[0048] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0049] In addition, the terms "installed", "set", "provided with", "opened", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0051] The technical solution of the present invention will be further described below in conjunction with the first embodiment of this implementation mode and the accompanying drawings.

[0052] The structural diagram of the global pressing computer touch panel in the first embodiment of this implementation mode is as follows Figure 1 As shown, including:

[0053] The touch components and the elastic support member used to support the touch components are stacked; the middle area between the touch components and the elastic support member overlaps, so that the center of gravity of the full-range pressing overlaps, preventing the problem of virtual position and stuck position caused by offset.

[0054] The elastic support member adopts a spring-type structure to support the touch control component, thereby reducing the problems of complex process and high cost of the previous connecting rod structure. The spring-type mechanism has the advantages of simple assembly process and low manufacturing cost.

[0055] In addition, the touch control assembly includes: a touch control panel 1 and a PCB board 2 connected to the touch control panel 1; the touch control panel 1 and the PCB board 2 are attached to each other to quickly receive pressing feedback.

[0056] The elastic support member includes a limiting bracket 4 and an elastic bracket 6 which are arranged in layers. The limiting bracket 4 is used to support and connect the PCB board 2 , and the elastic bracket 6 is connected to a side of the limiting bracket 4 which faces away from the PCB board 2 .

[0057] The elastic bracket 6 is provided with an outwardly protruding spring piece, which is a sheet metal spring piece 7 of an integrated structure; the outwardly protruding direction of the sheet metal spring piece 7 is the direction in which the elastic bracket 6 moves away from the limiting bracket 4, thereby enhancing the elastic deformation rate of the sheet metal spring piece 7.

[0058] The sheet metal spring piece 7 is used to deform when any position of the touch panel 1 is pressed, and the limiting bracket 4 limits the deformation direction of the middle area of ​​the sheet metal spring piece 7, so that when one side of the sheet metal spring piece 7 moves downward, the other side moves downward synchronously, maintaining the overall displacement of the touch component, enhancing the user's hand feel experience, and being simple to manufacture and low in cost.

[0059] refer to Figure 2 , Figure 2 This is a schematic diagram of the back structure of the full-range pressing computer touchpad provided in the embodiment of the present application. Figure 2 It can be seen that when specifically limiting the middle area of ​​the sheet metal spring piece 7, a limiting structure is provided on the limiting bracket 4, and the limiting structure is pressed against the outer side of the middle area of ​​the sheet metal spring piece 7 to shield the middle position of the sheet metal spring piece 7.

[0060] When either side of the sheet metal spring piece 7 moves downward, the middle part of the sheet metal spring piece 7 cannot deform outward, so that under the tension of the sheet metal spring piece 7, the opposite side of the touch component is driven downward to keep the left and right balance and synchronous displacement.

[0061] refer to Figure 3 , is an exploded view of the global pressing computer touch pad provided in the embodiment of the present application; in order to make the global pressing touch pad 1 closely matched, by Figure 3 As can be seen in the figure, the limiting bracket 4 is connected to the side of the PCB board 2 facing away from the touch panel 1 through two first frames 3. The first frame 3 is attached between the limiting bracket 4 and the PCB board 2, so that the pressure is transmitted to the limiting bracket 4 after the touch panel 1 is subjected to pressure.

[0062] The elastic bracket 6 is connected to the side of the limit bracket 4 facing away from the PCB board 2 through the second frame 5. The second frame 5 is attached between the limit bracket 4 and the elastic bracket 6. It can be seen that the touch panel 1, the PCB board 2, the first frame 3, the limit bracket 4, the second frame 5 and the elastic bracket 6 are all plate-shaped, so that a close fitting relationship is formed between the multiple plates after being bonded or screwed. After the touch panel 1 is subjected to a pressing force, the pressing force is transmitted to the sheet metal spring 7 on the elastic bracket 6, and the sheet metal spring 7 is deformed. Under the action of the limit structure, the left and right sides of the touch component are balanced and displaced synchronously.

[0063] Continue to refer Figure 4 and Figure 5 , Figure 4 and Figure 5 The structural diagram and side view of the elastic bracket provided in the embodiment of the present application. Figure 4 It can be seen that the elastic bracket 6 is provided with a first clearance space 61 for accommodating the sheet metal spring piece 7; the sheet metal spring piece 7 is installed in the first clearance space 61, and the elastic bracket 6 and the sheet metal spring piece 7 can be integrated by stamping or welding.

[0064] The sheet metal spring piece 7 includes a middle connection part 71 and bifurcated parts 72 mirror-imaged at both ends of the middle connection part 71; the bifurcated parts 72 at both ends are respectively connected to the elastic bracket 6 and have a certain inclination. The sheet metal spring piece 7 has a simple shape and is easy to process. The inclination provides an elastic space for the sheet metal spring piece 7, and the angle changes after being pressed. At the same time, screw holes can be opened in the bifurcated parts 72 at both ends, and the opened screw holes are used to connect with the fixed base.

