Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application. The embodiment of the application provides a touch device 100, which can be applied to electronic equipment as an input device of the electronic equipment, so that a user can input control signals to the electronic equipment through the touch device 100 to realize man-machine interaction operation between the user and the electronic equipment. The electronic device may be a notebook computer, a television, a palm tablet computer, etc., which is not limited in the embodiment of the present application.
As shown in fig. 1, the electronic device is a notebook computer. The notebook computer may further include a base 200, a display screen 300, and a keyboard 400. The display screen 300 may be rotatably mounted on the base 200. The base 200 is provided with a keyboard 400 as one of the input devices for the notebook computer to be operated by the user. It can be appreciated that, in the process of using the notebook computer, the user usually needs to use the mouse connected to the notebook computer to perform the operation, in order to improve the convenience of the notebook computer, a touch device 100 is generally disposed on the base 200, and the user can perform the same function as the mouse operation by operating on the touch device 100.
With continued reference to fig. 2 and 3, fig. 2 is a schematic structural diagram of a touch device of the electronic apparatus shown in fig. 1, and fig. 3 is a cross-sectional view of the touch device shown in fig. 2 along A-A direction. The touch device 100 may include a housing 11, a touch pad 12, an elastic support 13, and a pressure sensor. The housing 11 may be part of the outer shell of the base 200; housing 11 may also be formed of one or more separate pieces from base 200, and housing 11 and base 200 are fixedly connected. The elastic support 13 can elastically deform, one side of the elastic support 13 is fixedly connected with the shell 11, and the other side of the elastic support 13 is fixedly connected with the touch pad 12. The touch panel 12 is used to receive a touch signal from a user, such as by the touch panel 12 receiving a path of a user's finger swiped on the touch panel 12, and the notebook computer can correspondingly drive a cursor in a display interface of the display screen to move along a similar path. Meanwhile, when the user presses the touch panel 12, the touch panel 12 can move relative to the housing 11, or the touch panel 12 can descend relative to the housing 11 as shown in fig. 3; when the pressing force of the user pressing the touch panel 12 is removed, the elastic restoring force of the elastic support 13 may drive the touch panel 12 to be reset, or the touch panel 12 may be moved upward with respect to the housing as shown in fig. 3. The pressure sensor is used for detecting the movement of the touch pad 12 relative to the housing 11, and further, when the detection device 14 detects that the movement state of the touch pad 12 relative to the housing 11 meets the preset condition, the notebook computer can perform the same function as when the user clicks a specific button of the mouse.
The above-mentioned preset condition may be generated by the user pressing the keypad 400 a plurality of times in a preset time, and thus it may be understood that the touch panel 12 is cyclically moved a plurality of times in a preset time with respect to the housing 11. For example, the user presses the touch pad 12 in one second, the notebook computer can perform a function of clicking a left button of the mouse, and the user presses the touch pad 12 in two seconds, the notebook computer can perform a function of double clicking a right button of the mouse. Alternatively, the preset condition may be that the touch panel 12 moves to a specific position of the housing 11; for example, when the user lightly presses the touch panel 12 to move the touch panel 12 by 0.1 mm with respect to the housing 11, the notebook computer may perform a function of clicking a certain button of the mouse, and when the user highly presses the touch panel 12 to move the touch panel 12 by 0.3mm with respect to the housing 11, the notebook computer may perform a function of double clicking a certain button of the mouse; it will be appreciated that embodiments of the application are not limited in this regard.
With continued reference to fig. 4, fig. 4 is a partially enlarged view of a portion Y of the cross-sectional view of the touch device shown in fig. 3 along the A-A direction. The touch panel 12 may include a touch panel 121 and a control circuit board 122. The touch panel 121 is disposed on a side of the control circuit board 122 facing away from the elastic support 13. The touch panel 121 may be a capacitive touch panel, and after the touch panel 121 is electrically connected with the control circuit board 122, the touch panel 121 can convert a touch signal of a user into a capacitive signal and transmit the capacitive signal to the control circuit board 122, so that the control circuit board 122 can receive the touch signal of the user and transmit the touch signal to a processor of the notebook computer, and the processor of the notebook computer can execute corresponding functions according to the touch operation of the user.
