Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly to a touchpad and an electronic device. Background Art

[0002] As an input device, a touchpad can be applied to a series of electronic devices such as laptop computers and tablet computers. Currently, there is a problem that the pressing stroke is relatively large at the four corners and the edge regions of the touchpad, which is likely to have an adverse impact on the user experience. Summary of the Invention

[0003] The purpose of this application is to provide a touchpad and an electronic device to solve the problem that the pressing stroke is relatively large at the four corners and the edge regions of the touchpad in the above-mentioned prior art.

[0004] In the first aspect of this application, a touchpad is provided, which includes a fixed platform, a touch component, a shrapnel, and a trigger. The touch component is provided with a travel switch; the shrapnel includes a first connecting portion, a second connecting portion, and two elastic arms. The first connecting portion connects the elastic arms and the fixed platform so that the elastic arms can rotate around the first connecting portion, and the second connecting portion connects the elastic arms and the touch component; the trigger is arranged between the two elastic arms. When the touch component is pressed and the pressure acts on the shrapnel, the trigger can move towards the side close to the travel switch under the drive of each elastic arm to trigger the travel switch; wherein, each elastic arm includes two inner support arms, and each inner support arm is connected to the trigger.

[0005] In the embodiment of this application, the trigger and the travel switch can move towards each other, which makes a part of the moving stroke of the elastic structure in the pressing direction be the pressing stroke of the touchpad, and the other part is the upward moving stroke of the trigger. Such a design enables the touchpad to trigger the travel switch with a smaller pressing stroke, thereby achieving the purpose of reducing the pressing stroke of the touchpad, and further facilitating the improvement of the user experience. At the same time, since the pressing stroke of the touchpad is reduced, the gap generated between the touchpad and the second housing after being pressed is reduced, which is beneficial to reducing the possibility of the user's hand being scratched by the edge corners of the installation groove, and further improving the user experience. On the other hand, this also reduces the possibility of the components inside the electronic device being exposed to the outside through the gap between the touchpad and the second housing after the touchpad is pressed, which is beneficial to reducing the possibility of the internal components of the electronic device being contaminated by the outside, and further beneficial to ensuring the normal and stable operation of the electronic device.

[0006] In a possible implementation manner, the two inner support arms of each elastic arm extend towards the direction of approaching each other.

[0007] This design makes the force transmission path on the inner support arm closer to the connection path from the trigger to the corners of the elastic piece. Therefore, when the user presses on the four corners of the touchpad, the above setting method enables the force to be quickly and smoothly transmitted from the corners of the elastic piece to the trigger, so that the elastic piece can drive the trigger to move quickly and stably. This not only helps to improve the sensitivity of the four corners of the touchpad, but also helps to improve the pressing feel of the four corners.

[0008] In a possible implementation manner, the elastic piece further includes a mounting portion; the mounting portion is located between the two elastic arms and is respectively connected to each of the inner support arms; the trigger is mounted on the mounting portion.

[0009] By providing the mounting portion, it is beneficial to improve the stability of the trigger mounted on the elastic piece, thus facilitating the elastic piece to drive the trigger to move stably and reliably.

[0010] In a possible implementation manner, the mounting portion is provided with a mounting hole, and the trigger is mounted in the mounting hole.

[0011] The above design is beneficial to improve the stability of the trigger provided in the mounting portion.

[0012] In a possible implementation manner, the elastic piece further includes a third connecting portion; the two inner support arms of each elastic arm are both connected to the mounting portion through the third connecting portion.

[0013] By providing the third connecting portion, it is beneficial to achieve an elastic connection between the elastic arm and the mounting portion, and at the same time is also beneficial to achieve an elastic connection between the two elastic arms, so that the two elastic arms can drive the trigger to move through the mounting portion under an external force, thereby facilitating the trigger to trigger the travel switch.

[0014] In a possible implementation manner, the two inner support arms of each elastic arm are arranged in parallel.

[0015] This design is beneficial to reduce the possibility of stress concentration between each inner support arm and the corresponding outer support arm, thereby improving the stability of the entire structure of the elastic piece, and further facilitating the extension of the service life of the elastic piece.

[0016] In a possible implementation manner, the elastic piece further includes a connecting piece; along the width direction of the elastic piece, both ends of the connecting piece are connected to the inner support arms; the trigger is mounted on the connecting piece.

[0017] The connecting piece plays a connecting role between the two elastic arms and provides an installation space for the trigger, thereby facilitating the elastic arms to drive the trigger to move.

[0018] In a possible implementation manner, the connecting piece is provided with a mounting hole, and the trigger is mounted in the mounting hole.

[0019] The above design is beneficial to improving the stability of the trigger member disposed on the connecting piece.

[0020] In a possible implementation manner, the elastic piece further includes a third connecting portion; both of the inner support arms of each elastic arm are connected to the connecting piece through the third connecting portion.

[0021] By providing the third connecting portion, it is beneficial to achieve the elastic connection between the elastic arm and the connecting piece, and at the same time, it is also beneficial to achieve the elastic connection between the two elastic arms, so that the two elastic arms can drive the trigger member to move through the connecting piece under the action of an external force, thereby facilitating the trigger member to trigger the travel switch.

