Detailed ways

This specification discloses a flexible electronic device and a method for installing a plurality of components included therein. Through this installation method, the installation position of the components in the flexible electronic device can be determined according to the needs of the designer, and an appropriate weight distribution can be obtained to facilitate the user's operation.

As shown in FIG. 1A , the substrate 110 is used in the flexible electronic device to carry various required components. In order to make it easy for readers to understand, various components carried by the substrate 110 are not marked in the figures for the time being. The base plate 110 itself is composed of a flexible material, so it can be folded according to the user's needs. In FIG. 1A , the areas 110a and 110b surrounded by dotted lines represent folding areas pre-planned by the designer, respectively. In some embodiments, since the width of the folded region is relatively small relative to the size of the substrate 110 , it can also be represented by a single dotted line.

In an actual product, the areas 110a and 110b enclosed by the dashed lines may be recognizable or unrecognizable by the naked eye, and the dashed lines may be close to straight lines, or may be curved lines or a combination of straight lines and curved lines. The regions 110a and 110b enclosed by the dotted lines may be continuous lines or discontinuous line segments.

In this embodiment, the base plate 110 is designed to be foldable into different embodiments of one fold as shown in FIG. 1B or two folds as shown in FIG. 1C . FIGS. 2A-2C are top views corresponding to FIGS. 1A-1C respectively, that is, FIG. 2B shows one fold, and FIG. 2C shows two folds.

As shown in FIG. 1A , the mounted components (not marked) can be distributed in four different component mounting regions Z _i (Z ₁ , Z ₂ , Z ₃ , Z ₄ ) defined by the dotted line regions 110 a and 110 b according to the design requirements. )middle. The areas of the regions Z _i may or may not be equal to each other. In some embodiments, when the substrate 110 is bent through the dashed regions 110a and 110b, each region Z _i is not bent relative to the dashed regions 110a and 110b.

g1 to g3 represent the geometric centers of different shapes in Figs. 2A-2C, respectively. The definition of the geometric center is known to the skilled person and can be obtained by geometric calculation. For example, the center of a circle is the geometric center of a circle, and the The intersection of the angle lines is its geometric center.

w1 to w3 respectively represent the center of gravity of a plurality of elements in different folded states in FIGS. 2A-2C . The common center of gravity of the plurality of components can be calculated according to the weights and the arrangement positions of the plurality of components and with reference to the folded state of the substrate 110 .

A feature of the present disclosure is that by a method, the components to be placed can be placed on the substrate 110, and in the use state in different shapes, the center of gravity and the geometric center can be aligned with each other, or overlap, or can be as shown in Fig. 2A-2C are maintained at a certain distance d.

In the use state, when the center of gravity of the plurality of components is closer to the geometric center of the substrate, the flexible electronic device can provide preferred weight distribution. That is, the user only needs to hold the geometric center position of the substrate to maintain the balance of the flexible electronic device, so that the flexible electronic device will not be overturned and dropped due to uneven weight distribution during use.

When placing a plurality of components, the usage form of the flexible electronic device can be considered in advance. For example, the shape of the substrate 110 includes the unfolded state as shown in FIG. 1A , the primary folded state as shown in FIG. 1B , and the secondary folded state as shown in FIG. 1C . If the flexible electronic device is only used in the unfolded state, and the primary folding and secondary folding states are only required for storage, then when designing the positions of multiple components, it is only necessary to make the center of gravity w1 in the unfolded state close to The geometric center g1 is sufficient. However, if the flexible electronic device can be operated in the first-fold or second-fold state, in addition to making the center of gravity w1 close to the geometric center g1, it is also necessary to make the center of gravity w2 close to the geometric center g2, the center of gravity w3 is close to the geometric center g3.

