Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The embodiment of the application provides a touch device 100, which can be applied to an electronic device as an input device of the electronic device, so that a user can input a control signal to the electronic device through the touch device 100, so as to implement a human-computer interaction operation between the user and the electronic device. The electronic device may be a notebook computer, a television, a palm tablet computer, and the like, which is not limited in this 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 an input device for the user to operate the notebook computer. It can be understood that, during the process of using the notebook computer, a user usually needs to use a mouse connected to the notebook computer for operation, in order to improve the convenience of the notebook computer, a touch device 100 is usually disposed on the base 200, and the user can implement the same function as the mouse operation by operating on the touch device 100.

Referring to fig. 2 and fig. 3, fig. 2 is a bottom view of the touch device and the housing of the electronic device shown in fig. 1, and fig. 3 is an exploded view of the touch device and the housing shown in fig. 2. The touch device 100 may include a touch panel 12, an NFC (Near Field Communication) coil 13, and a control module. The touch panel 12 is used for receiving a touch signal of a user, such as receiving a stroke path of a finger of the user on the touch panel 12 through the touch panel 12, and the processor of the notebook computer can accordingly drive a cursor in the display interface of the display screen 300 to move along a similar path. The NFC coil 13 is disposed on the touch panel and configured to couple with a first metal unit 111 spaced apart by a preset distance to perform resonance, and the first metal unit 111 is located on a side of the NFC coil 13 away from the touch panel 12; furthermore, when the distance between the NFC coil 13 and the first metal unit 111 changes, the inductance strength of the NFC coil 13 also changes. The control module is electrically connected with the NFC coil 13 and is used for detecting the inductance strength of the NFC coil 13.

The following takes an example in which the electronic device is a notebook computer, and the operating principle of the touch device 100 is further explained and explained by combining the touch device 100 with one of the matching structures of the notebook computer.

The touch pad 12 may be directly or indirectly movably mounted on the base 200 of the notebook computer, and the first metal unit 111 may be fixedly disposed on the base 200 of the notebook computer. Therefore, when the user presses the touch panel 12, the touch panel 12 moves together with the NFC coil 13 in a direction approaching the first metal unit 111, so that the strength of the inductance of the NFC coil 13 becomes large; when the pressure of the user pressing the touch panel 12 is released, the touch panel 12 together with the NFC coil 13 is reset to move in a direction away from the first metal unit 111, so that the strength of the inductance of the NFC coil 13 becomes small. At this time, the control module directly detects the inductance strength of the NFC coil 13, so that the function of detecting the action of pressing the touch panel 12 by the user can be realized.

Therefore, in the embodiment of the present application, the NFC coil 13 can be used for both communication and detecting two functions of pressing the touch panel 12 by the user, so as to reduce functional parts required when the touch device has an NFC antenna and detects two functions of pressing the touch panel 12 by the user, and further make the overall structure of the touch device 100 simpler, and more suitable for large-scale industrial production.

Taking the electronic device as a notebook computer as an example, in order to improve the portability of the notebook computer, the overall volume of the notebook computer is smaller, and the area of the corresponding touch device 100 is also smaller. At this time, as shown in fig. 4, in order to ensure the strength of the near field communication signal radiated to the surface of the touch device 100 by the NFC coil 13, the area of the NFC coil 13 may be increased. Therefore, the orthographic projection area of the NFC coil 13 on the touch panel 12 may occupy more than one sixth of the area of the touch panel 12. For example, the orthographic area of the NFC coil 13 on the touch panel 12 occupies one fifth of the area of the touch panel 12.

Of course, when the electronic device is a product with a larger volume, the area of the touch device 100 is also larger, and the forward projection area of the NFC coil 13 on the touch panel 12 may also occupy less than one sixth of the area of the touch panel 12, which is not limited in the embodiment of the present application.

Through the investigation and research to the use habit of the user, when the NFC coil 13 is only one, the NFC coil 13 can be arranged in the middle of the touch panel 12, so that the user can quickly connect the smart terminal such as a mobile phone with the NFC coil 13. Of course, when the area of the touch panel 12 is large, the NFC coil 13 may be provided in multiple numbers, and the multiple NFC coils 13 are dispersedly provided on the touch panel 12, which is not limited in this embodiment of the application.

