Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

A touch pad is an input device for controlling a screen cursor applied to an electronic device. The touch pad obtains touch information such as high-resolution finger coordinates by detecting small capacitance changes of fingers of a user during operation in a panel area so as to accurately control a screen cursor to move and click. Usually, a single key is also configured on the back of the touch pad, and the functions of the left key and the right key of the traditional mouse are realized by detecting the behavior of the key.

In order to improve the operation convenience of the touch pad, the pressure touch pad is gradually becoming a new trend. The pressure touch pad is characterized in that a physical key of a conventional touch pad is eliminated, and pressure induction and vibration feedback functions are added.

A pressure touch panel of an electronic device is generally composed of a touch panel, a pressure sensor, a tactile feedback member, a metal reinforcing plate, a metal elastic support, and the like. The touch feedback component needs to be placed at the right center position below the touch panel, so that any area of the touch panel contacted by a finger can feel the same vibration experience in actual experience.

However, in the actual whole machine stacking design process, most of the parts under the pressure touch panel are battery assemblies and main boards. The battery cell can bulge in the charging and discharging process, the whole machine is stacked without too much safety space, the metal object of the tactile feedback component is prevented from contacting the battery cell to cause safety accidents due to piercing, and the placement position of the tactile feedback component is offset under the common condition. For example, the haptic feedback component may be placed between a plastic frame of the battery package and the touch pad, or between the motherboard and the touch pad.

The offset of the haptic feedback elements can cause inconsistent vibration.

In view of this, embodiments of the present application provide a touch pad, which is beneficial to solve the problem of inconsistent vibration after the haptic feedback component is biased.

It should be understood that the technical solutions of the embodiments of the present application can be applied to various electronic devices.

Such as portable or mobile computing devices, e.g., smart phones, laptops, tablets, gaming devices, etc., and other electronic devices, e.g., electronic databases, automobiles, Automated Teller Machines (ATMs), etc. However, the embodiments of the present application do not limit this.

Fig. 1 shows a schematic exploded view of a touch panel 100 according to an embodiment of the present application. For the sake of convenience of embodying the details of the support plate, the touch panel in fig. 1 is located below the support plate, but it should be noted that "up" and "down" described below are the positional relationship embodied by standing at the user's angle, that is, for the user, the touch panel is located at the uppermost position of the touch pad. Specifically, as shown in fig. 1, the touch pad 100 includes:

a touch panel 110;

a tactile feedback part 120 disposed below the touch panel 110 for providing a vibration feedback to a user;

the supporting plate 130 is disposed below the touch panel 110, the supporting plate 130 includes a reinforcing region 131, a fastening region 132 and four flexible connecting arms 133, the reinforcing region 131 is connected to the fastening region 132 through the flexible connecting arms 133, the reinforcing region 131 is fixedly connected to the touch panel 110, the fastening region 132 is used for being fixedly connected to a chassis of an electronic device, a gap is formed between the flexible connecting arms 133 and the touch panel 110, and the four flexible connecting arms 133 are used for balancing vibrations of the haptic feedback component 120.

As shown in FIG. 1, the four flexible attachment arms 133 may include flexible attachment arm 1331, flexible attachment arm 1332, flexible attachment arm 1333, and flexible attachment arm 1334, respectively. The four flexible connecting arms 133 are symmetrically disposed at four corners of the supporting plate 130. That is, the flexible connecting arm 1331 and the flexible connecting arm 1332, and the flexible connecting arm 1333 and the flexible connecting arm 1334 are axially symmetric in the first direction X. Flexible connecting arm 1331 and flexible connecting arm 1334, and flexible connecting arm 1332 and flexible connecting arm 1333 are axially symmetric in the second direction Y.

It should be noted that the tactile feedback unit 120 in the embodiment of the present application may provide vibration feedback to the user based on the pressure signal detected by the pressure sensor, and the tactile feedback unit 120 may also provide vibration feedback to the user based on other signals, for example, based on the touch signal detected by the touch panel. Although the following description refers to embodiments combining pressure sensing and tactile feedback, it should be understood that the embodiments of the present application do not limit the type of input signal of the tactile feedback component 120.

