Description

Technical Field

[0001] The present application relates to the field of touch-related technologies, and in particular to a touch panel and an electronic device. Background Art

[0002] The touchpad senses the position and movement of the user's finger through the touch sensor and controls the movement of the pointer on the display interface. The pressure touchpad eliminates the physical buttons of the conventional touchpad and replaces the physical buttons with pressure sensing devices and tactile feedback devices to achieve operations such as confirmation and calling up menus.

[0003] In order to continue users' usage habits of conventional touchpads, pressure touchpads usually use tactile feedback devices to simulate the feeling of pressing and bouncing physical buttons. The quality of user experience depends largely on the design of the tactile feedback device.

[0004] The overall structure of the tactile feedback device in the related art is complex and large in size, which occupies a large amount of space on the touch panel and is not conducive to the miniaturization design of the touch panel. Utility Model Content

[0005] The embodiments of the present application disclose a touch panel and an electronic device, which can simplify the structural design of a tactile feedback device and reduce the space occupied by the touch panel, thereby facilitating the miniaturization design of the touch panel.

[0006] In order to achieve the above objectives, in a first aspect, the present application discloses a touch panel, the touch panel comprising:

[0007] Circuit boards;

[0008] A touch panel, wherein the touch panel is arranged on one side of the circuit board;

[0009] A bracket, wherein the bracket is elastically connected to a side of the circuit board facing away from the touch panel;

[0010] a pressure sensing module, the pressure sensing module being disposed on the bracket and electrically connected to the circuit board; and

[0011] A power component is arranged on a side of the circuit board away from the touch panel, the power component includes a coil structure and a magnet, the coil structure is electrically connected to the circuit board, the circuit board is used to control the coil structure to be powered on according to the pressure signal detected by the pressure sensing module, and the coil structure is configured to generate a magnetic field with the magnet when powered on to drive the touch panel to vibrate.

[0012] The first aspect of the present application provides a touchpad. By arranging the bracket, the pressure sensing module, and the power component on the side of the circuit board away from the touch panel, and arranging the pressure sensing module on the bracket. In this way, the pressure sensing module can detect the deformation of the bracket to detect the pressure corresponding to the touch action on the touch panel. Thus, the circuit board can control the coil structure of the power component to be energized according to the pressure signal sensed by the pressure sensing module. As a result, the coil structure can generate a magnetic field with the magnet to drive the touch panel to vibrate, thereby realizing vibration feedback. It can be seen that for the touchpad of the present application, by arranging the bracket, the pressure sensing module, and the power component on the side of the circuit board away from the touch panel, the space of the circuit board can be reasonably utilized, making the overall structure of the touchpad more compact and conducive to realizing the miniaturized design of the touchpad.

[0013] In addition, in the touchpad of the present application, since the power component is directly arranged on the circuit board, the vibration transmission loss can be reduced, making the vibration feedback more direct and effective.

[0014] As an optional implementation manner, the bracket includes a connecting portion and a cantilever portion. The connecting portion is configured to be firmly connected to the housing of the electronic device, and the cantilever portion is elastically connected to the circuit board; the pressure sensing module is arranged on the cantilever portion. By the bracket including the cantilever portion and the cantilever portion being elastically connected to the circuit board, when the touch panel is touched, the cantilever portion can deform along the thickness direction of the circuit board in response to the touch action, and further the pressure sensing module can detect the deformation to feedback a pressure signal to the circuit board.

[0015] In addition, since the bracket further includes a connecting portion, the touchpad can be fixed to the housing of the electronic device by using the bracket, so that the touchpad can be fixed and supported without additionally increasing the space occupied by fixing parts on the circuit board.

[0016] As an optional implementation manner, the bracket includes a first arm, a second arm, and a third arm. The first arm and the second arm are arranged opposite to each other. The first arm and the second arm both include the connecting portion and the cantilever portion. The third arm is connected to the connecting portions of the first arm and the second arm. In this way, the bracket has at least two connecting portions and cantilever portions. On the one hand, it can make the force more balanced when the bracket is fixed to the electronic device; on the other hand, it can also make the bracket respond more evenly to the touch action of the touch panel.

[0017] As an alternative implementation, both the first arm and the second arm each include two of the cantilever portions and one connecting portion, and the two cantilever portions are respectively connected to two ends of the connecting portion. In this way, it is equivalent that the bracket includes four cantilever portions and two connecting portions, so that the four cantilever portions are arranged facing each other in pairs, which can further make the bracket respond to the touch action of the touch panel more evenly.

