Utility model content
The technical problems to be solved in the utility model is to provide a kind of MIFI equipment with the precious function of charging that external charging can be provided.
The technical solution adopted in the utility model is as follows: a kind of MIFI equipment with the precious function of charging, comprise MIFI module and charging module, it is characterized in that: also comprise battery module and the discharge module that boosts, after described MIFI module, charging module and the discharge module parallel connection of boosting, be connected with battery module.
As the utility model is further improved, described battery module operating voltage is 3.3V-4.2V.
As the utility model is further improved, described in the discharge module that boosts be 5V voltage follower circuit module.
As the utility model is further improved, described battery module comprises overcharge protection circuit.
As the utility model is further improved, described battery module comprises over-discharge protection circuit.
As the utility model is further improved, described battery module comprises short-circuit protection circuit.
As the utility model is further improved, described charging module comprises current-limiting protection circuit.
As the utility model is further improved, described charging module comprises trickle charge, constant current charge and three kinds of charging circuit settings of constant voltage charge.
As the utility model is further improved, described in the discharge module that boosts comprise current-limiting protection circuit.
As the utility model is further improved, described in the discharge module that boosts comprise short-circuit protection circuit.
Compared with prior art; the beneficial effects of the utility model are: the utility model is on the basis of MIFI equipment; increase charging module 3, boost/discharge module 4 and high capacity cell module 1; and be equipped with complete charge protection, battery protection, discharge protection circuit; realize the one of high security with the precious function MIFI equipment of charging; increasing on the basis of very low cost, greatly expanding the application scenarios of MIFI equipment, greatly promoting user and experience.Ye Hui company's new product increase of the present invention attraction, postpones the MIFI device standby time, fills up market demand blank, expands company's produce market share.
Accompanying drawing explanation
Fig. 1 is the utility model theory diagram.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.That is,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of MIFI equipment with the precious function of charging, comprises MIFI module 2 and charging module 3, also comprises battery module 1 and the discharge module 4 that boosts, and after described MIFI module 2, charging module 3 and discharge module 4 parallel connections of boosting, is connected with battery module 1.
Described battery module 1 operating voltage is 3.3V-4.2V.
In this specific embodiment, battery module 1 comprises high capacity cell more than 3000mAh capacity, supports lithium ion and lithium polymer battery, battery operated voltage at 3.3V between 4.2V.Under charging module charge mode, when cell voltage is more than or equal to 3.3V, MIFI module 2 is powered by battery module 1 or charging module 3, and charging module 3 is responsible for battery module 1 to charge; Cell voltage is during lower than 3.3V, and charging module 3 is that battery module 1 charges when directly powering for MIFI module 2, and after cell voltage is charged to 4.2V, charging module 3 stops charging to battery module 1.Under charging module non-charging mode, when cell voltage is greater than 3.3V, battery module 1, when powering to MIFI module 2, can also outwards provide direct current by the discharge module that boosts, can or directly give mobile power supply equipment to the charging of mobile device battery, realize the precious function of charging.
The described discharge module 4 that boosts is for 5V voltage follower circuit module.In this specific embodiment, the discharge module that boosts outwards provides 5V direct current, can or directly give mobile power supply equipment to the charging of mobile device battery, realizes the precious function of charging.
In this specific embodiment, MIFI module 2 can receive the power supply source of 3.3V to 5V, for only supporting the battery powered MIFI module 2 of 3.3V to 4.2V, the utility model also can be used, because charging module 3 stops charging when detecting that battery terminal voltage reaches 4.2V, the voltage that therefore arrives MIFI module 2 can not exceed 4.2V.
Because the operating voltage of battery module 1 is at 3.3V to 4.2V, therefore must could provide 5V DC power supply to outside mobile device through the discharge module 4 that boosts, the effect of the discharge module 4 that boosts is for stablizing 5V direct voltage output by 3.3V to the 4.2V power conversion of battery output.In this specific embodiment, current limliting and short-circuit protection function are also provided simultaneously, otherwise run into bad mobile device, will cause this equipment impaired.
In this specific embodiment, charging module 3, according to the voltage of battery, provides trickle charge, constant current charge and three kinds of charging modes of constant voltage charge, protects to greatest extent battery, extending battery life.
Owing to mainly adopting at present lithium ion and lithium polymer battery, battery module 1 also needs to possess over-charge protective, Cross prevention, overcurrent/short-circuit protection circuit in this concrete enforcement, increase device security.
