[0034] A display device is a hardware device that converts data signals from an electronic system into visual information such as images, text, or video, and it is widely used in various fields. Display devices in related technologies include a display screen and buttons. The buttons are mounted on the display screen to control it; however, buttons in related technologies are usually mounted directly on the side of the display screen, which is not only prone to accidental touches but also affects the aesthetics of the display.

[0035] Referring to Figures 1 to 4, 9, and 10, to address the aforementioned problems, according to one aspect of this application, an embodiment provides a button mechanism for a display device. The display device includes a display screen 100 and a control switch 200, the control switch 200 being electrically connected to the display screen 100. The button mechanism includes a button portion 300 and a blocking portion 400, wherein the button portion 300 is electrically connected to the display screen 100, and the button portion 300 has an operating surface 310 and a back surface 320. The shielding part 400 is located on the side of the operating surface 310 away from the back surface 320, and is used to drive the control switch 200 to switch between the open and closed states. The shielding part 400 has a shielding position and a clearance position. When the shielding part 400 is in the shielding position, the shielding part 400 shields the operating surface 310 and drives the control switch 200 to the closed state. When the shielding part 400 is in the clearance position, the shielding part 400 moves away to expose the operating surface 310, and the shielding part 400 drives the control switch 200 to the open state.

[0036] In this embodiment, the display device is an interactive display screen 100. In other embodiments, the display device may be a television, a computer monitor, or other display devices. The control switch 200 is generally a toggle switch used to control the opening and closing of the display screen 100. In other embodiments, the control switch 200 may be a push-button switch, a rotary switch, or a slide switch. The button section 300 generally includes multiple buttons arranged at intervals. The user controls the display screen 100 by pressing the buttons in the button section 300. The blocking section 400 generally switches between a blocking position and a clearance position by reciprocating movement, and drives the control switch 200 to switch between a closed state and an open state. In other embodiments, the blocking section 400 may also switch between a blocking position and a clearance position by reciprocating rotation, and drive the control switch 200 to switch between a closed state and an open state.

[0037] When the button 300 in this application is needed, it moves the blocking part 400 to a clearance position. At this time, the blocking part 400 moves away, no longer blocking the button 300. Simultaneously, the blocking part 400 also activates the control switch 200, turning on the display screen 100. When the button 300 is not needed, it moves the blocking part 400 to a blocking position. At this time, the blocking part 400 blocks the operating surface 310 of the button 300 to prevent accidental touches and protect the button 300. Simultaneously, the blocking part 400 also activates the control switch 200, turning off the display screen 100. The blocking part 400 in this application not only blocks the operating surface 310 of the button 300, preventing accidental touches and turning off the display screen 100, thus providing protection and linkage, but also exposes the operating surface 310 of the button 300 after switching positions, allowing the button 300 to function normally and turning on the display screen 100.

[0038] Referring to Figures 1 to 6, in one embodiment, the control switch 200 includes a switch body 210 and a movable handle 220, the movable handle 220 being slidable on the switch body 210 to switch the control switch 200 between an on state and an off state; the button mechanism also includes a mounting frame 500, the button portion 300 being mounted on the mounting frame 500; the blocking portion 400 includes a blocking member 410 and a pushing block 420, wherein the blocking member 410 is movable relative to the button portion 300 in a preset direction on the mounting frame 500 to block the operating surface 310 or expose the operating surface 310; the pushing block 420 is mounted on the blocking member 410 and is used to push the movable handle 220 to slide on the switch body 210.

[0039] In this embodiment, the control switch 200 is a toggle switch, and the sliding motion of the movable handle 220 on the switch body 210 is common knowledge to those skilled in the art and will not be described in detail here. The mounting frame 500 generally has installation space, and both the shielding part 400 and the button part 300 are installed in the installation space. The mounting frame 500 serves a load-bearing and protective function.

[0040] As the blocking member 410 moves, it will either block the operating surface 310 of the button part 300 or expose the operating surface 310 of the button part 300. During this process, the push block 420 will also push the movable handle 220 to switch the control switch 200 between the on and off states.