[0022] In a possible implementation manner, the elastic arm further includes an outer support arm; along the length direction of the elastic piece, one end of the outer support arm is respectively connected to the two inner support arms, and the other end is connected to the second connecting portion; the first connecting portion is located in the area surrounded by the outer support arm and the two inner support arms and is connected to the outer support arm.

[0023] The above design enables the outer support arm and the two inner support arms to form a "see-saw" structure, so that the elastic piece can drive the trigger member to move in the direction close to the travel switch when being pressed, thereby being beneficial to reducing the pressing stroke of the touch pad, and further being beneficial to improving the user experience. At the same time, in the embodiments of the present application, two inner support arms are provided on each elastic arm. When the elastic piece is pressed, the pressure can be transmitted through multiple inner support arms respectively, so that the multiple inner support arms drive the trigger member to move. Such a design increases the force transmission path, enables the force to be transmitted more evenly on the elastic piece, thereby being beneficial to improving the stress state of the elastic piece, and further enabling the elastic piece to drive the trigger member to move more stably and reliably, improving the reliability of the cooperation between the trigger member and the travel switch, thereby being beneficial to improving the sensitivity of the touch pad response, and at the same time, improving the pressing feel of the touch pad, and further being beneficial to improving the user experience.

[0024] In a possible implementation manner, the elastic piece includes two second connecting portions; along the width direction of the elastic piece, the two second connecting portions are respectively located at both ends of the outer support arm.

[0025] Such a design is beneficial to improving the pressing feel at the four corners of the touch pad, thereby being beneficial to improving the user experience. On the other hand, by providing multiple second connecting portions, it is beneficial to improving the connection stability between the elastic piece and the support member, thereby being beneficial to improving the reliability of the entire touch pad.

[0026] In a possible implementation manner, a notch is formed in the outer support arm; the notch is located between the two second connecting portions.

[0027] By providing a notch, it is beneficial to improve the deformation ability of the outer support arm, facilitating the deformation of the outer support arm under the action of external pressure, thereby enhancing the reliability of the entire elastomer's movement and enabling the touchpad to work stably. Meanwhile, such a design also helps to reduce the weight of the entire elastomer, which is conducive to the lightweight design of the touchpad and the entire electronic device.

[0028] In a possible implementation, the elastomer includes two of the first connecting portions; along the width direction of the elastomer, each of the first connecting portions is located between the two inner support arms.

[0029] By providing multiple first connecting portions, it is beneficial to improve the connection stability between the elastomer and the fixed platform and facilitate the stable and reliable rotation of the elastic arm. At the same time, by arranging the first connecting portions inside the two inner support arms, it is conducive to saving the space occupied by the elastomer in the touchpad.

[0030] In a possible implementation, the touchpad further includes a reinforcing sheet; the reinforcing sheet is connected to the elastomer.

[0031] The reinforcing sheet supports and reinforces the elastomer, thereby enhancing the strength and stiffness of the elastomer and prolonging its service life. Meanwhile, it also enables the force to be transmitted more effectively on the elastomer, facilitating the rotation of the elastic arm to drive the trigger member to move.

[0032] In a possible implementation, the reinforcing sheet includes a first reinforcing portion; the first reinforcing portion is connected to the elastic arm.

[0033] The elastic arm connected to the reinforcing sheet can be approximately regarded as a rod, with a relatively small deformation degree after being stressed, enabling the force to be effectively transmitted on the elastic arm, and thus facilitating the rotation of the elastic arm to drive the trigger member to move.

[0034] In a possible implementation, the reinforcing sheet further includes a second reinforcing portion; the elastomer includes a mounting portion, and the trigger member is mounted on the mounting portion, and the second reinforcing portion is connected to the mounting portion; or, the reinforcing sheet further includes a third reinforcing portion; the elastomer includes a connecting piece, and the trigger member is mounted on the connecting piece, and the third reinforcing portion is connected to the connecting piece.

[0035] By providing a reinforcing sheet on the mounting portion or the connecting piece, it is beneficial to improve the strength of the mounting portion, thereby enhancing the stability of the trigger member's installation and further improving the stability of the trigger member's movement.

[0036] In a possible implementation, the installation part is provided with an installation hole, the trigger member is installed in the installation hole, the second reinforcing part is provided with an avoidance hole, and the diameter of the avoidance hole is larger than the diameter of the installation hole; or, the connecting piece is provided with an installation hole, the trigger member is installed in the installation hole, the third reinforcing part is provided with an avoidance hole, and the diameter of the avoidance hole is larger than the diameter of the installation hole.

[0037] This design reduces the possibility of interference between the reinforcing piece and the trigger member on the one hand, and on the other hand, also enables the installation part or the connecting piece to retain a certain ability of elastic deformation, thus facilitating the up and down movement of the trigger member.

[0038] The second aspect of the present application provides an electronic device, including a housing and a touch panel, where the touch panel is the touch panel described in any one of the above, and the touch panel is installed on the housing.

[0039] Since the touch panel can achieve the above technical effects, the electronic device with this touch panel can also achieve the above technical effects, which will not be elaborated here.

