[0032] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0033] See also Figure 2 and Figure 3 The touch panel mechanism 100 for electronic products of the present invention comprises a base frame 10, a stabilizing rod 20, a touch panel 30 stacked with the base frame 10 along a first direction (see the Z-axis direction), and a connecting stopper 40 extending along the first direction. The touch panel 30 can move closer to or away from the base frame 10 to meet the requirements that the touch panel 30 can move closer to the base frame 10 when pressed by an operator, and can move away from the base frame 10 when the touch panel 30 is free from the pressure applied by the operator. The stabilizing rod 20 comprises a central section 21 extending along a second direction (see the Y-axis direction) and a bending section 22 bent relative to the central section 21. The central section 21 is rotatably mounted on the touch panel 30. An assembly structure 11 is provided on the base frame 10. The bending section 22 is assembled on the assembly structure 11, so that the touch panel 30 drives the bending section 22 to perform a pivoting movement when moving closer to or away from the base frame 10. The connection stopper 40 is assembled and connected with the touch panel 30. The connection stopper 40 passes through the base frame 10 with clearance fit. The connection stopper 40 is provided with a blocking structure 41 protruding outward along a direction intersecting with the first direction (for example, but not limited to the second direction and / or the third direction). When the touch panel 30 moves away from the base frame 10 to a preset distance, the blocking structure 41 blocks the base frame 10 passed by the connection stopper 40. When the touch panel 30 moves toward or away from the base frame 10, the base frame 10 passed by the connection stopper 40 slides relative to the connection stopper 40 along the third direction (see the X-axis direction) through the pivoting movement of the bending section 22; wherein, the first direction, the second direction, and the third direction are mutually intersecting. The first direction and the third direction together constitute XYZ in the three-dimensional coordinate system. For example, the first direction is the Z-axis direction in the three-dimensional coordinate system, the second direction is the Y-axis direction in the three-dimensional coordinate system, and the third direction is the X-axis direction in the three-dimensional coordinate system. Of course, according to actual needs, their relationship can be replaced with each other, so it is not limited to the figures shown; in other embodiments, the central section 21 can be rotatably assembled on the base frame 10, and correspondingly, the assembly structure 11 is provided by the touch panel 30; in addition, the connection limiter 40 can be made to be assembled and connected with the base frame 10, and correspondingly, the touch panel 30 is passed through by the connection limiter 40 at intervals, so that the blocking structure 41 is used to block and cooperate with the touch panel 30. More specifically, as follows:

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, there are two connection limiters 40, and the two connection limiters 40 are arranged in a spaced relationship along the second direction to ensure the reliability of the connection and limit between the base frame 10 and the touch panel 30. Of course, according to actual needs, the connection limiters 40 can also be selected to be one or three, so it is not limited to the figure. Specifically, as shown in FIG. Figure 6 , Fig. 9 and Fig.10 As shown, the connection stopper 40 has a thread structure 42 at a position away from the blocking structure 41, and the connection stopper 40 is threadedly connected to the touch panel 30 through the thread structure 42. This design improves the convenience of assembly operation between the connection stopper 40 and the touch panel 30, and further simplifies the assembly process of the touch panel mechanism 100 for electronic products of the present invention. For example, in Figure 6 , Fig. 9 and Fig.10 In the embodiment, the thread structure 42 of the connection limiter 40 is an external thread, and of course, it can also be an internal thread. It should be noted that since the connection limiter 40 is provided with the thread structure 42, the connection limiter 40 can be screwed into or out of the touch panel 30 by screwing, so a structure that facilitates the operator to screw the connection limiter 40 can be provided on the blocking structure 41, such as but not limited to a cross groove structure; in addition, since the connection limiter 40 is threadedly connected to the touch panel 30 through the thread structure 42, a matching structure is provided on the touch panel 30 accordingly. When the thread structure 42 is an external thread, the matching structure is an internal thread, such as a nut 60; when the thread structure 42 is an internal thread, the matching structure is an external thread, such as a screw.

