Description

Technical Field

[0001] The present invention relates to the field of touch control technology of electronic equipment, and in particular to a touch panel key module and a touch panel module. Background Art

[0002] The booming development of electronic devices has brought a lot of convenience to people's lives, and people are pursuing higher and higher user experience. Take the common laptops in daily life as an example. Laptops are equipped with touchpads to control the cursor without setting up a mouse, thereby improving the portability of laptops, reducing the difficulty of users carrying devices, and providing great convenience for remote work.

[0003] The touchpad of a laptop computer has two buttons on the left and right, and the trigger points of the left and right buttons are at the center of the two buttons. When the touchpad is pressed, the touchpad is slightly deformed so that the trigger point on it contacts the trigger point fixed on the bottom shell below to achieve triggering. However, as the use time increases, problems such as deformation of the touchpad or unstable electrical connection at the corners of the left and right buttons may occur, which may lead to problems such as too long pressing stroke or even ineffective pressing when pressing on the corners of the left and right buttons. The current method to solve the aforementioned problem is to increase the strength of the touchpad by adding springs or balance bars to counteract deformation of the touchpad due to pressing, but it has not been able to more effectively solve the problems of too long pressing stroke and insensitivity caused by deformation of the touchpad.

[0004] Therefore, it is necessary to provide a touchpad button module and a touchpad module that can effectively solve the problems of too long pressing stroke and insensitivity caused by deformation of the touchpad, so as to solve the above technical problems. Summary of the invention

[0005] An object of the present invention is to provide a touch panel key module which can effectively solve the problems of too long pressing stroke and insensitivity caused by deformation of the touch panel.

[0006] Another object of the present invention is to provide a touch panel module that can effectively solve the problems of too long pressing stroke and insensitivity caused by deformation of the touch panel.

[0007] To achieve the above-mentioned purpose, the technical solution of the present invention is: to provide a touchpad button module, which includes a base, at least two main wave levers and a secondary wave lever; wherein the middle part of each of the main wave levers is pivotally connected to the base; the secondary wave lever is arranged between the main wave levers and is respectively pivotally connected to one end of each of the main wave levers; when one end of each of the main wave levers away from the secondary wave lever is subjected to force, the main wave lever pivots compared to the base and drives the secondary wave lever to move up and down compared to the base.

[0008] Preferably, a rotating shaft is convexly provided at the middle of each main wave lever, a mounting hole corresponding to each main wave lever is provided on the base, a mounting groove is provided on the side wall of the mounting hole, each main wave lever is correspondingly accommodated in one mounting hole and the rotating shaft is pivotally connected to the mounting groove. Therefore, when the end of the main wave lever away from the secondary wave lever is subjected to force, the main wave lever will rotate with its rotating shaft as a fulcrum, so that the end pivotally connected to the secondary wave lever pushes the secondary wave lever, so that the secondary wave lever moves upward to trigger the touch panel, so that when the corner of the touch panel is subjected to force, it can also ensure rapid triggering.

[0009] Preferably, the end of each main wave lever away from the auxiliary wave lever is a force-bearing end, and the force-bearing end protrudes above the base. In this way, when a corner of the touch panel is subjected to a small force, it can act on the force-bearing end, thereby causing the other end of the touch panel to push the auxiliary wave lever upward and contact the trigger plate, thereby ensuring the sensitivity of the trigger.

[0010] Preferably, the force-bearing end of each main wave lever is provided with a protrusion, and the protrusion protrudes above the base. When a small force is applied to the corner of the touch panel, the protrusion can be acted on, thereby causing the other end of the main wave lever to push the auxiliary wave lever upward to trigger the touch panel and ensure the sensitivity of the trigger.

[0011] Preferably, one end of each main wave lever adjacent to the secondary wave lever is a connecting end, and the connecting end is provided with a connecting shaft, the axial direction of the connecting shaft is the same as the axial direction of the rotating shaft of the main wave lever, and the connecting shaft is pivotally connected to the secondary wave lever, so that the pivot connection between the main wave lever and the secondary wave lever is simple.

[0012] Preferably, the auxiliary wave lever comprises a connecting plate and a first slot provided on a side of the connecting plate, each of the first slots is engaged with an outside of the connecting shaft and is pivotally connected to the connecting shaft, so that the pivot connection between the main wave lever and the auxiliary wave lever is simple.