[0018] As an alternative implementation, the first arm, the second arm, and the third arm enclose a power space on the circuit board, the coil structure is located in the power space, and the coil structure is fixed to the circuit board, and the magnet is fixed to the third arm. This power space can be used to arrange power components, so as to realize the reasonable use of the space of the circuit board and further realize the miniaturized design of the touch panel.

[0019] In addition, by fixing the coil structure to the circuit board and arranging the magnet on the third arm, the structural compactness design of the touch panel can be further realized, which is beneficial to the miniaturized design of the touch panel.

[0020] As an alternative implementation, the pressure sensing module includes a flexible printed circuit board and a plurality of pressure sensors. The flexible printed circuit board includes a first flexible portion, a second flexible portion, and a third flexible portion connected between the first flexible portion and the second flexible portion. The first flexible portion and the second flexible portion are arranged facing each other. The first flexible portion is arranged on the first arm, the second flexible portion is arranged on the second arm, and at least a part of the third flexible portion is arranged on the third arm;

[0021] Among the plurality of pressure sensors, some of the pressure sensors are arranged on the first flexible portion, and the other part of the pressure sensors are arranged on the second flexible portion.

[0022] The pressure sensing module includes a pressure sensor and a flexible printed circuit board, so that the flexible printed circuit board can be used to realize the electrical connection between the pressure sensor and the circuit board, and at the same time, the bracket can also support the flexible printed circuit board, so as to support the pressure sensor, without additionally increasing the structure for the pressure sensing module, making the overall structure of the touch panel simpler.

[0023] In addition, by arranging a plurality of pressure sensors and corresponding to the first arm and the second arm arranged facing each other, the arrangement of the pressure sensors is uniform. Furthermore, when the user touches the touch panel, the pressure sensors sense the touch action more stably and evenly, avoiding the situation of unbalanced sensing. In addition, the setting of a plurality of pressure sensors can make the touch panel be sensed no matter where the user presses it, and the pressure sensing effect is better.

[0024] The flexible circuit board adopts a design including a first flexible part, a second flexible part and a third flexible part, which can realize the simultaneous connection of the multiple pressure sensors and the unified electrical connection of the multiple pressure sensors to the circuit board, making the electrical connection method between the pressure sensing module and the circuit board simpler.

[0025] As an optional implementation, there are four pressure sensors, and the four pressure sensors are respectively arranged on the first flexible portion and the second flexible portion in pairs. By arranging four pressure sensors and arranging them in pairs, the arrangement of the pressure sensors is more uniform, and no matter where the user touches, it can be sensed, and the sensing accuracy is higher.

[0026] As an optional implementation, the pressure sensor is arranged at the corner of the circuit board, the bracket is at least partially located at the corner of the circuit board, and the coil structure and the magnet are arranged in the middle of the circuit board. By arranging the pressure sensor at the corner of the circuit board, and the coil structure and the magnet in the middle of the circuit board, no matter where the user touches the touch panel, it can be detected and the corresponding vibration feedback can be achieved, thereby achieving full-domain feedback of the touch panel. That is, the touch panel is formed as a full-domain touch panel, and the touch feedback experience is better, which is conducive to improving the user experience.

[0027] As an optional implementation, the circuit board includes a first plate body and a second plate body, the touch panel is arranged on one side of the first plate body, the bracket and the power assembly are both arranged on the side of the first plate body away from the touch panel, the second plate body is located on the side of the bracket away from the first plate body, and the second plate body is electrically connected to the first plate body, the second plate body is configured to arrange electronic devices, and the pressure sensing module is electrically connected to the second plate body. By setting the circuit board to include the first plate body and the second plate body, the bracket, the power assembly and the pressure sensing module can all be arranged on the first plate body, and the second plate body is used to arrange the electronic devices. In this way, both the first plate body and the second plate body can be set smaller in length and width, so as to realize the miniaturization design of the touch panel. In addition, the design of the circuit board including two plates can separate the arrangement of electronic devices from the arrangement of devices such as pressure detection and vibration feedback, and do not interfere with each other, thereby further facilitating the layout of the touch panel.

