DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1:

[0029] As Figures 1-6 shown, the present invention provides a character-protruding keycap structure, including a keycap body 1, a groove 10 is opened at the top end of the keycap body 1, and four support protrusions 11 are fixedly arranged at the bottom end inside the groove 10;

[0030] Inside the groove 10, there is a first rubber sheet 12 and a first cover plate 3. The first cover plate 3 is arranged at the top of the first rubber sheet 12, and the top of the first cover plate 3 is flush with the top of the keycap body 1.

[0031] The bottom end of the first rubber sheet 12 contacts the top end of the support protrusion 11. The first cover plate 3 is connected to the support protrusion 11 by screws, and the first rubber sheet 12 is clamped between the support protrusion 11 and the first cover plate 3.

[0032] At the top end of the first rubber sheet 12, there is a rubber protrusion 5 fixed. The rubber protrusion 5 extends to the top of the first cover plate 3, and the rubber protrusion 5 is in the shape of a character.

[0033] The first rubber sheet 12 is fixed inside the groove 10, and the first cover plate 3 is placed at the top of the first rubber sheet 12. The rubber protrusion 5 on the first rubber sheet 12 passes through the first cover plate 3 and protrudes from the top of the first cover plate 3, thus forming a protruding character. Supported by the support protrusion 11, the middle part of the first rubber sheet 12 is in a suspended state, and the first rubber sheet 12 has elasticity. Therefore, in the normal state, the rubber protrusion 5 protrudes from the top of the first cover plate 3. When tapped by a finger, the downward pressure of the finger will cause the rubber protrusion 5 to retract downward into the groove 10, and the first rubber sheet 12 will also be deformed by the force. When the finger leaves, the elastic force of the first rubber sheet 12 makes the rubber protrusion 5 return to its original position, thus achieving the purpose of buffering between the rubber protrusion 5 and the finger, reducing the wear of the rubber protrusion 5 during use. At the same time, even if the rubber protrusion 5 is worn, it can be replaced together with the first rubber sheet 12 without disassembling and replacing the entire keycap body 1, which is more convenient.

[0034] Embodiment 2:

[0035] Once one of the keycap bodies 1 is damaged, a temporary substitute can be quickly found. As shown in FIGS. Figure 1 、 2 5, 6, the first cover plate 3 can also be replaced by a second cover plate 6, and the first rubber sheet 12 is replaced by a second rubber sheet 13. The second cover plate 6 is connected to the support protrusion 11 by screws, and the second rubber sheet 13 is clamped between the second cover plate 6 and the support protrusion 11.

[0036] A writing area 14 is inlaid at the top end of the second rubber sheet 13, and characters are written on the writing area 14. A transparent sheet 7 made of acrylic material is inlaid on the second cover plate 6. Through the transparent sheet 7, the characters on the writing area 14 can be observed. The transparent sheet 7 is located directly above the writing area 14, and the transparent sheet 7 protrudes from the top of the second cover plate 6.

[0037] Replace the first rubber sheet 12 with the second rubber sheet 13, write characters at the writing area 14, and cover the second cover plate 6 on the top of the second rubber sheet 13. During use, the characters on the writing area 14 can be observed through the transparent sheet 7, thus playing a role in distinguishing the keycap body 1. The protrusion of the transparent sheet 7 from the surface of the second cover plate 6 can also enable the keycap body 1 to have a tactile feeling of character protrusion during use. And in this way, once one of the keycap bodies 1 is damaged, there is no need to find the corresponding keycap body 1 according to the characters for replacement. Just reserve spare keycap bodies 1 with a blank writing area 14, and rewrite the corresponding characters at the writing area 14 for replacement, which improves the replacement speed and is more convenient.

[0038] To improve the cleaning efficiency of the keyboard, as Figure 1 、 5 shown, a notch is provided on the front side of the keycap body 1, and a rubber plug 4 is provided at the notch. After removing the rubber plug 4, air can be blown into the interior of the keycap body 1.

[0039] After opening the rubber plug 4, the notch on the keycap body 1 can be exposed. When cleaning the keyboard, the dust and impurities inside the keycap body 1 can be sucked out through the notch, avoiding the keycap body 1 from blocking the dust at its bottom and affecting the cleaning effect.

[0040] To adjust the height of the keycap body 1, as Figure 3 、 5 shown, a connection component 8 is provided inside the keycap body 1. The connection component 8 includes a threaded column 801 fixedly provided at the top end inside the keycap body 1, and a sleeve 802 is sleeved on the bottom end of the threaded column 801 through a thread;

[0041] A connection protrusion 803 is fixedly provided at the bottom end of the sleeve 802, and a plug-in slot 804 is provided at the bottom end of the connection protrusion 803. The connection protrusion 803 is connected to the shaft body on the keyboard key through the plug-in slot 804.

[0042] During use, the keycap body 1 is connected to the shaft body of the keyboard through the connection component 8 at its bottom. The protruding part of the keyboard shaft body is snapped into the plug-in slot 804 at the bottom end of the connection protrusion 803 to achieve the purpose of connection. By rotating the sleeve 802, the sleeve 802 can move relative to the threaded column 801, thereby adjusting the overall height of the connection component 8, and thus adjusting the height of the entire keycap body 1, realizing the adjustment of the height of the keycap body 1, and improving the use effect.

[0043] When disassembling the keycap body 1, it is necessary to avoid the fixture from damaging the shaft body, as Figure 1 、 3, as shown in Fig. 4, two sets of limiting mechanisms are provided at the bottom end of the keycap body 1, and the number of each set of limiting mechanisms is two. The two limiting mechanisms in the same group are symmetrically arranged at the lower edges on the front and rear sides of the keycap body 1;

[0044] The limiting mechanism includes a guide frame 2 fixedly arranged at the bottom end of the keycap body 1. A blocking protrusion 9 is arranged inside the guide frame 2, and the blocking protrusion 9 is fixedly arranged at the bottom end of the keycap body 1, which is convenient for fixing the keycap body 1 when disassembling the keycap body 1.

[0045] When disassembling the keycap body 1, it is necessary to clamp the fixture at the bottom end of the keycap body 1 and pull the keycap body 1 upward. When the strip-shaped fixture is connected to the keycap body 1, it is caught inside the two symmetrical guide frames 2 on the front and rear sides and is located between the guide frame 2 and the blocking protrusion 9 inside it. The guide frame 2 blocks the fixture to prevent it from moving towards the central position at the bottom of the keycap body 1, thereby preventing the fixture from clamping the shaft body of the keyboard. And the blocking protrusion 9 blocks the fixture to prevent it from moving towards the outside of the keycap body 1 and separating from the keycap body 1. In this way, the fixture can be safely and firmly fixed to the keycap body 1, so that when the keycap body 1 is disassembled from the keyboard, it does not affect the shaft body of the keyboard.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
