Description

Technical Field

[0001] This invention relates to the field of touchpad technology, and more particularly to a touchpad bracket, a touchpad, and an electronic input device. Background Technology

[0002] Currently, there are many types of input devices used to perform input operations in electronic devices. During operation, users move a cursor and select on a display screen. For example, laptops typically have touchpads with a touch module, which users click and press when using. Because the touch module is located in the center of the circuit board, and touchpads are usually rectangular, pressing the edge of the touchpad may not cause the touch module to compress or collapse. Therefore, a device is needed that can trigger the touch module even when the edge of the touchpad is pressed. Summary of the Invention

[0003] The present invention provides a touchpad bracket, a touchpad, and an electronic input device, which aim to solve the above-mentioned problems.

[0004] According to a first aspect of the embodiments of this application, a touchpad bracket is provided for triggering a touch module of the touchpad; it includes a fixed plate, a connecting plate, a frame, and at least one elastic connecting piece: the fixed plate is fixedly disposed relative to the touchpad, and the fixed plate is disposed opposite to the touch module; the connecting plate surrounds the fixed plate; the frame surrounds the connecting plate, the frame is connected to the touchpad, and moves synchronously with the touchpad; the elastic connecting piece is used to connect the frame, the connecting plate, and the fixed plate; wherein, pressing any position of the touchpad causes the touchpad to move the frame, the frame to move the elastic connecting piece, and the elastic connecting piece to move the connecting plate, so as to realize that the touchpad, the frame, the elastic connecting piece, and the connecting plate move downward synchronously, thereby realizing the contact between the fixed plate and the touch module.

[0005] In the touchpad bracket of the present invention, a transmission component is provided on the fixed plate, the transmission component is disposed opposite to the touch module, and the distance between the transmission component and the touch module is adjustable.

[0006] In the touchpad bracket of the present invention, the transmission component is any one of an adjusting screw, an elastic component, or a telescopic component.

[0007] In the touchpad bracket of the present invention, there are two connecting plates, and the two connecting plates are combined to form an opening, and the fixing plate is disposed in the opening.

[0008] In the touchpad bracket of the present invention, the connecting plate is U-shaped, and the two connecting plates are symmetrically arranged about the center line of the long side of the frame; or the two connecting plates are symmetrically arranged about the center line of the short side of the frame.

[0009] In the touchpad bracket of the present invention, an arch bridge portion is provided at the position where the connecting plates abut each other, and the bridging portions on the two connecting plates are staggered.

[0010] In the touchpad bracket of the present invention, the number of elastic connecting pieces is four, and the four elastic connecting pieces overlap at the four corners of the square formed by the two connecting plates, and the elastic connecting pieces extend to the middle position of the bridging portion; or the number of elastic connecting pieces is two, the elastic connecting pieces overlap the connecting plates, and the elastic connecting pieces extend to the middle position of the bridging portion.

[0011] In the touchpad bracket of the present invention, the elastic connecting piece further includes a plurality of connecting feet extending toward the frame and the fixing plate.

[0012] According to a second aspect of the embodiments of this application, a touch panel is provided, comprising a touch panel, a touch circuit board, and a mounting base arranged sequentially from top to bottom. The touch circuit board includes a touch module in the middle. The touch panel also includes the aforementioned touch panel bracket, which is disposed between the touch circuit board and the mounting base. The touch module is disposed facing the touch panel bracket. When any position of the touch panel is pressed, pressure is transmitted between the frame and the connecting plate through an elastic connecting piece. The touch panel drives the frame to move, the frame drives the elastic connecting piece to move, and the elastic connecting piece drives the connecting plate to move. This causes the touch panel to drive the touch circuit board, the frame, the elastic connecting piece, and the connecting plate to move synchronously downward, thereby achieving contact between the fixed plate and the touch module.

[0013] According to a third aspect of the embodiments of this application, an electronic input device is provided, including the touchpad described above.

