Description

Technical Field

[0001] The utility model relates to the technical field of rubber keys, in particular to a high-rebound rubber key. Background Art

[0002] Rubber keys are a common key material in electronic products and are widely used because of their excellent elasticity and touch. They are mainly made of rubber materials and are usually covered on a base of metal or other hard materials to provide better support and durability. Rubber keys are characterized by their soft touch and good feel, which allows users to have a better interactive experience when pressing the keys. In addition, rubber keys also have good anti-slip properties, which can prevent the keys from sliding or falling off during use.

[0003] At present, during the use of rubber keys, since the rubber material body has a certain resistance, the rubber keys have a certain friction during the pressing process, which not only causes a certain resistance to the rebound, resulting in the rubber keys not being able to rebound normally, but also due to the long-term friction of the rubber keys, the friction part of the rubber keys is easily deformed, thereby affecting normal use. Therefore, a high-rebound rubber key is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] See also Figure 1-4 A high-rebound rubber button in this embodiment includes a mounting frame 1, a sleeve 3, a first return spring 4 and a rubber button 5, and a rebound mechanism is provided inside the mounting frame 1.

[0022] The sleeve 3 is fixedly mounted on the bottom inner wall of the mounting frame 1 and there are two of them. The first return spring 4 is fixedly mounted on the bottom inner wall of the mounting frame 1 and there are two of them. The first return spring 4 is slidably connected to the inner wall of the sleeve 3 . The rubber button 5 is movably mounted inside the mounting frame 1 .

[0023] The rebound mechanism includes a grinding kit 6 fixedly installed on the outer wall of the rubber button 5, and the left and right outer walls of the grinding kit 6 are fixedly installed with a first slider 7, the grinding kit 6 is slidably connected to the inside of the mounting frame 1, and the left and right inner walls of the mounting frame 1 are provided with a first slide groove, the first slider 7 is slidably connected to the inside of the first slide groove and the size is adapted, and the left and right inner walls of the mounting frame 1 are fixedly installed with a fixed frame 8, and the two fixed frames 8 are fixedly installed on the outer wall of the sleeve 3 away from the side of the mounting frame 1, and the left and right inner walls of the fixed frame 8 are fixedly installed with a second return spring 9, and the outer wall opposite to the two adjacent second return springs 9 is fixedly installed with an adjustment plate 10.

[0024] The front and rear outer walls of the adjustment plate 10 are fixedly installed with second sliders 11, the front and rear inner walls of the fixed frame 8 are opened with second slide grooves, the second sliders 11 are slidably connected inside the second slide grooves and are adapted in size, the adjustment plate 10 is slidably connected between the front and rear inner walls of the fixed frame 8, two mounting seats 12 are fixedly installed on the outer walls on the opposite sides of two adjacent adjustment plates 10, a rotating shaft 13 is rotatably connected between the two adjacent mounting seats 12, two adjusting rods 14 are fixedly connected to the outer peripheral wall of the rotating shaft 13, and an adjusting shaft 15 is fixedly installed on the side of the adjusting rod 14 away from the rotating shaft 13.

[0025] The outer peripheral wall of the adjusting shaft 15 is rotatably connected with a mounting sleeve 16, and the two mounting sleeves 16 are located between two adjacent adjusting rods 14, and the adjusting rods 14 are installed at an inclined angle. A connecting block 17 is fixedly installed on the outer peripheral wall of the mounting sleeve 16, and a rebound seat 18 is fixedly installed on the top outer wall of the connecting block 17. The rebound seat 18 is movably installed on the bottom outer wall of the rubber button 5, and the distance between the front and rear outer walls of the rebound seat 18 is the same as the distance between the front and rear outer walls of the rubber button 5.

[0026] In this embodiment, the outer wall of the grinding kit 6 becomes smooth after grinding, which greatly reduces the friction and resistance between the grinding kit 6 and the mounting frame 1 when sliding.

[0027] In this embodiment, the height of the top outer wall of the rubber button 5 is higher than the height of the top outer wall of the grinding kit 6 , so the user will not press the grinding kit 6 during use, thereby improving the user's pressing comfort.

[0028] In this embodiment, damping plates are fixedly installed on the inner walls on both sides of the fixed frame 8. The damping plates absorb the vibration and energy generated by the keys during pressing and releasing, thereby reducing the vibration and noise of the keys and improving the user experience. The damping plates can also help control the response speed of the keys, making them smoother when pressed and not too sensitive or slow. A damping ring is provided inside the sleeve 3.

[0029] The working principle of the above embodiment is:

[0030] When the user presses the rubber button 5 downward, the rubber button 5 will move downward, and the first return spring 4 will be compressed and shortened. At this time, after the rebound seat 18 is subjected to downward pressure, the adjusting rod 14 will drive the adjusting shaft 15 and the rotating shaft 13 to rotate synchronously. At this time, the inclination of the adjusting rod 14 will gradually decrease. At the same time, the two adjusting plates 10 and the second second return springs 9 will move toward the inner walls on the left and right sides of the fixed frame 8 respectively. When the user releases the rubber button 5, the adjusting plate 10 will be pushed by the second return spring 9 to move quickly. At this time, the adjusting plate 10 transmits the thrust to the adjusting rod 14. At this time, the adjusting rod 14 will push the rubber button 5 to move upward. At the same time, the first return spring 4 will also push the rubber button 5 upward, thereby improving the resilience of the rubber button 5.