[0028] Second aspect, the present application also discloses an electronic device, which includes a housing and a touchpad as described in the second aspect above. An installation groove is provided on the housing, the touchpad is installed in the installation groove, and the touch panel covers the opening of the installation groove to be exposed to the installation groove. The electronic device with this touchpad can also achieve comprehensive vibration feedback, providing a better user experience, and can also achieve a miniaturized and thinner design of the electronic device.

[0029] Compared with the prior art, the beneficial effects of the present application are as follows:

[0030] For the touchpad and the electronic device disclosed in the present application, by arranging the bracket, the pressure sensing module, and the power component on the side of the circuit board facing away from the touch panel, and arranging the pressure sensing module on the bracket. In this way, the pressure sensing module can detect the deformation of the bracket to detect the pressure corresponding to the touch action on the touch panel. Thus, the circuit board can control the coil structure of the power component to be energized according to the pressure signal sensed by the pressure sensing module. As a result, the coil structure can generate a magnetic field when energized, enabling the magnet to drive the touch panel to vibrate under the action of the magnetic field, thereby achieving vibration feedback. It can be seen that for the touchpad of the present application, by arranging the bracket, the pressure sensing module, and the power component on the side of the circuit board facing away from the touch panel, the space of the circuit board can be reasonably utilized, making the overall structure of the touchpad more compact and facilitating the miniaturized design of the touchpad.

[0031] In addition, in the touchpad of the present application, since the power component is directly arranged on the circuit board, the vibration transmission loss can be reduced, making the vibration feedback more direct and effective. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0045] The terms "installation", "arrangement", "provided with", "connection", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0046] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0047] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0048] Please refer to Figures 1 to 3 , the present application also discloses a touchpad 100, which includes a circuit board 10, a touch panel 20, a pressure sensing module 30, a bracket 40 and a power component 50. Among them, the touch panel 20 can be arranged on one side of the circuit board 10, and the touch panel 20 is configured to be touchable by a user to generate corresponding touch information according to the user's touch action. The bracket 40 can be elastically connected to the side of the circuit board 10 facing away from the touch panel 20, and the bracket 40 is located on the side of the circuit board 10 facing away from the touch panel 20. The pressure sensing module 30 is arranged on the bracket 40 and electrically connected to the circuit board 10. The power component 50 is arranged on the side of the circuit board 10 facing away from the touch panel 20, and the power component 50 includes a coil structure 51 (see Figure 5 ), and a magnet 52 (see Figure 5 ), the coil structure 51 is electrically connected to the circuit board 10, and the coil structure 51 is configured to generate a magnetic field when energized, so that the magnet 52 drives the touch panel 20 to vibrate under the action of the magnetic field.

[0049] In the touchpad 100 disclosed in the present application, through the settings of the bracket 40, the power component 50 and the pressure sensing module 30, at least part of the bracket 40 can be configured to be deformable along the thickness direction Z of the circuit board 10 in response to a touch action, so that the pressure sensing module 30 can detect the deformation and generate a pressure signal. Correspondingly, the circuit board 10 can pass a current to the coil structure 51 of the power component 50 according to the pressure signal, so that the coil structure 51 generates a magnetic field to drive the touch panel 20 to vibrate under the action of the magnetic field. It can be seen that by arranging the bracket 40, the pressure sensing module 30 and the power component 50 on the side of the circuit board 10 facing away from the touch panel 20, the space of the circuit board 10 can be reasonably utilized, making the overall structure of the touchpad 100 more compact, which is further beneficial to realizing the miniaturized design of the touchpad 100. In addition, in the touchpad 100 of the present application, the power component 50 is directly arranged on the circuit board 10, so that the vibration transmission loss can be reduced, making the vibration feedback more direct and effective.

[0050] It can be understood that the touch panel 20, the pressure sensing module 30, the power component 50, and the bracket 40 are respectively disposed on two opposite sides of the circuit board 10. This is because when the touchpad 100 is applied to an electronic device 200 (such as a laptop computer, a personal digital assistant, etc.), the touch panel 20 is actually exposed outside the electronic device 200, so as to be accessible for user touch. While the pressure sensing module 30, the power component 50, and the bracket 40 are located inside the electronic device 200, which not only makes the appearance of the touchpad 100 neat, but also facilitates the waterproof and dustproof design of the pressure sensing module 30, the power component 50, and the bracket 40.

