[0015] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0016] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0017] Reference Figure 1-2The utility model provides a five-point touch full-domain touchpad module, including a touchpad glass 1, a touchpad PCBA2 and a fixed base plate 5, characterized in that the touchpad glass 1 is bonded to one side of the touchpad PCBA2; a metal spring 4 is provided between the touchpad PCBA2 and the fixed base plate 5; the metal spring 4 is provided with a backing glue 3 and bonded to the other side of the touchpad PCBA2, and the metal spring 4 is provided with a machine screw 6 for controlling the deformation amount of the metal spring 4; the backing glue adopts 3M backing glue, and the user moves the finger on the touchpad glass 1, and cooperates with the touchpad PCBA2 to control the movement of the pointer.

[0018] As a further preferred solution of the present invention, the metal spring sheet 4 is connected to the fixed base plate 5 by screws to fix the touch panel module and strengthen the structure.

[0019] As a further preferred embodiment of the present invention, the metal shrapnel 4 is in an "H" shape, wide on both sides and narrow in the middle, and is spot-welded to an outer frame. The adhesive 3 is installed on the outer frame, and the machine screw 6 is installed in the middle of the metal shrapnel 4. The metal shrapnel 4 is tightened by the machine screw 6. The machine screw 6 cooperates with the metal shrapnel 4 to adjust the screw height, thereby adjusting the pre-compression amount of the pot piece of the touch panel PCBA3 to improve the feel of the touch panel module.

[0020] As a further preferred solution of the present invention, the metal spring piece 4 is a stainless steel spring piece.

[0021] As a further preferred embodiment of the present invention, a pot is installed on the touchpad PCBA2, and the pot is provided with buttons and is pasted on the metal spring sheet 4 through double-sided adhesive. After pressing the touchpad glass 1, the pot contacts the screw below to realize the pressing function. After releasing the hand, the stainless steel metal spring sheet 4 provides elastic force to restore the touchpad module to its original state. The machine screws 6 adjust the feel of the touchpad module, and the fixed base plate 5 is used to strengthen the structure of the touchpad module and optimize the feel.

[0022] When the touch panel glass 1 is pressed, the metal spring 4 undergoes elastic deformation, causing the moving part to move along the pressing direction, contacting the pot on the touch panel PCBA 2 and triggering the travel switch. Then it rebounds, and the four elastic arms on the metal spring 4 are just distributed in the four directions of the touch panel glass 1. The spring range covers the entire touch panel glass 1, so that the entire touch panel glass 1 can achieve full-range pressing control.