[0087] The accompanying drawings here are incorporated into the description and form a part of this description, showing embodiments in line with this application, and are used together with the description to explain the principles of this application. Detailed implementation manners

[0088] In order to make the objectives, technical solutions and advantages of this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0089] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "a plurality of" means two or more; the terms "connection", "fixation", etc. should all be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0090] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0091] As an input device, a touchpad can be applied to a series of electronic devices such as laptops and tablets. The touchpad can provide a touch and press interface for users. It can sense the sliding and pressing actions of users' fingers, enabling the electronic device to make corresponding feedback. The touchpad can be regarded as performing the same function as a mouse.

[0092] Among them, the touchpad can be a full - area press touchpad, that is, users can perform press operations at any position on the touchpad. However, currently, as the touch area of the touchpad continues to increase, the problem of larger pressing strokes at the four corners and edge regions of the touchpad has gradually become prominent, which has a negative impact on the user experience. At the same time, as the pressing stroke of the touchpad increases, a large gap is generated between the touchpad and the housing of the electronic device after being pressed, resulting in the user's hand being prone to rubbing against the housing when operating the touchpad, which also affects the user experience.

[0093] In response to the above problems, as Figure 1 shown, an embodiment of the present application provides an electronic device 1000. The electronic device can be a terminal device such as a laptop or a tablet, or an input device such as a keyboard that can be used in conjunction with the above - mentioned terminal device. Here, taking the electronic device 1000 as a laptop as an example for specific description, the laptop includes a housing 100, a display screen 200, a keyboard 300, and a touchpad 400. The housing 100 includes a first housing 100a and a second housing 100b, which are rotatably connected. The display screen 200 is arranged on the first housing 100a, and the keyboard 300 and the touchpad 400 are arranged on the second housing 100b. Among them, an installation groove (not shown in the figure) can be formed on the second housing 100b, and the touchpad 400 is installed on the second housing 100b through this installation groove.

[0094] As Figure 2 shown, an embodiment of the present application also provides a touchpad 400, which is applied to the above - mentioned electronic device 1000. The touchpad 400 includes a support component 1, a touch component 2, and a trigger 3. The touch component 2 is for users to perform operations such as pressing and touching. The support component 1 is located below the touch component 2, and the trigger 3 is installed on the support component 1. The support component 1 supports the touch component 2 and provides a resilience force for the touch component 2, so that the touch component 2 can return to the initial state after the user cancels the pressing operation.

[0095] The touch component 2 is located at the top of the touchpad 400, and it can sequentially include a cover plate 22, a circuit board 23, and a travel switch 21 from top to bottom.

[0096] Among them, the cover plate 22 provides an interface for the user to touch and press. The circuit board 23 and the travel switch 21 are used to implement a series of functions such as sliding and clicking of the touchpad 400, and the trigger 3 is used to trigger the travel switch 21.

[0097] The specific working principle of the touch control component 2 is as follows: The travel switch 21 may include an elastic structure, and conduction points (not shown in the figure) may be provided on the circuit board 23. When the user does not press the cover plate 22, the elastic structure and the trigger 3 may be in a state of being in contact with each other or in a state of being separated from each other, and at this time, the elastic structure can be regarded as being in an initial state without deformation. When the user presses the cover plate 22, the travel switch 21 moves along the pressing direction together with the cover plate 22 and the circuit board 23. At this time, the elastic structure is subjected to pressure and contacts the trigger 3 and deforms. The deformed elastic structure can contact the conduction points on the circuit board 23, so as to be conducted with the circuit board 23. At this time, the travel switch 21 is triggered, so that the electronic device 1000 can make corresponding feedback according to the pressing action of the user on the touchpad 400.

[0098] When the user cancels the pressing of the cover plate 22, the above-mentioned elastic structure can return to the initial state under the action of the elastic force. At this time, the elastic structure is separated from the conduction points, so that the circuit between the travel switch 21 and the circuit board 23 is disconnected, and at this time, the travel switch 21 returns to the untriggered state. The moving stroke of the above-mentioned elastic structure in the pressing direction can be understood as the stroke required to trigger the travel switch 21. Specifically, the above-mentioned travel switch 21 can be a Dome key, and the elastic structure can be a kind of metal dome sheet.

[0099] In some embodiments, the above-mentioned trigger 3 can be a block structure, and the surface of the trigger 3 facing the travel switch 21 can be a plane, so that the trigger 3 can stably and reliably contact the travel switch 21 and trigger the travel switch 21.

[0100] In other embodiments, the above-mentioned trigger 3 can be an adjusting screw, and a nut (not shown in the figure) cooperating with the adjusting screw is also installed on the support assembly 1. The adjusting screw is installed on the support assembly 1 through the nut. When the adjusting screw is rotated, the adjusting screw can move up and down to adjust the distance between the trigger 3 and the travel switch 21, so that the trigger 3 can better cooperate with the travel switch 21. Such a design is beneficial to improving the sensitivity of the travel switch 21 and beneficial to improving the pressing feel of the touchpad 400, and further beneficial to improving the user's operation experience.