[0051] It can be understood that the bracket 40 being elastically connected to the side of the circuit board 10 facing away from the touch panel 20 means that the bracket 40 can be connected to the side of the circuit board 10 facing away from the touchpad 100 through, for example, an elastic member. Thus, by utilizing the elastic effect of the elastic member, when the touch panel 20 is subjected to a touch action, at least a part of the bracket 40 can deform in response to the touch action, so that the pressure sensing module 30 disposed on the bracket 40 can sense the deformation and send a pressure signal to the circuit board 10.

[0052] It can be understood that when the pressure sensing module 30 detects the deformation of the bracket 40, since the pressure sensing module 30 is electrically connected to the circuit board 10, the pressure sensing module 30 can generate a pressure signal and send it to the circuit board 10. Then, the circuit board 10 can control the coil structure 51 to be energized according to the pressure signal, so that the coil structure 51 can generate a magnetic field with the magnet 52, and then drive the touch panel 20 to vibrate. That is to say, when the pressure sensing module 30 senses the pressure corresponding to a touch action, the power component 50 can be used to drive the touch panel 20 to vibrate to achieve vibration feedback. In this way, after the user touches the touch panel 20, a vibration feedback can be obtained quickly, with timely feedback and good feedback experience.

[0053] Considering that the pressure sensing module 30, the power component 50, and the bracket 40 are all disposed on the circuit board 10, this is not conducive to the arrangement of other electronic devices on the circuit board 10. Based on this, in some embodiments, the circuit board 10 may include a first board body 11 and a second board body 12, and the first board body 11 and the second board body 12 may be sequentially arranged along their own thickness directions. The touch panel 20 may be disposed on one side of the first board body 11, and the bracket 40, the power component 50, and the pressure sensing module 30 are all disposed on the side of the first board body 11 facing away from the touch panel 20. The second board body 12 may be located on the side of the bracket 40 facing away from the first board body 11, and the second board body 12 may be electrically connected to the first board body 11. The second board body 12 may be configured to arrange electronic devices. In this way, dividing the circuit board 10 into the first board body 11 and the second board body 12 can arrange all the electronic devices on the second board body 12. Compared with the design that requires increasing the overall size of the circuit board 10 (for example, the width, length, and thickness may all increase) when using a complete circuit board 10, the split-board type can make the overall sizes of both the first board body 11 and the second board body 12 (such as length, width, thickness, etc.) can be set smaller, thereby enabling the miniaturized design of the touchpad 100. In addition, the split-board type can also separate the arrangement of electronic devices from the arrangement of devices such as pressure feedback and vibration feedback without interference, thereby further facilitating the component layout of the touchpad 100.

[0054] It can be understood that the sizes of the first board body 11 and the second board body 12 may be the same or different, and can be specifically determined according to the actual electronic devices to be arranged and the above-mentioned devices such as vibration feedback and pressure feedback. This embodiment does not make specific limitations on this. Theoretically speaking, since there are relatively more electronic devices to be arranged, in actual settings, the size of the second board body 12 can be set slightly larger.

[0055] It can be understood that since the power component 50 and the bracket 40 are both disposed on the first board body 11, when the bracket 40 responds to the magnetic force generated by the power component 50, it will drive the first board body 11 to vibrate. Based on this, in order to prevent the second board body 12 from vibrating together during vibration, along the thickness direction Z of the first board body 11, the second board body 12 and the first board body 11 may be spaced apart, and the distance between the two can be determined according to the installation space of the touchpad 100 in the electronic device 200. This embodiment does not make specific limitations on this.

[0056] Optionally, the electrical connection between the first board body 11 and the second board body 12 can be achieved by additionally adding a flexible circuit board (not labeled) in combination with a connector. And the pressure sensing module 30 can be electrically connected to the second board body 12, thereby reducing the space occupation of the first board body 11, which will be described in detail below.

[0057] Please combineFigure 4 and Figure 5 As shown in Figure 5 , the pressure sensing module 30 can be deformed under the pressure applied when the user's finger presses the touch panel 20, so that the pressure sensing module 30 outputs a corresponding pressure signal. Among them, there can be various types of the pressure sensing module 30. For example, resistive sensors such as metal strain gauges or polymer materials, semiconductor strain gauge pressure sensing modules, inductive pressure sensing modules, capacitive pressure sensing modules, etc. Exemplarily, the pressure sensing module 30 is a piezoresistive pressure sensing module. When the pressure sensing module 30 is deformed under pressure, its own impedance will change accordingly. The piezoresistive pressure sensing module has a simple structure and high sensitivity. The piezoresistive pressure sensing module includes four variable resistors, and the four variable resistors are interconnected to form a Wheatstone bridge detection circuit. Through this detection circuit, the resistance change is converted into a corresponding electrical signal (voltage or current) and output, thereby completing the process of converting pressure into an electrical signal.