[0013] Preferably, a clamping claw is protrudingly provided on one side surface of the connecting plate, and the opposite surfaces of each pair of the clamping claws are provided with clamping surfaces with an arc-shaped structure, the first slot is formed between the clamping surfaces of each pair of the clamping claws, and the ends of each pair of the clamping claws are spaced apart to form a clamping entrance connected to the first slot, and the connecting shaft is inserted into the first slot through the clamping entrance and pivotally connected to the first slot, so that the pivot connection between the main wave lever and the auxiliary wave lever is simple.

[0014] Preferably, a second slot is further provided in the middle of the secondary wave lever, and a connecting seat is provided on the base. The secondary wave lever is movably supported outside the connecting seat through the second slot. When the main wave lever pivots and applies force to the secondary wave lever, the secondary wave lever moves upward compared to the connecting seat, thereby being able to stably trigger the trigger plate.

[0015] Preferably, the connecting seat is a rod-shaped structure, and the axial direction of the connecting seat is consistent with the axial direction of the main wave rod, and the second slot is connected to the connecting seat so that the auxiliary wave rod can move relative to the connecting seat.

[0016] Preferably, a trigger portion is protruding from a side surface of the connecting plate away from the first card slot, so that when the auxiliary wave lever is subjected to a small push force, the trigger portion above it can act on the touch panel, making the trigger more sensitive and providing electrical connectivity and pressing feel.

[0017] Preferably, the touchpad button module includes two main wave levers, the base is provided with two mounting holes extending in the same direction, a connecting seat is provided between the two mounting holes, each main wave lever is pivotally connected to one mounting hole, the auxiliary wave lever is engaged outside the connecting seat and its two ends are pivotally connected to the two main wave levers.

[0018] Correspondingly, the present invention also provides a touchpad module, which includes a touchpad and the touchpad button module as described above; wherein, a trigger button is convexly provided on the touchpad, the touchpad button module is arranged below the touchpad, and a trigger part corresponding to the trigger button is convexly provided on the sub-wavelength lever, and the trigger part is in contact with the trigger button.

[0019] Compared with the prior art, the touchpad key module of the present invention pivots at least two main wave levers on the base, so that each main wave lever forms a lever, and a secondary wave lever is arranged between each main wave lever, and the secondary wave lever is pivoted to one end of each main wave lever, so that when the end of each main wave lever away from the secondary wave lever is subjected to force, the main wave lever pivots relative to the base and drives the secondary wave lever to move upward relative to the base, so that the secondary wave lever contacts the touchpad to achieve triggering. In this way, even if the touchpad is deformed or pressed to the corner or edge of the touchpad, the touchpad can be quickly triggered, solving the problem of invalid triggering caused by deformation of the touchpad and other reasons in the prior art. Secondly, the lever formed by the main wave lever is used to compensate for the pressing stroke, which can not only effectively compensate for the problem of too long pressing stroke caused by deformation of the touchpad and other reasons, but also ensure that the edge or corner of the touchpad can be triggered when pressed, and only a small pressing force is required to trigger, making the trigger more sensitive and increasing the pressing feel. Furthermore, by flexibly setting the fulcrum position between the main wave lever and the base, different pressing force values ​​and pressing stroke requirements can be met, thereby effectively controlling the pressing stroke at the corner position of the key. In addition, the main wave lever and the auxiliary wave lever have simple structures and can be made of all plastic, thereby reducing production costs and thus reducing overall costs.

[0020] Correspondingly, the touch panel module having the touch panel key module of the present invention also has the above technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

The first, second, etc. described are only used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0046] Combination Figure 1-Figure 17As shown, the touch panel button module 100 provided by the present invention is applicable to an electronic device 1 having a touch panel 200 to solve the problems of too long pressing stroke and ineffective pressing caused by deformation of the touch panel 200 and the like.

[0047] In the present invention, the electronic device 1 refers to consumer electronic products, such as laptop computers, tablet computers, etc., but is not limited thereto. The electronic device 1 may also be various handheld devices with touch panels, vehicle-mounted devices, wearable devices, computing devices, and various forms of user equipment (UE), mobile stations (MS), terminal devices, etc., which are not specifically limited in this application.

