Detailed description of the invention

The embodiment of the present invention is described in detail below with reference to accompanying drawing.

First, charge prompting method according to embodiments of the present invention will be described.

The charge prompting method of the embodiment of the present invention is applied to the various electronic equipments of such as panel computer, smart mobile phone etc. Described electronic equipment includes the wireless charging of such as receiving coil etc. and receives unit such that it is able to be charged by wireless charging mode. That is, electric energy is received by electromagnetic induction from the wireless charging device of the transmitting terminal as wireless charging as the described electronic equipment of the receiving terminal of wireless charging. The principle of wireless charging is known to those skilled in the art, is not described in detail in this. Additionally, described electronic equipment also includes output unit, for exporting information to user. Described output unit can be the image output unit of such as display etc., it is also possible to be the output unit etc. of the voice-output unit of such as speaker etc. or other kinds of information.

Hereinafter, the charge prompting method of the embodiment of the present invention will be more fully described with reference to Fig. 1. When the charge prompting method of the embodiment of the present invention starts, described wireless charging device is in couple state with described electronic equipment. That is, between output and the input of described electronic equipment of described wireless charging device, existence closely cooperates and influences each other, and by the interaction of electromagnetic induction from described wireless charging device to described electronic equipment energy. Additionally, have been completed the various preparations realized needed for wireless charging such as initializing communication etc. between described wireless charging device and described electronic equipment, it specifically processes known to those skilled in the art, is not described in detail in this.

As it is shown in figure 1, first, in step S101, described charge prompting method, in each of multiple predetermined points of described electronic equipment, detects magnetic field intensity respectively.

Specifically, for instance hall device can be arranged by the described predetermined point on described electronic equipment, for detecting in magnetic field intensity between wireless charging device and described electronic equipment described in described predetermined point place. In one embodiment, the number of described predetermined point is three. Alternatively, described three predetermined points are not point-blank. Such as, described three predetermined points may be arranged to three summits with triangle. Alternatively, described triangle is equilateral triangle, i.e. described three predetermined points distance each other is equal. In another embodiment, the number of described predetermined point is four or more.

Although it is pointed out that and being described for hall device above, but it will be appreciated by those skilled in the art that and the invention is not restricted to this, but any element that can detect magnetic field intensity can be adopted. Although additionally, be described for three or more predetermined points above, but the invention is not restricted to this, but can apply to two, the situation of an even predetermined point. It is to say, statement " multiple " here also comprises " one " and the situation of " two ". Also will be described in detail with regard to this after a while.

It follows that in step S102, described charge prompting method, based on the multiple magnetic field intensities detected, calculates the first relative position relation between described electronic equipment and described wireless charging device.

Specifically, in the first example, it is assumed that the quantity of the plurality of predetermined point is three, and described three predetermined points not point-blank. in this case, it is possible to calculate the first relative position relation between described electronic equipment and described wireless charging device by the mode of such as triangle polyester fibre. more specifically, the step of described calculating may include that the first magnetic field intensity based on the first predetermined point detection in described three predetermined points, second magnetic field intensity of the second predetermined point detection in described three predetermined points, and the 3rd magnetic field intensity of the 3rd predetermined point detection in described three predetermined points, calculate the first distance between the predetermined reference point in described first predetermined point and described wireless charging device respectively, second distance between described second predetermined point and described predetermined reference point, and the 3rd distance between described 3rd predetermined point and described predetermined reference point, and based on described first distance, described second distance, described 3rd distance and described three respective positions of predetermined point, calculate described first relative position relation.

Such as, Fig. 2 A illustrates exemplary locations relation between described electronic equipment and described wireless charging device in this example, which schematically illustrates the predetermined reference point O of the three of described electronic equipment predetermined point a, b and c and described wireless charging device (in this example, being set to the midpoint of wireless charging device). In the example of Fig. 2 A, it is assumed that three predetermined points a, b, c arrange in the way of equilateral triangle, i.e. the mutual distance between three predetermined points is identical. The center that center o is described electronic equipment of the equilateral triangle formed by three predetermined point a, b and c.