[0058] In some embodiments, the pressure sensing module 30 includes a pressure sensor 31 and a flexible circuit board 32 that are electrically connected to each other. The flexible circuit board 32 is disposed on the bracket 40 and located between the bracket 40 and the first plate body 11. That is to say, along the thickness direction Z of the circuit board 10, the flexible circuit board 32 is located between the bracket 40 and the first plate body 11. In this way, the bracket 40 can be used to support the flexible circuit board 32 without adding additional reinforcement for the flexible circuit board 32, which is beneficial to simplifying the structural design of the touchpad 100.

[0059] Furthermore, the pressure sensor 31 is disposed on the flexible circuit board 32 and located between the flexible circuit board 32 and the bracket 40, so that the pressure sensor 31 can be electrically connected to the second plate body 12 through the flexible circuit board 32, realizing signal interaction between the pressure sensor 31 and the circuit board 10.

[0060] Optionally, the pressure sensor 31 can be set to multiple, and the multiple pressure sensors 31 can be evenly disposed on the first plate body 11. By setting multiple pressure sensors 31, no matter where the user presses the touchpad 100, it can be sensed, and the pressure sensing effect is better. At the same time, the pressure detection accuracy of the touchpad 100 is higher. Exemplarily, the pressure sensor 31 can be set to two, three, four, six or more, etc., and can be specifically set according to actual situations.

[0061] Optionally, when the multiple pressure sensors 31 are arranged, they can be symmetrically arranged relative to the center of the first plate body 11. In this way, the arrangement of the pressure sensors 31 is more uniform. Furthermore, when the user's touch action acts on the touch panel 20, the pressure sensors 31 sense the touch action more stably and evenly, avoiding the occurrence of uneven sensing.

[0062] The flexible circuit board 32 includes a first flexible portion 32a, a second flexible portion 32b, and a third flexible portion 32c. The first flexible portion 32a and the second flexible portion 32b are arranged facing each other. Some of the pressure sensors 31 can be disposed on the first flexible portion 32a, and the other pressure sensors 31 can be disposed on the second flexible portion 32b, so that the arrangement of the plurality of pressure sensors 31 is more uniform. The third flexible portion 32c can be connected between the first flexible portion 32a and the second flexible portion 32b, and the third flexible portion 32c is electrically connected to the second board body 12. The flexible circuit board 32 adopting the design including the first flexible portion 32a, the second flexible portion 32b, and the third flexible portion 32c can realize the simultaneous connection of the plurality of pressure sensors 31 and can also realize the unified electrical connection of the plurality of pressure sensors 31 to the second board body 12, making the electrical connection mode between the pressure sensor 31 and the second board body 12 simpler.

[0063] Exemplarily, the first board body 11 is substantially a rectangular board, and the first board body 11 has four corners, and the pressure sensors 31 are provided at all four corners. That is, there are four pressure sensors 31, which are respectively disposed at the four corners of the first board body 11. In this way, two pressure sensors 31 at one end of the first board body 11 can be disposed on the first flexible portion 32a, and the two pressure sensors 31 at the other end of the first board body 11 can be disposed on the second flexible portion 32b. That is to say, the first flexible portion 32a and the second flexible portion 32b can be substantially formed into an I-shaped plate, and the two pressure sensors 31 are disposed at both ends of the first flexible portion 32a, and the third flexible portion 32c is substantially connected to the middle parts of the first flexible portion 32a and the second flexible portion 32b, so as to avoid interference with the pressure sensors 31. In addition, considering that the third flexible portion 32c needs to realize the electrical connection with the second board body 12, therefore, the third flexible portion 32c can also extend an extension portion 320 at its own middle part, and the extension portion 320 can be used to extend to the second board body 12 to realize the electrical connection with the second board body 12.

[0064] It can be understood that, as other examples, the pressure sensors 31 can also be six, four of which are disposed at the four corners of the first board body 11, and the remaining two can be respectively disposed at the middle parts of the two long sides of the first board body 11. That is to say, the pressure sensors 31 at the corners of the first board body 11 can be disposed on the first flexible portion 32a and the second flexible portion 32b, and the two pressure sensors 31 at the middle parts of the long sides of the first board body 11 can be disposed on the third flexible portion 32c.