[0035] like Figure 2 , Figure 3 , Figure 6 , Fig. 9 and Fig.10 As shown, the touch panel 30 is provided with a bracket 50 protruding toward the base frame 10. The bracket 50 is provided with a circular hole 51 matching the contour of the center segment 21 and a channel 52 for the center segment 21 to be pressed into or pulled out of the circular hole 51 along a first direction parallel to the first direction. The dimension D of the intersection of the channel 52 and the circular hole 51 is smaller than the diameter of the circular hole 51. With the cooperation of the circular hole 51 and the channel 52, the center segment 21 is easily assembled and disassembled at the circular hole 51 on the one hand, and the center segment 21 is effectively prevented from accidentally falling off from the circular hole 51 on the other hand. At the same time, with the help of the bracket 50, the center segment 21 is indirectly assembled to the touch panel 30 through the bracket 50. Specifically, in Figure 7 and Figure 8In the embodiment, the bracket 50 is further provided with an inclined structure 54 for enlarging the size of the end of the channel 52 away from the circular hole 51. Preferably, there are two inclined structures 54 arranged in an inverted "eight" shape to further facilitate the center section 21 to be pressed into the circular hole 51. More specifically, in Figure 7 In the figure, six support clamps 53 are provided on the bracket 50 and are arranged in rows along the second direction. Each support clamp 53 is provided with a circular hole 51 and a channel 52. This design can reduce the size occupied by the circular hole 51 on the bracket 50 along the second direction, reduce the contact position between the center segment 21 and the circular hole 511, thereby improving the rotational fit accuracy between the center segment 21 and the circular hole 51. It should be noted that, when the bracket 50 is provided by the touch panel 30, the connection limiter 40 is threadedly connected to the bracket 50 via a threaded structure 42. Correspondingly, a structure matching the threaded structure 42 is provided on the bracket 50. For example, a nut 60 is embedded in the bracket 50. Of course, threads may also be directly processed on the bracket 50. In addition, in other embodiments, the bracket 50 may be provided by the base frame 10, so that the solution containing the center section 21 rotatably assembled on the base frame 10 is indirectly assembled on the base frame 10 through the bracket 50. Among them, the bracket 50 may be provided on the base frame 10 or the touch panel 30 by assembly or integrated molding.

[0036] like Figures 2 to 5 As shown, the stabilizing rod 20 is an elastic rod, the bending section 22 includes an offset section 221 offset parallel to the central section 21 and an intermediate section 222 connected between the offset section 221 and the central section 21, the offset section 221 is rotatably assembled to the assembly structure 11, for example but not limited to rotatably inserted into the assembly structure 11, and the intermediate section 222 is arranged to be inclined relative to the first direction when the blocking structure 41 resists the base frame 10 through which the connected limiting member 40 passes, for example but not limited to Figure 4 As shown in the figure, the front upper and rear lower inclined arrangement; the middle section 222 approaches the base frame 10 together with the central section 21 during the movement of the touch panel 30 toward the base frame 10, so that the stabilizing bar 20 provides a restoring elastic force for the touch panel 30 to move away from the base frame 10; with the arrangement of the offset section 221 and the middle section 222, on the one hand, the touch panel 30 has a higher sensitivity and a better feel when moving relative to the base frame 10, and on the other hand, the touch panel 30 can be automatically reset. Specifically, as Figure 2 , Figure 3 and Figure 5As shown, a bending section 22 is provided on each of the two opposite ends of the center section 21, and the offset sections 221 on the two opposite ends of the center section 21 are aligned with each other along the second direction. There are two assembly structures 11, and the offset section 221 on one end of the center section 21 can be rotatably assembled to one assembly structure 11, and the offset section 221 on the other end of the center section 21 can be rotatably assembled to the other assembly structure 11. The purpose of this design is to further improve the sensitivity and feel of the touch panel 30 relative to the base frame 10 and the reset ability of the touch panel 30. More specifically, in Figure 2 , Figure 3 and Figure 5 In the figure, the assembly structure 11 is a suspended bending sheet structure, and the two bending sheet structures are located between the middle sections 222 on the opposite ends of the central section 21 along the second direction, which more effectively improves the sensitivity, feel and reset ability of the touch panel 30 relative to the base frame 10. For example, the offset segments 221 on the opposite ends of the center segment 21 are aligned and arranged close to each other, and the middle segments 222 on the opposite ends of the center segment 21 are parallel to each other, so that the stabilizing bar 22 as a whole is a square ring profile open at both ends, so as to effectively improve the sensitivity, feel and reset ability of the touch panel 30 relative to the base frame 10. Of course, according to actual needs, the offset segments 221 on the opposite ends of the center segment 21 can also be aligned and arranged away from each other, or one is aligned and arranged close to the other. In addition, the middle segments 222 on the opposite ends of the center segment 21 can also be made into a non-parallel relationship, for example, one is perpendicular to the center segment 21 and the other is inclined to the center segment 21, or both are inclined relative to the center segment 21 at the same time; in addition, the bending sheet structure is a right-angle bending sheet structure, but is not limited to this. It should be noted that the bent section 22 can be connected to the central section 21 by assembly, or can be bent directly from the central section 21; in addition, the assembly structure 11 can be provided on the base frame 10 by assembly, or can be bent directly from the base frame 10. In addition, the above-mentioned parallel offset means that the offset section 221 and the central section 21 are parallel to each other, and the two do not overlap in the extension direction of the central section 21.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, the first ends of the touch panel 30 and the base frame 10 are snap-connected, and the central section 21 is located at the second end opposite to the touch panel 30 , that is, the stabilizing bar 20 is arranged at the second ends of the touch panel 30 and the base frame 10 , but not limited thereto.