Referring to FIG. 2A , the center of gravity w1 of the plurality of elements does not exactly overlap with the geometric center g1 , but falls at a distance d from the geometric center g1 . Due to the fixed weight of most of the components of the flexible electronic device, and considering factors such as the installation area, the relative position between components and the connection relationship, and the construction error during installation, it is usually difficult to make the center of gravity of multiple components exactly overlap with the center of the combination. . Generally speaking, when placing multiple components, if the center of gravity does not exactly overlap the geometric center, but if the center of gravity is only a distance d from the geometric center, the flexible electronic device can still maintain a balanced state without affecting the use of Convenience. In order to maintain balance, the actual value of the distance d is usually affected by factors such as the shape of the substrate and the total weight of the flexible electronic device. If the distance d is relative to the maximum distance D between the geometric center g1 and the edge of the substrate, the distance d is preferably not More than 0.1D, preferably not more than 0.05D.

The plurality of elements may be a camera element, a loudspeaker element, a battery, a button, and the like. A plurality of elements are generally inflexible, so each element is mainly disposed in one of the regions Z _i , and does not overlap with the dashed-line regions 110a and 110b for folding. When designing the installation positions of multiple components, computer simulation and other methods can be used to assist, and according to design requirements, for example, the components with the largest volume or the heaviest weight can be installed in sequence, etc., which will not be repeated here.

In some embodiments, the areas of the regions Z _i match, for example, are equal or approximately equal, and the folding methods thereof are also approximately symmetrically folded. Therefore, the weight of multiple components can be evenly distributed in each zone Z _i (that is, dividing the total weight of multiple components by the number of zones Z _i is the weight of the components arranged in each zone Z _i ) , so that the center of gravity w1 of the plurality of elements is close to the geometric center g1 of the substrate in the unfolded state. For example, the difference between the total weight of the elements arranged in any one of the regions Z _i and the total weight of the elements arranged in the other region Z _i is preferably not more than 3%. That is, if the total weight of the components set in the zone Z ₁ is m1, and the total weight of the components set in the zone Z ₂ is m2, the following relationship should be satisfied:

Furthermore, since the weights of the regions Z _i are matched, eg, equal or approximately equal, in the first-fold and second-fold implementations, the centers of gravity w2 and w3 of the multiple elements can still remain close to the geometric centers g2 and g3. Or, in some embodiments, the center of gravity of the elements arranged in each zone Z _i can be further made close to the geometric center of the zone Z _i .

In some embodiments, although the areas of the regions Z _i are not equal to each other, the above-mentioned method can also be used to set the components according to the area ratio of the regions Z _i , so that the area of each region Z _i is equal to the total of the components arranged therein. The weight ratios are all equal, so that the weight distribution of the flexible electronic components is more uniform. Furthermore, referring to the above method, the center of gravity of the elements arranged in each region Z _i can be made close to the geometric center of the region Z _i .

In some embodiments, the folding method is asymmetrical folding, and as described above, the center of gravity w1 of the multiple elements can be made close to the geometric center g1 of the substrate, and in the implementation of one-time folding and two-folding, the The centers of gravity w2 and w3 of the plurality of elements can still be maintained close to the geometric centers g2 and g3. In this way, even if the folding method is asymmetrical folding, the balance of the weight of the flexible electronic component can be maintained, so as to avoid a feeling of unbalance when the user holds it.

In some embodiments, since the weight of the substrate is not uniformly distributed, when mounting the multiple components, the weight of the substrate in different regions Z _i may be considered so that the total center of gravity of the multiple components and the substrate is close to the geometric center of the substrate. Similarly, considering the usage situation, the total center of gravity of a plurality of components and substrates after the primary folding and the secondary folding can still be close to the geometric center of the substrate in the implementation of the primary folding and the secondary folding. Furthermore, similar to the above method, the total weight of the components and substrates arranged in any zone Z _i can also be matched with the total weight of the components and substrates arranged in another zone Z _i , for example, the same or approximately the same. , or make the difference no more than 3%.

The plurality of elements can be further divided into positioning elements and non-positioning elements. Positioning components refer to components that must be set at predetermined positions on the substrate according to usage requirements or limitations of hardware settings, such as camera components, amplifier components or buttons, etc.; Those that do not affect ease of use or hardware setup difficulties, such as batteries. Therefore, the positioning elements can be set at predetermined positions on the substrate first, and then the non-positioning elements can be set, so as to adjust the position of the center of gravity of the multiple elements.