[0041] In addition, the movable handle 220 can generally slide on the switch body 210 in a preset direction so that the push block 420 can push the movable handle 220 to slide on the switch body 210 more smoothly when it moves in the preset direction.

[0042] Referring to FIG6, in one embodiment, there are two push blocks 420. The two push blocks 420 are arranged at intervals along a preset direction, and a clamping gap is formed between the two push blocks 420 for the insertion of the movable handle 220. The two push blocks 420 can simultaneously push the movable handle 220 to slide on the switch body 210.

[0043] In this embodiment, the two surfaces of the two push blocks 420 that are close to each other generally contact the movable handle 220 simultaneously, so that the two push blocks 420 can simultaneously push the movable handle 220 to slide on the switch body 210; the two push blocks 420 ensure the smoothness of the movable handle 220 sliding on the switch body 210, thereby improving the smoothness of the control switch 200 switching between the open and closed states.

[0044] Referring to Figures 1 to 8, in one embodiment, the blocking part 400 further includes a toggle block 430, which is mounted on the blocking member 410 and is used to drive the blocking member 410 to move relative to the button part 300 in a preset direction.

[0045] In this embodiment, by applying a pulling force to the toggle block 430, the blocking member 410 can be moved relative to the button portion 300 in a preset direction; the toggle block 430 is easy to grip, thereby facilitating the movement of the blocking member 410 relative to the button portion 300 in a preset direction, improving the convenience of operation.

[0046] Referring to Figures 1 to 8, in one embodiment, the mounting frame 500 has a mounting plate 510, and a blocking member 410 is located on one side of the mounting plate 510; a button portion 300 is located on the side of the blocking member 410 away from the mounting plate 510; the mounting plate 510 is provided with a button through hole 511 and a toggle through hole 512; when the blocking member 400 is in the avoidance position, the operating surface 310 is exposed outward through the button through hole 511; a toggle block 430 is mounted on the surface of the blocking member 410 near the mounting plate 510 and passes through the toggle through hole 512; a push block 420 is mounted on the surface of the blocking member 410 away from the mounting plate 510.

[0047] In this embodiment, the key through-hole 511 generally completely covers the multiple keys on the key section 300, so that when the blocking part 400 is in the avoidance position, the operating surface 310 of the key section 300 can be exposed outward through the key through-hole 511, thereby facilitating the user to operate the key section 300 accordingly. The toggle through-hole 512 is located on one side of the key through-hole 511, and the extension direction of the toggle through-hole 512 is parallel to a preset direction, so that the part of the structure in the toggle block 430 that passes through the toggle through-hole 512 can move in the toggle through-hole 512 along the preset direction. The toggle block 430 extends through the toggle through-hole 512 to the side of the mounting plate 510 away from the key section 300 for easy gripping. In addition, the control switch 200 is located on the side of the blocking part 410 away from the mounting plate 510. This design, in which the push block 420 is mounted on the surface of the blocking part 410 away from the mounting plate 510, ensures that the toggle block 430 and the push block 420 do not interfere with each other.

[0048] Referring to Figures 1 to 4, 7 and 8, in one embodiment, the button mechanism further includes a limiting part, which includes a first limiting member 610, which is mounted on the mounting plate 510. The first limiting member 610 has a first limiting block 611, which is located on the side of the blocking member 410 away from the mounting plate 510. A first moving gap is formed between the first limiting block 611 and the mounting plate 510 to allow the blocking member 410 to move.

[0049] In this embodiment, the first limiting member 610 is generally mounted on the mounting plate 510 using fasteners such as connecting screws or connecting pins. The distance of the first moving gap is generally slightly greater than the sum of the thickness of the blocking strip 411 and the thickness of the mounting piece 412. By driving the toggle block 430 to move in a preset direction, the blocking member 410 will also move relative to the button portion 300 in the preset direction within the first moving gap.

