Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, and in particular to a waterproof silicone keyboard with a touchpad and left and right buttons. Background Technology

[0002] Keyboards with touchpads and left / right buttons (often called integrated keyboard and touchpad or keyboard and touchpad combos) are primarily suitable for users who prioritize portability, efficiency, or comfort in specific scenarios. Their core value lies in replacing the basic operation functions of a mouse. They eliminate the need for a separate mouse, making them suitable for use in spaces with limited space, or in environments with small work surfaces where a clean and tidy environment is crucial. On one hand, existing keyboards with touchpads and left / right buttons typically have left and right buttons with a width roughly the size of an adult's index finger. This requires precise positioning to press the left and right buttons. On the other hand, existing keyboards often feature integrated silicone covers for dust and water resistance. Designing the left and right buttons wider, such as about the width of two adult index fingers, causes the buttons to lift up on one side when pressed, affecting the user experience. Utility Model Content

[0003] In view of this, this utility model proposes a waterproof silicone keyboard with a touchpad and left and right buttons, and optimizes the assembly structure of the keypad surface of the left and right buttons to solve the above-mentioned problem of warping edges.

[0004] The technical solution of this utility model is a waterproof silicone keyboard with a touchpad and left and right buttons, including a keyboard circuit board, a base plate with a bottom of the keyboard circuit board, and a silicone cover on the top of the keyboard circuit board. The touchpad is located in the middle of the front area of ​​the top surface of the keyboard circuit board corresponding to the keyboard keys. The left side area of ​​the touchpad has a left button, and the right side area of ​​the touchpad has a right button. Each left and right button has a key plate. Both sides of the key plate have hooks. The lower end of the hook is fixed to the keyboard circuit board, and the upper end of the hook has an inverted "L"-shaped hook foot. Both sides of the key plate have hook grooves. When the left and right buttons are naturally popped up, the hook feet hook into the bottom of the hook grooves. The silicone cover has concave and convex silicone cover positions corresponding to the key plate positions.

[0005] Furthermore, the bottom of the touchpad is provided with a U-shaped pad for raising the touchpad. The U-shaped pad is made of acrylic material. The touchpad is connected to the keyboard circuit board via a flexible flat cable. The hole in the middle of the U-shaped pad is used to pass through the flexible flat cable. The silicone cover is provided with a concave and convex touchpad silicone cover position corresponding to the position of the touchpad.

[0006] Furthermore, the hook component includes a rectangular base, one side of which has a vertically downward bent insertion pin, and the other side of the rectangular base opposite to the connecting pin has a vertically upward bent hook pin in the shape of an inverted "L". The hook component is made of copper material by stamping or molding.

[0007] Furthermore, the keyboard circuit board is provided with solder pad holes for inserting the pin portion of the hook component, and the pin portion of the hook component is fixed to the keyboard circuit board by soldering.

[0008] Furthermore, the bottom of the keypad corresponding to the groove is provided with a downwardly protruding thickened area, and the bottom of the thickened area is provided with a vertically downward protruding post. When the keypad is pressed, driving the left or right button to the bottom, the protruding post abuts against the keyboard circuit board.

[0009] Furthermore, the edge of the silicone cover is fixed to the edge of the keyboard circuit board and the edge of the base plate using any one of the following methods: snap-fit, adhesive bonding, or screw connection.

[0010] Furthermore, the top edge of the silicone cover is provided with a waterproof raised rib that forms a closed enclosure along its edge.

[0011] The beneficial effects of this utility model are as follows: The silicone keyboard designed with this technical solution has a touchpad and left and right buttons on its keyboard circuit board. The touchpad and left and right buttons replace mouse control. The left and right button pads utilize a hook assembly structure to lock the pads in place, limiting the pads to their highest position when the left and right buttons are naturally released. This prevents the other side from lifting when one side of the pad is pressed. Furthermore, compared to existing left and right button designs, this solution has a wider pad. This increases the pad area, making it easier and faster for users to click the left or right buttons, thus optimizing the left and right button experience of this type of keyboard.
