When the first region is pressed in a first direction, the touchpad remains stationary. When the second region is pressed in the first direction, the second region moves along the first direction. By configuring the touchpad with a first region and a second region, this disclosure ensures the normal operation of the touchpad module during normal operation. When the first region is accidentally touched, the touchpad cannot be pressed down, preventing the switch from being triggered and producing a clicking sound.

Description

Technical Field

[0001] This disclosure relates to the field of electronic device technology, and more specifically, to a touchpad module and an electronic device. Background Technology

[0002] Laptops, as portable electronic devices, are beloved by users, providing a convenient and efficient work and entertainment experience. In the pursuit of portability, laptops have gradually become increasingly thin and light, which places higher demands on the optimization and improvement of various parts of the product's structure. The touchpad is a key moving component in a laptop, and its structural design has a significant impact on the user experience.

[0003] For laptops, such as Figure 1 As shown, the touchpad module 400' is generally located below the button module 300'. In order to meet the user experience, the size of the touchpad module 400' is getting larger and larger, and the current maximum size has reached 150 mm × 98 mm. The excessive size makes it easy for the mechanical switch touchpad to press the touch area when the palm is pressed when operating the keyboard, which will cause the switch 410' to be pressed and thus the switch 410' to be triggered. Even if the function can be locked by software, the mechanical switch 410' will still produce a clicking sound when it is pressed. Summary of the Invention

[0004] In view of the above, according to one aspect of this disclosure, a touchpad module is provided, the technical solution of which is as follows.

[0005] A touchpad module, comprising a touchpad;

[0006] The touchpad has a first area and a second area;

[0007] Specifically, when the first area is subjected to pressure in the first direction, the touchpad remains stationary; when the second area is subjected to pressure in the first direction, the second area can move along the first direction.

[0008] In one possible implementation, when the second region is subjected to pressure in a first direction, the first region can move in a second direction opposite to the first direction.

[0009] In one embodiment, the system further includes a rotation axis, which allows the second region to rotate about the rotation axis in the first direction when the second region is subjected to pressure in the first direction.

[0010] In one embodiment, the touchpad has a first side and a second side opposite to each other, and the rotation axis is at a distance L1 between the first side and the second side, and at a distance L2 between the rotation axis and the second side, where L2:L1 = 1 to 2.

[0011] In one embodiment, a first base plate is further included, which supports the first region. When a pressing force in a first direction is applied to the first region, the first base plate restricts the displacement of the touch panel to keep the touch panel stationary.

[0012] In one embodiment, a second base plate is further included, which supports the second region of the portion. The second base plate is hinged to the first base plate and forms the rotation axis at the hinge position. When a pressing force in a first direction is applied to the second region, the second base plate can rotate along the first direction around the rotation axis with the touch panel.

[0013] In one embodiment, it further includes an elastic element for rotating the second base plate relative to the first base plate when the second region is subjected to pressure in the first direction, and for driving the second base plate and the touch panel to reset after the pressure is removed.

[0014] In one embodiment, the elastic element includes a first frame and a second frame. The first frame is disposed on the second base plate, and the second frame is disposed near the second side. The second region has a pressing area disposed near the second side. When the pressing area is subjected to pressing pressure in a first direction, the second frame can move along the first direction to drive the first frame to rotate the second base plate relative to the first base plate.

[0015] In one embodiment, the system further includes a pressure-bearing bracket and a balance bar. The pressure-bearing bracket is supported below the pressing area and opposite to the second frame. The balance bar is supported between the pressure-bearing bracket and the second frame and is rotatable about a set fulcrum on the second frame.

[0016] According to another aspect of this disclosure, an electronic device is also provided, including a system terminal having an operating surface having a functional component arrangement direction, and a keyboard and touchpad module being disposed on the operating surface along the functional component arrangement direction; the touchpad module includes a touchpad; the touchpad has a first region and a second region, wherein, in the functional component arrangement direction, the first region is closer to the keyboard than the second region; wherein, when a pressing force is applied to the first region toward the operating surface, the touchpad can remain stationary; and when a pressing force is applied to the second region toward the operating surface, the second region can move along the direction of the pressing force.