Specifically, in the embodiment of the present application, the supporting plate 130 is used for supporting the touch panel 110, and should have a certain strength, so the supporting plate 130 can also be referred to as a reinforcing plate. The supporting plate 130 may include a reinforcing region 131 and a fastening region 132, where the reinforcing region 131 refers to a partial region of the supporting plate 130 for supporting the touch panel 110, that is, the reinforcing region 131 is fixedly connected to the lower surface of the touch panel 110. For example, the reinforcing region 131 may be adhered to the lower surface of the touch panel 110. The fastening area 132 refers to a partial area of the support plate 130 where the support plate 130 is mounted to the electronic device, for example, the fastening area 132 may connect the support plate 130 to a housing of the electronic device. The supporting plate 130 further comprises a flexible connecting arm 133, and the reinforcing region 131 and the fastening region 132 are connected by the flexible connecting arm 133, i.e. the reinforcing region 131 and the fastening region 132 are flexibly connected. The flexible connection may also be referred to as a flexible connection, and thus the flexible connecting arms 133 may also be referred to as flexible arms. The flexible connecting arms 133 in the embodiment of the present application have both a relation of restraining or transmitting vibration and a certain degree of relative displacement. I.e., there is a gap between the flexible link arms 133 and the lower surface of the touch panel 110. When the haptic feedback element 120 vibrates, the flexible link arms 133 may vibrate up and down within the gap, thereby balancing the vibration of the haptic feedback element 120.

Therefore, in the touch panel of the embodiment of the present application, the reinforcing region 131 and the fastening region 132 of the supporting plate 130 are integrally connected by the flexible connecting arm 133, so that the assembly process of the touch panel 100 can be simplified. And when the tactile feedback part 120 vibrates, the vibration can be transmitted through the relative displacement of the flexible connecting arms 133, and because the four flexible connecting arms 133 are symmetrically arranged at the four corners of the supporting plate 130, the vibration generated by the tactile feedback part 120 can be uniformly distributed at each position of the touch panel, so that the problem of inconsistent vibration when the tactile feedback part 120 is biased can be solved, and the vibration experience of a user can be improved.

In addition, the flexible connecting arms 133 are disposed at the corners of the supporting board 130, so as to increase the area of the reinforcing region 131 as much as possible, thereby solving the problem of inconsistent vibration when the tactile feedback member 120 is biased without affecting the rigidity of the touch pad 100.

Optionally, in an embodiment of the present application, the aspect ratio of the flexible connecting arms is greater than or equal to 10: 1.

Fig. 2 is a schematic enlarged view of a portion a in fig. 1. As shown in FIG. 2, the flexible connecting arms 133 include a main body portion 1337, a first connecting portion 1335 and a second connecting portion 1336. Both ends of the main body portion 1337 are connected to one end of a first connection portion 1335 and one end of a second connection portion 1336, respectively, the other end of the first connection portion 1335 is connected to the reinforcement region 131, and the other end of the second connection portion 1336 is connected to the fastening region 132. The length of the flexible connecting arm 133 referred to herein is the length of the main body portion 1337 after being straightened, and the lengths of the first connecting portion 1335 and the second connecting portion 1336 are negligible, that is, the total length of the line segment from arrow 1 to arrow 2 in fig. 2. The width of the flexible connecting arm 133 is the width of the main body part 1337, i.e. the length of the dotted line from arrow 3 to arrow 4 in fig. 2.

The length-width ratio of the flexible connecting arm is set to be larger than or equal to 10:1, so that the vibration trailing time (or braking time) of the tactile feedback component can be effectively shortened, and the vibration experience is more crisp.

Optionally, in this embodiment, the width of the flexible connecting arm is greater than or equal to 2 mm.

