Description

Technical Field

[0001] This invention relates to the field of printer button technology, and in particular to a hidden printer button based on a deformation sensor. Background Technology

[0002] Using hidden buttons on a printer makes the device look cleaner and simpler. Without conspicuous physical buttons, the overall design looks more streamlined, meeting the aesthetic demands of modern devices. Hidden buttons are usually located on the surface of the device, making cleaning easier and contributing to better maintenance and hygiene. Furthermore, traditional physical buttons wear down with frequent pressing, while hidden buttons, which are generally not involved in mechanical movement, are less susceptible to physical wear over long-term use.

[0003] Most printer buttons on the market are physical or capacitive buttons, which require PCBs for implementation. This involves keycaps, button bodies, PCB boards, button brackets, and other components, making assembly complex due to the large number of parts involved. The PCB button board also increases costs. Furthermore, the electrostatic discharge protection of the buttons is less reliable in some EMC scenarios.

[0004] Chinese utility model patent CN205563524U discloses a touch button structure for a printer and a printer. This device provides waterproof and dustproof functions for the buttons, improving the printer's lifespan. However, touch screens are prone to durability issues, and prolonged use may lead to decreased touch screen sensitivity, dead zones, or delayed responses. This invention uses strain gauges to control the printer and performs real-time cleaning and control of the strain gauges, improving their lifespan and controlling the sensitivity of the signals emitted by the strain gauges to prevent accidental touches caused by printer vibration or external impacts.

Detailed Implementation

[0029] refer to Figures 1 to 11 The printer hidden button shown includes a transmission component 1 for mounting and transmitting signals from a strain gauge 107. The transmission component 1 can also clean the area around the strain gauge 107 to prevent signal transmission errors caused by excessive dust. 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 on the printer casing and thereby change the sensitivity of the strain gauge 107 to prevent accidental activation by the operator.

[0030] Transmission component 1 includes a housing 101, inside which a support frame 102 is disposed to support the housing 101. The support frame 102 houses a main board 103 and a collection box 112. Strain gauges 107 are disposed on the inner wall of the housing 101. The strain gauges 107 are connected to the main board 103 via a connection circuit 108. When the position on the housing 101 where the strain gauges 107 are disposed is pressed, the housing 101 deforms, thereby triggering the strain gauges 107. The strain gauges 107 transmit the signal to the main board 103 via the connection circuit 108. 03. The mainboard 103 controls the printer's operation. Inside the outer casing 101, a mounting block 109 is slidably mounted. Inside the mounting block 109 is an adsorption head 113, which adsorbs dust near the strain gauge 107. An adsorption tube 110 is mounted on the mounting block 109 and slides within a collection pipe 111, which is located inside the outer casing 101. One end of the adsorption tube 110 is connected to the adsorption head 113, and the other end is connected to the collection pipe 111. One end of the collection pipe 111 is connected to a collection box 112. The other end of the manifold 111 is connected to the collection pipe 111. After the adsorption head 113 adsorbs the dust, the dust enters the collection pipe 111 through the adsorption pipe 110, and then enters the collection box 112 through the collection pipe 111, thus completing the collection of dust and preventing dust from accumulating at the strain gauge 107 and affecting the sensitivity of the strain gauge 107. The housing 101 is also equipped with multiple sets of mounting brackets 114 and springs 105. The springs 105 are equipped with impact heads 115. When the printer is working, the housing 101 vibrates, and the housing 101 drives the springs 115 to vibrate. When spring 105 vibrates, it causes the impact head 115 to vibrate. Multiple sets of detection plates 106 are slidably arranged inside the mounting bracket 114. When the impact head 115 vibrates, it strikes the detection plates 106. The detection plates 106 are equipped with pressure sensors. When the detection plates 106 are subjected to pressure, the degree of vibration of the outer shell 101 is determined by analyzing the pressure on the detection plates 106. The force sensitivity of the strain gauge 107 is adjusted in real time to prevent the strain gauge 107 from being accidentally triggered when the outer shell 101 vibrates, thus avoiding sending instructions to the printer and affecting the printing effect.