[0017] This disclosure has the following beneficial effects: by setting the touchpad into a first area and a second area, the touchpad can remain stationary when the first area is pressed in the first direction; when the second area is pressed in the first direction, the second area can move along the first direction; thus, during normal operation, the second area can be pressed down to ensure the normal use of the touchpad module. When the first area is accidentally touched, the touchpad cannot be pressed down, which can prevent the switch from being triggered and producing a clicking sound.

[0035] In the following description, numerous details are provided to enable a thorough understanding of this disclosure. However, those skilled in the art will appreciate that the following description merely illustrates alternative embodiments of this disclosure by way of example, and that this disclosure can be implemented without one or more of these details. Furthermore, to avoid confusion with this disclosure, some technical features well-known in the art have not been described in detail.

[0036] The touchpad module disclosed herein is primarily used in electronic devices to control cursor movement by sensing the movement of a user's finger. These electronic devices can be servers, laptops, televisions, etc., and are not listed here. However, it is understood that the electronic devices in this disclosure are not limited to the specific electronic devices mentioned above. For the overall understanding of this disclosure, a laptop computer will be used as an example to describe the touchpad module below.

[0037] like Figure 2As shown, the laptop computer includes a display terminal 100 and a system terminal 200, which are rotatably connected. The display terminal 100 includes a screen that converts the video signal output from the system terminal 200 into an image. The system terminal 200 has an operation surface 201 with a functional component arrangement direction A. A keyboard 300 and a touchpad module 400 are arranged on the operation surface 201 along the functional component arrangement direction A. The touchpad module 400 and the keyboard 300 are arranged in a front-to-back configuration along the functional component arrangement direction A. It should be noted that when a user operates the laptop computer, the side of the system terminal 200 closer to the user is called the "front," and the side of the system terminal 200 further away from the user is called the "rear." The touchpad module 400 is mainly designed to improve the portability of the laptop computer, allowing it to replace the mouse for control, or to work in conjunction with the mouse to further enhance portability. The touchpad module 400 will be described in detail below.

[0038] See also Figures 3 to 12 The touchpad module 400 includes a touchpad 10, which has a first area and a second area (as shown in the figure). Figure 3 In general, the first area is the area where the first base plate 21 is located, and the second area is the area of ​​the touchpad 10 excluding the first area. When the first area is pressed in the first direction B, the touchpad 10 remains stationary; when the second area is pressed in the first direction B, the second area can move along the first direction B. A switch 90 is provided in the second area. Specifically, the touchpad 10 mainly includes a touch panel 11 and a circuit board 12. The touch panel 11 and the circuit board 12 are glued together, meaning that the touch panel 11 and the circuit board 12 are fixedly connected as a single unit to form the touchpad 10. The switch 90 can be disposed on the circuit board 12, such as attached to the surface of the circuit board 12. The touch panel 11 has a pressing area 101, and the switch 90 is disposed corresponding to the pressing area 101. When a pressing force of the first direction B is applied to the pressing area 101 to perform normal operation of the touchpad module 400, the switch 90 can be triggered, producing a click sound. (See also...) Figure 2 When the touchpad module 400 is applied to an electronic device, in the functional component arrangement direction A, the first area is closer to the keyboard 300 than the second area. Based on the above structure, when the touchpad module 400 applies pressure to the second area towards the operation surface 201 (the direction of the pressure is shown by arrow B in Figure 5, i.e., the first direction mentioned above) to perform normal operation, the second area can be pressed down to trigger the switch 90, ensuring the normal use of the touchpad module 400. When operating the keyboard 300 towards the operation surface 201 and accidentally touching the first area with the palm, the touchpad 10 cannot be pressed down, thus preventing the switch 90 from being triggered and producing a clicking sound.

