[0028] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0029] An embodiment of the utility model provides a touchpad structure, including a shell, a frame and a bracket, which are connected to form a support structure of the touchpad, wherein the shell includes installation positions for the frame and the bracket, and provides installation space for components such as a touchpad mainboard; the frame is used to be connected to the shell and tightly connected to other components of the touchpad, and the bracket and the frame are superimposed and arranged to improve the structural strength of the touchpad pressing position.

[0030] The following describes in detail the components of the touch panel structure provided by the embodiment of the utility model, as well as the connection relationship and position relationship between the components in conjunction with the accompanying drawings.

[0031] like Figures 1 to 4As shown, in the embodiment of the utility model, a hollow touch panel mounting position is provided on the housing 1; the frame 2 is provided at the touch panel mounting position and connected to the housing 1. The contour shape of the touch panel mounting position (hollow hole) is the same as the contour shape of the frame 2, and the size of the frame 2 is slightly smaller than the size of the touch panel mounting position. When the two are installed, the frame 2 is placed at the touch panel mounting position, and the side end of the frame 2 is connected to the inner wall of the touch panel mounting position, so that the frame 2 and the housing 1 are an integrated structure.

[0032] The side end of the frame 2 is partially connected to the inner wall of the touch panel installation position, and the remaining non-connected positions have a certain distance of gap. For example, the distance between the side end of the frame 2 and the inner wall of the touch panel installation position is not less than 1 mm.

[0033] The connection between the side end of the frame 2 and the inner wall of the touch panel installation position includes: the front end of the frame 2 is connected to the shell 1 through a pressing elastic arm 21; the pressing elastic arm 21 is curved, one end of which is connected to the frame 2 and the other end is connected to the shell 1, and the pressing elastic arm 21 itself can be deformed, that is, when subjected to a pressing force, the pressing elastic arm 21 provides a certain reset elastic force and is deformed, and when the pressing force is eliminated, the pressing elastic arm 21 is reset. The rear end of the frame 2 is connected to the shell 1 through a fixed connection rib 24, for example, a plurality of fixed connections are arranged at intervals along the length direction of the rear end of the frame 2, and the fixed connection rib 24 is integrally formed with the shell 1 and the frame 2.

[0034] The rear end of the frame 2 is provided with elastic connecting ribs 25 at two corners, and the two corners of the rear end of the frame 2 are connected to the housing 1 through the elastic connecting ribs 25. The elastic connecting ribs 25 have a certain deformation capacity, wherein the elastic connecting ribs 25 are basically not subjected to force in the initial state, which can prevent the two sides of the touch panel from warping or collapsing.

[0035] Continue to refer Figures 1 to 4 As shown, two pressing elastic arms 21 are provided at the front end of the frame 2, and a supporting elastic arm 11 is provided between the two pressing elastic arms 21. The two pressing elastic arms 21 are arranged opposite to the buttons of the touch pad, and the supporting elastic arm 11 is arranged opposite to the switch of the touch pad. For example, the supporting elastic arm 11 is connected to the shell 1, and a accommodating hole for the supporting elastic arm 11 is provided on the frame 2 at a position opposite to the supporting elastic arm 11; the bracket 3 is overlapped with the back side of the front end of the frame 2, and mounting holes 31 are respectively provided on both sides and the middle of the bracket 3, and screw columns 12 arranged opposite to the mounting holes 31 are respectively provided on both sides of the touch pad mounting position on the shell 1 and on the back side of the supporting elastic arm 11.

[0036] After the bracket 3 and the front end of the frame 2 are overlapped, the mounting holes 31 at different positions are arranged opposite to the corresponding screw columns 12, and screws are screwed on the mounting holes 31 and the screw columns 12 respectively to achieve the connection between the bracket 3 and the frame 2. Among them, the screw column 12 is also arranged on the back side of the supporting elastic arm 11 (located in the middle of the front end of the frame 2). After the screw is embedded, the frame 2 and the bracket 3 can be closely attached to the locking screw of the touch panel switch, thereby ensuring the stability of the gap between the touch panel switch and the frame 2 and the bracket 3, so as to improve the stability of the pressing stroke.