[0050] The first limiting block 611 serves a limiting function, ensuring that the blocking member 410 can only move in a preset direction, thus guaranteeing the smooth operation of both blocking and exposing the operating surface 310. The first limiting member 610 also serves a connecting function, allowing the first limiting block 611 to connect with the mounting plate 510. Furthermore, to limit the movement range of the blocking member 410, the mounting frame 500 also has a first limiting plate and a second limiting plate. The first limiting plate is fixedly installed at the first end of the mounting plate 510, extending towards the button portion 300, and is perpendicular to the mounting plate 510. The second limiting plate is fixedly installed at the second end of the mounting plate 510, extending towards the button portion 300, and is perpendicular to the mounting plate 510.

[0051] Referring to Figures 1 to 4, 6 and 8, in one embodiment, the shielding member 410 includes a shielding strip 411 and a mounting plate 412. The shielding strip 411 can shield the operating surface 310 or expose the operating surface 310. The mounting plate 412 is mounted on the surface of the shielding strip 411 away from the mounting plate 510. A toggle block 430 is mounted on the mounting plate 412. A push block 420 is mounted on the mounting plate 412. A first limiting block 611 is in line contact with the mounting plate 412.

[0052] In this embodiment, the mounting piece 412 is generally mounted on the surface of the shielding strip 411 away from the mounting plate 510 using fasteners such as connecting screws or connecting pins; the shielding strip 411 and the mounting piece 412 not only improve the flexibility and efficiency of manufacturing, but also reduce manufacturing costs.

[0053] The actuating block 430 is fixedly installed on the surface of the mounting piece 412 near the mounting plate 510, while the blocking strip 411 has a through hole for the actuating block 430 to pass through; the pushing block 420 is fixedly installed on the surface of the mounting piece 412 away from the mounting plate 510; the surface of the first limiting block 611 near the mounting piece 412 is an arc surface, so that the first limiting block 611 and the mounting piece 412 are in line contact, thereby reducing the frictional force applied to the mounting piece 412 by the first limiting block 611 and extending the service life of the mounting piece 412 and the first limiting block 611. To facilitate identification of the status of the blocking part 400, the surface of the blocking strip 411 away from the mounting piece 412 is provided with power-on and power-off markings, which are arranged at intervals along a preset direction.

[0054] Furthermore, to facilitate the assembly of the toggle block 430, push block 420, and mounting plate 412, the toggle block 430, push block 420, and mounting plate 412 are welded or integrally formed parts. To reduce the frictional force exerted by the shielding member 410 on the mounting plate 510, a contact strip extending toward the mounting plate 510 is usually fixedly mounted on the mounting plate 412. The surface of the contact strip near the mounting plate 510 is an arc surface, so that the contact strip and the mounting plate 510 are in line contact. To ensure that the shielding member 410 moves only in a preset direction, the button part 300 has a limiting surface. The limiting surface contacts the surface of the mounting plate 412 away from the shielding strip 411, so as to limit the surface of the mounting plate 412 away from the shielding strip 411. To reduce the frictional force exerted by the limiting surface on the mounting plate 412, the surface of the mounting plate 412 near the limiting surface is an arc surface, so that the surface of the mounting plate 412 near the limiting surface is in line contact with the limiting surface.

[0055] Referring to Figures 1 to 4, 7 and 8, in one embodiment, the limiting portion further includes a second limiting member 620, which is located on one side of the first limiting member 610 and is mounted on the mounting plate 510. The second limiting member 620 has a second limiting block 621, which is located on the side of the shielding strip 411 away from the mounting plate 510. A second moving gap is formed between the second limiting block 621 and the mounting plate 510 for the shielding strip 411 to move. The distance of the second moving gap is smaller than the distance of the first moving gap, and the second limiting block 621 is in line contact with the shielding strip 411.

[0056] In this embodiment, the second limiting member 620 is generally installed on the mounting plate 510 using fasteners such as connecting screws or connecting pins. The length of the second moving gap is generally slightly greater than the thickness of the shielding strip 411. The second limiting member 620 strengthens the limiting effect on the shielding member 410, so that the shielding member 410 can only move in a preset direction, ensuring the smooth operation of operations such as shielding the operating surface 310 and exposing the operating surface 310. The surface of the second limiting block 621 near the shielding strip 411 is an arc surface, so that the second limiting block 621 and the shielding strip 411 are in line contact, thereby reducing the frictional force applied to the shielding strip 411 by the second limiting block 621 and extending the service life of the shielding strip 411 and the second limiting block 621.