[0101] The support component 1 includes a fixed platform 11 and an elastic piece 12. The fixed platform 11 can be a fixed component disposed in the second housing 100b, such as a frame. Components such as the touch control component 2 and the elastic piece 12 are mounted into the second housing 100b through the fixed platform 11. The elastic piece 12 is located between the fixed platform 11 and the touch control component 2, and is respectively connected to the fixed platform 11 and the touch control component 2. The trigger 3 is mounted on the elastic piece 12. The elastic piece 12 can undergo elastic deformation, and its material can be metal or metal alloy.

[0102] When the user presses the touch control component 2, the cover plate 22, the circuit board 23, and the travel switch 21 move together along the pressing direction. This pressure is transmitted to the elastic piece 12, causing the elastic piece 12 to deform itself. Since a part of the elastic piece 12 is connected to the fixed platform 11, it can be understood that the fixed platform 11 provides a fulcrum for the elastic piece 12, enabling the elastic piece 12 to rotate around this fulcrum under the action of the pressure.

[0103] Specifically, one end of the elastic piece 12 connected to the touch control component 2 can rotate downward together with the touch control component 2, while the end of the elastic piece 12 connected to the trigger 3 can rotate upward, that is, the elastic piece 12 drives the trigger 3 to rotate toward the side close to the travel switch, so that the trigger 3 triggers the travel switch 21. When the user cancels the pressing operation, the elastic piece 12 loses the action of the pressure and can return to the initial state under the action of its own elastic force, thereby driving the touch control component 2 and the trigger 3 back to the initial positions respectively.

[0104] The support component 1 may further include a support member 13. The support member 13 is located between the touch control component 2 and the elastic piece 12, and the support member 13 connects the touch control component 2 and the elastic piece 12. When the user presses the cover plate 22, the pressure applied by the user can be transmitted to the elastic piece 12 through the support member 13, thereby causing the elastic piece 12 to undergo corresponding deformation. The support member 13 not only supports the touch control component 2, but at the same time, the support member 13 also plays an isolation role between the touch control component 2 and the elastic piece 12, thereby reducing the possibility of interference between the elastic piece 12 and the touch control component 2 when the elastic piece 12 deforms. The material of the support member 13 can be metal or metal alloy, such as iron or iron alloy, to provide reliable support for the touch control component 2, thereby contributing to improving the overall strength of the touch panel 400.

[0105] As Figure 3 shown, the cover plate 22 can be a rectangular sheet-like structure, and its surface can have good flatness, so as to facilitate the user to perform operations such as touching and clicking, thereby improving the user experience. The cover plate 22 can be made of a material with relatively high stiffness, such as glass, ceramic, or some other composite materials, thereby contributing to improving the overall stiffness and strength of the touch panel 400.

[0106] The circuit board 23 can also be a rectangular sheet-like structure, which can be a printed circuit board. The circuit board 23 is located on the lower surface of the cover plate 22 and can be connected to the cover plate 22 by means of adhesion. When the user presses the cover plate 22, the circuit board 23 can move together with the cover plate 22.

[0107] The travel switch 21 is arranged on the lower surface of the circuit board 23. Specifically, the travel switch 21 can be fixed in the central area of the circuit board 23 by means of adhesion.

[0108] The support member 13 can be a frame-like structure, which can be in the shape of a "square".

[0109] For the convenience of understanding, the length direction of the elastic sheet 12 is defined as the X-axis direction, the width direction of the elastic sheet 12 is defined as the Y-axis direction, and the thickness direction of the elastic sheet 12 is defined as the Z-axis direction.

[0110] Along the thickness direction Z of the elastic sheet 12, the support member 13 is located on the side of the circuit board 23 away from the cover plate 22, and the upper surface of the support member 13 can be connected to the lower surface of the circuit board 23 by means of adhesion. Along the length direction X of the elastic sheet 12, the support member 13 includes a first side 131 and a second side 132. The lower surfaces of the first side 131 and the second side 132 are respectively connected to the elastic sheet 12. Since the support member 13 is a frame-like structure, the inside thereof provides a space for the deformation of the elastic sheet 12, thereby reducing the possibility of interference between the elastic sheet 12 and the support member 13 and the touch control assembly 2.

[0111] The elastic sheet 12 is located between the support member 13 and the fixed platform 11. There is a protruding fixed point 111 on the fixed platform 11, and the elastic sheet 12 is connected to the fixed point 111. The elastic sheet 12 includes two elastic arms 121, which are respectively a first elastic arm 121A and a second elastic arm 121B. The first elastic arm 121A and the second elastic arm 121B are arranged along the length direction X of the elastic sheet 12 and are symmetrically arranged. The trigger member 3 is arranged between the first elastic arm 121A and the second elastic arm 121B. Both the first elastic arm 121A and the second elastic arm 121B are connected to the corresponding fixed point 111. Therefore, after the elastic sheet 12 is subjected to a pressure, both the first elastic arm 121A and the second elastic arm 121B can rotate with the fixed point 111 as the fulcrum, thereby driving the trigger member 3 to move towards the side close to the travel switch 21.