[0065] Optionally, the bracket 40 can be, for example, a stainless steel sheet, a silicon steel sheet, or a permanent magnet sheet, etc., so that the bracket 40 can vibrate in response to the action of the magnetic force. At the same time, the bracket 40 adopts a sheet structure. On the one hand, it is to more easily deform in the thickness direction of the first plate body 11 in response to a touch action and deform in response to the action of the magnetic force. On the other hand, it is to make the overall structure of the touch panel 100 thinner and lighter while the bracket 40 has a certain structural strength.

[0066] As can be seen from the foregoing, the bracket 40 is elastically connected to the first plate body 11. Therefore, the bracket 40 can be connected to the first plate body 11 through an elastic member 401 to realize deformation in response to a touch action. Exemplarily, the bracket 40 can be connected to the first plate body 11 through an elastic member 401 such as a silica gel member, a rubber member, or a spring piece. Taking the elastic member 401 as a silica gel member as an example, the silica gel member can be bonded to the first plate body 11 by, for example, an adhesive, and the bracket 40 is also bonded to the silica gel member by an adhesive. In this way, when the touch panel 20 is touched, the silica gel member can deform in the thickness direction Z of the first plate body 11 in response to the touch action. And since the pressure sensing module 30 is also provided on the bracket 40, when the touch panel 20 is touched, the pressure sensing module 30 can detect the deformation of the bracket 40, thereby generating a pressure signal and sending it to the circuit board 10. Furthermore, the circuit board 10 can control the coil structure 51 to be energized to generate a magnetic field according to the pressure signal so that the magnet 52 drives the touch panel 20 to vibrate under the action of the magnetic field.

[0067] Considering that the bracket 40 is used to support the flexible circuit board 32 and the pressure sensor 31, and the bracket 40 can realize pressure feedback, therefore, the bracket 40 can include a connecting portion 41a and a cantilever portion 41b. The connecting portion 41a is configured to be firmly connected to the housing of the electronic device, and the cantilever portion 41b is elastically connected to the circuit board. Thus, by including the cantilever portion 41b in the bracket 40 and the cantilever portion 41b being elastically connected to the first plate body 11, it can be realized that when the touch panel 20 is touched, the cantilever portion 41b can deform in the thickness direction Z of the first plate body 11 in response to the touch action.

[0068] In addition, the setting of the connecting portion 41a can fix the touch panel 100 to the housing of the electronic device by using the bracket 40, so that the fixation and support of the touch panel 100 can be realized without occupying the space of the circuit board.

[0069] Optionally, the bracket 40 may include a first arm 41, a second arm 42, and a third arm 43. The first arm 41 and the second arm 42 are arranged facing each other, and the third arm 43 is connected between the first arm 41 and the second arm 42. The first arm 41 and the second arm 42 both include the above-mentioned connecting portion 41a and the cantilever portion 41b, and the third arm 43 is connected to the connecting portions of the first arm 41 and the second arm 42. The bracket 40 has at least two connecting portions 41a and cantilever portions 41b, so that on the one hand, the force is more balanced when the bracket 40 is fixed to the electronic device; on the other hand, the bracket 40 can also respond more evenly to the touch action of the touch panel 20.

[0070] Optionally, as can be seen from the foregoing, the bracket 40 can be used to support the pressure sensing module 30. Based on this, when supporting the flexible circuit board 32, the first flexible portion 32a can be correspondingly arranged on the first arm 41, the second flexible portion 32b can be correspondingly arranged on the second arm 42, and the third flexible portion 32c is at least partially arranged on the third arm 43. In other words, the structures of the first arm 41 and the second arm 42 are generally adapted to the first flexible portion 32a and the second flexible portion 32b, that is, the first arm 41 and the second arm 42 are also generally formed in an I-shaped sheet, so as to better support the first flexible portion 32a and the second flexible portion 32b.

[0071] It can be seen that the bracket 40 can not only be deformed for the pressure sensor 31 to detect and generate a pressure signal, but also fix the touch panel 100 to the housing of the electronic device. In addition, the bracket 40 can also support and reinforce the flexible circuit board 32 of the pressure sensing module 30, so that there is no need to additionally reinforce the flexible circuit board 32. That is, the bracket 40 has multiple functions, reduces the components of the touch panel 100, and is beneficial to the miniaturization design of the touch panel 100.

