Therefore, the touch display is widely used in electronic devices such as smart phones, tablet computers, and smart watches. The panel serves as the operating interface.

Many electronic devices currently use capacitive touch panels to sense the user's contact position. However, since the capacitive touch panel is sensitive, when the user touches the touch panel by mistake, the electronic device may malfunction. Therefore, some manufacturers additionally provide a power sensor under the capacitive touch panel to sense the user's pressing force, and when the user presses the force greater than a specific value, the electronic device is commanded to execute the corresponding program. It can prevent the user from accidentally touching the malfunction of the electronic device.

The current force sensor is directly bonded to the peripheral area of the inner surface of the glass substrate of the touch panel, which may reduce the adhesion area of the glass substrate and the base, thereby increasing the risk of peeling off, and the glass substrate is directly adhered to the base. It will also reduce the force of the vibration device feedback.

An object of the present invention is to provide an electronic device for power sensing that not only senses the force that the protective cover is subjected to, but also provides the elastic structure required for stable support and vibration of the touch screen.

The outer frame has an accommodating space and an opening, and the display panel and the support frame are accommodated in the accommodating space. The protective cover is disposed corresponding to the opening and shields at least a portion of the support frame and at least a portion of the display panel, wherein the extension wall is spaced apart from the outer frame by a distance. The force sensor is disposed on the second surface of the support frame.

With the above embodiment, the support frame can surround the display panel and be superposed on the inner surface of the protective cover to support the protective cover. In addition, the force sensor can be disposed on the support frame, so that when the user touches the protective cover, the force of the protective cover can be transmitted to the force sensor through the support frame, so the force sensor can feel The strength of the protective cover was measured. Therefore, the above-mentioned power sensing electronic device can not only sense the strength of the protective cover, but also install a support frame around the protective cover to support the protective cover, thereby preventing the protective cover from being deformed by excessive force.

The extension wall 500 is spaced from the outer frame 1100 by a distance. The force sensor 400 is disposed on the second surface 320 of the support frame 300. In other words, the protective cover 100, the support frame 300 and the force sensor 400 are sequentially disposed to each other.

In the above embodiment, the support frame 300 is disposed on the inner surface 110 of the protective cover 100 and surrounds the display panel 200. In other words, the support frame 300 is disposed at a peripheral area of the inner surface 110 to support the protective cover 100. In addition, the force sensor 400 is disposed on the support frame 300, whereby when the user touches the outer surface 120 of the protective cover 100, the force received by the protective cover 100 can be transmitted to the force sensor through the support frame 300. 400, the force sensor 400 can sense the force that the protective cover 100 is subjected to. Therefore, the above-described power sensing electronic device 10 has both the effect of sensing the force of the protective cover 100 and the effect of supporting the protective cover 100.

In the present embodiment, the support frame 300 and the extension wall 500 are integrally formed to increase the structural strength of the support frame 300 and the extension wall 500. In other embodiments, the support frame 300 and the extension wall 500 may also be two plates, and the two plate systems are joined or adhered to each other.

In some embodiments, as shown in FIG. 2, the power sensing electronic device 10 includes a base 800. The display panel 200 is disposed on the susceptor 800. The outer frame 1100 includes a top frame body 1110 and a side frame body 1120 that are connected. The top frame 1110 covers the support frame 300, and the side frame 1120 covers the extension wall 500.

In other embodiments, the outer frame 1100 is separated from the protective cover 100, but a buffer structure (such as sponge or rubber, etc.) may be interposed therebetween to shield the lower support frame 300 and the extension wall 500.

