Referring to FIG. 3 , the side wall 22 of the casing 20 is formed with a quasi-elliptical receiving portion 220 for accommodating the sliding key 40 , and the sliding key 40 can slide in the receiving portion 220 along the long side of the quasi-elliptical shape. The receiving portion 220 is formed by inwardly recessing from the side wall 22 of the casing 20 , and has a periphery 222 and a bottom 224 surrounded by the periphery 222 . Both the periphery 222 and the bottom 224 are approximately elliptical. The bottom 224 continuously defines a first cutout 226 and two second cutouts 228 , and the second cutouts 228 are located on two sides of the first cutout 226 and communicate with the first cutout 226 . The height of the first cutout 226 is higher than that of the second cutout 228 .

Please refer to FIG. 4 to FIG. 5 in combination, the sliding key 40 is integrally formed, and has an operating portion 42 , an actuating portion 44 and a positioning portion 46 . The touch portion 44 extends vertically from the operation portion 42 , and the positioning portion 46 perpendicularly crosses the touch portion 44 and is spaced from the operation portion 42 .

The operating portion 42 is a type of elliptical sheet for the operator to act on the first surface 420 to move the slide key 40 . The operation part 42 is housed in the receiving part 220 , and can reciprocate in the receiving part 220 along a sliding direction parallel to its longitudinal direction. A plurality of protrusions 422 vertically extend from the first surface 420 of the operating portion 42 , and the protrusions 442 can increase the static friction force between the operator and the first surface 420 to achieve an anti-slip effect. A recess 424 is formed on the first surface 420 at the same time, and the recess 424 can be aligned with the printed or etched logo/text (not shown) on the side wall 22 of the housing 20 to indicate the current status of the electronic device 99 . The operating portion 42 has a second surface 426 opposite to the first surface 420 , and two convex ribs 428 are formed on the second surface 426 , and the two convex ribs 428 are respectively distributed on two distal ends of the second surface 426 . The two convex ribs 428 can reduce the contact area between the second surface 426 and the bottom 224 of the receiving portion 220 , so as to reduce the friction force between the two and make the sliding key 40 slide in the receiving portion 220 more smoothly.

The trigger part 44 vertically extends from the center of the second surface 426 of the operation part 42 and is used for touching the toggle switch 52 on the circuit board 50 . The maximum width of the trigger portion 44 is slightly smaller than or equal to the width of the first cutout 226 , and can extend out from the first cutout 226 , which includes a connecting plate 440 and two tail fins 442 . Both the connecting plate 440 and the tail fin 442 extend vertically from the second surface 426 , and the two tail fins 442 are relatively parallel and clamp the connecting plate 440 therebetween. The connecting plate 440 can enhance the structural strength of the tail fin 442 of the triggering portion 44 . A fin 444 and a rounded corner 446 are formed at the end of each fin 442 . The protruding fins 444 and the fillets 446 are respectively formed on two adjacent corners of the empennage 442 . The protruding fin 444 can trigger the toggle switch 52 , and the rounded corner 446 can make it easier for the trigger part 44 to pass through the first cutout 226 of the receiving part 220 during installation.

The positioning portion 46 extends from the touch portion 44 at a distance from the operating portion 42 , and its extending direction is parallel to the sliding direction of the sliding key 40 . The maximum width of the positioning portion 46 is slightly smaller than or equal to the maximum width between the two second slits 228 , and can pass through the space formed by the two second slits 228 and the first slit 226 . The positioning part 46 can hold the bottom 224 of the receiving part 220 together with the operating part 42. The positioning part 46 includes an extension plate 460 and two side wings 462. The extension plate 460 and the connecting plate 440 of the trigger part 44 are perpendicular to each other. The two side wings 462 are respectively Extending from the two side ends of the extension plate 460 along the same extension direction as the protruding fin 444 of the trigger part 44, the height of the side wings 462 is greater than the height of the second cutout 228, so that the side wings can be blocked by the bottom 224 of the receiving part 220, thereby It is prevented from slipping out of the second cutout 228 . Each side wing 462 has a wedge block 464 at its tail, and the initial height of the wedge block 464 is less than or equal to the height of the second cutout 228 , which makes it easier for the side wing 462 to pass through the second cutout 228 during installation.