[0031] Support assembly 2 includes a lifting frame 205 slidably mounted inside the mounting column 104. Connecting rods 1 203 are rotatably mounted on both sides of the lifting frame 205. Connecting rod 204 is slidably mounted on connecting rod 1 203 and is rotatably connected to a support plate 201. The support plate 201 is slidably mounted on the outer shell 101. A spring 3 is provided between connecting rod 1 203 and connecting rod 204. A torsion spring is provided at the rotatable position of connecting rod 1 203 and the lifting frame 205. A support plate 202 is slidably mounted inside the lifting frame 205. A spring 206 is provided between the support plate 202 and the lifting frame 205, driving the lifting frame 205 to... When the mounting column 104 slides, 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 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, the spring 3 is compressed, and at the same time the torsion spring on the connecting rod 1 203 and the lifting frame 205 is stressed. At this time, the support plate 201 and the support plate 202 are both in contact with the ground, and the lifting frame 205 fixes the support plate 201 and the support plate 202, thus completing the fixation of the printer.

[0032] The detection assembly 3 includes an adjustment frame 303 slidably mounted on a mounting column 104. A rotating column 305 is rotatably mounted on the adjustment frame 303, and a swing column 302 is rotatably mounted on the rotating column 305. A detection head 301 is slidably mounted on one end of the swing column 302, and a limit ball 306 is mounted on the other end of the swing column 302. A lifting plate 304 is slidably mounted on the adjustment frame 303. An annular groove is provided on the upper end of the lifting plate 304, and the limit ball 306 slides within 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 limit ball 306 to rotate. The limit ball 306 rotates inside the lifting plate 304, thereby adjusting the position of the detection head 301. At this time, the detection head 301 rotates along the axis of the rotating column 305, adjusting 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... The movable limit ball 306 moves, causing the swing column 302 to rotate. The swing column 302 then moves the detection head 301. At this time, the detection head 301 rotates along the axis of the swing column 302, completing the adjustment of the position of the detection head 301. After 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 outer shell 101. The detection head 301 detects the pressure on the outer 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 adjusting frame 303 to rotate. The adjusting frame 303 drives the detection head 301 to change position. The adjusting frame 303 slides on the mounting column 104, changing the position of the detection head 301. The outer shell 101 can be in contact with various positions of the inner wall, realizing all-round detection of the interior of the outer shell 101 and improving the detection accuracy.

[0033] Working principle: When the printer needs to be used, the drive lifting frame 205 slides within the mounting column 104. The lifting frame 205 drives the support plate 202 and support plate 201 to move synchronously. When the support plate 202 is in contact with the ground, the drive lifting frame 205 continues to move, and the lifting frame 205 drives the support plate 201 to continue moving. When the support plate 201 is in contact with the ground, the connecting rod 204 slides within the connecting rod 203, and the spring 3 is compressed. At the same time, the torsion spring on the connecting rod 203 and the lifting frame 205 is stressed. At this time, both the support plate 201 and the support plate 202 are in contact with the ground, and the lifting frame 205 fixes the support plate 201 and the support plate 202, thus fixing the printer. Pressing the position where the strain gauge 107 is installed on the outer shell 101 causes the outer shell 101 to deform. The outer 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, thus completing 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. The drive mounting block 109 moves on the housing 101, and at the same time, the adsorption head 113 is driven to work. The adsorption head 113 adsorbs the dust near the strain gauge 107, 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 tube 111, and the dust reaches the collection box 112, completing the collection of dust, avoiding dust accumulation, and ensuring the sensitivity of the strain gauge 107.

[0035] When the printer is working, the outer casing 101 will vibrate. The outer casing 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 outer casing 101 is judged. Then, the force sensitivity of the strain gauge 107 is changed to prevent the strain gauge 107 from being accidentally triggered due to the vibration of the outer casing 101.

[0036] When the printer is working, the outer casing 101 is inevitably subjected to external forces, causing deformation and sending incorrect signals to the strain gauge 107. To avoid this, it is necessary to monitor the pressure on the outer casing 101 in real time and adjust the trigger sensitivity of the strain gauge 107. When monitoring the pressure on the outer casing 101, the rotating column 305 rotates, causing the swing column 302 to rotate. The swing column 302 then rotates the limit ball 306, which rotates inside the lifting plate 304, thus adjusting the position of the detection head 301. At this time, the detection head 301 rotates along the axis of the rotating column 305. When the lifting plate 304 slides on the adjusting frame 303, it moves the limit ball 306, causing the limit ball 306 to move. The swing column 302 rotates, driving the detection head 301 to move. At this time, the detection head 301 rotates along the axis of the swing column 302, completing the adjustment of the position of the detection head 301. After 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 outer shell 101. The detection head 301 detects the pressure on the outer 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. The adjustment frame 303 drives the detection head 301 to change position. The adjustment frame 303 slides on the mounting column 104, changing the position of the detection head 301. The outer shell 101 can be in contact with various positions of the inner wall, and the pressure on it can be detected after contact.
