DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 7 A control panel for HMI includes a panel body 1, a touch control mechanism 2 is installed inside the panel body 1, and a physical button mechanism 3 is installed at the bottom of the panel body 1.

[0030] The panel body 1 comprises a panel housing 101 . The left and right sides of the panel housing 101 are both fixedly connected with handles 102 . An adjustment cavity for accommodating the touch control mechanism 2 is provided inside the panel housing 101 .

[0031] By providing the handle 102 , it is convenient for the user to place the other hand when operating with one hand, and the touch control mechanism 2 can be rotated and adjusted inside the adjustment cavity.

[0032] Furthermore, four corners of the bottom of the panel housing 101 are fixedly connected with mounting flanges 103 , and a plurality of mounting holes are formed on the mounting flanges 103 .

[0033] By providing the mounting flange 103 , the panel housing 101 can be easily mounted on the human-machine exchange device.

[0034] Furthermore, the touch control mechanism 2 includes a controller 201 located in the inner cavity of the panel housing 101, a touch screen 203 is installed inside the controller 201, a rotating rod 206 is rotatably connected to the bottom of the controller 201, sliders 204 are sleeved on the left and right ends of the rotating rod 206, a slide rail 205 is slidably connected to the surface of the slider 204, an arc-shaped rack 211 is connected to the bottom of the controller 201, and a gear 213 is meshed on one side of the arc-shaped rack 211.

[0035] Furthermore, the gear 213 is rotatably connected to a frame 215, a limiting rod 217 is installed on the frame 215, an arc-shaped rack 211 is movably sleeved on the surface of the limiting rod 217, and a hollow cavity used in conjunction with the limiting rod 217 is opened on the arc-shaped rack 211. Installation rods 209 are installed on both sides of the frame 215, and a fixing sleeve 210 fixedly connected to the inner wall of the panel shell 101 is sleeved on the surface of the installation rod 209.

[0036] Furthermore, a driving pulley 208 and a driven pulley 212 are rotatably connected on one side of the frame 215, and a belt 214 is transmission-connected to the driving pulley 208 and the driven pulley 212. The output shaft of the driven pulley 212 is connected to the gear 213. A stepper motor 216 is installed on the other side of the frame 215, and the output shaft of the stepper motor 216 is connected to the input shaft of the driving pulley 208.

[0037] By setting up the touch control mechanism 2, it is convenient for users to perform catalytic operations, and the use angle of the touch screen 203 can be changed to adapt to different working heights and viewing angles of the staff, ensuring that the user can obtain the best visual experience and touch operation convenience no matter what posture they are in. By adjusting the inclination angle of the touch screen 203, it helps to reduce visual fatigue and improve the comfort of observing the screen for a long time. Angle adjustment can also reduce reflections and improve the visibility of the touch screen 203 outdoors or in strong light environments.

[0038] When adjusting the use angle of the touch screen 203, start the stepper motor 216, the output shaft of the stepper motor 216 drives the active pulley 208 to rotate, and the active pulley 208 drives the driven pulley 212 and the gear 213 to rotate through the belt 214. When the gear 213 rotates inside the frame 215, it drives the arc rack 211 to move upward or downward in an arc shape, thereby driving the controller 201 to rotate on the surface of the rotating rod 206 to change the use angle of the touch screen 203. When the controller 201 rotates, the slider 204 is driven by the rotating rod 206 to slide on the inner wall of the slide rail 205, so that the controller 201 can be tilted smoothly. During the movement of the arc rack 211, the limit rod 217 slides inside the arc rack 211 to limit the arc rack 211 so that it is always located in the inner cavity of the frame 215.

[0039] The fixing sleeve 210 and the mounting rod 209 support the left and right sides of the frame 215 so that the frame 215 can be fixed in the inner cavity of the panel housing 101 .

[0040] Furthermore, a connector 202 is fixedly installed on the top of the controller 201 . The number of connectors 202 is several and evenly distributed on the top of the controller 201 .

[0043] When the protrusion slides inside the slide groove 207 , the slider 204 is limited to prevent it from falling off the inner cavity of the slide rail 205 .

[0044] Furthermore, the physical button mechanism 3 includes a keyboard 301 , on which a control button 304 is installed.

[0045] Furthermore, buckle tongues 306 are installed on both the left and right sides of the keypad 301 , and spring buckles 305 are installed on the buckle tongues 306 . The spring buckles 305 are connected to the left and right sides of the panel housing 101 .

[0046] Furthermore, both left and right sides of the keyboard 301 are rotatably connected with connecting members 302 , and one side opposite to the connecting member 302 is rotatably connected with a fixing rod 303 , and the fixing rod 303 is connected to the bottom front side of the panel housing 101 .

[0047] Furthermore, there are a plurality of control buttons 304 , which are evenly distributed at the bottom of the keyboard 301 .

[0048] By setting up a physical button mechanism 3, another interaction method besides touch operation can be provided for the staff. The physical button is particularly suitable for use in scenarios that are not suitable for direct touch screen operation, such as wearing gloves, holding tools, or having wet or dirty hands, to ensure effective control under special working conditions. Moreover, the physical button mechanism 3 is designed to be foldable and storable, which means that it can be hidden when not in use, keeping the surface of the control panel clean and tidy, reducing the risk of accidental touch, and at the same time reducing the space occupied by the equipment, thereby improving the compactness and professionalism of the overall appearance.

[0049] When the keypad 301 is needed, the spring buckle 305 is removed from the buckle tongue 306 to unlock the keypad 301, and the keypad 301 is rotated forward. The keypad 301 is rotated on the fixing rod 303 through the connecting piece 302 so that the bottom of the keypad 301 faces upward, making it convenient for the staff to use the control buttons 304 on the keypad 301 to operate the control panel.

[0050] When the physical key mechanism 3 needs to be folded, the keypad 301 is turned over to the inclined surface at the front bottom side of the panel housing 101 , and the spring buckle 305 is clamped on the buckle tongue 306 to fix the keypad 301 .

[0051] Furthermore, the controller 201 is electrically connected to the connector 202 , the touch screen 203 and the control button 304 , respectively.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