[0039] In one specific embodiment of this disclosure, when the second region is subjected to pressure in the first direction B, the first region can move in the second direction opposite to the first direction B. In this way, the touchpad 10 is approximately a seesaw. During normal operation of the touchpad 10, the touchpad 10 moves as a whole, which can prevent the touchpad 10 from bending and deforming and affecting its service life.

[0040] To improve the user experience when operating the touchpad 10, in one specific embodiment of this disclosure, the touchpad module further includes a rotation axis. When the second region is pressed in the first direction B, the second region can rotate around the rotation axis in the first direction B. As shown in Figures 5 and 6, the touchpad 10 has a touch surface 102 and a back surface 105 arranged opposite to each other. The touch surface 102 is the side of the touchpad 10 facing the operator, and the back surface 105 is the side of the touchpad 10 facing away from the operator. After the touchpad module 400 is assembled on the C-side shell of the laptop, the back surface 105 is not visible. In an embodiment not shown, a hinge portion can be provided on the back surface 105 of the touchpad 10 to hinge the touchpad 10 to the C-side shell of the laptop. The center of the hinge portion is the rotation axis.

[0041] like Figure 4 As shown, in a specific embodiment of this disclosure, in order to further ensure that the touchpad 10 cannot be pressed down when the first area is accidentally touched, the touchpad 10 has a first side 103 and a second side 104 opposite to each other. Figure 2 In the case of the laptop shown, in the functional component arrangement direction A, the first side 103 is the side of the touchpad 10 closest to the keyboard 300, and the second side 104 is the side of the touchpad 10 furthest from the keyboard 300, with the rotation axis ( Figure 7 In the illustrated embodiment, the rotation axis (i.e., the central axis of the rotating shaft 212) has a distance L1 between it and the first side 103, and a distance L2 between it and the second side 104, where L2:L1 = 1 to 2. Thus, compared to the prior art where the rotation axis of the touchpad module 400 is located closer to the keyboard 300, it is moved forward to approximately 2 / 3 or 1 / 2 of the position of the touchpad 10 in the functional component arrangement direction A, further preventing the switch 90 from being accidentally triggered when the first area is subjected to pressure in the first direction B. Furthermore, in the functional component arrangement direction A, the touchpad 10 can be divided into a first area and a second area by the rotation axis, so that when the touchpad module 400 is normally pressed, the second area descends and the first area rises.

[0042] In one specific embodiment of this disclosure, in order to ensure that the touchpad 10 remains stationary when the first region is subjected to a pressing force in the first direction B, the touchpad module 400 further includes a first base plate 21. The first base plate 21 is used to support the first region. When a pressing force in the first direction B is applied to the first region, the first base plate 21 restricts the displacement of the touchpad 10 so that the touchpad 10 remains stationary.

[0043] Furthermore, in order to better enable the second region to move along the first direction B when it is pressed by the first direction B, the touchpad module 400 also includes a second base plate 22. The area of ​​the second base plate 22 is smaller than the area of ​​the second region. The second base plate 22 is used to support the second region. The second base plate 22 is hinged to the first base plate 21 and forms a rotation axis at the hinge position. In this way, when the first direction B is applied to the second region, the second base plate 22 can rotate along the first direction B around the rotation axis with the touchpad 10.

[0044] Specifically, such as Figure 3 and Figure 7 As shown, the first base plate 21 is fixedly installed. For a laptop computer, the first base plate 21 can be fixed to the C-side shell of the laptop computer by fasteners such as screws. The touchpad 10 is connected to the first base plate 21 through a limiting block 80. The connection method between the limiting block 80, the touchpad 10, and the first base plate 21 is as follows: the first base plate 21 has a connecting hole 211, the limiting block 80 is limited within the connecting hole 211 and is limited to be able to move along the connecting hole 211, and the touchpad 10 is fixedly connected to the limiting block 80. In this way, based on the setting of the first base plate 21, when the first area is pressed by the first direction B, the touchpad 10 can remain stationary; when the second area is pressed by the first direction B, the touchpad 10 is approximately a seesaw, the second area moves along the first direction, and the first area is guided by the connecting hole 211 and the limiting block 80 to move together with the second area and moves in a second direction opposite to the first direction B with the rotation axis as the fulcrum.

