse current power supply in the working state. If the second battery 120 continuously provides pulse current, the voltage on the power supply line will have a large fluctuation, which may easily lead to the board vibration problem.

[0052] Therefore, the present invention sets a switch control module 140 on the switching line 121 to disconnect the switching line 121 when the power consumption unit 131 is in a working state, so that the power consumption unit 131 is powered only by the first battery 110 with a smaller power supply line impedance value in the working state, avoiding large fluctuations in voltage on the power supply line of the second battery 120, thereby preventing the problem of ceramic capacitors driving the mainboard to vibrate due to large voltage fluctuations.

[0053] Since the transfer line 121 is disconnected by the switch control module 140 when the power consumption unit 131 is in working state, all the power supply required by the mainboard 130 except the power consumption unit 131 is provided by the first battery 110, which can solve the problem of board vibration noise, but at the same time, the capacity of the first battery is consumed more.

[0054] In some embodiments, when the power consumption unit 131 is in a non-working state, the switching line 121 is turned on.

[0055] When the power consumption unit 131 is in a non-operating state and does not need to provide a pulse current, the switch control module 140 can turn on the switching line 121 so that the second battery 120 can supply power to the mainboard 130 through the switching line 121 .

[0056] In some embodiments, a first onboard power supply circuit 112 and a second onboard power supply circuit 122 are provided on the mainboard 130, one end of the first onboard power supply circuit 112 is connected to the power consumption unit 131, and the other end is connected to the first connector 111, one end of the second onboard power supply circuit 122 is connected to the power consumption unit 131, and the other end is connected to the transfer circuit 121, the first onboard power supply circuit 112 and the second onboard power supply circuit 122 are converged to jointly supply power to the power consumption unit 131, wherein the first onboard power supply circuit 112, the second onboard power supply circuit 122 and the transfer circuit 121 constitute a balancing circuit between the first battery 110 and the second battery 120, and are used to perform voltage balancing on the second battery 120 and the first battery 110.

[0057] In some embodiments, the voltage balancing of the second battery 120 and the first battery 110 includes: the second battery 120 supplementing power to the first battery 110 .

[0058] Since the transfer line is disconnected, the second battery 120 cannot supply power to the mainboard 130, so all devices on the mainboard 130 are powered by the first battery 110, resulting in the first battery 110 having less power and voltage than the second battery 120. If the power difference and voltage difference between the two batteries are too large, there may be a risk of battery damage, so the balancing line can actually be used for the second battery 120 with more power to supplement the first battery 110 with less power.

[0059] It should be noted that the junction point of the first on-board power supply circuit 112 and the second on-board power supply circuit 122 may be the above-mentioned power supply point 150 .

[0060] In the previous embodiment, in order to avoid the board vibration problem caused by the large voltage fluctuation on the power supply line of the second battery 120, when the power consumption unit 131 is in the working state and needs pulse current power supply, the switch control module 140 disconnects the transfer line 121, so that the second battery 120 cannot supply power to the mainboard 130, and all power supply on the mainboard 130 is borne by the first battery 110. This situation will cause the battery capacity of the first battery 110 to decrease, and then the voltage of the first battery 110 will decrease. In this case, the voltage of the second battery 120 is higher and the voltage of the first battery 110 is lower. When the power consumption unit 131 is in the non-working state, the switch control module 140 turns on the transfer line 121. At this time, the second battery 120 and the first battery 110 can be connected through the balancing line, so that the second battery 120 supplements the first battery 110, so that the voltage of the first battery 110 is consistent with that of the second battery 120, and the capacity of the first battery 110 is increased.

[0061] Figure 3 It is a schematic structural diagram of a terminal shown according to an embodiment of the present disclosure.

[0062] As Figure 3 shown, in some embodiments, the terminal further includes: a current management chip 310, which is disposed on the power supply line 112 of the first board and is used to limit the current for the second battery 120 to charge the first battery 110 not to exceed a preset threshold.

[0063] When the power consumption unit 131 is in a non-operating state, the switch control module 140 can conduct the transfer line 121, so that the balancing line is connected, and the second battery 120 charges the first battery 110.

[0064] By the current management chip 310 disposed on the power supply line 112 of the first board, the magnitude of the charging current can be limited, avoiding damage to the first battery 110 caused by excessive current during charging.

[0065] In some embodiments, the current management chip 310 can also have the function of the switch control module 140.

[0066] Another current management chip can also be provided on the transfer line 121 of the second battery 120 to replace the switch control module 140. On the basis of realizing the original function of the switch control module 140, the ability of current management can also be taken into account.

[0067] In some embodiments, the preset threshold can be determined according to the value of the maximum charging current that the first battery 110 can receive.

[0068] For example, if the maximum charging current that the first battery 110 can receive is 0.5C, the preset threshold can be set at 0.5C.

[0069] In some embodiments, the current management chip 310 can also limit the magnitude of the charging current, so that the second battery 120 charges according to the magnitude of the charging current set by the current management chip 310.

[0070] Through the current management chip 310, during the charging process of the second battery 120 to the first battery 110, the first battery 110 is not damaged due to excessive charging current.

[0071] In some embodiments, the current management chip 310 is disposed on the power supply line 112 of the first board, and the charging line for the first battery 110 includes the power supply line 112 on the first board. Therefore, in addition to limiting the charging current during the charging process of the second battery 120 to the first battery 110, the current management chip 310 can also limit the magnitude of the charging current of the charger to the first battery 110 after the terminal is connected to the charger.