[0048] Let's combine Figure 1-Figure 8 As shown, in one embodiment of the present invention, the touchpad key module 100 includes a base 110, at least two main wave levers 120 and a secondary wave lever 130. The middle part of each main wave lever 120 is pivotally connected to the base 110, so that each main wave lever 120 forms a lever. The secondary wave lever 130 is arranged between each main wave lever 120 and pivotally connected to one end of each main wave lever 120, and the secondary wave lever 130 is used to contact with the touchpad 200 (described later) to achieve triggering. With this structural arrangement, when a force is applied to one end of each main wave lever 120 away from the secondary wave lever 130, the main wave lever 120 can be pivoted relative to the base 110, so that one end of the main wave lever 120 pivotally connected to the secondary wave lever 130 can move up and down relative to the base 110, thereby driving the secondary wave lever 130 to move up and down relative to the base 110, so that the secondary wave lever 130 can stably contact the touch panel 200 to achieve triggering, and by forming a stroke compensation of the main wave lever 120 of the lever, only a small force is needed to press the touch panel 200 to move the main wave lever 120 by a small stroke, so as to drive the secondary wave lever 130 to move upward to achieve triggering, thereby effectively compensating for the excessively long pressing stroke caused by deformation of the touch panel 200 and ensuring that the edge or corner of the touch panel 200 can be triggered by a small pressing force.

[0049] Combine the following Figure 1-Figure 5 As shown, in one embodiment of the present invention, each main wave rod 120 is in a long strip structure, and the two ends of each main wave rod 120 respectively form a force-bearing end 120a and a connecting end 120b. Figure 4As shown. In addition, a rotating shaft 121 is protruded from the middle of each main wave lever 120, and the axial direction of the rotating shaft 121 is perpendicular to the length direction of the main wave lever 120. When installed on the base 110, the rotating shaft 121 of the main wave lever 120 is pivotally connected to the base 110, and its connecting end 120b is pivotally connected to the auxiliary wave lever 130, and its force-bearing end 120a protrudes upward from the top of the base 110, as shown in FIG. Figure 1 As shown. Combined Figure 11-14 As shown, when the force-bearing end 120a of the main wave lever 120 is subjected to downward pressure, the main wave lever 120 will rotate with its rotating shaft 121 as a fulcrum, so that its force-bearing end 120a moves toward the base 110, and its connecting end 120b moves upward from the base 110, thereby driving the auxiliary wave lever 130 to move upward from the base 110, so that the auxiliary wave lever 130 triggers the touch pad 200, so that when the corner of the touch pad 200 is subjected to force, it can also ensure that the touch pad 200 is triggered quickly, and only a small pressing force is required to achieve the triggering.

[0050] See Combination Figure 4-Figure 5 , Figure 9-14 As shown, in the present embodiment, the force-bearing end 120a of each main wave lever 120 preferably has an arc-shaped structure, specifically, it is bent upward compared to the axis in the length direction of the main wave lever 120, so that the force-bearing end 120a protrudes upward after being bent, that is, the force-bearing end 120a is bent upward compared to the axis in the length direction of the main wave lever 120, so that after the main wave lever 120 is pivotally connected to the base 110, the force-bearing end 120a protrudes above the base 110. More preferably, the force-bearing end 120a is also provided with a protruding portion 122, and the protruding direction of the protruding portion 122 is the same as the protruding direction of the force-bearing end 120a. When the main wave lever 120 is installed, the force-bearing end 120a and the protruding portion 122 thereon both protrude above the base 110, as shown in FIG. Figure 1 , Fig. 9 In this way, when a small force is applied to the corner or edge of the touch panel 200, it can act on the protrusion 122, thereby driving the main wave lever 120 to pivot, so that the connecting end 120b of the main wave lever 120 moves upward and pushes the auxiliary wave lever 130 to move upward, so that the auxiliary wave lever 130 abuts against the touch panel 200 to achieve triggering, and only a small pressing force value and pressing stroke are required to achieve contact triggering with the touch panel 200.

[0051] See also Figure 4As shown, in this embodiment, the connection end 120b of each main wave lever 120 is provided with at least one connection shaft 123, and the axial direction of the connection shaft 123 is the same as the axial direction of the rotating shaft 121 of the main wave lever 120, and the connection shaft 123 is pivoted to the auxiliary wave lever 130, so that the pivot connection between the main wave lever 120 and the auxiliary wave lever 130 is simple. In a specific embodiment, the connection end 120b of each main wave lever 120 is provided with two connection shafts 123, and the two connection shafts 123 are arranged along the same straight line and are spaced apart from each other. Specifically, the centers of the two connection shafts 123 are located on the same straight line, and the outer diameters of the two connection shafts 123 are preferably the same. By pivoting with the auxiliary wave lever 130 through the two spaced connection shafts 123, the connection between the two is more stable, and the force of the auxiliary wave lever 130 is more balanced.