[0045] like Figure 7 As shown, in order to facilitate the hinged connection of the first base plate 21 and the second base plate 22, a rotating shaft 212 can be provided on the first base plate 21 and a mounting hole 222 can be provided on the second base plate 22. The end of the rotating shaft 212 passes through the mounting hole 222. Alternatively, a rotating shaft can be provided on the second base plate 22 and a mounting hole can be provided on the first base plate 21. The end of the rotating shaft passes through the mounting hole, which can also achieve the purpose of hinged connection of the first base plate 21 and the second base plate 22.

[0046] To enable the touchpad 10 to reset after movement, the touchpad module 400 also includes an elastic element 30. The elastic element 30 is used to rotate relative to the first base plate 21 with the second base plate 22 when the second area is subjected to pressure in the first direction B, and to drive the second base plate 22 and the touchpad 10 to reset after the pressure is released. Again, taking a laptop computer as an example, the first base plate 21 is fixedly mounted on the C-side shell of the laptop computer, the second base plate 22 is hinged to the first base plate 21, and the elastic element 30 is connected to the second base plate 22.

[0047] It should be understood that in order to achieve the following: when the first area is pressed by the first direction B, the touch panel 10 can remain stationary, and when the second area is pressed by the first direction B, the second area can move along the first direction B. In addition to the first base plate 21 and the second base plate 22 that are hinged together as described above, the touch panel 10 can also use an elastic base plate. The elastic base plate is divided into a first area and a second area. The first area can achieve the above effect by setting a fixed back plate to limit the elasticity.

[0048] See also Figure 3 , Figure 7 and Figure 8 In one embodiment of this disclosure, the elastic element 30 is a frame structure, including a first frame 31 and a second frame 32. The first frame 31 is fixedly mounted on the second base plate 22 by fasteners such as screws. The second frame 32 is disposed near the second side 104. The pressing area 101 is located in the second region and disposed near the second side 104. The second frame 32 is opposite to the pressing area 101. The first frame 31 and the second frame 32 are connected by a connecting frame 33, which can be multiple strips to ensure the resilience of the elastic element 30. Based on this structural configuration, the second frame 32 can move along the first direction B when the pressing area 101 is subjected to a pressing force in the first direction B, thereby driving the first frame 31 to rotate the second base plate 22 relative to the first base plate 21. It should be understood that the elastic element 30 is not limited to the frame structure. As long as it is elastic, can move along the first direction B when the pressing area 101 is subjected to the pressing pressure in the first direction B, thereby driving the first frame 31 to rotate the second base plate 22 relative to the first base plate 21, and drive the second base plate 22 and the touch panel 10 to reset after the pressing pressure is removed.

[0049] See also Figure 7 , Figure 8 and Figure 9The touchpad module 400 also includes a pressure-bearing bracket 40 and a balance bar 50. The pressure-bearing bracket 40 is supported below the pressing area 101 and opposite to the second frame 32. The pressure-bearing bracket 40 may be fixedly mounted on the back surface 105 and corresponding to the pressing area 101. The balance bar 50 is supported between the pressure-bearing bracket 40 and the second frame 32, and the balance bar 50 can rotate around a set fulcrum on the second frame 32. The balance bar 50 can transmit the torque when pressed on one side (i.e., when one end of the balance bar 50 is pressed, the entire balance bar 50 rotates slightly), so that when the touchpad 10 is operated normally, the entire touchpad 10 can move downward synchronously, thereby improving the user experience. To facilitate the installation of the balance bar 50, the second frame 32 has a remote side 321 away from the second side 104. A bent body 322 is formed on the remote side 321 towards the touch panel 10. Both ends of the bent body 322 have locking holes 3221. The two ends of the balance bar 50 are bent to form support rod portions 51, which pass through the locking holes 3221, thus forming the aforementioned setting fulcrum at the location of the locking holes 3221. To limit the position of the balance bar 50, the pressure-bearing bracket 40 has a pressure-bearing back side 41 facing away from the touch panel 10. The pressure-bearing back side 41 is provided with a locking groove 412 for locking the balance bar 50.

