Description

Technical Field

[0001] The invention belongs to the field of wireless communication receiving terminal equipment manufacturing. Background Art

[0002] The known mobile phone working system (hereinafter referred to as mobile phone system) is powered by the battery in the mobile phone (hereinafter referred to as battery). When the battery is low, an external power source is used to charge the battery. As the number of charging times increases, the battery performance decreases, and frequent charging will accelerate battery aging and low power, causing automatic shutdown. At this time, even if an external power source is connected, the mobile phone system cannot be turned on and used.

[0003] New solid-state batteries are expensive to manufacture and are not widely available. Experts suggest that reducing the use of mobile phones can extend the battery life, but this contradicts the needs of users. Summary of the invention

[0004] The present invention provides a solution to the problem: an independent power supply system is added to the mobile phone, and when the mobile phone system is powered by an external power supply, the battery is not charged, while the original charging system is retained to charge the battery.

[0005] The technical solution adopted by the present invention to solve the technical problem is: under the premise of retaining the original battery charging system, the power supply circuit inside the machine is changed, so that the mobile phone system is directly connected to the added external power socket electrode, and necessary sockets, switches (mechanical, chip type), etc. are added to form an independent external power supply system. When the added external power supply is connected, the switch cuts off the original power supply circuit from the battery to the mobile phone system; when the added external power supply is disconnected, the switch connects the original power supply circuit from the battery to the mobile phone system. The power supply system can make the external power supply not charge the battery when supplying power to the mobile phone system, reduce the number of battery charging times, and extend the battery life. Even if the mobile phone is shut down due to battery aging or insufficient power, the mobile phone can be turned on and used with an external power supply. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 5 This is a schematic diagram of the line connection after a switch is installed on the original power supply line.

[0013] Specific implementation plan 1:

[0014] An independent external power round hole socket 1 is added to the mobile phone, and the positive and negative poles of the socket 1 are connected to the positive and negative poles of the power supply line of the mobile phone system 6, and the power supply line of the mobile phone system 6 and the mobile phone battery 7 are disconnected at the same time. A transistor or integrated circuit chip 8 (hereinafter referred to as the switch chip) capable of switching current is added between the disconnected lines, and the positive and negative poles of one end of the switch chip 8 are connected to the positive and negative poles of the power supply line of the mobile phone system 6, and the positive and negative poles of the other end are connected to the positive and negative poles of the power supply line of the mobile phone battery 7. The trigger electrode line 4 of the switch chip 8 is connected to one side electrode of a contact type mechanical switch (hereinafter referred to as the mechanical switch) 5 next to the external power socket 1, and the other side of the mechanical switch 5 is an electrode with weak electricity, and the weak electricity can trigger the chip switch.

[0015] Open an opening on the side of the socket 1, and fix the mechanical switch 5 on the side of the opening of the socket 1, so that when the electrode spring sheet of the socket 1 is displaced, it can touch the electrode of the weak-current spring sheet of the mechanical switch 5 (if it cannot reach the position, a plastic slider can be added). The mechanical switch 5 remains in the normally closed state, at which time the switch chip 8 is turned on, and the battery 7 supplies power to the mobile phone system 6. Figure 1 .

[0016] When the independent external power circular plug 2 is inserted into the socket 1, the external power starts to supply power to the mobile phone system 6. At the same time, the top of the plug 2 causes the electrode spring piece in the socket 1 to be displaced and is stuck in the groove at the top of the plug 2 for positioning. When the electrode spring piece in the socket 1 moves, it drives the electrode of the trigger line of the adjacent mechanical switch 5 to be displaced (if it cannot be reached, a plastic slider can be added), so that the mechanical switch 5 is disconnected, and the chip switch 8 is disconnected after losing the weak current control, cutting off the power supply line of the battery 7 to the mobile phone system 6; when the independent external power circular plug 2 is unplugged from the socket 1, the external power stops supplying power. When the top of the plug 2 is unplugged, the electrode spring piece in the socket 1 is displaced again, and the weak current electrode spring piece of the adjacent mechanical switch 5 is displaced again (if it cannot be reached, a plastic slider can be added), so that the mechanical switch 5 is closed, and the switch chip 8 is turned on after obtaining the weak current control, connecting the power supply line of the battery 7 to the mobile phone system 6.

