[0002] Smart products refer to any device, instrument, or machine with computing capabilities. Smart remote controls, also known as infrared transponders, are a basic component of smart home systems. Their function is to control corresponding electrical appliances through infrared remote control. They have the advantages of being simple, convenient, and easy to use, and have broad application prospects.

[0003] An air conditioner remote control consists of an integrated circuit board and buttons used to generate different messages. The existing air conditioner remote control works by placing conductive contacts at the bottom of the buttons on the circuit board to conduct the circuit. A cup-shaped rubber supports the conductive contacts and the keycap. However, with long-term use, the elasticity of the cup-shaped rubber decreases, causing the keycap to collapse after being pressed and unable to spring back to its original position, which is detrimental to the use of the remote control. Therefore, a smart air conditioner remote control with a self-resetting structure to prevent button collapse is proposed. Summary of the Invention

[0036] Example 1

[0037] Please see Figures 1-11As shown, the purpose of this embodiment is to provide a smart air conditioner remote control with a self-resetting structure to prevent button collapse, including a housing 1, a circuit board 2, and multiple input modules 3. The housing 1 includes a lower shell 11 and an upper shell 12 located on top of the lower shell 11. A battery compartment 111 is opened at one end of the lower shell 11, and a compartment plate is inserted into the bottom of the battery compartment 111. A main board compartment 112 is opened at the other end of the lower shell 11, and the circuit board 2 is located in the main board compartment 112. A display screen 121 is embedded on the surface of the upper shell 12 at the end away from the battery compartment 111. Multiple reserved openings 122 penetrating the surface are opened in the middle of the upper surface of the upper shell 12. The input module 3 includes a pressing body 3. 1. A receiving frame 32 is provided at the bottom of the pressing body 31. The pressing body 31 is engaged with the reserved opening 122. The receiving frame 32 is located inside the reserved opening 122. A pressure plate 33 is provided at the bottom of the receiving frame 32. Conductive adhesive 331 is provided at the bottom of the pressure plate 33. The conductive adhesive 331 is located above the circuit board 2. By pressing down the pressing body 31, the pressing body 31 moves the pressure plate 33 towards the surface of the circuit board 2 through the receiving frame 32 until the conductive adhesive 331 contacts the surface of the circuit board 2, so that the corresponding circuit on the circuit board 2 is connected. The pressing body 31 is used to realize the repeated pressing operation. The receiving frame 32 is used to drive the movement of the pressure plate 33 and assist the pressing body 31 in resetting.

[0038] In practical use, this embodiment is operated by pressing button 312 on the surface of the remote control. When button 312 is pressed, it overcomes the elastic force of the first spring, causing the rocker 313 to move downward along the circular opening. The first sliding rod moves within the first sliding groove and causes the transverse plate 321 to slide along the inner wall of the receiving frame 32. When the transverse plate 321 moves, it causes the second sliding rod to move within the second sliding groove. This causes the transverse plate 321 to rotate plate a and plate b around the circular axis, changing the angle between plate a and plate b, i.e., the end plate compresses the second spring. This causes the second spring to contract, moving the pressure plate 33, which is connected to the middle of plates a and b, downwards until the conductive adhesive 331 at the bottom of the pressure plate 33 contacts the surface of the circuit board 2. This causes the infrared emitting tube of the circuit board 2 to emit a corresponding control signal to the air conditioner. When the button 312 is released, the button 312 is pushed back to its original position by the elastic force of the first spring. Under the action of the second spring, plates a and b rotate in opposite directions, which not only helps the pressure plate 33 to reset but also assists in the reset of the button 312, thus preventing the button 312 from collapsing into the upper frame 311.

[0039] In this embodiment, to achieve repeated pressing operation, the pressing body 31 includes an upper frame 311 and a button 312 located within the upper frame 311. The upper frame 311 is located within the reserved opening 122 and is engaged with the reserved opening 122. A first bracket is provided inside the upper frame 311, and a circular opening is provided in the middle of the first bracket. A rocker plate 313 is provided at the bottom of the button 312, and a through rod is provided at the top of the rocker plate 313. The top of the through rod passes through the circular opening and is connected to the bottom of the button 312. A first spring is provided on the surface of the through rod, and the through rod is connected to the upper surface of the first bracket through the first spring. With the pressing body 31, when the button 312 is pressed, the button 312 is pressed to overcome the elastic force of the first spring, causing the rocker plate 313 to move downward. When the pressing of the button 312 is released, the button 312 is pushed back to its original position under the elastic force of the first spring, thereby achieving repeated pressing operation of the button 312.