[0037] In the embodiment of the utility model, the frame 2 further includes a stopper 22, which is located at the back side of the front end of the frame 2 and has a set height. The bracket 3 is provided with a through hole 32; when the bracket 3 is superimposed on the back side of the front end of the frame 2, the end of the stopper 22 passes through the through hole 32 and is engaged with the bracket 3. The stopper 22 is engaged with the bracket 3 to form a one-way limit stop structure. Compared with the existing screw fastening method, the stopper 22 engagement method can more stably and reliably control the size and avoid the potential risk of the screw loosening due to long-term reciprocating motion after the screw is locked.

[0038] For example, the frame 2 includes two stoppers 22, and the two stoppers 22 are respectively located on one side of the two pressing elastic arms 21; the bracket 3 is provided with two through holes 32, which are respectively connected to the two stoppers 22. Or, for example, the two stoppers 22 are symmetrically arranged around the center of the frame 2, and the ends of the two stoppers 22 are provided with hooks 23 arranged opposite to each other, and the frame 2 is limited in the pressing direction by the hooks 23.

[0039] Continue to refer Figures 1 to 4 As shown, a connecting hook and a connecting screw column are also provided at the front end of the frame 2, and the connecting hook and the connecting screw column are respectively used to connect with the outer shell, and the outer shell is connected with the shell 1 to form an overall shell 1 structure at the system end, and correspondingly, avoidance holes or avoidance gaps corresponding to the connecting hook and the connecting screw column are provided on the bracket 3.

[0040] For example, a positioning column is provided at the front end of the frame 2 on one side of the screw column 12, and correspondingly, a positioning hole is provided on the bracket 3 on one side of the mounting hole 31. When the bracket 3 and the front end of the frame 2 are superimposed, the mounting hole 31 and the screw column 12 are arranged opposite to each other, and the end of the positioning column is inserted into the positioning hole, so that the mounting hole 31 and the screw column 12 can be quickly positioned, and an anti-fool effect can be achieved.

[0041] In the embodiment of the utility model, a plurality of reinforcing ribs 33 are provided on the bracket 3 along the length direction. Each reinforcing rib 33 has a certain length and is provided along the length direction of the bracket 3. The strength of the bracket 3 can be effectively increased by providing the reinforcing rib 33, ensuring that the bracket 3 can provide stable support during the pressing operation. In the embodiment of the utility model, the material of the bracket 3 is metal, for example, the material can be steel, aluminum or alloy material with a certain hardness, etc. In the embodiment of the utility model, the material of the bracket 3 is not limited.

[0042] The embodiment of the utility model further provides an electronic product, including the above-mentioned touch panel structure. For example, the electronic product is a laptop computer, and the touch panel structure is arranged on the system end of the laptop computer. For example, when the shell of the laptop computer is manufactured, the shell 1 and the frame 2 are integrally manufactured, which ensures the connection strength between the shell 1 and the frame 2 and optimizes the production process, thereby achieving the purpose of improving efficiency and saving costs.

[0043] The utility model provides a touch panel structure and electronic product, wherein a bracket 3 is superimposed on the front end of a frame 2, wherein the bracket 3 is made of metal, and the overlap of the two can further enhance the strength of the touch panel pressing area; and a screw column 12 is provided in the middle position of the front end of the touch panel, and after the screw column 12 is embedded, the frame 2 and the locking screw of the touch panel switch can be closely attached, thereby ensuring the stability of the gap between the touch panel switch and the frame 2 and the bracket 3, and avoiding the feeling of collapse caused by insufficient structural strength when pressing the touch panel. The technical solution of the utility model optimizes the structure of the touch panel, not only effectively improves the structural strength of the touch panel, but also effectively reduces the tolerance between the structures to improve the stability of the structure.