The NFC coil 13 may be a spiral structure, and the shape of the spiral formation thereof may be various. For example, as shown in fig. 4, fig. 4 is a schematic shape diagram of a first NFC coil of the touch device shown in fig. 3, and the NFC coil 13 may be a perfect circle. Alternatively, as shown in fig. 5, fig. 5 is a schematic shape diagram of a second NFC coil of the touch device shown in fig. 3, and the NFC coil 13 may be square. As shown in fig. 6, fig. 6 is a schematic shape diagram of a third NFC coil of the touch device shown in fig. 3, and the NFC coil 13 may be rectangular.

The control module may include a detection unit and a control unit. The detection unit is electrically connected to the NFC coil 13 and is configured to detect the inductance strength of the NFC coil 13. The control unit is electrically connected to the detection unit to detect an operation of the user pressing the touch panel 12 based on a detection result of the detection unit.

It is understood that the strength of the inductance of the NFC coil 13 is related to the distance between the NFC coil 13 and the first metal unit 111, and when the user presses the touch pad 12 with different pressure, the NFC coil 13 on the touch pad 12 can move to different distances of the first metal unit 111; therefore, the control unit may detect the inductance strength of the NFC coil 13 through the detection unit to calculate the distance between the NFC coil 13 and the first metal unit 111 according to the inductance strength of the NFC coil 13, and finally the control unit may also calculate the pressure applied by the user to press the touch pad 12 according to the distance between the NFC coil 13 and the first metal unit 111.

Next, the NFC coil 13 and the control module according to the embodiment of the present application will be further explained and explained with reference to one of the structures of the touch panel 12.

The touch panel 12 may include a touch panel 121 and a circuit board 122. The circuit board 122 is disposed on a side of the touch panel 121 facing the NFC coil 13. The touch panel 121 may be a capacitive touch panel 121, and after the touch panel 121 is electrically connected to the circuit board 122, the touch panel 121 may convert a touch signal of a user into a capacitive signal and transmit the capacitive signal to the circuit board 122, so that the circuit board 122 may receive the touch signal of the user and transmit the capacitive signal to a processor of the notebook computer, and the processor of the notebook computer may execute a corresponding command 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 fixed by bonding with an adhesive layer 123 formed by glue, double-sided tape, or the like, which is not limited in this embodiment of the application.

The control module may be disposed on the circuit board 122. For example, the detection unit may be a component or a circuit, such as an inductance strength detection circuit disposed on the circuit board 122, which can be used to detect the inductance strength, and this is not limited in this embodiment of the application. The control unit may be a control chip disposed on the circuit board 122, and the like, which is not limited in this embodiment of the application. Of course, in some other embodiments, the control module may also be disposed on other components of the notebook computer, which is not limited in this application.

Referring to fig. 7, fig. 7 is a schematic diagram of an NFC coil of the touch device shown in fig. 3, and the NFC coil 13 may be disposed on the circuit board 122 to be electrically connected to the control module. For example, the NFC coil 13 is provided on a side of the circuit board 122 away from the touch panel 121.

The electronic device may further include a housing 11, and the touch device 100 is disposed on the housing 11. Taking the electronic device as a notebook computer, the housing 11 may be a part of the casing of the base 200; the housing 11 may also be formed of one or more parts that are separate from the base 200 and the housing 11 and the base 200 are fixedly attached. Therefore, the touch device 100 can be mounted on the notebook computer through the housing 11.

The first metal unit 111 described above may be provided on the case 11. The first metal unit 111 is located on a side of the NFC coil 13 away from the touch panel 12, and is spaced from the NFC coil 13 by a preset distance, and the first metal unit 111 is configured to couple with the NFC coil 13 to perform resonance. It can be understood that, because the first metal unit 111 is located on the side of the NFC coil 13 away from the touch panel 12, interference caused by resonance between the NFC coil 13 and the first metal unit 111 when the touch panel 12 is located between the first metal unit 111 and the NFC coil 13 can be effectively avoided. Therefore, the touch device 100 of the embodiment of the present application further has an advantage of high reliability.

