CN201639635U - Mobile phone maintaining communication during replacement of cell - Google Patents

Abstract

The utility model claims a mobile phone maintaining communication during replacement of a cell, belonging to the electricity field. The mobile phone comprises a shell, a chip mounted in the shell and a mobile phone cell supplying power for the chip. The improvement is that the chip is additionally connected with an auxiliary power circuit connected with a chip power in parallel; the auxiliary power circuit is formed by connecting an auxiliary cell and a power switch in series; and the power switch is a manual control switch or a triggering switch. The auxiliary cell is switched on through the power switch when the mobile phone cell is replaced, thereby ensuring that the mobile phone cell can be replaced under the condition of uninterrupted communication, simplifying the complicated operation for shutting down and starting up when the mobile phone cell is replaced, and bringing convenience for a user on replacing the mobile phone cell under the communication state when the power is used up during a call.

Description

A kind of mobile phone of also keeping in communication when changing battery

Technical field:

The utility model belongs to electricity field, a kind of specifically mobile phone of also keeping in communication when changing battery.

Figure viewed from behind technology:

Development along with wireless telecommunications, mobile phone is because easy to carry, realized mobile communication, gradually the position that has replaced landline telephone, the communication tool that often uses when becoming the daily contact of people, but mobile phone is subjected to the restriction of battery of mobile phone capacity, communication time is limited, when the battery of mobile phone electric energy exhausts, have only the standby battery of mobile phone of replacing could continue to use, when changing battery of mobile phone, must under the situation of mobile phone outage, just can finish the operation of changing battery of mobile phone in the shutdown back, start is again operated and is not only loaded down with trivial detailsly said, if the situation that the battery of mobile phone electric energy will exhaust occurs in communication process after the replacing, change battery of mobile phone and will have influence on the caller this moment, caused inconvenience for the people who is using.

Summary of the invention:

The purpose of this utility model just provides a kind of mobile phone of also keeping in communication when changing battery, and it can keep the communication state of mobile phone in the process of changing battery of mobile phone, makes people finish the operation of changing battery of mobile phone in the process of uninterrupted communication.

The utility model comprises casing, be contained in the movement in the casing, battery of mobile phone for the movement power supply, the improvement of being done is that an auxiliary power circuit is installed on movement again, the power supply formation of auxiliary power circuit and movement is connected in parallel, auxiliary power circuit is to be connected in series by a boosting battery and a mains switch to constitute, and mains switch can be mounted in the hand control switch of casing side; Also can be trigger switch, trigger switch can be selected the trigger switch of normally-closed contact, trigger switch is arranged on the position that can trigger after bonnet on the fuselage is installed, like this, when installing bonnet, trigger switch is triggered, the contact disconnects, and boosting battery is in off state; When unloading bonnet, trigger switch resets, the closing of contact, and boosting battery is in conducting state, for the movement power supply, more than is basic design of the present utility model.

Good effect of the present utility model is: can finish the replacing of battery under the situation that keeps the mobile phone operate as normal, simplified when changing battery of mobile phone needs shutdown earlier, these troublesome operation of start again to mobile phone in the past, has solved to run into to change battery of mobile phone when occurring situation that electric energy will exhaust in the communication process and bring just to the user.

Specific embodiment:

Electrical principle is as shown in Figure 1: boosting battery 1 connects into auxiliary power circuit I with boosting battery 2; Battery of mobile phone 3 is as the movement power supply, concrete structure is as shown in Figure 2: the battery compartment 4 that leaves a boosting battery on the casing of mobile phone, the both positive and negative polarity of corresponding boosting battery is provided with two electric contacts 5 in the battery compartment 4, two electric contacts 5 of boosting battery connect with the corresponding both positive and negative polarity of two electric contacts of battery of mobile phone, boosting battery and battery of mobile phone are constituted to be connected in parallel, mains switch of connection is set between the electric contact of two positive poles, promptly finishes of the present utility model being electrically connected; Mains switch can be selected two kinds of modes: a kind of mode is the manual mode that is connected control with the hand control switch 6 that is positioned at the fuselage side; Another kind be be positioned at fuselage on the position that can trigger after installing of bonnet 7 trigger switch 8 installed is connected the triggering mode of controlling, trigger switch can be selected normally-closed contact; A kind of cutaway view of trigger switch as shown in Figure 3, the insulation shell 9 that comprises column, place the back-moving spring 10 in the insulation shell 9, be positioned at the contact that presses that contact 11 is installed on the back-moving spring 10, with insulation shell 9 integrant contacts 12, wherein pressing contact makes with insulating material, pressing contact is made of the thin thick contact 14 in depression bar 13 connection lower ends in upper end, depression bar 13 can pass from the hole on 12 surfaces, contact, pressing contact 14 can move up and down in the space of insulation shell 9 and contact 12 formations, under the effect of back-moving spring 10, the be electrically connected to form normally-closed contact of trigger switch of contact 11 and contact 12, when installing bonnet, bonnet presses depression bar 13, make depression bar 13 depress contact 14 and move down, contact 11 disconnects with contact 12.

Boosting battery can be determined the voltage and the capacity of boosting battery according to the voltage of battery of mobile phone, the voltage of general most batteries of mobile phone is 3.7V, so can select voltage is 3.5V-3.7V, the dc-battery of capacity between 100mAh-150mAh is as boosting battery.

Claims (2)

1. mobile phone of also keeping in communication when changing battery, comprise casing, be contained in the movement in the casing, battery of mobile phone for the movement power supply, it is characterized in that described movement is connected with an auxiliary power circuit that is connected in parallel with the movement power supply, auxiliary power circuit is connected in series by boosting battery and mains switch and constitutes, and mains switch is hand control switch or trigger switch.