In an embodiment, the protective cover 100 can be a touch panel. For example, the protective cover 100 can be a capacitive touch panel, a resistive touch panel, or an optical touch panel, but the invention is not limited thereto. For example, the protective cover 100 may include a transparent conductive pattern (not shown) therein. When the user touches the outer surface 120 of the protective cover 100, the touch IC (not shown) may be transparent. The capacitance value of the conductive pattern changes or the resistance value changes to obtain the touch position of the user. Therefore, the power sensing electronic device 10 can not only borrow The force sensor 400 senses the user's touch force, and the user's touch position can also be sensed by protecting the transparent conductive pattern in the cover 100. In some embodiments, the protective cover 100 may not be a touch panel. For example, the protective cover 100 may be a glass cover.

The sensing area 411 can sense the force, while the non-sensing area 412 cannot sense the force. The force transmitting body 600 is interposed between the sensing region 411 and the second surface 320, and the non-sensing region 412 is separated from the second surface 320 and the force transmitting body 600.

In this way, the force transmitting body 600 can transmit the force to the sensing region 411 intensively without transmitting the force to the non-sensing region 412, thereby facilitating the force sensor 400 to effectively sense the force of the protective cover 100. .

In some embodiments, the sensing region 411 may include a Force-Sensing Resistor. The resistance value of the force-sensitive resistor changes with the strength of the force-sensitive resistor, so it can be calculated from the resistance value change of the force-sensitive resistor. The force that the force sensor 400 is subjected to. The non-sensing region 412 may include traces that connect the force-sensitive resistors, but do not include force-sensitive resistors. Therefore, the sensing area 411 can sense the force, while the non-sensing area 412 cannot sense the force. When the force transmitting body 600 is interposed between the sensing region 411 and the second surface 320, and the non-sensing region 412 is separated from the second surface 320 by a gap, the force transmitting body 600 can collectively transmit the force to the sensing region. The force sensitive resistor of 411 facilitates the force sensor 400 to effectively sense the force experienced by the protective cover 100. In some embodiments. The force transmitting body 600 can be a plastic gasket, but the invention is not limited thereto.

FIG. 4 is a bottom view of the power sensing device 10 of FIG. 2 viewed from a viewing angle V1 when the base device 800 is not provided. As shown in FIG. 4 , in the present embodiment, the force sensor 400 can be a two-shaped sensing structure, and the two strip-shaped sensing structures can be respectively located on opposite sides of the display panel 200 .

FIG. 5 is a perspective view of the power sensing electronic device 10a according to another embodiment of the present invention. FIG. 6 is a bottom view of the power sensing electronic device 10a shown in FIG. 5 viewed from a viewing angle V2 without a base. As shown in FIGS. 5 and 6, the main difference between the power sensing electronic device 10a and the aforementioned power sensing electronic device 10 is that the power sensor 400a of the present embodiment has a plurality of flat cylindrical feelings. Measuring structure.

FIG. 7 is a perspective view of the power sensing electronic device 10b according to another embodiment of the present invention. Figure 8 shows the sense of power shown in Figure 7. The lower view of the electronic device 10b as viewed from the viewing angle V3 when the electronic device 10b is not provided. As shown in FIGS. 7 and 8, the main difference between the power sensing electronic device 10b and the aforementioned power sensing electronic device 10 is that the number of the power sensors 400b is one, and the force sensor 400b is An annular structure surrounds the display panel 200.

FIG. 9 is a perspective view of the power sensing electronic device 10c according to another embodiment of the present invention. Fig. 10 is a cross-sectional view of the power sensing electronic device 10c shown in Fig. 9 taken along line B-B'. As shown in FIGS. 9 and 10, the main difference between the present embodiment and the above-described embodiment is that the power sensing electronic device 10c of the present embodiment includes the vibration device 700 and is provided corresponding to the display panel 200. The vibration device 700 is configured to vibrate the protective cover 100 when the force sensed by the force sensor 400 is greater than a predetermined value. In contrast, when the force sensed by the force sensor 400 is less than or equal to the preset value, the vibration device 700 does not vibrate the protective cover 100.