[0112] Along the thickness direction Z of the elastic piece 12, a reinforcing piece 14 can also be connected to one side of the elastic piece 12. The material of the reinforcing piece 14 can be metal or metal alloy, and its strength and hardness can be greater than those of the elastic piece 12. The reinforcing piece 14 can be welded to the elastic piece 12. The reinforcing piece 14 plays a role in supporting, reinforcing and strengthening the elastic piece 12, which is beneficial to improving the strength and stiffness of the elastic piece 12 and is beneficial to extending the service life of the elastic piece 12. At the same time, it also enables the force to be transmitted more effectively on the elastic piece 12, which is beneficial to realizing the rotation of the elastic arm 121 and driving the trigger 3 to move.

[0113] As Figure 4 shown, the elastic piece 12 can include a first connecting portion 122. At the same time, referring to Figure 3 , the elastic arm 121 is connected to the fixing point 111 of the fixed platform 11 through the first connecting portion 122. By providing the first connecting portion 122, it is beneficial to realize the elastic connection between the elastic arm 121 and the fixed platform 11, so that the elastic arm 121 can rotate relative to the fixed platform 11 under the action of an external force.

[0114] Continuing as Figure 4 shown, the elastic piece 12 can also include a second connecting portion 123. At the same time, referring to Figure 3 , the elastic arm 121 is connected to the support member 13 through the second connecting portion 123. By providing the second connecting portion 123, it is beneficial to realize the elastic connection between the elastic arm 121 and the support member 13, so that the elastic arm 121 can rotate relative to the support member 13 under the action of an external force.

[0115] Continuing as Figure 4 shown, the elastic piece 12 can also include a third connecting portion 124. At the same time, referring to Figure 3 , the elastic arm 121 is connected to the trigger 3 through the third connecting portion 124. By providing the third connecting portion 124, it is beneficial to realize the elastic connection between the elastic arm 121 and the trigger 3, that is, it is beneficial to realize the elastic connection between the two elastic arms 121, so that the two elastic arms 121 can drive the trigger 3 to move simultaneously under the action of an external force, which is beneficial to the trigger 3 to trigger the travel switch 21.

[0116] The following takes the first elastic arm 121A as an example for specific description. Please refer to Figure 3 and Figure 4, along the length direction X of the elastic piece 12, the outer end of the first elastic arm 121A is connected to the first side 131 of the support member 13 through the second connecting portion 123, the inner end of the first elastic arm 121A is connected to the trigger member 3 through the third connecting portion 124, and the middle portion of the first elastic arm 121A is connected to the fixed point 111 of the fixed platform 11 through the first connecting portion 122. At this time, the first elastic arm 121A can be understood as a "see-saw" structure erected on the fixed platform 11, and the portion where the first connecting portion 122 is connected to the fixed platform 11 can be understood as the fulcrum of this "see-saw" structure.

[0117] As Figure 5 shown, when the user presses the cover plate 22, the pressure will be transmitted from the first side 131 of the support member 13 to the outer side of the first elastic arm 121A. Under the action of the pressure, the outer side of the first elastic arm 121A will rotate downward with the first connecting portion 122 as the fulcrum, that is, move to the side away from the cover plate 22. Correspondingly, the inner side of the first elastic arm 121A will rotate upward with the first connecting portion 122 as the fulcrum, that is, move to the side close to the cover plate 22, so that the first elastic arm 121A can drive the trigger member 3 to move to the side close to the travel switch 21.

[0118] Similar to the first elastic arm 121A, the second elastic arm 121B can also be understood as a "see-saw" structure erected on the fixed platform 11. The outer end of the second elastic arm 121B is connected to the second side 132 of the support member 13 through the second connecting portion 123, the inner end of the second elastic arm 121B is connected to the trigger member 3 through the third connecting portion 124, and the middle portion of the second elastic arm 121B is connected to the fixed platform 11 through the first connecting portion 122. Therefore, when the user presses the cover plate 22, the first elastic arm 121A and the second elastic arm 121B can simultaneously drive the trigger member 3 to move to the side close to the travel switch 21.

[0119] As Figure 6 shown, in the related art, the inner end of the upper elastic arm 121' of the elastic piece is connected to the fixed platform 11', and the outer end of the elastic arm 121' is connected to the touch control component 2'. The elastic arm 121' in the related art can be understood as a "cantilever beam" structure erected on the fixed platform 11', and the outer end of the elastic arm 121' can rotate around its inner end after being pressed. The travel switch 21' is usually arranged in the central area of the touch panel 400', and the trigger member 3' is fixed on the fixed platform 11'.

[0120] When the user presses the touch component 2', the travel switch 21' moves downward along the pressing direction with the cover plate 22' and the circuit board 23' to enable the triggering member 3' to trigger the travel switch 21'. Such a design makes the moving stroke of the elastic structure in the pressing direction in the travel switch 21' (i.e., the stroke required to trigger the travel switch 21') the pressing stroke of the touchpad 400'. Since the travel switch 21' is located in the central area of the touchpad 400', when the pressing position of the touchpad 400' is at its corner, the distance between this position and the travel switch 21' is relatively far, so the stroke required to activate the travel switch 21' is relatively large, that is, the pressing stroke of the touchpad 400' is relatively large, thus bringing a poor operation experience to the user.