[0052] Continue to view Figure 4 As shown, more specifically, two through holes 124 are formed through the connecting end 120b, and the two through holes 124 are spaced apart from each other. The portion between each through hole 124 and the end of the connecting end 120b forms the connecting shaft 123, and the connecting shaft 123 preferably has an arc-shaped structure to make the pivot connection between the connecting shaft 123 and the auxiliary wave lever 130 smoother.

[0053] It can be understood that only one connecting shaft 123 is set at the connecting end 120b, and the length of the connecting shaft 123 corresponds to the length of one side of the auxiliary wave rod 130. The auxiliary wave rod 130 is pivotally connected to the connecting shaft 123, which can also make the pivot connection between the two stable and the auxiliary wave rod 130 balanced in force.

[0054] Continue to combine Figure 4-5 As shown, in this embodiment, each main wave rod 120 is further provided with a reinforcing rib 125, which extends along the length direction of the main wave rod 120, and the reinforcing rib 125 protrudes upward perpendicularly to the body of the main wave rod 120, that is, the protruding direction of the reinforcing rib 125 is the same as the protruding direction of the protruding portion 122, and the reinforcing rib 125 and the protruding portion 122 are located on the same side of the main wave rod 120. The reinforcing rib 125 is provided to strengthen the rigidity of the main wave rod 120, so as to ensure that the main wave rod 120 is not easily deformed during the force application process.

[0055] Combine the following Figure 1-Figure 4As shown, in one embodiment of the present invention, the base 110 is provided with mounting holes 111 corresponding to each main wave lever 120. Specifically, the outer diameter of each mounting hole 111 is larger than the outer diameter of the main wave lever 120. And a mounting groove 111a is provided on the side wall of each mounting hole 111. Each main wave lever 120 is correspondingly accommodated in a mounting hole 111, and a rotating shaft 121 disposed in the middle thereof is pivotally connected to the mounting groove 111a. At the same time, the force-bearing end 120a of the main wave lever 120 protrudes above the base 110. Combined with Figure 11-14 As shown, when the force-bearing end 120a is subjected to force, the main wave lever 120 is driven to rotate with its rotating shaft 121 as a fulcrum, so that its connecting end 120b moves upward to the base 110, thereby driving the auxiliary wave lever 130 to move upward to the base 110.

[0056] More preferably, the base 110 is further provided with a connecting seat 112, which is arranged between each mounting hole 111. Moreover, each mounting hole 111 is preferably evenly arranged around the connecting seat 112. The connecting seat 112 supports the auxiliary wave lever 130, so that the installation and up-and-down movement of the auxiliary wave lever 130 are more stable. At the same time, the edge position of the auxiliary wave lever 130 is pivotally connected to each main wave lever 120. Therefore, when the auxiliary wave lever 130 is pushed by the main wave lever 120, the auxiliary wave lever 130 moves upward compared to the connecting seat 112, so that the movement of the auxiliary wave lever 130 is more stable, so that it can contact the touch panel 200 more stably and achieve stable triggering.

[0057] Combine the following Figure 1-Figure 8 As shown, in a specific embodiment of the present invention, the touchpad key module 100 includes two main wave levers 120. Accordingly, two mounting holes 111 are provided on the base 110, each mounting hole 111 is a rectangular structure, and the two mounting holes 111 extend in the same direction and a connecting seat 112 is provided between the two. In this specific embodiment, the connecting seat 112 is a rod-shaped structure and the axial direction of the connecting seat 112 is consistent with the axial direction of the rotating shaft 121 of the main wave lever 120. Each main wave lever 120 is pivoted in one mounting hole 111. During installation, the auxiliary wave lever 130 is supported above the connecting seat 112, and the two opposite ends of the auxiliary wave lever 130 are pivoted to the connecting shafts 123 of the two main wave levers 120. Therefore, when any force is applied to the force-bearing end 120 a of any main wave lever 120 , the main wave lever 120 pivots to move its connecting end 120 b upwards toward the base 110 , thereby driving the auxiliary wave lever 130 to move upwards toward the connecting seat 112 .

