Description

Technical Field

[0001] The present invention relates to the field of hand controllers for lifting tables, and in particular to a split-type button hand controller and a lifting table. Background Art

[0002] Height-adjustable lifting tables are widely used in scenes such as office desks, dining tables, and hospital beds. They are usually equipped with a hand controller connected to the control end of the lifting table to adjust the height of the lifting table. The functions of the lifting table include but are not limited to rising, falling, gear selection, etc. For example, the utility model patent with application number CN202120663992.1 discloses a lifting table with a hand controller including an upper shell, a control panel is provided on the top surface, and a display area and a button area are provided on the control panel. The button area is provided with an up button, a down button, a number of height memory buttons, and a setting button. When using this type of hand controller, the user must see clearly and understand the corresponding function of each button at the same time in order to correctly issue the operation instruction. The operation is not user-friendly, and with a large number of buttons, the possibility of operator error will increase.

[0003] In order to solve the above problems, a Chinese patent with publication number CN220626941 U discloses a hand controller, including a shell, a circuit board is fixedly installed in the shell, a knob device is fixedly installed on the front of the circuit board, and a touch switch is fixedly installed on the back of the circuit board corresponding to the knob device; the knob device is a brushless motor, the rotor of the brushless motor is fixedly installed on the circuit board, and a Hall element is provided on the circuit board; the gear position of the electric lifting table is adjusted by rotating the knob device, and the gear position of the electric lifting table is confirmed and the lifting operation is performed by pressing the knob device and triggering the touch switch. There is no need to set numerous buttons, and the lifting control operation of the electric lifting table is simpler, and the double operation of rotating and pressing the knob can avoid the operator's misoperation.

[0004] However, since the knob device of the hand controller is in direct contact with the circuit board, if water accidentally enters the knob gap, it is easy to directly cause damage to the circuit board, affecting the use of the entire lifting table device.

[0005] Therefore, a hand controller with simple buttons is needed, which will not affect the circuit board even if water enters the gap between the buttons. Utility Model Content

[0034] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0035] like Figures 1 to 5 As shown, a split-type button hand controller 10 of an embodiment includes a front shell 100, a bottom shell 200, a button mechanism 300, a digital display mechanism 400 and a PCB board 500. The front shell 100 is connected to the bottom shell 200, so that a receiving groove 101 is formed between the front shell and the bottom shell, the PCB board 500 is located in the receiving groove 101, and the digital display mechanism 400 is fixedly connected to the bottom shell 200.

[0036] Further, the key mechanism 300 includes a key plate 310, a key arm 320, a key fixing seat 330, a light-emitting light guide sheet 340 and a rotating shaft 350. The key plate 310 is provided with a button 311, and the key plate 310 is fixedly connected to the first end of the key arm 320. The key fixing seat 330 is fixedly connected to the bottom shell 200, and the key fixing seat 330 is provided with a receiving groove 331, and the light-emitting light guide sheet 340 is located in the receiving groove 331 and is electrically connected to the PCB board 500. The rotating shaft 350 is fixedly connected to the key plate 310, and the rotating shaft 350 is rotatably connected to the key fixing seat 330.

[0037] Furthermore, the PCB board 500 includes a lamp bead 510, a touch switch 520 and a main circuit board 530, and the main circuit board 530 is fixedly connected to the housing 100. The lamp bead 510 and the touch switch 520 are respectively arranged on two opposite sides of the main circuit board 530, that is, the lamp bead 510 is arranged on the upper surface of the main circuit board 530, and the touch switch 520 is arranged on the lower surface of the main circuit board 530. The lamp bead 510 is arranged corresponding to the light guide sheet 340, so that the light generated by the lamp bead 510 can be guided out through the light guide sheet 340. The second end of the button arm 320 extends to the side of the main circuit board 530 away from the lamp bead 510, and the second end of the button arm 320 is used to contact the touch switch 520 when the button fixing seat 330 rotates to a predetermined angle relative to the rotating shaft 350.