The connection manner of the touch panel 121 and the control circuit board 122 may be various, for example, the touch panel 121 and the control circuit board 122 are connected by a fastener, or the touch panel 121 and the control circuit board 122 are fixed by glue bonding, which is not limited in the embodiment of the present application.
It will be appreciated that the magnitude of the deformation of the resilient support 13 will vary during actual use, depending on the pressure with which the user presses the keyboard 400. When the magnitude of deformation of the elastic support 13 is excessively large, irreversible plastic deformation of the elastic support 13 may occur. On the one hand, after the elastic support 13 is irreversibly deformed, the touch pad 12 will warp, so as to affect the use of the entire touch pad 12 and the aesthetic appearance of the entire base 200 of the notebook computer. On the other hand, the elastic support 13 may also affect the normal operation of the pressure sensor after undergoing irreversible plastic deformation; for example, when the pressure sensor includes a sensor for detecting the relative positions of the housing 11 and the touch panel 12, after the elastic support 13 is plastically deformed, an error is generated between the relative positions of the housing 11 and the touch panel 12 and the preset relative positions of the housing 11 and the touch panel 12, so that the detection accuracy of the pressure sensor may be reduced or even disabled; of course, the result and reason of the influence on the pressure sensor after the elastic support 13 is plastically deformed are different according to the working principle of the pressure sensor.
Based on this, in some embodiments, the touch device 100 further includes a limiting mechanism 15. The limiting mechanism 15 is matched with the touch panel 12, and the limiting mechanism 15 is used for limiting the elastic support 13 to generate plastic deformation. Taking the example that the elastic support 13 can deform to enable the touch panel 12 to move in the first direction relative to the housing 11, the limiting mechanism 15 may be used for limiting the elastic support 13 to be plastically deformed when the touch panel 12 moves in the forward direction relative to the housing 11 in the first direction, the limiting mechanism 15 may be used for limiting the elastic support 13 to be plastically deformed when the touch panel 12 moves in the reverse direction relative to the housing 11 in the first direction, and the limiting mechanism 15 may be used for limiting the elastic support 13 to be plastically deformed when the touch panel 12 moves in both the forward direction and the reverse direction relative to the housing 11 in the first direction. Furthermore, in the use process, the touch device 100 can be more stable and reliable, and the notebook computer provided with the touch device 100 is also more stable and reliable.
The first direction may be a straight line direction, and the first direction may also be an arc line direction, which is not limited in the embodiment of the present application. In the following, the technical solution of the embodiment of the present application will be further explained and explained by taking the case that the first direction is approximately perpendicular to the touch panel 12 (the vertical direction shown in fig. 4) as an example.
The limiting mechanism 15 may be fixedly connected with the touch panel 12. The stopper mechanism 15 has a first stopper 1511, and the first stopper 1511 is located on one side of the touch panel 12 in the first direction. The housing 11 has a mounting portion 112, the mounting portion 112 is located between the touch panel 12 and the first stopper portion 1511, and the mounting portion 112 has a gap with the touch panel 12 in the first direction. Based on this, when the touch panel 12 moves downward to a certain distance with respect to the housing 11, the touch panel 12 can abut against the mounting portion 112 to limit the stroke of the downward movement of the touch panel 12 with respect to the housing 11, thereby limiting the downward movement of the touch panel 12 with respect to the housing 11 to the plastic deformation of the elastic support 13. When the touch panel 12 moves upward to a certain distance with respect to the housing 11, the first stopper portion 1511 can abut against the mounting portion 112 to limit the stroke of the upward movement of the touch panel 12 with respect to the housing 11, thereby limiting the plastic deformation of the elastic support 13 when the touch panel 12 moves upward with respect to the housing 11. Of course, when the elastic support 13 is disconnected from the housing 11 or the elastic support 13 is disconnected from the touch panel 12, the engagement of the mounting portion 112 with the stopper mechanism 15 can restrict the touch panel 12 from falling off the housing 11.