[0057] Referring to Figures 1 to 4, 7 and 8, in one embodiment, the button mechanism further includes a button circuit board 700, which is mounted on the surface of the button portion 300 away from the mounting plate 510. A first limiting member 610 is connected to the button circuit board 700 so that the button portion 300 is connected to the mounting plate 510. The button circuit board 700 is electrically connected to the button portion 300 for electrical connection with the display screen 100.

[0058] In this embodiment, the button circuit board 700 is generally mounted on the surface of the button part 300 away from the mounting plate 510 using fasteners such as connecting screws or connecting pins; at the same time, the button circuit board 700 is generally fixedly connected to the first limiting member 610 using fasteners such as connecting screws or connecting pins, and the button circuit board 700 is generally fixedly connected to the second limiting member 620 using fasteners such as connecting screws or connecting pins, so as to achieve a stable connection between the button part 300 and the mounting plate 510.

[0059] Furthermore, the control switch 200 is mounted on the surface of the keypad circuit board 700 near the mounting plate 510 for electrical connection with the keypad circuit board 700. To enhance the stability of the keypad circuit board 700 on the keypad portion 300, a plurality of protrusions are provided on the surface of the keypad portion 300 near the keypad circuit board 700, and a plurality of grooves are provided on the keypad circuit board 700. The number of grooves is equal to the number of protrusions, and the plurality of grooves are arranged in a one-to-one correspondence with the plurality of protrusions. The protrusions pass through the corresponding grooves to enhance the stability of the keypad circuit board 700 on the keypad portion 300. In other embodiments, the protrusions may be provided on the keypad circuit board 700, and the grooves may be provided on the surface of the keypad portion 300 near the keypad circuit board 700.

[0060] Referring to Figures 1 to 10, according to another aspect of this application, an embodiment of this application also provides a display device, which includes a display screen 100, a control switch 200, and the aforementioned button mechanism. The control switch 200 is electrically connected to the display screen 100, and the button part 300 is mounted on the display screen 100 and electrically connected to the display screen 100.

[0061] In this embodiment, the display device is generally an interactive display screen 100. In other embodiments, the display device may also be a television, a computer monitor, or other display devices. The control switch 200 is generally a toggle switch used to control the opening and closing of the display screen 100. In other embodiments, the control switch 200 may also be a push-button switch, a rotary switch, or a slide switch.

[0062] When the button 300 in this application is needed, the blocking part 400 is moved to a clearance position. At this time, the blocking part 400 will move away and no longer block the button 300. At the same time, the blocking part 400 will also drive the control switch 200 to the open state, so that the display screen 100 is turned on. When the button 300 in this application is not needed, the blocking part 400 is moved to the blocking position. At this time, the blocking part 400 will block the operating surface 310 of the button 300 to avoid accidental touch and to protect the button 300. At the same time, the blocking part 400 will also drive the control switch 200 to the closed state, so that the display screen 100 is turned off.

[0063] Referring to Figures 1 to 10, in one embodiment, the control switch 200 is a toggle switch; the display screen 100 is provided with a mounting groove, and the button mechanism is installed in the mounting groove.

[0064] In this embodiment, the toggle switch generally includes a switch body 210 and a movable handle 220. The movable handle 220 can slide along a preset direction on the switch body 210 to switch the control switch 200 between an on and off state. The provided mounting groove not only provides a mounting location for the button mechanism and protects the button mechanism, but also improves the aesthetics of the display device. In addition, to facilitate the operation of the button mechanism, the mounting groove is provided on the front of the display screen 100, and the surface of the button mechanism near the front of the display screen 100 is flush with the front of the display screen 100.

[0065] In summary, the button mechanism and display device provided in this embodiment have at least the following beneficial technical effects: When the button part 300 in this application needs to be used, it drives the blocking part 400 to a clearance position. At this time, the blocking part 400 will move away and no longer block the button part 300. At the same time, the blocking part 400 will also drive the control switch 200 to the open state, so that the display screen 100 is turned on.