Setting the width of the flexible connecting arm 133 to be greater than or equal to 2mm can enhance the connection strength between the flexible connecting arm 133 and the reinforcing region 131 or the fastening region 132, so that the connection is not easily broken.

The reinforcing region 131 and the fastening region 132 have a through hole 135 therebetween. As shown in fig. 5, a projection area of the fastening region 132 onto a plane of the touch panel is located in the touch panel (not shown in the figure, located right above the supporting plate 130, and covering the whole supporting plate 130), and the fastening region 132 is disposed outside two opposite sides of the reinforcing region 131, for example, outside two sides of the reinforcing region 131 extending along the first direction X. Two of the four flexible link arms 133 that are located outside of the same side of the reinforcing region are connected together by the fastening region 132. For example, in FIG. 5, arm 1331 and arm 1332 are attached by fastening region 132, and arm 1333 and arm 1334 are attached by fastening region 132.

Fig. 6 shows a further schematic top view of the support plate 130 provided in the embodiments of the present application.

As shown in fig. 6, the projection area of the fastening area 132 onto the plane of the touch panel is disposed outside two opposite sides of the touch panel (not shown in the figure, and located right above the area surrounded by the dotted line in the figure), for example, outside two sides of the touch panel extending in the first direction X. Two of the four flexible link arms 133 that are located outside of the same side of the touch panel are connected together by the fastening region 132. For example, in FIG. 6, flexible attachment arm 1331 and flexible attachment arm 1332 are connected together by fastening region 132, and flexible attachment arm 1333 and flexible attachment arm 1334 are connected together by fastening region 132.

Fig. 7 shows another schematic top view of the support plate 130 provided by the embodiment of the present application. As shown in FIG. 7, the supporting plate 130 includes a reinforcing region 131, a fastening region 132, and four flexible connecting arms 133 (flexible connecting arm 1331, flexible connecting arm 1332, flexible connecting arm 1333 and flexible connecting arm 1334), and the four flexible connecting arms 133 are symmetrically distributed at four corners of the supporting plate 130. As shown in fig. 7, the projected areas of the fastening areas 132 projected onto the plane of the touch panel are located at four corners of the touch panel, and the four flexible connecting arms 133 are independent from each other.

Although in the above embodiments, the supporting plate 130 is provided with four flexible connecting arms 133, it is understood by those skilled in the art that the number of the flexible connecting arms 133 is not limited in the embodiments of the present application. For example, the support plate 130 includes six flexible connection arms, and the six flexible connection arms may be symmetrically arranged at four corners of the support plate 130 and at central positions of two sides of the support plate 130 extending in the first direction X.

As shown in fig. 8 and 9 (an enlarged schematic view of a portion B in fig. 8), after the supporting plate 130 is assembled with the touch panel 110 and the chassis of the electronic device, respectively, the flexible connecting arm 133 and the touch panel 110 have a gap H in the third direction Z. The gap H forms a space for deformation of the flexible connecting arm 133 in the Z-axis. That is, when the haptic feedback member 120 vibrates, the flexible connecting arms 133 are relatively displaced between the gaps H along the third direction Z. As can also be seen, the gap H is also the vertical distance between the bonding surface of the reinforcing region 131 and the surface of the fastening region 132. Optionally, the size range of the gap H may be 0.2mm to 1mm, and further, the size range of the gap H is 0.6mm to 0.7mm, so that the vibration effect is better.

Fig. 10 shows another schematic exploded view of the touch panel 100 according to the embodiment of the present application.

Optionally, in this embodiment of the application, as shown in fig. 10, the touch pad 100 further includes: a pressure sensor 141 disposed below the touch panel 110 for converting a deformation of the pressure sensor 141 into an electrical signal when the touch panel 110 receives a pressure; the haptic feedback component 120 is configured to provide haptic feedback to the user based on the electrical signal.

In this embodiment, the tactile feedback part 120 may vibrate the touch panel 110 according to the electric signal detected by the pressure sensor 141, and feedback the vibration to the user. The vibratory feedback may enable the user to determine whether their pressing operation is effective, thereby minimizing repetitive gestures.