In some embodiments, the mounting portion 112 and the first limiting portion 1511 may also have a gap in the first direction. For example, the distance between the first limiting portion 1511 and the mounting portion 112 is D2, and the upward travel of the touch pad 12 relative to the housing 11 can be controlled by adjusting D2, so as to avoid the elastic connection arm 132 from generating unrecoverable plastic deformation under the excessive tensile force of the touch pad 12.
In some embodiments, the spacing mechanism 15 also has a second spacing portion 1521 and a connecting portion 1522. The second stopper 1521 is connected to the touch panel 12. The connection portion 1522 is disposed on a side of the second limiting portion 1521 facing away from the touch panel 12 along the first direction (or the vertical direction), and is connected to the first limiting portion 1511, where the first limiting portion 1511 is disposed on a side of the connection portion 1522 facing away from the touch panel 12 along the first direction. At this time, the mounting portion 112 of the housing 11 is located between the first and second stopper portions 1511 and 1521, and the mounting portion 112 and the second stopper portion 1521 have a gap D1 in the first direction. Further, when the user presses the touch panel 12, the touch panel 12 together with the stopper mechanism 15 may move downward with respect to the housing 11 until the second stopper 1521 abuts against the mounting portion 112 to achieve the stopper. It can be appreciated that, compared to the limit achieved by the touch pad 12 directly contacting the mounting portion 112, the limit achieved by the second limit portion 1521 replacing the collision between the touch pad 12 and the housing 11 can reduce the probability of damage caused by the collision of the touch pad 12, thereby improving the stability of the touch device 100 and the whole notebook computer. The connection manner of the second stopper 1521 and the touch panel 12 may be varied, such as the connection of the second stopper 1521 and the touch panel 12 by bonding, welding or soldering, which is not limited in the embodiment of the present application.
In some embodiments, mounting holes 111 are provided on mounting portion 112 of housing 11. The connection portion 1522 is movably provided in the mounting hole 111 in the first direction.
Next, taking the mounting hole 111 as a step hole as an example, the limiting mechanism in the embodiment of the present application is further explained and described.
The inner wall of the mounting portion 112 forming the mounting hole 111 includes a first annular wall 1121 near the touch panel 12 and a second annular wall 1122 distant from the touch panel 12.
The inner diameter of the first annular wall 1121 is smaller than the outer diameter of the second limiting portion 1521, so that the second limiting portion 1521 cannot pass through the mounting portion 112, and further the downward travel of the touch pad 12 relative to the housing 11 can be limited by the mounting portion 112 and the second limiting portion 1521.
The inner diameter of the first annular wall 1121 is smaller than the outer diameter of the first limiting portion 1511, so that the first limiting portion 1511 cannot pass through the mounting portion 112, and further the upward travel of the touch panel 12 relative to the housing 11 can be limited by the mounting portion 112 and the first limiting portion 1511. At this time, the distance D2 between the first stopper portion 1511 and the mounting portion 112 is the distance from the stepped surface between the first annular wall 1121 and the second annular wall 1122 to the first stopper portion 1511.
The inner diameter of the first annular wall 1121 is larger than the outer diameter of the connection portion 1522 so that the connection portion 1522 can move up and down in the mounting hole 111. Illustratively, the connection 1522 is spaced from the first annular wall 1121 by a distance D4, where D4 may be greater than 0.2 millimeters, or greater than 0.5 millimeters.
The inner diameter of the second annular wall 1122 is larger than the outer diameter of the first stopper 1511 so that the connecting portion 1522 can move up and down in the mounting hole 111. For example, the first spacing portion 1511 and the second annular wall 1122 may have a distance D3, where D3 may be greater than 0.2 mm, or greater than 0.5 mm.
In some embodiments, the first stop 1511, the connecting portion 1522, and the second stop 1521 may be composed of multiple pieces. Such as the first stopper 1511 is detachably connected with the connecting portion 1522. Further, in the process of assembling, the second stopper portion 1521 and the connecting portion 1522 may be fixed to the touch panel, and then the connecting portion 1522 may be connected to the first stopper portion 1511 through the mounting hole 111. Conversely, the first limiting portion 1511 and the connecting portion 1522 are removed to mount and dismount the touch panel 12, the housing 11, and the limiting mechanism 15. It can be seen that the limiting mechanism 15 of the embodiment of the present application has the advantage of easy disassembly.
