Description

Technical Field

[0001] The utility model relates to the technical field of touch control, in particular to a touch control panel for a computer. Background Art

[0002] A touchpad is an input device widely used in electronic products. It uses the movement of a user's finger to control the movement of a pointer and selects or operates a target by pressing the user's finger.

[0003] The touchpads in the prior art are divided into mechanical touchpads and capacitive touchpads. Mechanical touchpads can usually only be pressed on one side, and then the pressed side of the touchpad moves to select or operate the target. Although this type of touchpad is low-cost, it will move downward on one side when pressed on one side, resulting in a poor feel. Capacitive touchpads can receive press signals at any position on the touchpad, and have a better feel, but because the received signal is an electrical signal, a sensor is required on the entire touchpad surface, and the cost is relatively high.

[0004] How to improve the touchpad feel while taking into account the cost of the touchpad is a technical problem that needs to be solved urgently in the industry. Utility Model Content

[0005] The utility model aims to provide a computer touch panel, which can improve the hand feeling of the touch panel on the one hand and reduce the cost required for improving the hand feeling on the other hand.

[0006] The utility model provides a computer touch panel, comprising:

[0007] A fixed bracket, the fixed bracket comprising a bracket outer frame, and a bracket platform disposed inside the bracket outer frame and protruding upward, wherein the bracket outer frame and the bracket platform are connected by an elastic support strip;

[0008] A touch panel PCB, wherein the touch panel PCB is arranged above the bracket, and a middle portion of the touch panel PCB is supported by the bracket platform;

[0009] A plurality of first touch switches, wherein the plurality of first touch switches are arranged between the bracket outer frame of the fixed bracket and the touch panel PCB;

[0010] A touch panel is arranged on the upper surface of the touch panel PCB.

[0011] Furthermore, the number of the first touch switches is four, which are respectively arranged at corresponding positions of the four corners of the touch panel PCB.

[0012] Further, the computer touchpad further includes a second tactile switch. The middle part of the bracket platform is hollowed out, and a support block is provided in the hollowed-out area. The second tactile switch is arranged between the support block and the touchpad PCB.

[0013] Further, the fixing bracket further includes fixing edges arranged on both sides, and connection holes are formed in the fixing edges.

[0014] Optionally, the number of the first tactile switches is 4, and they are respectively arranged at corresponding positions in the middle of each side of the bracket outer frame.

[0015] Optionally, the computer touchpad further includes a second tactile switch. A receiving groove is formed by the middle part of the bracket platform sinking downward. The bottom surface of the receiving groove is flush with the upper surface of the bracket outer frame, and the second tactile switch is arranged in the receiving groove.

[0016] Further, the contact position between the bracket platform and the touchpad PCB is bonded by double-sided tape.

[0017] Further, the touch panel is a glass panel.

[0018] Further, the elastic support strips include four first elastic support strips. One end of each first elastic support strip is fixed at the vertex of the bracket outer frame, and the other end is fixed to the bracket platform.

[0019] Further, the elastic support strips further include more than four second elastic support strips. One end of each second elastic support strip is fixed on the edge of the bracket outer frame, and the other end is fixed to the bracket platform.

[0020] The technical effect of this technical solution is that in the present utility model, the fixing bracket is divided into a bracket outer frame and a bracket platform. The bracket platform bulges upward to carry the touchpad PCB. In this way, a state where the middle part of the touchpad PCB is fixed and the periphery is suspended can be formed. It is convenient to set tactile switches at these suspended positions, that is, the tactile switches are arranged between the edge part of the touchpad PCB and the upper surface of the support outer frame. Since the middle part of the support plate is supported, when the user presses the touchpad, there will be no obvious displacement on the pressing side of the touchpad. And because a plurality of first tactile switches are arranged below the suspended part of the touchpad, the slight displacement generated by pressing can be recognized by the first tactile switches, thereby completing the selection or operation of the target. Through this structural design method, on the one hand, the feel of the touchpad is improved, and on the other hand, the cost required to improve the feel is taken into account.
