However, there are still some problems with this kind of mobile terminal companion. The MICRO-USB interface, LIGHTNING interface and USBA-type interface set on the periphery of the main body cannot be effectively accommodated, and the connection cables are also entangled and pulled, which makes it difficult to separate and damage the connection cables. possible.

In view of the problem that the connecting cables may be entangled and pulled, the connecting cables of the MICRO-USB interface and the LIGHTNING interface protrude from both sides of the mobile terminal companion body, and are relatively parallel and staggered. After the connecting cables wrap around the bottom of the body along the wire slot, The interface parts are respectively inserted into the accommodating grooves corresponding to the shape of the interface on the other side of the body, and only the USBA type interface connection cables are left, so there is no situation where the connection cables are entangled and pulled. However, since the connecting wire 3 of the MICRO-USB interface and the connecting cable 4 of the LIGHTNING interface are only placed in the accommodating groove without a fixing device, the connecting cable of the MICRO-USB interface and the LIGHTNING interface may There is still a risk of the connecting cables being entangled and pulled apart from the accommodating groove. In this regard, a slot extending into the body can be provided at the end of the accommodating groove, and the metal ends of the MICRO-USB interface and the LIGHTNING interface located in the accommodating groove can be inserted into the slot, and the wire slot is close to the Limiting projections for limiting the outward movement of the connecting cable are provided on the upper and lower sides of the part that accommodates the groove. In this way, the connection cables of the MICRO-USB interface and the LIGHTNING interface are fixed in the accommodation groove, only when the MICRO-USB interface or the LIGHTNING interface is pushed out of the slot, the connection cable leaves the accommodation groove, during the carrying process There is no such risk.

In the above-mentioned mobile terminal companion, the connection cables of the MICRO-USB interface and the LIGHTNING interface are stored in the groove to avoid the problem of being entangled and pulled, but the USBA type interface connection cable 2 also has the same problem as other cables during carrying. In order to solve this problem, the connection cable of the USBA type interface protrudes from the top surface of the mobile terminal companion body, and another plug for the USBA type interface is arranged side by side at a position parallel to the top surface. Slot, an opening is arranged on the outside of the slot, and an elastic card is arranged at the position corresponding to the opening of the plastic part of the USBA type interface. The end of the elastic card near the bottom of the opening is fixedly connected with the plastic part of the USBA type interface. One end at the top of the opening protrudes obliquely outwards. The USBA-type interface is inserted into the slot and is pressed tightly by the elastic card. When using it, the USBA-type interface needs to be pressed to push the shrapnel out of the USBA-type interface. The first and last sections of the USBA-type interface connection cable 2 are fixed to avoid entanglement with other items, and A certain space is formed between the USBA type interface connection cable 2 and the main body of the mobile terminal companion, and this kind of slot is firm and reliable, and it is very convenient to insert and push out, and can be used as a lock to buckle the mobile terminal companion on the strap or waist without occupying The space inside the bag is very suitable for carrying around and can also be used as a decoration.

In addition, in order to fit the usage habits of users, the utility model can also be designed as a keychain type, as shown in FIG. 2 . The USBA-type interface is directly fixed on the top of the body, and a cap corresponding to the USBA-type interface is provided on the top of the body. The feature of this design is to cancel the connecting cable of the USBA interface, fix the USBA interface on the top of the body, and design a cap to protect the USB interface. The front end of the cap has a convex ring, which can be inserted into the key ring. When you need to use it, remove the cap to separate the mobile terminal companion from the key ring, and you can freely use various functions of the mobile terminal companion. When you don’t need to use it, put the cap on, and the mobile terminal companion is stored on the key ring. It can be carried along with the key so that it is not easy to lose. It is the same as the current portable USB flash drive on the market, and it is more suitable for the user's usage habits.

The connection cable of a mobile terminal companion with a MICRO-USB interface and a LIGHTNING interface is applicable to different types of mobile terminal equipment, but different mobile terminal equipment may have different rated power supply voltages and currents. The voltage and current powering it may affect the charging effect and service life of the mobile terminal equipment. For this reason, it is essential to set up a charging management circuit for the mobile terminal companion. The charging management circuit described here is essentially a voltage conversion circuit and a matching circuit. , in practice, since the voltage of ordinary batteries is generally lower than the charging voltage required by the mobile terminal, this kind of voltage conversion circuit is generally set as a boost circuit to ensure that the output charging voltage matches the charging voltage required by the mobile terminal equipment. ; The charging matching circuit communicates with mobile phones and other devices to recognize and accept the corresponding charging input, so as to enter the normal charging state. However, there are still some problems in keeping the charging matching circuit working for a long time. When using other functions such as the data line function, the matching voltage and current of the charging matching circuit may exist in the process of data transmission, resulting in data error transmission or even loss. Data at risk. To solve this problem, an access switch is set in the charging matching circuit to control whether the charging matching circuit works, so as to avoid the situation that the charging matching circuit still works when it is not in use.