The manner in which the first stopper 1511 is detachably connected with the connecting portion 1522 may be various, such as the first stopper 1511 may be detachably connected to the connecting portion 1522 by screwing, sleeving, or clamping, or the like. In the following, taking the first limiting portion screwed to the connecting portion 1522 as an example, the technical solution of the embodiment of the present application is further explained and illustrated.
The connection portion 1522 is provided with a threaded hole 1523 arranged along the first direction, and the threaded hole 1523 may be a blind hole or a through hole. The first limiting portion 1511 further has a threaded post 1512. The threaded post 1512 can be threaded into the threaded bore 1523 such that the first stop 1511 is removably coupled to the connection 1522.
In some embodiments, the spacing mechanism 15 may include a first spacing member 151 and a second spacing member 152. The second stopper 152 has the second stopper portion 1521 and the connecting portion 1522 described above. The first stopper 151 may have an upper first stopper 1511 and a threaded post 1512.
For example, the first stopper 151 may include a first screw, and the second stopper 152 may include a first nut. The first screw may be a large-head screw, and the shaft of the large-head screw forms the threaded post 1512, and the head of the large-head screw forms the first limit portion 1511. A first shoulder of a circle is arranged at one end of the first nut close to the touch pad 12; further, the body of the first nut forms the connecting portion 1522 and the threaded bore 1523, and the first shoulder forms the second stop portion 1521.
The first limiting member 151 may be made of metal, such as copper, copper-nickel plating, etc., which is not limited in the embodiment of the present application. The second limiting member 152 may be made of metal, such as copper, copper-nickel plating, etc., which is not limited in the embodiment of the present application.
Alternatively, the first limiting portion 1511 and the connecting portion 1522 may be integrally formed. For example, the second limiting portion 1521 is fixedly connected to the housing 11, and an elastic back-off (not shown in the drawing) is disposed on a side of the second limiting portion 1521 facing away from the touch pad 12, where a free end of the elastic back-off forms the first limiting portion 1511. At the time of assembly, the elastic back-off may be elastically deformed to pass through the mounting hole 111, and the elastic back-off may be elastically restored after passing through the mounting hole 111, so as to form the above-mentioned structure in which the mounting portion 112 is located between the first and second limiting portions 1511 and 1521.
It should be further understood that the number of the limiting mechanisms 15 may be one or more, which is not limited in the embodiment of the present application. Taking the example that the number of the limit mechanisms 15 is a plurality of, the limit mechanisms 15 may be arranged at intervals along the circumferential direction of the touch panel 12; furthermore, in the process of limiting the position of the limiting mechanism 15, the stress on the housing 11 and the touch pad 12 can be more uniform and reasonable, the touch pad 12 is not easy to damage, and meanwhile, the touch pad 12 can be more flat relative to the whole touch device 100 and the base 200 of the notebook computer without local warping. Illustratively, the touch panel 12 is a rectangular or square plate-like structure, and one of the limit mechanisms 15 is disposed at each of the four corners of the touch panel 12.
With continued reference to fig. 5, fig. 5 is an exploded view of the touch device shown in fig. 2. The elastic bracket 13 may include a bracket body 131 and an elastic connection arm 132 connected to each other. The elastic connection arm 132 is provided at an end of the bracket body 131 along a second direction different from the first direction. The bracket main body 131 is fixedly connected to the housing 11. The touch panel 12 is fixedly connected to the elastic connection arm 132. When the user presses the touch panel 12, the elastic support 13 is elastically deformed to move the touch panel 12 in the first direction with respect to the housing 11.
The second direction may be perpendicular to the first direction, such as the first direction being a vertical direction and the second direction being a horizontal direction. The second direction may also be oblique to the first direction, such as the first direction being a vertical direction, the second direction being an obliquely downward direction or an obliquely upward direction, as embodiments of the present application are not limited in this respect.
With continued reference to fig. 6, fig. 6 is a schematic structural diagram of an elastic support, a strain type pressure sensor and a flexible circuit board of the touch device shown in fig. 2. The pressure sensor may comprise a strain gauge pressure sensor 141. The strain gauge pressure sensor 141 is a type of pressure sensor that converts measured pressure into a corresponding resistance value change using an elastic sensing element and a strain gauge. The strain gauge pressure sensor 141 may be provided on the resilient connecting arm 132.
