Description
Technical Field
[0001] This invention relates to the field of switch panel technology, and more specifically to a button panel. Background Technology
[0002] Commercially available button panels generally face space layout challenges when integrating TOF sensing modules. Since the working principle of TOF sensing modules requires a certain amount of space for light emission and reception, traditional designs often need to reserve a dedicated window or create a specific area to house this module. This inevitably occupies valuable space on the button panel, resulting in a corresponding reduction in the area actually available for physical buttons or touch areas.
[0003] Therefore, the problem to be solved is how to minimize the impact of the TOF sensing module on the button panel space while ensuring its performance. Utility Model Content
[0004] In order to minimize the impact of the TOF sensing module on the button panel space while ensuring the performance of the TOF sensing module, this application provides a button panel.
[0005] This application provides a button panel, which adopts the following technical solution:
[0006] A button panel includes a base, buttons, and a TOF sensor. The buttons are mounted on the base, and there is a gap between both ends of the buttons and the base. The buttons are arranged in a wave-shaped structure, and the peaks and troughs of the wave-shaped structures of adjacent buttons are in opposite positions. The TOF sensor is disposed on the side of the peak of one of the wave-shaped structures of the buttons.
[0007] By adopting the above technical solution, the TOF sensor is placed on the side of the crest of the wave-shaped structure of the button. Since the trough of the adjacent button corresponds to the position of the TOF sensor, it will not be blocked by the adjacent button. At the same time, there is no need to set a separate position on the panel for installation. This can minimize the impact on the button panel space while ensuring the performance of the TOF sensing module.
[0008] Optionally, it also includes a mounting plate, which is installed inside the base. The button and the TOF sensor are both disposed on the mounting plate. The mounting plate is provided with a fixing seat, and the TOF sensor is installed on the fixing seat. A clearance groove is provided on the side of the button, and the TOF sensor is located in the clearance groove.
[0009] Optionally, the inner wall of the base is provided with a snap-fit component, the mounting plate is inside the base, and the snap-fit component snaps onto the side of the mounting plate opposite to the base.
[0010] By adopting the above technical solution, the mounting plate can be easily fixed.
[0011] Optionally, a fixing post is connected to the fixing base, and a fixing hole is opened on the TOF sensor, into which the fixing post is inserted.
[0012] By adopting the above technical solution, it is possible to locate the installation position of the TOF sensor and to install the TOF sensor stably.
[0013] Optionally, it also includes a circuit board, which is mounted on the side of the mounting plate facing the base. The mounting plate has mounting holes, and the circuit board has connection holes corresponding to the mounting holes. One end of the TOF sensor passes through the mounting holes and the connection holes in sequence and is electrically connected to the circuit board.
[0014] Optionally, the mounting plate has metal springs that correspond one-to-one with the two sides of the button. When one end of the button is pressed, the button presses the metal spring to the circuit board to connect the corresponding circuit.
[0015] Optionally, when the wavy trough of the button is in the middle, a rotating column is connected to the trough of the button, and a rotating groove is opened at the corresponding position of the mounting plate, and the rotating column is rotatably connected in the rotating groove.
[0016] By adopting the above technical solution, since both sides are wave crests, they will vibrate when pressed. Therefore, by rotating the column, it is easy to press one end of the button.
[0017] Optionally, when the wavy trough of the button is in the middle, the button is connected to a first limiting member at both ends. The mounting plate has a first limiting groove, the first limiting member extends into the first limiting groove, and when one side of the button is pressed, the first limiting member on the other side is engaged with one side of the mounting plate.
[0018] By adopting the above technical solution, the button can be limited by the snap-fit of the first limiting member, so that the rotation angle is just enough to open the corresponding circuit.
[0019] Optionally, when the wavy trough of the button is located at both ends, a second limiting member is connected to both ends of the button. The mounting plate has a second limiting groove, and the second limiting member extends into the second limiting groove. When one side of the button is pressed, the second limiting member on the other side is engaged with one side of the mounting plate.
[0020] Optionally, when the wave-shaped trough of the button is located at both ends, a guide post is provided near the two ends of the button, and a guide groove is provided on the mounting plate. The diameter of the guide groove is larger than the outer diameter of the guide post, and the guide post is inserted into the guide groove.
[0021] By adopting the above technical solution, the guide groove can limit and guide the pressing position of the button, so that the button can be pressed better.
[0022] In summary, this application includes the following beneficial technical effects:
[0023] 1. The TOF sensor is placed on the side of the crest of the wave-shaped structure of the button. Since the trough of the adjacent button corresponds to the position of the TOF sensor, it will not be blocked by the adjacent button. At the same time, there is no need to set up a separate position on the panel for installation. This can minimize the impact on the button panel space while ensuring the performance of the TOF sensing module.
[0024] 2. This allows the button to be limited by the locking mechanism of the first limiting component, so that the rotation angle is just enough to open the corresponding circuit. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0036] This application discloses a button panel. (Refer to...) Figure 1 The button panel includes a base 1, buttons 2, and a TOF sensor 3. Button 2 is mounted on the base 1, with gaps between both ends of button 2 and the base 1, allowing the buttons 2 to be pressed to open or close. Button 2 has a wave-shaped structure, with the peaks and troughs of adjacent buttons 2 being opposite in position. Button 2 has either peaks at both ends and a trough in the middle, or vice versa. In this embodiment, four buttons 2 are provided, two with troughs in the middle and two with peaks in the middle, arranged alternately; that is, along one side of the base 1 to the other, the arrangement of buttons 2 is: buttons 2 with troughs in the middle, buttons 2 with peaks in the middle, buttons 2 with troughs in the middle, and buttons 2 with peaks in the middle.
