[0018] The following will be combined with the attached Figures 1 to 4 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides an anti-fall remote control through improvement. Figure 1-Figure 4 As shown, a drop-proof remote control is characterized in that it includes a remote control body 1, a device hole 3 is opened on the left outer wall of the remote control body 1, an assembly groove is opened on the upper surface of the remote control body 1, and eleven assembly grooves are set, and a button 7 is set inside the assembly groove, a rubber sheet 5 is fixedly connected to the inner wall of the remote control body 1, a circuit board 6 is set inside the remote control body 1, and the circuit board 6 is connected to the remote control body 1 through the rubber sheet 5, the button 7 is located above the circuit board 6, the vertical center line of the device hole 3 coincides with the vertical center line of the circuit board 6, a rubber pad 8 is fixedly connected to the inner wall of the remote control body 1, and the rubber pads 8 are evenly distributed on the inner wall of the lower end of the remote control body 1, and the rubber pads 8 are located below the circuit board 6; the remote control body 1 is a metal shell, and the metal shell improves the remote control body. The solidity of the body 1 prevents the outer shell from being damaged when the remote control body 1 is hit, thereby ensuring the integrity of the appearance of the remote control body 1. When the remote control body 1 is hit, the circuit board 6 is displaced by inertia, and the displacement of the circuit board 6 is limited by the rubber sheet 5 to prevent the circuit board 6 from contacting the inner wall of the remote control body 1 and preventing the circuit board 6 from colliding with the remote control body 1, thereby ensuring the integrity of the circuit board 6 and the normal use of the remote control body 1, improving the drop resistance of the remote control body 1, and improving the service life of the remote control body 1. When the button 7 is pressed, the circuit board 6 will move downward with the button 7, resulting in poor contact between the circuit board 6 and the button 7. The downward movement distance of the circuit board 6 is limited by the rubber pad 8 to ensure the contact between the button 7 and the circuit board 6.

[0020] The inner wall of the specific device hole 3 is fixedly connected with a glass 4; the glass 4 prevents large debris from entering the remote control body 1 through the device hole 3 and affecting the range of movement of the circuit board 6, ensuring that the circuit board 6 has sufficient buffering space when the remote control body 1 is hit.

[0021] Specifically, the outer wall of the remote control body 1 is fixedly connected with a rubber pad 2, and the rubber pads 2 are distributed on both sides of the remote control body 1; the rubber pads 2 increase the friction of the outer wall of the remote control body 1, making it easier for people to grasp the remote control body 1, and increasing the friction of the outer wall of the remote control body 1 to prevent the remote control body 1 from slipping in people's hands.

[0022] Specifically, the outer wall of the remote control body 1 is fixedly connected with a wear-resistant layer 9; the wear-resistant layer 9 is a tungsten carbide alloy coating, which improves the wear resistance of the outer wall of the remote control body 1, prevents the outer wall of the remote control body 1 from being scratched, and ensures the integrity and aesthetics of the outer wall of the remote control body 1.

[0023] Specifically, the outer wall of the wear-resistant layer 9 is fixedly connected with a self-cleaning layer 10; the self-cleaning layer 10 is a nano self-cleaning coating, which has the bionic principle of the special structure of the "lotus leaf self-cleaning effect". Since the lotus leaf has a hydrophobic and non-absorbent surface, rainwater falling on the leaf surface will form water droplets due to the effect of surface tension. In other words, the contact angle between water and the leaf surface will be greater than 90 degrees. As long as the leaf surface is slightly tilted, the water droplets will roll away from the leaf surface. Therefore, even after a downpour, the surface of the lotus leaf can always remain dry. In addition, the rolling water droplets will take away some dust and sludge particles by the way, achieving a self-cleaning effect. The nano material used in the nano self-cleaning coating has extremely low surface tension, and thus has strong hydrophobicity and anti-fouling properties. The self-cleaning layer 10 reduces the adhesion of dirt and ensures the cleanliness of the outer wall of the remote control body 1.

[0024] Working principle: First, the remote control body 1 is a metal shell. The metal shell improves the firmness of the remote control body 1, prevents the shell from being damaged when the remote control body 1 is hit, and ensures the integrity of the appearance of the remote control body 1. When the remote control body 1 is hit, the circuit board 6 is displaced by inertia, and the rubber sheet 5 is used to limit the displacement of the circuit board 6 to prevent the circuit board 6 from contacting the inner wall of the remote control body 1 and preventing the circuit board 6 from colliding with the remote control body 1, thereby ensuring the integrity of the circuit board 6 and the normal use of the remote control body 1, improving the drop resistance of the remote control body 1 and the service life of the remote control body 1. When the button 7 is pressed, the circuit board 6 will move downward with the button 7, resulting in poor contact between the circuit board 6 and the button 7. The rubber pad 8 limits the downward movement distance of the circuit board 6 to ensure the contact between the button 7 and the circuit board 6. Then, the glass 4 is used to prevent large debris from entering the remote control body 1 through the equipment hole 3 and affecting the range of movement of the circuit board 6, ensuring that the circuit board 6 has sufficient buffering space when the remote control body 1 is hit. The rubber pad 2 improves the remote control The friction of the outer wall of the remote control body 1 makes it easier for people to grasp the remote control body 1, improves the friction of the outer wall of the remote control body 1, and prevents the remote control body 1 from slipping in people's hands. Then the wear-resistant layer 9 is a tungsten carbide alloy coating. The wear resistance of the outer wall of the remote control body 1 is improved through the wear-resistant layer 9, which prevents the outer wall of the remote control body 1 from being scratched, ensuring the integrity and aesthetics of the outer wall of the remote control body 1. Finally, the self-cleaning layer 10 is a nano self-cleaning coating with a bionic principle of a special structure of the "lotus leaf self-cleaning effect". Since the lotus leaf has a hydrophobic and non-absorbent surface, water falling on the leaf surface Rainwater on the lotus leaf will form water droplets due to the effect of surface tension. In other words, the contact angle between water and the leaf surface will be greater than 90 degrees. As long as the leaf surface is slightly tilted, the water droplets will roll away from the leaf surface. Therefore, even after a downpour, the surface of the lotus leaf can always remain dry. In addition, the rolling water droplets will take away some dust and mud particles by the way, achieving a self-cleaning effect. The nano material used in the nano self-cleaning coating has extremely low surface tension, and thus has strong hydrophobic and anti-fouling properties. The self-cleaning layer 10 reduces the adhesion of dirt and ensures the cleanliness of the outer wall of the remote control body 1.