[0121] In the embodiment of the present application, the elastic arm 121 is set as the above-mentioned "seesaw" structure, and one end of the elastic arm 121 is connected to the triggering member 3, so that the elastic arm 121 can drive the triggering member 3 to move toward the side close to the travel switch 21 after being pressed. In the embodiment of the present application, the triggering member 3 and the travel switch 21 can move toward each other, which makes a part of the moving stroke of the elastic structure in the pressing direction the pressing stroke of the touchpad 400, and the other part is the upward moving stroke of the triggering member 3. Such a design enables the travel switch 21 to be triggered with a smaller pressing stroke of the touchpad 400, thus achieving the purpose of reducing the pressing stroke of the touchpad 400, and further facilitating the improvement of the user experience.

[0122] At the same time, since the pressing stroke of the touchpad 400 is reduced, the gap generated between the touchpad 400 and the second housing 100b after being pressed is reduced, which is conducive to reducing the possibility of the user's hand being scratched by the edge corners of the installation groove, and further improving the user's operation experience. On the other hand, this also reduces the possibility that the components inside the electronic device 1000 are exposed to the outside through the gap between the touchpad 400 and the second housing 100b after the touchpad 400 is pressed, which is conducive to reducing the possibility that the components inside the electronic device 1000 are contaminated by the outside, and further conducive to ensuring the normal and stable operation of the electronic device 1000.

[0123] As Figure 4 shown, in the embodiment of the present application, each elastic arm 121 can include an outer branch arm 121b and two inner branch arms 121a. Along the length direction X of the elastic piece 12, one end of each inner branch arm 121a is connected to the outer branch arm 121b, and the other end is connected to the triggering member 3 through the third connecting portion 124.

[0124] When the elastic sheet 12 is under pressure, the outer support arm 121b can rotate around the first connection part 122 to the side away from the cover plate 22, while the inner support arm 121a can rotate around the first connection part 122 to the side close to the cover plate 22, so as to drive the trigger member 3 to move towards the direction close to the travel switch 21. That is, the above design enables the outer support arm 121b and the two inner support arms 121a to form a "see-saw" structure, so that when the elastic sheet 12 is pressed, it can drive the trigger member 3 to move towards the direction close to the travel switch 21, which is beneficial to reducing the pressing stroke of the touch pad 400 and improving the user experience.

[0125] When the user presses the four corners of the touch pad 400, the elastic sheet 12 is prone to uneven force, which easily affects the stability and reliability of the movement of the trigger member 3, resulting in problems such as insensitive response at the four corners of the touch pad 400 and poor pressing feel. Considering this problem, in the embodiment of the present application, two inner support arms 121a are provided on each elastic arm 121. When the elastic sheet 12 is pressed, the pressure can be transmitted through multiple inner support arms 121a respectively, so that the multiple inner support arms 121a drive the trigger member 3 to move. This design increases the force transmission path, enables the force to be transmitted more evenly on the elastic sheet 12, which is beneficial to improving the force-bearing state of the elastic sheet 12, and further enables the elastic sheet 12 to drive the trigger member 3 to move more stably and reliably, improving the reliability of the cooperation between the trigger member 3 and the travel switch 21, which is beneficial to improving the sensitivity of the response of the touch pad 400, and at the same time improving the pressing feel of the touch pad 400, and further beneficial to improving the user experience.

[0126] In the related art, rotating parts such as rotating shafts and hinges are provided between the outer support arm and the inner support arm to realize the rotation between the outer support arm and the inner support arm. Such a design has high requirements for the assembly accuracy between the outer support arm, the inner support arm and the rotating parts. If the assembly accuracy cannot meet the use requirements of the touch pad, a series of problems such as insensitive movement of the outer support arm and the inner support arm are likely to occur. Moreover, as the number of times the user presses increases, the reliability of the rotating parts gradually decreases, which easily leads to the touch pad being unable to work properly, thus affecting the use of the entire electronic device.

[0127] In the touchpad 400 provided by the embodiment of the present application, the elastic sheet 12 includes a first elastic arm 121A, a second elastic arm 121B, a first connecting portion 122, a second connecting portion 123, and a third connecting portion 124. Among them, the first elastic arm 121A, the second elastic arm 121B, the first connecting portion 122, the second connecting portion 123, and the third connecting portion 124 can form the elastic sheet 12 by an integral molding method. The elastic sheet 12 realizes the rotation of the outer arm 121b and the inner arm 121a through its own deformation, making the movement of the entire elastic arm 121 more stable and reliable. Thereby, it is beneficial to improve the stability of the movement of the trigger member 3, so as to improve the stability of the cooperation between the trigger member 3 and the travel switch 21, and further beneficial to improve the reliability of the touchpad 400, making the touchpad 400 more sensitive in response and having a better pressing feel, so that it can bring a better user experience to the user. At the same time, the reliability of the elastic sheet 12 itself is relatively high, which is beneficial to extend the service life of the touchpad 400. On the other hand, the structure of the elastic sheet 12 is simple, and its molding method can simplify the production and manufacturing process, which is beneficial to improve the production efficiency of the touchpad 400. In addition, since no additional components are required, it is beneficial to save the overall space of the touchpad 400 and facilitate the further thinning of the electronic device 1000.

