Description

Improved battery, nested battery and remote controller

Technical Field

The invention relates to the technical field of batteries, in particular to an improved battery, a nested battery and a remote controller.

Background

At present, the No. 5 AA and No. 7 AAA standard batteries are widely applied to various electronic products, and bring convenience for people to use the electronic products. Depending on the performance, standard batteries include disposable dry cells (e.g., zinc-manganese cells) and rechargeable batteries (e.g., nickel-metal hydride cells). The remote controller, the clock, the universal meter, the radio and other small power consumption electrical appliances mostly use disposable dry batteries with small self-discharge rate until no electricity is used, and some dry batteries can also have liquid leakage phenomenon to corrode a battery contact terminal and a circuit board. The disposal of the disposable dry battery is also easy to pollute the environment.

The rechargeable nickel-hydrogen battery is generally used in high-power consumption electric appliances due to high self-discharge rate, and has long service life when used in low-power consumption electric appliances, and the self-discharge power consumption is far greater than the use power consumption when used in a remote controller, so that the waste is serious. The rechargeable lithium battery with small self-discharge rate has the advantages of small volume, high charge-discharge cycle number, no pollution and no memory effect, but the voltage of the rechargeable lithium battery is approximately linearly reduced in the use process, and a voltage stabilizing circuit is generally required. However, most of the small power consumption electric appliances are not designed with a voltage stabilizing circuit, so that the rechargeable lithium battery is inconvenient to use. Moreover, for rechargeable batteries, charge protection and discharge protection are particularly important, and overcharge and overdischarge can damage the rechargeable batteries and affect the service life of the rechargeable batteries.

In addition, the voltage of the battery is reduced when the battery is used, and the battery is not output in a stable voltage mode. Therefore, electronic devices using these devices need to consider the factor of wide voltage operation, but after the voltage drops, the signal output is weakened, such as the distance of the remote controller decreases, the sound of the radio becomes smaller, and the like. If the discharge is excessive, some batteries may have leakage, which corrodes the battery contact terminals and circuit boards.

Compared with remote controllers, clocks, radios and other low-power-consumption electric appliances, the disposable dry battery used by the electric appliances is discarded after the electric appliances are powered off, and environmental pollution is easily caused. Although rechargeable batteries are also used at present, a special charger is needed, so that the use is inconvenient for users.

The remote controller using disposable dry battery is generally composed of a circuit board, a battery, a shell and keys. However, since the disposable dry battery is relatively thick and heavy, the battery box of small power consumption electric appliances such as a remote controller is designed to be relatively thick and heavy for matching with the battery.

Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.

As shown in fig. 1, a first modified battery embodiment includes: a battery body 11, a discharge protection circuit 12, and an output terminal; the discharge protection circuit 12 is electrically connected to the battery body 11, and controls the output of the battery body 11 through the output positive electrode and the output negative electrode of the output terminal. The discharge protection circuit 12 is used to protect the battery from over-discharge, and when the discharge protection circuit 12 detects that the voltage of the battery body 11 reaches the battery discharge protection voltage, the output is turned off, thereby preventing the battery from being damaged by over-discharge.

As shown in fig. 2, the second modified battery embodiment includes, in addition to the structure shown in fig. 1, that is, the battery body 21 and the discharge protection circuit 22, further includes: a voltage stabilizing circuit 23; the voltage stabilizing circuit 23 protects the battery to output a stable voltage, and the voltage stabilizing circuit 23 may be a voltage reducing and stabilizing circuit or a voltage increasing and stabilizing circuit. In another embodiment, the battery body 11 is a lithium battery.

As shown in fig. 3, the third modified battery embodiment includes, in addition to the structure shown in fig. 2, that is, the battery body 31, the discharge protection circuit 32, and the voltage stabilizing circuit 33: the charging interface 34 and the charging circuit 35 are electrically connected, wherein the charging interface 34 and the charging circuit 35 are electrically connected, and the charging circuit 35 is electrically connected with the battery body 31. It is understood that the battery body 31 is a rechargeable battery at this time. The embodiment combines the charging circuit and the discharge protection circuit together, so that the charging circuit and the discharge protection circuit can be fully used, the service life of the battery can be prolonged, the universality of the rechargeable battery can be enhanced, and the utilization rate of the battery can be improved. Although the charging circuit and the discharge protection circuit are designed in the electrical appliance in the prior art, the manufacturing cost of the electrical appliance is increased, the utilization rate is low, and when the electrical appliance reaches the life cycle of the electrical appliance, the charging circuit and the discharge protection circuit are still intact but can only be discarded together with the electrical appliance, so that the resource waste and the environmental pollution are caused. The improved battery can be removably placed into an electric appliance for use, and can be repeatedly used for other electric appliances when the battery, the charging circuit and the discharging protection circuit are still intact after the electric appliance reaches the life cycle of the electric appliance, so that resource waste and environmental pollution are avoided. In one embodiment, the charging interface 34 is a USB interface, providing a charging power input for the improved battery. In other embodiments, the charging interface may also be other types of interfaces, such as a cylindrical interface, a PS2 interface, and the like, as long as the charging interface can be adapted to an interface of an external power supply.