[0065] When a certain inclination exists between the forked portion 72 at both ends and the elastic bracket 6, a bending member 73 is used, and the bending member 73 is obliquely connected between the ends of the forked portion 72 at both ends and the elastic bracket 6; Figure 4 As shown in the figure, the forked portions 72 at both ends have four connection ends with the elastic bracket 6, and four bending pieces 73 are provided, and the bending pieces 73 are connected to the ends of the two forked portions 72 one by one, and are connected to the elastic bracket 6. Of course, the forked portions 72 at both ends can also be three-forked or four-forked, and the connection ends also have six or eight.

[0066] The bending member 73 can be an integral structure with the forked parts 72 at both ends. The forked parts 72 made of sheet metal are impact-bent at their connecting ends. The sheet metal material is made of a material with strong rigidity, so that the bending angle cannot change due to long-term pressing.

[0067] At the same time, in order to make it easier for the user to press, a strip groove 74 is provided at the connection between the bending piece 73 and the corresponding fork portion 72, so as to reduce the force required when the bending piece 73 is bent.

[0068] refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 The schematic diagram and side view of the structure of the limit bracket provided in the embodiment of the present application. When the limit structure is set to limit the middle connection part 71 of the sheet metal spring piece 7, a second clearance space 42 is opened on the limit bracket 4, and the limit structure extends to the second clearance space 42 and presses against the middle connection part 71. The limit structure and the limit bracket 4 are an integral structure, and after the elastic bracket 6 is connected to the limit bracket 4, the limit structure is pressed on the middle connection part 71 of the sheet metal spring piece 7.

[0069] Specifically, the limiting structure includes a bent pressing plate 41 connected to one side of the limiting bracket 4 , and the bent pressing plate 41 presses against the middle part of the outer side of the middle connecting portion 71 , thereby limiting the middle connecting portion 71 from deforming outward.

[0070] The bending height of the bending pressure plate 41 is the same as the convex height of the sheet metal spring 7; the intermediate connection part 71 is pressed with equal force. By pressing the intermediate connection part 71 of the sheet metal spring 7 with equal force by the bending pressure plate 41, after any position of the touch panel 1 is pressed, the angle of the bending part 73 on the force-bearing side changes, and the intermediate connection part 71 cannot be deformed under the pressure of the bending pressure plate, so that under the tension of the sheet metal spring 7, the angle of the bending part 73 on the opposite side changes synchronously, so that the touch component is displaced as a whole, with good hand feeling and high sensitivity; and the sheet metal spring 7 with simple processing technology is used, so that the manufacturing cost is greatly reduced and the durability is improved.

[0071] In the embodiment of the present application, a limiting bracket 4 is used to support the touch component and to limit the sheet metal spring piece 7. When the touch component is pressed, the touch component is kept balanced over the entire area due to the tension of the sheet metal spring piece 7, thereby maintaining a high user experience. The spring-type structure is adopted, the manufacturing process is simple, and the production cost is reduced.

[0072] The second embodiment of the present invention relates to a full-range pressing computer touch pad.

When the touch component 100 is pressed, the touch component 100 is kept balanced in the entire area due to the tension of the spring 211.

[0076] It is understandable that the touch control assembly 100 includes a touch panel 110 and a circuit board 120 , and the circuit board 120 is sandwiched between the touch panel 110 and the elastic support member 200 .

[0077] Please refer to Fig. 9 and Fig.10In some embodiments, the elastic support member 200 includes a return bracket 230, which is attached to the side of the spring 211 away from the touch component 100.

[0078] Please refer to Fig.11 Fig.12 Furthermore, the limiting structure 221 is L-shaped, and the surface of the limiting structure 221 facing the touch component 100 is attached to the surface of the return bracket 230 away from the touch component 100. In this way, the L-shaped limiting structure 221 limits the return bracket 230 and the spring piece 211. When the touch component 100 is subjected to an external force, the elastic bracket 210 is pushed to move toward the return bracket 230, thereby squeezing the spring piece 211. At this time, since the return bracket 230 is fixed in position by the L-shaped limiting structure 221, the spring piece 211 is released toward one side of the touch component 100 under the action of the return bracket 230, and pushes the touch component 100 to move in the direction away from the return bracket 230, so as to realize the reset of the full-range pressed computer touchpad after the external force is removed.

[0079] Optionally, the limiting bracket 220 may also be in a circular ring shape, an elliptical ring shape or other shapes, as long as it is provided with an L-shaped limiting structure 221 and does not affect the assembly of other components of the full-range pressing computer touchpad. The embodiment of the present invention does not make specific limitations on this.

