[0039] The circuit board 200 may be a plate-like structure, with one side facing the touch panel 100 and the other side facing away from the touch panel 100. One side of the circuit board 200 may be attached to the touch panel 100, and the other side of the circuit board 200 may include a vibrator 210. In one embodiment, the circuit board 200 may have a generally similar outer contour to the touch panel 100, such as a rectangular or rounded rectangular outer contour. In one embodiment, the vibrator 210 may be located at the center of the outer contour of the touch panel 100, for example, at the intersection of the diagonals of the rectangular contour. The vibrator 210 may be generally parallel to the second edge 102 of the touch panel 100. In one embodiment, the vibrator 210 may be a linear motor. The connection between the touch panel 100 and the circuit board 200 may be achieved by one of the following: adhesive, double-sided tape, epoxy resin, or a combination thereof. In one embodiment, the vibrator 210 may have a generally rectangular shape.

[0040] The bracket 300 can be positioned on the other side of the circuit board 200, or the circuit board 200 can be positioned between the touch panel 100 and the bracket 300. The bracket 300 may include: a body 310, a through hole 320, a plurality of first arms 330, a plurality of second arms 340, an inner frame 350, a plurality of third arms 360, and one or more mounting portions 370, etc. In one embodiment, the bracket 300 may include at least: a body 310, a through hole 320, a plurality of first arms 330, etc. In another embodiment, the bracket 300 may include at least: a body 310, a through hole 320, a plurality of first arms 330, an inner frame 350, and a plurality of third arms 360, etc.

[0041] The body 310 may constitute the main part of the bracket 300 and may extend along the outer contour of the touch panel 100. In one embodiment, the outer contour of the body 310 may correspond substantially to the outer contour of the touch panel 100 and / or the circuit board 200. In one embodiment, the body 310 may extend around the vibrator 210. In one embodiment, a plurality of second arms 340 and one or more mounting portions 370 may be located at the outer contour of the body 310.

[0042] The through-hole 320 can be located inside the body 310 and can extend through the body 310. In the illustrated embodiment, the circuit board 200 and the vibrator 210 are visible through the through-hole 320. In one embodiment, the vibrator 210 can be positioned within the through-hole 320, or in other words, the vibrator 210 is accessible through the through-hole 320. In one embodiment, a plurality of first arms 330, an inner frame 350, and a plurality of third arms 360 can be located within the through-hole 320. The outer contour of the through-hole 320 can correspond to the inner contour of the body 310. The outer contour of the through-hole 320 can have an irregular shape, such as... Figure 1 As shown in the image.

[0043] Multiple first arms 330 may extend from the body 310, for example, from the inner contour of the body 310, and extend into the interior of the through-hole 320. In one embodiment, the first arms 330 may extend in a straight line, and a first connecting portion 331 may be formed on the first arm 330. Figure 1 In the illustrated embodiment, the first connecting portion 331 may be elongated, and the width of the extension between the first connecting portion 331 and the body 310 may be smaller than the width of the first connecting portion 331. The width dimension mentioned above refers to the dimension in the direction perpendicular to the extension direction of the first arm 330. The first connecting portion 331 may be attached to the circuit board 200, and the attachment connection may be achieved by one of the following: adhesive, double-sided adhesive, epoxy resin, or a combination thereof. In one embodiment, the attachment connection between the first connecting portion 331 and the circuit board 200 is cured by ultraviolet light.

[0044] Furthermore, the first arm 330 may extend substantially parallel to the first edge 101 of the rectangular outline of the touch panel 100. In one embodiment, the support 300 may include four first arms 330. Each first arm 330 originates from a point near the center of the rectangular outline of the touch panel 100 and is symmetrically arranged on both sides of the axis of symmetry of the rectangular outline of the touch panel 100. Figure 1 In the illustrated embodiment, each first arm 330 extends toward the second edge 102. Two first arms 330 may be arranged on each side of the vibrator 210, and the four first arms 330 may form a symmetrical shape on both sides of the vibrator 210. The first arms 330 may be parallel to each other and extend in a direction away from the vibrator 210. In one embodiment, the first connecting portion 331 of the first arm 330 may be attached to the circuit board 200 at a symmetrical position around the vibrator 210. The first connecting portion 331 of each first connecting arm 330 may be positioned near the corners of the rectangular outline of the touch panel 100.

