[0030] Please refer to Figures 1 to 5 , the floating touchpad structure 100 of the present utility model includes a touchpad body 1, a touchpad bracket 2, a first magnetic member 3 and a second magnetic member 4. One side of the touchpad body 1 is pivotally connected to one side of the touchpad bracket 2. The first magnetic member 3 is disposed on the touchpad body 1, and the second magnetic member 4 is disposed on the touchpad bracket 2, and the first magnetic member 3 and the second magnetic member 4 are arranged relatively and magnetically repellent to make the touchpad body 1 float relative to the touchpad bracket 2. Among them, the pivotal connection mode between one side of the touchpad body 1 and one side of the touchpad bracket 2 can adopt an existing hinge structure or can directly use a rotating shaft for connection, but not limited thereto. Also, the N pole of the first magnetic member 3 is facing the N pole of the second magnetic member 4, and the S pole of the first magnetic member 3 is facing the S pole of the second magnetic member 4, so as to realize the magnetic repulsion between the first magnetic member 3 and the second magnetic member 4.
[0031] The floating touchpad structure 100 of the present utility model makes the touchpad body 1 float relative to the touchpad bracket 2 within a certain range by arranging a first magnetic member 3 on the touchpad body 1 and a second magnetic member 4 on the touchpad bracket 2, and utilizing the repulsive magnetic force between the first magnetic member 3 and the second magnetic member 4, thereby supporting the touchpad body 1 by magnetic force, reducing the contact friction between the touchpad body 1 and the touchpad bracket 2, and making the rotation of the touchpad body 1 relative to the touchpad bracket 2 smoother.
[0032] Please refer to Figure 5 and Figure 6 , in an embodiment, the first magnetic member 3 is arranged on the other side of the touchpad body 1, and the second magnetic member 4 is arranged on the other side of the touchpad bracket 2. By pivotally connecting one side of the touchpad body 1 to one side of the touchpad bracket 2, and arranging the first magnetic member 3 and the second magnetic member 4 on the other sides of the touchpad body 1 and the touchpad bracket 2 respectively, sufficient rotation stroke of the touchpad body 1 relative to the touchpad bracket 2 is ensured.
[0033] Please refer to Figure 2 and Figure 3 , in an embodiment, the first magnetic member 3 is fixed on the bottom surface of the touchpad body 1 facing the touchpad bracket 2, and the second magnetic member 4 is fixed on the top surface of the touchpad bracket 2 facing the touchpad body 1.
[0034] Please refer to Figure 2 and Figure 3 , in an embodiment, a plurality of first magnetic members 3 are arranged on the touchpad body 1 at intervals along the same straight line direction, and a plurality of second magnetic members 4 are arranged on the touchpad bracket 2 corresponding to the first magnetic members 3 one by one. Thus, the touchpad body 1 and the touchpad bracket 2 are supported in a floating manner at multiple positions by the first magnetic member 3 and the second magnetic member 4, ensuring the operation balance when clicking or pressing the touchpad body 1.
[0035] Please refer to Figures 2 to 6, in one embodiment, the floating touchpad structure 100 of the present utility model further includes a limiting mechanism 5. The limiting mechanism 5 is disposed between the touchpad body 1 and the touchpad bracket 2, and the limiting mechanism 5 is used to limit the rotation stroke of the touchpad body 1 relative to the touchpad bracket 2. By providing the limiting mechanism 5, the rotation stroke of the touchpad body 1 relative to the touchpad bracket 2 can be limited, thereby avoiding an excessive rotation stroke of the touchpad body 1 relative to the touchpad bracket 2. Specifically, the limiting mechanism 5 includes a limiting bracket 51 and a limiting buckle 52. The limiting bracket 51 is disposed on the touchpad body 1, and a limiting slot 511 is provided on the limiting bracket 51. The limiting buckle 52 is disposed on the touchpad bracket 2, and the limiting buckle 52 is movably engaged in the limiting slot 511. When the touchpad body 1 is clicked or pressed, the touchpad body 1 drives the limiting bracket 51 to rotate and move downward, and the limiting buckle 52 limits the downward movement position of the limiting bracket 51 through the limiting slot 511, avoiding an excessive downward movement stroke of the touchpad body 1 during rotation. More specifically, the touchpad bracket 2 has a bent portion 21 that bends away from the touchpad body 1, and the limiting buckle 52 is disposed on the bent portion 21.