In order to better ensure that the charging matching circuit does not need to work, the contact switch can be used as a charging matching circuit switch and set in the slot where the USBA type interface is inserted. When the slot is not inserted into the USBA type interface, the access switch is in the off state. The charging matching circuit does not work; when the USBA type interface is inserted into the slot, the access switch is closed, and the charging matching circuit works. Because when the user uses the USBA interface to connect the cable, the mobile terminal partner may be in the function of a common U disk or a data cable, and there is no need for a charging matching circuit to work at this time. Therefore, if the USB interface is not inserted into the slot, the access switch is turned off. The charging matching circuit does not work when it is not required. For the second type of mobile terminal companion structure, the charging matching circuit switch can be set in the USBA-type interface cap, and it can also detect whether the USBA-type interface is plugged in to control whether the access switch is turned on, so as to realize the above functions.

However, if the charging matching circuit switch is set in the slot where the USBA type interface is inserted, a hardware switch needs to be added, which reduces the integration of the device. For this, the control flash memory circuit originally arranged in the body can be used to connect or disconnect the interface. toggle switch. As shown in FIG. 3 , the switching switch is provided with an intelligent electronic switch, which is divided into three gears, gear A connected to the charging matching circuit, gear B suspended and gear C connected to the flash memory circuit. When the electronic switch is in the position A of the charging matching circuit, the charging matching circuit is connected to work, so that the output charging voltage matches the charging voltage required by the mobile terminal to ensure charging safety; when the electronic switch is in the floating position B, the charging The equipped circuit and the flash memory circuit are not connected. The USBA interface and the MICRO-USB interface and the LIGHTNING interface respectively form two paths through the connecting cable. Take out the USBA interface and any other interface connected to it through the connecting cable. Constitute a data line to realize the hub function of the mobile terminal companion; when the electronic switch is in the access position C of the flash memory circuit, the flash memory circuit is connected to the MICRO-USB interface, the LIGHTNING interface and the USBA interface through the connecting cable, because the USBA type The interface is an ordinary USB male interface, so take out the corresponding interface and connect it to the terminal device to realize the function of an OTG mobile phone U disk or an ordinary U disk. This kind of switch setting method realizes the function of the charging matching circuit switch at the same time by using the original switching switch, omitting a hardware switch, making the electronic integration of the mobile terminal companion higher, and also avoiding the possibility of using two hardware switches. The possibility of simultaneously connecting the flash memory circuit and the charging matching circuit makes the mobile terminal more convenient and reliable to use.

As shown in Figure 4, a battery compartment is provided in the main body of the mobile terminal companion, and a limiting groove corresponding to one end of the battery is provided on the main body base 7 for 6 battery ends to be inserted into, and in the limiting groove 6 The bottom is provided with an elastic electrode sheet in contact with the electrode of the loaded battery, and the main body cover plate 5 is provided with an electrode sheet in contact with the electrode at the other end of the loaded battery; between the base 7 and the cover plate 5, between the loaded battery The positions on both sides are provided with drawstrings, and the drawstrings can compress the loaded batteries between the cover plate and the bottom plate. This kind of battery compartment structure can load the battery when the battery is needed, but it can be stored when the battery is not needed. It is different from the original design method that needs to preset the battery placement position. When unfolded, it can be stored and placed in most of the idle time, so that the mobile terminal companion described in the utility model is more portable and compact, and is convenient to carry. At the same time, the design scheme of using ordinary batteries to power mobile terminal equipment is also different from traditional charging treasures, which has significant advantages. This kind of mobile terminal companion does not need to be charged, and there is no situation of complete power consumption. It can be realized by using convenient and easy-to-get ordinary batteries. The power supply of mobile terminal equipment, in daily life, ordinary batteries are convenient and easy to get, and there is no risk of power failure when you buy and charge, avoiding the embarrassing situation of no power when using traditional charging treasures, but in the face of lack of mains power or disasters In the special case of a power outage, this emergency power supply function can also provide reliable power supply protection for mobile terminal equipment, ensuring that the user's important communication is not lost. Compared with traditional charging treasures, it is lighter, more portable, more functional, and its own integrated connection The advantage that the cable does not need to be used with other accessories.

At the same time, in order to meet the needs of users who are accustomed to using data lines, the utility model can also be designed as a data line type, as shown in FIG. 5 . This design cancels the design of two connecting cables used in the MICRO-USB interface and the LIGHTNING interface. This mobile terminal companion includes a main body, which is equipped with a flash memory circuit, and a USBA type interface and a MICRO- The USB interface and the flash memory circuit are respectively connected to the above two interfaces through the connection cable, and the connection switch is provided on the connection cable to connect or disconnect the control interface and the flash memory circuit; the USBA type interface is connected to the MICRO-USB interface; There is a battery compartment, which is equipped with two electrode sheets corresponding to the positive and negative poles of the loaded battery to lead out its electrodes.