Please refer to FIG. 6 , the toggle switch 52 is welded on the circuit board 50 , and the toggle switch 52 has a toggle pin 520 protruding from the circuit board 50 . The toggle switch 52 can be a two-stage switch or a multi-stage switch, and the current state of the electronic device 99 can be switched between two or more states by sliding or shaking the toggle pin 520 . The toggle pin 520 is restricted by the two protruding fins 444 of the trigger portion 44 , and slides or shakes along with the slide key 40 , thereby changing the state of the toggle switch 52 .

Referring to FIG. 7 , the process of installing the slide key 40 on the housing 20 will be described in detail below.

Firstly, the protruding fin 444 on the tail fin 442 of the sliding key 40 extends obliquely from the first cutout 226 in the receiving portion 22 into the casing 20 . Then, the sliding key 40 is rotated around the contact point between the protruding fin 444 and the bottom 224 of the receiving portion 220 , so that the rounded corner 446 of the empennage 442 passes through the first cutout 226 smoothly. After the protruding fin 444 and the fillet 446 on the empennage 442 pass through the first cutout 226 smoothly, the position of the sliding key 40 changes from the previous oblique direction to the direction perpendicular to the side wall 22 of the casing 20, and the entire trigger part 44 The tail end enters the housing 20.

After the above steps are completed, the positioning portion 46 is directly opposite to the first cutout 226 and the second cutout 228 . The wedge-shaped piece 464 of the positioning portion 46 gradually enters the second cutout 228 , so that the side wings 442 can be squeezed through the second cutout 228 , and are blocked by the bottom 224 of the receiving portion 220 and cannot escape from the second cutout 228 . After the side wings 442 are squeezed into the second cutout 228 , the operating part 42 is slidably received in the receiving part 220 , and the bottom 224 of the receiving part 220 is clamped between the positioning part 44 and the operating part 42 .

Please refer to FIG. 2 and FIG. 6 again. After the sliding key 40 is installed on the housing 20 , the housing 20 can cooperate with the base 30 containing the circuit board 50 . The casing 20 covers the base 30 to enclose the circuit board 50 inside the base 30 . At this time, the sliding key 40 on the casing 20 is just opposite to the toggle switch 52 on the circuit board 50 , and the toggle pin 520 of the toggle switch 52 is constrained between the two tail fins 442 .

When the electronic device 99 wants to change its current working mode during use, the sliding key 40 is moved along the sliding direction, and the sliding key 40 moves in the receiving portion 220 . The toggle pin 520 of the toggle switch 52 moves together with the slide key 40 under the constraint of the tail fin 442 , so that the working mode of the electronic device 99 is switched through the toggle switch 52 .

As an optional implementation, if the structure permits, the tail 442 of the trigger part 44 can be omitted, and the task of triggering the toggle switch 52 can be performed by the side wings 462 of the positioning part 46 . In addition, the sliding key 42 can also adopt the structure of a single fin 442 instead of the structure of the two fins 442 and the connecting plate 444 . In this case, the toggle pin 520 of the trigger switch 52 is pushed by the fins 442 to switch states.

Obviously, the above-mentioned sliding key 40 adopts an integral molding to simplify its structure. As mentioned above, the sliding member 40 is easy to install on the housing 20 of the electronic device 99. At the same time, due to the resistance of the side wings 462 and the bottom 224 of the receiving portion 220, the sliding member 40 is not easy to disengage from the housing 20, and the use is more stable. .

The slider 40 described above can be widely used in various electronic devices, such as mobile computers, game machines, portable CD players, and so on.
