[0031] Example 1

[0032] See also Figure 1The present invention provides a touchpad device in an embodiment. The touchpad device includes a track detection mechanism 1 and a deformation detection mechanism 2; the deformation detection mechanism 2 includes a deformation monitoring module 21, an elastic mechanism 22, and a plurality of support mechanisms 23. The plurality of support mechanisms 23 surround the elastic mechanism 22. The elastic mechanism 22 and the support mechanism 23 are respectively arranged on the same side of the track detection mechanism 1. The deformation monitoring module 21 is connected to the elastic mechanism 22 and the track detection mechanism 1 respectively. The specific description of each component is as follows:

[0033] In this embodiment, the trajectory detection mechanism 1 includes a touchpad that has the function of obtaining position information of a finger on the surface of the trajectory detection mechanism 1. When a finger slides on the trajectory detection mechanism 1, the trajectory detection mechanism 1 can obtain the trajectory of the finger's sliding in real time. The deformation detection mechanism 2 is used to monitor the deformation of the object to be measured. In this embodiment, the deformation monitoring module 21 is installed on the elastic mechanism 22 and has the function of monitoring the deformation of the elastic mechanism 22 in real time. The support mechanism 23 is used to support and drive the deformation of the elastic mechanism 22. Multiple support mechanisms 23 are distributed around the elastic mechanism 22. When the finger applies pressure on the trajectory detection mechanism 1, the trajectory detection mechanism 1 is displaced downward, causing the elastic mechanism 22 below the trajectory detection mechanism 1 to deform. The deformation obtained by the deformation monitoring module 21 and the position information of the finger obtained by the trajectory detection mechanism 1 are used to accurately calculate the pressure value applied by the finger on the touchpad according to a preset conversion formula (the same force applied at different positions of the trajectory detection mechanism 1 will produce corresponding deformation of the elastic mechanism 22, and the conversion formula can be determined through measurement).

[0034] Example 2

[0035] On the basis of Example 1, continue to refer to Figure 2-3 The present invention provides a touchpad device in an embodiment. The touchpad device includes a track detection mechanism 1 and a deformation detection mechanism 2; the deformation detection mechanism 2 includes a deformation monitoring module 21, an elastic mechanism 22, and a plurality of support mechanisms 23. The plurality of support mechanisms 23 surround the elastic mechanism 22. The elastic mechanism 22 and the support mechanism 23 are respectively arranged on the same side of the track detection mechanism 1. The deformation monitoring module 21 is connected to the elastic mechanism 22 and the track detection mechanism 1 respectively. The specific description of each component is as follows:

[0036] In this embodiment, the trajectory detection mechanism 1 includes a touchpad that has the function of obtaining position information of a finger on the surface of the trajectory detection mechanism 1. When a finger slides on the trajectory detection mechanism 1, the trajectory detection mechanism 1 can obtain the trajectory of the finger's sliding in real time. The deformation detection mechanism 2 is used to monitor the deformation of the object to be measured. In this embodiment, the deformation monitoring module 21 is installed on the elastic mechanism 22 and has the function of monitoring the deformation of the elastic mechanism 22 in real time. The support mechanism 23 is used to support and drive the deformation of the elastic mechanism 22. Multiple support mechanisms 23 are distributed around the elastic mechanism 22. When the finger applies pressure on the trajectory detection mechanism 1, the trajectory detection mechanism 1 is displaced downward, causing the elastic mechanism 22 below the trajectory detection mechanism 1 to deform. The deformation obtained by the deformation monitoring module 21 and the position information of the finger obtained by the trajectory detection mechanism 1 are used to accurately calculate the pressure value applied by the finger on the touchpad according to a preset conversion formula (the same force applied at different positions of the trajectory detection mechanism 1 will produce corresponding deformation of the elastic mechanism 22, and the conversion formula can be determined through measurement).

[0037] In this embodiment, a bracket 3 is further included, and the elastic mechanism 22 and the supporting mechanism 23 are respectively fixed on the bracket 3 .

[0038] Furthermore, the bracket 3 , the elastic mechanism 22 and the supporting mechanism 23 are integrally formed.

