This invention provides a method and system for adjusting the sensitivity of a mobile terminal's touchscreen, comprising the following steps: collecting the average pressure value corresponding to a user's touch operation within a preset time period; determining the touchscreen sensitivity corresponding to the average pressure value; detecting whether the touchscreen sensitivity corresponding to the average pressure value is greater than a fixed sensitivity value; and when the touchscreen sensitivity corresponding to the average pressure value is greater than the fixed sensitivity value, reducing the fixed sensitivity value.

[0029] The present invention will be further explained below with reference to specific embodiments.

[0030] Example

[0031] refer to Figures 1-6 This embodiment proposes a method to improve the sensing sensitivity of large-size capacitive touchscreens, including the following steps:

[0032] S1: When the capacitive screen 1 detects that an object is touching the capacitive screen 1, the touch sensing unit inside the capacitive screen 1 receives the information.

[0033] S2: The information received by the touch sensing unit includes touch pressure and touch coordinates;

[0034] S3: The touch sensing unit sends the touch information to the touch screen controller;

[0035] S4: The touch screen controller sends information to the main board controller. After receiving the information, the main board controller processes it and starts the cooling and dehumidification equipment to operate.

[0036] The cooling and dehumidifying device in S4 includes a housing 3 fixedly installed on the right side of the capacitive touchscreen 1. A partition 4 is integrally machined on the left side of the interior of the housing 3, isolating the internal space of the housing 3. The left side of the housing 3 has an opening structure, and the right side of the capacitive touchscreen 1 connects to this opening. The partition 4 is located on the right side of the capacitive touchscreen 1. The opening structure on the left side of the housing 3 facilitates the absorption of heat from the capacitive touchscreen 1 by the air inside the housing 3, ensuring timely heat dissipation and maintaining the sensing sensitivity of the capacitive touchscreen 1. The partition 4 divides the housing 3 into two cavities: the left cavity for heat absorption and the right cavity for air exhaust. A motor 5 is fixedly installed on the right side of the housing 3. The output end of the motor 5 passes through a hole on the right side of the interior of the housing 3 and is fixedly fitted with a transmission wheel 6. The motor 5 can... The transmission belt 7 is connected to the surface of the transmission belt 6 to drive the transmission wheel 6 to rotate. Guide wheels 8 are slidably connected to the top and bottom of the transmission belt 7. The transmission wheel 6 drives the transmission belt 7 to rotate, and the guide wheels 8 guide the transmission belt 7. The transmission belt 7 has an L-shaped structure and is connected to the guide wheels 8, which are located behind the transmission wheel 6. The axis of the guide wheels 8 is rotatably connected to the interior of the outer casing 3. The structure of the guide wheels 8 and the transmission belt 7 allows the interior of the transmission belt 7 to connect to both the transmission wheel 6 and the connecting wheel 9, enabling the transmission wheel 6 to drive the connecting wheel 9 to rotate via the transmission belt 7. The position of the guide wheels 8 and the transmission wheel 6 prevents collisions between the transmission wheel 6 and the guide wheels 8 during rotation, ensuring smooth transmission. The left side of the transmission belt 7 is connected to... A connecting wheel 9 has a roller 10 rotatably connected to its top surface. A transmission frame 11 is slidably connected to the surface of the roller 10. The transmission belt 7 can drive the connecting wheel 9 to rotate, and the connecting wheel 9 can drive the roller 10 to reciprocate up and down. The roller 10 slides inside the elongated ring of the transmission frame 11 and drives the transmission frame 11 to move up and down. The axis of the connecting wheel 9 is rotatably connected to the inside of the outer casing 3. The middle part of the transmission frame 11 is an elongated ring structure, and the roller 10 is located inside the elongated ring of the transmission frame 11. During the rotation of the connecting wheel 9, the roller 10 moves up and down. During the rotation of the roller 10, it slides left and right inside the elongated ring of the transmission frame 11 and drives the transmission frame 11 to move up and down. The rotation of the roller 10 can reduce the distance between the connecting wheel 9 and the transmission frame 11. Friction enhances the smoothness of structural transmission. A sliding sleeve 12 is slidably connected to the surface of the transmission frame 11. The rear side of the sliding sleeve 12 is bolted to the interior of the outer shell 3. The sliding sleeve 12 can slide and limit the transmission frame 11.

Adjusting wheels 13 are engaged at the bottom of both sides of the transmission frame 11. A transmission rod 14 is welded to the surface of the adjusting wheel 13, and a hinge rod 15 is hinged to the bottom end of the transmission rod 14. The transmission frame 11 can drive the two adjusting wheels 13 to rotate, which in turn drives the transmission rod 14 to rotate, and the transmission rod 14 drives the hinge rod 15 to rotate.

