Currently, computers are occupying an increasingly important position in people's daily life, which is mainly embodied in two major types: desktop and notebook computers. For desktop computers, a floppy disk drive is arranged on a computer case in the past to facilitate a user to copy files back and forth by using a floppy disk, but with the advent of a U-disk, the USB interface is far more used than the floppy disk drive, so that the image of a floppy drive is difficult to see again in the input and output devices of the computer. Also, for notebook computers, with the rapid development of internet technology and the use of mobile hard disks, various software and technical data can be downloaded via networks. Thus, the optical disc drive, which is originally convenient, is inefficient.

Meanwhile, most notebook computers only have one original lithium battery pack, so that the service time is short, the capacity is not high, and the cruising ability is relatively limited. Therefore, a single battery pack is far from meeting the requirement of the notebook computer for long-time work. In addition, when the capacity of the battery pack is reduced or the battery pack cannot be used, it is difficult for users to buy alternative products because the original battery pack is expensive and low in versatility.

Detailed Description

The following detailed description of embodiments of the present invention refers to the accompanying drawings.

Fig. 1 illustrates a schematic configuration diagram of an embodiment of a standby power supply apparatus of a notebook computer according to the present invention. Fig. 2 is a schematic diagram illustrating the interface of the device shown in fig. 1 corresponding to the interface on the motherboard of the notebook computer. Since the device provides electrical capacity through the stored battery, the backup power device will be referred to hereinafter as a battery device for ease of description. Referring to fig. 1 and 2, the battery device includes at least: a battery interface 10, a recess 12 and a receptacle 14. The battery interface 10 and the groove 12 are located on the same side of the accommodating portion close to the computer motherboard 20, and the battery stored in the accommodating portion 14 is plugged into the power interface J1 on the notebook computer motherboard 20 through the battery interface 10, and is electrically connected with the power interface J1 on the motherboard 20. The recess 12 is a free area reserved for an optical disk drive interface (ODD) J2 to accommodate the ODD interface J2, so that when the battery device is connected, the ODD interface J2 on the motherboard 20 of the notebook computer will not block the accommodating portion 14 from being placed at the position where the optical drive was inserted. In order to realize the plug and play function of the battery device and the optical drive, the distance H1 between the battery interface 10 and the groove 12 is equal to the distance between the power interface J1 of the notebook computer and the ODD interface J2.

The batteries placed in the receptacle 14 may include different types, such as lithium batteries, nickel metal hydride batteries, nickel cadmium batteries, or disposable alkaline batteries. The accommodating part 14 may store, for example, three lithium batteries connected in series, each of which has a voltage of 3.6V and a capacity of 1500mAh to 2500mAh, according to the three-dimensional size of the ODD of the notebook computer. According to calculation, the battery device can provide 10.8V as a backup power source and has a capacity of 1500mAh to 2500 mAh. Also for example, 20 batteries, which are No. 7 nickel metal hydride batteries, nickel cadmium batteries, or disposable alkaline batteries, may be stored in the housing portion 14. The connection mode is characterized in that 10 batteries are connected in series to form a first branch circuit, the remaining 10 batteries are connected in series to form a second branch circuit, and then the first branch circuit and the second branch circuit are connected in parallel. If the voltage of each battery is 1.5V and the capacity is 700mAh to 1000mAh, the battery device formed by 20 batteries can be used as a standby power supply and can provide 15V of voltage and 1400mAh to 2000mAh of capacity, and the endurance time of the machine is greatly prolonged.

Referring to fig. 2, when the battery device is connected to the notebook computer, the power interface J1 on the notebook computer motherboard 20 is electrically connected to the battery interface 10, and the ODD interface J2 is electrically connected to the groove 12, so as to supply power to the notebook computer through the battery device. Adopt the utility model discloses a battery equipment has not only utilized original ODD occupation space ingeniously, but also has prolonged the duration of a journey ability of machine. In addition, when a user needs to use the ODD, the user only needs to pull the battery device off and plug the ODD on to put the ODD into use.

In fig. 3, a System Management Controller (SMC) 30 on a motherboard 20 of a notebook computer includes a power management chip 32 for controlling a battery on the motherboard and a power management chip 36 for controlling an ODD battery. The original battery power management chip 32 is connected to the original lithium battery 34, and the power management chip 36 is connected to the ODD battery 38. Here, the ODD battery refers to a battery pack stored in the rear accommodating portion 14 of the battery device by using the ODD interface space. As can be seen from fig. 3, the original lithium battery 34 and the ODD battery 38 have separate power management chips, that is, in order to use the battery device of the present invention, the SMC of the notebook computer needs to extend a new power management chip circuit to control the ODD battery.

Unlike fig. 3, the SMC 40 on the notebook motherboard 20 includes a power management chip circuit 42, wherein a part of the power management chip circuit 42 is used to control the original lithium battery 34, and another part of the power management chip circuit 42 is used to control the ODD battery 38. Thus, the battery and the original battery in the notebook computer have a common power management chip, so that the notebook computer does not need to design a power management chip circuit for controlling the ODD battery 38 before using the battery device of the present invention, but only updates the original power management chip circuit to realize the compatible control of the original lithium battery 34 and the ODD battery 38. In contrast, the power management scheme of FIG. 4 appears to save more board real estate on the motherboard 20.

As can be seen from the above description, the battery device of the present invention can expand the power supply mode of the existing notebook computer from the two modes of the ac power supply and the originally-installed lithium battery to the ac power supply, the originally-installed lithium battery and the additional ODD battery. For example, when the alternating current is cut off, the original ODD device can be unplugged, and then a battery device is plugged in as a standby power supply, so that the endurance time of the machine is prolonged together with the original lithium battery. Or the original lithium battery is used for supplying power, and when the screen indicates that the power supply is insufficient, the battery equipment is plugged so as to continue the normal use state of the notebook computer. In addition, because the utility model provides an ODD battery is general type, and the purchase is convenient, consequently can strengthen notebook computer's product added value greatly.

Hereinbefore, specific embodiments of the present invention have been described with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