[0058] It is understandable that the touchpad key module 100 is not limited to having only two main wave levers 120. Of course, more main wave levers 120 can be provided, and in this case, each main wave lever 120 can be arranged at intervals around the connecting seat 112. Correspondingly, the connecting seat 112 can be set to a spherical, hemispherical or other arc-shaped structure. The secondary wave lever 130 is supported on the connecting seat 112, and the secondary wave lever 130 is respectively pivoted to each main wave lever 120, and the secondary wave lever 130 can also be driven by each main wave lever 120 to move upward. This structural setting can enable the touchpad 200 to be quickly triggered when any edge position or corner position is pressed.

[0059] Combine the following Figure 3-4 , Figure 6 As shown, in one embodiment of the present invention, the secondary wave lever 130 includes a connecting plate 131 and a clamping jaw 133 protruding from a side of the connecting plate 131, and a first clamping groove 132 is formed between each pair of clamping jaws 133. Therefore, the number of pairs of clamping jaws 133 corresponds to the number of connecting shafts 123 of the main wave lever 120. Each first clamping groove 132 is engaged with the outside of a connecting shaft 123 of the main wave lever 120 to achieve pivotal connection, thereby making the pivotal connection between the main wave lever 120 and the secondary wave lever 130 simple. When the connecting end 120b of the main wave lever 120 moves upward to push the secondary wave lever 130, the secondary wave lever 130 pivots and moves to the top of the base 110 so that its connecting plate 131 contacts the touch panel 200, thereby achieving rapid triggering.

[0060] See also Figure 6 As shown, in this embodiment, the opposite surfaces of each pair of clamping jaws 133 are provided with first clamping surfaces 1331 in an arc-shaped structure, and the first clamping groove 132 is formed between the two first clamping surfaces 1331, and the outer diameter of the first clamping groove 132 is slightly larger than the outer diameter of the connecting shaft 123. In addition, the ends of each pair of clamping jaws 133 are spaced apart to form a clamping entrance 134 communicating with the first clamping groove 132. When connected with the main wave lever 120, the connecting shaft 123 is clamped into the first clamping groove 132 through the clamping entrance 134, so that the connecting shaft 123 can be pivotally connected to the first clamping groove 132, so that the connection between the main wave lever 120 and the auxiliary wave lever 130 is simple.

[0061] Continue to view Figure 6As shown, in a specific embodiment, corresponding to each main wave rod 120, two pairs of jaws 133 are provided to be pivotally connected thereto. Therefore, a total of four pairs of jaws 133 are provided on the connecting plate 131. Specifically, two pairs of jaws 133 are provided at each end of the connecting plate 131 in the lateral direction (X direction). Moreover, at one end of the connecting plate 131 in the lateral direction, two pairs of jaws 133 are provided on the connecting plate 131 at intervals and are provided in the longitudinal direction (Y direction) of the connecting plate 131. The spacing between the two pairs of jaws 133 corresponds to the two connecting shafts 123 of the main wave rod 120, and the first slots 132 of the two pairs of jaws 133 are located on the same axis. The two pairs of jaws 133 provided at the other end of the connecting plate 131 in the lateral direction (X direction) have the same structure. Combined with Figure 2 As shown, during installation, the two connecting shafts 123 of a main wave lever 120 are respectively pressed into the first clamping grooves 132 between the two pairs of clamping jaws 133 to achieve pivot connection, which not only makes the connection between the two simple and stable, but also makes the force between the two more balanced.

[0062] Continue to combine Figure 1-Figure 6 As shown, in this embodiment, a second clamping groove 135 is further provided in the middle of the secondary wave lever 130, and the outer diameter of the second clamping groove 135 is larger than the outer diameter of the above-mentioned connecting seat 112. The secondary wave lever 130 is clamped on the connecting seat 112 through the second clamping groove 135 to support the secondary wave lever 130. When the main wave lever 120 pivots and applies force to the secondary wave lever 130, the secondary wave lever 130 can be pushed to move upward compared to the connecting seat 112.