[0037] The TOF sensor 3 is located on the side of the crest of the wave-shaped structure of one of the buttons 2. In this embodiment, the TOF sensor 3 is located on the side of the second button 2 with a wave crest in the middle. Due to the obstruction of the front of the button 2, the TOF sensor 3 can function from the side, and is not visible from the front, making the button panel more aesthetically pleasing. Furthermore, there is no need to specifically reserve an installation space on the panel, allowing for a larger area for the physical buttons 2 or touch areas. This minimizes the impact on the button panel space while ensuring the performance of the TOF sensing module.
[0038] Reference Figure 2 and Figure 3 In some embodiments, a snap-fit member 9 is provided on the inner side wall of the base 1, and the mounting plate 4 is located inside the base 1. The snap-fit member 9 snaps onto the side of the mounting plate 4 opposite to the base 1, thereby fixing the mounting plate 4 toward one side of the base 1. In this embodiment, snap-fit members 9 are provided on both opposite side walls of the base 1, which allows for a more stable fixation of the mounting plate 4.
[0039] In some embodiments, the mounting plate 4 has metal springs 13 that correspond one-to-one with the two sides of the button 2. When one end of the button 2 is pressed, the button 2 presses the metal springs 13 to connect the corresponding circuit to the circuit board 10.
[0040] Reference Figure 4 In some embodiments, the button panel further includes a mounting plate 4, which is installed inside the base 1. The button 2 and the TOF sensor 3 are both mounted on the mounting plate 4. The mounting plate 4 is provided with a fixing seat 5, the surface of which is inclined to cooperate with... Figure 1 Furthermore, when button 2 is installed, the mounting base 5 is tilted towards the top of the trough of the adjacent button 2. The TOF sensor 3 is installed on the mounting base 5, and a clearance groove 6 is provided on the side of button 2. The TOF sensor 3 is located in the clearance groove 6, so that button 2 can better cover the TOF sensor 3 from the front, ensuring the aesthetics of the button panel.
[0041] In some embodiments, a fixing post 7 is integrally connected to the fixing base 5, and a fixing hole 8 is provided on the TOF sensor 3. The fixing post 7 is inserted into the fixing hole 8. In this embodiment, two fixing posts 7 are arranged at intervals, so that the installation position of the TOF can be positioned and the installation can be carried out stably.
[0042] Reference Figure 5 In some embodiments, the button panel further includes a circuit board 10, which is mounted on the side of the mounting plate 4 facing the base 1. The mounting plate 4 has mounting holes 11, and the circuit board 10 has connection holes 12 corresponding to the mounting holes 11. One end of the TOF sensor 3 passes through the mounting holes 11 and the connection holes 12 in sequence and is electrically connected to the circuit board 10. The TOF sensor 3 can be easily connected to the circuit board 10 without occupying other areas of the panel.
[0043] Reference Figure 6 and Figure 7 In some embodiments, when the wavy trough of button 2 is in the middle, a rotating post 15 is connected to the trough of button 2, and a rotating groove 14 is opened at the corresponding position of the mounting plate 4. The rotating post 15 is rotatably connected in the rotating groove 14, so that both sides of button 2 can be pressed smoothly.
[0044] Continue to refer to Figure 7In some embodiments, when the wavy trough of button 2 is in the middle, first limiting members 16 are connected to both ends of button 2. Mounting plate 4 has a first limiting groove 17, the length of which is greater than the length of the first limiting member 16. The first limiting member 16 extends into the first limiting groove 17, and when one side of button 2 is pressed, the first limiting member 16 on the other side engages with one side of mounting plate 4. The engaging and limiting action of the first limiting member 16 not only fixes button 2 but also limits the pressing depth of button 2.
[0045] In some embodiments, when the wavy troughs of button 2 are located at both ends, a second limiting member 18 is connected to each end of button 2. The mounting plate 4 has a second limiting groove 19, the length of which is greater than the length of the second limiting member 18. The second limiting member 18 extends into the second limiting groove 19, and when one side of button 2 is pressed, the second limiting member 18 on the other side engages with one side of the mounting plate 4.
[0046] In some embodiments, when the wavy troughs of button 2 are located at both ends, guide posts 20 are provided near the ends of button 2, and a guide groove 21 is provided on the mounting plate 4. The diameter of the guide groove 21 is larger than the outer diameter of the guide post 20. The guide groove 21 is oblong, and the guide post 20 is inserted into the guide groove 21. This allows for guiding and limiting the pressing position of button 2.
[0047] The implementation principle of a button panel in this application embodiment is as follows: the TOF sensor 3 is set on the side of the wave crest of the wave-shaped structure of the button 2. Since the trough of the adjacent button 2 corresponds to the position of the TOF sensor 3, it will not be blocked by the adjacent button 2. At the same time, there is no need to set a separate position on the panel for installation. While ensuring the performance of the TOF sensing module, its impact on the button panel space can be minimized.