It will be appreciated that when the user presses the touch pad 12, the touch pad 12 moves relative to the housing 11, and the elastic connection arm 132 is elastically deformed adaptively, and the strain type pressure sensor 141 detects the stress change of the elastic connection arm 132 during the deformation, so that the user pressing the touch pad 12 is detected.
In some embodiments, the touch device 100 may further include a flexible circuit board 142. The flexible circuit board 142 is disposed on the elastic support 13 and is capable of being adaptively deformed according to the deformation of the elastic support 13. The flexible circuit board 142 and the strain pressure sensor 141 are electrically connected. Further, the pressing information of the user pressing the touch panel 12 detected by the strain type pressure sensor 141 can be received through the flexible circuit board 142. At this time, it may be connected to the control circuit board 122 of the touch panel 12 through the flexible circuit board 142 so that the pressing information can be transferred to the control circuit board 122; alternatively, the flexible circuit board 142 is connected to the processor of the notebook computer so that the processor of the notebook computer can receive the pressing information and perform the corresponding operation.
The flexible circuit board 142 may be disposed on the bracket body 131 of the elastic bracket 13, may be disposed on the elastic connection arm 132 of the elastic bracket 13, or may be partially disposed on the bracket body 131 or partially disposed on the elastic connection arm 132, which is not limited in the embodiment of the present application.
The flexible circuit board 142 may be disposed on the surface of the elastic support 13 facing the touch panel 12, or may be disposed on the surface of the elastic support 13 facing away from the touch panel 12, which is not limited in the embodiment of the present application.
In some embodiments, the flexible circuit board 142 is located on a side of the elastic support 13 facing away from the touch device 100, and the flexible circuit board 142 is partially disposed on the support body 131 and partially disposed on the elastic connection arm 132. The strain gauge pressure sensor 141 is a diaphragm type structure, so as to be laid on a portion of the flexible circuit board 142 located on the elastic connection arm 132.
The number of the elastic connection arms 132 may be one or more. Illustratively, the bracket body 131 is a rectangular plate disposed generally parallel to the touch panel 12. The bracket main body 131 may have one, two or three elastic connection arms 132 extending from each short side, and the elastic connection arms 132 on the two short sides of the bracket main body 131 are symmetrically arranged one by one. Or the bracket main body 131 may have one, two or three elastic connection arms 132 extending from each long side, and the elastic connection arms 132 on the two long sides of the bracket main body 131 are symmetrically arranged one by one. Of course, the bracket main body 131 may be provided with the elastic connection arm 132 only on the long side, may be provided with the elastic connection arm 132 only on the short side, and may be provided with the elastic connection arm 132 on both the short side and the long side, which is not limited by the embodiment of the present application.
In order to cause elastic deformation of the elastic support 13 to mainly concentrate on the elastic connection arm 132 so as to improve detection accuracy of the strain type pressure sensor 141, the rigidity of the elastic connection arm 132 may be lower than that of the support main body 131.
For example, the thickness of the elastic connection arm 132 may be smaller than the thickness of the bracket body 131, or the elastic connection arm 132 may be thinner than the bracket body 131, and the thickness of the elastic connection arm 132 may be understood as a distance between both surfaces of the elastic connection arm 132 in the first direction. Alternatively, the width of the elastic connection arm 132 may be smaller than the width of the bracket body 131, or the elastic connection arm 132 may be narrower than the bracket body 131, and the width of the elastic connection arm 132 may be understood as a distance between two surfaces of the elastic connection arm 132 along a third direction, which is perpendicular to the first direction and the second direction, respectively.
In some embodiments, in order to make the elastic deformation of the elastic support 13 mainly occur on the elastic connection arm 132, stress slits (not shown in the figure) may be opened on the elastic connection arm 132.