[0017] Solution 1 uses an external power plug 2 to trigger a switch chip 8 to control the power supply line of a mobile phone battery 7, thereby avoiding the poor contact phenomenon that may occur when a mechanical switch is used to control a large current.

[0018] Specific implementation plan 2:

[0019] An independent external power supply round hole socket 1 is installed in the mobile phone, and the positive and negative poles of the socket 1 are connected to the positive and negative poles of the power supply line of the mobile phone system 6, and the power supply line of the mobile phone system 6 and the mobile phone battery 7 are disconnected. An electrode contact type mechanical switch 5 is installed between the disconnected lines, and the positive and negative poles of one end of the mechanical switch 5 are connected to the positive and negative poles of the power supply line of the mobile phone system 6, and the positive and negative poles of the other end are connected to the positive and negative poles of the power supply line of the mobile phone battery 7. The mechanical switch 5 is fixed on the opening side of the external power supply socket 1, and the mechanical switch 5 is kept in a normally closed state. At this time, the mechanical switch 5 is turned on, and the battery 7 supplies power to the mobile phone system 6. Figure 2 .

[0020] When the independent external power round plug 2 is inserted into the socket 1, the external power starts to supply power to the mobile phone system 6. At the same time, the top of the plug 2 causes the electrode spring piece in the socket 1 to move and clamp the groove at the top of the plug 2 to position. When the electrode spring piece in the socket 1 moves, it drives the electrode piece on one side of the mechanical switch 5 next to it to move (if it cannot reach the position, a plastic slider can be added), so that the mechanical switch 5 is disconnected, and the power supply line of the battery 7 to the mobile phone system 6 is cut off;

[0021] When the independent external power round plug 2 is pulled out of the socket 1, the external power supply stops supplying power. When the top end of the plug 2 is pulled out, the electrode spring piece in the socket 1 is displaced, which again drives the electrode spring piece on one side of the mechanical switch 5 to be displaced (if it cannot reach the position, a plastic slider can be added), so that the mechanical switch 5 is closed, connecting the power supply line of the battery 7 to the mobile phone system 6.

[0022] Solution 2 uses a mechanical switch to disconnect the power supply line of the mobile phone battery, which is simple and easy.

[0023] Specific implementation plan three:

[0024] An independent external power rectangular hole socket 1 is installed in the mobile phone, and the positive and negative lines of the socket 1 are connected to the positive and negative lines of the mobile phone system 6 power supply line, and the power supply line of the mobile phone system 6 and the mobile phone battery 7 are disconnected at the same time. An electrode contact type mechanical switch 5 is installed between the disconnected lines, and the positive and negative poles of one end of the mechanical switch 5 are connected to the positive and negative poles of the power supply line of the mobile phone chip system 6, and the positive and negative poles of the other end are connected to the positive and negative poles of the power supply line of the mobile phone battery 7. The mechanical switch 5 is fixed on the opening side of the external power socket 1, and the mechanical switch 5 is kept in a normally closed state. At this time, the switch 5 is turned on, and the battery 7 supplies power to the mobile phone system 6. Figure 3 .

[0025] When the independent external power rectangular plug 2 is inserted into the socket 1, the external power starts to supply power to the mobile phone chip system 6. At the same time, the top of the plug 2 causes the plastic slider installed inside the opening of the socket 1 to move, driving the electrode sheet on one side of the mechanical switch 5 to move, causing the mechanical switch 5 to be disconnected, thus cutting off the power supply line from the battery 7 to the mobile phone system 6.

[0026] When the independent external power rectangular plug 2 is unplugged from the socket 1, the external power stops supplying power, and when the top of the plug 2 is unplugged, the added plastic slider is displaced, which again drives the electrode spring sheet on one side of the mechanical switch 5 to displace, so that the mechanical switch 5 is closed, connecting the battery 7 to the power supply line of the mobile phone system 6.