[0036] Please refer to Figure 2 and Figure 3 , in one embodiment, the floating touchpad structure 100 of the present utility model further includes a Hall sensor 6 and a third magnetic member 7.

By providing the Hall sensor 6 and the third magnetic member 7, when the touchpad body 1 is clicked or pressed, the touchpad body 1 will drive one of the Hall sensor 6 and the third magnetic member 7 to move, causing a change in the distance between the Hall sensor 6 and the third magnetic member 7, thereby using the Hall principle to confirm the touch displacement. Specifically, a plurality of Hall sensors 6 are disposed on the touchpad body 1, and a plurality of third magnetic members 7 are arranged on the touchpad bracket 2 in one-to-one correspondence with the Hall sensors 6. More specifically, the Hall sensor 6 and the third magnetic member 7 are disposed at positions adjacent to the first magnetic member 3 and the second magnetic member 4.
[0037] Please refer to Figure 7 and Figure 8, in another embodiment, the floating touchpad structure 100 of the present utility model further includes a dome sheet 8 and a PCB component 9. One of the dome sheet 8 and the PCB component 9 is disposed on the touchpad body 1, and the other of the dome sheet 8 and the PCB component 9 is disposed on the touchpad bracket 2, and the dome sheet 8 and the PCB component 9 are arranged opposite to each other. Among them, the dome sheet 8 and the PCB component 9 are disposed at the left and right button positions corresponding to the touchpad body 1. By clicking or pressing the button of the touchpad body 11, one of the dome sheet 8 and the PCB component 9 is driven to move towards the other, so that the dome sheet 8 contacts the PCB component 9 and signal transmission is achieved. Specifically, in this embodiment, the dome sheet 8 is disposed on the touchpad body 1, and the PCB component 9 is disposed on the touchpad bracket 2, but not limited thereto. More specifically, two groups of dome sheets 8 and PCB components 9 are respectively arranged at the left and right positions of the touchpad body 1 and the touchpad bracket 2.
[0038] In summary, the floating touchpad structure 100 of the present utility model realizes magnetic levitation support for the touchpad body 1 by arranging a first magnetic member 3 on the touchpad body 1 and a second magnetic member 4 on the touchpad bracket 2, and using the repulsive magnetic force between the first magnetic member 3 and the second magnetic member 4. This reduces the contact friction between the touchpad body 1 and the touchpad bracket 2, makes the rotation of the touchpad body 1 relative to the touchpad bracket 2 smoother, improves the consistency of the touch and press feel, reduces or eliminates the noise generated when clicking the touchpad body 1, provides a quieter use environment, and provides a more delicate and natural touch experience. And the magnetic levitation support technology allows the touchpad body 1 to be designed thinner, which conforms to the trend of modern electronic products pursuing thinness and lightness, and helps the overall compact design of the device. Using magnetic levitation to support the touchpad body 1 can also achieve adjustable touch feedback, which can be set according to personal preferences by users, increasing the personalization of use. At the same time, due to the reduction of the contact friction between the touchpad body 1 and the touchpad bracket 2, the service life of the touchpad body 1 can be extended, and the durability of the entire structure can be improved. Moreover, the floating touchpad structure 100 of the present utility model can capture the movement of the finger more accurately by arranging a Hall sensor 6 and a third magnetic member 7, improving the accuracy and response speed of touch, which is particularly important for application scenarios that require fine operations.