In another improved battery embodiment, the battery body is a rechargeable lithium battery, the self-discharge rate is low, the charging and discharging cycle life can be more than 500 times, and the service life of the battery is greatly prolonged.

Fig. 4 shows a schematic circuit diagram of the embodiment shown in fig. 3, and the discharge protection circuit 42 is composed of a voltage detection IC2, R2 and a field effect transistor Q2, wherein the field effect transistor Q2 is used as an electronic switch. When the voltage detection IC2 detects that the voltage of the battery body 41 is greater than the battery discharge protection voltage, the field effect transistor Q2 is conducted and normally outputs; when the voltage of the battery body 41 is lower than the battery discharge protection voltage, the field effect transistor Q2 is not turned on, thereby protecting the battery and preventing the battery from being damaged by over-discharge; the voltage stabilizing circuit 43 ensures output of a stable voltage; when the battery is protected and is not output, the charging interface 44 can be connected with an external power supply to charge the battery body 41 through the charging circuit 45, so that overcharge is avoided. When the battery body of the embodiment adopts the rechargeable lithium batteries, the effects of each rechargeable lithium battery can be fully exerted, and the use is convenient, so that the utilization rate and the utilization rate of the rechargeable lithium batteries are improved, the use amount of dry batteries and standard rechargeable batteries is reduced, the resources are saved, and the environmental pollution is reduced. In this case, the chip IC1 used in the charging circuit 45 is a lithium battery charging chip, the IC2 in the discharge protection circuit 42 is a voltage detection chip, and the chip IC3 used in the voltage regulator circuit 43 is a step-down voltage regulator chip.

In another embodiment, the chips IC1, IC2, IC3 and the electronic switch (i.e. the field effect transistor Q2 shown in fig. 3) may be integrated together, and may be implemented by using an existing integration process.

As shown in fig. 5, an embodiment of the nested battery of the present invention includes the modified battery 59 provided in the previous embodiment, and a housing 56, wherein the housing 56 is provided with a positive electrode 57 and a negative electrode 58 coupled to an output positive electrode and an output negative electrode of the modified battery 59, respectively. Another embodiment of the nested battery of the present invention comprises the improved battery provided in the third embodiment and a housing, wherein the housing is provided with an interface corresponding to a charging interface of the improved battery, in addition to a positive electrode and a negative electrode respectively coupled to an output positive electrode and an output negative electrode of the improved battery. In one embodiment, the interface is a charging interface for the improved battery.

In any of the above-described embodiments of the nested battery, the housing thereof may be set to a corresponding specification according to the battery specification requirements of the battery product to be used therewith; for example, according to the battery specification of electronic devices such as remote controllers, clocks, multimeters, radios, etc., the housing 56 is configured to have a corresponding size and appearance, such as a cylindrical shape, so as to be matched with a corresponding electronic device to be placed inside the matched electronic device. In one embodiment, the housing 56 with the nested batteries is made into the shape of a common standard battery, so that a plurality of dry batteries and common rechargeable batteries can be directly replaced to be used in different electric appliances, and the utilization rate of the electric appliances is improved; while also simplifying the circuitry of the electronic device in which the battery is used. In yet another embodiment, the housing 56 with the nested batteries is shaped to correspond to two dry cell batteries, thereby allowing direct replacement of two dry cell batteries. Of course, one skilled in the art can adapt the nested battery for use in an electronic device by adjusting the electrode position and electrode shape.

The embodiment of the invention provides a remote controller which has the same basic structure as the existing remote controller, but the used battery is the improved battery or the nested battery, and the improved battery or the nested battery can be removably placed into the remote controller. As is well known to those skilled in the art, the shape and weight of the remote controller are affected by the battery, and the conventional remote controller generally uses a cylindrical dry battery, which makes the shape of the remote controller relatively thick and the weight relatively heavy.