[0014] The technical solution provided in this application embodiment may include the following beneficial effects: This application designs a touchpad bracket, which drives the frame to move through the touchpad, and the frame then drives one of the elastic connecting pieces to move through the frame, and then drives the connecting plate to move through the elastic connecting piece, so as to realize that the touchpad, frame, elastic connecting piece and connecting plate move down synchronously, thereby changing the touch module from an untriggered state to a triggered state, and achieving the purpose of stable touch control.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0027] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0028] Please refer to Figure 1 As shown, this invention discloses a touchpad bracket 10 for a touchpad. The touchpad can be fixed by the touchpad bracket 10 and accepts pressing and clicking operations. The touchpad includes a touch panel 20, a touch circuit board 30, a touchpad bracket 10, and a mounting base 40 arranged sequentially from top to bottom. The touch circuit board 30 includes a touch module 31 in the middle, which is disposed towards the touchpad bracket 10. The touch module can be a dome switch or other touch modules.

[0029] like Figure 2 As shown, the touchpad bracket 10 includes a frame 11, a fixing plate 12, a connecting plate 13, and elastic connecting pieces 14. The fixing plate 12 is fixed relative to the touchpad, for example, fixed to the mounting base 40, and the fixing plate 12 is directly opposite the touch module 31. The connecting plate 13 surrounds the fixing plate 12, that is, the fixing plate 12 is disposed within the connecting plate 13. The frame 11 is a square frame that surrounds the connecting plate 13. Multiple elastic connecting pieces 14 are provided, which connect the frame 11, the connecting plate 13, and the fixing plate 12. The elastic connecting pieces 14 serve as connecting and springback mechanisms, and the connection points between the elastic connecting pieces 14 and the frame 11, the connecting plate 13, and the fixing plate 12 act as fulcrums. In this embodiment, the frame 11 is used to fix the touch circuit board 30 and the touch panel 20, so that the touch panel 20, the touch circuit board 30, and the frame 11 move synchronously. The frame 11, fixing plate 12, connecting plate 13, and elastic connecting piece 14 are connected by welding. Pressing any position on the touch panel 20 causes the touch panel to move the frame 11, which in turn moves the elastic connecting piece 14, which in turn moves the connecting plate 13. This allows the touch panel 20, frame 11, elastic connecting piece 14, and connecting plate 13 to move synchronously downwards, thereby achieving contact between the fixing plate 12 and the touch module 31. It should be noted that synchronous downward movement in this context refers to the overall downward movement of the frame 11 and touch panel 20 under the influence of the frame 11, elastic connecting piece 14, and connecting plate 13 when any position on the touch panel 20 is pressed; it does not mean that the downward movement distance of each component is the same.

[0030] The elastic connecting piece 14 is disposed on the side closest to the touch circuit board. That is, the frame 11, the connecting plate 13, and the fixing plate 12 are disposed on the same plane, with these three components on one side of the elastic connecting piece 14, and the touch circuit board on the other side. In this application, the entire fixing plate 12 is fixed, resulting in more fixing methods and a better fixing effect, for example... Figure 2 As shown, it is fixed to the four corners of the fixing plate 12 by four screws.

[0031] It should be noted that the touch module 31 is existing technology, and it will compress or collapse when the external force reaches a certain threshold. When the user presses the touch panel 20 near the center, the touch module 31 is easily compressed or collapsed. However, when the user presses the touch panel 20 from the outer edge, only the outer edge is pressed down, resulting in less pressure on the touch module 31, which may not reach the threshold for compression or collapse. This will affect the user's operation. The touch panel bracket 10 is provided below the touch circuit board to solve this problem. Through the action of the touch panel bracket 10, the touch panel 20 can achieve approximately "parallel movement". Pressing any position on the touch panel causes the frame, elastic connecting piece, and linkage plate to move synchronously, so as to achieve contact between the fixed plate and the touch module. When the user presses one side of the touch panel 20, the other side of the touch panel 20 will move downwards, thereby changing the touch module 31 from an untriggered state to a triggered state, and achieving the purpose of stable touch control.

