Description

Technical Field

[0001] The utility model relates to the technical field of printer buttons, in particular to a hidden printer button based on a deformation sensor. Background Art

[0002] Using hidden buttons on printers creates a cleaner, simpler appearance. Without conspicuous physical buttons, the overall design appears more streamlined, in line with the aesthetics of modern devices. Furthermore, hidden buttons are typically located on the surface of the device, making cleaning easier. This is beneficial for maintaining the appearance and hygiene of the device. Furthermore, traditional physical buttons wear out due to frequent pressing, while hidden buttons generally do not involve mechanical movement, making them less susceptible to physical wear and tear over long-term use.

[0003] Currently, most printer buttons on the market are physical buttons or capacitive buttons, which need to rely on PCBs to implement. They involve components such as keycaps, button bodies, PCB boards, button brackets, etc., and involve many parts, making assembly more complicated. Involving PCB button boards, the cost is relatively high. For some EMC scenarios, the electrostatic protection reliability of the buttons is poor.

This device provides waterproof and dustproof functions for the buttons to increase the service life of the printer. However, touch screens are prone to durability issues. Long-term use may cause problems such as decreased touch screen sensitivity, dead zones, or delayed response. The utility model provides a strain gauge to control the printer, and the utility model cleans and controls the strain gauge in real time, thereby increasing the service life of the strain gauge, controlling the sensitivity of the signal emitted by the strain gauge, and avoiding accidental touches caused by the printer's own shaking or external impact.

[0029] refer to Figures 1 to 11 The hidden button of a printer based on a deformation sensor shown in the figure includes a transmission component 1 for installing and transmitting the signal of a strain gauge 107. At the same time, the transmission component 1 can clean the area around the strain gauge 107 to prevent the strain gauge 107 from causing signal transmission errors due to excessive dust around it. A support component 2 is provided at the bottom of the transmission component 1 to fix the printer. A detection component 3 is provided inside the transmission component 1 to detect the pressure applied to the printer casing, thereby changing the sensitivity of the strain gauge 107 to prevent accidental touch by the staff.

[0030] The transmission component 1 includes a housing 101, a support frame 102 is provided inside the housing 101, the support frame 102 is used to support the housing 101, a mainboard 103 and a collection box 112 are provided inside the support frame 102, a strain gauge 107 is provided on the inner wall of the housing 101, and the strain gauge 107 is connected to the mainboard 103 through a connecting circuit 108. When the position where the strain gauge 107 is provided on the housing 101 is pressed, the housing 101 is deformed, and then the housing 101 triggers the strain gauge 107, and the strain gauge 107 transmits the model to the mainboard 1 through the connecting circuit 108. 03, the main board 103 controls the operation of the printer, and a mounting block 109 is also slidably provided inside the housing 101. An adsorption head 113 is provided inside the mounting block 109. The adsorption head 113 adsorbs the dust near the strain gauge 107. An adsorption tube 110 is provided on the mounting block 109. The adsorption tube 110 slides in the collection pipe 111. The collection pipe 111 is provided inside the housing 101. One end of the adsorption tube 110 is connected to the adsorption head 113, and the other end of the adsorption tube 110 is connected to the collection pipe 111. One end of the collection pipe 111 is connected to the collection box 112. The other end of the collecting pipe 111 is connected to the collecting pipe 111. After the adsorption head 113 adsorbs the dust, the dust enters the collecting pipe 111 through the adsorption tube 110, and then enters the collecting box 112 through the collecting pipe 111, completing the collection of the dust to avoid dust accumulation at the strain gauge 107 and affecting the sensitivity of the strain gauge 107. There are also multiple sets of mounting brackets 114 and springs 105 inside the housing 101. The spring 105 is provided with an impact head 115. When the printer is working, the housing 101 shakes, and the housing 101 drives the spring 105 to move. Spring 105 vibrates, and spring 105 drives the impact head 115 to vibrate. Multiple sets of detection plates 106 are slidingly set in the mounting frame 114. When the impact head 115 vibrates, it knocks the detection plate 106. A pressure sensor is set on the detection plate 106. When the detection plate 106 is subjected to pressure, the pressure exerted on the detection plate 106 is analyzed to judge the degree of vibration of the housing 101, and the force sensitivity of the strain gauge 107 is changed in real time to avoid the strain gauge 107 being accidentally touched when the housing 101 vibrates, issuing instructions to the printer, and affecting the printing effect.

[0031] The support assembly 2 includes a lifting frame 205 slidably mounted inside the mounting column 104, and a connecting rod 1 203 is rotatably provided on both sides of the lifting frame 205. A connecting rod 204 is slidably provided on the connecting rod 1 203. The connecting rod 204 is rotatably connected to the support plate 201, and the support plate 201 is slidably mounted on the housing 101. A spring 3 is provided between the connecting rod 1 203 and the connecting rod 204. A torsion spring is provided at the rotation position of the connecting rod 1 203 and the lifting frame 205. A support plate 202 is slidably provided inside the lifting frame 205, and a spring 206 is provided between the support plate 202 and the lifting frame 205 to drive the lifting frame 205 to move upward. When sliding in the mounting column 104, the lifting frame 205 drives the support plate 202 and the support plate 201 to move synchronously. When the support plate 202 is in contact with the ground, the lifting frame 205 continues to drive the movement, and the lifting frame 205 drives the support plate 201 to continue to move. When the support plate 201 is in contact with the ground, the connecting rod 204 slides in the connecting rod 1 203, and the spring 3 is squeezed. At the same time, the torsion spring on the connecting rod 1 203 and the lifting frame 205 are subjected to force. At this time, the support plate 201 and the support plate 202 are both in contact with the ground, and the support plate 201 and the support plate 202 are fixed by the lifting frame 205 to complete the fixation of the printer.