Specifically, the haptic feedback part 120 may bring the touch panel 110 to vibrate together when the electric signal detected by the pressure sensor 141 is greater than the first threshold value. The first threshold is a specified threshold, which may be empirically derived. The first threshold may refer to a critical value of a pressing force at which the user can perceive the shock, and may be greater than 0.

Alternatively, when the touch pad 100 is applied to an electronic device, the electronic device may store a plurality of threshold values of the pressing force, and the user may select one of the threshold values according to the usage habit. For example, the electronic device stores a critical value of light pressing, a critical value of medium pressing, and a critical value of heavy pressing, and the user can select one of the critical values according to the degree of pressing to which the user is accustomed.

Alternatively, as shown in fig. 10, the pressure sensor 141 may be electrically connected to the touch panel 110 through a Flexible Printed Circuit (FPC) 142 of the pressure sensor. That is, the electric signal detected by the pressure sensor 141 may be transmitted to the circuit board of the touch panel 110 through the FPC 142 of the pressure sensor, and the circuit board of the touch panel 110 may drive the haptic feedback member 120 to generate vibration.

Optionally, in the embodiment of the present application, as shown in fig. 3 to 7 and fig. 10, the supporting board 130 is further provided with a cantilever beam structure 134, and the cantilever beam structure 134 can be used for supporting the pressure sensor 141 and bringing the pressure sensor 141 into deformation when the touch panel 110 is subjected to a pressure.

The cantilever beam structure 134 refers to the reinforcing region 131 opposite to the support plate 130, which is suspended below the touch panel 110. That is, the cantilever beam structure 134 has a gap with the touch panel 110. For example, the lower surface of the cantilever structure 134 is flush with the lower surface of the reinforcing region 131, and the thickness of the cantilever structure 134 is smaller than the thickness of the reinforcing region 131, so that a gap is formed between the cantilever structure 134 and the touch panel 110. Optionally, the cantilever beam structure 134 is used to support the pressure sensor 141, it is understood that the pressure sensor 141 is fixed to the upper surface of the cantilever beam structure 134. Or the pressure sensor 141 may be affixed to the lower surface of the cantilever structure 134. Here, the lower surface refers to a surface away from the touch panel 110, and the upper surface refers to a surface close to the touch panel 110.

In this embodiment, the cantilever beam structure 134 for supporting the pressure sensor 141 and the stiffener for supporting the touch panel 110 are integrally formed, and an additional elastic support for supporting the pressure sensor 141 is not required, so that the number of components of the touch panel 100 is reduced, the assembly process is simplified, and the cost is saved.

Optionally, as shown in fig. 3 to 7, the support plate 130 is provided with four cantilever structures 134, including a cantilever structure 1341, a cantilever structure 1342, a cantilever structure 1343 and a cantilever structure 1344, and the four cantilever structures 134 are symmetrically distributed at four corners of the support plate 130.

Specifically, the four cantilever beam structures 134 and the four flexible connecting arms 133 may be disposed in pairs at four corners of the supporting plate 130.

In this embodiment, the cantilever structure 134 is disposed at each of four corners of the supporting board 130, so as to increase the structural stability of the touch pad. Secondly, the pressure sensors 141 are distributed at 4 corners of the support plate 130 through the cantilever beam structures 134, and the uniformity of pressure detection can be improved.

Those skilled in the art will appreciate that the number of cantilever beam structures 134 is not limited in the embodiments of the present application. For example, six cantilever beam structures may be provided to the support plate 130, and the six cantilever beam structures may be symmetrically arranged at four corners of the support plate 130 and at central positions of two sides of the support plate 130 extending in the first direction X. It should be noted that the number of the cantilever beam structures 134 and the number of the flexible connection arms 133 in the embodiment of the present application may be the same or different.

Alternatively, as shown in FIGS. 1-8 and 10, the arms 133 may be of a bent configuration.

