Description

Technical Field

[0001] The utility model relates to the technical field of touch panels, in particular to a touch panel with visualized pressing force. Background Art

[0002] A touchpad is an input device widely used on laptops. It controls the movement of the pointer by sensing the movement of the user's fingers and can be regarded as a substitute for a mouse. A capacitive touchpad uses capacitive sensing to detect finger movement. When a finger touches the board, the electrostatic field on the board changes. This change can be detected by the sensor, which converts the change into an electrical signal and transmits it to the processor for processing.

[0003] Existing touch panels are relatively easy to install. For example, Chinese patent application number CN202123261169.7 discloses a new touch panel, including a touch screen, a plastic middle frame and a fixed bottom plate. A balance bar is installed on the touch screen, and the touch screen is installed on the plastic middle frame. The plastic middle frame is detachably installed on the fixed bottom plate. Both ends of the touch screen are equipped with protrusions that protrude from the outer surface of the fixed bottom plate, and both ends of the fixed bottom plate are provided with positioning holes for easy installation.

[0004] This touchpad is used for the laptop computer by pressing the touch screen. When pressing the touch screen, the force generated by the pressure can only be felt by the fingers, and the pressure cannot be directly observed by the eyes. This makes it difficult to control the pressure, which can easily lead to excessive pressure and thus affect the service life of the touch screen. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a touch panel with visualized pressing force, which solves the problem that the pressing force on the touch panel cannot be directly observed.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a touch panel with visualized pressing force, comprising a bottom plate, the upper surface of the bottom plate is connected to a frame, one side of the upper surface of the bottom plate is connected to four side plates, a cylinder is rotatably connected between two corresponding side plates, the cylinder is made of a transparent acrylic plate material, one end of the cylinder is open, one of the side plates is connected to a fixing plate near the opening, the fixing plate extends into the inside of the cylinder, a light strip is connected to the upper surface of the fixing plate, the end of the cylinder near the frame passes through the side plate and is connected to a connecting rod, the outer surface of the connecting rod is connected to a coil spring, one end of the coil spring is connected to The bottom plate is connected, the end of the connecting rod away from the cylinder is connected to a turntable, both sides of the upper surface of the bottom plate are connected with spring sheets, the end of the spring sheet away from the cylinder is connected with a pull rope, this end of the spring sheet is slidably connected to the surface of the bottom plate, the other end of the pull rope is connected to the turntable and wound on the turntable, the surface of the cylinder is sprayed with a frosted layer, the thickness of the frosted layer continuously decreases in the clockwise direction of the axis of the cylinder, a control chip is installed on the upper surface of the bottom plate, a partition is connected to the upper surface of the bottom plate close to the cylinder, a touch panel is provided on the upper surface of the bottom plate, a sensor is provided on the touch panel, and the control chip is connected to the sensor and the light strip through a circuit.

[0007] Preferably, two limit frames are symmetrically connected to the upper surface of the bottom plate, and the end of the spring sheet away from the cylinder body passes through the corresponding limit frame.

[0008] Preferably, an annular groove is provided on one side of the side plate away from the coil spring, and one end of the corresponding cylinder extends into the annular groove.

[0009] Preferably, the outer surface of the spring sheet is covered with rubber.

[0010] Preferably, the frame and the partition are both connected with sealing sheets on one side facing each other.

[0011] Preferably, a through opening is formed through the outer surface of the side plate away from the coil spring.

[0012] Preferably, the inner width of the limiting frame is greater than the width of the spring sheet.

[0013] The utility model provides a touch panel with visualized pressing force, which has the following beneficial effects:

[0014] By setting structures such as the cylinder and the frosted layer, when the touch pad is pressed down, the spring sheet is squeezed by the touch pad, and one end of the spring sheet moves, thereby pulling the rope to rotate the cylinder. At this time, the frosted layer rotates, which reduces the light blocking effect of the frosted layer on the light strip, thereby allowing more light to pass through the cylinder and the frosted layer. According to the pressing or lifting of the touch screen, the cylinder and the frosted layer rotate counterclockwise or clockwise, thereby changing the light transmittance of the cylinder. Compared with the prior art, when the touch pad is pressed down, the cylinder and the frosted layer will rotate to corresponding angles according to the amplitude of the pressing, thereby changing the light transmittance of the cylinder. The greater the amplitude of the touch pad pressing down, the more light will pass through the cylinder, so that the pressing force on the touch pad can be visualized.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7The utility model provides a technical solution: a touch panel with visualized pressing force, comprising a bottom plate 1, a frame 2 is connected to the upper surface of the bottom plate 1, four side plates 3 are connected to one side of the upper surface of the bottom plate 1, a cylinder 4 is rotatably connected between two corresponding side plates 3, the cylinder 4 is made of a transparent acrylic plate, one end of the cylinder 4 is open, one of the side plates 3 is connected to a fixing plate 5 near the opening, the fixing plate 5 extends into the inside of the cylinder 4, a light strip 6 is connected to the upper surface of the fixing plate 5, an end of the cylinder 4 near the frame 2 passes through the side plate 3 and is connected to a connecting rod 7, a coil spring 8 is connected to the outer surface of the connecting rod 7, one end of the coil spring 8 is connected to the bottom plate 1, and the end of the connecting rod 7 away from the cylinder 4 is connected to a turntable 9, spring sheets 10 are connected to both sides of the upper surface of the bottom plate 1, and a pull rope 11 is connected to the end of the spring sheet 10 away from the cylinder 4, this end of the spring sheet 10 is slidably connected to the surface of the bottom plate 1, and the other end of the pull rope 11 It is connected to the turntable 9 and wound on the turntable 9, and a frosted layer 12 is sprayed on the surface of the cylinder 4, and the thickness of the frosted layer 12 continues to decrease in the clockwise direction of the axis of the cylinder 4. A control chip 13 is installed on the upper surface of the bottom plate 1, and a partition 14 is connected to the upper surface of the bottom plate 1 close to the cylinder 4. A touch panel 15 is provided on the upper surface of the bottom plate 1, and a sensor is provided on the touch panel 15. The control chip 13 is connected to the sensor and the light strip 6 through a line, and the cylinder 4 is located on one side of the partition 14, and the touch panel 15 is located on the other side of the partition 14. The connection method of the touch panel 15 and the bottom plate 1 is the existing technology. When the touch panel 15 is touched, the capacitance of the surface will change, and the change will be detected by the sensor and transmitted to the external processor for processing. This process is the existing technology and will not be repeated here. The control chip 13 can control the switch of the light strip 6, which is the existing technology, such as the FC703 model chip.