In some embodiments, the first metal unit 111 may include a first metal film attached to the case 11. The first metal film may be made of a material having good conductivity, such as copper foil or aluminum foil. The first metal film is used as the first metal unit 111 to reduce the overall cost of the touch device 100, and to make the touch device 100 thinner.

Optionally, the housing 11 may further include a metal part, the metal part is located on a side of the NFC coil 13 away from the touch panel 12 and is spaced from the NFC coil 13 by a preset distance, and the metal part is configured to couple with the NFC coil 13 to perform resonance. Specifically, the housing 11 itself is made of a metal material to form the metal portion.

Referring to fig. 8, fig. 8 is an exploded view of the touch device shown in fig. 3 with a second coil and an actuator. In order to enhance the near field communication signal radiated by the NFC coil 13 to the surface of the touch device 100, the housing 11 may further include a ferrite 112, and the ferrite 112 is disposed on a side of the first metal unit 111 facing away from the NFC coil 13.

It is understood that the NFC coil 13 radiates the near field communication signal to radiate around the NFC coil 13, and when a portion of the near field communication signal radiated by the NFC coil 13 is directed to the ferrite 112, the ferrite 112 reflects the portion of the near field communication signal to the outside of the touch device 100 from the side of the touch pad 12, i.e., the ferrite 112 can enhance the near field communication signal radiated by the NFC coil 13 to the surface of the touch device 100.

The ferrite 112 may be a film or a sheet of ferrite material attached to the housing 11, or the ferrite 112 may also be a coating of ferrite material coated on the housing 11, which is not limited in this embodiment. In practical applications, a layer of ferrite material may be first disposed on the housing 11 to form the ferrite 112, and then a first metal film is attached to a side of the ferrite 112 facing the NFC coil 13 to form the first metal unit 111.

The touch device 100 may further include a second coil 14. The second coil 14 is provided on a side of the circuit board 122 facing the housing 11. The second coil 14 and the NFC coil 13 are offset from each other in the orthographic projection on the touch panel 12. The case 11 is provided with a second metal unit 113 facing the second coil 14. The second metal unit 113 is coupled with the second coil 14 to resonate. Therefore, when the relative position of the second metal unit 113 and the second coil 14 is changed, the inductance strength of the second coil 14 is changed, that is, the inductance strength of the second coil 14 is changed when the user presses the touch pad 12 to move the touch pad relative to the housing 11. At this time, the second coils 14 are also electrically connected to the control module, so that the control module can detect the strength of inductance of the second coils 14 to detect the user's operation of pressing the touch panel 12. It can be understood that a simple second coil 14 is adopted in the embodiment of the present application to detect the operation of pressing the touch pad by the user, so that the structure of the touch device 100 is simpler and the manufacturing cost is lower, and thus the touch device is more suitable for mass industrial production.

In some embodiments, the second coil 14 does not need to be an NFC antenna, so the second coil 14 does not need to be made large to ensure the signal strength of the NFC antenna, and thus the orthographic projection area of the second coil 14 on the touch panel 12 may be smaller than that of the NFC coil 13 on the touch panel.

The second coil 14 may be provided with only one or a plurality of coils, which is not limited in the embodiment of the present application.

In some embodiments, taking the example that the second coil 14 is provided in plural, the plural second coils 14 may be arranged on the touch panel 12 symmetrically with respect to the center line of the touch panel 12. For example, one second coil 14 is disposed at each of the four corners of the touchpad 12.

When the number of the second coils 14 is plural, a plurality of second metal units 113 may be disposed on the housing 11, the plurality of second metal units 113 correspond to the second coils 14 one by one, and the corresponding second metal units 113 are coupled to the second coils 14 to resonate; it is also possible that one second metal unit 113 is provided on the case 11, and each second coil 14 is coupled with the second metal unit 113 to resonate.

In some embodiments, the housing 11 itself is made of a metal material to form the second metal unit 113, and both the NFC coil 13 and the second coil 14 may be coupled to the housing 11 to resonate. Alternatively, the second metal unit 113 may include a second metal film attached to the case 11. The second metal film may be made of a material with good conductivity, such as copper foil or aluminum foil, so as to reduce the overall cost of the touch device 100.