Alternatively, please continue to refer to fig. 7, fig. 7 is a partially enlarged view of the cross-section of the touch device along the A-A direction shown in fig. 3 at X. In order to make the elastic deformation of the elastic support 13 mainly concentrated on the elastic connection arm 132, the connection between the support body 131 and the elastic connection arm 132 is provided with a reinforcement 16, and the reinforcement 16 is detachably connected with the housing 11, so that the stress gap is replaced by the reinforcement 16. Therefore, during the movement of the touch panel 12 relative to the housing 11, a portion of the elastic support 13 extending from the reinforcing member 16 in a direction away from the free end of the elastic connection arm 132 is hard to be elastically deformed. Alternatively, the portion of the flexible bracket 13 extending from the reinforcement member 16 to the free end of the flexible connecting arm 132 is subject to elastic deformation. Further alternatively, the reinforcement 16 serves as a fulcrum at which the elastic deformation of the elastic bracket 13 occurs, and the free end of the elastic connection arm 132 of the elastic bracket 13 is terminated at an inelastic deformed portion so that the elastic deformation of the elastic bracket 13 is concentrated between the fulcrum and the free end of the elastic connection arm 132. In addition, compared with the structure provided with the stress gap, the manner of providing the reinforcement member 16 can make the strength of the elastic support 13 higher and not easy to break, so that the touch device 100 is not easy to damage when the touch pad 12 receives a larger pressing force or pulling force, thereby improving the stability of the touch device 100.
The detachable connection of the reinforcement 16 to the housing 11 may be varied, such as a snap-fit, socket-fit, screw-fit, etc. For example, the reinforcement 16 may include a second screw 162 and a second nut 161. The second nut 161 is fixed to the elastic bracket 13. The second screw 162 penetrates the housing 11 and is then screwed and fixed to the second nut 161. Each reinforcement 16 may be formed by one, two or three sets of second nuts 161 and second screws 162 that are matched with each other, which is not limited in the embodiment of the present application.
The connection between the bracket main body 131 and the elastic connection arm 132 is provided with the reinforcement 16, which may be that the reinforcement 16 is fixed on the bracket main body 131, or that the reinforcement 16 is fixed on the elastic connection arm 132, or that the reinforcement 16 is partially fixed on the bracket main body 131 and partially fixed on the elastic connection arm 132, which is not limited in the embodiment of the present application.
Illustratively, the connecting end of the elastic connecting arm 132 is fixedly connected to the bracket main body 131. The reinforcement 16 is disposed on the connection end of the resilient connection arm 132. At this time, the strain gauge pressure sensor 141 is at least partially disposed on the stiffener 16 and the free ends of the elastic connection arm 132, so that the strain gauge pressure sensor 141 can better detect the stress variation when the elastic connection arm 132 is elastically deformed.
Alternatively, the reinforcement 16 may be provided at the end edge of the bracket main body 131 so that the elastic deformation of the elastic bracket 13 mainly occurs concentrated on the elastic connection arm 132.
In combination with the bracket body 131, one or more elastic connection arms 132 may be provided, and one or more reinforcing members 16 may be provided on the bracket body 131. Each resilient connecting arm 132 corresponds to at least one stiffener 16.
Taking each elastic connection arm 132 as an example corresponding to one reinforcement member 16, the free end of each elastic connection arm 132 is equally spaced from the corresponding reinforcement member 16. Further, during the elastic deformation of the elastic support 13, the magnitude and state of the elastic deformation of each elastic connection arm 132 are more uniform. In combination with the notebook computer, the base 200 is placed on a computer desk, and the shape of each elastic connecting arm 132 is more consistent when the elastic connecting arms are elastically deformed, so that the touch pad 12 can be wholly sunk downwards, local warping is not easy to occur, and the overall attractiveness of the notebook computer is higher.
Taking each elastic connection arm 132 as an example corresponding to a plurality of stiffeners 16, the free end of any elastic connection arm 132 is equidistant from its corresponding stiffener 16. Further, during the elastic deformation of the elastic support 13, the magnitude and state of the elastic deformation of each elastic connection arm 132 are more uniform. Such as shown in fig. 6, each stiffener 16 is spaced from the free end of the corresponding resilient connecting arm 132 by a distance D5.