[0025] When working, the touch pad 15 is pressed and the sensor detects the change of the surface capacitance of the touch pad 15. The sensor converts the change into an electrical signal and transmits it to the control chip 13. The control chip 13 controls the light strip 6 to emit light. When the touch pad 15 is pressed down, the spring sheet 10 is squeezed, so that one end of the spring sheet 10 moves away from the cylinder 4, thereby pulling the pull rope 11. The pull rope 11 drives the turntable 9, the connecting rod 7, the cylinder 4, and the frosted layer 12 to rotate, and the coil spring 8 contracts. As the cylinder 4 rotates, the frosted layer 12 above the light strip 6 will gradually become thinner, so that more light can pass through the cylinder 4 and the frosted layer 12. As the pressure on the touch pad 15 increases, the light emitted from the position of the cylinder 4 will also increase, so that the pressure on the touch pad 15 can be visualized.

[0026] See also Figure 1-7 The utility model provides a technical solution: two limit frames 16 are symmetrically connected to the upper surface of the bottom plate 1, and the end of the spring sheet 10 away from the cylinder 4 passes through the corresponding limit frame 16.

[0027] During operation, the limit frame 16 can be used to limit the movement of one end of the spring sheet 10 to prevent the spring sheet 10 from being offset when moving.

[0028] See also Figure 1-7 The utility model provides a technical solution: an annular groove 17 is opened on one side of the side plate 3 away from the coil spring 8, and one end of the corresponding cylinder 4 extends into the annular groove 17, and one end of the cylinder 4 is slidably connected to the inner wall of the annular groove 17.

[0029] During operation, the annular groove 17 can limit one side of the cylinder 4, so that the rotation process of the cylinder 4 is more stable.

[0030] See also Figure 1-7 The utility model provides a technical solution: the outer surface of the spring sheet 10 is covered with rubber.

[0031] During operation, the setting of the rubber can prevent the spring sheet 10 from making hard contact with the touch panel 15, thereby reducing wear.

[0032] See also Figure 1-7 The utility model provides a technical solution: the frame 2 and the partition 14 are connected to a sealing sheet 18 on one side thereof, and the sealing sheet 18 is made of rubber.

[0033] During operation, the sealing performance between the cylinder 4 and the frame 2 and the partition 14 can be improved by setting the sealing sheet 18 .

[0034] See also Figure 1-7 The utility model provides a technical solution: a through opening 19 is formed through the outer surface of the side plate 3 away from the coil spring 8 .

[0035] During operation, the opening 19 is provided to facilitate an external power supply line to pass through the opening 19 and be connected to the light strip 6 .

[0036] See also Figure 1-7 The utility model provides a technical solution: the inner width of the limit frame 16 is greater than the width of the spring sheet 10.

[0037] During operation, the width of the limit frame 16 is set larger to prevent excessive friction between the limit frame 16 and the spring sheet 10 , thereby facilitating the movement of one end of the spring sheet 10 .

[0038] In summary, when the touch pad 15 is pressed, the sensor detects the change in the surface capacitance of the touch pad 15, and the sensor converts the change into an electrical signal and transmits it to the control chip 13. The control chip 13 controls the light strip 6 to emit light. When the touch pad 15 is pressed down, the spring sheet 10 is squeezed, so that one end of the spring sheet 10 moves away from the cylinder 4, thereby pulling the pull rope 11. The pull rope 11 drives the turntable 9, the connecting rod 7, the cylinder 4, and the frosted layer 12 to rotate, and the coil spring 8 contracts. As the cylinder 4 rotates, the frosted layer 12 above the light strip 6 will gradually become thinner, so that more light can pass through the cylinder 4 and the frosted layer 12. As the pressure on the touch pad 15 increases, the light emitted from the position of the cylinder 4 will also increase, so that the pressure on the touch pad 15 can be visualized. After releasing the touch pad 15, the coil spring 8 releases kinetic energy, so that the connecting rod 7, the turntable 9, the cylinder 4, and the frosted layer 12 rotate back to the initial angle.