The touch device 100 may further include an actuator 15 such as a rotator motor, a linear motor, etc. The actuator 15 is connected to the touch panel 12 for driving the touch panel 12 to vibrate. Further, the actuator 15 may drive the touch pad 12 to vibrate to provide a feedback to the user when the user operates the touch pad 12, thereby improving the user experience. For example, the actuator 15 may be fixed on a side of the circuit board 122 facing away from the touch panel 121, and the actuator 15 is electrically connected to the circuit board 122.

In order to make the vibration of the touch pad 12 softer and improve the user experience when the actuator 15 drives the touch pad 12 to vibrate, the elastic connection member 16 may be disposed on the touch pad 12, so that the elastic connection member 16 may have a certain vibration absorption effect on the touch pad 12.

Illustratively, the elastic connector 16 is disposed on the same side of the touch pad 12 as the NFC coil 13. The housing 11 is fixedly connected to a side of the elastic connection member 16 facing away from the touch pad 12. The elastic connection member 16 can be elastically deformed to move the housing 11 and the touch pad 12 toward and away from each other.

Of course, the elastic connection member 16 may also be used as a connection means for movably connecting the touch pad 12 with the housing 11. Therefore, the touch panel 12 may be provided with only the actuator 15, only the elastic connector 16, or both the actuator 15 and the elastic connector 16, which is not limited in the embodiment of the present invention.

The elastic connection member 16 may have a ring structure such as a square ring structure, a rectangular ring structure, a cross ring structure, etc., which is not limited in the embodiments of the present application.

The elastic connection 16 may be made of an elastic material. For example, the elastic connector 16 may be silicone rubber, TPU (Thermoplastic polyurethane elastomers), TPE (Thermoplastic elastomers), foam, or the like. The opposite surfaces of the elastic connection member 16 are provided with adhesive layers to connect the touch pad 12 and the housing 11, respectively. The adhesive layer can be double-sided adhesive tape or glue, etc.

With reference to fig. 3, in order to avoid the situation that the elastic connecting member 16 is damaged, the elastic connecting member 16 is disconnected from the housing 11, the elastic connecting member 16 is disconnected from the touch pad 12, and the like when the pressing force or the pulling force applied to the touch pad 12 is too large, the touch device 100 further includes a limiting mechanism 17, and the limiting mechanism 17 is used for limiting the stroke of the movement of the housing 11 and the touch pad 12. Furthermore, the touch device 100 can be more stable and reliable during the use process, and the notebook computer provided with the touch device 100 is also more stable and reliable.

Referring to fig. 9, fig. 9 isbase:Sub>A cross-sectional view of the touch device and the housing shown in fig. 2 alongbase:Sub>A directionbase:Sub>A-base:Sub>A. The electronic device may further include a limiting mechanism 17, and the limiting mechanism 17 is used for limiting the stroke of the relative movement between the touch pad 12 and the housing 11. Furthermore, when the external force applied to the touch pad 12 by the user is too large, part of the external force applied by the user can be shared by the limiting mechanism 17, so as to avoid the connection structure of the touch pad 12 and the housing 11 from being damaged due to too large force.

For example, referring to fig. 10, fig. 10 isbase:Sub>A partial enlarged view ofbase:Sub>A cross-sectional view of the touch device and the housing alongbase:Sub>A directionbase:Sub>A-base:Sub>A shown in fig. 9 atbase:Sub>A position X. The touch pad 12 is movably connected to the housing 11 in a first direction, and the housing 11 has a mounting portion 115, and the mounting portion 115 is spaced apart from the touch pad 12 in the first direction. The first direction may be a linear direction, and the first direction may also be an arc direction, which is not limited in the embodiment of the present application. In the following, taking the first direction as a vertical direction as an example, the technical solution of the embodiment of the present application is further explained and explained. 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 115 to limit the stroke of the downward movement of the touch panel 12 with respect to the housing 11.

The limiting mechanism 17 is connected with the touch pad 12, the limiting mechanism 17 has a first limiting portion 1711, and the first limiting portion 1711 is located on one side of the mounting portion 115 facing away from the touch pad 12 along the first direction. When the touch pad 12 moves upward to a certain distance with respect to the housing 11, the first stopper 1711 can abut against the mounting portion 115 to limit the upward movement stroke of the touch pad 12 with respect to the housing 11. Of course, when the touch panel 12 is disconnected from the housing 11, the touch panel 12 can be restricted from falling off the housing 11 by the engagement of the mounting portion 115 and the stopper mechanism 17. Therefore, the touch device 100 in the embodiment of the present application can be more stable and less prone to damage by providing the limiting mechanism 17.

