All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.
The embodiment of the invention provides a power supply system of intelligent glasses. Fig. 1 is a schematic structural diagram of a power supply system of smart glasses according to an embodiment of the present invention. Referring to fig. 1, the power supply system of the smart glasses includes: a first battery module 10, a first control module 20, a second battery module 30, and a second control module 40.
The output end 11 of the first battery module 10 is electrically connected with the input end 21 of the first control module 20; the output terminal 31 of the second battery module 30 is electrically connected with the input terminal 41 of the second control module 40; the connection 22 of the first control module 20 is electrically connected to the connection 42 of the second control module 40. The power supply output end VD of the power supply system is led out from the connection end 42 of the second control module 40. The first control module 20 is configured to control whether the first battery module 10 transmits electric energy to the power supply output terminal VD according to the output voltage of the output terminal 11 of the first battery module 10 and the voltage of the power supply output terminal VD; the second control module 40 is configured to control whether the second battery module 30 transmits electric energy to the power supply output terminal VD according to the output voltage of the output terminal 31 of the second battery module 30 and the voltage of the power supply output terminal VD.
In the present embodiment, the power supply branch of the first battery module 10 and the first control module 20 and the power supply branch of the second battery module 30 and the second control module 40 are equivalently connected in parallel. Therefore, any power supply branch is out of operation, external power supply of the power supply system is not affected, and a foundation is provided for online replacement of the battery module.
Referring to fig. 1, the power supply process of the power supply system is exemplarily as follows: the first control module 20 controls whether the first battery module 10 is conducted with the power supply output end VD according to a voltage difference between the output voltage of the first battery module 10 and the voltage of the power supply output end VD; the second control module 40 controls whether the second battery module 30 is connected to the power supply output terminal VD according to a voltage difference between the output voltage of the second battery module 30 and the voltage of the power supply output terminal VD. The control principles of the two control modules are basically the same, and the control principles are as follows: when the voltage difference obtained by subtracting the voltage of the power supply output end VD from the output voltage of the battery module is larger than the conduction threshold value of the control module, the control module controls the battery module to be communicated with the power supply output end VD; when the voltage difference obtained by subtracting the output voltage of the battery module from the voltage of the power supply output end VD is larger than the turn-off threshold value of the control module, the control module controls the battery module not to be communicated with the power supply output end VD. When both battery modules are connected to the system, the two control modules automatically control the power supply path in the system according to the principle.
Illustratively, when the output voltage of the first battery module 10 is the same as the output voltage of the second battery module 30, the first control module 20 and the second control module 40 control the first battery module 10 and the second battery module 30 to simultaneously supply power to the power loads in the smart glasses. When the voltage difference between the output voltages of the two battery modules is large, the voltage of the power supply output end VD is approximately equal to the output voltage of the high-voltage battery module. Then, the control module corresponding to the low-voltage battery module temporarily controls the disconnection of the path between the low-voltage battery module and the power supply output terminal VD. Namely, at the moment, the system preferentially enables the high-voltage battery module to work, the two control modules automatically select the battery modules in the working state according to the voltage of the power supply output end VD and the voltage difference between the output ends of the two battery modules respectively until the output voltages of the two battery modules are equivalent, and the two battery modules simultaneously supply power to the load in the intelligent glasses.
When the power supply system is insufficient in electric quantity and the battery needs to be disassembled and replaced, one battery module can be selected to be disassembled and replaced, and then the other battery module is disassembled and replaced after the disassembly and replacement are completed. Like this, can guarantee to tear the in-process open at the battery and trade, have a power supply branch road in the work among the power supply system all the time, promptly, can realize the battery change under intelligent glasses running state, effectively improve the duration of intelligent glasses. The battery replacing process can be to only replace the battery in the battery module, or to replace the whole battery module. That is, the battery module may be fixedly connected with the smart glasses, only the battery may be detachable, or the battery module itself may be detachably connected with the smart glasses main body.
For example, taking the replacing process of the first battery module 10 as an example, when the first battery module 10 is powered off and quits working, the second control module 40 controls the second battery module 30 to be kept in conduction with the power supply output end VD, and the second battery module 30 supplies power. At the moment, the intelligent glasses can be in a power-off state or an operating state and can be selected according to actual conditions. When the first battery module 10 is replaced by a high-power battery module after the replacement is completed, the two control modules can automatically select the battery module in the working state again according to the voltage of the power supply output end VD and the pressure difference between the output ends of the two battery modules, and the intelligent glasses continue to work normally. Similarly, when the second battery module 30 is detached and replaced, the first battery module 10 may transmit electric energy to the power supply output end VD through the first control module 20, so as to ensure normal operation of the smart glasses.
It should be noted that the present embodiment does not limit the order of replacing the two battery modules. In the process of replacing any battery module, the control module can control the other battery module to be kept in a working state and transmit electric energy to the power supply output end VD, so that the load of the intelligent glasses can obtain the electric energy from the power supply system all the time, and the normal working state is maintained.
Illustratively, when the electric quantity of at least one battery module in the power supply system is lower than the warning threshold value, the intelligent glasses can remind the user to in time tear down the battery module and trade.