[0072] In some embodiments, the power consumption unit 131 includes a power amplifier for amplifying radio frequency signals.

[0073] As an example, the power consumption unit 131 can be a PA (Power Amplifier) for amplifying radio frequency signals.

[0074] For example, when the terminal is a communication device and making or receiving a call, the PA of the radio frequency signal is in an operating state. At this time, the PA requires a relatively large current, and the peak current can reach 1.5 A. And in one example, the PA requires a pulsed current of 217 Hz. Based on the terminal provided by the present disclosure, the switch control module 140 disconnects the transfer line 121 to avoid the second battery 120 from supplying power to the main board 130, thereby avoiding the second battery 120 from supplying power to the PA, which may cause large fluctuations in voltage with a frequency of 217 Hz and amplitude, and avoiding the problem of board vibration when the user uses the terminal to make or receive a call.

[0075] Figure 4 It is a schematic structural diagram of a terminal shown according to an embodiment of the present disclosure.

[0076] As Figure 4 shown, in some embodiments, the terminal includes a folding screen terminal, and the folding screen terminal includes a first body 410 and a second body 420. The main board 130 and the first battery 110 are disposed on the first body 410, and the second battery 120 is disposed on the second body 420.

[0077] The terminal is a folding screen terminal, and the main board 130 and the first battery 110 are disposed on the first body 410, and the second battery 120 is disposed on the second body 420. Since the first battery 110 and the main board 130 are disposed on the same body, they can be connected through the first connector 111 with a relatively small impedance. While the second battery 120 and the main board 130 are on different bodies and are connected through the transfer line 121 with a relatively large impedance.

[0078] It should be noted that the lines from the second battery 120 to the main board 130 all belong to the transfer line 121. The transfer line 121 includes a part on the second body 420, a part on the first body 410, and a part at the connection between the first body 410 and the second body 420. The switch control module 140 can be disposed at any position of the transfer line 121. Figure 4 This is only a feasible embodiment and should not cause any limitation to the present disclosure.

[0079] Figure 5 It is a schematic structural diagram of a terminal shown according to an embodiment of the present disclosure.

[0080] AsFigure 5 As shown, the terminal further includes: a sub-board 510 , which is disposed on the second body 420 , and at least a portion of the switching line 121 is located on the sub-board 510 .

[0081] In some embodiments, the space occupied by the sub-board 510 in the second body 420 is smaller than the space occupied by the mainboard 130 in the first body 410, the space occupied by the second battery 120 in the second body 420 is larger than the space occupied by the first battery 110 in the first body 410, and the capacity of the second battery 120 is larger than that of the first battery 110.

[0082] like Figure 5 As shown, since the space sizes of the first body 410 and the second body 420 are similar, and the space occupied by the main board 130 is larger than the space occupied by the sub-board 510, the space for the first battery 110 disposed on the first body 410 is limited, which is smaller than the space for the second battery 120 disposed on the second body 420. Therefore, the first battery 110 with a smaller capacity can be disposed on the first body 410, and the second battery 120 with a larger capacity can be disposed on the second body 420.

[0083] It should be noted that this embodiment only provides a possible example and does not limit the present disclosure. Figure 5 In the embodiment, if there is a second power consumption unit of a device requiring a pulse current on the sub-board 510, then in this case, the impedance value of the power supply line from the first battery 110 with a smaller capacity to the second power consumption unit is greater than Figure 5 The impedance value of the power supply line from the second battery 120 to the second power consumption unit in the embodiment of the present invention is as follows: Figure 5 A switch control module is provided in the power supply circuit of the first battery 110 shown in FIG. Figure 5 The first battery 110 supplies power to the second power consumption unit to avoid board vibration.

[0084] Therefore, the first battery 110 and the second battery 120 in the present disclosure refer more to the division of the roles of the two batteries when supplying power to the power consumption unit 130. The battery with a larger power supply line impedance is the second battery, and the battery with a smaller power supply line impedance is the first battery. It is not strictly defined based on capacity or connection with the main board and sub-board.

[0085] In some embodiments, the transfer circuit 121 includes: an on-board transfer circuit segment 1211 located on the sub-board 510 and an under-board transfer circuit segment 1212 located between the sub-board 510 and the main board 130; wherein, one end of the on-board transfer circuit segment 1211 is connected to the second battery 120 through a second connector 123, and the other end is connected to the under-board transfer circuit segment 1212.

[0086] In some embodiments, the switch control module 140 is disposed on the on-board transfer line segment 1211 .

[0087] The switch control module 140 is also disposed on the sub-board 510 .

[0088] In some embodiments, the main board 130 and the sub-board 510 are connected via a flexible printed circuit (FPC), and the under-board transfer circuit 1212 is disposed on the flexible printed circuit.

[0089] Because a portion of the switching circuit 121 is disposed on the flexible board, the impedance value of the switching circuit 121 is larger.

[0090] In some embodiments, the folding screen terminal is an up-down folding screen terminal.

[0091] Compared with the left and right folding screen terminal, the length of the folding axis of the upper and lower folding screen terminal is shorter, which makes the width of the soft board narrower. The switching line 121 is set on the soft board, which will cause the impedance value to be larger than that of the left and right folding screen terminal, and thus it is more likely to cause the board vibration problem caused by the above-mentioned pulse current power supply.

[0092] Therefore, in the application scenario of a terminal with a foldable screen, the board vibration problem is more obvious, and it is more necessary to adopt the solution proposed in the present disclosure.

[0093] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the disclosure disclosed herein.