[0050] See also Figure 10 , Figure 11 and Figure 12 The pressure-bearing bracket 40 also has an elastic frame portion 42, which is provided with a mounting groove 422 and a pressure-bearing column 421. The pressure-bearing column 421 corresponds to the switch 90 provided on the circuit board 12. Under normal conditions, the pressure-bearing column 421 does not contact the switch 90. In order to facilitate the operation of the switch 90, a pressure-applying rod portion 52 extends from the middle of the balance bar 50. The pressure-applying rod portion 52 is engaged in the mounting groove 422, and the pressure-applying rod portion 52 can make the switch 90 contact the pressure-bearing column 421 when the touch panel module 400 is operated normally.

[0051] See also Figure 2 , Figure 3 , Figure 7 , Figure 9 , Figure 10 , Figure 11 and Figure 12 When a pressing force is applied to the pressing area 101 of the touch panel 11 toward the operating surface 201, that is, during normal operation of the touch panel module 400, since the touch panel 10 is fixedly connected to the pressure support 40 and the second base plate 22, and the second base plate 22 is hinged to the first base plate 21, the touch panel 10 rotates around the central axis of the rotating shaft 212. At the same time, the balance bar 50 moves with the movement of the touch panel 10, so that the switch 90 contacts the pressure column 421, thereby triggering the switch 90. When the pressing force is released, the touch panel 10 is reset under the action of the elastic element 30.

[0052] See again Figure 3 and Figure 7 In one embodiment of this disclosure, a third base plate 60 is further provided on the back surface 105 in the area between the pressure-bearing bracket 40 and the second base plate 22. The third base plate 60 is used to enhance the support strength of the touch panel 10, and the size of the third base plate 60 can be determined according to the size of the touch panel 10.

[0053] As described above, the electronic device according to this disclosure includes a display terminal 100 and a system terminal 200. The display terminal 100 and the system terminal 200 are rotatably connected. The system terminal 200 has an operation surface 201 with a functional component arrangement direction A. A keyboard 300 and a touchpad module 400 are arranged on the operation surface 201 along the functional component arrangement direction A. The touchpad module 400 adopts the structure described above. Apart from this, the display terminal 100 and the like may have various existing or future possible structures, which do not constitute a limitation on the scope of protection of this disclosure.

[0054] The electronic device (in this disclosure, a laptop computer is used as an example) is based on the touchpad module 400. Since the first area can effectively support pressure, even if the palm presses on the first area of ​​the touchpad 10 when operating the keyboard 300, the switch 90 can be prevented from being triggered and producing a clicking sound.

[0055] In the description of this disclosure, it should be understood that the orientation or positional relationship indicated by directional terms is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this disclosure and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this disclosure; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0056] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," and "above" are used herein to describe the spatial positional relationship between one or more components or features shown in the figures and other components or features. It should be understood that spatial relative terms include not only the orientation of the component as depicted in the figures but also different orientations during use or operation. For example, if the components in the figures are inverted as a whole, "above" or "above other components or features" will include cases where the component is "below" or "under" other components or features. Thus, the exemplary term "above" can include both "above" and "below." Furthermore, these components or features may also be positioned at other different angles (e.g., rotated 90 degrees or other angles), and this document intends to include all such cases.

[0057] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, parts, components, and / or combinations thereof.

[0058] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in sequences other than those illustrated or described herein.

[0059] This disclosure has been described through the above embodiments; however, it should be understood that the above embodiments are for illustrative purposes only and are not intended to limit this disclosure to the described embodiments. Furthermore, those skilled in the art will understand that this disclosure is not limited to the above embodiments, and many more variations and modifications can be made based on the teachings of this disclosure, all of which fall within the scope of protection claimed by this disclosure. The scope of protection of this disclosure is defined by the appended claims and their equivalents.