[0039] Specifically, the bracket 3 is provided with a plurality of holes, and the elastic mechanism 22 and the supporting mechanism 23 are respectively arranged in the holes. The bracket 3, the elastic mechanism 22 and the supporting mechanism 23 are integrally formed. In one embodiment, the elastic mechanism 22 is connected to the trajectory detection mechanism 1 through a soft material, and the supporting mechanism 23 is connected to the trajectory detection mechanism 1 through a soft material. The bracket 3 is made of metal material. A deformation monitoring module 21 for monitoring deformation is attached to the elastic mechanism 22. When the finger applies a certain pressure on the surface of the trajectory detection mechanism 1, the trajectory detection mechanism 1 will drive the bracket 3 to deform. For example: when the finger presses the corner of the trajectory detection mechanism 1, the trajectory detection mechanism 1 drives the bracket 3 to tilt. The deformation monitoring module 21 obtains the deformation amount of the elastic mechanism 22 and feeds it back to the trajectory detection mechanism 1. The trajectory detection mechanism 1 then calculates the accurate pressure value applied by the finger on the touchpad surface in combination with the coordinate information of the finger on the touchpad.

[0040] The support mechanism 23 is used to support and drive the elastic mechanism 22 to deform. The deformation of the elastic mechanism 22 is used as a parameter for detecting pressure. The touch panel device thus obtained presses any position on the surface of the track detection mechanism 1. Since the bracket 3, the elastic mechanism 22 and the support mechanism 23 are integrally formed, the lever effect generated simultaneously drives the elastic mechanism 22 to deform. However, the coordinate data of the finger is obtained through the track detection mechanism 1, and the pressure value applied by the finger on the touch panel surface can be determined by calculation, thereby reducing the production cost.

[0041] Furthermore, it further comprises a plurality of connecting members 5 , the elastic mechanism 22 is connected to the track detection mechanism 1 via the connecting members 5 , and the supporting mechanism 23 is connected to the track detection mechanism 1 via the connecting members 5 .

[0042] Specifically, the connector 5 is elastic and fits onto the elastic mechanism 22 and the support mechanism 23, respectively. The elastic mechanism 22 and the support mechanism 23 are connected to the track detection mechanism 1 via the connector 5. When the track detection mechanism 1 moves downward, the connector 5 acts as a buffer, preventing wear and tear caused by direct contact between the track detection mechanism 1 and the elastic mechanism 22 and the support mechanism 23. The connection via the connector 5 can improve the durability of the touchpad device.

[0043] Furthermore, the connecting member 5 is made of silicone material.

[0044] Specifically, the connecting member 5 is a silicone pad made of silicone material. The silicone material is low in cost and easy to obtain. The use of the silicone pad in the connecting member 5 can reduce the cost of the touch panel device.

[0045] Furthermore, the track detection mechanism 1 includes a PCB board 11 and a touch panel 12 , the PCB board 11 is fixed on the touch panel 12 , and the elastic mechanism 22 and the supporting mechanism 23 are respectively arranged on the same side of the PCB board 11 .

[0046] Specifically, the PCB, as the basic structure of electronic devices, carries various electronic components and provides electrical connections. In this embodiment, the PCB board 11 is fixed below the touch panel 12, and the PCB board 11 is provided with a sensor that can obtain the position information of the finger on the touch panel 12.

[0047] Furthermore, the deformation monitoring module 21 includes a strain sensor and an FPC board. The strain sensor is provided on the elastic mechanism 22 , and the FPC board is connected to the strain sensor and the PCB board 11 , respectively.

[0048] Specifically, an FPC board refers to a flexible printed circuit board that can be bent arbitrarily. In this embodiment, the FPC board and the strain sensor are respectively attached to the elastic mechanism 22. A strain sensor is a sensor that measures the strain generated by an object under force and deformation. It can convert changes in strain on a mechanical component into changes in resistance.

[0049] Example 3

[0050] On the basis of Example 1, continue to refer to Figure 4-8 The present invention provides a touchpad device in an embodiment. The touchpad device includes a track detection mechanism 1 and a deformation detection mechanism 2; the deformation detection mechanism 2 includes a deformation monitoring module 21, an elastic mechanism 22, and a plurality of support mechanisms 23. The plurality of support mechanisms 23 surround the elastic mechanism 22. The elastic mechanism 22 and the support mechanism 23 are respectively arranged on the same side of the track detection mechanism 1. The deformation monitoring module 21 is connected to the elastic mechanism 22 and the track detection mechanism 1 respectively. The specific description of each component is as follows:

[0051] In this embodiment, the trajectory detection mechanism 1 includes a touchpad that has the function of obtaining position information of a finger on the surface of the trajectory detection mechanism 1. When a finger slides on the trajectory detection mechanism 1, the trajectory detection mechanism 1 can obtain the trajectory of the finger's sliding in real time. The deformation detection mechanism 2 is used to monitor the deformation of the object to be measured. In this embodiment, the deformation monitoring module 21 is installed on the elastic mechanism 22 and has the function of monitoring the deformation of the elastic mechanism 22 in real time. The support mechanism 23 is used to support and drive the deformation of the elastic mechanism 22. Multiple support mechanisms 23 are distributed around the elastic mechanism 22. When the finger applies pressure on the trajectory detection mechanism 1, the trajectory detection mechanism 1 is displaced downward, causing the elastic mechanism 22 below the trajectory detection mechanism 1 to deform. The deformation obtained by the deformation monitoring module 21 and the position information of the finger obtained by the trajectory detection mechanism 1 are used to accurately calculate the pressure value applied by the finger on the touchpad according to a preset conversion formula (the same force applied at different positions of the trajectory detection mechanism 1 will produce corresponding deformation of the elastic mechanism 22, and the conversion formula can be determined through measurement).

[0052] In this embodiment, a base 4 is further included, and the trajectory detection mechanism 1 is connected to the base 4 through the deformation detection mechanism 2 .

[0055] Specifically, the first bridge-type bracket 2223 is made of a metal material and has an opening at its center. The first fixing column 221 includes a bolt that passes through the opening of the first bridge-type bracket 2223 and is fixed to the base 4. The first bridge-type bracket 2223 is in contact with the track detection mechanism 1. When the track detection mechanism 1 is displaced downward, the elastic mechanism 22 below the track detection mechanism 1 is deformed. The second bridge-type bracket 2323 is made of a metal material and has an opening at its center. The second fixing column 231 includes a bolt that passes through the opening of the second bridge-type bracket 2323 and is fixed to the base 4. The second bridge-type bracket 2323 is in contact with the track detection mechanism 1. When the track detection mechanism 1 is displaced downward, the support mechanism 23 supports the track detection mechanism 1 upward to prevent the track detection mechanism 1 from being displaced significantly downward.

[0056] In one embodiment, the trajectory detection mechanism 1 and the deformation detection mechanism 2 are embedded in the base 4 together, and the upper surface of the base 4 is at the same height as the upper surface of the trajectory detection mechanism 1 .

[0057] Furthermore, it further comprises a plurality of connecting members 5 , the elastic mechanism 22 is connected to the track detection mechanism 1 via the connecting members 5 , and the supporting mechanism 23 is connected to the track detection mechanism 1 via the connecting members 5 .

[0058] Specifically, the connector 5 is elastic and fits onto the elastic mechanism 22 and the support mechanism 23, respectively. The elastic mechanism 22 and the support mechanism 23 are connected to the track detection mechanism 1 via the connector 5. When the track detection mechanism 1 moves downward, the connector 5 acts as a buffer, preventing wear and tear caused by direct contact between the track detection mechanism 1 and the elastic mechanism 22 and the support mechanism 23. The connection via the connector 5 can improve the durability of the touchpad device.

[0059] Furthermore, the connecting member 5 is made of silicone material.

[0060] Specifically, the connecting member 5 is a silicone pad made of silicone material. The silicone material is low in cost and easy to obtain. The use of the silicone pad in the connecting member 5 can reduce the cost of the touch panel device.

[0061] Furthermore, the track detection mechanism 1 includes a PCB board 11 and a touch panel 12 , the PCB board 11 is fixed on the touch panel 12 , and the elastic mechanism 22 and the supporting mechanism 23 are respectively arranged on the same side of the PCB board 11 .

[0062] Specifically, the PCB, as the basic structure of electronic devices, carries various electronic components and provides electrical connections. In this embodiment, the PCB board 11 is fixed below the touch panel 12, and the PCB board 11 is provided with a sensor that can obtain the position information of the finger on the touch panel 12.

[0063] Furthermore, the deformation monitoring module 21 includes a strain sensor and an FPC board. The strain sensor is provided on the elastic mechanism 22 , and the FPC board is connected to the strain sensor and the PCB board 11 , respectively.

[0064] Specifically, an FPC board refers to a flexible printed circuit board that can be bent arbitrarily. In this embodiment, the FPC board and the strain sensor are respectively attached to the elastic mechanism 22.