[0038] In summary, the assembly method of the touch panel mechanism 100 for an electronic product of the present invention comprises the following steps: (1) assembling the central section 21 to the touch panel 30, specifically, assembling it to the bracket 50 provided on the touch panel 30 and protruding toward the base frame 10, and at the same time, assembling the bent section 22 to the assembly structure 11 provided on the base frame 10; and (2) passing the connecting limit member 40 through the base frame 10 from the side of the base frame 10 facing away from the touch panel 30 in a clearance fit and then assembling and connecting with the touch panel 30, specifically, assembling and connecting with the bracket 50 provided on the touch panel 30, and making the blocking structure 41 of the connecting limit member 40 located at the side of the base frame 10 facing away from the touch panel 30; specifically, the connecting limit member 40 is assembled and connected with the touch panel 30 by means of a threaded connection, specifically, it is threadedly connected with the bracket 50 provided on the touch panel 30. It is understandable that in other embodiments, the central section 21 can be assembled on the base frame 10, and correspondingly, the bent section 22 is assembled on the assembly structure 11 provided by the touch panel 30. At this time, the connecting limit member 40 passes through the touch panel 30 with a clearance fit from the side of the touch panel 30 facing away from the base frame 10 and is then assembled and connected with the base frame 10, and the blocking structure 41 of the connecting limit member 40 is located on the side of the touch panel 30 facing away from the base frame 10.

[0039] Combination Fig. 9 and Fig.10 Initially, the base frame 10 is in the maximum distance from the touch panel 30 due to the blocking cooperation with the blocking structure 41. Fig. 9 When the operator applies a force F to the touch panel 30, the touch panel 30 moves closer to the base frame 10; and during the movement of the touch panel 30 closer to the base frame 10, Fig. 9 The middle section 222 in the middle section 222 and the center section 21 together make a clockwise pivotal swing motion around the offset section 221, so that the middle section 222 and the center section 21 move closer to the base frame 30, and the base frame 10 moves relative to the connection limiter 40. Fig.10 The X-axis in the positive sliding direction, the state is shown in Fig.10 As shown in the enlarged view in FIG. , the stabilizing bar 20 provides a restoring elastic force for the touch panel 30 to be restored.

[0040] Compared with the prior art, the touch panel mechanism 100 for electronic products of the present invention further comprises a connection stopper 40 extending along the first direction, the connection stopper 40 is assembled and connected with one of the touch panel 30 and the base frame 10, the connection stopper 40 passes through the other of the touch panel 30 and the base frame 10 with clearance fit, and a blocking structure 41 protruding outwardly in a direction intersecting with the first direction is provided on the connection stopper 40, and the blocking structure 41 resists the touch panel 30 or the base frame 10 passed by the connection stopper 40 when the touch panel 30 moves away from the base frame 10 to a preset distance, and the touch panel 30 or the base frame 10 passed by the connection stopper 40 is blocked when the touch panel 30 moves toward or away from the base frame 10. During the movement, the bending section 22 slides relative to the connecting limit piece 40 along the third direction through the pivoting movement of the bending section 22; therefore, during assembly, the central section 21 of the stabilizing bar 20 is first assembled to one of the touch panel 30 and the base frame 10, and the bending section 22 of the stabilizing bar 20 is assembled to the assembly structure 11 provided for the other of the touch panel 30 and the base frame 10, and then the touch panel 30 and the base frame 10 are connected and limited by means of the connecting limit piece 40, so that the assembly of the touch panel mechanism 100 for electronic products of the present invention is simpler, the service life is longer, and the matching relationship between the bending section 22 and the assembly structure 11 is not restricted. In addition, the touch panel mechanism 100 for electronic products of the present invention also has the advantages of high sensitivity and good hand feel.

[0041] It is worth noting that when the bending section 22 includes a middle section 222 bent 90 degrees relative to the central section 21 and an offset section 221 bent 90 degrees relative to the middle section 222, the middle section 222 performs a pivoting motion around the offset section 221 together with the central section 21 during the movement of the touch panel 30 toward or away from the base frame 10; when the bending section 22 is made into the existing Figure 1 When the bending section 221 in the middle, the bending section 22 at this time pivots around the center section 21 together with the center section 21 during the movement of the touch panel 30 towards or away from the base frame 10; when the connection limit member 40 has a blocking structure 41 and a threaded structure 42, the connection limit member 40 at this time is a non-standard stud.

[0042] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