By configuring the flexible arms 133 in a folded configuration, the aspect ratio of the flexible arms 133 can be greater than or equal to 10:1 while occupying as little area of the support plate 130 as possible that belongs to the reinforcement area 131.

Alternatively, the cantilevered beam structure 134 may extend from the fastening region 132 of the support plate 130, which is not directly connected to the reinforcing region 131, but indirectly connected thereto by the flexible connecting arm 133.

In one example, as shown in fig. 3 to 6, the cantilever beam structure 134 extends from the fastening region 132 to the reinforcing region 131 along the second direction Y, and the extending direction of the flexible connecting arm 133 is the same as the extending direction of the cantilever beam structure 134, the flexible connecting arm 133 is a bent structure, and a first fixed end of the bent structure is connected to the reinforcing region 131, and a second fixed end of the bent structure is connected to the fastening region 132. Taking flexible connection arm 1333 of fig. 3-6 as an example, flexible connection arm 1333 is a bent structure, a first fixed end 13331 of the bent structure is connected to reinforcing region 131, and a second fixed end 13332 of the bent structure is connected to fastening region 132.

In another example, as shown in fig. 7, the cantilever structure 134 extends from the fastening region 132 away from the reinforcing region 131 along a first direction X, the extending direction of the flexible connecting arm 133 is perpendicular to the extending direction of the cantilever structure 134, the flexible connecting arm 133 is a bent structure, a first fixed end of the bent structure is connected to a root of the cantilever structure 134, a second fixed end of the bent structure is connected to the reinforcing region 131, and the fastening region 132 is located at a connection position of the first fixed end and the root. Taking flexible connection arm 1334 of fig. 7 as an example, the flexible connection arm 1334 is a bent structure, a first fixed end 13341 of the bent structure is connected to the root of the cantilever structure 1344, and a second fixed end 13342 of the bent structure is connected to the reinforcing region 131. The fastening region 132 is located at the junction of the first fixed end 13341 and the root of the cantilevered beam structure 1344.

Optionally, the extension length of the flexible connecting arm 133 may not be greater than the extension length of the cantilever structure 134, so that the flexible connecting arm 133 occupies as little area of the supporting plate 130 belonging to the reinforcing area 131 as possible, the reinforcing area 131 of the supporting plate 130 is increased, and the rigidity of the touch pad 100 is further increased.

Alternatively, in other embodiments, the cantilever beam structure 134 may also extend from the reinforcing region 131 of the supporting plate 130, and the reinforcing region and the fastening region 132 are not directly connected, but indirectly connected through the flexible connecting arm 133.

Alternatively, in the case that the lower surface of the supporting plate 130 is a plane, the upper surface of the cantilever beam structure 134 may be flush with the upper surface of the flexible connecting arm 133, that is, the thickness of the cantilever beam structure 134 is the same as that of the flexible connecting arm 133. That is, the gap between the cantilever beam structure 134 and the touch panel 110 is the same as the gap between the flexible connecting arm 133 and the touch panel 110. In other examples, the cantilever beam structure 134 has a thickness different from the thickness of the flexible link arm 133, and as such, the lower surface is the surface away from the touch panel 110, and the upper surface is the surface close to the touch panel 110.

Optionally, in this embodiment of the application, as shown in fig. 10, the touch pad 100 further includes: the damping member 150 is disposed between the touch panel 110 and the cantilever beam structure 134, and is used for deforming the cantilever beam structure 134 when the touch panel 110 is subjected to a pressure.

Specifically, the damping member 150 may be disposed alongside the pressure sensor 141 on the upper surface of the cantilevered beam structure 134. And the damping member 150 can fill the gap between the upper surface of the cantilever beam structure 134 and the lower surface of the touch panel 110. When a finger presses the touch panel 110, the damping member 150 can deform the cantilever structure 134, so as to drive the pressure sensor 141 to deform.