The power supply system of the smart glasses provided by the embodiment of the present invention is provided with a first battery module 10, a first control module 20, a second battery module 30, and a second control module 40. The first battery module 10 and the first control module 20 form one power supply branch, and the second battery module 30 and the second control module 40 form the other power supply branch. And relative to the power supply output end VD, the two power supply branches are connected in parallel. Therefore, the normal output of the power supply system is not influenced when any power supply branch is powered off. And the two control modules are arranged, so that in the dismounting and replacing process of any battery module, the other battery module can be kept in a working state under the control of the control module, electric energy is transmitted to the power supply output end VD, the intelligent glasses are ensured to maintain normal work in the battery dismounting and replacing process, and the cruising ability of the intelligent glasses is improved. Simultaneously, the user only need carry battery or battery module spare, need not to carry charging wire and portable power source equipment, also need not to use intelligent glasses under the state of connecting the charging wire to guarantee intelligent glasses's practicality. Therefore, compared with the prior art, the embodiment of the invention can improve the cruising ability of the intelligent glasses on the basis of ensuring the practicability.
Fig. 1 shows an exemplary supply output VD from a connection 42 of the second control module 40, without limiting the invention. In other embodiments, the power supply output terminal VD of the power supply system of the smart glasses may also be led out from the connection terminal 22 of the first control module 20; or, a power supply output terminal VD is respectively led out from the connection end 22 of the first control module 20 and the connection end 42 of the second control module 40, and the power supply output terminals respectively supply power to different loads of the smart glasses, and the power supply principle is similar to the above principle, and is not described again. For example, as shown in fig. 2, the power supply output end led out from the connection end of the first control module 20 supplies power to the load 60 closer to the first control module 20, and the power supply output end led out from the connection end of the second control module 40 supplies power to the load 60 closer to the second control module 40, so as to simplify the wiring inside the smart glasses.
For example, the different loads may be a display component of the smart glasses, SoC, speaker, camera, etc., respectively.
Fig. 2 is a schematic structural diagram of another power supply system for smart glasses according to an embodiment of the present invention. Referring to fig. 2, on the basis of the above embodiments, the connection end of the first control module 20 and the connection end of the second control module 40 are optionally connected by a connection cable. This connection cable is labeled as connection module 50 in fig. 2. When the power supply system works and the power supply output end VD supplies a system power supply signal to the outside, the connection module 50 basically does not consume electric energy, the voltages at the two ends are basically the same, and the judgment and the work of the two control modules are not influenced. Specifically, the connection module 50 may be formed by a cable (cable) or a Flexible Printed Circuit (FPC) cable, and may be specifically selected according to actual requirements.
With continued reference to fig. 2, based on the above embodiments, optionally, the first battery module 10 includes: the negative pole of the first battery 110 is grounded, and the positive pole of the first battery 110 is electrically connected with the input end of the first control module 20. The first battery 110 may be a lithium ion battery or a lithium polymer battery. The first battery 110 may be a single battery or a battery pack formed by connecting a plurality of batteries in series.
The second battery module 30 includes: and a second battery 310, wherein the negative pole of the second battery 310 is grounded, and the positive pole of the second battery 310 is electrically connected with the input end of the second control module 40. The second battery 310 may be a lithium ion battery or a lithium polymer battery. The second battery 310 may be a single battery or a battery pack formed by connecting a plurality of batteries in series.
With continued reference to fig. 2, based on the above embodiments, optionally, the first control module 20 includes: a first ideal diode circuit 210, a first terminal of the first ideal diode circuit 210 is electrically connected to the input terminal of the first control module 20, and a second terminal of the first ideal diode circuit 210 is electrically connected to the connection terminal of the first control module 20. The first ideal diode circuit 210 has a characteristic of unidirectional conduction, and illustratively, the first end of the first ideal diode circuit 210 is an equivalent anode thereof, and the second end of the first ideal diode circuit 210 is an equivalent cathode thereof, so as to realize a main function of the first control module 20, that is, whether the first battery module 10 is communicated with the power supply output end VD is controlled by the output voltage of the first battery module 10 and the voltage of the power supply output end VD.
The second control module 40 includes: and a second ideal diode circuit 410, wherein a first terminal of the second ideal diode circuit 410 is electrically connected with the input terminal of the second control module 40, and a second terminal of the second ideal diode circuit 410 is electrically connected with the connection terminal of the second control module 40. The operation of the second ideal diode circuit 410 can be referred to the explanation of the first ideal diode circuit 210, and will not be described in detail.
Fig. 3 is a schematic structural diagram of a power supply system of another smart glasses according to an embodiment of the present invention. Referring to fig. 3, on the basis of the above embodiments, optionally, the first ideal diode circuit 210 includes: a first control chip U1 and a first transistor M1; an input end VIN1 of the first control chip U1 is electrically connected to a first pole of the first transistor M1 and an input end of the first control module 20, and is connected to a first power signal provided by the first battery 110; the voltage sensing terminal SENSE1 of the first control chip U1 is electrically connected with the second pole of the first transistor M1 and the connection terminal of the first control module 20 respectively; the driving output terminal GATE1 of the first control chip U1 is electrically connected to the GATE of the first transistor M1. In fig. 3, the power supply output terminal is led out from the connection terminal of the first control module 20, and is used for providing a system power supply signal Vsys to a system circuit (load) in the smart glasses connected in the rear.
Illustratively, the first control chip U1 may be an ADI control chip LTC4412, and the first transistor M1 may be a PMOS transistor, so that the first ideal diode circuit 210 has a unidirectional turn-on characteristic. Compared with a conventional schottky diode (the conduction voltage drop is greater than 400mV), the conduction voltage drop of the first ideal diode circuit 210 is very low and is only about 20mV, so that the energy consumption of the first control module 20 can be effectively reduced, and the heating phenomenon of a power supply system is reduced.