[0040] To move the pressure plate 33, the rocker plate 313 is a square plate bent downwards at both ends. The rocker plate 313 has first sliding grooves at both ends. The top of the receiving frame 32 is connected to the bottom of the upper frame 311. A pair of transverse sliding plates 321 are slidably connected to the inner wall of the receiving frame 32. A second sliding groove is formed on the top side surface of the transverse sliding plate 321, and a first sliding rod is slidably connected within the second sliding groove. The middle of the first sliding rod is located within the first sliding groove. A third sliding groove is formed on the bottom side surface of the transverse sliding plate 321. A movable body 322 is provided at the bottom of the transverse sliding plate 321. The movable body 322 includes a pair of a plates and a pair of b plates, which are arranged in an "X" shape. The tops of the two a plates are connected by a second sliding rod. Similarly, the tops of the two b plates are connected by a second sliding rod. The second sliding rod is located within the third sliding groove and is slidably connected to the third sliding groove. The pressure plate 33 is positioned against... The top two sides are provided with round shafts, and the middle of plates a and b is provided with opening c. The round shafts pass through opening c and are rotatably connected to opening c. The outer surfaces of both ends of plates a and b are provided with plate openings. The outer surfaces of both ends of plates a and b are provided with reset bodies 323. The reset body 323 includes a second spring and end plates set at both ends of the second spring. One end of the end plate is rotatably connected to the plate opening. With the provided receiving frame 32, when the button 312 is pressed and the rocker 313 moves downward, the first slide rod moves in the first slide groove and drives the transverse plate 321 to slide along the inner wall of the receiving frame 32. When the transverse plate 321 moves, it will drive the second slide rod to move in the second slide groove, so that when the transverse plate 321 moves, it will drive plates a and b to rotate around the round shaft. The included angle between plates a and b changes, which will drive the pressure plate 33 connected to the middle of plates a and b to move downward.

[0041] To facilitate the reset of button 312 and pressure plate 33, pressure plate 33, i.e., plate a and plate b, has openings on its outer surfaces at both ends. Reset bodies 323 are provided on the outer surfaces of plates a and b. The reset body 323 includes a second spring and end plates disposed at both ends of the second spring. One end of the end plate is rotatably connected to the opening. With the reset body 323, when plates a and b rotate around the circular axis, the angle between plates a and b changes, i.e., the end plates squeeze the second spring, causing the second spring to contract. When the button 312 is released, under the action of the second spring, plates a and b rotate in opposite directions, which resets pressure plate 33 and button 312 at the same time.

[0042] To prevent damage to the circuit board 2 caused by excessive pressure from the pressure plate 33 on the surface of the circuit board 2, a retaining frame 332 is inserted into the bottom of the pressure plate 33. A third spring is provided on the upper surface of the retaining frame 332. The retaining frame 332 is connected to the inner surface of the pressure plate 33 through the third spring. Conductive adhesive 331 is embedded in the bottom of the retaining frame 332. Through the spring connection, the retaining frame 332 can move at the bottom of the pressure plate 33, thereby ensuring that the conductive adhesive 331 is in contact with the surface of the circuit board 2 while avoiding excessive pressure that could damage the circuit board 2.

[0043] Considering that the pressure plate 33 and the movable body 322 are rotatably connected, the pressure plate 33 is prone to tilting when the movable body 322 moves the pressure plate 33 downward, causing the conductive adhesive 331 to fail to properly contact the circuit board 2. To avoid the tilting of the pressure plate 33, side grooves 333 are provided on the outer surfaces of both sides of the pressure plate 33. The bottom ends of the pressure plate 33, i.e., plate a and plate b, are rotatably connected to an anti-deviation body 324. The anti-deviation body 324 includes a T-post and a T-plate that is inserted into the T-post. The two ends of the T-post are rotatably connected to the inner surfaces of the bottom ends of plate a and plate b. The end of the T-plate away from plate a and plate b is located in the side groove 333. The T-plate is slidably connected to the side groove 333. By providing the anti-deviation body 324 that is slidably connected to the pressure plate 33, when the movable body 322 moves the pressure plate 33, the T-plate of the anti-deviation body 324 that is rotatably connected to the bottom ends of plate a and plate b slides in the side groove 333, thereby preventing the pressure plate 33 from tilting when it moves.

[0044] Considering that the symbols and patterns on the surface of button 312 will wear down to the point that the function represented by button 312 cannot be clearly displayed after long-term use, a spherical protrusion is provided at the top of the rod to facilitate the replacement of button 312. Button 312 is made of silicone, and a spherical groove is correspondingly provided at the bottom of button 312. The top of the rod and the bottom of button 312 are engaged in a snap-fit ​​manner. Since button 312 is made of silicone, the spherical protrusion is inserted into the spherical groove at the bottom of button 312 through the snap-fit ​​method, which facilitates the disassembly and assembly of the top of the rod and button 312.

[0045] Considering that remote control may inevitably be bumped or knocked during use, a rubber plate 113 is provided inside the mainboard compartment 112 to prevent damage to the circuit board 2. The circuit board 2 is located inside the rubber plate 113. By providing the rubber plate 113, the energy of the impact can be absorbed when a bump occurs, thereby ensuring that the circuit board 2 will not be damaged by the impact.

[0046] Since the circuit board 2 generates heat when the remote control is working, a flexible thermal pad 21 is attached to the bottom of the circuit board 2 in order to dissipate the heat. The bottom of the flexible thermal pad 21 passes through the rubber plate 113, and the bottom surface of the flexible thermal pad 21 contacts the heat sink 114. The heat sink 114 is located at the bottom of the motherboard compartment 112. A grid plate 115 is provided at the outer end of the bottom of the motherboard compartment 112. By providing a flexible thermal pad 21 at the bottom of the circuit board 2, the flexible thermal pad 21 can conduct the heat generated by the circuit board 2 when it is working, and dissipate it to the outside through the heat sink 114.

[0047] To facilitate the replacement of the input module 3, a cover plate 123 is inserted into the top of the reserved opening 122. The top of the upper frame 311 contacts the bottom of the cover plate 123, and the upper frame 311 and the cover plate 123 are engaged. By inserting and engaging the cover plate 123, the input module 3 inside the reserved opening 122 is exposed, thus facilitating the replacement of the input module 3.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