In this embodiment, by disposing the damping component 150 between the cantilever structure 134 and the touch panel 110, the cantilever structure 134 can be deformed, so as to drive the pressure sensor 141 to be deformed, so that the pressure sensor performs pressure detection.

Alternatively, in one example, the damping member 150 may be a silicone composite material, such as a silicone pad. In other examples, the damping member 150 may be a spring.

The dampening device 150 may be used to not only deform the cantilever structure 134, but also absorb the aftershock generated by the tactile feedback device 120.

Optionally, the hardness of the damping member 150 may be selected to be between 20A and 30A shore hardness to ensure a certain rigidity of the damping member, so as to avoid the damping member itself from being strained when the touch panel 110 is subjected to a pressure, which affects the accuracy of pressure detection.

Optionally, the thickness of the damping component 150 may be set between 0.5mm and 0.8mm, which may avoid that the strain space of the cantilever structure 134 is insufficient due to an excessively small thickness of the damping component 150, and thus the pressure sensor supported by the cantilever structure 134 may not effectively perform pressure detection. The problem of inconsistent vibration of the touch panel due to the excessive thickness of the damping member 150 can be avoided.

Alternatively, in the present embodiment, the haptic feedback component 120 may be a linear motor, such as an X or Y axis vibrating linear motor. The haptic feedback component 120 may also be a piezoceramic wafer or the like. Alternatively, the haptic feedback component 120 may be another suitable actuator.

Optionally, as shown in FIG. 10, an avoidance region 136 may be provided on the support plate 130 to avoid the tactile feedback member 120.

Optionally, in this embodiment, the extending direction of the flexible connecting arm 133 is angled with respect to the vibration direction of the tactile feedback member 120.

As shown in fig. 3 to 7, the vibration direction of the haptic feedback part 120 is a first direction X, and the extending direction of the flexible connecting arms 133 is a second direction Y, i.e. the extending direction of the flexible connecting arms 133 is perpendicular to the vibration direction of the haptic feedback part 120. In other examples, the extending direction of the flexible connecting arms 133 is at an acute angle to the vibrating direction of the haptic feedback component 120.

It should be understood that the angle between the extending direction of the flexible connecting arms 133 and the vibration direction of the haptic feedback part 120 may not be limited in the embodiments of the present application, for example, if the vibration direction of the haptic feedback part 120 in fig. 3 to 7 is the second direction Y, the extending direction of the flexible connecting arms 133 is parallel to the vibration direction of the haptic feedback part 120.

Alternatively, as shown in fig. 10, the touch panel 110 may include: a protective panel 111, a Printed Circuit Board (PCB) 112, and a paste 113; the protection panel 111 and the PCB 112 may be adhered together by an adhesive 113.

Alternatively, the protective panel 111 may be used for user touch and pressure, or may be used as an appearance decoration, typically using glass or mylar (mylar). The PCB 112 can be used to process electrical signals obtained from various sensors within the touch pad 100. For example, the PCB 112 is used to output a driving signal to the haptic feedback part 120 according to a pressure signal detected by the pressure sensor 141.

Optionally, a component area 1120 is further disposed on the PCB 112, and correspondingly, the supporting plate 130 is disposed with an avoiding area 137 for avoiding the component area 1120.

Alternatively, the pressure sensor 141 in the embodiment of the present application may be a piezoresistive pressure sensor, and other types of pressure sensors may be used.

With continued reference to fig. 10, the support plate 130 may be adhered to the touch panel 110 by glue 160. Specifically, the reinforcing region 131 of the supporting plate 130 is bonded to the touch panel 110.

Alternatively, the glue 113 and the glue 160 in the embodiment of the present application may be double-sided glue, or flexible glue or glue pad.

Optionally, the housing is lockingly attached to the fastening region 132. Specifically, the fastening area 132 is provided with a fixing hole, and a mounting hole is provided at a corresponding position of the mounting surface of the housing, and the support plate 130 can be mounted on the housing of the electronic device by a fastening member, for example, a fastening nut, so as to fix the touch pad 100 on the housing of the electronic device.