Alternatively, as shown in fig. 8, fig. 8 is a schematic diagram illustrating another arrangement of the elastic support and the reinforcement members of the touch device shown in fig. 5, taking each elastic connection arm 132 and a plurality of reinforcement members 16 as an example, a corresponding group of elastic connection arms 132 and all reinforcement members 16 are arranged similarly, and distances from each reinforcement member 16 corresponding to the same elastic connection arm 132 to the elastic connection arm 132 are not equal.
Such as each spring link arm 132 being grouped with two corresponding stiffeners 16. Within the same group, one stiffener 16 corresponding to the elastic connection arm 132 is provided at a position distant from the elastic connection arm 132 by D6, and another stiffener 16 corresponding to the elastic connection arm 132 is provided at a position distant from the elastic connection arm 132 by D7. Further, during the elastic deformation of the elastic support 13, the magnitude and state of the elastic deformation of each elastic connection arm 132 are more uniform.
With continued reference to fig. 9, fig. 9 is an assembly schematic diagram of the elastic support and other parts of the touch device shown in fig. 2. The touch device 100 may further include an actuator 17 such as a rotor motor, a linear motor, etc. An actuator 17 is coupled to the touch panel 12 for driving the touch panel 12 to vibrate. Further, when the user operates the touch panel 12, the actuator 17 may drive the touch panel 12 to vibrate to provide feedback to the user, thereby improving the user experience. For example, the actuating member 17 may be fixed to a side of the control circuit board 122 facing away from the touch panel 121, and the actuating member 17 is electrically connected to the control circuit board 122.
In order to make the vibration of the touch panel 12 softer to improve the user experience when the actuation member 17 drives the touch panel 12 to vibrate, the touch panel 12 may be provided with the elastic member 18, so that the elastic member 18 may have a certain vibration absorbing effect on the touch panel 12.
Illustratively, the resilient member 18 is located between the touch pad 12 and the resilient connecting arm 132. The elastic members 18 are fixedly connected with the elastic connection arms 132 and the touch panel 12, respectively. Based on this, the elastic member 18 not only can play a role in absorbing vibration to the touch panel 12, but also can play a role in connecting the touch panel 12 and the elastic connection arm 132, so that the pressing force received by the touch panel 12 can be transferred to the elastic support 13, and the elastic restoring force of the elastic support 13 itself can be transferred to the touch panel 12.
In combination with the bracket main body 131, one or more elastic connection arms 132 may be provided, and the elastic member 18 may also have one or more elastic members. Specifically, each of the elastic connection arms 132 may be connected and fixed to the touch pad 12 through one or more elastic members 18.
With continued reference to fig. 10, fig. 10 is a schematic structural diagram of an elastic member of the touch device shown in fig. 3. The elastic member 18 may be made of a flexible material. For example, the elastic member 18 may be silica gel, rubber, TPU (Thermoplastic polyurethanes, thermoplastic polyurethane elastomer), TPE (Thermoplastic Elastomer ), foam, and the like, and both opposite surfaces of the elastic member 18 are provided with adhesive layers 181 to be connected to the touch pad 12 and the elastic connection arms 132, respectively. The adhesive layer 181 may be double-sided adhesive tape, glue, or the like.
In some embodiments, limiting the travel of the movement of the touch pad 12 relative to the housing 11 by the limiting mechanism 15 described above may also reduce the probability of disconnection of the elastic member 18 from the touch pad 12, and may reduce the probability of disconnection of the elastic member 18 from the elastic connection arm 132. Therefore, on one hand, the limiting mechanism 15 improves the overall stability of the touch device 100; on the other hand, the limiting mechanism 15 can also reduce the requirement and cost for the material of the elastic member 18, and can also reduce the requirement for the gluing process of the gluing layer 181, thereby reducing the overall process difficulty and cost of the touch device 100. Or the probability of disconnection of the elastic member 18 from the elastic connection arm 132.
In some other embodiments, the touch device 100 may further include a communication unit (not shown), so that the touch device 100 and even the whole notebook computer can communicate with other intelligent terminals of the user, such as a mobile phone, through the communication unit. For example, the Communication unit may include an NFC (NEAR FIELD Communication) antenna or a bluetooth antenna, which is not limited by the embodiment of the present application. Taking the example that the communication unit includes an NFC antenna, the NFC antenna may be a coil disposed on the control circuit board 122.