Thus, the center O of wireless charging device position coordinates (x, y) can pass through following formula (1) and (2) draw:

$\left\{\begin{array}{c}A=f_1(a_x,a_y,x,y)=\sqrt{{(a_x-x)}^2+{(a_y-y)}^2}\\ B=f_1(b_x,b_y,x,y)=\sqrt{{(b_x-x)}^2+{(b_y-y)}^2}\\ C=f_1(c_x,c_y,x,y)=\sqrt{{(c_x-c)}^2+{(c_y-y)}^2}\\ L=b_x-a_x\end{array}\right.---\left(1\right)$

$\left\{\begin{array}{c}{B}_a=f_2\left(A\right)\\ B_b=f_2\left(B\right)\\ B_c=f_2\left(C\right)\end{array}\right.---\left(2\right)$

Wherein, the coordinate of the first predetermined point a is (a_x,a_y), the coordinate of the second predetermined point b is (b_x,b_y), the coordinate of the 3rd predetermined point c is (c_x,c_y), A, B and C respectively the first predetermined point a, distance between the second predetermined point b and the 3rd predetermined point c and the center O of wireless charging device, L is the mutual distance between three predetermined points. Additionally, B_a��B_bAnd B_cThe magnetic field intensity respectively detected at the first predetermined point a, the second predetermined point b and the three predetermined point c. f₁() is the expression formula for calculating the distance between 2. f₂The expression formula for calculating magnetic field intensity that () is known in the art, is also described further below.

From above-mentioned expression formula (2), the magnetic field intensity at a certain predetermined point place is the function of the distance between itself and the center O of wireless charging device. Thus, by the magnetic field intensity in described three predetermined point a, b and c place detection, it can be deduced that described three predetermined points distance each and between the O of center. By the distance A, B and the C that draw substitute into above table reach formula (1), can draw the center O of wireless charging device coordinate (x, y).

About the relation between the distance between predetermined point and center O and the magnetic field intensity that detects from described predetermined point, i.e. about f₂(), calculates as it is known by the man skilled in the art, following formula (3)-(6) can be passed through:

$B_z=\frac{{\mathrm{\μ}}_{0}I}{2\mathrm{\π}}[\frac{K}{\mathrm{\ρ}+\mathrm{\α}}+\frac{E}{\mathrm{\α}-\mathrm{\ρ}}]---\left(3\right)$

$K={\∫}_0^{\mathrm{\π}/2}\frac{\mathrm{d\φ}}{\sqrt{1-k^2{\sin }^2\mathrm{\φ}}}---\left(4\right)$

$E={\∫}_0^{\mathrm{\π}/2}\sqrt{1-k^2{\sin }^2\mathrm{\φ}}\mathrm{\π\φ}---\left(5\right)$

$k=\sqrt{\frac{4\mathrm{\α}r\sin \mathrm{\θ}}{r^2+{\mathrm{\α}}^2+2\mathrm{\α}r\sin \mathrm{\θ}}}---\left(6\right)$

Wherein, for any one in three predetermined point a, b and c, its spherical coordinate is Z (��, ��, ��), B_zFor the magnetic field intensity at described some place, ��₀For air permeability, I is the electric current in the coil of wireless charging device, �� be described point from loop coil centre point (namely, the center O of wireless charging device) distance, �� and the �� respectively spherical coordinate vertical angle from center O and horizontal sextant angle, �� is the toroidal radius of wireless charging device.

In wireless charging is applied, it is approximately considered ��=0, then K=E=pi/2.

Thus, $B_z=\frac{{\mathrm{\μ}}_{0}I}{4(\mathrm{\ρ}+\mathrm{\α})(\mathrm{\α}-\mathrm{\ρ})}=\frac{\mathrm{\α}{\mathrm{\μ}}_{0}I}{2({\mathrm{\α}}^2-{\mathrm{\ρ}}^2)}.$

In above-mentioned equation, ��₀Can as required be preset by those skilled in the art with �� and directly read from the memorizer of described electronic equipment. In one example, as the �� of air permeability₀Can be similar to and be set as 1, etc. In another example, can preset according to wireless charging standard as the �� of loop coil radius, for instance for 32.25mm, etc. In addition, the value of I obtains although can pass through to arrange current measurement device in wireless charging device, yet with this equation is being substituted in expression formula (1) and (2) to calculate the position coordinates (x of the center O of described wireless charging device, y) in process, the value of I can be offset accordingly, is therefore actually not required to learn the occurrence of I. As can be seen here, the magnetic field intensity of each predetermined point and the distance of the center O of its distance wireless charging device is square relevant.

Above, describe from the multiple magnetic field intensities detected, calculate the detailed process of the first relative position relation between described electronic equipment and described wireless charging device.

It is pointed out that in superincumbent calculating, be arranged as example with described three predetermined points in equilateral triangle mode and be described. But, the charge prompting method of the embodiment of the present invention is not limited to this, but can apply to the layout of various mode.