[0038] In this embodiment, the operation process of the split-type key hand controller 10 is as follows: the user presses the button 311, so that the key plate 310 is pressed down with the button 311. Since the rotating shaft 350 is fixedly connected to the key plate 310, the key plate 310 rotates relative to the key fixing seat 330 through the rotating shaft 350. Since the second end of the key arm 320 extends to the side of the main circuit board 530 away from the lamp bead 510, and the second end of the key arm 320 is used to contact the touch switch 520 when the key fixing seat 330 rotates to a predetermined angle relative to the rotating shaft 350, the key arm 320 contacts the touch switch 520 in a rotating manner. At this time, the lamp bead 510 lights up, and the light emitted by the lamp bead 510 is exported through the lighting light guide 340, and the lighting light guide 340 makes the light become uniform and not dazzling, which can play a lighting role when used at night. Furthermore, the corresponding functional component on the PCB board 500 is triggered, and the control end of the lifting table is electrically connected to the PCB board 500. The control end receives the electrical signal from the PCB board 500, thereby controlling the lifting table to perform the corresponding function, that is, the button mechanism 300 and the PCB board 500 have a split structure, and this rotating contact method between the button arm 320 and the touch switch 520 effectively prevents the PCB board 500 from directly contacting the button arm 320.

[0039] In the above-mentioned split-type key hand controller 10, the key mechanism 300 includes a key plate 310, a key arm 320, a key fixing seat 330, a light guide plate 340 and a rotating shaft 350. The key plate 310 is provided with a button 311. The rotating shaft 350 is fixedly connected to the key plate 310, and the rotating shaft 350 is rotatably connected to the key fixing seat 330. When the button 311 is pressed, the key plate 310 is pressed down, and the key arm 320 rotates and moves upward by rotating the rotating shaft 350 relative to the key fixing seat 330. The touch switch 520 on the PCB board 500 is arranged relative to the key arm 320, so that the key arm 320 contacts the touch switch 520 in a rotational manner, so that the lifting table performs the corresponding function. This rotational contact method can prevent the PCB board 500 from directly contacting the key arm 320. Even if water enters the key gap, it will not affect the PCB board 500, thereby maintaining the normal use of the entire lifting table.

[0040] Furthermore, a side wall of the key panel 310 is formed with a avoidance groove 312, the key fixing seat 330 is located at the avoidance groove 312, and the rotating shaft 350 is fixedly connected to the inner wall of the avoidance groove 312, so that the key panel 310 can be better rotated and connected to the key fixing seat 330 through the rotating shaft 350, and at the same time, the structure of the split-type key hand controller 10 is more compact.

[0041] like Figures 1 to 3 As shown, in one embodiment, there are multiple button mechanisms 300, and the multiple button mechanisms 300 are all connected to the bottom shell 200. It can be understood that the functions of the lifting table include but are not limited to rising, falling, gear selection, etc. These functional components are integrated on the PCB board 500, and the corresponding multiple touch switches 520 on the PCB board 500 correspond to different functional components of the PCB board 500. Each touch switch 520 is arranged relative to the button arm 320, so that the multiple button mechanisms 300 correspond to different functions of the PCB board 500. Further, the multiple button fixing seats 330 correspond to the multiple accommodating grooves 331, and the multiple accommodating grooves 331 are arranged at intervals, so that each light-emitting light guide sheet 340 has an independent light-guiding space; each button fixing seat 330 is connected to the base 200, and the multiple button fixing seats 330 are arranged at intervals, so that each lamp bead 510 has an independent light-emitting space, which effectively prevents light interference between the lamp beads 510.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the button 311 is circular, and multiple buttons 311 are arranged in parallel. It can be understood that multiple buttons 311 are arranged in parallel, that is, multiple key plates 310 are arranged in parallel, so that multiple buttons 311 are located on the same horizontal plane, so that the surface of the key mechanism 300 of the entire hand controller is arranged flat, improving the aesthetics. Further, according to different needs, the button 311 can also be rectangular or other shapes.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, each keypad 310 is provided with a function mark 313. In this embodiment, the function mark 313 is a simple function mark 313 for ascending, descending and gear selection. The function mark 313 is simple and easy to understand, and the user is not likely to make a mistake.

[0044] like Figure 2 As shown, in one embodiment, the key plate 310, the key arm 320 and the rotating shaft 350 are an integrally formed structure. It can be understood that the key plate 310, the key arm 320 and the rotating shaft 350 are integrally injection molded to improve the connection stability between the key plate 310 and the key arm 320, so that the key arm 320 will not become loose after multiple rotations.