On the other hand, some elements of the flexible electronic device may be separately divided. For example, the battery can be divided into several battery assemblies with equal or unequal weights, which are respectively arranged in different regions Z _i on the substrate 110 , and then connected to each other through wires. In this way, the position of the center of gravity can be further adjusted to achieve optimal weight balance; at the same time, the installation area of the battery can be enlarged, the thickness of the battery can be reduced, and the ultra-thinning of the flexible electronic device can be facilitated.

In detail, please refer to FIG. 3 . In one embodiment, the battery is divided into several battery components B _i . The four battery components B ₁ , B ₂ , B ₃ , and B ₄ shown in FIG. 3 , In fact, the total number of battery components B _i can be adjusted according to requirements, and the size, power, weight, etc. of each battery component B _i can also be the same or different from each other. A plurality of battery packs B _i (B ₁ , B ₂ , B ₃ , B ₄ ) and a plurality of elements E _i (E ₁ , E ₂ , E ₃ ) other than batteries are arranged in the region Z _i on the substrate 110 , And its total center of gravity is close to the geometric center of the substrate 110 . Each region Z _i may be provided with one or more elements E _i and battery components B _i respectively, or may not be provided with elements E _i or battery components B _i . The three elements E _i and the four battery assemblies B _i shown here are respectively arranged in different Z _i , but not limited thereto.

In some embodiments, several components E _i other than batteries may be arranged in the region Z _i on the substrate 110 first, and then several battery components B are arranged in the region Z _i on the substrate 110, so that the The center of gravity is located approximately at the geometric center of the substrate 110 .

In some embodiments, the areas of the regions Z _i are approximately equal, so the total weight of the components that should be arranged in the regions Z _i can be calculated in advance, and then the weight of the battery components B _i arranged in the regions Z _i can be allocated accordingly. , and the total weight of the components set in any region Z _i is approximately equal to the total weight of the components set in the other region Z _i , so that the center of gravity of all components (including the battery) is located close to the geometric center of the substrate 110 . For the embodiment in FIG. 3 , the total weight of B ₁ and E ₁ in the Z ₁ area, the total weight of B ₂ and E ₂ in the Z ₂ area, and the B ₃ and E in the Z ₃ area The total weight of ₃ and the total weight of B ₄ in the Z ₄ zone are approximately equal.

In some embodiments, the center of gravity of all elements (including batteries) in each region Z _i and the geometric center of each region Z _i also substantially overlap. 2A to 2C, the center of gravity of all elements (including batteries) in each region Z _i has a distance d from the geometric center, and the maximum distance between the geometric center of each region Z _i and the substrate boundary in this region is defined. is D, the distance d is preferably not greater than 0.1D, preferably not greater than 0.05D. In this way, the flexible electronic device can have a preferred weight balance in any folded state.

The batteries in each area can be connected by circuit C, for example, between the battery B ₁ and the battery B ₂ . The circuit can be designed to connect battery B ₁ and battery B ₂ to each other in series or parallel. Circuit C can be shown in Figure 4, including several modules.

Circuit C may have a detection module and a switch module. In some embodiments, the power of the components in each zone Z _i can be preferentially supplied by the respective battery B _i , and the batteries in different zones, such as the switch module of the circuit C between the battery B ₁ and the battery B ₂ , will be _The current flow between the battery B1 and the battery B2 is prohibited in _an open state. At the same time, the detection module of the circuit C between the battery B ₁ and the battery B ₂ can detect the electric power of the battery B ₁ and the battery B ₂ , when the electric power of any one of the batteries is lower than a set value (for example, lower than 20%) For example, when the power of the battery B ₁ is lower than 20%, the switch module is connected to the battery B ₁ and the battery B ₂ in an on state, so that the battery B ₂ can supply power to the components in the zone Z ₁ .

In addition, the plurality of elements may further include one or more counterweights, and the counterweights are only used to achieve weight balance and have no other functions substantially. Since the counterweight itself has no other functions, it is not necessary to consider the relative position and connection relationship with other components, and its weight can also be set according to the needs, and it can even be made of flexible materials, which has a high degree of freedom in the setting position. degree, so as to balance the center of gravity of the multiple elements to achieve the optimal weight balance.