[0128] As can be seen from the above, in the embodiment of the present application, the elastic sheet 12 realizes the rotation of the outer arm 121b and the inner arm 121a through its own deformation. When the external force applied by the user reaches a certain level, the deformation of the elastic sheet 12 will reach the limit, thereby restricting the outer arm 121b and the inner arm 121a, making the two unable to continue rotating under the user's pressing, which plays a role in restricting the pressing stroke of the touchpad 400. This is beneficial to reducing the possibility that the pressing stroke of the touchpad 400 increases due to the user pressing the touchpad 400 forcefully, thereby further improving the user's operation experience.

[0129] As Figure 4 shown, along the length direction X of the elastic sheet 12, one end of the above-mentioned outer arm 121b is respectively connected to the two inner arms 121a, and the other end is connected to the second connecting portion 123. At the same time, referring to Figure 3 shown, specifically, the outer arm 121b of the first elastic arm 121A is connected to the first side 131 of the support member 13 through the corresponding second connecting portion 123, and the outer arm 121b of the second elastic arm 121B is connected to the second side 132 of the support member 13 through the corresponding second connecting portion 123.

[0130] Continuing as Figure 4As shown in the figure, two second connection parts 123 can be arranged on each outer support arm 121b. Along the width direction Y of the elastic piece 12, the two second connection parts 123 are respectively located at both ends of the outer support arm 121b. A total of four second connection parts 123 can be arranged on the two elastic arms 121, and the four second connection parts 123 respectively correspond to the four corners of the touch panel 400. Such a design is beneficial to improving the pressing feel of the four corners of the touch panel 400, thereby being beneficial to improving the user experience. On the other hand, by arranging multiple second connection parts 123, it is beneficial to improve the connection stability between the elastic piece 12 and the support member 13, thereby being beneficial to improving the reliability of the entire touch panel 400.

[0131] A notch 121c is formed on the outer support arm 121b along the thickness direction Z of the elastic piece 12. Along the width direction Y of the elastic piece 12, the notch 121c is located between the two second connection parts 123. By arranging the notch 121c, it is beneficial to improve the deformation ability of the outer support arm 121b, facilitating the deformation of the outer support arm 121b under the action of external pressure, thereby being beneficial to improving the reliability of the operation of the entire elastic piece 12 to achieve stable operation of the touch panel 400. At the same time, such a design is also beneficial to reducing the weight of the entire elastic piece 12, thereby being beneficial to the lightweight design of the touch panel 400 and the entire electronic device 1000.

[0132] The first connection part 122 is also connected to the outer support arm 121b, and the first connection part 122 is located in the area enclosed by the outer support arm 121b and the two inner support arms 121a. Each outer support arm 121b is connected to the fixed platform 11 through the corresponding first connection part 122.

[0133] As can be seen from the above, the elastic arm 121 in the embodiment of the present application can be understood as a "see - saw" structure erected on the fixed platform 11, and the first connection part 122 plays the role of a fulcrum for the elastic arm 121. The position of the first connection part 122 can be adjusted according to the size of the touch area of the touch panel 400 to better achieve the effect of reducing the pressing stroke of the four corners of the touch panel 400.

[0134] Two first connection parts 122 can be arranged on each outer support arm 121b. Along the width direction Y of the elastic piece 12, the two first connection parts 122 are located between the two inner support arms 121a and can be arranged at intervals. By arranging the first connection part 122 inside the two inner support arms 121a, it is beneficial to save the space occupied by the elastic piece 12 in the touch panel 400. At the same time, by arranging multiple first connection parts 122, it is beneficial to improve the connection stability between the elastic piece 12 and the fixed platform 11 and is beneficial to realizing the stable and reliable rotation of the elastic arm 121.

[0135] The shrapnel 12 may include a mounting portion 125. Along the length direction X of the shrapnel 12, the mounting portion 125 is located between the first elastic arm 121A and the second elastic arm 121B. Each inner support arm 121a is connected to the mounting portion 125 through a third connecting portion 124. Among them, the mounting portion 125 is provided with a mounting hole 126, and the trigger member 3 is installed in the mounting hole 126. By providing the mounting portion 125, it is beneficial to improve the stability of the installation of the trigger member 3 on the shrapnel 12, thereby facilitating the shrapnel 12 to drive the trigger member 3 to move stably and reliably. Among them, the mounting hole 126 is provided on the mounting portion 125, which is beneficial to improve the stability of the trigger member 3 arranged on the mounting portion 125.

[0136] Continue as Figure 4 shown. In a possible implementation manner, the two inner support arms 121a of each elastic arm 121 extend in a direction close to each other, that is, along the width direction Y of the shrapnel 12, the distance between the two inner support arms 121a gradually decreases in the direction close to the trigger member 3. Since the first elastic arm 121A and the second elastic arm 121B are symmetrically arranged, the two inner support arms 121a of the first elastic arm 121A and the two inner support arms 121a of the second elastic arm 121B can form an "X" - shaped structure, and the trigger member 3 is located at the intersection of each inner support arm 121a. In this implementation manner, the trigger member 3 is located in the central area of the shrapnel 12, and each inner support arm 121a is inclined, so that the force transmission path on the inner support arm 121a is closer to the connection path from the trigger member 3 to each corner of the shrapnel 12. Therefore, when the user presses the four corners of the touchpad 400, the above - mentioned setting method enables the force to be quickly and smoothly transmitted from the corners of the shrapnel 12 to the trigger member 3, so that the shrapnel 12 can drive the trigger member 3 to move quickly and stably. This not only helps to improve the sensitivity of the four - corner response of the touchpad 400, but also helps to improve the pressing feel of the four corners.