[0063] Combination Figure 2 , Figure 6 As shown, the second clamping groove 135 is formed between the clamping jaws 133 provided at both ends of the connecting plate 131 in the horizontal direction (X direction). Specifically, a second clamping surface 1332 is formed in an arc shape on a side of the middle clamping jaw 133 away from the first clamping surface 1331, and the concave direction of the second clamping surface 1332 is opposite to the concave direction of the first clamping surface 1331. The second clamping groove 135 is formed between the second clamping surfaces 1332 on the middle clamping jaw 133. The second clamping groove 135 is clamped to the outside of the connecting seat 112 with a rod-shaped structure to support the auxiliary wave rod 130 without affecting the up and down movement of the auxiliary wave rod 130. This structural setting of simultaneously forming the first clamping groove 132 and the second clamping groove 135 by using the clamping jaws 133 at both ends of the connecting plate 131 simplifies the structure of the auxiliary wave rod 130. It can be understood that it is also feasible to form the second clamping groove 135 by providing other clamping jaws on the connecting plate 131.

[0064] Combination Figure 3 , Figure 7-8As shown, in this embodiment, a trigger portion 131a is also convexly provided on a side of the connecting plate 131 away from the clamping claw 133, that is, the trigger portion 131a is convexly provided on the top surface of the connecting plate 131, and the trigger portion 131a is preferably in a cross shape. When the auxiliary wave lever 130 is subjected to a small thrust force, the trigger portion 131a above it can act on the touch panel 200, and the trigger portion 131a in a cross shape can increase its contact position with the touch panel 200, thereby making the trigger more sensitive, improving the electrical connectivity and the pressing feel.

[0065] Combine the following Figure 1-Figure 17 As shown, in one embodiment of the present invention, a touch panel module 1 is also provided, which includes a touch panel 200 and the touch panel key module 100 as described above. Figure 16-17 As shown, a trigger button 210 is convexly disposed on the touch panel 200. The touch panel button module 100 is disposed below the touch panel 200, and the trigger portion 131a on the auxiliary wave lever 130 is in contact with the trigger button 210 in a corresponding manner up and down.

[0066] Combination Figure 15-17 As shown, in this embodiment, the touch panel module 1 further includes a housing 300, a membrane assembly 400 and a glass cover 500. The housing 300 is disposed above the touch panel key module 100, and both ends of the housing 300 are in contact with the protrusions 122 of the two main wave rods 120. Fig.16 As shown. The diaphragm assembly 400 is disposed above the housing 300, the touch panel 200 is disposed above the diaphragm assembly 400, and the glass cover plate 500 is covered above the touch panel 200. Among them, through holes are opened at positions corresponding to the auxiliary wave lever 130 on the housing 300 and the diaphragm assembly 400, so that the triggering part 131a of the auxiliary wave lever 130 can contact the triggering button 210 of the touch panel 200. In this application, the structures and settings of the housing 300, the diaphragm assembly 400, and the glass cover plate 500 are all conventional methods in the art and will not be described in detail.

[0067] Combine the following Fig.15 , Figure 18-24 As shown, the touch panel module 1 of the present invention is simulated and analyzed. In the present invention, the base 110, the main wave lever 120, and the auxiliary wave lever 130 are preferably all plastic structures, for example, they are all formed by ABS plastic and / or PC (Polycarbonate) material, and of course other plastic materials can also be used to form them, so as to make the overall cost of the touch panel module 1 lower.

[0068] A simulation condition adopted by the present invention is as follows Fig.18As shown: the border area 210 above the touch panel 200 is fixed, and the diameter of the pressure head used is 7.5mm. When pressing, the distance from the edge of the touch panel 200 is 5mm, and a forced displacement of 0.5mm is applied (in most projects, the trigger displacement of the touch panel 200 is about 0.5mm). Fig.18 Perform simulation pressing test on point 1 and point 2 in the test.

[0069] Combine first Figure 19-21 As shown, when simulating point 1, the trigger force is 237g and the trigger displacement is 0.3mm. In general electronic devices, the trigger force standard is usually 150-250g, and the trigger displacement standard is usually less than 0.9mm. Therefore, under the condition of a trigger force of 237g, the trigger displacement of the touchpad module 1 in this application is much less than 0.9mm, so it meets the requirements. Secondly, the stress at the shaft 121 of the base 110 is the largest, which is 3.82Mpa. Fig.19 As shown in the figure, the yield strength of PC+ABS is 44.58Mpa, and the stress at the shaft 121 is lower than the material yield strength of 44.58Mpa, so the failure risk is low. The stress at the shaft 121 of the main wave levers 120 on the left and right sides is the largest, which are 5.74Mpa and 5.11Mpa respectively. Figure 20-21 As shown, they are all lower than the material yield strength of 44.58Mpa, and the failure risk is low.