[0032] The detection component 3 includes an adjustment frame 303 slidably mounted on the mounting post 104, a rotating column 305 is rotatably provided on the adjustment frame 303, a swing column 302 is rotatably provided on the rotating column 305, a detection head 301 is slidably provided on one end of the swing column 302, and a limiting ball 306 is provided on the other end of the swing column 302, a lifting plate 304 is slidably provided on the adjustment frame 303, an annular groove is provided on the upper end of the lifting plate 304, and the limiting ball 306 slides in the annular groove. When the rotating column 305 is driven to rotate, the rotating column 305 drives the swing column 302 to rotate, and the swing column 302 drives the limiting ball 306 to rotate, and the limiting ball 306 rotates inside the lifting plate 304 to adjust the position of the detection head 301. At this time, the detection head 301 rotates along the axis of the rotating column 305 to adjust the position of the detection head 301. When the lifting plate 304 is driven to slide on the adjustment frame 303, the lifting plate 304 brings The movable limit ball 306 moves, and the limit ball 306 drives the swing column 302 to rotate, and the swing column 302 drives the detection head 301 to move. At this time, the detection head 301 rotates along the axis of the swing column 302 to complete the adjustment of the position of the detection head 301. When the position of the detection head 301 is adjusted, the detection head 301 is driven to slide on the swing column 302 so that the detection head 301 is in contact with the inner wall of the shell 101. The detection head 301 detects the pressure applied to the shell 101 and changes the control sensitivity of the strain gauge 107 in real time. When the mounting column 104 is driven to rotate, the mounting column 104 drives the adjustment frame 303 to rotate, and the adjustment frame 303 drives the detection head 301 to change its position, and drives the adjustment frame 303 to slide on the mounting column 104. The adjustment frame 303 changes the position of the detection head 301, and the shell 101 can be in contact with various positions of the inner wall, thereby realizing all-round detection of the interior of the shell 101 and improving the detection accuracy.

[0033] Working principle: When the printer needs to be used, the lifting frame 205 is driven to slide in the mounting column 104, and the lifting frame 205 drives the support plate 202 and the support plate 201 to move synchronously. When the support plate 202 is in contact with the ground, the lifting frame 205 continues to be driven to move, and the lifting frame 205 drives the support plate 201 to continue to move. When the support plate 201 is in contact with the ground, the connecting rod 204 slides in the connecting rod 1 203, and the spring 3 is squeezed. At the same time, the connecting rod 1 203 and the torsion spring on the lifting frame 205 are subjected to force. At this time, the support plate 201 and the support plate 202 are both in contact with the ground, and the support plate 201 and the support plate 202 are fixed by the lifting frame 205 to complete the fixation of the printer, pressing the position where the strain gauge 107 is installed on the shell 101, and the shell 101 is deformed. The shell 101 drives the strain gauge 107 to deform, and the strain gauge 107 sends a signal to the main board 103 through the connecting circuit 108 to complete the operation of the printer.

[0034] After the printer has been working for a period of time, the area around the strain gauge 107 is cleaned, and the mounting block 109 is driven to move on the housing 101. At the same time, the adsorption head 113 is driven to work. The adsorption head 113 adsorbs the dust near the strain gauge 107, thereby increasing the dust adsorption range of the adsorption head 113 and ensuring the cleanliness of the area around the strain gauge 107. The adsorbed dust is transported through the adsorption tube 110 and the collection pipeline 111, and the dust reaches the collection box 112, completing the collection of the dust, avoiding dust accumulation, and ensuring the sensitivity of the strain gauge 107.

[0035] When the printer is working, the shell 101 will vibrate, and the shell 101 drives the spring 105 to vibrate. When the spring 105 vibrates, it drives the impact head 115 to impact the detection plate 106. By analyzing the force of the pressure sensor on the detection plate 106, the degree of vibration of the shell 101 is judged, and then the force sensitivity of the strain gauge 107 is changed to avoid the strain gauge 107 being accidentally triggered due to the vibration of the shell 101.

[0036] When the printer is working, the shell 101 will inevitably be subjected to external force, and deformation will occur on the shell 101, which will then send an erroneous signal to the strain gauge 107. To avoid such a situation, it is necessary to detect the pressure on the shell 101 in real time and change the trigger sensitivity of the strain gauge 107. When detecting the pressure on the shell 101, when the rotating column 305 is driven to rotate, the rotating column 305 drives the swing column 302 to rotate, and the swing column 302 drives the limiting ball 306 to rotate. The limiting ball 306 rotates inside the lifting plate 304 to adjust the position of the detection head 301. At this time, the detection head 301 rotates along the axis of the rotating column 305 to adjust the position of the detection head 301. When the lifting plate 304 is driven to slide on the adjustment frame 303, the lifting plate 304 drives the limiting ball 306 to move, and the limiting ball 306 brings The swing column 302 rotates, and the swing column 302 drives the detection head 301 to move. At this time, the detection head 301 rotates along the axis of the swing column 302 to complete the adjustment of the position of the detection head 301. When the position of the detection head 301 is adjusted, the detection head 301 is driven to slide on the swing column 302 so that the detection head 301 fits against the inner wall of the shell 101. The detection head 301 detects the pressure applied to the shell 101 and changes the control sensitivity of the strain gauge 107 in real time. When the mounting column 104 is driven to rotate, the mounting column 104 drives the adjustment frame 303 to rotate, and the adjustment frame 303 drives the detection head 301 to change its position. The adjustment frame 303 is driven to slide on the mounting column 104, and the adjustment frame 303 changes the position of the detection head 301. The shell 101 can fit against various positions of the inner wall, and the pressure applied to it is detected after fitting.