[0045] Multiple second arms 340 may be arranged along the outer contour of the body 310. In one embodiment, one end of the second arm 340 may extend from the body 310 and include a second connecting portion 341. The second connecting portion 341 may be attached to the circuit board 200 near the outer contour of the touch panel 100. The attachment may be achieved by one of the following: adhesive, double-sided adhesive, epoxy resin, or a combination thereof. The second arm 340 may have a structure similar to that of the first arm 330, for example, having a wider second connecting portion 341 and a narrower extension. In the illustrated embodiment, the second arm 340 may extend generally parallel to the first edge 101 of the rectangular outer contour of the touch panel 100, and each second arm 340 may be arranged adjacent to a particular first arm 330. Hereinafter, such adjacently arranged first arms 330 and second arms 340 are referred to as an arm combination. For example, Figure 1 The first arm 330 and the second arm 340, located in the lower left corner of the diagram, can be referred to as an arm assembly. This is easily understood. Figure 1 The embodiment includes four arm assemblies, located at the lower left, upper left, upper right, and lower right positions of the rectangular outline of the touch panel 100. In each arm assembly, the first arm 330 and the second arm 340 can be arranged to be substantially parallel to each other and extend in opposite directions. Furthermore, the first connecting portion 331 and the second connecting portion 341 can be spaced apart. In fact, in Figure 1In one embodiment, the first connecting portions 331 of the two first arms 330 on the left are located near the second edge 102 on the left, and the line connecting the first connecting portions 331 of the two first arms 330 can be parallel to the second edge 102. Similarly, the line connecting the second connecting portions 341 of the two second arms 340 on the left can also be parallel to the second edge 102 and spaced parallel to the line connecting the first connecting portions 331 of the two first arms 330. In one embodiment, the number of first arms 330 and second arms 340 can be equal.

[0046] The inner frame 350 may be located inside the through-hole 320 and spaced apart from the body 310. In one embodiment, the inner frame 350 may extend around the vibrator 210 and may be attached to the circuit board 200. The attachment may be achieved using adhesive, double-sided tape, epoxy resin, or a combination thereof. In one embodiment, the inner frame 350 may be annular or rectangular. In one embodiment, the outer contour of the inner frame 350 and the outer contour of the touch panel 100 may have similar shapes, such as both being rectangular. In one embodiment, a plurality of first arms 330 may extend along an extension of one edge of the rectangular contour of the inner frame 350, and the first arms 330 may extend from the body 310 near the rectangular contour of the inner frame 350 and extend in a direction away from the inner frame 350, such that a first connection 331 is positioned away from the inner frame 350. In one embodiment, a second connection 341 of a second arm 340 may be positioned near an extension of another edge of the rectangular contour of the frame 350. In one embodiment, the edges of the rectangular outline of the inner frame 350 and their extensions can divide the outer outline of the touch panel 100 into nine parts that are approximately equal in size, each part having approximately equal area. By adopting the technical solution of this application, when a user's finger clicks and moves on the touch panel 100, the displacement of each part on the touch panel 100 in the plane of the touch panel 100 is minimized through the coordinated action of the first arm 330, the second arm 340, the third arm 360, and the inner frame 350.

[0047] Multiple third arms 360 can be connected between the inner frame 350 and the body 310. In one embodiment, the third arms 360 can be arranged symmetrically on both sides of the vibrator 210 to form an axisymmetric arrangement. In one embodiment, the third arms 360 can extend along an axis of symmetry of the rectangular outline of the touch panel 100, or as... Figure 1As shown, the horizontal axes of symmetry A2-A2 of the rectangular outline of the touch panel 100 are spaced parallel to each other to allow space for electrical components on the circuit board 200. In one embodiment, each third arm 360 may be spaced parallel to each first arm 330 and / or each second arm 340. The above axes of symmetry are... Figure 1 It is shown schematically with a dashed line.

[0048] In addition, such as Figure 1 As shown, the plurality of first arms 330, the plurality of second arms 340, the inner frame 350, and the plurality of third arms 360 may be symmetrically arranged on both sides of the vertical axis of symmetry A1-A1 of the rectangular outer contour of the touch panel 100. Simultaneously, the plurality of first arms 330, the plurality of second arms 340, and the inner frame 350 may also be symmetrically arranged on both sides of the horizontal axis of symmetry A2-A2 of the rectangular outer contour of the touch panel 100.

[0049] There may be one or more mounting portions 370, which are arranged around the outer contour or periphery of the bracket 300. The mounting portion 370 may be a mounting hole or a half-hole structure, and extends beyond the outer contour of the touch panel 100 and / or the circuit board 200. In one embodiment, the mounting portion 370 may mount the touch panel assembly 10 by means of snap-fit, bolt connection and / or screw connection.

[0050] The bracket 300 may be a one-piece molded component, for example, made from one of the following materials by stamping and / or cutting processes: stainless steel, aluminum-magnesium alloy, tin-plated steel sheet, galvanized steel sheet, or combinations thereof. In one embodiment, the bracket 300 may be plate-shaped.

[0051] This application also relates to an electronic device including a housing and a touchpad assembly 10 described above. The housing may include an opening, and the touchpad assembly 10 may be mounted inside the housing. For example, a bracket 300 may be attached to other components that can be attached to the housing or the interior of the housing, such that the touchpad 100 is positioned at the opening in the housing. In one embodiment, the electronic device may be a laptop computer. In one embodiment, the housing may be a C-shell of a laptop computer.

[0052] The touchpad assembly and electronic device of this application have the advantages of being simple, reliable, easy to implement, and convenient to use, and can provide an improved touch operation and force feedback experience.