The bottom end of the rear side of the transmission rod 14 is connected to the top end of the hinge rod 15. The transmission rod 14 and hinge rod 15 connected to the left adjusting wheel 13 are located behind the transmission rod 14 and hinge rod 15 connected to the right adjusting wheel 13. This prevents the two transmission rods 14 from colliding, the two hinge rods 15 from colliding, or the transmission rod 14 from colliding with the hinge rod 15 during the rotation of the hinge rod 15 via the transmission rod 14. This ensures smooth transmission of the structure and allows the transmission rod 14 to drive the stopper 16 to move up and down via the hinge rod 15. The inside of the outer shell 3 is provided with a stopper 16 that is hinged to the two hinge rods 15. During the rotation of the hinge rod 15, it first drives the stopper 16 downward and then upward. The left side of the plug 16 is slidably connected to the right side of the partition 4. The right, front, and rear sides of the plug 16 are all slidably connected to the interior of the outer shell 3. The plug 16 is slidably set with the partition 4 via a slide rail, allowing the plug 16 to move smoothly up and down. The interior of the plug 16 is a hollow structure, and the hollow structure of the plug 16 is connected to the air hole 17. When the plug 16 moves upward, the air squeezes the flexible plate 18 downward, causing the flexible plate 18 to seal the air hole 17, facilitating the upward movement of the plug 16 with air. An air hole 17 is provided at the bottom of the plug 16, and a flexible plate 18 is bolted to the inside of the plug 16 and at the top of the air hole 17. When the plug 16 moves downward, air pushes up the flexible plate 18 through the air hole 17, allowing air to enter the plug 16. The top cavity of the 6th floor allows the soft plate 18 to be squeezed and fit against the air hole 17 when the plug 16 moves upward, allowing the plug 16 to drive air upward. A small gear 19 is meshed on the top right side of the transmission frame 11, allowing the transmission frame 11 to drive the small gear 19 to rotate. A transmission disc 20 is welded to the rear side of the small gear 19, allowing the small gear 19 to drive the transmission disc 20 to rotate. The axis of the transmission disc 20 is rotatably connected to the interior of the outer casing 3. A drying mechanism 2 is meshed on the left side of the transmission disc 20, with its bottom bolted to the top of the outer casing 3.

Both ends of the stirring rod 205 are rotatably sleeved with the interior of the drying box 206. There are four vent plates 207, and the top and bottom sides of the drying box 206 are respectively bonded to the sides of the four vent plates 207. The desiccant 208 is stored inside the drying box 206. The cavity, with stirring rod 205 agitating the desiccant 208 inside the drying box 206, fills the cavity with air gaps, allowing air to enter the cavity on the right side of the drying box 206 through the vent plate 207 on the bottom right side. The desiccant 208 dries the air. The bottom of the drying box 206 is bolted to the top of the outer shell 3, and the cavity of the drying box 206 is connected to the interior of the outer shell 3. The transmission disc 20 drives the rotating rod 202 to rotate via the rotating wheel 201. The rotating rod 202 drives the driven wheel 204 to rotate via the driving wheel 203. The driven wheel 204, via stirring rod 205, agitates the desiccant 208 inside the drying box 206, facilitating air passage. The desiccant 208 can then be agitated by the stirring rod 205. The air is dried and filtered to prevent moisture from accumulating inside the outer casing 3, ensuring the sensing sensitivity of the capacitive screen 1. The drying box 206 has three cavities, with two portions of desiccant 208 stored in the cavities on either side of the drying box 206. The driving wheel 203 and the driven wheel 204 are both located in the cavity in the middle of the drying box 206. The cavity on the left side of the drying box 206 communicates with the cavity on the left side of the outer casing 3, and the cavity on the right side of the drying box 206 communicates with the cavity on the right side of the outer casing 3. Air enters the cavity on the left side of the outer casing 3 from the cavity on the left side of the drying box 206, flows downwards, passes through the hole at the bottom of the partition 4, enters the cavity on the right side of the outer casing 3, and finally exits through the cavity on the right side of the drying box 206.

[0037] Working principle: When the power supply to motor 5 is turned on, motor 5 drives transmission wheel 6 to rotate, transmission wheel 6 drives transmission belt 7 to rotate, guide wheel 8 guides transmission belt 7, allowing transmission belt 7 to drive connecting wheel 9 to rotate, connecting wheel 9 drives roller 10 to reciprocate up and down, roller 10 slides inside the elongated ring of transmission frame 11 and drives transmission frame 11 to move up and down, sliding sleeve 12 can limit the sliding of transmission frame 11, when transmission frame 11 moves down, transmission frame 11 can drive two adjusting wheels. When the adjusting wheel 13 rotates, it drives the transmission rod 14 to rotate, which in turn drives the hinge rod 15 to rotate. During rotation, the hinge rod 15 first moves the stopper 16 downwards, then upwards. As the stopper 16 moves downwards, air passes through the vent 17, pushing up the flexible plate 18 and allowing air to enter the cavity at the top of the stopper 16. When the stopper 16 moves upwards, the flexible plate 18 is compressed and pressed against the vent 17, allowing the stopper 16 to move the air upwards, thus allowing the air to escape from the right side of the drying box 206. The transmission frame 11 drives the pinion 19 to rotate, which in turn drives the transmission disc 20 to rotate. The transmission disc 20 then drives the rotating wheel 201 to rotate, which in turn drives the rotating rod 202 to rotate. The rotating rod 202 drives the driving wheel 203 to rotate, which in turn drives the driven wheel 204 to rotate. The driven wheel 204 then drives the stirring rod 205 to rotate, which in turn stirs the desiccant 208 inside the drying box 206, filling the gaps inside the desiccant 208. Air enters the cavity on the right side of the drying box 206 through the vent plate 207 on the bottom right side of the drying box 206. The desiccant 208 dries the air, and then it is discharged through the vent plate 207 on the top right side of the drying box 206. After the air is discharged, a negative pressure is formed inside the outer shell 3, allowing outside air to enter the desiccant 208 on the left side of the drying box 206 through the vent plate 207, and finally enter the cavity on the left side of the partition 4 to absorb the heat of the capacitive screen 1. This process is repeated so that air can continuously enter and exit the outer shell 3.