[0032] When using this device, the user presses one side of the outermost touch panel 20 (e.g., the edge along the length). The pressed side of the touch panel 20 moves downward, causing the touch circuit board 30 and frame 11 on the same side to move downward together. The elastic connecting piece 14 on the same side transmits the downward force of the frame 11 to the side of the connecting plate 13 closest to it. The connecting plate 13 transmits the downward force from the side closest to the pressed position to the other side, thus transferring the force to the other side to cause the connecting plate 13 on the other side to move downward. The connecting plate 13 on the other side then causes the elastic connecting piece 14 on the other side to move downward, and the elastic connecting piece 14 on the other side then causes the other side of the frame 11 to move downward. This causes the touch circuit board 30 and touch panel 20 on the other side to move downward, thereby achieving a parallel movement of the touch circuit board 30. The touch module 31 abuts against the fixing plate 12. Under the support force provided by the fixing plate 12, the touch module 31 is compressed or collapsed to trigger the touch module 31. Since the fixing plate 12 is fixed on the mounting base 40, after the touch module 31 is triggered, under the elastic force of the elastic connecting piece 14, the elastic connecting piece 14 drives the connecting plate 13 to rebound, and the connecting plate 13 then drives the frame 11 to reset, ready for the next press of the touch panel 20 to trigger the touch module 31.

[0033] Please refer to Figure 1As shown, in an optional embodiment, to further facilitate triggering the touch module 31, a transmission member 50 is provided on the fixing plate 12. The transmission member 50 is positioned directly opposite the touch module 31, and the distance between the transmission member 50 and the touch module 31 is adjustable. In some embodiments, the transmission member 50 is an adjusting screw. A threaded hole 121 is provided on the fixing plate 12, and the adjusting screw is installed in the threaded hole 121. The adjusting screw is positioned directly opposite the touch module 31, and the distance the adjusting screw extends out of the fixing plate 12 can be adjusted to achieve different sensitivities. The transmission member 50 can also be configured with other structures, as long as it can adjust the distance between the transmission member 50 and the touch module 31. For example, the transmission member can be a telescopic member or an elastic member.

[0034] like Figures 2-6 As shown, in an optional embodiment, the number of connecting plates 13 is set to two, and the two connecting plates 13 are combined to form an opening, in which the fixing plate 12 is disposed. By having two connecting plates 13, when the elastic connecting piece 14 pushes the connecting plates 13 downwards, the force required is less due to the shorter lever arm, thus reducing the effort needed to press the connecting plates 13 downwards at the same angle, making it more convenient for the user. It is understood that the connecting plates 13 can also be set as a single integral structure, such as a square frame smaller than the frame 11.

[0035] like Figures 2-4 In the illustrated embodiment, the two connecting plates 13 are U-shaped and symmetrically arranged about the centerline of the short side of the frame 11. A bridging portion 133 is provided at the abutting position of the connecting plates 13, and the bridging portions 133 on the two connecting plates 13 are staggered. There are four elastic connecting pieces 14, which overlap at the four corners of the square frame formed by the two connecting plates 13, and extend to the middle of the bridging portion 133.

[0036] Specifically, the openings of the two connecting plates 13 are arranged opposite each other, and the opening formed by the combination of the two connecting plates 13 is slightly larger than the size of the fixed plate 12, which is disposed within this opening. The connecting plate 13 includes a first bottom wall 131 and two first side walls 132. The ends of the first side walls 132 are provided with bridging portions 133, and the bridging portions 133 on the two opposite first side walls 132 are staggered. The number of elastic connecting pieces 14 is set to four. Each elastic connecting piece 14 is L-shaped and includes a first wall 141 and a second wall 142. The first wall 141 of the elastic connecting piece 14 overlaps and adheres to the first side wall 132 of the connecting plate 13; the second wall 142 of the elastic connecting piece 14 overlaps and adheres to the first bottom wall 131 of the connecting plate 13.

