Description

Technical Field

[0001] The utility model relates to the technical field of external keyboards, and more specifically to an external keyboard which is convenient to be placed on a keyboard surface of a notebook computer. Background Art

[0002] A laptop computer is a relatively small computer. Compared with a desktop computer, a laptop computer has the advantages of being light and portable. However, the performance of a laptop computer of the same price is much worse than that of a desktop computer. A laptop computer integrates a keyboard and a screen. Now most people will choose to buy a laptop computer. Since the keyboard of the laptop computer does not feel good enough and the repair cost of the laptop computer keyboard is expensive after it breaks down, most people choose to connect an external keyboard to the laptop computer. The traditional external keyboard consists of keyboard keys, a keyboard housing and a bracket. Although such traditional devices can provide typing needs, the traditional external keyboard will make the user farther away from the computer screen after being placed on the desktop, which may make the user unable to see the computer screen clearly. Although placing the external keyboard on the keyboard surface of the laptop computer can shorten the distance between the user and the screen, the bottom parts of the external keyboard may touch the keys of the laptop computer itself, which affects the use of the computer to a certain extent, reduces the typing efficiency and brings inconvenience to the user. In order to solve the deficiencies of the prior art, we propose an external keyboard that is easy to be placed on the keyboard surface of a laptop computer. Utility Model Content

[0013] The utility model uses a cleaning component, including a sliding rod. When the sliding rod is rotated, a nut will slide in the direction of the guide rod. Since a magnet is fixedly installed on the upper outer surface of the sliding block, the magnet drives the discus to slide in the direction of the guide rod. The sliding rod is slid left and right, and the brush on the side of the discus is driven to slide under the keyboard button to clean the debris under the keyboard button. By utilizing the above structure, the sliding rod is rotated and slid, so that the discus drives the brush to slide under the keyboard button, and the space under the keyboard button can be cleaned, thereby improving the efficiency of cleaning dirt in the corners of the keyboard, facilitating the user to clean the keyboard, and improving the practicality of the device.

[0026] The bottom shell 27 is fixedly mounted on the lower outer surface of the keyboard case 1, the knob 21 is rotatably connected to the inner wall of the bottom shell 27, the upper rack 23 is slidably connected to the inner wall of the bottom shell 27 and is located on one side of the gear 22, the lower rack 25 is slidably connected to the inner wall of the bottom shell 27 and is located on the other side of the gear 22, the first bracket 24 is slidably connected to the lower inner wall of the bottom shell 27, the second bracket 26 is slidably connected to the lower inner wall of the bottom shell 27 and is located on one side of the first bracket 24, and the outer surface of one side of the limit block 212 is in contact with the outer surface of one side of the first rotating frame 211;

[0027] A gear 22 is fixedly connected to the outer surface of one side of the knob 21, an upper rack 23 is meshed with the outer surface of one side of the gear 22, and a lower rack 25 is meshed with the outer surface of the other side of the gear 22. When the knob 21 is rotated clockwise, the upper rack 23 and the lower rack 25 are brought closer to the middle, and the first bracket 24 and the second bracket 26 are driven to move closer to the middle. When the knob 21 is rotated counterclockwise, the first bracket 24 and the second bracket 26 are driven to separate to both sides.

[0028] The cleaning assembly 3 includes a slide rod 31, a threaded rod 32 is fixedly connected to the outer surface of one side of the slide rod 31, a slide bracket 33 is rotatably connected to the outer wall of the threaded rod 32, a nut 34 is threadedly connected to the outer wall of the threaded rod 32, a guide rod 35 is fixedly connected to the inner wall of the slide bracket 33, a slide block 36 is slidably connected to the outer wall of the guide rod 35, a magnet 37 is fixedly installed on the upper outer surface of the slide block 36, and a discus 38 is arranged directly above the magnet 37;

[0029] The slider 36 is slidably connected to the outer wall of the guide rod 35 , so that the slider 36 can only slide along the direction of the guide rod 35 .

[0030] The slide bar 31 is slidably connected to the inner wall of the bottom shell 27, the slide bracket 33 is slidably connected to the inner wall of the bottom shell 27, the lower outer surface of the slider 36 is fixedly connected to the upper outer surface of the nut 34, the upper outer surface of the magnet 37 is attached to the lower outer surface of the keyboard case 1, and the lower outer surface of the discus 38 is attached to the upper outer surface of the keyboard case 1;

[0031] A threaded rod 32 is fixedly connected to the outer surface of one side of the sliding rod 31, and a sliding bracket 33 is rotatably connected to the outer wall of the threaded rod 32. The sliding bracket 33 is slidably connected to the inner wall of the bottom shell 27. Since the sliding rod 31 is slidably connected to the inner wall of one side of the bottom shell 27, when the sliding rod 31 is slid left and right along the inner wall of the bottom shell 27, the sliding bracket 33 will be driven to slide left and right. Since the lower outer surface of the sliding block 36 is fixedly connected to the upper outer surface of the nut 34, when the sliding rod 31 is rotated, the nut 34 will slide along the direction of the guide rod 35. Since a magnet 37 is fixedly installed on the upper outer surface of the sliding block 36, the magnet 37 will slide along the direction of the guide rod 35 at this time.

[0032] Among them, rubber pads are installed on the lower outer surfaces of the two support blocks 28, rubber pads are installed on the lower outer surfaces of the second rotating frame 29 and the first rotating frame 211, and two limiting protrusions are fixedly connected on both sides of the first bracket 24 and the second bracket 26;

[0033] Rubber pads are installed on the lower outer surfaces of the two support blocks 28, and rubber pads are installed on the lower outer surfaces of the second rotating frame 29 and the first rotating frame 211. When the external keyboard is placed on the keyboard surface of the laptop computer, collision between them can be avoided. Since two elastic limiting protrusions are fixedly connected to both sides of the first bracket 24 and the second bracket 26, the second rotating frame 29 and the first rotating frame 211 can be restricted from rotating freely when they are raised and folded.

[0034] Among them, a brush is fixedly installed on the side of the discus 38;

[0035] A brush is fixedly mounted on the side of the discus 38 , and when the discus 38 slides on the upper outer surface of the keyboard case 1 , the brush is driven to clean the debris.

[0036] The working process of the utility model is as follows:

[0037] First, turn the knob 21. Since the outer surface of one side of the knob 21 is fixedly connected to the gear 22, the outer surface of one side of the gear 22 is meshed with the upper rack 23, and the outer surface of the other side of the gear 22 is meshed with the lower rack 25. At this time, the upper rack 23 and the lower rack 25 move toward the middle or separate to both sides, and drive the first bracket 24 and the second bracket 26 to slide until the distance between the first bracket 24 and the second bracket 26 is close to the width of the keyboard surface of the user's laptop computer. The second rotating frame 29 and the first rotating frame 211 are rotated to support them, and their bottoms are aligned. The two sides of the laptop keyboard surface are placed without keys, and the two support blocks 28 are placed on both sides of the laptop touch panel. At this time, the external keyboard can be stably placed on the keyboard surface of the laptop, and the slide bar 31 is rotated, and the nut 34 will slide along the direction of the guide rod 35. Since the upper outer surface of the slider 36 is fixedly mounted with a magnet 37, the magnet 37 drives the discus 38 to slide along the direction of the guide rod 35. Sliding the slide bar 31 left and right will drive the brush on the side of the discus 38 to slide under the keyboard button and clean the debris under the keyboard button.