[0070] Combine the following Figure 22-24 As shown, when simulating point 2, the trigger force is 184g and the trigger displacement is 0.09mm, which is much smaller than 0.9mm and thus meets the requirements. Secondly, the stress at the rotating shaft 121 of the base 110 is the largest, which is 0.93Mpa. Fig. 22 As shown, the stress at the rotating shaft 121 of the main wave lever 120 on the left and right sides is the largest, which is 1.91Mpa and 2.23Mpa respectively. Figure 23-24 As shown, it is lower than the material yield strength of 44.58Mpa and the risk of failure is low.

[0071] Combine the following Figure 9-14 , Figure 16-17 As shown, when the touch panel module 1 of the present invention is in use, if the left key corner of the touch panel 200 is pressed, the force end 120a of the left main wave lever 120 will be forced to move downward, as shown in FIG. Fig.11 As shown by the middle arrow F, the main wave lever 120 rotates around its rotating shaft 121 to drive the connecting end 120b at its right end to move upward, and then the connecting end 120b drives the auxiliary wave lever 130 to move upward, so that the triggering part 131a of the auxiliary wave lever 130 triggers the trigger button 210 just above, as shown in FIG. Figure 16-17 shown.

[0072] When the right corner of the touch panel 200 is pressed, the force-bearing end 120a of the right main swing lever 120 moves downward. Fig.13 As shown by the middle arrow F, the main wave lever 120 rotates around its rotation axis 121 to drive the connecting end 120b at its left end to move upward, and then the connecting end 120b drives the auxiliary wave lever 130 to move upward, triggering the trigger button 210 just above the auxiliary wave lever 130, as shown in FIG. Figure 16-17 shown.

[0073] When the middle of the touch panel 200 is pressed, the touch panel 200 drives the trigger button 210 thereon to move downward, directly interacting with the auxiliary wave lever 130, such as Fig. 9 At this time, the force-bearing ends 120a of the main wave levers 120 on both sides are in contact with the touch panel 200 in the vertical direction and cannot move up and down, so the trigger button 210 can be triggered smoothly. Figure 9-10 shown.

[0074] Combination Figure 9-14 As shown, when the main wave lever 120 is pressed to the position above the rotation axis 121, the main wave lever 120 will not pivot around the rotation axis 121, so that the positions of the main wave lever 120 and the auxiliary wave lever 130 remain unchanged. Therefore, the touch panel 200 itself is deformed to drive the trigger button 210 below it to move downward and contact the trigger portion 131a on the auxiliary wave lever 130, thereby achieving triggering.

[0075] In summary, the touchpad key module 100 of the present invention pivotally connects at least two main wave levers 120 on the base 110, so that each main wave lever 120 forms a lever, and a secondary wave lever 130 is arranged between each main wave lever 120, and the secondary wave lever 130 is pivotally connected to one end of each main wave lever 120, so that when the end of each main wave lever 120 away from the secondary wave lever 130 is subjected to force, the main wave lever 120 pivots relative to the base 110 and drives the secondary wave lever 130 to move upward relative to the base 110, so that the secondary wave lever 130 contacts the touchpad 200 to achieve triggering. In this way, even if the touchpad 200 is deformed or pressed to the corner, edge, etc. of the touchpad 200, the touchpad 200 can be quickly triggered, which solves the problem of invalid triggering caused by deformation of the touchpad 200 and other reasons in the prior art. Secondly, the lever formed by the main wave lever 120 is used to compensate for the pressing stroke, which can not only effectively compensate for the problem of too long pressing stroke caused by deformation of the touch panel 200, but also ensure that the edge or corner of the touch panel 200 can be triggered when pressed, and only a small pressing force is required to trigger, making the trigger more sensitive and increasing the pressing feel. Furthermore, by flexibly setting the fulcrum position between the main wave lever 120 and the base 110, different pressing force values ​​and pressing stroke requirements can be met, thereby effectively controlling the pressing stroke of the corner position of the key. In addition, the main wave lever 120 and the auxiliary wave lever 130 have a simple structure and can be made of all plastic, thereby reducing production costs and thus reducing overall costs.

[0076] Correspondingly, the touch panel module 1 having the touch panel key module 100 of the present invention also has the above technical effects.

[0077] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