In some embodiments, the mounting portion 115 and the first position-limiting portion 1711 may have a gap in the first direction. Illustratively, the first position-limiting portion 1711 is spaced from the mounting portion 115 by a distance D2, and the upward stroke of the touch pad 12 relative to the housing 11 can be controlled by adjusting D2. D2 may be greater than 0.1 mm.

In some embodiments, the limiting mechanism 17 further has a second limiting portion 1721 and a connecting portion 1722. The second stopper portion 1721 is connected to the touch panel 12. The connecting portion 1722 is disposed on a side of the second limiting portion 1721 facing away from the touchpad 12 along the first direction (or the vertical direction) and connected to the first limiting portion 1711, and the first limiting portion 1711 is disposed on a side of the connecting portion 1722 facing away from the touchpad 12 along the first direction. At this time, the mounting portion 115 of the housing 11 is located between the first stopper portion 1711 and the second stopper portion 1721, and the mounting portion 115 and the second stopper portion 1721 have a gap D1 in the first direction. Further, when the user presses the touch pad 12, the touch pad 12 together with the position limiting mechanism 17 may move downward relative to the housing 11 until the second position limiting portion 1721 abuts against the mounting portion 115 to achieve the position limiting. It can be understood that, compared with the case that the touch pad 12 is directly contacted with the mounting portion 115 to realize the limiting, the second limiting portion 1721 is used for replacing the touch pad 12 to collide with the housing 11 to realize the limiting, so that the probability of collision damage of the touch pad 12 can be reduced, and the stability of the touch device 100 and the whole notebook computer can be further improved.

The connection manner of the second position limiting portion 1721 and the touch panel 12 may be various, for example, the second position limiting portion 1721 is connected to the touch panel 12 by bonding, welding or soldering, which is not limited in this embodiment of the application.

The structure of the limiting mechanism 17 for limiting the matching with the mounting part 115 of the shell 11 can be various. For example, the mounting portion 115 of the housing 11 is provided with a mounting hole 114. The connecting portion 1722 is movably inserted into the mounting hole 114 in the first direction.

Next, the limiting mechanism 17 in the embodiment of the present application will be further explained and explained by taking the mounting hole 114 as a stepped hole as an example.

The inner walls of the mounting portion 115 that form the mounting aperture 114 include a first annular wall 1151 that is proximate to the touchpad 12 and a second annular wall 1152 that is distal to the touchpad 12.

The inner diameter of the first ring wall 1151 is smaller than the outer diameter of the second limiting portion 1721, so that the second limiting portion 1721 cannot pass through the mounting portion 115, and the downward stroke of the touch pad 12 relative to the housing 11 can be limited by the mounting portion 115 and the second limiting portion 1721.

The inner diameter of the first annular wall 1151 is smaller than the outer diameter of the first position-limiting portion 1711, so that the first position-limiting portion 1711 cannot pass through the mounting portion 115, and the mounting portion 115 and the first position-limiting portion 1711 can limit the upward stroke of the touch pad 12 relative to the housing 11. At this time, a distance D2 between the first stopper portion 1711 and the mounting portion 115 is a distance from the stepped surface between the first annular wall 1151 and the second annular wall 1152 to the first stopper portion 1711.

The inner diameter of the first annular wall 1151 is greater than the outer diameter of the connecting portion 1722 so that the connecting portion 1722 can move up and down in the mounting hole 114. Illustratively, the connection portion 1722 is spaced apart from the first annular wall 1151 by a distance D4, and D4 may be greater than 0.2 mm, or greater than 0.5 mm.

The inner diameter of the second annular wall 1152 is larger than the outer diameter of the first stopper 1711 so that the connecting portion 1722 can move up and down in the mounting hole 114. Illustratively, the first position-limiting portion 1711 is spaced from the second annular wall 1152 by a distance D3, and D3 may be greater than 0.2 mm, or greater than 0.5 mm.