[0027] Solution three uses a mechanical switch to disconnect the power supply line of the mobile phone battery. It is simple and easy to use, and uses a rectangular plug to cater to the trend.

[0028] Specific implementation plan four:

[0029] Install a sliding switch 9 (or a flip-type double-throw switch 12, a push-push double-throw switch 13) on the side or bottom of the mobile phone to disconnect the original battery from the power supply circuit of the mobile phone system, and connect the two disconnected ends to the two end electrodes of the circuit board 11 of the sliding switch 9 (or the two end electrodes of the flip-type double-throw mechanical switch 12, the push-push double-throw mechanical switch 13); connect or keep the power supply circuit of the original external power socket connected to the power supply circuit of the mobile phone system 6, and connect the external power supply to the original charging port of the mobile phone. When the sliding switch 9 (or the flip switch 12, the push-push switch 13) is used to cut off the original battery power supply circuit, the external power supply only supplies power to the mobile phone system and does not charge the battery; when the sliding switch 9 (or the flip switch 12, the push-push switch 13) is used to connect the original battery power supply circuit, the external power supply supplies power to the mobile phone system 6 and also charges the battery 7. See Figure 4 , Figure 5 .

[0030] This method is simple and easy to use, but if you forget to reset the switch, the phone may shut down due to disconnection from the internal and external power supply, and you need to restart it. To avoid power failure and shutdown, the slide switch 9 can be installed next to the power socket at the bottom of the phone, so that when the slide switch handle 10 moves toward the power socket, the battery will be cut off from supplying power to the phone system (that is, the slide switch handle 10 moves to the Figure 5 The upper end of the circuit board 11), and then install a positioning card (or positioning bolt, pin, needle) 10-2 at the position of the sliding switch handle 10 inside the mobile phone, and open a positioning hole or positioning groove 15-2 on the mobile phone plug 15-1. In this way, when the original power socket is inserted into the external power rectangular plug 15, the handle 10 of the sliding mechanical switch 9 can lock the power rectangular plug 15. Only when the handle 10 of the sliding mechanical switch 9 pulls out the positioning card or positioning bolt 10-2 and connects the battery to the power supply line of the mobile phone system, the external power rectangular plug 15 can be pulled out of the original power socket, thereby avoiding the power failure and shutdown phenomenon. Figure 5 , Figure 6 .

[0031] Solution 4 only requires the installation of a mechanical switch and the change of the battery power supply circuit. The original charging plug can still be used or the plug can be slightly changed. No additional socket is required, which is simple and easy.

[0032] Specific implementation plan five:

[0033] When the original chip function of the mobile phone is allowed, the rich functions of the original chip of the mobile phone are used to replace the added chip switch 8, and the following instruction program code is added: check whether the added external power socket is powered, if yes, disconnect the battery power supply and charging line; if not, connect the battery power supply and charging line. At this time, only the external power socket 1 and the mechanical switch 5 need to be added, and the power supply line of the external power socket is connected to the mobile phone system 6, the line from the battery to the mobile phone system is disconnected, and the disconnection point is connected to the relevant electrodes of the original chip of the mobile phone. The form of the added socket 1 is as described in the previous scheme 1, and will not be repeated. See attached Figure 1 .

[0034] It should be noted that in all the above schemes, whether a new or existing external power source is used, the plug must be connected to a suitable power adapter or an external battery port with a voltage limiter and current limiter through a power cord; if powered by a battery, the battery can be placed in a special protective bag 14 made of a composite of high-strength fiber fabric and shock-absorbing material, and the protective bag can be put into a backpack, pocket or hung around the waist for safety. Figure 3 .

[0035] The beneficial effects of the present invention are:

[0036] The mobile phone can be turned on and used with an external power supply, which reduces the power supply of the mobile phone battery and meets the needs of long-term use of the mobile phone; postpones the replacement of the mobile phone battery to save costs; avoids the risk of shutdown due to insufficient or aging mobile phone battery. It is especially suitable for participating in telephone conferences, telephone lectures, playing mobile games, traveling, field operations, and using mobile phones in wartime environments.

[0037] The invention is simple and feasible, and is conducive to promotion and increasing market competitiveness.