Such as, when three predetermined points arbitrarily arranged, three predetermined point a, b and c the length of side formed is shown in following formula (7):

$\left\{\begin{array}{c}{L}_{\mathrm{ab}}=\sqrt{{(a_x-b_x)}^2+{(a_y-b_y)}^2}\\ L_{\mathrm{bc}}=\sqrt{{(b_x-c_x)}^2+{(b_y-c_y)}^2}\\ L_{\mathrm{ca}}=\sqrt{{(c_x-a_x)}^2+{(c_y-a_y)}^2}\end{array}\right.$

Above-mentioned expression formula (7) is substituted into the 4th equation in expression formula (1), gets final product and mode similarly as described above determines the first relative position relation between described electronic equipment and described wireless charging device. It is to be noted, it is arranged in described electronic equipment owing to the position of described three predetermined points is relatively fixed, therefore, when learning the described length of side in advance, the position coordinates of described three predetermined points can be determined in advance by the described length of side and described position coordinates is stored in memory, in first three equation substituting into above-mentioned expression formula (1) when calculating described first relative position relation. It is of course also possible to directly arranged the position coordinates of described three predetermined points by those skilled in the art and store it in memorizer, in first three equation substituting into above-mentioned expression formula (1) when calculating described first relative position relation.

In addition it should be pointed out that, in superincumbent calculating, it is described for the situation of three predetermined points. But, the charge prompting method of the embodiment of the present invention is not limited to this, but can apply to the situation of less or more predetermined point.

Such as, when two predetermined points, Fig. 2 B illustrates exemplary locations relation between described electronic equipment and described wireless charging device in this example, which schematically illustrates the two of described electronic equipment predetermined point a and b. Skilled artisans appreciate that, in the way of similar with (2) by above-mentioned expression formula (1), the position relationship two kinds possible between described electronic equipment and described wireless charging device can be calculated as described first relative position relation in the present embodiment, namely, point O (x shown in Fig. 2 B, y) and O'(x, y). In this example, the abscissa of the central point of determined wireless charging device is that the line about two predetermined points is symmetrical. Hereafter, by the operation of step S103 that is described below, position relationship possible for the two is prompted to user, and heuristically placed between the position relationship that both is possible by user and determine finally suitable position relationship.

Compared with the example of above three predetermined point, the positioning precision of the charge prompting method of this example declines to some extent, and needs the exploratory operation of user to coordinate. But, the charge prompting method of this example is due to the decreased number of the setting element of required such as Hall element so that the weight of described electronic equipment correspondingly reduces, and cost also correspondingly reduces.

In addition, skilled artisans appreciate that, when a predetermined point, compared with the situation of above-mentioned two predetermined point, positioning precision can decline further, user needs more exploratory operation to be judged by the change of magnetic field intensity, but, it also can prompt the user with position relationship and user may finally be helped to realize location.

Additionally, when it will be appreciated by those skilled in the art that for four or more predetermined point, it is possible to realized location by the mode similar with the calculating of above three predetermined point, be not repeated at this.

In sum, those skilled in the art can arbitrarily select according to actual needs between the various implementations utilizing the difference of different number of predetermined point and predetermined point to place.

After the first relative position relation obtained between described wireless charging device and described electronic equipment, described charge prompting method proceeds to step S103. In step S103, the user of described electronic equipment, based on described first relative position relation, is pointed out by described charge prompting method.

Specifically, in one embodiment, when described electronic equipment includes display unit, described charge prompting method such as can show the image of the first relative position relation represented between described electronic equipment and described wireless charging device on described display unit, in order to the user of described electronic equipment could be adjusted to make the relative position between described electronic equipment and described wireless charging device meet normal place relation.

More specifically, described charge prompting method can obtain the prediction picture in the memorizer being stored in advance in such as described electronic equipment, described prediction picture includes the first pictorial element representing the central point of described electronic equipment. Next, described charge prompting method can based on the first relative position relation between the step S102 described wireless charging device obtained and described electronic equipment, appropriate position superposition in described prediction picture is for representing the second pictorial element of the central point of described wireless charging device, so that the relative position relation between described first pictorial element and described second pictorial element meets described first relative position relation. Thus, described charge prompting method generates final prompting image as shown in Figure 3, and outputs it on described display unit.

