Abstract
The utility model relates to an energy power supply recovering device for a notebook computer, which comprises a solar energy plate which can change light energy into electric energy. The solar energy plate is installed at a position where the backlight of the displaying screen of an LCD of a notebook computer can be adsorbed. The utility model also comprises a charging circuit which can realize that the battery charging of the notebook computer can be realized by electric energy. The solar energy plate can absorb the backlight of the screen of the LCD, the backlight can be converted into electric energy, and the battery charging to a notebook computer can be realized. The goal of energy recovery and reuse can be realized, and the service time of a computer can be prolonged.
Description
The utility model relates to a kind of energy source recovery apparatus, especially relates to a kind of energy source recovery apparatus that is used for notebook computer.
In today that computer develops rapidly, in order to satisfy various business people's demand, the type computer of carrying has become a kind of trend, so the volume of PC is dwindled again and again, make it to become the about and much the same notebook computer of notebook of volume size, computer also becomes a kind of carry-along data processor therefrom, allows the user can carry out Data Processing anywhere or anytime.
In order to realize the carrying convenience of notebook computer, generally be to use battery, as lithium battery or Ni-MH battery, as the power source of notebook computer, these batteries can recharge usually so that reuse.Yet, the employed battery of notebook computer now, between two to three hours, for the user that needs often use notebook computer, but slightly dislike not enough its average service time greatly two to three hours service time.
So the power-on time of battery has just become the important determinative that can notebook computer ongoing operation.In order to solve the problem of this respect, the manufacturer of notebook computer there's no one who doesn't or isn't makes great efforts to propose in this respect solution, for example in notebook computer, be provided with two batteries and electricity exchange (HOT SWAP) circuit, when the power shortage of first battery, electricity exchange (HOT SWAP) circuit can switch to the power supply supply second battery automatically, supply the power supply of notebook computer by second battery, the user just can not have no alternative but interruption of work because of the power shortage of battery thus.
In addition, also having the user to buy more battery voluntarily, when the electricity usage for the treatment of first battery finishes, with the notebook computer shutdown, is second reserve battery with first battery altering again, so also can prolong the service time of notebook computer.
From the above mentioned, no matter manufacturer or consumer wish to prolong the service time of notebook computer, what influence work because battery electric power is not enough is quite to perplex.
The display screen of notebook computer adopts the LCD element mostly, and the video picture mode of LCD is in LCD polishing behind, and is promptly so-called backlight, utilizes this LCD of making backlight to show its content.
The purpose of this utility model is to provide a kind of energy source recovery apparatus of notebook computer, it can be recycled the LCD of the notebook computer energy backlight, and the battery charge of electric energy to notebook computer to of converting, can not make the user have no alternative but interruption of work, really can prolong the service time of notebook computer because of the power shortage of battery.
For achieving the above object, the energy source recovery apparatus of notebook computer of the present utility model is characterized in that: include:
One becomes the solar panels of electric energy with transform light energy, and these solar panels are installed in the LCD display screen position backlight that can absorb this computer; And
One with the charge circuit of electric energy to the battery charge of this notebook computer.
The energy source recovery apparatus of described notebook computer is characterized in that: these solar panels are arranged on the lateral margin section part of LCD display screen.
The energy source recovery apparatus of described notebook computer is characterized in that: these solar panels are arranged on towards the direction place of LCD display screen back light.
After having adopted said structure, notebook computer energy source recovery apparatus of the present utility model, owing to be installed in the position backlight that can absorb notebook computer LCD display screen with solar panels, the LCD of the notebook computer energy backlight recycled converted to electric energy, utilize the battery charge of a charge circuit again to this notebook computer, so can prolong the service time of notebook computer, make the user can because of the power shortage of battery must interruption of work.
Below, the utility model is described in more detail with specific embodiment in conjunction with the accompanying drawings.
Figure 1A is the first embodiment synoptic diagram of the present utility model.
Figure 1B is the second embodiment synoptic diagram of the present utility model.
Fig. 2 is a schematic perspective view of the present utility model.
Fig. 3 is a functional-block diagram of the present utility model.
As Figure 1A and shown in Figure 2, energy source recovery apparatus synoptic diagram for notebook computer of the present utility model, mainly comprise: several solar panels 2,2 ', it is installed on the lateral margin section of this LCD display screen 10, backlight with the back light generator 3 (as cold-cathode tube or fluorescent tube) that reclaims this LCD display screen 10, and should backlightly convert electric energy to; And a charge circuit 4, utilize of battery 5 chargings (as shown in Figure 3) of this electric energy to this notebook computer 1.In addition, solar panels 2 also can be installed in the direction towards back light, shown in Figure 1B.
Consult Fig. 3, be functional block diagram of the present utility model, as shown in FIG., the utility model is mainly used in the transform light energy that will reclaim and becomes electric energy, again by 5 chargings of 4 pairs of batteries of charge circuit.When being equiped with two batteries in the notebook computer, if first dead battery, the power supply supply can be switched by second battery supplied, at this moment, can use device of the present utility model and come first battery charge.
Under the unbroken situation of system, be arranged on backlight that generator backlight 3 that solar panels 2 on LCD screen 10 inner peripheral end surfaces can absorb LCD screens 10 is sent, and transform light energy become electric energy, the electric energy of being changed is again via a charge circuit 4, to first battery charge.
Though the utility model has disclosed a preferred embodiment as mentioned above, so it is not in order to limit this creation, and on similar like product, use on LCD screen and the product backlight thereof also applicable device of the present utility model as palm PC (HPC) or personal digital assistant (PDA) etc.