In some embodiments, the first position-limiting portion 1711, the connecting portion 1722, and the second position-limiting portion 1721 may be formed of multiple pieces. For example, the first position-limiting portion 1711 is detachably connected to the connecting portion 1722. Furthermore, in the assembling process, after the second position limiting portion 1721 and the connecting portion 1722 are fixed to the touch panel, the connecting portion 1722 may be inserted into the mounting hole 114 and connected to the first position limiting portion 1711. Conversely, the first stopper portion 1711 and the connecting portion 1722 can be detached to attach and detach the touch pad 12, the housing 11, and the stopper mechanism 17. Therefore, the limiting mechanism 17 of the embodiment of the present application has the advantage of easy disassembly and assembly.

The detachable connection between the first position-limiting portion 1711 and the connecting portion 1722 may be various, such as the first position-limiting portion 1711 may be detachably connected to the connecting portion 1722 by screwing, sleeving or clamping. Next, taking the first position-limiting portion 1711 screwed to the connecting portion 1722 as an example, the technical solution of the embodiment of the present application is further explained and explained.

The connecting portion 1722 is opened with a screw hole 1723 arranged along a first direction, and the screw hole 1723 may be a blind hole or a through hole. The first position-limiting portion 1711 further has a threaded post 1712. The threaded post 1712 can be screwed into the threaded hole 1723 so that the first stopper 1711 can be detachably connected to the connecting portion 1722.

In some embodiments, the limiting mechanism 17 may include a first limiting member 171 and a second limiting member 172. The second position-limiting member 172 has the second position-limiting portion 1721 and the connecting portion 1722. The first limiting member 171 may have an upper first limiting portion 1711 and a threaded post 1712.

For example, the first retaining member 171 may include a large head screw, and the second retaining member 172 may include a first nut. Further, the shank of the big head screw forms the threaded post 1712, and the head of the big head screw forms the first limit portion 1711. One end of the first nut close to the touch pad 12 is provided with a first circular shoulder; further, the body of the first nut forms the connection portion 1722 and the screw hole 1723, and the first shoulder forms the second stopper portion 1721.

The first limiting member 171 may be made of a metal material, such as copper, copper-nickel-plated, etc., which is not limited in this embodiment. The second position-limiting member 172 may be made of a metal material, such as copper, copper-plated nickel, etc., which is not limited in this embodiment of the present invention.

Alternatively, the first position-limiting portion 1711 and the connecting portion 1722 may also be integrally formed. For example, the second position-limiting portion 1721 is fixedly connected to the housing 11, and a side of the second position-limiting portion 1721 opposite to the touch pad 12 is provided with an elastic reverse buckle (not shown), and a free end of the elastic reverse buckle forms the first position-limiting portion 1711. During assembly, the elastic reverse buckle can be elastically deformed to pass through the mounting hole 114, and the elastic reverse buckle can be elastically restored after passing through the mounting hole 114, so as to form the structure that the mounting portion 115 is located between the first position-limiting portion 1711 and the second position-limiting portion 1721.

It should also be understood that the number of the limiting mechanisms 17 may be one or multiple, and this is not limited in the embodiment of the present application.

For example, the position limiting mechanism 17 is only provided at one position, and the position limiting mechanism 17 may be provided at the center of the touch pad 12. Compared with the case that only one limiting mechanism 17 is arranged at one corner of the touch pad 12, in the embodiment of the present application, when the limiting mechanism 17 limits the position, the touch pad 12 is not easily warped locally relative to the base 200 of the notebook computer.

Taking the example that only a plurality of position limiting mechanisms 17 are provided, the plurality of position limiting mechanisms 17 may be symmetrically provided about the center line of the touch panel 12. Furthermore, in the embodiment of the present application, when the limiting mechanism 17 limits the position, the touch pad is not easily warped, and the force applied to the touch pad 12 and the housing 11 is more uniform.

For example, one stop mechanism 17 may be provided at each midpoint of the two short sides of the touchpad 12. Or, one limiting mechanism 17 may be disposed at a midpoint of each of the two short sides of the touch pad 12, and one limiting mechanism 17 may be disposed at a midpoint of each of the two long sides of the touch pad 12, which is not limited in this embodiment of the application.