Specifically, Fig. 3 is the display schematic diagram that diagram applies on the electronic equipment of charge prompting method according to embodiments of the present invention. As it is shown on figure 3, on the viewing area 300 of described electronic equipment, comprise two prompting points. First prompting point 301 is the first pictorial element as above, represents the central point of described electronic equipment. Second prompting point 302 is the second pictorial element as above, represents the central point of described wireless charging device. User after viewing described prompting image by described display unit, it is possible to is adjusted correspondingly. Such as, in the situation shown in fig. 2, described wireless charging device can be moved by user to upper right side, so that described wireless charging device is directed at more with described electronic equipment, and is finally reached normal place relation, i.e. both centers coincide. Now, charge efficiency reaches the highest.

It is pointed out that prompting image as shown in Figure 3 is merely illustrative. Those skilled in the art as required, can design other various forms of prompting images, for instance only comprising image of word for representing described first relative position relation etc., it is intended to be included within.

In another embodiment, when described electronic equipment includes voice-output unit, described charge prompting method such as can point out the first relative position relation between described electronic equipment and described wireless charging device with voice output, in order to the user of described electronic equipment could be adjusted to make the relative position between described electronic equipment and described wireless charging device meet normal place relation.

Specifically, described charge prompting method based on described first relative position relation, can carry out voice message by the voice key word in expression orientation. Described voice message can provide the information of the first relative position relation directly represented between described electronic equipment and described wireless charging device, it is also possible to provides the information how prompting user adjusts. Such as, position relationship between described electronic equipment and described wireless charging device as shown in Figure 3, described voice message can be such as the information of " lower left of equipment that charger is positioned at you ", it is also possible to for such as " please moving over to the right your equipment " or the information of " please lower section adjusts your equipment to the left ".

Although it is pointed out that and being described for image output and voice output above, but, invention technician is it is understood that the invention is not restricted to this, but can provide various forms of prompting according to the form of electronic equipment and occupation mode. Such as, on described electronic equipment can built-in multiple LED backlight, and light according to described first relative position relation or strengthen the backlight of corresponding position. Again such as, described electronic equipment can built-in multiple vibration units, and vibrate in corresponding position according to described first relative position relation, etc.

In addition, it should further be noted that, although being described for the central point of the central point of described electronic equipment and described wireless charging device above, but skilled artisans appreciate that, the invention is not restricted to this, but can be calculated so that any point in described electronic equipment and described wireless charging device is as a reference point and point out.

Operation by step S101-S103 described above in detail, it is achieved that the charge prompting method of the embodiment of the present invention. After the user of described electronic equipment is pointed out, described charge prompting method can terminate. Alternatively, described charge prompting method can proceed to detect to determine that proceeding prompting is also off described prompting. Below, process in the case will be described in detail with reference to Fig. 4.

Fig. 4 is the flow chart processed further illustrating charge prompting method according to embodiments of the present invention. As shown in Figure 4, after the user of described electronic equipment is pointed out, first, in step S401, described charge prompting method, in each of the plurality of predetermined point of described electronic equipment, detects magnetic field intensity respectively again.

It follows that in step S402, described charge prompting method, based on the multiple magnetic field intensities again detected, calculates the second relative position relation between described electronic equipment and described wireless charging device.

The concrete process of step S401 and S402 is similar with the process with reference to the step S101 described in Fig. 1 and S102, is not described in detail in this.

After obtaining described second relative position relation, described charge prompting method judges whether described second relative position relation is the normal place relation between described electronic equipment and described wireless charging device. Specifically, the relation that described normal place relation such as aligns with the center of described wireless charging device for the center of described electronic equipment. That is, under described normal place relation, the center of described electronic equipment overlaps on the direction perpendicular with the plane of described electronic equipment with the center of described wireless charging device. Whether described charge prompting method can judge less than predetermined threshold value based on the distance between center and the center of described wireless charging device of electronic equipment described in described second relative position relation, preferably, it is possible to be whether zero judge based on this distance.

It follows that when judging that described second relative position relation is not described normal place relation, continue described charge prompting method. Now, described charge prompting method such as can continue to prompt the user with described first relative position relation. Alternatively, described second relative position relation again being detected and calculating gained by step S301 and S302 can be prompted to user by described charge prompting method, so that along with the adjustment of user reflects the position relationship between described wireless charging device and described electronic equipment more in real time.

On the other hand, when judging that described second relative position relation is described normal place relation, described charge prompting method stops described prompting.

It is to be noted, in each embodiment described above, it is placed in Different Plane although described electronic equipment is usually folded on the upper strata, direction vertical with the surface of described electronic equipment in actual applications with described wireless charging device, but, here the relative position relation assuming that described electronic equipment and described wireless charging device are projected to along (that is, on described stacked direction) on the direction vertical with the surface of described electronic equipment same plane gained is all represented about the statement of " relative position relation ".