In this way, when the force applied by the user to the protective cover 100 is greater than a preset value, the vibration device 700 vibrates the protective cover 100, and the user knows that the electronic device 10c has been successfully input to the power sensing device. The control IC (not shown) is further provided, and in addition, the display panel 200 can control the display screen according to the instruction. In contrast, when the power applied by the user to the protective cover 100 is less than or equal to a preset value, the control IC of the power sensing electronic device 10c does not input an instruction to the display panel 200, and the vibration device 700 does not protect the same. The cover 100 vibrates to prevent malfunction of the power sensing electronic device 10c. The above preset value may be determined by the control IC of the power sensing electronic device 10c. For example, the control IC may be based on the normal pressing force of the human finger. To determine the above preset value.

As shown in FIG. 10, since the display panel 200 can be placed on the susceptor 800 without being fixed to the susceptor 800, the display panel 200 can be moved relative to the susceptor 800 to vibrate on the susceptor 800. The vibration device 700 includes a first magnetic element 710 and a second magnetic element 720. The first magnetic element 710 is disposed on the base 800. The second magnetic element 720 is disposed on the display panel 200. More specifically, the first magnetic element 710 is fixed to the base 800, and the second magnetic element 720 is fixed to the display panel 200. The magnetic field of the first magnetic element 710 or the magnetic field of the second magnetic element 720 is variable such that the first magnetic element 710 and the second magnetic element 720 are relatively reciprocating.

In this way, the second magnetic component 720 can drive the display panel 200 to reciprocate relative to the base 800 to vibrate the display panel 200, and since the display panel 200 is fixed to the inner surface 110 of the protective cover 100, when the display panel 200 vibrates At this time, the protective cover 100 vibrates together with the display panel 200, and the user knows that it has successfully input a control IC for instructing the power sensing electronic device 10c. In order to facilitate the protection of the cover 100 vibration, in the present embodiment, the outer frame 1100 and the protective cover 100 may be separated by a gap to provide space for the protective cover 100 to vibrate. In other embodiments, a buffer structure (such as sponge or rubber, etc.) is interposed between the outer frame 1100 and the protective cover 100, and the buffer structure is deformable to allow the protective cover 100 to vibrate.

For example, the first magnetic element 710 can include a spiral tube 711 and a magnetic core 712. The spiral tube 711 is wound around the magnetic core 712. The second magnetic element 720 can be a magnet. In use, the spiral tube 711 can be applied with alternating current so that the magnetic field generated by the spiral tube 711 changes over time, allowing the second magnetic Element 720 reciprocates relative to first magnetic element 710. In some embodiments, when the spiral tube 711 is not energized, the first magnetic element 710 and the second magnetic element 720 can be separated by a gap, so that when the spiral tube 711 is energized, the second magnetic element 720 can be generated by the spiral tube 711. The magnetic field is attracted to move toward the first magnetic element 710. In other embodiments, the first magnetic element 710 may also not include the magnetic core 712.

In an embodiment, as shown in FIG. 10, the extension wall 500a is connected to the base 800. Thereby, when the display panel 200 drives the protection cover 100 to vibrate, the protection cover 100 drives the support frame 300 to vibrate together with the extension wall 500a. When the extension wall 500a, the support frame 300, the protective cover 100, and the display panel 200 are not separated from the entire power sensing electronic device 10c. It is noted that in order to allow the extension wall 500a connected to the base 800 to vibrate, in some embodiments, the minimum force that causes the extension wall 500a to bend is less than the minimum force that causes the extension wall 500a to disengage from the base 800. In other words, the extension wall 500a can be bent without being detached from the base 800. More specifically, when the extension wall 500a is subjected to a certain degree of lateral stress, the extension wall 500a is bent but not separated from the base 800.

In this way, when the second magnetic element 720 drives the display panel 200, the protective cover 100 and the support frame 300 to reciprocate, the extension wall 500a can swing in a curved manner without leaving the base 800. Therefore, the protective cover 100 can vibrate without departing from the entire power sensing electronic device 10c.