[0072] Optionally, the first arm 41, the second arm 42, and the third arm 43 can enclose a power space 110 on the first plate body 11. Thus, the power component 50 can be located in the power space 110, and the power component 50 and the third arm 43 have a spacing in the width direction Y of the first plate body 11. In this way, it is possible to better realize the reasonable use of the space of the first plate body 11, and make the arrangement of the bracket 40 and the power component 50 on the first plate body 11 more compact. At the same time, it can also make the third arm 43 have enough deformation space.

[0073] Further, the coil structure 51 of the power component 50 is fixed to the circuit board. In one example, the third arm 43 can also be configured as a magnet to drive the touch panel 20 to vibrate. That is, at this time, the bracket 40 should be made of a magnetic material, such as metallic iron or a stainless steel bracket.

[0074] It can be understood that the third arm 43 should be arranged corresponding to the winding direction of the coil structure 51. Thus, when the coil structure 51 is energized to generate a magnetic field, the third arm 43 can be deformed to drive the touch panel 20 to vibrate under the action of the magnetic field, so as to achieve vibration feedback.

[0075] In another example, when the coil structure 51 is fixed on the circuit board 10, the magnet 52 can be arranged on the third arm 43. Similarly, the magnet 52 is arranged corresponding to the winding direction of the coil structure 51.

[0076] As can be seen from the foregoing, the third flexible portion 32c is generally connected to the middle portions of the first flexible portion 32a and the second flexible portion 32b. Correspondingly, the third arm 43 is also generally connected to the middle positions of the first arm 41 and the second arm 42. In this way, the space of the power space 110 enclosed by the first arm 41, the second arm 42 and the third arm 43 is relatively limited, which may not be conducive to the arrangement of the power component 50. Based on this, exemplarily, the third flexible portion 32c can be at least partially bent in the direction toward the first plate body 11. Thus, correspondingly, the third arm 43 is also bent in the direction toward the first plate body 11. For example, as Figure 4 shown, taking the side upward in the paper plane direction of the figure as the first side 11a of the first plate body 11 and the side downward in the paper plane direction of the figure as the second side 11b of the first plate body 11, then, the third flexible portion 32c and the third arm 43 can both be bent from the first side 11a to the second side 11b, so that the third flexible portion 32c and the third arm 43 are both closer to the edge of the second side 11b. In this way, the space of the power space 110 formed by enclosing the first arm 41, the second arm 42 and the third arm 43 is larger, which is more conducive to the arrangement of the power component 50.

[0077] Optionally, the first arm 41 and the second arm 42 each include two cantilever portions 41b and a connecting portion 41a. The two cantilever portions 41b are respectively connected to both ends of the connecting portion 41a. In this way, it is equivalent that the bracket 40 includes four cantilever portions 41b and two connecting portions 41a. Thus, the four cantilever portions 41b are arranged in pairs facing each other, which can further make the bracket respond more evenly to the touch action of the touch panel 20.

[0078] Further, as described above, there may be four pressure sensors 31. Therefore, the four pressure sensors 31 can be correspondingly disposed on the four cantilever portions 41b, so as to better sense the deformation of the cantilever portions 41b.

[0079] Please also refer to Figures 3 to 5 As shown, optionally, as described above, the pressure sensor 31 can be disposed at the corner of the first plate body 11. Correspondingly, at least a part of the bracket 40 can also be disposed at the corner of the first plate body 11, and the power assembly 50 (coil structure 51 and magnet 52) can be disposed substantially in the middle of the first plate body 11. Such an arrangement can reasonably utilize the space of the first plate body 11, making the overall structure of the touch panel 100 more compact, which is beneficial to the miniaturization and thinning design of the touch panel 100. In addition, pressure detection can be realized at the corners of the circuit board 10, and vibration feedback can be realized in the middle of the circuit board 10. That is to say, no matter where the user touches the touch panel 20, corresponding vibration feedback can be obtained, so as to realize the full-area feedback of the touch panel 20. That is, the touch panel 100 is formed into a full-area touch panel 100, and the touch feedback experience is better, which is beneficial to improving the user experience.