[0080] Please refer to Fig.13In some embodiments, there are at least four bending portions 232, each bending portion 232 extends in a direction away from the touch assembly 100, there are at least four limiting through holes 232a, and they correspond to the bending portions 232 one by one, the base 212 includes two opposite sides, there are two reciprocating rods 240, and the two reciprocating rods 240 are respectively arranged on the two opposite sides of the base 212, each rod body 241 is a straight line, each rod body 241 has two opposite ends, each end of each rod body 241 is provided with a connecting portion 242, and each connecting portion 2 The return bracket 230 has two opposite ends, one end of each connecting portion 242 is connected to one end of the rod main body 241, and the other end of each connecting portion 242 is bent and extended toward the middle of the rod main body 241. The connecting portion 242 corresponds to the limiting through hole 232a one by one, and one end of the connecting portion 242 that is bent and extended toward the middle of the rod main body 241 passes through the limiting through hole 232a. The return bracket 230 includes at least four bent portions 232, and each bent portion 232 is bent and extended away from the touch component 100, and the limiting through holes 232a are at least four and correspond to the bent portions 232a. The folding portions 232 are arranged in a one-to-one correspondence with the bending portions 232, which can ensure that there is a height difference between the limiting through hole 232a and the base 212. The base 212 includes two opposite sides. There are two return rods 240, which are respectively arranged on the two opposite sides of the base 212. The rod body 241 of each return rod 240 is in a straight line shape and has two opposite ends. Both ends are provided with a connecting portion 242. Each connecting portion 242 has two opposite ends, one end is connected to the rod body 241, and the other end is bent and extended toward the middle of the rod body 241. The connecting portion 242 and The limiting through holes 232a correspond one to one, and one end of the rod body 241 that bends and extends toward the middle of the limiting through hole 232a passes through the limiting through hole 232a. In this way, when the touch pad 110 is pushed by an external force to move the base 212 toward the return bracket 230, there are at least four limiting through holes 232a on the return bracket 230, and the connecting part 242 of the return rod 240 passes through the limiting through holes 232a one to one and abuts against the inner wall of the limiting through hole 232a, so that the force distribution of the full-area pressing computer touchpad is more balanced, and the touch feel of the full-area pressing computer touchpad is optimized.

[0081] Take a connection portion 232 as an example. Fig.14 (a) and Fig.14As shown in (b), when the touch pad 110 is acted upon by an external force F and moves toward the return bracket 230, the touch pad 110 pushes the circuit board 120 to move toward the return bracket 230, and further pushes the base 212 to move toward the return bracket 230. At this time, the spring sheet 211 is compressed and deformed toward the return bracket 230, generating an elastic force. At the same time, the connecting portion 242 rotates along the P1 direction with the main body of the return rod as the rotation axis until it abuts against the inner wall of the limit through hole 232a toward the return rod. At this time, the return rod abuts against the base 212, preventing the base 212 from continuing to move toward the return bracket 230. The base 212 The circuit board 120 is pressed against, and the touch pad 110 is further prevented from continuing to move under the action of the external force F, so that the touch pad 110 can be prevented from collapsing or getting stuck when the external force F acts on it. In addition, even if the external force F acts on any position of the touch pad 110, when the touch pad 110 pushes the base 212 toward the return bracket 230, the reciprocating rod 240 rotates, driving the connecting portion 242 at the other end to rotate. Driven by the connecting portions 242 at both ends of the reciprocating rod 240, the side of the touch pad 110 where the external force F acts moves synchronously, so that the touch effect of the computer touch pad when pressed in the whole area is more balanced and the feel is better. When the external force F is removed, such as Fig.14 As shown in (c), the spring piece 211 returns to its original shape under the action of the elastic force, thereby pushing the base 212 to move in the direction away from the return bracket 230. The circuit board 120 and the touch pad 110 are pushed by the base 212 to return to the position before the external force F acts. At this time, the connecting portion 242 of the return rod 240 is driven by the base 212 and rotates along the P2 direction with the rod body 241 as the rotation axis until it abuts against the inner wall of the limiting through hole 232a away from the return rod 240, preventing the base 212 from moving further away from the return bracket 230, preventing the base 212, the circuit board 120 and the touch pad 110 from being separated from the return bracket 230 under the action of the elastic force of the spring piece 211, thereby ensuring the integrity of the touch structure.

[0082] It can be understood that, under the action of external force and after the external force is removed, the movement process of the other connecting parts 242 is the same as the movement process of the above-mentioned connecting parts 242.

The main body 241 of the two reciprocating rods 240 is respectively rotatably connected to the two opposite sides of the base 212. In this way, when the touch panel 110 is pushed by an external force to the base 212 toward the return stroke, When the bracket 230 moves, there are two limit through holes 232a on the return bracket 230, and the connecting part 242 of the return rod 240 passes through the limit through hole 232a and abuts against the inner wall of the limit through hole 232a, so that the force distribution of the full-area pressing computer touchpad is more balanced, and the touch feel of the touchpad is optimized.