Further, referring to FIG. 11 , the figure shows that the power sensing electronic device 10c of FIG. 10 does not have the outer frame 1100, and the viewing angle V4 is viewed. Side view of it. As shown in FIG. 11, the extension wall 500a includes a flexible sheet body 510, a plurality of fixed sheets 520, and a plurality of slots 530. The fixing piece 520 and the flexible piece 510 are connected to the base 800. The two fixing pieces 520 are located on opposite sides of a flexible piece 510, and the two slots 530 are located on opposite sides of the flexible piece 510, and are separated from the flexible piece 510 and the fixing pieces on both sides thereof. 520. Further, the flexible sheet body 510 is separated from the fixing sheets 520 on the left and right sides thereof, so that the flexible sheet body 510 can be restrained from being bent back and forth without being restrained by the fixing sheets 520 on the left and right sides thereof. As a result, when the protective cover 100 vibrates, even if the flexible sheet body 510 is coupled to the base 800, it can be swung back and forth in a curved manner without being restrained by the left and right fixed sheets 520. It should be understood that the terms "before", "after", "left", "right", "upper" or "lower" as used throughout this specification are only intended to help the reader understand the relative position or direction of the components of the present invention. Instead of limiting the invention.

In other words, at least two flexible sheets 510 are respectively located on opposite sides of the support frame 300. In this way, the flexible sheets 510 located on opposite sides of the support frame 300 can be swung in the alignment direction A in a curved manner, and the support frame 300, the protective cover 100 and the display panel 200 can be driven by the vibration device 700. The vibration is accelerated along the arrangement direction A, and when the vibration is applied, the support frame 300, the protective cover 100, and the display panel 200 are not separated from the entire power sensing electronic device 10c. In order to facilitate the vibration of the support frame 300 and the extension wall 500a, the extension wall 500a and the outer frame The 1100 is spaced apart by a distance that provides space for the support frame 300 and the extension wall 500a to vibrate.

As shown in FIG. 10, the flexible sheet 510 can be locked to the base 800 and define a gap G with the base 800 for the user to press the outer surface 120 of the protective cover 100 to protect the cover 100 and the support frame 300. The extension wall 500a can move downward together. Further, the power sensing electronic device 10c further includes a lock attachment 900. The bendable sheet body 510 has a through hole 513. The lock attachment 900 is attached to the base 800 through the through hole 513 and the gap G. The lock attachment 900 has a length direction L. The length direction L is substantially perpendicular to the outer surface 120 of the protective cover 100. When the protective cover 100 is unstressed, the bendable sheet 510 maintains a gap G with the base 800. When the user presses the outer surface 120 of the protective cover 100, the gap G allows the protective cover 100, the support frame 300 and the extension wall 500 to move downward along the length direction L of the lock attachment 900.

As shown in FIG. 10, the flexible sheet body 510 may include a first sub-sheet body 511 and a second sub-sheet body 512. The first sub-sheet body 511 is extended by the second surface 320 of the support frame 300 along the first direction D1. The second sub-sheet body 512 is extended by the first sub-sheet body 511 along the second direction D2. The first direction D1 intersects the second direction D2. For example, the first direction D1 and the second direction D2 may be substantially perpendicular. The second direction D2 is substantially parallel to the inner surface 110 and the outer surface 120 of the protective cover 100. The through hole 513 is opened in the second sub-sheet body 512. Further, the first direction D1 is substantially parallel to the longitudinal direction L of the lock attachment 900, and the second direction D2 is substantially parallel to the arrangement direction A. In this way, the second sub-sheet 512 can be firmly locked to the base 800, and the first sub-sheet 511 can be swung in a curved manner along the arrangement direction A to facilitate The frame 300 and the protective cover 100 vibrate in the arrangement direction A.

Fig. 12 is a cross-sectional view of the power sensing electronic device 10c of Fig. 9 taken along line C-C'. As shown in FIG. 12, the power sensing electronic device 10c may further include a buffer structure 1000.