[0080] In actual setting, the first plate body 11 can be substantially in the shape of a rectangular plate. The first arm 41 and the second arm 42 of the bracket 40 can be disposed at both ends of the first plate body 11 along the length direction X. That is, the magnet 52 is located between the first arm 41 and the second arm 42 and is spaced from the first arm 41 and the second arm 42. Thus, the third arm 43 can be deformed under the action of the magnetic field generated by the coil structure 51, so as to drive the first plate body 11 and the touch panel 20 thereon to vibrate as a whole to provide vibration feedback. The structural design of the vibration feedback in the present application is simple, small in volume, and small in installation space occupation, and can be applied to relatively thin and light electronic devices 200. At the same time, since the coil structure 51, the magnet 52, and the touch panel 20 are all directly disposed on the first plate body 11, the delay of the vibration force transmitted by the intermediate components is reduced, and the response speed of the vibration feedback is faster.

[0081] Optionally, there may be a plurality of coil structures 51, and the plurality of coil structures 51 can be spaced apart in the power space 110 of the first plate body 11. By providing a plurality of coil structures 51, the generated magnetic force can be increased, so that the intensity of the vibration feedback is greater and it is easier to be perceived by the user. Exemplarily, the coil structure 51 can be two, three, four or more, and can be specifically set according to actual situations, and the present embodiment does not make specific limitations thereto.

[0082] Optionally, the coil structure 51 may include a winding portion 51a (i.e., the coil portion) and a fixing portion 51b connected to the winding portion 51a. Each winding portion 51a is respectively wound around a corresponding fixing portion 51b, and the fixing portions 51b of two adjacent coil structures 51 are connected together. Moreover, the fixing portion 51b is configured to be fixedly connected to the first plate body 11. By connecting multiple fixing portions 51b together, the directions of the magnetic fields generated by multiple coil structures 51 can be made consistent, so that the touch panel 20 can be driven to vibrate better.

[0083] In addition, by fixing the fixing portion 51b on the first plate body 11, the fixing of the coil structure 51 on the first plate body 11 can be realized, so that the fixing manner of the coil structure 51 on the first plate body 11 is simple and reliable.

[0084] It can be understood that the multiple fixing portions 51b can be integrally provided, and the fixing portion 51b extends along the length direction X of the first plate body 11, while the winding portion 51a is substantially perpendicular to the fixing portion 51b, that is, the winding portion 51a extends substantially along the width direction Y of the first plate body 11. In this way, the winding portion 51a can have sufficient winding space. At the same time, the fixing portion 51b can also have sufficient fixing space and space the two adjacent coil structures 51 apart, so that the two adjacent coil structures 51 do not interfere with each other.

[0085] Optionally, the fixing portion 51b may be a sheet-like structure. The fixing portion 51b in the sheet-like structure can be thinner and lighter. When the winding portion 51a is wound around the fixing portion 51b, the overall coil structure 51 formed after winding is thinner and lighter, which is beneficial to the thin and light design of the touch pad 100. Exemplarily, the fixing portion 51b may be a silicon steel sheet, a stainless steel sheet or a permanent magnet sheet, etc., so that the fixing portion 51b can also respond to the magnetic field and obtain a magnetization intensity, which is beneficial to improving the utilization rate of the generated magnetic field energy. The fixing portion 51b may be substantially in a T-shaped sheet.

[0086] In a second aspect, please refer to Figure 6 and Figure 7 , the present application also discloses an electronic device 200, which includes a housing 201 and the touch pad 100 as described in the second aspect above. Wherein, an installation groove (not shown) is provided on the housing 201, the touch pad 100 is installed in the installation groove, and the touch panel 20 of the touch pad 100 can cover the opening of the installation groove to be at least partially exposed in the installation groove, so as to facilitate the user to touch the touch panel 20.

[0087] It can be understood that the above-mentioned electronic device 200 may include but is not limited to, for example, a laptop computer, a handheld game console, etc.

[0088] The electronic device 200 with the touchpad 100 can also achieve comprehensive vibration feedback, providing a better user experience, and can also achieve a miniaturized and thinner design of the electronic device 200.

[0089] It should be noted that Figure 6 only the example where the touchpad 100 is disposed on the right side of the housing 201 of the electronic device 200 ( Figure 6 in the paper plane direction) is given. However, the position of the touchpad 100 on the housing 201 can be set according to actual situations. For example, the touchpad 100 can be disposed in the middle of the housing 201, or can be disposed on the left side of the housing 201, or can be disposed on the upper side or the lower side of the housing 201, etc. This embodiment does not make specific limitations thereto.