[0137] As Figure 7 shown, in the above - mentioned implementation manner, the reinforcing piece 14 can selectively reinforce the shrapnel 12. Among them, the reinforcing piece 14 may include a first reinforcing portion 141 and a second reinforcing portion 142. At the same time, refer to Figure 4, the first reinforcing portion 141 is provided on the elastic arm 121, and no reinforcing piece 14 is provided on the first connecting portion 122, the second connecting portion 123, and the third connecting portion 124. The elastic arm 121 connected with the reinforcing piece 14 can be approximately regarded as a rod, and its deformation degree after being stressed is small, so that the force can be effectively transmitted in the elastic arm 121, which is conducive to realizing the rotation of the elastic arm 121 to drive the trigger member 3 to move. Since no reinforcing piece 14 is provided on the first connecting portion 122, the second connecting portion 123, and the third connecting portion 124, the three can still undergo large elastic deformation, thereby realizing the elastic connection between the elastic arm 121 and the fixed platform 11, between the elastic arm 121 and the support member 13, and between the two elastic arms 121, so that the elastic arm 121 can rotate under the action of an external force. The second reinforcing portion 142 can be an annular structure, and it is provided on the mounting portion 125. By providing the second reinforcing portion 142 on the mounting portion 125, it is beneficial to improve the strength of the mounting portion 125, which is conducive to improving the stability of the installation of the trigger member 3, and further conducive to improving the stability of the movement of the trigger member 3.

[0138] An avoidance hole 144 can be formed in the second reinforcing portion 142, and the diameter of the avoidance hole 144 is larger than the diameter of the above-mentioned mounting hole 126. Such a design reduces the possibility of interference between the second reinforcing portion 142 and the trigger member 3 on the one hand, and on the other hand, such a design also enables the mounting portion 125 to retain a certain ability of elastic deformation, thereby facilitating the up and down movement of the trigger member 3.

[0139] As Figure 8 shown, in another possible implementation manner, the inner support arms 121a of the elastic arms 121 are arranged parallel to each other, that is, the inner support arms 121a of the first elastic arm 121A and the second elastic arm 121B can enclose a "mouth" - shaped structure. Among them, the included angle between the inner support arm 121a and the corresponding outer support arm 121b can be 90°. Such a design is beneficial to reducing the possibility of stress concentration between the inner support arm 121a and the corresponding outer support arm 121b, thereby improving the stability of the entire structure of the elastic piece 12, and further conducive to extending the service life of the elastic piece 12.

[0140] Along the width direction Y of the elastic piece 12, there is a connecting piece 127 between the first elastic arm 121A and the second elastic arm 121B. Each inner support arm 121a is connected to the connecting piece 127 through the third connecting portion 124, and each inner support arm 121a and the connecting piece 127 can form an "I" - shaped structure. A mounting hole 126 is formed in the connecting piece 127, and the trigger member 3 is mounted in the mounting hole 126. The connecting piece 127 plays a connecting role between the first elastic arm 121A and the second elastic arm 121B and provides an installation space for the trigger member 3, which is conducive to the elastic arm 121 driving the trigger member 3 to move.

[0141] The connecting piece 127 may be provided with mounting holes 126, which is conducive to improving the stability of the trigger 3 arranged on the connecting piece 127.

[0142] As Figure 9 shown, in the above embodiment, the reinforcing piece 14 may also selectively reinforce the elastic piece 12. The reinforcing piece 14 may include a first reinforcing portion 141 and a third reinforcing portion 143. At the same time, referring to Figure 8 , the first reinforcing portion 141 is arranged on the elastic arm 121 so that the force can be effectively transmitted on the elastic arm 121, which is conducive to realizing the rotation of the elastic arm 121 to drive the trigger 3 to move. The first connecting portion 122, the second connecting portion 123 and the third connecting portion 124 are not provided with the reinforcing piece 14. Therefore, the three can still undergo large elastic deformations, so as to realize the elastic connection between the elastic arm 121 and the fixed platform 11, between the elastic arm 121 and the support member 13, and between the two elastic arms 121, so that the elastic arm 121 can rotate under the action of an external force. The third reinforcing portion 143 is connected to the connecting piece 127 to improve the strength of the connecting piece 127, which is conducive to improving the stability of the installation of the trigger 3.

[0143] The third reinforcing portion 143 may be provided with an avoidance hole 144, and the diameter of the avoidance hole 144 is larger than the diameter of the mounting hole 126. Such a design reduces the possibility of interference between the third reinforcing portion 143 and the trigger 3 on the one hand. On the other hand, such a design enables the connecting piece 127 to retain a certain ability of elastic deformation at the connection part with the trigger 3, so as to facilitate the up and down movement of the trigger 3.

[0144] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