[0037] When the user presses the edge of the touch panel 20, it causes the edge of the frame 11 to move downwards. The frame 11 then causes the elastic connecting piece 14 to move downwards. The end of the elastic connecting piece 14 extends to near the middle of the bridging portion 133. Therefore, the elastic connecting piece 14 causes the connecting plate 13 to move downwards. The point where the two connecting plates 13 abut each other moves downwards. The user needs to exert less force, making it convenient to use and improving the user experience. The two bridging portions 133 form a "Z"-shaped interface. The "Z"-shaped interface can achieve synchronous movement without interfering with each other, allowing for free movement. In this embodiment, a gap 15 is provided between the two sides of the fixed plate 12 and the connecting plate 13. The gap 15 serves as a channel for the connecting wire, which passes through the gap 15 to connect to the touch circuit board 30.

[0038] In this embodiment, the elastic connecting piece 14 further includes multiple connecting feet 143, which extend toward the frame 11 and the fixing plate 12. The frame 11, the connecting plate 13, the elastic connecting piece 14, and the fixing plate 12 are connected by welding, so that the frame 11 can drive the elastic connecting piece 14 to move, and the elastic connecting piece 14 in turn drives the connecting plate 13 to move. Specifically, the number of connecting feet 143 can be set to three. One connecting foot 143 is respectively provided at the end of the second wall 142 that is in contact with the first bottom wall 131 toward the fixing plate 12 and the frame 11, and another connecting foot 143 extends from the end of the first wall 141 of the elastic connecting piece 14 toward the frame 11. The number and position of the connecting feet 143 can be set according to actual conditions and are not limited here.

[0039] like Figure 5 and Figure 6 In the illustrated embodiment, two connecting plates 13 are also provided. Both connecting plates 13 are U-shaped and symmetrically arranged about the centerline of the long side of the frame 11. A bridging portion 133 is provided at the abutting position of the connecting plates 13, and the bridging portions 133 on the two connecting plates 13 are staggered. There are also two elastic connecting pieces 14. The structure of the elastic connecting pieces 14 is similar to that of the connecting plates 13. The elastic connecting pieces 14 overlap the connecting plates 13 and extend to the middle position of the bridging portion 133.

[0040] Specifically, in this embodiment, the openings of the two connecting plates 13 are arranged opposite to each other. The opening formed by the combination of the two connecting plates 13 is larger than slightly larger than the size of the fixed plate 12. The fixed plate 12 is disposed within this opening. The connecting plate 13 includes a second bottom wall 134 and two second side walls 135. The ends of the second side walls 135 are provided with bridging portions 133, and the bridging portions 133 on the two opposing second side walls 135 are staggered. The elastic connecting piece 14 is also U-shaped, including a third bottom wall 144 and two third side walls 145. The third bottom wall 144 overlaps the second bottom wall 134, and the third side walls 145 overlap the second side walls 135. The end of the third side wall 145 extends to near the middle position of the bridging portion 133. In this embodiment, both the second bottom wall 134 and the third bottom wall 144 are provided with slots 16. The slots 16 serve as channels for connecting wires, which pass through the slots 16 to connect to the touch circuit board 30. In this embodiment, the fixed plate 12 is configured as an H-shape. The connecting feet 143 can be set to four, with two connecting feet 143 extending from the third bottom wall 144 toward the short side of the frame 11, and the other two connecting feet 143 extending from the third bottom wall 144 toward the fixing plate 12.

[0041] like Figure 1 As shown, this application also protects a touchpad 100, which includes a touch panel 20, a touch circuit board 30, a touchpad bracket 10, and a mounting base 20 arranged sequentially from top to bottom. The touch circuit board 30 includes a touch module 31 in the middle, which faces the touchpad bracket 10. Pressing any position on the touch panel 20 transmits pressure between the frame 11 and the connecting plate 13 through the elastic connecting piece 14. The touch panel 20 moves the frame 11, the frame 11 moves the elastic connecting piece 14, and the elastic connecting piece 14 moves the connecting plate 13. This causes the touch panel 20 to move the touch circuit board 30, the frame 11, the elastic connecting piece 14, and the connecting plate 13 simultaneously downward, so as to achieve contact between the fixing plate 12 and the touch module 31.

[0042] like Figure 7 As shown, this application also relates to an electronic input device, which can be an electronic device with touch functionality, such as a laptop computer. The electronic input device of this application includes the aforementioned touchpad 100.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
